Description

Technical Field

[0001] This invention relates to the technical field of lens processing, and more specifically to a device for applying and curing adhesive to lens retaining rings. Background Technology

[0002] During lens assembly, a retaining ring is installed at the end of the lens to fix the lens element inside. Adhesive needs to be applied at the connection between the retaining ring and the lens. After the adhesive is applied, the adhesive needs to be cured to completely fix the retaining ring to the lens and prevent the retaining ring from loosening.

[0003] Chinese invention patent CN120696036B discloses a lens pressing ring dispensing device. This device uses a structure that cures lenses one by one. For lenses that require a long curing time, this curing structure will slow down the production efficiency of the entire device. Moreover, this device is used as a single unit and cannot be used in a production line with the preceding lens assembly equipment. Therefore, a new device solution for lens pressing ring dispensing and curing is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a device for dispensing and curing lens retainers, aiming to overcome the shortcomings of existing technologies. This device includes an X-axis handling robot for transporting lenses. Along the transport trajectory of the X-axis handling robot are sequentially arranged a lens dispensing assembly, a lens curing assembly, an adhesive quality inspection assembly, an NG (not good) receiving assembly, and an OK (good) product cutting assembly. The lens curing assembly further includes two strip-shaped UV irradiators positioned opposite each other and spaced apart along the X-axis, extending along the Y-axis. A curing Y-axis linear module is disposed between the two strip-shaped UV irradiators. Multiple support seats are arranged along the Y-axis on the drive plate of the curing Y-axis linear module, and a drive component capable of driving the multiple support seats to rotate synchronously is provided on the drive plate of the curing Y-axis linear module.

[0005] In one specific embodiment, the rotation directions of two adjacent bearing seats are opposite, or the rotation directions of the multiple bearing seats are all the same.

[0006] In one specific embodiment, a curing carrier is provided on the drive plate of the curing Y-axis linear module, and a plurality of the bearing seats are rotatably mounted on the curing carrier; the bearing seat is provided with an air channel coaxial with its rotation axis, and a limiting groove coaxial with and connected to the air channel is provided on the top of the bearing seat; the bottom of the air channel is connected to a vacuum generator through an air pipe to fix the lens in the limiting groove.

[0007] In one specific embodiment, the driving component includes a synchronous belt and a drive motor, a synchronous pulley is provided at the bottom of the support base, the output end of the drive motor is drivenly connected to the synchronous belt, and the synchronous belt is drivenly connected to the synchronous pulley.

[0008] In one specific embodiment, a protective cover is provided at the bottom of the curing carrier, and the timing belt and the timing pulley are located inside the protective cover.

[0009] In one specific embodiment, a light-shielding plate is also provided between the lens dispensing assembly and the lens curing assembly.

[0010] In one specific embodiment, the X-axis handling robot is a dual-moving robot. The first moving part is used to pick up the assembled lens with the pressure ring from the previous process equipment, and first transfer it to the lens dispensing assembly to apply glue to the connection between the pressure ring and the lens, and then transfer it to the carrier of the lens curing assembly to cure the glue. The second moving part is used to pick up the cured lens from the carrier, and first transfer it to the glue quality inspection assembly for inspection, and then transfer the lens to the NG receiving assembly or OK product cutting assembly according to the inspection result.

[0011] In one specific embodiment, the lens dispensing assembly includes a Y-axis linear dispensing module, a dispensing positioning camera, a Z-axis linear dispensing module, and a dispensing needle. The dispensing needle is disposed on the drive plate of the Z-axis linear dispensing module. The dispensing positioning camera and the dispensing needle are located above the movement trajectory of the drive plate of the Y-axis linear dispensing module. The drive plate of the Y-axis linear dispensing module is provided with a dispensing fixture and a dispensing rotary motor for driving the dispensing fixture to rotate. A first actuator transfers the lens onto the dispensing fixture, and dispensing is completed under the coordinated cooperation of the Y-axis linear dispensing module, the dispensing positioning camera, the Z-axis linear dispensing module, the dispensing needle, and the dispensing rotary motor.

[0012] In one specific embodiment, a connecting plate is also suspended on the drive plate of the dispensing Y-axis linear module. The connecting plate is provided with a receiving through hole, in which a glue receiving box is placed. Furthermore, a pair of clearance notches are provided on the receiving through hole to facilitate the replacement of the glue receiving box.

[0013] In one specific embodiment, a transition carrier is also included. A flipping component is provided on one side of the transition carrier. The pressure ring is an outer pressure ring. The X-axis transport robot picks up the lens with the outer pressure ring assembled from the previous process equipment, first transfers it to the transition carrier, and then flips it using the flipping component so that the glue dispensing position at the connection between the outer pressure ring and the lens faces upward. Then, it is transferred to the lens glue dispensing component for glue dispensing.

[0014] The present invention has at least the following beneficial effects: The curing component of the equipment adopts a design of dual-strip UV irradiators and multiple carriers rotating synchronously, which can achieve 360° curing of multiple lenses simultaneously without dead angles. This not only improves the curing efficiency of the adhesive but also ensures uniform curing and prevents local overheating that could lead to thermal damage to the adhesive layer. The equipment uses an X-axis handling robot to directly pick up lenses with assembled outer pressure rings from the previous process equipment and uses an OK part cutting component to cut out qualified lenses to the next process equipment, enabling assembly line use.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] Please see Figures 1-2 The present invention provides a lens pressing ring dispensing and curing device, including a device working platform 100, an X-axis transport robot 1 for transporting lenses is provided on the device working platform 100, and a lens dispensing component 2, a lens curing component 3, an adhesive quality detection component 4, an NG receiving component 5 and an OK product cutting component 6 are arranged sequentially on the transport trajectory of the X-axis transport robot 1.

[0026] Please see Figure 3 The X-axis handling robot 1 is a dual-moving robot. The first moving part 11 picks up the assembled lens with the pressure ring from the previous process equipment and transfers it to the lens dispensing assembly 2 to apply adhesive to the connection between the pressure ring and the lens. Then, it transfers the lens to the carrier 33 of the lens curing assembly 3 for adhesive curing. The second moving part 12 picks up the cured lens from the carrier 33 and transfers it to the adhesive quality inspection assembly 4 for inspection. Based on the inspection results, the lens is then transferred to the NG receiving assembly 5 or the OK product cutting assembly 6. The adhesive quality inspection assembly 4, the NG receiving assembly 5, and the OK product cutting assembly 6 are all implemented using existing technology, and their specific structures will not be described in detail in this embodiment.

[0027] Please see Figure 4 The lens dispensing assembly 2 includes a dispensing Y-axis linear module 21, a dispensing positioning camera 22, a dispensing Z-axis linear module 23, and a dispensing needle 24. The dispensing needle 24 is mounted on the drive plate of the dispensing Z-axis linear module 23. The dispensing positioning camera 22 and the dispensing needle 24 are located above the motion trajectory of the drive plate of the dispensing Y-axis linear module 21. The drive plate of the dispensing Y-axis linear module 21 is equipped with a dispensing fixture 25 and a dispensing rotary motor 26 that drives the dispensing fixture 25 to rotate. After the first actuator 11 transfers the lens to the dispensing fixture 25, the dispensing Y-axis linear module 21 first drives the dispensing fixture 25 carrying the lens to move below the dispensing positioning camera 22. The dispensing positioning camera 22 obtains the precise dispensing position on the lens. The dispensing Y-axis linear module 21 first drives the dispensing fixture 25 carrying the lens to move below the dispensing needle 24, and then drives the dispensing needle 24 to descend to the dispensing starting position of the lens. The dispensing rotary motor 26 then drives the dispensing fixture 25 to rotate, thereby driving the lens to rotate, realizing full-circle dispensing or multi-segment dispensing at the connection between the lens and the pressure ring.

[0028] Please see Figure 5 The drive plate of the Y-axis linear dispensing module 21 is also equipped with a glue-wiping cylinder gripper 27. After the dispensing needle 24 completes the dispensing on the lens on the dispensing fixture 25, the Y-axis linear dispensing module 21 drives the lens to move back below the dispensing positioning camera 22. At the same time, the glue-wiping cylinder gripper 27 moves to below the dispensing needle 24. The dispensing positioning camera 22 also detects whether there are defects such as glue leakage, glue breakage, or insufficient glue at the dispensing position. The glue-wiping cylinder gripper 27 clamps the dispensing needle 24, and the wiping cloth on the inner side of the glue-wiping cylinder gripper 27 contacts the dispensing needle 24. Under the drive of the Z-axis linear dispensing module 23, the dispensing needle 24 is pulled away from the glue-wiping cylinder gripper 27, thus wiping the dispensing needle 24 to prevent glue residue from affecting the subsequent dispensing quality.

[0029] For further details, please refer to Figure 5 A connecting plate 211 is suspended on the drive plate of the dispensing Y-axis linear module 21. The connecting plate 211 has a receiving through-hole, within which a glue receiving box 28 is placed. When the dispensing Y-axis linear module 21 drives the lens back to the position where it aligns with the second mover 12, the glue receiving box 28 is positioned directly below the dispensing needle 24 to catch any glue that may overflow from the dispensing needle 24, preventing glue from flowing onto the dispensing Y-axis linear module 21. The glue receiving box 28's placement within the receiving through-hole allows for periodic replacement. Furthermore, a pair of clearance notches 2111 are provided on the sides of the receiving through-hole, making the replacement of the glue receiving box 28 very convenient.

[0030] Please see Figure 4 An electronic magnifying glass 29 is also provided on one side of the dispensing Y-axis linear module 21 to collect dispensing video and connect to the display screen of the equipment system, so that the dispensing details can be viewed in real time through the display screen, making it convenient for operators to understand the dispensing status.

[0031] Please see Figures 6-8 The lens curing assembly 3 further includes two strip-shaped UV irradiators 31 that are positioned opposite each other and spaced apart in the X-axis direction, and the two strip-shaped UV irradiators 31 extend along the Y-axis direction. A curing Y-axis linear module 32 is disposed between the two strip-shaped UV irradiators 31. Multiple support seats 33 are arranged along the Y-axis direction on the drive plate of the curing Y-axis linear module 32, and a drive component 34 capable of driving the multiple support seats 33 to rotate synchronously is disposed on the drive plate of the curing Y-axis linear module 32.

[0032] Because the dispensing trajectory of some lenses is not a perfect circle, such as in multi-segment dispensing, if all lenses rotate in the same direction, the initial phase may be the same, leading to an accumulation of curing phase deviation. Reversing the rotation of adjacent lenses can disrupt the phase correlation, allowing different lenses to receive the main light intensity at different angles, thus averaging out minor process deviations. Most importantly, since lens rotation generates weak airflow, rotating all lenses in the same direction may create localized eddies or heat accumulation. Reversing the rotation of adjacent lenses helps to disrupt the boundary layer and promote uniform heat dissipation. Therefore, in this embodiment, the multiple support seats 33 are designed such that adjacent support seats 33 rotate in opposite directions to meet the needs of lenses with special requirements.

[0033] Of course, in other embodiments of the present invention, for lenses with less stringent curing requirements, the rotation directions of the multiple support seats 33 can also be set to be the same.

[0034] Specifically, in this embodiment, a curing carrier 35 is provided on the drive plate of the curing Y-axis linear module 32, and multiple carrier seats 33 are rotatably mounted on the curing carrier 35. Each carrier seat 33 is provided with an air channel coaxial with its rotation axis, and a limiting groove 331 coaxial with and connected to the air channel is provided on the top of the carrier seat 33. The bottom of the air channel is connected to a vacuum generator through an air pipe. The lens that has been dispensed is placed into the limiting groove 331 under the action of the first mover 11, and the lens is fixed in the limiting groove 331 by the negative pressure generated in the air channel by the vacuum generator.

[0035] Preferably, the driving component 34 includes a synchronous belt 341 and a drive motor 342. A synchronous pulley 332 is provided at the bottom of the support 33. The output end of the drive motor 342 is connected to the synchronous belt 341, and the synchronous belt 341 is connected to the synchronous pulley 332. Using the synchronous belt 341 as the transmission component allows for simultaneous transmission with multiple synchronous pulleys 332, and the multiple synchronous pulleys 332 can be alternately arranged on the inner and outer sides of the synchronous belt 341, resulting in opposite rotation directions for adjacent support 33s. Compared to rack and pinion or gear sets, the synchronous belt 341 transmission method is simpler in structure, lower in cost, and can be flexibly arranged as needed.

[0036] Please see Figures 1-2 In this embodiment, to further improve efficiency, two sets of lens dispensing assemblies 2 are provided, and the two sets of lens dispensing assemblies 2 operate alternately. Since the lens curing assembly 3 adopts a structural design in which multiple carrier seats 33 are arranged between two strip UV irradiators 31, even if two or more sets of lens dispensing assemblies 2 are provided in the preceding stage, the lens curing assembly 3 does not need to be provided with two or more sets accordingly. Instead, the number of carrier seats 33 only needs to be increased accordingly, which greatly simplifies the structural design and reduces the design and manufacturing costs.

[0037] Furthermore, a protective cover 36 is provided at the bottom of the curing carrier 35, and a timing belt 341 and a timing pulley 332 are provided inside the protective cover 36 to prevent debris from entering the transmission components and affecting the stability of the transmission components.

[0038] For further details, please refer to Figure 2 A light shield 7 is also provided between the strip UV irradiator 31 and the dispensing needle 24 to prevent the optical fiber of the strip UV irradiator 31 from irradiating the dispensing needle 24 and curing the glue inside the dispensing needle 24.

[0039] Since the previous process equipment may not have flipped the lens for assembling the outer pressure ring, after the lens for assembling the outer pressure ring is transferred to this equipment, it needs to be flipped so that the connection between the lens and the outer pressure ring faces upwards, facilitating subsequent glue dispensing. Specifically, in this embodiment, please refer to... Figures 1-2 It also includes a transition carrier 8, on one side of which is a flipping component 9. If the lens transferred from the previous process equipment is a lens with an assembled outer pressure ring that has not been flipped, the X-axis handling robot 1 picks up the lens with the assembled outer pressure ring from the previous process equipment, first transfers it to the transition carrier 8, uses the flipping component 9 to flip it, and then transfers it to the dispensing fixture 25. The specific structure of the flipping component 9 can be implemented using existing technology and will not be described in detail here.

[0040] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
