[0049] Please refer to Figures 1 to 9 The embodiment of the present application provides a hem welding device 2, which comprises a hemming device 1, a welding device 2 and a first driving device. The hemming device 1 comprises a first rack assembly 11 and a roller assembly 12, the roller assembly 12 comprises a pair of first roller wheels 121, a hemming gap 13 is formed between the pair of first roller wheels 121, and each first roller wheel 121 is rotatably connected with the first rack assembly 11. The welding device 2 is connected with the hemming device 1, and the welding device 2 comprises a second rack assembly 21 and a welding assembly 22 arranged on the second rack assembly 21, and the second rack assembly 21 is in butt joint with the first rack assembly 11. The first driving device is arranged on the first rack assembly 11 and drives the first roller wheel 121 to rotate relative to the first rack assembly 11, so that the roller wheel rolls the hemming to-be-hemmed part and drives the hemming device 1 and the welding device 2 to move relative to the to-be-hemmed part as a whole.

[0050] The first roller wheel 121 included in the roller assembly 12 can be a pair or more than two pairs. When there are more than two pairs, the first roller wheels 121 can be distributed along the first direction X, and the hemming gaps 13 between each pair can be arranged oppositely.

[0051] The second rack assembly 21 and the first rack assembly 11 can be fixedly connected or detachably connected. Optionally, the second rack assembly 21 and the first rack assembly 11 can be detachably connected.

[0052] The first driving device includes, but is not limited to, a driving motor.

[0053] In some embodiments, the roller assembly 12 can be arranged at the bottom of the first rack assembly 11, and the welding assembly 22 can be arranged at the bottom of the second rack assembly 21. In this way, the edge locking and edge sealing operations on the edge locking member can be facilitated.

[0054] In some embodiments, the roller assembly 12 can be detachably connected to the first rack assembly 11. The detachable connection can be achieved by fastening with fasteners such as bolts, or by partially inserting one into the other for clamping and fitting. In this way, the roller assembly 12 can be repaired and replaced when it is damaged, which can reduce costs.

[0055] In some embodiments, the welding assembly 22 can be detachably connected to the second rack assembly 21. In this way, the welding assembly 22 can be replaced, and different welding processes can be used for edge sealing operations on the edge locking member, thereby meeting different edge sealing requirements of the edge locking member.

The rotation of the first roller 121 relative to the first rack assembly 11 not only allows the edge locking operation on the edge locking member placed in the edge locking gap 13, but also drives the edge locking device 1 and the welding device 2 to move relative to the edge locking member under the action of the reverse force of the edge locking member. The welding device 2 is connected to the edge locking device 1, and the second rack assembly 21 is connected to the first rack assembly 11. During the movement of the edge locking device 1 relative to the edge locking member, the welding device 2 can be driven to move relative to the edge locking member. During the movement of the welding device 2 relative to the edge locking member, the welding assembly 22 on the welding device 2 performs welding on the edge locking member, which can realize automatic edge locking and edge sealing. Not only is the cost low, but also the work efficiency is high, and the edge locking and edge sealing quality is high.

The second roller 23 can also guide the welding device 2 when moving, and facilitate the hemming member to be placed in the welding gap 25.
