Description

Technical Field

[0001] The present disclosure relates to the technical field of curved surface diamond inlay, and in particular to a method and device for determining an optimization solution for a three-dimensional spot diamond inlay process. Background Art

[0002] Curved surface spot diamond inlay technology is a new process currently being applied in the field. Its accompanying feeding system enables a suction nozzle to pick up the material from a fixed point, extract the diamond through vacuum, and adjust the workpiece position using a dual-axis rotary table. When the suction nozzle moves to the spot diamond inlay processing point, the vacuum is broken to place and inlay the diamond, ensuring accurate placement and improving production efficiency.

[0003] Stereoscopic dot drilling machines are an implementation of dot-drilling technology for curved products. They are particularly widely used in the field of diamond-setting for curved jewelry, gradually replacing traditional manual diamond-setting techniques. For stereoscopic dot drilling machines, the following conditions must be met: first, the material removal point and the material feeding point must overlap in space; second, each feeder must only store one type of diamond; third, the optimal path must be found for processing points with different coordinates to avoid unnecessary travel by the dot-drilling head; and fourth, the feeder shaft must promptly respond to the diamond model information at each dot-drilling processing point. Before the dot-drilling head moves to the material removal point, the feeder equipped with that diamond model must be delivered to the point to avoid the dot-drilling head waiting for the feeder shaft to move.

[0004] The unit price of diamond inlay processing is relatively low in the market, and the industry relies heavily on processing volume to make profits. Therefore, in the actual production process, if the diamond inlay time is too long, it will lead to low efficiency and difficulty in maintaining labor costs. Shortening the process time can significantly improve the above shortcomings.

[0005] Currently, from the perspective of the relationship between feeding and spot drilling and inlay processing, the process for stereo spot drilling machines mainly involves determining the required motion target points of the feed shaft based on the processing sequence and executing the placement processing sequence planning based on the feeder sequence. The former process is the most commonly used. Because the feeder is transported by the feed shaft, the feed shaft's transport speed determines whether the feeding and processing can be effectively coordinated. In other words, the feed shaft's transport speed limits the improvement of processing efficiency.

[0006] Therefore, it is necessary to propose a technical solution that can further improve the processing efficiency of the three-dimensional point drilling machine and achieve optimization of the three-dimensional point drilling inlay process. Summary of the Invention

[0050] Figure 1 A flow chart of a method for determining a three-dimensional point diamond inlay process optimization solution provided by an embodiment of the present disclosure, referring to Figure 1 The present disclosure provides a method for determining an optimization solution for a three-dimensional point diamond inlay process, including but not limited to the following steps:

[0051] S110, obtaining processing point information of all point diamond inlays;

[0052] S120, determining a global optimal solution for the spot drilling and setting sequence and a motion target point sequence based on the genetic algorithm according to the processing point information, wherein the motion target point sequence represents a sequence in which the feeder corresponding to the spot drilling and setting processing point moves the feeder to the feeding fixed point;

[0053] S130, determining the spot drill inlay processing motion time according to the global optimal solution of the spot drill inlay sequence;

[0054] S140 , determining a spot drilling and setting process optimization solution according to the motion target point sequence and the spot drilling and setting processing motion time.

[0055] Optionally, in step S110, there are multiple processing points for spot diamond inlay.

[0056] Optionally, the processing point information for the point diamond setting can be obtained from the design data of the object to be set, and the design data includes the number and coordinates of the diamonds to be set.

[0057] Optionally, in step S120, the number and positions of the processing points are different, and there are many point drill inlay path solutions generated. The present disclosure uses a genetic algorithm to find the global optimal solution of the point drill inlay path and determine the global optimal point drill inlay processing sequence, which is the processing order of each processing point to be inlaid.

[0058] The three-dimensional spot drilling machine consists of a suction nozzle and a feeding system. The feeding system includes several feeders driven by a feed shaft. When a specific processing point needs to be spot drilled and set, the feed shaft moves the feeder to the corresponding feeding point. The suction nozzle then vacuums the diamonds from the feeder at this point. The object to be set is then fixed to a dual-axis rotary table. The dual-axis rotary table adjusts the workpiece's position. When the suction nozzle reaches the spot drill setting point, the vacuum is broken to place and set the diamond.

[0059] It can be seen from this that when the global optimal solution of the point drilling inlay path is determined, the processing order of the processing points is determined accordingly, the feeding fixed point sequence corresponding to each processing point is also determined accordingly, and the sequence in which the feeding axis moves the feeder to the feeding fixed point, that is, the motion target point sequence, is also determined.

[0060] Optionally, in step S130, the spot drill inlay processing movement time is the movement time of the suction nozzle from the material picking point to the processing point to the material removal point to return to the material picking point when the spot drill inlay processing point is processed.

[0061] Optionally, in step S140, based on the motion target point sequence and the spot drilling and inlaying processing motion time, the optimal operating speed of the feed shaft in cooperation with the suction nozzle to pick up materials can be adaptively derived, and the optimal operating speed of the feed shaft is sent to the motion control system of the suction nozzle and the feed shaft control system, so that it can be deduced at which time node the feed shaft should move the feeder to which feeding point.

[0062] It can be understood that the present invention optimizes the spot drill inlay path through genetic algorithms, saves the spot drill inlay movement stroke, and adaptively derives the optimal operating speed required by the feed shaft, so that the two processes of feeding and discharging can meet the requirements of concurrent and efficient connection, effectively improving the processing efficiency of the three-dimensional point drill machine and realizing the optimization of the three-dimensional point drill inlay process.

[0065] S220 , determining a spot drilling and setting process optimization solution according to the optimal operating speed of the feed shaft, wherein the spot drilling and setting process optimization solution includes a three-dimensional spot drilling machine driving the feed shaft according to the optimal operating speed of the feed shaft.

[0066] Figure 3 Provided for the embodiments of the present disclosure Figure 2 Flow chart of step S210; Figure 3 Optionally, determining the optimal operating speed of the feed shaft according to the motion target point sequence and the spot drilling and inlaying processing motion time includes:

[0067] S211, determining the displacement of the feeding shaft according to the coordinates of the current moving target point and the coordinates of the previous moving target point of the feeding shaft;

[0068] S212, determining the optimal running speed of the feed shaft according to the displacement of the feed shaft and the spot drilling and setting processing movement time.

[0069] Assume that the coordinates of the target point of the feeding axis are B n , that is, the displacement of the feeding shaft is:

[0070] S f =B n -B n-1 (n>1, and when n=1, S f =B1)

[0071] Thus we know

[0072] That is, when n=1,

[0073] When n>1,

[0074] Among them, V w is the point drilling and setting processing speed, S w It is the movement distance of the spot drill inlay processing.

[0075] It can be understood that the present disclosure provides a calculation scheme for the optimal operating speed of the feed shaft. After determining the optimal operating speed of the feed shaft, the optimal operating parameters of the feeder can be obtained, which can improve the processing efficiency of the stereo point drilling rig.

[0076] Figure 4 Provided for the embodiments of the present disclosure Figure 1 The flow chart of step S120 is shown in FIG. Figure 4 In any of the above technical solutions, further, the step of determining the global optimal solution of the point drilling sequence and the motion target point sequence based on the genetic algorithm according to the processing point information includes:

[0077] S410, obtaining an initial population of point diamond inlay sequence based on the processing point information and a random walk algorithm;

[0078] A random walk, also known as a random stroll, refers to an unpredictable progression and direction based on past performance. The core concept is that any random walker's conserved quantity corresponds to a diffusion transport law, akin to Brownian motion, representing its ideal mathematical state.

[0079] S420, determining a first fitness value of each individual in the initial population;

[0080] A coordinate system is established in the space where the 3D point drill machine is located, defining the X, Y, and Z axes. Each point drill inlay processing point on the 3D point drill machine has a different inlay height and workpiece rotation angle displacement stroke. Therefore, in addition to considering the path length on the XOY plane, the point drill inlay height and workpiece rotation angle must also be considered.

[0081] The XOY plane path length is calculated using the Chebyshev distance, which is calculated as follows:

[0082] L n =max(|X n -X n-1 |,|Y n -Y n-1 |)(n>1, and when n=1, L n =max(X1, Y1)); where (X n , Y n ) is the coordinate of the processing point on the XOY plane.

[0083] Remember Z n is the height coordinate of the drill bit inlay at the processing point. The placement height travel of the nozzle on the drill bit from the previous processing point to the current processing point is:

[0084] H n =Z n -Z n-1 (n>1, and when n=1, H n =Z1);

[0085] The angular coordinate of the first rotation axis of the workpiece is Rn , the angle coordinate of the second rotation axis of the workpiece is A n , the sum of the strokes of the two rotating axes is:

[0086] θ n =R n -R n-1 +A n -A n-1 (n>1, and when n=1, θ n =R1+A1).

[0087] The fitness function of each individual i is established as follows:

[0088]

[0089] According to F i Calculate the fitness value of each individual in the population.

[0090] S430, determining excellent individuals based on the first fitness value and generating a progeny population;

[0091] Using the roulette method, a random value Rand is generated, Rand∈(0,1), and the probability of each individual being inherited to the next generation is where m i is the individual with the desired probability, and the cumulative probability of each individual is Compare the relationship between the random value Rand and the cumulative probability. If Rand < Q[1], select individual 1. Otherwise, select individual k so that: Q[k-1] < Rand ≤ Q[k] holds, and select individuals M times in a cycle to select excellent individuals to enter the next generation and generate the offspring population.

[0092] S440, performing crossover and mutation operations on the individuals of the offspring population to determine a second fitness value of the mutated individuals; the second fitness value may also be calculated using a fitness function.

[0093] S450, after iterating the target number of times, determining the global optimal solution for the point diamond inlay sequence; the number of iterations can be set according to needs and experience, such as 50 times.

[0094] S460: Determine a moving target point sequence according to the global optimal solution of the point drilling and mosaicking sequence.

[0095] It can be understood that the present disclosure provides a technical solution for determining a global optimal solution based on a genetic algorithm, which will not limit further improvements in production speed and process efficiency.

[0096] Figure 5 Provided for the embodiments of the present disclosure Figure 1 Flow chart of step S130;

[0097] Reference Figure 5 In any of the above technical solutions, further, determining the spot drill inlay processing motion time according to the global optimal solution of the spot drill inlay sequence includes:

[0098] S510, determining a point drill inlay movement distance according to the global optimal solution of the point drill inlay sequence;

[0099] S520: Determine the spot drill inlay processing movement time according to the spot drill inlay movement distance.

[0100] The point drill inlay movement distance is calculated using the Chebyshev distance method. That is, the X-axis and Y-axis coordinate differences between the point drill inlay processing point and the material removal point are calculated respectively, and the maximum value of the two differences is taken as the point drill inlay movement distance. The point drill inlay movement distance is:

[0101] S w =max(|X place -X pick |,|Y place -Y pick |),

[0102] It is known that the target speed of XY axis is the set constant V w , we can see that the running time from taking material from the fixed point to drilling and inlaying processing and returning to the fixed point is

[0103]

[0104] Among them, T pp It is the movement time of the point diamond inlay processing.

[0105] In any of the above technical solutions, further, the processing point information includes the inlay height corresponding to the spot drill inlay processing point and the displacement stroke of the workpiece selection angle.

[0106] It can be understood that the present disclosure develops a fitness function based on the structure and process of the stereo point drilling rig and applies this fitness function to a genetic algorithm to obtain a global optimal solution for the point drilling and inlaying sequence. Furthermore, based on the global optimal solution for the point drilling and inlaying sequence, the order in which the feed shaft moves to the target feeding points is determined. A mathematical model for the single-processing operation time of the point drilling rig head retrieving material, spot drilling and inlaying, and returning to the retrieving position to prepare for the next placement is established using the global optimal solution for the point drilling and inlaying sequence. Based on the mathematical model for the single-processing operation time, a mathematical model for the speed at which the feed shaft moves to each target feeding point within this time is derived, and the optimal feed speed is calculated to achieve optimization of the point drilling and inlaying process. The present disclosure is used for optimizing the point drilling and inlaying process of a stereo point drilling rig.

[0107] The present invention formulates a fitness function according to the structure and process of the three-dimensional point drilling machine and applies this fitness function to the genetic algorithm, effectively reducing the risk of falling into a local optimal solution, obtaining a solution for the global optimal mounting sequence, thereby optimizing the point drilling inlay path, obtaining the order in which the feed shaft runs to the feeding target point according to the optimized point drilling inlay path, and adaptively calculating the optimal feeding speed of the feed shaft for each point drilling inlay processing point, thereby optimizing the mounting process.
