Abstract

The invention discloses a screen mesh tightening device driven by air cylinders. The device comprises a supporting platform, wherein the positions in the four directions of the top of the supporting platform are each provided with a row of clamping devices; each clamping device comprises a sliding base and a sliding table on the upper part of the sliding base; each sliding table is connected withthe corresponding sliding base in a sliding mode; the sliding direction is towards the opposite side of the supporting platform; a cylinder for driving the corresponding sliding table to slide is arranged behind the corresponding sliding table; a piston rod of each air cylinder is fixed with the corresponding sliding table; a cylinder barrel is fixed with the corresponding sliding base; a pressingrod is hinged to the upper part of the middle of the corresponding sliding table; an upper clamping jaw is fixed at the outer end of each pressing rod; a lower clamping jaw matched with the corresponding upper clamping jaw is fixed at the front part of the corresponding sliding table; a driving rod is hinged to the lower portion of the middle of the corresponding sliding table; and the middle part of each driving rod and the middle part of the corresponding pressing rod are hinged to a connecting rod. According to the screen mesh tightening device driven by the air cylinders, a screen mesh can be tightened, so that subsequent fixation of a frame is facilitated and the problem in the background art is effectively solved.

Description

technical field [0001] The invention relates to a cylinder-driven screen tensioning device. Background technique [0002] The full name of the screen printing machine is "screen printing machine". It is a kind of equipment that prints solder paste or patch glue onto the PCB pad through the screen. It can be divided into vertical screen printing machine, oblique arm screen printing machine, and turntable screen printing Machine, four-column screen printing machine and automatic screen printing machine, mainly used in the electronic processing industry, printed circuit board silk screen logo, instrument shell panel logo, solder paste printing in the process of circuit board processing, etc. Before the wire mesh is used, it needs to be tightened and fixed on the frame before it can be used in the wire mesh machine. At present, there is no special tensioning device for the wire mesh. Contents of the invention [0003] In view of the above problems, the present invention provi...
