Description

Technical Field

[0001] This utility model belongs to the field of optical lens processing technology, and in particular relates to a grinding device for optical lens processing. Background Technology

[0002] Optical lenses are mostly circular glass lenses. During the processing of optical lenses, their outer edges need to be ground, i.e., edge grinding. Existing grinding equipment mostly uses a grinding disc in a single direction for grinding. For lenses that require grinding with inclined edges, the position of the lens or grinding disc needs to be manually adjusted during inclined grinding, which is time-consuming and labor-intensive, and the grinding uniformity is not good, thus reducing the efficiency of lens grinding to a certain extent. Utility Model Content

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a grinding device for optical lens processing.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A grinding device for optical lens processing includes an operating table, a vacuum chuck fixedly attached to the upper side of the operating table, and a grinding disc that can rotate circumferentially along the vacuum chuck and is vertically arranged above the operating table. A fixed plate located behind the grinding disc is vertically connected to the upper side of the operating table. A first telescopic mechanism is fixedly attached to the fixed plate, and a first connecting plate is fixedly attached to the telescopic end of the first telescopic mechanism. A first motor arranged perpendicular to the axial direction of the grinding disc is horizontally fixed to the first connecting plate.

A positioning plate that can move longitudinally is provided above the vacuum chuck.

[0006] Furthermore, the operating platform includes a box with an opening on the upper side. Inside the box, a main gear and a gear ring are horizontally meshed together. A third motor is fixedly connected to the bottom of the box corresponding to the main gear. The output shaft of the third motor is fixedly connected to the main gear. A vacuum generator is located inside the gear ring. A mounting bracket is also fixedly connected inside the box. The mounting bracket includes a mounting plate horizontally set on the upper side of the gear ring and a mounting ring fixed to the bottom of the mounting plate. The mounting ring is located inside the gear ring. A vacuum suction cup is fixedly connected to the upper side of the mounting plate, and its bottom is connected to an air pipe that passes through the mounting plate and the bottom of the box. The end of the air pipe is connected to the vacuum generator. A fixing plate is fixedly connected to the upper side of the gear ring corresponding to the outer side of the mounting plate.

[0007] Furthermore, a bearing is provided between the outer wall of the mounting ring and the inner wall of the gear ring.

[0008] Furthermore, an operating plate is fixed to the opening on the upper side of the housing. A through groove is provided on the operating plate. The mounting plate is located in the through groove and its upper surface is flush with the upper surface of the operating plate. The teeth of the gear ring are blocked by the operating plate. An annular groove is formed between the inner wall of the through groove and the mounting plate. The fixing plate is located in the annular groove.

[0009] Furthermore, an inverted L-shaped upright plate is vertically fixed to the upper side of the operating panel, and a second telescopic mechanism is fixed downward on the horizontal section at the top of the upright plate. A positioning plate is fixed to the telescopic end at the bottom of the second telescopic mechanism.

[0010] Furthermore, a protective layer is bonded to the bottom of the positioning plate.

[0011] Furthermore, an annular support plate is fixed to the outer wall of the lower end of the vacuum suction cup. The support plate is fixed to the upper side of the mounting plate, and the vertical projection corresponding to the outer wall of the support plate is located inside the vertical projection corresponding to the outer wall of the vacuum suction cup.

[0012] Furthermore, a dust suction hood is provided on the side of the annular groove near the inner wall of the through groove. The dust suction hood is connected to the exhaust fan through an air duct, and the height of the dust suction hood and the air duct is lower than the bottom of the first telescopic mechanism.

[0013] Furthermore, each of the four corners of the bottom of the control panel is fixed with a column.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The optical lens grinding device of this utility model, when in use, places the lens on the upper side of the vacuum suction cup, which then adsorbs it.

[0030] The operating table 1 includes a box 101 with an opening on the upper side. Inside the box 101, a main gear and a gear ring 11 are horizontally meshed together. A third motor 15 is fixedly connected to the bottom of the box 101 at the position corresponding to the main gear. The output shaft of the third motor 15 is fixedly connected to the main gear. A vacuum generator is located inside the gear ring 11. A mounting bracket 12 is also fixedly connected inside the box 101. The mounting bracket 12 includes a mounting plate 1201 horizontally set on the upper side of the gear ring 11 and a mounting ring 1202 fixedly connected to the bottom of the mounting plate 1201. The mounting ring 1202 is located inside the gear ring 11. A vacuum suction cup 2 is fixedly connected above the mounting plate 1201, and its bottom is connected to an air pipe 10 that passes through the mounting plate 1201 and the bottom of the box 101. The end of the air pipe 10 is connected to the vacuum generator. A fixing plate 4 is fixedly connected to the upper side of the gear ring 11 at the position corresponding to the outer side of the mounting plate 1201. In this embodiment, the gear ring 11 is limited by the mounting ring 1202; through holes are provided at the middle of the mounting plate 1201 and at the bottom of the housing 101 corresponding to the middle of the mounting plate 1201. The air pipe 10 passes through the through holes of the mounting plate 1201 and the bottom of the housing 101 and connects to the vacuum generator located below the housing 101. In this embodiment, the lens is placed on the upper side of the vacuum suction cup 2, and the vacuum generator is started to adsorb the lens onto the vacuum suction cup 2. The third motor 15 drives the main gear to rotate, which drives the gear ring 11 to rotate, and then drives the grinding disc 3 to rotate with the gear ring 11, so that the grinding disc 3 rotates circumferentially around the vacuum suction cup 2. In this embodiment, multiple fixing ears 1203 with threaded holes are evenly provided circumferentially at the bottom of the inner sidewall of the mounting ring 1202. Bolt mounting holes are provided at the bottom of the housing 101 corresponding to the threaded holes. The fixing ears 1203 and the bottom of the housing 101 are fixed together by bolts and bolt mounting holes and threaded holes, thereby realizing the fixed installation of the mounting bracket 12 in the housing. In this embodiment, the mounting bracket 12 is a one-piece molded structure.

[0031] A bearing 13 is provided between the outer wall of the mounting ring 1202 and the inner wall of the gear ring 11. The mounting ring 1202 limits the position of the gear ring 11, and the bearing 13 enables the gear ring 11 to rotate more smoothly.

[0032] An operating plate 102 is fixedly connected to the opening on the upper side of the housing 101. A circular through groove 1021 is formed on the operating plate 102. A mounting plate 1201 is located in the through groove 1021, with its upper surface flush with the upper surface of the operating plate 102. The teeth of the gear ring 11 are shielded by the operating plate 102. An annular groove 16 is formed between the inner wall of the through groove 1021 and the mounting plate 1201, and a fixing plate 4 is located in the annular groove 16. In this embodiment, the operating plate 102 shields and longitudinally limits the gear ring 11 and the driven gear, resulting in a neat appearance and improved safety, preventing foreign objects from being caught between the main gear and the gear ring 11. In this embodiment, the annular groove 16 ensures that the fixing plate 4 can rotate with the gear ring 11. In this embodiment, the operating plate 102 is fixed to the upper side of the housing 101 by screws.

[0033] An inverted L-shaped upright plate 19 is vertically fixed to the upper side of the operation panel 102. A second telescopic mechanism 18 is fixed downwards on the horizontal section at the top of the upright plate 19. A positioning plate 17 is fixed to the telescopic end at the bottom of the second telescopic mechanism 18. In this embodiment, the upper side of the positioning plate 17 is provided with an integrally formed mounting block 1701 with a mounting hole at the top. A first connecting hole is horizontally provided on the mounting block 1701. The mounting block 1701 is sleeved at the telescopic end of the bottom of the second telescopic mechanism 18 through the mounting hole. A second connecting hole is provided at the telescopic end of the bottom of the second telescopic mechanism 18 corresponding to the first connecting hole. The second connecting hole and the telescopic end of the bottom of the second telescopic mechanism 18 are fixed together by bolt and nut pair with the first connecting hole and the second connecting hole. In this embodiment, after the lens is placed and adsorbed on the vacuum suction cup 2, the positioning plate 17 is driven to move downwards by the second telescopic mechanism 18 until the positioning plate 17 presses the lens, further horizontally positioning the lens and preventing tilting or displacement during lens polishing.

[0034] A protective layer is adhered to the bottom of the positioning plate 17. In this embodiment, the protective layer is a rubber protective layer, which prevents the lens from being scratched when the positioning plate 17 is pressed against the upper side of the lens.

[0035] An annular support plate 14 is fixedly attached to the outer wall of the lower end of the vacuum suction cup 2. The support plate 14 is fixed to the upper side of the mounting plate 1201, and the vertical projection of the support plate 14 to the outer wall of the circumference is located inside the vertical projection of the vacuum suction cup 2 to the outer wall of the circumference, ensuring that the vacuum suction cup 2 adsorbs the lens, and the grinding disc 3 does not grind the support plate 14 when grinding the edge of the lens. In this embodiment, multiple countersunk holes are evenly opened on the upper side of the support plate 14, and threaded holes are opened on the upper side of the mounting plate 1201 at the corresponding countersunk holes. The support plate 14 and the mounting plate 1201 are fixed together by bolts and the matching of countersunk holes and threaded holes. With the support plate 14 in cooperation with the positioning plate 17, the lens and the vacuum suction cup 2 are horizontally pressed against the upper side of the support plate 14 under the action of the positioning plate 17, further ensuring the horizontal positioning of the lens.

[0036] A dust suction hood 20 is provided on one side of the annular groove 16 near the inner wall of the through groove 1021 to prevent the position of the dust suction hood 20 from affecting the rotation of the fixing plate 4 with the gear ring 11. The dust suction hood 20 is connected to the exhaust fan through the air duct 21, and the height of the dust suction hood 20 and the air duct 21 is lower than the bottom of the first telescopic mechanism 5 to avoid affecting the rotation of the first telescopic mechanism 5 with the gear ring 11. In this embodiment, the exhaust fan can be placed on the ground. In this embodiment, the air duct 21 is fixed to the operating plate 102 by the cooperation of the Z-shaped positioning block 22 and screws, thereby positioning the dust suction hood 20.

[0037] Each of the four corners of the bottom of the control panel 1 is fixed with a column 23.

[0038] In this embodiment, the first telescopic mechanism 5 and the second telescopic mechanism 18 are electric telescopic rods.

[0039] The working process of this embodiment is as follows:

[0040] In use, the lens is placed on the upper side of the vacuum suction cup 2. The vacuum generator controls the vacuum suction cup 2 to adsorb the lens, and controls the second telescopic unit to move the positioning plate 17 downward until the lens and the vacuum suction cup 2 are horizontally pressed against the upper side of the support plate 14. According to the actual processing requirements, the tilt angle and horizontal position of the grinding disc 3 are adjusted to grind the edge of the lens. Specifically, the horizontal position of the grinding disc 3 is adjusted by the first telescopic mechanism 5, and the first motor 7 rotates to drive the second connecting plate 8 to rotate at a certain angle, thereby adjusting the tilt angle of the grinding disc 3. Finally, the second motor 9 drives the grinding disc 3 to rotate, and the third motor 15 drives the main gear to rotate, driving the gear ring 11 to rotate, thereby driving the fixing plate 4 to rotate with the gear ring 11, so that the grinding disc 3 rotates around the vacuum suction cup 2, so that the grinding disc 3 grinds while rotating on its own and rotates around the vacuum suction cup 2, thus completing the circumferential grinding of the lens.

[0041] During the polishing process, the exhaust fan is turned on, and the dust suction hood 20 sucks up the debris in the annular groove 16 to ensure that the gear ring 11 rotates smoothly.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
