A swing film unwinding device

Abstract

The invention discloses a swing film removing device. The swing film removing device comprises a machine body; the machine body is provided with a conveying system for conveying circuit boards; one end of the machine body is fixedly provided with a swing motor; the swing motor is connected with a spraying device corresponding to the conveying system through a mechanical transmission swing device; and the lower end of the spraying device is provided with a solution circulating device. According to the swing film removing device of the invention, swing spray tubes are adopted to perform spray so as to remove films, and therefore, films on the circuit boards can be quickly removed, and residual films will not stop or shield solution for film releasing spray behind, and film removing efficiency and film removing speed are higher; and spray can be carried out by a certain angle through nozzles, and solution left on the circuit boards can be driven away, and therefore, the influence of the pool effect can be reduced; the swing spray tubes are adopted to perform spray, and spray can be carried out by a certain angle through the nozzles, and therefore, solution can be sprayed at the corners of lines on the boards, and film residues will not be left at the corners.

Description

technical field [0001] The invention relates to the technical field of film removal of printed circuit boards, in particular to a swing film removal device. Background technique [0002] With the development of industry, printed circuit boards are developing in the direction of multi-layer, densification and flexibility, and the lines are getting thinner. When the board is transported through the film-removing process, the traditional film-removing method is sprayed with straight tubes. There are the following technical defects: 1. Straight pipe fixed spraying, the spraying angle is perpendicular to the film, the film retreating speed is slow, and the problem of residual film is prone to appear at the angle of some lines; 2. Straight pipe fixed spraying, the above mentioned The retreated film slag still remains on the board, and the blocking spraying liquid affects the film removal efficiency; 3. Straight pipe fixed spraying, the pool effect on the board affects the uniformi...
