DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device used for a component mounting device for mounting components such as electronic components on a printed circuit board.

[0002]

2. Description of the Related Art In recent years, the speed of a component mounting apparatus has been increased, and electronic components to be handled have also become smaller. In order to stably supply minute electronic components, the electronic components are sandwiched between a vacuum suction nozzle and a push-up pin to perform a suction operation.

Hereinafter, a conventional component supply device will be described. As shown in FIG. 3, in order to supply the electronic component 11 to the component mounting device, the reel 13 in which the component storage tape 12 storing the component 11 is wound and stored is held by the holding unit 1 of the component supply device 20.
4 and the driving gear 1 via the lever 19.
6, a component supply device 2 that pulls out the component storage tape 12 of the reel 13 and sends out the component 11 stored in the component storage tape 12 to a predetermined component removal position 18 in an intermittent motion.
0 is known. In the figure, reference numeral 15 denotes a clamper for fixing the component supply device 20 to a component mounting device (not shown), and 17 denotes a tape press. As shown in FIGS. 4 and 5, the cover tape 12a is peeled off at a predetermined position before being transported to the component pick-up position 18, and the component 11 of the component storage tape 12 transported to the component pick-up position 18 is a vacuum suction nozzle. The push-up drive block 3 is driven in synchronization with the timing at which the 2 moves down to the component pick-up position 18, and is pushed up by the push-up drive pins 4. At this time, the push-up lever 5 rotates about the rotation support pin 6 to push up the push-up pin 7. The push-up pin 7 breaks the seal 9 and pushes up the part 11, and forcibly presses and sucks the part 11 against the vacuum suction nozzle 2.
The original state is restored by the restoring force of the spring 8.

[0004]

However, in the above-described conventional configuration, as shown in FIG. 6A, the component 11a that was standing when the cover tape 12a was peeled off was moved to the component take-out position 18 while standing. When the vacuum suction nozzle 2 comes down as shown in FIG.
a breaks through the bottom tape 12b and the seal 9, and FIG.
When the component 11b drops into the guide hole 10 as shown in FIG. 3C, the operation of the push-up pin 7 is hindered when the next component 11b is sent to the component removal position 18, so that the component 11b can be sucked by the vacuum suction nozzle 2. However, there is a problem that the sticking rate is reduced, and a crack is generated in the seal 9 due to the repetition of the push-up operation, the sticker 9 is peeled off, hinders the running of the component storage tape 12, resulting in a poor feeding, and a reduced sticking rate. Was.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, in which the suction operation is not hindered by the components sent while standing at the component pick-up position, the suction rate is not reduced, and the component storage tape is not used. It is an object of the present invention to provide a component supply device capable of running smoothly.

[0006]

In order to achieve this object, a component supply device according to the present invention provides a component supply tape which pushes up a component stored in a component storage tape at a component removal position into a guide hole of a push-up pin. A cylindrical cap having a cap hole smaller than the size is provided.

[0007]

According to this configuration, even if a standing component comes to the component removal position, the component is prevented from entering the guide hole, and the component can be stably sucked.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2 showing an embodiment of the present invention, the same parts as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 1, the feature of the present embodiment is that the guide hole 10 of the push-up pin 7 is different from the above-described conventional configuration.
Is that the cap 1 is disposed on the upper part of the. Cap 1
Has a cap hole 1a which is smaller than the size of the component 11 at the tip and has a tip from which the tip of the push-up pin 7 protrudes.

A description will be given of the relationship and operation of each component in the component supply device including the above components.

Descriptions of the same operations as those described in the conventional example will be omitted. As shown in FIG. 2 (a), even if the component 11a comes to the component removal position while standing, and the vacuum suction nozzle 2 descends as shown in FIG. The push-up pin 7 does not enter the guide hole 10 and is sucked up in a standing state without affecting the operation of the push-up pin 7 or is sent as it is, as shown in FIG. As shown in ()), when the component 11b sent next arrives at the component removal position 18, the standing component 11a does not adversely affect the component 11b, and a stable suction operation can be performed. In addition, the cap 1 allows the component 11 to stably and not fall down even when the push-up pin 7 is moved up and down, and the conventional seal 9 is not used, so that the component storage tape 2 can be smoothly fed.

In addition, a component supply device provided with a take-out means having a push-up pin 7 using a guide hole formed by integrally processing the same shape as the above-mentioned cap 1 on the guide hole 10 of the push-up pin 7. Even in this case, the same effect as in the present embodiment can be obtained.

[0014]

As is apparent from the above description of the embodiment, according to the present invention, the guide hole of the push-up pin for pushing up the electronic component stored in the component storage tape at the component pick-up position is smaller than the size of the component at the tip. By providing a cylindrical cap with a cap hole, the suction operation is not hindered by components sent while standing at the component removal position, the suction rate does not decrease, and the running of the component storage tape is smooth. It is possible to realize an excellent component supply device that can perform the above.
