Description

Technical Field

[0001] This invention relates to the field of dental carving and milling machines, and more specifically, to an intelligent dental carving and milling machine and its control method. Background Technology

[0002] Currently, dental milling machines for tooth processing employ a user-friendly, "foolproof" operation. Once the machine receives the CNC (Computational Numerical Control) file via a transmission medium, pressing the start button begins operation, which continues until processing is complete. However, operators are often some distance from the machine, making it difficult to monitor the progress and status, requiring frequent checks and increasing unnecessary labor and time costs. Furthermore, if unexpected events occur during processing (such as insufficient compressed air pressure or tool breakage), operators cannot be notified promptly to prevent protective shutdowns and further damage.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0030] The following describes an intelligent dental carving and milling machine and its control method according to some embodiments of the present invention.

[0031] The first aspect of this invention provides an intelligent dental milling machine, such as... Figures 1 to 5As shown, it includes: a housing with a cavity inside; a controller 10 located within the cavity and connected to the housing; an X-axis movement assembly 20 electrically connected to the controller 10 and located within the cavity; a Z-axis movement assembly 30 electrically connected to the controller 10 and located within the cavity; a cutting axis connected to the output end of the Z-axis movement assembly 30, with a cutting tool mounted on the cutting axis for carving denture blanks; and a Y-axis movement assembly 40 electrically connected to the controller 10. The output end of the moving component 40 is connected to the Z-axis moving component 30. The Y-axis moving component 40 is located inside the cavity and can move along a third direction. A first A-axis moving component 50 is electrically connected to the controller 10. The output end of the first A-axis moving component 50 is equipped with a first denture clamp, which cooperates with the cutting axis to dry-cut the denture blank. A second A-axis moving component 60 is electrically connected to the controller 10. The output end of the second A-axis moving component 60 is equipped with a second denture clamp, which cooperates with the cutting axis to dry-cut the denture blank. The shaving shaft is used for wet cutting of the denture blank; the B-axis moving assembly 70 has its first end connected to the first A-axis moving assembly 50 and its second end connected to the second A-axis moving assembly 60. The B-axis moving assembly 70 is connected to the X-axis moving assembly 20 and is used to drive the first A-axis moving assembly 50 and the second A-axis moving assembly 60 to rotate; multiple temperature sensors 80 are mounted on the X-axis moving assembly 20 and the Y-axis moving assembly 40, respectively, and are electrically connected to the controller 10. Connect; there are multiple actuators 90, which are respectively installed on the X-axis moving assembly 20 and the Y-axis moving assembly 40. The actuators 90 are electrically connected to the controller 10 and are used for heating; in the initial state, the X-axis moving assembly 20 is used to drive the B-axis moving assembly 70 to move along the X-axis direction C, the Y-axis moving assembly 40 is used to drive the Z-axis moving assembly 30 to move along the Y-axis direction A, the Z-axis moving assembly 30 is used to drive the cutting axis to move along the Z-axis direction B, and the first A-axis moving assembly 50 and the second A-axis moving assembly 60 are used to rotate around the X-axis direction C.

[0032] This invention provides an intelligent dental milling machine. In the initial state, the movement direction of the output end of the X-axis moving component 20 is defined as the X-axis direction CC, the movement direction of the output end of the Y-axis moving component 40 is defined as the Y-axis direction A, and the movement direction of the output end of the Z-axis moving component 30 is defined as the Z-axis direction B. Based on the X-axis direction C, Y-axis direction A, and Z-axis direction B, coordinate systems are established at the output ends of the first A-axis moving component 50 and the second A-axis moving component 60, respectively. This allows the first denture clamp on the output end of the first A-axis moving component 50 and the second denture clamp on the output end of the second A-axis moving component 60 to rotate around the X-axis direction C.

[0033] Based on this, the first end of the B-axis moving component 70 is connected to the first A-axis moving component 50, and the second end of the B-axis moving component 70 is connected to the second A-axis moving component 60. Thus, the B-axis moving component 70 can drive the first A-axis moving component 50 and the second A-axis moving component 60 to rotate. It should be noted that when the first A-axis moving component 50 or the second A-axis moving component 60 rotates, its coordinate system will also rotate accordingly.

[0034] When the denture blank needs to be processed, the X-axis moving component 20 drives the B-axis moving component 70 to move, which in turn drives the first A-axis moving component 50 and the second A-axis moving component 60 to the required height. Then, the Y-axis moving component 40 drives the Z-axis moving component 30 to move along the Y-axis direction A, so that the Z-axis moving component 30 reaches the front of the first or second denture fixture. The Z-axis moving component 30 drives the cutting axis to move along the Z-axis direction B, and then the cutting tool on the cutting axis processes the denture blank. At the same time, the B-axis moving component 70 can also drive the first A-axis moving component 50 and the second A-axis moving component 60 to rotate. The first A-axis moving component 50 and the second A-axis moving component 60 are used to rotate around the X-axis direction C to achieve processing at different positions of the denture blank. Through multi-axis collaborative positioning, the tool is accurately positioned in three-dimensional space, which can accurately reach the position of the denture blank that needs to be processed, effectively avoiding positional deviation during the processing and ensuring processing accuracy.

[0035] Furthermore, multiple temperature sensors 80 are respectively installed on the X-axis moving component 20 and the Y-axis moving component 40, thereby enabling the temperature of the X-axis moving component 20 and the Y-axis moving component 40 to be obtained through multiple temperature sensors 80. Then, the controller 10 controls the temperature rise of the execution component to keep the overall system accuracy value in the most stable range.

[0036] By installing multiple temperature sensors 80, the system can monitor the temperature changes of these key components in real time, reduce system errors caused by temperature changes, and thus improve the overall stability and reliability of the system.

[0037] Specifically, the communication module is electrically connected to the controller 10.

[0038] Furthermore, in some embodiments of the present invention, such as Figure 3 As shown, the X-axis moving assembly 20 includes a first substrate 202 and an X-axis servo motor 204. The first substrate 202 is connected to the X-axis servo motor 204, which is located on the first side of the first substrate 202. A temperature sensor 80 is connected to the first substrate 202 and is located on the second side of the first substrate 202 away from the X-axis servo motor 204. An actuator 90 is connected to the first substrate 202 and is located on the third and fourth sides of the first substrate 202.

[0039] In this embodiment, the X-axis servo motor 204 is located on the first side of the first substrate 202, the temperature sensor 80 is located on the second side of the first substrate 202 away from the X-axis servo motor 204, and the actuator 90 is connected to the first substrate 202. The actuator 90 is located on the third and fourth sides of the first substrate 202, respectively. Thus, when the temperature sensor 80 detects that the temperature is not in the most stable range, the actuator 90 can be controlled to heat up to ensure the stability and reliability of the system temperature.

[0040] Furthermore, in some embodiments of the present invention, the Y-axis movement assembly 40 includes a second substrate 402 and a Y-axis servo motor. The second substrate 402 is connected to the Y-axis servo motor. A temperature sensor 80 is connected to the second substrate 402 and is located on one side of the second substrate 402. An actuator 90 is connected to the second substrate 402 and is located on the side of the second substrate 402 away from the Y-axis servo motor.

[0041] In this embodiment, the temperature sensor 80 is located on one side of the second substrate 402, and the actuator 90 is located on the side of the second substrate 402 away from the Y-axis servo motor. Thus, when the temperature sensor 80 detects that the temperature is not in the most stable range, the actuator 90 can be controlled to heat up to ensure the stability and reliability of the system temperature.

[0042] Furthermore, in some embodiments of the present invention, an X-axis servo driver is electrically connected to an X-axis moving component 20 and a controller 10, with the X-axis moving component 20 located within a cavity; a Y-axis servo driver is electrically connected to a Y-axis moving component 40 and a controller 10, with the Y-axis moving component 40 located within a cavity; a Z-axis servo driver is electrically connected to a Z-axis moving component 30 and a controller 10, with the Z-axis moving component 30 located within a cavity; a first A-axis servo driver is electrically connected to a first A-axis moving component 50 and a controller 10, with the first A-axis moving component 50 located within a cavity; and a second A-axis servo driver is electrically connected to a second A-axis moving component 60 and a controller 10, with the second A-axis moving component 60 located within a cavity.

[0043] Furthermore, in some embodiments of the present invention, a frequency converter is located inside the cavity and is electrically connected to the controller 10; a pressure sensor is located inside the cavity and is electrically connected to the controller 10.

[0044] A second aspect of the present invention provides a control method for an intelligent dental milling machine, such as... Figure 6 As shown, the intelligent dental milling machine used in any of the above embodiments includes:

[0045] Step 102: Initialize the controller 10. The controller 10 acquires temperature parameters, the first status code of the frequency converter, the second status code of the servo drive group, and the status information of the NC task.

[0046] Step 104: Based on the temperature parameters, determine whether to execute the first protection action;

[0047] Step 106: Based on the first status code, determine whether to execute the second protection action;

[0048] Step 108: Based on the second status code, determine whether to execute the third protection action;

[0049] Step 110: Based on the status information of the NC task, determine whether to execute the fourth protection action.

[0050] This invention provides a control method for an intelligent dental milling machine. First, the controller 10 is initialized. The controller 10 acquires temperature parameters through the temperature sensor 80. At the same time, the controller 10 acquires the first status code of the frequency converter, the second status code of the servo drive group, and the status information of the NC task.

[0051] Then, the status of the intelligent dental milling machine is judged sequentially based on temperature parameters, the first status code, the second status code, and the status of the NC task, and corresponding protection actions are executed based on the judgment results. The protection actions include the first protection action, the second protection action, the third protection action, and the fourth protection action.

[0052] Temperature parameters are obtained through temperature sensor 80 to trigger protective actions, ensuring stability and accuracy during processing. Simultaneously, the status of the engraving and milling machine is determined based on monitoring data, and corresponding protective actions (such as first, second, third, and fourth protection actions) are executed, ensuring safe operation of the equipment under different conditions and improving its reliability.

[0053] Furthermore, in some embodiments of the present invention, determining whether to perform a first protection action based on temperature parameters includes: determining whether the temperature parameters are within a preset temperature range; if the temperature parameters are within the preset temperature range, determining that the temperature is normal; otherwise, the actuator group 90 performs the first protection action; wherein, the preset temperature range is 28°C to 50°C.

[0054] In this embodiment, it is determined whether the temperature parameter is within a preset temperature range. If the temperature parameter is within the preset temperature range, the temperature is determined to be normal; otherwise, the actuator group 90 performs the first protection action. The preset temperature range is 28°C to 50°C.

[0055] It should be noted that due to the material properties of the metal bed in a dental milling machine, the overall system accuracy is most stable between 30°C and 50°C. Therefore, setting the lower limit of the preset temperature range to 30°C could lead to premature execution of the first protection action. Conversely, setting the temperature too low could result in inaccuracies. Therefore, this invention uses 28°C as the lower limit of its preset temperature range. This ensures timely response while avoiding delayed execution of the first protection action due to an excessively low lower limit, thus achieving a balance between cost, overall power consumption, and temperature uniformity.

[0056] Specifically, the first protection action includes: when the temperature parameter is below 28°C, the controller 10 controls the actuator 90 to heat up until the temperature parameter detected by the temperature sensor 80 is greater than 28°C; when the temperature parameter is above 28°C, the controller 10 controls the actuator 90 to shut off heating.

[0057] Specifically, when the temperature parameter is lower than the lower limit of the preset temperature range (i.e., 28°C) and the difference between the temperature parameter and the lower limit of the preset temperature range exceeds a preset threshold, the device temperature is determined to be too low. The controller 10 controls the actuator 90 to reach a first voltage to achieve rapid heating. If the temperature parameter is lower than the lower limit of the preset temperature range (i.e., 28°C) and the difference between the temperature parameter and the lower limit of the preset temperature range does not exceed the preset threshold, the device temperature is determined to be close to the preset temperature range. The controller 10 controls the actuator 90 to reach a second voltage to achieve slow heating. The first voltage is greater than the second voltage. (Preferably, the first voltage is much greater than the second voltage.)

[0058] Specifically, when the temperature parameter is lower than the upper limit of the preset temperature range (i.e., 50°C), the controller 10 controls the actuator 90 to shut down, and the device recovers to the preset temperature range by self-heating.

[0059] Specifically, the controller 10 can selectively shut down the corresponding actuator 90 based on the signals transmitted from different temperature sensors 80, thereby improving overall flexibility.

[0060] Furthermore, in some embodiments of the present invention, determining whether to execute a second protection action based on a first status code includes: determining whether the first status code is zero; if the first status code is zero, determining that the device status is abnormal; obtaining a first error code; sequentially analyzing the correlation between the first error code and voltage, load current, and short-circuit fault to obtain a first abnormal element; and executing a second protection action based on the first abnormal element; otherwise, determining that the device status is normal.

[0061] Specifically, the second protection action includes: when any of the following occurs: inverter overcurrent, motor running overcurrent, inverter overheating, inverter phase loss, inverter input voltage too high, inverter input phase loss, and motor overload, the output is stopped and an error message is broadcast verbally.

[0062] Furthermore, in some embodiments of the present invention, determining whether to execute a third protection action based on the second status code includes: sequentially determining whether the second status codes of all servo drives in the servo drive group are zero; if the second status code of any servo drive is zero, then determining that the device status is abnormal; obtaining a second error code; sequentially analyzing the correlation between the second error code and voltage, load current and short circuit fault to obtain a second abnormal element; and executing a third protection action based on the second abnormal element; otherwise, determining that the device status is normal.

[0063] Furthermore, in some embodiments of the present invention, determining whether to execute a fourth protection action based on the state of the NC task includes: sequentially analyzing the correlation between the state of the NC task and start, pause, completion, and abnormal interruption to obtain the state text of the NC task; obtaining a protection instruction based on the state text; and executing the fourth protection action based on the protection instruction.

[0064] Specifically, the fourth protection action includes: when the motion axis exceeds the range, an error message will pop up on the controller 10 screen; when the NC task is in the paused state, the operation will be paused; when the NC task is in the stopped state, the operation will be stopped.
