[0017] The above and other objects, features and advantages of the present invention will become more apparent through a more detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings, wherein like reference numerals generally represent like components throughout the exemplary embodiments of the present invention.
[0018] Figure 1 A schematic flow chart of an interactive CNC machine tool maintenance system according to an embodiment of the present invention is shown. DETAILED DESCRIPTION
[0019] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.
[0020] An interactive CNC machine tool maintenance method, comprising: S1. Establish a three-dimensional model of the machine tool and the preset thresholds and maintenance videos corresponding to each component; S2. Collecting real-time wear information of various components of the machine tool and recording it as dynamic parameters; S3. Compare the dynamic parameters and the preset thresholds, and update the prompt information according to the comparison results; S4. If the prompt information shows that it is qualified, the operation history information is recorded; If the prompt message shows that it is unqualified, repair it according to the three-dimensional model and the repair and maintenance video, and repeat S2-S4 after the repair.
[0021] Specifically, based on the preset threshold, the real-time dynamic parameters of the machine tool are collected for comparison to confirm whether the status of the machine tool requires inspection and maintenance. A prompt message displays the comparison result. If the machine tool is qualified after inspection, the inspection record is directly recorded. If the machine tool is unqualified, the qualification is repeatedly confirmed after inspection. If the machine tool is qualified, the inspection record is recorded again. The inspection record is retained in the form of operation history information for easy query.
[0022] During maintenance, the user can trigger the 3D model or maintenance video according to the prompt information to guide the maintenance. The video teaching with 3D simulation guidance can ensure that the maintenance is carried out smoothly.
[0023] Furthermore, the prompt information is displayed in a virtual key mode through the display screen.
[0024] In this embodiment, the preset threshold value includes warning interval data, and the plurality of prompt information are arranged in order. The closer the dynamic parameter is to the upper limit value of the warning interval data, the higher the corresponding prompt information is ranked.
[0025] Specifically, the components are sorted according to the severity of wear, with the most severely worn components being placed first.
[0026] In this embodiment, the preset threshold value includes historical time data, which is used to confirm the maintenance time interval during regular maintenance or irregular maintenance.
[0027] Specifically, historical time data is used to record operation times, allowing for scheduled maintenance without alarms. Regular maintenance can also prompt a pop-up alert when due. Regular maintenance can also trigger a self-check or update a prompt after a self-check is triggered, updating the machine status after scheduled maintenance. Regular maintenance does not trigger an alarm, so components are sorted and displayed based on the time until the next maintenance, with components with shorter intervals appearing higher in the list.
[0028] Furthermore, irregular maintenance can also be performed. For irregular maintenance, only the corresponding component name or project name is displayed, and the maintenance time can be recorded after the irregular maintenance.
[0029] In this embodiment, the operation history information includes personnel information, time information, and operation item information.
[0030] Specifically, the operator information during maintenance is recorded to facilitate responsibility tracking.
[0031] like Figure 1 As shown, the present invention also provides an interactive CNC machine tool maintenance system, comprising: The acquisition module collects wear information of various components of the machine tool through multiple sensors. The wear information is a dynamic parameter. A first storage module stores a three-dimensional model, data parameters, and maintenance videos corresponding to the machine tool, wherein the data parameters are preset thresholds; a processing module connected to the first storage module and the acquisition module, configured to compare the dynamic parameter with a preset threshold value and output corresponding prompt information according to a difference between the dynamic parameter and the preset threshold value; A display module is connected to the processing module and is used to interact with the processing module to display prompt information of the processing module and corresponding maintenance videos; The second storage module is electrically connected to the display module and is used to store operation history information.
[0032] Specifically, based on a preset threshold, the real-time dynamic parameters of the machine tool are collected and compared to determine whether the machine tool's status requires maintenance. The display module displays the comparison results through prompt information. If the machine tool passes the maintenance, the maintenance record is directly recorded. If the machine tool fails the maintenance, the machine tool is re-confirmed after the maintenance, and the maintenance record is recorded again after passing the maintenance. The maintenance record is retained as operation history information for easy query. Maintenance personnel can browse the operation history information recorded in the second storage module by browsing the records, and then confirm the past maintenance / maintenance status, which is suitable for regular or irregular maintenance.
[0033] When maintenance is required, the 3D model or maintenance video can be triggered according to the prompt information to guide the maintenance. The video teaching with 3D simulation guidance ensures that the maintenance is carried out smoothly.
[0034] In this embodiment, the display module includes: Playback area: The playback area is used to display 3D models and maintenance videos. Operators can rotate and zoom in and out of the 3D models. Function area: The function area is used to display dynamic parameters, preset thresholds, and adjust preset thresholds; Alarm area: The alarm area is used to display prompt information. By interacting with the prompt information, the corresponding maintenance video can be triggered.
[0035] Specifically, the display module is a display screen, which can be directly touched to modify parameters or configured for use with a keyboard and mouse. Different contents are displayed in partitions to facilitate personnel to identify operations.
[0036] In this embodiment, the prompt information includes a normal state and a highlighted state, which are used to indicate qualified and unqualified respectively.
[0037] Specifically, the prompt information is displayed in the display module in the form of a button module, and different colors or brightness are used to distinguish whether it is an alarm state, thereby facilitating confirmation of whether the component needs inspection and maintenance.
[0038] In this embodiment, the prompt information also includes a flashing state, which is used to indicate that the application is unqualified and has not been processed within the specified time limit.
[0039] Specifically, when it is determined to be unqualified and a maintenance prompt is given, if it has not been maintained for a long time, it will be flashing to improve recognition.
[0040] In this embodiment, the sensor includes a machine tool built-in sensor and / or an artificial external sensor.
[0041] In this embodiment, the acquisition module is used to acquire dynamic parameters of the machine tool pneumatic system, spindle lubrication system, guide rail lubrication system, and cooling system.
[0042] This embodiment of an interactive CNC machine tool maintenance method is used, taking the machine tool inspection and maintenance as an example: Pre-build interactive CNC machine tool maintenance system.
[0043] A machine tool maintenance database is established, including 3D models of the same structure as the on-site machine tools. The maintenance cycle, tools, spare part models, safety precautions, and maintenance completion standards for each machine tool component are then entered item by item according to the maintenance catalog. Based on the 3D model, action videos that match the maintenance catalog descriptions are then created as inspection and maintenance videos. Preset maintenance thresholds are also set, meaning that maintenance can begin when parameters reach the preset thresholds.
[0044] In order to accurately display the location of the parts that need maintenance, a virtual three-dimensional model with the same structure and size as the target machine tool equipment was produced, and the various components of the model can be rotated, enlarged, and reduced for viewing.
[0045] A connection is established with the machine tool's CNC system driver through a microservice application (API Server). Machine tool sensor data is obtained through a TCP request. The data is transmitted in a JSON data structure. On the computer side, the obtained JSON format data is parsed and extracted into an object 3D model. The object data is compared one by one with the preset maintenance threshold. If an item reaches the preset threshold, the maintenance priority of the item in the database is changed to the highest level, that is, it is displayed at the top of the sorting priority.
[0046] For example, a network cable is used to connect a computer to a CNC system port of a target machine tool in a workshop for communication, and the computer used is a desktop computer or a mobile computer terminal with input and output devices or functions.
[0047] Machine tool maintenance items can be sorted by data writing or using data management programs. Each maintenance item is divided into regular maintenance and irregular maintenance. Regular maintenance can be started as long as the specified maintenance time cycle is reached. This type of maintenance is sorted in ascending order according to the next maintenance time; irregular maintenance items can ignore the time and determine whether maintenance is required based on the machine tool sensor parameters; when regular maintenance and irregular maintenance items are sorted at the same time, irregular maintenance items are placed first.
[0048] The sorted maintenance items are displayed on the computer terminal interface in the form of clickable buttons. Items that require maintenance are highlighted in a warning color, items that have not reached their maintenance cycle are displayed in white or gray as normal, and items that have expired but have not been maintained are flashing as a warning. Considering that most operators use their right hand, the menu button is displayed on the right side of the computer monitor.
[0049] During maintenance, you can refer to the various operating steps in the machine tool's maintenance catalog to create corresponding maintenance actions for the 3D model. The parts that need maintenance are displayed in high brightness. During the animation playback, you can freely rotate and zoom the interface perspective, and you can also play and / or maintenance videos (maintenance videos are actual operation videos or simulation videos. In simulation videos, the corresponding parts are highlighted).
[0050] In addition, information related to maintenance tools, spare parts models, safety precautions, and maintenance completion standards are displayed on the left side of the display in different warning colors without blocking the viewing of the 3D model. After setting up the maintenance button, after clicking the button, the operator's identity will be authenticated and recorded using the employee number and password; An operation history query button is set to search the operation history and maintenance person information in the database and display them on the monitor.
[0051] If it is regular maintenance, there is no need to send an access request to the machine tool CNC system. The current maintenance time and maintenance person information can be directly entered into the database for the management department to use to trace the operation history records in the future. The maintenance catalog can be re-sorted and the completed maintenance items can be inserted into the bottom of the menu.
[0052] During regular maintenance intervals, the acquisition module collects dynamic parameters of components in real time; When a dynamic parameter triggers an alarm, maintenance is carried out, for example: The spindle lubricating oil is seriously depleted and the oil gauge issues an oil alarm; The display will automatically pop up a reminder button for insufficient spindle lubricating oil, and the button will automatically be displayed in the front and highlighted; Maintenance personnel can directly identify problems and then refuel. If they are not familiar with the refueling process, they can trigger the highlighted button to play the maintenance video and learn the operation. After replenishing the oil, just turn off the alarm and enter the operator information. The system will automatically record the alarm information and operator information.
[0053] If it is unscheduled maintenance, the machine tool CNC system is accessed through the microservice application to confirm that the sensor value has left the maintenance threshold, that is, the dynamic parameter and the preset threshold are qualified.
[0054] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
