After clamping and fixing the equipment casing to be mounted on the circuit board, the circuit board is manually placed in for installation. This is cumbersome to operate and requires a high level of skill from the operator, and it does not have the function of automatically positioning and unloading the board.

[0004] Now, a novel circuit board mounting and positioning fixture is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a circuit board mounting and positioning fixture to solve the problem mentioned in the background art of not having the function of automatically positioning and unloading the board.

[0007] The moving plate assembly includes a top fixing plate, which is positioned above a bottom support plate. Side brackets are fixedly connected to the left and right sides of the bottom support plate, and a top slot is provided at the top of each side bracket. A drive threaded shaft is laterally movably connected between the two sides inside the top fixing plate. An internal threaded slider is sleeved on the outside of the drive threaded shaft. Limit blocks are fixedly connected to the front and rear ends of the internal threaded slider. Servo motors are installed on the left and right sides of the top fixing plate. An electric cylinder is fixedly connected to the bottom end of the internal threaded slider. A pressure plate is fixedly connected to the output end of the electric cylinder. Multiple sets of air guide metal pipes are installed on both sides of the pressure plate. A rubber suction cup is provided at the bottom end of each air guide metal pipe, and a vacuum pump nozzle is fixedly connected to the top end of each air guide metal pipe.

[0008] As a further technical solution of this utility model, the top slot and the top fixing plate are engaged, and the side bracket and the top fixing plate are fixedly connected.

[0009] As a further technical solution of this utility model, the external thread of the drive threaded shaft and the internal thread of the internal threaded slider are matched, and the two sides of the drive threaded shaft are respectively connected to the output end of the servo motor.

[0010] As a further technical solution of this utility model, the shape and size of the limiting block and the top fixing plate are adapted to each other, the limiting block can slide left and right along the inside of the top fixing plate, and the controller, servo motor and electric cylinder are electrically connected.

[0011] As a further technical solution of this utility model, a limiting ring is fixedly connected to the outside of the air guide metal pipe, a limiting nut is sleeved on the top of the outside of the air guide metal pipe, and metal pipe grooves are respectively opened on the left and right sides of the pressure plate.

[0012] As a further technical solution of this utility model, the outside of the air guide metal tube is threaded, the threads on the outside of the air guide metal tube match the threads inside the limiting nut, and the metal tube grooves are arranged at equal intervals.

[0013] As a further technical solution of this utility model, pre-cut slots are respectively opened on both sides of the top of the bottom support plate, and a housing limiting plate and a circuit board limiting plate are respectively horizontally placed on both sides of the top of the bottom support plate. A housing slot is provided at the top of the housing limiting plate, and a circuit board slot is provided at the top of the circuit board limiting plate. Circuit board limiting rods are glued to the four corners at the bottom of the circuit board slot.

[0014] As a further technical solution of this utility model, the shape and size of the bottom end of the housing limiting plate and the circuit board limiting plate are adapted to the shape and size of the pre-grooved interior, and the top ends of the housing limiting plate and the circuit board limiting plate are flush.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the circuit board mounting and positioning fixture not only realizes the function of easy automatic positioning of the unloading board, but also realizes the function of adjustable suction cup position, and also realizes the function of modular and easy replacement of the limiting plate.

[0016] The device is equipped with a side bracket, top slot, top fixing plate, drive threaded shaft, internal threaded slider, limit block, servo motor, electric cylinder, pressure plate, air guide metal pipe, rubber suction cup, and vacuum pump nozzle. In use, the device housing to be installed with the circuit board is placed into the housing limit plate, and the circuit board to be installed is placed into the circuit board limit plate. The vacuum pump is connected to the vacuum pump nozzle. The controller starts the servo motor, which drives the internal threaded slider to slide left and right along the inside of the top fixing plate via the drive threaded shaft. The limit block ensures smooth sliding. As the pressure plate reaches above the circuit board, the electric cylinder extends downwards, and the rubber suction cup adheres to the surface of the circuit board to attract it. The electric cylinder retracts. Once the pressure plate moves above the housing, the electric cylinder extends downwards again, placing the circuit board horizontally inside the housing. The vacuum pump stops suction, and the rubber suction cup loses its suction force on the circuit board, completing the unloading process. The operation is relatively simple, requires no operator experience, and facilitates automatic positioning and unloading.

[0017] By setting a limiting ring, a limiting nut, and a metal tube groove, the position of the rubber suction cup can be adjusted according to the specifications and layout of the circuit board during use. By screwing the limiting nut upward, the distance between the limiting ring and the limiting nut increases, thus releasing the pressure on the pressure plate. The air guide metal tube can then move left and right along the inside of the metal tube groove. By retightening the limiting nut at the appropriate position, the limiting ring and the limiting nut clamp the pressure plate, thereby fixing the position of the air guide metal tube and the rubber suction cup, realizing the function of adjustable suction cup position.

[0018] By incorporating pre-grooved slots, housing limiting plates, housing slots, circuit board limiting plates, circuit board slots, and circuit board limiting rods, users can select the appropriate housing limiting plates and circuit board limiting plates according to the specifications of the equipment housing and circuit board. These are then inserted into the pre-grooved slots, the equipment housing is directly inserted into the housing slots, and the circuit board is directly inserted into the circuit board slots. The circuit board limiting rods are compatible with the screw holes on the circuit boards for easy positioning. The pre-grooved slot design allows for easy replacement of the modular housing limiting plates and circuit board limiting plates, enabling easy replacement of the limiting plates.

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 protection scope of the present utility model.

[0027] Please see Figure 1-5 A circuit board mounting and positioning fixture also includes a plate shifting assembly. The plate shifting assembly includes a top fixing plate 5, which is set above a bottom support plate 1. Side brackets 3 are fixedly connected to the left and right sides of the bottom support plate 1, and a top slot 4 is opened at the top of the side brackets 3. A drive threaded shaft 6 is laterally movably connected between the two sides inside the top fixing plate 5. An internal threaded slider 7 is sleeved on the outside of the drive threaded shaft 6. Limit blocks 8 are fixedly connected to the front and rear ends of the internal threaded slider 7. Servo motors 9 are installed on the left and right sides of the top fixing plate 5. An electric cylinder 10 is fixedly connected to the bottom end of the internal threaded slider 7. A pressure plate 11 is fixedly connected to the output end of the electric cylinder 10. Multiple sets of air guide metal pipes 12 are installed on both sides of the pressure plate 11. A rubber suction cup 13 is provided at the bottom end of the air guide metal pipe 12. A vacuum pump nozzle 14 is fixedly connected to the top end of the air guide metal pipe 12.

[0028] The top slot 4 and the top fixing plate 5 engage with each other, the side bracket 3 and the top fixing plate 5 are fixedly connected, the external thread of the drive threaded shaft 6 and the internal thread of the internal threaded slider 7 are matched, the two sides of the drive threaded shaft 6 are respectively connected to the output end of the servo motor 9, the shape and size of the limit block 8 and the top fixing plate 5 are adapted, the limit block 8 can slide left and right along the inside of the top fixing plate 5, the controller 2, the servo motor 9 and the electric cylinder 10 are electrically connected to facilitate automatic plate unloading;

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the servo motor 9 drives the internal threaded slider 7 to slide left and right along the inside of the top fixed plate 5 through the drive threaded shaft 6. The limit block 8 makes its sliding smooth. As the pressure plate 11 reaches the top of the circuit board, the electric cylinder 10 extends downward, and the rubber suction cup 13 adheres to the surface of the circuit board to attract it. The electric cylinder 10 retracts. After the pressure plate 11 moves to the top of the housing, the electric cylinder 10 extends downward to place the circuit board horizontally into the housing. The vacuum pump stops suction, and the rubber suction cup 13 loses its suction force on the circuit board, thus completing the unloading process. The operation is relatively simple and does not require the operator to have experience. The controller 2, servo motor 9, and electric cylinder 10 are electrically connected. This technology is existing technology and will not be described in detail.

[0030] A limiting ring 15 is fixedly connected to the outside of the air guide metal tube 12, and a limiting nut 16 is sleeved on the top of the outside of the air guide metal tube 12. Metal tube grooves 17 are respectively opened on the left and right sides of the pressure plate 11. The outside of the air guide metal tube 12 is threaded, and the threads on the outside of the air guide metal tube 12 match the threads inside the limiting nut 16. The metal tube grooves 17 are arranged at equal intervals to facilitate the adjustment of the suction cup position.

[0031] Specifically, such as Figure 3 and Figure 5 As shown, by screwing the limiting nut 16 upward, the distance between the limiting ring 15 and the limiting nut 16 increases, thus releasing the pressure on the pressure plate 11. The air guide metal tube 12 can then move left and right along the inside of the metal tube groove 17. By tightening the limiting nut 16 again at the appropriate position, the limiting ring 15 and the limiting nut 16 clamp the pressure plate 11, thus completing the fixation of the positions of the air guide metal tube 12 and the rubber suction cup 13.

[0032] The bottom support plate 1 has pre-cut slots 18 on both sides of the top. The bottom support plate 1 has a housing limiting plate 19 and a circuit board limiting plate 21 horizontally placed on both sides of the top. The top of the housing limiting plate 19 has a housing slot 20 and the top of the circuit board limiting plate 21 has a circuit board slot 22. The four corners of the bottom of the circuit board slot 22 are glued with circuit board limiting rods 23. The shape and size of the bottom of the housing limiting plate 19 and the circuit board limiting plate 21 are compatible with the shape and size of the pre-cut slots 18. The tops of the housing limiting plate 19 and the circuit board limiting plate 21 are flush, which makes it easy to replace the limiting plates.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, select the corresponding specifications of the housing limiting plate 19 and circuit board limiting plate 21, and snap them into the pre-cut slot 18. The equipment housing is directly inserted into the housing slot 20, and the circuit board is directly snapped into the circuit board slot 22. The circuit board limiting rod 23 and the screw holes on the circuit board are matched to facilitate its positioning. The direct snapping of the pre-cut slot 18 makes it easy to replace the modular housing limiting plate 19 and circuit board limiting plate 21.

[0034] Working principle: When using this utility model, firstly, the device housing to be installed with the circuit board is placed into the housing limiting plate 19, and the circuit board to be installed is placed into the circuit board limiting plate 21. The vacuum pump is connected to the vacuum pump connector 14, and the servo motor 9 is started by the controller 2. The servo motor 9 drives the internal thread slider 7 to slide left and right along the inside of the top fixed plate 5 through the drive threaded shaft 6. The limiting block 8 makes the sliding smooth. As the pressure plate 11 reaches above the circuit board, the electric cylinder 10 extends downward, and the rubber suction cup 13 adheres to the surface of the circuit board to attract it. The electric cylinder 10 retracts. After the pressure plate 11 moves to the top of the housing, the electric cylinder 10 extends downward to place the circuit board horizontally into the inside of the housing. The vacuum pump stops suction, and the rubber suction cup 13 loses its suction force on the circuit board, thus completing the unloading process. The operation is relatively simple and does not require any experience from the operator. According to the specifications and layout of the circuit board, the position of the rubber suction cup 13 can be adjusted. By screwing the limiting nut 16 upward, the distance between the limiting ring 15 and the limiting nut 16 increases, thus releasing the pressure on the pressure plate 11. The air guide metal tube 12 can then move left and right along the inside of the metal tube groove 17. After tightening the limiting nut 16 at the appropriate position, the limiting ring 15 and the limiting nut 16 clamp the pressure plate 11, thus completing the fixation of the position of the air guide metal tube 12 and the rubber suction cup 13. According to the specifications of the equipment housing and the circuit board, select the corresponding specifications of the housing limiting plate 19 and the circuit board limiting plate 21, and snap them into the pre-cut groove 18. The equipment housing is directly inserted into the housing slot 20, and the circuit board is directly snapped into the circuit board slot 22. The circuit board limiting rod 23 is adapted to the screw holes on the circuit board for easy positioning. The direct snap-in form of the pre-cut groove 18 facilitates the replacement of the modular housing limiting plate 19 and the circuit board limiting plate 21.
