[0027] Figure 3 Fig. 3 shows a top view of the handle assembly of the silk screen printing jig for ultra-thin glass according to an embodiment of the present application; Figure 4 Fig. 4 shows a top view of the base of the silk screen printing jig for ultra-thin glass according to an embodiment of the present application. As shown in Fig. 4, the base 200 comprises a handle assembly installation groove 210, a template fixing groove 220 and a fixing block installation groove 230. Figure 3 Figure 4 ​​As shown, the handle assembly 100 includes a silk screen part 110 and a hand-held part 120, which are integrally formed, the handle assembly mounting groove 210 includes a silk screen groove 2101 and a hand-held groove 2102, the silk screen part 110 is mounted in the silk screen groove 2101, and the hand-held part 120 is mounted in the hand-held groove 2102. In the embodiment, the silk screen part and the hand-held part are integrally formed, the number of connecting points is reduced, the overall structural strength is enhanced, and the handle assembly is not prone to loosening during operation. Meanwhile, the integrated design provides a better hand feeling, and the operator can move the glass more stably and comfortably. When polishing, the handle assembly is locked and connected with the base 200 through screws, so that the handle assembly is not accidentally loosened during polishing. After polishing, the locking connection between the handle assembly and the base 200 is released. After silk printing, the hand-held part can easily transfer the glass to the tunnel furnace, so that the ink is quickly solidified, the production efficiency is improved, the design effectively solves the problems that the ultra-thin glass cannot be slotted and fed in and out during processing, simplifies the operation process, and reduces the complexity of the process.

[0028] Figure 5 As shown in the side view of the base of the silk printing jig for ultra-thin glass provided by the embodiment of the utility model. Figure 4 And Figure 5 As shown, the base 200 is further provided with a base air hole area 240 surrounding the silk screen groove 2101 on the upper surface, the depth of the base air hole area 240 is equal to the depth of the silk screen groove 2101, a plurality of second through holes 2401 penetrating the base air hole area 240 are formed in the base air hole area 240, and a plurality of first through holes 1101 penetrating the silk screen part 110 are formed in the silk screen part 110. By forming the plurality of second through holes in the base and the plurality of first through holes in the silk screen part of the handle assembly, the number of air suction holes is greatly increased. This design can provide more uniform and stronger air suction effect, and reduce the silk printing defects caused by insufficient suction force. The plurality of first through holes in the silk screen part and the second through holes in the base are combined to form a more efficient air suction system, so that the vacuum suction force is always sufficient during printing, and the screen sticking phenomenon caused by insufficient suction force is avoided. By increasing the number of air suction holes and improving the air suction efficiency, the printing defects caused by bubbles and uneven air flow can be effectively reduced, the silk printing quality is higher, and the product qualification rate is improved.

[0029] Further, in an embodiment of the present application, the diameter of the first through hole 1101 and the diameter of the second through hole 2401 are less than 0.3mm. In this embodiment, the ultra-small air suction aperture can effectively avoid applying excessive pressure to the glass during air suction, thereby reducing the risk of glass deformation. Although the diameter of the individual hole is small, the arrangement of a large number of holes enhances the overall air suction effect, and the multiple small holes can uniformly distribute the suction force, ensuring that the glass is stable during the silk-screening process. Since the glass is not easily deformed, the printing defects caused by deformation, such as blurring or misalignment, are reduced, and the clarity and accuracy of the silk-screening are improved. This embodiment uses an air suction aperture of less than 0.3mm to ensure the air suction effect while effectively preventing glass deformation during the printing process, significantly improving the quality and stability of the silk-screening.

At the same time, a connector 500 is installed on the side of the fixing base 310, and an external vacuum pipeline is connected through the connector 500. The fixing base 310 is tightly connected with the base 200 through screws, ensuring the firmness during use, and such design prevents the components from loosening during operation, thereby improving the stability of the entire device. The sum of the depth of the fixing block installation slot and the depth of the handle assembly installation slot is equal to the thickness of the base, so that the fixing block can be accurately embedded therein, and this design ensures that the fixing block can completely cover the base air hole area and the silk-screening slot, avoiding air leakage and improving the vacuum sealing performance of the system. Through reasonable layout and design, the air flow can be effectively controlled in a closed environment, ensuring that the internal gas can be uniformly extracted during the vacuum process, preventing air bubbles from being generated, reducing the defect rate, and ensuring the consistency and reliability of the final product.

The design of the mold assembly not only applies to single printing, but also optimizes the needs of mass production. The high-precision positioning mechanism ensures the consistent position of each glass during printing, thereby achieving standardization of the printed pattern and quality. This is particularly important for production lines that require high-quality output, helping to improve overall production efficiency and reduce waste.
