Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly, in particular to a battery module assembly system for new energy vehicles. Background Art

[0002] The battery module assembly system for new energy vehicles is a comprehensive system integrating battery cell selection, combination, testing, protection circuit design, etc. The system aims to combine single cells that meet the specifications and performance requirements into modules through precise operations, and ensure the safety and consistency of the battery modules through strict testing. The main links of the assembly system include: selection of battery cells, combination of battery cells, assembly of battery packs, testing of battery packs, and design of protection circuits.

[0003] Before the combination of battery cells (electric cores), it is usually necessary to clean the battery cells. On the one hand, it is to remove the dust attached to both sides of the electrodes during the production and transportation of the battery cells. On the other hand, it is to enhance the welding strength between both sides of the electrodes and the nickel sheets. Currently, in the battery module assembly system for new energy vehicles, a plasma cleaner is usually used to clean both sides of the battery cells. This cleaning equipment has a high degree of automation and high speed, and is widely used in the assembly system. However, when cleaning both sides of the battery cells through two plasma cleaners, since the distance between adjacent two battery cells is relatively close and a single electric core cannot rotate, a large flow of compressed air needs to be introduced to take away the excited pollutants during cleaning, which increases the number of equipment accessories and energy consumption in the assembly system. For this reason, a battery module assembly system for new energy vehicles. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figures 1 - 5, a new energy vehicle battery module assembly system, including a battery module assembly production line 1. There is a battery cell cleaning mechanism 2 for cleaning the battery cells on the battery module assembly production line 1. The battery cell cleaning mechanism 2 is composed of a transfer member 201, an X-axis movement module, a Z-axis movement module, and a plasma cleaner 202. The X-axis movement module and the Z-axis movement module can respectively drive the transfer member 201 to move on the X-axis and the Z-axis, thereby realizing the transfer and cleaning of the battery cells (this technology is an existing technology and will not be elaborated here);

[0029] There is a rotating assembly 3 on the battery module assembly production line 1 for driving the transfer member 201 to rotate and clean the battery cells on it;

[0030] The rotating assembly 3 includes a mounting plate 301. Under the mounting plate 301, there is a connecting shell 302 used in cooperation with the transfer member 201. Inside the connecting shell 302, multiple rotating rollers 303 for driving the battery cells to rotate are rotatably arranged. Inside the mounting plate 301, there is a moving assembly for driving the connecting shell 302 to move along with the transfer member 201. Inside the connecting shell 302, there is a driving assembly for driving the rotating rollers 303 to rotate.

[0031] Most of the cleaning of traditional battery cells is that the transfer member 201 transfers the battery cells on the battery module assembly production line 1 between two plasma cleaners 202, and the two sides of the electrodes of the battery cells are cleaned by the plasma cleaners 202. The plasma cleaners 202 emit plasma with high reactivity or high energy, which will react with organic pollutants and particulate pollutants and collide to form various volatile substances. When the battery cells are horizontally fixed, the volatile substances generated at the electrode positions of the battery cells will move in two directions, upward and downward of the battery cells. If the compressed air for cleaning is sprayed from bottom to top, the volatile substances above the battery cells will immediately be carried away by the compressed air, and when the volatile substances moving downward of the battery cells are impacted by the compressed air, they may be adsorbed on one side or the electrode of the battery cells. To solve this situation, it is necessary to increase the input speed and input amount of the compressed air, which will lead to a relatively high energy consumption of the entire battery module assembly system. Therefore, a rotating assembly 3 used in cooperation with the battery cell cleaning mechanism 2 is provided. Through the rotating assembly 3, the four battery cells on the transfer member 201 can be rotated, that is, the battery cells generate self-rotation. When the rotating battery cells are cleaned by the two plasma cleaners 202, the volatile substances generated at the electrode positions of the battery cells will rotate and move to the outside. When the battery cells rotate one week, for the volatile substances generated at the electrode positions of the battery cells, the volatile substances rotating one week will all diffuse above the battery cells and thus be carried away by the compressed air. In this case, it is not necessary to increase the input amount and input rate of the compressed air for cleaning, greatly reducing the cleaning energy consumption.

[0032] Embodiment Two

[0033] Please refer to Figures 3 - 4, This embodiment is basically the same as Embodiment 1. This embodiment is based on Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, reference can be made to each other, and details will not be elaborated here.

[0034] As a preferred technical solution of this embodiment, the driving assembly includes a driving motor 304 arranged in the connecting shell 302. A driving gear 305 is provided at the output end of the driving motor 304. A driven gear 306 is provided on the rotating roller 303. Two transmission gears 307 are rotatably arranged on the inner wall of the connecting shell 302, and the transmission gears 307 are respectively meshed with two adjacent driven gears 306. The driving gear 305 is meshed with the two middle driven gears 306 in the connecting shell 302;

[0035] Furthermore, two exhaust shells 311 are provided on the connecting shell 302. An exhaust pipe is communicated with the exhaust shell 311. The lower end surface of the exhaust shell 311 is arranged in a wavy shape. Through the provided exhaust shell 311, the pollutants generated at the electrode of the battery cell can be effectively adsorbed and taken away.

[0036] Furthermore, arc grooves for placing the battery cells are respectively provided on the transfer member 201 and the connecting shell 302; an arc-shaped opening for cooperating with the rotating roller 303 is provided on the connecting shell 302. An anti-slip washer is sleeved on the rotating roller 303 to increase the friction force, so that the battery cell can rotate better.

[0037] The function of the driving assembly in the present utility model is to drive the four battery cells between the connecting shell 302 and the transfer member 201 to rotate, so that the volatile substances generated at the electrodes of the battery cells can all rotate above the battery cells and be taken away by compressed air, reducing the situation that the volatile substances reattach to the battery cell body. In this case, it is possible to easily discharge the volatile substances after plasma cleaning without introducing a large flow of compressed air;

[0038] The working principle of the driving assembly is specifically as follows: When the driving motor 304 works, it drives the driving gear 305 to rotate. After the driving gear 305 rotates, it can drive the two middle driven gears 306 to rotate. The two middle driven gears 306 and the two outer driven gears 306 are driven by two transmission gears 307. Therefore, when the two middle driven gears 306 in the connecting shell 302 are driven to rotate, the two driven gears 306 on both sides in the connecting shell 302 can be driven to rotate through the two transmission gears 307, and finally the four driven gears 306 rotate, that is, drive the four rotating rollers 303 to rotate.

[0039] Since the connecting shell 302 and the transfer member 201 can be in contact, when the four rotating rollers 303 rotate, the four battery cells between the connecting shell 302 and the transfer member 201 can be driven to rotate.

[0040] Embodiment 3

[0041] Please refer to Figure 2 and Figure 5 , this embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. For the same parts, reference can be made to each other, and details will not be elaborated here.

[0042] As a preferred technical solution of this embodiment, the moving component includes a T-shaped sliding block 308 slidably arranged in the mounting plate 301. The lower end of the T-shaped sliding block 308 is fixedly connected to the connecting shell 302. A servo motor 309 is provided on the mounting plate 301. A lead screw 310 is provided at the output end of the servo motor 309 in the mounting plate 301. The T-shaped sliding block 308 is provided with an internal thread through hole for cooperating with the lead screw 310.

[0043] The mounting plate 301 is fixedly arranged with the battery module assembly production line 1 through a plurality of connecting columns.

[0044] The function of the moving component in the present utility model is to drive the connecting shell 302 to move along with the transfer member 201. When the transfer member 201 drives the battery cell for cleaning, first, the battery cell on the battery module assembly production line 1 is placed on the transfer member 201. Then, the transfer member 201 rises to the set plane of the ion cleaner 202. Further, the transfer member 201 moves horizontally and slowly transfers the battery cell between the two ion cleaners 202 for cleaning. Finally, the cleaned battery cell is placed into the battery module assembly production line 1 for the next processing step. When the transfer member 201 rises to the limit position, the upper end surface of the transfer member 201 abuts against the lower end surface of the connecting shell 302. Then, when the transfer member 201 moves along the X-axis, the entire connecting shell 302 will also move along with the transfer member 201 under the drive of the moving component. After the cleaning is completed, the moving component resets, and then the above steps are repeated;

[0045] The specific principle of the moving component is as follows: After the upper end surface of the transfer member 201 abuts against the lower end surface of the connecting shell 302, the transfer member 201 moves, and the servo motor 309 is started to drive the lead screw 310 to rotate. After the lead screw 310 rotates, it can drive the T-shaped sliding block 308 to move in the mounting plate 301. Since the lower end of the T-shaped sliding block 308 is fixedly connected to the connecting shell 302, when the T-shaped sliding block 308 moves, it can drive the connecting shell 302 to move along with the transfer member 201, so as to ensure that the driving component in the connecting shell 302 can drive the battery cell to rotate.

[0046] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple. For the relevant parts, reference can be made to the partial description of the method embodiments.
