Embodiment 1

[0052] This embodiment provides a dispensing roller, such as figure 1 As shown, a roller body 1 is included, and an annular protrusion 2 protrudes from the outer wall surface of the roller body 1 .

[0053] Such as figure 2 As shown, the annular protrusion 2 includes a first end close to the roller body 1 and a second end far away from the roller body 1 , that is, the first end is opposite to the second end. in, image 3 show figure 2 In the enlarged view of part A, the axial width d2 of the first end face is greater than the axial width d1 of the second end face.

[0054] Please refer to figure 2 , the sidewall surface of the annular protrusion 2 in its radial direction is a first inclined surface 21, and the first inclined surface 21 is inclined outward from the second end toward the first end; The other side wall surface in the direction is a second inclined surface 22, which is inclined outward from the second end toward the first end.

[0055] The inclination ang...

Embodiment 2

[0062] This embodiment provides a dispensing device, such as Figure 4 As shown, it includes the dispensing roller, the glue supply mechanism 4, the support mechanism 3 and the recovery device in Embodiment 1. For the relevant structural details of the dispensing roller in this embodiment, please refer to Embodiment 1, which will not be repeated here.

[0063] The glue supply mechanism 4 includes a housing 41 and a driving member (not shown in the figure). Wherein, the housing 41 has a cavity for containing glue, and a glue outlet (not shown in the figure) opened on the side wall facing the radially outer surface of the annular protrusion 2 on the outer peripheral wall of the roller. Preferably, the colloid stored in the cavity is a low-precision colloid. Since the low-precision colloid has better adhesion and low cost, the cost of dispensing can be saved.

[0064] Such as Figure 5 As shown, there is an installation step 42 on the outer wall of the housing 41 , and a scrap...

Embodiment 3

[0078] This embodiment provides a dispensing system, such as Figure 6 As shown, the dispensing device and the rotating platform in Embodiment 2 are included.

[0079] Such as Figure 7 As shown, the dispensing system is installed on the installation platform, which is composed of upper and lower parts of the box. The electrical control system of the dispensing device is packaged inside the upper box body 71 , the dispensing device is installed on the outer surface of the upper box body 71 , and the rotating platform is used to realize dispensing of the screen body 62 . The lower box body 72 is used as a reserved space to lay the foundation for later transformation. For the details of the relevant components of the dispensing device in this embodiment, please refer to Embodiment 2, which will not be repeated here.

[0080] Such as Figure 6 As shown, the rotating platform in this embodiment is used to drive the screen body 62 to rotate, thereby indirectly driving the dispe...

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...
