Description

Technical Field

[0001] This invention belongs to the field of grinding and polishing technology, and particularly relates to a grinding and polishing robot for multi-layer lenses. Background Technology

[0002] Grinding machines use high-speed rotating grinding heads to remove excess material from workpiece surfaces, performing grinding, polishing, and finishing functions. Currently, multi-layered lenses require grinding and polishing operations during processing. In existing technology, when grinding optical lenses, a cylinder drives a piston rod to push a motor downwards. The motor, through a rotating shaft, causes the grinding disc to rotate at high speed, grinding the optical lens below. During processing, a water pump draws water from the cooling tank via a suction pipe and sprays it out through a spray pipe to cool and reduce dust on the optical lens. However, existing multi-layered lenses are composed of different materials (such as resin, glass, and polycarbonate), each requiring a specific grinding head to avoid material damage. Current technology cannot quickly change grinding heads according to the material of the multi-layered lens, resulting in slow processing efficiency. Furthermore, different materials require matching coolants to prevent damage, but current technology cannot switch the appropriate coolant when changing grinding heads, further impacting processing efficiency.

[0008] Preferably, the liquid storage mechanism further includes a first pipe connected to the top of the liquid storage tank, and a first control valve is installed on the first pipe.

[0009] Preferably, the cooling mechanism includes a drive pump fixedly installed on the outer wall of the sealing shell, one side of the drive pump is connected to the sealing shell through a third pipe, and the other side of the drive pump is connected to a nozzle through a fourth pipe. A liquid container is provided on the outer side of the grinding table, and a fifth pipe is connected to the bottom of the liquid container. A second control valve is installed on the fifth pipe.

[0010] Preferably, the switching mechanism further includes a rack fixedly connected to the top of the first mounting plate and the second mounting plate. A spur gear is meshed on the outer side of the rack. A drive shaft is fixedly connected inside the spur gear. A support base is fixedly connected inside the drive box. The drive shaft is rotatably connected to the support base. A first bevel gear is fixedly connected to the outer side of the drive shaft. A second bevel gear is provided on the outer side of the first bevel gear. A lead screw is fixedly connected to the inner side of the second bevel gear. A support frame is fixedly connected to the top of the drive box. The lead screw is rotatably connected to the support frame. A lead screw nut is provided on the outer side of the lead screw. A connecting plate is provided on the outer side of the lead screw nut. The connecting plate is slidably connected to the support frame. A sealing cover is fixedly connected to one end of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when grinding multi-layered lens workpieces, the workpiece is first placed in the center of the grinding table. Then, the first electric cylinder inside the protective housing is activated. The output of the first electric cylinder drives the first sliding plate in the first guide groove. Because a clamping plate is fixedly connected to the top of the first sliding plate, multiple clamping plates move towards the multi-layered lens workpiece and clamp it in multiple directions, fixing it in place. After the multi-layered lens workpiece is clamped and fixed, the robotic arm drives the grinder below the switching mechanism to move around the workpiece. The output of the drive motor drives the grinding head to rotate, while the multi-layered lens workpiece is clamped and fixed, allowing the grinding head to stably grind the workpiece. This invention can stably grind multi-layered lens workpieces, thereby improving the grinding effect.

[0012] When switching between different types of grinders is required during the grinding of multi-layered lens workpieces, this invention first activates the third electric cylinder fixedly mounted on the bottom of the first mounting plate. The output of the third electric cylinder drives the currently operating grinder upward and retracts it into the tool holder. Then, the second electric cylinder is activated, and its output drives the second sliding plate at the bottom of the first mounting plate to slide within the second guide groove. The first mounting plate, located in the middle of the tool holder, is pulled to the edge of the tool holder, causing the currently operating grinder to reset within the tool holder. Next, the corresponding fourth electric cylinder is activated, and its output drives the second sliding plate at the bottom of the second mounting plate to slide within the second guide groove. The second mounting plate, located at the edge of the tool holder, is pushed to the middle of the tool holder. Finally, the fifth electric cylinder fixedly mounted on the bottom of the second mounting plate is activated, and its output pushes the grinder to be switched out of the tool holder. This invention enables rapid switching between different types of grinders, facilitating the use of specific grinders based on the hardness requirements of different materials in multi-layered lens workpieces.

[0013] Before grinding multi-layered lens workpieces, this invention allows the opening of a first control valve to deliver the corresponding external coolant to the storage tank via a first pipe. During grinding, the coolant in the storage tank is delivered to a sealed housing via a second pipe. A drive pump fixed to the outer wall of the sealed housing is then activated, causing the coolant inside the sealed housing to be delivered to a fourth pipe via a third pipe. Because the nozzle corresponds to the grinding head, the coolant in the fourth pipe can be sprayed onto the grinding head through the nozzle. This invention sprays coolant during the grinding process, reducing frictional resistance and temperature, thereby improving the grinding effect. After the coolant is sprayed onto the grinding head, it flows through the grinding table into a collection hopper. Opening the second control valve allows the coolant in the collection hopper to be discharged through a fifth pipe, achieving coolant collection. In this invention, during the switching of the grinder, the output end of the second electric cylinder first drives the first mounting plate to retract from the middle of the tool holder to its reset position at the edge. This causes the rack fixedly connected to the top of the first mounting plate to move towards the edge of the tool holder. During this movement, the rack drives the spur gear to rotate, which in turn drives the transmission shaft to rotate inside the support. Because a first bevel gear is fixedly connected to the outside of the transmission shaft, and the first bevel gear meshes with a second bevel gear, it can drive the second bevel gear and the transmission screw fixedly connected to its inner side to rotate. Subsequently, under the action of the screw nut, the connecting plate moves downward. Because a sealing cover is fixedly connected to the bottom of the connecting plate, the sealing cover can move downward and block the second pipe at the lower end of the corresponding liquid tank. When the output end of the fourth electric cylinder pushes the second mounting plate from the edge of the tool holder to the middle position, the rack fixedly connected to the top of the second mounting plate moves towards the middle of the tool holder, which in turn drives the sealing cover downward and opens the second pipe at the lower end of the corresponding liquid tank. This invention allows for switching between different types of coolant while changing the grinder, making it convenient to use the appropriate coolant based on the different material requirements of multi-layered lens workpieces.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] The following electrical components are all electrically connected to the external PLC controller.

[0018] Reference Figure 1 - Figure 7A multi-layer lens polishing robot includes a frame 1, a polishing table 2 on the top of the frame 1, a multi-layer lens workpiece 3 in the middle of the polishing table 2, a fixing mechanism 4 on the outside of the multi-layer lens workpiece 3, a robotic arm 5 on the frame 1, and a liquid storage mechanism 9 connected to one end of the robotic arm 5. The liquid storage mechanism 9 includes a sealing shell 905, a liquid storage tank 901, and a second pipe 904. The liquid storage tank 901 is located inside the sealing shell (905), and the second pipe 904 is located on the side wall of the liquid storage tank (901). A drive box 8 is located at the bottom of the liquid storage mechanism 9, a switching mechanism 7 is located below the drive box 8, and a polisher 6 is located below the switching mechanism 7. The polisher 6 includes a mounting shell 601, a drive motor 602, and a polishing head 603. The drive motor 602 is located inside the mounting shell (601), and the drive motor 602 drives the polishing head (603). A cooling mechanism 10 is located on the outside of the polisher 6.

[0019] In the embodiments, reference is made to Figures 1-3 To ensure stable grinding of multi-layered lens workpiece 3, the present invention includes a fixing mechanism 4 comprising a protective shell 401 fixedly installed inside the grinding table 2. A first electric cylinder 402 is fixedly installed inside the protective shell 401. A first sliding plate 403 is fixedly connected to the output end of the first electric cylinder 402. A clamping plate 405 is fixedly connected to the top of the first sliding plate 403, and a baffle 406 is fixedly connected to the outer wall of the clamping plate 405. The fixing mechanism 4 also includes a first guide groove 404 formed inside the grinding table 2, and the first sliding plate 403 is slidably connected to the first guide groove 404.

[0020] Specifically, when polishing the multi-layer lens workpiece 3, the multi-layer lens workpiece 3 is first placed in the middle of the polishing table 2, and then the first electric cylinder 402 inside the protective shell 401 is activated. The output end of the first electric cylinder 402 will drive the first sliding plate 403 in the first guide groove 404. Because the top of the first sliding plate 403 is fixedly connected to the clamping plate 405, multiple clamping plates 405 will move towards the multi-layer lens workpiece 3 and clamp and fix the multi-layer lens workpiece 3 in multiple directions.

[0021] In this invention, after the multi-layer lens workpiece 3 is clamped and fixed, the robotic arm 5 drives the polisher 6 below the switching mechanism 7 to move around the multi-layer lens workpiece 3. The output end of the drive motor 602 can drive the polishing head 603 to rotate, while the multi-layer lens workpiece 3 is clamped and fixed, allowing the polishing head 603 to stably polish the multi-layer lens workpiece 3. This invention can stably polish the multi-layer lens workpiece 3, thereby improving the polishing effect of the multi-layer lens workpiece 3.

[0022] In the embodiments, reference is made to Figure 4To enable rapid switching between different types of grinders 6, the present invention includes a switching mechanism 7 comprising a tool holder 701 fixedly connected to the bottom of a drive housing 8; a second electric cylinder 702 fixedly installed inside the drive housing 8; a first mounting plate 703 fixedly connected to the output end of the second electric cylinder 702; a third electric cylinder 704 fixedly installed at the bottom of the first mounting plate 703; a set of grinders 6 connected to the output end of the third electric cylinder 704; a fourth electric cylinder 705 fixedly installed inside the drive housing 8; a second mounting plate 706 fixedly connected to the output end of the fourth electric cylinder 705; a fifth electric cylinder 707 fixedly connected to the bottom of the second mounting plate 706; and another set of grinders 6 connected to the output end of the fifth electric cylinder 707. The switching mechanism 7 also includes a second sliding plate 708 fixedly connected to the bottom of the first mounting plate 703 and the second mounting plate 706; a second guide groove 709 is provided on the inner side of the drive housing 8; and the second sliding plate 708 is slidably connected to the second guide groove 709.

[0023] Specifically, when it is necessary to switch between different types of grinders 6 during the grinding of multi-layer lens workpiece 3, the third electric cylinder 704 fixedly mounted on the bottom of the first mounting plate 703 is first activated. The output end of the third electric cylinder 704 will drive the working grinder 6 to move upward and retract into the tool holder 701. Then, the second electric cylinder 702 is activated. The output end of the second electric cylinder 702 will drive the second sliding plate 708 at the bottom of the first mounting plate 703 to slide inside the second guide groove 709. The first mounting plate 703 located in the middle of the tool holder 701 is pulled to the edge of the tool holder 701, so that the working grinder 6 is reset in the tool holder 701. Next, the corresponding fourth electric cylinder 705 is activated. The output end of the fourth electric cylinder 705 drives the second sliding plate 708 at the bottom of the second mounting plate 706 to slide inside the second guide groove 709. The second mounting plate 706, located at the edge of the tool holder 701, is pushed to the middle of the tool holder 701. Then, the fifth electric cylinder 707, which is fixedly installed at the bottom of the second mounting plate 706, is activated. The output end of the fifth electric cylinder 707 drives the grinder 6 to be switched out from inside the tool holder 701. This invention can quickly switch between different types of grinders 6, making it convenient to use a specific grinder 6 according to the hardness requirements of different materials of the multi-layer lens workpiece 3.

[0024] In the embodiments, reference is made to Figure 2 , Figures 5-6In order to spray coolant during the polishing of multi-layer lens workpiece 3, the present invention includes a first pipe 902 connected to the top of the storage tank 901, and a first control valve 903 installed on the first pipe 902. The cooling mechanism 10 includes a drive pump 1002 fixedly installed on the outer wall of the sealing shell 905. One side of the drive pump 1002 is connected to the sealing shell 905 through a third pipe 1001, and the other side of the drive pump 1002 is connected to a nozzle 1004 through a fourth pipe 1003. A liquid container 1005 is provided on the outer side of the polishing table 2, and a fifth pipe 1006 is connected to the bottom of the liquid container 1005. A second control valve 1007 is installed on the fifth pipe 1006.

[0025] Specifically, before polishing the multi-layer lens workpiece 3, the present invention can open the first control valve 903 and transport the corresponding external coolant to the storage tank 901 through the first pipe 902.

[0026] In this invention, when polishing a multi-layered lens workpiece 3, the coolant inside the reservoir 901 is transported to the sealed housing 905 through the second pipe 904. Then, the drive pump 1002, fixedly installed on the outer wall of the sealed housing 905, is activated, causing the coolant inside the sealed housing 905 to be transported to the fourth pipe 1003 through the third pipe 1001. Because the nozzle 1004 corresponds to the polishing head 603, the coolant inside the fourth pipe 1003 can be sprayed onto the polishing head 603 through the nozzle 1004. This invention can spray coolant during the polishing process of the multi-layered lens workpiece 3, reducing frictional resistance and temperature during polishing, thereby improving the polishing effect of the multi-layered lens workpiece 3.

[0027] In this invention, after the coolant is sprayed onto the grinding head 603, the coolant will flow into the liquid collection hopper 1005 through the grinding table 2. Opening the second control valve 1007 can discharge the coolant in the liquid collection hopper 1005 through the fifth pipe 1006, thereby collecting the coolant.

[0028] In the embodiments, reference is made to Figures 4-5 , Figure 7To allow for switching between different types of coolant while switching the grinder 6, the present invention includes a switching mechanism 7 that further comprises a rack 710 fixedly connected to the top of the first mounting plate 703 and the second mounting plate 706. A spur gear 711 is meshed on the outer side of the rack 710. A drive shaft 712 is fixedly connected inside the spur gear 711. A support base 713 is fixedly connected inside the drive housing 8. The drive shaft 712 is rotatably connected to the support base 713. A first bevel gear 71 is fixedly connected to the outer side of the drive shaft 712. 4. A second bevel gear 715 is provided on the outer side of the first bevel gear 714. A transmission screw 716 is fixedly connected to the inner side of the second bevel gear 715. A support frame 717 is fixedly connected to the top of the drive box 8. The transmission screw 716 is rotatably connected to the support frame 717. A screw nut 718 is provided on the outer side of the transmission screw 716. A connecting plate 719 is provided on the outer side of the screw nut 718. The connecting plate 719 is slidably connected to the support frame 717. A sealing cover 720 is fixedly connected to one end of the connecting plate 719.

[0029] Specifically, during the switching of the grinder 6, the output end of the second electric cylinder 702 first drives the first mounting plate 703 to retract from the middle of the tool holder 701 to the edge of the tool holder 701, causing the rack 710 fixedly connected to the top of the first mounting plate 703 to move towards the edge of the tool holder 701 along with the first mounting plate 703. During the movement, the rack 710 drives the spur gear 711 to rotate, which in turn drives the transmission shaft 712 to rotate inside the support base 713. Because the outer side of the transmission shaft 712 is fixedly connected to the first bevel gear 714, and the first bevel gear 714 meshes with the second bevel gear 715, it can drive the second bevel gear 715 and the transmission screw 716 fixedly connected to the inner side of the second bevel gear 715 to rotate. Subsequently, under the action of the screw nut 718, the connecting plate 719 will move downward. Because the bottom of the connecting plate 719 is fixedly connected to the sealing cover 720, the sealing cover 720 can move downward and block the second pipe 904 at the lower end of the corresponding liquid storage tank 901.

[0030] When the output end of the fourth electric cylinder 705 drives the second mounting plate 706 from the edge of the tool holder 701 to the middle position, the rack 710 fixedly connected to the top of the second mounting plate 706 will move towards the middle of the tool holder 701 along with the second mounting plate 706, thereby driving the sealing cover 720 to move downward and opening the second pipe 904 at the lower end of the corresponding liquid storage tank 901. This invention allows for switching between different types of coolant while switching the grinder 6, facilitating the use of matching coolant according to the different material requirements of the multi-layer lens workpiece 3. The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of this invention.
