Description

Technical Field

[0001] This utility model relates to the field of lens marking technology, specifically a lens marking machine fixture. Background Technology

[0002] A lens marking machine is a device that uses laser technology for marking. It is mainly used to engrave and cut out fine text and patterns on eyeglass lenses. Lens marking machines are often called CO2 laser marking machines or ultraviolet laser marking machines, and are suitable for various eyeglass lenses, plastics, ceramics, glass and other non-metallic materials.

[0003] According to patent number CN202323450543.7, a fixture for a lens marking machine includes a worktable with a mounting plate. Two mounting blocks are movably mounted on the mounting plate, and a transmission mechanism is also provided. The transmission mechanism can drive the two mounting blocks to move closer or further apart. Each mounting block has a clamping block with a clamping groove that matches the lens's baffle. The two clamping blocks are used to clamp the two baffles on both sides of the lens. By clamping the two baffles of the lens with the two clamping blocks, the lens can be easily held, facilitating installation. The clamping grooves on the clamping blocks, which match the baffles, ensure stable clamping. Furthermore, the two clamping blocks can move relative to each other under the action of the transmission mechanism, adapting to lenses of different sizes.

[0004] When marking lenses, dust and other contaminants may adhere to the surface of the lens, which can cause laser loss during marking and thus affect the marking effect. Therefore, the lens needs to be cleaned before marking. However, the existing lens marking machine fixtures have relatively simple functions, and the operation of cleaning the lens is usually done manually, which is inefficient. Therefore, a lens marking machine fixture is proposed to add the function of cleaning the lens. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a lens marking machine fixture. It has the following beneficial effects:

[0015] (1) The lens marking machine fixture, through the cooperation between the second electric cylinder, the cleaning mechanism and the limiting plate, enables the fixture to have the function of cleaning the lens.

[0025] Specifically, a first spring 905 is sleeved on the outer surface of the first movable rod 904, a first magnetic plate 906 is provided at the bottom end of the first movable rod 904, and a second magnetic plate 908 is provided at the side of the outer surface of the fixed shaft 902.

[0026] Specifically, the end of the lead screw 3 away from the stepper motor 2 is rotatably connected to the inner surface of the base 1, and the first clamping block 7 is positioned opposite the second clamping block 11.

[0027] Specifically, the outer surface of the fixing block 901 is fixedly installed at the output end of the second electric cylinder 8, and the second magnetic plate 908 is set at both ends of the microfiber cloth 907.

[0028] Specifically, the end of the first spring 905 is fixedly connected to the upper surface of the first magnetic plate 906, and the end of the first spring 905 away from the first magnetic plate 906 is fixedly connected to the bottom end of the connecting rod 903.

[0029] Specifically, the fixed shaft 902 has internal grooves 909 at both ends, and a second movable rod 910 is sleeved on the inner surface of the internal groove 909. A fixed ball 912 is fixedly connected to the end of the second movable rod 910.

[0030] Specifically, a second spring 911 is fixedly connected to the end of the second movable rod 910 away from the fixed ball 912. The second spring 911 is disposed in the inner cavity of the inner groove 909, and the end of the second spring 911 away from the second movable rod 910 is fixedly connected to the inner surface of the inner groove 909.

[0031] The working principle and beneficial effects of the above embodiments.

[0032] In use, a tubular microfiber cloth 907 moistened with detergent is placed on the fixed shaft 902. The fixed shaft 902 is then attracted to the first magnetic plate 906 at the bottom of the first movable rod 904 via the second magnetic plate 908, completing the assembly of the cleaning mechanism 9. Initially, the second electric cylinder 8 is retracted to its shortest position. The lens is placed at the second clamping block 11, and the first electric cylinder 6 is driven to extend, causing the first clamping block 7 to move to the lens and work with the second clamping block 11 to clamp the lens. After the lens is fixed, the second electric cylinder 8 is extended, causing the cleaning mechanism 9 to move on the lens. Under the action of gravity, the first movable rod 904 and the first spring 905 extend, causing the microfiber cloth 907 to adhere to the surface of the lens. The second electric cylinder 8 drives the microfiber cloth 907 to move along the lens from one side of the first clamping block 7 to one side of the second clamping block 11, until it moves into the limiting plate 12. When the fixed shaft 902 moves to the limiting plate 12, the fixed ball 912 and The second movable rod 910 is squeezed by the limiting plate 12, causing it to move inward along the inner groove 909. The second spring 911 is compressed. When the fixed ball 912 moves to the groove of the limiting plate 12, the fixed ball 912 and the second movable rod 910 are stuck in the groove of the limiting plate 12 under the elastic force of the second spring 911. At this time, the second electric cylinder 8 is shortened. Under the restriction of the limiting plate 12, the first magnetic plate 906 and the second magnetic plate 908 are separated until the second electric cylinder 8 is shortened to its shortest length. The connecting rod 903 module is above the first clamping block 7 so that it does not block the lens. The module consisting of the fixed shaft 902 and the microfiber cloth 907 remains in the limiting plate 12, completing the step of unidirectional lens wiping. After cleaning the dust off the lens, the lens is then marked. By controlling the stepper motor 2, the lead screw 3 drives the slider 4 to move, thereby allowing fine adjustment of the position of the clamped lens, which facilitates the marking machine to accurately mark the lens.
