Description

Automatic film bonding equipment and automatic film bonding method using the same

The present invention relates to an automatic film bonding equipment and an automatic film bonding method using the same.

The conventional film splicing device must assign manpower to keep an eye on the stock of the film material, and rely on experience to judge whether the film material needs to be replaced. In addition, before the film material is about to be used up, the production line must be manually stopped, and then the new film material must be manually replaced. The production line can be restarted for production after the old film material and the new film material are joined together. Furthermore, in the process of replacing the film material, it is necessary to rely on manpower to cut the film material and the appropriate length of tape, and then manually align the front end of the new film material with the tail end of the old film material, and then use the tape to join.

However, in the prior art, since it is necessary to keep an eye on the usage of the film material to prevent the production line from being shut down, labor costs are increased. Secondly, due to the slow speed of manual replacement of the membrane material, the production line must be stopped to replace the membrane material for a long time, which will cause great business losses. Furthermore, since it relies on manual alignment and lamination of the old and new film materials, each time the new and old film materials are joined together, there may be deviations, and it is difficult to quickly and stably attach the two rolls of film materials, and the manual lamination process is even more difficult. There may be a problem of fouling the membrane material.
