Problems solved by technology

However, in the case of the cover panel pasted on the liquid crystal template, since it is also an exterior decoration part of the final product, it is often printed except for the viewing window part, and ultraviolet rays cannot be transmitted. Therefore, it cannot harden temporarily

Embodiment Construction

[0033] Next, embodiments of the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the drawings.

[0034] [A. Structure]

[0035] [1. Overall structure]

[0036] First, the overall structure of the bonding apparatus of this embodiment (hereinafter referred to as the apparatus) will be described. This device is figure 1 As shown in , five holding devices 2 are mounted on the turntable 1 . The turntable 1 is configured to be intermittently rotated by an index mechanism in accordance with the insertion and removal position 1A, the adhesive material preparation position 1B, the positioning position 1C, the vacuum bonding position 1D, and the curing position 1E.

[0037] holding device 2 such as figure 2 As shown, it is a device that holds the workpiece S1 mounted on the placement unit 3 and the workpiece S2 held by the holding unit 4 facing each other up and down. In this embodiment, a liquid crystal template is used as t...

Abstract

Provided are a bonding apparatus and a bonding method wherein a positional shift of a work can be eliminated by a simple apparatus in a short time without deteriorating optical qualities and production efficiency. The bonding apparatus bonds a pair of works (S1, S2) with each other by having ultraviolet curable resin (T) therebetween, and the work (S2) is a cover panel provided with a view window section (W1) having a high visible light transmissivity, a blocking section (M) having a low visible light transmissivity, and a window section for curing (W2) which transmits ultraviolet rays (UV). The bonding apparatus has a pressing apparatus (5) which bonds the work (S2) to the work (S1) by pressing the work (S2), and partial irradiation apparatuses (54, 55) which apply ultraviolet rays (UV) to the window section for curing (W2) on the work bonded by the pressing apparatus (5).

Description

technical field [0001] The present invention relates to a bonding device and a bonding method which have improved the technology of bonding workpieces such as liquid crystal templates and cover panels. Background technique [0002] Generally, a liquid crystal panel is formed by laminating a liquid crystal template, a touch panel for operation, a cover panel (protective panel), and the like. These liquid crystal templates, touch panels, cover panels, etc. (hereinafter referred to as workpieces) are assembled on the frame of the liquid crystal template, and in order to avoid contact with the liquid crystal glass due to the deformation of the touch panel and cover panel, a space is formed between them. [0003] However, if a layer of air enters between the workpieces, the visibility of the display surface will decrease due to reflection of natural light. In order to cope with this situation, bonding is carried out by forming a layer that fills the space between the workpieces ...
