Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a low-vibration detection platform device based on a double gantry structure. Background Technology

[0002] In the fields of semiconductor manufacturing and PCBA surface mount device soldering inspection, inspection platforms are key equipment for ensuring product quality and production efficiency. However, traditional inspection platforms mostly adopt a square tube structure, which has many defects and shortcomings, making it difficult to meet the inspection requirements of high precision, high speed, and high stability. Specifically:

[0003] 1) Limited accuracy: Due to insufficient material rigidity, the square tube structure cannot meet the requirements of high-precision testing. During long-term use, the testing accuracy will gradually decrease due to the elastic deformation and fatigue of the material.

[0004] 2) Effect of welding stress: During the welding process, the square tube frame is prone to internal stress due to uneven heating, which can lead to deformation during long-term use and further reduce the accuracy of inspection.

[0005] 3) Hollow structure noise amplification: The square tube has a hollow structure, which will generate greater vibration and noise when moving at high speed, affecting the stability and reliability of the test results.

[0006] Based on the above problems, traditional square tube structure inspection platforms cannot be applied to high-precision inspection fields, which limits their application scope in semiconductor manufacturing and PCBA surface mount device soldering inspection. Therefore, developing an inspection platform with high rigidity, low vibration, low noise and the ability to maintain high precision for a long time has become an urgent need in the industry.
