[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-3 A coating machine for optical lenses in this embodiment includes a coating machine body 1 and a linear module 2 installed on the coating machine body 1. The coating machine body 1 adopts an existing coating machine. The coating machine equipment can refer to the coating mechanism of a coating machine for optical lenses in the utility model with announcement number CN219907842U.

[0023] In this embodiment, the linear module 2 is an existing screw module, including a servo motor, a guide rail, a screw and a slide for control, and a loading device for installing an optical lens is provided on the linear module 2.

[0024] It should be noted that the loading device includes a mounting block 3 fixedly mounted on the linear module 2 and a number of clamping rods movably mounted on the mounting block 3, wherein the mounting block 3 is fixedly connected to the top of the slide of the linear module 2, and can complete automatic feeding of the optical lens as the slide moves relative to the guide rail.

[0025] The clamping rod in this embodiment includes a fan-shaped rotating rod 4 and a clamp movably installed on the rotating rod 4, wherein a limiting member 15 is fixedly installed at the end of the rotating rod 4, and a circular ring-shaped gap is recessed in the middle of the mounting block 3. The upper and lower ends of the rotating rod 4 slide in contact with the inner wall of the gap of the mounting block 3, thereby realizing the position limitation of the rotating rod 4.

[0026] It should be noted that a groove 6 is also provided in the gap of the mounting block 3, and a limit member 15 is embedded in the groove 6. The limit member 15 rotates relative to the groove 6. The position of the limit member 15 can be limited by the groove 6, so that the rotating rod 4 is not easy to fall out of the mounting block 3, thereby improving the rotation stability of the rotating rod 4.

[0027] In this embodiment, a slide groove 5 is provided on the top of the rotating rod 4, and the clamp includes a connecting part slidably installed in the slide groove 5, a pre-tightening block 9 fixedly installed on the connecting part, and a clamping block 10 rotatably installed on the pre-tightening block 9. One end of the clamping block 10 is rectangular and used to clamp rectangular optical lenses, and the other end of the clamping block 10 is arc-shaped and used to clamp circular optical lenses, thereby improving the application range of the clamping block 10.

[0028] It can be understood that cotton pads 11 are fixedly installed at both ends of the clamping block 10, and the contact of the cotton pads 11 with the optical lens can reduce damage to the optical lens.

[0029] It should be noted that a step 7 is also fixedly installed on the inner wall of the slide groove 5, and the connecting part includes a slider 8 that slides in contact with the surface of the rotating rod 4, a limit block 13 fixedly connected to the slider 8, and a slide bar 14 fixedly connected to the limit block 13. The slider 8, the limit block 13 and the slide bar 14 are arranged in a stepped shape, the slide bar 14 is slidably connected to the slide groove 5, and the limit block 13 slides in contact with the step 7, so that the sliding stability of the slider 8 relative to the rotating rod 4 is further improved.

[0030] In order to limit the rotation of the clamping block 10 relative to the sliding block 8, a threaded handle 12 that passes through the clamping block 10 is threadedly installed on the preload block 9 in this embodiment. The middle part of the clamping block 10 is perforated so that the clamping block 10 and the threaded handle 12 do not contact each other. The threaded handle 12 is divided into an axial part and an end part. The axial part is used to contact the slide groove 5, and the end part is used to contact the clamping block 10. At the same time, the end diameter of the threaded handle 12 is larger than the diameter of the perforated hole on the clamping block 10, so that the threaded handle 12 can abut against the clamping block 10 when it is rotated downward, thereby limiting the position of the clamping block 10. The length of the threaded handle 12 is selected to correspond to the length of the slide groove 5 of the rotating rod 4, so that the lower end of the threaded handle 12 can abut against the slide groove 5 while abutting against the clamping block 10.

[0031] The working principle of the above embodiment is:

[0032] By placing the optical lens above the mounting block 3, according to the shape of the optical lens, for example, if the optical lens is round, several rotating rods 4 are evenly rotated relative to the mounting block 3 in a circular shape, and then the clamp block 10 is rotated relative to the slider 8 so that the arc surface on the clamp block 10 corresponds to the optical lens. Then, the position of the clamp block 10 is changed by sliding the slider 8 on the surface of the rotating rod 4. After the clamp block 10 is abutted against the optical lens, the threaded handle 12 at the top of the clamp block 10 is rotated. The threaded handle 12 is rotated relative to the pre-tightening block 9 and moves down to abut against the rotating rod 4, thereby locking the orientation and position of the clamp block 10, thereby completing the position restriction of optical lenses of different shapes.

[0033] By setting a clamp for fixing the optical lens so that the rotating rod 4 is rotated on the mounting block 3, the distribution of the rotating rod 4 can be flexibly adjusted, so that the rotating rod 4 can be used corresponding to optical lenses of different shapes. For example, when corresponding to a rectangle, the rotating rod 4 can be divided into four parts corresponding to the four sides of the optical lens. When corresponding to a circle, the rotating rod 4 can be distributed in a circular shape corresponding to the outer ring of the optical lens, thereby improving the practicability of the device.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
