Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-3 shown, a preferred embodiment of the present invention provides a main traction lifting device for a soldering tin machine, which is used on a soldering tin machine for traction of photovoltaic welding tapes. The lifting device mainly includes components such as a device body 1, a lifting module 8, a sliding seat 11, a main traction wheel 2, a drive mechanism 5, a guide wheel 4, a reversing wheel 3, and an air duct plate 6. Among them, the lifting module 8 is vertically and fixedly installed inside the device body 1. The lifting module 8 adopts a motor-screw drive to control the combined structure of the main traction wheel 2 - guide wheel 4 - reversing wheel 3 to move up and down together.

[0030] The sliding seat 11 is fixedly installed on the lifting module 8. The drive mechanism 5 is composed of a servo motor 51 and a reducer 52. The output end of the servo motor 51 is in transmission connection with the input end of the reducer 52. The output end of the reducer 52 is in transmission connection with the main traction wheel 2. The reducer 52 is fixedly installed on the sliding seat 11. During operation, the servo motor 51 drives the main traction wheel 2 to rotate to traction the movement of the photovoltaic welding tape.

[0031] Refer to Figure 2, a first connecting member 9 is fixed to the lower side of the sliding seat 11 by bolts. A second connecting member 10 is connected to the lower end of the first connecting member 9. A plurality of strip holes are formed in the second connecting member 10, and bolts are arranged in the strip holes. The second connecting member 10 is perpendicular to the first connecting member 9 and is fixed by bolts. The reversing wheel 3 is rotatably connected to the first connecting member 9, and the guide wheel 4 is rotatably connected to the second connecting member 10. The horizontal position of the second connecting member 10 can be adjusted through the strip holes so as to adjust the distance between the guide wheel 4 and the reversing wheel 3.

[0032] When the wire needs to be changed, the lifting module 8 can be used to control the main traction wheel 2, the guide wheel 4 and the reversing wheel 3 to move downward together. Then, the photovoltaic welding tape is manually passed through the guide wheel 4, and then successively through the main traction wheel 2, the reversing wheel 3, and the main traction wheel 2. That is to say, the photovoltaic welding tape will be wound around the main traction wheel 2 twice.

[0033] Reference Figure 4 , the guide wheel 4, the main traction wheel 2 and the reversing wheel 3 are arranged in a staggered manner in sequence from the inner side to the outer side of the device body 1. In this way, the two photovoltaic welding tapes wound around the main traction wheel 2 will also be staggered and will not overlap and entangle with each other, which is also helpful for the main traction wheel 2 to traction the photovoltaic welding tape to move.

[0034] Such as Figure 1 As shown, a rotating shaft is arranged on the lower side of the device body 1, and a guide wheel 7 is installed on the rotating shaft. The guide wheel 7 is rotatably connected to the rotating shaft. Finally, the photovoltaic welding tape passing through the main traction wheel 2 will vertically downward and pass through the guide wheel 7. After being turned by the guide wheel 7, it will pass out from the side of the device body 1.

[0035] Reference Figure 3 , in order to limit the up and down movement position of the main traction wheel 2, an upper limit switch 12 and a lower limit switch 13 are respectively arranged on the upper and lower sides of the lifting module 8. The limit switch is composed of a photoelectric sensor and a light blocking piece. The photoelectric sensor is fixedly installed on the lifting module 8, and the light blocking piece is fixedly installed on the sliding seat 11. When the sliding seat 11 moves up and down, the light blocking piece will successively pass through the upper and lower two photoelectric sensors, so as to detect whether the main traction wheel 2 reaches the specified position.

[0036] Such as Figures 5-8 As shown, the air duct plate 6 is installed inside the device body 1, and the main traction wheel 2, the guide wheel 4 and the reversing wheel 3 are all located in front of the air duct plate 6. A plurality of air nozzles 14 are installed on the air duct plate 6, and the photovoltaic welding tape can be blown through the air nozzles 14 to cool the photovoltaic welding tape.

[0037] The air duct plate 6 is a square frame structure formed by combining a first air duct plate 61, a second air duct plate 62, and a third air duct plate 63. The upper and lower ends of the first air duct plate 61 and the second air duct plate 62 are both connected by the third air duct plate 63. There is a channel inside the first air duct plate 61, the second air duct plate 62, and the two third air duct plates 63, jointly forming an annular air duct. At the same time, there are a number of air outlets 601 on the front side of the first air duct plate 61 and the second air duct plate 62. The number of air outlets 601 is arranged at equal intervals from top to bottom. A nozzle 14 is installed on each air outlet 601. The cooling air in the air duct is ejected through the nozzle 14 to cool the photovoltaic welding tape.

[0038] A wind inlet plate 64 is welded to one side of the first air duct plate 61. The inner side of the wind inlet plate 64 also has an air duct, which is an air inlet channel. The air inlet channel is connected to the air duct. At the same time, there is an air inlet 641 on the wind inlet plate 64. The air inlet 641 is connected to an external air source. The cold area air will enter the air duct through the air inlet channel and then be ejected through the nozzle 14.

[0039] The first air duct plate 61 and the second air duct plate 62 are respectively located on the left and right sides of the main traction wheel 2, and the distance between the first air duct plate 61 and the second air duct plate 62 is approximately the same as the diameter of the main traction wheel 2. Therefore, the cooling air ejected from the nozzles 14 on the first air duct plate 61 and the second air duct plate 62 just faces the photovoltaic welding tape to quickly cool the photovoltaic welding tape.

[0040] The above technical solution only reflects the preferred technical solution of the technical solution of the present utility model. Some changes that may be made to some parts by those skilled in the art of the present technology all reflect the principle of the present utility model and fall within the protection scope of the present utility model.
