[0031] The working principle of the present invention: Place the battery string to be welded in the material box 14. The material taking motor 34 works under the control of the control system. Utilize the meshing transmission of the helical gear I 35 and the helical rack, and drive the material taking suction nozzle 37 to the upper part of the material box 14 through the substrate I 31. The material taking cylinder 33 works and presses down the material taking suction nozzle 37. After pressing down in place, the material taking suction nozzle 37 starts to adsorb the battery string through the connected negative pressure system. After reaching the negative pressure value, the material taking cylinder 33 lifts the material taking suction nozzle 37, so that the battery string is taken out from the material box 14. After the material taking cylinder 33 resets, the material taking motor 34 moves the material taking suction nozzle 37 to the upper part of the alignment part 9 again through the substrate I 31.

[0032] Before the pick-up nozzle 37 places the battery string downward, the correction cylinder 92 operates and extends its cylinder rod, causing the support four 94 to drive the deflector 95 away from the alignment plate 97. Then, the pick-up cylinder 33 presses down the pick-up nozzle 37, and the pick-up nozzle 37 places the battery strings one by one on the correction plate 96 and on both sides of the alignment plate 97. During the placement process, the pick-up motor 34 cooperates to adjust the position of the pick-up nozzle 37. After the battery strings are placed on the correction plate 96, the pick-up nozzle 37 resets, and the correction cylinder 92 retracts its cylinder rod, using the support four 94 to drive the deflector 95 to correct the battery strings, aligning the two battery strings. After the battery strings are aligned, the correction cylinder 92 extends its cylinder rod again, causing the deflector 95 to move away from the battery strings, facilitating the pick-up nozzle 37 to pick up the battery strings. The pick-up cylinder 33 presses down the pick-up nozzle 37 again, and the pick-up nozzle 37 adsorbs the battery strings again. After the battery strings are picked up, the pick-up cylinder 33 resets, and the pick-up motor 34 drives the pick-up nozzle 37 to move above the pallet 15.

[0033] After the pick-up nozzle 37 moves above the pallet 15, the pick-up cylinder 33 presses down the pick-up nozzle 37, and the pick-up nozzle 37 arranges the battery strings in an orderly manner on the pallet 15. Then, the pick-up cylinder 33 pulls the pick-up nozzle 37 to reset, and the pick-up motor 34 drives the entire string handling unit 3 to move back. According to production requirements, different numbers of battery strings can be selected for placement. The pick-up motor 34 can drive the pick-up nozzle 37 to continue picking up battery strings and placing them on the pallet 15, or the pick-up motor 34 can bring the pick-up nozzle 37 back to the original position to reset and wait for the next execution command.

[0034] When the battery string is transported by the string handling section 3, the unwinding motor 43 operates to drive the solder tape reel 42 to release the solder tape. After the solder tape bypasses the guide roller 44 and the guide wheel 45, it bypasses the tape outlet wheel 46 again and flows towards the tape inlet wheel 57. After the solder tape bypasses the tape inlet wheel 57, it passes through the second traction section 59 and the cutting section 510 in sequence. When the solder tape does not need to be cut, the cylinder rod of the clamping cylinder 515 of the second traction section 59 extends, and the clamping jaw 516 cooperates with the clamping bracket to clamp the solder tape, preventing the solder tape from slipping out of the cutting section 510 and the second traction section 59. When the solder tape needs to be cut, the pressing tape cylinder 54 operates and drives the pressing plate to rotate and rise to one side through the cylinder rod. The pressing plate vacates the space for the solder tape to fall on the solder tape table 53. The belt synchronous belt drive structure three 52 drives the first traction section 58 to slide on the slide rail 513 and move closer to the cutting section 510. At this time, the pushing cylinder 56 drives the cutting section 510 to move towards the second traction section 59, so that a section of the solder tape is exposed from the cutting section 510, facilitating the first traction section 58 to clamp the solder tape. After the first traction section 58 moves into place and clamps the solder tape, the clamping cylinder 515 of the second traction section 59 acts to reset and no longer clamps the solder tape. The belt synchronous belt drive structure three 52 drives the first traction section 58 to move back again, and the pushing cylinder 56 pushes the cutting section 510 back to its original position. When the length of the solder tape reaches the cutting length, the belt synchronous belt drive structure three 52 stops moving, and the second traction section 59 clamps the solder tape again. The cutting section 510 realizes the cutting of the solder tape through the cutting cylinder 517, the cutting knife 519 and the cutting plate. After the solder tape is cut into segments, most of the cut solder tape segments fall on the solder tape table 53. The belt synchronous belt drive structure three 52 cooperates with the first traction section 58 to move the solder tape to the corresponding position. After the solder tape moves into place, the corresponding pressing tape cylinder 54 operates and rotates and lowers the pressing plate back through the cylinder rod, so that the pressing plate presses the solder tape to prevent the solder tape from falling off the solder tape table 53, and the first traction section 58 releases the solder tape; then according to the solder tape cutting requirements, the belt synchronous belt drive structure three 52 drives the first traction section 58 to move towards the cutting section 510 multiple times and clamp and pull the solder tape, and the second traction section 59 and the cutting section 510 cooperate with each other to realize multiple cuts of the solder tape, or the belt synchronous belt drive structure three 52 drives the first traction section 58 to reset, vacating the space for the solder tape handling section 6 to suck and handle the solder tape.

[0035] After the battery string is placed on the pallet 15, the pressing belt cylinder 54 operates and rotates the cylinder rod to rise and reset. The pressing plate lifts and releases the welding tape. After the pressing plate rises, the space above the welding tape for suction is vacated. The tape-taking cylinder 67 operates and retracts the cylinder rod, causing the tape-taking suction nozzle 69 to be located above the welding tape. Then, the belt synchronous belt drive structure 63 drives the mounting plate 64 to move downward. The mounting plate 64 drives the bracket five 65, the connecting plate 66, and the bracket six 68 to move synchronously, causing the tape-taking suction nozzle 69 to move downward and contact the welding tape. Then, the tape-taking suction nozzle 69 generates negative pressure through the negative pressure system and sucks the welding tape. Then, the belt synchronous belt drive structure 63 drives the mounting plate 64 to lift upward, causing the welding tape to leave the welding tape table 53 under the drive of the tape-taking suction nozzle 69. The tape-taking cylinder 67 operates and extends the cylinder rod outward, causing the tape-taking suction nozzle 69 to move to above the pallet 15 under the drive of the bracket six 68, so that the welding tape can be placed on the grid lines of the battery string. After the tape-taking suction nozzle 69 moves into place, the belt synchronous belt drive structure 63 drives the mounting plate 64 to move downward, enabling the tape-taking suction nozzle 69 to place the welding tape on the grid lines of the battery string and the pallet 15. After the welding tape is placed, the belt synchronous belt drive structure 63 drives the tape-taking suction nozzle 69 to rise, and the tape-taking cylinder 67 drives the tape-taking suction nozzle 69 to reset. According to production requirements, the tape-taking cylinder 67 and the belt synchronous belt drive structure 63 cooperate with each other to drive the tape-taking suction nozzle 69 to suck and place the welding tape multiple times or once.

[0036] After the welding tape is placed, the battery string handling unit 7 starts to work. The handling motor 78 drives the substrate two 71 to move through the meshing transmission of the bevel gear two 79 and the rack. The bottom plate 74 drives the bracket two 75 and the bracket three 76 to move, causing the pressure needle 710 and the vacuum component 77 to move above the battery string and the welding tape. The vertical module 72 drives the bottom plate 74 to move downward, causing the pressure needle 710 to press on the welding point between the welding tape and the grid lines of the battery string, and causing the vacuum component 77 to press on the battery string. Then, the welding unit 8 works. The belt synchronous belt drive structure 83 drives the carrier plate 84 to move, causing the welding box 86 to move to the welding point between the welding tape and the grid lines of the battery string. After moving into place, the welding cylinder 85 operates and pushes the welding box 86 upward, enabling the electromagnetic welding part 87 to perform electromagnetic welding on the welding point between the welding tape and the grid lines of the battery string. The electromagnetic welding part 87 works, causing the welding point between the welding tape and the grid lines of the battery string to complete electromagnetic welding, and the pressure needle 710 performs pressure holding on the welding point. After welding is completed, the welding cylinder 85 resets, and the belt synchronous belt drive structure 83 drives the carrier plate 84 to reset.

[0037] After maintaining pressure for a period of time, the vacuum component 77 operates to adsorb the battery string under negative pressure. The vertical module 72 drives the bottom plate 74 to rise, lifting the welded battery pack away from the pallet 15. Then, the handling motor 78 operates to move the battery pack above the plate conveyor belt 13. After moving into position, the vertical module 72 lowers the bottom plate 74 again, allowing the vacuum component 77 to place the battery pack on the glass plate 11 of the plate conveyor belt 13. After placement is complete, the vacuum component 77 releases the negative pressure, and the vertical module 72 drives the bottom plate 74 to rise and reset. The baffle cylinder 12 operates to retract the cylinder rod, and the plate conveyor belt 13 operates to convey the glass plate 11 carrying the battery pack to the production line, completing the unloading of the battery pack. After the glass plate 11 moves out of the plate conveyor belt 13, the baffle cylinder 12 resets, and the subsequent production line conveys the empty glass plate 11 to the plate conveyor belt 13 again, completing the loading of the glass plate 11.
