BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A preferred embodiment of the present invention will be described in detail. FIG. 1 is a perspective view showing a schematic configuration of a tape winding device 10 according to one embodiment of the present invention, and FIG. 2 is an enlarged perspective view showing the tape winding device 10 of FIG.

With reference to these drawings, a tape winding device 10 according to the illustrated embodiment is arranged in front of a wiring board 2 along a transport path ph of the wiring board 2 transported by an endless conveyor 1. It is attached. The endless conveyor 1 itself is well-known, and the driving force of the motor 3 is transmitted by the power transmission mechanism 4 so that the wiring board 2 can be intermittently or continuously conveyed at a predetermined variable speed. It has become.

The wiring board 2 includes a caster 2 a and a leg 2.
b, and the outer side of the conveyor 1 is inclined in a downwardly inclined posture. A wiring tool 2c is provided upright on the wiring board 2. By arranging electric wires along the wiring tool 2c, the wire assembly WA is wired in a predetermined form. ing. The tape winding device 10 includes a table 11 installed at a position opposing the wiring board 2 at a predetermined position,
A single-axis robot 12 that is disposed on the robot and extends in a direction orthogonal to the transport path ph of the wiring board 2;
And a taping head 20 that can be reciprocated in the longitudinal direction of the single-axis robot 12 by being placed on the slide portion 12a.

Referring to FIG. 2, the taping head 2
Numeral 0 has a rotating plate 22 in which a U-shaped guide concave portion 21 is partitioned, a stepping motor 23 for rotating the rotating plate 22, and a tape holder 24 attached to the rotating plate 22. , Stepping motor 23
By rotating the rotary plate 22, the feeding piece T1 of the adhesive tape T carried on the tape holder 24 is rotated.
Can be circulated around the wire assembly WA as a workpiece to perform taping. The stepping motor 23 can stop the rotating plate 22 precisely in the same phase in a predetermined posture shown in FIGS. 1 and 2 similarly to the known structure.

FIG. 3 is a schematic side view schematically showing a main part according to the embodiment of FIG. 1 and 2 and 3
In the stop phase of the taping head 20, a suction nozzle N is disposed behind the feeding piece T1 of the fed tape T, and the negative pressure air forming device 2
5 (only shown in FIG. 1). Then, the feeding piece T by the negative pressure air forming device 25 is used.
By sucking 1 at a predetermined timing described later,
The tension can be applied to the feeding piece T1.

The nozzle N is mounted on a mounting member 26 fixed to the housing portion 20A of the taping head 20 to open along the one diameter direction of the rotating plate 22. Further, a slide cutter 28 is attached to the attachment member 26 via an actuator 27. By reciprocating the slide cutter 28 along the direction of the sine of the rotating plate 22, tension is applied by the nozzle N. The applied piece T1 of the applied tape T can be cut.

A limit switch SW1 is attached to the table 11 via a projection 14 on the upstream side of the transport path ph. The limit switch SW1 is arranged so as to be connected by a dog switch 2e attached to the wiring board 2, and the connection by the dog switch 2e causes the wiring board 2 to move to a predetermined taping position (in the illustrated embodiment). Thus, it is possible to detect that the wiring board 2 has approached the tape winding device 10 (a position orthogonal to the transport path ph).

Referring to FIG. 1, limit switch SW1
Are electrically connected to the sequencer 30. The sequencer 30 is composed of a microcomputer and other electrical components, and drives the single-axis robot 12 by connecting the limit switch SW1 to the taping head 20 in a pre-programmed sequence as described later.
Can be displaced between the release posture shown in FIG. 1 and the working posture shown in FIG.

Further, in the illustrated embodiment, the sequencer 30 is electrically connected to the rotary encoder 5 attached to the power transmission mechanism 4 of the above-described conveyor 1, and the rotary encoder 5 detects the signal. The transport speed of the wiring board 2 can be measured based on the value. In addition, the stepping motor 23 of the taping head 20 is connected to the sequencer 30. By adjusting the rotation speed of the stepping motor 23 by the sequencer 30, the rotation speed of the rotary plate 22 and the taping speed thereby can be reduced. Adjustments can be made.

According to the above construction, when the wiring board 2 is conveyed by the conveyor 1 provided with the tape winding device 10 and approaches a predetermined taping position, the limit switch SW1 as a position detecting means detects this. I do. Next, the sequencer 30 as head control means drives the single-axis robot 12 to displace the taping head 20 in the released posture to the working posture. At this time, the negative pressure air acts from the nozzle N, and the sequencer 30 operates the negative pressure air forming device 25 so that the tension shown by the two-dot chain line in FIG. Of the solenoid valve 25a is controlled. The taping head 20 is displaced from the released position to the working position in a state where the tension is applied to the feeding piece T1, and the guide recess 2
1, the feeding piece T1 is automatically moved to the wire assembly WA by introducing the wire assembly WA into the wire assembly WA.
Will be stuck to the outer peripheral surface of.

After the sticking operation is completed, the sequencer 3
In the case of 0, the solenoid valve 25a of the negative pressure air forming device 25 is closed again to release the negative pressure air. Next, when the stepping motor 23 as a rotating plate driving mechanism rotates the rotating plate 22, the taping operation is started while the wiring plate 2 is moving. At this time, the sequencer 30 as the speed adjusting means adjusts the rotation speed of the rotary plate 22 by the motor 23 as the rotary plate driving mechanism in accordance with the transport speed of the wiring plate 2 detected by the rotary encoder 5. The tape T wound around the wire assembly WA is wound at a desired winding pitch.

As a result, in the illustrated embodiment, since the taping operation can be performed while moving the wiring board 2, the taping operation can be performed without reducing the operation efficiency. When the winding operation is completed, the sequencer 30 opens the solenoid valve 25a again to apply the negative pressure air from the nozzle N to apply tension to the delivery piece T1. In this state, the tape T is cut out by projecting the slide cutter 28 so that the attached tape T is automatically cut off.

Thereafter, by returning each part to the original home position shown in FIG. 1, it is possible to perform taping work without stopping the wiring board 2 at all. The above-described embodiment is merely an example of a preferred specific example of the present invention, and the present invention is not limited to the above-described embodiment. For example, pressurized air may be employed instead of or in combination with the application of tension to the tape T by negative pressure air. Alternatively, tension can be applied to the tape T by employing a mechanical manipulator.

It goes without saying that various modifications are possible within the scope of the claims of the present invention.

[0025]

As described above, according to the present invention,
Since the taping operation can be performed while moving the wiring board, the taping can be performed without reducing the operation efficiency, and a remarkable effect that the unmanned operation can be performed as much as possible is achieved.
