Automatic feeding and positioning device for three-layer combined soft board

Abstract

The invention provides an automatic feeding and positioning device for a three-layer combined flexible board. The automatic feeding and positioning device for the three-layer combined soft board comprises a first ejector plate, a second ejector plate, an ejector plate driving assembly for driving the first ejector plate and the second ejector plate to move up and down, a suction cup assembly, a positioning platform for secondarily positioning materials and a driving sliding rail, wherein the ejector plate driving assembly is arranged on the lower side of the first ejector plate and the lower side of the second ejector plate, one end of the suction cup assembly is slidably connected to the driving sliding rails, the other end of the suction cup assembly extends to the first ejector plate, the positioning platform is fixedly connected between the two driving sliding rails, and a vacuum suction cup in the suction cup assembly is a self-closing suction cup. According to the material feeding device, it is guaranteed that after the multiple vacuum suction cups make contact with materials, enough air can firmly suck the materials, meanwhile, through cooperation of the first ejector plate and the second ejector plate, the tops of the materials can be kept flat under the condition that the feeding amount is large, and therefore the feeding amount is increased.

Description

Technical field [0001] The present invention relates to the technical field of automatic material positioning, and more particularly to a trimming combined soft plate automatic upper positioning device. Background technique [0002] Three-layer thin film switchboard (Keyboard, Notebook printed circuit board, Poly Dome polyester film button) and various buttonned name or touch panels are difficult to achieve after the shape is diverse, thick, easy to bend, and high torque Fully automated upper detection. [0003] The machine of the prior art is a normal vacuum nozzle. When the material is placed in unlatifed or misplaced, the ordinary vacuum nozzle will leak vacuum, resulting in causing the consequences of the entire material. , Timely, it is possible to absorb the material will also fall off during the feeding process, which seriously affects the above-induction of the above-induced device; [0004] Further, in the prior art, the machine is directly transferred to the detection g...

AI Technical Summary

Problems solved by technology

[0002] Three-layer membrane switch boards (KEYBOARD, NOTEBOOK printed circuit boards, poly dome polyester film keys) and various key-type nameplates or touch panels have various shapes, uneven thickness, and are easy to bend. It is difficult to realize after high stacking. Fully automated feeding inspection

[0003] The machine of the feeding device in the prior art uses ordinary vacuum nozzles. When the material is placed unevenly or misplaced, the ordinary vacuum nozzle will leak vacuum, resulting in the consequence that the entire piece of material cannot be sucked up. , the material can be barely sucked up in time, and it will also fall off during the feeding process, which will seriously affect the feeding effect of the feeding device;

[0004] Further, in the prior art, after the material is sucked up, the machine is directly transferred to the detection fixture table. Since the materials are often placed in piles at the discharge position, when the material is directly sucked up and placed on the detection fixture table, it cannot Ensure that the position of each piece of material on the fixture table is consistent, which will result in poor positioning accuracy, resulting in low test accuracy;

[0005] At the same time, the top material table of the machine platform in the prior art is a whole flat plate, which cannot solve the problem that the uppermost side of the material is uneven when the material is piled up too much. Therefore, the order table in the prior art is designed to alleviate this problem. , often only a small amount of material can be accumulated, and it needs to be reloaded in less than 20 minutes, and the automation efficiency is extremely low
