Description

Method, device and use for separating, aligning and inserting a runner cover of a stator
Technical Field
The present invention relates to a separation method implemented in the process of manufacturing a stator to separate a slot cover slider for covering stator slots provided with conductors for forming coil windings. The invention also relates to an insertion method implemented in the stator manufacturing process for inserting slot cover sliders into stator slots in order to cover conductors located therein using the above-described separation method. The invention also relates to a separating device for carrying out the separating process and to the use of such a separating device in the manufacture of a stator.
Background
Regarding the technical background of the slot cover slider and the manufacturing method of the stator using the slot cover slider, please refer to the following documents:
DE102017101381A1;
DE102017002420A1;
DE102016111478B4;
DE102016124534B4;
DE102016113894A1;
DE102016111482B4;
DE102017119838A1。
The stator of an electric machine typically has a stator component formed of a laminated core having stator slots in which conductors of the coils are accommodated. In some stators, individual stator slots provided with conductors are each covered by slot cover slides inserted into the stator slots. The slot cover slides are strip-shaped such that they extend in the longitudinal direction with their largest dimension. The outer contour and cross section of the slot cover slider are designed to correspond to the insertion position at the stator slot. For example, the slot cover slider has side surfaces extending in the longitudinal direction, one of which faces the interior of the stator slot in the intended use and the other of which faces the rotor of the electric machine.
The slot cover slides are difficult to handle due to their design because they have a rod-like, narrow geometry and often have rounded corners. Furthermore, they are generally provided as bulk materials (bulk materials) without a fixed orientation. Very precise orientation is required to insert the cover slider.
In the actual process currently used by various manufacturing companies, the slot cover slides are separated from the bulk material supply source (e.g. KLT (small load) containers or the like) with great effort by hand and inserted into the correctly positioned cartridges. For example, in this process, the worker individually removes the lid slide from the box and places it into the magazine, which is very time-consuming and requires a large number of workers (depending on the cycle time). The slot cover slides can then be further automated by positioning the cartridge in front of the stack of stator layers and inserting the cover slides.

Detailed Description
Various embodiments of the separation method and the advantageous separation device 10 are explained below with reference to the drawings. The separation method may be implemented particularly advantageously using one of the illustrated embodiments of the separation device 10, but may also be implemented in other ways.
The separation method is a method of separating and preferably providing the slot cover slider 12 at a correct position during the manufacturing of the stator 14. The slot cover slider 12 is designed to cover the stator slot 16, the stator slot 16 being provided with conductors for forming a coil winding.
The separation method comprises the following steps:
a) Providing a number 18 of strip-shaped slot cover slides 12 such that the slot cover slides 12 are aligned with each other in the longitudinal direction or are present in a disordered state as bulk material;
b) Providing a separating tool (referred to herein as counterpart 20) having an upwardly facing surface 22, the surface 22 having at least one upwardly opening slot 22, the slot 22 being complementarily adapted to the shape of the slot cover slider 12;
c) The number 18 of slot cover slides 12 are arranged parallel to the at least one slot 24;
d) Relatively moving the number 18 of slot cover slides 12 and the counterpart 20 in a direction transverse to the longitudinal extension of the slot 24, and the slot cover slides 12 are aligned with the longitudinal extension of the slot 24 such that the number 18 of slot cover slides 12 move over the area of the surface 22 provided with the slot 24;
e) The slot cover slide 12 is inserted into the slot 24 such that the angular position of the slot cover slide 12 relative to it about its longitudinal central axis is aligned in the slot 24.
The names of steps a), b), c), etc. are for ease of reference only and do not indicate a particular order of steps. Preferably, steps a) and c) are performed in combination by providing the number 18 of slot cover slides already in a position parallel to the slots on the surface 22. This can be achieved by providing a container in which the number 18 is accommodated and which is movable relative to the counterpart 20, or the slot cover slider 12 is placed on the surface 22 (in particular in the longitudinal direction relative to each other) and oriented in the direction of the slot and then moved over the surface relative to the counterpart 20. The relative movement between the number 18 of slot cover slides 12 and the counterpart 20 may be achieved by moving the number 18 of slot cover slides 12 when the counterpart 20 is stationary. Alternatively, this is achieved by moving the counterpart 20 when the number 18 is stationary, or alternatively by moving the counterpart 20 and the number 18 of slot cover slides 12 in opposite directions.
During this movement, the slot cover slide 12 is inserted into the slot 24 or into one of several slots 24 in the surface 22 of the counterpart 20. The slot cover slides 12 were previously aligned only in the longitudinal direction, otherwise arranged in a disordered manner in this number 18, and then, by the outer contour of the slot cover slide 12 mating the complementary shape of the slot, the slot cover slide 12 is also aligned in the slot 24 with respect to its position in cross section. Thus, the slot cover slide 12 is also aligned in the slot 24 with respect to its angular position about its longitudinal central axis (i.e., rotational position with respect to its longitudinal axis).
The figures show cross-sections of different embodiments of the separating apparatus 10, respectively, wherein the cross-sections extend transversely to the longitudinal axis or longitudinal central axis of the slot 24 and transversely to the longitudinal axis or longitudinal central axis of the slot cover slide 12 aligned parallel to the slot 24. The corresponding components of the separation device 10 are each provided with corresponding reference numerals and are each described only once. The different features of the different embodiments of the separating apparatus 10 may be combined with each other as desired.
In the various embodiments shown in the figures, the separating apparatus 10 has a separating tool (referred to herein as a counterpart 20) and an optional moving apparatus 28. The counterpart 20 has an upwardly facing surface 22 and at least one slot 24 formed in the surface 22. The moving means 28 is configured to relatively move the number 18 of slot cover slides 12 and the counterpart 20 aligned with the longitudinal direction of the slot 24 so as to move the number 18 of slot cover slides 12 over the slot 24. In some embodiments, an optional container 26 is provided.
Fig. 1 shows a first embodiment of a separation device 10. The separating apparatus 10 has a receptacle 26 for the slot cover slide 12, the counterpart 20 and the displacing means 28. The slot cover slide 12 is longitudinally aligned but not precisely oriented with respect to the rotational position (angular position) about the longitudinal axis. The container 26 is pivotable here by means of a displacement device 28 and can be pivoted from side to side in the counterpart 20. In this case, the surface 22 is curved in an arc shape. Slots 24 that match the geometry of the corresponding slot cover slides 12 are located in the counterpart 20, and thus the counterpart 20 is hollow. The moving means 28 have a pivoting drive, not shown in detail, for pivoting the container 26 back and forth.
The container 26 is elongated to accommodate a plurality of strip-shaped slot cover slides 12. For example, the container 26 is box-shaped or funnel-shaped. The container 26 has an elongated dispensing opening 30. Thus, the slot cover slides 12 are longitudinally aligned in the container 26 or present in a disordered state as bulk material. In particular, the angular position of the slot cover slide 12 about the longitudinal axis remains unoriented. Thus, the slot cover slide 12 can simply be poured into the container 26 from above. The container 26 is an example of a supply device 32 for supplying the number 18 of slot cover slides 12, which slot cover slides 12 are aligned with each other in their longitudinal direction, or may also be present as bulk material. By arranging the container 26 parallel to the slot 24, the slot cover slide 12 may be aligned entirely parallel to the slot 24 (for performing the example of step c).
At the dispensing opening 30, the container 26 has at least one scraper 34. In the embodiment shown, a scraper 34 is provided on each longitudinal side of the dispensing opening 30. The blade 34 may be designed differently, preferably the blade 34 is designed as a strip with a flexible region for sweeping across the surface 22. It is particularly preferred that the scraper 34 has in each case at least one brush 36.
During pivoting over the slot 24, the slot cover slide 12 separates in the slot 24. Fig. 2a to 2d show the various steps of inserting the slot cover slide 12 into the slot 24. The slot cover slide 12 is pushed through the surface 22 by the scraper 34/brush 36 up to the slot 24 and then inserted into the slot 24. In the slot 24, the outer contour of the slot cover slide 12 cooperates with the complementary shape of the slot so as to be aligned in its rotational or angular position relative to its longitudinal axis.
In some embodiments, such as shown in fig. 1, 3, 5-7, the surface 22 of the counterpart 20 has a radius/diameter 40, which radius/diameter 40 is adapted to the stator 14, or more precisely to the stack 38 thereof, as shown in fig. 7. This means that the slot cover slide 12 can be inserted into the stator 14 in the correct position. This means that no further redirection is necessary.
As shown in the embodiment of fig. 3, a number of slots 24 may also be formed on the surface 22, preferably so that their position and spacing is adapted to the position and spacing of the stator slots 16. Thus, the separation and alignment in several slots 24 may occur simultaneously, and the insertion of slot cover slides 12 from slots 24 into the respective stator slots 16 may also occur simultaneously. Thus, the counterpart 20 can be expanded by the further slot 24 and, thus, several slot cover slides 12 can be separated by one pivoting movement and then simultaneously inserted.
As shown in the embodiment of fig. 4, the surface 22 of the counterpart 20 may also be designed to deviate from the curvature of the stack 38 (in this case, for example, linearly). The moving means 28 then moves the number 18 of slot cover slides 12 linearly relative to the counterpart 20, for example by moving the container 26 linearly back and forth over the counterpart 20.
As shown in fig. 4, the counterpart 20 can also be designed flat without a radius if there is only one slot 24. With a linear design, it is also possible to provide for the reorientation of the slot cover slider during insertion by means of an additional template (not shown) to accommodate the position in the stator slot. Thus, it is also possible to provide a plurality of slots 24 in this flat design, in which case the slot cover slider 12 is simultaneously transferred into the stator slot 16 and can be redirected by the additional template.
As described above, the moving means 28 may be designed to move the number 18 of slot cover slides 12 over the surface 22 when the counterpart 20 is stationary, as shown in the embodiments of fig. 1 to 4, 6 and 7. However, as shown in the embodiment according to fig. 5, the displacement device 28 can also be designed to displace the counterpart 20 when the number 18 of slot cover slides 12 is stationary, or to displace the counterpart 20 in the opposite direction, in particular to oscillate the counterpart 20 back and forth.
Fig. 6 shows another embodiment of the separation device 10 without the need for a container 26. The supply device 32 is here essentially formed by the separating tool (referred to herein as counterpart 20) on which the number 18 of slot cover slides 12 can correspondingly be placed in the longitudinal direction of the slot 24. Here, the moving device 28 has a pusher or the like, such as a vane 44 that can be rotated or pivoted back and forth about a rotation axis 42.
Here, the slot cover slider 12 is directly filled into the counterpart 20 and guided through the slots 24 by the blades 44 or the like (a design with only one slot 24 is also possible). The number 18 of slot cover slides 12 pushes a single slot cover slide 12 through the slot 24 in motion, wherein the single slot cover slide 12 is placed in the open slot 24 and separated. Thus, the blade 44 or the like does not have to extend to the surface 22 of the counterpart 20. In some embodiments, not shown, it may also be advantageous in some cases for the vanes 44 to extend to the bottom (i.e., to the surface 22 in this case).
In other embodiments not shown, it is also provided that the separation process is optimized in this case by using a scraper 34 (e.g. with additional brushes 36 on the blades 44).
Fig. 7 shows a process of inserting the slot cover slider 12 into the stator slot 16 in order to cover the conductor located in the stator slot 16 during the manufacturing method of the stator 14, the process comprising:
Providing an annular stator component (e.g., layer stack 38) having stator slots 16, conductors (not shown) being received in the stator slots 16 to form coil windings;
The separated slot cover slider is provided by performing the separation process as described above. In this case, the separate slot cover slide is provided by placing the counterpart 20 together with the single slot cover slide 12 in the correct position received in the at least one slot 24;
The corresponding slot cover slider 12 is transferred from the slot 24 in the surface 22 into the stator slot 16 so as to cover the conductor.
For this purpose, the following steps are preferably performed:
f) Aligning at least one slot 24 in the separating tool with at least one stator slot 16, in particular by rotating the stator part about the stator part axis until the slots 24, 16 are aligned with each other; and
G) The corresponding slot cover slide 12 is moved longitudinally from the slot 24 of the separating tool into the stator slot 16 aligned therewith.
In order to significantly simplify and in particular automate the handling of the slot cover slider (12), the invention describes a separation method performed during the manufacturing of a stator (14) for separating the slot cover slider (12) to cover a stator slot (16) provided with conductors for forming a coil winding, the separation method comprising the steps of:
