Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery core flipping mechanism. Background Art

[0002] During the production process, single-cell batteries, specifically square-shell batteries, need to be constantly flipped at a certain angle according to processing requirements to expose a certain surface for specific processing steps. For example, when the top cover of the battery cell needs to be processed, the top cover needs to be set upward, while when it is coated, the bottom surface of the battery cell is generally required to be set upward. In practice, the flipping operation is performed using a battery cell flipping mechanism. However, when the existing flipping mechanism is in operation, the flipped battery cell structure, such as the top cover or bottom surface, is not easy to correspond to the spatial position of the processing structure in the subsequent process, and adjustment is difficult.

[0018] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] Please refer to Figures 1 to 3 A cell flipping mechanism 1 includes a fixed transfer plate 10 and a movable transfer plate 11. The movable transfer plate 11 is adjustably mounted on the fixed transfer plate 10 and can move relative to the fixed transfer plate 10 along a first direction X. A flip assembly 13 and a first driving member 12 are rotatably mounted on the fixed transfer plate 10. The first driving member 12 is used to drive the flip assembly 13 to rotate. The single cell c is fixed to the flip assembly 13. Specifically, Figure 1 As shown, the movable transfer plate 11 is slidably connected to the fixed transfer plate 10 via a slide rail and slider assembly. The fixed transfer plate 10 is equipped with a cylinder for driving the movable transfer plate 11 relative to the fixed transfer plate 10. In this embodiment, after the flip assembly 13 flips the individual battery cells c to a certain angle, the movable transfer plate 11 moves relative to the fixed transfer plate 10 to specifically adjust the individual battery cells c so that their spatial position corresponds to the spatial position of the processing structure in subsequent steps. This operation is simple and easy to implement.

[0022] like Figures 1 to 3As shown, the flip assembly 13 includes a flip seat 131 rotatably mounted on the movable plate 11, and the flip seat 131 is provided with a first reference block 132 and a second reference block 134, as well as a first positioning block 133 and a second positioning block 135; the first positioning block 133 is arranged opposite to the first reference block 132, and the first positioning block 133 can approach or move away from the first reference block 132 along the first direction X, the second positioning block 135 is arranged opposite to the second reference block 134, and the second positioning block 135 can approach or move away from the second reference block 134 along the second direction Y; the first direction X is perpendicular to the second direction Y, and the second direction Y is parallel to the rotation axis of the flip seat 131; the single battery cell c is in a space defined by the first reference block 132, the second reference block 134, the first positioning block 133 and the second positioning block 135. More specifically, two supports 14 are provided on the movable plate 11, spaced apart in the second direction Y. The flip seat 131 is rotatably mounted on the supports 14 via bearings. Specifically, the flip seat 131 is rotatably mounted on the movable plate 11 via the supports 14. The first drive member 12 is a motor, located on one of the supports 14. The motor's output shaft is in driving connection with the flip seat 131 to drive its rotation. In this embodiment, the first drive member 12 drives the flip seat 131 to rotate 90 degrees, so that the bottom surface of the battery cell faces upward along the longitudinal direction Z.

[0023] Furthermore, a supporting bar 136 is provided on the flip seat 131. The supporting bar 136 extends along the first direction X. The first reference block 132 is located at one end of the supporting bar 136, and the first positioning block 133 is located at the other end of the supporting bar 136. Correspondingly, the second positioning block 135 is located on one side of the supporting bar 136 in the second direction Y, and the second reference block 134 is located on the other side of the supporting bar 136 in the second direction Y. During use, the single cell c is placed on the supporting bar 136, and a support force is provided for the single cell c in the longitudinal direction Z before the single cell c is flipped. That is, after the single cell c is transferred to the flip mechanism 1 by the loading mechanism, it is first placed on the supporting bar 136, and finally the positioning block and the reference block cooperate to position and fix the single cell c.

[0024] Specifically, if Figure 2 and Figure 3 As shown, the first positioning block 133 and the second positioning block 135 are both driven by a cylinder mounted on the flip base 131. The first reference block 132 is fixedly mounted on the support bar 136, and the second reference block 134 is fixedly mounted on the flip base 131. Optionally, the support bar 136, the positioning blocks, and the reference blocks are provided in two sets, spaced apart along the second direction Y. This allows processing of two single cells c at a time, improving efficiency.

[0025] The second reference block 134 and / or the second positioning block 135 are provided with positioning grooves into which the single cell c is snapped. The positioning grooves are used to secure the single cell c to prevent it from being separated from the support bar 136, i.e., the flipping mechanism 1, during flipping.

[0026] In some embodiments, as Figure 4 As shown, the first reference block 132 is adjustably arranged on the flip seat 131, and the first reference block 132 can move along the second direction Y. Specifically, the first reference block 132 is slidably connected to the flip seat 131 through a slide rail slider assembly, and the first reference block 132 is driven by a cylinder to move along the second direction Y. It should be noted that, in this embodiment, the bottom surface of the battery cell is attached to the first reference block 132. In this way, when the single battery cell c is flipped to the bottom surface of the battery cell facing upward along the longitudinal direction Z, the first reference block 132 can be separated from the bottom surface of the battery cell by moving along the second direction Y, creating a space adjustment for the subsequent processing equipment or transfer mechanism to operate the single battery cell c. It is also worth noting that, in this embodiment, the movable transfer plate 11 is driven by a linear module to move relative to the fixed transfer plate 10.

[0027] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
