Description

Technical Field

[0001] This utility model relates to the field of automotive body sheet metal forming technology, and in particular to a sheet metal corner edge wrapping device. Background Technology

[0002] Body edge binding is a key process in automobile manufacturing. Due to the need for flexible production, robotic edge binding has been widely used. Existing robotic edge binding technology involves a roller contacting the sheet metal outer panel and applying radial pressure through roller rotation, causing deformation of the outer panel. Robotic edge binding technology has the advantages of simple structure and high flexibility. However, for edge binding at sheet metal corners, because the roller and sheet metal are in near-line contact, the force direction changes drastically in the corner area. Furthermore, since the roller is mounted at the end of the robot, positioning accuracy fluctuates, making it difficult to obtain the optimal process position. This results in surface deformation of the sheet metal after edge binding, such as surface indentations and uneven corner radius, among other appearance defects.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0020] like Figures 1-3 As shown, this embodiment of the utility model provides a sheet metal corner binding device, including a binding body 1 and a guide module 2. The bottom of the binding body 1 is provided with a guide wheel 11. The side of the binding body 1 is provided with a corner pressing module 12, the shape of which corresponds to the shape of the sheet metal corner. The guide module 2 is provided with a guide surface 21, and the guide wheel 11 is located on the guide surface 21 and rolls along the guide surface 21.

[0021] like Figure 2 As shown in the figure, the sheet metal corner binding device provided in this embodiment can be installed at the end of a robot. The robot is connected to a remote PLC and is equipped with a corner pressing module 12 corresponding to the shape of the sheet metal corner. When binding the sheet metal corner, force can be applied to all positions of the sheet metal corner simultaneously, ensuring good and uniform force distribution in all areas of the corner, reducing corner binding deformation and improving appearance quality. In addition, since the bottom guide wheel 11 is located on the guide surface 21 when the binding body 1 moves and performs binding operations, the movement trajectory of the binding body 1 can be controlled, reducing the positioning accuracy fluctuation of the robot end and improving the binding accuracy and stability. Furthermore, as shown by the arrow in the figure, the guide wheel 11 can slide and rotate on the guide surface 21, restricting the degree of freedom of the corner pressing module 12. This ensures the accuracy of the corner binding cut angle and the stability of the binding force applied to the sheet metal, so that the sheet metal edge receives uniform force during the binding process, thereby obtaining better sheet metal binding quality.

[0022] To improve the flexibility of the equipment and adapt to sheet metal corners of different shapes, such as Figure 3 As shown, in one embodiment of this utility model, the side of the edging body 1 is provided with a mounting block 13, the bottom surface of the mounting block 13 is stepped, forming a plurality of mounting bottom surfaces 131. There are multiple corner pressing modules 12, which are disposed on the corresponding mounting bottom surfaces 131, and each corner pressing module 12 is detachably connected to the mounting bottom surface 131 for easy replacement.

[0023] To further improve the flexibility of the equipment and adapt to sheet metal corners of different shapes, such as Figure 3 As shown, in one embodiment of this utility model, the side of the edging body 1 is provided with a plurality of mounting blocks 13, which are distributed circumferentially along the edging body 1. Different corner pressing modules 12 can be switched by rotating the edging body 1. Furthermore, for convenient switching, a rotating ring 14 is provided in the middle of the edging body 1, and the mounting blocks 13 are located on the side of the rotating ring 14. In this way, different corner pressing modules 12 can be switched by simply rotating the rotating ring 14 without rotating the edging body 1.

[0024] like Figure 3 As shown, in one embodiment of the present invention, the bottom surface of the corner pressing module 12 is provided with an upwardly recessed notch 121, so that the bottom surface of the corner pressing module 12 is U-shaped or V-shaped.

[0025] To facilitate connection with robots, such as Figures 1-3 As shown, in one embodiment of this utility model, the top of the edging body 1 is provided with a robot connecting flange 15.

[0026] like Figures 1-2As shown, in one embodiment of this utility model, the sheet metal corner edge-wrapping device further includes a rolling die 3 for placing the sheet metal. Specifically, the rolling die 3 is made of alloy ductile iron with a hardness of HRC55 or higher, and its top surface matches the profile of the sheet metal outer panel. Preferably, as... Figures 4-5 As shown, the top surface of the rolled edge film 3 is parallel to the guide surface 21 to obtain the optimal cutting force angle (arrow direction).

[0027] To facilitate the positioning of sheet metal, such as Figure 1 , Figure 2 As shown, in one embodiment of this utility model, an inner panel positioning device 31 is provided above the hemming film 3 for positioning the inner panel 4 of the sheet metal. An outer panel bottom positioning device 32 is provided inside the hemming film 3 for fixing the vertical position of the outer panel 5 of the sheet metal. Further, an outer panel side positioning device 33 is provided on the outer side of the hemming film 3 for fixing the horizontal position of the outer panel 5 of the sheet metal.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
