Description

Technical Field

[0001] The invention relates to the technical field of full-automatic feeding, and in particular to an automatic feeding device for a laser tube cutting machine. Background Art

[0002] Laser tube cutting machine is an industrial equipment that uses laser to process tubes. When working, the laser tube cutting machine uses a high-power, high-density laser beam to irradiate the tube to be cut, so that the tube is quickly heated to the vaporization temperature, evaporates to form holes, and then rotates the tube to move the beam relative to the tube, and then the holes continuously form a very narrow (such as about 0.1mm) slit, thereby completing the cutting of the tube. Laser tube cutting machine has the characteristics of good cutting quality, fast speed, high cutting efficiency, and no consumables, so it is widely used.

[0003] At present, laser tube cutting machines can perform batch processing, and rapid loading is required during processing to supply the tube cutting machines. However, the existing manual or semi-automatic loading methods are relatively inefficient and cannot operate continuously, which not only seriously affects the processing efficiency and reduces the use efficiency of the equipment, but also during the processing, if the tubes in the same batch are of different lengths, it is often difficult to load them.

[0004] Therefore, it is necessary to study a fully automatic feeding device to achieve efficient and automatic feeding of the laser tube cutting machine.

[0184] like Fig.18 As shown, the overall workflow and working method of the embodiment of the present invention are as follows:

[0185] S100: placing the pipe from the storage frame to the induction conductive plate of the conveying beam;

[0186] S200: Detect whether there is a pipe at the induction conductive plate. If there is a pipe, proceed to S300; if not, return to S100;

[0187] S300: Use the fork plate to withdraw the pipe, leaving only one pipe at the induction conductive plate;

[0188] S400: Use the fork plate to push the pipe to the induction baffle;

[0189] S500: Use the length measuring assembly to measure the length of the pipe;

[0190] S600: According to the measured length of the pipe, adjust the position of the movable sliding assembly so that it can clamp the pipe normally;

[0191] S700: Use the clamping tube assembly to center and clamp the tube and send the tube to the required position for loading;

[0192] like Fig.19 As shown, the working steps of S100 are as follows:

[0193] S110: The stop rod of the stop tube positioning assembly rises.

[0194] S120: Tighten the sling and place the pipe on the induction conductive plate of the conveying beam.

[0195] S130: Loosen the slings and put the remaining pipes back into the storage frame.

[0196] Since each of the conveying beams 230 is paved with the inductive conductive plate 233 and the inductive conductive plate 233 is energized, the inductive conductive plate 233 has a conductive function. When the metal pipe 1 is placed on two of the inductive conductive plates 233 at the same time, a closed loop is formed, thereby detecting whether there is a pipe 1 input thereon.

[0197] like Fig. 20 As shown, the working steps of S300 are as follows:

[0198] S310: The stop rod of the stop tube positioning assembly descends.

[0199] S320: The fork plate descends to the Y+ direction of the barrier rod, and the lower end of the fork plate is flush with the inductive conductive plate.

[0200] S330: The shift fork plate shifts the pipe toward the material storage frame.

[0201] According to the diameter D of the tube 1 , the distance between the final stop position of the fork plate 821 and the edge of the inductive conductive plate 233 is D.

[0202] like Fig.21 As shown, the working steps of S400 are as follows:

[0203] S410: The fork plate position rises.

[0204] S420: The fork plate position is moved to the Y-direction of the pipe.

[0205] S430: The position of the shift fork plate is lowered until the lower end of the shift fork plate is flush with the induction conductive plate.

[0206] S440: The fork plate pushes the pipe to move to the length measuring position.

[0207] S450: The pipe moves to the in-position sensing baffle, the pipe touches the in-position sensing baffle, the sensor receives a signal, and the fork plate stops moving.

[0208] like Fig. 22 As shown, the working steps of S500 are as follows:

[0209] S510: The length measuring motion component pushes the pipe to move toward the length measuring sensing component.

[0210] S520: The length measuring sensing component detects a signal, and the length measuring motion component stops moving.

[0211] S530: The length measuring motion component returns to the original position.

[0212] It should be noted that, given that the distance between the initial position of the length measuring push plate 716 and the length measuring baffle 721 is L1, and the moving distance of the length measuring motion assembly 710 is L2, the length L of the pipe 1 is L1-L2.

[0213] like Figure 3 As shown, it is known that the length of the pipe is L, it is known that the distance from the fixed sliding component 3 to the length measuring baffle 721 is A, and the distance from the movable sliding component 4 to the length measuring baffle 721 is B, then: distance A<distance B<length L.

[0214] like Fig.23 As shown, the working steps of S700 are as follows:

[0215] S710: The fork plate moves in the Y-direction until it is far enough away from the pipe to allow the clamping jaw 832 to descend.

[0216] S720: The centering jaw is lowered so that the lower part of the jaw 832 is lowered below the nylon plate 232.

[0217] S730: The clamping tube assembly moves in the Y+ direction until the centering jaws can fully clamp the tube, and then the centering jaws clamp the tube.

[0218] S740: The centering jaws rise to the height required for loading, and the clamp tube assembly moves in the Y+ direction to the position required for loading to carry out loading.

[0219] S750: Loading is completed, and return to step S100.
