Abstract

The invention discloses a photoelectric encoder defect detection system and an implementation method thereof and aims to solve the problems in the prior art that the detection efficiency of a photoelectric encoder is low, the false drop rate is high, the cost is high and the technical demand cannot be met. The photoelectric encoder defect detection system comprises a data processing center, and a detection device and a motor which are connected with the data processing center, wherein the detection device comprises an L-shaped mounting seat consisting of a transverse mounting seat and a longitudinal mounting seat connected with the transverse mounting seat; an X-axis moving platform which can move along the horizontal direction and is connected with the motor is arranged on the longitudinal mounting seat; a camera and a lens positioned below the camera are arranged on the X-axis moving platform; a Y-axis moving platform which can move along the vertical direction and is connected with the motor is arranged on the transverse mounting seat; an objective table is arranged on the Y-axis moving platform. According to the scheme, the aims of high performance cost ratio, high efficiency and accuracy are fulfilled, and the photoelectric encoder defect detection system has extremely high practicability and popularization values.

Description

technical field [0001] The invention relates to a defect detection system, in particular to a photoelectric code disk defect detection system and its realization method. Background technique [0002] The photoelectric code disc is made of optical glass, engraved with many concentric code tracks, and each code track has light-transmitting and opaque parts arranged according to certain rules. Since the photoelectric code disc is an important part of many sensors and automatic control systems, it can be used to measure displacement, speed, acceleration, etc., and it has the characteristics of high precision, small size, light weight and fast response. , servo transmission technology, automatic control technology, etc. are widely used. However, the existence of defective products will greatly affect its use effect, so the detection of defective products is particularly important. Traditional manual detection has low efficiency and false detection. However, due to the disadvant...
