Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a flexible transmission and synchronous metering and calibration device and method for pouch batteries. Background Technology

[0002] As a key piece of equipment in automated production systems, the core function of conveying equipment is to achieve efficient and automated transfer of goods, products, and other items. By replacing manual handling, it reduces labor costs and improves the continuity and efficiency of the production process. It has been widely used in production lines of various industries such as electronics and new energy. In the production and processing of soft-pack batteries, conveying equipment plays an important role in the transfer of batteries between various processes. Especially after the edge cutting and folding process, the batteries need to be transferred to the subsequent testing stage through the conveying equipment to complete key operations such as weighing, barcode scanning, and data traceability. Among them, the weighing data needs to be uploaded to the MES system in real time to determine whether the battery is qualified, and the barcode scanning needs to bind the battery's identity information with the testing data to provide support for the traceability of the entire product life cycle. This places higher demands on the connection stability and functional adaptability of the conveying equipment. However, traditional transmission devices, limited by their structural design, exhibit significant shortcomings in practical applications. Firstly, the output end of traditional devices lacks a reliable connection and protection structure, making it prone to dropping due to improper connection when the pouch battery is transported to the end. This can lead to damage to the battery casing (aluminum-plastic composite film) and internal cells, resulting in economic losses. Secondly, traditional transmission devices lack specific functional adaptation designs for the characteristics of pouch batteries and subsequent testing requirements, directly necessitating manual flipping. Specifically, the pouch battery casing is made of aluminum-plastic composite film, a thin and flexible material that results in a non-perfectly flat surface. During transmission, the barcode area is prone to bending and wrinkling. If the barcode side is not directly facing the scanner, the uneven surface can cause abnormal light reflection and incomplete barcode reading. More importantly, when the battery is output to the conveyor belt after the edge-cutting process, its placement is completely random. The barcode may face the side of the conveyor belt (perpendicular to the scanner's detection direction) or the bottom (adhering to the conveyor belt surface). However, existing scanning equipment has a fixed detection angle and recognition range, effectively only reading "face-up" cases. The barcode is not compatible with randomly placed batteries, and there is a lack of mechanical structure or visual guidance mechanism to automatically adjust the battery posture. To address the issue of end-point connectivity, the announcement number is "CN216104907U". A Chinese patent discloses an automated transport device for pouch batteries. By setting a detachable storage frame and protective pad at the end of the conveyor belt, it achieves connection protection and convenient handling of batteries, reducing the risk of battery drop and damage to some extent. However, this device still does not solve the barcode recognition adaptation problem during the transport of pouch batteries: due to the lack of an automatic posture calibration module, in order to ensure successful barcode scanning, the existing technology has to rely on manual inspection of the barcode orientation of each battery on the conveyor belt, and flipping and adjusting batteries whose barcodes are not facing upwards so that the barcode side faces the barcode scanner. This manual flipping operation has become an indispensable part of the existing production process. However, manual flipping is not only inefficient and greatly affected by the skill level of the workers (skilled workers can only handle a few hundred products per hour, which is difficult to match the high-speed transport requirements of large-scale production lines), but it is also easy to cause scratches on the battery appearance and deformation of the aluminum-plastic composite film due to improper control of manual contact force. At the same time, there is a risk of missing flipping, which means that some batteries cannot be scanned and bound, thus affecting the continuity of the production process and the integrity of data traceability, and failing to achieve the function of synchronous measurement and calibration. Therefore, the existing technology needs to be improved and designed. Summary of the Invention

[0012] Optionally, both ends of the power frame are fixedly connected to support arc plates. The rear side of the support arc plates is connected to both sides of the annular rotating track.

A clamping plate is fixedly connected to the inner side of the pressure sensor, and a silicone anti-slip plate with protrusions is fixedly connected to the inner side of the clamping plate.

[0014] A flexible transmission and synchronous metering method for pouch batteries includes the following steps: Step 1: After the soft-pack battery is processed by the edge cutting and folding process, it is conveyed to the first conveyor belt of the conveyor frame. The support frame and the support base frame provide support. The operation of the first conveyor belt conveys the soft-pack battery to the weighing, scanning and calibration mechanism. The main frame supports the various components of the weighing, scanning and calibration mechanism. Step 2: When the pouch battery is transferred to the middle of the first conveyor belt, it enters the second conveyor belt above the weighing module. The weighing sensor detects the weight data of the pouch battery. The second conveyor belt continues to run. The weighing sensor transmits the weight data to the PLC controller. After receiving the data, the PLC controller compares and processes it. At the same time, it controls the barcode scanning device to start. The barcode scanner is aimed at the pouch battery to scan the barcode. The metering calibration module is started simultaneously. Step 3: If the barcode scanner successfully recognizes the barcode, the barcode recognition module transmits the barcode information to the PLC controller. The PLC controller associates the weight data with the barcode information, stores it, and uploads it to the MES system. The second conveyor belt continues to transport the soft-pack battery, working in conjunction with the first conveyor belt to complete the subsequent transport. Step 4: If the barcode scanner fails to recognize the barcode, the barcode recognition module sends a signal to the PLC controller. The PLC controller triggers the flip drive module and the lifting module to work. The lifting drive motor starts and drives the first lead screw to rotate. The front slider slides along the front rail, and the rear slider slides along the vertical rail, driving the rotating clamping module to lift and position to the corresponding height of the soft-pack battery. Step 5: The dual-axis motor of the rotary clamping module starts, driving the second lead screw to rotate. The movable block drives the clamping arm to move relative to the battery. The clamping plate contacts the soft-pack battery through the silicone anti-slip plate. The pressure sensor detects the clamping force and transmits it to the PLC controller. When the pressure reaches the preset value, the dual-axis motor stops, completing the flexible clamping. The flip drive motor drives the rotary component to rotate longitudinally, and the rotary drive motor drives the rotary component to rotate laterally, realizing full reverse adjustment. During the flipping process, the barcode scanner continues to scan. Step Six: After the barcode recognition module recognizes the barcode, the PLC controller stops the flip drive motor and the rotation drive motor. The dual-axis motor rotates in reverse to separate the clamping plate from the soft-pack battery. The lifting drive motor drives the rotating clamping module to reset. The second conveyor belt continues to transport the soft-pack battery, working in conjunction with the first conveyor belt to complete the subsequent transmission.

[0015] In summary, this application includes the following beneficial technical effects: 1. During the application of this technical solution, by setting up a weighing, barcode scanning, and calibration mechanism in conjunction with the conveyor frame, and integrating the weighing module, barcode scanning device, and synchronous calibration module, real-time weighing, barcode scanning, and synchronous data calibration can be achieved during the transmission of soft-pack batteries. At the same time, the weight data and barcode information are quickly associated, stored, and uploaded to the MES system through the PLC controller, thereby achieving the effect of accurate data matching and complete traceability. This solves the problems of untimely association between weighing and barcode scanning data, broken traceability chain, and insufficient accuracy of measurement data in the existing technology, and meets the core requirements of production inspection for data accuracy and traceability integrity, ensuring that the weight detection data of each soft-pack battery can be effectively bound to the identity information. 2. During the application of this technical solution, multiple sets of conveyor belts are set up in conjunction with stable support components to construct a continuous transmission structure. This allows for a smooth transition and transport of pouch batteries from the edge-cutting process to the subsequent inspection stage, avoiding the risk of jamming and falling during transmission. This achieves continuous transmission and battery protection, solving the problem of battery falling and being damaged due to improper connection at the end of the transmission device in the prior art, which leads to production interruption. It ensures the structural integrity of the pouch battery throughout the transmission process, adapts to the characteristics of the flexible material of the pouch battery, and provides a stable guarantee for the smooth progress of subsequent processes. 3. During the application of this technical solution, by setting up a flipping drive module, a lifting module, and a rotating clamping module to work together, combined with a flexible clamping structure and a dual longitudinal and lateral rotation adjustment method, it can automatically identify the barcode posture of the soft-pack battery during use. Through comprehensive multi-angle flipping adjustment, it ensures that the barcode face is facing the barcode scanner, and completes accurate flipping without manual intervention. At the same time, it achieves non-destructive clamping of the soft-pack battery, thus achieving the effect of high success rate of automatic flipping barcode recognition and no damage to the battery appearance. It solves the problems of low efficiency of manual flipping, easy to cause scratches and deformation of the battery appearance, and barcode unrecognizable due to missed flipping in the existing technology, and adapts to the high-efficiency requirements of large-scale production.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0019] This application discloses a flexible transmission and synchronous metering calibration device and method for pouch batteries. For example... Figure 1-10 As shown, it includes a conveyor frame 1, with a first conveyor belt 2 rotatably connected to both ends of the conveyor frame 1, and a weighing, scanning, measuring and calibration mechanism 3 fixedly installed in the middle of the outer side of the conveyor frame 1. The weighing and scanning metrology calibration mechanism 3 includes a main mounting frame 31, which is bolted to the outer middle of the conveyor frame 1. A weighing module 32 is fixedly mounted on the bottom inner side of the main mounting frame 31. A lifting module 33 is fixedly mounted on the front side of the main mounting frame 31. A tilting drive module 34 is fixedly mounted on the rear side of the main mounting frame 31. A rotating clamping module 35 is movably mounted between the inner sides of the tilting drive module 34 and the lifting module 33. The flip drive module 34 includes a vertical track 341, which is fixedly connected to the rear side of the mounting frame 31. A rear slider 342 is slidably connected inside the vertical track 341. A flip drive motor 343 is screwed onto the side of the rear slider 342 near the rotating clamping module 35. A coupling 344 is fixedly connected to the output end of the flip drive motor 343. A mounting arm 345 is fixedly mounted on the top of the vertical track 341. A barcode scanner 346 is bolted to the front end of the mounting arm 345. The barcode scanner 346 has a synchronous measurement calibration module inside. A barcode scanner 347 is fixedly connected to the bottom of the barcode scanner 346. During the application of this device, it uses a conveyor frame 1, a first conveyor belt 2, and a weighing and barcode scanning measurement calibration module. The calibration mechanism 3 allows the pouch batteries, after preliminary processing, to be conveyed to the first conveyor belt 2. The first conveyor belt 2 transports the pouch batteries to the weighing, scanning, and calibration mechanism 3. The main frame 31 of the weighing, scanning, and calibration mechanism 3 provides the mounting base for all components. The weighing module 32 at its inner bottom can detect the weight of the pouch batteries. The lifting module 33 on the front side cooperates with the flipping drive module 34 on the rear side to drive the rotating clamping module 35 to perform position adjustment and flipping actions. The vertical track 341 of the flipping drive module 34 provides sliding guidance for the rear slider 342. The flipping drive motor 343 on the rear slider 342 provides flipping power to the rotating clamping module 35 through the coupling shaft 344. The top of the vertical track 341... The barcode scanning device 346 at the front end of the mounting arm 345 can scan the barcode of the pouch battery using the barcode scanner 347 at the bottom. The synchronous measurement calibration module inside the barcode scanning device 346 can simultaneously calibrate the measurement data. When the pouch battery is transferred to the designated position, the weighing module 32 first completes the weight detection, and then the barcode scanning device 346 starts the scanning operation. If the barcode is not recognized, the lifting module 33 drives the rotating clamping module 35 to move to a suitable height. The rotating clamping module 35 clamps the pouch battery, and the flipping drive motor 343 drives the rotating clamping module 35 to flip the pouch battery until the barcode scanner 347 successfully recognizes the barcode. During this process, the synchronous measurement calibration module continuously calibrates and matches the weight data with the barcode recognition data. Through the aforementioned structural coordination, the device achieves integrated operation of soft-pack battery transmission, weighing, barcode scanning, and posture adjustment. The entire process can be completed without manual intervention, effectively improving production efficiency. The barcode scanning device 346 and the synchronous measurement calibration module ensure the accuracy of measurement data and barcode information, avoiding quality problems caused by data deviation. The collaborative work of the flip drive module 34, lifting module 33, and rotating clamping module 35 ensures the success rate of barcode recognition, solving the problems of low efficiency and error-proneness in traditional manual operation. At the same time, the integrated structural design reduces the space occupied by the equipment and adapts to the production needs of soft-pack batteries of different specifications, providing reliable support for the large-scale and automated production of soft-pack batteries.

[0020] Please refer to Figures 5-10The power assembly 351 includes a turntable 3511, which is rotatably connected to the inner side of the front slider 334 near the rear slider 342. A power frame 3512 is fixedly mounted on the rear side of the turntable 3511. A rotary drive motor 3513 is fixedly mounted on the bottom of the power frame 3512. A gear 3514 is fixedly mounted through the output end of the rotary drive motor 3513 and is connected to the rotary assembly 352. The rotary assembly 352 is fixedly connected to the rear side of the power frame 3512 and includes an annular rotary track 3521. The annular rotary track 3521 is welded to the side of the power frame 3512 near the rear slider 342. A rotary slip ring 3521 is slidably connected inside the annular rotary track 3521. 522, a connecting ring 3523 is fixedly connected to the top of the rotating slip ring 3522, and a toothed ring 3524 is fixedly connected to the outer side of the connecting ring 3523. The toothed ring 3524 and the gear 3514 are meshed together. The rear side of the annular rotating track 3521 is connected to the front end of the connecting shaft 344. Both ends of the power frame 3512 are fixedly connected to the supporting arc plates 3516. The rear side of the supporting arc plates 3516 is connected to both sides of the annular rotating track 3521. The overall cross-sectional shape of the rotating slip ring 3522, the front slider 334, and the rear slider 342 is convex. The cross-sectional shape of the internal cavity of the annular rotating track 3521, the internal cavity of the vertical track 341, and the internal cavity of the front track 331 is also convex. The clamping assembly 353 includes a guide rail 353. 1. The guide rail 3531 is screwed to the top side of the connecting ring 3523. A dual-axis motor 3532 is screwed into the middle of the guide rail 3531. A second lead screw 3533 is fixedly installed at each of the two output ends of the dual-axis motor 3532. The threads of the second lead screws 3533 at both ends of the guide rail 3531 are arranged in opposite directions. Movable blocks 3534 are slidably connected to both ends of the guide rail 3531. The movable blocks 3534 are threadedly connected to the second lead screws 3533. A clamping arm 3535 is fixedly connected to the side of the movable block 3534 near the annular rotating track 3521. The clamping arm 3535 is L-shaped. The lower end of the clamping arm 3535 moves inside the annular rotating track 3521. The clamping arm 3535 is located in the annular... A pressure sensor 3536 is fixedly connected to one end of the rotating track 3521. A clamping plate 3537 is fixedly connected to the inner side of the pressure sensor 3536. A silicone anti-slip plate 3538 with protrusions is fixedly connected to the inner side of the clamping plate 3537. During the application of this device, by setting up a power component 351, a rotating component 352, and a clamping component 353, when it is necessary to adjust the posture of the soft-pack battery, the turntable 3511 of the power component 351 can rotate inside the front slider 334. The power frame 3512 moves synchronously with the turntable 3511. After the rotation drive motor 3513 at the bottom of the power frame 3512 is started, its output end drives the gear 3514 to rotate. The gear 3514 meshes with the gear ring 3524 of the rotating component 352 for transmission.This causes the connecting ring 3523 and the rotating slip ring 3522 to slide along the internal cavity of the annular rotating track 3521. The supporting arc plate 3516 enhances the connection stability between the power frame 3512 and the annular rotating track 3521. The internal cavities of the annular rotating track 3521, the vertical track 341, and the front track 331 are all convex. The cross-sections of the rotating slip ring 3522, the front slider 334, and the rear slider 342 are also convex, ensuring the guidance and stability of each component during the sliding process. A dual-axis motor 3532 is installed on the guide rail 3531 of the clamping assembly 353. After the dual-axis motor 3532 starts, it drives the second lead screws 3533 at both ends to rotate. Since the threads of the second lead screws 3533 at both ends of the guide rail 3531 are opposite, the movable block 3534, which is threaded to the second lead screw 3533, moves in the opposite direction along the inside of the guide rail 3531. The movable block 3534 drives L The clamping arm 3535 moves synchronously, with its lower end extending into the annular rotating track 3521. A pressure sensor 3536 at its end is connected to a clamping plate 3537. A silicone anti-slip plate 3538 on the inner side of the clamping plate 3537 has protrusions. As the clamping arm 3535 moves, the silicone anti-slip plate 3538 contacts the surface of the soft-pack battery. The pressure sensor 3536 detects the clamping force in real time. When the force reaches a preset value, the dual-axis motor 3532 stops operating, completing the clamping of the soft-pack battery. Under the coordinated action of the rotary drive motor 3513 and the flip drive motor 343, the rotary component 352 drives the clamping component 353 and the soft-pack battery to perform a combined longitudinal and lateral flip until the barcode scanner 347 successfully recognizes the barcode. After the barcode is scanned, the dual-axis motor 3532 rotates in reverse, and the movable block 3534 drives the clamping arm 3535 to separate, releasing the pouch battery. This device achieves stable clamping and omnidirectional posture adjustment of the pouch battery through the precise coordination of its components. The convex-shaped structure design ensures smooth and reliable movement. The cooperation between the pressure sensor 3536 and the silicone anti-slip plate 3538 avoids damage to the pouch battery during clamping, adapting to its flexible characteristics. The meshing transmission of the gear 3514 and the gear ring 3524 ensures precise control of the flipping angle. Posture adjustment before barcode recognition can be completed without manual intervention, improving barcode recognition success rate and production efficiency, avoiding errors that may occur during manual operation, and ensuring the continuity of the production process and product quality.

[0021] Please refer to Figures 1-7The lifting module 33 includes a front rail 331, which is fixedly connected to the front end of the mounting frame 31. A lifting drive motor 332 is fixedly connected to the bottom of the front rail 331. A first lead screw 333 is rotatably connected inside the front rail 331. The bottom of the first lead screw 333 is connected to the output end of the lifting drive motor 332 via a coupling. A front slider 334 is threadedly connected to the outer surface of the first lead screw 333. The front slider 334 is slidably connected inside the front rail 331. The rear side of the front slider 334 is connected to the front end of the rotating clamping module 35. The rotating clamping module 35 includes a power component 351, a rotating component 352, and a clamping component 353. The power component 351 is rotatably connected to the inner side of the front slider 334 near the rear slider 342. The rotating component 352 is rotatably disposed between the inner side of the front slider 334 and the flip drive motor 343. The clamping component 353 is fixedly installed on the top side of the rotating component 352. During the application of this device, by setting up the lifting module 33 and the rotating clamping module 35, when the barcode scanner 347 fails to recognize the barcode of the soft-pack battery, the PLC... The controller triggers the operation of relevant components. The front rail 331 of the lifting module 33 provides installation and movement space for internal components. After the lifting drive motor 332 starts, it drives the first lead screw 333 to rotate through the coupling. The threaded engagement between the first lead screw 333 and the front slider 334 converts the rotational motion into linear motion, allowing the front slider 334 to slide smoothly along the interior of the front rail 331. The front slider 334 drives the front end of the rotating clamping module 35 to adjust its height synchronously. The rotating clamping module 35 consists of a power component 351, a rotating component 352, and a clamping component 353. The power component 351 provides power support for the overall rotation. The rotating component 352 can rotate flexibly between the slider and the flip drive motor 343. The clamping component 353 is fixed to the top side of the rotating component 352 and adjusts its position with the movement of the rotating component 352. When the rotating clamping module 35 moves to the height corresponding to the soft-pack battery, the power component 351... The rotating component 352 drives the clamping component 353 to approach the pouch battery. The clamping component 353 then activates to stably clamp the pouch battery. Subsequently, under the coordinated action of the flipping drive motor 343 and the rotating drive motor 3513, the rotating component 352 drives the clamping component 353 and the pouch battery to perform a combined longitudinal and lateral flipping until the barcode scanner 347 successfully recognizes the barcode. This device achieves automated posture adjustment of the pouch battery through the precise cooperation of the lifting module 33 and the rotating clamping module 35, eliminating the need for manual flipping. This effectively improves the success rate of barcode recognition and overall production efficiency, avoids battery appearance damage and missed flipping problems that may be caused by manual flipping, and ensures the continuity of the production process. At the same time, the stable movement of each component ensures the accuracy of posture adjustment, adapts to the production needs of pouch batteries, and provides a reliable guarantee for subsequent measurement data and barcode information binding.

The barcode scanner 347 is located directly below the weighing module 32. A mounting side plate 6 is fixedly installed on one side of the top of the conveyor frame 1. A mounting shaft 7 is fixedly installed on the front end of the top of the mounting side plate 6. A PLC controller 8 is bolted to the top of the mounting shaft 7. During the application of this device, it is equipped with a conveyor frame 1, a support frame 4, a support base frame 5, a weighing module 32, and a PLC. The controller and other structures allow the pouch batteries, after being processed by edge trimming, to be conveyed to the first conveyor belt 2 during use. The support frame 4 and the support base frame 5 provide a stable foundation for the entire device. The first conveyor belt 2 transports the pouch batteries to the designated position. When the pouch batteries reach the middle of the first conveyor belt 2, they enter the second conveyor belt 324 of the weighing module 32. The fixed base 321 of the weighing module 32 provides mounting support for the weighing sensor 322, which detects the weight data of the pouch batteries in real time. The support frame 323 supports the second conveyor belt 324, which continues to operate, ensuring the pouch batteries move smoothly and continuously during the weighing process. The weighing sensor 322 transmits the collected weight data to the PLC controller. The mounting side plate 6 and the mounting shaft 7 provide stable mounting conditions for the PLC controller, ensuring that the PLC controller can properly receive and process data. The controller pre-stores a preset weight standard range, receives weight data, performs comparison processing, and simultaneously controls the barcode scanning device 346 to start. The barcode scanner 347 is positioned directly below the weighing module 32 and scans the barcodes of the pouch batteries on the second conveyor belt 324. The synchronous measurement calibration module inside the barcode scanning device 346 works synchronously. If the barcode scanner 347 successfully recognizes the barcode, the PLC controller associates and stores the weight data with the barcode information and uploads it to the MES system to complete the binding of measurement and traceability data. Subsequently, the second conveyor belt 324 cooperates with the first conveyor belt 2 to continue transporting the pouch batteries to the subsequent processes.If the barcode scanner 347 fails to recognize the barcode, the PLC controller triggers the flip drive module 34 and the lifting module 33 to operate. The coupling 344 drives the rotary clamping module 35 to move to the corresponding height of the pouch battery. After the rotary clamping module 35 flexibly clamps the pouch battery, the flip drive motor 343 and the rotary drive motor 3513 drive the rotating component 352 to rotate longitudinally and laterally, respectively, to achieve a complete reverse adjustment until the barcode scanner 347 successfully recognizes the barcode. Afterward, the rotary clamping module 35 releases the pouch battery and resets, and the second conveyor belt 324 continues to transport the pouch battery. This device achieves this through the coordinated operation of its various structures. The system automates the entire process of soft-pack battery transfer, weighing, barcode scanning, and attitude adjustment, eliminating the need for manual intervention. This significantly improves production efficiency, avoids errors that may occur during manual operation, and ensures traceability integrity through real-time correlation between weighing data and barcode information. The synchronous calibration module guarantees data accuracy, meeting the precision requirements of production testing. The flexible clamping design of the 35mm rotating clamping module is adapted to the characteristics of soft-pack batteries, preventing potential damage during clamping. Overall, the system ensures production continuity and product quality, adapting to the needs of large-scale production.

[0023] A flexible transmission and synchronous metering method for pouch batteries includes the following steps: Step 1: After the soft-pack battery is processed by the edge cutting and folding process, it is conveyed to the first conveyor belt 2 of the conveyor frame 1. The support frame 4 and the support base frame 5 provide support. The first conveyor belt 2 operates to convey the soft-pack battery to the weighing, scanning and measuring calibration mechanism 3. The main frame 31 carries the various components of the weighing, scanning and measuring calibration mechanism 3. Step 2: When the pouch battery is transferred to the middle of the first conveyor belt 2, it enters the second conveyor belt 324 above the weighing module 32. The weighing sensor 322 detects the weight data of the pouch battery. The second conveyor belt 324 continues to run. The weighing sensor 322 transmits the weight data to the PLC controller. After receiving the data, the PLC controller compares and processes it, and at the same time controls the barcode scanning device 346 to start. The barcode scanner 347 is aimed at the pouch battery to scan the barcode, and the measurement calibration module is started simultaneously. Step 3: If the barcode scanner 347 successfully recognizes the barcode, the barcode recognition module transmits the barcode information to the PLC controller. The PLC controller associates the weight data with the barcode information, stores it, and uploads it to the MES system. The second conveyor belt 324 continues to transport the soft-pack battery, working in conjunction with the first conveyor belt 2 to complete the subsequent transmission. Step 4: If the barcode scanner 347 fails to recognize the barcode, the barcode recognition module sends a signal to the PLC controller. The PLC controller triggers the flip drive module 34 and the lifting module 33 to work. The lifting drive motor 332 starts and drives the first lead screw 333 to rotate. The front slider 334 slides along the front rail 331, and the rear slider 342 slides along the vertical rail 341, driving the rotating clamping module 35 to lift and position to the corresponding height of the soft-pack battery. Step 5: The dual-axis motor 3532 of the rotary clamping module 35 starts, driving the second lead screw 3533 to rotate. The movable block 3534 drives the clamping arm 3535 to move relative to it. The clamping plate 3537 contacts the soft-pack battery through the silicone anti-slip plate 3538. The pressure sensor 3536 detects the clamping force and transmits it to the PLC controller. When the pressure reaches the preset value, the dual-axis motor 3532 stops, completing the flexible clamping. The flip drive motor 343 drives the rotating component 352 to rotate longitudinally, and the rotary drive motor 3513 drives the rotating component 352 to rotate laterally, realizing full reverse adjustment. During the flipping process, the barcode scanner 347 continuously scans. Step Six: After the barcode recognition module recognizes the barcode, the PLC controller stops the flip drive motor 343 and the rotary drive motor 3513. The dual-axis motor 3532 rotates in reverse to separate the clamping plate 3537 from the soft-pack battery. The lifting drive motor 332 drives the rotary clamping module 35 to reset. The second conveyor belt 324 continues to transport the soft-pack battery, cooperating with the first conveyor belt 2 to complete the subsequent transmission.

[0024] The implementation principle of the flexible transmission and synchronous measurement calibration device and method for soft-pack batteries in this application embodiment is as follows: During application, after the soft-pack battery undergoes a trimming and folding process, it is conveyed to the first conveyor belt 2 of the conveyor frame 1. The support frame 4 and the support base frame 5 provide stable support for this device. The operation of the first conveyor belt 2 transports the soft-pack battery to the weighing and scanning measurement calibration mechanism 3. The mounting frame 31 serves as the mounting carrier for each component of the weighing and scanning measurement calibration mechanism 3, ensuring stable assembly of each structure. When the soft-pack battery is transported to the middle position of the first conveyor belt 2, it enters the second conveyor belt 324 above the weighing module 32. The fixed seat 321 of the weighing module 32 provides fixed support. The weighing sensor 322 detects the weight data of the soft-pack battery in real time. The support frame 323 provides the mounting base for the second conveyor belt 324. The second conveyor belt 324 continues to operate, ensuring continuous and stable transport of the soft-pack battery during the weighing process. The weighing sensor 322 transmits the collected weight data to the PLC controller. The mounting side plate 6 and the mounting shaft 7 are the PLC. The controller provides a stable installation position to ensure its normal operation. The PLC controller pre-stores the preset weight standard range, receives weight data and performs comparison processing, and at the same time controls the scanning device 346 to start. The mounting arm 345 is fixed to the top of the vertical rail 341, and the barcode recognition module inside the scanning device 346 installed at its front end starts. The barcode scanner 347 at the bottom is aligned with the soft-pack battery on the second conveyor belt 324 to scan the barcode. The synchronous measurement and calibration module inside the scanning device 346 starts working synchronously. If the barcode scanner 347 successfully recognizes the barcode, the barcode recognition module transmits the barcode information to the PLC controller. The PLC controller associates and stores the weight data with the barcode information and uploads it to the MES system to complete the binding of measurement and traceability data. Subsequently, the second conveyor belt 324 continues to transport the pouch battery, working in conjunction with the first conveyor belt 2 to complete the subsequent transmission operation. Through the connection design between the first conveyor belt 2 and the second conveyor belt 324, this device achieves a smooth transition of the pouch battery during the transmission process, avoiding the problem of battery falling and being damaged due to improper end connection in traditional transmission devices. At the same time, the real-time association between the weighing data and the barcode information solves the problems of untimely data association and incomplete traceability in traditional methods. The synchronous measurement calibration module calibrates the data to ensure data accuracy and meet the precision requirements of production testing. If the barcode scanner 347 fails to recognize the barcode, the barcode recognition module sends a signal to the PLC controller. The PLC controller triggers the flip drive module 34 and the lifting module 33 to operate. The lifting drive motor 332 in the lifting module 33 starts, and its output drives the first lead screw 333 to rotate inside the front rail 331 via a coupling. The first lead screw 333 is threadedly engaged with the front slider 334, causing the front slider 334 to slide along the internal cavity of the front rail 331. The front slider 334 drives the front end of the rotary clamping module 35 to adjust its height. In the flip drive module 34, the rear slider 342 slides along the internal cavity of the vertical track 341, working with the front slider 334 to achieve the overall lifting and positioning of the rotary clamping module 35 until the rotary clamping module 35 moves to the height position corresponding to the soft-pack battery. The vertical track 341 and the front rail 331 are aligned. The internal cavity design in the shape of the Chinese character, as well as the convex cross-section design of the rear slider 342 and the front slider 334, ensures the stability and guidance of the sliding process. When the clamping component 353 moves to the outside of the battery on the second conveyor belt 324, the clamping component 353 of the rotating clamping module 35 starts to work, and the dual-axis motor 3532 starts. Its two output ends drive the second lead screw 3533 to rotate inside the guide rail 3531. Since the threads of the second lead screw 3533 at both ends inside the guide rail 3531 turn in opposite directions, the two movable blocks 3534 threaded to the second lead screw 3533 move in opposite directions along the inside of the guide rail 3531. The movable blocks 3534 drive the clamping arm 3535 to move synchronously, and the clamping arm 3535 is in an L-shape. The device is configured such that its lower end extends into the interior of the annular rotating track 3521. As the movable block 3534 moves, the clamping plate 3537 on the inner side of the clamping arm 3535 gradually approaches the soft-pack battery. The silicone anti-slip plate 3538 on the inner side of the clamping plate 3537 contacts the surface of the soft-pack battery. The pressure sensor 3536 detects the clamping force in real time and transmits the data to the PLC controller. When the pressure reaches the preset value, the PLC controller controls the dual-axis motor 3532 to stop running, thus completing the flexible clamping of the soft-pack battery. The design of the silicone anti-slip plate 3538 in conjunction with the pressure sensor 3536 can avoid damage to the soft-pack battery caused by excessive clamping force and is adapted to the flexible characteristics of the soft-pack battery. Subsequently, the tilting drive motor 343 starts, and its output end drives the rotating component 352 to rotate longitudinally via the coupling shaft 344. The coupling shaft 344 connects the tilting drive motor 343 and the annular rotating track 3521, providing power for the longitudinal rotation. At the same time, the rotating drive motor 3513 starts, and its output end drives the gear 3514 to rotate. The gear 3514 meshes with the gear ring 3524, which is fixed to the outside of the connecting ring 3523. The connecting ring 3523 is fixedly connected to the rotating slip ring 3522, which slides along the internal cavity of the annular rotating track 3521, driving the rotating component 352 to rotate laterally, supporting the arc plate 351. 6. The connection stability between the power frame 3512 and the annular rotating track 3521 is enhanced to ensure that the structure does not deform during longitudinal and transverse rotation. The meshing transmission between the gear ring 3524 and the gear 3514 ensures precise control of the transverse rotation angle. The flip drive motor 343 and the rotation drive motor 3513 work together to achieve a complete reverse adjustment of the rotating component 352 and the clamping component 353 through longitudinal and transverse rotation. The rotating component 352 drives the clamping component 353 and the soft-pack battery to perform synchronous longitudinal and transverse compound flipping. During the flipping process, the barcode scanner 347 continuously scans the barcode until the barcode recognition module recognizes the barcode. The PLC controller then controls the flip drive motor 343 and the rotation drive motor 3513 to stop operating. Subsequently, the PLC... The controller controls the dual-axis motor 3532 to rotate in the reverse direction, driving the second lead screw 3533 to rotate in the reverse direction. The movable block 3534 drives the clamping arm 3535 to move in the opposite direction, and the clamping plate 3537 separates from the soft-pack battery, completing the release action. The lifting drive motor 332 drives the first lead screw 333 to rotate in the reverse direction, and the front slider 334 drives the rotary clamping module 35 to reset. The second conveyor belt 324 continues to transport the soft-pack battery, cooperating with the first conveyor belt 2 to complete the subsequent transmission operation. This device, through the cooperation of the automated flip drive module 34, lifting module 33 and rotary clamping module 35, utilizes the synergistic effect of the longitudinal rotation of the flip drive motor 343 and the lateral rotation of the rotary drive motor 3513 to realize the soft-pack battery... The fully automatic adjustment of the battery posture, without human intervention, completely replaces the traditional manual flipping operation, solving the problems of low efficiency, easy scratches or deformation of the battery appearance, and missed flipping. It greatly improves processing efficiency, can adapt to the high-speed transmission requirements of large-scale production lines, avoids production process interruptions caused by manual operation, and ensures production continuity. At the same time, the full reverse adjustment ensures the success rate of barcode recognition, avoids the problem of barcode binding failure caused by missed flipping, and enables the weight detection data of each soft-pack battery to correspond to the identity information, ensuring the integrity of product life cycle traceability, meeting the needs of production management and quality control, and improving the automation level of soft-pack battery production and reducing labor costs.

A flexible transmission and synchronous metering method for pouch batteries, employing the flexible transmission and synchronous metering calibration device for pouch batteries as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: After the soft-pack battery is processed by the edge cutting and folding process, it is transported to the first conveyor belt (2) of the conveyor frame (1). The support frame (4) and the support base frame (5) provide support. The first conveyor belt (2) transports the soft-pack battery to the weighing, scanning and calibration mechanism (3). The main frame (31) carries the various components of the weighing, scanning and calibration mechanism (3). Step 2: When the soft-pack battery is transferred to the middle of the first conveyor belt (2), it enters the second conveyor belt (324) of the weighing module (32). The weighing sensor (322) detects the weight data of the soft-pack battery. The second conveyor belt (324) continues to run. The weighing sensor (322) transmits the weight data to the PLC controller. After receiving the data, the PLC controller compares and processes it. At the same time, it controls the barcode scanning device (346) to start. The barcode scanner (347) is aimed at the soft-pack battery to scan the barcode. The synchronous measurement calibration module is started. Step 3: If the barcode scanner (347) successfully recognizes the barcode, the barcode recognition module transmits the barcode information to the PLC controller. The PLC controller associates the weight data with the barcode information, stores it, and uploads it to the MES system. The second conveyor belt (324) continues to transport the soft-pack battery, cooperating with the first conveyor belt (2) to complete the subsequent transmission. Step 4: If the barcode scanner (347) fails to recognize the barcode, the barcode recognition module sends a signal to the PLC controller. The PLC controller triggers the flip drive module (34) and the lifting module (33) to work. The lifting drive motor (332) starts and drives the first lead screw (333) to rotate. The front slider (334) slides along the front rail (331), and the rear slider (342) slides along the vertical rail (341), driving the rotating clamping module (35) to lift and position to the corresponding height of the soft-pack battery. Step 5: The dual-axis motor (3532) of the rotary clamping module (35) starts and drives the second lead screw (3533) to rotate. The movable block (3534) drives the clamping arm (3535) to move relative to each other. The clamping plate (3537) contacts the soft-pack battery through the silicone anti-slip plate (3538). The pressure sensor (3536) detects the clamping force and transmits it to the PLC controller. When the pressure reaches the preset value, the dual-axis motor (3532) stops, completing the flexible clamping. The flip drive motor (343) drives the rotating component (352) to rotate longitudinally, and the rotary drive motor (3513) drives the rotating component (352) to rotate laterally, realizing full reverse adjustment. During the flipping process, the barcode scanner (347) continuously scans. Step 6: After the barcode recognition module recognizes the barcode, the PLC controller controls the flip drive motor (343) and the rotation drive motor (3513) to stop. The dual-axis motor (3532) rotates in reverse to separate the clamping plate (3537) from the soft-pack battery. The lifting drive motor (332) drives the rotating clamping module (35) to reset. The second conveyor belt (324) continues to transport the soft-pack battery, cooperating with the first conveyor belt (2) to complete the subsequent transmission.
