Description

Technical Field

[0001] The utility model relates to the field of display screen packaging, in particular to a rigid AMOLED UV frame glue curing device. Background Art

[0002] AMOLED screens have developed rapidly in recent years, from being used only in high-end products to being used in low-end products such as watches and bracelets. At present, low-end and mid-end screens often use rigid AMOLED screens, which means they cannot be bent and have a relatively mature and stable manufacturing process.

[0003] The packaging process of rigid AMOLED is particularly critical in its production. UV light is used for curing during the packaging process, and UV light will have a negative impact on the optoelectronic performance and life of AMOLED devices, especially blue light. The fluorescent material has a greater impact, and a UV Mask is usually required to mask the parts that do not need to be irradiated. Traditional UV-Masks need to be produced according to product design and masks corresponding to the pictures need to be produced. Different products need to switch to different UV-Masks, which not only increases the production cost of UV-Masks, but also the time to replace the physical UV-Mask when switching. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a rigid AMOLED UV frame glue curing device, which produces patterns of different products by controlling the angle of a deflectable reflector, thereby eliminating UV-Mask, reducing UV-Mask costs, and the time required to switch different UV-Masks for different products, thereby improving production capacity.

[0005] The utility model is achieved in this way:

[0006] A rigid AMOLED UV frame glue curing device comprises a light source, a controllable deflection reflector assembly sequentially arranged along the direction of light emitted by the light source, and a platform for supporting a substrate and through which UV light can penetrate.

[0007] Furthermore, the platform is a quartz platform.

[0008] Furthermore, the controllably deflectable reflector assembly includes a reflector with an adjustable deflection angle.

[0009] Specifically, the reflector is a galvos mirror.

[0010] Furthermore, the reflector is a reflector with adjustable moving direction.

[0011] Specifically, the reflecting mirror is movable in the X-axis direction and in the Y-axis direction.

[0012] Furthermore, the reflector assembly also includes an X-axis and a Y-axis servo motor mechanism for driving the reflector to move.

[0013] The advantages of the utility model are: the utility model generates a corresponding pattern to be cured by using a UV laser source and a deflectable reflector. By controlling the angle of the deflectable reflector, the effective area of ​​the product is prevented from being irradiated by UV light, thereby reducing the production cost of the UV-Mask and the time for replacing the physical UV-Mask when switching between different products, thereby improving the machine utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0015] Figure 1 It is a structural schematic diagram of the utility model.

[0016] The numbers in the figure are: UV laser source 1, platform 2, reflector 3, inner frame glue 100, outer frame glue 101, and product effective display area 102. DETAILED DESCRIPTION

[0017] In the description of the present invention, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] The technical solution of the utility model is as follows:

[0020] See also Figure 1 As shown, a rigid AMOLED UV frame glue curing device of the utility model comprises a UV laser source 1, a controllably deflectable reflector assembly sequentially arranged along the direction of light emitted by the light source, and a platform 2 for supporting a substrate and through which UV light can penetrate.

[0021] In a specific embodiment, UV light is generated by a UV laser source 1 , and the UV wavelength is usually 365 nm. The size of the point light source can be adjusted according to the product, and a 1.0 mm light source is usually used.

[0022] In a specific embodiment, the reflector assembly includes a deflectable and movable reflector 3, which can be a galvos mirror. By continuously controlling the angle of the reflector 3, a set of paths is generated so that the final landing point of the reflected light coincides with the UV glue to be cured. The path of a product pattern can be stored, and then when switching different products, the corresponding parameters can be selected without switching the physical Mask.

[0023] In a specific embodiment, the reflector assembly further includes a servo motor mechanism (not shown, conventional mechanism) for driving the reflector to move on the X-axis and the Y-axis. Since the distance from the UV point light source to the deflectable movable reflector is fixed, the distance from the reflector to the adhesive to be cured will change with the position. Therefore, the reflector needs to be designed to be movable, that is, movable on the x-axis and y-axis to form a two-dimensional plane, thereby ensuring that the distance from the UV point light source to the adhesive to be cured is the same at each position to be cured.

[0024] In actual production, the UV glue to be cured is divided into inner frame glue 100 and outer frame glue 101. This part is the area that needs to be irradiated with UV light. After being irradiated with UV light, it is cured to achieve the bonding of the base and cover, and to block external water and oxygen to prevent product failure. The effective display area of ​​the product 102 is prohibited from being irradiated with UV light. By controlling the deflection angle, the UV light path is avoided to avoid irradiating the effective area of ​​the product.

[0025] In a specific embodiment, the platform 2 is a quartz platform, which mainly supports the substrate and allows UV light to penetrate.

[0026] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
