Description

[0001] The invention relates to the technical field of lens polishing devices, and in particular to a spherical security camera lens polishing device. Background Art

[0002] Camera lens polishing is a precise and critical process, which directly affects the imaging quality and clarity of the camera. Camera polishing is generally divided into mechanical polishing and chemical polishing. Mechanical polishing generally requires four steps of rough polishing, fine polishing, cleaning and inspection of the lens.

[0003] The polishing operation of existing camera lenses generally fixes the lens in a specific position through a clamp, and then uses a rotating grinding plate in combination with polishing liquid, polishing powder or polishing paste to reduce defects and irregular reflections on the lens surface. Since coarse polishing, fine polishing and cleaning require different processing operations on the lens, the operator is often required to change different equipment to perform different processing operations on the lens, which is very troublesome and reduces the polishing efficiency of the lens.

DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: referring to Figure 1 - Fig.14 The present invention discloses a spherical security camera lens polishing device, comprising a base 1 and a support leg 2, wherein the support leg 2 is fixedly mounted at the center of the bottom side of the base 1, and a polishing assembly 3 is arranged on the top side of the base 1. The polishing assembly 3 comprises a turntable 31 arranged in an annular shape, and the turntable 31 is rotatably sleeved on the top of the base 1 through a bearing, and a plurality of storage holes 310 are opened in a circular array on the top side of the turntable 31, and an outer ring 32 is rotatably mounted in the storage hole 310 through a rotating shaft 33, and the outer circumference of the outer ring 32 is The wall is arranged in an arc shape, a stopper 34 is arranged on the outer peripheral side of the rotating shaft 33, the outer peripheral wall of the outer ring 32 contacts the inner wall of the corresponding storage hole 310, an inner ring 35 is installed in the outer ring 32 through a bearing, and storage grooves 36 are provided at the positions corresponding to the front storage hole 310 and the right storage hole 310 on the top side of the base 1, a first motor 37 is fixedly installed in the storage groove 36, and the first motor 37 is connected to the inner ring 35 through a connecting mechanism 38, and a clamping mechanism 39 is provided in the inner ring 35; Two grinding mechanisms 5 are provided on the top side of the base 1 , a driving mechanism 4 is provided inside the turntable 31 , a turning mechanism 6 is provided on the outer peripheral side of the turntable 31 , and a flushing mechanism 7 is provided above the supporting leg 2 .

[0021] In this embodiment, when the improved spherical security camera lens polishing device is used, first, the driving mechanism 4 drives the turntable 31 located on the base 1 to rotate intermittently, and then the operator inserts the lens into the empty inner ring 35 in turn. Due to the clamping limit of the clamping mechanism 39, the lens is clamped and fixed in the inner ring 35, which enables the rotating turntable 31 to move the lens to the top of the first storage slot 36. At this time, the connecting mechanism 38 automatically completes the power connection between the first motor 37 and the inner ring 35, and enhances the clamping force of the clamping mechanism 39 on the lens, so that the position of the lens in the inner ring 35 remains stable. Then, the first motor 37 starts to drive the inner ring 35 to drive the lens to rotate continuously to cooperate with the first grinding mechanism 5 to complete the rough grinding operation on one side of the lens. Then, the turntable 31 moves the lens to the top side of the second storage slot 36. According to the above position, the first motor 37 drives the inner ring 35 to rotate to cooperate with the second grinding mechanism 5 to complete the fine grinding operation on one side of the lens, and the polishing operation on one side of the lens is completed; It should be noted that, when the fine grinding operation of the lens is being performed, the next lens is also synchronously moved to the top side of the first storage tank 36, and the rough grinding operation of the next lens is synchronously performed; After the polishing operation on one side of the lens is completed, the turntable 31 pushes the lens to the position of the flushing mechanism 7, so that the lens is flushed by water flow, and then the rotating turntable 31 cooperates with the flipping mechanism 6 to drive the outer ring 32 to rotate 180 degrees in the storage hole 310, so as to drive the lens to flip through the inner ring 35, and complete the polishing process of the other side of the lens in sequence according to the above, and when the lens moves to the position of the flushing mechanism 7, the impact force of the water flow on the lens pushes the lens out of the inner ring 35, and the unloading operation of the lens is automatically completed, without changing the equipment or repeatedly disassembling and installing the lens. One set of equipment can directly and continuously complete the rough grinding, fine grinding, flushing, flipping and unloading of the two sides of the lens, thereby improving the polishing efficiency of the lens and reducing the risk of damage to the lens. The device is simple to operate and has a high degree of automation. It should be noted that a control device is fixedly mounted on the front end of the outer peripheral wall of the base 1 to control the operating status of the device.

[0022] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 and Figure 6 As shown, the driving mechanism 4 includes a gear ring 41, and the gear ring 41 is fixedly installed in the inner hole of the rotating disk 31, a second motor 42 is fixedly installed on the top side of the base 1, a gear 43 is fixedly installed on the driving end of the second motor 42, and the gear 43 is meshed and connected with the gear ring 41; In this embodiment, when the driving mechanism 4 drives the rotating disk 31, the second motor 42 starts to drive the gear 43 to rotate, thereby driving the rotating disk 31 to rotate intermittently through the gear ring 41 to adjust the position of the storage hole 310 on the base 1. Since the diameter of the gear ring 41 is much larger than the diameter of the gear 43, the driving force of the second motor 42 on the rotating disk 31 can be greatly increased. It should be noted that the diameter of the gear ring 41 is much larger than the diameter of the gear 43 .

[0023] In a further preferred embodiment of the present invention, Figure 3 - Fig. 9 As shown, the limiting member 34 includes a plurality of spring pieces 343 in the shape of a hemispherical shell, two positioning grooves 341 in the shape of a quarter sphere are oppositely formed on the outer peripheral wall of the rotating shaft 33, and a placement groove 342 is formed at a position corresponding to the positioning groove 341 in the rotating disk 31, and the spring piece 343 is fixedly installed in the corresponding placement groove 342, and the spherical end of the spring piece 343 is inserted into the corresponding placement groove 342 and contacts the inner wall of the corresponding placement groove 342; In this embodiment, when the above-mentioned outer ring 32 rotates, due to the mutual interference between the spring piece 343 and the inner wall of the positioning groove 341, the spring piece 343 can be squeezed along the outer arc wall of the spring piece 343, so that the spring piece 343 shrinks and deforms and retracts into the placement groove 342, and the constrained positioning state of the rotating shaft 33 is automatically released. After the outer ring 32 flips 180 degrees, the spring piece 343 is just realigned with the positioning groove 341, and the spring piece 343 expands and deforms so that the spherical end of the spring piece 343 is reinserted into the positioning groove 341. At this time, due to the mutual interference between the spring piece 343 and the inner wall of the positioning groove 341, the constrained limiting state of the rotating shaft 33 is automatically restored, so that the outer ring 32 can stably maintain a straight state when not subjected to a large external force.

[0024] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the connection mechanism 38 includes a limit plate 381, which is fixedly mounted on the driving end corresponding to the first motor 37, and the limit plate 381 is rotatably connected to the inner wall of the corresponding storage groove 36 through a bearing, the top side of the limit plate 381 is coplanar with the top side of the base 1, and the top side of the limit plate 381 is provided with a plurality of limit grooves 382 in the shape of one-fifth of a sphere in a circumferential array, and the upper and lower ends of the inner ring 35 are provided with air storage grooves 383 at positions corresponding to the limit grooves 382, ​​and a piston push rod 384 is slidably mounted in the air storage groove 383, and a ball 385 is rotatably mounted in the piston push rod 384, and an end of the ball 385 close to the corresponding limit groove 382 is inserted into the corresponding limit groove 382 and contacts the inner wall of the corresponding limit groove 382; In this embodiment, as the turntable 31 rotates, when the inner ring 35 moves to the top side of the limit plate, the balls 385 are aligned with the limit grooves 382. At this time, due to the push of the piston by the gas in the gas storage tank 383, a small number of balls 385 are automatically inserted into the limit grooves 382. Moreover, due to the mutual interference between the balls 385 and the inner wall of the limit grooves 382, ​​the power connection between the limit plate and the inner ring 35 is automatically completed, and the operator does not need to perform other operations, which facilitates the use of the device. At the same time, since only a small part of the ball 385 is required, the inner ring 35 is automatically connected to the limit groove 382. The sub-ball 385 moves out of the air storage tank 383. As the piston push rod 384 pushes and compresses the gas in the air storage tank 383, the air pressure in the air storage tank 383 and the guide groove 392 is further increased, so that the friction between the clamping plate 391 and the lens is further increased, thereby further enhancing the friction between the clamping plate 391 and the lens, and finally further enhancing the clamping strength of the clamping plate 391 on the lens, so that when the grinding plate 53 is fitted with the lens, it will not cause the lens to be displaced and affect the grinding operation of the lens.

[0025] In a further preferred embodiment of the present invention, Figure 8 , Fig.10 and Fig.11 As shown, the clamping mechanism 39 includes a plurality of piston rods 393, a plurality of clamping plates 391 are slidably mounted in a circular array in the ring wall of the inner ring 35, and the opposite surfaces of the plurality of clamping plates 391 are coplanar with the inner arc wall of the corresponding inner ring 35, a guide groove 392 is provided in the ring wall of the inner ring 35 at the position corresponding to the clamping plate 391, the piston rod 393 is slidably mounted in the corresponding guide groove 392, and the driving end of the piston rod 393 is fixedly connected to the corresponding clamping plate 391, and the interior of the guide groove 392 is connected to the interior of the corresponding air storage tank 383 through a connecting hole 394; In this embodiment, during the rotation of the above-mentioned turntable 31, when the storage hole 310 moves to the top of the arc hole 63, the operator inserts one hand into the storage hole 310 from the top of the storage hole 310 and pushes the clamping plate 391 in all directions through the fingers to expand the spacing between the clamping plates 391. Then the operator holds the lens with the other hand and passes it through the arc hole 63, and inserts the lens into the inner ring 35 until the lens is connected to the limit block 78. Then the operator releases the push of the clamping plate 391. Due to the push of the piston rod 393 by the air inside the guide groove 392, the resistance between the clamping plate 391 and the outer peripheral wall of the lens increases, thereby generating a certain friction force between the lens and the clamping plate 391, so that the lens is clamped by the clamping plate 391 so that the lens is placed more stably in the inner ring 35. The loading operation of the lens is simple, and can also be replaced by manual operation by an externally arranged robot.

[0026] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Fig.14 As shown, the grinding mechanism 5 includes two electric telescopic rods 52, and two L-shaped support plates 51 are fixedly installed at the positions corresponding to the left end storage hole 310 and the front end storage hole 310 on the top side of the base 1 by bolts. The electric telescopic rod 52 is fixedly installed through the top of the corresponding support plate 51, and the driving rod of the electric telescopic rod 52 is slidably connected with the corresponding support plate 51. The driving end of the electric telescopic rod 52 is fixedly installed with a grinding plate 53, and the support plate 51 passes through the inner hole of the gear ring 41 and matches with the inner tooth gap of the gear ring 41; In this embodiment, when the lens moves to the top side of the limit plate, the first motor 37 drives the inner ring 35 to drive the lens to rotate continuously, and at the same time, the electric telescopic rod 52 is stretched to push the grinding plate 53 downward to move a corresponding distance according to the requirements of rough grinding of the lens, so that the grinding plate 53 is closely fitted with the lens. As the lens rotates, the grinding plate 53 slides in contact with the lens to complete the rough grinding operation or fine grinding operation of the lens; It should be noted that the bottom of the grinding plate 53 is made of soft grinding material, and the top of the grinding plate 53 is made of hard metal material.

[0027] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 5 As shown, the flip mechanism 6 includes a plurality of rollers 61, which are arranged in a circular array on the outer peripheral side of the turntable 31, and each roller 61 is fixedly connected to the corresponding rotating shaft 33, and a limiting strip 62 is provided at the bottom end of the rear roller 61, and the limiting strip 62 is fixedly connected to the outer peripheral wall of the base 1, and the limiting strip 62 contacts the outer peripheral wall of the corresponding roller 61, and both ends of the limiting strip 62 are arranged in an arc shape, and an arc hole 63 is opened at the bottom side of the base 1 at the position corresponding to the rear storage hole 310; In this embodiment, during the rotation of the above-mentioned turntable 31, when the lens moves to the position of the limit bar 62, the roller 61 moves gradually along the inclined surface of the limit bar 62 to the top side of the limit bar 62, and during the movement of the roller 61 at the top side of the limit bar 62, due to the friction between the roller 61 and the limit bar 62, as the turntable 31 rotates, the roller 61 drives the outer ring 32 to rotate. After the roller 61 is separated from the limit bar 62, the outer ring 32 drives the inner ring 35 and the lens to rotate 180 degrees. The automatic lens flipping operation does not require the operator to perform other operations, and the device has a high degree of automation.

[0028] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Fig.12 As shown, the flushing mechanism 7 includes a water storage tank 71, which is slidably installed between the base 1 and the support leg 2. A water pump 72 is fixedly installed on the outer peripheral wall of the base 1 at a position corresponding to the left end storage hole 310. A drainage pipe 73 is installed at the top of the water pump 72, and the drainage end of the drainage pipe 73 is located at the center position above the left end inner ring 35. A water inlet pipe 74 is fixedly installed through the bottom of the water storage tank 71, and the drainage end of the water inlet pipe 74 is connected and installed with the bottom end of the water pump 72. A filter plate 75 is fixedly installed in the water storage tank 71, and the filter plate 75 is located above the water inlet end of the water inlet pipe 74. In this embodiment, when the lens moves to above the circular hole 76, the water pump 72 is started, and the water at the bottom of the water tank 71 is continuously extracted through the water inlet pipe 74, and the extracted water is injected into the drain pipe 73. Then the water flows along the drain pipe 73 and is discharged from the center position above the lens. Then, due to the gravity of the discharged water itself, the water flow falls directly into the inner hole, and the lens flushing operation is completed by the water flow.

[0029] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, a circular hole 76 is provided at the bottom side of the base 1 at a position corresponding to the left end storage hole 310, and the diameter of the circular hole 76 is larger than the diameter of the outer ring 32, and a plurality of groups of drainage holes 77 are provided at the top side of the rotating disk 31, and each group of drainage holes 77 is provided in a circular array on the outer circumference side corresponding to the storage hole 310, and the interior of the drainage hole 77 is communicated with the interior of the corresponding storage hole 310, and the interior of the left end drainage hole 77 is communicated with the interior of the circular hole 76; In the present embodiment, when the lens is rinsed, part of the water flowing into the inner ring 35 passes through the gap between the lens and the inner ring 35 and flows into the circular hole 76, and the other part of the water overflows from the inner ring 35 and passes through the drainage hole 77 and flows into the circular hole 76. Subsequently, the water in the circular hole 76 passes through the circular hole 76 and falls into the water storage tank 71, and is sucked up by the water pump 72 for reuse. The impurities in the water are intercepted by the filter plate 75 and stored in the water storage tank 71, thereby reducing the water consumption when the device is in use.

[0030] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Figure 8 As shown, the bottom openings of the left and right inner rings 35, the bottom opening of the front inner ring 35, and the top opening of the rear inner ring 35 are all fixedly installed with limit blocks 78 in a circumferential array, and each limit block 78 is located between the corresponding two clamping plates 391, the water inlet end of the water inlet pipe 74 is located at the right end in the water storage tank 71, and a mesh plate 79 is provided above the filter plate 75, and the mesh plate 79 is fixedly connected to the inner wall of the water storage tank 71; In the present embodiment, during the polishing process of the lens, when the flipped lens moves to the position of the circular hole 76, the impact of the water flow on the center position of the lens may exert a downward thrust on the lens, and at this time, the flipped lens loses the restraint of the limit block 78, so that the lens automatically slides out of the inner ring 35 and passes through the circular hole 76 into the water tank. When the lens contacts the water in the water tank 71, due to the mutual conflict between the water flow and the lens and the push of the water flow on the lens, the lens slowly falls in the water in the water tank, and is finally intercepted by the mesh plate 79 and stored in the water tank 71. In the process of the lens falling, the water in the water tank 71 can directly complete the flushing of the entire outer wall of the lens, and the operator does not need to perform other operations to complete the unloading operation of the lens after polishing.

[0031] Working principle: When the improved spherical security camera lens polishing device is used, first, the second motor 42 starts the intermittent rotation of the driving gear 43, thereby driving the turntable 31 to rotate intermittently through the gear ring 41, and adjusting the position of the storage hole 310 on the base 1. When the storage hole 310 moves to the top of the arc hole 63, the operator inserts one hand from the top of the storage hole 310 into the storage hole 310 and pushes the clamping plate 391 in all directions through the fingers to expand the spacing between the clamping plates 391. Then, the operator holds the lens through the arc hole 63 with the other hand and inserts the lens into the inner ring 35 until the lens is connected to the limit block 78. Then, the operator releases the push of the clamping plate 391. Due to the push of the piston rod 393 by the air inside the guide groove 392, the resistance between the clamping plate 391 and the outer peripheral wall of the lens increases, thereby generating a certain friction between the lens and the clamping plate 391, so that the clamping of the lens by the clamping plate 391 makes the lens more stably placed in the inner ring 35; It should be noted that the lenses are installed and placed in the empty inner ring 35 in sequence according to the above; During the rotation of the above-mentioned turntable 31, when the outer ring 32 moves away from the top side of the circular hole 76 or the arc-shaped hole 63, the ball 385 can be squeezed into the air storage groove 383 due to the mutual interference between the ball 385 and the opening edge of the circular hole 76 or the arc-shaped hole 63, thereby automatically adjusting the position of the ball 385 so that the turntable 31 can rotate normally. After the lens is installed, when the lens moves to the position of the limit strip 62, the roller 61 moves gradually along the inclined surface of the limit strip 62 to the top side of the limit strip 62. During the movement of the roller 61 at the top side of the limit strip 62, due to the friction between the roller 61 and the limit strip 62, as the turntable 31 rotates, the roller 61 drives the outer ring 32 to rotate. After the roller 61 separates from the limit strip 62, the outer ring 32 drives the inner ring 35 and the lens to rotate 180 degrees, so as to perform the flipping operation of the lens. During the rotation of the roller 61, the rotating shaft 33 is synchronously driven to rotate. At this time, due to the mutual interference between the spring piece 343 and the inner wall of the positioning groove 341, the spring piece 343 can be squeezed along the outer arc wall of the spring piece 343, so that the spring piece 343 shrinks and deforms and retracts into the placement groove 342, and the restrained positioning state of the rotating shaft 33 is automatically released. After the outer ring 32 flips 180 degrees, the spring piece 343 is just realigned with the positioning groove 341, and the spring piece 343 expands and deforms so that the spherical end of the spring piece 343 is reinserted into the positioning groove 341. At this time, due to the mutual interference between the spring piece 343 and the inner wall of the positioning groove 341, the restrained limiting state of the rotating shaft 33 is automatically restored, so that the outer ring 32 can stably maintain a straight state when not subjected to a large external force; When the lens is moved to the right end storage hole 310, the inner ring 35 is just located above the limit plate, and the balls 385 are just aligned with the limit groove 382. At this time, due to the push of the piston by the gas in the gas storage groove 383, a small amount of balls 385 are automatically inserted into the limit groove 382, ​​and due to the mutual friction between the balls 385 and the inner wall of the limit groove 382, ​​the power connection between the limit plate and the inner ring 35 is automatically completed. At the same time, since most of the balls 385 cannot be moved out of the gas storage groove 383, the gas in the gas storage groove 383 is pushed and compressed by the piston push rod 384, and the air pressure in the gas storage groove 383 and the guide groove 392 is further increased, so that the friction between the clamping plate 391 and the lens is further increased, thereby further enhancing the friction between the clamping plate 391 and the lens, and finally further enhancing the clamping strength of the clamping plate 391 on the lens; After the power connection between the inner ring 35 and the limit plate is completed, the first motor 37 drives the limit plate to rotate. Due to the mutual interference between the ball 385 and the inner wall of the limit groove 382, ​​the rotating limit plate synchronously drives the inner ring 35 to rotate, and due to the mutual interference between the clamping plate 391 and the inner ring 35 and the friction between the clamping plate 391 and the lens, the rotating inner ring 35 synchronously drives the lens to rotate synchronously. While the lens rotates, the electric telescopic rod 52 stretches and pushes the grinding plate 53 downward to move a corresponding distance according to the requirement of rough grinding of the lens, so that the grinding plate 53 is closely fitted with the lens. As the lens rotates, the grinding plate 53 slides in contact with the lens to complete the rough grinding operation of the lens. It should be noted that when the inner ring 35 moves to the upper side of the limiting ring and the ball 385 is not aligned with the limiting groove 382, ​​as the first motor 37 drives the limiting plate to rotate, the limiting groove 382 will gradually move toward the ball 385, so that the ball 385 can gradually align with the ball 385; After the rough grinding of one side of the lens is completed, the second motor 42 drives the turntable 31 to rotate, so that the lens moves to the position of the front storage hole 310, so that the inner ring 35 moves to the next limit plate 381, and the power connection between the inner ring 35 and the next limit plate 381 is completed. The second motor 42 drives the gear 43 of the inner ring 35 to rotate, and then the front electric telescopic rod 52 pushes the front grinding plate 53 to fit the lens, so that the fine grinding operation of the lens is completed by the rotation of the lens. It should be noted that when the lens is being ground, polishing powder or polishing paste can be applied on the lens to assist the fine grinding operation of the lens; It should be noted that, when the fine grinding operation of the first lens is being performed, the next lens is also synchronously moved to the top side of the limit plate, and when the fine grinding operation of the first lens is being performed, the rough grinding operation of the next lens is synchronously performed; After the polishing operation on one side of the lens is completed, the lens moves to the top side of the circular hole 76 as the turntable 31 rotates. At this time, since the balls 385 are no longer restrained by external objects, most of the balls 385 are pushed out of the air storage tank 383. At this time, the air pressure in the guide groove 392 is restored, and the clamping strength of the lens is also restored. At the same time, the water pump 72 is started, and the water at the bottom of the water storage tank 71 can be continuously extracted through the water inlet pipe 74, and the extracted water is injected into the drain pipe 73. Then, the water flows along the drain pipe 73 and is discharged from the top of the lens. The water is discharged from the center position, and then due to the gravity of the discharged water, the water flows directly into the inner hole to wash the side of the lens that has completed the polishing operation. At the same time, part of the water flows through the gap between the lens and the inner ring 35 into the circular hole 76, and the other part of the water overflows from the inner ring 35 and flows through the drainage hole 77 into the circular hole 76. Then the water in the circular hole 76 passes through the circular hole 76 and falls into the water storage tank 71, and is sucked up by the water pump 72 for reuse, while the impurities in the water are intercepted by the filter plate 75 and are retained and stored in the water storage tank 71; It should be noted that, during the above-mentioned washing operation of the lens, due to the mutual interference between the lens and the stopper 78, the lens will not slip out of the inner ring 35; According to the lens that has been polished on one side as described above, when it moves to the position of the limit strip 62, the lens flipping operation is automatically completed, and then the lens moves to the bottom of the two grinding plates 53 in turn to complete the polishing of the other side of the lens. When the lens that has completed the polishing on both sides moves to the top side of the circular hole 76 again, the water flow impacts the center position of the lens, which can exert a downward thrust on the lens, and at this time, the lens loses the restraint of the limit block 78 due to the flipping, so that the lens automatically slides out of the inner ring 35 and passes through the circular hole 76 and falls into the water tank. When the lens contacts the water in the water tank 71, due to the mutual conflict between the water flow and the lens and the push of the water flow on the lens, the lens slowly falls in the water in the water tank, and is finally intercepted by the mesh plate 79 and stored in the water tank 71. In the process of the lens falling, the water in the water tank 71 can directly complete the flushing of the entire outer wall of the lens. It should be noted that, when the lens is polished, the outer ring 32 of the lens cannot be polished due to the influence of the stopper 78. It should be noted that when the lens is used, the outer ring 32 of the lens is the covering installation position of the sealing strip or the external bracket, which will not affect the normal use of the camera lens. As described above, with the rotation of the turntable 31, the rough grinding, fine grinding, washing, flipping and unloading operations of a large number of lenses can be automatically completed in sequence. After the lens storage amount in the water tank 71 reaches the set amount, the operator stops the operation of the device, and then the operator unscrews the water inlet pipe 74 from the bottom end of the water pump 72 to complete the disassembly between the water pump 72 and the water inlet pipe 74. At this time, the operator can directly remove the water tank 71 from the support leg 2 by sliding the water tank 71 with the base 1 and the support leg 2. The lens can be moved to the corresponding position by moving the water tank 71, and then the lens can be taken out of the water tank 71 through the top opening of the water tank 71 to perform lens inspection. After completing the disassembly of the water tank 71, replace the new water tank 71 and insert it between the base 1 and the support leg 2, and then reconnect the water inlet pipe 74 with the water pump 72, so that the device can be restored to use.
