Robots in Danish electronics production
“Design-for-Manufacturability” – DfM – is a concept that should be taken very seriously in the design of electronics products in the future. This is the basis for robots to take over a number of the lonely tasks in the assembly of products to be manufactured in Denmark, and this will be the conference program for E-18 in Odense from 11 to 13 September.
The electronics industry has been one of the earliest users of robots in Denmark, and for more than twenty years, this part of the business has assembled components with the so-called pick’n place machines, making it possible for Denmark in the field of electronics to stand well in the competition from low-wage regions. There is even a tendency as many new industries use electronics as a central part of the function of their products – even though the products have not been thought of as “electronics” as a rule.
This is because, for example, the Odense Congress Center has expanded the E-18 electronics trade show with the new R-18 robot fair in an adjacent hall, and the conference programs for the two fairs also support each other. Robots are a prerequisite for continuing to retain the production of many types of products on Danish soil.
The link between development and production is more important than you really expect, and it is important that the experience of production is given back to the design and development of the products. Conversely, the prerequisite for automatic production is that the products are designed so that the robots can perform the installation, and here DfM, Design for Manufacturability, comes highly into the image.
Robot as a colleague
– Within the electronics assembly of components is no problem. The challenges today are to create products that can be assembled by robots or through collaboration between robots and human colleagues. Physical design is thus the primary task of the device designers, and the necessary tests of component components along the way must also be considered in the design, explains Poul Juul, head of Hytek in Aalborg and one of the country’s leading quality assurance experts, as well as optimizing electronic designs and products.
He points to the value of feedback from the many subcontractors who are currently involved in the production of a multitude of products. The knowledge of quality and efficient assembly at the production stage is vital if designers are to manufacture products that can be assembled and assembled using robots more than ever.
– A parameter that is not always considered is the version of the components to be used for the construction of an electronic or electromechanical construction. Many of the standard components included in today’s products have only a limited life in the supplier’s portfolio and therefore, as an OEM device (original equipment manufacturer), they no longer have the parts to be used in the construction, says Poul Juul.
He therefore recommends that you greatly consider modularity in his product design. This will make it easier to change a given design if components or standard parts change shape or become inaccessible during the end-product life of the market. It will also reduce the changes in programming that the robots will require in connection with changes in the design.
A major problem is, according to Poul Juul, that different technical groups do not always understand each other’s language. In fact, rarely rarely when it’s up to date. DfM first makes sense when everyone understands each other’s mutual issues and languages. Control and communication becomes crucial when hardware, software, power supply, user interface, cabinet and assembly need to be done more or less in parallel.
– Finally, there is the whole test aspect that should also be taken into account in its design. The more complex systems you have to do, the more important it is that the system is largely able to test itself. In fact, many of the CPU processors – used in today’s electronics are designed to perform self-test. And then it makes sense to build a bus and a port for testing in its electronic design, “ends Poul Juul.
