This invention discloses a welding device for the production of metal parts, relating to the field of metal parts processing technology. The invention includes: a main body with a slide rail on the top of its inner wall; an electric telescopic rod inside the slide rail; a welding mechanism fixedly installed at the bottom of the telescopic end of the electric telescopic rod; and two symmetrically mounted, rotatably rotating electric rotating rods on the inner sidewalls of the main body. The outer wall of each electric rotating rod has a non-self-locking spiral groove. This invention, through the use of simple mechanical structures such as a U-shaped telescopic frame and a U-shaped elastic clamp, can adaptively complete the positioning and flipping during the welding process according to the size of the parts, avoiding the limitation of welding only one side of the part in a single operation. This effectively improves the efficiency and comprehensiveness of part welding. Simultaneously, when the U-shaped telescopic frame resets, the U-shaped elastic clamp continuously contacts the part, preventing the weld from being insufficiently fixed and thus reducing the welding strength.

This application provides a laser welding machine applied in the field of motor equipment processing technology. The machine utilizes a machine base, with its top surface serving as the processing surface, where the stator is transported and processed. A stator cage assembly, located on the processing surface, includes a loading fixture and a loading machine. The loading machine has a cage, and the stator is fed onto the loading fixture, where the loading machine presses the cage onto the stator. A stator transport assembly is also located on the processing surface. This solution addresses current issues such as weld seam misalignment and insufficient thermal deformation control, which affect the stator's electromagnetic performance. Furthermore, current stator processing relies on manual or simple mechanical handling devices for material transfer. When facing multi-variety, small-batch production demands, these devices suffer from poor compatibility and low transport efficiency. Some robotic arm solutions lack real-time detection mechanisms, making them prone to assembly errors due to positioning deviations.

This invention discloses a stacking mechanism for wet wipe production. The invention relates to the field of wet wipe stacking and packaging, and includes a base plate. Two sets of support rods are fixedly connected to the top side wall of the base plate. The upper end of each set of support rods is fixedly connected to the same support plate. A conveying assembly for fixing and conveying the wet wipe box is rotatably connected to the inner walls of the two support plates. This invention automatically identifies the orientation of the wet wipe pack openings using a pressure sensor in conjunction with various adjusting components. It automatically corrects wet wipe packs with abnormal orientations, ensuring that all wet wipe packs have the same opening orientation within the wet wipe box. Then, a pusher plate compresses and shapes the stacked wet wipe packs, resulting in a tight and neat stack. Compared to existing technologies that rely on manual placement and simple, rough mechanical stacking, this invention features fully automated operation without human intervention. It achieves high consistency and regularity in stacking, effectively avoiding the problems of misalignment and messy stacking caused by manual placement.
