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.

[0037] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a laser cutting robot and a cutting process for the production of automotive parts. Embodiment 1

[0038] See also Figure 1-Figure 2 , a laser cutting robot and a cutting process for automobile parts production, comprising a mechanical arm 1, a base 2 and a cutting head 3 fixedly arranged at the top of the mechanical arm 1, a cylindrical shaft 4 is fixedly connected to the bottom of the mechanical arm 1, and the cylindrical shaft 4 is rotatably connected to the base 2 through a bearing, a cutting table 5 is arranged on both sides of the mechanical arm 1, a conveying device 6 and an output device 7 are respectively arranged on the top and bottom of one side of the cutting table 5, and an accessory 8 is placed on the cutting table 5;

[0039] The cutting table 5 includes two support plates 51, a rotating roller 52 rotatably arranged between the two support plates 51, and a bearing seat 53 fixedly arranged at the top and bottom of the outer surface of the rotating roller 52, and an adjusting device 54 is arranged on the bearing seat 53;

[0040] A transmission assembly 9 is provided between the robot arm 1 and the rotating rollers 52 on the cutting tables 5 on both sides, so that when the robot arm 1 completes cutting of the accessory 8 on the supporting seat 53 on one side and rotates toward the supporting seat 53 on the other side, the rotating roller 52 on the side where the accessory 8 is cut rotates, and the rotating roller 52 on the other side is in a stationary state;

[0041] A transmission member 10 is provided between the conveying device 6 and the adjusting device 54, so that the adjusting device 54 can fix the accessory 8 while the conveying device 6 is transporting the accessory 8 to the bearing seat 53;

[0042] An unloading member 11 is provided between the output device 7 and the adjusting device 54 , so that after the processing of the accessory 8 is completed, the adjusting device 54 releases the accessory 8 and drives the accessory 8 to move to the output device 7 .

[0043] Specifically, after the robot arm 1 completes cutting of the accessory 8 on the left cutting table 5 through the cutting head 3, the robot arm 1, the cylindrical shaft 4 at the bottom, and the cutting head 3 at the top simultaneously rotate toward the right cutting table 5, and process the accessory 8 on the right cutting table 5. During the rotation of the cylindrical shaft 4, the transmission assembly 9 is set so that the bearing seat 53 at the top of the outer surface of the rotating roller 52 in the left cutting table 5 rotates downward, driving the accessory 8 after cutting to be located at the top of the output device 7. At this time, the output device 7 is running, and the adjustment device 54 is driven to run through the setting of the unloading member 11, and the processed accessory 8 on the bearing seat 53 at the bottom of the rotating roller 52 is disassembled and transported to the next process through the output device 7. At the same time, the bearing seat 53 at the bottom of the outer surface of the rotating roller 52 without the accessory 8 rotates upward. At this time, the conveying device 6 is running to transport the unprocessed accessory 8 to the bearing seat 53 at the top of the rotating roller 52. At the same time, the transmission member 10 is set to drive the adjustment device 54 to fix the accessory 8 on the bearing seat 53.

[0044] After the robot arm 1 completes processing of the accessory 8 on the cutting table 5 on one side, it rotates itself and processes the accessory 8 on the cutting table 5 on the other side. The transmission component 9 drives the processed accessory 8 to move downward and is stored through the output device 7. At the same time, it drives the supporting seat 53 that is not loaded with the accessory 8 to move upward, and through the cooperation between the transmission member 10 and the conveying device 6, the accessory 8 on the conveying device 6 is located at a specified position on the supporting seat 53, so that when each accessory 8 is moved to the supporting seat 53, the position of the accessory 8 on the supporting seat 53 is consistent, which solves the problem that the robot's cutting route is fixed, and manual placement of the accessory 8 will cause the position of each accessory 8 to deviate, thereby causing the cutting position deviation when the laser cutting robot is working. Embodiment 2

[0045] The difference from the above embodiment 1 is that, see Figure 3-Figure 4 For the above-mentioned transmission assembly 9, the transmission assembly 9 includes a main crawler 91 and an auxiliary crawler 92, a transverse plate 93 is fixedly connected between the two support plates 51, a vertical rod 94 is rotatably connected to the top of the transverse plate 93 through a bearing, a first worm 95 is fixedly connected to the top of the vertical rod 94, the main crawler 91 is sleeved on the cylindrical shaft 4 and the vertical rod 94, a transverse rod 96 is rotatably connected between the two support plates 51 through a bearing, a first worm gear 97 is fixedly connected to the transverse rod 96, the auxiliary crawler 92 is sleeved on the rotating roller 52 and the transverse rod 96, and the first worm gear 97 is meshed and connected with the first worm gear 95;

[0046] The main crawler 91 includes an upper crawler 911 and a lower crawler 912. The upper crawler 911 is sleeved on a vertical rod 94 above the outer circumference of the cylindrical shaft 4 and on the right side of the cylindrical shaft 4, and the lower crawler 912 is sleeved on a vertical rod 94 below the outer circumference of the cylindrical shaft 4 and on the left side of the cylindrical shaft 4, so that when the mechanical arm 1 rotates forward, the cylindrical shaft 4 drives the upper crawler 911 to rotate and makes the lower crawler 912 unable to rotate. When the mechanical arm 1 rotates reversely, the cylindrical shaft 4 drives the upper crawler 911 to be unable to rotate and makes the lower crawler 912 rotate;

[0047] Specifically, when the robot arm 1 drives the cylindrical shaft 4 to move from the cutting table 5 on one side after the cutting is completed to the cutting table 5 on the other side, the cylindrical shaft 4 drives the upper crawler 911 to rotate, and the upper crawler 911 is set on the vertical rod 94, so that the vertical rod 94 and the first worm 95 at the top of the vertical rod 94 rotate, and the meshing connection between the first worm 95 and the first worm gear 97 drives the first worm gear 97 to rotate, thereby driving the cross bar 96 fixedly connected to the first worm gear 97 to rotate, and through the sleeve connection between the cross bar 96 and the auxiliary crawler 92, when the cross bar 96 rotates, it drives the crawler to rotate, thereby driving the rotating roller 52 to rotate, and then driving the bearing seats 53 on both sides of the outer periphery of the rotating roller 52 to rotate, so that the roller 52 with the processed roller 52 is rotated. The supporting seat 53 of the completed accessory 8 rotates to the output device 7, and the supporting seat 53 without the accessory 8 rotates to the side of the conveying device 6. At this time, when the robot arm 1 rotates forward, the cylindrical shaft 4 drives the upper crawler 911 to rotate and makes the lower crawler 912 unable to rotate, and when the robot arm 1 rotates reversely, the cylindrical shaft 4 drives the lower crawler 912 to rotate and makes the upper crawler 911 unable to rotate. This allows the robot arm 1 to complete the cutting of the accessory 8 on the cutting table 5 on one side and cut the accessory 8 on the cutting table 5 on the other side. During this process, the transmission component 9 can quickly drive the rotating roller 52 to rotate, so as to collect and store the cut accessories 8 and load new unprocessed accessories 8 onto the supporting seat 53. Embodiment 3

[0048] The difference from the above-mentioned embodiment 2 is that, see Figure 5-Figure 6For the above-mentioned adjusting device 54, the adjusting device 54 includes a pressing plate 541, the bottom of the pressing plate 541 is fixedly connected to an elastic block 542, both sides of the top of the bearing seat 53 are fixedly connected to bosses 543, the top of the boss 543 is rotatably connected to a rotating drum 544 through a bearing, and the top of the boss 543 is rotatably connected to a screw rod 545 through a bearing. The screw rod 545 is arranged inside the rotating drum 544 and is rotatably connected to the rotating drum 544 through a bearing. A round block 546 is slidably connected to the inner surface of the rotating cylinder 544, and the round block 546 is threadedly connected to the screw rod 545. An opening groove 547 is provided on the outer surface of the rotating cylinder 544, and the opening groove 547 is communicated with the inner cavity of the rotating cylinder 544. An extension plate 548 is fixedly connected to one end of the pressing plate 541, and the extension plate 548 is slidably arranged in the opening groove 547 and extends into the rotating cylinder 544. An annular groove 549 is provided on the outer surface of the round block 546, and one end of the extension plate 548 is slidably arranged in the annular groove 549.

[0049] The adjusting device 54 further includes a second worm wheel 5410 and a second worm 5411. A rotating shaft 5412 is rotatably connected to the bearing seat 53 via a bearing.

An extension rod 5413 is fixedly connected to the bottom end of the screw rod 545. The extension rod 5413 extends into the bearing seat 53. The second worm wheel 5410 is fixedly arranged outside the extension rod 5413. The second worm wheel 5410 and the second worm 5411 are meshedly connected.

[0050] Specifically, by the rotation connection between the rotating cylinder 544 and the boss 543, and the sliding connection between the extension plate 548 and the annular groove 549, before adjusting the pressing plate 541 to move up and down, the horizontal position of the pressing plate 541 is adjusted, and the transmission member 10 drives the rotating shaft 5412 to rotate, thereby driving the second worm 5411 to rotate, and the meshing connection between the second worm 5411 and the second worm gear 5410 drives the second worm gear 5410 to rotate, thereby driving the extension rod 5413 fixedly connected to the second worm gear 5410 to rotate, and then driving the screw 545 to rotate, and the screw 545 and the round block 546 are connected to each other. The threaded connection and the friction between the extension plate 548 and the annular groove 549 are greater than the friction generated by the threaded connection between the round block 546 and the screw 545, and the sliding connection between the extension plate 548 and the opening groove 547, so that when the screw 545 rotates, the round block 546 is driven to move downward, thereby driving the extension plate 548 and the pressing plate 541 on one side to move downward, and fixing the top of the accessory 8 by the elastic block 542. Similarly, when the unloading part 11 drives the rotating shaft 5412 to rotate, it drives the pressing plate 541 and the elastic block 542 to move away from the bearing seat 53, thereby facilitating the disassembly of the processed accessory 8.
