[0004] The existing technical solutions mentioned above have the following drawbacks: electronic components have different shapes and uneven surfaces. When pressed and clamped by a smooth pressing device, the surface of the electronic components is easily damaged. Therefore, we propose a multi-station fixing fixture for electronic assembly and testing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station fixing fixture for electronic assembly and testing, so as to solve the problem mentioned in the background art that electronic components have different shapes and uneven surfaces, and the surface of electronic components is easily damaged when pressed and clamped by a smooth pressing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station fixing fixture for electronic assembly and testing, comprising an assembly and testing platform, a fixing box fixedly installed in a ring around the upper periphery of the assembly and testing platform, a fixing clamping mechanism provided on the outer side of the fixing box, drive screws symmetrically installed on both sides of the fixing box, sliding blocks symmetrically installed above the drive screws, a clamping electric telescopic cylinder fixedly installed above the sliding blocks, a clamping mechanism fixedly installed between the clamping electric telescopic cylinders on the left and right sides of the fixing box, a clamping rod groove rectangularly opened inside the clamping mechanism, and a clamping rod slidably installed inside the clamping rod groove.

[0007] Preferably, the assembly test bench is equipped with a rotating shaft at the middle position of the assembly test bench.

[0008] Preferably, the clamping mechanism has a concave structure, and a compression spring groove is provided above the clamping rod groove. A compression spring is provided inside the compression spring groove. The upper end of the compression spring is in contact with the inner wall of the compression spring groove, and the lower end of the compression spring is in contact with the upper end of the clamping rod.

[0009] Preferably, the clamping mechanism has a push block groove inside, and a drive frame is slidably arranged inside the push block groove. The drive frame includes a push block, a locking clamp, a connecting plate, and a positioning frame.

[0010] Preferably, a drive frame is provided on the outer side of the drive frame, and a plurality of push blocks are provided in a rectangular arrangement inside the drive frame. The push blocks are located on one side of the locking clamp, and a connecting plate is fixedly installed between adjacent push blocks and between the push blocks and the positioning frame.

[0011] Preferably, the locking clip is located inside the clamping rod groove and is slidably connected to the clamping rod groove, the pushing block is located inside the pushing block groove and is slidably connected to the pushing block groove, the locking clip is in contact with the clamping rod, and the locking clip is arc-shaped.

[0012] Preferably, the clamping mechanism has an electric telescopic cylinder on one side, with one end of the electric telescopic cylinder extending into the interior of the clamping mechanism and fixedly connected to the middle position of one end of the drive frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the electronic components to be assembled and tested are placed inside the fixed box. Then, the drive screw is adjusted, causing two sliding blocks to slide towards the middle position on both sides of the fixed box. The sliding blocks, through the clamping electric telescopic cylinder, move the clamping mechanism to the top of the fixed box. At this point, the clamping electric telescopic cylinder retracts, causing the clamping mechanism to move downwards. Simultaneously, the clamping rod inside the clamping mechanism comes into contact with the surface of the electronic component, and the pressure is greater than the spring force of the compression spring, causing the clamping rod to retract into the clamping rod groove. Then, the electric telescopic cylinder extends, pushing the drive frame. The push blocks are arranged at equal intervals, and a locking clip is fixedly installed on one side of each push block. As the drive frame moves, the locking clip moves towards the clamping rod, causing the other end of the clamping rod to fit against the inner wall of the clamping rod groove on the other side, thereby clamping the clamping rod. At this time, the clamping rods fit against the edges of the electronic components, thereby pressing the electronic components. Due to the telescopic sliding clamping rod design, the clamping rods can completely fit the shape of the electronic component surface, ensuring that the electronic component is subjected to uniform force when pressed. This solves the problem that electronic components with different shapes and uneven surfaces are easily damaged when pressed and clamped by a smooth pressing device. Attached Figure Description

[0023] In use, the electronic components to be assembled and tested are placed inside the fixing box 2. Then, the drive screw 5 is adjusted, causing the two sliding blocks 6 to slide towards the middle position on both sides of the fixing box 2. The sliding blocks 6, through the clamping electric telescopic cylinder 7, move the clamping mechanism 8 to the top of the fixing box 2. At this point, the clamping electric telescopic cylinder 7 retracts, causing the clamping mechanism 8 to move downwards. Simultaneously, the clamping rod 9 inside the clamping mechanism 8 comes into contact with the surface of the electronic component, and the pressure exceeds the elastic force of the compression spring 11, causing the clamping rod 9 to retract into the clamping rod groove 12. Then, the electric telescopic cylinder 16 extends. 16 pushes the drive frame 10. The push blocks 14 on the drive frame 10 are arranged at equal intervals. A locking clip 15 is fixedly installed on one side of the push block 14. As the drive frame 10 moves, the locking clip 15 moves towards the clamping rod 9, so that the other end of the clamping rod 9 fits against the inner wall of the other side of the clamping rod groove 12, thereby clamping the clamping rod 9. At this time, the clamping rod 9 fits against the edge of the electronic component, thereby pressing the electronic component. Due to the telescopic sliding clamping rod 9, the clamping rod 9 can completely fit the shape of the surface of the electronic component, so that the electronic component is subjected to uniform force when pressed.

[0024] Please see Figure 1 The assembly test bench 4 is installed at the middle position of the assembly test bench 1.

[0025] Please see Figure 4 The clamping mechanism 8 has a concave structure. A compression spring groove 13 is provided above the clamping rod groove 12. A compression spring 11 is provided inside the compression spring groove 13. The upper end of the compression spring 11 is in contact with the inner wall of the compression spring groove 13, and the lower end of the compression spring 11 is in contact with the upper end of the clamping rod 9.

[0026] Please see Figure 4-6 The clamping mechanism 8 has a push block groove 17 inside, and a drive frame 10 is slidably arranged inside the push block groove 17. The drive frame 10 includes push blocks 14, locking clips 15, connecting plates 18, and positioning frames 19. The drive frame 10 is arranged on the outside, and multiple push blocks 14 are rectangularly arranged inside the drive frame 10. The push blocks 14 are located on one side of the locking clips 15, and connecting plates 18 are fixedly installed between adjacent push blocks 14 and between the push blocks 14 and the positioning frames 19. The locking clips 15 are located inside the clamping rod grooves 12 and are slidably connected to the clamping rod grooves 12. The push blocks 14 are located inside the push block grooves 17 and are slidably connected to the push block grooves 17. The locking clips 15 are in contact with the clamping rods 9 and are arc-shaped. An electric telescopic cylinder 16 is located on one side of the clamping mechanism 8. One end of the electric telescopic cylinder 16 extends into the interior of the clamping mechanism 8 and is fixedly connected to the middle position of one end of the drive frame 10.

[0027] Working principle: During use, the electronic components to be assembled and tested are placed inside the fixing box 2. The drive screw 5 is then adjusted, causing the two sliding blocks 6 to slide towards the middle position on both sides of the fixing box 2. The sliding blocks 6, through the clamping electric telescopic cylinder 7, move the clamping mechanism 8 to the top of the fixing box 2. At this point, the clamping electric telescopic cylinder 7 retracts, causing the clamping mechanism 8 to move downwards. Simultaneously, the clamping rod 9 inside the clamping mechanism 8 comes into contact with the surface of the electronic component, and the pressure exceeds the elastic force of the compression spring 11, causing the clamping rod 9 to retract into the clamping rod groove 12. Then, the electric telescopic cylinder 16 extends, extending the electric... The telescopic cylinder 16 pushes the drive frame 10. The push blocks 14 on the drive frame 10 are arranged at equal intervals. A locking clip 15 is fixedly installed on one side of the push block 14. As the drive frame 10 moves, the locking clip 15 moves towards the clamping rod 9, so that the other end of the clamping rod 9 fits against the inner wall of the other side of the clamping rod groove 12, thereby clamping the clamping rod 9. At this time, the clamping rod 9 fits against the edge of the electronic component, thereby pressing the electronic component. Due to the telescopic sliding clamping rod 9, the clamping rod 9 can completely fit the shape of the surface of the electronic component, so that the electronic component is subjected to uniform force when pressed.
