Problems solved by technology

[0003] However, the lower release protective film needs to be torn off when the copper foil is laminated. The existing method of tearing the film is manual tearing. The artificial tearing film can only correspond to the incoming material as a sheet, and the efficiency is very low. The defective rate of wrinkles after tearing off very high

Abstract

The invention discloses an ultra-thin and easy-to-wrinkle automatic CU foil stripping technology. The technology comprises the following steps that S1, a Cu foil coil is manually placed on a discharging shaft of a discharging assembly; S2, the coil is wound and a lower protective film is wound around a material winding shaft according to the mode shown in figure 2, and the whole material belt is made in a tensioned state; and S3, the copper foil is sucked by a vacuum suction plate 12, a film stripping platform of a film stripping platform assembly moves backwards to realize separation of the copper foil and the lower protective film, so that automatic stripping of the Cu foil can be realized. By applying the scheme, the film stripping rhythm can reach 3.5s per one piece, stable film stripping is realized, the film stripping success rate is greater than or equal to 99.9%, so that the labor cost is saved, the efficiency is high, the stability is good, the foreign matter defect caused by manual contact is reduced, and the wrinkling problem caused by manual film stripping is avoided. The technology overcomes the technical difficulty of module FPC copper foil attaching, and provides a certain technical foundation for later film stripping of various ultra-thin materials.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an automatic peeling technology of ultra-thin and easy-to-wrinkle CU copper foil. Background technique [0002] The incoming material of CU copper foil is roll material, and there is a layer of release protective film underneath. The thickness of the copper foil is extremely thin (about 0.2mm), and it is easy to wrinkle. This kind of material is mostly used in the mobile phone industry, where the copper foil is pasted on the FPC of the module to play the role of isolation and protection. [0003] However, the lower release protective film needs to be torn off when the copper foil is laminated. The existing method of tearing the film is manual tearing. The artificial tearing film can only correspond to the incoming material as a sheet, and the efficiency is very low. The defective rate of wrinkles after tearing off very high. Contents of the invention [0004] The purpose ...
