Description of the actions of Tuzhang
A screen printing method of the screen printing apparatus 100 will be described with reference to fig. 4.
Here, an operation of performing printing on the left side after performing printing on the right side will be described.
Initial setting of
The following operations are performed based on an electric signal from the control unit 70.
When the power of the screen printing apparatus 100 is turned on, the screen printing apparatus 100 starts an initial operation and performs initial setting.
Feeding of lime slurry
First, a slurry is supplied to the upper surface of the screen plate 90 by a slurry supply device, not shown.
As shown in fig. 5, the slurry supply means supplies the slurry only between the first blade 10 and the second blade 20.
The slurry supply device supplies the slurry between the first blade 10 and the blade 30 and between the second blade 20 and the blade 30.
There is no slurry present on the outer side of the first blade 10 and the second blade 20.
Further, the slurry may be manually supplied not by the slurry supply device.
Fastening of scraper 30
The squeegee up-down driving section 53 drives the squeegee 30 in the up-down direction, and fixes the position of the squeegee 30 at the set height position T2.
The squeegee up-down driving section 53 is positioned so that the lower end portion 39 of the squeegee 30 is at the same height as the horizontal surface of the screen plate 90 or slightly lower than the horizontal surface of the screen plate 90.
With this positioning, the slurry can be applied to the screen 90 by the movement of the squeegee 30 in the right and left directions.
The control unit 70 sets the head 110 at the left printing start position by the left and right driving unit 60.
Procedure S1 for setting up workpiece
The controller 70 places the workpiece 900 on the printing table 910 by a carrying-in and carrying-out device not shown.
At the same time, the first blade up-and-down driving portion 51 raises the first blade 10 as shown in fig. 5. At this time, the vertical position of the squeegee 30 is maintained in a state of being fixed at the set height position T2.
The second squeegee up-down driving section 52 sets the second squeegee 20 to the printing height position T3 and presses the screen plate 90. At this time, the vertical position of the squeegee 30 is maintained in a state of being fixed at the set height position T2.
Twenty-right printing process S3
The control unit 70 drives the head 110 from the left printing start position to the right by the left/right driving unit 60.
When the head 110 is driven rightward, the squeegee up-down driving section 53 applies the paste by bringing the squeegee 30 into contact with or close to the screen 90 without a gap.
The screen 90 is coated with the slurry between the first doctor blade 10 and the squeegee 30 while the squeegee 30 is held at the set height position T2 in the vertical position.
The second squeegee up-and-down driving unit 52 presses the second squeegee 20 against the screen 90, and the head 110 moves rightward to perform screen printing.
The second blade 20 prints with the paste between the first blade 10 and the squeegee 30.
The control unit 70 moves the head 110 to the right printing end position by the left-right driving unit 60.
Procedure S4 for setting up workpiece
The control unit 70 carries out the workpiece 900 whose printing has been completed by a carrying-in and carrying-out device, not shown, and places a new workpiece 900 on the printing table 910.
As shown in fig. 6, the second blade up-and-down driving portion 52 raises the second blade 20. At this time, the vertical position of the squeegee 30 is maintained in a state of being fixed at the set height position T2.
First doctor lowering step S5
The first squeegee up-down driving section 51 sets the first squeegee 10 at the printing height position T3 and presses the screen plate 90. At this time, the vertical position of the squeegee 30 is maintained in a state of being fixed at the set height position T2.
Left printing process S6
In the case of left-hand printing, the right-hand printing end position is set as the right-hand printing start position in this state, and printing is performed in the reverse operation to that in the case of right-hand printing.
The control unit 70 drives the head 110 from the right printing start position to the left direction by the left-right driving unit 60.
When the head 110 is driven leftward, the squeegee up-down driving section 53 causes the squeegee 30 to contact or approach the screen 90 without a gap, thereby applying the slurry.
The squeegee 30 is held in a state in which the vertical position is fixed at the set height position T2, and the paste between the second squeegee 20 and the squeegee 30 is applied to the screen 90.
The first squeegee up-and-down driving unit 51 presses the first squeegee 10 against the screen 90, and the head 110 moves rightward to perform screen printing.
The first blade 10 prints with the paste between the first blade 10 and the squeegee 30.
The control unit 70 moves the head 110 to the left printing end position by the left-right driving unit 60.
Repeating process
After the completion of the carrying out of the printed workpiece 900, the control unit 70 determines whether or not the next printing is present, and returns to the setting step S2 when the next printing is present.
In the right direction printing, the left side printing end position is set as the left side printing start position in this state, and printing is performed in the reverse operation to that in the right direction printing.
If there is no next printing, the control section 70 ends the printing.
Twining embodiment 1 is characterized
In embodiment 1, a blade is disposed between two blades, and slurry is disposed between the two blades and the blade. Therefore, in any one of the right and left printing, the squeegee is disposed in front of and behind the printing direction.
In the forward printing, one paste is used for blade application and the other paste is used for blade printing, while in the backward printing, the other paste is used for blade application and the other paste is used for blade printing.
Description of effects of mode for carrying out embodiment 1
According to embodiment 1, printing can be performed in both the forward and backward passes, and the printing efficiency is improved.
According to embodiment 1, the print start position of the left print is the same as the print end position of the right print, and the print end position of the left print is the same as the print start position of the right print. Therefore, when switching between the left and right directions, only the left and right blades are moved up and down, and the head 110 does not need to be moved left and right, and the blade 30 does not need to be moved up and down, thereby improving printing efficiency.
Comparative examples
The configuration of embodiment 1 is compared with a configuration in which a squeegee is provided behind a doctor blade and coating is performed in the forward pass and printing is performed in the backward pass.
As described in embodiment 1, when printing is performed by applying only in the forward pass or only in the backward pass, the following characteristics are provided as compared with the case of applying in the forward pass and printing in the backward pass.
1. In embodiment 1, since the application and the printing are performed by one movement, the printing accuracy is improved without drying the paste, as compared with the case where the application is performed in the forward stroke and the printing is performed in the backward stroke.
2. In embodiment 1, the printing direction and the coating direction are the same, but when the coating is performed in the forward pass and the printing is performed in the backward pass, the printing direction and the coating direction are opposite to each other.
3. In embodiment 1, since the slurry is always present between the doctor blade and the squeegee, the printing end position of the forward pass and the printing start position of the backward pass can be made the same, whereas when the coating is performed in the forward pass and the printing is performed in the backward pass, the slurry after printing is located outside the doctor blade, and therefore the squeegee needs to be raised to go over the slurry, which causes unnecessary operation.
4. When the coating is performed in the forward pass and the printing is performed in the backward pass, the blade is located behind the doctor blade, and therefore the blade may affect the plate separation. In embodiment 1, since nothing is present behind the doctor blade, it is possible to provide a relief equivalent to that of ordinary printing.
According to embodiment 1, printing can be performed while coating, rather than performing printing while performing coating for the next printing, so that high-quality printing can be achieved.
Variation of mode for carrying out embodiment 1
(sensor 80)
The screen printing apparatus 100 of fig. 8 includes a sensor 80.
The sensor 80 is a gap detection sensor for measuring the gap between the lower end 39 of the squeegee 30 and the screen 90.
The right sensor 80 measures the distance between the lower end of the right acute angle portion 32 and the screen 90 at the time of right printing, and transmits the measured distance to the controller 70.
The left sensor 80 measures the distance between the lower end of the left acute angle portion 32 and the screen plate 90 at the time of left printing, and transmits the measured distance to the controller 70.
The controller 70 drives the squeegee up-down driver 53 to dynamically adjust the up-down position of the squeegee 30 during printing so that the gap between the lower end 39 of the squeegee 30 and the screen 90 becomes zero.
As shown in fig. 8, since the screen plate 90 is pressed downward by the squeegee during printing, the screen plate 90 is lowered downward at the printing position, and the screen plate 90 is inclined in the left and right directions of the printing position.
The lowering distance of screen 90 during printing depends on the distance between screen 90 and workpiece 900. The inclination angle of the screen 90 during printing changes according to the movement of the printing position.
Therefore, if the position of the squeegee 30 is fixed, the lower end portion 39 of the squeegee 30 may be separated from the screen plate 90.
The sensor 80 measures the distance between the lower end 39 of the squeegee 30 and the screen 90 during movement of the head 110.
The control unit 70 drives the squeegee up-down driving unit 53 to adjust the up-down position of the squeegee 30 in real time while the head 110 is moving.
Therefore, during printing, the lower end portion 39 of the squeegee 30 and the screen plate 90 can be kept in contact with or close to each other at all times.
The vertical position of the squeegee 30 is adjusted to a height position T2 between the height position T1 of the screen 90 and the height position T3 of the workpiece 900.
In the right printing, T2 gradually increases from the left printing start position to the right printing end position.
In the left printing, T2 gradually increases from the right printing start position to the left printing end position.
Variation of mode for carrying out embodiment 1, 2
(two scrapers 30)
The screen printing apparatus 100 of fig. 9 has two squeegees 30.
The two squeegees 30 are set at the set height position T2 at the initial setting.
Since the right squeegee 30 is fixed to the first blade 10, if the first blade up-and-down driving unit 51 sets the right squeegee 30 to the print height position T3, the right squeegee 30 is set to the set height position T2.
The left squeegee 30 is fixed to the second blade 20, so if the second blade up-down driving section 52 sets the left squeegee 30 to the print height position T3, the left squeegee 30 is set to the set height position T2.
In this example, the squeegee up-down driving section 53 is not required.
Variation of mode for carrying out embodiment 1
(printing pressure change printing)
The printing pressure on the left side and the printing pressure on the right side may be changed.
When the left printing pressure and the right printing pressure are changed, the set height position T2 of the squeegee 30 may be changed in accordance with the printing pressures in the workpiece setting steps S1 and S4 of fig. 4. When the printing pressure is high, the set height position T2 of the squeegee 30 may be lowered as compared to when the printing pressure is low.
Variation of mode for carrying out embodiment 1
(overlay printing)
The same workpiece may be printed in a left and right overlapping manner.
When the overlay printing is performed, the same workpiece 900 may be held without replacing the workpiece 900 in the workpiece setting step S4 of fig. 4.
Variation of mode for carrying out embodiment 1, 5
(flexographic printing)
It is also possible to print on a workpiece having a curved surface.
When printing a workpiece having a curved surface, in the right printing step S3 of fig. 4, the control unit 70 may change the printing height position T3 of the first squeegee 10 and the set height position T2 of the squeegee 30 so as to follow the curved surface of the workpiece 900. Similarly, in the left printing step S6 of fig. 4, the controller 70 may change the printing height position T3 of the second squeegee 20 and the set height position T2 of the squeegee 30 so as to follow the curved surface of the workpiece 900.
Even if the shape of the curved surface of the workpiece 900 is left-right different and left-right asymmetric, the controller 70 can calculate the printing height position T3 and the set height position T2 from the shape of the curved surface of the workpiece 900 by storing the shape of the curved surface of the workpiece 900 in the memory in advance.
Alternatively, if the shape of the curved surface of the workpiece 900 is detected by a shape detection sensor, not shown, the controller 70 can calculate the printing height position T3 and the set height position T2 from the shape of the curved surface of the workpiece 900.
Variation of mode for carrying out embodiment 1
(double printing)
As shown in fig. 10, the positions of the first blade 10 and the second blade 20 may be shifted in the width direction.
The printing table 910 may have two in the width direction, and two workpieces 900 may be arranged in the width direction. The printing table 910 is movable up and down or in the width direction, and the workpiece 900 is replaced by a workpiece carrying-in and carrying-out device, not shown.
In the configuration shown in fig. 10, while the workpiece 900 on the upper side of the paper surface in fig. 10 is printed leftward by the first blade 10, the control section 70 drives the printing table 910 and the workpiece carry-in/out device to replace the workpiece 900 on the lower side of the paper surface in fig. 10.
While the workpiece 900 on the lower side of the paper surface in fig. 10 is printed to the right by the second squeegee 20, the control unit 70 drives the printing table 910 and the workpiece carry-in/out device to replace the workpiece 900 on the upper side of the paper surface in fig. 10. That is, the control section 70 performs the workpiece setting of S1 and S4 shown in fig. 4 in the printing of S3 and S6.
According to the configuration shown in fig. 10, no workpiece is required to be set in S1 and S4, and the printing efficiency is improved.
As shown in fig. 10, the positions of the first blade 10 and the second blade 20 in the width direction may be arranged so as not to overlap each other at all in the width direction.
