[0046] A first gear 44 is fixedly mounted on one end of the rotating shaft 42, a servo motor 45 is fixedly mounted on the upper surface of the device bottom plate 1, a first rotating rod 46 is fixedly mounted on the driving output end of the servo motor 45, a first sector gear 47 is fixedly mounted on the end of the first rotating rod 46 away from the servo motor 45, the first sector gear 47 is meshed and connected with the first gear 44, an end of the first rotating rod 46 close to the first sector gear 47 is fixedly connected to the axis of the second sector gear 75, and by turning on the servo motor 45, the driving shaft of the servo motor 45 can be rotated through the first rotating rod 46 The first sector gear 47 is rotated (the first sector gear 47 rotates counterclockwise), the first sector gear 47 drives the first gear 44 to rotate toward one side of the supporting mechanism 5, and the first gear 44 causes the multiple U-shaped jackets 43 to rotate in a circle toward one side of the supporting mechanism 5 through the rotating shaft 42. When the first rotating rod 46 rotates, the first rotating rod 46 can make the second sector gear 75 rotate synchronously. When the first sector gear 47 is disengaged from the first gear 44 and a coated lithium battery 100 enters the top of the supporting mechanism 5, the second sector gear 75 engages with the second gear 74.

[0047] The supporting mechanism 5 includes two first side plates 51, which are fixedly mounted on the upper surface of the device bottom plate 1, and the two first side plates 51 are located between the two U-shaped folding pressure plates 81. A number of evenly distributed first rotating shafts 52 are rotatably mounted between the two first side plates 51, and passive rollers 53 are fixedly mounted on the first rotating shafts 52. The passive rollers 53 correspond horizontally to the conveyor belt of the discharge conveyor 3. By setting the first rotating shafts 52 and the passive rollers 53, the passive rollers 53 can support the stationary coated lithium battery 100 so that it stays on the passive rollers 53 for the two U-shaped folding pressure plates 81 to perform folding processing.

[0048] A second side plate 54 is fixedly installed at one end of the two first side plates 51, and the two second side plates 54 are tilted upward. A number of evenly distributed second rotating shafts 55 are rotatably installed between the two second side plates 54, and active rollers 56 are fixedly installed on the number of second rotating shafts 55. By setting the inclined second side plates 54 and active rollers 56, when the two horizontally corresponding U-shaped jackets 43 rotate downward in a circle, in this process, the coated lithium batteries 100 in the two U-shaped jackets 43 slide onto the active rollers 56, and slide along the multiple active rollers 56 onto the multiple passive rollers 53, and the coated lithium batteries 100 cause the active rollers 56 to rotate during the sliding process.

[0049] One end of each of the two second rotating shafts 55 is fixedly mounted with a first synchronous wheel 57, a first synchronous belt 58 is installed between the two first synchronous wheels 57, one end of each of the second rotating shafts 55 and one end of the first rotating shaft 52 is fixedly mounted with a transmission wheel 59, a transmission belt 591 is installed between the two transmission wheels 59, and by arranging the first synchronous wheel 57, the first synchronous belt 58, the transmission wheel 59 and the transmission belt 591, when the active roller 56 rotates, the second rotating shafts 55 at both ends of the second side plate 54 rotate synchronously, and one of the second rotating shafts 55 can pass through the two transmission wheels 5 9 and the transmission belt 591 cause one of the first rotating shafts 52 and a passive roller 53 to rotate. During the rotation process, the passive roller 53 transmits the slipped coated lithium battery 100 so that the coated lithium battery 100 is just located directly below the two U-shaped folding pressure plates 81. At the same time, the rotating passive roller 53 does not separate from the coated lithium battery 100. When the next coated lithium battery 100 to be folded slides down through the active roller 56, the rotation of the active roller 56 causes the passive roller 53 to rotate again, and the passive roller 53 transmits the folded coated lithium battery 100 to the conveyor belt of the discharge conveyor 3.

[0050] Working principle: After the lithium battery is packaged by the packaging equipment, a coated lithium battery 100 is formed. When the coated lithium battery 100 needs to be folded, the operator first operates the feed conveyor 2, and the conveyor belt of the feed conveyor 2 starts to convey multiple coated lithium batteries 100. When the conveyor belt of the feed conveyor 2 conveys a coated lithium battery 100 to the end of the conveyor belt, a coated lithium battery 100 enters two horizontally corresponding U-shaped jackets 43. At this time, the operator turns on the servo motor 45;

[0051] The driving shaft of the servo motor 45 rotates the first sector gear 47 counterclockwise through the first rotating rod 46, and the first sector gear 47 rotates the rotating shaft 42 through the first gear 44. The rotating shaft 42 causes the multiple U-shaped jackets 43 to rotate in a circle toward one side of the supporting mechanism 5, and the coated lithium battery 100 rotates in a synchronous circle.

[0052] During the circular rotation, when the coated lithium battery 100 tilts downward, under the influence of gravity, the coated lithium battery 100 is separated from the two horizontally corresponding U-shaped jackets 43 and falls on multiple active rollers 56. The coated lithium battery 100 slides downward along the multiple active rollers 56 to the multiple passive rollers 53. In this process, the coated lithium battery 100 sliding downward causes the multiple active rollers 56 and the multiple second rotating shafts 55 to rotate. One of the second rotating shafts 55 rotates a first rotating shaft 52 and a passive roller 53 through two transmission wheels 59 and a transmission belt 591. The rotation of a passive roller 53 transmits the coated lithium battery 100. When the coated lithium battery 100 is completely separated from the multiple active rollers 56, a passive roller 5 3 stops rotating, and transfers the coated lithium battery 100 to the bottom of the two U-shaped folding plates 81. When the folding process of one coated lithium battery 100 is completed, the other coated lithium battery 100 to be folded continues to drive the active roller 56 to rotate during the sliding process, so that a passive roller 53 rotates again. The rotation of the passive roller 53 transports the coated lithium battery 100 after the folding process to the conveyor belt of the unloading conveyor 3, and the unloading conveyor 3 transports the coated lithium battery 100 after the folding process to the next processing station, thereby conveniently realizing the automatic transportation of the coated lithium battery 100 before and after the folding process, thereby effectively improving the automation degree of the lithium battery folding processing device, and effectively improving the overall processing efficiency of the lithium battery;

[0053] When the coated lithium battery 100 to be folded is located directly below the two U-shaped folding pressure plates 81, the rotation of the first rotating rod 46 causes the second sector gear 75 to mesh with the second gear 74 and drive the second gear 74 to rotate, and the second gear 74 causes the third rotating rod 73 to rotate, and the third rotating rod 73 causes the corresponding second rotating rod 66 to rotate through two third synchronous wheels 76 and the third synchronous belt 77, and one second rotating rod 66 causes the transmission rod 7 to rotate through two second synchronous wheels 71 and the second synchronous belt 72, and the transmission rod 7 causes another second rotating rod 66 to rotate synchronously in the same direction through the other two second synchronous wheels 71 and the second synchronous belt 72. At this time, the two second rotating rods 66 are connected to the two second synchronous wheels 71 and the second synchronous belt 72. A bevel gear 67 and two second bevel gears 69 make the two shafts 64 rotate synchronously in opposite directions. The two shafts 64 make the four blades 61 and the two folding rollers 63 rotate in a circle around the axis of the corresponding shaft 64 through four mounting seats 65, and two adjacent blades 61 rotate in a circle toward the side of the coated lithium battery 100 at the same time. When the cutting ends of the four blades 61 contact the excess aluminum-plastic film on both sides of the coated lithium battery 100, the four blades 61 cut off the excess aluminum-plastic film on both sides of the coated lithium battery 100 (cutting in the horizontal direction). At the same time, the two folding rollers 63 follow closely behind, contact the cut aluminum-plastic film, and press the aluminum-plastic film against the side of the coated lithium battery 100.

[0054] At the same time, the transmission rod 7 makes the corresponding fifth rotating rod 85 rotate synchronously through the two fifth synchronous wheels 93 and the fifth synchronous belt 94, and the fifth rotating rod 85 makes the other fifth rotating rod 85 rotate synchronously through the two fourth synchronous wheels 91 and the fourth synchronous belt 92. At this time, the two fifth rotating rods 85 make the two driving rods 87 rotate in a circle through the two driving handles 86, and the two driving rods 87 make the two U-shaped connecting frames 89 and the U-shaped folding edge pressing plates 81 approach each other and move away from each other through the two push-pull rods 88 and the two connecting seats 9. In the process of the two U-shaped folding edge pressing plates 81 approaching each other, the inner sides of the two U-shaped folding edge pressing plates 81 contact the excess aluminum-plastic film on the upper and lower surfaces of the coated lithium battery 100, and the excess aluminum-plastic film on the upper and lower surfaces is pressed tightly against the side edges of the coated lithium battery 100, thereby conveniently realizing the multi-sided automatic synchronous folding processing in the folding processing of the coated lithium battery 100. Compared with the existing technology, the efficiency of the folding processing of the coated lithium battery 100 is effectively improved, the number of folding equipment is reduced, and the equipment cost is saved.
