DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component processing and tape packaging system.

[0002]

2. Description of the Related Art Many electronic components including semiconductor elements such as mini-mold transistors are manufactured at once by using a strip-shaped lead frame. After taking out the electronic components from the lead frame, they are typically transported using a rotary transport mechanism consisting of a rotary table, and during this transport process, measurements such as external dimensions and electrical characteristics, and stamping are required when shipping. 2. Description of the Related Art A system for performing a series of processes and then inserting the same into a packing tape is known.

A system of this type is disclosed in Japanese Patent No. 2667.
Japanese Patent Publication No. 712 discloses that after taking out electronic components one by one from a lead frame, the electronic components are transferred to a plurality of rotary transport mechanisms arranged continuously, and a series of processes are performed.
A system for packaging on tape is disclosed.

On the other hand, the system disclosed in Japanese Patent No. 2531006 discloses a system in which two electronic components are taken out of a lead frame as a set, transferred to a rotary transport mechanism, and a set of two electronic components is taken. After performing a series of processes in units of, the shift mechanism attached to the upper rotary table for the last rotary transport mechanism that is the last rotary transport mechanism for inserting electronic components into the packing tape And a method of transferring electronic components one by one to a rotary transport mechanism for inserting electronic components at the rearmost stage.

[0005] Japanese Patent No. 2531006 also discloses that four packing tapes, which are arranged in parallel with each other and extend in the tangential direction, are provided on the outer periphery of a rotary transport mechanism for inserting electronic components. When inserting an electronic component into the electronic component, a means (typically, a suction nozzle) for holding the electronic component is moved radially outward of the rotary transport mechanism for inserting the electronic component by using a lane change mechanism. It has been proposed to distribute the electronic component to any one of the four packing tapes according to the electrical characteristics of the electronic component.

According to the system disclosed in Japanese Patent No. 2531006, while a plurality of electronic components are transported as a set using a rotary transport mechanism, various measurements for shipping and the like are performed during the transport. Since the processing is performed, there is a potential advantage that the series of processing can be speeded up or made more efficient.

[0007] However, in the system disclosed in Japanese Patent No. 2531006, as described above,
Electronic components are transferred one by one to the last rotary transport mechanism using the shift mechanism attached to the upper rotary transport mechanism for inserting the electronic components into the packing tape. As a result, the section for transferring the electronic components via the shift mechanism becomes a practical bottleneck, which limits the speedup.

Further, in addition to the above-described shift mechanism, a lane change mechanism is provided for distributing electronic components one by one to a plurality of packing tapes arranged in parallel with each other, so that the system is complicated. This potentially increases the frequency of failures, and may involve additional costs for maintenance.

[0009]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an electronic component processing and tape packaging system which can achieve a higher speed than before. It is another object of the present invention to provide an electronic component processing and tape packaging system that can achieve higher speeds than before, while avoiding system complexity and additional maintenance costs. .

In other words, according to the electronic component processing and tape packing system of the present invention, the plurality of rotary transport mechanisms form the same number of electronic components as one set and move from the first rotary transport mechanism to the rearmost rotary transport mechanism. It is transported to the transport mechanism. In the rearmost rotary transport mechanism for supplying the electronic components to the packing tape, the electronic components forming a pair are held in a state of being separated from each other in the radial direction of the rotary transport mechanism, and held in such a state. The plurality of electronic components forming the set are individually released and accommodated in a plurality of packing tapes arranged along the radial direction of the last rotary transport mechanism.

Thus, the same number of electronic components are transported as a set from the beginning to the end of the plurality of continuously arranged rotary transport mechanisms, so that the conventional shift mechanism is not required. In addition, a plurality of packing tapes are arranged at a distance in the circumferential direction of the last rotary transport mechanism, and the packing tape is disposed along the radial direction of the rotary transport mechanism. In order to individually distribute the plurality of electronic components transported as a set by the transport mechanism to each packing tape, a conventional lane change mechanism can be eliminated. Therefore, according to the present invention, it is possible to increase the speed while avoiding complication of the system and occurrence of additional maintenance cost.
