Description

Technical Field

[0001] This utility model mainly relates to the technical field of automobile rearview mirror assembly, specifically a hot drying device for assembling automobile rearview mirror housings. Background Technology

[0002] Car rearview mirrors are located on the left and right sides of the front of the car. They reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas. They act as a "second eye," expanding the driver's field of vision.

[0003] In the existing technology, during the assembly process of car rearview mirrors, the rearview mirror housing needs to be cleaned before assembly to ensure the cleanliness of the rearview mirror housing during subsequent assembly and to avoid dust pollution of the assembly environment. After cleaning, the rearview mirror housing needs to be dried using drying equipment. However, the existing drying equipment does not dry the rearview mirror housing evenly or effectively, and the evaporated water vapor cannot be removed in time. As a result, the water vapor re-condenses on the rearview mirror when it cools down, affecting subsequent assembly. Therefore, there is an urgent need for a hot drying equipment for rearview mirror housing assembly that integrates heating, air drying, and cooling to solve the problem of incomplete moisture removal in the existing technology.

[0014] This utility model discloses a hot drying device for assembling automotive rearview mirror housings. During use, the rearview mirror housings are conveyed forward via a mesh belt conveyor, passing through a drying unit and a cooling unit in sequence. In the drying unit, a heating fan draws in outside air into the air intake chamber and blows it into the hot air chamber. Heating wires heat the air in the hot air chamber to a specified temperature, and then the hot air is discharged into the hot drying chamber. The moisture on the rearview mirror housing evaporates, and the hot air carrying the moisture enters the hot exhaust pipes at both ends and is discharged away. The hot exhaust valve controls the exhaust speed. The dried rearview mirror housings enter the cooling unit, where four sets of cooling fans blow air, and the lower cold exhaust pipe draws in air to create air circulation and accelerate cooling. Finally, the dried and cooled rearview mirror housings flow to the next station.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0025] See attached document Figure 1-4 This embodiment of a hot drying device for assembling automotive rearview mirror housings includes a mesh belt conveyor 100, a drying unit 200, and a cooling unit 300. The mesh belt conveyor 100 passes through the interiors of the drying unit 200 and the cooling unit 300. The drying unit 200 and the cooling unit 300 are fixed close to each other. The drying unit 200 includes an upper drying oven 210, a lower drying oven 220, a hot drying cavity 240, and an exhaust assembly 230. The upper drying oven 210 and the lower drying oven 220 are symmetrically installed to form the hot drying cavity 240. The exhaust assembly 230 is fixedly installed above the upper drying oven 210.

[0026] The upper oven 210 of this embodiment includes an air inlet shell 211, a first partition 212, a second partition 213, a third partition 214, an air inlet cavity 215, a hot air cavity 216, a heating fan 217, a heating wire 218, and a bracket 219. The first partition 212 is fixed inside the air inlet shell 211 to form the air inlet cavity 215. The second partition 213 has multiple sets that are sequentially fixed below the first partition 212. The third partition 214 is connected to the side of the air inlet shell 211 and is connected to the lower part of the second partition 213 to form the hot air cavity 216. The multi-cavity design ensures that the cavities do not affect each other and the heating is more uniform.

[0027] In this embodiment, multiple heating fans 217 are sequentially arranged on the first partition 212. Each of the multiple hot air chambers 216 is equipped with an electric heating wire 218. The electric heating wire 218 is fixed to the third partition 214 by a bracket 219. The electric heating wire 218 heats the air, and the heating fans 217 circulate the air, thus satisfying the two major factors of water evaporation.

[0028] The exhaust assembly 230 in this embodiment includes a hot exhaust pipe 231 and a hot exhaust valve 232. One end of the hot exhaust pipe 231 is fixedly installed inside the upper drying oven 210, and the other end is connected to an exhaust pump. The hot exhaust valve 232 is installed on the hot exhaust pipe 231. The exhaust pipe removes the water vapor inside the hot drying chamber 240 in real time, thereby accelerating the drying process.

[0029] The cooling unit 300 in this embodiment includes an upper cooling box 310, a lower cooling box 320, a cold exhaust duct 330, and a cold exhaust valve 340. The upper cooling box 310 and the lower cooling box 320 are symmetrically fixed. The cold exhaust duct 330 is connected to the lower cooling box 320, and the cold exhaust valve 340 is installed on the cold exhaust duct 330.

[0030] In this embodiment, the upper oven 210 and the lower oven 220 are symmetrically designed. Temperature sensors are installed on the sides of both the upper oven 210 and the lower oven 220. The temperature sensors monitor the temperature inside the hot drying cavity 240 in real time to prevent the rearview mirror housing from being damaged by excessive temperature.

[0031] In this embodiment, the air inlet housing 211 has an air inlet hole on the upper part to facilitate the entry of external air into the air inlet cavity 215.

[0032] The specific operation of this utility model is as follows: During use, the rearview mirror housing is conveyed forward by the mesh belt conveyor line 100, passing through the drying unit 200 and the cooling unit 300 in sequence. The heating fan 217 in the drying unit 200 draws outside air into the air inlet cavity 215 and blows it into the hot air cavity 216. The heating wire 218 heats the air in the hot air cavity 216 to the specified temperature. Then the hot air is discharged into the hot drying cavity 240, and the moisture on the rearview mirror housing evaporates. The hot air carrying the water vapor enters the hot exhaust pipes 231 at both ends and is discharged away. The hot exhaust valve 232 controls the exhaust speed. The dried rearview mirror housing enters the cooling unit 300, where four sets of cooling fans blow air and the lower cold exhaust pipe 330 draws air to form air circulation, accelerating the cooling. Finally, the dried and cooled rearview mirror housing flows to the next station.

[0033] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
