Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to an automatic film pressing device for a circuit board. Background Art

[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum base board, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances.

[0003] After searching, it was found that the publication number is CN215453446U, and the name is an automatic film pressing device for HDI precision circuit boards. The application proposes that when producing circuit boards, it is necessary to apply film on the circuit boards. Since the film applying action is continuously performed by a film applying roller, and there is a large gap between the front and rear circuit boards, when the gap between the two circuit boards moves to the position of the film applying roller, there is no circuit board in the gap, which leads to the problem that the film corresponding to the gap is wasted. By setting a spacing control structure, when the infrared light emitted by the first infrared emitting device passes through the gap between the front and rear circuit boards, the first infrared receiving device can receive the infrared light, and by calculating the first infrared The distance between the front and rear circuit boards can be known by the time when the receiving device receives the infrared light and the linear speed of the first conveying roller group. When the distance between the front and rear circuit boards exceeds the maximum limit, the first infrared receiving device controls the first motor to increase the speed of rotation, resulting in an increase in the movement speed of the rear circuit board, thereby reducing the gap between the front and rear circuit boards, thereby reducing the waste of the film. However, this application requires multiple sets of infrared receiving and transmitting devices, and requires setting thresholds. It is necessary to design a separate control program and system, and a separate control device. It has high requirements on the reaction speed and accuracy of the motor, a complex control structure, and is more troublesome to debug and use. Further improvements can be made.

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