Description

Technical Field

[0001] This invention relates to the field of optical lens assembly technology, and in particular to a lens nut fastening adhesive dispensing device and method. Background Technology

[0002] The fastening and adhesive application of nuts and lenses are core processes to ensure the structural stability, sealing performance, and functional reliability of products.

[0003] Traditional production relies on manual labor or semi-automated equipment. While these methods can complete basic operations, they have significant shortcomings in terms of fastening accuracy, dispensing uniformity, and consistency control. This makes it difficult to meet the stringent quality stability requirements of high-precision optical products, and can easily lead to product performance fluctuations or damage risks. Manual dispensing is prone to uneven adhesive application, adhesive path deviation, or damage to the product surface due to variations in technique. Fastening force control relies on experience, which can easily result in insufficient or excessive force, affecting sealing performance. In mass production, operational differences lead to inconsistencies in fastening degree and dispensing thickness, affecting product stability. Therefore, there is a need for an automated, stable, and uniform lens nut fastening and dispensing device and method. Summary of the Invention

[0019] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] Specific embodiments, combined with Figures 1 to 11 The technical solution of the present invention will be further illustrated as shown.

[0021] A lens nut fastening and dispensing device includes a base body 4. One side of the base body 4 is provided with a fastening mechanism 1 for feeding nuts and a clamping mechanism 2 for feeding products to be fastened and dispensed. The fastening mechanism 1 includes a feeding component 11 for fixing / loosening the nut and a first moving component 12 for driving the nut closer to the product to be fastened and dispensing to complete the fastening. The feeding component 11 is provided with a buffer mechanism to prevent damage to the product to be fastened and dispensing when the first moving component 12 drives the nut downwards to the fastening position. The clamping mechanism 2 includes a clamping assembly 21 for clamping and fixing the product to be fastened and dispensing, and a rotating assembly 22 located on one side of the clamping assembly 21 for driving the clamping assembly 21 to rotate. The other side of the base body 4 is provided with a dispensing mechanism 3 that, after the nut and the product to be fastened and dispensing are fastened, works with the clamping mechanism 2 to evenly dispense adhesive onto the fastened product. The base body 4 is provided with a control panel 40 for controlling the actions of the fastening mechanism 1, the clamping mechanism 2, and the dispensing mechanism 3.

[0022] For example, when lenses are fastened to nuts as products requiring adhesive dispensing, it is essential to ensure the product's structural stability, sealing performance, and functional reliability. Traditional production relies on manual labor or semi-automated equipment, which, while capable of basic operations, suffers from significant deficiencies in fastening accuracy, dispensing uniformity, and consistency control. This makes it difficult to meet the stringent quality stability requirements of high-precision optical products, potentially leading to performance fluctuations or damage. Manual dispensing is prone to uneven adhesive application, adhesive path deviation, or surface damage due to variations in technique; fastening force control relies on experience, easily resulting in insufficient or excessive force, affecting sealing performance; and in mass production, operational differences lead to inconsistent fastening degrees and dispensing thicknesses, impacting product stability.

[0023] In this implementation case, precise coordination between the locking and dispensing processes is achieved through the collaborative work of various mechanisms. The clamping mechanism, through the linkage of the clamping and rotating components, ensures reliable product clamping and uniform rotation, guaranteeing stable and controllable locking. The dispensing mechanism operates synchronously after locking, cooperating with the rotating components to achieve uniform glue distribution. In addition, the control panel coordinates the timing of the actions of each mechanism to eliminate differences in manual operation, improve locking accuracy and dispensing consistency, and effectively ensure the stability and reliability of mass production of high-precision optical products.

[0024] Meanwhile, through a modular design, the control panel is electrically connected to the locking mechanism, clamping mechanism, and dispensing mechanism. The control panel is equipped with at least a reset button, a stop button, a start button, and an emergency stop switch to facilitate the adjustment of the operating parameters of the locking, clamping, and dispensing mechanisms. In other words, the control panel controls the operation of these mechanisms, each with independent functions and high adjustability. For example, the feeding component of the locking mechanism and the clamping assembly of the clamping mechanism can be quickly replaced to adapt to different specifications of nuts and products, and the rotating components can be parametrically controlled to adapt to diverse rotational requirements. Furthermore, the dispensing mechanism can be programmed and adjusted via the control panel to adjust the dispensing method, dispensing thickness, etc., to adapt to different dispensing requirements.

[0025] In this embodiment, the clamping mechanism 2 includes a clamping base 20 disposed on the machine base body 4, the rotating component 22 includes a rotating drive 221 disposed on one side of the clamping base 20 and a rotating component 222 disposed on the other side of the clamping base 20 and driven by the rotating drive 221, the clamping component 21 is rotatably disposed on the rotating component 222, and the dispensing mechanism 3 includes a dispensing base 30 disposed on the machine base body 4, a slidable dispensing component 31 disposed on the dispensing base 30, and a second sliding component 32 disposed on the dispensing base 30 for controlling the sliding of the dispensing component 31.

[0026] One of the rotating drive components can be connected to an external control system, enabling the rotating component to rotate at a uniform speed and the locking to be controllable. This achieves automated locking through mechanical linkage, improving production efficiency while ensuring consistent locking quality. The clamping mechanism uses a rotating drive component and a rotating component to ensure stable rotation of the clamping assembly, improving the uniformity of force on the product and the locking accuracy during locking. The dispensing mechanism controls the dispensing assembly to move to the working area through a second positioning component, cooperating with the clamping mechanism to drive the clamping assembly to rotate, ensuring uniform distribution of adhesive during dispensing and avoiding uneven adhesive amount or adhesive path deviation.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the dispensing base 30 is provided with a second slide rail 300, the second sliding member 32 includes a second slider 321 for cooperating to drive the dispensing assembly 31 to slide and a second cylinder 322 for driving the second slider 321 to slide, the dispensing assembly 31 includes a dispensing body 311 disposed on the second slider 321 and a dispensing element 312 disposed on the dispensing body 311, and the dispensing assembly 31 is provided with an adjustment component 5 for adjusting the position of the dispensing element 312.

[0028] The second slide rail works in conjunction with the second slider to achieve smooth sliding of the dispensing component, and the second cylinder drive ensures accurate sliding trajectory and effectively avoids glue path deviation; the adjustment component can finely adjust the position of the dispensing part to adapt to the dispensing needs of different products and improve the versatility of the equipment.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the adjustment component 5 includes a plurality of first manual fine-tuning slides 51 disposed between the second slider 321 and the dispensing body 311 for adjusting the horizontal position of the dispensing body 311, and a second manual fine-tuning slide 52 disposed on the upper side of the dispensing body 311 for adjusting the vertical position of the dispensing component 312.

[0030] The position of the dispensing component is adjusted by using the first and second manual fine-tuning slides. During batch dispensing, this ensures that the dispensing inlet can reach the dispensing area, thereby guaranteeing the accuracy and stability of the dispensing position.

[0031] In the above-described configuration of the first manual fine-tuning slide 51 and the second manual fine-tuning slide 52, preferably, the first manual fine-tuning slide 51 includes a first fine-tuning knob 511 for adjusting the movement of the dispensing body 311 in the x-axis or y-axis direction and a first locking knob 512 for unlocking / restricting the adjustment of the first fine-tuning knob 511, and the second manual fine-tuning slide 52 includes a second fine-tuning knob 521 for adjusting the movement of the dispensing part 312 in the z-axis direction and a second locking knob 522 for unlocking / restricting the adjustment of the second fine-tuning knob 521.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the dispensing component 312 includes a dispensing syringe 3121 and a dispensing needle 3122 that are inclined relative to the horizontal plane. The dispensing needle 3122 includes an inclined needle 31221 that is inclined relative to the horizontal plane and a horizontal needle 31222 that is parallel to the horizontal plane and communicates with the flow channel of the inclined needle 31221. The minimum angle between the inclined needle 31221 and the horizontal plane is α, where 30°≤α≤60°.

[0033] By setting the horizontal angle of the inclined needle section, sufficient working space is left between the clamping mechanism and the dispensing mechanism. At the same time, the inclined dispensing needle and dispensing syringe ensure uniform dispensing and avoid uneven dispensing or damage to the product surface.

[0034] Optionally, as a preferred embodiment of this solution and not a limitation, the minimum angle α between the tilted needle 31221 and the horizontal plane is 45°.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the clamping assembly 21 includes a plurality of grippers 211 that cooperate to clamp the product to be locked with adhesive. Each gripper 211 includes a bearing portion 2111 for carrying the product to be locked with adhesive and a clamping portion 2112 for cooperating to clamp the product to be locked with adhesive. The clamping portion 2112 is provided with a locking portion 2113 for cooperating to install and clamp the product to be locked with adhesive.

[0036] The multi-claw design enables stable clamping and precise positioning of the product to be bonded. The load-bearing part provides basic support to ensure product stability. The gripping and locking parts work together to clamp the product, improving clamping reliability and preventing product displacement or detachment during the bonding process. This design replaces manual bonding operations. The operator only needs to feed the nut and the product to be bonded separately. Subsequent bonding can be completed by the clamping and locking mechanisms, improving bonding efficiency. At the same time, the multi-point uniform force design reduces the risk of product surface damage and ensures consistent bonding quality.

[0037] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the locking part 2113 is a polyurethane strip with excellent elasticity and wear resistance.

[0038] By using urethane strips as the locking part, their excellent elasticity enables flexible contact during the locking process, effectively absorbing the locking impact and reducing the risk of product surface damage. At the same time, their wear-resistant properties extend the service life of components, reduce maintenance frequency, and improve equipment operation stability.

[0039] In this embodiment, the locking mechanism 1 includes a locking support 10, on which a first slide rail 100 is provided. The first moving member 12 includes a first cylinder 121 disposed on the locking support 10 and a sliding member 122 driven by the first cylinder 121 to slide along the first slide rail 100. One side of the sliding member 122 is slidably engaged with the first slide rail 100, and the other side of the sliding member 122 is engaged with the feeding member 11.

[0040] The first cylinder drives the sliding component to slide along the first slide rail, achieving precise linear driving and positioning for nut fastening. The fastening support and the first slide rail work together to provide stable guidance, ensuring that the movement trajectory of the sliding component is precise and controllable, and avoiding deviation or shaking during the fastening process.

[0041] In addition, by cooperating with the sliding component and the feeding component, the nut can complete the feeding and conveying action, and transfer the nut to the clamping mechanism. With the cooperation of the rotating component, the feeding and locking actions of the nut can be seamlessly connected, thereby improving the degree of automation.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking support 10 includes a locking body 101 and a locking leg 102. The slide rail 100 and the first moving member 12 are both disposed on the locking body 101. A third manual fine-tuning slide 103 for adjusting the position of the locking body 101 is provided between the locking body 101 and the locking leg 102. The manual fine-tuning slide provides flexible displacement control. When it is necessary to lock different specifications of dispensing products and nuts, the relative position between the suction pen and the clamping component can be adjusted by manually adjusting the slide. After the suction pen and the clamping component are aligned, the subsequent feeding of nuts, feeding, and rotational locking between the dispensing product and the nut can all be completed by the locking mechanism and the clamping mechanism, thereby improving the versatility of the equipment.

[0043] In the aforementioned configuration of the third manual fine-tuning slide 103, preferably, the third manual fine-tuning slide 103 includes a third fine-tuning knob 1031 for adjusting the movement of the locking body 101 in the x-axis direction, a fourth fine-tuning knob 1032 for adjusting the movement of the locking body 101 in the y-axis direction, a third locking knob 1033 for unlocking / restricting the adjustment of the third fine-tuning knob 1031, and a fourth locking knob 1034 for unlocking / restricting the adjustment of the fourth fine-tuning knob 1032.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the feeding component 11 includes a suction pen 111 that is applied to the feeding nut in conjunction with the nut, and a vacuum connector 112 for connecting to a vacuum pumping device so that the suction pen 111 vacuum-adsorbs the nut. The suction pen 111 has a plurality of vacuum suction holes 1110 that communicate with the vacuum connector 112 evenly distributed on the side facing the clamping mechanism 2.

[0045] Specifically, a vacuum device is connected to one side of the vacuum connector. When the nut is placed on the suction pen, the vacuum suction creates a vacuum between the nut and the pen to firmly adhere the nut, achieving stable adhesion and precise feeding. Multiple evenly distributed vacuum suction holes enhance adhesion uniformity, preventing the nut from falling off or shifting during the fastening process and improving fastening accuracy. Vacuum adhesion replaces mechanical clamping, reducing the risk of physical damage to the nut surface and ensuring product appearance quality. This structure integrates with an automation system to achieve fully automated control of the nut feeding, positioning, and fastening process, reducing the need for manual intervention and improving production efficiency and consistency of fastening quality. Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the sliding member 122 includes an L-shaped pen holder 1221 for cooperating with the feeding member 11, and a slider 1222 with a groove that is fixedly connected to the pen holder 1221 on one side and slidably cooperates with the slide rail 100 on the other side, wherein the pen holder 1221 is slidably cooperated with the pen 111.

[0046] Among them, the L-shaped pen holder can optimize the spatial layout and improve the compactness of the equipment. It can be used with the clamping mechanism to achieve aligned installation. The sliding cooperation between the slider and the slide rail can ensure precise and controllable movement trajectory and reduce the risk of locking deviation. The sliding cooperation design between the pen holder and the pen allows the pen position to be flexibly adjusted to adapt to the locking requirements of different sized nuts and enhance the versatility of the equipment.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the pen holder 1221 includes a first mounting plate 12211 that cooperates with the slider 1222 and a second mounting plate 12212 that cooperates with the pen 111. The pen 111 includes a mating part 1111 for cooperating with the pen holder 1221 and an adsorption part 1112 for adsorbing a nut. The length of the mating part 1111 is a, and the width of the second mounting plate 12212 is b, where a>b.

[0048] The length of the mating part is greater than the width of the second mounting plate, allowing for vertical adjustment of the suction pen. This prevents the nut from directly damaging the product being glued when it is being fed to the surface, reducing the risk of product damage. Furthermore, the sliding fit design allows for fine-tuning of the suction pen's position to accommodate different nut sizes, enhancing the equipment's versatility.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the buffer mechanism includes a buffer baffle 113 disposed on the side near the adsorption part 1112, a baffle 114 disposed on the side away from the adsorption part 1112, and a buffer spring 115 disposed between the second mounting plate 12212 and the buffer baffle 113 for providing buffering. The second mounting plate 12212 is disposed between the buffer baffle 113 and the baffle 114. The shaft diameter m of the mating part 1111 is smaller than the shaft diameter n of the baffle 114 and the shaft diameter p of the buffer baffle 113. The thickness of the buffer baffle 113 is c, where b + c < a.

[0050] The buffer baffle absorbs the impact force during locking, reducing the risk of product damage; the dimensional fit between the baffle and the second mounting plate ensures installation stability and prevents the pen from falling off or shifting. The dimensional relationship between the buffer baffle, the mating part, and the second mounting plate optimizes the spatial layout, prevents component interference, and improves equipment reliability.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, a buffer spring 115 is provided between the second mounting plate 12212 and the buffer baffle 113 to provide buffering when the suction pen 111 is driven to move the nut to the clamping mechanism 2 to hold the adhesive product to be locked.

[0052] A buffer spring installed between the second mounting plate and the buffer baffle enables flexible buffer control during the fastening process. Specifically, the buffer spring absorbs impact energy when the nut contacts the product to be fastened, reducing the risk of mechanical impact damage to the product. At the same time, it avoids fastening position displacement caused by rigid contact, improving fastening accuracy. While ensuring efficient fastening, the buffer design reduces surface damage to the product and improves the consistency of fastening quality.

[0053] More preferably, an oil-free bushing 116 is provided between the pen holder 1221 and the pen 111 to reduce friction and wear.

[0054] The present invention proposes a lens nut fastening and dispensing device, which achieves precise coordination between fastening and dispensing processes through the coordinated work of various mechanisms. The clamping mechanism 2 is linked with the clamping component 21 and the rotating component 22 to ensure stable and controllable fastening. The dispensing mechanism 3 operates synchronously after fastening is completed, and works with the rotating component 22 to achieve uniform distribution of adhesive, thereby improving the consistency of product quality.

[0055] Specifically, the horizontal position of the dispensing component 312 is adjusted by the first manual fine-tuning slide 51, and the vertical position of the dispensing component 312 is adjusted by the second manual fine-tuning slide 52 to ensure that the dispensing component 312 can move and stabilize in the working area. The position of the locking body 101 is adjusted by the third manual fine-tuning slide 103 to ensure that the suction pen 111 of the feeding component 11 corresponds to the position of the clamping component 21, that is, to ensure that the nut and the lens are aligned, so as to facilitate the downward movement of the nut and the alignment and locking of the lens. After the position of the locking body 101 is adjusted, the cylinder 121 drives the sliding component 122 to slide along the first slide rail 100. The suction pen 111 connected to one side of the sliding component 122 also moves toward the clamping component 21 until it contacts the lens on the clamping component 21. The rotation drive component 221 of the clamping mechanism 2 drives the rotating component 222 to rotate. Since the clamping component 21 is located on the rotating component 222 and rotates with the rotating component 222, the lens is also driven to rotate to complete the locking with the nut.

[0056] In this process, the slider 1222 engages with the first slide rail 100, one side of the pen holder 1221 is connected to the slider 1222, and the other side is movably engaged with the pen holder 111. The length of the engaging part 1111 of the pen holder 111 is greater than the thickness of the second mounting plate 12212 of the pen holder 1221, allowing the pen holder 111 and the pen holder 1221 to have a certain amount of clearance for sliding. Combined with the limiting structures on both sides, this prevents the nut from damaging the lens when driving the lens of the nut. Furthermore, a buffer spring 115 is provided between the second mounting plate 12212 and the pen holder 111 to provide buffering during the contact process between the nut and the lens, ensuring stable contact and protecting the product. In addition, the clamping assembly 21 consists of multiple grippers 211 to cooperate in clamping the lens. Each gripper 211 has a clamping part 2112 on which it is fitted and clamps the product to be glued. The clamping part 2113 is made of urethane strip with excellent elasticity and wear resistance. The excellent elasticity of the urethane strip achieves flexible contact during the clamping process, effectively absorbs the clamping impact, reduces the risk of product surface damage, extends the service life of the component, reduces the frequency of maintenance, and improves the stability of equipment operation.

[0057] Once the fastening is complete, the suction pen 111 releases the vacuum, thus releasing the nut. The loading component 11, driven by the first cylinder 121, leaves the fastening area. The second cylinder 322 drives the second slider 321 to move, causing the dispensing component 312 to move along the second slide rail 300 to the working area. The dispensing assembly 31 then dispenses glue, which, combined with the rotating component 222's uniform rotation of the clamping assembly 21, achieves uniform dispensing and uniform glue application. The entire process can be controlled by the control panel 40 to ensure the stability of fastening and dispensing, product safety, and the accuracy and consistency of finished products during mass production.

[0058] A lens nut fastening adhesive dispensing method, used to complete the fastening adhesive dispensing using the lens nut fastening adhesive dispensing device described above, includes the following steps: S1: Installation and debugging. Install and adjust the positions of the locking mechanism 1, clamping mechanism 2 and dispensing mechanism 3 to ensure that the loading part 11 corresponds to the position of the clamping component 21. Through the control panel 40, adjust the positions of the buffer mechanism and dispensing mechanism 3 according to the size of the product to be locked and dispensed, such as a lens, to ensure that the nut is securely locked to the product to be locked and that the dispensing mechanism 3 can cooperate with the clamping mechanism 2 to dispense glue evenly after the nut and lens are locked. S2: Loading, the loading nut is fixed to the locking mechanism 1, and the loading product to be locked and glued is fixed to the clamping mechanism 2; S3: Locking. The locking mechanism 1 is controlled by the control panel 40 to move the nut to the product to be locked. When the nut is in place, the clamping assembly 21 is driven by the rotating assembly 22 to perform the locking operation. S4: After dispensing and locking, the locking mechanism 1 is controlled by the control panel 40 to loosen the nut and move out of the working space. Then, the dispensing mechanism 3 is driven to move to the product to be dispensed after locking. The rotating component 22 drives the clamping component 21 to rotate at a uniform speed to achieve uniform dispensing of the product. S5: Material picking. After dispensing is completed, reset the dispensing mechanism 3 through the control panel 40, remove the product after the locking and dispensing is completed, and repeat steps S2-S5 to perform the locking and dispensing work in batches.

[0059] Specifically, in step S1, the position of the locking body 101 is adjusted by the third manual fine-tuning slide 103 so that the nut fixed by the locking body 101 can be aligned with the lens fixed by the clamping assembly 21, and serve as a reference for subsequent locking. The position of the dispensing assembly 31 is adjusted by the first manual fine-tuning slide 51 and the second manual fine-tuning slide 52 to handle dispensing of lenses of different sizes, so that the dispensing component 312 can accurately reach the working position after being driven, and cooperate with the rotating assembly 22 to drive the clamping assembly 21 to rotate at a uniform speed to achieve uniform dispensing.

[0060] In addition, the control parameters for locking and dispensing are preset in advance via the control panel 40. Specifically, depending on the lens size, the stroke of the first positioning component 12 driving the loading component 11 is adjusted via the control panel 40. This, combined with a buffer mechanism, prevents damage to the lens from the downward movement of the nut, ensuring the stability and reliability of the high-precision optical products. The stroke of the second positioning component 32 driving the dispensing assembly 31 is adjusted via the control panel 40, ensuring that the dispensing assembly 31 accurately reaches the dispensing position during dispensing, guaranteeing dispensing accuracy. Simultaneously, the rotation parameters of the rotating component 22 are controlled via the control panel 40 to ensure the stability and reliability of mass production of high-precision optical products.

[0061] Furthermore, step S2 also includes the following steps: S21: Loading nut, place the nut at the suction pen 111, start the vacuum device, and through the vacuum connector 112 connected to the vacuum device and the vacuum suction hole 1110 with the same vacuum connector 112, vacuum is drawn between the suction pen 111 and the nut to achieve vacuum adsorption of the nut on the suction pen 111. S22: Loading lens, by placing the lens on the clamping assembly 21 formed by multiple grippers 211, the locking part 2113 uses urethane strips to provide stable constraint while avoiding damage to the lens; Furthermore, during step S3, the locking mechanism 1 is controlled by the control panel 40, that is, the first positioning component 12 is controlled to drive the loading component 11 to carry the nut downward. In this process, the stroke of the first positioning component 12 is planned in step S1 to ensure stability during batch processing. At the same time, during the contact between the nut and the lens, the suction pen 111 and the suction pen holder 1221 slide together, and the buffer mechanism set between them ensures stable contact, which facilitates subsequent locking and prevents excessive contact that could damage the nut and the lens.

[0062] Once the nut and lens are in contact, the clamping mechanism 2 is controlled via the control panel 40, which in turn controls the rotating component 22 to drive the clamping component 21 to rotate, thereby driving the lens to rotate and locking the nut and lens together. During this process, the rotation parameters of the rotating component 22 are planned in step S1; the rotation direction, rotation speed, and rotation time are all limited to ensure the stability and reliability of mass production of high-precision optical products.

[0063] Furthermore, in step S4, the nut is first vacuum-adsorbed onto the suction pen 111 by the control panel 40. Then, the loading component 11 is moved away from the nut and lens area by the first positioning component 12, leaving working space for the dispensing mechanism 3 to enter. The dispensing mechanism 3 is then driven by the control panel 40, that is, the dispensing component 31 is driven to move by the second positioning component 32 until the dispensing component 31 enters the dispensing area. Then, the dispensing component 312 is driven to dispense glue by the control panel 40. At the same time, the rotating component 22 drives the clamping component 21 to rotate, so that the dispensing mechanism 3 and the clamping mechanism 2 cooperate to complete the uniform dispensing work.
