Description

Technical Field

[0001] This invention relates to the field of smart glasses assembly and UV curing equipment technology, and in particular to a UV curing device for the front and rear frames of smart glasses, used for positioning and pressing the front and rear frames and for UV curing the side joints of the two frames. Background Technology

[0002] The frames of smart glasses are typically composed of a front frame and a rear frame. During assembly, UV adhesive is applied to the mating surfaces or seams of the two frames, and then cured by ultraviolet light. Because the frame itself is an irregularly shaped, thin-walled structure with double lens rings, a bridge, and hinge frames on both sides, the front and rear frames are prone to misalignment, warping, or uneven gaps during molding. This is especially true in the hinge frame area, where thickness and contour variations are significant. Without stable lateral constraints, misalignment, delamination, or poor appearance can easily occur after curing. Existing general-purpose fixtures can only provide simple support or point pressure for the frames, making it difficult to simultaneously achieve contour positioning, uniform pressing, locking of the hinge frames at both ends, and directional exposure of the seam area. Furthermore, manual transfer to the UV lamp may damage the uncured assembly, resulting in low product consistency and production efficiency. Therefore, a specialized device is needed that adapts to the front and rear frame structure of smart glasses and can work in conjunction with a UV irradiation mechanism. Summary of the Invention

[0003] The purpose of this invention is to provide a smart eyeglasses front and rear frame UV curing device to solve the problems of insufficient positioning accuracy, unstable pressing state, easy loosening of the hinge frame area, and difficulty in quickly and evenly implementing UV curing on the side splicing seams when the front and rear frames are molded together. The device enables the frames to complete automatic feeding and contour irradiation in the positioning, pressing and lateral locking states, thereby improving the consistency of assembly quality and product yield.

[0004] The technical solution adopted to solve the above problems is:

[0005] A smart eyeglass frame UV curing device is proposed, comprising a UV curing chamber, a worktable, a frame, a UV lamp irradiation module, an eyeglass frame pressing and assembly fixture, a feed drawer, and a forward feeding assembly. The worktable is disposed inside the UV curing chamber, the frame and the feed drawer are disposed on the worktable, the eyeglass frame pressing and assembly fixture is supported by the feed drawer, the UV lamp irradiation module is connected to the frame and is disposed facing the curing station of the eyeglass frame pressing and assembly fixture, and the forward feeding assembly is used to drive at least one of the UV lamp irradiation modules to enter or exit the curing station; the UV lamp irradiation module includes a UV lamp and a UV lamp mounted on the UV lamp. The ultraviolet lamp emits light from a simulated eyeglass frame projection port, which extends along the side seam contour of the front and rear eyeglass frames in the molded state. The eyeglass frame pressing assembly fixture includes a rear eyeglass frame positioning platform, a front eyeglass frame positioning platform, a front eyeglass frame pressing platform, and an eyeglass frame locking platform that fit together from bottom to top. The rear eyeglass frame positioning platform is used to support the rear eyeglass frame in a contoured manner. The front eyeglass frame positioning platform is used to position the front eyeglass frame and align it with the rear eyeglass frame. The front eyeglass frame pressing platform is used to apply a pressing force to the front eyeglass frame toward the rear eyeglass frame. The eyeglass frame locking platform is used to maintain the pressing force. The eyeglass frame pressing assembly fixture also has side elbow clamp assemblies on both sides for laterally pressing the hinge frame.

[0006] Furthermore, the UV lamp irradiation module is configured as two sets arranged vertically opposite each other. The upper UV lamp is connected to a lifting cylinder mounted on the frame. The lifting cylinder drives the upper UV lamp to extend downwards, so that its simulated eyeglass frame projection port is flush with the side seam of the front and rear eyeglass frames in the height direction. The lower UV lamp is connected to the forward feeding component, which feeds it horizontally into or out of the side of the eyeglass frame pressing assembly fixture. After the two sets of UV lamps reach the irradiation position, they are distributed on the front and rear sides of the pressed eyeglass frame.

[0007] Furthermore, the forward feeding assembly includes a feeding cylinder and a cooperating feeding slider rail. The lower UV lamp is guided by the feeding slider rail, and the feeding cylinder provides linear feeding power, allowing the lower UV lamp to switch between a retracted position for avoiding loading and unloading and an irradiation position on the side of the eyeglass frame pressing assembly fixture. During curing, the two sets of UV lamps on the front and rear sides are turned on simultaneously, allowing the UV light to irradiate the side seam through the corresponding simulated eyeglass frame projection port until the adhesive cures.

[0008] Furthermore, the rear mirror frame positioning platform includes a lower base and a rear mirror frame contour block disposed on the lower base. The rear mirror frame contour block has a supporting and positioning surface that matches the inner contour of the rear mirror frame. The lower base is provided with a mirror frame locking block for engaging with a clamping latch on the mirror frame locking platform, so that each platform body is kept in a locked state with the front mirror frame and the rear mirror frame.

[0009] Furthermore, the front frame positioning platform includes an upper base, an elastic latch, a frame latch, and a nose bridge limiting block; the frame latch is distributed around the lens rim and near the hinge frame of the front frame, and is used to releasably hold the front frame under the upper base; the nose bridge limiting block cooperates with the nose bridge area of ​​the front frame to limit lateral movement; the upper base is provided with a guide rod bushing and a positioning bushing, which are respectively used to receive the guide and positioning components of the front frame pressing platform.

[0010] Furthermore, the front mirror frame pressing platform includes a pressing plate, an auxiliary positioning pin, a main positioning pin, a nose bridge spring pressing block, and a long positioning guide rod; the long positioning guide rod slides in conjunction with the guide rod bushing, the main positioning pin inserts into the positioning bushing, and the auxiliary positioning pin engages with a corresponding positioning part on the front mirror frame positioning platform to establish multi-point guidance and anti-rotation positioning; the nose bridge spring pressing block provides elastic pressing force to the nose bridge area; the pressing plate is provided with an inclined locking block, which engages with the elastic lock buckle, allowing the front mirror frame pressing platform and the front mirror frame positioning platform to be quickly assembled and released.

[0011] Furthermore, the frame locking platform includes a pressure plate and multiple elastic pressure columns. The elastic pressure columns are disposed between the pressure plate and the front frame pressing platform to elastically distribute the locking load to the pressing plate, compensate for minor differences in the frame contour, adhesive layer thickness and assembly dimensions, and avoid rigid concentrated force that could cause frame deformation.

[0012] Furthermore, the clamping lock includes a long locking rod, a clamping hook, and a hinge seat. The long locking rod is hinged to the frame locking platform or the front frame pressing platform through the hinge seat. The clamping hook is located at the lower end of the long locking rod. When the long locking rod is rotated to the locking position, the clamping hook engages with the frame locking block on the lower base and pulls the upper platform downward to maintain the mold closing pressure of the front frame and the rear frame.

[0013] Furthermore, the side elbow clamp assembly includes a side pressure arm, a side pressure block, and an elbow clamp. The elbow clamp drives the side pressure arm to swing. The side pressure block is disposed at the pressure end of the side pressure arm and corresponds to the spliced ​​hinge frame front shell and hinge frame rear shell. After the elbow clamp passes the locking position, it maintains the lateral pressure of the side pressure block to constrain the relative position of the hinge frame front shell and the hinge frame rear shell.

[0014] Furthermore, the device also includes a UV lamp controller electrically connected to the UV lamp and a barcode scanner for reading product or work order information. The UV lamp controller is used to set the irradiation time or output status, and the barcode scanner is used to associate the information of the eyeglass frame to be processed. The feed drawer is used to send the eyeglass frame pressing assembly fixture from the loading and unloading position into the curing position in the UV curing chamber, thereby separating the loading and unloading operation from the UV irradiation area.

[0015] The beneficial effects of the technical solution of this invention are:

[0016] 1. The UV curing equipment for the front and rear frames of the smart glasses uses a rear frame contour support, a front frame suspension and positioning, a guide rod and positioning pin combined guidance, and a nose bridge area limit to enable the front and rear frames to accurately align in a predetermined posture, reducing misalignment at the lens ring, nose bridge, and hinge frame.

[0017] 2. A continuous pressing force is formed by the front frame pressing platform, the frame locking platform, the elastic pressure column and the clamping buckle, and the elastic components are used to compensate for the differences in size and adhesive layer, so that the joint gap is uniform and does not easily rebound before the adhesive cures.

[0018] 3. The hinge frame front shell and hinge frame rear shell are pressed together by the side elbow clamp components on both sides, which improves the fitting quality of the thick wall area at the end of the frame.

[0019] 4. The light-emitting port of the simulated eyeglass frame is flush with the side seam of the eyeglass frame in the height direction, and forms a directional light-emitting area according to the outline of the seam, which can concentrate ultraviolet energy on the seam where the glue is located;

[0020] 5. The combination of upper lifting and lower horizontal feeding can create clearance space during loading and unloading, and during curing, two sets of UV lamps are distributed on the front and back sides of the frame and simultaneously irradiate the seam, reducing obstruction and improving curing uniformity.

[0021] 6. The feed drawer, cylinder drive, and barcode scanning are linked to facilitate rhythmic operation, avoid posture changes caused by manual handling and irradiation, and improve production efficiency, quality consistency, and product yield. Attached Figure Description

Detailed Implementation

[0035] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figures 1 to 4 As shown, this equipment includes a UV curing chamber 1, a UV lamp controller 2, a barcode scanner 3, a worktable 4, a frame 5, a lifting cylinder 6, a UV lamp 7, a spectacle frame pressing and assembly fixture 8, a feed drawer 9, and a forward feeding assembly 10. The UV curing chamber 1 forms a relatively enclosed irradiation space. Its front can be equipped with an operating interface, start / stop mechanism, emergency stop mechanism, and protective door to reduce UV light leakage. The UV lamp controller 2 is electrically connected to the UV lamp 7 and is used to control start / stop, irradiation time, and output status. The barcode scanner 3 is used to read the identification information of the spectacle frame, fixture, or work order, associating the processing parameters with the product to be processed.

[0040] The workbench 4 is installed inside the UV curing chamber 1, and the frame 5 is vertically fixed on the workbench 4. The feed drawer 9 can move relative to the workbench 4 between the loading / unloading position outside the chamber and the curing position inside the chamber. The eyeglass frame pressing and assembly fixture 8 is positioned and installed in the feed drawer 9 so that the entire assembly can be fed into or out of the irradiation area. The feed drawer 9 can be equipped with a positioning detection device and forms a safety interlock with the UV lamp 7. Irradiation is only allowed after the feed drawer 9 reaches the curing position and the protective door is closed.

[0041] In this embodiment, the UV lamps 7 are arranged in two sets, one above the other.

[0042] The upper UV lamp 7 is connected to the output end of the lifting cylinder 6, which is mounted on the frame 5. The lifting cylinder 6 drives the upper UV lamp 7 from its rising and clearance position downwards into the irradiation position until its mirror-like projection port 701 is flush with the side seam of the front mirror frame 12 and the rear mirror frame 11 in the height direction. It should be noted that: flush means that the effective light output height of the mirror-like projection port 701 corresponds to the height of the seam, and does not require the lamp body to be in contact with the mirror frame.

[0043] The lower UV lamp 7 is mounted on the forward feeding assembly 10. The forward feeding assembly 10 includes a feed cylinder 1001 and a feed slider rail 1002. The feed cylinder 1001 drives the lower UV lamp 7 to move along the feed slider rail 1002 to the side or retracted position of the eyeglass frame pressing assembly fixture 8.

[0044] Both sets of UV lamps 7 have frame-like light-emitting ports 701 on their light-emitting sides. The extended contour of the frame-like light-emitting ports 701 is the same as or matches the contour of the side seam after the front frame 12 and the rear frame 11 are molded together. It can form a continuous or segmented light-transmitting area around the left and right lens rings, the nose bridge 1202 of the frame, and the hinge frames on both sides. The light emission of the remaining areas is restricted by the light-shielding structure. After the two sets of UV lamps 7 reach the irradiation position, they are distributed on the front and rear sides of the pressed frame, and the corresponding frame-like light-emitting ports 701 face the side seam. When the UV lamps 7 on the front and rear sides are turned on at the same time, UV irradiation can be carried out on the seam from opposite directions until the glue cures.

[0045] like Figure 5 and Figure 6 As shown, the eyeglass frame pressing and assembly fixture 8 includes a rear frame positioning platform 801, a front frame positioning platform 802, a front frame pressing platform 803, and a frame locking platform 804, which fit together from bottom to top. It also includes a clamping lock 805 and a side elbow clamp assembly 806. The rear frame positioning platform 801 includes a lower base 8011 and a rear frame contour block 8012. The rear frame contour block 8012 is fixed on the lower base 8011 and has a supporting and positioning surface that matches the inner contour of the rear frame 11, used to restrict the translation, rotation, and sinking of the rear frame 11. Hinge frame rear shells 1101 are formed on both sides of the rear frame 11, and the rear frame contour block 8012 is provided with corresponding supporting or abutment parts near the hinge frame rear shells 1101. The lower base 8011 has a frame locking block 80111 on its edge, and the frame locking block 80111 has a locking part for the buckle 805 to be engaged.

[0046] like Figure 7 and Figure 8As shown, the front frame positioning platform 802 includes an upper base 8021, elastic latches 8022, frame latches 8023, and a nose bridge limiting block 8024. The upper base 8021 has clearance areas corresponding to the left and right lens rings. Multiple frame latches 8023 are distributed around the lens rings and near the hinge frames, releasably holding the front frame 12 under the upper base 8021. The hinge frame front shells 1201 on both sides of the front frame 12 are limited by the corresponding frame latches 8023. The nose bridge 1202 of the frame cooperates with the nose bridge limiting block 8024 to determine the lateral and center positions of the front frame 12. The upper base 8021 is provided with a guide rod bushing 80211 and a positioning bushing 80212. Elastic latches 8022 are also provided on both sides of the upper base 8021, each with a locking hook 80221 capable of elastic deflection.

[0047] like Figure 9 and Figure 10 As shown, the front frame pressing platform 803 includes a pressing plate 8031, an auxiliary positioning pin 8032, a main positioning pin 8033, a nose bridge spring pressing block 8034, and a long positioning guide rod 8035. The long positioning guide rod 8035 slides with the guide rod bushing 80211, providing long-stroke guidance for the pressing plate 8031; the main positioning pin 8033 is inserted into the positioning bushing 80212, and the auxiliary positioning pin 8032 cooperates with the corresponding positioning part of the upper base 8021, jointly establishing precise positioning and anti-rotation constraint. The nose bridge spring pressing block 8034 faces the nose bridge 1202 of the frame, applying pressure to the nose bridge area within its elastic stroke to compensate for height differences and avoid rigid pressure damage.

[0048] The pressing plate 8031 ​​has inclined locking blocks 80311 on both sides. When the pressing plate 8031 ​​descends, the inclined locking blocks 80311 push the locking hook 80221 outward; after reaching the locking position, the locking hook 80221 resets and engages with the inclined locking blocks 80311 to lock, keeping the front frame pressing platform 803 and the front frame positioning platform 802 in a combined state. The frame locking platform 804 includes a pressure plate 8041 and multiple elastic pressure posts 8042, which are arranged between the pressure plate 8041 and the pressing plate 8031. After the pressure plate 8041 is pressed down, each elastic pressure post 8042 undergoes elastic deformation, distributing the load pressure to the pressing plate 8031 ​​to compensate for the residual size difference of the splicing gaps of the front frame 12, the rear frame 11, and the adhesive layer, so that the pressing force near the left and right lens rings and the bridge of the nose is more balanced.

[0049] The clamping lock 805 includes a long locking rod 8051, a clamping hook 80511, and a hinge seat 8052. The hinge seat 8052 is connected to the pressure plate 8041 or its linkage component. The long locking rod 8051 is rotatably connected to the hinge seat 8052. The clamping hook 80511 is located at the lower end of the long locking rod 8051. When the long locking rod 8051 is rotated to the locked position, the clamping hook 80511 engages with the frame locking block 80111 and pulls the upper platform downward, so that the pressure plate 8041, the pressing plate 8031, the upper base 8021, and the lower base 8011 form an integral locking structure to prevent the frame from springing back or separating before the glue cures.

[0050] like Figure 11 and Figure 12 As shown, the side elbow clamp assembly 806 is respectively disposed at the left and right ends of the fixture, including a side pressure arm 8061, a side pressure block 8062, and an elbow clamp 8063. The elbow clamp 8063 drives the side pressure arm 8061 to swing towards the end of the frame. The side pressure block 8062, disposed at the pressure end of the side pressure arm 8061, corresponds to the spliced ​​hinge frame front shell 1201 and hinge frame rear shell 1101, and presses against the hinge frame front shell 1201 to fit against the hinge frame rear shell 1101. After the elbow clamp 8063 passes the locking position, it remains in a lateral clamping state. The side pressure block 8062 can be made of elastic or non-scratch-resistant material, and its working surface can be adapted to the shape of the spliced ​​hinge frame to increase the constraint area and reduce indentations.

[0051] When this equipment is in operation, first raise the upper UV lamp 7 and retract the lower UV lamp 7, then pull the feed drawer 9 to the loading / unloading position. Place the rear mirror frame 11 on the rear mirror frame contour block 8012; install the front mirror frame 12, which has been coated with UV adhesive, onto the underside of the front mirror frame positioning platform 802, maintaining its posture with the mirror frame latch 8023, and constraining the mirror frame nose bridge 1202 with the nose bridge limiting block 8024. Then align the front mirror frame positioning platform 802 with the rear mirror frame positioning platform 801, so that the front mirror frame 12 and the rear mirror frame 11 are initially assembled.

[0052] Next, install the front mirror frame pressing platform 803, so that the long positioning guide rod 8035 enters the guide rod bushing 80211, the main positioning pin 8033 enters the positioning bushing 80212, and the auxiliary positioning pin 8032 completes auxiliary positioning; continue to press down the pressing plate 8031, so that the locking hook 80221 engages with the inclined locking block 80311, and the nose bridge spring pressure block 8034 and other pressing parts of the pressing plate 8031 ​​work together to act on the front mirror frame 12. After the mirror frame locking platform 804 is pressed down, the elastic pressure column 8042 transmits pressure to the front mirror frame pressing platform 803; then rotate the long locking rod 8051 so that the clamping locking hook 80511 latches the mirror frame locking block 80111. Finally, operate the left and right elbow clamps 8063 so that the side pressure blocks 8062 press the hinge frame front shell 1201 and hinge frame rear shell 1101 at both ends respectively, completing the longitudinal pressing and lateral locking.

[0053] After locking, the product information is read by the barcode scanner 3 and the parameters of the UV lamp controller 2 are called, pushing the feed drawer 9 into the UV curing chamber 1. The lifting cylinder 6 drives the upper UV lamp 7 to descend until its mirror frame projection port 701 is flush with the side seam of the front mirror frame 12 and the rear mirror frame 11; the feed cylinder 1001 drives the lower UV lamp 7 to enter the side of the eyeglass frame pressing assembly fixture 8 along the feed slider rail 1002. After the two sets of UV lamps 7 are in place and distributed on the front and rear sides of the pressed mirror frame, the front and rear UV lamps 7 are turned on simultaneously, and UV irradiation is continuously applied to the joint until the glue cures. During the irradiation process, the contour positioning, elastic pressing, and side pressure at both ends remain unchanged.

[0054] After irradiation, turn off the UV lamp 7. The upper UV lamp 7 rises, and the lower UV lamp 7 retracts. Then move the feed drawer 9 to the loading / unloading position. Release the elbow clamp 8063, the clamping lock 805, and the elastic lock 8022 in sequence. Remove the frame locking platform 804 and the front frame pressing platform 803, and release the frame lock 8023. The cured front frame 12 and rear frame 11 can then be removed. Because the frame is constantly subjected to contour support, longitudinal pressing, and lateral clamping at the ends during the irradiation stage, the cured frame can maintain a relatively uniform seam.

[0055] In other embodiments, the lifting cylinder 6 or the feed cylinder 1001 can be replaced by an electric push rod, a lead screw module, or other linear drive mechanism; the mirror frame projection port 701 can be formed by a replaceable light shield to adapt to different models of mirror frames; the mirror frame pressing assembly fixture 8 can also be connected to the feed drawer 9 via a quick-change base plate. Any equivalent structure that employs contour positioning and continuous locking of the front and rear mirror frames, and directional curing of UV light along the splicing seam, can be applied to this invention.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the claims of the present invention.
