Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-thin flexible glass. Specifically, the utility model relates to a dispensing and alignment device for an ultra-thin flexible glass cover plate. Background Art

[0002] With the replacement of electronic products, glass has been widely used in the electronics industry. The market has increasingly higher requirements for the thickness of touch screen glass cover plates and protective glass. The ultra-thinning of glass has become one of the important development trends of glass. Ultra-thin glass cover plates have received more and more attention from listed companies in the electronic display industry, and are mainly applied to folding mobile phones, folding laptop computers and various wearable electronic devices. Ultra-Thin Glass (UTG) refers to glass with a thickness less than 100 μm and flexibility. Due to its advantages such as high transparency, stability and impact resistance, UTG is widely used in various electronic industries. Its bendable property has marked a major milestone in the folding display screen industry and has become an important position in the field of foldable flexible cover plates after CPI cover plates. The demand in the electronic display industry is increasing, and the product quality and production efficiency are getting higher and higher. Conventional ultra-thin flexible glass products can no longer meet the market demand. At present, ultra-thin flexible glass with a pattern in the bending area has more and more advantages in the ultra-thin glass manufacturing industry. However, during the dispensing process of ultra-thin flexible glass with a pattern, the glass needs to be neatly stacked on the platform, and manual placement is very likely to cause deviation, resulting in misalignment of the glass and affecting the product yield. Manual placement by the naked eye is unstable, which will cause the center line of the pattern to deviate from the center line of the overall shape, and then lead to abnormalities in the shape of ultra-thin flexible glass products in the form of patterns, and will also have an irreversible impact on the overall bending performance during the subsequent module installation.

[0003] In summary, the prior art has the following disadvantages:

[0004] 1. When dispensing the ultra-thin flexible glass cover plate of the pattern type, pure manual edge alignment is relied on, and the alignment accuracy is extremely poor, and the production efficiency is low;

[0005] 2. When dispensing the ultra-thin flexible glass cover plate, the skin of the staff will come into contact with the glue, resulting in skin allergies of the staff. During the process of aligning the glass by the staff during dispensing, they will come into contact with the glue many times.

[0006] A Chinese patent with the application number 201420176068.0 discloses a glass plate laminating and aligning device, which includes a base, a support platform installed on the base for supporting the glass plate, a dispensing mechanism for dotting glue on the glass plate, a rolling mechanism for rolling and laminating the laminated glass plates, an aligning mechanism for aligning the glass plates, a pre-curing mechanism for semi-curing the glue, and a reciprocating driving mechanism for driving the support platform to move back and forth between the above-mentioned mechanisms; the rolling mechanism includes a roller shaft and a support frame. By using the glass plate laminating and aligning device, multiple glass plates are laminated on the support platform, coated with glue, then aligned, and then the glue is semi-cured, which can quickly laminate the glass plates, with high lamination efficiency, and the use of the aligning mechanism can ensure the accuracy of the lamination of the glass plates.

[0024] The following is a further detailed description of the specific embodiments of the present utility model by referring to the accompanying drawings and describing the embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0025] Figures 5a to 5d For the processing process of the conventional pattern type ultra-thin flexible glass under ideal conditions, as Figure 5a represents the large plate after the processing of the pattern type ultra-thin flexible glass is completed, Figure 5b It is shown that multiple large plates after the processing of patterns are fixed in a stack of multiple through a specific reagent. Since there is currently no specific automated equipment, the process of stacking the large plates is usually carried out manually. In the ideal state, the stacked form is as Figure 5c shown, and each large plate is in a completely overlapping state, Figure 5c The horizontal and vertical lines in represent the laser cutting paths. The large plate is cut into small pieces of equal size through laser cutting, as Figure 5d shown. If the large plates are completely flush after stacking, the pattern area of the small pieces after laser cutting will be located in the middle. If the stacking state of the large plates is as Figure 6c shown, the large plates are not completely overlapping with each other and are inclined to a certain extent, which will cause different degrees of offset in the groove areas of the small pieces after cutting, and then affect the bending performance. Therefore, the present utility model provides a new type of dispensing and alignment device.

[0026] As shown Figures 1 to 4 in the figure, the present utility model provides a dispensing alignment device for an ultra-thin flexible glass cover plate, which includes a dispensing platform 1 and a positioning mechanism arranged on the dispensing platform 1 and used for positioning the glass cover plate, and positioning holes are arranged on the glass cover plate.

[0027] Specifically, as Figures 1 to 3 shown in the figure, the positioning mechanism includes positioning posts 2, and two positioning posts 2 are provided. The dispensing platform 1 is horizontally arranged, and guide holes for the positioning posts 2 to pass through are arranged on the dispensing platform 1. The two positioning posts 2 are arranged oppositely, and the two positioning posts 2 are on the same straight line parallel to the width direction of the dispensing platform 1. The two positioning posts 2 are respectively inserted into the two positioning holes of the glass cover plate placed on the dispensing platform 1 to position the glass cover plate.

[0028] Before dispensing, the glass cover plate needs to be processed. First, the large plate glass cover plate that needs pattern processing is laser cut on both sides parallel to the pattern area on the glass cover plate. The depth of the laser cutting is (the thickness of the large plate - the target thickness of the pattern ultra-thin flexible glass (usually < 30 μm)). The glass cover plate after laser cutting is thinned as a whole. The laser cut edges will be passivated by the continuous thinning of the acid solution at the laser cut. In this way, the glass cover plate will not break during the subsequent processing due to the opening, and during the thinning process, the shape of the laser cut area will be directly acid cut. After acid cutting, the large plate is as Figure 3 shown in the figure. There are two acid-cut ring openings on both sides of the pattern area on the glass cover plate, forming two positioning holes, and the two positioning holes are respectively located on both sides of the pattern area on the glass cover plate.

[0029] Preferably, the positioning posts 2 can be lifted and lowered in the vertical direction. The positioning posts 2 can position multiple glass cover plates at the same time, and the positioning posts 2 are connected to the lifting mechanism.

[0030] When the staff stacks the glass cover plates on the dispensing platform 1, the positioning holes of the glass cover plates are fitted with the positioning posts 2 on the dispensing platform 1, and the positioning posts 2 are inserted into the positioning holes. During the dispensing and rolling process, the lifting can be controlled. In this way, it can be ensured that during the process of multi-point dispensing of a stack of glass cover plates, each glass cover plate can be completely overlapped and fixed by the positioning posts 2, and the glass cover plates will not move, so that each glass cover plate is in a completely fitted state and no rolling fragments will be caused, perfectly solving the problem of offset during the dispensing process of the glass cover plates.

[0031] As Figure 4As shown in the figure, in this embodiment, the lifting mechanism includes a driving motor 4 and a transmission mechanism connected to the driving motor 4. The transmission mechanism is connected to the positioning column 2. The transmission mechanism is a lead screw nut mechanism. The driving motor 4 is fixedly installed below the dispensing platform 1. The output end of the driving motor 4 is fixedly connected to the lead screw of the transmission mechanism. The nut of the transmission mechanism is fixedly connected to the connecting member 3. The lead screw and the nut form a screw drive. The connecting member 3 is fixedly connected to the positioning column 2. A guide rod for guiding the connecting member 3 is provided on the dispensing platform 1. A guide hole for the guide rod to pass through is provided on the connecting member 3. The length direction of the guide rod is parallel to the length direction of the positioning column 2.

[0032] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantial improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, all are within the protection scope of the present invention.
