According to the system processing information, the conveyor belt 10 transmits the word logo to the corresponding workstation. The robots at different workstations process the word logo respectively, including cutting off the excess material of the word logo blank to generate the word logo, and then pasting double-sided tape on the back of the word logo, and covering both sides of the word logo pasted with double-sided tape with protective film.

[0038] In the above embodiment, the robot selects the word logo blank from the pallet according to the system processing information, then cuts off the excess material of the word logo blank, and then attaches double-sided tape and a protective film to the word logo. After the word logo is electroplated, it can be fully automatically assembled unmanned until the lower limit of the finished product. Each workstation can complete the work independently and cooperate with each other to improve production efficiency and coordinate high-speed production of the entire production line.

According to the program requirements, the blank that meets the requirements is grabbed from the loading tray at a fixed point. When the blank at each position of the loading tray is placed on the loading tray, the employee needs to input the relevant information of the blank. The second cylinder drives the bottom clamp 32 to move up, abutting the clamping rod 31 of the word mark, and its corresponding elastic member generates potential energy so that the clamping rod 31 and the bottom clamp 32 are contoured and locked to fix the word mark blank. The remaining material is located on the back of the word mark.
