Usage: First, the manual ring up and down on a flat desktop machine placement, and put on the dial indicator. Then, drill bits and particles placed in the position in Figure 4. Finally, in Figure 3 that is pressed on the ring is completed (dial indicator function is used to mark the location of the drill bits of rubber). The drill bits and particles placed in Figure 5 position. Finally, in Figure 3 that is under pressure to complete the loop. Electronics industry to accelerate toward smaller, denser, faster development of advanced structure installed on automatic Buying ring machine, check the product's early reliance on manual approach has been unable to meet the demand. AOI technology industry draws heavily on the work of auxiliary production loop machine jaws, has become an inevitable trend, such as: electronic assembly AOI performed using solder paste printing, missing parts inspection, contact the state determination, and so the work is familiar practice. Many printing, graphic imaging products, also cited this technology for products with varying degrees of quality checks. Of course, the ring machine manufacturers supply, circuit board production is no exception to refer to these technologies for production tools, finished and semi-finished products inspection, this chapter attempts to sort out the status of the application of these technologies, hoping to give readers as a reference. Manufacturers supply the ring plane, the ring plane, the macro automation provided by the Friends of Lean Lean Automation Co., Ltd. Shenzhen-Hong Friends. Friends of Lean Automation Co., Ltd.
