Technical Field
[0001] The utility model relates to the field of grinding equipment, and particularly relates to an automatic feeding unit. Background Art
[0002] During the processing of watch cases, it is necessary to grind the bottom line, ear nozzles, and thin body parts respectively. In the past, three grinding devices were used for processing respectively. After each processing is completed, the material needs to be transported to the next grinding device, and then the workpiece is placed in the grinding device for positioning and grinding. The overall process requires a large amount of labor, and the workpiece needs to be positioned and clamped multiple times, resulting in low efficiency. In view of this defect, a grinding production line is currently developed to automatically complete the grinding processing of each part. However, since the grinding processing time of each process is different, there is a time difference in feeding. When the grinding process with a longer grinding time has not completed the workpiece grinding, a waiting time needs to be set, resulting in that the working efficiency still cannot be greatly improved. Therefore, further improvement is needed. Content of the Utility Model
