Description

Technical Field

[0001] This invention relates to the field of product packaging technology, and in particular to a finished lithium battery pack packaging mechanism. Background Technology

[0002] A lithium battery pack, or lithium battery stack, generally refers to a product composed of multiple battery groups and equipped with battery management systems. After the internal battery groups are connected in various ways, they need to be packaged to ensure a more stable connection and a more aesthetically pleasing appearance. Applying a protective film to the lithium battery pack is one such packaging method. Currently, when applying the protective film to lithium battery packs, multiple transfers, flips, and changes in posture are required to ensure proper coverage of all ends of the lithium batteries. Then, the film is squeezed and applied to each end. However, the continuity of these transfers, flips, and changes in posture is poor, requiring more time and resulting in low efficiency. Furthermore, it is difficult to continuously squeeze and apply the film again during this process, leading to a short application time, which is not conducive to eliminating bulges and fails to improve the application effect, highlighting the shortcomings of existing technology. Summary of the Invention

[0003] The purpose of this invention is to provide a finished lithium battery pack packaging mechanism to solve the above-mentioned technical problems.

[0004] This invention is only suitable for applying films to rectangular block-shaped lithium battery packs. To achieve the above objectives, this invention adopts the following technical solution:

[0005] A lithium battery pack packaging mechanism includes a base. From right to left, the base is equipped with a pushing mechanism, a winding mechanism, a transfer mechanism, and an applicating mechanism. The base also has a controller and a straightening mechanism fixed to it. The winding mechanism includes a right support roller, a first support base, a main guide rod, a bidirectional lead screw, a support, a support shaft, a rotation damper, a support cone, a first support frame, a second support frame, a first electric push rod, an upper cone plate, an upper auxiliary pressure roller, a second electric push rod, a second lifting seat, a lower cone plate, a third electric push rod, a support platform, a cutter, a third clamping plate, and a lower auxiliary pressure roller. Multiple horizontal right support rollers are rotatably connected to the right side of the base in the front-rear direction. All right support rollers are located on the same horizontal plane. Two mirror-image first support rollers are fixed to the right side of the base. The support base has two No. 1 support bases with a horizontal main guide rod fixed to their upper parts. A horizontal bidirectional lead screw is rotatably connected to the upper parts of both No. 1 support bases. Supports are slidably connected to the front and rear ends of each main guide rod. Horizontal support shafts are rotatably connected to the left sides of each support base. The two support shafts are coaxial. A rotation damper is installed between each support shaft and support base. The rotation damper increases the resistance during rotation. Support cones are coaxially fixed to adjacent ends of each support shaft. A vertical No. 1 support frame is fixed to the upper right of the base. A vertical No. 2 support frame is fixed to the lower right of the base. A vertical No. 1 electric push rod is fixed to the top of the No. 1 support frame. An upper conical plate is fixed to the bottom end of the push rod of the No. 1 electric push rod. The left end face of the plate is vertical, and the right end is inclined downward to the left. The left and right end faces of the upper conical plate have a smooth transition at the bottom. A horizontal upper auxiliary pressure roller is rotatably connected to the upper left part of the upper conical plate in the front-back direction. A vertical second electric push rod is fixed to the bottom end of the second support frame. A second lifting seat is fixed to the top of the push rod of the second electric push rod. A lower conical plate is fixed to the right side of the second lifting seat. A horizontal third electric push rod is fixed to the right end of the lower conical plate in the left-right direction. The upper left end face of the lower conical plate is inclined to match the right end face of the upper conical plate. A horizontal support platform is fixed to the upper middle part of the left end of the lower conical plate in the front-back direction. A strip-shaped cutter is fixed to the top of the support platform in the front-back direction. A vertical... The No. 3 clamping plate has an upper right end face that is inclined to match the upper left end face of the lower conical plate. A horizontal lower auxiliary pressure roller is rotatably connected to the upper left part of the No. 3 clamping plate in the front-back direction. The distance between the leftmost edge of the outer circumference of the lower auxiliary pressure roller and the leftmost edge of the outer circumference of the upper auxiliary pressure roller is equal to the thickness of the blue film. The leftmost edge of the outer circumference of the lower auxiliary pressure roller is located to the left of the leftmost edge of the outer circumference of the upper auxiliary pressure roller. The top surface of the No. 3 clamping plate smoothly transitions to its left and right end faces. The transfer mechanism includes a main servo motor, a mounting base, an upper pressure roller, a lower pressure roller, a top block, a main guide block, a receiving groove, a No. 4 electric push rod, and a No. 4 clamping plate. A vertical main servo motor with a braking function is fixed in the middle of the base. A horizontal mounting base is fixed to the top of the shaft of the main servo motor.A set of multiple upper pressure rollers is rotatably connected to the upper part of the mounting base, and a set of multiple lower pressure rollers is rotatably connected to the bottom of the mounting base. A horizontal top block, rectangular in shape, is placed between the upper and lower pressure rollers. All the upper pressure rollers are positioned on the same horizontal plane and arranged along the front-to-back direction, as are all the lower pressure rollers. The highest point of the outer circumferential wall of each lower pressure roller is at the same height as the highest point of the outer circumferential wall of the right support roller. Horizontal guide blocks are fixed at both the front and rear ends of the inner wall of the mounting base. Both guide blocks have horizontal guide blocks on their left and right sides. Shaped like an arrow, the main guide block is located between the upper and lower pressure rollers. The top block's upper and lower ends roll and rub against the upper and lower pressure rollers respectively. The front and rear ends of the top block contact and abut the adjacent ends of the two main guide blocks, ensuring that the width and height of the top block are consistent with the width and height of the lithium battery pack after only one layer of blue film is applied. Horizontal receiving grooves extend through the middle of each of the two main guide blocks. Horizontal No. 4 electric push rods are fixed at both the front and rear ends of the mounting base, and horizontal No. 4 clamping plates are fixed to the ends of the push rods of the two No. 4 electric push rods respectively.

[0006] Based on the above technical solution, the application mechanism includes a No. 5 electric push rod, a No. 5 lifting seat, a No. 6 electric push rod, an upper pressure plate, a side pressure plate, a No. 7 electric push rod, a No. 7 lifting seat, a left support roller, and a secondary guide block. A vertical No. 5 electric push rod is fixed to the top left of the base. A No. 5 lifting seat is fixed to the bottom of the push rod of the No. 5 electric push rod. Vertical No. 6 electric push rods are fixed to the left and right sides of the top of the No. 5 lifting seat. A horizontal upper pressure plate is fixed to the bottom of the push rod of the No. 6 electric push rod. Vertical side pressure plates are fixed to the front and rear ends of the inner wall of the left side of the base. The lower left part of the base is fixed with… There is a vertical No. 7 electric push rod. A horizontal No. 7 lifting seat is fixed to the top of the push rod. A set of multiple left rollers rotates on the upper part of the No. 7 lifting seat. The left rollers are all in the same horizontal plane in the front-back direction. Horizontal secondary guide blocks are fixed at both ends of the left inner wall of the base. The right part of the secondary guide blocks is arrow-shaped. The two secondary guide blocks are at the same height as the two main guide blocks. The height of the secondary guide blocks and the main guide blocks should be slightly less than the height of the lithium battery pack. The distance between the two secondary guide blocks should be close to the sum of the width of the lithium battery pack and the thickness of the four blue film layers.

[0007] Based on the above technical solution, the pushing mechanism includes an eighth electric push rod, a push plate, a ninth electric push rod, a right moving seat, and guide rollers. The right end of the base is fixed with a horizontal eighth electric push rod, the left end of the push rod of the eighth electric push rod is fixed with a horizontal push plate, the opposite ends of the two first support seats are respectively fixed with horizontal ninth electric push rods, the push rod ends of the two ninth electric push rods are respectively fixed with horizontal right moving seats, and the two right moving seats are respectively rotatably connected to a set of multiple guide rollers. The two sets of guide rollers are vertical and located in two positive planes.

[0008] Based on the above technical solution, the correction mechanism includes a No. 10 electric push rod, a left moving seat, a secondary servo motor, and rollers. The front and rear ends of the left side of the base are each fixed with a horizontal No. 10 electric push rod. The push rod end of the No. 10 electric push rod is fixed with a left moving seat. The top of the two left moving seats are respectively fixed with multiple vertical secondary servo motors with braking function. The two left moving seats are rotatably connected to a set of multiple rollers. The two sets of rollers are respectively located in two positive planes. The rollers are coaxially fixed with the rotation shaft of the secondary servo motor.

[0009] Based on the above technical solution, sponge pads are fixed to the adjacent ends of the two No. 4 clamps respectively. The No. 4 clamps and sponge pads can be accommodated in the receiving groove. The left parts of the two left moving seats are respectively rotatably connected to vertical application rollers. Vertical auxiliary light rods are fixed to the top of the upper cone plate and the bottom of the No. 7 lifting seat respectively. The auxiliary light rod at the top of the upper cone plate is slidably connected to the No. 1 support frame. The auxiliary light rod at the bottom of the No. 7 lifting seat is slidably connected to the base. A handwheel is coaxially fixed in the middle of the bidirectional lead screw.

[0010] Based on the above technical solution, the controller is electrically connected to the first, second, and third electric push rods, the main servo motor, the fourth, fifth, sixth, seventh, eighth, ninth, and tenth electric push rods, and the auxiliary servo motor. The controller is powered by an external power source. When the first electric push rod is energized, its extension and retraction mechanism can move the upper cone plate up and down. When the second electric push rod is energized, its extension and retraction mechanism can move the second lifting seat up and down. When the upper and lower cone plates are close to a certain position, the smooth transition point at the bottom of the upper cone plate contacts the tip of the cutter. When the smooth transition point at the bottom of the upper cone plate contacts the tip of the cutter, the right end face of the upper cone plate contacts the lower cone plate. There is a gap between the upper left end faces that is no greater than the thickness of the blue film. When the No. 3 electric push rod is energized and retracts, it can drive the No. 3 clamping plate to move left and right. When the No. 4 electric push rod is energized and retracts, it can drive the No. 4 clamping plate to move back and forth. When the No. 5 electric push rod is energized and retracts, it can drive the No. 5 lifting seat to move up and down. When the No. 6 electric push rod is energized and retracts, it can drive the upper pressure plate to move up and down. When the No. 7 electric push rod is energized and retracts, it can drive the No. 7 lifting seat to move up and down. When the No. 8 electric push rod is energized and retracts, it can drive the push plate to move left and right. When the No. 9 electric push rod is energized and retracts, it can drive the right moving seat to move back and forth. When the No. 10 electric push rod is energized and retracts, it can drive the left moving seat to move back and forth.

[0011] Compared with the prior art, the present invention has the following advantages: In the process of applying film to lithium battery packs, the present invention only needs to control the main servo motor to move the lithium battery pack once, without having to move, flip and change the posture of the lithium battery pack multiple times, which has good continuity, reduces time consumption and improves film application efficiency.

[0012] When the lithium battery pack enters and exits the mounting base (i.e., during transfer), its top and bottom ends are pressed twice by multiple upper and lower pressure rollers, extending the application time. The top block, upper auxiliary pressure roller, and lower auxiliary pressure roller can respectively compress the blue film at the left and right ends of the lithium battery pack. The main guide block, auxiliary guide block, No. 5 lifting seat, and side pressure plate can compress the blue film at the front and rear ends of the lithium battery pack, and the application roller can perform roll pressing and application, further extending the application time. This ensures that the blue film on all six ends of the lithium battery pack (top, bottom, left, right, front, and rear) adheres more fully to the lithium battery, reducing bulging and improving the application effect.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-9As shown, a lithium battery PACK finished product packaging mechanism includes a base 101. From right to left, the base 101 is equipped with a pushing mechanism 1, a winding mechanism 2, a transfer mechanism 3, and an applicating mechanism 4. The base 101 also has a controller 5 and a straightening mechanism 6 fixed to it. The winding mechanism 2 includes a right support roller 7, a first support seat 8, a main guide rod 9, a bidirectional lead screw 10, a support 11, a support shaft 12, a rotation damper 13, a support cone 14, a first support frame 15, a second support frame 16, a first electric push rod 17, an upper cone plate 18, an upper auxiliary pressure roller 19, a second electric push rod 20, a second lifting seat 21, a lower cone plate 22, a third electric push rod 23, a support platform 24, a cutter 25, a third clamping plate 26, and a lower auxiliary pressure roller 27. The right side of the base 101 is rotatably connected to multiple horizontal right rollers 7 in the front-to-back direction. All right rollers 7 are on the same horizontal plane, ensuring stable transport of the lithium battery pack. Two mirror-image support seats 8 are fixed to the right side of the base 101. A horizontal main guide rod 9 is fixed to the upper part of both support seats 8. A horizontal bidirectional lead screw 10 is rotatably connected to the upper part of both support seats 8. Supports 11 are slidably connected to the front and rear ends of the main guide rod 9. Horizontal support shafts 12 are rotatably connected to the left sides of both supports 11. The two support shafts 12 are coaxial. A rotation damper 13 is installed between the support shafts 12 and the supports 11. The rotation damper 13 increases the rotational resistance of the support shafts 12. The resistance allows the blue film roll to indirectly reduce its rotational speed using the rotational damper 13 when rotating with the support shaft 12, preventing excessive release of the blue film roll due to inertia. Support cones 14 are coaxially fixed to adjacent ends of the two support shafts 12. A vertical first support frame 15 is fixed to the upper right part of the base 101, and a vertical second support frame 16 is fixed to the lower right part of the base 101. A vertical first electric push rod 17 is fixed to the top of the first support frame 15. An upper conical plate 18 is fixed to the bottom end of the push rod 17. The left end face of the upper conical plate 18 is vertical, and the right end is inclined downwards to the left. The left and right end faces of the upper conical plate 18 have a smooth transition at the bottom, allowing for a more gentle movement. To prevent damage to the blue film due to sharp edges, a horizontal upper auxiliary pressure roller 19 is rotatably connected to the upper left part of the upper conical plate 18 in the front-back direction. A vertical second electric push rod 20 is fixed to the bottom end of the second support frame 16. A second lifting seat 21 is fixed to the top of the push rod of the second electric push rod 20. A lower conical plate 22 is fixed to the right side of the second lifting seat 21. A horizontal third electric push rod 23 is fixed to the right end of the lower conical plate 22 in the left-right direction. The upper left end face of the lower conical plate 22 is inclined to match the right end face of the upper conical plate 18. This structure allows the blue film to easily adhere to the upper left end face of the lower conical plate 22 when the upper conical plate 18 presses down on it. A horizontal support platform 24 is fixed to the upper middle part of the left end of the lower conical plate 22 in the front-back direction.A strip-shaped cutter 25 is fixed to the top of the support platform 24 in the front-to-back direction. A vertical clamping plate 26 is fixed to the left end of the push rod of the third electric push rod 23. The upper right end face of the clamping plate 26 is inclined to match the upper left end face of the lower cone plate 22. A horizontal lower auxiliary pressure roller 27 is rotatably connected to the upper left part of the clamping plate 26 in the front-to-back direction. The distance between the leftmost edge of the outer circumferential wall of the lower auxiliary pressure roller 27 and the leftmost edge of the outer circumferential wall of the upper auxiliary pressure roller 19 is the thickness of the blue film. The leftmost edge of the outer circumferential wall of the lower auxiliary pressure roller 27 is located to the left of the leftmost edge of the outer circumferential wall of the upper auxiliary pressure roller 19, thus facilitating the upper auxiliary pressure roller 19 to roll the two layers of blue film on the right end face of the lithium battery pack. The clamping plate 25... The top surface of the 26-inch plate smoothly transitions to the left and right end surfaces, thereby reducing damage to the blue film when it comes into contact with this area. The transfer mechanism 3 includes a main servo motor 28, a mounting base 29, an upper pressure roller 30, a lower pressure roller 31, a top block 32, a main guide block 33, a receiving groove 34, a fourth electric push rod 35, and a fourth clamping plate 36. A vertical main servo motor 28 with a braking function is fixed in the middle of the base 101. A horizontal mounting base 29 is fixed at the top of the shaft of the main servo motor 28. A set of multiple upper pressure rollers 30 is rotatably connected to the upper part of the mounting base 29, and a set of multiple lower pressure rollers 31 is rotatably connected to the bottom of the mounting base 29. A [missing information - likely a device or structure] is placed between the upper pressure rollers 30 and the lower pressure rollers 31. A horizontal top block 32, which is rectangular in shape, is provided. All upper pressure rollers 30 are positioned on the same horizontal plane and arranged along the front-to-back direction. All lower pressure rollers 31 are positioned on the same horizontal plane and arranged along the front-to-back direction. The highest point of the outer circumferential wall of the lower pressure roller 31 is at the same height as the highest point of the outer circumferential wall of the right support roller 7, thus ensuring stable transport of the lithium battery pack. Horizontal guide blocks 33 are fixed at both ends of the inner wall of the mounting base 29. Both guide blocks 33 have arrow-shaped sections on their left and right sides. The arrow-shaped structure allows the blue film to be pushed from the center upwards and downwards, facilitating its full expansion and adhesion to the lithium battery pack. The guide blocks 33 are located between the upper pressure rollers 30 and the lower pressure rollers 31. The top block 32 rolls and rubs against the upper pressure roller 30 and the lower pressure roller 31 at its upper and lower ends, respectively. The front and rear ends of the top block 32 contact and adhere to the adjacent ends of the two main guide blocks 33. It should be ensured that the width and height of the top block 32 are consistent with the width and height of the lithium battery pack after only one layer of blue film is applied, thereby ensuring that the lithium battery pack can be tightly pressed and adhered by the upper pressure roller 30, the lower pressure roller 31, and the main guide blocks 33 after being covered with a layer of blue film. Horizontal receiving grooves 34 extend through the middle of each of the two main guide blocks 33. Horizontal No. 4 electric push rods 35 are fixed at both ends of the mounting base 29, and horizontal No. 4 clamping plates 36 are fixed to the ends of the push rods of the two No. 4 electric push rods 35, respectively.

[0025] The application mechanism 4 includes a No. 5 electric push rod 37, a No. 5 lifting seat 38, a No. 6 electric push rod 39, an upper pressure plate 40, a side pressure plate 41, a No. 7 electric push rod 42, a No. 7 lifting seat 43, a left support roller 44, and a secondary guide block 45. A vertical No. 5 electric push rod 37 is fixed to the top left of the base 101. A No. 5 lifting seat 38 is fixed to the bottom of the push rod of the No. 5 electric push rod 37. Vertical No. 6 electric push rods 39 are fixed to the left and right sides of the top of the No. 5 lifting seat 38. A horizontal upper pressure plate 40 is fixed to the bottom of the push rod of the No. 6 electric push rod 39. Vertical side pressure plates 41 are fixed to the front and rear ends of the left inner wall of the base 101. A vertical No. 7 electric push rod 42 is fixed to the lower left of the base 101. A horizontal No. 7 lifting seat 43 is fixed to the top of the push rod of the No. 7 electric push rod 42. A set of multiple left rollers 44 rotate on the upper part of the lowering seat 43. The left rollers 44 are all located in the same horizontal plane in the front-back direction. Horizontal secondary guide blocks 45 are fixed at both ends of the left inner wall of the base 101. The right part of the secondary guide block 45 is arrow-shaped. The two secondary guide blocks 45 are at the same height as the two main guide blocks 33. The height of the secondary guide blocks 45 and the main guide blocks 33 should be slightly less than the height of the lithium battery pack. This will prevent the excess blue film at the top and bottom of the battery pack from sticking to the secondary guide blocks 45 and the main guide blocks 33 when it tends to be horizontal due to its own stiffness. The distance between the two secondary guide blocks 45 should be close to the sum of the width of the lithium battery pack and the thickness of the four layers of blue film. This will allow the two secondary guide blocks 45 to press the lithium battery pack tightly against the front and rear ends after each of the two layers of blue film is covered.

[0026] The pushing mechanism 1 includes an eighth electric push rod 46, a push plate 47, a ninth electric push rod 48, a right moving seat 49, and guide rollers 50. The right end of the base 101 is fixed with a horizontal eighth electric push rod 46, the left end of the push rod of the eighth electric push rod 46 is fixed with a horizontal push plate 47, the opposite ends of the two first support seats 8 are respectively fixed with horizontal ninth electric push rods 48, the push rod ends of the two ninth electric push rods 48 are respectively fixed with horizontal right moving seats 49, and the two right moving seats 49 are respectively rotatably connected to a group of multiple guide rollers 50. The two groups of guide rollers 50 are vertical and located in two positive planes.

[0027] The correction mechanism includes a No. 10 electric push rod 51, a left moving seat 52, a secondary servo motor 53, and rollers 54. The base 101 has a horizontal No. 10 electric push rod 51 fixed at both the front and rear ends of the left side. The push rod end of the No. 10 electric push rod 51 is fixed with a left moving seat 52. The top ends of the two left moving seats 52 are respectively fixed with multiple vertical secondary servo motors 53 with braking function. The two left moving seats 52 are rotatably connected to a set of multiple rollers 54. The two sets of rollers 54 are respectively located in two positive planes. The rollers 54 are coaxially fixed with the rotation axis of the secondary servo motor 53.

[0028] Two adjacent ends of the four clamping plates 36 are respectively fixed with sponge pads 55. The sponge pads 55 are used to fully contact the front and rear ends of the lithium battery pack to enhance friction and prevent the lithium battery pack from loosening in the left and right direction when clamped by the four clamping plates 36 and sponge pads 55. The four clamping plates 36 and sponge pads 55 can be accommodated in the receiving groove 34, so that when the four clamping plates 36 and sponge pads 55 are accommodated in the receiving groove 34, they will not obstruct the passage of the lithium battery pack between the two main guide blocks 33. The left moving seat 52 rotates on its left side. A vertical application roller 56 is connected. Vertical auxiliary light rods 57 are fixed to the top of the upper conical plate 18 and the bottom of the seventh lifting seat 43, respectively. The auxiliary light rod 57 at the top of the upper conical plate 18 is slidably connected to the first support frame 15, and the auxiliary light rod 57 at the bottom of the seventh lifting seat 43 is slidably connected to the base 101. The auxiliary light rods 57 enable the upper conical plate 18 and the seventh lifting seat 43 to move up and down more smoothly. A handwheel 58 is coaxially fixed in the middle of the bidirectional lead screw 10, which facilitates the rotation of the bidirectional lead screw 10.

[0029] The controller 5 is electrically connected to the following electric actuators: No. 1 electric actuator 17, No. 2 electric actuator 20, No. 3 electric actuator 23, main servo motor 28, No. 4 electric actuator 35, No. 5 electric actuator 37, No. 6 electric actuator 39, No. 7 electric actuator 42, No. 8 electric actuator 46, No. 9 electric actuator 48, No. 10 electric actuator 51, and auxiliary servo motor 53. The controller 5 is powered by an external power source. When the No. 1 electric actuator 17 is energized, it can extend and retract, causing the upper cone plate 18 to move up and down. When the No. 2 electric actuator 20 is energized, it can extend and retract, causing the No. 2 lifting seat 21 to move up and down. When the upper cone plate 18 and the lower cone plate 22 are close to a certain position, the smooth transition at the bottom of the upper cone plate 18 can contact the top of the cutter 25. When the smooth transition at the bottom of the upper cone plate 18 contacts the top of the cutter 25, there is a small gap between the right end face of the upper cone plate 18 and the upper left end face of the lower cone plate 22. The spacing between the blue film thicknesses allows the upper cone plate 18 and lower cone plate 22 to clamp the blue film effectively. When the third electric push rod 23 is energized and retracts, it can move the third clamping plate 26 left and right.

[0030] Working principle of the invention:

[0031] First, when using the product, clamp the blue film roll between the two support cones 14. Specifically, select a blue film roll of appropriate width (ensuring that after winding the blue film roll around the lithium battery pack on the top, bottom, left, and right sides, there is excess material in both the front and back sections, and the width of the excess material should be close to but not greater than the height of the lithium battery pack). Based on the width of the blue film roll, rotate the bidirectional lead screw 10 appropriately to move the two support cones 14 away from each other. Then, place the blue film roll between the two support cones 14, and rotate the bidirectional lead screw 10 again to clamp the roll between the two support cones 14. Due to the conical structure of the support cones 14… The system automatically ensures that the roll material is coaxial with the support cone 14 and the support shaft 12, while ensuring that the adhesive side of the blue film is to the right. Then, the blue film is partially unfolded and the unfolded end is adhered to the upper left end face of the lower cone plate 22. Then, by controlling the retraction of the third electric push rod 23, the third clamping plate 26 clamps the adhered part of the blue film. At this time, by controlling the appropriate retraction of the first electric push rod 17 and the second electric push rod 20, the bottom of the upper cone plate 18 is higher than the upper pressure roller 30, and the top surface of the lower cone plate 22 and the top surface of the third clamping plate 26 are much lower than the lower pressure roller 31 (for ease of description, these two states are referred to as state b). Next, the stage of applying blue film to the upper, lower, left and right end faces of the lithium battery pack can be entered.

[0032] Subsequently, the lithium battery pack to be coated is placed on each of the right rollers 7. At this time, the top block 32 is located on the right side of the mounting base 29, and the fourth clamping plate 36 and the sponge pad 55 are completely within the receiving groove 34. Then, the two ninth electric push rods 48 are extended, so that the guide roller 50 contacts the front and rear end faces of the lithium battery pack and calibrates the position of the battery pack, so that the front and rear positions of the symmetry center of the battery pack are consistent with the position of the symmetry center of the top block 32. Then, the eighth electric push rod 46 is extended, so that the push plate 47 pushes the lithium battery pack to the left, so that the left end face of the lithium battery pack first applies the blue film. As the lithium battery pack continues to move to the left, the left end of the lithium battery pack and the right end of the top block 32 will be applied to the left end of the lithium battery pack. The blue film on the end face is squeezed, and then the lithium battery pack pushes the top block 32 to move to the left, so that the top block 32 moves to the left side of the mounting base 29. During the leftward movement of the lithium battery pack, the second electric push rod 20 gradually extends, and the lithium battery pack pulls the blue film into the space between the upper pressure roller 30 and the lower pressure roller 31. During this period, under the pulling action of the lithium battery, the blue film roll continues to slowly unfold. As the lithium battery pack pulls the blue film into the space between the upper pressure roller 30 and the lower pressure roller 31, multiple upper pressure rollers 30 and lower pressure rollers 31 will jointly roll and press the blue film corresponding to the top and bottom ends of the lithium battery pack, so that the blue film is well attached to the top and bottom ends of the lithium battery pack. When the eighth electric push rod 46 stops moving, the right end face of the lithium battery pack is located outside the lower auxiliary pressure roller 27. The distance between the leftmost left side of the circumferential wall and the right end face of the lithium battery pack and the leftmost left side of the outer circumferential wall of the lower auxiliary pressure roller 27 is the thickness of the blue film. During this process, the lithium battery pack will pass through the right end of the main guide block 33, so that the right end of the main guide block 33 will squeeze and apply the excess blue film at the front and rear ends of the left side of the lithium battery pack to the right. When the eighth electric push rod 46 stops moving, the second electric push rod 20 stops moving at the same time. Then, the fourth electric push rod 35 is controlled to extend the push rod, so that the fourth clamping plate 36 and the sponge pad 55 clamp the front and rear ends of the lithium battery pack. Then, the eighth electric push rod 46 is controlled to retract the push rod to reset. Then, the second electric push rod 20 and the third electric push rod 23 are controlled to extend the push rod, so as to release the third clamping plate 26 from the adhesive on the lower cone plate. The blue film at the upper left end of plate 22 is clamped, and as the lower cone plate 22 moves upward, the blue film is gradually pulled and peeled off from the lower cone plate 22, so that it can be rolled upward by the lower auxiliary pressure roller 27. This makes this part of the blue film adhere to the right end face of the lithium battery pack without any residue (the reason for no residue is that the length of the blue film unrolled from the roll is calculated in advance, that is, the length of the blue film below the lithium battery when the left end face of the lithium battery pack is adhered to the blue film is calculated and limited in advance. This length is limited by controlling the second electric push rod 20 to retract the push rod appropriately after the third clamping plate 26 and the lower cone plate 22 clamp the blue film, which can release the corresponding length of blue film). Then, control the second electric push rod 20 to retract the push rod appropriately and stop. Then, control the first electric push rod 17 to extend the push rod appropriately and stop.Until the upper conical plate 18 is inserted between the third clamping plate 26 and the lower conical plate 22, and the smooth transition at the bottom end of the upper conical plate 18, together with the cutter 25, squeezes the blue film, thereby cutting the blue film. At the same time, the upper conical plate 18 squeezes the blue film, causing the cut end of the blue film roll to adhere to the upper left end face of the lower conical plate 22. Then, the second electric push rod 20 continues to retract, while the first electric push rod 17 continues to extend. Throughout the process, the upper conical plate 18 and the lower conical plate 22 maintain a tight clamping of the blue film. Simultaneously, the cut blue film belonging to the lithium battery pack will be pressed by the upper and lower clamping plates. Roller 19 rolls the film until there is no remaining blue film on the right side of the lithium battery pack. (The reason for no remaining film is that the length of the blue film belonging to the lithium battery pack that is cut is calculated and limited in advance. This length is the straight-line distance from the bottom of the upper cone plate 18 to the upper right part of the lithium battery pack when the upper cone plate 18 and the cutter 25 are cutting the blue film. This distance is determined by controlling the extension and retraction of the second electric push rod 20 and the third electric push rod 23.) This completes the application of the blue film to the top, bottom, left, and right sides of the lithium battery pack, as well as to the front and rear ends of the left side of the lithium battery pack (for ease of description, this is referred to as...). (In state c), then the first electric push rod 17 retracts, and the third electric push rod 23 retracts, causing the third clamping plate 26 to clamp the blue film of the adhesive part until state b is reached. At this time, the length of the blue film roll is also limited. At this time, the excess of the blue film on the right side of the lithium battery pack on both the front and rear sides does not contact the right end of the main guide block 33. Then, the main servo motor 28 is controlled to rotate 180 degrees forward and then brake, so that the left and right parts of the mounting base 29 are "swapped". After completion, the top block 32 is in the "new right part" of the mounting base 29, and the "new left part" of the mounting base 29 is in the "new left part". The lithium battery pack is ready for the next stage—applying blue film to the front and rear faces. The empty space in the "new right" part of the mounting base 29 can then be used again for applying blue film to the top, bottom, left, and right faces of the lithium battery pack, following the process described above. When a lithium battery pack enters the "new right" part of the mounting base 29, the new lithium battery pack pushes the top block 32 to the left, causing the top block 32 to push the lithium battery pack in state c to the left, discharging it from the mounting base 29 and moving it to the top of the left idler roller 44, thus entering the stage of applying blue film to the front and rear faces of the lithium battery pack.

[0033] During the application of the blue film to the front and rear faces of the lithium battery pack: to ensure that the left roller 44 can properly support the lithium battery pack in state C and reduce bumps, the seventh electric push rod 42 should be extended appropriately beforehand so that the highest point of the outer circumference of the left roller 44 is flush with the bottom face of the lithium battery pack in state C (for ease of description, this state is referred to as state G). When the lithium battery pack in state C is pushed by the top block 32 and moves above the left roller 44, the tenth electric push rod 51 is extended so that the roller 54 clamps the front and rear ends of the lithium battery pack in state C and corrects the front and rear position of the lithium battery pack in state C relative to the base 101. During this process, the auxiliary servo motor 53 is simultaneously rotated appropriately and then braked to ensure proper positioning. The lithium battery pack in state c is dragged to the left until it moves directly below the upper pressure plate 40. As the lithium battery pack in state c is pushed by the top block 32 and moves above the left idler roller 44, the "new left part (formerly right part)" of the lithium battery pack in state c inevitably passes between the two guide blocks 45. This allows the excess blue film of the "new left part (formerly right part)" of the lithium battery pack in state c to be squeezed to the right, causing the excess blue film to adhere to both ends of the lithium battery pack (for ease of description, this state is referred to as state d). Then, the push rod of the tenth electric push rod 51 is retracted, and the push rod of the fifth electric push rod 37 is extended appropriately, causing the fifth lifting seat 38 to move downwards. This allows the fifth lifting seat to... The inner wall of section 38 bends and presses the excess blue film at the top of the lithium battery pack in state d downwards, causing this portion of the blue film to adhere to the front and rear ends of the lithium battery pack (for ease of description, this state is referred to as state e). Then, it controls electric push rod 39 to extend until the upper pressure plate 40 contacts the top of the lithium battery pack in state e. Next, it controls electric push rod 39 to extend further while simultaneously controlling electric push rod 42 to retract, thus maintaining pressure on the lithium battery pack in state e by the upper pressure plate 40 and causing the lithium battery pack in state e to move downwards between the two side pressure plates 41. This allows pressure to be applied to the excess blue film at the bottom of the lithium battery, causing it to adhere to the blue film surface at the front and rear ends of the lithium battery pack (at this point, the blue film...). The film has completely covered the lithium battery pack (this state is referred to as state f). Then, electric push rod 39 retracts and resets, followed by electric push rod 37 retracting and resetting. Electric push rod 42 extends until the lower pressure roller 31 reaches state g. At this point, electric push rod 39 extends, causing roller 54 to clamp the front and rear ends of the lithium battery pack in state f again. Then, auxiliary servo motor 53 rotates appropriately and then brakes, dragging the lithium battery pack in state f to the left until it detaches from the left support roller 44. During this detachment, the two application rollers 56 roll over the front and rear ends of the lithium battery pack in state f.This allows the blue film to fully adhere to both the front and back ends of the lithium battery pack.

[0034] This completes the film wrapping of the lithium battery pack.
