[Text / high- tech LED reporter Liu Pingping] Multi-wire cutting technology has been the bottleneck of semiconductor material cutting processing in China. To change this situation, Hunan Yujing Machine Co., Ltd. (hereinafter referred to as "Yujing Machine") began in 2000. Committed to the research and development of multi-wire cutting machines.
At present, Yujing Machine has successfully developed multi-line cutting machines of various models such as XQ120A, XQ120B, XQ150 (YB) A and XQ300A. On November 25th, at the 2013 Hi-Tech LED Lighting Exhibition held at Guangzhou Poly Exhibition Hall, Yujing Machine will bring the YJXQ150 (YB) A multi-wire cutting machine to the forefront.
YJXQ150 (YB) A multi-wire cutting machine is a model developed by Yujing Machine for sapphire cutting. It can be used to cut ingots up to 6 inches (including 6 inches). Yang Yuhong, chairman of Yujing Machinery, said that this cutting machine has multiple advantages such as high wire speed, high reliability, high slicing efficiency, high efficiency of cutting line, high positioning and environmental protection.
Since the mechanical size of the wire roller of the multi-wire cutting machine main shaft is small, the requirements for the operator are high during the winding process, and the winding time is long, which affects the production efficiency.
In order to solve the above bottleneck, the YJXQ150 (YB) A multi-wire cutting machine adopts an advanced automatic winding mechanism. When the axis of the wobble coil and the shaft of the processing roller are perpendicular to the cutting line, the winding rod motor starts to drive around. The wire rod wire wheel feeds the distance between the processing roller grooves from the inside to the outside in a winding direction of the processing roller, and slides the cutting line into the wire groove corresponding to the processing roller.
"Circular reciprocating realizes automatic winding function. Precise mechanical positioning technology is required in the control process. The winding rod motor performs 2200 actions, the total accumulated error is less than 0.3mm, the positioning time of each action is 20ms, and the positioning accuracy of the motion control system is The comprehensive speed index has reached the international advanced level.†Qiu Yujun, electrical engineer of Yujing Machinery, said.
In addition, due to the relatively high price of the diamond wire, in order to save the user cost, the YJXQ-150 rocking cutting machine adopts the direct start technology, which eliminates the method of adopting the first low speed preheating and then starting the cutting machine products of other domestic manufacturers, and improves the diamond wire. Utilization rate. At the same time, it provides a variety of flexible disconnection processing methods, adopting the automatic switching technology of the routing direction to realize the true two-way disconnection.
Yang Yuhong said that the performance of the YJXQ150 (YB) A multi-wire cutting machine for sapphire multi-wire cutting can be comparable to that of Japan's high bird. The cutting yield of 2-6 inches sapphire can also be close to that of mainstream imported equipment. At the same time, considering the specific production yield, it also needs to be combined with the processes of various manufacturers. From the feedback data obtained so far, it can basically reach the average level of mainstream equipment in the market.
