Oriented by customer needs, CCD visual alignment is upgraded again

In the thick film printing process of electronic components, the CCD visual alignment system can automatically correct deviations, effectively control errors caused by manual feeding, and improve the yield rate in mass production. It is widely used in high-precision thick film printing.However, due to the complexity of operation and debugging, the requirements for skilled workers are relatively high during production and use.Recently, many old customers have asked whether the operation difficulty can be simplified and the printing accuracy can be improved when they repurchase.

In response to these problems, in 2023, we visited a number of customer companies to understand the actual production needs, organized the company's technical team to conduct multiple discussions on the alignment system, and arranged for technical personnel to conduct multiple technical communications with customers.In the end, we ignored the cost investment and cooperated with CCD vision system manufacturers to conduct a large-scale upgrade of the existing software and introduced a new CCD vision alignment system.
Introduction to the traditional alignment method: manually align the product with the stencil position, and then align the visual lens to the product to grab the MARK point for alignment. The alignment rate of the product and the stencil graphic depends entirely on the state of the first manual alignment.Then perform platform compensation after discovering the deviation (compensation data is entered manually and automatically compensated during alignment).When the product and stencil graphics meet the production standards, the adjustment is completed.

Introduction to the new version of alignment method: take out the graphics of the stencil (MARK points) by printing, the CCD will set it as a reference by learning the printed MARK points, then place the product to be printed and register the MARK points (template) of the product.During alignment, the template will automatically move toward the reference to completely coincide with the product and stencil graphics.
