Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, and in particular to an automated production line for hubcap painting and baking. Background Technology

[0002] In modern industrial production, spray painting, as a core step in surface treatment, is widely used in automotive parts, home appliances, aerospace, and other fields. However, if the volatile organic compounds (VOCs) and paint mist particles generated during the spray painting process are emitted directly without effective treatment, they will not only seriously pollute the atmospheric environment but also pose a threat to the health of operators. Traditional spray painting production lines typically adopt a separate "spray first, treat later" model, where spray painting and exhaust gas purification operate as independent processes. This results in large equipment footprints, high energy consumption, and exhaust gas treatment efficiency limited by the continuity of the spray painting process.

[0003] In the existing technology, most companies address the problem of paint spraying pollution through independently installed waste gas treatment devices. For example, Chinese patent application number 201720064525.0 discloses a paint spraying operation waste gas separation, adsorption, and purification device, which achieves local collection of paint mist and activated carbon adsorption treatment through a combination of a protective cover, a fan, and a filter. However, this solution only focuses on the final treatment of waste gas and is not deeply integrated with the paint spraying process, resulting in easy diffusion of paint mist during transmission, frequent replacement of activated carbon, and high maintenance costs.

[0004] Similarly, Chinese patent application number 202421355715.4 proposes a VOCs organic waste gas collection and treatment device for aluminum single-panel painting, which adopts a dual-chamber circulating adsorption structure to improve purification efficiency. However, its design still focuses on the waste gas treatment process itself and does not solve the problem of synergistic optimization between the painting and purification processes. The limitations of this kind of separate technical approach are that the paint mist generated by painting needs to be transported to the treatment equipment through long-distance pipelines. During the process, it is easy to condense and deposit, clogging the pipeline. Moreover, the independently operating painting equipment and waste gas treatment device are difficult to dynamically adjust according to the operating conditions, resulting in energy waste and fluctuations in treatment efficiency.

[0005] To address the aforementioned issues, there is an urgent need to propose a novel automated production line for hubcap painting and baking. By integrating the painting process with the purification process, it can achieve source control and immediate treatment of pollutants, thereby shortening the processing chain, reducing intermediate losses, and improving equipment space utilization. This not only significantly reduces VOC emissions but also lowers the environmental protection investment costs for enterprises through compact design. Ultimately, while ensuring production efficiency, it promotes the transformation of the painting industry towards a green manufacturing model. Utility Model Content

[0041] The baking conveying device 3 includes a feeding device 31, and a baking device 32 and a cooling device 33 sequentially mounted on the feeding device 31.

[0042] Specifically, the painting device 1 mainly consists of a working base 11, a working platform 12, a working bracket 14, and an anti-static spraying device 15, a paint spraying device 16, and a hub cover transfer device 17 mounted on the working bracket 14.

[0045] like Figure 5 and Figure 6 As shown, in this embodiment, a meshing tooth 131 is provided at the lower end of the hub cap placement component 13. A working support rod 121 rotatably connects to the hub cap placement component 13 and a working rotating device 122 drives the hub cap placement component 13 to rotate in the working platform 12. The working rotating device 122 includes a hub cap rotating motor 123 provided in the working platform 12, an active gear seat 124 connected to the hub cap rotating motor 123, and a mating gear seat 125.

[0047] The working platform 12 includes a working support rod 121 rotatably connected to the hub cap placement component 13 and a working rotation device 122 for driving the hub cap placement component 13 to rotate. The working support rod 121 supports the hub cap placement component 13, ensuring its stability during rotation. The working rotation device 122 includes a hub cap rotation motor 123, a drive gear seat 124, and a mating gear seat 125. The hub cap rotation motor 123 provides power, and the drive gear seat 124 connects to the hub cap rotation motor 123, transmitting the motor's power. Both the upper and lower ends of the drive gear seat 124 and the mating gear seat 125 are equipped with locking teeth. This design allows the drive gear seat 124 and the mating gear seat 125 to reliably mesh with other transmission components through the locking teeth. A first transmission gear chain 126 is engaged at the lower ends of the driving gear seat 124 and the mating gear seat 125, and a second transmission gear chain 127 is engaged at the upper ends of both the driving gear seat 124 and the mating gear seat 125, with engaging teeth 131. Through this transmission method, the power of the hub cover rotation motor 123 can be effectively transmitted to the hub cover mounting member 13, achieving stable rotation of the hub cover mounting member 13.

[0048] like Figure 5 As shown, in this embodiment, a platform rotation device 111 for driving the work platform 12 to rotate is provided in the work base 11. The work platform 12 includes a platform rotation motor 112 fixedly connected to the work base 11. The platform rotation motor 112 is located at the center of the rotating shaft of the work base 11 and the work platform 12 rotating relative to each other. The platform rotation motor 112 is connected to an inner platform support 113, which is fixedly connected to the work platform 12.

[0049] Specifically, a platform rotation device 111 for driving the work platform 12 is provided in the work base 11. The platform rotation device 111 includes a platform rotation motor 112 fixedly connected in the work base 11, and the platform rotation motor 112 is located at the center of the rotating shaft between the work base 11 and the work platform 12. This layout allows the platform rotation motor 112 to directly drive the work platform 12 to rotate around the rotating shaft, resulting in a compact structure and high transmission efficiency. The platform rotation motor 112 is connected to an inner platform support 113, which is fixedly connected to the work platform 12. Through this connection, the power of the platform rotation motor 112 can be reliably transmitted to the work platform 12, achieving smooth rotation of the work platform 12. The rotation of the work platform 12 allows the hub cap placed on the hub cap placement component 13 to sequentially pass through the anti-static spraying device 15, the paint spraying device 16, and the hub cap transfer device 17, completing the corresponding process flow.

[0050] like Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the circulating purification device 2 is disposed on one side of the paint spraying device 16. The circulating housing 21 has a purification opening 211 facing the paint spraying device 16. A liquid guiding plate 22 inclined towards the paint spraying device 16 is disposed in the circulating housing 21. A guide fan 212 facing the liquid guiding plate 22 is disposed at the upper end of the circulating housing 21. A circulating liquid storage tank 23 is disposed below the liquid guiding plate 22. The circulating liquid storage tank is connected to an inlet pipe 232 and a waste liquid discharge pipe 233.

[0051] Specifically, the liquid guiding inclined plate 22 is disposed in the circulation housing 21 and is inclined towards the paint spraying device 16. This inclined design allows the paint mist and harmful gases entering the circulation housing 21 from the purification opening 211 to flow downwards along the liquid guiding inclined plate 22 after contacting it, facilitating subsequent collection and treatment. A diversion pipe 221 and multiple atomizers 222 are disposed at the upper end of the liquid guiding inclined plate 22. The function of the diversion pipe 221 is to evenly distribute the liquid in the circulation storage tank 23 to each atomizer 222. The atomizers 222 atomize the liquid into tiny particles. These atomized liquid particles can fully contact the paint mist and harmful gases, removing harmful substances from the paint mist and harmful gases through adsorption, dissolution, and other processes.

[0052] A circulating liquid storage tank 23 is provided at the lower end of the circulating housing 21. The circulating liquid storage tank 23 is used to store the liquid used in the purification process. A water pump 231 is installed in the circulating liquid storage tank 23, which is connected to the diversion pipe 221 and the atomizer 222. The water pump 231 draws the liquid from the circulating liquid storage tank 23 and delivers it to the atomizer 222 through the diversion pipe 221, forming a liquid recycling system. This circulating purification method can not only effectively purify the paint mist and harmful gases generated during the paint spraying process, but also save water resources and reduce production costs.

[0053] A guide fan 212 is provided at the upper end of the circulation housing 21, which faces the guide liquid inclined plate 22. The function of the guide fan 212 is to guide paint mist and harmful gases into the circulation housing 21 and make them better contact with the atomized liquid particles, thereby improving the purification effect.

[0054] like Figures 1 to 3 As shown, in this embodiment, at least part of the feeding device 31 is disposed below the hub cover transfer device 17, the baking device 32 includes a baking box 321 covered on the feeding device 31, wherein the length of the feeding device 31 is greater than the length of the baking box 321, and the length of the baking box 321 is not less than eight meters, and the cooling device 33 includes a cooling box 331 covered on the feeding device 31.

[0055] Specifically, at least part of the feeding device 31 is located below the hub cap transfer device 17, allowing the hub cap transfer device 17 to directly place the painted hub caps onto the feeding device 31, achieving continuous conveying of the hub caps on the production line. The baking device 32 includes a baking oven 321 covered by the feeding device 31. The length of the feeding device 31 is greater than the length of the baking oven 321, and the length of the baking oven 321 is not less than eight meters. This design allows the hub caps sufficient residence time inside the baking oven 321, ensuring that the paint surface has time to level, resulting in a naturally smooth surface and allowing for thorough drying and curing. The baking oven 321 is typically equipped with heating elements and a temperature control system, enabling precise control of the baking temperature and ensuring baking quality.

[0056] Furthermore, the cooling device 33 includes a cooling box 331 covered by the feeding device 31. The cooling box 331 can adopt natural cooling or forced cooling. Natural cooling achieves the cooling of the hub cover through heat exchange between the cooling box 331 and the external environment; forced cooling can accelerate the cooling speed of the hub cover by installing equipment such as fans and cooling water pipes inside the cooling box 331.

A transmission belt 1645 is arranged on the first transmission wheels 1643 and the second transmission wheels 1644.

[0066] Specifically, a paint spraying device 16 is provided on one side of the working support 14 adjacent to the antistatic spraying device 15. The paint spraying device 16 includes a spraying slide rail 161 mounted on the working support 14, a paint spraying slide bar 162 slidably connected to the spraying slide rail 161, and a paint spraying assembly 163 attached to the paint spraying slide bar 162. The spraying slide rail 161 provides a sliding track for the paint spraying slide bar 162, enabling the paint spraying slide bar 162 to drive the paint spraying assembly 163 to move horizontally on the working support 14, thereby achieving paint spraying at different positions of the hub cover.

[0067] The painting assembly 163 includes a positioning frame 1631 attached to the painting slide bar 162 and multiple adjusting support plates 1632 fixedly connected to the positioning frame 1631.

Multiple first transmission wheels 1643 are provided on the drive rod 1641 to engage with the drive rod 1641. Second transmission wheels 1644 are engaged on the paint spraying support rod 1633. A transmission belt 1645 is arranged on the first transmission wheels 1643 and the second transmission wheels 1644. The adjusting motor 1642 drives the drive rod 1641 to rotate. The drive rod 1641 transmits power to the paint spraying support rod 1633 through the first transmission wheel 1643, the transmission belt 1645 and the second transmission wheel 1644, thereby realizing the rotation of the paint spraying support rod 1633, and thus adjusting the spraying angle of the paint nozzle 1634 to meet the requirements of different hub shapes and painting processes.

[0069] like Figure 10As shown, in this embodiment, a hub cap transfer device 17 is provided on one side of the working bracket 14 adjacent to the paint spraying device 16.
