Description

[0001]
[Industrial application fields]
The present invention relates to a tape feeder and a component supply device.
[0002]
[Prior art]
As shown in FIG. 6A, a carrier tape T used in a conventional apparatus for supplying electronic components is loaded with an electronic component single piece E in a storage pocket T2 of an embossed tape T1 having a feed hole T3. This is a packaging material that protects the electronic component E from external force due to transportation or the like by thermocompression bonding of the cover tape T4 to the upper part of the tape T1, and at the same time, is based on a packaging method corresponding to automatic mounting by an automatic machine.
[0003]
FIG. 6B is an example of a component supply apparatus using the carrier tape T. This apparatus is composed of intermittent feeding means 61 for intermittently feeding a carrier tape and peeling means 62 for peeling the cover tape T4 from the intermittently fed carrier tape T. The intermittent feeding means 61 includes a body 61a fixedly disposed on the mounting base 63, a sprocket 61b rotatably supported on the body 61a, and a drive source (not shown) that intermittently drives the sprocket 61b. Further, the stripping means 62 includes a guide 62a fixedly disposed on the mounting base 63, a reel 62b rotatably supported by the guide 62a, a drive source (not shown) that intermittently rotates the reel 62b, It consists of a peeling pin 62c provided on the body 61a.
[0004]
In this apparatus, the carrier tape T is intermittently fed by the intermittent rotation of the sprocket 61b engaged with the feed hole T3 of the carrier tape T, and the cover tape T4 corresponding to the intermittently fed length is wound up by the reel 62b. It can be peeled off from T. The electronic component E exposed by peeling off the cover tape T4 is taken out from the storage pocket T2 of the embossed tape T1 by a suction nozzle (not shown) or the like.
[0005]
[Problems to be solved by the invention]
By the way, as a carrier tape for supplying parts for mass production, an electronic component manufacturer sells about 2000 parts taped and wound on a reel when manufacturing parts. Even if you wish to purchase hundreds of parts, you can only purchase them in reel units, and the parts will be in excess inventory.
On the other hand, electronic parts manufacturers sell products with 25 to 50 parts inserted into small containers (sticks), and end users can purchase them in units of sticks, but there is no concern about excess inventory. The component supply device that is set and used is more expensive than the component supply device that uses the carrier tape, and the production cost is increased. For this reason, the end user purchases the stick and asks an external taping maker or introduces a taping machine inside to carry out the taping work. In this case, there is a problem that the taping cost per part becomes high.
[0006]
Further, the conventional carrier tape has a complicated mechanism for peeling the cover tape when it is mounted on the component supply device, and the component supply cassette becomes expensive. Further, since the mechanism is complicated for the work of peeling the cover tape, it takes time to load and remove the electronic parts.
[0007]
On the other hand, in production on a high-speed chip mounter line, there are various problems in small-volume production and trial production. It seems that there are many restrictions on taping. For example, there are restrictions on purchasing a small amount of parts, costs, time and labor required for taping of loose parts, inventory of surplus parts, loading into a cassette, removal time, and the like.
[0008]
An object of the present invention is to provide a tape feeder and a component supply device that can use a cover tapeless carrier tape to solve the above-described conventional problems.
[0009]
