Description

Technical Field

[0001] This invention patent discloses a novel contour-following point repair chamber, which relates to the fields of automobile manufacturing technology and low-altitude manned aircraft manufacturing technology. It is suitable for use with skid conveying systems and for repairing the top of workpieces. Background Technology

[0002] In recent years, with the increasing maturity of my country's automotive industry and the rise of the low-altitude manned aircraft industry, various forms of painting production lines have rapidly increased. Even with the most advanced automated spraying technology and nominally cleanrooms, it is impossible to guarantee that all products will be qualified. Therefore, several offline spot repair stations need to be set up at the end of the production line to handle products with minor defects. The repaired products can then proceed to the next process as qualified products. The number of spot repair stations varies slightly depending on the production line capacity, but is generally around four. Since the spot repair station needs to spray paint on the surface of the workpiece, it will generate exhaust gas containing VOCs. Therefore, the spot repair station needs to be equipped with a ventilation system to supply constant temperature and humidity fresh air and exhaust VOCs-containing exhaust gas, while also ensuring adequate illuminance. How to rationally utilize space, reduce air supply and exhaust volume, reduce energy consumption, and ensure the illuminance requirements of all surfaces of the workpiece has become a research direction in the optimization design of spot repair equipment.

[0003] Most existing spot repair equipment uses a non-conformal right-angle connection, with the top panel of the chamber pressing against the side panels. The chamber's lighting is all located outside the side windows, resulting in a lack of top lighting and hindering manual operation. While enhanced top lighting is often achieved using built-in light boxes, the interior of the spot repair chamber is an explosion-proof area, requiring relatively expensive explosion-proof lighting fixtures, which negatively impacts cost control and reduces the equipment's competitiveness. Furthermore, the right-angle connection creates a large top air supply area, while the paint volume in the spot repair chamber is relatively small, resulting in much fresh air being delivered to ineffective areas. The use of constant-temperature and humidity fresh air from outside leads to significant energy waste and hinders operating cost control. To address these issues, our company has successfully developed a new type of conformal spot repair chamber. This new chamber increases top lighting for the workpiece while using ordinary non-explosion-proof light boxes, reducing equipment costs. Simultaneously, without reducing the downward airflow velocity on and around the workpiece, it reduces the area of ​​ineffective air supply areas, significantly saving energy consumption and lowering operating costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a contour point repair chamber that can both increase the lighting on the top of the workpiece, reduce construction costs, and reduce the supply and exhaust air volume.

[0005] To achieve the above objectives, a novel contour-following repair chamber is provided, comprising a 45° folded C-shaped steel, with two folded wall panels fixedly connected internally to the 45° folded C-shaped steel, and two air supply static pressure layers fixedly connected to the top of the 45° folded C-shaped steel.

[0006] According to the novel contour repair chamber, the 45° folded C-shaped steel has two glass panels and their frames fixedly connected internally, and a workpiece entry and exit roller shutter is fixedly connected externally to the 45° folded C-shaped steel.

[0007] According to the novel contour-following repair chamber, two lighting lamps are fixedly connected inside the folded wall panel.

[0008] Beneficial effects:

[0009] 1. A large glass window is installed on the upper sloping side of the chamber, allowing the light from the external lighting to shine through the glass onto the top of the workpiece inside. At the same time, the various parts of the chamber are sealed to ensure that VOCs-containing gases do not leak out. The lighting does not need to be explosion-proof, reducing installation costs.

[0010] 2. The sloping ceiling design ensures that the personnel operating area receives a small amount of fresh air, maintaining a safe working environment. Simultaneously, a large amount of fresh air passes through the workpiece area, effectively carrying away paint mist and preventing contamination of the workpiece.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-2 This utility model embodiment provides a novel contour-following repair chamber, which includes a 45° folded C-shaped steel 1, with two folded wall panels 2 fixedly connected inside the 45° folded C-shaped steel 1, and two air supply static pressure layers 5 fixedly connected to the top of the 45° folded C-shaped steel 1.

[0019] Specifically, the system includes 45° folded C-shaped steel, folded wall panels, lighting fixtures, glass, and their frames. The main function of the 45° folded C-shaped steel is to form a high-strength framework, supporting the wall panels, lighting fixtures, glass windows, and the ceiling pressure layer. The main function of the folded wall panels is to fill the spaces between the wall panel framework, forming a closed structure to prevent paint mist from overflowing, while also reflecting light to enhance indoor illumination. The main function of the lighting fixtures is to provide illumination for the room, ensuring the required indoor illuminance. The main function of the glass is to allow outdoor light to enter the room while preventing indoor VOCs from escaping outdoors. The glass is made of 2.0mm–3.0mm thick steel plate, while the panels are made of 0.4mm–1.0mm thick steel plate, possessing sufficient strength. At the corners, the glass is broken into two independent sections for separate transport and on-site bolt connection. This structure facilitates transportation and also functions as a cable tray for the lighting fixtures, preventing cable exposure and ensuring the overall aesthetics of the equipment. The C-shaped steel is bolted together for easy installation. The wall panels are made of 1.0mm to 1.5mm steel plates and filled between the folded C-shaped steel. The steel plates are punched before folding and connected by bolts. After connection, sealant is applied to ensure the airtightness of the equipment.

[0020] The internal fixed connection of the 45° folded C-shaped steel 1 consists of two glass panels and their frame 4, and the external fixed connection of the 45° folded C-shaped steel 1 consists of a workpiece entry and exit roller shutter door 6.

[0021] Specifically: The frame is embedded between the folded wall panels, and the frame is bolted to the wall panels / C-shaped steel. After connection, sealant is applied to ensure the equipment's airtightness. Tempered or laminated glass is used to ensure safety.

[0022] Two lighting lamps 3 are fixedly connected inside the folded wall panel 2.

[0023] Specifically: an external lighting box with a reflector, which does not require explosion-proof treatment, and the number and power of different lamps are configured according to different indoor illuminance levels.

[0024] Working principle: When workpieces are being repaired inside the roller shutter door 6, the side and upper side lighting 3 is turned on. Light shines through the glass and its frame 4 onto the sides and top of the roller shutter door 6, meeting the illumination requirements for workpiece repair. At the same time, the air supply static pressure layer 5 is located directly above the roller shutter door 6. Most of the air is discharged after passing through the area near the roller shutter door 6, thus carrying away paint mist; a small amount of air is supplied to the manual operation area, thereby improving the environment of the manual operation area.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
