[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] Combination Figure 1 to Figure 2 As shown, this embodiment provides a robotic arm construction work platform, including a support frame 1, a robotic arm work platform 2 slidably connected to the support frame 1, a linear drive mechanism for driving the robotic arm work platform 2 to slide back and forth along the length direction of the support frame 1, a robotic arm assembly 3 rotatably mounted on the robotic arm work platform 2, a rotating drive mechanism 4 for driving the robotic arm assembly 3 to rotate around the height direction of the support frame 1, and a positioning mechanism 5 for fastening the robotic arm assembly 3 to the robotic arm work platform 2; with this structural design, the forward and backward movement and rotation of the robotic arm assembly 3 can be conveniently and flexibly realized, thereby satisfying the multi-axis motion of the robotic arm assembly 3.

[0020] Furthermore, in order to further enhance the multi-axis movement of the robotic arm assembly 3 and increase the lifting force and stability during upward swinging, the robotic arm assembly 3 in this embodiment includes a robotic arm rotatably connected to the rotary drive mechanism 4, an arc-shaped rack 31 coordinated with the positioning mechanism 5, and a swing drive mechanism for driving the robotic arm to swing up and down along the arc-shaped rack 31.

[0021] Preferably, the swing drive mechanism includes a swing reducer 321 mounted at one end of the robotic arm, a swing motor 322 connected to the power input end of the swing reducer 321, and a gear 323 arranged at the power output end of the swing reducer 321, and the gear 323 is meshed with the arc rack 31.

[0022] Combination Figure 1 and Figure 2 As shown, arc-shaped racks 31 are arranged in parallel and at intervals on both sides of the swing reducer 321, and the upper ends of the two arc-shaped racks 31 are connected as a whole through a connecting plate 324 to increase the stability of the two arc-shaped racks 31 after installation. Then, the arc-shaped racks 31 are meshed with the gears 323 arranged on the power output ends on both sides of the swing reducer 321 through the tooth grooves on the outer arc surface.

[0023] More specifically, the rotary drive mechanism 4 in this embodiment includes a rotary reducer 41 mounted on the robot arm workbench 2, a rotary motor connected to the power input end of the rotary reducer 41, and a bearing seat 42 connected to the power output end of the rotary reducer 41, the bearing seat 42 is rotatably connected to the robot arm, and further specifically, the robot arm includes a rotating shaft 431 rotatably connected to the bearing seat 42, two arm rods 332 mounted in parallel and spaced apart at both ends of the rotating shaft 331, and a connecting seat 333 arranged at the same end of the two arm rods 332.

[0024] The robotic arm assembly 3 adopts the above-mentioned structural design. Since the two arm rods 332 in the robotic arm assembly 3 are rotatably connected to the bearing seat 42 in the rotating drive mechanism 4 through the rotating shaft 331, the two arm rods 332 can rotate around the rotating shaft 331 on the bearing seat 42 in the rotating drive mechanism 4 under the driving action of the swing motor 322, and with the help of the setting of the arc-shaped rack 31, the load-bearing capacity of the two arm rods 332 is effectively increased, which greatly improves the lifting force of the two arm rods 332. Compared with the multi-axis robotic arm of traditional structure, the ability to lift heavy objects is greatly improved when the torque of the swing motor 322 remains unchanged.

[0025] Furthermore, in order to enable the above-mentioned robot arm to maintain good stability when lifting heavy objects, the positioning mechanism 5 includes a pressure plate 51 horizontally fastened to the lower end of the arc-shaped rack 31, and an electromagnet 52 disposed at both ends of the pressure plate 51 and adsorbed to the robot arm workbench 2. When the robot arm rotates, the electromagnet 52 separates from the robot arm workbench 2. When the robot arm reaches a predetermined position, the lower end of the arc-shaped rack 31 can be firmly fixed to the robot arm workbench 2 through the electromagnet 52, thereby providing stable and reliable support for the robot arm when carrying heavy objects.

[0026] Further, as a preference, the support frame 1 in this embodiment includes a fixed seat 11, a frame body 12 fastened to the fixed seat 11, and a slide rail 13 arranged along the length direction of the frame body 12, and the robotic arm workbench 2 is slidably connected to the slide rail 13 via a slider.

[0027] Furthermore, in order to drive the robot arm work platform 2 to slide back and forth along the length direction of the frame 12, the linear drive mechanism in this embodiment includes a screw rod 61 arranged along the length direction of the frame 12, a sliding seat threadedly connected to the screw rod 61, and a drive motor 62 arranged at one end of the screw rod 61 close to the fixed seat 11, and the drive motor 62 is connected to the screw rod 61 through a coupling. As a further preferred embodiment, the linear drive mechanism is located below the robot arm work platform 2, and the sliding seat is fastened to the lower bottom surface of the robot arm work platform 2.

[0028] The robotic arm construction work platform adopting the above-mentioned structural design can not only effectively meet the multi-axis movement of the robotic arm, but also can effectively improve the lifting force of the robotic arm through the engagement between the arc rack 31 and the swing reducer 321, and the limitation of the arc rack 31 by the positioning mechanism 5, and maintain the stability of the robotic arm during continuous lifting, and can also effectively reduce the power consumption of the motor.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
