Description

Technical Field

[0001] The utility model relates to the technical field of automobile processing, in particular to a short-wave infrared heating device for wax injection into the inner cavity of a vehicle door or a door pillar. Background Art

[0002] During the production process in the automobile paint shop, the inner cavity of the car body often enters water and becomes damp, which causes the inner cavity to be in a humid environment for a long time, resulting in severe rust on the iron plate and finally damage to the lower door sill iron plate, affecting the safety and appearance of the entire vehicle.

[0003] In order to solve the problem of rust prevention in the inner cavity, the most popular method is to inject wax through the process holes in the inner cavity to increase the anti-rust performance of the inner cavity. However, due to the relatively low temperature of the car body, the wax layer condenses too thickly during the wax injection process, not only too much wax is used, but more importantly, the wax layer falls off due to vibration during use, and the anti-rust effect is not achieved. In order to achieve the required film thickness, the wax is injected while heating in a drying furnace. The drying furnace has a long preheating time, and the cooling time after extinguishing is also long. It also requires a large amount of energy such as natural gas and electricity, which greatly increases the production cost and produces a large amount of carbon dioxide gas, which affects the environment. In addition, after the wax liquid melts, it drips down and drips on the heating body at the bottom, which not only causes unsightly appearance, but also affects the heating effect of the heating body.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0040] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0041] Reference Figure 1-7 A short-wave infrared heating device for wax injection into the inner cavity of a vehicle door or door pillar according to the present embodiment is described.

[0042] In this embodiment, the device includes a fixed bracket 1, a fan 8, a housing 4, a high temperature resistant glass 5, a scraper mechanism 6 and an air equalization component 7. The device also includes a temperature sensor 3, which is fixed on the fixed bracket and is arranged close to the infrared baking lamp 2.

[0043] The fixing bracket 1 is located on both sides of the processing position of the vehicle shell, and an infrared heating lamp 2 is arranged on the fixing bracket 1, and the infrared heating lamp 2 is connected to the fixing bracket 1 through a universal hinge; the shell 4 wraps or semi-wraps the infrared heating lamp 2 to prevent the wax liquid flowing out of the door and the door pillar from dripping on the infrared heating lamp 2. The high temperature resistant glass 5 is inlaid on the top surface of the shell 4, and the wax liquid flowing out of the door and the door pillar drips on the high temperature resistant glass 5.

[0044] The housing 4 has a connection part and an opening part, and the infrared lamp 2 is fixed on the connection part; the fan 8 is connected to the housing 4, and the heat generated by the infrared lamp 2 is converted into hot air and blown out through the opening part and blown on the vehicle shell. The heat emitted by the infrared lamp 2 can be blown on the vehicle door and door pillar quickly and evenly, thereby improving the heat utilization rate.

[0045] The scraping mechanism 6 is arranged on the housing 4, and the scraping mechanism 6 includes a moving component and a scraping component. The moving component drives the scraping component to move, and scrapes the material on the surface of the high temperature resistant glass 5, and the material is the wax liquid dripped on the high temperature resistant glass 5. In the specific implementation process, a timing device can be set to make the moving component work at a fixed time to drive the scraping component to move, so as to achieve the purpose of scraping the wax liquid at a fixed time.

[0046] The moving assembly includes a bar seat 61, a rotating shaft 62, a belt 67, a power device 63 and a slide 65, wherein the power device 63 is a motor.

[0047] The strip seat 61 is fixed on the housing 4 and arranged along the length direction of the high temperature resistant glass 5; the total length of the strip seat 61 is equal to or longer than the length of the high temperature resistant glass 5. There are two rotating shafts 62, which are rotatably connected to the two ends of the strip seat 61; the belt 67 is connected to the two rotating shafts 62 and is sleeved on the strip seat 61; the upper and lower ends of the strip seat 61 are provided with belt grooves 610, and the belt 67 is arranged in the belt grooves 610. The power device 63 is arranged on the rotating shaft 62, driving the rotating shaft 62 to rotate, and the belt 67 is driven to rotate during the rotation of the rotating shaft 62; the slide 65 is seated on the strip seat 61 and fixedly connected to the belt 67; rollers 66 are arranged on both sides of the bottom of the slide 65, and side slide grooves 64 are opened on both sides of the strip seat 61, and the rollers 66 roll in the side slide grooves 64.

[0048] During the rotation of the belt 67, the belt 67 carries the slide 65 and moves from one end of the strip seat 61 to the other end. During the movement, the scraping assembly scrapes the wax liquid on the high temperature resistant glass 5. After scraping, the power device 63 rotates in the reverse direction, driving the belt 67 to rotate in the reverse direction, so that the slide 65 and the scraping assembly are reset to the origin.

[0049] The scraping assembly includes a support plate 68 and at least one scraper plate 69. The top surface of the support plate 68 is arc-shaped. The arc-shaped design enables the wax liquid to slide down through the arc surface when it drops on the support plate 68, and the wall wax liquid solidifies on the support plate 68. The support plate 68 is suspended on the top of the high-temperature resistant glass, and the support plate 68 is fixed on the slide 65. The scraper plate 69 is fixed on the support plate 68, and the scraper plate 69 contacts the high-temperature resistant glass.

[0050] When the slide 65 moves, it drives the support plate 68 and the scraper plate 69 to move horizontally on the high temperature resistant glass 5 to scrape the wax liquid on the high temperature resistant glass 5. The scraped wax liquid slides down and out of the housing 4 to prevent the weight of the housing 4 from increasing continuously. The purpose is to prevent the universal hinge connected to the infrared baking lamp 2 from changing direction as the weight of the housing 4 increases, resulting in a change in the direction of the hot air, so that the hot air cannot be accurately blown on the car door and the door pillar.

[0051] The air distribution component 7 is arranged at the opening of the housing 4, and blows the hot air out through the opening evenly and in different directions, so that the hot air can be blown out non-centrally and evenly on the car door and the door pillar.

[0052] The air distribution assembly 7 includes an air flow guide assembly distributed around the opening and an air distribution plate assembly in the middle. The air flow guide assembly guides the hot air to the surroundings to expand the blowing area of ​​the hot air. The air distribution plate assembly in the middle can make the air flow blow out evenly, preventing the hot air from being concentrated when blowing out, resulting in uneven heating of the door and door pillars.

[0053] The air distribution plate group includes a central frame 73 fixed on the housing 4, and an inner mesh plate 75 and an outer mesh plate 74 are fixed to the inner and outer sides of the central frame 73 respectively. The air flow guide assembly includes an upper grille 71, a second side grille 77, a lower grille 72 and a first side grille 76 arranged clockwise around the air distribution plate group. Among them, the upper grille 71 is arranged upwardly inclined; the lower grille 72 is arranged downwardly inclined; the first side grille 76 and the second side grille 77 are arranged to be inclined to the left and right sides.

[0054] Working principle: The infrared lamp 2 is irradiated on the door and door pillar of the car shell, and the infrared lamp generates heat when it works. The fan 8 works, and the heat generated by the infrared lamp 2 is converted into hot air and blown out through the opening, and blown on the door and door pillar of the car shell. When the hot air is blown out through the opening, the hot air is blown out through the opening evenly and in different directions. The hot air can be blown out non-centrally and blown evenly on the door and door pillar. During operation, the wax liquid dripping from the door and door pillar drips on the high-temperature resistant glass 5 on the car shell 4, and the power device 63 drives the rotating shaft 62 to rotate. During the rotation of the rotating shaft 62, the belt 67 is driven to rotate. The belt 67 carries the slide 65 along one end of the strip seat 61 to the other end. During the movement, the bracket plate 68 and the scraper plate 69 are driven to move horizontally on the high-temperature resistant glass 5 to scrape the wax liquid on the high-temperature resistant glass 5. The scraped wax liquid slides down and out of the shell 4.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
