Magnetic suction disc assembly with automatic adjustment and adaption function

Abstract

The invention discloses a magnetic suction disc assembly with an automatic adjustment and adaption function. The magnetic suction disc assembly is capable of automatically adapting to an adsorption surface of a workpiece, and comprises a suction device, a drive device and a separation device, wherein the separation device comprises a rear separation plate, a rear fixing plate and a front plate-rear plate connection rod; the drive device is directly fixed to the separation device without relative movement with the separation device, and the two devices are directly fixed to a manipulator; the suction device is composed of a plurality of execution units and a fixing plate; and the suction device is driven to take and place the workpiece through the drive device. The magnetic suction disc assembly comprises a plurality of independent suction discs, the suction device carries out self-adaption according to the height of the adsorption surface of the workpiece while encountering an irregular or uneven adsorption surface of the workpiece, and a contact area of the suction discs and the adsorption surface (the irregular surface such as a flat surface, a convex surface and a concave surface) can be increased, so that an adsorption force is increased or reduced, the workpiece with large and many hollows and bulged edges or projecting points can be adsorbed, adsorption with a larger area is guaranteed, and a self-adaption function is realized.

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.
