[0077] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0079] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0080] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0081] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0082] Firstly, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown. An embodiment of this application provides a detection device 1 for use in circuit board processing equipment. The circuit board processing equipment includes a spindle 3 and a tool 2, with the tool 2 mounted on the spindle 3. The tool 2 is used to process circuit boards. The detection device 1 includes a mounting base 11 and an image acquisition unit 12. The mounting base 11 has a through hole 111, which extends through the mounting base 11 in a first direction. The spindle 3 can drive the tool 2 to extend into the through hole 111 in the first direction. See reference... Figure 5 As shown, the image acquisition device 12 is used to acquire the outline of the tool 2.

[0083] It should be noted that tool 2 in this application can be a cutting tool. Of course, tool 2 in this application can also be other processing tools. Here, the specific type of tool 2 is not limited. For example, this application uses a cutting tool to refer to tool 2. The spindle 3 is used to drive tool 2 to move, thereby realizing the processing of the circuit board through tool 2. Detecting the diameter of tool 2 can ensure that the diameter of tool 2 is accurately matched with the hole or groove to be processed on the circuit board, avoiding processing errors caused by dimensional deviations. Detecting the length of tool 2 can ensure accurate processing depth. Detecting the wear of tool 2 can monitor the wear degree of tool 2 in a timely manner, avoiding the problem of poor processing quality caused by excessive wear of tool 2 leading to reduced cutting performance. Detecting the spindle runout value of spindle 3 can ensure the stability of tool 2 in the processing process, avoiding the problem of poor processing accuracy caused by excessive spindle runout. Based on the above description, by detecting tool 2 and spindle 3, problems with tool 2 can be detected in time and tool 2 can be replaced in time, avoiding scrap and delays caused by failures or processing errors caused by tool 2 problems during the processing.

[0084] It should be further noted that the length of tool 2 is the length from the tip or the very front of the cutting edge to the end of the shank. The diameter of tool 2 is the diameter of the largest circular trajectory formed by the cutting edge when rotating. Of course, the length and diameter of tool 2 can be defined and modified according to actual production processes. This application defines the length and diameter only in the above exemplary manner.

[0085] It should be further explained that the first direction is Figure 1 The X direction in the equation.

[0086] Specifically, the mounting base 11 serves as a fixing structure for the detection device 1, supporting and fixing structures such as the image acquisition unit 12 within the detection device 1, thereby ensuring the normal operation and functioning of the detection device 1. Since the mounting base 11 has a through hole 111, the contour of the tool 2 is acquired through the image acquisition unit 12, enabling the detection of the tool face wear and spindle runout value. This integrates the detection functions of tool face wear and spindle runout value into a single structure, thereby improving the detection efficiency of the tool 2 and spindle 3.

[0087] It should be noted that the mounting base 11 can be a one-piece molded structure. Similarly, the mounting base 11 can also include multiple structures such as a first fixing member and a second fixing member, and these multiple structures are connected by a detachable connection to form the mounting base 11. Both the first fixing member and the second fixing member can be structures such as fixing plates, fixing blocks, and fixing frames.

[0088] When the mounting base 11 is detachably connected to multiple structures such as the first fixing member and the second fixing member, the first fixing member has a first sub-through hole, the second fixing member has a second sub-through hole, and the first sub-through hole and the second sub-through hole are connected to form the aforementioned through hole 111. The specific structure of the mounting base 11 will not be limited or described in detail here.

[0089] It should be noted that since the tool 2 is connected to the spindle 3, the contour of the tool 2 can be obtained through the image acquisition device 12. The obtained contour of the tool 2 can indirectly reflect the degree of spindle 3 deflection, thereby indirectly realizing the detection of the spindle deflection value.

[0090] In addition, since this application integrates the detection function of tool wear and the detection function of spindle runout into one structure, the overall structure of the detection device 1 is compact and does not occupy the processing space of the circuit board processing equipment. This can reduce the total cost of tool 2 and spindle 3 detection and improve the cost-effectiveness of the detection device 1.

[0091] Furthermore, since the detection device 1 of this application can detect the wear of the tool 2's cutting surface and the spindle runout of the spindle 3, the occurrence of tool breakage can be reduced, and the number of holes drilled by the tool 2 can be flexibly adjusted according to the wear of the tool 2's cutting surface, thereby improving the service life of the tool 2.

[0092] For example, the process of the detection device 1 detecting the wear of the cutting surface of the tool 2 is as follows: the image acquisition unit 12 captures an image of the cutting surface of the tool 2, and performs image processing such as noise reduction and grayscale processing on the captured cutting surface image to improve the quality of the cutting surface image. Specifically, the image processing extracts the cutting surface features of the tool 2, including the wear area and surface cracks, and by comparing it with a standard cutting surface, detects whether there are defects on the cutting surface, thereby determining the degree of wear of the tool 2's cutting surface.

[0093] Optionally, the degree of tool wear is usually measured by the area worn away or the width of the worn surface. The width of the worn surface refers to the distance between the main cutting edge and the worn surface. In this embodiment, the worn area is used as the measurement standard, and a wear ratio, i.e., the tool wear amount, is introduced to characterize the degree of tool wear. The tool wear amount is the ratio of the area worn away to the area before wear. The image acquisition device 12 automatically measures the worn area of ​​the tool 2 and calculates the tool wear amount, thereby monitoring the wear state of the tool in real time.

[0094] For example, the process of detecting the spindle runout value of the spindle 3 by the detection device 1 is as follows: the image acquisition unit 12 captures images of the tool 2 when the spindle 3 is in a static state and a rotating state, and transmits them to the image processing unit of the image acquisition unit 12. The image processing unit uses an algorithm to extract key features of the tool 2 image, such as performing contour and edge recognition on the tool 2 image, and calculates the spindle runout value of the spindle 3 by comparing the contour size of the tool 2 in the static and rotating states. The spindle runout value can be calculated by using a specific algorithm to transform parameters such as the contour area ratio of the tool 2 in the static and rotating states into the corresponding spindle runout value. Of course, the spindle runout value can also be calculated by other methods; here, the method of obtaining the spindle runout value is not limited.

[0095] Understandably, see Figure 3 and Figure 4 As shown, due to the complexity of the cutting surface of the tool, directly detecting the image of the cutting surface increases the difficulty of photoelectric signal conversion in the detection device 1, thereby increasing the computational complexity and hardware and software costs. Furthermore, the poor linearity of the tool can lead to significant deviations in the measured spindle runout value, failing to reflect the true degree of spindle runout. Therefore, this embodiment uses a standard runout bar 21 instead of the cutting tool. The image acquisition device 12 captures images of the standard runout bar 21 when the spindle 3 is stationary and rotating, thereby improving the detection accuracy of the spindle runout value. It is understood that both the standard runout bar 21 and the cutting tool are one type of tool 2 in this application.

[0096] Of course, this application can also directly capture images of the spindle 3 in both stationary and rotating states using the image acquisition device 12, thereby detecting the spindle runout value of the spindle 3. The method for obtaining the spindle runout value will not be elaborated upon here.

[0097] In some embodiments, tool 2 includes a cutting tool; image acquisition device 12 is disposed on the side of mounting base 11 facing the direction of gravity, image acquisition device 12 includes lens 121, at least a portion of lens 121 is disposed within through hole 111; lens 121 faces the cutting tool and is used to acquire the contour of the cutting tool. Wherein, the center line of lens 121 is parallel to the axis of through hole 111.

[0098] Thus, the image acquisition unit 12 is positioned on the side of the mounting base 11 facing the direction of gravity, meaning the lens 121 is located below the direction of gravity relative to the tool. This allows the lens 121 to acquire the tool's outline from bottom to top. On one hand, since the tool's cutting surface faces the direction of gravity, the tool's state during inspection is the same as its state during circuit board processing, eliminating the need for tool posture adjustment. This facilitates the lens 121's acquisition of the tool's cutting surface image. Furthermore, the mounting base 11 can serve as the boundary between the tool's processing space and the image acquisition unit 12's inspection space. By positioning the image acquisition unit 12, the tool, and the spindle 3 on opposite sides of the mounting base 11, the movement of the tool and spindle 3 and the inspection process of the image acquisition unit 12 remain independent, improving the accuracy of the image acquisition unit 12's inspection process. On the other hand, it allows for easier spatial arrangement of the inspection device 1, the tool, and the spindle 3 by the operator, improving space utilization during tool and spindle inspection and facilitating operator operation.

[0099] Furthermore, since the lens 121 is oriented towards the tool, the contour of the tool can be obtained through the lens 121, thereby enabling the detection of tool wear and spindle runout. In this way, the tool wear detection function and the spindle runout detection function can be integrated into one structure, allowing for simultaneous detection of tool wear and spindle runout, which can improve the detection efficiency of the tool and spindle and increase the uptime of the circuit board processing equipment.

[0100] In addition, since the center line of the lens 121 is parallel to the axis of the through hole 111, the lens 121 can accurately capture the profile of the tool, thereby improving the tool face detection accuracy and the spindle runout detection accuracy of the spindle 3.

[0101] In some embodiments, the mounting base 11 has a groove 112 on the side facing the tool 2, and the opening of the through hole 111 on the side facing the tool 2 is located on the bottom wall of the groove 112.

[0102] Thus, since the mounting base 11 has a groove 112 on the side facing the tool 2 and the through hole 111 is located on the bottom wall of the groove 112, the tool 2 can be moved into the groove 112 for testing during the testing process.

[0103] It should be noted again that, as explained above, the mounting base 11 can be a one-piece molded structure. Similarly, the mounting base 11 can also include multiple structures such as a first fixing member and a second fixing member, and these multiple structures are connected in a detachable manner to form the mounting base 11. Both the first fixing member and the second fixing member can be structures such as fixing plates, fixing blocks, and fixing frames. That is, when the mounting base 11 is assembled together by multiple structures such as the first fixing member and the second fixing member, the groove 112 is located on one of the fixing members. Here, the specific structure of the mounting base 11 will not be limited or described in detail.

[0104] In some embodiments, see Figure 6 As shown, the detection device 1 also includes a detection component 13. The detection component 13 includes a transmitter 131, a receiver 132, and a detection component. The transmitter 131 and the receiver 132 are both disposed in the groove 112 and are arranged opposite to each other along the second direction, with a gap between them. The detection component and the receiver 132 are electrically connected. The transmitter 131 is used to transmit a signal to the receiver 132. The detection component is used to obtain at least one of the diameter and length of the tool 2.

[0105] It should be noted that the second direction is Figure 5 in the Y direction.

[0106] In this way, the diameter and length of tool 2 can be detected by the detection component 13. This allows for the detection of tool wear, spindle runout, diameter, and length in conjunction with the image acquisition unit 12. Furthermore, the detection functions of tool wear, spindle runout, diameter, and length can be integrated into a single structure. This allows for the simultaneous detection of tool wear, spindle runout, diameter, and length in all three dimensions, thereby improving the detection efficiency of tool 2 and ultimately increasing the uptime of the circuit board processing equipment.

[0107] It should be noted that the detection component is a grating ruler or encoder, and the transmitter 131 and receiver 132 need to work together with the detection component to detect the diameter and length of the tool 2. Of course, the detection component can also be other detection structures; here, no specific type of detection component is limited.

[0108] In some embodiments, the detection device 1 includes a first state and a second state. In the first state, the tool 2 is positioned outside the gap; in the second state, the tool 2 is positioned within the gap, and the tool 2 blocks the signal emitted by the transmitter 131 toward the receiver 132. When the tool 2 switches from the first state to the second state, the receiver 132 generates a first signal; when the tool 2 is in the second state and moves to a preset position along a first direction, the receiver 132 generates a second signal. The detection device is used to obtain the cutting length of the tool 2 based on the first and second signals.

[0109] It should be noted that the gap between the transmitter and receiver is the propagation path of the light beam emitted by the transmitter to the receiver. Furthermore, this application uses a grating ruler as an example to illustrate the detection device. The grating ruler is connected to the main shaft 3 and electrically connected to the receiver 132.

[0110] Specifically, the process of the detection device 1 detecting the blade length of the tool 2 is as follows: when the spindle 3 drives the tool 2 to move along the first direction toward the lens 121, when the tool 2 switches from the first state to the second state, the tool 2 blocks the signal emitted by the transmitter 131 toward the receiver 132. The receiver 132 generates the first signal, detects the first level change, and then starts counting the pulses of the grating ruler connected to the spindle 3.

[0111] Furthermore, as tool 2 continues to move along the first direction toward the preset position towards lens 121, receiver 132 generates a second signal. At this time, pulse counting of the grating ruler connected to the spindle 3 stops. Based on the first signal and the second signal, corresponding to the first level transition and the pulse count of the grating ruler connected to the spindle 3 within the interval between the first level transition and tool 2 reaching the preset position, the displacement of the grating ruler connected to the spindle 3 within that interval can be calculated. This displacement is the tool length of tool 2. This facilitates the detection of the tool length of tool 2 and improves the accuracy of the tool length detection.

[0112] In some embodiments, the spindle 3 can also drive the tool 2 to move relative to the mounting base 11 along a third direction. The detection device 1 further includes a third state, a fourth state, and a fifth state. In the third state, the tool 2 is located on one side of the gap along the third direction; in the fourth state, the tool 2 is located in the gap and is used to block the signal emitted by the transmitter 131 towards the receiver 132; in the fifth state, the tool 2 is located on the other side of the gap along the third direction. When the tool 2 switches from the third state to the fourth state, the receiver 132 generates a third signal; when the tool 2 switches from the fourth state to the fifth state, the receiver 132 generates a fourth signal. The detection element is used to obtain the tool diameter of the tool 2 based on the third signal and the fourth signal. Any two of the third direction, the first direction, and the second direction intersect.

[0113] It should be noted that the third party is... Figure 5 The Z direction in the equation.

[0114] Specifically, the process of the detection device 1 detecting the diameter of the tool 2 is as follows: when the spindle 3 drives the tool 2 to move along the third direction, when the tool 2 switches from the third state to the fourth state, the tool 2 blocks the signal emitted by the transmitter 131 toward the receiver 132. The receiver 132 generates a third signal, detects the second level change, and then starts counting the pulses of the grating ruler connected to the spindle 3.

[0115] Furthermore, when tool 2 switches from the fourth state to the fifth state, tool 2 no longer blocks the signal emitted by transmitter 131 towards receiver 132. Receiver 132 generates the fourth signal, detects the third level transition, and then stops counting the pulses of the grating ruler connected to spindle 3. Based on the pulse count of the third-direction grating ruler of the machine tool within the interval between the second and third level transitions corresponding to the third and fourth signals, the displacement of the third-direction grating ruler of the machine tool within that interval can be calculated. This displacement is the tool diameter of tool 2. In this way, the tool diameter of tool 2 can be conveniently detected, and the accuracy of the tool diameter detection can be improved.

[0116] The spindle 3 is mounted on the machine tool, which drives the spindle 3 to move.

[0117] Optionally, the detection component 13 is used to obtain the spindle runout value of the spindle 3.

[0118] Specifically, the process of detecting the spindle runout value of the spindle 3 by the detection device 1 is as follows: the receiving element 132 consists of two symmetrically arranged photodiodes, and the emitting element 131 simultaneously emits laser beams to the two photodiodes. When the spindle 3 is not runout, the two photodiodes absorb equal amounts of light, generating currents of the same magnitude. Furthermore, when the spindle 3 runsout, the runout of the tool 2 causes the two photodiodes to absorb unequal amounts of light, thereby generating currents of different magnitudes. The current difference between the two photodiodes after one revolution of the tool 2 is approximately a sine wave, and the spindle runout value of the spindle 3 can be calculated based on the amplitude of the current signal waveform.

[0119] In some embodiments, the image acquisition device 12 is used to acquire the diameter of the tool 2.

[0120] Thus, since the tool diameter and contour of tool 2 can be acquired through image acquisition device 12, the tool diameter and spindle runout value of tool 2 can be detected. This allows the tool diameter detection and spindle runout detection functions to be integrated into a single structure, enabling simultaneous detection of both tool diameter and spindle runout value. This improves the detection efficiency of tool 2 and increases the uptime of the circuit board processing equipment. Furthermore, directly acquiring the tool diameter of tool 2 through image acquisition device 12 facilitates operator inspection.

[0121] In some embodiments, the image acquisition unit 12 is used to acquire the amount of wear on the blade of the tool 2.

[0122] Thus, since the tool wear amount and the contour of tool 2 can be obtained through image acquisition device 12, the tool wear amount and spindle runout value of tool 2 can be detected. Furthermore, the tool wear amount detection function and the spindle runout value detection function can be integrated into one structure, and the tool wear amount and spindle runout value of spindle 3 can be detected at the same time, which can improve the detection efficiency of tool 2 and improve the utilization rate of circuit board processing equipment.

[0123] In some embodiments, see Figure 1 As shown, the detection device 1 also includes an air blowing component 14, which is disposed on the mounting base 11, and the air blowing component 14 and the groove 112 are spaced apart; the detection device 1 also includes an air blowing state. In the air blowing state, the air blowing port of the air blowing component 14 is disposed opposite to the tool 2 along a first direction.

[0124] In this way, air can be blown onto the surface of tool 2 by the air blowing component 14, thereby blowing away the chips on the surface of tool 2 and ensuring the accuracy of the detection data of tool 2.

[0125] In some embodiments, see Figure 1 As shown, the detection device 1 also includes a cover plate 15; the cover plate 15 is located on the side of the detection assembly 13 facing the tool 2, and along the direction of gravity of the mounting base 11, the cover plate 15 covers part of the groove 112.

[0126] Thus, the cover plate 15 can reduce the entry of external dust into the through hole 111, thereby reducing the contamination of the lens 121 by external dust and improving the detection accuracy. Furthermore, the cover plate 15 can protect the detection assembly 13 and the image acquisition unit 12. In some embodiments, the cover plate 15 can also provide auxiliary positioning for the tool 2, making the detection of the tool 2 more convenient.

[0127] In some embodiments, the detection device 1 further includes an opening and closing member; the opening and closing member is disposed in the through hole 111; the through hole 111 includes a first sub-through hole and a second sub-through hole that are connected, the first sub-through hole and the second sub-through hole are arranged along a first direction, the opening and closing member is disposed between the first sub-through hole and the second sub-through hole, and is used to connect or disconnect the first sub-through hole and the second sub-through hole.

[0128] Thus, when the lens 121 is in operation, the opening and closing mechanism opens, allowing the lens 121 to acquire the outline of the tool 2 and thus perform inspection of the tool 2. When the lens 121 is not performing inspection, the opening and closing mechanism closes, thereby preventing dust from falling onto the lens 121 and improving its anti-fouling effect.

[0129] In some embodiments, see Figure 7 As shown, the detection device 1 also includes a connecting assembly 16. The connecting assembly 16 includes a first connector 161 and a second connector 162. One side of the first connector 161 is connected to the side of the mounting base 11 facing the image acquisition unit 12. The second connector 162 surrounds the circumferential surface of the image acquisition unit 12 and is connected to the other side of the first connector 161.

[0130] In this way, the image acquisition device 12 and the mounting base 11 can be fixedly connected through the first connector 161 and the second connector 162, thereby avoiding the image acquisition device 12 from shaking or even falling off relative to the mounting base 11, and improving the stability and reliability of the connection between the image acquisition device 12 and the mounting base 11.

[0131] In some embodiments, one of the first connector 161 and the image acquisition device 12 is provided with a recess 1611 and the other is provided with a protrusion; the recess 1611 and the protrusion are fitted together.

[0132] Thus, on the one hand, the cooperation between the recessed portion 1611 and the protrusion improves the stability of the connection between the image acquisition unit 12 and the first connecting member 161, thereby further enhancing the stability and reliability of the connection between the image acquisition unit 12 and the mounting base 11. On the other hand, the cooperation between the recessed portion 1611 and the protrusion provides auxiliary positioning for the image acquisition unit 12, facilitating its acquisition of the contour of the tool 2. Furthermore, it facilitates reinstallation and repositioning of the image acquisition unit 12 during maintenance and replacement, saving installation and debugging time.

[0133] It is understood that the image acquisition device 12 can be directly connected to the first connector 161 via a threaded connection or other means, or the image acquisition device 12 can also be directly connected to the mounting base 11 via a threaded connection or other means. The specific installation and connection method between the image acquisition device 12 and the mounting base 11 can be changed according to actual usage requirements. Here, the connection method between the image acquisition device 12 and the mounting base 11 will not be described in detail.

[0134] Optionally, see Figure 5 As shown, the machine tool also includes a tool head fixing component 4, a tool holder 5, and a tool box 6. The mounting base 11 is connected to the tool head fixing component 4, and both the tool holder 5 and the tool box 6 are mounted on the tool head fixing component 4. The tool box 6 is used to store the tool 2. The tool holder 5 is used to transfer the tool 2, either by moving the tool 2 from the tool box 6 to the spindle 3, or by moving the tool 2 from the spindle 3 to the tool box 6, thus fulfilling different functional requirements for the tool 2.

[0135] As an optional implementation, the mounting base 11 and the cutter head fixing member 4 are threaded together. Of course, the mounting base 11 and the cutter head fixing member 4 can also be installed and connected in other ways according to actual usage requirements. Here, the installation and connection method of the mounting base 11 and the cutter head fixing member 4 is not limited. Similarly, the relative position of the mounting base 11 relative to the cutter head fixing member 4 is not limited.

[0136] As an alternative implementation, the detection device 1 can be applied to a single-axis circuit board processing equipment, or to a six-axis, eight-axis, twelve-axis or other multi-axis circuit board processing equipment, and the number of axes of the circuit board processing equipment is not limited.

[0137] Furthermore, a worktable base 7 is provided on the side of the cutter head fixing member 4 away from the tool. The worktable base 7 has a clearance area 71, and the detection device 1 is located within the clearance area 71, thereby improving the overall space utilization of the detection device 1 when applied to the tool 2. Of course, the detection device 1 and the tool 2 can be located in other positions on the worktable base 7 according to actual usage requirements. For example, the tool 2 can be located on the side closer to the operator, thereby avoiding the need to set up the clearance area 71 on the worktable base 7, thus improving the overall consistency of the worktable base 7.

[0138] In some embodiments, see Figure 7 As shown, the image acquisition device 12 also includes a power interface 122, which is spaced apart from the lens 121 and is used to connect to an external power source.

[0139] In this way, the image acquisition unit 12 can be charged or powered by an external power source, thereby ensuring the normal operation of the detection device 1.

[0140] In some embodiments, see Figure 7 As shown, the image acquisition device 12 also includes a data transmission interface 123, which is spaced apart from the lens 121. The data transmission interface 123 is used to transmit information about the outline of the tool 2 acquired by the lens 121.

[0141] In this way, the contour information of the tool 2 acquired by the image acquisition device 12 can be transmitted to the outside through the data transmission interface 123, which makes it convenient for the operator to process and store the data.

[0142] In some embodiments, see Figure 7 As shown, the image acquisition device 12 also includes an adjustment member 124, which is connected to the lens 121 and is used to adjust the distance between the lens 121 and the tool 2.

[0143] In this way, the adjustment component 124 can ensure the clarity and accuracy of the contour information of the tool 2 acquired by the lens 121, thereby improving the detection accuracy.

[0144] It is understood that the adjusting component 124 can be adjusted manually or automatically. Here, the specific adjustment method of the adjusting component 124 is not limited.

[0145] In some embodiments, the image acquisition device 12 further includes a seal that is fitted over the lens 121 and located between the inner wall of the lens 121 and the through hole 111.

[0146] In this way, dust can be prevented from entering through the gap between the lens 121 and the through hole 111 and contaminating the lens 121, thus keeping the lens 121 clean and improving the accuracy of the detection device 1.

[0147] In some embodiments, see Figure 8 As shown, the mounting base 11 is provided with an air hole 113, which is connected to the through hole 111, and the axial direction of the air hole 113 intersects with the axial direction of the through hole 111.

[0148] In this way, air can be blown into the through hole 111 through the air hole 113, thereby blowing away debris, dust and other impurities during the detection process from the through hole 111, thereby further preventing debris, dust and other impurities from contaminating the lens 121, and thus further improving the detection accuracy of the detection device 1.

[0149] Optionally, the vent 113 is oriented toward the tool 2, thereby providing stable air pressure in the direction of the lens 121 toward the tool 2 through the vent 113, which can stabilize the detection process and ensure accurate detection results.

[0150] Optionally, the through hole 111 can be a countersunk hole. This application does not limit the specific type of the through hole 111 or the number and location of the vents 113.

[0151] Secondly, see Figure 9 As shown, an embodiment of this application provides a detection system 8, including the detection device 1 described in the first aspect. The detection system 8 further includes a data processing unit 81 and a main control unit 82. The data processing unit 81 is electrically connected to the image acquisition unit 12 of the detection device 1, and is used to process and analyze the contour information of the tool 2 acquired by the image acquisition unit 12, and generate processing information, which includes at least one of the tool wear amount, spindle runout value, and tool diameter. The main control unit 82 is electrically connected to the data processing unit 81, receives the processing information generated by the data processing unit 81, and is used to determine whether the processing information is within a preset range.

[0152] Specifically, the process of the detection device 1 detecting the wear of the tool 2's cutting surface is as follows: the image acquisition unit 12 captures an image of the tool 2's cutting surface, and performs image processing such as noise reduction and grayscale processing on the captured image to improve its quality. Specifically, image processing is used to extract the tool 2's cutting surface features, including wear area and surface cracks. By comparing this with a standard cutting surface, the presence of defects is detected, thereby determining the degree of wear on the tool 2's cutting surface.

[0153] Furthermore, the data processing unit 81 processes and analyzes the contour information of the tool 2 acquired by the image acquisition unit 12, and generates processing information, which includes at least one of the tool wear amount, spindle runout value, and tool diameter. The main control unit 82 receives the processing information generated by the data processing unit 81 and determines whether the processing information is within the preset range of the processing information, thereby issuing an instruction to continue processing or replace the tool 2.

[0154] In this way, the wear of the tool face, the spindle runout, and the diameter of the tool 2 can be detected. Furthermore, the detection functions of the wear of the tool face, the spindle runout, and the diameter of the tool 3 can be integrated into one structure. The wear of the tool face, the spindle runout, and the diameter of the tool 2 can be detected at the same time, which can improve the detection efficiency of the tool 2 and increase the uptime of the circuit board processing equipment.

[0155] In addition, this application integrates the detection functions of tool wear, spindle runout, and tool diameter into one module. The main control unit 82 can promptly detect potential problems and take measures based on the detection results of tool 2, and automatically issue instructions such as replacing tool 2, which can realize intelligent and unmanned processing.

[0156] In some embodiments, see Figure 10As shown, the data processing unit 81 is electrically connected to the detection piece of the detection device 1; the data processing unit 81 is also used to process and analyze the information of the tool length dimension of the tool 2 obtained by the detection piece, and generate the tool length dimension. The main control unit 82 is also used to receive the tool length dimension generated by the data processing unit 81, and determine whether the tool length dimension is within the preset range of the tool length dimension.

[0157] Specifically, the process of the detection device 1 detecting the cutting length of the tool 2 is as follows: the cutting length of the tool 2 is detected by the detection component 13 to obtain the cutting length information of the tool 2.

[0158] Furthermore, the data processing unit 81 processes and analyzes the tool length information of the tool 2 obtained from the inspection piece, and generates the tool length dimension. The main control unit 82 receives the tool length dimension generated by the data processing unit 81, and determines whether the tool length dimension is within the preset range of the processed information, thereby issuing an instruction to continue processing or replace the tool 2.

[0159] In some embodiments, the data processing unit 81 is electrically connected to the detection element of the detection device 1; the data processing unit 81 is used to process and analyze the information on the tool diameter of the tool 2 obtained by the detection element, and generate the tool diameter. The main control unit 82 is also used to receive the tool diameter generated by the data processing unit 81, and determine whether the tool diameter is within a preset range.

[0160] Specifically, the process of the detection device 1 detecting the diameter of the tool 2 is as follows: the detection component 13 detects the diameter of the tool 2 and obtains the information of the diameter of the tool 2.

[0161] Furthermore, the data processing unit 81 processes and analyzes the tool diameter information of the tool 2 obtained from the inspection piece, and generates the tool diameter dimension. The main control unit 82 receives the tool diameter dimension generated by the data processing unit 81, and determines whether the tool diameter dimension is within the preset range of the processed information, thereby issuing an instruction to continue processing or replace the tool 2.

[0162] For example, see Figure 9 As shown, the data processing unit 81 is electrically connected to the image acquisition unit 12 of the detection device 1. It processes and analyzes the contour information of the tool 2 acquired by the image acquisition unit 12 and generates processing information, including the tool wear amount and spindle runout value. The main control unit 82 is electrically connected to the data processing unit 81, receives the processing information generated by the data processing unit 81, and determines whether the processing information is within a preset range. The data processing unit 81 processes and analyzes the tool length and diameter information of the tool 2 acquired by the inspection piece and generates the tool length and diameter dimensions. The main control unit 82 also receives the tool length and diameter dimensions generated by the data processing unit 81 and determines whether the tool length and diameter dimensions are within a preset range for the diameter dimensions.

[0163] Specifically, the process of the detection device 1 detecting the wear of the tool 2's cutting surface is as follows: the image acquisition unit 12 captures an image of the tool 2's cutting surface, and performs image processing such as noise reduction and grayscale processing on the captured image to improve its quality. Specifically, image processing is used to extract the tool 2's cutting surface features, including wear area and surface cracks. By comparing this with a standard cutting surface, the presence of defects is detected, thereby determining the degree of wear on the tool 2's cutting surface.

[0164] Furthermore, the data processing unit 81 processes and analyzes the contour information of the tool 2 acquired by the image acquisition unit 12, and generates processing information, including the tool wear amount and spindle runout value. The main control unit 82 receives the processing information generated by the data processing unit 81, and determines whether the processing information is within the preset range of the processing information, thereby issuing an instruction to continue processing or replace the tool 2.

[0165] Meanwhile, the process of the detection device 1 detecting the length and diameter of the tool 2 is as follows: the detection component 13 detects the length and diameter of the tool 2 to obtain information on the length and diameter of the tool 2.

[0166] Furthermore, the data processing unit 81 processes and analyzes the information on the tool length and diameter of the tool 2 obtained from the inspection piece, and generates the tool length and diameter dimensions. The main control unit 82 receives the tool length and diameter dimensions generated by the data processing unit 81, and determines whether the tool length and diameter dimensions are within the preset range of the processed information, thereby issuing an instruction to continue processing or replace the tool 2.

[0167] In this way, the wear of the tool face, spindle runout, tool length, and tool diameter can be detected. Furthermore, the detection functions of tool face wear, spindle runout, tool length, and tool diameter can be integrated into one structure. The wear of the tool face, spindle runout, tool length, and tool diameter can be detected at the same time, which can improve the detection efficiency of tool 2 and increase the uptime of the circuit board processing equipment.

[0168] For example, see Figure 10As shown, the data processing unit 81 is electrically connected to the image acquisition unit 12 of the detection device 1. It processes and analyzes the contour information of the tool 2 acquired by the image acquisition unit 12 and generates processing information, including the tool wear amount, spindle runout value, and tool diameter. The main control unit 82 is electrically connected to the data processing unit 81, receives the processing information generated by the data processing unit 81, and determines whether the processing information is within a preset range. The data processing unit 81 is also electrically connected to the detection piece of the detection device 1; the data processing unit 81 is also used to process and analyze the tool length information of the tool 2 acquired by the detection piece and generate the tool length dimension. The main control unit 82 is also used to receive the tool length dimension generated by the data processing unit 81 and determine whether the tool length dimension is within a preset range.

[0169] Specifically, the process of the detection device 1 detecting the wear of the tool 2's cutting surface is as follows: the image acquisition unit 12 captures an image of the tool 2's cutting surface, and performs image processing such as noise reduction and grayscale processing on the captured image to improve its quality. Specifically, image processing is used to extract the tool 2's cutting surface features, including wear area and surface cracks. By comparing this with a standard cutting surface, the presence of defects is detected, thereby determining the degree of wear on the tool 2's cutting surface.

[0170] Furthermore, the data processing unit 81 processes and analyzes the contour information of the tool 2 acquired by the image acquisition unit 12, and generates processing information, including the tool wear amount, spindle runout value, and tool diameter. The main control unit 82 receives the processing information generated by the data processing unit 81 and determines whether the processing information is within the preset range, thereby issuing an instruction to continue processing or replace the tool 2.

[0171] Meanwhile, the process of the detection device 1 detecting the cutting length of the tool 2 is as follows: the cutting length of the tool 2 is detected by the detection component 13 to obtain the cutting length information of the tool 2.

[0172] Furthermore, the data processing unit 81 processes and analyzes the tool length information of the tool 2 obtained from the inspection piece, and generates the tool length dimension. The main control unit 82 receives the tool length dimension generated by the data processing unit 81, and determines whether the tool length dimension is within the preset range of the processed information, thereby issuing an instruction to continue processing or replace the tool 2.

[0173] In this way, the wear of the tool face, spindle runout, tool length, and tool diameter can be detected. Furthermore, the detection functions of tool face wear, spindle runout, tool length, and tool diameter can be integrated into one structure. The wear of the tool face, spindle runout, tool length, and tool diameter can be detected at the same time, which can improve the detection efficiency of tool 2 and increase the uptime of the circuit board processing equipment.

[0174] In some embodiments, the detection system 8 further includes a computer 83 electrically connected to the main control unit 82 for displaying data processed by the main control unit 82.

[0175] In this way, the data processed by the main control unit 82 can be displayed on the computer 83, making it convenient for the operator to observe.

[0176] In some embodiments, the detection system 8 further includes a communication unit 84; the communication unit 84 is electrically connected to the main control unit 82 and is used to transmit data determined by the main control unit 82.

[0177] In this way, the data judged by the main control unit 82 can be transmitted through the communication unit 84, thereby realizing the data transmission for subsequent operation instructions.

[0178] In some embodiments, the detection system 8 further includes a storage unit 85; the storage unit 85 is electrically connected to the main control unit 82 and is used to store the data determined by the main control unit 82.

[0179] In this way, the data judged by the main control unit 82 can be stored in the storage unit 85 to avoid data loss.

[0180] Thirdly, a circuit board processing equipment for drilling or forming circuit boards, wherein the detection device 1 of the first aspect or the detection system 8 of the second aspect is integrated into the circuit board processing equipment.

[0181] In this way, the tool 2, which has been inspected by the detection device 1, can drill or shape the circuit board. On the one hand, this ensures the normal processing and preparation of the circuit board. On the other hand, the detection device 1 can ensure the accuracy of the detection of the tool 2's blade wear, tool diameter and tool length, as well as the spindle runout value of the spindle 3. This ensures the accuracy and stability of the tool 2 in the process of processing and preparing the circuit board, thereby improving the accuracy and reliability of circuit production and processing.

[0182] Fourthly, an embodiment of this application provides a detection method applied to the detection system 8 in the second aspect. The detection method includes the following steps:

[0183] S100: Controls the image acquisition unit of the detection system to acquire information about the contour of the tool.

[0184] S200: The data processing unit of the control and detection system processes and analyzes the information of the tool and its contour, and generates processing information, which includes at least one of the following: tool wear amount, spindle runout value, and tool diameter size.

[0185] S300: The main control unit of the control and detection system receives the processing information generated by the data processing unit and determines whether the processing information is within the preset range of the processing information.

[0186] In this way, the wear of the tool face, the spindle runout, and the diameter of the tool 2 can be detected. Furthermore, the detection functions of the wear of the tool face, the spindle runout, and the diameter of the tool 3 can be integrated into one structure. The wear of the tool face, the spindle runout, and the diameter of the tool 2 can be detected at the same time, which can improve the detection efficiency of the tool 2 and increase the uptime of the circuit board processing equipment.

[0187] It is understandable that when the main control unit 82 receives the processing information generated by the data processing unit 81 and determines that the processing information is within the preset range of the processing information, the main control unit 82 issues an instruction to continue processing, thereby performing subsequent detection of other functions or completing the final detection.

[0188] When the main control unit 82 receives the processing information generated by the data processing unit 81 and determines that the processing information is not within the preset range of the processing information, the main control unit 82 issues an instruction to replace tool 2 and ends the detection of tool 2.

[0189] It should be noted that during the actual use of tool 2 and spindle 3, due to the different service lives and wear levels of tool 2 and spindle 3, the actual service life of spindle 3 is significantly longer than that of tool 2. That is, the inspection cycle of spindle 3 is longer than that of tool 2. Therefore, it is not necessary to perform spindle runout detection every time tool 2 is replaced. Machine tool managers can preset the spindle runout detection cycle according to actual needs, and only need to detect the spindle runout value once within the spindle runout detection cycle. This reduces the inspection cost and time of inspection device 1, improves the inspection efficiency of inspection device 1, and reduces unnecessary inspections. Specifically, before the image acquisition unit 12 of the control inspection system 8 acquires the contour information of tool 2, the main control unit 82 pre-determines whether to detect the spindle runout value based on the spindle runout cycle. If it is not necessary to detect the spindle runout value, the tool wear level, tool diameter, and tool length are directly detected. If it is necessary to test the runout value of spindle 3, the runout value of spindle 3 should be tested first to see if it is qualified, and then the tool wear degree, tool diameter and tool length should be tested.

[0190] As an optional implementation, the detection method further includes: the spindle 3 clamps the tool 2 to be tested to the air blowing component 14 and cleans the tool 2.

[0191] Optionally, to ensure that tool 2 can be cleaned more thoroughly, tool 2 needs to be rotated when cleaning it with the air blower 14.

[0192] Optionally, for tools 2 with smaller diameters, to reduce dust on tools 2, after cleaning with the air blower 14, the tools 2 can be dusted with modeling clay. Specifically, modeling clay can be fixedly placed at the bottom of the air outlet of the air blower 14. After cleaning the tools 2 with air, the rotation stops, and the tools 2 are moved downwards to insert into the modeling clay to a certain depth. Then, the tools are moved upwards to remove the tools 2 from the modeling clay, thus achieving dust removal of the tools 2. This can further improve the cleanliness of the tools 2 and improve the product processing quality.

[0193] It is understood that the method of using modeling clay for dust removal in this embodiment is simple and easy to operate, and is merely an example of a dust removal method. This application may employ other dust removal methods for tool 2 according to actual usage requirements; therefore, no limitation is imposed on the dust removal method used for tool 2.

[0194] In some embodiments, the detection method further includes the following steps:

[0195] S400: Controls the detection system to obtain information on the tool length of the inspection piece.

[0196] S410: Control data processing unit processes the tool length information of the analysis tool and generates the tool length dimensions.

[0197] S420: The main control unit receives the tool length dimension generated by the data processing unit and determines whether the tool length dimension is within the preset range.

[0198] S500: Controls the detection system to obtain information on the tool diameter of the inspection piece.

[0199] S510: Control data processing unit processes the tool diameter information of the analysis tool and generates the tool diameter.

[0200] S520: The main control unit receives the tool diameter generated by the data processing unit and determines whether the tool diameter is within the preset range.

[0201] In this way, the detection of tool 2's face wear, spindle runout, tool diameter, and tool length can be achieved. Furthermore, the functions of detecting face wear, spindle runout, tool diameter, and tool length can be integrated into one structure, allowing for simultaneous detection of tool 2's face wear, spindle runout, tool diameter, and tool length. This improves the detection efficiency of tool 2 and increases the uptime of circuit board processing equipment.

[0202] For example, the specific operation process of this detection method is as follows: The main control unit 82 determines in advance whether to detect the yaw value of the main spindle 3 based on the yaw period of the spindle 3. If not, subsequent detection is performed directly. If yes, the image acquisition unit 12 of the detection system 8 acquires the contour information of the tool 2, the data processing unit 81 of the detection system 8 processes and analyzes the contour information of the tool 2, and generates the spindle yaw value. The main control unit 82 of the detection system 8 receives the spindle yaw value generated by the data processing unit 81 and determines whether the spindle yaw value is within the preset range of the spindle yaw value. If the detection result is qualified, subsequent detection is performed. If the detection result is unqualified, the detection process ends.

[0203] Furthermore, the image acquisition unit 12 of the control detection system 8 acquires information about the contour of the tool 2, and the data processing unit 81 of the control detection system 8 processes and analyzes the information about the contour of the tool 2 and generates the tool wear amount. Simultaneously, the detection unit of the control detection system 8 acquires information about the tool length and diameter of the tool 2, and the data processing unit 81 processes and analyzes the information about the tool length and diameter of the tool 2 and generates the tool length and diameter dimensions. The main control unit 82 receives the tool wear amount, tool length, and diameter dimensions generated by the data processing unit 81, and determines whether the tool wear amount, tool length, and diameter dimensions are within the preset range of the tool wear amount, tool length, and diameter dimensions, thereby ending the detection process or deciding whether to replace the tool.

[0204] For example, the specific operation process of this detection method is as follows: The main control unit 82 determines in advance whether to detect the yaw value of the main spindle 3 based on the yaw period of the spindle 3. If not, subsequent detection is performed directly. If yes, the image acquisition unit 12 of the detection system 8 acquires the contour information of the tool 2, the data processing unit 81 of the detection system 8 processes and analyzes the contour information of the tool 2, and generates the spindle yaw value. The main control unit 82 of the detection system 8 receives the spindle yaw value generated by the data processing unit 81 and determines whether the spindle yaw value is within the preset range of the spindle yaw value. If the detection result is qualified, subsequent detection is performed. If the detection result is unqualified, the detection process ends.

[0205] Furthermore, the image acquisition unit 12 of the control detection system 8 acquires information about the contour of the tool 2, and the data processing unit 81 of the control detection system 8 processes and analyzes the information about the contour of the tool 2, generating the tool wear amount and the tool diameter. Simultaneously, the detection unit of the control detection system 8 acquires information about the tool length of the tool 2, and the data processing unit 81 processes and analyzes the information about the tool length of the tool 2, generating the tool length dimension. The main control unit 82 receives the tool wear amount, tool length dimension, and tool diameter dimension generated by the data processing unit 81, and determines whether the tool wear amount, tool length dimension, and tool diameter dimension are within the preset range of the tool wear amount, tool length dimension, and tool diameter dimension, thereby ending the detection process or deciding whether to replace the tool.
