(4) Taping component storage and supply device In order to selectively supply various taping components to the insertion slot 47, a taping component storage and supply device is installed behind the XYθ table. That is, at the lower rear of the XYθ table A, an upper guide rail 78 and a lower guide rail 79 extend parallel to each other in the left-right direction above and below the support fitting 77 fixed to the base frame 1 (both are shown in FIG. 2). The upper guide rail 78 is slidably supported by the lateral movement frame 80, and the guide roller 81, which is pivotally supported by the lateral movement frame 80, is supported by the lower guide rail 79. By rotating a feed screw 84 via a toothed belt 83 by an NC-controlled servo motor 82 (FIG. 4), the lateral movement frame 80 is guided and moved left and right.

A large number of partition plates 86 are attached to the storage surface 85 attached to the lateral motion frame 80, and a large number of electronic components are wrapped around the partition plates 86 by taping, or the rules 87 are removably supported in parallel. A taped and folded carton 87a (Fig. 4) is placed between the partition plates 86 on the storage surface 8.

The axial lead component supply device 90a, the radial lead component supply device 90r, and the storage surface 85 can be moved along the entire length of the base frame 1 from side to side together with the mounting plate 89, and when selectively supplying taping components, the electronic Parts supply device 90a or 90r7! The movement is controlled according to the setting program so that it stops behind l<single fixed position O.

In order to pull out the taping parts from the reel 87 etc., the cam 4

The lever 94 is engaged with either one of the two levers 93 by an engagement/disengagement device that is switched by a control signal depending on whether the electronic component to be selectively supplied to the rod 47 for insertion is an axial lead component or a radial lead component. and oscillate.

However, when the electronic component to be selectively supplied is a stick-packed IC to be described later, it does not engage with any of the levers 93.

The lower end of the lever 94 is connected to the tape feed drive shaft 95, and when engaged, the lever is advanced, and the taped electronic component stopped directly below is advanced by one piece, cutting one cutting edge electronic component. Take it and feed it to Sodo 47 for insertion.

For example, if the electronic component is an axial lead component, the axial lead component is supplied to the insertion head 47 by the advancement of the supply device 90a.

A rotating cam 96 is further provided coaxially with the cam 45 (Fig. 2),
The cam follower 97a contacts this and swings the lever 97 having the fulcrum shaft 92. The lower part of the lever 97 overlaps the lever 94 in FIG.

is slid perpendicular to the plane of the paper in FIG. 3 (see FIG. 3a), thereby rotating the spline shaft 101.

The spline shaft 101 is connected to the radial reed parts supply device 90
It supports an intermediate supply device 102 that receives radial reed parts from r and supplies them to the insertion head 47. In FIG. 3a, the spline shaft 101 is moved up and down by an air cylinder (not shown), a toothed pulley 103 is fixed to the lower part, and a rotatable frame 104 is attached to the base frame 1. A camshaft 105 that is helved driven by a toothed pulley 103 and a concentric center shaft 106 inside the camshaft 105 are provided in the frame 10, 1.

It is caused to fall into the recess 111 provided in 7. In this state, the camshaft 105 and the center shaft 106 rotate together. However, when the camshaft 105 rotates to a position where the chuck member 108 transfers and receives electronic components between the radial lead component supply device 90r and the insertion rod 47, the center shaft 106 stops rotating as the stopper member 112 hits a stopper (not shown). (2) When the camshaft 105 is stopped and further rotated approximately 20 degrees, the roller 110 is pushed out from the recess 111 and the chuck member 108 is pushed out.
is moved forward to open the chuck, and the electronic components are transferred.

A description of the chuck opening/closing mechanism will be omitted here.

When inserting an axial lead component, the intermediate supply device 102 is retracted to the raised position shown by the solid line in FIG. 3 so as not to impede the advancement of the axial lead component supply device 90a. However, when inserting a radial lead component, the intermediate supply device 102 is lowered to the position indicated by the chain line in FIG. 3, and the cam shaft 105 is rotated 180 degrees. After receiving, the rotary shaft 105 is reversely rotated by 180 degrees to supply the radial lead component to the insertion head 47, after which the intermediate supply device 102 is raised.

The raising and lowering of the spline shaft 101 is performed according to a program that selectively supplies radial lead parts.
The timing of rotation of 01 and actuation of chuck member 108 is determined by cam 96.

The air cylinder 113 supplements the cutting and bending force of the lead wires of the axial lead parts by rotating a metal fitting 115 pivotally supported on the base frame I by a pin 114 and pushing down the lever 44. This is a rotary encoder that rotates in synchronization with the cam 45 and issues necessary control signals.

The ICs selectively discharged from the lower end (the lowest stick when a plurality of ICs are stored in the vertical direction) are fed onto the conveyor 120 through the guide tube 119 while changing their posture. The ICs on the conveyor 120 are moved down the chute 121 and further corrected in posture and other aspects by a known additional function device 122, stopped at a waiting position at the exit of the chute, and are then supplied to the insertion head 47. - The XYθ table A, the taping component storage and supply device D, and the stain component storage and supply device E described above are centrally controlled by an NC device provided inside the base frame 1. The NC device includes a part that performs fixed sequence control for 1st general input, positioning, and 1ift output to the XYθ Q and pull A of the printed wiring board P, and a storage and supply unit for the types of electronic components to be inserted. The device, the operation of E, the selection of the insertion spindle and clinch spindle to be used, and the variableness of performing the insertion work by hyper-moving the insertion site of the printed wiring board P to a single fixed position 0 for the selected electronic component. There is also a part that performs program control.

From there, it is fed onto the XYθ table A, where it is positioned and locked. Next, the electronic components to be inserted into the printed wiring board P are taken out one by one from the storage/supply device or E in a predetermined order, and the insertion spindle 3 for inserting the electronic components is taken out one by one in accordance with a predetermined order.
The spindle frame B and the clinch turret C are indexed and rotated by the motor 36 so that the clinch spindle 59 and the clinch spindle 59 are at a single fixed position O, and the ejected electronic component is supplied to the insertion head 47. On the other hand, XYθ table A is
