Description

Technical Field

[0001] This utility model relates to the field of solid-state battery technology, specifically to a sealed transition chamber for transporting solid-state battery electrode rolls. Background Technology

[0002] In the current era of rapid development in the new energy industry, solid-state batteries, with their high energy density, wide operating temperature range, and excellent safety performance (no risk of liquid electrolyte leakage or thermal runaway), have become the core development direction for next-generation power batteries and energy storage batteries. The core processes of solid-state battery electrode roll production, storage, cutting, and roll-to-roll assembly all need to be completed within an inert gas-protected glove box. However, in actual mass production scenarios, electrode rolls need to be transferred between multiple glove boxes with different functions. This transfer process becomes a critical link in compromising the inert environmental protection of the electrode rolls. If the glove box door is opened directly for electrode roll transfer, water and oxygen from the outside atmosphere will instantly penetrate the glove box, not only causing an imbalance in the inert environment inside the box but also contaminating the surface of the electrode rolls, leading to batch product defects.

[0003] A Chinese patent with publication number CN205674233U discloses a portable sealed transfer chamber, comprising a cover and a body. The cover engages with the opening of the body. The cover includes an outer cover, an inner cover, and a drive mechanism. The outer cover is detachably connected to the body. The inner cover is located between the outer cover and the body. The drive mechanism drives the inner cover to move between a first position and a second position. In the first position, the inner cover is sealed to the opening of the body. In the second position, the inner cover is separated from the opening of the body.

[0004] Existing technologies are unsuitable for transferring electrode rolls between multiple glove boxes, resulting in complex transfer processes, poor adaptability, and high maintenance costs. Therefore, there is a need for a sealed transition chamber for transferring solid-state battery electrode rolls that is simple in structure, convenient to transfer, highly adaptable, and improves transfer efficiency while ensuring transfer stability.

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] like Figure 1As shown, a sealed transition chamber for transporting solid-state battery electrode rolls according to this utility model includes: a chamber body 1 and a transfer vehicle 2. A moving device is provided at the bottom of the chamber body 1, allowing the chamber body 1 to move between multiple glove boxes via the moving device. A sealed door is provided on the front of the chamber body 1, matching the doors of the glove boxes. An accommodating space is formed inside the chamber body 1. The transfer vehicle 2 is disposed inside the chamber body 1. One or more ventilation ports 11 are provided on the sealed chamber body 1. A set of parallel tracks is provided on the bottom plate inside the chamber body 1. 12, and the bottom of the transfer vehicle 2 is provided with a set of moving wheels 21 that match the track. The cabin 1 and / or the transfer vehicle 2 are equipped with a drive device. The transfer vehicle 2 can be driven by the drive device to move along the direction of the track 12 to the outside of the cabin 1. The transfer vehicle 2 is provided with a fixed frame 22. The fixed frame 22 is equipped with a fixed rod 23 that matches the shaft hole of the pole roll. The fixed rod 23 is horizontally set and is located in the middle of the accommodating space of the cabin 1. The pole roll does not contact the fixed frame 22 or the inner wall of the cabin 1.

[0021] A positioning ring 231 is provided at one end of the fixing rod 23 near the fixing frame 22, and a limit ring 232 is movably installed at the other end of the fixing rod 23. The limit ring 232 can move along the axial direction of the fixing rod 23. The electrode roll shaft is fixed to the fixing rod 23 by the cooperation of the positioning ring 231 and the limit ring 232, which can fully ensure the stability of the electrode roll during transportation. When the transfer vehicle 2 transfers the electrode roll, the limit ring 232 is first removed, then the position of the transfer vehicle 2 is adjusted so that the fixing rod 23 is aligned with the electrode roll mounting shaft inside the glove box, then the electrode roll is moved directly onto the fixing rod 23, and finally the limit ring 232 is installed on the fixing rod 23 to ensure the stability of the electrode roll. In the transfer of some electrode rolls, the electrode roll itself is heavy and will not move easily during the movement, so the limit ring 232 may not be used for fixation.

[0022] Generally, the dimensions of the fixing rod 23 are consistent with those of the pole roll mounting shaft. If they are inconsistent, a fixing rod 23 of a different size can be used. To facilitate the adjustment of the fixing rod 23, multiple mounting positions can be set on the fixing frame 22, or a lifting device can be set on the fixing frame 22. Generally, a cylinder-type lifting device can be used. A cylinder-type lifting device is usually composed of a cylinder body, piston, sealing ring, piston rod, and other components. The piston rod pushes the fixing rod 23 to rise and fall to the appropriate position.

[0023] Guide blocks 121 are provided on both sides of the track 12 near the sealed door. Generally, for ease of movement, the moving wheel assembly 21 uses casters. To ensure the moving wheel assembly 21 accurately enters the track 12, guide blocks 121 are provided on both sides of the track 12 near the sealed door to guide the movement direction of the moving wheel assembly 21. A positioning block 122 is provided at the end of the track 12 away from the sealed door. Anti-collision strips corresponding to the transfer vehicle 2 are provided on the inner wall of the cabin 1. Through the dual protection of the positioning block 122 and the anti-collision strips, it is ensured that the transfer vehicle 2 will not collide with the cabin 1. Generally, the transfer vehicle 2 equipped with a polar roller is heavier and moves at a slower speed, allowing for rapid braking and reducing the likelihood of collision; therefore, the anti-collision structure can be omitted.

[0024] The movable wheel set 21 is equipped with a self-locking device, which fixes the movable wheel set 21 to the track 12. The self-locking device can be an electromagnetic self-locking device, i.e., an electronically controlled lock. It uses an electromagnetic coil to generate magnetic force, which attracts the brake block or pin to achieve locking. When the power is cut off, the magnetic force disappears, the spring returns to its original position, and the lock is unlocked, which helps to achieve automated production.

[0025] To achieve flexible movement of the transfer vehicle 2, the drive unit can be directly mounted on it, typically using an electric or hydraulic drive. The servo driver of the electric drive receives control signals, drives the servo motor, and the encoder provides real-time feedback on speed / position, achieving closed-loop control. The motor of the hydraulic drive drives a hydraulic pump to generate high-pressure oil, which is distributed to the hydraulic motor / cylinder through hydraulic valves, driving the wheels. Speed ​​regulation is achieved by adjusting the opening of the hydraulic valves to control the oil flow. In other applications, a drive unit can also be installed on the cabin 1, such as in straight-in / straight-out operating environments, allowing the transfer vehicle 2 to quickly and accurately return to track 12. For example, a pneumatic drive unit, using compressed air as a power source, transmits power through cylinders or a pneumatic motor, suitable for light-load, short-distance, and oil-free scenarios, offering low cost and simple maintenance.

[0026] The transfer cart 2 is equipped with an automatic start-stop device and / or a handle is installed on the fixed frame 22. To further improve automated production, an automatic start-stop device can be installed on the transfer cart 2, such as a sensor- and control system-based automatic start-stop device. This device typically uses multiple sensors, such as speed sensors and position sensors, to monitor the operating status of the transfer cart. These sensors can be installed on both sides of the track 12. When the transfer cart 2 reaches a designated position or meets specific conditions, the sensors send signals to the control system. The control system determines whether to stop or start the transfer cart 2 according to a preset program and logic. To simplify the transfer cart 2 or facilitate manual operation, a handle can be directly installed on the fixed frame 22, allowing the transfer cart 2 to be moved manually by pulling or pushing.

[0027] The sealed hatch includes a door frame and a door panel. The door frame is covered with a sealant and protrudes outwards from the hatch body 1. The hatch body 1 is sealed to the glove box door via the door frame. Hinges connecting the door frame and door panel are located at the top or sides of the door panel. A pneumatic actuator is installed on the sealed hatch door, driving the door panel outwards. The bottom of the door frame smoothly connects to the bottom of the glove box door. The bottom movement device of the hatch body 1 includes casters or sliders; when the movement device is a slider, a matching track is laid on the ground.

[0028] Ventilation vents 11 are located on the back or side of the chamber 1, and are separated from the pole roll by a fixing bracket 22. Generally, two ventilation vents 11 are provided, one for exhaust and one for intake. By exhausting air and introducing inert gas, and closing the ventilation vents 11, the chamber 1 is kept in an inert gas state. During transport, the chamber 1 maintains an inert state at all times. After docking with the glove box, the environments are identical, ensuring the stability of the pole roll's condition.

[0029] This application incorporates a transfer cart 2 within the cabin 1. After the cabin 1 is docked with the glove box, the transfer cart 2 can move into the glove box to transfer the electrode rolls from the glove box into the cabin 1. This eliminates the need for docking with the cabin 1 via equipment, preventing collisions between the electrode rolls and the cabin walls, thus ensuring stable transfer. The transfer cart 2's flexible movement and adjustable fixing rod 23 allow this application to handle the transfer of various electrode rolls, significantly improving adaptability, transfer efficiency, and production efficiency, thereby reducing production costs.
