A printed circuit board edge automatic film sticking device

Abstract

An automatic film-attaching device for the edge of a printed circuit board comprises two sets of film-attaching mechanisms, and a rotating plate mechanism and a positioning mechanism are arranged between the film-attaching mechanisms. The film sticking mechanism includes rolling components arranged on both sides of the circuit board. The rolling component is provided with a protective film roll material. The rolling component is equipped with a flattening roller group, a bending roller and a shaping wheel in turn. The protective film is passed through the flattening roller group, Bending rollers and shaping wheels are gradually pasted to the top and bottom of the circuit board. There is a cutting mechanism behind the rolling assembly, with a cutter and a cutter seat. The cutter is arranged above the protective film on both sides of the circuit board, and the cutter seat is arranged below the protective film. The cutter and the cutter seat cooperate to The protective film is cut off. The rotating plate mechanism includes a rotating plate and a pressing cover for rotating the circuit board. The positioning mechanism includes side push plates arranged on both sides of the conveying track, and the sliding direction of the side push plates is horizontal and perpendicular to the conveying direction of the circuit board. The protective film can be automatically attached to the four sides of the circuit board with high efficiency, and the pasting width of the protective film on the upper and lower sides of the circuit board can be controlled.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board production, in particular to an automatic film sticking device for the edge of a printed circuit board. Background technique [0002] In the production process of the printed circuit board, in order to protect the four sides of the printed circuit board and prevent damage and scratches, etc., a protective film is usually pasted around the circuit board so that the protective film covers the sides and top surface of the circuit board. The part of the bottom near the edge. In the prior art, the circuit board is usually fixed on the rotating device, the circuit board is rotated, and then the protective film is manually wrapped around the circuit board. The degree of automation is low, the work efficiency is not high, and the protective film on the upper and lower sides of the circuit board cannot be guaranteed. The width is uniform. If the protective film is too wide, it is easy to cov...

Problems solved by technology

In the prior art, the circuit board is usually fixed on the rotating device, the circuit board is rotated, and then the protective film is manually wrapped around the circuit board. The degree of automation is low, the work efficiency is not high, and the protective film on the upper and lower sides of the circuit board cannot be guaranteed. The width is uniform and uniform. If the protective film is too wide, it is easy to cover the wiring pattern on the circuit board. If the protective film is too narrow, the protective effect will be reduced.
