Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean 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 an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0018] See also Figure 1-Figure 2 As shown, in this specific embodiment, a cover plate screen printing jig is disclosed, comprising a substrate 10, a positioning member 20, and a vacuum through-hole 40. The substrate 10 is used to support the cover plate to be processed. The positioning member 20 is placed on the surface of the substrate 10. The positioning member 20 forms a receiving groove 30, which is used to position and receive the cover plate to be processed. The vacuum through-hole 40 passes through the substrate 10 and is in communication with the receiving groove 30. A vacuum generator absorbs the cover plate to be processed located within the receiving groove 30 through the vacuum through-hole 40. The cover plate screen printing jig forms the receiving groove 30 with the positioning member 20 to cooperate with the substrate 10 to position and install the cover plate to be processed. Furthermore, the vacuum through-hole 40 is provided to absorb the cover plate to be processed, thereby achieving precise positioning of the cover plate to be processed and preventing the cover plate to be processed from rotating during the screen printing process. The cover plate screen printing jig has a simple overall structure and low cost, meeting the needs of the production line.

[0019] In one embodiment, a sinking platform 11 is further provided on the substrate 10. The sinking platform is in communication with the receiving groove 30 and is located in the middle of the receiving groove 30. Providing the sinking platform 11 on the substrate 10 and locating the sinking platform 11 in the middle of the receiving groove 30 can reduce the contact area between the substrate 10 and the cover plate to be processed, thereby reducing the risk of scratching the cover plate to be processed.

[0020] In one embodiment, the vacuum hole 40 is located in the middle of the sink 11. That is, the vacuum hole 40 is opened in the middle of the sink 11 to facilitate simultaneous processing of the vacuum hole 40 and the sink 11. At the same time, it ensures that the vacuum generator can exert suction force on the middle position of the cover plate to be processed, ensuring that the cover plate to be processed does not tilt during the screen printing process.

[0021] In one embodiment, the positioning member 20 is integrally formed on the surface of the substrate 10 , which facilitates the integral processing of the substrate 10 with the positioning member 20 , thereby reducing the processing difficulty and the cost of the jig.

[0022] In one embodiment, the positioning member 20 includes a plurality of positioning facets 50, which together form a receiving groove 30. The receiving groove 30 is defined by the plurality of positioning facets 50 of the positioning member 20, which can further ensure the placement position and angle of the cover plate to be processed, and further limit the processing of the cover plate.

[0023] In one embodiment, the positioning member 20 includes a first positioning member 21 and a second positioning member 22. The first positioning member 21 and the second positioning member 22 form a plurality of receiving grooves 30 on the surface of the substrate 10, and the plurality of receiving grooves 30 are interconnected. To improve the efficiency of the cover plate screen printing jig for processing the cover plate, the first positioning member 21 and the second positioning member 22 cooperate to form a plurality of receiving grooves 30. Furthermore, the plurality of receiving grooves 30 are interconnected, reducing the occupied area of ​​the second positioning member 22, making the cover plate screen printing jig compact and meeting the requirements of miniaturization.

[0024] In one embodiment, the first positioning member 21 is further provided with an escape groove 211, which is in communication with the receiving groove 30. Providing the escape groove 211 on the first positioning member 21 facilitates the placement and removal of the cover plate to be processed, while ensuring that the first positioning member 21 avoids the cover plate to be processed, further preventing the positioning member from interfering with the cover plate to be processed.

[0025] In one embodiment, the substrate 10 is further provided with mounting holes 60 around its periphery for mounting the cover plate screen printing jig on the screen printing machine. The design of the mounting holes 60 facilitates the installation of the cover plate screen printing jig, allowing the cover plate screen printing jig to be securely mounted on the screen printing machine.

[0026] In one embodiment, the substrate 10 is made of bakelite or stainless steel to ensure the stability and durability of the cover screen printing jig.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
