[0062] The working principle of this utility model:

[0063] In this embodiment, the feeding conveyor belt 1, the first transfer conveyor belt 2, the second transfer conveyor belt 3, the NG conveyor belt 5, and the unloading conveyor belt 4 can all be selected as equidistant belt lines. The battery cover is fed by the feeding conveyor belt 1. In this embodiment, two flattening components are provided, and each flattening component is provided with a first conveying mechanism 18 on both the left and right sides, with the Y-axis direction being the auxiliary... Figure 1 The front and back directions, the X-axis direction is attached. Figure 1 The first Y-axis moving unit 25 can be selected to be a linear module set along the Y-axis direction and mounted on the bracket 17. The moving end of the first Y-axis moving unit 25 can drive the first lifting unit 24 along the Y-axis direction (i.e., the left and right directions); Figure 1 The first lifting unit 24 can be selected as a telescopic mechanism such as a cylinder or an electric cylinder, and the lifting end of the first lifting unit 24 can drive the first suction cup 23 to move up and down. Similarly, the structure and working principle of the second transport mechanism 19 and the third transport mechanism 20 are the same as those of the first transport mechanism 18.

[0064] The horizontal transplanting mechanism 7 can be a linear module that moves along the X-axis or a lead screw motor that causes the mounting plate 8 to move along the X-axis; the mounting plate 8 can be driven by a horizontal moving mechanism along the X-axis (see attached diagram). Figure 1 The fixture 9 can be inserted into the mounting plate 8 via the first guide post 27 for positioning. The fixture 9 can also be installed on the mounting plate 8 via bolts or other detachable structures. In this embodiment, two fixtures 9 are arranged side by side or adjacent to each other on the mounting plate 8, but not limited to two. After the flattening process of the previous fixture 9 is completed, the horizontal transfer mechanism 7 can drive the two fixtures 9 to move along the X-axis direction via the mounting plate 8, moving the other fixture 9 to the processing position directly below the flattening mechanism, so that the next flattening process can be performed on the adjacent fixture 9, which greatly improves the flattening and loading / unloading efficiency. The lifting mechanism 6 is used to drive the flattening mechanism to lift up and down. Similarly, the lifting mechanism 6 can be selected from lifting structures such as cylinders or electric cylinders.

[0065] The mold base plate 11 in the flattening mechanism is connected to the top of the limiting plate 12 via multiple first springs 14. The upper pressure plate 10 is fixedly connected to the mold base plate 11 via bolts or other connecting parts. The limiting plate 12 is connected to the top of the pre-pressing plate 13 via bolts or other connecting parts. The mold base plate 11 is connected to the limiting plate 12 via multiple first springs 14, and the mold base plate 11 is also connected to the limiting plate 12 via multiple equal-height connecting parts 21. The equal-height connecting parts 21 can be selected as equal-height screws, which can adjust the distance between the mold base plate 11 and the limiting plate 12. The multiple equal-height screws are located inside the limiting part 15. In this embodiment, the multiple equal-height screws are located inside the multiple first springs 14, and the multiple first springs 14 are all located inside the limiting part 15. Multiple second guide posts 28 extend vertically at the bottom of the mold base plate 11. The second guide posts 28 can pass through the second guide hole 29 and the first guide hole 26 in sequence to achieve a high-precision flattening process for the battery cover. The limiting part 15 extends downwards, and the distance between the bottom surface of the limiting part 15 and the mold base plate 11 is less than the distance between the top surface of the limiting plate 12 and the mold base plate 11. Furthermore, the vertical length of the limiting part 15 is less than the vertical length of the equal-height connector 21, thus limiting the shortest distance between the limiting plate 12 and the mold base plate 11, protecting the limiting plate 12 and the mold base plate 11, and preventing collision damage. The positioning groove 34 on the fixture 9 is used to fix and position the battery cover. In this embodiment, each fixture 9 corresponds to one battery cover. Multiple second springs 22 effectively buffer the impact of the flattening mechanism on the fixture 9 and the battery cover. In addition, in this embodiment, the length of the equal-height screw is shorter than the length of the uncompressed first spring 14.

[0066] The processed fixture 9 is driven by the horizontal transfer mechanism 7 to the first conveying mechanism 18 on the other side, such as the first conveying mechanism 18 on the left side of the flattening mechanism. At this time, the moving end of the horizontal transfer mechanism 7 and the mounting plate 8 are located on the left side of the flattening mechanism. During the processing, the moving end of the horizontal transfer mechanism 7 and the mounting plate 8 move to the right, so that the rightmost fixture 9 on the mounting plate 8 is located directly below the flattening mechanism. When the battery cover plate flattening process on the fixture 9 is completed, the moving end of the horizontal transfer mechanism 7 and the mounting plate 8 continue to move to the right, and the fixture 9 located on the left side of the mounting plate 8 falls directly below the flattening mechanism. At this time, the rightmost fixture 9 on the mounting plate 8 is picked up by the first conveying mechanism 18 on the right side of the flattening mechanism. The battery cover is transferred to the first transfer conveyor belt 2. The battery cover on the first transfer conveyor belt 2 is picked up by the suction cup of the second handling mechanism 19 and transferred to the second transfer conveyor belt 3. The second transfer conveyor belt 3 is equipped with a detection mechanism 33. The detection mechanism 33 performs surface inspection on the battery cover on the second transfer conveyor belt 3 to check whether the battery cover has problems such as uneven or irregular opening, poor consistency of terminal compression height, etc. If the battery cover fails the inspection, it is transferred to the NG conveyor belt 5 by the third handling mechanism 20. If the battery cover passes the inspection, it is transferred to the unloading conveyor belt 4 by the third handling mechanism 20, and finally the finished battery cover is output.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
