Automation platform

Abstract

The base module includes a base connection surface having a first opening. A protrusion is formed around the first opening. 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. When the connection device between the functional module and the base module is open, the soft component disposes the rigid component on the functional connection surface such that the locking hook contacts the stop, and the sealing socket is supported on the soft component such that the plurality of connection surfaces are spaced apart from each other. When the connection device is closed, the plurality of connection surfaces are pressed against each other such that the soft component is pressed between the protrusion and the sealing socket, and the engagement element is pushed further into the plug receptacle such that the locking hook is in a position away from the stop.

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 is incorporated herein by reference.

[0003] Modular automation platforms having a base module and a plurality of functional modules are known in the art. In order 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 automation 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 projection 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. The 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 flexible component disposed on the rigid component. The rigid component includes a frame extending around the second opening and at least one plug-in receptacle connected to the frame. The flexible component of the cap structure is positioned on the surface of the frame facing the functional housing connection surface and extends laterally around the second opening. A latching hook is positioned on one wall of the plug-in receptacle. The engaging element is inserted into the plug-in receptacle such that the flexible component abuts against the outer wall of the sealing socket and the latching hook engages within the recess.When the functional module is placed on the base module with the connection device open, the flexible component of the cap structure is positioned 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 engages with the first opening on the base housing connection surface such that the frame of the rigid component of the cap structure rests on the protrusion on the base housing connection surface, and the outer wall of the sealing socket is supported on the flexible component of the cap structure such that the functional housing connection surface is separated 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 is pressed radially 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 insert receptacle of the rigid component of the cap structure such that the locking hook of the insert receptacle is separated from the stop of the engaging element.

[0006] Advantageously, the flexible component, pressed in the region between the projection on the base housing connection surface and the sealing socket, embodies a radial seal or radial barrier against the ingress of dust, moisture, or chemicals. 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. When the frame of the cap structure is in contact with the projection on the base housing connection surface, and the functional module has not yet been pressed onto the base module using the connector, the flexible component is in an unpressed state. As a result, the functional housing connection surface is initially located away from the base housing connection surface. This means that the frictional force when mating the functional module is reduced, and the functional module can be mated with particularly little force. This means that the force required to mate onto the base module can be minimal, especially in the case of a large functional module with multiple radial seals. When the functional module is fitted, the locking hook of the plug-in receptacle abuts against the stop of the engaging element.

[0007] Only when the connector is closed is the flexible component pushed into place, resulting in the sealing effect of the radial seal. In this case, the cap structure is pushed into the base housing by the distance or stroke remaining between the functional housing connection surface and the base housing connection surface after the functional module has been fitted. This causes the locking hook to move away from the stop.

[0008] When the connector is released, the soft component presses against the functional module until it expands to a non-compressed state so that the stroke between the functional module and the base module returns to its original position. This facilitates the removal of the functional module. After the connector is released, the locking hook abuts against the stop again. When the functional module is removed, the cap structure is also removed together with it. Generally, this facilitates both the assembly and removal of the functional module onto the base module. In both cases, friction is reduced. This has the advantage of reducing wear on the radial seal.

[0009] In one embodiment, the functional housing connection surface includes at least one further engaging element positioned opposite the second opening and the engaging element. The wall of the further engaging element includes a further recess. Further edges of the wall of the further engaging element defining the further recess form 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 plug-in receptacle connected to the frame. A further locking hook is positioned on one wall of the further plug-in receptacle. The further engaging element is pushed into the further plug-in receptacle such that the flexible component abuts against the outer wall of the sealing socket and the further locking hook engages within the further recess. When the connection device is open and the functional module is placed on the base module, the flexible component of the cap structure positions the rigid component of the cap structure on the functional housing connection surface such that the further locking hook of the further plug-in receptacle abuts against the further stop of the further engaging element. When the connection device is closed, the further engaging element on the functional housing connection surface is pushed into the further plug-in receptacle of the rigid component of the cap structure such that the further locking hook of the further plug-in receptacle is separated from the further stop of the further engaging element.

[0010] Advantageously, if the functional housing connection surface includes at least the further engaging elements and the cap structure includes the further insert receptacle, the radial seal is pressed more evenly because the cap structure is inserted onto the engaging elements on opposite sides. The connection of at least two locking hooks to the functional housing connection surface allows the functional module to be removed evenly, because when the functional module is separated from the base module, the cap structure can be removed together with it on at least opposite sides of the second opening.

[0011] In one embodiment, the sealing socket is tapered 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 tapered region. Advantageously, the radial seal is pressed more effectively by the tapered sealing socket.

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

[0013] In one embodiment, an additional flexible component is positioned 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 connector is open, the additional flexible component is positioned on the base housing connection surface, and when the connector is closed, the additional flexible component is pressed toward the base housing connection surface. Advantageously, the additional flexible component forms an axial seal or axial barrier against the ingress of dust, moisture, or chemicals. 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 a further projection on the inner surface of the functional housing. When the functional module is placed on the base module, if the connector is open, the additional flexible component lies in contact with the further projection, and if the connector is closed, the additional flexible component is pressed toward the further projection. Advantageously, the additional flexible component forms an axial seal or axial barrier.

[0015] In one embodiment, the functional housing connection surface includes an additional projection projecting toward the side wall of the functional housing. The additional projection engages with the additional flexible component. When the functional module is placed on the base module with the connection device open, the additional flexible component lies in contact with the additional projection, and when the connection device is closed, it is pressed toward the additional projection. Advantageously, the additional projection forms both an axial seal or axial barrier and a radial seal or radial barrier. The axial barrier is formed in the region of the additional projection on the side of the functional housing connection surface facing the base housing connection surface. The radial barrier is formed on 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. A further flexible component is positioned in a groove formed on the functional housing connection surface. When the functional module is placed on the base module, the additional flexible component is positioned on the base housing connection surface when the connection device is open, and when the connection device is closed, the additional flexible component is pressed toward the base housing connection surface. Advantageously, the additional flexible component forms an axial seal or axial barrier.

[0017] A functional module for an automated 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 positioned 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 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 flexible component positioned on the rigid component. The rigid component includes a frame extending around the second opening and at least one plug-in receptacle connected to the frame. The flexible component of the cap structure is positioned on the surface of the frame facing the functional housing connection surface and extends laterally around the second opening. A locking hook is positioned on one wall of the plug-in receptacle. The engaging element is inserted into the plug-in receptacle such that the flexible component abuts against the outer wall of the sealing socket and the locking hook engages within the recess. The flexible component of the cap structure positions the rigid component of the cap structure on the functional housing connection surface such that the locking hook of the plug-in 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 cap structure engages within the first opening on the base housing connection surface, and the outer wall of the sealing socket is supported on the flexible component of the cap structure such that the frame of the rigid component of the cap structure rests on the projection on the base housing connection surface, and the functional housing connection surface is separated 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 so that the soft component of the cap structure is pressed radially 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 insert receptacle of the rigid component of the cap structure so that the locking hook of the insert receptacle is separated from the stop of the engaging element.

[0018] In one embodiment, the functional housing connection surface includes at least one further engaging element positioned opposite the second opening and the engaging element. The wall of the further engaging element includes a further recess. The 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 plug-in receptacle connected to the frame. A further locking hook is positioned on one wall of the further plug-in receptacle. The further engaging element is inserted into the further plug-in receptacle such that the flexible component abuts against the outer wall of the sealing socket and the further locking hook engages within the further recess. The flexible component of the cap structure positions the rigid component of the cap structure on the functional housing connection surface such that the further locking hook of the further plug-in receptacle abuts against the further stop of the further engaging element. When the connector is closed, the further engaging element on the functional housing connection surface is pushed into the further insert receptacle of the rigid component of the cap structure such that the further locking hook of the further insert receptacle is separated from the further stop of the further engaging element.

[0019] In one embodiment, the sealing socket is tapered at least partially 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 tapered portion.

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

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

[0022] In one embodiment, the side wall of the functional housing includes a further projection on the inner surface of the functional housing. When the functional module is placed on the base module, the additional flexible component abuts against the additional projection when the connector is open, and when the connector is closed, the additional flexible component is pressed toward the additional projection.

[0023] In one embodiment, the functional housing connection surface includes an additional projection that protrudes toward the side wall of the functional housing. The additional projection engages with the additional flexible component.

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

[0025] In a method for assembling an automated platform, the functional module is placed on the base module such that the frame of the rigid component of the cap structure rests on the projection on the base housing connection surface, the cap structure engages with the first opening on the base housing connection surface, and the outer wall of the sealing socket is supported on the flexible component of the cap structure so that the functional housing connection surface is separated from the base housing connection surface. The connector is closed, at which point the functional housing connection surface is pressed toward the base housing connection surface so that the flexible component of the cap structure is pressed radially in the region between the projection 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 insert receptacle of the rigid component of the cap structure so that the engaging element of the insert receptacle is separated from the stop of the engaging element.

[0026] In one embodiment, the connecting device is released. At this time, the flexible component presses against the outer wall of the sealing socket such that the functional housing connecting surface separates from the base housing connecting surface and the locking hook contacts 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 functional modules and a base module in a non-assembled state of the automation platform; Figure 8: Cross-sectional view of Figure 7 in a state where a functional module is attached onto a base module; Figure 9: Cross-sectional view of Figure 8 in a state where a functional module is pressed onto a 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 machinery. 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 exemplified and implemented as an industrial PC module. The industrial PC module is also called a higher-level module and is implemented to control the other functional modules 3.

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

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

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

[0034] The fourth functional module 10 of the control cabinet system 1 is exemplary embodied as an I / O module, which includes a connection unit 11 having input and output sections for analog and / or digital data. Field devices (e.g., actuators and / or sensors) can be controlled via the I / O module.

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

[0036] The connector 16 is implemented to connect the functional module 3 to the base module 2. In an exemplary embodiment of the automation platform 1, each connector 16 includes a plurality of screws for each functional module 3, and the functional module 3 is secured to the base housing connection surface 13 using these screws. The plurality of screws extend through the functional module 3. To accommodate the plurality of screws, each connector 16 on the base housing connection surface 13 includes, for example, a blind hole having threads. Alternatively, the connector 16 may be implemented in a different way. For example, the connector 16 may be implemented in the form of a locking structure, allowing the functional module 3 to be positioned on the base housing connection surface 13 by locking.

[0037] Figure 2 schematically shows a cross-sectional view of the automated platform 1 of Figure 1 along a plane stretched by the first direction 17 and the second direction 18, which extends along the functional module 3 and perpendicular to the base housing connection surface 13. A cross-section passing through the fourth functional module 10 is shown for illustrative purposes only. However, the following description applies appropriately to all functional modules 3. The same elements are given the same reference numerals as in Figure 1.

[0038] Base module 2 is intended to receive data from and transmit data to function module 3. For this purpose, base module 2 includes a base connection element 20 located within a base housing 12. Each function module 3 includes a function connection element 21 located within a function housing 14. In the assembled state of automation platform 1, one base connection element 20 and one function connection element 21 engage with each other, forming an interface between base module 2 and function module 3. Data can be exchanged between base module 2 and the fourth function module 10 through this interface. Voltage can be supplied to the fourth function module 10 by base module 2.

[0039] The base housing 12 includes a first opening 22 on the base housing connection surface 13. Each of the first openings 22 is located 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 Figure 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 positioned such that one is above the other. The functional connection element 21 is positioned within the area 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 can be used on the functional connection element 21.

[0041] The functional housing 14 may include any number of second openings 23 and functional connection elements 21 positioned within the area of ​​the second openings 23. For example, the second functional module 5 in Figure 1 extends over a total of six slots in 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 does not have second openings 23. On the other hand, two of the four second openings 23 do not have functional connection elements 21. In contrast, the first functional module 4 and the third functional module 8 each extend over, for example, four slots in the base module 2, and each of the first functional module 4 and the third functional module 8 includes two functional connection elements 21, which are positioned within the area of ​​one of the two first openings 23. The second opening 23, which does not have a functional connection element 21, 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 multiple slots or first openings 22 of the base module 2 and includes fewer 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 elements 20 may be omitted, and in some cases, the first openings 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 openings 22 when the base connection elements 20 are not provided, the first openings 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 elements 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 compressed radially by positive locking with the base housing 12. The functional housing connection surface 15 of the mounted functional module 3 may be separated from the plug 57, or it may be in contact with the plug 57 and optionally exert pressure on the plug 57 when mounted.

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

[0044] Figure 3 schematically shows a cross-sectional view of the automated platform 1 of Figure 1 along a plane stretched by the second direction 18 and the third direction 19, which extends perpendicularly to the base housing connection surface 13 and perpendicularly to the first direction 17. Cross-sections passing through the second function module 5, the third function module 8, and the fourth function module 10 are shown for illustrative purposes only. The same elements are given the same reference numerals as in Figures 1 and 2.

[0045] 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 functional housing 14, the functional housing connection surface 15 is rigidly 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 base 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 separate base plates 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 modified form of the functional housing 14 in which the functional housing connection surface 15 is rigidly connected to the side wall 25, each functional housing 14 includes a cap 27. The cap 27 allows access to the internal area of ​​the functional housing 14. For example, by opening the cap 27, components within the functional housing 14 can be positioned or replaced. While merely illustrative, the functional housings 14 of the second functional module 5 and the third functional module 8 are implemented such that 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 a certain angle along the diagonal of the opposing faces of the functional housing 14. This can also be seen in Figure 1. In a modified form having a separate bottom plate 26, the bottom plate 26 can be removed, making the functional housing 14 accessible.

[0047] The automated platform 1 is based on the idea of ​​an improved sealing concept, which will be described in more detail below. The automated platform 1 needs to be protected from the ingress of, for example, dust, moisture, and chemicals. For this purpose, the automated system 1 includes a radial seal 28 positioned between the functional module 3 and the base module 2. The radial seal 28 is similarly implemented for each type of functional module 4, 5, 8, and 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, the first flexible component 31 is positioned 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 connector 16 is open, the first flexible component 31 is positioned on the base housing connection surface 13. When the connector 16 is closed, the first flexible component 31 is pressed toward the base housing connection surface 13, forming a first axial barrier between the base housing connection surface 13 and the functional housing connection surface 15 against dust, moisture, or chemicals.

[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 applies appropriately to all functional modules 3 having the first axial seal 29. Figure 4 further shows an enlarged view of a portion 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 flexible component 31, positioned within the groove 32, is embodied exemplary as an O-ring. Alternatively, the first flexible component 31 may be positioned within the groove 32 using a molding process, for example, an injection molding process. The groove 32 and the first flexible component 31 surround the second opening 23 in the functional housing connection surface 15 from the side. Similarly, the groove 32 and the first flexible component 31 surround all functional connection elements 21 and all radial seals 28 from the side.

[0051] The first axial seal 29 includes retaining nubs (small protrusions) 33 for improving the fixation of the first soft component 31 within the groove 32. The retaining nubs 33 are formed by the first soft component 31. Although the retaining nubs 33 are exemplary arranged alternately on opposing faces of the first soft component 31, the retaining nubs 33 may be arranged differently. However, the retaining nubs 33 may be omitted.

[0052] Figure 5 schematically shows a perspective view of the fourth functional module 10. Here, the fourth functional module 10 is shown in both its assembled and unassembled states. Figure 5 shows only the fourth functional module 10 as an example to illustrate the radial seal 28 of the automation platform 1. For this reason, the following description applies to all of the radial seals 28 for the functional module 3 and the base module 2. Identical elements are identified using the same reference numbers as in the previously described drawings.

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

[0054] The shape of the engaging elements 34 and 36 is, for example, cylindrical. The engaging elements 34 and 36 open on a surface facing away from the functional housing connection surface 15, so that the functional housing 14 is accessible. This allows cooling air to be exchanged between the inside of the base housing 14 and the inside of the functional housing 14. For this reason, the engaging elements 34 and 36 may also be called ventilation nozzles. However, the engaging elements 34 and 36 do not necessarily have to be configured to open and embody as ventilation nozzles. The engaging elements 34 and 36 may have different shapes. The important thing is that the engaging elements 34 and 36 protrude 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 on 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, in the region of the engaging elements 34, 36, is formed by 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, nor is it partially formed by the engaging elements 34, 36.

[0056] The functional module 3 further includes a cap structure 37, which comprises a rigid component 38 and a second flexible 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 insertable receptacle 41 connected to the frame 40. The second flexible 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. A radial seal 28 is formed by the second flexible component 39.

[0057] The second flexible component 39 may be placed on the rigid component 38 using a molding process (for example, injection molding). In this case, the rigid component 38 and the second flexible component 39 are joined to each other. However, the second flexible component 39 may alternatively be embodied as an O-ring. Nevertheless, a material-locking connection between the rigid component 38 and the second flexible component 39 has the advantage that the second flexible component 39 does not need to be placed on the rigid component 38 when assembling the functional module 3 or the automation platform 1.

[0058] Furthermore, multiple plug-in receptacles 41 may be provided. It is advantageous that the number of plug-in receptacles 41 in the cap structure 37 be the same as the number of engaging elements 34, 36 on the functional housing connection surface 15. For this reason, the cap structure 37 in the exemplary embodiment shown in Figure 5 includes a further plug-in receptacle 42. The further plug-in receptacle 42 is connected to the frame 40 and is located on the side of the frame 40 opposite to the plug-in receptacle 41. The plug-in receptacles 41, 42 are embodied so as to open on a surface facing away from the frame 40. As a result, the plug-in receptacles 41, 42 and the engaging elements 34, 36 can each be used as ventilation nozzles. However, this is not absolutely necessary.

[0059] When assembling the functional module 3, the functional housing connection surface 15 is positioned 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 is guided through the first opening 22 in the base housing connection surface 13 and can be connected to the base connection element 20. When assembling the functional module 3, the plug-in receptacles 41 and 42 are inserted onto the functional housing connection surface 15 such that the engaging elements 34 and 36 are pushed into and engage with the plug-in receptacles 41 and 42, respectively. For this reason, the plug-in receptacles 41 and 42 have a similar geometric shape to the engaging elements 34 and 36. Locking hooks 43 and 44 are located on one wall of each plug-in receptacle 41 and 42. The locking hook 43 of the plug-in receptacle 41 and the further locking hook 44 of the further plug-in receptacle 44 are positioned on opposite surfaces of the plug-in receptacles 41 and 42.

[0060] The recesses 45 and 46 are located on one wall of each engaging element 34 and 36. The recess 45 of the engaging element 34 and the further recess 46 of the further engaging element 36 are located on the mutually opposing surfaces of the engaging elements 34 and 36. When only one engaging element 34 is provided and correspondingly only one plug-in receptacle 41 is provided, the recess 45 and the locking hook 43 are located on the surface of the engaging element 34 or plug-in receptacle 41 facing the second opening 23, respectively. The engaging elements 34 and 36 are inserted into the plug-in receptacles 41 and 42 such that the second flexible component 39 abuts against the outer wall of the sealing socket 35 and the locking hooks 43 and 44 of the plug-in receptacles 41 and 42 engage in the recesses 45 and 46 of the engaging elements 34 and 36, respectively.

[0061] In each case, recesses 45, 46 are defined by the edges of the walls of the engaging elements. In each case, these edges form stops 47, 48 on the side of the recesses 45, 16 that faces 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 hard component 38 of the cap structure 38 is positioned on the functional housing connection surface 15 by the second soft component 39 of the cap structure 37, such that the locking hooks 43 and 44 of the insertion receptacles 41 and 42 abut against the stops 47 and 18 of the engaging elements 34 and 36, respectively. The locking hook 43 abuts against the stop 47. The other locking hook 44 abuts against the other stop 48.

[0063] Figure 6 shows a schematic cross-sectional view of the automation platform 1 shown in Figure 3, except that only the fourth function module 10 and the base module 2 are shown. The fourth function module 10 is shown in more detail in Figure 6 than in Figure 3. In Figure 6, only the fourth function module 10 is shown as an example to illustrate in more detail 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 for each of the other function modules 10, positioned between the base module 2 and the function module 3. Figure 6 also shows an enlarged view of the area of ​​the radial seal 28. The same elements are given the same reference numerals as in the drawings described earlier.

[0064] On the base housing connection surface 13, a projection 49 is formed around the first opening 22. The projection 49 is positioned on the surface of the base housing connection surface 13 facing the interior of the base housing 12. The projection 49 may also be referred to as a seat. When the functional module 3 is placed on the base module 2 with the connection device 16 open, the cap structure 37 engages with the first opening 22 on the base housing connection surface 13 so that the frame 40 of the rigid component 38 of the cap structure 37 rests on the projection 49 on 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 37 so that the functional housing connection surface 15 is separated from the base housing connection surface 13. This is not shown in Figure 6, because in this case the automated platform 1 is shown in an assembled state with the connection device 16 closed. When the functional module 3 is attached to the base module 2 and the connection device 16 is open, the distance between the base housing connection surface 13 and the functional housing connection surface 15 may 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 automated platform 1 shown in Figures 7 to 9. When the slot is sealed by the plug 57, the projection 49 may act as a stop or depth limiter for the plug 57.

[0065] As shown in Figure 6, when the connector 16 is closed, the functional housing connection surface 15 is pressed toward the base housing connection surface 13 such that the second soft component 39 of the cap structure 37 is pressed radially in the area between the projection 49 on the base housing connection surface 13 and the outer wall of the sealing socket 35, and the engaging elements 34 and 36 of the functional housing connection surface 15 are inserted into the insert receptacles 41 and 42 of the hard component 38 of the cap structure 37 such that the locking hooks 43 and 44 of the insert receptacles 41 and 42 are separated from the stops 47 and 48 of the engaging elements 34 and 36, respectively.

[0066] The second flexible component 39 lies 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 Figure 6, the sealing socket 35 may be embodied so as to taper at least partially from the functional housing connection surface 15. The second flexible component 39 of the cap structure 37 lies in contact with the outer wall of the sealing socket 35 in the area of ​​the tapered portion. This causes the second flexible component 39 to be pressed more effectively. Furthermore, the second flexible component 39, above the projection 39, abuts against the wall defining the first opening 22 in the base housing connection surface 13. This forms a second radial barrier. Figure 6 shows the second seal 28 in both compressed and uncompressed states to illustrate the sealing effect. In Figure 6, the portion of the second flexible component 39 overlapping with the sealing socket 35 shows one geometric shape of the second flexible component 39 in the uncompressed state. In the compressed state, the second flexible component 39 extends only as far as 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 flexible component 50 is positioned between the functional housing connection surface 15 and the side wall 25 of the functional housing 14. For example, the third flexible component 50 may be positioned on the edge 51 of the functional housing connection surface 15 using a molding process (e.g., using an injection molding process). Alternatively, the third flexible 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 connector 16 open, the third flexible component 50 is positioned on the base housing connection surface 13, and when the connector 16 is closed, it is pressed toward the base housing connection surface 13. This forms a second axial barrier against dust, moisture, or chemicals. Furthermore, the third flexible component 50 lies in contact with the side wall 25 of the functional housing 14. This forms a third radial barrier.

[0069] According to an exemplary embodiment of the fourth functional module 10, the side wall 25 of the functional housing 14 includes a further projection 52 on the inner surface of the functional housing 14. For example, a groove-like recess 53 is formed between the further projection 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 connector 16 open, the third flexible component 50 abuts against the further projection 52. When the connector 16 is closed, the third flexible component 50 is pressed toward the further projection 52. This forms a third axial barrier. However, the further projection 52 is not necessarily required and may be omitted. In Figure 6, the third flexible component 50 is also shown in both compressed and uncompressed states to illustrate the sealing effect. In Figure 6, the portion of the third flexible component 50 overlapping with the projection 52 is shown in the uncompressed state.

[0070] The functional housing connection surface 15 further includes an additional projection 54 that protrudes toward the side wall 25 of the functional housing 14. The additional projection 54 fits into (embeds into) the third flexible component 50. When the fourth functional module 10 is placed on the base module 2 with the connection device 16 open, the third flexible component 50 abuts against the additional projection 54. When the connection device 16 is closed, the third flexible component 50 is pressed toward the additional projection 54. This forms a fourth axial barrier and a fifth axial barrier. 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. Furthermore, the third radial barrier is formed in the region where the third flexible component 50 is pressed toward 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 process for assembling the automated platform 1. In each case, Figures 7 to 9 correspond to the cross-sectional view in Figure 2. The fourth functional module 10 is shown merely as an example to illustrate the effect of the radial seal 28 during assembly.

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

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

[0074] In this case as well, the hard component 38 of the cap structure 37 is positioned on the functional housing connection surface 15 by the second soft component 39 of the cap structure 37 so that the locking hooks 43 and 44 of the insertion receptacles 41 and 42 abut against the stops 47 and 48 of the engaging elements 34 and 36, respectively. This is because the second soft component 39 has not yet been pressed down since the connection device 16 is open.

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

[0076] Figure 8 also shows a magnified view of the area of ​​the locking hook 43 that contacts the stop 47. This magnified 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 yet being pressed in this state.

[0077] As a result, the second flexible component 39 remains unpressed during the insertion or positioning of the functional module 3. Consequently, the functional module 3 can be positioned virtually frictionally and therefore without the application of force.

[0078] Figure 9 is chronologically subsequent to Figure 8, showing the state after the connector 16 has been closed and the functional module 3 has been connected to the base module 2. Similar to Figure 6, Figure 9 also shows the second seal 28 in both compressed and uncompressed states. Therefore, Figure 9 also shows the portion of the second flexible component 39 that overlaps with the sealing socket 35, and this portion shows the geometric shape of the second flexible component 39 in the uncompressed state.

[0079] By closing the connector 16, the functional housing connection surface 15 is pressed toward the base housing connection surface 13 such that the second soft component 39 of the cap structure 37 is pressed radially in the region between the projection 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 insert receptacles 41, 42 of the rigid component 38 of the cap structure 37 such that the locking hooks 43, 44 of the insert receptacles 41, 42 are separated from the stops 47, 48 of the engaging elements 34, 36, respectively. Figure 9 shows an enlarged view of the region at a distance 56 from one of the multiple locking hooks 44 and the associated stop 48. Thus, the functional module 3 is simply pulled to its terminal position by the connector 16, and the functional housing connection surface 15 comes into contact with the base housing connection surface 13. Only then does the radial seal 28 create a sealing effect. This allows the functional module 3 to be fitted with minimal effort. This simplifies the insertion or installation of particularly large functional modules 3 having multiple functional connection elements 21 and radial seals 28. In addition, it reduces wear on the radial seals 28 during assembly.

[0080] When the connector 16 is opened or released again, the second flexible component 39 presses against the outer wall of the sealing socket 35 so that the functional housing connection surface 15 separates from the base housing connection surface 13 and the locking hooks 43, 44 contact the stops 47, 48 of the engaging elements 34, 36. When the pressure on the second flexible component generated by the connector 16 is released, the functional housing 14 is pressed by the second flexible component 39 and becomes detached, and there is no longer significant friction between the functional module 3 and the base module 2. When the connector 16 is released, the second flexible component 39 is already pressing against the functional module 3 with a force component, as a result supporting the release of the functional module, which can be done with little 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 removed more easily from the base module 2 by stroke 55. Because the locking hooks 43 and 44 are initially separated from the stops 47 and 48, the cap structure 37 initially remains in place, but the functional module 3 may already be pulled away in accordance with the stroke 55.
