Description

Technical Field

[0001] This utility model relates to the technical field of spraying auxiliary devices, specifically to a vacuum spraying auxiliary device for coating processing. Background Technology

[0002] To improve the processing efficiency of workpiece coating, a fixing device is used to assist in fixing the workpiece so that the vacuum spraying equipment can spray the workpiece, which is a method of workpiece coating processing.

[0003] Chinese patent document CN221108674U discloses a vacuum spraying auxiliary device for coating processing, including a workpiece holder. The workpiece holder is equipped with a clamping device, a flipping device, and a rotating device. The clamping device includes a cylinder, a mounting frame, a connecting frame, a connecting rod, and grippers. The grippers and connecting rods are provided in two sets. The middle of each of the two grippers is rotatably connected to the mounting frame. One end of each of the two connecting rods is rotatably connected to one end of each of the two grippers, and the other end is rotatably connected to the connecting frame. The other end of the connecting frame is connected to the telescopic end of the cylinder. The connecting frame has guide grooves on both sides that slide with the mounting frame. The cylinder is fixedly mounted on the mounting frame and installed on the flipping device. The rotating device includes a first motor, a fixed base, and a rotating base. The first motor is embedded in the fixed base, and the rotating base is rotatably mounted on the upper surface of the fixed base. The centerline of the rotating base is connected to the output shaft of the first motor.

[0004] However, in the above solution, the workpiece holder is clamped by a cylinder-driven gripper and rotated by a motor. This only allows the workpiece to rotate in one direction. Since the workpiece has various shapes (such as rectangles and circles), when spraying workpieces with multiple coating surfaces, the workpiece needs to be unloaded and re-fixed, which makes the workpiece spraying inconvenient and affects the spraying efficiency.

[0034] Example 1

[0035] like Figure 1-4 As shown, the present invention proposes a vacuum spraying auxiliary device for coating processing, comprising a base 1, a rotating assembly, a clamping assembly, and an adjusting assembly;

[0036] A rotating assembly is installed at the top of the base 1, and a workpiece holder 5 is provided above the rotating assembly for supporting the workpiece in use. There is at least one workpiece holder 5, which is used to install multiple workpieces separately in use so that the workpieces can be continuously sprayed. In use, the workpiece holder 5 can be selected as a workpiece holder 5 with a perforated plate shape in the middle, and the connection between the workpiece holder 5 and the workpiece is prior art, which is not shown in the figure.

[0037] The clamping assembly has two clamping components. The two clamping components are symmetrically installed on the top of the rotating assembly and connected to the workpiece frame 5 according to the center of the workpiece frame 5. One end of the clamping assembly is provided with a second motor 9 for rotating the clamping assembly on the rotating assembly in the use state. When in use, the clamping assembly is driven to rotate by the second motor 9, so that the clamping assembly drives the workpiece frame 5 to rotate according to the axial direction of the second motor 9, so that the workpiece can be adjusted at multiple angles.

[0038] The adjustment component is located at the top of the rotating component and on the side of the clamping component, with one end extending toward the workpiece holder 5 and engaging with it. It is used to rotate the workpiece holder 5 laterally on the clamping component during use, so that the workpiece rotates along the height direction as the axis, thereby increasing the spraying range of the workpiece.

[0039] In this embodiment, the workpiece holder 5 is fixed on the rotating assembly by the clamping assembly, and the rotating assembly moves the workpiece fixed on the workpiece holder 5 to the spraying area through the clamping assembly. The second motor 9 is started to drive the clamping assembly to rotate on the rotating seat to achieve multi-angle spraying of the workpiece. The adjusting assembly extends to the workpiece holder 5 and engages with the workpiece holder 5. At the same time, the clamping assembly is slightly loosened, so that the adjusting assembly rotates the workpiece holder 5 in the clamping assembly. This achieves precise position adjustment of the workpiece during the spraying process and increases the spraying area of ​​the workpiece, thereby ensuring uniform coating coverage and improving spraying efficiency and quality.

[0040] Example 2

[0041] like Figure 4 As shown, the present invention proposes a vacuum spraying auxiliary device for coating processing. Compared with the first embodiment, the difference in this embodiment is that the rotating component includes a mounting plate 2, a third motor 10, a slider 14, a second gear 16, and a slide rail 17.

[0042] The slide rail 17 is mounted on the top of the base 1 and is circular in shape;

[0043] There are multiple sliders 14, and all sliders 14 are slidably mounted on the slide rail 17. Among them, the sliders 14 are roller sliders, which move on the slide rail 17 by means of rollers during use, thereby adapting to the shape of the slide rail 17.

[0044] The third motor 10 is mounted on a slider 14 with its output shaft facing the base 1;

[0045] The second gear 16 is mounted on the output shaft of the third motor 10 and meshes with the slide rail 17.

[0046] Mounting plate 2 is mounted on the top of slider 14, and its top has a structure for mounting clamping components and adjusting components. The prior art drawings are for illustrative purposes only.

[0047] In an optional embodiment, a toothed ring 15 is provided at the bottom end of the slide rail 17 and below the slider 14, and the second gear 16 meshes with the toothed ring 15.

[0048] In this embodiment, a toothed ring 15 is provided at the bottom end of the slide rail 17, and the second gear 16 is meshed with the toothed ring 15. The mounting plate 2 is mounted on multiple sliders 14. The third motor 10 is started to drive the second gear 16 to rotate, and the second gear 16 rotates on the toothed ring 15. An interaction force is generated between the toothed ring 15 and the second gear 16, which in turn drives the sliders 14 to slide on the slide rail 17 through the third motor 10. The mounting plate 2 moves multiple sliders 14 synchronously, and the mounting plate 2 is angled to allow continuous loading and unloading of workpieces, thereby realizing an automated workpiece spraying process and improving production efficiency.

[0049] Example 3

[0050] like Figure 3 As shown, the present invention proposes a vacuum spraying auxiliary device for coating processing. The difference between this embodiment and the first embodiment is that the clamping assembly includes a connecting shell 3 and a gripper 4.

[0051] The connecting shell 3 is mounted on the top of the mounting plate 2 via a bearing seat;

[0052] The gripper 4 is installed inside the connecting shell 3 and its end extends to the outside of the connecting shell 3 to connect with the workpiece holder 5.

[0053] In an optional embodiment, the upper and lower end faces of the workpiece holder 5 are provided with grooves 11 near the edges, and the end of the gripper 4 is provided with a protrusion 13. When the gripper 4 and the workpiece holder 5 are installed together, the protrusion 13 is accommodated in the groove 11.

[0054] In this embodiment, the gripper 4 is installed inside the connecting shell 3, and the connecting shell 3 is connected to the mounting plate 2 through the bearing seat. This ensures the stable installation of the gripper 4 and allows the gripper 4 to rotate through the connecting shell 3. The gripper 4 drives the workpiece frame 5 to rotate according to the bearing seat. At the same time, by setting a protrusion 13 at the end of the gripper 4 and precisely cooperating with the slide groove 11 of the workpiece frame 5, the gripper 4 can accurately clamp at the edge of the workpiece frame 5. When the adjusting component is engaged with the workpiece frame 5, the top of the protrusion 13 of the gripper 4 is moved to the outside of the slide groove 11, so that the gripper 4 can loosen its clamping of the workpiece frame 5 and prevent the workpiece frame 5 from falling off. The workpiece frame 5 is driven by the adjusting component to rotate on the gripper 4.

[0055] Example 4

[0056] like Figure 2As shown, the present invention proposes a vacuum spraying auxiliary device for coating processing. Compared with the first embodiment, the difference in this embodiment is that the adjustment component includes a first motor 6, a first gear 7, and a cylinder 8.

[0057] Cylinder 8 is mounted on the top of mounting plate 2 with its piston rod facing workpiece holder 5;

[0058] The first motor 6 is mounted at the end of the cylinder 8 with its output shaft facing directly upwards;

[0059] The first gear 7 is mounted on the output shaft of the first motor 6 and meshes with the workpiece holder 5.

[0060] In an optional embodiment, a toothed groove 12 is provided at the bottom edge of the workpiece holder 5, and the workpiece holder 5 is connected to the first gear 7 through the toothed groove 12.

[0061] In this embodiment, the cylinder 8 drives the first motor 6 to move toward the workpiece holder 5, so that the first motor 6 drives the first gear 7 to mesh with the workpiece holder 5 through the tooth groove 12. The first motor 6 starts and drives the first gear 7 to rotate, so that the first gear 7 drives the workpiece holder 5 to rotate in the gripper 4, so that the workpiece on the workpiece holder 5 can be sprayed from multiple angles, thereby realizing all-round spraying of the workpiece and improving the uniformity and quality of spraying.

[0062] In this invention, the workpiece holder 5 is clamped and fixed by the gripper 4, and the second gear 16 is driven to rotate by the third motor 10. The second gear 16, in conjunction with the gear ring 15, causes the third motor 10 to drive the slider 14 to slide on the slide rail 17. The mounting plate 2 moves multiple sliders 14 synchronously, allowing the mounting plate 2 to adjust its angle and move the workpiece to the spraying area. Simultaneously, the gripper 4 releases the workpiece holder 5, allowing the protrusion 13 to engage with the slide groove 11 to limit the workpiece holder 5. At the same time, the cylinder 8 drives the first motor 6 to move toward the workpiece holder 5, causing the first motor 6 to drive the first gear 7 to mesh with the workpiece holder 5 through the tooth groove 12. The first motor 6 drives the first gear 7 to rotate, causing the workpiece holder 5 to rotate on the gripper 4, thus rotating the workpiece holder 5 laterally. At the same time, the gripper 4 clamps the workpiece holder 5, and the cylinder 8 resets the first gear 7. The first gear 7 is then connected to the mounting plate 2 bearing via the connecting shell 3, causing the second motor 9 to start and drive the connecting shell 3 to rotate. The connecting shell 3 then drives the workpiece holder 5 to rotate via the gripper 4, realizing multi-dimensional rotational spraying of the workpiece. This ensures a wider spraying coverage, thereby improving the overall spraying effect and quality of the workpiece. The rotation of the mounting plate 2 enables continuous loading and unloading of the workpiece, thus realizing an automated spraying process and improving production efficiency.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
