[0027] See also Figure 1 The present invention provides a slicing device 100 . The slicing device 100 includes a cutting mechanism 110 , a feeding mechanism 120 and a conveying mechanism 130 .

[0028] The inventors have noticed that as battery manufacturers place increasingly higher demands on stacking efficiency, the production efficiency of traditional production equipment has become difficult to match, and has become the main factor restricting stacking efficiency. To further improve stacking efficiency, it is necessary to first improve production efficiency. Currently, the conventional approach is to increase the feed speed of the electrode material strip and the cutting frequency of the cutter assembly. However, this will result in reduced cutting accuracy and a lower yield rate of the electrode.

[0029] Based on the above considerations, in order to further improve the production efficiency and ensure the cutting accuracy and the yield rate of the electrode pieces on this basis, the inventors designed the above-mentioned slicing device 100 after in-depth research. The slicing device 100 uses at least two cutters 111 to simultaneously perform cutting operations on the electrode material strip 200, thereby multiplying the number of electrode pieces 201 obtained per unit time. Moreover, during the cutting process, each part of the electrode material strip 200 is supported in turn by the feeding mechanism 120, the discharging assembly 112 and the conveying mechanism 130, so that the electrode material strip 200 can maintain a high stability, thereby ensuring cutting accuracy and yield rate.

[0030] The present invention also provides a laminating machine (not shown) comprising a slicing device 100. The laminating machine can be provided with one or more laminating stations. At each laminating station, a laminating robot (not shown) sequentially stacks the diaphragm sheets and the electrode sheets 201 produced by the slicing device 100 to form a battery cell. Furthermore, since the slicing device 100 achieves improved production efficiency, the laminating machine's laminating efficiency is also further enhanced.

[0031] Of course, in other embodiments, the slicing device 100 can also be used to slice other types of material strips and obtain corresponding sheets.

[0032] The cutting mechanism 110 has a cutting channel (not shown) for the electrode strip 200 to pass through. The cutting mechanism 110 includes at least two cutters 111. The at least two cutters 111 are spaced apart along the extending direction of the cutting channel. The cutters 111 can be arranged along the cutting direction, such as Figure 1 The electrode strip 200 passing through the cutting channel is cut back and forth in the up and down directions shown in the figure, thereby cutting off the electrode strip 200 and obtaining the electrode 201. When performing the cutting operation, at least two cutters 111 cut the electrode strip 200 into at least two electrode pieces 201. For example, Figure 1 The cutting mechanism 100 shown is equipped with two cutters 111, so a single cutting operation can produce two pole pieces 201. The cutting mechanism 110 is generally also equipped with a knife holder opposite the cutters 111, with the cutter 111 and the knife holder forming the aforementioned cutting channel. During the cutting operation, the cutters 111 cooperate with the knife holder to smoothly sever the pole piece strip 200.

[0033] The feeding mechanism 120 is disposed upstream of the cutting mechanism 110, and the conveying mechanism 130 is disposed downstream of the cutting mechanism 110. The upstream and downstream positions of the cutting mechanism 110 are relative to the conveying direction of the electrode strip 200. For example, if the electrode strip 200 passes through the cutting mechanism 110 from left to right, the feeding mechanism 120 is disposed on the left side of the cutting mechanism 110, and the conveying mechanism 130 is disposed on the right side of the cutting mechanism 110. In addition, to ensure the stability of the relative positions of the cutting mechanism 110, the feeding mechanism 120, and the conveying mechanism 130, the slicing device 100 further includes a base 140, on which the cutting mechanism 110, the feeding mechanism 120, and the conveying mechanism 130 are all mounted.

[0034] The feeding mechanism 120 can support and drive the electrode material strip 200 into the cutting channel. After the electrode material strip 200 is cut by the cutting mechanism 110 in the previous cutting operation, its end can be supported by the feeding mechanism 120, which can provide driving force for the end of the electrode material strip 200, thereby driving the electrode material strip 200 to re-enter the cutting channel of the cutting mechanism 110 to prepare for the next cutting.

[0035] Specifically in this embodiment, the feeding mechanism 120 includes two feed rollers capable of clamping the pole piece strip 200, and at least one feed roller is connected to a power element (not shown). The feed roller connected to the power element serves as the main drive roller and can provide driving force for the pole piece strip 200. Since the pole piece strip 200 is clamped by the two feed rollers during the conveying process, it can prevent the pole piece strip 200 from slipping relative to the feeding mechanism 120 during the conveying process, thereby improving the feeding accuracy of the pole piece strip 200, and further helping to improve the accuracy of the produced pole piece 201.

[0036] The conveying mechanism 130 is capable of carrying the electrode strip 200 passing through the cutting channel. In other words, the two ends of the electrode strip 200 outside the cutting mechanism 110 can be supported by the feeding mechanism 120 and the conveying mechanism 130 respectively. When performing the cutting operation, at least two cutters 111 cut the electrode strip 200 into at least two electrode pieces 201. Among them, one electrode piece 201 is carried on the conveying structure 130, and the remaining electrode pieces 201 are located between two adjacent cutters 111. For example, if two cutters 111 are provided, the cutting mechanism 110 can obtain two electrode pieces 201 by performing one cutting operation.

[0037] Furthermore, the cutting mechanism 110 also includes a discharge assembly 112 disposed between two adjacent cutters 111. The number of discharge assemblies 112 is related to the number of cutters 111. For example, if two cutters 111 are provided, one discharge assembly 112 is provided. The discharge assembly 112 is capable of supporting and driving the electrode strip 200 between two adjacent cutters 111 to be transported downstream.

[0038] The discharge assembly 112 can employ a similar structure to the feed mechanism 120. Specifically, the discharge assembly 112 includes two opposing discharge rollers capable of clamping the electrode strip 200, one of which is connected to a power element. As the electrode strip 200 passes through the cutting channel, the discharge assembly 112 cooperates with the feed mechanism 120 to pull the electrode strip 200. This prevents excessive stretching or wrinkling of the electrode strip 200, thereby facilitating control of the feeding accuracy of the electrode strip 200.

[0039] Moreover, after the cutting mechanism 110 performs a cutting operation, the electrode piece 201 located between two adjacent cutters 111 is sequentially transferred from the discharge assembly 112 to the conveying mechanism 130 , and finally transferred to a designated position by the conveying mechanism 130 .

[0040] Specifically in this embodiment, the carrying surface of the conveying mechanism 130 can absorb the carried electrode strip 200. Before performing the operation, the carrying surface of the conveying mechanism 130 can absorb the end of the electrode strip 200, thereby better restraining the electrode strip 200, preventing wrinkles in the electrode strip 200, and further improving the cutting accuracy. After cutting is completed, during the process of moving the electrode 201, the carrying surface of the conveying mechanism 130 can also absorb the electrode 201, thereby preventing the electrode 201 from scattering.

[0041] More specifically, the conveying mechanism 130 includes a conveying roller and a vacuum belt sleeved on the conveying roller. The surface of the vacuum belt can form a negative pressure to absorb the electrode strip 200 and the electrode 201 .

[0042] In this embodiment, the cutting mechanism 110 further includes a cutting drive assembly 113 and a mounting block 114. At least two cutters 111 are mounted on the mounting block 114, and the cutting drive assembly 113 is in transmission connection with the mounting block 114. The cutting drive assembly 113 can be driven by a pneumatic cylinder or a motor, driving the mounting block 114 to reciprocate along the cutting direction, thereby driving the at least two cutters 111 to perform cutting synchronously. This indicates that mounting the at least two cutters 111 on the same mounting block 114 enhances synchronization between the different cutters 111.

[0043] In this embodiment, the cutting mechanism 110 further includes an adjustment component 115, which can adjust the distance between two adjacent cutters 111. By adjusting the distance between two adjacent cutters 111, the width of the cut electrode 201 can be changed, thereby making the slicing device 100 compatible with electrode processing of various sizes.

[0044] Furthermore, in this embodiment, the adjustment assembly 115 includes a fixed block 1151, an adjustment screw 1152, and a sliding block 1153. The sliding block 1153 is capable of sliding along the extension direction of the cutting channel. Specifically, the sliding block 1153 is mounted on the base 140 via a slider. The adjustment screw 1152 is rotatably mounted on the fixed block 1151 and is threadedly connected to the sliding block 1153. At least a portion of the cutter 111 can slide along the extension direction of the cutting channel under the drive of the sliding block 1153.

[0045] The sliding block 1153 may include an internal thread or a threaded seat for threaded engagement with the adjusting screw 1152. Rotating the adjusting screw 1152 causes the sliding block 1153 to slide along the direction of the cutting path, thereby causing at least some of the cutters 111 to slide along the direction of the cutting path, thereby adjusting the distance between two adjacent cutters 111. Furthermore, the high feed accuracy of the adjusting screw 1152 improves the accuracy of distance adjustment, thereby ensuring the precision of the width of the cut pole piece 201.

[0046] Taking the case of two cutters 111 as an example, one of the cutters 111 is fixed in position, while the other cutter 111, which needs to slide, is connected to the sliding block 1153. The cutter 111, which needs to slide, can be slidably mounted on the mounting block 114 along the extension direction of the cutting channel via a connecting block 116. The connecting block 116 is in transmission connection with the sliding block 1153, and the connecting block 116 and the sliding block 1153 have a degree of freedom along the cutting direction and can move relative to each other. Specifically, the connecting block 116 and the sliding block 1153 can be connected by a connecting rod (not shown) extending along the cutting direction. One end of the connecting rod is fixed to the sliding block 1153, and the other end is movable through a through hole on the connecting rod. In this way, the sliding block 1153 can drive the connecting block 116 to slide along the extension direction of the cutting channel through the connecting rod. When the cutting mechanism 110 performs the cutting operation, the connecting block 116 can move along the cutting direction relative to the sliding block 1153, thereby preventing the sliding block 1153 from limiting the movement of the cutter 111.

[0047] More specifically, in this embodiment, the sliding block 1153 and the fixed block 1151 are located on the side of the cutting channel opposite the cutter 111, and a knife holder that cooperates with the cutter 111 is provided on the top wall of the sliding block 1153 and / or the fixed block 1151 facing the cutter 111. This eliminates the need for an additional knife holder, thereby simplifying the structure of the slicing device 100.

[0048] Please also refer to Figure 2 In this embodiment, the cutting mechanism 110 also includes a downward pressing component 117 linked to the cutter 111. The downward pressing component 117 includes a pressing plate 1171 and an elastic support member 1172. The distance between the pressing plate 1171 and the knife seat is smaller than the distance between the cutter 111 and the knife seat, and the pressing plate 1171 can overcome the elastic force of the elastic support member 1172 under the support of the knife seat so that the cutter 111 extends toward the knife seat relative to the pressing plate 1171.

[0049] The pressing assembly 117 can be mounted on the mounting block 114 and can move synchronously with the cutter 111. In the initial state, supported by the elastic support member 1172, the distance between the pressing plate 1171 and the cutter holder is smaller than the distance between the cutter 111 and the cutter holder. Therefore, when the cutter 111 performs the cutting operation, the pressing plate 1171 can abut against the cutter holder before the cutter 111, thereby pressing the electrode strip 200 in the cutting channel against the cutter holder. As the cutter 111 continues to move toward the cutter holder, the pressing plate 1171 will overcome the elastic force of the elastic support member 1172 under the support of the cutter holder and the elastic support member 1172 will be compressed, while the cutter 111 gradually extends toward the cutter holder relative to the pressing plate 1171 until it cooperates with the cutter holder to cut the electrode strip 200. It can be seen that before the cutter 111 cuts the pole piece strip 200 , the pressing plate 1171 can press and fix the pole piece strip 200 , thereby maintaining the position of the pole piece strip 200 stable and the surface flat during the cutting process, further improving the cutting accuracy.

[0050] Specifically, the elastic support member 1172 may be a spring, an elastic pad, or a spring. Specifically, in this embodiment, the pressing assembly 117 further includes a guide rod 1173 extending in the cutting direction. The guide rod 1173 is slidably mounted on the mounting block 114 in the cutting direction, and the pressing plate 1171 is fixedly connected to the end of the guide rod 1173 away from the mounting block 114. In this case, the elastic support member 1172 may be a spring, which is sleeved on the guide rod 1173 and abuts against the pressing plate 1171.

[0051] Furthermore, in this embodiment, a pressing assembly 117 is provided corresponding to each cutter 111, and the pressing assembly 117 is located upstream of the corresponding cutter 111. Thus, before the cutter 111 cuts the electrode strip 200, each area to be cut can be held in place by the pressing plate 1171, thereby further maintaining the stability of the electrode strip 200.

[0052] In the above-mentioned slicing device 100 and laminating machine, the electrode material strip 200 can pass through the cutting channel under the drive of the feeding mechanism 120 and be carried by the conveying mechanism 130. When the cutting mechanism 110 performs the cutting operation, at least two cutters 111 can cut the electrode material strip 200 passing through the cutting channel into multiple electrode pieces 201. Among them, the electrode piece 201 between two adjacent cutters 111 is transported to the conveying mechanism 130 by the discharge component 112, and the conveying mechanism 130 can transport the carried electrode piece 201 downstream. During the process of performing the cutting operation on the electrode material strip 200, the electrode material strip 200 is supported by the feeding mechanism 120, the discharge component 112 and the conveying mechanism 130 in turn, so that it can maintain a high stability, thereby ensuring the accuracy of the simultaneous cutting of at least two cutters 111. Since the cutting mechanism 110 can obtain at least two electrode pieces 201 in one cutting, the production efficiency of the above-mentioned slicing device 100 and laminating machine is significantly improved.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
