[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component assembly and an electronic component supply device applied to component supply in an electronic component mounter.

[0002]

2. Description of the Related Art A component supplying method in an electronic component mounting machine for mounting electronic components on a circuit board includes a tray system in which electronic components are aligned and housed in a tray and supplied, and electronic components are arranged in a line in a stick-shaped guide. There are a stick method and a bulk cassette method in which a large number of electronic components are accommodated and supplied in a cassette container, but a large number of electronic components are arranged and accommodated in a tape-shaped holder in the longitudinal direction, A parts cassette in which cover tapes are arranged on both sides or one side of a holder and a tape-shaped electronic component assembly holding electronic components is wound around a reel, and the electronic component assembly is mounted on a parts cassette as an electronic component supply device. The method is the most widely used. This parts cassette system has the features that the electronic parts assembly is easy to handle, the parts supply operation is highly reliable, and the parts mounting operation can be speeded up.

At the time of component mounting, a parts cassette as an electronic component supply device equipped with such an electronic component assembly is mounted in parallel with a component supply unit of an electronic component mounter, and the component supply unit is moved to a predetermined position. The electronic component supply device holding the electronic components of
The component is picked up by the mounting head at the component pick-up position, transferred to the component mounting position, and the electronic component is mounted on the positioned circuit board. Further, the electronic component supply device is configured to feed the electronic component assembly by one pitch in synchronism with this mounting operation, and feed the next electronic component to the component take-out position.

By the way, it is necessary to mount and replace the electronic component supply device on the component supply part of the electronic component mounter, but the work is complicated and difficult to automate, and the electronic component supply device is also difficult. On the other hand, the work of attaching and detaching the reel of the electronic component assembly is complicated and time-consuming, and automation is difficult. Further, it is necessary to confirm the component type of the electronic component assembly that has been attached / detached and replaced, and as a whole, the reliability in the electronic component supply is reduced.

Therefore, in order to solve this problem in recent years, in order to automate the exchange of electronic parts, Japanese Patent Laid-Open No. 3-176636 has been proposed.
Inventions such as the issue have been made. In addition, in the method of allowing the equipment side to recognize the component type, as shown in FIG. 4, the type of the electronic component mounted on the electronic component supply device 21 is displayed as the component type code displayed on the package 23 of the electronic component assembly 22. Is stored in the electronic component supply device 21 by reading the stored barcode 24 on the equipment side with the attached barcode reader 25 and storing the electronic component assembly 22 installed in the electronic component supply device 21. It also stores the component types (see JP-A-2-292337).

[0006]

However, in any of these methods, if the type of component mounted in the electronic component supply device changes, data input must be redone. Further, even if the stored data does not match the actual part type, it cannot be detected. In addition, since information such as a bar code that indicates the type of electronic component assembly and the number of stored components is generally displayed on the package part of the electronic component assembly, it is necessary to read with a barcode reader. Cannot be performed while the electronic component supply device is mounted on the component supply section of the facility, which requires a considerable amount of time. Further, the remaining number of components mounted on the electronic component supply device, it is necessary to subtract the number of mounting from the time when first mounted on the electronic component supply device,
When the electronic component assembly in use is removed from the electronic component supply device, there is a problem that the remaining number is completely unknown.

In view of the above-mentioned conventional problems, the present invention improves the reliability of component supply to the component supply unit of an electronic component mounter and ensures high productivity, and an electronic component supply. The purpose is to provide a device.

[0008]

In the electronic part assembly of the present invention, a plurality of electronic parts are arranged in the longitudinal direction of the tape-shaped holder, and cover tapes are arranged on both sides or one side of the tape-shaped holder. An electronic component assembly holding electronic components is characterized in that symbols indicating component data such as the types of electronic components held on a cover tape are provided at appropriate intervals.

Further, the electronic component supply apparatus of the present invention has a holding portion capable of holding the electronic component assembly, a guide path for guiding the electronic component assembly from the holding portion to a component take-out position, and a cover on the guide path. It is characterized by comprising a reading means for reading the symbol of the tape and a memory transfer means for storing and transferring the read component data.

[0010]

According to the electronic component assembly of the present invention, since the cover tape arranged on the surface of the tape-shaped holder is provided with the symbol indicating the component data, the electronic component assembly can be installed in the electronic component supply device. It is possible to confirm the component data with the component mounted or mounted on the component supply unit. Also,
Since the symbols are provided at appropriate intervals, the component data can be confirmed even while the electronic component assembly is in use, and the symbol corresponding to the remaining number of electronic components accommodated in the electronic component assembly is provided. Then, the symbol can be used to check the remaining number of electronic components.

According to the electronic component supply apparatus of the present invention,
Since the reading means for reading the symbol provided on the cover tape of the electronic component assembly is provided, it is possible to confirm the component data such as the component type and the remaining number of components at any time during the production operation. Even if the electronic parts to be mounted on the parts supply device are changed, if the parts are directly mounted on the parts supply section without performing the reading work again, the symbols are automatically read according to the sending operation of the electronic parts assembly, and the parts are automatically read. The data can be transferred to the facility side, so that not only the complicated and troublesome work involved in parts replacement can be relieved, but also the reliability of parts replacement is improved.
