Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a base plate welding device. Background Technology

[0002] In the automotive parts processing industry, base plate welding usually requires multiple processes including pretreatment, welding, and inspection.

[0003] In existing technologies, these processes are often completed by independent equipment, resulting in lengthy and inefficient production lines, as well as numerous manual intervention steps that are prone to introducing errors. First, traditional automotive floor welding usually relies on manual operation or single-function welding equipment. Pre-treatment before welding and post-weld inspection need to be completed by multiple machines, resulting in a complicated process and a large footprint. Secondly, fixed operating tables lack flexibility and are difficult to adapt to the processing needs of automotive floor panels of different sizes or shapes, resulting in problems such as low efficiency, poor precision, and difficulty in ensuring consistency. Finally, the robotic arms of traditional automotive floor welding equipment have limited functionality and cannot integrate pretreatment, welding, and inspection into one unit, making it difficult to meet the high automation and high precision requirements of traditional automotive floor welding.

[0004] Therefore, a base plate welding device is provided to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a base plate welding device that solves the problems of low efficiency and unstable quality in automotive parts welding through automated, modular and high-precision design, while taking into account environmental protection and economy.

[0006] To achieve the above objectives, this utility model provides a base plate welding device, including an operating table and an operating unit. The operating unit includes a pre-treatment robotic arm, a welding robotic arm, and a detection robotic arm.

[0007] Preferably, multiple guide rails are provided between the support column and the welding robot arm, and fixing clamps are provided at the four corners of the fixing frame. Multiple pulleys are provided at the bottom of the fixing frame, and the number of pulleys is the same as the number of guide rails. The pulleys are arranged on the guide rails.

[0008] Preferably, the pretreatment robotic arm, the welding robotic arm, and the inspection robotic arm each include a transmission device and an operating head disposed on the transmission device. The transmission devices of the pretreatment robotic arm, the welding robotic arm, and the inspection robotic arm are the same, while the operating heads of the pretreatment robotic arm, the welding robotic arm, and the inspection robotic arm are different.

[0009] Preferably, the transmission device includes a base and a rotary joint disposed on the base. A first transmission arm is disposed on the rotary joint, and the rotary joint and the first transmission arm are movably connected via a rotary joint. A second transmission arm is disposed at the other end of the first transmission arm, and the second transmission arm is movably connected to the first transmission arm via a rotary joint. An operating head is disposed on the second transmission arm, and the operating head and the second transmission arm are movably connected via a rotary joint.

[0010] Preferably, the operating head of the pretreatment robotic arm includes a cleaning head and a drying head. The drying head is connected to an air filter via an air pipe, and the cleaning head is connected to a cleaning tank via a water pipe. The operating head of the welding robotic arm is configured as an electrode head, which is connected to a welding transformer via a cable.

[0018] Example like Figures 1-5As shown, this utility model provides a base plate welding device, including an operating table 1 and an operating unit 2. The operating unit 2 includes a pre-treatment robotic arm 201, a welding robotic arm 202, and a detection robotic arm 203. The pre-treatment robotic arm 201 and the detection robotic arm 203 are respectively arranged on both sides of the operating table 1, and the welding robotic arm 202 is arranged opposite to the operating table 1. The operating table 1 includes a support column 101 and a fixed frame 102. The support column 101 and the fixed frame 102 are movably connected by a rolling bearing 103.

[0019] Multiple guide rails 3 are provided between the support column 101 and the welding robot arm 202. Fixing clamps 4 are provided at the four corners of the fixed frame 102. Multiple pulleys 5 are provided at the bottom of the fixed frame 102. The number of pulleys 5 is the same as the number of guide rails 3. The pulleys 5 are set on the guide rails 3.

[0020] The pretreatment robotic arm 201, welding robotic arm 202, and inspection robotic arm 203 each include a transmission device 6 and an operating head 7 mounted on the transmission device 6. The transmission devices 6 of the pretreatment robotic arm 201, welding robotic arm 202, and inspection robotic arm 203 are the same, but the operating heads 7 of the pretreatment robotic arm 201, welding robotic arm 202, and inspection robotic arm 203 are different.

[0021] The transmission device 6 includes a base 601 and a rotary joint 602 disposed on the base 601. A first transmission arm 603 is disposed on the rotary joint 602. The rotary joint 602 and the first transmission arm 603 are movably connected through a rotary joint 604. A second transmission arm 605 is disposed at the other end of the first transmission arm 603. The second transmission arm 605 and the first transmission arm 603 are movably connected through a rotary joint 604. An operating head 7 is disposed on the second transmission arm 605. The operating head 7 and the second transmission arm 605 are movably connected through a rotary joint 604.

[0022] The operating head 7 of the pretreatment robotic arm 201 includes a cleaning head 8 and a drying head 9. The drying head 9 is connected to the air filter 11 via an air pipe 10, and the cleaning head 8 is connected to the cleaning tank 13 via a water pipe 12. The operating head 7 of the welding robotic arm 202 is set as an electrode head 14, and the electrode head 14 is connected to the welding transformer 16 via a cable 15. The operating head 7 of the inspection robotic arm 203 is set as an ultrasonic flaw detector 17.

[0023] The cleaning tank 13 is equipped with a cleaning solution 18, which is a mixture of a water-based solution and an organic solvent. The water-based solution includes deionized water and a surfactant, and the organic solvent is alcohol.

[0024] In practical application, the car floor is fixed on the mounting bracket 102 by the fixing clamp 4. The cleaning head 8 draws cleaning fluid 18 from the cleaning tank 13 through the water pipe 12 to clean the car floor. The mixed solution of water-based solution and organic solvent can remove stains or grease from the surface of the car floor. After cleaning, the drying head 9 draws gas from the air filter 11 through the air pipe 10 and blows out the filtered clean air to dry the car floor, ensuring that the welding surface is clean and free of residue. The current from the welding transformer 16 is transmitted to the electrode head 14 through the cable 15. The electrode head 14 is used to weld the car floor. During the welding process, the pulley 5 drives the fixed frame 102 to move on the guide rail 3 and achieves flexible rotation through the rolling bearing 103, which facilitates the precise positioning of the welding robot arm 202. At the same time, the rotary joint 602 can drive the transmission device 6 to rotate 360°. The first transmission arm 603, the second transmission arm 605 and the operating head 7 can all be rotated through the rotary joint 604 to provide multi-degree-of-freedom movement and ensure that the welding covers all areas that need to be processed. After welding is completed, the ultrasonic flaw detector 17 performs non-destructive testing on the car floor to check for defects such as porosity and cracks in the weld. After the test is completed, the fixing fixture 4 is adjusted, the car floor is removed, all devices are reset, and the process is ready for the next car floor.

[0025] Therefore, the base plate welding device of this utility model adopts the above-mentioned structure, which integrates the three processes of pretreatment, welding and inspection into one. The pretreatment robotic arm, welding robotic arm and inspection robotic arm work together to complete the process, which is fully automated, reduces human error and improves welding consistency and welding efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
