Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a glove box, an electrolyte production line, and a battery production line. Background Technology

[0002] In the battery production process, electrolyte preparation is usually required. When preparing electrolyte, metal salts and other powders need to be poured into the powder injector first, and the powder injector will add powder. However, when filling the powder injector, the powder is easy to spill and contaminate the non-powder filling area. Utility Model Content

[0003] The main purpose of this invention is to propose a glove box, an electrolyte production line, and a battery production line, which aims to reduce the risk of powder contamination of other work areas during the powder filling process.

[0004] To achieve the above objectives, the glove box proposed in this utility model includes:

[0005] The housing has a mounting cavity;

[0006] A powder filling box, wherein the powder filling box is disposed in the mounting cavity and has an inner cavity, and the powder filling box has a first material outlet for communicating with the inner cavity and the mounting cavity; and

[0007] The hatch is closable and located at the first material inlet.

[0008] This application isolates an independent inner cavity within the box body as a powder filling space by setting a powder filling box inside the box body. The inner cavity and the mounting cavity outside the powder filling box can be connected through a first material outlet on the powder filling box, so that the powder injector can be transferred between the inner cavity and the mounting cavity through the first material outlet. The powder injector that needs to be filled first enters the mounting cavity and then enters the inner cavity through the first material outlet; the powder injector that has finished filling first enters the mounting cavity and then is sent to the outside of the glove box; and when it is not necessary to transfer the powder injector, the first material outlet is closed through the hatch to reduce the risk of powder in the inner cavity entering the mounting cavity, thereby reducing the risk of powder in the inner cavity entering the non-powder filling area of ​​the glove box and the external environment of the glove box, and also reducing the risk of powder being contaminated and deteriorated.

[0009] In one embodiment, the glove box further includes a first conveying assembly disposed in the mounting cavity and located outside the inner cavity, with a portion of the first conveying assembly located outside the first material inlet.

[0010] Using the above method, the powder injector that needs to be fed into the inner cavity can be conveyed to the first material outlet position in the installation cavity through the first conveying component; the powder injector that is sent out from the inner cavity can also be conveyed to the discharge position of the box through the first conveying component, so that the powder injector can be automatically transferred in the installation cavity, improving the convenience of use.

[0011] In one embodiment, the glove box further includes a top-feeding assembly, which is disposed corresponding to the first material outlet. The top-feeding assembly includes:

[0012] A lifting structure, which is vertically adjustable and has a first position and a second position, wherein when the lifting structure is in the first position, a portion of the lifting structure is higher than the material loading track of the first conveying assembly; and when the lifting structure is in the second position, the lifting structure is lower than the material loading track.

[0013] A first drive structure is configured to drive the lifting structure to rise and fall.

[0014] Using the above method, when the powder injector is conveyed to the first feed port position by the first conveying component, the top material component can lift the powder injector, which can prevent the powder injector from continuing to be driven by the first conveying component and move, so as to facilitate the picking and placing of the powder injector.

[0015] In one embodiment, the inner cavity is provided with a powder injector placement area, a powder placement area, and an operation area. The powder injector placement area is corresponding to the first material outlet, and the operation area is located on the side of the powder injector placement area away from the first material outlet.

[0016] Using the above method, the powder injector placement area is set between the operation area and the first feed port. Powder injectors that need to be filled with powder or have already been filled with powder can be placed in the powder injector placement area adjacent to the first feed port. The operation flow is smooth, which can reduce the movement path of the powder injector and facilitate the picking and placing of the powder injector.

[0017] In one embodiment, the glove box further includes a material handling component disposed in the powder filling box, the material handling component being configured to transfer the powder injector at the first material outlet.

[0018] By using the above method, the powder injector is transferred between the mounting cavity and the inner cavity through the material handling component, thereby improving the level of automation and ease of use.

[0019] In one embodiment, the material handling assembly includes:

[0020] A material support structure, wherein the material support structure is telescopically configurable and can pass through the first material inlet to extend into the mounting cavity; and

[0021] A second drive structure is configured to drive the material support structure to extend and retract.

[0022] Using the above method, when there is no need to pick up or put down the powder injector, the material support structure is located in the inner cavity. When it is necessary to transfer the powder injector from the mounting cavity to the inner cavity, the material support structure extends from the first material outlet to enter the mounting cavity. The powder injector can be supported on the material support structure and sent to the powder injector placement area when the material support structure retracts into the inner cavity. Similarly, when it is necessary to transfer the powder injector from the inner cavity to the mounting cavity, the material support structure extends from the first material outlet to send the powder injector out. The operation is simple, and the method of using the material support structure to support the powder injector makes the powder injector more stable during the transfer process and less prone to tipping over.

[0023] In one embodiment, the glove box further includes an operating platform located in the operating area, and the second drive structure is located below the operating platform.

[0024] Using the above method, the space below the operating platform can be used to install the second drive structure. The internal structure is compactly arranged, the space utilization rate is high, which helps to reduce the size of the powder filling box, thereby reducing the volume of the entire glove box.

[0025] In one embodiment, the edge of the operating area is provided with a limiting structure.

[0026] This setup utilizes a limiting structure to restrict the movement of devices placed in the operating area, reducing the risk of devices slipping off the operating area.

[0027] In one embodiment, the powder placement area is provided with a powder support; this arrangement, where the powder container is placed on the powder support, can reduce the risk of the powder container shifting or tipping over.

[0028] And / or, the inner cavity is provided with at least two powder placement areas, which are distributed around the periphery of the operating area; this arrangement can make full use of the space in the inner cavity, and the at least two powder placement areas can hold multiple powder containers, thereby increasing the powder storage capacity in the glove box; the powder placement areas are located around the periphery of the operating area, which facilitates the handling of powder during operation.

[0029] In one embodiment, the box body is provided with a first opening communicating with the mounting cavity, and the glove box further includes a first transition compartment, which is located outside the box body and covers the first opening.

[0030] Using the above method, the powder injector can enter and exit the installation cavity via the first transition chamber; the first transition chamber can be used to ensure the stability of the internal environment of the box and can further reduce the risk of powder escaping to the external environment of the glove box.

[0031] In one embodiment, the powder filling box is provided with a second material passage, and the box body is provided with a second opening opposite to the second material passage;

[0032] The glove box also includes a second transition compartment, which is located outside the box body and covers the second opening.

[0033] With this design, powder containers and filling tools can enter and exit the inner cavity through the second feed port, and the second transition chamber prevents the inner cavity from being directly connected to the external environment, thereby reducing the risk of powder spilling from the inner cavity into the external environment.

[0034] In one embodiment, the glove box further includes a second conveying assembly disposed between the second transition chamber and the powder filling box.

[0035] This setup allows powder containers and filling tools to be transferred via a second conveyor assembly, improving automation and ease of use.

[0036] In one embodiment, the hatch is liftable; this configuration allows the hatch to open and close without taking up too much space and is easy to operate.

[0037] In one embodiment, the glove box further includes a third drive structure configured to drive the hatch to open and close.

[0038] This configuration eliminates the need for manual control of the hatch opening and closing, improving automation and ease of use.

[0039] In one embodiment, the glove box further includes an infrared lamp disposed in the inner cavity.

[0040] This setup allows infrared lamps to irradiate the inner cavity, achieving a heating and drying effect and reducing the impact of trace amounts of water in the glove box on the powder.

[0041] In one embodiment, the inner cavity is provided with a grinding assembly and a screen.

[0042] This setup allows for grinding and sieving of powders within the inner cavity, resulting in uniform particle size.

[0043] This application also proposes an electrolyte production line, including a glove box as described in any of the foregoing embodiments.

[0044] By installing the aforementioned glove box on the electrolyte production line for filling the powder injector, the risk of powder spilling into non-filling areas of the glove box and the external environment during the filling process can be reduced, and the powder is less likely to be contaminated.

[0045] This application also proposes a battery production line, including an electrolyte production line as described in any of the foregoing embodiments.

[0046] The above description is only an overview of the technical solution of this application.

[0060] In the battery production process, electrolyte preparation is usually required. When preparing electrolyte, metal salts and other powders need to be poured into the powder injector first, and the powder injector will add powder. However, when filling the powder injector, the powder is easy to spill and contaminate the non-powder-filled area, and the powder is also easy to be contaminated and deteriorate.

[0061] Based on the above considerations, this utility model proposes a glove box 100, which can reduce the risk of powder contamination of the external environment during the powder filling process.

[0062] Please see Figure 1In one embodiment of the present invention, the glove box 100 includes a box body 10, a powder filling box 20 and a door 30. The box body 10 is provided with an installation cavity 11. The powder filling box 20 is disposed in the installation cavity 11 and is provided with an inner cavity 21. The powder filling box 20 is provided with a first material outlet 22 for connecting the inner cavity 21 and the installation cavity 11. The first material outlet 22 is openable and closable.

[0063] In this embodiment, the glove box 100 includes a box body 10 and a powder filling box 20 disposed within the box body 10. The powder filling box 20 divides the internal space of the box body 10 into an installation cavity 11 located outside the powder filling box 20 and an inner cavity 21 located inside the powder filling box 20. One side wall of the box body 10 is provided with a glove opening, and a sealed glove provided at the glove opening extends into the inner cavity 21, so that the operator can insert both hands into the inner cavity 21 for operation. Optionally, the powder filling box 20 and the box body 10 may share a portion of the side wall, or the side wall of the powder filling box 20 may be spaced apart from the side wall of the box body 10.

[0064] The housing 10 is provided with an inlet and outlet for connecting the mounting cavity 11 to the external environment; optionally, an outlet and an inlet can be provided on the housing 10, or only one opening can be provided on the housing 10 for the powder injector to enter and exit. The powder filling box 20 is provided with a first material passage 22 for connecting the inner cavity 21 and the mounting cavity 11. In specific applications, the powder injector can be transferred between the inner cavity 21 and the mounting cavity 11 through the first material passage 22. The powder injector that needs to be filled first enters the mounting cavity 11, and then enters the inner cavity 21 through the first material passage 22; the powder injector that has completed filling in the inner cavity 21 first enters the mounting cavity 11 through the first material passage 22, and then is sent to the outside of the glove box 100.

[0065] The glove box 100 also includes a movable door 30. When the powder dispenser does not need to be transferred, the door 30 closes the first material outlet 22 to reduce the risk of powder in the inner cavity 21 entering the mounting cavity 11, thereby reducing the risk of powder escaping to the external environment of the glove box 100. Optionally, the door 30 can slide open and close, so that the door 30 is slidably connected to the side wall of the powder filling box 20 and can slide along the side wall of the powder filling box 20, so that the sliding door 30 opens or closes the first material outlet 22. The door 30 can also be rotated open and closed, so that the door 30 is rotatably connected to the powder filling box 20, so that rotating the door 30 opens or closes the first material outlet 22. Optionally, the door 30 can be manually controlled by the operator, or it can be automatically controlled by a third drive structure; this is not limited here.

[0066] In other words, this application provides a powder filling box 20 inside the box 10 of the glove box 100, thereby isolating an independent inner cavity 21 within the box 10 as a powder filling space. When powder filling is required, the powder filling box 20 is closed through the hatch 30, which can prevent powder from spilling into the non-powder filling area outside the powder filling box 20 during the powder filling process. Furthermore, the inner cavity 21 is not directly connected to the external environment of the glove box 100, which also reduces the risk of powder in the inner cavity 21 entering the external environment of the glove box 100 and causing environmental pollution, and also reduces the risk of powder being contaminated and deteriorated.

[0067] In some embodiments, the powder injector is placed on the powder injector bracket 105 to move between the glove box 100 and the external environment, and between the mounting cavity 11 and the inner cavity 21. By placing the powder injector on the powder injector bracket 105, multiple powder injector mounting positions can be provided on the powder injector bracket 105 to hold multiple powder injectors, thereby enabling the simultaneous transfer of multiple powder injectors and improving efficiency; in addition, it can improve the stability of the powder injector during the transfer process and reduce the risk of powder injector misalignment and tipping. Optionally, the multiple powder injector mounting positions provided on the powder injector bracket 105 can be configured to hold different types of powder injectors, for example, by providing multiple limiting holes or limiting grooves of different sizes to accommodate powder injectors of various sizes.

[0068] Optionally, the glove box 100 may also be equipped with an indicator light 103, which can be used to determine whether a powder filling operation or other operation is being performed in the glove box 100 by the illumination status of the indicator light 103; for example, the indicator light 103 is illuminated when a powder filling operation is being performed; the indicator light 103 may also emit a different color of light or flash when the powder dispenser is being transferred; the indicator light 103 is turned off when no operation is being performed in the glove box 100.

[0069] Please see Figure 2 and Figure 4 In one embodiment, the glove box 100 further includes a first conveying assembly 40, which is disposed in the mounting cavity 11 and located outside the inner cavity 21, with a portion of the first conveying assembly 40 located outside the first material outlet 22.

[0070] In this embodiment, a first conveying assembly 40 is provided in the mounting cavity 11 of the housing 10. Optionally, the first conveying assembly 40 can be configured as, but is not limited to, a belt conveyor assembly, a roller conveyor assembly, a robot arm, or other structures. The first conveying assembly 40 is configured to convey the powder injector, which can transport the powder injector fed into the mounting cavity 11 to the first feed port 22 position, so as to send the powder injector to the inner cavity 21; the powder injector sent out from the inner cavity 21 can also be conveyed to the discharge position of the housing 10 by the first conveying assembly 40, thereby automatically transferring the powder injector in the mounting cavity 11, improving the convenience of use.

[0071] Please see Figure 2 and Figure 4 In one embodiment, the first conveying assembly 40 is provided with a plurality of conveying rollers 41 arranged side by side.

[0072] In this embodiment, the first conveying component 40 is configured as a roller conveying component, including multiple conveying roller shafts 41. The conveying roller shafts 41 are rotatably configured and can be connected by a synchronous chain to drive the multiple conveying roller shafts 41 to rotate synchronously. With this configuration, the first conveying component 40 has a simple structure, high reliability, and is easy to maintain.

[0073] Please see Figures 3 to 5 In one embodiment, the glove box 100 further includes a top material assembly 50, which is provided corresponding to the first material passage 22. The top material assembly 50 includes a lifting structure 51 and a first drive structure 52. The lifting structure 51 is vertically adjustable and has a first position and a second position. When the lifting structure 51 is in the first position, a portion of the lifting structure 51 is higher than the material loading track of the first conveying assembly 40. When the lifting structure 51 is in the second position, the lifting structure 51 is lower than the material loading track. The first drive structure 52 is configured to drive the lifting structure 51 to move up and down.

[0074] In this embodiment, the glove box 100 further includes a top-loading assembly 50, which includes a lifting structure 51 and a first drive structure 52 for driving the lifting structure 51 to rise and fall. The lifting structure 51 can be configured as, but is not limited to, a rod-shaped structure, a block-shaped structure, etc. The first drive structure 52 can be configured as a cylinder or electric cylinder lifting structure, or as a combination of a drive motor and a transmission mechanism, such as a drive motor and a lead screw transmission mechanism, or a motor and a rack and pinion transmission mechanism, etc., without limitation.

[0075] Optionally, the lifting structure 51 can be located on the side of the first conveying assembly 40, such that the width of the material loading track of the first conveying assembly 40 is relatively small, for example, smaller than the powder injector bracket 105 used to place the powder injector, so that part of the structure of the powder injector bracket 105 extends from both sides of the material loading track and corresponds to the lifting structure 51; the lifting structure 51 moves up and down on the side of the first conveying assembly 40 to lift the powder injector bracket 105 or place the powder injector bracket 105 on the first conveying assembly 40.

[0076] In some embodiments, the first conveying assembly 40 may also be configured as a roller conveying assembly, which includes a plurality of conveying rollers 41 arranged side by side, and the lifting structure 51 may pass through two adjacent conveying rollers 41 to rise to a position above the conveying rollers 41.

[0077] In practical applications, when the powder injector is conveyed to the first feed port 22 by the first conveying component 40, the top material component 50 can lift the powder injector, which can prevent the powder injector from continuing to be driven by the first conveying component 40 to move, so as to facilitate the picking and placing of the powder injector.

[0078] Please see Figure 3 In one embodiment, the inner cavity 21 is provided with a powder injector placement area 25, a powder placement area 26 and an operation area 24. The powder injector placement area 25 is correspondingly arranged with the first material outlet 22, and the operation area 24 is located on the side of the powder injector placement area 25 away from the first material outlet 22.

[0079] In this embodiment, the inner cavity 21 is divided into a powder injector placement area 25, a powder placement area 26, and an operation area 24. The powder injector placement area 25 is used to place the powder injector, the powder placement area 26 is used to place the powder container, and the operation area 24 serves as the area for filling the powder injector with powder. In some embodiments, the operation area 24 can also be used for powder grinding, sieving, and other operations. The powder injector placement area 25 is located between the operation area 24 and the first feed port 22. Powder injectors that need to be filled or have already been filled can be placed in the powder injector placement area 25 adjacent to the first feed port 22. This streamlined operation reduces the movement path of the powder injector and facilitates the placement and removal of the powder injector.

[0080] See also Figure 2 and Figure 3 In one embodiment, the glove box 100 further includes a material handling assembly 60, which is disposed in the powder filling box 20 and is configured to transfer the powder injector at the first material outlet 22.

[0081] In this embodiment, the glove box 100 is provided with a material picking component 60 located on the powder filling box 20. When it is not necessary to move the powder injector into or out of the inner cavity 21, the material picking component 60 is located in the inner cavity 21. When it is necessary to move the powder injector into or out of the inner cavity 21, the powder injector is transferred between the mounting cavity 11 and the inner cavity 21 by the material picking component 60, thereby improving the degree of automation and ease of use.

[0082] Optionally, the material handling assembly 60 may be equipped with a retractable material support structure 61, or it may be configured as a clamping structure such as a robotic arm that can move in and out of the inner cavity 21. Optionally, in some embodiments, the powder injector is placed on the powder injector support 105 for transfer. In this case, the material handling assembly 60 may be configured to directly pick up the powder injector on the powder injector support 105 to transfer the powder injector, or it may be configured to transfer the entire powder injector support 105. No limitation is made here.

[0083] Please see Figure 3In one embodiment, the material handling assembly 60 includes a material support structure 61 and a second drive structure 62. The material support structure 61 is telescopically oriented and can pass through the first material inlet 22 to extend into the mounting cavity 11. The second drive structure 62 is configured to drive the material support structure 61 to extend and retract.

[0084] In this embodiment, the material handling assembly 60 includes a retractable material support structure 61 that can extend and retract into the inner cavity 21, and a second drive structure 62 for driving the material support structure 61 to extend and retract. The material support structure 61 can be configured as, but is not limited to, a tray, a material support arm, or other structures. The second drive structure 62 can be configured as an electric cylinder or a pneumatic cylinder, or as a combination of a motor and a transmission mechanism, such as a motor and a lead screw transmission mechanism, or a motor and a rack and pinion transmission mechanism, etc., and is not limited here.

[0085] In practical applications, the powder injector is placed on the powder injector support 105. When there is no need to pick up or put down the powder injector, the material support structure 61 is located in the inner cavity 21. When it is necessary to transfer the powder injector from the mounting cavity 11 to the inner cavity 21, the material support structure 61 extends from the first material outlet 22 to enter the mounting cavity 11, and the powder injector support 105 is supported on the material support structure 61 and sent to the powder injector placement area 25 when the material support structure 61 retracts into the inner cavity 21. Similarly, when it is necessary to transfer the powder injector from the inner cavity 21 to the mounting cavity 11, the material support structure 61 extends from the first material outlet 22 to send out the powder injector support 105. The operation is simple, and by using the material support structure 61 to support the powder injector support 105, the powder injector support 105 is relatively stable during the transfer process and is not easy to tip over.

[0086] Please see Figure 3 In some embodiments, the mounting cavity 11 is provided with a material lifting assembly 50 for lifting the powder injector. Two sets of material lifting assemblies 50 can be provided at intervals. When the powder injector support 105 is raised, the material supporting structure 61 can extend into the area between the two material lifting assemblies 50 to support the powder injector support 105.

[0087] Please see Figure 3 In one embodiment, the glove box 100 further includes an operating platform 70, which is located in the operating area 24, and the second drive structure 62 is located below the operating platform 70.

[0088] In this embodiment, the glove box 100 also includes an operating platform 70 disposed in the inner cavity 21. An operating area 24 is formed on the operating platform 70. There is a hollow space below the operating platform 70. The second drive structure 62 is placed in the hollow space below the operating platform 70, so that the structure in the inner cavity 21 is compact and the space utilization rate is high. This is beneficial to reduce the size of the powder filling box 20, thereby reducing the volume of the entire glove box 100.

[0089] Please see Figure 3and Figure 6 In one embodiment, a limiting structure 71 is provided at the edge of the operating area 24. The limiting structure 71 may be configured as, but is not limited to, a limiting strip, a limiting block, or other structures. The limiting structure 71 can be used to limit the devices placed on the operating area 24, reducing the risk of the devices sliding out of the operating area 24.

[0090] Please see Figure 3 and Figure 6 In one embodiment, the glove box 100 further includes a powder support 104, which is placed in the powder placement area 26 for holding powder containers. Optionally, the powder support 104 is provided with a limiting hole or a limiting groove, and the powder container is placed in the limiting hole or the limiting groove, which can reduce the risk of the powder container shifting and tipping.

[0091] Optionally, the powder holder 104 is provided with multiple mounting positions for placing multiple powder containers. Different powder containers can be used to hold different types of powder, so that it is not necessary to repeatedly replace the powder in the inner cavity 21.

[0092] Please see Figure 3 and Figure 6 In one embodiment, at least two powder placement areas 26 are provided in the inner cavity 21, and the at least two powder placement areas 26 are distributed around the periphery of the operating area 24. This arrangement can make full use of the space in the inner cavity 21, and the at least two powder placement areas 26 can hold multiple powder containers, thereby increasing the powder storage capacity in the glove box 100; the powder placement areas 26 are located around the periphery of the operating area 24, which facilitates the handling of powder during operation.

[0093] Please see Figure 1 In one embodiment, the box body 10 is provided with a first opening communicating with the mounting cavity 11, and the glove box 100 also includes a first transition chamber 80, which is located outside the box body 10 and covers the first opening.

[0094] In this embodiment, a first opening is provided on the housing 10 for the powder injector to enter and exit the mounting cavity 11, and a first transition chamber 80 is provided covering the outside of the first opening. The powder injector can enter and exit the mounting cavity 11 through the first transition chamber 80. The first transition chamber 80 can ensure the stability of the internal environment of the housing 10 and further reduce the risk of powder escaping to the external environment of the glove box 100. The first transition chamber 80 is provided with an inner door and an outer door. The inner door can be used to separate the mounting cavity 11 of the housing 10 from the internal space of the first transition chamber 80, and the outer door can be used to separate the internal space of the first transition chamber 80 from the external environment. When it is necessary to transfer the powder injector, the inner door and the outer door can be opened. Optionally, the inner and outer chamber doors can be opened separately. For example, when transferring the powder injector between the housing 10 and the first transition chamber 80, the outer chamber door can be closed and the inner chamber door can be opened. When transferring the powder injector between the first transition chamber 80 and the external environment, the inner chamber door can be closed and the outer chamber door can be opened, thereby preventing the installation cavity 11 from communicating with the external environment, reducing the risk of contamination of the installation cavity 11 and the inner cavity 21, and also reducing the risk of powder entering the external environment.

[0095] Optionally, in some embodiments, the glove box 100 is further provided with a gas replacement structure. This structure is configured to evacuate and fill the first transition chamber 80 with an inert gas (such as nitrogen or argon), effectively replacing the air within the first transition chamber 80 to ensure that the atmosphere within the first transition chamber 80 is consistent with the atmosphere of the mounting cavity 11. This prevents outside air from entering the mounting cavity 11 and the inner cavity 21, thus avoiding disruption of the specific anhydrous, oxygen-free, or dust-free environment. In some embodiments, the powder injector can be placed into the first transition chamber 80 first, the outer door closed, and then the evacuation and filling operations performed. Finally, the inner door is opened to move the powder injector into the mounting cavity 11.

[0096] Please see Figure 1 In one embodiment, the powder filling box 20 is provided with a second material passage 23, which is located on different side walls of the powder filling box 20 and the first material passage 22. The box body 10 is provided with a second opening opposite to the second material passage 23. The glove box 100 also includes a second transition chamber 90, which is located on the outside of the box body 10 and covers the second opening.

[0097] In this embodiment, the powder filling box 20 is provided with a second material outlet 23 for powder containers and powder filling tools to enter and exit the inner cavity 21. Correspondingly, a second opening is provided on the box body 10 opposite to the second material outlet 23, and a second transition chamber 90 is provided covering the second opening. Powder containers and powder filling tools can enter and exit the box body 10 through the second transition chamber 90 and enter and exit the inner cavity 21 through the second material outlet 23. With the provision of the second transition chamber 90, the inner cavity 21 will not be directly connected to the external environment through the second material outlet 23, thereby reducing the risk of powder in the inner cavity 21 spilling into the external environment.

[0098] The second transition chamber 90 is equipped with an inner door and an outer door. The inner door separates the internal space of the inner cavity 21 and the second transition chamber 90, while the outer door separates the internal space of the second transition chamber 90 from the external environment. When it is necessary to transfer powder containers and powder filling tools, the inner and outer doors can be opened. Optionally, the inner and outer doors can be opened separately. For example, when transferring powder containers and powder filling tools between the housing 10 and the second transition chamber 90, the outer door is closed and the inner door is opened. When transferring powder containers and powder filling tools between the second transition chamber 90 and the external environment, the inner door can be closed and the outer door opened, thereby preventing the inner cavity 21 from communicating with the external environment, reducing the risk of contamination of the installation cavity 11 and the inner cavity 21, and also reducing the risk of powder entering the external environment.

[0099] Optionally, in some embodiments, the glove box 100 is further provided with a gas replacement structure. This structure is configured to evacuate and fill the second transition chamber 90 with an inert gas (such as nitrogen or argon), effectively replacing the air inside the second transition chamber 90. This ensures that the atmosphere inside the second transition chamber 90 is consistent with the atmosphere of the mounting cavity 11 and the inner cavity 21, thereby preventing outside air from entering the mounting cavity 11 and the inner cavity 21 and avoiding disruption of the specific anhydrous, oxygen-free, or dust-free environment. In some embodiments, the powder injector can be placed into the second transition chamber 90 first, the outer chamber door closed, and then the evacuation and filling operations performed. Finally, the inner chamber door is opened to move the powder container and powder filling tools into the box 10.

[0100] Please see Figure 1 and Figure 2 In one embodiment, the glove box 100 further includes a second conveying assembly 101, which is disposed between the second transition chamber 90 and the powder filling box 20.

[0101] In this embodiment, the glove box 100 further includes a second conveying assembly 101 for transferring powder containers and powder filling tools between the second transition chamber 90 and the powder filling box 20. The second conveying assembly 101 may be configured as, but is not limited to, a belt conveyor assembly, a roller conveyor assembly, etc. With this configuration, powder containers and powder filling tools can be transferred through the second conveying assembly 101, improving the level of automation and ease of use.

[0102] In one embodiment, the hatch 30 is liftable; this configuration means that the hatch 30 does not require much space to open or close and is easy to operate.

[0103] In one embodiment, the glove box 100 further includes a third drive structure configured to drive the hatch 30 to open and close.

[0104] In this embodiment, a third drive structure is provided to drive the opening and closing of the door 30, eliminating the need for manual control and improving automation and ease of use. Optionally, the third drive structure can be configured according to the movement mode of the door 30. For example, the door 30 can be slidably connected to the powder filling box 20, and the opening and closing of the door 30 can be achieved by sliding the door 30. In this case, the third drive structure can be configured as, but is not limited to, a cylinder or electric cylinder push structure, a motor lead screw structure, etc. Alternatively, the door 30 can be rotatably connected to the powder filling box 20, and the opening and closing of the door 30 can be achieved by rotating the door 30. In this case, the third drive structure can be configured as, but is not limited to, a rotary motor or cylinder structure.

[0105] In one embodiment, the glove box 100 further includes an infrared lamp disposed in the inner cavity 21.

[0106] In this embodiment, an infrared lamp is installed in the inner cavity 21. The infrared lamp can be used to irradiate the inner cavity 21 to achieve the function of heating and drying, which can reduce the impact of trace amounts of water in the glove box 100 on the powder and reduce the risk of powder deterioration.

[0107] In one embodiment, the inner cavity 21 is provided with a grinding assembly and a screen.

[0108] In this embodiment, grinding components and screens can be installed in the inner cavity 21 to grind and sieve the powder. This can solve the problem of inconsistent particle size of the incoming powder, so that the powder particles are uniform in size. This reduces the risk of powder blockage and jamming when the powder injector is used for powder injection.

[0109] Optionally, a powder receiving tray can be set on the operating area 24, and powder filling, grinding and sieving operations can be carried out on the powder receiving tray, so that the powder spilled during the powder filling, grinding and sieving process can be collected on the powder receiving tray, making it easy to clean the powder.

[0110] This application also proposes an electrolyte production line, including a glove box 100 as described in any of the foregoing embodiments. The specific structure of the glove box 100 is as described in the above embodiments. By setting the glove box 100 on the electrolyte production line, the powder injector can be filled with powder in the inner cavity 21 of the glove box 100. This reduces the risk of powder spilling into the inner cavity during the filling process and entering the non-filling area of ​​the glove box 100 or the external environment of the glove box 100, and the powder is less likely to be contaminated.

[0111] Since this electrolyte production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0112] This application also proposes a battery production line, including the electrolyte production line as described in the foregoing embodiments.
