[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Embodiment 1

[0020] As Figure 1 、 Figure 2 and Figure 3 shown, a welding device for a charging box housing with a combination of multiple products includes a lower die 1 and an upper die 6. Two handles 2 are symmetrically arranged on the lower die 1. The lower die 1 and the upper die 6 are connected by a lifting mechanism. One side of the upper die 6 close to the lower die 1 is fixedly connected with a fixed plate 8 through a connecting shaft 7. A plurality of riveting rods 15 are fixedly connected to the side of the fixed plate 8 away from the upper die 6. Each riveting rod 15 is fixedly connected with a plurality of welding heads 16. A retractable protection mechanism is installed on the fixed plate 8.

[0021] Specifically, the lifting mechanism includes a cylinder. The cylinder is fixed on the top of the lower die 1, and the output end is fixedly connected with the upper die 6. By driving the lifting of the upper die 6, it is controlled whether the welding head 16 approaches the lower die 1. At least three welding heads 16 are installed on one riveting rod 15. The specific arrangement shape and quantity can be arranged according to actual needs. The setting of multiple welding heads 16 ensures that all welding points can be welded synchronously, maintaining consistency, making the force on the charging box product 5 uniform, and improving the welding efficiency while improving the welding quality.

[0022] As Figure 1 shown, on one side of the lower mold 1 close to the upper mold 6, a detachable profiling support 3 is installed. The number of profiling supports 3 is at least two. A lower mold 4 is arranged in the middle of the multiple profiling supports 3. The side of the profiling support 3 away from the lower mold 1 is sprayed with PU glue, and a charging box product 5 is placed there.

[0023] Specifically, the profiling support 3 is installed on the lower mold 1 through bolts, and the profiling support 3 can be replaced according to different shapes of the charging box product 5. The PU glue sprayed on the outer surface of the profiling support 3 can increase the stability between the charging box product 5 and the profiling support 3, so that when the welding head 16 performs welding, the charging box product 5 will not be displaced.

[0024] As Figure 3 shown, a plurality of cold air pipes 17 are arranged in a circumferential array on the fixing plate 8. The multiple cold air pipes 17 are arranged around the welding head 16 and can quickly cool the welding point.

[0025] Embodiment 2

[0026] As Figure 1 、 Figure 2 and Figure 3 shown, a welding device for a charging box housing with multiple products combined. Compared with Embodiment 1, the protection mechanism of this embodiment includes a piston rod 9. The piston rod 9 is movably sleeved in the inner ring of the fixing plate 8, and anti-disengagement baffles 10 and hollow plates 11 are respectively fixedly connected to both ends of the piston rod 9. A buffer block 13 is fixedly connected to the side of the hollow plate 11 close to the lower mold 1, and a rubber pad 14 is bonded to the side of the buffer block 13 away from the hollow plate 11.

[0027] It should be noted that the anti-disengagement baffle 10 is threadedly connected to the piston rod 9. When the anti-disengagement baffle 10 is separated from the piston rod 9, the piston rod 9 can be pulled out from the inner ring of the fixing plate 8. At the same time, the diameter of the anti-disengagement baffle 10 is larger than the inner ring diameter of the fixing plate 8, so that when the anti-disengagement baffle 10 is installed on the piston rod 9, the piston rod 9 cannot be separated from the fixing plate 8. Compared with the welding head 16, the rubber pad 14 is closer to the lower mold 4.

[0028] As Figure 2 shown, an elastic member 12 is fixedly connected between the fixing plate 8 and the hollow plate 11. The elastic member 12 is a spring and is sleeved on the outer ring of the piston rod 9 for pushing the hollow plate 11 away from the fixing plate 8.

[0029] Specifically, when the lifting mechanism drives the upper mold 6 to descend, the rubber pad 14 first contacts the charging box product 5, providing a buffer area for the welding head 16 to prevent the welding head 16 from directly approaching the charging box product 5 and causing direct compression damage to itself and the charging box product 5.

[0030] Working principle: The lifting mechanism controls whether the welding head 16 approaches the lower die 1 by driving the lifting of the upper die 6. At least three welding heads 16 are installed on one riveting rod 15. The specific arrangement shape and quantity setting can be arranged according to actual requirements. The setting of multiple welding heads 16 ensures that all welding points can be welded synchronously, maintaining consistency, making the force on the charging box product 5 uniform, improving the welding quality while improving the welding efficiency. When the lifting mechanism drives the upper die 6 to descend, the rubber pad 14 first contacts the charging box product 5, providing a buffer area for the welding head 16 to prevent the welding head 16 from directly approaching the charging box product 5 and causing direct compression damage to itself and the charging box product 5. At the same time, the cold air pipe 17 can quickly cool the welding points.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
