HOLDING DEVICE FOR HOLDING A MAGNETIZABLE SUBSTRATE WHILE PROCESSING A SURFACE

OF THE SUBSTRATE

Description

The present invention relates to a holding device for holding a magnetizable substrate during processing of at least one substrate surface as well as a system and a method for transporting and / or processing a plurality of substrates.

In particular when processing sensitive precision tools, such as workpieces formed in the form of miniature, cutting, punching and embossing tools, the transport and holding processes take up an essential part of the overall effort involved

Machining process a. In machining processes for the surface treatment of tools, such as for example coating processes, the tools to be machined are commonly used before machining Customers individually packaged and sent to the appropriate machining centers. The tools are then treated in various steps in the machining center, for example unpacked, cleaned, coated, blasted and individually packaged again for shipping to the customer. The individual packaging is necessary to protect the tools from damage. All these individual handling steps result in a very large expenditure of time and at the same time a great risk of damage to individual tools. In addition, it is not possible to ensure a constant quality of the tools. The handling effort and the associated risk of damage are particularly great when machining filigree precision parts.

It is therefore the object of the present invention to at least partially remedy the aforementioned disadvantages of known holding devices for holding a magnetizable substrate and systems for transporting and / or processing substrates, in particular workpieces or tools to be processed. In particular, it is the object of the invention to provide a device and a system that allow a stable fixation of substrates in a simple and inexpensive manner during transport or processing and thus minimize the handling effort for processing the substrates. In addition, it is an object of the invention to ensure a particularly precise arrangement of the substrates during processing, which enables particularly precise processing of the substrates in question.

The above object is achieved by a holding device for holding a substrate with the features of the independent device claim, a system for transporting and / or processing a plurality of substrates with the features of the independent system claim and a method for transporting and / or processing a plurality on substrates with the features of the independent process claim. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the holding device according to the invention naturally also apply in connection with the system according to the invention and the method according to the invention and in each case vice versa, so that with regard to the Disclosure on the individual aspects of the invention is always referred to or can be mutually referred to.

According to the invention, a holding device is provided 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, which has a magnetic holding unit arranged at the end for fixing the substrate at the end via the formation of a magnetic field, one on the Holding unit arranged receiving unit for receiving the substrate as well as an interchangeable adapter unit arranged within the receiving unit for guiding and shielding the substrate comprises. According to the invention, the adapter unit has at least one recess for the passage of the substrate, the substrate being laterally supported within the holding device by means of the recess

The holding device in question can be used both for transporting and for treating or processing substrates or processing at least one substrate surface. The treatment can take place here, for example, abrasively and / or chemically and in particular include cleaning, pre- and / or post-treatment and coating of the substrates. It goes without saying that an objective magnetizable substrate can also be made only partially magnetizable, that is to say, for example, it can have a magnetizable component, such as a magnetizable handle or a partially magnetizable handle. The magnetizable substrate can also be formed in particular in the form of a magnetizable workpiece or a magnetizable tool. In particular, sensitive precision tools, such as shank tools or punching tools, in particular miniature, cutting, punching, stamping or forming punches come into consideration as possible tools. The holding device according to the invention is designed in particular to receive only a single substrate. This enables the greatest possible freedom with regard to the selection of machining processes and, for example, also allows two- and three-dimensional rotations during a machining process, such as during a coating or the like. Magnetic fixation can advantageously be achieved by contact of the holding device with an end face of a magnetizable substrate, preferably the end face side of a magnetizable substrate to be processed Tool. The holding device, in particular the adapter unit, serves not only to guide the substrates laterally, but also to shield them or mask them in surface treatment processes, such as coating processes, for example. According to the invention, it is provided in particular that the same holding device can be used for processing different substrates, in particular tools of different shapes, by merely modifying or replacing the adapter unit. The objective recess for guiding the substrates does not have to be designed precisely for a substrate to be picked up and therefore does not have to have full contact with the substrate in question while a substrate is being picked up, but can also only be partially in contact with the substrate.

In the context of the invention, it has been recognized that the use of a holding device according to the invention completely eliminates the need to handle individual tools during transport and processing operations and thus significantly reduces the risk of damage to the substrates. In addition, a particularly exact arrangement of the substrates is possible through the use of an objective holding device, which allows a particularly exact processing of the substrates. In addition, through the use of the objective holding device, in particular through the interchangeable adapter unit according to the invention, one and the same holding device is suitable for the use of a large number of different substrates by only modifying or replacing the adapter unit, which enormously reduces the necessary variety of objective holding devices.

As part of a particularly compact arrangement and ensuring particularly homogeneous processing of a substrate, it can advantageously be provided that the receiving unit is shaped as a hollow cylinder and is arranged in relation to the exchangeable adapter unit and the magnetic holding unit in such a way that a substrate can be arranged centrally within the receiving unit. In this context, a central arrangement is understood to mean in particular an arrangement in which the substrate along its receptacle within the receptacle unit has at least essentially the same distance from the edge regions of the receptacle unit. With regard to ensuring processing of a substrate during a recording, in particular with regard to particularly homogeneous processing of a substrate, it can advantageously be provided that the receiving unit has recesses for contacting the substrate, the recesses preferably being arranged symmetrically within the receiving unit , in particular in the form of cutouts arranged along the length. In particular, this allows direct contact to be made with the substrate during processing, for example by means of cleaning fluids, drying air, coating agents and the like.

With regard to a stable arrangement of a substrate during processing, it can objectively advantageously also be provided that the exchangeable adapter unit has at least one guide means for guiding the substrate, the recess for the implementation of the substrate being arranged within the guide means, the recess for the implementation of the Substrate is preferably arranged centrally within the guide means. The recess can preferably be in the form of a bore or the like and in particular be adapted to the geometry of the substrate to be guided. In addition to guiding a substrate, the guiding means can also serve to shield or mask the substrate, for example during a surface treatment process or the like.

In the context of a particularly simple exchange or a particularly simple and quick adaptation, it can also advantageously be provided that the guide means is in the form of a flat part, in particular in the form of a guide disk. The disk can be shaped specifically with regard to the recess on the substrates to be processed, so that when changing different substrates to be processed, only the guide means have to be exchanged and one and the same holding device can be used for transporting and handling different substrates, for example different punching tools .

Here, the guide means can have a low material thickness of less than 2 mm, preferably one, in terms of a light and material-saving design Have material thickness between 1.5 mm and 1 mm. With a material thickness between 1.5 mm and 1 mm, particularly good results in terms of reliable and precise machining could be achieved. A material thickness of less than 1 mm, on the other hand, harbors the risk of a negative influence on the material due to thermal effects.

In the context of a particularly stable arrangement of a substrate during processing, it is also conceivable that the exchangeable adapter unit has at least one second guide means for guiding the substrate, the second guiding means preferably having a centrally arranged recess for the passage of the substrate, which in particular is centrally located within the Guide means is arranged.

In order to enable both stable guidance and simple introduction of a substrate into the folding device, it can be provided that the second guide means is arranged spaced apart from the first guide means, in particular is arranged congruently to the first guide means. In the context of the invention, a congruent arrangement is understood to mean, in particular, an arrangement in which the two preferably centrally arranged recesses for the implementation of the substrate are arranged precisely one above the other.

With a view to maximizing stabilization, it is also conceivable according to the invention that the exchangeable adapter unit has more than two guide means, in particular more than three guide means for guiding the substrate.

In order to ensure optimal positioning of one or more guide means, it can advantageously be provided according to the invention that the exchangeable adapter unit has a distancing means for distancing the guide means, the distancing means preferably being arranged directly on the guide means, in particular directly between the first and second guide means. In the context of the invention, a direct arrangement is understood to mean, in particular, an arrangement in which the spacing means rests in contact with the guide means or the guide means. The guide means can preferably rest at least partially on the spacing means. To ensure a simple, inexpensive and flexible connection between one or more guide means and the spacing means in question, the guide means can preferably be connected to the spacing means via a form fit, for example via latching hooks, latching lugs or connecting tabs. For example, a three-part arrangement can be provided in which the guide means are positively connected to the spacing means. As part of a stable arrangement, the guide means can alternatively also be connected to one another in a materially bonded manner, for example via an arc welding process (eg a TIG welding process) or via a beam welding process (eg a laser welding process).

With a view to ensuring processing of a substrate during a recording, in particular particularly homogeneous processing of a substrate during a recording, it can advantageously be provided that the spacing means has recesses for contacting the substrate, the recesses preferably being arranged symmetrically within the receiving unit , in particular in the form of cutouts arranged along the length. In particular, this allows direct contact to be made with the substrate during processing, for example by means of cleaning fluids, drying air, coating agents and the like.

In the context of a particularly compact arrangement and ensuring particularly homogeneous processing of a substrate, it can advantageously be provided that the spacing means is shaped as a hollow cylinder and is arranged symmetrically within the receiving unit, preferably arranged within the receiving unit in such a way that the recesses of the spacing means at least partially, in particular completely, overlap with the recesses of the receiving unit.

The magnet can preferably be cylindrical in shape and have a diameter of less than 20 mm, preferably less than 15 mm, in particular less than 10 mm. As a result of the encapsulation, it is possible that the magnetic force is only used for fixation and cannot adversely affect processing operations to be carried out, such as coating operations, in particular plasma coating operations or the like. A suitable magnet in connection with a corresponding encapsulation offers the particular advantage of ensuring a secure fixation in connection with a simultaneous slight influence on the machining operations to be carried out.

With regard to a structurally simple possibility of magnetic shielding, it can be specifically provided that the magnet is arranged within the holding unit in such a way that a material thickness of at least 0.5 mm of the holding unit is arranged between the magnet and the receiving unit arranged directly on the holding unit .
