Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker processing, in particular to a welding device for circuit breaker leads. Background Art

[0002] At present, the tin soldering process is generally used for welding the circuit breaker leads. The leads are connected to the terminal board of the circuit breaker through the welding process, which can largely avoid the breakage of the leads.

[0003] For example, the welding device for the lead of a circuit breaker with patent number CN217991213U includes a carrier, a wire feeding mechanism and a welding mechanism. The terminal block is limited to the contoured groove on the carrier, and the lead is placed at a preset connection position on the terminal block. The wire feeding mechanism includes a power roller assembly and a position adjustment assembly. The tin soldering wire moves toward the direction of the position adjustment assembly through the power transmission of the power roller assembly to reach the top of the lead. The position adjustment assembly includes an adjustment plate, and the tin soldering wire is passed through the adjustment plate. The above documents still have deficiencies. When in use, the welding mechanism includes an electrode and a welding drive member. The electrode is connected to the driving end of the welding drive member. The welding drive can drive the electrode to move toward the lead and against the tin soldering wire. The electrode heats the tin soldering wire to melt the tin soldering wire to weld the lead to the terminal board. No human intervention is required during the wire feeding and welding process, which is conducive to ensuring the stability of the welding quality. However, the welding device in the above document has a fixed height when in use, and the heights of different workers are different. During welding, it is not convenient to adjust the height of the device according to actual use requirements. At the same time, when the circuit breaker lead is welded, the welding position is exposed to the outside. If the operator does not touch it, it is easy to cause injury to the operator. When in use, the protection of the device is poor. Utility Model Content
