Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, and in particular to a lens dispensing and curing device. Background Technology

[0002] Lens dispensing and curing equipment is a specialized device for lens dispensing and curing processes. It features high processing precision and a high degree of automation, enabling precise control of dispensing position, dispensing amount, and curing time, thereby improving production efficiency and product quality.

[0003] In actual production, existing lens dispensing and curing devices often experience glue residue adhering to the outer wall of the dispensing needle as the number of dispensing cycles increases. In some cases, the glue may even solidify on the outer wall of the dispensing needle. This not only affects the accuracy of the dispensing position but also makes cleaning difficult and may even require machine shutdown for cleaning, thus impacting production efficiency.

[0004] In existing technologies, the adhesive removal structure is often set on the dispensing assembly, and the adhesive on the dispensing needle is blown away by airflow. This method not only has low cleaning efficiency and is not easy to remove completely, but also requires additional auxiliary equipment such as airflow pipelines and air sources, which increases the structural complexity of the lens dispensing and curing device.

[0029] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. Directional terms used in this application, such as X-axis, Y-axis, and Z-axis, are all indicated by the appendix. Figure 1 The coordinates in the figure are used as a reference. Meanwhile, each pre-cured surface light source assembly 5 in this application is provided with a cover 500, attached with... Figure 1 Only one cover 500 is shown in the image. The covers 500 corresponding to the other pre-cured surface light source components 5 are hidden so that the curing head can be seen directly.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] To address the low production efficiency of existing lens dispensing and curing devices, this embodiment proposes a lens dispensing and curing device, as shown in the attached figure. Figure 1-7As shown, the lens dispensing and curing device includes at least three sets of dispensing pre-curing devices and at least two sets of aging Y-axis assemblies 6 arranged sequentially along the X-axis. The dispensing pre-curing device includes a dispensing Y-axis assembly 3, a dispensing assembly 4, and a pre-curing surface light source assembly 5. The dispensing assembly 4 is located at one end of the dispensing Y-axis assembly 3 and can dispense adhesive onto the lens 10 carried on the dispensing Y-axis assembly 3. The pre-curing surface light source assembly 5 is located at the other end of the dispensing Y-axis assembly 3 and can perform pressure pre-curing under pressure on the lens 10. The lens dispensing and curing device cures the lens 10 through the pre-curing surface light source assembly 5 or the aging Y-axis assembly 6, or cures the lens 10 sequentially through the pre-curing surface light source assembly 5 and the aging Y-axis assembly 6.

[0034] That is, this application can complete the curing of the lens 10 by only using the pre-cured surface light source assembly 5 in the form of pressure pre-curing, or it can complete the curing of the lens 10 by only using the aging process, or it can complete the curing of the lens 10 by sequentially performing pressure pre-curing and aging.

[0035] Therefore, by setting up at least three sets of dispensing pre-curing devices and at least two sets of aging Y-axis assemblies 6, this application can effectively accelerate the curing cycle of the lens 10, thereby solving the problem of the slow working rhythm of the curing station in existing lens dispensing curing devices and effectively improving the production efficiency of the lens dispensing curing device. Simultaneously, the curing process of the lens 10 can be completed through at least three curing methods. On the one hand, it can be flexibly adjusted according to the actual operating rhythm of different lens production lines, ensuring that the production line operates at a high production efficiency while meeting actual production requirements, thus improving the applicability of the lens dispensing curing device to different lens production lines. On the other hand, since the lens dispensing curing device can provide multiple forms of curing operations, it can effectively meet the actual curing requirements of different lenses.

[0036] The lens dispensing and curing device includes an X-axis track 2. The dispensing pre-curing device and the aging Y-axis assembly 6 are both located below the X-axis track 2. A dispensing loading robot 201 and a unloading Z-axis assembly 203 are respectively mounted on the X-axis track 2. The dispensing loading robot 201 can move along the X-axis track 2 to transfer the lens 10 to the dispensing Y-axis assembly 3. The unloading Z-axis assembly 203 can move along the X-axis track 2 to transfer the pressure-pre-cured lens 10 to the aging Y-axis assembly 6, the cutting assembly 801, or the NG receiving tray 802, or to the aging lens 10 to the cutting assembly 801 or the NG receiving tray 802. Specifically, for the pressure-pre-cured lens 10, if further aging is required, it is transferred to the aging Y-axis assembly 6; otherwise, it can be transferred to the cutting assembly 801 or the NG receiving tray 802. The cutting assembly 801 is a conventional device for transferring lenses 10 that have passed the adhesive dispensing and curing process to subsequent processes. The NG receiving tray 802 is a device for collecting lenses 10 that have failed the adhesive dispensing and curing process. Since both are conventional devices in the field and are not the main technical content of this application, they will not be described in detail.

[0037] As attached Figure 7 As shown, in this application, the structures of the dispensing and loading robot 201 and the unloading Z-axis assembly 203 can be identical. Taking the dispensing and loading robot 201 as an example, it includes a material Z-axis track 901. Connecting plates 902 are respectively provided on both wings of the material Z-axis track 901. The connecting plates 902 can move along the material Z-axis track 901. A gripper assembly 903 is provided at the lower end of each connecting plate 902 for gripping the lens 10. In this application, for the same dispensing and loading robot 201, the connecting plates 902 on both wings can move independently, synchronously, or asynchronously. The description of the unloading Z-axis assembly 203 is consistent with the above and will not be repeated.

[0038] A dispensing camera 202 and a detection camera 204 are respectively installed on the X-axis track 2. The dispensing camera 202 can move along the X-axis track 2 to acquire images of the lenses 10 to be dispensed on each dispensing Y-axis assembly 3. Specifically, it acquires the position of the lens 10 in the dispensing groove before dispensing, so as to adjust the lens 10 to the preset dispensing starting position, and then perform dispensing through the dispensing assembly 4. This ensures that each lens 10 is in the preset dispensing starting position before dispensing, which can effectively improve the final yield rate. The detection camera 204... It can move along the X-axis track 2 to acquire images of each lens 10 after curing, so as to facilitate the quality inspection of dispensing curing. Specifically, it can be determined by manual inspection or existing image comparison technology or AI image recognition technology to determine whether the lens 10 has defects such as dispensing breaks or blistering. If so, the unqualified lens 10 is transferred to the NG receiving tray 802 in a timely manner through the unloading Z-axis assembly 203. This can effectively detect and remove unqualified lenses 10, which helps to ensure the quality of the final product and effectively improve production efficiency.

[0039] The aging Y-axis assembly 6 includes a curing tray 601, an aging Y-axis track 602, and an aging light source box 7. One end of the aging Y-axis track 602 is connected to the aging light source box 7. The curing tray 601 is used to hold lenses 10 that need to be aged, and can hold multiple lenses 10. The curing tray 601 can move along the aging Y-axis track 602, so that after a certain number of lenses 10 are placed on the curing tray 601, it can move along the aging Y-axis track 602 to the aging light source box 7 for batch aging, thereby improving the curing efficiency of the lenses 10. Furthermore, this application provides at least two sets of aging Y-axis assemblies 6, so that while one set of aging Y-axis assemblies 6 is undergoing aging, the other set is loading lenses, ensuring continuous operation of the production line and improving production efficiency.

[0040] The lens dispensing and curing device includes a base plate 1. The X-axis track 2 has supporting feet and is connected to the base plate 1 through the supporting feet. The dispensing Y-axis assembly 3, dispensing assembly 4, pre-cured surface light source assembly 5, aging Y-axis track 602, aging light source box 7, cutting assembly 801, NG receiving tray 802 and other components are all connected to the base plate 1, so that the lens dispensing and curing device can operate on a stable platform.

[0041] For the dispensing Y-axis assembly 3, dispensing assembly 4, and pre-cured surface light source assembly 5, the content described in this embodiment is the same as that in embodiment 2. Please refer to embodiment 2 for details.

[0042] Example 2

[0043] This embodiment, based on embodiment 1, introduces the dispensing Y-axis assembly 3, dispensing assembly 4, pre-cured surface light source assembly 5, and corresponding structural improvements.

[0044] The dispensing assembly 4 includes a servo motor 402, a dispensing Z-axis assembly, and a glue cartridge 403. The glue cartridge 403 is engaged with the dispensing Z-axis assembly, which can drive the glue cartridge 403 to move along the Z-axis (i.e., the vertical direction). The servo motor 402 is connected to the dispensing Z-axis assembly and can drive the dispensing Z-axis assembly and the glue cartridge 403 to swing in the vertical plane, thereby adjusting the dispensing angle of the dispensing needle 404 of the glue cartridge 403 to achieve tilted dispensing at a specific angle.

[0045] The dispensing Z-axis assembly includes a second motor 406, a dispensing Z-axis track 407, and a connecting assembly 408. The servo motor 402 is connected to the dispensing Z-axis track 407, and the second motor 406 is fixedly connected to the dispensing Z-axis track 407. The output end of the second motor 406 is connected to the connecting assembly 408 via a conventional transmission component, and can drive the connecting assembly 408 to move along the dispensing Z-axis track 407. The connecting assembly 408 engages with the glue cartridge 403. This allows the servo motor 402 to drive the dispensing Z-axis assembly and the glue cartridge 403 to swing in a vertical plane, while the dispensing Z-axis assembly can drive the glue cartridge 403 to move along the Z-axis.

[0046] For the engagement between the connecting component 408 and the glue tube 403, the connecting component 408 is provided with a support arm 409 and a limiting arm 410 on the side facing the glue tube 403. The limiting arm 410 is located below the support arm 409. The support arm 409 sleeves the outer wall of the glue tube 403 to achieve the engagement of the glue tube 403 in the horizontal direction. The limiting arm 410 supports and limits the outer wall of the lower end of the glue tube 403. Specifically, the limiting hole of the limiting arm 410 is larger than the minimum diameter of the glue tube 403 at the end of the dispensing needle 404, but smaller than the maximum diameter of the glue tube 403. Thus, after the lower part of the glue tube 403 passes through the limiting hole of the limiting arm 410, the limiting arm 410 can effectively limit the glue tube 403 and prevent the glue tube 403 from moving further downward. Thus, through the combined action of the support arm 409 and the limiting arm 410, the rubber sleeve 403 can be assembled with the connecting component 408 relatively stably.

[0047] The glue cartridge 403 is a conventional structure in the art, with a dispensing needle 404 at the lower end and a glue injection tube 405 at the upper end, which can replenish glue into the glue cartridge 403. In addition, the dispensing assembly 4 includes a support 401, with a servo motor 402 at the upper end and connected to the base plate 1 at the lower end.

[0048] In actual production, existing lens dispensing and curing devices often experience glue residue adhering to the outer wall of the dispensing needle as the number of dispensing cycles increases. In some cases, the glue may even solidify on the outer wall of the dispensing needle. This not only affects the accuracy of the dispensing position but also makes cleaning difficult and may even require machine shutdown for cleaning, thus impacting production efficiency.

[0049] Therefore, this embodiment improves the dispensing Y-axis assembly 3. The dispensing Y-axis assembly 3 includes a dispensing Y-axis track 301 and a base 307. The base 307 can move along the dispensing Y-axis track 301. A four-jaw cylinder 302 and a glue-cleaning mechanism 303 are provided on the base 307. The four-jaw cylinder 302 can clamp the lens 10 and drive the lens 10 to rotate. The glue-cleaning mechanism 303 can clamp and wipe the dispensing needle 404 of the dispensing assembly 4. Therefore, after each dispensing operation or after a certain number of dispensing cycles, there is no need to stop the machine. The glue adhering to the dispensing needle 404 can be removed simply by wiping it with the glue-cleaning mechanism 303 on the Y-axis dispensing assembly 3. Compared with existing glue-cleaning structures, this method not only has higher glue removal efficiency on the dispensing needle 404, ensuring its cleanliness and normal operation, but also guarantees the continuous and normal operation of the lens dispensing and curing device. Simultaneously, it effectively reduces the structural complexity of the dispensing assembly 4 and the lens dispensing and curing device.

[0050] The adhesive removal mechanism 303 includes at least two adhesive removal claws 304. Any two adhesive removal claws 304 can move closer or further apart to clamp and wipe the dispensing needle 404 of the dispensing assembly 4. When it is necessary to wipe the dispensing needle 404, the adhesive removal claws 304 move to the dispensing needle 404, retract, and clamp the dispensing needle 404. Then, the glue cylinder 403 moves upward under the drive of the second motor 406, causing the dispensing needle 404 to be pulled out from the adhesive removal claws 304, thus achieving the wiping of the dispensing needle 404. Preferably, the adhesive removal claws 304 are equipped with sponges or lint-free cloths to ensure good cleaning ability and avoid rigid collisions or scraping of the dispensing needle 404 during wiping.

[0051] For the rotation of the four-jaw cylinder 302, a first motor 305 is installed on the base 307. The first motor 305 is connected to the four-jaw cylinder 302 through a conventional transmission component and can drive the four-jaw cylinder 302 to rotate. In addition, a photoelectric switch 306 can also be installed on the dispensing Y-axis track 301 to detect whether the lens 10 is clamped on the four-jaw cylinder 302 before dispensing, so as to ensure the normal operation of the relevant equipment and to detect malfunctions in a timely manner.

[0052] Since adhesives often contain a certain amount of volatile components, these volatile components tend to evaporate from the adhesive and adhere to the lens surface during the curing process after application, thus contaminating the lens and affecting the quality of the final lens product.

[0053] Therefore, this embodiment improves the pre-cured surface light source assembly 5. The pre-cured surface light source assembly 5 includes a Z-axis motion mechanism and a curing pressure rod 505. One end of the curing pressure rod 505 is connected to the Z-axis motion mechanism and can move along the Z-axis under the drive of the Z-axis motion mechanism. The other end of the curing pressure rod 505 is provided with a pressure head 506. The pressure head 506 can apply pressure to the lens of the lens 10. The outer wall of the pressure head 506 is provided with an air blowing port 507, which can blow air onto the lens during the pre-curing process. As the airflow flows, it can carry away the volatile components in the adhesive and prevent them from adhering to the lens surface. At the same time, it can also realize the pressure of the pre-cured surface light source assembly 5 on the lens.

[0054] The curing rod 505 is equipped with an air blowing pipe inside. One end of the air blowing pipe is connected to an air source, and the other end is connected to an air blowing port 507. Thus, this application can make the curing rod 505 into a hollow rod, which not only has a simple structure, but also ensures the normal operation of actions such as applying pressure to the lens and blowing air.

[0055] The pre-cured surface light source assembly 5 also includes a cover 500 and a pre-cured surface light source (not shown). The cover 500 is connected to a curing pressure rod 505 and / or a Z-axis motion mechanism. The pressure head 506 is located inside the cover 500. The pre-cured surface light source can project UV light into the cover 500, specifically towards the dispensing position of the lens 10. Thus, when the lens 10 moves below the pre-cured surface light source assembly 5 along with the dispensing Y-axis assembly 3, the cover 500 and the curing pressure rod 505 descend together, the pressure head 506 applies pressure to the lens of the lens 10, and the pre-cured surface light source projects UV light towards the dispensing position of the lens 10, realizing the pressure pre-curing of the lens by the pre-cured surface light source assembly 5. The lower part of the cover 500 has an opening corresponding to the lens 10, so that the lens 10 and related components can enter the cover 500, preventing UV light from escaping.

[0056] The Z-axis motion mechanism includes a first cylinder 502, a connecting block 503, and a second cylinder 504. The connecting block 503 is fixedly connected to the curing rod 505. The second cylinder 504 is connected to the connecting block 503 via a conventional transmission component (such as a slider) and is used to drive the connecting block 503 and the curing rod 505 to move along the Z-axis. The first cylinder 502 is connected to the second cylinder 504 via a conventional transmission component and is used to drive the second cylinder 504, the connecting block 503, and the curing rod 505 to move along the Z-axis. The downward pressure provided by the first cylinder 502 is greater than the downward pressure provided by the second cylinder 504.

[0057] Therefore, during the pressure pre-curing process for different lenses, the first cylinder 502 can provide greater pressure, while the second cylinder 504 can provide less pressure, depending on the different force requirements of the lens, to meet the pressure pre-curing requirements and pressure accuracy requirements of different lenses. Simultaneously, since the first cylinder 502 can drive the second cylinder 504 to move, the two can combine to form two strokes. When the first cylinder 502 has a larger stroke, the stroke capacity of the second cylinder 504 can be reduced. When pressure is required from the second cylinder 504, the first cylinder 502 first moves the second cylinder 504, connecting block 503, and curing rod 505 to the target position, and then the second cylinder 504 applies downward pressure to the connecting block 503 and curing rod 505.

[0058] In addition, the pre-cured surface light source assembly 5 includes a base 501, the upper part of which is connected to the Z-axis motion mechanism, and the lower end of which is connected to the base plate 1.

[0059] To facilitate understanding of the relevant operational process, this application uses the sequential processes of dispensing, pressure pre-curing, and aging as an example to describe the related actions. The main function of the lens dispensing and curing device is to dispense and fix the lens assembled by the assembly machine in the upstream process. The dispensing position is generally at the dispensing groove reserved on the side wall of the lens barrel. First, the dispensing and feeding robot 201 picks up the lens 10 from the cutting assembly of the assembly machine and moves the lens 10 onto the four-jaw cylinder 302 of the dispensing Y-axis assembly 3. The dispensing Y-axis assembly 3 moves the lens 10 to below the dispensing camera 202. The dispensing camera 202 records the position of the dispensing groove corresponding to the lens 10. Based on this, the four-jaw cylinder 302... The claw cylinder 302 rotates the lens 10 to the preset dispensing starting position. The dispensing Y-axis assembly 3 then moves the lens 10 below the dispensing assembly 4, where the dispensing assembly 4 performs the dispensing. During the dispensing process, the first motor 305 drives the four-jaw cylinder 302 to rotate the lens, thus dispensing the glue into the dispensing groove. After dispensing, the dispensing Y-axis assembly 3 moves the lens 10 below the pre-curing surface light source assembly 5. The pre-curing surface light source descends and applies pressure to the lens 10 for pre-curing via the curing pressure rod 505. The pre-cured lens is then transferred to the curing tray 601 by the unloading Z-axis assembly 203. The curing tray 601 then moves to the aging light source box 7 for aging. After aging, the lens 10 moves to the underside of the inspection camera 204 along with the curing tray 601. The inspection camera 204 captures an image of the corresponding lens 10 to perform dispensing quality inspection and determine whether there are defects such as broken dispensing or bulging. After the inspection is completed, the lens 10 is picked up by the unloading Z-axis assembly 203 and transferred from the unloading Z-axis assembly 203 to the cutting assembly 801 or the NG receiving tray 802, depending on whether the dispensing curing is qualified. The cutting assembly 801 will transfer qualified lenses to subsequent processes.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
