Definitions
- Relays with relay housings are known from the prior art, the corrosion protection of which consists of a galvanically applied chemical coating.
- the previously galvanized housings are then, for example, yellow chromated or black chromated.
- Corrosion protection is also occasionally achieved using conventional organic coating materials, for example using water-based paints.
- the processes mentioned require a relatively long process time until the coating is applied and cured. The amount of waste generated by these processes is considerable.
- the inventive method for coating a relay with the features of the main claim has the advantage that the joint between two housing parts of a relay receives a reliable, quickly manufactured seal. Because of the short drying time it is possible to clear use smaller systems for coating. The corrosion protection and the quality of the surface of the relay improve considerably compared to the previous one.
- the lacquer seal can be applied in a targeted manner and without loss or waste. The same applies in principle to the lacquer seal sprayed specifically and fluidly onto the joint.
- the lacquer strip or the sprayed-on seal can be applied to the relay all around in a particularly economical manner.
- Lacquer seal coated with a colored lacquer layer the lacquer seal cannot be cured with ultraviolet radiation or only with difficulty.
- the housing is pretreated, for example with phosphating, to ensure favorable adhesion of the paint initially applied to the housing. Adhesion of the UV-curing coatings (UV sealing compound and UV varnish) is achieved with all metals and a variety of plastics (eg thermosets).
- the lacquer seal is applied through at least one nozzle, which is guided by touching it by means of a guide part on the housing, it is achieved that the lacquer seal is applied to the joint despite any manufacturing inaccuracies.
- the precise positioning of the guide part by touching the relay in the joint - which is a groove towards the outside - enables precise guidance of the guide part.
- the positioning can also be done without contact. This avoids the application of the lacquer seal at an unforeseen location.
- the method according to the invention is used particularly advantageously in a relay of a starting device for internal combustion engines.
- the coating of a relay using UV-curable varnish is not sensitive against fuels and lubricants as well as water and various cleaning agents that are usually used in engine washes.
- the paint seal is particularly insensitive to thermal expansion and thus reliably seals the relay housing.
- FIG. 1 a shows a relay according to the invention in a side view
- FIG. 1 b shows the relay in a side view from the right
- FIG. 1 c shows the relay in a side view from the left
- FIG. 2 shows a detail of the relay from FIG. 1 a
- FIG. 3 shows one Partial cross section through the relay at the joint between the coil housing and the relay cover
- Figure 4 shows a similar section of the relay in a second embodiment
- Figure 5 shows a partial cross section through the relay with two different representations to apply the paint seal
- Figures 6a to 6e show different sections of the method according to the invention.
- a relay 10 is shown for a starting device, not shown, for internal combustion engines.
- the relay 10 has a first housing part 13, designed as a coil housing for a feed coil of the relay 10.
- a relay cover is provided as the second housing part 16, which carries the electrical connecting elements to a starter battery and a starter motor.
- the first housing part 13 has at its left end shown in Figure la a cylindrical portion 19 which the represents the outer visible end of a relay opening, not shown, in which an electromagnetically excitable relay core 22 is inserted.
- the first housing part 13 has on its, the second
- End 25 facing housing part 16 has a flanged edge 28, through which second housing part 16 is fixedly connected to first housing part 13. This flanged edge 28 enables the first housing part 13 to be positively attached to the second housing part 16.
- the relay 10 has a longitudinal axis 29.
- the top view of the relay core 22 is shown in FIG.
- the relay 10 is usually fastened with a drive end shield of the starter device.
- the outer surface of the complete relay shown in FIGS. 1 a to 1 c is coated with a UV radiation-curing lacquer 43.
- the threaded or threaded bores 34 remain free of paint.
- FIG. 2 shows a partial section through the transition area or the area referred to as the joint, in which the second housing part 16 is firmly connected to the first housing part 13 by means of the flanged edge 28.
- an already mentioned joint 37 is present between the first housing part 13 and the second housing part 16. Untreated and thus uncoated, this joint 37 carries the risk that 37 foreign substances such as liquids (oil, water, ...) penetrate into the relay 10 through this joint due to the known capillary effect can and this can subsequently be destroyed (corrosion).
- the joint 37 is sealed at its end facing the outside of the relay 10 by means of a lacquer seal 40.
- the first housing part 13 usually consists of a corrosion-prone metal. Therefore, the first housing part 13 is painted.
- the lacquer seal 40 is first applied and then the first housing part 13 is provided with a lacquer layer.
- the paint layer 43 covers the housing part 13 at least from the paint seal 40 to the cylindrical ring-shaped section 19.
- a second embodiment is shown along the section line in Figure la.
- This exemplary embodiment differs from the exemplary embodiment according to FIG. 2 in that the first housing part 13 and the second housing part 16 are initially provided with the continuous lacquer layer 43 and are also provided with the lacquer seal 40 in the region of the outwardly directed end of the joint 37.
- the necessity of this sequence results from the fact that the lacquer layer 43 in the area of the outward end of the
- Joint 37 may no longer be contiguous and a reliable seal is therefore not guaranteed.
- FIG. 4 shows how and by what means the lacquer seal 40 is applied to the outward end of the joint 37.
- a first method is shown on the left side of FIG. In this case, a continuous lacquer strip is produced by means of a nozzle 46, which strikes the outward end of the Joint 37 is positioned.
- a continuous circumferential lacquer seal 40 is finally produced.
- a second exemplary embodiment for applying the lacquer seal 40 is shown on the right-hand side of FIG.
- the paint is also applied with a nozzle 46, the paint being conveyed at high pressure in this nozzle and thus being sprayable.
- the paint is sprayed on and forms a continuous paint seal 40 at the outwardly directed end of the joint 37 while rotating about the axis 52.
- FIG. 5 shows a section of the end of the relay 10 which has the cylindrical section 19. It is provided here that coating is also carried out on the annular end face 31 and in the region of the angle 55, the layer of paint on the annular end face 31 being thicker than at the angle 55.
- FIGS. 6a to 6e The individual process steps are shown in FIGS. 6a to 6e. According to FIG. 6a, it is provided in a step S LD to apply the uncured paint seal 40 to the outwardly directed end of the joint 37 as sprayed material and in a further step S H to harden the paint layer 37 or the paint seal 40 by means of ultraviolet radiation.
- a further exemplary embodiment of the method provides that the lacquer layer 43 is first applied in step S LSv before the uncured lacquer seal 40 is applied in step S LD . It becomes wet on the freshly painted relay 10 Paint seal 40 applied. After the application of the lacquer seal 40 in step S LD, it is provided that the entire lacquer coating, consisting of the lacquer layer 43 and the lacquer seal 40, is hardened in step S H.
- the method according to FIG. 6b leads to the exemplary embodiment according to FIG. 3.
- step S LD is carried out first, then lacquer layer 43 is applied in method step S LSn and then both lacquer layers are cured together in step S H.
- the method according to FIG. 6c leads to the exemplary embodiment according to FIG. 2.
- the application of a primer on the first housing 13 can precede the exemplary embodiment after the method steps according to FIG. 6b.
- FIG. 6e in which the method steps according to FIG. 6c are also preceded by method step S AG , after which a primer is applied beforehand.
- the hardening of the lacquer layer 43 and the lacquer seal 40 takes approximately 15 to 20 seconds. The seal is then firm. The layer thickness can be applied and cured in film thicknesses between 0.1 mm and 1 mm. The seal adheres to both
