[0039] The following is a detailed description of a double-station printing tooling of the utility model through specific embodiments.

[0040] like Figures 1 to 4 As shown, the utility model provides a double-station printing tool for printing an indication mark on an indication window of a occluding hemostasis system to replace manual pasting of an indication sticker.

[0041] The invention comprises a first bracket 100, a first base 200 and a light shield 300, wherein:

[0042] The first bracket 100 is higher than the first base 200. An X-axis moving assembly 400 is fixedly mounted on the first bracket 100. A print head 401 is disposed on the X-axis moving assembly 400. The print head 401 can move back and forth along the X-axis direction driven by the X-axis moving assembly 400. A wire harness and an ink pipeline connected to the print head 401 are also disposed on the first bracket 100. The wire harness provides power and control signals for the print head 401. The ink pipeline is connected to an ink cartridge independently disposed outside to provide ink for the print head 401.

[0043] Two first bases 200 are arranged in parallel, each of which is equipped with a Y-axis moving assembly 500, on which a slide 501 is arranged. The slide 501 moves along the Y-axis direction driven by the Y-axis moving assembly 500, and a concave mold for placing a printing object is arranged on the upper surface of the slide 501;

[0044] The first bracket 100 is located in the light shield 300, and the first base 200 and the end of the Y-axis moving assembly 500 away from the first bracket 100 extend out of the light shield 300, so that the slide 501 can enter and exit the light shield 300, and a control panel can be installed on the front of the light shield 300 for setting printing parameters and monitoring device status;

[0045] There are two print heads 401 and two slides 501 . When printing, the print head 401 is moved by the X-axis moving component 400 , and the slide 501 is moved by the Y-axis moving component 500 , so that the print head 401 faces the slide 501 .

[0046] like Figure 2 As shown, the X-axis moving assembly 400 includes a first screw rod 402, a first servo motor 403 and two sliders 404. The first screw rod 402 is fixedly mounted on the first bracket 100. The first servo motor 403 is used to drive the first screw rod 402. As the first screw rod 402 rotates, the slider 404 moves synchronously on the first screw rod 402 and drives the print head 401 to move.

[0047] The Y-axis moving assembly 500 includes a second screw rod 502 , a slide rail 503 , and a second servo motor 504 . The second servo motor 504 is used to drive the second screw rod 502 . As the second screw rod 502 rotates, the slide 501 moves along the slide rail 503 driven by the second screw rod 502 .

[0048] like Figure 3 As shown, in a preferred embodiment of the utility model, in order to enable the print head 401 to be accurately aligned with the printing object on the slide 501, a positioning device 405 is provided on the print head 401. The positioning device 405 is a CCD camera, and its shooting direction is vertically downward. After the CCD camera acquires the image, it is uploaded to the PLC or the host computer for image recognition, and the relative position of the print head 401 and the printing object is determined according to the recognition result, and the position of the print head 401 on the X-axis is adjusted based on the position.

[0049] In addition, if the position of the slide 501 is offset, resulting in the print head 401 still being unable to align with the print object when it intersects the Y axis, the offset of the slide 501 on the Y axis can be determined based on the recognition result, and the position of the slide 501 can be adjusted.

[0050] In a preferred embodiment of the utility model, the print head 401 uses UV curing ink, and a UV curing lamp 406 is also provided on the print head 401. When printing, one color is printed first, and UV curing is performed using the UV curing lamp 406, and then another color is printed. After all colors are printed, a varnish is printed and UV curing is performed to keep the colors bright and stable.

[0051] Compared with ordinary color inks, the UV curing ink used in this application has higher color fastness, stable color, is not easily affected by the sterilization process, and can form a cured surface layer, making the coating harder and the color more transparent and bright.

[0052] like Figure 2 As shown, a lifting assembly 407 is provided at the connection between the X-axis moving assembly 400 and the print head 401 for adjusting the height of the print head 401. The lifting assembly 407 can adopt an electric push rod, which has the advantages of simple structure, small size and precise displacement.

[0053] During the printing process, the wiring harness and ink pipeline will move continuously under the drive of the print head 401. In order to avoid interference of the wiring harness and ink pipeline with other components, such as Figure 3 As shown, in a preferred embodiment of the utility model, a drag chain 600 is provided on the first bracket 100, and a guide groove 601 for accommodating the drag chain 600 is provided, the guide groove 601 is arranged parallel to the first screw rod 402, the wiring harness and the ink pipeline pass through the drag chain 600, and the wiring harness and the ink pipeline are constrained within a certain range by the drag chain 600 during the movement by the fixation of the drag chain 600, which can prevent the speed limiter and the ink pipeline from becoming scattered or rubbing against each other after movement, thereby providing equipment reliability and stability and extending equipment life.

[0054] When printing the indicator windows of the occluding hemostasis system, several indicator windows to be printed are placed on the concave mold on the upper surface of the slide 501 and aligned in the same direction. Then, the start button on the light shield 300 is pressed to make the slide 501 enter the light shield 300. At the same time, the print head 401 also starts to move to the initial printing position. After the slide 501 and the print head 401 stop moving, the positioning device 405 acquires the image and determines the relative positions of the print head 401 and the slide 501, and fine-tunes their positions respectively to make the print head 401 and the slide 501 completely aligned. Then, the printing program is started. After printing is completed, the slide 501 sends the printed indicator window out of the light shield 300.

[0055] During the printing process, two workstations perform printing operations alternately. When one workstation is printing, the slide 501 of the other workstation moves to the outside of the light shielding hood 300. At this time, the sample to be printed is placed on the slide 501. After placement, wait for the other workstation to complete printing. Then the slide 501 sends the sample into the light shielding hood 300, and the other slide 501 sends the printed sample out of the light shielding hood 300 to improve printing efficiency.

[0056] In summary:

[0057] The utility model adopts the method of directly printing the indicator mark on the indicator window instead of manually pasting the indicator sticker, thereby solving the problem of large error in the mark position during manual pasting, avoiding the problem of rework caused by skewed and misaligned pasting, and significantly improving the production efficiency of the indicator window.

[0058] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
