Description

Technical Field

[0001] The present invention relates to the field of circuit board spraying, and in particular to a circuit board spraying device and an operating method. Background Art

[0002] Circuit boards are known by various names, including ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCBs, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, and printed circuit boards. Circuit boards miniaturize and visualize circuits, playing a vital role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards can be called printed circuit boards or printed circuit boards, and their English names include PCBs, FPCs, and rigid-flex boards (reechas). The emergence and development of FPCs and PCBs gave rise to the new product, rigid-flex boards. Therefore, a rigid-flex board is a flexible circuit board and a rigid circuit board, combined through lamination and other processes according to relevant process requirements, resulting in a circuit board that possesses both FPC and PCB characteristics.

[0003] In the prior art, CN114345591B discloses a circuit board spraying device. This patent can meet the requirements of spraying circuit boards, and this patent points out that before turning on the paint pump, the paint is allowed to enter the inner side of the fan-shaped cavity through the paint inlet pipe, and then evenly distributed from the inner side of the fan-shaped cavity to the inner side of the branch pipe, and then sprayed out from the through-hole at the bottom inner side of the connecting plate. At the same time, the outer side of the adhered circuit board is sprayed in conjunction with the convex groove at the bottom inner side of the box body. The convex groove itself is a square hole and is perpendicular to the circuit board moving below. Its main function is to intercept part of the paint mist sprayed from the through-hole, so as to ensure that the paint on the surface of the circuit board is adhered in the form of uniform paint mist, thereby avoiding the problem of unevenness when spraying the circuit board. The inner wall of the box body is provided with a heating and heat-insulating layer, which can recycle the excess paint after interception and then lead it out from the connecting pipe for reuse.

[0004] However, paint adheres to the inner wall of each branch pipe, and after accumulating for a long time, it will inevitably have a certain impact on the subsequent spraying process. In addition, the branch pipe is arranged inside the fan-shaped cavity.
