Definitions
- the present invention relates to a coating device for
- the invention also relates to a coating system.
- the coating of components, such as spark plug housings, by means of drum coating is known.
- the components are introduced into a drum as bulk goods, with the components in the drum then going through all coating steps as bulk goods.
- the coating device according to the invention with the features of claim 1 offers the advantage of an improved device by means of which high-quality coatings of components can be produced in a short time.
- a coating device which comprises a housing with an outer anode, an inner anode and a voltage generating device.
- the outer anode is thus part of the housing and is designed to receive the component, which is preferably a spark plug housing, that is to say to grip around the component.
- the inner anode can be inserted into a through opening of the component.
- the voltage generating device is set up to generate a first voltage between the outer anode and the component and a second voltage between the inner anode and the component.
- the housing also has an inlet and an outlet. A process medium can be introduced into the housing through the inlet and the process medium can be discharged from the housing again via the outlet.
- the coating device is thus designed in such a way that it can each receive exactly one component, with both an outside and an inside of the component being able to be coated, advantageously nickel-plated, completely and with high quality. Due to the direct flow around the component by means of the process medium, a very high
- Coating speed i.e. a very rapid deposition of a layer on the component, can be achieved.
- the housing preferably further comprises a cover with a clamping device.
- the clamping device is designed to clamp the component in order to hold the component in a predefined position within the outer anode. That is, the component is held in a defined manner in the housing by the clamping device alone.
- the component is particularly preferably a spark plug housing with a
- the clamping device is set up to clamp the ground electrode. This results in a particularly simple possibility of holding the spark plug housing inside the outer anode.
- the clamping device is designed so that this one
- the clamping device covers at least 80%, particularly preferably at least 95% of the surface of the ground electrode in this clamped state. That is, the clamping device engages around the
- Ground electrode of the spark plug housing in such a way that, on the one hand, this enables the spark plug housing to be held in a defined manner within the outer anode and, on the other hand, that a surface of the ground electrode is largely covered. This prevents the ground electrode from coming into contact with the process medium during the coating process and thus being excluded from the coating. This is particularly advantageous if only a partial coating of the spark plug housing is intended. It is also advantageous if the process medium is a nickel electrolyte. The coating thus corresponds to nickel-plating the component, i.e. a nickel coating is produced on the component.
- the inner anode is preferably adjustable along a longitudinal axis of the housing in order to adapt the generation of the coating on the inside of the component. For example, a different layer thickness of the coating on the inside of the component can thereby be achieved.
- the coating device further comprises one
- the flow control device is a perforated diaphragm, which is preferably rotatable.
- a rotatable perforated diaphragm can be provided as two disks which can be rotated relative to one another and have several through holes. By turning the two disks against each other, an overlap of the through holes changes, whereby a total free flow cross section, and thus a flow through the housing, can be set.
- a first flow between the inner anode and / or a second flow between the outer anode and the component can be regulated by means of the flow control device. It is particularly favorable if the first flow and the second flow by means of the
- Flow regulating device can be regulated independently of one another in order to be able to adapt the flow of the process medium through the housing particularly flexibly to the desired properties of the coating inside and outside of the component.
- the invention leads to a coating system which has at least one, but preferably at least 20, and particularly preferably 48,
- Coating devices includes. Furthermore, the
- Coating system at least one, preferably exactly two voltage generating devices per coating device
- FIG. 1 the invention is illustrated in FIG.
- Figure 1 is a simplified schematic sectional view of a
- FIG. 1 shows a simplified schematic sectional view of a
- Coating device 1 according to a preferred embodiment of the invention. An operating state of the coating device 1 is shown while a component 2 arranged in the coating device 1 is being coated.
- the component 2 is a spark plug housing with a straight ground electrode 22.
- the coating device 1 comprises a housing 3 with an outer anode 4.
- the housing 3 extends essentially along a longitudinal axis 10.
- the component 2 is arranged inside the outer anode 4.
- the outer anode 4 has an inner contour which is adapted to an outer contour of the component 2.
- An inner anode 5 of the coating device 1 is arranged within a through opening 21 of the component 2.
- the inner anode 5 is fastened to a base 35 of the housing 3 by means of a screw 51.
- the inner anode 5 can be adjusted along the longitudinal axis 10 by means of the screw 51.
- the housing 3 comprises a cover 8 with a clamping device 81.
- the grounding electrode 22 of the component 2 is in the clamping device 81
- the ground electrode 22 is shown in FIG. 1 in a not yet bent state, and thus also extends in the direction of the longitudinal axis 10. As can also be seen in FIG. 1 by clamping the ground electrode 22 in the clamping device 81, more than 90% of the surface of the ground electrode 22 is covered by the clamping device 81 in order to prevent the ground electrode 22 from being coated on precisely this covered surface.
- the housing 3 has an inlet 31 on the bottom 35, via which a process medium can be introduced into the housing 3 in the direction 71.
- an outlet 32 is provided in the housing 3, via which the process medium, after it has flowed over or flowed through the component 2, can be discharged again in the direction 72 from the housing 3.
- the coating device 1 further comprises a
- the flow control device 9 which is arranged at the transition between the bottom 35 and the outer anode 4.
- the flow control device 9 is designed as a perforated diaphragm with a plurality of holes 91 in order to regulate a flow, in particular a volume flow, of the process medium through the housing 3 by rotation.
- the process medium is a nickel electrolyte, by means of which a nickel coating can consequently be produced on the component 2.
- the coating device 1 further comprises a voltage generating device 6.
- a first voltage can be generated between the external anode 4 and the component 2 by means of the voltage generating device 6.
- a second voltage can also be generated between the inner anode 5 and the component 2.
- the nickel coating can be generated both on the inside and on the outside of the component 2.
