[0035] In the embodiments of the present application, the mounting base 4 is mounted on the base 1, the adjusting assembly 3 is movably connected to the mounting base 4, and the pressing knife 2 is connected to the adjusting assembly 3; the base 1 is provided with a working surface 5, the pressing knife 2 is arranged opposite to the working surface 5, and a pressing space for stacking the pole pieces is formed between the pressing knife 2 and the working surface 5; the adjusting assembly 3 is arc-surface matched with the mounting base 4, and the adjusting assembly 3 is movable relative to the mounting base 4 to adjust the relative position of the pressing knife 2 and the working surface 5. In this way, the arc-surface matching between the adjusting assembly 3 and the mounting base 4 is used to facilitate the rapid adjustment of the parallelism of the pole pieces on the pressing knife 2 and the working surface 5. In addition, since the arc-surface matching is used between the adjusting assembly 3 and the mounting base 4, the position of the pressing knife 2 can be infinitely adjusted, and the parallelism of the pressing knife 2 relative to the pressing knife 2 seat can be more accurately adjusted.

[0036] It should be noted that, as shown in Figure 1 and Figure 2 , the adjusting assembly 3 can be moved along a first direction X first, and then moved along a second direction Y, or can be moved only along the first direction X or only along the second direction Y, so as to adjust the relative position of the pressing knife 2 connected to the adjusting assembly 3 and the pole pieces on the working surface 5, so that the pressing knife 2 and the pole pieces are parallel, and the uneven force on the contact surface of the pole pieces and the pressing knife 2 caused by the non-parallelism of the two is avoided, thereby affecting the performance of the battery cell.

[0037] Optionally, as shown in Figures 1 to 3 、 Figures 6 to 7 , the adjusting assembly 3 comprises a first adjusting piece 31; the first adjusting piece 31 is movably connected to the mounting base 4, and the first adjusting piece 31 is connected to the pressing knife 2; the first adjusting piece 31 is provided with a first arc convex surface 33 near one side of the mounting base 4, the mounting base 4 is provided with a first arc concave surface 34 near the side of the first adjusting piece 31, the first arc convex surface 33 and the first arc concave surface 34 are in contact, and the first adjusting piece 31 is movable relative to the first arc concave surface 34 to drive the pressing knife 2 to swing.

[0038] In the embodiment, the first adjusting piece 31 is movably connected to the mounting base 4, and the first adjusting piece 31 is connected to the pressing knife 2; the first adjusting piece 31 is provided with a first arc convex surface 33 near one side of the mounting base 4, the mounting base 4 is provided with a first arc concave surface 34 near the side of the first adjusting piece 31, the first arc convex surface 33 and the first arc concave surface 34 are in contact, and the first adjusting piece 31 is movable relative to the first arc concave surface 34 to drive the pressing knife 2 to swing. In this way, the first adjusting piece 31 and the mounting base 4 are matched by the arc to facilitate the swinging of the pressing knife 2 along the moving direction of the first adjusting piece 31, and the parallelism between the pressing knife 2 and the pole piece is adjusted.

[0039] Exemplarily, as shown in Figure 2 , the pressing knife 2 has four orientations of front, back, left and right, wherein the front-back orientation is the second direction Y, and the left-right orientation is the first direction X; assuming that the pressing knife 2 is inclined to the right, that is, a smaller included angle is formed between the pressing knife 2 and the pole piece, at this time, the first adjusting piece 31 can be adjusted to move to the left to drive the first adjusting piece 31 to swing to the left, and then the included angle between the pressing knife 2 and the pole piece is eliminated to make them parallel.

[0040] It should be noted that in the process of moving the first adjusting piece 31, the pressing knife 2 is simultaneously moved and rotated, and then the parallelism between the pressing knife 2 and the pole piece is adjusted.

[0041] In some embodiments, as shown in Figure 2 , the mounting base 4 is provided with a first scale line 8 in the moving direction of the first adjusting piece 31, and the first scale line 8 is used to mark the moving distance of the first adjusting piece 31 relative to the mounting base 4. In this way, the user can know the moving distance of the first adjusting piece 31 according to the first scale line 8, and then the parallelism between the pressing knife 2 and the pole piece is more accurately adjusted.

[0042] Optionally, as shown in Figures 2 to 4As shown, the adjusting assembly 3 further comprises a first pin 37 and a first fastener; the first adjusting member 31 is provided with a first mounting groove 12, the first pin 37 is movably connected to the first mounting groove 12, the first adjusting member 31 is provided with a first mounting hole 39, the first fastener is arranged in the first mounting hole 39, one end of the first fastener is connected with the first pin 37, and the other end is connected with the mounting base 4, and a gap is formed between the first fastener and the first mounting hole 39.

[0043] In the embodiment, the first mounting groove 12 is arranged in the first adjusting member 31, the first pin 37 is movably connected to the first mounting groove 12, the first adjusting member 31 is provided with the first mounting hole 39, the first fastener is arranged in the first mounting hole 39, one end of the first fastener is connected with the first pin 37, and the other end is connected with the mounting base 4, and a gap is formed between the first fastener and the first mounting hole 39. In this way, the first adjusting member 31 can be mounted on the mounting base 4 through the first fastener; in addition, when the first adjusting member 31 moves, the first pin 37 is driven to rotate, so that the connecting surface of the first fastener and the first pin 37 rotates, thereby maintaining the connection between the first adjusting member 31 and the mounting base 4; further, since the gap is formed between the first fastener and the first mounting hole 39, the first adjusting member 31 can move in the gap, thereby realizing the movement of the first adjusting member 31.

[0044] In some embodiments, as Figure 4 shown, the size of the first mounting hole 39 in the first direction X is greater than the diameter of the first fastener, so that a gap is formed between the first fastener and the first mounting hole 39 in the first direction X, and the first adjusting member 31 can move in the gap.

[0045] For example, the first mounting hole 39 can be a waist-shaped hole or a strip-shaped hole; the length direction of the waist-shaped hole or the strip-shaped hole (the first direction X) is the same as the moving direction of the first adjusting member 31. In this way, when the first adjusting member 31 moves, the first fastener can be limited to move along the length direction of the waist-shaped hole or the strip-shaped hole, and cannot move or can move slightly in the width direction of the waist-shaped hole or the strip-shaped hole (the second direction Y).

[0046] Alternatively, as Figure 2 and Figure 3 shown, the adjusting assembly 3 further comprises a first adjusting screw; the mounting base 4 is provided with a first fixing table 6 on both sides in the moving direction of the first adjusting member 31, and the first adjusting screw is movably connected to the first fixing table 6; the first adjusting screw abuts against the first adjusting member 31, and the first adjusting screw can move relative to the first fixing table 6 to adjust the relative position of the first adjusting member 31 and the mounting base 4.

The first adjusting bolt abuts against the first adjusting member 31, and the first adjusting bolt is movable relative to the first fixing table 6 to adjust the relative position of the first adjusting member 31 and the mounting base 4. In this way, the relative position of the first adjusting member 31 and the mounting base 4 can be adjusted by the first adjusting bolt, which is convenient and fast. In addition, after the relative position of the first adjusting member 31 and the mounting base 4 is adjusted, the first adjusting member 31 can be fixed by the first adjusting bolt on both sides to maintain the relative position of the first adjusting member 31 and the mounting base 4.

[0048] In some embodiments, as shown in Figure 2 and Figure 3 , the first fixing table 6 can be directly welded with the mounting base 4, or can be threadedly connected with the mounting base 4 through bolts. Further, the first fixing table 6 is provided with a first threaded hole, and the first adjusting bolt is movable relative to the first threaded hole, so that the first adjusting bolt abuts against the first adjusting member 31, thereby adjusting the relative position of the first adjusting member 31 and the mounting base 4.

[0049] Optionally, as shown in Figure 2 and Figure 3 , and Figure 8 , the adjusting assembly 3 further comprises a second adjusting member 32. The second adjusting member 32 is arranged on the side of the first adjusting member 31 away from the mounting base 4 and is movably connected to the first adjusting member 31. The second adjusting member 32 is connected to the presser 2. The side of the second adjusting member 32 close to the first adjusting member 31 is provided with a second arc convex surface 35, and the side of the first adjusting member 31 close to the second adjusting member 32 is provided with a second arc concave surface 36. The second arc convex surface 35 and the second arc concave surface 36 are in contact, and the second adjusting member 32 is movable relative to the second arc concave surface 36 to drive the presser 2 to swing. The moving direction of the second adjusting member 32 intersects with the moving direction of the first adjusting member 31.

[0050] In the embodiment of the present application, the second adjusting member 32 is arranged on the side of the first adjusting member 31 away from the mounting base 4 and movably connected to the first adjusting member 31, and the second adjusting member 32 is connected to the pressing knife 2. The side of the second adjusting member 32 close to the first adjusting member 31 is provided with a second circular-arc convex surface 35, the side of the first adjusting member 31 close to the second adjusting member 32 is provided with a second circular-arc concave surface 36, the second circular-arc convex surface 35 and the second circular-arc concave surface 36 are in contact, the second adjusting member 32 is movable relative to the second circular-arc concave surface 36 to drive the pressing knife 2 to swing, and the moving direction of the second adjusting member 32 intersects with the moving direction of the first adjusting member 31. In this way, the second adjusting member 32 and the first adjusting member 31 are circularly matched to facilitate driving the pressing knife 2 to swing along the moving direction of the second adjusting member 32, and thus the parallelism between the pressing knife 2 and the pole piece is adjusted. In addition, the moving direction of the second adjusting member 32 intersects with the moving direction of the first adjusting member 31 to facilitate adjusting the parallelism between the pressing knife 2 and the pole piece in two directions.

[0051] As shown in the examples of FIGS. 6 and 7, Figure 2 assuming that the pressing knife 2 is inclined forward, i.e., a small angle is formed between the pressing knife 2 and the pole piece, the second adjusting member 32 can be adjusted to move backward to drive the second adjusting member 32 to swing backward, and thus the angle between the pressing knife 2 and the pole piece is eliminated to make them parallel.

[0052] It should be noted that the moving direction of the first adjusting member 31 can be the first direction X, and the moving direction of the second adjusting member 32 can be the second direction Y, or the moving direction of the first adjusting member 31 can be the second direction Y, and the moving direction of the second adjusting member 32 can be the first direction X, as long as the moving direction of the second adjusting member 32 intersects with the moving direction of the first adjusting member 31.

[0053] In some embodiments, the first adjusting member 31 is provided with a second scale line 9 along the moving direction of the second adjusting member 32, and the second scale line 9 is used to indicate the moving distance of the second adjusting member 32 relative to the first adjusting member 31. In this way, the user can know the moving distance of the second adjusting member 32 according to the second scale line 9, and thus the parallelism between the pressing knife 2 and the pole piece can be more accurately adjusted.

[0054] Optionally, as shown in FIGS. 8 and 9, Figure 2 and Figure 4 the adjusting assembly 3 further comprises a second pin column 38 and a second fastener.

In this way, the second adjusting member 32 is installed on the first adjusting member 31 through the second fastener, the first adjusting member 31 can drive the second adjusting member 32 to move when the first adjusting member 31 moves, and then the second adjusting member 32 drives the pressure knife 2 to swing. In addition, when the second adjusting member 32 moves, the second pin column 38 is driven to rotate, so that the connecting surface of the second fastener and the second pin column 38 rotates, thereby maintaining the connection between the second adjusting member 32 and the first adjusting member 31. Further, since the gap is formed between the second fastener and the second mounting hole 40, the second adjusting member 32 can move in the gap, thereby realizing the movement of the second adjusting member 32.

[0056] In some embodiments, as shown in Figure 4 , the size of the second mounting hole 40 in the second direction Y is greater than the diameter of the second fastener, so that a gap along the second direction Y is formed between the second fastener and the second mounting hole 40, and the second adjusting member 32 can move in the gap.

[0057] Exemplarily, the second mounting hole 40 can be a waist-shaped hole or a strip-shaped hole, and the length direction (the second direction Y) of the waist-shaped hole or the strip-shaped hole is the same as the moving direction of the second adjusting member 32. In this way, when the second adjusting member 32 moves, the second fastener can be limited to move along the length direction of the waist-shaped hole or the strip-shaped hole, and cannot move or can move slightly in the width direction (the first direction X) of the waist-shaped hole or the strip-shaped hole.

[0058] Optionally, as shown in Figures 1 to 4 , the first mounting groove 12 is arranged on both sides of the first adjusting member 31 along the moving direction of the second adjusting member 32.

[0059] In the embodiment of the present application, the first mounting groove 12 is arranged on both sides of the first adjusting member 31 along the moving direction of the second adjusting member 32. In this way, the second adjusting member 32 is facilitated to avoid the plane matched with the first adjusting member 31, so as to facilitate the cooperation between the two.

[0060] In some embodiments, as shown in Figure 2 and Figure 3As shown, two first mounting grooves 12 can be arranged on both sides of the moving direction of the first adjusting member 31 relative to the second adjusting member 32, so that the connection strength between the first adjusting member 31 and the mounting base 4 can be enhanced. In addition, the extending direction of the first mounting groove 12 intersects with the moving direction of the first adjusting member 31, so that when the first adjusting member 31 moves, the first pin column 37 can rotate along the groove wall of the first mounting groove 12.

[0061] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the second mounting groove 13 can be provided in two, and the two second mounting grooves 13 are arranged in a spaced manner along the direction of the second adjusting member 32, so that the connection strength between the second adjusting member 32 and the first adjusting member 31 can be enhanced. In addition, the extending direction of the second mounting groove 13 intersects with the moving direction of the second adjusting member 32, so that when the second adjusting member 32 moves, the second pin column 38 can rotate along the groove wall of the second mounting groove 13.

[0062] It should be noted that the groove wall of the first mounting groove 12 and the second mounting groove 13 can be partially provided in an arc shape, so that the first pin column 37 and the second pin column 38 can rotate in the corresponding mounting groove; in addition, the contact end face between the first pin column 37 and the first fastener, and the contact end face between the second pin column 38 and the second fastener can be provided as a flat surface. In this way, it is beneficial to enhance the contact area between the first fastener and the first pin column 37 and the contact area between the second fastener and the second pin column 38, so as to enhance the connection strength between the first fastener and the first pin column 37 and the connection strength between the second fastener and the second pin column 38.

[0064] In the embodiment of the present application, the second fixed table 7 is arranged on both sides of the first adjusting part 31 along the moving direction of the second adjusting part 32, and the second adjusting bolt is movably connected to the second fixed table 7. The second adjusting bolt abuts against the second adjusting part 32, and the second adjusting bolt can move relative to the second fixed table 7 to adjust the relative position of the second adjusting part 32 and the first adjusting part 31.
