[0037] Embodiment one

[0038] Figure 1 A flow chart of a laser cutting graphic lead-in line positioning method is provided for the first embodiment of the present application. The present embodiment can be applicable to the case of laser cutting graphics. The method can be performed by the laser cutting graphic lead-in line positioning device provided by the embodiments of the present application. The device can be realized in the form of software and / or hardware, and can generally be integrated in a computer device. The method of the embodiments of the present application specifically includes:

[0039] S110: Obtain the starting point of the part graphic, and determine the perforation area according to the starting point.

[0040] Wherein, the part pattern refers to a pattern of a device to be laser cut, the starting point of the tool refers to a starting point of a laser cutting tool relative to the part to be cut, and the piercing area refers to an area where a piercing point is located. Before starting laser cutting, a position of the piercing point on the steel plate is selected first, and the piercing point refers to a small hole pierced on the plate before a complete contour cutting of the laser beam, so as to ensure that the laser energy enters the cutting seam.

[0041] Optionally, the starting point of the part pattern is acquired, including: acquiring part to be cut data, generating a cutting track according to the part to be cut data; and acquiring a starting position set by a user based on the cutting track, and taking the starting position as the starting point.

[0042] Specifically, the part pattern can be imported into a laser cutting numerical control system, so that the laser cutting numerical control system generates a corresponding cutting track according to the part to be cut data, or draws a cutting track of the part pattern in the laser cutting numerical control system. After the part pattern is imported, a default starting point is generated on the pattern by default, and the user can directly select the default starting point as the starting point, or manually select and determine the position of the starting point through the numerical control system.

[0043] Optionally, the piercing area is determined according to the starting point, including: determining a cutting-in type according to the starting point, wherein the cutting-in type includes internal cutting and external cutting; when the cutting-in type is internal cutting, the piercing area is determined to be inside the cutting track of the part pattern; and when the cutting-in type is external cutting, the piercing area is determined to be outside the cutting track of the part pattern.

[0044] Specifically, when the part pattern is internal cutting, the piercing point is generated inside the pattern, and when the pattern is external cutting, the piercing point is generated outside the pattern.

[0045] S120: acquiring an introduction line type, determining a piercing point according to the introduction line type, the starting point and the piercing area, and generating a final introduction line according to the starting point and the piercing point, wherein the introduction line type includes a straight line type, an arc line type and a shared type.

[0046] Specifically, after the starting point and the piercing point are set, an interface of the introduction line is popped up in the numerical control system, and the introduction line type is set in the interface, wherein the introduction line type includes three types: the straight line type, the arc line type and the shared type.

[0047] Optionally, the piercing point is determined according to the introduction line type, the starting point and the piercing area, and the final introduction line is generated according to the starting point and the piercing point, including: when the introduction line type is the straight line type, the piercing point is determined according to a straight line where the starting point is located and the piercing area; and a straight line segment from the starting point to the piercing point is taken as the final introduction line.

[0048] Specifically, the introduction line type is selected as a straight line type, and an angle between the starting point and the piercing point does not need to be set, and the generated introduction line is a straight line segment with the starting point and the piercing point as end points. This case is often used for cutting a straight edge starting point.

[0049] Optionally, the piercing point is determined according to the introduction line type, the starting point and the piercing area, and the final introduction line is generated according to the starting point and the piercing point, including: when the introduction line type is an arc line type, a first angle set by a user is obtained based on the starting point, and the piercing point is determined according to the first angle and the piercing area; and an arc line segment from the starting point to the piercing point is taken as the final introduction line.

[0050] Specifically, the introduction line type is selected as an arc line type, and a deflection angle at the starting point and the piercing point needs to be set. The setting method with the deflection angle can improve the flexibility of the arc line segment, and prevent slag generated during cutting from damaging the surrounding contour. This case is often used for cutting a circular arc starting point.

[0051] Optionally, the piercing point is determined according to the introduction line type, the starting point and the piercing area, and the final introduction line is generated according to the starting point and the piercing point, including: when the introduction line type is a shared type, a second angle set by a user is obtained based on the starting point, and the piercing point is positioned according to the second angle and the piercing area; an arc radius and an end point distance set by the user are obtained, and an arc length is calculated according to the arc radius and the end point distance; and the final introduction line is determined according to the arc length and the second angle.

[0052] Specifically, when the introduction line type is selected as the shared type, the piercing point is positioned in a straight line + arc line manner after the deflection angle at the starting point is set. The position of the starting point and the position of the piercing point form a straight line. The user can set the radius R of the arc line segment. The distance between the piercing point P1 and the starting point P0 is L, which is divided into three cases: 0.5L < R < L, L < R < 0.5L, and the length of the arc line segment in the corresponding case is calculated through a preset formula. The starting point P0 and the piercing point P1 do not change due to the deflection angle of the arc line segment. The starting point of the arc line segment is connected to the end point of the straight line segment. This case is often used for cutting an irregular circular arc edge starting point, and can avoid touching and damaging more positions of the plate.

[0053] S130: Positioning and cutting the part pattern according to the final introduction line.

[0054] Specifically, the part pattern is positioned and cut through the final introduction line, which can prevent the piercing point from being too close to the contour, and slag generated during cutting from affecting the cutting of the surrounding contour. The method is suitable for parts of various types and sizes, and has a wider application range. The path calculated through the method has better starting speed and starting angle, and can improve the processing efficiency and reduce the generation of NG waste materials.

[0055] The technical scheme of the embodiment of the present application determines the piercing area through the acquisition of the starting point of the part pattern, then determines the piercing point according to the acquired lead-in line type, the starting point and the piercing area, and generates the final lead-in line according to the starting point and the piercing point, and performs positioning cutting on the part pattern according to the final lead-in line. The position of the piercing point and the starting point is determined, the final lead-in line is further determined, the cutting efficiency is improved, the form and position of the lead-in line are freely adjusted according to the cutting habit of the user and the angle of the starting, the flexibility of the lead-in line is improved, the final lead-in line performs positioning cutting on the part pattern, and the distance between the piercing point and the contour is prevented from being too close, so that the slag generated during cutting does not affect the cutting of the surrounding contour.

[0066] S240: The part pattern is positioned and cut according to the updated lead-in line.

[0067] Specifically, after the lead-in point type is selected and the deflection angle is set to generate the final lead-in line, the user can continue to drag the starting point and the piercing point on the operation interface, and the position and shape of the lead-in line will change according to the set angle until it is judged that it does not affect other boundaries. The controller obtains the updated starting point and the updated piercing point moved by the user, updates the final lead-in line according to the updated starting point and the updated piercing point to generate an updated lead-in line, and then cuts and positions the part pattern according to the updated lead-in line.
