Description

Technical Field

[0001] The utility model relates to the technical field of circuit board manufacturing, in particular to a drilling device capable of self-removing drilling dirt for a carbon film plate. Background Art

[0002] In the electronics industry, multi-layer circuit boards are indispensable components of electronic devices, which carry the electrical connection and signal transmission functions between electronic components. For multi-layer circuit boards designed with thick copper (≥3OZ) inner layers, drilling technology is particularly important, but it also faces a series of technical challenges.

[0003] Thick copper circuit boards have thick copper layers, so it is difficult to remove the drill dirt produced when the drill bit cuts the copper layer in time. These drill dirt mainly include copper chips, resin fragments, and other impurities generated during the drilling process. Since copper has good thermal conductivity, the heat generated during the drilling process should be dissipated by timely removal of the drill dirt, but the thick copper layer causes excessive heat accumulation, which not only affects the drilling efficiency, but may also cause thermal damage to the drill bit and circuit board.

[0004] Because copper materials have certain toughness and ductility, copper wire drawing is prone to occur during the drilling process (copper wire drawing means that when the drill bit penetrates the copper layer, the copper material is stretched into filaments, and these filaments may be entangled on the drill bit or remain in the drill hole), resulting in reduced drilling quality and even causing serious problems such as faults or copper layer dislocation inside the circuit board.

[0005] In addition to the above-mentioned drilling quality problems, drilling contamination will also affect the outer circuit pattern of the circuit board. Especially when drilling holes in thick copper plates, drilling contamination is easy to adhere to the outer circuit and form a tin ring with the tin on the circuit, which not only affects the aesthetics of the circuit, but more importantly, may cause short circuits or open circuits between circuits, thereby affecting the performance of the entire circuit board.

[0006] In addition, thick copper multilayer circuit boards are usually laminated with prepregs containing a high amount of resin during production. However, when prepregs with a resin content of 72% are used for lamination, problems such as insufficient resin filling or voids are likely to occur. These problems not only reduce the mechanical strength of the circuit board, but may also become potential electrical failure points.

[0007] In summary, due to the thick copper layer, it is easy to cause technical problems such as untimely discharge of drilling contamination, heat accumulation, copper wire drawing, contamination of outer circuit patterns, and insufficient filling of resin. The existence of these problems not only affects the production efficiency and quality of the circuit board, but may also have a serious impact on the performance and reliability of the final electronic product.

[0008] Therefore, a self-drilling and anti-smudge drilling device for a carbon film plate is proposed. Utility Model Content

[0009] In view of this, the embodiment of the utility model hopes to provide a drilling device for a carbon film plate that can automatically remove drilling contamination, so as to solve or alleviate the technical problem existing in the prior art, that is, how to automatically discharge drilling contamination from the drill hole during the drilling process, and at least provide a beneficial option for this;

[0010] The technical solution of the embodiment of the utility model is implemented as follows: a drilling device for a carbon film plate that can self-remove drilling dirt, including a drill 5 for drilling driven by a rotating mechanism 4 in the traditional technology, and the improvement of the technical solution is: at least three groups of linear feed modules 2 arranged in an annular manner work together. These modules are docked to the outside of the connecting platform 7, and each module can adjust the angle of the corresponding side of the connecting platform 7. When all the linear feed modules 2 output according to a certain time and feed amount, they can jointly control the connecting platform 7 to perform universal azimuth adjustment, thereby ensuring the accuracy of drilling. A rotating mechanism 4 is installed on the connecting platform 7, which is responsible for driving the drill 5 to rotate for drilling. In addition, an adjusting electric cylinder 3 is also equipped in the middle of the connecting platform 7, and the function of this electric cylinder is to enable the drill 5 to perform precise linear displacement within the drilling tolerance range. The drill 5 is the main tool for drilling, and air holes 501 are specially opened on it. These air holes can spray airflow during the drilling process to play a role in removing drilling dirt.

[0011] During the drilling process, multiple linear feed modules 2 first cooperate with each other to drive the connecting table 7 and the drill bit 5 thereon to the accurate position. Subsequently, the rotating mechanism 4 starts to work, driving the drill bit 5 to rotate and drill. When copper drill dirt is generated during the drilling process, the adjusting electric cylinder 3 will control the drill bit 5 to make appropriate linear displacement within the drilling tolerance range to leave space for jet cleaning. At this time, the air hole 501 on the drill bit 5 will spray air to effectively spray the copper drill dirt out of the drill hole. If the position of the drill dirt does not match the linear movement position of the drill bit 5 controlled by the adjusting electric cylinder 3, the staff will confirm it and further control each linear feed module 2 to make the connecting table 7 perform universal azimuth adjustment to ensure that the linear movement position of the drill bit 5 matches the position of the drill dirt. Subsequently, the air hole 501 sprays air again to spray the drill dirt out of the drill hole. This process will be executed repeatedly until the drill hole is fully formed.

[0012] In one embodiment, the feed module 2 is an important component in the drilling device for accurately controlling the drilling position, and is mainly composed of a rotary actuator 201, a first rocker arm 202, a second rocker arm 203, a first universal joint coupling 204 and other components:

[0013] 1) Rotary actuator 201: It is fixed on the frame 1 and serves as a power source to drive the first rocker arm 202 to rotate. The rotary actuator 201 can set the rotation angle and speed by accurately controlling the system, thereby achieving precise control of the drilling position.

[0014] 2) First rocker arm 202: One end is connected to the rotary actuator 201 and is driven to rotate. The other end is connected to one end of the second rocker arm 203 through the first universal joint coupling 204. The main function of the first rocker arm 202 is to transmit the rotational force of the rotary actuator 201 to the second rocker arm 203.

[0015] 3) Second rocker arm 203: Its characteristic is that one end and the other end are universally hinged to the other end of the first rocker arm 202 and the connecting platform 7 respectively through the first universal joint coupling 204. This design enables the second rocker arm 203 to convert the received rotational force into a feed force and transmit it to the connecting platform 7. In this way, the linear feed module 2 can achieve precise control of the connecting platform 7, and then control the position of the drilling hole.

[0016] 4) The first universal joint coupling 204 is a coupling capable of transmitting torque at multiple angles, which ensures that the second rocker arm 203 can flexibly perform multiple angle conversions when receiving rotational force, thereby achieving the transmission of feed force.

[0017] When all the linear feed modules 2 output according to a certain time and feed amount, they work together on the connecting platform 7 to enable it to be universally adjusted. This adjustment method is very flexible and can adapt to various complex drilling requirements.

[0018] In one implementation manner, the rotary actuator 201 is a servo motor, and the output shaft of the servo motor is fixed in the frame 1 .

[0019] In one embodiment, a rotating mechanism 4 is also included, which is a key component in the drilling device responsible for driving the drill bit 5 to rotate to complete the drilling task:

[0020] 1) Frame 401: It constitutes the basic support structure of the rotating mechanism 4 and provides a stable installation platform for other components. The design of the frame 401 ensures the stability and rigidity of the entire rotating mechanism, so that the rotating torque can be accurately transmitted.

[0021] 2) Executing motor 402: installed on the frame 401, it is the power source for driving the hollow transmission shaft 407 to rotate. The executing motor 402 can drive the hollow transmission shaft 407 at a preset speed and direction through a precise control system, thereby controlling the rotation of the drill bit 5.

[0022] 3) Hollow transmission shaft 407: Rotatingly cooperates with the frame 401 and is driven to rotate by the execution motor 402. A drill bit 5 is fixedly installed at the bottom of the hollow transmission shaft 407, so when the transmission shaft rotates, the drill bit 5 will also rotate accordingly, thereby completing the drilling action.

[0023] 4) Air holes 501 and air passage: The drill bit 5 is provided with air holes 501, which are connected with the inner cavity of the hollow transmission shaft 407, and together form a complete air passage. This air passage is used to spray air during the drilling process to remove copper drilling dirt generated during drilling and keep the drilled hole clean.

[0024] When the rotating mechanism 4 is working, the executive motor 402 drives the hollow transmission shaft 407 to rotate, thereby driving the drill 5 to drill. During the drilling process, the airflow in the airway will be ejected through the air hole 501 to promptly remove the drilling dirt generated in the drilling hole, thereby ensuring the quality and efficiency of the drilling.

[0025] In one embodiment, a rotating mechanism 4 is also included, which is responsible for providing a stable air source for airflow cleaning during the drilling process:

[0026] 1) Airtight flange 405: The airtight flange 405 is installed on the upper end surface of the hollow transmission shaft 407. Its main function is to ensure the airtightness of the airway and provide a stable airflow for the internal airway of the hollow transmission shaft 407. The design of the airtight flange ensures that the gas will not leak from the connection between the hollow transmission shaft 407 and the flange, ensuring the stability and efficiency of the airflow.

[0027] 2) Frame 1 and air pump 101: Frame 1 is the basic structure of the drilling device, and an air pump 101 is arranged inside it. As the power source of the air supply system, the air pump 101 is responsible for generating a stable airflow. The selection and configuration of the air pump need to meet the requirements of the drilling device for clean airflow, ensuring that sufficient airflow can be provided to remove drilling dirt during the drilling process.

[0028] 3) Hose 102: Hose 102 is a flexible pipe connecting the air pump 101 and the airtight flange 405. It is responsible for transmitting the airflow generated by the air pump 101 to the airtight flange 405 and then into the internal air passage of the hollow transmission shaft 407. The hose 102 needs to have good flexibility and airtightness to ensure that the airflow can be transmitted smoothly and without leakage.

[0029] When the drilling device is working, the air pump 101 is started and generates a stable airflow. The airflow is transmitted to the airtight flange 405 through the hose 102, and then enters the internal air passage of the hollow transmission shaft 407 through the airtight flange 405. Finally, the airflow is ejected through the air hole 501 on the drill bit 5 to remove the drilling dirt generated during the drilling process.

[0030] In one embodiment, it is also necessary to optimize how the actuator motor 402 drives the hollow transmission shaft 407 to rotate, especially when the airtight flange 405 blocks the axial direction of the hollow transmission shaft 407:

[0031] 1) Driving bevel gear 403: The driving bevel gear 403 is fixedly connected to the output shaft of the execution motor 402. When the execution motor 402 is started, it drives the driving bevel gear 403 to rotate.

[0032] 2) Driven bevel gear 404: The driven bevel gear 404 is fixed on the upper surface of the hollow transmission shaft 407 and meshes with the driving bevel gear 403. When the driving bevel gear 403 rotates, it drives the driven bevel gear 404 to rotate, thereby driving the hollow transmission shaft 407 to rotate.

[0033] 3) Connection between the airtight flange 405 and the hollow transmission shaft 407: Since the airtight flange 405 is provided on the upper end surface of the hollow transmission shaft 407, this may block the axial direction of the hollow transmission shaft 407, making it difficult to drive directly in the axial direction. Therefore, by using a bevel gear transmission mechanism (i.e., the driving bevel gear 403 and the driven bevel gear 404), the rotational torque of the actuator motor 402 can be effectively transmitted to the hollow transmission shaft 407 without directly operating the axial direction of the hollow transmission shaft 407.

[0034] 4) Center axis hole of driven bevel gear: The center axis hole of driven bevel gear 404 is designed to be adaptable to airtight flange 405, which can ensure the connectivity of the airway without affecting the transmission efficiency of the gear.

[0035] In one embodiment, it is also necessary to solve the problem of the hose 102 being entangled due to the rotation of the driven bevel gear 404, which is achieved by introducing a bearing 406:

[0036] 1) Configuration of bearing 406: The outer and inner bearings of bearing 406 are fixed to hollow transmission shaft 407 and airtight flange 405, respectively. Meanwhile, the inner bearing of bearing 406 is also fixed to frame 401. This configuration allows hollow transmission shaft 407 to rotate freely under the drive of driven bevel gear 404, while airtight flange 405 remains stationary, thereby preventing hose 102 connected to airtight flange 405 from getting entangled.

[0037] 2) Interaction between the driven bevel gear and the bearing: When the driven bevel gear 404 rotates, it will drive the airtight flange 405 to rotate together, but due to the existence of the bearing 406, this rotation force is offset by the roller of the bearing 406. Therefore, the airtight flange 405 does not rotate with the rotation of the driven bevel gear 404 and remains stationary.

[0038] 3) Free rotation of the hollow transmission shaft: Since the bottom of the driven bevel gear 404 is matched with the upper top surface of the hollow transmission shaft 407, and the structural design of the bearing 406 will not interfere with the rotation of the hollow transmission shaft 407, the hollow transmission shaft 407 can be driven to rotate normally by the driven bevel gear 404 without being affected by the bearing 406.

[0039] In one embodiment, the cylinder body and piston rod of the adjusting electric cylinder 3 are respectively and universally hinged to the middle part of the connecting platform 7 through the second universal joint coupling 301. This connection mode allows the adjusting electric cylinder 3 to move flexibly in multiple directions while maintaining a stable connection with the connecting platform 7. When the adjusting electric cylinder 3 is extended or retracted, the second universal joint coupling 301 can adapt to this movement to ensure smooth transmission of torque.

[0040] In one embodiment, a multi-degree-of-freedom robot arm 6 is also included, and the end effector of the multi-degree-of-freedom robot arm 6 is connected to the frame 1. The end effector of the multi-degree-of-freedom robot arm 6 is connected to the frame 1. This connection method ensures the stability of the robot arm and the accuracy of operation. The frame 1 serves as the supporting structure of the entire system and provides a stable operating platform for the robot arm. By connecting the end effector of the multi-degree-of-freedom robot arm 6 to the frame 1, not only the operating accuracy and stability of the robot arm can be improved, but also its working range can be expanded, so that it can adapt to more complex working environments.

[0041] Compared with the prior art, the beneficial effects of the utility model are:

[0042] 1. Self-cleaning mechanism: The utility model realizes the instant removal of drilling dirt by introducing high-pressure airflow during the drilling process. This design significantly improves the efficiency of drilling operations because it is no longer necessary to frequently stop the operation to manually clean the drilling dirt. At the same time, timely removal of drilling dirt during the drilling process can prevent the influence of debris on the drilling accuracy, thereby improving the quality and accuracy of drilling. At the same time, a clean environment also helps to extend the service life of the drill bit. Moreover, the high degree of automation reduces the need for manual intervention, and reduces the difficulty and labor intensity of operation. The operator only needs to monitor the operating status of the equipment without frequent manual cleaning.

[0043] 2. Flexibility and precision: The utility model can realize universal angle adjustment through the cooperation of multiple linear feed modules. This design provides extremely high flexibility and precision, so that the drill bit can be accurately positioned to any required angle and position. This is crucial for handling complex or irregular drilling tasks, because it allows the drill bit to approach the work surface at the best angle, thereby improving the accuracy and quality of drilling.

[0044] 3. Adaptive drilling dirt removal: When the position of the drilling dirt does not match the linear movement position of the drill bit controlled by the adjustment electric cylinder, the staff can promptly confirm and control each linear feed module to make the connection table perform universal azimuth adjustment. This real-time feedback and adjustment mechanism ensures that the linear movement position of the drill bit always matches the position of the drilling dirt, thereby improving the efficiency of drilling dirt removal. This adaptability enables the system to cope with various complex drilling environments and conditions.

[0045] 4. Improve production efficiency: Since the system can adjust the position and angle of the drill bit, it can reduce the situation of repeated drilling or poor drilling quality caused by incomplete drilling pollution removal. This not only improves production efficiency, but also reduces material waste and cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] In order to make the above-mentioned purposes, features and advantages of the utility model more understandable, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed below;

[0054] In the prior art, due to the thick copper layer of the multi-layer circuit board designed with thick inner layer circuit (≥3OZ), it is easy to cause technical problems such as untimely discharge of drilling pollution, heat accumulation, copper wire drawing, contamination of outer layer circuit pattern and insufficient filling of resin. The existence of these problems not only affects the production efficiency and quality of the circuit board, but also may have a serious impact on the performance and reliability of the final electronic product; for this reason, please refer to Figure 1-5 , this specific embodiment will provide a related technical solution to solve the above technical problems: a self-drilling and anti-smudge drilling device for a carbon film plate, comprising a drill 5 for drilling driven by a rotating mechanism 4 in the conventional technology, and the improvement of the technical solution is: it also includes at least three groups of linear feed modules 2 arranged in an annular manner and connected to a circle outside the connecting platform 7; each linear feed module 2 can adjust the angle of the corresponding side of the connecting platform 7; when all the linear feed modules 2 output according to a certain time and feed amount, the connecting platform 7 can be controlled to make a universal azimuth adjustment;

[0055] A rotating mechanism 4 is installed on the connecting platform 7, and an adjusting electric cylinder 3 is provided in the middle of the connecting platform 7 for making the drill bit 5 perform linear displacement within the drilling tolerance range;

[0056] The drill bit 5 is provided with an air hole 501 through which air can be ejected.

[0057] When the above device is drilling, first, multiple linear feed modules 2 cooperate with each other to drive the connection table 7 and the drill bit 5 thereon to be in place, and then the rotating mechanism 4 drives the drill bit 5 to rotate and start drilling; copper drill dirt will be generated during drilling, and at this time, the adjusting electric cylinder 3 controls the drill bit 5 to make appropriate adjustments within the tolerance range of the drilling tolerance, and after leaving a gap, the air hole 501 on the drill bit 5 sprays air to spray the copper drill dirt out of the drill hole; then the adjusting electric cylinder 3 controls the drill bit 5 to reset and continue drilling. If the position where the copper drill dirt appears does not conform to the linear movement position of the drill bit 5 controlled by the adjusting electric cylinder 3, after confirmation by the staff, each linear feed module 2 is further controlled to make the connection table 7 perform universal azimuth adjustment and make the linear movement position of the drill bit 5 controlled by the adjusting electric cylinder 3 further adapt to the position of the drill dirt, and then the air hole 501 sprays air to spray the copper drill dirt out of the drill hole; the above steps will be repeated for multiple rounds until the drill hole is completely formed.

[0058] In the above scheme: at least three groups of linear feed modules 2 arranged in a ring work together. These modules are docked to the outside of the connecting platform 7, and each module can adjust the angle of the corresponding side of the connecting platform 7. When all the linear feed modules 2 output according to a certain time and feed amount, they can jointly control the connecting platform 7 to perform universal azimuth adjustment, thereby ensuring the accuracy of drilling. A rotating mechanism 4 is installed on the connecting platform 7, which is responsible for driving the drill bit 5 to rotate for drilling. In addition, an adjusting electric cylinder 3 is also equipped in the middle of the connecting platform 7. The function of this electric cylinder is to enable the drill bit 5 to perform precise linear displacement within the drilling tolerance range. The drill bit 5 is the main tool for drilling, and air holes 501 are specially opened on it. These air holes can spray airflow during the drilling process to play a role in removing drilling dirt.

[0059] In this solution, all electrical components of the device as a whole rely on AC power for energy supply; specifically, the electrical components of the device as a whole are conventionally electrically connected to the AC power output port through devices such as relays, transformers and button panels to meet the energy supply requirements of all electrical components of the device.

[0060] Specifically, a controller is also provided on the outside of the device, which is used to connect and control all electrical components of the device as a whole to be driven according to a pre-set program as a preset value and a driving mode; it should be pointed out that the above-mentioned driving mode corresponds to the corresponding start and stop time intervals, speed, power and other output parameters between the relevant electrical components mentioned below, that is, it meets the requirements of the relevant electrical components described below to drive the relevant mechanical devices to operate according to the functions described therein.

[0061] Preferably, the controller is a PLC controller, which completes the above control requirements through conventional PLC control modes such as ladder diagrams, sequential function diagrams, function block diagrams, instruction tables or structured texts; it should be pointed out that the output parameters such as the start and stop time intervals, speed, power, etc. of the electrical components or other power components driven by its programming are non-limiting; specifically, the relevant drive control is adjusted according to actual usage requirements.

[0062] Specifically, during the drilling process, multiple linear feed modules 2 first cooperate with each other to drive the connecting table 7 and the drill bit 5 thereon to the accurate position. Subsequently, the rotating mechanism 4 starts to work, driving the drill bit 5 to rotate and drill. When copper drill dirt is generated during the drilling process, the adjusting electric cylinder 3 will control the drill bit 5 to perform appropriate linear displacement within the drilling tolerance range to leave space for jet cleaning. At this time, the air hole 501 on the drill bit 5 will spray airflow to effectively spray the copper drill dirt out of the borehole. If the position of the drill dirt does not match the linear movement position of the drill bit 5 controlled by the adjusting electric cylinder 3, the staff will confirm it and further control each linear feed module 2 to make the connecting table 7 perform universal azimuth adjustment to ensure that the linear movement position of the drill bit 5 matches the position of the drill dirt. Subsequently, the air hole 501 sprays airflow again to spray the drill dirt out of the borehole. This process will be executed cyclically until the borehole is fully formed.

[0063] Specifically: Through the synergistic effect of the linear feed module 2, the connecting platform 7, the adjusting electric cylinder 3 and the rotating mechanism 4, the drill 5 is precisely controlled. This control not only ensures the accuracy and efficiency of drilling, but also provides the necessary conditions for subsequent airflow cleaning. The air hole 501 on the drill 5 is used to spray airflow to remove the copper drilling dirt generated during the drilling process. This cleaning method is both efficient and environmentally friendly, and can significantly improve the quality and efficiency of drilling.

[0064] It can be understood that in the above scheme: the drilling device of the present technical solution realizes the automation and flexibility of the drilling process through an automated control system. The coordinated work of multiple linear feed modules 2 and the universal azimuth adjustment function of the connecting table 7 enable the device to adapt to various complex drilling requirements. The method of removing drilling dirt by spraying air through the air hole 501 on the drill nozzle 5 not only improves the cleanliness of the drilled hole, but also avoids the secondary pollution problem that may be caused by traditional cleaning methods. This cleaning method is both efficient and environmentally friendly, and is in line with the development trend of modern manufacturing industry. Through the combination of automated control and efficient cleaning, the drilling device of the present technical solution significantly improves the production efficiency and quality of carbon film plate drilling. This can not only meet the needs of large-scale production, but also bring greater economic benefits and market competitiveness to enterprises.

[0065] In some specific embodiments of this application, please refer to Figure 2 : The linear feed module 2 includes a rotary actuator 201 fixed on the frame 1, and the rotary actuator 201 drives one end of the first rocker arm 202 to rotate. One end and the other end of the second rocker arm 203 are respectively universally hinged to the other end of the first rocker arm 202 and the connecting platform 7 through a first universal joint coupling 204.

[0066] When the rotary actuator 201 is driven, the first rocker arm 202 is controlled to rotate. When the first rocker arm 202 transmits the rotational force to the second rocker arm 203, one end and the other end of the second rocker arm 203 are respectively universally hinged to the other end of the first rocker arm 202 and the connecting platform 7 through the first universal joint coupling 204, so the second rocker arm 203 will convert the rotational force into a feed force and transmit it to the connecting platform 7; furthermore, when all the linear feed modules 2 output according to a certain time and feed amount, the connecting platform 7 can be controlled to perform universal azimuth adjustment.

[0067] In the above scheme: the linear feed module 2 is an important component in the drilling device for accurately controlling the drilling position, and it mainly consists of a rotary actuator 201, a first rocker arm 202, a second rocker arm 203 and a first universal joint coupling 204. The functions of the components are:

[0068] 1) Rotary actuator 201: It is fixed on the frame 1 and serves as a power source to drive the first rocker arm 202 to rotate. The rotary actuator 201 can set the rotation angle and speed by accurately controlling the system, thereby achieving precise control of the drilling position.

[0069] 2) First rocker arm 202: One end is connected to the rotary actuator 201 and is driven to rotate. The other end is connected to one end of the second rocker arm 203 through the first universal joint coupling 204. The main function of the first rocker arm 202 is to transmit the rotational force of the rotary actuator 201 to the second rocker arm 203.

[0070] 3) Second rocker arm 203: Its characteristic is that one end and the other end are universally hinged to the other end of the first rocker arm 202 and the connecting platform 7 respectively through the first universal joint coupling 204. This design enables the second rocker arm 203 to convert the received rotational force into a feed force and transmit it to the connecting platform 7. In this way, the linear feed module 2 can achieve precise control of the connecting platform 7, and then control the position of the drilling hole.

[0071] 4) The first universal joint coupling 204 is a coupling capable of transmitting torque at multiple angles, which ensures that the second rocker arm 203 can flexibly perform multiple angle conversions when receiving rotational force, thereby achieving the transmission of feed force.

[0072] When all the linear feed modules 2 output according to a certain time and feed amount, they work together on the connecting platform 7 to enable it to be universally adjusted. This adjustment method is very flexible and can adapt to various complex drilling requirements.

[0073] Specifically: The working principle of the linear feed module 2 is mainly to use the rotary actuator 201 to drive the first rocker arm 202 to rotate, and then transmit the rotational force to the second rocker arm 203 through the first universal joint coupling 204, and the second rocker arm 203 converts the rotational force into a feed force to act on the connecting platform 7. In this way, precise control of the drilling position is achieved. The coordinated work of multiple linear feed modules 2 enables the connecting platform 7 to perform universal azimuth adjustment to meet various drilling requirements.

[0074] It can be understood that in the above scheme: the linear feed module 2 realizes precise control of the drilling position through the coordinated action of the rotary actuator 201, the first rocker arm 202, the second rocker arm 203 and the first universal joint coupling 204. This module is not only compact and flexible, but also can realize efficient feeding action, thereby improving the accuracy and efficiency of drilling. In addition, the coordinated work of multiple linear feed modules 2 also enables the drilling device to adapt to various complex drilling requirements, further improving its practicality and flexibility.

[0075] It can be understood that in the above scheme: the coordination mode of the frame 1, the linear feed module 2 and the connecting platform 7 is essentially equivalent to a parallel mechanism; for those skilled in the art, a conventional parallel mechanism can be used to store a preset program using a PID controller algorithm, that is, to realize the universal angle adjustment function according to the corresponding time step.

[0076] Furthermore, the rotary actuator 201 is a servo motor, and the output shaft of the servo motor is fixed in the frame 1 .

[0077] In some specific embodiments of this application, please refer to Figures 3-5 The rotating mechanism 4 includes a frame 401 and an executive motor 402 mounted thereon. A hollow transmission shaft 407 is rotatably mounted on the frame 401. The hollow transmission shaft 407 is driven to rotate by the executive motor 402. A drill bit 5 is fixedly arranged at the bottom of the hollow transmission shaft 407. The interior of the hollow transmission shaft 407 and the air hole 501 form a complete airway.

[0078] In the above scheme: the rotating mechanism 4 is a key component in the drilling device responsible for driving the drill bit 5 to rotate to complete the drilling task, and its functions are:

[0079] 1) Frame 401: It constitutes the basic support structure of the rotating mechanism 4 and provides a stable installation platform for other components. The design of the frame 401 ensures the stability and rigidity of the entire rotating mechanism, so that the rotating torque can be accurately transmitted.

[0080] 2) Executing motor 402: installed on the frame 401, it is the power source for driving the hollow transmission shaft 407 to rotate. The executing motor 402 can drive the hollow transmission shaft 407 at a preset speed and direction through a precise control system, thereby controlling the rotation of the drill bit 5.

[0081] 3) Hollow transmission shaft 407: Rotatingly cooperates with the frame 401 and is driven to rotate by the execution motor 402. A drill bit 5 is fixedly installed at the bottom of the hollow transmission shaft 407, so when the transmission shaft rotates, the drill bit 5 will also rotate accordingly, thereby completing the drilling action.

[0082] 4) Air holes 501 and air passage: The drill bit 5 is provided with air holes 501, which are connected with the inner cavity of the hollow transmission shaft 407, and together form a complete air passage. This air passage is used to spray air during the drilling process to remove copper drilling dirt generated during drilling and keep the drilled hole clean.

[0083] When the rotating mechanism 4 is working, the executive motor 402 drives the hollow transmission shaft 407 to rotate, thereby driving the drill 5 to drill. During the drilling process, the airflow in the airway will be ejected through the air hole 501 to promptly remove the drilling dirt generated in the drilling hole, thereby ensuring the quality and efficiency of the drilling.

[0084] Specifically, the working principle of the rotating mechanism 4 is mainly to use the executive motor 402 to drive the hollow transmission shaft 407 to rotate, thereby driving the drill bit 5 to complete the drilling action. At the same time, through the design of the air hole 501 and the air channel, the function of removing drilling dirt during the drilling process is realized. This design not only improves the accuracy and efficiency of drilling, but also ensures the cleanliness of the drilling.

[0085] It can be understood that in the above scheme: the rotating mechanism 4 is one of the core components of the drilling device, which is responsible for driving the drill bit 5 to perform accurate and efficient drilling. By accurately controlling the motor 402 and stably transmitting the hollow transmission shaft 407, accurate control of the drilling depth and the aperture is achieved. At the same time, the design of the air hole 501 and the airway enables timely removal of drilling dirt during the drilling process, ensuring the quality and cleanliness of the drilling. The design of this rotating mechanism not only improves the working efficiency of the drilling device, but also extends the service life of the drill bit.

[0086] Since the air hole 501 needs to spray airflow, in some specific embodiments of the present application, please refer to Figures 3-5 : The airtight flange 405 is arranged on the upper end surface of the hollow transmission shaft 407, which is responsible for supplying air to the internal air passage of the hollow transmission shaft 407. An air pump 101 and a hose 102 connected thereto are arranged in the frame 1, and the hose 102 is connected to the inner side wall of the hollow transmission shaft 407 through the airtight flange 405.

[0087] In the above scheme: the rotating mechanism 4 is also responsible for providing a stable air source for the airflow cleaning during the drilling process, and its principle is:

[0088] 1) Airtight flange 405: The airtight flange 405 is installed on the upper end surface of the hollow transmission shaft 407. Its main function is to ensure the airtightness of the airway and provide a stable airflow for the internal airway of the hollow transmission shaft 407. The design of the airtight flange ensures that the gas will not leak from the connection between the hollow transmission shaft 407 and the flange, ensuring the stability and efficiency of the airflow.

[0089] 2) Frame 1 and air pump 101: Frame 1 is the basic structure of the drilling device, and an air pump 101 is arranged inside it. As the power source of the air supply system, the air pump 101 is responsible for generating a stable airflow. The selection and configuration of the air pump need to meet the requirements of the drilling device for clean airflow, ensuring that sufficient airflow can be provided to remove drilling dirt during the drilling process.

[0090] 3) Hose 102: Hose 102 is a flexible pipe connecting the air pump 101 and the airtight flange 405. It is responsible for transmitting the airflow generated by the air pump 101 to the airtight flange 405 and then into the internal air passage of the hollow transmission shaft 407. The hose 102 needs to have good flexibility and airtightness to ensure that the airflow can be transmitted smoothly and without leakage.

[0091] When the drilling device is working, the air pump 101 is started and generates a stable airflow. The airflow is transmitted to the airtight flange 405 through the hose 102, and then enters the internal air passage of the hollow transmission shaft 407 through the airtight flange 405. Finally, the airflow is ejected through the air hole 501 on the drill bit 5 to remove the drilling dirt generated during the drilling process.

[0092] Specifically, the working principle of the air supply system is to generate a stable airflow by using the air pump 101, transmit the airflow to the internal air passage of the hollow transmission shaft 407 through the hose 102 and the airtight flange 405, and finally eject it through the air hole 501 on the drill bit 5 to remove the drilling dirt. In the whole process, the airtight flange 405 ensures the airtightness of the air passage, prevents gas leakage, and ensures the stability and efficiency of the airflow.

[0093] It can be understood that in the above scheme: the air supply system is an indispensable part of the drilling device, which provides a stable air source for the airflow cleaning during the drilling process. Through the coordinated work of the air pump 101, the hose 102 and the airtight flange 405, it is ensured that the airflow can be smoothly and leak-freely transmitted to the air hole 501 of the drill bit 5, thereby effectively removing the drilling dirt generated during the drilling process. This design not only improves the quality and efficiency of drilling, but also extends the service life of the drill bit. At the same time, the stability and reliability of the air supply system also provide a guarantee for the long-term continuous operation of the drilling device.

[0094] Furthermore, the air inlet of the air pump 101 needs to be connected to a compressed gas cylinder storing gas, and the gas cylinder is fixed in the frame 1.

[0095] Since the execution motor 402 needs to drive the hollow transmission shaft 407 to rotate, and the axial direction of the hollow transmission shaft 407 is blocked by the airtight flange 405; therefore, in some specific embodiments of the present application, please refer to Figures 3-5 Therefore, the output shaft of the actuator motor 402 is fixed with the driving bevel gear 403, the upper top surface of the hollow transmission shaft 407 is fixed to the bottom of the driven bevel gear 404, and the driving bevel gear 403 is meshed with the driven bevel gear 404. At the same time, the central axis hole of the driven bevel gear 404 can be adapted to the airtight flange 405 to dock with the hollow transmission shaft 407.

[0096] In the above scheme: the implementation points of the corresponding functions are:

[0097] 1) Driving bevel gear 403: The driving bevel gear 403 is fixedly connected to the output shaft of the execution motor 402. When the execution motor 402 is started, it drives the driving bevel gear 403 to rotate.

[0098] 2) Driven bevel gear 404: The driven bevel gear 404 is fixed on the upper surface of the hollow transmission shaft 407 and meshes with the driving bevel gear 403. When the driving bevel gear 403 rotates, it drives the driven bevel gear 404 to rotate, thereby driving the hollow transmission shaft 407 to rotate.

[0099] 3) Connection between the airtight flange 405 and the hollow transmission shaft 407: Since the airtight flange 405 is provided on the upper end surface of the hollow transmission shaft 407, this may block the axial direction of the hollow transmission shaft 407, making it difficult to drive directly in the axial direction. Therefore, by using a bevel gear transmission mechanism (i.e., the driving bevel gear 403 and the driven bevel gear 404), the rotational torque of the actuator motor 402 can be effectively transmitted to the hollow transmission shaft 407 without directly operating the axial direction of the hollow transmission shaft 407.

[0100] 4) Center axis hole of driven bevel gear: The center axis hole of driven bevel gear 404 is designed to be adaptable to airtight flange 405, which can ensure the connectivity of the airway without affecting the transmission efficiency of the gear.

[0101] Specifically, by using a bevel gear transmission mechanism, the actuator motor 402 can effectively drive the hollow transmission shaft 407 blocked by the airtight flange 405. The rotation of the active bevel gear 403 drives the driven bevel gear 404 to rotate, thereby driving the hollow transmission shaft 407 to rotate. This design cleverly solves the driving problem caused by the blocking of the airtight flange 405.

[0102] It can be understood that in the above scheme: the bevel gear transmission mechanism in this embodiment provides a flexible and efficient driving force transmission method for the drilling device. Even when the airtight flange 405 blocks the axial direction of the hollow transmission shaft 407, it can ensure that the power of the actuator motor 402 can be smoothly and accurately transmitted to the hollow transmission shaft 407, thereby driving the drill bit to perform the drilling operation. This design not only improves the working efficiency and stability of the drilling device, but also enhances its ability to adapt to complex working environments.

[0103] Due to the introduction of the driven bevel gear 404, when the driven bevel gear 404 drives the hollow transmission shaft 407 to rotate, it will further drive the airtight flange 405 to rotate, thereby causing the hose 102 to be entangled; therefore, in some specific embodiments of the present application, please refer to Figure 4 : Therefore, the outer and inner bearings of a bearing 406 are fixed to the hollow transmission shaft 407 and the airtight flange 405, respectively, and the inner bearing of the bearing 406 is fixed to the frame 401. When the driven bevel gear 404 rotates, the outer bearing of the bearing 406 adapts to its rotation, and the inner bearing of the bearing 406 is fixed to the frame 401 and the airtight flange 405, so the rotation force of the airtight flange 405 that the driven bevel gear 404 should drive is offset by the roller of the bearing 406. At the same time, because the bottom of the driven bevel gear 404 is matched with the upper top surface of the hollow transmission shaft 407, the hollow transmission shaft 407 is not interfered by the mechanism of the bearing 406, and can be driven to rotate normally by the driven bevel gear 404.

[0104] In the above solution, the problem of the hose 102 being entangled due to the rotation of the driven bevel gear 404 is solved by introducing the bearing 406. The principle is as follows:

[0105] 1) Configuration of bearing 406: The outer and inner bearings of bearing 406 are fixed to hollow transmission shaft 407 and airtight flange 405, respectively. Meanwhile, the inner bearing of bearing 406 is also fixed to frame 401. This configuration allows hollow transmission shaft 407 to rotate freely under the drive of driven bevel gear 404, while airtight flange 405 remains stationary, thereby preventing hose 102 connected to airtight flange 405 from getting entangled.

[0106] 2) Interaction between the driven bevel gear and the bearing: When the driven bevel gear 404 rotates, it will drive the airtight flange 405 to rotate together, but due to the existence of the bearing 406, this rotation force is offset by the roller of the bearing 406. Therefore, the airtight flange 405 does not rotate with the rotation of the driven bevel gear 404 and remains stationary.

[0107] 3) Free rotation of the hollow transmission shaft: Since the bottom of the driven bevel gear 404 is matched with the upper top surface of the hollow transmission shaft 407, and the structural design of the bearing 406 will not interfere with the rotation of the hollow transmission shaft 407, the hollow transmission shaft 407 can be driven to rotate normally by the driven bevel gear 404 without being affected by the bearing 406.

[0108] Specifically, by introducing the bearing 406 and fixing its inner and outer bushes on the hollow transmission shaft 407 and the airtight flange 405 (and the frame 401), the goal of allowing the hollow transmission shaft 407 to rotate freely while the airtight flange 405 remains stationary when the driven bevel gear 404 rotates is achieved. In this way, the hose 102 connected to the airtight flange 405 will not be entangled due to the rotation of the driven bevel gear 404.

[0109] It is understandable that in the above solution: the problem of hose 102 being entangled due to the rotation of driven bevel gear 404 is solved by bearing 406. This design not only ensures the normal operation of the drilling device, but also improves its convenience and reliability.

[0110] In some specific embodiments of this application, please refer to Figure 2 The cylinder body and piston rod of the adjusting electric cylinder 3 are respectively and universally hinged to the middle part of the connecting platform 7 through the second universal joint coupling 301. This connection mode allows the adjusting electric cylinder 3 to move flexibly in multiple directions while maintaining a stable connection with the connecting platform 7. When the adjusting electric cylinder 3 is extended or retracted, the second universal joint coupling 301 can adapt to this movement to ensure smooth transmission of torque.

[0111] When the linear feed module 2 is in place, when the adjusting electric cylinder 3 performs the feed adjustment of the above solution, the first universal joint coupling 204 offsets the constraint of the second rocker arm 203, so that the connecting platform 7 can make corresponding position adjustment.

[0112] In some specific embodiments of this application, please refer to Figure 5 : It also includes a multi-degree-of-freedom robotic arm 6, and the end effector of the multi-degree-of-freedom robotic arm 6 is connected to the frame 1. The end effector of the multi-degree-of-freedom robotic arm 6 is connected to the frame 1. This connection method ensures the stability of the robotic arm and the accuracy of operation. The frame 1 serves as the supporting structure of the entire system and provides a stable operating platform for the robotic arm. By connecting the end effector of the multi-degree-of-freedom robotic arm 6 to the frame 1, not only the operating accuracy and stability of the robotic arm can be improved, but also its working range can be expanded, so that it can adapt to more complex working environments. As for the specific adjustment and control method of the multi-degree-of-freedom robotic arm 6, conventional robotic arm control algorithms can be selected, which will not be elaborated here.

[0113] In summary, in view of the related problems in the conventional technology, this specific embodiment is based on the above-mentioned self-drilling and anti-contamination drilling device for carbon film plates, and adopts the following technical means or features to achieve the solution:

[0114] The hollow transmission shaft 407 is designed to be able to transmit rotational torque and has an air passage inside. The airtight flange 405 is installed on the upper end surface of the hollow transmission shaft 407 to ensure the airtightness of the air passage and provide a stable airflow for the internal air passage of the hollow transmission shaft. This design allows gas to pass through the inside of the hollow transmission shaft, and then guide the airflow to the drilling position during the drilling process. An air pump 101 and a hose 102 connected thereto are provided inside the frame 1. The air pump 101 generates a stable airflow, which is transported to the airtight flange through the hose, and then the airflow enters the inner wall of the hollow transmission shaft and is finally discharged through the air holes on the drill bit 5. In this process, the continuous and stable airflow can blow the drilling dirt out of the drilling position during drilling, thereby realizing the automatic discharge of drilling dirt. When the drill bit 5 rotates to drill, it releases a high-pressure airflow through the air holes on it. This airflow can not only help cool the drill bit 5, but also effectively blow away the debris and dust generated during the drilling process to keep the drilling area clean. The operating steps are:

[0115] S1. Generate airflow: First, the air pump 101 generates high-pressure airflow, which is the power source for discharging drilling waste.

[0116] S2. Air flow transmission: Next, the high-pressure air flow is transmitted to the airtight flange 405 through the hose 102, and then enters the internal air passage of the hollow transmission shaft 407 through the airtight flange, thereby ensuring the continuity and stability of the air flow.

[0117] S3. Air discharge and cleaning: Finally, when the drill bit 5 performs drilling operation, the air flow is forcefully discharged through the air hole 501 on the drill bit 5, and the drilling dirt generated during the drilling process is immediately blown away, thereby realizing the automatic discharge of the drilling dirt.

[0118] The above-mentioned embodiments only express the implementation methods of the relevant practical applications of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
