Description

Technical Field

[0001] The present invention relates to the technical field of lens edging, and in particular to a camera lens edging system based on a centering cooling structure. Background Art

[0002] A camera lens is the device that captures the image of the scene on the sensor and is typically composed of several lenses. Based on their material, camera lenses can be categorized as either plastic or glass. Edging camera lenses is a critical step in optical lens processing, directly impacting their image quality, assembly accuracy, and durability.

[0003] The camera lens is generally cut into a circular lens first, and then the edge of the circular lens is polished using a lens edger. During edging, the lens is clamped by symmetrically distributed electric rotating suction cups, and then the clamped lens is placed close to the electric grinding wheel for edging. The above-mentioned lens edger has the following shortcomings during use: 1. When clamping the lens, the worker generally manually places the lens between the two suction cups. The axis of the lens and the suction cup is easily misaligned, resulting in unequal distances between the edge of the lens and the suction cup after the suction cup clamps the lens. When the grinding wheel polishes the edge of the lens, it will first contact and polish the more protruding part. Only after the protruding part is polished off can the edge of the lens be polished, affecting the efficiency of lens polishing; 2. During the process of polishing the lens, water is generally sprayed on the lens for cooling. However, since the lens is clamped by the suction cup, the lens inside the suction cup is difficult to contact the cooling water, resulting in the temperature of the part of the lens inside the suction cup rising, affecting the quality of the lens. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a camera lens edging system based on a centering cooling structure, comprising a workbench, on the top of which a centering loading mechanism, a centering cooling mechanism and an edging mechanism are sequentially installed from front to back.

[0012] In one possible implementation, the unloading component includes a push-down plate that is slidably installed inside the cache chamber.

During the process of rotating the lens driven by the electric rotating rod, when the edge of the lens rotates to the electric grinding wheel for edge grinding, the corresponding wedge block and the pushing plate interfere with each other, causing the water spray hole to open and spray water to cool the contact area between the lens and the electric grinding wheel. When the water spray hole is away from the electric grinding wheel, the wedge block and the pushing plate separate to close the water spray hole, preventing the water spray hole from spraying water to other parts and affecting the worker's operation.

However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The centering feeding mechanism 2 includes a support frame 21 fixedly installed on the top of the workbench 1, a movable frame 22 is rotatably installed at the bottom of the support frame 21, and the front and rear ends of the movable frame 22 are fixedly connected with a support ring 221, and a plurality of circumferentially uniformly distributed rubber rollers 23 are slidably installed on the top of the support ring 221 along its radial direction. A rotating feed assembly 24 is installed on the support frame 21 for driving the movable frame 22 to rotate back and forth and driving the rubber roller 23 to move toward the center direction of the support ring 221 during the rotation of the movable frame 22.

[0034] See also Figure 1 、 Figure 9 and Figure 10 The centering cooling mechanism 3 includes symmetrically distributed electric rotating rods 32 in the upper and lower parts, and an opposing moving assembly 31 that drives the two electric rotating rods 32 to move toward each other. Rubber discs 33 are fixedly connected to opposite sides of the upper and lower electric rotating rods 32. Cooling grooves 34 are formed on opposite sides of the upper and lower rubber discs 33. The rubber discs 33 are provided with water spray holes 35 evenly distributed around the circumference and connected to the cooling grooves 34. A plurality of suction cups 37 are mounted on the rubber discs 33 in the circumference. It should be noted that the opposing moving assembly 31 is a prior art. The opposing moving assembly 31 is a bidirectional electric translation stage that drives the upper and lower opposing moving assemblies 31 to move synchronously in opposite directions. The electric rotating rods 32 are rotatably connected to the corresponding cross frame on the opposing moving assembly 31. The lower cross frame is also equipped with a rotary motor that drives the corresponding electric rotating rod 32 to rotate.

[0035] See also Figure 3 - Figure 5 The rotary feed assembly 24 includes a drive motor 241 fixedly mounted on the top of the support frame 21, a transmission rack 244 is installed on the bottom of the support frame 21 for sliding left and right, a transmission gear 245 is coaxially fixedly connected to the top of the movable frame 22, the transmission rack 244 is meshed with the transmission gear 245, and a reciprocating component 242 is installed at the bottom of the support frame 21 for driving the transmission rack 244 to move left and right. The bottom end of the output shaft of the drive motor 241 passes through the bottom of the support frame 21 and is connected to the reciprocating component 242 through a gear set 243 installed at the bottom of the support frame 21.

[0036] See also Figure 2 - Figure 3The rotary feed assembly 24 also includes a fixed gear 246 rotatably mounted inside the movable frame 22. The fixed gear 246 is fixedly connected to the support frame 21 through a shaft. The movable frame 22 is rotatably connected to the shaft. A passive gear 247 is rotatably mounted inside the support ring 221. The front and rear passive gears 247 are both engaged with the fixed gear 246. The passive gear 247 is provided with a number of arc grooves 248 evenly distributed circumferentially. The bottom end of the rubber roller 23 is movably mounted in the corresponding arc groove 248.

[0037] See also Figure 4 - Figure 5 The reciprocating component 242 includes a turntable 2421 rotatably mounted on the bottom of the support frame 21, and a round rod 2422 that does not coincide with its axis is rotatably mounted on the bottom of the turntable 2421. The transmission rack 244 is fixedly connected to a groove frame 2423 at one end close to the turntable 2421, and the round rod 2422 is slidably mounted inside the groove frame 2423. The output shaft of the drive motor 241 is connected to the turntable 2421 through a gear set 243, and the transmission ratio of the gear set 243 is 2:1.

[0038] See also Figure 1 - Figure 5 When in use, the lens is placed on the support ring 221 on the front side, and the output shaft of the driving motor 241 drives the turntable 2421 to rotate intermittently through the gear set 1 243. When the output shaft of the driving motor 241 rotates one circle, the turntable 2421 rotates half a circle, and the turntable 2421 drives the round rod 2422 to rotate, and the round rod 2422 is used to drive the groove frame 2423 to move back and forth left and right. In the process of the groove frame 2423 moving left and right, the round rod 2422 slides back and forth along the groove frame 2423, and the groove frame 2423 drives the transmission rack 244 to move left and right, and the transmission rack 244 drives the transmission gear 245 to rotate back and forth, so that the movable frame 22 rotates 180 degrees alternately in the forward and reverse directions, so that the support ring 221 moves the lens from front to back between the upper and lower electric rotating rods 32.

[0039] During the process of the support ring 221 rotating from front to back, the passive gear 247 rotates around the fixed gear 246, and the fixed gear 246 drives the passive gear 247 to rotate. The arc groove 248 on the passive gear 247 guides the rubber roller 23 to slide toward the center of the support ring 221, so that the rubber roller 23 centers the lens on the support ring 221. When the electric rotating rod 32 clamps the lens in the center, the distance that the lens is exposed to the outside of the rubber disk 33 is equal, which is conducive to uniform circumferential grinding of the lens and improves the efficiency of lens grinding.

[0040] When the support ring 221 rotates from back to front, the driven gear 247 rotates in the opposite direction around the fixed gear 246, so that the fixed gear 246 drives the driven gear 247 to rotate in the opposite direction. At this time, the arc groove 248 guides the rubber roller 23 to slide away from the center of the support ring 221, so that the rubber roller 23 moves and resets, making it easier for subsequent lenses to fall onto the support ring 221.

[0041] The lens is clamped by the rubber roller 23 , and the rubber has a certain elasticity and buffering effect, which prevents the lens from being damaged by the clamping, and at the same time facilitates the rubber disk 33 below to push the lens upward from the support ring 221 .

[0042] When the movable frame 22 rotates alternately forward and reverse, the two support rings 221 can alternately load the lenses. When one support ring 221 is conveying the lenses for edging, the lenses can be placed on the other support ring 221, thereby improving the efficiency of lens loading and thus improving the efficiency of lens edging.

[0043] See also Figure 2 、 Figure 6 、 Figure 7 and Figure 8 , and also includes a loading component 25, which includes a storage barrel 251 fixedly connected to the top of the workbench 1 and located on the front side of the support frame 21, the storage barrel 251 is a hollow barrel with an open top, and a cache chamber 252 is installed on the rear side of the bottom end of the storage barrel 251, and the bottom end of the storage barrel 251 is connected to the cache chamber 252 front and back, and a loading component 253 for pushing the lens to move backward is installed on the storage barrel 251, and a unloading component 254 for pushing the lens to move downward is installed on the top of the cache chamber 252, and a support component 255 for supporting the lens is installed at the opening at the bottom of the cache chamber 252, the front end support ring 221 is located directly below the cache chamber 252, and the rear end support ring 221 is located between the upper and lower electric rotating rods 32.

[0044] See also Figure 4 - Figure 7 The loading component 253 includes a loading plate 2531 that is slidably installed on the storage barrel 251. A through hole for accommodating the lens is opened inside the loading plate 2531. A reciprocating component 2532 for driving the loading plate 2531 to move back and forth is installed on the support frame 21. The structure of the reciprocating component 2532 is the same as that of the reciprocating component 1 242. The output shaft of the drive motor 241 is connected to the reciprocating component 2532 through a gear set 2533 installed on the support frame 21. The transmission ratio of the gear set 2533 is 1:1.

[0045] See also Figure 6 - Figure 8The unloading component 254 includes a lower push plate 2541 that is installed in the buffer chamber 252 for sliding up and down. The top of the lower push plate 2541 is coaxially fixedly connected with a synchronization plate 2542 located above the buffer chamber 252. The rear end of the synchronization plate 2542 is fixedly connected with a guide rod 2543. The top of the support frame 21 is rotatably installed with a guide wheel 2544. The guide wheel 2544 is coaxially fixedly connected with the turntable 2421 in the reciprocating component 2532. An elliptical guide inclined groove is provided on the guide wheel 2544, and the guide rod 2543 is slidably installed in the guide inclined groove.

[0046] See also Figure 6 and Figure 8 The loading assembly 25 includes a plurality of support plates 2551 hinged at the bottom of the buffer chamber 252 and evenly distributed circumferentially. A torsion spring 2552 for driving the support plate 2551 to rotate upward is installed on the hinge shaft of the support plate 2551.

[0047] See also Figure 2 、 Figure 6 、 Figure 7 and Figure 8 During specific use, the lenses that need to be edged are stacked in the storage barrel 251, and the loading plate 2531 is supported on the bottom of the lenses. When loading, the driving motor 241 drives the reciprocating component 2532 through the gear set 2533, and then the reciprocating component 2532 drives the loading plate 2531 to move back and forth to transport the lenses in the storage barrel 251 backward to the buffer chamber 252; the loading plate 2531 moves forward first, and the through hole on the loading plate 2531 moves to the bottom of the lenses in the storage barrel 251, so that one of the lenses in the storage barrel 251 falls into the through hole, and then the loading plate 2531 moves backward, so that the through hole pushes the lens forward into the buffer chamber 252. At this time, the support plate 2551 is supported on the bottom of the lens to prevent the lens from falling from the bottom of the buffer chamber 252.

[0048] During the rotation of the movable frame 22, the driving motor 241 drives the guide wheel 2544 to rotate through the gear set 2533. The guide inclined groove on the guide wheel 2544 guides the guide rod 2543 to move back and forth. The guide rod 2543 drives the synchronization plate 2542 and the push-down plate 2541 to move back and forth. When the support ring 221 rotates to the bottom of the buffer chamber 252, the push-down plate 2541 just moves downward, pushing the lens in the buffer chamber 252 downward. When the push-down plate 2541 pushes the lens downward, the support plate 2551 flips downward, causing the lens to fall onto the support ring 221.

[0049] When the support ring 221 rotates away from the bottom of the cache chamber 252, the guide wheel 2544 guides the guide rod 2543 and the synchronization plate 2542 to move upward, and then the synchronization plate 2542 drives the push-down plate 2541 to move upward and reset. When the push-down plate 2541 moves upward, the support plate 2551 is driven by the torsion spring 2552 to flip upward to a horizontal state, so as to facilitate supporting subsequent lenses.

[0050] See also Figure 1 、 Figure 10 The rubber disc 33 is provided with several water diversion grooves 341 that are connected to the cooling groove 34 and are evenly distributed around the circumference. The ends of the water diversion grooves 341 close to the center of the rubber disc 33 are connected to each other. The interior of the water diversion grooves 341 is fixedly connected with several arc-shaped tiles 342 that are alternately distributed. A water inlet ring 343 is rotatably installed on the electric rotating rod 32. The end of the water diversion grooves 341 close to the center of the rubber disc 33 is connected to the water inlet ring 343 through a pipe located inside the electric rotating rod 32.

[0051] See also Figure 1 、 Figure 9 and Figure 10 During specific use, after the support ring 221 transports the lens to between the upper and lower electric rotating rods 32, the movable frame 22 stops rotating. At this time, the upper and lower electric rotating rods 32 are driven to move synchronously toward each other through the opposite moving component 31. The lower rubber disk 33 first contacts the lens and pushes the lens on the support ring 221 to move upward, so that the lens moves to the top of the rubber roller 23 until the upper and lower rubber disks 33 clamp the lens in the center up and down to prevent the rubber roller 23 from affecting the edging of the lens. Then the electric rotating rod 32 and the rubber disk 33 drive the lens to rotate together.

[0052] After the rubber disc 33 clamps the lens, the suction cup 37 absorbs the lens to improve the stability of the rubber disc 33 clamping the lens and prevent the lens from falling off during rotation; cooling water is transported to the water inlet ring 343 through the existing water supply equipment, and during the rotation of the electric rotating rod 32, the water inlet ring 343 transports cooling water to the water diversion groove 341 through the pipeline in the electric rotating rod 32, and then the water diversion groove 341 transports the cooling water to the cooling groove 34, and the cooling water in the cooling groove 34 and the water diversion groove 341 is used to cool the lens located on the inner side of the rubber disc 33. At the same time, the cooling water in the cooling groove 34 flows out from the water spray hole 35 to cool the lens leaking out of the rubber disc 33, thereby improving the cooling effect of the lens.

[0053] By arranging the curved tiles 342 inside the water diversion groove 341, when the cooling water flows from the water diversion groove 341 to the cooling groove 34, the alternatingly distributed curved tiles 342 can slow down the flow of the cooling water, thereby preventing the cooling water in the water diversion groove 341 from flowing too fast during the rotation of the rubber disc 33, resulting in excessive impact force on the edge of the rubber disc 33, causing deformation, and affecting the fit between the edge of the cooling groove 34 and the lens.

[0054] See also Figure 10 、 Figure 11 and Figure 12 A sealing assembly 36 for sealing the water spray hole 35 is also installed inside the water spray hole 35. The sealing assembly 36 includes a sealing block 361 that is slidably installed along the radial direction of the rubber disc 33. The end of the sealing block 361 away from the center of the rubber disc 33 is fixedly connected to a wedge block 362 located on the outside of the rubber disc 33 through a short rod. A compression spring 363 mounted on the outside of the short rod is fixedly connected between the wedge block 362 and the inner wall of the water spray hole 35.

[0055] See also Figure 1 、 Figure 12 The edging mechanism 4 includes a movable seat 41 that is slidably mounted on the top of the workbench 1 and is located on the rear side of the opposing movable component 31. A servo electric cylinder 42 is also installed on the top of the workbench 1 to push the movable seat 41 to move back and forth. An electric grinding wheel for grinding the edge of the lens is installed on the movable seat 41. A pushing plate 43 that is symmetrical up and down and used to push the wedge block 362 is fixedly installed on the front side of the movable seat 41.

[0056] See also Figure 1 、 Figure 10 、 Figure 11 and Figure 12 When the wedge block 362 rotates to separate from the pushing plate 43, the rebound force of the compression spring 363 pushes the wedge block 362 to move away from the center of the rubber disc 33, so that the blocking block 361 blocks the corresponding water spray hole 35 again. By selectively opening the water spray hole 35, only the part of the lens being polished is cooled, which reduces the use of cooling water and prevents the water spray hole 35 from spraying water to other parts and affecting the worker's operation.

[0057] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, integral or sliding connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
