[0040] See Figures 1 to 3 As shown, the embodiment of the present application provides a battery module extrusion tooling, including: a bottom plate 1, an extrusion mechanism 4, two side plate assemblies 2, and two end plate assemblies 3. The two side plate assemblies are both arranged on the bottom plate 1, and the two side plate assemblies 2 are arranged at intervals in the first direction in sequence. The two side plate assemblies 2 can both move and be fixed in the first direction. The two end plate assemblies 3 are both arranged on the bottom plate 1, and the two end plate assemblies 3 are arranged at intervals in the second direction in sequence. The two end plate assemblies 3 can both move and be fixed in the second direction. A connection seat 31 is arranged on one end plate assembly 3. The extrusion mechanism 4 is arranged on the bottom plate 1. The extrusion mechanism 4 includes a bracket 41 and a rotating shaft 42. The bracket 41 is fixed to the bottom plate 1. The bracket 41 has a threaded groove. The rotating shaft 42 is threadedly connected to the threaded groove. The rotating shaft 42 is rotatably connected to the connection seat 31. A pressure sensor is arranged on the rotating shaft 42 or the connection seat 31. The rotation of the rotating shaft 42 can drive the corresponding end plate assembly 3 to move.

[0041] The battery module extrusion tooling of the present application can monitor the extrusion force during the process of extruding the battery module, avoiding damage to the battery cells. The battery module extrusion tooling of the present application can accommodate the production of multiple products and only requires simple adjustment on the original basis.

[0042] The connection seat 31 may include a sleeve portion connected to the end plate assembly 3, and the rotating shaft 42 is rotatably connected to the sleeve portion, and the rotating shaft 42 can move along the axial direction of the rotating shaft 42. By rotating the rotating shaft 42, the rotating shaft 42 can be pressed against the connection seat 31 or the end plate assembly 3, so that the pressure sensor can detect the extrusion force. The pressure sensor can be arranged at the end of the rotating shaft 42. During the process of the rotating shaft 42 pushing forward, the pressure sensor and the bottom wall of the connection seat 31 are pressed against each other, and the detection value of the pressure sensor can be obtained smoothly. The pressure sensor can also be arranged on the bottom wall of the sleeve portion of the connection seat 31. During the process of the rotating shaft 42 pushing forward, it directly acts on the pressure sensor, so that the pressure sensor obtains the pressure value. Of course, during this process, the rotating shaft 42 rotates relative to the connection seat 31. The pressure sensor can be rotatably connected to the end position of the rotating shaft 42. During the process of the rotating shaft 42 pushing forward, the pressure sensor contacts the bottom wall of the connection seat 31. The pressure sensor will not rotate under the limit of the connection seat 31, but can detect the pressure applied by the rotating shaft 42.

[0043] In some possible implementations, one end of the rotating shaft 42 away from the connecting seat 31 is connected to a mechanical transmission claw 43. The mechanical transmission claw 43 is used to connect with the transmission claw on the driving device to drive the rotating shaft 42 to rotate through the external driving device, thereby reducing the labor intensity of the operator.

[0044] In some possible implementations, a manual turntable 44 is provided on the rotating shaft 42, and the manual turntable 44 is connected to the rotating shaft 42. The provision of the manual turntable 44 can facilitate the operator to manually rotate the rotating shaft 42. The battery module extrusion tooling of the present application supports both external device drive and manual operation, which can meet different application scenarios.

[0045] In some possible implementations, the manual turntable 44 is located between the bracket 41 and the end plate assembly 3. The manual turntable 44 and the mechanical transmission claw 43 are separated by the bracket 41. When the manual turntable 44 is manually operated, the operator is closer to the squeezed battery module, which facilitates observation of the state of the battery module.

[0046] In some possible implementations, the battery module extrusion tool includes a distance sensor (not shown), which is used to detect the length of the battery module. The battery module extrusion tool of the present application integrates force and distance testing functions.

[0047] In some possible implementations, the bracket 41 and the two end plate assemblies 3 are sequentially arranged along a straight line, and a avoidance opening 411 is provided on the bracket 41. The distance sensor is provided on the bottom plate 1 and is located on the side of the bracket 41 away from the end plate assembly 3. The detection end of the distance sensor faces the avoidance opening 411. The end plate assembly 3 close to the bracket 41 avoids the detection line of the distance sensor, and the end plate assembly 3 away from the bracket 41 is located on the detection line of the distance sensor. When the battery module is clamped by the two end plate assemblies 3, the battery module is located on the detection line of the distance sensor. One of the two end plate assemblies 3 is fixed in position during use, and the other is slidably arranged. When the rotating shaft 42 pushes into the slidable end plate assembly 3, the end assembly squeezes the battery module, so that the size of the battery module changes. The battery module is located on the detection line of the distance sensor, and the position change of the battery module can be monitored by the distance sensor. The position of the fixed end plate assembly 3 is known, so the overall length of the battery module can be determined by detecting the position of the battery module away from the fixed end assembly.

[0048] The distance sensor may be an infrared sensor, and the detection line of the distance sensor may be understood as the detection light path of the infrared sensor.

[0049] In some possible embodiments, the side panel assembly 2 includes a side panel 21, a slide plate 22 and a guide rail 23, wherein the guide rail 23 is arranged on the base plate 1, the guide rail 23 extends along a first direction, the slide plate 22 is connected to the side panel 21, the slide plate 22 is connected to the guide rail 23, and the slide plate 22 can translate along the guide rail 23 and be fixed to the base plate 1.

[0050] Specifically, the battery module extrusion tooling includes a locking mating plate 5, which is arranged on the bottom plate 1, and the locking mating plate 5 has a strip groove extending along a first direction. The side plate assembly 2 has a locking device, and the locking device includes a slider and a handle 6. The slider is connected to the locking mating plate 5, and the slider can only translate along the strip groove. The slider is provided with a threaded groove, and the handle 6 is rotatably connected to the slide plate 22. The handle 6 has a stud, and the stud is threadedly connected to the threaded groove. The handle 6 rotates forward to clamp the slide plate 22 between the handle 6 and the slider (or the slide plate 22 is clamped between the handle and the locking mating plate 5), and the slide plate 22 is fixed and cannot move anymore. The handle 6 rotates in the reverse direction, and the handle 6 and the slider (or the locking mating plate 5) can loosen the slide plate 22.

[0051] It should be noted that the slider can only slide along the strip groove of the locking matching plate 5 and cannot rotate, and the slider cannot move along the thickness direction of the locking matching plate 5. The position of the slide plate 22 can be fixed by rotating the handle 6.

[0052] In some possible embodiments, a plurality of first connection hole groups 11 are provided on the bottom plate 1, and the first connection hole groups 11 are arranged in sequence along a first direction. A second connection hole group 221 is provided on the sliding plate 22, and the second connection hole group 221 can be connected to a corresponding first connection hole group 11 through a fixing member.

[0053] The number of holes in the first connection hole group 11 is large, and the number of holes in the second connection hole is small. An operator can slide the side plate 21 to clamp the battery module. After the side plate 21 moves into place, a fastener is passed through the first connection hole group 11 and connected to the corresponding second connection hole group 221 to fix the position of the side plate 21. The fastener can be a screw, and the first connection hole group 11 on the bottom plate 1 can be a threaded hole.

[0054] In some possible embodiments, a third connection hole group is provided on the end plate assembly 3 away from the bracket 41, and a plurality of fourth connection hole groups are provided on the bottom plate 1. The fourth connection hole groups are arranged in sequence along a second direction, and the third connection hole group can be fixed to any one of the fourth connection hole groups through a fixing member.

[0055] A connector 7 can also be provided on the bottom plate 1. The connector 7 is used to connect a pressure sensor and a distance sensor. The connector 7 can be connected to a control end, and the control end can obtain the pressure monitored by the pressure sensor and the size of the battery module after being squeezed, so as to prevent damage to the battery cells caused by the extrusion force exceeding the pressure range of the battery cells and the extrusion overstroke.
