A bond wire line cleaning device is designed, including a first retracting spool, a V-shaped sink, a suction fan, a plasma cleaning gun and a second retracting spool arranged from left to right. An ultrasonic cleaning component is provided in the sink. By combining the ultrasonic cleaning component and a plasma cleaning gun, the surface of the bond wire can be quickly cleaned and blow-dried.
The equipment can quickly clean and blow dry the surface of the wired bond wire, improve work efficiency and wire-collection quality, ensure the cleanliness of the surface of the wired bond wire, and quickly close the wired bond wire and clean the active agent residue on the surface of the bond wire.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bonding wire drawing, in particular to a bonding wire take-up and cleaning device. Background Technique
[0002] Generally, a diamond die is used in the bonding wire drawing process, and the metal wire is inserted from one side and passed out from the other side; common non-slip differential devices adopt multi-pass stretching. Through the multi-pass stretching process, the cross-sectional area of the material can be gradually reduced, the ductility of the material can be increased, and the continuous preparation of fine wires can be realized. Such devices usually adopt advanced control systems and process technologies, and can maintain a stable stretching process during high-speed operation.
[0003] The non-slip differential wire drawing device is generally equipped with a corresponding dynamic take-up device, which coordinates with the device speed to achieve uniform and stable speed take-up, and avoids poor wire arrangement.
[0004] The non-slip differential wire drawing device generally has a relatively high speed (>10m / s). Because there is a lot of dirt remaining on the surface, an additional cleaning process needs to be arranged. The traditional ultrasonic water washing device includes a water tank, an air knife and a dryer; generally, the wire is washed in two water tanks, and the residual water droplets on the wire surface are blown off by the air knife, and then dried by the dryer. Limited by the device size, the general cleaning process is relatively slow (0.5-1m / s), and the take-up speed is about 5% of the wire drawing speed. It is not possible to quickly take up the bonding wire after wire drawing in time. If the take-up speed is adjusted, the residual surfactant on the bonding wire surface cannot be removed ideally, so that there is still dirt on the surface of the bonding wire after wire drawing, which does not meet the use standard. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bonding wire take-up and cleaning device to solve the problems raised in the above background technique.

An ultrasonic cleaning component is arranged in the water tank. The bonding wire is wound around the first take-up shaft after being pulled out from the wire drawing mechanism, then passes through the water tank, the suction fan and the hydrogen ion cleaning gun, and is taken up by the second take-up shaft.
[0007] Preferably, the water tank is a long tank with a V-shaped cross-section and a length of 50 cm, and the ultrasonic cleaning component is arranged on its inner tank wall.
[0008] Preferably, the ultrasonic cleaning components are arranged in two groups, and the two groups of ultrasonic cleaning components are respectively arranged on the inner walls on both sides of the water tank.
