Description

Electronic component packaging carrier tape guiding method and device

The present invention relates to a guiding method and device, in particular to a guiding method and device for an electronic component packaging carrier tape used to guide an electronic component packaging carrier tape into a reel.

According to the general electronic components have different physical characteristics, they often need to be packaged or sorted through testing and classification procedures. When packaging is performed, a carrier tape with a loading slot is often used to accept the electronic components that have been tested one by one. The carrier slots of each kind of carrier tape are arranged one by one along the length of the carrier tape. Above each carrier slot is an opening for placing electronic components, and equidistantly arranged caulking holes are arranged on one side of the carrier groove. These caulking holes are used to help The carrier tape is embedded and conveyed; and after the carrier tape has placed the electronic components one by one in each of the carrier slots, the carrier tape is covered by a pair of carrier tapes with adhesive tape on one side, and then each of the carrier slots is covered and then transported. The rolled magazine is rolled up.

When the carrier tape which has been covered by the tape-like sticker with adhesive is rolled up, it is usually necessary to provide a path for conveying the carrier tape and a path for conveying a tail of the sticker so that the carrier tape is on the path for conveying the carrier tape. After being cut, and making the adhesive tape cut in the path of conveying the adhesive tape, when the carrier tape is rolled up to the end, the adhesive tape is conveyed and affixed with the tail end of the carrier tape in the same conveying path and pasted. , And then transported into the rolling magazine to be rolled together, and at the same time when being rolled, the part of the original adhesive sticker that was not adhered to the end of the carrier tape was pushed and stuck to the previous circle of the rolled carrier tape. On the circumference so that the carrier tape that has been completely wound up will not loosen.

The previous technology did not consider the possible deformation of the carrier tape during the rewinding, because The carrier tape is a flexible slender ribbon-shaped body made of plastic material. Especially after the entire length of the carrier tape is covered with an adhesive tape-shaped sticker with an adhesive, the straight length of the carrier tape may be curved to one side. At the same time, the tape-like sticker or the tail sticker may be unevenly adhered to the side of the carrier tape. Because the winding path of the cassette itself is quite narrow, the gap between the tape and the carrier tape is extremely close. The carrier tape conveying path is designed to be very close to guide the carrier tape to be smoothly transported into the reel. Therefore, the carrier tape is bent to one side or deformed, or the tape-shaped stickers and tail stickers are not adhered to the carrier. The phenomenon on the side of the belt will cause the carrier tape to be blocked during transportation, affecting the progress of the winding operation!

That is, an object of the present invention is to provide a method for guiding a carrier tape of an electronic component, which makes a carrier tape more smoothly on a path conveyed to a reel via a conveying device.

Another object of the present invention is to provide an electronic component packaging carrier tape guide device that makes the carrier tape more smoothly on the path conveyed to the reel via the conveying device.

Another object of the present invention is to provide a device for executing the method for guiding a carrier tape of an electronic component package.

The method for guiding a carrier tape of an electronic component package according to the purpose of the present invention includes: providing a carrier tape provided with a carrier groove, the carrier grooves are arranged one by one along the length of the carrier tape, and an electronic component is placed above each carrier groove. Providing a reel; the carrier slot of the carrier tape is accommodated in a groove-shaped guide slot of a guide device to be guided and conveyed, and an air channel is provided at the bottom of the guide slot, and the axis of the air channel hole At an angle of less than ninety degrees with the channel axis of the guide groove, a positive pressure gas is introduced from the air channel, so that the positive pressure gas is blown toward the bottom of the carrier tape in the guide groove, and the carrier tape is input into the roll Roll in the box.

An electronic component packaging carrier tape guiding device according to another object of the present invention includes: a first guide member, one end of which is driven to rotate around an axis so that a front end thereof swings up and down; A second guide is located under the first guide and fixedly positioned; the second guide is provided with a groove-shaped guide groove, and an air channel and a bottom of the second guide are provided at the bottom of the guide groove Externally communicating, the air passage can be passed into positive pressure gas; a first side and a second side are respectively provided on both sides of the guide groove;

According to another object of the present invention, an electronic component packaging carrier tape guiding device includes a device for performing the electronic component packaging carrier tape guiding method.

According to the method and device for guiding a carrier tape of an electronic component package according to the embodiments of the present invention, the adhesive tape is passed through a guide groove of a fixed second guide and a snap-in clip at one end. The guide flow path formed between the shaft is the center of the shaft and the other end can be tilted up and down. The guide flow path is guided into the reel, and the carrier tape can not only receive the positive airflow through the air passage in the guide groove. Pressurized gas floats and is transported without hindrance. At the same time, a gap is left between the first stopper and the outer surface of the first side of the second guide, so that the width of the carrier tape is affected by the first stopper and the second The restriction of the stopper, but the moderate deflection of the first stopper provides an automatic fine adjustment by the moderate deflection of the first stopper when the carrier tape has a deflection amount to one side. Change the size of the clearance to allow the arc-bend deformation carrier tape to pass through the distance between the bottom surface of the first guide member and the first side of the guide groove on both sides of the second guide member and the upper surface of the second side edge; When there is a phenomenon that the sealing tape-shaped sticker or the tail sticker is not adhered to the carrier tape and is shifted to the side of the carrier tape, the offset can also be adjusted by The first stopper member against the concave side of the cover is provided with spaced grooves to be provided to accommodate escape while avoiding the carrier tape during transportation is blocked, so that the retractor is operating smoothly.
