Description

Technical Field

[0001] This invention relates to the field of optical lens processing, and more particularly to an optical lens processing apparatus. Background Technology

[0002] Optical lens bonding is a crucial process in optical manufacturing, involving the precise bonding and curing of two or more lenses to achieve specific optical properties. Currently, the loading of the upper lens in the lens bonding process is mostly done manually, with operators holding the lens or using simple clamps to transfer it to the bonding station. This method has several drawbacks:

[0003] Firstly, manual feeding is inefficient and difficult to match the cycle time requirements of automated gluing production lines, resulting in limited overall production efficiency.

[0004] Secondly, the positional accuracy of manually placed lenses is difficult to guarantee, and positioning deviations are prone to occur, causing the optical center of the glued lenses to shift, thus reducing the product qualification rate.

[0005] Third, repetitive manual feeding actions over a long period of time can easily cause operator fatigue, increase the risk of operational errors, and pose certain safety hazards.

[0006] These problems collectively restrict the automation level and product qualification rate of the optical lens bonding process. Therefore, it is urgent to develop an optical lens processing equipment to overcome the above-mentioned defects. Summary of the Invention

[0007] The technical solution is as follows: An optical lens processing equipment includes a worktable, a storage tray on the top of the worktable, a clamp on the storage tray, the clamp being electrically controlled, a feeding rack fixedly connected to the upper side of the worktable, symmetrically arranged rodless cylinders fixedly connected to the top of the worktable, a receiving rack slidably connected between the rodless cylinders, a blocking mechanism on the feeding rack, and a material transfer mechanism on the receiving rack.

[0008] Preferably, the material transfer mechanism includes a conveying component, which is symmetrically arranged and installed on the loading rack. The conveyor belt on the conveying component is fixedly connected with first rubber blocks distributed at equal intervals, and the conveying component is controlled by a power source.

[0009] Preferably, the blocking mechanism includes a movable block that is symmetrically and slidably connected to the receiving frame, a second rubber block that is fixedly connected to the movable block on the side close to each other, the second rubber block being used to support the upper lens, and a first spring connecting the movable block on the side far from each other and the receiving frame.

[0010] Preferably, it also includes a sliding block, which is slidably connected between the rodless cylinders. The sliding block and the receiving frame are fixedly connected. A glue storage cylinder for storing glue is provided in the middle of the sliding block. A glue outlet is connected to the bottom of the glue storage cylinder. A conical block is slidably connected inside the glue outlet. A second spring is connected between the upper part of the conical block and the glue outlet.

[0011] Preferably, it also includes a push-pull rod, which is fixedly connected to the bottom of the cone-shaped block. Symmetrically arranged rotating columns are rotatably connected to the push-pull rod, and the rotating columns and the storage tray are in a pressing fit.

[0012] Preferably, the device also includes a rack and pinion frame, which is slidably connected to the side of the worktable near the loading rack. Symmetrically arranged one-way gears are fixedly connected to the side of the conveying component away from the storage tray, and the one-way gears mesh with the rack and pinion frame.

[0013] Preferably, the device also includes a support frame, with the support frame positioned between the tops of the rodless cylinders. An electric push rod is fixedly connected to the middle of the support frame, and a lifting frame is fixedly connected to the bottom of the telescopic rod of the electric push rod. The lifting frame and the support frame are slidably connected.

[0014] Preferably, a servo motor is also included. The servo motor is located in the middle of the lifting frame. The output shaft of the servo motor is fixedly connected to the bend rod. A swing ball is set at the bottom of the bend rod. The swing ball is rotatably connected to the lower part of the lifting frame. A swing disk is fixedly connected to the swing ball. A rubber column is slidably connected to the lower part of the lifting frame along the circumferential direction. The top of the rubber column and the swing disk are pressed together. A third spring is connected between the rubber column and the lifting frame.

[0015] Preferably, it also includes a rubber stopper, which is fixedly connected to the middle of the bottom of the lifting frame.

[0016] Preferably, it also includes wedge blocks, which are respectively connected to the lifting frame, and columns are provided on both sides of the moving block, with the columns and wedge blocks engaging in a pressing fit.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention uses a stacked loading rack to store the upper lens, and uses a rodless cylinder, receiving rack and blocking mechanism to complete the automatic loading, replacing the manual hand-held transfer mode. This not only solves the efficiency bottleneck of manual loading, but also reduces the fatigue of operators, while ensuring the transfer accuracy of the upper lens and avoiding positioning deviation caused by manual operation.

[0018] 2. This invention uses the linkage of the lifting action of the glue storage cylinder, the cone-shaped block and the storage tray, and the mechanical cooperation of the push-pull rod and the rotating column to automatically complete the glue dispensing and cutting off, eliminating the need for manual glue dripping. This not only simplifies the operation steps, but also ensures the accuracy of glue landing point, improves the uniformity of glue layer distribution, and avoids the errors in dosage and position of manual glue dripping.

[0019] 3. This invention utilizes an electric push rod and a servo motor to drive a rocking disk and a rubber column, simulating manual pressing and shaking motions to achieve automatic pressing and shaking of the upper lens circumference. This efficiently removes air bubbles from the adhesive layer and ensures uniform adhesive layer thickness. At the same time, a rubber abutment is used to fix the center of the lens, preventing the lens from shifting during the pressing process and improving the stability of the optical performance after bonding.

[0020] 4. This invention uses a single cylinder to control the lifting and lowering of the tray, the movement of the rack and pinion, and the rotation of the one-way gear, simultaneously completing the actions of lower lens positioning, automatic glue dispensing, and upper lens feeding. During the descent of the lifting frame, the linkage wedge block realizes the automatic material release mechanism. Each process does not require an additional power source to drive it, reducing the complexity of equipment control and lowering production and maintenance costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] An optical lens processing device, such as Figure 1As shown, a tray 2 is installed on the top of the workbench 1, and a clamp 3 is installed on the tray 2. The clamp 3 is electrically controlled. After the lower lens 4 is placed on the tray 2, the clamp 3 is electrically controlled to lower the lens 4. The lower lens 4 is a concave lens. Then, glue is dripped onto the bottom of the lower lens 4. According to the background art, currently, the loading of the upper lens 6 in the lens bonding process is mostly done manually. The operator holds the lens or uses a simple clamp 3 to transfer the upper lens 6 to the bonding station. This has the problems of limited production efficiency, difficulty in ensuring accuracy, and easy fatigue of the operator due to the loading action. Therefore, this embodiment proposes the following solution:

[0029] like Figure 1 As shown, a feeding rack 5 is fixedly connected to the upper side of the workbench 1. The feeding rack 5 is used to store the upper lens 6. The upper lens 6 is a convex lens. The upper lenses 6 are stacked and stored. The upper lenses 6 can be pre-stored on the feeding rack 5. During the process of bonding optical lenses, the feeding can be continuous without manual feeding.

[0030] The top of the workbench 1 is fixedly connected with symmetrically arranged rodless cylinders 7. A receiving frame 8 is slidably connected between the rodless cylinders 7. A blocking mechanism is set on the loading frame 5, and a material transfer mechanism is set on the receiving frame 8. When the receiving frame 8 is moved directly below the loading frame 5 by the control of the rodless cylinders 7, the material transfer mechanism transfers the material, and the upper lens 6 automatically falls onto the blocking mechanism to receive the material. Then, the receiving frame 8 is moved to the left directly above the placement tray 2 by the control of the rodless cylinders 7. After the blocking mechanism releases the upper lens 6, the upper lens 6 will automatically fall onto the lower lens 4 for bonding.

[0031] like Figure 1 As shown, the material transfer mechanism includes a conveying component 9. The symmetrically arranged conveying components 9 are installed on the loading rack 5. The conveyor belt on the conveying component 9 is fixedly connected with equal-spaced first rubber blocks 10. The left and right symmetrical first rubber blocks 10 are used to support the upper lens 6, so that the upper lens 6 is kept in a stacked distribution. The conveying component 9 is controlled by a power source. When feeding, the power source can control the conveying component 9 to rotate, so that the upper lens 6 falls to the upper part of the receiving rack 8.

[0032] like Figure 2 and Figure 3As shown, the blocking mechanism includes a movable block 11, which is symmetrically and slidably connected to the receiving rack 8. A second rubber block 12 is fixedly connected to the movable block 11 on the side closer to each other. The second rubber block 12 is used to support the upper lens 6. A first spring 13 is connected between the movable block 11 on the side farther from each other and the receiving rack 8. After the upper lens 6 moves above the lower lens 4, the movable block 11 can be pulled outward, the first spring 13 is compressed, and the movable block 11 pulls out, causing the second rubber block 12 to move away and release the upper lens 6. The upper lens 6 will then automatically fall down for bonding. After the movable block 11 is released, the first spring 13 will drive the movable block 11 and the second rubber block 12 to move and reset.

[0033] As mentioned above, after clamping the lower lens 4, it is necessary to manually drip glue onto the lower lens 4, which is quite troublesome. Therefore, this embodiment proposes the following solution:

[0034] like Figure 4 and Figure 5 As shown, a sliding block 14 is slidably connected between the rodless cylinders 7. The sliding block 14 is fixedly connected to the receiving rack 8. A glue storage cylinder 15 for storing glue is provided in the middle of the sliding block 14. A glue outlet 16 is connected to the bottom of the glue storage cylinder 15. A conical block 17 is slidably connected inside the glue outlet 16. A second spring 18 is connected between the upper part of the conical block 17 and the glue outlet 16.

[0035] When the receiving rack 8 moves to the right, the receiving rack 8 drives the sliding block 14 to move to the right, the sliding block 14 drives the glue storage cylinder 15 to move to the right, and the glue storage cylinder 15 drives the glue dispensing head 16 to move directly above the lower lens 4. At this time, the receiving rack 8 moves directly below the loading rack 5. At this time, a power source can squeeze the cone block 17, causing the cone block 17 to move upward and open the glue dispensing head 16. The second spring 18 is compressed, so the glue will automatically drip onto the lower lens 4.

[0036] To achieve automated glue dispensing without manual intervention, a push-pull rod 19 is fixedly connected to the bottom of the cone block 17. Symmetrically arranged rotating columns 20 are rotatably connected to the push-pull rod 19. The rotating columns 20 and the placement tray 2 are in a pressing fit. The placement tray 2 can be controlled by a cylinder to rise. When the placement tray 2 contacts the rotating columns 20, it drives the rotating columns 20 to move upwards. The rotating columns 20 then drive the push-pull rod 19 upwards, which in turn drives the cone block 17 upwards, thus dispensing glue. When receiving material... After receiving the material, the receiving frame 8, sliding block 14, and glue storage cylinder 15 are controlled to move to the left by rodless cylinder 7. At this time, the push-pull rod 19 is pushed upward, and the second spring 18 is compressed. When the push-pull rod 19 moves to the left, the rotating column 20 rotates along the top of the storage tray 2. This can avoid wear between the push-pull rod 19 and the storage tray 2. When the rotating column 20 and the top of the storage tray 2 separate, the second spring 18 drives the cone block 17, push-pull rod 19 and rotating column 20 to descend, blocking the glue outlet 16 again.

[0037] As mentioned above, the transmission component 9 needs to be driven by a power source to operate. In order to improve the automation of the entire device, therefore, as follows: Figure 1 As shown, a rack frame 21 is slidably connected to the side of the workbench 1 near the loading rack 5. The bottom of the rack frame 21 and the bottom of the tray 2 are powered by the same cylinder. A symmetrically arranged one-way gear 22 is fixedly connected to the side of the conveying component 9 away from the tray 2. The one-way gear 22 meshes with the rack frame 21. When the cylinder controls the tray 2 to rise, it will simultaneously drive the rack frame 21 to move upward. The upward movement of the rack frame 21 will drive the one-way gear 22 to rotate. The one-way gear 22 will drive the conveying component 9 to rotate, thereby causing the upper lens 6 to be conveyed downward. After the gluing is completed, the tray 2 is controlled to descend by the cylinder, which will simultaneously drive the rack frame 21 to descend. At this time, the one-way gear 22 will idle, and the conveying component 9 will not rotate.

[0038] It should be noted that a limiting mechanism is provided on the conveying component 9. The limiting mechanism consists of an elastic protrusion and a groove. When the conveying component 9 rotates, the elastic protrusion and the groove cooperate to limit the movement of the conveying component 9. The limiting mechanism is a common existing mechanism, and will not be elaborated on in this embodiment.

[0039] After the upper lens 6 and lower lens 4 are firmly attached, people usually use a rubber pen to press and shake the top of the upper lens 6 to remove air bubbles in the adhesive layer, distribute the adhesive layer evenly, and enhance the lens fit. However, manually shaking is cumbersome, so the following solution is provided:

[0040] like Figure 2As shown, the device includes a support frame 23, which is positioned between the top of the rodless cylinder 7. An electric push rod 24 is fixedly connected to the middle of the support frame 23. A lifting frame 25 is fixedly connected to the bottom of the telescopic rod of the electric push rod 24. The lifting frame 25 and the support frame 23 are slidably connected. A servo motor 26 is positioned in the middle of the lifting frame 25. The output shaft of the servo motor 26 is fixedly connected to a bend rod 271. A swing ball 27 is positioned at the bottom of the bend rod 271. The swing ball 27 is rotatably connected to the lower part of the lifting frame 25. A swing disk 28 is fixedly connected to the swing ball 27. A rubber column 29 is slidably connected to the lower part of the lifting frame 25 along the circumferential direction. The top of the rubber column 29 and the swing disk 28 are press-fitted together. A third spring 30 is connected between the rubber column 29 and the lifting frame 25.

[0041] When the upper lens 6 falls onto the lower lens 4, the electric push rod 24 drives the lifting frame 25 to descend. The lifting frame 25 drives the rubber column 29 to descend. After the bottom of the rubber column 29 and the top circumference of the upper lens 6 are in contact, the servo motor 26 is turned on. The servo motor 26 drives the bent rod 271 and the swing ball 27 to rotate, causing the swing disk 28 to swing in the circumferential direction. The swing disk 28 continuously squeezes the rubber column 29, causing the rubber column 29 to descend and press the upper lens 6. After the swing disk 28 and the rubber column 29 separate, the third spring 30 drives the rubber column 29 to rise and reset. The rubber column 29 presses the upper lens 6 in sequence, thus simulating the effect of manually pressing and shaking the upper lens 6. After the shaking is completed, the servo motor 26 is turned off, and the electric push rod 24 is controlled to retract and reset, driving the lifting frame 25, the swing disk 28 and the rubber column 29 to rise and reset.

[0042] When the rubber pillars 29 press down on the upper lens 6 in sequence, the upper lens 6 may shift. To address this, a rubber abutment 31 is fixedly connected to the bottom center of the lifting frame 25. The bottom of the rubber abutment 31 is used to abut against the middle position of the optical lens. When the lifting frame 25 descends, the rubber abutment 31 will also descend and abut against the top position of the upper lens 6. In this way, the rubber abutment 31 can press down on the upper lens 6 and prevent the upper lens 6 from shifting from the side.

[0043] As mentioned earlier, the second rubber block 12 needs to be manually moved away, which is very inconvenient. Therefore, wedge blocks 32 are fixedly connected to both the front and rear sides of the lifting frame 25, and columns 33 are set on both sides of the moving block 11. The columns 33 and the wedge blocks 32 are pressed together.

[0044] When the lifting frame 25 descends, it drives the wedge block 32 to descend. Before the rubber column 29 contacts the upper lens 6, the bottom of the wedge block 32 will first contact the column 33 and push the column 33 to move away from each other, thereby causing the second rubber block 12 to move outward and release the upper lens 6. This can achieve the effect of automatic material release. When the lifting frame 25 rises, it drives the wedge block 32 to rise and separate from the column 33. The first spring 13 drives the moving block 11 and the second rubber block 12 to move and reset.

Contents not described in detail in this invention are existing technologies known to those skilled in the art.
