Detailed Description
The technical solution of the present invention is further described and illustrated by the following specific embodiments.
As shown in fig. 1 to 3, a PCB conveying and steering apparatus includes a frame 7, and the frame 7 is sequentially provided with a first conveying roller area for feeding a PCB, a second conveying roller area for steering the PCB, and a third conveying roller area for sending the steered PCB according to a conveying direction. The first conveying roller area is composed of a plurality of first conveying rollers 4 vertical to the side edge of the frame 7, the second conveying roller area is composed of a plurality of second steering rollers 5 with included angles smaller than 90 ℃ with the side edge of the frame 7, and the third conveying roller area is composed of a plurality of third conveying rollers 6 vertical to the side edge of the frame 7. The PCB conveying and steering device further comprises a stop lever 1, a screw rod sliding block mechanism 2 and a sliding rod 24. And one side of the frame 7 between the adjacent first conveying roller 4 and the second steering roller 5 is provided with a stop lever 1 for steering the PCB, and the other side is provided with a screw rod sliding block mechanism 2 for pushing the PCB to steer. The slide rod 24 is fixedly connected with the bottom end of the slide block 23 of the screw rod slide block mechanism 2, and the bottom end of the slide rod 24 is positioned between the adjacent first conveying roller 4 and the adjacent second steering roller 5 and moves between the adjacent first conveying roller 4 and the adjacent second steering roller 5 through the slide block 23.
In the conveying process, one side corner of the PCB firstly abuts against the stop lever 1, and the PCB turns around the side corner as the center under the action of the conveying roller. Then, the slide bar 24 pushes the other side of the PCB to assist the PCB to turn, at this time, the PCB enters the second conveying roller area, and the plurality of second turning rollers 5 further turn the PCB. This embodiment combines together through second turn to roller 5, pin 1, 2 three of lead screw slider mechanism, makes the PCB circuit board effectively turn to for transporting along length direction from original along the transportation on the width direction, turns to efficiently, turns to and expends time weak point, consequently can in time adjust the direction of placing of PCB circuit board according to the stoving needs.
The stop lever 1 is fixed on one side of the frame 7 through the first support frame 11, the stop lever 1 and the lead screw slider mechanism 2 are positioned on the left side and the right side of the length direction of the frame 7 and correspond to each other, namely the vertical distance between the stop lever 1 and the lead screw slider mechanism 2 from the starting end of the frame 7 is equal, and after the PCB is abutted against the stop lever 1, the lead screw slider mechanism 2 is started within the fastest time to enable the PCB to effectively turn, so that the position of the lead screw slider mechanism 2 is the best position for assisting in pushing the PCB to turn.
In order to ensure that the screw rod sliding block mechanism 2 is started in time, a position sensor is arranged below the position of the screw rod corresponding to the frame 7. When one side corner of the PCB touches the stop lever 1 to start turning, the other side corner of the PCB passes through the position sensor and delays for time t1, and the screw rod sliding block mechanism 2 is started and drives the sliding rod 24 to move to assist in pushing the PCB to turn.
