[0001] This utility model relates to a spraying device and belongs to the technical field of spraying equipment. Background Technology

[0002] In industrial production, the traditional method for spraying various machine casings and other workpieces often relies on manual operation of spray guns, which is not only inefficient but also makes it difficult to ensure the uniformity and consistency of the coating. With the development of automation technology, spraying equipment has emerged.

[0003] For example, Chinese utility model patent CN222057776U discloses a CNC spraying device, including: a machine body, a first motor fixedly connected to the inner surface of the machine body, a lead screw fixedly connected to the output end of the first motor, a slider threadedly connected to the outer surface of the lead screw, a second motor fixedly connected to the outer surface of the slider, a rotating plate fixedly connected to the output end of the second motor, a third motor fixedly connected to the lower surface of the rotating plate, and a turntable fixedly connected to the output end of the third motor.

[0004] The above solution has the following shortcomings in practical use:

[0005] This solution reduces the amount of paint particles scattered in the air by adjusting the height and angle of the spray head and drawing in paint particles sprayed into the air. However, in actual use, when the workpiece is large, it needs to be rotated manually. Moreover, the above structure can only spray one workpiece at a time, resulting in low spraying efficiency. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] like Figure 1 As shown, a spraying device includes a spray booth 100, which serves as the housing space for the entire device, reducing the pollution of the work area caused by paint mist diffusion. The spray booth 100 is equipped with a spraying unit 400 and a drive unit 300 for moving the spraying unit 400. A support unit 500 for fixing the workpiece is provided at the bottom of the spray booth 100. The movement of the spraying unit 400 by the drive unit 300 enables the spraying unit 400 to move precisely and flexibly in three-dimensional space. Combined with the large rotation range of the spraying unit 400, it ensures that there are no dead angles for spraying workpieces with complex shapes, greatly improving the spraying quality and efficiency.

[0026] Furthermore, a spray booth base 200 is provided on one side of the bottom of the inner wall of the spray booth 100.

[0027] like Figure 2As shown, the drive unit 300 includes a mounting bracket 301, which provides the mounting foundation for the entire drive structure, ensuring its stable installation within the spray booth. An X-axis rail 302 is mounted on the top of the mounting bracket 301. A mounting seat 305 and an actuator 304 that drives the longitudinal movement of the mounting seat 305 are mounted on the X-axis rail 302. The actuator 304 drives the mounting seat 305 to move along the length of the X-axis rail 302, achieving initial horizontal and longitudinal positioning of the spraying unit. Two mounting seats 305... The 05 is equipped with a Y-axis track 303, a Z-axis guide rail 306 and an actuator 307 for driving the Z-axis guide rail 306 to move laterally. The actuator 307 drives the Z-axis guide rail 306 to move along the length of the Y-axis track 303, further refining the planar positioning of the spraying unit. The Z-axis guide rail 306 is equipped with an actuator 308 for driving the spraying unit 400 to move up and down. With the cooperation of the above structures, the spraying unit 400 can move accurately and flexibly in three-dimensional space.

[0028] like Figure 3 As shown, the spraying unit 400 includes a wrist column 401, with a gun shaft 402 rotatably connected to the bottom end of the wrist column 401. Spray guns 403 are provided at both ends of the gun shaft 402. An actuator 404 is provided on the wrist column 401 to drive the gun shaft 402 to rotate. The rotation angle range of the gun shaft 402 is 0-270°. By driving the gun shaft 402 to rotate through the actuator 404, the spraying range of the spray guns 403 can be adjusted, realizing spraying without dead angles on the surface of complex-shaped workpieces, which greatly improves the uniformity and integrity of the spraying.

[0029] like Figure 4 and Figure 5 As shown, the support unit 500 includes a column 501. The top of the column 501 is connected to a connecting plate 503 via a main shaft 502. The connecting plate 503 serves as a transition connection. A protective plate 504 is provided on the top of the connecting plate 503. The protective plate 504 provides a certain degree of protection for internal components, preventing impurities such as paint mist from entering critical parts. Each end of the protective plate 504 is provided with a support plate 505. The support plate 505 is provided with a housing flange 506 and two housing flanges 507, as well as an execution unit for driving the housing flange 506 and the two housing flanges 507 to rotate. With the cooperation of the above structure, it can flexibly handle housings of different sizes. When facing multiple small housings to be painted, they can be fixed by housing flanges 506 and 507 respectively. For larger housings, the stability of the housing during the painting process can be ensured by adjusting the combination and fixing method of the flanges.

[0030] Furthermore, a cylinder 508 is provided on the top of the column 501, and a rack fixing plate 509 is provided at the output end of the cylinder 508. A rack 510 is provided on the side of the rack fixing plate 509 near the main shaft 502. A gear 511 is provided on the main shaft 502. The gear 511 meshes with the rack 510. The extension and retraction of the cylinder 508 drives the rack 510 to move, thereby driving the gear 511 to rotate, realizing the rotation of the main shaft 502 and the guard plate 504 connected to it. This allows for flexible adjustment of the workpiece angle during the spraying process, further ensuring that all surfaces of the workpiece are uniformly sprayed.

[0031] It should be noted that, in this embodiment, actuator 304 includes a motor, a transmission wheel, and a transmission belt. The motor drives the transmission wheel to rotate and move the transmission belt. Part of the transmission belt is connected to the mounting base 305. Actuators 307 and 308 use the same driving method as actuator 304. The actuator unit includes a motor, a synchronous belt, and three synchronous pulleys. The three synchronous pulleys are respectively connected to housing flange 506 and two housing flanges 507 via shafts. The motor drives one of the synchronous pulleys to rotate, and the three synchronous pulleys rotate under the transmission of the synchronous belt. Actuator 404 includes a motor, a synchronous belt, and two synchronous pulleys. The synchronous pulleys are respectively connected to the output shaft of the motor and the gun shaft 402. The synchronous belt is sleeved on the two synchronous pulleys.

[0032] The workflow of this embodiment is as follows: The housing to be painted is placed on the support plate 505 of the support unit 500. Appropriate housing flange one 506 and housing flange two 507 are selected according to the housing size for fixing. According to the painting process requirements, actuator one 304 in the drive unit 300 is activated, driving the mounting base 305 to move on the X-axis track 302, initially positioning the longitudinal position of the painting unit 400. Then, actuator two 307 drives the Z-axis guide rail 306 to move laterally on the Y-axis track 303, precisely adjusting the painting process. Unit planar position; finally, actuator 308 drives the spraying unit 400 to move up and down to a suitable height. Actuator 404 of the spraying unit 400 drives the gun shaft 402 to rotate within the range of 0-270° as needed, adjusting the angle of the spray gun 403. During the spraying process, if it is necessary to adjust the angle of the workpiece, the cylinder 508 is started, and through the meshing transmission of the rack 510 and the gear 511, the main shaft 502 is driven to rotate, thereby changing the orientation of the workpiece to ensure a comprehensive and uniform spraying effect until the spraying operation of the entire machine casing is completed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
