In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0046] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0048] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and may be direct contact or contact through an intermediate medium layer. It may be contact with essentially no interaction force between the two contacting parties, or it may be contact with interaction force between the two contacting parties.

[0050] In the related art, the formation assembly is fixed on a press, and the press is driven by a driving device to approach the battery cell to drive the formation assembly to approach. After the press moves to a preset position, the formation assembly is aligned with the pole and injection hole of the battery cell to perform formation work on the battery cell. During the battery formation process, the clamping assembly applies pressure to the battery cell to squeeze the battery cell to squeeze out the gas generated inside the battery cell. The battery cell is easily deformed after being squeezed, and the position of the pole and injection hole on the battery cell will also change. Since the position of the formation assembly on the press is fixed, the position deviation between the formation assembly and the pole and injection hole of the battery cell is large, and there is a deviation between the formation assembly and the pole and injection hole of the battery cell, which makes it difficult to align.

[0051] The present application provides a battery formation device, which is arranged on a sliding component 1 and connects a formation component 3 to the sliding component 1. The sliding component 1 drives the formation component 3 to move, thereby reducing the position deviation between the formation component 3 and the pole and injection hole of the battery cell 9, and improving the alignment accuracy between the formation component 3 and the pole and injection hole of the battery cell 9.

[0052] The embodiments of the present application can be applied to battery formation. The battery formation equipment charges the battery, activates the active substances in the battery, forms a solid electrolyte interface film at the negative electrode of the battery, and the battery reacts to generate gas inside the battery. The battery formation equipment can extract the gas generated inside the battery.

[0053] For the battery formation equipment of the present application embodiment, please refer to Figure 1 to Figure 4 The battery formation equipment includes a frame 5, a press 4, a clamping assembly 2, a guide rail 6, a sliding assembly 1 and a formation assembly 3. The press 4 is movably arranged on the frame 5 along the up and down direction. The clamping assembly 2 has at least two clamping cavities 21 for placing battery cells 9. The arrangement direction of the at least two clamping cavities 21 is a first direction. The clamping assembly 2 is used for clamping the battery cells 9. The clamping assembly 2 is located below the press 4. The guide rail 6 is arranged on the press 4. The sliding assembly 1 is movably arranged on the guide rail 6. The sliding assembly 1 has a positioning portion 11. Each clamping cavity 21 is correspondingly provided with a sliding assembly 1. The cavity wall of at least one side of each clamping cavity 21 along the first direction abuts against the corresponding positioning portion 11. The formation assembly 3 is connected to the sliding assembly 1. The sliding assembly 1 drives the formation assembly 3 to slide so that the formation assembly 3 moves to a position for forming the battery cells 9.

[0054] For the convenience of explanation, a first direction and a second direction are set, and the first direction, the second direction and the up-down direction are directions intersecting each other, the first direction intersects with the second direction, the first direction intersects with the up-down direction, and the second direction intersects with the up-down direction. For the convenience of explanation, as shown by the arrows in the figure, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the up-down direction.

[0055] Exemplarily, the intersection includes perpendicular intersection, the first direction perpendicularly intersects the second direction, the first direction perpendicularly intersects the up-down direction, and the second direction perpendicularly intersects the up-down direction.

[0056] The width of the positioning portion 11 along the first direction is not greater than the width of the clamping cavity 21 along the first direction.

[0057] In the embodiment of the present application, during the battery formation process, the battery cell 9 is deformed due to the clamping force of the clamping assembly 2, and the position of the formation assembly 3 changes with the deformation of the battery cell 9. The press machine 4 moves downward, and the positioning portion 11 of the sliding assembly 1 is inserted into the corresponding clamping cavity 21. The positioning portion 11 abuts against the cavity wall of the clamping cavity 21 along a first direction. The cavity wall of the clamping cavity 21 generates a force along the first direction on the positioning portion 11 to guide the sliding assembly 1, so that the sliding assembly 1 slides along the guide rail 6. The formation assembly 3 is connected to the sliding assembly 1, and the sliding assembly 1 drives the formation assembly 3 to slide so that the formation assembly 3 moves to the position for forming the battery cell 9, thereby realizing the alignment of the formation assembly 3 with the pole and the injection hole of the battery cell 9.

[0058] In one embodiment, please refer to Figure 1 and Figure 5 The clamping assembly 2 includes a partition 22 and a main body 23. The partition 22 and the main body 23 enclose a clamping cavity 21. The partition 22 is arranged on the main body 23 along a first direction. The partition 22 is used to clamp the battery cell 9 along the first direction. The main body 23 can apply pressure to the partition 22 to make the partitions 22 approach each other along the first direction.

[0059] For example, see Figure 5 The main body 23 includes an end plate 231 and a base 232 , any two adjacent partitions 22 and the base 232 are arranged to form a clamping cavity 21 , and the partition 22 closest to the end plate 231 , the end plate 231 and the base 232 are arranged to form a clamping cavity 21 .

[0060] Exemplarily, the main body 23 includes a clamping mechanism, a guide rail, an end plate 231 and a base 232. The end plate 231 includes a first end plate 231 and a second end plate 231. The first end plate 231 is movably arranged on the base 232, and the second end plate 231 is fixed to the base 232. The partition 22 is arranged between the first end plate 231 and the second end plate 231. The partition 22 is movably connected to the guide rail. The partition 22 and the first end plate 231 are both provided with through holes for the clamping mechanism to pass through. The battery cells 9 are placed on the base 232, and the battery cells 9 are separated by the partition 22. The clamping mechanism applies pressure along the first direction to the first end plate 231, so that the partitions 22 are close to each other, thereby squeezing the battery cells 9. The partition 22 is provided with a plurality of distance blocks arranged around the partition 22, and the distance blocks bear the pressure between the partitions 22, thereby preventing the partition 22 from being compressed and deformed.

[0061] In the embodiment of the present application, a partition 22 is provided to separate the battery cells 9, and the partition 22 can disperse the pressure on the battery cells 9, which is beneficial to reducing the deformation of the battery cells 9. After the battery cells 9 are deformed by extrusion, the positioning portion 11 is inserted into the clamping cavity 21, and the positioning portion 11 abuts against the partition 22 or the main body 23. The battery pole and the injection hole are positioned by the partition 22 and the main body 23, which is beneficial to guiding the sliding assembly 1.

[0062] In one embodiment, please refer to Figure 2 and Figure 4 The positioning portion 11 has a guide surface 111, which is an inclined surface inclined along the first direction toward a side of the cavity wall away from the clamping cavity 21. The guide surface 111 abuts against the clamping assembly 2 to guide the sliding assembly 1.

[0063] Exemplarily, the guide surface 111 is an inclined surface inclined along the first direction toward a side of the cavity wall away from the clamping cavity 21 , which means that along the first direction, the width of the positioning portion 11 increases from bottom to top.

[0064] Exemplarily, along the first direction, the maximum width of the positioning portion 11 is not greater than the constrained width of the battery cell 9 along the first direction.

[0065] For example, see Figure 2 and Figure 4 , the guide surface 111 is a curved surface.

[0066] Exemplarily, the guide surface 111 is a smooth inclined surface.

[0067] In the embodiment of the present application, the guide surface 111 is an inclined surface inclined along the first direction toward the side of the cavity wall away from the clamping cavity 21. During the pressing process of the press machine 4, the guide surface 111 abuts against the cavity wall of the clamping cavity 21, and the guide surface 111 moves downward relative to the cavity wall of the clamping cavity 21. The inclined surface facilitates the movement of the guide surface 111, which is convenient for guiding the sliding assembly 1, and guiding the formation assembly 3 to the formation position corresponding to the battery cell 9.

[0071] In the embodiment of the present application, the guide block 13 protrudes downward from the slide 12. During the pressing process of the press machine 4, when the formation assembly 3 is far away from the battery cell 9, the guide block 13 is inserted into the clamping cavity 21 and abuts against the cavity wall of the clamping cavity 21 to guide the slide 12. After the slide 12 is adjusted into place along the first direction, the formation assembly 3 reaches a position in the first direction where the battery cell 9 can be formed, which is conducive to accurately adjusting the relative position of the formation assembly 3 and the battery cell 9.

[0072] In one embodiment, the guide block 13 is detachably connected to the slide seat 12 .
