The fully automatic recognition method saves a lot of time and manpower. The whole device is reasonably designed and easy to use, which brings convenience to people.
[0003] The above patent uses a pressing block to press and fix the stamping parts. Automobile stamping parts are similar to the front cover, door, and trunk lid of the car body. These irregular objects are easily damaged by the vertical pressing of the pressing block. Now the automobile manufacturing industry generally uses customized die bases to place automobile stamping parts. The customized die base has an inner lining that fully matches the stamping parts, which can effectively prevent the stamping parts from sliding on its surface. However, the stamping parts placed in the die base need to be assembled and welded vertically. The vertical welding process requires a clamping mechanism to squeeze and clamp the surface of the stamping parts in multiple directions. The clamping mechanism is used for a long time, and burrs are inevitable on the surface. Once it is clamped and in contact with the stamping parts for a long time, it may cause damage to the surface of the stamping parts. The position of the traditional clamping structure is relatively fixed, and the same clamping layout is used when clamping different stamping parts. However, different stamping parts have different force bearing capacities, and the clamping mechanism with the same layout cannot perfectly match different stamping parts. Utility Model Content
