Detailed implementation manners

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1-8, an embodiment of the present invention is: a robot automatic assembly device, including a bottom plate 1, a rotating table 2 is fixedly connected to the upper surface of the bottom plate 1, a robotic arm 3 is fixedly connected to the rotating end of the rotating table 2, a welding torch moving groove 4 is fixedly connected to the back surface of the robotic arm 3, a welding torch is arranged inside the welding torch moving groove 4, and a workbench 5 is fixedly connected to the upper surface of the bottom plate 1; a clamping mechanism 6 is arranged on the lower surface of the welding torch moving groove 4, a blanking mechanism 7 is arranged on the upper surface of the workbench 5, and a feeding mechanism 8 is arranged on the upper surface of the workbench 5; the clamping mechanism 6 includes: a fixed rod 61, a first connecting rod 62, a telescopic push rod 63, and a spring clamp plate 64. The upper surface of the fixed rod 61 is fixedly connected to the lower surface of the welding torch moving groove 4. The first connecting rod 62 is rotatably connected to the left side of the fixed rod 61. The telescopic push rod 63 is rotatably connected to the surface of the first connecting rod 62. The upper surface of the spring clamp plate 64 is fixedly connected to the lower surface of the fixed rod 61 through a spring telescopic column. The clamping mechanism 6 further includes: a U-shaped plate 65, a pressing plate 66, a first fixing plate 67, and an elastic telescopic plate 68. The U-shaped plate 65 is fixedly connected to the surface of the fixed rod 61. The upper surface of the pressing plate 66 is fixedly connected to the lower surface of the U-shaped plate 65 through a short column. The lower surface of the first fixing plate 67 is fixedly connected to the upper surface of the workbench 5. The elastic telescopic plate 68 slides in the groove of the first fixing plate 67. The left side of the telescopic push rod 63 is rotatably connected to the inner wall of the spring clamp plate 64. The lower surface of the elastic telescopic plate 68 contacts the upper surface of the workbench 5. When the device is started, the rotating table 2 on the bottom plate 1 rotates. The rotation of the rotating table 2 drives the robotic arm 3, and the robotic arm 3 drives the welding torch moving groove 4 to reach the approximate welding position to operate on the steel plate. At this time, the welding torch in the welding torch moving groove 4 welds two rectangular steel plates placed on the workbench 5 into one steel plate. The downward pressure of the welding torch moving groove 4 drives the fixed rod 61 downward, and the downward pressure of the fixed rod 61 drives the spring clamp plate 64 downward. When the spring clamp plate 64 touches the steel plate, the spring clamp plate 64 gradually presses the steel plate through the spring telescopic column. At this time, the first connecting rod 62 and the telescopic push rod 63 move closer to the steel plate, and the telescopic push rod 63 clamps the front and back sides of the steel plate. The lower end of the telescopic push rod 63 touches the workbench 5, causing the lower end of the telescopic push rod 63 to contract inward, so that the device fixes the steel plate up and down, front and back, and its position and relative angle remain stable. When welding some welds with high precision requirements, the straightness and flatness of the weld can be ensured. The downward movement of the fixed rod 61 drives the U-shaped plate 65 downward, and the U-shaped plate 65 drives the pressing plate 66 downward. The pressing plate 66 presses the elastic telescopic plate 68 downward. Since the first fixing plate 67 is provided with an inclined groove, the elastic telescopic plate 68 moves in the groove. Due to the pressure of the pressing plate 66, the elastic telescopic plate 68 contracts, and the elastic telescopic plate 68 moves to the right. The push block on the elastic telescopic plate 68 clamps the left and right sides of the steel plate. Clamping the left and right sides can solve the problem that the width and height of the weld are uneven due to the movement of the steel plate. The fixed steel plate can make the weld more uniform and beautiful, meeting the requirements of high-quality welding.

[0016] Working principle: When the device is started, the rotating table 2 on the bottom plate 1 rotates. The rotation of the rotating table 2 drives the robotic arm 3, and the robotic arm 3 drives the welding torch moving groove 4 to reach the approximate welding position to operate on the steel plate. At this time, the welding torch moving groove 4 drives the welding torch inside to weld the two rectangular steel plates placed on the workbench 5, welding the two steel plates into one. The welding torch moving groove 4 presses down to drive the fixed rod 61 to press down, and the fixed rod 61 pressing down drives the spring clamp 64 to press down. When the spring clamp 64 touches the steel plate, the spring clamp 64 gradually presses the steel plate through the spring telescopic column. At this time, the connecting rod 62 and the telescopic push rod 63 move closer to the steel plate, and the telescopic push rod 63 clamps the front and back sides of the steel plate. The lower end of the telescopic push rod 63 touches the workbench 5 and causes the lower end of the telescopic push rod 63 to contract inward, so that the device fixes the steel plate up and down, front and back, and its position and relative angle remain stable. When welding some welds with high precision requirements, it can ensure the straightness and flatness of the weld. The fixed rod 61 moves downward to drive the U-shaped plate 65 to move downward, and the U-shaped plate 65 drives the pressing plate 66 to move downward. The pressing plate 66 presses the elastic telescopic plate 68 downward. Since the fixing plate 67 is provided with an inclined groove, the elastic telescopic plate 68 moves in the groove. Due to the pressure of the pressing plate 66, the elastic telescopic plate 68 contracts, and the elastic telescopic plate 68 moves to the right. The push block on the elastic telescopic plate 68 clamps the left and right sides of the steel plate. Clamping the left and right sides can solve the problem of uneven width and height of the weld caused by the movement of the steel plate. The fixed steel plate can make the weld more uniform and beautiful, meeting the requirements of high-quality welding.

The second connecting rod 72 is rotatably connected to the right side of the fixed column 71 through a torsion spring. The third connecting rod 73 is rotatably connected to the right side of the second connecting rod 72. The left end of the connecting column 74 is rotatably connected to the lower end of the third connecting rod 73. The back surface of the first push plate 75 is fixedly connected to the circumferential surface of the connecting column 74 through a short rod. The lower surface of the first slide rail 76 is fixedly connected to the upper surface of the workbench 5. The lower surface of the blanking box 77 is fixedly connected to the upper surface of the bottom plate 1. The blanking mechanism 7 further includes: a telescopic pull rod 78, an L-shaped rod 79, a brush plate 710, a reciprocating lead screw 711, and a first moving block 712.

After the welding is completed, the robotic arm 3 drives the welding torch moving groove 4 to lift, and the welding torch moving groove 4 drives the U-shaped plate 65 to lift. When the U-shaped plate 65 reaches a certain height, at this time, the U-shaped plate 65 contacts the second connecting rod 72. The U-shaped plate 65 continues to lift upward and drives the second connecting rod 72 to rotate around the fixed column 71. The rotation of the second connecting rod 72 drives the third connecting rod 73 to slide forward in the first slide rail 76. The third connecting rod 73 drives the connecting column 74 to move forward. The connecting column 74 drives the first push plate 75 to move forward. The first push plate 75 moves forward and pushes the processed steel plate into the blanking box 77. A spring plate is installed inside the blanking box 77 to prevent the steel plate from being damaged when falling from a height. During the welding process of the device, automatic blanking can ensure that the steel plate is removed in time, so that the welding work can be carried out continuously, greatly improving the overall efficiency of welding. Moreover, it can also clean the workbench 5 to prevent the accumulation of welding slag from affecting the welding effect of the steel plate. When the first push plate 75 pushes the steel plate for blanking, the telescopic pull rod 78 pulls the L-shaped rod 79 to rotate on the side of the first push plate 75. The L-shaped rod 79 lifts the welded steel plate. The movement of the first push plate 75 drives the brush plate 710 to move and sweep the welding slag. At the same time, the roller at the bottom of the first push plate 75 rotates during the pushing process. The rotation of the first push plate 75 drives the reciprocating lead screw 711 to rotate. The rotation of the reciprocating lead screw 711 makes the first moving block 712 move left and right on the circumferential surface of the reciprocating lead screw 711.The slag on the brush plate 710 is cleaned, improving the cleaning effect. During the process of pushing out the steel plate, the blanking mechanism 7 can lift the steel plate, reducing the friction between the steel plate and the workbench 5, improving the processing precision, and protecting the steel plate.

The lower surface of the second slide rail 81 is fixedly connected to the upper surface of the workbench 5. The lower surface of the second fixed plate 82 is fixedly connected to the upper surface of the workbench 5. The back surface of the second moving block 83 slides on the inner wall of the second slide rail 81. The left side of the third fixed plate 84 is fixedly connected to the right side of the telescopic plate fixed on the upper surface of the second moving block 83 through a short column. The cylinder on the short plate fixedly connected to the upper surface of the rack column 85 slides on the inner wall of the second moving block 83. The lower surface of the gear column 86 is fixedly connected to the upper surface of the workbench 5, and a gear is rotatably connected to the upper surface of the gear column 86. The lower surface of the fourth fixed plate 88 is fixedly connected to the upper surface of the workbench 5.

The lower surface of the third fixed plate 84 contacts the upper surface of the U-shaped plate 65. The lower surface of the second moving block 83 contacts the upper surface of the rack column 85. The surface of the rack column 85 slides on the inner wall of the second fixed plate 82. The rack surface of the rack column 85 meshes with the gear on the upper surface of the gear column 86. The teeth of the second push plate 87 mesh with the gear column 86. The circumferential surface of the pushing column 811 slides on the inner wall of the limiting plate 810. The pushing plate of the pushing column 811 contacts the inner wall of the blanking box 77. Workers place the steel plate on the belt of the first transfer table 89. The length of the first transfer table 89 can select belts of different sizes according to the actual engineering needs. The first transfer table 89 rotates to convey the steel plate. When the U-shaped plate 65 moves upward to drive the third fixed plate 84 to move upward, the third fixed plate 84 moving upward drives the telescopic plate on the second moving block 83 to move upward. When the telescopic plate on the second moving block 83 reaches a certain length, it no longer extends. The U-shaped plate 65 drives the third fixed plate 84 to continue moving upward. The third fixed plate 84 drives the second moving block 83 to move upward as a whole in the second slide rail 81. The second moving block 83 moving upward drives the rack column 85 to move forward in the second fixed plate 82. Since there is a rack on the rack column 85, the rack column 85 drives the gear on the gear column 86 to rotate. The gear on the gear column 86 rotating drives the second push plate 87 to move rightward in the fourth fixed plate 88, enabling the feeding mechanism 8 of the device to ensure the continuous and stable supply of the steel plate to the welding area through the first transfer table 89, and at the same time, it can straighten the steel plate during the material transportation process to ensure accurate falling onto the workbench 5, and during the welding process, there will be no situation of welding interruption caused by untimely manual feeding. The movement of the second push plate 87 drives the pushing column 811 to move in the limiting plate 810. Since the right pushing plate of the pushing column 811 is set to be inclined, the movement of the pushing column 811 squeezes the processed steel plate in the blanking box 77 towards the middle. Moreover, rollers are installed on the spring plate in the blanking box 77.The device pushes the steel plates that fall into the blanking box 77 into the second transfer table 812. Timely transporting the steel plates piled up in the blanking box 77 can reduce the time that operators are exposed to harmful environments and ensure the health and safety of workers.

[0019] Working principle: After welding is completed, the robotic arm 3 drives the welding torch moving groove 4 to lift, and the welding torch moving groove 4 drives the U-shaped plate 65 to lift. When the U-shaped plate 65 reaches a certain height, at this time, the U-shaped plate 65 contacts the second connecting rod 72. The U-shaped plate 65 continues to lift upward, driving the second connecting rod 72 to rotate around the fixed column 71. The rotation of the second connecting rod 72 drives the third connecting rod 73 to slide forward in the first slide rail 76. The third connecting rod 73 drives the connecting column 74 to move forward. The connecting column 74 drives the first push plate 75 to move forward. The first push plate 75 moves forward to push the processed steel plates into the blanking box 77. A spring plate is installed inside the blanking box 77 to prevent the steel plates from being damaged when falling from a height. During the welding process of the device, automatic discharging can ensure that the steel plates are removed in time, enabling the welding work to proceed continuously, greatly improving the overall welding efficiency. Moreover, it can also clean the workbench 5 to prevent the accumulation of welding slag from affecting the welding effect of the steel plates. When the first push plate 75 pushes the steel plates to fall, the telescopic pull rod 78 pulls the L-shaped rod 79 to rotate on the side of the first push plate 75. The L-shaped rod 79 lifts the welded steel plates. The movement of the first push plate 75 drives the brush plate 710 to move, sweeping the welding slag. At the same time, the rollers at the bottom of the first push plate 75 rotate during the pushing process. The rotation of the first push plate 75 drives the reciprocating lead screw 711 to rotate. The rotation of the reciprocating lead screw 711 allows the first moving block 712 to move left and right on the circumferential surface of the reciprocating lead screw 711, cleaning the welding slag on the brush plate 710 and improving the cleaning effect. The blanking mechanism 7 can lift the steel plates during the process of pushing out the steel plates, reducing the friction between the steel plates and the workbench 5, improving the processing accuracy, and protecting the steel plates.

[0020] The worker places the steel plate on the belt of conveyor table 1 89. The length of conveyor table 1 89 can be selected with belts of different sizes according to the actual engineering requirements. Conveyor table 1 89 rotates to convey the steel plate. When the U-shaped plate 65 moves upward, it drives the fixed plate 3 84 to move upward. The upward movement of the fixed plate 3 84 drives the telescopic plate on the moving block 2 83 to move upward. When the telescopic plate on the moving block 2 83 reaches a certain length, it no longer extends. The U-shaped plate 65 drives the fixed plate 3 84 to continue moving upward. The fixed plate 3 84 drives the entire moving block 2 83 to move upward in the slide rail 2 81. The upward movement of the moving block 2 83 drives the rack column 85 to move forward in the fixed plate 2 82. Since there are racks on the rack column 85, the rack column 85 drives the gears on the gear column 86 to rotate. The rotation of the gears on the gear column 86 drives the push plate 2 87 to move rightward in the fixed plate 4 88. The feeding mechanism 8 of the device can ensure the continuous and stable supply of the steel plate to the welding area through conveyor table 1 89. At the same time, it can straighten the steel plate during the material transportation process to ensure accurate falling onto the workbench 5. During the welding process, there will be no situation of welding interruption caused by untimely manual feeding. The movement of the push plate 2 87 drives the push column 811 to move in the limit plate 810. Since the right-side push plate of the push column 811 is set to be inclined, the movement of the push column 811 squeezes the steel plate that has been processed in the blanking box 77 towards the middle. Moreover, there are rollers installed on the spring plate in the blanking box 77. The device pushes the steel plate that has fallen into the blanking box 77 into conveyor table 2 812. Timely transporting the steel plate piled up in the blanking box 77 can reduce the time for the operator to be exposed to the harmful environment and ensure the health and safety of the worker.
