[0002] With the rapid development of electronic technology and new energy industries, the battery industry is also developing continuously. Among them, lithium-ion cylindrical batteries are a type of battery commonly used in daily life and automotive electronics. In the production process of lithium batteries, it is necessary to load the battery cells into the battery cell shell, that is, push the delivered battery cells into the battery cell shell. The existing shell entry equipment usually adopts segmented shell entry, that is, insert one section of the battery cell first, and then insert the other section of the battery cell into the shell through the push plate. However, at this time, the outer side of the battery cell needs to be clamped by a clamp, resulting in the battery cell cannot be fully inserted into the shell. Some of the existing shell entry equipment pushes the uninserted part in through the top plate, but the top plate is easy to damage the end of the battery cell, resulting in defective products and a low product qualification rate. Therefore, it is necessary to improve the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0015] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0018] like Figure 1-2 As shown, the battery cell shell rotation and ejection mechanism includes a frame 1, on which a rotating shaft 2 and a driving motor 3 connected to the rotating shaft 2 are provided, a rotating frame 4 is sleeved on the outer side of the rotating shaft 2, and a plurality of battery cell shell brackets are provided on the rotating frame 4, the battery cell shell brackets include a first battery cell shell bracket 5, a second battery cell shell bracket 6, a third battery cell shell bracket 7 and a fourth battery cell shell bracket 8 which are arranged in sequence, and the first battery cell shell bracket 5, the second battery cell shell bracket 6, the third battery cell shell bracket 7 and the fourth battery cell shell bracket 8 are distributed in sequence at the vertices of a square. It can be understood that the frame 1 can be made of aluminum alloy, etc., and the drive motor 3 can be an electric motor, etc., which is used to drive the rotating shaft 2 to rotate, thereby driving the rotating frame to rotate, and then driving the battery cell shell bracket to perform circular motion; the first battery cell shell bracket 5 receives the battery cell shell with the battery cell delivered from the previous station (at this time, the opening of the battery cell shell faces downward, and the battery cell has not completely entered the battery cell shell). When the first battery cell shell bracket 5 rotates to the original position of the third battery cell shell bracket 7, the battery cell completely enters the battery cell shell under the action of its own gravity. At this time, the opening of the battery cell shell faces upward, and the battery cell is completely put into the shell. At this time, the battery cell can be pushed to the next station through the pushing mechanism on the production line, and the cycle is repeated.

[0019] Specifically, the battery shell bracket is composed of a battery shell adsorption plate 9, a fixed connection plate 10 and a plurality of battery core blocking columns 11. The fixed connection plate 10 is connected to the rotating frame 4, the battery core blocking column 11 and the battery shell adsorption plate 9 respectively; the battery shell adsorption plate 9 is provided with a first adsorption groove 12 and a second adsorption groove 13 aligned with the battery core blocking column 11, and a baffle 16 is provided at one end of the first adsorption groove 12 and the second adsorption groove 13; the battery shell adsorption plate 9 is made of a magnet material. It can be understood that the battery shell adsorption plate 9 is used to absorb the battery shell to prevent it from falling, and the battery core blocking column is used to block the end of the battery core to prevent it from falling out of the battery shell during rotation.

[0020] Specifically, the frame 1 includes a shaft mounting frame 14 and a motor mounting frame 15, and the shaft 2 and the drive motor 3 are respectively mounted on the shaft mounting frame 14 and the motor mounting frame 15; the first battery cell shell bracket 5 and the second battery cell shell bracket 6 are respectively symmetrically arranged with the third battery cell shell bracket 7 and the fourth battery cell shell bracket 8. It can be understood that the front end of the first battery cell shell bracket receives the battery cell shell ejection mechanism of the previous station, and the back of the third battery cell shell bracket 6 receives the battery cell shell ejection mechanism of the next station. The battery cell shell rotation ejection mechanism is a part of the production line, which is mainly used for battery cell shell transfer and battery cell shell entry; each of the above battery cell shell brackets has the same size and shape, but different installation angles, and is installed in sequence along the circumferential direction.

[0021] It can be understood that the utility model has a reasonable design and a unique structure. A battery cell shell bracket is arranged on the rotating frame 4 to support the battery cell shell. The driving motor 3 drives the rotating shaft 2 to rotate, thereby driving the rotating frame 4 to rotate. When the first battery cell shell bracket 5 rotates to the position of the original third battery cell shell bracket 7, the battery cell in the battery cell shell on the first battery cell shell bracket 5 falls into the battery cell shell under the action of its own gravity. There is no need to use a top plate to push it in, which avoids damage to the battery cell and improves the qualified rate of the product. The qualified rate is relatively high.

[0022] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
