Technical Field

[0002] A battery is an energy storage device that can store electrical energy. A battery generally refers to a cup, trough, or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. Now it also refers to a small device that can generate electrical energy. Common energy storage batteries include lithium-ion batteries, sodium-ion batteries, lead-acid batteries, nickel-metal hydride batteries, supercapacitors, etc. In the process of producing cylindrical batteries, the battery core is formed into a cylindrical shape by winding. After the battery core is wound, it is necessary to tape the end of the battery core and attach the tape around the end of the battery core to prevent the tab part of the battery core from contacting the aluminum shell and avoid short circuits. In the traditional operation process, the tape is generally held manually, wrapped around the tape and attached to the end of the battery core, but the manual operation is inefficient, the positioning is inaccurate, and the consistency is not high. Now there are some simple mechanisms that can assist in providing tape, but they still need to rely on manual operation.

In this embodiment, the second driving member 522 is a cylinder. When the second driving member 522 drives the rotating clamping member 521 to rotate, the rotating clamping member 521 and the fixed block 53 cooperate to clamp the adhesive tape.

[0026] The movable plate 51 is provided with a connecting block 55, and the first driving member 54 is provided on the connecting block 55. In addition, in this embodiment, an elastic reset member can be connected between the rotating clamping member 521 and the connecting block 55, and the elastic reset member can assist the rotating clamping member 521 to reset.

[0027] The cell positioning and rotating mechanism 1 includes a base 11, a lifting assembly 12 movably connected to the base 11, a cell positioning assembly 13 connected to the lifting assembly 12, and a rotating drive assembly 14 disposed on the lifting assembly 12 for driving the cell positioning assembly 13 to rotate; the cell positioning assembly 13 includes a rotating seat 131 connected to the lifting assembly 12, a clamping claw cylinder 132 connected to the rotating seat 131, and a clamping member 133 connected to the output end of the clamping claw cylinder 132.

The piston rod of the pulling cylinder 44 and the sliding block 42 are not fixedly connected, but only contact with the sliding block 42 when extended to push the sliding block 42, and then reset. When the piston rod of the pulling cylinder 44 is extended, the sliding block 42 is pushed, so that the pulling wheel 43 pulls the tape and pulls the tape out of the supply tray 32 for a certain length, so that when the battery cell rotates, the pulled tape is attached to the battery cell around it.

[0035] During specific operation, the conveyor line of the cylindrical battery production line passes through the gap between the base 11 and the fixed plate 2. When one of the battery cells reaches the preset position, the lifting assembly 12 descends, and the clamping cylinder 132 of the battery cell positioning assembly 13 clamps the battery cell and then rises. After the battery cell reaches the gluing position, the first driving assembly pushes the moving plate 51 to move, and the end of the tape is attached to the battery cell. At this time, the rotating driving assembly 14 drives the clamping cylinder 132 to rotate, and the tape is attached to the end of the battery cell.

The tightening cylinder 72 presses the battery cell from both sides, the clamping assembly 52 clamps the tape, and the movable plate 51 is reset under the drive of the first driving member 54. At this time, the contact between the tape and the tool 6 is cut off, and the rotating driving assembly 14 drives the clamping claw cylinder 132 to rotate for a certain period of time again, so that the end of the tape is pressed onto the battery cell by the first clamping cylinder 71 and the second clamping cylinder 72. After that, the first clamping cylinder 71 and the second clamping cylinder 72 are reset, the lifting mechanism descends, and the battery cell is placed back on the conveying line and then rises.
