Description

Technical Field

[0001] The utility model belongs to the technical field of battery cell production and preparation, and in particular relates to a battery cell and separator paper taking, placing and conveying device. Background Art

[0002] With the rapid development of new energy and the improvement of people's living standards, solar cells have been widely used in daily life and industrial production, and their application fields and forms are becoming more and more diverse.

[0003] BC cell, the full name is "full back electrode contact (full reverse electrode contact) crystalline silicon photovoltaic cell". BC cell adopts a design different from traditional crystalline silicon photovoltaic cells. Its electrode is located on the back of the cell, which means that the front is fully exposed to sunlight, improving the light absorption efficiency. This solar cell with full back electrode setting can also reduce the path of current transmission, significantly reduce the resistance of the cell, and thus improve the performance of the cell.

[0004] However, since the front of the BC battery needs to receive and convert solar energy, the front of the BC battery is usually fragile. During the production and transportation process, it is easy to get scratched on the front of the BC battery, which in turn affects the working efficiency of the BC battery. In order to avoid scratches on the front of the BC battery caused by the relative movement between two adjacent BC battery sheets during transportation and storage of two stacked BC batteries, it is usually necessary to place a separator between the two battery sheets to separate the two adjacent BC batteries.

[0005] In the prior art, a conveyor belt is usually used to transport the battery cells, and an automated robotic arm is used to place the separator paper on top of the battery cells. After the separator paper is added to the battery cells, due to the non-fixed relative position between the separator paper and the battery cells, if the offset between the separator paper and the battery cells is large, some of the battery cells will leak out, which not only cannot completely avoid scratches on the battery cells, but also requires the position of the separator paper to be rearranged during the packaging process, affecting the production efficiency of the battery cells.

The three-axis moving component 21 absorbs the paper spacer through the paper spacer suction cup 22 on the moving end, and drives the paper spacer suction cup 22 to move in the space through the moving end, and then transports the paper spacer to the top of the battery cell. Thereafter, the paper spacer suction cup 22 releases the adsorption of the paper spacer, so that the paper spacer can accurately cover the top surface of the battery cell.

[0045] It is worth noting that in the preferred embodiment of the present application, the direction in which the synchronous belt extends is the Y-axis direction, the direction perpendicular to the Y-axis in the horizontal plane is the X-axis direction, and the direction perpendicular or plumb to the horizontal plane is the vertical direction, that is, the Z-axis direction.

The rotating motor is fixedly mounted on the mounting surface so that the rotating shaft of the rotating motor can rotate around the Z axis. At least one battery cell suction cup 33 is arranged at both ends of the horizontally arranged rotating arm 32, and the center position of the rotating arm 32 is fixedly connected to the rotating shaft, so that the battery cell suction cups 33 at both ends of the rotating arm 32 can be aligned with the battery cell conveying mechanism 4 and the synchronous belt, respectively, so as to stably transfer the battery cells on the battery cell conveying mechanism 4 to the limited space of the synchronous belt. Preferably, the rotating motor adopts a stepping motor to improve the accuracy of the rotation control of the rotating arm 32. Further preferably, the relative distance between the horizontally arranged battery suction cup and the top surface of the synchronous belt in the Z-axis direction is small, and preferably, the distance between the two in the Z direction is greater than 0 mm and not greater than 5 mm. In actual use, by minimizing the relative distance between the battery suction cup and the top surface of the synchronous belt in the Z-axis direction, after the battery cell is transported by the rotating arm, the free fall distance between the battery cell falling off the battery suction cup and the synchronous belt is as short as possible, ensuring that the position deviation of the battery cell will not be too large during the falling process and can be normally transferred to the limited space of the synchronous belt.
