Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of low lamination efficiency, large investment in equipment, and not easy to form running water in the process of optically laminating transparent functional panels on the surface of the existing display screen. In order to solve the problems of automated production, a device and method for water-glue pouring and laminating of display panels that can be streamlined is invented to avoid defects such as lamination air bubbles, cleaning of overflowing glue, and re-curing of glue after lamination. , so that the water glue pouring and bonding of the display panel can be streamlined and continuous operation, adapting to the automation requirements of the whole machine production, shortening the production cycle and saving production costs, while improving production efficiency and economic benefits

Embodiment 1

[0046]A water glue pouring and laminating device capable of streamlining a display substrate, which includes: a plurality of panel laminating platforms 2 that can move with the assembly line. The panel laminating platform 2 can be rotated along a rotating shaft parallel to the bottom edge. Obliquely stand at a certain angle θ with the horizontal plane, such asfigure 2 , There is a set of fixing frames 15 on the side opposite to the bottom (such asimage 3 a), the transparent rubber tube 14 used to fix the glue inlet and the air outlet and the support limit glue gas inlet and outlet pipe 16; the above-mentioned assembly line that can be streamlined includes, but is not limited to the following station groups: laminating panel group production station Group A1, panel positioning oblique station group A2, water glue filling station group A3, water glue curing station group A4; next to the water glue filling station A3 of the above assembly line, there are two separate glue inlet pipes 1...

Embodiment 2

[0057]In the first embodiment, the control θ1=15 º, θ=85º, constitutes the second embodiment of the present invention

Embodiment 3

[0059]In the first embodiment, in order to better prevent and control the glue overflow, set the minimum glue control amount as Vmin=98% S×d (where S is the effective glue bonding area of ​​the panel, and d is the thickness of the glue layer Minimum), when the glue volume reaches or approaches the minimum amount Vmin, the laminating platform rotates to the horizontal state of θ=0º, and at the same time controls the glue speed, and finally adjusts the glue slightly until the transparent rubber tube 141 of the air outlet of the panel assembly, there is When the water glue 10 overflows, stop the glue filling. At this time, the laminating platform rotates to the level and stands still, such asimage 3 c; Pull out the glue injection needle to separate the transparent rubber tube from the glue inlet and outlet pipes, such asimage 3 d, so that the laminating platform 2 can continue to move freely along the pipeline, which constitutes the third embodiment of the present invention

Abstract

The invention discloses a display panel glue pouring and laminating device and method capable of achieving streamlined operation. The display panel glue pouring and laminating device is characterizedin that the device comprises a plurality of panel laminating platforms capable of moving along with an assembly line, the bottom edges of the panel laminating platforms can rotate along a parallel shaft to obliquely stand to form angles theta (theta is larger than or equal to 0 and smaller than 90) with the horizontal plane, and a set of glue pipe fixing frames are arranged on each platform; the assembly line capable of achieving streamlined operation comprises but is not limited to the following station sets of a laminated panel set manufacturing station set A1, a panel positioning inclined standing station set A2, a glue pouring station set A3 and a glue curing station set; and two movable glue pouring needles connected with a glue inlet pipeline and an air outlet pipeline correspondingly are arranged beside a glue pouring station A2 of the assembly line, and the other end of the glue inlet pipeline is connected with a glue pouring machine. The device has the advantages of being lowin equipment investment, simple to operate, economical and practical, and capable of effectively shortening the production period, saving the production cost and improving the production efficiency and economic benefits.

Description

Technical field[0001]The present invention relates to a display technology, in particular to a display panel manufacturing technology, in particular to a water-based glue potting and bonding device and method for a display panel that can be streamlined.Background technique[0002]In order to improve the environmental adaptability of existing displays, it is a common technical measure to optically attach transparent functional panels to the display surface. This kind of optical bonding includes: dry film bonding represented by optically transparent pressure-sensitive adhesive films, etc.; water glue bonding represented by glue coating methods such as pattern dispensing, screen printing, and slit-coating. Glue potting is a special water glue bonding method that is beginning to be applied to display panel bonding, especially large panel bonding that does not require special coating equipment.[0003]The patent application number "CN201811305561.7" is "a water-adhesive bonding process for t...
