The invention provides a circuit board rolling and film pasting device, which comprises a film supply mechanism, two hot pressing rollers and a rack, wherein the two hot pressing rollers are an upperpressing roller and a lower pressing roller which are vertically arranged side by side, support seats are installed on the rack, and the circuit board rolling and film pasting device further comprisesan air cylinder, a pressure sensor, a controller for controlling the air cylinder to drive air pressure and vibration sources for driving the upper pressing roller to vibrate at high frequency. According to the invention, the support seats are slidably mounted on the two sides of the rack, the upper pressing roller is slidably supported on the rack through the support seats, and the air cylinderis arranged on the rack so as to adjust the film pasting pressure; the pressure sensor is arranged on the support seat so as to monitor the film pasting pressure in real time, so that the film pastingpressure is controlled; and the vibration sources are arranged on the support seats, so that the upper pressing roller vibrates at high frequency during film pasting, the fluidity of a dry film blocking agent is greatly improved, the pit filling capacity and speed are improved, and the adhesive force of a dry film and copper foil is improved so as to ensure the film pasting quality and the film pasting speed.
Description
technical field [0001] The invention belongs to the technical field of circuit board production, and more specifically relates to a circuit board rolling film laminating device. Background technique [0002] In the film pasting industry, the dry film with a resist is generally hot-pressed and pasted on the circuit board; especially in the process of pasting the dry film on the precision circuit board (PCB) and flexible circuit board (FPC), the quality of the dry film It is mainly limited by the uniformity of temperature and pressure and the coordination of speed. The adhesion between dry film and copper foil directly determines the quality of the film. The adhesive force between the dry film and the copper foil on the circuit board is directly proportional to the pressure of the film laminating roller and inversely proportional to the film lamination speed. When pasting the film, the air cylinder is generally used to adjust the distance between the upper and lower heat rol...
