Embodiment mode 2
In embodiment 2, a point different from embodiment 1 will be described.
* Description of the configuration of the screen printing apparatus 100
● Screen printing device 100 (FIGS. 14 and 15)
The configuration of the screen printing apparatus 100 will be described with reference to fig. 14 and 15.
In the screen printing apparatus 100 according to embodiment 2, the printing table 70 rotates, and the base 52 slides.
* Description of operation of screen printing apparatus 100
As shown in fig. 14, the control section 60 rotates the printing table 70 counterclockwise while printing the right recess 993.
By the rotation of the printing table 70, the right recessed portion 993 is raised, and thus the extension of the screen 91 is reduced as compared with the case where the printing table 70 is not rotated.
The control unit 60 rotates the printing table 70 clockwise and lowers the right push-up unit 80 during printing of the right convex portion 992.
The flat portion 991 is printed in the same manner as in fig. 7 of embodiment 1.
As shown in fig. 15, while printing the left convex curved portion 992, the control section 60 rotates the printing table 70 clockwise and slides the pedestal 52 leftward.
When the radius of the arc of the convex curved portion 992 is R and the inner angle is K degrees, the arc length E of the convex curved portion 992 is as follows.
Arc length E = diameter circumference ratio of arc to circumference
= (2 × radius R) × 3.14 × (K degree ÷ 360 degree)
The control unit 60 specifically performs the following control.
(1) The printing table 70 is rotated clockwise by K degrees around the center 999 of the circular arc.
(2) The base 52 is moved in the leftward direction (printing direction) with respect to the housing 51 by the arc length E.
(3) The squeegee 92 is moved to the left direction (printing direction) by the arc length E.
(4) The left push-up portion 80 is not raised.
By the rotation of the printing table 70 for printing the left convex portion 992, the left concave portion 993 rises, and the inclined surface of the left concave portion 993 becomes horizontal.
Since the inclined surface of the left recess 993 is horizontal, the left push-up portion 80 does not need to be raised during printing of the left recess 993.
During printing of the left recessed portion 993, the inclined surface of the left recessed portion 993 is horizontal, so that there is no recess, and extension of the screen 91 due to the presence of the recess does not occur.
In addition, the control unit 60 may rotate the printing table 70 clockwise and slide the base 52 leftward during printing of the right convex portion 992, similarly to the printing of the left convex portion 992. When the rotation angle of the printing table 70 is smaller than the inner angle of the right convex portion 992, the controller 60 determines the sliding amount of the base 52 according to the rotation angle of the printing table 70.
