Description
Technical Field
The invention relates to the technical field of circuit board manufacturing equipment, in particular to a circuit board production system and a collapsible separating plate device.
Background
With the continuous upgrade of electronic products, high-density interconnection printed boards are widely used, the thickness of the adopted core board is thinner and thinner, and the expansion and shrinkage coefficients of the boards have strict requirements, particularly the application of a layer-by-layer laminating technology. Because the manufacturing process of the circuit board is increased and the expansion and shrinkage change in the production process is large, the expansion and shrinkage management and control are very important.
In the manufacturing process of the circuit board, the internal stress accumulated on the board due to the action of the external force can be avoided, so that the purpose of reducing the internal stress can be achieved. Due to the internal stress generated by the change of the environmental temperature and humidity or the physical property of the circuit board material, the shrinkage stress generated by the resin curing of the circuit board, such as the thermal stress generated when the external temperature changes due to the mismatching of the thermal expansion coefficients of the components such as resin, glass fiber, copper foil, filler and the like. The existence of internal stress influences the dimensional stability of the board, and the board is unevenly expanded and contracted due to the wet stress generated by the change of the environmental humidity and the like.
However, since the expansion and shrinkage of the circuit board are not uniform, and the circuit board is classified only according to whether the expansion and shrinkage exist, for the circuit board with the multi-layer structure having the expansion and shrinkage, the expansion and shrinkage drill belt is not matched with the production board before drilling, which has a great influence on the production efficiency of the circuit board. In order to solve the problem that the collapsible drill belt of the circuit board is not matched with the production board before drilling, workers need to measure the hole distance of the target hole and calculate the hole distance, a new collapsible drill belt is manufactured again, the production board which is subjected to sample making in the process needs material changing production, and the waiting time in the middle is long. If the sample of the new collapsible drill belt is found to be still not in accordance with the requirements, the previous sample making process is repeated again, time and labor are wasted, and the drill belt can only take out a very small part of batch products for measurement and calculate the average value of the products, so that the production efficiency and the precision of the circuit board are low.

In the collapsible plate-dividing apparatus 10, when the plate is conveyed to the detection position of the target hole light source detection mechanism 200 along with the first feeding assembly 810, the target hole light source detection mechanism 200 measures the actual target distance of the target hole of the plate, and calculates the difference between the actual target distance and the predetermined target distance to obtain the collapsible value of the plate; when the second conveying assembly conveys the plate from the target hole light source detection mechanism 200 to the position corresponding to the first alignment plate assembly 510 before the second conveying assembly conveys the plate from the target hole light source detection mechanism 200 to the input end of the plate separation mechanism 600, the first alignment plate assembly 510 pushes and positions the plate to the processing position of the slotting mechanism 300, so that the slotting mechanism 300 processes the mark slots, and at this time, the control mechanism 400 controls the slotting mechanism 300 to process a predetermined number of mark slots according to the expansion and contraction value. The plate dividing mechanism 600 outputs the plates to the blanking mechanism 700 in a classified manner according to the number of the marking grooves of the plates, so that the plates are divided rapidly and accurately, the marking mechanism 900 is added to mark the expansion and contraction coefficients on the plates, the control mechanism 400 is networked to realize data sharing, corresponding expansion and contraction tools such as a drill belt and an expansion and contraction film can be manufactured in time, and the production efficiency of the plates is improved; because the plate is thinned and divided, the problem that the expansion and shrinkage drilling belt is not matched with the production plate before drilling is solved by simply classifying the traditional circuit board according to whether the expansion and shrinkage are carried out, the situation of repeated proofing and debugging is avoided, and the production efficiency and the precision of the circuit board are improved.
As shown in fig. 1, further, the target hole light source detection mechanism 200 includes an emitter 210 and a receiver 220, and the emitter 210 and the receiver 220 are respectively disposed on two sides of the first feeding assembly 810. The transmitter 210 is used to transmit signals and the receiver 220 is used to receive signals to measure the actual target distance of the board. It is understood that in other embodiments, the aperture light source detection mechanism 200 may also employ prior art aperture detection mechanisms to measure the actual target distance of the panel.
In one embodiment, the control mechanism 400 calculates the difference between the actual target distance and the predetermined target distance to obtain the expansion/contraction value of the plate, and calculates the quotient between the actual target distance and the predetermined target distance to obtain the expansion/contraction coefficient of the plate. Because the circuit board passes through the pressfitting operation when production, the plate has certain harmomegathus value after the pressfitting. After the plate is pressed and hit, the target hole light source detection mechanism 200 can measure the actual target distance of the target hole. The control mechanism 400 calculates the difference between the actual target distance and the predetermined target distance to obtain the corresponding expansion and contraction value of the plate. The principle of measuring and calculating the expansion and contraction value is as follows: as shown in FIG. 2, the plate is designed with target holes, which are a hole, b hole, c hole and d hole, respectively, wherein d hole is a mistake-proofing target hole, a hole and b hole are on the same straight line in the longitudinal direction, b hole and c hole are on the same straight line in the transverse direction, so that the measurement can be performed only by using the center points of the three holes, namely a hole, b hole and c hole. The designed target hole distance of the plate is X/Y, and the target hole distance obtained by actual production of the plate is X1/Y1, wherein the delta X is X1-X, and the delta Y is Y1-Y. If the absolute value of the delta X is larger than the absolute value of the delta Y, the expansion and contraction value of the plate is the absolute value of the delta X, namely the absolute value of the delta X is used as the expansion and contraction interval of the plate; on the contrary, the expansion and contraction value of the plate is the absolute value of Δ Y, i.e. the absolute value of Δ Y is used as the expansion and contraction interval of the plate. For example, when X is 563.22mm, Y is 324.26mm, X1 is 563.32mm, and Y1 is 324.20mm, Δ X is 0.1mm, Δ Y is-0.06 mm, and the plate expansion and contraction value is 0.1 mm.
In one embodiment, the plate members are classified into four types, i.e., a first type plate, a second type plate, a third type plate and a fourth type plate, according to the range of the expansion and contraction values. If the plate member is a kind of plate, the number of the marking grooves is 0, that is, the grooving mechanism 300 does not form the marking grooves on the plate member, and the kind of plate is a non-collapsible plate and is also a qualified plate. If the plate member is a second-type plate, the number of the marking grooves is 1, that is, one marking groove is formed on the plate member by the grooving mechanism 300. If the plate member is a three-type plate, the number of the marking grooves is 2, that is, the grooving mechanism 300 forms two marking grooves on the plate member. If the plate member is a four-type plate, the number of the marking grooves is 3, that is, the grooving mechanism 300 forms three marking grooves on the plate member.
In one embodiment, when the expansion and contraction value is 0, the number of the marking grooves is 0. When the expansion and contraction value is larger than 0 and smaller than a first set value, the number of the marking grooves is 1. When the expansion and contraction value is greater than or equal to a first set value and less than a second set value, the number of the marking grooves is 2. When the expansion and contraction value is larger than or equal to a second set value, the number of the marking grooves is 3. So, to the plate of the different expansion and contraction values of same type, the figure in mark groove is different, is favorable to the discernment of post production, and then realizes dividing the board fast, improves and divides board efficiency. That is, for different types of boards, four different expansion and contraction sections may be set, with the expansion and contraction value being 0 as the first expansion and contraction section, the expansion and contraction value being greater than 0 and less than the first set value as the second expansion and contraction section, the expansion and contraction value being greater than or equal to the first set value and less than the second set value as the third expansion and contraction section, and the expansion and contraction value being greater than or equal to the second set value as the fourth expansion and contraction section.
In one embodiment, the first setting is 0.05mm to 0.1mm, which makes the collapsible plate device 10 better suited for different types of plate members. In one embodiment, the second setting is 0.1mm to 0.15mm, which makes the collapsible plate device 10 better suited for different types of plate members. In one embodiment, the first setting is 0.05mm, and the second setting is 0.1mm, so that the collapsible split board apparatus 10 is better suitable for high-density interconnection printed boards. In one embodiment, the first setting is 0.1mm, and the second setting is 0.15mm, so that the collapsible printed board device 10 is better suitable for non-high-density interconnection printed boards.
In one embodiment, although the plate members are divided into four types of plates according to the size of the expansion and contraction value, the first set value and the second set value are different in size for different types of plate members, such as a high-density interconnection printed board or a non-high-density interconnection printed board. For example, for a high-density interconnection printed board, the first setting value is set to 0.05mm, and the second setting value is set to 0.1 mm. And for a non-high-density interconnection printed board, the first setting value is set to 0.1mm, and the second setting value is set to 0.15 mm.
As shown in fig. 1, 4 and 5, further, the plate separating mechanism 600 includes a conveying assembly 640, a first plate separating assembly 610, a second plate separating assembly 620 and a third plate separating assembly 630. The first, second and third splitter assemblies 610, 620 and 630 are sequentially disposed on the machine body 100 side by side, wherein the first splitter assembly 610 is adjacent to the output end of the second feeding assembly 820, and the first, second and third splitter assemblies 610, 620 and 630 are all disposed adjacent to one side of the conveying assembly 640. The blanking mechanism 700 includes a first blanking assembly 710 disposed adjacent one side of the conveyor assembly and adjacent the output end of the conveyor assembly, and three second blanking assemblies 720 disposed side-by-side and adjacent the other side of the conveyor assembly 640. Three second discharging assemblies are respectively disposed corresponding to the first dividing plate assembly 610, the second dividing plate assembly 620 and the third dividing plate assembly 630. The control ends of the first plate subassembly 610, the second plate subassembly 620, and the third plate subassembly 630 are all electrically connected to the control mechanism 400. When the plate transported by the transport assembly 640 is a first-class plate, that is, the number of the mark slots formed on the plate is 0, the first plate dividing assembly 610, the second plate dividing assembly 620 and the third plate dividing assembly 630 do not move, so that the plate is automatically transported to the first feeding assembly along with the third feeding assembly. When the plate transported by the transporting assembly 640 is a second type plate, that is, the number of the mark slots formed on the plate is 1, the first plate assembly 610 acts to push the plate of the transporting assembly 640 to the second blanking assembly corresponding to the first plate assembly 610. When the plates conveyed by the conveying assembly 640 are three types of plates, that is, the number of the marking slots formed on the plates is 2, the second plate dividing assembly 620 acts to push the plates of the conveying assembly 640 to the second blanking assembly corresponding to the second plate dividing assembly 620. When the plate conveyed by the conveying assembly 640 is a four-type plate, that is, the number of the mark grooves formed on the plate is 3, the third plate dividing assembly 630 acts to push the plate of the conveying assembly 640 to the second blanking assembly corresponding to the third plate dividing assembly 630, so that plate division of the plate is realized. In the present embodiment, the first, second, and third plate assemblies 610, 620, and 630 are all cylinder push plate assemblies.

The first push plate 512 and the second push plate 514 are arranged in parallel, and the first push plate 512 and the second push plate 514 are respectively positioned at two sides of the slotting mechanism 300. The first and second push plates 512 and 514 are used to push the two sides of the plate respectively to clamp and position the plate at the processing position of the slotting mechanism 300. It is understood that the first flush plate assembly 510 pushes the plate member to a different position from the processing position of the grooving mechanism 300, so that the grooving mechanism 300 processes a different number of the mark grooves on the plate member for subsequent plate division. In this embodiment, a fixing frame 110 is disposed on the machine body, the first driving cylinder is disposed on the fixing frame, and the first pushing plate and the second pushing plate are both slidably connected to the fixing frame. The first driving cylinder drives the first push plate and the second push plate to slide relative to the fixed frame respectively, so that the first push plate and the second push plate are close to or far away from each other.

As shown in FIG. 3, in one embodiment, the plate has a target hole distance X/Y, and the actual plate has a target hole distance X1/Y1, the expansion and contraction coefficients of the plate are: rx X1 ÷ X ÷ transverse expansion coefficient, Ry Y1 ÷ Y ÷ longitudinal expansion coefficient. For example, when X is 563.22mm, Y is 324.26mm, X1 is 563.32mm, and Y1 is 324.20mm, the lateral expansion and contraction coefficient Rx of the expansion and contraction coefficient of the plate is 100.018, and the longitudinal expansion and contraction coefficient Ry of the expansion and contraction coefficient of the plate is 99.982. The lateral expansion coefficient Rx and the longitudinal expansion coefficient Ry are both transmitted to the marking mechanism 900 through the control mechanism 400, and the marking mechanism 900 marks the plate with a mark "Rx equals 100.018, Ry equals 99.982". Specifically, the marking mechanism 900 marks the expansion and contraction coefficient of the plate member on one side of the plate member. In this embodiment, the marking mechanism 900 is a laser marking mechanism 900, so that the marking mechanism 900 can mark the plate in a non-contact manner, and the plate can be conveniently and quickly processed. In other embodiments, the marking mechanism 900 may also be a machined marking mechanism 900.

In one embodiment, the collapsible split plate apparatus 10 further comprises a drilling mechanism (not shown), a control end of the drilling mechanism is electrically connected to the control mechanism 400, and the drilling mechanism retrieves a corresponding collapsible tool according to the collapsible coefficient output by the control mechanism 400. The collapsible tool comprises a collapsible drill belt, a pattern transfer collapsible film and a resistance welding collapsible film. It can be understood that corresponding collapsible tools are different for different types of plates, and during drilling and machining, the expansion and contraction tools are directly taken for use without waiting, so that the problems that after material changing, no tool is used for drilling belts and films, or a large amount of data needs to be manually measured to obtain the expansion and contraction coefficients and the like are solved, and the production efficiency of the plate is greatly improved. In one embodiment, the drilling mechanism includes a drilling mechanism body and a retrieval box in which a plurality of different collapsible tools are stored, and an output control terminal of the retrieval box is electrically connected to the control mechanism 400. When the calling box receives the command of the expansion and contraction coefficient of the control mechanism 400, the calling box outputs the corresponding expansion and contraction tool. The user can use the harmomegathus instrument on drilling mechanism main part rapidly, makes drilling mechanism main part can be accurate processing go out blind hole or through-hole on the plate, has improved the manufacturing efficiency and the precision of circuit board.
For the high-density interconnection printed board, in one embodiment, the minimum diameter of the blind hole or the hole ring of the through hole of the board is 75 μm, so that the hole position accuracy requirement of the drilling mechanism for drilling the board is ± 50 μm. Experiments prove that when the tolerance limit of drilling is +/-50 mu m, the distance between the holes and the PAD edge is only 25 mu m, when the expansion and contraction of the whole plate reaches +/-50 mu m, the holes are just tangent to the PAD, the single sides of the plate are respectively allocated to 25 mu m, the expansion and contraction of the plate exceeds +/-50 mu m, and meanwhile, when the tolerance of drilling reaches +/-50 mu m, the holes are just tangent to the PAD of the inner layer. To ensure the accuracy of the drilling of the inner PAD, a split of + -50 μm is preferred, i.e. a first set value of 0.05mm and a second set value of 0.1 mm. When the expansion and contraction value is 0, the number of the marking grooves is 0. When the expansion and contraction value is more than 0 and less than 0.05mm, the number of the marking grooves is 1. When the expansion and contraction value is greater than or equal to 0.05mm and less than 0.1mm, the number of the marking grooves is 2. When the expansion and contraction value is greater than or equal to 0.1mm, the number of the marking grooves is 3.
For non-high density interconnect printed boards, in one embodiment, the minimum diameter of the blind or through hole ring of the board is 175 μm, so that the hole position accuracy requirement of the drilling mechanism for drilling the board is ± 100 μm. Experiments have shown that to ensure the accuracy of the inner PAD of the drilled hole, a split of ± 100 μm is preferred, i.e. the first set value is 0.1mm and the second set value is 0.15 mm. When the expansion and contraction value is 0, the number of the marking grooves is 0. When the expansion and contraction value is larger than 0 and smaller than 0.1mm, the number of the marking grooves is 1. When the expansion and contraction value is greater than or equal to 0.1mm and less than 0.15mm, the number of the marking grooves is 2. When the expansion and contraction value is greater than or equal to 0.15mm, the number of the marking grooves is 3.
In fact, for the same type of plate, like a batch of high-density interconnected printed boards of the same type, the corresponding expansion and contraction values are different due to the slight difference of the debugging ratio of the material components for manufacturing the plate, and the numerical values of the drill hole apportionment are slightly different, that is, the sizes of the first set value and the second set value which are correspondingly set are slightly different, but the difference is small. To further improve the drilling accuracy of the drilling mechanism, the control mechanism 400 further collects and calculates an average value of the first setting values of the plurality of plates as a first setting value of the type of plate, and collects and calculates an average value of the second setting values of the plurality of plates as a second setting value of the type of plate, so that the first setting value and the second setting value obtained by averaging are the expansion and contraction program of the type of plate. Like this, to same batch of plate of the same type, when dividing the board, first setting value and second setting value are the numerical value after a plurality of plates are average, have improved drilling mechanism's drilling precision and suitability greatly.
