Description

[0001] manual

[0002] The invention relates to an automation platform.

[0003] This patent application claims priority from German patent application DE 10 2022 113 306.0 filed on May 25, 2022, the disclosure of which is incorporated herein by reference.

[0004] Modular automation platforms with a base module and a plurality of functional modules are known from the prior art. In order to protect the automation platform from moisture and / or dust, seals are used between the functional modules and the base module.

[0005] An object of the invention is to provide an improved automation platform and an improved functional module for an automation platform, and to specify an improved method for assembling an automation platform. These objects are achieved by an automation platform, a functional module for an automation platform and a method for assembling an automation platform, which have the features of the respective independent claims. Advantageous improvements are specified in the dependent claims.

[0006] An automation platform comprises a base module, at least one functional module and at least one connection device for connecting the base module and the functional module. The base module comprises a base housing having a base housing connection surface. The base housing connection surface has at least one first opening. A protrusion extending around the first opening is formed in the base housing connection surface. The functional module comprises a functional housing having a functional housing connection surface. The functional housing connection surface has at least one second opening, at least one engaging element arranged at the second opening and a sealing interface extending around the second opening. The wall of the engaging element has a recess. The edge of the wall of the engaging element forms a stopper on the side of the recess facing away from the functional housing connection surface. The functional module comprises a cover structure having a hard component and a soft component arranged on the hard component. The hard component has a frame extending around the second opening and at least one insertion socket connected to the frame. The soft component of the cover structure is arranged on the side of the frame facing the functional housing connection surface and laterally surrounds the second opening. A locking hook is arranged on the wall of the insertion socket. The engaging element is inserted into the insertion socket in such a way that the soft component abuts against the outer wall of the sealing interface and the locking hook engages in the recess. When the functional module is mounted on the base module, with the connection device open, the soft part of the cover structure arranges the hard part of the cover structure on the functional housing connection surface so that the locking hook inserted into the socket abuts the stopper of the engagement element, and the cover structure engages into the first opening in the base housing connection surface in such a way that the frame of the hard part of the cover structure rests on the protrusion in the base housing connection surface, and the outer wall of the sealing interface is supported on the soft part of the cover structure so that the functional housing connection surface is spaced apart from the base housing connection surface. With the connection device closed, the functional housing connection surface is pressed against the base housing connection surface in such a way that the soft part of the cover structure is radially pressed in the area between the protrusion in the base housing connection surface and the outer wall of the sealing interface, and the engagement element of the functional housing connection surface is inserted into the insertion socket of the hard part of the cover structure in such a way that the locking hook inserted into the socket is spaced apart from the stopper of the engagement element.

[0007] The soft component pressed in the area between the protrusion in the base housing connection surface and the sealing interface advantageously forms a radial seal or a radial barrier to prevent the penetration of dust, moisture or chemicals. One advantage of the radial seal is that the radial seal is not initially pressed when the functional module is installed on the base module. If the frame of the cover structure abuts against the protrusion in the base housing connection surface and if the functional module is not yet pressed on the base module by the connecting device, the soft component is in an unpressed state. As a result, the functional housing connection surface is initially at a distance from the base housing connection surface. Therefore, the installation of the functional module can be achieved with particularly small force consumption because the friction force is reduced when the functional module is installed. As a result, large functional modules with multiple radial seals in particular can be installed on the base module with very little force consumption. In the installed state of the functional module, the locking hook inserted into the socket abuts the stopper of the engaging element.

[0008] Only when the connection is closed is the soft part pressed, thereby achieving the sealing effect of the radial seal. In this case, after the functional module is installed, the cover structure is pushed into the base housing through the remaining distance or stroke between the functional housing connection surface and the base housing connection surface. This distance or stroke is maintained between the functional housing connection surface and the base housing connection surface after the functional module is installed. As a result, the locking hook is spaced apart from the stop.

[0009] When the connection device is released, the soft component presses on the functional module until the soft component has expanded to its unpressed shape, thereby restoring the travel between the functional module and the base module. This facilitates the removal of the functional module. After the connection device is released, the latching hook abuts the stop again, as a result of which the cover structure is entrained when the functional module is removed. Overall, therefore, both the assembly and disassembly of the functional module on the base module are simplified. In both cases, the friction forces are reduced, thereby advantageously reducing the wear of the radial seal.

[0010] In one embodiment, the functional housing connection surface has at least one other engagement element arranged in the second opening and opposite to the engagement element. The wall of the other engagement element has another recess. The other edge of the wall of the other engagement element that limits the other recess forms another stopper on the side of the other recess facing away from the functional housing connection surface. The hard component has at least one other insertion socket connected to the frame. The other locking hook is arranged on the wall of the other insertion socket. The other engagement element is inserted into the other insertion socket in such a way that the soft component abuts against the outer wall of the sealing interface and the other locking hook engages in the other recess. When the functional module is mounted on the base module, when the connection device is opened, the soft component of the cover structure arranges the hard component of the cover structure on the functional housing connection surface so that the other locking hook of the other insertion socket abuts the other stopper of the other engagement element. When the connection device is closed, the other engagement element of the functional housing connection surface is inserted into the other insertion socket of the hard component of the cover structure in such a way that the other locking hook of the other insertion socket is spaced apart from the other stopper of the other engagement element.

[0011] Advantageously, when the functional housing connection surface has at least one further engagement element and the cover structure has one further insertion socket, the radial seal is pressed more evenly, since the cover structure is inserted onto the engagement element on its opposite sides. Since at least two latching hooks are connected to the functional housing connection surface, an even removal of the functional module can be allowed, since the cover structure can be entrained on at least two opposite sides of the second opening when the functional module is separated from the base module.

[0012] In one embodiment, the sealing interface tapers at least in sections from the functional housing connection surface. The soft part of the cover structure bears against the outer wall of the sealing interface in the region of the conical portion. Advantageously, the radial seal is pressed more effectively by the conical sealing interface.

[0013] In one embodiment, the sealing interface is connected to the joining element and is formed thereby in the region of the joining element or laterally surrounds the joining element.

[0014] In one embodiment, the additional soft component is arranged between the functional housing connection surface and the side wall of the functional housing. When the functional module is mounted on the base module, the additional soft component is arranged on the base housing connection surface when the connection device is open and is pressed against the base housing connection surface when the connection device is closed. The additional soft component advantageously forms an axial seal or axial barrier against the penetration of dust, moisture or chemicals. In addition, a radial barrier is formed in the area between the side wall of the functional housing and the functional housing connection surface.

[0015] In one embodiment, the side wall of the functional housing has a further protrusion on the inner side of the functional housing. When the functional module is mounted on the base module, the additional soft component rests on the further protrusion when the connection device is open and presses against the further protrusion when the connection device is closed. The additional soft component advantageously forms an axial seal or axial barrier.

[0016] In one embodiment, the functional housing connection surface has an additional protrusion protruding in the direction of the side wall of the functional housing. The additional protrusion is embedded in the additional soft component. When the functional module is mounted on the base module, the additional soft component rests on the additional protrusion when the connection device is open and presses against the additional protrusion when the connection device is closed. The additional protrusion advantageously forms an axial seal or axial barrier and a radial seal or radial barrier. The axial barrier is formed on the side of the functional housing connection surface facing the base housing connection surface and in the area of ​​the additional protrusion. The radial barrier is formed on the edge of the functional housing connection surface.

[0017] In one embodiment, the functional housing connection surface is rigidly connected to the side wall of the functional housing. The other soft component is arranged in a groove formed on the functional housing connection surface. When the functional module is mounted on the base module, the other soft component is arranged on the base housing connection surface when the connection device is open and is pressed against the base housing connection surface when the connection device is closed. The other soft component advantageously forms an axial seal or an axial barrier.

[0018] A functional module for an automation platform comprises a functional housing having a functional housing connection surface. The functional housing connection surface has at least one second opening, at least one engaging element arranged at the second opening, and a sealing interface extending around the second opening. The wall of the engaging element has a recess. The edge of the wall of the engaging element forms a stopper on the side of the recess facing away from the functional housing connection surface. The functional module comprises a cover structure having a hard component and a soft component arranged on the hard component. The hard component has a frame extending around the second opening and at least one insertion socket connected to the frame. The soft component of the cover structure is arranged on the side of the frame facing the functional housing connection surface and laterally surrounds the second opening. A locking hook is arranged on the wall of the insertion socket. The engaging element is inserted into the insertion socket in such a way that the soft component abuts against the outer wall of the sealing interface and the locking hook engages in the recess. The soft component of the cover structure arranges the hard component of the cover structure on the functional housing connection surface so that the locking hook of the insertion socket abuts against the stopper of the engaging element. The functional module can be mounted on the base module in such a way that, with the connection device open, the cover structure engages in the first opening in the base shell connection surface in such a way that the frame of the hard part of the cover structure rests on the protrusion in the base shell connection surface and the outer wall of the sealing interface is supported on the soft part of the cover structure, so that the functional shell connection surface is spaced apart from the base shell connection surface. With the connection device closed, the functional shell connection surface is pressed against the base shell connection surface in such a way that the soft part of the cover structure is radially pressed in the area between the protrusion in the base shell connection surface and the outer wall of the sealing interface, and the engagement element of the functional shell connection surface is inserted into the insertion socket of the hard part of the cover structure in such a way that the locking hook of the insertion socket is spaced apart from the stop of the engagement element.

[0019] In one embodiment, the functional housing connection surface has at least one other engagement element arranged in the second opening and opposite to the engagement element. The wall of the other engagement element has another recess. The other edge of the wall of the other engagement element that limits the other recess forms another stopper on the side of the other recess facing away from the functional housing connection surface. The hard component has at least one other insertion socket connected to the frame. The other locking hook is arranged on the wall of the other insertion socket. The other engagement element is inserted into the other insertion socket in such a way that the soft component abuts against the outer wall of the sealing interface and the other locking hook engages in the other recess. The soft component of the cover structure arranges the hard component of the cover structure on the functional housing connection surface so that the other locking hook of the other insertion socket abuts against the other stopper of the other engagement element. When the connecting device is closed, the other engagement element of the functional housing connection surface is inserted into the other insertion socket of the hard component of the cover structure in such a way that the other locking hook of the other insertion socket is spaced apart from the other stopper of the other engagement element.

[0020] In one embodiment, the sealing interface tapers at least in sections from the functional housing connection surface. The soft part of the cover structure bears against the outer wall of the sealing interface in the region of the conical section.

[0021] In one embodiment, the sealing interface is connected to the joining element and is formed thereby in the region of the joining element or laterally surrounds the joining element.

[0022] In one embodiment, the additional soft component is arranged between the functional housing connection surface and the side wall of the functional housing. When the functional module is mounted on the base module, the additional soft component is arranged on the base housing connection surface when the connection device is open, and is pressed against the base housing connection surface when the connection device is closed.

[0023] In one embodiment, the side wall of the functional housing has another protrusion on the inner side of the functional housing. When the functional module is mounted on the base module, the additional soft component abuts against the other protrusion when the connection device is open, and presses against the other protrusion when the connection device is closed.

[0024] In one embodiment, the functional housing connection surface has an additional protrusion protruding in the direction of the side wall of the functional housing. The additional protrusion is embedded in the additional soft component.

[0025] In one embodiment, the functional housing connection surface is rigidly connected to the side wall of the functional housing. The other soft component is arranged in a groove formed on the functional housing connection surface. When the functional module is mounted on the base module, the other soft component is arranged on the base housing connection surface when the connection device is open, and is pressed against the base housing connection surface when the connection device is closed.

[0026] In a method for assembling an automation platform, a functional module is mounted on a base module in such a way that a cover structure engages in a first opening in a base housing connection surface in such a way that a frame of a hard part of the cover structure rests on a protrusion in the base housing connection surface and an outer wall of a sealing interface is supported on a soft part of the cover structure in such a way that the functional housing connection surface is spaced apart from the base housing connection surface. A connection device is closed, whereby the functional housing connection surface is pressed against the base housing connection surface in such a way that the soft part of the cover structure is radially pressed in the area between the protrusion in the base housing connection surface and the outer wall of the sealing interface and an engagement element of the functional housing connection surface is inserted into an insertion socket of the hard part of the cover structure in such a way that a locking hook of the insertion socket is spaced apart from a stop of the engagement element.

[0027] In one embodiment, the connection device is released, whereby the soft component is pressed against the outer wall of the sealing interface, so that the functional housing connection surface is spaced apart from the base housing connection surface and the latching hook abuts against a stop of the engagement element.

[0028] The automation platform and the method for assembling the automation platform are explained in detail below with reference to the schematic diagram. In the accompanying drawings:

[0037] Fig. 9 Shows Figure 8 A cross-sectional view of a functional module pressed against a base module.

[0038] Figure 1 An exemplary automation platform 1 is schematically shown in a perspective view. The automation platform 1 comprises electrical and / or electronic components and serves as a distribution system for field devices, such as sensors and actuators. The automation platform 1 can be used, for example, in a production machine. The automation platform 1 can replace a switch cabinet.

[0039] The automation platform 1 is modular. The automation platform 1 has a base module 2 and functional modules 3. As an example, the automation platform 1 has a total of four functional modules 3. The automation platform 1 can also have a different number of functional modules 3, but the automation platform 1 has at least one functional module 3. Merely as an example, the functional modules 3 have different sizes.

[0040] The first functional module 4 is designed as an industrial PC module as an example. An industrial PC module can also be referred to as a higher-level module and is designed to control the remaining functional modules 3 .

[0041] As an example, the second functional module 5 is constructed as a system module. The system module has a terminal 6 for feeding a system voltage, a fuse ( Figure 1 ) and a main switch 7 for switching the system voltage.

[0042] As an example, the third functional module 8 is configured as a bus coupler. As an example, the bus coupler has two terminals 9, each of which has a data input terminal and a data output terminal. Data communication can be based on, for example, Ethernet or EtherCAT protocols. However, data communication is not limited to the above protocols. In addition to the data input terminal and the data output terminal, each terminal 9 of the bus coupler can have a voltage input terminal and a voltage output terminal for coupling and transferring voltage. In this case, data communication and voltage can be fed through the common terminal 9, but this is not necessary. On the contrary, a separate voltage terminal can be provided to feed in and transfer voltage.

[0043] Optionally, the third functional module 8 can also be configured as a relay module for directly switching voltage. The relay module can be used, for example, to supply power to fans, electric heaters, lighting, and motors (e.g., three-phase asynchronous motors). Optionally, the third functional module 8 can also be configured as a servo amplifier or a frequency converter.

[0044] The fourth functional module 10 of the switch cabinet system 1 is designed as an I / O module by way of example and comprises a terminal 11 with analog and / or digital data inputs and outputs. Field devices, such as actuators and / or sensors, can be controlled via the I / O module.

[0045] The base module 2 comprises a base housing 12 with a base housing connection surface 13. Each functional module 3 comprises a functional housing 14 with a functional housing connection surface 15. In the assembled state of the automation platform 1, the functional modules 3 are each arranged with their functional housing connection surface 15 on the base housing connection surface 13 and are pressed against the base housing connection surface 13 by means of a connection device 16 in each case.

[0046] The connection device 16 is configured to connect the functional module 3 to the base module 2. In an exemplary embodiment of the automation platform 1, each connection device 16 comprises a plurality of screws per functional module 3, by means of which the functional module 3 is fixed to the base housing connection surface 13. The screws extend through the functional module 3. In order to accommodate the screws, the connection device 16 has, for example, blind holes on the base housing connection surface 13, each of which has a thread. The connection device 16 can also be configured in different ways. For example, the connection device 16 can be in the form of a latching structure, whereby the functional module 3 can be arranged on the base housing connection surface 13 in a latching manner.

[0047] Figure 2 Schematically shows Figure 1 1 is a cross-sectional view of an automation platform 1 along a plane spanned by a first direction 17 and a second direction 18 and extending along the functional modules 3 and perpendicular to the base housing connection surface 13. Only a cross-section through the fourth functional module 10 is shown as an example. However, the following description applies accordingly to all functional modules 3. The same elements are represented by Figure 1 The same reference numerals are used in the drawings.

[0048] The base module 2 serves to receive data from the functional module 3 and to send data to the functional module 3. For this purpose, the base module 2 has a base connection element 20 arranged in the base housing 12. Each functional module 3 has a functional connection element 21 arranged in the functional housing 14. In the assembled state of the automation platform 1, each base connection element 20 and the functional connection element 21 engage with each other and form an interface between the base module 2 and the functional module 3 in each case. Via the interface, data can be exchanged between the base module 2 and the fourth functional module 10. Voltage can also be supplied from the base module 2 to the fourth functional module 10.

[0049] The base housing 12 has a first opening 22 at the base housing connection surface 13. The first opening 22 is arranged in the region 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 configured as a built-in plug or a built-in socket. As an example, Figure 2 The base connection element 20 is configured as a built-in socket. The plurality of contact openings of the base connection element 20 can be arbitrary.

[0050] The functional housing 14 of the fourth functional module 10 has a second opening 23 at its functional housing connection surface 15. In the assembled state of the automation platform 1, when the functional housing connection surface 15 of the functional housing 14 abuts against the base housing connection surface 13 of the base housing 12, the first opening 22 and the second opening 23 are arranged on top of each other. The functional connection element 21 is arranged in the region of the second opening 23 and protrudes from the functional housing 14. The functional connection element 21 can be configured as a built-in plug or a built-in socket. As an example, the functional connection element 21 of the fourth functional module 10 is configured as a built-in plug. The plurality of contact pins of the functional connection element 21 can be any number.

[0051] The functional housing 14 can have any number of second openings 23 and functional connection elements 21 respectively arranged in the region of the second openings 23. For example, Figure 1 The second functional module 5 extends onto a total of six slots of the base module 2. Furthermore, as an example, the second functional module 5 has 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. However, for two of the four second openings 23, no functional connection element 21 is provided. On the other hand, the first functional module 4 and the third functional module 8 extend onto four slots of the base module 2, respectively, and have two functional connection elements 21 in each case, each of which is arranged in the region of one of the two first openings 23. The second opening 23 in which no functional connection element 21 is provided can be used for ventilation of the second functional module 5 or any functional module 3, and can also be used for guiding the functional module 3 during assembly.

[0052] If the functional module 3 extends over a plurality of slots or first openings 22 of the base module 2, but has a smaller number of second openings 23 and / or functional connection elements 21, the slots of the base module can be omitted, i.e. at least the base connection element 20 can be omitted, and if necessary, the first opening 22 can also be omitted. For example, in the case of the second functional module 5, a total of four slots of the base module 2 can be omitted. If no base connection element 20 is provided, the first opening 22 can also be sealed with a plug 57 instead of omitting the first opening 22. Such a plug 57 can be made of a solid material, for example, having a circumferential groove and an O-ring seal arranged in the circumferential groove. The plug 57 can also surround the base connection element 20 of the slot. Before assembling the functional module 3, the plug 57 can be inserted into an unused slot of the base module 2 in order to seal it. In this case, the O-ring seal is radially compressed by a shape fit with the base housing 12. The functional housing connection surface 15 of the assembled functional module 3 can be spaced apart from the plug 57, or rest on the plug 57, and optionally exert pressure on the plug 57 in the assembled state.

[0053] In order to exchange data with the functional module 3, the base module 2 can have a connection unit in the base housing 12 which can be connected to each other via a data bus. Figure 1 and Figure 2 The connection units not shown in the figure can be configured, for example, as application specific integrated circuits (ASICs). For example, the connection units can be components of a circuit board (also not shown) of the base module 2. In order to communicate with the functional modules 3, each connection unit is connected to a base connection element 20. The functional connection elements 21 of the functional modules 3 are in turn connected to components arranged in the functional housing 14. This can be, for example, a circuit board 24.

[0054] Figure 3 Schematically shows Figure 1 1 is a cross-sectional view of the automation platform 1 along a plane spanned by the second direction 18 and the third direction 19 and extending perpendicularly to the base housing connection surface 13 and perpendicularly to the first direction 17. The cross-section through the second functional module 5, the third functional module 8 and the fourth functional module 10 is shown only as an example. The same elements are represented by Figure 1 and Figure 2 The same reference numerals are used in the drawings.

[0055] The functional modules 3 have different types of functional housings 14. The second functional module 5 and the third functional module 8 each have a functional housing 14, wherein the functional housing connection surface 15 is rigidly connected to the side wall 25 of the functional housing 14. This also applies to Figure 1 4. 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 configured as a separate base plate 26. In contrast, the first functional module 4, the second functional module 5 and the third functional module 8 can also each have a separate base plate 26, and in the case of the fourth functional module 10, the functional housing connection surface 15 is rigidly connected to the side wall 26 of the functional housing 14.

[0056] In a variant of the functional housing 14 with the respective functional housing connection surface 15 rigidly connected to the side wall 25, each functional housing 14 has a cover 27. The cover 27 allows access to areas inside the functional housing 14 in order to arrange or replace components in the functional housing 14, for example by opening the cover 27. Merely by way of example, the functional housings 14 of the second functional module 5 and the third functional module 8 are constructed such that the side walls 25 and the parts of the cover 27 rigidly connected to the functional housing connection surface 15 can in each case be separated from each other obliquely and essentially along opposite side diagonals of the functional housing 14, which can also be Figure 1In the variant with a separate bottom plate 26 , the functional housing 14 is accessible because the bottom plate 26 can be removed.

[0057] The automation platform 1 is based on the idea of ​​an improved sealing concept, which will be explained in more detail below. For example, the automation platform 1 must be protected from the penetration of dust, moisture or chemicals. For this purpose, the automation system 1 has in each case a radial seal 28 arranged between the functional module 3 and the base module 2. The radial seal 28 is constructed identically for each type of functional module 4, 5, 8, 10.

[0058] The automation platform 1 also has a first axial seal 29 and a second axial seal 30. The first, second and third functional modules 4, 5, 8 each have a functional housing connection surface 15 rigidly connected to the side wall 25 of the functional housing 14. In these cases, in each case, a first soft component 31 is arranged in a groove 32 formed on the functional housing connection surface 15. When the first, second and third functional modules 4, 5, 6 are mounted 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 pressed against the base housing connection surface 13 respectively and forms a first axial barrier against dust, moisture or chemicals between the base housing connection surface 13 and the functional housing connection surface 15.

[0059] Figure 4 Schematically, a perspective view of a third functional module 8 is shown. The third functional module 8 is shown here only by way of example. However, the following description applies accordingly to all functional modules 3 having a first axial seal 29. Figure 4 Also shown is an enlarged view of a section of the functional housing connection surface 15 with the first axial seal 29. Identical elements are denoted by the same reference numerals as in the preceding figures.

[0060] The first soft component 31 arranged in the groove 32 is configured as an O-ring, for example. Alternatively, the first soft component 31 can also be arranged in the groove 32 by a molding process, for example, by an injection molding process. The groove 32 and the first soft component 31 extend laterally around the second opening 23 in the functional housing connection surface 15. The groove 32 and the first soft component 31 also laterally surround all functional connection elements 21 and all radial seals 28.

[0061] In order to improve the fixation of the first soft component 31 in the groove 32, the first axial seal 29 has a retaining lug 33. The retaining lug 33 is formed by the first soft component 31. The retaining lug 33 is, for example, alternately arranged on opposite sides of the first soft component 31, but it can also be arranged in a different way. However, the retaining lug 33 can also be omitted.

[0062] Figure 5 The fourth functional module 10 is schematically shown in a perspective view, wherein the fourth functional module 10 is shown in an assembled state and in a non-assembled state. Figure 5 The fourth functional module 10 is shown only as an example for explaining the radial seal 28 of the automation platform 1. For this reason, the following description applies to all functional modules 3 and their radial seals 28 relative to the base module 2. Identical elements are denoted by the same reference numerals as in the previous figures.

[0063] The functional housing connection surface 15 has at least one engagement element 34 arranged at the second opening 23 and a sealing interface 35 extending around the second opening 23. Figure 5 In the exemplary embodiment of the functional housing 14 of the functional module 3, the functional housing connection surface 15 has at least one further engagement element 36 arranged at the second opening 23 and opposite the engagement element 34. However, the functional housing connection surface 15 can also have any number of engagement elements 34, 36 arranged at the second opening 23. However, for each second opening 23, at least one engagement element 34, 36 is provided. If the functional housing connection surface 15 of the functional module 3 has a plurality of second openings 23, at least one engagement element 34 is arranged at the respective second opening 23 in each case.

[0064] For example, the joining elements 34, 36 are cylindrical. The joining elements 34, 36 are configured to be open on the side facing away from the functional housing connection surface 15, as a result of which the functional housing 14 is accessible. Therefore, cooling air can be exchanged between the interior of the base housing 14 and the interior of the functional housing 14. For this reason, the joining elements 34, 36 can also be referred to as vents. However, the joining elements 34, 36 do not necessarily have to be open and must be vents. The joining elements 34, 36 can also have different shapes. It is relevant that the joining elements 34, 36 on the functional housing connection surface 15 protrude away from the functional housing 14.

[0065] The sealing interface 35 extends transversely 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 interface 35 is rigidly connected to the joining elements 34, 35 and is formed by the joining elements 34, 36 in the region of the joining elements 34, 36. In the region of the joining elements 34, 36, the sealing interface 35 extends on the side of the joining elements 34, 36 facing away from the second opening 23. In an alternative embodiment, the sealing interface 35 also transversely surrounds the joining elements 34, 36. In this case, the sealing interface 35 is not connected to the joining elements 34, 36, nor is it formed by the joining elements 34, 36 in sections.

[0066] The functional module 3 further comprises a cover structure 37 having a hard part 38 and a second soft part 39 arranged on the hard part 38. The hard part 38 has a frame 40 extending around the second opening 23 and at least one plug-in socket 41 connected to the frame 40. The second soft part 39 of the cover structure 37 is arranged on the side 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 part 39.

[0067] The second soft component 39 can be arranged on the hard component 38 by a molding process, for example by an injection molding process. In this case, the hard component 38 and the second soft component 39 are connected to each other in a material-locked manner. However, optionally, the second soft component 39 can also be configured as an O-ring. However, the material-locked connection between the hard component 38 and the second soft component 39 provides the advantage that during the assembly of the functional module 3 or the automation platform 1, the arrangement of the second soft component 39 on the hard component 38 can be omitted.

[0068] It is also possible to provide a plurality of plug-in sockets 41. Advantageously, the number of plug-in sockets 41 of the cover structure 37 is the same as the number of engagement elements 34, 36 of the functional housing connection surface 15. For this purpose, according to Figure 5 The cover structure 37 of the exemplary embodiment has another plug-in socket 42, which is connected to the frame 40 and arranged on the side of the frame 40 opposite to the plug-in socket 41. The plug-in sockets 41, 42 are open on the side facing away from the frame 40, whereby the plug-in sockets 41, 42 and the engaging elements 34, 36 can each be used as a vent, although this is not absolutely necessary.

[0069] During the assembly of the functional module 3, the functional housing connection surface 15 is arranged on the functional housing 14 in such a way 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 so as to be connected to the base connection element 20. During the assembly of the functional module 3, the insertion sockets 41, 42 are attached to the functional housing connection surface 15 in such a way that the engagement elements 34, 36 are respectively inserted into the insertion sockets 41, 42 and engaged therein. For this reason, the insertion sockets 41, 42 have a geometry similar to the engagement elements 34, 36. In each case, the latching hooks 43, 44 are arranged on the walls of the insertion sockets 41, 42. The latching hook 43 of the insertion socket 41 and the other latching hook 44 of the other insertion socket 44 are arranged on the opposite sides of the insertion sockets 41, 42.

[0070] In each case, recesses 45, 46 are arranged on the wall of the engagement elements 34, 36. The recess 45 of the engagement element 34 and the other recess 46 of the other engagement element 36 are arranged on opposite sides of the engagement elements 34, 36. If only one engagement element 34 and correspondingly only one insertion socket 41 are provided, the recess 45 and the latching hook 43 are arranged on the side of the engagement element 34 or the insertion socket 41 facing the second opening 23, respectively. The engagement elements 34, 36 are inserted into the insertion sockets 41, 42 in such a way that the second soft component 39 abuts against the outer wall of the sealing interface 35, and the latching hooks 43, 44 of the insertion sockets 41, 42 are engaged in the recesses 45, 46 of the engagement elements 34, 36, respectively.

[0071] In each case, the edges of the walls of the engagement elements which delimit the recesses 45 , 46 form respective stops 47 , 48 on the respective sides of the recesses 45 , 16 facing away from the functional housing connection surface 15 .

[0072] When the functional module 3 is mounted on the base module 2 and the connection device 16 between the functional housing 14 and the base housing 12 is opened, the second soft part 39 of the cover structure 37 positions the hard part 38 of the cover structure 38 on the functional housing connection surface 15, so that the locking hooks 43, 44 inserted into the sockets 41, 42 abut against the stops 47, 18 of the engagement elements 34, 36, respectively. The locking hook 43 abuts against the stop 47. Another locking hook 44 abuts against another stop 48.

[0073] Figure 6 Schematically shows the Figure 3 1 is a cross-sectional view of the corresponding automation platform 1, but only the fourth functional module 10 and the base module 2 are shown. The fourth functional module 10 is Figure 6 In Figure 3 is shown in more detail in . Figure 6 The fourth functional module 10 is shown only as an example in order to explain in more detail the principle of the radial seal 28 of the automation platform 1. However, for each other functional module 10, the automation platform 1 has at least one such radial seal 28, which is arranged between the base module 2 and the functional module 3. Figure 6 Also shown is an enlarged view of the region of the radial seal 28. Like elements are denoted by like reference numerals as in the preceding figures.

[0074] A protrusion 49 extending around the first opening 22 is formed in the base shell connection surface 13. The protrusion 49 is arranged on the side of the base shell connection surface 13 facing the inside of the base shell 12. The protrusion 49 can also be called a seat. When the functional module 3 is installed on the base module 2, with the connecting device 16 opened, the cover structure 37 engages into the first opening 22 in the base shell connection surface 13, so that the frame 40 of the hard part 38 of the cover structure 37 rests on the protrusion 49 in the base shell connection surface 13, and the outer wall of the sealing interface 35 is supported on the second soft part 39 of the cover structure 37, so that the functional shell connection surface 15 is spaced apart from the base shell connection surface 13. This is Figure 6 1 is not shown in the figure because in this case the automation platform 1 is shown in the assembled state, wherein the connection device 16 is closed. When the functional module 3 is mounted on the base module 2 and when the connection device 16 is open, the distance between the base housing connection surface 13 and the functional housing connection surface 15 can also be specified as the stroke. Figures 7 to 9 The stroke and its effect will be explained in more detail in the context of the method for assembling the automation platform 1. If the slot is to be sealed with a plug 57, the protrusion 49 can serve as a stop or depth limit for the plug 57.

[0075] In accordance with Figure 6 When the connecting device 16 is closed, the functional housing connecting surface 15 is pressed against the base housing connecting surface 13, so that the second soft component 39 of the cover structure 37 is radially pressed in the area between the protrusion 49 in the base housing connecting surface 13 and the outer wall of the sealing interface 35, and the coupling elements 34, 36 of the functional housing connecting surface 15 are respectively pushed into the insertion sockets 41, 42 of the hard component 38 of the cover structure 37, so that the locking hooks 43, 44 of the insertion sockets 41, 42 are respectively spaced apart from the stops 47, 48 of the coupling elements 34, 36.

[0076] The second soft component 39 rests against the sealing interface 35, thereby forming a first radial barrier against dust, moisture or chemicals. Figure 6 In an exemplary embodiment of the present invention, the sealing interface 35 can taper at least in sections from the functional housing connection surface 15. The second soft part 39 of the cover structure 37 abuts against the outer wall of the sealing interface 35 in the region of the tapered portion. As a result, a more effective pressing of the second soft part 39 can be achieved. In addition, the second soft part 39 abuts against the wall above the protrusion 39, which defines the first opening 22 in the base housing connection surface 13. This forms a second radial barrier. Figure 6 The second seal 28 is shown in a compressed and uncompressed state to illustrate the sealing effect. Figure 6The portion of the second soft component 39 overlapping the sealing interface 35 in FIG. 1 represents the geometry of the second soft component 39 in the uncompressed state. In the compressed state, the second soft component 39 only extends to the sealing interface 35.

[0077] In the fourth functional module 10, the functional housing connection surface 15 is configured as a separate base plate 26. For this purpose, a second axial seal 30 is provided. The third soft component 50 is arranged between the functional housing connection surface 15 and the side wall 25 of the functional housing 14. The third soft component 50 can be arranged on the edge 51 of the functional housing connection surface 15, for example, by a molding process, for example, by an injection molding process. Optionally, the third soft component 50 can be attached to the edge 51 of the functional housing connection surface 15.

[0078] When the fourth functional module 10 is mounted on the base module 2, the third soft component 50 is arranged on the base housing connection surface 13 when the connection device 16 is open, and when the connection device 16 is closed, the third soft component 50 is pressed against the base housing connection surface 13. This forms a second axial barrier to prevent dust, moisture or chemicals. In addition, the third soft component 50 abuts against the side wall 25 of the functional housing 14, thereby forming a third radial barrier.

[0079] According to an exemplary embodiment of the fourth functional module 10, the side wall 25 of the functional housing 14 has another protrusion 52 on the inner side of the functional housing 14. For example, a groove-shaped recess 53 is formed between the other protrusion 52 and the side wall 25, however, the recess 53 may also be omitted. When the fourth functional module 10 is mounted on the base module 2, when the connecting device 16 is opened, the third soft component 50 abuts against the other protrusion 52. When the connecting device 16 is closed, the third soft component 50 is pressed against the other protrusion 52. This forms a third axial barrier. However, it is not necessary to provide a further protrusion 52 and it may also be omitted. To illustrate the sealing effect, Figure 6 Also shown is a third soft component 50 in a compressed and uncompressed state. Figure 6 The portion of the third soft component 50 overlapped by the protrusion 52 indicates an uncompressed state.

[0080] The functional housing connection surface 15 also has an additional protrusion 54 protruding in the direction of the side wall 25 of the functional housing 14. The additional protrusion 54 is embedded in the third soft component 50. When the fourth functional module 10 is mounted on the base module 2, when the connecting device 16 is opened, 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 against the additional protrusion 54. Thus, 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 13 facing the base housing connection surface 15. In addition, when the functional housing connection surface 15 is connected to the side wall 25 of the functional housing, a third radial barrier is formed in the area where the third soft component 50 is pressed against the edge 51 of the functional housing connection surface 15.

[0081] Figures 7 to 9 Schematically shows the Figure 2 The cross-sectional view of FIG. 1 is used for successive states in the context of a method for assembling an automated platform 1. The fourth functional module 10 is shown only as an example in order to explain the role of the radial seal 28 during assembly.

[0082] Figure 7 The state in which the functional module 3 and the base module 3 are separated from each other is shown. In this case, the second soft part 39 of the cover structure 37 arranges the hard part 38 of the cover structure 37 on the functional housing connection surface 15, so that the locking hooks 43, 44 inserted into the sockets 41, 42 abut against the stops 47, 48 of the engagement elements 34, 36 respectively.

[0083] Figure 8 The following diagram shows the time-dependent process after the functional module 3 is installed on the base module 2. Figure 7 However, the connecting device 16 is in the open state. Therefore, the functional module 3 only rests on the base module 2, rather than being pressed against the base module 2.

[0084] In this case as well, the second soft part 39 of the cover structure 37 arranges the hard part 38 of the cover structure 37 on the functional housing connection surface 15 so that the latching hooks 43, 44 inserted into the sockets 41, 42 respectively abut against the stops 47, 48 of the engagement elements 34, 36. This is because the second soft part 39 has not yet been pressed, because the connection device 16 is open.

[0085] The cover structure 37 engages in the first opening 22 in the base housing connection surface 13, so that the frame 40 of the hard part 38 of the cover structure 37 rests on the protrusion 49 in the base housing connection surface 13, and the outer wall of the sealing interface 35 is supported on the second soft part 39 of the cover structure 37, so that the functional housing connection surface 15 is spaced apart from the base housing connection surface 13. This distance can also be referred to as the stroke 55.

[0086] Figure 8 Also shown is an enlarged view of the region of the latching hook 43 resting against the stop 47. In the enlarged view, the travel 55 between the base housing connection surface 13 and the functional housing connection surface 15 is also shown. The travel 55 is likewise a result of the fact that the second soft part 39 is not yet compressed in this state.

[0087] As a result, during the insertion or installation of the functional module 3 , the second soft component 39 remains in an uncompressed state, so that the functional module 3 can be installed almost frictionlessly and therefore without force.

[0088] Fig. 9 The diagram shows the time following after the connection device 16 is closed. Figure 8 The functional module 3 is connected to the base module 2. Figure 6 As shown, Fig. 9 Also shown is the second seal 28 in both compressed and uncompressed states, which is why Fig. 9 Also shown in FIG. 3 is a portion of the second soft component 39 that overlaps the sealing interface 35 , and shows the geometry of the second soft component 39 in an uncompressed state.

[0089] By closing the connection device 16, the functional housing connection surface 15 is pressed against the base housing connection surface 13, so that the second soft part 39 of the cover structure 37 is radially pressed in the area between the protrusion 49 in the base housing connection surface 13 and the outer wall of the sealing interface 35. In this case, the engagement elements 34, 36 of the functional housing connection surface 15 are pushed into the insertion sockets 41, 42 of the hard part 38 of the cover structure 37, so that the locking hooks 43, 44 of the insertion sockets 41, 42 are spaced apart from the stops 47, 48 of the engagement elements 34, 36, respectively. Fig. 9 An enlarged view in the area of ​​one of the latching hooks 44 and the distance 56 to the corresponding stop 48 are shown. Thus, the functional module 3 is pulled into the end position by the connecting device 16 only shortly before the functional housing connecting surface 15 comes to bear against the base housing connecting surface 13. Only then does the radial seal 28 produce a sealing effect. The functional module 3 can thus be installed with little effort. This can simplify the insertion or installation of particularly large functional modules 3 with a plurality of functional connecting elements 21 and radial seals 28. In addition, the radial seal 28 is less subject to wear during assembly.

[0090] When the connecting device 16 is opened or released again, the second soft component 39 is pressed on the outer wall of the sealing interface 35 in such a way that the functional housing connection surface 15 is spaced apart from the base housing connection surface 13, and the locking hooks 43, 44 are against the stops 47, 48 of the engaging elements 34, 36. Therefore, when the pressure generated by the connecting device 16 on the second soft component disappears, the second soft component 39 presses the functional housing 14 into an unassembled state, and there is no longer a large friction between the functional module 3 and the base module 2. When the connecting device 16 is released, the second soft component 39 has been pressed on the functional module 3 with a force component, so that the release of the functional module is supported and can be achieved with little force consumption. Only then can the cover structure 37 be entrained on the locking hooks 43, 44. Thus, the functional module 3 can be released more easily from the base module 2 by the stroke 55 , since the functional module 3 can already be pulled out according to the stroke 55 , but the cover structure 37 initially remains in its position since the latching hooks 43 , 44 are initially spaced apart from the stops 47 , 48 .
