[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, and bottom", generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, and "inner and outer" refer to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first, second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0033] The present disclosure provides a battery assembly system for assembling batteries, wherein the battery comprises a separate shell 1 and a pole core 2, wherein the shell 1 has an entrance and a chamber for accommodating the pole core 2, and the battery assembly system comprises: a positioning mechanism 8, which is used to fix the shell 1 and direct the entrance toward the pole core 2; a conveying mechanism 3, which is arranged on one side of the positioning mechanism 8 and is used to drive the pole core 2 to move toward the shell 1 so that the pole core 2 enters the chamber through the entrance; and a folding mechanism 4, which is arranged between the shell 1 and the pole core 2, wherein an insulating film 21 is attached to the upper and lower surfaces of the pole core 2, and the insulating film 21 extends out of the pole core 2 along two sides that are horizontally and vertically to the moving direction of the pole core 2, and the folding mechanism 4 folds the portion of the insulating film 21 extending out of the pole core 2 and attaches it to the side of the pole core 2 so that the insulating film 21 wraps the pole core 2 circumferentially.

[0034] Through the above technical scheme, the shell 1 is fixed on the positioning mechanism 8 and the entrance is facing the pole core 2. The conveying mechanism 3 drives the pole core 2 to move toward the shell 1 so that the pole core 2 enters the shell 1. Before the pole core 2 enters the shell 1, the insulating film 21 attached to the upper and lower surfaces of the pole core 2 is folded by the folding mechanism 4 so that the insulating film 21 is wrapped circumferentially around the outer side of the pole core 2 to insulate the pole core 2 from the shell 1. In this way, the insulating film 21 is folded while the pole core 2 enters the shell, thereby improving the assembly efficiency of the battery assembly.

[0035] As an optional implementation, Figure 1-5As shown, the folding mechanism 4 includes two sets of folding guide devices 41 relatively arranged on both sides of the moving path of the pole core 2, corresponding to the insulating film 21 extending from both sides of the pole core 2 respectively, and the folding guide device 41 is provided with a guide groove 44 for the pole core 2 to be inserted, so that the insulating film 21 extending out of the pole core 2 during the movement of the pole core 2 is folded inward from a horizontal state to a vertical state along the guide groove 44. By arranging the folding guide devices 41 on both sides of the moving path of the pole core 2, the part of the insulating film 21 extending out of the pole core 2 is brought into contact with the guide groove 44 during the movement of the pole core 2, so that the insulating film 21 is folded.

[0036] Among them, Figure 2 As shown, the folding guide device 41 includes an upper folding guide plate 42, a lower folding guide plate 45 and a guide member 43. The upper folding guide plate 42 is spaced above the lower folding guide plate 45 by the guide member 43 to form a guide groove 44 between the upper folding guide plate 42 and the lower folding guide plate 45. The pole core 2 is inserted into the guide groove 44 to guide the pole core 2 while allowing the insulating film 21 extending out of the pole core 2 to contact the guide member 43, thereby folding inward from a horizontal state to a vertical state.

[0037] Alternatively, if Figure 3-4As shown, the guide member 43 includes an upper guide block 432 arranged at the bottom of the upper folding guide plate 42 and a lower guide block 431 arranged at the top of the lower folding guide plate 45. The bottom surface of the upper folding guide plate 42 close to the pole core 2 is configured as a first plane 421. One end of the upper guide block 432 is connected to the first plane 421, and the other end extends toward the direction of the housing 1 and is inclined inwardly from the outer edge of the upper folding guide plate 42, and the inner side surface of the end is configured as a first vertical surface 4321. The first plane 421 and the first vertical surface 4321 are connected by the first plane 421. 1 is connected to a first curved surface 4322 formed by twisting the lower folding guide plate 45 toward the first vertical surface 4321; the top surface of one end of the lower folding guide plate 45 close to the pole core 2 is configured as a second plane 451, one end of the lower guide block 431 is connected to the second plane 451, and the other end extends toward the direction of the shell 1 and is inclined inwardly from the outer edge of the lower folding guide plate 45, and the inner side surface of the end is configured as a second vertical surface 4311, and the second plane 451 and the second vertical surface 4311 are connected by a second curved surface 4312 formed by twisting the second plane 451 toward the second vertical surface 4311. When the material is incoming, the insulating film 21 attached to the upper side of the pole core 2 contacts the first plane 421. As the pole core 2 moves, the insulating film 21 contacts the first curved surface 4322, and gradually folds inward from a horizontal state along the first curved surface 4322 until it contacts the first vertical surface 4321 and is formed into a vertical state, completing the folding; the insulating film 21 attached to the lower side of the pole core 2 contacts the second plane 451. As the pole core 2 moves, the insulating film 21 contacts the second curved surface 4312, and gradually folds inward from a horizontal state along the second curved surface 4312 until it contacts the second vertical surface 4311 and is formed into a vertical state, completing the folding.

[0038] As an optional implementation, Figure 1 As shown, the battery assembly system also includes an upper pressing roller 5 and a lower pressing roller 6, which are arranged at intervals in the upper and lower parts to press the upper surface and the lower surface of the pole core 2 respectively, and the upper pressing roller 5 and the lower pressing roller 6 are arranged at the folding mechanism 4 to prevent the insulating film 21 from warping during the folding process. For example, an installation notch can be provided on the side of the upper folding guide plate 42 and the lower folding guide plate 45 close to the shell 1, and the upper pressing roller 5 and the lower pressing roller 6 are respectively installed on the upper folding guide plate 42 and the lower folding guide plate 45. When the insulating film 21 is folded, the insulating film 21 attached to the upper and lower sides of the pole core 2 will inevitably warp up under the thrust of the conveying mechanism 3 and the resistance of the guide member 43. At this time, the insulating film 21 is pressed by the upper pressing roller 5 and the lower pressing roller 6 to prevent the insulating film 21 from warping up.

[0039] As an optional implementation, Figure 1 and Figure 6As shown, the battery assembly system also includes a guide mechanism 7, which is arranged at the exit of the folding mechanism 4 and can move toward and away from the shell 1. For example, the guide mechanism 7 can be driven to move by an electric telescopic rod, a telescopic cylinder, a motor and other devices. As long as the purpose of the present disclosure can be achieved, it is not limited here, so that the pole core 2 is inserted at the entrance when entering the chamber to prevent the shell 1 from scratching the insulating film 21. The pole core 2 moves along the guide mechanism 7 to prevent the pole core 2 from deviating from the contact with the shell 1, causing the insulating film 21 to be scratched and damaged or warped by the shell 1, and the pole core 2 is separated from the shell 1 after entering the chamber to assemble the next battery.

[0040] Alternatively, if Figure 6 As shown, the guide mechanism 7 includes a guide cavity 71, a spring 73 and a pressure block 72. The guide cavity 71 has a through hole 711 for the pole core 2 to pass through. The spring 73 is arranged on the outer wall around the guide cavity 71 through the pressure block 72 and extends out of the guide cavity 71 at one end close to the shell 1. The side wall of the guide cavity 71 gradually shrinks from one end close to the pole core 2 to one end close to the shell 1 so that the spring 73 contacts the pole core 2. Before the pole core 2 enters the shell, the guide mechanism 7 moves toward the shell 1 to insert the spring 73 into the entrance of the shell 1. Since the spring 73 is thin and is only inserted a small distance, it will not affect the pole core 2 from entering the shell 1. In this way, the outer side of the pole core 2 contacts the spring 73 after entering the guide cavity 71. The spring 73 fits the outer surface of the pole core 2 so that there is a gap between the pole core 2 and the shell 1 to prevent the pole core 2 from contacting the shell 1.

[0041] As an optional implementation, Figure 1 As shown, the conveying mechanism 3 includes a guide rail 31 extending along the moving direction of the pole core 2, a push block 32 slidably connected to the guide rail 31, a driving device 34 for driving the push block 32 to move, and a placement plate 33. The pole core 2 is placed on the placement plate 33, and the push block 32 is pressed against the end of the pole core 2 away from the shell 1. The placement plate 33 is provided with a through groove for the push block 32 to pass through. When in use, the guide rail 31 is arranged below the placement plate 33, and the push block 32 can pass through the placement plate 33 along the through groove. The through groove extends along the length direction of the placement plate 33 to prevent the placement plate 33 from blocking the push block 32 and making the push block 32 unable to move. The driving device 34 drives the push block 32 to move along the guide rail 31, and the push block 32 pushes the pole core 2 to move toward the shell 1. For example, the driving device 34 can be a movable telescopic rod, a telescopic cylinder, a motor or other devices, as long as the purpose of the present disclosure can be achieved, it is not limited here. In other embodiments, the guide rail 31 may not be provided, and a telescopic cylinder extending in the same direction as the placement plate 33 may be directly provided, and the push block 32 may be installed on the telescopic end of the telescopic cylinder, and the push block 32 may be moved by the telescopic end.

[0042] As an optional implementation, Figure 1As shown, two limiting bars 35 are arranged opposite to each other and extend in the same direction as the guide rail 31 on the placement plate 33. The pole core 2 is placed between the two limiting bars 35 to guide and limit the pole core 2, thereby preventing the pole core 2 from deviating during movement.

[0043] As an optional implementation, Figure 1 As shown, the positioning mechanism 8 includes a positioning plate 81 and clamping devices 82 arranged on the positioning plate 81 and located on both sides of the shell 1. The shell 1 is placed on the positioning plate 81 and clamped and fixed by the clamping devices 82 on both sides. The clamping device 82 can be a telescopic cylinder or an electric telescopic rod that can be extended toward the shell 1.

[0044] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0046] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
