Detailed implementation manners

[0043] The following further describes the present application in detail with reference to the Figures 1 - 9 accompanying drawings.

[0044] Embodiment 1:

[0045] Embodiment 1 of the present application discloses a welding robot workstation. Refer to Figure 1 , a welding robot workstation includes an equipment platform 1 disposed on the ground, a welding platform 4 disposed on the surface of the equipment platform 1, two ground rails 2 disposed on two lengthwise sides of the equipment platform 1 in parallel, and two welding robots 3. The ground rails 2 and the welding robots 3 are arranged in a one-to-one correspondence. In this embodiment, both the equipment platform 1 and the ground rail 2 are fixedly connected to the ground through anchor plates and chemical bolts. The chemical bolts can be used to adjust the levelness of the equipment platform 1, thereby improving the stability of the working state of the equipment platform 1.

[0046] Refer to Figure 1 and Figure 2 , a plurality of abutting blocks 12 are welded to the surface of the equipment platform 1. A plurality of countersunk head grooves 41 for the abutting blocks 12 to abut against are formed in the bottom wall of the welding platform 4. After the abutting blocks 12 are inserted into the corresponding countersunk head grooves 41, they can abut against the inner wall of the countersunk head grooves 41, thereby positioning the welding platform 4; a plurality of positioning bolts 42 are disposed on the surface of the welding platform 4. The positioning bolts 42 pass through the welding platform 4 and are threadedly connected to the abutting blocks 12, so that the welding platform 4 can be locked with the equipment platform 1, and a detachable connection manner is formed between the welding platform 4 and the equipment platform 1. Thus, after the equipment platform 1 has been used for a certain period of time, the sparks generated during the welding process of the welding robot 3 will inevitably cause certain damage to the welding platform 4. The welding platform 4 can be replaced in time, thereby effectively improving the structural integrity and safety of the welding platform 4.

[0047] Reference Figure 1 and Figure 3 A plurality of mounting holes 11 are provided on the side wall of the equipment platform 1, and the mounting holes 11 can be used to install fixtures suitable for workpieces of different categories and sizes to be welded, so that the welding robot 3 workbench of the present application can weld workpieces of more different sizes and has high versatility.

[0048] Reference Figure 1 , a mounting plate 21 is slidably connected to the ground rail 2, and the welding robot 3 is connected to the surface of the corresponding mounting plate 21 by bolts, and can slide on the ground rail 2 following the mounting plate 21, so as to weld the workpiece. In this embodiment, the mounting plate 21 drives the helical gear on the mounting plate 21 to rotate through the rotation of the servo motor, so as to mesh with the rack of the ground rail 2 to realize the sliding of the mounting plate 21; the present application adopts two welding robots 3 for synchronous welding, which can effectively improve the welding efficiency compared with the traditional stand-alone welding workstation, and the provision of the ground rail 2 can effectively increase the working range of the robot, so that large-sized workpieces can be welded.

[0049] Reference Figure 1 and Figure 4 The surface of the mounting plate 21 is connected with a lubricating oil bag 24 by bolts. The lubricating oil bag 24 is used to lubricate the gears and racks inside the ground rail 2, thereby reducing the probability of the mounting plate 21 being difficult to move due to excessive friction between the gears and racks during the operation of the ground rail 2, making it difficult for the welding robot 3 to get stuck during the welding process, which can effectively improve the welding quality and welding stability. In this embodiment, the lubricating oil bag 24 is powered by a battery and does not require an external power supply. The oil supply is controlled by a single-chip microcomputer and can be adjusted by hours, days, and months, with high automation capabilities.

[0050] Reference Figure 1 A welding machine device 5 for providing welding wire and power to the welding robot 3 is provided at one end of the ground rail 2, and a gun cleaning device 6 for cleaning the welding gun of the welding robot 3 is provided at the end of the ground rail 2 away from the welding machine device 5. The gun cleaning device 6 can also be used for spraying anti-splash liquid and cutting wires. The welding machine device 5 and the gun cleaning device 6 are both electrically connected to the welding robot 3; a protective wiring harness 25 is provided on the side of each ground rail 2 away from the welding platform 4, and the protective wiring harness 25 is used to receive the cables of the ground rail 2 and the welding robot 3, thereby reducing the probability of the cables being damaged by electric sparks generated by welding during the welding process, improving the safety of the welding process and protecting the structural integrity of the welding robot 3 workstation.

[0051] Reference Figure 1 and Figure 5, mechanical limit sensors 23 are connected to both ends inside the ground rail 2 through bolts. The mechanical limit sensors 23 are electrically connected to the ground rail 2. When the welding robot 3 and the mounting plate 21 move beyond the stroke range, the mounting plate 21 will collide with the mechanical limit sensors 23. When the mechanical limit sensors 23 are squeezed, they will transmit signals to the ground rail 2, causing the servo motor of the ground rail 2 to lose power, thereby making an emergency stop for the welding robot 3 and the mounting plate 21, effectively improving the problem that the welding robot 3 derails and causes damage to the welding robot workstation and the staff, and enhancing the safety and stability during the welding process. In this embodiment, the mechanical limit sensors 23 are essentially pressure sensors.

[0052] Refer to Figure 1 and Figure 5 , baffles 22 are welded to both ends of the ground rail 2 in the length direction. The baffles 22 are used to block the welding robot 3 again after the mechanical limit sensors 23 fail, further reducing the probability of the welding robot 3 derailing and enhancing the safety of the welding robot 3 workstation of this application.

[0053] Refer to Figure 1 , a single-arm gantry crane 7 for loading or unloading the workpiece to be welded is provided on one side of the equipment platform 1. Setting the single-arm gantry crane 7 can effectively improve the problems of long time spent on manual loading and unloading and high labor intensity, and can effectively enhance the working efficiency of the welding process, with high practicability and convenience.

[0055] S1: Place the workpiece to be welded on the welding platform 4 through the single-arm gantry crane 7 and fix it with the corresponding fixture according to the specific shape of the workpiece;

[0056] S2: Teach and program the welding robot 3 and drive the welding robot 3 to weld the workpiece;

[0057] S3: After welding is completed, remove the fixture and transport the welded workpiece to the next processing point through the single-arm gantry crane 7, and repeat the above steps to perform welding processing on the workpiece.

[0058] The implementation principle of Embodiment 1 of this application for a welding robot workstation is as follows: Based on the traditional single-machine version of the welding robot 3 workstation, this application adds two ground rails 2 and one welding robot 3, enabling the welding robot 3 to slide along the ground rail 2. Two welding robots 3 perform synchronous welding on the workpiece, and its welding efficiency will be significantly improved; the welding robot 3 slides along the ground rail 2, which can effectively increase the working range of the welding robot 3. Moreover, several mounting holes 11 are opened on the side wall of the equipment platform 1, enabling the installation of special fixtures for workpieces to be welded with different types, sizes, and dimensions, effectively improving the versatility of the welding robot 3 workstation of this application and having high economic benefits. This application addresses the problems of low working efficiency, small working range, and poor versatility of the traditional single-machine version of the welding robot 3 workstation.
