Description

Technical Field

[0001] The invention relates to the field of circuit board production, and in particular to a vertical printing up and down bidirectional off-grid device. Background Art

[0002] In the process of screen printing, the distance between the screen and the printed matter (hereinafter referred to as the screen distance) is often shortened to obtain a smaller screen deformation during the scraping process, thereby obtaining a higher screen printing accuracy. However, after reducing the screen distance, the screen deformation is reduced, and the rebound force also becomes smaller. Due to the viscosity of the ink, the rebound force of the mesh itself is not enough to separate the screen and the printed matter. At this time, a device (hereinafter referred to as the off-screen device) is needed to lift the screen as the printing scraper advances, so that the screen and the printed matter can be well separated.

[0003] Existing vertical printing systems are all equipped with a screen-off device only above the screen. When leaving the screen from top to bottom, the upper screen and printed matter can separate quickly, thereby obtaining a thinner ink thickness. Since the lower part is far away from the screen-off device, the screen and printed matter separate slowly, thereby obtaining a thicker ink thickness. Moreover, when the upper and lower screens are simultaneously left off the screen, the middle area where the screen and printed matter are most firmly attached is the middle area, which will cause uneven ink thickness of the printed matter.

[0004] Therefore, we made improvements on this and proposed a vertical printing up and down bidirectional off-grid device. Summary of the invention

[0060] Embodiment 3 further optimizes the vertical printing up and down bidirectional off-grid device provided in Embodiment 1 or 2. Specifically, Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, the off-grid fixed rotating mechanism 3 includes four bearing seats 32, and the four bearing seats 32 are fixedly connected to the mounting frame 5. The four bearing seats 32 are each provided with a rotating shaft 31, and one end of the four rotating shafts 31 is each fixedly connected to a guide rail member 34, and the four guide rail members 34 are each provided with a fixing plate 33, and the four fixing plates 33 are respectively fixedly connected to the outer walls on both sides of the two net frames 22.

[0061] Further, such as Fig.11As shown, the off-grid movable rotating mechanism 4 includes a plurality of guide rails 41, and the plurality of guide rails 41 are fixedly connected to the mounting frame 5, and a rotating shaft seat 43 is provided on the plurality of guide rails 41, and a rotating shaft 42 is provided on the plurality of rotating shaft seats 43, and one end of the plurality of rotating shafts 42 is fixedly connected to a guide rail 2 44, and a mounting plate 45 is provided on the plurality of guide rails 24, and the plurality of mounting plates 45 are respectively fixedly connected to the outer walls on both sides of the two net frames 22.

[0062] The off-grid fixed rotating mechanism 3 and the off-grid movable rotating mechanism 4 can enable the off-grid frame assembly 2 to rotate at an angle to cooperate with the off-grid driving assembly 1 to perform off-grid operations.

[0063] The use process of the vertical printing up and down bidirectional off-grid device provided by the present invention is as follows:

[0064] Before going off-grid, the position of the off-grid cleaning module 6 is adjusted by the electric rod 111 so that the cleaning roller 67 contacts the screen 21. At this time, the stepper motor 66 is started, and the stepper motor 66 drives the screw rod 61 to rotate, and the screw rod 61 drives the movable frame 65 to move on the movable guide rail 62 to change the position of the electric telescopic rod 63. After moving to a suitable position, the electric telescopic rod 63 is started, and the height of the adjustment bracket 69 is changed by the electric telescopic rod 63, so that the height of the cleaning point and the cleaning roller 67 changes, so that the cleaning roller 67 moves to the off-grid operation point area, and then the cleaning motor 68 is started, and the cleaning motor 68 can drive the cleaning roller 67 to clean the ink on the surface of the screen 21;

[0065] After cleaning, the adjusting motor 113 is started, and the driving gear 120 is driven to rotate by the adjusting motor 113. Since the driving gear 120 is meshed with the inner gear frame 119, the adjusting motor 113 can drive the connecting frame 123 to move on the limiting guide rod 128, thereby adjusting the position of the mounting frame 114 and the fixed suction cup 125, so that the fixed suction cup 125 is in contact with the off-grid operation point area, and then the negative pressure pump 121 is started, and the negative pressure pump 121 discharges the gas inside the fixed suction cup 125 through the connecting pipe 122, so that the fixed suction cup 125 is adsorbed and fixed to the mesh frame;

[0066] When printing off-grid, the servo motor 11 is started, and the ball screw 12 can be driven to rotate by the servo motor 11, and the driving rod seat 127 can be driven to move by the ball screw 12, so that the driving rod seat 127 can move horizontally along the direction of the linear guide rail 13. At this time, the driving rod seat 127 can drive the connecting rod 14 to operate, and the connecting rod 14 drives the off-grid frame assembly 2 to rotate by an angle through the rotating shaft 31 and the rotating shaft 42 of the off-grid fixed rotating mechanism 3 and the off-grid movable rotating mechanism 4, and the screen 21 is rotated by an angle, so that the upper and lower parts of the screen 21 and the printed matter can be well separated;

[0067] At the same time, when leaving the grid, the driving rod seat 127 can drive the connecting member 15 to move, so that the connecting member 15 pulls the connecting cable 16, and the connecting cable 16 can pull the fixing frame 118, and the fixing frame 118 compresses the telescopic spring rod 117, and as the telescopic spring rod 117 is compressed, the fixing frame 118 will gradually move away from the screen 21, so that the fixed suction cup 125 pulls the middle area of ​​the screen 21, so that the middle area of ​​the screen 21 can be separated from the printed matter;

[0068] After separation, the fixed suction cup 125 is separated from the screen 21, and the electric rod 111 drives the connecting bracket 19 to move and reset, so that the fixed suction cup 125 and the cleaning roller 67 are away from the screen 21, so as to facilitate the subsequent ink printing operation.
