[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets, including shearing, bending, riveting, splicing, and forming (such as car bodies). Currently, some sheet metal parts are irregularly shaped after processing, such as industrial control cabinets and server housings. They need to be sprayed to improve corrosion resistance. At the same time, spraying can also cover welding marks and enhance aesthetics.

[0013] Specific implementation of this utility model solution, such as Figure 1 As shown, the first drive assembly 2 and the second drive assembly 6 have completely identical structures. The first drive assembly 2 includes a first servo motor 21, a main gear 22, and a secondary gear 23. The first servo motor 21 is fixed inside the first mounting box 1; The main gear 22 is connected to the first servo motor 21, and the first rotating roller 3 is fixed with a secondary gear 23 that meshes with the main gear 22.

[0014] Specific implementation of this utility model solution, such as Figure 1 As shown, the horizontal position adjustment assembly 9 includes a positive and negative lead screw 91, a first slide rail 92, a turntable 93, and a rocker handle 94. The positive and negative lead screws 91 are rotatably mounted on the mounting platform 8 via bearings, and a set of clamping components 10 are threadedly connected to the two sections of the positive and negative lead screws 91 respectively. The first slide rail 92 is fixed on the mounting platform 8, and the first slide rail 92 slides in cooperation with the two sets of clamping components 10.

[0016] It should be noted that the first servo motor 21 in the first drive assembly 2 and the second servo motor in the second drive assembly 6 are both electrically connected to the controller, which is not shown in the figure.

[0017] The working process of this utility model is as follows: First, place the edge of the irregular part to be sprayed into the clamping area of ​​the two U-shaped rods 101 (adjust the distance between the two U-shaped rods 101 in advance by adjusting the horizontal position adjustment component 9 to adapt to irregular parts of different sizes (turning the rocker handle 94 to rotate the forward and reverse screws 91 can realize the synchronous movement of the two U-shaped rods 101 towards or away from each other). This can also improve the clamping stability during the subsequent orientation change of the irregular part). Then, by operating the two long screws 106 in sequence, the moving plate 105 can cooperate with the inner wall of the U-shaped rod 101 to clamp the edge area of ​​the irregular part. After clamping is completed, the controller first controls the first servo motor 21 in the first drive assembly 2 to operate, thereby realizing the horizontal rotation of the irregular part. Then, the six-degree-of-freedom robotic arm cooperates with the spray gun to spray the outside. After the outer coating is completed, the second servo motor in the second drive assembly 6 is controlled by the controller to achieve the vertical rotation of the irregular part. Then the inner area of ​​the irregular part can be exposed. At this time, the inner side can be coated with a six-degree-of-freedom robotic arm in conjunction with the spray gun (similarly, the operating trajectory of the six-degree-of-freedom robotic arm can be preset before the device is run). As a result, irregularly shaped parts can automatically rotate in both horizontal and vertical directions and flip over for multi-area spraying without the need for manual assistance, thus achieving better spraying results for irregularly shaped sheet metal parts. It should be noted that the edge areas of irregularly shaped parts cannot be painted because they are blocked by the clamping component 10. After the irregularly shaped parts are removed, the edges can be painted again.
