Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material input positioning device for a screen printing machine that automatically positions and inputs materials into a printed circuit board screen printing machine.

Feeding materials into traditional printed circuit board screen printing machine,
The positioning method is shown in FIG. An operator picks up the material 2 that is conveyed one by one on the conveyor 1 in the pre-screen printing process and places it on the suction cup 4 of the screen printing machine 3.
Thereafter, as shown in FIG. 2, the worker abuts the material 2 against the positioning stopper 5 at a predetermined position protruding from the suction cup 4 to position the material as shown in FIG. After the positioning of the material 2 is completed, by pressing the start button 6 of the printing machine 3, air is sucked through the small hole in the suction cup 4, and the material 2 is attracted to the suction cup 41, and the suction cup 4 is placed inside the printing machine 3. Incoming printing is performed.
According to the conventional method described above, the operator must perform all the positioning of materials to be introduced into the screen printing machine, which has the drawback that the printing work cannot be automated. The purpose of the present invention is to eliminate the drawbacks of the conventional methods, to temporarily position the materials being conveyed one by one on a conveyor, suck them up, automatically feed them into a screen printing machine, and then place them at a predetermined position. An object of the present invention is to provide a material input positioning device for a screen printing machine that makes it possible to automate printing work by positioning the material.

That is, the characteristics of the present invention are that the materials being conveyed one by one on the conveyor are tentatively determined, and the materials are adsorbed and
This makes it possible to automatically feed the material into the screen printing machine and then position it at a predetermined position, thereby automating the printing work.

The present invention will be explained in more detail below according to embodiments shown in the drawings.

FIG. 4 shows an embodiment of a material input positioning device for a screen printing machine that automatically positions the input of materials into a printed circuit board screen printer. That is, the device 7 temporarily positions the materials 2 that are conveyed one by one on the conveyor 1, and the loading device 8 sucks the temporarily positioned materials 2 and inputs them into the printing machine. The number of arms that adsorb the material 2 is 9. In addition, the feeding device 8 allows the printing machine 3 to
A positioning pin 10 is used to abut the material 2 placed on the suction cup 4 against the material positioning stopper 5 located at a predetermined position on the suction cup 4. As described above, the material input positioning device to the screen printing machine 3 is the temporary positioning device 7.
, a material feeding device 8, and a positioning pin 10 provided on the suction cup of the printing press 3. The operation of positioning the material 2 into the printing press 3 by the material input positioning device will be described. In FIG. 5, the material 2 being conveyed one by one on the conveyor 1 is rotated by a motor 12, a belt 13 and a pulley 14 at the same height as the top surface of the conveyor 1 and in the same direction as the conveyance direction of the material 2. Transferred to the conveyor 11.The material 2 transferred to the conveyor 11 moves forward and stops at the stopper 15.
This corresponds to the limit switch 15 installed on the Next, the conveyor 11 stops its rotation in response to the detection signal from the limit switch 15, and at the same time the cylinder 18 is activated to move the width shifting pin 17 in the direction of the material 2, causing the material 2 on the conveyor 11 to hit the stopper 16. guess. Further, when it is detected that the cylinder turtle 8 is activated, the cylinder 20 is activated, the width shifting pin 19 is moved in the direction of the stopper 21, and the material 2 is brought into contact with the stopper 21, thereby completing the temporary positioning of the material 2. The positions of the stoppers 16 and 21 are as shown in FIG.
It is set in advance so that when it is thrown in, it is thrown in at a position about three sides away from the stopper 5 on the suction cup.
When the temporary positioning of the material 2 by the temporary positioning device 7 is completed, the charging operation is then started. The closing operation will be explained using FIG. 6. The plate 2 fixed to the tip of the arm 9 of the feeding device 8 holds the material that is stationary on the conveyor 11 of the temporary positioning device 7 and in contact with the stoppers 16 and 21.
A plate 24 to which a rod of a cylinder 23 fixed perpendicularly to the tip of the cylinder 2 is attached is lowered by the cylinder 23.
When the suction cups 25 attached to both ends of the plate 24 adsorb the material on the conveyor 11, the plate 24 is raised by the cylinder 23 and the material 2 is separated from the conveyor 11. When the material 2 leaves the conveyor 11, the piece 26 to which the rod of the cylinder 28 is attached moves the arm 9 along the guide rail 27 toward the printing machine by the advancement of the rod of the cylinder 28. Next, the positioning operation of the material on the printing machine will be explained with reference to FIG. When the arm 9 reaches the top of the suction cup 4 of the printing machine 3, the material 2 attracted to the tip of the arm 9 of the material feeding device 8 is lowered onto the suction cup, and the material 2 is separated from the suction cup at the tip of the arm 9. Get on top of suction cup 4. FIG. 7 shows a state in which the material 2 is placed on the suction cup 4. When it is confirmed that the state shown in FIG. 7 has been reached, the positioning pin 0 starts the positioning operation. In other words, as shown in FIG.
By advancing the rod of the cylinder 29, the material 2 is pushed onto the suction cup 4, and the material 2 is brought into contact with the positioning stopper 5 on the suction cup 4 shown in FIG. 7, and the positioning in the front, rear, left and right directions is completed. Thereafter, the material 2 is attracted to the suction cup 4 by sucking air through a small hole provided in the suction cup 4, and the suction cup 4 moves forward into the printing machine 3 to perform printing. Although the external dimensions of the material 2 vary depending on the size of the pattern printed thereon, by using the positioning pin 10 having the structure shown in FIG. 9, it is possible to completely abut the positioning stopper 5 of the suction cup 4. can. Locating pin 1 using Fig. 9
The structure of 0 will be explained. The pin 30 is fixed loosely enough to rotate to a rotating shaft mounting plate 33 fixed to the bridge 32.
The tip is fixed to the tip of the rod of the cylinder 29.
The piece 32 is fitted into the outer piece 31 so as to be slidable in the direction of the arrow, and can be fixed to the outer piece 31 by screwing a screw into a screw hole 34 provided in the piece 32. As described above, according to the present invention, in the input positioning device for inputting and positioning materials to a screen printing machine for printed circuit board screen printing, one
It has the effect of automating the printing work by positioning the material being conveyed sheet by sheet, sucking it up and automatically feeding it into the screen printing machine, and then positioning the material at the predetermined position. .
