For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0038] In the related art, because the tab material of the soft package battery cell is soft, it is easy to deform, such as wrinkling and skewing, thereby affecting the electrical connection performance of the battery cell. In view of the above problem, the embodiment of the present application provides a tab shaping device which can improve the flatness of the tab, ensure the consistency of the length and direction of the tab, and thereby improve the electrical connection performance of the battery cell.

[0039] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0040] Figure 1 is a structural schematic diagram of the tab shaping device shown in the embodiments of the present application.

[0041] Referring to Figure 1 , the present application provides a tab shaping device, which comprises a frame body 100, a shaping mechanism 200 and a controller (not shown); the frame body 100 is equipped with a first driving mechanism 110 and a second driving mechanism 120; the shaping mechanism 200 is installed on the frame body 100, and the shaping mechanism 200 comprises at least one set of upper shaping pieces 210 and lower shaping pieces 220; the power output end of the first driving mechanism 110 is connected with the lower shaping transmission, and the power output end of the second driving mechanism 120 is connected with the upper shaping piece 210 transmission; the upper shaping piece 210 comprises a first shaping plate for applying downward pressure to the tab, and the lower shaping piece 220 comprises a second shaping plate for applying upward pressure to the tab; the first shaping plate and the second shaping plate are oppositely arranged in the vertical direction; the controller is electrically connected with the first driving mechanism 110 and the second driving mechanism 120, and is used for controlling the operation of the first driving mechanism 110 and the second driving mechanism 120 to drive the upper shaping piece 210 and the lower shaping piece 220 to move towards or in the opposite direction.

[0042] In the related art, the unevenness of the tab of the battery cell can cause short circuit risk or local overheating phenomenon. The unevenness of the tab can have burrs or sharp parts, which can pierce the diaphragm inside the battery, causing the positive and negative electrodes to directly contact, triggering a short circuit, which can cause the battery to overheat, catch fire or even explode. Due to the increase of contact resistance and uneven distribution of current, local overheating phenomenon can occur at the uneven part of the tab. High temperature can accelerate the chemical reaction inside the battery, causing decomposition of electrolyte and gas generation, increasing the internal pressure of the battery, and further causing safety problems.

[0043] The tab shaping mechanism 200 provided by the present application has a space for accommodating the tab between the first shaping plate and the second shaping plate, the first shaping plate and the second shaping plate are respectively located on both sides of the tab thickness direction, when the first shaping plate and the second shaping plate move towards each other, pressure can be applied to the tab on both sides of the tab thickness direction, when the tab is in a bent state or uneven, the tab shape is changed to flat by the applied pressure, the tab flatness is improved, the consistency of the tab length and direction is ensured, and the electrical connection performance of the battery cell and the safety of the battery cell are improved.

[0044] The first driving mechanism 110 and the second driving mechanism 120 can include a gas cylinder or a motor, which is fixedly installed on the frame 100. When the first shaping plate and the second shaping plate move towards each other in the vertical direction Z and approach, the shaping of the tab can be realized, and when the first shaping plate and the second shaping plate move in the opposite direction in the vertical direction, they are restored to the original position.

[0045] The first shaping plate and the second shaping plate can be parallel plate-shaped components, and the plane where the plate-shaped components are located is perpendicular to the longitudinal direction. When the two approach each other, they can cover both the front and back surfaces of the tab, and then simultaneously extrude the two surfaces, so that the tab deforms under the extrusion force and tends to be flat. Uneven tabs can cause difficulties in the welding process, leading to poor welding, such as loose welding, delamination, etc., affecting the production yield and quality stability of the battery. On the automatic production line, uneven tabs can also affect the operation accuracy of the welding robot, increasing the probability of failure in the production process. The scheme of the present application can avoid the above problems in the related art because it can improve the flatness of the tab.
