As shown in fig. 2 to 4, the present embodiment provides a cutter arranging system, which can be applied to a numerical control drilling machine for processing a PCB board. The cutter arranging system comprises a cutter management module, a cutter library module 1 and a cutter arranging module 2.
The tool management module records tool information of all tools required by machining and tool information of a workpiece to be machined. The cutter information comprises the types and the residual using times of the cutters, and the cutter diameters of the cutters of different types are different. The cutter information comprises the type of the required cutter, the use sequence and the total use times of each type of cutter.
Specifically, before the workpiece to be machined (in this embodiment, a PCB board is taken as an example), information of all holes to be drilled on the PCB board needs to be obtained. The information of the holes comprises the hole diameter and the number of the holes corresponding to each hole diameter.
And determining a cutter of a required model according to the aperture sizes of all the holes on the plate. Illustratively, the holes to be processed on the PCB board include holes T01, T02, … …, T0N, and the respective holes T01, T02, … …, T0N have different diameters. The aperture of the T01 hole is 0.2mm, and then a cutter with the cutter diameter of 0.2mm is required to be selected for the T01 hole; the aperture of the T02 hole is 0.35mm, a cutter with the cutter diameter of 0.35mm is required to be selected for the T01 hole, and so on.
Each tool has a useful life and the useful life is known from experimentation. The used times of the cutter are subtracted from the service life of the cutter, namely the residual used times of the cutter. For example, a tool with a diameter of 0.2mm has a life of 10 times and after it has drilled 5 holes of 0.2mm, it is used 5 times (i.e. 10 times minus 5 times that have been used).
The information of the total use times in the knife information can be obtained according to the number of the holes with each size. For example, if the number of holes of 0.2mm is 30, then a tool of 0.2mm diameter is used 30 times, i.e., the total number of times of use of the 0.2mm tool is 30 times.
The number of each type of tool can be determined according to the number of holes of each size and the service life of the corresponding type of tool. For example, a total number of uses of 0.2mm tools is 30 and its lifetime is 10, at least 3 tools with a 0.2mm tool diameter are required. The total use times of the 0.35mm cutter is 50 times, the service life of the cutter is 11 times, and at least 5 cutters with the cutter diameter of 0.35mm are needed. Considering that the cutter may break during the drilling process, 1-3 spare cutters can be added.
According to the arrangement sequence of all holes on the PCB, the use sequence of all types of cutters can be determined.
In this embodiment, the type of the required tool, the order of use, and the total number of uses of each type of tool can be obtained by reading the information in the machining program.
In this embodiment, a tool whose total number of times of use is less than a first threshold is defined as an unusual tool, and a tool whose total number of times of use is not less than the first threshold is defined as an unusual tool. The first threshold may be set according to the cutter setting requirement, for example, 10 times.
Referring to fig. 3, the tool magazine module 1 includes a base 11, and a first tool magazine unit, a second tool magazine unit, a third tool magazine unit, and a fourth tool magazine unit disposed on the base 11. The first tool magazine unit, the second tool magazine unit, the third tool magazine unit and the fourth tool magazine unit each comprise at least one cutter head 14 for carrying tools, in this embodiment 50 tools are carried by each cutter head 14. The cutterhead 14 of the first magazine unit is used for placing very common tools, and the cutterhead 14 of the second magazine unit is used for placing common tools.
Specifically, the cutter management module can generate a cutter arranging template according to the cutter information and the cutter information, and the arranging template can be used for knowing the placing position of each type of cutter. When the workshop is used for arranging the cutters for the first cutter storage unit and the second cutter storage unit, the cutter arranging mechanism is used for placing common cutters in the first cutter storage unit and placing the common cutters in the second cutter storage unit according to cutter position information contained in the cutter arranging template. Illustratively, if it is known by taking the gang tool template: in the common tool matrix, the 1 st row and the 1 st column are 3mm tools, and then the tool arrangement mechanism grabs a 3mm tool in the 3mm tool storage box and places the 3mm tool in the 1 st row and the 1 st column of the first tool magazine unit, and then the same is performed until the common tools meeting the processing requirements are well arranged in the first tool magazine unit and the common tools meeting the processing requirements are well arranged in the second tool magazine unit. Subsequently, the first magazine unit and the second magazine unit loaded with tools may be transferred to the base station 11 of the drilling machine and fixed.
In the formal machining process, the cutter arranging module 2 can grab and transport cutters to be machined according to cutter information and cutter arranging templates, update the residual use times of the machined cutters into cutter information, put the machined cutters into the cutter library module 1 according to the updated cutter information, and feed back the current positions of the cutters to the cutter management module.
Specifically, the cutter arranging module 2 can acquire the type of the cutter required to be used in the current machining by using cutter information, and acquire the placement position of the cutter of the type in the cutter magazine module 1 by using cutter position information contained in the cutter arranging template, so that the cutter of the type is accurately grasped, and the cutter is transported to a cutter placement position to be machined. The drilling machine is provided with a main shaft, and the lower end of the main shaft is provided with a chuck. The main shaft drives the chuck to move to the position where the cutter to be processed is placed to grasp the cutter of the model, so as to process the PCB below the main shaft. After the machining is completed, the spindle transfers the tool to the machined tool placement position, and at the same time, the tool arrangement module 2 updates the remaining number of uses of the tool.
Illustratively, the cutter arranging module 2 knows that the current machining requires a cutter of 0.35mm by using cutter information, and then, a cutter with a cutter diameter of 0.35mm can be grasped in the cutter magazine module 1 to be placed at the cutter placing position to be machined. The spindle clamps the cutter, and places the cutter at a machined cutter placing position after 8 holes with the diameter of 0.35mm are drilled on the PCB. The service life of the 0.35mm cutter is 11 times, the cutter arranging template records the remaining use times of the cutter to be 3 times (the 11 times are subtracted by 8 times), and the cutter information of the cutter is fed back to the cutter management module. If the cutter is grabbed again for 3 times to drill holes, the residual using times of the cutter are 0.
For the tool on the machined tool placement site, the tool placement module 2 will place it in the tool magazine module 1 according to its latest remaining usage number information. Specifically, the cutter with the residual use times not being 0, whether the cutter is a very-used cutter or a common cutter, is put back to the original position and waits for subsequent processing and use. Placing the rest of the non-common tools with the use times of 0 in a fourth tool magazine unit; the common tool with the remaining use number of 0 is selectively placed back in the second tool magazine unit or placed in the fourth tool magazine unit. That is, the tools with the remaining use times of 0 are placed in the second tool magazine unit and the fourth tool magazine unit in a concentrated manner, and when the tools with the remaining use times of 0 are replaced, the tools in the second tool magazine unit and the fourth tool magazine unit can be replaced in a concentrated manner.
After the machined tool is placed in the tool magazine module 1, the tool arranging module 2 feeds back the current position of the tool to the tool management module. For example, the 5mm unusual tools originally placed in the 2 nd row and 3 rd column of the first tool magazine unit are transferred to the 1 st row and 1 st column of the fourth tool magazine unit by the tool arrangement module 2 after the remaining use times are 0, and then the latest positions of the unusual tools are fed back to the tool management module by the tool arrangement module 2. When the 5mm very-used cutter is used later, the cutter arranging module 2 can know that the cutter of the model does not exist in the 2 nd row and the 3 rd column in the first cutter magazine unit through the information of the cutter management module, and then the cutter of the model at other positions is grabbed.
In actual machining, cutterhead 14 in both the first magazine unit and the second magazine unit are modular. For example, in one cutter head 14 of the second magazine unit, there are 30 number 1 cutters and 20 number 2 cutters, and when the cutters of the second magazine unit are replaced, the cutter head 14 needs to be replaced as a whole, instead of replacing or supplementing only an insufficient number of cutters. That is, the new cutterhead 14 (30 number 1 cutters, 20 number 2 cutters, and the order of placement is identical to that of the old cutterhead 14) is replaced as a whole with the old cutterhead 14. However, in the replaced old cutterhead 14, some of the cutters still have not reached the service life, and the cutters cannot be fully utilized, resulting in waste of the cutters.
It should be noted that, the tools with the remaining use number of 0 include tools to be ground and tools to be scrapped. The tool to be ground can be reused after grinding, but the current processing can not be reused. The scrapped cutter is a broken and broken cutter, and the subsequent reprocessing cannot be continued.
In this embodiment, when updating the common tools in the first tool magazine unit and the common tools in the second tool magazine unit, the tool setting module 2 can transfer the common tools and the non-common tools with the remaining use times of not 0 to the third tool magazine unit, so as to avoid the tools with the remaining use times of not 0 (i.e. tools with the service lives of not reaching) from being replaced together, improve the utilization rate of the tools, and reduce the processing cost.
Alternatively, referring to fig. 2, in the present embodiment, the base 11 is of a hollow rectangular parallelepiped structure. The cutter arranging module 2 comprises a cutter grabbing manipulator 21 arranged on the base 11, wherein the cutter grabbing manipulator 21 is used for grabbing and transporting cutters in the cutter magazine module 1. The base 11 is provided with a first linear module along its longitudinal direction. The grasping tool manipulator 21 includes a support frame 211 and a grasping tool mechanism 212 provided on the support frame 211. The supporting frame 211 is connected to the output end of the first linear module and spans across the base 11 along the width direction of the base 11. The support 211 is provided with a second linear module along the width direction of the base 11, and the knife grabbing mechanism 212 is disposed on the second linear module. The tool grabbing mechanism 212 comprises a lifting driving piece and a clamping jaw arranged at the output end of the lifting driving piece, wherein the clamping jaw is used for clamping tools in the tool magazine module 1. Through mutually perpendicular's first straight line module and second straight line module and lift driving piece, can realize clamping jaw along base station 11 length direction, base station 11 width direction and vertical removal to can transport the cutter to appointed position.
Further, the cutter arranging module 2 further comprises a counting unit and a position recording unit which are in communication connection with the cutter management module. The counting unit is used for recording the residual use times of the tool used in the current machining and updating the recorded information to the tool management module. The position recording unit is used for recording the latest position information of the used cutter and feeding back to the cutter management module.
Referring to fig. 3 and 4, the tool magazine module 1 further includes a first housing 12 and a second housing 13 on the base 11. The first base 12 is used for loading the first tool magazine unit and the third tool magazine unit, and the second base 13 is used for loading the second tool magazine unit and the fourth tool magazine unit.
Wherein, the second base 13 is detachably connected to the base 11. Because the frequency of usage of the common tools is higher than that of the very common tools, the consumption speed and the replacement frequency of the common tools are also higher, and the tools with the remaining usage times of 0 in the fourth tool magazine unit also need to be replaced in time, so that the second tool magazine unit and the fourth tool magazine unit are placed in the same base body, the second base body 13 can be detached from the base 11 when the second tool magazine unit and the fourth tool magazine unit are updated, the whole set of cutterhead 14 loaded with the common tools is replaced to the second base body 13, the required very common tools are supplemented in the cutterhead 14 of the fourth tool magazine unit, and then the updated second base body 13 is reinstalled on the base 11.
Alternatively, in the present embodiment, referring to fig. 4, 5 and 6, a driving mechanism 31 and a pressing member 32 are provided on the base 11, and the pressing member 32 is connected to an output end of the driving mechanism 31. After the second base 13 is placed on the base 11, the driving mechanism 31 can drive the pressing member 32 to lift and rotate, so that the pressing member 32 can rotate above the second base 13 and press the second base 13 on the base 11, thereby realizing the fixation of the second base 13. As shown in fig. 7, when the second seat 13 needs to be disassembled, the driving mechanism 31 drives the pressing member 32 to rise first to release the pressing effect on the second seat 13, and then the driving mechanism 31 drives the pressing member 32 to rotate to the side of the second seat 13, so as to avoid the pressing member 32 from being mistakenly touched when the second seat 13 is removed.
Further, referring to fig. 6, the second housing 13 includes a bottom wall, two first side portions disposed opposite to each other, and two second side portions disposed opposite to each other. The bottom wall, the two first side portions and the two second side portions enclose a loading slot, and the cutterhead 14 of the second magazine unit and the fourth magazine unit is placed in the loading slot. The loading slot is only opened at the upper end, so that a better limiting effect can be achieved on the cutterhead 14 placed in the loading slot. The pressing member 32 presses the entire second housing 13 against the base 11 by pressing the upper wall of the first side portion. The first side part is convexly arranged on the bottom wall of the second seat body 13, so that the thickness of the first side part is larger, the strength and the compression resistance are higher, and the second seat body 13 can be prevented from being crushed.
By providing the driving mechanism 31 and the pressing member 32 on the base 11, automatic attachment and detachment of the second base 13 can be achieved, reducing manual intervention. In this embodiment, the driving mechanism 31 is preferably a rotary pressing cylinder, and can drive the pressing member 32 to lift and rotate simultaneously.
The frequently used tools are used at a lower frequency in the machining process, and correspondingly, the consumption speed and the replacement frequency are also lower. The third tool magazine unit is used as a transfer area, and is used for placing tools with the residual times not being 0 when tools of the first tool magazine unit and the second tool magazine unit are updated, so that disassembly is not needed in the machining process. In this embodiment, the first base 12 is connected to the base 11 by a threaded fastener, and the first base 12 is not generally detached during actual processing. And when the unusual tools in the first tool magazine unit need to be updated, transferring the unusual tools with the residual times of not 0 in the first tool magazine unit to a third tool magazine unit. The cutter arranging mechanism in the workshop can arrange the whole set of the unusual cutters in the fourth cutter magazine unit of the second base 13 replaced next time according to the unusual cutter position information contained in the cutter arranging template. After the second housing 13 is mounted to the base 11, the cutter-setting module 2 on the drill will transfer the common cutters from the fourth magazine unit into the first magazine unit. In this way, it is possible to replace the whole set of very-used tools or the whole set of very-used tools by simply removing the second seat 13. In addition, the first base 12 is connected to the base 11 by a threaded fastener, and the first base 12 can be detached when necessary (e.g., when damaged or overhauled).
Of course, in other embodiments, the first base 12 may be connected to the base 11 by other detachable connection methods, or the first base 12 may be non-detachably connected to the base 11, such as welded to the base 11.
In this embodiment, optionally, the first base 12 is provided with a first information tag, where the first information tag is used to record tool information and position information of the tools in the first tool magazine unit and the third tool magazine unit. The second base 13 is provided with a second information tag, and the second information tag is used for recording tool information and position information of tools in the second tool magazine unit and the fourth tool magazine unit.
The cutter arranging module 2 is in communication connection with the first electronic tag and the second electronic tag so as to acquire cutter information and position information of the cutter. Illustratively, the cutter arranging module 2 knows through cutter information of the cutter management module that the current hole needs to be machined by a cutter of 0.5mm, and further knows through the first information tag and the second information tag the position information of the cutter of 0.5mm in the cutter magazine module 1, so that the cutter of 0.5mm is grabbed to a cutter to be machined placing position. If there are more than one 0.5mm knife, the knife arranging module 2 grabs one knife according to a certain sequence (see the content in the follow-up knife arranging method).
From the foregoing, the counting unit in the cutter arranging module 2 can update the recorded latest remaining use times of the cutters into the cutter management module, and the position recording unit in the cutter arranging module 2 can feed back the recorded latest position information of the cutters to the cutter management module. The cutter management module is in communication connection with the first information tag and the second information tag through the reader-writer so as to update the latest cutter information and position information of the cutter into the first information tag and the second information tag through a writing unit of the reader-writer, so that the first information tag and the second information tag can record the latest information of the cutter on the first base 12 and the second base 13, and the cutter arranging module 2 can accurately acquire the latest position information of a cutter of a certain model when the cutter is grabbed, and the cutter is prevented from being grabbed by mistake; and when the cutter arranging module 2 grabs the cutter, the counting unit can accurately acquire the information of the residual use times of the cutter so as to update the calculated latest residual use times into the cutter management module after the cutter is machined, and the cutter management module updates the cutter information into the first information label and the second information label, thereby forming an information interaction process.
In this embodiment, the first information tag and the second information tag are RFID (radio frequency identification) electronic tags, and the RFID electronic tags can be adhered to the first base 12 and the second base 13.
In this embodiment, referring to fig. 3 to 5, the base 11 is further provided with a tool detection module 4. The tool inspection module 4 is disposed at an interval from the first housing 12 (the second housing 13) in the width direction of the base 11. The knife inspection module 4 is provided with a knife inspection unit 42, an air blowing unit 43 and at least two knife holders 41, wherein the knife holders 41 can be used for placing a knife to be processed (namely, the knife holder is used as the processed knife placing position), and can be used for placing a knife after processing (namely, the knife holder to be processed is used as the processed knife placing position). The gang tool module 2 is capable of transferring tools between the tool holder 41 and the tool magazine module 1.
Illustratively, referring to fig. 3, three tool holders 41 are provided on the tool detection module 4, a first tool holder, a second tool holder, and a third tool holder in this order from left to right. The tools are numbered as tool 1, tool 2, tool 3 and tool … … according to the order of use of the tools. During processing, the cutter arranging system sequentially places the No. 1 cutters and the No. 2 cutters on the first cutter rest and the second cutter rest, and the main shaft of the drilling machine firstly clamps the No. 1 cutters on the first cutter rest and sends the No. 1 cutters to the cutter detecting unit 42 for detection. The tool detection unit 42 is configured to detect whether the model and the tool state of the tool are normal, and feed back the detection result to the tool management module. That is, the tool detection unit 42 detects whether the tool diameter of the tool No. 1 matches the tool information for the current machining, and detects whether the tool No. 1 is in a broken state or a broken state. And if any one of the cutter model and the cutter state is not satisfactory, transferring the cutter No. 1 to a fourth cutter magazine unit by the cutter arranging module 2. If the cutter model and the cutter state are qualified, the main shaft clamps the No. 1 cutter to process the PCB plate, and meanwhile, the cutter arranging module 2 grabs the No. 3 cutter to a third cutter rest according to cutter information.
After the machining of the cutter No. 1 is completed, the spindle transfers the cutter No. 1 to the blowing unit 43, and the blowing unit further blows and cleans the cutter No. 1 to remove chips and dust attached to the cutter No. 1. Then, the spindle places the cleaned cutter No. 1 again in the cutter inspection unit 42 to detect whether the cutter No. 1 is broken or broken, and feeds back the detection result to the cutter management module. And then, the spindle replaces the detected No. 1 cutter on the first cutter rest, clamps the No. 2 cutter on the second cutter rest, and executes the detection and processing procedures. Meanwhile, the cutter arranging module 2 places the No. 1 cutter on the first cutter frame in the cutter magazine module 1 according to the information of the residual using times, and grabs the No. 4 cutter in the cutter magazine module 1 to place on the first cutter frame. And the like until the processing of a group of PCB boards is completed.
In this embodiment, by providing three tool holders 41, two tools used for subsequent processing can be sequentially discharged, and the two tools are placed on the two tool holders 41 by the tool arranging module 2. In the above example, in the machining process of the No. 1 cutter, the No. 2 cutter and the No. 3 cutter which are used subsequently are placed on the second cutter rest and the third cutter rest, and the first cutter rest is empty and is used for temporarily storing the No. 1 cutter after machining is completed, so that the machining efficiency is effectively improved.
Of course, in other embodiments, two, four and more tool holders 41 may be provided, and may be set according to specific production requirements. If two tool holders 41 are provided, during a machining process of a certain tool, the tool setting module 2 may place a tool to be used later on the corresponding tool holder 41.
Optionally, the tool setting system further comprises an alarm module in communication with the tool management module. The cutter management module reads the information recorded by the first electronic tag and the second electronic tag through the reader-writer, the total number of cutters with the residual use times of not 0 in each type in the cutter library module 1 can be counted, when the number of the cutters with the residual use times of not 0 in any type is lower than a second threshold value, the cutter management module can send a signal to the main control system of the drilling machine, and the main control system further sends an instruction according to the signal, so that the alarm module sends an alarm signal, thereby reminding workshop personnel of insufficient cutter stock, and facilitating timely updating of cutters in the cutter library module 1.
The embodiment also provides a processing device (such as a drilling machine for processing a PCB) comprising the cutter arrangement system. The processing equipment can record the residual use times of the cutter in real time, and the cutter is replaced or placed in the fourth tool magazine unit according to the latest residual use times information of the cutter, so that the cutter is convenient to replace. Moreover, when the cutter is replaced, the third cutter magazine unit can be used for storing the cutters with the residual use times not being 0, so that the cutters which do not reach the service life are prevented from being taken away and ground, and the cutter utilization rate is improved.
As shown in fig. 8 and 9, the present embodiment further provides a cutter arranging method, which adopts the cutter arranging system as described above to arrange cutters, and includes the following steps:
s1, acquiring cutter information of a workpiece to be machined and cutter information of all cutters required by machining;
s2, generating a cutter arranging template according to cutter information and cutter information, and placing all cutters into the cutter library module 1 according to the cutter arranging template;
s3, grabbing a cutter for processing according to the cutter information and the cutter arranging template, and updating cutter information of the processed cutter;
s4, placing the processed tool into the tool magazine module 1 according to the updated tool information, and recording the current position of the tool.
In step S1, the tool information includes a model number and the remaining number of uses. The cutter information comprises the type of the required cutter, the use sequence and the total use times of each type of cutter. The cutter model and the cutter information can be obtained by reading the information in the processing program, and the description is omitted here.
In step S2, the step of generating a cutter arranging template according to the cutter information and the cutter information, and placing all cutters into the cutter magazine module 1 according to the cutter arranging template specifically includes:
s21, setting a first threshold according to the cutter information, the cutter accommodating quantity of the first cutter magazine unit and the second cutter magazine unit.
By way of example, the total number of times of use of each type of cutter can be obtained by using the cutter information, the total number of times of use is sequentially arranged from high to low and is recorded as a type 1 cutter, a type 2 cutter, a type 3 cutter, a type 4 cutter, a type 5 cutter and a type 6 cutter … …, and the corresponding cutter numbers are sequentially 50, 30, 10 and 3 … …. I.e. the type 1 tool is used most frequently, in the number of 50, and so on. In this embodiment, the number of the first magazine units and the second magazine units is 150 (each including 3 cutterheads 14). The sum of the numbers of the first five types of cutters is 150, which just corresponds to the accommodating number of the second cutter magazine unit (if the sum of the numbers of the first five types of cutters with the highest total using times cannot exceed the accommodating number of the second cutter magazine unit), and the total using times corresponding to the 5 types of cutters is the first threshold value.
S22, putting the cutters with the total use times less than the first threshold value into the first cutter library unit as the unusual cutters, and putting the cutters with the total use times not less than the first threshold value into the second cutter library unit as the unusual cutters.
In the above example, the total number of times of use of the first five types of tools is not less than the first threshold value, which is a common tool. The total number of uses of the class 6 tool and all tools thereafter is less than a first threshold, which is a very common tool. When the cutter arranging template is generated, not only the common cutters and the common cutters are divided, but also the arrangement sequence of the common cutters and the common cutters is generated according to cutter information. Prior to the main machining, the tool setting mechanism of the shop places the common tools in the cutterhead 14 of the first magazine unit and the common tools in the cutterhead 14 of the second magazine unit according to the setting order. In the initial processing, the third tool magazine unit and the fourth tool magazine unit do not place any tools.
Optionally, in step S3, the step of gripping the tool for processing according to the tool information and the tool setting template includes:
s31, obtaining the residual use times and position information of all tools of the type required by current machining in the tool magazine module 1;
s32, acquiring the number of times of use of a cutter required by current machining;
s33, if a cutter with the remaining use times equal to the use times exists, grabbing the cutter to process a workpiece to be processed; otherwise, selecting a cutter with the residual use times larger than the use times and the difference between the residual use times and the use times is the smallest to process the workpiece to be processed.
For example, in the current processing stage, according to the cutter information of the PCB board, it is known that 5 holes with the aperture of 0.35mm are required to be drilled on the PCB board, and then the required type of cutter is a cutter with the cutter diameter of 0.35mm, and the required use times are 5 times. Therefore, the cutter bar module 2 needs to grasp the cutter of the cutter diameter of 0.35mm in the magazine module 1 and transfer it onto the cutter holder 41. The cutter arranging module 2 obtains the information of the residual using times and the position information of all the cutters with the thickness of 0.35mm in the cutter magazine module 1 through the first electronic tag and the second electronic tag (the cutter arranging template is recorded on the first electronic tag and the second electronic tag). If there is a 0.35mm tool with a remaining number of uses of exactly 5 times (i.e. the number of uses required for the current machining), the tool-setting module 2 preferably grabs the tool and transfers it to the tool holder 41, and the spindle then grabs the tool on the tool holder 41 for drilling. After the completion of the machining, the remaining number of uses of the 0.35mm tool became 0. If the remaining use times of all the 0.35mm tools in the tool magazine module 1 are 3 times, 6 times, 8 times and 10 times respectively, the tool grabbing module preferentially grabs the 0.35mm tools with the remaining use times of 6 times and transfers the tools to the tool rest 41. After the completion of the machining, the remaining number of uses of the 0.35mm tool became 1.
According to the cutter grabbing rule, on the premise that 5 holes with the diameter of 0.35mm can be drilled at one time without cutter replacement, cutters with the minimum residual use times are preferentially consumed, so that the use sequence of the cutters is more reasonable, and the utilization rate of the cutters is effectively improved.
In step S33, the satisfactory tools in the third magazine unit are grasped preferentially.
Specifically, if there are a plurality of tools with the remaining use times equal to the use times and at least one tool is located in the third tool magazine unit, grabbing tools with corresponding models in the third tool magazine unit to process to-be-machined parts.
In the above example, if there is a 0.35mm tool with the remaining number of uses of 5 times in the third tool magazine unit, the 0.35mm tool with the remaining number of uses of exactly 5 times in the third tool magazine unit is preferentially grasped to preferentially consume the tools in the third tool magazine unit.
Or on the premise that no cutter with the residual use times equal to the use times exists, if a plurality of cutters with the residual use times larger than the use times and the difference between the residual use times and the use times is smallest, and at least one cutter is positioned in the third cutter library unit, the corresponding cutter in the third cutter library unit is grabbed to process the workpiece to be processed.
In the above example, if there is no tool with the remaining use number of times being exactly 5 times in the tool magazine unit, and the 0.35mm tool meeting the condition that "the remaining use number of times is greater than the use number of times and the difference between the remaining use number of times and the use number of times is minimum" is located in the first tool magazine unit and the third tool magazine unit, respectively, then the 0.35mm tool meeting the condition in the third tool magazine unit is preferably grasped.
Alternatively, in other embodiments, the tool setting module 2 always takes the tools in the third tool magazine unit to perform machining preferentially, regardless of the number of remaining uses of the tools in the third tool magazine unit. Illustratively, 3 tools with the usage times of 0.35mm exist in the third tool magazine unit, the remaining usage times are respectively 2 times, 3 times and 4 times (all are smaller than the usage times required by the current machining), and the tool arranging module 2 sequentially grabs the tools with the usage times of 0.35mm, the remaining usage times of which are 2 times and 3 times, so as to finish the current machining. And grabbing the tools of the required types in the first tool magazine unit and the second tool magazine unit after all the tools in the third tool magazine unit are consumed.
Referring to fig. 9, in step S4 of the present embodiment, the specific steps of placing the machined tool into the tool magazine module 1 according to the updated tool information include:
S41, when the cutter is a very-used cutter, if the residual use times of the cutter are 0, the cutter is selectively placed into a fourth cutter library unit, and otherwise, the cutter is placed back to the original position;
as shown in fig. 9, after the machining of the unusual tools in the first tool magazine unit is completed, if the remaining use times are not 0, the tool setting module 2 returns the unusual tools to the original position in the first tool magazine unit, and the subsequent machining can be continued; if the remaining number of uses is 0, the cutter arranging module 2 transfers the cutter arranging module to the fourth cutter magazine unit, and then the cutter arranging module and the common cutter in the second cutter magazine unit are replaced together.
S42, when the cutter is a common cutter, if the residual use times of the cutter are 0, the cutter is placed in a fourth cutter magazine unit or a home position, otherwise, the cutter is placed back to the home position.
As shown in fig. 9, after the machining of the common tools in the second tool magazine unit is completed, if the remaining use times are not 0, the tool setting module 2 returns the common tools to the original position in the second tool magazine unit, and the subsequent machining can be continued; if the remaining number of uses is 0, the cutter arranging module 2 returns the cutter arranging module to the original position of the second cutter magazine unit or transfers the cutter arranging module to the fourth cutter magazine unit.
Specifically, in this embodiment, the states in which the number of times of remaining use of the tool is 0 include a state to be ground and a state to be scrapped. In step S42, if the common tool reaches the state to be ground, the tool setting module 2 returns the common tool to the original position of the second tool magazine unit, and the common tool can be used continuously after grinding; if the common cutter is in a scrapped state (broken or broken), the cutter arranging module 2 is put into the fourth cutter magazine unit, and cannot be used continuously, and scrapping treatment is needed.
It should be noted that, the very common tools, whether in the to-be-ground state or the scrapped state, are all placed in the fourth tool magazine unit.
After finishing processing a plurality of groups of PCB boards, the method further comprises the step S5: and replacing the cutter with the residual using times of 0. The consumption speed and the replacement frequency of the common tool are far higher than those of the non-common tool, and when the common tool is replaced, the second base 13 needs to be disassembled, and the second tool magazine unit and the fourth tool magazine unit on the second base 13 are updated at the same time.
Specifically, the specific steps when the common tool is replaced include:
s51, confirming the remaining use times of the common tools in the second tool magazine unit.
Specifically, the cutter arranging module 2 may obtain the remaining usage frequency information of all the common cutters in the second cutter magazine unit through the second electronic tag. At this time, the second tool magazine unit includes the common tools to be ground and the common tools with the remaining use times less than 0.
S52, grabbing the common tools with the remaining use times not being 0 in the second tool magazine unit to the third tool magazine unit so that the remaining use times of the remaining common tools in the second tool magazine unit are 0.
Specifically, the cutter arranging module 2 transfers all the common cutters with the remaining use times not being 0 to the third cutter magazine unit, and then the remaining common cutters in the second cutter magazine unit are all cutters in a to-be-ground state and can be used normally after grinding.
And S53, replacing the common tool in the second tool magazine unit and replacing the unusual tool in the fourth tool magazine unit.
Specifically, the second base 13 is detached from the base 11, the cutterhead 14 in the second tool magazine unit is replaced as a whole, the replaced second tool magazine unit is a whole set of common tools, and all the common tools in the fourth tool magazine unit are replaced with new tools.
For example, when the second base 13 is replaced, the fourth magazine unit includes 5 pieces of common tools in a scrapped state, 2 pieces of non-common tools in a to-be-ground state (the tool diameters are 1mm and 3mm, respectively), and 1 piece of non-common tools in a scrapped state (the tool diameter is 3.5 mm). And when the tool is replaced, all the tools in the fourth tool magazine unit are taken down, new tools with the thickness of 1mm, 3mm and 3.5mm which are very used are supplemented into the fourth tool magazine unit, and 5 common tools in the scrapped state are not required to be supplemented, and scrapped after being taken down.
S54, the unusual tools in the fourth tool magazine unit are grabbed and transported to the first tool magazine unit.
Specifically, after the new second seat 13 is mounted on the base 11, the cutter arranging module 2 grabs the common cutters in the fourth cutter magazine unit and places the common cutters in the first cutter magazine unit according to the cutter arranging template to empty the fourth cutter magazine unit, and in the later processing stage, the fourth cutter magazine unit only places the cutters with the remaining use number of 0.
The frequency of use and the consumption speed of the very-used tool are slower, and the very-used tool with the residual use frequency of 0 in the previous processing stage can be supplemented in the fourth tool magazine unit when the very-used tool is updated each time, so that the whole set of the very-used tool is replaced at a lower frequency, and the very-used tool is replaced together with the very-used tool when being replaced.
Specifically, in step S52, further including:
and grabbing the unusual tools with the residual use times not being 0 in the first tool magazine unit to a third tool magazine unit so as to empty the first tool magazine unit.
The remaining use times of all the tools in the first tool magazine unit are not 0, so that when the whole set of the tools is replaced, the tool setting template transfers all the tools in the first tool magazine unit to the third tool magazine unit so as to empty the first tool magazine unit.
After the second seat 13 is disassembled, the cutter head 14 in the second tool magazine unit is replaced integrally, and the whole set of common tools is arranged in the fourth tool magazine unit. At this time, the updated second base 13 is provided with a set of common tools and a set of unusual tools. After the second base 13 is mounted on the base 11, the cutter arranging module 2 transfers the unusual cutters in the fourth cutter magazine unit to the first cutter magazine unit according to the cutter arranging template. In this embodiment, the whole set of the very-used tools can be replaced while the very-used tools are replaced, and the first seat 12 does not need to be detached alone to replace the very-used tools, so that the tool changing process is simplified.
After the whole set of the unusual tools and the usual tools are updated, the unusual tools and the usual tools with the residual use times not being 0 are placed in the third tool magazine unit. During processing, the tools in the third tool magazine unit can be grasped preferentially, or the tools in the tool magazine module 1 can be grasped according to the rule of grasping tools described in step S3. Further, after the machining is finished, if the residual use times are not 0, the tool in the third tool magazine unit is put back to the original position; if the remaining use times are 0, transferring to a fourth tool magazine unit. After finishing processing, the common cutters in the third tool magazine unit are put back to the original position if the residual use times are not 0; if the state to be ground is reached, the tool is placed in the second tool magazine unit (when the second tool magazine unit is provided with an empty tool setting groove) or the fourth tool magazine unit (when the second tool magazine unit is not provided with an empty tool setting groove); and if the common cutters in the third tool magazine unit are in a scrapped state after processing, transferring the cutter arranging template into the fourth tool magazine unit.
