Magnetic suction disc assembly with automatic adjustment and adaption function

Abstract

The invention discloses a magnetic sucker assembly with automatic adjustment and adaptation functions, which can automatically adapt to the adsorption surface of workpieces, and includes a suction device, a driving device and a part removal device; the part removal device includes a rear part removal plate, a rear fixing plate and The front and rear plate connecting rods; the driving device is directly fixed on the unloading device, there is no relative movement between the two devices, and the two devices are directly fixed on the manipulator; the suction device is composed of multiple execution units and fixed plates; driven by the driving device The suction device picks up and unloads workpieces. The magnetic chuck assembly includes multiple independent suction cups. When encountering an irregular or uneven workpiece adsorption surface, the suction device will adapt itself according to the height of the workpiece adsorption surface, and can increase or decrease the suction cup and the adsorption surface (flat, convex surface) , Concave and other irregular surfaces) contact area, thereby increasing or reducing the adsorption force, and can adsorb workpieces with large and many hollows, raised edges or protruding points, ensuring a larger area of ​​adsorption and realizing the self-adaptive function.

Description

technical field [0001] The invention belongs to the field of industrial automation, and in particular relates to a magnetic chuck assembly with automatic adjustment and adaptation functions. Background technique [0002] Irregular metal workpieces are used in the production of automobile industry, machine tool industry and other industrial products. In the automated production process, the grasping and unloading of metal workpieces are done autonomously by machines. Metal workpieces can be divided into magnetic metal materials and non-magnetic metal materials. For non-magnetic metal materials, pneumatic or electric grippers can be used to carry metal workpieces, and for magnetic technical materials, magnetic chucks can be used to carry workpieces. In actual production, according to different handling requirements, workpieces are usually lifted, lowered and turned over. Although this kind of complex action can be easily realized by the motor, pneumatic and control system, ...

AI Technical Summary

Problems solved by technology

When the adsorbable surface of the workpiece is uneven, has protruding edges or protruding points, or has large holes, the adsorbable area of ​​the magnetic chuck will decrease, and the reduction in the adsorption area will lead to a decrease in the adsorption force, which will eventually lead to a reduction in the adsorption force of the workpiece. In severe cases, the workpiece will fall off

[0006] Therefore, there is an urgent need for a new magnetic chuck, which can solve the problem of taking and absorbing workpieces with large and many hollows, or with raised edges or protruding points.
