Description

Assembly for spraying PCB Technical Field The invention relates to the field of PCB processing, in particular to a component for PCB spraying. Background The PCB can also be called a printed circuit board, can be divided into a single-layer board, a double-layer board, a four-layer board and other multi-layer circuit boards according to the number of layers of the circuit boards, can be correspondingly selected according to actual needs, and needs to be sprayed when being processed. The clamp is used for fixing during spraying, so that the clamp is particularly important to use, however, at present, part of the clamp is only suitable for a single-size PCB, and the damage to the PCB is easily caused when the PCB clamp is fastened, so that the use effect of the clamp is reduced. Therefore, the PCB spraying clamp with the patent number of CN220697165U has the defects that when the PCB is fixed, spraying work can be carried out on different end faces of the PCB only by moving the spraying equipment to the front side and the rear side of the PCB, and the processing work of products is not facilitated. Disclosure of Invention The invention aims to provide an assembly for spraying a PCB. The technical problems of the invention are mainly solved by the following technical scheme: The assembly for spraying the PCB comprises a tray body, wherein a 匚 type frame is arranged in the tray body, a strip-shaped plate I, a limiting mechanism and a strip-shaped plate II are sequentially arranged above the 匚 type frame, a rotating shaft penetrating through the 匚 type frame is arranged on the strip-shaped plate I, the strip-shaped plate II is driven by a lifting mechanism, and the rotating shaft and the lifting mechanism are driven by a rotating mechanism; The lifting mechanism comprises a hydraulic rod, a base is arranged at the bottom end of the hydraulic rod, a square rod connected with a strip-shaped plate II is fixed on the base through a bearing I, a square tube is sleeved on the square rod, and the square tube is fixed on a mounting plate through a bearing II; The rotating mechanism comprises a vertical rod driven by a motor, belt pulleys are arranged at the upper end and the lower end of the vertical rod, corresponding rotating shafts and square pipes, and the two groups of belt pulleys corresponding to the same horizontal plane are connected through a transmission belt. Preferably, a rack is arranged on the tray body, a support plate I for fixing a motor and a support plate II for fixing a hydraulic rod are arranged on the rack, and the mounting plate is fixedly connected with the rack.
