Power take-off system for driving cam drive

Abstract

The invention relates to a power output system for driving a cam to drive, and belongs to the field of automated assembly equipment. The power output system comprises a spindle drive mechanism, a tray positioning mechanism, a lift detecting mechanism and a manipulator mechanism, wherein the spindle drive mechanism comprises a spindle motor, a main drive shaft and a bearing seat; a plurality of main gears in the same size are arranged on a main drive shaft; a first cam drive assembly, a second cam drive assembly and a third cam drive assembly are separately engaged with one of the main gears; and the first cam drive assembly, the second cam drive assembly and the third cam drive assembly are driven to move synchronously by the main gears. According to the power output system disclosed by the invention, the cam drive structure has the advantages of high precision, precise synchronous action, simple and stable structure, no vibration and high drive stability; and the power output system does not need to use any electronic control elements and is not connected with any complicated line, so that the power output system is low in manufacturing cost and is particularly suitable for automatic drive with high precision requirements.

Description

technical field [0001] The invention relates to the field of automatic assembly equipment, in particular to a power transmission system, in particular to a power output system for driving cam transmission. Background technique [0002] In automated processing or assembly equipment, in order to meet the needs of mass production, most intelligent assembly platforms can realize assembly line operations, and in intelligent assembly platforms for assembly line operations, power transmission systems are essential, and power transmission systems are used for Provide all the transmission force to the intelligent assembly platform, so as to drive all the motion transmission required by the whole set of processing or assembly equipment, such as manipulator, detection mechanism, lifting mechanism, transmission mechanism, etc. [0003] The power transmission system in the prior art also has the following defects: 1) the circuit of the electronic components and the mechanical structure c...

AI Technical Summary

Problems solved by technology

[0003] The power transmission system in the prior art also has the following defects: 1) the circuit of the electronic components and the mechanical structure controlled by the electronic components are relatively complicated, resulting in a large space occupied by the mechanical structure; 2) the failure of the mechanical components controlled by the electronic components 3) It is necessary to control multiple motors or other driving equipment through one controller to achieve synchronization. Due to the existence of multiple driving equipment, the accuracy requirements for the transmission mechanism Very high, otherwise, the error will be large, which will cause the whole device to fail to work
