Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, specifically to a lens temple adhesive dispensing fixture. Background Technology

[0002] With the rapid development of smart wearable devices, smart glasses temples are increasingly integrating electronic components such as chips and sensors (e.g., positioning modules or health monitoring sensors in AR glasses). These components require temple cover plates for sealing and signal transmission. The adhesive application process is crucial in this scenario—adhesive must be precisely applied along the temple edge to bond the cover plate to the temple. This process must ensure a tight seal while preventing adhesive overflow that could obstruct the optical window or circuit interfaces. Such processes place stringent requirements on the positioning accuracy of the fixture, resistance to electrostatic interference, and adaptability to complex environments, especially in high-end applications such as medical and outdoor applications.

[0003] Currently, most clamps used for dispensing adhesive on eyeglass temples are made of metal or acetal alloy, with rigid positioning grooves formed by CNC machining. The chip embedded area in the temple is usually a brittle PCB board or glass substrate. Metal clamps are prone to micro-cracks due to rigid contact during clamping, or scratches on high-gloss and electroplated products due to rigid contact, resulting in defects and increased production costs. To avoid interference, rigid clamps need to enlarge the tolerance of the temple groove, which leads to inaccurate positioning during placement or easy movement of the temple during dispensing, resulting in uneven adhesive layer thickness after dispensing. Furthermore, when used in high humidity environments, metal clamps are also prone to rust, requiring frequent polishing or maintenance, which increases production and usage costs. Utility Model Content

[0004] The purpose of this invention is to provide a temple adhesive dispensing fixture that avoids hard friction, thereby preventing surface scratches, maintaining dispensing accuracy while preventing the temple from shifting due to vibration during the dispensing process, and reducing usage costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a temple adhesive clamp, including a silicone clamp body and a clamping slot for placing the temple;

[0007] The surface of the silicone clip is at least partially arc-shaped, and the two top arc portions of the arc surface are spaced apart along a first direction.

[0008] The clamping groove is formed on the surface of the silicone clamp body and extends along the first direction. The clamping groove at least partially coincides with the arc surface portion of the silicone clamp body projected along the second direction. The inner sidewall of the clamping groove is provided with a plurality of rectangular grooves at equal intervals along the circumference.

[0009] Optionally, the inner bottom wall of the rectangular groove has a slope that gradually rises away from the direction of the clamp groove.

[0010] Optionally, it also includes a clamp base, which is detachably connected to the silicone clamp via a positioning component.

[0011] Optionally, the positioning component includes a positioning block formed on the fixture seat, and the silicone clamp has a positioning hole corresponding to the positioning block, and the silicone clamp is slidably connected to the positioning block through the positioning hole.

[0012] Optionally, the positioning component further includes a storage groove formed on the surface of the clamp seat, a first magnet is fixedly connected to the inner bottom wall of the storage groove, and a second magnet is correspondingly provided on the surface of the silicone clamp facing the storage groove, the second magnet being at least partially located in the storage groove and abutting against the first magnet.

[0013] Optionally, it also includes an inflatable airbag, which is disposed inside the positioning block, and the positioning block has a clearance opening on its surface facing the clamp groove.

[0014] Optionally, the inflatable airbag is provided with a first state and a second state. When the inflatable airbag is in the first state, it is relatively contracted, located inside the positioning block, and does not extend out of the clearance opening. When the inflatable airbag is in the second state, it is relatively extended, and at least part of the inflatable airbag extends out of the clearance opening and abuts against the inner wall of the positioning hole, pushing the positioning hole to cause the fixture groove to deform.

[0015] Optionally, the silicone clips are provided with reinforcing blocks inside both sides of the rectangular groove, and the reinforcing blocks are used to improve the toughness of the rectangular groove.

[0016] This utility model provides a temple adhesive clamp, which has the following beneficial effects:

[0017] This temple adhesive clamp enhances the fit of the silicone clamp to the product through clamping grooves. Specifically, it uses a soft material to elastically deform and wrap the temple, absorbing impact energy and avoiding hard friction, thus preventing surface scratches. Compared to rigid metal clamps, it solves the interference problem between the temple and the clamping groove without increasing tolerances, while maintaining adhesive dispensing accuracy. The surface of the silicone clamp is at least partially curved, which matches the curvature of the temple. When the temple is pressed vertically downwards, it reduces the contact depth between the temple and the silicone clamp, preventing excessive friction that could cause jamming and bending of the temple. It also prevents the temple from being inserted too deeply into the clamping groove, which could deform the silicone clamp and cause the adhesive dispensing position to shift. This is achieved through a rectangular... The grooves allow the rectangular groove sidewalls to passively expand when placing the temples, facilitating rapid placement and removal by robotic arms or manual labor, thereby increasing stability during the dispensing process. The rectangular grooves also serve as temporary storage channels for excess adhesive, preventing adhesive buildup between the temples and the clamping groove walls, reducing the risk of adhesion after curing. When the temples expand due to heat after dispensing, the groove structure of the rectangular grooves allows for localized stretching of the silicone, reducing the probability of overall clamp deformation. The edges of the rectangular grooves provide friction, preventing the temples from shifting due to vibration during dispensing, especially in humid environments where metal clamps are prone to corrosion. After absorbing moisture and corroding, the metal clamps will experience dimensional fluctuations, which can easily lead to temple jamming or dispensing misalignment. Furthermore, the production cost of metal clamps is relatively high, making it difficult to reduce production costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a clamp that is suitable for dispensing adhesive and clamping components for various electronic products. It can prevent scratches on the surface of high-gloss products, thus avoiding defects and greatly improving the yield. Specifically applied to the application scenario of dispensing adhesive on the temples of glasses, it absorbs collision energy through elastic deformation, avoids hard friction, improves the stability of temple clamping, and at the same time avoids scratches on the temples. Specifically, it is a temple dispensing clamp.

[0026] Please see Figures 1 to 5 The present invention provides a technical solution: a temple adhesive clamp, comprising a silicone clamp body 1 and a clamp groove 2 for placing the temple;

[0027] The surface of the silicone clamp 1 is at least partially arc-shaped, and the two top arc portions of the arc surface are spaced apart along a first direction.

[0028] The clamp groove 2 is formed on the surface of the silicone clamp body 1 and extends along the first direction. The clamp groove 2 at least partially coincides with the arc surface portion of the silicone clamp body 1 projected along the second direction. The inner sidewall of the clamp groove 2 is provided with a plurality of rectangular grooves 3 at equal intervals along the circumference.

[0029] The surface of the silicone clamp 1 is at least partially recessed inward along the second direction to form an arc-shaped surface. The two top arcs of the arc-shaped surface are spaced apart along the first direction to match the natural curvature of the temple. This creates a gradual contact when the temple is placed, preventing the clamp groove 2 from being too deep and causing the temple to bend or the silicone clamp 1 to partially obscure the chip area and affect the dispensing. The clamp groove 2 extends along the first direction and coincides with the projection of the arc-shaped surface in the second direction (tem height direction), ensuring that the temple edge is aligned with the dispensing path. The inner sidewall of the clamp groove 2 is provided with multiple rectangular grooves 3 that are circumferentially equidistant. When the temple is inserted, the sidewall of the rectangular groove 3 can expand outward to compensate for the temple width and will not affect the dispensing accuracy. When the dispensing pressure fluctuates, excess glue flows into the rectangular groove 3 for temporary storage, preventing the glue layer from overflowing and affecting the removal of the temple. When changes in ambient temperature and humidity cause the temple to expand, the rectangular groove 3 releases local stress to prevent the clamp from twisting as a whole.

[0030] If a rigid material is used for the fixture body, the only way to increase the draft angle of the fixture slot 2 is to increase the angle. If the angle is too large, the product will not be properly secured when placed in the fixture, and the temple or the object being clamped will wobble, thus losing the function of the fixture itself.

[0031] The rectangular groove 3 is designed to accommodate the product's deformation after placement, and its size, depth, and spacing can be arranged in a reasonable manner to ensure that the product is clamped neither too tightly nor too loosely.

[0032] The clamping groove 2 enhances the wrapping effect of the silicone clamp 1 on the product. Specifically, it uses a soft material to elastically deform and wrap the temple, absorbing impact energy through elastic deformation and avoiding hard friction, thus preventing surface scratches. Compared to hard metal clamps, it solves the interference problem between the temple and the clamping groove 2 without increasing tolerances, while maintaining dispensing accuracy. The surface of the silicone clamp 1 is at least partially curved, which can match the curvature of the temple. When the temple is pressed vertically downwards, it reduces the contact depth between the temple and the silicone clamp 1. Excessive contact depth can easily cause jamming due to friction, leading to temple bending. It also prevents the temple from being inserted too deeply into the clamping groove 2, which could deform the silicone clamp 1 and cause dispensing position misalignment. The rectangular groove 3 further enhances this effect. When placing the temples, the sidewalls of the rectangular groove 3 can be passively expanded, adapting to rapid handling by robotic arms or manual labor, thereby increasing the stability of the dispensing process. The rectangular groove 3 can also serve as a temporary storage channel for excess adhesive, preventing adhesive from accumulating between the temples and the groove walls of the clamping groove 2, reducing the risk of adhesion after curing. When the temples expand due to heat after dispensing, the groove structure of the rectangular groove 3 allows for local stretching of the silicone, reducing the probability of overall deformation of the clamp. The edges of the rectangular groove 3 can provide friction to prevent the temples from shifting due to vibration during dispensing, especially when used in humid environments. Metal clamps are prone to corrosion, and after absorbing moisture and corroding, dimensional fluctuations may occur, which can easily lead to temple jamming or dispensing deviation. Moreover, the production cost of metal clamps is relatively high, making it difficult to reduce production costs.

[0033] In this embodiment, as a preferred solution, the inner bottom wall of the rectangular groove 3 is a slope that gradually rises away from the clamping groove 2. When the dispensing pressure fluctuates, the overflowing glue is guided by the slope and flows away from the clamping groove 2, eventually converging at the end of the rectangular groove 3. This prevents the glue from seeping back into the contact surface between the temple and the groove wall. When the bottom of the temple contacts the slope, the slope generates a lateral force, pushing the temple to automatically slide towards the center of the clamping groove 2, effectively improving the placement accuracy. When the silicone mold is formed, the slope structure makes the demolding direction of the rectangular groove 3 consistent with the slope, avoiding the risk of tearing when demolding the right-angle groove. When the temple is heated and expands, the slope provides a gradual deformation space, avoiding stress concentration that could cause local tearing of the silicone, while cracks are more likely to appear at the bottom of the right-angle groove.

[0034] In this embodiment, as a preferred option, a clamp base 4 is also included. The clamp base 4 is detachably connected to the silicone clamp body 1 via a positioning component 5. The clamp base 4 and the silicone clamp body 1 are detachably connected via the positioning component 5 to form a composite structure of a rigid base and a flexible clamp. The silicone clamp body 1 undertakes the functions of flexible wrapping and deformation adaptation, avoiding direct contact between the rigid base and the temple, which would cause rigid damage. The clamp base 4 provides a base for connection with the dispensing equipment. The positioning component 5 can be installed and removed by means of pins, realizing quick assembly and disassembly of the silicone clamp body 1 and the clamp base 4. A single clamp base 4 can be adapted to multiple silicone clamp bodies 1, further reducing the cost of mold production and use.

[0035] In this embodiment, as a preferred solution, the positioning component 5 includes a positioning block 51 formed on the fixture base 4. The silicone clamp body 1 has a positioning hole 52 corresponding to the positioning block 51. The silicone clamp body 1 is slidably connected to the positioning block 51 through the positioning hole 52. The silicone clamp body 1 is pushed into the positioning block 51 along the length direction. It is inserted into the positioning hole 52 by the deformation of the silicone clamp body 1. No bolt fixing is required. The silicone clamp body 1 can improve the friction and maintain a certain connection stability. At the same time, the positioning block 51 can be quickly positioned when inserted into the positioning hole 52, reducing the process and time of position adjustment and reducing the number of steps.

[0036] In this embodiment, as a preferred solution, the positioning component 5 further includes a storage groove 53 formed on the surface of the clamp base 4. A first magnet 54 is fixedly connected to the inner bottom wall of the storage groove 53. A second magnet 55 is correspondingly provided on the surface of the silicone clamp body 1 facing the storage groove 53. The second magnet 55 is at least partially located in the storage groove 53 and abuts against the first magnet 54. The first magnet 54 is embedded in the bottom wall of the storage groove 53, and the second magnet 55 is preset at the bottom of the silicone clamp body 1. Both the first magnet 54 and the second magnet 55 are magnets, which are existing known technologies and are only cited here. When the silicone clamp body 1 is installed, the second magnet 55 moves with the silicone clamp body 1 to the top of the storage groove 53. As the silicone clamp body 1 falls, the second magnet 55 enters the corresponding storage groove 53. The second magnet 55 entering the storage groove 53 cooperates with the first magnet 54 to form an adsorption and locking.

[0037] In this embodiment, as a preferred option, an inflatable airbag 6 is also included. The inflatable airbag 6 is disposed within the positioning block 51. The positioning block 51 has a clearance opening 7 on its surface facing the clamping groove 2. The inflatable airbag 6 has a first state and a second state. In the first state, the inflatable airbag 6 is relatively contracted, located within the positioning block 51, and does not extend beyond the clearance opening 7. In the second state, the inflatable airbag 6 is relatively extended, with at least a portion extending beyond the clearance opening 7 and abutting against the inner wall of the positioning hole 52. This pushes the positioning hole 52, causing the clamping groove 2 to deform. Through the deformation of the clamping groove 2, the placed temple of the mirror is clamped. When the airbag is not inflated, it is completely concealed within the positioning block 51. With the clearance opening 7 open, the silicone clamp 1 can be freely disassembled and reassembled. At this time, the clamp slot 2 is in a naturally relaxed state, allowing the temple to be quickly inserted or removed. After inflation, the expansion airbag 6 expands, partially extending out of the clearance opening 7, squeezing the inner wall of the positioning hole 52, and pushing the side wall of the clamp slot 2 to deform in an oriented manner. After deformation, the clamp slot 2 actively tightens, applying a uniform covering force to the temple, eliminating gaps and suppressing vibration offset, and assisting the clamp slot 2 in further compensation to avoid insufficient clamping force on the temple. For temples of different widths, the slot width can be controlled by adjusting the air pressure of the expansion airbag 6, or a pressure relief valve can be set at the air inlet end of the expansion airbag 6. When the air pressure reaches the threshold, the pressure relief valve will start to release pressure.

[0038] The inflatable airbag 6 is a known technology that expands by introducing positive pressure gas.

[0039] In this embodiment, as a preferred option, the silicone clamp body 1 is provided with reinforcing blocks 8 inside both sides of the rectangular groove 3. The reinforcing blocks 8 are used to improve the toughness of the rectangular groove 3. By adding reinforcing blocks 8 inside both sides of the rectangular groove 3 of the silicone clamp body 1, the service life is improved by locally strengthening the rectangular groove 3. The reinforcing blocks 8 can be selected from nylon glass fiber or carbon fiber reinforced silicone.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
