Description

[0001] Curing and / or bonding device

[0002] SPECIFICATION

[0003] The present claimed subject matter is direct to a curing and / or bonding device for curing and / or bonding a product, in particular plate shaped components, for example graphite bipolar plates. The product might comprise expandable graphite. For example for the production of a product, like a bipolar plate, in particular graphite bipolar plate (gBBP) from expanded graphite, individual plates or web-shaped goods are calendered and embossed with a structure, for example the structure of a bipolar single plate. After embossing, the product, for example the individual plate, is impregnated, washed and cured.

[0004] In the prior art different curing devices have been proposed.

[0005] For example, CN 102 208 659 A describes a curing device in form of a curing oven. A plurality of bipolar plates is combined into a batch and the batch is positioned within a heating department of the oven. This leads to a complex handling of the plate shaped components decreasing the efficiency of the production process.

[0006] In alternative previous known curing processes, impregnated individual plates are heated and cured in a flat press. This process is anyhow also not transferable on a continuous path.

[0007] Furthermore CN 114 725 417 A proposes a continuously working curing device. The curing leads however to a so-called foaming, i.e. fluids within the plate expand and lead to an expansion of the component. It is thus necessary to carry out a separate compression step after the curing. Also, this additional step leads to a decrease in the production efficiency. To overcome the foaming problem it is proposed in CN 114 801 266 A to use a water bath into which the component is dipped. This type of curing can cause the plates to warp slightly so that the required flatness is no longer present.

[0008] It is thus the object of the claimed subject matter to further develop the curing devices known in the prior art, in particular to allow an efficient production process of a product with a constant high quality of the end product.

[0009] This object is achieved by a curing and / or bonding device for curing and / or bonding at least one product, in particular a component of an energy storing, energy converting and / or energy producing element, the device comprising at least one transport element and at least one temperature control device, wherein the product is moved by the transport element relative to the temperature control device, wherein the transport element comprises at least one first conveyor belt and at least one second conveyor belt, and wherein further an accommodation area is formed between the first conveyor belt and the second conveyor belt and the at least one product is sandwiched between the first conveyor belt and the second conveyor belt in the first accommodation area.

[0015] Furthermore, a device can be characterized in that the first heating component comprises at least two, preferably a plurality of, first heating elements and / or the second heating component comprises at least two, preferably a plurality of, second heating elements.

[0016] Alternatively or additionally, it is proposed that at least one first heating element and at least one second heating element, preferably at least a pair and / or plurality of first heating elements and second heating elements, are arranged opposite to each other, in particular aligned along the accommodation area and / or along the direction of movement of the first conveyor belt and / or the second conveyor belt, in particular in the accommodation area.

[0017] In particular for the two before described embodiments it is proposed that at least two of the first heating elements and / or of the second heating elements are configured to be heated to different temperatures, in particular to provide different hearting zones within the accommodation area. Furthermore, it is preferred that the number of first heating elements and of second heating elements is different, in particular the number of first heating elements is lower compared to the number of second heating elements.

[0018] It is also proposed that an extension of the first conveyor belt along a direction of movement of the first conveyor belt and the second conveyor belt is smaller compared to an extension of the second conveyor belt along said direction, wherein optionally the second heating component and / or at least one second heating element is / are located at least partly outside the accommodation area, in particular in a section of the second conveyor belt extending beyond the first conveyor belt.

[0020] Furthermore, it is proposed that the device comprises at least one actuator device for driving the first conveyor belt and / or the second conveyor belt.

[0021] For the before described embodiment it is proposed that the actuator device comprising at least one first actuator element for driving the first conveyor belt and at least one second actuator element for driving the second conveyor belt.

[0022] Furthermore, it is proposed that the first actuator element and the second actuator element are mechanically separated from each other and / or are configured to ensure the same speed of the first conveyor belt and the second conveyor belt, in particular are, optionally electrically, synchronized and / or controlled. Alternatively or additionally it is proposed that the first actuator element is mechanically connected to the second actuator element via at least one connection element, wherein the connection element optionally comprises at least one chain, at least one belt, at least one shaft, and / or at least one gear, wherein optionally the connection element is configured to ensure the same speed of the first conveyor belt and the second conveyor belt and / or the first actuator element and the second actuator element.

[0023] The device can be characterized in that the first actuator element comprises at least one first drive element and / or the second actuator element comprises at least one second drive element, wherein the first drive element and / or the second drive element comprises at least one electrical, at least one magnetic, at least one electromagnetic, at least one pneumatic, and / or at least one hydraulic drive component.

[0024] Furthermore, embodiments can be characterized in that the distance between the first conveyor belt and the second conveyor belt and / or the height of the first accommodation area decreases along the direction of movement of the product and / or the direction of movement of the first conveyor belt and / or the second conveyor belt in the accommodation area.

[0025] It is also proposed that the first conveyor belt and / or the second conveyor belt comprise(s)

[0026] - at least one Polyphenylene sulfide (PPS) material, at least one carbon fiber material, at least one glass fiber material, at least one metal web, at least one Polytetrafluoroethylene, PTFE, material, at least one Polytetrafluoroethylene coating and / or at least one coating comprising at least one fluorinated material;

[0027] - a temperature resistance of 250°C. 400°C , and / or 600°C, and / or

[0028] - a mesh material, preferably comprising a mesh density of 2 to 110, 90 to 210, 190 to 410, 390 to 610, 590 to 810, and / or 790 to 1000 lines per cm.

[0029] Finally it is proposed that the product comprises at least one energy storing element, at least one energy producing element, at least one energy converting device, at least one battery component, at least one fuel cell component, at least one electrolyzer, at least one plate shaped component, at least one separated plate shaped component, a plurality of plate shaped components, at least one bipolar plate, at least one graphite bipolar plate, at least one continuous product, at least one web shaped material, at least one multilayer component, wherein optionally the layers are adhered to each other, preferably using at least one adhesive, and / or heat bonding.

[0030] Thus, the claimed subject matter is based on the astonishing perception that a curing device for curing a product like a plate shaped component, can be provided that allows an efficient production process, in particular allows an integration into an automated, continuous production process and allowing a higher quality of the final product compared to known curing devices in that the curing device comprises conveyor belts forming an accommodation area through which the product is conveyed.

[0031] This configuration allows to locate heating components on both sides of the product to allow an efficient curing of the product with a simultaneous confinement of the product by exercising a defined contact force of the conveyor belts onto the product. This gives the opportunity to force an / or press the product into the desired thickness and / or to hold the thickness of the product constant over the curing process. In particular compared to curing devices using a water bath for the hardening process, the use of such a belt furnace allows to prevent warping and / or swelling of the product. Furthermore, this configuration allows the hardening of products in form of individual components and / or plates as well as of webshaped material.

[0032] Preferably the contact force acting on the product by the conveyor belt(s) and the distance between the conveyor belts and thus the thickness of the accommodation area can be adjusted.

[0033] By providing conveyor belts that are at least partly (semi-)permeable for fluids the efficient removal of resulting gases and fluids during curing can be ensured. For example, at least one, preferably both conveyor belts are open pore and / or porous, so that the fluid produced during curing can escape away from the product through the conveyor belt(s).

[0034] To ensure a continuous high quality of the curing, in particular a defined heat transport to and / or from the product is proposed that the curing device comprises at least one cleaning device. The cleaning device allows to remove contaminations on the conveyor belts. Such contaminations might result from fluids, like gases, escaping from the product during the curing process. This fluid contains decomposition products, for example of an impregnating agent. The contaminations, like degradation products, settle in the conveyor belts and contaminate or clog them.

[0035] In order to ensure continuous operation at a constant high quality the, in particular integrated, cleaning device allows a removal of these contaminations ensuring for example that all fluids escaping from the product can be efficiently exit the accommodation area and the curing device. The cleaning can be accomplished by a pyrolytic cleaning, wherein the heat energy is preferably provided by the temperature control device. In this case the cleaning device at least partly includes the temperature control device and / or is at least partly comprised by the temperature control device. Additionally or alternatively the cleaning device might comprise at least one washing and / or or rubbing unit for the conveyor belts to remove the contaminations.

[0036] To reduce shear forces acting on the product that might reduce the product quality and constant geometry and / or form of the product it is preferred that the conveyor belts move with the same speed. Such a synchronized movement can be reached by two separated actuation devices, for example drive elements in form of two separated direct drives. By synchronization of these drive elements the same movement speed of the conveyor belts can be ensured. Alternatively, both belts and / or respective actuator elements are connected by means of a mechanical connection element, e.g. a chain and / or a, preferably toothed, belt so that only one drive element is required and the synchronization is ensured by the mechanical connection element.

[0037] It is preferred that the heating components comprise different separate heating elements that are separately controllable. This allows to define separate heating zones having different temperatures to provide a heating profile over the length of the device, in particular over the extension and / or length of the conveyor belts. For example the temperatures of a chain of second heating elements, in particular located at a second, optional lower, conveyor belt along the second conveyor belt might be 70°C to 90°C, preferably 80°C for a first second heating element, followed by a second second heating element having a temperature of 110°C to 140°C, preferably 120°C to 130°C, preferably 135°, followed by a third second heating element having a temperature of 150°C to 170°C, preferably 160°C. Also, respective first heating elements located at the first conveyor belt might have complementary temperatures. Also, it is possible that the number of first heating elements is different from the number of second heating elements, for example when the first, for example upper conveyor belt, has a reduced extension compared to the second, for example lower, conveyor belt. This allows to form a loading area for the product to be cured and / or bonded. It also provides further space in the area of, in particular underneath, the (second) conveyor belt to position a (second) heating element, optionally used as a preheating element for the product before entering the accommodation area.

[0038] Also, a pair of first and second heating elements might have the same temperature to form the temperature profile.

[0039] This allows to provide defined heating zones, for example heating zones spanning a temperature range from 80°C to 200°C.

[0040] To ensure a defined cooling of the product it is possible that the temperature control device comprises a cooling element, for example located at the outlet of the device and / or following the end of the first heating component and / or the second heating component. By providing this defined cooling zone, an unwanted deformation of the product due to internal temperatures stresses can be avoided, at least reduced.

[0041] In case the second conveyor belt forms a lower conveyor belt in the use configuration of the device and the length and / or extension of the second conveyor belt is greater than the length and / or the extension of the first, upper conveyor belt, individual products can be placed on the lower conveyor belt outside the accommodation area and / or removed form the lower conveyor belt outside the accommodation area.

[0042] The use of the device is not restricted to the curing of a product. It can also be used to bond subproducts to a final product, for example two plates to form bipolar plates. An adhesive, like glue, is applied to the subproducts outside the device and the subproducts, like plates, are joined together to form the product, for example a bipolar plate. To cure the adhesive, the combined subproducts, like a bipolar plate, are placed on the second conveyor belts, like a lower conveyor belt, and passed through the accommodation area. The parameters (e.g. temperature, conveyor belt speed, contact pressure, and / or thickness of the accommodation area) may differ from the parameters during hardening.

[0043] Further features and advantages of the claimed subject matter will become apparent from the following description of an embodiment of the claimed subject matter with the help of the enclosed figure, wherein

[0044] Fig. 1 shows a schematic cross sectional view of an embodiment of a curing and / or bonding device.

[0045] Figure 1 shows a curing and / or bonding device 1. By the device 1 a product 3 can be cured. In the shown example the product 3 is a plate shaped component of a battery, in particular a single bipolar plate. For the curing process the product 3 is located within an accommodation area 5. The accommodation area 5 is formed between a first, upper, conveyor belt 7, and a second, lower conveyor belt 9. The conveyor belts 7, 9 transport the product 3 through the accommodation area 5.

[0046] The second conveyor belt 9 is extended compared to the first conveyor belt 7 to form a loading area 11 and an unloading area 13, respectively so that individual products 3, in particular plate shaped components, can be placed on and removed from the second conveyor belt 9.

[0047] A distance A between the first conveyor belt 7 and the second conveyor belt 9 represents a first value and defines a thickness and / or height of the accommodation area 5. By a height adjustment device 15 the first value A can be adjusted so that the gap A between the conveyor belts 7, 9 can be adjusted. Preferably the distance A is adjusted to the thickness of the products 3, optionally a target thickness and / or an actual thickness of the product 3 when entered into the accommodation area 5. This allows to simultaneously carry out a pressing of the product 3 during the curing process. For this purpose, the height adjustment device 15 forces the first conveyor belt 7 into the direction of the second conveyor belt 9, in particular with a force F.

[0048] The height adjustment device 15 is connected to first actuator elements 17 in form of drive pullies. In the device 1 at least one of the first actuator elements 17 is driven by an, optionally electric, drive element. By a connection element 19 of the height adjustment device 15 the actuator elements 17 and thus the first conveyor belt 7 are forced into the direction of the second conveyor belt 9.

[0049] Also, the second conveyor belt 9 is driven. The driving is accomplished by second actuator elements 21 in form of drive pullies. The second actuator elements 21 are driven by a separate drive element. The drive elements of the first conveyor belt 7, in particular the first actuator elements 17, and the second conveyor belt 9, in particular the second actuator elements 21, are synchronized so that the drive speed of the conveyor belts 7, 9 are identical, in particular the rotational speeds of the first actuator elements 17 and second actuator elements 21 in the directions 23, 25 are identical in case the drive pullies 17, 19 have the same diameter.

[0050] The device 1 furthermore comprises a temperature control device 27 having a first heating component 29 and a second heating component 31. The first heating component 29 is also connected to the connection element 19 of the height adjustment device 15, whereas the second heating component 31 is connected to a support structure also supporting the second actuator elements 21. In this way the second heating component 31 acts as a mechanical support surface for the second conveyor belt 9 as being in direct contact with the conveyor belt 9. This direct contact also increases the heat transfer from the second heating element via the conveyor belt 9 into the product 3.

[0051] The pressing force onto the product 3 is build up by the conveyor belt 7 being in direct contact with the product 3. Due to the gravitational force the conveyor belt 7 is in direct contact with the product 3 and the force f is transferred to the conveyor belt 7 via the connection element 19 and the drive pullies 17 as well as the tension of the belt 7. To ensure a best possible heat energy transfer the first heating component is located as close as possible to the conveyor belt 7 with a minimal gap therebetween.

[0052] To allow the formation of different temperature, heating and / or curing zones each of the heating components 29, 31 comprises a plurality of heating elements. In this embodiment the first heating component 29 comprises four first heating elements 33a, 33b, 33c, 33d, whereas the second heating component 31 comprises six second heating elements 35a, 35b, 35c, 35d, 35e, 35f. The heating elements 33a, 35a, , the heating elements 33b, 35b, the heating elements 33c, 35c and the heating elements 33d, 35d form respective pairs being located opposite to each other. Preferably the respective pairs are heated to a similar or identical temperature to form a heating zone with a specific temperature. Due to the greater extension of the second conveyor belt 9 the space underneath the conveyor belt 9 is greater allowing to locate further heating elements 35e and 35f under the conveyor belt 9.

[0053] For example, the heating element 35e can be used to preheat the product 3 to a first temperature, for example 60°C before it enters the heating zone formed between the heating elements 33a, 35a building up a temperature of for example 80°C allowing a preconditioning of the product 3. The product 3 might remain for 15 seconds to 1 minute in this heating zone leading to a further preheating of the product to remove for example water included in the product 3.

[0054] The product 3 than enters the heating zone formed between the heating elements 33b, 35b building up a temperature of 120°C to 130°C in this part of the accommodation area 5 to further heat the product 3 before entering the heating zone formed between the heating elements 33c, 35c providing a temperature of for example 160°C for the curing to remove remaining process fluids, for example impregnation fluids. The further heating elements 33d, 35d, and 35f allow a defined cooling down of the product 3 before reaching the unloading area 13. During the complete curing process the product 3 is held in form by the conveyor belts 7, 9 and the forces build up by them to avoid any unwanted deformation of the product during the curing process.

[0055] To further define the cooling down procedure of the product 3 it is possible that instead of heating element 35f or in addition to the heating element 357 a cooling element is comprised by the heating component 31.

[0056] Thus the device provide several heating zones to control the heating and curing of the product 3. In addition, the heating zones can be used for subsequent outgassing.

[0057] Also the contact pressure of the upper belt 7 can be varied and the upper belt might be inclined relative to the second belt 9 to increase the pressure force over the length of the device 1.

[0058] For example the product 3 might have a retention time of 3 to 12 minutes within the accommodation zone 5 and the conveyor belts 7, 9 might move the product with a speed of 0,5m / min.

[0059] The features disclosed in the specification, the claims and the figure may be essential to the invention in its various embodiments, either individually or in any combination.
