Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts spraying devices, specifically a multi-angle spraying device for automotive parts. Background Technology

[0002] In automobile manufacturing, the painting of automotive parts is a crucial step. With the rapid development of the automotive industry, the types of automotive parts are becoming increasingly diverse and their shapes are becoming more complex, which places higher demands on the painting process.

[0003] However, existing multi-angle spraying devices for automotive parts have many problems in practical applications. Currently, most spraying operations still rely mainly on manual operation, where workers need to hold the spray gun to spray automotive parts. This traditional method is not only extremely labor-intensive, but also prone to fatigue as workers hold the spray gun in a specific posture for long periods, thus affecting the efficiency and quality of the spraying operation. Moreover, manual operation makes it difficult to achieve precise multi-angle spraying control. Due to the limited range of motion and flexibility of the human arm, it is difficult to ensure that the spray gun can accurately spray at each required angle when dealing with automotive parts with complex shapes and multiple special angle surfaces. This easily leads to problems such as uneven spraying and missed spraying, resulting in inconsistent surface quality of the parts. This not only affects the overall aesthetics of the car, but also easily reduces the performance of the parts, increasing the cost and time of subsequent rework.

[0004] Therefore, this utility model provides a multi-angle spraying device for automotive parts to solve the above problems. Utility Model Content

[0015] 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.

[0016] This utility model provides a multi-angle spraying device for automotive parts, such as... Figures 1-5 As shown, the system includes a support base 1, with a placement base 2 fixedly mounted on its top. A ring 3 is rotatably mounted on the placement base 2 via a bearing. This mounting method allows the ring 3 to rotate flexibly around the placement base 2, enabling multi-angle spraying of the subsequent fixed frame 4 and spray head 52, greatly improving the coverage and flexibility of the spraying. A fixed frame 4 is fixedly mounted on the ring 3, and a sliding block 64 is slidably mounted on the bottom of the inner wall of the fixed frame 4. The sliding block 64 has a material conveying channel inside, and one end of the sliding block 64 penetrates the side wall of the fixed frame 4. A rubber tube 51 is connected, and a drive pump 55 is connected to the end of the rubber tube 51. A storage box 5 is connected to the bottom of the drive pump 55, and the storage box 5 is fixedly installed on the side wall of the fixed frame 4. The other end of the sliding block 64 is connected to the spray head 52. By moving the sliding block 64 up and down, the spray head 52 can be closer to the surface of the accessory, so as to achieve more uniform and comprehensive spraying and avoid the occurrence of spraying dead corners. A drive component is provided on the placement seat 2 to drive the ring 3 to rotate. A telescopic component is provided on the fixed frame 4 to control the up and down movement of the sliding block 64.

[0017] The drive assembly includes a gear ring 7 fixedly mounted at the bottom of the ring 3, a fixing plate 71 fixedly mounted at the bottom of the placement seat 2, and a servo motor 72 fixedly mounted at the end of the fixing plate 71. A gear 73 is fixedly mounted on the output shaft of the servo motor 72. The gear 73 meshes with the gear ring 7. Through the meshing transmission between the gear 73 and the gear ring 7, the rotational motion of the servo motor 72 is transmitted to the ring 3, realizing the precise rotation of the ring 3. This drive method can flexibly adjust the rotational speed and direction of the ring 3 according to different spraying requirements, thereby controlling the rotation of the fixing frame 4 and the spray head 52, realizing multi-angle and all-round spraying of automotive parts, and improving the uniformity and quality of spraying.

[0018] The telescopic assembly includes a connecting plate 62 fixedly installed inside the fixed frame 4, and a cylinder 61 is fixedly installed at the top of the connecting plate 62. A piston rod 63 is fixedly connected to the output end of the cylinder 61, and a sliding block 64 is fixedly connected to the end of the piston rod 63. Driven by the cylinder 61, the piston rod 63 can perform linear reciprocating motion, thereby driving the sliding block 64 to slide up and down at the bottom of the inner wall of the fixed frame 4. This allows the spray head 52 to be precisely adjusted in the vertical direction, adapting to automotive parts of different heights and shapes, ensuring that the spray head 52 maintains a suitable distance from the surface of the parts, achieving uniform spraying, and improving the versatility and spraying quality of the device.

[0019] Among them, the top side wall of the fixed frame 4 is fixedly installed with a side plate 6 by multiple sets of bolts. The side plate 6 can prevent external impurities from entering the interior of the fixed frame 4 and protect the operation of the cylinder 61.

[0020] Among them, a baffle 31 is fixedly installed at the top of the ring 3. The baffle 31 can effectively block the splashed paint and prevent it from splashing onto other parts of the device or the surrounding environment. This not only keeps the device clean, but also reduces subsequent cleaning work.

[0021] Working principle: First, the car workpiece to be painted is placed stably on the placement seat 2. Then, the servo motor 72 in the drive assembly is started. The servo motor 72 starts to run, and its output shaft drives the fixedly installed gear 73 to rotate. The rotation of gear 73 will drive the gear ring 7 to rotate synchronously, which in turn causes the ring 3 to rotate. The rotation of the ring 3 will drive the fixed frame 4 fixedly installed on it to rotate together. Since the ring 3 can achieve 360-degree rotation, the fixed frame 4 also has the ability to rotate 360 ​​degrees, which provides the basis for the subsequent all-round painting of the workpiece. At the same time, the drive pump 55 is started and begins to work. Under the action of the pump, the liquid paint stored in the storage tank 5 is extracted. The paint enters the rubber tube 51 through the pipe connected to the bottom of the storage tank 5. The paint enters the material conveying channel opened inside the sliding block 64 through the rubber tube 51, and then enters the spray head 52 connected to the other end of the sliding block 64 from the material conveying channel. Finally, it is evenly sprayed out from the spray head 52 to perform preliminary spraying on the car workpiece placed on the placement seat 2. Since the fixed frame 4 is constantly rotating, the spray head 52 also moves in a circle around the workpiece, thereby realizing the preliminary all-round spraying of the workpiece surface.

[0022] To further improve the uniformity and coverage of the spraying, cylinder 61 in the telescopic assembly needs to be activated. Cylinder 61 begins operation, and its output end drives piston rod 63 to move up and down. The end of piston rod 63 is fixedly connected to sliding block 64. Therefore, the up-and-down movement of piston rod 63 causes sliding block 64 to slide up and down at the bottom of the inner wall of fixed frame 4. The movement of sliding block 64, in turn, causes spray head 52 to move up and down synchronously. Thus, while fixed frame 4 rotates, spray head 52 can also reciprocate vertically, allowing paint to be sprayed more evenly onto all parts of the automotive workpiece.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
