Embodiment 1

[0035] Embodiment one: if Figures 1 to 3 As shown, it is only one of the embodiments of the present invention, a kind of output detection device of optical adhesive paint, comprising a paint tank 1 and a three-way valve 2, and the three connection ports of the three-way valve 2 are respectively connected with discharge Pipe 3, return pipe 4 and output pipe 5, the end of the discharge pipe 3 away from the three-way valve 2 communicates with the paint tank 1 through the discharge pump 31, and the return pipe 4 is far away from the three-way valve 2. One end of the through valve 2 communicates with the paint tank 1 through the feed back tube 41, a first valve 42 is arranged between the feed back pipe 4 and the three-way valve 2, and the feed back tube 41 is connected to the paint tank 1. A second valve 43 is provided between the tanks 1, a return detection part 44 is provided on the return pipe 4, a return display screen 445 is provided on the return detection part 44, and the o...

Embodiment 2

[0056] Embodiment two, still as Figures 1 to 3 As shown, it is only one of the embodiments of the present invention. On the basis of Embodiment 1, in the output detection device of the optical adhesive paint of the present invention, the first plate 411 is set at an inclination. Generally speaking, the first plate 411 The end of the plate 411 close to the return pipe 4 is inclined upward, so that when the paint passing through the return pipe 4 flows into the return barrel 41 , it can flow to the bottom of the first plate 411 .

[0057] Of course, the return cylinder 41 is preferably a regular polygonal straight cylinder or a cylinder. When the flow rate of the optical adhesive paint flowing into the return cylinder 41 is constant, the rising speed of the connecting rod 413 is also constant, and the first plate 411 is just filled. The range of the return barrel 41 and the cross section prevents the optical adhesive paint from flowing to the top of the first plate 411 .

Embodiment 3

[0060] Embodiment three, such as Figure 4 As shown, the present invention also provides a detection method of an output detection device of an optical glue coating in all the above-mentioned embodiments, comprising the following steps:

[0061] S1: Fix the paint tank and the three-way valve, and connect the discharge pipe, return pipe and output pipe to the three connection ports of the three-way valve;

[0062] S2: Close the third valve and the second valve, open the first valve and the discharge pump, so that the optical glue paint in the paint tank enters the return pipe through the discharge pipe and the three-way valve;

[0063] S3: Determine whether the display value of the return display screen at the return pipe remains unchanged and the reading value of the return scale scale becomes larger and the speed is stable; if so, the display value of the return display screen and the reading value of the return scale scale change Acquire the viscosity value of the optical g...

The device is simple in structure, convenient to use and capable of being effectively suitable for optical cement coating, property detection can be conducted on the optical cement coating in the state that the optical cement does not see light and oxygen, coating deterioration waste is avoided, the output quantity and stability of coating output can be detected at the same time, and functions are diversified.

Description

technical field [0001] The invention relates to the technical field of paint detection, in particular, the invention relates to an output detection device and method of optical glue paint. Background technique [0002] OCA (Optically Clear Adhesive) is a special adhesive used for bonding transparent optical components (such as touch screens, displays, optical lenses, etc.). Traditional OCA optical tape has the advantages of colorless and transparent, light transmittance above 90%, good bonding strength, small curing shrinkage, no yellowing, etc., especially non-corrosive to ITO glass and optical components. Now, for optical adhesives The application of coating on the surface of products is also becoming more and more extensive. [0003] However, optical adhesive coatings may be stored for a long time after production, and optical adhesive coatings may be deposited or oxidized, resulting in changes in their properties, usually reflected in changes in viscosity and concentrat...
