Description

Technical Field

[0001] The utility model relates to the technical field of screen printing equipment, in particular to a screen printing machine screen frame component which is easy to disassemble, assemble and clean. Background Art

[0002] The full name of the screen printer is a screen printer, which is a device that prints solder paste or patch glue onto the pad through the screen. After the screen printing is completed, the screen frame and the screen inside the screen frame will be contaminated with solder paste or patch glue and other printed materials. In order to ensure the quality of printing, the screen frame and screen need to be cleaned frequently. At present, the screen frame is usually installed on the screen printer by multiple bolts or by using a threaded rod to drive the extrusion block to tighten and fix it. Therefore, when the screen frame needs to be disassembled and cleaned, the staff needs to manually tighten multiple bolts to remove the screen frame, and after cleaning, it is also necessary to tighten multiple bolts to install it, which greatly increases the disassembly time of the screen frame, and the bolts are prone to slipping after multiple disassembly and assembly, which further brings inconvenience to the disassembly of the screen frame.

[0003] In response to the above problem, a Chinese patent announcement with announcement number CN219405751U discloses a screen frame assembly for a screen printer that is easily disassembled, assembled, and cleaned. The technical key points are: it includes a screen printer body, a printing frame is fixedly connected to the front of the screen printer body, a mounting frame is fixedly connected to the printing frame, a screen frame is arranged between the two mounting frames, a screen is fixedly connected to the inner side of the screen frame, a connecting cover is fixedly connected to the left and right sides of the bottom end of the mounting frame, a cavity is provided inside the connecting cover, a fixing mechanism is arranged inside the cavity, a dovetail plug is fixedly connected to the left and right sides of the screen frame, a first magnet is fixedly connected to the rear side of the dovetail plug, the fixing mechanism includes a slider, a pull rod, a fixing rod, and a spring, and the slider is slidably connected in the cavity.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: although the device can easily disassemble and assemble the screen frame, it is inconvenient to disassemble, replace and clean the screen, which may easily lead to waste materials remaining on the screen and affect the printing quality. Therefore, we propose a screen printing machine screen frame assembly that is easy to disassemble and clean to solve the above problems. Utility Model Content
