[0027] 1. In the present invention, by setting up an air curtain spraying assembly, through the precise cooperation of the driving motor and the movable screw, the first screw seat drives the sliding rod and the sealing slide to move accurately in the feeding pipe, thereby flexibly adjusting the number of connections between the spray pipe and the feeding pipe, effectively controlling the spraying range, and ensuring accurate coverage of the spraying area. At the same time, the setting of the motor is adjusted so that the movable frame can dynamically change the direction angle of the spraying pipe, perfectly adapting to the complex geometric shape of the door curved surface, avoiding uneven paint film or missed spraying due to fixed angles, and the hot air output by the second air supply device and the hot air delivered by the first air supply device are connected.

After the hot air curtain mixes with the paint mist sprayed from the paint spray tube, a micro-positive pressure environment is formed, which can delay the cooling of the paint mist and improve the leveling, reduce orange peel and dry spray defects, while the normal temperature air curtain effectively lifts the paint mist to prevent heavier paint droplets from settling due to gravity, thereby inhibiting sagging. The two work together to form a stable airflow field dominated by laminar flow in the paint spraying area, and guide the paint spray in a direction, so that the paint mist is deposited along a predetermined trajectory, reducing the uneven paint film caused by turbulence, and effectively improving the utilization rate of the paint.

The flow control plate adopts a straight and curved double-sided design. When the airflow flows out along the straight surface, the air curtain maintains a relatively straight and uniform shape, which is suitable for spraying scenes that require a stable and vertical air curtain. When the airflow flows along the curved air guide surface, the Coanda effect causes the airflow to flow along the curved surface, and the wind curtain will show a certain diffusion or deflection trend, forming a softer and more comprehensive airflow shape, and can effectively suppress the turbulence in the air supply box, ensuring uniform and stable air output, thereby improving the consistency of the spraying quality. By switching or adjusting the angle of the flow control plate, it is possible to flexibly switch between a straight air curtain and a diffusion air curtain, thereby improving the spraying adaptability and quality stability.

[0029] 3. In the present invention, by setting a flip positioning component, the linkage design of the hand crank, rotating rod, rotating gear plate, transmission gear and adjustment screw is used to realize the flexible movement of the second screw seat, so that the spacing between the positioning adsorption devices is adjustable, so as to adapt to new energy vehicle doors of different sizes, which significantly improves the versatility and work efficiency of the equipment. At the same time, the positioning adsorption device fixes the door by adsorption, avoiding the surface damage that may be caused by traditional mechanical clamping and protecting the integrity of the door. The flip motor drives the flip plate to rotate 180 degrees and combines the card limit mechanism of the movable cylinder and the limit block to ensure the stability and precise positioning of the door during the flipping process. The flipping of the flip plate can drive the change of the position of the car door, which is convenient for the staff to install and disassemble the door and improve the processing efficiency.

[0045] The specific implementation method is as follows: by setting up an air curtain spraying assembly 5, through the precise cooperation of the driving motor 512 and the movable screw 514, the first screw seat 511 drives the sliding rod 509 and the sealing slide 510 to move accurately in the feeding tube 506, thereby flexibly adjusting the number of connections between the spraying tube 507 and the feeding tube 506, effectively controlling the spraying range, and ensuring accurate coverage of the spraying area. At the same time, the setting of the motor 12 is adjusted so that the movable frame 516 can dynamically change the orientation angle of the spraying tube 507, perfectly adapting to the complex geometric shape of the door curved surface, avoiding uneven paint film or spraying due to fixed angles, and the second air supply device 50 2 The hot air output and the normal temperature air delivered by the first air supply device 501 together form stable upper and lower air curtains. After the hot air curtains are mixed with the paint mist sprayed from the paint spray pipe, a micro-positive pressure environment is formed, which can delay the cooling of the paint mist and improve the leveling, reduce orange peel and dry spray defects, while the normal temperature air curtains effectively lift the paint mist to prevent heavier paint droplets from settling due to gravity, thereby inhibiting sagging. The two work together to form a stable airflow field dominated by laminar flow in the paint spraying area, and guide the paint spray in a direction so that the paint mist is deposited along a predetermined trajectory, reducing the uneven paint film caused by turbulence, and effectively improving the utilization rate of the paint. At the same time, the double air curtains can block external air disturbances and improve spraying stability.

[0046] The air curtain adjustment assembly 9 includes two symmetrically arranged flow control plates 905, both sides of the flow control plates 905 are connected with a rotating shaft, the rotating shaft is rotatably connected to the air outlet channel 505, the other end of the rotating shaft extends to the outside of the air outlet channel 505 and is connected to a driving gear 902, both sides of the air outlet channel 505 are slidably connected with a movable plate 903, both sides of the movable plate 903 are connected with a movable rack 906, the movable rack 906 is meshed with the driving gear 902, one side of the movable plate 903 is connected to an electric push rod 901, one side of the electric push rod 901 is connected to one side of the air outlet channel 505, both sides of the movable plate 903 are connected with a sliding block 907, both sides of the air outlet channel 505 are connected with two symmetrically arranged fixed slot seats 908, the sliding block 907 is slidably connected to the fixed slot seat 908, and a plurality of flow stabilizing plates 904 distributed in a linear array are connected inside the air outlet channel 505, the cross-section of the flow stabilizing plate 904 is wavy, and the flow control plate 905 is divided into a straight surface and an arc surface.

[0047] The specific implementation method is as follows: the flow stabilizing plate 904 realizes the convenient adjustment of the angle of the flow control plate 905 through the linkage design of the electric push rod 901, the movable plate 903, the movable rack 906 and the driving gear 902. The flow control plate 905 adopts a straight and curved double-sided design. When the airflow flows out along the straight surface, the wind curtain maintains a relatively flat and uniform shape, which is suitable for spraying scenes that require a stable and vertical wind curtain. When the airflow flows along the curved air guide surface, the Coanda effect causes the airflow to flow along the curved surface, and the wind curtain will show a certain diffusion or deflection trend, forming a softer and larger coverage airflow shape, and can effectively suppress the turbulence in the air supply box 504, ensuring uniform and stable air output, thereby improving the consistency of the spraying quality. By switching or adjusting the angle of the flow control plate 905, it is possible to flexibly switch between a flat wind curtain and a diffuse wind curtain, thereby improving the spraying adaptability and quality stability.

[0049] The specific implementation method is as follows: by setting up a flip positioning component 6, through the linkage design of the hand crank 610, the rotating rod, the rotating gear plate 607, the transmission gear 608 and the adjustment screw 609, the flexible movement of the second screw seat is realized, so that the spacing between the positioning adsorption devices 605 is adjustable, so as to adapt to new energy vehicle doors of different sizes, which significantly improves the versatility and work efficiency of the equipment. At the same time, the positioning adsorption device 605 fixes the door by adsorption, avoiding the surface damage that may be caused by traditional mechanical clamping, and protecting the integrity of the door. The flip motor 601 drives the flip plate 606 to rotate 180 degrees and combines the card limit mechanism of the movable cylinder 602 and the limit block 603 to ensure the stability and precise positioning of the door during the flipping process. By flipping the flip plate 606, the position of the car door can be changed, which is convenient for the staff to install and disassemble the door and improve processing efficiency.

[0050] Working principle: When in use, the staff makes the positioning adsorption device 605 face outward, and the staff adjusts the distance between each positioning adsorption device 605 according to the size of the car door. The staff rotates the hand crank 610, and the hand crank 610 drives the rotating rod to rotate, and the rotating rod drives the rotating gear plate 607 to rotate, and the rotating gear plate 607 drives the transmission gear 608 to rotate, and the transmission gear 608 drives the adjusting screw 609 to rotate, and the adjusting screw 609 drives the second screw seat to move, so that the positions between the multiple second screw seats drive the positioning adsorption devices 605 to change.

During the painting process, the linear moving module 4 drives the spray tube 507 from top to bottom through the movable cross frame 10 and the feed tube 506 to complete the complete painting of the car door. During the painting process, the second air supply device 502 stably outputs hot air to the air outlet duct located above, and the first air supply device 501 stably delivers normal temperature air to the air outlet duct located below, thereby forming an air curtain to improve the guidance of paint spraying.

In addition, the staff can adjust the air flow shape according to the actual spraying requirements. The staff starts the electric push rod 901, and the electric push rod 901 drives the movable plate 903 to move, and the movable plate 903 drives the movable rack 906 to move, and the movable rack 906 drives the driving gear 902 to rotate, and the driving gear 902 drives the flow control plate 905 to deflect, so that the contact angle between the flow control plate 905 and the air outlet air flow changes, thereby changing the shape of the output wind curtain.
