AI Technical Summary

Technical Problem

Existing PCB resin plugging detection devices cannot easily adjust the board position to accommodate the differences in the location of resin plugging defects on different boards, resulting in reduced applicability of the device.

Method used

A detection device comprising a connecting frame, an adjustment mechanism, and a positioning mechanism was designed. Through a sliding rod, a sliding plate, a rotating sleeve, a worm gear mechanism, and a connecting rod structure, the position of the PCB board is adjusted and fixed to ensure the accuracy of the detection.

Benefits of technology

It enables the detection of resin plugs at different locations on PCB boards, preventing board displacement, improving detection accuracy and device applicability, and is simple and convenient to use.

Abstract

This utility model discloses a testing device applied to the PCB resin plugging process, belonging to the technical field of PCB board testing devices. The utility model includes a connecting frame, with the main body of the testing instrument slidably connected to the inner wall of the connecting frame. An adjustment mechanism is provided on the outer wall of the connecting frame, and the adjustment mechanism includes several sliding rods. A sliding plate is slidably connected to the outer wall of each sliding rod, and a rotating rod sleeve is rotatably connected to the inner wall of the sliding plate. A limiting groove is formed on the inner wall of the rotating rod sleeve. By setting the sliding plate on the sliding rod, when the equipment needs to be used, the worm gear is rotated. The rotation of the worm gear drives the worm wheel to rotate, causing the rotating rod sleeve to rotate. The rotation of the rotating rod sleeve causes the fixed shaft to move along the trajectory of the arc groove within the arc groove, thereby causing the rotating rod to move. The limiting groove can limit the movement trajectory of the fixed shaft, achieving the ability to adjust the position of the testing equipment and the fixed PCB board during PCB board testing.
