In electroplating trade, when electroplating the metal level of corresponding thickness to the operation electroplating of circuit board through the plating bath, need utilize anchor clamps centre gripping to be connected with a plurality of clamping jaws of arranging along circuit board width direction interval in hanger second side and anchor clamps first through the clamping jaw fixed plate, utilize the clamping jaw to carry out the centre gripping fixed to the first end of panel, with the circuit board unsettled in corresponding plating bath to go up unloading opening clamp mechanism through conveying mechanism drive and remove in order to drive the circuit board electroplate in the plating bath of different functions. During electroplating, the cathode current is guided to the clamping jaw fixing plate from the conducting plate, then the current is guided to the clamping jaw from the clamping jaw fixing plate, and the charged clamping jaw provides the cathode for the circuit board, so that the charged circuit board reacts with metal cations in the electroplating bath to complete electroplating.

In order to ensure the stability of clamping and the verticality of the circuit board in the electroplating bath and the electroplating quality, the middle and two ends of the upper edge of the circuit board are fixed by clamping jaws, and the clamping jaws are electrically connected with a clamping jaw fixing plate. But the circuit board of different thickness often need electroplate in the electroplating, to the great circuit board of thickness, because the intensity of circuit board self is higher, through the first clamping jaw of the anchor clamps clamp of the first side of circuit board upper edge of circuit board, utilize anchor clamps and circuit board self gravity to make the circuit board can keep better straightness that hangs down. However, for a circuit board with a small thickness, especially a thin plate with a thickness less than 0.3mm, the strength of the circuit board is not enough to ensure the verticality of the plate surface, and if the upper edge of the thin plate is clamped only by the clamp of the first side of the thin plate, the second end of the thin plate is easy to shake, warp, tear, stack and the like, so that the plating layer is not uniform, and the electroplating quality of the circuit board is affected.

However, the clamp opening device with the above structure cannot meet the requirement of feeding and discharging of a newly developed clamping and fixing mechanism with an adjustable frame structure, which is enclosed by a clamp, a material clamp and a first connecting piece, and the clamp opening device with the above structure can only open the clamp for feeding and discharging of a frameless clamping and fixing mechanism and a clamping and fixing mechanism with an unadjustable frame structure, that is, can only open the clamp for feeding and discharging of a sheet with a fixed size, and cannot automatically adjust the clamping and fixing mechanism with an adjustable frame structure on line.
