China Spi Machine on Line for LED Light Line Solder Paste Inspection for SMT Printer

SPI Solder Paste Inspection Machine

Introduction
RX-3DSPI-80 SPI is an online multi-function 3D solder paste inspection equipment (3D-SPI) independently developed by Ruixin Automation. Screen printing and component placement are the two most likely factors that cause defects. The defect rate caused by problems related to the printing process accounted for 51%, and the defect rate caused by inferior patches accounted for 38%. These failures are not only the material and labor costs, but also the indirect manufacturing costs, warranty fees, customer satisfaction and opportunity costs. SPI can reduce the problems caused by solder paste printing. Equipped with dual-direction grating light source technology, it can completely solve the shadow problem and the chaotic reflection problem in the detection process, so that the three-dimensional detection accuracy of the solder paste is higher; At the same time, it is equipped with a high-speed camera with ultra-high-definition pixels. The detection speed is faster and the image is more delicate and rich; Support engineering programming and optimized interface structure to enhance the ease of operation, and improve the detection and processing functions of the test results. The operator can quickly process the data and use the bad information interface of the actual picture to let the operator not need to compare with the actual board. It is easy to confirm the defect. The RX-3DSPI-80 is the preferred product for efficient, high precision, high quality production lines.
AdvantagesUsing Windows 7 operating system, 3D-SPI dedicated software independently developed by Ruixin Company.The professional lens design of the light source makes the image more uniform and delicate, greatly improving the stability of the detection.The exclusive design of the dual-direction light-emitting system technology makes the measurement accuracy higher and the measurement range larger, completely solving the shadow problem and the chaotic reflection problem in the detection process.Programming and debugging is easier, and Gerber is imported as standard data, which can be put into test within 10 minutes.With 3D compensation function, the Z-Tracking function of multi-cycle measurement technology is used to measure the real-time compensation of the bending difference caused by the reference plane.The test parameters are greatly reduced, and the white line interference problem can be easily solved.The operating system improves the detection result confirmation and processing functions according to the user-level optimized interface structure.The 3D-SPI and AOI test data can be saved to a central database, and the results of the printing and the results of the patch can be displayed and judged at the same time.based on accurate 3D measurement data, the operator can optimize the entire project in a short period of time.A powerful SPC management system at a glance;Quick and intuitive programming;Two-way projection system to effectively eliminate shadows;True color three dimensional image ;MES data generation, online real-time monitoring of production;Offline programming function, synchronous programming during real-time online testing;The motion platform adopts servo motor and high-precision ball screw structure, which is high-speed, stable, vibration-free and noise-free. It is combined with high-precision grating to form a full-closed feedback system with repeatable motion accuracy of 1μm.User-friendly human-machine interface, support Gerber files in RS274-D, RS274-X format and CAD files supporting dxf format. After importing files, pad information is automatically created. Simply set the detection parameters to complete programming.Comprehensive and detailed SPC analysis system, the operator can intuitively view the comprehensive statistics of test information through pie chart or column chart, etc. The statistical information can be output in Html, Excel or Image format;Diverse functional modules, such as red glue detection, bare board learning programming, automatic plate bending compensation, camera bar code recognition, offline programming and debugging, and detection frames can be adjusted at any time.

SPI phase measurement technology
The grating phase light source used, the distortion generated by different height planes, the detection head continuously moves in a certain direction, the camera takes photos at set time intervals, thereby obtaining a set of laser distortion data, and then calculating to obtain the test result.

Software control of the grating motion is realized, which avoids the mechanical devices necessary for the traditional piezoelectric ceramic motor (PZT) to drive the glass moiré grating, reducing mechanical wear and customer maintenance costs.
16-bit grayscale resolution, up to 0.3 micron detection resolution, 2 orders of magnitude better than laser measurement accuracy, greatly improving the detection capability and scope of the device.
