Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular, to a data processing method, apparatus, device, and computer-readable storage medium. Background Art

[0002] With the diversification of market demands, laser scanning technology is also constantly innovating and developing. For uneven surfaces and irregular shapes, the traditional two-dimensional laser marking technology can no longer meet the market demands. In order to meet the requirements of curved surface processing, galvanometer-based three-dimensional laser scanning has gradually emerged with its characteristics such as high speed, high precision, small focused spot, and stable performance.

[0003] The dynamic focusing galvanometer is customarily called the Z-axis galvanometer, which is controlled by a voice coil motor and directly makes a reciprocating linear motion. The gap between the mover and the stator is very small, and sudden speed changes are likely to cause the motor to get stuck. This problem rarely occurs with the XY galvanometer that makes a rotational motion. This is a difficult problem in the voice coil motor industry. When marking a single object, data can be sorted, the marking path can be optimized, and the amplitude of Z-axis jumps can be reduced. Moreover, from the end point of one object to the starting point of another object, this problem cannot be avoided even with path optimization.

[0048] Those skilled in the art can understand that Figure 1 the terminal structure shown in

[0049] does not constitute a limitation on the terminal and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. Figure 1 As shown in

[0050] In Figure 1 the terminal shown, the network interface 1004 is mainly used to connect to the background server and communicate with the background server for data; the user interface 1003 is mainly used to connect to the client (user side) and communicate with the client for data; and the processor 1001 can be used to call the data processing program stored in the memory 1005.

[0051] In this embodiment, the data processing device includes: a memory 1005, a processor 1001, and a data processing program stored on the memory 1005 and operable on the processor 1001. When the processor 1001 calls the data processing program stored in the memory 1005, it executes the steps of the data processing method in each of the following embodiments.

[0052] The present invention also provides a data processing method. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of the method of the present invention.

[0053] In this embodiment, the data processing method includes the following steps:

[0054] Step S101, obtaining first spatial coordinate data of the starting point of the object to be marked and second spatial coordinate data of the first laser scanning point;

[0055] It should be noted that a set of galvanometer-type three-dimensional laser scanning processing systems includes a laser, a beam expander, XY two-axis reflecting galvanometers, a dynamic focusing lens group, and a galvanometer control unit. The laser is used to generate the laser for marking; the beam expander expands and collimates the laser beam and adjusts it into a parallel beam; the X-axis galvanometer and the Y-axis galvanometer are each connected to a servo motor and are used to deflect the laser beam emitted by the laser; the dynamic focusing lens group is used to control the change in the focal length of the laser beam passing through the beam expander, project it onto the X-axis galvanometer and the Y-axis galvanometer, and after two reflections by the two galvanometers, focus on the surface of the workpiece to form a scanning point. The galvanometer control unit obtains the contour point data of the graph to be scanned through the marking software and converts it into the driving data of the servo motor, thereby controlling the deflection of the galvanometer.

[0056] In this embodiment, first, the first spatial coordinate data of the starting point of the object to be marked is obtained. Here, the starting point refers to the point where the object to be marked starts marking first. Then, the first laser scanning point and the second spatial coordinate data of the first laser scanning point are obtained.

[0057] Step S102, determining third spatial coordinate data according to the first spatial coordinate data and the second spatial coordinate data;

[0058] In this embodiment, according to the obtained first spatial coordinate data and the second spatial coordinate data, the third spatial coordinate data is calculated. The first spatial coordinate data includes a first X-axis value, a first Y-axis value, and a second Z-axis value, and the second spatial coordinate data includes a second X-axis value, a second Y-axis value, and a first Z-axis value.

[0059] Further, step S102 includes:

[0060] Step S1021: Use the first X-axis value of the first spatial coordinate data, the second Y-axis value of the first spatial coordinate data, and the first Z-axis value in the second spatial coordinate data as the third spatial coordinate data.

[0061] In this embodiment, use the first X-axis value of the first spatial coordinate data, the second Y-axis value of the first spatial coordinate data, and the first Z-axis value in the second spatial coordinate data as the third spatial coordinate data. For example, if the first X-axis value of the first spatial coordinate data is 15, the second Y-axis value of the first spatial coordinate data is 16, and the first Z-axis value in the second spatial coordinate data is 19, then the X-axis value of the third spatial coordinate data is 15, the Y-axis value is 16, and the Z-axis value is 19.

[0062] Step S103: Control the first laser scanning point to move to the third spatial coordinate data to determine the second laser scanning point.

[0063] In this embodiment, control the X-axis galvanometer and the Y-axis galvanometer to deflect the laser beam, so that the first laser scanning point moves to the third spatial coordinate data at a preset maximum speed according to the third spatial coordinate data to determine the second laser scanning point.

[0064] Step S104: Determine the displacement from the third spatial coordinate data to the first spatial coordinate data according to the third spatial coordinate data and the first spatial coordinate data.

[0065] In this embodiment, determine the displacement from the third spatial coordinate data to the first spatial coordinate data according to the third spatial coordinate data and the first spatial coordinate data. The above displacement refers to the displacement between the two points determined by the third spatial coordinate data and the first spatial coordinate data.

[0066] Further, step S104 includes:

[0067] Step S1041: Perform a subtraction operation on the second Z-axis value in the first spatial coordinate data and the first Z-axis value to determine the difference.

[0068] Step S1042: Determine the displacement from the third spatial coordinate data to the first spatial coordinate data based on the absolute value of the difference.

[0069] In this embodiment, to calculate the displacement between the first spatial coordinate data and the third spatial coordinate data, only need to perform a subtraction operation on the second Z-axis value in the first spatial coordinate data and the first Z-axis value in the third spatial coordinate data to obtain the difference, and then take the absolute value operation of the difference to determine the displacement from the third spatial coordinate data to the first spatial coordinate data.

[0070] Step S105: Determine a third laser scanning point based on the second laser scanning point and the displacement.

[0071] In this embodiment, control the galvanometer in the Z-axis, adjust the focal length, and move the second laser scanning point in the direction of the displacement until the length of the displacement is completed, then determine the third laser scanning point.

[0072] Further, step S105 includes:

[0073] Step S1051: Divide the displacement into a first displacement, a second displacement, and a third displacement.

[0074] Step S1052: Determine the third laser scanning point based on the second laser scanning point, the first displacement, the second displacement, and the third displacement.

[0075] In this embodiment, first divide the displacement into a first displacement, a second displacement, and a third displacement. Specifically, the displacement can be trisected, and the length of each displacement segment is equal. For example, if the displacement size is 18, the sizes of the first displacement, the second displacement, and the third displacement can be 6, 6, and 6 respectively. Of course, the sizes of the first displacement, the second displacement, and the third displacement can also be set manually according to the specific mechanical requirements.

[0076] Then, control the second laser scanning point to move through the first displacement with uniformly accelerated motion, move through the second displacement with uniform linear motion, and move through the third displacement with uniformly decelerated linear motion to determine the third laser scanning point.

[0077] The data processing method proposed in this embodiment, by obtaining the first spatial coordinate data of the marking starting point and the second spatial coordinate data of the first laser scanning point, then determining the third spatial coordinate data based on the first spatial coordinate data and the second spatial coordinate data, then controlling the first laser scanning point to move to the third spatial coordinate data to determine the second laser scanning point, and then determining the displacement from the third spatial coordinate data to the first spatial coordinate data based on the third spatial coordinate data and the first spatial coordinate data, and finally determining the third laser scanning point based on the second laser scanning point and the displacement, can enable the second laser scanning point adjusted by the galvanometer in the Z-axis to accurately determine the third laser scanning point according to the displacement, thereby making the galvanometer in the Z-axis less likely to get stuck and improving the user experience.

[0078] Based on the first embodiment, a second embodiment of the data processing method of the present invention is proposed. In this embodiment, step S1052 includes:

[0079] Step S201: Determine a first acceleration according to the uniformly accelerated linear motion formula, the initial velocity of the second laser scanning point, the first displacement, and the preset maximum velocity.

[0080] Step S202: Control the second laser scanning point to perform a uniformly accelerated linear motion along the direction of the first displacement at the first acceleration until the first displacement is reached to determine the fourth laser scanning point.

[0081] Step S203: Determine the third laser scanning point according to the fourth laser scanning point, the second displacement, and the third displacement.

[0082] In this embodiment, the first acceleration can be simply calculated according to the uniformly accelerated linear motion formula, the initial velocity of the second laser scanning point, the displacement, and the preset maximum velocity. Then, the focal length of the second laser scanning point is controlled by the Z-axis galvanometer so that the second laser scanning point performs a uniformly accelerated linear motion along the direction of the first displacement at the first acceleration until the first displacement is completed, thereby obtaining the fourth laser scanning point. Finally, the third laser scanning point is determined according to the fourth laser scanning point, the second displacement, and the third displacement.

[0083] The data processing method proposed in this embodiment determines the first acceleration according to the uniformly accelerated linear motion formula, the initial velocity of the second laser scanning point, the first displacement, and the preset maximum velocity, then controls the second laser scanning point to perform a uniformly accelerated linear motion along the direction of the first displacement at the first acceleration until the first displacement is reached to determine the fourth laser scanning point, and finally determines the third laser scanning point according to the fourth laser scanning point, the second displacement, and the third displacement. This enables the second laser scanning point adjusted by the Z-axis galvanometer to determine the fourth laser scanning point according to the first acceleration, and further determines the third laser scanning point more stably, thereby making the Z-axis galvanometer less likely to get stuck and improving the user experience.

[0084] Based on the second embodiment, a third embodiment of the data processing method of the present invention is proposed. In this embodiment, step S203 includes:

[0085] Step S301: Control the fourth laser scanning point to perform a uniform linear motion along the direction of the second displacement at the preset maximum velocity until the second displacement is reached to determine the fifth laser scanning point.

[0086] Step S302: Determine the third laser scanning point according to the fifth laser scanning point and the third displacement.

[0087] In this embodiment, the Z-axis galvanometer controls the fourth laser scanning point to perform a uniform linear motion along the direction of the second displacement at the preset maximum velocity until the second displacement is completed to determine the fifth laser scanning point. For example, if the second displacement is 2 cm, the Z-axis galvanometer controls the fourth laser scanning point to perform a uniform linear motion at the preset maximum velocity of 20 cm per second. After 0.1 second, the displacement is 2 cm, and at this time, the second displacement is completed.

[0088] Finally, determine the third laser scanning point according to the fifth laser scanning point and the third displacement.

[0089] In the data processing method provided in this embodiment, by controlling the fourth laser scanning point to move in a uniform straight line along the direction of the second displacement at the preset maximum speed to the second displacement to determine the fifth laser scanning point, and then determining the third laser scanning point according to the fifth laser scanning point and the third displacement, it is possible to make the fourth laser scanning point adjusted by the Z-axis galvanometer determine the fifth laser scanning point according to the preset maximum speed, and then more stably determine the third laser scanning point, so that the Z-axis galvanometer is no longer easily stuck, improving the user experience.

[0090] Based on the above various embodiments, a fourth embodiment of the data processing method of the present invention is proposed. In this embodiment, step S302 includes:

[0091] Step S401, determine the second acceleration according to the uniformly decelerated linear motion formula, the third displacement, the preset end speed, and the preset maximum speed;

[0092] Step S402, control the fifth laser scanning point to move in a uniformly decelerated straight line along the direction of the third displacement at the second acceleration to the third displacement to determine the third laser scanning point.

[0093] In this embodiment, the second acceleration can be simply calculated according to the uniformly decelerated linear motion formula, the third displacement, the preset end speed, and the preset maximum speed. Among them, then, the preset end speed is the end speed of the fifth laser scanning point to complete the third displacement. By controlling the focal length of the scanning point by the Z-axis galvanometer, the fifth laser scanning point moves in a uniformly decelerated straight line along the direction of the displacement at the second acceleration until it finishes the third displacement, thereby obtaining the third laser scanning point.

[0094] In the data processing method provided in this embodiment, by determining the second acceleration according to the uniformly decelerated linear motion formula, the third displacement, the preset end speed, and the preset maximum speed, and then controlling the fifth laser scanning point to move in a uniformly decelerated straight line along the direction of the third displacement at the second acceleration to the third displacement to determine the third laser scanning point, it is possible to make the fifth laser scanning point adjusted by the Z-axis galvanometer more stably determine the third laser scanning point according to the second acceleration, so that the Z-axis galvanometer is no longer easily stuck, improving the user experience.
