Description

Technical Field

[0001] The invention relates to a handheld device, a structure, a method, a computer-readable storage medium and a software program. Background Art

[0002] When installing expansion bolts in a substrate, knowledge of the substrate into which they are to be installed is crucial for planning the installation process. Especially in the case of renovations or unknown substrate conditions, the substrate is often unknown.

[0003] By observing the drill cuttings, a trained user can infer rough information about the substrate. White drill cuttings might indicate drywall or limestone, red drill cuttings indicate a brick substrate, etc. Certain inferences can also be made based on events determined when making the drill hole: almost no drill progress might indicate concrete, jerky movements while drilling might indicate hollow brick, and normal drill progress might indicate a continuous substrate.

[0004] However, in many cases the described aids do not allow accurate deductions to be made for the actually existing substrate and require experience and technical expertise that some users lack. This promotes installation errors and reduces reliability and safety when installing screws, etc. in unknown substrates. Summary of the invention

[0005] The object of the present invention is to be able to process a substrate, in particular to produce a bore hole in the substrate and / or to attach a fastening element, in a simple and error-proof manner.

[0006] This object is achieved by a solution having the features according to the independent claim. Further embodiments are indicated in the dependent claims.

[0007] According to one embodiment of the present invention, a handheld device for manual operation by a user is proposed, which has a processing device designed to process a substrate, and a sensor device designed to detect data representing characteristics of the substrate before, during and / or after processing the substrate.

[0008] According to another embodiment of the present invention, a structure is provided, which has a handheld device having the above-mentioned characteristics and a communication device, which is connected or capable of being connected to the handheld device in a communicative manner for transmitting sensor data from the handheld device to the communication device, and has a determination device, which is designed to determine information indicating characteristics of a substrate based on the transmitted sensor data, wherein the communication device is designed to transmit information to the handheld device, and the handheld device is used to receive information from the communication device.

[0009] According to another embodiment of the present invention, a method for operating a handheld device (in particular, a handheld device having the above-mentioned features) that can be manually operated by a user and is used to process a substrate is provided, wherein the method comprises, with the aid of the handheld device: detecting sensor data indicating characteristics of the substrate before, during and / or after processing the substrate with the aid of the handheld device; and determining information indicating characteristics of the substrate based on the sensor data, in particular on the handheld device or on a communication device that can be communicatively connected to the handheld device.

[0010] In a computer-readable storage medium according to an embodiment of the present invention, a program for running a handheld device for processing a substrate that can be manually operated by a user is stored, and when the program is executed by one or more processors, it has or performs the above method steps.

[0011] According to one embodiment of the present invention, a software program (for example, formed by one or more computer program elements) for running a handheld device that can be manually operated by a user for processing a substrate has the above-mentioned method steps (or executes or controls the above-mentioned method steps), and in this case, the method steps are executed by one or more processors.

[0012] The embodiments of the present invention may be implemented by a computer program (ie, software), by means of one or more specific circuits (ie, hardware), or in any mixed form, ie, by means of software parts and hardware parts.

[0013] In the scope of the present application, "handheld device" can be understood as a portable device that can be manually operated and carried by a user and by which the processing of the substrate is realized. In particular, a borehole can be drilled in the substrate by means of a handheld device and by applying a driving force, and / or a driving force can be applied to a fixed element to be installed in the substrate. The driving force can be a rotational or rotating driving force, optionally superimposed with a translational driving force. In other words, the handheld device can be designed to rotate the driving processing device and thus rotate the driving drill and / or the fixed element. However, alternatively, the driving force can also be a pure translational driving force. The driving force of the handheld device can be a pneumatic, hydraulic or electric driving force, such as generated by a pneumatic device, a hydraulic device or an electric motor, or it can be the user's physical strength. Examples of manual devices are battery screwdrivers, battery drills, rotating screwdrivers, pulse screwdrivers, ratchet screwdrivers, drills, impact screwdrivers and electric hammers. Other examples of manual devices include screw wrenches, crank wrenches, ratchets or torque keys.

[0014] In the context of the present application, the term "processing device" is to be understood in particular as a mechanism or component which is capable of processing a substrate, in particular material-removing processing or drilling a borehole. In particular, the processing device can have a drill bit accommodated in a chuck for drilling a borehole in the substrate. However, the processing device can also have a drill bit accommodated in a chuck for operating a driver in the head of the fixing element in order to introduce the fixing element (with or without a pre-drilled hole) into the substrate with the aid of a handheld device. After the substrate has been processed by the processing device, the fixing element can be installed in the already formed borehole, optionally in combination with an expansion bolt.

[0015] Within the scope of the present application, a "fixing element" is to be understood in particular as an object that can be introduced into a substrate or an anchoring substrate by means of a handheld device, in particular by rotation. Preferably, the fixing element is a screw, for example a wood screw for insertion into an anchoring substrate made of wood. Alternatively, the fixing element can also be, for example, a nail or a rivet. The fixing element can be designed so that it can be introduced into the anchoring substrate without a pre-drilled hole or after a pre-drilled hole has been formed. The rotationally introduced fixing element can have a self-tapping or self-cutting external thread. The fixing element can be installed in the substrate with or without expansion bolts. For example, if the substrate has a cavity and the pull-out force of the fixing element is not large enough without expansion bolts due to the cavity, expansion bolts can be advantageous.

[0016] In the context of the present application, the term "substrate" is to be understood in particular as an anchoring substrate suitable for anchoring a fixing element. Such an anchoring substrate can in particular be or have a wall, more particularly a vertical wall. The material for such an anchoring base is in particular wood or wooden building materials, but also concrete and masonry building materials, metal or plastic parts. Furthermore, such a substrate material can also be any composite material made of several different material components. The substrate material can have cavities or be solid (i.e. without cavities).

[0017] In the context of the present application, the term "sensor device" is to be understood in particular as one or more sensor elements for generating sensor data which allow conclusions to be drawn about at least one property of a substrate processed by the handheld device. Such a sensor device can be designed to enable optical detection, force detection, temperature detection, speed detection and / or acceleration detection, acoustic detection, tactile detection, electrical, magnetic or electromagnetic detection, etc. It is particularly advantageous that several of the mentioned detection mechanisms and other detection mechanisms can be combined with one another.

[0018] In the context of the present application, the term "properties of the substrate" may be understood in particular to mean properties of the substrate that are critical for processing the substrate with the handheld device. In particular, such properties of the substrate may be associated with processing with the handheld device or with a mounting process for mounting a fixing element in the substrate. Examples of property information about the substrate include its material, its solid or hollow nature, its hardness, its moisture content, etc.

[0019] According to an exemplary embodiment of the present invention, a handheld device is provided, which is equipped with a sensor device for detecting sensor data indicating the characteristics of a substrate. In this way, the handheld device can detect sensor data before, during or after processing the substrate, and the sensor data allows inferences about the characteristics of the substrate to be drawn. In this way, the process of processing the substrate by the user using the handheld device and / or the corresponding post-processing of the processed substrate (for example, the installation process for installing a fixing element in a previously formed drilled hole) can be adapted to the determined substrate characteristics. It is thus possible to process the substrate, for example, to form a drilled hole or to install a fixing element in the substrate in a simplified and error-proof manner based on objective sensor data. In this regard, the user's special expertise or experience is irrelevant. Since the sensor device is integrated into the handheld device for processing the substrate, the user only needs to operate the handheld device to obtain sensor data characterizing the substrate through the handheld device in addition to processing the substrate with the handheld device.

[0020] Additionally, exemplary embodiments of a handheld device, structure, method, computer-readable storage medium, and software program are presented.

[0021] According to an exemplary embodiment, the handheld device can have a determination device which is designed to determine information indicating a property of the substrate based on the sensor data. According to the described design, the handheld device itself can thus autonomously evaluate the sensor data and draw inferences about the properties of the substrate therefrom. The substrate can then be further processed taking into account the determined properties of the substrate.

[0022] According to another exemplary embodiment, the handheld device may have a communication device for communicating with a communication device that can be communicatively connected and is separate from the handheld device (in particular wirelessly or by wire) to transmit sensor data to the communication device, wherein the communication device is designed to receive information indicating characteristics of the substrate from the communication device, which information can be determined based on the sensor data transmitted to the communication device. According to this design, the sensor data is only detected on the handheld device and centrally evaluated on the communication device that can be communicatively connected. In this way, the handheld device can be designed to be compact and light, and the data evaluation for determining the characteristics of the substrate based on the sensor data detected on the handheld device is performed centrally on the commonly used communication device for multiple handheld devices.

[0023] According to an exemplary embodiment, the processing device can be designed as a drilling device for drilling a hole in a substrate and / or as an installation device for installing a fixing element in a substrate. In particular, the processing device can be designed to penetrate at least partially into the substrate. The processing device can in particular have a chuck for accommodating a drill bit, which can also belong to the processing device. Therefore, the handheld device can preferably be designed as a drill with an integrated sensor device for characterizing the substrate to be drilled. Instead of a drill bit, a screwdriver can also be accommodated on the chuck in order to screw the fixing element into the substrate (for example, into a previously drilled hole).

[0024] According to an exemplary embodiment, the sensor device can have an optical sensor device, in particular a camera, for detecting optical sensor data of the substrate and / or the processing device, in particular the material coming out of the interior of the substrate, and further in particular the drill cuttings coming out of the interior of the substrate. Accordingly, the determination device for determining information indicating the characteristics of the substrate is designed based on the color of the interior of the substrate determined according to the optical sensor data. For example, such an optical sensor device can detect an image of the outside and / or the inside of the drill hole. Thereby, the quality of the drill hole in the substrate can be determined. In addition, the material of the substrate can be characterized or determined by analyzing the drill cuttings and / or the wall of the drill hole using the optical sensor device. Such an optical sensor device can be used in particular to determine the color of the drill cuttings. The color of the drill cuttings can draw inferences about the material of the substrate material. For example, white drill cuttings can indicate lime sand bricks or porous concrete, gray drill cuttings can indicate concrete or concrete blocks, red drill cuttings can indicate bricks, etc. The drill cuttings analysis performed using the optical sensor device can also provide information about the moisture of the substrate, in particular determine whether dry or wet drill cuttings are present. This is because the moisture in the substrate material affects its color, so it can be detected optically.

[0025] According to an exemplary embodiment, the determination device can be designed to determine the error state of the processing device based on the optical sensor data. For example, by using the sensor data of the optical sensor device in combination with pattern recognition, it is determined whether the scrap mark on the concrete drill bit is exposed.

[0026] According to an exemplary embodiment, the sensor device can have a distance measuring device, in particular a laser sensor or an ultrasonic sensor, for acquiring distance data between the handheld device and the substrate. Accordingly, the determination device can be designed to determine information indicative of a characteristic of the substrate based on the penetration progress (for example of a drill bit of a processing device) into the substrate determined by the distance data, in particular the time correlation of the penetration progress. For example, the distance sensor can measure the distance between the handheld machine and the substrate and in this way provide information about the penetration progress. For example, if the drill bit drills into a cavity of a hollow brick, the distance will suddenly decrease until the drill bit drills into the next lintel of the hollow brick. Therefore, the sudden change in distance detected by the sensor can be used as an indicator of the presence of a substrate with a cavity. The length of time of the jerk can be used as a measure of the size of the cavity.

[0027] According to an exemplary embodiment, the handheld device may have a drive device for providing drive energy to drive a processing device for processing a substrate. The sensor device may have a drive energy measuring device, in particular a tachometer of a motor of the drive device, for detecting the drive energy used to drive the processing device. Accordingly, the determination device may be designed to determine information indicating the characteristics of the substrate, in particular the hardness of the substrate and / or the presence or size of at least one macroscopic cavity in the substrate based on the detected drive energy, in particular the time correlation of the detected drive energy. The harder the substrate, the more difficult the motor operation is and the greater the drive energy. A sudden, temporary drop in the drive energy within a time period can provide information about the presence and / or size of the cavity. The motor current, motor torque and / or motor power can be reduced as information sources.

[0028] According to an exemplary embodiment, the sensor device can have a push force measuring device for detecting the pressure of the processing device on the substrate. In particular, the determination device can then be designed to determine information indicating the characteristics of the substrate, in particular the hardness of the substrate and / or the presence or size of at least one macroscopic cavity in the substrate based on the detected push force, in particular the time correlation of the detected push force. The push force or pressing force can be measured, for example, by a capacitive sensor. The harder the substrate material, the higher the required pressing force. When penetrating the cavity in the substrate, the push force drops suddenly and temporarily.

[0029] According to an exemplary embodiment, the sensor device can have a temperature measuring device, in particular an infrared sensor, for detecting the temperature of the processing device during and / or after penetration of the substrate. In particular, the determination device can then be designed to determine the hardness of the substrate and / or an error state of the processing device based on the temperature. For example, such a temperature measuring device can detect the temperature of the drill bit after the formation of the drill hole in the substrate. The hotter the drill bit is after performing this drilling task, the harder the substrate is. Such a temperature measuring device can also be used to measure overheating of the drill bit. If the latter error is detected, appropriate measures can be taken (e.g. alarm, emergency stop, etc.).

[0030] According to an exemplary embodiment, the sensor device can have a humidity measuring device for detecting the moisture or humidity of the substrate. In a corresponding manner, the determination device can then be designed to determine information indicating the characteristics of the substrate based on the detected humidity. For example, an optical sensor device can be used to measure humidity, because the color of the substrate material is different in a wet state and in a dry state. However, a liquid sensor or a chemical sensor can also be used to measure humidity. The more moist the substrate is, the more difficult the installation process of the fixing element is. For moist substrate materials, for example, it may be necessary to use longer fixing elements or additionally use expansion bolts to ensure sufficient installation force.

[0031] According to an exemplary embodiment, the determination device can be designed to determine information by comparing the sensor data with a previously known data set from a database. Preferably, sensor data characterizing different handheld devices and different substrates and / or substrate properties are available in the database. For example, empirical data from experiments, data from model calculations, expert rules and / or artificial intelligence elements can be used to match the sensor-determined parameter values ​​of the substrate (e.g., sudden changes in cuttings color, contact force, motor power) with the properties of the substrate (e.g., material, hardness, cavity size). The sensor data detected by means of the sensor device can then be matched to the properties of the substrate by means of a database comparison, for example, by searching a lookup table.

[0032] According to an exemplary embodiment, the handheld device may have storage means in which the data sets in the database are stored. Thus, the data sets may be stored in the storage means of the handheld device itself, such as an electronic mass storage device, such as a hard disk. The database comparison may then be performed independently on the handheld device to determine the information.

[0033] According to another exemplary embodiment, the handheld device may have a communication device for communicating with another communication device (particularly wirelessly or by wire) that can be communicatively connected and is separate from the handheld device, on which data sets in the database are stored. According to this design, the handheld device itself only detects sensor data, but can access the communication device that can be communicatively connected to determine the information about the substrate generated thereby. The connection between the communication device of the handheld device and the communication device can be made, for example, via a wireless communication network, such as the public Internet. This wireless communication can also be achieved directly, for example, via Bluetooth. In addition, this communication can be carried out by wire. According to the described embodiment, a large number of handheld devices can be supported simultaneously or sequentially when comparing databases with the help of a single communication device. Then, a single central intelligent component can cooperate with multiple decentralized handheld devices of simple design.

[0034] According to an exemplary embodiment, the handheld device may have a control device for controlling the handheld device (in particular the processing device and / or the drive device of the handheld device) based on the determined information indicating the characteristics of the substrate. The results of the determined characteristics of the substrate can then serve as a basis for subsequent operation of the manual device for processing the substrate. Thus, the hardness of the substrate can be a measure of which motor power is set by the control device. It is also feasible that the torque of the drive motor is temporarily reduced when it reaches the next cavity.

[0035] According to an exemplary embodiment, the handheld device can have a user interface for outputting operating suggestions for the handheld device, in particular suggestions for the use of expansion bolts and / or fixing elements for the substrate, based on the determined information indicating the characteristics of the substrate. For example, the user interface can include a graphical user interface with a graphic display device such as a liquid crystal display. There, suggestions can be made for the processing of a substrate that has been characterized in advance with regard to its characteristics. For example, if the substrate is found to be a substrate with a large cavity, it can be suggested to use expansion bolts of corresponding set size in combination with relevant fixing elements (such as suitable screws). Thereby, the user can be provided with an operating method suitable for previously unknown substrates in an intuitive manner.

[0036] According to an exemplary embodiment, a user interface for outputting operating recommendations for a handheld device, in particular recommendations regarding the use of expansion screws and / or fixing elements for a substrate, can be designed additionally based on load requirements specified by the user for anchoring the fixing element in the substrate. The user recommendations for processing a substrate characterized in terms of its properties can advantageously be refined so that in addition to the determined substrate properties, the load requirements specified by the user, such as a guaranteed load capacity or a pull-out force, are also taken into account. In this way, failures of the fixing element in the substrate can be prevented with a high probability, since both the loads occurring during operation and the actual substrate properties can be included in the user recommendations.

[0037] According to an exemplary embodiment, the sensor device can be designed to detect or identify the fixing element to be installed. The handheld device can advantageously have a control device, which is designed to control the processing device for installing the fixing element based on the result of the detection or identification. For example, by means of an optical sensor device, advantageously in combination with pattern recognition on a camera image, the fixing element used with the handheld device can be identified by the sensor (for example an M8 screw with a length of 100 mm and a plum drive). In combination with the information about the substrate properties determined by the sensor, the identified fixing element can be brought into an algorithm, which, for example, using database information from the provided input data, accordingly calculates the installation process of the identified fixing element and subsequently controls the installation process.

[0038] According to an exemplary embodiment, the handheld device can be a drill. Alternatively or additionally, the handheld device can be a battery screwdriver, a battery drill screwdriver, a rotary screwdriver, a pulse screwdriver, a ratchet screwdriver, an impact screwdriver and / or an electric hammer or have corresponding functions.

[0039] According to an exemplary embodiment, the sensor device can have at least two different sensor types, which are designed independently of each other and detect sensor data indicating the characteristics of the substrate according to different sensor principles. Then, the determination device can be designed to determine information based on the sensor data so that the determined information is only accepted or further used when it is provided independently of each other and mutually confirmed by at least two different sensor types. Different sensor types can be, for example, the above-mentioned optical sensor device and force sensor. Due to the different sensor principles assigned to the sensor types, the sensor data provided by them can be regarded as complementary or independent of each other. Only when the determined characteristics of the substrate (such as the characterization of the cavity in the substrate) are indicated and shown consistently by both parties or even by all the sensor types used, the determined characteristics of the substrate are confirmed or further used, otherwise the characteristics can be considered to be unreliable and discarded. In this way, erroneous outputs can be effectively suppressed.

[0040] According to an exemplary embodiment, in this structure, the handheld device can be designed to transmit information and the communication device can be designed to receive and store information, which documents the actual drilling process of the borehole and the actual installation process of the fixing element in the substrate, that is, indicates the actual state of the substrate processing. The nominal state of the substrate processing can be predefined and compared with the determined actual state. For example, storage data for a building archive can be stored. The building archive specifies which fixing elements are installed in which boreholes at which positions in the substrate. By storing data for archiving the actual construction process, it can be checked whether the nominal installation data are consistent with the actual situation in accordance with the given plan.

[0041] According to an exemplary embodiment, the method may include processing the substrate with the aid of a robot, wherein the robot processes the substrate with the aid of a handheld device using at least a portion of the sensor data. For example, the robot may autonomously perform a prescribed substrate processing file using the handheld device and the sensor data detected by the handheld device. Because the handheld device is equipped with sensors according to an embodiment of the present invention, the handheld device is particularly suitable for performing substrate processing tasks in a robot-operated manner. For example, the sensor data may be transmitted to the robot. For example, the robot may use the handheld device to perform a predetermined substrate processing file on the substrate, such as making a series of drill holes and placing corresponding fixing elements therein. The sensor data may enable the robot to operate the handheld device in a particularly error-proof manner. For example, it may be recognized that the substrate characteristics detected by the sensor (e.g., "the substrate is full concrete") contradict the substrate processing file (e.g., "installing wood screws without pre-drilling"). In this case, appropriate measures may be taken (e.g., canceling the substrate processing, outputting an error message, etc.). BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the following drawings.

[0043] Figure 1 A handheld device designed as a drilling machine with an integrated sensor device and a determination device for determining a property of a substrate is shown according to an exemplary embodiment of the invention.

[0044] Figure 2 According to a further exemplary embodiment of the present invention, a structure is shown consisting of a handheld device designed as a drilling machine with an integrated sensor device and a communication device communicatively coupled thereto, which has a determination device for determining a property of a substrate.

[0045] Figures 3 to 5 A substrate that has been processed with the aid of a handheld device and measured in a laboratory according to an exemplary embodiment of the present invention is shown for populating a database with a data set for correlating characteristics of the substrate with sensor data and correlating processing characteristics of such substrate with the handheld device. DETAILED DESCRIPTION

[0046] Identical or similar components in different figures are provided with the same reference signs.

[0047] Before describing exemplary embodiments of the present invention with reference to the accompanying drawings, some general aspects of embodiments of the present invention should be explained:

[0048] According to an exemplary embodiment of the invention, a handheld device, in particular a drilling machine, can be provided, which uses sensors to identify a substrate that has been processed or is to be processed by it and thus enables characterization of the substrate. The sensor data detected by the handheld device can be further processed by the handheld device or a communication device connected to the handheld device for data exchange, so as to derive information characterizing the substrate based on the sensor data. This enables the user to obtain information about a previously unknown or only partially known substrate, or enables the processing of the substrate by means of the handheld device to be controlled or refined.

[0049] In particular, the combination of drilling machine and drill bit can be equipped with at least one sensor for measuring the drilling depth and / or the drilling progress. For example, a jerky or uniform drilling progress can be an indicator of the presence of hollow bricks or solid bricks in the substrate. If a sensor is provided as an alternative or in addition for determining the force required for drilling or setting a fixing element in the substrate, it can be determined by the sensor with how hard the handheld device must work for the drilling process or the setting process. This in turn enables inferences to be drawn about the substrate, in particular its hardness and / or material. For example, if porous concrete is present, this can be indicated by white drill cuttings detected by means of an optical sensor and by only very low forces or energies used to produce the drill hole. A substrate consisting of solid sand-lime bricks can be identified by white drill cuttings and an increased force used to produce the drill hole. Therefore, the combination of the drill cutting color detected by the sensor and the drilling force detected by the sensor is a particularly reliable indicator of the properties of the substrate.

[0050] According to a preferred embodiment, the handheld device can communicate with a communication device, through which the drilling plan and / or the installation plan of the building or substrate are managed. In this article, data for building archives can be advantageously stored. The data of such a plan can then be checked to see if it conforms to the actual situation of the substrate.

[0051] According to an embodiment of the invention, communication with a screwdriver is also possible. The screwdriver can at least suggest a torque for future installation of wall screws based on the drill's data and the results of laboratory tests (which can be stored in a database, for example).

[0052] The method described here primarily for drill bits can also be advantageously transferred to other machines or handheld devices.

[0053] With regard to the screwing-in process of the fixing element designed as a screw, according to an exemplary embodiment of the present invention, the tightening of the screw can be controlled based on the substrate characteristics detected by the sensor and determined by means of sensor data processing. For example, the torque for installing the fixing element can be increased or decreased depending on the distance to the substrate, etc.

[0054] According to one embodiment, the power, current, torque, etc. of a driving device of a drill or another handheld device may also be taken into account to obtain information about the substrate.

[0055] When installing expansion bolts, knowledge of the substrate into which they are to be installed is crucial for a successful anchoring. In particular in the case of refurbished or unknown substrates, an incomplete or completely missing knowledge of the substrate can be improved or obtained by information about the substrate characteristics detected and evaluated by means of sensors according to exemplary embodiments of the present invention. For example, a camera can automatically record flying drill cuttings, so that the range of substrate materials can be narrowed down based on image data and their evaluation. Force sensors or pressure sensors can detect the pressure applied during the drilling process, which provides more information about the hardness of the substrate. In particular, when at least two or more values ​​detected by sensors are combined or combined to consider consistency or differences, particularly reliable or meaningful inferences about the substrate can be drawn. Possible inaccuracies or incorrectness of measurements with only one sensor can be advantageously avoided by combining a plurality of different sensor measurements.

[0056] The data sets in the database that can be compared with the sensor data detected by the sensors in order to deduce information about the properties of the substrate can be generated, for example, in a laboratory, more specifically in a bolt laboratory. In the bolt laboratory, bolts can be installed in different substrates with corresponding test holes (for example as the basis for the approval of individual bolts). Here, the drilling progress, the color of the drill cuttings, etc. can be detected and the data sets can be stored centrally in a database (for example on a server).

[0057] If a user (e.g. a craftsman) then makes a borehole, his drill detects the corresponding sensor data, transmits this sensor data to the server and receives feedback or predictions from there about what kind of substrate is or is likely to be present. The craftsman can then select or obtain an expansion bolt or directly receive a suggestion about which expansion bolt is suitable for this substrate.

[0058] In particular, a handheld device designed as a drill can use a force sensor to detect the force applied to form a drill hole. From this, for example, inferences can be drawn about the strength of the substrate (mainly in walls). In particular, a rangefinder can be used in combination with a force sensor to detect the hole pattern in a substrate (e.g. masonry). The substrate can then be characterized using a camera to determine the color of the drill cuttings.

[0059] If such a handheld device designed as a drill communicates, for example, with a tangential screwdriver for installing concrete screws, the tangential screwdriver can set the correct torque for the characterized substrate, for example preventing the concrete screw from being overtightened in the drill hole and / or the concrete screw head from being sheared.

[0060] Thus, one or more additional sensors may be provided in and / or on the drilling rig, any combination being possible depending on the application. Examples of sensor devices that may be advantageously implemented are:

[0061] a distance meter, used to measure the distance between the substrate and the drill bit;

[0062] A force sensor for measuring the pressing force of the handheld device on the substrate;

[0063] a camera to capture drill cuttings as the hole is drilled into the substrate;

[0064] Detect motor data, such as current, power, torque, and speed;

[0065] Acceleration sensors, especially three-dimensional acceleration sensors;

[0066] Infrared sensor for detecting infrared radiation emitted, for example, from a heated drill head of a handheld device.

[0067] The distance meter can be designed, for example, as an ultrasonic sensor, a laser beam sensor or a 3D acceleration sensor. The hole pattern in the substrate can be detected by such a distance meter in combination with a force sensor. The drilling progress, in particular any setbacks in the drilling progress, can be detected with the aid of the distance sensor, which indicates a hollow brick.

[0068] In addition, a drill or other handheld device can use a force sensor to detect the force applied to form the drill hole. From this, inferences can be drawn about the strength of the substrate (mainly in the case of a wall).

[0069] The detection of the motor data allows inferences to be drawn about how hard the handheld device must work to complete the processing task, especially the drilling task. This in turn allows inferences to be drawn about the substrate. In the case of porous concrete, the combination of white drill cuttings and only a small amount of force or energy can form a drill hole. If solid sand-lime brick is present, white drill cuttings and increased difficulty in producing the drill hole will appear.

[0070] An infrared sensor can be provided to detect the temperature of the drill bit after drilling.

[0071] The color of the drill cuttings can be determined using a camera, for example, and on this basis the substrate can be characterized. The camera records the flying drill cuttings, which can then be narrowed down to the substrate material. This can be advantageously combined with determining whether the drill cuttings are dry or moist. If all these values ​​are aggregated, inferences can be drawn about the substrate.

[0072] The selection of suitable expansion bolts can also be based on the determined knowledge of the substrate properties. This can advantageously be supplemented by the user input of the required load. Thus, the software can be used to specifically propose better or more suitable suggestions for the existing application situation and the current substrate and the load expected by the user, for example, by a software-based expansion bolt suggestion system.

[0073] For example, a WLAN connection or a data cable may be used to provide communications between a handheld device (eg, a drill) and a communications device (eg, a computer).

[0074] In this communication, it is possible to store which fixing element is installed at which location in the space. It is also possible to store whether the reinforcement was drilled into during the drilling process. It is also possible to store data for the building archive. It is then possible to determine whether the planned data is consistent with the actual situation.

[0075] A further application of the drill bit according to an exemplary embodiment of the invention relates to a scenario in which a drill recognizes a component to be installed. The drill can then use the data from the drill and the results of the laboratory tests to suggest at least one torque for screwing in a future wall and can even control the screwing process according to the determined substrate properties. In the case of wood screws, the torque can be increased and decreased depending on the distance to the substrate material, etc. Conversely, in the case of concrete screws or concrete anchors, the torque for installation can be set which is correct for the substrate.

[0076] Figure 1 A handheld device 100 designed as a drilling machine with an integrated sensor device 106 and a determination device 108 for determining a property of a substrate 104 is shown according to an exemplary embodiment of the present invention.

[0077] The handheld device 100 shown, which is designed as a drill, has a drill bit 160 which is mounted in a replaceable manner on a chuck 162. The chuck 162 and subsequently the drill bit 160 are driven in rotation by a drive device 114 designed as an electric motor in order to form a borehole in a substrate 104, such as a concrete wall or a hollow brick wall. The drive device 114 obtains the drive energy from an energy storage device 164 or alternatively obtains the drive energy from a cable connection to the power grid. The drive device 114 is controlled by a control device 122, and the user can influence the process of controlling the handheld device 100 by actuating a control device 166 on a wrench 170. The mentioned components are mounted on or in a housing 168.

[0078] Figure 1 The handheld device 100 shown in FIG. 1 is designed as a portable drilling device for manual operation by a user and has a processing device 102, which is designed for drilling a substrate 104, i.e. for forming a borehole in the substrate 104. The processing device 102 is formed by a drill bit 160 and a chuck 162. In operation, when drilling a borehole in the substrate 104, the processing device 102 penetrates the substrate 104 with its drill bit 160.

[0079] In addition, the handheld device 100 also includes a Figure 1A sensor device 106 formed from a plurality of individual sensors is designed to detect sensor data indicative of properties of the substrate 104 before, during and / or after the substrate 104 is processed by means of the processing device 102. Properties of the substrate 104 are understood to be, for example, the material of the substrate 104, the hardness of the substrate 104 and the presence or absence and, if necessary, the size of cavities in the substrate 104. The sensor device 106 is described in more detail below.

[0080] Furthermore, the handheld device 100 has a determination device 108, which is designed, for example, as a processor 128, as a plurality of processors 128 or as part of a processor 128. The determination device 108 is designed to determine information indicative of a property of the substrate 104, i.e. information indicative of a property of the substrate 104, based on sensor data detected by sensors of the sensor device 106 and provided to the determination device 108.

[0081] like Figure 1 As shown, the sensor device 106 has an optical sensor device 130, which in the embodiment shown is designed as a camera mounted on a housing 168. This is used to detect optical sensor data of the substrate 104, i.e. to take an image 198 of the processed area of ​​the substrate 104. The camera can also capture an image of the drill bit 160 or a part of it. It is particularly preferred to detect drill cuttings flying out of the interior of the substrate 104 when drilling with the processing device 102 with the aid of a camera. In this context, the determination device 108 is used to determine information indicating properties of the substrate 104 based on the color of the drill cuttings from the interior of the substrate 104 determined from the optical sensor data. The color of the substrate 104 can be inferred from the color of the drill cuttings, in particular when a data set pre-stored in this regard is contained in the database 120 (this can also be done, for example, based on Figure 2 Design). Figure 1 , the database 120 may be stored in the storage device 118 of the handheld device 100 .

[0082] The determination device 108 can also detect a possible error state of the processing device 102 based on the optical sensor data. For example, it can be recognized from the image captured by the camera that the scrap mark of the drill bit 160 is exposed, indicating that the drill bit 102 has been used to scrap. Then, a warning can be output to the user on the user interface 124, which is designed as a display device, for example, that the drill bit 160 has been scrapped and should be replaced.

[0083] The camera can also be used as a moisture measuring device for detecting moisture in the substrate 104, because the color of the drill cuttings detectable by the camera is different in the wet state and the dry state. Therefore, the moisture content of the substrate 104 can also be determined or at least estimated by the determination device 108 by means of the sensor data of the camera.

[0084] In addition, the sensor device 106 includes a distance measuring device 132, which is designed as a laser sensor or an ultrasonic sensor, for example. The distance measuring device is used to detect distance data between the substrate 104 and the handheld device 100. In a corresponding manner, the determination device 108 is used to determine information indicating the characteristics of the substrate 104 based on the penetration progress of the drill bit 160 into the substrate 104 determined according to the distance data. In particular, the time correlation of the penetration progress of the drill bit 160 into the substrate 104 is of interest, because the existence of a cavity in the substrate 104 can be derived from this. If the distance changes suddenly, the drill bit 160 has entered a new cavity. After reaching the next crossbar 104 in the substrate 104, the distance decreases very slightly over time until the next cavity is reached and the next sudden distance reduction is thus achieved.

[0085] As already mentioned, the handheld device 100 includes a drive device 114, which is designed here as an electric motor, for providing drive energy for driving the processing device 102, in particular for driving the chuck 162 and thus the drill bit 160 connected thereto in a rotationally fixed manner. Figure 1 As shown, the sensor device 106 further includes a drive energy measuring device 134, which can be designed as a tachometer of the electric motor of the drive device 114, for example. The drive energy measuring device 134 is used to detect the drive energy used to drive the processing device 102. The determination device 108 is further used to determine the hardness of the substrate 104 and / or at least one macroscopic cavity (see Figures 3 to 5 116 in the figure) in the substrate 104. If the drive energy suddenly decreases, the drill bit 160 enters a new cavity. After reaching the next lintel in the substrate 104, the drive energy increases again until the next cavity is reached and the drive energy temporarily decreases again.

[0086] Furthermore, the sensor device 106 has a pressing force measuring device 136 for detecting the pressing force of the processing device 102 on the substrate 104, for example, in a capacitive manner.

[0087] Accordingly, the determining device 108 is used to determine information indicating the characteristics of the substrate 104 based on the time correlation of the detected thrust force, i.e. the hardness of the substrate 104 and / or the presence or size of at least one macro cavity 116 in the substrate 104. If the thrust force suddenly decreases, the drill bit 160 has entered a new cavity. After reaching the next lintel in the substrate 104, the pressure increases again until the next cavity is reached.

[0088] Furthermore, the sensor device 106 has a temperature measuring device 138, which can be designed as an infrared sensor. Therefore, the temperature measuring device 138 is used to detect the temperature of the processing device 102, more precisely the temperature of the drill bit 160 during and / or after drilling into the substrate 104. Therefore, the determination device 108 is designed to: determine the hardness of the substrate 104 and / or an error state of the processing device 102 based on the detected temperature. The higher the hardness of the substrate 104, the more obvious the temperature increase of the drill bit 160 when drilling a hole in the substrate 104. If it is detected that the temperature of the drill bit 160 is higher than the allowed range, the user interface 124 can be used to issue an alarm to the user or even stop the operation of the handheld device 100 by emergency stop.

[0089] The sensor data of the various sensors of the sensor device 106 are fed to the determination device 108. The determination device 108 is designed to determine information by comparing the sensor data with previously known data sets from the handheld device's own database 120. As already introduced, the handheld device 100 has a storage device 118 for this purpose, in which the data sets in the database 120 are stored. The database 120 can be filled with data sets obtained, for example, in the laboratory using experimental substrate processing processes. In particular, the database 120 contains corresponding characteristics of different substrates 104 for different handheld devices 100 and for different sensor devices 106 or corresponding sensor data. Then, the data comparison between the sensor data and the data in the database 120 enables the substrate 104 to be characterized.

[0090] The control device 122 is advantageously designed to control the processing device 102 based on the information determined and indicative of the properties of the substrate 104. In other words, the control device 122 can use the sensor-based characterization of the substrate 104 as an opportunity to correspondingly adapt the subsequent processing of the substrate 104 by means of the drill 160 or by means of a screwdriver for inserting a fastening element into a drill hole. For example, if the characteristics of the substrate 104 already indicate the presence and size of a cavity 116, the drive energy of the drive device 114 can be reduced before the drill 160 reaches the next cavity 116.

[0091] As already introduced, the handheld device 100 has a display device or a graphical user interface 124 for outputting operating suggestions for the handheld device 100. As a result, in particular, it is possible to output to the user in an intuitive manner a usage suggestion for an expansion bolt for a substrate 104 characterized in terms of its properties. Such a suggestion can be created based on information determined and indicating the properties of the substrate 104. The user interface 124 can also be designed to output operating suggestions for the handheld device 100 based on the load requirements specified by the user for anchoring the fixing element in the substrate 104. In other words, the user can, for example, input the load requirements that should at least be met for the installation task of the fixing element via the user interface 124. The control device 122 can then control the operation of the handheld device 100 so that the substrate 104 characterized by the sensor and the specified load requirements are taken into account when outputting the suggestions or presenting the recommendations.

[0092] If a fixing element, such as a screw, is to be installed in the drill hole after the drill hole is formed, the sensor device 106 can be designed to identify or detect the fixing element to be installed. Then, the control device 122 can be designed to control the processing device 102 so as to install the fixing element based on the result of the detection or identification.

[0093] In particular, the combined detection of a plurality of different or complementary sensor data by a sensor device 106 comprising different sensor types 130, 132, 134, 136, 138 (e.g. optical sensors and force sensors) has proven to be a powerful approach to exclude or at least greatly suppress artificial and possibly incorrect inferences about properties of the substrate 104, which could lead to erroneous outputs when only one type of sensor is considered in unfavorable circumstances. For example, the determination device 108 can be designed to accept that an inference about a property of the substrate 104 is correct only if at least two different sensor types 130, 132, 134, 136, 138 consistently indicate this property of the substrate 104.

[0094] According to another exemplary embodiment of the present invention, Figure 2 An arrangement 126 is shown which consists of a handheld device 100 designed as a drilling machine with an integrated sensor device 106 , a communication device 112 communicatively coupled thereto, and a determination device 108 for determining a property of a substrate 104 .

[0095] exist Figure 2 The structure 126 shown in FIG. 1 has a design based on Figure 2 The handheld device 100 and the communication device 112 of the drilling rig are communicatively connected to the handheld device 100 to transmit the sensor data from the handheld device 100 to the communication device 112. Figure 2The determining means 108 forms part of the communication device 112 (and not part of the handheld device 100). The determining means 108 is designed to determine information indicative of a property of the substrate 104 based on the transmitted sensor data. Furthermore, the communication device 112 is designed to transmit information to the handheld device 100, while the handheld device 100 is designed to receive information from the communication device 112. Figure 2 , the handheld device 100 is equipped with a communication device 110, which is wirelessly connected to a transmission / reception antenna 176 of a communication device 112, for example, via a transmission / reception antenna 174. The communication between the communication device 112 and the handheld device 100 can be realized wirelessly, that is, via electromagnetic waves 178. The communication device 112 and the handheld device 100 can be connected to each other via a communication network 180, such as the public Internet.

[0096] according to Figure 2 The handheld device 100 and the communication device 112 are designed as independent devices that can be used freely in different locations. The handheld device 100 uses its sensor device 106, for example, Figure 1 The manner shown in FIG. 1 is to determine sensor data that can be used to characterize the properties of substrate 104. However, according to Figure 2 , these sensor data are not evaluated in the handheld device 100 itself. Instead, the sensor data are transmitted wirelessly from the handheld device 100 to the communication device 112. In the communication device 112, the sensor data are evaluated in the determination device 108 arranged there. For this purpose, the determination device 108 of the communication device 112 can also access data sets in the database 120, which are stored in the storage device 118 of the communication device 112 (for example, a hard disk or another electronic mass storage device). The communication device 112 can then wirelessly transmit its conclusions about the properties of the substrate 104 to the handheld device 100. The handheld device 100 can then, for example, use Figure 1 In the manner described in , the operation of the handheld device 100 is controlled or set by means of its control device 122, taking into account the determined properties of the substrate 104. It is also possible that the handheld device 100 then displays corresponding outputs to the user of the handheld device 100 via the user interface 124.

[0097] according to Figure 2, the communication device 112 can be designed, for example, as a central server that can serve a plurality of decentralized handheld devices 100. In this way, a central intelligence and a central database 120 can be provided in the communication device 112, and a plurality of portable handheld devices 100 can be designed in a compact, lightweight and hardware-simple manner. All of these handheld devices 100 can be provided with evaluation logic via a single central server in the form of a communication device 112, for centrally determining the properties of the substrates 104 processed by the handheld devices respectively, based on the sensor data detected decentralized by the handheld devices.

[0098] According to a further preferred embodiment, the structure 126 can be used to ensure that Figure 2 The handheld device 100 shown in FIG. 1 is used to correctly execute the substrate processing plan. Such a plan can be stored in the database 120 of the communication device 112 and thus stored in a central location. In addition, such a plan is useful for operating the handheld device 100 at a decentralized location to process the substrate. Figure 2 The substrate 104 shown in the figure is known to the craftsman. For example, such a plan can prescribe the anchoring scheme of a certain fixing element (for example a screw) for a large number of positions on the substrate 104 in a predefined manner. Due to the communication-enabled connection between the decentralized handheld device 100 and the communication device 112 implemented as a central server, the handheld device 100 can transmit the actual position and type of the fixing element (screw, expansion bolt, etc.) used for this purpose to the communication device 112. Therefore, the handheld device 100 can be designed to transmit information, and the communication device 112 can be designed to receive and store information in a database 120, which archives the process of drilling holes in the substrate 104 and the process of installing the fixing element. By comparing the actual situation (i.e. the data transmitted from the handheld device 100 to the communication device 112) with the nominal situation defined by the installation plan stored in the database 120, it can be ensured that the plan 104 prescribed on the substrate is correctly implemented with the help of the handheld device 100.

[0099] Figure 3 , Figure 4 and Figure 5 A substrate 104 is shown measured in a laboratory, which substrate is processed by means of a handheld device 100. According to an exemplary embodiment of the present invention, the measured substrate 104 is used to populate a database 120 with a data set for correlating properties of the substrate 104 with a characterization of the processing of such substrate 104 using the handheld device 100.

[0100] according to Figure 3A cross-sectional view of a substrate 104 is shown with cavities 116 and a web 190 arranged therebetween. For example, some of the cavities 116 can be filled with insulation 192. The geometry of the substrate 104, for example the extent of the cavities 116, can be measured using a ruler 194 or the like. In addition, a drill hole can be formed in the substrate 104 with the aid of a drill bit 160, and during this process sensor data can be detected. Figure 4 and Figure 5 Other corresponding views are shown.

[0101] according to Figures 3 to 5 For example, a drilling experiment can be performed on the substrate 104. In this case, the sensor data can be detected using the sensor device 106, such as Figure 1 and Figure 2 At the same time, the test substrate 104 can be characterized by measurement technology, for example, information about the arrangement of the cavities 116, the position of the insulating body 192 and the position of the lintel 190 can be assigned to the sensor data. All this information can be used to fill the database 120 with data sets, which can then be used to Figure 1 or Figure 2 The properties of the respective substrate 104 are determined by a database comparison based on the detected sensor data.

[0102] Since the handheld device according to an exemplary embodiment of the invention can be equipped with one or preferably more sensors, the handheld device is particularly suitable for automatic operation, for example when using a robot. According to an exemplary embodiment of the invention, a corresponding robot-assisted operation of the handheld device can be performed, for example, in the following manner:

[0103] The robot moves the handheld device to a predetermined target location on the substrate.

[0104] One or more sensors detect contact of the handheld device with the substrate.

[0105] When contact is detected, a substrate processing process (eg, a drilling process) is performed by the robot.

[0106] At least one sensor detects the achievement of a specified target of a substrate processing process (eg, the achievement of a desired setting depth), thereby triggering the end of the substrate processing process (eg, the setting process).

[0107] Subsequently, the robot moves the handheld device to the next target position (particularly on the same substrate) to perform subsequent substrate processing. In this way, the robot can, for example, perform a predetermined file (for example a drilling file) of a plurality of substrate processing processes when the handheld device is used.

[0108] If a sensor detects the presence of an unsuitable or incorrect substrate for the substrate processing process, in which case the substrate processing process cannot be carried out normally (for example, if a solid concrete substrate is detected when wood screws are to be installed without pre-drilling holes), the substrate processing process can be interrupted, aborted or ended and an error notification can be output optionally.

[0109] In addition, it should be noted that "having" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality. In addition, it should be pointed out that features or steps that have been introduced with reference to one of the above embodiments can also be used in combination with other features or steps of other embodiments described above. Any reference signs in the claims should not be interpreted as limiting.
