The various technical features in the utility model creation can be combined interactively on the premise of not mutually contradictory and conflicting.

[0025] Please see Figure 1This utility model provides a spraying mechanism, including a support 1, a lifting member 2, a first translation member 3, a second translation member 4, and several spraying components 5. The spraying components 5 are all mounted on the support 1. The support 1 is mounted on the output end of the lifting member 2, which drives the support 1 to move up and down. The lifting member 2 is mounted on the output end of the first translation member 3, which drives the lifting member 2 to move horizontally. The first translation member 3 is mounted on the output end of the second translation member 4, which drives the first translation member 3 to move horizontally. The movement direction of the lifting member 2 is perpendicular to the movement direction of the first translation member 3. The translation direction of the lifting member 2 is defined as the X direction, the translation direction of the first translation member 3 as the Y direction, and the lifting direction of the support 1 as the Z direction. Under the combined action of the lifting member 2, the first translation member 3, and the second translation member 4, the support 1 can move in the X, Y, and Z directions, thereby driving the spraying components 5 to move in three mutually perpendicular directions in three-dimensional space, enabling the spraying components 5 to accurately align and spray the workpiece.

[0026] Please see Figure 2 and Figure 3 Specifically, the spraying assembly 5 includes a first rotating component 51, a second rotating component 52, a spray gun 53, a connecting frame 54, and a blocking cylinder 55. The spray gun 53 is mounted on the output end of the first rotating component 51, which drives the spray gun 53 to rotate. The first rotating component 51 is mounted on the connecting frame 54, which is mounted on the output end of the second rotating component 52. The second rotating component 52 drives the connecting frame 54 to rotate, and the rotation direction of the connecting frame 54 is perpendicular to the rotation direction of the spray gun 53. By driving the spray gun 53 to rotate through the first rotating component 51 and the connecting frame 54 to rotate through the second rotating component 52, and because the rotation direction of the connecting frame 54 is perpendicular to the rotation direction of the spray gun 53, the connecting frame 54 can drive the spray gun 53 to rotate in a direction perpendicular to its own rotation direction. This allows the spray gun 53 to spray the workpiece from top to bottom and left to right, simultaneously covering the top and sides of the workpiece, resulting in good spraying quality.

[0027] Please see Figure 2 Furthermore, the cylinder body of the blocking cylinder 55 is mounted on the connecting frame 54, and the piston rod of the blocking cylinder 55 is used to abut against the spray gun 53. The blocking cylinder 55 can rotate with the connecting frame 54. When it is necessary to stop the rotation of the spray gun 53, the first rotating member 51 is closed, and the piston rod of the blocking cylinder 55 extends and abuts against the spray gun 53 to stop the rotation of the spray gun 53.

[0028] Please see Figure 3The first rotating component 51 includes a rotary cylinder 511. The cylinder body of the rotary cylinder 511 is mounted on the connecting frame 54. The output shaft of the rotary cylinder 511 is connected to the spray gun 53, and the rotation direction of its output shaft is vertical. When the rotary cylinder 511 is started, its output shaft can drive the spray gun 53 to rotate in the vertical direction. The rotary cylinder 511 has a compact structure and can save installation space.

[0029] Please see Figure 4 The spray gun 53 is connected to a connecting plate 531, which has a connecting hole 532. One end of the output shaft of the rotary cylinder 511 is located inside the connecting hole 532, and the output shaft of the rotary cylinder 511 is sleeved with a cylinder flange 512. The bottom of the cylinder flange 512 is mounted on the connecting plate 531. The cylinder flange 512 helps to ensure a firm connection between the output shaft of the rotary cylinder 511 and the connecting plate 531, preventing the connecting plate 531 from causing the spray gun 53 to fall off during rotation.

[0030] In this embodiment, a cover plate 513 is provided at the end of the output shaft of the rotary cylinder 511. The cover plate 513 abuts against the cylinder flange 512, and the cover plate 513 is fixedly connected to the output shaft of the rotary cylinder 511 by bolts (not shown in the figure). The cover plate 513 can play the role of dust prevention and sealing.

[0031] Please see Figure 5 The second rotating component 52 includes a servo motor 521, which is mounted on the bracket 1. The rotating shaft of the servo motor 521 is connected to the connecting frame 54, and the rotation direction of its rotating shaft is horizontal. The rotation of the connecting frame 54 in the horizontal direction is achieved by the rotation of the rotating shaft of the servo motor 521. The connecting frame 54 drives the spray gun 53 to rotate in the horizontal direction, so that the spray gun 53 can rotate in both the horizontal and vertical directions to fully spray the workpiece.

[0032] The bracket 1 is provided with a connecting groove 11, and a bearing 111 is provided in the connecting groove 11. The rotating shaft of the servo motor 521 passes through the bearing 111. The bearing 111 can support the rotating shaft of the servo motor 521 to rotate relative to the bracket 1, reduce the coefficient of friction during its movement, and ensure its rotational accuracy.

[0033] Furthermore, a first through hole 112 is provided at the bottom of the connecting groove 11, and a second through hole 541 is provided on the connecting bracket 54. A servo flange 113 is provided between the rotating shaft of the servo motor 521 and the bearing 111. The servo flange 113 passes through the first through hole 112 and the second through hole 541. The servo flange 113 is sleeved on the outside of the rotating shaft of the servo motor 521, and the bottom of the servo flange 113 abuts against the bearing 111. An end cap 14 is provided at the end of the servo flange 113 away from its bottom. The end cap 14 abuts against the connecting bracket 54, and the end cap 14 is fixedly connected to the rotating shaft of the servo motor 521. The servo flange 113 is connected between the shaft of the servo motor 521 and the connecting frame 54, so that the shaft of the servo motor 521 and the connecting frame 54 rotate synchronously. The end cover 14 further ensures the connection between the shaft of the servo motor 521 and the connecting frame 54, and also plays a role in sealing and preventing moisture, preventing dust and air from entering the interior of the servo flange 113 and affecting the rotation of the shaft of the servo motor 521.

[0034] The end cap 14 is connected to the shaft of the servo motor 521 by bolts (not shown in the figure), and the connection between the two is firm.

[0035] In this embodiment, three spraying components 5 are provided, arranged in a straight line. The three spraying components 5 can spray three workpieces simultaneously, improving the spraying efficiency of the workpieces.

[0036] A preferred embodiment of this utility model also provides a coating machine, including the spraying mechanism described in the above embodiment. The spray gun 53 of the coating machine can spray the workpiece from top to bottom and left to right, and can simultaneously cover the top and sides of the workpiece, resulting in good coating quality.
