Description

Technical Field

[0001] This utility model relates to the field of edge grinding equipment technology, and in particular to an optical lens edge grinding equipment. Background Technology

[0002] Optical lenses are core components of optical systems, primarily used for refracting, reflecting, or modulating light. They are widely used in eyeglasses, cameras, microscopes, telescopes, laser equipment, and other fields. During the processing of optical lenses, edging equipment is required to grind the lenses to eliminate burrs and chipping, and reduce stray light. However, current edging equipment requires workers to unload the lens after it has been ground and then replace it with another lens to be ground, resulting in long downtimes and reduced edging efficiency. Utility Model Content

[0003] This utility model discloses an optical lens edging device, which solves the problem that after the lens edging is completed, workers need to unload the lens and then replace it with a lens to be edged, which requires a long downtime and reduces the efficiency of lens edging.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An optical lens edging device includes a worktable and a workpiece. The worktable has two rotatable turntables for supporting the workpiece, and a grinding strip that can move towards the two turntables is provided between the two turntables. A top plate is provided above the worktable, and a connecting plate is fixed on the top plate. A motor is fixed on the connecting plate, and a lead screw is fixed on the shaft of the motor. A vertical plate that is threaded to the lead screw and fixed to the grinding strip is slidably connected to the connecting plate. A liftable pressure plate is provided above the turntables, and a ring is rotatably connected to the bottom of the pressure plate.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After a workpiece is placed on a turntable, the pressure plate corresponding to the turntable moves the ring downwards, pressing the top of the workpiece down. Then, the first motor is started, causing the first lead screw to rotate and drive the grinding strip towards the turntable where the workpiece is placed, bringing the grinding strip into contact with the edge of the workpiece. The turntable then rotates, causing the workpiece and the ring to rotate together, and the grinding strip begins to grind the edge of the workpiece. Simultaneously, the operator can place another lens to be processed on another turntable, and the other ring moves downwards to press and fix the lens. After the previous lens is ground, the first lead screw can be rotated, moving the grinding strip towards the lens to be ground, and grinding begins. The operator can then remove the ground lens and replace it with the next lens. This invention allows the operator to start grinding the next lens while the ground lens is being unloaded, eliminating the need for long downtime for unloading and loading lenses, thus improving the efficiency of lens grinding.

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 and Figure 4As shown, this utility model provides an optical lens edging device, including a worktable 1 and a workpiece 10. The worktable 1 is provided with two rotatable turntables 2 for supporting the workpiece 10. A grinding strip 4 that can move towards the two turntables 2 is provided between the two turntables 2. A top plate 5 is provided above the worktable 1. A connecting plate 7 is fixed on the top plate 5. A first motor 71 is fixed on the connecting plate 7. A first lead screw 72 is fixed on the shaft of the first motor 71. A vertical plate 73 that is slidably connected to the connecting plate 7, threadedly connected to the first lead screw 72, and fixed to the grinding strip 4 is fixed to the first lead screw 72. A liftable pressure plate 6 is provided above the turntables 2. A ring 61 is rotatably connected to the bottom of the pressure plate 6. Workpiece 10 is a lens to be edge-ground. The grinding strip 4 can be made of diamond, silicon carbide, or alumina, depending on the material of the lens and the actual situation. First, workpiece 10 is placed on top of a turntable 2. Then, the pressure plate 6 corresponding to the turntable 2 is moved downward, so that the bottom of the ring 61 presses down on the top of workpiece 10, thus fixing workpiece 10. Next, motor 71 is started to rotate the lead screw 72, so that the vertical plate 73 moves toward the turntable 2 on which workpiece 10 is placed. The grinding strip 4 then contacts the edge of workpiece 10 as the vertical plate 73 moves. Finally, the turntable 2 on which workpiece 10 is placed is rotated, which can drive workpiece 10 and ring 61. 1. The machine rotates, and the grinding strip 4 begins to grind the edge of the workpiece 10. During the grinding process, the operator can place the workpiece 10 to be ground on another turntable 2. After the previous workpiece 10 has been ground, the first motor 71 can be started to make the first lead screw 72 continue to rotate, so that the vertical plate 73 drives the grinding strip 4 to move towards the workpiece 10 to be ground. When the workpiece 10 is to be ground again, the previously ground workpiece 10 can be removed and replaced with another workpiece 10 to be ground. The above operation is repeated. There is no need for the operator to stop the machine for a long time to load and unload the workpiece 10, which improves the processing efficiency of the workpiece 10.

[0015] like Figure 1 As shown, a support frame 3 is fixed to the bottom of the workbench 1. Two secondary motors 31 are fixed on the support frame 3. Rotating rods are fixed to the shafts of the secondary motors 31. The two rotating rods are fixed to the center of the bottom of the two turntables 2 respectively. A rubber pad 21 is fixed to the top of the turntable 2. After the secondary motors 31 are started, the turntables 2 can be rotated through the rotating rods. The top of the rotating rods penetrates the bottom of the workbench 1. When the workpiece 10 is placed on the turntable 2 and comes into contact with the rubber pad 21, the friction between the turntable 2 and the workpiece 10 is increased, further increasing the stability of the workpiece 10 placed on the turntable 2.

[0016] like Figure 1As shown, two No. 3 motors 51 are fixed on the top plate 5. A No. 2 lead screw 52 is fixed on the shaft of the No. 3 motor 51. A moving block 53 is slidably connected to the top plate 5 and threadedly connected to the No. 2 lead screw 52. A No. 1 electric telescopic rod 54 is fixed on the moving block 53. A connecting frame 55 is fixed to the telescopic end of the No. 1 electric telescopic rod 54. The two connecting frames 55 are respectively fixed to the two pressure plates 6. Motor 71, Motor 31, and Motor 51 are all servo motors. After starting Motor 51, the No. 2 lead screw 52 can be rotated. The moving block 53 can then drive the connecting frame 55 to move via the No. 1 electric telescopic rod 54. The pressure plate 6 can move with the connecting frame 55 to adjust the position of the ring 61 according to different types of workpieces 10. Subsequently, starting the No. 1 electric telescopic rod 54 will move the pressure plate 6 downward, allowing the ring 61 to better press and fix the workpiece 10 as it descends. The connecting plate 7 is T-shaped, with the two No. 2 lead screws 52 rotatably connected to the connecting plate 7 at their closest points. A support plate is fixed between the top plate 5 and the worktable 1.

[0017] like Figure 1 and Figure 4As shown, a second electric telescopic rod 8 is fixed on the connecting frame 55. The telescopic end of the second electric telescopic rod 8 is fixed with a connecting pipe 81 through a fixing plate. The bottom end of the connecting pipe 81 passes through the pressure plate 6 and is connected to a suction cup 82 located inside the ring 61. When it is necessary to unload the workpiece 10 after edge grinding, the first electric telescopic rod 54 can be activated to move the pressure plate 6 upward, so that the ring 61 no longer presses down on the workpiece 10. Then, the first electric telescopic rod 54 is closed, and the telescopic end of the second electric telescopic rod 8 extends downward, so that the connecting pipe 81 drives the suction cup 82 to move below the ring 61 (the connecting pipe 81 is connected to the external air pump through an external hose). When the suction surface of the suction cup 82 contacts the workpiece 10 and generates suction, the workpiece 10 can be sucked up. Then, the corresponding third motor 51 is activated, so that the suction cup 82 moves the workpiece 10 away from the top of the turntable 2, completing the unloading of the workpiece 10. Two external collection boxes for collecting edge-ground workpieces 10 can be placed on the worktable 1, with the two turntables 2 positioned between the two external collection boxes. Alternatively, two external placement boxes containing workpieces 10 to be edge-ground can be placed on the worktable 1, with the two external collection boxes positioned between the two external collection boxes. Between two external placement boxes; after the workpiece 10 is edge-ground, the edge-ground workpiece 10 can be picked up by the corresponding suction cup 82 and placed in a corresponding external collection box. Then the suction cup 82 can continue to move, picking up the workpiece 10 in the corresponding external placement box for automatic loading. Through the cooperation of motor 51, electric telescopic rod 54, electric telescopic rod 8 and suction cup 82, the automatic loading and unloading of workpiece 10 can be completed. Motor 71, motor 31, motor 51, electric telescopic rod 54 and electric telescopic rod 8 are all controlled by an external control panel. The control program of the external control panel can be set by the operator according to the actual situation. The setting of the control program is a very mature existing technology and will not be described in detail here. Electric telescopic rod 54 can also be an anti-torque electric telescopic rod.

[0018] like Figure 1 and Figure 3 As shown, two connecting blocks 9 are fixed on the vertical plate 73 above the grinding strip 4. Each connecting block 9 is fixed with a delivery pipe 91 for conveying coolant. The drain ends of the two delivery pipes 91 correspond to the two sides of the grinding strip 4. The delivery pipes 91 are connected to an external coolant storage cylinder. During the grinding process of the grinding strip 4 on the workpiece 10, the delivery pipes 91 can discharge coolant through the drain ends to cool the grinding strip 4.

[0019] like Figure 1As shown, a collection cylinder 32 is fixed on the support frame 3. A slot 11 is opened on the top of the workbench 1 between the two turntables 2. The bottom of the slot 11 is connected to a drain pipe that passes through the top of the collection cylinder 32. The coolant and the debris generated during the grinding process of the workpiece 10 can flow into the slot 11 together and then be discharged into the collection cylinder 32 through the drain pipe. Finally, it is discharged through the discharge end on the collection cylinder 32 (the discharge end is not shown in the figure).

[0020] like Figure 1 and Figure 4 As shown, a rubber ring 62 is fixed to the bottom of the ring 61. After the ring 61 moves downward and the rubber ring 62 comes into contact with the top of the workpiece 10, the friction between the ring 61 and the workpiece 10 is increased, thereby increasing the stability of the ring 61 in pressing and fixing the workpiece 10.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
