Description

Technical Field

[0001] This application relates to the field of spraying equipment technology, and in particular to a multi-dimensional adjustable spraying equipment. Background Technology

[0002] In spray painting operations, the internal angles of workpieces (such as right angles, obtuse angles, and deep cavity internal angles) have always been a challenge due to their concealed structure and variable angles. Traditional spray painting equipment typically uses a fixed trajectory or manual adjustment of the spray gun angle, which presents the following problems:

[0003] 1. Poor adaptability: The internal angle dimensions and angles of different workpiece models vary greatly. Traditional equipment requires manual resetting of the spray gun position, angle and spraying parameters, which is time-consuming and prone to parameter mismatch due to human error.

[0004] 2. Many blind spots in spraying: It is difficult to accurately control the relative position of the spray gun and the inner corner by manual adjustment, which can easily lead to problems such as missed spraying and uneven coating thickness. In particular, traditional equipment cannot achieve full coverage spraying for deep cavity inner corners.

[0005] 3. Low efficiency: Each time a new workpiece model is changed, the machine needs to be stopped for parameter adjustment and equipment calibration, resulting in long downtime of the production line and low overall operation efficiency. Utility Model Content

[0006] To address the above problems, this application provides a multi-dimensional adjustable spraying device.

[0007] The multi-dimensional adjustable spraying equipment provided in this application adopts the following technical solution: A multi-dimensional adjustable spraying device, which can be installed in an operating room, is used to adjust the spray range of the spray gun, including: A movable outrigger, one end of which is connected to the control room; An adjustment assembly is connected to the support arm and the spray gun, respectively. The adjustment assembly includes a first adjustment member, a turntable, and a second adjustment member. The turntable is connected to the first adjustment member and to the spray gun through the second adjustment member. The adjustment assembly is configured to drive the spray gun to rotate when the first adjustment member is driven, and to adjust the spray angle and thickness of the spray gun when the second adjustment member is driven.

[0008] Furthermore, the first adjusting member includes a first bevel gear, a second bevel gear meshing with the first bevel gear, and a rotating rod connected to the first bevel gear, the rotating rod being connected to the turntable.

[0009] Furthermore, the first adjusting component also includes a second motor to provide power for the rotation of the second bevel gear.

[0010] Furthermore, the first adjusting member is disposed inside the housing, and the rotating rod passes through the housing and is connected to the turntable.

[0011] Furthermore, the second adjusting member includes a support column on the turntable, a first pulley and a second pulley on the support column, and a fixed seat connected to the first pulley. The fixed seat is connected to the spray gun, and the first pulley and the second pulley are connected to the same belt.

[0012] Furthermore, the second adjusting component also includes a first motor mounted on the turntable to provide power for the rotation of the second pulley.

[0013] Furthermore, the fixed seat is connected to the support via a shaft, the support is connected to the pillar, and the outwardly extending end of the shaft is connected to the first pulley.

[0014] Furthermore, the support arm is slidably connected to the first track via the second track, and the first track is perpendicular to the second track and connected to the operating room.

[0015] Furthermore, the paint inlet of the spray gun is connected to an external paint supply system via a high-pressure hose.

[0016] In summary, this application includes the following beneficial technical effects: The spray gun is driven to move along the X or Y axis by a movable support arm. The first adjustment component allows the spray gun to rotate around the Z axis, while the second adjustment component is responsible for adjusting the pitch angle of the spray gun in the X axis direction, thus achieving precise multi-degree-of-freedom adjustment of the spray gun in three-dimensional space. This design can adapt to the inner corners of workpieces with different angles and depths, effectively eliminating blind spots in spraying and ensuring full coverage of the inner corner areas.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a multi-dimensional adjustable spraying device, which can be installed in an operating room 1, for adjusting the spray range of the spray gun 7, including: The movable support arm 4 is connected to the operating chamber 1 at one end. The drive arm 4 slides relative to the operating chamber 1, enabling it to move along the X-axis or Y-axis of the operating chamber 1, thereby driving other components at the other end of the support arm 4 to move synchronously, thus quickly positioning the spray gun 7 near the position to be sprayed. The adjustment assembly is connected to the support arm 4 and the spray gun 7 respectively; The adjusting component includes a first adjusting component, a turntable 6, and a second adjusting component 10. The turntable 6 is connected to the first adjusting component and to the spray gun 7 through the second adjusting component 10. The adjusting component is configured to drive the spray gun 7 to rotate when the first adjusting component is driven, and to adjust the spray angle and spray thickness of the spray gun 7 when the second adjusting component 10 is driven.

[0021] The spray gun 7 is moved along the X or Y axis by a movable support arm 4. The position of the spray gun 7 is initially roughly adjusted, the first adjusting component rotates the spray gun 7 around the Z axis, and the second adjusting component 10 adjusts the pitch angle of the spray gun 7 along the X axis. This allows for precise adjustment of the spray gun 7 in three-dimensional space using multiple degrees of freedom. This application not only allows adjustment of the planar position of the spray gun 7 but also flexible adjustment of its spray angle to adapt to spraying targets of different shapes and sizes. In practical applications, operators can quickly move the spray gun 7 to the vicinity of the target area by controlling the movable support arm 4, and then make fine adjustments using the first and second adjusting components 10 to ensure that the spray gun 7 performs spraying operations at the optimal angle and position. This multi-dimensional adjustment method greatly improves the accuracy and efficiency of spraying, reducing waste and rework during the spraying process. Simultaneously, this design can adapt to the inner corners of workpieces with different angles and depths, effectively eliminating blind spots and ensuring full coverage of the inner corner areas.

[0022] As an alternative, the first adjusting component includes a first bevel gear 503, a second bevel gear 504 meshing with the first bevel gear 503, and a rotating rod 502 connected to the first bevel gear 503, the rotating rod 502 being connected to the turntable 6.

[0023] As an alternative, the first adjusting component also includes a second motor 501, which provides power for the rotation of the second bevel gear 504.

[0024] As an alternative, the first adjusting component is located inside the housing 5, and the rotating rod 502 passes through the housing 5 and is connected to the turntable 6.

[0025] As an alternative, the end of the rotating rod 502 away from the turntable 6 is rotatably connected to the inner wall of the housing 5 via a bearing.

[0026] Reference Figure 1 and Figure 3 The first adjusting component is installed inside the housing 5 and is used to drive the spray gun 7 to rotate around the Z-axis. The first adjusting component includes a rotating rod 502, which is vertically installed inside the housing 5. Its top end is connected to the turntable 6 via a bearing, and its bottom end is rotatably connected to the bottom surface of the housing 5 via a bearing, allowing it to rotate around its own axis. A first bevel gear 503 is fixedly sleeved on the middle of the outer wall of the rotating rod 502 and rotates synchronously with the rotating rod 502. A second motor 501 is fixedly installed on the inner side wall of the housing 5, and its output shaft end is fixedly sleeved with a second bevel gear 504 that meshes with the first bevel gear 503. When the second motor 501 operates, it drives the first bevel gear 503 to rotate through the second bevel gear 504, which in turn drives the rotating rod 502, which is fixedly connected to the first bevel gear 503, to rotate, thereby driving the turntable 6 to rotate around the Z-axis. Therefore, it can drive other components installed on the turntable 6 to rotate around the Z-axis, that is, drive the spray gun 7 to rotate.

[0027] As an alternative, the second adjusting component includes a support column 105 on the turntable 6, a first pulley 104 and a second pulley 107 on the support column 105, and a fixed seat 101 connected to the first pulley 104. The fixed seat 101 is connected to the spray gun 7, and the first pulley 104 and the second pulley 107 are connected to the same belt.

[0028] As an alternative, the second adjustment component also includes a first motor 106 mounted on the turntable 6 to provide power for the rotation of the second pulley 107.

[0029] As an alternative, the fixed base 101 is connected to the support 102 via the shaft 103, the support 102 is connected to the column 105, and the outwardly extending end of the shaft 103 is connected to the first pulley 104.

[0030] As an optional configuration, the outrigger 4 is slidably connected to track 2 via track 3, with track 2 perpendicular to track 3 and connected to the operator's cab 1. (Refer to...) Figure 1As shown, two sets of rails 1-2 are installed parallel to each other on the mounting base plate on the inner wall of the operating chamber 1, extending in the X-axis direction, forming a parallel guide rail structure between the two sets of rails 1-2. Rail 2-3 is slidably connected between the two sets of rails 1-2, extending in the Y-axis direction. Rail 2-3 can slide along the X-axis direction of rails 1-2 and can drive the support arm 4 to move along the Y-axis direction. One end of the support arm 4 is connected to the housing 5 through a flange, and the other end is inserted into rail 2-3 and can move up and down along rail 2-3 (i.e., along the Y-axis direction), thereby driving other components to move along the Y-axis direction. Rail 2-3 moves left and right relative to rails 1-2, thereby driving the support arm 4 and other components on the support arm 4 to move along the X-axis direction. In this embodiment, both rails 1-2 and rail 2-3 adopt ball screw linear modules, whose drive motors are servo motors, and are used in conjunction with grating rulers for position feedback, thereby ensuring the accuracy of the spray gun 7 position adjustment. Ball screw linear modules are existing technology, which those skilled in the art can understand, so they will not be described in detail here.

[0031] As an alternative, the paint inlet of the spray gun 7 is connected to an external paint supply system via a high-pressure hose.

[0032] Reference Figure 1 and Figure 2 The second adjusting component 10 is installed on the top surface of the turntable 6. Since the turntable 6 is fixedly connected to the rotating rod 502, the rotating rod 502 can drive the turntable 6 and its related components to rotate around the Z-axis. The second adjusting component 10 is used to drive the pitch angle adjustment of the spray gun 7. The second adjusting component 10 includes a support column 105, which is fixed to the center of the top surface of the turntable 6. The top of the support column 105 is fixedly connected to the support 102. The support 102 has a U-shaped structure, and its two side walls are provided with coaxial shaft holes. The fixed seat 101 has a block structure, and its two sides are provided with shafts 103 that are adapted to the shaft holes of the support 102. The fixed seat 101 is rotatably connected to the support 102 through the shafts 103. The first motor 106 is fixedly installed on one side of the top surface of the turntable 6. The output shaft end is fixedly sleeved with a second pulley 107 to provide power for the rotation of the second pulley 107. One end of the shaft 103 passes through the side wall of the support 102 and extends outward. The extended end is fixedly fitted with a first pulley 104. The first pulley 104 and the second pulley 107 are connected by a synchronous belt drive. When the first motor 106 is running, its output end drives the second pulley 107 to rotate. The second pulley 107 drives the shaft 103 to rotate through the belt drive, thereby driving the fixed base 101 to pitch around the shaft 103 (X-axis).

[0033] The wrap angle of the first pulley 104 and the second pulley 107 ensures that the belt drive does not slip, so that the speed of the first motor 106 can be accurately converted into the rotation angle of the shaft 103, thereby realizing the precise control of the pitch angle of the spray gun 7. The wrap angle range matches the adjustment range of the spray gun 7, ensuring that the belt always remains stable and close during the pitch adjustment process, without transmission interruption, thus improving the continuity and consistency of the spraying operation.

[0034] Reference Figures 1-3 The housing 5 is a hollow box structure, with its sides fixedly connected to the support arm 4 via connecting flanges. The interior houses the first adjusting component, providing protection and support. The turntable 6 is a circular flat plate structure, with its bottom surface fixedly connected to the top of the rotating rod 502 of the rotation angle adjusting assembly. The spray gun 7 is fixedly mounted on the fixing seat 101 of the second adjusting component 10. The nozzle of the spray gun 7 faces the inner corner of the workpiece, and the paint inlet of the spray gun 7 is connected to an external paint supply system via a high-pressure hose. The paint supply is regulated by a flow valve controlled by the main control module. By adjusting the flow rate and precise position of the spray gun 7, uniform spraying of different workpiece inner corners can be achieved, meeting diverse spraying needs.

[0035] Finally, it should be clarified that the multi-dimensional adjustable spraying equipment involved in this utility model is mainly used to adjust the spray range of the spray gun 7, and it is compatible with the spraying equipment and the operating room 1. It is particularly important to note that this solution does not limit the specific structure, manufacturer, or model of the following electrical control components. Any existing electrical control components that can meet the requirements for the spray range of the spray gun 7 can be used.

[0036] The application of electronic control components will significantly improve automation efficiency based on this design. For example, a barcode scanner 8 can be installed near the nozzle of the spray gun 7, with its scanning direction aligned with the nozzle orientation. This scanner scans the barcode on the workpiece surface, reads key information such as workpiece model, internal angle dimensions, and material, and transmits the data to the main control module. An angle sensor 9 is placed at the connection between the spray gun 7 and the mounting base 101 to monitor the rotation angle of the spray gun 7 around the Z-axis and the pitch angle around the X-axis in real time. The angle data is converted into electrical signals and transmitted to the main control module. Furthermore, a small camera is installed next to the barcode scanner 8 to capture images of the spraying process in real time. These images are transmitted to the main control module for video monitoring to identify issues such as missed spraying and paint accumulation. The data storage module is electrically connected to the main control module and stores two types of data: a basic workpiece database containing information such as internal angle dimensions, material, and surface treatment requirements for different workpiece models; and a spraying parameter library covering parameters such as spraying pressure, paint flow rate, spray gun 7 moving speed, and distance between the spray gun 7 and the workpiece for each workpiece model, forming a mapping relationship between workpiece model and spraying parameters, supporting rapid retrieval. Based on the technical solution of this application, it can effectively help users further improve work efficiency and automation.
