Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, and in particular to an automatic welding robot for building steel components. Background Technology

[0002] In the process of producing building steel components, in order to improve the production efficiency of building steel components, welding robots are usually used to weld building steel components. The continuous operation of welding robots improves the production efficiency of building steel components. Existing welding robots usually consist of a base, a large arm, a small arm, and a welding gun.

[0003] For example, utility model application CN202120063348.0 discloses an automated steel structure welding production line, specifically including an AGV trolley, a welding workbench, a welding robot, a handling robot, a welding machine, a wire feeder, and a controller. This utility model's automated steel structure welding production line is mainly used for the fabrication of steel component fences in the construction industry. The production line, controlled by the controller, enables standardized operations at each stage. Workers only need to operate the welding robot, reducing the technical requirements for personnel and effectively solving the problems of high welder skill requirements, low production efficiency, and inconsistent welding quality associated with manual welding. The welding workbench has multiple positioning and fixing fixtures, ensuring the position remains unchanged during material positioning and welding. The welding workbench adopts a dual-station design, which not only effectively improves work efficiency but also effectively avoids cost waste caused by secondary design.

[0004] However, traditional welding robots currently in use generate welding slag during the welding process of steel components. This slag can easily fall outside the welding work area, causing pollution to the surrounding environment and potentially injuring nearby workers, making them inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides an automatic welding robot for building steel components, which has a spatter shield to prevent welding slag from splashing. While the control system controls the welding robot to perform welding, it can also activate an electric push rod. As the electric push rod is activated, it drives the control rack to move. As the control rack moves, it drives the control gear to rotate. As the control gear rotates, it drives the connecting rod to rotate. As the connecting rod rotates, it causes the spatter shield to close, covering the robot's welding torch and the welding area. At the same time, the inner side of the spatter shield is coated with a high-temperature resistant coating.

[0006] This utility model provides an automatic welding robot for building steel components, specifically including: a fixed base; a robot arm rotatably connected to the top surface of the fixed base; a robot crank rotatably connected to the upper part of the robot arm; a robot forearm rotatably connected to the front part of the robot crank; a robot wrist rotatably connected inside the robot forearm; a robot welding torch provided at the end of the robot wrist; two mounting seats symmetrically and fixedly connected to the bottom end of the robot welding torch; a connecting rod rotatably connected to each of the two mounting seats; a spatter shield fixedly connected to the end of each of the two connecting rods; and both spatter shields aligned with the position of the robot welding torch.

[0007] Optionally, a control gear is coaxially fixedly connected to the lower part of each of the two connecting rod shafts; the two control gears are respectively set in two mounting seats; two electric push rods are symmetrically bolted to the rear of the robot welding gun; a control rack is fixedly connected to the end of each of the two electric push rod drive shafts; the two control racks mesh with the two control gears respectively.

[0008] Optionally, each of the two splash guards has a set of smoke vents at its rear; a smoke vent box is fixedly connected to the rear end face of each of the two splash guards; the two smoke vent boxes are aligned with the positions of the two sets of smoke vents; activated carbon filters are inserted into the two smoke vent boxes; the two activated carbon filters are aligned with the positions of the two sets of smoke vents.

[0009] Optionally, each of the two smoke exhaust boxes is fixedly connected to a set of fixed seats on the outside; each of the two sets of fixed seats is slidably connected to a set of guide columns; each of the two sets of guide columns is fixedly connected to a locking block on the inside; each of the two sets of guide columns is fixedly connected to an auxiliary seat at the end; each of the two sets of guide columns is fixedly connected to a set of support springs on the outside; and the ends of the two sets of support springs are respectively fixedly connected to the inside of the two sets of fixed seats.

[0010] Optionally, a connecting plate is fixedly connected between the two control racks; an auxiliary push block is fixedly connected to the front end face of the connecting plate; a mounting box is provided at the lower part of the robot welding gun; a telescopic airbag is provided inside the mounting box; the auxiliary push block and the telescopic airbag are aligned.

[0011] Optionally, an air outlet frame is fixedly connected to the front end face of the mounting box; the air outlet frame is aligned with the position of the robot welding gun; the air inlet of the air outlet frame is connected to the air outlet of the telescopic airbag.

[0012] Beneficial effects

[0013] During use, this invention activates an electric push rod while the welding robot is welding. The activation of the electric push rod moves the control rack, which in turn rotates the control gear. This causes the connecting rod to close the anti-spatter cover, enclosing the robot's welding torch and the welding area. This effectively blocks high-temperature spatter generated during welding, preventing it from splashing onto the operator's body, face, and eyes. It also prevents spatter from adhering to welding equipment, robot parts, and surrounding machinery, reducing cleaning difficulty and significantly improving the convenience of the welding robot.

[0014] The fumes generated during welding enter the fume extraction chamber through the exhaust port. Inside the chamber, the fumes are filtered by an activated carbon filter, which removes some harmful substances before being released. A locking mechanism limits the activated carbon filter's position. To replace the filter, simply pull the auxiliary seat; a series of transmission actions will release the filter's locking mechanism, allowing it to be removed and replaced. This effectively reduces the pollution of the surrounding environment caused by welding fumes and significantly improves the practicality of the welding robot. Attached Figure Description

[0027] This utility model proposes an automatic welding robot for building steel components. Please refer to [reference needed]. Figures 1 to 6 Includes: fixed base 1;

[0028] A robot arm 101 is rotatably connected to the top surface of the fixed base 1; a robot crank 102 is rotatably connected to the upper part of the robot arm 101; a robot forearm 103 is rotatably connected to the front part of the robot crank 102; a robot wrist 104 is rotatably connected inside the robot forearm 103; a robot welding torch 105 is provided at the end of the robot wrist 104; two mounting seats 107 are symmetrically and fixedly connected to the bottom surface of the robot welding torch 105; a connecting rod 108 is rotatably connected inside each of the two mounting seats 107; a spatter shield 109 is fixedly connected to the end of each of the two connecting rods 108; and both spatter shields 109 are aligned with the position of the robot welding torch 105.

[0029] A control gear 110 is coaxially fixedly connected to the lower part of each of the two connecting rods 108; the two control gears 110 are respectively set in the two mounting seats 107; two electric push rods 106 are symmetrically bolted to the rear of the robot welding gun 105; a control rack 111 is fixedly connected to the end of the drive shaft of each of the two electric push rods 106; the two control racks 111 mesh with the two control gears 110 respectively.

[0030] Each of the two splash guards 109 has a set of smoke exhaust holes 112 at its rear; each of the two splash guards 109 has a smoke exhaust box 113 fixedly connected to its rear end face; the two smoke exhaust boxes 113 are respectively aligned with the positions of the two sets of smoke exhaust holes 112; each of the two smoke exhaust boxes 113 has an activated carbon filter screen 114 inserted inside; the two activated carbon filter screens 114 are respectively aligned with the positions of the two sets of smoke exhaust holes 112.

[0031] Each of the two smoke exhaust boxes 113 is fixedly connected to a set of fixed seats 115 on the outside; each of the two sets of fixed seats 115 is slidably connected to a set of guide slides 117; each of the two sets of guide slides 117 is fixedly connected to a locking block 116 on the inside; each of the two sets of guide slides 117 is fixedly connected to an auxiliary seat 119 at the end; each of the two sets of guide slides 117 is fixedly connected to a set of support springs 118 on the outside; and the ends of the two sets of support springs 118 are respectively fixedly connected to the inside of the two sets of fixed seats 115.

[0032] A connecting plate 120 is fixedly connected between the two control racks 111; an auxiliary push block 121 is fixedly connected to the front end face of the connecting plate 120; a mounting box 122 is provided at the lower part of the robot welding gun 105; a telescopic airbag 123 is provided inside the mounting box 122; the auxiliary push block 121 and the telescopic airbag 123 are aligned.

[0033] The specific usage and function of this embodiment: The welding robot is supported by the fixed base 1. Both electric push rods 106 in this application are electrically connected to the welding robot's control system. The control system controls the electric push rods 106, allowing the electric push rods 106 to be activated simultaneously with the welding robot's welding operation. Since the welding robot's control system is mature existing technology, it will not be described in detail here. The activation of the electric push rods 106 moves the control rack 111, which in turn rotates the control gear 110. The rotation of the control gear 110 then rotates the connecting rod 108. This rotation causes the anti-spatter cover 109 to close, covering the robot's welding torch 105 and the welding area. The inner side of the anti-spatter cover 109 is coated with a high-temperature resistant coating. Fumes generated during welding enter through the exhaust port 112. The flue gas entering the exhaust box 113 is filtered by the activated carbon filter 114, which filters out some of the harmful substances before discharging. The activated carbon filter 114 is limited by the locking block 116. When the activated carbon filter 114 needs to be replaced, simply pull the auxiliary seat 119, which moves the guide slide 117. The movement of the guide slide 117 moves the locking block 116. The movement of the locking block 116 releases the restriction on the activated carbon filter 114, allowing the activated carbon filter 114 to be removed and replaced. During the movement of the rack 111, the connecting plate 120 will move. When the splash shield 109 is closed, the auxiliary push block 121 moves away from the telescopic airbag 123, causing the telescopic airbag 123 to inhale. When the splash shield 109 is opened, the auxiliary push block 121 will squeeze the telescopic airbag 123.

[0035] Based on Example 1, please refer to Figure 2 and Figure 6 It includes: an air outlet frame 124, which is fixedly connected to the front end of the mounting box 122; the air outlet frame 124 is aligned with the position of the robot welding gun 105; the air inlet of the air outlet frame 124 is connected to the air outlet of the telescopic airbag 123.

[0036] The specific usage and function of this embodiment: After the telescopic airbag 123 is squeezed, gas will enter the air outlet frame 124 and be blown out along the air outlet frame 124 to clean the welding slag remaining on the robot welding gun 105.
