Push pin device of optical detector

Abstract

A push pin device of an optical detector is characterized in that a bottom plate (6) is arranged below a clamp body (3), guide rods (4) are symmetrically arranged on the lower surface of the bottom plate (6) and support the bottom of the optical detector, the lower surface of the bottom plate (6) is also contacted with a cylinder (5), and a push pin (1) which is fixed on the upper surface of the bottom plate (6) is contacted with the bottom surface of the PCB (2) of the clamp body (3). The benefits are as follows: the push pin device can push against the sinking position of the PCB in a targeted way, thus leading the whole PCB to be at the same plane, so as to overcome the defect that as the middle sinking of the PCB causes welding spots on the PCB to be indistinct or not to be observed integrally, the detection result is influenced, when the optical detector of the current market is adopted to detect the PCB.

Description

technical field [0001] The invention relates to a thimble device, in particular to a thimble device used in an optical detector. Background technique [0002] The optical detector is a device that detects the solder joints of the PCB board after solder joint welding. The PCB board usually needs to detect the solder joints after welding, such as: detecting whether the solder joints are round and complete, or whether there is empty welding , Virtual welding, continuous welding and other phenomena. When the PCB board is sent under the camera of the optical detector, it is observed through the lens of the camera or microscope, and then the computer analyzes the soldering condition of the solder joints on the PCB board. Usually, the fixing of the PCB board is to fix the PCB board through the clamps corresponding to the two ends of the clamp body, and clamp the PCB board on the steps at both ends of the clamp body through the clamps, but if the size of the PCB board is relatively...

AI Technical Summary

Problems solved by technology

The thimble device can withstand the depression of the PCB board in a targeted manner, so that the entire PCB board is on the same plane, so as to solve the problem that the PCB board is caused by the depression in the center of the PCB board when the optical detector on the market detects the PCB board. Defects that the solder joints on the surface are blurred or cannot be completely observed, thus affecting the inspection results
