[0002] Orthokeratology lenses are made of rigid gas permeable (RGP) contact lens material, commonly known as RGP material. "Orthokeratology lenses" are actually corneal reshaping lenses.
[0003] Rigid gas permeable contact lenses are a type of contact lens, while rigid orthokeratology lenses are small in size and are generally manufactured by single-point diamond lathe machining. After injection molding, the lenses need to undergo polishing and other processing steps.
[0004] Currently, rigid gas permeable lenses (RGP lenses) are small in size and have curved surfaces on both sides, making them difficult to clamp and further process. Therefore, there is a lack of a clamping fixture in the existing production process that can hold the lens without damaging the eye and without causing it to shift during processing. Here, we provide a clamping and fixing device for RGP lens processing. Summary of the Invention

[0017] This invention provides a clamping and fixing device for processing rigid gas reshaping lenses (RGRs).

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0027] Please see Figures 1-5This invention provides a clamping and fixing device for processing rigid gas permeable (RGP) lenses, comprising a base plate 1; a support frame plate 12 is fixedly connected to the top of the base plate 1; a first electric slide rail 14 is fixedly connected to the bottom of the support frame plate 12; a positioning base plate 13 is slidably connected to the base plate 1; a first air pump 18 is fixedly connected inside the positioning base plate 13; a lens body limiting block 211 is fixedly connected to the top of the positioning base plate 13; a first air groove 19 is formed inside the lens body limiting block 211; a first suction positioning tube 20 is fixedly connected inside the lens body limiting block 211, and the first suction positioning tube 20 is connected to the first air groove 19; and a rigid gas permeable (RGP) lens 21 is mounted on the lens body limiting block 211.
[0028] During operation, rigid gas permeable (RGP) lenses are small in size and have curved surfaces on both sides, making them difficult to clamp for further processing. Therefore, the current production process lacks a clamping fixture that can hold the lens without damaging the eye and prevent it from shifting during processing. During operation, the RGP lens 21 is installed on the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by the pump flows through the first air groove 19 to the first suction positioning tube 20. This negative pressure allows the RGP lens 21 to adhere to the lens retaining block 211. The lens retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the RGP lens 21's position and preventing damage to the eye. Damage to the orthokeratology lens 21 can also be addressed by fixing the position of the rigid gas permeable (RGB) lens 21, facilitating processing by the technician. Activating the first electric slide rail 14 causes the first electric slider 15 to slide, which in turn causes the first cylinder 16 to slide. The sliding of the first cylinder 16 then causes the positioning shell 17 to slide, positioning the shell 17 above the RGB lens 21. The first cylinder 16 then causes the positioning shell 17 to slide downwards, covering the top surface of the RGB lens 21. The positioning shell 17, in conjunction with the lens limiting block 211, clamps and fixes the position of the RGB lens 21. To facilitate processing by staff, after the rigid gas permeable (RGP) lens body 21 is processed, the positioning shell 17 is moved away from the RGP lens body 21. Then, the first suction pump 18 is turned off and the first air pump 23 is started. The airflow generated by the first air pump 23 enters the first suction positioning tube 20 through the first exhaust channel 22 and is discharged. This can blow the RGP lens body 21 up, preventing it from sticking tightly to the surface of the lens body limiting block 211, making it easier to remove. The liquid tank 28 is filled with lubricating fluid. After the positioning shell 17 finishes working, the first electric slider 15 and the first cylinder 16 work together to move the positioning shell 17 into the liquid tank 28, ensuring the wettability of the inner wall of the positioning shell 17 and preventing it from becoming too dry. Dryness causes wear and tear on the surface of the rigid gas permeable (RGP) lens 21. After the RGP lens 21 is removed from the lens retainer block 211, a water pump installed inside the liquid tank 28 sprays lubricant from the spray head 29 onto the surface of the lens retainer block 211 through the spray head 29, ensuring the wettability of the RGP lens 21 and reducing the wear and tear caused by the drying of the lens retainer block 211. Depending on the processing method of the RGP lens 21, the top of the RGP lens 21 can be fixed in different ways, causing the second electric slider 24 to move above the RGP lens 21, thereby moving the second cylinder 25 and the positioning ring 27.Activating cylinder 25 causes positioning plate 26 to slide downwards. This sliding motion of positioning plate 26 moves positioning ring 27, which then engages with rigid gas permeable (RGB) lens 21, facilitating processing of the top surface of RGB lens 21. After processing, electric slider 31 slides along electric slide rail 30 to one side of positioning base 13. Activating cylinder 40 causes positioning base 13 to slide, which in turn causes RGB lens 21 to slide, moving it below the gripper 33. Electric push rod 32 then operates, causing gripper 33 to slide downwards, moving positioning suction tube 34 above RGB lens 21. Air pump 38 operates, generating negative pressure. Gas is adsorbed onto the surface of the rigid gas permeable (RGP) lens 21 through the second positioning suction tube 34. Multiple sets of second positioning suction tubes 34 are located at the bottom of the clamping box 33, allowing for precise positioning of the RGP lens 21. At this time, the first electric push rod 32 moves the RGP lens 21 away from the positioning base 13. The third electric slider 31 slides on the second electric slide rail 30, transporting the RGP lens 21. After the RGP lens 21 is adsorbed and fixed by the second positioning suction tube 34, the second electric push rod 36 moves the lens positioning block 37 to the left, moving it below the RGP lens 21. This, combined with the first electric push rod 32, secures the RGP lens 21 onto the surface of the lens positioning block 37. The cooperation between the lens positioning block 37 and the second positioning suction tube 34 ensures the fixed position of the rigid gas permeable (RGP) lens 21, preventing positional changes during transport. When the RGP lens 21 needs to detach from below the second positioning suction tube 34, the first electric push rod 32 moves the second positioning suction tube 34 upward, causing the lens positioning block 37 to slide away from the RGP lens 21. At this time, the second air pump 39 is activated, and the gas generated by the second air pump 39 enters the second positioning suction tube 34. The gas is then discharged from the second positioning suction tube 34, blowing off the RGP lens 21, completing the detachment of the RGP lens 21 from the second positioning suction tube 34. The negative pressure of the gas generated by the operation of the first suction pump 18 passes through the first air tank 19, and the negative pressure of the gas passes through a... The gas flows from the No. 19 air tank to the No. 1 suction positioning tube 20, creating a negative pressure that allows the rigid gas (RGB) orthokeratology lens 21 on the lens body limiting block 211 to be adsorbed. The lens body limiting block 211 has multiple sets of No. 1 suction positioning tubes 20 inside, thereby improving the stability of the RGB lens 21's position. This prevents damage to the RGB lens 21 and also fixes its position, facilitating processing by the technician. The positioning shell 17 slides above the RGB lens 21, and the No. 1 cylinder 16 slides the positioning shell 17 downwards, so that it covers the top surface of the RGB lens 21, thus fixing its position.The positioning shell 17, in conjunction with the lens limiting block 211, can clamp and fix the position of the rigid gas permeable lens 21, making it easier for staff to process it.
[0029] Furthermore, such as Figure 3 As shown, the bottom end of the first electric slide rail 14 is slidably connected to the first electric slider 15; the bottom end of the first electric slider 15 is fixedly connected to the first cylinder 16; the bottom end of the first cylinder 16 is fixedly connected to the positioning shell 17, and the bottom end of the positioning shell 17 is equipped with the rigid corneal reshaping lens body 21.
[0030] During operation, the rigid gas reshaping lens 21 is installed onto the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by its operation flows through the first air groove 19 to the first suction positioning tube 20. This negative pressure allows the rigid gas reshaping lens 21 to be adsorbed onto the lens retaining block 211. The lens retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the rigid gas reshaping lens 21's position. This prevents damage to the lens and also fixes its position, facilitating processing by the operator. The first electric slide rail 14 is activated, causing the first electric slider 15 to slide. The sliding of the first electric slider 15 causes the first cylinder 16 to slide, which in turn causes the positioning shell 17 to slide. The positioning shell 17 is slid above the rigid gas permeable (RGP) lens 21. The first cylinder 16 then slides the positioning shell 17 downwards, allowing it to cover the top surface of the RGP lens 21. The positioning shell 17 fixes the position of the RGP lens 21. The positioning shell 17, in conjunction with the lens retaining block 211, clamps and fixes the RGP lens 21, making processing easier for workers. After the RGP lens 21 is processed, the positioning shell 17 is moved away from the RGP lens 21. The first suction pump 18 is then turned off, and the first air pump 23 is started. The airflow generated by the first air pump 23 enters the first suction positioning tube 20 through the first exhaust slot 22 and is discharged, blowing the RGP lens 21 upwards and preventing it from sticking tightly to the surface of the lens retaining block 211, thus facilitating the removal of the RGP lens 21.
[0031] Furthermore, such as Figure 4 As shown, a second electric slide rail 30 is fixedly connected to the bottom end of the support frame plate 12; a third electric slider 31 is slidably connected to the bottom end of the second electric slide rail 30; a first electric push rod 32 is fixedly connected to the bottom end of the third electric slider 31; a clamping box 33 is fixedly connected to the bottom end of the first electric push rod 32; a second air pump 38 is fixedly connected inside the clamping box 33; and a second positioning suction tube 34 is fixedly connected to the bottom end of the clamping box 33.
[0032] During operation, after the rigid gas permeable (RGP) lens body 21 is processed, the third electric slider 31 slides to one side of the positioning base 13 via the second electric slide rail 30. The third cylinder 40 is activated to slide the positioning base 13. The sliding of the positioning base 13 causes the RGP lens body 21 to slide together, thereby moving the RGP lens body 21 to below the gripper 33. The first electric push rod 32 operates to slide the gripper 33 downward, thereby moving the second positioning suction tube 34 to the RGP lens body 21. Above, the second air pump 38 operates to generate negative pressure, and the gas is adsorbed onto the surface of the rigid gas reshaping lens 21 through the second positioning suction tube 34. The bottom of the clamping box 33 is equipped with multiple sets of second positioning suction tubes 34, which can limit the position of the rigid gas reshaping lens 21. At this time, the first electric push rod 32 operates to move the rigid gas reshaping lens 21 away from the positioning base 13, and the third electric slider 31 slides on the second electric slide rail 30 to transport the rigid gas reshaping lens 21.
[0033] Furthermore, such as Figure 3 As shown, a No. 1 air pump 23 is fixedly connected to one side of the No. 1 air pump 18 inside the positioning chassis 13; a No. 1 exhaust groove 22 is opened inside the mirror body limiting block 211, and the No. 1 exhaust groove 22 is connected to the No. 1 air suction positioning pipe 20.
[0034] During operation, the rigid gas reshaping lens 21 is installed onto the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by the pump flows through the first air groove 19 towards the first suction positioning tube 20. This negative pressure allows the rigid gas reshaping lens 21 to adhere to the retaining block 211. The retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the rigid gas reshaping lens 21's position. This prevents damage to the lens and also ensures proper positioning of the rigid gas reshaping lens. The position of the orthokeratology lens 21 is fixed to facilitate the processing of the rigid orthokeratology lens 21 by the staff. After the rigid orthokeratology lens 21 is processed, the positioning shell 17 is moved away from the rigid orthokeratology lens 21. The first suction pump 18 is turned off and the first air pump 23 is started. The airflow generated by the first air pump 23 enters the first suction positioning tube 20 through the first exhaust groove 22 and is discharged. This can blow the rigid orthokeratology lens 21 up, preventing the rigid orthokeratology lens 21 from sticking tightly to the surface of the lens limiting block 211, making it easier to remove the rigid orthokeratology lens 21.
[0035] Furthermore, such as Figure 3 As shown, the bottom end of the first electric slide rail 14 is slidably connected to the second electric slider 24; the bottom end of the second electric slider 24 is fixedly connected to the second cylinder 25; the bottom end of the second cylinder 25 is fixedly connected to the positioning plate 26; and the bottom end of the positioning plate 26 is fixedly connected to the positioning ring 27.
[0036] During operation, the rigid gas reshaping lens 21 is installed onto the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by the pump flows through the first air groove 19 to the first suction positioning tube 20. This negative pressure allows the rigid gas reshaping lens 21 to adhere to the retaining block 211. The retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the rigid gas reshaping lens 21's position. This prevents damage to the lens and also helps to fix its position, facilitating the operator's treatment of the rigid gas reshaping lens. The rigid gas permeable lens 21 is processed by activating the first electric slide rail 14 to slide the first electric slider 15. The sliding of the first electric slider 15 causes the first cylinder 16 to slide, which in turn causes the positioning shell 17 to slide. The positioning shell 17 slides above the rigid gas permeable lens 21. The first cylinder 16 then causes the positioning shell 17 to slide downward, so that the positioning shell 17 covers the top surface of the rigid gas permeable lens 21. The positioning shell 17 fixes the position of the rigid gas permeable lens 21. The positioning shell 17, together with the lens limiting block 211, can clamp and fix the position of the rigid gas permeable lens 21, making it more convenient for the staff to process.
[0037] Furthermore, such as Figure 5 As shown, a second air pump 39 is fixedly connected to one side of the second air pump 38 inside the clamping box 33, and a second positioning suction tube 34 is provided at the bottom end of the second air pump 39.
[0038] During operation, after the rigid gas permeable (RGP) lens body 21 is processed, the third electric slider 31 slides to one side of the positioning base 13 via the second electric slide rail 30. The third cylinder 40 is activated, causing the positioning base 13 to slide. This sliding of the positioning base 13 causes the RGP lens body 21 to slide as well, moving it below the gripper box 33. The first electric push rod 32 operates, causing the gripper box 33 to slide downwards, thus moving the second positioning suction tube 34 above the RGP lens body 21. The second air pump 38 operates, generating negative pressure. The gas is then drawn onto the surface of the RGP lens body 21 through the second positioning suction tube 34. Multiple sets of second positioning suction tubes 34 are located at the bottom of the gripper box 33, allowing for precise application of the RGP lens. The position of the orthokeratology lens 21 is defined. At this time, the first electric push rod 32 operates to move the rigid gas permeable (RGP) lens 21 away from the positioning base 13. The third electric slider 31 slides on the second electric slide rail 30 to transport the RGP lens 21. When the RGP lens 21 needs to be detached from below the second positioning suction tube 34, the first electric push rod 32 moves the second positioning suction tube 34 upward, causing the lens positioning block 37 to slide away from the RGP lens 21. At this time, the second air pump 39 is activated. The gas generated by the second air pump 39 enters the second positioning suction tube 34, and the gas is discharged from the second positioning suction tube 34 to blow off the RGP lens 21, completing the operation of detaching the RGP lens 21 from the second positioning suction tube 34.
[0039] Furthermore, such as Figure 4 As shown, a connecting plate 35 is fixedly connected to the side end of the clamping box 33; a second electric push rod 36 is fixedly connected to one end of the connecting plate 35; a lens positioning block 37 is fixedly connected to the side end of the second electric push rod 36, and a rigid gas permeable lens 21 is installed on the lens positioning block 37.
[0040] During operation, after the rigid gas permeable (RGP) lens body 21 is processed, the third electric slider 31 slides to one side of the positioning base 13 via the second electric slide rail 30. The third cylinder 40 is activated, causing the positioning base 13 to slide. This sliding of the positioning base 13 causes the RGP lens body 21 to slide as well, moving it below the gripper box 33. The first electric push rod 32 operates, causing the gripper box 33 to slide downwards, thus moving the second positioning suction tube 34 above the RGP lens body 21. The second air pump 38 operates, generating negative pressure. Gas is drawn onto the surface of the RGP lens body 21 through the second positioning suction tube 34. The bottom of the gripper box 33 is equipped with multiple sets of second positioning suction tubes 34, allowing for precise application of the RGP lens. The position of the rigid gas permeable lens 21 is defined. At this time, the first electric push rod 32 operates to move the rigid gas permeable lens 21 away from the positioning base 13. The third electric slider 31 slides on the second electric slide rail 30 to transport the rigid gas permeable lens 21. After the rigid gas permeable lens 21 is attracted and fixed by the second positioning suction tube 34, the second electric push rod 36 operates to slide the lens positioning block 37 to the left, thereby moving the lens positioning block 37 to a position below the rigid gas permeable lens 21. In conjunction with the first electric push rod 32, the rigid gas permeable lens 21 is locked onto the surface of the lens positioning block 37. The cooperation between the lens positioning block 37 and the second positioning suction tube 34 can ensure the positional fixation of the rigid gas permeable lens 21 and avoid positional changes during the transportation process.
[0041] Furthermore, such as Figure 2 As shown, a liquid tank 28 is fixed to the top of the base plate 1; a positioning shell 17 is provided on one side of the liquid tank 28.
[0042] During operation, the first electric slide rail 14 is activated, causing the first electric slider 15 to slide. The sliding of the first electric slider 15 causes the first cylinder 16 to slide, which in turn causes the positioning shell 17 to slide. The positioning shell 17 slides above the rigid gas permeable (RGP) lens 21. The first cylinder 16 then causes the positioning shell 17 to slide downwards, thus covering the top surface of the RGP lens 21. The positioning shell 17 fixes the position of the RGP lens 21. The positioning shell 17, in conjunction with the lens limiting block 211, can clamp and fix the position of the RGP lens 21, making it easier for workers to process. The liquid tank 28 is filled with lubricating fluid. After the procedure, the positioning shell 17 is moved into the liquid tank 28 by the cooperation of the first electric slider 15 and the first cylinder 16, ensuring the wettability of the inner wall of the positioning shell 17 and preventing the positioning shell 17 from drying out and causing damage to the surface of the rigid gas permeable lens 21. After the rigid gas permeable lens 21 is removed from the lens limiting block 211, a water pump is installed inside the liquid tank 28. The spray head 29 operates through the water pump, and the lubricating fluid inside the liquid tank 28 is sprayed onto the surface of the lens limiting block 211 through the spray head 29, ensuring the wettability of the surface of the lens limiting block 211, thereby ensuring the wettability of the rigid gas permeable lens 21 and reducing the damage to the rigid gas permeable lens 21 caused by the drying out of the lens limiting block 211.
[0043] Furthermore, such as Figure 2 As shown, a third cylinder 40 is fixedly connected to one end of the support frame plate 12; the side end of the third cylinder 40 is connected to the positioning base 13, and the positioning base 13 is slidably connected to the bottom of the second electric slide rail 30.
[0044] During operation, after the rigid gas permeable (RGP) lens body 21 is processed, the third electric slider 31 slides to one side of the positioning base 13 via the second electric slide rail 30. The third cylinder 40 is activated to slide the positioning base 13. The sliding of the positioning base 13 causes the RGP lens body 21 to slide together, thereby moving the RGP lens body 21 to below the gripper 33. The first electric push rod 32 operates to slide the gripper 33 downward, thereby moving the second positioning suction tube 34 to the RGP lens body 21. Above, the second air pump 38 operates to generate negative pressure, and the gas is adsorbed onto the surface of the rigid gas reshaping lens 21 through the second positioning suction tube 34. The bottom of the clamping box 33 is equipped with multiple sets of second positioning suction tubes 34, which can limit the position of the rigid gas reshaping lens 21. At this time, the first electric push rod 32 operates to move the rigid gas reshaping lens 21 away from the positioning base 13, and the third electric slider 31 slides on the second electric slide rail 30 to transport the rigid gas reshaping lens 21.
[0045] Furthermore, such as Figure 2As shown, a spray head 29 is fixedly connected to the side end of the liquid tank 28, and a mirror body limiting block 211 is installed on the side end of the spray head 29.
[0046] During operation, the rigid gas reshaping lens 21 is installed onto the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by the pump flows through the first air groove 19 towards the first suction positioning tube 20. This negative pressure allows the rigid gas reshaping lens 21 to adhere to the retaining block 211. The retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the rigid gas reshaping lens 21's position. This prevents damage to the lens and also allows for better positioning. The rigid orthokeratology lens 21 is fixed in position to facilitate processing by staff. After the rigid orthokeratology lens 21 is removed from the lens retainer block 211, a water pump is installed inside the liquid tank 28. The spray head 29 operates through the water pump, and the lubricant inside the liquid tank 28 is sprayed onto the surface of the lens retainer block 211 through the spray head 29 to ensure the wettability of the surface of the lens retainer block 211, thereby ensuring the wettability of the rigid orthokeratology lens 21 and reducing the damage to the rigid orthokeratology lens 21 caused by the drying of the lens retainer block 211.
[0047] Working Principle: Rigid orthokeratology lenses are small in size and have curved surfaces on both sides, making them difficult to clamp for further processing. Therefore, current production processes lack a clamping fixture that can hold the lens without damaging the eye and prevent it from shifting during processing. During operation, the rigid orthokeratology lens 21 is installed on the lens retaining block 211. The first suction pump 18 is activated, and the negative pressure generated by the pump flows through the first air groove 19 to the first suction positioning tube 20. This negative pressure allows the rigid orthokeratology lens 21 to adhere to the retaining block 211. The retaining block 211 has multiple sets of first suction positioning tubes 20 inside, thereby improving the stability of the rigid orthokeratology lens 21's position and preventing damage to the eye. Even if the orthokeratology lens 21 is damaged, its position can still be fixed, facilitating processing by staff. Activating the first electric slide rail 14 causes the first electric slider 15 to slide, which in turn causes the first cylinder 16 to slide. The sliding of the first cylinder 16 then causes the positioning shell 17 to slide, positioning the shell above the orthokeratology lens 21. The first cylinder 16 then causes the positioning shell 17 to slide downwards, covering the top surface of the orthokeratology lens 21. The positioning shell 17, in conjunction with the lens limiting block 211, clamps and fixes the position of the orthokeratology lens 21. This makes processing easier for staff. After the rigid gas permeable (RGP) lens 21 is processed, the positioning shell 17 moves away from the RGP lens 21. Then, the first suction pump 18 is turned off and the first air pump 23 is started. The airflow generated by the first air pump 23 enters the first suction positioning tube 20 through the first exhaust groove 22 and is discharged. This can blow the RGP lens 21 up, preventing it from sticking tightly to the surface of the lens limiting block 211, making it easier to remove the RGP lens 21. The liquid tank 28 is filled with lubricating fluid. After the positioning shell 17 finishes working, the first electric slider 15 and the first cylinder 16 work together to move the positioning shell 17 into the liquid tank 28, ensuring the wettability of the inner wall of the positioning shell 17 and preventing it from becoming too dry. Dryness causes wear and tear on the surface of the rigid gas permeable (RGP) lens 21. After the RGP lens 21 is removed from the lens retainer block 211, a water pump installed inside the liquid tank 28 sprays lubricant from the spray head 29 onto the surface of the lens retainer block 211 through the spray head 29, ensuring the wettability of the RGP lens 21 and reducing the wear and tear caused by the drying of the lens retainer block 211. Depending on the processing method of the RGP lens 21, the top of the RGP lens 21 can be fixed in different ways, causing the second electric slider 24 to move above the RGP lens 21, thereby moving the second cylinder 25 and the positioning ring 27.Activating cylinder 25 causes positioning plate 26 to slide downwards. This sliding motion of positioning plate 26 moves positioning ring 27, which then engages with rigid gas permeable (RGB) lens 21, facilitating processing of the top surface of RGB lens 21. After processing, electric slider 31 slides along electric slide rail 30 to one side of positioning base 13. Activating cylinder 40 causes positioning base 13 to slide, which in turn causes RGB lens 21 to slide, moving it below the gripper 33. Electric push rod 32 then operates, causing gripper 33 to slide downwards, moving positioning suction tube 34 above RGB lens 21. Air pump 38 operates, generating negative pressure. Gas is adsorbed onto the surface of the rigid gas permeable (RGP) lens 21 through the second positioning suction tube 34. Multiple sets of second positioning suction tubes 34 are located at the bottom of the clamping box 33, allowing for precise positioning of the RGP lens 21. At this time, the first electric push rod 32 moves the RGP lens 21 away from the positioning base 13. The third electric slider 31 slides on the second electric slide rail 30, transporting the RGP lens 21. After the RGP lens 21 is adsorbed and fixed by the second positioning suction tube 34, the second electric push rod 36 moves the lens positioning block 37 to the left, moving it below the RGP lens 21. This, combined with the first electric push rod 32, secures the RGP lens 21 onto the surface of the lens positioning block 37. The cooperation between the lens positioning block 37 and the second positioning suction tube 34 ensures the fixed position of the rigid gas permeable (RGP) lens 21, preventing positional changes during transport. When the RGP lens 21 needs to detach from below the second positioning suction tube 34, the first electric push rod 32 moves the second positioning suction tube 34 upward, causing the lens positioning block 37 to slide away from the RGP lens 21. At this time, the second air pump 39 is activated, and the gas generated by the second air pump 39 enters the second positioning suction tube 34. The gas is then discharged from the second positioning suction tube 34, blowing off the RGP lens 21, completing the detachment of the RGP lens 21 from the second positioning suction tube 34. The negative pressure of the gas generated by the operation of the first suction pump 18 passes through the first air tank 19, and the negative pressure of the gas passes through a... The gas flows from the No. 19 air tank to the No. 1 suction positioning tube 20, creating a negative pressure that allows the rigid gas (RGB) orthokeratology lens 21 on the lens body limiting block 211 to be adsorbed. The lens body limiting block 211 has multiple sets of No. 1 suction positioning tubes 20 inside, thereby improving the stability of the RGB lens 21's position. This prevents damage to the RGB lens 21 and also fixes its position, facilitating processing by the technician. The positioning shell 17 slides above the RGB lens 21, and the No. 1 cylinder 16 slides the positioning shell 17 downwards, so that it covers the top surface of the RGB lens 21, thus fixing its position.The positioning shell 17, in conjunction with the lens limiting block 211, can clamp and fix the position of the rigid gas permeable lens 21, making it easier for staff to process it.
