Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-9, an embodiment of the present invention is: a high-precision optical lens processing device includes a processing table 1, a mounting seat 2 is fixed on the upper surface of the processing table 1, a motor 3 is fixed on the inner wall of the mounting seat 2, a processing chamber 4 is fixed on the upper surface of the processing table 1, the processing table 1 is provided with a calibration device 5 for facilitating the central positioning of the lens, and also includes an impurity removal device 6 and a limiting device 7 for facilitating polishing. Among them, the calibration device 5 includes a fixed seat 51, a limiting block 52, a rotating disk 53, a handle 54, a push rod 55, a guide groove 56, a positioning rod 57, a first thread groove 58, a convex block 59, a connecting rod 510, a suction cup 511, a first gear 512, a sealing block 513, a guide rod 514, a limiting rod 515 and a second thread groove 516. The fixed seat 51 is fixedly connected to the upper surface of the processing table 1, the limiting block 52 is fixedly connected to the upper surface of the processing table 1, the inner wall of the limiting block 52 is rotatably connected with a rotating disk 53, the outer wall of the rotating disk 53 is fixed with a handle 54. When the handle 54 is rotated, the handle 54 will drive the closely connected rotating disk 53 to rotate around a specific axis. A push rod 55 passes through the fixed seat 51 and the limiting block 52, and the through part is slidably connected. A guide groove 56 is opened on the front surface of the rotating disk 53, and a positioning rod 57 passes through the guide groove 56, and the through part is slidably connected. During the process of the rotating disk 53 starting to rotate, since one end of the positioning rod 57 is restricted in the pre-designed guide groove 56, it will slide along the path defined by the guide groove 56. A first thread groove 58 is opened on the outer wall of the push rod 55, a convex block 59 is fixed on the inner wall of the rotating disk 53, and the outer wall of the convex block 59 fits the inner wall of the first thread groove 58. As a key component on the rotating disk 53, the convex block 59 will slide along the adapted first thread groove 58, so that the convex block 59 can smoothly slide along the thread groove when the rotating disk 53 rotates, and this sliding movement is closely related to the rotation of the rotating disk 53 and cooperates with each other. When the rotating disk 53 rotates, the convex block 59 will rotate with the rotating disk 53 and apply a horizontal thrust to the push rod 55, thereby driving the push rod 55 to move slowly forward. The output end of the motor 3 is fixed with a connecting rod 510, the end of the connecting rod 510 away from the motor 3 is fixed with a suction cup 511, the suction cup 511 is communicated with the connecting rod 510, the connecting rod 510 passes through the first gear 512, and the through part is rotatably connected. As the rotating disk 53 continues to rotate, the positioning rod 57 gradually converges towards the center along the guide groove 56. While converging, the positioning rod 57 will come into contact with and interact with the inclined surface of the first gear 512. When the positioning rod 57 applies a thrust to the inclined surface of the first gear 512, the first gear 512 will slide towards the direction of the motor 3. A sealing block 513 passes through the connecting rod 510, and the through part is slidably connected. A guide rod 514 is fixed on the outer wall of the sealing block 513, and a limiting rod 515 is fixed on the outer wall of the guide rod 514. The limiting rod 515 passes through the side wall of the first gear 512, and the through part is rotatably connected. While the first gear 512 slides,The guide rod 514 will also slide along the corresponding second thread groove 516. The outer wall of the connecting rod 510 is provided with a second thread groove 516. The inner wall of the second thread groove 516 is slidably connected to the outer wall of the guide rod 514. The proofreading device 5 drives the rotating disk 53 to rotate by turning the handle 54, and further drives the positioning rod 57 to be retracted, so that the high-precision optical lens is repositioned so that its center can be just aligned with the rotating shaft of the motor 3. When the positioning rod 57 is retracted, the high-precision optical lens can be pushed onto the suction cup 511. The retraction of the positioning rod 57 drives the first gear 512 to retreat, and at the same time drives the sealing block 513 in the center to slide, so that the suction cup 511 and the optical lens are in a hollow state, which makes the suction more firm and will not easily cause wear to the lens.

[0030] When the present embodiment is working, when the operator turns the handle 54, the handle 54 will immediately respond to this operation, and by virtue of the stable and tight connection structure between the handle 54 and the rotating disk 53, the handle 54 will immediately start to drive the rotating disk 53 closely connected thereto to rotate around the axis. In the process of the rotating disk 53 starting to rotate, since one end of the positioning rod 57 is restricted in the pre-designed guide groove 56, it will slide along the path defined by the guide groove 56. At the same time, it will slide along the first thread groove 58 adapted thereto, so that the protrusion 59 can slide smoothly along the thread groove when the rotating disk 53 rotates, and this sliding motion is closely related to the rotation of the rotating disk 53 and cooperates with each other. When the rotating disk 53 rotates, the protrusion 59 will rotate with the rotating disk 53. Due to the interaction between the protrusion 59 and the first thread groove 58, the protrusion 59 continues to slide along the first thread groove 58. In this process, the protrusion 59 relies on its own sliding and the interaction with the push rod 57. When the first gear 512 slides, the guide rod 514 also slides along the corresponding second thread groove 516, so that the guide rod 514 moves along the second thread groove 516, and when the guide rod 514 moves in the second thread groove 516, the guide rod 514 is squeezed and rotated in the opposite direction, so that the limiting rod 515 can be driven to reverse, and when the limiting rod 515 rotates, the first gear 512 can be rotated.

[0031] See also Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, it further includes a impurity removal device 6 and a limiting device 7. The impurity removal device 6 includes a fixed block 61, a grinding tool 62, a replaceable grinding head 63, a transmission belt 64, a second gear 65, a wave cam 66, a limiting plate 67, a cleaning block 68, a long plate 69, a long rod 610, a hinged rod 611, a short rod 612 and a knocking block 613. The fixed block 61 is fixedly connected to the upper surface of the processing table 1. The upper surface of the fixed block 61 is hinged with a grinding tool 62. The inner wall of the grinding tool 62 is fixed with a replaceable grinding head 63. The outer wall of the first gear 512 is engaged with a transmission belt 64. After the first gear 512 starts to rotate, it transmits the power generated by its own rotation to the transmission belt 64. The inner wall of the transmission belt 64 is also engaged with a second gear 65. After receiving the power, the transmission belt 64 transmits the transmission power to the second gear 65. The second gear 65 is fixedly connected to the side wall of the grinding tool 62. When the second gear 65 rotates, it can drive the grinding tool 62 to rotate around the common axis together. A sliding rod is fixed on the upper surface of the processing table 1. The sliding rod penetrates through the first spring. The lower end of the first spring is fixedly installed on the upper surface of the processing table 1. The upper end of the first spring is fixed with a limiting plate 67. The first spring also applies a pulling force to the limiting plate 67, so that the limiting plate 67 slides downward along the sliding rod. A push block is fixed to the bottom surface of the limiting plate 67. When the limiting plate 67 slides downward, it drives the connected push block to move downward along the same direction. A grinding plate slides on the bottom surface of the push block. During the downward movement of the push block, it will apply a thrust force towards the center direction to the grinding plate. After receiving this thrust force, the grinding plate moves stably towards the center direction. A wave cam 66 is fixed on the side of the second gear 65 away from the grinding tool 62. A sliding rod is fixed on the upper surface of the processing table 1. The sliding rod penetrates through the first spring. The lower end of the first spring is fixedly installed on the upper surface of the processing table 1. The upper end of the first spring is fixed with a limiting plate 67. A cleaning block 68 penetrates through the limiting plate 67, and the penetration part is slidably connected to the cleaning block 68. A long plate 69 is fixed to the side wall of the cleaning block 68. A long rod 610 is fixed to the bottom surface of the long plate 69. The bottom end of the long rod 610 fits with the inner wall of the wave groove of the wave cam 66. A hinged rod 611 is hinged to the bottom surface of the cleaning block 68. One end of the hinged rod 611 away from the cleaning block 68 is hinged with a short rod 612. The short rod 612 is hinged to the side wall of the limiting plate 67. A knocking block 613 is fixed to the side wall of the short rod 612. This impurity removal device 6 drives the second gear 65 to rotate through the rotation of the first gear 512. During operation, the grinding tool 62 can be lowered, and at the same time of lowering the grinding tool 62, it drives the rotation of the wave cam 66. When the wave cam 66 rotates, it drives the long rod 610 to make a reciprocating motion along the wave groove. The long rod 610 drives the long plate 69 to move. The long plate 69 drives the cleaning block 68 to slide left and right to clean the replaceable grinding head 63. The limiting plate 67 is pulled down by the combined action of the pulling force of the first spring and gravity, driving the push block to push the grinding plate to the other side of the optical lens. The motor 3 is started. The motor 3 drives the optical lens to rub on the replaceable grinding head 63 and the grinding plate.The optical lens is polished on both sides simultaneously to improve work efficiency and stability. The limiting device 7 includes a second spring 71, a limiting frame 72, a limiting hole 73 and a cleaning block 68. The bottom end of the second spring 71 is fixed to the inner wall of the fixed block 61, and the upper end of the second spring 71 is fixed with a limiting frame 72. When the limiting frame 72 slides downward, the second spring 71 will be compressed, causing the second spring 71 to store elastic potential energy. A limiting hole 73 is provided on the side wall of the grinding tool 62. When the limiting frame 72 slides downward, its structural shape can be accurately matched with the limiting hole 73, and the limiting hole 73 will be accurately latched. A cleaning block 68 passes through the limiting plate 67, and the passing part is rotatably connected. The cleaning block is made of rubber material with certain elasticity and friction, and a brush and a sponge are fixed on its surface. When the replaceable grinding head 63 passes over the cleaning block, the fine bristles of the brush can penetrate into the texture of the replaceable grinding head 63 by virtue of their contact with the surface of the replaceable grinding head 63 and the relative movement, and sweep down the larger particle powders attached to it through mechanical friction and cleaning action. The sponge, by using its own porous and adsorbent material characteristics, can adsorb those fine residual powders generated by grinding. Through this cooperative mechanism of the brush and the sponge, the powders remaining after the work of the replaceable grinding head 63 can be cleaned more thoroughly. The limiting device 7 can detect whether the replaceable grinding head 63 is severely worn through the connection between the limiting frame 72 and the limiting plate 67, and lock the grinding tool 62 when the replaceable grinding head 63 is severely worn, preventing the staff from continuing to use it unknowingly and affecting the processing accuracy of the optical lens. Moreover, after using the grinding tool 62, the replaceable grinding head 63 can be cleaned when the grinding tool 62 is returned to its position, avoiding the residual particles on the replaceable grinding head 63 from affecting the next processing and polishing.

[0032] During the operation of this embodiment: After the first gear 512 starts to rotate, it transmits the power generated by its own rotation to the transmission belt 64. After receiving the power, the transmission belt 64 transmits the power to the second gear 65. After receiving the power transmitted by the transmission belt 64, the second gear 65 rotates. Since the second gear 65 is fixedly connected to the grinding tool 62, the second gear 65 rotates along with the grinding tool 62 during rotation, further driving the wave cam 66 to rotate. When the wave cam 66 rotates, because the long rod 610 slides along its wave groove, as the wave cam 66 rotates, the long rod 610 reciprocates. When the long rod 610 reciprocates, it drives the long plate 69 to reciprocate. The long plate 69 drives the cleaning block 68 to slide left and right, thereby cleaning the replaceable grinding head 63. When the grinding tool 62 descends to a specific position, the replaceable grinding head 63 no longer applies an upward pushing force to the limiting plate 67. At this time, the first spring starts to take effect and pulls the limiting plate 67. The limiting plate 67 starts to slide downward along the sliding rod. The downward sliding of the limiting plate 67 will drive the push block connected to it to move downward together. During the downward movement of the push block, it will apply a thrust force towards the center direction to the grinding plate. After receiving this thrust force, the grinding plate moves towards the center direction, and thus can perform synchronous grinding on the other side of the high-precision optical lens. After the grinding is completed, rotate the handle 54 in the reverse direction, and the grinding tool 62 will rise under the action of reverse rotation as before. During the rising process, the grinding tool 62 will drive the replaceable grinding head 63 to wipe across the cleaning block. The cleaning block is made of rubber material with certain elasticity and friction, and a brush and a sponge are fixed on its surface. When the replaceable grinding head 63 passes over the cleaning block, the contact between the brush and the surface of the replaceable grinding head 63 sweeps down the larger particle powders attached to it, and the sponge adsorbs the fine residual powders generated by grinding, and can clean the powders remaining after the work of the replaceable grinding head 63 more thoroughly. After long-term use of this grinding device, the replaceable grinding head 63 is worn. When the replaceable grinding head 63 is worn to a certain extent, the overall length thereof will change. This change will cause the position of the limiting plate 67 to drop to a certain extent. As the limiting plate 67 drops, the limiting frame 72 in contact with it will also slide downward. While the limiting frame 72 slides downward, it will compress the second spring 71, causing the second spring 71 to store elastic potential energy. When the limiting frame 72 slides to the lowest position, it will latch the limiting hole 73, making the grinding tool 62 unable to be lowered for work anymore. Only when the operator replaces the worn replaceable grinding head 63 and adjusts the new grinding head to the previous height can the work continue normally.

[0033] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
