Delta Strengthens Motion Control with Its Horizontal Hook Winding Machine Solution
Cables and wires are both extremely common and an indispensable part of our daily lives. Charging cables, internet cables, electrical wires and the like, are basically everywhere. We even see a variety of gadgets invented just to tidy up the tangling cords. While it’s not impossible to live without these messy cords, when it comes to industrial wires and cables, which often run more than dozens or even hundreds of meters, it would be another story—one we will tell today.
In many industries, wires and filaments must be wound uniformly in different directions, patterns and spread widths. For example, yarns for the textile industry, copper wires for inductance coils, and voice coils for speakers—they all bear very different characteristics when it comes to winding. As a result, winding machines are developed to carry out the task quickly and precisely. Applied to wires of different thickness, weights and properties, winding machines may be one of the most highly varied industrial devices. Some are specialized for certain products such as inductance coils and motors, and some serve for certain patterns or directions, such as vertical and horizontal winding machines.
Among the various types, the horizontal hook winding machine plays an important role in the production of electrical tools, including hand drills, hair dryers, vacuum cleaners and electric saws. This type of winding machine is composed of reciprocating and indexing axes. Take stator windings for example: When the stator is located, a fixture goes into it to start winding. The reciprocating axis enables the hook to move back and forth for wire feeding. Meanwhile, the index axis rotates the reciprocating one for stator wire hooking.
Winding is not just about speed. Other important points include whether the wires are evenly laid and the cable jacket undamaged. Aiming to fulfill the need of precise motion control at high speeds, Delta developed a solution for horizontal hook winding machines for a client in East China. The Delta AC Servo Systems ASDA-M-R and ASDA-A2 Series enable the eCAM function for precise and simultaneous multi-axis movements. Allowing the winding process to be carried out at high speeds without damaging the coating, this mechanism has increased the capacity by 10%. Additionally, the Delta AC Servo System ASDA-M-R Series can work with Delta’s software development platform to serve as an independent primary station for motion control. The platform allows 20 types of programs, and each one supports up to 500 sequences. In addition, the Delta Human-Machine Interface DOP-100 Series allows users to give orders in an intuitive way.
Delta’s horizontal hook winding machine solution offers the following benefits to the client:
• Excellent precision and high speeds achieve consistent quality and better productivity
The eCAM function of the Delta Servo Systems ASDA-M-R and ASDA-A2 Series enables high precision motion control with lower rates of failures. The winding speed reaches 400 turns per minute, providing a high degree of uniformity without damaging the wires.
• Robust motion control satisfies multiple needs of winding
The solution supports Delta’s development platform to manage programming. Twenty types of programs are allowed and each supports up to 500 sequences. The interpolator also enables multi-axis interpolation.
• Flexible management of special turns requirement
Winding parameters are allocated with a set of numbers, and operators can easily manage the number of turns required for different stators.
Winding machines are one of the most widely applied industrial devices, and the performance requirements have been increasing. Among the many winding machine solutions, Delta provides one that achieves excellent motion control at high speeds. Supporting programming, Delta’s solution also provides the flexibility to enhance productivity and quality.
