Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial robot technology, specifically a quick-change system for welding torches and grippers. Background Technology
[0002] Industrial robots are automated, programmable, multi-jointed mechanical devices widely used in manufacturing. They can perform various complex tasks (such as handling, welding, painting, assembly, etc.) to improve efficiency, precision, and production safety. Industrial robots need to constantly change their working tools, such as switching between welding torches and grippers.
[0003] In the prior art, Chinese Patent Application No. CN202122830512.9 discloses a switchable welding torch gripper structure, including a frame, a gripper placement platform on the frame, a positioning mechanism on the gripper placement platform, a clamping mechanism on one side of the positioning mechanism, a welding torch on one side of the clamping mechanism, and a robot tool quick-change device on the positioning mechanism. This enables automatic positioning, clamping, and welding of a workpiece on a single machine, avoiding the need for other workstations or mechanisms to achieve workpiece positioning and clamping. It not only reduces the equipment's footprint and the cost of purchasing other mechanisms but also achieves functional versatility, making it more convenient to use and more flexible in operation. It effectively solves the problem that current welding machines cannot perform positioning, clamping, and welding operations on a single machine, resulting in their limited application.
[0004] Based on the above information, it can be seen that robots in the prior art can be used for welding operations. However, in actual use, robots generally need to change their end-effector tools. The prior art cannot automatically change the end-effector tools, so the robot cannot perform smooth processing operations on a workpiece. Summary of the Invention
[0005] The purpose of this invention is to provide a quick-change system for welding torches and grippers to solve the problem of robot operation tools being unable to be switched as mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-change system for welding torch and gripper, comprising a work platform raised above the ground, an industrial operating robot installed at the middle position of the upper surface of the work platform, a gripper placement frame and a welding torch placement frame respectively fixedly installed on the front and rear sides of the upper surface of the work platform, a gripper assembly placed above the gripper placement frame, and a welding torch assembly placed above the welding torch placement frame, a clamping cylinder docking station fixedly installed on the left side of the upper surface of the work platform, and a torch repair assembly corresponding to the welding torch placement frame fixedly installed on the rear side of the upper surface of the work platform, and a protective cover structure provided on the outside of the torch repair assembly.
[0007] Preferably, the robot end effector is equipped with a quick-change disc R side.
[0008] Preferably, the upper plate of the clamping cylinder docking station is fitted with equally spaced spare clamping cylinders, and the upper plate of the clamping cylinder docking station is driven to rotate by an internal motor.
[0009] Preferably, the upper surface of the gripper assembly is fixedly installed with the first quick-change disc T side that cooperates with the quick-change disc R side, and mechanical grippers are installed at the lower ends of the four corners of the gripper assembly.
[0010] Preferably, a gripper clamping cylinder is installed at the lower end of the gripper assembly, and the gripper clamping cylinder forms a quick-release structure with the gripper assembly through a quick-change clamping cylinder disc, and the gripper clamping cylinder is divided into two types: pneumatically driven and mechanically driven.
[0011] Preferably, the upper surface of the welding torch assembly is equipped with a second quick-change disc T side that mates with the quick-change disc R side.
[0012] Preferably, a protective mechanism is installed on the upper rear surface of the welding torch holder.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the quick-change system for the welding torch and gripper adopts a novel structural design, the specific details of which are as follows: 1. The quick-change disc facilitates tool replacement and forms an energy medium channel through modular cooperation, enabling a single robot to operate more end fixtures and perform multiple work steps. The robot's working end is equipped with the quick-change disc R side. The quick-change disc R side, in cooperation with the first quick-change disc T side of the gripper assembly and the second quick-change disc T side of the welding torch assembly, achieves the purpose of rapid switching. Furthermore, the quick-change disc allows for rapid replacement of gripper fixtures, satisfying the gripping needs of multiple stations and parts with different characteristics. The quick-release structure between the gripper clamping cylinder and the clamping cylinder quick-change disc, combined with the spare clamping cylinder at the clamping cylinder docking station, achieves the purpose of changing gripper fixtures.
[0014] 2. Quick-change tray protection mechanism to prevent airborne particles from falling on module pins and causing short circuits or open circuits. Rotate the protection mechanism to a horizontal position to shield the welding torch assembly for protection. Furthermore, this system has a wide range of applications. It can be used for a single robot to perform multiple different work steps, or for multiple robots to work together to perform multiple combined work steps in the same work unit.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: a quick-change system for welding torch and gripper, including a work platform 1 raised above the ground, an industrial operation robot 2 installed in the middle of the upper surface of the work platform 1, a gripper placement frame 4 and a welding torch placement frame 5 respectively fixedly installed on the front and rear sides of the upper surface of the work platform 1, a gripper assembly 401 placed above the gripper placement frame 4, and a welding torch assembly 501 placed above the welding torch placement frame 5, a clamping cylinder docking station 3 fixedly installed on the left side of the upper surface of the work platform 1, and a torch repair assembly 6 corresponding to the welding torch placement frame 5 fixedly installed on the rear side of the upper surface of the work platform 1, and a protective cover structure is provided on the outside of the torch repair assembly 6.
[0019] The robot 2 has a quick-change disc R side 201 installed at its end. The upper plate of the clamping cylinder docking station 3 is fitted with spare clamping cylinders 301 that are evenly distributed. The upper plate of the clamping cylinder docking station 3 is driven to rotate by an internal motor. The upper surface of the gripper assembly 401 is fixedly installed with a first quick-change disc T side 402 that cooperates with the quick-change disc R side 201. Mechanical grippers are installed at the lower ends of the four corners of the gripper assembly 401. The gripper clamping cylinder 403 is installed at the lower end of the gripper assembly 401. The gripper clamping cylinder 403 forms a quick-connect structure with the gripper assembly 401 through the clamping cylinder quick-change disc 404. The gripper clamping cylinder 403 is divided into two types: pneumatic drive and mechanical drive. The upper surface of the welding torch assembly 501 is equipped with a second quick-change disc T side 502 that cooperates with the quick-change disc R side 201. The upper surface of the rear end of the welding torch placement frame 5 is equipped with a protective mechanism 503.
[0020] When robot 2 is working, it first rotates the quick-change disc R side 201 at the end of the end to the position corresponding to the gripper placement frame 4. Then, it moves the quick-change disc R side 201 to a position that mates with the first quick-change disc T side 402 on the upper surface of the gripper assembly 401, achieving rapid installation. Afterward, robot 2 rotates the gripper assembly 401 to the workpiece position and activates the gripper clamping cylinder 403 to grip the workpiece. When dealing with different types of workpieces, robot 2 rotates the gripper assembly 401 to the clamping cylinder resting station 3 position (the disc above the clamping cylinder resting station 3 is driven by a motor to rotate, automatically rotating the spare clamping cylinder 301 that needs to be replaced to a ready position). The quick-release structure between the spare clamping cylinder 301 and the gripper assembly 401 is used to replace the clamping cylinder, thereby enabling the handling of different workpieces. The workpiece is clamped and then placed into the processing position by robot 2. Robot 2 then rotates to the gripper placement frame 4 and places the gripper assembly 401 onto it. Next, robot 2 rotates to the welding torch placement frame 5. Here, the welding torch assembly 501 is installed onto robot 2 by using the cooperation between the quick change plate R side 201 and the second quick change plate T side 502 (when the welding torch assembly 501 is being installed, the protective mechanism 503 above the welding torch placement frame 5 rotates to a horizontal position to block it, thus protecting the welding torch assembly 501). Then, robot 2 operates the welding torch assembly 501 to perform welding operations on the workpiece. When the welding torch is deformed, robot 2 moves the welding torch assembly 501 to the repair torch assembly 6 for repair.
