Description

Technical Field

[0001] This invention relates to the field of spraying technology, specifically to a jig disc rotation and movement system and a corresponding spray booth. Background Technology

[0002] Accumulation chain conveyor systems, as highly automated integrated space storage and transportation systems, are widely used in painting operations in the automotive, 3C digital, and home appliance industries. Common accumulation chain conveyor systems include accumulator chain conveyor systems and cycle conveyor systems. Taking an accumulation chain conveyor system as an example, it typically includes a carrier device for placing the workpiece to be painted, a carrier rail for carrying the carrier device, and an accumulation chain that pulls the carrier device located on the carrier rail. As the accumulation chain moves continuously, the carrier device intermittently contacts and disengages from the accumulation chain. The painting equipment performs painting operations on the workpiece to be painted on one side of the accumulation chain, thus achieving phased dwell times within the process workshop and movement to downstream process workshops.

[0003] Current stacking chains typically use a motor-driven traction chain, which in turn drives a jig carriage. The jig carriage has a stopping device at the required station to allow the carriage to stop and start freely. However, the current carrying device cannot arbitrarily adjust or control the rotation angle; it can only rotate in multiples of 90°, making it impossible to perform spraying operations at various angles. This increases the difficulty of production and processing, therefore, it is necessary to improve upon these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a jig disc rotation and movement system and a corresponding spray booth, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a jig disc rotation and movement system for rotating or fixing a jig disc on a jig cart, comprising:

[0006] A rotating mechanism is provided on the jig cart and carries the jig disk. The rotating mechanism includes a main shaft, a jig rod, a sprocket, and a limiting assembly. The main shaft is provided on the jig cart, the jig rod is movably installed inside the main shaft, and the sprocket and the limiting assembly are both fixedly installed on the jig rod.

[0007] A rotary drive mechanism is intermittently connected to the sprocket drive and drives the sprocket to rotate around the main shaft as the center point.

[0008] A displacement drive mechanism is connected to the rotary drive mechanism and drives the rotary drive mechanism to intermittently contact or move away from the sprocket.

[0009] A guiding mechanism is provided for abutting connection with the limiting component.

[0010] Preferably, the guiding mechanism includes a guide bracket, a guide strip, and a guide cylinder. The guide cylinder is fixedly installed on the guide bracket and is throttle-connected to the guide strip. The guide strip is used to contact and connect with the limiting component.

[0011] Preferably, the guiding mechanism further includes a mounting groove, and the number of the guiding cylinders is two. Both guiding cylinders are fixedly mounted on the guiding bracket. The two ends of the mounting groove are respectively connected to the two guiding cylinders for transmission, and the guide strip is disposed in the mounting groove.

[0012] Preferably, the limiting assembly includes a limiting fixing plate and at least two limiting bearings. The limiting fixing plate is fixedly connected to the jig rod and the sprocket respectively. The at least two limiting bearings are all disposed on the limiting fixing plate and are in contact with the guide mechanism.

[0013] Preferably, the number of the limiting bearings is four sets, the limiting fixing plate is approximately square, and the four sets of limiting bearings are respectively located at the four vertices of the limiting fixing plate;

[0014] or

[0015] The number of the limiting bearings is three sets, and the limiting fixing plate is roughly in the shape of an equilateral triangle. The three sets of limiting bearings are respectively located at the three vertices of the limiting fixing plate.

[0016] Preferably, the device further includes a clamping and positioning mechanism, which includes a fixed support, a clamping cylinder, an active clamp, and a passive clamp. The clamping cylinder, the active clamp, and the passive clamp are all movably mounted on the fixed support. The active clamp is driven by the passive clamp, and the clamping cylinder is driven by the active clamp. Under the drive of the clamping cylinder, the active clamp and the passive clamp clamp the spindle on both sides respectively.

[0017] Preferably, the rotary drive mechanism includes a reduction gearbox, a drive motor, and a dial. The reduction gearbox is mounted on the displacement drive mechanism, the drive motor is connected to the dial via the reduction gearbox, and the dial is intermittently connected to the sprocket.

[0018] Preferably, the dial includes a drive shaft, a fixed disk, and a plurality of shift pins. The drive shaft is located at the center of the fixed disk and is connected to the gearbox. The plurality of shift pins are evenly arranged on the fixed disk in the circumferential direction and are in contact with the sprocket.

[0019] Preferably, the rotating mechanism further includes a locking component, the middle of which is movably connected to the main shaft, and the two ends of the locking component are respectively provided with a locking part and a counterweight. The sprocket has a locking hole, and the locking part is used to engage with the locking hole. One end of the locking component is provided with a guide post. The guiding mechanism includes a guide plate, which has a guide surface and a support surface. The guide surface and the support surface have an included angle of less than 180°.

[0020] When the jig carriage moves forward, the locking part engages with the locking hole due to the weight of the counterweight; until the jig carriage moves to the guide mechanism, the guide post first contacts the guide surface, and under the action of the guide surface, the guide post is guided to the support surface, at which point the locking part disengages from the locking hole.

[0021] Correspondingly, the present invention also provides a spray booth, comprising:

[0022] An accumulation chain track, on which a jig cart is slidably mounted, and on one side of the accumulation chain track is a jig disk rotation and movement system as described above;

[0023] A robotic arm painting system is located above the accumulation chain track and is used to process the workpieces to be processed in the fixture vehicle.

[0024] An air circulation system is provided, comprising a ventilation duct, a fan, an exhaust gas treatment device, an air supply device, an air conditioning unit, and a pressure equalization box. The ventilation duct is connected to the robotic arm painting system. The fan drives the airflow to pass sequentially through the exhaust gas treatment device, the air supply device, the air conditioning unit, and the pressure equalization box before entering the painting booth.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In this invention, the jig carriage carries the workpiece to a preset position and then stops. The displacement drive mechanism drives the rotary drive mechanism to connect with the sprocket. Subsequently, the rotary drive mechanism operates, driving the sprocket to rotate. The jig rod, which is fixedly connected to the sprocket, drives the jig disc to rotate synchronously, thereby facilitating the spraying equipment to perform spraying operations on the workpiece in the jig disc. Depending on the complexity and degree of processing of the workpiece, the workpiece can be rotated to any angle from 0° to 360° for spraying operations, with the rotation accuracy controlled by the rotary drive mechanism.

[0027] It can perform continuous rotary spraying or spray a specific area repeatedly in both directions. When needed, it can also achieve precise positioning at multiples of 90° through the cooperation of the guiding mechanism and the limiting mechanism. This overcomes the shortcomings of traditional equipment that can only rotate by multiples of 90°, effectively reducing the difficulty of production operations and improving production efficiency.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1One embodiment of the present invention provides a jig disc rotation and movement system for rotating or fixing a jig disc 62 on a jig carriage 61. A rotating mechanism 1 is provided between the jig carriage 61 and the jig disc 62. The rotating mechanism 1 carries and drives the jig disc 62 to rotate, so as to provide spraying operations at various angles. It includes a main shaft 11, a jig rod 12, and a sprocket 13. The main shaft 11 is generally hollow and is fixedly installed on the jig carriage 61. Several bearings are installed inside the main shaft 11. One end of the jig rod 12 is located inside the main shaft 11 and is movably connected to the main shaft 11 through a bearing, and the other end is connected to... The jig disc 62 is fixedly connected, and the sprocket 13 is located between the main shaft 11 and the jig rod 12 and is fixedly connected to the jig rod 12. The sprocket 13 is powered by the rotary drive mechanism 2 so that the sprocket 13 can drive the jig rod 12 to rotate within the main shaft 11. The limiting component 14 is fixedly installed at the lower end of the jig rod 12 and is used to abut against the guide mechanism 4 so that the guide mechanism 4 can provide auxiliary positioning during rotation. The rotary drive mechanism 2 is located on the displacement drive mechanism 3 and is used to drive the rotary drive mechanism 2 to contact or disengage from the sprocket 13 to prevent the jig carriage 61 from encountering jamming or collision when it moves.

[0041] During operation, the jig carriage 61 within the accumulating chain track 6 carries the workpiece to a preset position and then stops. The displacement drive mechanism 3 drives the rotary drive mechanism 2 to connect with the sprocket 13. Subsequently, the rotary drive mechanism 2 operates, driving the sprocket 13 to rotate. The jig rod 12, fixedly connected to the sprocket 13, drives the jig disc 62 to rotate synchronously, thus facilitating the spraying equipment to perform spraying operations on the workpiece within the jig disc 62. Depending on the complexity and processing degree of the workpiece, it can be rotated to any angle from 0° to 360° for spraying operations, or continuous rotary spraying can be performed, or a specific area can be sprayed repeatedly in both forward and reverse directions. During this process, the guide mechanism 4 abuts against the limiting component 14 to provide precise angle positioning when needed. After processing is completed, the displacement drive mechanism 3 drives the rotary drive mechanism 2 to disengage from the sprocket 13, allowing the jig carriage 61 to carry the workpiece to the next process.

[0042] Please see Figure 2 and Figure 3 More specifically, the limiting component 14 in this embodiment includes a limiting fixing plate 141 and four sets of limiting bearings 142. The limiting fixing plate 141 is fixedly connected to the jig rod 12 and the sprocket 13 respectively, and the limiting fixing plate 141 is approximately square. The four sets of limiting bearings 142 are respectively located at the four vertices of the limiting fixing plate 141. After the rotation drive mechanism 2 drives the sprocket 13 to rotate, the guide mechanism 4 exerts force to hold the limiting bearings 142, so that the two sets of limiting bearings 142 on the side closer to the guide mechanism 4 can be tightly attached to the guide bar 42. This ensures that the guide mechanism 4 contacts and limits the limiting bearings 142 every 90° rotation of the jig disk 62, thus ensuring high rotational accuracy when processing the set angle.

[0043] In the above structure, the limiting fixing plate 141 can be selected in different shapes such as triangle, hexagon or octagon according to the different required rotation positioning angles. For example, if 60° angle positioning is required, a hexagonal limiting fixing plate 141 can be selected. The number of limiting bearings 142 is the same as the number of vertices of the limiting fixing plate 141 and they are respectively set at the vertices of the limiting fixing plate 141 so that they can contact the guide mechanism 4 after the sprocket 13 has rotated.

[0044] Please see Figure 6 More specifically, the guiding mechanism 4 includes a guide bracket 41, a guide strip 42, a guide cylinder 43, and a mounting groove 44. There are two guide cylinders 43, both of which are mounted on the guide bracket 41. The piston rods of the two guide cylinders 43 are respectively connected to both ends of the mounting groove 44, and both guide cylinders 43 are supplied with air by the same air pipe so that they can exert force on the mounting groove 44 from both sides at the same time, preventing uneven force from the guide cylinders 43 from causing skewing. The guide strip 42 is made of PP material and is installed in the mounting groove 44, which can effectively buffer the impact force when the equipment contacts and is easy to replace after wear.

[0045] Please see Figure 4 More specifically, the rotary drive mechanism 2 includes a reduction gearbox 21, a drive motor 22, a dial 23, and a servo driver. The reduction gearbox 21 is mounted on two sliders 33 on both sides. The drive motor 22 is electrically connected to the servo driver and is also connected to the reduction gearbox 21 for transmission. The power is transmitted to the dial 23 after being reduced in speed and increased in torque by the reduction gearbox 21. The dial 23 drives the sprocket 13 to rotate, thereby causing the jig disk 62 and the workpiece to rotate, which facilitates production and processing operations.

[0046] The drive motor 22 is controlled by a servo driver, which can precisely adjust the rotation angle of the jig disk 62 according to the rotation speed of the drive motor 22, so as to achieve functions such as continuous rotation from 0° to 360°, rotation to a fixed angle, or continuous forward and reverse rotation within a certain angle range.

[0047] More specifically, the dial 23 includes a drive shaft 24, a fixed plate 25, and several shift pins 26. The drive shaft 24 is located at the center of the fixed plate 25 and is connected to the power output shaft of the reduction gearbox 21, which provides rotational power. There are two fixed plates 25, which are respectively located at both ends of the drive shaft 24 and are fixed with shift pins 26 on both sides. Several shift pins 26 are evenly arranged on the fixed plate 25 in a circumferential direction. They are used to contact the sprocket 13 and drive the sprocket 13 to rotate when the dial 23 rotates. The dial 23 has a profile gear structure with small clearance, which allows for precise control of the jig plate 62 to stop at any angle position from 0° to 360°. The transmission is stable, enabling spraying at any angle from 0° to 360° and continuous rotational spraying. At the same time, it is convenient to replace individual shift pins 26, resulting in low operating costs.

[0048] Please see Figure 5 More specifically, the displacement drive mechanism 3 includes a slide rail fixing seat 31, a slide rail 32, a slider 33, a drive clamping cylinder 524, and a stop block 35. The slide rail fixing seat 31 is fixed to one side of the accumulation chain track 6. There are two slide rails 32 and two sliders 33. There are four stop blocks 35. The two slide rails 32 are fixedly installed on both sides of the slide rail fixing seat 31 and are perpendicular to the accumulation chain track 6. The two sliders 33 are respectively set on the two slide rails 32. The four stop blocks 35 are respectively set at both ends of the two slide rails 32 to block the sliders 33 and prevent them from falling off. The rotation drive mechanism 2 is fixedly installed on the slider 33 and is driven by the drive clamping cylinder 524 to slide on the slide rail 32 so as to contact or disengage from the sprocket 13.

[0049] During operation, the drive clamping cylinder 524 pushes the rotary drive mechanism 2 to slide on the slide rail 31. The stop block 35 can provide a buffer for the rotary drive mechanism 2 to prevent the excessive thrust of the drive clamping cylinder 524 from causing impact damage to the equipment until the rotary drive mechanism 2 contacts the sprocket 13, providing power for the rotation of the fixture disk 62. After the operation is completed, the drive clamping cylinder 524 retracts, causing the rotary drive mechanism 2 to disengage from the sprocket 13. Then the fixture cart 61 carries the workpiece to the next process.

[0050] Please see Figure 6 and Figure 8This invention provides a second embodiment. This embodiment is basically the same as the first embodiment, except that: the rotating mechanism 1 is further provided with a locking member 15, the middle part of which is movably connected to the main shaft 11, and the two ends of the locking member 15 are respectively provided with a locking part 151 and a counterweight 152. The sprocket 13 is provided with a locking hole 131, and the locking part 151 is used to engage with the locking hole 131. One end of the locking member 15 is provided with a guide post 153. The guiding mechanism 4 also includes a guide plate 45, which is fixedly connected to the guide bracket 41 by two L-shaped brackets. The guide plate 45 is provided with a guide surface 451 and a support surface 452. The guide surface 451 and the support surface 452 have an angle of less than 180°. When the jig trolley 61 moves, the locking member 15 moves away from the locking part. One end of 151 naturally droops due to the weight of the counterweight 152, thereby engaging the locking part 151 with the locking hole 131. After the jig carriage 61 moves to the guide mechanism 4, the guide post 153 first contacts the guide surface 451. Under the force of the jig carriage 61 moving and the upward lifting action of the guide surface 451, the guide post 153 is guided to the support surface 452. At this time, the locking part 151 disengages from the locking hole 131, and the sprocket 13 can rotate freely. After the processing is completed, the jig carriage 61 continues to move, the guide post 153 disengages from the support surface 452, and the counterweight 152 droops again due to its own weight, so that the sprocket 13 is fixed by the locking part 151, preventing the sprocket 13 from rotating arbitrarily when the jig carriage 61 moves, which would cause equipment failure.

[0051] Please see Figure 6 and Figure 7 This invention provides a third embodiment. This embodiment is basically the same as embodiment two, except that it also includes a clamping and positioning mechanism 5. The clamping and positioning mechanism 5 includes a fixed support 51, a clamping cylinder 52, an active clamp 53, and a passive clamp 54. The fixed support 51 is provided with a cylinder movable seat 513 and two rotational fulcrums 514. The active clamp 53 and the passive clamp 54 are movably connected to the fixed support 51 through the two rotational fulcrums 514, respectively. The active clamp 53 is provided with a first gear set 531, and the passive clamp 54 is provided with a second gear set 541. The first gear set 531 and the second gear set 541 mesh with each other. The clamping cylinder 52 is movably mounted on the cylinder movable seat 513, and the push rod of the clamping cylinder 52 is movably connected to the active clamp 53.

[0052] During operation, the piston rod of the clamping cylinder 52 pushes the active clamp 53 to rotate. The active clamp 53 transmits power to the second gear set 541 through the first gear set 531, thereby driving the passive clamp 54 to rotate synchronously. The main shaft 11 is clamped from both sides to fix the jig carriage 61 and provide support when the jig plate 62 rotates, which can effectively reduce the vibration of the equipment during rotation and facilitate the spraying operation of the spraying equipment on the workpiece in the jig plate 62. After processing is completed, the push rod of the clamping cylinder 52 retracts, causing the active clamp 53 and the passive clamp 54 to rotate and open, allowing the jig carriage 61 to pass through.

[0053] More specifically, the fixed support 51 includes a support plate 512 and two mounting columns 511. Both mounting columns 511 are fixedly installed on the workbench surface. The support plate 512 is fixedly installed on the upper end of the two mounting columns 511. The workbench surface is provided with studs. The studs are fixedly connected to the support plate 512 and the workbench surface respectively through preset threaded holes, so as to support the support plate 512 from below, thereby raising the support plate 512 relative to the workbench surface to a certain height. This facilitates the installation of equipment under the support plate 512 or the adjustment of the height of the support plate 512 to accommodate jig carts 61 of different heights.

[0054] More specifically, the support plate 512 has a vertical part and a horizontal part. The vertical part is used to fix the two mounting columns 511. The lower surface of the horizontal part is fixedly connected to the stud to fix the support plate 512. The horizontal part has a clearance area, which is adapted to the shape and position of the clamping cylinder 52 so that the clamping cylinder 52 is installed as low as possible to reduce the size of the equipment. The active clamp 53 and the passive clamp 54 are both installed on the upper surface of the horizontal part.

[0055] During assembly, first, the two mounting posts 511 and studs are fixed to their preset positions, and then the support plate 512 is installed. The support plate 512 is integrally formed from a vertical part and a horizontal part, forming a 90° angle between the vertical and horizontal parts. Both the vertical and horizontal parts are pre-drilled with several mounting holes. The vertical part is fixedly installed to the two mounting posts 511 through the mounting holes, and the horizontal part is fixedly connected to the studs on the worktable through the mounting holes, thereby fixing the support plate 512. Then, the active gripper 53 and the passive gripper 54 are placed, bolts are inserted and fixed to serve as the rotation fulcrum 514, and the cylinder movable seat 513 is fixedly installed to the vertical part. Then, the clamping cylinder 52 is connected to the cylinder movable seat 513 through a snap ring, and the piston rod of the clamping cylinder 52 is connected to the active gripper 53. The assembly is now complete.

[0056] More specifically, the active gripper 53 is provided with a first gripping part 532 and a transmission part 533, and the passive gripper 54 is provided with a second gripping part 542. The first gear set 531 is located at the junction of the transmission part 533 and the first gripping part 532, so that the first gripping part 532 is roughly in the shape of a "V". The rotation fulcrum 514 is located at the center of the first gear set 531. The gripping cylinder 52 is connected to the transmission part 533, which drives the active gripper 53 to rotate around the rotation fulcrum 514. At the same time, the first gear set 531 and the second gear set 541 mesh and drive, driving the passive gripper 54 to rotate. This allows the first gripping part 532 and the second gripping part 542 to grip and fix the jig carriage 61 from both sides, so that the distance between the spraying equipment and the workpiece in the jig carriage 61 meets the preset distance, which facilitates the spraying equipment to perform spraying operations on the workpiece in the jig carriage 61.

[0057] More specifically, the active gripper 53 is provided with a first gear set 531, a first clamping part 532 and a transmission part 533, and the passive gripper 54 is provided with a second gear set 541 and a second clamping part 542. The first gear set 531 is located at the junction of the transmission part 533 and the first clamping part 532. The clamping cylinder 43 is connected to the transmission part 533. The first clamping part 532 and the second clamping part 542 are respectively in contact with the main shaft 11 on both sides.

[0058] More specifically, the first clamping part 532 and the second clamping part 542 are both adapted to the outer surface shape of the spindle 11 and wrap around the spindle 11 from multiple directions to ensure that the spindle 11 will not shift in any direction, so as to better position and fix the jig 61 and facilitate production and processing operations.

[0059] More specifically, the first gear set 531 and the second gear set 541 are both sector gears with a center angle of at least 120° to ensure that the active gripper 53 and the passive gripper 54 do not obstruct the passage of the jig trolley 61 when they are opened.

[0060] The following will combine Figures 1 to 8 Examples 1 to 3 further illustrate the working principle of the present invention.

[0061] like Figure 1 As shown, the jig carriage 61 moves from the upper right corner to the lower left corner. The workpiece to be painted is placed in the jig tray 62. The locking part 151 is raised due to the weight of the counterweight 152 and engages with the locking hole 131 to prevent the sprocket 13 from rotating without reason. At the same time, the driving clamping cylinder 524 and the clamping cylinder 52 are in the retracted state. The rotary drive mechanism 2 is retracted to one side of the accumulation chain track 6. The active clamp 53 and the passive clamp 54 are in the open state so as not to block the jig carriage 61 from passing.

[0062] Upon reaching the guide mechanism 4, the guide post 153 is raised under the action of the guide plate 45, causing the locking part 151 to disengage from the locking hole 131, unlocking the sprocket 13. At this time, the displacement drive mechanism 3 and the clamping and positioning mechanism 5 work in succession. The clamping cylinder 52 pushes the active clamp 53 and the passive clamp 54 to clamp and fix the main shaft 11, and drives the clamping cylinder 524 to push the rotary drive mechanism 2, causing the dial 23 to approach the sprocket 13. At this time, the drive motor 22 operates, and the power is reduced and increased in torque by the reduction gearbox 21 before being transmitted to the dial 23 to drive the sprocket 13 to rotate. This drives the fixture rod 12 and the fixture disk 61 to rotate synchronously, thereby facilitating the spraying equipment to perform spraying operations on the workpiece in the fixture disk 61. Depending on the complexity and processing degree of the workpiece, the workpiece can be rotated to any angle from 0° to 360° for spraying operations, or continuous rotary spraying can be performed, or a certain area can be sprayed repeatedly in both forward and reverse directions. When the sprocket 13 rotates, the guide bar 42 provided on the guide mechanism 4 always supports the several limit bearings 142 installed on the sprocket 13, thereby achieving precise positioning when rotating to a multiple of 90°.

[0063] After processing is completed, the drive motor 22 stops operating, the displacement drive mechanism 3 drives the rotary drive mechanism 2 to disengage from the sprocket, the clamping cylinder 52 retracts, causing the active clamp 53 and the passive clamp 54 to release the spindle 11, the jig carriage 61 continues to move, causing the guide column 153 to disengage from the support surface 452, the locking part 151 is lifted due to the weight of the counterweight block 152, and engages with the locking hole 131 again.

[0064] Please see Figure 9 The present invention also provides a spray booth, including an accumulation chain track 6, a robotic arm spray painting system, and an air circulation system 9.

[0065] A jig cart 61 is slidably mounted on the accumulation chain track 6, and a jig disk rotation and movement system 7 as described above is provided on one side of the accumulation chain track 6.

[0066] The robotic arm painting system 8 is located above the accumulation chain track 6 and is used to process the workpieces to be processed in the jig 61.

[0067] The air circulation system 9 includes a ventilation duct 91, a fan 92, an exhaust gas treatment device 93, an air supply device 94, an air supply air conditioner 95, and a pressure equalization box 96. The ventilation duct 91 is connected to the robotic arm painting system 8. The fan 92 drives the airflow to enter the painting booth after passing through the exhaust gas treatment device 93, the air supply device 94, the air supply air conditioner 95, and the pressure equalization box 96 in sequence.

[0068] During operation, the accumulation chain track 6 drives the jig carriage 61 to the preset position. The robotic arm painting system 8 processes the workpiece carried in the jig carriage 61. Subsequently, the paint mist in the air settles in the settling tank 82 under the washing of the spray nozzle 81. The remaining relatively clean airflow enters the ventilation pipe 91 under the action of the fan 92. First, it is purified and separated by the exhaust gas treatment device 93. The exhaust gas is discharged into the exhaust port 931 for collection. The remaining clean air enters the air supply device 94 and mixes with the fresh air entering through the air inlet 941. After temperature and humidity adjustment by the air supply air conditioner 95 and pressure adjustment by the pressure equalization box 96, it enters the paint booth to achieve internal airflow circulation.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
