DETAILED DESCRIPTION

[0046] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0047] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0048] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0049] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] like Figure 1-Figure 9 As shown, according to the first aspect of an embodiment of the present application, a traction and adsorption mechanism 100 is provided, comprising a traction and adsorption component 1 and a support member 2, wherein the traction and adsorption component 1 comprises an adsorption cavity 11, wherein the adsorption cavity 11 comprises a first end face 111, and wherein a negative pressure cavity 113 is provided in the adsorption cavity 11; wherein the support member 2 is installed in the adsorption cavity 11, wherein the support member 2 at least partially protrudes from the first end face 111 of the adsorption cavity 11; wherein the adsorption cavity 11 comprises a second end face 112, wherein the first end face 111 intersects with the second end face 112, wherein the support member 2 comprises a supporting surface 21, wherein the orientation of the supporting surface 21 is the same as that of the second end face 112, wherein a first through hole 23 is provided in the supporting surface 21, and wherein the first through hole 23 is connected to the negative pressure cavity 113.

[0052] The traction and adsorption mechanism 100 of the present application is mainly used to adsorb the pole piece 200 to be cut, can provide support for the pole ear during cutting, and can move the pole piece 200 during the process of cutting the pole ear or after cutting a pole ear to ensure the continuity of the pole ear cutting and the smoothness of the movement of the pole piece 200.

[0053] The traction and adsorption mechanism 100 of the present application can also be used in other foil cutting equipment to transfer the foil and provide support during cutting.

[0054] The present application takes cutting the pole piece 200 to form the pole ear as an example for explanation. The pole piece 200 includes a main body, waste material and a pole ear. After the waste material on the pole piece is cut off, the pole ear will be formed on the pole piece.

[0055] like Figure 1 and Figure 2 As shown, the traction and adsorption mechanism 100 includes a traction and adsorption component 1 and a support member 2 .

[0056] The traction adsorption assembly 1 includes an adsorption cavity 11, and the adsorption cavity 11 includes a first end face 111 and a second end face 112. The first end face 111 and the second end face 112 are oriented in different directions, the first end face 111 intersects with the second end face 112, the first end face 111 is close to the cutting area, and the adsorption belt on the second end face 112 is used to carry the pole piece 200; a negative pressure cavity 113 is opened in the adsorption cavity 11, and the pole piece 200 is kept stable on the adsorption belt located on the second end face 112 by the negative pressure cavity 113 to ensure the stability of the pole piece 200 during movement.

[0057] The support member 2 is installed on the adsorption chamber 11, and the support member 2 can be installed on the first end face 111 or the second end face 112. Since the first end face 111 is close to the cutting area, and the support member 2 protrudes from the first end face 111, that is, the support member 2 extends toward the cutting area. The support member 2 includes a support surface 21, and the support surface 21 is oriented in the same direction as the second end face 112, and the pole ear contacts the support surface 21 of the support member 2; when the pole ear is not supported during cutting, it will shake or tilt, resulting in the problem of being out of the laser focal depth, so the support member 2 provides support for the pole ear to prevent the pole ear from shaking or tilting during cutting, so as to improve the cutting quality.

[0058] A first through hole 23 is provided on the support surface 21, and the first through hole 23 is connected to the negative pressure chamber 113, which can provide sufficient adsorption force to the pole ear so that the pole ear fits on the support surface 21, and provides sufficient support for the position of the pole ear that is prone to instability during the cutting process, so that the pole ear of the pole piece 200 will not shake or tilt during the tape cutting process. Optionally, the length of the support member 2 protruding from the first end face 111 is less than the length of the waste material, so the support member 2 will only be laser ablated once in a single cutting cycle of the pole ear, and the generated dust can be sucked into the negative pressure chamber 113 through the first through hole 23 to reduce additional ablation dust, thereby maintaining the cleanliness of the cutting environment of the pole piece 200.

[0059] The traction adsorption mechanism 100 provided in the present application can realize the function of transferring the pole piece 200 through the traction adsorption component 1 to realize continuous cutting and improve work efficiency. The support member 2 is arranged on the adsorption cavity 11 to support the pole ear to prevent the pole ear from shaking or tilting during cutting, and can adsorb the generated dust into the negative pressure cavity 113 through the negative pressure cavity 113 and the first through hole 23 to maintain the cutting environment of the pole piece 200. Therefore, the traction adsorption mechanism 100 provided in the present application can not only improve work efficiency but also improve the cutting quality of the pole ear.

[0060] In an optional implementation, a mounting hole 114 is formed on the first end surface 111 , and the support member 2 includes a mounting portion 22 , and the mounting portion 22 is detachably mounted on the mounting hole 114 .

[0061] like Figure 5 and Figure 7 As shown, a mounting hole 114 is provided at the first end surface 111 near the second end surface 112, and the support member 2 includes a mounting portion 22, which is detachably mounted in the mounting hole 114, so that the support member 2 can be detachably mounted on the adsorption chamber 11. During the tab cutting process, the support member 2 will be ablated by the laser, and the support member 2 can be replaced regularly to ensure the smoothness of the support surface 21 of the support member 2.

[0062] To further illustrate, the mounting portion 22 may be a column with a rectangular cross section, and the mounting hole 114 may have a rectangular cross section, so the mounting portion 22 may be inserted into the mounting hole 114 to allow the support member 2 to be mounted together with the adsorption chamber 11 .

[0063] To further illustrate, the mounting portion 22 may also be a column with a triangular or pentagonal cross section, and the cross section of the mounting hole 114 is the same as the cross section of the mounting portion 22 , so that the support member 2 and the adsorption chamber 11 are mounted together.

[0064] When the support member 2 needs to be removed and replaced, it is only necessary to pull the mounting portion 22 out of the mounting hole 114. In addition, the mounting portion 22 is a non-smooth column, which can prevent the mounting portion 22 and the mounting hole 114 from rotating.

[0065] The mounting portion 22 can be selected as required.

[0066] like Fig.10 and Fig.11 As shown, in an optional embodiment, a second through hole 24 connected to the mounting hole 114 is opened on the mounting portion 22, and the first through hole 23 and the second through hole 24 form an air flow channel 25; the negative pressure chamber 113 is connected to the mounting hole 114, and the air flow channel 25 is connected to the negative pressure chamber 113.

[0067] like Figure 7 As shown, the mounting hole 114 extends to the negative pressure chamber 113, so that the mounting hole 114 is connected with the negative pressure chamber 113. A second through hole 24 is provided on the mounting portion 22, and the second through hole 24 is located in the mounting hole 114, so the second through hole 23 is connected with the negative pressure chamber 113, and an air flow channel 25 is provided inside the support member 2, one end of the air flow channel 25 is the second through hole 24, and the other end is the first through hole 23, so the first through hole 23 is connected with the negative pressure chamber 113 through the air flow channel 25. The tab is fitted with the support surface 21 of the support member 2, and the negative pressure chamber 113 provides adsorption negative pressure to the tab on the support surface 21 of the support member 2 through the first through hole 23, the air flow channel 25 and the second through hole 24.

[0068] In an optional embodiment, the support member may be in an inverted U-shape or an L-shape.

[0069] In an optional embodiment, the traction adsorption assembly 1 further includes an adsorption belt, which is sleeved on the adsorption cavity 11. The adsorption cavity 11 has an area not covered by the adsorption belt, and the support member 2 is arranged in the area and close to the adsorption belt. When the pole piece 200 is cut, the pole ear is adsorbed by the support member 2, and the main body of the pole piece 200 is located on the first adsorption belt 12. In this embodiment, the structure is simple, but when the pole piece 200 is transferred by the adsorption belt after being cut, the pole ear cannot be located on the adsorption belt, which will cause the pole ear to shake.

[0070] In another optional embodiment, the traction and adsorption assembly 1 also includes a first adsorption belt 12 and a second adsorption belt 13, the first adsorption belt 12 is sleeved on the adsorption cavity 11, the first adsorption belt 12 is provided with a first adsorption hole 121 connected to the negative pressure cavity 113; the second adsorption belt 13 is provided with a second adsorption hole 131 connected to the negative pressure cavity 113, the second adsorption belt 13 is spaced apart from the first adsorption belt 12 and has the same moving direction, the second adsorption belt 13 is sleeved on the adsorption cavity 11, and the support member 2 is located between the first adsorption belt 12 and the second adsorption belt 13.

[0071] like Figure 4 As shown, the traction adsorption assembly 1 also includes a first adsorption belt 12 and a second adsorption belt 13. The first adsorption belt 12 is sleeved on the adsorption cavity 11 and covers a portion of the first end face 111 and the second end face 112, and the first adsorption belt 12 can circulate around the outer end face of the adsorption cavity 11; the second adsorption belt 13 is sleeved on the adsorption cavity 11 and covers a portion of the first end face 111 and the second end face 112, and the second adsorption belt 13 can also circulate around the outer end face of the adsorption cavity 11; the second adsorption belt 13 is spaced apart from the first adsorption belt 12, and the moving direction of the second adsorption belt 13 is the same as the moving direction of the first adsorption belt 12, which can also be understood as the first adsorption belt 12 and the second adsorption belt 13 move synchronously. The support member 2 is located between the first adsorption belt 12 and the second adsorption belt 13; in this embodiment, after the pole ear is cut, at least part of the pole ear will be located on the second adsorption belt 13, and the main body of the pole piece 200 will be located on the first adsorption belt 12. When the pole piece 200 moves, the stability of the movement of the pole piece 200 can be improved to avoid shaking of the pole ear.

[0072] In an alternative embodiment, Figure 5As shown, a plurality of first air holes 116 connected to the negative pressure chamber 113 are provided on the second end surface 112, and a plurality of first adsorption holes 121 are provided on the first adsorption belt 12, and the first adsorption holes 121 are connected to the negative pressure chamber 113 through the corresponding first air holes 116, so that the electrode piece 200 located on the first adsorption belt 12 is attached to the first adsorption belt 12 through the negative pressure chamber 113; a plurality of second adsorption holes 131 are provided on the second adsorption belt 13, and the second adsorption holes 131 are connected to the negative pressure chamber 113 through the corresponding first air holes 116, so that the electrode ear located on the second adsorption belt 13 is attached to the second adsorption belt 13 through the negative pressure chamber 113; therefore, the negative pressure generated by the negative pressure chamber 113 on the inner side of the first adsorption belt 12 and the second adsorption belt 13 sucking air through the first air holes 116 provides adsorption force to the main body and the electrode ear of the electrode piece 200, so as to prevent the electrode piece 200 from shaking or jittering during cutting or moving.

[0073] In an alternative embodiment, Figure 5 As shown, a plurality of second air vents 117 connected to the negative pressure chamber 113 are provided on the first end surface 111. When the first adsorption belt 12 and the second adsorption belt 13 rotate, on the first end surface 111, the negative pressure chamber 113 absorbs air through the second air vents 117 to provide adsorption force for the dust on the first adsorption belt 12 and the second adsorption belt 13, so as to absorb the dust into the negative pressure chamber 113.

[0074] In an alternative embodiment, Figure 4 As shown, the support surface 21 is flush with the first adsorption belt 12 and the second adsorption belt 13 located on the second end surface 112 .

[0075] To further illustrate, the support surface 21 and the second end surface 112 are oriented in the same direction, the support surface 21 is flush with the upper surface of the first adsorption belt 12 located on the second end surface 112, the support surface 21 is flush with the upper surface of the second adsorption belt 13 located on the second end surface 112, and the upper surface of the first adsorption belt 12 is flush with the upper surface of the second adsorption belt 13. Therefore, when the pole piece 200 is moving, the support surface 21, the first adsorption belt 12 and the second adsorption belt 13 are flush, which can prevent the pole piece 200 from shaking or breaking due to height difference.

[0076] Flush means basically flush, and errors allowed during mechanical assembly may occur, but the errors will not affect the movement of the pole piece 200 and will not cause damage to the pole piece 200.

[0077] In an alternative embodiment, Figure 4-Figure 7As shown, the traction and adsorption assembly 1 also includes a first drive roller 14 and a plurality of second drive rollers 15, the first drive roller 14 and the plurality of second drive rollers 15 are arranged in the adsorption chamber 11, the first adsorption belt 12 is sleeved on the first drive roller 14 and the plurality of second drive rollers 15, and the second adsorption belt 13 is sleeved on the first drive roller 14 and the plurality of second drive rollers 15.

[0078] like Figure 1 As shown, the traction adsorption assembly 1 also includes a first drive roller 14 and a plurality of second drive rollers 15, and the first drive roller 14 and the plurality of second drive rollers 15 are both arranged on the adsorption chamber 11, and the first adsorption belt 12 is sleeved on the first drive roller 14 and the plurality of second drive rollers 15 so that the first adsorption belt 12 can rotate, and the second adsorption belt 13 is also sleeved on the first drive roller 14 and the plurality of second drive rollers 15, so that the first adsorption belt 12 and the second adsorption belt 13 can rotate synchronously.

[0079] In a specific embodiment, Figure 8 As shown, the traction adsorption mechanism 100 also includes a driving mechanism. The adsorption chamber 11 is a cube. A first transmission roller 14 and three second transmission rollers 15 are provided on four parallel sides. The first adsorption belt 12 and the second adsorption belt 13 are both mounted on the first transmission roller 14 and the second transmission roller 15. One of the second transmission rollers 15 is an active roller. The driving end of the driving mechanism is connected to the active roller. The driving mechanism drives the active roller to rotate, thereby causing the first adsorption belt 12 and the second adsorption belt 13 to rotate in a circular manner.

[0080] In a specific embodiment, Fig. 9 As shown, the traction adsorption mechanism 100 also includes a third transmission roller 16 and a driving mechanism. The third transmission roller 16 is an active roller. The third transmission roller 16 adsorbs the side of the cavity 11 away from the second end face 112. The adsorption cavity 11 is a cube. On four parallel sides, a first transmission roller 14 is provided on the side formed by the intersection of the first end face 111 and the second end face 112, and two second transmission rollers 15 are provided on two sides adjacent to and parallel to the intersection. The first adsorption belt 12 and the second adsorption belt 13 are sleeved on the first transmission roller 14, the third transmission roller 16 and the two second transmission rollers 15. The driving end of the driving mechanism is connected to the third transmission roller 16, and the driving mechanism drives the third transmission roller 16 to rotate, thereby causing the first adsorption belt 12 and the second adsorption belt 13 to rotate in a circular manner.

[0081] The above two implementation modes can be selected as needed.

[0082] In an optional embodiment, a receiving groove 115 is formed at one end of the first end face 111 close to the second end face 112 and one end of the second end face 112 close to the first end face 111, the first transmission roller 14 is arranged inside the receiving groove 115, the support member 2 is provided with a notch 26, the first transmission roller 14 is located in the notch 26, and the support member 2 is at least partially accommodated in the receiving groove 115.

[0083] like Figure 5 As shown, an L-shaped receiving groove 115 is formed at the intersection of the first end surface 111 and the second end surface 112, and the first transmission roller 14 is arranged in the receiving groove 115, so as to reduce the volume of the traction adsorption mechanism 1. In addition, the support member 2 is at least partially received in the receiving groove 115, and the receiving groove 115 can provide an escape space for the installation of the support member 2.

[0084] In an alternative embodiment, Figure 4 As shown, the first transmission roller 14 is arranged between the first end surface 111 and the second end surface 112, and an annular groove 143 is provided on the first transmission roller 14. One end of the annular groove 143 is provided with a first transmission part 141, and the other end is provided with a second transmission part 142. The first adsorption belt 12 is located at the first transmission part 141, and the second adsorption belt 13 is located at the second transmission part 142. The support member 2 is installed on the adsorption chamber 11 at the annular groove 143.

[0085] like Fig.12 and Fig.13 As shown, the first transmission roller 14 includes a mounting shaft 144, a first transmission part 141 and a second transmission part 142. The first transmission part 141 and the second transmission part 142 both include a bearing 1411 and a sleeve 1412. The inner ring of the bearing 1411 is sleeved on the mounting shaft 144, the sleeve 1412 is sleeved on the outer ring of the bearing 1411, the first adsorption belt 12 and the second adsorption belt 13 are sleeved on the sleeve 1412, and the mounting shaft 144 is connected to the adsorption chamber 11. When the first adsorption belt 12 and the second adsorption belt 13 rotate, the sleeve 1412 will rotate, but the mounting shaft 144 will not rotate. There is an annular groove 143 between the first transmission part 141 and the second transmission part 142. In other words, the first transmission part 141 and the second transmission part 142 are spaced apart on the mounting shaft 144, and the gap between the first transmission part 141 and the second transmission part 142 is the annular groove 143.

[0086] Further explanation: the first suction belt 12 is located at the first transmission part 141, and the second suction belt 13 is located at the second transmission part 142. When the first transmission roller 14 rotates, the first transmission part 141 and the second transmission part 142 rotate together, so the first suction belt 12 and the second suction belt 13 are driven to rotate together. A notch 26 is provided on the support member 2, and the support member 2 is arranged at the annular groove 143. The installation shaft 144 is located in the notch 26. Since the diameter of the installation shaft 144 is smaller than the diameter of the first transmission part 141 and the second transmission part 142, when the support member 2 is installed, the first transmission roller 14 can be prevented from affecting the installation of the support member 2.

[0087] like Figure 5 and Figure 6 As shown, in an optional embodiment, the traction and adsorption mechanism 100 further includes a plurality of partitions 17 , and the plurality of partitions 17 are respectively disposed on a plurality of end surfaces of the adsorption chamber 11 and are located between the first adsorption belt 12 and the second adsorption belt 13 .

[0088] like Figure 1 As shown, the traction adsorption mechanism 100 further includes a plurality of partitions 17. The plurality of partitions 17 are respectively arranged on different end surfaces of the adsorption chamber 11 and are located between the first adsorption belt 12 and the second adsorption belt 13 to separate the first adsorption belt 12 and the second adsorption belt 13 to prevent the first adsorption belt 12 and the second adsorption belt 13 from being offset during movement.

[0089] like Figure 8 In the illustrated embodiment, the traction and adsorption mechanism 100 includes four partitions 17 , which are respectively disposed on the first end surface 111 , the end surface opposite to the first end surface 111 , the second end surface 112 , and the end surface opposite to the second end surface 112 .

[0090] In such Fig. 9 In the illustrated embodiment, the traction and adsorption mechanism 100 includes three partitions 17 , and the three partitions 17 are respectively arranged on the first end surface 111 , the second end surface 112 , and the end surface opposite to the second end surface 112 .

[0091] In a preferred embodiment, the partition 17 located on the second end face 112, the end of which is close to the first end face 111 is flush with the bottom surface of the accommodating groove 115 located on the second end face 112; the partition 17 located on the first end face 111, the end of which is close to the first end face 111 is arranged adjacent to the mounting hole 114; after the mounting portion 22 of the support member 2 is installed with the mounting hole 114, one end face of the support member 2 will conflict with the end face of the partition 17 on the first end face 111, and the other end face of the support member 2 will conflict with the end face of the partition 17 on the second end face 112. The partition 17 on the first end face 111 and the partition 17 on the second end face 112 will limit the installation of the support member 2, thereby facilitating the installation of the support member 2.

[0092] In an alternative embodiment, Figure 5 As shown, the partition 17 located at the second end surface 112 is provided with an air hole 171, and the air hole 171 is connected to the negative pressure chamber 113. The dust generated by ablation of the support member 2 when cutting the tab can be sucked into the negative pressure chamber 113 through the air hole 171, reducing the dust retained on the support member 2.

[0093] In an alternative embodiment, Figure 2 As shown, the width of the support surface 21 is smaller than the width of the partition 17 located on the second end surface 112 .

[0094] The width of the support surface 21 can be understood as the size of the support surface 21 in a direction perpendicular to the moving direction of the first adsorption belt 12 .

[0095] The width of the separator 17 can be understood as the size of the separator 17 in a direction perpendicular to the moving direction of the first adsorption belt 12 .

[0096] Further, the width of the separator 17 is greater than the width of the support surface 21, thereby avoiding direct contact between the support 2 and the first adsorption belt 12 and the second adsorption belt 13, and preventing the support 2 from being damaged by high temperature caused by laser ablation.

[0097] In an optional implementation, the support member 2 protrudes from the upper surface of the partition member 17 located on the first end surface 111 .

[0098] like Figure 2 and Figure 3 As shown, the separator 17 on the first end surface 111 has an upper surface protruding from the upper surface of the first adsorption belt 12 and also protruding from the upper surface of the second adsorption belt 13 , so as to separate the first adsorption belt 12 from the second adsorption belt 13 .

[0099] Further explanation: the support member 2 protrudes from the upper surface of the separator 17 on the first end surface 111, so the support member 2 also protrudes from the first adsorption belt 12 and the second adsorption belt 13 located on the first end surface 111. While the support member 2 supports the tab, it can avoid laser cutting of the separator 17, the first adsorption belt 12 and the second adsorption belt 13. In addition, it is convenient to manually lift the support member 2 to the bottom surface of the upper adsorption chamber so that the support member 2 can be easily disassembled and replaced.

[0100] In an alternative embodiment, Figure 2 As shown, the width of the first adsorption belt 12 is greater than the width of the second adsorption belt 13 .

[0101] The width of the first adsorption belt 12 can be understood as the size of the first adsorption belt 12 in a direction perpendicular to the moving direction of the first adsorption belt 12 .

[0102] The width of the second adsorption belt 13 can be understood as the size of the second adsorption belt 13 in a direction perpendicular to the moving direction of the second adsorption belt 13 .

[0103] To further illustrate, the width of the first adsorption belt 12 is greater than the width of the second adsorption belt 13, wherein the main body of the pole piece 200 is located on the first adsorption belt 12, and after the waste on the pole piece 200 is cut off, the pole ear of the pole piece 200 is located on the second adsorption belt 13, and the width of the main body is greater than the width of the pole ear, so the width of the first adsorption belt 12 is greater than the width of the second adsorption belt 13, which is conducive to the transfer of the pole piece 200 and will not cause waste of resources.

[0104] According to a second aspect of an embodiment of the present application, a tab cutting device is provided, comprising the traction and adsorption mechanism 100 as described above.

[0105] In an optional embodiment, the tab cutting device further includes: an upper traction adsorption mechanism 300, wherein the upper traction adsorption mechanism 300 is spaced apart from the traction adsorption mechanism 100 and forms a cutting area;

[0106] The support member 2 extends toward the cutting area and forms a gap with the lower end surface of the upper traction adsorption mechanism 300;

[0107] A laser mechanism is used for cutting the pole lug.

[0108] Among them, the traction adsorption mechanism 100 is arranged at intervals from the upper traction adsorption mechanism 300, the cutting area is located between the upper adsorption cavity 300 and the traction adsorption mechanism 100 and close to the upper traction adsorption mechanism 300, the laser mechanism is arranged above the cutting area, and the irradiation direction of the laser line is perpendicular to the cutting area to cut the pole piece 200.

[0109] The pole piece is partially located at the upper traction and adsorption mechanism 300, and partially located at the traction and adsorption mechanism 100. When the pole ear is cut by the laser mechanism between the traction and adsorption mechanism 100 and the upper traction and adsorption mechanism 300, only one pole ear and the adjacent waste are located on the support 2 at the same time, and the pole ear at the other end of the waste is located in the gap, so the laser line will only cut the support 2 once when cutting the pole ear, thereby reducing the dust generated when the support 2 is ablated.

[0110] The tab cutting device further includes a negative pressure pipeline, which is used to communicate with the negative pressure chamber 113 in the traction and adsorption mechanism 100 so as to generate negative pressure in the negative pressure chamber 113 .

[0111] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
