Description

Technical Field

[0001] The invention relates to the technical field of mechanical polishing equipment, and in particular to a single-stage driving device for polishing the periphery of an optical lens. Background Art

[0002] Traditional lens polishing equipment usually consists of multiple independent functional modules, which rely on their own drive systems when performing operations such as lens holding, rotation, polishing wheel driving and displacement. This decentralized design can still meet basic needs in small-scale production or scenarios where lens precision is not too high in the past. However, as the modern optical industry develops towards large-scale, high-precision and high-efficiency, traditional equipment has exposed many limitations. On the one hand, multiple independent drive systems lead to a complex overall structure and bulky size of the equipment, which not only occupies a large amount of production space, but also increases the manufacturing cost and maintenance difficulty of the equipment. On the other hand, the synergy between the functional modules is poor. Due to the lack of a unified power source and a precise linkage control mechanism, in the actual polishing process, problems such as asynchronous lens holding and rotation, and mismatch between polishing wheel displacement and lens position are prone to occur, which seriously affect the polishing quality and production efficiency of the lens.

[0003] The lens polishing equipment commonly found on the market today is difficult to achieve efficient coordinated operation as designed by the present invention. For example, after the gripping action is completed, the polishing wheel may not be in place in time for polishing due to delays and incoordination between the various drive systems. For the motion control of the polishing wheel, existing equipment lacks the ability to adaptively coordinate changes in the peripheral size of the lens. When the outer diameter of the lens changes, it is difficult for traditional equipment to automatically adjust the position of the polishing wheel, and manual intervention is usually required to assist in moving the lens, which is not only cumbersome, time-consuming and labor-intensive, but also easy to introduce human errors, reducing the consistency and stability of the production process.

[0004] In terms of the overall drive architecture of the equipment, the complexity of the multi-drive system makes the energy conversion efficiency of the equipment low. At the same time, due to the independent control of each drive system, the degree of automation of the equipment is limited, making it difficult to achieve full-process automated polishing production, requiring more manual monitoring and operation steps, which has become the key to restricting the improvement of production efficiency under large-scale production needs. In addition, the maintenance cost of traditional equipment is high, and multiple drive systems and complex transmission structures mean more failure points. Once a component fails, it is difficult to troubleshoot and repair, resulting in long equipment downtime, affecting the production continuity and economic benefits of the enterprise. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a single-stage driving device for polishing the periphery of an optical lens. The single-stage driving device for polishing the periphery of an optical lens comprises a bottom plate and a top plate, and the bottom plate and the top plate are fixed to each other via a vertical plate; a lens holding component for holding the lens is arranged between the bottom plate and the top plate, and the lens holding component comprises two upper and lower holding joint plates, and the holding ends of the two holding joint plates are arranged oppositely, and the lens holding component can drive the two holding joint plates to move closer to and away from each other; A lens driving component is provided for driving the upper holding joint plate to rotate, so as to drive the lens to rotate after the holding is completed, so as to polish the entire peripheral surface of the lens; A polishing operation component is arranged on the side of the lens holding component, and the polishing operation component includes a polishing grinding wheel. The polishing operation component can drive the polishing grinding wheel to rotate and drive the polishing grinding wheel to move in response to changes in the peripheral size of the lens.

[0009] Furthermore, a ratchet is fixed to the outer side surface of the first rotating rod, and a pawl plate that can cooperate with the ratchet is fixed to the bottom of the end of the first transverse shifting tooth plate away from the lens holding component. When the first transverse shifting spur gear rotates forward and drives the first transverse shifting tooth plate to move toward the lens holding component, the ratchet does not drive the pawl plate to move. When the first transverse shifting spur gear reverses, the ratchet drives the pawl plate to move to assist in resetting, so that the first transverse shifting tooth plate moves to engage with the first transverse shifting spur gear.

[0010] Furthermore, an anti-collision plate is fixed on the top of the chassis in front of the main connecting plate, and the anti-collision plate is slidably connected to the main connecting plate.

[0011] Furthermore, the lens driving component includes a first driving bevel gear fixed to the outer side surface of an upper driving rod, a second driving bevel gear that can mesh with the first driving bevel gear is arranged below the first driving bevel gear, and a long rod rotatably connected to the vertical plate is fixed to the side wall of the second driving bevel gear; both driving rods extend into the corresponding holding displacement plates, and a limiting wheel is fixed at one end of the driving rod in the holding displacement plate, and the driving rod and the limiting wheel are rotatably connected to the holding displacement plate; sprockets are fixed to the outer sides of the sub-rod and the long rod, and the two sprockets are connected by chains.

[0015] The beneficial effects of the present invention are as follows: 1. With a single servo motor as the core power source, it realizes highly coordinated operation of multiple functions such as lens holding, rotation, polishing wheel drive and displacement. During the entire polishing process, from the initial holding of the lens to the positioning of the polishing wheel, the stable rotation of the lens until the reset operation after polishing is completed, each action is connected and synchronized. For example, when the holding action is driven, the linkage of related components can quickly and stably fix the lens in a suitable position. At the same time, the polishing displacement components operate synchronously, so that the polishing wheel is accurately moved to the starting polishing position of the periphery of the lens, avoiding the time delay and position deviation caused by poor coordination in traditional equipment, and greatly improving the polishing efficiency and quality stability.

[0016] 2. With the exquisite coordination between wide spur gears, sliding spur gears, slide bars, square sliders, adaptable frames and compression springs, when the peripheral size of the lens changes, the polishing wheel can automatically adjust its position and contact pressure with the lens to ensure that it always maintains a good fit with the lens periphery during the entire polishing process. This adaptive ability not only reduces the tedious process of manual adjustment due to lens size differences and improves the degree of automation in production, but also effectively avoids problems such as uneven polishing caused by improper fit between the grinding wheel and the lens, significantly improving the polishing accuracy and surface quality of the lens.

[0017] 3. The use of a single-stage drive mode greatly improves energy utilization efficiency. Compared with the dispersed loss of energy in multiple drive units and complex transmission links in traditional multi-drive systems, the present invention concentrates the power supplied by the servo motor and efficiently transfers the energy to each functional component through a reasonable transmission structure, reducing unnecessary energy waste and reducing the long-term operating costs of the enterprise. At the same time, the overall structure of the equipment has been significantly simplified, reducing a large number of transmission components and independent drive units, which not only makes the equipment more compact and saves production space, but also reduces the risk of equipment failure and maintenance difficulty. Once a failure occurs, due to the relatively clear and simple structure, maintenance personnel can locate and repair the problem more quickly, shortening the downtime of the equipment, ensuring the continuity of production, and improving the production efficiency of the enterprise.

[0020] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention will be further described below in conjunction with the accompanying drawings: A single-stage drive device for polishing the outer periphery of an optical lens, such as Figure 1 and Figure 2As shown, it includes a bottom plate 1 and a top plate 2, which are fixed to each other via a vertical plate 3, and a plurality of protective shells 16 are installed on the top plate 2 and the vertical plate 3 to protect some components; a servo motor 8 is installed on the bottom plate 1, and a first rotating rod 9 is connected to the output end of the servo motor 8, and a second rotating rod 10 is connected to the top of the first rotating rod 9, and a main bevel gear 11 is fixed to the top of the second rotating rod 10, and a secondary bevel gear 12 is meshed on the main bevel gear 11, and a secondary rod 13 rotatably connected to the vertical plate 3 is fixed to the side wall of the secondary bevel gear 12.

[0023] The servo motor 8, as the core power input, can convert electrical energy into mechanical energy. Through a series of gears and rotating rods, the power can be transmitted to different directions and positions to drive multiple components. The protective shell 16 can effectively prevent dust, foreign matter, etc. from entering the interior of the device to damage the precision components, extend the service life of the device, and prevent operators from accidentally contacting the running parts and getting injured, thereby improving the safety and reliability of the equipment, ensuring the stable operation of the equipment, and laying the foundation for the subsequent lens polishing process.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a lens holding component for holding the lens is arranged between the bottom plate 1 and the top plate 2, and the lens holding component includes two upper and lower holding joint plates 41, and the holding ends of the two holding joint plates 41 are arranged oppositely, and the lens holding component can drive the two holding joint plates 41 to move closer to and away from each other; the lens holding component also includes two upper and lower first connecting rods 42, and two holding screw rods 43 are respectively fixed on the top and bottom of the two first connecting rods 42, and two second connecting rods 44 are respectively fixed on the top and bottom of the two holding screw rods 43. 44 are rotatably connected to the top plate 2 and the bottom plate 1 respectively, and two holding bevel gears 45 are fixed to the bottom and top of the upper and lower first connecting rods 42 respectively, and the side wall of one of the vertical plates 3 is rotatably connected to the side rod 46, and the outer side of the side rod 46 is fixed to the side bevel gear 47, and the side bevel gear 47 is meshed with the two holding bevel gears 45; the outer sides of the two holding screws 43 are connected to the holding displacement plates 48, and the holding displacement plates 48 are slidably connected to the vertical plate 3, and the upper and lower holding displacement plates 48 are respectively connected to the upper and lower holding joint plates 41 through two driving rods 49. Among them, the transmission chain formed by the first connecting rod 42, the holding screw 43, and the second connecting rod 44, in cooperation with the side rod 46 and the side bevel gear 47, effectively transmits and converts the power into the rotation of the holding screw 43, thereby driving the holding displacement plate 48 to slide on the vertical plate 3, and the holding joint plates 41 are moved closer or farther away from each other through the driving rod 49.

[0025] like Figure 2 and Figure 3As shown, in this embodiment, the lens holding component also includes a first transverse spur gear 410 fixed to the outer side of the first rotating rod 9, a second transverse spur gear 411 is fixed to the outer side of the second connecting rod 44 at the lower end, a main connecting plate 412 is slidably connected to the chassis 1, a first transverse tooth plate 413 that can mesh with the first transverse spur gear 410 is fixed to the main connecting plate 412, and a second transverse tooth plate 414 that can mesh with the second transverse spur gear 411 is also fixed to the main connecting plate 412, and an anti-collision plate 14 is fixed to the top of the chassis 1 in front of the main connecting plate 412, and the anti-collision plate 14 is slidably connected to the main connecting plate 412. Among them, when the first rotating rod 9 rotates, the first transverse spur gear 410 drives the first transverse tooth plate 413 to move, and then the main connecting plate 412 and the second transverse tooth plate 414 move as a whole, so as to realize the rotation control of the second connecting rod 44 and other components, and finally realize the opening and closing of the holding joint plate 41. The anti-collision plate 14 plays a protective role during the sliding process of the main connecting plate 412, preventing it from being damaged due to accidental collision, thereby ensuring the stability and safety of the equipment operation.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, after the gripping is completed, the first transverse gear plate 413 is disengaged from the first transverse spur gear 410. During the subsequent resetting (i.e., releasing the gripping process), even if the servo motor 8 is reversed, the first transverse spur gear 410 cannot drive the first transverse gear plate 413 to move. Therefore, the following components are provided. A ratchet 415 is also fixed to the outer side surface of the first rotating rod 9, and a pawl plate 416 that can cooperate with the ratchet 415 is fixed to the bottom of the end of the first transverse shifting tooth plate 413 away from the lens holding component. When the first transverse shifting spur gear 410 rotates forward and drives the first transverse shifting tooth plate 413 to move toward the lens holding component, the ratchet 415 does not drive the pawl plate 416 to move. When the first transverse shifting spur gear 410 reverses, the ratchet 415 drives the pawl plate 416 to move to assist in resetting, that is, the ratchet 415 drives the pawl plate 416 to move, and the first transverse shifting tooth plate 413 and the second transverse shifting tooth plate 414 move therewith, so that the first transverse shifting tooth plate 413 and the second transverse shifting tooth plate 414 move to mesh with the first transverse shifting gear and the second transverse shifting gear respectively, and the first transverse shifting tooth plate 413 and the second transverse shifting tooth plate 414 can drive the first transverse shifting gear and the second transverse shifting gear to reset.

[0027] On the basis of the above-mentioned embodiment 1, Figure 2 and Figure 3As shown, a lens driving component is provided for driving the upper holding joint plate 41 to rotate, so as to drive the lens to rotate after the holding is completed, so as to facilitate polishing of the entire outer peripheral surface of the lens; the lens driving component includes a first driving bevel gear 51 fixed to the outer side surface of the upper driving rod 49, and a second driving bevel gear 52 that can mesh with the first driving bevel gear 51 is provided below the first driving bevel gear 51, and a long rod 53 rotatably connected to the vertical plate 3 is fixed to the side wall of the second driving bevel gear 52; the two driving rods 49 both extend into the corresponding holding displacement plates 48, and a limiting wheel 54 is fixed at one end of the driving rod 49 in the holding displacement plate 48, and the driving rod 49 and the limiting wheel 54 are rotatably connected to the holding displacement plate 48; sprockets are fixed to the outer sides of the auxiliary rod 13 and the long rod 53, and the two sprockets are connected by a chain 55.

[0028] Among them, the meshing of the first driving bevel gear 51 and the second driving bevel gear 52, combined with the transmission of the sprocket chain 55 on the auxiliary rod 13 and the long rod 53, can effectively transmit power to the upper holding joint plate 41 after the lens is held stably, driving the lens to rotate at a uniform speed. The driving rod 49 extends into the holding displacement plate 48 and realizes stable rotation through the limit wheel 54, ensuring the stability and reliability of power transmission. In this way, the polishing grinding wheel 61 can evenly polish the outer peripheral surface of the lens during its rotation, avoiding problems such as uneven polishing, local over-polishing or insufficient polishing caused by unstable lens rotation, and improving the surface quality of the lens.

[0029] Based on the above embodiment 2, Figure 2 and Figure 4 As shown, a polishing operation component is arranged on the side of the lens holding component, and the polishing operation component includes a polishing grinding wheel 61. The polishing operation component can drive the polishing grinding wheel 61 to rotate and drive the polishing grinding wheel 61 to move to adapt to the change of the peripheral size of the lens; the polishing operation component also includes an adaptation frame 62 fixed to the end of the polishing wheel away from the lens holding component, and a square slideway 63 is provided inside the adaptation frame 62, and a square slider 64 is slidably connected in the slideway 63, and a slide rod 65 rotatably connected to the vertical plate 3 is fixed at one end of the square slider 64, and a mounting plate 66 is fixed to the outer side surface of the slide rod 65 close to the adaptation frame 62, and a compression spring 67 is fixed between the mounting plate 66 and the adaptation frame 62, and the compression spring 67 is sleeved on the outer side of the slide rod 65; a wide spur gear 68 is fixed to the outer side surface of the auxiliary rod 13, and a sliding spur gear 69 meshing with the wide spur gear 68 is fixed on the slide rod 65, and the width of the wide spur gear 68 is greater than that of the sliding spur gear 69.

[0030] Among them, the auxiliary rod 13 drives the wide spur gear 68 to rotate, and then drives the sliding spur gear 69 and the slide rod 65 to rotate, so that the polishing wheel 61 rotates to polish the lens. The adaptation frame 62, the square slider 64, the slide rod 65, the mounting plate 66 and the compression spring 67 cooperate to enable the polishing wheel 61 to automatically adjust its position according to the change of the peripheral size of the lens. When the size of the lens changes, the compression spring 67 can make the square slider 64 slide in the slideway 63 by telescoping, driving the polishing wheel 61 to move closer to or away from the lens, ensuring that the polishing wheel 61 always fits well with the periphery of the lens, and ensuring the consistency and stability of the polishing effect. This adaptive ability can reduce the time and energy required for frequent manual adjustments due to differences in lens size, and improve the versatility and production efficiency of the equipment.

[0031] Based on the above embodiment 3, Figure 2 As shown, a polishing displacement component is provided to drive the polishing grinding wheel 61 and its connecting components to move laterally as a whole, and to drive the polishing operating component to approach and move away from the polishing operating component when polishing starts and ends, respectively, to adapt to the holding and removal of the lens. A vertical moving screw 15 is fixed between the first rotating rod 9 and the second rotating rod 10, and the polishing displacement component includes a mirror-L-shaped vertical moving plate 71 connected to the outer side surface of the vertical moving screw 15, the vertical moving plate 71 is slidably connected to the outer wall of the vertical plate 3, the sliding rod 65 passes through the vertical plate 3 and is slidably connected to the vertical plate 3, the end of the sliding rod 65 away from the polishing grinding wheel 61 is rotatably connected to the transverse moving table 72, and the vertical plate 3 close to the transverse moving table 72 is rotatably connected to the transverse moving screw 73, the transverse moving screw 73 is connected to the transverse moving table 72, and the lower part of the transverse moving table 72 is slidably connected to a support frame 74 fixed to the vertical plate 3, and a vertical tooth plate 75 is fixed to the inner side wall of the upper end of the vertical moving plate 71, so the outer side surface of the transverse moving screw 73 is fixed with a vertical spur gear 76 that can mesh with the vertical tooth plate 75.

[0032] Among them, the vertical moving screw 15 between the first rotating rod 9 and the second rotating rod 10 rotates to drive the vertical moving plate 71 to move up and down, and through the meshing of the vertical moving tooth plate 75 and the vertical moving spur gear 76, the horizontal moving screw 73 is driven to rotate, and then the horizontal moving platform 72 drives the slide bar 65 and the polishing wheel 61 to move horizontally as a whole. At the beginning of polishing, the polishing wheel 61 is brought close to the lens for polishing; after polishing, the polishing wheel 61 is moved away from the lens to remove the lens. This precise displacement control ensures the orderly progress of the polishing process, and also makes the coordination between the various components of the equipment stronger, improves the automation and accuracy of the overall polishing process, and is conducive to improving production efficiency and product quality.

[0033] The working principle of the present invention is as follows: The lens to be polished is placed on a lower holding connector plate 41. When the device is started, the servo motor 8 installed on the chassis 1 starts to work. The servo motor 8 is the core power source of the entire device, and its output end drives the first rotating rod 9 to rotate. The rotation of the first rotating rod 9 transmits power to various components connected thereto, thereby driving a series of actions of the entire device to achieve functions such as lens holding, rotation, and corresponding movement of the polishing wheel 61.

[0034] Drive of holding action: when the servo motor 8 drives the first rotating rod 9 to rotate, it drives the first transverse spur gear 410 to rotate, and the first transverse spur gear 410 drives the first transverse gear plate 413 to slide, and then drives the first transverse gear plate 413, the main connecting plate 412 and the second transverse gear plate 414 to move as a whole toward the direction of the second transverse gear 411 (at this time, the ratchet 415 will not drive the ratchet plate 416 to move), and the second transverse gear plate 414 drives the second transverse gear 411 to rotate, so as to realize the rotation of the first connecting rod 42, the holding screw rod 43 and the second connecting rod 44 at the lower end, and through the cooperation of the two holding bevel gears 45 and the side bevel gear 47, the first connecting rod 42, the holding screw rod 43 and the second connecting rod 44 at the upper end are driven to rotate; during the rotation of the two holding screw rods 43, the two holding displacement plates 48 are driven to move in the direction of approaching each other, and the two holding joint plates 41 are driven to approach each other through the holding displacement plates 48 and the driving rod 49, so as to realize the holding of the lens.

[0035] Polishing displacement component drive: The polishing displacement component operates synchronously with the holding action. The servo motor 8 drives the first rotating rod 9 and the vertical moving screw 15 to rotate, thereby driving the vertical moving plate 71 to move upward, so that the vertical moving gear plate 75 gradually engages with the vertical moving spur gear 76, and then drives the vertical moving spur gear 76 and the transverse moving screw 73 to rotate. During the rotation of the transverse moving screw 73, the transverse moving platform 72 connected thereto is driven to move toward the direction close to the lens holding component, thereby pushing the sliding rod 65 and the polishing grinding wheel 61 as a whole to move toward the middle of the two holding joint plates 41.

[0036] 1 and 1 , and the second bevel gear 52 is rotated together with the first bevel gear 52. The first bevel gear 51 is rotated with the second bevel gear 52, and the second bevel gear 52 is rotated together with the first bevel gear 52. The first bevel gear 51 is rotated with the second bevel gear 52, and the first bevel gear 51 is rotated with the second ... first bevel gear 51. The first bevel gear 51 is rotated with the second bevel gear 52, and the first bevel gear 51 is rotated with the first bevel gear 51. The first bevel gear 51 is rotated with the second bevel gear 52, and the first bevel gear 51 is rotated with the first bevel gear 51. The first bevel gear 51 is rotated with the second bevel gear 52, and the first bevel gear 51 is rotated with the first bevel gear 51. The first

[0037] Polishing operation component drive: During the operation of the servo motor 8, the auxiliary rod 13 rotates and drives the wide spur gear 68 to rotate, and then drives the sliding spur gear 69 meshing with it to rotate (since the width of the wide spur gear 68 is wider than the sliding spur gear 69, even when the polishing displacement component is operating, the sliding spur gear 69 will not disengage from the wide spur gear 68), and the slide bar 65 rotates therewith. Since the square slider 64 adapts to the frame 62, the square slider 64, the adaptation frame 62 and the polishing wheel 61 will rotate as a whole with the slide bar 65. During the rotation of the polishing wheel 61, the outer peripheral surface of the lens is polished. As the outer diameter of the outer peripheral surface of the lens changes, through the compression and rebound of the compression spring 67, the square slider 64 can slide in the slideway 63 to ensure that the polishing wheel 61 can always fit well with the outer periphery of the lens, thereby ensuring the polishing effect.

[0038] Reset action drive: When the lens needs to be reset and taken out after polishing is completed, since the first transverse gear plate 413 is out of mesh with the first transverse spur gear 410 after the gripping is completed, in the subsequent resetting process, if the servo motor 8 is reversed, the first transverse spur gear 410 alone cannot drive the first transverse gear plate 413 to move. At this time, the ratchet 415 fixed on the outer side of the first rotating rod 9 and the ratchet plate 416 fixed at the bottom of the end of the first transverse gear plate 413 away from the lens gripping part and capable of cooperating with the ratchet 415 come into play. When the first transverse shift spur gear 410 rotates forward and drives the first transverse shift tooth plate 413 to move toward the lens holding component, the ratchet 415 does not drive the pawl plate 416 to move; when the first transverse shift spur gear 410 reverses, the ratchet 415 drives the pawl plate 416 to move for auxiliary resetting, that is, the ratchet 415 drives the pawl plate 416 to move, and the first transverse shift tooth plate 413 and the second transverse shift tooth plate 414 move therewith, so that the first transverse shift tooth plate 413 and the second transverse shift tooth plate 414 move to engage with the first transverse shift spur gear 410 and the second transverse shift tooth plate 411 respectively, so that the first transverse shift tooth plate 413 and the second transverse shift tooth plate 414 drive the first transverse shift spur gear 410 and the second transverse shift gear 411 to reset, preparing for the next holding action, and the rotation of the vertical shift screw 15 drives the vertical shift plate 71 to move downward and reset, thereby driving the polishing grinding wheel 61 as a whole to gradually move away from the lens, so as to facilitate the removal of the lens.
