Automatic robot programming for a wide variety within product families

Automatic Robot Programming (ARP) often seems out of reach for companies with a wide variety of products within the same product families. It is often thought that each variant of the product requires its own welding programme to be programmed.

The Quick Program Configurator (QPC) software, developed by Valk Welding, changes this. QPC applies automatic robot programming specifically in situations where there is a wide variety of products within the same product families.

How does QPC work?

By using parametric data, QPC can quickly and accurately generate programmes for different product variants, regardless of complexity or specifications. This means that companies are no longer stuck with standard programmes for every variation of the parent product, but can instead dynamically generate customised welding programmes, sometimes within 30 seconds. Whether it involves adjusting the length, width, or other parameters, QPC ensures that each product within the family is manufactured with the same precision and quality.

Parametric data

Necessary for automatically generating robot programmes with QPC are the parametric data and the setup of the database. In this database, a parent programme is created based on the already known parametric data. This includes welding parameters as well as information about fixed spacings of elements, types of welds, the number of angles, and/or torch positions.

The QPC software can then automatically generate robot programmes by scaling, expanding, and extending the parent programme until it meets the requirements of the specific workpiece to be welded. In the case that a product contains various elements with a fixed spacing, the QPC software will calculate the number of elements based on the entered total length and will add the correct welds for all elements to the total programme.

QPC interface

QPC can be integrated into the production process specifically for the customer. The software can be implemented with an interface where the operator enters the correct dimensions of the product to be welded on a screen next to the robot installation, after which QPC directly calculates the welding programme. However, QPC can also play an important role in further automation of the production process.
Think of (automatically) scanning a QR code that contains the necessary information for QPC. After scanning this QR code, the QPC software will immediately start generating a welding programme for that specific product based on the entered source data.

Tilbox

One of our customers, the company Tilbox from Valkenswaard, uses QPC daily for the production of upper and lower boxes for trucks and trailers, where programmes can be generated within 30 seconds. Curious about their experience? Read the story on page 16.

• Shortest possible cycle time
• Maximally optimised programmes
• No programming time
• Based on textual data of a product
• Can use parametric data from CAD software
• Various input options:
• Manual
