In the above curing method, since the heated air does not circulate effectively in the curing furnace, the temperature distribution in the curing furnace is uneven and the curing effect is relatively poor.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a curing furnace. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a curing furnace, which can solve the problem that the curing effect of the lens coating is relatively poor due to the uneven temperature distribution in the curing furnace.

Detailed Embodiments

[0028] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figures 1 - 3 , the curing furnace in an embodiment of the present utility model includes a first box body 1, a second box body 2, a heating assembly 3, a gas transmission assembly 4, a lifting assembly 5, and a conveying assembly 6. The heating assembly 3 and the gas transmission assembly 4 are arranged in cooperation with the first box body 1 and the second box body 2. The lifting assembly 5 is used to drive the first box body 1 and the second box body 2 to move to a first position where they are in contact with each other (such as Figure 2 ), or move to a second position where they are away from each other (such as Figure 1 ). The conveying assembly 6 is used to convey the lens coating to be cured.

[0030] Referring to Figure 2 and Figure 3 , when the first box body 1 and the second box body 2 are in the first position where they are in contact with each other, a sealed curing cavity is formed between the first box body 1 and the second box body 2. The gas transmission assembly 4 is used to drive the air heated by the heating assembly 3 to circulate through the inner cavity of the first box body 1, the curing cavity, and the inner cavity of the second box body 2. In this embodiment, the surface of the second box body 2 close to the first box body 1 is recessed to form the above-mentioned curing cavity, and the lens to be cured is located in the curing cavity.

[0031] Referring to Figure 3 , the heating assembly 3 includes a heating box 31 installed in the second box body 2, and heating wires 32 installed in the heating box 31. The heating box 31 is provided with an air inlet and an air outlet. The air inlet is communicated with the curing cavity, and the air outlet is communicated with the gas transmission assembly 4. Specifically, a communication pipeline 7 is arranged between the heating box 31 and the curing cavity.

[0032] Referring to Figure 4 , the gas transmission assembly 4 includes a gas guiding member 41, a first pipeline 42, and a second pipeline 43. The air inlet end of the gas guiding member 41 is communicated with the air outlet of the heating box 31; the first pipeline 42 is installed in the first box body 1 to communicate the inner cavity of the first box body 1 with the outside; the second pipeline 43 is installed in the second box body 2 to communicate the air outlet end of the gas guiding member 41 with the outside. When the first box body 1 and the second box body 2 are in the first position, the first pipeline 42 and the second pipeline 43 are communicated. In this embodiment, the gas guiding member 41 can be a blower.

[0033] Therefore, when the curing furnace is in use, the heating wire 32 is energized to heat the air in the heating box 31. Then, the air guiding member 41 guides the heated air out of the heating box 31, and successively passes through the second pipeline 43, the first pipeline 42, the inner cavity of the first box body 1, the curing cavity, and finally returns to the heating box 31 to continue heating the air. Among them, since the air is heated repeatedly, the balance of the air temperature can be ensured; at the same time, since the air circulates in the curing furnace, the uniformity of the temperature distribution in the curing cavity can be ensured; finally, since the hot air continuously blows from top to bottom onto the surface of the lens, the curing effect of the coating can be ensured.

[0034] Furthermore, the inner diameters of the first pipeline 42 and the second pipeline 43 are the same. Therefore, when the first box body 1 and the second box body 2 are in the first position where they are in contact with each other, the first pipeline 42 and the second pipeline 43 can be effectively aligned at this time, so as to ensure the air circulation. In this embodiment, a sealing strip (not shown in the figure) is fixed on one side of the first box body 1 and / or the second box body 2 that are close to each other. By setting the sealing strip, the sealing performance of the curing cavity can be further ensured, thereby reducing the heat loss in the curing furnace.

[0035] Refer to Figure 1 and Figure 3 , the lifting assembly 5 includes a driving member 51 and a lifting rod 52. The driving member 51 is installed in the second box body 2. One end of the lifting rod 52 is fixedly connected to the first box body 1, and the other end is in transmission connection with the driving member 51. A through hole for the lifting rod 52 to pass through is provided at the corresponding position of the second box body 2. The driving member 51 drives the lifting rod 52 to lift, so that the first box body 1 and the second box body 2 can be respectively in the first position and the second position. For example, the driving member 51 can be a cylinder, and the cylinder drives the lifting rod 52 to move so that the first box body 1 approaches or moves away from the second box body 2. It can be understood that in other embodiments, a transmission member can also be additionally provided to convert the movement of the driving member 51 into the lifting movement of the lifting rod 52.

[0036] Among them, compared with the flip design between the first box body 1 and the second box body 2, in this embodiment, a lifting design is adopted between the first box body 1 and the second box body 2. The above design method increases the operation space of the relevant staff inside the curing cavity and improves the convenience of cleaning the inside of the curing furnace. When a flip design is adopted between the first box body 1 and the second box body 2, the connection part between the two is relatively difficult to clean.

[0037] Refer to Figure 3, a filter element 8 is installed on one side of the first box body 1 close to the second box body 2, and the pipe orifice position of the first pipe 42 inside the first box body 1 is located on the side of the filter element 8 away from the second box body 2. The filter element 8 can effectively filter the air, thereby reducing the dust impurities that may exist in the air, and further ensuring that the coating on the lens is not contaminated. In this embodiment, since the air circulates in the curing furnace, the air can flow through the filter element 8 multiple times, so that it can be filtered as many times as possible to ensure the cleanliness of the air.

[0038] Referring to Figure 4 and Figure 5 , a conveying assembly 6 for conveying workpieces is installed in the curing cavity of the second box body 2. The conveying assembly 6 includes a plurality of conveying rollers 61 rotatably installed on the inner wall of the curing cavity, and a conveying mesh belt 62 rollingly connected to the plurality of conveying rollers 61. When the conveying rollers 61 rotate, the conveying mesh belt 62 can be driven to move, so as to drive the lens located on the conveying mesh belt 62 to move. Among them, since the conveying mesh belt 62 is provided with mesh holes, it is more convenient for the circulation of hot air.

[0039] When the curing furnace of this embodiment is in use, the lifting assembly 5 drives the first box body 1 and the second box body 2 to be in the first position, so that the first box body 1 and the second box body 2 are communicated through the first pipe 42 and the second pipe 43. Then, the heating wire 32 is started to heat the air in the heating box 31, and the heated air is circulated in the curing furnace through the air guiding member 41. The conveying assembly 6 conveys the lens in the curing cavity, so as to complete the curing of the coating on the lens surface.
