[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0019] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0020] Example 1: Figure 1-2 As shown, a lens outer edge processing grinding and polishing machine includes a Y-axis linear drive mechanism 100, the lower end of the Y-axis linear drive mechanism 100 is connected to a rotary drive mechanism 200, the rotary drive mechanism 200 is in transmission connection with a pressure rod 201, a support platform 300 is provided at the lower side of the pressure rod 201, the support platform 300 is rotatably provided on a frame 400, a working space for placing the lens to be ground and polished is formed between the support platform 300 and the pressure rod 201, and a grinding and polishing belt 500 is provided on the side of the frame 400 corresponding to the working space.

[0021] In this embodiment, the polishing belt 500 adopts the existing structure, which is wound on two driving wheels installed on the frame 400. During operation, the driving wheels rotate to drive the polishing belt 500 to move, thereby polishing the lenses placed in the working space.

[0022] In a possible implementation, the Y-axis linear drive mechanism 100 is installed on a gantry 600, a pair of slide rails 601 are arranged on the inner side of the gantry 600, a cross plate 602 is arranged between the pair of slide rails 601, the upper end of the cross plate 602 is connected to the push rod of the cylinder 603, and the rotation drive mechanism 200 is arranged at the lower end of the cross plate 602; the rotation drive mechanism 200 can specifically use a stepping motor or a starting motor and other mechanisms, and the rotation drive mechanism 200 is connected to the pressure rod 201 through a coupling.

[0023] During operation, the lens to be polished is placed on the support table 300, and the cylinder 603 is started. The push rod of the cylinder 603 extends to drive the pressure rod 201 under the horizontal plate 602 to move downward, so that the lens is pressed and fixed on the support table 300. In order to avoid crushing the lens, a rubber buffer layer can be covered on the bottom end surface of the support table 300 and the pressure rod 201; the support table 300 is rotatably arranged on the frame 400. When the rotary drive mechanism 200 drives the pressure rod 201 to rotate, the lens located between the pressure rod 201 and the support table 300, and the support table 300 itself can rotate synchronously, thereby realizing the polishing of different positions on the side of the lens.

[0024] Example 2: Figure 3-4 As shown, in order to improve the stability of the lens when it is placed on the support platform 300, a plurality of limiting posts 301 are arranged on the top of the support platform 300. The plurality of limiting posts 301 are arranged to form a recessed placement space. The limiting posts 301 are used to roll in contact with the side of the lens. When the lens is placed in the placement space, the lens contacts the limiting posts 301, and the other side of the lens can extend to the outside of the limiting posts 301 and contact and cooperate with the polishing belt 500 to avoid obstruction to the polishing area of ​​the lens.

[0025] In a possible implementation, three limit posts 301 are provided, and the three limit posts 301 are arranged in an arc shape. The three limit posts 301 can be more evenly distributed on the side of the lens, providing multi-point support, thereby improving the stability of the lens on the support table. In this way, the displacement or vibration of the lens caused by instability during the grinding and polishing process can be reduced, ensuring the uniformity and consistency of the grinding and polishing quality.

[0026] See also Figure 4 In the specific operation, the lens 700 is placed in the placement space of the support table 300, so that the lens 700 contacts the limiting column 301, and the other side of the lens 700 extends to the outside of the limiting column 301, and contacts and cooperates with the polishing belt 500. A bottom plate 302 is further provided in the placement space, and the bottom plate 302 contacts and cooperates with the bottom end of the lens. The diameter of the bottom plate 302 is smaller than the diameter of the lens, so as to prevent the outer edge of the bottom plate 302 from protruding from the lens and affecting the polishing of the bottom end of the lens.

[0027] In order to avoid relative rotation between the lens and the support platform 300 when the lens rotates, thereby increasing the wear on the lens, a chassis 302 is further rotatably provided in the placement space, and the chassis 302 is used to contact and cooperate with the bottom end of the lens. The chassis 302 can rotate synchronously with the lens when the lens rotates, thereby reducing the relative sliding between the lens and the support platform 300, thereby reducing the risk of wear on the bottom of the lens.

[0028] Furthermore, the diameter of the bottom plate 302 is smaller than the diameter of the lens, so as to prevent the outer edge of the bottom plate 302 from protruding out of the lens, thereby affecting the grinding and polishing of the bottom end of the lens.

[0029] The lower end of the support platform 300 is rotatably connected to a base 303, and the lower end of the base 303 is connected to a support rod 304, and the support rod 304 is slidably arranged on the frame 400 along the vertical direction. Specifically, the support rod 304 can be slidably arranged on the frame 400 through a locking slide rail, and the height position of the support platform 300 can be further adjusted during use to achieve grinding and polishing of different areas of the lens in the vertical direction.

[0030] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
