Description

[0001] The invention relates to a method for producing a device clamped with a tensioning band, wherein spaced-apart tensioning band regions of the tensioning band are arranged in a fastening recess of the device, and a fixing means is introduced into the fastening recess to secure the tensioning band regions in the fastening recess. The invention further relates to a manufacturing device for producing the device clamped with the tensioning band.

[0002] For example, the prior art document DE 10 2018 217 253 A1 is known. This document describes a method for producing a battery module for a traction battery, comprising the steps of: arranging a plurality of storage cells to form a cell stack, wherein a first pressure plate and a second pressure plate having a pocket-like recess are arranged at the ends of the cell stack; arranging at least one clamping band spanning the cell stack such that the two band ends of this clamping band are located at the pocket-like recess of the second pressure plate; pressing the cell stack in a closing device, wherein the band ends of the clamping band are pressed into the pocket-like recess and the pocket-like recess is injected with plastic or adhesive to permanently fix the band ends.

[0003] Furthermore, the document DE 10 2021 114 487 B3 shows a method for producing a module arrangement comprising a plurality of individual modules, comprising the steps of: arranging the individual modules to form a module stack at the ends of which a first pressure plate and a second pressure plate are positioned, wherein the second pressure plate has a deflection device for the band ends of a tensioning band; arranging a tensioning band spanning the module stack as well as the first pressure plate and the second pressure plate, the band ends of which are guided by the deflection device of the second pressure plate and deflected in opposite transverse directions; tensioning the tensioning band by applying tensile forces to the band ends; fixing the band ends of the tensioned tensioning band to the second pressure plate.

[0004] The object of the invention is to propose a method for producing a device clamped with a clamping band, which has advantages over known methods, in particular implementing a permanently reliable fixing of the clamping band in the fastening recess.

[0005] This is achieved according to the invention with a method for producing a device clamped with a tensioning band having the features of claim 1. It is provided that before the fixing means is introduced into the fastening recess, the tensioning band and / or a device region of the device delimiting the fastening recess are heated by means of a heating device.

[0006] Advantageous embodiments with useful further developments of the invention are specified in the dependent claims. It should be noted that the exemplary embodiments explained in the description are not limiting; rather, any variations of the features disclosed in the description, the claims, and the figures are feasible.

[0007] The method serves to produce the device which is clamped with the clamping band. The device has an element arrangement and the clamping band, wherein the element arrangement comprises one or more elements to be clamped. First, the element arrangement is provided in the form of at least one element and then the clamping band is arranged around the element arrangement. The element arrangement is then clamped, for example by applying a clamping force to the clamping band which is directed towards compressing the element arrangement, or by pressing the element arrangement using a press. The clamping band is then fastened to the element arrangement in such a way that it grips it tightly, in particular continues to exert a clamping force on the element arrangement. The clamping band is then fastened to the element arrangement.

[0008] The clamping band is secured by first inserting the clamping band sections, which are spaced apart from one another on the clamping band, into the fastening recess and then inserting the fixing means into these sections. The clamping band sections are, for example, the clamping band ends of the clamping band, but they can also be spaced apart from the clamping band ends, so that the clamping band ends are outside the fastening recess. By inserting the fixing means into the fastening recess, the clamping band sections are fixed with respect to the element arrangement, so that the clamping band subsequently counteracts any expansion of the element arrangement.

[0009] To secure the clamping band particularly reliably and permanently in the mounting recess, the clamping band or the mounting area is preheated using the heating device before the fixing agent is introduced into the mounting recess. Preheating the clamping band or the mounting area improves the bond between the fixing agent and the clamping band or the mounting area. Furthermore, the heating allows for easier insertion of the fixing agent, as it is more effectively distributed within the mounting recess.

[0010] Preferably, the heating is carried out in such a way that the tensioning band and / or the device area are at least partially melted, so that a direct material-to-material connection between the tensioning band and the device area and / or the fixing means is established. This further improves the holding effect of the fixing means. Such a procedure is particularly advantageous if the tensioning band is multi-layered, i.e. several layers of the tensioning band lie directly against one another. In this case, the heating is preferably carried out in such a way that at least some of the layers, preferably all layers of the tensioning band, are materially bonded to one another. This prevents, for example, a middle layer of the tensioning band, which is arranged between two other layers and is connected neither to the device nor to the fixing means, from continuing to move freely.This creates a particularly permanent connection between the tensioning strap and the element arrangement of the facility.

[0011] The device is, for example, a battery cell arrangement of a traction battery for a motor vehicle. The traction battery is preferably a component of the motor vehicle, but it can of course also be separate from the latter, in particular until the traction battery is mounted on or in the motor vehicle. The traction battery is provided and configured for the temporary storage of electrical energy for a drive device of the motor vehicle. The drive device serves to drive the motor vehicle, thus providing a drive torque directed toward driving the motor vehicle.

[0012] To provide the drive torque, the drive device has at least one drive unit, which is configured as an electric traction machine that is electrically connected to the traction battery. The electrical energy temporarily stored in the traction battery is used, at least temporarily, to drive the motor vehicle, i.e., to provide the drive torque directed toward driving the motor vehicle by means of the drive device or drive unit. Conversely, it can be provided that electrical energy generated by the drive device is temporarily stored in the traction battery.

[0013] The traction battery preferably has a battery housing and at least one cell module, the cell module being provided and configured for the intermediate storage of electrical energy. For this purpose, it has one or more battery cells, preferably a plurality of electrically interconnected battery cells. The battery cells are preferably configured as prismatic cells or pouch cells. A cell module receptacle is formed in the battery housing, which is provided and configured to receive the cell module. During the manufacture of the traction battery, the cell module is inserted into the cell module receptacle. Preferably, not just a single cell module is arranged in the battery housing, but rather several cell modules are inserted into the battery housing. In such a configuration, the battery housing has a cell module receptacle, which is configured to receive several cell modules, or several cell module receptacles.

[0014] The battery cell or battery cells of the cell module form a component of the battery cell arrangement. Additionally, the battery cell arrangement can comprise a cell module housing. For example, the cell module housing has at least two end plates that accommodate the battery cell or battery cells between them. To this extent, the end plates are arranged on opposite sides of the battery cell or battery cells. The battery cell or battery cells and the end plates are preferably elements of the aforementioned element arrangement, which is a component of the device to be clamped.

[0015] The battery cell arrangement is preferably cuboid-shaped or at least approximately cuboid-shaped. If the battery cell arrangement has multiple battery cells, these are preferably electrically interconnected. For this purpose, the battery cells are arranged, for example, such that their electrical connections are located on the same side. The connections are electrically connected to one another via a plurality of busbars, which are preferably also electrically connected to electrical connections of the cell module. In other words, the battery cells are electrically connected to the connections via the busbars.

[0016] Over time, the battery cell arrangement, i.e., the battery cell or cells, can expand, particularly during charging or discharging of the traction battery. This expansion can also be referred to as "swelling." To counteract this expansion, the battery cell arrangement is mechanically tensioned. For this purpose, the battery cell arrangement is subjected to a tensioning force using the tensioning band, which applies a contact pressure to the battery cell arrangement that opposes the expansion. The tensioning force counteracts the expansion force exerted on the tensioning band by the expansion of the battery cell arrangement.

[0017] Before the clamping band is secured relative to the battery cell arrangement, the battery cell arrangement is compressed. This means that, starting from first outer circumferential dimensions, which it has in the relaxed state, the battery cell arrangement is compressed by applying a pretensioning force to second outer circumferential dimensions that are smaller than the first outer circumferential dimensions. The dimensions of the battery cell arrangement are thus reduced in at least one direction by the compression, in particular in an imaginary plane. Preferably, the clamping band is arranged with a pretension around the compressed battery cell arrangement; the clamping band therefore already has a tension other than zero when its clamping band regions are secured in the fastening recess by means of the fixing means.

[0018] After the clamping band areas have been secured in the fastening recess using the fixing means, the battery cell assembly is released. The outer circumferential dimensions of the battery cell assembly increase from the second outer circumferential measurements toward the first outer circumferential dimensions. In particular, the clamping band is dimensioned such that it further compresses the battery cell assembly after the release of tension, so that the outer circumferential dimensions of the battery cell assembly after the clamping band has been applied and the battery cell assembly has been released are smaller than the outer circumferential dimensions of the fully released battery cell assembly before compression.

[0019] In particular, a plastic or a fiber composite material with a plastic matrix is used as the fixing agent. The fixing agent is preferably introduced into the fastening recess in a molten state and cooled there so that it hardens. Polyethylene, polypropylene or polyamide are particularly used as the plastic. The fiber composite material or the fiber-reinforced plastic has a plastic matrix and reinforcing fibers. The plastic matrix consists, for example, of polyethylene, polypropylene or polyamide or comprises these at least predominantly, i.e. at least 50 wt.%, at least 70 wt.% or at least 90 wt. The reinforcing fibers are, for example, glass fibers, carbon fibers or the like.

[0020] A further development of the invention provides that the fastening recess is defined by spaced-apart clamping edges, and one of the clamping band regions is applied to each of the clamping edges, so that the clamping band regions accommodate a gap between them that at least partially forms the fastening recess. The clamping edges define the fastening recess on opposite sides and are arranged at a corresponding distance from one another. In particular, the clamping edges are located on the end plate or one of the end plates. Particularly preferably, they run parallel to one another.

[0021] One of the clamping band areas is applied to each of the clamping edges, whereby the distance between the clamping edges is greater than the total material thickness of the clamping band areas, so that after the clamping band areas are applied to the clamping edges, the clamping band areas are arranged at a distance from one another and accommodate the space between them. The space between them at least partially forms the fastening recess. After the clamping band areas are applied to the clamping edges, the clamping band or the installation area, namely in particular the clamping edges, is heated. For example, this takes place in such a way that the clamping band areas form a materially bond with the respective clamping edge to which they are in contact.

[0022] In particular, heating of the clamping band takes place to a temperature at which it at least partially melts, in particular the plastic matrix of the clamping band melts. After heating, the fixing agent is preferably introduced immediately into the fastening recess and thus into the intermediate space, i.e., before the clamping band or the device area cools down again. This achieves a particularly reliable connection between the clamping band and the device or the element arrangement.

[0023] A further development of the invention provides that the clamping edges are arranged at an angle relative to a main extension direction of the clamping band. The main extension direction of the clamping band is understood to be the direction in which the clamping band has its largest dimensions, in particular its longitudinal direction. In particular, the main extension direction is perpendicular to a direction in which the material thickness of the clamping band exists, as well as perpendicular to a direction in which the clamping band has a width. The main extension direction of the clamping band thus defines its length.

[0024] The clamping edges are angled relative to the main direction of extension, thus forming an angle with it that is greater than 0° and less than 180°. Preferably, the angle is at least 15° and at most 75°, at least 30° and at most 60°, or approximately or exactly 45°. The clamping edges are thus aligned in such a way that the clamping band areas adjacent to them are deflected. Such a configuration enables particularly reliable securing of the clamping band areas and / or the clamping band encompassing the device or element arrangement in different planes.

[0025] A further development of the invention provides for the use of a multi-layer tensioning strap and / or a tensioning strap made of fiber composite material as the tensioning strap. The multi-layer tensioning strap has several layers arranged one above the other, in particular adjacent to one another. Preferably, the tensioning strap has several layers in each of the tensioning strap regions, each of which is applied together to the clamping edges of the fastening recess. By using the multi-layer tensioning strap, the clamping force achieved with the help of the tensioning strap can be significantly increased.

[0026] In addition or alternatively to the multi-layer design of the tensioning strap, the tensioning strap is made of a fiber composite material. The fiber composite material is preferably electrically insulating, so that additional electrical insulation between live areas of the traction battery and the tensioning strap can be dispensed with if necessary. The fiber composite material or the fiber-reinforced plastic has a plastic matrix and reinforcing fibers. The plastic matrix consists, for example, of polypropylene, polyethylene, or polyamide, or at least predominantly comprises them, i.e., at least 50% by weight, at least 70% by weight, or at least 90% by weight. The reinforcing fibers are, for example, glass fibers, carbon fibers, or the like.

[0027] The reinforcing fibers are preferably aligned at least partially or completely unidirectionally, particularly preferably in the longitudinal direction of the tensioning band or in the circumferential direction of the battery cell arrangement. This means that the reinforcing fibers at least partially or even completely encompass the battery cell arrangement in the direction of their largest dimensions. The tensioning band is thus a unidirectional tensioning band. Continuous fibers or long fibers are preferably used as the reinforcing fibers. This allows the tensioning band to absorb particularly high tensile forces, thus reliably preventing expansion of the device or element arrangement.

[0028] A further development of the invention provides that a heating fluid is introduced into the fastening recess by means of the heating device and / or a heating element of the heating device is applied to the device to heat the tensioning band and / or the device area. Heating can take place in various ways. Firstly, the heating fluid can be discharged from the heating device, namely in such a way that it flows against and / or over the tensioning band and / or the device area. The heating fluid is, in particular, air. Before discharge, it is heated to a temperature sufficient to heat the tensioning band or the device area. The heat required for heating is thus transferred convectively.

[0029] Secondly, additionally or alternatively, the heating element can be applied to the device so that the tensioning band or the device area is heated. The heating element is preferably designed such that it lies against the tensioning band or the device area at least along an imaginary line or preferably flatly. For example, the heating element lies flatly against the tensioning band so that the latter is held clamped between the heating element and the device area, in particular the respective clamping edge. For this purpose, the heating element is preferably shaped to fit the tensioning band so that it lies against the tensioning band not only along an imaginary line, but rather across a surface. The heat required for heating is transferred conductively with the aid of the heating element.

[0030] For example, it is proposed to apply heat to the clamping band or the installation area both convectively and conductively. In this case, the heating fluid may first be applied to the clamping band or the installation area while the heating element is kept at a distance from it(s), and then the heating element is brought into contact with it(s). The described procedure reliably heats the clamping band or the installation area.

[0031] A further development of the invention provides that the fixing means is introduced into the fastening recess, in particular by means of the heating device, with the heating device resting against the tensioning strap and / or the fastening region. The heating device is arranged in such a way that it overlaps the fastening recess, in particular the intermediate space between the tensioning strap regions, as seen in cross-section, in particular completely, so that it is particularly preferably closed off by the heating device as seen in cross-section. For example, the heating device closes off most of the fastening recess as seen in longitudinal section, in particular by at least 80%, at least 90% or even completely. This achieves a particularly uniform distribution of the fixing means in the fastening recess.

[0032] Particularly preferred is a configuration of the heating device in which it is also used to introduce the fixing agent into the fastening recess. The heating device not only serves to heat the clamping band or the device area, but also to secure the clamping band areas in the fastening recess by introducing the fixing agent. This ensures that the clamping band is secured to the clamped device or the element arrangement of the device in a particularly efficient manner.

[0033] A further development of the invention provides that the heating device is arranged such that it completely overlaps the fastening recess in cross-section, in particular rests against the tensioning band on opposite sides of the fastening recess. Such a configuration of the heating device has already been mentioned. It serves, on the one hand, to uniformly and completely heat the tensioning band or the fastening area and, preferably, also to hold the fixing agent introduced into the fastening recess therein.

[0034] A further development of the invention provides that heating takes place by supplying hot fixing agent to the heating device. The fixing agent therefore serves not only to finally secure the tensioning band in the fastening recess, but also to heat the tensioning band or the fastening area, in particular without coming into direct contact with them. For this purpose, the hot fixing agent is preferably supplied to the heating device in such a way that it does not enter the fastening recess during heating, but remains in the heating device in order to heat the latter and thus also the tensioning band and / or the fastening area. Only after sufficient heating, for example to a certain temperature, is the fixing agent also introduced into the fastening recess, for example with the aid of the heating device. This results in a particularly high level of efficiency for the described method.

[0035] The invention further relates to a manufacturing device for producing a device clamped with a tensioning band, in particular for carrying out the method according to the explanations in the context of this description, wherein the manufacturing device is provided and configured to arrange spaced-apart tensioning band regions of the tensioning band in a fastening recess of the device and to introduce a fixing means into the fastening recess to secure the tensioning band regions in the fastening recess. The manufacturing device is further provided and configured to heat the tensioning band and / or a device region of the device delimiting the fastening recess by means of a heating device before introducing the fixing means into the fastening recess.

[0036] The advantages of such a design of the manufacturing device or such a procedure have already been pointed out. Both the manufacturing device and the method for its operation can be further developed according to the explanations in this description, so reference is made to these in this regard.

[0037] A further development of the invention provides at least one of the following elements as a component of the manufacturing device: a covering element for partially covering the fastening recess, an insulating element for thermally insulating the fastening recess from an external environment, a tempering element for tempering the fixing agent introduced into the fastening recess and a sensor device for detecting at least one measured value.

[0038] With the help of the cover element, the fastening recess is covered at least partially, preferably completely, while the fixing agent is introduced into it. This achieves a particularly even distribution of the fixing agent in the fastening recess. In addition, the fixing agent is separated from the external environment by the cover element, thus already providing a certain insulating effect and allowing the fixing agent to cool down more slowly. The insulating element serves to thermally insulate the fastening recess. For example, it is present in the form of the cover element or together with the cover element. The thermal insulation from the external environment delays the cooling of the fixing agent, resulting in greater process reliability.

[0039] Using the temperature control element, the fixing agent is temperature-controlled after it has been introduced into the fastening recess. For example, a specific temperature of the temperature control element is set, in particular according to a temperature profile over time. This allows the solidification of the fixing agent to be controlled in a controlled manner. The temperature control element can be designed together with the insulating element and / or the covering element. Additionally or alternatively, the production device has the sensor device. The sensor device is used to record at least one measured value, at least temporarily. For example, the sensor device has a temperature sensor, so that the measured value is available as a temperature. The measured value can be used to monitor the heating of the clamping band or the installation area and / or the cooling of the fixing agent.The measures mentioned serve to achieve a particularly high level of process reliability.

[0040] A further development of the invention provides that the heating device comprises or consists of at least one of the following materials: metal, polytetrafluoroethylene, and polyetheretherketone. As such, the heating device is extremely temperature-resistant and also has good thermal conductivity. Preferably, the heating device has a metal base body with a covering made of polytetrafluoroethylene and / or polyetheretherketone. This achieves a particularly uniform temperature distribution during heating.

[0041] The features and feature combinations described in the description, in particular the features and feature combinations described in the following description of the figures and / or shown in the figures, can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also to be considered encompassed by the invention that are not explicitly shown or explained in the description and / or the figures, but which emerge from or can be derived from the explained embodiments.

[0042] The invention will be explained in more detail below with reference to the exemplary embodiments shown in the drawings, without limiting the invention. In the drawings: Fig. 1 a schematic representation of a device tensioned with a tensioning strap, Fig. 2 a schematic detailed representation of a region of the device and a part of a manufacturing device for producing the device, as well as Fig. 3 a schematic sectional view of a portion of the device and a portion of the manufacturing apparatus.

[0043] The Fig. 1 shows a schematic representation of a device 1 in the form of a battery cell arrangement, which is clamped with a tensioning band 2. The device has an element arrangement 3, which is composed of several elements 4, only a few of which are identified by way of example. In the present exemplary embodiment, the first of the elements 4 are designed as battery cells 5 and the second of the elements 4 as end plates 6 of a cell module housing 7. The battery cells 5 are arranged between the end plates 6. The elements 4 of the element arrangement 3 are arranged adjacent to one another and are jointly encompassed by the tensioning band 2. In particular, the tensioning band 2 bears against one of the end plates 6 with a continuously closed region, whereas it bears against the other end plate 6 with separate tensioning band regions 8 and 9. The course of the tensioning band 2 is indicated by way of example using the arrows 10.

[0044] A fastening recess 11 is formed in one of the end plates 6, into which the clamping band areas 8 and 9 engage. In particular, the clamping band areas 8 and 9 abut opposite clamping edges 12 and 13, which delimit the fastening recess 11 on opposite sides. In the illustrated embodiment, the clamping edges 12 and 13 are angled relative to a main extension direction of the clamping band 2, indicated by the arrows 10. As a result, they deflect the clamping band 2 or the clamping band areas 8 and 9, so that the clamping band encompasses the element arrangement 3 in an additional plane according to the arrows 14.

[0045] Preferably, the clamping band 2 is divided into two sub-regions by the deflection effect of the fastening recess 11 or the clamping edges 12 and 13, which at least partially encompass, preferably completely, the element arrangement 3 in different planes. The planes are preferably angled relative to one another, thus forming an angle greater than 0° and less than 180°. For example, the angle is 90°, so that the sub-regions of the clamping band 2 enclose the element arrangement 3 in different directions or encompass it on different sides.

[0046] The Fig. 2 shows a schematic representation of the device 1 with the tensioning band 2 and a part of a manufacturing device 15 for manufacturing the device 1. The manufacturing device 15 has in particular a heating device 16, by means of which the tensioning band 2 and / or a device region 17, in particular comprising the tensioning edges 12 and 13, is heated, namely before a fixing agent is introduced into the fastening recess 11 for fixing the tensioning band 2 or the tensioning band regions 8 and 9 in the fastening recess 11.

[0047] The heating device 16 is preferably designed to heat convectively and / or conductively. In particular, it completely overlaps the fastening recess 11 as seen in cross-section, thus resting on the clamping band areas 8 and 9 on opposite sides of the fastening recess 11. On its side facing the device 1, the heating device 16 is shaped to the clamping band areas 8 and 9 so that it rests flat against the clamping band areas 8 and 9. For example, the heating device 16 is provided with a radius for this purpose, analogous to the clamping edges 12 and 13. The heating device 16 has a fluid channel 18 for a heating fluid, by means of which the heating device 16 is heated and / or which is discharged from the heating device 16 through corresponding outlet openings 19 (not shown here) in the direction of the clamping band areas 8 and 9.Preferably, the heating device 16 is designed to introduce the fixing means into the fastening recess 11.

[0048] The Fig.Figure 3 shows a schematic sectional view of the device 1 and the manufacturing apparatus 15. It can be seen that an air supply 20 is present, to which outlet channels 21 are fluidically connected, which are angled with respect to the air supply 20 and inclined in the direction of the clamping band areas 8 and 9 or the clamping edges 12 and 13. It is also clear that the heating device 16 already rests outside the fastening recess 11 on the clamping band areas 8 and 9 or the clamping edges 12 and 13 and thus completely overlaps, in particular closes, the fastening recess 11 as seen in cross-section. In addition, it extends into the fastening recess 11, for example, it penetrates walls of the element 4 on which the clamping edges 12 and 13 are present, by at least 50%, at least 60%, or at least 70%. For this purpose, the heating device 16 is designed in the shape of a stamp.

[0049] The described design of the device 1 or the manufacturing device 15 enables a particularly efficient clamping of the device 1 with the clamping band 2. In particular, it is particularly reliably possible to fasten a multi-layer clamping band 2 to the device 1 or its element arrangement 3.
