[0009]

The operation of this means for solving the problems is as follows. A magnet is provided on the transport surface of the main body of the component supply device so that it is located on the back side of the tape-shaped component assembly at the component removal position, and the electronic components are attracted and fixed by magnetic force, so when picking up components Even if the shutter is opened, it is possible to prevent the electronic components from being violent against various vibrations.

Further, if the magnet is provided on the transport surface of the main body so as to be located on the back side of the tape-like component assembly from the peeling position where the cover tape is separated to the component take-out position, the cover tape holds the electronic component. Since the electronic components are attracted to the main body side by magnetic force within a range not suppressed from the upper surface, the electronic components can be prevented from jumping out even if there is no shutter at the time of feeding the tape-shaped component assembly, and strict component accuracy and assembly accuracy are required. The shutter can be omitted, and the structure can be simplified as a component supply device.

Further, the magnet is divided into a first magnet provided at the component pick-up position and a second magnet provided before the component pick-up position. Immediately after abutting on the upper electronic component, a driving force is given from the electronic component mounting machine, the first magnet is separated from the transfer surface of the main body, and the take-out method is adopted, so that the electronic component is attracted. It becomes even easier.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a component supply device of the present embodiment. As shown, the electronic component 4 is housed at predetermined intervals in a base tape, and the reel 2 around which the tape-shaped component assembly 1 having the cover tape 8 on the upper surface of the electronic component 4 is held by the holding unit 3 At the same time, the tape-like component assembly 1 is pulled out at a predetermined pitch by a driving force from the electronic component mounting machine via a driving mechanism, and the stored electronic components 4 are moved along a tape conveying surface of the main body 5 at a predetermined pitch. It is sent to the component take-out position 6 and supplied to the electronic component mounting machine. Here, the tape holder 7 for holding the tape-shaped component assembly 1 from the upper surface is provided with a peeling section 10 for separating the cover tape 8. Then, the cover tape 8 is wound by the winding unit 9. Reference numeral 12 in the figure denotes a clamper for fixing the component supply device to the component supply unit of the electronic component mounting machine.

These components are the same as those of the above-described conventional example. This embodiment is characterized in that the magnet 13 is provided on the tape transport surface of the main body 5. FIG. 2 is an enlarged view of a main part of the cover tape 8. The magnet 13 is provided in a range from the peeling portion 10 of the cover tape 8 to the component take-out position 6, that is, the electronic component 4 of the tape-shaped component assembly 1 is covered with the cover tape 8 from the top. The electronic component 4 is located in a range where the electronic component 4 is not suppressed. Therefore, the electronic component 4 does not ramp up even if there are various vibrations until the electronic component mounting machine sucks. Furthermore, even if the shutter does not hold down the electronic component 4, the electronic component 4 does not jump out even when the tape-shaped component assembly 1 is fed.

FIG. 3 is an enlarged view of a main part of a component supply device according to another embodiment of the present invention. In FIG. 3, reference numeral 11 denotes a first magnet disposed at the component extracting position 6, reference numeral 14 denotes a second magnet disposed before the component extracting position 6, and a lever 15 is connected to the first magnet 11. Have been.
Further, an L-shaped drive lever 17 is rotatably provided on the main body 5 by a pin 18, and the lever 15 and the drive lever 1 are provided.
7 is rotatably connected by a connecting portion 16. When the driving force from the electronic component mounting machine is applied to the driving lever 17, the first magnet 11 is separated from the transfer surface of the main body 5. In the drawing, 19 is a spring for returning the first magnet 11 when the driving force is released, 20 is a stopper pin for determining the initial position of the first magnet 11, and 21 is a suction nozzle.

Next, a method of taking out an electronic component using the component supply device of the present embodiment will be described with reference to FIGS. Here, when the suction nozzle 21 of the electronic component mounting machine contacts the electronic component 4 conveyed to the component removal position 6 of the component supply device, when the electronic component mounting machine gives a driving force to the drive lever 17, The first magnet 11 that has magnetically attracted the electronic component 4 at the component extraction position 6 via the connecting portion 16 and the lever 15 is separated from the electronic component 4 as shown in FIG. And the suction nozzle 21 can take out the electronic component 4.

[0016]

As is apparent from the above description of the embodiment, according to the present invention, the magnet is mounted on the conveying surface of the main body of the component supply device so as to be located on the back side of the tape-shaped component assembly at the component removal position. With this arrangement, even when the electronic component is attracted and fixed by the magnetic force and the shutter is opened when the component is sucked, the electronic component can be prevented from being violent against various vibrations, so that a stable supply to the electronic component mounting machine can be realized.

Further, if the magnet is provided on the transport surface of the main body so as to be located on the back side of the tape-like component assembly from the peeling position for separating the cover tape to the component take-out position,
Since the electronic component is attracted to the main body side by magnetic force in a range where the cover tape does not suppress the electronic component from the upper surface, the electronic component can be prevented from jumping out without a shutter when feeding the tape-shaped component assembly, A shutter with strict component accuracy and assembly accuracy can be omitted, and the structure of the component supply device can be simplified.
