Description

Technical Field

[0001] The patent of this invention relates to the technical field of low-temperature heating non-combustion product production, and specifically to a light inspection method and device suitable for quantitative analysis of the filling amount of the smoking section of an aerosol generating product. Background Art

[0002] The smoking sections of aerosol generating products currently on the market mainly include granular, tobacco or thin sheet, and paste-like smoking materials. Aerosol generating products are new tobacco products. Their appearance structure, molding process, and smoking mechanism are different from traditional cigarettes. Due to the particularity of the product, there are currently no clear standard requirements, resulting in uneven quality of aerosol generating products on the market, especially for the filling amount of aerosol generating products with granular and paste-like smoking materials. There is a lack of corresponding inspection methods. The amount of aerosol generating source material filling will seriously affect the smoking effect of the aerosol generating product and affect the sensory smoking quality. In the prior art, the filling amount of aerosol generating products is mainly evaluated by weighing, but due to the complex structure of aerosol generating products and the large number of materials used, the weight fluctuates greatly, and the manual weighing method is labor-intensive and inefficient.

[0003] Light inspection is an important means of quality inspection. It is currently mainly used in the pharmaceutical, food, chemical, pesticide and other industries to test ampoules, vials and oral liquids.

[0004] CN 208969019 U discloses a light inspection machine, including a shock-absorbing foot, a light inspection chamber arranged on the shock-absorbing foot, and a bearing device arranged in the light inspection chamber, wherein the bearing device includes a motor, a registration and protection device, a connecting rod and a chuck, wherein the motor is arranged in the light inspection chamber and installed at the bottom of the light inspection chamber, wherein the transmission shaft of the motor is connected to the geometric center of the light inspection table, wherein the center position of the upper surface of the light inspection table is provided with a first inspection lamp, wherein the outer side of the inspection table is provided with a bottle placement groove surrounding the first inspection lamp, wherein the bottom of the bottle placement groove is provided with a second inspection lamp and a warning lamp, wherein the connecting rod is arranged on the light inspection table, wherein the connecting rod is provided with a cavity running through the entire rod body, wherein a first spring is arranged in the connecting rod cavity, wherein one end of the first spring is connected to the light inspection table and the other end is connected to the chuck. The light inspection machine mainly solves the problems of manual chuck, unstable bottle clamping, and inspection shadow blind area of ​​the light.

[0005] CN 208537445 U discloses a horizontal light inspection box, comprising a longitudinal light inspection box electrically connected to a conveyor chain motor and arranged longitudinally with a barrel conveyor chain, and a transverse light inspection box arranged parallel to the barrel conveyor chain, the transverse light inspection box being fixedly connected to the longitudinal light inspection box, a fixed bracket being arranged below the transverse light inspection box, the fixed bracket being connected to the barrel conveyor chain through a rotating rocker, a telescopic screw and a locking screw connected by transmission, the longitudinal and transverse light inspection boxes are both provided with LED parallel backlight sources, and at least two barrel roller brackets are arranged on the LED parallel backlight sources of the longitudinal and transverse light inspection boxes.

[0006] CN 203299141U discloses a light inspection machine, comprising a light inspection box, a light source is arranged in the light inspection box, a transparent light inspection workbench is arranged on the top of the light inspection box, a light shielding plate is arranged on one side of the light inspection box, the light shielding plate is respectively connected to the light inspection workbench and the side plate of the light inspection box, and the light source is located below the light shielding plate.

[0007] In summary, current light inspection devices are mainly used to check whether there are suspended liquids in the liquids in ampoules, vials, and oral liquids. Therefore, the light source of the light inspection device is located directly below the test sample. The light source passes through the test sample, and the inspector observes whether there are suspended impurities in the test sample bottle.

[0008] However, the existing light inspection device is complex, costly, and requires a small amount of samples, and cannot meet the needs of industrial production. More importantly, the existing light inspection device is not suitable for the detection of the filling amount of the smoke section of aerosol generating products, such as Figure 1 As shown, the aerosol generating product lies horizontally on the test plate, the light source is located below the test plate and faces the aerosol generating product, and the tester observes from the top of the aerosol generating product whether its smoking section is fully filled with smoking materials. Taking the filling of smoking particles as an example, since the smoking particles are opaque, when the filling amount of smoking particles in the smoking section is more than 50%, the tester cannot see the light of the smoking particles passing through the smoking section of the aerosol generating product. Even when the filling amount is only 25%, the tester can only see a very small amount of light at the edge of the smoking section of the aerosol generating product. If the above method is used to detect the filling amount of the smoke segment in the aerosol generating product, it will directly lead to the following problems: 1. The test result is inaccurate, and only the smoke segment with a filling amount below 50% can be detected. When the filling amount is equal to or greater than 50%, it is fully filled in the eyes of the tester; 2. The detection of the smoke segment with a filling amount below 50% is only a qualitative test, and there is no way to accurately determine the filling amount; 3. The labor intensity of the tester is high and the detection efficiency is low.

[0009] In addition, aerosol generating products have a small diameter, a long length, and a cylindrical shape, which makes them easy to roll when lying flat and easy to slip when standing upright. They need to be manually held, which is labor-intensive and inefficient. Therefore, it is necessary to design a light inspection device suitable for the filling amount of the aerosol generating product smoking section according to the shape of the aerosol generating product and the particularity of the filling smoking material.

[0010] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0011] To solve the above problems, the present invention provides a light inspection device suitable for the filling amount of the smoking section of aerosol generating products, which has low cost, simple operation, high recognition and batch inspection. It can accurately identify whether the aerosol generating source material fills the cavity, which is convenient for product inspection.

[0012] The first aspect of the present invention provides a light inspection method suitable for quantitative analysis of the filling amount of the smoking section of an aerosol generating product, a light inspection device capable of fixing the aerosol generating product, and a surface light source capable of providing a horizontal light beam;

[0013] The line-plane angle between the axis of the aerosol generating product fixed by the light inspection device and the horizontal plane is 0-90°; the axis of the aerosol generating product fixed by the light inspection device is perpendicular to the horizontal light beam provided by the surface light source.

[0014] The angle between a line and a plane refers to the acute angle or right angle formed by a line perpendicular to the plane passing through a point on a straight line that is not parallel to the plane, the line connecting the intersection of this straight line and the plane, and the original straight line.

[0015] The second aspect of the present invention provides a light inspection device suitable for quantitative analysis of the filling amount of the smoking section of an aerosol generating product, which comprises a surface light source 1 and a light inspection box 2;

[0016] The light inspection box 2 comprises a housing 21, a plurality of baffles 22 inside the housing 21, and a plurality of sample holding slots 23 divided by the plurality of baffles 22, wherein the sample holding slots 23 hold aerosol generating products, and the smoke generating section of the aerosol generating products is filled with smoke generating particles or smoke generating paste;

[0017] The surface light source 1 can provide a horizontal light beam and pass through the aerosol generating product contained in the light inspection box 2;

[0018] The line-plane angle between the axis of the aerosol generating product and the horizontal plane is 0-90°; the axis of the aerosol generating product is perpendicular to the horizontal light beam provided by the surface light source 1.

[0019] The light inspection box 2 further includes an outer cover, which is located outside the sample holding tank 23 to prevent the aerosol generating product contained in the sample holding tank 23 from falling. The outer cover is a light-transmitting material selected from transparent glass or transparent plastic to ensure that the aerosol generating product inside the light inspection box 2 can still be observed after the outer cover is closed.

[0020] Preferably, the housing 21 is made of a light-transmitting material selected from transparent glass or transparent plastic to ensure that the light beam can pass through it and reach the aerosol generating product.

[0021] Preferably, the baffle 22 is made of opaque material, selected from brown glass or dark plastic or metal or ceramic, etc., that is, the part of the light inspection box 2 that does not accommodate the aerosol generating product is opaque to prevent the horizontal light beam emitted by the surface light source 1 from irritating the eyes of the inspector.

[0022] Preferably, the size of the sample holding slot 23 matches the size of a single aerosol generating product or matches the size of multiple aerosol generating products arranged side by side to fix the aerosol generating products. In other words, the length, width, and depth of the sample holding slot 23 are mainly to just accommodate the aerosol generating product to be tested, or the length, width, and depth of the sample holding slot 23 are mainly to just accommodate multiple aerosol generating products to be tested arranged in sequence, wherein the baffle 22 forming the sample holding slot 23 is also divided into a baffle arranged horizontally and a baffle arranged vertically.

[0023] Preferably, the surface light source 1 is an LED diffuse panel light, which has uniform width distribution, no flicker, and stable color temperature. The brightness can be adjusted at will through an external regulator, which reduces the fatigue of the inspector and improves the inspection efficiency.

[0024] Preferably, the housing 21 has scales.

[0025] The third aspect of the present invention provides a light inspection method for quantitatively analyzing the filling amount of the smoking section of an aerosol generating product by using the light inspection device, comprising the following steps:

[0026] (1) Load the aerosol generating product to be tested into the sample holding tank 23, and then place the light inspection box 2 in front of the surface light source 1, the line-plane angle between the axis of the aerosol generating product and the horizontal plane is 0-90°, and the axis of the aerosol generating product is perpendicular to the horizontal light beam provided by the surface light source 1;

[0027] (2) turning on the surface light source 1 so that the light beam emitted by the surface light source 1 can pass through the aerosol generating product contained in the light inspection box 2, and calculating the filling amount of the smoking segment according to the ratio of the shadow area of ​​the opaque region in the smoking segment of the aerosol generating product to the shadow area of ​​the smoking segment;

[0028] Filling amount = shadow area of ​​the opaque region in the smoke-generating segment / shadow area of ​​the smoke-generating segment*100%.

[0029] The inspector faces the surface light source and is located in front of the light inspection box. The area in the light inspection box that does not contain the aerosol generating product is opaque to prevent the horizontal light beam emitted by the surface light source 1 from irritating the inspector's eyes. In addition, the filling amount can also be calculated by taking a photo with a camera and then analyzing the photo.

[0030] Preferably, the shell 21 has scales, and different scales match different filling amounts of the smoking segment. The filling amount of the smoking segment is determined by the scales corresponding to the horizontal plane of the opaque area in the smoking segment and the line-plane angle between the axis of the aerosol generating product and the horizontal plane.

[0031] The aerosol generating source described in the present application refers to the smoking particles or smoking paste loaded into the smoking section of the aerosol generating product.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In view of the particularity of the shape of aerosol generating products and the filling of smoking materials, the present invention has designed for the first time a light inspection device suitable for the filling amount of the smoking section of aerosol generating products. The device can accurately identify whether the aerosol generating source fills the cavity and quantitatively determine the filling amount, which is convenient for product inspection and solves the current industry inspection problem of insufficient or empty filling of aerosol generating sources.

[0034] 2. In the light inspection device of the present invention, the light inspection box 2 can be flexibly designed to have a number of inspections according to actual needs. The size of the light inspection box 2 can be customized to achieve batch product inspection. The outer shell 21 and the baffle 22 are detachable for easy operation. In addition, the size of the sample holding tank 23 matches the size of the aerosol generating product or matches the size of a plurality of arranged aerosol generating products to fix the aerosol generating product. In other words, the length, width, and depth of the sample holding tank 23 are mainly to just accommodate the aerosol generating product to be tested, or the length, width, and depth of the sample holding tank 23 are mainly to just accommodate a plurality of sequentially arranged aerosol generating products to be tested. This ensures that no matter whether the light inspection box 2 is placed horizontally or vertically, the aerosol generating products can be neatly placed in the sample holding tank 23, avoiding manual hand-holding of the object to be tested, saving labor, and improving detection efficiency.

[0035] 3. The light inspection device of the present invention perfectly solves the problem that when the existing light inspection device is used for aerosol generating products, when the filling amount is equal to or greater than 50%, it cannot be accurately detected. With the light inspection device of the present invention, no matter how much the filling amount of the smoke section of the aerosol generating product is, it can be accurately detected, the operation is simple, the inspection efficiency is greatly improved, and the light inspection accuracy rate can reach 100%.

[0036] 4. In a preferred embodiment of the present invention, the outer shell 21 of the light inspection box 2 has scales, and different scales match different filling amounts of the smoke-generating segment. The filling amount of the smoke-generating segment is determined by the scale corresponding to the horizontal plane of the opaque area in the smoke-generating segment. Even when the light inspection box 2 is placed at a certain angle to the horizontal direction, the filling amount of the smoke-generating segment is determined by the scale corresponding to the horizontal plane of the opaque area in the smoke-generating segment and the angle. In other words, the light inspection method of the present invention can not only qualitatively identify whether the aerosol generating source material fills the cavity, but more importantly, it can simply and quickly quantitatively determine the filling amount of the aerosol generating source.

[0037] 5. In the light inspection device of the present invention, the baffle 22 is made of opaque material. The baffle 22 can not only block the sample holding groove 23 to fix the aerosol generating product to be tested, but also prevent the horizontal light beam emitted by the surface light source 1 from irritating the eyes of the inspector, thereby reducing the fatigue of the inspector.

[0038] 6. Compared with the current method of evaluating the filling amount of aerosol generating products by weighing, the light inspection device of the present invention has low labor intensity, high accuracy and high efficiency.

[0039] 7. The surface light source 1 in the light inspection device of the present invention is an LED diffuse panel lamp, which has uniform width distribution, no flicker, and stable color temperature. The brightness can be adjusted at will through an external regulator, which reduces the fatigue of the inspector and improves the inspection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
