Description

Technical Field

[0001] This utility model relates to the field of sorting technology, and in particular to infrared camera modules, sorting mechanisms and sorting devices. Background Technology

[0002] An infrared camera module, sorting mechanism, and sorting device, with application number CN202120752983.X, relates to the field of sorting technology. The infrared camera module includes an infrared recognition module, a first switching drive, a first filter, and a second filter. The infrared recognition module is used to identify the infrared light reflected by material located at a viewing position within the sorting mechanism. The first switching drive is connected to the first and second filters and can drive the first and second filters to move, so that the first or second filter corresponds to the infrared recognition module, thereby transmitting infrared light of the corresponding wavelength to the infrared recognition module through the corresponding filter. This infrared camera module, sorting mechanism, and sorting device are characterized by their small size, ease of space layout, and low cost.

[0003] Although the above-mentioned technologies can achieve the detection function of multiple characteristic bands by a single infrared recognition module through the combined application of multi-band filters, in practical applications, when the optical performance of the filters deteriorates due to mechanical damage, material aging, or surface contamination, the above-mentioned technologies require complete disassembly for maintenance and replacement. This is complicated, time-consuming, and leads to increased equipment maintenance costs, decreased operating efficiency, and reduced practicality and economy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an infrared camera module, a sorting mechanism and a sorting device.

[0005] Embodiments of this utility model provide an infrared camera module, a sorting mechanism, and a sorting device, including:

[0006] An infrared camera assembly; the infrared camera assembly includes a rectangular bracket, an infrared recognition module, a rotary cylinder and a turntable. The infrared recognition module and the rotary cylinder are both fixedly mounted on the rectangular bracket. The turntable is fixedly mounted on the output end of the rotary cylinder. The turntable is provided with multiple mounting slots. A light-transmitting hole is provided through the inner side of the mounting slot. A filter is provided in the mounting slot.

[0007] A fixing component for fixing a filter.

[0008] Furthermore, the infrared camera assembly also includes an infrared lens, which is disposed on the incident path of the infrared recognition module so that infrared light is incident on the infrared recognition module through the infrared lens.

[0009] Furthermore, the fixing component includes an annular frame, a first magnetic ring, and a second magnetic ring. The filter is fixedly disposed within the annular frame, the first magnetic ring is fixedly disposed within the annular frame, and the second magnetic ring is fixedly disposed within the mounting groove.

[0010] Furthermore, a heating wire is fixedly mounted on the rectangular support, and the heating wire is configured in conjunction with the filter.

[0011] Furthermore, a sorting mechanism is characterized by including the aforementioned infrared camera module.

[0012] Furthermore, a sorting device is characterized by comprising the aforementioned sorting mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. An infrared camera assembly and a mounting assembly are included. During operation, a rotating cylinder drives multiple different filters to rotate, allowing a single infrared recognition module to identify multiple infrared light bands by switching between filters. To replace the filter, simply push it out of its mounting slot; then place the new filter back into the slot and attach the first and second magnetic rings to secure it. The operation is simple and convenient, reducing maintenance costs and improving work efficiency and practicality.

[0015] 2. A heating wire is installed to heat the filter, keeping its temperature above the dew point. This effectively prevents condensation on the filter in environments with high humidity or significant temperature differences, thus preventing reduced light transmittance and image quality loss caused by condensation and significantly improving system stability.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown, this utility model embodiment proposes an infrared camera module, a sorting mechanism, and a sorting device, including:

[0023] Infrared camera assembly; The infrared camera assembly can be applied to the sorting mechanism of a sorting device. The infrared camera assembly is set inside the sorting mechanism to identify the infrared light reflected by the material at the viewpoint position inside the sorting mechanism, so that the sorting mechanism can determine whether to reject the corresponding material.

[0024] The infrared camera assembly includes a rectangular bracket 10, an infrared recognition module 12, a rotary cylinder 2, and a turntable 3. The infrared recognition module 12 and the rotary cylinder 2 are both fixedly mounted on the rectangular bracket 10. The infrared recognition module 12 is used to identify the infrared light reflected by the material located at the viewing point in the sorting mechanism. The turntable 3 is fixedly mounted on the output end of the rotary cylinder 2, and the rotary cylinder 2 is used to drive the turntable 3 to rotate. The turntable 3 is provided with multiple mounting slots 4, and a light-transmitting hole 5 is provided through the inner side of the mounting slot 4 to transmit light. A filter 7 is provided in the mounting slot 4, and the mounting slot 4 is used to install the filter 7.

[0025] The infrared camera assembly also includes an infrared lens 1, which is positioned on the incident path of the infrared recognition module 12 so that infrared light is incident on the infrared recognition module 12 through the infrared lens 1, thereby improving the stability of infrared light recognition.

[0026] A heating wire 11 is fixedly mounted on a rectangular bracket 10. The heating wire 11 is configured to work in conjunction with the filter 7. The heating wire 11 is positioned close to the filter 7 and is used to heat the filter 7. In environments with high humidity or large temperature differences (such as cold chain sorting or outdoor nighttime operations), the surface temperature of the filter 7 may be lower than the ambient dew point temperature, causing water vapor to condense into fog droplets. In this case, the heating wire 11 actively heats up the filter to ensure that the edge temperature of the filter 7 is always higher than the dew point, thus preventing condensation from affecting the light transmittance and imaging quality.

[0027] A fixing assembly is used to fix the filter 7. The fixing assembly includes an annular frame 6, a first magnetic ring 8, and a second magnetic ring 9. The filter 7 is fixedly disposed within the annular frame 6, which is disposed within the mounting groove 4. The first magnetic ring 8 is fixedly disposed within the annular frame 6, and the second magnetic ring 9 is fixedly disposed within the mounting groove 4. The outer sides of the first magnetic ring 8 and the second magnetic ring 9 are opposite magnetic poles, and they are attracted to each other, so that the annular frame 6 can be attracted to the second magnetic ring 9 through the first magnetic ring 8, thereby fixing the filter 7 within the mounting groove 4.

[0028] A sorting mechanism, including the aforementioned infrared camera module.

[0029] A sorting device, comprising the sorting mechanism described above.

[0030] The detailed working process of this utility model is as follows:

[0031] 1. In use, the rotary cylinder 2 can drive the turntable 3 to rotate, which in turn drives multiple different filters 7 to rotate, thereby changing the position of multiple filters 7. This allows multiple filters 7 to correspond to the infrared recognition module 12, so that the infrared light reflected by the material and recognized by the infrared recognition module 12 is the infrared light of the corresponding wavelength after being transmitted through the corresponding filter 7. Thus, by switching the filters 7, one infrared recognition module 12 can recognize multiple infrared light of different wavelengths.

[0032] 2. When replacing, push the filter 7 outward to separate the first magnetic ring 8 and the second magnetic ring 9 on the annular frame 6, and then remove the filter 7; then place the replaced filter 7 into the mounting slot 4, and make the first magnetic ring 8 and the second magnetic ring 9 on the annular frame 6 attract each other to fix the filter 7.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
