Method for driving link mechanism in variable motion range to grasp industrial wastes by servo motor

Abstract

The invention relates to a method for driving a link mechanism in variable motion range to grasp industrial wastes by a servo motor. The device is characterized by comprising a base 1, a big arm lifting mechanism, a wrist connecting rod pitching mechanism, a servo driving device, a first locking device 9 and a second locking device 19, wherein the big arm lifting mechanism is composed of a big arm 14 and a lifting mechanism; the big arm 14 is connected with the base 1 through a seventh rotating pair 13; the servo driving device comprises a first servo motor which is connected with a driving rod 3 and is used for driving the driving rod 3 to rotate; the first locking device 9 and the second locking device 19 are locked in electromagnetic manner. According to the method, a traditional hydraulic driving mechanism is replaced by a novel connecting rod driving mechanism; the defects of complex hydraulic system, easiness in oil leakage, high processing precision requirement, and the like, of a hydraulic industrial waste grasping machine can be overcome; the locking device is arranged on the rotating pair and one driving rod is utilized to realize the grasping operation for the industrial wastes at two degrees of freedom, so that the use quantity of the motor can be reduced.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a method for grasping and packing industrial waste by using a servo motor to drive a variable-activity link mechanism. Background technique [0002] Due to the shortage of personnel in the labor market, the increase in labor costs year by year and the enhancement of enterprises' awareness of labor protection have promoted the wide application of industrial waste grabbing machines in industrial waste grabbing and loading operations. There are two types of industrial waste grabbing machines: mechanical and hydraulic. At present, most of the mechanical arms of industrial waste grabbing machines are driven by hydraulic pressure. Since hydraulic transmission uses hydraulic oil as the medium for power transmission, there are the following problems: its starting performance is poor, It is easy to leak due to the wear of internal components, and the leaked hydraulic oil will pollute the environm...

Problems solved by technology

There are two types of industrial waste grabbing machines: mechanical and hydraulic. At present, most of the mechanical arms of industrial waste grabbing machines are driven by hydraulic pressure. Since hydraulic transmission uses hydraulic oil as the medium for power transmission, there are the following problems: its starting performance is poor, It is easy to leak due to the wear of internal components, and the leaked hydraulic oil will pollute the environment. The hydraulic oil is greatly affected by temperature, the overall efficiency is low, and sometimes there is noise and vibration

At present, there are very few variable-degree-of-freedom mechanisms that can be applied to practical applications, and no variable-degree-of-freedom mechanisms that have been applied to industrial waste grabbing machines have been seen.
