In the fields of battery production, detection, aging test and centralized charging, batch charging operation is often required for hundreds of batteries.

[0003] At present, the existing technology mainly adopts manual plugging mode to connect single batteries to the charging ports of the charging cabinet one by one. For example, Chinese invention patent CN208690981U discloses a plug-in charging cabinet, which connects the battery box loaded with batteries to the charging port by manually pushing the battery box into the slot. The degree of automation is low, and it completely depends on manual operation. The plugging time of a single battery is about 5-10 seconds, which cannot meet the demand of large batch battery charging. SUMMARY

[0005] In order to solve the above technical problems, the technical scheme adopted by the present application is as follows: a batch battery automatic charging cabinet, comprising a cabinet body; a feeding mechanism arranged in the cabinet body, used for moving a tray loaded with batteries to be charged to a feeding station; a charging mechanism comprising a plurality of charging modules arranged in an array, each charging module being provided with a plug-in port for electrical connection with the battery; a conveying mechanism comprising a moving assembly and a clamping assembly, the moving assembly being connected to the cabinet body and movable in X / Y / Z three-axis directions, and the clamping assembly being connected to the execution end of the moving assembly; a control unit in communication connection with the feeding mechanism, the charging mechanism and the conveying mechanism, used for coordinating the actions of the mechanisms; The control unit is configured to control the feeding mechanism to move the tray to the feeding station, control the moving assembly to drive the clamping assembly to move above the tray, control the clamping assembly to grasp the battery to be charged, and control the moving assembly to move the battery to the plug-in port of the charging mechanism to complete automatic plug-in charging.

[0006] The application has the beneficial effects that the batch battery automatic charging cabinet provided by the application builds a closed-loop operation system from batch feeding of the battery from the tray, automatic grabbing, multi-station parallel charging to completed discharging through the cooperative configuration of the cabinet body, the feeding mechanism, the carrying mechanism, the charging mechanism and the control unit. The feeding mechanism transfers the tray loaded with the battery to be charged as a whole to realize simultaneous feeding of multiple batteries. The moving assembly of the carrying mechanism drives the clamping assembly to continuously work in the X / Y / Z three-axis direction to distribute the batteries one by one to the charging mechanism quickly. The charging mechanism provides parallel charging capacity through the array arrangement of multiple charging modules. The control unit uniformly coordinates the actions of each mechanism to make the whole system continuously run without manual intervention. The configuration eliminates the efficiency bottleneck of manual plug-in and plug-out, enables the charging cabinet to have the capacity of automatic, continuous and large-scale charging processing of a large number of batteries, and meets the efficient charging demand in the industrialized batch production and centralized operation scene.

DETAILED DESCRIPTION

[0009] To explain the technical content, the purposes and the effects of the application in detail, the following will be explained in combination with the embodiments and the drawings.

[0010] Please refer to Figure 1 and Figure 2The application discloses a kind of batch battery automatic charging cabinet, including cabinet 1, feeding mechanism 2, charging mechanism 3, handling just and control unit;Feeding mechanism 2 is located in the cabinet 1, for the tray loaded with battery to be charged is sent to feeding station;Charging mechanism 3 includes a plurality of charging modules 31 arranged in array, each charging module 31 is equipped with the plug-in port for electrical connection with battery;Handling mechanism includes moving assembly 4 and clamping assembly 5, the moving assembly 4 is connected with the cabinet 1 and can move in X / Y / Z three-axis direction, and the clamping assembly 5 is connected to the execution end of the moving assembly 4;Control unit is connected with feeding mechanism 2, charging mechanism 3, handling mechanism, for coordinating the action of each mechanism; The control unit is configured to control the feeding mechanism 2 to move the tray to the feeding station, control the moving assembly 4 to drive the clamping assembly 5 to move above the tray, control the clamping assembly 5 to grasp the battery to be charged, and control the moving assembly 4 to move the battery to the plug-in port of the charging mechanism 3 to complete automatic plug-in charging.

[0011] The working principle of the application is briefly described as follows: After the charging cabinet is started, the control unit first sends an instruction to the feeding mechanism 2 to drive it to move the tray loaded with the battery to be charged to the feeding station in the cabinet 1. After the tray is in place, the control unit sends a motion instruction to the moving assembly 4 of the handling mechanism, and the moving assembly 4 drives the clamping assembly 5 connected to its execution end to move to a predetermined grasping position above the tray in the X / Y / Z three-axis direction. The clamping assembly 5 performs a grasping action to firmly hold a single battery to be charged in the tray.

[0012] Subsequently, the control unit controls the moving assembly 4 to move the clamping assembly 5 holding the battery from the tray station to a predetermined position of the specified charging module 31 of the charging mechanism 3. The moving assembly 4 drives the clamping assembly 5 to perform position fine adjustment, so that the battery is aligned with the plug-in port of the charging module 31, and is slowly inserted in the plug-in direction, so that the battery electrode reliably contacts the electrical contact of the plug-in port. After insertion, the charging module 31 detects the battery access signal and feeds back to the control unit, and the control unit controls the charging module 31 to start the charging program to charge the battery.

[0013] During the charging process, the control unit continuously monitors the charging state. When a single battery is fully charged, the control unit controls the handling mechanism to act again, and the clamping assembly 5 pulls out the fully charged battery from the plug-in port of the charging module 31 and moves it back to the original tray station or a discharging station. After completing a cycle, the control unit immediately dispatches the handling mechanism to return to the tray to grasp the next battery to be charged, and repeats the above process until all batteries in the tray are fully charged. The feeding mechanism 2 then moves the processed tray out and moves a new fully loaded tray in, realizing continuous batch operation.

[0014] Throughout the entire operation, the control unit coordinates and schedules all mechanisms via communication, ensuring that the feeding, gripping, transferring, connecting, charging, and unloading processes are seamlessly connected to form a complete automated closed loop, thereby enabling automatic batch charging of batteries without human intervention.

[0015] As described above, the beneficial effects of this invention are as follows: through the coordinated configuration of the cabinet 1, the loading mechanism 2, the conveying mechanism, the charging mechanism 3, and the control unit, a closed-loop operation system is constructed, encompassing batch loading of batteries from trays, automatic gripping, multi-station parallel charging, and final unloading. Specifically, the loading mechanism 2 transfers the trays containing batteries to be charged as a whole, enabling simultaneous loading of multiple batteries; the moving component 4 of the conveying mechanism drives the clamping component 5 to operate continuously in the X / Y / Z three-axis directions, rapidly distributing the batteries one by one to the charging mechanism 3; the charging mechanism 3 provides parallel charging capability through multiple charging modules 31 arranged in an array; and the control unit coordinates the actions of each mechanism, allowing the entire system to operate continuously without manual intervention. This configuration eliminates the efficiency bottleneck of manual insertion and removal of individual batteries, enabling the charging cabinet to automatically, continuously, and on a large scale charge large quantities of batteries, meeting the high-efficiency charging needs of industrial mass production and centralized operation and maintenance scenarios.

[0016] Please combine Figure 3 Furthermore, the feeding mechanism 2 includes a feeding platform 23, a feeding slide rail 22, and a feeding drive component 21. The feeding platform 23 is slidably mounted on the feeding slide rail 22 and is used to support the material tray. The feeding slide rail 22 is located inside the cabinet 1, and the feeding drive component 21 is located inside the cabinet 1 and is used to drive the feeding platform 23 to slide along the feeding slide rail 22.

[0017] As described above, the sliding transfer mechanism, consisting of the loading platform 23, the loading slide rail 22, and the loading drive component 21, enables the smooth and directional transport of the pallet along the loading slide rail 22. The guiding mechanism of the loading slide rail 22 ensures the straightness of the running trajectory of the loading platform 23 and the stability of its repeatability; the loading drive component 21 directly drives the loading platform 23, eliminating the need for manual intervention during the pallet transfer process and facilitating integration with automated logistics systems; the modular combination of the loading platform 23 and the loading slide rail 22 supports independent disassembly and maintenance, allowing for rapid repair without dismantling the main structure of the cabinet 1.

[0018] Furthermore, the loading platform 23 is provided with a fixed clamping plate 231 and a floating clamping plate 232. The fixed clamping plate 231 is used to abut against one end of the material tray, and the floating clamping plate 232 is used to abut against the other end of the material tray.

[0019] As described above, the co-clamping structure of the fixed clamping plate 231 and the floating clamping plate 232 enables the loading platform 23 to adaptively accommodate trays of different specifications. The floating clamping plate 232 elastically presses against the tray, eliminating the gap between the tray and the loading platform 23 and ensuring that the tray does not shift during transport. The double-end clamping of the fixed clamping plate 231 and the floating clamping plate 232 provides a stable and reliable gripping reference for the handling mechanism, effectively avoiding gripping failures caused by inaccurate tray positioning.

[0020] Please combine Figure 1 Furthermore, the number of the feeding mechanisms 2 is at least two.

[0021] As described above, configuring at least two feeding mechanisms 2 forms an alternating feeding mode. When one feeding mechanism 2 is in the tray-changing state, the other feeding mechanism 2 can continuously feed materials, achieving seamless connection of the feeding process. This design eliminates the equipment idle waiting caused by the material changing of a single feeding mechanism 2, and fully extends the effective working time of the charging cabinet, making it particularly suitable for industrial batch testing scenarios that require continuous and uninterrupted charging.

[0022] Please combine Figure 4 Furthermore, the moving component 4 includes: Y-axis module 41, the clamping component 5 is mounted on the Y-axis module 41, and the clamping component 5 is driven to move along the Y-axis direction through the Y-axis module 41; X-axis module 42, Y-axis module 41 is mounted on X-axis module 42, and Y-axis module 41 is driven by X-axis module 42 to move along X-axis direction; The Z-axis module 43 is fixed inside the cabinet 1, and the X-axis module 42 is installed on the Z-axis module 43. The X-axis module 42 is driven by the Z-axis module 43 to move along the Z-axis direction.

[0023] As described above, the three-axis stacked architecture of Z-axis module 43, X-axis module 42, and Y-axis module 41 significantly improves the overall structural rigidity while ensuring that the handling range covers all charging modules 31. Z-axis module 43 is fixed to the cabinet 1 to provide bottom support, X-axis module 42 is installed on Z-axis module 43 to achieve mid-level translation, and Y-axis module 41 is installed on X-axis module 42 with clamping component 5 installed on Y-axis module 41. This stacked layout optimizes the utilization of internal space in cabinet 1, and each axis module can be independently disassembled and assembled from the side or top of cabinet 1, enhancing maintenance convenience.

[0024] Furthermore, the Y-axis module 41 includes a Y-axis linear slide rail 412 and a Y-axis motor 411, and the clamping assembly 5 is slidably connected to the Y-axis linear slide rail 412 and drivenly connected to the Y-axis motor 411; the X-axis module 42 includes an X-axis linear slide rail 422 and an X-axis motor 421, and the Y-axis linear slide rail 412 is slidably connected to the X-axis linear slide rail 422 and drivenly connected to the X-axis motor 421; the Z-axis module 43 includes a Z-axis linear slide rail 432 and a Z-axis motor 431, and the X-axis linear slide rail 422 is slidably connected to the Z-axis linear slide rail 432 and drivenly connected to the Z-axis motor 431.

[0025] As described above, the sliding connection structure consisting of the Y-axis linear slide rail 412 and Y-axis motor 411, the X-axis linear slide rail 422 and X-axis motor 421, and the Z-axis linear slide rail 432 and Z-axis motor 431 significantly increases the operating speed and reduces friction loss compared to the traditional lead screw drive method. The Y-axis motor 411 directly drives the clamping assembly 5 to move along the Y-axis linear slide rail 412, the X-axis motor 421 drives the Y-axis linear slide rail 412 to move along the X-axis linear slide rail 422, and the Z-axis motor 431 drives the X-axis linear slide rail 422 to move along the Z-axis linear slide rail 432. This three-stage sliding connection decouples the axial movements, facilitating step-by-step debugging and troubleshooting.

[0026] Please combine Figure 5 Furthermore, the clamping assembly 5 includes a mounting frame 51 and a clamping cylinder 52 mounted on the mounting frame 51. The mounting frame 51 is connected to the actuating end of the moving assembly 4, and the clamping cylinder 52 has two jaws 521 that can be opened and closed relative to each other.

[0027] As described above, the clamping assembly 5 adopts a structural combination of a mounting frame 51 and a clamping cylinder 52. The clamping cylinder 52 drives the two grippers 521 to open and close relative to each other, resulting in rapid clamping response and stable output force. The two grippers 521 apply force symmetrically, keeping the battery in a balanced posture during gripping and avoiding the risk of tilting and slipping caused by unilateral force. The mounting frame 51 provides rigid support for the clamping cylinder 52, facilitating its connection to the actuator of the moving assembly 4. The standardized interface of the clamping cylinder 52 facilitates integration with pressure detection elements and electromagnetic control systems, enabling real-time monitoring of clamping force and overload protection.

[0028] Furthermore, the mounting bracket 51 is provided with a vacuum suction cup 53, which is used to pick up the battery.

[0029] As described above, a vacuum suction cup 53 is added to the mounting frame 51, forming a composite gripping mode in which the gripper 521 and the vacuum suction cup 53 work together. For soft-pack batteries with flat surfaces, the vacuum suction cup 53 can avoid the surface indentation or electrolyte leakage caused by the rigid gripper 521; for heavier batteries, the gripper 521 and the vacuum suction cup 53 work together to significantly improve gripping stability and safety; the vacuum suction cup 53 and the clamping cylinder 52 are integrated into the same mounting frame 51, expanding the compatibility of the clamping component 5 with irregularly shaped batteries, and can adapt to various battery shapes without replacing the clamping component 5 itself.

[0030] Furthermore, the vacuum suction cup 53 is detachably mounted on the mounting bracket 51.

[0031] As described above, the vacuum suction cup 53 is detachably mounted on the mounting bracket 51, allowing the clamping assembly 5 to quickly switch between a pure gripper 521 mode and a gripper 521 and vacuum suction cup 53 collaborative mode, significantly shortening the changeover and debugging cycle. When the vacuum suction cup 53 component ages or is damaged, it is not necessary to replace the entire clamping assembly 5; maintenance can be completed by simply disassembling the vacuum suction cup 53 module. The detachable structure allows for flexible replacement of the vacuum suction cup 53 with a suitable specification according to the battery size, improving gripping compatibility while reducing subsequent maintenance costs.

[0032] Please combine Figure 1 Furthermore, it also includes a CCD camera 6 that is communicatively connected to the control unit, and the CCD camera 6 is located in the cabinet 1.

[0033] As described above, a CCD camera 6, which is connected to the control unit, is installed in cabinet 1 to achieve visual servo control. The CCD camera 6 can detect and compensate for positional deviations and attitude shifts of the batteries in the tray in real time. The handling mechanism dynamically adjusts its gripping path based on visual feedback, significantly improving the gripping success rate. Furthermore, the CCD camera 6 can simultaneously perform preliminary inspection of battery appearance defects during the loading stage, identifying abnormalities such as bulging and leakage, achieving pre-screening of quality and preventing defective products from entering the charging process and causing safety hazards. The fixed connection between the CCD camera 6 and cabinet 1 ensures stable visual reference, providing a reliable image data source for the control unit.

[0034] Embodiment 1 of the present invention is a batch automatic battery charging cabinet, applicable to large-scale, continuous, and unmanned battery charging and maintenance scenarios such as battery production line aging testing, centralized charging operation of shared / leased batteries, batch pre-processing of energy storage battery prefabrication modules, periodic maintenance of emergency power supplies and backup batteries, and battery recycling, sorting, and cascade utilization. In the production process of power batteries and consumer batteries, hundreds or thousands of batteries need to undergo charge-discharge aging tests. This solution uses a feeding mechanism 2 to batch transfer battery-loaded trays. The clamping component 5 of the handling mechanism, driven by the moving component 4, cyclically grabs batteries and inserts them into the arrayed charging modules 31. The control unit centrally schedules the process to achieve 24 / 7 uninterrupted automated testing, significantly improving production line utilization and test consistency without manual intervention. In shared battery swapping services for electric bicycles, drones, and mobile robots, a large number of returned batteries need to be charged daily. The loading mechanism 2 in this solution can receive full-load trays from AGVs or conveyor lines. The control unit coordinates the handling mechanism to distribute the batteries one by one to the charging mechanism 3 for parallel charging. After charging, the batteries are automatically returned to the trays. The entire process is automated, significantly reducing battery turnaround time and site labor costs, supporting large-scale operational networks. In prefabricated energy storage system assembly scenarios, each module needs to undergo individual capacity testing and equalization charging in advance. The loading mechanism 2 in this solution is compatible with standard trays or tooling plates, sending batches of batteries to be pre-processed into the cabinet 1. The handling mechanism and charging mechanism 3 work together to complete automatic charging and SOC calibration, ensuring battery consistency before module assembly, avoiding the impact of human error on the overall performance of the energy storage system. For the periodic maintenance of backup batteries in communication base stations, data centers, and power systems, this solution supports loading backup batteries onto pallets and sending them in batches to the charging cabinet. The control unit automatically schedules the charging process according to a preset maintenance strategy, and automatically unloads the batteries after charging. This is suitable for centralized return maintenance of batteries at distributed sites or batch maintenance at regional operation and maintenance centers. In the scenario of waste battery recycling, retired batteries need to be tested for capacity and sorted. The loading mechanism 2 of this solution can accept the disassembled battery pallets, and the handling mechanism automatically grabs the batteries and inserts them into the charging module 31 for charge and discharge testing. The control unit records the charge and discharge curves and capacity data of each battery, and automatically sorts and unloads them after data binding, realizing integrated processing of testing, sorting, and charging, and improving the efficiency of waste battery evaluation. The above scenarios all share the common characteristics of large battery processing volume, high process repetition, strict requirements for charging consistency and data traceability, and high labor costs. This technical solution transforms battery charging from discrete manual operation to a continuous automated process through an automated closed-loop design, meeting the production cycle requirements of modern intelligent manufacturing and large-scale operation and maintenance.

[0035] For specific details, please refer to... Figure 1 and Figure 2The batch battery automatic charging cabinet includes a cabinet body 1, a loading mechanism 2, a charging mechanism 3, a conveying mechanism, and a control unit. The loading mechanism 2 is located inside the cabinet body 1 and is used to deliver trays loaded with batteries to be charged to the loading station. The charging mechanism 3 includes multiple charging modules 31 arranged in an array, each of which has a plug-in port for electrical connection with the battery. The conveying mechanism includes a moving component 4 and a clamping component 5. The moving component 4 is connected to the cabinet body 1 and can move in the X / Y / Z three-axis directions. The clamping component 5 is connected to the execution end of the moving component 4. The control unit is communicatively connected to the loading mechanism 2, the charging mechanism 3, and the conveying mechanism to coordinate the actions of each mechanism. The control unit is configured to: control the feeding mechanism 2 to move the tray to the feeding station, control the moving component 4 to drive the clamping component 5 to move above the tray, control the clamping component 5 to grab the battery to be charged, and control the moving component 4 to move the battery to the plug-in port of the charging mechanism 3 to complete automatic plug-in charging.

[0036] In detail, the control unit is the core coordination module for the fully automated operation of this charging cabinet. It is communicatively connected to the feeding mechanism 2, the charging mechanism 3, and the conveying mechanism, and uniformly schedules the action sequence and operating parameters of each actuator through a preset control logic program. This control unit can be implemented based on existing industrial automation control hardware such as programmable logic controllers (PLCs), industrial control computers (IPCs), embedded microcontrollers (MCUs), or motion control cards. It integrates a central processing module, an I / O interface module, a motion control module, and a communication module. It can receive feedback signals from sensors of various mechanisms (such as material tray arrival signals, battery presence detection signals, charging status signals, etc.) and output corresponding control commands to drive the relays or contactors of the feeding drive component 21, X / Y / Z axis motors 431, clamping cylinders 52, and charging module 31 to operate. This allows the entire process of feeding, gripping, transferring, connecting, charging, and unloading to be automatically executed in a predetermined cycle without manual intervention. Those skilled in the art can flexibly select commercially available standard industrial controllers and configure corresponding control programs according to the control accuracy requirements, response speed requirements, and cost budget of the actual application scenario to achieve the above-mentioned coordinated control functions.

[0037] Preferably, the batch automatic battery charging cabinet also includes a CCD camera 6 communicatively connected to the control unit, and the CCD camera 6 is mounted on the cabinet body 1. The CCD camera 6 can detect and compensate for the positional deviation and attitude deflection of the batteries in the tray in real time online. The handling mechanism dynamically adjusts the grasping path based on visual feedback, significantly improving the grasping success rate. In addition, the CCD camera 6 can simultaneously complete the initial inspection of battery appearance defects during the loading stage, identifying abnormalities such as bulging and leakage, realizing pre-quality screening, and preventing defective products from entering the charging process and causing safety hazards. The fixed connection between the CCD camera 6 and the cabinet body 1 ensures stable visual reference and provides a reliable image data source for the control unit.

[0038] For the best option, please refer to the following: Figure 1 and Figure 3 The feeding mechanism 2 includes a feeding platform 23, a feeding slide rail 22, and a feeding drive component 21. The feeding platform 23 is slidably mounted on the feeding slide rail 22 and is used to support the material tray. The feeding slide rail 22 is located inside the cabinet 1. The feeding drive component 21 is located inside the cabinet 1 and is used to drive the feeding platform 23 to slide along the feeding slide rail 22. It can be understood that the sliding transfer mechanism composed of the feeding platform 23, the feeding slide rail 22, and the feeding drive component 21 realizes the stable and directional conveying of the material tray along the feeding slide rail 22. The guiding mechanism of the feeding slide rail 22 ensures the straightness of the running trajectory and the stability of the repeatable positioning of the feeding platform 23; the feeding drive component 21 directly drives the feeding platform 23, so that the material tray transfer process does not require manual intervention and is easy to connect with the automated logistics system; the modular combination of the feeding platform 23 and the feeding slide rail 22 supports independent disassembly and maintenance, and can be quickly repaired without disassembling the main structure of the cabinet 1.

[0039] Specifically, the loading platform 23 is equipped with a fixed clamping plate 231 and a floating clamping plate 232. The fixed clamping plate 231 is used to abut against one end of the material tray, and the floating clamping plate 232 is used to abut against the other end of the material tray. The coordinated clamping structure of the fixed clamping plate 231 and the floating clamping plate 232 enables the loading platform 23 to adaptively accommodate material trays of different specifications. The floating clamping plate 232 elastically presses against the material tray, eliminating the gap between the material tray and the loading platform 23, ensuring no displacement or deviation of the material tray during transport. The double-end clamping of the fixed clamping plate 231 and the floating clamping plate 232 provides a stable and reliable gripping reference for the handling mechanism, effectively avoiding gripping failures caused by inaccurate material tray positioning.

[0040] Optionally, the number of feeding mechanisms 2 is at least two, configured to form an alternating feeding mode. When one feeding mechanism 2 is in a tray-changing state, the other feeding mechanism 2 can continuously feed, achieving seamless connection of the feeding process. This design eliminates the equipment idle waiting caused by the changing of a single feeding mechanism 2, and fully extends the effective working time of the charging cabinet, making it particularly suitable for industrial batch testing scenarios that require continuous and uninterrupted charging.

[0041] Please combine Figure 1 and Figure 4 The moving component 4 includes a Y-axis module 41, an X-axis module 42, and a Z-axis module 43. The clamping component 5 is installed on the Y-axis module 41 and is driven to move along the Y-axis direction via the Y-axis module 41. The Y-axis module 41 is installed on the X-axis module 42 and is driven to move along the X-axis direction via the X-axis module 42. The Z-axis module 43 is fixed inside the cabinet 1, and the X-axis module 42 is installed on the Z-axis module 43 and is driven to move along the Z-axis direction via the Z-axis module 43. It can be understood that the three-axis stacked architecture of the Z-axis module 43, X-axis module 42, and Y-axis module 41 significantly improves the overall structural rigidity while ensuring that the handling range covers all charging modules 31. The Z-axis module 43 is fixed to the cabinet 1 to provide bottom support. The X-axis module 42 is installed on the Z-axis module 43 to realize the translation of the middle layer. The Y-axis module 41 is installed on the X-axis module 42 and the clamping component 5 is installed on the Y-axis module 41. This stacked layout optimizes the utilization of the internal space of the cabinet 1, and each axis module can be independently disassembled and installed from the side or top of the cabinet 1, which enhances the convenience of maintenance.

[0042] Specifically, the Y-axis module 41 includes a Y-axis linear slide rail 412 and a Y-axis motor 411. The clamping component 5 is slidably connected to the Y-axis linear slide rail 412 and driven by the Y-axis motor 411. The X-axis module 42 includes an X-axis linear slide rail 422 and an X-axis motor 421. The Y-axis linear slide rail 412 is slidably connected to the X-axis linear slide rail 422 and driven by the X-axis motor 421. The Z-axis module 43 includes a Z-axis linear slide rail 432 and a Z-axis motor 431. The X-axis linear slide rail 422 is slidably connected to the Z-axis linear slide rail 432 and driven by the Z-axis motor 431.

The Y-axis motor 411 directly drives the clamping assembly 5 to move along the Y-axis linear slide rail 412. The X-axis motor 421 drives the Y-axis linear slide rail 412 to move along the X-axis linear slide rail 422. The Z-axis motor 431 drives the X-axis linear slide rail 422 to move along the Z-axis linear slide rail 432. The three-stage sliding connection decouples the axial movements from each other, which facilitates step-by-step debugging and troubleshooting.

[0043] Please combine Figure 4 and Figure 5 The clamping assembly 5 includes a mounting frame 51 and a clamping cylinder 52 mounted on the mounting frame 51. The mounting frame 51 is connected to the actuating end of the moving assembly 4. The clamping cylinder 52 has two relatively openable and closable grippers 521. It is understood that the clamping assembly 5 uses a combination of the mounting frame 51 and the clamping cylinder 52, with the clamping cylinder 52 driving the two grippers 521 to open and close relative to each other, resulting in rapid clamping response and stable output force. The symmetrical force applied by the two grippers 521 keeps the battery in a balanced posture during gripping, avoiding the risk of tilting and slipping due to unilateral force. The mounting frame 51 provides rigid support for the clamping cylinder 52, facilitating its overall connection to the actuating end of the moving assembly 4. The standardized interface of the clamping cylinder 52 facilitates integration with pressure detection elements and electromagnetic control systems, enabling real-time monitoring of clamping force and overload protection.

[0044] Specifically, the mounting frame 51 is equipped with a vacuum suction cup 53, which is used to pick up batteries. It is understood that adding a vacuum suction cup 53 to the mounting frame 51 forms a composite gripping mode where the gripper 521 and the vacuum suction cup 53 work together. For soft-pack batteries with flat surfaces, the vacuum suction cup 53 can avoid surface indentations or electrolyte leakage caused by the rigid gripper 521. For heavier batteries, the combined action of the gripper 521 and the vacuum suction cup 53 significantly improves gripping stability and safety. The vacuum suction cup 53 and the clamping cylinder 52 are integrated into the same mounting frame 51, expanding the compatibility of the clamping assembly 5 with irregularly shaped batteries, allowing it to adapt to various battery forms without replacing the clamping assembly 5 itself. Optionally, the vacuum suction cup 53 can be detachably mounted on the mounting frame 51, allowing the clamping assembly 5 to quickly switch between a pure gripper 521 mode and a gripper 521 and vacuum suction cup 53 collaborative mode, significantly shortening the changeover and debugging cycle. When the vacuum suction cup 53 component ages or is damaged, there is no need to replace the entire clamping assembly 5; maintenance can be completed by simply disassembling the vacuum suction cup 53 module. The detachable structure allows for flexible replacement of the vacuum suction cup 53 with a suitable specification according to the battery size, improving gripping compatibility while reducing subsequent maintenance costs.

[0045] Specifically, in this embodiment, there are three charging mechanisms 3, which are respectively arranged around the feeding mechanism 2. This increases the number of charging modules without increasing the overall volume of the cabinet 1. Correspondingly, the clamping assembly 5 also includes a rotary motor 54 mounted on the mounting frame 51. The output shaft of the rotary motor 54 is connected to the vacuum suction cup 53, and the clamping cylinder 52 is mounted on the vacuum suction cup 53. Through the rotation of the rotary motor 54, the clamping assembly 5 can clamp the battery to the three charging mechanisms 3 for charging, eliminating the need for a separate handling mechanism for each charging mechanism 3.

[0046] In summary, the automated batch battery charging cabinet provided by this invention constructs a closed-loop operation system for batteries, from batch loading of trays, automatic gripping, multi-station parallel charging to unloading, through the coordinated configuration of the cabinet, loading mechanism, handling mechanism, charging mechanism, and control unit. Specifically, the loading mechanism moves the trays containing batteries to be charged as a whole, enabling simultaneous loading of multiple batteries; the moving components of the handling mechanism drive the clamping components to operate continuously in the X / Y / Z axes, rapidly distributing batteries one by one to the charging mechanism; the charging mechanism provides parallel charging capability through multiple charging modules arranged in an array; and the control unit coordinates the actions of all mechanisms, allowing the entire system to operate continuously without manual intervention. This configuration eliminates the efficiency bottleneck of manual insertion and removal of individual batteries, enabling the charging cabinet to automatically, continuously, and on a large scale charge large batches of batteries, meeting the high-efficiency charging needs of industrial mass production and centralized operation and maintenance scenarios.

Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
