[0002] In the painting process of automotive panels, the three-coat process for curved panels is particularly prone to paint sagging due to gravity. Because of the geometric characteristics of curved surfaces, paint tends to sag at edges or points of curvature change after spraying, severely affecting coating uniformity and appearance quality. Furthermore, the rigid support structure of ordinary fixtures is difficult to fit tightly against curved panels, and the contact points or positioning structures of the fixtures may obstruct the spraying area, leading to localized missed areas or uneven coating, further impacting appearance quality. Therefore, there is an urgent need for an anti-sagging spraying fixture for the three-coat process of automotive panels. Utility Model Content

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a base 1 and positioning rods 13, and four positioning rods 13 are provided on the top of the base 1;

[0028] It also includes:

[0029] There are four electric telescopic rods 3, all of which are fixedly installed on the upper part of the base 1. The upper end of the electric telescopic rod 3 is movably connected to the pneumatic suction cup 2 through the joint bearing. Reinforcing ribs 12 are fixedly installed on the four sides of the electric telescopic rod 3, and the reinforcing ribs 12 are fixedly installed on the upper part of the base 1. The reinforcing ribs 12 can improve the connection strength between the electric telescopic rod 3 and the base 1, making the panel more stable.

[0030] Telescopic cover 4 is fixedly installed on the upper part of the base 1 at the outer position of the four No. 1 electric telescopic rods 3. A connecting rod 5 is fixedly installed on the side wall of the output rod of the No. 1 electric telescopic rod 3, and one end of the connecting rod 5 is connected to the telescopic cover 4.

[0031] Hot air blower 6 is fixedly installed on the upper part of the base 1 at the inner side of the telescopic cover 4. The upper part of the base 1 is provided with sliding grooves 7 around the telescopic cover 4. The sliding grooves 7 are provided with positioning adjustment mechanisms 8 connected to positioning rods 13. The base 1 is provided with flipping storage mechanisms 9 connected to positioning adjustment mechanisms 8.

[0032] The positioning adjustment mechanism 8 includes:

[0033] The slider 8-1 is slidably disposed in the slide groove 7. A support rod 8-2 is fixedly disposed on the slider 8-1. A positioning rod 13 is disposed in the storage groove opened on the support rod 8-2. A baffle plate 10 is fixedly sleeved on the support rod 8-2 and is disposed below the storage groove. The baffle plate 10 can form a baffle above the slide groove 7 to prevent paint from being sprayed into the slide groove 7 during the spraying process and causing the slider 8-1 to get stuck.

[0034] An adjusting screw 8-3 is inserted into a slide groove 7 via a bearing. A slider 8-1 is mounted on the adjusting screw 8-3 via a thread. One end of the adjusting screw 8-3 passes through the base 1 and is fixedly fitted with an adjusting handle 8-4. When the adjusting screw 8-3 rotates, the slider 8-1 can be moved to change the position of the support rod 8-2 and the positioning rod 13, thus enabling the adaptation and positioning of panels of different sizes and specifications.

[0035] The flip-up storage mechanism 9 includes:

[0036] The lifting rods 9-1 consist of eight rods, which are movably inserted into the side walls of the four support rods 8-2. A lifting frame 9-2 is fixedly installed at the upper end of the lifting rods 9-1. A rack 9-3 is fixedly installed on the side wall of the lifting frame 9-2. A spring 9-4 connected to the lifting frame 9-2 is fixedly installed inside the side wall of the support rod 8-2.

[0037] Rotating rod 9-5, there are four rotating rods 9-5, which are fixedly inserted on four positioning rods 13 respectively. The two ends of the rotating rod 9-5 are respectively inserted into the two side walls of the support rod 8-2 through bearings and fixedly sleeved with gears 9-6. The gears 9-6 are meshed with the rack 9-3.

[0038] The second electric telescopic rod 9-7 is fixedly installed inside the base 1. A movable frame 9-8 is fixedly installed at the upper end of the second electric telescopic rod 9-7 and is movably installed inside the base 1. Several guide rods 11 are fixedly installed inside the base 1 and movably pass through the movable frame 9-8. The guide rods 11 guide the vertical movement of the movable frame 9-8, thereby effectively improving its stability. The lower end of the lifting rod 9-1 passes through the slider 8-1 and is movably abutting against the movable frame 9-8. The flipping and storage mechanism 9 enables the synchronous flipping of the four positioning rods 13. After the panel is accurately positioned using the positioning rods 13, the positioning rods 13 can be flipped into the storage slot for storage, preventing obstruction of the panel's coating.

[0039] When using this utility model, the height of the pneumatic suction cups 2 can be adjusted using the first electric telescopic rod 3 according to the curvature of the panel to be placed. Then, the panel is placed on the four pneumatic suction cups 2. The four positioning rods 13 can limit the placement position of the panel, thereby positioning the panel. Using the joint bearing, the four pneumatic suction cups 2 can be tilted to fit well against the bottom of the panel. Then, the pneumatic suction cups 2 are activated to suction and fix the panel. After that, the second electric telescopic rod 9-7 is shortened. The second electric telescopic rod 9-7 drives the movable frame 9-8 to move downward. Under the downward pushing force of the spring 9-4 on the lifting frame 9-2, the lifting frame 9-2 drives the rack 9-3 and the lifting rod 9-1 to move downward. At this time, the gear 9-6 will... Rotating rod 9-5 causes positioning rod 13 to flip downwards, detaching it from the edge of the panel and retracting it into the storage compartment. This prevents positioning rod 13 from obstructing the panel's coating. After the panel's upper surface is coated, hot air blower 6 can be activated. Hot air blower 6 blows hot air from the bottom of the panel to moderately heat it, accelerating local solvent evaporation and reducing dripping. Simultaneously, the telescopic cover 4 reduces heat loss and allows for more precise control of the panel's heating temperature. If the position of positioning rod 13 needs to be adjusted according to the panel's size, adjusting handle 8-4 can be rotated. Adjusting handle 8-4 rotates adjusting screw 8-3, causing slider 8-1 to move support rod 8-2, thereby changing the position of positioning rod 13.

[0040] Compared with the prior art, the beneficial effects of this utility model are:

[0041] With four electric telescopic rods 3 with joint bearings and pneumatic suction cups 2, the height and angle can be flexibly adjusted to fit closely to the bottom of the car panel with different curvatures, achieving self-adaptive fixation and avoiding stress concentration or panel deformation caused by rigid support.

[0042] With the cooperation of the flipping and storage mechanism 9, after the panel is positioned, the driving positioning rod 13 can be automatically flipped and stored in the storage slot of the support rod 8-2, so as to avoid the positioning rod 13 from blocking the spraying path of the panel.

[0043] With the cooperation of hot air blower 6 and telescopic cover 4, the non-appearance surface of the bottom of the panel can be heated. The heat conduction of the metal panel accelerates the evaporation of the wet film solvent, quickly establishes a high viscosity surface layer, and effectively suppresses the sagging phenomenon at the edge of the curved panel and the curvature change area.

[0044] With the cooperation of the positioning adjustment mechanism 8, the positions of the support rod 8-2 and the positioning rod 13 can be changed, enabling the adaptation and positioning of panels of different sizes and specifications.

[0045] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
