Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device for photovoltaic panels of a photovoltaic prefabricated cabin. Background Art

[0002] Currently, the laser cutting devices in the prior art generally consist of a three-axis moving mechanism, a laser cutting assembly, and a support frame. During operation, the operator needs to first place the photovoltaic panel to be cut on the surface of the support frame. After positioning and fixing, the three-axis moving mechanism is controlled to drive the laser cutting assembly to perform cutting along a preset path. After the processing is completed, the finished product is then removed manually by the operator. There are multiple technical problems in this process: First, the high-temperature molten slag generated during the cutting process is likely to splash onto the surface of the cutting table and form an iron slag adhesion layer after cooling and solidification. Long-term accumulation will significantly reduce the support accuracy and flatness of the cutting table, forcing the operator to interrupt the operation for cleaning after each cutting, seriously restricting continuous production; Second, the high-temperature molten slag and the residual heat on the cutting table surface increase the safety risk of the loading and unloading operation. The operator not only faces the risk of scalding, but also may cause personal injury if accidentally touching the equipment start button and the laser assembly runs unexpectedly; Third, in order to adapt to the cutting requirements of large-sized photovoltaic panels, the existing support frames are often large, resulting in a sharp increase in the overall floor area of the equipment. In the limited space environment of the workshop, it not only increases the difficulty of site management, but also is not conducive to the flexible storage of the equipment.

And through the transmission connection between the active transmission component 209 and the cooling component 210, the cooling effect of the photovoltaic panels is remarkable. This method can form a processing system, and the structures are interrelated with each other, which can effectively optimize the cooling and cleaning effects, reduce the processing difficulty, and meet the requirements of automatic processing operations, so as to ensure the continuous laser cutting operation.

[0027] Working principle: When performing the cutting operation of the photovoltaic panel, the photovoltaic panel is placed on the guiding roller 2022 and transported to the sawtooth blade 211 along the guiding roller 2022. And the photovoltaic panel moves onto the limiting transmission belt 2061. The limiting transmission belt 2061 limits the photovoltaic panel. When the photovoltaic panel moves to the cutting area, at this time, the laser cutting device 100 performs the cutting operation; When it is necessary to push for photovoltaic panel cutting, the motor 2081 drives the rotation of the driving shaft 2083, the driving shaft 2083 drives the rotation of the driving wheel 2084, and under the driving action of the conveyor belt 2085, the driven wheel 2086 rotates. At this time, the conveyor belt 2085 drives the saw blade 211 to rotate, enabling the saw blade 211 to convey the photovoltaic panel, and further enabling the photovoltaic panel to perform a moving cutting operation. Moreover, the driving shaft 2083 also drives the rotation of the first bevel gear 2091. The first bevel gear 2091 is in transmission connection with the second bevel gear 2092, the second bevel gear 2092 drives the rotation of the rotating shaft 2094, the rotating shaft 2094 drives the rotation of the third bevel gear 2095, the third bevel gear 2095 is in transmission connection with the fourth bevel gear 2102, the fourth bevel gear 2102 drives the rotation of the fan shaft 2104, and the fan shaft 2104 drives the rotation of the fan structure 2103. The fan structure 2103 accelerates the air flow velocity, and thus the cooling operation can be carried out; When cleaning is required, the saw blade 211 is conveyed through the conveyor belt 2085 for movement. And the driven shaft 2087 drives the rotation of the brush shaft 2031 through the belt drive structure 2033. The brush shaft 2031 drives the rotation of the roller brush 2032. The roller brush 2032 can clean the passing saw blade 211. The cleaned saw blade 211 is conveyed upward. Moreover, the water pump 2071 pumps the liquid inside the water tank 201, enabling the liquid to be conveyed through the delivery pipe and sprayed out through the nozzle group 2073, so that the liquid is sprayed onto the saw blade 211 for flushing and cooling. After cooling, it cooperates with the fan structure 2103 to better perform the cooling operation on the photovoltaic panel and the saw blade 211. In this way, the cooling and cleaning operations can be carried out cyclically.
