Description

Technical Field

[0001] The utility model relates to the technical field of panel splicing, and particularly relates to a panel vacuum closing device. Background Art

[0002] With the development of the information society, the requirements for display devices are increasing in various forms. Correspondingly, various flat panel display devices such as smart phones, LCD (Liquid Crystal Display Device), plasma display panel (PDP), ELD (ElectroLuminescent Display), and VFD (Vacuum Fluorescent Display) have been developed.

[0003] In addition, due to the popularization of smart phones and tablet computers, the demand for touch display screens has increased sharply. Generally, a touch display panel (also known as a touch panel) is manufactured by laminating a panel with additional touch functions on a common display panel such as an LCD.

[0004] When splicing display panels, PVB films (with a thickness of more than 200 microns) are used to achieve splicing through high-temperature heat treatment. In this traditional technology, the thickness of two panels is relatively thick, and high-temperature heat treatment is required, so the cost is relatively high. In addition, during the splicing process, even if the two panels are closely attached, there will be microbubbles. Over time, these bubbles will form an air layer, causing problems such as poor appearance and image distortion. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a panel vacuum closing device, which not only minimizes the connection thickness when connecting display panels and other panels, but also simplifies the connection process, and at the same time prevents the generation of microbubbles between the connection surfaces.

[0027] At least four groups of up-and-down driving units 40 are provided. Each group of up-and-down driving units 40 includes a support rod 41 and an up-and-down driving component 42. The up-and-down driving component 42 is fixedly installed on the auxiliary plate 13. The bottom of the support rod 41 is connected to the up-and-down driving component 42. The base plate 11 and the lower chamber body 21 are provided with shaft through holes 23 directly above the support rod 41. The upper chamber body 31 is provided with a shaft coupling part 33 directly above the support rod 41. The top of the support rod 41 slidably penetrates the shaft through hole 23 and is coupled with the shaft coupling part 33. The up-and-down driving component 42 is a cylinder, thereby realizing the up-and-down movement of the upper chamber body 31.

[0028] Each group of lower panel supporting units 50 includes a lower panel bracket 51 and a lower alignment unit 52. The lower panel bracket 51 is arranged in the lower chamber body 21, and the lower alignment unit 52 is arranged below the lower panel bracket 51. The lower panel brackets 51 are all connected with an external vacuum adsorption device. Through the external vacuum adsorption device, the lower panel brackets 51 can firmly adsorb the panel.

[0029] The upper panel support unit 60 includes an upper panel bracket 61, a support drive unit 62 and an upper alignment unit 63. The upper panel bracket 61 is movably arranged in the upper chamber body 31 through the support drive unit 62. The upper alignment unit 63 is arranged above the upper panel bracket 61.

[0032] The panel is a display panel, a glass panel, an iron panel or a wooden panel.

[0033] The working process of the utility model is as follows: first, the upper and lower driving units 40 work to move the upper chamber 30 upward, and the upper panel is vacuum-adsorbed to the upper panel support unit 60 located inside the upper chamber 30, and an optically transparent adhesive film is coated on the lower side of the upper panel.

[0034] The bottom of the lower panel is adsorbed to the lower panel support unit 50 located inside the lower chamber 20, and the upper panel attached to the upper panel support unit 60 and the lower panel attached to the lower panel support unit 50 are respectively aligned to the set position through the visual camera, and the upper and lower driving units 40 work to move the upper chamber 30 downward so that it is close to the lower chamber 20. Since the upper chamber 30 is close to the lower chamber 20, the upper space 32 and the lower space 22 of the upper chamber 30 and the lower chamber 20 are closed. Then, a vacuum is generated in the vacuum supply unit 70 and the vacuum is supplied to the lower chamber 20. The internal closed space formed by the upper chamber 30 and the lower chamber 20 forms a vacuum state, and the upper panel and the lower panel are driven by the support driving unit 62. The vacuum state of the sealed space is maintained for a set time, so that the microbubbles between the upper panel and the lower panel are fully connected by the adhesive film, and then the vacuum supply is stopped on the vacuum supply unit 70 to release the vacuum state. Next, the upper panel support unit 60 is separated from the upper panel, and the upper and lower driving units 40 are operated to move the upper chamber 30 upward, and then the upper and lower panels placed in the lower panel support unit 50 are taken out and closed. When repeating the above operation, the upper and lower panels are closed.

[0035] In the present utility model, an optically transparent adhesive is coated between two panels of a display panel, and the two panels are joined together while maintaining a vacuum state. At this time, the thickness of the adhesive film between the two panels becomes thinner, avoiding the formation of microbubbles between the two adhesive surfaces, thereby avoiding the problems of poor appearance and image distortion of the two joined panels, making the two panels more firmly joined, and the overall thickness becomes thinner.

[0036] The present utility model simultaneously performs the process of joining two panels constituting a display panel and the process of removing bubbles. Not only is the process simple, but the equipment composition is also simpler, improving work efficiency and reducing the manufacturing cost.

[0037] The present utility model can not only join the panels constituting a display panel, but also join panels such as glass plates, metal plates, and wooden plates together, improving the utilization rate.

[0038] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent replacements to the present utility model within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the technical solution of the present utility model.
