Description

Technical Field

[0001] This utility model relates to the field of testing and experimental platforms, and in particular to a steel mesh testing and experimental platform. Background Technology

[0002] A stencil is a tool used in the manufacturing process of printed circuit boards (PCBs). It is mainly used to create circuit patterns on a substrate. A stencil is a thin sheet made of a metal material (usually stainless steel) with a precise pattern of holes on its surface. These holes are precisely designed to apply solder paste or other materials to the circuit board. The use of a stencil ensures that each solder joint receives the appropriate amount of solder paste, thereby improving the soldering quality of the circuit board. The consistency of the stencil avoids human error and ensures that the amount of solder paste on each PCB is uniform, thereby reducing quality fluctuations after reflow soldering. This is especially important for automotive electronics and medical devices.

[0003] In practical applications, steel mesh often needs to be tested for tension. The tension test of steel mesh usually involves testing 5 points: one in the middle and 4 points around the perimeter of the steel mesh. If the tension at any of the 5 points is less than 38N, it is considered unqualified. However, existing testing equipment can usually only perform limit fixation and tension testing on a specific type of steel mesh and cannot measure steel mesh of different sizes, which makes it difficult to meet the actual use requirements.

[0004] Therefore, those skilled in the art have provided a stencil testing platform to address the problems mentioned in the background section. Utility Model Content

[0025] Specifically, the upper end of the main body 1 has sliding grooves 8 on its front and rear sides. During use, the sliding grooves 8 allow the moving block 3 to slide on the upper end of the main body 1. Threaded plates 2 are fixed to both sides of the lower end face of the moving block 3. The threaded plates 2 can be connected to the moving module 7. When the moving module 7 is activated, the threaded plates 2 can move, and the moving block 3 can move as well. Two air inlets 4 are installed on the upper end face of the moving block 3. The air inlets 4 can be connected to an external air pump, allowing gas to be transmitted into the airbag 6, enabling the airbag 6 to inflate. When used on the test bench, the steel mesh needs to be placed on the top of the main body 1. After the steel mesh is placed on the top of the main body 1, the moving module 7 is activated, which allows the threaded plate 2 to drive the moving block 3 to move. When the moving module 7 moves the moving block 3 to both sides of the steel mesh, the external air pump and the air inlet 4 are connected. The air inlet 4 can transmit gas to the inside of the airbag 6. After the airbag 6 is deployed, it can squeeze both sides of the steel mesh. When the moving block 3 moves, the pressing plate 5 can press the top of the steel mesh. The airbag 6 and the pressing plate 5 can keep the steel mesh stable on the top of the main body 1.

[0027] Specifically, the main structure of the mobile module 7 includes a placement box 701, with a support plate 702 installed on the inner bottom surface of the placement box 701. The upper end of the support plate 702 can fix the rotating motor 703. The output end of the rotating motor 703 is provided with two first sprockets 705. When the rotating motor 703 is started, the two first sprockets 705 can rotate. The rear end face of the placement box 701 is fixed to the protective box 704. Bidirectional threaded shafts 708 are rotatably provided on both sides of the rear end of the protective box 704. The outer surfaces of the two bidirectional threaded shafts 708 are fixed with second sprockets 706. The two second sprockets 706 can be connected to the two first sprockets 705 through a chain 707. When the rotating motor 703 is started, the first sprockets 705 can drive the second sprockets 706 to rotate through the chain 707. When the second sprockets 706 rotate, the bidirectional threaded shafts 708 can rotate. The outer surface of the bidirectional threaded shafts 708 is connected to the threaded plate 2. When the bidirectional threaded shafts 708 rotate, the threaded plate 2 can move.

The air inlets 4 can transmit gas into the airbag 6, allowing the airbag 6 to inflate and unfold. When the threaded plate 2 moves, the moving block 3 can be moved. When the moving module 7 moves the moving block 3 to both sides of the steel mesh, the air pump is started to transmit gas into the airbag 6. After the airbag 6 unfolds, it can squeeze both sides of the steel mesh, allowing the steel mesh to remain stable at the top of the main body.

[0029] The main structure of the moving module 7 includes a placement box 701. The interior of the placement box 701 is fixed by a support plate 702 and a rotating motor 703. The output end of the rotating motor 703 is provided with two first sprockets 705. The two first sprockets 705 are connected to two second sprockets 706 by a chain 707. The two second sprockets 706 are equipped with bidirectional threaded shafts 708. When the rotating motor 703 is started, the first sprockets 705 can drive the second sprockets 706 to rotate through the chain 707. When the second sprockets 706 rotate, the bidirectional threaded shafts 708 can rotate. The outer surface of the bidirectional threaded shafts 708 is connected to the threaded plate 2. When the bidirectional threaded shafts 708 rotate, the threaded plate 2 can rotate. When the threaded plate 2 moves, the moving block 3 can move.
