Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0016] like figure 1 As shown, a thin film adsorption device includes an adsorption disk 1, which is installed on a rotating seat 2. The adsorption disk 1 is conical, and an air extraction pipeline 3 is installed in the adsorption disk 1. There is a hollow space inside the rotating seat 2. cavity, the air suction line 3 passes through the cavity and is connected to the negative pressure device 4, and the rotating seat 2 is driven by a drive motor 7.

[0017] The negative pressure device 4 in this embodiment adopts an air extractor, which is used to extract air to generate negative pressure, thereby absorbing the film, and adopts the air extractor to provide negative pressure, which is easy to install and use.

[0018] In this embodiment, there are several small holes on the adsorption disk 1, and a layer of flexible medium layer 5 is connected to th...

Abstract

The invention relates to the technical field of automatic attachment, in particular to a thin film absorption device. The thin film absorption device comprises an absorption disc, wherein the absorption disc is arranged on a rotation seat and is in a conical shape, an air exhaust pipeline is arranged in the absorption disc, a cavity is formed in the rotation seat, the air exhaust pipeline penetrates through the cavity and is connected with a negative pressure device, and the rotation seat is driven by a driving motor. The thin film absorption device is simple in structure and reasonable in design, a plurality of small holes are formed in the absorption disc, a flexible dielectric layer is connected with the absorption disc, and wear of the absorption disc to a surface of a thin film can beprevented by the flexible dielectric layer so as to improve the attachment quality; the hole diameters of the small holes are 2-3 millimeters, and the distance between adjacent small holes is 2-4 centimeters; and with the adoption of the structure, the absorption effect is better.

Description

technical field [0001] The invention relates to the technical field of automatic attachment, in particular to a film adsorption device. Background technique [0002] In the production of mobile phones, computers, tablets, etc., it is necessary to attach the PBA flexible soft board to the backlight module. Attached to the specified attachment position on the backlight module, it needs to be attached after positioning with a jig, the process is cumbersome, the attachment speed is slow, and it is difficult to meet the needs of automatic production of the group; and the attachment method of manual attachment is prone to deviation Or the phenomenon of dislocation will affect the yield rate of the product. Moreover, the adsorption effect of the film adsorption device of the feeding device in the existing attaching machine needs to be improved, which sometimes causes abrasion to the film and affects the attaching quality. Contents of the invention [0003] The object of the pre...
