In this embodiment, the working process of the five-grid photovoltaic cell string welding equipment is as follows:

S1. Manually stack the photovoltaic cells on the four trays 102 of the turntable feeding mechanism 1. Since the four-station turntable 101 has only one pick-up station connected with the manipulator, the remaining three stations are idle. state, the idle time of these three stations can be used to stack the photovoltaic cells on the corresponding tray 102, and when the photovoltaic cells on the pick-up station are exhausted, the stations can be switched by rotating the turntable to make the photovoltaic cells fully loaded The tray 102 cut into the reclaiming station, the tray 102 on the original reclaiming station is then cut out to the idle station to place photovoltaic cells, and the uninterrupted supply of raw materials on the reclaiming station is guaranteed by the above method.

In addition to the above-mentioned methods, the turntable feeding mechanism 1 can also perform circular feeding, specifically put different photovoltaic cells on the four trays 102, and the four-station turntable 101 continuously rotates in steps to make the four trays 102 work. The three trays 102 are switched to the pick-up station in a continuous cycle, so that the four types of photovoltaic cell pieces are serially welded together in order to realize patchwork welding.

S2. The lifting manipulator 202 in the manipulator mechanism 2 slides along the direction of the turntable feeding mechanism 1 and aligns one of the lifting manipulators 202 with the reclaiming station of the four-station turntable 101, and the other lifting manipulator 202 is aimed at the transfer platform 3. Then the lifting manipulator 202 descends under the drive of the manipulator lifting cylinder 2022 until the two lifting manipulators 202 use their vacuum suction cups 2023 to respectively suck up the pick-up station and the photovoltaic cells on the transfer platform 3, and then the two lifting manipulators 202 jointly Driven by the transmission screw 203 and the manipulator traversing motor 204, it traverses in reverse until the two manipulators are respectively aligned with the welding mechanism 8 and the transfer platform 3, and finally the lifting manipulator 202 descends and puts down the photovoltaic cells.

S3. After the photovoltaic cells are placed on the transfer platform 3, the transfer platform main body 301 and the sliding platform 302 are driven by the X-axis correction cylinder 304 and the Y-axis correction cylinder 305 to slide along the X-axis and Y-axis directions until the transfer platform The photovoltaic cell on the main body 301 is in conflict with the X-direction positioning baffle 3031 and the Y-direction positioning baffle 3032, thereby completing the positioning of the photovoltaic cell, so that the photovoltaic cell is accurately positioned at the predetermined position; The cells are preheated to prevent the excessive deformation of the photovoltaic cells caused by the excessive instantaneous temperature rise during welding.

S4. After the welding ribbon is released from the unwinding mechanism 4, the flux is coated on the surface of the welding ribbon through the welding aid mechanism 6, and then the welding ribbon can be pulled out by the pulling mechanism 5, and the welding ribbon is laid on the welding surface. On the platform 802 and the photovoltaic cells, when pulling out, the support traverse motor drives the horizontal screw 504 of the pull belt mechanism to rotate so that the clamp support 503 moves to the front end and drives the clamp 501 to clamp the ribbon head through the clamping cylinder 502 , and then the traversing motor drives the horizontal screw 504 of the tape-drawing mechanism to reversely rotate, so that the soldering tape moves backward with the chuck support 503 and lays it on the welding platform 802 and the photovoltaic cells.

S5. Whenever the ribbon pulling mechanism 5 pulls out the ribbon to the end of its stroke, a section of each ribbon is laid on the upper surface of one of the photovoltaic cells, and the other ribbon is laid on the surface of the welding platform 802 and is placed on the surface of the welding platform 802 by another A photovoltaic panel is pressed below it; then the input end pressure welding strip group 604 and the output end pressure welding strip group 605 in the welding aid mechanism 6 press the welding strip, and the cutter of the welding strip cutting mechanism 7 is driven by the lower cutting cylinder The lower cutting cuts off the welding ribbon. During the cutting process, the input-end pressure-welding belt group 604 and the output-end pressure-welding belt group 605 play a role in fixing the welding belt and removing stress, preventing the welding belt from deviating from the position and deformation.

S6. The photovoltaic cells are fixed in the welding platform 802 by the vacuum adsorption holes on the fixed area 8021 and the material transfer block 8022, and the photovoltaic cells are preheated by the secondary heating module built in the fixed area 8021; The lifting welding head 801 in the welding mechanism 8 descends and exposes under the drive of the screw rod, so that the welding ribbon is melted by high temperature to bond adjacent photovoltaic cells.

S7. After each welding of the photovoltaic cells is completed, the material transfer block 8022 will drive the photovoltaic cells on the welding platform 802 to lift and move horizontally, so that the photovoltaic cells move forward by one station. In this embodiment, the moving block 8022 is driven by the movable support rod 901 of the feeding mechanism 9 to carry out the action of jacking up and moving laterally. Because there is a vacuum release hole 8023 in the fixed area 8021, when the vacuum adsorption hole in the fixed area 8021 stops vacuum adsorption, the air can enter the chamber of the vacuum adsorption hole from the vacuum release hole 8023, so that the pressure in the chamber can quickly balance with the outside world , so as to eliminate the adsorption effect of the vacuum adsorption holes in the fixed area 8021 on the photovoltaic cells, ensure that the photovoltaic cells can be smoothly transported forward by the moving block 8022 in the way of jacking and lateral movement, and improve the efficiency of production and processing, and less The damage caused by incomplete elimination of the adsorption of the vacuum adsorption holes in the fixing area 8021 during the transportation of the photovoltaic cells.

S8. The feeding mechanism 9 transports the photovoltaic cells by lifting and moving horizontally. The specific process is as follows: the cam drive motor 909 drives the cam 908 to rotate, and the cam 908 is used to periodically lift the lifting slide 906 so that the transmission The rod and the material shifting block 8022 are lifted to lift the photovoltaic cells, and at the same time, the lateral movement drive motor 905 drives the synchronous belt to run and drives the horizontal sliding seat 903 to slide along the horizontal guide rail 902, and the transmission rod and the material moving block 8022 move laterally with the horizontal sliding seat 903. And drive the photovoltaic cells to move forward, and transport the photovoltaic cells forward through the above method.

S9. Utilize the retrieving mechanism 10 to take out the photovoltaic cell sheets welded in series from the feeding mechanism 9 and place them on the collecting platform 1007 for stacking. The specific process is as follows: first, the retrieving head 1001 is turned over and driven by the turning motor 1002 Flip down so that the side with the vacuum adsorption hole faces down, and then the movable support bar 901 of the feeding mechanism 9 is driven by the cam 908 to lift up so that the photovoltaic cells that have been welded in series are close to the flipping pick-up head 1001, and the flipping pick-up The head 1001 sucks up the photovoltaic cells through vacuum adsorption and flips them over to align them with the lower part of the lifting head 1003. The lifting head 1003 is driven down by the lifting cylinder 1004 until it clings to the photovoltaic cells. , and then lift the pick-up head 1003 to suck up the photovoltaic cells and lift it up under the drive of the lift cylinder 1004 of the pick-up head, and then move the pick-up head 1003 to the top of the collection platform 1007 driven by the lift cylinder 1006 of the pick-up head, and finally The lifting and retrieving head 1003 is moved down and the vacuum adsorption is cancelled, so that the photovoltaic cells are transferred to the collecting platform 1007 .
