Description

Technical Field

[0001] This utility model relates to the field of production equipment protection technology, and in particular to an equipment shield for lithium-ion battery cathode material production equipment. Background Technology

[0002] The production process of lithium-ion battery cathode materials, involving steps such as mixing, sintering, and conveying, requires extremely high environmental cleanliness. Production equipment typically needs observation windows or protective enclosures to monitor internal conditions and isolate the equipment from the external environment. Tempered glass, due to its transparency and strength, is often used for such protective enclosures. However, tempered glass shatters into numerous fine particles upon impact or spontaneous breakage. In the cathode material production environment, which is extremely sensitive to particulate contaminants, these glass fragments, if they detach from the protective enclosure and enter the production area, will cause serious product contamination and economic losses. Existing technologies using tempered glass alone as a protective enclosure cannot completely eliminate this risk.

[0003] Therefore, there is an urgent need for an equipment shielding solution that can ensure that tempered glass fragments do not fall off and pollute the environment after breakage, while meeting the specific structural and performance requirements of the production environment. Utility Model Content

[0004] The purpose of this invention is to provide a device shield that can prevent glass fragments from falling off, has a reasonable structure, reliable performance, and is suitable for the production environment of cathode materials.

[0005] This utility model provides a device shield for the production of positive electrode materials. The shield includes a first side protection part fixedly connected to an outer rail, a second side protection part disposed relative to the first side protection part, and a top protection part connected to the top of the first side protection part and the second side protection part.

[0006] The first side protection section, the second side protection section, and the top protection section are all assembled and connected from several protective panel units; wherein, the protective panel unit includes:

[0007] The frame contains tempered glass, and at least one surface of the tempered glass is covered with an explosion-proof film.

[0008] Optionally, the explosion-proof film is adhered to the inner surface of the tempered glass.

[0009] Optionally, the shield is a top-opening shield; the top protective part includes at least one protective panel unit that can be rotated and opened and closed around a first pivot, the first pivot being perpendicular to the outer rail.

[0010] Preferably, the protective panel unit that can be rotated and opened / closed about a first pivot is hinged to the frame of an adjacent protective panel unit.

[0011] Optionally, the shield is a side-linked opening shield; the shield includes at least a rigid opening component that can be rotated and opened and closed around a second pivot. The rigid opening component is formed by a protective panel unit of the second side protective part and a protective panel unit of the adjacent top protective part, and the second pivot is parallel to the outer rail.

[0012] Optionally, the rigid opening component is L-shaped, and the second pivot is a hinge fixed to the top of the first side protective part. The rigid opening component is hinged to the top of the first side protective part through the second pivot.

[0013] Alternatively, the frame can be constructed by splicing together aluminum alloy square tubes.

[0014] Optionally, the explosion-proof film is selected from special films that can withstand high temperatures of 120-250℃.

[0015] Optionally, a silicone sealing gasket is installed between the frames of adjacent protective panel units.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] This invention provides a protective shield for equipment used in the production of cathode materials. It is installed on the outer rail of a lithium-ion battery cathode material production line. Its basic structure includes a first-side protective portion 71 fixedly connected to the outer rail, a second-side protective portion 72 disposed relative to the first-side protective portion 71, and a top protective portion 6 connected to the top of the first-side protective portion 71 and the second-side protective portion 72. The first-side protective portion 71, the second-side protective portion 72, and the top protective portion 6 are all assembled from one or more protective panel units. This modular design allows for the combination of various protective shield types as needed on the production line. For example, top-opening shields (such as...) can be used in combination depending on the manual operation method and the size of the lithium battery material container. Figure 1 (as shown), side-linked opening mask (such as) Figure 2(as shown) and a fully sealed fixed shield (such as Figure 3 (This is part of the illustration, intended for areas where no human intervention is required.)

[0032] Reference Figure 1 , Figure 2 , Figure 3 Each protective panel unit is a basic building block of the shield. It contains a frame 1, within which a piece of tempered glass 2 is installed.

[0033] Frame 1 preferably uses aluminum alloy square tubing as the skeleton material for splicing. During splicing, four aluminum alloy square tubing can be preferably joined to form a quadrilateral structure, with both ends of each tubing beveled to form a beveled surface. The beveled surfaces of adjacent tubing are mirror-symmetrically joined. The connection method at the splice can be welding, bonding, or fixed installation using connectors. Using aluminum alloy reduces the frame's weight, and the beveled surface splicing method ensures a strong connection and high load-bearing capacity; for example, with proper design, the overall load-bearing capacity can reach approximately 500 kg. Aluminum alloy itself is lightweight and corrosion-resistant. Silicone sealing gaskets can be placed between the frames of adjacent protective panel units. These silicone sealing gaskets effectively prevent the generation of metal foreign particles due to friction between metal parts, and also prevent these particles from falling into lithium battery products with extremely high cleanliness requirements.

[0034] Frame 1 can be designed with a narrow bezel, for example, by selecting aluminum alloy square tubing with a smaller cross-section or optimizing the connection structure, so that the obstruction of the view of tempered glass 2 by frame 1 is minimized, ensuring that the ratio of the effective visible area defined by frame 1 on each protective panel unit to the total area of ​​tempered glass 2 is greater than or equal to 95%. This, combined with the lightweight characteristics of the aluminum alloy frame, makes the shield body lightweight and with minimal obstruction of the view, which is convenient for manual operation and equipment maintenance, and also makes it easy to manually monitor the operation of equipment inside the protective shield.

[0035] Tempered glass 2 is preferably made of single-layer tempered glass. Single-layer tempered glass is less prone to discoloration due to environmental factors (such as oxidation), has a relatively wear-resistant surface that is less prone to scratches, and can maintain high transparency over a long period, ensuring the observation function of the protective cover. At the same time, tempered glass has good high-temperature resistance, making it suitable for the high-temperature environments that may exist when lithium battery materials are first manufactured. Furthermore, using single-layer tempered glass is less expensive than other complex glass structures, helping to save on manufacturing and subsequent maintenance costs.

[0036] At least one surface of the tempered glass 2 is covered with an explosion-proof film 3. Preferably, the explosion-proof film 3 is adhered to the inner surface of the tempered glass 2 facing the inside of the equipment. It should be noted that this inner surface refers to the side of the tempered glass 2 facing the space shielded by the equipment cover. This protects the explosion-proof film 3 from external physical damage and ensures that, in the event of glass breakage, fragments primarily adhere to the inner surface. The explosion-proof film 3 uses a special film that ensures high light transmittance and abrasion resistance while also withstanding high temperatures such as 120-250°C. More importantly, when the tempered glass 2 shatters due to spontaneous breakage or impact from a heavy object, the strong adhesion of the explosion-proof film 3 firmly adheres all resulting glass fragments to its own surface, effectively reducing or even eliminating the risk of glass fragments falling into the production materials, thereby ensuring the safety and purity of the lithium battery materials. Furthermore, the explosion-proof film 3 is pasted on the inner surface of the tempered glass 2 facing the inside of the equipment. Even if the adhesion of the explosion-proof film 3 is insufficient, it can still catch the glass fragments from below when the tempered glass 2 is broken due to spontaneous explosion or impact from a heavy object.

[0037] When multiple independent shielding units (regardless of whether they are open or fixed) need to be assembled side-by-side or in series to form a continuous protective area, universal rubber-silicone sealing gaskets can be installed at the joints between the frames 1 of adjacent shielding units. These silicone sealing gaskets can prevent external foreign objects (such as dust and moisture) from entering the protected area, and also help to ensure the relative stability of the internal environment (such as dew point) of the protected area.

[0038] The overall structure and opening method of the mask:

[0039] Protective panel units can be connected and combined in different ways to form equipment shields with specific functions.

[0040] Fixed connection (refer to) Figure 3 (Illustrative): Adjacent protective panel units can be fixedly connected by sharing a frame 1 component or using connectors (such as bolts, angle brackets, etc.) to form a fixed part of the shield, such as a fixed sidewall or top cover. This form is suitable for areas that do not require frequent opening, forming a fully sealed protection.

[0041] Top-opening mask (see reference) Figure 1The top protective section 6 consists of a fixed top protective panel unit 61 and at least one protective panel unit 62 that can be rotated and opened / closed around a first pivot. The protective panel unit 62 that can be rotated and opened / closed around the first pivot is a complete protective panel unit, with one side of its frame 1 hinged to the fixed top protective panel unit 61 via a first pivot 51 perpendicular to the outer rail. In this embodiment, the first pivot 51 can be a component that can rotate about a direction perpendicular to the outer rail, such as a hinge positioned perpendicular to the outer rail. The hinge can be fixed to the frame 1 of an adjacent fixed top protective panel unit 61 or to a frame used to support the main body of the shield. Thus, the user can easily flip up this protective panel unit 62 that can be rotated and opened / closed around the first pivot for operations such as equipment maintenance or material addition.

[0042] Side-mounted, linked opening visor (see reference) Figure 2 The cover provides a large opening that opens in a linked manner. The cover includes at least one rigid opening assembly that can rotate and open / close around a second pivot 52. This rigid opening assembly is formed by a protective panel unit of the second side protective portion 72 and a protective panel unit of the adjacent top protective portion 6. The second pivot 52 is parallel to the outer rail. Specifically, the top of the first side protective portion 71 is fixedly connected to one side of its adjacent top protective portion 6, forming a rigid "L"-shaped opening assembly. The second pivot 52 is a hinge. The other edge of the top protective portion 6 of this rigid opening assembly is hinged to the top frame 1 of the second side protective portion 72 via multiple hinges. A handle 4 is provided on the bottom frame 1 of the first side protective portion 71. During operation, pulling the handle 4 upwards causes the entire L-shaped rigid opening assembly to flip open around the hinge axis, simultaneously exposing the top and the area covered by the first side, facilitating a wider range of operation or maintenance.

[0043] This invention effectively solves the core problem of contamination caused by broken glass fragments in the protective cover of equipment during cathode material production. It utilizes a high-performance explosion-proof film adhered to a single layer of tempered glass, combined with a modular frame design using aluminum alloy square tubing and wear-resistant silicone pads. It also prevents metal friction contamination. Furthermore, it offers flexible structural design options (fixed, top-opening, side-linked opening) and the possibility of combined use. Optional features include high-temperature resistant film, narrow frame, and silicone sealing gaskets. The design boasts advantages such as lightweight construction, high visibility, high safety, convenient operation and maintenance, and cost-effectiveness, effectively meeting the stringent requirements of cathode material production environments for safety, cleanliness, ease of operation, and environmental adaptability.
