High\u2011Precision Automatic Welding Machine for MCB Bimetallic, Moving Contact & Copper Braid<\/h1>\n

The MCB bimetallic moving contact connector (copper) automatic welding machine (a high-precision automatic assembly machine specifically designed to install the bimetallic connection (the electrical path) in miniature circuit breakers and also install the copper braid connector to create a complete functional mechanism. This machine will weld the bimetallic (moving) contacts onto the moving contact arm and create very low resistance and reliable electrical joints between the moving contact and the copper braid connector; therefore, providing the highest possible electrical performance and durability long-term.<\/p>\n

Features include automatic delivery of copper braids, moving contacts, bimetal strips, and wire cutting are combined with inline quality inspection and welding using several different stations. The production cycle time will be 20 to 22 per minute. The welding process consists of programmable resistance welding (multi-frequency direct current) with computer controlled force and energy. An automatic (pass\/fail) sortation area for rejection of defective assemblies. This machine is perfect for high volume manufacturing of MCBs; reducing the labor cost and variability associated with manual welding. The end result will be consistency in finished products.<\/p>\n

Standard delivery: 45-60 days | Cycle time \u226520 pcs\/min | Resistance or laser welding optional<\/span><\/p>\n<\/p><\/div>\n

What is an MCB Bimetallic, Moving Contact & Copper Braid Automatic Welding Machine?<\/h2>\n

An MCB bimetallic, moving contact, and copper braid automatic welding machine is an automated system that carries out three crucial weld tasks in one process: (1) welding a bimetal strip (thermal trip element) to the moving contact arm, (2) welding the silver-based moving contact to the arm (if not pre-assembled), and (3) welding flexible copper braid to the moving contact assembly. Together, these three welds are all part of the MCB’s main current path. Performing these three welds manually or semi-automatically is slow and can have a lot of variances. The machine automates the full sequence of events; it will feed the components, weld them either with resistance or laser, cut the copper braid to length, check the quality in-line, and sort parts between ‘good’ and ‘bad.’ The net effect is less variability in contact resistance usually (<\/p>\n

Detailed Process Flow (Operator & Machine Sequence)<\/h2>\n
\n

The automated welding process follows these steps:<\/p>\n

    \n
  1. Parameter setup<\/strong> \u2013 Operator sets welding parameters (force, energy, time) on the HMI per product specifications.<\/li>\n
  2. Component loading<\/strong> The operator takes the bimetal strips and moving contacts and pours them into the vibratory feeders. Then they take the copper braid wire coils and put them into the proper rack fixture.<\/li>\n
  3. Automatic wire feeding & cutting<\/strong> The copper braid is automatically supplied to the preset length, and then it is cut to length and loaded into the fixture by the machine itself.<\/li>\n
  4. Bimetal & moving contact feeding<\/strong> – Vibratory bowls separate and orient components of bimetal and moving contacts, then feed them into welding nests for placement and picking.<\/li>\n
  5. Part presence check<\/strong> \u2013 Sensors verify that all components are present before welding; missing parts trigger a reject.<\/li>\n
  6. Automatic positioning & welding<\/strong> – The welding head will take programmed moves to reach the proper position (weld first, then weld second; together = 3 weld heads).<\/li>\n
  7. Quality monitoring<\/strong> The weld energy and displacement are compared to specified curves, and any assembly that is out of tolerance will be classified as reject.<\/li>\n
  8. Sorting & unloading<\/strong> Qualified products are placed onto an exit conveyor or bin with no manual intervention; while rejected products are routed to a separate reject box.<\/li>\n<\/ol><\/div>\n

    Keunggulan Teknis Inti<\/h2>\n
    \n
    \n

    Tri\u2011function integration saves floor space & handling<\/h4>\n

    Instead of three separate machines (bimetal welding, contact welding, copper braid welding), this single station performs all three welds in one cycle \u2013 reducing work\u2011in\u2011progress and operator intervention.\n <\/p><\/div>\n

    \n

    Precision wire cutting & positioning<\/h4>\n

    The copper braid is automatically fed, cut to exact length (\u00b10.5mm), and presented to the welding electrode \u2013 eliminating manual cutting errors and ensuring consistent braid length for each MCB.\n <\/p><\/div>\n

    \n

    Real\u2011time weld quality monitoring<\/h4>\n

    Each weld is monitored for energy, current, and displacement. Out\u2011of\u2011tolerance welds are immediately rejected, preventing defective electrical paths from reaching final assembly.\n <\/p><\/div>\n

    \n

    High throughput with minimal operator attention<\/h4>\n

    At 20\u201122 ppm, the machine replaces 4\u20116 manual welding operators. One operator can load components and monitor multiple machines, drastically reducing labor cost and human variability.\n <\/p><\/div>\n<\/p><\/div>\n

    Customer Success Story \u2013 High\u2011Volume MCB Manufacturer<\/h3>\n

    A Southeast Asian manufacturer of miniature circuit breakers (MCBs) previously used separate stations to weld bimetal strips, move contacts, and connect copper braids together using manual methods. Their defects were 2.5% and could only produce 800 units per shift before the installation of our tri-function automated machine. After installing our automated welding machine, they were able to:<\/p>\n

    \n
    1,200 units\/shift<\/strong> Throughput (50% increase)<\/div>\n
    0.3%<\/strong> Weld defect rate (down from 2.5%)<\/div>\n
    75%<\/strong> Labor cost reduction (replaced 6 operators with 1)<\/div>\n<\/p><\/div>\n

    After 9 months, this apparatus will have recovered its cost and will also have stopped the need for customers to return due to a loose wire (braided copper).<\/p>\n<\/p><\/div>\n
