This utility model relates to the technical field of screen protector application for mobile terminals such as mobile phones and tablets, specifically to a screen protector application auxiliary device, a screen protector applicator, and a screen protector application assembly. The screen protector application auxiliary device includes a positioning base with a receiving groove for holding the protective film. One side of the positioning base has an opening groove connecting to the receiving groove. Multiple pads are provided on the bottom wall of the receiving groove, each protruding from the bottom wall. The protrusion height of the pads farther from the opening groove is greater than that of the pads closer to the opening groove, so that the protective film is tilted after being placed in the receiving groove. The higher end of the protective film will first contact the screen of the electronic device, and the lower end will gradually adhere to the screen, allowing air to escape. Because the air is escaped in one direction, there is no risk of trapped air, effectively removing air bubbles and resulting in a good adhesion. Furthermore, due to the elevation effect of the pads, even if the bottom of the receiving groove deforms and bulges, it will not affect the flatness of the applied film.

This invention relates to the field of welding technology, specifically disclosing a welding device for manufacturing filing cabinets, applied to the welding of the joints between U-shaped panels and side panels. The device includes: a base; a traction unit; an outer positioning unit; an inner positioning unit; and a welding unit. The traction unit drives the welding unit to move at a uniform speed along the joint, avoiding welding interruptions caused by traditional clamps, eliminating multiple weld joints, preventing defects such as incomplete welding and lack of fusion, and ensuring that the entire joint is formed in one go with stable and reliable quality. The inner and outer positioning units move synchronously with the traction unit, keeping the side panels vertical throughout the process, preventing tilting or misalignment caused by thermal stress or external forces, and ensuring a constant relative position between the welding unit and the joint, providing a precise trajectory for continuous welding. The welding unit is placed on the inner positioning unit and welds from the inside of the cabinet, with the weld hidden inside. The outer surface is smooth and uniform, without any joint protrusions or depressions, meeting the dual requirements of aesthetic appearance and structural integrity for filing cabinets.
