[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] Figure 1This is a schematic diagram of a method for correcting workpiece fixed points provided by the present application. Figure 1 As shown, including:

[0048] S101, obtaining the fixed-point coordinates of the workpiece, a first margin value, a second margin value, and the origin of the workpiece pallet, wherein the first margin value is the straight-line distance between the edge of the workpiece and the edge of the workpiece pallet in the first direction, and the second margin value is the straight-line distance between the edge of the workpiece and the edge of the workpiece pallet in the second direction, and the first direction and the second direction are perpendicular to a horizontal plane parallel to the workpiece pallet;

[0049] S102, determining the initial fixed point coordinates of the workpiece on the workpiece pallet according to the preset size value of the workpiece, the first margin value and the second margin value, wherein the preset size value of the workpiece includes: the length of the workpiece in the first direction, the second direction and the third direction, wherein the third direction is perpendicular to the surface of the workpiece pallet;

[0050] S103, determining the corrected fixed-point coordinates of the workpiece according to the origin of the workpiece pallet, the fixed-point coordinates of the workpiece and a preset error value.

[0051] It should be noted that fixed point means that during the processing, the workpiece is accurately placed or fixed at a preset position through fixtures, positioning devices or other means. The preset position is determined in advance based on factors such as processing technology requirements, workpiece size and shape, to ensure processing accuracy and consistency.

[0052] Furthermore, the fixed-point coordinate of the workpiece may be the center point of the workpiece, and the origin of the workpiece pallet may be any point, which is not limited here.

[0053] like Figure 2 As shown, for example, it is assumed that the fixed-point coordinate of the workpiece is the center point, the lower left corner of the workpiece pallet is the origin, d1 to the right of the origin is the first direction, d2 perpendicular to d1 is the second direction, d3 perpendicular to the origin is the third direction, the workpiece is 10 cm long, 6 cm wide, and 2 cm high, the preset error value is 0.1 cm, the first margin at this time is 12 cm, and the second margin is 16 cm. According to the center point of the workpiece and the length of the workpiece, the coordinates of the center point of the workpiece in the direction of d1 are 17, the coordinates of the center point of the workpiece in the direction of d2 are 19, and the coordinates of the center point of the workpiece in the direction of d3 are 2. The initial fixed-point coordinates of the workpiece are (17, 19, 2). The initial fixed-point coordinates of the workpiece are corrected according to the preset error value. For example, the preset error value is +0.1, and the corrected fixed-point coordinates are (17.1, 19.1, 2.1).

[0054] The present application calculates the initial fixed-point coordinates according to the fixed-point coordinates of the workpiece, the first margin value and the second margin value, and performs correction accordingly, which has the significant advantages of improving processing accuracy, reducing human errors and enhancing processing flexibility.

[0055] In an embodiment that can be implemented in the present application, the method further includes: aligning a fourth direction preset for the workpiece with the first direction, and aligning a fifth direction preset for the workpiece with the second direction, so that the workpiece reaches a preset angle on the workpiece pallet. The fourth direction corresponds to the direction of the first margin value, and the fifth direction corresponds to the direction of the second margin value.

[0056] The present application ensures that the workpiece maintains a stable posture and position during the processing by accurately aligning the direction of the workpiece, thereby reducing the processing error caused by the position deviation of the workpiece and improving the processing accuracy and product quality.

[0057] In one embodiment that can be implemented in this application, Figure 3 It is a flowchart of an embodiment provided by the present application.

[0058] Determining the initial center value coordinates of the workpiece on the workpiece pallet according to the fixed point coordinates, the size value, the first margin value and the second margin value of the workpiece includes:

[0059] S301, determining a third margin value, a fourth margin value and a height value of the workpiece according to the size value of the workpiece and the fixed point coordinates of the workpiece, wherein the third margin value is a straight-line distance value between the edge of the workpiece and the fixed point of the workpiece in the first direction, the fourth margin value is a straight-line distance value between the edge of the workpiece and the fixed point of the workpiece in the second direction, and the height value is a straight-line distance value between the highest point of the workpiece in the third direction and the surface of the workpiece pallet;

[0060] S302, determining the initial fixed point coordinates of the workpiece on the workpiece pallet according to the first margin value, the second margin value, the third margin value, the fourth margin value and the height value.

[0061] This application significantly improves the efficiency of workpiece placement and subsequent processing on the pallet through automated measurement, calculation and positioning.

[0062] In an embodiment that can be implemented in this application, Figure 4 It is a flowchart of an embodiment provided by the present application.

[0063] Determining the initial fixed point coordinates of the workpiece on the workpiece pallet according to the first margin value, the second margin value, the third margin value, the fourth margin value and the height value includes:

[0064] S401, determining a coordinate value of the workpiece in a first direction on the workpiece pallet according to the first margin value and the third margin value;

[0065] S402, determining a coordinate value of the workpiece in a second direction on the workpiece pallet according to the second margin value and the fourth margin value;

[0066] S403: Determine the coordinate value of the workpiece in the third direction on the workpiece pallet according to the height value.

[0067] For example, Figure 2 As shown, the third margin and the fourth margin of the workpiece are calculated. Assuming that the workpiece is 10 cm long, 6 cm wide, and 2 cm high, the center point of the workpiece is the fixed point. The distance from the center point of the workpiece to the edge of the workpiece in the first direction is 5 cm, that is, the third margin is 5 cm, and the distance from the center point of the workpiece to the edge of the workpiece in the second direction is 3 cm, that is, the fourth margin is 3 cm. If the first margin is 8 cm and the second margin is 10 cm, the initial fixed point coordinates are obtained according to the first margin, the second margin, the third margin, the fourth margin and the height of the workpiece as (13, 13, 2).

[0068] In an embodiment that can be implemented in the present application, determining the coordinate value of the workpiece in the first direction on the workpiece pallet according to the first margin value and the third margin value includes:

[0069] The first margin value and the third margin value are added to determine the coordinate value of the workpiece in a first direction on the workpiece pallet.

[0070] The present application calculates the initial fixed-point coordinates of the workpiece by measuring the first margin, the second margin, the third margin and the fourth margin, realizes automation when determining the fixed-point coordinates, and improves the efficiency of determining the fixed-point coordinates.

[0071] In an embodiment that can be implemented in this application, Figure 5 The method of determining the corrected workpiece fixed-point coordinates according to the origin of the workpiece pallet, the fixed-point coordinates of the workpiece and the preset error rate includes:

[0072] S501, determining the fixed-point coordinates of the machine tool according to the origin of the workpiece pallet and the fixed-point coordinates of the workpiece;

[0073] S502, determining the corrected workpiece fixed-point coordinates according to the machine tool fixed-point coordinates and a preset error rate.

[0074] In an embodiment that can be implemented in this application, Figure 6 It is a flowchart of an embodiment provided by the present application.

[0075] Determining the fixed-point coordinates of the machine tool according to the origin of the workpiece pallet and the fixed-point coordinates of the workpiece includes:

[0076] S601, subtracting the coordinate value of the initial fixed point in the first direction from the coordinate value of the workpiece pallet origin in the first direction to determine the coordinate value of the machine tool fixed point in the first direction;

[0077] S602, adding the coordinate value of the second direction of the origin of the workpiece pallet to the coordinate value of the second direction of the initial fixed point to determine the coordinate value of the second direction of the machine tool fixed point;

[0078] S603, assigning the third direction coordinate value of the fixed point of the workpiece to the third direction coordinate value of the fixed point of the machine tool.

[0079] This application converts the fixed-point coordinates of the workpiece into the fixed-point coordinates of the workpiece on the machine tool through this step, laying the foundation for subsequent precise processing.

[0080] For example, Figure 7 As shown, the lower right corner of the workpiece pallet is set as the origin (0, 0, 0). Suppose the detected size of the workpiece is 14 cm in length in the direction of d1, 8 cm in width in the direction of d2, and 3 cm in height on d3. According to the size of the workpiece, x1 is calculated to be 7 cm, y1 is 4 cm, and x2 is measured to be 2 cm, y2 is 8 cm. The coordinates of the initial fixed point of the workpiece calculated according to x1, x2, y1 and y2 are (9, 12, 3). The fixed point coordinates of the workpiece on the machine tool calculated according to the initial fixed point coordinates and the origin coordinates are (-9, 12, 3).
