The upper pressing rod 16, the second upper pressing rod 17, the third upper pressing rod 36, and the fourth upper pressing rod 37 prevent the PCB board from curling or tilting upwards; the device can drive the first sliding plate 12 to move through the first adjusting plate 8 that can move left and right, and drive the second sliding plate 32 to move through the third adjusting plate 28 that can move forward and backward, and drive the second adjusting plate 21 to move through the first sliding plate 12 that can move forward and backward, and drive the fourth adjusting plate 41 to move through the second sliding plate 32 that can move left and right, so as to form an adjustable PCB board supporting frame, which can adapt to PCB boards of different lengths and widths, and can be adjusted by the first clamping block 24 and the second clamping block 24 with adjustable heights. The block 44 is adapted to PCB boards of different thicknesses. When it is necessary to process PCB boards of various types, the staff can quickly adjust it through the controller 2, and the operation is relatively simple. At the same time, the device can press the edge of the PCB board through the first lower pressing rod 14 and the second lower pressing rod 15, the first upper pressing rod 16 and the second upper pressing rod 17, the third lower pressing rod 34 and the fourth lower pressing rod 35, the third upper pressing rod 36 and the fourth upper pressing rod 37, which can slide against each other, to prevent the PCB board from curling or warping during the processing. It has good anti-curling and anti-warping performance, and can improve the yield rate of PCB board processing.
