Feeding device of printed circuit board hole detection machine

Abstract

The invention relates to the technical field of circuit board detection, in particular to a feeding device of a printed circuit board hole detection machine. The feeding device of the printed circuitboard hole detection machine comprises a working cabinet, a limiting mechanism and a feeding mechanism. The limiting mechanism is arranged on the top of the working cabinet. The feeding mechanism comprises a supporting frame and a material transfer part. The limiting mechanism comprises two limiting parts. Each limiting part comprises a limiting plate and two adjusting bolts. The material transferpart comprises a lifting assembly and an absorption assembly, wherein the absorption assembly is installed at the bottom of the lifting assembly. The absorption assembly comprises an absorption plateand multiple absorption heads. A driving motor is arranged on the top of the absorption plate and is used for driving the multiple absorption heads to surround the absorption plate to conduct the circular motion around the normal which passes through the center point of the absorption plate. By the adoption of the full-automatic feeding mode, the manpower output in the feeding process is reduced,the working efficiency of circuit board feeding is improved, and the accuracy of the circuit board feeding position is improved.

Description

technical field [0001] The invention relates to the technical field of detecting circuit boards, in particular to a feeding device for a printed circuit board hole inspection machine. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are based on insulating boards, cut to a certain size, with at least one conductive pattern attached to them, and holes (such as component holes, fastening holes, metallized holes, etc.) , used to replace the chassis of the previous installation of electronic components, and realize the interconnection between electronic components. [0003] At present, for the visual inspection of printed circuit boards, most manufacturers use manual visual inspection, but manual inspection has its own defects, so the final quality control of printed circuit boards is quite difficult. In the industry, The need for fast, highly discriminative, and highly automated devices for visual inspection of printed circuit boards ...

AI Technical Summary

Problems solved by technology

[0003] At present, for the visual inspection of printed circuit boards, most manufacturers use manual visual inspection, but manual inspection has its own defects, so the final quality control of printed circuit boards is quite difficult. In the industry, The need for rapid, highly discriminative, and highly automated devices for printed circuit board visual inspection is increasing

Under such circumstances, there is a printed circuit board hole inspection machine. The feeding method of the existing printed circuit board hole inspection machine is also a manual feeding method. Such a feeding method is slow and there will be feeding The inaccuracy of the position will affect the detection results of the hole inspection machine
