[0027] Please see Figures 1-4One embodiment provided by this utility model:

[0028] A soft-pack battery folding machine, comprising:

[0029] The body 1 has a support frame 2 fixedly installed on its top and a positioning mechanism 3 provided on its top. The positioning mechanism 3 includes a base 5 fixedly installed on the top of the body 1 and symmetrically distributed protrusions 10 on the top of the base 5.

[0030] The support frame 2 is provided with a track 23, and a slider 21 is slidably mounted on the track 23. A folding mechanism 4 is provided at the bottom of the slider 21. A second servo motor 22 is fixedly mounted on the top of the slider 21. A gear 24 is fixedly mounted on the drive end of the second servo motor 22. A toothed plate 6 is fixedly mounted on the back of the support frame 2, and the toothed plate 6 meshes with the gear 24.

[0031] The top of the base 5 is provided with a slide rail 8, and a bidirectional lead screw 9 is rotatably installed inside the slide rail 8. The outer wall of the bidirectional lead screw 9 is fitted with symmetrically distributed adjustment blocks 11, and the adjustment blocks 11 are fixedly connected to the corresponding protrusions 10. A drive mechanism is provided on one side of the base 5, which can precisely adjust the spacing of the protrusions 10 to adapt to the processing of soft-pack batteries of different sizes.

[0032] In one embodiment, the folding mechanism 4 includes a movable frame 17 fixedly installed at the bottom of the slider 21. A cylinder 16 is fixedly installed inside the movable frame 17, and the driving end of the cylinder 16 passes through the movable frame 17 and extends to the bottom of the movable frame 17. A folding blade 19 is fixedly installed at the driving end of the cylinder 16, and a pressing block 20 is fixedly installed at the bottom of the folding blade 19. By using the cylinder 16 to drive the folding blade 19 and the pressing block 20 to move up and down, the battery folding operation can be completed flexibly and efficiently.

[0033] In one preferred embodiment, the drive mechanism includes a fixed frame 14 fixedly mounted on one side of the base 5. A worm gear 13 is rotatably mounted inside the fixed frame 14. One end of a bidirectional lead screw 9 passes through the base 5 and extends to one side of the outer surface of the base 5. A worm wheel 12 is fixedly mounted on one end of the bidirectional lead screw 9, and the worm wheel 12 meshes with the worm gear 13. A first servo motor 15 is fixedly mounted on the front side of the fixed frame 14, and the drive end of the first servo motor 15 is fixedly connected to the front end of the worm gear 13 to achieve precise transmission and stable speed regulation, which facilitates the control of the movement of the adjusting block 11.

[0034] In one embodiment, the top of the folding knife 19 is fixedly equipped with symmetrically distributed guide rods 18, and the movable frame 17 is provided with sliding holes corresponding to the position and number of the guide rods 18. The movable frame 17 is slidably connected to the guide rods 18 through the sliding holes, which can ensure that the folding knife 19 moves up and down with accurate and stable direction, avoid deviation, and improve the accuracy and quality of the folding operation.

[0035] In one preferred embodiment, the adjusting block 11 is T-shaped and is adapted to the slide rail 8, which can prevent the adjusting block 11 from falling out of the slide rail 8, ensure that the adjusting block 11 slides stably along the slide rail 8, and make the adjustment of the spacing of the protrusion block 10 more stable and reliable.

[0036] In one embodiment, the outer wall of the bidirectional lead screw 9 is provided with symmetrically distributed left-hand and right-hand threads. The adjusting block 11 is provided with a threaded hole that matches the bidirectional lead screw 9. The adjusting block 11 is threadedly connected to the bidirectional lead screw 9 through the threaded hole, which enables the two adjusting blocks 11 to move synchronously relative to each other or in opposite directions, thereby efficiently adjusting the spacing of the protrusions 10.

[0037] In one preferred embodiment, a controller 7 is fixedly installed on one side of the front of the support frame 2, and the controller 7 is electrically connected to the first servo motor 15, the cylinder 16 and the second servo motor 22 respectively through wires, which facilitates centralized control of each component, makes operation convenient, and improves the coordination and efficiency of equipment operation.

[0038] In one embodiment, anti-slip pads are adhered to the opposite surfaces of the two protrusions 10, which can increase the friction with the soft-pack battery, prevent the soft-pack battery from sliding and shifting during the folding process, and ensure processing accuracy and stability.

[0039] The working principle of this utility model is as follows: In use, the soft-pack battery is placed on top of the base 5, so that the two sides of the soft-pack battery abut against the protruding blocks 10 on both sides of the top of the base 5. Then, the second servo motor 22 is started, and its drive end drives the gear 24 to rotate. Through the meshing transmission between the gear 24 and the toothed plate 6, the slider 21 is made to move laterally stably on the track 23. The movement of the slider 21 drives the folding mechanism 4 to move synchronously until the folding mechanism 4 moves directly above the lead-out edge of one side of the soft-pack battery. At this time, the cylinder 16 is started, and its drive end drives the folding knife 19 to move. The folding knife 19 further drives the pressing block 20 to move, so that the pressing block 20 moves downward and cooperates with the protruding block 10, thereby realizing the bending operation of the lead-out edge of the soft-pack battery on that side. After completing the folding of one side, the folding mechanism 4 is controlled to move to the other side of the soft-pack battery to perform the same bending operation on the other lead-out edge. Thanks to the lateral movement of the folding mechanism 4, this equipment can perform folding processing on both sides of the soft-pack battery even when the battery position is fixed, avoiding frequent adjustments to the position of the soft-pack battery and effectively improving the folding efficiency of the soft-pack battery.

[0040] When using the protruding block 10 to limit the position of the pouch battery, the first servo motor 15 can be activated. Its drive end drives the worm gear 13 to rotate. Through the meshing transmission between the worm gear 13 and the worm wheel 12, the worm wheel 12 drives the bidirectional lead screw 9 to rotate. Based on the thread transmission principle of the left-hand and right-hand threads on the bidirectional lead screw 9, and the sliding fit between the adjusting block 11 and the slide rail 8, the two adjusting blocks 11 can stably move relative to each other or in opposite directions. The movement of the adjusting block 11 drives the protruding block 10 to move synchronously, thereby adjusting the distance between the two protruding blocks 10. Through this adjustment mechanism, the protruding block 10 can adapt to pouch batteries of different sizes and specifications, achieving effective fixation on both sides, significantly improving the versatility and practicality of the equipment.
