The perfect application process for double-sided adhesive die-cut parts: the application system

In recent months, our blog series focused on bonding has shown that manufacturing industries frequently use double-sided adhesive die-cut parts (DSAP) to join two components together. This post illustrates how DSAP application works.  

The Competence Center Schreiner Services has developed a special machine for a customer that makes reliable processing combined with camera inspection possible. Specifically, the project involved a magnet to be joined with a sensitive electronic component with maximum precision. “The objective of this innovative machine development was a coordinated overall solution that would allow us to offer the customer processing and process control from a single source as well,” explains Michael Reineke, Head of the Competence Center Schreiner Services. Because the development of such a complex manufacturing cell takes half a year, he and his team started out by building a handheld application tool enabling the customer to initially process several hundred products without long waiting periods. During the project, the mechanical engineering experts from Schreiner Services together with the customer’s team came up with improvements to further enhance the process reliability of the system. As a result, the customer not only benefits from the high quality of the double-sided adhesive die-cut parts but is simultaneously provided with a processing solution that includes camera-based inspection tailored to meet the customer’s specific needs.

The process consists of several individual steps, starting with the extraction of the magnet from a blister and centering it in order to achieve high accuracy of fit when joining the magnet with the electronic component. Subsequently, the machine positions the magnet on the DSAP and separates the latter from the liner. Now the composite is applied to the manually inserted component, immediately followed by camera inspection. The camera checks positioning accuracy and transmits this information to the product database. Should the camera detect a fault the machine will stop the production run until the defective part has been removed and disposed of. Consequently, only OK parts move on to the next processing step. Michael Reineke sums up the benefits of the project: “We have developed a complex machine with many customized features ensuring optimal processing of the double-sided adhesive die-cut parts. This provides the customer with certainty that faults are precluded in the application stage of the production process and that no defective products leave the assembly line.”

Schreiner ProTech is addressing all aspects relevant to adhesive bonding as a joining solution in a series of blog posts. The following questions have been covered to date: What capabilities does an adhesive have to deliver and how does adhesive bonding work? When should adhesive bonding be used and what are the differences between liquid and pressure-sensitive adhesive bonding? What are the key criteria in the selection of an adhesive? What additional functions are possible when using self-adhesive die-cut parts? In addition, we have shown specific examples from various industries.
