When processing photovoltaic silicon wafers, in order to improve the processing efficiency of photovoltaic silicon wafers, corresponding transplanting, transmission and suction equipment are usually used to automatically transmit photovoltaic silicon wafers.

When the electrical box works for a long time, when the heat cannot be dissipated to the outside in time, it is easy to cause the electrical components inside the electrical box to overheat. At the same time, the existing air-cooled heat dissipation method can only blow air to cool the fixed position of the electrical box due to the fixed position of the fan, thereby reducing the heat dissipation and cooling effect of the electrical box.

In order to solve this technical problem, this embodiment discloses the following technical content;

The discharging transmission module 14 includes a material picking DD motor device 141, and a material picking suction cup device 142 is arranged below the material picking DD motor device 141, a silicon wafer transplanting and transferring structure 143 is arranged on the right side of the material picking suction cup device 142, and the lower end of the silicon wafer transplanting and transferring structure 143 is fixedly connected with a bottom positioning frame 144, a guide transmission line 145 is arranged on the right side of the silicon wafer transplanting and transferring structure 143, and a lifting streamline maintenance entrance 146 is installed on the side of the guide transmission line 145, a material picking and transplanting structure 147 is installed on the right side of the lifting streamline maintenance entrance 146, and a master control air circuit valve 148 is installed at the lower end of the material picking and transplanting structure 147, a discharging transmission line 149 is installed on the side of the material picking and transplanting structure 147, and a driving motor 1410 is installed on the side of the discharging transmission line 149, and a clamping bracket 1411 is fixedly connected to the lower end of the discharging transmission line 149.

[0038] The silicon wafer enters the device from the machine silicon wafer feed port 9, and then is transferred through the conveyor belt 131. After entering the transmission sheet, the silicon wafer will pass through the silicon wafer lifting and steering device 136. The silicon wafer lifting and steering device 136 is connected to the lifting and rotating module 135 below to rotate, and the working principle of lifting up and down is performed. After the silicon wafer rotates through the negative vacuum, the unprocessed silicon wafer will be moved through the photovoltaic transplanting device 138 and the transplanting guide structure 139 and moved to the DD motor transmission docking exposure machine station.

Through the front and rear transfer transfer suction cups, the silicon wafer is sucked and placed on the rear half of the transmission line for transmission, and enters the steering transmission line through the transmission line. The final transplanting work is performed through the front and rear transfer modules equipped with vacuum suction cups, thereby performing the final transmission work on the streamline, and then the work is completed and flows out of the equipment and enters the next step of the equipment at its work station.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. When the transplanting and transmission equipment is in use, the whole machine is controlled by the internal electrical box. When the electrical box works for a long time, when the heat cannot be dissipated outward in time, it is easy to cause the electrical components inside the electrical box to overheat. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 2-Figure 5 As shown;

[0040] The heat dissipation mechanism 12 includes a filter 121 , and the filter 121 is installed on the back of the circuit and electrical cabinet 11 . The longitudinal section of the filter 121 is set to a rectangular structure, and the filter 121 is fixed to the circuit and electrical cabinet 11 by bolts.

[0041] A filter 121 is installed on the back of the circuit and electrical cabinet 11. The filter 121 allows the circuit and electrical cabinet 11 to be connected to the outside air, thereby improving the heat dissipation effect of the internal components of the circuit and electrical cabinet 11. At the same time, the filter 121 can block dust in the outside air and prevent impurities in the outside air from entering the interior of the circuit and electrical cabinet 11.

[0042] Embodiment 3: The technical content disclosed in this embodiment is a further improvement on the basis of the above-mentioned embodiments 1 and 2. The existing air-cooling heat dissipation method, because the position of the fan is fixed, can only blow air to cool the fixed position of the electrical box, thereby reducing the heat dissipation and cooling effect of the electrical box. In order to solve this technical problem, this embodiment discloses the following technical content, such as Figure 2-Figure 5 As shown;

[0043] A positioning frame 122 is fixedly connected to the circuit electrical cabinet 11, and a dual-axis motor 123 is fixedly installed in the middle of the positioning frame 122, and a reciprocating screw 124 is fixedly connected to both ends of the dual-axis motor 123, and a moving block 125 is installed on the reciprocating screw 124, and a motor is fixedly connected to the inside of the moving block 125, and a cooling fan 126 is fixedly connected to the output end of the motor. The reciprocating screw 124 and the moving block 125 are threadedly connected, and the moving block 125 is symmetrically arranged about the vertical center axis of the positioning frame 122. The moving block 125 is set as a rectangular structure, and the outer wall of the moving block 125 and the inside of the positioning frame 122 are in contact with each other, and the moving block 125 and the positioning frame 122 are slidably connected.

[0044] When the circuit and electrical cabinet 11 is working, the heat dissipation fan 126 is controlled to rotate by the internal motor of the moving block 125, and the rotation of the heat dissipation fan 126 is used to cool the inside of the circuit and electrical cabinet 11 with air, and the dual-axis motor 123 is turned on at the same time. The reciprocating screw rod 124 can be rotated by turning on the dual-axis motor 123, and the rotation of the reciprocating screw rod 124 can make the threaded moving block 125 drive the heat dissipation fan 126 to move back and forth left and right on the positioning frame 122. The reciprocating movement of the heat dissipation fan 126 can increase the blowing range of the circuit and electrical cabinet 11 and increase the heat dissipation effect of the circuit and electrical cabinet 11.

[0045] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
