Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit boards, in particular to a glue coating head for a printed circuit board. Background Art

[0002] During the production of printed circuit boards, the film needs to be coated with glue, also known as coating, and a glue coating head is required. Printed circuit boards are providers of electrical connections for electronic components. They can make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. With the development of printed circuit board technology, printed circuit boards have occupied an absolute dominant position in the electronics industry. The use of printed circuit board films is also increasing, and the quality requirements for films are also getting higher and higher. The quality of the film directly affects the quality of the printed circuit board.

[0003] After searching, it was found that the publication number is CN116764848A, and the name is a printed circuit board film coating production equipment that is easy to adjust the angle. The application proposes that the printed circuit board film needs a coating equipment to perform a coating process during the production and processing to increase the functionality of the film. Spray coating is a more common type of coating equipment. It belongs to a non-contact coating method. It uses a high-pressure spray coating head to coat the surface of the film. It has a high degree of automation and uniform coating of the film. Since the position of the spray coating head is generally fixed, it is not conducive to adjusting the angle. It is not conducive to adjusting the coverage range according to actual needs during spraying, which affects the work efficiency. The first gear is driven to rotate through the roller through the second rotary drive mechanism. The second gear rotates, thereby driving the rotating shaft and the third gear at the bottom of the rotating shaft to rotate, and the third gear meshes with the fourth gear, thereby driving the fourth gear and the transmission shaft to rotate, and the transmission shaft drives the adjustment part and the spray coating head fixed at the bottom of the adjustment part to adjust the angle, thereby adjusting the coverage range of the paint spray. It can be freely adjusted according to the characteristics of different paints or different coating requirements, thereby increasing the practicality of the main body of the coating equipment. However, this application can only adjust the angle of the spray coating head in a single direction, and the adjustment range is small. The adjustment mechanism is linked with the stirring mechanism and cannot be adjusted alone. It has great limitations on use, and the coating height cannot be adjusted in a targeted manner, which affects the adjustment and work efficiency. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
