[0034] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present utility model clearer, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners

[0035] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside 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 present utility model can be understood according to specific situations

[0036] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above and over", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below and under", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature

[0037] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings

[0038] When the existing battery formation equipment conducts formation tests on battery cells, it manually scans and identifies the battery cells to be formed outside the battery formation equipment. Then, according to the order of the scanned barcodes, it corresponds to the channel numbers of the battery formation equipment one by one, and places the battery cells to be formed in the formation test positions of the battery formation equipment in sequence. However, in the above operations, it is easy for the placement position of the battery cells to be formed to be incorrect due to human reasons after scanning, and it does not correspond to the channel numbers of the battery formation equipment one by one. Moreover, when placing the battery cells to be formed in the formation test positions, it is impossible to visually judge whether the battery cells to be formed are placed in place, which greatly reduces the reliability of the formation test of the battery cells to be formed.

[0039] To solve the above problems, as Figure 1 and Figure 2 shown, this embodiment provides a battery formation clamping device. The battery formation clamping device includes a clamping assembly 1. The clamping assembly 1 includes an insulating bearing film 11 and a plurality of clamping plates 12. The plurality of clamping plates 12 are arranged at intervals in the horizontal direction (the left-right direction in the figure). A clamping space 13 is formed between two adjacent clamping plates 12. An insulating bearing film 11 is provided in each clamping space 13. The insulating bearing film 11 is used to support the battery cell 20 to be formed, and the insulating bearing film 11 has a lifting position and a reset position. When the insulating bearing film 11 is in the lifting position, the insulating bearing film 11 supports the battery cell 20 to be formed and protrudes out of the clamping space 13. When the insulating bearing film 11 is in the reset position, the insulating bearing film 11 supports the battery cell 20 to be formed and retracts into the clamping space 13.

[0040] For the battery formation clamping device provided in this embodiment, each battery cell 20 to be formed can be first placed on the insulating bearing film 11 in the clamping space 13. Then, as Figure 1 shown, when the insulating bearing film 11 is in the lifting position, the insulating bearing film 11 supports the battery cell 20 to be formed and protrudes out of the clamping space 13, so as to assist the scanning device to scan and identify the battery cell 20 to be formed that protrudes out of the clamping space 13. When the scanning and identification are completed, as Figure 2 shown, the insulating bearing film 11 is in the reset position. At this time, the insulating bearing film 11 supports the battery cell 20 to be formed and retracts into the clamping space 13, and then the battery cell 20 to be formed that retracts into the clamping space 13 can be subjected to the formation operation, so as to ensure that the battery cell 20 to be formed after scanning is accurately placed in the clamping space 13 for formation, and the reliability of the formation test of the battery cell 20 to be formed is ensured.

[0041] It should be noted that when the insulating carrier film 11 supports the battery cell 20 to be formed and protrudes from the clamping space 13, it is only necessary to make the part of the battery cell 20 to be formed with a barcode protrude from the clamping space 13, so as to avoid the clamping space 13 blocking the barcode on the battery cell 20 to be formed, ensure the barcode scanning and identification of the battery cell 20 to be formed by the barcode scanning device, and also ensure the stable supporting effect of the insulating carrier film 11 on the battery cell 20 to be formed. Optionally, in this embodiment, when the insulating carrier film 11 supports the battery cell 20 to be formed and protrudes from the clamping space 13, the battery cell 20 to be formed can be in a half-inserted state in the clamping space 13.

[0042] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the insulating carrier film 11 includes a first side wall 111, a bottom wall 112, and a second side wall 113 that are connected in sequence. Among them, the first side wall 111 and the second side wall 113 are arranged opposite to each other in the left-right direction. The first side wall 111 is connected to one of the two adjacent clamping plates 12, the second side wall 113 is connected to the other of the two adjacent clamping plates 12, the bottom wall 112 supports the battery cell 20 to be formed, and the battery cell 20 to be formed is located between the first side wall 111 and the second side wall 113.

[0043] As Figure 1 shown, when the insulating carrier film 11 is in the jacking position, the bottom wall 112 bends and protrudes upward relative to the first side wall 111 and the second side wall 113; as Figure 2 shown, when the insulating carrier film 11 is in the reset position, the bottom wall 112 moves downward and resets relative to the first side wall 111 and the second side wall 113. The above structural design of the insulating carrier film 11 enables the bottom wall 112 to bend and protrude upward relative to the first side wall 111 and the second side wall 113 when the insulating carrier film 11 is in the jacking position, so that the bottom wall 112 upwardly supports the battery cell 20 to be formed, making the battery cell 20 to be formed protrude upward from the clamping space 13; when the insulating carrier film 11 is in the reset position, the bottom wall 112 moves downward and resets relative to the first side wall 111 and the second side wall 113, so that the battery cell 20 to be formed moves downward together with the bottom wall 112 under the action of its own gravity, thus ensuring that the battery cell 20 to be formed retracts downward into the clamping space 13.

[0044] Optionally, in this embodiment, the insulating carrier film 11 can be a mylar film. The mylar film has good insulation performance, thus ensuring the insulation effect between the battery cells 20 to be formed. In addition, the mylar film also has good mechanical flexibility. The mylar film can be bent and deformed under the action of an external force, and the deformed mylar film is also easy to reset.

[0045] Optionally, in this embodiment, a single mylar film can be used for multiple clamping spaces 13 arranged in the left-right direction. As long as the mylar film is bent multiple times, the first side wall 111, the bottom wall 112, and the second side wall 113 are all present in each clamping space 13, and it is ensured that both the first side wall 111 and the second side wall 113 are connected to the corresponding clamping plate 12. Optionally, in other embodiments, a separate mylar film can also be provided in each clamping space 13, and the mylar film in each clamping space 13 is designed in the form of the first side wall 111, the bottom wall 112, and the second side wall 113.

[0046] Optionally, in this embodiment, the extension length of the clamping plate 12 in the front-rear direction can be extended, so that the clamping spaces 13 formed between adjacent two clamping plates 12 can accommodate multiple cells to be formed 20 at intervals in the front-rear direction, thereby increasing the number of cells to be formed 20 placed by the clamping assembly 1 and improving the test efficiency. It should be noted that the above design only needs to ensure that the adjacent two cells to be formed 20 are arranged at intervals in the front-rear direction.

[0047] In this embodiment, as Figure 1 and Figure 2 shown, the battery formation clamping device further includes a lifting assembly 2. The lifting assembly 2 can be connected to the bottom of the insulating carrier film 11, and the lifting assembly 2 is used to lift the insulating carrier film 11 from the reset position to the lifting position. Specifically, in this embodiment, the lifting assembly 2 is connected to the bottom wall 112 of the insulating carrier film 11. When the lifting assembly 2 lifts the bottom wall 112 upward, since the first side wall 111 and the second side wall 113 on both sides of the bottom wall 112 are connected to the corresponding clamping plates 12, it can be made such that the bottom wall 112 bends and protrudes upward relative to the first side wall 111 and the second side wall 113, so that the bottom wall 112 upwardly supports the cell to be formed 20.

[0048] Optionally, in this embodiment, the lifting assembly 2 can be fixedly connected to the bottom wall 112. When the lifting assembly 2 resets downward, the lifting assembly 2 pulls the bottom wall 112 to move downward and reset relative to the first side wall 111 and the second side wall 113. Optionally, in other embodiments, the lifting assembly 2 can also be in abutting connection with the bottom wall 112. When the lifting assembly 2 resets downward, the lifting assembly 2 removes the lifting driving force on the bottom wall 112. At this time, the bottom wall 112 moves downward and resets relative to the first side wall 111 and the second side wall 113 under the action of the gravity of the cell to be formed 20.

[0049] In this embodiment, as Figure 1 and Figure 2As shown, the lifting assembly 2 includes a lifting driving member 21 and a lifting plate member 22. Among them, the lifting plate member 22 is connected to the output end of the lifting driving member 21. A plurality of lifting convex plates 221 are arranged at intervals on the lifting plate member 22. Each lifting convex plate 221 is directly opposite to a clamping space 13 in the vertical direction, and the lifting convex plate 221 is connected to the bottom wall 112 of the insulating carrier film 11. When the lifting driving member 21 drives the lifting plate member 22 to move upward, the lifting convex plate 221 drives the corresponding bottom wall 112 to bend and bulge upward, so that the bottom wall 112 upwardly supports the cell 20 to be formed. When the lifting driving member 21 drives the lifting plate member 22 to move downward and reset, the lifting convex plate 221 drives the corresponding bottom wall 112 to move downward and reset. Optionally, in this embodiment, each lifting convex plate 221 is fixedly connected to the upper-facing bottom wall 112. In other embodiments, each lifting convex plate 221 may also be in abutting connection with the upper-facing bottom wall 112.

[0050] In this embodiment, a plurality of lifting convex plates 221 may be arranged at intervals in the left-right direction, so that each lifting convex plate 211 is directly opposite to a cell 20 to be formed in a clamping space 13. It should be noted that a plurality of lifting convex plates 221 may be arranged at intervals in the front-rear direction, and each lifting convex plate 221 spaced in the front-rear direction is directly opposite to the same clamping space 13 in the vertical direction. Thus, a plurality of cells 20 to be formed can be arranged in a clamping space 13, and it is convenient to lift a plurality of cells 20 to be formed in the same clamping space 13 at the same time.

[0051] Optionally, in this embodiment, the lifting driving member 21 may be a lifting cylinder, which has the advantages of reliable operation and convenient installation. In other embodiments, the lifting driving member 21 may also be a linear motor or other forms of driving members.

[0052] Optionally, in this embodiment, a plurality of lifting driving members 21 are arranged at intervals. The output ends of the plurality of lifting driving members 21 are all connected to the lifting plate member 22. The plurality of lifting driving members 21 jointly drive the lifting plate member 22 to move up and down, ensuring the stability and reliability of the lifting movement of the lifting plate member 22. Optionally, in this embodiment, a lifting driving member 21 may be arranged at each of the four corners of the lifting plate member 22. In other embodiments, the number of lifting driving members 21 arranged may be set according to requirements.

[0053] In this embodiment, as Figure 1 and Figure 2 shown, the lifting assembly 2 further includes a fixed base 23, and the lifting driving member 21 is installed on the fixed base 23. By installing the lifting driving member 21 on the fixed base 23, the stability of the installation of the lifting driving member 21 is ensured.

[0054] Specifically, as Figure 1 andFigure 2 As shown, the fixed base 23 includes a fixed bottom plate 231 and a mounting plate 232. Among them, the mounting plate 232 is L-shaped. One side wall of the mounting plate 232 is connected to the fixed bottom plate 231, and the other side wall of the mounting plate 232 is connected to the lifting driving member 21. The above arrangement effectively ensures the mounting area between the mounting plate 232 and the fixed bottom plate 231, and also ensures the mounting area between the mounting plate 232 and the lifting driving member 21, further ensuring the stability and reliability of the installation and fixation of the lifting driving member 21.

[0055] This embodiment also provides a battery forming device. The battery forming device includes a code scanning device, a forming test device, and the above-mentioned battery forming clamping device. The code scanning device is used to scan and identify the battery cell to be formed 20 protruding from the clamping space 13, and the forming test device is used to connect and conduct the battery cell to be formed 20 retracted into the clamping space 13, so as to perform a forming operation on the battery cell to be formed 20. By applying the above-mentioned battery forming clamping device in the battery forming device provided in this embodiment, the code scanning device can scan and identify the battery cell to be formed 20 protruding from the clamping space 13. After the code scanning and identification are completed, the insulating carrier film 11 supports the battery cell to be formed 20 and retracts it into the clamping space 13, and the forming test device can perform a forming operation on the battery cell to be formed 20 retracted into the clamping space 13, ensuring that the battery cell to be formed 20 after code scanning is accurately placed in the clamping space 13 for forming, and ensuring the reliability of the forming test of the battery cell to be formed 20.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
