[0002] In the field of semi-solid-state battery cell production, existing processes generally employ multiple machines, including die-cutting machines, stacking machines, short-circuit testing equipment, X-ray testing equipment, and thermal lamination equipment, operating in separate steps. Each step requires independent equipment connected by a high-speed chain or AGV. However, this model has many drawbacks: in multi-layer stacking, large-capacity cells often have more than 100 layers, and misalignment of a single electrode or separator can lead to rework and scrap of the entire cell. Disassembly can also cause secondary damage to the electrodes. The Z-type folding stacking process is cumbersome, and abnormalities at a single station can easily cause downtime or scrap of the entire cell, resulting in low efficiency and yield. At the same time, existing testing methods cannot detect 100% of defects such as misalignment and duplicates, and defects can easily flow into subsequent processes or even to the customer, posing safety hazards. In addition, a single high-speed die-cutting machine requires 4-5 stacking machines to match the production capacity, the equipment occupies a large area and has poor linkage; the thermal bonding pressure of bare cells is uneven and the heat conduction is slow, resulting in poor effect; it has extremely high requirements for environmental cleanliness and particles and burrs, once a short circuit occurs, it cannot be repaired and can only be scrapped, resulting in high production costs and poor product consistency.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] like Figure 1-3 As shown, the present invention provides a high-speed cutting, coating and stacking integrated machine for semi-solid battery cells, including a closed-loop conveying mechanism, a high-speed die-cutting module of sequential continuous closed-loop conveying mechanism, a defect detection module, a single-cell thermal coating module and a multi-station stacking module.
[0026] The equipment uses a continuous closed-loop conveyor mechanism as its core transmission carrier, connecting a high-speed die-cutting module, a defect detection module, a single-cell thermal bonding module, and a multi-station stacking module in series. A central control system enables synchronous operation of all modules. During the conveying process, the electrode sheets and cells are clamped and protected by PET clamping components throughout, ensuring conveying stability and preventing displacement or damage.
[0027] The high-speed die-cutting module is used to laser cut the semi-solid positive electrode sheet 4 and the semi-solid negative electrode sheet 5 into single electrode sheets of a preset size; the defect detection module is used to perform online defect detection on the single electrode sheets and screen out defective electrode sheets; the single cell thermal bonding module is used to preheat and roll-bond qualified single electrode sheets with the semi-solid electrolyte membrane 1 to form a single cell; the multi-station stacking module is used to stack the single cells layer by layer to form a bare cell; the continuous closed-loop conveying mechanism is equipped with a PET clamping assembly, which is used to clamp the electrode sheets or cells during the conveying process to prevent displacement.
[0028] Qualified individual battery cells are transported to the stacking station via a closed-loop system. At each stacking station, a positioning platform achieves precise positioning using positioning slots that match the shape of the individual battery cells. A cell pushing component then pushes the individual cells into the positioning slots for layer-by-layer stacking. A stacking height detection component monitors the stacking height in real time and feeds it back to the central control system, ensuring accurate and controllable stacking layers. The multi-station design allows for parallel processing of different batches of battery cells, improving stacking efficiency.
[0029] This embodiment adopts a process of "single electrode inspection, single cell lamination, and layer-by-layer stacking". Only defective single electrodes or single cells need to be removed, avoiding the scrapping of the entire cell due to single-layer defects, and greatly reducing material waste and rework costs.
[0030] Continuous closed-loop conveying replaces traditional point-and-click transmission, simplifying the stacking process and reducing process waiting time; multi-module linkage control (electrical connection between the drive motor and each module drive unit) enables high-speed coordination, solving the problem of mismatched production capacity where a single die-cutting machine needs to be equipped with 4-5 stacking machines; multi-station stacking modules operate in parallel, further improving stacking efficiency.
[0031] This embodiment employs a dual online detection mechanism combining "CCD visual inspection + X-ray penetration inspection" to identify visible defects on the electrode surface and hidden defects within the electrode in real time. Defective products are then immediately removed using a defect rejection component, thus blocking the transmission of defects at the source and reducing the safety risks to the battery cell.
[0032] In this embodiment, the preheating component 2 precisely controls the temperature (fluctuation ±5℃) to ensure uniform preheating of the electrode and the separator; the elastic hot press roller 3 uses elastic deformation to achieve uniform pressure transmission in each layer; PET-assisted lamination improves the consistency of pressure distribution; the adhesion of the semi-solid electrode (elastic deformation rate 5%-15%, adhesion strength 0.3-0.8N / cm) works synergistically with the semi-solid electrolyte layer of the separator to strengthen the interfacial bonding between the electrode and the separator, forming a stable conductive network.
[0033] In this embodiment, the PET clamping assembly replaces the traditional gripper / negative pressure adsorption, reducing electrode burrs and damage; the single-cell lamination and stacking reduces the exposure time of the bare cells and reduces the impact of environmental particles on the product; the semi-solid material system itself improves the tolerance of the cells to minor defects and reduces the risk of short circuit and scrapping.
[0034] This embodiment integrates the core processes of cutting, covering, and stacking into one unit, and achieves module interconnection through a continuous closed-loop conveying mechanism, which greatly reduces the number of equipment and the space occupied; the linkage and control of the central control system further improves the compactness and controllability of the production process.
[0035] Furthermore, the high-speed die-cutting module includes a symmetrically arranged positive laser cutting unit and a negative laser cutting unit. Both the positive and negative laser cutting units include an unwinding assembly, a tension adjustment assembly, and a laser cutting assembly. The cutting accuracy of the laser cutting assembly is not less than ±0.05mm.
[0036] Symmetrically arranged positive / negative laser cutting units process the input semi-solid positive electrode sheet 4 and semi-solid negative electrode sheet 5, respectively. After the electrode sheet is released by the unwinding assembly, the tension is maintained by the tension adjustment assembly, and then the laser cutting assembly (cutting accuracy ±0.05mm) cuts it into single electrode sheets of preset size to meet the electrode sheet size requirements of different battery cell specifications.
[0037] Furthermore, the defect detection module includes a CCD vision inspection unit and an X-RAY testing unit arranged sequentially along the conveying direction; the CCD vision inspection unit is used to detect burrs, wrinkles, and dimensional deviations of the electrode sheet; the X-RAY testing unit is used to detect hidden defects and thickness uniformity inside the electrode sheet; the defect detection module also includes a defect rejection component, which is electrically connected to the CCD vision inspection unit and the X-RAY testing unit, and is used to reject the detected defective electrode sheets from the conveying path.
[0038] After cutting, the individual electrode sheets are fed into the inspection stage by a closed-loop conveyor mechanism. First, a CCD vision inspection unit scans the surface of the electrode sheet to identify visible defects such as burrs, wrinkles, and dimensional deviations. Then, an X-ray testing unit penetrates the electrode sheet to detect hidden defects (such as uneven internal structure) and thickness uniformity. Defective electrode sheets detected are automatically removed from the conveyor path by a defect rejection component to prevent them from flowing into subsequent processes.
[0039] Furthermore, the single-cell thermal bonding module includes a preheating component 2 and a roll bonding component arranged sequentially along the conveying direction; the preheating component 2 is used to simultaneously preheat the qualified single-cell electrode and the semi-solid electrolyte membrane 1, with a preheating temperature of 60-120℃; the roll bonding component includes elastic hot press rollers 3 arranged symmetrically on the upper and lower sides, the surface of the elastic hot press rollers 3 is covered with an elastic layer, the temperature of the elastic hot press rollers 3 is 80-150℃, and the rolling pressure is 0.5-2MPa.
[0040] The preheating component 2 includes an infrared heating unit and a temperature sensing unit. The temperature sensing unit is electrically connected to the infrared heating unit and is used to monitor and adjust the preheating temperature in real time, with a temperature fluctuation range not exceeding ±5℃.
[0041] Qualified single-electrode plates and semi-solid electrolyte membrane 1 enter the module simultaneously. The preheating component 2 first preheats the electrode plate and membrane to 60-120℃ through the infrared heating unit. The temperature sensing unit monitors and adjusts the temperature in real time (fluctuation ±5℃) to ensure uniform preheating.
[0042] Furthermore, the PET clamping assembly includes a PET film unwinding roller, a PET recycling roller, and a clamping drive unit arranged opposite each other. The PET film output by the PET film unwinding roller is bonded to the upper and lower surfaces of the electrode sheet or battery cell. The clamping is achieved by applying a pre-tightening force through the clamping drive unit. The PET recycling roller is used to rewind and recycle the used PET film.
[0043] After the PET film is output from the unwinding roller, it is bonded to the upper and lower surfaces of the electrode / cell, and clamped by applying pre-tension force through a clamping drive. The used PET film is then wound up and reused by a recycling roller. The elastic deformation characteristics of PET can help to uniformly transmit pressure during subsequent roll lamination, while reducing electrode damage caused by grippers or negative pressure adsorption.
[0044] Furthermore, the multi-station stacking module includes at least two stacking stations, each of which includes a positioning platform, a cell pushing component, and a stacking height detection component; the positioning platform is provided with a positioning slot that matches the shape of a single cell; the cell pushing component is used to push the single cell delivered to the stacking station into the positioning slot; the stacking height detection component is used to monitor the stacking height in real time and feed it back to the control system.
[0045] The continuous closed-loop conveying mechanism includes a closed-loop conveyor belt, a drive motor, and multiple guide rollers. The conveying speed of the closed-loop conveyor belt is 0.5-2 m / s. The drive motor is electrically connected to the drive units of the high-speed die-cutting module, the defect detection module, the single-cell thermal bonding module, and the multi-station stacking module to realize the linkage control of each module.
[0046] The semi-solid positive electrode 4 and semi-solid negative electrode 5 are prepared by a semi-solid homogenization process, which results in an elastic deformation rate of 5%-15% and a bonding strength of 0.3-0.8 N / cm for the electrode. The surface of the semi-solid electrolyte membrane 1 is coated with a semi-solid electrolyte layer with a thickness of 5-20 μm.
[0047] The battery then enters the roll forming assembly, where heat and pressure are applied by symmetrical upper and lower elastic hot press rollers 3 (surface covered with an elastic layer, temperature 80-150℃, pressure 0.5-2MPa). By utilizing the adhesiveness of the semi-solid electrode and the semi-solid electrolyte layer of the separator (thickness 5-20μm), the electrode and separator are tightly bonded together to form a single battery cell.
[0048] Furthermore, the system also includes a central control system, which is electrically connected to the high-speed die-cutting module, defect detection module, single-cell thermal bonding module, multi-station stacking module, and continuous closed-loop conveying mechanism. This central control system receives detection data from each module and controls the operating parameters of each module. It receives real-time detection data from each module (such as defect information, temperature, pressure, stacking height, etc.) and dynamically adjusts laser cutting parameters, preheating temperature, roller pressure, and conveying speed (0.5-2 m / s) to ensure parameter matching and stable operation throughout the entire process.
[0049] In summary, the semi-solid electrode slurry process gives the electrode a certain degree of elasticity and adhesion, effectively avoiding electrode misalignment caused by subsequent thermal bonding process, while greatly improving the thermal bonding effect of the electrode, so that the positive and negative electrodes and the separator form a good conductive network, improving the battery's safety, rate capability, internal resistance, consistency and cycle life.
[0050] The coating of the semi-solid electrolyte membrane 1 and the application of semi-solid homogenization technology enable the electrode and the membrane to be coated through multiple processes and multiple levels of new technology applications and innovations, which greatly improves the battery's consistency, safety, wide temperature range and cycle performance.
[0051] The multi-layer lamination is changed to single-cell lamination, and only a single cell is scrapped, so the entire cell will not be scrapped.
[0052] Through the transmission and subsequent PET clamping process, the PET and the electrode have a certain degree of adhesion due to temperature, so that the electrode and the diaphragm will not be misaligned due to displacement during the transmission process.
[0053] PET has a certain degree of elastic deformation. During the subsequent hot pressing process, due to the elastic deformation, the thermal bonding between the electrode sheet and the separator is more uniform and the adhesion effect is better.
[0054] The heat bonding through the conveyor belt makes the stacking efficiency higher. The current stacking machine uses multi-station inching to complete the stacking of the cells. It adopts continuous closed-loop conveying, which greatly simplifies the stacking process. At the same time, the inching is changed to continuous conveying, which reduces electrode misalignment and effectively improves the stacking efficiency.
[0055] By using PET clamping protection, defects such as electrode burrs caused by current stacking and positioning by grippers and negative pressure electrode adsorption are reduced.
[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
