Description

Technical Field

[0001] This invention relates to the field of optical lens assembly technology, and in particular to an optical lens processing clamping device. Background Technology

[0002] In the assembly process of the optical lens module and the connector, UV adhesive is usually used to achieve a fixed connection between the two. Specifically, a ring-shaped adhesive layer is first pre-set on the top wall of the connector, and then the lens module is pressed onto the connector. The adhesive is then spread in the bonding surface between the two and cured under a lamp, thereby achieving a permanent bond between the lens module and the connector.

[0003] Currently, traditional lens module assembly equipment mainly uses a linear pressing method, which involves using a clamping mechanism to press the lens module vertically onto the connector, relying on axial pressure to passively flow and spread the adhesive within the bonding surface. Meanwhile, excess adhesive squeezed out during the pressing process (i.e., overflow adhesive) usually needs to be handled by a separate cleaning process after the pressing step is completed.

[0004] However, linear pressing relies solely on axial pressure to drive the adhesive flow, making it difficult to spread the adhesive evenly on the bonding surface. This can easily lead to problems such as localized insufficient adhesive or excessively thick adhesive layers. Furthermore, tiny air bubbles and gaps in the adhesive are not easily expelled, affecting the bonding strength and consistency. Secondly, excess adhesive squeezed out during the pressing process may contaminate the outer wall of the lens module or surrounding components. A separate post-processing cleaning procedure is not only inefficient but also prone to introducing secondary contamination (such as fiber shedding). Finally, before the adhesive is fully cured, the relative position of the lens module and the connector lacks effective temporary locking. The uncured edge areas of the adhesive may shift due to fluidity, affecting the final assembly accuracy.

[0005] Therefore, in order to improve the spreading and curing effect of adhesive, the present invention provides an optical lens processing clamping device. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing an optical lens processing clamping device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an optical lens processing clamping device, used to clamp and assemble the lens module and the connector during the assembly process, wherein the top wall of the connector is pre-set with an annular adhesive layer, and includes: two symmetrically installed drive arms and clamping components respectively disposed at the ends of the two drive arms.

[0008] The clamping assembly includes a clamping part and a pressing part. The clamping part includes an arc-shaped support plate with an arc-shaped groove and an arc-shaped gripper that slides circumferentially. The arc-shaped gripper is used to clamp the lens module and rotate it circumferentially. The pressing part includes a straight guide groove opened on the outer wall of the arc-shaped support plate and a cover slide that slides vertically. The bottom wall of the cover slide is provided with an arc-shaped pressing strip, which is used to radially squeeze the adhesive layer from the inside to the outside when pressing down.

[0009] The clamping assembly is provided with an auxiliary mechanism, which includes a glue removal section that slides along an arc-shaped slide rail and a rear-mounted illumination section. The glue removal section includes a feeding roller, a receiving roller, and a guide, which are used to drive the glue removal tape to adhere to the overflow glue and roll it up. The illumination section follows the glue removal section and is used to pre-cure the glue removal area at fixed points.

[0010] In the aforementioned optical lens processing clamping device, an arc-shaped support plate is fixedly connected to the end of a drive arm. An arc-shaped groove is provided on the inner ring wall of the arc-shaped support plate. An arc-shaped gripper is slidably engaged on the arc-shaped groove via a connecting slide block. Two arc-shaped grippers are used to slide at a preset angle on the arc-shaped groove to apply a circumferential torsional force to the lens module. The preset angle is 5 to 10 degrees.

[0011] In the aforementioned optical lens processing clamping device, one of the arc-shaped support plates has a snap-fit ​​connector fixedly connected to both ends, and the other arc-shaped support plate has snap-fit ​​grooves adapted to the snap-fit ​​connectors at both ends. The two arc-shaped support plates are joined together to form a ring-shaped stable structure.

[0012] In the aforementioned optical lens processing clamping device, the cover slide includes a semi-circular top plate and a connecting arc plate fixed to the bottom wall of the semi-circular top plate. The connecting arc plate is provided with a guide block that slides in cooperation with the linear guide groove. The two semi-circular top plates are interlocked on their adjacent sides and have mating grooves for interlocking when the two semi-circular top plates are mated.

[0013] In the aforementioned optical lens processing clamping device, the cross-section of the arc-shaped pressing strip is triangular. After two arc-shaped pressing strips are joined together, an annular pressing area is formed. The inner ring protrudes downward and gradually narrows towards the outer ring, so that when the arc-shaped pressing strip moves down, it squeezes the glue from the inner ring to the outer ring.

[0014] In the aforementioned optical lens processing clamping device, an arc-shaped slide rail is provided on the bottom wall of the arc-shaped support plate, and the adhesive removal part also includes a mounting housing that is slidably connected to the arc-shaped slide rail via an electric slider. Each of the two adhesive removal parts is used to slide half a circle to remove the excess adhesive around the joint.

[0015] In the aforementioned optical lens processing clamping device, the feeding roller and the take-up roller are rotatably connected to the mounting housing, and the beginning and end ends of the tape are respectively wound onto the feeding roller and the take-up roller.

[0016] In the aforementioned optical lens processing clamping device, the guide is triangular in shape and mounted on the mounting housing; during the adhesive removal operation, the guide is used to keep the guide adhesive removal tape tangent to the mating point of the lens module and the connector.

[0017] In the aforementioned optical lens processing clamping device, an illumination unit is disposed on a de-adhesive unit, and the illumination unit includes a light shield fixedly connected to a mounting housing and a curing lamp assembled on the mounting housing.

[0018] In the aforementioned optical lens processing clamping device, the drive arm includes a horizontal drive module for driving the clamping components to move closer or further apart from each other, and a vertical drive module for driving the clamping components to rise and fall, and the two drive arms move symmetrically and synchronously.

[0019] Compared with existing technologies, the advantages of this invention are: the uniformity and strength of adhesive bonding are significantly improved by the triple combined motion of axial pressing, circumferential torsion and radial pressing; and the timely cleaning of excess adhesive and position locking are achieved through the coordinated design of adhesive removal and follow-up pre-curing.

[0020] The clamping and pressing parts of the clamping assembly work together. Axial pressing achieves initial positioning and adhesive layer compression between the lens module and the connector. Circumferential torsion effectively removes tiny air bubbles and gaps in the adhesive through shearing action. Radial pressing uses an arc-shaped pressing strip to gradually squeeze the adhesive from the inner to the outer ring. These three actions work together to ensure that the adhesive is evenly spread and densely filled within the bonding surface, effectively solving problems such as localized insufficient adhesive, excessive adhesive layer thickness, or air gaps common in traditional linear pressing methods, significantly improving bonding strength and consistency.

[0021] The adhesive removal section's unwinding and rewinding structure uses two staggered adhesive removal sections that slide symmetrically along an arc-shaped guide rail. This causes the adhesive removal tape to make tangential contact with the outer ring at the joint, continuously adhering to and winding up any excess adhesive onto the take-up roller. This effectively prevents adhesive spillage from contaminating the lens module's outer wall and surrounding components. The illumination section is positioned behind the adhesive removal section's movement trajectory and moves synchronously with it, providing immediate, targeted pre-curing of the areas where adhesive removal has been completed. This collaborative design of "adhesive removal and pre-curing simultaneously" quickly locks the outer edge of the adhesive layer before the adhesive is fully cured, preventing the freshly cleaned edges from overflowing again due to adhesive flow. This lays a stable foundation for subsequent complete curing and significantly reduces the risk of secondary contamination. Attached Figure Description

Detailed Implementation

[0032] 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 are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3 An optical lens processing clamping device is used to clamp and assemble a lens module 100 and a connector 200 during the assembly process, wherein the top wall of the connector 200 is pre-formed with an annular adhesive layer.

[0034] The optical lens processing clamping device of this embodiment includes two symmetrically mounted drive arms 1 and clamping components 2 respectively disposed at the end of each drive arm 1. The two drive arms 1 move symmetrically and synchronously to maintain force balance during clamping, twisting, and adhesive removal. In this embodiment, the drive arm 1 includes a horizontal drive module (not shown in the figure) for driving the clamping components 2 to move closer or further apart, and a vertical drive module (not shown in the figure) for driving the clamping components 2 to rise and fall.

[0035] It should be noted that, in practical implementation, the horizontal and vertical drive modules should employ high-precision servo motors in conjunction with ball screw drives, and the repeatability should be controlled within ±0.01mm to ensure that the clamping assembly 2 does not experience additional positional deviations during closing and lifting. Simultaneously, the horizontal movements of the two drive arms 1 should be synchronously controlled by the same motion controller to avoid jamming or collisions caused by asynchronous left and right movements.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The clamping assembly 2 includes a clamping part 21 and a pressing part 22. The clamping part 21 is responsible for gripping and positioning the lens module 100. Specifically, the clamping part 21 includes an arc-shaped support plate 211 fixedly connected to the end of the drive arm 1. One arc-shaped support plate 211 has a snap-fit ​​connector 213 fixedly connected to its two ends, and the other arc-shaped support plate 211 has snap-fit ​​grooves 214 adapted to the snap-fit ​​connector 213 at its two ends. When the two drive arms 1 approach each other, the two arc-shaped support plates 211 combine through the engagement of the snap-fit ​​connector 213 and the snap-fit ​​groove 214 to form a ring-shaped stable structure, thereby surrounding and positioning the outer periphery of the lens module 100.

[0037] It should be noted that a chamfer is provided at the entrance of the snap-fit ​​groove 214 to guide the two arc-shaped support plates 211 to automatically correct minor misalignments when they are closed.

[0038] Each arc-shaped support plate 211 has an arc-shaped groove on its inner ring wall. An arc-shaped gripper 212 slides along the arc-shaped groove, gripping the outer wall of the lens module 100. In this embodiment, the arc-shaped gripper 212 is connected to the arc-shaped groove via a connecting slide block, which is driven by an electric slider to slide at a preset angle on the arc-shaped groove. This preset angle is 5 to 10 degrees, used to apply a precise circumferential torsional force to the lens module 100 after axial pressing. This torsional action effectively shears tiny air bubbles and gaps in the adhesive layer, thereby significantly improving the uniformity and density of the adhesive filling, and enhancing the bonding strength and consistency.

[0039] It should be noted that the clamping surface of the arc-shaped gripper 212 is designed to conform to the outer contour of the lens module 100. A layer of polyurethane buffer pad should be adhered to the clamping surface to prevent damage to the module shell and to increase the coefficient of friction to prevent slippage during twisting.

[0040] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The pressing section 22 is responsible for applying radial pressure to the adhesive layer. Specifically, the pressing section 22 includes multiple linear guide grooves formed on the outer ring wall of the arc-shaped support plate 211, and a cover slide 221 that slides up and down on these linear guide grooves via an electric slider. The cover slide 221 includes a semi-circular top plate and a connecting arc plate fixed to the bottom wall of the semi-circular top plate. The connecting arc plate is provided with guide blocks that slide in conjunction with the linear guide grooves, so that the cover slide 221 can slide stably up and down relative to the arc-shaped support plate 211.

[0041] On the side of the two cover slides 221 where the semi-circular top plates are close to each other, interlocking plates 223 are fixed and have mating grooves 224. When the two drive arms 1 are closed, the two semi-circular top plates are interlocked by the interlocking plates 223 and the mating grooves 224 to form a circular top cover structure. On the bottom wall of each semi-circular top plate, that is, the lower surface of the above-mentioned circular top cover structure, an arc-shaped pressing strip 222 is assembled. When the two cover slides 221 are closed, the two arc-shaped pressing strips 222 are joined to form an annular pressing area.

[0042] The arc-shaped pressing strip 222 is preferably made of rubber material with appropriate elasticity, and its cross-section is triangular. In the installed state, the inner ring position of the arc-shaped pressing strip 222 (the position near the axis of the lens module 100) protrudes downward, while the outer ring position (the position near the edge) gradually rises, forming an inclined pressing surface that gradually rises from the inside to the outside.

[0043] When the cover slide 221, together with the arc-shaped pressing strip 222, slides downward relative to the arc-shaped support plate 211, the inclined surface first contacts and presses the inner ring area of ​​the adhesive layer. As the downward pressure continues, the adhesive is gradually pressed from the inner ring of the gap between the lens module 100 and the connector 200 to the outer ring. This radial extrusion method from the inside out helps to expel residual air and guides the adhesive away from the optical center of the lens, effectively reducing the risk of adhesive overflowing into the optical area and creating favorable conditions for subsequent external cleaning of excess adhesive.

[0044] It should be noted that the rubber material of the curved pressing strip 222 should be nitrile rubber or fluororubber, with a Shore A hardness controlled at 50±5 degrees. If it is too soft, the pressing effect will be poor; if it is too hard, it may scratch the surface of the connecting seat 200. The pressing depth should be such that the rubber layer is compressed to 50% to 70% of its original thickness. In addition, the curved pressing strip 222 is designed with a quick-replacement structure so that it can be replaced after a period of production to ensure the consistency of the pressing effect.

[0045] It should be noted that the arc-shaped gripper 212 and the connecting slide are slidably connected up and down by a spring (not shown in the figure), and the arc-shaped gripper 212 and the connecting slide are provided with a locking protrusion (not shown in the figure) driven by an electric slider. When the above-mentioned circumferential torsion action is performed, the locking protrusion locks and fixes the position between the arc-shaped gripper 212 and the connecting slide; when the above-mentioned radial pressing action is performed, the locking protrusion unlocks the position lock between the arc-shaped gripper 212 and the connecting slide, and the arc-shaped gripper 212 and the connecting slide are in a free up and down moving state.

[0046] Through the coordinated action of the clamping part 21 and the pressing part 22, the device of this embodiment achieves a triple action of axial pressing, circumferential torsion and radial pressing of the adhesive layer.

[0047] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the clamping assembly 2 is also provided with an auxiliary mechanism 3. The auxiliary mechanism 3 mainly includes an arc-shaped slide rail formed on the bottom wall of the arc-shaped support plate 211, and a glue removal part 31 slidably connected to the arc-shaped slide rail via an electric slider. There are two glue removal parts 31, and the two glue removal parts 31 are staggered. Each glue removal part 31 is configured to slide half a circle along the arc-shaped slide rail. The two glue removal parts 31 work together to complete the removal of excess glue in a 360-degree range around the joint, and maintain symmetrical movement during the sliding process to improve the stability and balance of the equipment.

[0048] The adhesive removal unit 31 includes a mounting housing 311, inside which a feed roller 312 and a take-up roller 313 are rotatably connected. The take-up roller 313 is actively driven to rotate by a small motor (not shown), while the feed roller 312 is rotatably connected to the mounting housing 311 via a torsion spring (not shown), thereby providing appropriate tension to unused adhesive removal tape 315. Adhesive removal tape 315 is wound onto the feed roller 312 and the take-up roller 313. The feed roller 312 winds clean, unused adhesive removal tape 315, while the take-up roller 313 is used to wind up used adhesive removal tape 315 with adhesive residue.

[0049] A triangular guide 314 is also fixedly mounted on the mounting housing 311. The position of the tip of the guide 314 determines the contact line between the adhesive removal tape 315 and the workpiece surface. Adhesive removal is performed immediately after the pressing action. As the adhesive removal section 31 slides along the arc-shaped slide rail, the guide 314 keeps the adhesive removal tape 315 tangential to the mating point between the lens module 100 and the connecting seat 200, ensuring that the section of adhesive removal tape 315 in contact with the excess adhesive is always a clean, unused area just delivered from the unloading roller 312. The adhesive-laden adhesive removal tape 315 is continuously wound onto the take-up roller 313, thus leaving the mating area and effectively preventing excess adhesive from contaminating the outer wall of the lens module and surrounding components.

[0050] It should be noted that the adhesive strip 315 should be made of PET substrate, and its width should be slightly larger than the width of the overflow area (generally 3mm to 5mm), with a thickness controlled between 0.05mm and 0.10mm to ensure good adhesion to the curved surface. The contact pressure should be controlled within the range of 0.5N to 2.0N. Insufficient pressure (<0.5N) will result in incomplete adhesive removal and residue; while excessive pressure (>2.0N) may scratch the workpiece surface or cause excessive deformation of the adhesive strip. The tangential angle between the guide and the mating point should be maintained between 15 and 30 degrees. An adhesive strip depletion detection sensor, such as a photoelectric transmission sensor, can also be installed inside the mounting housing 311. When the adhesive strip 315 on the feeding roller 312 is about to run out, an alarm signal will be issued to remind the operator to replace it.

[0051] The illumination unit 32 is disposed on the adhesive removal unit 31 and located behind the movement trajectory of the adhesive removal unit 31. In this embodiment, the illumination unit 32 includes a light shield 321 fixedly connected to the mounting housing 311 and a curing lamp 322 mounted on the mounting housing 311. The light shield 321 is used to frame the light source of the curing lamp 322 within a small illumination area to prevent light scattering from affecting the surrounding area.

[0052] The illumination unit 32 moves synchronously with the adhesive removal unit 31, and is configured to provide "instant" spot curing of the adhesive already removed by the adhesive removal unit 31. As soon as the guide member 314 of the adhesive removal unit 31 scrapes away excess adhesive from a small arc length, the curing lamp 322 of the illumination unit 32 immediately provides short-duration, low-energy ultraviolet pre-curing of the adhesive in that area. This quickly locks in the outer edge of the adhesive layer, preventing further adhesive overflow from the freshly cleaned edges due to adhesive flow, and simultaneously laying a stable foundation for subsequent complete curing.

[0053] It should be noted that the curing lamp 322 should use a UV-LED light source, and the single irradiation time should be controlled between 0.5 and 1.5 seconds to ensure that the surface of the adhesive reaches a gel state rather than being completely cured.

[0054] The specific operating steps of this optical lens processing clamping device are as follows: Clamping: The two drive arms 1 approach each other, and the arc-shaped gripper 212 moves to stably clamp the lens module 100 from the outer periphery. At the same time, it drives the two arc-shaped support plates 211 to connect and combine with the slots 214 through the connectors 213 to form a ring-shaped stable structure. After clamping, the lens module 100 is transferred to the area above the connecting seat 200.

[0055] Axial pressing: The vertical drive module of the drive arm 1 moves, causing the entire clamping assembly 2 and the clamped lens module 100 to move downward, pressing the lens module 100 onto the connector 200 which has been pre-coated with an annular adhesive layer, thus achieving the initial compression of the adhesive layer.

[0056] Circumferential torsion: While maintaining axial pressure, the arc-shaped gripper 212 slides 5 to 10 degrees on the arc-shaped groove, applying a small circumferential torsion force to the lens module 100, shearing the adhesive layer to expel air bubbles and fill gaps.

[0057] Radial pressing: The cover slide 221 slides downward relative to the arc support plate 211, driving the arc pressing strip 222 with a triangular cross section to radially press the glue from the inner ring to the outer ring, pushing the glue to the outer area and further compacting the glue layer.

[0058] Adhesive Removal and Pre-curing: After the pressing, twisting, and rolling actions are completed, the two adhesive removal sections 31 begin to slide symmetrically along the arc-shaped slide rail. The guide 314 of each adhesive removal section 31 guides the clean adhesive removal tape 315 to make tangential contact with the outer ring of the joint. The rotation of the take-up roller 313 adheres to and winds up the overflowing adhesive. Immediately afterwards, the curing lamp 322 of the illumination section 32 performs targeted pre-curing on the cleaned area.

[0059] Reset: After completing a full circle of de-adhesive removal and pre-curing, the two drive arms 1 move away from each other, all components are reset, and the assembly of the lens module 100 and connector 200 that has been initially bonded can be removed and sent to the subsequent production steps for deep curing.
