Description

Technical Field

[0001] The present disclosure relates to the technical field of standard part intelligence, and particularly to a coordinate system transformation method, device, equipment and medium for intelligent arrangement of standard parts. Background Art

[0002] With the continuous development of science and technology, the manufacturing industry is also constantly changing and upgrading. Among them, for intelligent die design, the intelligent arrangement of standard parts is an important criterion for measuring intelligent die design. The intelligent arrangement of standard parts refers to automatically identifying the body features corresponding to each standard part of the die and the standard part arrangement rules, and intelligently arranging the standard parts to the correct positions on the die.

[0003] Specifically, for the same type of standard parts, by using the intelligent arrangement algorithm of standard parts, the arrangement of standard parts is realized according to the posture of the standard parts and the position of the coordinate origin. However, since the postures and coordinate origin positions of the same type of standard parts designed by different standard part manufacturers may be different, it is impossible to use a unified intelligent arrangement algorithm to realize the intelligent arrangement of standard parts. Therefore, in order to be able to use a unified intelligent arrangement algorithm to realize the intelligent arrangement of standard parts, currently, the method of manual observation and calculation is adopted to achieve the unification of the same type of standard parts with different postures and coordinate origin positions. However, this method is very time-consuming, thus reducing the efficiency of arranging standard parts. Summary of the Invention

[0045] In order to more clearly understand the above-mentioned objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0047] Aiming at the problem in the prior art that due to the use of manual observation and calculation methods, it is very time-consuming to unify the same type of standard parts with different postures and coordinate origin positions, thus reducing the efficiency of the arrangement of standard parts.

[0048] Based on this, the present disclosure proposes a method for intelligent arrangement processing of standard parts. The coordinate system transformation method in the intelligent arrangement of standard parts can automatically determine the target point on the standard part to be transformed on the premise that the origin of the first coordinate system where the reference standard part is located, and determine the coordinate information of the target point in the second coordinate system where the standard part to be transformed is located. Further, in combination with the coordinate information of the target point and the second coordinate system, the target transformation parameters are calculated so that the origin of the target coordinate system coincides with the target point, and the directions of each axis are consistent with the direction of the reference standard part, realizing the coordinate unification of the standard part to be transformed and the reference standard part in the actual arrangement process automatically, without the need to manually observe and calculate the moving distance and rotation angle, simplifying the operation, thereby improving the efficiency of the arrangement of standard parts.

[0049] The coordinate system transformation method in the intelligent arrangement of standard parts provided by the present disclosure can be applied to a coordinate system transformation device in the intelligent arrangement of standard parts. The device can be various electronic devices such as personal computers, laptop computers, smart phones, tablet computers, and portable wearable devices. Optionally, the device can also be a functional module or functional entity in these electronic devices that can implement the coordinate system transformation method in the intelligent arrangement of standard parts.

[0050] The technical solutions of the present disclosure will be described below with several specific embodiments.

[0051] Figure 1 It is a flowchart of a coordinate system transformation method in the intelligent arrangement of standard parts provided by an embodiment of the present disclosure. As Figure 1 shown, the method of this embodiment includes the following steps:

[0052] S11. Obtain the first position of the reference origin on the reference standard part, and determine the target point on the standard part to be transformed based on the first position.

[0053] Among them, the reference origin is the origin of the first coordinate system where the reference standard part is located.

[0054] The reference standard part refers to the reference object for unifying the coordinate system where the standard part is located in the actual arrangement process, and the intelligent arrangement algorithm is set according to the coordinate system where the reference standard part is located. The reference standard part can be, for example, a pressure regulating pad, a guide plate, a positioning plate, etc., but is not limited thereto. The present disclosure does not specifically limit it, and those skilled in the art can set it according to the actual situation.

[0055] The standard part to be transformed refers to a workpiece with a similar structure, size, etc. to the reference standard part. However, due to different manufacturers of the same type of standard parts, the standard part to be transformed and the reference standard part may have different postures or coordinate systems. But it is not limited thereto. The present disclosure does not specifically limit it, and those skilled in the art can set it according to the actual situation.

[0056] Therefore, based on the above, for standard parts of the same type, in order to be able to arrange standard parts using an intelligent layout algorithm set according to the coordinate system where the reference standard part is located, it is necessary to unify the coordinate system where the standard part is located in the actual layout process based on the coordinate system where the reference standard part is located. However, this is not limited to this, and the present disclosure does not specifically limit it. Those skilled in the art can set it according to the actual situation.

[0057] The target point refers to the position of the origin of the coordinate system where the reference standard part is located on the reference standard part, and based on this, the point at the same position on the standard part to be transformed is determined.

[0058] Specifically, obtain the position of the origin of the first coordinate system where the reference standard part is located, thereby obtaining the first position of the reference origin on the reference standard part, and determine the position of the target point on the standard part to be transformed based on this first position.

[0059] Exemplarily, referring to Figures 2 - 3 As shown, for the reference standard part A, taking a vertex of the reference standard part A as the origin a, establish the first coordinate system X1, Y1, Z1. Then the reference origin is the origin a of the first coordinate system where the reference standard part A is located, and the position of the origin a is the first position a of the reference origin on the reference standard part. And based on this first position a, determine the target point a1 on the standard part B to be transformed. However, this is not limited to this, and the present disclosure does not specifically limit it. Those skilled in the art can set it according to the actual situation.

[0060] S12. Based on the second coordinate system where the standard part to be transformed is located, obtain the first coordinate information of the target point.

[0061] Specifically, determine the second coordinate system where the standard part to be transformed is located, and in this second coordinate system, determine the first coordinate information of the target point.

[0062] Exemplarily, referring to Figure 3 As shown, for the standard part B to be transformed, taking a point on the standard part B to be transformed as the origin b, establish the second coordinate system X2, Y2, Z2. Then based on this second coordinate system, obtain the first coordinate information of the target point a1 in this second coordinate system. For example, the coordinates of the target point a1 in this second coordinate system. However, this is not limited to this, and the present disclosure does not specifically limit it. Those skilled in the art can set it according to the actual situation.

[0063] Optionally, on the basis of the above embodiments, in some embodiments of the present disclosure, one implementation manner of S12 can be:

[0064] S121: Obtain the workpiece drawing of the standard part to be transformed.

[0065] Among them, the workpiece drawing refers to a drawing obtained by using drawing software such as Computer Aided Design (CAD) for the standard part to be transformed, but is not limited thereto. The present disclosure does not specifically limit it, and those skilled in the art can set it according to the actual situation.

[0066] S122: Based on the workpiece drawing, obtain the first coordinate information of the target point in the second coordinate system.

[0067] Specifically, obtain the workpiece drawing of the standard part to be transformed. After obtaining this workpiece drawing, in the second coordinate system corresponding to the standard part to be transformed, obtain the first coordinate information of the target point.

[0068] Exemplarily, the above-mentioned obtaining the first coordinate information of the target point in the second coordinate system based on the workpiece drawing can be, for example, by controlling a device such as a computer to import and obtain the workpiece drawing of the standard part to be transformed in the processing software, and determine the second coordinate system corresponding to the standard part to be transformed, so as to obtain the first coordinate information of the target point, but is not limited thereto. The present disclosure does not specifically limit it, and those skilled in the art can set it according to the actual situation.

[0069] Optionally, on the basis of the above embodiments, in some embodiments of the present disclosure, one implementation manner of S122 may be:

[0070] S1221: Determine the target point on the workpiece drawing, and establish a third coordinate system with the target point as the origin based on the first coordinate system.

[0071] Among them, the directions of the axes of the third coordinate system are the same as those of the axes of the first coordinate system.

[0072] S1222: In the second coordinate system, determine the first coordinate of the origin of the third coordinate system and the third unit vectors of the axes of the third coordinate system, so as to obtain the first coordinate information of the target point.

[0073] Exemplarily, referring to Figure 4 As shown, for the workpiece drawing B1 corresponding to the standard part B to be transformed, determine the position of the target point a1 on the workpiece drawing B1, and establish a third coordinate system X3, Y3, Z3 with the target point a1 as the origin b1. Among them, the horizontal axis X3 of the third coordinate system is in the same direction as the horizontal axis X1 of the first coordinate system, the vertical axis Y3 of the third coordinate system is in the same direction as the vertical axis Y1 of the first coordinate system, and the vertical axis Z3 of the third coordinate system is in the same direction as the vertical axis Z1 of the first coordinate system. That is, it can be understood that the third coordinate system X3, Y3, Z3 is the coordinate system corresponding to the first coordinate system X1, Y1, Z1 on the workpiece drawing B1 of the standard part to be transformed. Then, in the second coordinate system, obtain the first coordinate of the origin b1 of the third coordinate system as (Xb1, Yb1, Zb1), and obtain the third unit vectors of the axes of the third coordinate system such as The corresponding coordinates are (Xb1e, Yb1e, Zb1e), (Xb1f, Yb1f, Zb1f), (Xb1g, Yb1g, Zb1g), etc., from which the first coordinate information of the target point is obtained. However, this is not limited thereto, and the present disclosure does not specifically limit it, and those skilled in the art can set it according to actual situations.

[0074] S13. Determine the target transformation parameters of the second coordinate system based on the first coordinate information and the second coordinate information of the second coordinate system.

[0075] Among them, the target transformation parameters include: the target moving distance and the target rotation angle.

[0076] The above-mentioned target moving distance refers to the moving parameter for moving the origin of the second coordinate system where the standard part to be transformed is located to the target point, and the target rotation angle is the angle parameter that needs to be rotated to make the axes of the second coordinate system where the standard part to be transformed is located coincide with the axes of the third coordinate system established based on the first coordinate system.

[0077] S14. Obtain the target coordinate system based on the target point, the target transformation parameters, and the second coordinate system.

[0078] Among them, the target origin of the target coordinate system is in the same position as the target point in the reference standard part where the standard part to be transformed is located, the directions of the axes of the target coordinate system are the same as the directions of the axes of the first coordinate system, and the target coordinate system is used to arrange the standard part to be transformed.

[0079] Specifically, according to the obtained first coordinate information of the target point and the second coordinate information of the second coordinate system, calculate the target moving distance and the target rotation angle for moving and rotating the second coordinate system. According to the target point, the obtained target moving distance and the target rotation angle, move the second coordinate system, so as to obtain the target coordinate system, and use this target coordinate system to arrange the standard part to be transformed.

[0080] In the technical solution provided by the embodiments of the present disclosure, by obtaining the first position of the reference origin on the reference standard part, a target point is determined on the standard part to be transformed, where the reference origin is the origin of the first coordinate system where the reference standard part is located; based on the second coordinate system where the standard part to be transformed is located, the first coordinate information of the target point is obtained; based on the first coordinate information and the second coordinate information of the second coordinate system, the target transformation parameters of the second coordinate system are determined, where the target transformation parameters include: the target moving distance and the target rotation angle; based on the target point, the target transformation parameters, and the second coordinate system, a target coordinate system is obtained; where the position of the target origin of the target coordinate system on the standard part to be transformed is the same as the position of the target point on the reference standard part, the directions of the axes of the target coordinate system are the same as the directions of the axes of the first coordinate system, and the target coordinate system is used to arrange the standard part to be transformed. In this process, it is possible to automatically determine the target point on the standard part to be transformed on the premise of the origin of the first coordinate system where the reference standard part is located, and determine the coordinate information of the target point in the second coordinate system where the standard part to be transformed is located. Further, by combining the coordinate information of the target point and the second coordinate system, the target transformation parameters are calculated so that the origin of the target coordinate system coincides with the target point, and the directions of the axes are the same as those of the reference standard part, automatically realizing the coordinate unification of the standard part to be transformed and the reference standard part in the actual arrangement process, without the need to manually observe and calculate the moving distance and rotation angle, simplifying the operation, thereby improving the efficiency of arranging the standard parts.

[0081] Optionally, on the basis of the above embodiments, in some embodiments of the present disclosure, the second coordinate information includes: the second origin coordinate of the second coordinate system, and the second unit vectors of each axis. A possible implementation manner of S13 may be:

[0082] S131: Determine the target moving distance based on the first coordinate and the second origin coordinate.

[0083] Specifically, after determining the first coordinate of the origin of the third coordinate system, the target moving distance is determined according to the first coordinate and the second origin coordinate of the second coordinate system.

[0084] Exemplarily, continuing with the above embodiments, referring to Figure 4 as shown, for the first coordinate being (Xb1, Yb1, Zb1), in the second coordinate system X2, Y2, Z2, if the second origin coordinate of the second coordinate system is determined to be (0, 0, 0), then the difference is calculated between the first coordinate (Xb1, Yb1, Zb1) and the second origin coordinate (0, 0, 0) of the second coordinate system to calculate the target moving distance However, it is not limited thereto, and the present disclosure does not specifically limit it, and those skilled in the art can set it according to the actual situation.

[0085] S132: Determine the target rotation angle of each axis based on the third unit vectors of each axis of the third coordinate system and the second unit vectors of each axis of the second coordinate system.

[0087] S1321: Calculate the cross products respectively corresponding to the third unit vectors of each axis and the second unit vectors of each axis.

[0088] Exemplarily, continuing with the above embodiments, referring to Figure 4 as shown, for the third unit vectors of each axis of the third coordinate system such as the corresponding coordinates are (Xb1e, Yb1e, Zb1e), (Xb1f, Yb1f, Zb1f), (Xb1g, Yb1g, Zb1g), and for the second unit vectors of each axis of the second coordinate system such as the corresponding coordinates are (1, 0, 0), (0, 0, 1), (0, 1, 0), then according to the coordinates respectively corresponding to the third unit vectors of each axis of the third coordinate system such as and the coordinates respectively corresponding to the second unit vectors of each axis of the second coordinate system such as calculate the cross products corresponding to each axis.

[0089] S1322: Determine the target rotation angle of each axis based on the cross products respectively corresponding to each axis.

[0090] Specifically, after determining the third unit vectors of each axis of the third coordinate system in the second coordinate system, calculate the cross products respectively corresponding to the third unit vectors of each axis and the second unit vectors of each axis, and then determine the target rotation angle of each axis based on the cross products respectively corresponding to each axis.

[0091] It should be noted that when calculating the cross products respectively corresponding to each axis through the third unit vectors of each axis and the second unit vectors of each axis, first calculate the cross product corresponding to the horizontal axis Specifically, for the cross product corresponding to the horizontal axis it can be specifically defined according to the following expression:

[0092]

[0093] The target rotation angle for the horizontal axis can be specifically defined according to the following expression:

[0094]

[0095] After determining the cross product and the target rotation angle corresponding to the horizontal axis of the second coordinate system, rotate around the cross product Rotate the target by the rotation angle α to make the horizontal axis of the second coordinate system coincide with the horizontal axis of the third coordinate system. Since the direction of the horizontal axis of the third coordinate system is the same as that of the horizontal axis of the first coordinate system, the direction of the horizontal axis of the second coordinate system is also the same as that of the horizontal axis of the first coordinate system.

[0096] It should be noted that when and are in the same or opposite directions, the target rotation angle is determined to be 0 degrees or 180 degrees.

After rotating the vertical axis of the third coordinate system, determine the third unit vector of the vertical axis of the rotated third coordinate system. After determining the third unit vector of the vertical axis of the rotated third coordinate system, calculate the cross product of the vertical axis and the target rotation angle, and perform rotation to make the vertical axis of the second coordinate system coincide with the vertical axis of the third coordinate system, thereby obtaining the target coordinate system. For the calculation process of the cross product of the vertical axis and the target rotation angle, the third unit vector of the vertical axis of the rotated third coordinate system, and the cross product of the vertical axis and the target rotation angle, refer to the specific implementation process for the horizontal axis above, which will not be elaborated here.
