Detailed Embodiment

[0026] The following details the present utility model with specific embodiments.

[0027] A detection device for particles and firmware additives inside a filter rod of this application is mainly applied to various filters, including cigarette products such as transparent filters and paper non-transparent filters, and is used to determine whether the phase of the particles and fixing parts inside them in the corresponding installation cavity is accurate and whether there is any contamination on the surface, so as to continuously collect and detect information on the products on the production line and optimize the product quality control plan.

[0028] In this application, the main structure of the detection device for particles and firmware additives inside the filter rod is as Figure 1As shown, it includes an installation box 1, and an infrared vision detection device 2, a visible light vision detection device 3, and a detachable guide component 4 which are sequentially arranged inside the installation box 1 from top to bottom;

[0029] Among them, the installation box is used to protect and isolate internal devices and components. Since it contains light sources and cameras, etc., using the installation box for isolation and protection can improve the detection effect and prevent external light sources from affecting the imaging quality. At the same time, it can avoid external impurities and dust from entering the internal cavity, causing lens blur and affecting equipment performance.

[0030] As a convenient implementation solution, the installation box 1 is surrounded by a plurality of shell plates; in order to ensure that the relative position of the internal light source and the camera is fixed, a light source support seat 10 for supporting and fixing the infrared light source 20 and the visible light source 30 is provided on the inner wall of the installation box 1. The camera adopts an industrial camera, which is fixed to the inner wall of the installation box through its own bolt holes and screws, without additional settings;

[0031] In order to facilitate docking with the internal structure and the external production line, a connection hole facing the guide tube 42 is provided on the inner wall of the installation box 1, and a positioning piece for positioning the guide tube 42 is installed in the connection hole. The detachable guide assembly 4 is a detachable structure, so that the transparent (usually glass) guide tube 41 inside can be replaced, and docking observation is convenient through the connection hole and the positioning piece. The side of the positioning piece facing the guide tube 42 can be set to a cone hole structure with a cone bottom diameter larger than the tube hole diameter, so as to facilitate the entry and exit of the tested product.

[0032] like Figure 2 , Figure 3 , Figure 4 As shown, the detachable guide assembly 4 includes a guide seat 40, a fixing tube 41, and a material guide tube 42; the guide seat 40 is a horizontally arranged L-shaped structure, including a guide arm 400 and a reflection arm 401;

[0033] The guide arm 400 is provided with a first mounting hole 40a and a first observation hole 40b which penetrate the arm body and are connected to each other; the first mounting hole 40a is dug out in the horizontal direction, and the first observation hole 40b is dug out in the vertical direction; a reflector 43 is provided on the side of the reflective arm 401 facing the fixed tube 41;

[0034] The material guide tube 42 is made of transparent material. One end of the material guide tube 42 is inserted into the first mounting hole 40a and passes through the intersection of the first mounting hole 40a and the first observation hole 40b, and the other end is inserted into the fixing tube 41. The fixing tube 41 is located on one side of the reflection arm 401, and a reflection hole 41a facing the reflection arm 401 is dug out on the fixing tube 41.

[0035] One end of the fixing pipe 41 is inserted into the first mounting hole 40 a and does not pass through the intersection of the first mounting hole 40 a and the first observation hole 40 b .

[0036] There is an installation opening in the middle of the installation box 1; the detachable guiding assembly 4 further includes a connecting plate 45, and the connecting plate 45 is detachably buckled at the installation opening through a bolt group; an installation groove for fixing the guiding seat 40 is provided on the inner side plate surface of the connecting plate 45; the guiding arm 400 is inserted into the installation groove; filter rod inlet and outlet ports that are directly communicated with the material guiding pipe 42 are respectively provided at the bottom of the installation box 1 and the installation groove.

[0037] The detachable guiding assembly 4 is used to control the path of products such as the filter tips to be measured passing through the inside of the detection device, and at the same time control the irradiation area and the acquisition area of the camera and the light source, and guide the light path through the internal channels and specular reflection, so as to control the acquisition area, avoid mutual interference of the light sources, and at the same time simplify the replacement and maintenance method of internal structures such as the material guiding pipe.

[0038] Among them, the internal channels of the guiding seat 40 cooperate with the material guiding holes to enable the product to smoothly pass through the detection area in the horizontal direction. After that, the guiding seat and the fixed pipe form two different optical paths to realize information acquisition in different areas, and the guiding seat and the fixed pipe simultaneously form a positioning and supporting structure for the material guiding pipe 42.

[0039] The infrared vision detection device 2 includes an infrared light source 20 and a first camera 21; the infrared light source 20 is located below the guiding seat 40, the first camera 21 is located above the guiding seat 40, and the light of the infrared light source 20 passes through the material guiding pipe 42 through the first observation hole 40b and then shoots towards the first camera 21;

[0040] The visible light vision detection device 3 includes a visible light source 30 and a second camera 31; the visible light source 30 is perpendicular to the material guiding pipe 42, the second camera 31 is located below the guiding seat 40, and the light of the visible light source 30 passes through the reflection hole 41a and shoots towards the reflecting mirror 43, and is refracted by the reflecting mirror 43 to the lens of the second camera 31.

[0041] For traditional transparent filter tips, the internal visual information can be directly obtained by a normal camera based on natural light imaging, and then the internal phase and surface conditions can be collected this time. However, for non-transparent filter tip products such as paper filter tips, although the thickness is very small, natural light cannot directly penetrate, and the camera cannot only obtain the phase and surface information of the internal structure. In this application, to meet the requirements of the above different situations, two light source schemes of natural light and infrared light are adopted. While using infrared light to meet the information acquisition of the aforementioned non-transparent products, it can also be used for further analysis of internal details, meet the quality detection requirements of different detection contents and different products, and improve the versatility of the device.

[0042] In particular, in order to shorten the optical path of the information collection light path, optimize the device structure, reduce interference, and at the same time compress the volume of the device itself so that it can be better connected to the existing production line, the infrared light source 20 in this embodiment emits light vertically from bottom to top toward the first observation hole 40b; the lens of the first camera 21 is vertically directed from bottom to top toward the first observation hole 40b; the reflective hole 41a is dug out horizontally, and the visible light source 30 is emitted into the reflective hole 41a in the horizontal direction and penetrates the guide tube 42 and then emitted to the reflector 43.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
