Embodiment two: in the production method of the linear seal nail welding production line in the first embodiment, firstly, a worker places an unprocessed electric core 9 at the material conveying belt inlet 21, when the proximity sensor 264 of the blocking device 26 above the material conveying belt inlet 21 detects the unprocessed electric core 9, the blocking rod 262 rotates, the rubber block 263 blocks the unprocessed electric core 9, and the code scanning device 27 performs code scanning record on the unprocessed electric core 9. After the recording is completed, the lever 262 is rotated, the rubber stopper 263 is removed, and the unprocessed cell 9 enters the middle part of the material conveyor 2. When the proximity sensor 264 of the dam device 26 above the middle of the material conveyor 2 detects a raw cell 9, the bar 262 rotates and the rubber stopper 263 blocks the raw cell 9.
The gripping fixture 33 grips the unprocessed cell 9 and transfers the unprocessed cell 9 to the transfer fixture 42. The transfer jig 42 slides along the transfer rail 41, and the unprocessed battery cells 9 are conveyed below the first reversing jig 53. The first switching fixture 53 clamps the unprocessed battery cells 9, and the second switching fixture 54 clamps the processed battery cells 9. The turntable 52 rotates 180 degrees, the first and second exchange clamps 53 and 54 are exchanged in position, and the processed battery cell 9 falls into the transfer clamp 42. The relay holder 42 slides along the relay guide 41, and the processed cell 9 is conveyed to the lower side of the grasping holder 33. The gripping jig 33 transfers the processed cell 9 to the middle portion of the material conveyor 2, and then the stopper 262 is rotated, the rubber stopper 263 is removed, and the processed cell 9 is carried out from the material conveyor outlet 23.
At the same time as the processed cell 9 is transferred back to the material conveyor belt 2, the opening cylinder 63 is started, the driving plate 622 of the conveying clamp 62 is pulled outward, and the short-side clamping block 624 moves outward synchronously and compresses the clamping spring one 627. The driving plate 622 drives the driven plate 623 to move synchronously, and the roller 6262 rolls out from the groove 6231, so that the second connecting rod 6261 pulls out the second long-side clamping block 625, and the second clamping spring 628 is compressed while the second long-side clamping block 625 moves outwards. Then the unprocessed battery cell 9 falls into the conveying clamp 62 from the first exchanging clamp 53, the clamping cylinder 63 is closed, the first clamping spring 627 and the second clamping spring 628 release the elastic force, the driving plate 622 moves inwards, the roller 6262 returns into the groove 6231, and the short side clamping block 624 and the long side clamping block 625 clamp and fix the unprocessed battery cell 9 under the action of the first clamping spring 627 and the second clamping spring 628.
Then, the conveying jig 62 slides along the conveying rail 61, and the unprocessed battery cells 9 are sent to the cleaning device 7. The cleaning press plate moves downwards to perform secondary positioning on the unprocessed battery cells 9, and the laser galvanometer 73 starts to remove electrolyte and other impurities possibly existing around the liquid injection holes of the battery cells 9. After the cleaning is completed, the conveying jig 62 feeds the battery cells 9 into the welding device 8. The welding positioning cylinder 812 drives the welding pressing plate 816 to move downwards to perform secondary positioning on the battery cell 9, the nail taking and placing cylinder 822 drives the vacuum chuck 823 to move downwards, and sealing nails on the nail receiving block 834 are sucked by negative pressure. The PLC controls the welding table 82 to move, the sealing nails are conveyed to the position above the battery cells 9, and the conveying process is monitored by the camera 821 in real time. After the sealing nail is conveyed in place, the vacuum chuck 823 places the sealing nail on the liquid injection hole of the battery cell 9, and the nail pressing rod 815 is pressed above the sealing nail by adjusting the first nail pressing cylinder 813 and the second nail pressing cylinder 814. And then the welding head 826 is controlled to weld the sealing nails on the liquid injection holes of the battery cells 9, and the processed battery cells 9 are returned to the initial position by the conveying clamp 62. Because the time for conveying the unprocessed battery cells 9 is the same as the time for processing the battery cells 9, at this time, the grabbing device 3 just conveys the next unprocessed battery cell 9 to the exchanging device 5, and the processed battery cells 9 just exchange positions with the next unprocessed battery cells 9, so that the processing of the next battery cells 9 is continued.
According to the embodiment, the raw battery cell enters from the inlet of the material conveying belt and is blocked by the blocking device. The gripping device then transfers it to the first and second reversing jigs for gripping the processed cells. The turntable can realize the position exchange between the first exchange clamp and the second exchange clamp. After the battery cell is conveyed by the grabbing device, the processed battery cell is conveyed to the material conveying belt during return stroke. At this time, the stop device is automatically opened, and the processed battery cell is smoothly transported out from the outlet of the material conveying belt. In summary, on the premise of ensuring the efficiency, the material conveyor belt disclosed by the invention realizes synchronous feeding and discharging, reduces the requirement of the conveyor belt, and saves the cost and the space. The method not only simplifies equipment maintenance and fault elimination, but also lays a foundation for future production line improvement or expansion, and creates favorable conditions for long-term development of enterprises.
