Description

Technical Field

[0001] The present invention generally relates to thermal processing systems, and more specifically to systems, methods and apparatus for data communication with laser nozzles of thermal processing systems. Background Technology

[0002] Thermal processing systems, such as laser processing systems, are widely used for heating, cutting, grooving, and marking materials. Currently, operating industrial cutting solutions using laser processing systems relies on highly capable, experienced, and skilled operators diligently setting up, programming, maintaining, and installing consumables within these systems, as well as monitoring them. This is particularly complex and problematic because laser processing systems can operate with a wide variety of consumables (e.g., nozzles), each requiring its own specific settings (e.g., gas, cutting speed, etc.) and having its own lifespan. Due to the numerous options and the complexity of the overall system setup, many problems are often encountered in the field, and errors can occur if the laser processing system's capabilities are not fully utilized.

[0003] For example, consumables used in laser processing systems are typically manually selected and loaded into automated laser consumable changers, and often the wrong consumables are loaded for the desired cutting application. Because the laser processing system is unaware of the consumable's temperature, it cannot detect or react to overheating, which can lead to consumable malfunctions (e.g., nozzle failure) and negative cutting results. Due to the high level of experience and technical expertise required to maintain and set up these laser processing machines, it can be difficult to identify consumables (e.g., nozzles or holders) and their attributes (e.g., malfunction history, damage, identification data, usage history, heat exposure, thermal cycling, and / or brand) for selecting the appropriate consumable to install. Furthermore, there is no data communication between technical specifications (e.g., cutting charts or machine programming processes) and the consumables loaded into the laser processing system. Therefore, laser consumables (e.g., nozzles) are often operated with suboptimal and / or damaging settings intended for different types of consumables.

[0004] In particular, laser nozzles (a type of laser consumable) are designed to be small and lightweight to facilitate mounting to the laser cutting head and allow for rapid movement during operation. However, laser nozzles are frequently exposed to extreme heat loads (e.g., extremely high temperatures) during operation. Therefore, due to overheating conditions and size requirements, it is difficult to commercialize the mounting of data devices with consumable identification, sensors, and / or other data characteristics on laser nozzles.

[0005] Therefore, in order to reduce installation errors and the complexity of laser processing system setup, there is a need for systems and methods that enable the installation and operation of data devices on laser nozzles capable of withstanding harsh operating environments.

[0010] In some embodiments, the data storage element of the signaling device is both readable and writable. In some embodiments, the signaling device is configured to store operating instructions for a thermally processed torch. The operating instructions may be configured to produce altered performance characteristics of the thermally processed torch relative to the original performance characteristics produced by using a laser nozzle without transmitting operating instructions. The operating instructions can be transferred to the thermal processing system via a data transceiver. In some embodiments, the signaling device is spaced approximately 6 inches to approximately 7 feet from the data transceiver. In some embodiments, the data transceiver is integrated into one of a nozzle changer, inspection station, or portable reader.

[0011] In some embodiments, the signaling device includes at least one of a pressure sensor or a strain gauge sensor coupled to or integrated into the nozzle body, and is configured to detect impact shocks in the region where the sensor is located within the laser nozzle. The pressure sensor may be a piezoelectric sensor configured to measure pressure in the region to detect impact shocks. The strain gauge sensor may be configured to measure deformation or strain in the region to detect impact shocks. In some embodiments, the pressure measured by the pressure sensor or the stress value measured by the strain gauge sensor is transmitted to a processor of the laser processing system to detect impact shocks. In some embodiments, the signaling device includes a temperature sensor coupled to or integrated into the nozzle body, and is configured to measure temperature in the region of the laser nozzle where the temperature sensor is located. In some embodiments, the temperature measurement value acquired by the temperature sensor of the signaling device is transmitted to a processor of the laser processing system to detect cutting loss.

[0012] In some embodiments, the thermal conditioning component includes at least one cooling channel located near at least one surface of the signaling device to circulate coolant fluid flow near the signaling device during torch operation. The coolant fluid may be a liquid or a gas. In some embodiments, the at least one cooling channel is configured to thermally condition a region of the laser nozzle remote from the central longitudinal axis. The thermal conditioning region may be radially asymmetrical relative to the central longitudinal axis. In some embodiments, the at least one cooling channel is fluid-separated from the central aperture, such that the flow of coolant fluid through the at least one cooling channel is separated from the fluid flow through the central aperture supporting the laser beam. In some embodiments, the at least one cooling channel is partially defined by at least one surface of the signaling device to achieve direct impact of the coolant fluid on at least one surface.

[0013] In some embodiments, at least one cooling channel includes a plurality of cooling channels forming a cooling manifold disposed between the signal device and the central aperture. In some embodiments, at least one cooling channel includes a plurality of cooling fins disposed in the body of the laser nozzle near the signal device, the cooling fins being configured to guide cooling liquid through them to cool the signal device.

[0014] In some embodiments, at least one cooling channel includes at least one inlet for receiving coolant fluid from a hot-working torch and at least one outlet for discharging coolant fluid from the body of a laser nozzle. In some embodiments, the at least one outlet is positioned radially opposite to the at least one inlet relative to a central longitudinal axis. In some embodiments, at least one cooling channel includes a channel configured to receive coolant fluid from at least one inlet, guide the coolant fluid to flow circumferentially along a central longitudinal axis, and provide coolant fluid to at least one outlet for discharge. In some embodiments, at least one outlet is configured to discharge coolant fluid into either the hot-working torch or the atmosphere.

[0015] In some embodiments, the thermal conditioning component includes a thermally insulating material configured to surround the signal device. At least a portion of the thermally insulating material is disposed between the signal device and a portion of the laser nozzle body. In some embodiments, the thermally insulating material includes a potting compound. In some embodiments, at least a portion of the signal device protrudes from the outer surface of the laser nozzle body and is exposed to the external environment during torch operation. In some embodiments, the thermal conditioning component further includes a shielding element configured to physically block a line-of-sight path between the signal device and the workpiece.

[0016] In some embodiments, the thermal regulation component includes a substantially circumferential channel formed near the proximal end of the body. The circumferential channel is configured to receive coolant fluid.

[0017] In some embodiments, the laser nozzle further includes a nozzle holder configured to connect the body of the laser nozzle to a hot-working torch. The nozzle holder may define a set of coolant ports configured to deliver coolant fluid to the body of the nozzle.

[0032] Figure 1An exemplary data communication network architecture for a laser processing system 100 according to some embodiments of the present invention is illustrated. Within the laser processing system 100, the communication network provides bidirectional data communication between at least one signaling device 104 assigned to a consumable 106 (e.g., a laser nozzle) of a laser processing torch 102 and a processor 110 (e.g., a controller). In some embodiments, the processor 110 includes embedded software / hardware modules for controlling the operation of the torch 102 by, for example, generating a suitable cutting chart and / or nesting procedure for operating the torch 102 based on information obtained from the signaling device 104. The signaling device 104 may be located on the body of the laser nozzle 106 (e.g., coupled to the body) or embedded in the body of the laser nozzle 106 (e.g., integrated with the body). The laser nozzle 106 is then disposed on a cutting head 112 at the end of the torch 102. To facilitate communication between the signaling device 104 and the processor 110, the communication network also includes at least one transceiver 108 for reading data related to the laser nozzle 106 from the signaling device 104, and a consumable identification system 120 for analyzing the data from the transceiver 108 and forwarding the analysis to the processor 110. For example, the consumable identification system 120 can perform consumable identification (e.g., identifying the type of laser nozzle 106 mounted on the cutting torch 102) and recommend suitable system setting parameters / settings for the consumable 106.

[0033] In some embodiments, a communication network enables the various components of the laser processing system 100 to communicate with each other wirelessly and / or via wired connections. This network may be a local area network, such as a LAN, or a wide area network, such as the Internet and / or a cellular network. In some embodiments, the network comprises several discrete networks and / or subnetworks (e.g., cellular-to-Internet) that enable the various components of the laser processing system 100 to communicate with each other.

[0034] As described above, the signal device 104 may be coupled to or integrated into the laser nozzle 106 of the cutting torch 102 to store and transmit information about the nozzle 106. Alternatively, the signal device 104 may be coupled to and / or integrated into a torch component adjacent to the nozzle 106, such as a nozzle holder (not shown) connected to the nozzle 106 within the torch tip 112. For example, the nozzle holder may include a communication channel or cavity for housing the signal device 104 and enabling communication with the transceiver 108. Attaching the signal device 104 to the nozzle holder may be advantageous because this arrangement keeps the delicate communication device away from the tip of the cutting head 112, which is most exposed to the thermal extremes of the cutting process. The signal device 104 attached to the nozzle holder may be encoded with information related to the laser nozzle 106 and / or information related to the nozzle holder. For example, the data encoded on the signal device 104 of the nozzle holder may include the holder's life history and its process data (e.g., temperature exposure), which may be valuable information in addition to the information about the laser nozzle 106. In some embodiments, the nozzle 106 and the nozzle holder are assembled as a coupling pair having common and / or different signal devices 104.

[0035] Figure 2 The invention illustrates some embodiments of the invention with Figure 1An exemplary configuration of a signaling device 104 associated with the laser nozzle 106 of a laser processing system 100 is shown. As illustrated, the signaling device 104 includes a data storage element 202 (e.g., an integrated circuit chip) for storing data. The signaling device 104 may also include an antenna 204 for transmitting data to and / or receiving data from the data storage element 202. The combination of the antenna 204 and the data storage element 202 can form a data tag, such as a radio frequency identification (RFID) tag (e.g., an ultra-high frequency (UHF) RFID tag). The data storage element 202 may be readable and writable. In some embodiments, the data storage element 202 is rewritable, such that it can record new data after an initial data write (e.g., delete or not delete other data present on the data storage element 202). As an example, the data storage element 202 may be rewritten when it is outside the cutting torch 102 (e.g., recording dimensional CTF, quality inspection data, etc. during maintenance of the cutting torch 102 or consumable 106), or when it is inside the cutting torch 102 (e.g., recording temperature data, motion data, etc. during use of the cutting torch 102). In some embodiments, the signaling device 104 includes a detector 208 for detecting the physical characteristics of the corresponding consumable 106 and transmitting the detected information in the form of one or more electrical signals via the antenna 204 of the signaling device 104. The detector 208 may include mechanical features (e.g., features of channels, surfaces, (one or more) critical orifices, appendages, tendrils, deflection features, thermal conductivity, current, capacitance, etc.) for sensing process parameters, such as sensors. For example, the detector 208 may be a temperature sensor for measuring ambient temperature; an accelerometer for measuring the acceleration or rapid deceleration of the dispensed consumable during movement, which can be used to provide feedback on component wear if any oscillations and / or impacts are detected; a gas flow meter for detecting the flow rate of one or more cutting gases; a pressure sensor for detecting impacts, etc. Detailed information regarding the detector 208 of the signaling device 104 is provided below.

[0036] exist Figure 2In some embodiments, the signaling device 104 includes an antenna 204, a data storage element 202 (e.g., an IC chip) for storing consumable data, and at least one detector 208 (e.g., a sensor) for measuring the physical properties of the consumable. This design enhances the functionality and reliability of the allocated consumable 106 (e.g., a laser cutting nozzle) by providing continuous monitoring of key parameters. The integration of the data storage element 202, detector 208, and antenna 204 within the signaling device 104 allows for efficient data collection and transmission, and facilitates better control and maintenance of the laser cutting process. Alternatively, the signaling device 104 may include the antenna 204 and only one of the data storage element 202 or detector 208. In some embodiments, the signaling device 104 includes multiple detectors 208 to measure different physical properties of the allocated consumable 108. In some embodiments, the signaling device 104 includes multiple data storage elements 202 storing different types of data. Generally, these components 202, 208 may serve different functions, such as encryption, sensing, data storage, etc. In some embodiments, detector 208 and / or data storage element 202 can wirelessly communicate with antenna 204 at a distance via a tuning signal path. For example, antenna 204 can be positioned approximately 1 foot away from data storage element 202 and / or detector 208.

[0037] In some embodiments, the data storage element 202 of the signaling device 104 is encoded with information related to the consumable 106 (e.g., a laser nozzle) assigned to the signaling device 104, and this information can be transferred via transceiver 108 to the consumable identification system 120 and / or processor 110 via the antenna 204 of the signaling device 104. For example, if the consumable 106 is a laser nozzle of a laser processing torch 102, the encoded data may be one or more of the following: part number, unique identifier corresponding to one or more unique elements, or a unique combination of cutting parameters corresponding to a unique identifier associated with the laser nozzle 106. The encoded data may also include range and settings for operating the torch 102 compatible with the specific laser nozzle 106 installed, such as data related to one or more of the following: power, gas type and flow rate, focal position, spacing, cutting speed, acceleration / deceleration curve, angle relative to the workpiece, manufacturing data, trademarks, anti-counterfeiting signatures, customizable data associated with other company entities, etc. In some embodiments, the encoded data includes factory inspection and quality assurance data associated with the laser nozzle 106, so that the data can be retrieved subsequently if a problem occurs with the laser nozzle 106. Exemplary factory inspection and quality assurance data include dimensional CTF and physical properties, nozzle data, assembly information, in-situ testing, etc. In some embodiments, coded data includes operating instructions for the cutting torch 102. These operating instructions are adapted to produce altered performance characteristics of the cutting torch 102 relative to the original performance characteristics produced by the cutting torch 102 using the laser nozzle 106 without operating instructions. One such coded instruction may include limiting the focal position and / or beam pattern to closely match the nozzle diameter without allowing excessive clipping. In some embodiments, laser beam settings / conditions, such as gas pressure, flow rate, composition, etc., are adjusted based on data obtained from the laser nozzle 106 via the data storage element 202, indicating the degree of wear, heat load exposure, and / or reduced lifespan on the laser nozzle 106. In some embodiments, torch motion and / or acceleration, etc., are adjusted based on data obtained from the laser nozzle 106 via the data storage element 202, indicating the degree of wear, heat load exposure, and / or reduced lifespan on the laser nozzle 106.

[0038] In some embodiments, at least one detector 208 of the signaling device 104 may be a sensor configured to emit an electrical signal that can be transmitted via antenna 204 of the signaling device 104 to consumable identification system 120 and / or processor 110. In some embodiments, the detector 208 is a pressure sensor for detecting impact shocks at or near the consumable 106 to which the sensor 208 is attached. The pressure sensor 208 may be a piezoelectric sensor configured to measure pressure around the sensor 208, which can be effectively used to detect and measure impact shocks. Specifically, the piezoelectric material of the sensor 208 (e.g., polyvinylidene fluoride (PVDF)) is adapted to generate an electric charge when subjected to mechanical stress or vibration, making it suitable for impact detection. In some embodiments, the pressure sensor 208 adapted to generate a voltage signal upon impact may be attached to any of the laser nozzle 106, laser nozzle holder, or workpiece. The signal emitted by the pressure sensor 208 can be processed and analyzed to determine impact / collision events. For example, the amplitude and frequency of the signal can provide information about the impact force and collision characteristics. Real-time continuous monitoring of the sensor output allows for real-time detection of impacts. This is useful for ensuring the quality of the laser cutting process and preventing damage to equipment or workpieces. Furthermore, data collected from pressure sensor 208 can be analyzed to understand impact dynamics, such as force distribution and / or impact frequency. This information can be used to optimize the quality of the laser cutting process and improve safety.

[0039] In some embodiments, the detector 208 of the signal device 104 is a strain gauge sensor for measuring the impact force experienced by the area where the sensor 208 of the cutting torch 102 is located. For example, the strain gauge sensor 208 may be attached to a nozzle holder (or nozzle 106) at a specific location where deformation is expected during a collision with an object (e.g., a workpiece) to detect deformation or strain on the laser nozzle 106 and / or the laser nozzle holder due to the collision. This detection can be accomplished by the strain gauge sensor 208 measuring the deformation / strain on the laser nozzle 106 and / or the nozzle holder at the time of the collision and by generating an electrical signal proportional to the strain. The electrical signal generated from the strain gauge sensor 208 is amplified and processed by the consumable identification system 120 and / or the processor 110, which can convert the signal into readable data, such as force or stress values ​​used to assess collision dynamics and ensure that the laser cutting process is within safe limits. Generally, the strain gauge sensor 208 can accurately measure the impact force, which in turn allows the laser processing system 100 to make necessary adjustments to improve the cutting process and prevent damage to the equipment or workpiece.

[0040] In some embodiments, the detector 208 of the signaling device 104 is a temperature sensor for measuring the temperature near the location of the cutting torch 102 where the sensor 208 is placed. For example, the temperature sensor 208 may be attached to the laser nozzle 106 or a nozzle holder. The temperature readings read by the temperature sensor 208 may be processed by the consumable identification system 120 and / or the processor 110 to monitor the temperature of the consumable 106 (e.g., the laser nozzle) to which it is attached. This temperature monitoring may be used to detect cut loss, determine and / or predict the wear and remaining life of the consumable 106, predict the suitability of continuing laser processing operations on the consumable 106, etc. For example, when a cut is lost, the rate of temperature rise increases, and the detection of this rate of temperature rise enables the processor 110 to take appropriate and timely actions(one or more), such as alerting the operator or shutting down the laser processing system 100.

[0041] Back Figure 1 The transceiver 108 of the laser processing system 100 is configured to: (i) receive signals transmitted by the antenna 204 of the signaling device 104 (wirelessly or via a wire connected between the transceiver 108 and the antenna 204), (ii) extract coded data transmitted by the signal, and (iii) transmit the extracted data to the consumable identification system 120 and / or the processor 110 (wirelessly or via wired communication) for analysis and further action. In some embodiments, in addition to reading data from the signaling device 104, the transceiver 204 is also a data writing device configured to write to the rewritable data storage element 202 of the signaling device 104 disposed within the cutting torch 102. The transceiver 108 may be located at a distance from the signaling device 104, for example on or within the cutting torch 102 (e.g., on the torch body 114 remote from the cutting head 112), or entirely outside the cutting torch 102. For example, transceiver 108 may be spaced about 6 inches to about 7 feet from signal device 104, such as more than about 1 foot from signal device 104.

[0042] In some embodiments, upon receiving consumable data encoded in signaling device 104 and transmitted by transceiver 108, the consumable identification system 120 of the laser processing system 100 is configured to set processing parameters of the laser processing torch 102, such as cutting speed, assist gas type and pressure, focal position, laser power, etc., wherein these parameters are optimized based on the consumable data obtained from signaling device 104. In some embodiments, the consumable identification system 120 uses at least part of additional data stored in a group of one or more databases 116 to generate identification information and system setting recommendations, the one or more databases 116 including a cutting parameter database and a history database electrically communicating with processor 110 and / or consumable identification system 120. The cutting database 116 may be configured to store recommended parameters for nozzle 106, and the history database 116 may be configured to store a "lifecycle record" of a particular nozzle 106 in use, including events that may degrade performance. By combining stored data from signaling device 104, consumable identification system 120 can use information from two databases 116 (e.g., a historical database and a cutting database) to modify recommended parameter settings for nozzle 106 to improve cutting, such as reducing speed or changing pressure. In some embodiments, data transmitted by signaling device 104 and received by consumable identification system 120 may be stored in one or more of databases 116 for consumable usage tracking and other future references. Database 116 may also store analytical data generated by consumable identification system 120 and / or processor 110. In some embodiments, consumable identification system 120 includes a combination of software and hardware, such as a dedicated computer software instruction set programmed onto a dedicated processor, and may include specifically designated memory locations and / or registers for executing the dedicated computer software instructions.

[0043] In some embodiments, all or a portion of the database 116 is integrated with signal device 104 (e.g., stored in data storage elements of signal device 104), processor 110, and / or consumable identification system 120, or resides on one or more separate, independent computing devices (not shown). In some embodiments, all or a portion of the database 116 is stored in an internet-based cloud storage location 124, which allows components of the laser processing system 100 to access data on demand without maintaining one or more local storage infrastructures. The cloud storage location 124 may be connected to the communication network of the laser processing system 100 via a cloud gateway 126, which may be a hardware device, software application, or a combination thereof. In some embodiments, data used and / or generated by processor 110 and / or consumable identification system 120 may be stored in the cloud storage location 124 via cloud gateway 126.

[0044] The consumable identification system 120 may also be configured to transmit consumable identification information and system setting suggestions to the processor 110, based on which the processor 110 can customize torch operation and settings in a feedback loop. In some embodiments, an interface 122 is provided between the consumable identification system 120 and the processor 110 to facilitate communication between the two components. The interface 122 may include an application programming interface (API) for software integration of the consumable identification system 120 and the processor 110, and / or a configurable fieldbus for facilitating data and control communication between the consumable identification system 120 and the processor 110. In some embodiments, one or more portions of the consumable identification system 120 are integrated with the processor 110, or vice versa.

[0045] In some embodiments, the processor 110 of the laser processing system 100 is configured to control and optimize the operation of the laser processing torch 102 relative to a workpiece (not shown) based on consumable identification information from the consumable identification system 120 and system setting recommendations. The processor 110 can customize a number of system functions, including but not limited to startup sequences, CNC interface functions, gas and operating parameters, and shutdown sequences. For example, based on information received from the consumable identification system 120, the processor 110 can customize for the laser processing torch 102: (i) a cutting chart that provides a specific combination of recommended settings for one or more sets of operating parameters to perform desired torch operations (e.g., cutting a series of parts from a workpiece), and / or (ii) a nesting program that provides a specific sequence of torch operations. In some embodiments, the processor 110 executes one or more artificial intelligence (AI) routines that record process problems such as collisions and cut loss data in real time and use this data in a feedback loop to adjust the parameters of the nesting program to reduce these errors. In some embodiments, the processor 110 enables the automatic delivery of cutting recipes for operating the cutting torch 102, optimized for the laser nozzle 106, based on the laser nozzle identified by the consumable identification system 120. This ensures that the cutting system 100 continues the cutting procedure only when the correct nozzle is loaded onto the cutting head 112, preventing the loading of damaged nozzles (e.g., automatic error prevention), allowing automatic reordering of consumables based on discrete conditions, providing the ability to remotely update and modify cutting schemes and recipes for identified specific nozzles / conditions, and / or alerting operators to nozzle damage, degradation, and / or impairment. In some embodiments, the processor 110 is a digital signal processor (DSP), microprocessor, microcontroller, computer, computer numerical control (CNC) machine tool, programmable logic controller (PLC), application-specific integrated circuit (ASIC), etc.

[0046] In an exemplary embodiment of the communication network of the laser processing system 100, the communication network can be configured to accurately identify the laser nozzle 106 mounted on the laser processing torch 102 using a signaling device 104. The identification information can then be fully utilized by the laser processing system 100 to estimate, monitor, and track gas consumption during torch operation without using any physical gas flow meters. First, the consumable identification system 120 can identify which nozzle 106 is mounted in the cutting head 112 of the laser processing torch 102 during a given operation, based on data stored in the signaling device 104 (which may include an RFID tag). Then, during the same operation, the consumable identification system 120 and / or the processor 110 can continuously or periodically record the gas pressure supplied to the nozzle 106 (e.g., standard process settings) and the cutting height of the laser nozzle 106 relative to the workpiece (e.g., back pressure generated by gas flowing from the distal end of the nozzle 106 and impacting and pushing the workpiece backward). Using the identification information, combined with the gas pressure and cutting height information, the processor 110 can estimate the gas consumption during torch cutting. For example, processor 110 can first find the correct lookup calibration table for the identified nozzle type from a lookup calibration table library, where each table correlates the type / model of the laser nozzle with the theoretical gas consumption of the laser nozzle operating at different cutting heights and gas pressures. Then, for the correctly identified lookup calibration table, processor 110 can use the cutting height and gas pressure data to find a good estimate of the gas consumption. In some embodiments, gas consumption / usage can be accurately determined and / or estimated when gas pressure, flow rate, back pressure, duration, pressure drop, and the cross-sectional area of ​​the nozzle gas flow channel are all known. Consumption estimation can include, but is not limited to, the sum of real-time gas consumption "speed meters" and gas consumption over "odometers" across the feature / part / kit to obtain the total gas usage of the laser processing system 100. This gas consumption monitoring method is advantageous because it eliminates the need for a physical network of expensive and complex gas flow meters installed as part of the gas delivery system to monitor gas pressure and flow rate.

[0047] In some embodiments, in addition to or replacing the signaling device 104 located on the cutting torch 102, the thermal processing system 100 includes at least one sensing device (not shown) located outside the cutting torch 102 for in-situ measurement / sensing of certain physical properties of the cutting torch 102. The external sensing device may be configured to communicate with and / or acquire data from at least one cutting torch consumable 106 (e.g., a laser nozzle) and transmit the data to the consumable identification system 120 and / or processor 110 for processing and analysis. The external sensing device may include one or more of, for example, ultrasonic devices, infrared cameras, strain gauge sensors, chip sensors with read impedance, humidity sensors, visual inspection cameras, etc. The acquired measurement results may include, for example, gas flow / pressure / type, kilowatts / power, speed, focal position, spacing, velocity / acceleration / deceleration, physical and digital properties, manufacturing and quality assurance indicators (e.g., dimensional CTF, surface finish, label testing, and / or other specifications). In some embodiments, the measurement results may be stored in one or more databases 116 (e.g., historical databases) for future reference / tracking.

[0048] In some embodiments, the communication network includes fault detection logic (not shown) for detecting faults in the laser processing system 100 based on data obtained from signaling device 104 and / or data analysis performed by consumable identification system 120 and / or processor 110. The fault detection procedure is adapted to detect errors such as oxidation, poor cut quality, collisions and end-contact, and beam misalignment. In some embodiments, the communication network includes logic for confirming that, for example, the torch consumable 106 of the laser nozzle is in a specific location at a specific time, such as being mounted on torch head 112 during cutting, in a specific location on a nozzle changer (not shown), in a specific inventory location, at an automated tool library / tool ​​boss (not shown), or at an original equipment manufacturer's (OEM) original quality assurance / quality control step, etc. The fault detection logic and / or consumable confirmation logic may be programmed into one or more hardware components and / or one or more software components of the laser processing system 100, for example, programmed into consumable identification system 120 and / or processor 110.

[0049] Figure 3 Some embodiments of the present invention are shown. Figure 1An exemplary embodiment of the laser processing system 100 includes a transceiver 108 configured as a portable handheld reader. A laser nozzle 106 is associated with a signaling device 104, which includes an ultra-high frequency (UHF) RFID tag integrated into or coupled to the body of the nozzle 106. The UHF handheld reader 108 is configured to access / read data stored in the UHF RFID tag on the signaling device 104 at a convenient location, such as when the laser nozzle 106 is in the field, and / or at a convenient time, such as when the laser nozzle 106 is offline (i.e., not in use within the cutting torch). The reader 108 can wirelessly communicate with a consumable identification system 120 and / or a processor 110 to identify attributes associated with the laser nozzle 106, and these attributes can be displayed on a graphical user interface 302 of the reader 108. Exemplary attributes include, but are not limited to, nozzle type, part number, usage history of the laser nozzle 106, and / or whether it is time to replace the laser nozzle 106 and / or nozzle holder.

[0050] According to some embodiments of the present invention, Figure 4 It shows Figure 1 In another exemplary embodiment of the laser processing system 100, the transceiver 108 is configured as a portable handheld reader. As shown, the system 100 includes an array of multiple laser nozzles 106a-106c, each with its own signaling device 104a-104c attached or integrated thereto. The laser nozzles 106a-106c are located offline in a nozzle changer 402. A single transceiver 108, configured as a handheld reader, can perform offline readings of the signaling devices 104a-c to extract attributes associated with the corresponding nozzles in the laser nozzles 106a-106c. The handheld reader 108 can also transmit attribute information to a consumable identification system 120 and / or a processor 110 for planning, analysis, operation, etc. For example, transceiver 108 can facilitate communication between signaling devices 104a-104c and consumable identification system 120 and / or processor 110 to determine nozzle type, nozzle usage history, cutting operation information associated with the nozzle (e.g., nesting selection, cutting chart selection, etc.), and to identify and confirm the specific location of nozzles 106a-106c in nozzle changer 402 using the fault detection logic described above. This information can be displayed to the user via graphical user interface 302 of reader 108.

[0051] like Figure 3 and Figure 4As shown, the transceiver 108, in the form of a handheld reader, represents a portable, stand-alone component in the laser processing system 100 for reading data stored on one or more signal devices 104. Alternatively, the transceiver 108 may be attached to or integrated into the cutting head 112 of the torch 102, close to the nozzle 106 and / or nozzle holder when mounted on the torch 102, thereby maintaining a relatively short communication distance with the laser nozzle 106 and / or nozzle holder during torch cutting operations. In some embodiments, the transceiver 108 is attached to or integrated into the nozzle holder. In some embodiments, the transceiver 108 is attached to or integrated into the nozzle changer 402 or another component of the laser processing system 100 external to the torch 102, such as an inspection station (not shown). In some embodiments, each signal device 104 includes an RFID tag, and the transceiver 108 additionally functions as an RFID writer configured to write to the signal device 104 based on data received from the processor 110. As an example, integrating the read / write RFID system with the processor at the checkpoint can greatly improve the accuracy, functionality, and operation of the laser processing system 100.

[0052] On the other hand, the laser nozzle 106 of the laser processing torch 102 can be designed to include one or more physical features for protecting the signaling device 104 coupled to or integrated into the laser nozzle body, for example, from the extreme thermal loads (e.g., very high temperatures) generated during laser processing operations. This is because the thermal loads experienced by the laser nozzles during torch operation pose a significant challenge to the lifespan and operation of communication devices associated with these laser nozzles. Therefore, embodiments of the invention include one or more thermal conditioning, insulation, and protection devices configured to insulate and / or shield the signaling device 104 from exposure to the extreme temperatures and debris generated by industrial cutting laser torch operations.

[0053] In some embodiments, the laser nozzle 106 of the present invention includes a thermal conditioning component coupled to or integrated into the body of the laser nozzle 106 or a laser holder. The thermal conditioning component may be located near the signaling device 104 to provide cooling for one or more components of the signaling device 104 (e.g., data storage element 202, antenna 204, and / or detector 208) during torch operation, thereby enabling data stored in the data storage element 202 and / or signals emitted by the detector 208 to be read by the data transceiver 108 during torch operation, which typically involves high heat loads. In some embodiments, the thermal conditioning component is a recess in the signaling device 104 or a metal shield (e.g., a flange or protrusion) that deflects molten material, thereby physically protecting the signaling device 104. In other embodiments, the thermal conditioning component is a separate mounting of the nozzle 106 or nozzle holder, which includes one or more of the following: cooling channels or surfaces, insulating features (e.g., thermal shields), isolation features from the metal nozzle body, active cooling features from the nozzle holder, active cooling via direct impact to the signaling device 104 or adjacent channels, and / or gas or liquid cooling. In some embodiments, the signal device 104 is mounted to the nozzle via an insulator, such as an insulating mounting device, and one or more flow channels from the nozzle cavity to the signal device 104 serve as a dual nozzle, such that the flow channels draw some airflow from the central orifice to thermally regulate / cool the signal device 104. Details and examples of thermal regulation of the laser nozzle 106 including the signal device 104 are described below.

[0054] Figure 5a and Figure 5b Some embodiments of the invention are shown for protecting the signal device 514 from heat exposure during torch operation. Figure 1 Perspective and partial hidden-line views of an exemplary design of a laser nozzle 106 are shown. As shown, the laser nozzle 106 includes a body defining a central aperture 502 extending along a central longitudinal axis A of the body from a proximal end 504 to a distal end 506. The distal end 506 is defined as the end of the nozzle body closest to the workpiece (not shown) during torch operation, with the proximal end 504 opposite the distal end 506 along the longitudinal axis A. The central aperture 502 has an exit aperture 508 and is configured to conduct a laser beam to the workpiece via the exit aperture 508 for processing the workpiece in a laser processing operation. In some embodiments, the laser beam generates at least about 2,000 watts of power when used to process the workpiece. In some embodiments, the laser beam generates at least about 6,000 watts of power when used to process the workpiece.

[0055] Signal device 514 includes the same as described above. Figure 1 and Figure 2 The signal device 104, described in detail, has the same characteristics and can be connected to or integrated into the body of the laser nozzle 106. Figure 5a and 5b In one embodiment, the signal device 514 is substantially cuboid in shape and defines a central longitudinal axis B. During assembly, the signal device 514 may be arranged asymmetrically relative to the central longitudinal axis A of the nozzle body. Specifically, the central longitudinal axis B of the signal device 514 may be positioned perpendicular to the longitudinal axis A of the nozzle body. In an alternative embodiment, when the signal device 514 is attached to (or integrated into) the nozzle body, the central longitudinal axis B of the signal device 514 may be oriented coaxially with but offset from the longitudinal axis A of the nozzle 106.

[0056] The thermal conditioning component 510 may also be coupled to or integrated into the body of the laser nozzle 106 to provide insulation and / or cooling for the asymmetric cuboid signal device 514. The thermal conditioning component 510 may be an area filled with a thermally insulating material (e.g., potting compound) 511 that physically contacts at least a portion of the signal device 514. The thermally insulating material 511 may be disposed between the signal device 514 and a portion of the body of the laser nozzle 106 to provide thermal conditioning for the signal device 514. As an example, the thermal conditioning component 510 may be an encapsulation surrounding the signal device 514, wherein the encapsulation is filled with the thermally insulating material 511 surrounding at least a portion of the signal device 514 disposed therein. The encapsulation may be such that at least a portion of it protrudes from the outer surface of the body of the laser nozzle 106 and is exposed to the external environment during torch operation. Alternatively, the encapsulation may be recessed within the body of the laser nozzle 106 to prevent the signal device 514 from being exposed to the outside.

[0057] Figure 6a and 6b The invention illustrates methods for protecting signaling devices from heat exposure during torch operation, according to some embodiments thereof. Figure 1 A side view and perspective partial hidden line view of another exemplary design of a laser nozzle. Figure 6a A nozzle design with a signal device 614 is shown, which is coupled to or integrated into the nozzle; and Figure 6b The same design without signal device 614 is shown to better visualize the thermal regulation component 610 that provides thermal protection for signal device 614. Signal device 614 can be used with... Figure 5a and 5b The asymmetrical cuboid signal device 514 is basically the same. The nozzle body can be... Figure 5a and 5b The nozzle bodies are basically the same.

[0058] Figure 6a and 6b The heat regulation component 610 can be with Figure 5a and 5bThe thermal conditioning component 510 is substantially the same (e.g., having an area filled with thermal insulation material 604 that is in physical contact with at least a portion of the signaling device 614), but differs in that it incorporates an active localized cooling element in the form of a group of one or more cooling channels 602. The group of one or more cooling channels 602 may be located near at least one surface of the signaling device 614 to circulate coolant fluid around the signaling device 614 during torch operation. For example, one or more cooling channels 602 may be embedded in the thermal insulation material 604 of the thermal conditioning component 610 and physically contact the signaling device 614 to provide direct cooling or be close to the signaling device 614 to provide indirect cooling. The coolant fluid guided through the cooling channels 602 may be a liquid or a gas. In an alternative embodiment, the thermal conditioning component 610 includes only the group of cooling channels 602 and does not include the thermal insulation material 604.

[0059] like Figure 6a and 6b As shown, a set of cooling channels 602 is located behind the signal device 614, i.e., between the signal device 614 and the nozzle body (central longitudinal axis A and / or the laser beam). The set of cooling channels 602 may include an axial inlet section 602a (parallel to the central longitudinal axis A of the nozzle body) configured to direct coolant fluid to the signal device 614, a radial section 602b (e.g., at or near the surface of the signal device 614) configured to conduct coolant fluid along the longitudinal axis B of the signal device 614, and an axial outlet section 602c configured to divert heated coolant fluid from the signal device 614 to ultimately exit from the laser nozzle 106. In the case of direct cooling, the radial cooling channel 602b may be partially defined by at least one surface of the signal device 614 to achieve direct impact of the coolant fluid on that surface. Since a set of cooling channels 602 is localized to the signal device 614, and is radially asymmetrical and located away from the central longitudinal axis A of the nozzle body, the area thermally regulated by the cooling channels 602 is also radially asymmetrical and located away from the central longitudinal axis A. In some embodiments, the set of cooling channels 602 is fluidly separated from the central hole 502 of the laser nozzle 106, such that the flow of coolant fluid through the cooling channels 602 is separated from the fluid flow through the central hole 502 supporting the laser beam.

[0060] Figures 7a to 7c The invention illustrates methods for protecting signaling devices from heat exposure during torch operation, according to some embodiments thereof. Figure 1 Another exemplary design of the laser nozzle 106 is shown in perspective and side view partial hidden line views. Figure 7a A nozzle design with a signal device 714 is shown, which is coupled to or integrated into the nozzle; and Figure 7bThe same design without signal device 714 is shown to better visualize the thermal regulation assembly 710 that provides thermal protection for signal device 714; and Figure 7c This shows Figure 7a Outline view of the design. Signal device 714 can be used with... Figure 5a and 5b The asymmetrical cuboid signal device 514 is basically the same. The nozzle body can be... Figure 5a and 5b The nozzle bodies are basically the same.

[0061] Figures 7a to 7c The heat regulation component 710 can be with Figure 5a and 5b The thermal regulation component 510 is essentially the same (e.g., having an area filled with thermally insulating material 704, which is in physical contact with at least a portion of the signal device 714), the difference being the addition of an active localized cooling element in the form of a cooling manifold 702. The cooling manifold 702 can be coupled to or integrated into the body of the laser nozzle 106. Figure 7c As shown, thermal insulation material 704 can be located on the proximal and distal surfaces of the signal device 714, while cooling manifold 702 can be located behind the signal device 714 and physically communicate with the side surfaces of the signal device 714 to provide shock cooling on the side surfaces of the signal device 714. Therefore, cooling manifold 702 is disposed between the signal device 714 and the central hole 502 of the laser nozzle 106. In some embodiments, cooling manifold 702 can be configured to provide shock cooling on multiple surfaces of the signal device 714. Figure 7b and 7c As shown, the cooling manifold 702 includes two channels 702a and 702b, wherein channel 702a is configured to direct coolant fluid to the signal device 714 to cool the signal device 714, while channel 702b is configured to divert the generated warm coolant fluid away from the signal device 714. In some embodiments, such as Figure 7c As shown, channel 702a is configured with a tortuous / winding flow pattern to promote high-speed flow that enhances heat transfer. Furthermore, as... Figure 7c As shown in the embodiment, channels 702a and 702b combine to form a generally serpentine coolant flow pattern between the central longitudinal axis A (e.g., the laser beam) of the laser nozzle 106 and the signal device 714. The coolant flow is first delivered axially distally in the cooling channel and then gradually advanced backward toward the proximal end of the laser nozzle 106.

[0062] Figures 8a to 8d Some embodiments of the invention are shown for protecting the signal device 814 from heat exposure during torch operation. Figure 1Side view, dashed side view, perspective view, and dashed perspective view of another exemplary design of the laser nozzle 106. Signal device 814 can be used with... Figure 5a and 5b The asymmetrical cuboid signal device 514 is basically the same. The nozzle body can be... Figure 5a and 5b The nozzle bodies are basically the same.

[0063] Figures 8a to 8d The design includes a thermally modulating component 810 in the form of a group of one or more cooling fins disposed within the body of the laser nozzle 106 adjacent to the signal device 814 (e.g., through etching, machining, additive manufacturing, etc.). The cooling fins 810 form channels configured to guide coolant fluid through which active cooling is achieved, thereby cooling the signal device 814, isolating the signal device 814 from axis A / away from the heat source, and / or enhancing the active cooling of features of the laser nozzle 106 directly supporting the signal device 814, such as the cooling fins 810. Figure 8a and 8b As shown, a set of cooling fins 810 form recesses for receiving signal devices 814, such that channels formed by the fins 810 directly communicate with multiple surfaces of the signal devices 814 to provide shock cooling on these surfaces. Specifically, as... Figure 8b As shown, fin 810 creates a cooling path 822 that guides coolant fluid along the side surface 816 of the signal device 814 and along the proximal surface 818 and distal surface 820 of the signal device 814 to provide simultaneous thermal conditioning of multiple surfaces during the cutting operation.

[0064] like Figure 8c and 8d As shown, coolant fluid enters fin 810 via inlets 824 through channels formed in fin 810. The coolant fluid is adapted to flow through these channels, which are generally arranged around and adjacent to signal device 814 (e.g., above surfaces 816, 818, and 820 of signal device 814), and through which it thermally conditions fin 810, before exiting from the side of nozzle 106 via outlets (not shown). The outlets may be configured as vents on the side of nozzle 106 to allow the heated coolant fluid to dissipate into the surrounding environment. Generally, the presence and position of fins 810 around signal device 814 are adapted to increase the surface area of ​​signal device exposed to the coolant flow, thereby increasing the cooling experienced by signal device 104 and thus insulating it from the extreme thermal load of laser nozzle 106 during torch operation.

[0065] Figure 9a and 9b Some embodiments of the invention are shown for protecting the signal device 914 from heat exposure during torch operation. Figure 1 A perspective view and a cross-sectional view of another exemplary design of the laser nozzle 106. The laser nozzle 106 can be used with... Figure 5a and 5b The nozzles are basically similar. (Including the references above) Figure 2 The signal device 914 of the components described in the detailed description (e.g., antenna 203, data storage device 202, and / or detector 208) can be coupled to or integrated into the body of the laser nozzle 106. Figure 9a and 9b In this embodiment, the signal device 914 is circular / annular. During assembly, the signal device 914 is arranged radially symmetrically (i.e. circumferentially) around the central hole 502 and the central longitudinal axis A of the nozzle body.

[0066] As shown, the thermal conditioning component 910 may be coupled to or integrated into the body of the laser nozzle 106 to provide thermal isolation for the symmetrical annular signal device 914. Specifically, the thermal conditioning component 910 may be a circular channel 916 filled with a thermally insulating material (e.g., potting compound) 918, in which the signal device 914 is disposed. The thermally insulating material 918 may surround and physically contact one or more surfaces of the signal device 914 within the channel 916 to provide thermal conditioning and / or insulation for the signal device 914 therein. As an example, the thermal conditioning component 910 may be an encapsulation surrounding the signal device 914, wherein the encapsulation is filled on multiple sides with the thermally insulating material 918 surrounding the signal device 914. In some embodiments, the thermal conditioning component 910, together with the signal device 914, is located near the proximal end 504 of the laser nozzle 106 to be away from the cutting process and insulated by both the nozzle 106 itself and the insulating material 918.

[0067] Figures 10a and 10b respectively illustrate methods for protecting the signal device 1014 from heat exposure during torch operation according to some embodiments of the present invention. Figure 1 Perspective and sectional views of another exemplary design of the laser nozzle 106. The signal device 1014 can be used with...

As shown in the figure, the symmetrical annular signal device 1014 is located near the proximal end 504 of the laser nozzle 106.

[0068] A thermal adjustment component 1010 is coupled to (or integrated into) the body of the laser nozzle 106 to thermally adjust the signal device 1014. In the embodiments of Figures 10a and 10b, the thermal adjustment component 1010 can be coupled to... Figure 9a and 9bThe heat regulation component 910 is substantially the same (e.g., having a circular channel 1016 filled with a thermally insulating material 1018 that is in physical contact with at least a portion of the signal device 1014 disposed therein), except that a set of cooling fins 1020 is added, which are circumferentially distributed around the annular signal device 1014 along at least the inner diameter of the channel 1016 between the channel 1016 (including the signal device 1014) and the aperture 502 of the laser nozzle 106. In some embodiments, the inner and / or outer sidewalls of the channel 1016 are etched to form the cooling fins 1020. As shown, parallel cooling channels can be formed by pairs of adjacent cooling fins 1020, wherein the cooling channels are uniformly distributed circumferentially around the annular signal device 1014 to provide uniform cooling of the signal device 1014.

[0069] Figure 10b An active coolant flow path 1022 is shown through the cooling fins 1020 of the thermal conditioning unit 1010 during laser torch operation. As shown, coolant fluid (e.g., cooling gas, cooling liquid, cooling mist, etc.) is supplied via inlets formed by channels distributed around the inner diameter of the channel 1016 by the cooling fins 1020. The coolant fluid is adapted to flow axially through these channels in laminar and / or turbulent modes and to exit the channels outward away from the laser nozzle 106 and signal device 1014, guided by the curved shape of the channels / fins 1020. This thermal conditioning configuration is adapted to avoid interference and / or influence on the cutting results at the distal end 506 of the nozzle 106 by guiding the heated coolant fluid outward away from the signal device 1014. Furthermore, since the channels of the cooling fins 1020 are located at and / or near one or more surfaces of the signal device 1014 (e.g., along one side surface and distal surface of the signal device 1014, such as...), Figure 10b As shown, they provide uniform and close-proximity cooling for the signal device 1014. Overall, the radially symmetrical thermal conditioning components 1010 include circular channels 1016, potting material 1018, and circumferentially arranged cooling fins 1020, which work together to achieve substantially uniform cooling for the signal device 1014.

[0070] Figures 11a to 11c Some embodiments of the invention are shown for protecting the signal device 1114 from heat exposure during torch operation. Figure 1 Perspective view, sectional view, and partially cut-away end view of another exemplary design of the laser nozzle 106. The signal device 1014 can be used with...

As shown in the figure, the symmetrical annular signal device 1114 is located near the proximal end 504 of the laser nozzle 106.

[0071] The thermal adjustment component 1110 is connected to (or integrated into) the body of the laser nozzle 106 to thermally adjust the signal device 1114. Figures 11a to 11c In one embodiment, the thermal regulation component 1110 can be coupled with Figure 9a and 9b The heat regulation component 910 is substantially the same (e.g., having a circular channel 1116 filled with thermally insulating material 1117, which is in physical contact with at least a portion of the signal device 1114 disposed therein), except that an annular cooling channel 1118 is added on or near the distal surface 1102 of the signal device 1114. The annular cooling channel 1118 may be formed near the proximal end 504 of the nozzle body and configured to circulate coolant fluid within the laser nozzle 106 and across a portion of the distal surface 1102 of the signal device 1114 and / or the thermally insulating material 1117. As shown, the annular cooling channel 1118 has an inlet 1120 and an outlet 1122, which are arranged generally radially opposite each other around the circumference of the nozzle 106, both of which may be located near the inner diameter of the channel 1116.

[0072] Figure 11b and 11c An active coolant fluid flow path 1124 is shown for the annular cooling channel 1118 of the thermal conditioning unit 1010 during laser torch operation. As shown, coolant fluid (e.g., cooling gas, cooling liquid, cooling spray, etc.) is axially introduced into the cooling channel 1118 in the distal direction via inlet 1120. The coolant fluid is adapted to flow axially through the signal device 1114 (e.g., between a side surface 1102 of the signal device 1114 and the nozzle body) to enter the annular cooling channel 1118. The coolant fluid then flows circumferentially within the annular cooling channel 1118 between the distal surface 1102 of the signal device 1114 and the nozzle body, and then reaches the outlet 1122, which is radially positioned opposite to the inlet 1120, for discharge. The heated coolant fluid is then axially discharged in the proximal direction through the outlet 1122. The discharged coolant fluid may be discharged from the nozzle 106 into a mating component (not shown) of the hot-working torch or discharged into the atmosphere via the gap between the nozzle 106 and the mating component. Figures 11a to 11c Only one inlet 1120 and one outlet 1122 are shown, but those skilled in the art will understand that there can be any number of inlets and outlets. Figure 11c The circumferential flow path 1124 of the coolant fluid within the annular cooling channel 1118 is highlighted. As shown, this portion of the flow path 1124 radially surrounds the orifice 502 and axially lies between the body of the signal device 1104 and the nozzle 106.

[0073] Figure 12The attachment according to some embodiments of the present invention is shown. Figure 1 A cross-sectional view of the nozzle holder 1200 of the laser nozzle 106, designed to protect the signaling device within the nozzle from heat exposure during torch operation. The signaling device 1214 can be connected to... Figure 9a and 9b The symmetrical ring signal device 914 is basically the same. The nozzle can be... Figure 5a and 5b The nozzle 106 is substantially the same. As shown, a symmetrical annular signal device 1214 is circumferentially disposed near the proximal end 504 of the laser nozzle 106 around the nozzle orifice 502. In some embodiments, the signal device 1214 is located within the nozzle body such that the proximal surface 1202 of the signal device 1214 is exposed when the nozzle 106 is not installed. The nozzle holder 1200 has a body defining a central longitudinal axis A that extends between the proximal end 1204 and the distal end 1206, wherein the distal end 1206 is configured to attach to the proximal end 504 of the laser nozzle 106 to connect the body of the laser nozzle 106 to the remainder of the thermal cutting torch. More specifically, the distal end 1206 of the nozzle holder 1200 is shaped to be complementary to the proximal end 504 of the body of the laser nozzle 106 to form an interface 1208 therebetween. Furthermore, the nozzle holder 1200 includes a central hole 1207 disposed around the central longitudinal axis A.

[0074] exist Figure 12 In one embodiment, the thermal regulation component 1210 is coupled to (or integrated into) the body of the nozzle holder 1200 to thermally regulate the signal device 1214 disposed in (or integrated into) the nozzle 106. In this embodiment, the thermal regulation component 1210 includes a set of coolant ports and coolant flow channels defined within the nozzle holder 1200, which will be described in detail below. These ports and channels cooperatively deliver coolant fluid to an interface 1208 near the signal device 1214 embedded in the nozzle 106, for example, above the proximal surface 1202 of the signal device 1214. Figure 12 In this embodiment, the thermal regulation component 1210 is located only in the nozzle holder 1200, the coolant fluid does not enter the nozzle 106, and there is no need to provide special thermal regulation features in the laser nozzle 106 itself. Alternatively, a portion of the thermal regulation component 1210 may be distributed between the nozzle holder 1200 and the nozzle 106 to cooperate in cooling the signal device 1214.

[0075] like Figure 12As shown, the heat-regulating component 1210 of the nozzle holder 1200 includes a set of axial holes 1212 formed (e.g., drilled) in the body of the nozzle holder 1200 and circumferentially distributed around a central hole 1207, wherein the inlets of these axial holes 1212 are located on the proximal surface 1204 of the nozzle holder 1200. The heat-regulating component 1210 also includes an annular groove 1216 located at the distal end 1206 of the nozzle holder 1200 and formed along the interface 1208 between the nozzle holder 1200 and the nozzle 106. The annular groove 1216 extending around the central hole 1207 is in fluid communication with the axial holes 1212. During active cooling, coolant fluid is supplied to the axial holes 1212 via their respective inlets, the coolant fluid being adapted to flow axially from the axial holes 1212 in the distal direction toward an outlet of the axial holes 1212 in fluid communication with the annular groove 1216. Upon entering the annular groove 1216, the annular groove 1216 is configured to guide coolant fluid radially outward to discharge coolant fluid from the component, while simultaneously contacting and cooling the proximal surface 1202 of the signal device 1214 located at the interface 1208. In some embodiments, the annular groove 1216 is configured to allow coolant fluid to flow near the signal device 1214 and discharge from the side of the component without entering the laser nozzle 106 itself, thereby avoiding manufacturing complexities in the design of the laser nozzle 106. In some embodiments, the cooling features of the thermal conditioning component 1210 of the nozzle holder 1200 (e.g., the offset orifice 1212, the slot forming the annular groove 1208, etc.) are formed of a ceramic material.

[0076] Figure 13 An exemplary process 1300 for thermally modulating a signal device coupled to or integrated into the body of a laser nozzle 106, according to some embodiments of the present invention, is illustrated. Figure 1 The laser cutting system 100 is associated with and adopts Figures 5a to 12 One or more thermal regulation designs. The signal device can be radially symmetrical (e.g., annular) and circumferentially arranged around the central longitudinal axis of the body of the nozzle 106 (e.g., signal device 1014 of Figures 10a and 10b). Figures 11a to 11c Signal device 1114 Figure 12 The signal device 1214. Alternatively, the signal device may be radially asymmetrical (e.g., cuboid) and asymmetrically arranged with respect to the central longitudinal axis of the body of the nozzle 106 (e.g., respectively). Figure 6a and 6b Signal device 614, signal device 714 in Figures 7A to 7c Figures 8a to 8d Signal device 814). Thermal regulation components (e.g., as mentioned above). Figures 5a to 12 The described thermal adjustment component can be coupled to or integrated into the body of the nozzle 106 to provide thermal protection for the signal device. The thermal adjustment component can be as described above. Figures 5a to 12Any of the described thermal adjustment components, and / or suitably adapted (e.g., combined and matched) to be compatible with the shape and / or position of the signaling device.

[0077] Process 1300 begins at step 1302 by guiding fluid through the central hole 502 of the body of the laser nozzle 106 of the torch 102 along the central longitudinal axis A of the nozzle body to initiate the operation of the laser cutting torch 102, in order to support the conduction of the laser beam through the central hole 502.

[0078] At step 1304, the thermal adjustment component can be configured as described above. Figures 5a to 12 One or more devices described herein cool signaling devices associated with the laser nozzle 106 during torch operation. As will be fully understood by those skilled in the art, the above references... Figures 5a to 12 Various embodiments of the described thermal regulation components can be readily combined, matched, or otherwise adapted to provide thermal protection for signaling devices of different shapes. For example, the thermal regulation component can be designed to include a group of one or more cooling channels located near at least one surface of the signaling device. This group of cooling channels can guide coolant fluid through which radially asymmetrical signaling devices (e.g., respectively) are thermally regulated. Figure 6a and 6b cuboid signal device 614 Figures 7a to 7c cuboid signal device 714 Figures 8a to 8d (a rectangular signal device 814) or a radially symmetrical signal device (the ring signal device 1014 in Figures 10a and 10b). Figures 11a to 11c Ring signal device 1114 Figure 12 The annular signal device 1214). For example, guiding the coolant fluid through this set of cooling channels may include allowing the coolant fluid to directly impact at least one surface of the signal device or cool an area close to the signal device. The set of cooling channels may include at least one inlet for receiving coolant fluid for cooling the signal device and at least one outlet for discharging the heated coolant fluid from the signal device back to the torch head and / or the atmosphere. The set of cooling channels may be a manifold (e.g., Figures 7a to 7b ), a set of cooling fins (e.g.) Figures 8a to 8d (Figures 10a and 10b) and / or designed to circulate coolant fluid circumferentially and / or axially (relative to the longitudinal axis A of the nozzle body) near the signaling device to cool and / or insulate the cooling channels of the signaling device (e.g., Figure 11a and 11b , Figure 12 In the form of a nozzle 106, nozzle holder 1200, or a combination of both, the heat-regulating component may be coupled to (or integrated into) the nozzle 106, nozzle holder 1200, or a combination of both. In some embodiments, in addition to or instead of the cooling channel, the heat-regulating component may include thermally insulating material to cool the signaling device (e.g., Figure 5a and5b , Figure 9a and 9b In some embodiments, in addition to or instead of cooling channels and / or thermal insulation material, the thermal conditioning component may include a shielding element configured to physically block the line-of-sight path between the signal device and the workpiece. In some embodiments, the thermal conditioning component is fluid-separated from the central orifice of the laser nozzle, such that the coolant fluid and / or thermal insulation material of the thermal conditioning component are separated from the fluid in the central orifice without mixing.

[0079] At step 1306, the laser cutting torch 102 is adapted to process (e.g., cut) a workpiece by delivering a laser beam to it. Because the thermal conditioning components are configured to protect the signaling device from heat load during torch operation, the transceiver 108, located outside the cutting head 112 of the torch 102, is able to successfully read from the data storage unit 202 of the signaling device during torch operation at step 1308. In some embodiments, the transceiver 108 also writes data to the data storage unit 202 of the signaling device during the same torch operation. The transceiver 108 may be located outside the torch 102 (e.g., more than about one foot from the body of the nozzle 106), for example, integrated with one of a nozzle changer, inspection station, or portable reader.

[0080] Generally, the present invention relates to coupling or integrating signaling devices to a laser nozzle or nozzle holder, which offers several advantages, including simplifying the laser cutting system 100 by eliminating the need for integration with the laser head 112 or upstream components when the transceiver 108 is located at a distance outside the cutting torch 102. This simplification can be enhanced when the system 100 is configured to read data from or write data to multiple signaling devices substantially simultaneously at a distance. Furthermore, the invention is characterized by various designs (e.g., cooling features and devices) that reduce and / or mitigate overheating of the signaling devices within the laser cutting nozzle during torch operation and prevent thermal damage to them. Additionally, the invention allows for the automatic delivery of optimized cutting recipes from the processor 110 to the cutting torch 102 based on information stored in a signaling device associated with at least one consumable of the cutting torch 102, such as consumable brand / source identification information, consumable type, consumable status, etc. The processor 110 can use this information to tailor the cutting recipe to minimize human error and improve the resulting cut quality.

[0081] It should be understood that various aspects and embodiments of the present invention can be combined in various ways. Based on the teachings of this specification, those skilled in the art can readily determine how to combine these various embodiments. Modifications may also be made by those skilled in the art after reading this specification.
