Description

Technical Field

[0001] The present application relates to the field of display screen packaging, and in particular to a packaging device for liquid crystal screens. Background Art

[0002] The working principle of LCD screen is based on the photoelectric effect of liquid crystal material. Specifically, it controls the arrangement of liquid crystal molecules by controlling the voltage to adjust the transmittance of light, thereby realizing the display of images. Due to the characteristics of low power consumption, low radiation, small size and low weight, LCD screen has become the mainstream display device in the electronic information equipment market. With the development of the market, technological progress and the improvement of people's living standards, the size structure of LCD screen is gradually developing towards the four super directions of ultra-large area, ultra-thin thickness, ultra-light weight and ultra-high integration. For example, LCD screens with a size of more than 85 inches are getting larger and thinner as the area of ​​the LCD screen increases. However, the elastic modulus and shear modulus of precision equipment such as LCD screens are usually relatively low. The vibration input during transportation will cause the stress and strain generated by such ultra-large area and ultra-thin thickness LCD screens to far exceed their allowable upper limit, and then the LCD screen will be damaged. The current market has noticed the problem of damage to ultra-large LCD screens during transportation.

[0003] Related technology can refer to the Chinese patent with announcement number CN220221907U, which discloses a liquid crystal display transportation protection structure, including a main body, wherein the front side of the main body is recessed with a protection groove, and the protection groove is adapted to the liquid crystal screen; the lower end of the main body is connected with a filling part, and the front direction of the filling part is provided with a convex filling boss, and the filling boss is adapted to the assembly gap between the liquid crystal screen and its chassis; the bottom end of the filling part is connected with a bearing part, and the front side of the bearing part is recessed with a U-shaped card groove, and the U-shaped card groove is adapted to the chassis of the liquid crystal screen.

[0004] With respect to the above-mentioned related technologies, the LCD display transportation protection structure avoids relative displacement, jitter and friction of the LCD screen in all directions during transportation by setting up a main body, a filling part and a bearing part, and can quickly pack a maximum number of LCD screen devices in the same packaging box, effectively improving the packaging efficiency and packaging quantity of the LCD screen, while reducing the transportation damage rate and transportation packaging cost, and improving the mass production efficiency of liquid crystal products. However, in the above-mentioned related technologies, the main body, the filling part and the bearing part are all designed separately for the LCD screen to be transported, and the versatility is extremely poor, resulting in high costs for producing such LCD display transportation protection structures. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a transportation device for transporting LCD screens with a size of more than 85 inches, which not only meets the mechanical requirements during transportation, but also solves the problems of complex packaging device structure, poor applicability of packaging device and high production cost.

[0006] (II) Technical solution In view of the deficiencies in the prior art, the present invention adopts the following technical solutions: a packaging device for a liquid crystal screen, comprising a device body, a cover plate, an aluminum bar, a buffer pad, a buffer gasket and a stopper, wherein the buffer pad, the buffer pad and the stopper are arranged in the device body, one side of the device body is a screen protection area, and the other side of the device body is a device forming and strengthening area, the screen protection area is used for the contact between the device body and the liquid crystal screen when the liquid crystal screen is transported, the screen protection area is used in conjunction with the cover plate, the device forming and strengthening area is used to ensure the rigidity and strength of the device body, the screen protection area has a supporting surface in contact with the liquid crystal screen, and the screen protection area is arranged on both sides of the device body in the length direction. There are buffer pad slots, block slots, accommodating slots, cover plate slots and desiccant slots. The cover plate is used in conjunction with the cover plate slot, the buffer pad is used in conjunction with the buffer pad slot, the block is used in conjunction with the block slot, and the buffer gasket is used in conjunction with the block. Buffer pad slots and accommodating slots are arranged on both sides of the width direction of the device body. The buffer pad, block and supporting surface cooperate to complete the clamping action of the LCD screen. The device forming and strengthening area is provided with reserved holes on both sides of the width direction of the device body, an aluminum bar is arranged inside the device body, reinforcing ribs are arranged in the length direction and width direction of the device forming and strengthening area, and a central reinforcement body is arranged in the width direction of the center position of the device forming and strengthening area.

[0007] By adopting the above technical scheme, the main body of the LCD screen is fixed in the screen mounting area through the cooperation between the device body and the cover plate, and the LCD screen is further positioned and fixed through the cooperation between the buffer pad and the cache pad slot, and the cooperation between the block and the block slot. The rigidity of the device body in the length direction is enhanced by arranging aluminum bars in the length direction of the device body, the overall structural strength of the device body is enhanced by arranging reinforcing ribs in the length direction and width of the device reinforcement area, and the rigidity of the device body in the width direction is enhanced by arranging a central reinforcement body in the width direction at the center position of the device forming reinforcement area.

[0008] Optionally, the support surface is required to have a flatness within 0.02, a reference plane within 0.5% of the verticality of the side surface of the device body, and the length and width of the support surface do not exceed the length and width of the liquid crystal screen it supports.

[0009] By adopting the above technical solution, the 85-inch LCD screen can be completely fitted with the supporting surface during transportation to ensure the clamping force generated during clamping. While satisfying the positioning and fixing of the LCD screen, it also ensures that the force, moment and torque exerted on the LCD screen will not exceed its own allowable limit, thereby avoiding force-induced deformation and structural damage of the LCD screen during transportation.

[0010] Optionally, the buffer block slots are respectively arranged on both sides of the width direction and one side of the length direction of the device body, and the block slot is arranged on the side of the length direction of the device body where there is no buffer block slot. The number of buffer block slots is adapted to the size of the clamped LCD screen, and the groove types of the buffer block slots and the block slots are both special-shaped grooves.

[0011] By adopting the above technical solution, the number of buffer block slots is adjusted to adapt to LCD screens of different size ranges, and the clamping force torque generated by clamping the LCD screen is controlled to be 0. The buffer block slot is set as a special-shaped groove for the purpose of fixing the buffer block, thereby playing the role of positioning and fixing the LCD screen. The buffer block located on one side of the length direction of the device body needs to cooperate with the two blocks on the other side to meet the mechanical performance requirements of LCD screen transportation.

[0012] Optionally, the cover plate slots are staggered on both sides of the length direction of the device body, the receiving grooves are arranged on both sides of the width direction and one side of the length direction of the device body, and the side where the receiving grooves are located in the length direction of the device body is the same side as the side where the block slots are located, and the desiccant slot is located on the side where no receiving grooves are arranged in the length direction of the device body, and the groove types of the cover plate slots and the receiving grooves are both rectangular grooves.

[0013] By adopting the above technical solution, the asymmetrical setting of the cover slot can save the space area of ​​the screen installation area. At the same time, the asymmetrical design of the cover slot can make it more time-saving and labor-saving for users to remove the cover. The receiving slot ensures the integrated transportation requirements that may be required for the LCD screen during transportation. The receiving slot can store items such as the LCD screen's wiring harness or control device. The rectangular receiving slot design can maximize the utilization of the storage space of the receiving slot.

[0014] Optionally, the reinforcing ribs are distributed in the forming and strengthening area of ​​the device, and the central reinforcement body is provided with a special reinforcing rib in the width direction of the device body, the rib width of the special reinforcing rib is 3 times that of the reinforcing rib, and the rib types of the reinforcing ribs and the special reinforcing ribs are both trapezoidal ribs.

[0015] By adopting the above technical solution, the designer can use less material while meeting the static performance requirements of LCD screen transportation, reducing the design difficulty while saving materials and reducing production costs. At the same time, the trapezoidal design of the reinforcing ribs and special reinforcing ribs minimizes production costs and facilitates demoulding.

[0016] Optionally, the reserved holes are molding process holes, the reference of the position size of the reserved holes is the same, the distance between two adjacent reserved holes on both sides of the width direction of the device body is the same, and the distance between two adjacent reserved holes on the same side in the length direction is the same.

[0017] By adopting the above technical scheme, the reserved holes are used to facilitate the demoulding of the clamp for clamping the aluminum bar when the reinforced aluminum bar is cast integrally with the device body. The purpose of the same distance between two adjacent reserved holes on both sides of the width direction of the device body is to ensure that the aluminum bar is evenly distributed in the device body. The purpose of the same distance between two adjacent reserved holes on the same side in the length direction of the device body is to ensure that the aluminum bar is aligned in the device body.

[0018] Optionally, the buffer block is made of polypropylene, and in the device body, the buffer block is connected to the buffer block slot via a special-shaped groove.

[0019] By adopting the above technical solution, different buffer blocks are required for transporting LCD screens of different sizes without changing the shape of the device main body. Therefore, the buffer blocks are reusable. The use of polypropylene material can make the buffer blocks more durable. The special-shaped groove connection can facilitate users to replace the buffer blocks. At the same time, the special-shaped groove can meet the assembly requirements of the buffer blocks and the buffer block slots in the device main body.

[0020] Optionally, the block is made of thermoplastic polymer material, and in the device body, the block is connected to the block slot via a special-shaped groove and adhesive, and the buffer gasket is made of polyurethane material, and the buffer gasket is adhesively connected to the block.

[0021] By adopting the above technical solution, the connection between the block and the block slot is strengthened by means of latches and adhesive connections to prevent shaking or loosening during transportation. At the same time, a buffer gasket is installed in the area where the block contacts the LCD screen to prevent wear between the LCD screen and the block during transportation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the device body of the present invention, the support surface of the LCD screen during transportation meets the requirements of force and displacement in the height direction of the device body, and the buffer pad and the stopper meet the requirements of force and displacement in the length and width directions. The cooperation of the buffer pad and the stopper in the device body makes the four corners of the LCD screen suspended, which can meet the requirements of preventing the four corners of the LCD screen from being bumped during transportation. At the same time, the cooperation between the buffer pad, the stopper and the buffer gasket meets the wear control of the LCD screen. 2. In the device body of the present invention, the rigidity and strength of the device itself are ensured by the device forming reinforcement zone. At the same time, multiple aluminum bars are cast together in the device body, further strengthening the ability of the device forming reinforcement zone to resist the axial torque of the length and width, avoiding the deformation of the device body due to external factors such as its own weight or the weight of the LCD screen, and ensuring the static deformation requirements of the LCD screen during transportation.

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0030] The present application embodiment discloses a packaging device for a liquid crystal screen. However, the embodiments of the present disclosure may be modified in a variety of different forms, and the scope of the present disclosure should not be interpreted as being limited by the embodiments described below. It is expected that the embodiments of the present disclosure will be interpreted as providing a more complete explanation of the present disclosure to those skilled in the art. Throughout the specification and the drawings, the same reference numerals indicate the same elements. In addition, various elements and regions are schematically drawn in the drawings. Therefore, the concept of the present disclosure is not limited by the relative sizes or spacings drawn in the drawings.

[0031] Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meanings as those generally understood by those of ordinary skill in the art to which the concept of the present disclosure belongs. It will be understood that common terms defined in dictionaries will be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and unless explicitly defined herein, these terms should not be interpreted in an overly formal sense.

[0032] Reference Figure 1 A packaging device for a liquid crystal screen comprises a device body 1, and also comprises a cover plate 6, a buffer pad 3, a buffer pad 4 and a stopper 2, wherein the buffer pad 3, the buffer pad 4 and the stopper 2 are arranged in the device body 1, the screen preservation area is used for the contact between the device body 1 and the liquid crystal screen 7, the screen preservation area is used in conjunction with the cover plate 6, the side of the device body 1 on which the liquid crystal screen 7 is loaded is the screen preservation area, the screen preservation area has a support surface 16 in contact with the liquid crystal screen 7, the screen preservation area has a buffer pad slot 13, a stopper slot 14, a container slot 16 on both sides of the device body 1 in the length direction The receiving groove 11, the cover plate slot 12 and the desiccant slot 15, the buffer pad slot 13 and the receiving groove 11 are provided on both sides of the width direction of the device body 1, the buffer pad slot 13 and the block slot 14 are connected with the buffer pad 3 and the block 2, and cooperate with the supporting surface 16 to form a clamping area for protecting and fixing the liquid crystal screen 7, and the side of the device body away from the supporting surface 16 is the device molding and strengthening area, and the device molding and strengthening area has reserved holes 17 on both sides of the width direction of the device body, has reinforcing ribs 18 in the length direction and the width direction, and has a central reinforcement body 19 in the width direction at the center position of the device body.

[0033] Reference Figure 1 The production process of the device body 1 adopts foam molding, and the material is mainly selected as expandable polystyrene (EPS). During molding, the user can independently select the shape of the screen installation area according to the size range of the mainstream LCD screen 7 in the market, so that the produced device body 1 can meet the loading size of the LCD screen 7 in an adjacent range, and improve the versatility of the same type of device body 1. The user can adjust the number and shape of the buffer pad slot 13 and the buffer pad 3, and adjust the shape of the block slot 14 and the block 2 to adapt to different LCD screens 7. In addition to meeting the flatness and verticality of the support surface 16, the user can also discretize the surface according to actual needs. The discretized support surface 16 can improve the material utilization rate to a certain extent. After the clamping is completed, the four corners of the LCD screen 7 and the four corners of the screen installation area do not contact each other to ensure that the LCD screen will not be damaged due to extrusion or collision. The reinforcing ribs 18 and the central reinforcing body 19 in the length direction and width direction are integrated with the device body 1.

[0034] Reference Figure 1The support surface 16 is required to have a flatness within 0.02, and the size reference is selected as the side of the device body 1, with a verticality within 0.5%. Any transportation vehicle will cause bumps. When clamping and fixing the LCD screen 7, the weak rigidity LCD screen 7 should be as close to the high rigidity support surface 16 as possible. Through this close contact, the acceleration of the LCD screen 7 is bound to the acceleration of the device body 1, which can greatly reduce the relative displacement of the LCD screen 7 caused by bumps during transportation, and avoid force-induced deformation and structural damage of the LCD screen 7 during transportation. The length and width of the support surface 16 do not exceed the length and width of the LCD screen 7 it supports, so as to ensure that the edge of the LCD screen 7 can be fully fitted with the buffer pad 3 and the stopper 2.

[0035] Reference Figure 1 The buffer block slots 13 exist on both sides of the width direction and one side of the length direction of the device body 1, and the block slots 14 exist on the side of the length direction of the device body 1 without the buffer block slots 13. The number of the buffer block slots 13 is determined according to the size of the clamped LCD screen 7. The "number of buffer block slots 13 is adapted to the size of the LCD screen 7" means that as the size of the LCD screen increases, the number of buffer block slots 13 increases. Figure 1 It is shown that when the size of the LCD screen 7 is 85 inches, the number of the buffer block slots 13 is more than 3, and there are only two block slots 14. The slot groove type of the buffer block slot 13 and the block slot 14 is a special-shaped groove, which refers to a groove with a degree of freedom of 1, including a circular groove, a diamond groove, an arrow groove, a trapezoidal groove, etc., preferably a trapezoidal groove.

[0036] Reference Figure 1 The buffer blocks 3 located on both sides of the width direction of the device body 1 are symmetrically positioned and equal in number. The buffer block 3 located on one side of the length direction of the device body 1 needs to cooperate with the two block blocks 2 on the other side to meet the mechanical performance requirements of the LCD screen 7 transportation. The cover plate slots 12 are located on both sides of the length direction of the device body 1, but the positions are asymmetrical and the numbers on both sides are not equal. The receiving grooves 11 are located on both sides of the width direction and one side of the length direction of the device body 1, and the side of the receiving grooves 11 in the length direction is the same side as the side of the block slots 14. The desiccant slot 15 is located on the side of the length direction of the device body 1 without the receiving grooves 11.

[0037] Reference Figure 1 and Figure 5The asymmetrical setting of the cover slot 12 can save the space area of ​​the screen installation area, thereby ensuring that the designer has enough space to set other characteristic structures such as the buffer pad slot 13 and the block slot 14. Since the cover 6 is too large, there is a situation where the curvature of different areas of the cover 6 is different when it is working, which leads to the problem that the cover 6 cannot be smoothly inserted into the cover slot 12. The asymmetrical design of the cover slot 12 can solve the above problem. The design purpose of the accommodating groove 11 is to ensure the integrated transportation requirements of the LCD screen 7 during transportation. The accommodating groove 11 can store items such as the wiring harness or control device of the LCD screen 7.

[0038] Reference Figure 2 The reinforcing ribs 18 are distributed in the device forming and strengthening area, and the reinforcing ribs 18 have the same rib type. The reinforcing ribs 18 in the length direction of the device body 1 and the reinforcing ribs 18 in the width direction of the device body 1 are perpendicular to each other. The central reinforcement body 19 has a special reinforcing rib 110 in the width direction of the device body 1, whose rib type width is 3 times that of other reinforcing ribs 18.

[0039] Reference Figure 2 The reinforcing rib 18 adopts a networking structure using a structural optimization method, so that the designer can use less material while meeting the static performance requirements of the LCD screen 7 during transportation. At the same time, the reinforcing rib 18 and the central reinforcement body 19 are integrally formed by foaming and casting with the device body 1 to achieve the purpose of saving materials and reducing production costs.

[0040] Reference Figure 3 The reserved holes 17 are formed process holes, and the position and size of the reserved holes 17 have the same reference. The distance between two adjacent reserved holes 17 on both sides of the width direction of the device body is the same, and the distance between two adjacent reserved holes 17 on the same side in the length direction is the same.

[0041] Reference Figure 3 and Figure 4 The reserved hole 17 is a process hole left by the fixture for removing the aluminum strip 5 when the aluminum strip 5 is integrally cast with the device body 1. The aluminum strips 5 are evenly arranged in the width direction of the device body 1, and the aluminum strips 5 are aligned with each other in the length direction to ensure the uniformity and symmetry of the rigidity and strength of the device body 1 in the length direction after casting.

[0042] Reference Figure 5 The buffer block 3 is made of polypropylene. In the device body 1, the buffer block 3 is connected to the buffer block slot 13 through a special-shaped groove. The buffer block 3 is made of polypropylene to ensure that the buffer block 3 does not lose its mechanical properties or change its chemical properties during repeated use. The buffer block 3 is connected to the buffer block slot 13 through a special-shaped groove to ensure that the buffer block 3 does not move in the working state.

[0043] Reference Figure 1 and Figure 5 The block 2 is made of thermoplastic polymer material, and is connected and glued to the block slot 14 in the device body 1 through a special-shaped groove, and the buffer pad 4 is made of polyurethane material and is glued to the block 2. The block 2 can position and fix the LCD screen 7 in the device body 1, and the glue can ensure that the block 2 does not loosen or shake during transportation, and the buffer pad 4 can effectively reduce the wear between the LCD screen 7 and the block 2.

[0044] The implementation principle of a packaging device for a liquid crystal screen in an embodiment of the present application is as follows: the support surface 16, the buffer pad 3, and the stopper 2 cooperate with each other to form a control chain to limit the degree of freedom of the liquid crystal screen 7 to 1, and then through the cover plate 6, the degree of freedom of the liquid crystal screen 7 is limited to 0.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
