The fourth lead screw 252 is connected with an output end of the fourth stepping motor 251, and is suitable for performing axial rotation movement under the driving of the fourth stepping motor 251; the fourth slider 253 is threadedly connected to the fourth lead screw 252 and adapted to perform a translational motion according to the rotation of the fourth lead screw 252.

The fixed bracket 263 is provided with a fixed plate 267, the fourth stepping motor 251 is fixed on the fixed plate 267, and the side plate 243 of the grabbing frame 24 is fixedly connected with the fourth slider 253. the fourth stepping motor 251 drives the fourth slider 253 to perform translational motion (i.e., motion in the left-right direction in fig. 13, and translational motion in the direction perpendicular to the paper surface in fig. 16) perpendicular to the cylinder 12, the second cylinder 22, and the second lead screw 212.

As shown in fig. 16, in the feeding area, the slide bar 3 is arranged on the steel belt through the adjusting clamp, the steel belt is provided with the upper clamp, the bottom of the slide bar 3 is provided with the lower clamp 4, the lifting mechanism 1 is fixed on the frame of the feeding frame and located right below the lower clamp 4, when the height of the lower clamp 4 needs to be adjusted, the second cylinder 22 drives the grabbing and pulling part 23 to perform translational motion towards the slide bar 3, the slide bar 3 is clamped in the accommodating area of the grabbing and pulling part 23, the second stepping motor 211 drives the grabbing and pulling part 23 to move downwards through the second fixing plate 214, when the grabbing and pulling part 23 moves downwards to contact with the upper end face of the lower clamp 4, the grabbing and pulling part 23 continues to move downwards, the lower clamp 4 and the slide bar 3 are driven to move downwards for a second distance , so that the position of the lower clamp 4 is lower than the preset height to be adjusted, then the second cylinder 12 drives the riding wheel 14 to move upwards according to the preset value, the riding wheel 14 is provided with a position sensor electrically connected with the PLC, when the riding wheel 14 contacts with the lower clamp 4, the position sensor can detect signals, at this time, the second dragging motor 211 can be started, so that the second riding wheel 211 moves upwards, and the second cylinder 211.

The height of the lower clamp 4 is determined by the pull-down mechanism 2 through two actions of pulling down the th distance and lifting the lifting mechanism 1 by the second distance, so that the height of the lower clamp 4 is more accurately positioned, the bottom of the lower clamp 4 is clamped in the groove of the riding wheel 14, the riding wheel 14 supports the lower clamp 4 and the sliding rod 3, and the lower clamp 4 and the sliding rod 3 are prevented from shaking in the process of installing a circuit board.

For example, when the lower fixture 4 needs to descend by 300mm, the distance from the supporting roller 14 of the lifting mechanism 1 to the lower fixture 4 at the initial position is set to 350mm, the lower fixture 4 is pulled down by 350mm through the grabbing and pulling component 23, so that the lower fixture 4 is in contact with the lifting mechanism 1, and the position sensor detects the lower fixture 4, then, the -th air cylinder 12 is started, the grabbing and pulling component 23 is started to move upwards, and the lower fixture 4 is driven to move upwards by 50mm together, so that the accurate positioning of the lower fixture 4 can be realized.

During the process of pulling down the gripping and pulling component 23, the sliding rod 3 and the lower clamp 4 continue to convey forwards along with the steel belt, and the controller of the fourth stepping motor 251 can calculate the rotating speed of the fourth stepping motor 251 according to the output signal of the steel belt transmission, so as to drive the pull-down frame of the pull-down mechanism 2 to synchronously transmit along with the steel belt. The steel belt does not need to stop working in the positioning process, and the production efficiency can be obviously improved.

After the lower clamp 4 is positioned, the upper clamp is opened through the upper clamping opening mechanism, the lower clamp is opened through the lower clamping opening mechanism, the plate is clamped between the upper clamp and the lower clamp through a mechanical arm or a manual work, the feeding is completed, and then the plate is conveyed forwards along with the steel strip to enter a lower process, such as an electroplating process or an etching process.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
