The circuit board 900 is placed in the two side frames 112 and moves in a direction parallel to the two side frames 112 .

As shown in FIG. 1 and FIG. 3 , the circuit board 900 moves between the two side frames 112 and moves at a positioning height F. As shown in FIG.

As shown in FIG. 1 and FIG. 2 , the conveying device 120 is disposed in the accommodating track 110 for driving the circuit board 900 so that the circuit board 900 moves between the two side frames 112 and along the parallel direction of the two side frames 112 . In a specific application example, the conveying device 120 includes two conveying belts 122 respectively disposed on the two side frames 112 , and the two conveying belts 122 carry the two sides of the circuit board 900 respectively. In addition, the conveying device 120 further includes at least one extension carrier 124 connected to one of the two conveying belts 122 . When the width of the circuit board 900 is less than the distance between the two conveyor belts 122, one of the conveyor belts 122 carries the circuit board 900 through the extension carrier 124, thereby avoiding that the width of the circuit board 900 is too small to cause the two conveyor belts 122 to directly Problems carrying the circuit board 900 .

As shown in FIG. 2 , in a specific application example, the first lifting device 200 , the horizontal driving device 400 and the second lifting device 500 are respectively hydraulic actuating devices. However, the hydraulic actuating device is only an example, and it is not excluded to replace the hydraulic actuating device with a combination of a motor and a screw.

As shown in FIG. 2 , the first lifting device 200 and the horizontal driving device 400 are disposed on the bottom plate 114 . The fixed block 300 is connected to the first lifting device 200, and the first lifting device 200 is used to provide a linear output to drive the fixed block 300 to lift between the positioning height F and a release height R lower than the positioning height F.

As shown in Figure 3, Figure 4 and Figure 5, when the fixed block 300 is at the positioning height F, the height of the bottom surface of the fixed block 300 is lower than that of the bottom surface of the circuit board 900 and the height of the top surface of the fixed block 300 is higher than that of the circuit board At the position of the top surface of the circuit board 900 , one side of the circuit board 900 can abut against the fixed stopper 300 , so that the fixed stopper 300 stops the circuit board 900 . When the fixed block 300 is at the release height R, the height of the top surface of the fixed block 300 is lower than the bottom surface of the circuit board 900, so the circuit board 900 can continuously move in the accommodating guide rail and pass above the fixed block 300 .

As shown in FIG. 2 , the second lifting device 500 is connected to the horizontal driving device 400 , and the horizontal driving device 400 is used to provide a linear output to drive the second lifting device 500 to approach or move away from the horizontal driving device 400 . The moving stopper 600 is connected to the second lifting device 500 , and the second lifting device 500 is used to provide a linear output to drive the moving stopper 600 up and down at the positioning height F and the release height R.

As shown in Figures 4 and 5, when one side of the circuit board 900 abuts against the fixed block 300, the second lifting device 500 can further drive the movable block 600 to the positioning height F, so that the height of the bottom surface of the movable block 600 It is lower than the bottom surface of the circuit board 900, and the height of the top surface of the moving block 600 is higher than the top surface of the circuit board 900, so as to stop the circuit board 900.

As shown in FIG. 3 , when the fixed block 300 moves to the release height R and the circuit board 900 is released, the second lifting device 500 also lowers the height of the movable block 600 to the release height R, so that the top surface of the movable block 600 The height is lower than the bottom surface of the circuit board 900 . Therefore, the next circuit board 900 can pass above the moving block 600 to reach the predetermined position. At the same time, before the moving block 600 rises to the positioning height F, the horizontal driving device 400 drives the second lifting device 500 away from the first lifting device 200 . Therefore, in the process of moving the stopper 600 to the positioning height F, the distance between the moving stopper 600 and the fixed stopper 300 is greater than the length of the circuit board, so as to prevent the movement of the moving stopper 600 from rising to the positioning height F. The plates 900 interfere with each other.
