[0062] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0063] It should be noted that when an element is referred to as being "electrically connected" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "electrically connected" to another element, it can be a contact connection, for example, a wire connection, or a non-contact connection, for example, a non-contact coupling.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0065] Some embodiments of the present application will be described in detail below with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0066] Please refer to Figures 1 to 3 , the present application provides a circuit board dismounting structure 100. The circuit board dismounting structure 100 is used to dismount the multi-layer circuit board on a lock plate 200 (see Figure 3 ) and automatically turn over the dismounted circuit board and fix it to other positions of the lock plate 200. In this embodiment, only the circuit board dismounting structure 100 is used to dismount the double-layer circuit board as an example.

[0067] In this embodiment, the double-layer circuit board includes a first circuit board 201 (see Figure 7 ) and a second circuit board (not shown in the figure). The first circuit board 201 and the second circuit board are connected together by soldering. The lock plate 200 is also provided with a receiving part 202 which matches the size and shape of the first circuit board 201. After the first circuit board 201 and the second circuit board are dismounted by the circuit board dismounting structure 100, the first circuit board 201 can be rotated by 180 degrees and fixedly arranged in the receiving part 202. In this way, the electronic elements between the first circuit board 201 and the second circuit board are exposed, thereby facilitating the performance of corresponding operations on the electronic elements, such as maintenance.

[0068] In the embodiment, the circuit board dismounting structure 100 comprises a housing 10, a slide rail 20, a dismounting module 30 and a turnover module 40.

[0069] The housing 10 is used for accommodating the slide rail 20, the dismounting module 30 and the turnover module 40. The dismounting module 30 is arranged above the slide rail 20. The turnover module 40 is connected to the slide rail 20. The lock plate 200 slides into one end of the slide rail 20, passes through the dismounting module 30 and the turnover module 40, and then slides out from the other end of the slide rail 20. The dismounting module 30 is used for dismounting the first circuit board 201 from the lock plate 200 and placing the first circuit board 201 on the turnover module 40. The turnover module 40 is used for overturning the first circuit board 201 and fixing the overturned first circuit board 201 into the accommodating portion 202 of the lock plate 200.

[0070] The housing 10 is in the structure of a cuboid box. A support plate 11 is arranged inside the housing 10 (see Figure 2 ). The periphery of the support plate 11 is connected to the inner wall of the housing 10, so that the housing 10 is divided into a first housing 12 and a second housing 13. The first housing 12 is used for accommodating and mounting the slide rail 20, the dismounting module 30 and the turnover module 40. The first housing 12 is provided with a pair of opposite doors 121 on one side. The dismounting module 30 and the turnover module 40 can be mounted or repaired through the pair of opposite doors 121.

[0071] In the embodiment, the first housing 12 is provided with an opening, i.e. an inlet 122 and an outlet 123, adjacent to the two sides of the pair of opposite doors 121. The slide rail 20 is fixedly mounted in the first housing 12 and can extend out from the inlet 122 and the outlet 123.

[0072] It can be understood that the lock plate 200 can slide into the inlet 122 and slide to the dismounting module 30 through the slide rail 20, so that the dismounting module 30 dismounts the lock plate 200 and places the first circuit board 201 on the turnover module 40. Then the lock plate 200 slides to the position corresponding to the turnover module 40, so that the turnover module 40 fixes the overturned first circuit board 201 into the accommodating portion 202 of the lock plate 200. Finally, the lock plate 200 flows out from the outlet 123.

[0073] It can be understood that in the embodiment, the outer side of the first housing 12 can be further provided with control members such as an emergency stop button, a running indicator, an automatic and manual switching knob, a reset button, a start button and a power switch key, and the functions of the control members will not be described herein.

[0074] In the embodiment, a motor (not shown) and a heat dissipation member are installed in the second housing 13. The motor connects the slide rail 20 and the motor together via a motor, which drives the lock plate 200 to slide on the slide rail 20. The heat dissipation member is a fan, which is used to dissipate heat of the circuit board dismounting structure 100. It can be understood that in the embodiment, one part of the motor is arranged in the slide rail 20, and the other part of the motor is connected with the motor. The lock plate 200 can be arranged on the surface of the motor. Under the driving of the motor, the motor in the slide rail 20 slides, thereby driving the lock plate 200 on the motor to slide.

[0075] Please refer to Figure 4 In the embodiment, the slide rail 20 includes two guide rails 21. The guide rails 21 are substantially in the shape of a long strip. The guide rails 21 are formed with a sliding groove 211. The two guide rails 21 are oppositely arranged and correspond to two ends of the lock plate 200 respectively, so that the two sides of the lock plate 200 can be slidably connected on the sliding groove 211.

[0076] In the embodiment, the slide rail 20 further includes a support part 22. One end of the support part 22 is perpendicularly arranged on the support plate 11, and the other end is connected to the guide rail 21 to support the guide rail 21.

[0077] Please refer to Figure 5 The dismounting module 30 is arranged on the support plate 11 and above the slide rail 20. The dismounting module 30 includes a mounting part 31, a lead screw 32, a cylinder 33 and a dismounting structure 34. The mounting part 31 is used to mount the dismounting module 30 on the support plate 11. The lead screw 32 is arranged on the mounting part 31. The cylinder 33 is fixedly connected to the lead screw 32. The dismounting structure 34 is connected to the cylinder 33. The dismounting structure 34 is used to dismount the first circuit board 201 from the lock plate 200.

[0078] The mounting part 31 is perpendicularly arranged. One end of the mounting part 31 crosses the slide rail 20 and is fixedly connected with the support plate 11. One side of the mounting part 31 is mounted on the lead screw 32. It can be understood that the lock plate 200 can pass below the mounting part 31.

[0079] The lead screw 32 is substantially in the shape of a strip. One side of the lead screw 32 is arranged on one side of the mounting part 31 and can slide relative to the mounting part 31. The other side of the lead screw 32 is fixedly connected to the cylinder 33. Specifically, the lead screw 32 is connected with a motor (not shown) to move relative to the mounting part 31 in a first direction, for example, Y-axis direction, under the driving of the motor.

[0080] The air cylinder 33 is vertically arranged. One side of the air cylinder 33 is fixedly connected to the side of the lead screw 32 away from the mounting portion 31. The other side of the air cylinder 33 is fixedly connected to the disassembling structure 34. Specifically, in this embodiment, the air cylinder 33 is used to drive the disassembling structure 34 to move in a second direction, for example, the Z-axis direction.

[0081] It can be understood that, in this embodiment, through the movement of the lead screw 32 and the air cylinder 33, the disassembling structure 34 is driven to move, so as to adjust the position of the disassembling structure 34 to be close to the lock plate 200 or the turnover module 40.

[0082] The disassembling structure 34 is a tubular structure in the shape of a "7". In this embodiment, the disassembling structure 34 is a blow nozzle.

[0083] Further, the disassembling structure 34 is arranged close to the lock plate 200, and melts the tin between the first circuit board 201 and the second circuit board by heating, so as to disassemble the first circuit board 201. The disassembling structure 34 is also used to adsorb the first circuit board 201 and place it on the turnover module 40.

[0084] In this embodiment, the disassembling module 30 further comprises an inductor 35. The inductor 35 is arranged on one side of the mounting portion 31. The inductor 35 is used to sense the position of the lock plate 200. When it is sensed that the lock plate 200 is close to the disassembling module 30, the disassembling module 30 is ready to disassemble and adsorb the first circuit board 201.

[0085] Please refer to Figure 6 , the turnover module 40 comprises a sliding portion 41, a connecting portion 42, a first adjusting air cylinder 43, a rotating air cylinder 44, and a transposing carrier 45. The sliding portion 41 is fixedly connected to the sliding rail 20. The connecting portion 42 is arranged on the sliding portion 41. The first adjusting air cylinder 43 is fixedly connected to the connecting portion 42. The first adjusting air cylinder 43 is used to adjust the position of the transposing carrier 45. The rotating air cylinder 44 is arranged on the first adjusting air cylinder 43. The transposing carrier 45 is arranged on the rotating air cylinder 44, and the transposing carrier 45 is used to place the first circuit board 201 adsorbed by the disassembling structure 34. The rotating air cylinder 44 is used to rotate the first circuit board 201 by 180 degrees. Through the turnover module 40, the disassembled first circuit board 201 is turned over by 180 degrees and then fixedly placed in the receiving portion 202 of the lock plate 200. In this way, the electronic elements between the double-layer circuit boards are exposed, so as to facilitate subsequent operations.

[0086] Specifically, the sliding part 41 is substantially in a strip shape. One side of the sliding part 41 is fixed on the slide rail 20. The other side of the sliding part 41 is provided on the connecting part 42. It can be understood that in the present embodiment, one side of the sliding part 41 is fixed on the slide rail 20, so that the turnover module 40 is connected to the slide rail 20.

[0087] The connecting part 42 is substantially in an "L" shaped plate structure. One side of the connecting part 42 is provided on the sliding part 41 and slides relative to the sliding part 41, and the other side of the connecting part 42 is fixedly connected to the first adjusting cylinder 43. Specifically, the connecting part 42 comprises an X-axis connecting plate and a Y-axis connecting plate, the X-axis connecting plate is slidingly provided on the sliding part 41, and the Y-axis connecting plate is fixedly connected to the first adjusting cylinder 43.

[0088] The first adjusting cylinder 43 is substantially in a plate structure. The first adjusting cylinder 43 is vertically connected to the connecting part 42. One side of the first adjusting cylinder 43 is connected to the rotating cylinder 44 and the transfer carrier 45. The other side of the first adjusting cylinder 43 is fixedly connected to the connecting part 42.

[0089] Specifically, in the present embodiment, the first adjusting cylinder 43 is used to drive the rotating cylinder 44 and the transfer carrier 45 to move in a second direction, for example, the Z-axis direction. It can be understood that after the turnover module 40 turns the first circuit board 201 by 180 degrees and fixes it to the lock plate 200, the first adjusting cylinder 43 moves in the second direction, for example, away from the slide rail 20, so that the lock plate 200 can pass through the turnover module 40 and slide out of the other end of the slide rail 20.

[0090] The rotating cylinder 44 is substantially in a cuboid shape. The rotating cylinder 44 is placed along the Y-axis. One side of the rotating cylinder 44 is connected to the side of the first adjusting cylinder 43 away from the connecting part 42. The other side of the rotating cylinder 44 is connected to the transfer carrier 45. The rotating cylinder 44 rotates clockwise or counterclockwise, thereby driving the transfer carrier 45 to turn over. In the present embodiment, the rotating cylinder 44 drives the transfer carrier 45 to turn over by 180 degrees.

[0091] Please refer to Figure 7 , the transfer carrier 45 is substantially in a plate shape. The transfer carrier 45 is used to place the first circuit board 201. Specifically, the transfer carrier 45 comprises a rotating bracket 451, a placing plate 452 and a pushing module 453 (see Figure 8 ).

[0092] The rotating support 451 is bent at one end and the bent part is connected to the rotating cylinder 44 and can rotate relative to the rotating cylinder 44. The other end of the rotating support 451 is fixedly connected to the placing plate 452. The rotating support 451 further forms a gap.

[0093] The placing plate 452 is generally plate-shaped and a receiving cavity (not shown in the figure) matching the shape and size of the first circuit board 201 is formed in the middle position of the placing plate 452. The receiving cavity is used to accommodate and place the first circuit board 201.

[0094] In this embodiment, at least one guide column 4521 is further arranged around the receiving cavity of the placing plate 452. The disassembling structure 34 can be accurately placed in the receiving cavity along the guide column 4521. In this embodiment, there are three guide columns 4521. In this embodiment, at least one wedge-shaped push block 4522 is further arranged around the receiving cavity of the placing plate 452. In this embodiment, there are three wedge-shaped push blocks 4522.

[0095] In this embodiment, the three guide columns 4521 ensure the cooperation accuracy of the first circuit board 201 and the transposition carrier 45. In this embodiment, the accuracy tolerance can be + / - 0.05 mm.

[0096] The pushing module 453 is arranged in the gap of the rotating support 451. The pushing module 453 is used to push the first circuit board 201 to be limitingly fixed in the receiving part 202 of the lock plate 200 after the first circuit board 201 is turned over.

[0097] In this embodiment, at least one positioning pin 4523 is further arranged in the receiving cavity of the placing plate 452. The positioning pin 4523 is used to ensure the placement accuracy of the first circuit board 201. In this embodiment, the maximum deviation allowed by the first circuit board 201 is 1.0 mm, which ensures the cooperation accuracy of the disassembling module 30 and the transposition carrier 45 when the first circuit board 201 is placed.

[0098] Please refer to Figure 8 , the rotating support 451 is further provided with a vacuum interface 4511. The vacuum interface 4511 is used to adsorb and fix the first circuit board 201 after the first circuit board 201 is placed on the placing plate 452, so as to avoid the first circuit board 201 from being separated from the placing plate 452 during rotation. It can be understood that when the first circuit board 201 is limitingly fixed after being rotated, the vacuum interface 4511 is in an open state and no longer adsorbs and fixes the first circuit board 201.

[0099] Please refer to Figure 6In the embodiment, the turnover module 40 further comprises a second adjusting cylinder 46. The second adjusting cylinder 46 is arranged on the slide rail 20 and connected to the connecting part 42 away from the first adjusting cylinder 43. Specifically, the second adjusting cylinder 46 is used to drive the connecting part 42 to move relative to the sliding part 41 along a third direction, for example, the X-axis direction.

[0100] The second adjusting cylinder 46 can drive the turnover module 40 to move relative to the second sliding part 41.

[0101] Specifically, when the turnover module 40 is installed, the turnover module 40 has a certain distance from the disassembly module 30. When the disassembly structure 34 disassembles the first circuit board 201 and adsorbs it, the second adjusting cylinder 46 drives the turnover module 40 to slide along the sliding part 41, so that the transfer carrier 45 moves to the opposite position of the disassembly structure adsorbing the first circuit board 201. In this way, the disassembly module 30 working avoids interference or adverse effects on the turnover module 40.

[0102] Please refer again to Figure 3 In the embodiment, at least one sliding block 210 is arranged around the accommodation part 202. The sliding block 210 matches the position of the wedge-shaped push block 4522 on the placement plate 452. When the first circuit board 201 is rotated by 180 degrees, the vacuum interface 4511 is opened, and the pushing module 453 pushes the first circuit board 201 to approach the accommodation part 202. When the wedge-shaped push block 4522 contacts the sliding block 210, the wedge-shaped push block 4522 pushes the sliding block 210 to move away from the accommodation part 202, until the first circuit board 201 is fixed in the accommodation part 202. Then, the first adjusting cylinder 43 moves away from the lock plate 200 along the second direction, and the lock plate 200 fixing the first circuit board 201 passes through the turnover module 40 and slides out of the outlet 123 of the shell 10.

[0103] Specifically, in the embodiment, the sliding block 210 also has a holding function. When the first circuit board 201 is fixed in the accommodation part 202, the sliding block 210 can abut against the first circuit board 201, avoiding the first circuit board 201 from being separated from the lock plate 200 during sliding.

[0104] It can be understood that when the lock plate 200 to be disassembled enters from the entrance 122 of the shell 10 and slides along the slide rail 20 to the disassembly module 30. First, the disassembly module 30 disassembles the first circuit board 201 and absorbs it. Then, the second adjusting cylinder 46 drives the turnover module 40 to move to be arranged in the opposite position of the disassembly structure 34. Then, the disassembly module 30 places the first circuit board 201 on the placement plate 452. The transfer carrier 45 rotates 180 degrees. Finally, the first circuit board 201 is fixed to the receiving portion 202 of the lock plate 200. At this time, the first adjusting cylinder 43 slides in the third direction, the lock plate 200 passes through the turnover module 40 and slides out of the outlet 123 of the shell 10.

[0105] In this way, the electronic elements between the first circuit board 201 and the second circuit board are exposed, and other steps can be performed on the electronic elements.

[0106] In the embodiment, the circuit board dismounting structure 100 can dismount the first circuit board 201 from the lock plate 200 and automatically fix the first circuit board 201 at the receiving portion 202 of the lock plate 200 after turning over. The electronic elements between the double-layer circuit boards are exposed, so that the electronic elements can be repaired. The circuit board dismounting structure 100 has low cost and high production efficiency.

[0107] The above embodiments are only used to illustrate the technical solutions of the present application and not limit the present application. Although the present application is described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application. Those skilled in the art can also make other changes in the design of the present application within the spirit of the present application, as long as they do not deviate from the technical effects of the present application. These changes made in the spirit of the present application should be included in the scope of the present application.
