Tension Controller Apply In Solar Energy

Multi-wire cutting technology (MWS: Multi-Wire-Slicen) is an innovative process for cutting brittle hard materials such as silicon ingots. It is a new type of cutting processing method in which a high-speed reciprocating motion of a wire is carried into a semiconductor processing region for grinding, and a hard and brittle material such as a semiconductor is simultaneously cut into hundreds of sheets at a time. High-precision CNC multi-line high-speed cutting machine based on high-precision high-speed and low-cost cutting control technology can fully realize high-precision, high-speed, low-loss cutting of semiconductor materials and various hard and brittle materials, and has gradually replaced the traditional The inner circle is the main way to cut the silicon wafer.

Multi-wire cutting technology can be used to cut brittle hard materials such as silicon ingots, and can also be used to separate difficult-to-cut materials. This process has the following advantages:

(1) high economic efficiency, can cut hundreds of wafers at a time; 

(2) can cut silicon ingots up to 300mm in diameter;

(3) The crystal defect depth is small;

(4) Less geometric defects (TTV, bow, deviation, etc.); 

(5) Suitable for dividing hard and brittle or difficult to cut materials;

(6) The loss rate is low and the division error is small.

For web tension controllers, the synchronous control of the spindle servo and the take-up and reel and the tension control between the wires are always the key points of such mechanical control. The tension controller, which connects multiple sets of servos via the EtherCAT bus, is the perfect combination for synchronizing control.

The tension controller is mainly composed of three parts: machine tool, numerical control system and high frequency power supply. The numerical control system is composed of single-chip microcomputer, keyboard and frequency conversion detection system, and has main functions such as gap compensation, linear interpolation, circular interpolation and automatic wire breaking. The machine tool consists of a bed, a wire storage mechanism, a wire frame, an XY table, a fuel tank and the like. The wire wound around the storage drum is reciprocated at a high speed through a wire frame. The machined workpiece is fixed on the XY table. The movements in both X and Y directions are controlled by a stepper motor. Each time the CNC system sends a signal, the stepper motor takes a step and drives the two-direction screw to rotate through the intermediate transmission mechanism, respectively, so that the X and Y tables are fed.

The multi-tension controller has high requirements on the reliability and real-time performance of the control system. To ensure the processing quality, it is necessary to control the tension of the steel wire during the cutting process. Accurately controlling the tension value and reducing the fluctuation of the tension is a key technology of the multi-tension controller, which is of great significance for improving the processing quality and the continuous line in the cutting process and improving the reliability of the equipment. In this project, the tension controller is used to connect multiple sets of servos through the EtherCAT bus for synchronous control, which effectively reduces the fluctuation of tension.

SYSMACNJ series machine controller is the latest generation of machine automation controller. It has unparalleled high speed and reliability. It integrates motion, logic and visual control. It has interpolation function and electronic gears such as straight line and circular arc. Synchronous action function of electronic gears, synchronization and tension adjustment through electronic gear FB, high-speed operation of minimum 500μs can be performed, and motion control of 4 to 64 axes can be realized. In particular, the built-in EtherNet/IP and EtherCAT master stations enable high-speed control of the network. The SYSMACSTUDIO and MC function axis setting functions make the servo axis setting very simple. The EtherCAT network servo used in the system, with the highest level of performance in the industry, helps users to effectively reduce production tact time.

In this system, the tension controller connects multiple sets of servos via the EtherCAT bus, forming the best combination for solving synchronous control. EtherCAT uses a distributed clock mechanism to guarantee synchronization between the axes with a refresh time of 100μs and a time base error of no more than 1μs, making it the fastest network on the market. In addition, NJ501's programming software SYSMACSTUDIO can complete the configuration of controllers, networks, servos and other field devices through simple settings, complete complex motion control through internal function blocks, and utilize advanced order and The motion control simulation function pre-tests the motion trajectory in the 3D environment, shortening the engineer's repeated debugging time in the field, and greatly improving the productivity based on the operation of the variable.
