Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment manufacturing, in particular to a cell slice scribing and stepping transport platform. Background Art

[0002] Before the cells are welded together into strings, a laser beam is used to separate the entire cell into at least two pieces. Traditionally, this process involves moving the entire cell onto a dicing platform, which then moves the cell through the laser beam along a cutting path, thereby separating the cell. However, with the rapid development of the photovoltaic industry, the efficiency of cell dicing and handling is increasing. Therefore, a dicing platform that can improve this efficiency is needed. Utility Model Content

[0003] In view of the problems in the prior art, the purpose of the present invention is to provide a battery cell slicing and stepping transport platform, which can improve the efficiency of battery cell slicing and transport.

[0004] The battery cell slicing step-by-step transport platform includes a slicing platform and a power device. The slicing platform is fixedly installed at the output end of the power device. The power device drives the slicing platform to perform transporting movements. The battery cell slicing step-by-step transport platform also includes an extended supporting bar. The extended supporting bar is installed on the slicing platform. The extended supporting bar is divided into a whole-piece extended supporting bar and a slice extended supporting bar. The whole-piece extended supporting bar is provided with at least one transport part, and the slice extended supporting bar is provided with at least two transport parts.

[0005] The extended supporting bars installed on the dicing platform can not only transport the whole battery cell at the incoming material station to the dicing station, but also transport the diced battery cell from the dicing station to the slicing station. Furthermore, the battery cell that has been sliced ​​in the slicing unit can be transported to the inspection station, which saves the transportation equipment between the stations and transports the battery cells of 3 stations at the same time, thereby improving the efficiency of battery cell slicing and transportation.

[0006] Specifically, the transport portion on the entire extended supporting strip is configured as a suction head, and a negative pressure cavity is provided inside the entire extended supporting strip, and the negative pressure cavity is communicated with the suction head.

[0007] The transporting part configured as a suction head on the entire extended supporting bar can not only stably adsorb and transport the entire battery cell, but also prevent the entire battery cell from falling during the process of being transported to the dicing station.

[0008] Specifically, the two transport portions of the segmented extension support strip are provided with first adsorption holes, and a negative pressure cavity is provided inside the segmented extension support strip, and the negative pressure cavity is communicated with the first adsorption holes.

[0009] The first adsorption hole arranged on the extension carrying strip can adsorb the battery piece on the extension carrying strip during the carrying process, preventing the battery piece from falling off.

[0010] Specifically, the whole piece extension carrying strip and the piece extension carrying strip are both provided with at least two and are parallel to each other.

[0011] The at least two whole piece extension carrying strips and the at least two piece extension carrying strips can ensure the stability of the battery piece carrying.

[0012] Specifically, the upper surface of the piece platform is provided with at least eight second adsorption holes which are distributed in at least four rows at equal intervals, and the piece platform is internally provided with a negative pressure cavity which is communicated with the second adsorption holes.

[0013] The second adsorption holes arranged on the piece platform can form a stable adsorption force on the plane of the whole piece battery piece, so that the whole piece battery piece will not be displaced by the laser or the equipment during the scribing process, and the problems such as scribing defects can be avoided.

[0014] Specifically, the battery piece scribing step carrying platform further comprises a waste liquid collecting box which is installed on the side of the scribing platform.

[0015] The waste liquid collecting box arranged on the side of the scribing platform can collect the waste liquid generated during the laser scribing process, preventing the waste liquid from flowing into the equipment and causing the service life of the equipment to be sharply reduced.

[0016] Specifically, the power device comprises a horizontal power assembly and a lifting power assembly, the fixed end of the lifting power assembly is connected with the movable end of the horizontal power assembly, and the scribing platform is connected with the movable end of the lifting power assembly.

[0017] The horizontal power assembly and the lifting power assembly of the power device can carry the scribing platform in the horizontal and vertical directions.

[0018] Specifically, the lifting power assembly comprises an eccentric wheel assembly and a power structure, and the power structure drives the eccentric wheel assembly to perform lifting action.

[0019] The eccentric wheel assembly arranged on the lifting power assembly can realize lifting reciprocating motion by driving the eccentric wheel assembly through the power structure, and compared with other transmission devices, the structure is simple, the failure rate is low, the reliability is high, and the practical space of the equipment can be saved.

[0020] In summary, the extended support bar installed on the dicing platform can not only transport the whole battery cell at the incoming station to the dicing station, but also transport the diced battery cell from the dicing station to the slicing station. Furthermore, the battery cell that has been sliced ​​in the slicing unit can be transported to the inspection station, saving the transport device between each station and transporting the battery cells of three stations at the same time, thereby improving the efficiency of battery cell slicing and transportation. The transport portion provided as a suction head on the whole-piece extended support bar can not only stably adsorb and transport the whole battery cell, but also prevent the whole battery cell from falling during the transportation to the dicing station. The first adsorption hole provided on the slicing extended support bar allows the diced battery cell to be adsorbed on the slicing extended support bar during the transportation process, preventing it from falling during the transportation process. The stability of the battery cell transportation can be ensured by providing at least two whole-piece extended support bars and slicing extended support bars respectively. By distributing the second adsorption holes on the scribing platform in at least four rows with equal spacing, a stable adsorption force can be formed on the plane of the entire battery cell, ensuring that the entire battery cell will not be displaced by the laser or equipment when being scribed at the scribing station, thus avoiding problems such as poor scribing. The waste liquid collection box provided on the side of the scribing platform can collect the waste liquid generated during the laser scribing process to prevent the waste liquid from flowing into the equipment and causing a sharp reduction in the service life of the equipment. The slicing platform can be transported in the horizontal and vertical directions by the translational power assembly and the lifting power assembly provided by the power device. The eccentric wheel assembly provided by the lifting power assembly can be driven by the power structure to realize lifting and reciprocating motion. Compared with other transmission devices, it not only has a simple structure, a low failure rate, and high reliability, but also saves practical space for the equipment.
