Description

Vacuum curing device

The present invention relates to a vacuum curing device, and more particularly to a vacuum curing device for curing a conforming panel.

In general, the panel bonding process is performed in a vacuum chamber. The adhesive material for the bonding panel may be a UV water glue or other colloid to be irradiated with UV light. When using UV water glue, if the bonding panel is not cured, the water gel is still liquid. When the bonding panel is taken, the upper and lower panels will slip and be misaligned, and the alignment accuracy of the bonding panel will run away. Therefore, the bonding panel should be UV cured first to adhere the upper and lower panels to avoid slippage.

At present, the UV curing treatment in a vacuum chamber is to open a quartz glass window on the vacuum chamber so that the UV light is transmitted through the quartz glass window to the bonding panel. However, the disadvantage of this method is that the distance between the UV light and the bonding panel cannot be close due to the window of the quartz glass. The intensity of the UV light is seriously attenuated due to the distance, so that complete UV curing or curing cannot be achieved. The time is lengthened.

Accordingly, it is an object of the present invention to provide a vacuum curing apparatus for curing a bonding panel to solve the above problems.

According to one embodiment, the vacuum curing apparatus of the present invention is used to cure a conforming panel. The vacuum curing device comprises a vacuum chamber and a combination of N light guides, wherein N is a positive integer. The conforming panel is placed in the vacuum chamber. Each of the light guide assemblies includes a support base, an adjustment member, and a light guide member. The support base is fixed in the vacuum chamber, the adjusting member is movably coupled to the support base, and the light guide member is disposed in the support base and the adjusting member. According to the size of the fitting panel, the adjusting member can be moved relative to the supporting seat to adjust the distance between the light guiding member and the bonding panel, so that the curing light emitted by the light guiding member is close to the bonding panel.

In summary, the present invention provides an adjustable light guide assembly in a vacuum chamber. Therefore, the operator can move the adjusting member relative to the supporting base according to the size of the fitting panel to adjust the distance between the light guiding member and the bonding panel, so that the curing light (for example, UV light) emitted by the light guiding member is close to the fitting panel. . Thereby, the vacuum curing device of the present invention can prevent the curing light from attenuating due to the distance being extended, and can also prevent the curing time from being elongated.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

1 and 2, FIG. 1 is a schematic view of a vacuum curing apparatus 1 according to an embodiment of the present invention, and FIG. 2 is an internal view of the vacuum curing apparatus 1 of FIG. As shown in Fig. 2, the vacuum curing device 1 of the present invention is used to cure a bonding panel 3, wherein the bonding panel 3 comprises a bonding material (for example, UV water glue or other colloid). Panel 30 and lower panel 32. As shown in Figures 1 and 2, the vacuum curing apparatus 1 includes a vacuum chamber 10, N light guide assemblies 12, and N gas leakage preventing members 14, wherein N is a positive integer. In this embodiment, the N system is equal to eight. However, in other embodiments, the number of light guide assemblies 12 and air leakage securing members 14 can be determined based on the actual application. In practical applications, the air leakage preventing member 14 can be a flange, but is not limited thereto.

The vacuum chamber 10 includes an upper chamber 100 and a lower chamber 102, and the upper chamber 100 is disposed on the lower chamber 102. The bonding panel 3 is placed in the vacuum chamber 10 composed of the upper cavity 100 and the lower cavity 102 for curing treatment. The N holes 104 correspond to the N light guide combinations 12 that are formed around the lower cavity 102 (in this embodiment, N is equal to eight). The air leakage preventing member 14 is locked to the lower cavity 102 and shields the corresponding hole 104 to prevent air from leaking into the vacuum chamber 10 from the hole 104.

Each of the light guide assemblies 12 includes a support base 120, an adjustment member 122, and a light guide member 124. The support base 120 is fixed in the vacuum chamber 10. The adjustment member 122 is movably coupled to the support base 120. The light guide 124 is disposed in the support base 120 and the adjusting member 122, and the light guide 124 is exposed to the vacuum chamber 10 via the corresponding leak-proof fixing member 14. In practical applications, the light guide 124 can be an optical fiber. The exposed light guide 124 is coupled to a curing light source (eg, a UV light source) to direct curing light into the vacuum chamber 10 to cure the conforming panel 3.

When the bonding panel 3 is cured, the operator first places the bonding panel 3 in the lower cavity 102, and according to the size of the bonding panel 3, the adjusting member 122 is moved relative to the supporting base 120 to adjust the light guide. The distance between the member 124 and the bonding panel 3 is such that the curing light (for example, UV light) emitted from the light guiding member 124 is in close proximity to the bonding panel 3. Thereafter, the upper cavity 100 is placed on the lower cavity 102 to start the curing process of the bonding panel 3. Thereby, the vacuum curing device of the present invention can prevent the curing light from attenuating due to the distance being extended, and can also prevent the curing time from being elongated.

Please refer to FIG. 2 and FIG. 3 together. FIG. 3 is a schematic view of the vacuum curing device 1 of FIG. 1 for curing another bonding panel 3'. As shown in FIG. 2 and FIG. 3, since the adjusting member 122 of the light guide assembly 12 is movable relative to the support base 120, the operator can move the adjusting member 122 relative to the support base 120 according to the size of the fitting panels 3, 3'. The distance between the light guiding member 124 and the bonding panel 3, 3' is adjusted, so that the curing light (for example, UV light) emitted from the light guiding member 124 is close to the bonding panel 3, 3'.

In contrast to the prior art, the present invention provides an adjustable combination of light guides in a vacuum chamber. Therefore, the operator can move the adjusting member relative to the supporting base according to the size of the fitting panel to adjust the distance between the light guiding member and the bonding panel, so that the curing light (for example, UV light) emitted by the light guiding member is close to the fitting panel. . Thereby, the vacuum curing device of the present invention can prevent the curing light from attenuating due to the distance being extended, and can also prevent the curing time from being elongated.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
