The most important used SMT machine is pick and place machine. Others include PCB solder paste printing machine, AOI testing equipment, reflow oven and other second-hand SMT equipment. These are automated production equipment. If you operate it slightly wrongly, it will seriously affect the production efficiency of the machine, and may also cause personal safety hazards. Therefore, it is very important to use the used SMT machine correctly. Let me share with you some suggestions!     The core equipment in SMT production line of course is pick and place machine. The fully automatic chip mounter is a device used to realize high-speed and high-precision automatic placement of components. It is the most critical and complicated used SMT machine in the entire SMT production. Used smt pick and place machine has developed from an early low-speed mechanical placement machine to a high-speed optical centering placement machine, and has developed to a multifunctional, flexible connection and modular development. As a high-tech used SMT machine, the safe and correct operation is important to both the machine and people. The most basic thing for the safe operation is that the operator should have the most accurate judgment and should follow the following basic safety rules.     Operators should receive training about the correct method of operation; 1. turn off the power when inspecting the used SMT machine, replacing parts or repairing and internal adjustments (repair of the machine must be performed with the emergency button pressed or power off; 2. make sure YPU (programming unit) is in your hand to stop the machine at any time when “reading the coordinates” and adjusting the machine; make sure that the “interlocking” safety device remains effective to stop the machine at any time, and the safety inspection on the machine cannot be skipped or Otherwise, personal or machine safety accidents are likely to occur; only one operator is allowed to operate a machine during production; 3. during operation, make sure that parts of the body such as hands and head are outside the machine's range of movement; 4. the placement equipment must be correct Grounding; 5. Do not use the patch equipment in a gaseous or extremely dirty environment. The most important point before using the used SMT machine is to receive correct and strict training and to pass the assessment before the machine can be officially operated.

AOI, named as automated optical inspection machine includes multi-light source lighting, high-speed digital cameras, high-speed linear motors, precision mechanical transmission structures, and graphics processing software. During the inspection, the AOI automatically scans the PCB through the camera to capture and image the components or features on the PCB (including the status of printed solder paste, surface mount components, solder joint morphology and defects, etc.) through software processing and pass the database. The parameters are comprehensively compared to determine whether the components and their characteristics are qualified, and then the test conclusions are drawn, such as problems, missing components, bridges or solder joint quality.     The working principle of automated optical inspection machine is the same as that of the vision system used in the pick and place machine and the PCB printing machine. Generally, two methods of Design Rule Checking (DRC) and pattern recognition are adopted. The DRC method checks the circuit pattern according to some given rules (such as all wires should use solder joints as endpoints, all lead widths should be no less than 0.127mm, and the spacing between all leads should be no less than 0.102mm, etc.) This methods can guarantee the correctness of the circuit being tested from the algorithm, and also has the characteristics of easy manufacturing, easy algorithm logic, fast processing speed, small program editing amount, small data occupancy, etc. For this reason, this testing method is often used.   The pattern recognition method compares the stored digitized image with the actual image. During the inspection, the comparison is performed according to an intact printed circuit board or an inspection file established according to the model, or according to the inspection program prepared in the computer-assisted design. The accuracy depends on the split rate and the inspection procedures used. It is generally the same as the electronic test system, but the amount of data collected is large and the real-time data processing requirements are high. The pattern recognition method replaces the established design principles in DRC with actual design data, so it has obvious advantages.     Automated optical inspection machine has functions such as component inspection, PCB light board inspection, and post-weld assembly inspection. The general procedure of automated optical inspection machine system for component inspection is: automatic counting of printed circuit boards with installed components and start inspection; check the leaded side of printed circuit boards to ensure proper arrangement and bending of lead ends; check printed Whether there are missing components, wrong components, damaged components, improper component mounting direction, etc. on the front side of the circuit board; check the type, direction, and position of the IC and discrete components connected; check the components marked on the IC components Printing quality inspection, etc. Once the AOI finds a defective component, the system sends a signal to the operator or triggers the actuator to automatically remove the defective component. The system analyzes defects, provides defect types and frequencies to the host computer, and makes necessary adjustments to the manufacturing process. The efficiency and reliability of automated optical inspection machine depends on the integrity of the software used. AO also has the advantages of convenient use, easy adjustment, and no need to program vision system algorithms.   The above is the automated optical inspection machine (AOI), which uses high-speed and high-precision visual processing technology to automatically detect various mounting errors and soldering defects on the PCB. The PCB can range from fine-pitch high-density boards to low-density large-size boards, and can provide online inspection solutions to improve production efficiency and welding quality.

Today we will share Features of JUKI pick and place machine: In addition to supporting IC or complex shaped heterosexual components, one machine also has high-speed placement capabilities for small components. At present, multifunctional equipment is favored in China. In this era of processing, no one can do everything. In order to survive, whether it is LED or PCB patch, it will be undertaken. Therefore, multifunctional equipment in the patch field has become the key.     JUKI pick and place machine has a strong ability to identify the deviation of the component: laser recognition mainly captures the shape of the component from the front side, which can reduce the influence of unstable factors such as the electrode shape and color of the chip component and ensure a stable high Identification of accuracy.   Reduce defective rate: Use component inspection function to improve placement quality: use laser recognition to monitor the suction of components through the screen before placement, which can prevent the defective placement of small components that cannot be identified by air pressure. Advanced post-placement component inspection and stand-up inspection functions reduce bad mounting.   Image recognition: JUKI's original component recognition system uses both laser recognition and image recognition (reflection recognition, transmission recognition)     A. Corresponding ability: 1. Image recognition technology: Depending on the shape, size, and material properties of the component, a laser recognition system suitable for high-speed placement of chip components and image recognition with high versatility can be used separately. In addition, special-shaped nozzles, universal imaging systems, etc. that support various special-shaped components are installed to further develop and improve the ability to support components.   2. Universal image system: This is a universal image system that can flexibly respond to evolving shaped elements. When data is compiled, part and overall confirmation of components can be confirmed in the preview screen, and the operation of identifying the edges and corners of the shape recognition component can further simplify data input and complete functions. High production performance: MNVC (Multi-Nozzle Vision Centering): This is a general-purpose imaging system that can flexibly respond to evolving irregular-shaped elements.

First let's know somthing about the categories of juki feeder.   ATF, CTF, FTF, but in fact we often call it AF / CF / FF Secondly, in addition to the latest ETF, juki feeder can be used on any juki model pick and place machine.   The following are the introduction of each juki feeder:   ① Juki ATF feeder is a new feeder developed by Juki based on KE2070 and above high-speed machine. The feeder is easy to use and can be changed without stopping the machine. The waste plastic bags and paper tape can automatically sag into the waste box without the reel.   However, there were frequent cassettes in the early stage of the launch of the ATF juki feeder, and the waste plastic bags could not be exported normally. Juki has improved this problem later, and now the ATF feeder on the market has completely solved the problem of the cassette.   ATF feeder has AF03HP, AF05HP, AF081E, AF081P and other models. At present, the ATF feeder has been developed to AF24MM. ② Juki feeder CTF model feeder is an old model feeder developed by Juki based on KE2050 2060 FX-1 medium speed machine. The feeder is easy to use. The waste plastic bags are taken up by the take-up reel, and the paper tape automatically sags into the waste bin. The CTF feeder , which has the highest market share, with a good reputation and stable quality.     CTF feeder has CF03HP feeder which use for 0201 components; CF05HP feeder pick 8*2mm feeder 0402 component; CF081E, CF081P feeder pick 0603 component. Now Juki has launched CTFR, a CTF upgrade. ③ FTF feeder is the general name of all mechanical feeders from 12mm (including 12mm) of Juki company. At present, almost all feeder in the domestic market are FTF models. This type juki feeder has also won a very good reputation among customers because of its stable quality.
