[0002] The appearance and quality of cabinets in office furniture not only affect the aesthetics and comfort of the office environment, but also reflect the company's image and culture. Therefore, the manufacturing and processing of office furniture requires a high degree of precision and standardization. One important step is the spray coating process to improve the durability, corrosion resistance, and aesthetics of the office furniture.

[0003] According to the patent titled "A Spray Coating Device for Office Furniture" (patent publication number: CN221268650U, patent publication date: 2024-07-05), the device includes a main vertical support, a support base between the upper ends of the main vertical support, a horizontal drive group between the support bases, a vertical adjustment group on one side of the horizontal drive group, a transition plate at the end of the vertical adjustment group, an upper connecting plate connected to the transition plate, an outer support plate at the lower end of the upper connecting plate, a connecting guide between the outer support plates, and a connecting horizontal plate at the end of the connecting guide. This device enables automated spray coating of office furniture, improving production efficiency and quality, reducing labor costs and errors. By adjusting the position and height of the sprayed part and the workpiece placement seat according to different sizes and shapes of workpieces, it achieves flexibility and adaptability in spray coating. By controlling the moving speed of the sprayed part, it adjusts the amount and distribution of paint sprayed, achieving uniformity and precision in spray coating.

[0004] Based on the aforementioned existing technology, the current office furniture spraying and coating devices still have the following problems: traditional spraying and coating devices are usually fixed spray guns or simple linear moving robotic arms, which are difficult to fully cover all the complex surfaces of the furniture. Operators need to frequently move the furniture or their own position, which can easily lead to missed areas or uneven coating thickness. Therefore, this utility model provides an office furniture spraying and coating device. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A spray coating device for office furniture includes a workbench 1, and a surrounding mechanism 2 is provided inside the workbench 1 for achieving all-around spray coating of the office furniture. The surrounding mechanism 2 includes:

[0026] The rotating unit 21 is located inside the workbench 1 and includes a mounting bracket 211 fixedly installed at the bottom of the workbench 1. A disc base 212 is fixedly installed in the middle of the workbench 1 via the mounting bracket 211. A placement rack 4 is fixedly installed on the top of the disc base 212. A circular track 213 is fixedly installed at the bottom of the workbench 1 and the bottom of the disc base 212. A circular cross block 214 is slidably installed inside the circular track 213. A fixed plate 215 is fixedly installed on the top of the circular cross block 214. A spraying robot arm 3 is provided on the top of the fixed plate 215. The fixed plate 215 slides inside the circular track 213 to drive the spraying robot arm 3 to move circumferentially, thereby achieving all-round spraying of office furniture.

[0027] The drive unit 22 is located below the disk base 212 and is used to drive the rotating unit 21.

[0028] The spraying robotic arm 3 revolves 360° along the circular track 213, covering all complex surfaces of the furniture, such as edges and curves, completely eliminating the need for manual adjustment and solving the coverage blind spot problem of traditional fixed spray guns or linear robotic arms.

[0029] In this embodiment, the drive unit 22 includes a motor frame 221 fixedly installed at the bottom of the disc base 212. A drive motor 222 is fixedly installed at the bottom of the motor frame 221, and a main synchronous pulley 223 is fixedly installed through the motor frame 221 at the output end of the drive motor 222.

[0030] The drive motor 222 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed by a human-operated control panel.

[0031] In this embodiment, a rotating shaft 224 is rotatably mounted on one corner of the bottom of the workbench 1, and a secondary synchronous pulley 226 is fixedly mounted on the bottom end of the rotating shaft 224. A synchronous belt 227 is installed between the secondary synchronous pulley 226 and the main synchronous pulley 223, and a tensioning component 5 is provided at the bottom of the mounting frame 211 for tensioning the synchronous belt 227.

[0032] The timing belt 227 replaces the gearbox to transmit power, with a transmission efficiency of 95% compared to the chain drive's 82%. Furthermore, the tensioning component 5 can compensate for timing belt slack in real time, preventing spraying interruptions caused by slippage.

[0033] In this embodiment, a gear 225 is fixedly mounted on the surface of the rotating shaft 224, and a toothed ring 216 is fixedly mounted on the bottom of the circular cross block 214, with the gear 225 meshing with the toothed ring 216.

[0034] The rigid transmission of gear 225 meshing with gear ring 216 converts the rotation of shaft 224 into the revolution of the robotic arm.

[0035] In this embodiment, the tensioning assembly 5 includes a fixed frame 51 fixedly installed at the bottom of the disc base 212. The fixed frame 51 has a sliding groove 52 inside, and a sliding plate 53 is slidably installed inside the fixed frame 51. A fixed shaft 54 ​​is fixedly installed inside the sliding plate 53, and the fixed shaft 54 ​​slides inside the sliding groove 52. A tensioning wheel 55 is rotatably installed at one end of the fixed shaft 54, and the tensioning wheel 55 contacts the timing belt 227. A screw knob 56 is threaded through one side of the fixed frame 51, and one end of the screw knob 56 is rotatably connected to the sliding plate 53. The sliding plate 53 is driven by rotating the screw knob 56.

[0036] The slide plate 53 moves linearly within the slide groove 52, forcing the tension wheel 55 to vertically squeeze the timing belt 227. The tension adjustment is visible, preventing damage to the belt due to excessive tightness or slippage due to excessive looseness.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, the office furniture to be painted is placed on the rack 4. The drive motor 222 drives the main synchronous pulley 223 to rotate. The main synchronous pulley 223 drives the secondary synchronous pulley 226 to rotate via the synchronous belt 227. The secondary synchronous pulley 226 drives the rotating shaft 224 to rotate. The rotating shaft 224 drives the gear 225 to rotate. The gear 225 drives the gear ring 216 to rotate. The gear ring 216 drives the fixed plate 215 to rotate via the circular cross block 214. The fixed plate 215 drives the painting robot arm 3 to rotate. The painting robot arm 3 paints the office furniture. Before the synchronous belt 227 starts running, the operator turns the screw knob 56 to push the slide plate 53 to move. The slide plate 53 drives the tensioning wheel 55 to move via the fixed shaft 54. The tensioning wheel 55 presses the synchronous belt 227 to tension it.
