Description

Technical Field

[0001] This invention relates to the field of battery cell heat insulation film bonding technology, specifically a battery cell heat insulation film bonding production line based on a magnetic levitation conveyor line. Background Technology

[0002] As the core energy unit of electric vehicles, the assembly process of power battery modules has extremely high requirements for precision, efficiency, and cleanliness, directly affecting the overall performance and safety reliability of the battery pack. A typical module production line usually includes multiple stations such as cell loading, welding, gluing, stacking, end plate and side plate fastening, heat insulation film pasting, and module unloading.

[0003] Currently, the industry commonly uses traditional methods such as roller conveyors, chain conveyors, or AGVs to transport battery cells or modules between workstations. However, in the critical process of applying the heat insulation film to the battery cells, these methods have several inherent drawbacks: High risk of mechanical contact contamination: Friction between the conveyor belt or chain and the tooling pallet can easily generate micron-sized dust. In a dry and clean production environment, the dust can easily disperse and adhere to the surface of the battery cell or the uncured heat insulation film adhesive layer, which seriously affects the bonding strength and may introduce safety hazards. Vibration and shock interference: The vibration and shock generated by the traditional mechanical transmission system during start-up, shutdown or operation can easily cause slight displacement of the initially stacked modules, which in turn can cause the heat insulation film to shift, wrinkle, or even induce damage to the internal microstructure of the battery. Insufficient production line flexibility: The existing transmission system has a fixed layout, and the adjustment is complicated, making it difficult to quickly adapt to different sizes of battery cell modules and diverse heat insulation film specifications, which restricts the demand for flexible production of multiple varieties and small batches.

[0004] Therefore, it is necessary to provide a battery cell heat insulation film bonding production line based on a magnetic levitation conveyor line to solve the above problems. Summary of the Invention

[0029] In one embodiment, the process flow of the production line

[0030] Specifically, S1: Cell loading

[0031] Once the battery cell stacking or steel strip installation is completed, the central control system sends a request to transport the pallet 11 to the module placement area. The central control system sends a movement command to the target mover 12 and the corresponding track path. Under magnetic levitation drive, the mover 12 drives the pallet 11 to move smoothly and at high speed to the loading area 101. The robot picks up the battery module 8 from the previous workstation and places it on the pallet 11.

[0032] S2: Loading and peeling of heat insulation film

[0033] The PLC sends a loading request, and the worker loads the heat insulation film 9 into the rotating loading table 7. The rotating loading table 7 rotates to bring the corresponding surface of the heat insulation film 9 into the equipment to complete the loading. Then, the conveying system 2 and the film-tearing station 4 are controlled. The conveying system 2 controls the Z-axis moving module 23 to descend, and the suction cup gripper 3 also descends at the same time, so that the heat insulation film 9 is attached to the suction cup gripper 3. The vacuum suction cup 32 on the suction cup gripper 3 starts to draw a vacuum, so that the heat insulation film 9 is fully picked up by the suction cup gripper 3. The z-axis moving module 23 is raised, the x-axis moving module 22 moves, and the z-axis moving module 23 is lowered to the tearing point. The cylinder 45 is raised, which drives the lower pressure plate 46 to move upward and close to the upper pressure plate 47 to clamp the ear side 911 of the release paper 91. By controlling the y-axis moving module 21 and the z-axis moving module 23, the suction cup gripper 3 is moved to the upper left. The cylinder 45 is controlled to descend and tear open part of the release paper 91. At this time, the x-axis tearing moving module 41 is activated. The x-axis tearing moving module 41 drives the lever 44 to enter from the opening of the heat insulation film 9 and move between the heat insulation film 9 and the release paper 91. At this time, under the peeling of the lever 44, the heat insulation film 9 and the release paper 91 are separated, and the release paper 91 falls into the recycling box 42. The transport system 2 is restarted, moving the heat insulation film 9 (after being peeled off) to the positioning station 5. The suction cup gripper 3 breaks the vacuum and moves upward. The suction cup gripper 3 of the transport system 2 is controlled to move back to the initial position. The x-axis positioning moving module 56 drives the x-axis positioning moving block 54 to move closer to the x-axis positioning fixed block 58. The y-axis positioning moving module 55 drives the y-axis positioning moving block 53 to move closer to the y-axis positioning fixed block 57. The x-axis positioning moving block 54 and the y-axis positioning moving block 53 push the heat insulation film 9 closer to the corresponding positioning fixed block, thus positioning the heat insulation film 9 to the determined position for the second time. After the positioning is completed, the x-axis positioning moving block 54 and the y-axis positioning moving block 53 are reset to the initial position.

[0034] S3: Heat insulation film application

[0035] The central control system sends a request to transport tray 11 to the film application area 102. The central control system sends movement commands to the target mover 12 and the corresponding track path. Mover 12 moves to the film application area 102 under magnetic levitation drive. Collaborative robot 6 moves from the origin to the positioning station 5. The sponge suction cup 61 of the adhesive application system of collaborative robot 6 picks up the heat insulation film 9 at the positioning station 5. The negative pressure value reaches more than -60Kpa, so that the heat insulation film 9 is fully picked up. Collaborative robot 6 grabs the heat insulation film 9 and puts it into the film application area 102 on the magnetic levitation tray 11. Collaborative robot 6 controls sponge suction cup 61 to apply film to battery module 8. After the film application is completed, collaborative robot 6 returns to the origin.

[0036] S4: CCD Detection

[0037] The tray 11 is transported to the inspection area 103. The CCD camera 15 on the magnetic levitation conveyor line 1 takes pictures of the battery cell, visually inspects the surface residue and surface damage. The heat insulation film 9 that is visually judged as NG is automatically discharged, and the visual inspection image is saved locally. The OK / NG result is uploaded to MES.

[0038] S5: Module unloading and pallet return

[0039] The central control system sends a demand request to transport pallet 11 to module off-line area 104. The central control system sends movement commands to target mover 12 and the corresponding track path. Driven by magnetic levitation, mover 12 smoothly and at high speed to module off-line area 104. The three-axis gripper at the next station picks up the battery cell from pallet 11 on magnetic levitation conveyor line 1 and moves it to the next station. Empty pallet 11 automatically returns to loading area 101 under magnetic levitation drive to start a new cycle.

[0040] In summary, this magnetic levitation conveyor line 1 uses magnetic levitation transmission technology to bond the cell heat insulation film 9 of the battery module 8, fundamentally eliminating dust generated by mechanical friction, greatly improving the cleanliness and safety of the battery. At the same time, it avoids mechanical transmission, eliminates the impact of vibration on precision processes, ensures the absolute accuracy of the heat insulation film 9 bonding, eliminates wrinkling and misalignment, and significantly improves the quality consistency and yield of the heat insulation film 9 bonding process. Through the central control system software instructions, the movement and start / stop of the pallet 11 driven by the mover 12 can be quickly adjusted, easily adapting to the rapid changeover of modules and films of different sizes, greatly improving the flexibility of the module production line.
