In the prior art, a rigid dispensing needle is generally used to dispense a gap between the bezel and the cover plate. However, with the trend of thinning display devices, the gap between the bezel and the cover plate is becoming smaller and smaller, and when the dispensing needle head is used to fill the glue in the small gap and the sectional area of the dispensing needle head is reduced to a certain extent, the dispensing needle head cannot discharge the glue due to the viscosity of the liquid optical glue, and the dispensing efficiency is greatly reduced by the dispensing needle head with a small sectional area. Therefore, in order to achieve both the filling of the glue in the small gap and the high glue dispensing efficiency, a further improvement of the glue dispensing device is still needed.

According to some embodiments of the present invention, the diameter of the glue dispensing heads 103, 303, and 403 may range from about 2 microns to about 20 microns, and the diameter of the fluid directing pin 102, D1, may range from about 2 microns to about 5 microns. In the embodiment of the present invention, the aperture of the flexible glue outlet sleeve head is larger than the aperture D1 of the fluid guide needle 102 to increase the glue passing area of the glue outlet (the definition of the glue passing area will be described in detail below), so as to increase the flow rate of the glue material, further improve the glue dispensing efficiency, and make the glue material with high viscosity also suitable for the glue dispensing process with small gap.
Referring to fig. 2, an enlarged view of a portion of an area 200 corresponding to the exemplary dispensing apparatus 100 of fig. 1 is shown according to some embodiments of the invention. As shown in fig. 2, according to some embodiments of the present invention, the dispensing device 100 includes a connecting portion 201 disposed between the nozzle body 102 and the dispensing sleeve head 103, a metal wire 202 wound around a joint of the connecting portion 201 and the dispensing sleeve head 103, and a sealant 203 coated on the joint.

In the embodiment of the invention, the metal wire 202 is wound around the joint of the second end of the connecting portion 201 and the glue dispensing sleeve head 103, so that the glue dispensing sleeve head 103 can be firmly jointed to the connecting portion 201. Moreover, the sealant 203 can be applied to the joint and the joint between the connection portion 201 and the fluid guide needle body 102 to prevent the leakage of the sealant in the dispensing process.
It should be noted that although the connecting portion 201, the metal wire 202 and the sealant 203 are only shown in fig. 2, the above components can also be applied to the dispensing devices 300 and 400 shown in fig. 3 and 4 to more firmly connect the glue-discharging sleeve heads 303 and 403 to the guide pin body 102.
Next, please refer to fig. 5. Fig. 5 is a top view illustrating a dispensing process performed on a display device 500 using the exemplary dispensing apparatus 100, according to some embodiments of the present invention. As shown in fig. 5, the sealant 502 formed on the display module 501 may have an opening OP for partially inserting the sealant head 103, so as to fill the sealant 502 with a liquid optical adhesive (LOCA) with high optical transmittance. In the embodiment of the invention, the length of the flow guide needle body 102 can be adjusted according to the product design, but the flow guide needle body 102 does not extend into the opening OP of the sealant, so the aperture D1 of the flow guide needle body 102 is not limited to be smaller than the thickness of the sealant. In the embodiment of the present invention, the flexible glue-discharging sleeve head 103 can fully fill the opening OP reserved by the frame glue 502, so as to prevent the injected liquid optical glue (LOCA) from leaking from the opening OP of the frame glue 502.
Please refer to fig. 5 with fig. 6. FIG. 6 is a cross-sectional view of a line A-A' of the display apparatus 500 of FIG. 5 according to some embodiments of the present invention. As shown in fig. 6, the display device 500 includes a display module 501, a metal frame 601 disposed on the display module 501 for shaping the display module 501, a cover 602 disposed on the metal frame 601, and a sealant 502 for adhering the metal frame 601 and the cover 602. The liquid optical adhesive (LOCA) injected through the adhesive discharge head 103 is filled between the display module 501 and the cover plate 602 and filled in the range surrounded by the sealant 502 to join the display module 501 and the cover plate 602.
In fig. 6, the sealant 602 has a first thickness T1. According to some embodiments of the present invention, when the thickness of the flexible film used to form the stripper head is in the range of about 40 to about 50 micrometers, it is suitable for products having a first thickness T1 of 0.2 millimeters (mm) or more. On the other hand, the aperture of the glue outlet sleeve head can be adjusted according to the product design and the matched glue dispensing manufacturing process, so that the glue passing area of the glue outlet is adjusted. Specifically, the flux area can be defined as:
Aperture D2 of the adhesive outlet sleeve head (sealant thickness T1-flexible film thickness x2)
In the embodiment of the invention, the glue passing area of the glue outlet can be increased by adjusting the aperture D2 of the flexible glue outlet sleeve head and the selected thickness, so that the flow of Liquid Optical Cement (LOCA) is improved, and the dispensing efficiency is further improved. Moreover, due to the increase of the glue passing area, the high-viscosity glue material can also be suitable for the glue dispensing manufacturing process with small gaps (i.e. the glue thickness T1). In other words, the selection range of the viscosity of the glue material can be expanded by increasing the glue passing area, for example, in the case of using a rigid needle, only a low viscosity (e.g., about 100 cps) glue material can be applied, and in the case of using the dispensing device provided by the embodiment of the present invention, a high viscosity (e.g., about 3000cps) glue material can also be applied.
In summary, the dispensing apparatus provided in the embodiments of the present invention provides the following advantages:
1. the problem of apron and the clearance undersize that sets up the metal frame on the display module to the work efficiency that the rigid needle head inserted and carries out the encapsulating is too low and influence the productivity is solved.
2. Because the flexible glue outlet sleeve head is used, the glue passing area of the glue outlet is changed, and the flow rate of the glue outlet is increased, so that the use of the glue outlet sleeve head in the embodiment of the invention is not limited to low-viscosity glue materials, and the glue outlet sleeve head with relatively high viscosity is also suitable for use.
3. The flexible glue outlet sleeve head can also avoid the scratch caused by the direct contact of the glue dispensing needle body and the product.
4. In the dispensing manufacturing process, the flexible dispensing sleeve head can fully fill the dispensing opening reserved by the frame glue, so that the injected glue material is prevented from leaking out of the opening of the frame glue.
5. The distance between the display module and the cover plate (namely the thickness of the filling rubber material) is reduced, so that the consumption of the rubber material is saved, and the manufacturing process cost is reduced.
The foregoing outlines several embodiments so that those skilled in the art may better understand the aspects of the present embodiments. Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other processes and structures for carrying out the same purposes and/or achieving the same advantages of the embodiments introduced herein. Those skilled in the art should also realize that such equivalent processes and structures do not depart from the spirit and scope of the present invention, and that they may make various changes, substitutions and alterations herein without departing from the spirit and scope of the present invention.
