Abstract

The invention relates to an electric actuator with a photoelectric positioning mechanism. The electric actuator with the photoelectric positioning mechanism is mainly and technically characterized by comprising a control circuit board, a positioning mechanism, an output shaft, a transmission mechanism and a motor, wherein the motor is connected with the transmission mechanism and drives the output shaft to rotate through the transmission mechanism; the positioning mechanism comprises a photoelectric switch and a positioning plate; the positioning plate is fixedly installed on the output shaft and rotates along with the output shaft; a positioning plate nick is formed on the periphery of the positioning plate; the photoelectric switch is installed on the control circuit board and is positioned in a position where the positioning plate nick rotates to pass by; and when the positioning plate rotates, the photoelectric switch is cut to generate a positioning signal and the positioning signal is output onto the control circuit board. The electric actuator with the photoelectric positioning mechanism is reasonable in design, solves the defect that in the traditional positioning ways such as reed positioning, microswitch positioning and the like, the mechanical life is limited, improves the reliability of a product, meets the need that a variety of control ways are realized on a circuit board and reduces the production cost and the management cost.

Description

technical field [0001] The invention belongs to the field of electric actuators, in particular to an electric actuator with a photoelectric positioning mechanism. Background technique [0002] An electric actuator is a drive device that provides linear or rotary motion, and its positioning methods mainly include reed positioning, micro switch positioning, etc. The structure of the electric actuator mainly includes a cam, a positioning mechanism group, and a control circuit board. The cam is vertically installed on the control circuit board. Touch the reeds or contacts of the positioning mechanism group, thereby generating a control signal. [0003] The above-mentioned reed positioning and micro switch positioning have their own characteristics, but there are also different problems: although the structure of the reed positioning method is simple, the installation and debugging process is complicated, and the mechanical life is limited; the micro switch positioning method is...
