Automatic Silver Dot & Stationary Contact Welding Machine<\/h1>\n

This silver dot contact automatic welding machine has been manufactured to create high precision resistance welds between silver contacts and static (stationary) contact heads. The machine utilizes a servo motor controlled welding pressure system allowing for programmed weld force application precision; medium frequency inverter welding power supply provides stable energy output characteristics; and automatic solder paste dispensing system applies flux or paste to the surfaces to be welded before every weld. The machine is made specifically for mass production of electrical contacts for use in relays, switches and circuit breakers.<\/p>\n

This setup is designed to use two separate vibratory feed systems (one for feeding silver dots to be welded, and another for feeding stationary contacts to be welded) and automatically feed components to the designated welding locations. The user-friendly design is such that the operator only needs to set parameters at the HMI, pour parts into their respective vibratory feeders, press start to begin operation, and the machine is completely automated and will discharge parts either via an exit conveyor or collection bin at the end of the cycle.<\/p>\n

The welding pressure is controlled by servos ensuring consistent strength and flash when joining parts. Medium frequency welding technology is superior for the production of repeatable welds at a fast pace with reduced electrode wear.<\/p>\n

What is a Silver Dot & Stationary Contact Automatic Welding Machine?<\/h2>\n

A silver dot contact automatic welding machine is a specialized resistance welding machine that is used to attach a small silver alloy contact (silver dot) to a fixed contact terminal (static contact head). This assembly is essential in low\u2011voltage switching devices such as relays, contactors and circuit breakers since low contact resistance and high mechanical strength are necessary. The machine utilizes a medium frequence inverter power supply (typically 1,000\u20134,000 Hz) to produce an accurate welding pulse. The welding head is driven by a servo motor, so programmable force profile options (i.e., soft touch, high force, dwell) are available. An optional automatic solder paste dispenser applies flux or paste to the welding interface for improved wetting and reduced oxidation. The machine can be fed by either vibratory bowls or tape feeders and is able to continuously run in an unattended mode. As this is a non-standard custom solution, we will design the electrode geometry, fixture design and feeding system specifically for your silver dot and contact dimensions.<\/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> The HMI and the operator determine the applicable welding parameters (e.g., force, energy, time, and paste volume) for the specific type of product based upon the specification requirements provided for that product.<\/li>\n
  2. Component loading<\/strong> \u2013 Operator pours silver dots and stationary contacts into their respective vibratory feeders.<\/li>\n
  3. Start<\/strong> \u2013 Operator presses the start button; the machine begins automatic operation.<\/li>\n
  4. Feeding & orientation<\/strong> \u2013 Feeders orient and separate components; they will either be presented for pick-and-place by the operator or will slide into a welding nest for support.<\/li>\n
  5. Solder paste application (optional)<\/strong> \u2013 A dispenser applies a precise amount of flux\/paste to the welding interface.<\/li>\n
  6. Component placement<\/strong> \u2013 The silver dot is placed onto the stationary contact (or vice versa) in the welding electrode.<\/li>\n
  7. Welding<\/strong> \u2013 Servo motor applies programmed force; medium\u2011frequency power supply delivers welding pulse.<\/li>\n
  8. \ud488\uc9c8 \ubaa8\ub2c8\ud130\ub9c1<\/strong> \u2013 Optional weld energy and displacement monitoring; rejects detected.<\/li>\n
  9. Unloading<\/strong> \u2013 Finished assembly is ejected into a collection bin or onto an exit conveyor.<\/li>\n
  10. Cycle repeats<\/strong> \u2013 Continuous automatic production.<\/li>\n<\/ol><\/div>\n

    Servo\u2011controlled welding pressure<\/h4>\n

    Unlike pneumatic systems, servo pressure provides precise, programmable force profiles (e.g., pre\u2011press to avoid part movement, then high force during weld, then hold pressure). This eliminates impact bounce and ensures consistent joint strength.\n <\/p><\/div>\n

    \n

    Medium\u2011frequency inverter welding<\/h4>\n

    MFDC (medium\u2011frequency direct current) offers fast rise time (less than 1ms) and constant current output, independent of line voltage fluctuations. Results in less spatter, lower electrode wear, and better weld consistency than AC or capacitive discharge.\n <\/p><\/div>\n

    \n

    Automatic solder paste dispensing<\/h4>\n

    Pre\u2011applying flux or paste to the silver\u2011to\u2011copper interface improves wetting, reduces oxidation, and lowers required welding energy \u2013 especially important for silver alloys with high contact resistance.\n <\/p><\/div>\n

    \n

    Dual feeder flexibility<\/h4>\n

    The machine can handle a wide range of silver dot sizes (1\u20118mm diameter) and stationary contact shapes. Quick\u2011change tooling allows changeover between product families in under 20 minutes.\n <\/p><\/div>\n<\/p><\/div>\n

    An automotive relay manufacturer needed to join silver-tin oxide contacts to brass fixed terminals. The company produced 2,500 assemblies each shift. The previous pneumatic welding system produced inconsistent forces and electrodes often wore out quickly. By upgrading their production process with our fully automatic silver dot welder with servo control and MFDC technology, the manufacturer has experienced the following benefits:<\/p>\n

    \n
    0.1%<\/strong> Weld defect rate (down from 1.5%)<\/div>\n
    2\u00d7<\/strong> Electrode life (from 5,000 to 10,000 welds)<\/div>\n
