Passive hexapod positioner with innovative preloaded joints for accurate reconfigurable positioning of fixtures or jigs
A Slovenian company with a 40-year tradition in automatic systems for product assembly is offering a patent pending hexapod technology as a reconfigurable alternative to dedicated jigs and fixtures in automated production lines. The company is looking for automation integrators for technical cooperation under commercial agreement with technical assistance and an investment partner for collaboration under an investment agreement.
Type of partner sought: The company is seeking automation integrator to adopt the technology via commercial agreement with technical assistance. Additionally, the Slovenian company would like to find a possible investment partner for a collaboration in the form of a partial transfer of shares of its company in Denmark. Activity of Partner: The partner sought develops and sells automation production lines for manufacturing industries. In case of establishment an investment agreement the investment partner should have the experience and established relationships in the market of industrial automation. Specific role of partner sought: Implement the innovative hexapod technology with the support of the Slovenian company to enable flexible automation system with better reconfigurability and more accurate positioning of the jigs and fictures in the reconfigurable robotic cells.
A Slovenian company with a 40-year tradition in automatic systems for product assembly is offering an innovative 6-axis hexapod positioner technology as a reconfigurable alternative to dedicated jigs and fixtures in production. The technology has been developed in collaboration with the leading Slovenian public research technological institute which is further providing its suport to the company with its automation and robotics research and development competences and infrastructure. For the commercialization purposes the Slovenian SME cofounded the Institute’s spin-out company in Denmark. A 6-axis motion hexapod platform is a well known Stewart hexapod concept for use in various industrial applications. For example, where motion in 6 degrees of freedom is needed for a freely-suspended body to move, e.g. in robotic assembly, welding and manufacturing. Such competitive hexapod platforms lack suficient accuracy and rigidity of the flexible joints which enable the platform to move in 6 degrees of freedom and to accurately position the robotic arm to the desired position in the automated production process. The proposed hexapod technology of the Slovenian company comprises an innovative solution of flexible joints which enable very accurate positioniong by an external positioning device (e.g. robot) of the tool in the fixture or jig in the production process and fewer changes to dedicated fixtures e.g. in the precision welding, automated assembly and other manufacturing application. This is especially important in automation applications such as automotive white body assembly, automotive light assembly, personalised assembly of mechanical elements, etc, which have to be done automatically, fast, accurate and in an affordable way. The Slovenian SME is seeking manufacturing systems developers and automation integrators who seek to offer clients an innovative method of improving the flexibility of their production lines. The partner sought develops and sells automation production lines for manufacturing industries which have ambition to reduce the costs of frequent reconfiguration of their production lines and would like to enable the use of the proposed hexapod technology in their commercial offer of the automated production lines for their customers. The preferential industries are automotive and aerospace industry, and also other industries where assembly processes need personalised features and are a big part of production, like semiconductory, plastic, rubber, metal and railways industries. The Slovenian SME is offering the cooperation under commercial agreement with technical assistance. Services included in the offered cooperation are: - assistance with the transfer of all technical know-how needed for integration of the technology in the specific application of the partner sought; - assistance with the customization of the hexapods for specific applications – (e.g. diferent payloads of the platform) can be developed and produced; - supply of the hexapods; - the Slovenian SME will provide the support in the definition of the value of the proposed solution (Return of investment, yearly savings and reduce of work) for the end customers. - the Slovenian SME will suport the partner in the integration and maintenance activities. Additionally, the Slovenian SME would like to establish a relationship with an investment partner. The investor should have an experience with projects in the area of industrial automation.
Advantages and innovations
Autonomous hydraulic system: the hexapod system requires no motors, no cables and no wires. A pressure intensifier, controlled by a single external pneumatic valve effectively releases and activates the hydraulic clamping system around the segment securing an accurate position. Fixture configuration: several hexapods can be aligned – the number will depend on the fixture configuration. Beside automatic (robotic) reconfiguration, it can also be reconfigured manually. Easy reconfigurability: the hexapod system ensures flexible transition between batch productions, especially in production lines like automotive industry, while also assuring the ability to keep clamping position in case of power failure or disconnecting the fixture from external power when moving on the production line. The reconfiguration takes between 5-30 seconds, depending on degree of difficulty of the reconfiguration. Short return on investment (ROI): because the hexapods are passive and use an already-present robot to reconfigure itself, it is significantly more cost-effective than existing solutions, including motorized hexapods available on the market today, motorized fixtures or regular dedicated fixtures / jigs. Replacing even a small number of dedicated fixtures will thus provide a short return on investment for the user. As opposed to the well known concepts of the 6-axis motion hexapod platforms, the proposed technology comprises a patent pending solution of preloaded cardan joints at the crossing over to six mounting points on a bottom plate and on a top plate of hexapod platform. The innovative joints enable very high and adjustable stiffness and thus accurate positioning by an external positioning device (e.g. robot) of the tool in the fixture of jig in the precision welding, automated assembly and other manufacturing application.

EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
