Description

TECHNICAL FIELD The present invention relates to a device for adsorbing a chip component.

Conventional technology The main axis of the mounting machine of the conventional device for picking up chip components is the fourth
It had the structure shown in the figure. That is, in the rotating spindle body 1, a plurality of vacuum nozzles 3 are mounted on the flange 1a of the spindle body 1 via sliding bearings 2.
Is intermittently rotated at a constant angle by an index unit, and a plurality of vacuum nozzles 3 pick up the component 4 and mount the component.

However, it is difficult to detect the degree of vacuum of the nozzle 4 and the suction state of the component 4 when the vacuum nozzle 3 sucks and mounts the component 4 in the structure as described above. There was a problem. This is for the following reason.

That is, even if a detector for detecting the degree of vacuum of the vacuum nozzle 3 and the suction state of the component 4 is attached to the main spindle body 1,
Since it is rotating, it was difficult to send a signal to the outside.

Therefore, the present invention relates to a device for transmitting the signal of a detector mounted on a rotating spindle to the outside.

Means for Solving the Problems And technical means of the present invention for solving the above problems,
A plurality of transmitters for transmitting the signals of a plurality of detectors are mounted on the rotating main shaft, and a receiver for receiving the signals of the transmitter by non-contact or contact with the outside of the main shaft.

Operation The effects of this technical means are as follows. That is, the output signals of the plurality of detectors that detect the state of the vacuum nozzle of the spindle or the adsorbed electronic components are transmitted from the signal transmitter attached to the spindle, and to the receiver fixed outside the spindle. Sent.

As a result, even the detector signal on the rotating spindle can be transmitted to the outside of the spindle.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 5 denotes a main spindle body of a cylindrical mounting machine, and a slide bearing 6 is provided on a flange 5a of the main spindle body 5 to
A plurality of vacuum nozzles 7 are attached so as to be vertically and rotationally movable.

Further, a detector 8 for detecting the degree of vacuum of the vacuum nozzle 7 is attached to the sliding bearing 6, and a transmitter 9 for transmitting a signal of the detector 8 has the same height on the outer circumference of the main spindle body 5. It is fixed at the correct position.

A receiver 10 is attached to the outside of the spindle main body 5 at the same height as the transmitter 9 and at a predetermined distance from the transmitter 9 as shown in FIG. A spindle unit 5 which uses a magnetic coupling method for signal transmission / reception carries out an intermittent rotary motion at a constant angle by an index unit, and a plurality of vacuum nozzles 7 provided on the spindle unit 5 suck components 11 and mount them. To do.

Next, the operation of the configuration of this embodiment will be described.

The second cross-sectional view of the transmitter 9 and the receiver 10 at fixed positions is shown in FIG.
Shown in the figure. The receiver 10 is fixed at the indexing position of the main spindle body 5 when the vacuum nozzle 7 sucks the component 11. Therefore, when each vacuum nozzle 7 repeats suction / mounting of the component 11 while the main spindle body 5 makes intermittent rotation motion, the receiver 10 constantly outputs a detection signal of the degree of vacuum when each vacuum nozzle 7 comes to the suction position. By reading, the suction state of the component can be determined.

In addition, if the receiver 10 is installed at other positions, the degree of vacuum of the vacuum nozzle 7 at each position can be detected.

Further, in this embodiment, the magnetic coupling method is used for transmitting and receiving signals, but an optical communication method may be used instead.

Next, another embodiment of the present invention will be described.

FIG. 3 shows another embodiment. A plurality of vacuum nozzles 14 are vertically rotatably and rotatably mounted on a flange 12a of a cylindrical main body 12 of a mounting machine via sliding bearings 13.

A detector 15 for detecting the degree of vacuum of the vacuum nozzle 14 is attached to the sliding bearing 13, and an output signal from the detector 15 is sent to the signal transmission plate 16. The signal transmission plates 16 of the plurality of vacuum nozzles 14 are fixed at the same height on the outer circumference of the spindle body 12. As shown in FIG. 3, the brush 17 is attached to the outside of the main spindle body 12 in a state of contacting the signal transmission plate 16.

Like the first embodiment, this embodiment is also a component of the vacuum nozzle 14.
The change in the degree of vacuum when adsorbing 18 can be detected.

Further, the detectors 8 and 15 of the first and second embodiments can be applied not only to the detection of the vacuum degree of the vacuum nozzle but also to the transmission of other signals by changing the detectors such as the state detection of the adhesive parts.

As described above, according to the present invention, the rotating main body is provided with the state detector of the nozzle or the suction component and the signal transmitter of the detector, and the receiver for receiving the signal of the transmitter is attached to the outside of the main body. Since it is a device that transmits and receives, it is possible to detect the state of the nozzle on the rotating main shaft or the suction component, and transmit a signal to the outside.
