PCB circuit board fixed processing equipment

Abstract

The invention discloses a fixed processing equipment for PCB circuit boards, belonging to the technical field of PCB circuit board processing, comprising a fixed bottom plate, a limiting cylinder is installed in the upper middle of the fixed bottom plate, and a left-handed thread rod and a right-handed thread connected to each other are installed inside the limiting cylinder Rods, left-handed threaded rods and right-handed threaded rods are respectively equipped with moving blocks in the middle, and the upper end of the moving block is connected with a moving rod. A rotating shaft is connected through a bearing, and a lifting mechanism is installed on both sides of the upper end of the fixed base plate. The first guide block and the lower end of the first moving block are equipped with a limiting plate. The invention realizes the change of the distance between the U-shaped fixing plates, ensures the double-sided processing of the PCB circuit board, and realizes the all-round processing of the PCB circuit board.

Description

technical field [0001] The invention relates to the technical field of PCB circuit board processing, in particular to a fixed processing equipment for PCB circuit boards. Background technique [0002] PCB circuit board, also known as printed circuit board, is the provider of electrical connection for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves automation and production labor rates. [0003] There are various specifications of PCB circuit boards on the market, but PCB circuit boards usually have a cleaning process before electroplating. This is because human contact or other inevitable external factors will cause contamination on the surface of the circuit board.

[0003] There are various specifications of PCB circuit boards on the market, but PCB circuit boards usually have a cleaning process before electroplating. This is because human contact or other inevitable external factors will cause contamination on the surface of the circuit board. The surface cleaning is not thorough, and in the presence of pollutants, the electroplating cannot be applied to the partially polluted areas, or the electroplating is easy to fall off due to the influence of temperature during use, and the surface of the electroplated circuit board is generally cleaned manually Time-consuming and inefficient, and manual contact during the cleaning process cannot guarantee the cleanliness of the surface, which has a great impact on the subsequent electroplating quality

[0004] Chinese patent (notification number: CN109121316A) discloses PCB circuit board fixed processing equipment and PCB circuit board fixed processing technology, PCB circuit board fixed processing equipment, including bottom plate, connecting column, fixing mechanism, top plate, limit mechanism and cleaning device, so A fixing mechanism is installed in the middle of the bottom plate, connecting columns are installed symmetrically at the left and right ends of the bottom plate, and a cleaning device is installed on the inner wall of the connecting column at the left end of the bottom plate through a sliding fit. The bearing is installed with a limit mechanism. Although this device ensures the cleanliness of the PCB board surface to a certain extent, in actual operation, it cannot effectively process the PCB board, and cannot realize double-sided processing, and the reliability is not high.
