Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting electronic components with leads on a substrate.

[0002]

2. Description of the Related Art Conventionally, a clinch for detecting insertion and fixing a component is provided as well. As shown in FIG. 5, a piezoelectric element 8 is attached to a claw 7 for clinching so that the clinch can be properly inserted. When the clinch is performed, the lead 3 comes into contact with the claw 7, and the stress generated at that time is detected by the piezoelectric element 8 for inspection. If the lead 3 is not properly inserted, the lead 3 does not come into contact with the clinch claw 8. Therefore, stress is not transmitted to the piezoelectric element 8 and it is determined that the lead element 3 is inserted incorrectly.

[0003]

However, since such a conventional insertion detecting device also functions as a clinch, only the clinching leads can be detected, and normally only two leads can be detected, and more than that. Parts having a large number of parts were not inspected except for the lead for clinching, and there was a problem that they were not found even if there was an insertion error. Further, there is a problem that a component having a thick lead and which cannot be clinched cannot be inserted by the mounting machine.

Therefore, in order to solve such a conventional problem, the present invention separates the insertion detecting device and the clinch device into separate devices, and provides an independent insertion detecting device for each lead of the component, The purpose is to enable insertion detection of all parts and all leads. After the insertion is detected, the clinching is performed by a device similar to the conventional one, if necessary.

[0005]

In order to solve the above problems, the insertion detecting apparatus of the present invention detects the lead of a component in order to judge whether the component is inserted correctly or not. It is characterized in that it is equipped with a detector.

[0006]

According to the above insertion detecting apparatus, since the insertion inspection of all the leads is performed, it is possible to detect even if only one lead is inserted, and it is possible to find a defect that cannot be detected by the conventional method.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of the apparatus of the present invention. The object is the component 1 and its leads 2 and the substrate 3, and the device of the present invention is applicable to the detection plate 4 and its operation for inspecting whether the leads 2 are inserted into the holes of the substrate 3 or not. It is composed of a photosensor detector 5 which determines whether or not the insertion is made. Further, in the standby state where no component is inserted, the detection plate 4 is in a state in which the end face of the component that contacts the lead 2 is lifted.

FIG. 2 illustrates the operation of the present invention when the component 1 is inserted correctly. In FIG. 2, when the component 1 is inserted into the hole of the substrate 3, the lead 2 of the component 1 is attached to the substrate 3
Comes down to the bottom of. The detection plate 4 is in the shape of a seesaw supported at one point, and when the tip of the detection plate 4 is pushed down by the lead 2 of the component 1, the other tip of the detection plate 4 is lifted up. The detector 5 monitors the tip of the detection plate 4 opposite to the end face in contact with the lead 3, and when the component 1 is not inserted, the detection plate 4 is detected.
If the detection plate 4 is lifted by inserting the lead 2, the detector 5 does not have the detection plate 4 because the detection plate 4 is out of the monitoring range of the detector 5. to decide. This change in the determination made by the detector 5 enables the determination that the insertion has been performed correctly.

FIG. 3 is an operation explanation of the present invention when the component 1 is not inserted correctly. In FIG. 3, when the lead 2 of the component 1 is not inserted into the hole of the substrate 3 due to some reason such as bending of the lead 2 and deviation from the hole position of the substrate 3, the lead 2 of the component 1 moves down on the lower surface of the substrate 3. Since the detector plate 4 does not move, the detector plate 4 does not operate, and the detector plate 4 is in the monitoring range of the detector 5, and the detector 5 does not change from the standby state, and it can be determined that there is an insertion error.

FIG. 4 shows an embodiment in which the number of leads of parts is large. No matter how many leads you have,
Even if one lead is not inserted by attaching the same number of detection plates 4 as the number of leads of the component, the detector is
There is no change from the standby state and it can be determined that there is an insertion error.

[0012]

As described above, the insertion detecting device of the present invention has a simple structure in which the detection plate provided for each number of leads of the component and the detector for monitoring the operation of the detection plate perform the insertion detection. The effect is that insertion errors of all leads can be detected.
