At this time, the latch 120 connected to the other end of the rotation link 133, the center of which is rotatably fixed to the movable body 134, in the state in which the hook 121 of the tip is inserted into the insertion groove B1 of the board B. The board B is pulled in the direction of the connector while interlocking with the movement in the X-axis direction of the movable body 134 so that the tip of the board B is connected to the connector (see FIG. 5C).

As described above, after the board B is towed to the board B to be connected to the connector, the board B is detached from the connector.

Looking at such a separation action, as shown in Figure 9d, when the action rod of the drive means 110 is lowered and the moving bar 131 is guided by the roller 141 is vertically lowered in the Y-axis direction, the connecting link (132 ') Is rotated about the center portion connected to the guide 140 ', and one end of the rotation link 133 connected to the other end of the linking link 132' is centered on the center portion rotatably fixed to the movable body 134. The rotation of the rotational link 133 is restricted while the other end of the rotational link 133 is caught by the stopper 134b of the movable body 134.

Here, the guide portion 130 that receives the driving force of the driving means 110 through the moving bar 131 and the connecting link 132 ′ is the first elastic member by the coupling force of the board (B) inserted into the connector. Prior to the horizontal movement of the movable body 134 elastically supported by 136, the rotary link 133 is rotated, together with the second elastic member (134) disposed between the movable body 134 and the rotary link 133 ( 137 is tensioned.

In addition, the latch 120 connected to the other end of the rotating link 133 is the same as the center of rotation of the rotating link 133 at the same time the rotating link 133 is pivotally fixed to the moving body 134 so as to rotate. The hook 121 formed at the tip of the latch 120 is separated from the insertion groove B1 of the board B while descending into an arc of a radius. (See FIG. 5D)

9E illustrates a state in which the driving rod 110 continuously descends from the state of FIG. 9D, and the moving rod 131 is guided by the roller 141 as the acting rod of the driving unit 110 descends. While continuously falling vertically in the Y-axis direction, the connecting link 132 ′, which is pivotally assembled to the guide 140 ′, rotates and presses one end of the rotating link 133. Since the other end of the 133 is caught in the stopper 134b of the movable body 134, the rotation is limited, and thus, the movable body 134 moves along the guide pin 135 in the X-axis direction. The first elastic member 136 elastically supporting the 134 is elastically restored.

Here, the connecting portion of the connecting link 132 'and the moving bar 131 is guided by the first arc hole 144 of the guide 140', the connecting link 132 'and the rotating link 133 The connection part of the) is guided by the second arc-shaped hole 145 of the guide 140 '.

At this time, the latch 120 connected to the other end of the rotation link 133 fixed to the movable body 134 is a movable body in a state in which the hook 121 of the front end of the latch 120 is separated from the insertion groove B1 of the board B. As the body of the latch 120 pushes the front end of the board B by the movement in the X-axis direction of the 134, the board B is detached from the connector.

The hook 121 of the latch 120 that is moved by the guide portion 130 of the second embodiment of the board detachment apparatus of the present invention as described above is the same as the moving state described with reference to FIG. 6 in the above-described first embodiment. .

According to the second embodiment of the board attachment and detachment device of the present invention as described above, when the moving bar 131 is raised, the connecting link 132 ′ and the rotating link 133 rotate together, and the latch 120 is in an arc-shaped diagonal direction. As the ascending link 133 is caught by the movable body 134 and the pivoting link 120 moves backward in a restricted state, the latch 120 moves backward, and when the movable bar 131 descends, the link link 132 'and the pivot link As the 133 rotates together, the latch 120 descends in the oblique direction of the arc shape, and the pivoting link 133 is advanced while being caught by the stopper 134b of the movable body 134.

That is, the driving force of the moving bar 131 which moves up and down in the Y-axis direction is transmitted to the rotation link 133 through the connection link 132 ′ which is bent at the center and is rotatably fixed to the guide 140 ′. By the rotation of the 133, the latch 120 is raised / lowered in the oblique direction of the arc shape, when the rotation link 133 is rotated by a predetermined angle is caught by the moving body 134 moving in the X-axis direction rotation link 133 As the movable body 133 moves in the X-axis direction, the latch 120 moves forward and backward.

In particular, the center is bent and rotatably fixed to the guide 140 ', one end of which is connected to the moving bar 131, and the other end of the Y-axis direction through the rotation of the connecting link 132' connected to the rotation link 133. Since the driving force is transmitted in the X-axis direction, the driving force of the driving means 110 can be transmitted to the latch 120 as it is. Thus, it is possible to attach and detach a plurality of boards B to the connector at one time.

In addition, the connection link 132 ′ is connected to the pivot link 133 from a central portion rotatably assembled to the guide 140 ′ so as to act as a lever in transmitting the driving force of the movable bar 131. The length from the center portion to the connecting portion connected to the moving bar 131 may be longer than the length up to.
