Abstract

The utility model relates to a display panel film sticking deaerator which comprises a shell, a foam puncturing assembly, a foam squeezing assembly and a flattening assembly. The housing is provided with a containing cavity therein, and an opening is arranged at one end of the housing facing the display panel. The puncture assembly comprises a puncture needle arranged in the accommodating cavity, and the puncture needle is used for puncturing bubbles. The squeeze bulb assembly comprises two squeeze blocks which are arranged in the accommodating cavity at intervals, one of the squeeze blocks is movably arranged, and at least one of the squeeze blocks is provided with a notch. The flattening component comprises a roller arranged outside the shell, and the roller is used for rolling the bubble area. The film layer with bubbles can be continuously used after eliminating the bubbles, so that the material waste is avoided, and the manufacturing cost is reduced. Meanwhile, as the puncture needle cannot move towards the display panel, the film layer moves towards the puncture needle by utilizing the bulge of the film layer during extrusion, so that the puncture is realized, and the puncture needle is prevented from damaging other structures on the display panel.

Description

Display panel film sticking deaerator Technical Field The utility model relates to the technical field of manufacturing of display devices, in particular to a film sticking deaerator for a display panel. Background In the manufacturing process of the display panel, film layers such as a polarizing film and a protective film are required to be attached to the display panel so as to achieve the effects of improving visual effect, preventing water and the like. In the prior art, a film sticking machine is mainly used for sticking films to a display panel. Referring to fig. 1, the laminator includes two spaced rollers 3'. The display panel 1 'and the film sticking assembly 2' are laminated together, and pass through between the two rollers 3', and the two rollers 3' are used for pressing the display panel 1 'and the film sticking assembly 2'. The film-attaching member 2 'includes a carrier and a film layer 21' attached to the carrier. After the display panel 1' and the film pasting component 2' are pasted, the carrier in the film pasting component 2' is peeled off, and the film layer 21' is pasted on the display panel 1'. The air bubbles 22' are generated in the film layer 21' due to the influence of the bonding shape of the film layer 21', the influence of vibration of the roller 3', the influence of the levelness of the film-attaching unit 2', and the like. The air bubbles 22 'may affect the quality of the entire display panel 1'. For example, when the film layer 21' is a polarizing film, the presence of the air bubbles 22' affects the light emitting direction of a portion of the display panel 1', and affects the visual effect. When the film layer 21' is a protective film, the presence of the air bubbles 22' may affect the overall appearance of the display panel 1'. In the case of generating bubbles 22 'on the film layer 21', the conventional treatment method is to tear off the film layer 21 'with bubbles 22' and re-attach the film. This approach would result in wastage of the film 21' and correspondingly longer rework times. Or the operator pierces the air bubble 22' with a needle and then squeezes the vent and smoothes the repair area. The film layer 21' is easy to be stuck on the surface of the display panel 1' along with the needle point in the needling process, so that the film layer 21' is not easy to be punctured. And, the worker operates with great effort, and the needle tip damages other structures on the display panel 1'.
