The functional module includes a functional connection surface having a second opening, an engagement element disposed in the second opening and having a recess, and a sealing socket extending around the second opening. An edge of the recess forms a stop. The rigid component of the cap structure includes a frame extending around the second opening and a plug receptacle connected to the frame and having a locking hook. The soft component of the cap structure is disposed on the frame so as to face the functional connection surface. The engagement element is inserted into the plug receptacle such that the soft component abuts against the sealing socket and the locking hook engages within the recess.

Description

Detailed Description of the Invention

[0001] The present invention relates to an automation platform.

[0002] This patent application claims the priority of German Patent Application DE 10 2022 113 306.0 filed on May 25, 2022. The disclosure content thereof is incorporated herein by reference.

[0003] Modular automation platforms having a base module and a plurality of functional modules are known in the art. To protect the automation platform from moisture and / or dust, seals are used between the functional modules and the base module.

[0004] An object of the present invention is to provide an improved automation platform, an improved functional module for an automation platform, and an improved method for assembling an automation platform. These objects are solved by an automation platform having the configuration of each independent claim, a functional module for an automation platform, and a method for assembling an automation platform. Advantageous further embodiments are shown in the dependent claims.

[0005] The automated platform includes a base module, at least one functional module, and at least one connecting device for connecting the base module and the functional module. The base module includes a base housing having a base housing connection surface. The base housing connection surface includes at least one first opening. A protrusion around the first opening is formed within the base housing connection surface. The functional module includes a functional housing having a functional housing connection surface. The functional housing connection surface includes at least one second opening, at least one engaging element disposed in the second opening, and a sealing socket extending around the second opening. One wall of the engaging element includes a recess. An edge of the wall of the engaging element defining the recess forms a stop on the side of the recess facing away from the functional housing connection surface. The functional module includes a cap structure having a rigid component and a soft component disposed on the rigid component. The rigid component includes a frame extending around the second opening and at least one insertion receptacle connected to the frame. The soft component of the cap structure is disposed on a surface of the frame facing the functional housing connection surface and extends laterally around the second opening. A latching hook is disposed on one wall of the insertion receptacle. The engaging element is inserted into the insertion receptacle such that the soft component abuts against an outer wall of the sealing socket and the latching hook engages within the recess.When the functional module is placed on the base module in the open state of the connection device, the soft component of the cap structure portion arranges the hard component of the cap structure portion on the functional housing connection surface such that the locking hook of the insertion receptacle abuts against the stop of the engaging element, and the cap structure portion engages within the first opening in the base housing connection surface such that the frame of the hard component of the cap structure portion rests on the protrusion in the base housing connection surface, and the outer wall of the sealing socket is supported on the soft component of the cap structure portion such that the functional housing connection surface is separated from the base housing connection surface. When the connection device is in the closed state, the functional housing connection surface is pressed toward the base housing connection surface such that the soft component of the cap structure portion is radially pressed in the region between the protrusion in the base housing connection surface and the outer wall of the sealing socket, and the engaging element of the functional housing connection surface is pushed into the insertion receptacle of the hard component of the cap structure portion such that the locking hook of the insertion receptacle is separated from the stop of the engaging element.

[0006] Advantageously, a radial seal or a radial barrier against the ingress of dust, moisture or chemical substances is embodied by the soft component that is pressed in the region between the protrusion and the sealing socket on the base housing connection surface. One advantage of the radial seal is that when the functional module is placed on the base module, the radial seal is not initially pressed yet. When the frame of the cap structure is in contact with the protrusion on the base housing connection surface and the functional module has not yet been pressed onto the base module using the connecting device, the soft component is in an unpressed state. As a result, the functional housing connection surface is initially located at a position away from the base housing connection surface. This means that the frictional force during fitting of the functional module is reduced, and in particular, the functional module can be fitted with a particularly small force. This means that in the case of a large functional module having a plurality of radial seals, the force required for fitting onto the base module can be minimal. When the functional module is fitted, the locking hook of the insertion receptacle abuts against the stop of the engagement element.

[0007] Only when the connecting device is closed, the soft component is pushed into a predetermined position, and as a result, the sealing effect of the radial seal occurs. In this case, the cap structure is pushed into the base housing by only the distance or stroke remaining between the functional housing connection surface and the base housing connection surface after the functional module is fitted. Thereby, the locking hook moves away from the stop.

[0008] When the connection device is released, the soft component presses the functional module until the soft component expands and returns to a non-pressed form so that the stroke between the functional module and the base module returns to its original state. This facilitates the removal of the functional module. After the connection device is released, the locking hook abuts against the stop again. When the functional module is removed, the cap structure part is also removed together. Generally, this facilitates both the assembly of the functional module onto the base module and its removal. In both cases, the frictional force is reduced. This has the advantage that the wear of the radial seal is reduced.

[0009] In one embodiment, the functional housing connection surface includes at least one further engaging element arranged opposite the second opening and the engaging element. The wall of the further engaging element includes a further recess. A further edge of the wall of the further engaging element defining the further recess forms a further stop on the side of the further recess facing away from the functional housing connection surface. The rigid component includes at least one further insertion receptacle connected to the frame. A further locking hook is arranged on one wall of the further insertion receptacle. The further engaging element is pushed into the further insertion receptacle such that the soft component abuts against the outer wall of the sealing socket and the further locking hook engages within the further recess. When the functional module is placed on the base module with the connecting device open, the soft component of the cap structure is placed on the functional housing connection surface such that the further locking hook of the further insertion receptacle abuts against the further stop of the further engaging element. When the connecting device is closed, the further engaging element of the functional housing connection surface is pushed into the further insertion receptacle of the rigid component of the cap structure such that the further locking hook of the further insertion receptacle is spaced apart from the further stop of the further engaging element.

[0010] Advantageously, when the functional housing connection surface includes at least the further engagement element and the cap structure includes the further insertion receptacle, the cap structure is inserted onto the engagement element on the sides facing each other, so that the radial seal is pressed more evenly. By connecting at least two locking hooks to the functional housing connection surface, it becomes possible to remove the functional module evenly. This is because when the functional module is separated from the base module, the cap structure can be removed together, at least on the sides facing each other of the second opening.

[0011] In one embodiment, the sealing socket tapers at least partially from the functional housing connection surface. The soft component of the cap structure lies in contact with the outer wall of the sealing socket in the region of the tapered portion. Advantageously, the radial seal is pressed more effectively by the tapered sealing socket.

[0012] In one embodiment, the sealing socket is connected to the engagement element and, in the region of the engagement element, is formed by the engagement element, or the sealing socket extends laterally around the engagement element.

[0013] In one embodiment, an additional soft component is arranged between the functional housing connection surface and the side wall of the functional housing. When the functional module is placed on the base module and the connection device is open, the additional soft component is arranged on the base housing connection surface, and when the connection device is closed, the additional soft component is pressed towards the base housing connection surface. Advantageously, the additional soft component forms an axial seal or an axial barrier against the ingress of dust, moisture, or chemical substances. In addition, a radial barrier is formed in the region between the side wall of the functional housing and the functional housing connection surface.

[0014] In one embodiment, the side wall of the functional housing includes additional protrusions on the inner surface of the functional housing. When the functional module is placed on the base module, when the connecting device is open, the additional soft component lies in contact with the additional protrusions, and when the connecting device is closed, the additional soft component is pressed towards the additional protrusions. Advantageously, an axial seal or axial barrier is formed by the additional soft component.

[0015] In one embodiment, the functional housing connection surface includes additional protrusions protruding in the direction of the side wall of the functional housing. The additional protrusions engage with the additional soft component. When the functional module is placed on the base module with the connecting device open, the additional soft component lies in contact with the additional protrusions, and when the connecting device is closed, the additional soft component is pressed towards the additional protrusions. Advantageously, both an axial seal or axial barrier and a radial seal or radial barrier are formed by the additional protrusions. The axial barrier is formed on the side of the functional housing connection surface facing the base housing connection surface in the region of the additional protrusions. The radial barrier is formed at the edge of the functional housing connection surface.

[0016] In one embodiment, the functional housing connection surface is rigidly connected to the side wall of the functional housing. Further soft components are arranged in a groove formed on the functional housing connection surface. When the functional module is placed on the base module, when the connection device is open, the additional soft component is arranged on the base housing connection surface, and when the connection device is closed, the additional soft component is pressed towards the base housing connection surface. Advantageously, an axial seal or an axial barrier is formed by the additional soft component.

[0017] The functional module for the automation platform includes a functional housing having a functional housing connection surface. The functional housing connection surface includes at least one second opening, at least one engaging element disposed in the second opening, and a sealing socket extending around the second opening. One wall of the engaging element includes a recess. The edge of the wall of the engaging element that defines the recess forms a stop on the side of the recess facing away from the functional housing connection surface. The functional module includes a cap structure having a rigid component and a soft component disposed on the rigid component. The rigid component includes a frame extending around the second opening and at least one insertion receptacle connected to the frame. The soft component of the cap structure is disposed on the surface of the frame facing the functional housing connection surface and extends laterally around the second opening. A locking hook is disposed on one wall of the insertion receptacle. The engaging element is inserted into the insertion receptacle such that the soft component abuts against the outer wall of the sealing socket and the locking hook engages within the recess. The soft component of the cap structure is arranged on the functional housing connection surface such that the locking hook of the insertion receptacle contacts the stop of the engaging element. The functional module can be placed on the base module such that when the connection device is open, the frame of the rigid component of the cap structure rests on the protrusion in the base housing connection surface, the cap structure engages within the first opening in the base housing connection surface, and the outer wall of the sealing socket is supported on the soft component of the cap structure such that the functional housing connection surface is spaced apart from the base housing connection surface.When the connection device is closed, the functional housing connection surface is pressed toward the base housing connection surface such that the soft component of the cap structure portion is radially pressed in the region between the protrusion on the base housing connection surface and the outer wall of the sealing socket, and the engaging element of the functional housing connection surface is pushed into the insertion receptacle of the rigid component of the cap structure portion such that the locking hook of the insertion receptacle is separated from the stop of the engaging element.

[0018] In one embodiment, the functional housing connection surface includes at least one additional engaging element disposed opposite the second opening and the engaging element. The wall of the additional engaging element includes an additional recess. The additional edge of the wall of the additional engaging element that defines the additional recess forms an additional stop on the side of the additional recess facing away from the functional housing connection surface. The rigid component includes at least one additional insertion receptacle connected to the frame. An additional locking hook is disposed on one wall of the additional insertion receptacle. The additional engaging element is inserted into the additional insertion receptacle such that the soft component of the cap structure portion abuts against the outer wall of the sealing socket and the additional locking hook engages within the additional recess. The soft component of the cap structure portion is disposed on the functional housing connection surface such that the additional locking hook of the additional insertion receptacle abuts against the additional stop of the additional engaging element of the cap structure portion. When the connection device is closed, the additional engaging element of the functional housing connection surface is pushed into the additional insertion receptacle of the rigid component of the cap structure portion such that the additional locking hook of the additional insertion receptacle is separated from the additional stop of the additional engaging element.

[0019] In one embodiment, the sealing socket is at least partially tapered starting from the functional housing connection surface. The soft component of the cap structure lies in contact with the outer wall of the sealing socket in the region of the tapered portion.

[0020] In one embodiment, the sealing socket is connected to the engagement element and, in the region of the engagement element, is formed by the engagement element or the sealing socket extends laterally around the engagement element.

[0021] In one embodiment, an additional soft component is arranged between the functional housing connection surface and the side wall of the functional housing. When the functional module is placed on the base module, when the connecting device is open, the additional soft component is arranged on the base housing connection surface, and when the connecting device is closed, the additional soft component is pressed towards the base housing connection surface.

[0022] In one embodiment, the side wall of the functional housing includes a further protrusion on the inner surface of the functional housing. When the functional module is placed on the base module, when the connecting device is open, the additional soft component abuts against the additional protrusion, and when the connecting device is closed, the additional soft component is pressed towards the additional protrusion.

[0023] In one embodiment, the functional housing connection surface includes an additional protrusion protruding in the direction of the side wall of the functional housing. The additional protrusion fits into the additional soft component.

[0024] In one embodiment, the functional housing connection surface is rigidly connected to the side wall of the functional housing. Further soft components are arranged in the grooves formed on the functional housing connection surface. When the functional module is placed on the base module, when the connection device is open, the additional soft component is arranged on the base housing connection surface, and when the connection device is closed, the additional soft component is pressed towards the base housing connection surface.

[0025] In a method for assembling an automation platform, the cap structure engages with the first opening in the base housing connection surface such that the frame of the rigid component of the cap structure rests on the protrusion in the base housing connection surface, and the functional housing connection surface is spaced from the base housing connection surface, and the outer wall of the sealing socket is supported on the soft component of the cap structure such that the functional module is placed on the base module. The connection device is closed, but at this time, the functional housing connection surface is pressed towards the base housing connection surface such that the soft component of the cap structure is radially pressed in the region between the protrusion in the base housing connection surface and the outer wall of the sealing socket, and the locking hook of the insertion receptacle is spaced from the stop of the engaging element, and the engaging element of the functional housing connection surface is pushed into the insertion receptacle of the rigid component of the cap structure.

[0026] In one embodiment, the connection device is released. At this time, the functional housing connection surface is spaced from the base housing connection surface, and the soft component presses the outer wall of the sealing socket such that the locking hook abuts against the stop of the engaging element.

[0027] An automation platform and a method for assembling the automation platform will be described in detail below together with schematic diagrams: Figure 1: Perspective view of an automation platform having a base module and functional modules; Figure 2: Cross-sectional view of the automation platform of Figure 1; Figure 3: Further cross-sectional view of the automation platform of Figure 1; Figure 4: Perspective view of a functional module of the automation platform; Figure 5: Perspective view of a further functional module of the automation platform; Figure 6: Cross-sectional view of the functional module of Figure 5; Figure 7: Cross-sectional view of the functional module and the base module in the unassembled state of the automation platform; Figure 8: Cross-sectional view of Figure 7 in a state where the functional module is attached onto the base module; Figure 9: Cross-sectional view of Figure 8 in a state where the functional module is pressed onto the base module.

[0028] Figure 1 is a schematic perspective view of an exemplary automation platform 1. The automation platform 1 includes electrical components and / or electronic components and functions as a distribution system for field devices (e.g., sensors and actuators). The automation platform 1 may be used, for example, in production machines. The automation platform 1 may replace a control cabinet.

[0029] The automation platform 1 has a modular design. The automation platform 1 includes a base module 2 and functional modules 3. As an example, the automation platform 1 includes a total of four functional modules 3. The automation platform 1 may include various numbers of functional modules 3, but the automation platform 1 includes at least one functional module 3. By way of example only, the functional modules 3 have different sizes.

[0030] The first functional module 4 is exemplarily embodied as an industrial PC module. The industrial PC module, also referred to as the upper module, is embodied to control other functional modules 3.

[0031] The second functional module 5 is exemplarily embodied as a system module. The system module includes a connection part 6 for supplying system voltage, a fuse (not shown in FIG. 1) for protecting the system voltage, and a main switch 7 for switching the system voltage.

[0032] The third functional module 8 is exemplarily embodied as a bus coupler. The bus coupler includes two exemplary connection parts 9, each having a data input part and a data output part. Data communication may be performed based on, for example, the Ethernet or EtherCAT protocol. However, data communication is not limited to the above-mentioned protocols. In addition to the data input part and the data output part, each connection part 9 of the bus coupler may include a voltage input part and a voltage output part for coupling and transferring voltage. In this case, data communication and voltage may each be supplied via the common connection part 9, but this is not necessarily required. Instead, separate voltage connection parts may be provided for supplying and transferring voltage.

[0033] Alternatively, the third functional module 8 may be embodied as a relay module for directly switching voltage. For example, the relay module may be used to supply voltage to a fan, an electric heater, lighting, and an electric motor (e.g., a three-phase asynchronous motor). Alternatively, the third functional module 8 may be embodied as a servo amplifier or a frequency converter.

[0034] The fourth functional module 10 of the control cabinet system 1 is exemplarily embodied as an I / O module, and the I / O module includes a connection part 11 having an input part and an output part for analog data and / or digital data. A field device (for example, an actuator and / or a sensor) can be controlled via the I / O module.

[0035] The base module 2 includes a base housing 12 having a base housing connection surface 13. Each of the functional modules 3 includes a functional housing 14 having a functional housing connection surface 15. In the assembled state of the automation platform 1, each of the functional modules 3 is arranged with the functional housing connection surface 15 on the base housing connection surface 13, and is pressed onto the base housing connection surface 13 using respective connecting devices 16.

[0036] The connecting device 16 is embodied to connect the functional module 3 to the base module 2. In an exemplary embodiment of the automation platform 1, each of the connecting devices 16 includes a plurality of screws for each functional module 3, and the functional module 3 is fixed to the base housing connection surface 13 using the plurality of screws. The plurality of screws extend through the functional module 3. To fit the plurality of screws, each of the connecting devices 16 on the base housing connection surface 13 includes, for example, a blind hole having a thread. Also, the connecting device 16 may be embodied in another way. For example, the connecting device 16 may be embodied in the form of a locking structure so that the functional module 3 can be arranged on the base housing connection surface 13 by locking.

[0037] FIG. 2 schematically shows a cross-sectional view of the automation platform 1 of FIG. 1 along a plane spanned by a first direction 17 and a second direction 18, the plane extending along the functional module 3 and perpendicular to the base housing connection surface 13. A cross-section through the fourth functional module 10 is shown merely by way of example. However, the following description applies mutatis mutandis to all the functional modules 3. The same elements are assigned the same reference numerals as in FIG. 1.

[0038] The base module 2 is intended to receive data from the functional module 3 and to transmit data to the functional module 3. For this purpose, the base module 2 includes a base connection element 20 arranged within the base housing 12. Each of the functional modules 3 includes a functional connection element 21 arranged within the functional housing 14. In the assembled state of the automation platform 1, one base connection element 20 and one functional connection element 21 engage with each other to form an interface between the base module 2 and the functional module 3. Data can be exchanged between the base module 2 and the fourth functional module 10 via the said interface. A voltage can be supplied to the fourth functional module 10 by the base module 2.

[0039] The base housing 12 includes a first opening 22 on the base housing connection surface 13. The first openings 22 are each arranged within the area of the base connection element 20. In each case, the base connection element 20 and the first opening 22 form a slot for the functional module 3. The base connection element 20 can be embodied as either a built-in plug or a built-in socket. As an example, the base connection element 20 in FIG. 2 is embodied as a built-in socket. Any number of contact openings of the base connection element 20 can be used.

[0040] The functional housing 14 of the fourth functional module 10 includes a second opening 23 on its functional housing connection surface 15. In the assembled state of the automation platform 1, when the functional housing 14 abuts against the base housing connection surface 13 of the base housing 12 by the functional housing connection surface 15, the first opening 22 and the second opening 23 are arranged such that one is on top of the other. The functional connection element 21 is arranged within the region of the second opening 23 and protrudes from the functional housing 14. The functional connection element 21 can be embodied as either a built-in plug or a built-in socket. As an example, the functional connection element 21 of the fourth functional module 10 is embodied as a built-in plug. Any number of contact pins of the functional connection element 21 can be used.

[0041] The functional housing 14 may include any number of second openings 23 and functional connection elements 21 arranged within the region of the second opening 23. For example, the second functional module 5 in FIG. 1 extends over a total of six slots of the base module 2. The second functional module 5 includes, as an example, only four second openings 23 and two functional connection elements 21. For the two first openings 22 of the base module 2, the second functional module 5 is not provided with a second opening 23. On the other hand, of the four second openings 23, two are not provided with a functional connection element 21. In contrast, the first functional module 4 and the third functional module 8 each extend, for example, over four slots of the base module 2, and the first functional module 4 and the third functional module 8 each include two functional connection elements 21, and the two functional connection elements 21 are arranged within the region of one of the two first openings 23. The second opening 23 where the functional connection element 21 is not arranged may be used to ventilate the second functional module 5 or any functional module 3, and may also serve to guide the functional module 3 during assembly.

[0042] If the functional module 3 extends over a plurality of slots of the base module 2 or over the first opening 22 and includes a smaller number of second openings 23 and / or functional connection elements 21, the slots of the base module may be omitted. That is, at least the base connection element 20 may be omitted, and in some cases, the first opening 22 may also be omitted. For example, in the case of the second functional module 5, a total of four slots of the base module 2 may be omitted. Instead of omitting the first opening 22 when the base connection element 20 is not provided, the first opening 22 may be sealed by a plug 57. Such a plug 57 may be made of a solid material having, for example, a circumferential groove and an O-ring seal disposed within the circumferential groove. The plug 57 may enclose the base connection element 20 of the slot. The plug 57 may be inserted into an unused slot of the base module 2 before assembling the functional module 3 to seal the unused slot. The aforementioned O-ring seal is radially compressed by positive locking with the base housing 12. The functional housing connection surface 15 of the attached functional module 3 may be spaced from the plug 57, or may abut against the plug 57 and, optionally, exert pressure on the plug 57 in the attached state.

[0043] For data exchange with the functional module 3, the base module 2 may include an interface unit within the base housing 12. The interface units may be connected to each other via a data bus. The interface unit (not shown in FIGS. 1 and 2 for clarity) may be embodied, for example, as an application-specific integrated circuit (ASIC). The connection unit may be, for example, part of the circuit board of the base module 2 (which is also not shown). For communication with the functional module 3, each interface unit is connected to the base connection element 20. And the functional connection element 21 of the functional module 3 is connected to a component arranged within the functional housing 14. This may be, for example, a circuit board 24.

[0044] FIG. 3 schematically shows a cross-sectional view of the automation platform 1 of FIG. 1 along a plane spanned by the second direction 18 and the third direction 19, which extends perpendicular to the base housing connection surface 13 and perpendicular to the first direction 17. Cross-sections through the second functional module 5, the third functional module 8, and the fourth functional module 10 are shown as merely illustrative. The same reference numerals as in FIGS. 1 and 2 are assigned to the same elements.

[0045] The functional module 3 includes various types of functional housings 14. The second functional module 5 and the third functional module 8 each include a functional housing 14. In the said functional housing 14, a functional housing connection surface 15 is rigidly (rigidly, firmly) connected to the side wall 25 of the functional housing 14. This also applies to the first functional module 4 which is not shown in Figure 1. In contrast, the functional housing connection surface 15 of the fourth functional module 10 is not rigidly connected to the side wall of the functional housing 14. Instead, the functional housing connection surface 15 of the fourth functional module 10 is embodied as a separate bottom plate 26. Conversely, it is also possible that the first functional module 4, the second functional module 5, and the third functional module 8 each include a separate bottom plate 26, and the functional housing connection surface 15 of the fourth functional module 10 is rigidly connected to the side wall 26 of the functional housing 14.

[0046] In a deformed form of the functional housing 14 where the functional housing connection surface 15 is rigidly connected to the side wall 25, each of the functional housings 14 includes a cap 27. The cap 27 enables access to the area inside the functional housing 14. For example, by opening the cap 27, the components inside the functional housing 14 can be arranged or replaced. Merely by way of example, the portion of the side wall 25 rigidly connected to the functional housing connection surface 15 and the cap 27 can be separated from each other at an angle along the diagonal of the substantially opposite faces of the functional housing 14, so that the functional housings 14 of the second functional module 5 and the third functional module 8 are embodied. This can also be seen in Figure 1. In a variant having a separate bottom plate 26, since the bottom plate 26 can be removed, the functional housing 14 is accessible.

[0047] The automation platform 1 is based on the idea of an improved sealing concept. This will be explained in more detail. The automation platform 1 needs to be protected, for example, from the ingress of dust, moisture, and chemicals. For this purpose, the automation system 1 includes a radial seal 28 arranged between the functional module 3 and the base module 2. The radial seal 28 is embodied in the same way for each type of functional module 4, 5, 8, 10.

[0048] The automation platform 1 further includes a first axial seal 29 and a second axial seal 30. The first functional module 4, the second functional module 5, and the third functional module 8 each include a functional housing connection surface 15 rigidly connected to the side wall 25 of the functional housing 14. In each of these cases, a first soft component 31 is arranged in a groove 32 formed on the functional housing connection surface 15. When the first functional module 4, the second functional module 5, and the third functional module 6 are placed on the base module 2 and the connecting device 16 is open, the first soft component 31 is arranged on the base housing connection surface 13. When the connecting device 16 is closed, the first soft component 31 is each pressed towards the base housing connection surface 13, forming a first axial barrier against dust, moisture, or chemicals between the base housing connection surface 13 and the functional housing connection surface 15.

[0049] Figure 4 schematically shows a perspective view of the third functional module 8. Only the third functional module 8 is shown as an example. However, the following description is appropriately applied to all functional modules 3 having the first axial seal 29. Figure 4 further shows an enlarged view of a part of the functional housing connection surface 15 having the first axial seal 29. The same elements are identified by the same reference numerals as in the drawings described above.

[0050] The first soft component 31 disposed within the groove portion 32 is exemplified and embodied as an O-ring. Alternatively, the first soft component 31 may be disposed within the groove portion 32 using a molding process, for example, an injection molding process. The groove portion 32 and the first soft component 31 laterally surround the second opening 23 at the functional housing connection surface 15. Similarly, the groove portion 32 and the first soft component 31 laterally surround all the functional connection elements 21 and all the radial seals 28.

[0051] The first axial seal 29 includes a retaining knob (protrusion) 33 for improving the fixation of the first soft component 31 within the groove portion 32. The retaining knob 33 is formed by the first soft component 31. The retaining knobs 33 are exemplified as being alternately arranged on opposite faces of the first soft component 31, but the retaining knobs 33 may be arranged differently. However, the retaining knobs 33 may be omitted.

[0052] FIG. 5 schematically shows a perspective view of the fourth functional module 10. Here, the fourth functional module 10 is shown in both an assembled state and a non-assembled state. FIG. 5 shows only the fourth functional module 10 as an example for explaining the radial seal 28 of the automation platform 1. For this reason, the following description applies to all of the functional module 3 and its radial seals 28 with respect to the base module 2. The same elements are identified using the same reference numerals as in the previously described drawings.

[0053] The functional housing connection surface 15 includes at least one engagement element 34 disposed in the second opening 23 and a sealing socket 35 extending around the second opening 23. In an exemplary embodiment of the functional housing 14 of FIG. 5, the functional housing connection surface 15 includes at least one further engagement element 36 disposed opposite the second opening 23 and the engagement element 34. However, the functional housing connection surface 15 may include any number of engagement elements 34, 36 disposed in the second opening 23. That is, for each second opening 23, at least one engagement element 34, 36 is provided. When the functional housing connection surface 15 of the functional module 3 includes a plurality of second openings 23, at least one engagement element 34 is disposed in the second opening 23 in each case.

[0054] The shapes of the engagement elements 34, 36 are, for example, cylindrical. Since the engagement elements 34, 36 open on a surface facing away from the functional housing connection surface 15, the functional housing 14 is accessible. Thereby, cooling air is exchanged between the inside of the base housing 14 and the inside of the functional housing 14. For this reason, the engagement elements 34, 36 may also be referred to as ventilation nozzles. However, the engagement elements 34, 36 do not necessarily have to be configured to be embodied as open ventilation nozzles. The engagement elements 34, 36 may have different shapes. What is important is that the engagement elements 34, 36 project away from the functional housing 14 at the functional housing connection surface 15.

[0055] The sealing socket 35 extends laterally around the second opening 23 and protrudes away from the functional housing 14 at the functional housing connection surface 15. In an exemplary embodiment of the functional housing 14, the sealing socket 35 is rigidly connected to the engaging elements 34, 35 and is formed by the engaging elements 34, 36 in the region of the engaging elements 34, 36. In the region of the engaging elements 34, 36, the sealing socket 35 extends on the surface of the engaging elements 34, 36 facing away from the second opening 23. In an alternative embodiment, the sealing socket 35 further extends laterally around the engaging elements 34, 36. In this case, the sealing socket 35 is not connected to the engaging elements 34, 36 and is not partially formed by the engaging elements 34, 36.

[0056] The functional module 3 further includes a cap structure 37, and the cap structure 37 has a rigid component 38 and a second soft component 39 disposed on the rigid component 38. The rigid component 38 includes a frame 40 surrounding the second opening 23 and at least one insertion receptacle 41 connected to the frame 40. The second soft component 39 of the cap structure 37 is disposed on the surface of the frame 40 facing the functional housing connection surface 15 and extends laterally around the second opening 23. The radial seal 28 is formed by the second soft component 39.

[0057] The second soft component 39 may be disposed on the hard component 38 using a molding process (e.g., injection molding). In this case, the hard component 38 and the second soft component 39 are joined to each other. That being said, the second soft component 39 may alternatively be embodied as an O-ring. However, according to the material-locking connection between the hard component 38 and the second soft component 39, when assembling the functional module 3 or the automation platform 1, there is an advantage that it is not necessary to dispose the second soft component 39 on the hard component 38.

[0058] Also, a plurality of insertion receptacles 41 may be provided. It is advantageous that the number of insertion receptacles 41 of the cap structure portion 37 is the same as the number of engagement elements 34, 36 of the functional housing connection surface 15. For this reason, the cap structure portion 37 of the exemplary embodiment according to FIG. 5 includes an additional insertion receptacle 42. The additional insertion receptacle 42 is connected to the frame 40 and is disposed on the side of the frame 40 opposite to the insertion receptacle 41. The insertion receptacles 41, 42 are embodied to open on a surface facing away from the frame 40. As a result, the insertion receptacles 41, 42 and the engagement elements 34, 36 can each be used as ventilation nozzles. That being said, this is not absolutely necessary.

[0059] When assembling the functional module 3, the functional housing connection surface 15 is arranged on the functional housing 14 such that the functional connection element 21 protrudes from the functional housing 14 through the second opening 23 in the functional housing connection surface 15. As a result, the functional connection element 22 can be guided through the first opening 22 in the base housing connection surface 13 and connected to the base connection element 20. When assembling the functional module 3, the insertion receptacles 41, 42 are inserted onto the functional housing connection surface 15 such that the engagement elements 34, 36 are each pushed into and engaged with the insertion receptacles 41, 42. For this reason, the insertion receptacles 41, 42 have a geometric shape similar to that of the engagement elements 34, 36. On one wall of each insertion receptacle 41, 42, locking hooks 43, 44 are arranged. The locking hook 43 of the insertion receptacle 41 and the further locking hook 44 of the further insertion receptacle 44 are arranged on the opposite surfaces of the insertion receptacles 41, 42.

[0060] The recesses 45, 46 are arranged on one wall of each engagement element 34, 36. The recess 45 of the engagement element 34 and the further recess 46 of the further engagement element 36 are arranged on the opposite surfaces of the engagement elements 34, 36 facing each other. If only one engagement element 34 is provided and correspondingly only one insertion receptacle 41 is provided, the recess 45 and the locking hook 43 are each arranged on the surface of the engagement element 34 or the insertion receptacle 41 facing the second opening 23. The engagement elements 34, 36 are inserted into the insertion receptacles 41, 42 such that the second soft component 39 abuts against the outer wall of the sealing socket 35 and the locking hooks 43, 44 of the insertion receptacles 41, 42 are each engaged within the recesses 45, 46 of the engagement elements 34, 36.

[0061] In each case, the recesses 45, 46 are defined by the edges of the walls of the engagement element. In each case, the edges form stops 47, 48 on the side of the recesses 45, 16 facing away from the functional housing connection surface 15.

[0062] When the functional module 3 is placed on the base module 2 and the connecting device 16 between the functional housing 14 and the base housing 12 is open, the locking hooks 43, 44 of the insertion receptacles 41, 42 respectively abut against the stops 47, 48 of the engaging elements 34, 36, and the rigid component 38 of the cap structure 38 is disposed on the functional housing connection surface 15 by the second soft component 39 of the cap structure 37. The locking hook 43 abuts against the stop 47. The other locking hook 44 abuts against the other stop 48.

[0063] FIG. 6 shows a schematic cross-sectional view of the automation platform 1 shown in FIG. 3. However, only the fourth functional module 10 and the base module 2 are shown. The fourth functional module 10 is shown in more detail in FIG. 6 than in FIG. 3. In FIG. 6, only the fourth functional module 10 is shown as an example to more specifically explain the principle of the radial seal 28 of the automation platform 1. Nevertheless, the automation platform 1 includes at least one such radial seal 28 disposed between the base module 2 and the functional module 3 for each of the other functional modules 10. An enlarged view of the region of the radial seal 28 is also shown in FIG. 6. The same elements are given the same reference numerals as in the drawings described above.

[0064] On the base housing connection surface 13, a protrusion 49 is formed around the first opening 22. The protrusion 49 is disposed on the surface of the base housing connection surface 13 facing the inside of the base housing 12. The protrusion 49 can also be referred to as a seating portion. When the functional module 3 is placed on the base module 2 with the connection device 16 open, the cap structure portion 37 engages with the first opening 22 in the base housing connection surface 13 such that the frame 40 of the rigid component 38 of the cap structure portion 37 rests on the protrusion 49 in the base housing connection surface 13, and the outer wall of the sealing socket 35 is supported on the second flexible component 39 of the cap structure portion 37 so that the functional housing connection surface 15 is spaced apart from the base housing connection surface 13. This is not shown in FIG. 6. This is because in this case, the automation platform 1 is shown in the assembled state with the connection device 16 closed. The distance between the base housing connection surface 13 and the functional housing connection surface 15 when the functional module 3 is attached to the base module 2 and the connection device 16 is open can also be referred to as the stroke. The stroke and its effects will be described in more detail in the description of the method for assembling the automation platform 1 shown in FIGS. 7 to 9. When the slot is sealed by the plug 57, the protrusion 49 can act as a stop or depth limiter for the plug 57.

[0065] As shown in FIG. 6, when the connection device 16 is closed, the functional housing connection surface 15 is pressed toward the base housing connection surface 13 such that the second flexible component 39 of the cap structure portion 37 is radially pressed in the region between the protrusion 49 in the base housing connection surface 13 and the outer wall of the sealing socket 35, and the engaging elements 34, 36 of the functional housing connection surface 15 are each inserted into the insertion receptacles 41, 42 of the rigid component 38 of the cap structure portion 37 such that the locking hooks 43, 44 of the insertion receptacles 41, 42 are each spaced apart from the stops 47, 48 of the engaging elements 34, 36.

[0066] The second soft component 39 lies horizontally in contact with the sealing socket 35. As a result, a first radial barrier against dust, moisture, or chemicals is formed. As in the exemplary embodiment of FIG. 6, the sealing socket 35 may be embodied to taper at least partially from the functional housing connection surface 15. The second soft component 39 of the cap structure portion 37 lies horizontally in contact with the outer wall of the sealing socket 35 in the region of the tapered portion. Thereby, the second soft component 39 is pressed more effectively. Further, the second soft component 39 contacts, on the protrusion 39, the wall defining the first opening 22 at the base housing connection surface 13. Thereby, a second radial barrier is formed. In FIG. 6, for the explanation of the sealing effect, the second seal 28 is shown in both the compressed state and the uncompressed state. In FIG. 6, the portion of the second soft component 39 overlapping the sealing socket 35 shows a geometric shape of the second soft component 39 in the uncompressed state. In the compressed state, the second soft component 39 extends only up to the sealing socket 35.

[0067] In the fourth functional module 10, the functional housing connection surface 15 is embodied as a separate bottom plate 26. For this reason, a second axial seal 30 is provided. The third soft component 50 is disposed between the functional housing connection surface 15 and the side wall 25 of the functional housing 14. For example, the third soft component 50 may be disposed on the edge 51 of the functional housing connection surface 15 using a molding process (e.g., an injection molding process). Alternatively, the third soft component 50 may be attached to the edge 51 of the functional housing connection surface 15.

[0068] When the fourth functional module 10 is placed on the base module 2 with the connecting device 16 open, the third soft component 50 is disposed on the base housing connection surface 13 and is pressed toward the base housing connection surface 13 when the connecting device 16 is closed. Thereby, a second axial barrier against dust, moisture or chemical substances is formed. Further, the third soft component 50 lies in contact with the side wall 25 of the functional housing 14. Thereby, a third radial barrier is formed.

[0069] According to an exemplary embodiment of the fourth functional module 10, the side wall 25 of the functional housing 14 includes a further protrusion 52 on the inner surface of the functional housing 14. As an example, a groove-shaped recess 53 is formed between the further protrusion 52 and the side wall 25, but this may be omitted. When the fourth functional module 10 is placed on the base module 2 with the connecting device 16 open, the third soft component 50 abuts against the further protrusion 52. When the connecting device 16 is closed, the third soft component 50 is pressed toward the further protrusion 52. Thereby, a third axial barrier is formed. However, the further protrusion 52 is not necessarily provided and may be omitted. In FIG. 6, for the explanation of the sealing effect, the third soft component 50 is also shown in both the compressed state and the non-compressed state. In FIG. 6, the portion of the third soft component 50 overlapping the protrusion 52 shows the non-compressed state.

[0070] The functional housing connection surface 15 further includes an additional protrusion 54 that protrudes in the direction of the side wall 25 of the functional housing 14. The additional protrusion 54 fits into (engages with) the third soft component 50. When the fourth functional module 10 is placed on the base module 2 with the connecting device 16 open, the third soft component 50 abuts against the additional protrusion 54. When the connecting device 16 is closed, the third soft component 50 is pressed towards the additional protrusion 54. Thereby, a fourth axial barrier and a fifth axial barrier are formed. The fourth axial barrier is formed on the side of the functional housing connection surface 15 facing away from the base housing connection surface 13. The fifth axial barrier is formed on the side of the functional housing connection surface 15 facing the base housing connection surface 13. Further, a third radial barrier is formed in the region where the third soft component 50 is pressed towards the edge 51 of the functional housing connection surface 15 when the functional housing connection surface 15 is connected to the side wall 25 of the functional housing.

[0071] Figures 7 to 9 schematically show the state over time in the situation of the process for assembling the automation platform 1. Figures 7 to 9 correspond to the cross-sectional views of Figure 2 in each case. The fourth functional module 10 is shown as just an example for explaining the effect of the radial seal 28 during assembly.

[0072] Figure 7 shows a state where the functional module 3 and the base module 3 are separated from each other. In this case, the hard component 38 of the cap structure 37 is arranged on the functional housing connection surface 15 by the second soft component 39 of the cap structure 37 such that the locking hooks 43, 44 of the insertion receptacles 41, 42 abut against the stops 47, 48 of the engagement elements 34, 36 respectively.

[0073] Figure 8 shows the state after the functional module 3 is placed on the base module 2, following Figure 7. However, the connecting device 16 is in an open state. Therefore, the functional module 3 is merely in contact with the base module 2 and has not yet been pressed onto the base module 2.

[0074] Also in this case, the locking hooks 43, 44 of the insertion receptacles 41, 42 abut against the stops 47, 48 of the engagement elements 34, 36 respectively, and the rigid component 38 of the cap structure 37 is disposed on the functional housing connection surface 15 by the second soft component 39 of the cap structure 37. This is because the connecting device 16 is open, so the second soft component 39 has not yet been pressed.

[0075] The cap structure 37 engages with the first opening 22 in the base housing connection surface 13 such that the frame 40 of the rigid component 38 of the cap structure 37 rests on the protrusion 49 in the base housing connection surface 13, and the outer wall of the sealing socket 35 is supported on the second soft component 39 of the cap structure 37 so that the functional housing fitting surface 15 is spaced apart from the base housing connection surface 13. This distance can also be referred to as the stroke 55.

[0076] Figure 8 also shows an enlarged view of the area of the locking hook 43 that abuts against the stop 47. This enlarged view further shows the stroke 55 between the base housing connection surface 13 and the functional housing connection surface 15. The stroke 55 is also a result of the second soft component 39 not being pressed in this state.

[0077] As a result, the second soft component 39 remains in an unpressed state during the insertion or positioning of the functional module 3. As a result, the functional module 3 can be positioned almost without friction and without applying force thereto.

[0078] FIG. 9 shows the state after the connection device 16 is closed and the functional module 3 is connected to the base module 2, which temporally follows FIG. 8. Similar to FIG. 6, in FIG. 9, the second seal 28 is shown in the compressed state and the uncompressed state. Therefore, FIG. 9 also shows the portion of the second soft component 39 that overlaps with the sealing socket 35, and this portion shows the geometric shape of the second soft component 39 in the uncompressed state.

[0079] By closing the connection device 16, the functional housing connection surface 15 is pressed radially toward the base housing connection surface 13 such that the second soft component 39 of the cap structure portion 37 is pressed in the region between the protrusion 49 on the base housing connection surface 13 and the outer wall of the sealing socket 35. The engaging elements 34, 36 of the functional housing connection surface 15 are inserted into the insertion receptacles 41, 42 of the rigid component 38 of the cap structure portion 37 such that the locking hooks 43, 44 of the insertion receptacles 41, 42 are each separated from the stops 47, 48 of the engaging elements 34, 36. FIG. 9 shows an enlarged view of the region of the distance 56 up to one of the plurality of locking hooks 44 and the associated stop 48. Therefore, the functional module 3 is simply pulled by the connection device 16 to the terminal position, and the functional housing connection surface 15 contacts the base housing connection surface 13. Only then is the sealing effect produced by the radial seal 28. Thereby, the functional module 3 can be fitted with a little effort. Thereby, the insertion or attachment of the particularly large functional module 3 having a plurality of functional connection elements 21 and the radial seal 28 can be simplified. In addition, the wear of the radial seal 28 during assembly is reduced.

[0080] When the connection device 16 is opened or released again, the second soft component 39 presses the outer wall of the sealing socket 35 such that the functional housing connection surface 15 is separated from the base housing connection surface 13 and the locking hooks 43, 44 abut against the stops 47, 48 of the engaging elements 34, 36. When the pressure on the second soft component generated by the connection device 16 is removed, the functional housing 14 is pressed by the second soft component 39 into a non-attached state, and there is no longer a large friction between the functional module 3 and the base module 2. When the connection device 16 is released, the second soft component 39 already presses the functional module 3 with a component of force, and as a result, the release of the functional module is supported and can be performed with a small amount of force. Only then can the cap structure 37 be removed together via the locking hooks 43, 44. As a result, the functional module 3 can be more easily removed from the base module 2 by the stroke 55. Since the locking hooks 43, 44 are initially separated from the stops 47, 48, the cap structure 37 initially remains in a predetermined position, but the functional module 3 can already be in a separated state according to the stroke 55.
