Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a feeding position control method, system, terminal, and storage medium. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the holes continuously create very narrow kerfs (approximately 0.1 mm), completing the cutting process. In a laser cutting production line for pipes, a loading machine is needed to improve cutting efficiency. The pipe is hoisted onto the loading machine, which then delivers it to a V-shaped support via chain drive. The V-shaped support mechanism's movement and lifting are driven by a servo motor, which feeds the pipe into the cutting machine. The cutting machine then clamps the pipe with a chuck for further processing.

[0003] In actual production, it is necessary to align the feeding machine and the pipe cutting machine in the workshop. The specific alignment method is mostly to manually measure the distance between the feeding machine's outlet and the pipe cutting machine's inlet using testing instruments. During the measurement process, the PLC continuously adjusts the position of the feeding machine's outlet until it aligns with the pipe cutting machine's inlet. When measuring the distance between the feeding machine's outlet and the pipe cutting machine's inlet, it is necessary to find their characteristic points. Typically, the bottom of the feeding machine's V-shaped support mechanism is chosen as the characteristic point for the outlet.

[0004] However, after connecting the feeding machine and the pipe cutting machine, due to the center offset of the rectangular pipe in the V-shaped support mechanism, the chuck of the pipe cutting machine often fails to hold the rectangular pipe, requiring manual adjustment of the position of the rectangular pipe. Summary of the Invention

[0050] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] The feeding position control method provided in this embodiment of the invention is executed by a computer device, and correspondingly, the feeding position control system runs in the computer device.

[0053] Figure 1This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The executing entity can be a material loading position control system. Depending on different requirements, the order of steps in this flowchart can be changed, and some steps can be omitted.

[0054] like Figure 1 As shown, the method includes:

[0055] Step 110: Generate discharge reference coordinates based on the material receiving position of the pipe cutter;

[0056] Step 120: Obtain the pipe dimensions;

[0057] Step 130: Generate a deviation coefficient based on the pipe dimensions;

[0058] Step 140: Correct the reference coordinates based on the deviation coefficient to obtain the discharge coordinates.

[0059] To facilitate understanding of the present invention, the feeding position control method of the present invention will be further described below, based on the principle of the feeding position control method of the present invention and in conjunction with the process of controlling the feeding position in the embodiments.

[0060] Specifically, the feeding position control method includes:

[0061] S1. Generate discharge reference coordinates based on the material receiving position of the pipe cutting machine.

[0062] The position coordinates of the discharge reference point when aligned with the center of the pipe cutter chuck are saved as reference coordinates. The discharge reference point is the lowest point of the V-shaped support mechanism.

[0063] Specifically, a photoelectric switch can be used to test whether the discharge reference point of the feeder is aligned with the center of the pipe cutter's chuck. This involves installing two parts of the photoelectric switch at the discharge reference point of the feeder and the center of the pipe cutter's chuck. After adjusting the discharge reference point, when both are perfectly aligned, the PLC receives a signal from the photoelectric switch and saves the coordinates of the discharge reference point at that moment as reference coordinates.

[0064] S2. Obtain the pipe dimensions.

[0065] The specification information of the current pipe is retrieved from the PLC of the feeding machine, and the cross-sectional type of the pipe is analyzed based on the specification information. If the cross-section of the pipe is circular, the discharge reference coordinates are fixed as the discharge coordinates. If the cross-section of the pipe is rectangular, the length and width of the rectangle are extracted from the specification information.

[0066] If the PLC records the current pipe as a round pipe, no adjustment to the feeding position is needed; however, if it is a square pipe, the feeding position needs to be corrected. Extract the width *c* and length *d* of the rectangular cross-section of the square pipe. The cross-sectional position of the pipe on the V-shaped support mechanism is as follows: Figure 2 As shown.

[0067] S3. Generate a deviation coefficient based on the pipe dimensions.

[0068] Calculate the diagonal length L of the rectangle based on its length and width, where Extract the first angle α (typically 45°) between the first side of the V-shaped support mechanism and the horizontal plane from the PLC of the feeding machine; calculate the second angle b (b=arctan(c / d)) between the diagonal of the rectangle and the first side of the V-shaped support mechanism based on the length and width of the rectangle; calculate the horizontal deviation k1=L / 2* Vertical deviation k2 = L / 2 .

[0069] S4. Correct the reference coordinates based on the deviation coefficient to obtain the discharge coordinates.

[0070] For example, if the reference coordinates obtained in step S1 are (x, y), then the corrected discharge coordinates are (x+k1, y+k2). The PLC adjusts the lowest point of the V-shaped support mechanism of the feeder to the discharge coordinates, so that subsequent feeding can ensure that the rectangular tubes can be directly received by the pipe cutter.

[0071] In some embodiments, the loading position control system 300 may include multiple functional modules composed of computer program segments. The computer programs for each program segment in the loading position control system 300 may be stored in the memory of a computer device and executed by at least one processor to perform (see details).
