Description

Technical Field

[0001] The utility model relates to the technical field of optical element detection, and more specifically, to a tray loading device for lens appearance detection. Background Art

[0002] The content of this part only provides background information related to the utility model, which may not constitute prior art.

[0003] With the gradual expansion of the domestic lens industry scale, the market demand and quality requirements for optical lenses are getting higher and higher. Therefore, the requirements for the efficiency and quality of optical lens detection are also getting higher and higher. During the detection process, inspectors use microscopes to inspect yellow spots, black spots, demolding points, scratches, dirt, and bubbles on optical lenses, and finally select qualified good lenses. However, manual detection has the disadvantages of high error rate and slow detection speed. Therefore, the use of machine detection is increasing.

[0004] When using a machine to detect optical lenses, multiple lenses are usually placed in a lens tray, and the lenses in the lens tray are photographed by a camera. Subsequently, the photographed pictures are screened to select good or defective lenses. While the detection efficiency is greatly improved, the misdetection rate is also reduced. The detection speed has increased from 100 - 200 pieces per hour for manual detection to 10,000 - 25,000 pieces per hour, and the detection efficiency has been significantly improved.

[0005] However, with the significant improvement in detection efficiency, the loading speed of the lens tray has also increased significantly. During the long-term detection process, the staff manually transports the lens tray for detection and loading, which brings a relatively large physical burden to the staff. Usually, multiple people take turns to load the lens tray, which not only increases the workload of the staff but also increases the labor cost during the lens detection process.

At this time, start the driving component 5 to drive the support rod 41 to move on the installation rod 4, adjust the position of the support rod 41 on the installation rod 4, so that the lower edge of the push plate 17 is lower than the top of the top - most lens tray 14 but higher than the bottom of the top - most lens tray 14. Then start the driving part 3 to drive the push plate 17 to move towards the conveyor belt 72. The side wall of the push plate 17 abuts against the side wall of the top - most lens tray 14, thereby driving the top - most lens tray 14 to move towards the conveyor belt 72, and finally the lens tray 14 is completely located on the conveyor belt 72 under the conveying action of the push plate 17 and the conveyor belt 72. Subsequently, the lens tray 14 is conveyed to the detection table 13 by the conveying device 7, and the lenses on the lens tray 14 are detected on the detection table 13. After the lens detection is completed, the staff takes the detected lens tray 14 away from the detection table 13. At this time, the detection table 13 is vacated.
