Abstract
Description
Technical Field
[0001] The invention relates to the technical field of die-cutting product detection, and in particular to a package die-cutting product detection device. Background Art
[0002] At present, in the field of die-cutting products, there are two types of product forms: sheet and roll. With the advancement and deepening of unmanned and automated needs in the industry, since roll-to-roll die-cutting products can better meet the use requirements of various types of automated equipment, the design forms of various sheet die-cutting products tend to be closer to the roll form.
[0003] The existing roll-to-roll die-cutting products have the following common problems in the production and use of die-cutting:
[0004] ① It is a common phenomenon that each die-cutting factory uses QC inspectors to inspect various die-cutting products. The inspection efficiency of personnel is slow and the quality stability is insufficient, especially for large and small size products, which are prone to missed inspections;
[0005] ② When personnel inspect the same type of products in coil form, they are prone to visual fatigue, which will increase the risk of missed inspections;
[0006] ③. When personnel check the roll-type die-cut products and remove the defective products, blank spaces will be formed in the roll material. Such blank spaces will cause problems such as equipment shutdown and alarm when the roll-type die-cut products are used in the next process, affecting the customer experience of the next process.
[0007] In order to improve and solve the problem of equipment alarm and shutdown when the next process is used, QC inspectors use manpower to add OK products to the blank positions of the roll material, which is prone to defects such as missing stickers and crooked stickers, with low efficiency and unable to fundamentally solve the problem of equipment alarm and shutdown when the next process is used.
[0008] How to solve the above-mentioned technical problems has become a technical problem that needs to be solved urgently in the industry. Summary of the invention
[0009] In order to at least solve the above technical problems, the purpose of the present invention is to provide a device for detecting die-cut products from a roll, which solves the problem of missed detection during manual detection of die-cut products.
