[0047] The working principle and beneficial effects of the above technical solution are:

[0048] The automotive topcoat station is a very important link in the entire automotive manufacturing process. It not only protects the car surface, but also enhances the appearance and appeal of the vehicle. Therefore, each automotive topcoat station on a modern automotive production line needs to be carefully designed and equipped to ensure an efficient and high-quality painting process.

[0049] The automotive topcoat station usually includes different functional areas such as the paint preparation area, paint operation area, drying area and inspection area. In the paint preparation area, skilled workers need to perform surface preparation, including removing impurities such as grease, dust, dirt, and performing operations such as sanding and filling pits. These steps are crucial for the subsequent painting process because they ensure a smooth and flat surface and are conducive to the adhesion and durability of the paint.

[0050] In spraying area 1, skilled workers need to use professional spraying equipment and tools to carry out painting according to predetermined procedures and parameters, which includes the application, drying and repair of primer and topcoat. During this process, skilled workers need to pay close attention to parameters such as paint concentration, consistency, color and coating thickness to ensure that the final painting effect meets the design requirements and reaches high quality standards.

[0051] In drying area 2, skilled workers need to use professional drying equipment to dry and cure the new coating. This process requires precise time and temperature control to ensure that the coating can dry evenly and quickly and reach the desired hardness. In addition, during the drying process, it is also necessary to pay attention to maintaining good ventilation and environmental hygiene to prevent dust and dirt from adhering to the wet paint surface and affecting the coating quality.

[0052] In the inspection area, technicians need to conduct a comprehensive inspection and evaluation of the new coating. This includes evaluation of surface flatness, glossiness, color saturation, etc. If any flaws or defects are found, technicians need to repair and reapply in time to ensure that the final coating effect meets the requirements.

[0053] The operating table 9 is an indispensable device in the automobile repair industry. It is specially designed for painting the surface of the automobile. The operating table 9 usually consists of a closed cabinet and an operating area equipped with various painting equipment. Its main function is to provide a stable surface for the automobile to spray the paint surface and to discharge the exhaust gas during the spraying process.

[0054] There are many different types of operating tables 9, and a suitable one can be selected according to different needs and space sizes. One common operating table 9 is a side-push type, which is suitable for paint application on vehicles with higher bodies because it can effectively provide a larger space and a better viewing angle.

[0055] The operating area of ​​the operating table 9 generally includes equipment such as lighting, paint spray guns, filters and motors. The lighting can provide enough light to ensure uniform coating, the paint spray gun is an important tool for spraying paint, the filter can effectively filter impurities and dust in the air, and the motor is used to drive the exhaust equipment to discharge the exhaust gas from the workbench.

[0056] When using the operating table 9, you need to pay attention to some safety matters. First, be sure to wear protective glasses and masks during operation to protect your safety. Secondly, before the paint is applied, the workbench should be thoroughly cleaned and prepared to ensure that the surface is flat and dry to avoid the mixing of dust and impurities. Finally, the equipment should be cleaned and maintained after use to ensure normal operation of the equipment when it is used next time.

[0057] The operating table 9 is a very important device in the modern automobile repair industry. It can provide a stable surface for the automobile to be painted, and can discharge exhaust gas to ensure the health and safety of the operator.

[0058] The work station inclined ladder 10 is a device used for painting cars. It is usually installed in a paint room or a painting operation area. The work station inclined ladder 10 is mainly made of metal material and is trapezoidal in shape. One side of the work station inclined ladder 10 is parallel to the ground, and the other side is inclined upward, and is equipped with a fixed handrail on the top.

[0059] The main function of the workstation inclined ladder 10 is to provide a stable platform for workers so that they can perform painting operations more conveniently and safely. The design of the inclined ladder allows it to be placed in a corner next to the vehicle and extended along the inclination angle of the vehicle body, allowing workers to easily reach all parts that need to be painted.

[0060] The workstation inclined ladder 10 can not only improve work efficiency, but also ensure construction quality. By using the inclined ladder, workers can more accurately control the distance and direction of the spray gun, so that the coating is more uniform, the coating film is denser, and the color is more vivid. In addition, the stability of the inclined ladder can also help workers better control their balance and avoid accidents.

[0061] The design of the air supply duct is a very important part of the automobile spray paint room. Its main function is to deliver fresh air into the spray paint room and maintain pressure and temperature. The correct design of the air supply duct can improve the efficiency and quality of painting, and can also effectively protect the health and safety of the staff.

[0062] Before designing the air supply duct, you first need to understand the structure and size of the spray booth. According to the size and shape of the spray booth, the designer can choose different air supply methods and duct layout plans to achieve the best air supply effect.

[0063] Normally, the air supply duct 11 of the automobile topcoat station adopts a closed circulation system for air supply, that is, fresh air is sucked into the room through a fan, and then filtered through a filter before the old air is discharged. This air supply method can ensure the fresh air in the paint room and avoid direct mixing of indoor air and outdoor air, thereby ensuring a good environment in the paint room.

[0067] Preferably, the first push head 37 is slidably connected to the limit member 24, and the end of the first push head 37 close to the push rod 25 is fixedly connected to the push rod 25, the return spring 26 is sleeved on the outer wall of the push rod 25, the end of the locking push member 23 close to the ratchet 21 is fixedly provided with an engaging member 22, the locking push member 23 is provided with a through groove 28, and the through groove 28 is provided with a clamping hole 27 larger than the aperture of the through groove 28, the limit member 24 forms a guide groove 43 inwardly, the second push head 42 is movably provided in the guide groove 43, and one end of the fifth connecting rod 40 is movably extended into the guide groove 43 and fixedly connected to the second push head 42, and the other end of the fifth connecting rod 40 extends out of the through groove 28 and is fixedly provided with a circular clamping head 29.

[0068] Preferably, the second return spring 41 is sleeved on the outer wall of the fifth connecting rod 40 located in the guide groove 43 , and the diameter of the circular clamping head 29 is larger than the diameter of the through groove 28 .

[0069] Preferably, the adjustment seat 32 is fixedly connected to the fourth connecting rod 31, and the side of the adjustment seat 32 close to the vehicle body extends to form an arc groove, the arc adjustment member 36 is movably arranged in the arc groove of the adjustment seat 32, and the side of the arc adjustment member 36 located in the arc groove is fixedly provided with an arc rack 39, the ultraviolet paint lamp 15 is installed on the arc adjustment member 36, the outer wall of the adjustment seat 32 and the corresponding positions of the arc adjustment member 36 are provided with the same pin holes 35, one end of the rotating shaft 34 is fixedly provided with an adjustment handle 33, and the other end of the rotating shaft 34 is movably extended into the adjustment seat 32 and fixedly sleeved with a driving gear 38, and the driving gear 38 is meshed with the arc rack 39.

[0070] The working principle and beneficial effects of the above technical scheme are as follows: the ultraviolet paint lamp 15 utilizes ultraviolet light source to quickly dry and cure the new coating of the car, and has the advantages of high efficiency, energy saving, and environmental protection. In the prior art, the ultraviolet paint lamp tube is usually installed on one or more fixed brackets and is usually unable to be adjusted. However, the appearance of the vehicle is not static. Due to the different shapes of different frames, the irradiation angles of several groups of ultraviolet paint lamps 15 need to be adjusted differently for different frames in order to quickly dry and cure the new coating. Therefore, when different frames enter the paint area, the ultraviolet paint lamp 15 will generate high-intensity ultraviolet light radiation to quickly dry and cure the new coating, thereby having good adaptability and versatility.

[0071] When making adjustments, it is only necessary to push the guide slider 19 to slide along the guide groove 17, thereby driving the adjustment seat 32 to change its angle through the four-link structure composed of the first link 18, the second link 20, the third link 30 and the fourth link 31, so that the ultraviolet paint lamp 15 is adjusted to a suitable position. At this time, the third link 30 will synchronously drive the ratchet 21 to rotate synchronously, and by pressing the first push head 37, the locking push piece 23 is driven to move in the direction close to the ratchet 21 until the ratchet 21 is engaged with the locking push piece 23. At this time, Fig. 9 As shown in the figure, since the diameter of the circular clamp head 29 is larger than the diameter of the through slot 28 and smaller than the diameter of the clamp hole 27, when the fifth connecting rod 40 enters the clamp hole 27 along the through slot 28, the circular clamp head 29 is no longer restricted by the through slot 28, and under the pulling of the reset spring 21, the fifth connecting rod 40 moves downward to drive the circular clamp head 29 into the clamp hole 27, thereby locking the locking push piece 23 to prevent it from moving, and locking the ratchet 21, thereby making the four-bar linkage unable to move, avoiding the ultraviolet paint lamp 15 from firing after adjustment. In order to prevent the occurrence of deviation, after adjusting a large angle in the above manner, when it is necessary to fine-tune the angle of the ultraviolet paint lamp 15 so that it can better irradiate the narrow position of the frame, it is only necessary to rotate the adjustment handle 33 to drive the driving gear 38 to rotate through the rotating shaft 34. At this time, the arc adjustment member 36 slides along the arc groove of the adjustment seat 32 driven by the arc rack 39 to achieve the purpose of fine-tuning. The arc adjustment member 36 is fixed by inserting a pin into the pin hole 35, which further avoids the occurrence of deviation of the ultraviolet paint lamp 15.

[0072] When the ultraviolet paint lamp 15 needs to be reset or changed to a large angle again, it is only necessary to press the second push head 42 so that the fifth connecting rod 40 drives the circular clamping head 29 to disengage from the clamping hole 27. At this time, under the drive of the reset spring 26, the first push head 37 will drive the locking push piece 23 to reset, thereby separating the ratchet 21 from the meshing piece 22. At this time, the ultraviolet paint lamp 15 can be adjusted to a large angle by changing the position of the guide slider 19.

[0073] It should be noted that the adjustment seat 32 and the fourth connecting rod 31 are connected by bolts, so according to the different installation directions of the adjustment seat 32, the angle of the ultraviolet paint lamp 15 in different directions can be fine-tuned, which is suitable for different working conditions. The design of the four-link ensures the precise positioning and adjustment of each part, improves the working accuracy of the equipment, and the adjustment handle 33 and the driving gear 38 cooperate with the arc rack 39 to easily adjust the position of the ultraviolet paint lamp 15. The operation is simple and the complexity of manual operation is reduced. The design of the reset spring 26 and the reset spring 41 ensures the automatic reset function of the system, which improves the safety and service life of the equipment.

[0074] By adjusting the settings of the components, the angle and position of the ultraviolet paint lamp 15 can be flexibly adjusted to adapt to vehicle bodies of different sizes and shapes, thereby improving the applicability of the equipment.
