Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to an adjustable spacing PCB board stacking fixture. Background Technology

[0002] With the rapid development of electronic technology, printed circuit boards (PCBs), as a core component of electronic products, face higher requirements for positioning, fixing, and protection during production, testing, and transportation. Especially in the PCB assembly and testing stages, multiple PCBs often need to be vertically stacked to save space and improve efficiency. Traditional PCB fixing methods mostly use simple brackets or screws, resulting in a simplistic structure, inconvenient adjustment, and non-adjustable spacing between boards, making it difficult to accommodate PCBs of different sizes. Furthermore, the stacking spacing is also non-adjustable, making it difficult to accommodate PCBs of different thicknesses. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable-spacing PCB board stacking fixture, which solves the problems of current PCB fixing methods that mostly use simple brackets or screws for fixing, resulting in a single structure, inconvenient adjustment, and non-adjustable spacing between boards, making it difficult to adapt to PCB boards of different sizes. At the same time, the stacking spacing is also non-adjustable, making it difficult to adapt to PCB boards of different thicknesses.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-spacing PCB board stacking fixture, comprising a frame body, with rotating shafts rotatably connected to the upper and lower parts of the inner wall of the frame body, and fixed rods fixedly connected to both sides of the upper and lower parts of the frame body. Adjusting frames are installed on both sides of the outer wall of the rotating shafts, with the two sides of the adjusting frames slidably connected to the outer walls of the fixed rods. Connecting frames are slidably connected to both sides of the outer walls of the fixed rods. Vertical plates are fixedly connected to adjacent surfaces of the adjusting frames. Rotating rods are fixedly connected to the middle of the far-away surfaces of the adjusting frames and connecting frames. Connecting plates are rotatably connected to the outer walls of the rotating rods. Multiple connecting plates are connected by connecting rods. Wheels are fixedly connected to one side of the outer walls of the two rotating shafts, and belts are installed on the outer walls of the wheels. A motor is fixedly connected to the lower part of one side of the outer wall of the frame body, and the output end of the motor is fixedly connected to one end of one of the rotating shafts. Through slots are opened on both sides of adjacent surfaces inside the frame body, and the outer walls of the adjusting frames are slidably connected to the inner walls of the through slots.

[0005] As a preferred embodiment of this utility model, fixing plates are fixedly connected to the upper and lower parts of the opposite surfaces of the two upright plates. A placement plate is fixedly connected to the lower part of the adjacent surfaces of the two upright plates. A pressure plate is slidably connected to the upper part of the adjacent surfaces of the two upright plates. A placement plate is slidably connected to the middle of the adjacent surfaces of the two upright plates. A slider is fixedly connected to both sides of the placement plate and the pressure plate. The outer wall of the slider is slidably connected to the upright plate. A screw is rotatably connected to the middle of the adjacent surfaces of the fixing plate. A motor is fixedly connected to the middle of the fixing plate. The output end of the motor is fixedly connected to the bottom end of the screw. An adjusting block is fixedly connected to the middle of one side of the pressure plate. The inner wall of the adjusting block is threadedly connected to the outer wall of the screw. Support rods are fixedly connected to both sides of the adjacent surfaces of the fixing plate. The inner wall of the slider is slidably connected to the outer wall of the support rod. Springs are fixedly connected to the adjacent surfaces of the slider, and the springs are sleeved on the outer wall of the support rod.

[0006] As a preferred embodiment of this utility model, the vertical plate has sliding grooves on both sides and in the middle. The outer wall of the slider is slidably connected to the inner wall of the two side sliding grooves, and the outer wall of the adjusting block is slidably connected to the inner wall of the middle sliding groove.

[0007] As a preferred embodiment of this utility model, rubber pads are provided on both sides of the outer walls of the first placement plate, the second placement plate, and the pressure plate.

[0008] As a preferred technical solution of this utility model, a protective shell is fixedly connected to one side of the outer wall of the frame, and the motor, the wheel and the belt are arranged inside the protective shell.

[0009] Compared with the prior art, this utility model provides an adjustable-spacing PCB board stacking bracket, which has the following advantages:

[0010] 1. This adjustable spacing PCB board stacking fixing frame uses a starting motor to drive one of the rotating shafts to rotate. The two ends of the rotating shaft are connected to the other rotating shaft synchronously through the rotating wheels and belts, ensuring that the upper and lower rotating shafts rotate at the same time. This drives the adjusting frame to move laterally along the fixing rod. At the same time, the connecting frame, connecting plate, and connecting rod form a support linkage system, which can drive the two adjusting frames to move inward symmetrically at the same time, thereby changing the distance between the uprights and realizing the ability to adjust the spacing of the uprights according to the size of the PCB board.

[0011] 2. This adjustable spacing PCB board stacking fixture uses a drive motor to move an adjusting block, which in turn moves a pressure plate downwards. As the pressure plate slides downwards, it causes a slider to slide downwards, compressing a spring. This allows other sliders to move a placement plate downwards on a support rod, thus enabling the pressure plate, placement plate one, and placement plate two to clamp the PCB board, achieving clamping of PCB boards of different thicknesses.

[0017] 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 protection scope of the present utility model. Example 1

[0018] Please see Figure 1-4 In this embodiment: an adjustable-spacing PCB board stacking fixture includes a frame body 1. A rotating shaft 3 is rotatably connected to the upper and lower parts of the inner wall of the frame body 1. Fixing rods 4 are fixedly connected to both sides of the upper and lower parts of the frame body 1. Adjusting frames 5 are installed on both sides of the outer wall of the rotating shafts 3. The two sides of the adjusting frames 5 are slidably connected to the outer walls of the fixing rods 4. Connecting frames 6 are slidably connected to both sides of the outer walls of the fixing rods 4. Vertical plates 13 are fixedly connected to adjacent surfaces of the adjusting frames 5. The adjusting frames 5 and the connecting frames 6 are far apart. A rotating rod 7 is fixedly connected to the center of each surface. A connecting plate 8 is rotatably connected to the outer wall of the rotating rod 7. Multiple connecting plates 8 are connected by a connecting rod 9. A rotating wheel 11 is fixedly connected to one side of the outer wall of each of the two rotating shafts 3. A belt 12 is installed on the outer wall of the rotating wheel 11. A motor 10 is fixedly connected to the lower part of one side of the outer wall of the frame 1. The output end of the motor 10 is fixedly connected to one end of one of the rotating shafts 3. Through slots 2 are opened on both sides of the adjacent surfaces inside the frame 1. The outer wall of the adjusting frame 5 is slidably connected to the inner wall of the through slot 2.

[0019] In this embodiment, the starting motor 10 drives one of the rotating shafts 3 to rotate, which in turn drives the rotating wheel 11 to rotate. The belt 12 links the other rotating wheel 11, so that the two rotating shafts 11 rotate synchronously. The rotating shaft 3 drives the adjusting frame 5 to slide on the fixed rod 4. When the adjusting frame 5 moves, the connecting plate pulls the connecting frame 6 to slide on the fixed rod 4. The connecting frame 6, the connecting plate 8, and the connecting rod 9 form a support linkage system, which enables the two adjusting frames 5 to move inward at the same time, thereby driving the upright plate 13 to move inward to adjust the spacing. This realizes the adjustment of the spacing between the upright plates 13 according to the size of the PCB board.

[0020] Furthermore, fixing plates 14 are fixedly connected to the upper and lower parts of the opposite surfaces of the two upright plates 13. Placement plates 18 are fixedly connected to the lower parts of the adjacent surfaces of the two upright plates 13. Pressure plates 22 are slidably connected to the upper parts of the adjacent surfaces of the two upright plates 13. Placement plates 20 are slidably connected to the middle of the adjacent surfaces of the two upright plates 13. Slider blocks 19 are fixedly connected to both sides of placement plates 20 and pressure plates 22. The outer walls of sliders 19 are slidably connected to the upright plates 13. A rotating plate 14 is rotatably connected to the middle of the adjacent surfaces of the fixing plates 14. A second motor 16 is fixedly connected to the middle of the screw 17 and the fixing plate 14. The output end of the second motor 16 is fixedly connected to the bottom end of the screw 17. An adjusting block 21 is fixedly connected to the middle of one side of the pressure plate 22. The inner wall of the adjusting block 21 is threadedly connected to the outer wall of the screw 17. Support rods 15 are fixedly connected to both sides of the adjacent surfaces of the fixing plate 14. The inner wall of the slider 19 is slidably connected to the outer wall of the support rod 15. Springs 23 are fixedly connected to the adjacent surfaces of the slider 19. The springs 23 are sleeved on the outer wall of the support rod 15.

[0021] The PCB board is placed between placement plate 18, placement plate 20, and pressure plate 22. Then, motor 216 drives screw 17 to rotate, causing adjustment block 21 to move downward. This causes pressure plate 22 to slide downward. Slider 19 on both sides of pressure plate 22 slides on the outer wall of support rod 15, allowing slider 19 to compress spring 23. This causes other slider 19 to slide downward on the outer wall of support rod 15, which in turn causes placement plate 20 to slide downward. This allows placement plate 18, placement plate 20, and pressure plate 22 to clamp and press PCB boards of different thicknesses. At the same time, spring 23 is placed between slider 19 to provide elastic buffering force, enhance stability, and prevent excessive pressure on the PCB board.

[0022] Preferably, the vertical plate 13 has grooves 24 on both sides and in the middle, the outer wall of the slider 19 is slidably connected to the inner wall of the two side grooves 24, and the outer wall of the adjusting block 21 is slidably connected to the inner wall of the middle groove 24.

[0023] When the slider 19 and the adjusting block 21 slide, their outer walls slide on the inner wall of the slide groove 24.

[0024] Preferably, rubber pads 25 are provided on both sides of the outer wall of the first placement plate 18, the second placement plate 20, and the pressure plate 22;

[0025] The rubber pad 25 is placed on the contact surface of the pressure plate 22, the first placement plate 18 and the second placement plate 20, which can effectively prevent damage to the PCB board and improve the clamping friction.

[0026] Preferably, a protective shell 26 is fixedly connected to one side of the outer wall of the frame 1, and the motor 10, the wheel 11 and the belt 12 are arranged inside the protective shell 26.

[0027] The working principle and usage process of this utility model are as follows: Starting motor 10 drives one of the rotating shafts 3 to rotate, which in turn drives the rotating wheel 11 to rotate. A belt 12 links the other rotating wheel 11, achieving synchronous rotation of the two rotating shafts 11. The rotating shaft 3 drives the adjusting frame 5 to slide on the fixed rod 4. When the adjusting frame 5 moves, the connecting plate pulls the connecting frame 6 to slide on the fixed rod 4. The connecting frame 6, connecting plate 8, and connecting rod 9 form a support linkage system, enabling both adjusting frames 5 to move inward simultaneously. This, in turn, drives the upright plates 13 to move inward for spacing adjustment, allowing the spacing between the upright plates 13 to be adjusted according to the size of the PCB board. Then, the PCB board is placed on the first placement plate 18 and the second placement plate. Between the pressure plate 20 and the pressure plate 22, the screw 17 is rotated by starting the motor 16, which causes the adjusting block 21 to move downward, thereby causing the pressure plate 22 connected to it to slide downward. The sliders 19 on both sides of the pressure plate 22 slide on the outer wall of the support rod 15, thereby allowing the sliders 19 to squeeze the spring 23, causing the other sliders 19 to slide downward on the outer wall of the support rod 15, thereby causing the placement plate 20 to slide downward. Thus, the placement plate 18, placement plate 20 and pressure plate 22 can clamp and press PCB boards of different thicknesses. At the same time, the spring 23 is placed between the sliders 19 to provide elastic buffering force, enhance stability and prevent excessive pressure on the PCB board.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
