Abstract

PURPOSE:To automatically insert a printing wire in the hole of a wire guide, by measuring the position of the hole of the wire guide after a housing is positioned to a lid and moving the first jig in X- and Y-directions on the basis of the data of a measuring device. CONSTITUTION:After a housing 6 is positioned to a lid 29, the positions of all of the holes 25 of a wire guide 8 are measured by a measuring device 32 and the position data thereof is stored in a control apparatus. Next, a wire unit 5 is grasped by a hand 39 and the leading end of a printing wire 1 is allowed to approach a guide 9 to insert the printing wire 1 in a slit 9a. A jig 35 is moved in X- and Y-directions on the basis of the data of the measuring device 32 and the bottom part of a groove 35a is positioned above the first hole 25a and a jig 38 is moved in the Y-direction. When the leading end of a printing wire 1a is allowed to approach the wire guide 8 in this state, the leading end of the printing wire 1a is inserted in the groove 35a. When the jig 38 is moved in the X-direction, the jig 38 presses the printing wire 35a to the bottom part of the groove 35a, and therefore, the positioning of the printing wire 1a to the hole 25a in the X- and Y-directions is completed to insert the printing wire 1a in the hole 25a.

In this state, when the tip of the first printing wire 1a is brought close to the wire guide 8, the tip of the printing wire 1a is inserted into the groove 35a, as shown in FIG. 2(C). In this case, printing wire 1
Even if the position of the tip of a does not match the position of the groove 35a, the tip of the printing wire 1a is guided along the inclined surface 35b, and the tip of the printing wire 1a is inserted into the groove 55a. In this state, as shown in FIG. 2(D), the jig 38
f 1.8 when moved in the X direction.

Since the jig 68 presses the printing wire 1a against the bottom of the groove 55a, the printing wire 1a is moved in the X direction and Y direction relative to the hole 25a.
After the direction positioning is completed, the printing wire 1a is inserted into the hole 25a.
inserted into. Next, as shown in FIG. 3(A), the jig 68 is moved in the Y direction, and the jig 35 is moved in the Y direction to position the bottom of the groove 35a above the second hole 25b. let In this state, when the tip of the second printing wire 1b is brought close to the wire guide 8, the tip of the printing wire 1b is inserted into the groove 35a, as shown in FIG. 3(B). In this state, as shown in FIG. 3(C), the jig 38
' When moved in the iX direction, the jig 68 moves the printing wire 1b
is pressed against the bottom of the groove 35a, the positioning of the printing wire 1b in the X direction and the Y direction with respect to the hole 25bK is completed, and the printing wire 1b is inserted into the hole 2sb. Thereafter, all the printing wires 1 are inserted into the holes 25 in the same manner.

〔Effect of the invention〕

As explained above, in the printing wire insertion device according to the present invention, since the printing wire can be automatically positioned in the X direction and the Y direction with respect to the hole, the printing wire can be automatically positioned in the hole of the wire guide. can be inserted. As described above, the effects of this invention are remarkable.
