Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] Research has revealed that in related technologies, when using a robotic arm for spraying, the spray gun on the robotic arm is fixed, requiring constant adjustment of the spraying angle by moving the workpiece. This results in some hidden areas of the workpiece not being sprayed, making it difficult to achieve multi-angle, all-around spraying and affecting the uniformity of the coating, thus impacting the overall coating effect. If the object being operated is replaced with a spray gun, the problem of pipe tangling due to the movement of the spray gun arises. During the painting process, if the paint pipe folds, the paint supply to the spray gun cannot be normal, hindering proper spraying and also affecting the coating effect. Based on this, this application provides a comprehensive and efficient multi-angle spraying device 1.

[0032] See Figure 1 , Figure 1 A schematic diagram of a multi-angle spraying device 1 according to an embodiment of this application is shown. The multi-angle spraying device 1 provided in this embodiment includes a housing 100, a material conveying mechanism 500, a spray gun 400, a drive mechanism 200, and a transmission mechanism 300. The material conveying mechanism 500 is disposed within the housing 100 and is used to provide spraying material. The spray gun 400 is disposed within the housing 100 and is connected to the material conveying mechanism 500 via a conveying pipe 501. The drive mechanism 200 is connected to the housing 100 and is configured to drive the spray gun 400 to move at least along a first direction X, thereby spraying the workpiece from multiple angles. The transmission mechanism 300 is drively connected to the drive mechanism 200 and includes a first transmission component 310 and a second transmission component 320. The first transmission assembly 310 is configured to drively connect the spray gun 400 and the drive mechanism 200, and the second transmission assembly 320 is configured to adjust the delivery pipe 501 so that the delivery pipe 501 cooperates with the movement of the spray gun 400. While transmitting the driving force of the drive mechanism 200, the first transmission assembly 310 and the second transmission assembly 320 can also adjust and regulate the delivery pipe 501 through transmission or follow-up.

[0033] The housing 100 is divided along the second direction Y into parallel spraying chambers 120 and accommodating chambers 110. Spraying chambers 120 are used to complete the workpiece spraying process, and accommodating chambers 110 are used to accommodate most of the multi-angle spraying device 1. Specifically, as shown... Figure 1 As shown, the second direction Y is the height direction of the multi-angle spraying device 1, and the first direction X is the length direction of the multi-angle spraying device 1. The spraying cavity 120 is located above the receiving cavity 110. The size of the receiving cavity 110 in the second direction Y or other directions can be larger than the size of the spraying cavity 120. The first direction X is perpendicular to the second direction Y.

[0034] In some embodiments, the first transmission assembly 310 includes a first screw 311 and a mounting bracket 312. The first screw 311 is connected to the housing 100 along the first direction X and is drive-connected to the drive mechanism 200. The mounting bracket 312 is drive-connected to the first screw 311 and is capable of moving relative to the first screw 311 along the first direction X. The spray gun 400 is disposed on the mounting bracket 312. By configuring the first screw 311 and the mounting bracket 312, the spray gun 400 is ensured to move along the first direction X, thereby increasing the coverage effect of the spray gun 400 on the surfaces of the workpiece during operation.

[0035] The first screw 311 is disposed at the top of the spraying cavity 120, the driving mechanism 200 is disposed on the housing 100 at a position corresponding to the receiving cavity 110, and the transmission mechanism 300 further includes a first transmission member 313 that drives the driving mechanism 200 and the first screw 311 to be connected, and the first transmission member 313 is disposed along the second direction Y.

[0036] Furthermore, the drive mechanism 200 is fixedly disposed on one side of the housing 100. In some embodiments, the drive mechanism 200 can be one of an electric drive, a hydraulic drive, or a pneumatic drive. An electric drive refers to a drive device that uses electricity to provide power, and can include an electric motor, an electric actuator, etc. A hydraulic drive utilizes the force of liquid to transmit power and generate motion. A hydraulic drive can be a hydraulic pump, a hydraulic cylinder, a hydraulic motor, etc. A pneumatic drive utilizes the force of gas to transmit power and generate motion. A pneumatic drive can be a pneumatic cylinder, a pneumatic motor, a pneumatic valve, etc. It is understood that a suitable drive needs to be selected according to specific requirements to achieve the required motion power and control function. In this embodiment, the drive mechanism 200 is a motor, and the output shaft of the drive mechanism 200 has rotational motion, and the output shaft is disposed inside the housing 100.

[0037] The first transmission assembly 310 further includes a first transmission member 313. The output shaft of the drive mechanism 200 is connected to a first pulley 201, and one end of the first screw 311 is provided with a second pulley 314. The first pulley 201 and the second pulley 314 are connected by the first transmission member 313. In this embodiment, the first transmission member 313 is a transmission belt sleeved on the first pulley 201 and the second pulley 314 and extending along the second direction Y. The first pulley 201, the first transmission member 313, and the second pulley 314 of the drive mechanism 200 drive the first screw 311 to rotate about a straight line parallel to the first direction X. The speed ratio can be adjusted by adjusting the diameters of the first pulley 201 and the second pulley 314.

[0038] The first screw 311 has a threaded surface, and the mounting bracket 312 has a thread that connects to the threaded surface, so that the mounting bracket 312 and the first screw 311 are connected in a driving manner. When the first screw 311 rotates, the mounting bracket 312 can move along the first direction X. Furthermore, by changing the rotation direction of the first screw 311, the movement of the mounting bracket 312 along the first direction X or in a direction opposite to the first direction X can be changed.

[0039] The spray gun 400 is connected to the mounting bracket 312 via a motion unit 315. A drive mechanism 200 is connected to the motion unit 315, which is configured to move the spray gun 400 relative to the mounting bracket 312 in at least three directions different from the first direction X. By providing the motion unit 315, the spray gun 400 is improved. In this embodiment, the motion unit 315 is a robotic arm; preferably, it is a six-axis robotic arm, which allows the spray gun 400 to have six degrees of freedom, enabling omnidirectional spraying of the workpiece.

[0040] In some embodiments, the second transmission assembly 320 includes a second screw 321 and a moving block 322, and a limiting block 323 is provided on the housing 100. The second screw 321 is disposed within the housing 100 along the first direction X and is tractively connected to the drive mechanism 200. The conveying pipe 501 is wound between the limiting block 323 and the moving block 322. The moving block 322 is tractively connected to the second screw 321 and can move relative to the second screw 321 along the first direction X to drive the conveying pipe 501 to move relative to the limiting block 323. When the spray gun 400 moves, the second transmission assembly 320 can adjust the extension shape and position of the conveying pipe 501 by movement to prevent the conveying pipe 501 from folding when the spray gun 400 moves, thereby improving the spraying effect of the spray gun 400 on the workpiece.

[0041] The second screw 321 has a threaded surface, and the moving block 322 has a thread that connects to the threaded surface, so that the moving block 322 and the second screw 321 are connected in a transmission manner. When the second screw 321 rotates, the moving block 322 can move along the first direction X. Furthermore, by changing the rotation direction of the second screw 321, the movement of the moving block 322 along the first direction X or in a direction opposite to the first direction X can be changed.

[0042] Multiple limiting blocks 323 are provided, and multiple limiting blocks 323 are fixedly connected to the inner surface of the housing 100. Multiple limiting blocks 323 can limit the main extension path of the conveying pipe 501 and the movement range of the conveying pipe 501. When the moving block 322 drives part or the whole of the conveying pipe 501 to move, the fixed limiting blocks 323 support part of the conveying pipe 501 to extend along the preset path. The moving block 322 and the limiting blocks 323 cooperate with each other to prevent the conveying pipe 501 from folding or getting tangled.

[0043] Furthermore, a raw material conveying mechanism 500 is disposed in the receiving cavity 110, and a conveying pipe 501 extends from the receiving cavity 110 to the spraying cavity 120. A second screw 321 is disposed in the receiving cavity 110 along the first direction X. A raw material pump is also provided on the conveying pipe 501, which is used to draw the spraying material from the raw material conveying mechanism 500 and convey it to the spray gun 400.

[0044] In some embodiments, the raw material conveying mechanism 500 includes a raw material storage tank 510 and a stirring paddle 520 disposed in the raw material storage tank 510, and the transmission mechanism 300 further includes a third transmission assembly 330. The raw material storage tank 510 is configured to contain the spraying material, and the stirring paddle 520 is driveably connected to the third transmission assembly 330. The third transmission assembly 330 is configured to drively connect to the drive mechanism 200 to drive the stirring paddle 520 to move, thereby fully mixing the spraying material. One end of the stirring paddle 520 extends out of the raw material storage tank 510 and is drively connected to the third transmission assembly 330, while the other end is provided with stirring paddle blades and located inside the raw material storage tank 510.

[0045] In some embodiments, such as Figure 4 As shown, the raw material conveying mechanism 500 and the second transmission assembly 320 are arranged side-by-side in the receiving cavity 110. The drive mechanism 200 is located close to the raw material conveying mechanism 500, which is situated between the second transmission assembly 320 and the drive mechanism 200. To transmit the motion output from the drive mechanism 200 to the more distant second transmission assembly 320, a second transmission member 331 is provided between the output shaft of the second transmission assembly 320 and the drive mechanism 200. The second transmission member 331 is a transmission rod, and it is connected to one end of the second screw 321 in the second transmission assembly 320. The second transmission member 331 extends above the raw material conveying mechanism 500 and is connected to the second transmission assembly 320. Figure 3 As shown, when the second transmission member 331 and the second screw 321 are not at the same height in the second direction Y, a transmission belt extending along the second direction Y can be provided between the second transmission member 331 and the second screw 321, and pulleys connecting the transmission belt are provided at the corresponding ends of the second transmission member 331 and the second screw 321, and the transmission belt and pulleys drive and connect the two.

[0046] Furthermore, the third transmission assembly 330 includes the second transmission member 331, a first bevel gear 332 mounted on the second transmission member 331, and a second bevel gear 333 meshing with the first bevel gear 332. The drive mechanism 200 drives the second transmission member 331 to rotate, and the first bevel gear 332 mounted on the second transmission member 331 rotates with the second transmission member 331. The second bevel gear 333 is located at one end of the stirring paddle 520 extending from the raw material storage tank 510. Through the second bevel gear 333 meshing with the first bevel gear 332, the stirring paddle 520 is driven to rotate, thus mixing the raw materials. By setting up a drive mechanism 200 and configuring the transmission assembly, the mixing of raw materials, the driving of the spray gun 400, and the arrangement of the conveying pipe 501 can be realized. The structure is precise and saves power.

[0047] In some embodiments, the multi-angle spraying device 1 further includes a odor removal mechanism 600, which includes a blower 610, a piston assembly 620, and a suction pipe 640. The blower 610 has a piston chamber, and the suction pipe 640 communicates with the piston chamber. The piston assembly 620 is disposed in the piston chamber. The piston assembly 620 is throttle-connected to the transmission mechanism 300, and moves within the piston chamber under the action of the transmission mechanism 300. The movement of the piston assembly 620 within the blower 610 generates negative pressure, which adsorbs and discharges odors generated during painting through the suction pipe 640 into the spraying chamber 120. The inlets of the spray gun 400 and the suction pipe 640 are spaced apart within the spraying chamber 120, meaning that the inlet of the suction pipe 640 is not located in the movement path of the spray gun 400.

[0048] A deodorization mechanism 600 is disposed within the receiving cavity 110. Specifically, the deodorization mechanism 600 is disposed in the gap between the second transmission assembly 320 and the raw material conveying mechanism 500. The suction pipe 640 extends from the receiving cavity 110 to the spraying cavity 120. The deodorization mechanism 600 also includes a neutralization box 630, which is connected to the air duct 610 via a pipeline to neutralize the intake gas. The neutralized portion of the usable raw material can be returned to the raw material storage tank 510. Furthermore, the air duct 610 is connected to the suction pipe 640 on one side and the neutralization box 630 on the other side.

[0049] In some embodiments, the transmission mechanism 300 further includes a fourth transmission assembly 340 capable of drivingly connecting the piston assembly 620 and the drive mechanism 200. The fourth transmission assembly 340 is drivenly connected to the drive mechanism 200 via the second transmission assembly 320. The piston assembly 620 includes a push plate and a piston rod. The push rod is disposed around the inner wall of the air duct 610, and the piston rod is connected to the push plate and extends out of the air duct 610 to connect with the fourth transmission assembly 340.

[0050] For further details, please refer to [link / reference]. Figure 5 , Figure 5 This diagram illustrates a partial structure of the fourth transmission assembly 340 and the removal mechanism 600 in one embodiment of this application. The fourth transmission assembly 340 includes a third transmission member 341, a rotating wheel 342, a round shaft 343, and a grooved plate. The third transmission member 341 drives the second transmission member 331 or the second transmission assembly 320 to the rotating wheel 342. Specifically, the third transmission member 341 is a transmission belt that is respectively sleeved at both ends on the second transmission member 331 and the second screw 321 and extends along the second direction Y on the rotating wheel 342. The round shaft 343 is provided at an eccentric position on the rotating wheel 342. The grooved plate 344 is slidably connected to the housing 100 and fixedly connected to the piston rod of the piston assembly 620. The grooved plate 344 is provided with a movement groove, and the round shaft 343 is disposed in the movement groove and slidably connected to the grooved plate 344. When the rotating wheel 342 rotates around its central axis, the circular shaft 343 follows the rotating wheel 342 and rotates around its central axis. The groove plate 344 is driven to slide along a preset axis, driving the piston assembly 620 to perform piston movement in the air duct 610. By setting a drive mechanism 200 and configuring a transmission component, it is possible to mix raw materials, drive the spray gun 400 to move, straighten the conveying pipe 501, and perform de-pollination treatment. The structure is precise and saves power.

[0051] In some embodiments, the second transmission assembly 320, the third transmission assembly 330, and the fourth transmission assembly 340 are at least partially disposed in the mounting cavity and at least partially fixedly connected between the raw material storage tank 510 and the housing 100. Specifically, the second transmission member 331, the rotating wheel 342, the second screw 321, and other structures can be fixedly disposed at corresponding positions on the outer surface of the raw material storage tank 510 to save structural space.

[0052] In some embodiments, see Figure 2 , Figure 2 The diagram shows a structural schematic of the housing 100 in one embodiment of this application. The housing 100 is provided with an inspection door at the location of the housing cavity. The inspection door can selectively seal the housing cavity or allow the housing cavity to communicate with the outside, which facilitates maintenance by operators.

[0053] In some embodiments, a heater and a temperature sensor (not shown) are provided inside the raw material storage tank 510, and a controller is provided on the raw material storage tank 510. Both the heater and the temperature sensor are electrically connected to the controller. When the coating material is added to the raw material storage tank 510, if the sensor detects a temperature lower than a preset value before spraying, the controller activates the heater to heat the coating material. Once the temperature reaches the preset value, the heater stops heating and maintains a constant temperature to ensure the coating material remains within the preset value. Specifically, the preset value can be a certain range, determined based on the optimal temperature of the coating material. By providing a heater, a temperature sensor, and a controller, the material's fluidity is prevented from deteriorating due to excessively low temperature, thus ensuring the spraying effect of the multi-angle spraying device 1.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
