For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 - Figure 4 As shown, a pole tab smoothing device provided by the utility model comprises a mounting frame 10 and a smoothing mechanism 100, the smoothing mechanism 100 is slidably connected to the mounting frame 10, and the smoothing mechanism 100 is used for smoothing the edge of the pole piece;

[0029] The smoothing mechanism 100 includes a moving assembly 110 , a first smoothing plate 120 and a second smoothing plate 130 . The first smoothing plate 120 and the second smoothing plate 130 are mounted on the moving assembly 110 . The moving assembly 110 is used to adjust the angle of the first smoothing plate 120 .

[0030] The second caressing plate 130 is disposed at an angle to the first caressing plate 120 , and the angle between the second caressing plate 130 and the first caressing plate 120 is adjustable.

[0031] By setting the moving component 110, the positions of the first and second caressing plates 120 and 130 relative to the pole ears can be effectively adjusted, wherein the first and second caressing plates 120 and 130 are installed on the moving component 110, and the first and second caressing plates 120 and 130 are respectively abutted against the outer sides of the pole ears, and the pole ears at the edges of the cathode ear and the anode ear are respectively pushed by the first and second caressing plates 120, thereby effectively improving the smoothing quality of the pole ears. At the same time, in order to facilitate further smoothing of the pole ears at the edges of the cathode and anode sheets, the second caressing plate 130 is arranged at an angle to the first caressing plate 120, and the angle between the second caressing plate 130 and the first caressing plate 120 is adjustable, thereby alleviating the technical problem existing in the prior art that the position where one side of the pole sheet is tangent to the winding needle is located opposite to the pole ear caressing plate, resulting in the caressing plate not being able to just smooth to the position where the pole sheet is tangent to the winding needle, resulting in an unsatisfactory smoothing effect, thereby achieving the technical effect of improving product production quality.

[0032] Further, the moving assembly 110 includes a cylinder 111, a push block 112 and a connecting rod 113, the first caressing plate 120 is rotatably connected to the mounting frame 10, the driving end of the cylinder 111 is connected to the push block 112, one end of the connecting rod 113 is rotatably connected to the push block 112, and the other end is rotatably connected to the first caressing plate 120;

[0033] The cylinder 111 is used to drive the push block to move.

[0034] One end of the push block 112 is connected to the cylinder 111, and reciprocates under the action of the cylinder 111. The other end of the push block 112 is rotatably connected to the connecting rod 113. Since the first caressing plate 120 is rotatably connected to the mounting frame 10 and the other end of the connecting rod 113 is rotatably connected to the first caressing plate 120, under the action of the reciprocating motion of the push block 112, the connecting rod 113 drives the first caressing plate 120 to swing, so that the angle of the first caressing plate 120 can be adjusted. When the cylinder 111 is in the extended position, the first caressing plate 120 swings to fit the pole ear at the edge of the pole piece. When the cylinder 111 is in the retracted position, the first caressing plate 120 swings away from the pole ear. By controlling the position of the extended position of the cylinder 111, the swing angle of the first caressing plate 120 can be adjusted.

[0035] Furthermore, the smoothing mechanism 100 also includes a connecting plate 140, the first smoothing plate 120 includes a first support plate 150 arranged toward the second smoothing plate 130, and the first support plate 150 is arranged on the edge of the first smoothing plate 120 to avoid scratching the pole ear; the connecting plate 140 is threadedly connected between the first support plate 150 and the second smoothing plate 130.

[0036] Furthermore, a first adjustment hole group 160 is provided at the connection between the connecting plate 140 and the first support plate 150. The first adjustment hole group 160 penetrates the connecting plate 140 and extends in a direction perpendicular to the first caressing plate 120. The connecting plate 140 is connected to the first support plate 150 at different positions of the first adjustment hole group 160 to adjust the distance of the connecting plate 140 relative to the first caressing plate 120, thereby adjusting the distance between the second caressing plate 130 and the first caressing plate 120.

[0037] A second support plate 180 is provided at the connection between the second smoothing plate 130 and the connecting plate 140, and an angle adjustment hole 170 is provided at the connection between the second support plate 180 and the connecting plate 140.

[0038] The second caressing plate 130 is threadedly connected to the connecting plate 140 through the angle adjustment hole 170 ; and the second caressing plate 130 adjusts the connection angle between the second caressing plate 130 and the first caressing plate 120 by controlling the connection angle between the angle adjustment hole 170 and the connecting plate 140 .

[0039] Furthermore, the inner surface of the angle adjustment hole 170 is a curved surface.

[0040] The inner surface of the angle adjustment hole 170 is designed to be a curved surface, thereby increasing the angle adjustment range of the second smoothing plate 130 relative to the connecting plate 140 .

[0041] Furthermore, the end of the second caressing plate 130 away from the first caressing plate 120 is a curved surface.

[0042] The end of the second caressing plate 130 facing away from the first caressing plate 120 is a curved surface, which is convenient for guiding the pole ear at the edge of the pole piece and transitioning the pole ear into the area of ​​the first caressing plate 120. At the same time, it is prevented that the straight section of the first caressing plate 120 directly contacts the pole ear and causes the pole ear to bend.

[0043] Furthermore, a plurality of rollers 11 are rotatably connected to the mounting frame 10 for the diaphragm to pass through.

[0044] Furthermore, the first caressing plate 120 is rotatably mounted on the mounting frame 10 via a fixing block 121, one end of the connecting rod 113 is rotatably connected to the pushing block 112, and the other end is rotatably connected to the fixing block 121. Such an arrangement enables the first caressing plate 120 to swing under the action of the fixing block 121 and the connecting rod 113.

[0045] Furthermore, the fixing block 121 and the first caressing plate 120 are integrally formed.

[0046] The fixing block 121 and the first caressing plate 120 are integrally formed and manufactured, which is convenient for processing, production and on-site installation.

[0047] Furthermore, if Figure 5 As shown, the tab smoothing device is arranged on one side of the winding needle 1, the mounting frame 10 is mounted on a first mounting plate 30, the first mounting plate 30 is connected to a first driving member 20, and the first driving member 20 drives the first smoothing plate 120 to approach or move away from the winding needle 1 along a first direction.

[0048] The diaphragm 5 is transferred to the winding needle 1 through multiple rollers 11 provided in the tab smoothing device, and the winding needle 1 winds the diaphragm 5, the first pole piece 3, another diaphragm 5, and the second pole piece 4 in layers to form the battery cell 2. In the process of transferring the pole piece to the winding needle 1, the first smoothing plate 120 and the second smoothing plate 130 smooth the tabs at the edge of the pole piece to prevent the tabs from folding. As the diameter of the battery cell 2 continues to increase, the first driving member 20 drives the first smoothing plate 120 and the second smoothing plate 130 to gradually move away from the winding needle 1 in the first direction, so that the tab smoothing effect is better.

[0049] Furthermore, the first driving member 20 and the mounting frame 10 are integrally mounted on a second mounting plate 50, the second mounting plate 50 is connected to a second driving member 40, and the second driving member 40 drives the first smoothing plate 120 to approach or move away from the winding needle 1 along a second direction, and the second direction is perpendicular to the first direction.

[0050] When the winding needle 1 winds a small-sized battery cell 2, the second driving member 40 drives the first and second caressing plates 120 and 130 as a whole to approach the winding needle 1 along the second direction; when the winding needle 1 winds a large-sized battery cell 2, the second driving member 40 drives the first and second caressing plates 120 and 130 as a whole to move away from the winding needle 1 along the second direction. The mechanism can be adjusted as a whole to approach or move away from the winding needle 1 according to different diameter batteries 2.

[0051] The first driving member 20 and the second driving member 40 are preferably a motor and a screw assembly.
