Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for packaging electronic parts, and is suitable for application to a method and apparatus for packaging electronic parts after determining the type of the electronic part such as an IC and then packaging the electronic parts. It is something.

[0002]

2. Description of the Related Art Conventionally, in the process of packaging electronic components such as ICs, the type of electronic components is discriminated as a pre-stage of packaging. As such a product type discrimination method, there is a method in which after the front surface side of the electronic component is imaged by a CCD camera, only the electronic component of a predetermined product type is transferred to the packaging process based on the imaging result.

[0003]

However, according to the method of discriminating the kind, only the surface side of the electronic part is imaged, and therefore, depending on the kind of the electronic part, the electronic parts other than the predetermined kind are of the predetermined kind. As a result of being discriminated as an electronic component, there is a possibility that an electronic component whose product type is erroneously recognized may be packaged.

The present invention has been made in consideration of the above points, and proposes a method and apparatus for packaging electronic components which can prevent erroneous packaging and reliably package only electronic components of a predetermined type. Is what you are trying to do.

[0005]

In order to solve such a problem, according to the present invention, an electronic component packaging method for packaging an electronic component in a predetermined package is obtained by imaging the front side and the back side of the electronic component. After determining the type of electronic component based on each of the obtained imaging results, only the electronic component of the type is stored in the package based on the determination result.

Further, according to the present invention, in the electronic component packaging apparatus for packaging electronic components in a predetermined package, the first transport means transports the electronic components to the image pickup position of the image pickup means, and the image pickup means is the surface of the electronic components. The side and the back side are respectively imaged. Subsequently, the discrimination means discriminates the type of the electronic component based on the image pickup result of the image pickup means, and then the second carrying means stores only the electronic component of the type in the package based on the discrimination result of the discrimination means. To do.

Since the front side and the back side of the electronic component are respectively imaged in this manner, it is possible to determine whether or not the electronic component is of a predetermined type with higher accuracy than in the case where only the front side of the electronic component is imaged. Can be determined.

In this case, the tape-shaped container 20 stores the electronic components 2 one by one in synchronization with the timing at which the electronic components 2 are transported by the second oscillating handler 5 under the control of the control unit. It is conveyed at the timing. After that, the electronic component 2 accommodated in the tape-shaped container 20 at a predetermined position on the pedestal 6A is sealed and packaged.

Incidentally, as shown in FIG. 3 (A), the electronic component 2 is, for example, a ceramic substrate 2A used for a filter or the like.
And a sealing portion 2B formed by sealing a capacitor and a resistor.
A plurality of electrodes 2C having a predetermined pattern are arranged on both end sides along the longitudinal direction via the electrodes 2C.

The camera 15 first detects a predetermined range (hereinafter, referred to as a position correction model range) S0 and S1 including each corner on one end side along the longitudinal direction of the electronic component 2 in the imaging range. Based on the detection result, the control unit corrects the inclination of the electronic component 2 in the vertical direction and the positional deviation in the XY directions.

Subsequently, the first CCD camera 15 has predetermined ranges (hereinafter referred to as inspection model ranges) M0 and M1 formed by dividing one end side of the electronic component 2 along the longitudinal direction of the imaging range into three. And M2 are detected. Based on this detection result, the control unit determines whether or not the electronic components 2 are different types.

After the image pickup by the first CCD camera 15 is completed, the control unit controls the driving of the first oscillator handler 4 so that the electronic component 2 is sucked and held by the robot arm 4A. Move to. In this state, the positioning mechanism 16 positions the electronic component 2 at a predetermined position under the control of the control unit, and then the second CCD camera 17 images the rear surface side of the electronic component 2. At this time, the second CCD camera 17 detects the position correction model range and the inspection model range on the back surface side of the electronic component 2 similarly to the first CCD camera 4.

When the electronic component 2 has a square shape, the position correction model ranges S0 and S1 and the inspection model ranges M0, M1 and M for the respective sides of the electronic component 2 are inspected.
Make sure to inspect item 2.

As described above, the control unit as the discriminating means determines that the electronic component 2 is not of a predetermined type in any one of the CCD cameras based on the determination results by the first CCD camera 15 and the second CCD camera 17. When it is determined that the second oscillator handler 5 is driven, the electronic component 2 is transferred from the positioning mechanism 16 to the NG transfer conveyor 18. After this, the NG conveyor 1
The electronic component 2 transferred to 8 is discharged to a predetermined discharge position.

On the other hand, when the control unit determines that the product is of a predetermined type, the second oscillator handler 5 is driven and controlled to move the electronic component 2 from the positioning mechanism 16 to above the NG transfer conveyor 18.
