Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] Refer to the following Figures 1 to 6 Describe the module stacking tooling and battery assembly equipment according to some embodiments of the present application.

[0038] See also Figures 1 to 6 As shown, an embodiment of the first aspect of the present application provides a module stacking tool for stacking multiple single cells along a first direction F1 to form a module 10. The module stacking tool includes a first drive unit 51, a pressure sensor 9, a first clamping assembly 1, and a second clamping assembly 2. The first clamping assembly 1 and the second clamping assembly 2 are arranged opposite each other along the first direction F1. The first drive unit 51 is in transmission connection with at least one of the first clamping assembly 1 and the second clamping assembly 2 to drive the first clamping assembly 1 and the second clamping assembly 2 toward and away from each other along the first direction F1. The pressure sensor 9 is in communication connection with the first drive unit 51, and the pressure sensor 9 is connected to the first clamping assembly 1 and / or the second clamping assembly 2 to obtain the clamping force applied by the module stacking tool to the module 10 in the first direction F1.

[0039] In the module stacking tooling provided by the above technical features, the first driving part 51 is connected to at least one of the first clamping assembly 1 and the second clamping assembly 2 which are arranged opposite to each other along the first direction F1, and the pressure sensor 9 which is connected to the first driving part 51 is arranged on the first clamping assembly 1 and / or the second clamping assembly 2. In this way, the first driving part 51 can control the first clamping assembly 1 and the second clamping assembly 2 to move closer to each other to perform the action of clamping the module 10 of the module stacking tooling; if the clamping force applied to the module 10 by the first clamping assembly 1 and the second clamping assembly 2 obtained by the pressure sensor 9 is greater than that of the first clamping assembly 1 and the second clamping assembly 2, the clamping force applied to the module 10 by the first clamping assembly 1 and the second clamping assembly 2 is greater than that of the second clamping assembly 2. When the holding force reaches a predetermined value, the first driving part 51 can be controlled to stop the first clamping component 1 and the second clamping component 2 from approaching each other, so that the first clamping component 1 and the second clamping component 2 can maintain the clamping force applied to the module 10 equal to the predetermined value; if the clamping force applied to the module 10 by the first clamping component 1 and the second clamping component 2 obtained by the pressure sensor 9 exceeds the predetermined value or the module stacking tooling needs to release the module 10, the first driving part 51 can be used to control the first clamping component 1 and the second clamping component 2 to move away from each other to execute the action of the module stacking tooling to release the module 10. On the one hand, the first driving part 51 controls the approach / distancing action of the first clamping component 1 and the second clamping component 2, replacing the driving form of manually screwing the screw-type clamp, which can effectively improve the clamping / releasing efficiency of the module stacking tooling on the module 10 and improve the assembly efficiency of the module 10; on the other hand, the real-time monitoring of the pressure sensor 9 ensures that the clamping force applied by the module stacking tooling to the module 10 can always meet the predetermined value, thereby ensuring the assembly consistency of modules 10 of different batches and effectively reducing the chance of the module 10 being clamped by the module stacking tooling.

[0040] like Figures 1 to 6 As shown, F1 shown in the figure may be an example of the first direction F1, and F2 shown in the figure may be an example of the second direction F2 described below. The first direction F1 and the second direction F2 intersect. Preferably, the first direction F1 and the second direction F2 are perpendicular to each other to accommodate the structure of most prismatic single cells. For ease of description, a direction perpendicular to the plane defined by both the first and second directions F1 and F2 is defined as a third direction F3. F3 shown in the figure may be an example of the third direction F3.

[0041] Preferably, if Figure 1 、 Figure 4 and Figure 6As shown, the figure shows an example in which the first clamping component 1 is transmission-connected to the first driving part 51 and the second clamping component 2 is fixedly arranged. In other words, in the process of the first clamping component 1 and the second clamping component 2 approaching / moving away from each other, the second clamping component 2 is fixed, and the first driving part 51 drives the first clamping component 1 to approach / move away from the second clamping component 2. In this way, the module 10 can be positioned by the fixed arrangement of the second clamping component 2, which facilitates the reference positioning of the module 10 in subsequent processing steps.

[0042] However, it is not limited to this. Optionally, as not shown in the figure, the module stacking tooling can also be a second clamping component connected to the first driving part in a transmission manner, and the first clamping component is fixedly arranged. In other words, in the process of the first clamping component and the second clamping component approaching / moving away from each other, the first clamping component is fixed, and the first driving part drives the second clamping component to approach / move away from the first clamping component.

[0043] Optionally, not shown in the figure, the above-mentioned module stacking tooling can also be a first driving part that is respectively connected to the first angle assembly and the second clamping assembly in a transmission manner. In other words, in the process of the first clamping assembly and the second clamping assembly approaching / moving away from each other, the first driving part drives the first clamping assembly and the second clamping assembly to move toward / away from each other at the same time.

[0044] Optionally, not shown in the figures, the module stacking tooling may further include two first driving parts, which may be respectively connected to the first angle assembly and the second clamping assembly in a transmission manner to respectively drive the first angle assembly and the second clamping assembly to move.

[0045] The structure of the module stacking fixture will be described in detail below by taking an example in which the first clamping assembly 1 is transmission-connected to the first driving portion 51 and the second clamping assembly 2 is fixedly arranged.

[0046] Preferably, if Figures 1 to 6 As shown, the module stacking tooling may further include a support portion 6 for supporting the module 10. The first drive unit 51, the first clamping assembly 1, and the second clamping assembly 2 are all disposed on the support portion 6. The first clamping assembly 1 and the support portion 6 are slidably connected along a first direction F1, while the second clamping assembly 2 is fixedly connected to the support portion 6.

[0047] Preferably, the support portion 6 may include a support plate 61 perpendicular to the third direction F3. The first clamping assembly 1 and the second clamping assembly 2 may be disposed on the same side of the support plate 61. The second clamping assembly 2 and the support plate 61 may be fixedly connected via a connector. Optionally, the connector may be a bolt, screw, rivet, or the like.

[0048] Preferably, if Figures 1 to 6As shown, the first clamping assembly 1 may include a connecting block 11 , and the first clamping assembly 1 may be transmission-connected to the first driving portion 51 via the connecting block 11 .

[0049] Optionally, the first clamping assembly 1 may further include a first guide rail extending along the first direction F1 , the first guide rail being fixed to the supporting portion 6 , and the connecting block 11 may be slidably connected to the first guide rail to improve the movement accuracy of the first clamping assembly 1 .

[0050] Preferably, the number of the above-mentioned first guide rails can be multiple, and the multiple first guide rails can be fixed to the supporting part 6 side by side and at intervals along the second direction F2. The above-mentioned connecting block 11 is slidingly connected to the multiple first guide rails respectively to improve the movement stability of the connecting block 11.

[0051] like Figure 6 As shown, the module 10 may include multiple columns of battery packs, each of which may include multiple single cells stacked along a first direction F1 , and the multiple columns of battery packs may be arranged side by side along a second direction F2 .

[0052] Preferably, if Figure 6 As shown, when the module stacking tool is in a state of clamping the module 10, at least a portion of the connecting block 11 can abut against the module 10, so that when the module 10 includes multiple columns of battery packs, the connecting block 11 can synchronously clamp the multiple columns of battery packs.

[0053] Preferably, if Figure 6 As shown, the first clamping assembly 1 may include a plurality of push-pushing parts, which are arranged side by side on the connecting block 11 along the second direction F2. Each push-pushing part can be arranged corresponding to a column of battery packs to ensure that the clamping force of the module stacking tooling on each column of battery packs is evenly distributed through the push-pushing parts.

[0054] Preferably, if Figure 2 and Figure 5 As shown, the push-pushing portion includes a push-pushing block 12 and a driving member 13. The driving member 13 is fixed to the connecting block 11. The driving member 13 is in transmission connection with the push-pushing block 12 to independently drive the corresponding push-pushing block 12 to tighten / relax the battery pack of the corresponding column. In this way, the independent movement of the push-pushing block 12 driven by the driving member 13 can effectively realize the independent adjustment of the clamping force of each column of battery packs by the module stacking tooling.

[0055] Optionally, the driving member 13 may be a linear driving device, such as an electric cylinder, a pneumatic cylinder, a linear motor, etc.

[0056] Preferably, if Figure 2 and Figure 5As shown, the above-mentioned push-pushing part may further include a push rod 14, one end of the above-mentioned push-pushing block 12 in the third direction F3 is hinged to the connecting block 11, the other end of the push-pushing block 12 in the third direction F3 is hinged to the first end of the push rod 14, and the driving member 13 is hinged to the second end of the push rod 14. In this way, on the one hand, the driving member 13 can transmit the output power to the end of the module 10 away from the connecting block 11 in the third direction F3 via the push rod 14, so as to balance the force applied by the connecting block 11 to the module 10, thereby improving the uniformity of the force applied by the first clamping assembly 1 to the module 10 in the third direction F3; on the other hand, the space occupied by the push-pushing block 12 is effectively saved.

[0057] Optionally, the push-split portion may further include a hinge, through which the drive member 13 and the push rod 14 may be hinged to increase the degree of freedom of hinge between the drive member 13 and the push rod 14, thereby preventing the drive member 13 and the push rod 14 from self-locking in a narrow space, causing the push-split portion to fail.

[0058] Preferably, if Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the module stacking tooling may further include a transmission assembly 7, through which the first drive unit 51 and the first clamping assembly 1 are connected, and the pressure sensor 9 may be arranged on the transmission assembly 7 to obtain the power value output by the first drive unit 51 to the first clamping assembly 1.

[0060] Alternatively, as Figure 6 As shown, the supporting portion 6 may further include a supporting rib 62 , which may be fixedly disposed on the side of the supporting plate 61 facing away from the first clamping assembly 1 , so as to improve the supporting strength of the supporting plate 61 .

The guide portion 72 is arranged at one end of the supporting portion 6 in the first direction F1, and the first driving portion 51 and the first clamping assembly 1 are respectively connected to the transmission portion 71.

[0062] Optionally, the guide portion 72 may be provided with a second guide rail extending along the first direction F1 , and the transmission portion 71 is slidably connected to the second guide rail.

[0063] Preferably, if Figure 4 As shown, relative to the supporting plate 61, the transmission portion 71 can extend toward both sides of the supporting plate 61 along the third direction F3. Figure 4 Taking the illustrated orientation as an example, the upper portion of the transmission portion 71 can be connected to the connecting block 11 to push the connecting block 11 along the first guide rail. The lower portion of the transmission portion 71 can be connected to the first drive portion 51 to push the transmission portion 71 along the second guide rail via the first drive portion 51, thereby outputting the power of the first drive portion 51 to the outside.

[0064] Preferably, if Figure 1 and Figure 4 As shown, the pressure sensor 9 can be arranged on the upper side of the transmission part 71 facing the connecting block 11. The connecting block 11 is fixed with a driving rod 15 extending along the first direction F1.

[0065] Preferably, if Figure 1 As shown, the connecting block 11 is also fixed with a guide rod 16 extending along the first direction F1, and the transmission part 71 is provided with a guide hole passing through the transmission part 71 along the first direction F1.

The second driving part 52 is transmission-connected to at least one of the first clamping component 1 and the second clamping component 2 to drive the third clamping component 3 and the fourth clamping component 4 to approach and move away from each other along the second direction F2. In this way, on the one hand, the position of the module 10 in the second direction F2 is restricted by the approach and distance of the third clamping component 3 and the fourth clamping component 4; on the other hand, at least one of the third clamping component 3 and the fourth clamping component 4 can be moved in the second direction F2, so that the distance between the third clamping component 3 and the fourth clamping component 4 can be adjusted to adapt to modules 10 of different widths, thereby improving the adaptability of the module stacking tooling.

[0067] Preferably, if Figure 1 and Figure 6As shown, the number of the above-mentioned second driving parts 52 can be multiple, a part of the multiple second driving parts 52 can be transmission-connected to the third clamping assembly 3, and another part of the multiple second driving parts 52 can be transmission-connected to the fourth clamping assembly 4 to achieve independent control of the third clamping assembly 3 and the fourth clamping assembly 4.

[0068] Preferably, if Figure 1 and Figure 6 As shown, the module stacking tooling can also include a control unit 8. The first drive unit 51, the second drive unit 52, the pressure sensor 9 and the drive member 13 can be respectively connected to the control unit 8 for communication, so as to realize the control of the module stacking tooling execution action through the control unit 8.

[0069] Preferably, the first driving part 51 and the second driving part 52 may also be the linear driving devices.
