Description

Technical Field

[0001] This utility model relates to the field of circuit board load function testing technology, and in particular to a fixing device for circuit board load function testing. Background Technology

[0002] Circuit board load function testing is a key step in verifying the performance, stability and reliability of circuit boards under normal or extreme conditions. It is especially important in scenarios involving current and voltage output, such as power supplies and power drives. Through systematic load testing, the reliability of circuit boards can be effectively verified, ensuring their stable operation in practical applications.

[0003] Currently, the circuit board load function test process is usually performed by clamping with a clamp. However, the mechanical force of clamping may damage the edges of the circuit board during the clamping process. In addition, the surface of the circuit board needs to be manually cleaned before the circuit board is tested, which consumes a lot of time and manpower. The path for manual cleaning is also low. After cleaning, the circuit board needs to be dried. During the testing process, the cleaning fluid may affect the test function. Utility Model Content

[0021] Reference Figures 1-5 A mounting device for circuit board load function testing, comprising:

[0022] The workbench 1 and the circuit board body 6 are connected. A storage tube 24 is fixedly installed on the side wall of the workbench 1, and two hooks are fixedly connected to the side wall of the workbench 1. The storage tube 24 and the hanging rod can store and hang some parts and tools, which is convenient for use during the testing process. Two clamping plates 1 2 are slidably connected to the upper side of the workbench 1. Compression springs 1 3 are fixedly connected to the workbench 1 between the two clamping plates 1 2 and the workbench 1. Two clamping plates 2 4 are slidably connected to the upper side of the workbench 1. Compression springs 2 5 are fixedly connected to the workbench 1 between the two clamping plates 2 4 and the workbench 1. The elastic force of the compression springs 1 3 and compression springs 2 5 keeps the circuit board body stable. The circuit board 6 can be fixedly clamped. The two clamping plates 2 and 4 are all fixedly installed with sponge pads 23 on their side walls. The sponge pads 23 can reduce the damage to the circuit board body 6 by their softness. The upper side of the workbench 1 is fixedly connected to a support block, and the lower side of the workbench 1 is fixedly connected to four support columns 8. The side wall of the workbench 1 is fixedly connected to a support plate 9. The upper side of the support plate 9 is fixedly installed with a light 25. The light 25 can provide illumination for the testing process, making the field of vision better during the test. The side wall of the support plate 9 is fixedly connected to a fixing plate 10, and a cleaning structure is installed on the fixing plate 10.

[0023] The cleaning structure includes a control motor 11 rotatably connected to the side wall of the fixed plate 10. A threaded rod 12 is fixedly installed at the output end of the control motor 11. A slide plate 13 is threadedly connected to the outer side of the threaded rod 12. A fixed rod 26 is fixedly connected to the side wall of the fixed plate 10. The slide plate 13 is slidably connected to the fixed rod 26. The fixed rod 26 acts as a constraint, allowing the slide plate 13 to slide by rotating the threaded rod 12. Multiple nozzles 14 are fixedly connected to the side wall of the slide plate 13. A liquid storage tank 15 is fixedly installed on the upper side of the slide plate 13. The liquid storage tank 15 stores cleaning fluid. The cleaning fluid can be sprayed onto the upper side of the circuit board body 6 through the nozzles 14. The cleaning fluid sprayed by the nozzles 14 is fine, so that a large amount of cleaning fluid will not appear on the upper side of the circuit board body 6. A cleaning plate 7 is fixedly connected to the lower side of the slide plate 13. The cleaning plate 7 can clean the dust on the upper side of the circuit board body 6, and the cleaning plate 7 can be replaced.

[0024] A blower structure is installed on the slide plate 13. The blower structure includes multiple rotating shafts 16 rotatably connected to the upper side of the slide plate 13. A rotating shaft 17 is rotatably connected to the upper side of the slide plate 13. One of the rotating shafts 16 and the rotating shaft 17 are connected by a pulley assembly 18. The rotating shaft 16 and the rotating shaft 17 are closest to each other. The pulley assembly 18 consists of two pulleys and a belt. A spur gear 19 is fixedly sleeved on the outer side of the rotating shaft 17. A rack 20 is fixedly connected to the side wall of the fixing plate 10, and the spur gear 19 meshes with the rack 20. A spur gear 21 is fixedly sleeved on the outer side of each of the multiple rotating shafts 16, and adjacent spur gears 21 mesh with each other. A fan 22 is fixedly installed on one end of some of the rotating shafts 16.

[0025] In this invention, firstly, the operator clamps the circuit board body 6 using two clamping plates 2 and two clamping plates 4. After clamping, the operator starts the control motor 11, which drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 allows the sliding plate 13 to move. During this movement, cleaning fluid is sprayed onto the surface of the circuit board body 6 through multiple nozzles 14, and then the surface of the circuit board body 6 is cleaned by the cleaning plate 7. This eliminates the need for manual cleaning, greatly increasing cleaning efficiency and preventing dust from re-adheding after manual cleaning and re-fixing. This makes the entire process more efficient. The addition saves time and effort, and during the movement of the slide plate 13, the meshing of the spur gear 19 and the rack 20 can drive the rotating shaft 17 to rotate. The rotating shaft 17 transmits power to one of the rotating shafts 16 through the pulley assembly 18. The rotating shafts 16 rotate through the meshing of adjacent spur gears 21. Some of the rotating shafts 16 have a fan 22 fixedly installed at one end, so that the slide plate 13 can drive the fan 22 to blow air on the surface of the circuit board during the sliding process, eliminating the need for drying. This makes the cleaning process more continuous and reduces the overall time required for testing.
