Problems solved by technology
[0006] However, there is an unsolved problem in that it is impossible to judge whether the fitting of the connecting pin by the pin insertion device is hindered, and it can be confirmed visually when the connecting pin is broken, but if the connecting pin is bent or the connecting pin is In the case of inclination, if the curvature and inclination are large, it can be confirmed visually, but if the curvature and inclination are small, it is difficult to visually confirm it, and it is impossible to accurately determine whether the pin insertion state is good or not

Embodiment Construction
[0031] Next, the pin insertion device according to the present invention will be described with reference to the drawings.
[0032] First, the conductive connecting cylinder 1 to which the present invention can be applied and the conductive connecting pin 2 press-fitted into the connecting cylinder 1 will be described.
[0033] The connection cylinder 1 is formed of copper, for example. Such as figure 2 As shown, the connection cylinder 1 is composed of a hollow cylindrical portion 1a and radially extending flange portions 1b and 1c formed at both ends of the cylindrical portion 1a. In the flange parts 1b and 1c, a notch part 1d for allowing solder to flow in and out is formed on the outer peripheral side. And, if figure 1 (a) and figure 1 As shown in (b), in such a way that the cylindrical portion 1a of the connecting cylindrical body 1 is perpendicular to the upper surface of the insulating circuit board 3, one flange portion 1c of the connecting cylindrical body 1 is...

The invention provides a pin inserting device capable of judging whether pin insertion is in a good condition or not correctly and a poor pin insertion judging method. The pin inserting method is used for pressing a pin (2) into a hollow cylinder (1) fixed on a base board (3) and is provided with a pin insertion head (14) retaining and inserting the pin (2) into the cylinder (1), a vibration sensor (25) mounted on the pin insertion head (1) and detecting vibration energy when the pin insertion head (14) inserts the pin (2) into the cylinder (1), and a poor pin insertion judging part judging whether poor pin insertion occurs or not according to the vibration energy detection value detected by the vibration sensor (25) and a threshold value.
Description
technical field [0001] The present invention relates to a pin insertion device for press-fitting a pin into a hollow cylinder fixed to a substrate, and a method for judging poor pin insertion. Background technique [0002] For example, in an insulating circuit board used in a power semiconductor module, when connecting pins for external connection are arranged on the insulating circuit board, one of the cylindrical connecting elements having flanges at both ends The flange portion is welded to the insulating circuit board, and the connection pin is press-fitted from the other flange portion side by a pin insertion device (for example, refer to Patent Document 1). [0003] Patent Document 1: Specification of US Patent Application Publication No. 2009 / 0194884 Contents of the invention [0004] The problem to be solved by the invention [0005] In addition, in the conventional example described in the above-mentioned Patent Document 1, the connection pin is press-fitted in...
