Elastic cooling and pressing fixture for PCB

Abstract

The invention discloses an elastic cooling and pressing fixture for a PCB. The elastic cooling and pressing fixture for the PCB comprises a support and is characterized by further comprising a cylinder, a movably plate, a plurality of springs, a pressing plate, a cooling pipe and a flexible pipe, wherein 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 cylinder is arranged on the bottom of the top plate, a cylinder rod of the cylinder is connected with the movably plate, the springs are arranged on the bottom of the movable plate, the pressing plate is arranged on the bottoms of the springs, the cooling pipe penetrates through the pressing plate, a water inlet and a water outlet of the cooling pipe are connected through the flexible pipe, the flexible pipe is cooled through a condenser, and an openable hole used for water injection is formed in the cooling pipe. The elastic cooling and pressing fixture for the PCB has the advantages that the structure is simple, the pre-pressing force is balanced, the pressing effect is good, the precision of pressing positions is high, the cooling speed is high, and the machining efficiency and the machining quality can be improved greatly.

Description

technical field [0001] The invention relates to a compression fixture, in particular to a PCB board elastic cooling compression fixture. 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. During the PCB board manufacturing process, the PCB board needs to be pressed tightly so that it does not move and is convenient for processing operations. However, at present, the PCB board pressing jig usually connects a large spring between the cylinder rod and the center of the pressure plate, so that Although the secondary extrusion of the pressing plate can be realized, since a spring is used for elastic extrusion, the entire pressing plate is under force at t...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that a spring is connected between the cylinder rod and the center position of the pressure plate in the PCB board pressing fixture in the prior art, the force on the pressure plate is not balanced enough, and the pressing position of the pressure plate is not accurate enough, and the cooling speed of the PCB board is slow, which affects the processing efficiency. question
