Description

TECHNICAL FIELD

[0002] In modern industrial production, flexible film laminating machine is widely used in electronic, optical, packaging and other fields. The traditional flexible film laminating machine usually takes off the film on the adhesive glue, then takes off the film on the conductive glue, and according to the interval required by the customer, the conductive glue is pressed on the adhesive glue. Although this design can meet the basic laminating requirements, there are many problems in actual application. First, the adhesive glue film after taking off the film and the conductive glue film after taking off the film cannot be reasonably stored, and can only be stacked around the laminating machine. The waste film stacking will occupy a large amount of production space, affect the neatness of the work area, not only reduce the work efficiency, but also increase the work burden of the operator, and the waste film stacking may hinder the passage, increase the risk of tripping or falling of the personnel, especially in the environment of high-speed production, this risk is more prominent. Because of the waste film stacking, the operator needs to stop regularly for cleaning, which will lead to frequent termination of the production line and reduce the overall production efficiency. More importantly, the interval of the conductive glue on the traditional single laminating machine is fixed. The flexible glue needs different gaps between the conductive glue in different uses. The fixed interval cannot adapt to the production requirements of different gaps, which leads to the need to change the entire equipment or make complex mechanical adjustments when changing the interval between the conductive glue in the production process, increasing the operation difficulty and production cost.
