Description

Technical Field

[0001] The present invention relates to the technical field of mining drill bit repair, and particularly relates to an on-line repair device for mining blast hole drill bits. Background Art

[0002] In the contemporary industrial system architecture, the mining industry, as a fundamental and pillar industry for resource extraction, plays an indispensable supporting role in the global economic development with its stable and efficient operation. In the complex production process of the mining industry, the drilling operation, as a key precondition for the blasting operation, directly determines whether the subsequent mining work can be carried out smoothly with its operation efficiency and quality.

[0003] With the rapid development of the global economy, the demand for mineral resources in various industries shows a continuous growth trend, which prompts the mining industry to continuously expand its mining scale. During the mining operation, the blast hole drill bit, as a key tool, is in a high-load and extremely harsh working environment for a long time. Due to the combined effects of multiple factors such as intense friction, strong impact, high temperature and high pressure from the rock, the drill bit is extremely prone to damage phenomena such as wear, chipping, and deformation. According to the authoritative industry statistics, in the large open-pit coal mine mining operation, the blast hole drill bits equipped for each drill rig need to be repaired or replaced 2 to 3 times per week on average; while in the underground metal mine mining, due to the more complex working environment, the loss frequency of the drill bits is higher, and the average service life of the drill bits in some mining areas is even less than one week.

[0004] The existing repair methods have the following deficiencies:

[0005] 1. The first method is to remove the damaged drill bit from the drill rig and transport it to a professional repair workshop for repair. This process involves multiple complex operational links and requires a large amount of human, material, and time costs. First of all, removing the drill bit requires professional technicians to use various special tools to carefully disassemble it from the complex-structured drill rig equipment under the premise of ensuring safety. This operation is not only time-consuming and laborious but also requires extremely high professional skills and experience from the technicians. Once an operation error occurs, it is very likely to cause secondary damage to the drill rig. Secondly, the transportation link cannot be ignored. Since the repair workshop is usually at a certain distance from the mining area, special transportation vehicles need to be used to safely transport the drill bit to the destination. During transportation, the drill bit also needs to be properly protected and fixed to avoid further damage under bumpy road conditions. After arriving at the repair workshop, the drill bit also needs to go through a series of processes such as queuing for repair, repair operations, and quality inspection after repair. The entire process often takes several days or even weeks. During this period, the drill rig is forced to stop due to the lack of a drill bit, resulting in the stagnation of mining operations. For example, in a large metal mine, the average downtime caused by sending the drill bit for repair each time is up to 8 days, and the direct economic loss caused every day is as high as hundreds of thousands of yuan, while the indirect losses are even immeasurable, including losses in market share due to production plan delays and contract default risks, etc.

[0006] 2. The second traditional method is to directly replace the drill bit with a brand-new one. This seemingly simple and direct approach actually hides huge cost risks. The procurement price of brand-new drill bits is usually relatively expensive, especially for some high-end drill bits that use special materials and advanced manufacturing processes and can adapt to harsh mining environments. Their unit prices are even higher. Frequent replacement of brand-new drill bits will cause the enterprise's operating costs to show a linear upward trend. Take a non-ferrous metal mine as an example. The annual expenditure of this mine on drill bit procurement is as high as tens of millions of yuan, and a large part of this cost is due to over-reliance on replacing new drill bits rather than effectively repairing old drill bits. This high-cost repair strategy not only brings a heavy burden to the enterprise's financial situation but also causes great waste of resources, running counter to the current concept of green development and circular economy.

[0007] In summary, traditional drill bit repair methods are no longer able to meet the requirements of modern mining for efficient and low-cost production. Developing a technology that can perform on-line repair of blast hole drill bits in real-time, efficiently, and accurately at the mining site has become an urgent need for the mining industry to achieve technological upgrading and sustainable development.

[0024] Advantages of the present invention:

[0025] 1. Multi-dimensional Precision Detection and Intelligent Decision-making Repair System: The present invention innovatively integrates 3D scanning technology with cutting-edge large model data analysis technology. Before the repair operation, 3D scanning technology is used to conduct all-round and high-resolution data acquisition on the worn mining blast hole drill bit, accurately obtaining multi-dimensional detailed data such as the wear morphology, size changes, and material loss of the drill bit. Subsequently, with the powerful data analysis and learning capabilities of the large model, the damage type, degree, and potential fault hazards of the drill bit are quickly and accurately identified. Based on these precise analysis results, the system automatically generates the optimal repair plan for the drill bit, covering various aspects such as repair process selection, repair material adaptation, and repair parameter setting. Compared with traditional repair methods, this system can more accurately locate the repair position, avoid over-repair or under-repair situations, greatly saving repair time. Through comparison and verification in actual application scenarios, when using this system for drill bit repair, the average repair time can be shortened by about 40%. At the same time, during the repair process, through real-time monitoring and intelligent feedback adjustment of each link of the repair process, it is ensured that the performance of the repaired drill bit is significantly improved, and its service life is extended by more than 30% on average compared with traditional repair methods, providing strong support for mining enterprises to reduce equipment replacement costs and improve production efficiency.

[0026] 2. Integrated Multi-functional Integrated Collaborative Operation System: The present invention successfully constructs a highly integrated multi-functional integrated collaborative operation system, which organically integrates various key functional modules such as heating, vibration, installation, and laser cladding into a compact and efficient equipment system. Through carefully designed standardized interfaces and advanced collaborative control algorithms, the functional modules achieve close cooperation and efficient linkage. During actual operation, from the handling of the drill bit, heating pretreatment, separation of the drill bit tip, installation of the new drill bit tip, laser cladding repair to the final acceptance of the finished product, each link is completed in one go, realizing one-stop and full-process automation processing of the mining blast hole drill bit from detection to repair. This integrated design brings many significant advantages. It not only greatly reduces the floor area of the equipment. Compared with traditional decentralized repair equipment, the floor area can be reduced by about 60%, effectively saving valuable production space at the mining site. It also significantly reduces the connection cost and fault risk between equipment. The modules work together, greatly improving the overall operation efficiency, providing a more convenient, efficient, and reliable drill bit repair solution for mining enterprises, and strongly promoting the upgrade and transformation of mining equipment maintenance technology.

[0027] 3. Intelligent Remote Monitoring and Adaptive Adjustment Control System: The present invention uses a highly integrated control module and advanced intelligent control software to create an intelligent equipment control system. Operators only need to easily issue simple instructions on the equipped tablet software, and the equipment can automatically and accurately complete complex repair processes according to the preset program. The operation is simple and the interface is user-friendly, enabling even first-time contact staff to quickly get started. This system has a powerful equipment status monitoring function. Through a variety of built-in sensors, it can collect the operating parameters of each module of the equipment in real time, such as the temperature of the heating device, the vibration frequency of the vibration device, the pressure of the installation device, and the power of the laser cladding device, etc. Using advanced data analysis algorithms, it can accurately evaluate the operating conditions of the equipment. Once an abnormal situation is detected, the system can quickly respond and automatically take corresponding adjustment measures, such as adjusting the equipment operating parameters, issuing fault warning signals, etc. In addition, the system also innovatively supports the remote monitoring function.

[0028] 4. Efficient Energy Management and Recycling Mechanism: The heating device uses electromagnetic induction heating technology combined with high-efficiency heat insulation materials to greatly improve energy utilization efficiency. During the heating process, the system intelligently regulates the heating power, accurately matching the energy input according to the drill bit material and heating stage to avoid energy waste. At the same time, the equipment is innovatively designed with an energy recovery module. During the cooling and vibration of the drill bit and other links, the excess energy generated is collected and converted, and stored to supply power to other low-power consumption modules of the equipment, such as part of the power consumption requirements of the control module, realizing the recycling of energy and reducing the overall energy consumption, which conforms to the development concept of green environmental protection.

This material combines a variety of rare metals and special alloy components, and has excellent wear resistance, high temperature resistance, and corrosion resistance. Combined with unique laser cladding process parameters, when repairing the drill bit, it can achieve better metallurgical bonding with the drill bit matrix, and the formed cladding layer is more dense and uniform, significantly enhancing the surface performance of the drill bit.

[0042] Referring to Figures 1 to 8 as shown, a mining blasting hole drill bit on-line repair device includes a truck 1, and a carriage 2 is provided at the tail of the truck 1;

[0043] It also includes an intelligent control module, a controller, a high-precision manipulator 3, a heating device 4, a vibration device 5, a mounting device 6, and a repair device 7. The high-precision manipulator 3 is arranged inside the carriage 2 of the truck 1. The heating device 4 is arranged beside the high-precision manipulator 3. The vibration device 5 is arranged beside the heating device 4. The mounting device 6 is arranged beside the vibration device 5. The repair device 7 is arranged beside the mounting device 6;

[0044] The intelligent control module adopts a highly integrated design concept, integrating all the operations of all devices into a set of advanced control software. Operators only need to easily issue work instructions on the equipped tablet software, and the equipment will automatically operate orderly according to the preset program, greatly simplifying the operation process and reducing the requirements for operators' professional skills. The control software has a friendly user interface, is easy to operate and understand, and even staff who are new to it can quickly get started. At the same time, the control software also has powerful functions of equipment status monitoring, fault diagnosis, and data recording. It can monitor the operating status of each module of the equipment in real time, discover and diagnose potential fault problems in time, and automatically record the operating data and maintenance records of the equipment, providing important data support for the maintenance and performance optimization of the equipment. The controller is electrically connected to the intelligent control module, facilitating the controller to receive the instructions issued by the intelligent control module to start the electrical components in each device. This equipment adopts an external power supply method. If there is no external power supply, a larger box truck can be replaced and a power supply device can be added;

[0045] The vibration device 5 includes a rotating drum 8 and an eccentric component. A support frame 9 is arranged inside the carriage 2. The rotating drum 8 is movably arranged on the top of the support frame 9 through two first rotating shafts. The eccentric component is arranged beside the rotating drum 8;

[0046] The mounting device 6 includes a press-fitting head 10, a mounting table 11, a position adjustment component, and an angle adjustment component. An installation cabinet 12 is arranged inside the carriage 2. The position adjustment component is arranged on the inner top of the mounting table 11. The press-fitting head 10 is fixedly arranged on the position adjustment component. The angle adjustment component is arranged on the inner top of the installation cabinet 12. The mounting table 11 is arranged on the angle adjustment component;

[0047] The repair device 7 includes a laser, a cladding head, a high-definition camera 13 and a buzzer sensor 14. Inside the carriage 2, there is a cabinet 15. The high-definition camera 13 is arranged inside the cabinet 15. The buzzer sensor 14 is fixedly arranged on the outer top of the cabinet 15. Both the laser and the cladding head are arranged inside the cabinet 15. The cladding head is located beside the laser. The drill bit with a newly installed drill tip is transferred into the cabinet 15 by the high-precision manipulator 3. First, the high-definition camera 13 inside the device takes high-definition all-round pictures of the drill bit. Using an advanced image recognition and analysis system, it deeply detects whether the drill bit needs laser cladding and the precise state of the current drill bit, accurately identifies tiny defects, worn areas and potential quality problems. If the detection result shows that laser cladding is needed, the laser automatically and flexibly adjusts key parameters such as laser power, spot size and scanning speed according to the detection data, and cooperates with the cladding head to precisely repair the pressed drill bit, forming a cladding layer on the surface of the drill bit that is firmly bonded to the matrix and has excellent performance, significantly improving the wear resistance, corrosion resistance and service life of the drill bit. If laser cladding is not needed, the drill bit directly enters the fetching box 33. When the high-definition camera 13 determines that the damage degree of the drill bit exceeds the laser cladding repair ability, the buzzer sensor 14 immediately emits a loud and clear reminder signal, and at the same time pauses all related work, avoiding ineffective operations, and timely prompting the staff to take other coping strategies. During the laser cladding process, this equipment continuously monitors and feedback-adjusts the cladding quality in real time to ensure that the performance of the repaired drill bit not only returns to the original level, but even exceeds it. It should be noted that in order to cooperate with this equipment, a new type of metal powder composite material has been developed. This material combines multiple rare metals and special alloy components, and has excellent wear resistance, high temperature resistance and corrosion resistance. Cooperating with unique laser cladding process parameters, when repairing the drill bit, it can achieve better metallurgical bonding with the drill bit matrix, and the formed cladding layer is more dense and uniform, significantly enhancing the surface performance of the drill bit.

[0048] Refer to Figures 1 to 8 As shown, on the inner bottom of the carriage 2, there is a running track 16 for the horizontal sliding of the high-precision manipulator 3. When the controller receives the corresponding maintenance operation instruction issued by the intelligent control module, the high-precision manipulator 3 is started through the controller, and thus, relying on its excellent precise control ability and extremely high repeat positioning accuracy, it quickly and accurately grabs the drill bit in the placement box 32.

[0049] Refer to Figures 1 to 8As shown in the figure, the heating device 4 includes an electromagnetic induction heating box, which is arranged inside the carriage 2. The outer shell of the electromagnetic induction heating box is made of high-quality heat insulation materials. After the high-precision manipulator 3 grabs the drill bit, it transports the drill bit to the predetermined station on the heating device 4 along the precisely designed walking slideway at a high efficiency speed, that is, transports it to the electromagnetic induction heating box, and then heats the drill bit through electromagnetic induction heating technology. In this process, the drill bit is transported to the corresponding predetermined station of the heating device 4 at a high efficiency speed. The entire picking, placing and transporting process is extremely rapid and can be efficiently completed within 1 minute, greatly reducing the preparation time before maintenance and winning precious time for the subsequent repair process. The electromagnetic induction heating box adopts advanced electromagnetic induction heating technology and combines a high-precision temperature control system to uniformly heat the drill bit according to the pre-set precise temperature curve. During the heating process, the outer shell made of high-quality heat insulation materials effectively reduces heat dissipation and ensures efficient energy utilization. Within 15 minutes, the drill bit is quickly heated to 600 °C, and the temperature control accuracy is maintained within ±10 °C, making the drill bit reach the ideal softening state and creating suitable conditions for the subsequent operation of removing the drill bit tip.

[0050] Refer to Figures 1 to 8 As shown in the figure, the eccentric component includes a first motor 17, an eccentric wheel and a reduction box 18. The reduction box 18 is fixedly arranged on the top of the support frame 9. The first motor 17 is fixedly arranged on the outer wall of the support frame 9, and its output end is inserted into the inside of the reduction box 18. The eccentric wheel is fixedly arranged on the output end of the first motor 17, and the other end of the eccentric wheel is fixedly connected to the end of one of the rotating shafts. The first motor 17 is electrically connected to the controller. After the drill bit reaches the predetermined heating temperature, the high-precision manipulator 3 transfers it smoothly to the vibration device 5 through the walking track 16, that is, places it inside the rotating drum 8, and starts the first motor 17 through the controller, so that its output end drives the eccentric wheel to rotate through the transmission component inside the reduction box 18. Since the rotating drum 8 is movably connected to the support frame 9 through two first rotating shafts, one end of the eccentric wheel is fixedly connected to one end of one of the first rotating shafts, and the eccentric wheel is also fixedly connected to the output end of the first motor 17, an efficient vibration source is generated, and its vibration frequency can be flexibly adjusted within the range of 50 - 200 Hz according to the materials, specifications of different drill bits and actual maintenance requirements. Under the action of vibration with a specific frequency and intensity, the drill bit tip can be quickly and smoothly separated from the drill bit body.

[0051] Refer to Figures 1 to 8As shown in the figure, the position adjustment assembly includes a first electric slide table 19, a second electric slide table 20 and a third electric slide table 21. Sliders 22 are slidably arranged on the outer walls of the first electric slide table 19, the second electric slide table 20 and the third electric slide table 21. An installation plate is fixedly arranged inside the installation cabinet 12. The first electric slide table 19 is fixedly arranged on the installation plate. The second electric slide table 20 is fixedly arranged on the slider 22 of the first electric slide table 19. The third electric slide table 21 is fixedly arranged on the slider 22 of the second electric slide table 20. A cylinder 23 is fixedly arranged on the outer wall of the slider 22 of the third electric slide table 21. A pressing head 10 is fixedly arranged on its output end. The cylinder 23 is electrically connected to the controller. When the drill tip to be separated cools to the safe temperature range, first, the drill body after the drill tip is separated is vertically placed on the clamping block 28 by the high-precision manipulator 3. Then, the high-precision manipulator 3 inserts a new drill tip into the installation hole of the drill body. Then, through the cooperation of the first electric slide table 19, the second electric slide table 20 and the third electric slide table 21, the pressing head 10 is moved to the end facing the drill tip. Then, the cylinder 23 is started by the controller, and its output end drives the pressing head 10 to descend vertically, and the new drill tip is pressed into the installation hole of the drill body by using the pressing head 10.

[0052] Referring to Figures 1 to 8 As shown in the figure, the angle adjustment assembly includes a second motor 24, a driving wheel 25, a driven wheel 26, a belt 27 and a clamping block 28. The second motor 24 is fixedly arranged inside the installation cabinet 12. The driving wheel 25 is fixedly arranged on its output end. The clamping block 28 is rotatably arranged on the top of the installation plate through a second rotating shaft. The driven wheel 26 is fixedly arranged at one end of the second rotating shaft. The belt 27 is sleeved between the driving wheel 25 and the driven wheel 26. The installation table 11 is arranged on the top of the clamping block 28. By starting the second motor 24 through the controller, since its output end is fixedly connected to the driving wheel 25, the driven wheel 26 is fixedly connected to the second rotating shaft, the clamping block 28 is fixedly connected to the second rotating shaft, the driving wheel 25 and the driven wheel 26 are sleeved through the belt 27, and the installation table 11 is designed on the clamping block 28, the installation table 11 can be driven to rotate, meeting the pressing requirements at different angles and improving the flexibility and practicality of the drill tip pressing.

[0053] Referring to Figures 1 to 8 As shown in the figure, a material cavity 29 is arranged at the top of the support frame 9. A discharge pipe 30 is fixedly arranged at the bottom of the material cavity 29. An arc-shaped blanking port is arranged on the outer wall of the rotary drum 8 in the circumferential direction. An arc-shaped electric baffle is arranged on the arc-shaped blanking port. A collection box 31 is arranged below the discharge pipe 30. When the drill is separated, the electric baffle is started through the controller, so that the arc-shaped blanking port is opened, and the drill falls into the interior of the material cavity 29 from the arc-shaped blanking port, and then falls into the interior of the collection box 31 through the discharge pipe 30 at the bottom of the material cavity 29. To the greatest extent, it ensures that the separation task of the drill tip is efficiently completed without damaging the main structure of the drill body.

[0054] Referring toFigures 1 to 8 As shown in the figure, a high-precision pressure sensor is provided on the outer wall of one end of the press-fitting head 10 close to the mounting table 11. The high-precision pressure sensor is electrically connected to the controller. When the press-fitting head 10 presses a new drill tip into the mounting hole on the drill body, the high-precision pressure sensor firmly installs the new drill tip onto the drill body strictly in accordance with the established installation process and preset pressure parameters. During the installation process, the sensor real-time monitors the press-fitting data. Once the data is abnormal, the device immediately stops operating automatically and issues an alarm, effectively ensuring the installation quality and the safe operation of the equipment, and avoiding huge economic losses caused by damaged drills.

[0055] Refer to Figures 1 to 8 As shown in the figure, a placement box 32 is provided at one end inside the carriage 2. When it is determined at the mining site that a blasting hole drill needs to be repaired, the operator smoothly places the drill to be repaired in the specially designed placement box 32, and then inputs the corresponding repair operation instruction on the terminal device equipped with the intelligent control module.

[0056] Refer to Figures 1 to 8 As shown in the figure, a pick-up box 33 is provided at the other end inside the carriage 2. The drill that has completed all the repair processes is automatically transferred to the pick-up box 33 by the high-precision manipulator 3 along the traveling track 16. The pick-up box 33 is provided with clear markings and reasonable classified storage areas, which facilitate workers to quickly identify and pick up the repaired drills and promptly put them into the mining operation, avoiding delaying the mining operation and putting an efficient and convenient end to the entire repair process.

[0057] The working principle of the present invention: The intelligent control module adopts a highly integrated design concept, integrating all the device operations in all equipment into a set of advanced control software. The operator only needs to easily issue a work instruction on the equipped tablet software, and the equipment will automatically operate in an orderly manner according to the preset program, greatly simplifying the operation process and reducing the requirements for the professional skills of the operator. The control software has a friendly user interface, and the operation is simple and easy to understand. Even a staff member who is new to it can quickly get started. At the same time, the control software also has powerful functions of equipment status monitoring, fault diagnosis, and data recording, which can real-time monitor the operating status of each module of the equipment, promptly discover and diagnose potential fault problems, and automatically record the operating data and repair records of the equipment, providing important data support for the maintenance and performance optimization of the equipment. The controller is electrically connected to the intelligent control module, facilitating the controller to receive the instructions issued by the intelligent control module to start the electrical components in each device;

[0058] When it is determined at the mining site that a blasting hole drill needs to be repaired, the operator smoothly places the drill to be repaired in the specially designed placement box 32, and then inputs the corresponding repair operation instruction on the terminal device equipped with the intelligent control module.

[0059] When the controller receives the corresponding maintenance operation instruction issued by the intelligent control module, it starts the high-precision manipulator 3 through the controller. Thus, relying on its excellent precise control ability and extremely high repeat positioning accuracy, it quickly and accurately grabs the drill bit in the placement box 32.

[0060] After the high-precision manipulator 3 grabs the drill bit, it transports the drill bit to the predetermined position on the heating device 4 along the precisely designed walking slideway at a high efficiency speed, that is, transports it to the electromagnetic induction heating box. Thus, the drill bit is heated through the electromagnetic induction heating technology. This process transports the drill bit to the corresponding predetermined position of the heating device 4 at a high efficiency speed. The entire picking and placing and transportation process is extremely rapid and can be efficiently completed within 1 minute, greatly reducing the pre-maintenance preparation time and winning valuable time for the subsequent repair process. The electromagnetic induction heating box adopts advanced electromagnetic induction heating technology and combines a high-precision temperature control system to uniformly heat the drill bit according to the pre-set precise temperature curve. During the heating process, the shell made of high-quality heat insulation material effectively reduces heat loss, ensuring efficient energy utilization. Within 15 minutes, the drill bit is quickly heated to 600 °C, and the temperature control accuracy is maintained within ±10 °C, making the drill bit reach the ideal softening state and creating suitable conditions for the subsequent operation of removing the drill bit tip.

[0061] When the drill bit reaches the predetermined heating temperature, the high-precision manipulator 3 transfers it smoothly to the vibration device 5 through the walking track 16, that is, places it inside the rotating drum 8, and starts the first motor 17 through the controller. Thus, the output end drives the eccentric wheel to rotate through the transmission components inside the reduction box 18. Since the rotating drum 8 is movably connected to the support frame 9 through two first rotating shafts, one end of the eccentric wheel is fixedly connected to one end of one of the first rotating shafts, and the eccentric wheel is also fixedly connected to the output end of the first motor 17, an efficient vibration source is generated. Its vibration frequency can be flexibly adjusted within the range of 50 - 200 Hz according to the material, specification of different drill bits and the actual maintenance requirements. Under the action of vibration with a specific frequency and intensity, the drill bit tip is quickly and smoothly separated from the drill bit body.

[0062] After the drill bit is separated, the electric baffle is started through the controller, so that the arc-shaped blanking port is opened, because the drill bit falls into the inside of the material cavity 29 from the arc-shaped blanking port, and then falls into the inside of the collection frame 31 through the discharge pipe 30 at the bottom of the material cavity 29. To the greatest extent, it ensures that the separation task of the drill bit tip is efficiently completed without damaging the main structure of the drill bit.

[0063] After the drill bit tip to be separated is cooled to the safe temperature range, first, the high-precision manipulator 3 vertically places the drill bit body after the separation of the drill bit tip on the clamping block 28. Then, the high-precision manipulator 3 inserts a new drill bit tip into the mounting hole of the drill bit body. Then, through the cooperation of the first electric slide table 19, the second electric slide table 20 and the third electric slide table 21, the pressing head 10 is moved to one end facing the drill bit tip. Then, the controller starts the cylinder 23, and its output end drives the pressing head 10 to descend vertically, and the new drill bit tip is pressed into the mounting hole of the drill bit body by using the pressing head 10.

[0064] The controller starts the second motor 24. Since its output end is fixedly connected to the driving wheel 25, the driven wheel 26 is fixedly connected to the second rotating shaft, the clamping block 28 is fixedly connected to the second rotating shaft, the driving wheel 25 and the driven wheel 26 are sleeved by a belt 27, and the mounting table 11 is designed on the clamping block 28, so that the mounting table 11 can be driven to rotate, meeting the pressing requirements at different angles and improving the flexibility and practicality of the drill bit tip pressing.

[0065] When the pressing head 10 presses the new drill bit tip into the mounting hole on the drill bit body, the high-precision pressure sensor firmly installs the new drill bit tip on the drill bit body in strict accordance with the established installation process and preset pressure parameters. During the installation process, the sensor real-time monitors the pressing data. Once the data is abnormal, the device immediately stops operating automatically and issues an alarm, effectively ensuring the installation quality and the operation safety of the equipment, and avoiding huge economic losses caused by damaging the drill bit.

[0066] The drill bit with the new drill bit tip installed is transferred to the inside of the cabinet body 15 by the high-precision manipulator 3. First, the high-definition camera 13 inside the device takes a full-range high-definition photo of the drill bit. By using an advanced image recognition and analysis system, it deeply detects whether the drill bit needs laser cladding and the precise state of the current drill bit, accurately identifies tiny defects, worn areas and potential quality problems. If the detection result shows that laser cladding is required, the laser automatically and flexibly adjusts key parameters such as laser power, spot size and scanning speed according to the detection data, and cooperates with the cladding head to precisely repair the pressed drill bit, forming a cladding layer on the surface of the drill bit that is firmly combined with the matrix and has excellent performance, significantly improving the wear resistance, corrosion resistance and service life of the drill bit. If laser cladding is not required, the drill bit directly enters the storage box 33. When the high-definition camera 13 determines that the damage degree of the drill bit exceeds the laser cladding repair ability, the buzzer sensor 14 immediately emits a loud and clear reminder signal, and at the same time pauses all related work, avoiding ineffective operations, and timely prompting the staff to take other coping strategies. During the laser cladding process, this device continuously monitors and feedback-adjusts the cladding quality in real time to ensure that the performance of the repaired drill bit not only returns to the original level, but even exceeds it.

[0067] The drill bit that has completed all the repair processes is automatically transferred by the high-precision manipulator 3 along the walking track 16 to the storage box 33. The storage box 33 is provided with clear markings and reasonable classified storage areas, which facilitate workers to quickly identify and pick up the repaired drill bits and promptly put them into the mining operation, avoiding delaying the mining operation and drawing an efficient and convenient conclusion to the entire repair process.
