Description

Technical Field

[0001] This utility model relates to the field of mechanism board testing technology, and specifically to a mechanism board testing device. Background Technology

[0002] With the advancement of science and technology, the electronics industry has developed rapidly. Electronic systems are becoming increasingly complex, and the requirements for their reliability and maintainability are also increasing. As an important component in the research and development and production of electronic systems, the quality of the core board directly affects the quality of the entire equipment. Therefore, testing equipment is required to test the core board before it leaves the factory.

[0003] However, when using existing movement board testing devices, the movement board fixing device on the testing device can only fix the movement board according to a single movement board size. When testing movement boards of different sizes, the fixing device needs to be replaced, which makes the testing efficiency low. In addition, when fixing the movement board, the clamps on it are easy to damage the movement board, causing unnecessary losses, which makes it inconvenient to promote its use.

[0004] To address this problem, this application provides a mechanism board testing device. Utility Model Content

[0005] The purpose of this utility model is to provide a mechanism board testing device to solve the problems mentioned in the background art, which can only fix the mechanism board according to a single mechanism board size, and the fixture is prone to damaging the mechanism board. This results in the need to change the fixing device when testing mechanism boards of different sizes, reducing testing efficiency, causing unnecessary losses, and having poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A mechanism board testing device includes a support assembly, a clamping assembly, and a control assembly. The support assembly includes a support plate and a support frame, with the support frame fixedly connected to the top of the support plate. The clamping assembly is disposed inside the support assembly and includes a first screw and a movable plate, with the movable plate threaded onto the outside of the first screw. The control assembly is disposed inside the support assembly and includes a pressure sensor, which is fixedly installed inside the support frame.

[0008] A further improvement of this utility model is that: a support leg is fixedly installed at the bottom of the support plate, a frame is fixedly installed at the top of the support plate, and the top of the frame is fixedly installed at the bottom of the support frame.

[0009] A further improvement of this utility model is that: a workbench is fixedly installed on the top of the support frame, a second motor is fixedly installed inside the frame, the first screw is rotatably installed inside the support frame, and a second screw is rotatably installed inside the support frame.

[0010] A further improvement of the present invention is that a first motor is fixedly installed on the top of the support plate, a drive wheel is fixedly installed on one end of the first motor, and a belt is movably connected to the outside of the drive wheel.

[0011] A further improvement of this utility model is that: the other end of the belt is movably connected to a driven wheel, the first screw is fixedly installed inside the driven wheel, a clamping block is fixedly installed on the top of the movable plate, and the movable plate is slidably installed inside the support frame.

[0012] A further improvement of this utility model is that: a controller is fixedly installed on one side of the support frame, a movable plate is fixedly installed on one side of the movable plate, the movable plate is slidably installed inside the support frame, and a spring is movably connected to the outside of the movable plate.

[0013] A further improvement of this utility model is that: the spring is disposed inside the support frame, and the other end of the spring is movably connected to a fixing plate, which is disposed at one end of the pressure sensor.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a core board testing device. When testing a core board, the first motor, the first screw, and the moving plate work together to drive the first screw and the second screw to rotate, causing the moving plate to move the clamping block inside the support frame to fix the core board to be tested. For core boards of different sizes, there is no need to change the fixing device, thus improving testing efficiency.

[0016] 2. This utility model provides a core plate testing device. Under the combined action of a spring and a pressure sensor, when the core plate to be tested is fixed, the moving plate will drive the movable plate to move, causing the movable plate to compress the spring. The spring force is then transmitted to the pressure sensor through the fixed plate, thereby obtaining the clamping force generated by the fixing device on the core plate to be tested. When the clamping force is too large, the operation of the two motors will be stopped to prevent damage to the core plate and avoid unnecessary losses. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a core board testing device, including a support assembly 1, a clamping assembly 2, and a control assembly 3. The support assembly 1 includes a support plate 10 and a support frame 12. The support frame 12 is fixedly connected to the top of the support plate 10. A support leg 11 is fixedly installed at the bottom of the support plate 10. A frame 14 is fixedly installed at the top of the support plate 10. The top of the frame 14 is fixedly installed at the bottom of the support frame 12. A workbench 13 is fixedly installed at the top of the support frame 12. The core board to be tested is placed on the workbench 13.

[0025] like Figure 2-5As shown, the clamping assembly 2 is disposed inside the support assembly 1. The clamping assembly 2 includes a first screw 25 and a movable plate 27. The movable plate 27 is threaded onto the outside of the first screw 25. A second motor 22 is fixedly installed inside the frame 14. The first screw 25 is rotatably installed inside the support frame 12. A second screw 26 is rotatably installed inside the support frame 12. A first motor 20 is fixedly installed on the top of the support plate 10. A drive wheel 21 is fixedly installed on one end of the first motor 20. A belt 23 is movably connected to the outside of the drive wheel 21. A driven wheel 24 is movably connected to the other end of the belt 23. The first screw 25 is fixedly installed inside the driven wheel 24. The top of the movable plate 27... A clamping block 28 is fixedly installed, and a movable plate 27 is slidably installed inside the support frame 12. The first motor 20 and the second motor 22 drive the drive wheel 21 to rotate, and the drive wheel 21 drives the driven wheel 24 to rotate through the belt 23. The driven wheel 24 drives the first screw 25 and the second screw 26 to rotate, so that the movable plate 27 moves inside the support frame 12. The movable plate 27 then drives the clamping block 28 to move and fix the core plate to be tested. With the combined action of the first motor 20, the first screw 25 and the movable plate 27, there is no need to change the fixing device when dealing with core plates of different sizes, thus improving testing efficiency.

[0026] like Figure 1 and Figure 5 As shown, the control component 3 is located inside the support component 1. The control component 3 includes a pressure sensor 34, which is fixedly installed inside the support frame 12. A controller 30 is fixedly installed on one side of the support frame 12, and a movable plate 31 is fixedly installed on one side of the moving plate 27. The movable plate 31 is slidably installed inside the support frame 12. A spring 32 is movably connected to the outside of the movable plate 31, which is located inside the support frame 12. A fixed plate 33 is movably connected to the other end of the spring 32. The fixed plate 33 is located at one end of the pressure sensor 34. When the core plate to be tested is fixed, the moving plate 27 will drive the movable plate 31 on one side to move, causing the movable plate 31 to compress the spring 32. The elastic force of the spring 32 is transmitted to the pressure sensor 34 through the fixed plate 33, thereby obtaining the clamping force generated by the fixing device on the core plate to be tested. When the clamping force is too large, the operation of the first motor 20 and the second motor 22 is stopped to prevent the clamping force from being too large. Under the joint action of the spring 32 and the pressure sensor 34, the core plate is prevented from being damaged, causing unnecessary losses.

[0027] The working principle of this core board testing device will be explained in detail below.

[0028] like Figure 1-5As shown, when using this core board testing device, the core board to be tested is placed on the workbench 13. Then, the controller 30 drives the first motor 20 and the second motor 22. The first motor 20 and the second motor 22 drive the drive wheel 21 to rotate. The drive wheel 21 then drives the driven wheel 24 to rotate via the belt 23. The driven wheel 24 then drives the first screw 25 and the second screw 26 to rotate, causing the moving plate 27 to move inside the support frame 12. The moving plate 27 then drives the clamping block 28 to move, fixing the core board to be tested. The first motor 20, the first screw 25, and the moving plate 27 are used to fix the core board to be tested. Under the combined action of the two, when facing core plates of different sizes, there is no need to change the fixing device, which improves the testing efficiency. When fixing the core plate to be tested, the moving plate 27 will drive the movable plate 31 on one side to move, so that the movable plate 31 compresses the spring 32, and the elastic force of the spring 32 is transmitted to the pressure sensor 34 through the fixing plate 33, thereby obtaining the clamping force generated by the fixing device on the core plate to be tested. When the clamping force is too large, the operation of the first motor 20 and the second motor 22 will be stopped to prevent the clamping force from being too large. Under the combined action of the spring 32 and the pressure sensor 34, the core plate will not be damaged, causing unnecessary losses.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
