Description

Electronic component packaging carrier tape guiding method and device

technical field

The invention relates to a guiding method and structure, in particular to an electronic component packaging tape guiding method and device for guiding the electronic component packaging tape into a reel.

Background technique

Due to the different physical characteristics of general electronic components, they often need to be packaged or classified through the procedures of detection and classification. When packaging, a carrier tape with a carrier slot is often used to carry the detected electronic components one by one. This kind of carrier The slots of the tape are arranged one by one along the length of the tape. The upper part of each slot is an opening for placing electronic components, and there are equidistantly arranged embedded holes on one side of the slot. These embedded holes are used to help the loading The tape is embedded and conveyed; after the carrier tape is placed in the slots one by one, the electronic components will be transported and covered with a tape-like sticker with adhesive on one side one by one, and then sent into the roll. The moving reel is retracted.

When the carrier tape covered by the adhesive tape-like sticker is rolled up, it is usually necessary to provide a path for conveying the carrier tape and a path for conveying a tail of adhesive tape, so that the carrier tape is on the path of conveying the carrier tape It is cut, and the tail glue sticker is cut in the path of conveying the tail glue sticker. When the tape has been rolled up to the end, the tail glue sticker is conveyed and the tail end of the carrier tape is intersected and pasted on the same conveying path. , and then transported into the rolling cassette to be rolled up, and at the same time as it is rolled up, the part of the tail tape that is not attached to the end of the carrier tape is pushed and adhered to the previous circle of the rolled up carrier tape On the circumference, so that the carrier tape that has been rolled up will not be loose.

Contents of the invention

The existing technology does not consider the possible deformation of the carrier tape when it is rolled up. Since the carrier tape is a flexible and slender strip made of plastic material, especially when the entire length of the carrier tape is covered with adhesive After the tape-like sticker, the linear length of the carrier tape may be bent to one side. At the same time, the tape-like sticker or tail glue sticker may be unevenly pasted and biased to the side of the carrier tape. Due to the reel itself The coil feeding path is quite narrow, and the gap between the width of the carrier tape is very close, so the path of the carrier tape delivery is designed to be very close, so as to guide the carrier tape to be smoothly transported into the coil box, so the carrier tape Bending to one side or tape-shaped stickers and tail glue stickers are not evenly pasted to one side of the carrier tape, which will cause the carrier tape to be blocked during transportation and affect the winding operation!

The purpose of the present invention is to provide a method for guiding the electronic component packaging carrier tape to make the carrier tape more smooth on the path of being transported to the reel via the conveying device.

Another object of the present invention is to provide a carrier tape guiding device for electronic component packaging that makes the path of the carrier tape transported to the reel via the conveying device smoother.

Another object of the present invention is to provide a device for implementing the electronic component packaging carrier tape guiding method according to any one of claims 1 to 5 .

According to the electronic component packaging carrier tape guiding method of the present invention, it includes: providing a conveying mechanism, provided with a first guide seat and a second guide seat to transport a carrier tape; providing a tail glue mechanism, provided with a first holding end and a second holding end to keep a glue tail; provide a coil box; make the carrier tape be cut by a cutter between the first guide seat and the second guide seat; make the tail glue be drawn through the second holding end The lower end of the rubber tail moves down to the second guide seat of the conveying mechanism and is attached to the carrier tape, so that the conveying path of the carrier tape and the tail rubber conveying path intersect; the attached tail rubber carrier tape is guided through a guiding device Transmission, and the carrier tape is input into the reel for winding; wherein, when the carrier tape passes through the guiding device, the width of the carrier tape is restricted, and the restriction of the width can be fine-tuned independently according to the deformation of the carrier tape .

According to another object of the present invention, the electronic component packaging carrier tape guide device includes: a first guide, one end of which is driven to rotate with an axis, so that the front end swings up and down; a second guide , located below the first guide and fixed at the location; the first and second guides are located between a conveying mechanism and a coil box for conveying the carrier tape, and a feeder is formed between the first and second guides A guide flow path for transporting the carrier tape; wherein, the width of the guide flow path restricts the carrier tape, and the restriction of the width can be independently fine-tuned according to the amount of deformation of the carrier tape.

According to still another object of the present invention, the electronic component packaging carrier tape guiding device includes a device for performing the electronic component packaging carrier tape guiding method according to any one of claims 1 to 5 .

The electronic component packaging carrier tape guiding method and structure of the embodiment of the present invention, because the adhesive tape has been attached, it is transported through a guide groove of a fixedly positioned second guide member and an embedded buckle clip at one end. The shaft in the mouth is the center of the shaft and the other end can be swung up and down. The guide flow path formed between the first guide parts is guided and sent into the reel, not only the carrier tape can be passed through the air channel in the guide groove Positive pressure gas floats on the top and is transmitted without hindrance. At the same time, the gap left between the first stopper and the outer surface of the first side of the second guide makes the width of the carrier tape limited by the first stopper and the second guide. The restraint of the second stop, but the moderately deflectable state of the first stop, provides that when the carrier tape has a bending deformation to one side, the moderate deflection of the first stop can be used for autonomous fine-tuning , changing the size of the clearance to allow the arc-bending deformation carrier tape to pass through the distance between the bottom surface of the first guide and the upper surface of the first side and the upper surface of the second side on both sides of the guide groove of the second guide; at the same time When there is a phenomenon that the tape-like stickers and tail glue stickers are not evenly pasted on the carrier tape and are shifted to one side of the carrier tape, the offset can also be set by the side of the first stop that is close to the distance. Concave escaping troughs are provided to accommodate them, so as to prevent the carrier tape from being blocked during transportation, so that the winding operation can be carried out smoothly.
