Pulling device and its pulling method

Abstract

The invention provides a material pulling device and a material pulling method thereof. The material pulling device is used for straightening an upper elastic material strip and a lower elastic material strip. The material pulling device comprises a material mixing device, a driven feeding device and a drivingfeeding device; the driven feeding device comprises a slave moving plate material channel, two driven pulling ratchet wheels, first couplers and driven material shifting wheels, wherein the driven pulling ratchet wheels are used for hooking the upper elastic material strip and the lower elastic material strip respectively, the first couplers sleeve the driven material pulling ratchet wheels, and driven material shifting wheels are fixed on the first couplers; and the driving feeding device comprises a driving elastic sheet material channel, two driving pulling ratchet wheels, first couplers and driving material shifting wheels, wherein the driving pulling ratchet wheels are used for hooking the upper elastic material strip and the lower elastic material strip respectively, the first couplers sleeve the driving material pulling ratchet wheels, and the driving material shiftingwheels and motors are fixed on the first couplers The material pulling device is simple and convenient to operate; and one person can control multiple machines simultaneously, so that the labor cost is saved to the maximum extent, the welding efficiency is improved, and the welding quality and the enterprise competitive capacity are improved.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to a material pulling device and a material pulling method thereof. Background technique [0002] In the field of IT products, especially in the period of rapid development of smart phones, the cost of employment is getting higher and higher. In order to reduce labor costs and realize high-tech automation in this field, automated assembly lines are widely used. The initial material pulling method in the IT industry is usually that the servo motor drives the cylinder equipped with the positioning mechanism of the material belt pulling hole to move. After reaching the set position, the cylinder moves, drives the positioning mechanism to insert into the material belt positioning hole and holds it, and the servo motor moves back Pull the material belt to the set distance, the cylinder resets, the positioning mechanism releases the material belt, and then proceeds to th...
