[0026] In actual application, the fixed clamp arm 1 is energized, and an upward force is applied to the opening and closing clamp linkage mechanism 12, so that the opening and closing clamp linkage mechanism 12 drives the rotating clamp arm 2 to rotate the movable clamp 3 and the swing arm 10, so that the movable clamp 3 is opened relative to the fixed clamp 5, and the elastic force of the elastic mechanism 9 keeps the movable clamp 3 and the fixed clamp 5 in an open state, the dynamic trigger conductive part 11 is separated from the fixed trigger conductive part 8, and the movable clamp 3 and the fixed clamp 5 are not energized. At this time, the electroplating clamp is in an open clamp and power-off state, and the circuit board can be placed between the movable clamp 3 and the fixed clamp 5; when the circuit board After being placed between the movable clamp 3 and the fixed clamp 5, a downward pressure is applied to the opening and closing clamp linkage mechanism 12, so that the opening and closing clamp linkage mechanism 12 drives the rotating clamp arm 2 to rotate the movable clamp 3 and the swing arm 10 in the opposite direction, so that the movable clamp 3 is closed relative to the fixed clamp 5, and the elastic force of the elastic mechanism 9 keeps the movable clamp 3 and the fixed clamp 5 in a closed state, and the dynamic trigger conductive member 11 contacts and conducts electricity with the fixed trigger conductive member 8, so that the movable clamp 3 and the fixed clamp 5 are energized, and the movable clamp 3 and the fixed clamp 5 clamp the circuit board, and the electroplating clamp is in a closed and energized state. The utility model can realize power off when opening the clamp and power on when closing the clamp, so as to realize synchronous control of opening and closing the clamp and power on and off, thereby improving the safety performance of use, and by arranging the fixed trigger conductive member 8 and the dynamic trigger conductive member 11 on one side of the fixed clamp arm 1, it is convenient for disassembly and maintenance.

[0027] In this embodiment, a first insulating plate 17 is sandwiched between the movable clamp 3 and the rotating clamp arm 2, and a second insulating plate 18 is sandwiched between the fixed clamp 5 and the fixed clamp arm 1.

[0031] In this embodiment, the electroplating clamp that is powered on when closed and powered off when opened further includes a locking plate 22 that is detachably connected to the fixed clamp arm 1. In practical applications, the external power supply sheet is locked to the fixed clamp arm 1 by the locking plate 22 and is electrically connected to the fixed clamp arm 1.

The locking bolt 23 passes through the bottom of the lifting sleeve 6, and the third spring 25 is sleeved outside the locking bolt 23. In practical applications, the locking bolt 23 guides the lifting and lowering of the lifting sleeve 6, and by tightening or loosening the nut 24, the elastic force of the third spring 25 can be adjusted, thereby adjusting the force of the opening and closing clamp.

[0033] In this embodiment, the opening and closing clamp linkage mechanism 12 includes a handle 26 and a connecting arm 27, one end of the handle 26 is connected to a hinge plate 28, one end of the hinge plate 28 is hinged to one end of the rotating clamp arm 2, the other end of the hinge plate 28 is hinged to one end of the connecting arm 27, the other end of the connecting arm 27 is hinged to the top of the lifting sleeve 6, and the middle of the connecting arm 27 is provided with a resisting block 29 for resisting the hinge plate 28; specifically, an insulating sleeve is provided on the outer cover of the handle 26. The opening and closing clamp linkage mechanism 12 belongs to the existing opening and closing clamp control mechanism of the electroplating clamp, which will not be described in detail here, so as to facilitate driving the rotating clamp arm 2 to open or close the movable clamp head 3.

[0034] In this embodiment, the fixed clamp arm 1 is equipped with a limit bolt 30, and the first spring 13 and the limit bolt 30 are respectively located at the front and rear sides of the rotating seat 4; when the movable clamp 3 and the fixed clamp 5 are opened, the limit bolt 30 abuts against the bottom surface of the rotating clamp arm 2 to limit the rotating clamp arm 2 to limit the opening angle of the movable clamp 3 and the fixed clamp 5; when the movable clamp 3 and the fixed clamp 5 are closed, the limit bolt 30 is separated from the rotating clamp arm 2. When it is necessary to adjust the opening angle of the movable clamp 3 and the fixed clamp 5, it is only necessary to screw the limit bolt 30 to adjust the effective limit length of the limit bolt 30.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
