Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to an axially rotating, precisely positioned, anti-twisting laser head. Background Art

[0002] Intelligent five-axis laser welding equipment is an advanced welding device. It features five axes of motion (typically three linear axes, X, Y, and Z, and two rotary axes), enabling complex spatial trajectory welding. Combining laser welding technology with an intelligent control system, this equipment enables high-precision and efficient welding of workpieces of various shapes and structures.

[0003] Intelligent five-axis laser welding equipment mainly relies on the laser welding head to perform laser welding on the workpiece, and there are multiple wires connected to the laser welding head. These wires include lines for transmitting laser energy control signals, but these wires are not properly organized, and the problem of wire twisting is easy to occur when the laser welding head rotates. When the laser welding head rotates, the wires that are not fixed and organized will swing disorderly with the movement of the welding head. And because the rotation of the laser welding head is carried out in three-dimensional space, the wires are easy to entangle with each other, and the rotation of the laser welding head is easy to cause stress at the connection between the wires and the laser welding head. Over time or when the laser welding head rotates at high frequency for laser welding, it is easy to cause the connection to loosen, which will not only affect the normal operation of the welding head, but may even cause equipment failure due to damage to the wires, affecting the laser welding quality and the service life of the equipment.

[0004] At the same time, when the laser welding head is performing laser welding on the workpiece, metal smoke will be generated. The gap between the rotary table closest to the laser welding head and the laser welding head will easily allow smoke to penetrate. Over time, it will affect the performance of the rotary table, thereby affecting the precise rotation of the rotary table to the laser welding head, and thus affecting the quality of laser welding.

[0032] The adjustment mechanism includes a cylinder 15 and multiple connecting columns 22. The cylinder 15 is rotatably connected to the middle of one side wall of the distribution plate 19, and the end of the cylinder 15 away from the distribution plate 19 is fixedly connected to the stud 17. The end of the stud 17 away from the cylinder 15 is fixedly connected to the rotating block 18, and the outer wall of the stud 17 is threadedly sleeved with a connecting ring 16.

[0033] The elastic component includes a sleeve ring 7, which is fixedly sleeved on the outer wall of the connecting column 22 away from the arc-shaped clamping block 8, and a spring 14 is fixedly connected between the sleeve ring 7 and the circular ring 3, and the spring 14 is slidably sleeved on the outer wall of the connecting column 22.

[0034] The pushing mechanism includes a connecting block 12, which is rotatably connected to the end of the connecting rod 13 away from the connecting ring 16, and one end of the connecting block 12 is fixedly connected to the pushing plate 10, and the plate wall of the pushing plate 10 is in contact with the end of the hemispherical block 23 away from the connecting column 22. A guiding mechanism is provided between the connecting block 12, the circular ring 3 and the distribution plate 19.

[0035] The guide mechanism includes a guide column 11 and a cylindrical groove 24. The guide column 11 slides and is inserted into the connecting block 12 corresponding to the inner wall of the ring 3. The cylindrical groove 24 is opened on the outer wall of the distribution plate 19 corresponding to the connecting block 12. One end of the guide column 11 is fixedly connected to the wall of the ring 3 corresponding to the connecting block 12, and the other end of the guide column 11 is slidably inserted into the inner wall of the cylindrical groove 24.

[0036] In this embodiment, the multiple wires connected to the laser welding head 4 can pass through the multiple U-shaped grooves 20 on the distribution plate 19 in the two rings 3 in sequence, and then the multiple wires can be inserted into the hidden wire groove 28 on the base 25 and hidden. After passing through the hidden wire groove 28, the multiple wires can be tied with a cable tie, and the end of the multiple wires away from the laser welding head 4 can be connected to the corresponding device connection point (this is a well-known existing technology and will not be described in detail). In this process, the wire portion between the T-plate 21 and the laser welding head 4 is in a slightly loose state, and the wire portion between the two rings 3 is in an L-shape and in a moderately loose state (such as Figure 9 as shown), and the L-shaped wire portion is also secured with a cable tie.

[0037] Next, rotate the rotating block 18 on a ring 3, the rotating block 18 will drive the stud 17 and the cylinder 15 to rotate, the stud 17 will drive the connecting ring 16 to move away from the ring 3, the connecting ring 16 will drive the multiple connecting rods 13 to rotate synchronously, the multiple connecting rods 13 can drive the connecting blocks 12 connected to them to move synchronously toward the center of the ring 3, the multiple connecting blocks 12 can drive the guide columns 11 connected to them to slide in the ring 3 and also slide in the corresponding cylindrical grooves 24, and the multiple connecting blocks 12 will also drive the push plates 10 connected to them to move toward the ring 3. The plurality of pushing plates 10 will push their respective hemispherical blocks 23 to move toward the center of the ring 3, and the plurality of hemispherical blocks 23 can drive their respective connected connecting columns 22 to move toward the center of the ring 3 in the ring 3, and the plurality of connecting columns 22 will drive their respective connected sleeve rings 7 to squeeze the spring 14 connected to the ring 3, and the plurality of connecting columns 22 will also drive their respective connected arc-shaped clamping blocks 8 to move toward the center of the ring 3 in the corresponding U-shaped grooves 20, until the plurality of arc-shaped clamping blocks 8 clamp the plurality of wires in the corresponding U-shaped grooves 20.

[0038] To sum up, if the rotating block 18 on the other ring 3 is rotated in the same way, the multiple wires in the other branching disk 19 will also be fixed. At this time, when the B-axis turntable 6 drives the laser welding head 4 to rotate, since the multiple wires in the two branching disks 19 are fixed, and the wire part between the two branching disks 19 is moderately loose L-shaped, then when the laser welding head 4 drives the T-plate 21 and the ring 3 and the branching disk 19 connected to the T-plate 21 to rotate, it will drag the moderately loose L-shaped wires to a straightened state, and The wire is not directly tightened, and when the laser welding head 4 rotates at an excessive angle, the L-shaped wire will pull the ring 3 and the distribution plate 19 connected to the base 25. The ring 3 and the distribution plate 19 connected to the base 25 will then pull the spring 29 connected to the multiple support plates 26 through the multiple L-shaped plates 27, which will not cause wire damage. In addition, during the rotation of the laser welding head 4, the main force points of the wires are always within the two distribution plates 19, and will not cause much force to the connection between the wires and the laser welding head 4, thereby preventing the connection from loosening. At the same time, the multiple wires connected to the laser welding head 4 are sorted out to effectively avoid the problem of twisted wires, thereby avoiding affecting the normal operation of the laser welding head 4, avoiding equipment failure caused by the problem of twisted wires, and improving the quality of laser welding and the service life of the equipment.

[0039] It is worth mentioning that the multiple connecting rods 13 and the multiple U-shaped grooves 20 are staggered, so the wires are not blocked by the connecting rods 13 when passing through the U-shaped grooves 20, avoiding inconvenience.

[0040] Example 2: Please refer to Figure 6 and Figure 7 , this embodiment further explains Example 1, the limiting mechanism includes a fixed block 31 and a plurality of triangular grooves 33, the fixed block 31 is fixedly connected to the side wall of the distribution plate 19 near the cylinder 15, and the inner wall of the fixed block 31 is symmetrically slidably interspersed with a splicing column 30, and the two splicing columns 30 corresponding to one end of the cylinder 15 are commonly fixedly connected with a T-shaped block 32, and a spring three 34 is symmetrically fixedly connected between the T-shaped block 32 and the fixed block 31, and the two springs three 34 are respectively slidably sleeved on the outer walls of the two splicing columns 30, and a plurality of triangular grooves 33 are opened on the outer wall of the cylinder 15 in a central annular array around the cylinder 15. The T-shaped block 32 is triangular in shape at one end corresponding to the cylinder 15, and the T-shaped block 32 slides between one end of the cylinder 15 and one of the triangular grooves 33.

[0041] In this embodiment, when the rotating block 18 drives the stud 17 and the cylinder 15 to rotate, the cylinder 15 will drive the multiple triangular grooves 33 on its outer wall to rotate, and each triangular groove 33 will squeeze and push the triangular end of the corresponding T-shaped block 32 outward, so that the T-shaped block 32 moves away from the cylinder 15, and drives the two connected splicing columns 30 to slide in the corresponding fixed block 31, and the T-shaped block 32 will also squeeze the two springs 34 between the fixed block 31, and then when the next triangular groove 33 corresponds to the triangular end of the T-shaped block 32, under the action of the spring 34, the triangular end of the T-shaped block 32 will automatically insert into the next triangular groove 33, and so on. Then, under the action of spring three 34 and spring three 34, the rotating block 18, the stud 17 and the cylinder 15 can remain in a fixed state after rotation, preventing the rotating block 18, the stud 17 and the cylinder 15 from loosening and rotating during the rotation of the laser welding head 4, and preventing the connecting ring 16 outside the stud 17 from moving, so that the wire can be stably fixed in the U-shaped groove 20 by the arc clamping block 8.

[0042] Example 3: Please refer to Figure 1 and Figure 8 , this embodiment further explains Example 1, the sealing mechanism includes a fixed ring 5, the fixed ring 5 is fixedly sleeved on the outer wall of the B-axis turntable 6, and the inner wall of the fixed ring 5 is slidably interspersed with multiple pillars 9 in a circular array around its center, one end of the multiple pillars 9 is commonly fixedly connected to a support ring 37, and the side of the support ring 37 away from the pillar 9 is fixedly connected to a rubber ring 36, the rubber ring 36 and the support ring 37 are both slidably sleeved on the outer wall of the B-axis turntable 6, and the side of the rubber ring 36 away from the support ring 37 is tightly fitted with the side wall of the laser welding head 4, and multiple springs four 35 are fixedly connected between the fixed ring 5 and the support ring 37, and the multiple springs four 35 are respectively slidably sleeved on the outer walls of the multiple pillars 9.

[0043] In this embodiment, multiple springs four 35 are in a compressed state, which will drive the rubber ring 36 on the support ring 37 to fit tightly against the side wall of the laser welding head 4, and the gap between the B-axis turntable 6 and the laser welding head 4 is always tightly sealed. Even if the laser welding head 4 is rotated for a long time and the rubber ring 36 is worn, at this time, under the action of the spring four 35, the rubber ring 36 can still maintain a close fit with the laser welding head 4, thereby effectively preventing the smoke generated by the laser welding head 4 when laser welding the workpiece from drifting into the gap between the B-axis turntable 6 and the laser welding head 4, thereby avoiding affecting the performance of the B-axis turntable 6, ensuring the precise rotation of the B-axis turntable 6 to the laser welding head 4, and thus ensuring the quality of laser welding.
