[0029] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example:

[0031] See also Figure 1 , Figure 1 A schematic structural diagram of an infrared camera module 10 provided in an embodiment of the present invention applied to a sorting device 1000.

[0032] The embodiment of the present invention provides an infrared camera module 10, which has the characteristics of small size, convenient spatial layout, and low cost. The infrared camera module 10 can be applied to the sorting mechanism 100 of the sorting device 1000, and of course, the infrared camera module 10 can also be used independently. When the infrared camera module 10 is applied to the sorting device 1000, the infrared camera module 10 is arranged in the sorting mechanism 100, so as to identify the infrared light reflected by the material at the viewing point position in the sorting mechanism 100 through the infrared camera module 10, so that the sorting mechanism 100 can determine whether to reject the corresponding material. Since the sorting device 1000 adopts the infrared camera module 10 provided by the embodiment of the present invention, the sorting device 1000 also has the characteristics of small size, convenient spatial layout, and low cost.

[0033] The following will specifically introduce the structure, working principle and beneficial effects of the infrared camera module 10 provided by the embodiment of the present invention.

[0034] See also Figure 2 and Figure 3 , Figure 2 A schematic structural diagram of an infrared camera module 10 provided in an embodiment of the present invention. Figure 3 A schematic diagram of the three-dimensional structure of an infrared camera module 10 provided in an embodiment of the present invention.

[0035] The infrared camera module 10 includes an infrared recognition module 11, a first switching driver 12, a first filter 16 and a second filter 17. The infrared recognition module 11 is used to recognize the infrared light reflected by the material at the viewing point in the sorting mechanism 100, and the first switching driver 12 is connected to the first filter 16 and the second filter 17, and the first switching driver 12 can drive the first filter 16 and the second filter 17 to move, so as to change the position of the first filter 16 and the second filter 17, so that the first filter 16 or the second filter 17 corresponds to the infrared recognition module 11. In this way, the infrared light reflected by the material recognized by the infrared recognition module 11 is the infrared light of the corresponding band after the corresponding filter is transmitted. Thus, by switching the filter, one infrared recognition module 11 can recognize infrared light of multiple different bands, and its volume is small, which is convenient to be set in the sorting mechanism 100, and the cost is low.

[0036] The common existing infrared sorting method is to obtain more infrared signal values ​​of materials in different bands to sort the materials. Generally, this method continues to increase infrared cameras, which has high requirements on spatial layout and structure, and may even be difficult to layout. In addition, the required material cost is also high.

[0037] It should be noted that, in the present embodiment, the infrared camera module 10 also includes a third filter 18, and the first filter 16, the second filter 17 and the third filter 18 are arranged in sequence to move under the drive of the first switching drive member 12, so that different filters correspond to the infrared recognition module 11, so as to transmit infrared light of different bands to the infrared recognition module 11 through different filters, so as to facilitate recognition by the infrared recognition module 11.

[0038] In addition, the infrared camera module 10 may further include a filter bracket 13, and the first filter 16 or the second filter 17 is sequentially mounted on the filter bracket 13, the filter bracket 13 is connected to the first switching drive member 12, thereby connecting the filter and the first switching drive member 12, and the third filter 18 is also mounted on the filter bracket 13, such as Figure 2 and Figure 3 Of course, in other embodiments, when the types of materials to be sorted increase, the number of filters may also be increased, such as 4 or 5, etc., which is not limited in this embodiment.

[0039] In addition, in the present embodiment, the first switching drive member 12 is a linear motion drive structure, and the first switching drive member 12 can drive the first filter 16, the second filter 17 and the third filter 18 to reciprocate along a straight line, so that the first filter 16, the second filter 17 or the third filter 18 corresponds to the infrared recognition module 11 to complete the action of switching the filters. Its structure is simple and its volume is small.

[0040] In other embodiments, the first switching drive member 12 may also be a rotational motion drive structure, and the first switching drive member 12 can drive the first filter 16, the second filter 17 and the third filter 18 to rotate, so that the first filter 16, the second filter 17 or the third filter 18 corresponds to the infrared recognition module 11, thereby realizing the action of switching the filter, which has less vibration during operation and a simple structure.

[0041] Furthermore, the infrared camera module 10 may also include an infrared lens 15, which is arranged on the incident path of the infrared recognition module 11, so that the infrared light is incident on the infrared recognition module 11 through the infrared lens 15, thereby improving the stability of the infrared camera module 10 in recognizing infrared light.

[0042] Moreover, in this embodiment, the first switching drive member 12 can drive the first filter 16 and the second filter 17 to move between the infrared lens 15 and the infrared recognition module 11, so that the infrared light passes through the infrared lens 15 and the first filter 16 or the second filter 17 in sequence before entering the infrared light.

[0043] In other embodiments, the first filter 16 and the second filter 17 may also be roughly located at the end of the infrared lens 15 away from the infrared recognition module 11, and the first switching drive 12 can drive the first filter 16 and the second filter 17 to move to the end of the infrared lens 15 away from the infrared recognition module 11, so that the infrared light is transmitted through the first filter 16 or the second filter 17 in turn, and then incident on the infrared recognition module 11 after the infrared lens 15.

[0044] In addition, in other embodiments, the infrared camera module 10 may also include a second switching drive, a fourth filter and a fifth filter, the second switching drive is connected to the fourth filter and the fifth filter, and the fourth filter and the fifth filter are approximately located at one end of the infrared lens 15 away from the infrared recognition module 11, and the second switching drive can drive the fourth filter and the fifth filter to move so that the fourth filter or the fifth filter moves between the infrared lens 15 and the infrared recognition module 11, thereby transmitting the incident infrared light to the infrared recognition module 11 through the fourth filter or the fifth filter, so that the purpose of increasing the type of materials recognized by the infrared camera module 10 can be achieved by switching the first filter 16, the second filter 17, the third filter 18, the fourth filter and the fifth filter.

[0045] The working principle of the infrared camera module 10 provided in the embodiment of the present invention is:

[0046] The infrared camera module 10 includes an infrared recognition module 11, a first switching drive 12, a first filter 16 and a second filter 17. The infrared recognition module 11 is used to recognize the infrared light reflected by the material at the viewing point in the sorting mechanism 100, and the first switching drive 12 is connected to the first filter 16 and the second filter 17, which can drive the first filter 16 and the second filter 17 to move, so as to change the position of the first filter 16 and the second filter 17, so that the first filter 16 or the second filter 17 corresponds to the infrared recognition module 11. In this way, the infrared light reflected by the material recognized by the infrared recognition module 11 is the infrared light of the corresponding band after the corresponding filter is transmitted. Thus, by switching the filter, one infrared recognition module 11 can recognize infrared light of multiple different bands, and its volume is small, and the cost is low, so it is easy to be set in the sorting mechanism 100.
