Abstract
Description
Technical Field
[0001] This application relates to the field of laser processing technology, and in particular to a galvanometer device and laser processing equipment. Background Technology
[0002] A galvanometer is a specialized motion device used in laser processing. A galvanometer device uses two or more galvanometers to reflect the laser beam, controlling its movement across the scanning plane to achieve precision machining, small-area processing, and other applications. Currently, the use of galvanometer devices for scanning processing has become the mainstream choice in the laser processing field due to its high speed, high precision, and high stability.
[0003] Currently, galvanometer devices typically employ a relatively enclosed structural design, integrating components such as the galvanometer motor, reflecting mirror, and drive circuit internally, while externally retaining power interfaces, command interfaces, laser inlet, and laser outlet. The power interface provides independent power to the galvanometer; the galvanometer receives external motion signals from the command interface and uses the drive circuit to adjust the movement of the galvanometer motor and reflecting mirror, ensuring that the incident laser, after passing through the reflecting mirror, exits the galvanometer at the desired position and angle.
[0004] Generally, galvanometer devices need to operate at high speeds for extended periods in harsh working environments such as high temperatures, strong magnetic fields, and dust. Their highly integrated optical, electrical, and mechanical precision components are quite sensitive and easily affected by physical impacts, power fluctuations, magnetic field interference, and their own aging. This can lead to reduced processing accuracy and efficiency, or even system malfunction, damage to workpieces, and endanger personal safety.
[0005] Typically, galvanometer devices either lack the ability to monitor the operational status of their internal components or connect to a host computer via a command interface protocol to view the component's status. However, this can negatively impact the performance of the galvanometer device and cause inconvenience for operators on-site. Utility Model Content

[0040] 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.

[0044] A galvanometer is a specialized motion device used in laser processing. A galvanometer device uses two or more galvanometers to reflect the laser beam, controlling its movement across a scanning plane to achieve precision machining, small-area processing, and other applications. Currently, galvanometer devices typically employ a relatively enclosed structural design, integrating the galvanometer motor, reflecting mirrors, and drive circuitry internally, while retaining external power interfaces.
[0045] Generally, galvanometer devices typically need to operate at high speeds for extended periods in harsh environments such as high temperatures, strong magnetic fields, and dust. Their highly integrated optical, electrical, and mechanical components are quite sensitive. Usually, galvanometer devices either lack the means to monitor the operating status of their internal components or connect to a host computer via a command interface protocol to view the status. However, this can negatively impact the performance of the galvanometer device and cause inconvenience for operators on-site.
[0046] For this reason, see Figure 1 and Figure 2 This application provides a galvanometer device 100. Figure 1 This is a schematic diagram of a galvanometer device 100 according to an embodiment of this application from a certain viewing angle. Figure 2 for Figure 1 A schematic diagram of the galvanometer device 100 shown from another perspective.
[0047] The galvanometer device 100 is used in laser processing equipment (not shown). The galvanometer device 100 can reflect the laser emitted by the laser (not shown) in the laser processing equipment to control the movement of the laser in the scanning plane, so as to complete applications such as precision processing and small-area processing.
[0048] Understandably, the galvanometer device 100 has a laser inlet (not shown) and a laser outlet (not shown). The laser emitted by the laser enters the galvanometer device 100 through the laser inlet, and the galvanometer device 100 reflects the laser at least once so that the laser can be emitted through the laser outlet for processing.
[0049] The type of laser processing equipment is not limited in principle. In this application, the laser processing equipment is a precision processing equipment or a small-format processing equipment. Of course, in other embodiments of this application, the laser processing equipment can be applied to laser material processing, biomedical detection, image and graphics processing, or other fields that require laser processing.
[0050] The galvanometer device 100 of this application facilitates monitoring of its operation and ensures its performance. Furthermore, it eliminates the need to connect the galvanometer device 100 to the host computer 200, making it convenient for on-site operation. The specific structure of a galvanometer device 100 according to one embodiment is described below.
[0051] See Figures 1 to 3 In one embodiment, the galvanometer device 100 includes a galvanometer housing 110, a drive assembly (not shown), and a display assembly 130. The drive assembly is disposed within the galvanometer housing 110; the drive assembly includes a drive plate 120, a galvanometer motor (not shown), and galvanometer lenses (not shown). The galvanometer motor is electrically connected to the drive plate 120, and the galvanometer lenses are disposed at the output terminal of the galvanometer motor. The display assembly 130 is at least partially located outside the galvanometer housing 110, and the display assembly 130 is electrically connected to the drive plate 120 for displaying relevant information recorded on the drive plate 120. Figure 3 for Figure 1 The functional block diagram of the galvanometer device 100 shown is shown.
[0052] The galvanometer housing 110 is the outer shell of the galvanometer device 100. All components of the galvanometer device 100 are housed within the galvanometer housing 110, giving the galvanometer device 100 a relatively enclosed structure. In this way, the galvanometer housing 110 can protect the internal components, preventing dust, moisture, and other contaminants from entering the interior of the galvanometer housing 110 and affecting the performance of the galvanometer device 100.
[0053] Furthermore, the galvanometer housing 110 has a laser inlet and a laser outlet that connect to the interior. The drive assembly is the power component of the galvanometer device 100, and is disposed within the galvanometer housing 110, corresponding to the laser inlet and the laser outlet. In this way, after the laser enters the galvanometer housing 110 from the laser inlet, the laser can be projected onto the drive assembly, which then reflects the laser, causing it to exit from the laser outlet.
[0054] Specifically, the drive assembly includes a drive board 120, a galvanometer motor, and galvanometer lenses. The drive board 120 is disposed in the galvanometer housing 110, the galvanometer motor is electrically connected to the drive board 120, and the galvanometer lenses are mounted on the output end of the galvanometer motor. After receiving a command signal, the drive board 120 can drive the galvanometer motor to control the movement of the galvanometer lenses.
[0055] The drive board 120 is the main control board of the galvanometer device 100, which can interact and control with the host computer 200 of the laser processing equipment, such as... Figure 4 As shown, Figure 4 for Figure 3 The diagram shows the functional block diagram of the interaction between the galvanometer device 100 and the host computer 200. The galvanometer motor is the power source for the drive components, and the galvanometer lens is a galvanometer that reflects the laser light and is located at the output end of the galvanometer motor.
[0056] The driver board 120 can receive command signals sent by the host computer 200, and then the driver board 120 feeds back the command signals to the galvanometer motor to achieve precise and rapid motion drive of the galvanometer motor. The galvanometer motor executes corresponding actions according to the command signals, thereby driving the galvanometer lens to rotate around a fixed axis according to a certain pattern to adjust the position of the galvanometer lens. By rotating the galvanometer lens, the emission direction of the laser is changed, so that the laser can be emitted at the desired angle and / or position after passing through the galvanometer lens, realizing full-plane scanning of the laser.
[0057] Understandably, since the drive board 120, the galvanometer motor, and the galvanometer lens are located inside the galvanometer housing 110, it is impossible to accurately monitor the working status of each component. Therefore, this application provides a display component 130 in the galvanometer device 100. The display component 130 is at least partially located outside the galvanometer housing 110 and is disposed on the outer surface of the galvanometer housing 110.
[0058] The display component 130 can be electrically connected to the driver board 120. In addition to controlling the movement of the galvanometer motor, the driver board 120 can also acquire relevant information about the driver board 120, the galvanometer motor, and the galvanometer lens, such as acquiring information about the movement (e.g., rotation, which will not be mentioned later) of the galvanometer lens, acquiring temperature information of the driver board 120 and / or the galvanometer motor, or acquiring information about the running time of the galvanometer motor (mentioned later), etc.
[0059] In this way, the drive board 120 can feed back the acquired relevant information to the display component 130, which in turn can display the relevant information. Thus, operators can intuitively and clearly understand the working status of each component inside the galvanometer device 100 by viewing the display component 130, enabling performance monitoring of each component and ensuring the performance of the galvanometer device 100. This eliminates the need for operators to monitor via the host computer 200, facilitating on-site operation.
[0060] Meanwhile, since operators no longer need to monitor through the host computer 200, the corresponding network signal lines are eliminated, the anti-interference function is not required, the impact of the external environment on high-speed network communication is avoided, and there is no need to set up a special command interface protocol, so that the driver board 120 can be adapted to the current control system without the need to design a special control system.
[0061] Moreover, the galvanometer device 100 does not require a dedicated interface and network protocol, thus reducing the hardware and software costs of the galvanometer device 100 and the complexity of its implementation scheme, thereby reducing the overall production cost of the galvanometer device 100, improving the response speed of internal signal transmission, and reducing the transmission failure rate.
[0062] The galvanometer device 100 of the above embodiment has a display component 130 disposed on the outside of the galvanometer housing 110. This display component 130 is electrically connected to the drive board 120 to display relevant information recorded on the drive board 120. In this way, the operator can see the relevant information recorded on the drive board 120 through the display component 130, and then determine the working status of each component of the galvanometer device 100 based on this information, facilitating monitoring of the operation of the galvanometer device 100 and ensuring its performance. Furthermore, monitoring through a host computer 200 is unnecessary, making on-site operation easier for the operator.
[0063] Optionally, the galvanometer motor can drive the galvanometer to rotate around a fixed axis according to a certain pattern. In one embodiment, there is one galvanometer lens, which is mounted on the output end of the corresponding galvanometer motor to reflect the laser.
[0064] Of course, in other embodiments of this application, the number of galvanometer lenses may be at least two, the number of galvanometer motors is correspondingly set to the number of galvanometer lenses, the multiple galvanometer lenses are arranged along the reflection path of the laser, and the galvanometer motor drives the corresponding galvanometer lens to move in order to adjust the laser emission angle.
[0065] See Figures 1 to 4 In one embodiment, the display assembly 130 includes a display component 131 and a data acquisition component 132. The display component 131 is disposed on the outside of the galvanometer housing 110. The data acquisition component 132 is electrically connected to the drive board 120 and the display component 131 to display relevant information recorded on the drive board 120 through the display component 131.
[0066] Display component 131 is a component that displays information related to the driver board 120 on display assembly 130. Display component 131 is located on the outside of galvanometer housing 110 and on the outer side of galvanometer housing 110. Furthermore, display component 131 is located on the side of galvanometer housing 110 facing the operator for easy viewing by the operator.
[0067] The acquisition component 132 is a signal transmission component of the display component 130. The acquisition component 132 is electrically connected to the driver board 120 and the display component 131. The acquisition component 132 can transmit the relevant information recorded on the driver board 120 to the display component 131. In this way, the display component 131 can display the status information of the driver component.
[0068] In this way, operators can intuitively and clearly obtain the working status of each component of the galvanometer device 100 through the display component 131, which facilitates the monitoring of the operation of the galvanometer device 100 and ensures its performance. At the same time, there is no need to connect the galvanometer device 100 to the host computer 200, which is convenient for operators to operate on-site.
[0069] In one embodiment of this application, the acquisition component 132 is a signal transmission line, which is electrically connected to the driver board 120 and the display component 131. The signal transmission line is used to feed back the relevant information recorded on the driver board 120 to the display component 131.
[0070] The signal transmission line is located inside the galvanometer housing 110. One end of the line is connected to the drive board 120, and the other end passes through the galvanometer housing 110 and connects to the display component 131. The signal transmission line enables signal transmission. When the drive board 120 acquires relevant information, it can transmit the relevant information to the display component 131 via the signal transmission line, and then the display component 131 displays the status information of the drive component.
[0071] In another embodiment of this application, the acquisition component 132 includes a receiving module and a transmitting module. The receiving module is disposed on the display component 131, and the transmitting module is disposed on the driver board 120. The transmitting module is transmittedly connected to the receiving module. The transmitting module is used to feed back the relevant information recorded on the driver board 120 to the receiving module, and then feed it back to the display component 131 through the receiving module.
[0072] The transmitting module is integrated into the driver board 120, and the receiving module is integrated into the display component 131. The transmitting module and the receiving module are wirelessly connected. After the driver board 120 collects relevant information, it can transmit the relevant information to the receiving module through the transmitting module. After receiving the relevant information, the receiving module displays the status information of the driving component through the display component 131.
[0073] Optionally, the transmitting module is a signal transmitter, and the receiving module is a signal receiver. Alternatively, the transmitting module can be a signal transmitting circuit integrated on the driver board 120, and the receiving module can be a signal receiving circuit integrated on the display component 131.
[0074] Of course, in other embodiments of this application, the acquisition component 132 may also be a signal transmitter or other component capable of data transmission.
[0075] In one embodiment, the display component 130 further includes an alarm component (not shown), which is integrated into the display component 131. The driver board 120 also has an alarm module (not shown), which stores preset data in advance. When the relevant information recorded on the driver board 120 exceeds the preset data, the alarm module can control the alarm component to display an alarm on the display component 131.
[0076] Understandably, the driver board 120 includes an alarm module, and the display component 130 also includes an alarm element, which is located on the display component 131. Furthermore, the alarm module is connected to the alarm element. The alarm module is electrically connected to the main control board, and it stores preset data, which represents the limit values of relevant data for each component of the driver assembly.
[0077] After the drive board 120 acquires relevant information, the alarm module can compare the information recorded on the drive board 120 with pre-stored preset data. If the relevant information is less than the preset data, it indicates that each component in the drive assembly is in normal condition, and the galvanometer device 100 can continue to operate.
[0078] If the relevant information is greater than or equal to the preset data, it indicates that at least one component in the drive assembly is in an over-limit working state. The alarm module then controls the alarm component to issue an alarm signal to alert the operator that the relevant component is abnormal. The operator can then stop the galvanometer device 100 or perform other actions.
[0079] In other words, if the relevant information recorded on the drive board 120 is within the preset data of the alarm module, the galvanometer device 100 maintains normal operation. If the relevant information recorded on the drive board 120 exceeds the preset data in the alarm module, the galvanometer device 100 will be shut down or subjected to other processing to ensure its performance. The types of preset data will be introduced later in conjunction with the specific types of relevant information.
[0080] Optionally, the alarm module is an alarm processor, which stores preset data in advance. Optionally, the alarm component is an indicator light, which uses different colors to display alarm prompts for different parts of the drive assembly. Of course, the alarm component can also be a buzzer, a flashing icon, or other components that can serve an alarm function.
[0081] See Figures 1 to 4 In one embodiment, the drive board 120 has a motion acquisition module (not shown) for acquiring motion data of the galvanometer lens. The motion acquisition module feeds back the motion data to the display component 131 through the acquisition component 132, so that the display component 131 displays the motion state of the galvanometer lens.
[0082] The motion acquisition module is integrated on the driver board 120. The motion acquisition module can acquire motion data of the galvanometer lens, such as the position and / or angle of the galvanometer lens, etc., and then the motion data acquired by the motion acquisition module is fed back to the display component 131. After processing the motion data, the display component 131 displays the motion state of the galvanometer lens on the display component 131.
[0083] In this way, the operator can intuitively determine the movement state of the galvanometer lens from the display component 131, so as to monitor the movement of the galvanometer lens and determine the state of laser movement, reset, stop and other steps based on the movement state of the galvanometer lens, so as to obtain information such as the movement state of the galvanometer lens during laser processing and ensure the accuracy of laser processing.
[0084] Optionally, the motion acquisition module is a camera, which takes pictures of the galvanometer lens to obtain relevant motion data of the galvanometer lens. Alternatively, the motion acquisition module can be connected to the galvanometer motor to detect the motor's motion information, thereby determining the motion data of the galvanometer lens based on this information.
[0085] In other embodiments of this application, the motion acquisition module may also be a scanner, a position sensor, or other components capable of acquiring motion data.
[0086] See Figures 1 to 4 In one embodiment, the drive board 120 further includes a temperature acquisition module (not shown), which is used to acquire temperature data of the drive board 120 and / or the galvanometer motor. The temperature acquisition module feeds back the temperature data to the display component 131 through the acquisition component 132, and displays the operating temperature of the drive board 120 and / or the galvanometer motor through the display component 131.
[0087] Understandably, without temperature monitoring of the galvanometer device 100, there could be safety hazards during its operation, such as overheating of the galvanometer motor and drive board 120. This application integrates a temperature acquisition module into the drive board 120. This module collects temperature data from the drive board 120 and the galvanometer motor during operation, and then feeds this data back to the display unit 131. The display unit 131 processes the temperature data and displays the operating temperatures of the drive board 120 and the galvanometer motor.
[0088] Understandably, the preset data in the alarm module can be preset temperature threshold data. If the operating temperature displayed by the display component 131 does not exceed the preset temperature threshold in the alarm module, that is, the operating temperature of the drive board 120 and the galvanometer motor is within its tolerance range, the alarm component will not issue an alarm prompt, and the display component 131 will normally display the operating temperature of the drive board 120 and the galvanometer motor.
[0089] When the operating temperature displayed on the display component 131 exceeds the preset temperature threshold in the alarm module, that is, when the operating temperature of the drive board 120 and the galvanometer motor exceeds the maximum temperature they can withstand, the alarm component will sound an alarm and feed the alarm signal back to the display component 131, so that the operator can take timely countermeasures to stop the galvanometer device 100 or perform other processing.
[0090] In this way, the temperature data of the drive board 120 and the galvanometer motor are collected in real time by the temperature acquisition module, and the operating temperature of the drive board 120 and the galvanometer motor is displayed in real time by the display component 131. This allows the operator to intuitively monitor the operating temperature of the drive board 120 and the galvanometer motor, ensuring the reliable operation of the drive board 120 and the galvanometer motor while preventing damage to the drive board 120 and the galvanometer motor due to high temperature, thus ensuring the performance of the drive board 120 and the galvanometer motor.
[0091] Optionally, the temperature acquisition module is a temperature sensor that detects the temperature data between the driver board 120 and the galvanometer motor. Alternatively, the temperature acquisition module can be a temperature sensing circuit on the driver board 120 or other components capable of temperature detection.
[0092] See Figures 1 to 4 In one embodiment, the drive board 120 further includes a time acquisition module (not shown), which is used to acquire the running time data of the galvanometer motor. The time acquisition module feeds back the running time data to the display component 131 through the acquisition component 132, and displays the running time of the galvanometer motor through the display component 131.
[0093] Understandably, if the running time of the galvanometer motor is not monitored, prolonged operation of the galvanometer device 100 may affect the service life of the galvanometer motor. This application integrates a time acquisition module into the drive board 120. This module can collect the running time data of the galvanometer motor and then feed the running time data back to the display component 131. After processing the running time data, the display component 131 displays the running time of the galvanometer motor.
[0094] Understandably, the preset data in the alarm module is the critical lifespan value of the galvanometer motor. If the running time of the galvanometer motor is not close to the critical lifespan value, it indicates that the lifespan of the galvanometer motor is within the normal range, and the galvanometer motor can drive the movement of the galvanometer lens normally. At this time, the alarm component will not issue an alarm prompt, and the display component 131 will normally display the running time of the galvanometer motor.
[0095] When the running time displayed on the display unit 131 exceeds the lifespan threshold in the alarm module, meaning the galvanometer motor needs to be replaced, the alarm unit will sound an alarm and send the alarm signal back to the display unit 131. The operator can then replace the galvanometer motor according to the alarm prompt.
[0096] In this way, the running time (lifespan) of the galvanometer motor is collected by the time acquisition module and displayed in real time by the display component 131, so that the operator can understand whether the lifespan of the galvanometer motor has reached the critical value and give sufficient time for replacement.
[0097] When the galvanometer motor reaches its critical lifespan, an alarm signal will be emitted and displayed on the screen. At this time, the operator can promptly replace the galvanometer motor based on the alarm signal, ensuring the laser's normal operating time, reducing the troubleshooting rate, and guaranteeing the performance of the galvanometer device 100.
[0098] Optionally, the time acquisition module is a time acquisition device such as a timer, which acquires the actual running time of the galvanometer motor. Of course, in other embodiments of this application, the time acquisition module may also be a time acquisition circuit on the driver board 120 or other components capable of acquiring running time.
[0099] See Figures 1 to 4 In one embodiment, the display component 131 is a display screen, which is used to display relevant information recorded on the drive board 120 in real time. In this embodiment, the display screen is disposed on the outer side of the galvanometer housing 110 and is electrically connected to the acquisition component 132.
[0100] The display screen can show the motion posture of the galvanometer lens, the operating temperature of the galvanometer motor and / or drive board 120, and the running time of the galvanometer motor. This allows operators to intuitively determine the operating status of the drive components, facilitating operation of the galvanometer device 100.
[0101] Understandably, the motion of the galvanometer lens affects the laser reflection angle. By displaying the motion of the galvanometer lens on the screen, the operator can intuitively see the actual motion of the galvanometer lens and thus the reflection path of the laser by the galvanometer lens, so that the laser is emitted at the desired position and angle after passing through the galvanometer lens.
[0102] The operating temperatures of the drive board 120 and the galvanometer motor affect their performance. By displaying the operating temperatures of the drive board 120 and the galvanometer motor on the screen, operators can visually see the actual operating temperatures and control the galvanometer device 100 to operate or stop based on these temperatures.
[0103] The operating time of the galvanometer motor affects its performance. By displaying the motor's operating time on the screen, operators can visually see the actual running time and control the galvanometer device 100 to operate or stop based on this actual operating time.
[0104] Meanwhile, the display screen can also display alarm information, with the alarm component integrated into the screen. When the relevant information recorded on the driver board 120 exceeds the preset data, the alarm component can display an alarm on the screen, such as flashing an alarm icon or displaying alarm text prompts.
[0105] Optionally, the display screen is a touch screen. This allows the operator to control the galvanometer motor by touching the screen. Of course, in other embodiments of this application, the display screen can also be a conventional display screen, with related operation controls achieved through operation buttons.
[0106] In other embodiments of this application, the display component 131 is an indicator light or a digital tube, which displays the relevant information recorded on the driver board 120 in real time through the display status of the display screen or the digital tube. The indicator light can display the working status of the driver component through different colors or different patterns, and the relevant status of the driver component can also be displayed through the combination of digital tubes. Of course, the display component 131 can also be other components capable of displaying the working status of the driver component.
[0107] See Figures 1 to 4 In one embodiment, the display component 130 further includes a support member 133, which is disposed on the side of the display component 131 facing the galvanometer housing 110 and supports the display component 131 on the galvanometer housing 110.
[0108] The support member 133 is disposed on the outside of the galvanometer housing 110 and supports the display member 131 so that the display member 131 can be installed on the outer side of the galvanometer housing 110. The support member 133 facilitates the installation of the display member 131 so that the display member 131 is partially installed on the galvanometer housing 110.
[0109] Of course, the support member 133 can also rotatably support the display member 131, so that the display member 131 can rotate relative to the support member 133 to adjust the angle of the display member 131 to meet the operator's usage needs at different angles.
[0110] Optionally, the support component 133 is a support frame. Of course, in other embodiments of this application, the support component 133 may also be a support plate, a support column, or other structures that can provide support.
[0111] See Figures 1 to 4 In one embodiment, the galvanometer device 100 further includes a communication interface (not shown), which is electrically connected to the drive board 120. The drive board 120 is electrically connected to the host computer 200 via the communication interface. The communication interface is the interface connecting the galvanometer device 100 and the host computer 200.
[0112] A communication interface is located in the galvanometer housing 110 and electrically connected to the drive board 120. The galvanometer device 100 also includes a connecting cable, one end of which is plugged into the communication interface and the other end into the host computer 200. In this way, the host computer 200 can send command signals to the drive board 120 through the communication interface via the connecting cable. Thus, the drive board 120 can control the galvanometer motor according to the command signals, so that the galvanometer motor drives the galvanometer lens to move.
[0113] After the host computer 200 sends the command signals to be executed, such as position information, to the drive board 120 through the communication interface, the drive board 120 can also feed back the current position and current speed information of the galvanometer lens to the host computer 200 so that the operator can check the working status of the galvanometer device 100.
[0114] Furthermore, after receiving instructions from the host computer 200, the driver board 120 can calculate the current control quantity according to a suitable correction algorithm and control the galvanometer motor to work. Of course, the driver board 120 can also feed back the recorded relevant information to the host computer 200 via the communication interface and connection cable, so that the operator at the host computer 200 can intuitively see the working status of the drive component.
[0115] See Figures 1 to 4 In one embodiment, the galvanometer device 100 further includes a cooling pipe 140, which is disposed on the inner and outer sides of the galvanometer housing 110 and connected to form a cooling circuit. The cooling pipe 140 is used to cool the drive plate 120, the galvanometer motor, and the galvanometer housing 110.
[0116] The cooling pipe 140 is partially located on the outside of the galvanometer housing 110 and partially on the outside of the galvanometer housing 110. The cooling pipe 140 is connected to form a cooling circuit. Coolant flows in the cooling pipe 140. The coolant can absorb the temperature of the drive plate 120, the galvanometer motor and the galvanometer housing 110 to physically cool the drive plate 120, the galvanometer motor and the galvanometer housing 110.
[0117] The coolant is kept at a low temperature inside the galvanometer housing to cool the drive plate 120, the galvanometer motor, and the galvanometer housing 110. The absorbed heat flows through the cooling pipe 140 to the outside of the galvanometer housing 110, is cooled by a refrigerator, and then returns to the inside of the galvanometer housing 110 through the cooling pipe 140, thus repeating the cycle to ensure the cooling effect.
[0118] When the galvanometer device 100 operates continuously, it generates a high temperature of up to 50°C. This temperature will affect the performance and lifespan of the drive board 120 and the galvanometer motor. After the drive board 120 and the galvanometer motor are continuously cooled by the cooling pipe 140, the temperature of the drive board 120 and the galvanometer motor is reduced, ensuring the usability, accuracy and lifespan of the galvanometer motor, and ensuring the performance and lifespan of the drive board 120.
[0119] The galvanometer device 100 of this application has a display component 130 disposed on the outside of the galvanometer housing 110. The display component 130 is electrically connected to the drive board 120 to display relevant information recorded on the drive board 120. In this way, the operator can see the relevant information recorded on the drive board 120 through the display component 130, and then judge the working status of each component of the galvanometer device 100 based on the relevant information, which facilitates the monitoring of the operation of the galvanometer device 100 and ensures the performance of the galvanometer device 100.
[0120] In this way, the galvanometer device 100 can intuitively observe the various states of each component of the drive assembly during the laser processing through the display component 131, enhancing the intuitiveness of the status of the core components inside the galvanometer device 100. If the galvanometer device 100 malfunctions, the operator can immediately perform preliminary fault tracing through the display component 131, improving the fault elimination rate and increasing the production time of the laser processing equipment.
[0121] Meanwhile, the galvanometer device 100 does not require a separate network communication signal line, anti-interference function, or dedicated interface and network protocol, which reduces hardware and software costs, reduces the complexity of the implementation scheme of the galvanometer device 100, and thus reduces the overall cost of the galvanometer device 100.
[0122] like Figure 4As shown, this application also provides a laser processing device, which includes a host computer 200, a laser, and a galvanometer device 100 as described in any of the above embodiments. The input terminal of the galvanometer device 100 is connected to the output terminal of the laser, and the galvanometer device 100 is capable of adjusting the laser processing position of the laser. The host computer 200 is communicatively connected to the galvanometer device 100 and the laser.
[0123] After the laser processing equipment of this application adopts the galvanometer device 100 of the above embodiment, the working status of the galvanometer device 100 can be monitored during the laser processing to ensure the performance of the galvanometer device 100 and improve the processing efficiency.
[0124] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0125] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
