DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] Please refer to Figure 1 , Figure 1 The following is a flow chart of a CNC processing method for a mobile phone frame provided in an embodiment of the present application. The CNC processing method for a mobile phone frame in an embodiment of the present application can be applied to CNC processing equipment, such as Figure 2 As shown in the figure, CNC processing equipment includes processing tools, automated fixtures, manipulators, and material tables. Figure 1 As shown, the CNC processing method of the mobile phone frame of this embodiment includes steps S101 to S104, which are described in detail as follows: Step S101, controlling the robot to clamp the frame workpiece, and clamp the frame workpiece on the automated fixture of the dual-axis workbench.

[0018] In this step, a high-precision and high-efficiency automated assembly process is achieved through the coordinated work of the manipulator, automated fixture, and pressure sensor, ensuring the stability and safety of the frame workpiece during the assembly process.

[0019] In some embodiments, the step S101 includes: Controlling the manipulator to clamp the frame workpiece, and controlling the manipulator to move the automated fixture to a preset position, so as to drive the frame workpiece to move onto the automated fixture; Controlling the automated fixture to lock the frame workpiece, and collecting actual clamping force data of the frame workpiece through a pressure sensor on the automated fixture; If the actual clamping force data is not within the preset clamping force range, the clamping force of the automated clamp on the frame workpiece will be adjusted.

[0020] In this embodiment, the manipulator joints can be driven by the manipulator control, the position of the frame workpiece can be identified by combining with the visual sensor, and the motion trajectory of the manipulator can be calculated by using the path planning algorithm, or the manipulator can be accurately clamped and moved to the preset position of the automated fixture according to the preset motion trajectory. The automated fixture locks the frame workpiece pneumatically or electrically, and a pressure sensor is installed at the contact position between the fixture and the workpiece to monitor the clamping force in real time to ensure that the workpiece is subjected to appropriate pressure during the assembly process, thereby avoiding damage to the workpiece or poor assembly due to excessive or insufficient pressure.

[0021] Optionally, a clamping force range is preset. When the actual clamping force collected by the pressure sensor exceeds the range, the clamping force of the clamp is automatically adjusted through a PID control algorithm or other closed-loop control algorithm to keep it within the preset range, thereby improving the adaptive adjustment capability of the clamp and ensuring the accuracy and stability of the assembly process.

[0022] Step S102: processing the frame workpiece based on preset processing parameters, and monitoring the temperature data of the frame workpiece in real time.

[0023] In this step, the temperature sensor monitors the temperature changes in the processing process in real time, identifies abnormal conditions in time, and avoids deformation or damage of the workpiece due to overheating. The entire processing process realizes high-precision, high-efficiency and high-safety automated control to ensure the processing quality and production efficiency of the frame workpiece.

[0024] In some embodiments, the step S102 includes: Based on the processing specifications corresponding to the frame workpiece, selecting processing parameters corresponding to the frame workpiece, the processing parameters including tool specification parameters, tool working parameters, tool processing path and fixture moving path; Calling a machining tool with the tool specification parameters; According to the tool processing path and tool working parameters, control the processing tool to rotate and move in the Z-axis direction, and according to the fixture moving path, control the automated fixture to drive the frame workpiece to move in the X-axis direction and the Y-axis direction; During the processing of the frame workpiece, the temperature data of the real-time processing position of the frame workpiece is monitored based on a temperature sensor.

[0025] In this embodiment, based on the processing specifications of the frame workpiece and the corresponding processing parameters stored in the database, the optimal tool specification parameters, tool working parameters, tool processing path and fixture moving path are automatically selected to ensure the personalization and efficiency of the processing process. Automatically select and replace processing tools to reduce tool replacement time and improve production efficiency. Use numerical control (CNC) to accurately control the rotation speed and Z-axis motion trajectory of the processing tool, and use the servo motor to control the automatic fixture to drive the frame workpiece on the X-axis and Y-axis to ensure the accuracy of the tool and workpiece motion trajectory and improve processing accuracy and stability. By installing a temperature sensor on the processing equipment, the temperature changes of the workpiece and the tool during the processing process can be monitored in real time, and according to the temperature changes, the processing parameters or speed can be adaptively adjusted to ensure the stability and safety of the processing process, while avoiding workpiece damage and equipment failure caused by overheating.

[0026] Optionally, based on preset path generation constraints, a tool processing path and a fixture movement path corresponding to the border workpiece are generated, and the preset path generation constraints include that the processing time at any point of the border workpiece does not exceed the preset time. If the processing time at the first position exceeds the preset time, the next processing position is the second position, and the distance value between the first position and the second position is greater than the preset distance value.

[0027] In this optional embodiment, based on the preset path generation constraints, the tool processing path and fixture movement path corresponding to the frame workpiece are generated. These constraints include that the processing time at any location does not exceed the preset time to ensure processing efficiency and avoid friction overheating at any position. If the processing time of a first position exceeds the preset time, the next processing position is set to a second position farther away to ensure that the distance between the first position and the second position is greater than the preset distance value, thereby avoiding repeated heating and over-processing and maintaining the stability and precision of the workpiece. Through precise path planning and real-time adjustment, not only the processing speed and efficiency are improved, but also the quality of the frame workpiece during the processing is ensured, and the workpiece deformation and equipment wear caused by repeated heating and over-processing are reduced.

[0028] Step S103, if the temperature data is greater than a preset temperature value, the preset processing parameters are optimized to keep the temperature data not greater than the preset temperature value until the frame workpiece is processed and a frame product is obtained.

[0029] In this step, the frame products obtained by CNC processing are as follows Figure 3 As shown. By real-time monitoring of temperature data during processing, when the temperature exceeds the preset value, the preset processing parameters are automatically adjusted according to the preset optimization strategy, such as adjusting the processing path, reducing the processing speed, adjusting the coolant flow, etc., to generate the first optimization parameters. Use these optimization parameters to continue processing and continue to monitor the temperature. If the temperature is still too high, adjust the optimization parameters again, generate the second optimization parameters, and continue processing and monitoring. Through the iterative optimization process, ensure that the temperature is always within a safe range until the frame workpiece is processed, avoid workpiece damage and equipment failure due to overheating, and improve production efficiency and product quality.

[0030] In some embodiments, the step S103 includes: If the temperature data is greater than a preset temperature value, the preset processing parameters are optimized based on a preset optimization strategy to obtain first processing optimization parameters; Based on the first processing optimization parameter, the frame workpiece is processed, and the temperature data of the frame workpiece is continuously monitored; If the temperature data that continues to be monitored is greater than the preset temperature value, the first processing optimization parameter is optimized based on the preset optimization strategy to obtain the second processing optimization parameter; Based on the second processing optimization parameter, the frame workpiece is processed, and the temperature data of the frame workpiece is continuously monitored to keep the temperature data not greater than a preset temperature value until the processing of the frame workpiece is completed to obtain a frame product.

[0031] In this embodiment, the temperature data of the processing process is monitored in real time by a temperature sensor. If the temperature is detected to exceed the preset temperature value, it means that the processing process reaches the deformation threshold of the workpiece material, and the optimization strategy is immediately started to adjust the preset processing parameters to generate the first processing optimization parameters, such as adjusting the processing path, reducing the processing speed, adjusting the coolant flow, etc., to control the temperature rise. Use these optimization parameters to continue processing while continuously monitoring the temperature data. If the temperature exceeds the preset temperature value again, the optimization strategy is started again, the first processing optimization parameters are further adjusted, and the second processing optimization parameters are generated, and processing and monitoring are continued. Through dynamic adjustment, it is ensured that the temperature is always within a safe range until the frame workpiece processing is completed. This embodiment not only improves the stability and safety of the processing process, but also avoids workpiece damage and equipment failure caused by overheating, thereby significantly improving production efficiency and product quality.

[0032] Optionally, the optimization process of the processing optimization parameters includes: Based on the preset processing parameters, determining a target processing position in a subsequent processing position that is greater than a preset distance value from the current processing position; The next processing position is changed to the target processing position, and based on the target processing position, the preset processing parameters are updated to obtain the first processing optimization parameters.

[0033] In this optional embodiment, the target processing parameters corresponding to the target processing position are changed to the starting processing parameters of the next time sequence in the preset processing parameters, and the target processing parameters of the original time sequence in the preset processing parameters are deleted to obtain optimized parameters; based on a preset verification strategy, the optimized parameters are verified; if the verification passes, the processing optimization parameters are determined as the first processing optimization parameters.

[0034] The processing quality and efficiency of the frame workpiece can be significantly improved through processing position adjustment and optimization verification. Based on the preset processing parameters and the current processing position, the target processing position with a distance greater than the preset value from the current processing position in the subsequent processing position is automatically determined, and the next processing position is changed to the target processing position to avoid heat accumulation and mechanical loss caused by frequent position switching of the tool during the processing process. At the same time, the target processing parameters corresponding to the target processing position are adjusted to the starting processing parameters of the next sequence in the preset processing parameters to ensure the consistency and optimization of the parameters during the processing. To further optimize the processing parameters, the target processing parameters of the original sequence in the preset processing parameters will be deleted to generate new optimized parameters.

[0035] On this basis, the newly generated optimization parameters can also be verified based on the preset verification strategy. The verification strategy can include multiple aspects such as the rationality of the parameters, the convergence of the processing path, and the adaptability of the parameters. If the verification passes, these optimization parameters are used as the first processing optimization parameters; if the verification fails, return to the steps of reselecting the processing position and adjusting the processing parameters until the optimization parameters pass all necessary verifications. In the above manner, the adaptability and accuracy of the parameters in the processing of the frame workpiece are significantly improved, and frequent parameter adjustments and unnecessary mechanical wear are reduced. At the same time, through real-time monitoring and automatic adjustment, the efficiency and stability of the entire processing process are ensured, thereby improving production efficiency and product quality.

[0036] Step S104, controlling the robot to remove the frame product from the automated fixture.

[0037] In this step, the position and state of the frame product and the state of the automated fixture can be accurately determined based on computer vision and motion control algorithms; the robot can also be controlled through preset path planning and action sequences to accurately remove the frame product from the automated fixture while ensuring that the contact position is stable and the product is not damaged. This embodiment not only reduces the labor intensity and human errors of manual operation, but also improves the speed and accuracy of the pick-and-place operation. Since the robot can quickly and accurately perform preset actions, it can effectively reduce the waiting time for product pick-and-place on the production line, greatly improving production efficiency.
