Description

Technical Field

[0001] This utility model relates to the field of spraying robot technology, and in particular to an industrial spraying robot. Background Technology

[0002] In modern industrial production, spraying is a crucial step in surface treatment and is widely used in various fields such as automobile manufacturing, machining, and furniture production. Its quality directly affects the appearance, corrosion resistance, and service life of products. With the acceleration of industrialization and the development of automation technology, traditional manual spraying methods are gradually failing to meet the demands for efficient, precise, and environmentally friendly production.

[0003] While the painting robots currently on the market have improved in terms of automation, there are still some technical pain points: the painting mechanism of some robots is not flexible enough and can only achieve adjustment in a single direction or a limited angle. For workpieces with complex structures such as curved surfaces and irregular shapes, it is difficult to achieve all-round, no-dead-angle painting; some robots are also inconvenient to move as a whole and cannot adapt to the layout changes of different production sites or production lines, which limits their application scope.

[0004] To address these issues, we designed an industrial painting robot aimed at solving the technical problems of existing painting robots. Utility Model Content

[0005] This utility model discloses an industrial spraying robot. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] An industrial spraying robot includes an arc-shaped base, a robot body fixedly mounted on the upper surface of the arc-shaped base, an extension arm with a hollow shell fixedly mounted on the top of the robot body, and a rotary spraying mechanism mounted on the surface of the extension arm.

[0007] The rotary spraying mechanism includes a movable sleeve rotatably disposed on the lower surface of an extension arm. A rotary movable arm is fixedly connected to the bottom end of the movable sleeve. A strip-shaped limiting shell is fixedly connected to the lower surface of the rotary movable arm. A horizontal threaded rod is rotatably connected to the inner wall of the strip-shaped limiting shell. A movable frame is threadedly connected to the surface of the horizontal threaded rod. A guide frame is fixedly connected to the side of the movable frame. A lifting screw is rotatably connected to the inner side of the guide frame. A lifting block is threadedly connected to the surface of the lifting screw. Fixed plates are fixedly connected to both sides of the lifting block. A paint spray head is fixedly installed at one end of each of the two fixed plates.

[0008] In a preferred embodiment, a lifting motor is fixedly connected to the bottom end of the guide frame, and the rotating shaft of the lifting motor extends into the interior of the guide frame and is fixedly connected to the bottom end of the lifting screw.

[0009] In a preferred embodiment, a horizontal motor is fixedly connected to one end of the strip-shaped limiting shell, and the rotating shaft of the horizontal motor extends into the interior of the strip-shaped limiting shell and is fixedly connected to one end of the horizontal threaded rod.

[0010] In a preferred embodiment, the top of the robot body is provided with a mounting groove, and a drive motor is fixedly connected to the inner wall of the mounting groove. The rotation shaft of the drive motor extends into the interior of the extension arm and is fixedly connected to a drive shaft rod. A drive bevel gear is fixedly connected to the end of the drive shaft rod away from the drive motor.

[0011] In a preferred embodiment, the top end of the movable sleeve is rotatably connected to the lower surface of the extension arm via a bearing, and the top end of the movable sleeve extends into the interior of the extension arm. A driven bevel gear ring is fixedly connected to the top end of the movable sleeve. The position of the driven bevel gear ring corresponds to that of the driving bevel gear, and the driving bevel gear meshes with the driven bevel gear ring.

[0012] In a preferred embodiment, a paint delivery pump is fixedly mounted on the upper surface of the extension arm, and a paint delivery pipe is fixedly connected to the output end of the paint delivery pump. The end of the paint delivery pipe away from the paint delivery pump extends into the interior of the movable sleeve, and the paint delivery pipe and the movable sleeve are coaxial with each other.

[0013] In a preferred embodiment, the bottom end of the paint delivery pipe extends below the rotating movable arm, and the paint delivery pipe is rotatably connected to the lower surface of the rotating movable arm via a bearing. A rubber hose is fixedly connected to the output end of the paint delivery pipe, and the end of the rubber hose away from the paint delivery pipe is fixedly connected to the input end of the paint nozzle.

[0014] In a preferred embodiment, two omnidirectional wheels are fixedly installed at the front bottom of the arc-shaped base, and a movable wheel is fixedly installed at the bottom of the robot body.

[0015] As can be seen from the above, the industrial painting robot provided by this utility model has the following technical effects.

[0016] 1. By setting up a rotating spraying mechanism, 360° directional adjustment can be achieved, with a wide spraying range and high flexibility. The horizontal motor drives the horizontal threaded rod to rotate, so that the moving frame drives the guide frame and paint nozzle to move in the horizontal direction, and the spraying radius can be adjusted according to the spraying object.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 An industrial spraying robot, the overall structure from bottom to top includes an arc-shaped base 1, a robot body 2, an extension arm 3 and a rotating spraying mechanism 4, and is equipped with casters 5 and movable wheels 6 to achieve overall movement.

[0026] The arc-shaped base 1 serves as the basic support component for the entire robot. Two omnidirectional wheels 5 are fixedly installed at the bottom front of the base, while the robot body 2 has casters 6 fixedly installed at its bottom. The omnidirectional wheels 5 allow for flexible adjustment of the robot's steering, while the casters 6 provide the main power for movement. Together, they enable the robot to freely adjust its working position according to operational needs, allowing it to quickly adapt to both small production sites and large assembly lines, greatly improving the equipment's site adaptability.

[0027] The robot body 2 is fixedly mounted on the upper surface of the arc-shaped base 1. The robot body 2 serves as the core load-bearing component, and an extension arm 3 is fixedly mounted on its top. The extension arm 3 is a hollow shell structure, which provides a mounting base for the rotary spraying mechanism 4 and also reserves space for internal transmission components. The rotary spraying mechanism 4 is mounted on the surface of the extension arm 3.

[0028] It is worth noting that the movable sleeve 401 of the rotary spraying mechanism 4 is rotatably mounted on the lower surface of the extension arm 3, and its top end is rotatably connected to the lower surface of the extension arm 3 through a bearing. The top end of the movable sleeve 401 extends upward into the interior of the extension arm 3. A driven bevel gear ring 417 is fixedly connected to the top end of the movable sleeve 401, which forms a transmission engagement with the drive component in the mounting slot at the top end of the robot body 2.

[0029] The top of the robot body 2 is provided with a mounting groove. A drive motor 414 is fixedly connected to the inner wall of the mounting groove. The rotation shaft of the drive motor 414 extends into the interior of the extension arm 3 and is fixedly connected to a drive shaft 415. A drive bevel gear 416 is fixedly connected to the end of the drive shaft 415 away from the drive motor 414. The position of the drive bevel gear 416 corresponds to the driven bevel gear ring 417, and the two mesh with each other.

[0030] When the drive motor 414 starts, its rotating shaft drives the drive bevel gear 416 to rotate via the drive shaft rod 415. The drive bevel gear 416 then drives the movable sleeve 401 to rotate around the lower surface of the extension arm 3 through meshing with the driven bevel gear ring 417, thereby enabling the entire rotary spraying mechanism 4 to achieve 360° directional adjustment. This bevel gear meshing transmission method not only provides stable transmission but also allows for flexible direction switching, enabling the paint nozzle 411 to cover all sides of the workpiece, significantly improving the flexibility and range of spraying.

[0031] It is worth noting that a rotating movable arm 402 is fixedly connected to the bottom end of the movable sleeve 401, and a strip-shaped limiting shell 403 is fixedly connected to the lower surface of the rotating movable arm 402. A horizontal threaded rod 405 is rotatably connected to the inner wall of the strip-shaped limiting shell 403. One end of the horizontal threaded rod 405 is connected to a horizontal motor 404 fixed to one end of the strip-shaped limiting shell 403. The rotating shaft of the horizontal motor 404 extends into the interior of the strip-shaped limiting shell 403 and is fixedly connected to one end of the horizontal threaded rod 405.

[0032] A movable frame 406 is threadedly connected to the surface of the horizontal threaded rod 405, and a guide frame 407 is fixedly connected to the side of the movable frame 406. When the horizontal motor 404 starts, its rotating shaft drives the horizontal threaded rod 405 to rotate within the strip-shaped limiting shell 403. Because the movable frame 406 is threadedly connected to the horizontal threaded rod 405 and is limited by the strip-shaped limiting shell 403, the movable frame 406 will move horizontally along the axial direction of the horizontal threaded rod 405, thereby driving the guide frame 407 and subsequent components to move horizontally synchronously. This design allows for flexible adjustment of the horizontal position of the paint nozzle 411 according to the size of the object being sprayed, expanding the horizontal spraying coverage of a single unit of equipment, and enabling large-area spraying operations to be completed without frequent movement of the entire robot.

[0033] It is worth noting that a lifting screw 408 is rotatably connected to the inner side of the guide frame 407, and a lifting motor 412 is fixedly connected to the bottom end of the guide frame 407. The rotation shaft of the lifting motor 412 extends into the interior of the guide frame 407 and is fixedly connected to the bottom end of the lifting screw 408. A lifting block 409 is threadedly connected to the surface of the lifting screw 408, and fixing plates 410 are fixedly connected to both sides of the lifting block 409. A paint spray head 411 is fixedly installed at one end of both fixing plates 410.

[0034] When the lifting motor 412 starts, its rotating shaft drives the lifting screw 408 to rotate within the guide frame 407. Under the action of the screw thread and the limiting action of the guide frame 407, the lifting block 409 moves vertically up and down along the axis of the lifting screw 408, which in turn drives the paint nozzle 411 to move up and down synchronously through the fixing plate 410. This structure allows the paint nozzle 411 to accurately adapt to the surface of workpieces of different heights. Whether it is a low part or a high area, it can ensure the stability of the spraying distance and angle, and improve the consistency of the spraying quality.

[0035] It is worth noting that, to ensure a stable supply of paint during the spraying process, a paint delivery pump 418 is fixedly installed on the upper surface of the extension arm 3, and a paint delivery pipe 419 is fixedly connected to the output end of the paint delivery pump 418. The end of the paint delivery pipe 419 away from the paint delivery pump 418 extends into the interior of the movable sleeve 401, and the paint delivery pipe 419 and the movable sleeve 401 are coaxial with each other. This design ensures that the paint delivery pipe 419 will not become entangled or worn due to relative movement when the movable sleeve 401 rotates.

[0036] The bottom end of the paint delivery pipe 419 extends to the bottom of the rotating movable arm 402 and is rotatably connected to the lower surface of the rotating movable arm 402 via a bearing, further preventing interference to the paint delivery pipe 419 when the rotating movable arm 402 rotates; a rubber hose 420 is fixedly connected to the output end of the paint delivery pipe 419, and the end of the rubber hose 420 away from the paint delivery pipe 419 is fixedly connected to the input end of the paint nozzle 411.

[0037] It is worth noting that the rubber hose 420 has good flexibility and can freely extend, retract, or bend as the paint nozzle 411 moves horizontally and vertically, completely eliminating the restriction of the hose on the movement of the nozzle.

[0038] Working Principle: In use, the robot is first moved to a suitable position near the workpiece to be sprayed using the universal wheels 5 at the front end of the arc-shaped base 1 and the moving wheels 6 at the bottom of the robot body 2. An external paint supply pipe is connected to the input end of the paint delivery pump 418 to supply paint to the equipment. The drive motor 414 is started, which drives the drive bevel gear 416 to rotate via the drive shaft 415. The drive bevel gear 416 meshes with the driven bevel gear ring 417, thereby driving the movable sleeve 401 and the rotating movable arm 402 to rotate as a whole, aligning the paint nozzle 411 with the direction to be sprayed on the workpiece, achieving initial 360° adjustment. Based on the horizontal dimensions of the workpiece, the horizontal motor 404 is started, driving the horizontal threaded rod 405 to rotate, causing the moving frame 406 to move the guide frame 407 and the paint nozzle 411 horizontally, adjusting to a suitable spray radius to ensure the nozzle can cover the horizontal range of the workpiece. Based on the workpiece height, the lifting motor 412 is started, driving the lifting screw 408 to rotate. This causes the lifting block 409 to move the paint nozzle 411 vertically up and down, adjusting it to the optimal spraying height to ensure the paint adheres evenly to the workpiece surface. Finally, the paint delivery pump 418 is started, and the paint is sequentially delivered to the paint nozzle 411 through the paint delivery pipe 419 and the rubber hose 420. The nozzle atomizes the paint and sprays it onto the workpiece surface, completing the spraying operation.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
