[0007]

In the present invention configured as described above, when the substrate supporting frame is brought closer from above the socket, the first ,
When the other ends of the two, three and four short arms abut on the socket side, and the first , two, three and four short arms are rotated by a predetermined angle synchronously by the rotating mechanism, the circuit board is moved with respect to the socket. It is gradually mounted close to the socket while maintaining the parallel state.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a board mounting apparatus according to one embodiment of the present invention.

In FIG. 1, integrated circuits 2 are arranged in a matrix on the surface of a wiring board 1 (circuit board), and a large number of input / output pins 3 connected to the integrated circuit 2 are provided on the back of the wiring board 1. It is connected to the wiring board 1 in a state of extending vertically.

The wiring board 1 is supported by a board frame 4.
The substrate frame 4 has a shaft 5 rotatably with respect to the substrate frame 4.
a, 5b are supported, and disc-shaped plate cams 6a1, 6a2, 6b1, 6b are provided at both ends of the coaxial 5a, 5b.
2 (short arm) is fixed slightly eccentric from the axis.

The plate cams 6a1, 6b1 and the plate cams 6a2, 6
Links 7a and 7b are rotatably connected to b2, respectively, and synchronize the rotations of the plate cams 6a1 and 6b1 with the plate cams 6a2 and 6b2.

On the other hand, on the upper surface of the motherboard 8 to which the wiring board 1 is connected, the connector housing 9 (socket) into which the input / output pins 3 connected to the back surface of the wiring board 1 are inserted to make electrical connection. And a guide plate 11 having guide pins 10a, 10b, and 10c vertically provided around the connector housing 9. As shown in FIG.

At positions corresponding to the guide pins 10a, 10b, 10c on the substrate frame 4, guide holes 12a, into which the guide pins 10a, 10b, 10c are inserted, are provided.
12b and 12c are provided, and a lever 13 for rotating the shaft 5a is fixed to the shaft 5a.

Next, the operation of this embodiment having the above configuration will be described. Guide pins 10 a, 10 b, and 10 c fixed to a guide plate 11 of motherboard 8 are inserted into guide holes 12 of substrate frame 4.
a, 12b, and 12c, the wiring board 1 and the connector housing 9 are aligned, and the wiring board 1 is brought close to the connector housing 9. When the input / output pins 3 are inserted into the connector housing 9, As shown in FIG. 2, the plate cams 6a1, 6a2, 6b1, and 6b2 come into contact with the motherboard 8.

In this state, when the lever 13 is rotated counterclockwise while pressing the substrate frame 4 downward, each plate cam 6 is rotated.
a1, 6a2, 6b1, and 6b2 rotate in synchronization with the rotation of the lever 13 to bring the board frame 4 and the motherboard 8 closer to each other while keeping them parallel.

As the board frame 4 gradually approaches the motherboard 8, the input / output pins 3 are inserted vertically into the connector housing 9 and are completely connected as shown in FIG.

When removing the board frame 4 from the motherboard 8, the input / output pins 3 are vertically disengaged from the connector housing 9 by rotating the lever 13 clockwise.
