Description

Technical Field

[0001] This invention relates to the field of screen printing machine technology, and specifically to a rotary screen printing machine with adjustable function. Background Technology

[0002] A rotary screen printing machine is an automated device that enables continuous screen printing of workpieces through a rotary multi-station rotation. It is widely used for printing surface patterns, text, and markings on electronic components, plastic shells, glass products, metal nameplates, and other products.

[0003] In the existing technology, most rotary screen printing machines adopt a fixed installation structure for the screen printing mechanism. The screen printing base and the machine are rigidly connected, which cannot be flexibly adjusted according to the size, thickness and printing position requirements of the workpiece. Although some improved equipment has added a manual adjustment structure, it can only achieve coarse adjustment of one or two axes. The adjustment accuracy is low and the operation is cumbersome. When changing to different specifications of workpieces, it is necessary to stop the machine for several hours of manual calibration, which seriously affects the production changeover efficiency.

[0004] Meanwhile, manual adjustment relies on the operator's experience level, making it difficult to ensure the consistency of printing position for each batch of products. This can easily lead to defects such as printing misalignment, ghosting, missing prints, and uneven printing pressure, resulting in low product yield.

[0005] In addition, mechanical wear will occur after the equipment has been running for a long time, which will cause positional deviation between the screen printing frame and the workpiece. Traditional equipment cannot achieve real-time online compensation and must be stopped for disassembly and adjustment, which further reduces the uptime of the equipment and cannot meet the needs of modern high-precision, large-volume and multi-variety production.

[0038] The present invention will be further described in conjunction with the following embodiments.

[0039] Depend on Figures 1 to 8 As can be seen, the rotary screen printing machine with adjustment function described in this embodiment includes a machine base 1; the machine base 1 is provided with a material tray conveying mechanism, a rotating table 2 and a material picking mechanism; the machine base 1 is provided with an alignment mechanism, a dust removal mechanism, a screen printing mechanism and a sampling inspection mechanism in sequence along the rotation direction of the rotating table 2; the material picking mechanism is used to drive the material to move between the material tray conveying mechanism, the rotating table 2 and the sampling inspection mechanism;

[0040] The screen printing mechanism includes a mounting plate 3 fixedly connected to the machine base 1, an adjusting plate 4 slidably disposed on the top of the mounting plate 3, a lifting plate 5 movably disposed on the bottom of the adjusting plate 4, and a screen printing base 6 fixedly connected to the lifting plate 5; the lifting plate 5 is movably disposed on the bottom of the mounting plate 3; the adjusting plate 4 is disposed on the bottom of the rotating table 2; the screen printing base 6 is disposed on the top of the rotating table 2; the screen printing base 6 is provided with a scraper 61 and a screen printing frame 62;

[0041] The adjusting plate 4 is provided with a lifting adjusting component for driving the lifting plate 5 to move up and down; the mounting plate 3 is provided with a lateral adjusting component for driving the adjusting plate 4 to move along the X-axis direction; the mounting plate 3 is provided with a longitudinal adjusting component for driving the adjusting plate 4 to move along the Y-axis direction.

[0042] Specifically, in this embodiment, the rotary screen printing machine with adjustment function is operated by conveying the glass to be screen printed to the material picking station by the material tray conveying mechanism. The material picking mechanism picks up the glass and places it on the corresponding station of the rotary table 2. The rotary table 2 rotates intermittently, sequentially conveying the glass to the alignment station, dust removal station, screen printing station and sampling inspection station to complete the entire process.

[0043] During screen printing, the lifting adjustment component drives the screen printing base 6 to move up and down along the Z-axis to adapt to glass of different thicknesses. The horizontal adjustment component and the vertical adjustment component drive the screen printing base 6 to move along the X-axis and Y-axis respectively to accurately match the printing position on the glass, realizing independent or linked automatic adjustment of the three axes.

[0044] This embodiment integrates a lifting adjustment component, a horizontal adjustment component, and a vertical adjustment component into the screen printing mechanism, which can drive the screen printing base 6 to perform independent or linked automatic adjustments along the Z-axis, X-axis, and Y-axis respectively, without the need for manual operation and with high adjustment accuracy.

[0045] In this embodiment, a rotary screen printing machine with an adjustable function is provided with a screen printing guide rod 51 between the top of the lifting plate 5 and the bottom of the screen printing seat 6; the adjusting plate 4 is provided with a screen printing guide sleeve 47; and the screen printing guide rod 51 is slidably sleeved on the screen printing guide sleeve 47.

[0046] Specifically, when the lifting adjustment component drives the lifting plate 5 to adjust the screen printing seat 6 in the Z-axis direction, the screen printing guide rod 51 moves up and down synchronously with the screen printing seat 6 and slides smoothly along the axial direction in the screen printing guide sleeve 47, providing guidance and constraint for the lifting movement of the screen printing seat 6, effectively eliminating radial sway and wobble during the lifting process of the screen printing seat 6, and ensuring that the screen printing frame 62 remains parallel to the glass surface.

[0047] This embodiment describes a rotary screen printing machine with an adjustable function. The lifting and adjusting assembly includes a drive plate 7 located at the bottom of a lifting plate 5, a lifting and adjusting motor 71 located on the drive plate 7, a lifting and adjusting screw 72 connected to the output end of the lifting and adjusting motor 71, a lifting and adjusting nut 73 sleeved on the lifting and adjusting screw 72, and a lifting and adjusting guide rod 74 fixedly located between the drive plate 7 and the adjusting plate 4. The lifting and adjusting nut 73 is fixedly connected to the lifting plate 5. One end of the lifting and adjusting screw 72 is connected to the output end of the lifting and adjusting motor 71. The other end of the lifting and adjusting screw 72 is rotatably connected to the adjusting plate 4.

The lifting and adjusting guide rod 74 is slidably sleeved on the lifting and adjusting guide sleeve 52.

[0048] Specifically, when adjusting the screen printing base 6 and the screen printing frame 62 along the Z-axis, the lifting adjustment motor 71 receives a signal from the control system and starts to drive the lifting adjustment screw 72 to rotate. The rotational motion is converted into linear motion through the threaded transmission between the lifting adjustment screw 72 and the lifting adjustment nut 73, which drives the lifting plate 5 to move up and down along the lifting adjustment guide rod 74, thereby driving the screen printing base 6 and the screen printing frame 62 to lift. The lifting adjustment guide rod 74 slides in the lifting adjustment guide sleeve 52 to provide auxiliary guidance for the movement of the lifting plate 5.

[0049] This embodiment describes a rotary screen printing machine with an adjustment function. The horizontal adjustment assembly includes a first horizontal slider 31, a second horizontal slider 32, and a third horizontal slider 33.

The second horizontal slider 32 is slidably mounted on the top of the first horizontal slider 31 along the X-axis direction. The third horizontal slider 33 is slidably mounted on the top of the second horizontal slider 32 along the Y-axis direction. The top of the third horizontal slider 33 is fixedly connected to the adjustment plate 4.

[0050] The lateral adjustment assembly further includes a lateral adjustment screw 34 rotatably mounted on the mounting plate 3 along the X-axis, a lateral adjustment nut 35 sleeved on the lateral adjustment screw 34, and a lateral adjustment motor 36 fixedly mounted on the mounting plate 3; the output end of the lateral adjustment motor 36 is connected to the lateral adjustment screw 34; and the lateral adjustment nut 35 is fixedly connected to the second lateral slider 32.

[0051] Specifically, when adjusting the screen printing base 6 and the screen printing frame 62 in the X-axis direction, the horizontal adjustment motor 36 is started, driving the horizontal adjustment screw 34 to rotate. Through the threaded transmission between the horizontal adjustment screw 34 and the horizontal adjustment nut 35, the second horizontal slider 32 is driven to slide along the first horizontal slider 31 in the X-axis direction. Then, the third horizontal slider 33 drives the adjustment plate 4 and the entire screen printing base 6 to move in the X-axis direction. The third horizontal slider 33 can slide freely on the second horizontal slider 32 in the Y-axis direction without interfering with the movement of the vertical adjustment component.

[0052] This embodiment describes a rotary screen printing machine with an adjustable function. The longitudinal adjustment assembly includes a first longitudinal slider 41, a second longitudinal slider 42, and a third longitudinal slider 43. The first longitudinal slider 41 is fixedly mounted on the top of the mounting plate 3. The second longitudinal slider 42 is slidably mounted on the top of the first longitudinal slider 41 along the Y-axis direction. The third longitudinal slider 43 is slidably mounted on the top of the second longitudinal slider 42 along the X-axis direction. The top of the third longitudinal slider 43 is fixedly connected to the adjustment plate 4.

[0053] The longitudinal adjustment assembly also includes a longitudinal adjustment screw 44 rotatably mounted on the mounting plate 3 along the Y-axis, a longitudinal adjustment nut 45 sleeved on the longitudinal adjustment screw 44, and a longitudinal adjustment motor 46 fixedly mounted on the mounting plate 3; the output end of the longitudinal adjustment motor 46 is connected to the longitudinal adjustment screw 44; and the longitudinal adjustment nut 45 is fixedly connected to the second longitudinal slider 42.

[0054] Specifically, when adjusting the screen printing base 6 and the screen printing frame 62 in the Y-axis direction, the longitudinal adjustment motor 46 is started, driving the longitudinal adjustment screw 44 to rotate. Through the threaded transmission between the longitudinal adjustment screw 44 and the longitudinal adjustment nut 45, the second longitudinal slider 42 is driven to slide along the first longitudinal slider 41 in the Y-axis direction. Then, the third longitudinal slider 43 drives the adjustment plate 4 and the entire screen printing base 6 to move in the Y-axis direction. The third longitudinal slider 43 can slide freely on the second longitudinal slider 42 in the X-axis direction without interfering with the movement of the transverse adjustment component.

[0055] The rotary screen printing machine with adjustment function described in this embodiment further includes a longitudinal moving screen printing linear module 63 disposed along the Y-axis direction on the screen printing base 6 and a lifting screen printing linear module 64 disposed along the Z-axis direction at the output end of the longitudinal moving screen printing linear module 63.

[0057] Specifically, during screen printing, the lifting screen printing linear module 64 first drives the squeegee 61 to descend to the ink surface inside the screen printing frame 62 and applies a preset printing pressure; then the longitudinal moving screen printing linear module 63 drives the squeegee 61 to move at a constant speed along the Y-axis, scraping the ink inside the screen printing frame 62 through the screen onto the glass surface; after completing one scraping, the lifting screen printing linear module 64 drives the squeegee 61 to rise and reset, and the longitudinal moving screen printing linear module 63 drives the squeegee 61 back to the initial position.

[0058] The rotary screen printing machine with adjustment function described in this embodiment includes a material tray conveying mechanism comprising a material tray conveying belt 11 disposed along the Y-axis direction on the machine base 1; and a material picking mechanism comprising a multi-axis robot 12 disposed on the machine base 1, an adsorption plate 13 disposed at the output end of the multi-axis robot 12, and a vacuum nozzle 14 disposed on the adsorption plate 13.

[0059] Specifically, once the screen-printed glass is neatly stacked in the tray, the tray is transported to the picking station along the Y-axis by the tray conveyor belt 11; the multi-axis robot 12 moves the adsorption plate 13 above the tray, and the vacuum nozzle 14 generates negative pressure to adsorb the upper surface of the glass, removing the glass from the tray and placing it stably on the corresponding station of the rotating table 2; after processing, the multi-axis robot 12 removes the qualified glass from the rotating table 2 and puts it back into the tray.

[0060] The rotary screen printing machine with adjustment function described in this embodiment has a rotating table 2 through which a horizontal alignment groove 21 and a vertical alignment groove 22 are provided.

[0061] The alignment mechanism includes an alignment plate 8 that is movably and vertically mounted at the bottom of the rotating platform 2; the alignment plate 8 is slidably provided with a first transverse sliding plate 81 and a second transverse sliding plate 82 along the X-axis direction; the first transverse sliding plate 81 is provided with a first transverse alignment rod 83; the second transverse sliding plate 82 is provided with a second transverse alignment rod 84; the first transverse alignment rod 83 and the second transverse alignment rod 84 are respectively movably inserted through the transverse alignment groove 21;

[0063] Specifically, when the rotating table 2 transports the glass to the alignment station, the alignment plate 8 rises, causing the first transverse alignment rod 83 and the second transverse alignment rod 84 to pass through the transverse alignment groove 21, and the first longitudinal alignment rod 93 and the second longitudinal alignment rod 94 to pass through the longitudinal alignment groove 22 and extend out of the surface of the rotating table 2; then the first transverse sliding plate 81 and the second transverse sliding plate 82 move towards each other along the X-axis, causing the first transverse alignment rod 83 and the second transverse alignment rod 84 to clamp the left and right sides of the glass; the first longitudinal sliding plate 91 and the second longitudinal sliding plate 92 move towards each other along the Y-axis, causing the first longitudinal alignment rod 93 and the second longitudinal alignment rod 94 to clamp the front and rear sides of the glass, thus achieving center alignment of the glass.

[0064] The rotary screen printing machine with adjustment function described in this embodiment has a alignment plate 8 with a transverse alignment synchronous belt 86 arranged along the X-axis direction; the alignment plate 8 has a transverse alignment motor 85 for driving the transverse alignment synchronous belt 86 to move; the first transverse slide plate 81 and the second transverse slide plate 82 are respectively connected to both sides of the transverse alignment synchronous belt 86.

[0067] Specifically, during glass alignment, the alignment cylinder 98 extends, driving the alignment plate 8 to rise to the working position; the transverse alignment motor 85 starts, driving the transverse alignment timing belt 86 to rotate. Since the first transverse sliding plate 81 and the second transverse sliding plate 82 are respectively connected to the left and right sides of the transverse alignment timing belt 86, the operation of the transverse alignment timing belt 86 will drive the first transverse sliding plate 81 and the second transverse sliding plate 82 to move synchronously towards or away from each other along the X-axis; similarly, the longitudinal alignment motor 95 starts, driving the longitudinal alignment timing belt 96 to rotate, driving the first longitudinal sliding plate 91 and the second longitudinal sliding plate 92 to move synchronously towards or away from each other along the Y-axis; after alignment is completed, the alignment cylinder 98 retracts, driving the alignment plate 8 to descend and reset, and the rotating table 2 continues to rotate.

After dust removal, the glass is transported to the screen printing station for screen printing. After screen printing, the rotary table 2 transports the glass to the sampling inspection station. The sampling linear module 17 drives the sampling tray 18 to move to the corresponding station. The material handling mechanism places the glass to be inspected on the sampling tray 18, and the sampling inspection system performs appearance and printing quality inspection.
