indicates a turntable, and this turntable 1
is configured to be intermittently rotated by 90 degrees counterclockwise as shown by arrows in FIG. 1 by a drive mechanism and a stopper mechanism (both not shown). On the upper surface of the turntable 1, work boards 2 are arranged at 90-degree intervals. A work holder is formed on the work board 2 to removably support a wiring board K and a watch display tube P as a component with leads. In this case, the workpiece holder for the timepiece display tube P is provided at a position on the outer periphery of the turntable 1 than the workpiece holder for the wiring board K, as shown in FIG. A plurality of (8 in this case) are set vertically and horizontally. Also,
A correction means (not shown) for extending the lead wire R in a straight line is provided at a location on the work board 2 where the watch display tube is set. For convenience of explanation,
Work board 2 when turntable 1 rotates
The initial position is designated as X ₁ and then counterclockwise as X ₂ , X ₃ , and X ₄ in order. The position _X1 is a worker station where the worker attaches the wiring board K and the clock display tube P to the work board 2 and discharges the completed board.

Further, on the outer periphery of the turntable 1, the above-mentioned X _{2 and}
(The first component inserter main body in the present invention corresponds to the component inserter main body at position _X2 , and the second component inserter main body corresponds to the component inserter main body at position _X4 ). Both parts insertion machine bodies 5 and 6 basically have the same configuration, and are supported by an XY table 7 that is movable in mutually orthogonal directions and the tip of an arm extending from the XY table 7 so as to be able to rise and fall. A hand 8 and a work board 1 facing the hand 8.
It consists of a clinch head 9 placed below the clinch head. A component feeder 10 is installed in the component insertion machine main body 5 on the upstream side with respect to the rotation direction of the turntable 1.
A plurality of watch display tube pedestals I (DIP ICs) are loaded into this parts supply machine 10.

This component insertion device also determines whether or not the first component, that is, the pedestal I, is individually properly set on the wiring board K at X ₁ , and then inserts the downstream component insertion machine main body at the X ₃ position based on that judgment. A control device for determining whether or not to perform the insertion operation of the watch display tube P according to step 6 is incorporated. The control device includes a detection sensor that detects whether the pedestal I is set normally, and a control device that determines whether or not to operate the component insertion machine 6 on the downstream side based on a signal emitted from the detection sensor. has been done. Note that the details of this control device will be made clearer in the explanation of the operation described later.

Next, the operation of the component insertion device configured as above will be explained. First, a worker stands facing the _X1 position, sets the wiring board K and a plurality of clock display tubes P on the work board 1, and presses a start button (not shown). Then, the turntable 1 rotates 90 degrees counterclockwise as shown by the arrow in FIG. 1 and stops.

When the turntable 1 has completely stopped, the hand 8 of the component insertion device main body 5 grabs the pedestal I that has been set in advance on the component feeder 10 at the _X2 position, and while its movement is controlled by the XY table 7, the wiring Insert them one by one into the desired positions on the board K,
Then, the clinch head 9 performs a clinch process. The insertion order of the pedestal I is predetermined, and is performed in order from 1 to 8 in FIG.

Here, the operation of the operation control device incorporated in the component insertion device will be explained with reference to FIG.

S ₁ ; Activate the component insertion machine main body 5.

S ₂ ; The detection sensor determines whether the pedestal I is set normally.

S ₃₁ ; When the judgment in S ₂ above is YES, "0" is generated.

S ₃₂ ; When the judgment in S ₂ above is NO, "1" is generated.

S ₄ : Shift the shift register WR1 by 1 to the left every time the above-mentioned "0" or "1" is determined.

S ₅ ; Determine whether component insertion is complete or not, and select YES
Proceed to the next step with this condition. If NO, the process returns to step _S1 described above.

While inserting the pedestal I at the _X2 position, the operator simultaneously sets a new wiring board K and a display tube P on the work board 2 at the _X1 position.

When the inserting operation of the pedestal I by the component inserter main body 5 and the work by the operator are completed, the turntable 1 is rotated 90 degrees. Furthermore, each time the turntable 1 rotates, the information in the shift register is transferred to another shift register prepared in advance (WR1→
WR2, WR2→WR3).

In this state, the operator newly sets the wiring board K and display tube P on the work board 2 at the _X1 position, and the component inserter main body 5 places the pedestal I on the wiring board K at the _X2 position. Insert set.

After the above operation is completed, turntable 1
rotates 90 degrees. When the turntable 1 has completely stopped, the hand 8 of the component insertion device main body 6 grabs the display tube P, which has been set in advance on the workboard 2 at the _X4 position, and while its movement is controlled by the XY table 7, They are inserted one by one onto the pedestal I set on the wiring board K, and then clinched by the clinch head 9.

Here, the operation of the control device incorporated in the component insertion device will be explained.

S ₆ ; The transferred shift register WR3 is shifted to the right by 1 (here, it is moved from H to A, contrary to the above-mentioned 1 to 8).

S ₇ ; Determine whether the point at that time is "0" or "1".

When the above judgment is "1", the insertion operation of the display tube P by the component inserter 6 is passed.

S ₈ ; When the above judgment is "0", operate the component inserter 6 to insert the display tube P onto the pedestal I.

S ₉ ; Determine whether component insertion is complete or not, and select YES
Complete the operation subject to the condition. If NO, proceed to the next step.

S ₁₀ ; Return to step S ₆ again.

In this case, while inserting the watch display tube P at the turntable _X4 position, the operator inserts a new wiring board K onto the work board 2 at the _X1 position.
and the display tube P, and at the _X2 position, the component inserter main body 5 inserts the pedestal I.

The above-described operation completes the insertion of the watch display tube P into the wiring board. Then turntable 1
is further rotated 90 degrees, and at the _X1 position, the operator removes the completed wiring board, simultaneously sets a new wiring board K and display tube P on the work board 2, and performs the same operations as described above.

By repeating the above operations, automatic insertion of the watch display tube P into the wiring board K can be realized.

In the above-mentioned component insertion, since the fragile watch display tubes P are individually set on the work board 2, when they are grabbed by the component inserter body and set on the wiring board K, the components do not touch each other. do not collide with each other and there is no risk of them being damaged.

Further, even if the lead wire R of the watch display tube P is bent from the beginning or when inserted into the work board, the work board is provided with a lead wire straightening means, and the lead wire straightening means can be used to straighten the lead wire. The lead wire R can be immediately extended, and even if the lead wire is easily bent, it is possible to reduce insertion errors when inserting it into the pedestal I in a subsequent process.

In the above embodiment, the insertion of the component P into the work board and the attachment and detachment of the wiring board are performed manually, but complete automation can be achieved by automating these operations. Further, the present invention is not limited to the insertion of a watch display tube, but can of course be applied to the insertion of other multi-stage insertion type electronic components.

Further, in the above embodiment, a turntable is used as the conveying means, but this conveying device may be of a straight line type.

Further, in the above embodiment, the work board 2 is placed on the conveyance path, and both the board K and the component P are placed on the top of the work board 2, but only the part P is placed on this work board 2, and the same work board 2 may be arranged at a location other than the conveyance path.

Furthermore, the parts to be inserted by the first insertion machine main body 5 may be supplied on the work board 2 in advance, or may be supplied from another supply machine.

"Effects of the Invention" As explained above, the component insertion device of the present invention can provide the following effects.

(1) A work holder for the board and a work holder for the leaded component are provided on the work board, the leaded component is supported near the board in advance, and the component is inserted into the second component. Since the parts are gripped by the machine body and mounted on the pedestal, workers can handle parts with easily bendable leads more carefully than when parts are supplied by a parts feeder, etc. Deformation is less likely to occur, and insertion errors can be prevented, thereby improving productivity and quality.

(2) The pedestal, which is a hard part, is continuously inserted by a first component insertion machine body having a component feeder, and a series of operations such as mounting the pedestal and mounting leaded components on it are performed. This is done continuously while rotating the turntable.
Efficient production can be achieved with a single worker for mounting and discharging the substrates, etc.
