Abstract

The invention discloses a glue coating idler wheel, a glue coating device and a glue coating system. The glue coating idler wheel comprises an idler wheel body and at least one annular protrusion molded on the circumferential outer wall surface of the idler wheel body in a protruded manner, at least one side wall surface in the radial direction of the at least one annular protrusion appears as a first inclined surface, and the axial direction width of a first end surface, close to the idler wheel body, of the at least one annular protrusion is larger than that of a second end surface, away from the idler wheel body, of the at least one annular protrusion to make the at least one first inclined surface incline outwards from a second end towards a first end; the glue coating device comprisesthe glue coating idler wheel, a glue supplying mechanism and a supporting mechanism; and the glue coating system comprises the glue coating device and a rotating platform. According to the glue coating idler wheel, the glue coating device and the glue coating system, because the at least one annular protrusion is molded on the circumferential outer wall surface of the idler wheel body in a protruded manner, the at least one side surface in the radial direction of the at least one annular protrusion appears as the first inclined surface, therefore, in the glue coating process, point contact isformed between a glue body to be coated and the at least one annular protrusion of the idler wheel, abnormal bumping of the glue body to be coated can be effectively prevented, and meanwhile, the problem of glue overflow is avoided.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a glue dispensing roller, a glue dispensing device and a glue dispensing system. Background technique

[0002] In current portable electronic devices, a touch panel is basically configured on a display panel such as a liquid crystal panel or an Organic Light Emitting Diode (OLED for short) panel. The touch panel is a light-transmitting input device, which is mainly composed of an electrode layer composed of a light-transmitting substrate and a transparent conductive film. The touch panel can visually recognize the image displayed by the display panel. Therefore, the operator can directly perform an input operation on the touch panel while viewing images and menu screens displayed on the display panel.

[0003] In an existing display screen with a touch function, a touch panel needs to be added to the original display panel. In the current panel technology, after the touch pane...
