Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a transfer device and transfer tool for battery preparation materials. Background Technology

[0002] Lithium-ion batteries have advantages such as high specific energy, high cycle life, and long storage time. They are widely used not only in portable electronic devices (such as mobile phones, digital cameras, and laptops), but also in large and medium-sized electric equipment such as electric vehicles, electric bicycles, and power tools.

[0003] In lithium-ion battery production, activities such as new material development, raw material inspection, experimental verification, anomaly analysis, and random sampling often require the production of button batteries (also known as coin cells) for testing and analysis. Some materials used in the production of button batteries (such as electrode sheets, separators, casings, spring contacts, and other battery preparation materials) need to be dried before use to control moisture content.

[0004] However, currently in the manufacturing process of button batteries, there are no dedicated containers for materials requiring drying (i.e., battery preparation materials). The materials are typically placed directly on mats or clamps and then dried in an oven. After drying, they are quickly transferred to a vacuum-sealed glove box to minimize the impact of moisture in the air. In actual operation, because the materials (i.e., battery preparation materials) are directly exposed to air during the transfer process (from removal from the oven until placement in the glove box), they absorb moisture, ultimately affecting the experimental results (i.e., the test and analysis results).

[0005] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a transfer device and tool for battery preparation materials.

[0007] Therefore, the present invention provides a transfer device for battery preparation materials, characterized in that it includes a hollow sealed device housing;

[0008] The device housing includes a hollow glass lower housing with an open top and horizontally distributed glass cover plates;

[0009] The top of the lower glass housing is detachably and sealed with a glass cover.

[0010] The inner cavity of the lower glass housing is used to hold battery preparation materials that need to be dried and transferred from the oven to the vacuum drying oven;

[0011] An elastic silicone sealing ring is provided around the bottom surface of the glass cover and the top perimeter of the lower glass housing.

[0012] The glass cover has two vertically penetrating circular one-way exhaust valve mounting holes;

[0013] A one-way vent valve is sealed and installed in each one-way vent valve mounting hole;

[0014] A one-way exhaust valve is used to prevent air from the outside of the device housing from flowing into the inner cavity of the device housing when the vacuum drying oven is venting, and to discharge air from the inside of the device housing to the outside of the device housing when the device housing is placed inside the oven for drying operation and / or when the device housing is placed inside the vacuum drying oven for drying operation, and is also used for the drying and transfer of battery preparation materials between the oven and the vacuum drying oven.

[0015] In addition, the present invention also provides a transfer tool for battery preparation materials, including at least one transfer device for battery preparation materials as described above;

[0016] The transport tool for the battery preparation materials is a mobile tool.

[0017] As can be seen from the technical solution provided by the present invention above, compared with the prior art, the present invention provides a transfer device and transfer tool for battery preparation materials. Its structure is scientifically designed and can realize the dry transfer of materials (i.e., battery preparation materials) between the oven and the glove box. It effectively avoids the materials from being directly exposed to the air during the transfer process (i.e., from the time they are taken out of the oven until they are placed in the vacuum-sealed glove box), prevents the materials from absorbing moisture from the air, and ensures the accuracy of experimental results (i.e., test and analysis results). It has significant practical significance. Attached Figure Description

[0025] See Figure 1 The present invention provides a transfer device for battery preparation materials, including a hollow sealed device housing;

[0026] The device housing includes a hollow glass lower housing 5 with an open top and horizontally distributed glass cover plates 3;

[0027] The top of the lower glass housing 5 is detachably and sealed with a glass cover plate 3;

[0028] The inner cavity of the lower glass housing 5 is used to place battery preparation materials (i.e., materials) that need to be dried and transferred from the oven to a vacuum drying oven (e.g., a vacuum-sealed glove box).

[0029] It should be noted that battery manufacturing materials (i.e., materials) can specifically include battery manufacturing materials such as electrodes, separators, casings, and spring contacts. Of course, depending on the user's needs, they can also be other materials that require drying and transportation.

[0030] An elastic silicone sealing ring 4 is provided around the bottom surface of the glass cover plate 3 and the top periphery of the lower glass housing 5.

[0031] The glass cover plate 3 is provided with two vertically penetrating circular one-way exhaust valve mounting holes 301;

[0032] A one-way exhaust valve 1 is sealed and installed on each one-way exhaust valve mounting hole 301;

[0033] One-way exhaust valve 1 is used to prevent air from the outside of the device housing from flowing into the inner cavity of the device housing when the vacuum drying oven (e.g., glove box) is leaking (i.e., not sealed), and to exhaust air from the inside of the device housing to the outside of the device housing when the device housing is placed inside the oven for drying operation and / or when the device housing is placed inside the vacuum drying oven for drying operation, and is used for the drying and transfer of battery preparation materials (i.e., materials) between the oven and the vacuum drying oven (e.g., glove box).

[0034] It should be noted that, in this invention, the one-way exhaust valve 1 is used to exhaust air into the external space in one direction when the drying operation is carried out in the vacuum drying oven, and to seal the entire device housing when the drying oven is venting air, thus maintaining a low-pressure, dry environment inside the device housing.

[0035] In this invention, specifically, both the lower glass housing 5 and the glass cover plate 3 are made of transparent glass.

[0036] In this invention, specifically, the two one-way exhaust valve mounting holes 301 are symmetrically distributed from left to right.

[0037] In this invention, specifically, a protective plate 302 (specifically a plastic protective plate, such as a polypropylene PP protective plate) is arranged around the glass cover plate 3.

[0038] A buckle 2 is provided at each of the left and right ends of the protective plate 302;

[0039] In practice, buckle 2 is a buckle that can be bent up and down at a certain angle, such as a polypropylene (PP) buckle.

[0040] Furthermore, on the upper ends of the left and right sides of the lower glass housing 5, there is a longitudinally distributed snap-fit ​​protrusion 501;

[0041] When both buckles 2 are in a vertically distributed state, the longitudinally distributed locking blocks at the lower ends of the opposite side of the two buckles 2 engage with the locking protrusion 501 (specifically: the locking blocks are located below the locking protrusion 501 and the top surface of the locking blocks is in close contact with the bottom surface of the locking protrusion 501).

[0042] Furthermore, the snap-fit ​​protrusion 501 is elongated, i.e., rectangular.

[0043] Furthermore, both the top surface of the card block and the bottom surface of the carding protrusion 501 are horizontally distributed planes.

[0044] Furthermore, the longitudinal length of the locking block is less than or equal to the longitudinal length of the locking protrusion 501.

[0045] Furthermore, the top surfaces of the two snap-fit ​​protrusions 501 are on the same horizontal plane;

[0046] The two snap-fit ​​protrusions 501 are symmetrically distributed on the left and right sides.

[0047] In practice, the protective plate 302 and the buckle 2 are integrally formed.

[0048] In practice, a buckle 2 is provided at the middle of the left and right ends of the guard plate 302.

[0049] It should be noted that, in this invention, PP clips are used to fasten the glass cover plate 3 and the lower glass housing 5, ensuring the sealing of the entire transfer device. The perforated glass cover plate 3 and the lower glass housing 5 together form a sealed space. The silicone sealing ring 4 is used to provide good contact between the glass cover plate 3 and the lower glass housing 5, ensuring internal sealing. The lower glass housing 5, as a container for holding materials, together with the glass cover plate 3, forms a sealed space.

[0050] Based on the battery preparation material transfer device provided by the present invention, the present invention also provides a battery preparation material transfer tool, which includes at least one battery preparation material transfer device as described above.

[0051] In this invention, specifically, the transport tool for battery preparation materials is a mobile tool, which can be any mobile tool, such as a van, truck, cargo truck, trailer, or drop trailer. This application does not strictly limit the type of mobile tool, and will not list them all here.

[0052] Compared with the prior art, the battery preparation material transfer device provided by the present invention has the following characteristics:

[0053] Beneficial effects:

[0054] 1. By using the transfer device for battery preparation materials designed in this invention, the drying transfer of materials to be dried can be realized between the oven and the drying box, which can provide better drying conditions for the materials (i.e., battery preparation materials, such as button cell battery preparation materials).

[0055] 2. This invention enables less material to come into contact with external air during the drying and transfer process, reducing the risk of material contamination;

[0056] 3. This invention can ensure the consistency of moisture content of the electrolytic capacitor material between different batches, improve the consistency of electrolytic capacitor data, and increase the success rate of electrolytic capacitor manufacturing;

[0057] 4. This invention can provide a drier gas environment for materials (i.e., battery preparation materials, such as coin cell battery preparation materials). Existing ordinary drying and transfer devices can only provide a dry environment with a relatively low degree of dryness. The drying environment provided by this invention depends on the drying capacity of the vacuum drying oven and the drying time of the oven, and can provide a higher degree of dryness.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
