Voice Coil Motor Laser Welding Machine

VCM Laser Welder for Precision Welding

Voice coil motor laser welding machine adopts intelligent platform, cooperate with high-precision CCD positioning and monitoring system to weld electronic parts and other precision parts. For some heat sensitive or soft plate connection areas, it can effectively ensure the welding accuracy and welding effect, and avoid burns.

VCM Voice Coil Motor Laser Precision Welding System

This voice coil motor  laser welding machine with simple operation is able to realize the function of high speed operation. In addition, it is compatible with various kinds of design software, including Autocad, Coredraw, Wentai carving, Photoshop and so on.

The solder joints in voice coil motor components are small in size and difficult to observe with the naked eye. The smallest spot of laser soldering can be 50 microns or less, and the spot shape can be designed to be round, square and other special shapes.

Advantages of  Laser Welding Voice Coil Motor Parts:

  • Its precision ensures accurate joining of small components, crucial for intricate devices.
  • The minimal heat-affected zone (HAZ) reduces the risk of damage to sensitive parts.
  • Laser welding is a fast and efficient process, contributing to increased productivity and cost-effectiveness.
  • The non-contact nature minimizes the risk of mechanical damage, ensuring the longevity of the motor.
  • Clean and aesthetically pleasing welds, along with versatility in material compatibility, make laser welding suitable for various applications.
  • Integration into automated processes enhances efficiency, and reduced distortion is critical for optimal voice coil motor performance.

Motor automated laser welder is a kind of laser welding equipment that couples high-energy laser beam into optical fiber, after fiber transmission, collimates into parallel light through collimator, and then focuses on the workpiece for welding. With the laser welding head to implement flexible transmission non-contact welding, it has greater flexibility.
