[0035] A protective spark viewing box 3 is installed on the X-direction accompanying track 2, and the upper and lower inner walls of the protective spark viewing box 3 are fixedly connected with mounting rods 51, and an image collector 5 is fixedly connected between the two mounting rods 51. The front and rear ends of the protective spark viewing box 3 are fixedly connected with spark viewing projection plates 31 that match the image collector 5, and the spark viewing projection plates 31 are located below the front side of the laser cutting head 15;

[0036] A laser cutting controller is also provided in the cutting platform 1, and a parameter self-adaptive control system is mounted in the laser cutting controller. The parameter self-adaptive control system includes a self-adaptive parameter processing unit, and the input end of the self-adaptive parameter processing unit is connected to a laser cutting parameter acquisition unit, a drive parameter acquisition unit and a spark imaging acquisition unit, and the output end of the self-adaptive parameter processing unit is connected to an X-direction accompanying control unit and a parameter compensation feedback unit;

[0037] The input ends of the laser cutting parameter acquisition unit and the drive parameter acquisition unit are both connected to the cutting control system signal set in the laser cutting controller, the input end of the spark imaging acquisition unit is connected to the image collector 5 signal, the output end of the X-axis accompanying control unit is connected to the X-axis accompanying track 2 signal, and the output end of the parameter compensation feedback unit is connected to the cutting control system signal set in the laser cutting controller. Through the cooperation of the protective spark viewing box 3, the image collector 5 and the parameter self-adaptive control system, when the cutting platform 1 performs laser cutting on medical metal parts, the spark state generated during cutting can be imaged and analyzed. The cutting state of the medical metal parts by the laser cutting head 15 is judged according to the spark state, and the rationality of the parameter settings of the cutting speed and laser power at this time is effectively judged, and the self-adaptive adjustment of the cutting speed and laser power parameters is produced. While meeting the cutting efficiency of the cutting platform 1 for medical metal parts, the cutting quality is effectively improved, and abnormal incision quality caused by unreasonable cutting speed and laser power is avoided, and the generation of heat-affected zones is reduced, which effectively reduces the thermal impact on medical metal parts during the laser cutting process, further ensures the cutting quality of medical metal parts, and effectively promotes the economic benefits of the cutting platform 1 processing.

[0038] It should be noted that the Y-axis drive structure 11, the X-axis drive structure 12, the slide 13, the Z-axis drive structure 14, and the laser cutting head 15 are all prior arts, which are the structures of the cutting platform 1 itself in the prior art. They are directly quoted here without any changes to their structures and principles, so they are not elaborated on. The X-axis accompanying rail 2 is prior art, which can adopt the structure of an electric slide rail, or a mechanical structure combination of a motor, a screw and a screw seat. Technical personnel in this field can select according to actual needs.

[0039] Figure 2 It is shown that the output end of the adaptive parameter processing unit is also connected to a spark abnormality alarm unit, and the output end of the spark abnormality alarm unit is connected to the alarm signal arranged on the cutting platform 1. The setting of the spark abnormality alarm unit can generate an alarm warning in time when the cutting spark abnormality exceeds the adjustable state, reminding the staff to check the cutting platform 1 and the medical metal parts to avoid the loss of raw materials and damage to the cutting platform 1 caused by continuous processing.

[0040] Figure 2It is shown that a temperature sensing probe is fixedly installed at the rear end of the protective spark viewing box 3, and the input end of the self-adaptive parameter processing unit is also connected to a laser heat dissipation collection unit. The input end of the laser heat dissipation collection unit is connected to the temperature sensing probe signal. The setting of the temperature sensing probe and the laser heat dissipation collection unit can collect data on the heat dissipation condition of the cutting platform 1 during the cutting process, and then collect data on the state of the heat affected zone during the cutting process. It can effectively ensure and control the data of the laser power, avoid damage to medical metal parts caused by excessive laser power, avoid excessive incisions, overburning or explosion holes, so as to ensure safety during the self-adaptive parameter regulation process.

[0041] Figure 2 The self-adaptive parameter processing unit is shown to include a data classification module, the input end of the data classification module is respectively connected to the laser cutting parameter acquisition unit, the drive parameter acquisition unit and the spark imaging acquisition unit, the output end of the data classification module is connected to the parameter control processing module and the spark image processing module, the output end of the parameter control processing module is connected to the execution data output module, the output end of the spark image processing module is connected to the image data output module, the output end of the execution data output module is connected to the X-direction accompanying control unit signal, and the output end of the image data output module is connected to the parameter compensation feedback unit signal. Through the setting of the parameter control processing module and the spark image processing module, the dual-channel processing function can be effectively realized. While improving the data processing efficiency, the data disorder of data control and image analysis can be effectively avoided, and the accuracy of the image processing data is effectively guaranteed. At the same time, the accompanying accuracy of the cutting path of the laser cutting head 15 is guaranteed, the accuracy of the spark image acquisition of the image collector 5 is improved, and the accuracy of subsequent image data processing and the reliability of subsequent self-adaptive parameter regulation are further guaranteed.

[0042] Figure 4 It is shown that a pair of vertical grooves 32 are provided on the side of the spark projection plate 31 close to the image collector 5, and the two vertical grooves 32 are respectively located on the left and right sides of the image collector 5. The setting of the vertical grooves 32 can assist the image collector 5 in collecting images and reduce the difficulty of image analysis by the spark image processing module. The vertical grooves 32 can be effectively used as a reference to improve the accuracy of spark state judgment.

[0043] Figure 2It is shown that a thickness sensor is fixedly connected to the lower end of the Z-axis driving structure 14, and a cutting thickness verification unit is also connected to the input end of the adaptive parameter processing unit. The input end of the cutting thickness verification unit is connected to the thickness sensor signal. The setting of the thickness sensor and the cutting thickness verification unit can further ensure the safety of the operation of the cutting platform 1, avoid the occurrence of errors in the cutting program setting or the wrong placement of the medical metal parts to be cut, and can provide a self-check protection for the cutting work of the cutting platform 1, thereby reducing the damage of the cutting platform 1.

[0044] Figure 2 It is shown that the output end of the self-adaptive parameter processing unit is also connected to the spark image database, and the input end of the spark image database is connected to the cloud server signal through the local area network. The input end of the self-adaptive parameter processing unit is also connected to the deep learning unit, and the input end of the deep learning unit is connected to the spark image database signal. The settings of the spark image database and the deep learning unit can further improve the intelligence of the cutting platform 1. The cutting platform 1 can not only store the spark data and parameter adjustment data generated during its own work, but also share and apply the spark data of other cutting platforms 1 in the application process through the cloud server, so as to continuously learn and improve the judgment of the spark image data, improve the judgment accuracy, and then improve the accuracy of regulating the cutting speed and laser power, and promote the cutting quality of medical metal parts.

[0045] It should be noted that the output end of the execution data output module is also connected to the spark abnormality alarm unit signal, the output end of the image data output module is connected to the spark image database signal, and the input end of the data classification module is also connected to the cutting thickness verification unit, the deep learning unit and the laser heat dissipation collection unit signal.

[0046] Figure 1 - Figure 8 It is shown that before the cutting platform 1 cuts the medical metal parts, the staff will input the material, thickness, size and other parameter data of the medical metal parts to be cut into the cutting control system, as well as the cutting route, cutting speed, cutting power, focal position and other related driving data. Then the cutting control system controls the Y-axis driving structure 11, the X-axis driving structure 12 and the Z-axis driving structure 14 according to the set data to drive the laser cutting head 15 to move. The laser cutting head 15 adjusts the focal position and installs the set cutting path and related data to perform laser cutting on the medical metal parts clamped on the upper end of the cutting platform 1.

[0047] Before the cutting control system controls the cutting platform 1 to produce work, it will also transmit the cutting related parameters to the laser cutting parameter acquisition unit in the parameter self-adaptive control system, and transmit the driving data to the driving parameter acquisition unit in the self-adaptive control system. The laser cutting parameter acquisition unit and the driving parameter acquisition unit will transmit the received data to the data classification module in the self-adaptive parameter processing unit. The data classification module classifies and processes the received data, and then transmits the cutting related parameters and driving data to the parameter control processing module, and transmits the cutting related parameters to the spark image processing module. The parameter control processing module sends a driving instruction to the execution data output module according to the driving instruction, so that the execution data output module The block X-direction accompanying control unit controls the X-direction accompanying track 2 to produce an effect. When the X-direction driving structure 12 drives the laser cutting head 15 to move in the X direction through the slide 13 and the Z-direction driving structure 14, the X-direction accompanying track 2 drives the protective spark viewing box 3 to move synchronously. Moreover, since the X-direction accompanying track 2 is fixedly connected to the crossbeam through the linkage plate 21, when the Y-direction driving structure 11 drives the laser cutting head 15 to move in the Y direction through the X-direction driving structure 12, the X-direction accompanying track 2 and the protective spark viewing box 3 will produce a synchronous movement effect, thereby maintaining the protective spark viewing box 3 continuously on the front side of the laser cutting head 15, and the image collector 5 can effectively collect data on the sparks generated by the cutting;

[0048] After the cutting control system drives the laser cutting head 15 to move the position of the medical metal part to be cut through the Y-axis driving structure 11 and the X-axis driving structure 12, the thickness measuring sensor collects the thickness data of the medical metal part at this time, and then transmits the collected thickness data to the data classification module in the self-applicable parameter processing unit. The data classification module transmits the thickness data to the parameter control processing unit. The parameter control processing unit compares the actual thickness data with the thickness data in the parameter. When the actual thickness data is within the parameter thickness data range, no data effect is generated. When the actual back-end data exceeds the parameter thickness data range, the abnormal data is transmitted to the spark abnormal alarm unit to activate the alarm and remind the staff to check the cutting program and the medical metal parts, so as to ensure the consistency of the cutting program and the medical metal parts data and ensure the safety of the cutting work.

[0049] When the cutting control system controls the laser cutting head 15 to perform laser cutting on medical metal parts, the image collector 5 can collect the spark data of the laser cutting head 15 cutting in the Y direction through the X-axis accompanying track 2 and the protective spark viewing box 3, and transmit the collected spark image data to the spark imaging acquisition unit, which transmits the data to the data classification module in the self-adaptive parameter processing unit, and the data classification module transmits the spark image to the spark image processing module, which processes the collected spark image data and the vertical groove 3. 2, and the deep learning unit will also learn through the spark state data in the spark image database, and then transmit the learning data to the spark image processing module through the data classification module, so that the spark image processing module can make a high-precision judgment on the collected spark image, and the temperature sensing probe will also collect the temperature of the lower side of the medical metal part, and then transmit it to the laser heat dissipation collection unit, the laser heat dissipation collection unit transmits the temperature data to the data classification module, and the data classification module transmits the temperature data to the spark image processing data, so that it can judge the spark state in combination with the temperature data;

[0050] When the spark state is judged to be a straight spark according to the spark image at this time, and the temperature is within the set range, it means that the laser power and cutting speed set by the program at this time are reasonably matched, and can ensure the cutting quality while ensuring the cutting speed. Therefore, the spark image processing module transmits the image data and analysis data to the image data output module at this time, and the image data output module transmits the data to the spark image database, and adds the spark data for the performance parameters of the cutting platform 1 in the spark image database. While increasing the data technology of the spark image database through the cloud server, the collection and storage of its own cutting data further promotes the learning effect of the deep learning unit, and continuously promotes the accuracy of the data analysis of the subsequent spark image processing module;

[0051] When the spark state is judged as spark diffusion according to the spark image at this time, it means that the laser power is too high or the cutting speed is too slow at this time, and then auxiliary judgment is made based on the temperature data. When the temperature is higher than the set range, it means that the heat affected zone of the cutting process is large at this time, indicating that the laser power is too high. The spark image processing module transmits the analysis result to the image data output module, and the image data output module transmits the analysis result to the parameter compensation feedback unit. The parameter compensation feedback unit transmits the compensation feedback of the excessive laser power to the cutting control system, so that the cutting control system adjusts the laser power to avoid the problem of excessively large incisions, overburning or explosion holes in medical metal parts due to excessive laser power, effectively ensuring that the cutting platform 1 is effective for medical The cutting quality and accuracy of metal parts, when the temperature is within the set range, it means that the cutting speed is too slow during the cutting process. The spark image processing module transmits the analysis result to the image data output module, and the image data output module transmits the analysis result to the parameter compensation feedback unit. The parameter compensation feedback unit transmits the compensation feedback of the slow cutting speed to the cutting control system, so that the cutting control system adjusts the cutting speed to avoid the situation where the incision is too large due to the slow cutting speed, thereby ensuring the cutting quality and accuracy of medical metal parts, and the image data output module transmits the image data and spark state data to the spark image database at the same time, and adds the spark data for the performance parameters of the cutting platform 1 in the spark image database;

[0052] When the spark state is judged as the spark becoming coarser and the temperature is higher than the set range according to the spark image at this time, it means that the laser power at this time exceeds the absorption capacity of the medical metal parts material, so it will cause the incision width to be too large and the heat affected zone to expand, and then the spark image processing module transmits the analysis result to the image data output module, the image data output module transmits the analysis result to the parameter compensation feedback unit, the parameter compensation feedback unit transmits the compensation feedback of the excessive laser power to the cutting control system, so that the cutting control system adjusts the laser power, and at the same time the image data output module transmits the image data and the spark state data to the spark image database at the same time, and adds the spark data for the performance parameters of the cutting platform 1 in the spark image database;

[0053] When the spark state is judged as spark reverse lag according to the spark image at this time, it means that the laser power is insufficient or the cutting speed is too fast. Then, auxiliary judgment is made based on the temperature data. When the temperature is lower than the set range, it means that the laser power is insufficient. The spark image processing module transmits the analysis result to the image data output module. The image data output module transmits the analysis result to the parameter compensation feedback unit. The parameter compensation feedback unit transmits the compensation feedback of insufficient laser power to the cutting control system, so that the cutting control system adjusts the laser power to avoid incomplete cutting due to excessive cutting speed. At the same time, the image data output module transmits the image data and spark state data to the spark image database at the same time to increase the number of spark images. The spark data for the performance parameters of the cutting platform 1 in the database, when the temperature is within the set range, indicates that the cutting speed is too fast at this time, the spark image processing module transmits the analysis result to the image data output module, the image data output module transmits the analysis result to the parameter compensation feedback unit, the parameter compensation feedback unit transmits the compensation feedback of the cutting speed being too fast to the cutting control system, so that the cutting control system adjusts the cutting speed to avoid the situation that the cutting is not thorough due to the cutting speed being too fast, so as to ensure the cutting quality and accuracy of the medical metal parts, and the image data output module transmits the image data and the spark state data to the spark image database at the same time, and adds the spark data for the performance parameters of the cutting platform 1 in the spark image database;

[0054] Therefore, during the continuous operation of the cutting platform 1, the cutting speed and laser power are adjusted adaptively according to the image analysis of the spark data and the temperature change data on the lower side of the medical metal parts to ensure the cutting efficiency and cutting quality, reduce the cutting scrap rate, and promote the economic benefits of the cutting platform 1 in processing medical metal parts.

The left end of the protective spark viewing box 3 is also fixedly connected to the protective cover 4. The upper end of the X-direction accompanying track 2 is provided with a track accompanying component 6 that matches the protective cover 4. The track accompanying component 6 includes a motor bracket 62 fixedly connected to the upper end of the X-direction accompanying track 2 and located on the inner side of the protective cover 4. The upper end of the motor bracket 62 is fixedly connected to a servo motor 61 located on the inner side of the protective cover 4. The lower end of the servo motor 61 is fixedly connected to a companion shaft 63. The lower end of the companion shaft 63 passes through the motor bracket 62 and is connected to the X-direction accompanying track 2. The track 2 is rotatably connected, and a plurality of linkage fins 64 are fixedly connected to the outer end of the accompanying shaft 63.

The setting of the protective cover 4 and the track accompanying component 6 can effectively realize the accompanying action of the cutting steering of the laser cutting head 15, and realize the full collection of the spark data generated on the cutting path of the laser cutting head 15 by the image collector 5, further improving the accuracy of the self-adaptive regulation of the cutting speed and the laser power, while ensuring the cutting efficiency, promoting the cutting quality of the cutting platform 1 for medical metal parts.

[0057] Fig.10 It is shown that the output end of the adaptive parameter processing unit is also connected to a trajectory accompanying steering unit, the output end of the trajectory accompanying steering unit is connected to the servo motor 61 signal, and the output end of the execution data output module is connected to the trajectory accompanying steering unit signal.

[0058] Figure 1 and Figure 4 - Figure 8It is shown that the parameter self-adaptive control system controls the X-direction accompanying control unit and the fixed connection mode of the linkage plate 21 and the X-direction driving structure 12 through the parameter control processing module and the execution data output module in the self-adaptive parameter processing unit, which can effectively realize the collection of Y-direction cutting sparks by the image collector 5. When the laser cutting head 15 performs X-direction cutting on medical metal parts, the parameter control processing module can send a steering drive instruction to the trajectory accompanying steering unit through the execution data output module, so that the trajectory accompanying steering unit controls the servo motor 61 to move, and the servo motor 61 drives the linkage fin plate 64 to rotate through the accompanying shaft 63, so that the linkage fin plate 64 drives the protective cover 4 and the protective spark viewing box 3 to rotate 90°, thereby making the protective spark viewing box 3 and the image collector 5 can generate spark data for the laser cutting head 15 during X-axis cutting, and can also realize the collection of spark images of the cutting path of the laser cutting head 15 in different directions according to the change of the rotation angle of the servo motor 61, effectively promoting the application scope of the image collector 5 and the parameter self-adaptive control system, and can be applied to the different cutting directions of the laser cutting head 15 for medical metal parts, and can effectively improve the all-round data collection and control of the laser power and cutting speed, further improve the intelligent control function of the cutting parameters, promote the accuracy of the self-adaptive control of the cutting speed and laser power, and promote the cutting quality of the cutting platform 1 for medical metal parts while ensuring the cutting efficiency, thereby improving the economic benefits of the cutting platform 1.
