Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically to an optical lens processing precision grinding device. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block is measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. In the process of processing the glass block into optical lenses, it needs to undergo fine grinding, which is a process after rough grinding. However, the existing fine grinding equipment requires workers to fix the lenses one by one on the fixture, which is difficult to install and disassemble, resulting in low production efficiency and inconvenience.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides an optical lens processing and fine grinding device, which has the following beneficial effects:

[0014] 1. This optical lens processing and fine grinding device uses a placement plate, placement groove, vent, air extraction cylinder, sealing plate and hydraulic cylinder in combination. This allows the operator to place the lens inside the placement groove, and then the hydraulic cylinder drives the sealing plate to move downward. The air pressure inside the hollow groove decreases, and the lens is sucked into the placement groove. This allows the fine grinding device to quickly fix and install a large number of lenses, further improving the efficiency of lens fine grinding.

[0015] 2. This optical lens processing and polishing device uses a hydraulic cylinder, a sealing plate, and an air extraction cylinder in combination. After polishing, the operator can push the sealing plate upward through the output end of the hydraulic cylinder. The sealing plate compresses the gas inside the air extraction cylinder, increasing the air pressure inside the hollow groove. The lens is then pushed out of the placement groove, which further facilitates the operator's work of recovering the polished lens, reduces the situation where the lens gets stuck in the placement groove and cannot be retrieved, and makes the operation easier for the operator.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides a technical solution: an optical lens processing and fine grinding device, including a base 1 and a housing 2 fixed to the left side of the upper surface of the base 1. A splash guard 3 is fixedly connected to the upper surface of the housing 2 to prevent grinding slurry from flowing onto the ground. Two sets of support plates 4 are fixedly connected to the inner wall of the housing 2, and a central tube 5 is rotatably connected to the inner wall of the support plates 4. By setting two sets of support plates 4, the stability of the central tube 5 during rotation is enhanced. An air extraction cylinder 6 is connected to the lower surface of the central tube 5, and a support cylinder 7 is connected to the upper surface of the central tube 5. A placement tray 8 is connected to the upper surface of the support cylinder 7, and a hollow groove 801 is provided inside the placement tray 8 for placing... Multiple placement slots 802 are formed on the upper surface of the disc 8, and the slots 802 are evenly arranged on the outer side of the disc 8, allowing the device to polish multiple lenses at once. A vent hole 803 is provided in the middle of the inner wall of the placement slot 802. A drive motor 9 is fixedly connected to the right side of the housing 2, and a rotating shaft 10 is fixedly connected to the output end of the drive motor 9. A drive wheel 11 is fixedly mounted on the outer surface of the rotating shaft 10, and a driven wheel 12 is fixedly mounted on the outer surface of the central tube 5. The driven wheel 12 and the drive wheel 11 are connected by a transmission belt 13. A sealing disc 14 is provided on the inner wall of the suction cylinder 6, and a sealing disc 14 is fixedly connected to the left side of the upper surface of the base 1. Hydraulic cylinder 15, the output end of hydraulic cylinder 15 is rotatably connected to the lower surface of sealing disc 14. This rotatable connection prevents hydraulic cylinder 15 from rotating with the vacuum pump 6, facilitating assembly. A grinding device 16 is located on the right side of the upper surface of base 1. Through the coordinated use of placement disc 8, placement groove 802, vent 803, vacuum pump 6, sealing disc 14, and hydraulic cylinder 15, the operator can place the lens inside placement groove 802. Then, the hydraulic cylinder 15 moves the sealing disc 14 downwards, reducing the air pressure inside the hollow groove 801, causing the lens to be sucked into placement groove 802. The internal structure allows for the rapid and efficient installation of a large number of lenses, further improving the efficiency of lens grinding. Through the coordinated use of hydraulic cylinder 15, sealing disc 14, and vacuum pump 6, after grinding, the operator can push the sealing disc 14 upwards via the output end of hydraulic cylinder 15. The sealing disc 14 compresses the gas inside the vacuum pump 6, increasing the air pressure inside the hollow groove 801. This pushes the lens out of the placement groove 802, facilitating the recovery of the ground lenses and reducing the likelihood of lenses getting stuck inside the placement groove 802, thus simplifying operation.

[0022] In this invention, to further facilitate the adjustment of the polishing force of the lens by the operator, the polishing device 16 includes a support platform 1601 fixedly connected to the base 1. Two sets of sliding columns 1602 are fixedly connected to the upper surface of the support platform 1601. A pressure table 1603 is slidably mounted on the outer surface of the sliding columns 1602. A rotating rod 1604 is rotatably connected to the left side of the lower surface of the pressure table 1603. A polishing disc 1605 is fixedly connected to the bottom end of the rotating rod 1604. A polishing motor 1606 is installed on the left side of the upper surface of the pressure table 1603. The output end of the polishing motor 1606 is fixedly connected to the top end of the rotating rod 1604. A counterweight rod 1607 is fixedly connected to the upper surface of the pressure table 1603. Three sets of counterweight plates 1608 are provided on the outer surface of the counterweight rod 1607, so that the operator can control the polishing force of the lens by changing the number of counterweight plates 1608.

[0023] In this invention, in order to further enhance the rotational stability of the rotating shaft 10, a fixing plate 17 is rotatably connected to the top and bottom of the outer surface of the rotating shaft 10. The left side of the fixing plate 17 is fixedly connected to the right side of the chassis 2, so that the fixing plate 17 plays a stable supporting role for the rotating shaft 10, thereby further enhancing the rotational stability of the rotating shaft 10.

[0024] In this invention, in order to further enhance the stability of the rotation of the central tube 5, a ball bearing is provided on the upper surface of the support plate 4. The support plate 4 is rotatably connected to the central tube 5 through the ball bearing. By providing the ball bearing, the stability of the rotation of the central tube 5 is further enhanced.

[0025] In this invention, in order to further enhance the stability of lens adsorption, a sealing gasket 804 is provided on the bottom inner wall of the placement groove 802. The sealing gasket 804 is made of silicone. By providing the sealing gasket, the gap between the lens and the placement groove 802 is reduced, thereby further enhancing the stability of lens adsorption.

[0026] In this invention, in order to further enhance the stability of the chassis 2 support, two sets of reinforcing ribs are fixedly connected to the bottom of the left and right sides of the chassis 2. The lower surface of the reinforcing ribs is fixedly connected to the upper surface of the base 1, so that the reinforcing ribs play a stable supporting role for the chassis 2, thereby further enhancing the stability of the chassis 2 support.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0028] In use, the lens is placed inside the placement slot 802. The hydraulic cylinder 15 is activated, causing its output end to move the sealing disc 14 downwards. This reduces the air pressure inside the hollow slot 801, drawing the lens into the placement slot 802. A counterweight 1608 is placed on the counterweight rod 1607, adjusting the pressure applied to the lens by the polishing disc 1605. The drive motor 9 is then activated, causing the output end of the drive motor 9 to rotate the rotating shaft 10. The rotating shaft 10 then rotates the drive wheel 11, which in turn rotates the driven wheel 12 via the transmission belt 13. The driven wheel 12 then rotates the driven wheel 12... The central tube 5 rotates, which drives the placement tray 8 to rotate. The lenses on the placement tray 8 pass over the grinding tray 1605 in sequence. The grinding motor 1606 is started. The output end of the grinding motor 1606 drives the rotating rod 1604 and the grinding tray 1605 to rotate. The grinding tray 1605 performs fine grinding on the lenses. After grinding, the pressure table 1603 is taken out upward. The output end of the hydraulic cylinder 15 pushes the sealing plate 14 to move upward. The sealing plate 14 compresses the gas inside the vacuum cylinder 6. The air pressure inside the hollow groove 801 increases, and the lenses are pushed out of the placement groove 802, and then the lenses are taken out.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
