[0002] Smart glasses refer to wearable eyewear devices that, like smartphones, have their own operating systems and can perform various functions through software installation. They are among the most promising wearable smart devices proposed in recent years. They are characterized by ease of use and small size, and the public generally believes that the emergence of smart glasses will make people's lives more convenient.

[0003] During the manufacturing process of smart glasses, the lenses need to be installed on the frame. After dispensing and mounting, pressure holding is required. For workpieces such as lenses that are not completely flat due to curvature, the existing pressure holding mechanism has a fixed structure, which may cause uneven force on the workpiece and lead to friction damage. Therefore, a lens pressure holding mechanism with an adaptive adjustment module is needed. Utility Model Content

[0004] The purpose of this invention is to provide a lens pressure holding mechanism with an adaptive adjustment module, which can adaptively adjust the pressing angle of a workpiece with a certain curvature to ensure that it is pressed down horizontally and evenly, protect the workpiece, and effectively prevent deviation or rebound during the pressure holding process, thereby improving the production quality and efficiency of lenses.

A carrier plate is fixedly connected to the moving platform of the linear module. An XYZ adjustment slide is provided on the frame. An electric cylinder is fixedly connected to the moving platform of the XYZ adjustment slide. An adaptive adjustment module is fixedly connected to the telescopic rod of the electric cylinder. The adaptive adjustment module includes an upper base plate, an adjustment column, a spring, a connecting rod, a lower base plate, and a pressure-holding head. Limit grooves are provided on both the upper and lower base plates. The spring is located between the upper and lower base plates. The upper and lower base plates are respectively provided with an upper countersunk hole and a lower countersunk hole. The minimum diameter of the upper countersunk hole is larger than the diameter of the threaded section of the adjustment column. The adjustment column and the connecting rod are respectively located in the upper countersunk hole and the lower countersunk hole. The connecting rod is threadedly connected to the adjustment column.

[0006] Furthermore, a positioning post and a vacuum suction cup are fixedly connected to the carrier plate, and the vacuum suction cup and the positioning post are offset from each other.

[0007] Furthermore, the upper seat plate is fixedly connected to the telescopic rod of the electric cylinder, the upper seat plate and the lower seat plate are arranged parallel to each other, and the pressure holding head is fixedly connected to the lower seat plate.

[0008] Furthermore, the pressure holding head is a contour block, and the pressure holding head is made of polyurethane.

[0009] The beneficial effects of this utility model are: it can adaptively adjust the pressing angle of a workpiece with a certain curvature to ensure that it is pressed down horizontally and evenly, protect the workpiece, and effectively prevent the deviation or rebound phenomenon during the pressure holding process, thereby improving the production quality and efficiency of the lens.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0015] refer to Figures 1-3 The illustrated lens pressure-holding mechanism with an adaptive adjustment module includes a frame 1 and a linear module 2. A carrier plate 3 is fixedly connected to the moving platform of the linear module 2. An XYZ adjustment slide 4 is provided on the frame 1. An electric cylinder 5 is fixedly connected to the moving platform of the XYZ adjustment slide 4. The XYZ adjustment slide 4 can adjust the position of the electric cylinder 5. An adaptive adjustment module is fixedly connected to the telescopic rod of the electric cylinder 5. The adaptive adjustment module includes an upper base plate 601, an adjustment column 602, a spring 603, and a connecting... The upper seat plate 601 and the lower seat plate 605 are equipped with limit grooves. The spring 603 is located between the upper seat plate 601 and the lower seat plate 605. The upper seat plate 601 and the lower seat plate 605 are respectively provided with upper countersunk holes and lower countersunk holes. The minimum diameter of the upper countersunk hole is larger than the diameter of the threaded section of the adjusting column 602. The adjusting column 602 and the connecting rod 604 are respectively located in the upper countersunk hole and the lower countersunk hole. The connecting rod 604 is threadedly connected to the adjusting column 602.

[0016] The carrier plate 3 is fixedly connected to a positioning post 301 and a vacuum suction cup 302. The positioning post 301 is used to position and place the carrier. The vacuum suction cup 302 is offset from the positioning post 301 and is used to adsorb and fix the carrier.

[0017] The upper seat plate 601 is fixedly connected to the telescopic rod of the electric cylinder 5. The electric cylinder 5 is used to drive the upper seat plate 601 to rise and fall. The upper seat plate 601 and the lower seat plate 605 are arranged in parallel. The pressure holding head 606 is fixedly connected to the lower seat plate 605.

[0018] The pressure holding head 606 is a contour block, and the pressure holding head 606 is made of polyurethane.

[0019] The working principle of this utility model is as follows: When in use, the carrier that loads the lens and frame is placed on the carrier plate 3 along the positioning post 301 and fixed by vacuum suction cup 302. Then, the electric cylinder 5 drives the adaptive adjustment module to descend. After the pressure holding head 606 contacts the lens, it will automatically adjust its angle to fit the lens and maintain pressure under the cooperation of spring 603 and adjustment post 602 (during the pressing process, the lower seat plate 605, connecting post 602 and adjustment post 602 can move upward and deflect ±5° relative to the upper seat plate 601).
