Visual detection system in mask folding process and detection method thereof

Abstract

The invention relates to a visual inspection system in a mask folding process and an inspection method of the visual inspection system. The visual inspection system comprises a support, a first ultrasonic welding device, a second ultrasonic welding device and a pair of first hydraulic pressing devices, and the first ultrasonic welding device cuts folding seams at equal intervals along the center line of mask cloth; a folding mechanism for turning over and folding the mask cloth is arranged between the pair of first hydraulic pressing devices, and visual detection instruments for detecting themask cloth are distributed above the folding mechanism; the folding mechanism enables the folding seams in the mask cloth to be aligned with the visual detection instrument so as to shoot and detect the mask cloth through the visual detection instrument. The mask cloth is detected through cooperation of the folding mechanism and the visual detection instrument, production automation is achieved, and the defect that production equipment is high in cost is overcome; whether the mask cloth can be folded neatly or not is detected by comparing the tracks of the folding seams through a computer, andthe problem that the whole batch of masks are scrapped due to the fact that the masks are not folded in place at a time in the mask production process is solved.

Description

technical field [0001] The invention relates to mask production and processing equipment, in particular to a visual inspection system and a detection method in the mask folding process. Background technique [0002] As a technology that uses machines instead of human eyes to make various measurements and judgments, visual inspection technology can play a huge role in the process of mechanical processing and production. [0003] The traditional folding process of mask production is mainly to continuously improve the production pass rate of masks by improving the precision of production equipment and perfecting the production process, which leads to high production equipment costs, time-consuming and labor-intensive production process, and the final product pass rate is not optimistic. In order to solve the problem that the entire batch of masks may be scrapped due to an incomplete folding that may occur during the mask production process, a visual inspection system and detect...

Problems solved by technology

[0003] The traditional folding process of mask production is mainly to continuously improve the production pass rate of masks by improving the precision of production equipment and perfecting the production process, which leads to high production equipment costs, time-consuming and labor-intensive production process, and the final product pass rate is not optimistic.

In order to solve the problem that the entire batch of masks may be scrapped due to an incomplete folding that may occur during the mask production process, a visual inspection system and detection method during the mask folding process was designed.
