[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a pre-positioning silk screen printing device.

[0025] The utility model provides Figure 1-3 A pre-positioning screen printing device shown includes a screen printing machine 1 and a support frame 2 fixedly arranged on the top of the screen printing machine 1, a high-definition camera 3 is fixedly arranged at the bottom of the upper end of the support frame 2, a protective cover 4 is arranged on the outer cover of the high-definition camera 3, mounting plates 20 are fixedly arranged on the upper ends of both sides of the outer wall of the protective cover 4, mounting bolts 21 are screwed between the mounting plate 20 and the support frame 2, a positioning through hole is provided at the bottom of the protective cover 4, a guide rod 5 is fixedly arranged on the outer wall of the protective cover 4, the guide rod 5 is arranged in an arc shape, a dustproof plate 6 is provided on the outer sliding sleeve of the guide rod 5, a winding and pulling mechanism is provided on the outer wall of the dustproof plate 6, a slide groove cooperating with the guide rod 5 to slide is provided at the end of the dustproof plate 6, and a spring 19 is fixedly arranged between the inner wall of the slide groove and the guide rod 5;

[0026] A vertical rod 7 is rotatably penetrated at the top of the support frame 2 , a horizontal plate 8 is fixedly sleeved at the lower end of the vertical rod 7 , a sticky cloth 9 is fixedly provided on the top of the horizontal plate 8 , and the sticky cloth 9 is matched with the lens of the high-definition camera 3 .

[0027] When performing silk screen printing, the position of the diffuser plate can be determined by shooting with the high-definition camera 3, so that the position of the diffuser plate can be accurately adjusted when the diffuser plate enters the interior of the silk screen printer, so that the ink can stably enter the silk screen position, thereby improving the silk screen stability. With the provision of the protective cover 4 and the dustproof plate 6, the high-definition camera 3 can be dust-proofed when the silk screen printing work is interrupted, and dust can be avoided as much as possible from getting on the camera lens and causing a decrease in positioning accuracy. At the same time, when the dustproof plate 6 is away from the positioning through hole, the vertical rod 7 can drive the horizontal rod 8 to rotate, so that the sticky cloth 9 can contaminate the dust on the lens of the high-definition camera 3, thereby further improving the positioning accuracy.

[0028] In order to enable the vertical rod 7 to be driven synchronously while the dustproof plate 6 moves, as shown in FIG. Figure 2As shown, the winding and pulling mechanism includes a cross bar, and the cross bar 10 is rotatably arranged on the outer side of the upper end of the support frame 2. A winding wheel 11 is fixedly sleeved on the rod wall of the cross bar 10, and a pull rope 12 is fixedly wound inside the winding wheel 11. A connecting rod 13 is fixedly arranged at the lower end of the pull rope 12, and the connecting rod 13 is fixedly connected to the outer wall of the dustproof plate 6. A double-headed cylinder 14 is fixedly arranged on the top of the support frame 2, and the ends of the output shafts on both sides of the double-headed cylinder 14 are respectively fixedly arranged with a first rack 15 and a second rack 16, and the first rack 15 and the second rack 16 are respectively meshed with a first gear 17 and a second gear 18, and the first gear 17 and the second gear 18 are respectively fixedly sleeved with the vertical rod 7 and the cross bar 10.

[0029] When it is necessary to use the high-definition camera 3 for pre-positioning before silk-screen printing, the double-headed cylinder 14 is started, so that the first racks 15 and the second racks 16 on both sides move synchronously. At this time, with the cooperation of the second rack 16 and the second gear 18, the cross bar 10 can drive the winding wheel 11 to rotate, so that the winding wheel 11 winds the pull rope 12. At this time, the dustproof plate 6 is pulled and moves along the guide rod 5, and the positioning through hole can be opened. At the same time, under the engagement of the first rack 15 and the first gear 17, the vertical rod 7 is driven to drive the cross plate 8 to rotate, so that the sticky cloth 9 can contact and cooperate with the lens of the camera.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
