Description

Technical Field

[0001] This invention relates to the field of lens manufacturing and processing technology, specifically a rotating device for producing decorative lenses. Background Technology

[0002] The rotating device used for producing decorative lenses is the core equipment for achieving uniform processing and precise positioning in the manufacturing process of decorative lenses. During the lens production process, the lens is transported to the location of each processing component through the conveyor rail and silicone vacuum suction cup. By adding a rotating device between the conveyor rail and the silicone vacuum suction cup, the rotation angle of the lens in the horizontal and axial directions can be adjusted according to different production and processing needs, thereby improving the production and processing efficiency of the lens.

[0003] In the existing technology, during the production and processing of lenses for floor mirrors, the lenses are usually transported along the production line using a combination of motors and gears, with the rotation angle of the lenses being judged manually. This can lead to inconsistent polishing levels at the edges and corners of the lenses during the polishing process, which in turn affects the subsequent framing operation. Summary of the Invention

[0011] As a further aspect of the present invention: the positioning mechanism includes an L-shaped rod, which is slidably connected to the middle of the inner cavity of the through groove. A driven plate is fixedly connected to one end of the L-shaped rod near the drive plate, and a limiting block is fixedly connected to the lower part of the side of the L-shaped rod away from the driven plate.

[0029] Please see Figure 1-6 In this embodiment of the invention, a rotating device for producing decorative lenses includes a bracket 1. A rotating rod 2 is fixedly connected to the upper middle part of the bracket 1. An installation platform 3 is rotatably connected to the upper end of the rotating rod 2. A through groove 42 is provided in the middle of the installation platform 3. A positioning mechanism for limiting the angle of the rotating rod 2 is provided in the inner cavity of the through groove 42. An installation plate 9 is fixedly connected to one side of the lower part of the installation platform 3. A rotating mechanism for driving the rotating rod 2 to rotate is provided on the side of the installation plate 9 near the rotating rod 2. A baffle 26 is fixedly connected to the other side of the installation plate 9. The baffle 26 is fixedly connected to the installation platform 3. When the rotating mechanism is horizontally close to the center of the rotating rod 2, the positioning mechanism moves away from the center of the rotating rod 2, and the rotating rod 2 rotates 45° or 90°.

[0030] Please see Figure 4-5The side wall of the mounting platform 3 is fixedly connected to symmetrical connecting plates 7. A drive shaft 8 is fixedly connected to the upper end of the symmetrical connecting plates 7. A connecting frame 4 is rotatably connected to the outer wall of the drive shaft 8. A fixing rod 5 is fixedly connected to the upper middle part of the connecting frame 4. A fixing plate 6 is fixedly connected to the upper end of the fixing rod 5. Symmetrical drive rollers are provided on the top of the fixing plate 6. The symmetrical drive rollers are connected to the conveyor guide rail. The conveyor guide rail is a mechanical structure used in industrial automation for directional conveying, positioning, or guiding the movement of materials / workpieces. It is usually used in conjunction with conveyor lines, robotic arms, or assembly systems and is a commonly used technical means in the prior art. By driving the drive rollers to rotate via a motor, the fixing plate 6 can be driven along the conveyor guide rail. The slide rail has several silicone vacuum suction cups fixedly connected to the lower two sides of the bracket 1. The decorative lens for the floor mirror is adsorbed and fixed by the silicone vacuum suction cups, and then the lens is transported along the conveyor rail to various working parts of the production line for production and processing. For example, the lens is transported to the grinding mechanism by the conveyor rail to grind the edges and corners of the lens. After grinding, the lens is transported to the inspection mechanism to check the edges, corners and whether the lens is intact. During the further grinding and quality inspection of the lens, the lens needs to be rotated to facilitate grinding and inspection of all four sides of the lens.

[0031] Please see Figure 4-6 A driven gear 11 is fixedly connected to the upper outer wall of the rotating rod 2. The rotating mechanism includes a drive plate 13, which is slidably connected to the mounting plate 9. A cavity 15 is formed on the side of the drive plate 13 near the rotating rod 2. A drive rack 10 is provided inside the cavity 15, and the drive rack 10 meshes with the driven gear 11. An extension plate 14 is fixedly connected to the outer wall of the drive plate 13 away from the rotating rod 2. A first electric push rod 12 is drivenly connected to the outer wall of the mounting plate 9. The output end of the first electric push rod 12 is fixedly connected to the extension plate 14, so that the first electric push rod can be driven through the extension plate 14. The push rod 12 drives the extension plate 14 to move horizontally, thereby driving the drive rack 10 to move horizontally through the drive plate 13. During this process, the drive rack 10 will contact the outer wall of the driven gear 11 and drive the driven gear 11 to rotate, thereby driving the rotating rod 2 and the bracket 1 to rotate. The bottom of the inner cavity of the cavity 15 is slidably connected to the positioning rod 16, which is slidably connected to the middle of the lower end of the drive rack 10. That is, the drive rack 10 can slide horizontally on the outer wall of the positioning rod 16. The length of the positioning rod 16 is 1.5 times the length of the drive rack 10.

[0032] Please see Figure 8When the drive rack 10 and the positioning rod 16 are in contact with each other at the ends away from the extension plate 14, the entire drive rack 10 will contact the driven gear 11 during the horizontal movement of the drive plate 13 along with the extension plate 14. This will drive the driven gear 11 to rotate 90°, which in turn will drive the rotating rod 2 and the bracket 1 to rotate 90° synchronously. At this time, the lens can be rotated 90° in the horizontal direction. When the drive rack 10 and the positioning rod 16 are in contact with each other at the ends close to the extension plate 14, the drive plate 13 will drive the drive rack 10 to move horizontally. During operation, only half of the length of the drive rack 10 contacts the driven gear 11, thereby driving the driven gear 11 and the rotating rod 2 to rotate 45°. At this time, the lens can be rotated 45° in the horizontal direction. For example, when polishing, if it is necessary to polish the edges and corners of the lens, the lens can be driven to rotate 45° to polish the edges and corners of the lens in sequence. When it is only necessary to polish the four sides of the lens, the lens can be driven to rotate 90° to polish the four sides of the lens in sequence.

[0033] Please see Figure 6 and Figure 8 A second electric push rod 19 is connected to the middle of the side of the drive plate 13 away from the rotating rod 2. A connecting rod 17 is slidably connected to the middle of the side of the drive rack 10 near the second electric push rod 19. A groove 18 is opened in the middle of the inner cavity of the cavity 15 away from the rotating rod 2. The connecting rod 17 is slidably connected in the groove 18. The end of the connecting rod 17 away from the drive rack 10 is fixedly connected to the output end of the second electric push rod 19. Through the sliding cooperation between the connecting rod 17 and the drive rack 10, that is, when the second electric push rod 19 drives the connecting rod 17 to move along the groove 18, it will simultaneously drive the drive rack 10 to the positioning rod. The drive rack 10 and driven gear 11 are moved upwards, thereby changing the contact length between the drive plate 13 and the extended plate 14 during the movement of the drive plate 13, and thus changing the angle of horizontal rotation of the lens. During the polishing or visual inspection of the lens, the lens needs to maintain its position after rotating at a certain angle. This requires the drive rack 10 to stop driving the driven gear 11 to rotate during the reset process, and the driven gear 11 to remain stationary after rotating 45° or 90°. In this invention, a positioning mechanism is set to ensure that the driven gear 11 remains stationary after a single rotation.

[0034] Please see Figure 6The positioning mechanism includes an L-shaped rod 29, which is slidably connected to the middle of the inner cavity of the through groove 42. A driven plate 28 is fixedly connected to one end of the L-shaped rod 29 near the drive plate 13. A limiting block 30 is fixedly connected to the lower part of the side of the L-shaped rod 29 away from the driven plate 28. The limiting block 30 engages with the driven gear 11 to fix the position of the driven gear 11. The end of the L-shaped rod 29 away from the driven plate 28 is elastically connected to the inner cavity sidewall of the through groove 42 by a spring. The spring allows the limiting block 30 to remain engaged with the driven gear 11. However, during the lens polishing process, the lens will be subjected to pressure and vibration, which makes the limiting effect of the elastic engagement unstable. A drive rod 27 is fixedly connected to the upper end of the drive plate 13 near the driven gear 11. The end of the drive rod 27 away from the drive plate 13 extends into the inner cavity of the through groove 42.

[0035] Please see Figure 6-7 A first groove 31 is formed on the lower end of the driven plate 28 near the L-shaped rod 29, and a second groove 32 is formed on the lower end of the driven plate 28 away from the L-shaped rod 29. A reset groove 33 and an inclined groove 34 are formed between the second groove 32 and the first groove 31, connecting the first groove 31 and the second groove 32. The inclined groove 34 is driven to approach the position of the extension plate 14. The length of the second groove 32 is less than the length of the first groove 31. The outer wall of the end of the drive rod 27 away from the drive plate 13 slides in cooperation with the first groove 31, the second groove 32, the reset groove 33, and the inclined groove 34. When the drive rod 27 is located at the end of the inner cavity of the first groove 31 away from the reset groove 33, the limiting block 30 engages with the driven gear 11. With the cooperation of the inner cavity of slot 1 31, the driven plate 28 remains stationary, so the L-shaped rod 29 and the limiting block 30 cannot move, allowing the limiting block 30 to stably limit and fix the driven gear 11. The connection between slot 1 31 and inclined groove 34 is elastically connected to an inclined block 35. An inclined surface is opened at the end of the inclined block 35 near the reset groove 33, so that when the drive rod 27 moves in the inner cavity of slot 1 31, it cannot move directly to the position of the reset groove 33. Instead, with the cooperation of the inclined block 35 and the inclined groove 34, it will enter the second slot 32 through the inner cavity of the inclined groove 34. At this time, the driven plate 28, L-shaped rod 29 and limiting block 30 will move horizontally away from the position of the reset groove 33, thereby releasing the limiting block 30 from limiting the driven gear 11.

[0036] After the drive rod 27 enters the inner cavity of the second slot 32, the drive rack 10 will contact the driven gear 11. After the limiting block 30 separates from the driven gear 11, the drive rack 10 will drive the driven gear 11 to rotate, thus avoiding the presence of the limiting block 30 affecting the movement of the drive rack 10. When the drive rod 27 moves to the connection between the second slot 32 and the reset slot 33, the limiting block 30, the L-shaped rod 29 and the driven plate 28 will be reset under the action of the elastic force. The drive rod 27 will return to the inner cavity of the first slot 31, and the limiting block 30 will be engaged with the outer wall of the driven gear 11 again. During the reset process of the drive rod 27, it will continue to maintain a stable limiting effect on the driven plate 28, thus preventing the lens angle from changing during the grinding process. The wedge block 35 will not obstruct the reset process of the drive rod 27. During the reset process of the drive rod 27, it will contact the inclined surface of the wedge block 35, thereby squeezing the wedge block 35 towards the top of the driven plate 28.

[0037] Please see Figure 9-10 A movable rod 21 is fixedly connected to the lower middle part of the positioning rod 16. A horizontal groove 20 that slides with the movable rod 21 is opened at the lower end of the drive plate 13. A symmetrical connecting groove 24 and a balance groove 25 are opened at the upper end of the mounting plate 9 (the balance groove 25 near the driven gear 11 is referred to as the first balance groove 25, and the one further away is the second balance groove 25; the one near the extension plate 14 is the first connecting groove 24, and the one further away is the second connecting groove 24). When the extension plate 14 is in the initial position, the movable rod 21 is located at the connection between the first balance groove 25 and the first connecting groove 24. During the horizontal movement of the drive plate 13 driven by the extension plate 14, the movable rod 21 will move in the inner cavity of the first balance groove 25. A groove 22 is opened at the connection between the first balance groove 25 and the second connecting groove 24, as well as at the connection between the second balance groove 25 and the first connecting groove 24. A movable plate 23 is elastically connected to the inner cavity of the groove 22. An inclined edge is opened on the side of the movable plate 23 near the balance groove 25.

[0038] Please see Figure 10As the movable rod 21 moves toward the connection between the balance groove 25 and the connecting groove 24, it approaches and eventually contacts the inclined side. At this point, the action of the outer wall of the movable rod 21 and the inclined side pushes the movable plate 23 into the inner cavity of the groove 22. When the outer wall of the movable rod 21 contacts the side wall of the movable plate 23 away from the groove 22, the movable plate 23 resets under the action of elasticity, thus pushing the movable rod 21 toward the inner cavity of the second balance groove 25. This causes the positioning rod 16 and the drive rack 10 to simultaneously retract into the inner cavity of the cavity 15, thereby completing the separation of the drive rack 10 and the driven gear 11. Since the connecting rod 17 is slidably connected to the drive rack 10, it will not hinder the lateral movement of the drive rack 10. Therefore, the drive rack 10 will remain retracted into the cavity 15. As the drive plate 13 resets, the driven gear 11 will not be driven to rotate during the reset process of the drive rack 10, so that the driven gear 11 can only rotate intermittently in one direction. When the movable rod 21 moves to the second balance groove 25 and the first connecting groove 24, it will return to the initial position under the action of the movable plate 23, so that the drive rack 10 will only extend out of the cavity 15 after it is far away from the position of the driven gear 11.

[0039] Please see Figure 6-8 Through the cooperation of the drive rod 27 with slot 31, slot 32, inclined slot 34, and inclined block 35, as the drive rod 27 moves with the drive plate 13, before the drive rack 10 contacts the driven gear 11, the drive rod 27 drives the driven plate 28 to move. This causes the limiting block 30 to separate from the driven gear 11 before the drive rack 10 contacts it. Furthermore, as the drive rack 10 drives the driven gear 11 to rotate, the limiting block 30 remains separated from the driven gear 11. After the driven gear 11 rotates 45° or 90°, the limiting block 30 automatically moves closer to the driven gear 11. And engage with it. After the drive rack 10 drives the driven gear 11 to rotate, it will automatically retract into the inner cavity of the cavity 15 under the action of the movable plate 23. During the reset of the drive plate 13, the drive rack 10 remains separated from the driven gear 11, while the limit block 30 remains in close contact with the driven gear 11. This allows the lens to maintain its rotated state after rotating 45° or 90° and no longer move, thus achieving the effect of intermittently driving the lens to rotate. During the process of conveying the lens along the production line, the rotation angle of the lens can be controlled at any time according to the needs of production and processing, which is convenient for lens processing.

[0040] Please see Figure 4-5A servo motor 36 is connected to the upper end of the connecting frame 4 near the connecting plate 7. A first gear 37 is fixedly connected to the output end of the servo motor 36. A driven frame 39 is horizontally slidably connected to the side wall of the connecting frame 4. A first rack 38 is fixedly connected to the middle of the upper end of the driven frame 39. The first rack 38 meshes with the first gear 37. A symmetrical second rack 41 is fixedly connected to the top of the inner cavity of the driven frame 39. A symmetrical second gear 40 is fixedly connected to the outer wall of the transmission shaft 8. The second gear 40 is located between the connecting plate 7 and the connecting frame 4. When the center of the driven frame 39 coincides with the center of the transmission shaft 8, the symmetrical second rack 41 separates from the second gear 40. When the servo motor 36 drives the first gear 37 to rotate, the first gear 37 will drive the driven frame 39 to move horizontally through its engagement with the first rack 38. This drives the connecting plate 7, drive shaft 8, mounting platform 3, rotating rod 2, and bracket 1 to rotate axially from 0 to 90 degrees. The specific angle depends on the horizontal movement distance of the driven frame 39. This allows the lens to rotate axially from 0 to 90 degrees, facilitating chamfering of the lens and axial rotation of 90 degrees, which is convenient for visual inspection and polishing of the lens surface. Vertical conveying refers to placing multiple lenses vertically after lens production and processing to avoid large lenses being deformed by pressure when laid flat. At this time, rotating the lens axially by 90 degrees allows the lens to be unloaded in a vertical state. Simultaneously, the drive rack 10 intermittently drives the lens to rotate 90 degrees, allowing selection of whether the lens is unloaded with its long side or short side at the bottom, depending on the subsequent conveying tools.

[0041] When chamfering the lens edges, the driven frame 39 is moved horizontally a certain distance by the servo motor 36. The axial rotation angle of the lens is judged manually. Although manual judgment cannot determine the exact degree of the angle, all four edges of a single lens will be chamfered at the same angle. The symmetrical arrangement of the second rack 41 ensures that the lens does not rotate axially when the symmetrical second racks 41 are not in contact with the second gear 40. This allows the lens to maintain a stable horizontal position under its own weight, and the maximum axial rotation angle of the lens in one direction is a fixed 90°, which is sufficient to complete the lens surface inspection and vertical unloading. During horizontal rotation, it can only rotate 45° or 90° in one direction at a time. The electric push rod 12 drives the extension plate 14 to reciprocate in the horizontal direction, which in turn drives the drive rack 10, driven gear 11 and limit block 30 to cooperate, driving the lens to perform unidirectional intermittent rotation in the horizontal direction. When adjusting the horizontal rotation angle, it is only necessary to drive the connecting rod 17 to move through the second electric push rod 19, thereby driving the drive rack 10 to move to both ends of the positioning rod 16, which can quickly complete the adjustment of a single rotation angle. After rotation, a stable limit can be obtained immediately, ensuring that the lens can stably maintain the rotated state during the production process. Furthermore, during the lens conveying process on the production line, the lens angle can be rotated in advance before the lens enters the next process, thereby saving overall production time.
