Technical Field

[0001] The invention belongs to the field of printers and relates to a method for realizing accurate positioning of a silk screen and a silk screen plate making machine. Background Art

[0002] The task of the screen plate making machine is to print patterns on the screen through the print head. The screen as the substrate is a soft synthetic fiber fabric. In order to make the soft screen unfold and flatten for printing, a screen frame can be connected to the edge of the screen. The screen frame is generally in the shape of a rectangular frame. However, there is a defect in the use of the screen frame: during the printing process, the screen will be slightly offset, resulting in the printed pattern being different from the original sample image. This is because the screen itself is ductile. Even if the edge of the screen is fixed, for example, when the print head presses the middle of the screen, the middle of the screen will sink.

[0003] The screen and screen frame have simple structures and are widely used in actual production, and are not suitable for modification. Therefore, improvements are made to the screen platemaking machine to solve this problem. Summary of the invention

[0004] In view of the above problems, the present invention provides a screen plate making machine capable of fixing the screen.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a method for realizing accurate positioning of a screen, comprising the following steps:

[0006] S1: Select a silicone pad with the same shape and area as the screen, apply table glue or stick table film on the silicone pad, use a blower to dry the table glue or let it dry naturally;

[0007] S2: Raise the print head of the screen plate making machine, and the lifting platform drives the fixed silicone pad to rise;

[0008] S3: Align the screen in the screen frame with the silicone pad, and then press the screen onto the silicone pad to fix the screen;

[0009] S4: Move the fixed tooling in the screen plate making machine to connect it with the screen frame and fix the screen frame;

[0010] S5: The print head is lowered and pressed onto the screen, followed by printing.

[0012] Preferably, the upper surface of the support platform has the same shape and area as the upper surface of the silicone pad, and the upper surface of the silicone pad has the same shape and area as the wire mesh.

[0013] Preferably, the main body comprises two longitudinal beams, and the two longitudinal beams pass through the gantry.

[0014] Preferably, a slide rail is connected above the longitudinal beam column, and a fixing tool is slidably connected above the slide rail.

[0015] Preferably, the fixing tool includes a top screw for pressing on the slide rail, and also includes a protrusion for engaging with the wire mesh frame.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] The present invention utilizes the characteristic that the table glue is not easy to fall off after being air-dried and pasted on the silicone pad. The silk screen is placed on the silicone pad so that the silk screen is pasted and fixed to prevent the silk screen from moving due to squeezing. At the same time, when the silk screen is peeled off, the table glue will not fall off the silicone pad. The table glue can be reused and no residue of the table glue will remain on the silk screen.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in order to prevent the screen from moving due to squeezing the screen during printing, a method for accurately positioning the screen includes the following steps:

[0029] S1: Select a silicone pad 7 with the same shape and area as the screen 101, apply a table glue or stick a table film on the silicone pad 7, use a blower to dry the table glue or let it dry naturally;

[0030] S2: Raise the print head 41 of the screen plate making machine, and the lifting platform drives the fixed silicone pad 7 to rise;

[0031] S3: Align the screen 101 in the screen frame 10 with the silicone pad 7, and then press the screen onto the silicone pad 7 to fix the screen;

[0032] S4: moving the fixed tool 8 in the screen plate making machine to connect it with the screen frame 10 and fix the screen frame 10;

[0033] S5: The print head 41 is lowered, and the print head 41 is pressed onto the screen, and then printing is performed.

[0034] Specifically, the present invention pastes the screen on the silicone pad 7. The silicone pad 7 not only supports but also sticks to the screen to prevent the screen from moving up and down and moving sideways, making the printed pattern less prone to errors. At the same time, the silicone pad 7 is conductive to prevent the static electricity generated by the friction between the print head 41 and the screen from damaging the print head 41. The platen glue is fixed on the silicone pad 7 after air drying. When the screen is removed, the platen glue remains on the silicone pad 7. After applying the platen glue once, the platen glue can be used multiple times.

[0035] In order to implement the method for accurately positioning the silk screen as mentioned above, a silk screen platemaking machine for realizing accurate positioning of the silk screen is provided, the silk screen platemaking machine comprises a main body 1, a linear motor module 2 is arranged on the main body 1, the linear motor module 2 is a commonly used component, and is used to drive other components to move linearly, a gantry 3 is connected above the linear motor module 2, a printing mechanism 4 is arranged on the upper part of the gantry 3, and the printing mechanism 4 comprises a print head 41.

[0036] In order to realize the lifting and lowering of the silicone pad 7, the main body 1 of the present invention is connected with a longitudinal beam plate 5, the longitudinal beam plate 5 passes through the gantry 3, and an electric lifting platform 6 is connected above the longitudinal beam plate 5. The electric lifting platform 6 includes a lifting plate 61 at the top, and a support platform 62 is connected above the lifting plate 61. The silicone pad 7 is connected above the support platform 62, and a table rubber layer is arranged on the upper side of the silicone pad 7 (not shown in the figure).

[0037] Specifically, compared with the existing screen platemaking machine, the rubber roller is eliminated in the present invention. The rubber roller is a component that moves with the print head 41 during printing and is used to support the screen. The area of ​​the silicone pad 7 in the present invention is larger than the rubber roller, and it supports the entire screen, so there is no need to move with the print head 41.

[0038] Furthermore, the upper surface of the support platform 62 has the same shape and area as the upper surface of the silicone pad 7, and the upper surface of the silicone pad 7 has the same shape and area as the screen, so as to complete the support of the entire screen.

[0039] Furthermore, the main body 1 includes two longitudinal beams 9 , and the two longitudinal beams 9 pass through the gantry 3 .

[0040] Furthermore, a slide rail 91 is connected to the top of the longitudinal beam column 9 , and a fixed tooling 8 is slidably connected to the top of the slide rail 91 .

[0041] Furthermore, the fixing tool 8 includes a top screw 81 for pressing on the slide rail 91. After the rotating top screw 81 is pressed on the slide rail 91, the fixing tool 8 is positioned. In addition, the fixing tool 8 also includes a protrusion 82 for connecting with the wire mesh frame 10. Grooves 102 are provided at both ends of the wire mesh frame 10.
