Description

Technical Field

[0001] This invention relates to the field of battery tray technology, and in particular to a multi-specification battery positioning and protection tray. Background Technology

[0002] In the manufacturing process of power batteries, formation and capacity testing are core processes that determine the battery's electrochemical performance, structural stability, and safety. The battery tray, as a key load-bearing tool in this process, directly affects the battery molding quality and production yield due to its clamping and positioning accuracy, pressure uniformity, and adaptability to operating conditions. With the diversification of power battery product systems, batteries of different specifications and with different electrochemical systems have significantly different requirements for clamping pressure and positioning methods in the formation and capacity testing process, placing higher demands on the tray's universal adaptability and protective performance.

[0003] Existing battery trays mostly employ rigid clamping structures, which are prone to localized stress concentration and uneven overall stress during battery loading. Prolonged pressure can cause battery casing deformation and internal electrode misalignment damage, directly impacting the quality and structural reliability of the finished battery. Furthermore, rigid trays lack deformation buffering capabilities. When the battery expands normally or abnormally during processing, the rigid constraints cannot adaptively yield, further increasing the risk of battery breakage and posing certain safety hazards. In addition, different battery systems, such as lithium iron phosphate and ternary lithium batteries, have different formation and capacity testing requirements for clamping pressure. Even for the same type of battery, the required clamping pressure varies at different production stages. Existing rigid trays have fixed specifications, only suitable for a single size and single pressure condition. Frequent tray changes are necessary for multi-variety co-production lines, resulting in low changeover efficiency and high tooling costs, making it difficult to meet the processing needs of current flexible, multi-batch battery production lines.

[0004] To address this, a multi-specification battery positioning and protection tray is proposed. Summary of the Invention

Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is an isometric view of the present invention; Figure 2 This is a schematic diagram of the internal structure of the present invention.

[0019] The components include: 1. Tray body; 2. Flexible adaptive clamping mechanism; 3. Inflation and exhaust manifold; 4. Inflation and exhaust nozzle; and 5. Side limiting block. Detailed Implementation

[0020] 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.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-2 This invention provides a multi-specification battery positioning and protection tray, comprising: Tray body 1; A flexible adaptive clamping mechanism 2 is provided, and a plurality of flexible adaptive clamping mechanisms 2 are installed at intervals within the tray body 1; A drive mechanism is mounted on the tray body 1 and is used to drive the flexible adaptive clamping mechanism 2 to clamp the battery.

[0023] With this configuration, the present invention drives the flexible adaptive clamping mechanism 2 to clamp the battery through the driving mechanism. The flexible adaptive clamping mechanism 2 can disperse the pressure on the battery, ensuring that the battery is always in a stable stress state during processes such as formation and capacity testing. The uniform pressure applied by the flexible adaptive clamping mechanism 2 reduces the risk of stress concentration inside the battery. When the battery expands abnormally, the flexible adaptive clamping mechanism 2 can adaptively adjust the pressure to avoid aggravating battery damage due to the rigidity of the tray, thus providing reliable safety assurance for the battery production process and effectively improving battery quality and production yield. The present invention utilizes a flexible adaptive clamping mechanism 2, which can be adapted to changes in battery type, process requirements, and production stage. The flexible adaptive clamping mechanism 2 can be precisely adjusted by a drive component to meet diverse production needs, eliminate the need for frequent tray replacements, significantly improve production efficiency, and is applicable to batteries of various specifications and shapes.

[0024] The scheme is further optimized by installing pressure monitoring components on the end face of the flexible adaptive clamping mechanism 2 near the battery. Several pressure monitoring components are electrically connected to the pressure control system, and the drive mechanism is electrically connected to the pressure control system.

[0025] Pressure sensors monitor the pressure on the battery cells in real time and feed the data back to the pressure control system. Based on preset pressure values, the pressure control system automatically identifies trays with leaks or over-inflation, ensuring that the pressure applied to the battery remains constant and uniform. During the formation and capacity testing process, the battery needs to be charged and discharged under specific pressures; the airbag restraint trays precisely maintain this pressure, preventing performance degradation due to pressure fluctuations.

[0026] The pressure control system incorporates preset pressure thresholds and automatically compares real-time monitoring data to synchronously adjust the output power of the drive mechanism, dynamically compensating for pressure deviations and ensuring that the clamping pressure applied to the battery remains constant and uniform. The system can automatically identify and promptly warn of abnormal conditions such as tray leakage and overcharging, ensuring that the battery remains in a stable preset pressure environment during the formation and capacity testing process. This prevents pressure fluctuations from causing deviations in the battery's electrochemical performance, effectively improving the consistency of the finished battery and process safety.

[0027] The scheme has been further optimized, and the drive mechanism includes: The inflation / deflation manifold 3 is installed on the tray body 1; The inflation / deflation nozzle 4 is installed on one side of the inflation / deflation manifold 3 and communicates with the inner cavity of the inflation / deflation manifold 3; The charging and venting device is fixedly connected to and connected to the charging and venting nozzle 4, and is electrically connected to the pressure control system. Among them, several flexible adaptive clamping mechanisms 2 are fixedly connected to and connected to the charging and discharging manifold 3, and the flexible adaptive clamping mechanism 2 clamps or releases the battery through charging and discharging.

[0028] The inflation / deflation manifold 3 is fixedly mounted on the pallet body 1, serving as a unified air path carrier and connecting all flexible adaptive clamping mechanisms 2. The inflation / deflation nozzle 4 is located on the side of the manifold, acting as an external air path interface for sealed connection with the inflation / deflation equipment. During operation, the high-pressure gas output from the inflation / deflation equipment flows into the inflation / deflation manifold 3 through the inflation / deflation nozzle 4, and is then evenly distributed to each group of flexible adaptive clamping mechanisms 2, synchronously driving all clamping mechanisms to perform clamping actions. During depressurization, the gas is uniformly discharged through the manifold, achieving synchronous release of each group of clamping mechanisms. Centralized manifold air supply ensures consistent air pressure and synchronized clamping actions at each workstation, effectively avoiding problems such as uneven clamping pressure and asynchronous actions in single-group clamping. The air path structure is regular, and control is centralized, facilitating unified control of batch workstations.

[0029] Further optimization of the scheme, the flexible adaptive clamping mechanism 2 includes: A fixed flexible clamping plate is fixedly installed inside the pallet body 1; A movable flexible clamping plate is slidably connected inside the tray body 1; a pressure monitoring component is installed on the end face of the movable flexible clamping plate near the battery. The pneumatic telescopic rod has one end fixedly connected and connected to the movable flexible clamping plate, and the other end fixedly installed inside the tray body 1; the inner cavity of the pneumatic telescopic rod is fixedly connected and connected to the inflation and deflation manifold 3.

[0030] A fixed flexible clamping plate is fixed inside the tray body 1, serving as a clamping and positioning reference surface. A movable flexible clamping plate is slidably assembled inside the tray body 1, arranged opposite to the fixed flexible clamping plate, with a pressure monitoring component installed on its clamping end face. One end of a pneumatic telescopic rod is fixed to the movable flexible clamping plate, and the other end is fixed to the tray body; its inner cavity is connected to the inflation / deflation manifold 3. During ventilation operations, high-pressure gas enters the pneumatic telescopic rod, pushing the rod to extend and causing the movable flexible clamping plate to slide smoothly towards the battery side, cooperating with the fixed flexible clamping plate to clamp the battery. The dual flexible clamping plate surfaces flexibly fit against the battery sidewall over a large area, evenly distributing clamping pressure and avoiding localized stress concentration. The sliding guide clamping provides precise alignment, and the pressure monitoring component allows for real-time adjustment of the clamping force, adapting to the clamping needs of batteries with different thicknesses.

[0031] The scheme is further optimized. The flexible adaptive clamping mechanism 2 includes an airbag, which is fixedly installed inside the tray body 1. An air nozzle is installed on the airbag, and the air nozzle is fixedly connected and connected to the inflation and deflation manifold 3. A pressure monitoring component is installed on the end face of the airbag near the battery.

[0032] During clamping operations, the gas output from the inflation / deflation equipment enters the airbag through the manifold. The airbag gradually expands as the gas pressure increases, conforming to and compressing the battery sidewall in a flexible surface contact manner, thus achieving flexible clamping and fixation of the battery. When the gas is released, the airbag contracts and returns to its original position, releasing the clamping state. The airbag itself possesses excellent flexible deformation capabilities, adapting to the surface of batteries of different shapes and sizes, ensuring uniform force throughout the circumference. It also adaptively buffers the expansion deformation during battery manufacturing, avoiding damage to the battery from rigid constraints. This structure is simple, provides gentle clamping, and has strong adaptability, effectively reducing the risk of battery casing deformation and internal structural damage.

[0033] To further optimize the design, side limiting blocks 5 are installed on both sides of the tray body 1. When the battery is placed in the tray station, the side limiting blocks 5 can initially limit and guide the battery in the left and right directions, guiding the battery to accurately fall into the center area of ​​the clamping station, avoiding positional deviation or skewing during manual or robotic loading. In subsequent clamping processes, the side limiting blocks can help limit the lateral displacement of the battery, preventing the battery from sliding or misaligning during clamping, ensuring that the flexible adaptive clamping mechanism 2 can evenly conform to the battery sidewall and avoid uneven force distribution and excessive local pressure caused by off-center clamping. This can effectively improve the loading positioning accuracy and clamping stability, and reduce the process defect rate caused by battery placement deviation.

[0034] The design has been further optimized by employing an air pump in the charging and degassing equipment. The air pump precisely controls the charging pressure, charging flow rate, and degassing rate, offering rapid response and high pressure control accuracy. Combined with the pressure control system, it achieves high-precision closed-loop pressure regulation. During operation, the air pump adjusts its output pressure in real time according to the instructions from the pressure control system, quickly compensating for clamping pressure deviations and stably maintaining the preset clamping pressure value. During material release, it can quickly depressurize by evacuating air, improving workstation turnover efficiency. The air pump's power source is highly adaptable, flexibly outputting corresponding pressure parameters according to different battery types and process stages, meeting the differentiated pressure process requirements of various battery systems such as lithium iron phosphate and ternary lithium, and ensuring compatibility with multiple tray sizes.

[0035] The design was further optimized by arranging several flexible adaptive clamping mechanisms 2 at equal intervals. This evenly spaced and regular arrangement ensures that the clamping structure parameters and air supply conditions at each battery station are completely consistent, guaranteeing uniform clamping pressure and position for each battery. This significantly improves the consistency of battery processing during batch production. Simultaneously, the compact structure and high space utilization of the evenly spaced arrangement facilitate unified connection and air supply to the charging / draining manifold 3. The balanced air path length and consistent air pressure loss further ensure synchronized and equal air pressure at each station, effectively improving the uniformity of battery formation and capacity testing across the entire battery pack and reducing batch defect rates.

[0036] The design has been further optimized, with the tray body 1 made of metal. Metal possesses excellent structural strength and rigidity, high load-bearing capacity, and is not easily deformed during long-term repeated clamping operations, maintaining dimensional accuracy and structural stability at the workstation for an extended service life. Simultaneously, metal's excellent thermal conductivity helps conduct heat generated during battery formation and capacity testing, evenly distributing the overall temperature of the tray and preventing localized heat buildup, thus improving process safety. The metal tray structure is wear-resistant and impact-resistant, suitable for high-frequency turnover on production lines and automated equipment handling conditions, resulting in enhanced overall reliability and durability.

[0037] The design has been further optimized by employing a flexible pressure sensor for the pressure monitoring component. This flexible pressure sensor deforms synchronously with the flexible clamping surface, closely conforming to the battery's sidewall surface. It accurately collects contact pressure data distributed in a planar pattern, exhibiting high sensitivity and a wide pressure sensing range without causing rigid scratches or pressure damage to the battery casing. It provides real-time and accurate feedback on pressure changes during clamping, offering reliable closed-loop data support for the pressure control system. This ensures accurate and timely pressure regulation, perfectly adapting to the deformation characteristics of the flexible clamping mechanism, further improving the control precision of the clamping pressure and the battery protection effect.

[0038] According to a further optimization solution, a temperature sensor is arranged on the clamping end face of the flexible adaptive clamping mechanism 2, heat dissipation flow channels are embedded in the tray body 1 corresponding to each station area, and both the temperature sensor and the regulating valve of the heat dissipation flow channels are connected to a temperature control module matched with the pressure control system. During the battery clamping operation, the temperature sensor is closely attached to the side wall of the battery, collects the surface temperature data of the battery cell in real time, dynamically monitors the heating state of the battery cell during the formation and capacity grading process, and synchronously feeds back the data to the control system. When the temperature of the battery cell exceeds the process safety threshold, the system automatically activates the circulating heat dissipation function of the heat dissipation flow channels, rapidly dissipates the heat accumulated in the tray and the battery cell through air-cooled or liquid-cooled media, and stably controls the temperature of the battery cell within the optimal process range. This structure realizes closed-loop control of both pressure and temperature parameters, which can effectively avoid performance degradation and potential safety hazards caused by local heat accumulation in the battery cell, and further improve the consistency of finished battery products and process safety.

[0039] According to a further optimization solution, an insulating limiting groove is formed at the position of the tab corresponding to each station on the top of the tray body 1, and the inner wall of the groove is made of insulating and wear-resistant material. When the battery is loaded and placed, the tabs of the battery cell can be accurately embedded into the insulating limiting groove, so as to realize independent limiting protection for the tabs and avoid the tabs from being squeezed, bent and collided and deformed during clamping and tray transfer. Meanwhile, the insulating groove can isolate the contact between the tabs and the metal tray body, fundamentally eliminating the short-circuit risk triggered by the lap joint of the tabs. This structure cooperates with the side flexible clamping mechanism to form special protection for fragile tabs while fixing the main body of the battery cell, effectively reducing the process defect rate such as tab damage and short circuit, and adapting to the protection requirements of high-precision lithium battery production.

[0040] According to a further optimization solution, an elastic supporting buffer pad is arranged at the bottom of each station of the tray body 1, and the buffer pad is made of insulating flexible material. When the battery cell is placed into the station, the elastic supporting buffer pad can bear the weight of the bottom of the battery cell, buffer the instantaneous impact of falling during loading, and avoid rigid bump damage to the bottom of the battery cell; when the battery cell expands in volume during the formation and capacity grading process, the buffer pad can adaptively compress and give way, and cooperate with the side flexible adaptive clamping mechanism 2 to form all-round flexible package protection, avoiding local stress concentration caused by rigid support at the bottom. Meanwhile, the buffer pad has insulation and heat insulation performance, which can isolate the direct contact between the battery cell and the metal tray, assist in equalizing the bottom temperature, and further improve the all-around protection effect of the battery cell.

[0041] The design has been further optimized by incorporating a quick-change mounting interface on the clamping end face of the flexible adaptive clamping mechanism 2. This interface supports a variety of replaceable clamping heads, including square flat clamping heads, curved clamping heads, and wide-face clamping heads specifically designed for soft-pack cells. During production model changes, there is no need to replace the entire tray; simply replace the corresponding clamping head via the quick-change interface to quickly adapt to the clamping requirements of different product shapes, such as square hard-shell cells, cylindrical cells, and soft-pack cells. Combined with the adjustable pressure function of the drive mechanism, it enables compatible clamping of multiple specifications and shapes of cells, significantly reducing tooling changeover costs and time, and substantially improving the tray's production line adaptability and flexible production capabilities.

[0042] The design has been further optimized by fully covering the inner wall of the pallet body 1, the contact surfaces at workstations, and the surface of the flexible clamping mechanism with an insulating and anti-static coating, and adding insulating support pads to the bottom of the pallet. After the metal pallet body undergoes insulating and anti-static treatment, the conductive path between the battery cell and the metal substrate is completely isolated, eliminating the risk of short circuits caused by the battery cell shell contacting the pallet. Simultaneously, it effectively eliminates the accumulation of static electricity generated during pallet turnover and clamping operations, preventing electrostatic discharge damage to the internal electrodes and electrochemical system of the battery cell. This structure comprehensively improves the electrical safety performance of the pallet, meeting the high standards of electrostatic protection and insulation protection required in lithium battery production, and reducing safety hazards during the production process.

[0043] Example 2 The difference between this embodiment and Embodiment 1 is that the flexible adaptive clamping mechanism 2 includes a cylinder seat, a piston rod, a pressure equalizing flexible pad, and a return spring; the cylinder seat is fixedly installed inside the tray body 1, and the inner cavity of the cylinder seat is sealed and connected to the filling and exhaust manifold 3; the piston rod is slidably assembled inside the cylinder seat, and the front end of the rod extends out of the cylinder seat and is fixedly connected to the pressure equalizing flexible pad; the pressure equalizing flexible pad has a micro-convex elastic dot matrix structure arranged on the clamping surface facing the battery; the return spring is sleeved on the outside of the piston rod, and its two ends abut against the end face of the cylinder seat and the back of the pressure equalizing flexible pad, respectively; the pressure monitoring component is attached to the clamping end face of the pressure equalizing flexible pad.

[0044] During operation, high-pressure gas is introduced into the cylinder seat cavity through the inflation / deflation manifold 3. The gas pressure pushes the piston rod forward, causing the pressure-equalizing flexible pad to smoothly adhere to the battery sidewall. The elastic dot matrix at the front end can adaptively conform to the surface morphology of the material, evenly distributing the clamping pressure to the battery sidewall and avoiding localized stress concentration. At the same time, the piston structure ensures accurate clamping stroke and stable positioning rigidity. When the pressure is released, the return spring elastically retracts, causing the piston rod and the pressure-equalizing flexible pad to return to their original positions synchronously, quickly releasing the clamp. This structure combines rigid positioning accuracy with flexible buffer protection, adapting to the clamping requirements of high-precision, high-cycle automated production lines.

[0045] Example 3 The difference between this embodiment and Embodiment 1 is that the flexible adaptive clamping mechanism 2 includes a mounting housing, a flexible elastic diaphragm, a pressure equalizing buffer filler, and a sealing ring; the mounting housing is embedded and fixed inside the tray body 1, and a sealed venting cavity is opened inside the housing, which is sealed and connected to the inflation / deflation manifold 3; an opening is opened on the side of the mounting housing facing the battery, and the flexible elastic diaphragm is pressed and sealed at the opening by the sealing ring, and pressure equalizing buffer filler is filled between the flexible elastic diaphragm and the inner wall of the venting cavity; the pressure monitoring component is attached to the outer clamping surface of the flexible elastic diaphragm.

[0046] During operation, high-pressure gas enters the venting chamber of the mounting housing through the charge / discharge manifold 3. The increased gas pressure within the chamber acts evenly on the inner side of the flexible diaphragm, pushing it to bulge gently towards the battery side. Internal pressure-equalizing buffer filler ensures the clamping surface flexibly conforms to the battery sidewall, achieving uniform pressure across the entire contact surface. After venting, the flexible diaphragm automatically retracts and resets due to its own elasticity, releasing the clamp. This structure has no sliding friction parts, excellent sealing performance, long service life, and high flexibility in the clamping surface, making it suitable for battery products with slightly irregular surfaces and thinner casings, minimizing the deformation impact of clamping on the cell casing.
