Embodiment Construction

[0046] Such as figure 1 As shown, the assembly welding object of the present invention is the electromagnetic assembly 45 applied in the low-voltage circuit breaker. Its structure is to include the oil cup 14. The outer circumference of the oil cup 14 is sequentially set with a multi-layer annular paper lower gasket 15 (2 in total), a coil 16 with a soft connection, a multi-layer annular paper upper gasket 17, and an inverted L-shaped gasket. The magnetic yoke 18 of the structure forms a weld seam 107 with a triangular cross-section after soldering, the maximum thickness of the weld seam 107 is 2 mm, and the extension length of the weld seam 107 is not less than 1 / 3 circle along the circumference.

[0047] The function of the welding system of the present invention is to automatically assemble and weld together the oil cup 14, the lower gasket 15, the coil 16, the upper gasket 17 and the yoke 18 of the above-mentioned single components to prepare an integrated electromagnetic ...

Abstract

The invention discloses a full-automatic welding system of an electromagnetic assembly of a low-voltage circuit breaker. The system comprises a rotary disc arranged on a horizontal table top. Eight clamp assemblies are uniformly arranged along the circumference close to the outer edge of the rotary disc, and an indexing mechanism is arranged on the lower surface of the rotary disc; eight mechanisms are successively arranged around the periphery of rotary disc on the horizontal table top; the eight clamp assemblies are uniformly distributed as eight rotating stations which are successively an oil cup loading station, a lower gasket loading station, a magnet yoke loading and storing station, a coil loading station, an upper gasket loading station, a magnet yoke loading station, a tin solder station and a discharging station. A product taking mechanism is arranged on the outer side of the discharging station. The invention also discloses a welding method of the electromagnetic assembly of the low-voltage circuit breaker. The device and method disclosed by the invention are compact in structure, reliable to work and high in welding quality.

Description

technical field [0001] The invention belongs to the technical field of assembly and welding of electrical components, and relates to a fully automatic welding system for electromagnetic components of a low-voltage circuit breaker, and also relates to a fully automatic welding method for electromagnetic components of a low-voltage circuit breaker. Background technique [0002] Electromagnetic components of low-voltage circuit breakers are key components in low-voltage molded case circuit breakers. The electromagnetic components composed of oil cups, yokes, and coils have the characteristics of long oil damping, strong anti-interference, high withstand voltage, long delay, delay and instant reliability. It has the advantages of high durability and many times of recycling. [0003] The existing soldering is mainly spot welding and linear drag welding. For the assembly and welding of the oil cup and the yoke components, or the small size oil cup and the yoke coil of the arc weld...
