[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To address the issue that the spraying structure can only fully cover the front and back of the interior panels, but cannot spray the sides, and that paint runs when the interior panels are turned over before the paint is dry; please refer to... Figure 1-4 The present invention provides the following solution:

[0021] An adjustable spraying range automotive trim panel spraying device includes a spraying robotic arm 5, a gantry spraying frame 1, and a track base 2. The gantry spraying frame 1 is installed above the track base 2. The gantry spraying frame 1 includes a top frame 101 and a foot axle 102. The top frame 101 and the foot axle 102 are welded together. The bottom of the top frame 101 is provided with a hanging rail 4. The inside of the track base 2 is provided with a seat rail 3. The interior trim panel is vertically suspended on the surface of the hanger. The hanger is assembled with the bracket rail 201 on the surface of the track base 2. The hanger and the interior trim panel are moved by the bracket rail 201. During the movement, the spraying robotic arm 5 sprays the interior trim panel in four directions (up, down, left, and right). There is no need to flip the interior trim panel during the process, which avoids paint running.

[0022] There are four spraying robotic arms 5. Two of them are connected to the gantry spraying frame 1 via foot axles 102, and the other two are connected to the base rail 3 and the hanging rail 4 respectively. The top of the track base 2 is equipped with bracket rails 201 on both sides. The bracket rails 201 are connected to the track base 2 by screws. All four spraying robotic arms 5 can move horizontally, which can achieve a more uniform spraying effect.
