Since electronic parts are attracted to the main body side by magnetic force within the range not restrained from the top surface, the electronic parts can be prevented from jumping out even when there is no shutter when the tape-shaped parts assembly is fed, and the parts accuracy and assembly accuracy are severe. The shutter can be omitted, and the structure of the component supply device can be simplified.

Further, the magnet is divided into a first magnet provided at the component taking-out position and a second magnet provided before the component taking-out position, and the suction nozzle of the electronic component mounting machine is placed at the component taking-out position. Immediately after contacting the upper electronic component, a driving force is applied from the electronic component mounting machine to separate the first magnet from the conveying surface of the main body, and by adopting the take-out method, the electronic component is attracted. It will be even easier.

It is sent to the component take-out position 6 and supplied to the electronic component mounting machine. Here, the tape retainer 7 that holds the tape-shaped component assembly 1 from the upper surface is provided with a peeling portion 10 that separates the cover tape 8. Then, the cover tape 8 is wound by the winding section 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 configurations are the same as the above-mentioned conventional example. A feature of this embodiment is that the magnet 13 is provided on the tape transport surface of the main body 5. FIG. 2 shows an enlarged view of an essential part of the magnet 13, and the magnet 13 is in the 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 from the upper surface to the cover tape 8. It is located in a range that is not suppressed by and sucks the electronic component 4. Therefore, the electronic component 4 does not violate even if various vibrations occur until the electronic component mounting machine picks it up. Further, 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 the essential parts of a component supply device according to another embodiment of the present invention. In FIG. 3, 11 is a first magnet arranged at the component taking-out position 6, 14 is a second magnet arranged 6th before the component taking-out position, and a lever 15 is connected to the first magnet 11. Has been done.

As is apparent from the above description of the embodiments, the present invention places the magnet on the conveying 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 extraction position. Since the electronic components are magnetically attracted and fixed by the magnetic force, and even if the shutter is opened when the components are attracted, it is possible to prevent the electronic components from violating against various vibrations, so that stable supply to the electronic component mounting machine can be realized.

Further, if the magnet is provided on the conveying surface of the main body so as to be located on the back side of the tape-shaped component assembly from the peeling position for separating the cover tape to the component removal position,
Since the cover tape attracts the electronic component to the main body side by magnetic force in a range where the electronic component is not suppressed from the upper surface, it is possible to prevent the electronic component from jumping out even without a shutter when feeding the tape-shaped component assembly. It is possible to omit a shutter having strict component precision and assembly precision, and it is possible to simplify the structure of the component supply device.
