Description

Technical Field

[0001] The utility model relates to the technical field of button processing, in particular to a button assembly system and button production equipment. Background Art

[0002] Snap buttons are a type of button, commonly known as snap buttons, spring buttons, and sewn buttons. They can be used in all kinds of clothing, luggage, handbags, shoes and hats, packaging and other products. Snap buttons include female buttons and male buttons, where the male button is made by stamping and riveting the first and second parts. In the button manufacturing industry, the existing button machines have a simple structure and a low degree of automation. They also require manual participation during the assembly process, which reduces production efficiency, and there are safety hazards in manual operation.

[0003] A Chinese patent with publication number CN107497945A and publication date 2017-12-22 discloses an I-shaped button riveting device and an I-shaped button multi-station assembly machine using the device. Although the patent can realize the automatic assembly of buttons and reduce the manual participation in the assembly work, the assembly machine of the patent has a low degree of automation and cannot automatically perform waste removal. During the assembly process, although the first sensor and the second sensor can detect whether there are twisted surfaces and gaskets in the button sleeve, the machine will stop every time the lack of twisted surfaces or gaskets is detected, and then manual screening is performed, which not only affects the working efficiency of the equipment, but also poses a safety hazard when manual operation.
