6results about How to "Does not affect flatness" patented technology

The invention discloses a flat functional current collector and a preparation method thereof, and relates to the technical field of current collectors. The method specifically comprises the following steps that S1, an organic film and a metal foil are attached to the same release film, and interfaces in the thickness direction are in contact; an intermediate product A is obtained; s2, a metal layer is deposited on the face, away from the release film, of the intermediate product A, and an intermediate product B is obtained; and S3, removing the release film in the intermediate product B, and depositing a metal layer on the surface again to obtain the functional current collector. A continuous conducting layer can exist in the edge area of the functional current collector prepared by the method, and a tab is not required to be reserved or welded like a traditional current collector, so that the structural smoothness of the current collector is kept.

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.

The utility model relates to a television cabinet technical field especially disclose a television cabinet structure with adjustable baffle, including cabinet, cabinet includes first board body and second board body, and the length direction of first board body and second board body is crossed, is provided with adjusting assembly and first limiting assembly respectively on first board body and second board body, and adjusting assembly includes the first stop piece of relative first board body sliding setting, and first limiting assembly includes first strip piece and the first groove body of opening in first strip piece, and the crossed setting of first board body and second board body length direction plays the role of constructing television cabinet main body frame basic structure, makes television cabinet have the effect that basic space contains function, the first stop piece relative first board body sliding setting plays the role of flexible adjustment baffle position in adjusting assembly, realizes the user can according to actual demand, freely changes the position of first board body, improves television cabinet internal space utilization, satisfies the effect that the demand of diversified storage.

The invention relates to a post-tensioning method bonded prestress leveling layer structure and a construction method thereof, the post-tensioning method bonded prestress leveling layer structure comprises a leveling layer, steel strands and corrugated pipes, the thickness of the leveling layer is 5-8 cm, the corrugated pipes are arranged in the leveling layer in a criss-cross mode to form a net shape, the steel strands are arranged in the corrugated pipes in a penetrating mode, the outer diameter of the corrugated pipes is 14-20 mm, and the diameter of the steel strands is 6-12 mm; and a micro-resistance layer is arranged between the leveling layer and the structural layer. According to the post-tensioned bonded prestress leveling layer structure provided by the invention, the post-tensioned bonded prestress is applied to the leveling layer, so that large-area seamless construction of the prestressed leveling layer can be realized. And by means of a prestress system, the concrete slab is always in a pressed state, the cracking problem caused by temperature change or load action is effectively avoided, and the integrity and durability of the leveling layer are enhanced.

This invention relates to a hardening coating for PET pre-coated films, its preparation method, and a coating film. It includes a primer coating and a topcoat coating; the primer coating is composed of epoxy-modified acrylate, polyurethane-modified acrylate, a photoinitiator, a cationic initiator, a leveling agent, and an organic solvent; the topcoat coating is composed of polyurethane-modified acrylate, a photoinitiator, an organofluorosilicone additive, a reactive diluent, fillers, and an organic solvent. The primer coating uses an epoxy-modified acrylate compounded with a polyurethane-modified acrylate, combined with a dual-initiation system of a free radical photoinitiator and a cationic initiator; the topcoat coating uses polyurethane-modified acrylate as the main component, combined with organofluorosilicone additives and functional fillers, achieving simultaneous improvement in coating hardness, hydrophobicity, and abrasion resistance.

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.
