[0015] A processing technology for copper-based surface palladium-plated bonding wires, using the above-mentioned processing equipment for copper-based surface palladium-plated bonding wires, includes the following steps:

[0016] S1: When heat-treating the bonding wire, protective gas is introduced into the heating chamber through the gas supply valve. Then, the bonding wire enters the rotating tube through the feed port. The bonding wire is located between two rubber rollers. At this time, under the action of the third spring, the two rubber rollers are pressed against each other for sealing. At the same time, under the sealing operation of the moving plate, the tightness of the feed port and the discharge port can be ensured, thereby avoiding the escape of protective gas and heat, being more energy-saving and environmentally friendly, and ensuring the heating efficiency and effect. Moreover, when heating, the motor is started. The rotation of the motor drives the rotation of the rotating shaft, thereby driving the rotation of the rubber rollers, and further driving the conveyance of the bonding wire.

[0017] S2: At the same time, the electric heating plate is started for heating. And the blower is started, so that the hot air in the heating chamber enters the connecting tube through the extraction duct, and after passing through the blower and the blowing tube, blows on the surface of the bonding wire. Thus, before the bonding wire enters the rotating tube, preheating treatment can be performed on it, improving the heating efficiency and effect. The heated bonding wire can be kept warm in the rotating tube and then enters the cooling chamber through the discharge port for cooling operation.

[0018] S3: When heating, when the hot air enters the fixed box through the blowing tube, it can impact on the surface of the baffle, causing the rotating rod to rotate. When the rotating rod rotates, it drives the gear to rotate, thereby driving the toothed ring and the rotating tube to rotate, and further driving the moving plate and the electric heating plate to rotate, making the heating more uniform and ensuring the heating efficiency and quality.

[0019] S4: Also, the lifting module drives the moving rod and the second pushing block to move downward. When the second inclined surface abuts against the side wall of the moving ring, it can push the moving ring to move away from the second connecting block. At the same time, the second spring is stretched. When the moving ring moves, it drives the first pushing block to move synchronously. When the first inclined surface abuts against the end of the push rod, it can push the plurality of moving plates to move closer to each other. At the same time, the first spring is compressed, thus facilitating the adjustment and control of the heating distance between the electric heating plate and the bonding wire, and improving the heating efficiency and effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1)The processing equipment and processing technology of the copper-based surface palladium-plated bonding wire, by setting a circulation mechanism, etc., when heat-treating the bonding wire, introduce a protective gas into the heating box through a gas supply valve. Then, the bonding wire enters the rotating tube through the feeding port. At the same time, start the electric heating plate for heating. And start the fan, so that the hot air in the heating box enters the connecting tube through the exhaust duct, and blows on the surface of the bonding wire after passing through the fan and the blowing pipe. Thus, before the bonding wire enters the rotating tube, it can be preheated, which can improve the heating efficiency and effect. The heated bonding wire can be kept warm in the rotating tube, and after heat preservation, it enters the cooling box through the discharging port for cooling operation.

[0022] (2)The processing equipment and processing technology of the copper-based surface palladium-plated bonding wire, by setting a driving mechanism and a first pushing mechanism, etc., when heating, when the hot air enters the fixed box through the blowing pipe, it can impact on the surface of the baffle, causing the rotating rod to rotate. When the rotating rod rotates, it drives the gear to rotate, thereby driving the gear ring and the rotating tube to rotate, and further driving the moving plate and the electric heating plate to rotate, so that the heating is more uniform, ensuring the heating efficiency and quality. And, drive the moving rod and the second pushing block to move downward through the lifting module. When the second inclined surface abuts against the side wall of the moving ring, it can push the moving ring to move away from the second connecting block. At the same time, the second spring is stretched. When the moving ring moves, it drives the first pushing block to move synchronously. When the first inclined surface abuts against the end of the pushing rod, it can push a plurality of moving plates to move closer to each other. At the same time, the first spring is compressed. Thus, it is convenient to adjust and control the heating distance of the electric heating plate to the bonding wire, and can improve the heating efficiency and effect.

[0023] (3)The processing equipment and processing technology of the copper-based surface palladium-plated bonding wire, by setting a reset component and a driving mechanism, etc., when heating, the bonding wire is between two rubber rollers. At this time, under the action of the third spring, the two rubber rollers abut against each other for sealing. At the same time, under the sealing operation of the moving plate, the tightness of the feeding port and the discharging port can be ensured, so as to avoid the escape of the protective gas and heat, which is more energy-saving and environmentally friendly, and ensure the heating efficiency and effect. And, when heating, start the motor, the rotation of the motor drives the rotation of the rotating shaft, thereby driving the rotation of the rubber rollers, and further driving the conveying of the bonding wire.

The side wall of the fixed block (901) is fixedly connected to a motor (903), and the output end of the motor (903) is fixed to one end of the rotating shaft (902).

8. A process for processing a copper-based surface palladium-plated bonding wire, using the processing equipment for processing a copper-based surface palladium-plated bonding wire as claimed in claim 7, characterized in that: The following steps are involved: S1: When heat treating the bonding wire, protective gas is introduced into the heating box (10) through the gas supply valve (101), and then the bonding wire is passed through the feed port (13) into the rotating tube (12), and the bonding wire is located between the two rubber rollers (16). At this time, under the action of the third spring (803), the two rubber rollers (16) are sealed against each other. At the same time, under the sealing operation of the first movable plate, the sealing of the feed port (13) and the discharge port (14) can be ensured, thereby preventing the escape of protective gas and heat. In addition, when heating is performed, the motor (903) is started, and the rotation of the motor (903) drives the rotation of the rotating shaft (902), thereby driving the rotation of the rubber roller (16), and further driving the conveying of the bonding wire; S2: At the same time, the electric heating plate (18) is started for heating, and the fan (1901) is started, so that the hot air in the heating box (10) enters the connecting pipe (1902) through the exhaust pipe (1904), and blows onto the surface of the bonding wire after passing through the fan (1901) and the blowing pipe (1903), so that the bonding wire can be preheated before entering the rotating tube (12). The heated bonding wire can be kept warm in the rotating tube (12), and after being kept warm, it enters the cooling box (20) through the discharge port (14) for cooling; S3: When heating is performed, when hot air enters the fixed box (701) through the air blowing pipe (1903), it can impact the surface of the baffle (703), causing the rotating rod (702) to rotate. When the rotating rod (702) rotates, it drives the gear (602) to rotate, thereby driving the ring gear (601) and the rotating tube (12) to rotate, and further driving the second movable plate and the electric heating plate (18) to rotate; S4: Furthermore, the lifting module (501) drives the moving rod (502) and the second pushing block (503) to move downward. When the second inclined surface (504) abuts against the side wall of the moving ring (301), the moving ring (301) can be pushed to move in a direction away from the second connecting block (403). At the same time, the second spring (404) is stretched. When the moving ring (301) moves, the first pushing block (303) is driven to move synchronously. When the first inclined surface (304) abuts against the end of the pushing rod (302), multiple second moving plates can be pushed to move closer to each other. At the same time, the first spring (203) is compressed, so as to facilitate the adjustment and control of the heating distance of the electric heating plate (18) on the bonding wire.
