[0032] EMBODIMENT

[0033] As shown in Figure 1 , a conveying pallet comprises a fixing assembly 1 and a supporting assembly 2 arranged on the fixing assembly 1, and the supporting assembly 2 is used for placing a liquid crystal panel.

[0034] As shown in Figure 1 , the fixing assembly 1 comprises two fixing frames 11 and a bottom frame 12, the top of the two fixing frames 11 is fixedly connected to form two inclined surfaces, the angle between the two inclined surfaces is 30°-60°, and the supporting assembly 2 is arranged on the inclined surfaces.

[0035] The smaller included angle may be more suitable for applications where the liquid crystal panel needs to be set with a gentler inclination, such as reducing the unevenness of light reflection or providing a larger working surface; the design of the inclined surface can help adjust the position of the support assembly relative to the light source or other reference points to achieve better light distribution, visual effects, or operational convenience; the design of the inclined surface and the included angle is crucial for improving the uniformity of the light source passing through the support assembly to the liquid crystal panel, and a proper included angle can help better control the propagation path of the light, reduce shadow areas and bright spots, and thus achieve more consistent brightness performance.

[0036] As the two fixed frames 11 expand to both sides, the angle of the included angle between the two inclined surfaces also increases, thereby improving the uniformity of the light source passing through the support assembly 2 to the liquid crystal panel 3. Specifically, a larger included angle can cause the light to scatter at a wider angle, helping to reduce hot spots (i.e., overly bright areas) and dark areas, thereby improving the brightness uniformity of the entire display surface; by adjusting the angle of the inclined surface, the design of the light path can be optimized so that the light is more uniformly distributed on the liquid crystal panel after reflection, refraction, and other processes, thereby achieving better uniformity.

[0037] As shown in Figure 1 The fixed frame 11 is provided with a first support assembly 111 for supporting the fixed frame 11, which enhances the stability and load-bearing capacity of the fixed frame 11, provides additional support for the fixed frame 11, and ensures that the fixed frame 11 remains stable when subjected to external loads or vibrations.

[0038] The first support assembly 111 can be fixed to the fixed frame 11 using welding, bolting, or other methods, and the structure of the fixed frame 11 is strengthened by the first support assembly 111, which can help the fixed frame 11 withstand greater weight or pressure, help distribute the force applied to the fixed frame 11 evenly, prevent local stress concentration, prolong the service life of the fixed frame 11, and reduce the risk of failure.

[0039] As shown in Figure 2 The top of the two fixed frames 11 is fixedly connected by sheet metal 112; the bottom frame 12 is provided with guide wheels 121, and the bottom frame 12 drives the movement of the conveying pallets through the guide wheels 121.

[0040] The top of the two fixed frames 11 is fixed together by sheet metal 112, which can ensure that the entire structure has good stability and anti-deformation ability under external forces or vibrations, ensuring the structural stability and rigidity between the two fixed frames 11.

[0041] Sheet metal 112 as a connecting piece can effectively combine two fixed frames 11 together, prevent relative displacement or distortion between them, thereby enhancing the stability of the overall structure; sheet metal 112 can provide additional support points for the overall structure of the conveying pallet, especially when subjected to external load, can evenly distribute the applied force, reduce local stress concentration; sheet metal 112 can be conveniently installed on the fixed frame 11 by welding, bolt connection and other methods, easy to disassemble and maintain, suitable for regular maintenance or adjustment, reduce manufacturing cost and installation difficulty.

[0042] The bottom frame 12 is internally provided with a guide wheel 121 for movement or positioning. When movement is needed, the guide wheel 121 drives the entire conveying pallet to move along the guide rail, which can reduce the friction between the conveying pallet and the guide rail, making movement more smooth and easy.

[0044] The bottom frame 12 is provided with two parallel insulating plastic plates 4, and the bottom of the insulating plastic plate 4 is provided with two parallel grooves.

[0045] As shown in Figure 5 , one end of the insulating plastic plate 4 is provided with a terminal block 6, and the terminal block 6 is embedded with a copper contact, and the copper bar 5 is connected through the copper contact; the copper contact is embedded in the cylindrical hole of the terminal block 6; by embedding the copper contact in the cylindrical hole of the terminal block 6 and electrically connecting with the copper bar 5, good electrical conductivity can be achieved without damaging the integrity of the insulating plastic plate 4.

[0046] As shown in Figure 6 , the support assembly 2 is fixed on the fixed frame 11 by edge folding, and the support assembly 2 is a high-temperature resistant plastic plate.

[0047] The support assembly 2 is made of high-temperature-resistant plastic plate, which can maintain its physical properties and functions in high-temperature environment, and is more suitable for high-temperature aging working environment; the support assembly 2 is fixed on the fixed frame 11 by means of edge folding, one side or more sides of the support assembly 2 are designed with curved or folded edges, which can realize stable placement of the liquid crystal panel; and the edge folding fixation usually does not require additional fasteners (such as screws, nuts, etc.), thereby simplifying the assembly process; if maintenance or replacement is required, the edge folding fixation allows relatively quick disassembly and reinstallation, reducing the need for other fasteners and possibly reducing overall costs; using high-temperature-resistant plastic plate as the material of the support assembly 2, combined with the edge folding fixation installation method, can work reliably in high-temperature conditions and provide a simple and stable installation solution.

[0048] As shown in Figure 7 , the conveying pallet is arranged on the guide rail 7, the guide rail 7 is provided with a speed-increasing chain 71, one end of the guide rail 7 is provided with a driving assembly 72, the driving assembly 72 drives the speed-increasing chain 71 to rotate, realizing the conveying of the pallet on the guide rail 7; the liquid crystal panel is placed on the conveying pallet, the conveying pallet is conveyed by the speed-increasing chain 71, and the liquid crystal panel is powered during the conveying process to perform high-temperature aging test.

[0049] Specifically, the guide rail 7 is used to support and guide the movement of the conveying pallet along a predetermined path; the speed-increasing chain 71 is installed inside the guide rail 7; the driving assembly 72 is located at one end of the guide rail 7 and is responsible for providing power for the speed-increasing chain 71, which drives the speed-increasing chain 71 to rotate, thereby realizing the movement of the conveying pallet along the guide rail 7; the driving assembly 72 usually includes a motor, a speed increaser and other necessary transmission components; the conveying pallet is placed on the guide rail 7 and is pushed or pulled by the speed-increasing chain 71 to move, and the liquid crystal panel is placed on the conveying pallet to perform high-temperature aging test during the conveying process, and the copper bar 5 supplies power to the liquid crystal panel while moving.

[0050] As shown in Figure 7 , the inner side of the guide rail 7 is provided with a blocking mechanism 73, the blocking mechanism 73 is a blocking air cylinder, the blocking air cylinder 73 is fixedly installed at one end of the guide rail 7 and is used to intercept the pallet to control the movement of the pallet.

[0051] The main function of the blocking air cylinder 73 is to intercept the conveying pallet to stop its movement, which can be realized by extending the piston rod of the air cylinder, the piston rod can be vertically or horizontally extended into the inside of the guide rail 7 to prevent the pallet from continuing to move forward; using the blocking air cylinder 73 as the blocking mechanism can quickly respond as needed and can withstand a certain impact force, and is relatively simple and reliable, with low maintenance cost, ensuring the safety and efficiency of the entire conveying process.
