A convenient pressing and positioning mechanism based on pcb numerical control machine tool

Abstract

The invention discloses a convenient pressing and positioning mechanism based on a PCB numerical control machine tool, which includes a workbench, and pressing components are installed on both sides of the workbench, and shaft seats are symmetrically installed on the inner surface of the top of the installation bar. A worm is connected between the two shaft seats through bearing rotation, and a screw is connected to the inner bottom end surface of the installation bar equidistantly through the bearing rotation. The threaded core is connected with a nut, and the nut is embedded and installed in the middle of the compression plate. The invention is scientific and reasonable, and safe and convenient to use. The worm wheel drives the screw to rotate, and then drives the compression plate to compress the PCB under the action of the nut. The two worm gears rotate synchronously, so that the pressing plates can move down synchronously, ensuring that all the pressing plates can press the PCB, and the components of the pressing assembly are driven by the physical structure, the maintenance cost is low, and it is easy to replace and overhaul.

Description

technical field [0001] The invention relates to the technical field of PCB processing, in particular to a convenient pressing and positioning mechanism based on a PCB numerical control machine tool. Background technique [0002] The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. During the PCB processing process, the PCB needs to be fixed to achieve the situation that the PCB board in the processing room will not be displaced. It is published in China. The patent is a pressing and positioning mechanism for PCB CNC machine tools (authorized announcement number CN208826126 U). In this patented technology, the main application method is to install the pressing mechanism on the back end and the left and right ends of the...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a convenient pressing and positioning mechanism based on a PCB numerical control machine tool, which can effectively solve the problem of increasing the maintenance cost of the equipment due to the use of the cylinder in the pressing mechanism during the actual use of the pressing mechanism proposed in the above background technology, and When the gas supply of some cylinders is insufficient, the PCB will not be able to be compressed locally, resulting in a problem that the compression effect is reduced.
