Fixture used for PCB air blowing

Abstract

The invention discloses a fixture used for PCB air blowing. The fixture comprises a clamping device and an air blowing device, the clamping device comprises an elastic clamp and a fixing clamp arranged on the side face of the elastic clamp, the elastic clamp comprises a bottom plate and a pressing plate arranged on the bottom plate, and one end of the pressing plate is connected with one end of the bottom plate through a circular-arc-shaped transition section. The other end of the pressing plate is connected with the other end of the bottom plate in an opening and closing mode. A handle is arranged on the pressing plate, the fixing clamp comprises a fixing block, and a through groove is formed in one side, facing toward the elastic clamp, of the fixing block. The through groove is formed in the width direction of the fixing block, and the air blowing device comprises an air blowing nozzle and air compressors connected with the air blowing nozzle. The air blowing nozzle is connected with the air compressors through a pipeline. The fixture used for PCB air blowing comprises the clamping device and the air blowing device, wherein the clamping device is used for fixing a PCB so that the PCB can be convenient to clear through the air blowing device, and the fixture is suitable for blowing air to PCBs of various specifications and has good application prospects.

Description

technical field [0001] The invention belongs to the technical field of PCB auxiliary equipment, and in particular relates to a jig for blowing air on a PCB board. Background technique [0002] During the production process of the PCB board, a lot of waste will accumulate on the surface, and at the same time, dust in the air will also settle and accumulate on its surface. Therefore, before the PCB board is sold out of the factory, its surface needs to be cleaned. There are many parts and wires arranged on the surface of the board, which is a precision instrument. It is impossible to clean up dust and waste by shaking or wiping. Therefore, the method of blowing air is generally used, that is, after fixing the PCB board Blowing air blows away the dust and waste on the surface of the PCB board, but the existing air blowing fixtures have a large limit on the size of the PCB board when fixing the PCB board, which cannot be used universally, resulting in various types of blowing fi...

[0002] During the production process of the PCB board, a lot of waste will accumulate on the surface, and at the same time, dust in the air will also settle and accumulate on its surface. Therefore, before the PCB board is sold out of the factory, its surface needs to be cleaned. There are many parts and wires arranged on the surface of the board, which is a precision instrument. It is impossible to clean up dust and waste by shaking or wiping. Therefore, the method of blowing air is generally used, that is, after fixing the PCB board Blowing air blows away the dust and waste on the surface of the PCB board, but the existing air blowing fixtures have a large limit on the size of the PCB board when fixing the PCB board, which cannot be used universally, resulting in various types of blowing fixtures. Tools are piled up in the warehouse, wasting resources and funds and polluting the environment, which is undoubtedly detrimental to the production of manufacturers
