Technical Field

[0001] This utility model relates to the field of solder paste size detection, and more specifically, to a solder paste size detection device. Background Technology

[0002] Solder paste dimension inspection devices are primarily used to inspect the thickness and dimensions of solder paste printed during the SMT (Surface Mount Technology) production process. Solder paste is a critical material used to mount electronic components onto PCBs (Printed Circuit Boards), and its dimensions and quality directly affect the soldering quality and the performance of electronic components. Therefore, precise control of solder paste dimensions is crucial. By using dimension inspection devices, the dimensions of the produced solder paste can be checked to ensure the reliability of each solder joint.

[0003] Currently, most solder paste size detection devices have the following problems:

[0004] I. In existing solder paste size detection devices, most of the components to be detected are placed on a workbench with a fixed height. The size of the solder paste material varies, and the distance between it and the detection device varies. Being too far or too close can easily affect the detection effect, and it is inconvenient to adjust the detection distance and height according to the detection situation.

[0005] Second, existing solder paste size detection devices are mostly connected and fixed by welding or multiple bolts in order to improve the stability of the detection instruments. However, after long-term use, the detection instruments need to be disassembled for inspection and maintenance. Disassembly requires cutting the soldered parts or removing multiple bolts, which is troublesome and inconvenient for convenient installation and disassembly of the detection instruments.

[0006] Therefore, we have made improvements to this by proposing a solder paste size detection device. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in adjusting the detection distance and height according to the detection situation, and the inconvenience in conveniently installing and disassembling the detection instruments.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. Equipped with guide plates; when adjusting the working table's height, the servo motor can be activated to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the connecting plates on both sides to move outward simultaneously. The connecting plates can drive the guide plates to move simultaneously.

When the connecting shaft drives the gear to rotate, the gear can drive the internal gear ring to rotate. The internal gear ring can drive multiple connected gears to rotate simultaneously. When the connecting shaft on the gear rotates, the limiting bracket on the connecting shaft can disengage from the positioning bracket. The positioning bracket can be removed from the mounting box without obstruction, allowing the 3D scanning laser on the positioning bracket to be disassembled for inspection and maintenance.
