Process:
The foil roll is introduced into the rubber roller of the feeding device via the decoiling machine and then would in the winding former after passing through the edge of the shearing machine and the roller wheel of the burr pressing device. The inter layer insulation coil is erected in the rear of the coiling optical shaft of the foil winding machine and wound in the winding former after sheared by the trimming roll and the shears blade.
Functional feature:
1. The device adopts and electrical servo deflection correction system to achieve manual/automatic adjustment of the foil position more conveniently and reliably.
2. An advanced electrical control technology of constant tension is adopted to control the tension of the foil and the inter layer insulation, with the features such as quantitive, accurate and convenient control of the tension no mechanical friction. The required tension can be maintained for forward winding, stop and backward winding, ensuring compact coils.
3. The inter layer insulation adopts a cantilever mechanism, convenient for feeding and the mechanism can be pulled out as a whole without guide rails outside the body.
4. Automatic welding mechanism and roll shearing mechanism adopt ball screws and linear guide rails for drive, ensuring the service life and accuracy of the device.
5. This device first adopts the all-in-one sing frame, solving problems such as few coil urns and deflection correction lag.
6. This device is a hi-tech product produced by combining with actual production on the basis of many similar products at home and abroad. The whole machine is controlled via an advanced PLC touch screen, with high automation level and simple and reliable operation, representing higher production level of domestic foil winding machines.

LED production capacity is tightening, domestic giants are down
After a round of cruel baptism, the LED industry boom in 2014 surpassed last year and revived. According to the latest data from IHS, this year will be an optimistic year for China's LED market. LED chip revenue will reach US$1.475 billion, up 36.6%, and packaged LED revenue will reach US$4.812 billion, up 14.8%. The agency expects the share of China's general lighting in all applications will increase from 49.1% in 2013 to 51.6% in 2014. The LED industry's production capacity is “tightly balancedâ€. The development of the industrial chain reflects the large-scale popularization of LED lighting in the next 3 to 5 years. The industry's production capacity will move from a small surplus to a tight balance, and the price will stabilize. It will realize the true LED lighting revolution. Since the second quarter of 2013, the downstream LED lighting market demand exceeded the expected scale, directly driving the mid-stream device packaging and upstream chip, epitaxial wafer capacity release and utilization, and the trend of LED boom is further established. In the field of upstream LED chips, according to Mr. Bian Difei, vice president of Huacan Optoelectronics, the downstream market demand is relatively strong. At the end of 2013, the number of MOCVD has increased to 71 units, and 37 MOCVD equipments in Wuhan base have remained at full capacity. However, since the 32 units of Huacan Suzhou Company are still in the commissioning stage, the real contribution is estimated to be in the late first quarter of 2014. For the packaging field, since 2010, the LED industry has experienced the process of “investment heat†and “overcapacity†until the “recovery†in 2013. It is understood that LED capacity utilization rate reached more than 80% last year. For the new round of capacity expansion, Ruifeng Optoelectronics Chairman Gong Weibin has his own unique views. He pointed out that the reason why China's LED packaging manufacturers accelerated their expansion is because they only stayed in the market for only two or three years. Everyone hopes to increase market share by increasing production capacity. In 2013, LED lighting is undoubtedly the most beautiful part of the entire LED industry chain. Whether it is Philips, Osram or domestic listed companies involved in LED lighting, they have delivered brilliant transcripts. At the same time, in the first two months of 2014, the sales of LED lighting products of some enterprises surged year-on-year, showing the characteristics of the off-season. Domestic LED giants took the spring breeze layout in 2014. With this round of LED lighting market heating up, domestic LED companies have also made great gains. Hongli Optoelectronics' net profit increased by nearly 20% last year. The company said that the LED lighting market demanded good and effectively released the company's production capacity, and its main business maintained steady growth. At the same time, the performance of the LED lighting project undertaken gradually showed positive results. Impact. Dehao Runda is optimistic about 2014, and recently announced that the overall sales revenue in 2014 is expected to increase by about 50% compared with 2013. The sales revenue of LED business is expected to increase by about 100% compared with 2013, the amount is about 3 billion yuan, LED business The main reason for the increase is that the market demand for LED general lighting will be better in 2014. Some mid-upstream companies have also begun to extend to the downstream lighting sector. Wanrun Technology, which is engaged in LED packaging business, has entered the downstream lighting field since the second quarter of last year. The company's 2013 annual report shows that the company's LED lighting products achieved operating income of 120 million yuan, a year-on-year increase of 28.91%, and LED lighting products' gross profit margin reached 43.34%. . Packaging manufacturer Ruifeng Optoelectronics also saw the opportunity of LED lighting. The company said that on the basis of stabilizing the LED LCD TV market, it has increased its efforts in the field of LED lighting and achieved corresponding growth in sales and profits. Xiamen Xinda Company won the first prize in the spring of 2014, and its application for private placement was approved by the China Securities Regulatory Commission. However, in order to expand the trend, some companies will sacrifice their short-term profit margins and have a long-term layout. For example, Qinshang Optoelectronics' net profit declined last year because the company vigorously laid out a global channel network in 2013 and increased advertising investment, resulting in increased costs.
