[0037] Currently, for the painting production of rail transit vehicles, a spray-bake paint booth equipped with an automatic spraying system is generally used for production operations. A patent with the Chinese patent publication number CN117983465A discloses an automatic spraying system for rail transit vehicles. The spray-bake paint booth is provided with an electric sliding door to divide the spray-bake paint booth into a working area and a robot preparation area. For the electric sliding door, when the rail transit vehicle needs to move into the working area and when the spraying robot needs to move from the robot preparation area to the working area, the electric sliding door needs to be fully opened, which is time-consuming and energy-consuming, and the spraying efficiency is low.

[0038] In view of the above technical problems, the present utility model proposes a door system device for an automatic spray-bake paint booth of a rail transit vehicle. The combined door formed by the sliding door and the flipping door can effectively improve the spraying efficiency of the automatic spray-bake paint booth. When the rail transit vehicle needs to move into the working area, the sliding door can be opened. When the spraying robot needs to move from the robot preparation area to the working area, the flipping door can be opened.

[0039] The following refers to Figures 1 to 9 As shown, a door system device for an automatic spray-bake paint booth of a rail transit vehicle according to an embodiment of the present utility model is described.

[0040] Referring to Figures 1 to 3 As shown, the automatic spray-bake paint booth includes a first spray-bake area 1, a robot preparation area 3, and a second spray-bake area 2. Both the first spray-bake area 1 and the second spray-bake area 2 are working areas. The entrance is located at the end of the first spray-bake area 1. A robot track 4 and a vehicle conveying track 5 are provided in the automatic spray-bake paint booth. Both the robot track 4 and the vehicle conveying track 5 cover the first spray-bake area 1, the robot preparation area 3, and the second spray-bake area 2, and the robot track 4 is located on both sides, and the vehicle conveying track 5 is located between the robot tracks 4. The robot track 4 is used to convey the spraying robot, and the vehicle conveying track 5 is used to convey the rail transit vehicle.

[0041] It is understandable that the door system device of the automatic spray paint drying room includes a door track assembly 7, a sliding door and a flip door. The door track assembly 7 is arranged at the entrance and inside of the automatic spray paint drying room. In addition, the door track assembly 7 can also be arranged at the exit of the automatic spray paint drying room. The sliding door is arranged between the columns 64 on both sides of the automatic spray paint drying room and is slidably connected to the door track assembly 7. The flip door is arranged on the column 64 and is located on one side of the sliding door. The sliding door and the flip door cooperate to form a combination door. There are two groups of combination doors located between the working area and the robot preparation area 3, and the two groups of combination doors are arranged symmetrically, and the two sliding doors are adjacent. It is worth noting that the door track assembly 7 at the entrance is provided with a sliding door, which is formed by arranging four sliding doors to form a combination door, and the combination door separating the working area and the robot preparation area 3 includes a sliding door and a flip door.

[0042] Reference Figure 2 and Figure 3 As shown, the door track assembly 7 includes a load-bearing track 8, a guide wheel 9, a first driver 10 and a first transmission member 12. The guide wheel 9 is arranged at the top of the sliding door body 35 and is located in the load-bearing track 8. The first driver 10 is arranged on the frame of the automatic spray-drying paint room and is connected to the sliding door body 35 through the first transmission member 12. The first driver 10 is configured as a first motor 11, and the first transmission member 12 is configured as a chain 13. The first motor 11 is connected to the chain 13, and the guide wheel 9 is connected to the chain 13, so that the first motor 11 drives the guide wheel 9 to move in the load-bearing track 8, thereby driving the sliding door body 35 to move. It is worth noting that the chain 13 is arranged in the load-bearing track 8, and the sliding door body 35 is provided with a protrusion that is connected to the chain 13. When the chain 13 moves, the protrusion of the sliding door body 35 is pushed to move, thereby driving the sliding door body 35 to move. Figure 2 As shown in the figure, the load-bearing rail 8, the chain 13 and other components have been separated for easy understanding.

[0043] Reference Figure 4 and Figure 5 As shown, the air-avoiding door 14 is arranged at the notch at the bottom of the sliding door. The air-avoiding door 14 includes a rotating shaft 25, a first combination plate 27 and a flap power mechanism 15. The rotating shaft 25 is rotatably arranged on the sliding door body 35 and arranged horizontally, the first combination plate 27 is connected to the rotating shaft 25, and the flap power mechanism 15 is arranged on the sliding door body 35 and is transmission-connected to the first combination plate 27. The first combination plate 27 can rotate around the rotating shaft 25 under the drive of the flap power mechanism 15 to achieve an upward flipping action.

[0044] It can be understood that the clearance door 14 further includes a bearing plate 24 and a drive plate 26. The bearing plate 24 is arranged on the sliding door body 35 and fixed by rivets. There are three bearing plates 24, which are arranged horizontally and evenly. Bearings are provided on the bearing plate 24, and the rotating shaft 25 passes through the bearings. One end of the drive plate 26 is connected to the first combined plate 27, and the other end is sleeved on the rotating shaft 25. The end of the drive plate 26 sleeved on the rotating shaft 25 is tightened by a tightening bolt so that the drive plate 26 is relatively fixed to the rotating shaft 25. The bearing plate 24 can keep a certain distance between the rotating shaft 25 and the sliding door body 35, and the bearings provided on the bearing plate 24 make the rotation of the rotating shaft 25 smoother. The drive plate 26 can increase the rotation radius of the first combined plate 27 and prevent the first combined plate 27 from interfering with the sliding door body 35 or other adjacent components during rotation.

[0045] It can be understood that the flap power mechanism 15 is provided with a second driver 16, a slide rail 22, a slider 21, a flap force seat 23 and a first connecting rod 18. The second driver 16 is configured as a first cylinder 17. The first cylinder 17 is fixed to the sliding door body 35 through a first base plate 19 and a second base plate 20. Specifically, the first base plate 19 is riveted to the sliding door body 35, the second base plate 20 is riveted to the sliding door body 35, the first base plate 19 and the second base plate 20 are arranged vertically, the first cylinder 17 is located between the first base plate 19 and the second base plate 20 and arranged vertically, one end of the cylinder body of the first cylinder 17 is riveted to the first base plate 19 through a right-angle sheet metal part, and the other end of the cylinder body of the first cylinder 17 is riveted to the second base plate 20 through a right-angle sheet metal part to achieve the fixation of the first cylinder 17.

[0046] The slide rail 22 is arranged on the second base plate 20 and arranged vertically. The slider 21 is arranged on the slide rail 22. The flap force seat 23 is arranged on the slider 21 and extends horizontally. The extended end of the flap force seat 23 is far from the sliding door body 35. One end of the first connecting rod 18 is connected to the horizontally extended end of the flap force seat 23, and the other end is connected to the first connecting rod 18 base arranged on the first combined plate 27. The advantage of the horizontal extension of the flap force seat 23 is that the first connecting rod 18 can be designed shorter to improve the torque transmission efficiency.

[0047] The working principle is as follows: The first cylinder 17 is inflated, and the cylinder push rod of the first cylinder 17 pushes the slider 21 to move downward on the slide rail 22. The flap force seat 23 follows the slider 21 to move. Under the action of the flap force seat 23, the first connecting rod 18 pushes the first combined plate 27 to rotate downward around the axis of the rotating shaft 25 until it is parallel to the sliding door body 35. The second cylinder 31 deflates, and the cylinder push rod of the first cylinder 17 pushes the slider 21 to move upward on the slide rail 22. The flap force seat 23 follows the slider 21 to move. Under the action of the flap force seat 23, the first connecting rod 18 pushes the first combined plate 27 to rotate upward around the axis of the rotating shaft 25 until it is perpendicular to the sliding door body 35.

[0048] It can be understood that a second transmission member 34 is provided at the end of the rotating shaft 25, and the second transmission member 34 is configured as a gear. The sliding door body 35 can also be provided with a fourth driver 32, and the fourth driver 32 is in transmission connection with the second transmission member 34. Since the first combined plate 27 is fixedly connected to the rotating shaft 25 through the driving plate 26, the first combined plate 27 can be driven to rotate by the fourth driver 32 or by the second driver 16. The fourth driver 32 is configured as a servo second motor 33, and the output shaft of the servo second motor 33 is in transmission connection with the gear.

[0049] It should be noted that in addition to being fixedly connected through the driving plate 26 as described above, the rotating shaft 25 and the first combined plate 27 can also be rotatably connected to each other in some other embodiments.

[0050] Refer to Figure 4 and Figure 5 As shown, the clearance door 14 is further provided with a second combined plate 28 and a third driver 30. The second combined plate 28 is provided on one side of the first combined plate 27 through a hinge. The third driver 30 is configured as a second cylinder 31. One end of the second cylinder 31 is fixed on the first combined plate 27 through a sheet metal part, and the cylinder push rod of the second cylinder 31 is fixed on the second combined plate 28 through a sheet metal part.

[0051] It can be understood that the second combined plate 28 can be folded under the drive of the second cylinder 31 and form a 90° angle with the first combined plate 27. The second combined plate 28 can make the notch size of the sliding door body 35 designed larger, and when the sliding door body 35 moves, the second combined plate 28 can be retracted upward to prevent interference with the spraying robot in the robot preparation area 3.

[0052] It can be understood that a first seal 36 is provided at the edge of the first combined plate 27. The first seal 36 is a brush 37. The brush 37 can abut against the sliding door body 35, the ground of the automatic spray baking paint room, and the vehicle conveying track 5 when the first combined plate 27 rotates downward to close, so as to improve the sealing effect of the working area and the robot preparation area 3.

[0053] Referring to Figure 6 as shown, the flipping door includes a flipping door body 38, a link driving mechanism 47, a sixth driver 53 and a track door. The flipping door body 38 is arranged on the column 64 of the side wall of the automatic spray baking paint booth through a hinge and can rotate around the column 64. The link driving mechanism 47 is arranged on the column 64 and is in transmission connection with the flipping door body 38. The flipping door body 38 is driven by the link driving mechanism 47 to realize automatic opening and closing. The sixth driver 53 is arranged at the bottom of the flipping door body 38, the track door is arranged at the bottom of the flipping door body 38, and the sixth driver 53 is in transmission connection with the track door to drive the track door to move up and down in the vertical direction.

[0054] Referring to Figure 7 as shown, the track door is provided with a second guide rail 50 and a second guide block 51. The second guide rail 50 is located on both sides of the track door body 41. The second guide block 51 is arranged on the flipping door body 38 and is slidably connected with the second guide rail 50. The second guide rail 50 is arranged in the vertical direction, and two second guide blocks 51 are arranged on each second guide rail 50. The sixth driver 53 is configured as a fourth cylinder 54. The cylinder block of the fourth cylinder 54 is arranged on the flipping door body 38. The cylinder push rod of the fourth cylinder 54 is connected to the track door body 41. A track door force seat 65 for connecting the cylinder push rod of the fourth cylinder 54 is arranged on the track door body 41.

[0055] The working principle of the track door is as follows: when the fourth cylinder 54 is inflated, the cylinder push rod of the fourth cylinder 54 pushes the track door force seat 65, thereby driving the track door body 41 to move downward. The second guide rail 50 and the second guide block 51 play a guiding role to make the movement of the track door body 41 more stable dynamically; when the fourth cylinder 54 deflates, the cylinder push rod of the fourth cylinder 54 pulls the track door force seat 65, thereby driving the track door body 41 to move upward. The track door body 41 moves more stably under the guiding action of the second guide rail 50 and the second guide block 51. The setting of the track door force seat 65 can increase the stress area of the track door body 41 and improve the transmission efficiency of the thrust of the fourth cylinder 54.

[0056] It can be understood that a second seal 44 is further arranged on the track door body 41. The second seal 44 is located at the bottom edge of the track door body 41. The second seal 44 can abut against the ground or the robot track 4 arranged in the automatic spray baking paint booth to improve the sealing performance of the flipping door. The second seal 44 is configured as a fireproof rubber block 45, and the fireproof rubber block 45 has a relatively thick thickness and good heat insulation effect. In some other embodiments, the second seal 44 can also be arranged on the side of the track door body 41 to improve the sealing performance between the track door body 41 and the flipping door body 38.

[0057] In addition, the track door body 41 is further provided with a frame 46 which protrudes towards the direction of the swing door body 38. The frame 46 divides the track door body 41 into multiple spaces. For example, the second guide rail 50 and the second guide block 51 are located in independent spaces, and the sixth driver 53 is located in an independent space. The advantage of such a design is that it improves the sealing effect of the track door body 41, and the components of the track door are not easily affected by high temperatures.

[0058] Referring Figure 8 and Figure 9 As shown, in the link drive mechanism 47, the fixed seat 48 is fixed on the column 64 of the side wall of the automatic spray baking paint booth by screws or rivets. The fixed seat 48 is provided with two parallel mounting seats 49. The mounting seat 49 is provided with a first guide rail 42. The moving seat 52 is provided with a first guide block 43. The first guide block 43 is slidably connected to the first guide rail 42, so that the moving seat 52 can move along the length direction of the first guide rail 42.

[0059] The fifth driver 39 is configured as a third cylinder 40. The cylinder block of the third cylinder 40 is arranged on the moving seat 52, and the cylinder push rod of the third cylinder 40 is connected to the fixed seat 48. One end of the second link 61 is rotatably arranged on the moving seat 52 through a pin, and the other end is rotatably connected to the sliding seat 59 through a pin. The rocker 55 is divided into two parts. One part is a cylindrical structure 56, and the other part is an arc structure 57. The cylindrical structure 56 is connected to the arc structure 57. The end of the cylindrical structure 56 is rotatably arranged on the fixed seat 48 through a pin. The sliding seat 59 is provided with a chute, and the cylindrical structure 56 is clamped in the chute. The sliding seat 59 can move along the length direction of the cylindrical structure 56 of the rocker 55. The arc structure 57 is provided with an arc channel 58. The connecting seat 60 is arranged on the arc structure 57 through a pin, and the pin passes through the arc channel 58. The connecting seat 60 can slide along the arc channel 58. The arc structure 57 of the rocker 55 is to avoid collision between the front part of the rocker 55 and the connecting seat 60 when moving. The arc channel 58 of the rocker 55 can enable the rocker 55 to perform displacement along a fixed track, and can also enable the rocker 55 to have a large degree of freedom, release the excess power generated by the cylinder through its own displacement movement, avoid mechanism damage, and enable the entire rocker 55 to achieve a large-amplitude flipping action.

[0060] The first rocker arm 62 is used to connect the fixed seat 48 and the rocker 55. One end of the first rocker arm 62 is rotatably arranged on the fixed seat 48, and the other end is rotatably arranged on the rocker 55. The first rocker arm 62 is connected to the fixed seat 48 and the rocker 55 by pins. The second rocker arm 63 is used to connect the fixed seat 48 and the sliding seat 59. One end of the second rocker arm 63 is rotatably arranged on the fixed seat 48, and the other end is rotatably arranged on the sliding seat 59. The first rocker arm 62 is connected to the fixed seat 48 and the sliding seat 59 by pins. It should be noted that the second rocker arm 63 and the second connecting rod 61 use the same pin. The function of the first rocker arm 62 is to further release the excess power generated by the cylinder and avoid damage to the mechanism. The function of the second rocker arm 63 is to stabilize the movement of the slider 21 and the movement of the second connecting rod 61.

[0061] The working principle of the connecting rod drive mechanism 47 is as follows: When the third cylinder 40 is inflated, the cylinder body of the third cylinder 40 will be pushed to the side away from the fixed seat 48, and at the same time, it will drive the moving seat 52 to move outward along the first guide rail 42. The moving seat 52 pulls the second connecting rod 61 outward, and the second connecting rod 61 then pulls the second rocker arm 63 to move downward. The second rocker arm 63 drives the sliding seat 59 to push the rocker 55 to turn outward. While the rocker 55 is turning, the first rocker arm 62 will rotate; during the process of the rocker 55 turning outward, the sliding seat 59 will also move downward along the cylindrical structure 56 of the rocker 55 to achieve a large-amplitude turning action of the rocker 55. When the rocker 55 turns outward, it will drive the arc-shaped structure 57 at its front end to pull the pin, and drive the flip door to open outward through the connecting seat 60. A certain displacement is generated between the arc-shaped channel 58 inside the arc-shaped structure 57 and the pin of the fixed connecting seat 60, further realizing the large-amplitude turning action of the rocker 55, and finally completing the full opening of the flip door.

[0062] When the third cylinder 40 deflates, the cylinder body of the third cylinder 40 will be pulled to the side close to the fixed seat 48, and at the same time, it will drive the moving seat 52 to move inward along the first guide rail 42. The moving seat 52 pulls the second connecting rod 61 inward, and the second connecting rod 61 then pulls the second rocker arm 63 to move upward. The second rocker arm 63 drives the sliding seat 59 to push the rocker 55 to turn inward. While the rocker 55 is turning, the first rocker arm 62 will rotate; during the process of the rocker 55 turning inward, the sliding seat 59 will also move upward along the cylindrical structure 56 of the rocker 55 to achieve a large-amplitude turning action of the rocker 55. When the rocker 55 turns inward, it will drive the arc-shaped structure 57 at its front end to push the pin, and drive the flip door to close inward through the connecting seat 60. A certain displacement is generated between the arc-shaped channel 58 inside the arc-shaped structure 57 and the pin of the fixed connecting seat 60, further realizing the large-amplitude turning action of the rocker 55, and finally completing the full closing of the flip door.

[0063] The working principle of the automatic spray and baking paint booth is as follows:

[0064] Taking the spraying of the polyurethane intermediate layer paint on rail transit vehicles as an example, after the vehicle is polished, it is towed to the front of the automatic spray baking paint booth by the car transfer platform. The operator presses the opening button of the door system device in the central control room 6. At this time, the sliding doors arranged at the outermost end of the automatic spray baking paint booth are slowly opened outward under the drive of the first motor 11 and the chain 13. The sliding doors distributed on both sides of the robot preparation area 3, after receiving the electrical signal from the central control room 6, first trigger the first cylinder 17 on the clearance door 14 below it to start deflating. The cylinder push rod of the first cylinder 17 pulls up the flap force seat 23, and the flap force seat 23 drives the first connecting rod 18 and moves upward along the slide rail 22 under the fixing action of the slider 21. The pulling force generated by the upward movement of the first connecting rod 18 is transmitted to the first combined plate 27 of the clearance door 14 through the connecting rod base 29. After receiving the pulling force, the first combined plate 27 rotates around the rotating shaft 25 under the action of the bearing plate 24 and the driving plate 26, rotating from -90 degrees to 0 degrees to realize the opening of the clearance door 14. After completion, the second combined plate 28 will be flipped to the left again by the second cylinder 31, so that the first combined plate 27 and the second combined plate 28 are arranged in a right-angle space state. After the above instructions are completed, the relevant electrical signals are fed back to the central control room 6, and at the same time, the first motors 11 on both sides of the robot preparation area 3 are triggered to enter the working state, and the sliding doors are opened to both sides through the chain 13. Since the clearance doors 14 on the sliding doors have been opened, the sliding doors effectively avoid the interference of the robot track 4 when moving to the side.

[0065] When all the sliding doors are fully opened, the rail transit vehicle to be sprayed slowly drives into the first spray baking area 1. The operator presses the closing button of the sliding doors on both sides of the robot preparation area 3 in the central control room 6. The electrical signal is sent to the sliding doors, and the first motor 11 is started to pull the two sliding doors in the reverse direction to reach the closed state. After completion, the electrical signal triggers the second cylinder 31 on the second combined plate 28 to inflate, so that the second combined plate 28 and the first combined plate 27 are in a horizontal state. At the same time, the flap power mechanism 15 of the clearance door 14 will also receive the electrical signal and be triggered to start. The first cylinder 17 is inflated, and the cylinder push rod of the first cylinder 17 pushes down the flap force seat 23. The flap force seat 23 drives the first connecting rod 18 and moves downward along the slide rail 22 under the fixing action of the slider 21. The thrust generated by the downward movement of the first connecting rod 18 is transmitted to the first combined plate 27 of the clearance door 14 through the connecting rod base 29. After the first combined plate 27 receives the thrust, it rotates around the rotating shaft 25 under the action of the bearing plate 24 and the driving plate 26, rotating from 0 degrees to -90 degrees to realize the closing of the clearance door 14. After the sliding doors are completely closed, the brushes 37 below the first combined plate 27 and the second combined plate 28 are in full contact with the ground of the automatic spray baking paint booth, filling the gap between the door system device and the ground to achieve the purpose of sealing.

[0066] After all the preparations are completed, the operator presses the flip door opening button in the central control room 6, and the electrical signal is sent to the fourth cylinder 54 on the track door and starts to deflate. The cylinder push rod of the fourth cylinder 54 will drive the track door body 41 through the track door force seat 65, and under the action of the second guide rail 50 and the second guide block 51, it will move vertically upward to open the track door, avoiding interference with the robot track 4 when the flip door is opened. After completion, the electrical signal is fed back to the central control room 6, and at the same time, the link drive mechanism 47 on the flip door is triggered to start working. Two third cylinders 40 are inflated, and the cylinder bodies of the third cylinders 40 will be pushed outward, and at the same time, the moving seat 52 will be driven to pull the second link 61 outward along the length direction of the first guide rail 42. The second link 61 will then pull the second rocker arm 63 to move downward. At the same time, the second rocker arm 63 will drive the sliding seat 59 to push the rocker 55 to turn outward. During the outward turning process, the sliding seat 59 will also move downward along the cylindrical structure 56 at the front end of the rocker 55 to achieve a large-amplitude turning action of the rocker 55. When the rocker 55 turns outward, it will drive the arc-shaped structure 57 at its front end to pull the bolt, and through the connecting seat 60, it will drive the flip door to open outward. A certain displacement is generated between the arc-shaped channel 58 inside the arc-shaped structure 57 and the bolt of the fixed connecting seat 60, further realizing the large-amplitude turning action of the rocker 55, and finally completing the full opening of the flip door. After the flip door is fully opened, the operator controls the spraying robot to enter the first spraying and baking area 1 for spraying operations.

[0067] After the spraying robot enters the first spraying and baking area 1, the operator presses the closing button of the flip door in the central control room 6, and the electrical signal is sent to the link drive mechanism 47 on the flip door. Two third cylinders 40 start to deflate, and the cylinder bodies of the third cylinders 40 will be pulled towards the side close to the fixed seat 48. At the same time, the moving seat 52 will be driven to move inward along the first guide rail 42. The moving seat 52 pulls the second link 61 inward, and the second link 61 then pulls the second rocker arm 63 to move upward. The second rocker arm 63 drives the sliding seat 59 to push the rocker 55 to turn inward, and the first rocker arm 62 will rotate while the rocker 55 turns inward; during the inward turning process of the rocker 55, the sliding seat 59 will also move upward along the cylindrical structure 56 of the rocker 55 to achieve a large-amplitude turning action of the rocker 55. When the rocker 55 turns inward, it will drive the arc-shaped structure 57 at its front end to push the bolt, and through the connecting seat 60, it will drive the flip door to close inward. A certain displacement is generated between the arc-shaped channel 58 inside the arc-shaped structure 57 and the bolt of the fixed connecting seat 60, further realizing the large-amplitude turning action of the rocker 55, and finally the flip door is fully closed. At the same time, the electrical signal triggers the fourth cylinder 54 of the track door to inflate. The cylinder push rod of the fourth cylinder 54 will drive the track door body 41 through the bottom force seat, and under the action of the second guide rail 50 and the second guide block 51, it will move vertically downward. The soft and thickened fireproof rubber plate under the track door body 41 is completely attached to the surface of the robot track 4 to ensure the sealing of the entire flip door and realize the closing of the track door.

[0068] When the first spray-baking zone 1 is performing the spraying operation on a vehicle, another vehicle will also be poured into the second spray-baking zone 2 through the car transfer platform and perform preparatory work before spraying such as cleaning and protection in the second spray-baking zone 2. At this time, the operator presses the closing button of the outermost sliding door of the automatic spray-baking paint booth in the central control room 6, and the two sliding doors are slowly closed under the drive of the first motor 11 and the chain 13. Due to the excellent partitioning and sealing performance of the door system device of the automatic spray-baking paint booth, the preparatory work in the second spray-baking zone 2 is not affected by the paint mist, etc. in the first spray-baking zone 1 at all. After about one hour, the spraying work in the first spray-baking zone 1 is completed, and at the same time, the preparatory work in the second spray-baking zone 2 is also completed. The operator will open the flip door according to the method described above. The spraying robot moves to the robot preparation area 3, and after the material is filled at the same time, it moves to the second spray-baking zone 2. Then, the operator will close all the flip doors. The first spray-baking zone 1 will perform the leveling and drying operations after the paint spraying is completed, while the second spray-baking zone 2 will perform the spraying operation on another vehicle. When the spraying operation in the second spray-baking zone 2 is completed, the operator opens the flip door on the side of the second spray-baking zone 2 according to the method described above, moves the spraying robot to the robot preparation area 3 for cleaning work such as the spray gun, and then closes the flip door. The second spray-baking zone 2 will also enter the leveling and drying working condition.
