Continuing the rapid growth in recent years, the industrial robot industry reached a new high in 2017. According to statistics from the market research department of gongkong, in 2017, the sales volume of three kinds of multi-joint, SCARA and parallel industrial robots in China was nearly 90,000 units (sets), a year-on-year increase of more than 40%; sales reached nearly 20 billion yuan, a year-on-year increase of nearly 30%.
Driven by factors such as rigid market demand, favorable policies and the development of robots themselves, gongkong's market research department predicts that the industrial robot market will maintain a strong growth trend in 2018. It is expected that the sales of the above three robots will exceed 20 billion yuan. It is expected to be close to 30 billion yuan in 2020.
From a horizontal perspective, the application fields of industrial robots are mainly concentrated in vehicle/parts manufacturing, electronics and home appliances, metal processing, food, beverage and tobacco and other industries, accounting for about 80% of the market for industrial robots. Among them, the vehicle/parts manufacturing industry, electronics and home appliance industries accounted for the highest proportion.
Especially since last year, with the structural adjustment and expansion of traditional enterprises, robots have shown their talents in the industrial industry, especially in the electronics and home appliance industries, and the demand for industrial robots in this field has skyrocketed. Although the momentum is very fierce, but because the base is quite different from the vehicle/parts manufacturing industry, it does not exceed the market share of the vehicle/parts manufacturing industry.
It is worth mentioning that, thanks to the expansion and extension of the electronics and home appliance industries, small robots suitable for the production of small parts and with a load of less than 20kg have ushered in the spring of development.
Stable product demand structureFrom a vertical perspective, robots such as handling/unloading/palletizing, welding, machining, spraying, etc. are still mainstream models. According to data from the market research department of gongkong, the growth rate of market sales in 2017 has accelerated significantly.
From the perspective of mechanical structure, the market sales of multi-joint, SCARA and parallel robots have achieved a growth of more than 40%. It can be said that the overall sales situation of the industrial robot market is gratifying, and it is moving steadily on the track of rapid growth.
Foreign capital dominates the marketAccording to statistics from the market research department of gongkong, local brands accounted for about 20% of the market in 2017, and foreign brands accounted for about 80%. Compared with the previous year, the sales growth rate of domestic industrial robots was basically stable, and the sales growth rate of foreign brands accelerated significantly.
In the first half of 2018, China's industrial robot market still maintained a strong growth momentum. Headed by the four major international families, ABB, FANUC, Yaskawa Electric, and KUKA, and domestic Estun, Eft, Guang CNC, New Times, and Hyundai Heavy Industries, the two major camps are driving the rapid development of the market.
How does TFT work?
TFT is the abbreviation of "Thin Film Transistor", generally refers to thin film liquid crystal displays, but actually refers to thin film transistors (matrix)-can "actively" control each independent pixel on the screen, which is The origin of the so-called active matrix TFT (active matrix TFT). So how exactly is the image produced? The basic principle is very simple: the Display Screen is composed of many pixels that can emit light of any color, and the purpose can be achieved by controlling each pixel to display the corresponding color. In TFT LCD, backlight technology is generally used. In order to accurately control the color and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the "blinds" are opened, light can pass through, and " When the shutters are closed, light cannot pass through. Of course, technically, it is not as simple as the one just mentioned. LCD (Liquid Crystal Display) utilizes the characteristics of liquid crystals (liquid when heated, and crystallized into solid when cooled). Generally, liquid crystals have three forms:
Smectic liquid crystal similar to clay
Nematic liquid crystal resembling a fine matchstick
Cholestic liquid crystal
The liquid crystal display uses filaments, and when the external environment changes, its molecular structure will also change, and thus have different physical properties-it can achieve the purpose of letting light through or blocking light-which is just like the blinds just now.
Everyone knows the three primary colors, so each pixel on the display screen needs three similar basic components described above to control the three colors of red, green, and blue respectively.
The most commonly used one is twisted nematic TFT LCD (Twisted Nematic TFT LCD). Existing technologies vary greatly, and we will cover them in detail in the second part of this article.
There are grooves on the upper and lower layers. The grooves on the upper layer are arranged longitudinally and the grooves on the lower layer are arranged horizontally. When no voltage is applied to the liquid crystal in its natural state, the light emitted from the light emitting layer of the twisted nematic TFT Display working principle diagram of Figure 2a will be twisted by 90 degrees after passing through the interlayer, so that it can pass through the lower layer smoothly.
When a voltage is applied between the two layers, an electric field is generated. At this time, the liquid crystals are aligned vertically, so the light will not be twisted-the result is that the light cannot pass through the lower layer.
(2) TFT pixel structure: The color filter is divided into red, green, and blue according to the color, which are arranged on the glass substrate to form a group (dot pitch) corresponding to a pixel. Each monochromatic filter is called It is a sub-pixel. In other words, if a TFT display supports a maximum resolution of 1280×1024, then at least 1280×3×1024 sub-pixels and transistors are required. For a 15-inch TFT display (1024×768), then a pixel is about 0.0188 inches (equivalent to 0.30mm), for an 18.1-inch TFT display (1280×1024), it is 0.011 inches (equivalent to 0.28mm) .
As we all know, pixels are decisive for the display. The smaller each pixel is, the larger the maximum resolution that the display can achieve. However, due to the limitation of the physical characteristics of the transistor, the size of each pixel of the TFT at this stage is basically 0.0117 inches (0.297mm), so for a 15-inch display, the maximum resolution is only 1280×1024.
