As an advanced polishing technology, the multi-dimensional six-axis robot polishing device has the advantages of high precision, high efficiency, and strong flexibility. It can meet the needs of modern lens mold manufacturing. In the future, with the continuous advancement of robot technology, control technology, and sensor technology, the multi-dimensional six-axis robot polishing device will be more widely used in the field of lens mold manufacturing, promoting the high-quality development of the optical industry.

[0003] At present, the debris generated by polishing cannot be quickly cleaned during the processing of the mold, which not only causes pollution to the processing environment, but also affects the normal operation of the equipment. In addition, during the positioning of the lens mold, a vacuum adsorption platform is used to fix the mold with a flat and smooth surface or a large mold, while a gluing method is often used to fix the smaller mold. In addition, for molds with irregular shapes, multiple fixing fixtures may even be required to be used in combination, making mold fixation inconvenient.

[0004] Therefore, a multi-dimensional six-axis robot lens mold polishing process was designed to optimize the above problems. Summary of the invention

A vacuum adsorption mechanism is provided at the middle position of the top of the carrier plate, and side clamping mechanisms are provided on both sides of the carrier plate, so that two methods can be used for positioning during the fixing of the mold, which not only improves the stability of the installation, but also has stronger applicability. In addition, the side clamping mechanism composed of a strip groove, a slider, a second spring, a sliding rod, a clamping plate, and a third spring, in conjunction with a vacuum pump, a vacuum bin, a slide groove, a mounting block, an arc groove, a spherical block, an air suction port, a valve core, an adjustment groove, The vacuum adsorption mechanism composed of a hose, a vertical rod, a sealing ring, a first spring, a cylinder body, and a first piston can control the vertical movement of the mounting block according to the different shapes of the mold during the process of clamping the mold side, and the spherical block can rotate inside the arc groove. It can automatically fit on the surface of an irregular workpiece during the rising process, and then fix it by vacuum adsorption, which increases the contact area with the workpiece and improves the fixing effect.

[0038] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0039] like Figure 1-Figure 8As shown, the present embodiment provides a multi-dimensional six-axis robot lens mold polishing process, comprising a six-axis robot body 1, a polishing motor 101 installed at the end of the six-axis robot body 1, a polishing head 102 installed at the output end of the polishing motor 101, and a processing table 2 for supporting the mold, a carrier plate 3 is arranged parallel to the top of the processing table 2, a dust suction mechanism 8 is arranged vertically slidingly inside the processing table 2 and located on the side of the carrier plate 3, a lifting mechanism 6 for controlling the up and down movement of the dust suction mechanism 8 is arranged at the bottom of the carrier plate 3, the carrier plate 3 and the dust suction mechanism 8 move in opposite directions, a vacuum adsorption mechanism 4 is arranged at the middle position of the top of the carrier plate 3, side clamping mechanisms 5 are arranged at both ends of the top of the carrier plate 3, and a spacing adjustment mechanism 7 for controlling the movement of the side clamping mechanism 5 is arranged below the carrier plate 3, and a locking mechanism 9 for positioning the horizontal height of the carrier plate 3 is arranged on the processing table 2.

[0040] The overall working principle is as follows: when processing the mold, the carrier 3 is initially higher than the processing table 2. The mold is placed in the middle position of the top of the carrier 3, and then the mold is pressed down together with the carrier 3. While the mold is pressed down, the lifting mechanism 6 is used to control the dust suction mechanism 8 to rise from the inside of the processing table 2. After the dust suction port 802 on the dust suction mechanism 8 is at the same height as the mold, the control of the downward movement of the carrier 3 and the mold is stopped. During the downward movement of the mold, a linkage control method is adopted, and the side clamping mechanism 5 is used to clamp and limit the two sides of the mold. Then, the vacuum adsorption mechanism 4 is used to perform negative pressure suction on the bottom of the mold for adsorption positioning. In the process of adsorption positioning, the locking mechanism 9 is used to limit the position of each component on the processing table 2 to ensure that the position of the mold on the carrier 3 is fixed.

[0041] In this embodiment, the dust suction mechanism 8 includes a box body 801, a dust suction port 802, a dust collecting bin 803, a filter 804 and a negative pressure fan 805. The box body 801 is vertically slidably set on the processing table 2. The top of the box body 801 close to the carrier plate 3 is provided with a dust suction port 802 along the length direction. The interior of the box body 801 is provided with a dust collecting bin 803 connected to the dust suction port 802. A filter 804 is installed on the inner top of the dust collecting bin 803. A negative pressure fan 805 is installed on the side of the box body 801 away from the carrier plate 3, and the input end of the negative pressure fan 805 is connected to the interior of the dust collecting bin 803.

[0042] Local working principle: During the polishing process, the negative pressure fan 805 is started to generate negative pressure inside the dust collecting bin 803, and the gas containing metal dust enters the dust collecting bin 803 through the dust suction port 802 and is filtered by the filter 804, and the metal dust is intercepted at the top of the filter 804.

[0043] In this embodiment, the lifting mechanism 6 includes a screw 607, an inner screw tube 608 and a rotating assembly. The screw 607 is vertically rotatably installed at both ends inside the processing table 2. The outer side of the screw 607 is threadedly installed with an inner screw tube 608. The sides of the inner screw tube 608 are fixed on the box body 801. A rotating assembly for controlling the rotation of the screw 607 is provided at the bottom of the carrier plate 3.

[0044] Partial working principle: When the carrier plate 3 moves downward, the screw rod 607 is automatically driven to rotate through the rotating assembly. The rotation of the screw rod 607 drives the inner screw tube 608 to move along the length direction of the screw rod 607, thereby controlling the rise of the box body 801.

[0045] In this embodiment, the rotating assembly includes a vertical rod 601, a fifth spring 602, a rack 603, a gear 604, a worm 605 and a worm wheel 606. The vertical rod 601 is vertically fixed at both ends of the carrier plate 3. The vertical rod 601 is vertically slidably connected to the processing table 2. A fifth spring 602 is provided between the bottom of the carrier plate 3 and the top of the processing table 2. The vertical rod 601 passes through the inside of the fifth spring 602. Racks 603 are vertically installed at both ends of the bottom of the carrier plate 3. Gears 604 are rotatably installed at both ends of the inside of the processing table 2. The rack 603 is meshed with the gear 604. A worm 605 is installed on the side of the rack 603. A worm wheel 606 meshed with the worm 605 is fixed to the top of the screw 607.

[0046] Local working principle: during the downward movement of the carrier plate 3, the fifth spring 602 will be compressed and the downward movement of the rack 603 will be controlled. The downward movement of the rack 603 will control the rotation of the gear 604. The gear 604 drives the worm 605 to rotate. The worm 605 drives the worm wheel 606 at the top of the screw 607 to rotate, thereby controlling the rotation of the screw 607. When the processing is completed and the locking state of the carrier plate 3 is released, the carrier plate 3 will move up and reset under the resetting action of the fifth spring 602, and the box body 801 will automatically move down to the inside of the processing table 2.

[0047] In this embodiment, the side clamping mechanism 5 includes a strip groove 501, a slider 502, a second spring 503, a sliding rod 504, a clamping plate 505 and a third spring 506. The strip groove 501 is opened at the middle position of the carrier plate 3 along the length direction of the carrier plate 3. Sliders 502 are slidably installed at both ends of the strip groove 501. Second springs 503 are provided between the slider 502 and the end of the strip groove 501. Sliding rods 504 are slidably installed inside the slider 502 along the length direction of the carrier plate 3. Clamping plates 505 are fixed at the facing ends of the two groups of sliding rods 504. A third spring 506 is provided between the clamping plate 505 and the slider 502.

[0048] Local working principle: In the initial state, the sliders 502 are located at both ends of the strip groove 501. During the downward movement of the carrier plate 3, the two groups of sliders 502 will be controlled by the spacing adjustment mechanism 7 to move toward each other. The splint 505 will first fit with the side of the mold and compress the third spring 506. The elastic force of the third spring 506 can ensure that the splint 505 fits the side of the mold.

[0049] In this embodiment, the spacing adjustment mechanism 7 includes a wire reel 701, a pull rope 702 and a fixed pulley 703. The wire reel 701 is installed on the side of the gear 604. The pull rope 702 is wound around the wire reel 701. The fixed pulley 703 is symmetrically installed inside the strip groove 501. The top of the pull rope 702 passes through the top of the fixed pulley 703 and is fixedly connected to the side of the slider 502.

[0050] Partial working principle: When the carrier plate 3 moves downward to control the rotation of the gear 604, the gear 604 will control the rotation of the wire roll 701 during the rotation, the pull rope 702 will be wound around the wire roll 701, and the top of the pull rope 702 will pull the slider 502 toward the mold, automatically controlling the splint 505 to fit the side of the mold.

[0051] In this embodiment, the vacuum adsorption mechanism 4 includes a vacuum pump 401, a vacuum chamber 402, a slide 403, a mounting block 404, an arc groove 405, a spherical block 406, an air inlet 407, a valve core 408, an adjustment groove 409, a hose 4010, a vertical pipe 4011 and a sliding assembly. The vacuum pump 401 is installed inside the processing table 2. The vacuum pump 401 is opened at the middle position of the bottom of the carrier plate 3. The slide grooves 403 are evenly arranged in a rectangular array at the middle position of the top of the carrier plate 3. The interior of the slide grooves 403 is vertically slidably provided with mounting blocks 404, and the bottom ends of the mounting blocks 404 are fixed with extensions to A vertical pipe 4011 is provided inside the vacuum chamber 402, and the vertical pipe 4011 is slidably connected to the carrier plate 3. An arc groove 405 is provided on the top of the mounting block 404. A spherical block 406 is rotatably installed inside the arc groove 405, and the top of the spherical block 406 is flat. An air intake port 407 is provided on the top of the spherical block 406, and a valve core 408 is provided inside the air intake port 407. An adjusting groove 409 is provided at the bottom of the arc groove 405. A hose 4010 is provided between the bottom end of the air intake port 407 and the vertical pipe 4011, and a sliding component for controlling the up and down movement of the mounting block 404 is provided at the bottom of the slide groove 403.

[0052] Local working principle: When the mold is clamped and limited from the side by the clamping plate 505, the sliding component will control the mounting block 404 to slide inside the slide groove 403, and the mounting block 404 will drive the spherical block 406 to move upward. Since the spherical block 406 can rotate inside the arc groove 405, during the upward movement, the suction port 407 on the top spherical block 406 can fit tightly with the surface of the mold. When all the suction ports 407 below the mold are in contact with the mold, start the vacuum pump 401 to extract the air inside the vacuum chamber 402. Due to the action of the valve core 408, the suction port 407 that is not in contact with the mold is in a sealed state, and the suction port 407 at the contact with the mold generates suction to the mold, thereby adsorbing and fixing the mold. The valve core 408 is a part inside the vacuum adsorption platform in the prior art, which belongs to the prior art and will not be described in detail in this application.

[0053] In this embodiment, a rubber gasket is provided at the inner bottom of the arc groove 405 and outside the adjustment groove 409 , and the inner side of the rubber gasket is in contact with the surface of the spherical block 406 .

[0054] Partial working principle: The use of the rubber gasket increases the friction resistance between the spherical block 406 and the arc groove 405, which can facilitate the adjustment and limitation of the position of the spherical block 406 after use.

[0055] In this embodiment, the sliding assembly includes a sealing ring 4012, a first spring 4013, a cylinder body 4014 and a first piston 4015. The multiple groups of slide grooves 403 are connected to each other. The sealing ring 4012 is fixed to the bottom of the outer side of the mounting block 404, and the outer side of the sealing ring 4012 is in contact with the inner wall of the slide groove 403. The first spring 4013 is fixedly connected between the bottom of the mounting block 404 and the inner bottom of the slide groove 403. The cylinder body 4014 is fixed on the side of the slider 502 away from the clamping plate 505. A conduit is provided between the cylinder body 4014 and the slide groove 403. The end of the sliding rod 504 extends to the inside of the cylinder body 4014. The first piston 4015 is fixed to the end of the sliding rod 504. The first piston 4015 slides inside the cylinder body 4014.

[0056] Local working principle: in the process of using the side clamping mechanism 5 to squeeze the side of the mold, the slider 502 will move a certain distance after the clamping plate 505 is fitted with the mold, so the slide rod 504 will slide on the slide rod 502. The sliding of the slide rod 504 will drive the first piston 4015 inside the cylinder body 4014 to slide, and inject the gas inside the cylinder body 4014 into the interior of the slide groove 403. At the same time, the upward sliding of the mounting block 404 is controlled. The linkage control method is adopted, and the lifting and lowering control of the mounting block 404 is more convenient.

[0057] In this embodiment, the locking mechanism 9 includes a sleeve 901, a second piston 902, an extrusion rod 903, a sealing plug 904, a fourth spring 905 and a through hole 906. The sleeve 901 is fixed at both ends of the top of the processing table 2. The openings of the sleeve 901 are all facing the rack 603. The second piston 902 is slidably arranged inside the sleeve 901. The extrusion rod 903 is fixed to the side of the second piston 902 close to the opening. A sealing plug 904 is fixed to the opening inside the sleeve 901. The extrusion rod 903 passes through the inside of the sealing plug 904. A fourth spring 905 is arranged between the second piston 902 and the inner end of the sleeve 901. A through hole 906 is opened at the end of the sleeve 901. The end of the top of the sleeve 901 close to the sealing plug 904 is connected to the inside of the vacuum chamber 402 through a conduit.

[0058] Local working principle: When the vacuum pump 401 is started and the interior of the vacuum chamber 402 is in a negative pressure state, the vacuum chamber 402 is connected to the interior of the sleeve 901, and the open end of the sleeve 901 is in a sealed state due to the sealing plug 904, while the end of the sleeve 901 is in an open state due to the existence of the through hole 906. Therefore, the second piston 902 will be controlled to drive the extrusion rod 903 to slide inside the sleeve 901.
