PCB cooling and sucking fixture

Abstract

The invention discloses a PCB cooling and sucking fixture. The PCB cooling and sucking fixture comprises a support and is characterized by further comprising an air cylinder, a moving plate, a plurality of blowers, sucking nozzles and a vacuum generator. The support comprises a base, a supporting beam and a top plate, the supporting beam is arranged on the top of the base, the top plate is arranged on the top of the supporting beam, the air cylinder is arranged at the bottom of the top plate, an air cylinder rod of the air cylinder is connected with the moving plate, the moving plate is provided with communicated blowing holes, the blowers are arranged on the top of the moving plate, the bottom of the moving plate is connected with the four sucking nozzles, the sucking nozzles are connected with the vacuum generator through pipelines, and the thickness of the moving plate is 3cm. According to the PCB cooling and sucking fixture, the problems that when the back of a PCB is tested and machined, a good device used for hanging the back of the PCB to bring convenience to testing and machining does not exists, and machining efficiency is affected because the cooling speed of the PCB is low are solved; the PCB cooling and sucking fixture is simple in structure, high in cooling speed, and capable of sucking different faces of the PCB and greatly improving the machining efficiency.

Description

technical field [0001] The invention relates to a jig, in particular to a jig for cooling and absorbing a PCB board. Background technique [0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board and printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. At present, when testing and processing the back of the PCB, there is no good equipment to suspend the back of the PCB to facilitate the testing and processing. It is necessary to manufacture another jig for placement, which is expensive to manufacture and use, and it is troublesome to manage these jigs. At the same time, the current PCB board needs to be cooled during the processing of the PCB board. At present, natural cooling is mostly used, and the cooling speed is slow, which dela...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem in the prior art that there is no better equipment to suspend the back of the PCB board to facilitate the test processing, and at the same time the cooling speed of the PCB board is slow, which affects the processing efficiency, the present invention provides a The structure is simple, the cooling speed is fast, the cost is saved, and the PCB board cooling adsorption fixture can absorb different sides of the PCB board and greatly improve the processing efficiency.
