Film pasting device and production line

Abstract

The invention relates to the technical field of film pasting equipment, and particularly discloses a film pasting device and a production line. The film pasting device comprises a bracket, a driving part, a pressing head, an attachment head assembly and a pressure detection piece. The driving part is connected to the bracket, the pressing head is connected to the output end of the driving part, and the driving part can drive the pressing head to reciprocate in the vertical direction, the attachment head assembly is used for abutting against a film, the attachment head assembly is movably clamped to the pressing head, can move in the vertical direction relative to the pressing head and can reciprocate in the vertical direction along with the pressing head, and the pressure detection piece is connected to the upper end of the attachment head assembly; when a gap is formed between the attachment head assembly and the film, the attachment head assembly is clamped to the pressing head, and a preset gap is formed between the pressing head and the pressure detection piece; and when the attachment head assembly drives the diaphragm to make contact with a product, the pressing head slides in the vertical direction relative to the attachment head assembly, or the pressing head abuts against the pressure detection piece. According to the film pasting device, the pressure of the attachment head assembly on the film can be accurately controlled, and it is avoided that a product is damaged or the film is not firmly bonded.

Description

technical field [0001] The invention relates to the technical field of film sticking equipment, in particular to a film sticking device and a production line. Background technique [0002] In the prior art, in the production process of products such as glass panels and substrates, it is often necessary to use a film sticking device to stick a film on the surface of the product to protect the product. When sticking the film, it is often necessary to press down the film and keep it for a certain period of time to make the film stick firmly. Therefore, the film sticking device usually includes a driver and an attachment head, and the drive is connected to the attachment head for driving the attachment. The head is pressed against the diaphragm. In order to prevent the product from being damaged due to excessive pressure of the attachment head against the product, and to prevent the film from being weakly bonded due to too little pressure, the film sticking device also includes...

AI Technical Summary

Problems solved by technology

In the prior art, the pressure detection part and the attachment head are often connected flexibly, directly fixedly or through a spring connection, but the direct fixed connection in the prior art itself will cause the pressure detection part to generate a pressure value, giving the pressure detection When the pressure applied by the attachment head increases linearly through the pressure detection part connected by the spring, the pressure value detected by the pressure detection part increases non-linearly, which leads to the discrepancy between the detected pressure value and the actual pressure value, resulting in damage to the product Or the diaphragm is not bonded firmly
