[0034] This invention provides a technical solution: an all-solid-state battery transfer fixture, see [link / reference]. Figures 1 to 4 It includes a stacking platform 1 and a base plate 2. The base plate 2 is set on the stacking platform 1 by a positioning plate 4. The upper surface of the base plate 2 is connected to a pressure plate 3 by a locking member. The locking member can fix and separate the base plate 2 and the pressure plate 3. The side walls of the base plate 2 and the pressure plate 3 are provided with a first clamp clearance opening 5, which corresponds to the position where the battery stacked electrode tabs protrude.
[0035] Specifically, a battery stack is placed between the base plate 2 and the pressure plate 3 of this transfer fixture and secured by locking components, achieving glue-free clamping. Simultaneously, a first fixture clearance opening 5 is provided, which not only facilitates the transfer of the battery stack but also exposes the battery tabs for subsequent welding. The locking components allow for quick fixing and separation of the base plate 2 and the pressure plate 3 without the need for additional tools; the locking components may include, but are not limited to, quick-release clamps, knob latches, or screws.
[0036] As an optional implementation, in some embodiments, a pressing assembly is further provided on the stacking platform 1. The pressing assembly includes an electrode pressing blade 11, which is used to align the stacked electrodes. The electrode pressing blade 11 can precisely align the stacked electrodes, effectively preventing displacement or misalignment of the electrodes during the stacking process, ensuring the neatness and accuracy of the electrode stacking, thereby improving the quality and performance stability of the all-solid-state battery assembly.
[0037] As an optional implementation, in some embodiments, the sidewall of the positioning plate 4 is provided with a plurality of second clamp clearance openings 6, which are spaced apart along the length of the positioning plate 4. This design does not affect the positioning and support function of the positioning plate 4 on the base plate 2, and provides clearance space for other components, wiring, or tools that may be involved in the operation, avoiding mutual interference and making subsequent operations more convenient and flexible, thus improving overall usability and work efficiency.
[0038] As an optional implementation, in some embodiments, the upper surface of the positioning plate 4 is provided with a plurality of adsorption holes 7, and the side of the positioning plate 1 is provided with negative pressure air holes 8 communicating with the adsorption holes 7. The positioning plate 4 and the base plate 2 are fixedly connected by negative pressure. This design not only ensures a stable and reliable connection, guaranteeing that the base plate 2 remains in a stable position during operation, reducing shaking or displacement and improving the accuracy of battery transfer and assembly, but also facilitates quick disassembly and installation via negative pressure connection, allowing for flexible adjustments according to actual production needs and contributing to improved production efficiency.
[0039] As an optional implementation, in some embodiments, magnets are respectively provided on the upper surface of the positioning plate 4 and the lower surface of the base plate 2, and the positioning plate 4 and the base plate 2 are magnetically connected. This design makes installation and disassembly extremely convenient, allowing for quick fixation and separation of the positioning plate 4 and the base plate 2 without complex operations, significantly improving production efficiency. Simultaneously, the magnetic connection provides a relatively stable and reliable adsorption force, ensuring that the base plate 2 and the positioning plate 4 are tightly fitted during battery transfer and assembly, effectively reducing errors caused by shaking or displacement.
[0040] As an optional implementation, in some embodiments, threaded holes are provided on the positioning plate 4 and the base plate 2, and the positioning plate 4 and the base plate 2 are fixedly connected by screws. This design provides a robust and reliable connection, ensuring a tight fit between the positioning plate 4 and the base plate 2 during the transfer and assembly of the all-solid-state battery, effectively preventing relative movement and ensuring operational accuracy. Simultaneously, the screw connection method is versatile, low-cost, and relatively simple to install and disassemble, facilitating maintenance of the fixture, replacement of components, or flexible adjustments according to different production needs, thus contributing to improved production efficiency and reduced production costs.
[0041] As an optional implementation, in some embodiments, the locking element is a quick-release clamp 9, which is fixed to the base plate 2 and the pressure plate 3 by means of positioning pins 10 respectively. Using the quick-release clamp 9 as the locking element, and fixing the base plate 2 and the pressure plate 3 by means of positioning pins 10, makes the fixing and separation of the base plate 2 and the pressure plate 3 extremely convenient and efficient, allowing for rapid clamping and releasing actions, greatly shortening operation time and improving production efficiency. At the same time, the positioning pins 10 accurately determine the installation position of the quick-release clamp, ensuring that the base plate 2 and the pressure plate 3 are accurately aligned each time they are fixed, improving the accuracy and stability of the fixing.
[0042] As an optional implementation, in some embodiments, the locking element is a screw, and threaded holes are provided on the edges of the base plate 2 and the pressure plate 3. The screw is fixed in place by threaded engagement with the threaded holes. This design is simple and low-cost, as screws and threaded holes are common and readily available components, effectively controlling production costs. Simultaneously, the screw connection provides high stability, ensuring a tight fit between the base plate 2 and the pressure plate 3 during the transfer and assembly of the all-solid-state battery, reducing shaking and misalignment. Furthermore, installation and disassembly can be achieved simply by rotating the screw, making operation convenient and allowing for flexible adjustment or maintenance of the pressure plate 3 and the base plate 2 according to actual production conditions.
[0043] As an optional implementation, in some embodiments, the locking element is a knob latch, which includes a matching groove and a protrusion. The upper surface of the base plate 2 has a groove, and the lower surface of the pressure plate 3 has a protrusion. When the protrusion engages with the groove, rotating the pressure plate 3 locks it onto the base plate 2. Using a knob latch as the locking element, the groove on the upper surface of the base plate 2 matches the protrusion on the lower surface of the pressure plate 3, and rotating the pressure plate achieves locking. This design is simple and quick to operate, allowing for rapid fixing and separation of the base plate 2 and the pressure plate 3 without the need for additional tools, significantly improving work efficiency. Simultaneously, the locking structure provides a relatively stable and reliable connection, ensuring that the pressure plate 3 and the base plate 2 are tightly fitted during the transfer and assembly of the all-solid-state battery, effectively reducing errors caused by shaking or displacement, and ensuring production quality.
[0044] As an optional implementation, in some embodiments, both the base plate 2 and the pressure plate 3 are plate-shaped structures. The plate-shaped structure has a larger planar contact area, which can more evenly distribute pressure when fixing the all-solid-state battery, avoiding excessive localized stress and damage to the battery, thus ensuring battery quality. At the same time, the larger planar surface also facilitates cooperation and installation with other components, such as precise docking with positioning plates and locking devices, improving the assembly accuracy and stability of the entire transfer fixture, thereby increasing the efficiency and reliability of the battery transfer and assembly process.
[0045] The working principle of this transfer fixture is as follows: The base plate 2 is placed on the positioning plate 4 of the stacking platform 1, and the base plate 2 is firmly held in place by negative pressure adsorption through the adsorption holes 7 on the positioning plate 4 to prevent displacement. The automatic stacking equipment uses the base plate 2 as a reference to precisely stack the positive electrode sheet, solid electrolyte membrane, and negative electrode sheet in sequence. The electrode pressing blade 1 in the pressing assembly constrains the electrode sheets, ensuring a high degree of alignment. After stacking, the electrode pressing blade 1 retracts, and the base plate 2 is equipped with positioning pins 10, which can be aligned with the quick-pressing device 9 on the pressing plate 3 to position and press the electrode. The pressing plate 3 applies a small and uniform pre-pressure through the quick-pressing device 9, initially pressing the entire cell stack. Finally, the entire transfer fixture (base plate + cell + pressing plate) can be safely transported as a whole to subsequent welding, packaging, and other processes.
