      For the placement machine, improve the efficiency of the chip executive will be the direction of the field of research, voice coil motor is one of the options. Application of voice coil motor can achieve higher speed, wider scope of application, better performance of the chip executive.
      So what is the voice coil motor ? The voice coil motor is a special form of direct drive motor that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate transfer mechanism. The principle is: in a uniform air gap into a cylindrical winding, winding power generated by the electromagnetic force to drive the load for the linear reciprocating motion, change the strength and polarity of the current, you can change the size and direction of electromagnetic force. So the form of the voice coil motor can be straight or rotated. It has the advantages of high response, high speed, high acceleration, simple structure, small volume, good force characteristics and convenient control.
      voice coil motor in the patch process needs to complete the action has three main parts: pick up, rotate and place. Pick up and rotate the action only need to move the target location requirements, voice coil motor pick up, rotate the two movements are repeated movement. Chip placement is the most critical part of the entire patch process. To ensure the reliability of the patch, the link not only requires high-precision position control, but also the voice coil motor linear shaft output force control, that is, force / bit mixing control. In order to realize the soft landing of the voice coil motor, the latter can effectively realize the soft landing control of the voice coil motor, and in the aspects of parameter setting, program preparation and trajectory observation, etc., in the control mode of the voice coil motor, Relative to the former more advantages.
      In addition to the application of the patch coil, it also has the following applications: semiconductor, optical electronics, automotive production testing, biological biochemical detection sampling, food and pharmaceutical, assembly packaging, automated testing, high-speed scanning, digital imaging systems, Welding, patching, assembly, testing and inspection equipment, the handling and detection of optical components, a variety of linear or rotary applications, precision and high-speed sports equipment, especially the need for high-speed cycle of reciprocating applications.
      Kunshan Tongmao Electronics Co., Ltd., is a set of linear motor technology research and development, linear motor, voice coil motor, precision linear platform and marketing as one of the manufacturers.
