Description

Technical Field

[0001] This utility model relates to the field of eyeglasses manufacturing technology, specifically to a smart eyeglasses temple lower shell adhesive positioning fixture. Background Technology

[0002] In the manufacturing process of eyeglasses, especially high-end smart glasses, it is often necessary to apply adhesive to specific areas of the temples to secure electronic components or structural parts. Traditional adhesive application methods mostly use general-purpose clamps or manual fixation, which have the following drawbacks: Firstly, in the dispensing process, the temples of eyeglasses have complex shapes, especially the head near the hinge and the slender tail, making it difficult for general-purpose fixtures to achieve stable and precise clamping. This can easily lead to inaccurate dispensing positions, affecting product quality and consistency. Secondly, different styles (such as square and round) have different temple shapes, typically requiring different fixtures, increasing equipment costs and management complexity. Furthermore, manual fixing or cumbersome fixture operations reduce uptime (UPH) and can easily damage products due to improper handling.

[0003] Secondly, for temples with long, narrow bottom covers, the adhesive shrinks during the curing process after application. This shrinkage generates internal stress, causing slight warping or deformation (micro-shrinkage) between the bonded temple and the bottom cover, severely affecting the flatness and final quality of the product. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent eyeglass temple lower shell adhesive dispensing and positioning fixture, which can achieve rapid, accurate positioning and stable clamping of the long strip bottom cover of the temple, defining the shape of both ends and the middle until the adhesive cures, effectively improving the quality and efficiency of the dispensing operation.

[0005] The technical solution adopted to solve the above problems is: A smart glasses temple lower shell adhesive dispensing positioning fixture is proposed, comprising: A jig base, on which a carrier is provided, and on which at least one contour groove is provided, the contour groove being compatible with fixing two different shapes of temples: square and round. A head positioning and clamping mechanism is disposed at one end of the fixture base near the head of the temple. The head positioning and clamping mechanism includes a movable head clamping block and a reference block. The reference block is used to contact and position the head end face of the temple, and the head clamping block is used to clamp the head of the temple. The tail adaptive clamping mechanism is located at the other end of the fixture base and is used to clamp the tail of the temple. The tail adaptive clamping mechanism includes dual pressure heads that can operate independently or in conjunction with each other to adapt to the dimensional tolerance of the temple.

[0006] Furthermore, the carrier has two contour grooves, and the two contour grooves are distributed in a figure-eight shape, so that the heads of the two temples placed in the contour grooves are separated and the tails are brought together.

[0007] Furthermore, the two side walls of the contour groove are distributed with a single-sided gap with the temple, and the bottom of the contour groove conforms to the temple.

[0008] Furthermore, the head positioning and pressing mechanism also includes a pressure head fixing seat and a first rotating shaft; the pressure head fixing seat is fixed on the fixture base; the first rotating shaft is fixed on the pressure head fixing seat, the head pressing block has an overall "Z" shaped structure, and a first shaft hole is opened at its lower end bend, the first rotating shaft passes through the first shaft hole, so that the head pressing block can rotate around the first rotating shaft to realize the pressing or releasing action; a first return spring is provided between the pressure head fixing seat and the head pressing block, the first return spring keeps the head pressing block in a pressed state when it is not subjected to external force.

[0009] Furthermore, the head positioning and pressing mechanism also includes a first rotating block, a first bearing seat, and a first handle; the first bearing seat is fixed on the pressing head fixing seat, the middle part of the first rotating block is a circular shaft and is installed on the first bearing seat, one end of the first rotating block is fixedly connected to the first handle, and the other end of the first rotating block is located in the enclosed area of ​​the head pressing block and is provided with an eccentric blocking part.

[0012] Furthermore, the dual pressure head has two push blocks, each push block corresponding to the tail of a temple, and a gasket is provided between the two push blocks.

[0013] Furthermore, the gasket is a nylon gasket. The nylon gasket is used to reduce friction during the relative movement of the two pressure heads, making their operation smoother.

Detailed Implementation

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to this utility model are shown in the drawings, not the entire structure.

[0019] In the description of this utility model, 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 utility model based on the specific circumstances.

[0020] 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.

[0021] 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] Please see Figure 1-8 This embodiment proposes a smart eyeglass temple lower shell adhesive dispensing and positioning fixture, including a fixture base 1, a head positioning and clamping mechanism 2, and a tail adaptive clamping mechanism 3. The fixture base 1 is provided with a carrier 4, which has two contouring grooves. Each contouring groove can accommodate both square and round temple shapes. The two contouring grooves are arranged in a figure-eight shape, so that the heads of the two temples placed on them are separated, while the tails are converged.

[0023] Once the temples are placed in the contour groove, the two side walls of the groove limit the movement of the temples on both sides, with a single-sided gap of less than 1mm, preferably 0.075mm. The bottom of the contour groove conforms to the contour, ensuring the temples are placed stably within the groove. If necessary, anti-slip textures can be added to further enhance the stability of the temples within the contour groove.

[0024] There are two sets of head positioning and clamping mechanisms 2, which are set at one end of the fixture base 1. Each set of head positioning and clamping mechanisms 2 corresponds to the head of one temple. The head positioning and clamping mechanism 2 includes a movable head pressing block 21 and a reference block 22. The reference block 22 is used to contact and position the end face of the temple head, and the head pressing block 21 is used to clamp the temple head to prevent the temple head from shaking during the subsequent glue dispensing process.

[0025] One set of tail-adaptive clamping mechanisms 3 is located at the other end of the fixture base 1 and is used to clamp the tail of the temple. The tail-adaptive clamping mechanism includes dual clamping heads 31 that can operate independently or in conjunction with each other. The "dual clamping head" design is used to address the manufacturing tolerances of the temples, ensuring that the tails of temples of different sizes can be reliably clamped, avoiding the problem of insufficient clamping that may occur with a single clamping head, and improving the versatility and stability of the entire dispensing fixture.

[0026] Specifically, combined Figure 7 , Figure 8 As shown, the head positioning and clamping mechanism 2 also includes a pressure head fixing seat 23, which is fixed to the fixture base 1 by bolts, providing reliable support for the entire head positioning and clamping structure 2. A first rotating shaft 24 is provided on the pressure head fixing seat 23.

[0027] The head pressure block 21 has a Z-shaped structure, with a first shaft hole at its lower bend. A first rotating shaft 24 passes through the first shaft hole, allowing the head pressure block 21 to rotate on the first rotating shaft 24. When the first rotating shaft 24 rotates, it drives the head pressure block 21 to move synchronously. A first return spring 25 is provided between the pressure head fixing seat 23 and the head pressure block 21. The first return spring 25 ensures that the head pressure block 21 remains in a pressed state when not subjected to other external forces, ensuring stable pressing of the temple head and preventing pressing failure due to unexpected situations.

[0028] To further optimize the user experience and facilitate on-site operations, a first rotating block 26 is also provided on the pressure head fixing seat 23. The first rotating block 26 has a circular shaft in the middle, which is installed on the first bearing seat 27. One end is fixedly connected to the first handle 28, and the other end is located in the area enclosed by the head pressure block 21 and has an eccentric abutment.

[0029] On-site personnel can quickly change the rotation angle of the first rotating block 26 by turning the first handle 28. When the first rotating block 26 rotates, the eccentric stop part presses against the head block 21, which can overcome the elastic force of the first return spring 25 and make the head block 21 press down; turning the first handle 28 in the opposite direction will reset the first return spring 25, pushing the head block 21 upward to release it. The operation is convenient and efficient, greatly improving the convenience of on-site operations.

[0030] In this design, the reference block 22 and the head pressure block 21 are made of antistatic black PEEK material, which can also be replaced with polyimide material with similar antistatic and mechanical properties. The spring constant of the first return spring 25 is in the range of 1.4-1.6 N / mm, preferably 1.5 N / mm.

[0031] Combination Figure 5 , Figure 6 As shown, the tail adaptive clamping mechanism 3 includes a tail fixing seat 32, which is fixed to the fixture base 1 by bolts, providing reliable support for the entire tail adaptive clamping mechanism 3. A second rotating shaft 33 is provided on the tail fixing seat 32.

[0032] The double pressure head 31 has an overall "L" shape structure, with a second shaft hole in the middle. The second rotating shaft 33 passes through the second shaft hole, so that the double pressure head 31 rotates on the second rotating shaft 33.

[0033] When the second rotating shaft 33 rotates, it drives the double pressure head 31 to move synchronously. The second return spring 34 installed between the double pressure head 31 and the tail fixing seat 32 ensures that the double pressure head 31 remains in the pressed state when it is not subjected to other external forces, thus ensuring stable pressing of the tail of the temple and preventing pressing failure due to unexpected situations.

[0034] To further optimize the user experience and facilitate on-site operations, a second rotating block 35 is also provided on the tail fixing seat 32. The second rotating block 35 has a circular shaft in the middle, which is mounted on the second bearing seat 36. One end is fixedly connected to the second handle 37, and the other end is located in the area enclosed by the tail fixing seat 32 and the double pressure head 31 and has an eccentric abutment.

[0035] By turning the second handle 37, the operator can quickly change the rotation angle of the second rotating block 35. When the second rotating block 35 rotates, the eccentric stop presses against the lower end of the double pressure head 31, overcoming the elastic force of the second return spring 34 and causing the upper pressing part of the double pressure head 31 to press down. Turning the second handle 37 in the opposite direction resets the second return spring 34, pushing the double pressure head 31 upward to release it. The operation is convenient and efficient, greatly improving the convenience of on-site operations.

[0036] Similarly, the dual pressure heads are also made of anti-static black PEEK material, and the second return spring 34 has an elastic coefficient of 7.5 N / mm to prevent shaking.

[0037] In this design, the dual pressure head 31 adopts a dual push block structure, with each push block corresponding to a different temple. A 0.2 mm thick shim is added between the two push blocks. The shim is made of nylon, which effectively reduces friction during the relative movement of the dual pressure heads 31, making the movement smoother.

[0038] To improve the ease of handling the dispensing fixture, handles 5 are provided on both sides of the fixture base 1. The handles 5 have anti-slip textures to increase friction and facilitate gripping. Additionally, bushings 11, reinforcing buckles 12, and magnets 13 are symmetrically distributed on both sides of the fixture base 1. This structural design enhances the practicality of the dispensing fixture assembly and its stability during use.

[0039] This invention offers significant advantages through the coordinated operation of the head positioning and clamping mechanism 2, the tail adaptive clamping mechanism 3, and the contouring groove on the carrier 4. The head clamping block 21 and the reference block 22 of the head positioning and clamping mechanism 2 precisely position and clamp the temple head; the double clamping heads 31 of the tail adaptive clamping mechanism 3 can adaptively adjust according to the temple manufacturing tolerances, reliably clamping the tail. The contouring groove on the carrier 4, with its unique shape and size design, can stably accommodate temples of different shapes. The three mechanisms work together to efficiently position and clamp both ends of the temple within the contouring groove, providing stable conditions for subsequent automatic glue dispensing at preset positions on the temple. After glue dispensing, the elongated temple lower shell 6 is installed until the glue is fixed before removing the finished product. This avoids micro-shrinkage deformation between the temple lower shell 6 and the temple caused by glue shrinkage. Operators can quickly remove the temple with simple operations, such as turning the first handle 28 to release the head clamping block 21. The fixture immediately returns to its initial state, requiring no complex adjustments, and can quickly be put into the next cycle, greatly improving production efficiency and reducing operational difficulty and time costs.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
