Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a high-capacity battery casing station. Background Technology

[0002] In the field of energy storage battery pack assembly, modular large batteries are gradually becoming the industry mainstream due to their high energy density and suitability for high-power energy storage scenarios. Precisely installing the stacked modular large batteries into a square casing (cylinder) is a core and critical process in energy storage module production. Currently, the casing installation of square modules generally adopts manual or semi-automated operation modes, which presents several technical bottlenecks: First, the positioning accuracy is poor and the stability of the casing is low. Manual positioning is prone to battery / casing misalignment and jamming. There is no dedicated guiding and limiting structure, and the casing process is prone to battery bumps and casing deformation, resulting in a high product defect rate. Second, the process is fragmented and the degree of automation is low. The battery loading, casing positioning, casing insertion, and unloading are all independent, relying on manual transfer and intervention, resulting in long production cycles and low efficiency. Third, quality control is lacking. There is no visual online detection and pressure feedback mechanism, and it is impossible to determine the casing insertion status in real time. Defects such as over-pushing and under-pushing are prone to occur, and quality cannot be closed-loop. Fourth, the tray is difficult to remove and easily damages the battery. Traditional structures do not have a lifting mechanism after casing insertion, and the tray is difficult to separate from the battery. Forcibly removing it can easily scratch the battery. Fifth, the flexibility and adaptability are weak. It is difficult to be compatible with different specifications of large-capacity batteries and casings. The equipment has poor versatility and cannot meet the needs of large-scale and flexible production.

[0003] In summary, existing square module housing technology struggles to balance precision, efficiency, and safety, suffers from high reliance on manual labor, and has uncontrollable quality. There is an urgent need to develop an automated, high-precision, and highly stable large-capacity battery housing station that can achieve a closed-loop operation of the entire process, from battery loading and housing positioning to precise housing installation, online testing, and automatic unloading, thereby solving the industry's pain points.

[0018] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0019] Please see the appendix Figure 1-10 This embodiment provides a large-capacity battery casing station, which is specifically used to feed multiple single batteries arranged in a straight line into the casing in an inverted position to form a large module battery. It solves the technical problems in the existing square module casing process, such as poor positioning accuracy, low degree of automation, lack of quality control, and difficulty in removing the tray. It realizes a fully automated closed-loop operation of battery feeding, casing positioning, accurate casing insertion, online detection, and automatic unloading.

[0020] like Figure 1 As shown, the large-capacity battery loading station mainly consists of a loading mechanism 1, a housing positioning component 2, a lifting component 3, a battery feeding mechanism 4, and a frame 5.

[0021] like Figure 4As shown, the casing insertion mechanism 1 is the core mechanism of this device for performing the battery pack casing insertion action, including the sliding tray 11 and the pusher assembly 12.

[0022] A sliding tray 11 is positioned at the initial battery position a to support the battery pack c to be installed in the casing. The battery pack c consists of multiple individual cells arranged in a straight line and placed in an inverted position on the sliding tray 11. Driven by the pusher assembly 12, the sliding tray 11 can slide linearly between the initial battery position a and the casing position b, smoothly pushing the battery pack c into the casing d.

[0023] The pusher assembly 12 is located behind the initial battery position a and includes a first drive unit 121. The first drive unit 121 is preferably a servo motor-driven lead screw module or electric cylinder, with a mounting plate 122 at its actuating end. A first connecting plate 123 is fixedly mounted on the mounting plate 122, and a sliding support plate 11 is mounted on the first connecting plate 123. The bottom surface of the sliding support plate 11 slides in contact with the sliding line assembly 332 on the support platform 33. A pusher 1231 for contacting the rear end face of the battery pack c is also mounted on the first connecting plate 123. A pressure sensor is installed between the first connecting plate 123 and the pusher 1231 to monitor the pushing force applied to the battery pack c by the pusher 1231 in real time. When the pushing force exceeds a preset safety threshold, the control system immediately stops the first drive unit 121 to prevent damage to the battery pack c due to over-pushing. A guide rail that slides with the mounting plate 122 is provided on the support platform 33 to ensure the linearity of the pusher assembly 12's movement.

[0024] like Figure 10 As shown, the housing d is also in an inverted position, with a housing terminal groove d1 and a connecting cavity d2 at its bottom. The housing terminal groove d1 corresponds to the terminal of the individual battery, and the connecting cavity d2 corresponds to the explosion relief membrane of each individual battery.

[0025] The housing positioning assembly 2 is located at the housing insertion position b and is used to precisely position and fix the housing d from multiple sides before insertion. The housing positioning assembly 2 includes a support platform 33, two sets of side baffles 21 disposed on the support platform 33, and an end face pressure plate mechanism 22.

[0026] The support platform 33 serves as the support base for the entire battery insertion station, and a guide plate 331 is installed on it at the initial battery position a. The guide plate 331 consists of two sets of vertically arranged opposite plates, and the opposite surfaces are provided with guide slopes to guide and restrict the initial position of the battery pack c, ensuring that the battery pack c remains coaxially aligned with the housing d before insertion.

[0027] like Figure 5 , 6As shown, a sliding line assembly 332 is also provided on the support platform 33. The sliding line assembly 332 is located between two sets of guide plates 331 and extends from the initial battery position a to the interior of the housing position b. The sliding line assembly 332 is preferably a roller strip, used to support the sliding support plate 11 and guide it to slide smoothly into the communicating cavity d2 of the housing d. A lifting hole 333 is provided in the bottom area of ​​the support platform 33 at the housing position b for the lifting column 3121 of the lifting assembly 3 to pass through.

[0028] Two sets of side baffles 21 are positioned opposite each other on both sides of the housing insertion position b, used to clamp and position the housing d from both sides. A second drive unit 211 is also provided on the support platform 33 to drive the two sets of side baffles 21 to move away from or towards each other. The second drive unit 211 is preferably a bidirectional lead screw module or a centering cylinder, which can synchronously drive the two sets of side baffles 21 to achieve centripetal clamping or centrifugal release, ensuring that the housing d is centered and fixed within the housing insertion position b.

[0029] like Figure 3 As shown, the end face pressure plate mechanism 22 is located at the end of the housing position b away from the battery pack c, and is used for axial positioning and pressing of the housing d from the end face direction. The end face pressure plate mechanism 22 is arranged perpendicular to the housing d inside the housing position b and is located on the side of the housing position b. The end face pressure plate mechanism 22 includes a first pneumatic component 221, a second pneumatic component 222, an end face pressure plate 223, and a locking assembly 224. The second pneumatic component 222 is located at the actuating end of the first pneumatic component 221, and the end face pressure plate 223 is located at the actuating end of the second pneumatic component 222. The end face pressure plate 223 is also provided with a pressure block 2231 on the side near the housing position b, and the pressure block 2231 is used to directly contact and press the housing d.

[0030] The first pneumatic component 221 drives the end face pressure plate 223 to move in a direction perpendicular to the sliding line group 332, causing the end face pressure plate 223 to move laterally into or out of the end face region of the housing d. The second pneumatic component 222 drives the end face pressure plate 223 to move in a direction parallel to the sliding line group 332, causing the end face pressure plate 223 to press against or release the end face of the housing d.

[0031] The locking assembly 224 is used for mechanical locking after the end face pressure plate 223 presses the housing d, preventing the end face pressure plate from loosening due to thrust during the insertion process. The locking assembly 224 includes a pin 2241 and a pin sleeve 2242 distributed on both sides of the sliding line group 332. The pin 2241 is fixedly disposed on the side of the second pneumatic component 222, and the pin sleeve 2242 is disposed on the other side of the sliding line group 332 opposite to the pin 2241. When the second pneumatic component 222 drives the end face pressure plate 223 to press the housing d, the pin 2241 moves with the second pneumatic component 222 and inserts into the pin sleeve 2242, forming a rigid lock.

[0032] A fixing plate 23 is also provided on the support platform 33. The fixing plate 23 is located at the end of the housing position b near the initial position a of the battery, and is used to fix the other end face of the housing d. The side baffle 21, the end face pressure plate mechanism 22 and the fixing plate 23 work together to achieve precise positioning of the housing d on multiple sides.

[0033] like Figure 5 As shown, the lifting assembly 3 is located at the bottom of the housing position b and is a key mechanism for solving the core pain point of difficulty in removing the sliding plate in traditional structures. When the battery pack c is pushed into the housing d, the lifting assembly 3 extends through the housing terminal groove d1 into the housing d to lift the battery pack c, so that the battery pack c is disengaged from the sliding plate 11, and the sliding plate 11 can be smoothly removed, avoiding friction between the plate and the battery pack that could cause scratches to the battery.

[0034] The lifting assembly 3 includes a lifting drive unit 31, a vision inspection unit 32, two sets of second connecting plates 34, a third pneumatic component 35, and a fourth pneumatic component 36.

[0035] Two sets of second connecting plates 34 are located at both ends of the bottom of the housing position b, with guide rails on opposite sides. The area between the two sets of second connecting plates 34, directly below the housing position b, is the working section, where lifting and inspection operations are performed.

[0036] Both the third pneumatic component 35 and the fourth pneumatic component 36 are mounted on the second connecting plate 34. A vision inspection unit 32 is located at the actuator end of the third pneumatic component 35, and a lifting drive unit 31 is located at the actuator end of the fourth pneumatic component 36. The third pneumatic component 35 and the fourth pneumatic component 36 operate alternately, driving the vision inspection unit 32 and the lifting drive unit 31 to move alternately to the working section. That is, before the battery pack is installed in the casing, the third pneumatic component 35 first moves the vision inspection unit 32 to the working section to perform visual inspection of the interior of the casing d and the installation accuracy of the battery pack c through the lifting hole 333; after the inspection is completed, the third pneumatic component 35 retracts, and the fourth pneumatic component 36 moves the lifting drive unit 31 to the working section for lifting operations.

[0037] The lifting drive unit 31 includes a lifting base plate 311, a lifting movable plate 312, and multiple liftable lifting columns 3121. The lifting base plate 311 and the lifting movable plate 312 are arranged parallel to each other vertically. Each lifting column 3121 is fixedly installed on the upper surface of the lifting movable plate 312, and the position of each lifting column 3121 corresponds one-to-one with the housing electrode slot d1 at the bottom of the housing d. The bottom of the lifting base plate 311 is provided with a lifting pneumatic component 3111 that drives the lifting movable plate 312 to move up and down. When the lifting pneumatic component 3111 is activated, it drives the lifting movable plate 312 to rise, and each lifting column 3121 passes through the lifting hole 333 on the support platform 33 and the housing electrode slot d1 at the bottom of the housing d, extending into the interior of the housing d to lift the battery pack c.

[0038] like Figure 7 As shown, the battery loading mechanism 4 is used to pick up and transport the battery pack c that has been stacked in the previous station to the battery initial position a. The battery loading mechanism 4 includes a first multi-axis drive assembly and a battery clamp 41 disposed at its execution end.

[0039] The battery clamp 41 includes symmetrically arranged end face clamps 43 and side grippers 42. The two sets of end face clamps 43 are positioned opposite each other to clamp the battery pack c from both axial ends. The two sets of side grippers 42 are L-shaped and are used to clamp and support the battery pack c from its lower side. The end face clamps 43 and side grippers 42 work together to achieve a stable grip and transport of the battery pack c, ensuring that the battery pack c will not fall or shift during transport.

[0040] like Figure 8 As shown, frame 5 is the frame support structure of the entire casing insertion station, and a second multi-axis drive mechanism is installed inside it. A flipping unloading mechanism 51 and a casing loading mechanism 52 are respectively installed on both sides of the second multi-axis drive mechanism, which are used to load the casing d at the casing insertion position b and to transfer and unload the large-capacity battery after casing insertion.

[0041] like Figure 9 As shown, the flipping and unloading mechanism 51 includes a transport support frame 511. End face clamping components 512 are provided at both ends of the transport support frame 511 for clamping the large-capacity battery after it has been installed in its casing. Two sets of cylindrical positioning components 513 are provided between the two sets of end face clamping components 512, distributed on both sides of the middle of the large-capacity battery, for clamping and supporting the side walls of the large-capacity battery, ensuring the stability of the battery module during transport.

[0042] The end-face clamping assembly 512 also contains a pin assembly 514. After the end-face clamping assembly 512 clamps both ends of the battery, the pin assembly 514 automatically locks in place to prevent the clamping from loosening and falling off due to vibration or inertia during handling. The transport carrier 511 is also equipped with a flipping assembly 515 connected to the end-face clamping assembly 512. The flipping assembly 515 is used to flip the large-capacity battery from an inverted position to an upright position during the transfer process to facilitate the flow of subsequent processes.

[0043] In this application, there is a shell feeding mechanism 52.

[0044] The working process of this invention is as follows: Shell loading and positioning stage: The shell loading mechanism 52 transports the shell d in an inverted position onto the support platform 33 of the shell insertion position b. The second drive unit 211 drives the two sets of side baffles 21 to move closer together, clamping the shell d from both sides. The first pneumatic component 221 drives the end face pressure plate 223 to move in front of the end face of the shell d, and the second pneumatic component 222 drives the end face pressure plate 223 to press the end face of the shell d, while the pin 2241 inserts into the pin sleeve 2242 to complete the mechanical locking. The shell d is precisely positioned and fixed from multiple sides.

[0045] Battery loading stage: The first multi-axis drive component of the battery loading mechanism 4 drives the battery clamp 41 to move above the battery pack c. The end face clamp 43 and the side gripper 42 clamp the battery pack c in an inverted position and transport it to the battery initial position a, and place it on the sliding tray 11.

[0046] Visual inspection stage: The third pneumatic component 35 actuates, moving the visual inspection unit 32 to the working part at the bottom of the housing position b. The visual inspection unit 32 performs visual inspection on the inside of the housing d, the position of the housing terminal slot d1, and the housing insertion path of the battery pack c. After confirming that everything is correct, the third pneumatic component 35 retracts.

[0047] During the insertion stage: The first drive unit 121 of the pusher assembly 12 is activated, driving the mounting plate 122 and the first connecting plate 123 to move forward along the guide rail. The pusher 1231 pushes the battery pack c, and the sliding support plate 11 slides along the sliding line group 332, smoothly pushing the battery pack c from the initial battery position a into the housing d at the insertion position b. A pressure sensor monitors the thrust in real time to ensure a smooth and safe insertion process.

[0048] Lifting and retracting stage: After the battery pack c is fully inserted into the casing, the fourth pneumatic component 36 actuates, moving the lifting drive unit 31 to the working section. The lifting pneumatic component 3111 drives the lifting movable plate 312 to rise, and each lifting column 3121 passes through the lifting hole 333 and the casing terminal slot d1 to extend into the casing d, lifting the battery pack c upwards and disengaging it from the sliding support plate 11. Subsequently, the first drive unit 121 reverses its action, and the pusher assembly 12 drives the sliding support plate 11 back to the initial battery position a. The lifting pneumatic component 3111 retracts, and the lifting columns 3121 descend and exit the casing d, completing the casing insertion operation.

[0049] Material unloading and transfer stage: The second drive unit 211 drives the side baffle 21 to release, the locking component 224 to unlock, and the end face pressure plate mechanism 22 to reset. The second multi-axis drive mechanism of the flipping unloading mechanism 51 drives the transport carrier 511 to move above the housing position b. The end face pressure component 512 clamps both ends of the large-capacity battery, the cylinder positioning component 513 clamps both sides of the middle of the battery, and the pin component 514 locks it. Then the flipping unloading mechanism 51 transports the large-capacity battery to the unloading station, and the flipping component 515 flips the battery from an inverted position to an upright position, completing the unloading.

[0050] Through the above structure and workflow, this invention realizes the fully automated operation of large-capacity battery casing insertion, which has significant advantages such as high positioning accuracy, stable and reliable casing insertion, non-destructive tray removal, online quality inspection, and compatibility with multiple product specifications. It effectively solves the pain points of traditional manual operation, such as poor positioning accuracy, low efficiency, and uncontrollable quality.
