Description

[0001] The invention relates to a method for manufacturing a device tensioned with a tension band, wherein spaced-apart tension band sections of the tension band are arranged in a mounting recess of the device, and a fixing means is inserted into the mounting recess to secure the tension band sections in the mounting recess. The invention further relates to a manufacturing device for producing the device tensioned with the tension band.

[0002] For example, the prior art includes German patent application DE 10 2018 217 253 A1. This describes a method for manufacturing a battery module for a traction battery, comprising the following steps: arranging several storage cells into a cell stack, wherein a first pressure plate and a second pressure plate, which has a pocket-like recess, are arranged at the ends of the cell stack; arranging at least one tension band spanning the cell stack such that the two ends of this tension band are located at the pocket-like recess of the second pressure plate; pressing the cell stack in a clamping device, wherein the ends of the tension band are pressed into the pocket-like recess and the pocket-like recess is filled with resin or adhesive for permanent fixation of the band ends.

[0003] Furthermore, the publication DE 10 2021 114 487 B3 discloses a method for manufacturing a module arrangement comprising several individual modules, with the following steps: arranging the individual modules into a module stack at the ends of which a first pressure plate and a second pressure plate are positioned, the second pressure plate having a deflection device for the ends of a tension band; arranging a tension band spanning the module stack as well as the first pressure plate and the second pressure plate, the ends of which are guided through the deflection device of the second pressure plate and deflected in opposite transverse directions; tensioning the tension band by applying tensile forces to the ends of the band; fixing the ends of the tensioned tension band to the second pressure plate.

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

[0005] According to the invention, this is achieved by a method for manufacturing a device tensioned with a tension band and having the features of claim 1. It is provided that, prior to inserting the fixing means into the fastening recess, the tension band and / or a device area of ​​the device delimiting the fastening recess are heated by means of a heating device, wherein the fixing means is inserted into the fastening recess with the heating device in contact with the tension band and / or the device area.

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

[0007] The method serves to manufacture the device, which is tensioned with the tension band. The device comprises an element assembly and the tension band, wherein the element assembly includes one or more elements to be tensioned. First, the element assembly is provided in the form of at least one element, and then the tension band is arranged around the element assembly. Subsequently, the element assembly is tensioned, for example, by applying a tension force to the tension band, which is directed to compress the element assembly, or by pressing the element assembly using a press. The tension band is then fixed to the element assembly in such a way that it tightly grips it, in particular continuing to exert a tension force on the element assembly. Finally, the tension band is secured to the element assembly.

[0008] The tension band is secured by first inserting the spaced-apart sections of the tension band into the mounting recess and then inserting the fixing element into these recesses. The tension band sections can be, for example, the ends of the tension band, but they can also be spaced apart from the ends, so that the ends of the tension band are located outside the mounting recess. By inserting the fixing element into the mounting recess, the tension band sections are secured with respect to the element arrangement, so that the tension band subsequently counteracts any expansion of the element arrangement.

[0009] To ensure the tension band is securely and permanently fixed in the mounting recess, the tension band or the mounting area is preheated using the heating device before the fixing agent is applied. Preheating the tension band or mounting area improves the bond between the fixing agent and the tension band or mounting area. Furthermore, the heating facilitates the application of the fixing agent, as it spreads more effectively within the mounting recess.

[0010] Preferably, the heating is carried out in such a way that the tensioning band and / or the fixture area are at least partially melted, creating a direct, material-bonded connection between the tensioning band and the fixture area and / or the fixing agent. This further improves the holding effect of the fixing agent. Such a procedure is particularly advantageous if the tensioning band is multi-layered, i.e., if several layers of the tensioning band are in direct contact with 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, bond together materially. This prevents, for example, a middle layer of the tensioning band, which is arranged between two other layers and is not in contact with either the fixture or the fixing agent, from continuing to move freely.This creates a particularly durable connection of the tension band to the element arrangement of the facility.

[0011] The device is, for example, a battery cell arrangement of a traction battery for a motor vehicle. Preferably, the traction battery is an integral part of the motor vehicle; however, it can, of course, also exist separately, particularly until the traction battery is mounted on or in the motor vehicle. The traction battery is designed and configured for the intermediate storage of electrical energy for a drive system of the motor vehicle. The drive system serves to propel the motor vehicle, thus providing a drive torque directed toward propelling the motor vehicle.

[0012] To provide the drive torque, the drive system has at least one drive unit, which is designed as an electric traction machine and is electrically connected to the traction battery. The electrical energy temporarily stored in the traction battery is used, at least temporarily, to propel the vehicle, i.e., to provide the drive torque directed towards propelling the vehicle by means of the drive system or drive unit. Conversely, it may be provided that electrical energy generated by the drive system is temporarily stored in the traction battery.

[0013] Preferably, the traction battery comprises a battery housing and at least one cell module, wherein the cell module is designed and configured for the intermediate storage of electrical energy. For this purpose, it has one or more battery cells, preferably several electrically interconnected battery cells. The battery cells are preferably designed as prismatic cells or as pouch cells. A cell module receptacle is formed in the battery housing, which is designed 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 several cell modules are inserted into the battery housing. In such a configuration, the battery housing has a cell module receptacle designed to receive several cell modules, or several cell module receptacles.

[0014] The battery cell(s) of the cell module form part of the battery cell assembly. The battery cell assembly can also include a cell module housing. For example, the cell module housing has at least two end plates that accommodate the battery cell(s). The end plates are arranged on opposite sides of the battery cell(s). The battery cell(s) and the end plates are preferably elements of the aforementioned element assembly, which is part of the device to be clamped.

[0015] Preferably, the battery cell arrangement is cuboid or at least approximately cuboid. If the battery cell arrangement comprises several battery cells, these are preferably electrically interconnected. For this purpose, the battery cells are arranged, for example, such that their electrical terminals are on the same side. The terminals are electrically connected to each other via several busbars, which are preferably also electrically connected to electrical terminals of the cell module. In other words, the battery cells are electrically connected to the terminals via the busbars.

[0016] Over time, the battery cell assembly, i.e., the battery cell(s), can expand, particularly during charging or discharging of the traction battery. This expansion is also known as "swelling." To counteract this expansion, the battery cell assembly is mechanically tensioned. This is achieved by applying a tensioning force to the assembly using a tensioning band, thereby exerting a pressure that counteracts the expansion. The tensioning force thus counteracts the expansion force exerted on the tensioning band by the expanding battery cell assembly.

[0017] Before the clamping band is fixed to the battery cell assembly, the assembly is compressed. This means that, starting from its first outer circumference dimensions in its relaxed state, the assembly is compressed by applying a preload force to second outer circumference dimensions that are smaller than the first. The dimensions of the battery cell assembly are thus reduced in at least one direction by compression, particularly in an imaginary plane. Preferably, the clamping band is arranged around the compressed battery cell assembly with a preload; that is, the clamping band already has a non-zero tension when its clamping sections are fixed in the mounting recess by means of the fixing means.

[0018] After fixing the tension band sections in the mounting recess using the fixing agent, the battery cell assembly is released. During this process, the outer circumference dimensions of the battery cell assembly increase from the second outer circumference measurement towards the first. Specifically, the tension band is dimensioned, or its pretension is selected, such that it further compresses the battery cell assembly after release, resulting in smaller outer circumference dimensions after the tension band is applied and the assembly is released than the outer circumference dimensions of the fully released battery cell assembly before compression.

[0019] A plastic or a fiber-reinforced composite material with a plastic matrix is ​​used as the fixing agent. Preferably, the fixing agent is introduced into the mounting recess in a molten state and cooled there, allowing it to harden. Polyethylene, polypropylene, or polyamide are particularly suitable as the plastic. The fiber-reinforced composite material or the fiber-reinforced plastic comprises a plastic matrix and reinforcing fibers. The plastic matrix consists, for example, of polyethylene, polypropylene, or polyamide, or at least predominantly of these materials, i.e., at least 50%, 70%, or 90% by weight. The reinforcing fibers are, for example, glass fibers, carbon fibers, or the like.

[0020] A further development of the invention provides that the mounting recess is bounded by spaced-apart clamping edges, and that one of the clamping band sections is applied to each of the clamping edges, so that the clamping band sections between them contain a space that at least partially forms the mounting recess. The clamping edges bound the mounting 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. They preferably run parallel to each other.

[0021] One of the tension band sections is placed against each of the tension edges, with the distance between the tension edges being greater than the combined material thickness of the tension band sections. This ensures that, after the tension band sections are placed against the tension edges, they are spaced apart and occupy the gap between them. This gap forms at least part of the mounting recess. After the tension band sections are placed against the tension edges, the tension band or the surrounding area, particularly the tension edges, is heated. This heating process, for example, creates a material bond between the tension band sections and the respective tension edges to which they are attached.

[0022] In particular, the heating process involves heating the tension band to a temperature at which it at least partially melts, especially the plastic matrix of the tension band. After heating, the fixing agent is preferably applied directly into the mounting recess and thus into the gap, i.e., before the tension band or the assembly area cools down again. This results in a particularly reliable connection between the tension band and the assembly or the element arrangement.

[0023] A further development of the invention provides that the tensioning edges are arranged at an angle to a principal extension direction of the tensioning band. The principal extension direction of the tensioning band is understood to be the direction in which the tensioning band has its greatest dimensions, in particular its longitudinal direction. Specifically, the principal extension direction is perpendicular to any direction in which the material thickness of the tensioning band is present, as well as perpendicular to any direction in which the width of the tensioning band is present. The principal extension direction of the tensioning 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 oriented such that the clamping band sections in contact with them are deflected. This design enables particularly reliable fixing of the clamping band sections and / or the clamping band to grip the device or the element arrangement in different planes.

[0025] A further development of the invention provides that a multi-layered tension band and / or a tension band made of fiber-reinforced composite material is used as the tension band. The multi-layered tension band has several layers arranged one above the other, in particular abutting each other. Preferably, the tension band has the multiple layers in each of the tension band areas, which are each jointly applied to the tensioning edges of the fastening recess. By using the multi-layered tension band, the tension force achieved with the tension band can be significantly increased.

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

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

[0028] A further development of the invention provides that a heating fluid is introduced into the mounting recess by means of the heating device and / or a heating element of the heating device is applied to the device to heat the tension band and / or the device area. This heating can be carried out in different ways. Firstly, the heating fluid can be dispensed from the heating device in such a way that it flows onto and / or over the tension band and / or the device area. The heating fluid is, in particular, air. Before being dispensed, it is heated to a temperature sufficient for heating the tension band or the device area. The heat required for heating is transferred convectively.

[0029] Alternatively, or additionally, a heating element can be attached to the device so that the tensioning band or the device area is heated. The heating element is preferably designed such that it rests against the tensioning band or the device area at least along an imaginary line, or preferably over its entire surface. For example, the heating element rests against the tensioning band over its entire surface, so that the band is held clamped between the heating element and the device area, in particular the respective tensioning edge. For this purpose, the heating element is preferably shaped to fit the tensioning band so that it rests against the band not only along an imaginary line, but rather over a surface. The heat required for heating is transferred conductively by means of the heating element.

[0030] For example, it is possible to apply heat to the tensioning band or the area being fitted both convectively and conductively. This can involve first directing the heating fluid onto the tensioning band or the area being fitted while the heating element is kept at a distance, and then bringing the heating element into contact with it. This procedure ensures that the tensioning band or the area being fitted is heated reliably.

[0031] The invention provides that the fixing agent is introduced into the fastening recess by means of a heating device positioned against the tension band and / or the mounting area. The heating device is arranged such that, in cross-section, it overlaps the fastening recess, particularly the space between the tension band sections, and preferably completely, so that the space is closed by the heating device in cross-section. For example, in longitudinal section, the heating device largely closes the fastening recess, particularly to at least 80%, at least 90%, or even completely. This results in a particularly uniform distribution of the fixing agent within the fastening recess.

[0032] A particularly preferred embodiment of the heating device is one in which it is also used to introduce the fixing agent into the mounting recess. In this case, the heating device serves not only to heat the tensioning band or the assembly area, but also to secure the tensioning band sections in the mounting recess by introducing the fixing agent. This results in a particularly efficient fixing of the tensioning band to the tensioned assembly or the element arrangement of the assembly.

[0033] A further development of the invention provides that the heating device is arranged such that it completely overlaps the mounting recess in cross-section, in particular bearing against the tension band on opposite sides of the mounting recess. Such a design of the heating device has already been mentioned. It serves, firstly, to heat the tension band or the mounting area uniformly and completely, and secondly, preferably also to hold the fixing element inserted into the mounting recess in place.

[0034] A further development of the invention provides that heating is achieved by supplying hot fixing agent to the heating device. The fixing agent thus serves not only to permanently fix the tension band in the mounting recess, but also to heat the tension band and / or the mounting area, particularly without coming into direct contact with them. Preferably, the hot fixing agent is supplied to the heating device in such a way that it does not enter the mounting recess during heating, but remains within the heating device to heat it and thus also the tension band and / or the mounting area. Only after sufficient heating, for example to a specific temperature, is the fixing agent introduced into the mounting recess, for example by means of the heating device. This results in a particularly high efficiency of the described method.

[0035] The invention further relates to a manufacturing device for producing a device tensioned with a tension band, in particular for carrying out the method as described in this description, wherein the manufacturing device is designed and configured to arrange spaced-apart tension band sections of the tension band in a mounting recess of the device and to insert a fixing means into the mounting recess to secure the tension band sections in the mounting recess. The manufacturing device is further designed and configured to heat the tension band and / or a device section of the device bounding the mounting recess by means of a heating device before the fixing means is inserted into the mounting recess.

[0036] The advantages of such a design of the manufacturing device and such a procedure have already been mentioned. Both the manufacturing device and the method for operating it can be further developed as described in this document, and reference is made to these details.

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

[0038] The cover element partially, and preferably completely, covers the mounting recess while the fixing agent is being applied. This ensures a particularly uniform distribution of the fixing agent within the mounting recess. Furthermore, the cover element separates the fixing agent from the external environment, providing a degree of insulation and slowing down its cooling. The insulating element serves to thermally insulate the mounting recess. It may be in the form of the cover element or be integrated with it. This 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 tempered after being inserted into the mounting recess. For example, a specific temperature of the temperature control element is set, particularly according to a temperature profile over time. This allows the solidification of the fixing agent to be controlled. The temperature control element can be integrated with the insulating element and / or the cover element. Additionally or alternatively, the manufacturing device includes a sensor device. The sensor device records at least one measured value, at least intermittently. For example, the sensor device has a temperature sensor, so the measured value is the temperature. Using this measured value, the heating of the tensioning band or the assembly area and / or the cooling of the fixing agent can be monitored.The measures mentioned above 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. In this respect, the heating device is extremely temperature-resistant and also has good thermal conductivity. Preferably, the heating device has a metal base body covered with polytetrafluoroethylene and / or polyetheretherketone. This results in a particularly uniform temperature distribution during heating.

[0041] The features and combinations of features described in the description, in particular those described in the following figure description and / or shown in the figures, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention. Thus, embodiments 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, are also to be considered as encompassed by the invention.

[0042] The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without limiting the invention. The drawing shows: Fig. 1 a schematic representation of a device tensioned with a tension band, Fig. 2. A schematic detailed representation of an area of ​​the facility as well as a part of a manufacturing device for manufacturing the facility, and Fig. 3 a schematic sectional view of an area of ​​the facility as well as an area of ​​the manufacturing device.

[0043] The Fig. Figure 1 shows a schematic representation of a device 1 in the form of a battery cell arrangement, which is tensioned by a tension band 2. The device has an element arrangement 3, which is composed of several elements 4, of which only some are illustrated by way of example. In the present embodiment, the first of the elements 4 are configured 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 abutting one another and are jointly encompassed by the tension band 2. In particular, the tension band 2 rests against one of the end plates 6 with a continuously closed section, whereas it rests against the other end plate 6 with separate tension band sections 8 and 9. The path of the tension band 2 is indicated by way of example by means of arrows 10.

[0044] In one of the end plates 6, a mounting recess 11 is provided into which the tension band sections 8 and 9 engage. Specifically, the tension band sections 8 and 9 abut opposite tension edges 12 and 13, which define the mounting recess 11 on opposite sides. In the illustrated embodiment, the tension edges 12 and 13 are angled relative to a principal extension direction of the tension band 2, indicated by arrows 10. This angle deflects the tension band 2, or rather the tension band sections 8 and 9, so that the tension band, as indicated by arrows 14, encompasses the element arrangement 3 in an additional plane.

[0045] Preferably, the tension band 2 is divided into two sections by the deflecting effect of the fastening recess 11 or the tensioning edges 12 and 13. These sections at least partially, and preferably completely, encircle the element arrangement 3 in different planes. Preferably, the planes are angled relative to each other, thus forming an angle greater than 0° and less than 180°. For example, the angle is 90°, so that the sections of the tension band 2 encircle the element arrangement 3 in different directions or grip it on different sides.

[0046] The Fig. Figure 2 shows a schematic representation of the device 1 with the tension 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 tension band 2 and / or a device area 17, in particular comprising the tension edges 12 and 13, is heated, namely before a fixing means is introduced into the fastening recess 11 for fixing the tension band 2 or the tension band areas 8 and 9 in the fastening recess 11.

[0047] The heating device 16 is preferably designed to perform heating convectively and / or conductively. In particular, it completely overlaps the mounting recess 11 in cross-section, thus resting against the clamping band areas 8 and 9 on opposite sides of the mounting recess 11. On its side facing the device 1, the heating device 16 is shaped to fit the clamping band areas 8 and 9 so that it rests against them over a flat surface. For example, the heating device 16 is provided with a radius 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 towards the clamping band areas 8 and 9 through corresponding outlet openings 19 (not shown here).Preferably, the heating device 16 is designed to introduce the fixing agent 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 is evident that an air supply 20 is present, to which outlet channels 21 are fluidically connected. These outlet channels are angled relative to the air supply 20 and inclined towards 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 against the clamping band areas 8 and 9 or the clamping edges 12 and 13 outside the mounting recess 11, thus completely overlapping, and in particular closing, the mounting recess 11 in cross-section. Furthermore, it extends into the mounting recess 11, for example, by at least 50%, at least 60%, or at least 70% of the walls of the element 4 on which the clamping edges 12 and 13 are located. For this purpose, the heating device 16 is designed in a piston-like shape.

[0049] The described design of the device 1 or the manufacturing apparatus 15 enables a particularly efficient clamping of the device 1 with the tension band 2. In particular, it is possible to attach a multi-layered tension band 2 to the device 1 or its element arrangement 3 with particular reliability. REFERENCE MARK LIST: 1.
