DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component carrier tape used when a component is mounted at a predetermined position on a circuit board by suctioning the component with a suction nozzle in order to mount the component at a predetermined position on the circuit board. The present invention relates to a method for removing parts used.

[0002]

2. Description of the Related Art In recent years, there has been a demand for downsizing of products, and accordingly, downsizing of components has been demanded. How to suck a component by a suction nozzle when taking out a small component from a component carrier tape is discussed. It is a problem.

[0003] A conventional component carrier tape and a method of picking up components using the same will be described below with reference to the drawings.

FIG. 6A is a top view of a conventional component carrier tape, and FIG. 6B is a sectional view of FIG. 6A. FIG. 7 is a perspective view of a reel on which a conventional component carrier tape is wound.

[0005] Reference numeral 1 in the drawing denotes a component carrier tape, which comprises a top tape 5, a tape base 7, and a bottom tape 8. Reference numeral 2 denotes a feed hole provided at a predetermined interval in the tape base 7, which is provided for moving the component carrier tape 1 to a predetermined speed or a predetermined position. Reference numeral 3 denotes a component storage portion, which is a space obtained by removing a part of the tape base 7, and reference numeral 4 denotes a component stored in the component storage portion 3. Note that a plurality of component storage units 3 are provided at predetermined intervals. Reference numeral 5 denotes a top tape provided on the upper surface of the tape base 7, and reference numeral 8 denotes a bottom tape provided on the bottom surface of the tape base 7. . 7 is a tape base, 6
Is a reel around which the component carrier tape 1 is wound.

Next, a method of picking up a component using the component carrier tape configured as described above will be described.

FIG. 8 is a sectional view of a main part of a conventional component carrier tape and a component take-out device. The same components as those in FIG. 6 are denoted by the same reference numerals.

Reference numeral 9 in the drawing denotes a peeling means for peeling off the top tape 5 from the tape base 7, a suction nozzle 10 for sucking the component 4 and taking out the component 4 from the component carrier tape 1,
A pin 11 pushes up the component 4 from the opposite direction of the suction nozzle 10. Note that the component carrier tape 1 is configured to move from right to left in FIG.

With this configuration, the part 4 is taken out in the following procedure. First, the top tape 5 is peeled from the tape base 7 by the peeling means 9. Next, when the component 4 comes to a predetermined position, the suction nozzle 10 descends to the upper surface of the tape base 7. FIG. 9 shows the positional relationship between the component storage unit 3 and the suction nozzle 10 from the upper surface at this time. 6 to FIG.
The same components as those in FIG. 8 are denoted by the same reference numerals. In the figure, t is the thickness of the suction nozzle 10.

The reason why the pins 11 are used is as follows. When the inner diameter of the suction nozzle 10 is reduced, the resistance of the inflow of air by the inner wall of the suction nozzle 10 relatively increases, so that the efficiency of suction is reduced. Therefore, it is desirable that the inner diameter of the suction nozzle 10 be as large as possible. However, if the inner diameter of the suction nozzle 10 covers the entire part 4, the part 4 is sucked into the component pick-up device through the inside of the suction nozzle 10. Therefore, the inner diameter of the suction nozzle 10 needs to be a size that does not cover the entire part 4.

On the other hand, when the suction nozzle 10 is enlarged and the outer diameter of the suction nozzle 10 completely covers the component storage section 3, the suction nozzle 10 sucks the component carrier tape 1 itself, and
Is difficult to adsorb. Therefore, the suction nozzle 10
Must be smaller than the component storage section 3.

In consideration of the above points, if the outside diameter is made smaller than the component storage section 3 while making the inside diameter of the suction nozzle 10 as large as possible, the thickness t of the suction nozzle 10 becomes thin and the strength is reduced. In particular, when the size of the component 4 is reduced, the size of the component storage unit 3 is also reduced. Therefore, the outer diameter of the suction nozzle 10 must be reduced, and the thickness t becomes extremely thin.

Therefore, in the prior art, the suction nozzle 10
The diameter of the suction nozzle 10 is increased to secure the necessary size and thickness for the inner diameter and the thickness t of the suction nozzle 10, and the outer diameter of the suction nozzle 10 completely covers the component storage unit 3. With respect to the decrease in the suction force, the component 4 is sucked by forcibly pushing up the component 4 to the vicinity of the suction nozzle 10 or until the component 4 comes into contact with the suction nozzle 10 by the pin 11.

[0014]

However, in the above-mentioned conventional configuration, a mechanism for pushing up the component 4 such as the pin 11 is required as shown in FIG. Had issues. In addition, there is also a problem that a trouble such as breakage of the component 4 due to pushing up the component 4 with the pin 11 may occur.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a component carrier tape capable of removing a component without an operation of pushing up the component, and a component removing method using the same. Is what you do.

[0016]

In order to achieve the above object, the present invention has the following arrangement.

The component carrier tape according to the first aspect of the present invention has, in particular, a groove for removing a part of the tape base and connecting to the component storage portion.
When the suction nozzle holds down the carrier tape, the air in the atmosphere flows in from the groove, and the suction nozzle has the effect of sucking the component.

In the component carrier tape according to a second aspect of the present invention, in particular, the groove is provided outward from the component storage portion, and the width of the connection portion with the component storage portion is equal to the width of the component storage portion. 10% to 60% of that of the suction nozzle, so that the component is normally sucked when the component is sucked while the component stored in the component storage unit is held at a predetermined position. Has the effect of being able to adsorb.

The invention according to claim 3 of the present invention particularly provides
A plurality of component storage portions are provided on the component carrier tape at predetermined intervals, and grooves are provided to connect adjacent component storage portions, whereby the component storage portions are arranged at narrower intervals. Can be provided.

The invention described in claim 4 of the present invention particularly provides
The tape base is made of a gas-permeable material, which has the effect that air in the atmosphere flows in from the tape base and components are sucked by the suction nozzle.

The invention described in claim 5 of the present invention particularly provides
In the step of sucking the component, the suction nozzle is brought into contact with the upper surface of the tape base so that the groove protrudes from the outer diameter of the suction nozzle, whereby air in the atmosphere flows from the groove, and the component is sucked by the suction nozzle. Has the effect of being adsorbed.
