Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing testing equipment technology, and in particular to a rotatable visual positioning SPI sorting device. Background Technology

[0002] In existing technologies, visual positioning SPI sorting equipment often suffers from limited detection range when inspecting printed circuit boards (PCBs). Its visual inspection head is typically fixed at a fixed angle or has a small range of adjustment, making it difficult to comprehensively cover different areas of the PCB. This leads to the easy omission of solder paste defects in some locations, affecting the integrity and accuracy of the inspection data. Furthermore, the clamping mechanism of existing equipment lacks flexibility for PCBs of different sizes, often only adapting to specific workpiece specifications. The stability during clamping is also poor, easily resulting in workpiece displacement, which in turn affects inspection accuracy. In addition, the clamping force lacks effective monitoring and control, easily causing damage to the PCB due to excessive pressure or loosening of the workpiece due to insufficient pressure. Regarding the drive and control of the equipment, traditional equipment often uses ordinary motors as power sources, which have low operational stability and control precision, making it difficult to meet the high-requirement demands for equipment operating accuracy and response speed in demanding industrial applications. This limits overall inspection efficiency and reliability, failing to balance functionality and ease of operation, causing considerable inconvenience to users.

[0003] Therefore, this invention proposes a rotatable visual positioning SPI sorting device to solve the above problems.
