Abstract
Description
[Technical Field]
[0001] explanation The present invention relates to a holding device for holding a magnetizable substrate during processing of at least one substrate surface thereof, and to a system and method for transporting and / or processing multiple substrates. [Background technology]
[0002] In particular, in the machining of delicate precision tools, such as workpieces formed in the form of small tools, cutting tools, punching tools, and embossing tools, transport and holding operations account for a significant portion of the overall work involved in the machining process. In machining processes such as coating processes for tool surface treatment, the tools to be machined are individually packaged at the customer's premises and shipped to the corresponding machining center before machining. These tools are then processed in various steps within the machining center, such as being unpacked, cleaned, coated, and blown with air, and then individually packaged again for shipping to the customer. This individual packaging is necessary to protect the tools from damage. Performing all of these individual operational steps results in a significant increase in the time consumed and, at the same time, a high risk of individual tool damage. Furthermore, consistent tool quality cannot be guaranteed. When machining particularly delicate precision parts, the operating effort and the associated risk of damage are particularly high. Summary of the Invention [Problem to be solved by the invention]
[0003] It is therefore an object of the present invention to at least partially overcome the above-mentioned drawbacks of known holding devices for holding magnetizable substrates and systems for transporting and / or machining a plurality of substrates, in particular a plurality of workpieces or tools to be machined. In particular, it is an object of the present invention to provide an apparatus and a system which allows stable fixation of the substrates during transport and / or machining in a simple and cost-effective manner, thereby minimizing the operating effort required to machine a plurality of substrates. Additionally, it is an object of the present invention to ensure a particularly accurate positioning of the plurality of substrates during processing, thereby enabling particularly accurate processing of the plurality of substrates. [Means for solving the problem]
[0004] The above-mentioned object is solved by a holding device for holding a substrate, having the device features set forth in the independent claims, a system for transporting and / or processing a plurality of substrates, having the system features set forth in the independent claims, and a method for transporting and / or processing a plurality of substrates, having the method features set forth in the independent claims. Further features and details of the invention can be taken from the respective dependent claims, the following description and the accompanying drawings. Features and details set forth with respect to the holding device according to the invention naturally also apply with respect to the system according to the invention and the method according to the invention, and vice versa, respectively, so that individual aspects of the invention are or can always be cross-referenced with each other in the context of the disclosure.
[0005] According to the present invention, there is provided a holding device for holding a magnetizable substrate during processing of at least one substrate surface, in particular for holding a magnetizable workpiece or tool to be processed. The holding device includes a magnetic holding unit arranged at an end and for fixing the substrate at the end by generating a magnetic field, a receiving unit arranged on the holding unit for receiving the substrate, and an exchangeable adapter unit arranged in the receiving unit for guiding and shielding the substrate. According to the present invention, the adapter unit has at least one recess for passing the substrate therethrough, so that the substrate can be fixed in the holding device in a manner supported laterally by the recess.
[0006] The holding device can be used both for transporting and for processing or machining the substrate or for processing at least one substrate surface. Such processing can be performed, for example, by polishing and / or chemically, and can include, in particular, cleaning, pre- and / or post-treatment of the substrate, as well as coating the substrate. It is understood that the magnetizable substrate can also be formed to be only partially magnetizable, i.e., have magnetizable components, such as, for example, a magnetizable holding handle or a partially magnetizable holding handle. The magnetizable substrate can also be formed, in particular, in the form of a magnetizable workpiece or a magnetizable tool. In particular, precision tools that are prone to breakage, such as shaft tools or punching tools, especially small punches, cutting punches, blanking punches, embossing punches, or forming punches, can be considered as viable tools. The holding device according to the invention is specifically designed / configured to hold only a single substrate. This allows maximum flexibility in the selection of processing methods, for example, allowing two-dimensional and even three-dimensional rotation during machining processes, such as coating. Magnetic fixation can advantageously be achieved by bringing the holding device into contact with the edge face of a magnetizable substrate, preferably with the edge face of a magnetizable tool to be machined. In addition to guiding the substrates laterally, the holding device, in particular the adapter unit, serves to shield or conceal these substrates, in particular during surface treatment processes such as coating processes. It is particularly provided according to the invention that the same holding device can be used to process different substrates, in particular tools of different shapes, by simply changing or exchanging the adapter unit. The recess for guiding the substrate does not need to be designed / configured to precisely fit the substrate to be accommodated, and therefore does not need to be in full contact with the substrate during accommodation, but may only be in partial contact with the substrate.
[0007] It is recognized within the scope of the present invention that by using a holding device according to the present invention, manipulation of individual tools during transport and processing operations is completely eliminated, thereby significantly reducing the risk of damaging the substrate. In addition, by using a holding device according to the present invention, particularly accurate positioning of the substrate is possible, which in turn allows particularly accurate processing of the substrate. In addition, when using the holding device, in particular the exchangeable adapter unit according to the present invention, the number of required variations of the holding device is significantly reduced, since one and the same holding device can be made suitable for use with a large number of different substrates by simply changing or replacing the adapter unit.
[0008] In the case of a particularly compact configuration, and in order to ensure particularly uniform processing of the substrates, it may be advantageously provided that the receiving unit is shaped like a hollow cylinder and that the receiving unit is arranged with respect to the exchangeable adapter unit and the magnetic holding unit in such a way that the substrate can be centrally positioned within the receiving unit, with centrally positioned being understood in particular to mean an arrangement in which the substrate has at least substantially the same distance from the edge region of the receiving unit along its accommodation in the receiving unit.
[0009] With regard to ensuring processing of the substrate during pick-up, in particular with regard to particularly uniform processing of the substrate, it can be provided in an objectively advantageous manner that the pick-up unit has recesses for contacting the substrate, which recesses are preferably formed in the form of symmetrically arranged, in particular longitudinally arranged cutouts in the pick-up unit, in particular this allows for direct contact of, for example, cleaning liquids, drying air, coating agents, etc. with the substrate during processing.
[0010] With regard to the stable positioning of the substrate during processing, it can also be advantageously provided that the exchangeable adapter unit has at least one guide means / element for guiding the substrate, and that a recess for guiding the substrate is arranged in the guide element, preferably centrally arranged in the guide element. In this case, the recess can preferably be formed in the shape of a bore or the like and can be adapted in particular to the geometric shape of the substrate to be guided. In addition to guiding the substrate, the guide element can also serve to shield or conceal the substrate, for example during surface processing operations.
[0011] In situations of particularly simple exchange or particularly simple and rapid adaptation, it may also be advantageously provided that the guide element is formed in the form of a flat part, in particular in the form of a guide disk, which can then be specifically shaped to the substrate to be processed, in particular with regard to the recess, so that when changing to process a different substrate, only the guide element has to be exchanged and one and the same holding device can be used to transport and handle different substrates, for example different punching tools.
[0012] For a material-saving and lightweight design / construction, the guide elements can have a material thickness of less than 2 mm, preferably 1.5 to 1 mm. At material thicknesses of 1.5 to 1 mm, particularly good results can be achieved in terms of reliable and precise machining. On the other hand, at material thicknesses below 1 mm, there is a risk that thermal effects will adversely affect the material.
[0013] In situations where a particularly stable positioning of the substrate during processing is required, it can further be envisaged that the exchangeable adapter unit comprises at least a second guide element for guiding the substrate, the second guide element preferably comprising a centrally arranged recess for the passage of the substrate, the recess being particularly centrally arranged in the guide element.
[0014] In order to allow both stable guidance and easy insertion of the substrate into the holding device, it may be provided here in particular that the second guide element is arranged at a distance from the first guide element and in particular matingly arranged with the first guide element. In the context of the present invention, mating is understood to mean in particular an arrangement in which two, preferably centrally arranged, recesses for the passage of the substrate are arranged one above the other in a snug fit.
[0015] With regard to maximizing stabilization, it is further conceivable according to the invention for the exchangeable adapter unit to comprise three or more guide elements, in particular four or more guide elements, for guiding the substrate.
[0016] To ensure optimal positioning of one or more guide elements, it can be advantageously provided according to the invention that the exchangeable adapter unit has spacing means / elements for spacing the guide elements, which spacing elements are preferably arranged directly on the guide elements, in particular directly between the first and second guide elements. In the context of the invention, directly arranged is understood to mean in particular an arrangement in which the spacing elements abut the guide elements. Preferably, the guide elements can rest at least partially on the spacing elements.
[0017] To ensure a simple, cost-effective, and flexible connection between one or more guide elements and the spacing element, the guide elements can preferably be connected to the spacing element by a force fit, for example by means of latching hooks, latching lugs, or connecting lugs. For example, a three-part configuration may be provided in which the guide elements are force-fitted onto the spacing element. Within the scope of a stable arrangement, the guide elements can alternatively be connected to one another in a material-to-material manner, for example by an arc welding process (e.g., a TIG welding process) or a beam welding process (e.g., a laser welding process).
[0018] With regard to the processing of the substrate during pick-up, in particular to ensure a particularly uniform processing of the substrate during pick-up, it can be provided in an objectively advantageous manner that the spacing elements have recesses for contacting the substrate, which recesses are preferably arranged symmetrically in the pick-up unit and are in particular formed in the form of cutouts arranged on the longitudinal sides, which in particular allow for direct contact of, for example, cleaning liquids, drying air, coating agents, etc. with the substrate during processing.
[0019] In circumstances that ensure a particularly compact arrangement and particularly uniform processing of the substrate, it can be provided in an objectively advantageous manner that the intervals are shaped like hollow cylinders and are arranged symmetrically within the storage unit, preferably in the storage unit so that the recesses of the intervals overlap at least partially, in particular completely, with the recesses of the storage unit.
[0020] Within the scope of the structurally simple fixing of the spacing means / elements or guide elements to the receiving unit according to the invention, it can be advantageously provided that the adapter unit has fixing means / elements for fixing the adapter unit in the receiving unit, the fixing elements being preferably formed in the form of spring elements, in particular in the form of clamping rings, which here are preferably arranged above one or more guide elements, in particular directly above the first guide element.
[0021] It may also be provided that the magnetic holding unit has a magnet, e.g., a permanent magnet, which is preferably completely enclosed in the holding unit, within the scope of a simple structural guarantee of the magnetic holding force, and which is formed in the form of a heat-resistant magnet, particularly preferably a heat-resistant magnet for temperatures above 450°C. 17SmCo magnets of this type are feasible magnets for this purpose. In the context of the present invention, encapsulation is understood to mean, in particular, complete enclosing. In this context, the magnet is preferably cylindrical and may have a diameter of less than 20 mm, preferably less than 15 mm, in particular less than 10 mm. The encapsulation ensures that the magnetic force only serves to fix the magnet, thereby eliminating any adverse effects on the processing operations to be performed, such as coating operations, in particular plasma coating operations. In combination with a corresponding encapsulation, a suitable magnet offers the particular advantage of ensuring reliable fixation while reducing the effects on the processing operations to be performed.
[0022] To achieve a structurally simple magnetic shielding, it may be provided that the magnet is arranged in the holding unit such that a holding unit with a material thickness of at least 0.5 mm is arranged between the magnet and the receiving unit arranged directly on the holding unit. This particularly ensures that direct contact between the magnet and the substrate is prevented. The magnet can be preferably pressed into the holding unit by a locking bolt or the like.
[0023] In an advantageous embodiment, the present invention provides a protective cover for protecting a substrate that can be placed in a holding device, particularly during transport, to the extent that protection of the substrate placed in the holding device can be ensured cost-effectively and structurally simply. The protective cover has an opening through which the protective cover can be fastened to the receiving unit, preferably at its edge, and in particular can be fastened tightly and / or loosely to the receiving unit. In this case, the protective cover can preferably be in the form of a protective cap or a transport cap, etc., and can in particular be designed / configured as a rotating part. In particular, the protective cover can be manufactured so that it can be fastened to the receiving unit with a tolerance of 0.3 mm.
[0024] Similarly, with regard to ensuring accurate placement of the substrate within the holding device, the protective cover may include a second opening for detecting the orientation of the disposable substrate within the holding device, the second opening preferably being located opposite the first opening.
[0025] Within the scope of a cost-effective design / construction, it is particularly conceivable here for the protective cover to be at least partially, preferably completely, made of plastic, in particular in the form of polyethylene and / or polyvinyl chloride and / or polyethylene terephthalate and / or polystyrene. It is understood that in addition to the plastics mentioned above, similar plastics with comparable properties can also be used.
[0026] It is also an object of the present invention to provide a system for transporting and / or processing a plurality of substrates, wherein the system according to the present invention comprises a plurality of holding devices as described above for holding the substrates and a holding unit for holding the holding devices. According to the present invention, the plurality of holding devices are arranged in the storage unit such that, if the substrates are stored separately, the stored plurality of substrates can be transported and / or processed together in the holding devices. Thus, the system according to the present invention has the same advantages as those already described in detail for the holding devices according to the present invention.
[0027] Within the scope of the structurally simple design / configuration of the system, it is particularly conceivable that the holding unit is formed in the form of a basket with a plurality of holding devices for holding said plurality of holding devices, which holding devices are preferably fastened in the holding elements in a form-fitting and / or force-fit manner.
