DETAILED DESCRIPTION

[0072] In the following description and in the figures, corresponding components and elements bear the same reference signs. For improved clarity, not all reference signs are reproduced in all figures.

[0073] FIG. 1 shows an exploded view of a planar drive system 10. In the present case, the planar drive system 10 comprises nine stator modules 12, a frame 14 and a cover plate 42.

[0074] In the present case, the frame 14 has nine receptacles 24, wherein each of the receptacles 24 is configured to each be able to receive a stator module 12.

[0075] In the present case, the frame 14 is constructed from a plurality of frame elements 40. The frame elements 40 also form the receptacles 24 arranged in a checkerboard pattern. The frame elements 40 represent the walls of the receptacles 24.

[0076] FIG. 2 shows the planar drive system 10 according to FIG. 1 in a partially assembled state. Eight of the nine stator modules 12 have been inserted into the respective receptacles 24 of the frame 14 along an insertion direction 15. The insertion direction 15 is marked in FIGS. 1 and 2 by means of an arrow.

[0077] The cover plate 42 in the present case has an edge 43. Thus, the cover plate 42 covers the frame 14 and the stator modules 12 received in the receptacles 24 of the frame 14 in the assembled state from above and laterally.

[0078] FIG. 3 shows a stator module 12, a mounting plate 22 and a locking mechanism 26 in an exploded view, and FIG. 4 shows these components in the assembled state.

[0079] The stator module 12 has a base body 16 with a transport surface 18 (cf. FIGS. 7 and 9). The base body 16 has a rear side 20 opposite the transport surface 18. The base body 16 has four side surfaces 38, which are arranged orthogonally to the transport surface.

[0080] A mounting plate 22 is mounted on the rear side 20 of the base body 16 and is screwed to the base body 16 by means of four screws 36. In the present case, two dowel pins 35 are inserted at two opposite corners of the mounting plate 22 and connect the mounting plate 22 to the base body 16 (or the rear side thereof 20).

[0081] In the present case, the locking mechanism 26 is arranged in the mounting plate 22. The locking mechanism 26 consists of eight pivotable elements 28, which in the present case are designed in the form of closure hooks 34. Two of the pivotable elements 28 are each arranged opposite one another on the mounting plate 22.

[0082] The pivotable elements 28 are shown in the present case in a closed position 30 (cf. FIGS. 9 and 10). In the closed position 30, the pivotable elements 28 project from the mounting plate 22 or from the base body 16 of the stator module 12. In other words, the pivotable elements 28 are pivoted out in the closed position 30. In the closed position 30, the stator modules 12 fastened to the mounting plate 22 are locked within the receptacles 24.

[0083] FIG. 5 shows a perspective view of a stator module 12 and a receptacle 24. In the present case, four frame elements 40 form the receptacle 24. The frame elements 40 thus represent the walls of the square receptacle 24. The frame elements 40 have recesses 32, which in the present case are in the form of elongated holes.

[0084] For inserting the stator module 12 into the receptacle 24, the locking mechanism 26 is transferred into a release position 31, in which the pivotable elements 28 of the locking mechanism 26 are pivoted. In other words, the pivotable elements 28 no longer protrude from the mounting plate 22 or from the base body 16 of the stator module 12.

[0085] In the release position, the pivotable elements 28 of the locking mechanism 26 do not block the insertion of the stator module into the receptacle 24. The stator module 12 can thus be moved in the insertion direction 15 and can be inserted into the receptacle 24 with the transport surface 18 forward.

[0086] FIG. 6 shows a view from below of the stator module 12 and the receptacle 24 according to FIG. 5. A section A-A is marked by means of a dashed line.

[0087] FIG. 7 shows a section A-A from FIG. 6, and FIG. 8 shows a detail X from FIG. 7.

[0088] In FIGS. 7 and 8, the stator module 12 including the mounting plate 22 and the locking mechanism 26 has been inserted into the receptacle 24, which is formed by the frame elements 40. The locking mechanism 26 is in the release position 31.

[0089] As can be seen particularly well from FIG. 8, the pivotable elements 28 of the locking mechanism 26 are pivoted into the release position 31 and do not engage in the recesses 32 of the frame elements 40. The stator module 12 is therefore inserted in the receptacle 24, but not yet locked in the receptacle 24. The stator module 12 can be moved back and forth along the insertion direction 15 as long as the locking mechanism 26 is in the release position 31.

[0090] FIG. 9 shows a section A-A from FIG. 6, and FIG. 10 shows a detail Y from FIG. 9.

[0091] In FIGS. 9 and 10, the stator module 12 including the mounting plate 22 and the locking mechanism 26 has been inserted into the receptacle 24, which has been formed by the frame elements 40. The locking mechanism 26 is in the closed position 30.

[0092] In the closed position 30, the pivotable elements 28 are pivoted out and engage in the recesses 32 of the frame elements 40. A positive-locking connection is produced in particular along the insertion direction 15. The stator module 12 is thus locked in the receptacle 24.

[0093] To remove the stator module, the pivotable elements 28 are pivoted in again. The locking mechanism 26 is thus transferred into the release position 31 (cf. FIG. 8). As soon as the locking device 26 is in the release position 31 and the friction locking between the pivotable elements 28 and the recesses 32 is canceled, the stator module 12 can be moved counter to the insertion direction 15 and removed from the receptacle 24 with the rear side 20 in front.

[0094] The pivotable elements 28 are pivotably accommodated along the pivot axes 29 thereof in the mounting plate 22 (cf. FIGS. 8 and 10). In the present case, the pivotable elements 28 have a slot 33 on their end facing away from the base body 16 of the stator module 12 (cf. FIG. 8). The pivotable elements 28 may thus be pivoted back and forth, for example by means of a flat-tip screwdriver, which engages in the slot 33 and is rotated. Accordingly, the locking mechanism 26 can in the present case be transferred from the release position 31 into the closed position 30 and vice versa by means of a flat-tip screwdriver.
