Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically a lens support turntable. Background Technology

[0002] A lens is an optical device primarily used to correct vision or protect the eyes. It is usually made of transparent materials such as glass, resin, or polycarbonate (PC) and has one or more curved surfaces. It can refract light to make objects appear clearly. During lens processing, mechanical operations such as photographing, applying glue, and marking the lens are often required to form a complete lens processing production line to improve production efficiency. Turntables are often used as material carriers in the lens production line process.

[0003] According to patent number CN202320354893.4, a lens processing turntable device includes a turntable, several trays disposed on the top surface of the turntable, a first groove disposed on the bottom side of one side of the trays, a square hole formed in the first groove away from the center of the trays, a pressing component disposed in the first groove, an elastic component horizontally disposed in the first groove and abutting against the pressing component, and several lifting components mounted on the bottom surface of the turntable. The elastic component is located at the end of the first groove away from the center of the trays. The turntable has a first through hole corresponding to the pressing component. The lifting component extends through the first through hole to below the pressing component. The pressing component passes through the square hole and forms a lens clamping position between itself and the trays. The pressing component is obliquely slidably connected to the square hole. This lens processing turntable device clamps and fixes the lens to the trays during lens processing, improving the stability and accuracy of lens processing.

[0004] Existing lens turntables mostly use mechanical bolts to fix the turntable. When disassembling, each bolt must be loosened one by one, which is time-consuming and labor-intensive. Improper operation can easily lead to the loss or damage of parts, making it difficult to meet the needs of frequent maintenance or rapid model change. In addition, traditional turntables rely on a single axis support when rotating. Long-term operation can easily cause shaft deformation or motor overload due to concentrated force, affecting rotation accuracy and equipment life. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a lens support turntable to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens support turntable, comprising a base and a turntable. A control motor is disposed in the middle of the base, a rotating shaft is disposed at the top of the control motor, an electromagnetic chuck is fixedly connected to the top of the rotating shaft, a magnetic plate is fixedly connected to the lower surface of the turntable, a positioning part is disposed in the middle of the lower surface of the turntable, a positioning groove is formed in the middle of the upper surface of the electromagnetic chuck, an annular guide groove is fixedly connected to the upper surface of the base, and a ball bearing is disposed on the lower surface of the electromagnetic chuck.

[0007] Preferably, a lens placement part is provided at the middle of the upper surface of the turntable, and the outer surface of the positioning part is adapted to the inner surface of the positioning groove.

[0008] Preferably, a guide rod is fixedly connected to the side of the upper surface of the turntable, and a lens pressure plate and a connecting plate are sleeved on the outer surface of the guide rod, with the connecting plate located below the lens pressure plate.

[0012] Preferably, the outer surface of the ball is adapted to the interior of the annular guide groove.

[0013] Beneficial effects

[0014] This invention provides a lens support turntable. It has the following beneficial effects:

[0015] (1) The lens support turntable uses the magnetic adsorption of the electromagnetic chuck and the magnetic plate to achieve one-click quick installation and removal of the turntable by simply turning on or off the power. This significantly shortens maintenance time and reduces the intensity of manual operation. Combined with the precise fitting design of the positioning part and the positioning groove, it ensures that the center position is automatically calibrated when the turntable is installed, effectively preventing deflection errors and improving processing accuracy.

[0016] (2) The lens supports the turntable. Through the matching structure of the ball and the annular guide groove, when the electromagnetic chuck rotates, the ball rolls along the guide groove to form multi-point support, which greatly disperses the radial pressure on the turntable, thereby improving the rotational stability and power transmission efficiency, and extending the service life of the turntable and motor.

[0021] 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.

[0022] Example 1:

[0023] like Figs. 1-3 As shown, this utility model provides a lens support turntable, including a base 1 and a turntable 5. A control motor 2 is provided in the middle of the base 1, and a rotating shaft 3 is provided on the top of the control motor 2. An electromagnetic chuck 4 is fixedly connected to the top of the rotating shaft 3. A magnetic plate 7 is fixedly connected to the lower surface of the turntable 5. A positioning part 17 is provided in the middle of the lower surface of the turntable 5. A positioning groove 8 is opened in the middle of the upper surface of the electromagnetic chuck 4. An annular guide groove 9 is fixedly connected to the upper surface of the base 1. A ball bearing 10 is provided on the lower surface of the electromagnetic chuck 4.

[0024] Specifically, a lens placement part 6 is provided in the middle of the upper surface of the turntable 5, and the outer surface of the positioning part 17 is adapted to the inner surface of the positioning groove 8.

[0025] Specifically, a guide rod 11 is fixedly connected to the side of the upper surface of the turntable 5. A lens pressure plate 12 and a connecting plate 13 are sleeved on the outer surface of the guide rod 11. The connecting plate 13 is located below the lens pressure plate 12.

[0026] Specifically, a spring 14 is provided on the outer surface of the guide rod 11. The end of the spring 14 is fixedly connected to the lower surface of the connecting plate 13, and the end of the spring 14 away from the connecting plate 13 is fixedly connected to the upper surface of the turntable 5.

[0027] Specifically, the outer surface of the guide rod 11 is threaded with a fastening nut 15, which is positioned above the lens pressure plate 12.

[0028] Specifically, the upper surface of the connecting plate 13 is rotatably connected to the lower surface of the lens pressure plate 12, and a rubber pad 16 is provided on the side of the lower surface of the lens pressure plate 12.

[0029] Specifically, the outer surface of the ball 10 is adapted to the interior of the annular guide groove 9.

[0030] The working principle and beneficial effects of the above embodiments.

[0031] In use, place the lens on the lens placement part 6. When the spring 14 is at its natural length, the height of the lens pressure plate 12 is lower than the upper surface of the lens placement part 6. Move the lens pressure plate 12 upward until the height of the rubber pad 16 is higher than the lens. The connecting plate 13 moves upward accordingly, and the spring 14 is stretched. Then rotate the lens pressure plate 12 until the rubber pad 16 is above the lens. After releasing the lens pressure plate 12, under the elastic pull of the spring 14, the lens pressure plate 12 presses down on the lens, and the rubber pad 16 contacts the surface of the lens. At this time, the spring 14 is still in the stretched state. The elastic force of the spring 14 makes the lens pressure plate 12 always have downward pressure on the lens, so that the lens is pressed tightly. Repeat the above operation for the other lens pressure plates 12, so that the lens is pressed and fixed by multiple sets of lens pressure plates 12. After the lens is fixed, control the motor 2 to drive the rotating shaft 3 to rotate, which drives the electromagnetic chuck 4 and the turntable 5 to rotate, and the lens moves accordingly. The rotation facilitates processing. During the rotation of the electromagnetic chuck 4, the ball bearing 10 rotates along the annular guide groove 9. The ball bearing 10 and the annular guide groove 9 provide support for the electromagnetic chuck 4 and disperse the pressure on the rotating shaft 3. When it is necessary to remove the lens, rotate the lens pressure plate 12 to deflect it and move it away from the lens placement part 6, thereby releasing the lens pressure plate 12 from fixing the lens. Since the turntable 5 is set to be fixed by the magnetic plate 7 attracted by the energized electromagnetic chuck 4, when the turntable 5 needs to be cleaned or repaired and replaced, the electromagnetic chuck 4 can be de-energized to release the attraction force of the electromagnetic chuck 4 on the magnetic plate 7, and the turntable 5 can be disassembled for cleaning or repair and replacement. When installing the turntable 5, align the positioning part 17 at the bottom of the turntable 5 and insert it into the positioning groove 8, and then energize the electromagnetic chuck 4 so that the electromagnetic chuck 4 magnetically attracts the magnetic plate 7 on the lower surface of the turntable 5, so that the turntable 5 is quickly installed and fixed.
