Description

Technical Field

[0001] The invention relates to the technical field of industrial robots, and in particular to a lifting device for an industrial robot. Background Art

[0002] As an important tool to improve production efficiency and reduce costs, industrial robots are increasingly used in a wide range of industries, including automobiles and their parts, electronics and electrical, mechanical processing, food, and chemicals. These robots are usually used to perform tasks such as welding, spraying, and handling. In industrial robot technology, the lifting device is a key component, which is responsible for lifting the robot's end effector (such as grippers, welding guns, etc.) to the required working position in order to perform various operating tasks. The design of the lifting device directly affects the flexibility, stability, and work efficiency of the industrial robot.

[0003] Although industrial robot technology has made significant progress and has been widely used in many industries, it still faces a series of challenges in actual application, especially when heavy objects need to be handled. Specifically, when the weight of the object exceeds the designed carrying capacity of the industrial robot, the robot arm may lose power or stability under the action of gravity, which may not only cause damage to the robot itself, but also pose a serious threat to surrounding workers and equipment. The existence of such safety hazards not only limits the application scope of industrial robots, but also increases the uncertainty and risk during operation.

[0004] However, many industrial robot systems currently do not fully consider this potential safety risk when designing, and therefore do not configure corresponding protective mechanisms to deal with the situation where objects are too heavy. As a result, in actual operation, once an overweight object is encountered, the robot may not be able to effectively deal with it, thus causing a safety accident. Therefore, a lifting device for an industrial robot is proposed to solve the above problem. Summary of the invention

[0051] Specifically, the design of the adapter 111 enables the manipulator 3 to be easily installed and disassembled, and is convenient for maintenance and replacement. The design of the slide bar not only provides additional support, but also ensures the stability of the manipulator 3 during the lifting process. The sliding connection between the slide bar and the lifting cylinder 11 enables the manipulator 3 to rise and fall smoothly, reducing the impact and vibration during the movement.

[0052] Furthermore, the manipulator 3 includes a mounting base, a robotic arm, a double cylinder and a pneumatic gripper, wherein the bottom of the mounting base is fixedly connected to the top of the adapter 111, the mounting base is a bracket for installing the robotic arm, and the robotic arm is connected by joints and connecting rods, and can realize arbitrary movement and turning within its range of motion; the double cylinder provides power for the movement of the manipulator 3 through pneumatic transmission, and the pneumatic gripper is connected to the robotic arm through a transmission shaft, which can transmit movement to the wrist for rotating, extending and bending the wrist or opening and closing the fingers.

[0053] Specifically, the design of the manipulator 3 takes full account of flexibility and functionality.

The pneumatic transmission mode of the double cylinder and the pneumatic gripper improves work efficiency and response speed.

[0054] Embodiment 3

[0055] In order to make the gantry adjust synchronously when the robot is lifting or rotating, such as Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the operating table 2 is designed with stainless steel, a support frame 23 is fixedly installed on the outer side of the lower end surface of the operating table 2, the bottom of the support frame 23 is fixedly connected to the upper end surface of the base 1, and a limit frame 21 is fixedly installed on the upper end surface of the operating table 2.

[0056] Specifically, the operating platform 2 is made of stainless steel, which not only has excellent corrosion resistance and durability, but is also easy to clean and maintain. The design of the support frame 23 enhances the stability of the operating platform 2, allowing it to withstand a larger load. The design of the limit frame 21 provides a clamping and fixing function for the gantry 5, ensuring the stability and safety of the gantry 5 in the slide 22.

[0057] Furthermore, the cross section of the slide groove 22 adopts a circular structure design, the depth of the slide groove 22 matches the thickness of the slide frame 51, and the inner wall of the slide groove 22 is provided with a hard chrome plating, which has high hardness and good wear resistance and is used to improve the wear resistance of the inner wall of the slide groove 22.

[0058] Specifically, the circular structure of the slide 22 not only facilitates the sliding and positioning of the slide 51, but also reduces friction and wear during the sliding process. The application of hard chrome plating further improves the wear resistance and service life of the inner wall of the slide 22, and reduces maintenance costs.

[0059] Furthermore, the slide 51 is designed with stainless steel material, and the slide 51 adopts a ring structure design. The slide 51 is clamped and installed on the inner side of the slide groove 22 by the limiting frame 21, and the outer diameter of the slide 51 matches the inner diameter of the slide groove 22.

[0060] Specifically, the slide 51 is made of stainless steel, which has excellent corrosion resistance and durability. The annular structure design allows the slide 51 to fit tightly inside the slide slot 22, improving the stability and accuracy of sliding. The outer diameter of the slide 51 matches the inner diameter of the slide slot 22, ensuring smooth sliding and non-interference.

The design of the inner rod 522 and the fixed frame 5221 enhances the stability and load-bearing capacity of the telescopic frame 52.

[0063] Embodiment 4

[0064] In order to ensure the stability and safety of the robot during the grasping action, Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the limiting assembly 4 includes a lifting cylinder 41, and a first rotating seat 42 is fixedly installed at the front end of the lifting cylinder 41. The front end of the lifting cylinder 41 is rotatably connected to the mechanical arm closest to the pneumatic gripper on the manipulator 3 through the first rotating seat 42, ensuring that the lifting cylinder 41 can flexibly rotate with the movement of the manipulator 3. The manipulator 3 is pushed up by the jacking cylinder 11 to rise and grab the heavy object, and the lifting cylinder 41 will also start accordingly. The lifting cylinder 41 provides the necessary supporting force through its telescopic function according to the movement trajectory and speed of the manipulator 3. This supporting force is dynamic and can be adjusted according to the weight of the heavy object and the force conditions of the manipulator 3, thereby ensuring that the manipulator 3 maintains stability when lifting the heavy object. A second rotating seat 43 is fixedly installed at the rear end of the lifting cylinder 41, and a walking frame 44 is rotatably installed at the rear end of the lifting cylinder 41 through the second rotating seat 43.

[0065] Specifically, the design of the limit assembly 4 takes safety and flexibility into full consideration. The lifting cylinder 41 is rotatably connected to the mechanical arm on the manipulator 3 through the first rotating seat 42, ensuring that the lifting cylinder 41 can flexibly rotate with the movement of the manipulator 3. The telescopic function of the lifting cylinder 41 provides the necessary supporting force, which is dynamic and can be adjusted according to the weight of the heavy object and the force applied to the manipulator 3, thereby ensuring that the manipulator 3 maintains stability when lifting heavy objects.

[0066] Furthermore, the traveling frame 44 is slidably mounted on the cross beam 53, and the traveling frame 44 includes a slide rail and a frame body for mounting the slide rail, wherein the slide rail is mounted inside the frame body and matches and slidably cooperates with the cross beam 53, and the traveling frame 44 is fixedly connected to the second rotating seat 43 through the frame body.

[0067] Specifically, the design of the traveling frame 44 enables the limit assembly 4 to slide on the crossbeam 53, so as to be fine-tuned according to actual needs. The design of the slide rail and the frame body enhances the stability and load-bearing capacity of the traveling frame 44. The traveling frame 44 is fixedly connected to the second rotating seat 43 through the frame body, ensuring that the connection between the lifting cylinder 41 and the traveling frame 44 is firm and reliable. This design not only improves the flexibility and adaptability of the limit assembly 4, but also enhances the safety and stability of the entire lifting device.

[0068] When the present invention is used, ensure that the base 1 is firmly installed in the desired position and fixed by the mounting bolts. The operating table 2 is also firmly connected to the base 1 through the support frame 23. The slide 51 of the gantry 5 is placed in the slide groove 22 of the operating table 2 and is clamped and fixed by the limit frame 21. As needed, the height of the telescopic frame 52 is adjusted by adjusting the cylinder 54 so that the crossbeam 53 is in a suitable position. This step can be adjusted according to the actual working height and the operating range of the manipulator 3. The lifting cylinder 41 of the limit assembly 4 is rotatably connected to the mechanical arm on the manipulator 3 through the first rotating seat 42, and is connected to the walking frame 44 through the second rotating seat 43. In this way, when the weight is too heavy, the lifting cylinder 41 can provide an upward supporting force to help share the pressure borne by the manipulator 3 and the lifting cylinder 11.

[0069] When it is necessary to lift a heavy object, start the lifting cylinder 11 to push the adapter 111 and the manipulator 3 up. Under pneumatic transmission, the manipulator 3 can flexibly adjust the position and posture of the pneumatic gripper through the synergy of the mechanical arm and the double cylinder. When the manipulator 3 rises to the specified position, the pneumatic gripper closes to grab the heavy object. During the entire lifting and moving process, the limit assembly 4 plays a key safety protection role. When the heavy object is too heavy and causes the manipulator 3 or the lifting cylinder 11 to be subjected to excessive pressure, the lifting cylinder 41 can reduce the pressure through the additional support force it provides to prevent the manipulator 3 from losing stability or being damaged. At the same time, the sliding function of the walking frame 44 also allows fine-tuning of the heavy object when necessary to maintain its stability and safety.
