The invention discloses a uniform coating device for a hardened layer of a mobile phone touch screen. The uniform coating device comprises an integrated box and supporting bases. A coating material cavity and a hot air cavity are formed in the inner side of the integrated box, an exhaust fan is fixedly installed at the upper end of the hot air cavity, heating pipes are distributed at the lower endof the hot air cavity at equal intervals, and an air cylinder is fixedly installed at the lower end of the integrated box. A coating cavity is movably connected to the lower end of the air cylinder,a protective sleeve is fixedly connected to the upper end of the inner side of the coating cavity, a movable rod is movably connected to the lower end of the protective sleeve, a first spring is fixedly connected between the protective sleeve and the movable rod, and a flow limiting ball is movably connected to the lower end of the movable rod. A supporting frame is fixedly connected between the upper ends of the supporting bases, and the integrated box is fixedly installed at the upper end of the supporting frame. According to the uniform coating device for the hardened layer of the mobile phone touch screen, the air cylinder drives the coating cavity to move downwards to enable the flow limiting ball to be in contact with the touch screen, the gap between the coating cavity and the flowlimiting ball is adjusted by changing the opposite acting force, and the outflow speed of materials is controlled.
Description
technical field [0001] The invention relates to the technical field of screen processing equipment, in particular to a uniform coating device for a hardened layer of a mobile phone touch screen. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. According to the pre-programmed program to drive various connecting devices, it can be used to replace the mechanical button panel, and to produce vivid audio-visual effects through the liquid crystal display screen. As a new computer input device, the touch screen is simple, convenient and natural. A way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. Mainly used in public information query, industrial control, military command, electronic games, multimedia teaching, etc. [0003] PET film is often used as the substrat...
