These robots use advanced computer control and sensor technology to accurately spray paint on the surface of the car body according to preset parameters to ensure the uniformity and quality of the coating. However, existing robots are generally used in dust-free and windless workshops, but vehicle scratches often occur. At this time, when repairing the paint surface of the car body, it is often impossible to do it in a dust-proof workshop. At this time, the movement of the robot often causes uneven spraying of the paint. Summary of the invention

[0024] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 , to solve the problem of uniform pigment during spraying.

[0027] A car body spraying robot includes a front shell 11, a fixed seat 101 welded inside the front shell 11, the front shell 11 is a hollow structure, a plurality of baffles 12 are provided at the front opening, a plurality of smooth cushions 201 are fixed at the front end of the baffles 12, the plurality of baffles 12 can close the front opening of the front shell 11 by moving, a sliding seat 102 is slidably connected in the fixed seat 101, and a paint nozzle is arranged in front of the sliding seat 102.

[0028] When a vehicle collides, the surface paint will be damaged. During maintenance, spraying is usually performed manually. However, a dust-free and windless environment is generally not possible in a repair shop. As a result, the wind caused by the movement of the spraying equipment will affect the uniformity of the spraying. During the working process of the present invention, the paint is sprayed from the paint nozzle via the sliding seat 102. Initially, multiple baffles 12 are in a closed state. During the spraying process, the flow speed of the gas in the front section spraying process and the rear section deceleration process is in a changing state, which leads to uneven paint in the front section and the rear section of the paint spraying. As a result, the paint in the initial section is first sprayed on the frosted film inside the baffle 12. There is a sandable gap between the frosted film and the baffle 12. The connection is disassembled to facilitate subsequent replacement, and then the baffle 12 is moved around and the sliding seat 102 is moved forward at the same time, so that the paint nozzle is close to the part of the car body that needs to be sprayed, and then the car body is sprayed. During the spraying process, the equipment moves as a whole. During the movement, the wind generated around the paint nozzle is blocked by the baffle 12 to avoid affecting the airflow of the paint spraying, thereby ensuring the uniformity of the spraying. Preferably, the baffle 12 is set to an arc shape to further reduce the resistance during its movement. At the same time, since the paint nozzle is close to the surface of the car body and the surface of the car body is generally uneven, the smooth soft pad 201 set in front of the baffle 12 can protect the car body and avoid friction with the car body during the movement of the equipment.

[0029] like Figure 2 and Figure 3 , in order to solve the problem of synchronous movement of the sliding seat 102 and the baffle 12.

[0030] Multiple first connecting rods 202 are rotatably connected in groups of two on the inner side of each baffle 12, and each group of first connecting rods 202 is arranged in parallel. The other end of each first connecting rod 202 is rotatably connected to the fixed seat 101, and one end of multiple second connecting rods 203 is respectively slidably connected to the first connecting rod 202 located at the rear side in each group, and each second connecting rod 203 is slidably connected to the fixed seat 101. The leading section of each second connecting rod 203 is slidably connected to the third connecting rod 204, the middle section of the third connecting rod 204 is rotatably connected to the fixed seat 101, and the other end of the third connecting rod 204 is slidably connected to the sliding seat 102.

[0031] When the sliding seat 102 is driven to move forward, the lower end of the third connecting rod 204 is driven to move forward, and then the upper end thereof is moved backward, thereby driving the second connecting rod 203 to move relatively backward. At this time, the second connecting rod 203 pulls the first connecting rod 202 backward. The two first connecting rods 202 in each group and the baffle 12 and the fixed seat 101 together form a quadrilateral structure, thereby ensuring that the multiple baffles 12 are synchronously translated and opened backward, thereby achieving the effect that the baffle 12 opens when the sliding seat 102 moves forward. The baffle 12 is set to translate and open, which can ensure that the baffle 12 is always at a certain angle to the paint nozzle after opening, so that it is as close to the paint nozzle as possible, reducing the wind resistance during movement, and further avoiding affecting the uniformity of spraying.

[0032] like Figure 4 and Figure 5 , in order to solve the problem of uneven painting in the front and back sections during the spraying process.

[0033] The paint spray can 104 is arranged behind the sliding seat 102 , and the compression spring 103 is fixed between the fixing seat 101 and the sliding seat 102 . The paint spray can 104 is an existing aerosol can, and the pressure required by the pressure head on the paint spray can 104 is less than the elastic force of the compression spring 103 .

[0034] When performing the spraying operation, the required paint is first prepared according to the color of the vehicle body, and then the paint can is loaded into the paint spray can 104, and then the paint spray can 104 is pressed forward, and then the paint spray can 104 is driven to spray the paint forward, so that the paint passes through the sliding seat 102 and is sprayed out by the paint nozzle. At this time, the forward thrust of the paint spray can 104 is less than the pressure of the compression spring 103, and then the front section of the paint spray can 104 is blocked by the baffle 12, and then the front section of the paint is sprayed on the frosted film inside the baffle 12, and then the paint spray can 104 is continuously applied. The pressure on the paint spray can 104 is reduced, and the compressed compression spring 103 drives the sliding seat 102 to reset, so that the baffle 12 is closed. Then, as the pressure on the paint spray can 104 continues to decrease, the paint spray can 104 stops spraying paint to the outside, and then the rear section of the paint spray is sprayed on the frosted film in the baffle 12, so as to avoid the front and rear sections of the painting process affecting the spraying effect.

[0035] like Figure 5 and Figure 6 , in order to solve the problem of fixing the paint spray can 104.

[0036] The sliding shell 13 is slidably connected in the front shell 11, and the two clamps 301 are slidably connected to the two sides of the sliding shell 13 respectively. A spring is provided between each clamp 301 and the sliding shell 13. The two clamps 301 are in contact with the paint spray can 104. The two pressing plates 302 are fixedly connected to the two clamps 301 respectively, and the two pressing plates 302 are slidably connected to each other.

[0037] When installing the paint spray can 104, first squeeze the two pressing plates 302 inward, so that the clamps 301 on both sides move outward, and squeeze the two springs at the same time, then place the paint spray can 104 between the two clamps 301, stop squeezing the two pressing plates 302, and the springs push the two clamps 301 to fix the paint spray can 104.

[0038] like Figure 7 , in order to solve the problem of uneven spraying caused by pigment precipitation in the paint spray can 104.

[0039] The vibration rod 303 is welded on the upper part of the sliding shell 13 , the vibration rod connecting rod 304 is rotatably connected to the vibration rod 303 , the rotating disk 305 is rotatably connected to the front shell 11 , and the other end of the vibration rod connecting rod 304 is rotatably connected to the eccentric position of the rotating disk 305 .

[0040] The paint in the paint spray can 104 is prone to precipitation, so it needs to be shaken when used to avoid affecting the spraying effect. Before spraying, the turntable 305 is driven to rotate, thereby driving the vibration rod connecting rod 304 to move, and then driving the vibration rod 303 to shake left and right, so that the sliding shell 13 shakes left and right, and then drives the chuck 301 to slide while clamping the paint spray can 104, so as to achieve the purpose of shaking the internal paint evenly.

[0041] like Figure 8 and Fig. 9 , in order to solve the problem of pushing the paint spray can 104 forward.

[0042] The front shell 11 is fixedly connected to the lifting frame 15, the rear shell 14 is slidably connected to the lifting frame 15, the rear shell 14 and the lifting frame 15 are fastened and fixed by bolts, the rear shell 14 and the front shell 11 are detachably connected, the push plate 401 is slidably connected inside the rear shell 14, and the push plate 401 is in contact with the paint spray can 104.

[0043] When installing the paint spray can 104, first move the rear shell 14, then install the paint spray can 104 into the sliding shell 13, then move the rear shell 14 so that it is fixed together with the front shell 11, and during the spraying work, drive the push plate 401 to move forward, thereby pushing the paint spray can 104 and the sliding shell 13 to move synchronously toward the sliding seat 102, and then continue to move the push plate 401 to realize the work of squeezing the nozzle 104 to spray, and when the spraying is completed, move the push plate 401 in the opposite direction to stop the spraying.

[0044] like Figure 8 and Fig. 9 , to solve the problem of moving the push plate 401.

[0045] The screw 402 is fixed to the rear end of the push plate 401, and the screw 402 is slidably connected in the rear shell 14. The internal threaded tube 403 is threadedly matched with the screw 402. The motor 404 is fixed to the lifting frame 15 by bolts, and the output shaft of the motor 404 is driven by the internal threaded tube 403.

[0046] When the push plate 401 needs to be moved, the driving motor 404 works, and then the internal threaded tube 403 is driven to rotate through the pulley and the belt, and then the threaded driving screw 402 moves, and then the push plate 401 is driven to move synchronously. The motor 404 is a servo motor, which can control its forward and reverse rotation by controlling the current, and then control the forward and backward movement of the push plate 401.

[0047] like Figure 1 and Fig.10 , to solve the problem of paint lifting during the spraying process.

[0048] Two telescopic frames 501 are arranged below the lifting frame 15. The lifting frame 15 is a scissor-fork structure formed by multiple long rods. The middle sections of every two adjacent long rods are hinged, and the two ends of the two adjacent groups of long rods are rotatably connected, thereby controlling the two ends of the long rods located below to approach each other, and then the two ends of the two long rods in each group approach each other synchronously, thereby achieving the purpose of extending the lifting frame 15, and then pushing the lifting frame 15 upward. Similarly, when the two ends of the long rods located below move away from each other, the lifting frame 15 is shortened, and the lifting frame 15 is driven to move downward, thereby achieving the purpose of controlling the up and down movement of the spraying point during spraying.

[0049] like Figure 1 and 10 , in order to solve the problem of extension and shortening of the telescopic frame 501.

[0050] The two movable plates 502 are located below the telescopic frame 501 , and the lead screw 503 and the two movable plates 502 are threadedly connected.

[0051] The lead screw 503 is threadedly connected to the two movable plates 502, and the threaded connection directions are opposite, driving the lead screw 503 to rotate, and then the thread drives the two movable plates 502 to move closer or farther away synchronously. When the two movable plates 502 are close to each other, the telescopic frame 501 is extended to achieve the purpose of moving upward for spraying. Similarly, when the lead screw 503 is driven in the reverse direction to rotate, the telescopic frame 501 is shortened to achieve the purpose of moving the spraying point downward.

[0052] like Figure 1 and Fig.10 , to solve the problem of mobile devices.

[0053] The lead screw 503 is slidably connected to the base 504, and a plurality of universal wheels 505 are fixed to the bottom of the base 504 by screws. Since the vehicle body needs to be moved while spraying during the painting work, the mobile base 504 drives the equipment to move, so as to facilitate the spraying work of each part.
