Detailed Implementation
[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figure 1 - Figure 6 This invention provides a technical solution: an automatic stone setting device with three-dimensional recognition path teaching, including an automatic stone setting machine body 1. The automatic stone setting machine body 1 includes a diamond suction and release head 11, a linear driver 12, a diamond material tray 13, and a base 14. The diamond suction and release head 11 is installed at the output end of the linear driver 12, the linear driver 12 is installed on the top surface of the base 14, the diamond material tray 13 is installed on the top surface of the base 14, a fixing frame 2 is fixedly connected to one end of the linear driver 12, a three-dimensional scanning head 21 is installed at one end of the fixing frame 2, a workpiece support plate 32 is provided on one side of the base 14, a workpiece fixing seat 36 is fixedly connected to the top surface of the workpiece support plate 32, the three-dimensional scanning head 21 is located above the workpiece fixing seat 36, a support frame 3 is provided on one side of the base 14, a first servo motor 33 is installed at one end of the support frame 3, a lead screw 34 is rotatably connected inside the support frame 3, and one end of the lead screw 34 is connected to the output shaft end of the first servo motor 33. A fixed connection is made, and a movable plate 31 is movably connected to the top surface of the support frame 3. The bottom end of the movable plate 31 is threaded onto the outer wall of the lead screw 34. A support plate 35 is fixedly connected to the top surface of the movable plate 31. A second servo motor 37 is installed on the outer wall of the support plate 35. The other side of the support plate 35 is rotatably connected to one end of the workpiece support plate 32. A synchronous belt pulley assembly 38 is connected between the output shaft end of the second servo motor 37 and one end of the workpiece support plate 32. The diamond pick-up and drop-off head 11 is driven by the linear driver 12 to reciprocate between the diamond tray 13 and the workpiece fixed seat 36. The diamond pick-up and drop-off head 11 completes the diamond picking-up and dropping-out actions. The three-dimensional scanning head 21 performs a three-dimensional scan of the workpiece on the workpiece fixed seat 36. The second servo motor 37 drives the workpiece support plate 32 to rotate the workpiece. The full size data of the workpiece is collected, a three-dimensional model of the workpiece is established, and the processing path is generated by identifying the processing points on the workpiece.
[0032] A control method for an automated stone-laying device with three-dimensional path recognition teaching includes the following steps:
[0033] Step 1: Install and fix the workpiece on the workpiece fixing seat 36. Use the 3D scanning and recognition module to collect the workpiece size data through the 3D scanning head 21 to establish a 3D model of the workpiece. Generate the processing path by recognizing the processing points on the workpiece. By introducing the 3D scanning and recognition module, the teaching efficiency is greatly accelerated, replacing manual teaching.
[0034] In the process of generating the processing path, if the 3D model generated by 3D scanning is damaged and difficult to identify using 3D, the coordinates of the point to be processed can be obtained by filling the workpiece model with a virtual gemstone model.
[0035] Step 2: Obtain the assembly parameters of the automatic stone setting machine body 1 through the calibration module, and send motion mode instructions from the data layer. The control layer calls relevant control instructions according to the motion mode to complete the corresponding drill picking and placing motion actions and carry out stone setting processing.
[0036] Step 3: In the stone setting process, the sensor on the diamond suction head 11 is used to detect whether there is a diamond signal in the suction nozzle. Combined with the error detection module, the processing result is detected to determine whether there is a processing abnormality. The abnormality is sent to the data layer for analysis and processing and displayed in the presentation layer. The error detection module and calibration module are used for negative feedback adjustment to detect and calibrate the generated processing path, which increases the accuracy of automatically generating the path using 3D scanning.
[0037] Among them, the detection of whether there is a diamond signal in the suction nozzle. If the suction nozzle with a stone is already set still has a diamond signal, it is determined that the processing path generated by the 3D scanning and recognition module is incorrect, and then the parameter compensation is performed through the calibration module.
[0038] Step 4: Utilize the monitoring layer to monitor abnormal situations during processing, establish an abnormal situation analysis library, classify equipment abnormalities in different scenarios according to their severity, set different importance functions, and by establishing an abnormal situation analysis library and its importance functions, quickly handle abnormal situations and conduct follow-up inspections, thereby improving equipment stability and reducing maintenance costs.
[0039] When the monitoring layer detects an anomaly, the data layer performs the first follow-up processing according to the classification and accumulates the anomaly value. When the anomaly is triggered multiple times and the accumulated anomaly index reaches the set value, a second whole-machine inspection is performed.
[0040] Among them, the abnormal situation triggering mechanism is as follows: when the data layer receives abnormal situation data, it retrieves the abnormality level X and its importance function U from the abnormal situation analysis library. X (t), when the abnormal indicator Y exceeds the set value, the presentation layer prompts the user to perform a whole-machine inspection. The formula for calculating the abnormal indicator Y is as follows:
[0041]
[0042] Step 5: Quickly handle and track the occurrence of abnormal situations based on their frequency.
[0043] In this invention, diamond raw materials are stored in a diamond tray 13, and the workpiece is fixedly mounted on a workpiece holder 36. A linear actuator 12 drives a diamond pick-and-place head 11 to reciprocate between the diamond tray 13 and the workpiece holder 36, performing the actions of picking up and placing diamonds. A 3D scanning head 21 performs a 3D scan of the workpiece on the workpiece holder 36, and a second servo motor 37 drives the workpiece support plate 32 to rotate the workpiece, collecting comprehensive dimensional data of the workpiece and establishing a 3D model of the workpiece. A processing path is generated by identifying the points to be processed on the workpiece. During the stone setting process, the presence of a diamond signal is detected in the nozzle of the diamond pick-and-place head 11. The processing results are checked by an error detection module to determine if there are any processing abnormalities. The abnormalities are sent to the data layer for analysis and processing and displayed in the presentation layer. If a diamond signal is still present in the nozzle after stone setting, the 3D scanning and recognition module is deemed to be faulty. If the generated processing path is incorrect, parameter compensation is performed through the calibration module. Equipment anomalies occurring in different scenarios are classified according to severity, and different importance functions are set. When the monitoring layer detects an anomaly, the data layer performs the first follow-up processing according to the classification and accumulates the anomaly value. When the anomaly is triggered multiple times and the accumulated anomaly index reaches the set value, a second whole-machine inspection is performed. By introducing a 3D scanning and recognition module to collect workpiece size data, a 3D model of the workpiece is established. The processing path is generated by identifying the points to be processed on the workpiece, replacing manual teaching and greatly speeding up the teaching efficiency. The error detection module and calibration module perform negative feedback adjustment to detect and calibrate the generated processing path, increasing the accuracy of automatically generated paths using 3D scanning. By establishing an anomaly analysis library and its importance function, anomalies are quickly handled and tracked for inspection, improving equipment stability and reducing maintenance costs.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
