Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic component processing and tape packaging system.
[0002]
[Prior art]
Electronic components including semiconductor elements such as mini-mold transistors are manufactured in a lump using a strip-shaped lead frame, and the electronic components from the lead frame are shipped separately. After taking out the parts, they are typically transported using a rotary transport mechanism consisting of a rotary table, and in this transport process, a series of processing required for shipping such as measurement of external dimensions and electrical characteristics, and stamping are performed. A system for inserting into a packaging tape after doing so is known.
[0003]
Regarding this type of system, Japanese Patent No. 2667712 discloses that electronic components are taken out one by one from a lead frame and then transferred to a plurality of continuously arranged rotary transport mechanisms to perform a series of processing. After that, a system for packing on a tape is disclosed.
[0004]
On the other hand, in the system disclosed in Japanese Patent No. 2531006, two electronic components are taken out as a set from the lead frame and transferred to the rotary transport mechanism, and the set of two electronic components is used as a unit. After performing a series of processing, a shift mechanism attached to the upper rotary table is used for the rotary transport mechanism at the rearmost stage for inserting the electronic component as the last rotary transport mechanism into the packing tape. A technique is employed in which electronic components are transferred one by one to the most downstream electronic component insertion rotary transport mechanism.
[0005]
Japanese Patent No. 2531006 also discloses that four packaging tapes extending in the tangential direction and arranged in parallel to each other are prepared on the outer periphery of a rotary transport mechanism for inserting electronic components. When inserting the electronic component, the means for holding the electronic component (typically the suction nozzle) is moved radially outward of the electronic component inserting rotary transport mechanism by using the lane change mechanism. It has been proposed to distribute electronic components to any one of four packing tapes according to electrical characteristics.
[0006]
According to the system disclosed in Japanese Patent No. 2531006, a plurality of electronic components are transported as a set using a rotary transport mechanism, and various measurements and processes for shipping are performed on the way. For this reason, this series of processing has the potential advantage of being able to increase the speed or efficiency.
[0007]
However, in the system disclosed in Japanese Patent No. 2531006, as described above, the rotary transport mechanism at the upper stage relative to the rotary transport mechanism at the rearmost stage for inserting the electronic component into the packing tape is used. Since the electronic parts are transferred one by one to the last-stage rotary transport mechanism using the shift mechanism attached to the electronic device, a section for transferring electronic parts through this shift mechanism is actually provided. Speed up is limited.
[0008]
In addition to the shift mechanism described above, the lane change mechanism is provided to distribute the electronic components one by one to a plurality of packing tapes arranged in parallel to each other, which complicates the system. Therefore, the frequency of failures is potentially high, and there is a possibility that additional costs are required for maintenance.
[0009]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide an electronic component processing and tape packaging system that can achieve higher speed than the conventional one.
Another object of the present invention is to provide an electronic component processing and tape packing system that can increase the speed of the system while avoiding complication of the system and generation of additional maintenance costs. .
[0010]
[Means for Solving the Problems]
According to the present invention, such a technical problem is
A plurality of rotary transport mechanisms arranged successively,
A holding means that is arranged on an outer peripheral portion of each rotary transfer mechanism, and holds a plurality of the same number of electronic components as a set in all of the plurality of rotary transfer mechanisms;
Among the plurality of rotary transport mechanisms, there is a plurality of packing tapes that are arranged adjacent to the rearmost rotary transport mechanism and receive electronic components from the rearmost rotary transport mechanism and accommodate them. And
The holding means included in the rearmost rotary transport mechanism among the plurality of rotary transport mechanisms holds the set of electronic components apart from each other in the radial direction of the rearmost rotary transport mechanism,
The plurality of packing tapes are spaced apart from each other along the rotation direction of the rearmost rotary transport mechanism, and each packing tape extends linearly from the center of the rearmost rotary transport mechanism. This is achieved by providing an electronic component processing and tape packaging system characterized by being arranged along the line.
[0011]
In other words, according to the electronic component processing and tape packaging system of the present invention, the plurality of rotary transport mechanisms are configured from the frontmost rotary transport mechanism to the rearmost rotary transport mechanism, with the same number of electronic components as a set. Transport. Then, in the rotary transport mechanism at the rearmost stage for supplying electronic components to the packing tape, the electronic components forming a set are held in a state of being separated from each other in the radial direction of the rotary transport mechanism. The plurality of electronic components constituting the set are individually released and accommodated in a plurality of packing tapes arranged along the radial direction of the last rotary conveyance mechanism.
[0012]
From this, since the same number of electronic components are transported as a set from the beginning to the end of a plurality of continuously disposed rotary transport mechanisms, a conventional shift mechanism can be eliminated, In addition, a plurality of packing tapes are arranged apart from each other in the circumferential direction of the rotary transport mechanism at the last stage, and this packing tape is arranged along the radial direction of the rotary transport mechanism. A conventional lane change mechanism can be dispensed with to individually distribute a plurality of electronic components conveyed as a set to each packing tape. Therefore, according to the present invention, it is possible to increase the speed while avoiding the complexity of the system and the generation of additional maintenance costs.
[0013]
