Description

Technical Field

[0001] The utility model relates to the technical field of automatic flat screen printing machines, in particular to a full-automatic flat screen printing machine with a three-color turntable and CCD detection. Background Art

[0002] The three-color turntable fully automatic flat screen printing machine is an automated equipment used for multi-color printing. The feature of this equipment is that it can print multiple colors through the rotation of the turntable. Specifically, it can print three different colors in sequence on the same workpiece. In multi-color printing, it is crucial to ensure that the position of each color pattern on the workpiece is accurate. Since there may be slight deviations in the screen printing process, CCD detection can monitor the positioning of the workpiece in real time and automatically adjust the position of the turntable or workpiece through the image recognition system to ensure that the printed layers of different colors can be accurately aligned to avoid misalignment or overlapping problems. Therefore, it is necessary to add a CCD detection system when the three-color turntable fully automatic flat screen printing machine is working.

[0003] Traditional three-color, turntable, CCD-based fully automatic flat-panel screen printers are typically mounted with their CCD detection systems fixed to the machine frame, preventing flexible adjustment of position and angle. Different printed products vary in shape, size, and printing position, making the existing fixed installation method difficult to meet the inspection requirements of a wide range of products. This results in a limited inspection range for printed products and can easily miss inspections of edge areas or special features. Therefore, those skilled in the art have provided a three-color, turntable, CCD-based fully automatic flat-panel screen printer to address the issues raised in the background art. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] Reference Figure 1-3This embodiment provides a three-color turntable with CCD detection fully automatic flat screen printing machine, including a frame 1, a horizontal adjustment structure and an angle adjustment structure, characterized in that two fixed plates 2 are fixedly connected to the top of the frame 1, a silk screen printing mechanism 3 is installed between the two fixed plates 2, a workbench 4 is fixedly connected inside the frame 1, a connecting plate 6 is fixedly connected to the frame 1, a horizontal adjustment structure is provided on one side of the connecting plate 6, and the connecting plate 6 is connected to the angle adjustment structure through the horizontal adjustment structure, a turntable mechanism 5 is installed inside the workbench 4, and a plurality of processing stations 23 are installed at the top of the workbench 4.

[0023] The horizontal adjustment structure includes a first threaded rod 9, a first threaded sleeve 10, a first guide rod 11, a slider 12 and a connecting box 13. One end of the connecting plate 6 is rotatably connected to the first threaded rod 9, and the first threaded sleeve 10 is threadedly connected to the first threaded rod 9. One end of the connecting plate 6 is fixedly connected to the first guide rod 11, and the slider 12 is slidably connected to the first guide rod 11, and a connecting box 13 is fixedly connected between the first threaded sleeve 10 and the slider 12.

[0024] The connecting plate 6 is fixedly connected to the first fixing box 7 at one end away from the first threaded sleeve 10, and the first motor 8 is installed inside the first fixing box 7, and one end of the first threaded rod 9 passes through the first fixing box 7 and is connected to the output end of the first motor 8.

[0025] When the present embodiment is in use, the silk-screen printing mechanism 3 is installed between the two fixed plates 2 for printing work. The silk-screen printing mechanism 3 can print and process the workpiece located on the workbench 4. The principle and use process of the silk-screen printing mechanism 3 are the same as those in the prior art and will not be described in detail here. The turntable mechanism 5 inside the workbench 4 drives the workpiece placed on the top processing station 23 of the workbench 4 to rotate, so that the workpiece passes through different processing positions in turn for silk-screening operations. The turntable mechanism 5 can rotate the workpiece so that the workpiece is rotated to different workpieces. The principle and use process of the turntable mechanism 5 are the same as those in the prior art and will not be described in detail here. Through this turntable working mode, multi-color printing can be efficiently performed on the workpiece. When the horizontal position of the CCD camera 22 needs to be adjusted, When the first motor 8 is turned on, the first motor 8 drives the first threaded rod 9 to rotate, and the first threaded sleeve 10 moves on the first threaded rod 9. Since the first threaded sleeve 10 and the slider 12 are fixedly connected by the connecting box 13, and the slider 12 slides along the first guide rod 11, this linkage structure enables the connecting box 13 to move smoothly in the horizontal direction, thereby moving the CCD camera 22 to the appropriate position, ensuring that all parts of the workpiece can be fully inspected and blind spots can be avoided. The device can adapt to the inspection needs of printed products of different sizes and positions. When facing printed products of different batches and specifications, there is no need to reinstall or adjust the entire inspection device. The camera can be quickly aligned with the inspection area through horizontal adjustment, which improves the efficiency and adaptability of the inspection. Example 2

[0026] Reference Figure 4 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that the angle adjustment structure includes a second threaded rod 16, a second guide rod 17, a second threaded sleeve 18, an active rack 19, a rotating shaft 20, an incomplete gear 21 and a CCD camera 22. The second threaded rod 16 is rotatably connected to the inside of the connecting box 13, the second guide rod 17 is fixedly connected to the inside of the connecting box 13, the second threaded sleeve 18 is threadedly connected to the second threaded rod 16, and the bottom end of the second threaded sleeve 18 is fixedly connected to the active rack 19.

[0027] The connection box 13 has a rotating shaft 20 rotatably connected therein, an incomplete gear 21 fixedly connected to the rotating shaft 20 , and the active rack 19 is meshedly connected to the incomplete gear 21 , and a CCD camera 22 is mounted on the rotating shaft 20 .

[0028] One end of the connection box 13 is fixedly connected to the second fixing box 14 , and the second motor 15 is installed inside the second fixing box 14 . One end of the second threaded rod 16 passes through the second fixing box 14 and is connected to the output end of the second motor 15 .

[0029] During use of this embodiment, when the angle of the CCD camera 22 needs to be adjusted, the second motor 15 is activated. The output end of the second motor 15 drives the second threaded rod 16 to rotate. Since the second threaded sleeve 18 is threadedly connected to the second threaded rod 16, the second threaded sleeve 18 moves linearly on the second threaded rod 16. The active rack 19 fixedly connected to the bottom end of the second threaded sleeve 18 moves along with the second threaded sleeve 18. The active rack 19 meshes with the incomplete gear 21. When the active rack 19 moves, it drives the incomplete gear 21 to rotate. The rotating shaft 20 is fixedly connected to the incomplete gear 21, so the rotating shaft 20 rotates along with the incomplete gear 21. The CCD camera 22 is mounted on the rotating shaft 20. This allows the CCD camera 22 to adjust its angle, allowing it to inspect printed workpieces from different angles. For printed products with complex shapes or three-dimensional structures, the printed pattern can be observed from multiple angles to comprehensively check whether the pattern is complete and has no defects. The angle adjustment structure allows the CCD camera 22 to flexibly change its shooting angle. This enables the camera to inspect the printed product from different viewing angles.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
