Abstract
Description
Technical Field
[0001] This utility model relates to the field of contact lenses, specifically a laser marking machine for contact lenses. Background Technology
[0002] Contact lenses, also known as contact lenses, are medical devices placed directly on the surface of the cornea of the eye to correct vision or protect the eyes. During the manufacturing process, contact lenses require laser marking. Generally, soft contact lenses are not marked, but astigmatic lenses are marked with horizontal or vertical marks. Sometimes, codes such as base curve, diameter, and brand are also marked on the lens. Laser marking machines use a laser beam to create permanent marks on the surface of contact lenses, which plays an important role in product identification and anti-counterfeiting.
[0003] Contact lenses are usually stored in contact lens cases. During the laser marking process of contact lenses, the contact lens case is usually clamped and fixed, and then the contact lenses are marked by laser marking machine 3. Although this fixing method is relatively stable, after the contact lens is processed, it is necessary to remove and fix the next contact lens case. This process is cumbersome and reduces the efficiency of marking individual lenses. Therefore, a contact lens laser marking machine is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laser marking machine for contact lenses. It offers advantages such as convenient fixing and retrieval of contact lenses, and increased efficiency in marking contact lenses. It solves the problem that contact lenses are typically stored in contact lens cases, and during laser marking, the cases are usually held in place with clips before the laser marking machine marks the lenses. While this method is relatively stable, it requires removing and re-fixing the case after each lens is processed, which is cumbersome and reduces the efficiency of marking individual lenses.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0017] Furthermore, both pressure plates are arranged in a U-shape facing opposite directions, and both rotating blocks are arranged tilted outwards.
[0018] The advantages of adopting the above-mentioned further solution are that the U-shaped pressure plate will press and limit the two sides of the contact lens case, and the hollow part between them will not affect the laser marking of the contact lens.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figure 1-4The present invention discloses a laser marking machine for contact lenses. The present invention includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a laser marking machine 3 fixedly connected to the top of the support frame 2, a support plate 4 fixedly connected to the outer side of the support frame 2, a motor 5 fixedly connected to the bottom of the support plate 4, a placement plate 6 rotatably connected to the outer side of the output shaft of the motor 5, a partition plate 7 fixedly connected to the top of the placement plate 6, first electric push rods 8 fixedly connected to both the front and rear sides of the partition plate 7, rotating blocks 9 slidably connected to the opposite sides of the two first electric push rods 8, pressure plates 10 fixedly connected to the outer side of the two rotating blocks 9, two placement slots symmetrically distributed front and back are opened inside the placement plate 6, and a clearance slot is opened inside the two placement slots, a second electric push rod 11 fixedly connected to the top of the support plate 4, and a push plate 12 fixedly connected to the top of the second electric push rod 11.
[0028] The support plate 4 has an annular groove inside, and the bottom of the placement plate 6 is fixedly connected to an annular plate 15 that is slidably connected to the annular groove.
[0029] In this embodiment, during actual use, the starting of the motor 5 can drive the placement plate 6 to rotate, thereby causing the annular plate 15 below the placement plate 6 to slide in the annular groove, so as to provide the rotation direction and support force of the placement plate 6.
[0030] Both rotating blocks 9 are rotatably connected to the placement plate 6, and the rear placement slot is located directly below the laser marking machine 3.
[0031] In this embodiment, during actual use, the rotating block 9 can rotate under the push of the first electric push rod 8, and the laser marking machine 3 can mark the contact lens inside the placement slot on the rear side.
[0032] The two rotating blocks 9 each have a sliding groove inside, and the two second electric push rods 11 are fixedly connected to the opposite sides of each other with a connecting rod 13. The two connecting rods 13 are rotatably connected to rollers 14 that are slidably connected to the two sliding grooves respectively.
[0033] In this embodiment, during actual use, activating the second electric push rod 11 causes the connecting rod 13 to extend and push the roller 14 to slide inside the groove. The sliding roller 14 pushes the rotating block 9 to rotate, thereby ensuring the downward pressure of the pressure plate 10.
[0034] The two pressure plates 10 are arranged in a U-shape facing opposite directions, and the two rotating blocks 9 are both inclined outwards.
[0035] In this embodiment, during actual use, the U-shaped pressure plate 10 will leave a middle position, and the pressure plate 10 will press and limit the contact lens box in the placement groove without blocking the contact lens, so as to facilitate the laser marking machine 3 to mark the contact lens. When the tilted rotating block 9 is pushed by the first electric push rod 8, the roller 14 inside it moves more smoothly.
[0036] The cross-sectional area of the clearance groove is smaller than that of the placement groove, the cross-sectional area of the push plate 12 is smaller than that of the clearance groove, and the push plate 12 is located below the front clearance groove.
[0037] In this embodiment, during actual use, the contact lens case can be placed in the placement slot. Because the clearance slot hole is small, the contact lens case in the placement slot will not fall downwards. After the contact lens is processed, the push plate 12 can be raised by activating the second electric push rod 11, and the push plate 12 can lift the contact lens case, making it easier to remove the processed contact lens case.
[0038] Working principle:
[0039] When processing and marking contact lenses, firstly, the contact lens case containing the contact lens is placed in the front placement slot. The contact lens case and placement slot are attached together and protected from falling downwards by the clearance slot. Then, the first electric push rod 8 on the front is activated. The first electric push rod 8 causes the roller 14 to slide within the rotating block 9 and rotates the rotating block 9, thereby causing the pressure plate 10 to press down and fix the contact lens case. The contact lens is then located inside the contact lens case and is not obstructed by the U-shaped pressure plate 10. Subsequently, the motor 5 is activated to move the placement plate 6. The contact lens is rotated, and the contact lens inside the rotating placement plate 6 is laser-marked by the laser marking machine 3 above. The clearance slot from back to front can be used to place a new contact lens box for laser marking. The process of placing the contact lens box, pressing down the pressure plate 10, rotating the placement plate 6, raising the pressure plate 10, and activating the second electric push rod 11 to push out the push plate 12 and remove the contact lens completes the marking of the contact lens. The loading and unloading of the contact lens is accelerated by the time the laser marking machine 3 marks the contact lens after the rotation of the placement plate 6.
