Description

Technical Field

[0001] The invention relates to the technical field of tube laser cutting, and in particular to a dual-axis synchronous laser cutting machine suitable for plastic tube processing and a control system thereof. Background Art

[0002] The traditional pipe cutting method is to use a motor to drive the cutting saw blade to rotate at high speed to cut the pipe. Compared with the traditional pipe cutting method, laser cutting has less thermal impact and precise cutting. It can be cut into shape in one time, accurately and without burrs.

[0003] A tube laser cutting device is disclosed in the publication number CN217942242U. The device cooperates with a conveyor belt and an intercepting member. The intercepting member is used to cut the tube clamped on two conveyor belts while driving the tube to rotate. After the cutting is completed, the intercepting member is adjusted to the release position. In this way, there is no need to clamp the tube and drive the clamping fixture to rotate. However, when cutting both ends of the tube, the above patent needs to disassemble one end of the cut tube and reinstall it before continuing to cut the other end of the tube, which greatly affects the cutting efficiency of the tube. At the same time, it is impossible to identify and locate the cutting work according to the placement position of the tube.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

The automated processing efficiency of the equipment is further improved by data acquisition and analysis. Image data analysis at both ends of the plastic pipe helps to achieve automatic identification, positioning and cutting of both ends of the plastic pipe. By calibrating, tracking and supervising the cutting data, it is possible to understand whether the cutting trajectory meets the standards during the cutting process of the plastic pipe, so as to carry out reasonable and targeted management according to the information feedback, so as to improve the cutting accuracy of the equipment, which helps to improve the cutting quality of the plastic pipe and solve the above-mentioned technical defects.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] If the offset cut value is less than the preset offset cut value threshold, no signal is generated;

[0058] If the offset cutting value is greater than or equal to the preset offset cutting value threshold, an alarm signal is generated and sent to the execution management unit. After receiving the alarm signal, the execution management unit immediately performs the preset warning operation corresponding to the alarm signal so as to adjust the equipment in time to ensure the cutting accuracy of the equipment.

When the positioning self-checking unit receives the processing instruction, it immediately collects the displacement data of the plastic pipe, and adjusts the displacement data for self-checking processing to obtain a start signal and an adjustment signal. After the execution management unit responds to the adjustment signal, it immediately controls the drive motor 7 to work;

[0061] The image analysis unit responds to the start signal, collects image data of both ends of the plastic pipe, and performs identification and positioning processing on the image data to obtain a first cutting point and a second cutting point;

[0063] To sum up, the precise cutting of plastic pipes is completed by mechanical and system linkage, which helps to improve the cutting efficiency of plastic pipes. That is, the flip wheel 12 is mechanically driven to drive the plastic pipe to rotate to achieve overall cutting, and the cutting at both ends is achieved by movement to avoid repeated installation, which helps to shorten the processing time. At the same time, the mobile limit method is used to facilitate the rapid installation of plastic pipes, and the automated processing efficiency of the equipment is further improved by data collection and analysis. Image data analysis at both ends of the plastic pipe helps to achieve automatic identification, positioning and cutting of both ends of the plastic pipe, calibrate, track and supervise the cutting data, and understand whether the cutting trajectory meets the standards during the plastic pipe cutting process, so as to carry out reasonable and targeted management according to the information feedback, so as to improve the cutting accuracy of the equipment, and thus help to improve the cutting quality of the plastic pipe.

[0064] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value. The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered within the protection scope of the present invention.
