Pick-up mechanism for workpiece loading and unloading

Abstract

The invention provides a pick-up mechanism for workpiece loading and unloading. The mechanism comprises a pick-up unit body, wherein the pick-up unit body comprises a first drive assembly, a sucking disc assembly and a magnetic attraction assembly, and the sucking disc assembly and the magnetic attraction assembly are fixedly connected to a movable block of the first drive assembly; the sucking disc assembly comprises a plurality of sucking discs for adsorbing a to-be-picked-up workpiece; the magnetic attraction assembly comprises magnets for adsorbing the ferromagnetic portion of the to-be-picked-up workpiece ; and driven by the first drive assembly, the sucking disc assembly and the magnetic attraction assembly move towards the to-be-picked-up workpiece so as to correspondingly pick up different parts of the to-be-picked-up workpiece. The pick-up mechanism for workpiece loading and unloading has the advantages of being ingenious in structure and reasonable in design; vacuum negativepressure and magnetic attraction are jointly adopted, so that fast pickup for the to-be-picked-up workpiece is achieved, thus solving the problem of fast pickup for an irregular workpiece; and meanwhile, the pick-up process is efficient and accurate, and pick-up clamping force can be continuously adjusted, thus meeting the requirements of automatic workpiece loading and unloading.

Description

Technical field [0001] The invention belongs to the field of automation, and particularly relates to a picking mechanism for loading and unloading workpieces. Background technique [0002] As the degree of industrial automation continues to increase, the manufacturing industry is gradually becoming intelligent and unmanned; especially for the equipment for loading and unloading workpieces, the degree of mechanization determines the overall production efficiency. At present, the mechanism for picking up workpieces is commonly used in gripper-type clamping mechanisms or sucker-type suction mechanisms. However, as the complexity of the workpiece becomes higher and higher, ordinary picking mechanisms cannot meet the requirements of automation, especially for irregular workpieces. Robotic arm picking is expensive and complicated to control, and it is not efficient for continuous picking of multiple workpieces in a small area. [0003] In this regard, it is urgent to improve the existin...

At present, the mechanism for picking up workpieces is commonly used in clamping jaws or suction cups. However, as the complexity of workpieces becomes higher and higher, ordinary picking mechanisms can no longer meet the requirements of automation, especially for irregular workpieces. The robot arm picks up, the cost is high, the control is complicated, and the efficiency of continuous picking of multiple workpieces in a small area is not high
