Description

Technical Field

[0001] This invention relates to the technical field of battery tab shaping and inspection, and further to the field of new energy vehicle manufacturing, particularly to an automated production line for battery tab shaping and inspection. Background Technology

[0002] In the field of battery manufacturing, the shaping and inspection of the tabs are key process steps to ensure the reliability and safety of battery performance. In existing technologies, the processing of tabs usually involves multiple independent steps, such as initial bending of the tabs, hot pressing shaping, cold pressing shaping, scraping, leveling, pressing, and insulation withstand voltage testing. These steps are mostly completed by decentralized specialized equipment or independent workstations. The flow and positioning of batteries are achieved between the equipment through conveyor belts or manual operation, forming a segmented production mode.

[0003] With the rapid development of the new energy vehicle industry, the performance, safety, and consistency requirements for power batteries, as core components of new energy vehicles, are becoming increasingly stringent. The shaping and testing of battery tabs directly affect the reliability and lifespan of the battery. However, most existing technologies are designed for consumer electronics batteries, and their processing efficiency, precision, and automation levels are insufficient to meet the large-scale, high-rate-of-use, and highly consistent production demands of new energy vehicle batteries. Therefore, developing a highly efficient and automated shaping and testing production line specifically designed for new energy vehicle battery tabs is of great significance for improving the overall manufacturing quality and production efficiency of new energy vehicles.

[0004] However, existing technologies, due to their fragmented processes and low equipment integration, require multiple clamping and transfers during battery production. This not only reduces overall production efficiency but also introduces errors due to repeated positioning, affecting the accuracy and consistency of tab shaping. Furthermore, a single pressing method cannot simultaneously address the shaping effect and anti-springback requirements of the tab material, easily leading to weak pressing or unstable shapes. In addition, for insulation withstand voltage testing at the battery seal, traditional probes are prone to poor contact due to their inability to effectively penetrate the sealant layer, resulting in inaccurate test data or the risk of missed detections. In the secondary tab shaping stage, the separation of the scraping and leveling processes not only increases the equipment footprint but also extends the processing cycle and reduces shaping consistency due to workstation transfers. These factors collectively restrict the automation level of the battery tab processing flow and the stability of product quality.

[0005] Therefore, the inventors urgently need an automated production line for shaping and testing battery tabs to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this invention provides an automated shaping and testing production line for battery tabs, aiming to solve the problems of low production efficiency, poor consistency of shaping accuracy, and insufficient testing reliability caused by the dispersed shaping and testing processes and low equipment integration in the existing technology.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: an automated shaping and inspection production line for battery tabs, comprising a feeding shaping and inspection preparation device, a primary battery tab shaping device, and a secondary battery tab shaping device arranged in sequence. The feeding shaping and inspection preparation device includes a synchronous direct-drive transfer mechanism and a battery input conveyor belt, a sealing edge shaping mechanism, an internal resistance voltage testing mechanism, and a sealing depth testing mechanism, respectively arranged in sequence on one side of the output end of the synchronous direct-drive transfer mechanism. The primary battery tab shaping device includes several parallel hot and cold pressing conveyors. The system includes a hot and cold pressing shaping mechanism located at the end of each of the hot and cold pressing conveying mechanisms, and a hot and cold pressing input transfer mechanism, a glue application mechanism, a secondary shaping transfer mechanism, and a battery pressing and driving shaping mechanism arranged sequentially from the start to the end along the conveying direction of the hot and cold pressing conveying mechanisms, all mounted above the hot and cold pressing conveying mechanisms. The hot and cold pressing input transfer mechanism is located corresponding to the output end of the sealing depth detection mechanism, and the secondary shaping transfer mechanism spans all the hot and cold pressing conveying mechanisms and is located corresponding to the input mechanism of the battery tab secondary shaping device.

[0008] Based on the above, the advantages of an automated battery tab shaping and testing production line are that it solves the problems of low production efficiency, poor consistency of shaping accuracy, and insufficient testing reliability caused by the dispersed battery tab shaping and testing processes and low equipment integration in the existing technology; mainly reflected in:

[0009] 1. This invention integrates the feeding, inspection, primary shaping and secondary shaping processes of battery tabs onto a continuous production line by sequentially arranging a feeding, shaping and inspection preparation device, a primary shaping device for battery tabs, and a secondary shaping device for battery tabs. This achieves fully automated continuous operation of battery tabs from input to output, avoiding multiple transfers and repositioning of batteries between multiple independent devices, thereby significantly improving production efficiency and reducing the problem of inconsistent shaping accuracy caused by positioning errors.

This forms a highly integrated parallel operation mode and greatly improves the battery processing capacity per unit time.

[0012] 4. This invention achieves seamless connection and precise transfer of the battery from material input detection to primary shaping and then from primary shaping to secondary shaping by setting the cold and hot pressing input transfer mechanism to the output end of the sealing depth detection mechanism, and setting the secondary shaping transfer mechanism across all cold and hot pressing conveying mechanisms and corresponding to the input mechanism of the battery tab secondary shaping device. This ensures the positioning accuracy and process continuity of the battery transfer between workstations and effectively guarantees the consistency of shaping quality.

[0013] 5. This invention, through the integrated transfer mechanism for secondary shaping and feeding of battery tabs, the direct-drive module for secondary shaping, and the turntable mechanism for secondary shaping in the battery tab secondary shaping device, combined with the tab scanning component, tab scraping and leveling component, tab pressing component, and tab insulation withstand voltage test component arranged circumferentially on the turntable mechanism, realizes centralized, multi-process cyclic operation of batteries in the secondary shaping stage. It integrates scraping, leveling, pressing and insulation withstand voltage testing into the same station cycle, avoiding equipment redundancy and cycle time extension caused by process separation, and improving shaping accuracy and test reliability.

[0014] 6. This invention achieves a high degree of automation and integration of the battery tab shaping and testing process through the integrated layout of the entire production line and the coordinated control between various devices, fundamentally solving the problems of low production efficiency, poor consistency of shaping accuracy, and insufficient testing reliability caused by the dispersion of processes and independent equipment.

[0064] In summary, the specific embodiments of the present invention are as follows:

[0065] The battery first enters the production line via the battery input conveyor belt 12 of the feeding, shaping, and testing preparation device 1. The synchronous direct-drive transfer mechanism 11 sequentially transfers the battery to the sealing edge shaping mechanism 13, the internal resistance voltage testing mechanism 14, and the sealing depth testing mechanism 15 for continuous operation. In the sealing edge shaping mechanism 13, the shaping clamping module 136 clamps the battery, the shaping support cylinder 134 drives the shaping limit plate 135 to rise, and the sealing shaping forward push cylinder 131 pushes the shaping double-head cylinder 132 to push the two shaping contacts 133 outwards towards both sides of the battery seal to complete the shaping.

[0066] The hot and cold pressing input transfer mechanism 23 transfers the battery to the hot and cold pressing conveying mechanism 21 of the battery tab primary shaping device 2. The hot and cold pressing conveying mechanism 21 carries the battery. The battery first passes through the glue application mechanism 24, which includes a glue application frame 241, a glue application lateral direct drive module 242 disposed on the glue application frame 241 near the input end of the hot and cold pressing conveying mechanism 21, a glue application component 243 disposed on the output end of the glue application lateral direct drive module 242, and a glue application component 243 disposed on the input end of the hot and cold pressing conveying mechanism 241.

The glue application speed is determined based on the detection data of the sealing depth. For batteries with a large sealing depth, the glue application displacement speed is slowed down to increase the amount of glue applied; for batteries with a shallow sealing depth, the glue application displacement speed is increased to reduce the amount of glue applied. The amount of adhesive applied is visually inspected by the CCD camera 245 driven by the horizontal direct-drive module 244. The battery is then moved to the bottom of the battery pressing and shaping mechanism 26. The battery pressing cylinder 2611 drives the sliding pressure block 2613 to press the battery body, while the roller driving cylinder 2621 drives the roller 2623 to move below the tab. The hot and cold pressing conveyor mechanism 21 drives the battery to move so that the tab passes over the roller. The roller moves upward to fold and attach the tab. The battery continues to be moved to the hot and cold pressing shaping machine.

[0067] The secondary shaping and transfer mechanism 25 transfers the battery from the hot and cold pressing transfer mechanism 21 to the secondary shaping direct drive module 32 of the battery tab secondary shaping device 3. After the secondary shaping direct drive module 32 drives the battery to the output end, the secondary shaping feeding and discharging integrated transfer mechanism 31 clamps the battery and feeds it into the battery clamping and positioning component 332 located on one side of the tab scanning component 333 in the secondary shaping turntable mechanism 33.

In the tab scanning component 333, the infrared sensor 3332 detects the tab's primary shaping status. In the tab scraping and leveling component 334, the tab support lifting cylinder 33441 of the tab support module 3344 of the tab scraping and leveling component 334 drives the tab support positioning cylinder 33441. The slider 33442 rises to support the electrode tab. The base direct drive module 3341 and the lifting direct drive module 3342 drive the leveling and sizing module 3343 to position it. The leveling scraper 334321 contacts the electrode tab with its arc end to level it. The sizing roller structure 334331 rolls and flattens it. In the electrode tab flattening assembly 335, the flattening support cylinder 3357 drives the flattening support panel 3358 to lift the electrode tab, and the forward-pushing flattening cylinder 3352 pushes the flattening frame 33. 53. The flattening cylinder 3354 drives the pressing plate 3355 to repeatedly press down on the electrode ear; in the electrode ear insulation withstand voltage test assembly 336, the test total displacement frame assembly 3361 is positioned as a whole, the electrode ear support platform component 33621 rises to lift the electrode ear, the probe pressing component 33622 presses down the probe to contact the electrode ear, and at the same time, the transverse cylinder 33632 of the cutter test assembly 3363 drives the edge sealing cutter 336344 to cut into the sealing adhesive layer to form an electrical circuit for testing;

[0068] After the secondary shaping is completed, the secondary shaping feeding and unloading integrated transfer mechanism 31 moves the battery out of the turntable to the unloading temporary holding platform 42 of the unloading device 4. Then, the synchronous unloading mechanism 41 clamps the battery on the unloading temporary holding platform 42 and enters the size detection mechanism 43. The battery's two adjacent side positioning modules 431 position the battery, the battery clamping module 432 presses against the side of the battery to complete the clamping, and the battery size detection module 433 presses against the end of the battery so that the pressure sensor reaches the threshold and detects the size data. According to the detection results, the batteries are separated by the unloading conveyor belt group 44. Good products are clamped by the synchronous unloading mechanism 41 and output through the unloading conveyor belt 442, while defective products are clamped by the synchronous unloading mechanism 41 and recycled through the defective product recycling conveyor belt 441. The entire production line realizes the fully automated continuous operation of the battery tab from feeding, detection, primary shaping, secondary shaping to unloading.
