Embodiment 1

[0027] Embodiment 1 of the present invention provides a frame sealant curing device, the curing device includes a sealed box, an ultraviolet light source 2 arranged in the sealed box, and an optical fiber 3 arranged in the sealed box and connected to the ultraviolet light source, such as figure 1 As shown, among them, figure 1 The sealed box is not indicated in the box.

[0028] Specifically, in the embodiment of the present invention, the optical fiber 3 is used to transmit the ultraviolet light emitted by the ultraviolet light source 2 to the position of the sealant 10 to be cured on the packaging substrate 1 placed in the sealed box. Expose at the position where the sealant 10 to be cured is arranged, and cure the sealant at the position.

[0029] Preferably, in the embodiment of the present invention, a switch component (not shown in the figure), such as a light valve, can be provided between the optical fiber 3 and the ultraviolet light source 2, and whether the light em...

Embodiment 2

[0036] Embodiment 2 of the present invention will describe the frame sealant curing device involved in Embodiment 1 in detail in combination with practical applications, but of course it is not limited thereto.

[0037] In the embodiment of the present invention, a transmission part 4 may be provided in the frame sealant curing device involved in the first embodiment, the optical fiber 3 is fixed on the transmission part 4, and the transmission part 4 drives the optical fiber to move on a plane parallel to the packaging substrate.

[0038] Further preferably, in the embodiment of the present invention, the transmission part 4 can be routed according to the position of the sealant to be cured on the packaging substrate 1, so that the trajectory 11 driven by the transmission part 4 to move the optical fiber 3 and the wiring of the sealant to be cured on the packaging substrate Consistent, and finally transmit the ultraviolet light emitted by the ultraviolet light source to the co...

Embodiment 3

[0043] Embodiment 3 of the present invention will describe the frame sealant curing device involved in Embodiment 1 in detail in combination with practical applications, and of course it is not limited thereto.

[0044] Embodiment 3 of the present invention In the frame sealant curing device involved in Embodiment 1, there are several optical fibers 3 connected to the ultraviolet light source 2 , and several optical fibers 3 are arranged on the top of the sealing box 5 .

[0045] Specifically, the arrangement of the optical fibers 3 arranged on the top of the sealed box in the embodiment of the present invention can be flexibly arranged, for example, several optical fibers 3 are evenly arranged on the top of the sealed box 5 at fixed intervals, such as Figure 5 shown.

[0046] Specifically, using Figure 5 In the arrangement shown, when it is necessary to cure the sealant to be cured on the packaging substrate 1, the optical fiber at the position corresponding to the positio...

Abstract

The invention discloses a sealing agent curing device, and aims to solve the problems that the product yield is reduced and the curing time is long when a curing device in the prior art is used for performing sealing agent curing. The seal material curing device comprises a seal box, an ultraviolet source arranged in the seal box and optical fibers arranged in the seal box and connected with the ultraviolet source, wherein ultraviolet light of the ultraviolet source is transmitted onto the position of a to-be cured sealing agent on a package substrate in the seal box, and is exposed in the position, so that the light emitted from the ultraviolet source cannot be scattered to other positions, and a mask plate is not required to be independently arranged for shielding.

Description

technical field [0001] The invention relates to the field of liquid crystal screen manufacturing, in particular to a frame sealing glue curing device. Background technique [0002] During the production process of the LCD screen, two substrates need to be packaged in a box. When the substrate is packaged in a box, it is generally necessary to use a sealing glue coating device to coat the sealing glue around one substrate; then vacuum lamination Two substrates, that is, the box alignment process; finally, the curing of the sealing glue. [0003] When the sealant is cured, the sealant is generally irradiated with ultraviolet light (UV, Ultraviolet Rays) for a short time to partially cure the sealant, and then placed in a UV-cured sealing box to further cure the photosensitive resin in the sealant. Finally, the uncured frame sealant is completely cured in a high-temperature furnace to complete the curing of the frame sealant. [0004] In the prior art, when ultraviolet light ...
