[0002] Gold wire welding refers to a method of bonding terminals. The gold wire welding methods can be divided into ball to pressure ring, pressure ring to pressure ring and ball to ball welding. The wire materials are mainly gold, copper and aluminum. The ball to pressure ring welding method is usually carried out by ultrasonic and heating methods. Its working principle is: through the use of ultrasonic friction, under the coordination of pressure and temperature, the gold wire of the solder joint forms a co-crystallization process with the contact surface.

[0003] Welding machine fixtures are often needed in modern welding processes. When welding precision products, they are often not well fixed, and the welding quality is not easy to guarantee. At the same time, the welding quality is poor and the welding efficiency is low. For this reason, we propose a gold wire welding machine base processing quick clamping device to solve the above problems. Utility Model Content

[0006] Furthermore, two reinforcing ribs are provided, which include a vertical surface and a horizontal surface; the horizontal surface is fixed to the base of the gold wire welding machine by screws; and the vertical surface is used for positioning with the vertical side surface of the base of the gold wire welding machine.

[0007] Furthermore, the second positioning pin is vertically arranged on the bottom plate, and cooperates with the positioning hole on the horizontal plane of the base of the gold wire bonding machine for positioning.

[0008] Furthermore, the pressure plate is provided with a waist-shaped hole and a mounting hole; the waist-shaped hole is connected with a clamping screw; the auxiliary support adjustment screw is provided in the mounting hole, and is used to adjust the height of the pressure plate.

[0009] Furthermore, there are three pressing plates, which are respectively arranged on the horizontal plane of the base of the gold wire bonding machine.

[0010] The beneficial effect of the utility model is that by adopting the clamping device, with the cooperation of the reinforcing ribs and the pressing plate, rapid positioning and clamping can be achieved, thereby greatly shortening the clamping time and improving production efficiency.
