Lens packaging scratch prevention cushioning pad device

Abstract

This utility model discloses a scratch-resistant cushioning pad device for lens packaging, specifically relating to the field of lens packaging technology. It includes a base for support, on which a cushioning support assembly is mounted. The cushioning support assembly includes a pressure plate positioned on top of the base. This utility model achieves comprehensive protection for the lens through multiple structural synergies. The placement groove of the inner liner precisely matches the lens, and the smooth inner wall treatment prevents friction scratches during placement. The sponge cushioning pads at the top of the pad and the bottom of the restraint cover not only absorb vibration and impact through elastic deformation but also form a soft contact interface, completely isolating the lens from direct contact with the hard structure and effectively preventing scratches caused by dust, particles, and other impurities.

Description

Technical Field

[0001] This utility model relates to the field of lens packaging technology, and more specifically, to a lens packaging anti-scratch cushioning pad device. Background Technology

[0002] As a core component in the field of optics, lenses are widely used in various products such as eyeglasses, cameras, microscopes, and medical devices. Their materials include a variety of transparent materials such as glass, resin, PC, and acrylic. Their core function is to achieve key roles such as vision correction, high-definition imaging, and ultraviolet protection by precisely controlling the refraction, reflection, or transmission path of light.

[0003] However, the optical performance of lenses is extremely sensitive to surface conditions: on the one hand, most lenses (especially those made of polymer materials such as resin and PC) have low surface hardness, typically only 2-4 on the Mohs scale, far lower than the dust, hard particles (such as sand and plastic scraps) and hard edges of the packaging materials themselves that may come into contact with the lens during packaging and transportation; on the other hand, the optical curvature, surface flatness, and smoothness of the lens are core performance indicators. Even micron-level scratches, indentations, or abrasions can disrupt the regularity of light propagation, leading to problems such as blurred images, distorted vision, glare, and reduced light transmittance. For example, tiny scratches on eyeglass lenses can directly affect the wearer's visual comfort and correction effect, damage to lenses in industrial testing instruments can cause deviations in testing data, and scratches on high-end camera lenses can significantly reduce image quality.

[0004] Traditional packaging often uses single foam pads, bubble wrap, or paper liners, providing only basic cushioning and failing to accurately position lenses. During transportation, lenses are prone to sliding and colliding within the packaging, rubbing against packaging materials or impurities and causing scratches. While some packaging includes placement slots, they lack a two-way elastic restraint structure, allowing impurities to accumulate in the gaps between the lens and the slot walls. Furthermore, when stacked, the pressure from the upper packaging is directly transmitted to the lens surface, causing indentations. Simultaneously, existing packaging lacks versatility; lenses of different sizes and curvatures require specialized packaging, increasing costs. The lack of a stable positioning structure during stacking also makes them prone to tipping and shifting, further exacerbating the risk of lens damage. These problems have long plagued lens production, transportation, and sales, leading to decreased product qualification rates, increased after-sales costs, and severely impacting industry development. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lens packaging anti-scratch cushioning pad device, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a lens packaging anti-scratch cushioning pad device, including a base for support, on which a cushioning support component is provided; The buffer support assembly includes a pressure plate disposed on the top of the base, a constraint cover for covering the outside of the lens is embedded in the middle of the pressure plate, and an abutment rod for pressing against the lens is disposed in the middle of the constraint cover. An inner lining plate is provided between the base and the pressure plate, and a placement groove for placing the lens is provided through the inner lining plate.

[0007] Optionally, in a possible implementation, the placement slot, the abutment rod, and the constraint cover are in the same axial direction, and the inner liner is bolted to the top of the base, the base is embedded with a top rod, the top of the top rod is provided with a pad, the pad is located directly below the placement slot, and the pad extends into the placement slot to support the lens; Optionally, in a possible implementation, connecting ears are provided on both sides of the pressure plate, and a stacked sleeve is provided in each connecting ear. The stacked sleeve is inserted and fixed to the connecting ear. A through hole is provided at the connection between the stacked sleeve and the connecting ear. The packages are stacked together and positioned by a limiting pin through the through hole. A buffer pad is provided at the top of the pad and the bottom of the constraint cover. The buffer pad is made of sponge. The constraint cover is threaded to the pressure plate. The downward extension length of the constraint cover and the abutment rod is adjusted by rotating the constraint cover, thereby adjusting the squeezing force of the constraint cover and the abutment rod on the lens. The technical effects and advantages of this utility model are as follows: Comprehensive protection for the lens is achieved through a multi-layered structure. The placement slot of the inner liner plate is precisely matched with the lens, and the smooth inner wall treatment avoids friction scratches during placement. The sponge cushioning pads at the top of the pad and the bottom of the restraint cover not only absorb the shock force through elastic deformation, but also form a soft contact interface, completely isolating the lens from direct contact with the rigid structure and effectively avoiding scratches caused by dust, particles and other impurities. The coaxial design of the restraint cover and the abutment rod ensures that the lens is subjected to uniform force, eliminating indentation damage caused by local pressure concentration, fundamentally ensuring the flatness and smoothness of the lens surface, and maintaining its original optical performance. By flexibly adjusting the downward pressure depth of the abutment rod through rotation, combined with the bottom support of the pad, a two-way fixing mode of upper pressure and lower support is formed, ensuring that the lens is completely positioned inside the packaging without any sliding space, thus completely solving the problem of damage caused by shaking and collision during transportation. The anti-slip texture on the bottom of the base further enhances the stability of placement. With the stacking positioning structure of the connecting ear and the stacking sleeve, multiple packages can be precisely fixed by the limiting pin. After stacking, the structure is stable, preventing tipping and displacement, and is suitable for various scenarios such as long-distance transportation and multi-layer warehousing.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Example 1 This embodiment discloses a scratch-resistant cushioning pad for lens packaging, which aims to solve the problems of scratches and wear that easily occur during the existing lens packaging process, and the lenses not being securely fixed after packaging, resulting in damage to optical performance due to shaking during transportation.

[0017] Specifically, such as Figure 1 , Figure 2 As shown, this device includes a base 1 for providing stable support. The base 1 is made entirely of rigid plastic, and its bottom is provided with anti-slip texture to effectively prevent slippage when packaging is stacked or placed. A complete cushioning support assembly is mounted on the base 1. This cushioning support assembly includes a pressure plate 2 horizontally disposed on the top of the base 1. The pressure plate 2 is also made of rigid plastic and is adapted to the external dimensions of the base 1 to ensure the overall structural harmony.

[0018] like Figure 4 , Figure 5 As shown, the pressure plate 2 has a threaded hole in its center, into which a constraint cover 3 is embedded for covering the outside of the lens. The constraint cover 3 is a hollow cylindrical structure with a smooth, burr-free inner wall. The constraint cover 3 is fixed to the pressure plate 2 by a threaded connection, and the downward extension length of the constraint cover 3 can be flexibly adjusted by rotating it. An abutment rod 4 is integrally formed in the center of the constraint cover 3 for pressing against the upper surface of the lens. The axis of the abutment rod 4 coincides with the axis of the constraint cover 3, and the bottom end of the abutment rod 4 has an arc-shaped transition structure to avoid local pressure concentration on the lens surface.

[0019] like Figure 2 , Figure 3 As shown, an inner liner 10 is detachably installed between the base 1 and the pressure plate 2. The inner liner 10 is made of lightweight foam material, which has a certain degree of cushioning elasticity. A placement groove 5 for placing lenses is opened through the inner liner 10. The inner diameter of the placement groove 5 matches the outer diameter of the lens to be packaged, and the inner wall of the placement groove 5 is smoothed to prevent scratches when placing the lens. The placement groove 5, the abutment rod 4, and the constraint cover 3 are all on the same axis to ensure that the lens can be accurately positioned and constrained after placement. At the same time, the inner liner 10 is installed on the top of the base 1 by four symmetrically distributed bolts. The bolt connection method facilitates the disassembly and replacement of the inner liner 10. The inner liner 10 of the corresponding placement groove 5 specification can be replaced according to different lens sizes, improving the versatility of the device.

[0020] like Figure 2 As shown, a top rod 6 is embedded vertically inside the base 1. The top rod 6 is made of stainless steel and has good rigidity and wear resistance. A pad 7 is fixedly installed on the top of the top rod 6. The pad 7 has a circular structure and its diameter is slightly smaller than the inner diameter of the placement groove 5. The pad 7 is located directly below the placement groove 5. The top of the pad 7 extends into the placement groove 5 to support the lens placed in the placement groove 5 from the bottom, forming a two-way support structure.

[0021] Example 2 Based on Example 1, this example discloses a scratch-resistant cushioning pad device for lens packaging, such as... Figure 4 , Figure 5 As shown, the left and right sides of the pressure plate 2 are integrally formed with connecting ears 8. The two connecting ears 8 are symmetrically arranged, and each connecting ear 8 is inserted and fixed with a stacked sleeve 9. The stacked sleeve 9 is a hollow cylindrical sleeve, and its outer diameter is adapted to the inner diameter of the insertion hole opened on the connecting ear 8. The connection between the stacked sleeve 9 and the connecting ear 8 is provided with a coaxial through hole. When multiple of these devices are stacked and packaged, the limiting pin can be passed through the corresponding through hole of each device to achieve precise positioning and fixation of multiple packages, and avoid displacement or tipping during the stacking process.

[0022] like Figure 2As shown, the top of the pad 7 and the bottom of the constraint cover 3 are both fixed with cushioning pads by adhesive bonding. The cushioning pads are made of high-density sponge, which has good elasticity and cushioning performance. The surface of the cushioning pads is finely treated so that it will not scratch when in contact with the lens surface, and can effectively absorb the vibration and impact force generated during transportation.

[0023] The specific working principle of this embodiment is as follows: First, according to the size of the lens to be packaged, select the inner liner plate 10 with the corresponding size of the placement slot 5, and fix the inner liner plate 10 on the top of the base 1 with bolts to ensure that the inner liner plate 10 is installed flat and without looseness. Place the lens to be packaged stably in the placement slot 5. The lower surface of the lens is in close contact with the cushioning pad on the top of the pad 7. The pad 7 provides stable support for the lens. Cover the pressure plate 2 so that it covers the inner liner plate 10. At this time, the constraint cover 3 is located directly above the lens. Rotate the constraint cover 3 so that it extends downward until the buffer pad at the bottom of the contact rod 4 gently contacts the upper surface of the lens and forms a moderate pressure. By adjusting the extension length of the constraint cover 3, the squeezing force of the contact rod 4 on the lens can be precisely controlled, which ensures that the lens is firmly fixed and avoids excessive pressure that may cause the lens to deform or produce indentations. When multiple packaged devices need to be stacked, align the bottom of the base 1 of the upper device with the top of the pressure plate 2 of the lower device, so that the bottom of the base 1 of the upper device corresponds to the connecting ear 8 and the stacking sleeve 9 of the lower device. Then, pass the limiting pin through the through hole on the connecting ear 8 and the stacking sleeve 9 of the upper and lower devices to achieve stacking and positioning of multiple devices. After stacking, the overall structure is stable and there will be no relative sliding.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
