Background technique

With the development of economy and science and technology, the use of automation equipment in industrial production is becoming more and more extensive, and the problems of low labor efficiency and high cost can be overcome through automation equipment. Especially when grasping and shifting heavy objects, automation equipment can solve the problem of low labor efficiency to a large extent. In the prior art, there are many automated grabbing devices, and grabbing devices with different structures are designed for different types of products. This method is not ideal for processing relatively heavy, unfixed products.

For metal products, the grasping method can be grasped by claws or magnet adsorption. The mechanical claw clamping method has high requirements on the appearance of the workpiece (must be round or fixed square); general plate metal products structure, grabbing by electromagnet adsorption is a high-efficiency method, but when grabbing by electromagnet adsorption, there is still some residual suction on metal products that has not been released, resulting in the inability to easily break away from the electromagnet adsorption. Through the secondary clamping of the jaws, the production cost is increased.

Secondly, when the existing electromagnetic grasping device acts on a plane, it can provide a large magnetic attraction force; however, if the object is a non-planar structure, such as a spherical object, the contact area between the electromagnet and the object is very small, which can provide The magnetic attraction force is small, so the weight of the object that can be grasped is low, and the object is prone to secondary falling.
