[0030] Referring to FIG. 1, the present application provides a sheet making device 100 and a cutting and stacking integrated machine (not shown in the figure). The cutting and stacking integrated machine includes the sheet making device 100.
[0031] The sheet making device 100 can make electrode sheets, which can be positive electrode sheets or negative electrode sheets. The cutting and stacking integrated machine generally also includes a stacking device (not shown in the figure), which can alternately stack the electrode sheets made by the sheet making device 100 with the separator to make the battery cell.
[0032] Referring to FIG. 2, the sheet making device 100 in one embodiment of the present application includes a conveying mechanism 110, a first die-cutting mechanism 120, and an adapter mechanism 130.
[0033] The conveying mechanism 110 is capable of pulling the tabbing material 20 and conveying the tabbing material 20 to the first die-cutting mechanism 120. Specifically, the conveying mechanism 110 in the embodiment adopts two clamping rollers to clamp the tabbing material 20, and one of the clamping rollers is a main drive roller. Under the drive of the main drive roller, the clamped tabbing material 20 can be conveyed to the first die-cutting mechanism 120 downstream.
[0034] The first die-cutting mechanism 120 includes a first lower die 121 and a first upper die 122. The first upper die 122 is capable of lifting and pressing relative to the first lower die 121, and the tabbing material 20 can enter between the first lower die 121 and the first upper die 122 under the conveying of the conveying mechanism 110. Moreover, the first upper die 122 can cut the tabbing material 20 into a plurality of tabs 21 each time it is pressed down.
[0035] The first lower die 121 or the first upper die 122 is pre-formed with a die-cutting plate of a required shape. When the first upper die 122 is pressed down, the tabbing material 20 can be pressed and held on the first lower die 121, and the tabbing material 20 can be cut into tabs 21 by the die-cutting plate. When the first upper die 122 is lifted, the cut tabs 21 can be left on the surface of the first lower die 121.
[0036] Specifically, in the embodiment, the surface of the first lower die 121 is provided with suction holes (not shown) that are in communication with negative pressure cavities. The suction holes can form a negative pressure on the surface of the first lower die 121 to suck the cut tabs 21, so as to avoid the tabs 21 from being adhered to the first upper die 122 and moving upward with the first upper die 122. In addition, the waste and dust generated by cutting can be sucked away through the suction holes, so as to avoid affecting the cutting precision due to the pollution of the die-cutting space.
[0037] In addition, in the embodiment, the tabbing device 100 further includes a second die-cutting mechanism 140, which is arranged upstream of the conveying mechanism 110, and the tabbing material 20 can pass through the second die-cutting mechanism 140 under the pulling of the conveying mechanism 110. The second die-cutting mechanism 140 can process tabs and round corners on the edges of the tabbing material 20, and the first upper die 122 can cut the tabbing material 20 to obtain the tabs 21 when it is pressed down.
[0038] The pole piece 21 molded by the first die-cutting mechanism 120 and the second die-cutting mechanism 140 twice includes at least one pole tab, and at least one of the corners is rounded. Preferably, all four corners are rounded. The rounded corners make the pole piece 21 have no sharp corners, which can avoid piercing the separator in the subsequent process of stacking to prepare the battery cell, thereby improving the safety of the battery cell. Further, since the pole piece 21 is molded twice, and the pole tab and the rounded corner are processed and formed by the second die-cutting mechanism 140, the die structure of the first die-cutting mechanism 120 and the second die-cutting mechanism 140 can be simplified compared with the die structure of the one-piece punching and molding, thereby helping to improve the precision of the pole piece 21 molding.
[0039] Moreover, since the degree of wear of the die is different when processing the pole tab and cutting the pole piece strip 20. Therefore, if the one-piece punching and molding die is used to process the pole tab and cut the pole piece strip 20 at the same time, it will cause uneven wear of the die, thereby making the entire die need to be replaced. By using the first die-cutting mechanism 120 and the second die-cutting mechanism 140 to realize the cutting of the pole piece strip 20 and the molding of the pole tab respectively, the dies of the first die-cutting mechanism 120 and the second die-cutting mechanism 140 can realize uniform wear during use, thereby helping to prolong the service life of the die.
[0040] In addition, when the die of any one of the first die-cutting mechanism 120 and the second die-cutting mechanism 140 is severely worn, it can be replaced or repaired alone, and the other can be used normally. Further, since the die structure of the first die-cutting mechanism 120 and the second die-cutting mechanism 140 is simpler than that of the one-piece punching, and can be repaired separately, the difficulty of die repair can also be significantly reduced.
[0041] Specifically in the embodiment, the second die-cutting mechanism 140 includes two oppositely arranged second dies 141, and the two side edges of the pole piece strip 20 in the width direction passing through the second die-cutting mechanism 140 can pass through the two second dies 141 respectively, and the distance between the two second dies 141 is adjustable.
[0042] The second die 141 is similar in structure to the first die-cutting mechanism 120, and also includes an upper die and a lower die. The two second dies 141 can cut the two edges in the width direction respectively, thereby processing the pole tab and / or the rounded corner on the two edges. Specifically, one of the second dies 141 in the embodiment is used to process the rounded corner on one side edge of the pole piece strip 20, and the other second die 141 is used to process the rounded corner on the other side edge of the pole piece strip 20 while also processing the pole tab. Moreover, by adjusting the distance between the two second dies 141, the length of the finally molded pole piece 21 can be controlled, thereby ensuring the precision of the length dimension of the pole piece 21.
[0043] Further, in the embodiment, the first upper die 122 comprises a plurality of parallel and equally spaced cutters 1221, and the first upper die 122 is capable of cutting out one pole piece 21 between any two adjacent cutters 1221 when the first upper die 122 is pressed down.
[0044] For example, the first upper die 122 shown in FIG. 1 comprises three cutters 1221, and the first upper die 122 is capable of cutting out two pole pieces 21 when the first upper die 122 is pressed down. The cutters 1221 extend along the width direction of the pole piece tape 20, and are capable of forming a plurality of cuts extending along the width direction on the pole piece tape 20 when the first upper die 122 is pressed down, and the pole pieces 21 are obtained between any two adjacent cuts. The distance between any two adjacent cuts (or the distance between any two adjacent cutters 1221) is equal to the width of the pole piece 21 obtained by cutting, and since the distance between any two adjacent cutters 1221 is determined when the first upper die 122 is pressed down each time, the consistency of the width of the pole pieces 21 obtained by cutting can be ensured.
[0045] Further, in the embodiment, the distance between the cutters 1221 is adjustable. Therefore, by adjusting the distance between the cutters 1221, the width of the pole piece 21 finally formed can be controlled, so as to ensure the accuracy of the width of the pole piece 21. Moreover, different widths of pole pieces 21 can be obtained by cutting when the distance between the cutters 1221 is different, so that the pole piece manufacturing device 100 is suitable for processing pole pieces 21 of different models.
[0046] The switching mechanism 130 comprises a discharge transfer assembly 131 and a discharge conveying assembly 132. The discharge transfer assembly 131 is capable of grabbing the pole pieces 21 on the first lower die 121 when the first upper die 122 is lifted and pressed, and transferring the plurality of pole pieces 21 obtained by one pressing of the first upper die 122 to the discharge conveying assembly 132. The discharge transfer assembly 131 can be a mechanical hand provided with a suction cup at the end, a multi-axis moving platform or a multi-axis robot, etc., and the suction cup is capable of adsorbing the pole pieces 21. The discharge conveying assembly 132 can be a vacuum belt, which is capable of adsorbing the pole pieces 21 received and conveying them downstream.
[0047] The discharge transfer assembly 131 can be avoided when the first upper die 122 is lifted, and thus the discharge transfer assembly 131 can transfer the pole pieces 21 on the first lower die 121 to the discharge conveying assembly 132 in the interval when the first upper die 122 is lifted and pressed. Therefore, the first lower die 121 can remain fixed in position, and the first upper die 122 can be alternately pressed and lifted according to the preset frequency, so as to cut the pole piece tape 20 into pole pieces 21 one by one, thereby significantly improving the manufacturing rhythm. Moreover, since a plurality of pole pieces 21 can be cut out by one pressing of the first upper die 122, a larger number of pole pieces 21 can be manufactured per unit time.
[0048] In the embodiment, the first die-cutting mechanism 120 is provided with an adapter mechanism 130 on each side, and the discharge transfer assemblies 131 of the two adapter mechanisms 130 can alternately grab the pole pieces 21 on the first lower die 121.
[0049] Since the first upper die 122 can cut multiple pole pieces 21 at one time, a single discharge transfer assembly 131 may not be able to timely take away the multiple pole pieces 21 at one time, resulting in the need to prolong the lifting time of the first upper die 122. By providing the adapter mechanism 130 on each side, the two discharge transfer assemblies 131 can alternately act, thereby quickly taking away the pole pieces 21 on the first lower die 121, which helps to further improve the piece-making rhythm.
[0050] Alternatively, a single discharge transfer assembly 131 can simultaneously grab multiple pole pieces 21. After one of the discharge transfer assemblies 131 removes the multiple pole pieces 21 obtained by one-time pressing of the first upper die 122 from the first lower die 121, the next pressing of the first upper die 122 can be performed without waiting for the discharge transfer assembly 131 to return to the first upper die 122, and multiple pole pieces 21 can be obtained. At this time, the multiple pole pieces 21 obtained by the next pressing can be transferred by the other discharge transfer assembly 131. Such a cycle also helps to further improve the rhythm of the first die-cutting mechanism 120.
[0051] In addition, in the embodiment, the adapter mechanism 130 further includes a visual detection assembly 133 for obtaining image information of the pole pieces 21 on the discharge conveying assembly 132. The visual detection assembly 133 can be a CCD camera and can be arranged above the discharge conveying assembly 132. The pole pieces 21 conveyed by the discharge conveying assembly 132 can pass through the detection range of the visual detection assembly 133 in turn. By comparing the image information obtained by the visual detection assembly 133 with reference information, it can be determined whether the pole pieces 21 have defects.
[0052] Further, the adapter mechanism 130 further includes a variable-distance transfer assembly 134, a positioning platform 135, and a discharge transfer assembly 136. The variable-distance transfer assembly 134 is used to transfer the pole pieces 21 on the discharge conveying assembly 132 to the positioning platform 135 and increase the distance between adjacent two pole pieces 21. The discharge transfer assembly 136 is used to grab the pole pieces 21 on the positioning platform 135 and discharge.
[0053] A visual module (not labeled in the figure) is arranged above the positioning platform 135 and can obtain position information of the pole pieces 21 on the positioning platform 135. The positioning platform 135 positions and corrects the pole pieces 21 according to the position information provided by the visual module, so as to ensure that the discharge transfer assembly 136 can smoothly grab the pole pieces 21 on the positioning platform 135. Specifically, the positioning platform 135 can drive the pole pieces 21 carried thereby to translate in at least two directions and rotate, so as to achieve the purpose of positioning and correcting.
[0054] The distance-changing transfer assembly 134 can grasp a plurality of pole pieces 21 at a time and place the plurality of pole pieces 21 after the distance between the pole pieces 21 is pulled apart on the positioning platform 135. Generally, the number of pole pieces 21 grasped by the distance-changing transfer assembly 134 at a time is equal to the number of pole pieces 21 obtained by each time the first upper mold 122 is pressed down. By increasing the distance between two pole pieces 21, the edges of adjacent pole pieces 21 can be prevented from interfering with each other, thereby ensuring that the vision module above the positioning platform 135 can accurately obtain the position information of the pole pieces 21.
[0055] The downline transfer assembly 136 can be a multi-axis robot, the end of which is provided with a suction cup for sucking the pole pieces 21. After the pole pieces 21 are grasped, the downline transfer assembly 136 can downfeed the pole pieces 21 to a designated position according to the detection structure of the vision detection assembly 133.
[0056] Further, in the embodiment, the pole piece manufacturing device 100 further comprises a downline conveying mechanism 150 and an NG bin 160, and the downline transfer assembly 136 can downfeed the pole pieces 21 grasped from the positioning platform 135 to the downline conveying mechanism 150 or the NG bin 160.
[0057] The downline conveying mechanism 150 can also be a vacuum belt, which can adsorb the pole pieces 21 received. Specifically, for the pole pieces 21 that pass the detection, the downline transfer assembly 136 downfeeds the pole pieces 21 to the downline conveying mechanism 150, and the downline conveying mechanism 150 conveys the pole pieces 21 to a subsequent process. For the pole pieces 21 that fail the detection, the downline transfer assembly 136 downfeeds the pole pieces 21 to the NG bin 160 for scrap processing.
[0058] Obviously, in other embodiments, for the pole pieces 21 that do not need to participate in the next process immediately, the downline transfer assembly 136 can also downfeed the pole pieces 21 grasped from the positioning platform 135 to a corresponding bin (not shown) according to different types for storage.
[0059] The above tabletting device 100 and the cutting and stacking integrated machine, the first upper die 122 can cut the polar piece material belt 20 into polar pieces 21 by pressing down relative to the first lower die 121, and the discharge transfer assembly 131 can transfer the polar pieces 21 on the first lower die 121 out of the first die cutting machine 120 in the interval of the pressing down and lifting up of the first upper die 122 relative to the first lower die 121. The first upper die 122 can avoid the discharge transfer assembly 131 when it is lifted up, so the first lower die 121 can remain fixed in position, and the first upper die 122 can cut the polar piece material belt 20 into polar pieces 21 in turn by alternating pressing down and lifting up at a predetermined frequency, thereby significantly improving the tabletting rhythm. Moreover, a plurality of polar pieces 21 can be cut at one time by pressing down the first upper die 122. Therefore, the tabletting efficiency of the above tabletting device 100 and the cutting and stacking integrated machine is significantly improved.
[0060] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.
[0061] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
