When the positive electrode riveting block 102 is subjected to riveting operation, the upper surface of the positive electrode riveting block 102 deforms, so that the flatness of the upper surface of the positive electrode is reduced; similarly, when the negative riveting block 103 is riveted, the upper surface of the negative electrode of the negative riveting block 103 is also deformed, resulting in a reduction in the flatness of the upper surface of the negative electrode. In addition, when the top cover explosion-proof valve 104 is welded to the back surface of the valve spool of the top cover main body 101, the notch of the valve spool is also deformed, resulting in a reduction in the flatness of the notch of the valve spool.

At present, no method is available for improving the riveting or welding process to reduce the deformation degree of the battery top cover plate, but the requirement on the flatness of the battery top cover plate in the industry is high, so that the yield of the battery top cover plate is low.

Therefore, a deformation correction module is needed to improve the flatness of the deformation workpieces such as the battery top cover.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the referred devices or elements must have the specific orientations, be configured to operate in the specific orientations, and thus are not to be construed as limitations of the present invention.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 2 to 6, the present embodiment provides a deformation correction module, which is suitable for a deformed workpiece 2 with a deformed surface 201, and includes a lower die assembly 3, a guide pillar 5, and an upper die assembly 4. The lower die assembly 3 is provided with a fixing groove for fixing one end of the deformation workpiece 2 far away from the deformation surface 201. The upper die assembly 4 is located above the lower die assembly 3, a flattening block 401 is arranged at a position corresponding to the deformation surface 201, and the flattening block 401 is used for pressing the deformation surface 201 downwards to improve the flatness of the deformation surface 201. The upper die assembly 4 is connected with the upper end of the guide pillar 5 in a sliding manner, and the lower die assembly 3 is connected with the lower end of the guide pillar 5 in a sliding manner. Specifically, the guide post 5 can guide the sliding path of the upper die assembly 4, and ensure that the leveling block 401 is aligned with the deformation surface 201.

It can be understood that, the deformation surface 201 of the deformation workpiece 2 is placed upwards into the fixing groove of the lower die assembly 3, and then the upper die assembly 4 is driven to press the lower die assembly 3, and the flattening block 401 can be matched with the lower die assembly 3 to compress and flatten the deformation surface 201 from the upper side and the lower side, so that the bending deformation degree of the deformation surface 201 is reduced, and the flatness of the deformation surface 201 is improved. Therefore, the deformation correction module provided by the invention can correct the deformation of the deformed workpiece 2, so that the flatness of the deformed workpiece 2 is improved.

The upper die assembly 4 comprises a containing through groove 4031, the leveling block 401 is located in the containing through groove 4031, and when the upper die assembly 4 is pressed with the lower die assembly 3, the deformation surface 201 is located in the containing through groove 4031 to be attached to the bottom of the leveling block 401.

Specifically, the bottom of leveling block 401 does not protrude from the end surface of upper die assembly 4 adjacent to lower die assembly 3. It should be noted that, such an arrangement is beneficial to adapt to changes such as requirements on the height and the flatness of the deformation surface 201 only by replacing the leveling blocks 401 with different heights, and other components are not required to be replaced, so that the resource utilization rate is improved. For example, if the height of the positive riveting block is high or the requirement on the flatness is low, the leveling block 401 with a small height can be selected, and other parts of the lower die assembly 3 and the upper die assembly 4 do not need to be replaced; if the height of the positive riveting piece is relatively low or the requirement on the flatness is relatively high, the leveling block 401 with a relatively large height can be selected, and other parts of the lower die assembly 3 and the upper die assembly 4 do not need to be replaced.

Preferably, the upper die assembly 4 includes a first clamping plate 402 and a second clamping plate 403 positioned below the first clamping plate 402, and the receiving through slot 4031 is positioned in the second clamping plate 403. The groove wall of the accommodating through groove 4031 is provided with a first limiting boss 4032, and the side surface of the leveling block 401 is provided with a second limiting boss 4013 which is located above the first limiting boss 4032 and is matched with the first limiting boss 4032 to prevent the leveling block 401 from sliding downwards to be separated from the accommodating through groove 4031.

Specifically, the second limiting boss 4013 is located right above the first limiting boss 4032, and when the leveling block 401 slides down along the accommodating through groove 4031, the second limiting boss 4013 abuts against the first limiting boss 4032, so that the leveling block 401 is limited to continue to slide down, and the leveling block 401 is prevented from being separated from the accommodating through groove 4031.

Further, there is an adjustment gap between the top of the leveling block 401 and the bottom of the first clamping plate 402.

It should be noted that the adjustment gap may reserve space for the leveling blocks 401 of different heights. For example, if the height of the positive electrode riveting block is high or the requirement for flatness is low, and the leveling block 401 with a small height dimension is selected, then: before the deformation surface 201 enters the accommodating through groove 4031, the leveling block 401 slides downwards under the action of gravity until the second limiting boss 4013 is blocked by the first limiting boss 4032, and the leveling block 401 is short, so that the adjustment gap is large; after the deformed surface 201 enters the accommodating through groove 4031, the deformed surface 201 pushes the leveling block 401 upward so that the top of the leveling block 401 is attached to the bottom of the first clamping plate 402, and the leveling operation is realized. If the height of the positive riveting piece is shorter or the requirement on the flatness is higher, the leveling block 401 with the larger height dimension can be selected, and then: before the deformation surface 201 enters the accommodating through groove 4031, the leveling block 401 slides downwards under the action of gravity until the second limiting boss 4013 is blocked by the first limiting boss 4032, and the leveling block 401 is higher in height, so that the adjustment gap is smaller; after the deformed surface 201 enters the accommodating through groove 4031, the deformed surface 201 pushes the leveling block 401 upward so that the top of the leveling block 401 is attached to the bottom of the first clamping plate 402, and the leveling operation is realized.

In this embodiment, the leveling block 401 includes a leveling portion 4011 provided with the first limit projection 4032, and an adjusting portion 4012 located above the leveling portion 4011 and detachable from the leveling portion 4011.

Specifically, the leveling portion 4011 is placed in the accommodating through groove 4031, and when the height of the leveling portion 4011 needs to be adjusted, only the adjusting portion 4012 with different thicknesses needs to be replaced, that is to say: if a leveling block 401 with a higher height is needed, an adjusting part 4012 with a thicker thickness is selected, and the adjusting gap is smaller when the pressing is not carried out; if a leveling block 401 with a shorter height is required, an adjusting portion 4012 with a smaller thickness is selected, and the adjustment gap is larger when pressing is not performed.

Optionally, the second clamping plate 403 is provided with a sliding groove, a sliding plate 404 is arranged in the sliding groove, one end of the sliding plate 404 is provided with a containing groove 4041 for containing the adjusting portion 4012, and the other end of the sliding plate extends to the outside of the sliding groove.

It can be understood that, after the first clamping plate 402 and the second clamping plate 403 are fixedly connected, if the thickness of the adjusting portion 4012 needs to be adjusted, the first clamping plate 402 and the second clamping plate 403 do not need to be disassembled, the sliding plate 404 only needs to be drawn out along the sliding groove, and the sliding plate 404 is inserted into the sliding groove again after the new adjusting portion 4012 is placed in the containing groove 4041, which is simple and convenient.

Further, a through groove for the flat part 4011 to pass through is formed at the bottom of the holding groove 4041.

Specifically, when the upper and

lower die assemblies

4 and 3 are pressed, the deforming surface 201 pushes up the flattening portion 4011 so that the flattening portion 4011 passes through the through groove to be fitted with the adjustment portion 4012.

Preferably, a fixed baffle 4042 is fixedly arranged at the bottom of the sliding plate 404, and the fixed baffle 4042 is connected with the second clamping plate 403 through a fixed bolt 405.

Specifically, the fixing bolt 405 may prevent the sliding plate 404 from being loosened, and ensure that the adjustment portion 4012 and the flattening portion 4011 may be aligned.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
