Abstract

The invention provides an edge rolling processing technology. The edge rolling processing technology specifically includes the following steps that S1, dispensing is conducted on case covers through a first dispensing machine, and the case covers and case bodies are assembled; S2, edge rolling and sealing are conducted on the joints of the case covers and the case bodies to form closed box bodies; S3, gas tightness detection is conducted on the box bodies, and the qualified box bodies are screened out; and S4, code spraying is conducted on the qualified box bodies. According to the edge rolling processing technology, by conducting dispensing on the case covers through the first dispensing machine before the case covers and the case bodies are assembled, connection between the case covers and the case bodies can be tighter; then, edge rolling and sealing are conducted on the joints of the case covers and the case bodies to form the box bodies, the gas tightness of the box bodies is enhanced, and therefore the product yield is increased, and defective products poor in gas tightness are reduced; and by conducting the gas tightness detection on the closed box bodies, screening of the box bodies is completed, the unqualified box bodies are further removed, and code spraying is conducted on the qualified box bodies.

Description

technical field [0001] The invention relates to the technical field of hemming processing, in particular to a hemming processing technology. Background technique [0002] Hemming processing is a common processing method. The connection between the box cover and the box body is sealed by hemming processing to form a sealed box body. However, the hemming process currently on the market cannot guarantee a good seal between the box cover and the box body, and there are many defective products. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to provide a hemming process to solve the problem of many defective products in the existing hemming process, improve the sealing between the box cover and the box body, and improve the yield of products. [0005] (2) Technical solution [0006] In order to solve the above technical problems, the present invention provides a hemming process, which specifically inclu...
