[0035] The utility model embodiment provides a kind of wire bonding protection assembly, refer to Figure 1 、 Figure 2 And Figure 3 , the wire bonding protection assembly includes first anti-static plate 1, second anti-static plate 2, partition column 3 and blow nozzle 4;First anti-static plate 1 and second anti-static plate 2 are two oppositely arranged wire passing plates;Partition column 3 is arranged between first anti-static plate 1 and second anti-static plate 2, so that first anti-static plate 1 and second anti-static plate 2 cooperate to form protection space for the wire passing;Partition column 3 is used to support the wire passing in protection space;Blow nozzle 4 is installed on first anti-static plate 1 and / or second anti-static plate 2, for blowing in protection space.

[0036] As an example, the wire protection assembly is used to protect the welding wire and avoid the welding wire from being contaminated. The wire protection assembly comprises a first anti-static plate 1, a second anti-static plate 2, a partition column 3 and a blowing nozzle 4. When installed, the first anti-static plate 1 and the second anti-static plate 2 are arranged oppositely, and the partition column 3 is arranged between the first anti-static plate 1 and the second anti-static plate 2, so that the first anti-static plate 1 and the second anti-static plate 2 cooperate to form a protection space for the welding wire to pass through. The partition column 3 is used to support the welding wire passing through the protection space, so as to avoid the welding wire from being blown out of the protection space.

[0037] The conventional wire passing plate is subjected to electroplating surface treatment, so that a relatively thick metal protective plating layer is attached to the surface of the wire passing plate. The electroplating layer makes the wire passing plate have wear resistance, but causes static electricity accumulation. When the workpiece is used for a period of time, the accumulated static electricity reaches a certain voltage to form a power source. When the distance between the welding wire and the workpiece is reduced to a certain extent, a discharge gap is formed, which causes the local melting or vaporization of the metal on the surface of the workpiece, thereby affecting the service life of the workpiece.

When the size of the first anti-static plate 1 is smaller than the size of the second anti-static plate 2, the blowing nozzle 4 is installed on the second anti-static plate 2. When the size of the first anti-static plate 1 is equal to the size of the second anti-static plate 2, the blowing nozzle 4 is installed on both the first anti-static plate 1 and the second anti-static plate 2. The air inlet grooves 18 are arranged on both the first anti-static plate 1 and the second anti-static plate 2, and the air inlet grooves 18 on the two anti-static plates cooperate to form an air inlet channel which faces the protection space. The air outlet of the blowing nozzle 4 is communicated with the air inlet channel and faces the protection space, and the blowing nozzle 4 blows air into the protection space. When the wire feeding mechanism feeds the wire, the welding wire passes through the protection space, and the gas supports the welding wire to achieve the protection of the welding wire, so as to avoid the welding wire from being contaminated and ensure the quality of the welding wire.
