[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] <System Embodiment> Figure 1 1 is a schematic diagram of the composition structure of an operating system that can be used to control etching and tin stripping equipment to process materials according to an embodiment. Figure 1 As shown, the operating system for controlling the etching tin stripping equipment to process materials may include an etching tin stripping equipment 10, a controller 20 and an image acquisition device 30. The controller 20 is respectively communicated with the etching tin stripping equipment 10 and the image acquisition device 30. The image acquisition device 30 is used to collect image information about the material before the material enters the etching tin stripping equipment 10. The etching tin stripping equipment 10 is equipped with an etching liquid pipeline and a tin stripping liquid pipeline. The etching liquid pipeline is used to spray etching liquid on multiple etching areas, and the tin stripping liquid pipeline is used to spray tin stripping liquid on multiple tin stripping areas.

[0027] In this application, if Figure 1 As shown, the operating system for controlling the etching and tin stripping equipment 10 to process materials may include multiple first conveying wheels 6 and second conveying wheels 7. The first conveying wheels 6 can drive the circuit board 5 to move into the interior of the etching and tin stripping equipment 10, and the second conveying wheels 7 can drive the circuit board 5 after the tin stripping is completed to move out of the etching and tin stripping equipment 10.

[0028] In this application, if Figure 2As shown, multiple first conveying wheels 6 can be arranged in two rows, so that the circuit board 5 can be sent to the etching and tin stripping equipment 10 from between the two rows of first conveying wheels 6, and multiple second conveying wheels 7 can be arranged in two rows, so that the circuit board 5 after tin stripping can be sent out of the etching and tin stripping equipment 10 from between the two rows of second conveying wheels 7.

[0029] In the present application, the etching and tin stripping device 10 can be divided into an etching part 11 and a tin stripping part 12. The etching part 11 is provided with two rows of third conveying wheels 112, so that the circuit board 5 can be moved to the tin stripping part 12 driven by the third conveying wheels 112. An etching liquid pipeline is also provided inside the etching part 11. The etching liquid pipeline is provided with a plurality of etching liquid nozzles 111, and these etching liquid nozzles 111 can spray etching liquid toward the circuit board 5. The tin stripping part 12 is provided with two rows of fourth conveying wheels 122, so that the circuit board 5 can be moved out of the etching and tin stripping device 10 driven by the fourth conveying wheels 122. A tin stripping liquid pipeline is also provided inside the tin stripping part 12. The tin stripping liquid pipeline is provided with a plurality of tin stripping liquid nozzles 121, and these tin stripping liquid nozzles 121 can spray tin stripping liquid toward the circuit board 5.

[0030] In this application, if Figure 3 As shown, each etching liquid nozzle 111 can spray an etching area. For example, the etching liquid nozzle 111 located above the etching part 11 can spray the etching area A1-etching area C3, and the etching liquid nozzle 111 located below the etching part 11 can spray the etching area E4-etching area G6. For another example, the etching area A1 can correspond to the etching area E4.

[0031] In this application, if Figure 3 As shown, each tin stripping liquid nozzle 121 can spray a tin stripping area. For example, the tin stripping liquid nozzle 121 located above the tin stripping portion 12 can spray the tin stripping area H1-tin stripping area J3, and the tin stripping liquid nozzle 121 located below the tin stripping portion 12 can spray the tin stripping area K4-tin stripping area P6. For another example, the tin stripping area I2 can correspond to the tin stripping area Q5.

[0032] In the present application, the image acquisition device 30 is, for example, a camera, which can be arranged above the first conveying wheel 6 so that the camera can acquire an image of the K1 area, that is, collect image information about the material.

[0033] The controller 20 is configured to: receive target image information about the target material output by the image acquisition device 30; determine a target material model that matches the target material in the target image information through a preset image library; determine the position information of the target material according to the correspondence between the material characteristics of the target material model and the target material in the target image information; and according to the position information and the material characteristics, first control the etching liquid pipeline to spray the etching liquid on the first etching area, and then control the tin stripping liquid pipeline to spray the tin stripping liquid on the first etching area.

[0034] The material may be a circuit board, and the target material may be a circuit board.

[0035] In the present application, the controller 20 can pre-set an image library, and the user can import the circuit layout diagrams of each circuit board 5 into the controller 20, so that the image library can store the circuit layout diagrams of multiple circuit boards 5, that is, multiple material models.

[0036] In the present application, the target image information can display material features such as component mounting holes and connecting lines of the target material, that is, the target material model matched by the target material has the same number, size and position of component mounting holes and connecting lines of the target material.

[0037] In the present application, since the shooting position of the image acquisition device 30 is fixed, the controller 20 pre-sets the position of the image output by the image acquisition device 30 relative to the etching and tin stripping device 10. For example, Figure 1 As shown, the K1 area can reflect the image output by the image acquisition device 30, the circuit board 5 can be matched with a material model, and it can be determined that the long side of the circuit board 5 deviates from the forward direction of the circuit board 5 by a certain angle, and the circuit board 5 can pass through the etching area A1 to the etching area B3, the etching area E4 to the etching area F6, and the desoldering area K4 to the etching area O6.

[0038] In this embodiment, by identifying the material model corresponding to the target material from the image library and combining the location information and material characteristics of the target material, the etching liquid pipeline and the tin stripping liquid pipeline can be effectively controlled to process the target material in a targeted manner. There is no need for the etching and tin stripping equipment to increase the scale of spraying or increase the intensity of spraying, which effectively reduces the consumption of etching liquid and tin stripping liquid, improves the working efficiency of the etching and tin stripping equipment, and thus reduces the processing cost of the circuit board.

[0039] In some embodiments, in order to further improve the utilization efficiency of etching liquid and tin stripping liquid, the controller 20 is also configured to: determine the second etching area and the second tin stripping area through which the target material passes among multiple etching areas and multiple tin stripping areas according to the lateral interval and the longitudinal interval of the target material reflected by the position information; and screen out the first etching area and the first tin stripping area from the second etching area and the second tin stripping area according to the processing area of ​​the target material in the second etching area and the second tin stripping area reflected by the material characteristics.

[0040] In the present application, the transverse interval is the transverse length of the target material model, and the longitudinal interval is the length of the target material model in the forward direction.

[0041] In some examples, taking the side of the target material facing upward as an example, the controller 20 can determine the processing area of ​​the target circuit board 5 from etching area A1 to etching area A3, and the processing area from etching area B1 to etching area B3, that is, the processing area of ​​the second etching area, according to the lateral interval and longitudinal interval of the target material model. Among them, etching area A1 to etching area B3 is the second etching area, and tin stripping area H1 to tin stripping area J3 is the second tin stripping area. Within the first area range of the processing area, the controller 20 can control the etching liquid pipeline to spray etching area A1 to etching area A3, that is, the first etching area is etching area A1 to etching area A3. Within the second area range, the controller 20 can control the etching liquid pipeline to spray etching area A2 and etching area A3, that is, the first etching area is etching area A2 and etching area A3. Within the third area range, the controller 20 can control the etching liquid pipeline to spray etching area A3, that is, the first etching area is etching area A3. Among them, the first area range, the second area range and the third area range can be set artificially, and are not limited here.

[0042] In some examples, taking the calculation of the processing area as an example, the calculation is performed by using the pre-set dividing line G1 and dividing line G2. When the area to be etched of the target material model is known, the processing area of ​​the target material in the etching area A1 to the etching area A3 can be determined according to the dividing line G1, and the processing area of ​​the target material in the etching area B1 to the etching area B3 can be determined according to the dividing line G1 and the dividing line G2. Calculating the area to be etched and the area divided by the dividing line is a prior art and is not limited here.

[0043] In some embodiments, in order to further improve the utilization efficiency of etching solution and tin stripping solution, the system also includes a posture adjustment device 40, which is communicatively connected to the controller 20, and the posture adjustment device 40 is used to adjust the material posture to achieve parallelism between the material and the forward direction of the material.

[0044] In this application, if Figure 1 As shown, the posture adjustment device 40 may include a first telescopic portion 41 and a second telescopic portion 42, the thickness of the first telescopic portion 41 and the second telescopic portion 42 is smaller than the gap between the upper conveying wheel and the lower conveying wheel, the first telescopic portion 41 and the second telescopic portion 42 can clamp the circuit board 5 so that the circuit board 5 can be parallel to the forward direction of the circuit board 5, that is, the posture of the circuit board 5 can be adjusted, and the first telescopic portion 41 and the second telescopic portion 42 can clamp the circuit board 5 and move to adjust the position of the circuit board 5.

[0045] The controller 20 is also configured to: control the posture adjustment device 40 to adjust the posture of the target material so that the target material is parallel to the forward direction of the material; when receiving the reaction force signal fed back by the posture adjustment device 40, obtain the position parameter information of the posture adjustment device 40; according to the position parameter information, control the posture adjustment device 40 to move the target material to a set position; wherein the set position is related to the edge of the etching and tin stripping equipment 10.

[0046] In the present application, the controller 20 can detect the driving voltage of the posture adjustment device 40. When the driving voltage of the posture adjustment device 40 increases abnormally, it can be determined that the posture adjustment device 40 is subjected to a reaction force, that is, the posture adjustment device 40 feeds back a reaction force signal. The controller 20 can determine the two horizontal edge lines of the target material according to the positions of the first telescopic part 41 and the second telescopic part 42, and use the posture adjustment device 40 to move the target material to a set position. For example, the controller 20 can control the positions of the first telescopic part 41 and the second telescopic part 42 to control the edge line B3 of the target material to be collinear with the edge line B1, or control the edge line B4 of the target material to be collinear with the edge line B2; wherein the horizontal direction is perpendicular to the forward direction of the target material.

[0047] In some embodiments, in order to control the spraying of different etching areas, the etching liquid pipeline is equipped with a plurality of etching liquid valves, and the etching liquid valves are used to control the corresponding etching areas to spray the etching liquid; the tin stripping liquid pipeline is equipped with a plurality of tin stripping liquid valves, and the tin stripping liquid valves are used to control the corresponding tin stripping areas to spray the tin stripping liquid; The controller 20 is also configured to: first control the etching liquid valve of the first etching area to open according to the position information and material characteristics, so as to control the first etching area to spray the etching liquid, and then control the tin stripping liquid valve of the first tin stripping area to open, so as to control the first tin stripping area to spray the tin stripping liquid.

[0048] In some examples, taking the case where part of the target material passes through etching area A1 to etching area A3 as an example, the area of ​​this part is the above-mentioned processing area. When the processing area is within the first area range, the controller 20 can control the etching liquid valve of etching area A1 to etching area A3 to open, that is, the first etching area is etching area A1 to etching area A3. Within the second area range, the controller 20 can control the etching liquid valve of etching area A2 and etching area A3 to open, that is, the first etching area is etching area A2 and etching area A3. Within the third area range, the controller 20 can control the etching liquid valve of etching area A3 to open, that is, the first etching area is etching area A3.

[0049] As used in the embodiments of the present disclosure, the memory of the controller 20 is used to store a computer program, which is used to control the processor of the controller 20 to operate according to the method for controlling the etching and tin stripping equipment to process materials according to any embodiment. A technician can design a computer program according to the scheme of the embodiments of the present disclosure. How the computer program controls the processor to operate is well known in the art, so it will not be described in detail here.

[0050] <Method Example> Figure 4 The present invention is a flow chart of a method for controlling the operation of an etching and tin stripping device for processing materials according to an embodiment. The implementation subject is a controller.

[0051] like Figure 4 As shown, the method for controlling the operation of the etching and tin stripping equipment to process materials in this embodiment may include the following steps S410 to S440: Step S410: receiving target image information about a target material output by an image acquisition device.

[0052] In some embodiments, before step S410, steps S310 to S330 are also included: Step S310, controlling the posture adjustment device to adjust the posture of the target material so that the target material is parallel to the forward direction of the material.

[0053] Step S320, when receiving the reaction force signal fed back by the posture adjustment device, obtaining the position parameter information of the posture adjustment device.

[0054] Step S330, according to the position parameter information, control the posture adjustment device to move the target material to a set position; wherein the set position is related to the edge of the etching and tin stripping equipment.

[0055] Step S420: determining a target material model that matches the target material in the target image information through a preset image library.

[0056] In some embodiments, step S420 may include the following steps S4201 to S4204: Step S4201, determining a first region in the target image information that conforms to a first set shape and a first position of the first region.

[0057] In the present application, the first set shape may be a circle, that is, the controller may determine the first area representing the component mounting hole in the target material and the first position of the first area in the target image information.

[0058] Step S4202: Filter out matching target material models from a preset image library according to the number of first regions and the first positions.

[0059] In the present application, the controller can filter out target material models having component mounting holes in the same position and the same number of component mounting holes in the image library.

[0060] Step S4203: when the target material model is associated with the front and back distinguishing mark, determine a second area in the target image information that conforms to the second set shape and a second position of the second area.

[0061] Step S4204: determining, based on the number and the second position of the second area, that the first side of the target material displayed in the target image information corresponds to the second side of the target material model.

[0062] In some examples, the target material model is associated with a front and back distinguishing mark, which may include a specific position and a specific shape of a specific area of ​​the target material model on the front or back, for example, the target material model has a square at the center of the front. When the second area that conforms to the square in the target image information is one and is at the center, it can be determined that the first side of the target material displayed in the target image information corresponds to the front side of the target material model, that is, the second side. When the second area that conforms to the square in the target image information is not equal to one and / or is at the center, it can be determined that the first side of the target material displayed in the target image information corresponds to the back side of the target material model.

[0063] In other words, by distinguishing the front and back sides, it can adapt to circuit boards with different etching and desoldering standards, further improving the utilization efficiency of etching liquid and desoldering liquid.

[0064] Step S430, determining the location information of the target material according to the correspondence between the material characteristics of the target material model and the target material in the target image information.

[0065] Step S440, according to the position information and the material characteristics, first control the etching liquid pipeline to spray the etching liquid on the first etching area, and then control the tin stripping liquid pipeline to spray the tin stripping liquid on the first etching area.

[0066] In some embodiments, step S440 may include the following step S4401: Step S4401, according to the position information and material characteristics, first control the etching liquid valve of the first etching area to open, so as to control the first etching area to spray the etching liquid, and then control the tin stripping liquid valve of the first tin stripping area to open, so as to control the first tin stripping area to spray the tin stripping liquid.
