Embodiment Construction

[0090] Relevant detailed description and technical contents of the present invention are as follows with regard to coordinating illustrations now. Furthermore, for the convenience of illustration, the proportions of the diagrams in the present invention are not necessarily drawn according to the actual scale, but may be exaggerated. These diagrams and their proportions are not intended to limit the scope of the present invention.

[0091] The invention provides a reciprocating linear encoder, which is used to measure the travel distance of the conveyor belt and feed back the acquired value to the computing unit. The reciprocating linear encoder can be applied to an optical detection platform for precise detection of panels and blanks. When the camera device is used to detect the defects of panels and materials, it can ensure that each image frame obtained by the camera device maintains the same accuracy without distortion.

[0092] see figure 1 , is a schematic diagram of th...

Abstract

An optical detection platform includes a conveying device, a camera device, a vacuum leveling device, and a reciprocating linear encoder. The conveying device drives the conveyor belt to move toward a detection direction. The camera takes pictures in the direction of the conveyor belt to define a region to be tested on the conveyor belt. The vacuum leveling device provides suction force for the plurality of through holes on the conveyor belt. The reciprocating linear encoder is used to measure the precise position and travel distance of the conveyor belt.

Description

technical field [0001] The invention provides an optical detection platform, especially an optical detection platform that can accurately measure the position and travel distance of the transmission belt. Background technique [0002] In the field of automation industry, when precise position positioning is required, it is generally necessary to rely on an encoder (Encoder) to accurately measure the mechanism or device. In addition to position detection, the encoder can also accurately measure the rotation angle and rotation speed. , moving speed and acceleration. [0003] Encoders can be mainly divided into two types. One is a rotary encoder that converts the rotational position or amount of rotation into an analog or digital signal. It is generally used on a rotary shaft and then converted into linear distance feedback. , the other is a linear encoder (LinearEncoder) that converts the linear position or linear displacement into an analog or digital signal, and is generall...
