Description

Technical Field

[0001] The utility model relates to a coiled material optical detection mechanism, belonging to the technical field of optical detection. Background Technique

[0002] In the existing production process, due to the increasing requirements for product quality in the current market, it is necessary to detect products during the manufacturing process to determine unqualified products and eliminate them, so as to ensure the product quality. The optical detection mechanism automatically scans the PCB through a camera, collects images, compares the tested solder joints with the qualified parameters in the database, and after image processing, checks for defects on the PCB and displays / marks the defects through a display or an automatic marker for maintenance personnel to repair.

[0003] After retrieval, the patent with the publication number CN112553859A discloses a "multi-functional coiled material inspection machine", which includes: a machine table, a first guide wheel is provided at the left end of the machine table base surface, a first pinch roller and a second pinch roller are provided on the right side of the first guide wheel, a first ion hair dryer and a second ion hair dryer are symmetrically arranged in the middle between the first pinch roller and the second pinch roller, and the air outlet is at an appropriate distance from the fabric.

This device greatly improves the quality of the fabric by using both artificial inspection and intelligent detection, and simultaneously measuring the length of the fabric production with a length measuring instrument.

[0004] In the prior art, generally products are set on a material belt, and the rotation of the feeding roller and the unwinding roller is used to realize the movement of the material belt on the loading platform. The position of the product is sensed by a sensor, and then it is moved to the detection area to be detected by a vision detection device. However, since the positions of the feeding roller and the unwinding roller are fixedly set, and the distance between the feeding roller and the unwinding roller is relatively long, even a slight misalignment between the two sides of the material belt will cause a large deviation of the material belt during the transmission process, resulting in a situation where the sensor recognizes the product at the front side but there is still a misalignment between the product and the detection area during detection. The position accuracy of this material belt is poor, and when replacing material belts of different sizes, the movement path of the material belt on the loading platform will change, and the position of the corresponding product will also change. Since the sensor is generally fixedly set, the sensor cannot sense the corresponding product, and the applicability is poor. Summary of the Utility Model
