Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screen printing, and particularly relates to a screen printing device. Background Art
[0002] Screen printing means pouring ink at one end of a screen printing plate and repeatedly moving a squeegee so that the ink is extruded from the mesh holes of the graphic part onto the substrate. Since the screen plate will gradually wear due to the passage of the ink and the friction of the squeegee during the repeated movement of the squeegee, the screen plate becomes fragile, affecting the printing quality. And during the printing process, the screen plate may encounter various problems, such as clogging, ink leakage, uneven ink application, etc., which affect the screen printing quality. Therefore, the screen printing plate often needs to be replaced regularly to ensure the screen printing quality. However, after replacing the screen printing plate, the position of the screen printing plate may shift compared with the position before replacement, resulting in a shift in the relative position between the screen printing pattern part of the screen printing plate and the substrate, thus reducing the screen printing quality.

[0041] The following refers to Figures 1 to 8 A silk screen printing device according to an embodiment of the present utility model will be described in detail.
[0042] Referring to Figures 1 to 3 , a silk screen printing device according to an embodiment of the present utility model includes a positioning component 100, a silk screen printing component 200, a conveying component 300, a detection component 400, and a calibration component 500. The positioning component 100 is used to position the printing substrate; the silk screen printing component 200 includes a detachably arranged silk screen plate 210, and a silk screen pattern is arranged on the silk screen plate 210; the conveying component 300 is arranged on one side of the silk screen printing component 200 and is used to convey the printing substrate to the positioning component 100; the detection component 400 is arranged on the upper side of the positioning component 100 and is used to detect the positions of the printing substrate and the silk screen pattern located on the positioning component 100; the calibration component 500 is connected to the positioning component 100 and is electrically connected to the detection component 400. The calibration component 500 can adjust the position of the positioning component 100 according to the detection result of the detection component 400, so that the silk screen pattern on the silk screen plate 210 can be accurately aligned with the position to be printed on the printing substrate.
[0043] During the operation of the screen printing device of the present application, first, the printing substrate is conveyed to the positioning assembly 100 by the conveying assembly 300 and positioned on the positioning assembly 100. Then, the detection assembly 400 detects the position of the screen printing pattern portion of the screen printing stencil 210 located above the positioning assembly 100 and the position of the printing substrate located on the positioning assembly 100. Then, with reference to the position of the screen printing pattern portion on the screen printing stencil 210, the calibration assembly 500 adjusts the position of the positioning assembly 100, thereby realizing the adjustment of the position of the printing substrate on the positioning assembly 100, so that the screen printing pattern on the screen printing stencil 210 can be accurately printed on the printing substrate. It can be known from the above operation process that by adjusting the position of the printing substrate on the positioning assembly 100 by the calibration assembly 500, the possibility of the relative position between the screen printing pattern portion on the screen printing stencil 210 and the printing substrate shifting after replacing the screen printing stencil 210 can be reduced, thereby reducing the possibility of the screen printing pattern position on the printing substrate shifting, and further improving the screen printing quality.
[0044] Reference Figure 3 , in some embodiments of the present invention, the calibration assembly 500 includes a horizontally adjusting structure 510 and a rotating structure 520 connected to each other. The horizontally adjusting structure 510 is used to adjust the horizontal position of the printing substrate on the positioning assembly 100, and the rotating structure 520 is used to drive the printing substrate on the positioning assembly 100 to rotate around the vertical axis. It can be understood that after the detection assembly 400 detects the position of the screen printing pattern portion of the screen printing stencil 210 located above the positioning assembly 100 and the position of the printing substrate located on the positioning assembly 100, with reference to the position of the screen printing pattern portion on the screen printing stencil 210, the rotating structure 520 drives the positioning assembly 100 to rotate around the vertical axis to adjust the horizontal attitude of the printing substrate on the positioning assembly 100 to be consistent with the screen printing pattern portion of the screen printing stencil 210. The horizontally adjusting structure 510 drives the positioning assembly 100 to move in the horizontal direction, so that the printing substrate on the positioning assembly 100 is aligned with the screen printing pattern portion of the screen printing stencil 210 in the horizontal direction, so that the screen printing pattern on the screen printing stencil 210 can be accurately printed on the printing substrate.
[0045] Specifically, the rotating structure 520 includes a rotating motor, and the horizontally adjusting structure 510 includes a horizontally adjusting motor. Driven by the horizontally adjusting motor, the positioning assembly 100 can move along the first horizontal direction, thereby adjusting the position of the printing substrate on the positioning assembly 100 in the first horizontal direction.
[0046] It should be noted that screen printing means pouring ink at one end of a screen printing stencil 210, applying a certain pressure to the ink part on the screen printing stencil 210 with a squeegee, and simultaneously moving uniformly towards the other end of the screen printing stencil 210. The ink is extruded from the mesh holes of the screen printing pattern part onto the substrate by the squeegee during the movement, so that the pattern on the screen printing stencil 210 can be printed onto the substrate. During the movement of the squeegee, the position of the substrate may shift.
[0047] Reference Figure 2 , in some embodiments of the present invention, the conveying assembly 300 further includes an adsorption fixture 310 and a conveying line 320. An adsorption structure 311 is provided inside the adsorption fixture 310, and the adsorption structure 311 is used to adsorb the substrate onto the adsorption fixture 310. The conveying line 320 is used to convey the adsorption fixture 310 above the positioning assembly 100. It can be understood that first, the substrate is placed on the adsorption fixture 310, and the substrate is adsorbed on the adsorption fixture 310 through the adsorption structure 311 inside the adsorption fixture 310. Then, the adsorption fixture 310 is conveyed above the positioning assembly 100 through the conveying line 320. Then, screen printing is performed on the substrate on the adsorption fixture 310 through the screen printing stencil 210 located above the positioning assembly 100. Since the substrate is always adsorbed on the adsorption fixture 310 during the screen printing process, the possibility of the substrate shifting during screen printing is reduced, thereby improving the screen printing quality.
[0048] Reference Figure 2 and Figure 3 , in some embodiments of the present invention, the screen printing device further includes a vacuum compensation assembly 600. The vacuum compensation assembly 600 is disposed on the positioning assembly 100 and is used to evacuate the adsorption structure 311 of the adsorption fixture 310 located on the positioning assembly 100 to compensate for the vacuum loss during the conveying process of the adsorption fixture 310.
[0049] It can be understood that during the process of the adsorption fixture 310 carrying the substrate and conveying it onto the positioning assembly 100, the negative pressure in the adsorption structure 311 may be lost, resulting in a decrease in the adsorption force of the adsorption fixture 310 on the substrate. Therefore, when the squeegee moves on the screen printing stencil 210, the position of the substrate may shift, thus affecting the screen printing accuracy.
[0050] In this embodiment, the substrate is adsorbed on the adsorption jig 310. By placing the adsorption jig 310 on the conveyor line 320, the adsorption jig 310 is transported above the positioning assembly 100. Then, the vacuum compensation assembly 600 evacuates the adsorption structure 311 inside the adsorption jig 310 to compensate for the vacuum loss during the transportation of the adsorption jig 310. Subsequently, the screen printing assembly 200 performs screen printing on the substrate on the evacuated adsorption jig 310, reducing the possibility of the substrate shifting during the screen printing process, thereby improving the screen printing accuracy.
[0051] Reference Figure 3 、 Figure 4 And Figure 5 In some embodiments, the vacuum compensation assembly 600 includes a suction cup 610 and a driving structure 620. The suction cup 610 is disposed on the positioning assembly 100 and is used to communicate with the vacuum generator. The driving structure 620 is connected to the positioning assembly 100, and the driving structure 620 can drive the suction cup 610 to approach the adsorption jig 310 so that the suction cup 610 communicates with the adsorption structure 311. It can be understood that the driving structure 620 drives the positioning assembly 100 to approach the adsorption jig 310 located above it, thereby driving the suction cup 610 on the positioning assembly 100 to approach the adsorption jig 310 so that the suction cup 610 communicates with the adsorption structure 311 on the adsorption jig 310. Also, since the suction cup 610 communicates with the vacuum generator, the adsorption structure 311 is evacuated through the suction cup 610, thereby compensating for the vacuum loss during the transportation of the adsorption jig 310, enabling the substrate to be more firmly adsorbed on the adsorption jig 310 during screen printing.
[0052] Specifically, the driving structure 620 is a vertical driving cylinder.
[0053] Reference Figure 4 And Figure 5 In one embodiment, an adsorption surface 312 is formed on the adsorption jig 310. Adsorption holes 311a are provided on the adsorption surface 312. A vacuum chamber 311b is provided inside the adsorption jig 310. The adsorption holes 311a communicate with the vacuum chamber 311b. An air extraction hole 311c communicating with the vacuum chamber 311b is also provided on the adsorption jig 310. A check valve 313 is provided in the air extraction hole 311c. The air extraction hole 311c is used to communicate with the suction cup 610. The vacuum chamber 311b, the adsorption holes 311a, and the air extraction hole 311c together constitute the adsorption structure 311.
[0054] It can be understood that when compensating for the vacuum loss of the adsorption fixture 310 during transportation through the vacuum compensation assembly 600, first, the driving structure 620 drives the suction cup 610 on the positioning assembly 100 to approach the air extraction hole 311c of the adsorption fixture 310, so that the suction cup 610 communicates with the air extraction hole 311c. Then, a negative pressure is applied to the air extraction hole 311c through the suction cup 610, so that the check valve 313 in the air extraction hole 311c is in an open state. At this time, the gas in the vacuum chamber 311b is sucked out of the vacuum chamber 311b through the air extraction hole 311c, so that the negative pressure in the vacuum chamber 311b is enhanced, thereby realizing the evacuation of the vacuum chamber 311b. When the suction cup 610 stops applying negative pressure to the air extraction hole 311c, the check valve 313 is in a closed state, and the outside gas cannot flow into the vacuum chamber 311b through the check valve 313, so that the vacuum degree in the vacuum chamber 311b is maintained in a stable state.
[0055] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the positioning assembly 100 includes a positioning seat 110 and a plurality of positioning blocks 120. The plurality of positioning blocks 120 are respectively arranged on the positioning seat 110. A plurality of positioning holes 314 are arranged on the lower end surface of the adsorption fixture 310. The positioning holes 314 are arranged in one-to-one correspondence with the positioning blocks 120. The suction cup 610 is arranged on the positioning seat 110. The positioning seat 110 is connected to the driving structure 620. The driving structure 620 can drive the positioning seat 110 to approach the adsorption fixture 310, so that the plurality of positioning blocks 120 are respectively inserted into the corresponding positioning holes 314, and the suction cup 610 is communicated with the adsorption structure 311.
[0056] It can be understood that when the adsorption fixture 310 is transported above the positioning assembly 100, the driving structure 620 drives the positioning seat 110 to approach the adsorption fixture 310, thereby driving the plurality of positioning blocks 120 and the suction cup 610 on the positioning seat 110 to approach the lower end surface of the adsorption fixture 310, so that the plurality of positioning blocks 120 are respectively inserted into the plurality of positioning holes 314 located on the lower end surface of the adsorption fixture 310, and the suction cup 610 is communicated with the adsorption structure 311, thereby positioning the adsorption fixture 310 on the positioning seat 110, so that the printing substrate on the adsorption fixture 310 can be positioned on the positioning seat 110.
[0057] In a specific embodiment of the present invention, four positioning blocks 120 are arranged on the positioning seat 110, and four positioning holes 314 adapted to the four positioning blocks 120 are arranged on the adsorption fixture 310.
[0058] Reference Figure 2 、 Figure 3 and Figure 8In some embodiments of the present invention, the screen printing device further includes a pressing assembly 700. The pressing assembly 700 and the suction cup 610 are respectively arranged on opposite sides of the adsorption jig 310. The pressing assembly 700 can press down the adsorption jig 310 so that the adsorption jig 310 and the suction cup 610 are closely attached. It can be understood that the suction cup 610 is driven to move upward by the driving structure 620, so that the suction cup 610 is connected to the adsorption structure 311 located on the adsorption jig 310, and then the substrate on the adsorption jig 310 is pressed down by the pressing assembly 700, so that the suction cup 610 and the lower end of the adsorption jig 310 are more closely attached, thereby reducing the possibility of air leakage between the suction cup 610 and the adsorption structure 311.
[0059] like Figure 1 , Figure 2 and Figure 8 As shown, in a specific embodiment of the utility model, the conveyor line 320 includes two conveyor belts 321 arranged side by side, the two conveyor belts 321 are used to jointly carry the adsorption jig 310, an avoidance gap 320a is formed between the two conveyor belts 321, and the positioning assembly 100 is arranged between the two conveyor belts 321, and the positioning assembly 100 can pass through the avoidance gap 320a; the pressing assembly 700 includes a first driver 710, a second driver 720 and a pressing plate 730, the first driver 710 is connected to the second driver 720, the second driver 720 is connected to the pressing plate 730, the first driver 710 is used to drive the second driver 720 and the pressing plate 730 to move along the first horizontal direction, and the second driver 720 is used to drive the pressing plate 730 to move along the vertical direction.
[0060] It can be understood that the first horizontal direction is the conveying direction of the conveying line 320 .
[0061] It can be understood that the suction cup 610 of the positioning seat 110 is driven by the driving structure 620 to move upward through the avoidance gap 320a, and the adsorption fixture 310 located on the two conveyor belts 321 is lifted off, and then the first driver 710 drives the pressing plate 730 to move above the positioning assembly 100 and make it located above the substrate on the adsorption fixture 310, and then the second driver 720 drives the pressing plate 730 to press down the substrate on the adsorption fixture 310, thereby driving the adsorption fixture 310 to move downward, so that the adsorption fixture 310 is The lower end surface of the jig 310 fits more closely with the suction cup 610, and then the suction structure 311 is evacuated by the suction cup 610 to compensate for the vacuum loss of the adsorption jig 310 during the transportation process; when the vacuum loss in the adsorption structure 311 is compensated, the second driver 720 drives the pressure plate 730 to move up and away from the substrate on the adsorption jig 310, and then the first driver 710 drives the pressure plate 730 to leave the top of the positioning component 100 to avoid interference with the screen printing component 200 when it is working.
[0062] It is understandable that by pushing the adsorption jig 310 away from the two conveyor belts 321 through the driving structure 620 , the force on the pressing area of the conveyor belt 321 when the pressing assembly 700 presses down the adsorption jig 310 can be reduced, thereby increasing the service life of the conveyor belt 321 .
[0063] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the screen printing device further includes a lifting structure 800, which is transmission-connected to the positioning assembly 100, and the lifting structure 800 can drive the positioning assembly 100 to rise, thereby driving the adsorption fixture 310 to rise, so that the substrate on the adsorption fixture 310 reaches a preset height. It can be understood that the positioning assembly 100 is driven upward by the lifting structure 800, thereby driving the adsorption fixture 310 on the positioning assembly 100 to move upward, so that the substrate on the adsorption fixture 310 rises to a preset height, so that each substrate can be screen-printed at the same height, so as to reduce the difference in the screen-printed patterns on each substrate after screen printing, thereby improving the uniformity of the screen-printed patterns on each substrate.
[0064] refer to Figure 3 In a further embodiment of the utility model, the lifting structure 800 is connected to the driving structure 620, and the lifting structure 800 can drive the driving structure 620 to move in the vertical direction. The lifting structure 800 is connected to the rotating structure 520, and the rotating structure 520 can drive the lifting structure 800 to rotate around the vertical axis. It can be understood that when the lifting structure 800 drives the driving structure 620 to move upward, the positioning assembly 100 connected to the driving structure 620 moves upward accordingly, thereby driving the adsorption jig 310 on the positioning assembly 100 to move upward so that the substrate on the adsorption jig 310 reaches a preset height; the lifting structure 800 is driven to rotate around the vertical axis by the rotating structure 520, thereby driving the driving structure 620 connected to the lifting structure 800 to rotate, thereby driving the positioning assembly 100 on the driving structure 620 to rotate, so that the adsorption jig 310 on the positioning assembly 100 rotates around the vertical axis to adjust the horizontal posture of the substrate on the adsorption jig 310; the rotating structure 520 is driven to move in the horizontal direction by the horizontal adjustment structure 510, so as to drive the driving structure 620 on the lifting structure 800 to move in the horizontal direction, thereby driving the positioning assembly 100 connected to the driving structure 620 to move in the horizontal direction, so that the adsorption jig 310 on the positioning assembly 100 moves in the horizontal direction to adjust the horizontal position of the substrate on the positioning assembly 100.
[0065] Specifically, the lifting structure 800 includes a lifting cylinder.
[0066] refer to Figure 2, in some embodiments of the present utility model, the screen printing device further includes a limiting member 900. The limiting member 900 is disposed on the upper side of the positioning assembly 100. The limiting member 900 has a limiting surface at a preset height, and the limiting surface is used to abut against the upper end surface of the adsorption jig 310. It can be understood that by lifting the adsorption jig 310 through the lifting structure 800, when the upper end surface of the adsorption jig 310 abuts against the limiting surface of the limiting member 900, the adsorption jig 310 stops moving upward. At this time, the upper surface of the printing substrate on the adsorption jig 310 reaches the preset height, further ensuring the distance between the printing substrate and the screen printing stencil 210 during printing, thereby ensuring the uniformity of the printed patterns of each printing substrate.
[0067] In a further embodiment of the present utility model, the screen printing device includes four limiting members 900. The four limiting members 900 are respectively arranged on the conveying line 320 and are distributed in a square shape.

It can be understood that by driving the screen printing assembly 200 through the driving assembly 1000, when it is located above one of the positioning assemblies 100, the detection assembly 400 located above this positioning assembly 100 can detect the position of the screen printing pattern part of the screen printing stencil 210, and take the position of the screen printing pattern part on the screen printing stencil 210 as a reference, and then adjust the position of this positioning assembly 100 through the calibration assembly 500, so that the screen printing pattern on the screen printing stencil 210 can be accurately printed on the printing substrate on this positioning assembly 100; by driving the screen printing assembly 200 through the driving assembly 1000 to be located above each positioning assembly 100, and then adjusting the positions of the positioning assemblies 100 by each calibration assembly 500 according to the corresponding detection assemblies 400, so that the screen printing patterns on the screen printing stencil 210 can be accurately printed on the printing substrates on each positioning assembly 100.
[0069] Reference Figure 1 and Figure 7, in a specific embodiment of the present utility model, the driving assembly 1000 includes a horizontally driving structure 1100 and a vertically driving structure 1200 that are connected to each other. The vertically driving structure 1200 is connected to the screen printing assembly 200 and can drive the screen printing assembly 200 to move in the vertical direction. The horizontally driving structure 1100 can drive the vertically driving structure 1200 to move in the second horizontal direction, so that the screen printing assembly 200 can reciprocate above a plurality of positioning assemblies 100. The second horizontal direction is perpendicular to the first horizontal direction.
[0070] It can be understood that the screen printing assembly 200 is positioned above the positioning assembly 100 by the horizontally driving structure 1100, and then the vertically driving structure 1200 is driven to approach the printing substrate on the adsorption fixture 310 located on the positioning assembly 100. Then, the screen printing assembly 200 performs screen printing on the printing substrate.
[0071] Such as Figure 7 and Figure 8 As shown, in some embodiments of the present utility model, the screen printing assembly 200 further includes a mounting frame 220, a third driver 230, and a screen printing structure 240. The screen printing stencil 210 is detachably disposed on the mounting frame 220. A third driver 230 is disposed on the mounting frame 220. The third driver 230 is connected to the screen printing structure 240 and can drive the screen printing structure 240 to move in the first horizontal direction. Among them, the screen printing structure 240 includes a mounting seat 241, a first squeegee 242, a second squeegee 243, a fourth driver 244, and an inkjet module 245. The first squeegee 242, the inkjet module 245, and the second squeegee 243 are sequentially arranged at intervals in the first horizontal direction. The fourth driver 244 is connected to the inkjet module 245 and is used to drive the inkjet module 245 to move in the second horizontal direction. The inkjet module 245 is used to eject ink. A first lifting structure 246 and a second lifting structure 247 are disposed on the mounting seat 241. The first lifting structure 246 is connected to the first squeegee 242 and is used to drive the first squeegee 242 to lift. The second lifting structure 247 is connected to the second squeegee 243 and is used to drive the second squeegee 243 to lift.
[0072] It can be understood that under the drive of the third driver 230, the mounting seat 241 can move in the first horizontal direction; under the drive of the fourth driver 244, the inkjet module 245 can move in the second horizontal direction, so that the ink can be evenly sprayed on the screen printing stencil 210 in the second horizontal direction; under the drive of the first lifting structure 246, the first squeegee 242 can descend and abut against the screen printing stencil 210, or the first squeegee 242 can ascend and leave the screen printing stencil 210; under the drive of the second lifting structure 247, the second squeegee 243 can descend and abut against the screen printing stencil 210, or the second squeegee 243 can ascend and leave the screen printing stencil 210.
