In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.
[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] The following describes a repair tool 1 for a battery cell carrier according to an embodiment of the present utility model with reference to the accompanying drawings.
[0030] like Figure 1-Figure 3 As shown, the cell carrier 2 has a cell support notch 3 , which is suitable for accommodating the cell. The edge of the cell support notch 3 is provided with a cell support step 4 , and the cell is suitable for being supported on the cell support step 4 .
[0031] Specifically, the cell needs to be placed on the cell carrier 2 during the coating process. The cell carrier 2 adopts a hollow structure and has a cell support notch 3. The edge of the cell support notch 3 has a cell support step 4 to support the cell. The cell support step 4 is prone to deformation during use, resulting in the cell support step 4 not being able to fit tightly with the cell and a gap. In this way, the conductive film layer will extend into the gap during coating, resulting in poor coating of the cell.
[0032] In the related art, if the support plate step 4 is deformed, it needs to be returned to the factory for reprocessing or repaired by hammering. The return to the factory for reprocessing takes a long time and is costly. The repair accuracy of hammering is poor, it is difficult to guarantee the repair effect, and it is easy to cause destructive damage.
[0033] The repairing tool 1 for the battery cell carrier according to the embodiment of the utility model comprises a first correction plate 10, a second correction plate 20 and an extrusion drive mechanism.
[0034] The first correction plate 10 and the second correction plate 20 are suitable for jointly clamping the support plate step 4. The extrusion drive mechanism is respectively connected to the first correction plate 10 and the second correction plate 20 to jointly press the support plate step 4 to correct the deformed support plate step 4.
[0035] Specifically, when the support step 4 is deformed, the first correction plate 10 and the second correction plate 20 are used to clamp the support step 4, and then the extrusion drive mechanism is operated to extrude the support step 4 using the first correction plate 10 and the second correction plate 20 to correct the deformed support step 4 and restore the support step 4 to be flat, so that the battery cell can remain in contact with the support step 4 without generating gaps.
[0036] According to the repair tool 1 for the battery cell carrier of the embodiment of the utility model, by setting the first correction plate 10 and the second correction plate 20, the first correction plate 10 and the second correction plate 20 can be used to clamp the support step 4, and the extrusion driving mechanism is used to provide an extrusion driving force to prompt the first correction plate 10 and the second correction plate 20 to clamp the support step 4, correct the deformed support step 4, reshape the support step 4, restore the support step 4 to be flat, and enable the battery cell to fit with the support step 4, avoid the generation of a gap between the battery cell and the support step 4, avoid the conductive film layer extending into the gap, and improve the coating reliability of the battery cell.
[0037] Moreover, compared with the repair method of returning to the factory for reprocessing in the related art, only the repair tool 1 of the battery cell carrier needs to be used for repair, and there is no need to disassemble the battery cell carrier 2. The repair operation is more convenient, and there is no need to reprocess the battery cell carrier 2. The repair cycle can be shortened and the repair cost can be reduced. Compared with the hammer repair method used in the related art, the flatness is easier to ensure through the clamping and extrusion correction method, the repair effect is better, and it is less likely to cause destructive damage, making the repair work more reliable.
[0038] Therefore, the repair tool 1 for the battery cell carrier according to the embodiment of the utility model has the advantages of convenient operation, short repair cycle, low repair cost, good repair effect, etc.
[0039] The following describes a repair tool 1 for a battery cell carrier according to a specific embodiment of the present utility model with reference to the accompanying drawings.
[0040] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the repair tool 1 for the battery cell carrier according to the embodiment of the utility model includes a first correction plate 10, a second correction plate 20 and an extrusion drive mechanism.
[0041] Specifically, Figure 1-Figure 6 As shown, the extrusion drive mechanism includes a tension plate 30, a screw rod 40 and a rotating handle 50. The tension plate 30 is provided with a threaded hole 31, and the tension plate 30 is located on the side of the second correction plate 20 away from the first correction plate 10. The first correction plate 10 is provided with a first through hole 11, and the second correction plate 20 is provided with a second through hole 21. The screw rod 40 can detachably pass through the first through hole 11 and the second through hole 21 and can detachably thread with the threaded hole 31. The screw rod 40 is provided with a stopper 41, and the stopper 41 stops on the side of the first correction plate 10 away from the second correction plate 20. The rotating handle 50 is connected to the screw rod 40.
[0042] Specifically, when it is necessary to repair the support step 4, firstly, the first correction plate 10 and the second correction plate 20 are matched at the corresponding support notch 3, and the support step 4 is clamped by the first correction plate 10 and the second correction plate 20, and then the screw 40 is passed through the first through hole 11 and the second through hole 21 and matched in the threaded hole 31, and then the rotating handle 50 is turned, and the threaded match between the screw 40 and the threaded hole 31 is used to convert the rotation of the screw 40 into the movement of the tension plate 30 along the axial direction of the screw 40, so that the stop table 41 and the tension plate 30 drive the first correction plate 10 and the second correction plate 20 to press the support step 4 against each other, and correct the deformed support step 4. After the repair is completed, the screw 40 can be detached from the threaded hole 31, the first through hole 11 and the second through hole 21, so as to realize the disassembly of the repair tool 1 of the battery cell carrier.
[0043] In this way, an extrusion driving force can be provided for the first correction plate 10 and the second correction plate 20 to correct the support step 4. Moreover, since the tension plate 30 is independent of the second correction plate 20, the torsional force of the screw 40 can be prevented from directly acting on the second correction plate 20, thereby preventing the second correction plate 20 from rotating and affecting the correction effect of the support step 4.
[0044] In addition, by detachably engaging the screw 40 in the first through hole 11, the second through hole 21 and the screw 40, the disassembly and assembly of the battery cell carrier repair tool 1 can be achieved. On the one hand, it can facilitate the repair of the support step 4 of the support slot 3 in the middle of the battery cell carrier 2, and facilitate the repair of the bracket on the battery cell carrier 2 without disassembling the battery cell carrier 2, thereby shortening the repair cycle. On the other hand, the battery cell carrier repair tool 1 can be disassembled when not needed, so as to facilitate the storage of the battery cell carrier repair tool 1, and the disassembly and assembly are simple and convenient, which can facilitate improving the repair efficiency.
[0045] Advantageously, if Figure 2-Figure 5As shown, the repair tool 1 for the battery cell carrier also includes an anti-stuck ring 60, which is sleeved outside the screw 40 and located between the first correction plate 10 and the stopper 41. Specifically, the surface of the anti-stuck ring 60 is smoothed. This can prevent the screw 40 from being stuck after being over-tightened, making it difficult to loosen the rotating handle 50.
[0046] More advantageously, if Figure 2-Figure 5 As shown, the first correction plate 10 has an arch seat 12 on one side surface away from the second correction plate 20, and a third through hole is provided on the arch seat 12. The screw rod 40 is adapted to be detachably passed through the third through hole, and the diameter of the third through hole is smaller than the diameter of the stop platform 41. In this way, the stop platform 41 can be stopped on the arch seat 12, so that the force of the stop platform 41 can be transmitted through the arch seat 12 when the screw rod 40 is tightened, so as to avoid the force of the stop platform 41 directly acting on the first correction plate 10, and thus prevent the first correction plate 10 from being deformed and affecting the repair effect.
[0047] More specifically, Figure 4 As shown, the second correction plate 20 has a groove 22 on one side of the surface away from the first correction plate 10, and at least a portion of the tension plate 30 fits in the groove 22. In this way, the tension plate 30 can be positioned by using the groove 22 during assembly, which facilitates the assembly of the repair tool 1 for the battery cell carrier.
[0048] Furthermore, if Figure 2-Figure 5 As shown, the thickness of the middle part of the tension plate 30 is greater than the thickness of the two ends. Specifically, the threaded hole 31 is provided in the middle part of the tension plate 30. In this way, the tension plate 30 is not easily deformed, and the tension plate 30 is convenient for evenly transmitting the force to the second correction plate 20, thereby ensuring the repair effect.
[0049] Optionally, the rotating handle 50 is a torque wrench. In this way, a predetermined torque can be set on the torque wrench during repair to avoid insufficient tightening that affects the repair effect, and to avoid excessive tightening that causes damage to the support step 4 or the repair tool 1 of the battery cell carrier.
[0050] Figure 3-Figure 6 The figure shows a repair tool 1 for a battery cell carrier according to some examples of the present invention. Figure 3-Figure 6As shown, the repair tool 1 for the battery cell carrier also includes a thickness adjustment label 70, which is located between the first correction plate 10 and the second correction plate 20 and is suitable for supporting the first correction plate 10 and the second correction plate 20 when the first correction plate 10 and the second correction plate 20 clamp the support plate step 4. Specifically, thickness adjustment labels 70 of different thicknesses can be selected according to the edge thickness of the support plate step 4 to be corrected. In this way, the first correction plate 10 and the second correction plate 20 can be supported by the thickness adjustment label 70 during extrusion to prevent the second correction plate 20 and the first correction plate 10 from excessively extruding the support plate step 4, which causes the edge thickness of the support plate step 4 to change, and facilitates the shaping of the support plate step 4 to avoid the inability to reliably fit the battery cell due to uneven thickness.
[0051] Specifically, Figure 3-Figure 6 As shown, the first correction plate 10 has a first boss 13 on one side of the surface facing the second correction plate 20, and the second correction plate 20 has a second boss 23 on one side of the surface facing the first correction plate 10. The first boss 13 and the second boss 23 are suitable for jointly clamping the support step 4. In this way, the first boss 13 and the second boss 23 can be used to squeeze the support step 4, which further facilitates the application of force to the support step 4 and improves the repair effect of the support step 4.
[0052] More specifically, Figure 3-Figure 6 As shown, the circumference of the first boss 13 is at a right angle to the table surface of the first boss 13, and the circumference of the second boss 23 is at an obtuse angle to the table surface of the second boss 23. Since one side of the support step 4 is a plane and the other side is an inclined surface to facilitate supporting the battery cell, by making the circumference of the first boss 13 at a right angle to the table surface of the first boss 13 and the circumference of the second boss 23 at an obtuse angle to the table surface of the second boss 23, the support step 4 can be easily shaped and repaired.
