Double positioning mechanism for PCB numerical-control machine tool

Abstract

The invention discloses a double positioning mechanism for a PCB numerical-control machine tool. The double positioning mechanism is structurally characterized in that assistant supporting members parallel to each other are fixed on left and right sides of a workbench bottom plate, two ends of a clamping mechanism are arranged in grooves in the middles of the assistant supporting members, two workbench faceplates are fixed on two sides of the clamping mechanism and positioned above the assistant supporting member, and each workbench faceplate is at least provided with a sliding groove for cooperating with a compressing ring to move back and forth; a fastening unit is arranged in a space formed by the workbench faceplates and the workbench bottom plate and is structurally characterized in that an oriented guide rail is arranged right below a sliding groove, the oriented guide rail, an oriented slider, a compression cylinder and a compression ring are arranged sequentially, and the oriented slider is connected to a distance adjusting cylinder. The double positioning mechanism can process PCBs with various size specifications without using a paper adhesive tape to bond and compress each PCB and is flexible and multipurpose, so that time consumed by working personnel at this stage is reduced, and assistant materials are saved.

Description

Technical field [0001] The invention relates to the technical field of PCB (Printed Circuit Board, printed circuit board in Chinese) processing equipment, in particular to a dual positioning mechanism for PCB numerical control machine tools. Background technique [0002] At present, the method of fixing PCB on the market is to pin the PCB, and then fix the pin holes on the bakelite board of the workbench, and then use paper tape to glue the PCB around (one-time use) to prevent the PCB from shifting or The occurrence of edge warping or rotation causes quality problems after product processing. This series are all manual operations. The upper and lower plates and paper tape bonding and pin holes will take a lot of personnel time, time-consuming and inefficient, and will also waste a lot of auxiliary adhesive tape. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a dual positioning mechanism for PCB numerical control machine...

Problems solved by technology

[0002] At present, the way to fix the PCB on the market is to put a pin on the PCB, and then fix the pin hole on the bakelite board of the workbench, and then use paper tape around the PCB (one-time use) to press it tightly to prevent the PCB from shifting or The occurrence of edge warping or rotation, etc., will cause quality problems after product processing

This series is all manual operation. It will take a lot of time for the upper and lower plates and paper tape bonding and fixed pin holes, which is time-consuming and inefficient. At the same time, it will waste a lot of auxiliary adhesive tape
