Problems solved by technology

The negative pressure box method requires a relatively large structural space, and the tension provided is unstable, which can easily lead to position deviation during the stepping process of the flexible carrier; the gravity roller method has constant tension, but in the high-speed bonding and stepping process, the gravity roller The response time is relatively slow. During the stepping process of the flexible carrier, the gravity roller cannot be positioned, which will cause the positioning deviation of the flexible carrier; the motor drives the gravity roller method, the structural space is relatively large, and the motor response time is relatively slow during high-speed motion, which cannot be achieved. Controlled synchronously with the bonding process and therefore also has significant limitations

Abstract

The invention provides a tension maintaining system, comprising: a motion platform and a flexible carrier transmission device; the flexible carrier transmission device includes a moving guide wheel assembly for guiding the flexible carrier, and the mobile guide wheel assembly is arranged on the flexible carrier transmission device The side close to the moving platform is used for synchronous lifting movement with the moving platform, and keeps the tension of the flexible carrier between the moving platform and the moving guide wheel assembly constant. In the present invention, the moving guide wheel follows the motion platform to carry out the lifting movement synchronously to prevent the tension of the flexible carrier from changing; the present invention also uses the locking mechanism to lock the moving guide wheel during the transmission of the flexible carrier to prevent its displacement during the transmission process. Maintain the tension of the flexible carrier during the transmission process; the invention also applies a certain pressure to the moving guide wheel through the spring structure to ensure the pressure exerted by the moving guide wheel on the flexible carrier and maintain the tension of the flexible carrier during the bonding process.

Description

technical field [0001] The invention relates to the field of electronic label packaging, in particular to a tension maintaining system. Background technique [0002] In modern technology, with the increasing application of electronic tags, the cost of electronic tags is getting lower and lower, and the requirements for the efficiency of chip packaging and testing equipment are getting higher and higher. Bonding on the flexible carrier and fast stepping of the flexible carrier after bonding is one of the main processes of chip packaging and testing equipment. During this process, the flexible carrier is required to maintain a constant tension, otherwise it will cause the flexible carrier to step Inaccurate positioning, position offset and other problems. [0003] In high-speed bonding and stepping processes, the flexible carrier is required to maintain a constant tension. The existing tension control methods include negative pressure box, gravity roller, and motor-driven gra...
