[0002] COF, often called chip-on-film, is a soft film assembly technology that fixes an integrated circuit (IC) on a flexible packaging substrate, and uses a flexible packaging substrate as a packaging chip carrier to combine the chip with the flexible substrate circuit. With the continuous development of science and technology, electronic products are developing towards miniaturization, intelligence, high performance and high reliability. In the COF production process, the COF substrate needs to be sprayed, but the existing spraying device has the following problems:

[0003] 1. During spraying, the colloid easily adheres to the inside of the nozzle, causing the nozzle to be blocked. Special equipment is required to clean the residual colloid inside the nozzle, especially after the colloid solidifies, the cleaning difficulty inside the nozzle is greatly increased:

[0004] 2. The colloid in the glue storage barrel is prone to coagulation or precipitation. Usually, a stirring device is set inside the glue storage barrel. The stirring device requires additional driving force for stirring, which wastes resources. Moreover, after the gluing operation is completed, the inner wall of the glue storage barrel still needs to be cleaned:

[0005] 3. The existing COF substrate needs to be left to dry after being coated, which prolongs the production time, affects the subsequent processes, and thus reduces production efficiency. Summary of the invention

At the same time, when the nozzles 35 in different rows are replaced for spraying, when the nozzles 35 used in the previous row of spraying exhaust gas to dry the COF substrate 10, the gas can impact the inside of the nozzle 35 to prevent the colloid from clogging the nozzle 35.

[0052] When the sliding plate 20 moves downward, the extrusion bag 22 is in a stretched state, and external air enters the extrusion bag 22 through the air inlet valve in the fixed plate 19;

[0053] When the colloid in the glue storage box is used up and the elastic bag 26 needs to be cleaned, the control valve in the vent pipe 28 is opened, and the gas in the squeeze bag 22 enters the gas storage chamber 27. The middle part of the elastic bag 26 is squeezed into a concave structure. The stirring member 25 moves in contact with the inner wall of the elastic bag 26 when rotating, and the inside of the elastic bag 26 is scraped and cleaned. At the same time, during the spraying process, when the middle part of the elastic bag 26 is squeezed into a concave structure, the stirring member 25 moves in contact with the inner wall of the elastic bag 26 when rotating, which can also prevent the substances in the colloid from precipitating at the lower end of the elastic bag 26.

[0054] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural modes and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they shall all fall within the scope of protection of the present invention.
