Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of the cutting method of the present application, the method including:
s110: during cutting, when a cutting program of the cutting equipment runs to a first virtual zone bit arranged on a cutting path, the called cutting parameter is switched to be a first cutting parameter.
S120: and when the cutting program of the cutting equipment continues to run to a second virtual zone bit arranged on the cutting path, switching the called cutting parameter into a second cutting parameter, wherein the first virtual zone bit and the second virtual zone bit are respectively arranged at the start point coordinate and the end point coordinate of the first sub-cutting path in the cutting path.
The cutting method can be used for cutting the cutting path on the circuit board, and can also be used for cutting other products, such as plates and the like. For convenience of explanation, the following description will be made of a cutting method for cutting a cutting path on a circuit board.
Meanwhile, the cutting equipment in the application can adopt a laser process for cutting and also can adopt a mechanical process for cutting, and the application is not limited.
Specifically, when there are multiple sub-cutting paths of different types on the cutting path, the cutting device needs to run different cutting parameters to respectively cut the sub-cutting path, where the cutting speed, the cutting depth, and the like corresponding to the different cutting parameters are different. And the first virtual flag bit and the second virtual flag bit are respectively arranged at the start point coordinate and the end point coordinate of the first sub-cutting path, in the cutting process, when the cutting program of the cutting equipment runs to the first virtual zone bit, the cutting equipment indicates that the cutting equipment is about to cut the first sub-cutting path, at the moment, the cutting parameters run by the cutting equipment are switched to the first cutting parameters, i.e. having the cutting device cut a first sub-cutting path on the cutting path using the first cutting parameters, when the cutting program of the cutting equipment runs to the second virtual zone bit, the cutting equipment is about to finish cutting the first sub-cutting path, at the moment, the cutting equipment can not use the first cutting parameter to cut, therefore, the cutting parameters of the operation of the cutting equipment are switched to the second cutting parameters, so that the cutting equipment can cut the next sub-cutting path by using the second cutting parameters.
It can be seen from the above that, in this embodiment, the first virtual flag bit and the second virtual flag bit are respectively added at the start point coordinate and the end point coordinate corresponding to the first sub-cutting path in the cutting program, so that in the cutting process, when the cutting device runs to the junction of the sub-cutting path, the cutting device can automatically switch the cutting parameters, compared with the prior art, the manual switching by an operator is not needed, and the whole cutting process is a continuous process, and multiple times of alignment are not needed, so that the cutting efficiency can be improved, and the cutting accuracy can be ensured.
In the present embodiment, it is necessary to add a first virtual flag bit and a second virtual flag bit at the start point coordinate and the end point coordinate corresponding to the first sub-cutting path in the cutting program in advance before step S110.
The first virtual flag bit and the second virtual flag bit may be the same or different, when the first virtual flag bit and the second virtual flag bit are the same, if the cutting program runs to the virtual flag bit, the cutting parameter is switched, and when the first virtual flag bit and the second virtual flag bit are different, if the cutting program runs to the virtual flag bit, the cutting program may further identify the virtual flag bit, and then determine to call the corresponding cutting parameter according to the identified virtual flag bit.
In other embodiments, the first virtual flag bit may be added only at the start coordinate of the first sub-cutting path, but not at the end coordinate of the first sub-cutting path, and the time for the cutting device to cut the first sub-cutting path may also be stored in the cutting device in advance, at this time, in the cutting process, when the cutting device runs to the first virtual flag bit, the cutting device switches the called cutting parameter to the first cutting parameter, then the cutting time of the cutting device is counted, when the cutting time of the cutting device reaches the pre-stored cutting time, it indicates that the cutting device is about to complete cutting the first sub-cutting path, the cutting device switches the called cutting parameter to the second cutting parameter, that is, the premise that the cutting device switches the called cutting parameter to the second cutting parameter at this time is that the cutting program is not run to the second virtual flag bit, but the cutting time of the cutting device from the first virtual zone bit reaches the pre-stored cutting time.
In an application scenario, as shown in fig. 2, the cutting path 210 on the circuit board 200 includes a copper sub-path 211 and a copper-free sub-path 212, wherein the copper sub-path 211 corresponds to a first cutting parameter, the copper-free sub-path 212 corresponds to a second cutting parameter, and meanwhile, the first sub-cutting path is the copper sub-path 211.
Specifically, in the application scenario, when the cutting device is cutting the copper-laid sub-path 211 on the cutting path 210, the cutting device automatically invokes a first cutting parameter to perform cutting, and when the cutting device is cutting the copper-free sub-path 212, the cutting device automatically invokes a second cutting parameter to perform cutting. Meanwhile, before cutting, a first virtual flag bit and a second virtual flag bit are respectively added at the start point coordinate and the end point coordinate of the corresponding copper-paved sub-path 211 in the cutting program.
In this embodiment, in order to avoid an error in the cutting program executed by the cutting device, step S110 further includes: before cutting, the cutting equipment reads a cutting program; and if the first virtual zone bit and/or the second virtual zone bit exist in the cutting program, the cutting equipment sends out a prompt message.
Specifically, when a first virtual flag bit and/or a second virtual flag are read to exist in a cutting program, the cutting device can pop up a prompt message through a pop-up window, the prompt message is used for prompting an operator that a first sub-cutting path exists on a cutting path, and then the operator confirms whether the first sub-cutting path exists on the cutting path of the current processed product according to the prompt message, so that the phenomenon that the first sub-cutting path does not exist on the cutting path due to errors when the first flag bit and the second flag bit are set, but the first virtual flag bit and/or the second virtual flag bit occur when the program is read can be avoided.
In an application scenario, if an operator finds that the first sub-cutting path does not exist on the cutting path when confirming according to the prompt message, the cutting process of the cutting equipment can be manually stopped. In another application scenario, the cutting device may also automatically stop the cutting process, and at this time, the cutting method further includes: detecting whether a confirmation instruction of a user to the prompt message is received within a preset time of sending the prompt message; if a confirmation instruction of the user to the prompt message is received, the cutting equipment operates a cutting program to cut; and if the confirmation instruction of the user to the prompt message is not received, the cutting equipment does not cut.
Specifically, if the user does not confirm the prompt message within the preset time of sending the prompt message, the cutting device automatically judges that the cutting program has an error, and then does not operate the cutting program to cut, and if the user confirms the prompt message within the preset time, it indicates that the operator has confirmed that the cutting path has the first sub-cutting path, and then operates the cutting program to cut.
The preset time is set by a designer, and may be set to 1 minute, 2 minutes, or the like.
Meanwhile, in order to ensure that the cutting device is really about to cut the first sub-cutting path when the called cutting parameter is switched to the first cutting parameter, before the called cutting parameter is switched to the first cutting parameter, the method further includes:
a: and shooting a picture of the current cutting position on the cutting path.
B: and identifying the picture by adopting an image identification technology.
C: and if the first sub-cutting path exists in the picture, switching the called cutting parameter into the first cutting parameter.
Specifically, a picture of a current cutting position on a cutting path is shot, if a first sub-cutting path exists in the shot picture, it indicates that the cutting equipment is actually about to cut the first sub-cutting path, and then a called cutting parameter is switched to a first switching parameter, and if the first sub-cutting path does not exist in the shot picture, it indicates that an error occurs when the cutting equipment runs a cutting program, or an error exists in the cutting program itself, and then the cutting process can be stopped, or a prompt message is sent to prompt.
It can be understood that, when the first sub-cutting path exists in the picture, it is not necessarily guaranteed that the cutting device is about to cut the first sub-cutting path, and it may also be that the first sub-cutting path is already partially cut, so in order to further improve the accuracy of the determination, step C may specifically be to switch the called cutting parameter to the first cutting parameter if the end of the first sub-cutting path exists in the picture, that is, only when the end of the first sub-cutting path exists in the shot picture, switch the called cutting parameter to the first cutting parameter, and otherwise stop the cutting process.
Similarly, before switching the invoked cutting parameter to the second cutting parameter, in order to ensure that the cutting device is indeed about to complete the cutting of the first sub-cutting path, the cutting method further comprises: counting the time length from the running of a cutting program of the cutting equipment from the first virtual zone bit to the second virtual zone bit; and if the difference between the counted duration and the pre-stored duration meets the difference condition, switching the called cutting parameter into a second cutting parameter.
Specifically, the actual time length required for cutting the first sub-cutting path is calculated in advance and stored in the cutting device, if the difference between the time length from the first virtual zone bit to the second virtual zone bit of the cutting program and the actual time length stored in advance meets the difference condition, it is indicated that the cutting device is actually about to finish cutting the first sub-cutting path, and further the called cutting parameter is switched to the second cutting parameter, if the difference between the time length from the first virtual zone bit to the second virtual zone bit of the cutting program and the actual time length stored in advance does not meet the difference condition, it is indicated that the operation of the cutting program is wrong, that is, in the actual cutting process, the cutting device does not finish cutting the first sub-cutting path, or the cutting device finishes cutting the first sub-cutting path in advance, at this moment, the cutting device stops the cutting process, and sending out a prompt message to prompt the operator.
In other embodiments, before the called cutting parameter is switched to the second cutting parameter, in order to ensure that the cutting device is really about to complete the cutting of the first sub-cutting path, a method similar to the above-mentioned method of capturing images and performing image recognition may be adopted.
Specifically, before the called cutting parameter is switched to the second cutting parameter, a picture of a current cutting position on the cutting path is shot, the shot picture is identified by adopting an image identification technology, if a first sub-cutting path exists in the picture, or if the end part of the first sub-cutting path exists in the picture, the called cutting parameter is switched to the second cutting parameter, otherwise, the cutting process is stopped.
