What is the role of machine vision inspection system in mask production?

Today, automatic vision inspection system manufacturer Rihong Intelligence will introduce you the role of machine vision inspection system in vision system companies. The function of machine vision inspection system.

Importance of machine vision inspection system for mask quality inspection.

How to pursue efficiency, mass production and control the quality of masks in a short period of time, automation has become a very critical point in the production of masks.

Masks in the production and development process management will continue to appear in the ear rope off, rows of teeth asymmetry, stains, breakage and other defects, the emergence of these problems defects a serious social impact on the quality of masks, reduce the performance of masks or can not pass the use. It is difficult for the human eye to visually inspect the quality aspects of the product more accurately and consistently.

With automated production, quality control can be combined with machine vision to assist in checking mask defect detection. automated inspection system provides high-speed, high-precision, long-term, stable and repetitive work, which greatly reduces the error rate compared to manual inspection, and also avoids the disadvantage of elastic fatigue of the human eye inspection, which improves the quality of the product and the speed of production.

The automatic visual inspection system makes the automation process of mask manufacturing more perfect.

In order to avoid any defects or imperfections in mask production, some manufacturers have added defect detection, which reduces the error rate. Machine vision inspection equipment speeds up the final inspection phase of the mask manufacturing process and increases efficiency. In this process, the industrial camera can accurately and quickly capture the most realistic image data, and together with the back-end analysis software, it can help the production line staff to make the most effective judgment in the shortest possible time, reducing labor costs and the chance of mask contamination in the production process.

Key points of finished mask inspection in machine vision inspection system

1, mask size and whether it can meet the national standard (within plus or minus one centimeter)

By measuring at the back end, it is possible to check whether the length and width are consistent with normal values.

2. Logo detection

Combined with image analysis, the correctness, displacement or defects of the mask logo text can be verified.

3. Mask surface

Through the image data, it is easy to determine whether there are defects, dirt or stains on the surface and sides of the mask.

4、Mask perforations and overlap using the pressure line (no pressure line work in the middle whether to carry out leveling; both sides of a total of four rows of perforations)

Through the image can automatically determine whether the mask pressure line is offset or not, also can judge the number of side holes to measure whether this product meets the specifications.

5. Earwire length and solder joint position

The image is captured by the camera and measured by the back-end software to determine if the length is within standard values.

6. Nose piece position and length

The nose piece is an important protective design element of the mask. Pressing on the nose piece after putting on a mask allows the mask to be tightly fitted, eliminating the intrusion of such bacteria and dust, and preventing the splashing of saliva. Through these vision technology inspections, the length of the nose piece can be clearly measured, and it is also possible to confirm whether you are off-set or have any other company defects.

Machine vision inspection equipment power mask quality control, improve mask production efficiency, save labor costs, but also let us use the mask more assured!
