Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying, in particular to a rotary spraying device. Background Art
[0002] Rotary spraying is an automated spraying technology that allows the spray gun to rotate around the workpiece, or the workpiece itself to rotate during the spraying process. Rotary spraying can significantly improve the quality and efficiency of the coating while reducing paint waste.
[0003] Current rotary spraying devices primarily rely on the spray gun rotating around a stationary workpiece, or on the workpiece's own rotation, or both the spray gun and the workpiece rotating to perform the spraying operation. However, for some irregularly shaped, multi-faceted workpieces, some surfaces require a specific angle with the spray gun's spray direction for uniform spraying. These methods use a fixed rotation axis—for example, the spray gun rotates vertically downward, while the workpiece's rotation axis is perpendicular to the workbench on which it is placed. This makes it difficult to achieve a specific angle to ensure uniform spraying on certain surfaces of the irregularly shaped workpiece. Utility Model Content

[0024] Reference Figures 1 to 3 The figure shows a rotary spraying device disclosed in the present invention. The rotary spraying device includes a machine platform 100, a conveyor 200, a spray gun 300, and an angle adjustment mechanism 400. The conveyor 200 is movably mounted on the machine platform 100 to transport the workpiece to the spraying position. Optionally, the conveyor 200 may be a synchronous pulley, a synchronous linear motor, or other device. The spray gun 300 is rotatably mounted on the machine platform 100 to achieve the function of changing the spray angle. The angle adjustment mechanism 400 is mounted on the conveyor 200 to deflect the workpiece on the conveyor 200 in any direction in space about a certain center point, thereby cooperating with the spray gun 300 to achieve uniform spraying at a specific angle.
[0025] Specifically, the angle adjustment mechanism 400 includes a bracket 410 , a first semicircular ring 420 , a first rotary driving member 430 , a second semicircular ring 440 , a second rotary driving member 450 , a limiting ball 460 , a first sliding member 470 , and a second sliding member 480 .
[0026] The bracket 410 is fixed to the conveyor 200, and both ends of the first semicircular ring 420 are rotatably mounted on the bracket 410, allowing the first semicircular ring 420 to rotate relative to the bracket 410. The first rotary drive member 430 is fixed to the bracket 410 and is in driving connection with one end of the first semicircular ring 420, allowing the first rotary drive member 430 to drive the first semicircular ring 420 to rotate relative to the bracket 410.
[0027] Both ends of the second semicircular ring 440 are also rotatably mounted on the bracket 410, allowing the second semicircular ring 440 to rotate relative to the bracket 410. To prevent interference between the first and second semicircular rings 420, 440, when rotating simultaneously, the second semicircular ring 440 is positioned inwardly of the first semicircular ring 420, closer to the bracket 410, with the rotation axis of the second semicircular ring 440 perpendicular to that of the first semicircular ring 420. A second rotary drive member 450 is fixedly mounted on the bracket 410 and is in transmission connection with one end of the second semicircular ring 440, allowing the second rotary drive member 450 to drive the second semicircular ring 440 to rotate relative to the bracket 410.
[0028] The limiting ball 460 is located between the second semicircular ring 440 and the bracket 410 , and the rotation plane of the limiting ball 460 and the rotation plane of the second semicircular ring 440 are perpendicular to each other.
[0029] The first sliding member 470 slides simultaneously on the first semicircular ring 420, the second semicircular ring 440, and the limiting ball 460. The first sliding member 470 is simultaneously limited by the first semicircular ring 420, the second semicircular ring 440, and the limiting ball 460. The first sliding member 470 is provided with a clamping portion (not shown in the drawings) that clamps the workpiece during the spraying operation.
[0030] The second sliding member 480 is fixed to the bracket 410. The end of the second sliding member 480 away from the bracket 410 slides on the stop ball 460. At this time, the rotation direction of the stop ball 460 is restricted by the fixed second sliding member 480. Specifically, when the first semicircular ring 420 rotates about its rotation axis, the first sliding member 470 slides along the length of the second semicircular ring 440, and the stop ball 460 rotates accordingly. When the second semicircular ring 440 rotates about its rotation axis, the stop ball 460 is restricted by the fixed second sliding member 480 and does not rotate. At this time, the first sliding member 470 slides along the length of the first semicircular ring 420 while sliding on the stop ball 460.
[0031] In this embodiment, the first semicircular ring 420 is driven to rotate relative to the bracket 410 by the first rotary driving member 430, and the second semicircular ring 440 is driven to rotate relative to the bracket 410 by the second rotary driving member 450. The first sliding member 470 can be deflected in any direction in space with the center when the first semicircular ring 420 and the second semicircular ring 440 are vertically crossed. In this way, the workpiece clamped on the first sliding member 470 can be deflected, and then combined with the spray gun 300, uniform spraying at a specific angle can be achieved.
[0032] In some embodiments of the present invention, Figure 1 、 Figure 2 、 Figure 3 As shown, the limiting ball 460 is provided with a first slide 461 and a second slide 462 which are interconnected, and the center planes where the first slide 461 and the second slide 462 are located are perpendicular to each other, and one end of the first sliding member 470 is embedded in the first slide 461, and one end of the second sliding member 480 is embedded in the second slide 462. When the first semicircular ring 420 rotates, the first sliding member 470 pushes the limiting ball 460 to rotate relative to the second sliding member 480. At this time, the center plane where the first semicircular ring 420 is located is coplanar with the center plane where the first slide 461 is located, and the second sliding member 480 slides in the second slide 462, thereby limiting the limiting ball 460 from deflecting in other directions.
[0033] In some embodiments of the present invention, in order to achieve that the first sliding member 470 is simultaneously limited by the first semicircular ring 420, the second semicircular ring 440 and the limiting ball 460, as shown in FIG. Figure 2As shown, a through-groove 490 is provided on both the first semicircular ring 420 and the second semicircular ring 440, and the first sliding member 470 is simultaneously inserted into both the grooves 490. At this time, when the first semicircular ring 420 rotates about its rotation axis, the first sliding member 470 is limited by the groove 490 on the first semicircular ring 420, pushing the first sliding member 470 to rotate accordingly. However, at the same time, the first sliding member 470 is limited by the groove 490 on the second semicircular ring 440, causing the first sliding member 470 to slide along the length direction of the second semicircular ring 440. Since one end of the first sliding member 470 is engaged in the first slideway 461 on the limiting ball 460, the limiting ball 460 is pushed to rotate, and at this time, the second sliding member 480 slides in the second slideway 462. Similarly, when the second semicircular ring 440 rotates around its rotation axis, the first sliding member 470 is limited by the sliding groove 490 on the second semicircular ring 440, pushing the first sliding member 470 to rotate accordingly, but at the same time is limited by the sliding groove 490 on the first semicircular ring 420, causing the first sliding member 470 to slide along the length direction of the first semicircular ring 420. Since one end of the first sliding member 470 is embedded in the first slide 461 on the limiting ball 460, the first sliding member 470 cannot push the limiting ball 460 to rotate at this time, but the first sliding member 470 can slide in the first slide 461. When the first semicircular ring 420 and the second semicircular ring 440 rotate and cooperate at the same time, the first sliding member 470 deflects in any direction in space about the center when the first semicircular ring 420 and the second semicircular ring 440 vertically intersect. In this way, the workpiece clamped on the first sliding member 470 can be deflected, and then in conjunction with the spray gun 300, uniform spraying at a specific angle can be achieved.
[0034] In some embodiments of the present invention, to prevent the first sliding member 470 from sliding into the second slideway 462 and failing to push the limiting ball 460 to rotate when the first semicircular ring 420 rotates, the length of the end of the first sliding member 470 near the limiting ball 460 is greater than the width of the second slideway 462. Of course, to enable the first sliding member 470 to slide within the first slideway 461, the width of the end of the first sliding member 470 near the limiting ball 460 needs to match the width of the first slideway 461. Similarly, to prevent the second sliding member 480 from sliding into the first slideway 461, the length of the end of the second sliding member 480 near the limiting ball 460 is greater than the width of the first slideway 461.
[0035] In some embodiments of the present invention, the first rotary drive member 430 is a damping motor. This prevents the damping motor's shaft from rotating freely due to even minor forces when the damping motor loses power. Similarly, the second rotary drive member 450 is a damping motor. This prevents the first semicircular ring 420 and the second semicircular ring 440 from rotating when the first sliding member 470 deflects.
[0036] In some embodiments of the present invention, Figure 1 As shown, the rotary spraying device also includes a rotary suspension device 500, one end of the rotary suspension device 500 is connected to the machine platform 100, and the other end of the rotary suspension device 500 is rotatably connected to the spray gun 300, so that the spray gun 300 can rotate around the workpiece below it to achieve comprehensive spraying of the workpiece.
[0037] In some embodiments of the present invention, Figure 1 As shown, the rotary suspension device 500 includes a boom 510 and a turret 520. The upper end of the boom 510 is fixed to the machine platform 100, and the turret 520 is rotatably connected to the lower end of the boom 510. The spray gun 300 is rotatably mounted on the turret 520. When the turret 520 rotates relative to the boom 510, the spray gun 300 can rotate around the workpiece below it. When the spray gun 300 rotates relative to the turret 520, the spray gun 300 can adjust the spray angle.
[0038] In some embodiments of the present invention, Figure 1 As shown, the rotary spraying device further includes a rotary drive device 530, which includes a motor 531 and a rotating shaft 532. The motor 531 is fixedly mounted on the rotating frame 520. The output end of the motor 531 is in driving connection with the rotating shaft 532. The rotating shaft 532 is rotatably mounted on the rotating frame 520, and the spray gun 300 is fixed to the rotating shaft 532. When the motor 531 drives the rotating shaft 532 to rotate, the spray gun 300 rotates relative to the rotating frame 520, and the spray gun 300 can adjust the spray angle.
[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
