[0002] MOS devices, or metal-oxide-semiconductor field-effect transistors (MOSFETs), are among the most widely used transistors in modern electronics. They have advantages such as high input impedance, low noise, low power consumption, and ease of integration, and are widely used in various electronic circuits, such as switching circuits, amplifier circuits, and power management.

[0003] Multi-MOS device PCB products typically have a high degree of integration, enabling complex circuit functions to be implemented in a small space.

[0004] Currently, PCB self-inspection is a crucial step in ensuring PCB quality and performance. It typically involves using multimeters, oscilloscopes, microscopes, short-circuit location analyzers, and other equipment. During the inspection process, workers need to fix the PCB on the workbench using clamping devices before inspection. This process is cumbersome and inefficient. Therefore, it is necessary to design a high-speed self-inspection device for PCBs with multiple MOS devices. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed self-testing device for multi-MOS device PCB finished products that is simple to operate and improves testing efficiency.

The detection base has a rectangular motion groove on its surface, and the receiving base is located inside the motion groove. An X-axis motion guide and a Y-axis motion guide for controlling the movement of the receiving base are installed on the inner sidewall of the motion groove. Multiple receiving slots for placing PCB finished products are evenly opened on the upper surface of the receiving base. A suction cup is fixedly installed at the bottom of the receiving slot. A vertical guide rail is fixedly installed at one end of the upper part of the detection base, and a lifting plate is slidably installed on one side of the vertical guide rail. Multiple detection heads are evenly fixedly installed on the lower surface of the lifting plate.

[0007] Preferably, one end of the receiving base has a groove, and a cylinder is fixedly installed in the groove. The cylinder is connected to multiple suction cups through an air pipe.

[0008] Preferably, the lower part of the receiving base is provided with a Y-axis threaded hole that passes through the front and rear sides, and the lower part of the receiving base is provided with an X-axis threaded hole that passes through both sides. The threaded shafts of the lead screw motors on the X-axis motion guide rail and the Y-axis motion guide rail are respectively connected to the X-axis threaded hole and the Y-axis threaded hole.

[0009] Preferably, one end of the lifting plate is provided with an integral T-shaped sliding plate, and a vertical groove is opened on one side of the vertical guide rail. The T-shaped sliding plate is slidably installed in the groove. A threaded hole is opened in the middle of the T-shaped sliding plate. Another lead screw motor is installed at the bottom of the groove. The threaded shaft of the lead screw motor is connected to the threaded hole of the T-shaped sliding plate.
