[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] This embodiment provides an electrode collection device, such as... Figure 1 and Figure 2 As shown, the electrode receiving device includes a base 10, at least two mounting seats 20, a lifting mechanism 30, and a support member 40. The at least two mounting seats 20 are spaced apart in a first direction (X direction in the figure), and the distance between at least the two outermost mounting seats 20 in the first direction is adjustable. The lifting mechanism 30 and the support member 40 are respectively arranged in a one-to-one correspondence with the mounting seats 20. The lifting mechanism 30 is installed on the mounting seat 20, and the support member 40 is installed on the output end of the lifting mechanism 30. The lifting mechanism 30 can drive the support member 40 to reciprocate in a third direction (Z direction in the figure, that is, the vertical direction, and the Z direction is perpendicular to the X direction).

[0043] The aforementioned electrode receiving device adjusts the distance between the two outermost mounting seats 20. When the size of the electrode changes in the first direction, the distance between the two mounting seats 20 can be changed to support electrodes of different sizes. When the electrode warps, the lifting mechanism 30 corresponding to the side of the electrode that is warped higher drives the support member 40 to descend, thereby reducing the degree of warping at the warped position of the electrode, making the electrode more flat, and thus improving the stability of subsequent stacking.

[0044] Optionally, such as Figure 1 and Figure 2As shown, there are three mounting seats 20. The middle mounting seat 20 is fixedly connected to the base 10 as a fixed mounting seat 201. The other two mounting seats 20 are movable mounting seats 202. The two movable mounting seats 202 are slidably engaged with the base 10. The electrode receiving device also includes a lateral adjustment mechanism 50. The lateral adjustment mechanism 50 includes a cross-scissor assembly 51. The middle of the cross-scissor assembly 51 is pivotally connected to the fixed mounting seat 201, and the two ends of the cross-scissor assembly 51 are respectively pivotally connected to the two movable mounting seats 202. With the above configuration, on the one hand, the three support members 40 spaced apart along the first direction jointly support one electrode, which can support both ends and the middle of the electrode simultaneously. At the same time, when the middle of the electrode bends, the height of the middle support member 40 can be adjusted accordingly, making the adjustment of the electrode curling more flexible. On the other hand, the cross-scissor assembly 51 ensures that when the spacing between the two movable mounting seats 202 is adjusted, they are always symmetrically adjusted with the fixed mounting seat 201 as the center, ensuring that the middle position of the supported electrode remains unchanged. When the width of the electrode changes, it is not necessary to move the base 10 to align with the electrode.

[0045] Optionally, such as Figure 2 As shown, the cross-shear assembly 51 includes a first rod 511, a second rod 512, a third rod 513, a fourth rod 514, a fifth rod 515, and a sixth rod 516. The first rod 511 and the second rod 512 cross and are pivotally connected to the bottom of the fixed mounting base 201. The first end of the third rod 513 and the first end of the fourth rod 514 are pivotally connected to the bottom of one of the movable mounting bases 202. The second end of the third rod 513 is rotatably connected to the first end of the first rod 511. The second end of the fourth rod 514 is rotatably connected to the first end of the second rod 512. The first end of the fifth rod 515 and the first end of the sixth rod 516 are pivotally connected to the bottom of another movable mounting base 202. At the bottom of a movable mounting base 202, the second end of the fifth rod 515 is rotatably connected to the second end of the first rod 511, and the second end of the sixth rod 516 is rotatably connected to the second end of the second rod 512. That is, the first rod 511, the second rod 512, the third rod 513, and the fourth rod 514 form a rhombus. When one of the movable mounting bases 202 moves along the first direction, the shape of one rhombus changes, causing the other rhombus to change symmetrically, thereby ensuring that the adjustment amount of the two movable mounting bases 202 is consistent.

[0046] Of course, in another alternative embodiment, only two movable mounting bases 202 are provided, and the middle of the cross-scissor assembly 51 is pivotally connected to the base 10, which can also achieve support for electrodes of different sizes and improve the warping of electrodes.

[0047] When the width of the electrode changes, either movable mounting base 202 can be pulled or pushed.

[0048] Optionally, such as Figures 1-3 As shown, the top surface 12 of the base 10 has a first groove 121 extending in a first direction. The mounting base 20 includes a body 21 and a mounting part 22. The body 21 passes through the first groove 121, and the mounting part 22 is connected to the body 21 and confined to the top surface 12 of the base 10. The lifting mechanism 30 is disposed within the mounting part 22. With the above arrangement, part of the structure of the base 10 can be concealed inside the base 10, making the appearance of the electrode receiving device simpler.

[0049] Optionally, the cross-scissor assembly 51 is mounted on the body 21. By pulling or pushing the mounting part 22 from the outside, the body 21 slides along the first slide groove 121, thereby achieving the adjustment of the spacing.

[0050] During the electrode receiving process, the movable mounting base 202 may still experience slight movement in the first direction. To address this issue, such as... Figure 1 and Figure 2 As shown, the lateral adjustment mechanism 50 also includes a locking component 52, which includes a threaded cylinder 521 and a first knob 522. The threaded cylinder 521 extends along a second direction (Y direction in the figure, which is perpendicular to the X and Z directions respectively) and is fixedly connected to either of the two movable mounting seats 202. The first knob 522 includes a connected abutment portion 5221 and a threaded portion 5222. The front sidewall 11 of the base 10 has an elongated hole 111 along the first direction. The threaded portion 5222 is threadedly connected to the threaded cylinder 521 and passes through the elongated hole 111. The abutment portion 5221 can abut against the front sidewall 11 of the base 10. Specifically, the threaded cylinder 521 is connected to the main body 21 and is concealed inside the base 10. It can be understood that when the movable mounting seat 202 is adjusted to the correct position, the abutment part 5221 is tightened until it abuts against the front side wall 11. At this time, the abutment part 5221 and the main body 21 clamp the part of the base 10 between the first slide groove 121 and the front side wall 11, so as to achieve the function of fixing the position of the movable mounting seat 202. At the same time, when the threaded part 5222 is loosened, the movable mounting seat 202 can be moved. At this time, the threaded part 5222 moves in the elongated hole 111 without affecting the position adjustment of the movable mounting seat 202.

[0051] Optionally, such as Figure 4 and Figure 5As shown, the mounting part 22 has two side plates 221 arranged opposite to each other along the second direction. The lifting mechanism 30 includes a lead screw 31, a second knob 32, two lifting rods 33, and a guide member 36. The lead screw 31 is connected to the second knob 32. The lead screw 31 extends along the second direction and its two ends are pivotally connected to the two side plates 221 respectively. The lead screw 31 has two threaded sections 311 with opposite directions. The second knob 32 is located outside the mounting part 22. The two lifting rods 33 are arranged one-to-one with the threaded sections 311. One end of the lifting rod 33 is pivotally connected to the nut 34. The nut 34 is threadedly connected to the corresponding threaded section 311. The other end of the lifting rod 33 is pivotally connected to the support member 40. The guide member 36 extends along the second direction and its two ends are connected to the two side plates 221 respectively. The nut 34 is also in sliding fit with the guide member 36. With the above configuration, when the second knob 32 is turned, the two nuts 34 move closer or further apart. When the two nuts 34 move closer together, the two lifting rods 33 gradually approach verticality, causing the support member 40 to gradually rise. When the two nuts 34 move further apart, the two lifting rods 33 gradually approach horizontality, causing the support member 40 to gradually lower. The guide member 36 prevents the nuts 34 from rotating. In this embodiment, two guide members 36 are provided, located on opposite sides of the nuts 34, ensuring the force balance of the nuts 34.

[0052] Optionally, such as Figure 4 As shown, a connecting seat 35 is provided on the lower side of the support member 40 corresponding to the lifting rod 33. The other end of the lifting rod 33 is pivotally connected to the connecting seat 35. The connecting seat 35 provides an installation position for the pivot connection between the lifting rod 33 and the support member 40.

[0053] Optionally, such as Figure 2 and Figure 4 As shown, the mounting part 22 is groove-shaped, and the lifting rod 33 can be accommodated in the mounting part 22 when the support member 40 is at its lowest position. Through the above arrangement, the lead screw 31, nut 34 and lifting rod 33 inside the mounting part 22 can be protected to a certain extent, and at the same time, they can be dustproofed.

[0054] Optionally, such as Figure 2 As shown, the base 10 is a box-shaped structure with its opening facing downwards. One side wall of the base 10, facing each other in the second direction, is a sliding groove seat 13. The sliding groove seat 13 has a second sliding groove 131 along the first direction. The movable mounting base 202 is connected to the slider 24 via a connecting rod 23 extending in the second direction. The slider 24 is slidably connected to the second sliding groove 131. With the above arrangement, the movable mounting base 202 is simultaneously limited by the first sliding groove 121 and the second sliding groove 131 when sliding, further ensuring that the movable mounting base 202 does not tilt during the sliding process.

[0055] Optionally, such as Figure 1As shown, the electrode receiving device also includes a limiting component 60, which includes four columns 61. The four columns 61 are respectively disposed at the four corners of the top of the base 10, and the positions of the columns 61 are adjustable in the first direction. The arrangement of the columns 61 can prevent the electrode from shifting when vibration occurs. Specifically, the adjustable method is to open an elongated hole extending in the first direction on the top surface 12, and screws are threaded through the elongated hole and connected to the bottom of the column 61.

[0056] In this embodiment, the cross-section of the column 61 is linear; in other embodiments, such as... Figure 6 As shown, the cross-section of column 61 is L-shaped, which is not limited here.

[0057] This embodiment provides a battery production line, including the aforementioned electrode receiving device. By employing the electrode receiving device, the battery production line can accommodate electrode sheets of different widths, while also mitigating electrode warping issues and improving the quality of the finished battery.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
