[0038] Example 1

[0039] This embodiment provides a pole piece gluing mechanism 10, such as Figure 1-5 As shown, a pole piece gluing mechanism 10 includes a gluing module 1 and a cutting module 2, wherein the gluing module 1 is arranged on one side of the cutting module 2; the cutting module 2 includes:

[0040] The pressing assembly 210 includes a first driving member 21, and a pressing member 212 is connected to the first driving member 21 to drive the pressing member 212 to reciprocate along a first direction to press the pole piece;

[0041] The winding assembly 220 includes a winding roller 221, a pressing roller 222, a second driving member 223 and a third driving member 224; the second driving member 223 is connected to the winding roller 221 to drive the second driving member 223 to rotate; the third driving member 224 is connected to the pressing roller 222 to drive the pressing roller 222 to move closer to or away from the winding roller 221;

[0042] The slitting assembly 230 is disposed between the pressing assembly 210 and the winding assembly 220. The slitting assembly 230 includes a first moving assembly 231 disposed along the second direction. A cutter 232 is disposed on the first moving end of the first moving assembly 231. The first direction is perpendicular to the second direction.

[0043] Specifically, for the sake of convenience, this embodiment introduces a mounting frame, the second direction is along the width direction of the pole piece, the first direction and the second direction are perpendicular to each other, and an opening is provided on the mounting frame to facilitate the pole piece at the tail of the coil 20 to enter the pole piece gluing mechanism 10. The gluing module 1 is installed at the top of the mounting frame, and the gluing module 1 is used to perform gluing on the end of the coil 20 to prevent the pole piece from expanding, and the cutting module 2 is arranged at the bottom of the gluing module 1.

[0044] Among them, the pressing component 210 presses the pole piece to keep it relatively fixed, so that the subsequent cutter 232 can cut the pole piece. The first driving member 21 can be a cylinder, a screw, etc., and this embodiment does not make specific restrictions, as long as it can drive the clamping member 212 to clamp the pole piece. Exemplarily, the clamping member 212 is plate-shaped, and preferably, its length is greater than or equal to the width of the pole piece. During use, the cylinder drives the clamping member 212 to move until it abuts against the pole piece and clamps it. During the clamping process, the clamping member 212 can cooperate with the side plate on the mounting frame to fix the pole piece; of course, it can also be two pressing components 210, driving the two clamping members 212 to move relative to each other, so as to clamp and fix the pole piece.

[0045] The winding assembly 220 is used to collect the waste electrode pieces after cutting. The winding assembly 220 is arranged below the pressing assembly 210. The winding roller 221 and the pressing roller 222 are arranged opposite to each other. Under normal circumstances, there is a gap between the two to facilitate the entry of the electrode piece. One end of the winding roller 221 is connected to the second driving member 223, which can be a motor, and the motor is used to drive the winding roller 221 to rotate; the pressing roller 222 is provided with a third driving member 224, which can be a cylinder, a screw guide rail, etc., and its purpose is to drive the pressing roller 222 to move relative to the winding roller 221. When the electrode piece does not enter, the third driving member 224 drives the pressing roller 222 away from the winding roller 221 to leave a channel. When the electrode piece enters the channel, the third driving member 224 drives the pressing roller 222 to move toward the winding roller 221 until the electrode piece abuts against the winding roller 221.

[0046] Exemplarily, a waste bin may be provided at the bottom of the winding assembly 220 to collect waste electrodes. A plurality of winding rollers 221 may be provided, and the plurality of winding rollers 221 are arranged in parallel to facilitate the electrodes to enter the waste bin and keep the workstation tidy.

[0047] The slitting assembly 230 is arranged between the winding assembly 220 and the pressing assembly 210. The first moving assembly 231 is along the width direction of the pole piece. The first moving assembly 231 can be a transmission system composed of a screw guide rail, a gear rack, a transmission belt and a transmission wheel, etc., which is not specifically limited in this embodiment. Exemplarily, the first moving assembly 231 of this embodiment is a transverse movement module, and the cutter 232 is arranged at the moving end of the transverse movement module.

[0048] During use, the coil 20 is first reversed. At this time, the end of the pole piece enters the first frame, the pressing assembly 210 presses the pole piece, and the third driving member 224 drives the pressing roller 222 to move toward the winding roller 221, pressing the pole piece against the winding roller 221, and the cutter 232 moves along the width direction of the pole piece to cut the pole piece. After cutting, the winding roller 221 rotates to roll the waste pole piece into a cylinder; the gluing module 1 glues the coil 20 after cutting.

[0049] By setting up the pressing component 210 and the winding component 220, the electrode sheet can be pressed and put into a stretched state. The cutter 232 component cuts the electrode sheet, which improves the stability of the electrode sheet cutting process and ensures that the electrode sheet is flat after cutting. Setting the gluing module 1 and the cutting module 2 together can improve the automation level of the equipment and reduce labor costs. At the same time, the winding component 220 can recycle the waste electrode sheet by setting the winding roller 221 and the pressing roller 222 to ensure the cleanliness of the work station.

[0050] In some embodiments of the present application, the gluing module 1 includes a transverse gluing component 110, which is movably arranged on the first moving end of the first moving component 231, and the transverse gluing component 110 is arranged opposite to the cutter 232. By arranging the transverse gluing module 1 to bond the cut pole pieces together, it is convenient for the automatic tape splicing in the subsequent rolling process. The transverse gluing module 1 and the cutter 232 components are arranged on the first moving component 231 at the same time, which can save the manufacturing cost of the equipment.

[0051] Furthermore, the transverse gluing component 110 includes a second movable component 111, and a transverse gluing head 112 is movably provided on the second movable end of the second movable component 111, so that the transverse gluing head 112 can move along the first direction. Among them, the second movable component 111 can make the transverse gluing module 1 move relative to the coil 20, further improving the success rate of gluing. The second movable component 111 can be a screw guide rail, a cylinder, a gear rack, etc., and this embodiment does not make specific limitations. Exemplarily, the second movable component 111 includes a guide rail and a cylinder, and the transverse gluing head 112 is movably provided on the guide rail, and the output end of the cylinder is movably connected to the transverse gluing head 112, and the transverse gluing head 112 is driven by the cylinder to move toward the direction of the pole piece coil 20.

[0052] In some embodiments of the present application, the gluing module 1 includes a longitudinal gluing component 122, which is movably disposed on the first moving end of the first moving component 231, and the longitudinal gluing component 122 is disposed opposite to the cutter 232. The longitudinal gluing component 122 is used to apply longitudinal glue to the tail of the coil 20, and the number of gluing is at least two, and the longitudinal glue strips can prevent the pole piece from expanding during transportation.

[0053] Further, the longitudinal gluing component 122 includes a third movable component 121, and a longitudinal gluing head 122 is movably provided on the third movable end of the third movable component 121, so that the longitudinal gluing head 122 can move along the first direction. The third movable component 121 can be a screw guide rail, a cylinder, a gear rack, etc., and this embodiment does not make specific limitations. Exemplarily, the third movable component 121 includes a guide rail and a cylinder, and the longitudinal gluing head 122 is movably provided on the guide rail. The output end of the cylinder is movably connected to the longitudinal gluing head 122, and the longitudinal gluing head 122 is driven by the cylinder to move in the direction of the pole piece coil 20. It can be understood that the transverse gluing head 112 and the longitudinal gluing head 122 can be provided on the same side of the first movable component 231, and they can also be separately provided on the first movable component 231.

[0054] In some embodiments, the cutting module 2 further includes a color mark sensor for detecting the electrode piece. The color mark sensor is used to detect whether the waste electrode piece has been moved into place, thereby improving the success rate of cutting.

[0055] Example 2

[0056] Example 2 is similar to Example 1, as Figure 7 As shown, further, a sampling component 240 is also provided between the pressing component 210 and the winding component 220, and the sampling component 240 includes a fourth moving component 241, and a suction member 242 is provided on the fourth moving end of the fourth moving component 241, so that the fourth moving component 241 drives the suction member 242 to move along the second direction. The sampling component 240 is used to extract the pole piece to facilitate the subsequent detection of the pole piece. Among them, the fourth moving component 241 can be a screw guide rail, a cylinder, or a gear rack. In this embodiment, the fourth moving component 241 is a transverse movement module. When the suction component absorbs the pole piece, the pole piece is driven to move by the transverse movement module, and the pole piece is placed in a fixed position to wait for subsequent detection.

[0057] During use, after the waste electrode is cut off, the coil 20 continues to reverse, so that the electrode enters the electrode gluing mechanism 10, and the electrode is vertically moved to a certain distance. The pressing component 210 presses one end of the electrode, and the suction piece 242 absorbs the other end of the electrode. At this time, the cutter 232 moves to cut the electrode, and then the suction piece 242 moves the electrode to a fixed position under the drive of the fourth moving component 241.

[0058] Furthermore, the suction member 242 is a suction cup, which sucks the pole piece, moves it to a fixed position, and then blows back to place the pole piece.

The gluing equipment is provided with a moving module 30, which can drive the material roll and the electrode gluing mechanism 10 to move relative to each other, so that the electrode automatically enters the gluing mechanism for slitting, gluing and other processes without manual participation, further improving production efficiency.
