The invention relates to motor protector detection equipment and a control circuit thereof. The detection unit comprises a lifting platform and a first power source; two sides above the lifting platform are provided with a three-phase electrode power strip, a wiring power strip and a second power source; a gear adjusting tool bit, a servo motor for driving the gear adjusting tool bit to rotate, adetection optical fiber sensor and a third power source are arranged over the lifting table. A detection blocking column and a fourth power source are arranged at one end, close to the kicking area, of the lifting table; a blocking photoelectric switch is arranged on one side of the detection blocking column; a feeding blocking column and a fifth power source for driving the feeding blocking column to act are arranged at the end, close to the detection area, of the feeding area, a feeding photoelectric switch is arranged on one side of the feeding blocking column, a removing ejector rod and asixth power source for driving the removing ejector rod to act are arranged on the kicking area, and a removing photoelectric switch is arranged on one side of the removing ejector rod. According to the motor protector detection equipment, automatic detection of the motor protector is realized, and the detection efficiency and the detection accuracy of products are greatly improved.
Description
technical field [0001] The present invention relates to one, in particular to a motor protector detection device and a control circuit thereof. Background technique [0002] The motor protector is a protector that can cut off the circuit circuit in time when the line loses phase or is overloaded, so as to prevent the motor from continuing to run under fault conditions. The motor protector needs to be inspected before leaving the factory after the production and assembly is completed. The inspection steps of the existing motor protector are: 1. Connect the motor protector to the analog calibration circuit; 2. By adjusting the different gears of the motor protector 3. Screen out qualified and unqualified motor protectors. Due to the cumbersome inspection steps, the efficiency of manual inspection is low, and the accuracy of manual inspection is not high, and there may be unqualified motor protectors when they leave the factory. Contents of the invention [0003] In view of...
