Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, specifically to a positioning tool for thin film cutting. Background Technology

[0002] Thin film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, thin film is defined as a two-dimensional material formed by the deposition of atoms, molecules, or ions on a substrate surface. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in industries such as electronics, machinery, and printing. Tooling, or process equipment, refers to the general term for various tools used in the manufacturing process, including cutting tools, fixtures, molds, gauges, and workstation equipment. Tooling is its common abbreviation. Fixtures are process devices used during machining to quickly secure workpieces and maintain the correct relative positions of machine tools, cutting tools, and workpieces.

[0003] During film production, to meet different user needs, films need to be cut according to different applications. During film cutting, positioning fixtures are required to position the film and prevent it from shifting during cutting. A search reveals Chinese patent CN219633971U, which discloses a positioning fixture for film cutting, including a work plate with two symmetrically distributed grooves on its top surface. This utility model provides a positioning fixture for film cutting that, through the combined use of a threaded rod, nut, and limiting groove, facilitates the installation and removal of guide rods.

[0032] As a technical optimization of this utility model, the moving component 10 facilitates the movement of the clamping block 6 and the cutter 7, enabling the cutter 7 to cut the film.

[0039] The working principle and usage process of this utility model are as follows: When in use, the user places the film on top of the placement plate 2, and then starts the heating base 901. After the heating base 901 is started, the cutting tool 7 is heated through the heating tube 902. Then, the user starts the electric push rod 4. The output end of the electric push rod 4 drives the connecting block 5 and the pressure plate 8 to move downward, so that the pressure plate 8 presses and positions the film on top of the placement plate 2. At this time, the user starts the motor 101 and the fan 113. The output end of the motor 101 drives the disc 102 and the movable rod 103 to rotate clockwise. The rotation of the movable rod 103 drives the clamping block 6 and the heated cutting tool 7 to move downward, so that the heated cutting tool 7 cuts the film on top of the placement plate 2. At the same time, the input end of the fan 113 draws in the exhaust gas generated when cutting the film through the collection cover 111. The output end of the fan 113 delivers the exhaust gas to the left side of the pipe 112. When the exhaust gas passes through the pipe 112, it is filtered by the filter block 114 and the dust bag 115.

[0040] In summary, this positioning fixture for film cutting uses an electric push rod 4 to push the connecting block 5 and the pressure plate 8 to press and position the film on top of the placement plate 2. Then, the heating component 9 and the moving component 10 drive the cutter 7 to cut the film. Finally, the adsorption mechanism 11 treats the exhaust gas. This solution solves the problems that the positioning fixture cannot position the film during cutting, the film is prone to displacement during cutting, and burrs appear at the cut, affecting the quality of the film.
