Technical Field

[0001] The present application relates to the technical field of film stripping devices, and in particular to a film stripping spray pilot device. Background Art

[0002] In the production process of circuit boards, dry films or wet films are often used to protect the copper layers that do not need to be etched. However, these protective films are no longer needed after the etching process of the circuit board is completed. After that, the circuit board needs to be stripped.

[0003] At present, spray-type film stripping equipment is often used to strip the film on circuit boards. The spray-type film stripping equipment includes a box, a nozzle and a box cover. The circuit board is placed in the box, and after closing the box cover, the stripping liquid is evenly sprayed on the surface of the workpiece through the nozzle to achieve film stripping.

[0004] During the film removal process, the film removal liquid often seeps out from the gap between the box cover and the box body. The leakage of the film removal liquid may cause the operator to accidentally touch it, thereby causing the risk of skin injury to the operator. Summary of the Invention

[0005] In order to reduce the situation where the film stripping liquid penetrates through the gap between the box body and the box cover, the present application provides a film stripping spray pilot device.

[0006] This application provides a film stripping spray pilot device, which adopts the following technical solutions:

[0007] A film stripping spray pilot device includes a box body, a clamping plate group is provided in the box body, the clamping plate group is used to clamp the circuit board, a spray pipe is installed in the box body, the output end of the spray pipe is aligned with the circuit board, a mounting seat is fixed on one side of the box body, a connecting cavity is penetrated through the side wall of the mounting seat, a connecting groove is provided on the top surface of the mounting seat, and a mounting groove is provided on the bottom surface of the mounting seat. A box cover is provided on the side of the box body close to the mounting seat, the top of the box cover is inserted into the connecting groove, and the bottom of the box cover is inserted into the mounting groove. The two wide sides of the box cover are respectively abutted against the two sides of the inner wall of the mounting seat, and the box cover seals the connecting cavity.

[0008] By adopting the above technical solution, the clamping plate group clamps the circuit board, and then the film stripping liquid is sprayed out through the spray pipe, and the film stripping liquid is sprayed onto the surface of the circuit board to strip the film.

[0009] During the process of stripping the circuit board, the box cover seals the connecting cavity, thereby reducing the stripping liquid from spraying out of the box body. At the same time, the top of the box cover is located in the connecting groove, and the bottom of the box cover is located in the mounting groove, so that the mounting seat close to the box body will block the stripping liquid, thereby reducing the stripping liquid from seeping out of the gap between the box cover and the box body. When the stripping liquid is sprayed to the inner side of the box cover, the stripping liquid flows downward along the side wall of the box cover into the mounting groove, thereby further reducing the stripping liquid from seeping out of the box cover.

[0010] Preferably, a liquid storage tank is provided on one side of the box body, the liquid storage tank is located at the bottom of the box body, a return pipe is inserted into the bottom of the box body, and the output end of the return pipe is inserted into the top of one side of the liquid storage tank.

[0011] By adopting the above technical solution, under the action of the reflux pipe, the stripping liquid sprayed on the circuit board in the box can be discharged, and then the stripping liquid is transported to the liquid storage tank cavity, thereby reducing the accumulation of the stripping liquid in the box, and further reducing the stripping liquid from leaking from the gap between the box cover and the box body.

[0012] Preferably, a liquid extraction pipe is inserted into the bottom of one side of the liquid storage tank, and the other end of the liquid extraction pipe is connected to one end of the spray pipe.

[0013] By adopting the above technical solution, under the action of the liquid extraction pipe, the film stripping liquid in the liquid storage tank can enter the spray pipe through the liquid extraction pipe, and then be sprayed onto the surface of the circuit board through the output end of the spray pipe for film stripping. With the cooperation of the reflux pipe and the liquid extraction pipe, the film stripping liquid can be recycled, thereby reducing the waste of resources.

[0014] Preferably, a filter is installed in the liquid storage tank, and the filter is vertically arranged in the middle of the liquid storage tank. The filter separates the liquid storage tank cavity into a liquid storage cavity and a liquid extraction cavity. The reflux pipe is located in the liquid storage cavity, and the liquid extraction pipe is located in the liquid extraction cavity.

[0015] By adopting the above technical solution, after the stripping liquid strips the film from the surface of the circuit board, the stripping liquid flows into the box cavity, and then enters the liquid storage cavity of the liquid storage tank through the reflux pipe. After the stripping liquid in the liquid storage cavity is filtered through the filter net, the stripping liquid enters the liquid extraction cavity, which can reduce the presence of impurities in the stripping liquid in the liquid extraction cavity. After that, the liquid extraction pipe transports the stripping liquid in the liquid extraction cavity to the spray pipe.

[0016] Preferably, a drain pipe is inserted into the bottom of the liquid storage tank, and the drain pipe is located in the liquid storage cavity.

[0017] By adopting the above technical solution, under the action of the liquid drain pipe, when the film stripping liquid needs to be replaced, the film stripping liquid can be discharged through the liquid drain pipe.

[0019] By adopting the above technical solution, the horizontal plane of the inner end of the inner bottom surface of the mounting seat is lower than the horizontal plane of the outer end, so that the height of the inner side of the mounting groove is lower than the height of the outer side. Therefore, after the film stripping liquid drips into the mounting groove, it will flow back into the box body from the inner side of the mounting groove, thereby further reducing the situation of the film stripping liquid seeping out of the box cover.

[0020] Preferably, a mounting plate is fixed in the liquid storage box, and the mounting plate is located on a side of the filter screen close to the liquid extraction cavity, and a flow hole is opened through the side wall of the mounting plate.

[0021] By adopting the above technical solution, under the action of the mounting plate, the connection stability of the filter screen can be improved, and at the same time, the film stripping liquid can enter the liquid extraction cavity through the circulation hole.

[0022] Preferably, there are two spray pipes, which are distributed at the top and bottom of the box.

[0023] By adopting the above technical solution, the two spray pipes are distributed at the top and bottom of the box, so that the two spray pipes can spray the top and bottom surfaces of the circuit board at the same time, thereby improving the efficiency of circuit board film stripping.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The clamping plate assembly clamps the circuit board, and then the stripping liquid is sprayed through the spray pipe onto the surface of the circuit board to strip the film. During the stripping process, the box cover seals the connection cavity, thereby reducing the possibility of stripping liquid spraying out of the box body. At the same time, the top of the box cover is located in the connection groove, and the bottom of the box cover is located in the installation groove. The mounting seat close to the box body blocks the stripping liquid, thereby reducing the possibility of stripping liquid seeping out of the gap between the box cover and the box body.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a film stripping spray pilot device.

[0034] Reference Figure 1 and Figure 2 A film stripping spray pilot device includes a box body 1, a clamping assembly is provided on the inner wall of the box body 1, the clamping assembly includes a plywood group 2, the plywood group 2 includes two plywoods 21, one end of the plywood 21 is fixed to one side of the inner wall of the box body 1, the two plywoods 21 are distributed along the vertical direction of the inner wall of the box body 1, a gap is provided between the two plywoods 21, there are two plywood groups 2, the two plywood groups 2 are relatively distributed on both sides of the inside of the box body 1, and a placement space for the circuit board is left between the two plywood groups 2.

[0035] A spray pipe 3 is fixed to the side wall of the box 1. In the embodiment of the present application, there are two spray pipes 3, which are distributed at the top and bottom of the box 1. The two spray pipes 3 are aligned with the placement space, and the long sides of the spray pipes 3 are parallel to the long sides of the placement space. A nozzle 31 is provided on the side of the two spray pipes 3 close to the placement space, and the output end of the nozzle 31 is aligned with the placement space.

[0036] One end of the circuit board is inserted into the gap between the two clamps 21, and the two clamps 21 clamp one end of the circuit board. Correspondingly, the other end of the circuit board is inserted into the gap between the other two clamps 21. Under the action of the two clamping plate groups 2, the two ends of the circuit board are clamped and the circuit board is limited. After that, the film stripping liquid is sprayed out from the nozzle 31, spraying the top and bottom surfaces of the circuit board respectively, thereby realizing the film stripping of the circuit board.

[0037] Reference Figure 3A mounting seat 4 is fixed on one side of the box body 1, and a connecting cavity is formed through the side wall of the mounting seat 4, which is connected to the cavity of the box body 1. A connecting groove 41 is formed on the top surface of the inner part of the mounting seat 4, and the long side of the connecting groove 41 is parallel to the long side of the mounting seat 4. Correspondingly, a mounting groove 42 is formed on the bottom surface of the inner part of the mounting seat 4, and the long side of the mounting groove 42 is parallel to the long side of the mounting seat 4. A box cover 5 is provided on the side of the box body 1 close to the mounting seat 4, and the top of the box cover 5 is inserted into the connecting groove 41, and the bottom of the box cover 5 is inserted into the mounting groove 42. The two wide sides of the box cover 5 are respectively in contact with the two sides of the inner wall of the mounting seat 4, and the box cover 5 seals the connecting cavity, so that the inside of the box body 1 is a closed cavity.

[0038] The depth of the mounting groove 42 is less than the depth of the connecting groove 41. When the box cover 5 is being installed, the top of the box cover 5 is first inserted into the connecting groove 41, so that the top surface of the box cover 5 abuts against the inner top surface of the mounting seat 4, thereby facilitating the bottom of the box cover 5 to be extended into the mounting groove 42. Afterwards, the box cover 5 is loosened, so that the bottom surface of the box cover 5 abuts against the inner bottom surface of the mounting seat 4, thereby making the top surface of the box cover 5 away from the inner top surface of the mounting seat 4. The depth of the mounting groove 42 is less than the depth of the connecting groove 41. Therefore, the top of the box cover 5 is still located in the connecting groove 41, thereby reducing the situation where the top of the box cover 5 is separated from the mounting seat 4.

[0039] Reference Figure 3 The top of the box cover 5 is located in the connecting groove 41, and the bottom of the box cover 5 is located in the mounting groove 42, so that the side of the mounting seat 4 close to the box body 1 will block the film stripping liquid, thereby reducing the film stripping liquid from leaking out of the gap between the box cover 5 and the box body 1. When the film stripping liquid is sprayed onto the inner side of the box cover 5, the film stripping liquid flows downward along the side wall of the box cover 5 into the mounting groove 42. The horizontal plane of the inner end of the bottom surface of the mounting seat 4 is lower than the horizontal plane of the outer end, so that the height of the inner side of the mounting groove 42 is lower than that of the outer side. Therefore, after the film stripping liquid drips into the mounting groove 42, it will flow back into the box body 1 from the inner side of the mounting groove 42, thereby further reducing the film stripping liquid from leaking out of the box cover 5.

[0040] A water leakage hole is formed on one side of the mounting seat 4 close to the splint 21 , which is connected to the cavity of the box body 1 . At the same time, the water leakage hole is connected to the mounting groove 42 . Under the action of the water leakage hole, the film stripping liquid in the mounting groove 42 can flow into the cavity of the box body 1 through the water leakage hole.

[0041] The splint 21 is set slightly tilted, and the splint 21 gradually tilts upward toward the end close to the mounting seat 4, so that the height of the splint 21 close to the mounting seat 4 is higher than the height of the end away from the mounting seat 4. When the water sprayed from the nozzle 31 flows into the gap between the two splints 21, it can reduce the stripping liquid from flowing down to the end of the box cover 5, thereby reducing the stripping liquid from leaking out of the box cover 5.

[0042] Reference Figure 1 and Figure 4A liquid storage tank 6 is provided on one side of the box body 1. The liquid storage tank 6 is located at the bottom of the box body 1. A drain port is opened through the bottom surface of the box body 1. A return pipe 71 is provided at the bottom of the box body 1. The input end of the return pipe 71 is inserted into the drain port, and the output end of the return pipe 71 is inserted into the top of one side of the liquid storage tank 6. Under the action of the return pipe 71, the stripping liquid sprayed on the circuit board in the box body 1 can be discharged, and then the stripping liquid is transported to the volume cavity of the liquid storage tank 6.

[0043] A mounting plate 81 is fixed in the liquid storage tank 6, and the mounting plate 81 is vertically arranged in the middle of the liquid storage tank 6. The mounting plate 81 divides the liquid storage tank 6 into a liquid storage chamber 61 and a liquid extraction chamber 62. The output end of the reflux pipe 71 is located in the liquid storage chamber 61, so that the reflux pipe 71 discharges the film stripping liquid into the liquid storage chamber 61. A filter screen 82 is installed on the side of the mounting plate 81 close to the liquid storage chamber 61. A flow hole is opened through the side wall of the mounting plate 81, and there are multiple flow holes. The multiple flow holes are evenly arranged along the side wall of the mounting plate 81, so that the film stripping liquid in the liquid storage chamber 61 is filtered by the filter screen 82 and enters the liquid extraction chamber 62. Under the action of the mounting plate 81, the connection stability of the filter screen 82 can be improved, and at the same time, the film stripping liquid can enter the liquid extraction chamber 62 through the flow hole.

[0044] A liquid extraction pipe 72 is inserted into the bottom of one side of the liquid storage tank 6. The liquid extraction pipe 72 is located in the liquid extraction chamber 62. One end of the liquid extraction pipe 72 is connected to a booster pump 74. The output end of the booster pump 74 is connected to a connecting pipe 75. The output end of the connecting pipe 75 is connected to one end of the spray pipe 3. The film stripping liquid enters the liquid extraction chamber 62 after being filtered through the filter mesh 82. Then, the booster pump 74 is started to transport the film stripping liquid in the liquid extraction chamber 62 through the liquid extraction pipe 72 to the connecting pipe 75, and then enters the spray pipe 3 and is finally sprayed out through the nozzle 31.

[0045] A drain pipe 73 is inserted into the bottom of the liquid storage tank 6. The drain pipe 73 is located in the liquid storage cavity 61. A valve is provided at one end of the drain pipe 73 near the liquid storage tank 6. Under the action of the drain pipe 73, when the film stripping liquid needs to be replaced, the valve is opened to discharge the film stripping liquid through the drain pipe 73.

[0046] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
