Among them, Figure 2 is Figure 1 is a schematic structural view of the battery cell blanking device 100 from bottom to top, Figure 1 and Figure 2 in which arrow a is the first direction and arrow b is the second direction.

[0042] AsFigures 1-5 As shown in the utility model one specific embodiment, the electric core blanking device 100 can include the first clamp rod 10 and the second clamp rod 20, the first clamp rod 10 and the second clamp rod 20 all extend along the first direction, the first clamp rod 10 and the second clamp rod 20 all include fixed end and free end, the first clamp rod 10 is controlledly reciprocated along the second direction to approach or away from the second clamp rod 20. Wherein, the first direction is perpendicular to the second direction. The electric core blanking device 100 can also include driving mechanism 30 and resistance piece 40. Wherein, one end of resistance piece 40 is connected with driving mechanism 30 to rotate under the driving of driving mechanism 30, and the other end is provided with resistance part 41 to make resistance part 41 abut or away from the free end of the second clamp rod 20.

[0043] Here, it can be understood that before the first clamp rod 10 and the second clamp rod 20 clamp the electric core, resistance piece 40 is rotated to the position away from the free end of the second clamp rod 20 to avoid resistance piece 40 hindering the first clamp rod 10 and the second clamp rod 20 clamping the electric core. When the first clamp rod 10 is controlled to move close to the second clamp rod 20, the first clamp rod 10 and the second clamp rod 20 clamp the electric core, and the needle is separated from the electric core to realize the electric core blanking.

[0044] Before operating the first clamp rod 10 to move towards the direction close to the second clamp rod 20, resistance piece 40 is rotated to abut the free end of the second clamp rod 20, then the first clamp rod 10 is moved, and then the first clamp rod 10 and the second clamp rod 20 clamp the electric core. The abutment of the resistance part 41 of resistance piece 40 and the free end of the second clamp rod 20 can effectively reduce the force of the first clamp rod 10 and the electric core on the second clamp rod 20, and avoid the free end of the second clamp rod 20 from being easily bent under stress.

[0045] The electric core blanking device 100 of the utility model embodiment adds resistance piece 40 and driving mechanism 30, when resistance piece 40 is driven by driving mechanism 30 to move away from the free end of the second clamp rod 20, the first clamp rod 10 and the second clamp rod 20 can clamp the electric core without obstruction, when resistance piece 40 is driven by driving mechanism 30 to abut the free end of the second clamp rod 20, resistance part 41 can assist in fixing the second clamp rod 20, avoid the second clamp rod 20 from sliding and tilting when the electric core is blanked, further avoid the electric core from being damaged by sliding, and also make the clamping force uniform when the first clamp rod 10 and the second clamp rod 20 clamp the electric core, effectively reduce the deformation of the clamp rod when working.

[0046] In some embodiments, the driving mechanism 30 can comprise a moving rod 31 extending along the first direction, one end of the moving rod 31 being connected with the resisting piece 40 and being arranged to rotate when moving along the first direction, thereby driving the resisting piece 40 to rotate. It can be understood that the extending direction of the moving rod 31 is the same as the extending direction of the first clamping rod 10 and the second clamping rod 20, so as to facilitate the arrangement of the driving mechanism 30, reduce the occupied space of the battery cell unloading device 100, and improve the space utilization. The use of the moving rod 31 can make the rotation of the resisting piece 40 more stable, thereby improving the stability of the battery cell unloading device 100.

[0047] Figure 6 is a schematic structural view of the sleeve piece 32 according to one specific embodiment of the present utility model, Figure 7 is a schematic sectional view of the sleeve piece 32 according to one specific embodiment of the present utility model. As Figure 6 and Figure 7 indicated, and referring to Figure 1 In some embodiments, the driving mechanism 30 can further comprise a sleeve piece 32 extending along the first direction, and the moving rod 31 is arranged in the sleeve piece 32 and rotates under the limitation of the sleeve piece 32.

[0048] It can be understood that the extending direction of the sleeve piece 32 is the same as the extending direction of the moving rod 31, and the moving rod 31 is arranged in the sleeve piece 32, and the sleeve piece 32 is fixed. When the moving rod 31 moves along the first direction, the moving rod 31 rotates while moving linearly under the limitation of the sleeve piece 32, thereby driving the resisting piece 40 to rotate, so that the resisting piece 40 is away from or abuts against the free end of the second clamping rod 20. In this way, the stability of the rotation of the resisting piece 40 can be improved, so that the resisting part 41 can be stably rotated to the position away from or abutting against the free end of the second clamping rod 20.

[0049] Figure 8 is a schematic structural view of the cam 33 according to one specific embodiment of the present utility model. In some embodiments, as Figure 8 indicated, and referring to Figure 2 The surface of the sleeve piece 32 can be provided with an opening 321 arranged at least partially in a spiral along the surface of the sleeve piece 32. The surface of the moving rod 31 is provided with a cam 33, and when the moving rod 31 is arranged in the sleeve piece 32, the cam 33 cooperates with the opening 321 of the sleeve piece 32, thereby making the moving rod 31 rotate under the limitation of the opening 321 while moving along the first direction.

[0050] In some embodiments, the opening 321 is composed of a part arranged along the first direction and a part arranged spirally along the surface of the sleeve 32. When the moving rod 31 moves along the first direction, the cam 33 on the surface of the moving rod 31 cooperates with the spiral opening 321, and under the limit of the part of the opening 321, the moving rod 31 rotates, so that the moving rod 31 can rotate while moving linearly, and the moving rod 31 can drive the stopper 40 to rotate, so that the stopper 41 can abut against or be away from the free end of the second clamping rod 20.

[0051] In some embodiments, the driving mechanism 30 can further include a first driving member 34 connected with the moving rod 31 to drive the moving rod 31 to move along the first direction. In some embodiments, the first driving member 34 can be a pneumatic cylinder. In other embodiments, the first driving member 34 can be other driving mechanisms 30 with driving functions, such as a motor.

[0052] In some embodiments, the driving mechanism 30 can further include a bearing member 35 connected between the first driving member 34 and the moving rod 31 to enable the moving rod 31 to rotate relative to the first driving member 34. The bearing member 35, as a support and transmission element, is arranged between the moving rod 31 and the first driving member 34. When the first driving member 34 drives the moving rod 31 to move, the bearing member 35 can support the moving rod 31 to ensure that the moving rod 31 rotates stably, thereby improving the stability and reliability of the battery cell unloading device 100.

[0053] In some embodiments, the bearing member 35 is a knuckle bearing. The knuckle bearing can provide good support and help support the weight of the moving rod 31. By providing stable support, the knuckle bearing can also reduce the frictional resistance of the moving rod 31, thereby improving the operating efficiency of the battery cell unloading device 100.

[0054] In some embodiments, referring to Figure 1 , the first direction a is the left-right direction, and the second direction b is the front-back direction. Before the battery cell unloading device 100 is used for unloading, the position state of the moving rod 31 and the stopper 40 is as shown in Figure 5 , the moving rod 31 moves to the leftmost end, and the stopper 41 of the stopper 40 is away from the free end of the second clamping rod 20, so that the stopper 40 can avoid interfering with the first clamping rod 10 and the second clamping rod 20 to clamp the battery cell.

[0055] When the power cell blanking device 100 is used for blanking, the first clamping rod 10 and the second clamping rod 20 first clamp the power cell, and then the first driving member 34 moves the moving rod 31 to the right, and the moving rod 31 rotates under the limiting action of the sleeve member 32. In this way, the moving rod 31 drives the blocking member 40 to move linearly to the right while driving the blocking member 40 to rotate, so that the blocking portion 41 of the blocking member 40 can abut against the free end of the second clamping rod 20.

[0056] Referring to Figure 5 and Figure 6 , the opening 321 on the side of the sleeve member 32 away from the blocking member 40 is linear, so that even if the moving rod 31 continues to move to the right, the moving rod 31 will not rotate again, that is, the blocking member 40 will not rotate again, and the blocking portion 41 can be maintained at the position abutting against the free end of the second clamping rod 20. In this way, the blocking portion 41 can stably abut against the free end of the second clamping rod 20, so that the position of the free end of the second clamping rod 20 is fixed, effectively avoiding deformation of the second clamping rod 20 under stress, and the stability of the power cell blanking device 100 can be improved.

[0057] In some embodiments, the power cell blanking device 100 can further include a second driving member 50 extending in the second direction to drive the first clamping rod 10 to move in the second direction. In some embodiments, the second driving member 50 can be a pneumatic cylinder. In other embodiments, the second driving member 50 can be other mechanisms with driving function, such as a motor.

[0058] In some embodiments, the power cell blanking device 100 can further include a guide member 60 extending in the second direction to guide the movement of the first clamping rod 10 in the second direction.

[0059] In some embodiments, the guide member 60 is a guide rail that can guide the movement of the first clamping rod 10 in the second direction, thereby improving the accuracy and stability of the movement of the first clamping rod 10 in the second direction.

[0060] In some embodiments, the blocking portion 41 can include at least one protrusion 411, so that when the blocking member 40 moves to abut against the second clamping rod 20, the at least one protrusion 411 is located on the side of the free end of the second clamping rod 20 away from the first clamping rod 10.

[0061] In some embodiments, referring to Figure 5 , the number of protrusions 411 is one, and the protrusion 411 is located at the end of the blocking portion 41.

[0062] In other embodiments, the number of protrusions 411 can be multiple, and the multiple protrusions 411 are arranged in the first direction, which can disperse the stress of the blocking member 40 and improve the stability of the power cell blanking device 100.

[0063] In some embodiments, the resisting piece 40 is L-shaped. One end of the L-shaped resisting piece 40 is connected with the moving rod 31, and the other end can be rotated to a position away from or abutting against the free end of the second clamping rod 20 under the driving of the moving rod 31. In this way, the arrangement space of the battery cell unloading device 100 can be reduced, and the practicability of the battery cell unloading device 100 can be improved.

[0064] The L-shaped resisting piece 40 has two vertical supporting points, and when subjected to external force, the stress can be effectively dispersed, and the strength and stability of the resisting piece 40 can be effectively improved. In other embodiments, the shape of the resisting piece 40 can be set according to actual needs, for example, a straight line type.

[0065] At this point, those skilled in the art should recognize that although the present application has been shown and described in detail in this paper, many other variants or modifications conforming to the principles of the present application can be directly determined or deduced according to the content disclosed in the present application without departing from the spirit and scope of the present application.
