The identification card printer is a device for printing identification cards as the name implies. In daily work and life, with the popularization and application of smart cards, various chest cards or certificate cards and business cards printed with high-quality photos are products thereof. The key of certificate card printing is the quality of output, and although the photo printing quality of the current ink-jet printer is quite good, the certificate card printing is usually performed by a certificate card printer adopting the thermal sublimation principle.

Most of cards need double-sided printing, namely, after the front side is printed, the cards are turned to the back side to be printed. The existing card printer can only print one side at a time, so the card needs to be manually turned and put into the printer to print again. And the printer that is equipped with the upset module, after having printed the front, the printer can overturn the card automatically, carries out the back and prints. Double-sided printing can be realized by one-time operation, and card manufacturing efficiency is greatly improved.

The assembly for realizing automatic turning is called a turning module and is used for turning over the card and moving the card. At the present stage, the position of the turnover module generally adopts a single detection mode to position the turnover position, so that the condition of the position of the card is obtained, and whether the card is turned over or not is judged. The positioning in this way is not accurate enough, and the function is single, and the position determination after multi-angle overturning of the existing overturning module can not be met. Moreover, the positioning mode and the overturning mode of the existing overturning module have more limitations, the overturning module is too dependent on the manufacturing precision and is easily influenced by installation deviation, whether the overturning module runs in place or not can not be accurately identified, the problems of easy failure and the like are caused, and the printing efficiency is influenced.
