Description

Technical Field

[0001] The utility model relates to the field of optical product transportation, and more specifically, to a portable light-shielding transportation fixture. Background Art

[0002] As one of the representative products in the field of augmented reality (AR), holographic waveguide has unique diffraction optical properties, which give it significant advantages in achieving wide viewing angles, high transparency, and thin and light structures. However, the realization of these advantages is inseparable from a sophisticated and strict production process, including key steps such as spraying and lamination, light-shielding transfer, and holographic exposure. Holographic exposure is a crucial link, which determines the quality of the grating structure and the transmission efficiency of light waves. Before holographic exposure, the material light-shielding requirements are extremely high, because any unnecessary light source may affect the photosensitive film, thereby affecting the final imaging effect and product performance.

[0003] In the existing holographic waveguide production process, semi-finished products are mostly transported by carts during the transfer process. This traditional transfer method has obvious shortcomings: first, the semi-finished products are exposed to the air during the transfer process and are easily affected by the external environment, such as dust and humidity, which may have an adverse effect on the performance of the product, and ensuring the cleanliness of the transfer environment increases the complexity and cost of the production process; secondly, the shading effect of the cart transfer method is not good, and it is easy to be contaminated by light sources and damage the performance of the spraying material; finally, only using carts for transportation will result in a short temporary storage time for the semi-finished products.

[0004] The above factors directly lead to a decrease in product yield, so it is necessary to improve the existing transfer method to improve the production efficiency and production yield of holographic optical waveguides and enhance market competitiveness. Utility Model Content

[0005] The utility model aims to overcome at least one of the deficiencies of the above-mentioned prior art and provides a portable light-shielding transfer fixture for solving the problem of sealing and light-shielding transfer of semi-finished products.

[0006] The technical solution adopted by the utility model is to provide a portable light-shielding transport fixture, including a box body, a box door, a handle, a slot and a support plate, wherein the box body and the box door are sealed and connected, the handle is located at the top of the box body, the slot is transversely arranged on the side wall of the box body, the two sides of the support plate are slidably engaged in the slot, and the inner and / or outer surfaces of the box body and the box door are coated with a light-shielding material layer. The holographic optical waveguide is placed on the support plate, sealed in the box body, and protected by the light-shielding material, isolating the influence of the external environment, preventing the material from being exposed to light before the holographic optical waveguide is exposed, and avoiding gas or dust pollution, thereby ensuring safe transportation and long temporary storage time.

[0007] Furthermore, a receiving groove is provided on the pallet, the thickness of the pallet is 1.5 to 3 cm, and the ratio of the depth of the receiving groove to the thickness of the pallet is 1:(2 to 20). The holographic optical waveguide is placed in a receiving groove that matches its shape, which is beneficial to prevent it from sliding and colliding during transportation and causing damage. The thickness of the pallet itself is controlled at 1.5 to 3 cm. Such a thickness design not only ensures the rigidity of the pallet, enabling it to bear the weight of the holographic optical waveguide, but also facilitates the operation of the operator. The receiving groove has a certain depth, so that the holographic optical waveguide is partially or completely located in the receiving groove, which is beneficial to avoid the vibration of the box during transportation causing the holographic optical waveguide to slip out of the receiving groove.

[0008] In order to solve the problem of collision during the disassembly and assembly of the pallet, the four corners of the pallet are chamfered, and the distance between adjacent pallets and between the pallet and the upper and lower walls of the box is 2 to 3 cm. The above design not only facilitates the operator to insert the pallet into the card slot in the forward or reverse direction, reducing the difficulty of operation, but also effectively avoids collision between the pallet and the box or other pallets during the disassembly and assembly process, thereby protecting the holographic optical waveguide from damage.

[0009] In order to enhance the shading effect, the utility model adopts Teflon as the shading material, not only because of its excellent sealing performance, it can effectively isolate the external light and ensure that the holographic optical waveguide is not affected by the light before exposure, but also because of its excellent weather resistance, it can maintain a stable shading effect under various environmental conditions, thereby extending the temporary storage time of the holographic optical waveguide in the box.

[0010] To ensure safe transportation, one side of the box door is connected to the box body by a hinge, and the other side is connected to the box body by a lock, which is convenient for operation and prevents the box door from opening when the box falls.

[0011] Furthermore, the top of the box is provided with a groove for accommodating the handle, the base of the handle is provided with a folding shaft, and the lower surface of the box is provided with an anti-skid pad. The handle can be folded and placed in the groove, and the anti-skid pad prevents the box from sliding and colliding, so as to facilitate the stacking and transportation of multiple boxes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The portable light-shielding transfer jig provided by the utility model isolates the influence of the external environment through light-shielding materials and complete sealing, prevents the material from being exposed to light before the holographic optical waveguide is exposed, and avoids gas or dust pollution; the box with an internal card slot prevents the holographic optical waveguide from being damaged by collision, and facilitates safe transportation. Compared with existing transfer jigs such as carts, it has significant advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Both sides of the support plate 4 are installed in the card slot 3. The inner and outer surfaces of the box body 1 and the box door are covered with a light-shielding material layer. During the transportation process, the holographic optical waveguide is placed on the support plate 4, sealed in the box body 1, and protected by the light-shielding material, isolated from the external environment, and the material is prevented from being exposed to light before the holographic optical waveguide is exposed, and gas or dust pollution is avoided, thereby ensuring safe transportation and long temporary storage time.

The above design not only facilitates the operator to insert the support plate 4 into the card slot 3 in the forward or reverse direction, reducing the difficulty of operation, but also effectively avoids collision between the support plate 4 and the box body 1 or other support plates 4 during the disassembly and assembly process, thereby protecting the holographic optical waveguide from damage.

[0023] In order to enhance the shading effect, the utility model adopts Teflon as the shading material, not only because of its excellent sealing performance, it can effectively isolate the external light and ensure that the holographic optical waveguide is not affected by the light before exposure, but also because of its excellent weather resistance, it can maintain a stable shading effect under various environmental conditions, thereby extending the temporary storage time of the holographic optical waveguide in the box 1.
