[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a circuit board pushing and positioning structure for a circuit board testing machine, comprising: a placement board body 1, two grooves 2 are provided on the top of the placement board body 1, a pushing component 3 is provided inside the grooves 2, and two grooves 4 are provided on the top of the placement board body 1, an adjustment component 5 is provided inside the grooves 4, the adjustment component 5 includes a round rod 501, a slider 502, a spring 503, an adjustment plate 504, and a protective plate 505. One end of the round rod 501 is fixedly installed on one end of the inner wall of the groove 4, and the other end of the round rod 501 is fixedly installed on the other end of the inner wall of the groove 4. The inner wall of the slider 502 is movably sleeved on the surface of the round rod 501, the inner wall of the spring 503 is movably sleeved on the surface of the round rod 501, the bottom of the adjustment plate 504 is fixedly installed on the top of the slider 502, and one side of the protective plate 505 is fixedly installed on one side of the adjustment plate 504.

[0023] Specifically: When the device is first used, the circuit board is placed on the device. Slider 502 is movably fitted onto the surface of the round rod 501, and spring 503 is movably fitted onto the surface of the round rod 501. The elasticity of spring 503 drives the adjustment plate 504, which is fixedly mounted on top of slider 502, to move, thus initially positioning the circuit board. A protective plate 505, fixedly mounted on one side of the adjustment plate 504, contacts the surface of the circuit board, protecting it and reducing wear. The elasticity of spring 503 causes the adjustment plate 504 to apply pressure to the circuit board, causing the circuit board to shift at an angle under the action of the protective plate 505, thus adjusting the circuit board and reducing offset. Then, the push assembly 3 is activated to push and position the circuit board, allowing for better testing and making the device more complete.

[0024] In one embodiment, the push-back assembly 3 includes a motor 301. The output end of the motor 301 is fixedly installed on one side of the placement plate body 1. A threaded rod 302 is fixedly installed on the output end of the motor 301. A connecting block 303 is fixedly installed on the other end of the threaded rod 302. A threaded rod 304 is fixedly installed on the other end of the connecting block 303. The other end of the threaded rod 304 is installed on one end of the inner wall of the groove 2 via a bearing. A slider 305 is threadedly fitted on the surfaces of both the threaded rod 302 and the threaded rod 304. The surface of the slider 305 is movably installed on the inner wall of the groove 2. A push-back plate 306 is fixedly installed on the top of the slider 305. A protective plate 307 is fixedly installed on one side of the push-back plate 306.

[0025] Specifically: The motor 301, powered by an external power source, drives threaded rod 302 and threaded rod 304. Because the threads of threaded rods 302 and 304 are opposite, the sliders 305 threaded onto their surfaces move in opposite directions. This causes the push plate 306, fixedly mounted on the top of slider 305, to move in opposite directions, pushing and clamping the circuit board for better positioning and stability. A protective plate 307 fixedly mounted on one side of the push plate 306 protects the circuit board, reducing wear and making the device more complete.

[0026] In one embodiment, one end of the spring 503 is fixedly installed on one side of the slider 502, and the other end of the spring 503 is fixedly installed on one end of the inner wall of the groove 4.

[0027] Specifically: one end of spring 503 is fixedly installed on one side of slider 502, and the other end of spring 503 is fixedly installed on one end of the inner wall of groove 4, so that spring 503 is more stably fitted on the surface of round rod 501, making the device more perfect.

[0028] In one embodiment, a damping block 6 is fixedly installed on one side of the slider 502, and the inner wall of the damping block 6 is movably sleeved on the surface of the round rod 501.

[0029] Specifically: After the circuit board is placed, the damping block 6, which is fixedly installed on one side of the slider 502, is sleeved on the surface of the round rod 501. Through the restriction of the damping block 6, when the spring 503 drives the slider 502 to move, the slider 502 can slide slowly on the surface of the round rod 501, preventing the slider 502 from moving too fast and causing damage to the circuit board, thus making the device more perfect.

[0030] In one embodiment, a limiting groove 7 is provided on the surface of the round rod 501, and a limiting rod 8 is movably installed inside the slider 502 and the adjusting plate 504. The surface of the limiting rod 8 is movably installed on the inner wall of the limiting groove 7.

[0031] Specifically: After the circuit board is placed, the limiting rod 8 installed inside the slider 502 and the adjusting plate 504 is pulled out from the limiting groove 7 opened on the surface of the round rod 501 to release the restriction, so that the elasticity of the spring 503 is released, and the slider 502 will move under the elasticity of the spring 503, making the device more perfect.

[0032] In one embodiment, a support rod 9 is fixedly installed on the top of the placement plate body 1, and there are four support rods 9. A placement piece 10 is fixedly installed on the top of the support rod 9.

[0033] Specifically: The circuit board is placed on top of the placement plate 10 fixedly installed on top of the support rod 9. The support rod 9 supports the circuit board. The placement plate 10 is made of polytetrafluoroethylene, which has a low coefficient of friction, reducing friction with the surface of the circuit board and preventing scratches. It has high chemical stability and will not corrode the circuit board, so the circuit board will not be separated from the placement plate, reducing wear on the circuit board and making the device more perfect.

[0034] Working Principle: When the device is first used, the circuit board is placed on top of the placement plate 10. The limiting rod 8 installed inside the slider 2 502 and the adjusting plate 504 is pulled out from the limiting groove 7 opened on the surface of the round rod 501, releasing the restriction and releasing the elasticity of the spring 503. The slider 2 502 moves under the elasticity of the spring 503. When the spring 503 drives the slider 2 502 to move, the damping block 6 fixedly installed on one side of the slider 2 502 restricts the movement, causing the slider 2 502 to move slowly and preventing damage to the circuit board. The adjusting plate 504 performs initial positioning of the circuit board. During the positioning process, the adjusting plate 504 applies pressure to the circuit board, making the surface of the circuit board fit with the surface of the protective plate 2 505, thus adjusting the circuit board and correcting the offset during placement. Then, the motor 301 is started by the external power supply to drive the threaded rod 1 302 and the threaded rod 2 505. Rod 2 304, through the opposite threads of threaded rod 1 302 and threaded rod 2 304, causes slider 1 305, which is threaded onto the surfaces of threaded rod 1 302 and threaded rod 2 304, to move in opposite directions. This causes the push plate 306, which is fixedly mounted on the top of slider 1 305, to move in opposite directions, pushing and clamping the circuit board, so that the circuit board is better positioned and stable. The protective plate 307, which is fixedly mounted on one side of the push plate 306, protects the circuit board and reduces wear, making the device more complete. When the device is used, the circuit board is placed on top of the placement plate 10, which is fixedly mounted on the top of the support rod 9. The support rod 9 supports the circuit board. The placement plate 10 is made of polytetrafluoroethylene, which has a low coefficient of friction, reduces friction with the surface of the circuit board, avoids scratches, has high chemical stability, and will not corrode the circuit board, so that the circuit board will not be separated from the placement plate, reducing wear on the circuit board and making the device more complete.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
