The present disclosure relates to display technology, and more particularly, to an ultraviolet curing device.
In the existing skills, a liquid crystal infusion technique is usually adopted in pouring liquid crystal molecules into cells for large-scale display panels. Such a technique is first to drop a liquid crystal material onto the surface of a lower glass substrate. A glue dispenser machine is then utilized to apply a frame sealing glue with ultraviolet irradiation. Next, the lower glass substrate is placed in a vacuum environment, and then is aligned with and attached to an upper glass substrate, and a curing operation is performed therebetween. In this way, packaging the cells of the display panels is accomplished.
Currently, curing the frame sealing glue is usually carried out using an ultraviolet curing device. An existing ultraviolet curing device is equipped with only one-way irradiation in performing a curing operation. That is, the ultraviolet rays generated by the existing ultraviolet curing device only can irradiate downward directly. This way leads to a bad curing effect for the edge of the display panel. This may cause overflow if the glue on the edge is not cured completely. As a result, the quality of the display panel is affected.
In addition, it also requires the ultraviolet curing device in attaching the display panel to a cover plate. This may cause same problems as described above. Especially in attaching a flexible display panel to the cover plate, the curing at a curved portion of the flexible display panel is affected by the angle a light source is aimed at, thereby causing the curing unevenly.
Therefore, there is a need to provide an ultraviolet curing device in order to solve the problems in the existing skills.

To make above content of the present invention more easily understood, it will be described in details by using preferred embodiments in conjunction with the appending drawings.
The technical schemes and other beneficial effects will be more apparent with reference to the detailed descriptions of the embodiments of the present invention below in accompanying with the drawings.
To further illustrate the technical schemes adopted in the present disclosure and their corresponding effects, preferred embodiments of the present disclosure will be described in detail with reference to the appending drawings. Obviously, the embodiments described herein are a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of the present disclosure.
In the ultraviolet curing device of the present disclosure, the ultraviolet rays 200 emitted from the curing module 20 are irradiated at specific angles and reach the to-be-cured display panel 30 at different positions. For example, in order to curing the to-be-cured display panel 30 from two sides thereof, the ultraviolet rays 200 can be irradiated at specific angles to reach the two sides of the to-be-cured display panel 30. In such a way, curing at the two sides of the to-be-cured display panel 30 is better carried out, thereby improving the quality of the display panel.
Further, the curing module 20 includes a first curing module 201 and a second curing module 202. The first curing module 201 and the second curing module 202 are disposed at the two sides of the to-be-cured display panel 30, respectively, and are disposed symmetrically such that the to-be-cured display panel 30 can be cured at the two sides thereof at the same time. For example, in curing the to-be-cured display panel 30, the ultraviolet rays 200 can be irradiated at a specific angle by controlling the first curing module 201 to cure the to-be-cured display panel 30 at one side thereof. It is noted that the specific angle can be selected as needed, and the present disclosure is not limited thereto. That is, the selection of the specific angle is intended to make one side of the edge of to-be-cured display panel 30 sufficiently cured. Meanwhile, the ultraviolet rays 200 can be irradiated at a specific angle by controlling the first curing module 202 to cure the to-be-cured display panel 30 at the other side thereof. Similarly, the specific angle can be selected as needed, and the present disclosure is not limited thereto. That is, the selection of the specific angle is intended to make the other side of the edge of to-be-cured display panel 30 sufficiently cured.
In addition, the curing module further includes a control module 203 connected to the first curing module 201 and the second curing module 202. The control module 203 is configured to control the first curing module 201 and the second curing module 202 to irradiate the ultraviolet rays 20 to the to-be-cured display panel 30 at specific angles. For example, in curing the to-be-cured display panel 30, the control module 203 outputs a first control signal to the first curing module 201 and outputs a second control signal to the second curing module 202. The first control signal makes the first curing module 201 move to a location near one edge side of the to-be-cured display panel 30 as well as makes the first curing module 201 cure the to-be-cured display panel 30 at one side thereof at a specific angle. The second control signal makes the second curing module 202 move to a location near the other edge side of the to-be-cured display panel 30 as well as makes the second curing module 202 cure the to-be-cured display panel 30 at the other side thereof at a specific angle.
Specifically, as shown in
Further, the light emitting assembly 210 includes a light box 2101, and a light source 2102 and a reflection plate 2103 disposed inside the light box 2101. The reflection plate 2103 is disposed above the light source 2102 and is configured to reflect the ultraviolet rays 200 emitted from the light source 2102 toward an inner side of the light box 210, to the to-be-cured display panel 300. Preferably, the reflection plate 2103 is made of a heat-resistant material in order not to be affected by the heat emanated from the light source 2102. The heat dispersing material may be implemented by metal.
In order to increase the curing efficiency of the ultraviolet curing device of the present disclosure, the sample stage 10 of the present preferred embodiment can be implemented by a conveyor belt for transmitting the to-be-cured display panel 30 along a horizontal direction. Specifically, the to-be-cured display panel 30 can be transmitted to a position right below the curing module by the conveyor belt when a curing process is performed using the ultraviolet curing device of the present disclosure. After the display panel is cured, the cured display panel is transmitted along with the conveyor belt and is transmitted to a back-end area. Then, a next to-be-cured display panel is transmitted to a position below the curing module. In such a way, the efficiency is further improved.
In addition, in order to prevent some regions of the to-be-cured display panel from being cured insufficiently, the curing module 20 can be configured to move along a specific path back and forth. For example, in curing the to-be-cured display panel 30 at one side thereof using the first curing module 201, the specific path can be set from one edge side to a middle portion of the to-be-cured display panel 30. By using the control module 203, the first curing module 201 can be controlled to move back and forth along such a specific path, such that the to-be-cured display panel 30 are uniformly cured everywhere, similarly, in curing the to-be-cured display panel 30 at the other side thereof using the second curing module 202, the specific path can be set from the other edge side to a middle portion of the to-be-cured display panel 30. By using the control module 203, the second curing module 202 can be controlled to move back and forth along such a specific path, such that the to-be-cured display panel 30 are uniformly cured everywhere.
In the ultraviolet curing device of the present disclosure, the curing module is disposed above the to-be-cured display panel and is configured to emit the ultraviolet rays and make the ultraviolet rays irradiate the to-be-cured display panel at a specific angle. The curing module includes a first curing module and a second curing module. The first curing module and the second curing module are disposed symmetrically. In such a way, the to-be-cured display panel can be cured at the two sides thereof at the same time. The curing efficiency is increased. Also, the ultraviolet rays irradiated at specific angles can reach the to-be-cured display panel at the two sides thereof. In such a way, curing at the two sides of the to-be-cured display panel 30 is better carried out, thereby improving the quality of the display panel.
Above all, while the preferred embodiments of the present invention have been illustrated and described in detail, various modifications and alterations can be made by persons skilled in this art. The embodiment of the present invention is therefore described in an illustrative but not restrictive sense. It is intended that the present invention should not be limited to the particular forms as illustrated, and that all modifications and alterations which maintain the spirit and realm of the present invention are within the scope as defined in the appended claims.
