Description

Device for filling non-vacuum-resistant systems by means of vacuum pressure filling Technical Field The invention relates to a device for filling components of a non-vacuum-resistant system with a working material by means of vacuum pressure filling and for subsequently closing the same. Background For many technical applications, liquids or gases must be fed as operating materials to the plant technical system. In order to be able to achieve airless filling of the individual systems, pressure filling with the aid of vacuum is increasingly being carried out. The system to be filled is first evacuated by means of a vacuum pump to suck the gas contained in the system. Thus, the airless of the system is achieved before filling with the respective filling medium. A typical field of application for vacuum pressure filling is the automotive industry. In this case, the vehicle is filled with the necessary operating materials on the manufacturer's assembly line. These operating materials are fed from the filling device via the connecting lines and the filling adapter into the circuit and the container of the motor vehicle to be filled. Such applications are described, for example, by DE 197 00 436C2, DE 10 2007 029 020 A1 and DE 10 2014 011 611B4 is known and does not cause problems due to the principle, since the circuit and the container of the motor vehicle to be filled are designed to be vacuum-resistant. And if vacuum pressure filling is to be used to fill a system that is not vacuum tolerant, the system will collapse under vacuum loading. A typical example hereof is an ultrasound probe for applications in medical technology. These components are filled mainly by means of an through-scavenging, which does not however lead to an airless filling. To date, there is no alternative method available on the market for airless filling of such components. Disclosure of Invention The object of the invention is to provide a device with which a system that is not resistant to vacuum can also be filled and closed without air by means of vacuum pressure filling. This object is achieved in that the device has a vacuum chamber for accommodating at least one component to be filled. A rotation device is arranged in the inner cavity of the vacuum chamber in the lower region to support and move at least one receiving unit for the component to be filled. The at least one receiving unit is assembled from at least two individual segments, which in the assembled position form a common free space in their interior, the inner contour of which corresponds to the outer contour of the component to be filled. Another free installation space is formed in the section of the receiving unit above the outer contour of the component to be filled. In the inner cavity of the vacuum chamber, a screw tool for the closing element of the component to be filled and a filling unit are arranged above the receiving unit. The screw tool and the section of the filling unit to be operatively connected to the component to be filled can each be moved into a further free installation space of the receiving unit above the outer contour of the component to be filled. Further advantageous embodiments are the subject matter of the dependent claims, the technical features of which are described in detail in one embodiment. The basic solution is therefore to arrange a non-vacuum-resistant component or a complete vacuum-intolerant system in a vacuum chamber with structurally integrated filling and closing technology and to move it into the position optimal for the respective method step using special operating technology. In this case, the vacuum chamber has only a single opening, so that in principle a different method sequence is possible than in the case of the filling of systems which were not resistant to vacuum by means of throughsweep gas which has been customary hitherto. The non-vacuum-resistant components can also be evacuated by using a vacuum chamber in which the component to be filled or the system to be filled is located during evacuation and filling. This is achieved by also evacuating the vacuum chamber during evacuation. Thus, the pressure in the component to be filled or in the system to be filled remains the same as the pressure surrounding it. Thus, collapsing of the component to be filled or the system to be filled can be avoided and subsequently the running material can be filled without air. In applying the solution according to the invention, no manual operation of the component to be filled or of the system to be filled is required in order to adapt the filling tool. All necessary translational and rotational feed movements can be achieved by means of components which are structurally integrated in the vacuum chamber. In this case, it is functionally important that all seals between the drive arranged outside the vacuum chamber and the filling and handling technology arranged inside the vacuum chamber are embodied in a vacuum-tight manner.
