DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of connecting a cover tape for sealing a carrier tape having a storage pocket for storing chip type electronic parts.

[0002]

2. Description of the Related Art A carrier tape used for housing chip-type electronic parts and the like is used by sealing a cover material in a parts housing pocket which is continuously formed by molding. In the processes such as automatic loading of chip type electronic parts on carrier tape and mounting on printed circuit boards, automation of mounting work and speedup are rapidly progressing, and these automatic machines operate more efficiently for a long time in each process. Although efforts are being made, carrier tape cutting processing and cover tape cutting processing can be carried out when troubles such as automatic loading of chip type electronic components on a carrier tape and mounting on a printed circuit board are encountered. The connection method of the cover tape has been established, but the connection method of the cover tape has not been completed yet. Connection of the cover tape from the prior art, as shown FIG. 2, the trouble when the trouble occurs that sealed to the carrier tape 2 is provided with the storage pocket 3 which houses the sprockets 4 and the chip-type electronic component during mounting Peel off the cover tape 1 at the part where it happened , cut the seam part linearly, re-seal a new cover tape 1 again, and attach it to the cut surface.
And sealed by connecting the following cover tape, on top of the joint portion
Processing such as pasting the adhesive tape 5 as shown in Figure 3 has been performed to. In this method, since the joint portion of the cover tape is linear when the cover tape is peeled off, the peeling of this joint portion indicates that the adhesive force between the adhesive tape 5 and the cover tape 1 is weak, as shown in FIG. There is a defect that the cover tape cannot be continuously peeled off because it is peeled off between the adhesive tape 5 and the cover tape 1. Therefore, there has been a long-felt need for a method of connecting cover tapes that allows the connection portion of the cover tapes to be peeled off stably.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to solve these problems of the prior art, to simplify the connecting method, to reseal the tape, and to provide sufficient peeling strength at the connecting portion. This is to provide a cover tape connecting method that is economically advantageous.

DISCLOSURE OF THE INVENTION The inventors of the present invention have carried out a cover tape cutting process for cutting a carrier tape, a cover tape, a chip electronic part trouble, etc. due to a trouble that occurs when a chip type electronic part is automatically loaded and sealed in a carrier tape. As a result of various studies on effective connection method of the cover tape to the above, it is appropriate to use the adhesive tape of the surface material of the base material resin in order to obtain physical strength equal to or higher than the base material of the cover tape, cutting operation of the tape connection end is simple and easily be, completed the present invention found that etc. such as <br/> this the seal and the separation of the cover member does not hinder tape connection is a prerequisite It has come to do. The present invention provides a chip-type electronic component continuously-formed carrier tape storage pocket for accommodating and separating the cover tape that has been previously sealed yield
A package that takes out chip-type electronic components from the delivery pocket.
Connect the cover tapes together and cut the cover tapes.
Butt each other and stick adhesive tape over the connection.
In the combined method, the adhesive tape spreads toward the end in the peeling direction of the cover tape by the mountain-shaped butting in which the connecting portion of the cover tape divides the cover tape width into two parts or the starting point is one point in the width direction of the cover tape. It is a method of connecting the cover tapes connected by

The present invention will be described in detail with reference to the drawings.
The portion of the cover tape 1 sealed by the carrier tape 2 having the sprocket 4 and the storage pocket 3 for storing the chip-type electronic components peeled off due to a trouble is cut by a cutting jig to remove the left cover tape and the right cover tape. Cut with a jig such as a mountain-shaped jig so that the seam becomes a mountain shape that spreads toward the end in the direction of peeling, and cut the cut edges of the left and right cover tapes so that the seam does not overlap. (Not shown).
The part separated from the carrier tape is resealed to the carrier tape with the connected cover tape to complete the connection of the cover tape. What is important here is that the side where the peeling starts (the side where the peeling starts is the right side in the drawing) is the inverted mountain-shaped cut end, and the side where the peeling continues (left side) ) The connecting seam part must have a mountain-shaped cut end. The connected seams are not straight, but mountain-shaped. At the seams, the adhesive tape adheres to both sides of the right and left cover tapes, so the cover tape is peeled off and then the seam is peeled off. At this time, even if the adhesive force between the adhesive tape and the cover tape is weak, the joint tape has a uniform adhesive force, so that the cover tape is smoothly and stably separated from the carrier tape.

[0006]

According to the present invention, the peeling of the portion where the connection repair is performed due to the mounting trouble of the chip type electronic component on the carrier tape starts from the portion where the peeling of the connecting portion of the cover tape is not sealed, and the usual cover tape. The same peeling effect as is obtained.
