SMT printing process burst buckle jig

Abstract

The invention discloses an SMT printing process burst buckle jig which comprises a jig body arranged on a rack. A groove used for containing a PCB is formed in the jig body, positioning holes are formed in the four corners of the PCB, and the positions, at the two ends of the groove, of the jig body are each provided with a set of positioning mechanisms used for tensioning the positioning holes in the PCB. And each set of positioning mechanisms comprises two symmetrically distributed burst buckle mechanisms. Compared with the prior art, by using the jig of the invention, two burst buckle mechanisms of each set of positioning mechanisms can be independently exploded, the positioning holes in the PCB can be independently expanded, the jig can be suitable for the PCB with the thickness of 0.3 mm-1.2 mm, the utilization rate is greatly increased, and the application range is expanded.

Description

Technical field[0001]The present invention relates to the technical field of circuit board printing fixtures, in particular a SMT printing process buckle.Background technique[0002]SMT printing in the prior art is divided into two, no load printing and printing;[0003]1. No load printing is generally only suitable for a thickness of PCB plates, which cannot be directly printed for a PCB plate having a thin thickness;[0004]2. The carrier printing is widely used, but for thinner PCB board factors, the pressure plate must be used, or the PCB is fixed using the rubber band, otherwise the PCB will be made up, and it will eventually cause printing, waste, cost; The tape and back tape before printing require staff to complete, not only cause cost waste, low work efficiency, easy error, etc., but also unable to achieve fully automated operation mode.[0005]Therefore, it is necessary to improve the SMT printing fixture in the prior art.Inventive content[0006]It is an object of the present inven...

AI Technical Summary

Problems solved by technology

[0003] 1. Carrier-free printing is generally only suitable for thicker PCB boards, and it cannot be printed directly for thinner PCB boards;

[0004] 2. Carrier printing is widely used, but for thinner PCB boards, it is necessary to use a pressure plate, or use adhesive tape to fix the PCB, otherwise it will cause the PCB to warp, and eventually cause poor printing and waste costs; and The sticking tape before printing and the tearing tape at the back end need to be completed by the staff, which will not only cause cost waste, low work efficiency, error-prone and other problems, but also cannot realize the fully automatic operation mode
