Automatic film pasting device for edge of printed circuit board

Abstract

The invention discloses an automatic film pasting device for the edge of a printed circuit board. The automatic film pasting device comprises two film pasting mechanisms, a plate rotating mechanism and a positioning mechanism are arranged between the film pasting mechanisms, the each film pasting mechanism comprises rolling assemblies arranged on the two sides of the circuit board, the rolling assemblies are provided with protective film roll materials, the rolling assemblies are sequentially provided with flattening roller sets, bending rollers and shaping wheels, a protective film is gradually pasted to the top face and the bottom face of the circuit board through the flattening roller sets, the bending rollers and the shaping wheels, and cutting-off mechanisms are arranged behind the rolling assemblies and are provided with cutters and cutter holders, the cutters are arranged above the protective film on the two sides of the circuit board, the cutter holders are arranged below the protective film, the cutters match with the cutter holders to cut off the protective film, the rotating plate mechanism comprises a rotating plate and a pressing cover and is used for rotating the circuit board, the positioning mechanism comprises side push plates arranged on the two sides of conveying tracks, and the sliding direction of the side push plates is horizontally perpendicular to the conveying direction of the circuit board, the protective film can be automatically pasted on four sides of the circuit board, the efficiency is high, and the pasting width of the protective film on the upper and lower surfaces 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.
