Description

Technical Field

[0001] The present invention relates to the technical field of automated cutting of photovoltaic cells, and in particular to automated cutting and separation equipment for photovoltaic cells. Background Art

[0002] The Chinese patent with the announcement number CN106847993B discloses an automated cutting and separation device for photovoltaic cells. The technology includes a feeding device, a laser cutting device, a conveying device, a transverse breaking device, a longitudinal breaking device and a separating device. The feeding device transfers the stacked cells to a position, and then uses the laser beam generated by the laser cutting device to perform transverse and longitudinal grooves on the surface of the cells. The grooved cells are conveyed to the transverse breaking device by the conveying device. The transverse oblique folding portion of the transverse breaking device has a long axis and can be selectively unfolded into a plane and obliquely folded at an angle. The longitudinal breaking device includes at least two longitudinal oblique folding portions, and there is a rotating shaft at the junction of the two adjacent longitudinal oblique folding portions, and the axial direction of the rotating shaft is parallel to the conveying direction. At least one longitudinal oblique portion can be selectively unfolded into a plane and obliquely folded at an angle with the rotating shaft as the axis. The separating device is located on the downstream side of the longitudinal breaking device, and the two adjacent conveyor belts are at an angle to completely separate the cell units to different storage positions. This technology replaces the existing process that uses a lot of manual labor and adopts fully automated equipment, thereby significantly reducing labor costs and improving output and production efficiency. However, the above technology still has problems during use due to structural limitations:

[0003] The conventional laser scribing technology on the market is mainly based on laser ablation combined with mechanical breaking technology. First, a cutting line is processed on the back of the battery through the surface, and then the battery is mechanically broken along the cutting line. However, when laser ablation is used to separate multiple rectangular single-piece solar cells of different specifications from a whole rectangular photovoltaic cell, as shown in the following figure, Figure 8 As shown, attached Figure 8 In the process, a whole rectangular photovoltaic cell is divided into 7 rectangular single pieces of different specifications. Since the horizontal and vertical sides of the rectangular single pieces of different specifications are connected to each other, if a mechanical breaking method is used directly, it is difficult to control the breaking force, and the breaking groove of one rectangular single piece may easily extend into other rectangular single pieces, causing damage to other rectangular single pieces. Therefore, the above technology is not conducive to dividing multiple rectangular single-piece batteries of different specifications. Summary of the Invention

Therefore, the entire rectangular battery can only be clamped at the right angles.

Figure 8 and attached Figure 10 As shown, in order to change the specifications of the single cell after cutting;

[0069] After the first L-shaped cutting blade 2 completes the horizontal or vertical movement, the output end of the first cylinder 8 is activated to retract, and the output end of the first cylinder 8 drives the moving chamber 9 to move downward in the vertical slot 7, so that the cutting edges of the lower ends of the first L-shaped cutting blade 2 and the second L-shaped cutting blade 3 cut the photovoltaic cell, and divide the entire photovoltaic cell into multiple rectangular cells of different specifications;

[0070] It is particularly noted that when the first L-shaped cutting knife 2 and the second L-shaped cutting knife 3 cut the entire photovoltaic cell sheet, due to the movement of the horizontal or vertical sides of the first L-shaped cutting knife 2, there is a gap between the two first L-shaped cutting knives 2, so there are connection points between multiple cells of different specifications. At this time, the output end of the horizontal cylinder 12 is started to reciprocate and extend, and the output end of the horizontal cylinder 12 drives the mobile cutting knife 6 to slide back and forth in the middle end slide groove 11 to cut off the connection points of different cell sheets.
