[0002] Fiber laser cutter is an advanced device that uses a high-energy-density laser beam generated by a fiber laser to cut materials. It has the advantages of high precision, high speed, good stability and low cost.

[0003] The specification of Chinese invention patent CN115352924B discloses an automatic coiled material fiber laser cutting machine, which can well solve the problem of fixing the end of the waste material in the initial stage, so that the coiling work can proceed smoothly and the actual use effect is good. In addition, the specification of Chinese utility model patent CN219234289U discloses an automatic coiled material fiber laser cutting machine. By setting a connecting device, the staff can adjust the distance between the base and the fiber laser cutting machine when necessary, so as to better meet the needs of different environments and other situations, thereby improving the practicality of the cutting machine.

[0004] When existing fiber laser cutting equipment is performing a cutting operation, the cutting depth is either lower than the material thickness or penetrates the material. When the cutting depth is lower than the material thickness, the residual waste chips in the cutting depression may not be fully cleaned by a single suction operation. When the cutting depth penetrates the material, when the length of the cut material is greater than the distance between two adjacent round rods at the bottom of the material, the cut material cannot fall smoothly into the aggregate frame under the round rods, requiring manual intervention, resulting in cumbersome operation. Summary of the invention

[0008] A clamping unit and a shaking unit are installed on the top of the operating table, and both the clamping unit and the shaking unit are located between the No. 1 electrical guide rail and the No. 2 electrical guide rail.

[0009] In the above-mentioned automatic coil fiber laser cutting machine, by utilizing the cooperation of the clamping unit, the shaking unit and the No. 1 electric extension rod, the waste chips and materials after cutting can be processed in a targeted manner according to the requirements of different thicknesses during cutting.

[0010] As a further improvement of the present application, the clamping unit includes a vertical plate fixedly installed on the top of the operating table, and two electromagnetic blocks arranged upper and lower are installed on the surface of the vertical plate. A scissors piece is arranged in the middle of the two electromagnetic blocks, and both tail ends of the scissors piece are connected to clamping rods, and the other end surface of the scissors piece is coated with a magnetic attraction layer.

[0011] As a further improvement of the present application, the shaking unit includes two slide members fixedly installed on the inner wall of the operating table, and the vertical plate is located between the slide member and the No. 1 electrical rail. The inner wall of the slide member is slidably connected with a shaking plate located above the supporting round rod. A vibrator is installed on the top of the slide member, and the output end of the vibrator is connected to the surface of the shaking plate.

[0012] As a further improvement of the present application, in the initial state, the distance between the supporting round rod and the filter plate in the vertical direction is smaller than the horizontal distance between the two supporting round rods in the horizontal direction, and in the initial state, the filter plate is located within the opening range of the material introduction frame.

[0014] As a further improvement of the present application, it also includes a cutting control system, which includes a clamping module, a screening module and a cleaning module. The clamping module is connected to the electromagnetic block signal for clamping the material laid on the surface of the supporting round rod. The screening module is connected to the four No. 1 electric extension rod signals for controlling the height position and inclination of the filter plate in the waste frame. The cleaning module is connected to the No. 2 electric extension rod and the No. 2 electric guide rail signal for cleaning waste chips on the surface of the material.

In addition, the No. 3 electric extension rod and the spliced ​​filter plate can be used to effectively transfer waste chips whose size is larger than the filtering size of the filter plate.

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-Figure 4 An automatic coiled material fiber laser cutting machine is shown, comprising an operating table 1 for performing fiber laser cutting on materials, a No. 1 electric guide rail 4 and a No. 2 electric guide rail 5 are installed on the top of the operating table 1, two laser cutting heads 6 are slidably installed on the surface of the No. 1 electric guide rail 4, a No. 2 electric extension rod 14 is slidably connected inside the No. 2 electric guide rail 5, a cleaning block 15 is connected to the power end of the No. 2 electric extension rod 14, and a coiled material roller 2 is installed on one side surface of the operating table 1 through an axis frame;

[0033] The inner wall of the operating table 1 is rotatably mounted with a plurality of equally spaced supporting round rods 16, a waste frame 18 is installed inside the operating table 1 and is located below the supporting round rods 16, a filter plate 9 is slidably connected to the inner wall of the waste frame 18, a No. 1 electric extension rod 8 is installed at each of the four corners of the bottom wall of the waste frame 18, and the power end of the No. 1 electric extension rod 8 is movably hinged to the bottom of the filter plate 9, a side surface of the waste frame 18 close to the coiling roller 2 is penetrated with an inclined material guide frame 7, and a side surface of the operating table 1 is mounted with a collecting frame 3 located below the coiling roller 2;

[0034] A clamping unit and a shaking unit are installed on the top of the operating table 1, and the clamping unit and the shaking unit are both located in the middle of the No. 1 electrical guide rail 4 and the No. 2 electrical guide rail 5.

[0035] Figure 5The clamping unit is shown to include a vertical plate fixedly installed on the top of the operating table 1, and two electromagnetic blocks 102 arranged up and down are installed on the surface of the vertical plate. A scissor piece 101 is arranged in the middle of the two electromagnetic blocks 102, and the two tail ends of the scissor piece 101 are connected to the clamping rod 10, and the other end surface of the scissor piece 101 is coated with a magnetic attraction layer.

[0036] The shaking unit includes two slide members 12 fixedly installed on the inner wall of the operating table 1, and the vertical plate is located between the slide member 12 and the No. 1 electrical rail 4. The inner wall of the slide member 12 is slidably connected with a shaking plate 13 located above the supporting round rod 16. A vibrator 11 is installed on the top of the slide member 12, and the output end of the vibrator 11 is connected to the surface of the shaking plate 13.

[0037] Specifically, when cutting, the laser cutting head 6 and the No. 1 electric guide rail 4 are used to cooperate to perform fiber laser cutting operations on the material laid on the surface of the supporting round rod 16. After the cutting is completed, the coil roller 2 rotates to drive the cut part to move to the right. After reaching the position of the shaking plate 13, the electromagnetic block 102 is started, which drives the electromagnetic block 102 to generate a repulsive effect with the end of the scissors member 101, thereby bringing the ends of the clamping rod 10 closer to each other, clamping the material arranged between the two clamping rods 10, and thus constraining the material.

[0038] Then, the vibrator 11 is started to drive the shaking plate 13 located below the material to shake. When the cutting thickness is less than the material thickness, a depression will be generated on the surface of the material, and the waste chips in the depression will be moved out of the depression after shaking. Then, the waste chips accumulated on the surface of the depression can be pushed and cleaned accordingly by the second electric guide rail 5, the second electric extension rod 14 and the cleaning block 15 (such as Figure 6 As shown, it is also possible that some of the waste chips return to the recess after shaking. In this case, it is necessary to continue shaking and then continue the push cleaning operation).

[0039] When the cutting thickness is greater than the material thickness, that is, a through-notch will be formed in the material after cutting. If the length of the cut material is less than the distance between two adjacent supporting round rods 16, the cut material will directly fall to the surface of the filter plate 9 below. If the length of the cut material is greater than the distance between two adjacent supporting round rods 16, the cut material will be placed obliquely in the cut notch after shaking, protruding from the surface of the material. When the cleaning block 15 is moved, it will be intercepted by the obliquely placed cut material (such as Figure 7As shown), and due to the length limitation of the cut material, it cannot fall to the filter plate 9 below by itself. Therefore, in this state, it is necessary to start the No. 1 electric extension rod 8 first to drive the filter plate 9 to descend until the inclined cut material gradually and autonomously lies flat on the surface of the filter plate 9 due to the descent. Then, the No. 1 electric extension rod 8 is reset, and the No. 1 electric extension rod 8 away from the side of the feed frame 7 continues to rise, so that the filter plate 9 forms an inclined state, so that the cut material on the surface can be transferred to the collection frame 3 through the feed frame 7 (as shown in FIG. Figure 8 shown).

[0040] In the initial state, the distance between the supporting round rods 16 and the filter plate 9 in the vertical direction is smaller than the horizontal distance between the two supporting round rods 16 in the horizontal direction, and the filter plate 9 is located within the opening range of the material introduction frame 7 in the initial state.

[0041] Specifically, the difference in size between the distance between the material on the surface of the supporting round rod 16 and the filter plate 9 in the initial state and the distance between two adjacent supporting round rods 16 enables the cut material to be placed at an angle under the support of the filter plate 9 when a larger material is subsequently cut.

[0042] The lower clamping rod 10 is located below the plane where the tangent line of the top end of the supporting round rod 16 is located, and the length of the two clamping rods 10 is not less than the length of the supporting round rod 16 .

[0043] Specifically, after the clamping rod 10 is clamped and the shaking unit is started, the shaking effect will not be transmitted to the material in the area below the laser cutting head 6, and will not affect the cutting accuracy.

[0044] It also includes a cutting control system, which includes a clamping module, a screening module and a cleaning module. The clamping module is connected to the electromagnetic block 102 by signal, and is used to clamp the material laid on the surface of the supporting round rod 16. The screening module is connected to the four No. 1 electric extension rods 8 by signal, and is used to control the height position and inclination of the filter plate 9 in the waste frame 18. The cleaning module is connected to the No. 2 electric extension rod 14 and the No. 2 electric guide rail 5 by signal, and is used to clean the waste on the surface of the material.

[0045] The second implementation method:

[0046] Fig. 9 It is shown that the surface of the fixed end of the No. 1 electric extension rod 8 is installed with the No. 3 electric extension rod 17 through an extension block, and the power end of the No. 3 electric extension rod 17 is movably hinged to the surface of the filter plate 9, and the filter plate 9 is replaced by two spliced ​​plate structures instead of an integrated plate structure.

[0047] The third electric extension pole 17 is located outside the first electric extension pole 8 , and the first electric extension pole 8 and the third electric extension pole 17 are signal connected.

[0048] Different from the first embodiment, this embodiment mainly processes waste chips whose size is larger than the filtering size of the filter plate 9 during cutting.

[0049] Specifically, when the cutting thickness is less than the material thickness, if the size of the waste chips generated is larger than the filtering size of the filter plate 9, in order to prevent the waste chips from following the filter plate 9 into the collection frame 3, at this time, the power end of the No. 1 electric extension rod 8 is in an equal height state. Therefore, as the waste chips continue to fall, the surface of the filter plate 9 will gradually accumulate, affecting the subsequent falling of smaller waste chips. Therefore, it is necessary to start the No. 3 electric extension rod 17 to allow the two spliced ​​filter plates 9 to tilt, thereby forming a gap between the two spliced ​​filter plates 9, so that the debris on the surface of the filter plate 9 can fall through the gap to the bottom of the filter plate 9 (such as Fig.10 shown).

[0050] In summary, when the present application is used to perform corresponding fiber laser cutting operations, the laser cutting head 6 can be used to perform corresponding laser cutting operations. When the cutting thickness is less than the material thickness, when it is necessary to clean the waste chips after cutting on the surface of the material, the clamping unit is used to prevent the shaking of the shaking unit from being transmitted to the material in the cutting area to ensure the cutting accuracy. After that, the shaking unit will shake to drive the waste chips in the cutting recess to move out, and cooperate with the No. 2 electric guide rail 5 and the cleaning block 15 to push and clean the waste chips on the surface of the material. When collecting the cut material whose length after cutting is greater than the spacing between adjacent supporting round rods 16, the No. 1 electric extension rod 8 and the filter plate 9 are used to first descend, then reset, and then tilt in the waste frame 18 to transfer the cut material to the collection frame 3. In addition, the No. 3 electric extension rod 17 and the spliced ​​filter plate 9 can be used to effectively transfer waste chips whose size is larger than the filtering size of the filter plate 9.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
