Automatic feeding structure, appearance detection device and mask appearance detection device and method

Abstract

The application relates to an automatic feeding structure, an appearance detection device and a mask appearance detection device and method. The automatic feeding structure comprises a rack, a controller and at least one group of acquisition structures; an air cylinder and a second acquisition piece are respectively fixed to the rack; a first acquisition piece and a third acquisition piece are respectively in driving connection with the air cylinder; the first acquisition piece and the third acquisition piece are arranged in a linkage manner, and the moving direction of the first acquisition piece is opposite to that of the third acquisition piece; and the controller controls the positions of the first acquisition piece and the third acquisition piece through the air cylinder and respectively controls the acquisition actions of the first acquisition piece, the second acquisition piece and the third acquisition piece. Forepart production equipment is linked up, so that the manual handling process is saved, and a product such as a mask that the forepart production equipment produces is directly conveyed out after being transferred; and meanwhile, the forepart production equipment islinked up to continue to acquire a next product, so that the automatic feeding efficiency is improved, the structure is simple, and the cost of implementation is low. The automatic feeding structure,the appearance detection device and the mask appearance detection device and method are especially applicable to production bays with limited space.

Description

technical field [0001] The application relates to the field of industrial visual inspection, in particular to an automatic feeding structure, an appearance inspection device, a mask appearance inspection device and a method. Background technique [0002] At present, the vast majority of KN95 masks on the market use manual visual appearance inspection, and a small part use automated equipment for visual appearance inspection. The efficiency of manual inspection is low and the accuracy is difficult to guarantee. The traditional automatic KN95 mask detection equipment adopts machine vision technology to take pictures through industrial cameras, analyze and process the images, and judge whether the currently photographed products are qualified according to the set parameters, and then pass the rejecting device on the equipment to disqualify the unqualified products. remove. [0003] The Chinese patent with the publication number CN107014822A discloses a non-woven mask defect vi...

Problems solved by technology

[0006] However, the traditional technology loads materials offline, so it cannot be directly connected to the front-end KN95 mask production line. The traditional equipment uses the product storage device installed at the front end to stack the finished KN95 products manually, and then place them on the In the storage device, the storage device can automatically transfer the product piece by piece to the testing station for testing

Therefore, the traditional automatic KN95 mask testing equipment cannot be automatically connected with the front-end production equipment, and manual sorting and handling of products is required.

[0007] Moreover, the traditional automated KN95 mask testing equipment uses multiple stations to visually detect the product, increasing the number of action steps, reducing the detection efficiency, and the hardware cost is high

[0008] In addition, the average production rate of the KN95 mask production equipment in the front section is 50 pieces / minute, and the rate range is 40-60 pieces / minute. The detection efficiency of the traditional automatic KN95 mask testing equipment is 45 pieces / minute

Therefore, the traditional automated KN95 mask testing equipment needs to limit the production efficiency of the front-end production equipment, that is, it can only be used at a reduced speed in the front-end, resulting in reduced production efficiency
