Description

Technical Field

[0001] The utility model relates to the technical field of Mylar attachment, in particular to a Mylar fixture structure for attaching an F-edge back panel. Background Art

[0002] Mylar sheet (MYLAR sheet) PET polyester film is made of dimethyl terephthalate and ethylene glycol, which are heated with the assistance of relevant catalysts, and then subjected to ester exchange and vacuum polycondensation, and biaxial stretching. It has dimensional stability, flatness, excellent tear strength, heat resistance, cold resistance, moisture resistance, water resistance, chemical corrosion resistance, and super insulation performance, excellent electrical, mechanical, heat resistance, and chemical resistance. It can be used as insulating materials for motors, capacitors, coils, and cables. It can also be made into composite insulating materials with highland barley paper. It is now widely used in the electrical insulation industry and is suitable for gaskets, baffles, screens and protection for electronics, household appliances, instruments, displays, motor slots, computers and peripheral equipment. During the molding process of the TV frame, Mylar needs to be attached to the frame of the TV frame.

[0003] Existing Mylar attachment jigs usually have rollers that roll with the TV frame to achieve the Mylar attachment end abutting against the side of the TV frame. For example, Chinese patent announcement number CN216422244U discloses "a Mylar attachment jig" that is engaged with the outer edge of the TV frame through a set snap-in slot, so that the roller inside the snap-in slot rolls with the TV frame and achieves the Mylar attachment end abutting against the side of the TV frame, so that the Mylar attachment jig body slides along the TV frame.
