Background

The cylindrical battery has the advantages of high energy density, high average output voltage, good cycle performance, long service life and the like, and is widely applied to various lamps, electric tools, toy models and other products.

When manufacturing the cylindrical battery, the cover plate is firstly fixed on the tab, and then the tab is bent, so that the cover plate is pre-covered after the tab is bent. After the tab is bent once, the plane of the cover plate of the battery is perpendicular to the end face of the columnar body of the battery, and the tab is required to be bent twice, so that the cover plate is aligned with the end face of the columnar body. However, since the tab has a certain length, after the tab is secondarily bent, the cover plate fixed to the end of the tab may deviate from the end surface of the cylindrical body. Therefore, the tab needs to be bent first, and then the cover plate is reversely folded, so that the cover plate is aligned to the end face of the columnar body. At present, the cover plate is bent manually by a worker to enable the end face of the cover plate and the end face of the columnar body to be aligned, however, the bending efficiency of the manual bending mode is low, and the market demand cannot be met.

The embodiment of the utility model provides a bending device and battery manufacturing equipment, which are used for solving the technical problem of low bending efficiency of a tab.

In the embodiment of the utility model, as shown in fig. 1, the bending device comprises a mounting seat 1, a limiting piece 3, a supporting seat 5, a pushing plate 6 and at least two clamping jaws 2, wherein the clamping jaws 2 are oppositely arranged on the mounting seat 1, and the clamping jaws 2 can be mutually close to or mutually far away from each other; the limiting piece 3 is arranged on the outer side of the clamping jaw 2, the limiting piece 3 and the tail end of the clamping jaw 2 in the vertical direction are arranged at intervals, and the limiting piece 3 and the clamping jaw 2 are positioned on the same straight line; a carrying platform 51 is arranged on the supporting seat 5, and the carrying platform 51 is positioned right below the clamping jaw 2; the pushing plate 6 is arranged on the supporting seat 5, the pushing plate 6 is positioned below the limiting piece 3, and the pushing plate 6 can move along the direction approaching or separating from the limiting piece 3; the thickness of the push plate 6 in a direction parallel to the direction in which the jaws 2 approach each other is smaller than the spacing of the spacing member 3 from the jaws 2 in a direction parallel to the direction in which the jaws 2 approach each other.

As shown in fig. 1, the vertical direction, the direction in which the pushing plate 6 approaches or departs from the stopper 3, and the axial direction of the guide rod 20 are all parallel to the Z axis, and the straight lines formed by the approach or departure of the clamping jaw 2 from each other and the connection of the stopper 3 and the clamping jaw 2 are all parallel to the X axis.

In an embodiment, as shown in fig. 4 and 5, the battery 40 includes a cylindrical body 401, a tab 402 and a cover plate 403, the tab 402 is disposed on an end surface of the cylindrical body 401, and the cover plate 403 is disposed on an end of the tab 402 away from the cylindrical body 401. I.e. the battery 40 of the present embodiment may be a cylindrical battery 40.

In an embodiment, the tab 402 includes a fixing portion and a connecting portion, the fixing portion is disposed on an end surface of the columnar body 401, and two ends of the connecting portion are respectively connected with the fixing portion and the cover plate 403.

As shown in fig. 4 and 5, when the tab 402 is not bent, the plane of the cover plate 403 is in the same plane as the end surface of the columnar body 401. When the end, close to the fixing portion, of the connecting portion is taken as a bending position, the tab 402 is bent by 90 degrees, and the plane where the cover plate 403 is located is perpendicular to the end face of the columnar body 401, namely, one-time bending of the battery 40 is achieved. Then, continuing to bend the tab 402, and continuing to bend the tab 402 by 90 degrees by taking one end of the connecting part, which is close to the fixing part, as a bending position; and the end of the connecting part, which is close to the cover plate 403, is used as another bending position to reversely bend the tab 402, so that the plane of the cover plate 403 is parallel to the end face of the columnar body 401, and secondary bending of the battery 40 is realized.

Since the jaws 2 are disposed opposite to each other, the columnar body 401 can be placed between the oppositely disposed jaws 2 so that the jaws 2 can grip the columnar body 401. When the clamping jaws 2 are close to each other, the clamping jaws 2 close to each other can press the end face of the columnar body 401, so that the columnar body 401 can be clamped and positioned, and shake of the columnar body 401 is reduced. The jaws 2 can release the cylindrical body 401 when the jaws 2 are moved away from each other.

The outer side of the clamping jaw 2, i.e. the side of the clamping jaw 2 facing away from the other clamping jaw 2 arranged opposite thereto, may be such that the limiting member 3 is in line with the clamping jaw 2, i.e. the side outside the oppositely arranged clamping jaw 2. Because the spacing piece 3 and the tail end of the clamping jaw 2 in the vertical direction are arranged at intervals, a bending space 4 can be formed between the spacing piece 3 and the tail end of the clamping jaw 2, so that the cover plate 403 can be reversely folded when the tab 402 is bent.

The support base 5 is provided with a carrier 51, and the carrier 51 is used for placing the columnar body 401. The carrier 51 is located directly below the clamping jaw 2, so that the clamping jaw 2 can clamp two end surfaces of the columnar body 401 placed on the carrier 51, and positioning of the columnar body 401 is achieved.

The pushing plate 6 is arranged on the supporting seat 5, and the pushing plate 6 is positioned below the limiting piece 3. When the pushing plate 6 moves along the direction approaching to the limiting piece 3, the pushing plate 6 can push the tab 402 located in the bending space 4 formed between the limiting piece 3 and the clamping jaw 2, so that the tab 402 is stressed and bent.

The thickness of the pushing plate 6 along the direction parallel to the direction in which the clamping jaws 2 are close to each other is smaller than the distance between the limiting piece 3 and the clamping jaws 2 along the direction parallel to the direction in which the clamping jaws 2 are close to each other, so that the pushing plate 6 can extend into the bending space 4, and the tab 402 is pushed to bend in the bending space 4 by the pushing plate 6.

In an embodiment, as shown in fig. 1 and 3, the clamping jaw 2 can move along a vertical direction, so that the clamping jaw 2 can be moved towards the carrying platform 51, so that the clamping jaw 2 clamps the columnar body 401 placed on the carrying platform 51. The support base 5 may be movable relative to the mounting base 1.

In an embodiment, the mounting base 1 and the supporting base 5 may be integrally provided or may be separately provided.

As shown in fig. 1 to 5, a process of secondarily bending the tab 402 according to an embodiment will be described in detail as follows:

the clamping jaw 2 is moved upward, then the battery 40 is placed on the carrier 51, and then the clamping jaw 2 is moved downward so as to bring the clamping jaws 2 close to each other to clamp and position the columnar body 401 of the battery 40. After the clamping jaw 2 clamps the columnar body 401, the columnar body 401 is located on the carrying platform 51, the tab 402 is located at the opening of the bending space 4, and one end of the cover plate 403, which is far away from the columnar body 401, is located under the limiting part 3. The push plate 6 is then moved upward so that the push plate 6 pushes the tab 402 so that the tab 402 moves upward. Because the end of the cover plate 403 far away from the columnar body 401 is directly under the limiting member 3, the limiting member 3 can prevent the end of the cover plate 403 far away from the columnar body 401 from moving upwards, and the end of the cover plate 403 close to the columnar body 401 moves upwards along with the tab 402 until the plane of the cover plate 403 is parallel to the end face of the columnar body 401, and the pushing plate 6 stops moving upwards. In the process, the tab 402 is bent by the thrust of the pushing plate 6, and the cover plate 403 is limited by the limiting piece 3 and driven by the tab 402 to realize reverse folding, so that the tab 402 is bent secondarily.
