Mask visual inspection device produced by KN95 Mask Machine

In the traditional mask quality inspection link, it is necessary to inspect the welding ear straps of the mask or the front and back sides of the mask to ensure that the quality of the mask meets the production requirements. As a result, the mask needs to be turned over during the transmission process of the mask, to complete the data collection and detection. Affected by factors such as the cost of testing equipment and the contamination during the transmission of the light-transmitting belt, the accuracy of data detection cannot be guaranteed. So what is the mask visual inspection device produced by KN95 Mask Machine? Let's take a look at it next.

Design principle

The KN95 Mask Machine detection device mainly includes a frame, a conveying roller, a light source, a mask conveying track, a camera, etc. There are several groups of conveying rollers installed in the horizontal direction on the frame, and a mounting plate is arranged on the side of the conveying roller. A light source and a light-transmitting plate are installed between the adjacent two groups of conveying rollers. The light source is close to the mask conveying track, and a camera is arranged above the light source. The distance between the surface and the mask conveying track is controlled within 10 mm. The innovation of the KN95 Mask Making Machine testing device lies in the use of transfer rollers to transfer the masks. When the masks are located between two adjacent groups of transfer rollers, a camera is used to take pictures for inspection, which can be used for quality inspection and control during the mask production process. Effectively Reduce the reject rate of finished masks and improve production efficiency.

Device design ideas

The technical scheme of the KN95 Making Machine visual inspection device is analyzed in detail. The device mainly includes four components: conveying roller, light source, light-transmitting plate, and mounting plate. Install multiple groups of conveying rollers on the frame in a horizontal form, and install a light-transmitting plate between the adjacent two groups of conveying rollers to keep the surface of the light-transmitting plate flush with the mask conveying track, and control the height difference within 10 mm. Ensure that the mask is smoothly transferred to the next set of conveying rollers, and install the side of the light-transmitting plate on the mounting plate; when using the camera to take pictures of the reverse side of the mask, choose to install the light source above the light-transmitting plate and the mask conveying track; 

When the front image is used, there is no need to install a light-transmitting plate between the two sets of conveying rollers. It is only necessary to install the light source under the conveying track of the mask and install the mounting plate on the side of the conveying roller. Considering that the welding ear straps of the mask need to be tested, the welding points are usually located at the head and tail of the mask. 

Therefore, it should be ensured that the distance between the adjacent two groups of conveying rollers is greater than the length of the mask to ensure that the mask is driven by the conveying rollers. When the transfer rollers are assembled, the camera can capture an image of just one side of the mask. The new KN95 Making Machine detection device removes the original light-transmitting belt by connecting and combining the transmission roller and the light-transmitting plate, which can effectively reduce the probability of misjudgment caused by the dirty belt, effectively saving the production cost of masks, and do not need to be replaced repeatedly. Improves production efficiency and significantly improves the accuracy of inspection results.
