Description

Technical Field

[0001] This invention relates to the field of bundling equipment, and in particular to a battery cell stacking and bundling device. Background Technology

[0002] Battery cell stacking and bundling equipment falls under the category of automated cell processing equipment in the battery manufacturing field. It is mainly used in the stacking and bundling process of cells during battery production. It is a key intermediate equipment that connects the early forming and processing of cells with the later assembly into battery modules. Its core function is to realize the transition of cells from a dispersed state to orderly stacking and reliable bundling, which is directly related to the efficiency of subsequent battery assembly and the stability of the overall cell structure.

[0003] Existing equipment for stacking and bundling battery cells suffers from several drawbacks. In the workpiece transfer stage, the coordination between the transfer and transport mechanisms is insufficient, often resulting in unstable initial workpiece movement and inaccurate delivery to the designated bundling area. This hinders the smooth transition of subsequent bundling processes, creating potential problems for the overall processing flow. Furthermore, the frame provides inadequate support for critical components, failing to maintain stable relative positions over extended periods. This leads to component swaying during operation, impacting operational accuracy. In terms of control and detection, the existing equipment's control modules have limited coordination capabilities across processes, failing to promptly receive signals and accurately send action commands. This results in disjointed workflows and low operational efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a battery cell stacking and bundling device to solve the technical problem of limited coordination capabilities, inability to receive signals from each module in a timely manner and accurately send action commands, resulting in discontinuous connections between multiple processes and low work efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a battery cell stacking and bundling device, including a base, a transmission mechanism and a transport mechanism, wherein the transmission mechanism and the transport mechanism are both disposed on the upper end of the base, wherein the transmission mechanism is used to receive the initial battery workpiece placed externally and smoothly transfer the workpiece to the top of the transport mechanism, providing initial positioning and transfer support for the subsequent transfer process of the workpiece; The transport mechanism undertakes the main task of transferring the workpiece. It can drive the workpiece to move along the preset path on the upper end of the base, and transport the workpiece from the feeding end of the equipment to the binding operation area below the frame. The upper end of the base is equipped with a frame, which is the core support frame of the equipment. It provides a stable mounting carrier for key components such as the detection module, frame, and calibration plate, ensuring that each component maintains a fixed relative position during operation and avoiding the impact of structural shaking on the operation accuracy. The front of the frame is equipped with a control module, which can receive signals from each detection component and send action commands to each execution component according to a preset program to achieve the orderly connection of processes such as transmission, correction, bundling, and cutting. Detection modules are connected to both sides of the top of the frame cavity, and a sensor module is set at the bottom of the detection module. The detection module and the sensor module work together: the sensor module can collect the position signal of the workpiece in real time to ensure that the workpiece accurately reaches the bottom of the frame. The detection module monitors the stacking status of the battery cells in the workpiece. If any abnormalities such as stacking skew or misalignment are detected, the information is fed back to the control module to prevent unqualified workpieces from entering the bundling process. A frame is installed at the top of the inner cavity of the machine frame, and a first electric telescopic component connects the frame to the machine frame. The first electric telescopic component can drive the frame to move up and down vertically. Once the workpiece is positioned, the first electric telescopic component extends, causing the frame to descend and fit over the outside of the battery workpiece, providing the strapping mechanism with working space close to the workpiece. After the strapping operation is completed, the first electric telescopic component retracts, causing the frame to return to its original position, making room for the subsequent transfer of workpieces. The inner cavity of the frame is equipped with an electric track module, and the output end of the electric track module is connected to the strapping mechanism. The electric track module can drive the strapping mechanism to move along a preset trajectory within the inner cavity of the frame, enabling the strapping mechanism to complete multi-directional and uniform tape strapping around the battery workpiece, ensuring tightness of the strapping. The binding mechanism includes a telescopic frame, and a tape roller is provided at the bottom of the telescopic frame. The telescopic frame can adjust the horizontal or vertical position of the tape roller according to the size of the workpiece so that the tape wrapped around the outside of the tape roller can accurately contact and adhere to the surface of the battery workpiece, providing a tape adhesion base for the binding operation. A limit frame is provided at the upper end of the telescopic frame. The limiting frame restricts the movement range of the telescopic frame to prevent it from shifting during adjustment, ensuring the accuracy of the tape roller position adjustment and avoiding tape adhesion deviation. The limiting frame is externally connected to a guide plate and a third electric telescopic component. The guide plate guides the tape as it is guided from the tape roller to the workpiece, preventing the tape from shifting, wrinkling, or breaking during movement and ensuring smooth tape adhesion to the workpiece. The output end of the third electric telescopic component is connected to a thermal cutting blade. After the binding mechanism completes binding the battery workpiece, the third electric telescopic component extends and drives the thermal cutting blade to move towards the tape connection point, cutting the tape through thermal cutting to complete the binding process. Thermal cutting also reduces tape burrs and ensures a smooth cut. The frame is externally connected to a correction plate, and a second electric telescopic component is connected between the correction plate and the frame. When the transport mechanism delivers the workpiece directly below the frame and stops, the second electric telescopic component extends, causing the correction plate to move closer to the workpiece. By contacting the side of the workpiece with the correction plate, the horizontal position of the workpiece is corrected, and the workpiece is clamped and fixed to prevent it from shifting during subsequent binding operations. After the correction is completed, the second electric telescopic component retracts, causing the correction plate to return to its original position to avoid affecting the descent of the frame.

[0006] Preferably, the second electric telescopic component, the third electric telescopic component, the first electric telescopic component, and the electric track module are electrically connected to the control module. This electrical connection allows the control module to centrally control each actuator. For example, the control module can first trigger the transport mechanism to stop, and then control the second electric telescopic component to drive the correction plate for correction. After correction, the control module sequentially controls the first electric telescopic component to drive the frame to descend, the electric track module to drive the binding mechanism to bind, and the third electric telescopic component to drive the thermal cutting blade to cut, thus avoiding chaotic operation of each component and greatly improving the automation level and process continuity of the equipment operation.

[0007] Preferably, the guide plate has a square groove on its outer side, and a guide ball is provided in the inner cavity of the square groove. The guide ball can convert the sliding friction between the tape and the inner wall of the square groove into rolling friction, which greatly reduces the frictional resistance of the tape during the unloading process, avoids damage to the tape due to friction or stretching deformation, and ensures that the tape can move smoothly along the direction of the square groove, further improving the accuracy of the tape bonding to the workpiece.

[0008] Preferably, the top of the base is provided with a track groove, and the bottom of the base is provided with a track wheel. The track wheel is slidably connected to the track groove. The sliding cooperation between the track wheel and the track groove allows the base to move flexibly along the track groove. The operator can adjust the overall installation position of the equipment according to the production line layout requirements, so that the equipment can be adapted to different feeding and discharging stations, improving the site adaptability and usage flexibility of the equipment.

[0009] Preferably, the second electric telescopic component is provided with an assembly frame on its exterior. The assembly frame is connected to the exterior of the machine frame by bolts. The assembly frame provides a stable installation support for the second electric telescopic component, preventing it from shaking due to force when the second electric telescopic component drives the correction plate to correct the workpiece, thus ensuring the stability of the correction action. At the same time, the bolt connection method facilitates the disassembly and maintenance of the assembly frame. When the second electric telescopic component malfunctions, the assembly frame can be quickly disassembled for inspection or replacement, reducing equipment maintenance costs and downtime.

[0010] Preferably, the calibration plate is connected to the output end of the second electric telescopic component via a snap-fit ​​connector. The inner cavity of the calibration plate is provided with a rubber pad. The snap-fit ​​connector connection method allows the calibration plate to be quickly disassembled and assembled. When the calibration plate is worn or needs to be adapted to battery workpieces of different sizes, the calibration plate of the corresponding specification can be easily replaced. The rubber pad in the inner cavity of the calibration plate is elastic and can buffer the squeezing force of the calibration plate when in contact with the workpiece, avoiding scratches or damage to the surface of the workpiece due to rigid contact, and protecting the appearance and structural integrity of the workpiece.

[0011] Preferably, a crossbeam is provided at the upper end of the frame. The outside of the crossbeam is connected to the output end of the first electric telescopic component by bolts. The crossbeam can evenly transmit the driving force of the first electric telescopic component to the upper end of the frame, avoiding deformation of the frame due to excessive local stress and ensuring that the frame remains horizontal during the lifting process. The bolt connection facilitates the installation and debugging between the crossbeam and the first electric telescopic component. If there is a deviation in the lifting of the frame, it can be calibrated by adjusting the position of the bolts.

[0012] Preferably, the detection module includes an image acquisition unit and a data processing unit. The image acquisition unit works in conjunction with the sensor module to acquire image information of the battery cell stacking status. The data processing unit is electrically connected to the control module. The control module integrates an alarm unit and a wireless communication unit. The alarm unit is electrically connected to the detection module. When the detection module determines that the battery cell stacking is abnormal, the alarm unit issues an audible and visual alarm. The wireless communication unit is connected to an external remote monitoring terminal. When the image acquisition unit and sensor module work together, the sensor module first initially locates the workpiece, and then the image acquisition unit accurately captures the details of the cell stacking. The combination of the two improves the comprehensiveness and accuracy of information acquisition. The data processing unit can quickly analyze the image information to determine whether there are abnormalities such as stacking misalignment or missing cells. If an abnormality is found, the alarm unit is immediately triggered to remind on-site personnel to handle the situation in a timely manner through audible and visual signals, preventing unqualified workpieces from entering the bundling process. The wireless communication unit can upload the equipment operating status to the remote terminal in real time, allowing managers to remotely monitor the equipment, realize fault early warning and production scheduling, and improve production management efficiency.

[0013] Preferably, the transport mechanism includes a conveyor belt, a drive motor, and a tension roller. The drive motor is electrically connected to the control module and is used to drive the conveyor belt. The tension roller is rotatably connected to both ends of the transport mechanism and abuts against the inner side of the conveyor belt. The outer surface of the conveyor belt is integrally formed with anti-slip protrusions. Triangular reinforcing ribs are provided between the four corners of the bottom of the frame and the upper end face of the base. One side of the triangular reinforcing rib is welded and fixed to the outer wall of the frame, and the other side is detachably connected to the base by countersunk bolts. An elastic buffer pad is pasted on the inner side wall of the triangular reinforcing rib. The drive motor can adjust the speed of the conveyor belt under the control of the control module to adapt to different production rhythms, and can accurately respond to start and stop commands to ensure that the workpiece stops at the designated position. The tension roller always contacts the inside of the conveyor belt, which can automatically compensate for the slack of the conveyor belt and prevent the conveyor belt from slipping and causing the workpiece to shift during transmission; the anti-slip protrusions can increase the friction between the workpiece and the conveyor belt and prevent the workpiece from sliding due to vibration or slight slope during transmission. The triangular reinforcing ribs are connected by welding and countersunk bolts, which not only enhances the connection strength between the frame and the base and prevents the frame from shaking, but also facilitates disassembly and maintenance; the elastic buffer pads can absorb the vibration during equipment operation, reduce the wear and tear on the connection structure between the frame and the base, and extend the service life of the equipment.

[0014] Preferably, both ends of the tape roller are rotatably connected to the bottom of the telescopic frame via adjustable brackets. The adjustable brackets have at least two adjustment holes along the height direction of the telescopic frame, and locking bolts are inserted into the adjustment holes. The multiple adjustment holes on the adjustable brackets can realize graded adjustment of the tape roller height. The operator can adjust the tape roller to a suitable height according to the thickness of the battery workpiece or the binding position requirements, and then fix the adjustable bracket with the locking bolts so that the tape can accurately fit the corresponding position of the workpiece for binding, which greatly improves the adaptability of the equipment to battery workpieces of different specifications and expands the application range of the equipment.

[0015] In summary, this application provides a battery cell stacking and bundling device, which has the following beneficial effects: This battery cell stacking and bundling equipment, in conjunction with a transmission and transport mechanism, smoothly transfers the initial workpieces and accurately delivers them to the bundling area, laying the foundation for subsequent processes. The frame stably supports key components, maintaining their relative positions and preventing swaying to ensure operational accuracy. The control module receives signals and sends instructions, enabling the orderly connection of multiple processes and improving operational efficiency. The detection and sensor module works together to accurately locate workpieces and detect their stacking status, filtering out unqualified workpieces to ensure quality. The frame, in conjunction with the first electric telescopic component, raises and lowers as needed to provide space or create passageways for bundling, adapting to process requirements. The electric track module drives the bundling mechanism to move in multiple directions, achieving uniform bundling and ensuring tightness. In the bundling mechanism, the telescopic frame adjusts the tape roller position as needed, the limit frame prevents deviation and ensures precise adhesion, the guide plate prevents tape issues, and the thermal cutting blade cuts the tape evenly. The correction plate, in conjunction with the second electric telescopic component, corrects the workpiece position and clamps it to prevent displacement. After correction, the return to its original position does not affect the frame's movement, improving overall operational accuracy and stability. Attached Figure Description

Detailed Implementation

[0018] This application provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2A battery cell stacking and bundling device includes a base 1, a transmission mechanism 11, and a transport mechanism 2. Both the transmission mechanism 11 and the transport mechanism 2 are located on the upper end of the base 1. The transmission mechanism 11 is used to receive the initial battery workpiece placed externally and smoothly transfer the workpiece to the top of the transport mechanism 2, providing initial positioning and transfer support for the subsequent transfer process of the workpiece. The transmission mechanism 11 adopts an anti-slip conveyor belt design. The surface texture of the conveyor belt can increase the friction with the workpiece, preventing the workpiece from slipping due to vibration during the transfer process. Low-resistance guide strips are provided on both sides of the conveyor belt to guide the workpiece to move in a straight line, further ensuring the positional accuracy during transfer and laying the foundation for the accurate receiving of the subsequent transport mechanism 2. The transport mechanism 2 moves the workpiece along a preset path on the upper end of the base 1, conveying the workpiece from the feeding end of the equipment to the binding operation area below the frame 3. The preset path is a straight track aligned with the bottom of the frame 3, with metal guide edges on both sides to prevent the workpiece from shifting laterally during transport. The conveyor belt speed of the transport mechanism 2 can be adjusted by the control module 31 to adapt to the transport requirements of workpieces of different sizes, avoiding workpiece shaking due to excessive speed or affecting production efficiency due to excessively slow speed. The upper end of the base 1 is equipped with a frame 3, which is the core support frame of the equipment. It provides a stable mounting carrier for key components such as the detection module 33, frame 4, and calibration plate 5, ensuring that each component maintains a fixed relative position during operation and avoiding the impact of structural shaking on the operation accuracy. The frame 3 is made of high-strength aluminum alloy, and each component mounting position is equipped with laser-engraved scale lines to facilitate position calibration during installation, further ensuring the accuracy of the relative position between components and reducing operation errors caused by installation deviations. The front of the frame 3 is equipped with a control module 31, which can receive signals from various detection components and send action commands to various execution components according to a preset program to achieve the orderly connection of processes such as transmission, correction, bundling, and cutting. The control module 31 is equipped with a 10-inch touch screen, allowing operators to view the progress of each process and the operating status of the components in real time. It can also manually modify parameters such as the number of bundling turns and the cutting temperature. It also has a built-in fault memory function, which can automatically record the fault point and fault time when the equipment malfunctions, facilitating subsequent maintenance and troubleshooting. Detection modules 33 are connected to both sides of the top of the inner cavity of the frame 3. A sensor module 32 is set at the bottom of the detection module 33. The detection module 33 and the sensor module 32 work together: the sensor module 32 can collect the position signal of the workpiece in real time to ensure that the workpiece accurately reaches the bottom of the frame 3; the sensor module 32 is an infrared displacement sensor, which will send a deceleration signal to the control module 31 in advance to make the transport mechanism 2 stop slowly and prevent the workpiece from exceeding the designated position due to inertia. The detection module 33 detects the stacking status of the battery cells in the workpiece. If any abnormalities such as stacking skew or misalignment are found, the information can be fed back to the control module 31 to prevent unqualified workpieces from entering the bundling process. The image acquisition unit of the detection module 33 can capture 15 frames per second. The data processing unit compares the acquired images with the preset standard stacking images. When the deviation exceeds 1mm, it is immediately judged as an abnormality. At the same time, the control module 31 will pause the subsequent process and trigger an alarm until the staff has finished handling it. A frame 4 is set at the top of the inner cavity of the frame 3. A first electric telescopic component 41 is connected between the frame 4 and the frame 3. The first electric telescopic component 41 can drive the frame 4 to move up and down in the vertical direction. Please see Figure 3 Once the workpiece is positioned, the first electric telescopic component 41 extends, causing the frame 4 to descend and fit over the battery workpiece, providing the binding mechanism 6 with working space close to the workpiece. After binding is completed, the first electric telescopic component 41 retracts, causing the frame 4 to return to its original position, making room for subsequent workpiece transfer. The telescopic component 41 has two extension / retraction speeds; the low-speed mode is used during descent to prevent the frame 4 from rapidly descending and impacting the workpiece, shortening the return time and improving the overall operating efficiency of the equipment. Furthermore, the telescopic component has a built-in stroke sensor that can precisely control the lifting height of the frame 4, ensuring uniform gaps when fitting the workpiece. The inner cavity of the frame 4 is equipped with an electric track module 43. The output end of the electric track module 43 is connected to the binding mechanism 6. The electric track module 43 can drive the binding mechanism 6 to move along the preset track of the inner cavity of the frame 4, so that the binding mechanism 6 can complete multi-directional and uniform tape binding around the battery workpiece, ensuring the tightness of the binding. The preset track of the electric track module 43 is a closed loop, which is adapted to the outer contour of the workpiece. The moving speed can be adjusted synchronously with the tape release speed to avoid the tape from stretching due to moving too fast or accumulating due to moving too slowly. In addition, the track module adopts a silent slide rail design, with operating noise below 60 decibels, improving the workshop working environment. Please see Figure 4 The binding mechanism 6 includes a telescopic frame 61, with a tape roller 62 at the bottom. The telescopic frame 61 can adjust the horizontal or vertical position of the tape roller 62 according to the workpiece size, so that the tape wrapped around the tape roller 62 can accurately contact and adhere to the surface of the battery workpiece, providing a basis for tape adhesion for the binding operation. The adjustment accuracy of the telescopic frame 61 is ±0.2mm, and fine adjustment in the horizontal and vertical directions can be achieved through a knob-type adjustment structure. After adjustment, the position can be fixed by locking the nut to prevent displacement during operation. The surface of the tape roller 62 is provided with an anti-slip rubber layer to prevent the tape from slipping during release and ensure stable tape output speed. A limit frame 63 is provided at the upper end of the telescopic frame 61. The limiting frame 63 restricts the movement range of the telescopic frame 61 to prevent it from shifting during adjustment, ensuring the accuracy of the tape roller 62's position adjustment and avoiding tape adhesion deviation. The limiting frame 63 is equipped with a limit switch; when the telescopic frame 61 is adjusted to its limit position, the limit switch triggers a power-off protection, stopping the telescopic frame 61's movement and preventing damage to components due to excessive extension / retraction. Simultaneously, wear-resistant pads are provided at the contact points between the limiting frame 63 and the telescopic frame 61 to reduce wear caused by long-term friction. The limiting frame 63 is externally connected to a guide plate 66 and a third electric telescopic component 64. The guide plate 66 guides the tape as it is guided from the tape roller 62 to the workpiece, preventing tape shifting, wrinkling, or breaking during movement and ensuring smooth tape adhesion to the workpiece. The guide channel width of the guide plate 66 is compatible with commonly used tape widths, and the inner wall of the channel is polished to further reduce tape movement resistance and wear. The output end of the third electric telescopic component 64 is connected to a thermal cutting blade 65. After the bundling mechanism 6 completes the bundling of the battery workpiece, the third electric telescopic component 64 extends and drives the thermal cutting blade 65 to move towards the tape joint. The tape is cut by thermal cutting to complete the bundling. Thermal cutting can reduce the burrs on the tape and ensure a smooth cut. The temperature of the thermal cutting blade 65 can be adjusted according to the tape material to avoid the tape from burning due to excessive temperature or being unable to cut due to insufficient temperature. The cutting blade is also equipped with a heat-insulating protective sleeve to prevent burns to other parts of the equipment or personnel. Please see Figure 5 The frame 3 is externally connected to a correction plate 5, and a second electric telescopic component 52 is connected between the correction plate 5 and the frame 3. When the transport mechanism 2 transports the workpiece to directly below the frame 3 and stops, the second electric telescopic component 52 extends, causing the correction plate 5 to move closer to the workpiece. By contacting the side of the workpiece with the correction plate 5, the horizontal position of the workpiece is corrected, and the workpiece is clamped and fixed to prevent it from shifting during subsequent binding operations. After the correction is completed, the second electric telescopic component 52 retracts, causing the correction plate 5 to return to its original position, thus avoiding affecting the descent of the frame 4. The contact end face of the correction plate 5 is completely in contact with the side of the workpiece, preventing local deformation of the workpiece due to stress. The clamping force of the second electric telescopic component 52 is adjustable, and an appropriate clamping force can be selected according to the hardness of the workpiece to ensure a firm fixation while preventing damage to the workpiece. The second electric telescopic component 52, the third electric telescopic component 64, the first electric telescopic component 41, and the electric track module 43 are electrically connected to the control module 31. This electrical connection allows the control module 31 to centrally control each actuator. For example, the control module 31 can first trigger the transport mechanism 2 to stop, and then control the second electric telescopic component 52 to drive the correction plate 5 for correction. After correction, it sequentially controls the first electric telescopic component 41 to drive the frame 4 to descend, the electric track module 43 to drive the binding mechanism 6 to bind, and the third electric telescopic component 64 to drive the thermal cutting blade 65 to cut, avoiding chaotic actions of each component and greatly improving the automation level and process continuity of the equipment operation. The connection between each component and the control module 31 uses shielded wires to reduce the impact of electromagnetic interference in the workshop on signal transmission. The signal transmission delay does not exceed 0.1 seconds, ensuring smooth connection of each process. The control module 31 also has an interlock function. For example, if the frame 4 has not descended to the correct position, the binding mechanism 6 cannot start; if the correction plate 5 has not returned to its original position, the transport mechanism 2 cannot transport the next workpiece, avoiding equipment failure or workpiece damage due to malfunction.

[0019] The guide plate 66 has a square groove 67 on its outer side, and a guide ball is installed in the inner cavity of the square groove 67. The guide ball can convert the sliding friction between the tape and the inner wall of the square groove 67 into rolling friction, which greatly reduces the frictional resistance of the tape during the delivery process, avoids damage to the tape due to friction or stretching deformation, and ensures that the tape can move smoothly along the direction of the square groove 67, further improving the accuracy of the tape adhering to the workpiece. The guide ball is made of wear-resistant nylon material to ensure that the tape is always in contact with the ball during the movement. The two ends of the square groove 67 are provided with arc transition sections to prevent the tape from being scratched by the edge of the square groove 67 when entering or exiting, further protecting the integrity of the tape. The top of the base 1 is equipped with a track groove, and the bottom of the base 1 is equipped with track wheels. The track wheels are slidably connected to the track groove. The sliding cooperation between the track wheels and the track groove allows the base 1 to move flexibly along the track groove. The operator can adjust the overall installation position of the equipment according to the production line layout requirements, so that the equipment can adapt to different feeding and discharging stations, improving the site adaptability and usage flexibility of the equipment. The track wheels are made of polyurethane, which is wear-resistant and shock-absorbing. The inner wall of the track groove is equipped with a grease filling port. Regularly adding grease can reduce the friction wear between the track wheels and the track groove, extend the service life, and the track wheels are equipped with a manual braking device. When the equipment is adjusted to the designated position, the brake lever can be pulled to lock the track wheels and prevent the equipment from shifting during operation. The second electric telescopic component 52 is externally equipped with an assembly frame 51, which is connected to the outside of the frame 3 by bolts. The assembly frame 51 provides a stable installation support for the second electric telescopic component 52, preventing it from shaking due to force when driving the correction plate 5 to correct the workpiece, thus ensuring the stability of the correction action. At the same time, the bolt connection method facilitates the disassembly and maintenance of the assembly frame 51. When the second electric telescopic component 52 malfunctions, the assembly frame 51 can be quickly disassembled for inspection or replacement, reducing equipment maintenance costs and downtime. The assembly frame 51 is made of welded steel plate with a load-bearing capacity of not less than 50kg. The bolts are fixed with anti-loosening nuts to prevent the bolts from loosening during long-term operation and causing the assembly frame 51 to shift. The assembly frame 51 is also equipped with a level, which can be used to calibrate the levelness of the assembly frame 51 during installation to ensure the accurate driving direction of the second electric telescopic component 52. The calibration plate 5 is connected to the output end of the second electric telescopic component 52 via a snap-fit ​​connector. The inner cavity of the calibration plate 5 is equipped with a rubber pad. The snap-fit ​​connector allows the calibration plate 5 to be quickly installed and removed. When the calibration plate 5 is worn or needs to be adapted to battery workpieces of different sizes, the calibration plate 5 of the corresponding specification can be easily replaced. The rubber pad in the inner cavity of the calibration plate 5 is elastic and can buffer the squeezing force of the calibration plate 5 when in contact with the workpiece, avoiding scratches or damage to the workpiece surface due to rigid contact, and protecting the appearance and structural integrity of the workpiece. The snap-fit ​​connector is a quick-release buckle structure, which can complete the installation and removal of the calibration plate 5 without tools. It can provide sufficient buffering effect and ensure friction during calibration, preventing the workpiece from sliding during the calibration process. A crossbeam 42 is provided at the upper end of the frame 4. The outside of the crossbeam 42 is connected to the output end of the first electric telescopic component 41 by bolts. The crossbeam 42 can evenly transmit the driving force of the first electric telescopic component 41 to the upper end of the frame 4, avoiding deformation of the frame 4 due to excessive local stress and ensuring that the frame 4 always remains horizontal during the lifting process. The bolt connection facilitates the installation and debugging between the crossbeam 42 and the first electric telescopic component 41. If there is a deviation in the lifting of the frame 4, it can be calibrated by adjusting the position of the bolts. The crossbeam 42 is made of solid stainless steel with a bending strength of not less than 200MPa. The connection point between the crossbeam 42 and the frame 4 is equipped with reinforcing ribs to further distribute the force and prevent uneven spacing between the binding mechanism 6 and the workpiece due to the tilt of the frame 4, which would affect the binding effect. The detection module 33 includes an image acquisition unit and a data processing unit. The image acquisition unit works in conjunction with the sensor module 32 to acquire image information of the battery cell stacking status. The data processing unit is electrically connected to the control module 31. The control module 31 integrates an alarm unit and a wireless communication unit. The alarm unit is electrically connected to the detection module 33. When the detection module 33 determines that the battery cell stacking is abnormal, the alarm unit issues an audible and visual alarm. The wireless communication unit connects to an external remote monitoring terminal. When the image acquisition unit and sensor module 32 work together, sensor module 32 first initially positions the workpiece, and then the image acquisition unit accurately captures the details of the cell stacking. The combination of the two improves the comprehensiveness and accuracy of information acquisition. The data processing unit can quickly analyze image information to determine whether there are abnormalities such as stacking misalignment or missing cells. If an abnormality is found, the alarm unit is immediately triggered to remind on-site personnel to handle the situation in a timely manner through sound and light signals, preventing unqualified workpieces from entering the bundling process. The wireless communication unit can upload the equipment operating status to the remote terminal in real time, allowing managers to remotely monitor the equipment, realize fault early warning and production scheduling, and improve production management efficiency. The camera of the image acquisition unit has a resolution of 2 million pixels and is equipped with a supplementary light, which can still capture clear images in low-light workshop environments. The sound level of the alarm unit can be adjusted from 60-100dB, and the light is a flashing red LED light to ensure that personnel can quickly detect the problem. The wireless communication unit supports 4G / 5G networks and uploads data at a frequency of 1 time / second. Managers can view data such as equipment output and number of faults through a mobile APP or computer to achieve remote operation and maintenance. The transport mechanism 2 includes a conveyor belt, a drive motor, and a tension roller. The drive motor is electrically connected to the control module 31 and is used to drive the conveyor belt to operate. The tension roller is rotatably connected to both ends of the transport mechanism 2 and abuts against the inner side of the conveyor belt. The outer surface of the conveyor belt is integrally formed with anti-slip protrusions. Triangular reinforcing ribs are provided between the four corners of the bottom of the frame 3 and the upper end face of the base 1. One side of the triangular reinforcing rib is welded and fixed to the outer side wall of the frame 3, and the other side is detachably connected to the base 1 by countersunk bolts. An elastic buffer pad is pasted on the inner side wall of the triangular reinforcing rib. The drive motor can adjust the speed of the conveyor belt under the control of the control module 31. The tension roller always contacts the inside of the conveyor belt, which can automatically compensate for the slack of the conveyor belt and prevent the conveyor belt from slipping and causing the workpiece to shift during transmission; the anti-slip protrusions can increase the friction between the workpiece and the conveyor belt and prevent the workpiece from sliding due to vibration or slight slope during transmission. The triangular reinforcing ribs are connected by welding and countersunk bolts, which not only enhances the connection strength between the frame 3 and the base 1 and prevents the frame 3 from shaking, but also facilitates disassembly and maintenance; the elastic buffer pad can absorb the vibration during equipment operation, reduce the wear and tear on the connection structure between the frame 3 and the base 1, and extend the service life of the equipment; the drive motor is a servo motor with a speed adjustment range of 0.5-2m / s and a start / stop response time of no more than 0.2 seconds; the tension of the tension roller can be adjusted by a spring to automatically adapt to the slack changes of the conveyor belt; the anti-slip protrusions are 2mm high and 10mm apart, increasing the coefficient of friction to 0.8; the triangular reinforcing ribs are made of Q235 steel plate with a thickness of 8mm, and the elastic buffer pad is made of silicone. Both ends of the tape roller 62 are rotatably connected to the bottom of the telescopic frame 61 via adjustable brackets. The adjustable brackets have at least two adjustment holes along the height direction of the telescopic frame 61, and locking bolts are inserted into the adjustment holes. The multiple adjustment holes on the adjustable brackets can realize graded adjustment of the height of the tape roller 62. The operator can adjust the tape roller 62 to a suitable height according to the thickness of the battery workpiece or the requirements of the binding position, and then fix the adjustable bracket with the locking bolts. This allows the tape to accurately fit the corresponding position of the workpiece for binding, greatly improving the adaptability of the equipment to battery workpieces of different specifications and expanding the scope of application of the equipment. The diameter of the adjustment holes is 8mm and the hole spacing is 10mm, which can realize graded adjustment of the height of the tape roller 62 from 0-50mm to meet the binding requirements of battery workpieces of different thicknesses. The locking bolts are hexagonal socket head cap screws, which, together with anti-loosening washers, ensure that the adjustable bracket will not loosen due to equipment vibration after being fixed. The adjustment process does not require disassembling the tape roller 62.

[0020] This solution first places the workpiece on top of the transmission mechanism 11, then places the battery workpiece on top of the transport mechanism 2 via the transmission mechanism 11. The transport mechanism 2 then transports the workpiece. When the workpiece is directly below the frame 3, the transport mechanism 2 stops working. The assembly frame 51 is activated to drive the correction plate 5 to correct and fix the workpiece. The assembly frame 51 is activated again to return to its original position. The first electric telescopic component 41 is activated to drive the frame 4 to descend and fit over the battery workpiece. The telescopic frame 61 is activated to drive the tape roller 62 to move, so that the tape on the outside of the workpiece contacts and adheres to the outside of the battery. The electric track module 43 is activated to drive the tape roller 62 to move and perform a bundling operation on the battery workpiece. After the bundling operation is completed, the third electric telescopic component 64 is activated to drive the thermal cutting blade 65 to cut the connection between the tape and the battery. The first electric telescopic component 41 is activated again to drive the frame 4 and the bundling mechanism 6 to return to their original positions. The transport mechanism 2 is then activated to transport the packaged battery.
