[0023] This utility model provides a film-applying mechanism for an FPC dry film pre-applying machine, comprising a frame 1, on which an upper film-applying mechanism 2 and a lower film-applying mechanism 3 are mounted. The upper film-applying mechanism 2 includes an upper seat 20, an upper pressure plate 21, a first Z-axis linear drive mechanism 22, a first film-pulling mechanism 23, and a first film-cutting mechanism 24, all mounted on the frame 1. The first Z-axis linear drive mechanism 22 is mounted on the upper seat 20 and is used to drive the upper pressure plate 21 to move up and down. The upper pressure plate 21 has a first air-collecting chamber 210 inside, and first adsorption holes communicating with the first air-collecting chamber 210 are evenly distributed on the bottom surface of the upper pressure plate 21.

[0024] Its working principle is as follows: When used in conjunction with a dry film feeder, one end of the upper and lower film rolls on the feeder is clamped by the first film-pulling mechanism 23 and the second film-pulling mechanism 33, respectively. The first and second film-pulling mechanisms 23 and 33 respectively pull the upper and lower dry films horizontally to the lower side of the upper pressure plate 21 and the upper side of the lower pressure plate 31.
