Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a suction machine for PCB processing. Background Technology

[0002] PCB manufacturing involves etching, drilling, and soldering an insulating substrate and conductive copper foil to create an electronic component carrier with a specific circuit pattern. It is the core link in enabling electrical connections in electronic products. The process covers steps from cutting the original board material and transferring the circuit pattern to coating the solder mask and surface treatment. It is necessary to balance precision and reliability to adapt to the needs of different electronic devices.

[0003] PCB board processing first involves pre-processing such as cutting and drilling to form a substrate. Then, a suction cup machine precisely picks up the substrate using suction cups and transfers it to processes such as lamination and exposure. The suction cup machine achieves stable transfer of the substrate between various processing stages by using negative pressure adsorption and automated movement, reducing damage caused by manual contact.

[0004] In a PCB manufacturing line, a suction machine is used to pick up PCBs one by one from stacks of PCBs and move them to the next process. However, each time a PCB is picked up, the descent depth needs to be adjusted to make contact with the PCB. If the descent is too deep, it will cause compression to the remaining PCBs.

[0005] Therefore, a suction plate machine for PCB processing is proposed to address the above problems. Utility Model Content

By adding gears and toothed plates, each time the PCB moves on the push plate, the next PCB is moved to the position of the previous PCB, making it faster when picked up by the suction plate. Simultaneously, the engagement of the gears and toothed plates is more accurate, reducing misalignment during movement and increasing the accuracy of contact between the PCB and the suction plate. This accelerates the speed at which the PCB is picked up by the suction plate.

[0010] Preferably, a connecting pipe is fixed to the side wall of the stacking box; a nozzle is connected to the end of the connecting pipe; the nozzle is located at the connection between the gear and the toothed plate; by adding a nozzle, the connection between the gear and the toothed plate can be lubricated, thereby increasing its maintenance and extending its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a suction plate machine for PCB processing includes a worktable 1, a support frame 11 fixedly connected to the top of the worktable 1; a cylinder 12 fixedly connected to the top of the support frame 11; a suction plate 13 fixedly connected to the output end of the cylinder 12; a stacking box 14 fixedly connected to the middle of the worktable 1; a feeding assembly 15 provided on the side wall of the stacking box 14; a servo motor 16 fixedly connected to the surface of the stacking box 14; a gear 17 fixedly connected to the output end of the servo motor 16; the gear 17 is mounted on the stacking box. The stacking box 14 is rotatably connected; a toothed plate 18 is slidably connected inside the stacking box 14; the gear 17 and the toothed plate 18 are correspondingly arranged and in transmission engagement; a push plate 19 is fixedly connected to the top of the toothed plate 18; the push plate 19 is slidably connected to the stacking box 14; during operation, before use, the stacking box 14 is opened by the feeding assembly 15, and then the PCB board is placed on top of the push plate 19 for stacking. After placement, the stacking box 14 is closed by the feeding assembly 15, and then the suction plate 13 is... A negative pressure is generated by connecting an air pump through a pipe, and then the cylinder 12 is activated to move the suction plate 13 downwards towards the PCB board for suction. After a PCB board is suctioned out of the stacking box 14, the servo motor 16 is activated to send the next PCB board to the position of the previous PCB board through the precise transmission between the gear 17 and the toothed plate 18. Thus, when the suction plate 13 suctions again, it descends to the same depth as before to contact the PCB board. This ensures that the suction is performed at the same height each time, thereby reducing the time required to adjust the suction plate 13. By adding gears 17 and toothed plates 18, the next PCB board can be moved to the position of the previous PCB board each time it moves on the push plate 19, making it faster when it is suctioned by the suction plate 13. At the same time, the engagement of gears 17 and toothed plates 18 is more accurate, reducing misalignment during movement and increasing the accuracy of contact between the PCB board and the suction plate 13. This speeds up the suction of the PCB board by the suction plate 13.

[0026] like Figures 1 to 4 As shown, the feeding assembly 15 includes a square plate 2; the square plate 2 is rotatably connected to the stacking box 14; both the square plate 2 and the side wall of the stacking box 14 are provided with a pair of pin holes 21; during operation, when feeding the inside of the stacking box 14, the pin inside the pin hole 21 is first pulled out, and then the square plate 2 is rotated to open the stacking box 14. After opening, the PCB board can be filled into the inside of the stacking box 14 from the side; by adding the square plate 2 and the pin holes 21, the PCB board can be quickly placed from the side when feeding the PCB board, thereby speeding up the stacking of the PCB board and increasing the convenience of feeding.

[0027] like Figures 3 to 5As shown, multiple damping spring dampers 3 are fixedly connected to the end of the workbench 1; a baffle 31 is fixedly connected to the end of each damping spring damper 3; the baffle 31 and the square plate 2 are correspondingly arranged; during operation, after the square plate 2 is opened, it will rotate and then gradually approach the workbench 1. At this time, it will first contact the baffle 31, and then the baffle 31 will receive the force after the square plate 2 rotates. When it contacts the baffle 31, the damping spring damper 3 will be compressed, and during the compression, the rotation speed of the square plate 2 will be gradually reduced, causing it to gradually stop rotating, thereby intercepting the impact between the square plate 2 and the workbench 1; by adding damping spring dampers 3 and baffle 31, the rotation speed of the square plate 2 can be reduced during rotation, thus reducing the impact with the workbench 1 and increasing the protection of the square plate 2.

[0028] like Figure 3 As shown, a connecting pipe 4 is fixedly connected to the side wall of the stack box 14; a nozzle 41 is connected to the end of the connecting pipe 4; the nozzle 41 is located at the connection between the gear 17 and the toothed plate 18; during operation, when using the gear 17 and the toothed plate 18, the connecting pipe 4 can be connected to an oil pump to transmit oil to the inside of the nozzle 41 and then spray it out at the connection between the gear 17 and the toothed plate 18, so that the oil lubricates it when meshing, reducing friction during contact; by adding the nozzle 41, the connection between the gear 17 and the toothed plate 18 can be lubricated, thus increasing its maintenance and extending its service life.

[0029] like Figures 1 to 5 As shown, a collection box 5 is provided at the bottom of the workbench 1; a sponge 51 is fixed inside the collection box 5; during operation, after the nozzle 41 sprays oil, some of the oil will drip down along the toothed plate 18. At this time, the collection box 5 is placed under the toothed plate 18 to collect the dripping oil and let it enter the collection box 5. Then it will come into contact with the sponge 51 and stay inside the collection box 5; by adding the collection box 5, the dripping oil can be collected, reducing its scattering. At the same time, when it comes into contact with the sponge 51, the oil will be quickly absorbed by the absorbency of the sponge 51, thereby reducing splashing.

[0030] like Figure 3 As shown, a damping rod 6 is fixedly connected to the bottom of the stacking box 14; the end of the damping rod 6 is fixedly connected to the push plate 19; during operation, the damping rod 6 will extend and compress as the push plate 19 moves, thereby supporting and guiding its movement; by adding the damping rod 6, the support of the other end of the push plate 19 can be increased through its own damping effect during the movement of the push plate 19, thus increasing its balance.

[0031] Working principle: Before use, the stacking box 14 is opened via the feeding assembly 15, and the PCB board is placed on top of the push plate 19 for stacking. After placement, the stacking box 14 is closed via the feeding assembly 15. At this time, the suction plate 13 is connected to the air pump through the pipe to generate negative pressure, and then the cylinder 12 is activated to move the suction plate 13 down towards the PCB board for suction. After one PCB board is suctioned out of the stacking box 14, the servo motor 16 is started to send the next PCB board to the position of the previous PCB board through the precise transmission between the gear 17 and the toothed plate 18. Thus, when the suction plate 13 suctions again, it descends to the same depth as before to contact the PCB board. Therefore, the suction is always performed at the same height, reducing the time required to adjust the suction plate 13. When feeding the stacking box 14, the pin inside the pin hole 21 is pulled out first, and then the square plate 2 is rotated to open the stacking box 14. After opening, the stacking box 14 can be accessed from the side. 4. The interior is filled with PCB board; after the square plate 2 is opened, it will rotate and gradually move towards the worktable 1. At this time, it will first contact the baffle 31, and then the baffle 31 will receive the force after the square plate 2 rotates. When it contacts the baffle 31, the damping spring shock absorber 3 will be compressed. During the compression, the rotation speed of the square plate 2 will be gradually reduced, and it will gradually stop rotating, thereby intercepting the impact between the square plate 2 and the worktable 1; in the gear 17 and toothed plate 18, the connecting pipe 4 can be connected to the oil pump to transmit oil to the spray. The oil is then sprayed from inside the nozzle 41 at the connection between the gear 17 and the toothed plate 18, so that the oil lubricates the connection during meshing and reduces friction during contact. After the nozzle 41 sprays the oil, some of the oil will drip down along the toothed plate 18. At this time, the collection box 5 is placed under the toothed plate 18 to collect the dripping oil and let it enter the collection box 5. Then it will come into contact with the sponge 51 and stay inside the collection box 5. When the push plate 19 moves, the damping rod 6 will extend and compress accordingly, thereby supporting and guiding its movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
