This high-frequency signal supplies the electrical treatment unit 3 via the at least one second supply line 62, the coupling 63, 64 and the at least one first supply line 61 when the first and the second coupling element 63, 64 are coupled together.
- the coupling In the coupled state, that is, when the first coupling element 63 is coupled to the second coupling element 64 of the coupling, the coupling provides an electrically conductive connection between the first supply line 61 and the second supply line 62.

- the actuating element 71 comprises an electromagnet and the second coupling element 64 comprises, on a side facing away from the first coupling element 63, a magnetic counterpart 69 on which the actuating element 71 can engage with the electromagnet.
- the magnetic counterpart 69 comprises a magnetic material, such as a magnetic metal.
- control of the electric magnet in the actuating element 71 takes place via a control line 72, which is shown schematically in FIGS. 3A-3C.
- the solenoid Via this control line 72, the solenoid is either activated or deactivated. In activated State, the solenoid can be frictionally associated with the magnetic counterpart 69 on the second coupling element 64 in connection.
- the actuating unit 7 comprises a linear drive 73, where the actuator 71 is attached.
- the linear drive 73 is configured to move the actuating element 71 linearly in order to be able to bring the actuating element 71 into contact with the second coupling element 64 and thus to actuate the second coupling element 64, that is to say to withdraw it from the first coupling element 63 or bring the second coupling element 63 in contact.
- the linear drive 73 includes, for example, a pneumatic cylinder or a linear electric motor. The supply or control of the linear drive 73 via a further supply line 74th
- the at least one second supply line 62 within the housing 66 forms a cable loop which, when the first and second coupling elements 63, 64 are coupled together, allows rotation of the shaft 2 without the second supply line 62 tearing off or otherwise damaged.
- the second supply line 62 may be guided within the housing 66 in a cable train 65.
- the extent to which the shaft 2 can rotate with coupled clutch 63, 64, without the clutch 63, 64 solves itself or the second supply line 62 breaks off, is dependent on the length of the second supply line 62 within the housing 66, that is dependent on the line reserve of the second supply line 62.
- the second supply line 62 is dimensioned so that the shaft 2 coupled coupled clutch 63, 64 a rotation range of a maximum of 180 °, a maximum of 270 °, a maximum of 360 °, or even a maximum of 720 ° has.
- the "rotation range” denotes an NEN angular range between a first end point and a second end point of the shaft.
- first endpoint refers to an angular position to which shaft 2 can be rotated in coupled coupling 63, 64 in a first direction without the risk of damaging the power supply assembly
- second endpoint refers to an angular position the shaft 2, to which the shaft 2 can be rotated in a direction opposite to the first rotational direction of the second rotational direction, without the risk of damage to the power supply arrangement.
- Figures 3A and 3B show the shaft 2 in an angular position at which the operating unit 7 can couple the two coupling elements 63, 64 together or decouple from each other.
- the shaft 2 can be rotated in a first direction, which in the example corresponds to the clockwise direction, a piece, without the risk of tearing off the second supply line 62.
- the cable loop of the second supply line 62 below the shaft 2 then shortens and the second supply line wraps around the shaft 2.
- An optional clamping element 68 which is displaceable in the vertical direction in the example, holds the second supply line 62 in this case stretched or keeps the loop upright.
- the shaft 2 can be rotated clockwise by up to 360 °.
- the shaft 2 can also be rotated in the example by 360 °, without the risk of tearing down the supply line 62.
- the shaft can thus rotate in both directions by 360 °, i. be rotated by +/- 360 °.
- the rotation range is thus 720 °, since the two end points are 720 ° apart.
- the further supply line 62 is inserted in the illustrated example on a side wall in the housing 66.
- the actuating unit 7 is located on a side wall of the side wall opposite the first side wall. This is just one example.
- the introduction of the second supply line 62 into the housing 6 can take place at any point. Decisive for the permissible rotational range of the shaft 2 with coupled coupling is the existing within the housing 66 cable reserve of the second supply line 62, so the length of the second supply line 62 within the housing 66. The longer this supply line 62, the greater is the range of rotation.
- the coupling with the two coupling elements 63, 64 may be a conventional Liehe electrical coupling, which ensures an electrically conductive connection between the two supply lines 61, 62.
- one of the two coupling elements 63, 64 may, for example, comprise contact pins which, in the coupled state, plug into corresponding sockets of the other coupling element.
- both coupling elements 63, 64 have contacts which are designed as spring contacts.
- a mechanical connection between the two coupling elements 63, 64, which prevents an automatic release of the coupling can be ensured in different ways, such as by clamping elements, spring elements, or the like.
- one of the two coupling elements 63, 64 has a permanent magnet on a contact surface facing the respective other coupling element, which in the coupled state of the coupling elements 63, 64 is non-positively connected to a magnetic counterpart of the respective other coupling element to hold the two coupling elements 63, 64 together in the coupled state.
- FIGS 4A and 4B respectively show plan views of a contact surface of the first coupling element 63 ( Figure 4A) and the second coupling element 64 ( Figure 4B) according to one example.
- each of the coupling elements 63, 64 comprises four contacts 631-634 and 641, respectively - 644.
- Each contact element of a coupling element has a corresponding contact element on the respective other coupling element and is in electrical contact therewith when the two coupling elements 63, 64 are coupled.
- the individual contact elements 631-634 or 641-644 may be formed as conventional electrical contacts, such as spring contacts. It is also possible to realize one of the corresponding contacts as a contact pin and the other of the corresponding contacts as a contact socket.
- the number of contact elements is arbitrary and dependent on the respective purpose or the number of electrical consumers to be supplied, and thus not limited to four.
- At least one of the two coupling elements 63, 64 has at the contact surface a permanent magnet, which engages in the coupled state on a magnetic counterpart of the respective other coupling element 63, 64.
- the permanent magnet and the magnetic counterpart are denoted by the reference numerals 635, 645 in FIGS. 4A and 4B. These are arranged in the illustrated embodiment in an annular manner around the contacts 631 -634 or 641-644. This is just one example. Any other geometry is also possible.
- a permanent magnet is present.
- This permanent magnet corresponds either to the element designated by the reference numeral 635 in FIG. 4A or to the element denoted by the reference numeral 645 in FIG. 4B.
- the counterpart then consists of a magnetic material, such as a magnetic metal.
- a permanent magnet to be provided on each of the two coupling elements 63, 64, wherein these magnets are arranged on the contact surfaces in such a way that the permanent magnets are in contact with each other at the contact surfaces, ie at the surfaces which are in contact with each other in coupled coupling, have opposite magnetic poles, so that the permanent magnets attract each other.
- the electromagnet of the actuating element 7 and the magnetic counterpart 69 on the second coupling element 64 are dimensioned such that the actuating element 7 is capable of the second coupling element 64 against the magnetic force caused by the at least one permanent magnet and the magnetic counterpart of the coupling elements 63, 64 to solve each other.
- the rotational range of the shaft 2 is coupled coupled clutch 63, 64 in the manner previously explained.
- the shaft 2 can not be completely rotated several times in succession in one direction.
- any pivoting that is, an alternating rotation of the shaft in one direction of rotation and the opposite direction of rotation is arbitrary lent borrowed.
- the treatment unit 3 can be positioned at an arbitrary angular position within the treatment chamber 1 or freely swiveled back and forth within the rotation range.
- decoupled coupling 63, 64 there is no restriction on a rotational movement of the shaft 2. That is, the shaft can be completely rotated in this case several times consecutively in one direction.
- a first nozzle tube 51 (see FIG. 1A) is fastened to the shaft 2 in addition to the electrical treatment unit 3.
- This nozzle tube 51 comprises a plurality of nozzles 52 arranged along the nozzle tube, via which cleaning liquid can be dispensed in the treatment chamber 1 in the direction of the component holder 12, and thus in the direction of the workpieces to be cleaned.
- the supply of cleaning liquid to the nozzle tube 51 takes place from outside the treatment chamber 1 via a liquid channel 23.
- This liquid channel 23 runs in the illustrated embodiment centrally within the shaft 2.
- Within the treatment chamber 1 opens a radially extending in the shaft 2 bore in this liquid passage 23.
- the nozzle tube 51 is fixed in the region of this radial bore on the shaft 2 that cleaning fluid can pass through the liquid channel 23 and the radial bore in the nozzle tube 51.
- the supply of cleaning liquid in the liquid channel 23 of the shaft 2 for example via a feed pipe (not shown in the figures), which is arranged outside the treatment chamber and against which the shaft 2 is rotatably mounted.
- Conventional seals can be used to ensure that no liquid escapes in the region in which the feed tube is coupled to the shaft 2.
- the treatment device may comprise a further nozzle tube 53 fixed to the shaft 2.
- This further nozzle tube 53 serves, for example, for introducing a gaseous medium, such as air, into the treatment chamber 1.
- the gaseous medium can be used, for example, for drying the workpieces previously cleaned with cleaning fluid.
- the shaft 2 comprises a further feed channel extending within the shaft in its longitudinal direction from outside the treatment chamber into the treatment chamber.
- This further feed channel opens into the further nozzle tube 53 within the treatment chamber 1 and is accessible outside the treatment chamber via a bore 24 extending perpendicularly to the longitudinal direction. This bore 24 is shown for example in Figures 3A and 3B.
- annular channel (not shown) may be provided which surrounds the shaft 2 in the circumferential direction in the area of the bore 24. This annular channel opens in each angular position of the shaft 2 in the bore 24.
- an annular channel for supplying a gaseous medium in a shaft of a treatment device is known, so that it can be dispensed with further embodiments in this regard.
- decoupled coupling 63, 64 the treatment device can be operated like a conventional treatment device.
- cleaning liquid can be discharged via the first nozzle tube 52 to workpieces in the treatment chamber 1, wherein the first nozzle tube 52 in the shaft 2 in the treatment chamber 1 can be arbitrarily rotated or pivoted.
- a gaseous medium can be delivered to the workpieces via the second nozzle tube 53 in the treatment chamber. This can be done to dry the parts.
- the liquid bath can take place by introducing cleaning liquid via the first nozzle tube 52.
- the treatment chamber 1 has an additional liquid inlet (not shown).
- the treatment chamber 1 also has a liquid outlet at a lower end in order to be able to discharge cleaning liquid previously introduced into the treatment chamber 1.
- FIG. 5 shows a block diagram for explaining the mode of operation of the treatment device or for explaining the interaction of the individual elements explained above. Referring to FIG.
- the treatment device has a controller 100.
- This controller may include, for example, a programmable controller such as a microprocessor.
- the controller 100 controls the motor 41, which rotates the shaft 2 in accordance with the controller 100.
- the controller 100 receives information about the current angular position of the shaft 2 from a rotary encoder 101, which is arranged in a manner not shown in the region of the shaft 2 and which transmits to the controller 100 the current angular position of the shaft 2.
- the controller 100 also controls the actuating unit 7 for the coupling 63, 64 and optionally the supply of the cleaning liquid or the gaseous medium via the shaft 3 to the two nozzle devices 52, 53.
- the controller 100 moves the shaft 2 via the motor 41 into a coupling position. This is the position shown in Figs. 3A and 3B. In this position, the actuating element 71 of the actuating arrangement 7 can act on the second coupling element 64. If the coupling 63, 64 is coupled and is to be decoupled, then the controller 100 ensures that the electric magnet of the actuating element 71 is energized and causes the linear drive 73 to move linearly in the direction of the second coupling element 64 to an end position at which a frictional connection between the actuator 71 and the magnetic counterpart 69 is ensured.
- the controller 100 then effects a process of the linear drive 73 in the opposite direction to decouple the second coupling element 64 from the first coupling element 63.
- the second coupling element 64 is permanently held by the actuating element 71, so the electromagnet remains energized until the two coupling elements 63, 64 are coupled together again.
- the control also causes the shaft 2 to be moved to the clutch position by the motor 41.
- the controller 100 then causes the linear drive moves in the direction of the first coupling element 63, to an end position at which the first coupling element and the second coupling element are coupled together.
- the energization of the electromagnet of the actuating element 71 is then interrupted in order to be able to drive the actuating element 71 away from the second coupling element 64. This is likewise effected under the control of the control 100.
- the actuating element 71 is thereby moved to a waiting position (shown in FIG. 3A), on which the actuating element 71 remains until the two coupling elements 63, 64 are to be decoupled again.
