[0034] The utility model provides an arc-shaped battery bag cutting mechanism, the positioning clamping groove 111 and the pressing part 121 of feeding clamp 100 are arranged in a shape suitable for the arc-shaped battery 600, so that the feeding clamp 100 can clamp and fix the arc-shaped battery 600 and keep the shape of the arc-shaped battery 600, the cutting groove 221 and the cutting part 231 of the cutting device are arranged in a shape suitable for the arc-shaped battery 600, so that the bottom wall of the cutting groove 221 can be attached to and support the arc-shaped battery 600 in the process of cutting the air bag 610 of the arc-shaped battery 600 by cooperation of the bottom wall of the cutting groove 221 and the cutting part 231, the cutting part 231 can be attached to the inner wall of the air bag 610 of the arc-shaped battery 600 first and then cut the air bag 610 of the arc-shaped battery 600 by cooperation of the bottom wall of the cutting groove 221, so that the arc-shaped battery 600 is little deformed or not deformed in the cutting process, and therefore, the arc-shaped battery bag cutting mechanism can meet the bag cutting requirement of the arc-shaped battery 600.

[0035] Referring to Figure 1 and Figure 2According to some embodiments of the utility model, first cutting piece 220 is detachably installed in mobile assembly 210, and pressing material part 121 is detachably installed in pressing material piece 120. Upper material clamp 100 comprises first position adjusting structure 130, positioning clamp seat 110 is detachably installed in first position adjusting structure 130, and pressing material piece 120 is installed in first position adjusting structure 130. First position adjusting structure 130 is used to move and adjust the position of positioning clamp seat 110 along the third direction. Second cutting piece 230 is detachably installed in mobile assembly 210 through second position adjusting structure 240, and second position adjusting structure 240 is used to move and adjust the position of second cutting piece 230 along the third direction. The third direction is perpendicular to the first direction and the second direction. Thus, for arc-shaped batteries 600 of different sizes, the first cutting piece 220, the second cutting piece 230 and the positioning clamp seat 110 can be replaced according to the size of the arc-shaped battery 600. Then, the position of the positioning clamp seat 110 is moved and adjusted along the third direction through the first position adjusting structure 130, so that the coaxiality between the positioning clamp groove 111 and the cutting groove 221 is adjusted. The position of the second cutting piece 230 is moved and adjusted along the third direction through the second position adjusting structure 240, so that the coaxiality between the cutting part 231 and the cutting groove 221 is adjusted. Therefore, the coaxiality between the positioning clamp groove 111, the cutting groove 221 and the cutting part 231 meets the requirements, so as to ensure that the arc-shaped battery 600 of different sizes is little deformed or not deformed during the cutting process. Through the above setting, the arc-shaped battery bag cutting mechanism can meet the bag cutting demand of the arc-shaped battery 600 of different sizes.

[0036] Referring to Figure 1 And Figure 5 According to some embodiments of the utility model, first position adjusting structure 130 comprises base 131, sliding seat 132 and first locking bolt 133. Sliding seat 132 is installed in base 131, and sliding seat 132 can slide relative to base 131 along the third direction.

First locking bolt 133 is arranged in first strip-shaped hole 1321 and is screwed with base 131. Positioning clamp seat 110 is detachably installed in sliding seat 132, and pressing material piece 120 is slidably installed in sliding seat 132 along the first direction. Thus, first locking bolt 133 is loosened, and the position of sliding seat 132 is slid and adjusted along the third direction, and then the position of positioning clamp seat 110 and pressing material piece 120 is adjusted, so that the coaxiality between the positioning clamp groove 111 and the cutting groove 221 is adjusted.

[0037] The pressing piece 120 is connected with a guide column 140, the guide column 140 is slidably arranged in the sliding seat 132, the axial direction of the guide column 140 is along the first direction, thereby the pressing piece 120 can slide along the first direction. Of course, in other embodiments, the pressing piece 120 can also be slidably installed in the sliding seat 132 through a guide rail-sliding block structure.

[0038] It can be imagined that the first position adjusting structure 130 can also adopt other setting modes, for example, a lead screw can be rotatably installed on the base 131, the lead screw is screwed with a nut, and the nut is installed on the sliding seat 132, at this time, the first locking bolt 133 and the first slot 1321 can not be provided, and only by rotating the lead screw, the position of the sliding seat 132 can be slidably adjusted, and the self-locking action between the lead screw and the nut can fix the position of the sliding seat 132.

[0039] Referring to Figure 1 and Figure 6 According to some embodiments of the utility model, the second position adjusting structure 240 comprises a mounting column 241 and a second locking bolt 242, the mounting column 241 is installed on the moving assembly 210, the axial direction of the mounting column 241 is along the third direction, the mounting column 241 is arranged in the second cutting piece 230, the second cutting piece 230 can slide along the mounting column 241, and the second locking bolt 242 is screwed on the second cutting piece 230 and abuts against the mounting column 241. Thus, by loosening the second locking bolt 242, the position of the second cutting piece 230 can be slidably adjusted along the third direction, and finally the second locking bolt 242 is tightened again to fix the position of the second cutting piece 230.

[0040] During the bag cutting process, since the cutting part 231 is inserted and attached in the arc-shaped air bag 610, the cut air bag 610 can be attached on the cutting part 231, thereby affecting the bag cutting work of the next arc-shaped battery 600.

[0041] Referring to Figures 2 to 4According to some embodiments of the present application, the mounting column 241 is rotatably mounted on the moving assembly 210, the mounting column 241 is arranged at one end of the second cutting member 230 away from the first cutting member 220, the swing assembly 250 is arranged between the second cutting member 230 and the moving assembly 210, when the moving assembly 210 drives the second cutting member 230 to move away from the first cutting member 220, the swing assembly 250 can drive the second cutting member 230 to swing around the axis of the mounting column 241 to the side away from the feeding clamp 100. Thus, after the second cutting member 230 and the first cutting member 220 cooperate to complete the bag cutting work, the moving assembly 210 drives the second cutting member 230 to move away from the first cutting member 220 to a certain position, at this time, the swing assembly 250 drives the second cutting member 230 to swing around the axis of the mounting column 241 to the side away from the feeding clamp 100, so that the second cutting member 230 shakes off the cut air bag 610, thereby avoiding the cut air bag 610 adhering to the cutting part 231, and the bag cutting work of the next arc-shaped battery 600 is not affected.

[0042] With reference to Figure 2 , Figure 4 and Figure 6 , according to some embodiments of the present application, the swing assembly 250 comprises a transmission member 251 and a pushing member 252, the transmission member 251 is mounted at one end of the second cutting member 230 away from the first cutting member 220, the pushing member 252 is located on the side of the transmission member 251 away from the feeding clamp 100, the pushing member 252 is mounted on the moving assembly 210, the pushing member 252 is provided with a first abutting surface 2521 and a second abutting surface 2522, the first abutting surface 2521 is arranged along the first direction, the second abutting surface 2522 is inclined and close to the second cutting member 230, during the process that the moving assembly 210 drives the second cutting member 230 to move away from the first cutting member 220, the transmission member 251 abuts on the first abutting surface 2521 and the second abutting surface 2522 in turn, so that the second cutting member 230 swings and inclines to the side away from the feeding clamp 100 from the vertical state, during the process that the moving assembly 210 drives the second cutting member 230 to move close to the first cutting member 220, the second cutting member 230 can recover to the vertical state from the state of swinging and inclining to the side away from the feeding clamp 100 under the action of its own gravity, so that the second cutting member 230 cooperates with the first cutting member 220 to perform the bag cutting work.

[0043] It should be noted that the second position adjusting structure 240 can also adopt other setting modes, and the specific setting mode can refer to the first position adjusting structure 130, which will not be described in detail here.

[0044] It can be imagined that the swing assembly 250 described above can also be arranged in other ways, for example, the swing assembly 250 can include a telescopic air cylinder, one end of the telescopic air cylinder is rotatably connected to the moving assembly 210, and the other end is rotatably connected to the second cutting member 230, thereby, by the extension and retraction of the telescopic air cylinder, the second cutting member 230 can be driven to swing.

[0045] With reference to Figure 1 According to some embodiments of the present application, the first cutting member 220 is detachably mounted on the moving assembly 210 through the third position adjusting structure 260, the third position adjusting structure 260 is used to adjust the position of the first cutting member 220 along the second direction and the third direction, and the moving assembly 210 can drive the first cutting member 220 to move along the first direction.

[0046] With reference to Figure 1 and Figure 6 According to some embodiments of the present application, the moving assembly 210 includes a first lifting module 210a and a second lifting module 210b, the first cutting member 220 is mounted on the first lifting module 210a through the third position adjusting structure 260, and the second cutting member 230 is mounted on the second lifting module 210b through the second position adjusting structure 240, the first lifting module 210a is used to drive the first cutting member 220 to move along the first direction, and the second lifting module 210b is used to drive the second cutting member 230 to move along the first direction, thus, the first cutting member 220 and the second cutting member 230 can move independently, which is convenient for debugging.
