Description

Technical Field

[0001] The utility model relates to the field of lithium battery production equipment, in particular to a button battery production equipment. Background Art

[0002] Lithium batteries offer advantages such as high energy consumption, long lifespan, compact size, light weight, strong adaptability to high and low temperatures, and environmental friendliness. Due to their excellent performance, they are widely used in high-demand, fast-growing sectors such as new energy vehicles and portable consumer electronics. They are also gradually expanding into other product areas, demonstrating a promising market outlook. Coin cell batteries, also known as button cells, are a common type of lithium-ion battery. These batteries are shaped like a small button, typically with a larger diameter and a thinner thickness. Due to their small size, they are particularly widely used in various microelectronic products, such as electronic watches, electronic dictionaries, electronic scales, remote controls, and cameras.

[0003] Button batteries typically consist of a casing, a battery cell, and positive and negative tabs. The cell is encapsulated within the casing, with the positive and negative tabs extending from the cell and out of the casing. Depending on the cell manufacturing process used, the positive and negative tabs can be connected on the same side or on opposite sides. However, connecting the positive and negative tabs on the same side is more conducive to improving battery production efficiency and quality.

[0004] At present, in the production process of button batteries with positive and negative tabs led out on the same side, after the battery cell winding is completed, manual operation is generally required to load the battery cell and transfer the battery cell to the ironing and folding tab station, and then the battery cell is manually placed in the mold cavity of the hot press for hot pressing and forming, and then the tabs are manually folded. Finally, the battery cells with ironed and folded tabs are manually placed one by one into the battery cell carrier at the unloading position. The whole production process is very labor-intensive, with high transportation costs and low production efficiency. In addition, due to multiple manual touches on the battery cell, there is a safety hazard of damaging the battery cell. Utility Model Content

[0043] The utility model provides a button battery production device, which can automatically iron and fold the tabs 102 (positive tab 102 and negative tab 102) of the button battery with two tabs 102 (positive tab 102 and negative tab 102) led out on the same side.

[0044] like Figure 1 As shown, the button battery production equipment includes a frame 1, on which a station turntable 2, a loading mechanism 3, a tab pre-folding mechanism 4, a battery cell ironing mechanism 5, a tab folding mechanism 6 and a unloading mechanism 8 are provided. Specifically:

[0045] The work station turntable 2 is rotatable, and a loading station, a tab pre-folding station, a cell ironing station, a tab folding station, and a blanking station are arranged circumferentially on the work station turntable 2, and a cell clamp 21 for clamping the cell 101 is provided at each of the loading station, the tab pre-folding station, the cell ironing station, the tab folding station, and the blanking station;

[0046] The feeding mechanism 3 is arranged at the feeding station. When the battery cell 101 is wound by the winding machine, the state of the button battery is as follows: Figure 2As shown, the positive electrode tab 102 and the negative electrode tab 102 of the button battery are led out on the same side of the battery cell 101, and the two tabs 102 are perpendicular to the upper end surface of the battery cell 101; then, the button battery is transported to the vicinity of the loading station through a feeding conveyor line or other conveying mechanism, and then the battery cell 101 is taken out by the feeding mechanism 3 and transported to the battery cell clamp 21 of the loading station. The above-mentioned removal can be achieved by clamping, suction and other methods;

The tab pre-folding mechanism 4 can pre-fold the positive and negative tabs 102 led out from the same side of the battery cell 101 outward by 90 degrees, so that the surfaces of the positive and negative tabs 102 are flush with the upper end surface of the battery cell 101, preparing for subsequent ironing and folding of the tabs.

After the tab pre-folding mechanism 4 pre-folds the positive and negative tabs 102 led outwards on the same side of the battery cell 101 by 90 degrees, the station turntable 2 continues to rotate and transfers the battery cell 101 to the battery cell ironing station. The battery cell ironing mechanism 5 can hot-press and iron the upper and lower end surfaces of the battery cell 101 to form the battery cell 101 into a thickness that meets the process requirements.

[0049] The tab folding mechanism 6 is arranged at the tab folding station. After the battery cell ironing mechanism 5 irons and flattens the upper and lower end surfaces of the battery cell 101, the station turntable 2 continues to rotate. When the battery cell 101 is transferred to the tab folding station, the tab folding mechanism 6 can fold the positive and negative tabs 102 of the battery cell 101 downward into an L shape, so that the surface of the tab 102 is lower than the height of the upper end surface of the battery cell 101. Figure 3 As shown;

[0050] The unloading mechanism 8 is arranged at the unloading station. When the folding ear mechanism 6 completes the folding ear process, the station turntable 2 continues to rotate. When the battery cell 101 is transferred to the unloading station, the unloading mechanism 8 can remove the battery cell 101 from the battery cell fixture 21 of the unloading station and transport it to the collection box.

[0051] The button battery production equipment adopting the above structure is equipped with a work station turntable 2, a loading mechanism 3, a tab pre-folding mechanism 4, a battery cell ironing mechanism 5, a tab folding mechanism 6 and a unloading mechanism 8 on the frame 1, and the work station turntable 2 can rotate, which can realize automatic loading, automatic ironing, automatic tab folding and automatic unloading during the button battery ironing and tab folding process, reducing manual participation in the production process, reducing transportation costs, and improving production efficiency.

In this embodiment, the tab detection mechanism 7 is a CCD detection mechanism, which uses the CCD to capture the position and angle of the cell tab 102. Of course, other detection components can also be used.

[0053] The button battery production equipment adopts the above structure, by setting an inspection station between the tab folding station and the unloading station, and setting a tab detection mechanism 7 at the inspection station. After the tab folding mechanism 6 completes the tab folding process, the station turntable 2 continues to rotate, and when the battery cell 101 is transferred to the inspection station, the tab detection mechanism 7 can detect whether the position, angle, etc. of the tab 102 are qualified, and store qualified battery cells 101 and defective battery cells 101 separately according to the inspection results, which can further improve the production quality of button batteries.

[0054] In some embodiments, as Figure 4 、 Figure 7 As shown, the workstation turntable 2 also includes a first rotating assembly 22 and a turntable body 23. The cell clamps 21 are circumferentially arranged on the turntable body 23 and are used to clamp the cell 101. The turntable body 23 can rotate horizontally under the drive of the first rotating assembly 22. In this embodiment, the first rotating assembly 22 is composed of a servo motor and a divider, and the servo motor drives the divider to rotate at high speed. The cell clamp 21 is composed of a cell chuck and a clamping cylinder, and the clamping cylinder controls the opening and closing of the cell chuck. Of course, the cell clamp 21 and the first rotating assembly 22 can also be implemented with other structures, as long as they can achieve the effect of clamping the cell 101 and driving the turntable body 23 to rotate.

[0055] The button battery production equipment adopts the above structure, and the work station turntable 2 is composed of a battery cell clamp 21, a first rotating component 22, and a turntable body 23.

The loading detection assembly 34 can detect the position and angle of the tab 102 in the loading chuck 31, and the second rotation assembly 35 can control the horizontal rotation of the loading chuck 31. In this embodiment, the loading detection assembly 34 is a CCD detection mechanism that uses the CCD to capture the position and angle of the battery cell tab 102. Of course, other detection assemblies can also be used.

[0059] In the button battery production equipment adopting the above structure, after the loading chuck 31 clamps the battery cell 101, the position and angle of the battery cell tab 102 can be detected by the loading detection component 34, and the second rotating component 35 then corrects the tab 102 to the initial position according to the set tab 102 calibration position and angle, so as to more accurately perform subsequent tab pre-folding, battery cell ironing, tab folding and other processes, thereby further improving production efficiency and quality.

[0062] In some embodiments, the tab pre-folding mechanism 4 further includes a third rotating assembly 44 , and the third rotating assembly 44 can control the two leveling levers 41 to rotate horizontally.

[0063] The button battery production equipment adopting the above structure adds a third rotating component 44 in the tab pre-folding mechanism 4. When the positive and negative tabs 102 of the battery cell 101 are not arranged relative to each other at 180°, but at other angles (for example, the positive and negative tabs 102 of the battery cell 101 in this embodiment are arranged at 90°), the third rotating component 44 can be used to control the push-flattening lever 41 to rotate horizontally to the corresponding position to pre-fold the tabs, thereby expanding the scope of application of the equipment.
