A visual inspection machine for increasing board loading speed

Abstract

The present application discloses an appearance inspection machine, which includes a hook part, the hook part includes a first hook part and a second hook part, and the first hook part and the second hook part The number is two; the conveying part includes a drawing area and a lower plate area; two of the first hook parts are arranged in the drawing area, and the two first hook parts are reciprocated as follows Movement: one pushes the circuit board forward to move forward in the image-taking area, and the other moves back; the two second shifting hook parts are arranged in the lower plate area, and the two first The two shifting hook parts perform reciprocating motions as follows: one pushes the circuit board forward to move forward in the lower plate area to the next area, and the other moves back. The structural design of the device can increase the moving speed of the circuit board on the conveying parts, improve energy efficiency, and further exert the production capacity of the visual inspection machine.

Description

technical field [0001] The present application relates to the technical field of circuit board appearance defect detection, in particular to an appearance inspection machine for increasing board loading speed. Background technique [0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board and printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it uses electronic printing It is made by technology, so it is called printed circuit board. The current PCB board mostly uses manual methods to detect whether each part of the PCB board can meet the design parameter requirements, the detection speed is slow, the detection accuracy is low, and it cannot meet the needs of rapid detection, resulting in The work efficiency is relatively low, which brings difficulties to the large-scale integrated production of enterprises. ...

AI Technical Summary

Problems solved by technology

[0005] First, when the image acquisition device is performing image acquisition, the light source is easily blocked by the hook device used to promote the movement of the circuit board, resulting in unclear and inaccurate image acquisition;

[0006] Second, when the hook device pushes the circuit board to be transported on the conveying device, it is prone to slipping, which causes the circuit board to be separated from the hook device, and the circuit board is pulled out of the track;

[0007] Third, when the hook device pushes a circuit board with a heavy weight, the hook device is prone to swing, resulting in unstable imaging of the circuit board and affecting the imaging quality;

[0008] Fourth, the movement speed of the hook device is very fast, and the weight of the hook device is relatively large, and it moves many times a day, resulting in a relatively large movement pressure on the entire hook device, which is prone to vibration and reduces the service life

[0009] Fifth, the energy efficiency of the toggle hook device can reach 800 pieces / hour at the fastest, which is low in energy efficiency and does not fully utilize the production capacity of the appearance inspection machine
