[0022] The utility model provides an automatic offline robot: comprising a robotic arm 1, a clamp 2 and a reinforcement mechanism, the robotic arm 1 comprising a first rotating coupling box 3, a first support arm 4 and a second rotating coupling box 5, the reinforcement mechanism comprising a reinforcement support arm 6, two connecting seats 7, two connecting components 8 and two synchronization components 9, the connecting component 8 comprising a connecting shaft 10, a connecting sleeve 11, a limiting ring 12, a limiting short shaft 13, a first bearing 14 and a second bearing 15, the synchronization component 9 comprising two synchronization sleeves 16, a synchronization rod 17 and two fixing members 18, the fixing member 18 comprising a fixing port 19, a fixing nut 20 and a fixing bolt 21, the above-mentioned solution solves the problem that the existing automatic offline robot for backrests is supported and driven by the first support arm 4 on one side, which is prone to damage and tilting, resulting in an offset in the offline position of the car backrest and causing the car seat to fall out of the transportation line.

[0023] According to this specific embodiment, the first support arm 4 is rotatably connected to one side of the first rotating coupling box 3, the second rotating coupling box 5 is rotatably connected to the first support arm 4 and is located above the first rotating coupling box 3, the clamp 2 is arranged on one side of the robotic arm 1, and the two ends of the reinforced support arm 6 are respectively rotatably connected to the first rotating coupling box 3 and the second rotating coupling box 5, and are located on the side away from the first support arm 4, the two connecting seats 7 are respectively fixedly connected to the first rotating coupling box 3 and the second rotating coupling box 5 on the side away from the first support arm 4, the two connecting components 8 are respectively located between the two connecting seats 7 and the reinforced support arm 6, the connecting shaft 10 is fixedly connected to one side of the reinforced support arm 6, the connecting sleeve 11 is fixedly connected to the connecting seat 7 and rotatably connected to the surface of the connecting shaft 10, the two synchronization components 9 are arranged between the first support arm 4 and the reinforced support arm 6, and when the steam is being carried out When the car seat is unloaded, the first rotating coupling box 3 rotates, the first support arm 4 rotates relative to the first rotating coupling box 3, and the second rotating coupling box 5 rotates relative to the first support arm 4, thereby adjusting the position of the clamp 2 so that it clamps the seat and then unloads it. During this period, the reinforced support arm 6 moves synchronously with the movement of the first support arm 4 under the action of the two connecting seats 7, the two connecting components 8 and the two synchronous components 9, and because its position is opposite to the first support arm 4, it can prevent the first support arm 4 from tilting and being damaged. When the reinforced support arm 6 moves, the connecting shaft 10 rotates in the connecting sleeve 11, and under the action of the synchronous component 9, the reinforced support arm 6 is not easy to fall off. The structure, principle and driving method of the mechanical arm 1 have been explained in the prior art "CN213731775U A robot for automatically unloading backrests", so I will not go into details here.

[0024] Among them, the limiting ring 12 is fixedly connected to the connecting sleeve 11 and is rotatably connected to the reinforcement support arm 6, and the limiting short shaft 13 is fixedly connected to the connecting shaft 10 and is rotatably connected to the connecting sleeve 11. When the connecting shaft 10 rotates in the connecting sleeve 11, the inner wall of the limiting ring 12 contacts the connecting shaft 10. Since the shaft diameter of the limiting short shaft 13 is larger than the shaft diameter of the connecting shaft 10, the limiting short shaft 13 is restricted by the connecting ring in the connecting sleeve 11 and will not fall off, thereby preventing the reinforcement support arm 6 from falling off.

[0025] Secondly, the first bearing 14 is rotatably connected between the limiting short shaft 13 and the connecting sleeve 11, and the second bearing 15 is rotatably connected between the connecting sleeve 11 and the reinforced support arm 6. When the reinforced support arm 6 drives the connecting shaft 10 and the limiting short shaft 13 to rotate relative to the connecting sleeve 11, the first bearing 14 will make the rotation of the limiting short shaft 13 and the connecting sleeve 11 smoother and less labor-intensive, and the second bearing 15 will make the rotation of the connecting sleeve 11 and the reinforced support arm 6 smoother and less labor-intensive, which can reduce the energy loss of driving the robotic arm 1 and reduce the cost of use.

[0026] At the same time, the two synchronization sleeves 16 are respectively fixedly connected to one side of the first support arm 4 and the reinforcement support arm 6, and are arranged opposite to each other. The two ends of the synchronization rod 17 are respectively detachably connected to the two synchronization sleeves 16, and the two fixing members 18 are respectively arranged on the two synchronization sleeves 16. When the first support arm 4 moves, the two synchronization sleeves 16 thereon move together. Under the action of the two synchronization rods 17 and the four fixing members 18, the reinforcement support arm 6 is synchronized by the other two synchronization sleeves 16, and the first support arm 4 and the reinforcement support arm 6 are tightened at the same time to prevent tilting and loosening, so as to extend the service life of the robotic arm 1.

[0027] Finally, the fixing port 19 is fixedly connected to the surface of the synchronization sleeve 16 and is circulated, and the fixing nut 20 is fixedly connected to the synchronization sleeve 16. The fixing bolt 21 is threadedly connected to the synchronization sleeve 16 and the fixing nut 20, and passes through the synchronization rod 17 and the fixing port 19. When the robotic arm 1 needs to be inspected and repaired, the first support arm 4 and the reinforcement support arm 6 can be disassembled through the four fixings 18. When using the fixing 18, the fixing bolt 21 is screwed to disengage it from the fixing port 19, the fixing nut 20, the synchronization rod 17 and the synchronization sleeve 16. The disassembly of the fixing 18 is completed. When the two fixings 18 on the reinforcement support arm 6 are disassembled, the reinforcement support arm 6 can be removed. After the two fixings 18 on the first support arm 4 are disassembled, the two synchronization rods 17 can be removed, and then the entire robotic arm 1, the two connecting components 8 and other components can be inspected and repaired.

[0028] When the car seat is being taken off the assembly line, the first rotating coupling box 3 rotates, the first support arm 4 rotates relative to the first rotating coupling box 3, and the second rotating coupling box 5 rotates relative to the first support arm 4, thereby adjusting the position of the clamp 2 so that it clamps the seat and then takes it off the assembly line. During this period, the reinforced support arm 6 moves synchronously with the movement of the first support arm 4 under the action of the two connecting seats 7, the two connecting components 8 and the two synchronous components 9, and because its position is opposite to the first support arm 4, it can prevent the first support arm 4 from tilting and being damaged. When the reinforced support arm 6 moves, the connecting shaft 10 rotates in the connecting sleeve 11, and Under the action of the synchronization component 9, the reinforcement support arm 6 is not easy to fall off; when the connecting shaft 10 rotates in the connecting sleeve 11, the inner wall of the limiting ring 12 contacts the connecting shaft 10. Since the shaft diameter of the limiting short shaft 13 is larger than the shaft diameter of the connecting shaft 10, the limiting short shaft 13 is restricted by the connecting ring in the connecting sleeve 11 and will not fall off, thereby preventing the reinforcement support arm 6 from falling off; when the reinforcement support arm 6 drives the connecting shaft 10 and the limiting short shaft 13 to rotate relative to the connecting sleeve 11, the first bearing 14 will make the rotation of the limiting short shaft 13 and the connecting sleeve 11 smoother and more labor-saving, and the second bearing 15 will make the connecting sleeve 11 and the reinforcement support arm 6 The rotation of the reinforced support arm 6 is smoother and more labor-saving, which can reduce the energy loss of driving the mechanical arm 1 and reduce the cost of use; when the first support arm 4 moves, the two synchronous sleeves 16 thereon move together, and under the action of the two synchronous rods 17 and the four fixing members 18, the reinforced support arm 6 is made to move synchronously through the other two synchronous sleeves 16, and at the same time, the first support arm 4 and the reinforced support arm 6 are tightened to prevent tilting and loosening, so as to extend the service life of the mechanical arm 1; when the mechanical arm 1 needs to be repaired, the first support arm 4 and the reinforced support arm 6 can be disassembled through the four fixing members 18, and when using the fixing member 18, the fixing bolt 21 is screwed to make it disengage The fixing port 19, the fixing nut 20, the synchronization rod 17 and the synchronization sleeve 16, and the fixing part 18 are disassembled. When the two fixing parts 18 on the reinforcement support arm 6 are disassembled, the reinforcement support arm 6 can be removed. After the two fixing parts 18 on the first support arm 4 are disassembled, the two synchronization rods 17 can be removed, and then the entire robotic arm 1, the two connecting components 8 and other components can be inspected and repaired, thereby avoiding the problem that the existing automatic off-line robot for backrest is supported and driven by the first support arm 4 on one side, which is prone to damage and tilting, resulting in the offset of the off-line position of the car backrest, causing the car seat to fall out of the transportation line, thereby increasing the service life of the robot.
