Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, specifically to a single-sided automatic screen printing machine. Background Technology

[0002] Currently, screen printing involves first creating a screen printing plate of the text or image to be printed, which is then mounted on a screen printing machine. A squeegee then forces ink through the screen printing plate onto the substrate (such as textiles, metal plates, plastics, leather templates, glass, and ceramics), thus screen printing the same text or image as the screen printing plate onto the substrate.

[0003] Existing traditional single-sided automatic screen printing machines on the market have a linear production line layout, resulting in a large footprint that makes them unsuitable for production environments with limited space. In addition, during actual production, small amounts of impurities (dust and particulate matter) often adhere to the surface of the substrate, which can interfere with the screen printing process, affecting the adhesion of ink to the workpiece surface and the printing accuracy. Traditional single-sided automatic screen printing machines do not have a dust removal mechanism for cleaning the surface of the substrate, and rely on manual wiping for dust removal, which can lead to missed or incomplete wiping, resulting in unstable screen printing quality.

[0004] Therefore, the applicant hereby proposes a single-sided automatic screen printing machine to solve the aforementioned problems. Utility Model Content

Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a single-sided automatic screen printing machine for sequentially performing dust removal, screen printing of text or patterns, and curing on the screen printing surface of a substrate. It includes a frame 1, a turntable mechanism 2 for placing and conveying the substrate, a dust removal mechanism 3 for cleaning impurities from the screen printing surface, a screen printing mechanism 4 for screen printing text or patterns on the substrate, a material transfer mechanism 5 for transferring materials, a material unloading mechanism 6, and a control console 8 for adjusting and setting the working parameters of the turntable mechanism 2, dust removal mechanism 3, screen printing mechanism 4, material transfer mechanism 5, and material unloading mechanism 6. The turntable mechanism 2 is located at the front end of the frame 1, and the dust removal mechanism 3 and material transfer mechanism 5 are respectively... The screen printing mechanism 4 is located on the right and left sides of the turntable mechanism 2 on the frame 1, and the unloading mechanism 6 is located on the rear side of the turntable mechanism 2 on the frame 1. The front side of the frame 1 is also equipped with a control console 8. The screen printing mechanism 4 is located on the rear side of the turntable mechanism 2 on the frame 1. The screen printing mechanism 6 is located on the left side of the frame 1. The screen printing mechanism adopts a surrounding parallel layout (the dust removal mechanism, screen printing mechanism and material transfer mechanism are all arranged around the turntable mechanism on the frame, and the unloading mechanism is arranged in parallel on one side of the frame), which greatly reduces the size of the equipment and can be used in production environments with limited space. The dust removal mechanism can quickly remove dust from the screen printing surface of the substrate, avoiding the influence of impurities on the screen printing process. This not only improves the efficiency of screen printing but also ensures the quality of screen printing.

[0022] The turntable mechanism 2 includes a turntable 21 for conveying and rotating the printing substrate, a fixture seat 22 for positioning the printing substrate, and a placement cavity 23 for accommodating the printing substrate. The turntable 21 is rotatably mounted on the front end of the frame 1. Specifically, the turntable 21 is driven to rotate by a turntable driver located inside the frame 1, and the turntable driver is a servo motor. Several fixture seats 22 are arranged in a ring at equal intervals on the turntable 21. In this embodiment, four fixture seats are preferred, and they are arranged sequentially in a counterclockwise direction as a loading station, a dust removal station, a screen printing station, and a material transfer station. Each fixture seat 22 is provided with several placement cavities 23. The dust removal mechanism 3 includes a guide rail 31, a Y-axis linear drive module 32, a displacement seat 33, a mounting plate 34, a lifting driver 35, and a dust collector 36. The guide rail 31 and the Y-axis linear drive module 32 are arranged longitudinally side by side on the right side of the frame 1. The displacement seat 33 is slidably mounted on the guide rail 31, and its outer side is connected to the output end of the Y-axis linear drive module 32. The displacement seat 33 is provided with a mounting plate 34, and a lifting driver 35 is fixedly mounted on the top side of the mounting plate 34. In this embodiment, the lifting driver 35 is preferably a cylinder. The output end faces downward and is connected to a dust collector 36; the Y-axis linear drive module 32 drives the displacement seat 33 to move linearly at a constant speed along the guide rail 31, while the output end of the lifting driver 35 on the mounting plate 34 drives the dust collector 36 to descend, so that the working end of the dust collector 36 rolls into contact with the screen printing surface of the substrate to achieve the dust removal effect; after the dust removal is completed (i.e., the set maximum stroke value is reached), the output end of the lifting driver 35 will drive the dust collector 36 to rise until it reaches a safe height, and then the Y-axis linear drive module 32 will drive the displacement seat 33 to move linearly at a constant speed along the guide rail 31 to reset to the origin.

[0023] The dust collector 36 includes a buffer plate 361, buffer rods 362, buffer springs 363, a U-shaped fixing frame 364, a cleaning roller 365, and a dust removal roller 366. The upper side of the buffer plate 361 is connected to the output end of the lifting drive 35. Buffer rods 362 are vertically slidably mounted on both ends of the buffer plate 361. The lower ends of the buffer rods 362 are fixedly connected to the top surface of the fixing frame 364. Buffer springs 363 are sleeved on the buffer rods 362 between the buffer plate 361 and the fixing frame 364. The cleaning roller 365 and the dust removal roller 366 are sequentially and laterally rotatable within the open end of the fixing frame 364. The dust roller 366 and the fixing frame 364 are detachable for easy cleaning and replacement. In this embodiment, the cleaning roller 365 is preferably a dust-adhesive paper roller, and the dust removal roller 366 is preferably a dust-adhesive rubber roller. The working end of the lifting driver 35 drives the buffer plate 361 to move the fixing frame 364 down through the buffer rod 362 until the dust removal roller 366 rolls into contact with the screen printing surface of the product to be screen printed, removing impurities from the screen printing surface. At the same time, the cleaning roller 365 rolls into contact with the outer surface of the dust removal roller 366, removing impurities from the dust removal roller 366. The buffer spring 363 is used to buffer the downward pressure to prevent the product to be screen printed from being damaged due to overload.

[0024] The screen printing mechanism 4 is existing technology, so it will not be described in detail here.

[0025] The material transfer mechanism 5 includes a material transfer base 51, an X-axis linear drive module 52, a material transfer frame 53, a material transfer driver 54, a material transfer plate 55, and suction nozzles 56. The material transfer base 51 is located on the left side of the front end of the frame 1. The X-axis linear drive module 52 is horizontally arranged on the material transfer base 51. The output end of the X-axis linear drive module 52 is connected to the material transfer frame 53. The top side of the material transfer frame 53 is connected to the material transfer driver 54. In this embodiment, the material transfer driver 54 is preferably a cylinder. The output end of the material transfer driver 54 faces downward and is connected to the material transfer plate 55. The material transfer plate 55 has a plurality of suction nozzles 56 arranged in a matrix at equal intervals. The suction nozzles 56 are connected to a vacuum generator located inside the frame 1. The material transfer frame is driven by the X-axis linear drive module 52. The transfer rack 53 moves back and forth linearly at a constant speed along the X-axis. When the transfer rack 53 moves linearly to the transfer station, the output of the transfer driver 54 drives the transfer plate 55 to lower the suction nozzle 56 until it contacts the screen printing surface of the substrate. Then, the vacuum generator in the frame 1 is activated, which makes the suction nozzle 56 firmly adsorb and grab the substrate. The output of the transfer driver 54 drives the transfer plate 55 to raise the suction nozzle 56 until the substrate is completely removed from the placement cavity 23. Then, the X-axis linear drive module 52 drives the transfer rack 53 to move linearly above the unloading mechanism 6. The output of the transfer driver 54 drives the transfer plate 55 to lower the suction nozzle 56 to a safe height. Then, the vacuum generator in the frame 1 is turned off, the suction nozzle 56 loses its adsorption force, and the substrate falls onto the unloading mechanism 6.

[0026] In this embodiment, the feeding mechanism 6 is preferably a conveyor belt; it is used to feed and transport the substrate.

[0027] The present invention provides a single-sided automatic screen printing machine, which further includes a curing mechanism 7 located above the conveying end of the unloading mechanism 6; the curing mechanism 7 includes a UV lamp box 71 and an baking oven 72 arranged sequentially above the conveying end of the unloading mechanism 6; used to cure the text or pattern screen-printed on the screen-printed surface of the substrate conveyed by the unloading mechanism 6.

[0028] The control console 8 includes a PLC human-machine interface component 81, control buttons 82, and position sensors (not shown in the figure). The PLC human-machine interface component 81 is located on the front side of the frame 1, and the control buttons 82 are located on the frame 1 on one side of the PLC human-machine interface component 81. Position sensors are provided on the movable ends of the turntable mechanism 2, dust removal mechanism 3, screen printing mechanism 4, material transfer mechanism 5, unloading mechanism 6, and curing mechanism 7 on the frame 1 to detect whether the movement of each component is in place.

[0029] See attached document Figure 6As shown, the working principle of this utility model is as follows: Based on the screen printing process of the substrate, after adjusting and setting the working parameters of the turntable mechanism 2, dust removal mechanism 3, screen printing mechanism 4, material transfer mechanism 5, unloading mechanism 6, and curing mechanism 7 through the control console 8, the turntable mechanism 2 is set to rotate counterclockwise at a uniform speed. The four fixture seats 22 on it correspond to the loading station, dust removal station, screen printing station, and material transfer station respectively. The substrate material is clamped and placed on the loading station by an automatic loading machine or manually. The turntable mechanism 2 feeds the substrate material into the dust removal station. Inside the dust removal station, the dust removal mechanism 3 removes dust from the screen printing surface of the substrate material. The turntable mechanism 2 sends the dust-removed substrate material into the screen printing station. The screen printing mechanism 4 screen prints text or patterns on the screen printing surface of the substrate material in the screen printing station. The turntable mechanism 2 sends the screen-printed substrate material to the transfer station. The transfer mechanism 5 picks up the substrate material in the transfer station and sends it into the unloading mechanism 6. The unloading mechanism 6 sends it into the curing mechanism 7 for curing treatment. After the curing treatment is completed, the material is unloaded.
