[0032] like Figure 4As shown, the guide device 47 includes a first guide seat 471, a second guide seat 474, a first slider 472, a second slider 475 and a first linear guide rail 473.

[0033] like Figures 4 to 7 As shown, the rotating device 46 includes a flip seat 464, a flip shaft 463, a bearing seat 462 and a flip motor 461. The flip motor 461 and the bearing seat 462 are both fixed on the frame 1.

One of the flip shafts 463 is also connected to the flip motor 461. The flip motor 461 is a worm gear reduction motor, which is used to drive the first belt conveyor line 43 and the second belt conveyor line 44 to flip 180 degrees.

The clamping cylinder 481 is symmetrically fixed on both sides of the first belt conveyor line 43; the clamping seat 482 is symmetrically fixed on both sides of the second belt conveyor line 44 and connected to the piston rod of the clamping cylinder 481. The clamping cylinder 481 drives the second belt conveyor line 44 to clamp the junction box onto the first belt conveyor line 43.

[0035] like Figures 4 to 7 As shown, the first belt conveyor line 43 and the second belt conveyor line 44 have the same structure. The first belt conveyor line 43 includes a first conveyor frame 431, a first conveyor roller 432, a second conveyor roller 433 and a conveyor belt 444. A deformation groove 435 is also provided in the middle of the first conveyor frame 431. The first conveyor roller 432 and the second conveyor roller 433 are both installed at both ends of the first conveyor frame 431. The conveyor belt 444 is sleeved on the first conveyor roller 432 and the second conveyor roller 433; at least one of the first conveyor roller 432 and the second conveyor roller 433 is a power roller. The deformation groove 435 is used to prevent the terminal box from being crushed when the terminal box is pressed. The structures of the first feeding belt conveyor line 31, the first discharging belt conveyor line 32, the second feeding belt conveyor line 33 and the second discharging belt conveyor line 34 can also be the same as the first belt conveyor line 43.

[0036] like Figures 8 to 10 As shown, the discharge device 8 includes a rotating cylinder 81, a discharge plate 82 and a clamping device 83. The rotating cylinder 81 is installed at one end of the frame 1. The turntable of the rotating cylinder 81 is connected to the discharge plate 82 and is located at the center of the discharge plate 82. The clamping device 83 is symmetrically installed at both ends of the discharge plate 82. The clamping device 83 is used to clamp the junction box. The clamping device 83 includes a clamping finger cylinder 831 and a clamping block 832. The clamping finger cylinder 831 is installed on the discharge plate 82 and is located below the sliding groove 821 of the discharge plate 82. The width of the sliding groove 821 is smaller than the length of the junction box. The clamping block 832 is fixed on the clamping finger cylinder 831 and is movably inserted into the sliding groove 821. The clamping block 832 is provided with a clamping groove 833, so that the two ends of the clamping block 832 are pressed against the two sides of the junction box, thereby improving the reliability of pressing the junction box.

[0037] During operation, the first robot arm 21 respectively picks up the junction boxes on the positive electrode feeding device and the negative electrode feeding device through the first clamping claw, and moves to the bottom of the feeding camera 61. The feeding camera 61 takes a picture to identify the state of the junction box, that is, to identify the front and back sides of the junction box, and then places the identified positive junction box on the first feeding belt conveyor line 31, and places the identified negative junction box on the second feeding belt conveyor line 33. For the positive junction box, if the front side of the positive junction box faces upward, it passes through the first belt conveyor. After the wire is fed 43, it enters the first discharging belt conveyor line 32, and then the first camera 63 detects whether the positive terminal box is facing up. If the positive terminal box is facing up, the second robot arm 22 clamps the positive terminal box through the second clamp and places it on the first discharging device 8. When the positive terminal box is placed on the discharging plate 82, the clamping finger cylinder 831 drives the clamping block 832 to clamp the positive terminal box, and then the rotating cylinder 81 drives the discharging plate 82 to rotate 180 degrees, so that the positive terminal box is rotated to the installation position. If the positive terminal box detected by the feed camera 61 is facing up, when the positive terminal box enters the middle position of the first belt conveyor line 43, the first belt conveyor line 43 stops, and then the piston rod of the pressing cylinder 481 retracts, and the second belt conveyor line 44 presses the positive terminal box on the first belt conveyor line 43, and then the flip motor 461 is started, and the flip motor 461 flips the first belt conveyor line 43 to the top, and then the piston rod of the pressing cylinder 481 extends, so that the second belt conveyor line 44 is flush with the first feed belt conveyor line 31 and the first discharge belt conveyor line 32, and then the second belt conveyor line 44 is started to convey the positive terminal box facing up after flipping to the first discharge belt conveyor line 32. If the positive terminal box detected by the first camera 63 faces up, the second robot arm 22 does not work, so that the positive terminal box falls from the end of the first discharge belt conveyor line 32 into the turnover box below. The first camera 63, the second camera 62 and the third camera 64 ensure that the junction box facing upward enters the discharge device 8. The feeding process of the negative electrode junction box is the same as the feeding process of the positive electrode junction box.

[0038] The step loading device 5 delivers the intermediate wiring box to the interior of the tray 50 through the discharge port 52. The third camera 64 detects the intermediate wiring box in the tray 50 and sends the coordinates of the intermediate wiring box facing up to the second robot arm 22. The second robot arm 22 grabs the intermediate wiring box facing up and then places the intermediate wiring box on the discharge device 8.

[0039] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
