Description

Technical Field

[0001] This invention belongs to the field of display module systems, and specifically relates to a cover plate display module that is easy to install with a robotic arm. Background Technology

[0002] As consumer electronics products (such as smartphones, tablets, and in-vehicle terminals) become increasingly diversified, the structure and performance of their display modules are gradually becoming key factors affecting the overall performance and market competitiveness of the devices. Especially against the backdrop of widespread adoption of intelligent manufacturing and automated assembly, how to achieve efficient and automated installation of core components such as glass covers in display modules, and how to ensure the overall structural strength, appearance stability, and optical performance of the modules, have become significant technical challenges in display module structural design.

[0003] In existing technologies, display modules generally include a supporting housing, display components (display layer and backlight layer) located inside, and a glass cover for protection and aesthetics. The glass cover is typically placed directly within the housing cavity and secured by adhesives, clips, or screws. However, during automated assembly, because the glass cover usually has smooth edges and lacks an effective contact gripping area, robotic arms often experience slippage, misalignment, or gripping failures due to insufficient friction when handling it, severely impacting production line efficiency and installation yield. Furthermore, the edges of the glass cover lack stable clamping or guiding structures within the module; if not securely fixed, it is prone to displacement, warping, or detachment during transportation or use, affecting product structural reliability and user experience.

[0004] On the other hand, most glass covers currently on the market are single-layer structures or simple coating structures, which have significant shortcomings in terms of durability, safety, and visual effect. For example, ordinary glass covers are easily scratched, worn, or chemically corroded during long-term use, reducing light transmittance and affecting display effects; when they break due to impact, there is a high risk of glass fragments flying, posing a significant safety hazard; and they lack decorative films or functional coatings, failing to meet users' higher demands for aesthetics and personalized appearance.

[0005] Especially in outdoor use scenarios or high-frequency contact operation conditions, the shortcomings of traditional cover plates in terms of UV resistance, surface hardness, stain resistance and color performance have restricted their application in high-end display devices.

[0006] In summary, existing display modules and their cover plate structures generally suffer from the following unresolved technical problems:

[0007] The lack of a structural design that facilitates stable gripping and insertion by robotic arms results in glass cover plates easily slipping off and being difficult to pick up and put down during automated assembly.

[0008] The glass cover has a simple fixing structure and lacks a multi-point pressing and guiding positioning structure, making it difficult to ensure the structural stability of the module during use and transportation.

[0009] The cover plate itself lacks sufficient functional structure, making it difficult to simultaneously meet the comprehensive requirements of durability, optical performance, safety, and aesthetic appearance.

[0010] Therefore, there is an urgent need for a display module structure that is suitable for automated assembly, has precise pressing and positioning functions, and has been comprehensively upgraded in terms of durability and optical performance, so as to effectively solve the above-mentioned technical bottlenecks in the existing technology and improve the overall performance and applicability of the display module in the production and terminal use process. Summary of the Invention

[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cover display module that is easy to install with a robotic arm.

[0012] To solve the above-mentioned technical problems, the technical method adopted by the present invention is as follows: The present invention discloses a cover display module that is easy to install with a robotic arm, including a housing cover and a housing main body base that matches and connects to the housing cover. The housing main body base is a hollow cavity with an opening. A glass cover body, a display layer, and a backlight layer are arranged sequentially from top to bottom in the hollow cavity. The four edges of the glass cover body are fitted to the inner wall of the hollow cavity, and the upper surface of the glass cover body is basically flush with or slightly lower than the upper end surface of the housing main body base.

[0013] An inclined groove for inserting a robotic arm is provided at the upper end face of the hollow cavity. The inclined groove forms an inclined surface, and the inclined surface forms an acute angle with the side of the glass cover body, so that the robotic arm can make full contact with the side after being inserted into the inclined groove, thereby increasing the friction and facilitating the gripping and placement of the glass cover body.

[0014] Furthermore, the outer end face of the main body base of the housing is provided with several slots, and the outer cover of the housing is provided with buckles that engage with the slots. Through the cooperation of the slots and buckles, the outer cover of the housing can be detachably installed on the main body base of the housing.

[0015] Furthermore, the inner edge of the outer casing cover extends downward in a vertical direction, and the extension is inserted into the hollow cavity and pressed against the upper surface of the glass cover body to prevent the glass cover body from shifting during use.

[0016] Furthermore, the glass cover body is made of high-strength, high-transmittance glass material, and the edges are chamfered to avoid scratches and chipping during assembly; the hollow cavity is a rectangular frame structure with guide bosses at the four corners to assist in positioning the glass cover body in the installation position.

[0017] Furthermore, there are two or more inclined slots, which are symmetrically arranged along the two opposite sides of the upper surface of the main body base of the housing to accommodate the insertion operation of the robot arm in different directions; the bottom of the hollow cavity is also provided with a buffer layer, located below the backlight layer, to buffer external impact and improve shock resistance.

[0018] Furthermore, the display layer is a liquid crystal display panel, an OLED display panel, or other flexible or rigid display units.

[0019] Furthermore, the lower surface of the inner edge of the outer casing cover is provided with an annular pressing edge, which is a flexible elastic buffer material layer used to buffer the compressive stress and improve the impact resistance.

[0020] Furthermore, the side of the glass cover plate body is provided with an anti-slip treatment structure, including but not limited to micro-protrusions or concave textures, to enhance the friction with the inclined surface of the groove and the inner edge.

[0021] Furthermore, the upper surface of the glass cover plate body is sequentially coated with a titanium oxide coating layer and at least one composite oxide layer, wherein the composite oxide layer includes one or more combinations of tantalum oxide, zirconium oxide and hafnium oxide;

[0022] The lower surface of the glass cover plate body has a photosensitive color-changing ink layer on the back edge area, and a polyurethane resin protective layer is provided below the photosensitive color-changing ink layer.

[0023] Furthermore, the titanium dioxide coating layer has a thickness of approximately 50–100 nm; the photosensitive color-changing ink layer has a thickness of 10–20 μm; the single-layer thickness of the composite oxide layer is 50–70 nm; and the polyurethane resin protective layer has a thickness of 50–100 μm. Beneficial effects

[0024] 1. This invention features multiple inclined slots on the upper surface of the base of the main body of the housing, each with an inclined surface forming an acute angle with the side of the glass cover plate. This allows the robot arm to make full contact with the side of the glass cover plate after insertion, creating a stable frictional gripping interface. This structural design differs from traditional methods that rely solely on adsorption or clamping of the glass surface, effectively avoiding gripping deviations and improving alignment accuracy. It is particularly suitable for efficient automated assembly of large-size or irregularly shaped glass, significantly increasing assembly speed and first-pass assembly success rate.

[0025] 2. To prevent the glass cover from shifting or detaching during assembly or use, this invention enhances its fixing effect through a multi-layered structural design. On one hand, the four edges of the glass cover body fit snugly against the inner wall of the hollow cavity, and are further aided by guide protrusions for positioning. On the other hand, the outer casing cover achieves a reliable detachable connection with the base via snap-fits, and its inner edge extends vertically downwards and presses against the upper surface of the glass cover body. Furthermore, the inner edge is provided with a flexible, elastic buffer edge, which can absorb assembly stress and resist external impacts when the cover is pressed. The overall structure ensures stable assembly and possesses excellent shock and drop resistance, making it suitable for demanding applications such as automotive, industrial, and outdoor use.

[0026] 3. To enhance the visual appeal and environmental adaptability of the glass cover, this invention sequentially deposits a titanium dioxide coating layer and at least one composite oxide layer (such as tantalum oxide, zirconium oxide, or hafnium oxide) on the upper surface of the glass cover body, forming a multifunctional optical layer with high light transmittance, anti-reflective properties, and anti-fingerprint characteristics. Simultaneously, a photosensitive color-changing ink layer and a polyurethane resin protective layer are provided on the lower surface of the glass cover body's frame area, allowing for different visual effects based on ambient light changes and preventing scratches and aging. This design balances visual aesthetics, optical performance, and structural protection, significantly outperforming existing, single-structure ordinary glass covers. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment provides a cover plate display module that is easy to install with a robotic arm, such as... Figure 1-4As shown, it includes: a casing cover 1 and a casing base 2. The casing base 2 is a hollow cavity 20 with an opening, and the hollow cavity 20 is provided with a glass cover body 3, a display layer 4 and a backlight layer 5 from top to bottom.

[0034] The edges of the glass cover body 3 are fitted to the inner wall of the hollow cavity 20 to ensure stable embedding of the cover. Its upper surface 31 is basically flush with or slightly lower than the upper end surface 21 of the base 2 of the housing body, thereby providing a tight contact surface for the subsequent pressing structure.

[0035] To achieve automated gripping and efficient assembly of the glass cover body 3, a slanted groove 22 for inserting a robotic arm is provided on the upper end face 21 of the main body base 2. The slanted groove 22 forms an inclined surface 221, which forms an acute angle with the side edge 311 of the glass cover body 3. This structure allows the robotic arm to fully contact the side edge 311 of the glass cover body 3 after insertion into the slanted groove 22, increasing friction and thus achieving more reliable and stable gripping and placement operations. Preferably, to accommodate different gripping directions of the robotic arm, two or more slanted grooves 22 can be provided and symmetrically distributed along opposite sides of the upper end face 21 of the main body base 2.

[0036] In terms of the connection structure, the outer end face of the main body base 2 of the housing is provided with several slots 23, and the outer cover 1 of the housing is provided with buckles 11 that engage with the slots 23. Through the cooperation of the slots 23 and the buckles 11, the outer cover 1 of the housing can be detachably installed on the main body base 2 of the housing, which is convenient for subsequent maintenance and replacement.

[0037] Preferably, to further prevent the glass cover body 3 from shifting or warping due to vibration or impact, the inner edge 10 of the outer casing cover 1 extends inward in the horizontal direction and presses against the upper surface 31 of the glass cover body 3. Furthermore, the lower surface of the inner edge 10 may be provided with an annular pressing edge made of a flexible elastic buffer material, which can effectively absorb stress fluctuations during the pressing process, improve the overall impact resistance, and extend the service life of the device.

[0038] The hollow cavity 20 has a rectangular frame structure with guide bosses 24 at its four corners for initial positioning and limiting during cover plate assembly, improving assembly accuracy and consistency. More preferably, the bottom of the hollow cavity 20 also has a buffer layer located below the backlight layer 5, which can buffer the module when it is subjected to external impacts, enhancing overall shock resistance.

[0039] Display layer 4 can be a liquid crystal display panel, an OLED display panel, or other flexible or rigid display units to meet the display needs of different application scenarios.

[0040] To enhance both appearance and functionality, the glass cover body 3 is made of high-strength, high-transmittance glass material, with chamfered edges to prevent damage caused by scratches or broken edges during assembly. Its sides 311 may feature anti-slip treatment structures, such as micro-protrusions or grooves, to further enhance friction with the inclined surface 221 and inner edge 10, improving the fixing effect.

[0041] In addition, such as Figure 5 As shown, to enhance optical performance, the upper surface 31 of the glass cover plate body 3 is sequentially coated with a titanium oxide coating layer 301 and at least one composite oxide layer, such as one or more combinations of tantalum oxide layer 302, zirconium oxide 303, and hafnium oxide 304, forming a functional surface with anti-reflection, anti-pollution, and enhanced visual clarity; a photosensitive color-changing ink layer 305 is provided in the back frame area of ​​its lower surface to achieve the display effect changing with the ambient light; a polyurethane resin protective layer 306 is further provided below the ink layer to effectively prevent scratches and aging.

[0042] The thickness of each of the above layers can be optimized according to the application scenario. For example, the thickness of the titanium oxide coating layer 301 is controlled at about 50–100 nm, the thickness of the photosensitive color-changing ink layer 305 is 10–20 μm, the thickness of the single layer of the composite oxide layer is 50–70 nm, and the thickness of the polyurethane resin protective layer 306 is 50–100 μm.

[0043] In summary, the display module provided in this embodiment, through reasonable mechanical structure design and the application of multifunctional materials, significantly improves automated assembly efficiency, structural fixation performance, and the product's optical and environmental adaptability, making it suitable for the production and application of various high-performance display devices such as smart terminals, automotive displays, and industrial touch screens.
