Abstract
Description
Technical Field
[0001] The utility model relates to the field of welding equipment, and particularly relates to a flexible front panel stud planting workstation. Background Art
[0002] People usually divide the technical development of stud welding into three main stages. The first stage was from 1918 to around 1975. During this period, stud welding technology emerged from scratch and gradually became a mature welding process method, and began to be gradually applied to some industrial fields. The second stage was approximately ten years from the 1970s to the 1980s. The United States, Australia, and Germany successively launched automatic stud welding machines in manual, semi-automatic, and full-automatic modes, which shortened the welding time and reduced the time cost. The third stage was approximately ten years from 1985 to 1995. Stud welding technology began to be combined with robot technology and computer technology, and a variety of sensors were applied to robots and automatic welding machines, which were controlled by a computer and equipped with a high-quality monitoring system. The current implementation method in the industry: Stud welding technology is a welding method that welds studs or stud-like objects (which can be rods, tubes, or narrow strips) on plates, the arc surface of round tubes, or other surfaces. The welding methods mainly used for the connection of stud-type fasteners include arc stud welding, electric energy storage stud welding, etc. In the traditional design in the industry, manual welding is used. The main problems are that when stud planting requires bending over for operation, each stud weld needs to be designed with a sleeve, and the fixture mechanism is complex, making it difficult to achieve manual operation shared by multiple vehicle models, and the quality consistency is poor, and the qualified rate is low. In addition, there is a risk of scratching personnel during the flipping process of the fixture. So-called stud welding is a method of welding metal studs or other similar fasteners to workpieces. Currently, most of the stud welding equipment used in the automotive field is short-cycle stud welding. The main distribution points of stud welding are areas such as the front partition, floor, and roof that need to be arranged with interior trim or plastic parts, etc. The main factors affecting the stud welding effect include material factors, equipment factors, welding pressure, working voltage, surface smoothness of the welding material, flatness of the welding surface, etc. Therefore, it is still difficult to achieve manual operation shared by multiple vehicle models, and the quality consistency is poor, the qualified rate is low, and there is a risk of scratching personnel during the flipping process of the fixture. Content of the Utility Model
[0003] In view of the above problems, the purpose of the utility model is to provide a personalized front panel stud planting workstation with high finished product rate, high processing efficiency, and production safety.
[0004] To achieve the above object, a flexible front panel studding workstation provided by the utility model is characterized in that it includes a first station, a second station provided on one side of the first station, a third station provided on one side of the second station, a fourth station provided on one side of the third station, a first gripper placement rack and a first studding robot provided on one side of the first station, a second gripper placement rack and a second studding robot provided on one side of the second station, a welding robot provided on one side of the second gripper placement rack, a third gripper placement rack and a handling robot provided on one side of the third station, a first servo table provided on one side of the handling robot, and a second servo table provided on one side of the fourth station.
[0005] In some embodiments, the first studding robot, the second studding robot, and the handling robot are all FANUC robots.
[0006] The beneficial effects of the utility model are to improve the yield, have high processing efficiency, and ensure production safety. Since the improved structure uses a robot to grab the studding gun instead of manual studding, only corresponding mounting holes need to be designed on the fixture, and the studding machine is equipped with a quick-change mounting plate, thus achieving the effects of improving the yield, having high processing efficiency, and ensuring production safety. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 is a schematic structural diagram of the utility model;
[0008] Figure 2 is Figure 1 a schematic structural diagram from another perspective. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0009] The utility model will be further described in detail below with reference to the drawings.
[0010] As Figure 1-2 shown, a flexible front panel studding workstation includes a first station 1, a second station 2 provided on one side of the first station 1, a third station 3 provided on one side of the second station 2, a fourth station 4 provided on one side of the third station 3, a first gripper placement rack 5 and a first studding robot 6 provided on one side of the first station 1, a second gripper placement rack and a second studding robot 8 provided on one side of the second station 2, a welding robot 10 provided on one side of the second gripper placement rack, a third gripper placement rack and a handling robot 7 provided on one side of the third station 3, a first servo table 9 provided on one side of the handling robot 7, and a second servo table 9 provided on one side of the fourth station 4. The first studding robot 6, the second studding robot 8, and the handling robot 7 are all FANUC robots.
[0011] When applied, the FANUC robot features flexible movement, high speed, and high precision. It has particularly high requirements for the accuracy of the motion trajectory. According to the accuracy requirements of the front apron stud welding and spot welding, the FANUC R2000I C / 210F robot is adopted, with a payload of 210 kg, a maximum motion radius of 2655 mm, and a repeat positioning accuracy of ±0.05 mm. It is a hollow wrist joint type structure, with a light mechanism, a large motion range, and high stability. The stud welder selected is the PIDS stud welder of Shenzhen Hongbai Technology. The PIDS stud welding system is a product developed and designed by Shenzhen Hongbai Technology Industry Co., Ltd. to meet the new requirements and characteristics of automotive body stud welding. It mainly targets the changes in automotive manufacturing materials and processes, such as: stud welding of aluminum bodies, stud welding of high-strength materials, stud welding of over-sized original stud diameters / workpieces with thin or thick plates, and stud welding using a robot welding system. It is designed for the situation that many domestic and foreign stud welding and the original stud welding systems in the industry cannot well solve these problems. The flexible switching mechanical structure of the vehicle uses a robot to grab the stud gun instead of manual studding. The fixture of the studding machine is interchanged using a turntable, and the motor uses the Fanuc ai s22 model for robot control, achieving 360° axial displacement to solve the problem of studding on both sides of the workpiece. For future vehicle model switching, only the corresponding mounting holes need to be designed on the fixture. The studding machine is equipped with a quick-change mounting plate, and if the type of stud changes, the gun can be directly replaced.
[0012] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the utility model.
