[0056] The present application provides a winding core tab cutting device, comprising:

[0057] Base 100;

[0058] The flip lifting mechanism 200 is provided with a clamping mechanism 210, which is used to clamp the winding core 300. The flip lifting mechanism 200 is used to drive the clamping mechanism 210 to move in the Z-axis direction and to drive the clamping mechanism 210 to rotate around an axis, so that the winding core can move in the Z-axis direction and rotate around the axis by a set angle; wherein the axis is perpendicular to the Z-axis direction;

[0060] A positioning mechanism 500, the positioning mechanism 500 is disposed on the base 100, the displacement mechanism 400 is disposed below the positioning mechanism 500, and the positioning mechanism 500 has a working state and a non-working state: when the positioning mechanism 500 is in the working state, the positioning mechanism 500 clamps the winding core 300 at the positioning position; when the positioning mechanism 500 is in the non-working state, the positioning mechanism 500 releases the winding core 300; and

[0061] The cutting mechanism 600 is disposed on the base 100 and is disposed downstream of the displacement mechanism 400 along the X-axis direction. The cutting mechanism 600 cuts the core 300 at the cutting position.

[0062] See also Figure 1 , Figure 1The overall structural schematic diagram of the winding core tab cutting device in one embodiment of the present application is shown. The winding core tab cutting device provided in one embodiment of the present application includes a base 100, which is used to provide a storage space for other components. A flip lifting mechanism 200 is provided on the flip lifting mechanism 200, and the clamping mechanism 210 is used to clamp the winding core 300. The flip lifting mechanism 200 is used to drive the clamping mechanism 210 to move in the Z-axis direction and drive the clamping mechanism 210 to rotate around an axis, so that the winding core can move in the Z-axis direction and rotate around the axis to a set angle; wherein the axis is perpendicular to the Z-axis direction. After the clamping mechanism 210 clamps the winding core 300, the flip lifting mechanism 200 can drive the winding core 300 to rotate a set angle, which is usually 180°, and then the winding core 300 can also be moved in the Z-axis direction, that is, the flip lifting mechanism 200 can adjust the winding core 300 in the height direction and can also rotate to adjust the position of the winding core 300.

[0063] The displacement mechanism 400 is disposed on the base 100, and the flip lifting mechanism 200 is movably disposed on the displacement mechanism 400. The displacement mechanism 400 is used to drive the flip lifting mechanism 200 to move along the X-axis direction. In order to achieve the position of the core 300 being moved in the X-axis direction and to move the core 300 to a specified position, the flip lifting mechanism 200 is slidably connected to the displacement mechanism 400, and the displacement mechanism 400 can drive the flip lifting mechanism 200 to move in the X-axis direction, thereby driving the core 300 to move in the X-axis direction.

[0064] The positioning mechanism 500 is arranged on the base 100, and the displacement mechanism 400 is arranged below the positioning mechanism 500. The positioning mechanism 500 is used to clamp the winding core 300 to realize the positioning of the winding core 300. The positioning mechanism 500 has a working state and a non-working state: when the positioning mechanism 500 is in the working state, the positioning mechanism 500 clamps the winding core 300 at the positioning position, and the winding core 300 can be positioned at the positioning position; when the positioning mechanism 500 is in the non-working state, the positioning mechanism 500 releases the winding core 300, and at this time, the winding core 300 can be separated from the positioning mechanism 500 under the drive of the flip lifting mechanism 200.

[0065] The cutting mechanism 600 is disposed on the base 100 and at the end of the displacement mechanism 400 . The cutting mechanism 600 cuts the winding core 300 at the cutting position.

[0066] Combination Figure 2 As shown, Figure 2The overall structural diagram of the flip lifting mechanism, displacement mechanism, positioning mechanism and cutting mechanism in an embodiment of the present application is shown. In the prior art, the tabs cut twice on the front and back sides are mainly single-sided tabs. This is because if the single-sided tab is not rotated 180°, the tabs will not be cut in place, and there will be too much remaining length after the tabs are cut, which will cause abnormal subsequent unwinding. During the working process, the flip lifting mechanism 200 first moves to the positioning position along the X-axis direction, clamps the winding core 300 on the clamping mechanism 210, and the positioning mechanism 500 will be in a non-working state. Then the flip lifting mechanism 200 is continued to be driven by the displacement mechanism 400 to reach the cutting position. At the cutting position, the cutting mechanism 600 cuts the tabs of the winding core 300, and then the flip lifting mechanism 200 retreats along the X-axis direction, and the flip lifting mechanism 200 drives the winding core 300 to rotate 180°. Then the flip lifting mechanism 200 continues to move to the cutting position, and at the cutting position, the cutting mechanism 600 cuts the tabs again.

[0067] Through the configuration of the above-mentioned flipping and lifting mechanism 200, displacement mechanism 400, positioning mechanism 500 and cutting mechanism 600, the winding core tab cutting device in the present application can perform double-sided cutting of the tab, can be compatible with different winding cores 300, and ensure cutting of tabs of sufficient length.

[0068] In addition, it also includes a loading mechanism 700, which is arranged on the base 100. The loading mechanism 700 includes a loading pull belt 710 and a loading robot 720. The loading pull belt 710 is used to move the core 300 to the loading position, and the loading robot 720 is used to move the core 300 from the loading position to the positioning position. The loading mechanism 700 in the present application includes a loading pull belt 710 and a loading robot 720. The loading pull belt 710 moves the core 300 from one end of the base 100 to the loading position. After the loading position, the loading robot 720 starts to work and moves the core 300 from the loading position to the positioning position, that is, the position where the positioning mechanism 500 is located.

[0069] See also Figure 4 , Figure 4 The overall structure diagram of the flip lifting mechanism in one embodiment of the present application. The flip lifting mechanism 200 includes a fixing frame 220, a first driving member 230 and a second driving member 240;

[0070] The clamping mechanism 210 is disposed on the upper side of the fixing frame 220 , and the clamping mechanism 210 is used to clamp the winding core 300 ;

[0071] The fixed frame 220 is also provided with a first driving member 230 and a second driving member 240, which are respectively connected to the clamping mechanism 210; in the flip position, the first driving member 230 is used to drive the clamping mechanism 210 to rotate a set angle; the second driving member 240 is used to drive the clamping mechanism 210 to move along the Z-axis direction. The clamping mechanism 210 in the present application clamps the winding core 300 on the upper side of the fixed frame 220, and then the first driving member 230 is connected to the clamping mechanism 210. The first driving member 230 can drive the clamping mechanism 210 to rotate a set angle around the X-axis direction. The set angle in this embodiment is 180°, that is, in the flip position, the other side of the winding core 300 is flipped to an upward position. The second driving member 240 is also connected to the clamping mechanism 210 , and can drive the winding core 300 in the clamping mechanism 210 to rise or fall. The rising or falling of the winding core 300 can drive the winding core 300 to fall on or leave the positioning mechanism 500 .

[0072] In one embodiment of the present application, the height of the positioning position is smaller than the height of the cutting position, and the height of the flipping position is equal to the height of the cutting position.

[0073] Specifically, the displacement mechanism 400 includes a displacement drive and a linear guide rail, and the displacement drive is used to drive the flip lifting mechanism 200 to move on the linear guide rail. In the present application, the displacement mechanism 400 includes a drive and a linear guide rail, and the flip lifting mechanism 200 is slidably connected to the linear guide rail, so that the displacement drive drives the flip lifting mechanism 200 to move on the linear guide rail along the X-axis direction.

[0074] For details about the positioning mechanism 500, see Figure 3 , Figure 3 Schematic diagram of the overall structure of the positioning mechanism in one embodiment of the present application. The positioning mechanism 500 includes a first positioning portion 510 and a second positioning portion 520; the first positioning portion 510 is used to abut the end of the core 300, and the second positioning portion 520 is used to clamp the two sides of the core 300. The first positioning portion 510 includes a first positioning drive member and an abutment member. When the core 300 is placed on the positioning mechanism 500, the first positioning drive member can drive the abutment member to move, so that the abutment member abuts against the end of the core 300 to achieve positioning of the end of the core 300. The second positioning portion 520 includes a second positioning drive member and a clamping plate, and the clamping plate is arranged on both sides of the positioning mechanism 500. When the core 300 is placed on the positioning mechanism 500, the second positioning drive member can drive the clamping plate to move, so that the clamping plate clamps the two sides of the core 300.

[0075] In one embodiment, the cutting mechanism 600 includes: a frame 610; a cutting cylinder 620, which is arranged on the frame 610; and a cutting knife 630, which is used to drive the cutting knife 630 to move along the Z-axis direction and cut the core 300. The frame 610 is arranged at the end of the displacement mechanism 400, and the displacement mechanism 400 can drive the flipping and lifting mechanism 200 to move to the position where the cutting mechanism 600 is located. After moving to the cutting mechanism 600, the core 300 will extend into the cutting knife 630, and the cutting cylinder 620 will then drive the cutting knife 630 to move downward along the Z-axis direction, thereby cutting off the tab of the core 300.

[0076] Further, two cutters 630 are provided, the two cutters 630 are arranged at intervals, and the cutting cylinder 620 drives the two cutters 630 to move along the Z-axis direction. The cutters 630 in one embodiment of the present application are provided with two left and right cutters, and the two cutters 630 are arranged at intervals. By providing two cutters 630, the two cutters 630 can be used to cut the positive and negative tabs respectively, which can effectively avoid the safety risks caused by the short circuit of the positive and negative tabs.

[0077] Moreover, in one embodiment of the present application, a placement platform 800 is further included, and the placement platform 800 is arranged on the base 100, and the displacement mechanism 400 is arranged below the placement platform 800, and the placement platform 800 is used to store the core 300 after the tabs are cut. The placement platform 800 in one embodiment of the present application includes a bracket and a flat plate, and the bracket is used to support the flat plate, and the bracket is connected to the base 100. After the tabs of the core are cut, the loading robot 720 can be used to temporarily place the core 300 on the placement platform 800 as a temporary storage platform for the core 300. And the height of the placement platform 800 is greater than the height of the flip lifting mechanism 200, so that the flip lifting mechanism 200 can move in the space under the placement platform 800.

[0078] In addition, a blanking mechanism is also included, which is arranged on the base 100 and is used to accommodate the cut pole lugs. The blanking mechanism is a box-shaped structure, which is arranged directly below the cutting mechanism 600, with an opening facing the cutting mechanism 600, so that the cut pole lugs can fall into the blanking mechanism, which is convenient for subsequent processing of the cut pole lugs.

[0079] The present application also provides a winding core tab cutting method, using the winding core tab cutting device as described above, comprising the following steps:

[0080] S1: The winding core 300 is moved to a positioning position by the loading mechanism 700;

[0081] S2: At the positioning position, the positioning mechanism 500 is controlled to clamp the winding core 300;

[0082] S3: Control the flipping and lifting mechanism 200 to move to the positioning position, control the clamping mechanism to clamp the winding core 300, and then control the flipping and lifting mechanism 200 to move to the cutting position;

[0083] S4: After the cutting mechanism 600 cuts the pole ear at one end of the winding core 300 at the cutting position, the flipping and lifting mechanism 200 is controlled to clamp the winding core 300 and continue to move to the flipping position;

[0084] S5: After controlling the flipping and lifting mechanism 200 to drive the winding core 300 to rotate to a set angle, the flipping and lifting mechanism 200 is controlled to continue to move to a cutting position;

[0085] S6: After the cutting mechanism 600 is controlled to cut the other end of the pole ear of the winding core 300, the flipping and lifting mechanism 200 is controlled to clamp the winding core 300 and continue to move to the positioning position;

[0086] S7: Control the positioning mechanism 500 to release, and control the feeding mechanism 700 to move the winding core 300 to a designated position.

[0087] Using the above method, the winding core tab cutting device can cut the tab twice, so that different winding cores can be cut, avoiding the remaining tab length being too long due to one cutting, thereby avoiding unwinding abnormalities.

[0088] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
