Description

Technical Field

[0001] This utility model relates to the field of circuit board testing, and more specifically, to a circuit board testing bench. Background Technology

[0002] The circuit board testing system is designed based on a PC-based data acquisition and analysis system. Professional fixture design and material selection ensure system safety.

[0003] The utility model patent with authorization announcement number CN218412651U belongs to the field of circuit board testing platform technology and discloses a circuit board flipping device for a circuit board testing platform. It includes a testing platform body, a support platform, and a telescopic assembly. The top of the testing platform body has a storage slot, and the outer surface of the telescopic assembly cooperates with the interior of the storage slot. The telescopic assembly is movably connected to the support platform, and buffer components are used at the four corners of the bottom of the support platform. This utility model, by using the test platform body, support platform, telescopic assembly, storage slot, and buffer components in a coordinated manner, enables the support platform to be raised using the telescopic assembly when flipping is needed, then flipped. After flipping, it is lowered back to its original height, and the buffer components provide cushioning, solving the problem of existing devices being unable to flip. This circuit board flipping device for a circuit board testing platform has the advantage of good flipping performance.

[0004] In the above-disclosed structure, circuit board testing is performed by connecting a support platform and a telescopic component to the test bench body. However, it lacks a hinged U-shaped mounting bracket to install the positioning plate, which is not conducive to the assembly and alignment adjustment, cannot adaptably clamp and position the circuit board, is prone to interference, and is not convenient for quick flipping and adjusting the circuit board. It is also not conducive to double-sided testing and has poor adaptability, which needs to be improved. Utility Model Content

By hinged to a U-shaped mounting bracket on the support platform and combined with an adjusting screw to install a positioning plate, it can be assembled and positioned in combination. This facilitates the adjustment of the spacing to clamp and position the circuit board, ensuring stability. Furthermore, after hinged adjustment, it can be rotated to flip the circuit board for double-sided testing. It has high adaptability, is easy to assemble and position, and is convenient to adjust and use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A circuit board testing platform includes a support platform. A test chamber is fixedly mounted on one end of the upper surface of the support platform.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 and Figure 4A circuit board test bench includes a support platform 1. A test housing 11 is fixedly mounted on one end of the upper surface of the support platform 1. Hinges 12 are fixedly connected to both sides of the support platform 1. A U-shaped mounting bracket 13 is hinged to one side of the hinge 12. The U-shaped mounting bracket 13 is mounted by hinges 12, allowing for combination, connection, positioning, and rotation adjustment, thus facilitating operation according to testing needs and providing high adaptability. Adjusting screws 14 are threaded onto both sides of the U-shaped mounting bracket 13, with a fixed end rotatably mounted on one end of each adjusting screw 14. Positioning plate 15 is slidably mounted on the upper surface of support platform 1. One side surface of positioning plate 15 has a positioning slot 16. Protective strips 17 are fixedly connected to both sides of the inside of the positioning slot 16. These strips are engaged with the two ends of the circuit board via the slot 16, and the protective strips 17 provide pressure protection to prevent damage. Then, rotating the adjusting screw 14 pushes the positioning plate 15, allowing it to be clamped and positioned from both ends, thus assisting in positioning and facilitating installation into the U-shaped mounting bracket 13. This allows for positioning testing and convenient flipping for double-sided inspection. With high adaptability, both ends of the positioning plate 15 are fixedly connected to limit blocks 18. One side of the limit block 18 is provided with a limit groove 19. A limit plate 2 is slidably installed on one side of the U-shaped mounting bracket 13. The limit plate 2 is slidably engaged with the inner side of the limit groove 19. The limit plate 2 is tightly connected to one end of the positioning plate 15. The limit blocks 18 are symmetrically distributed at both ends of the positioning plate 15. They are engaged with the limit groove 19 by the limit plate 12. They can be combined and connected to the inside of the limit blocks 18, thereby providing auxiliary positioning for the two positioning plates 15. This design ensures the stability of the circuit board installation and positioning, allowing testing of circuits and components on one side. When operation on the back side is required, the U-shaped mounting bracket 13 can be manually pushed to rotate around the hinge seat 12, thereby removing the positioning plate 15 from the surface of the support platform 1. Then, the positioning plate 15 can be rotated 180 degrees around the end of the adjusting screw 14 to flip the circuit board over. Finally, the U-shaped mounting bracket 13 can be reattached to the surface of the support platform 1 for repositioning and testing. This design facilitates adjustment and has high adaptability.

[0027] Please see Figure 2 and Figure 3 The U-shaped mounting bracket 13 has combination grooves 21 on both sides inside. The combination grooves 21 are located at both ends of the limiting plate 2. A guide block 22 is slidably installed at one end of the combination groove 21. The guide block 22 is fixedly connected to one end of the limiting plate 2. A clamping spring 23 is fixedly connected to one side of the guide block 22. The clamping spring 23 is slidably installed inside the combination groove 21. The guide block and the clamping spring are connected by the combination groove, which can be combined for clamping and support to ensure the stability of the limiting plate in the locking position. It can also be manually pushed for adjustment to avoid interference. It has high adaptability. The clamping spring 23 can clamp the guide block 22 to assist in clamping the limiting plate 2, thereby ensuring the stability of the positioning plate 15.

[0028] Please see Figure 1 and Figure 5 Both ends of the U-shaped mounting bracket 13 are fixedly connected to buffer rods 24. The buffer rods 24 are supported and connected to the upper surface of the support platform 1. The lower surface of the buffer rods 24 is fixedly connected to a buffer head 25. The buffer head 25 is tightly connected to the upper surface of the support platform 1. One end of the buffer head 25 is fixedly connected to a spherical rubber head 26. The spherical rubber head 26 is located at the bottom of the buffer rod 24. By connecting the buffer head and the spherical rubber head through the buffer rod, the U-shaped mounting bracket can be buffered and supported, making it easy to flip and adjust, and ensuring safety and stability.
