[0002] In recent years, with the gradual upgrading of consumer demand, adding flavor capsules to cigarette filters can reduce harm and tar, while also further enhancing the richness of cigarette products. Major cigarette manufacturers have launched many products with flavor capsule filters. Flavor capsule filters refer to cigarettes with small liquid beads embedded in the filter. These beads contain liquids of different types of flavorings, which smokers can pop during smoking to release the liquid, thus making the cigarette taste richer and more aromatic.

[0003] Chinese patent application CN201721375561.5 discloses a cigarette filter rod detection device, including an image acquisition unit, a controller, and an application mechanism. The image acquisition unit includes a CCD line array camera, a point light source, and an encoder, used to capture a complete image of the cigarette filter rod containing a flavor capsule. The controller includes a vision algorithm processing platform based on an edge-pair detection tool, used to identify and detect flavor capsule defects in the cigarette filter rod based on the image acquired by the image acquisition unit. The application mechanism includes a display for displaying and storing image information and detection data of the flavor capsule cigarette filter rod. The CCD line array camera, point light source, and encoder are connected to the controller, and the controller is connected to the display. This invention utilizes image acquisition and recognition technology based on vision algorithms to effectively detect flavor capsule defects in cigarette filter rods and accurately remove filter rods with defects in real time, achieving high detection quality and efficiency.

[0004] However, this filter rod detection device requires calibration of the camera lens's mounting position during initial camera installation, or when the camera needs to be reinstalled after disassembly for reasons such as malfunction repair, camera replacement, or cleaning.

[0051] In this embodiment, the beaded filter rod detection device includes:

[0052] Base 1, with a detection port 11 on it, the filter rod 100 is along the first direction (e.g. Figure 1 (As shown in the x-direction) extends and passes through detection port 11;

[0054] The second fixing frame 3 is movably mounted on the first fixing frame 2, and the second fixing frame 3 is movable relative to the first fixing frame 2 in a third direction (e.g., Figure 1 Sliding in the z-direction (as shown in the middle), the third direction is perpendicular to the first and second directions respectively;

[0059] The second drive mechanism 7 is mounted on the second fixed frame 3. The drive end of the second drive mechanism 7 is connected to the mounting block 4 and is used to drive the mounting block 4 to move along the first direction.

[0060] By adopting the above technical solution, the first fixed frame 2 is slidably mounted on the base 1, allowing it to move along the second direction on the base 1, and the position of the first fixed frame 2 is locked using the locking member 8. A first drive mechanism 6 is provided on the first fixed frame 2, with its drive end connected to the second fixed frame 3, allowing the operator to move the second fixed frame 3 along a third direction using the first drive mechanism 6. A second drive mechanism 7 is provided on the second fixed frame 3, with its drive end connected to the mounting block 4 equipped with the image acquisition unit 5, allowing the operator to move the mounting block 4 and the image acquisition unit 5 along the first direction using the second drive mechanism 7.

[0061] This embodiment moves the mounting block 4 in three directions mechanically, that is, the image acquisition unit 5 can be moved in three directions, and the position of the image acquisition unit 5 can be finely adjusted in the first direction and the third direction, thereby enabling rapid calibration of the position of the image acquisition unit 5.

[0062] In this embodiment, refer to Figure 1 The base 1 is rectangular in shape, and its upper surface is a platform. A detection port 11 is provided on one side of the base 1, and an image acquisition unit 5 is positioned above the detection port 11 to acquire images of the filter rod 100 to be inspected at the detection port 11. The filter rod 100 extends along a first direction and is disposed on one side of the base 1 with the detection port 11, and can move along the first direction to detect different positions of the filter rod 100 to be inspected.

[0063] Furthermore, a light source 9 is provided below the detection port 11. The light source 9 is positioned below the image acquisition unit 5, and its main function is to project light onto the filter rod 100 to be tested in a suitable manner. This technical solution facilitates the acquisition of a clear image of the filter rod 100.

[0064] For example, the image acquisition unit 5 is a CCD camera.

[0065] Furthermore, a guide tube 12 extending in the first direction is provided at the detection port 11.

[0066] By adopting the above technical solution, the filter rod 100 can be prevented from shaking during travel, thereby improving the detection accuracy; in addition, it can prevent dust or adhesive residues that fall off the filter rod 100 from contaminating the camera lens.

[0067] Specifically, brackets 121 are provided at both ends of the detection port 11 to support the guide tube 12. The upper end of the bracket 121 is arc-shaped to fit against the outer wall of the guide tube 12; the bracket 121 is fixed to the side wall of the detection port 11 by screws.

[0068] For example, the delivery tube 12 is a transparent glass tube.

[0069] Using the above technical solution, the light emitted by the light source 9 can pass through the transparent glass tube and illuminate the filter rod 100 to be tested.

[0070] Furthermore, the base 1 is provided with two slide rails 13 extending along the second direction, and the two slide rails 13 are spaced apart along the first direction.

[0071] The first fixing frame 2 includes a first side plate 21, a second side plate 22 and a top plate 23. The first side plate 21 and the second side plate 22 are spaced apart along a first direction. The top plate 23 spans between the first side plate 21 and the second side plate 22 along the first direction, and the two ends of the top plate 23 are respectively connected to the first side plate 21 and the second side plate 22. The bottom of the first side plate 21 and the second side plate 22 are respectively provided with a first sliding groove 211, and the two first sliding grooves 211 are respectively slidably connected to two slide rails 13.

[0072] Using the above technical solution, the first fixed frame 2 can move along the slide rail 13 in the second direction.

[0073] Specifically, two slide rails 13 are disposed on the upper surface of the base 1, extending along a second direction and spaced a certain distance apart in the first direction. The first fixing frame 2 includes a first side plate 21, a second side plate 22, and a top plate 23. The first side plate 21 and the second side plate 22 are vertically disposed on the base 1, and the first sliding grooves 211 at the bottom of the first side plate 21 and the second side plate 22 extend along the second direction and are slidably connected to the two slide rails 13 respectively. When the first side plate 21 and the second side plate 22 move along the slide rails 13 in the second direction, they drive the entire first fixing frame 2 to move in the second direction. The top of the first side plate 21 and the second side plate 22 is connected to the top of the top plate 23, which is used to connect and fix the first side plate 21 and the second side plate 22.

[0074] For example, the first slide groove 211 has a first threaded hole 212 on its side wall, and the locking member 8 is a screw. The screw is threaded into the first threaded hole 212, and the end of the screw can abut against the slide rail 13.

[0075] Using the above technical solution, the first fixing bracket 2 can be detachably fixed to the slide rail 13. Multiple threaded holes 212 are arranged side-by-side along the second direction, and the first threaded holes 212 are located on the outer sidewall of the first slide groove 211. In use, by loosening the screws, the first fixing bracket 2 can be moved towards the detection port 11, allowing the image acquisition unit 5 to be replaced at a position away from the detection port 11. After moving the first fixing bracket 2 towards the detection port 11 and positioning the image acquisition unit 5 above the detection port 11, the first fixing bracket 2 is then fixed to the slide rail 13 using screws.

[0076] It should be noted that this utility model does not limit the number of the first threaded hole 212 and the screw, as long as it can fix the first fixing bracket 2.

[0077] Furthermore, referring to Figure 2 The first side plate 21 and the second side plate 22 are each provided with a second sliding groove 213 extending in a third direction, and the second sliding groove 213 on the first side plate 21 and the second sliding groove on the second side plate 22 are arranged opposite to each other.

[0079] The third side plate 31 is perpendicular to the second direction, and the two edges of the third side plate 31 extending along the first direction are respectively inserted into the two second sliding grooves 213.

[0080] The fourth side plate 32 and the fifth side plate 33 are spaced apart along the first direction. The fourth side plate 32 and the fifth side plate 33 are located on the same side of the third side plate 31, and the ends of the fourth side plate 32 and the fifth side plate 33 are connected to the third side plate 31.

[0081] Using the above technical solution, the second fixed frame 3 can move upward along the second slide groove 213 in the third direction.

[0082] Specifically, a second sliding groove 213 is provided on the opposite side surface of the first side plate 21 and the second side plate 22, and the second sliding groove 213 extends in a third direction.

[0083] The second mounting bracket 3 includes a third side plate 31, a fourth side plate 32, and a fifth side plate 33. The third side plate 31 extends along a first direction and is disposed perpendicular to the upper surface of the base 1 between the first side plate 21 and the second side plate 22. The two edges of the third side plate 31 are respectively inserted into the second sliding grooves 213 of the two side plates, thereby allowing the third side plate 31 to slide slidably connect with the first side plate 21 and the second side plate 22. The fourth side plate 32 and the fifth side plate 33 extend along a second direction, and one end of each side plate is fixedly connected to the inner side of the two edges of the third side plate 31. The mounting block 4 and the image acquisition unit 5 are disposed within the space enclosed by the third side plate 31, the fourth side plate 32, and the fifth side plate 33.

[0084] Furthermore, the first fixing frame 2 also includes a connecting plate 24, which is located below the top plate 23 and spaced a certain distance from the top plate 23. The connecting plate 24 extends along the first direction, and its two ends are connected to the first side plate 21 and the second side plate 22, respectively.

[0085] The first drive mechanism 6 includes a first lead screw 61, which extends along a third direction. The two ends of the first lead screw 61 are rotatably connected to the top plate 23 and the connecting plate 24, respectively. The third side plate 31 is provided with a second threaded hole 311 that passes through the third side plate 31 along a third direction. The first lead screw 61 passes through the second threaded hole 311 and is threadedly connected to the second threaded hole 311.

[0086] By adopting the above technical solution, the first lead screw 61 is rotated to drive the third side plate 31 to move in the third direction, thereby adjusting the position of the second fixing frame 3 in the third direction.

[0087] Specifically, the first fixing frame 2 also includes a connecting plate 24, which is disposed opposite to the top plate 23 and below the top plate 23 and close to the base 1. The connecting plate 24 is connected between the first side plate 21 and the second side plate 22. The first lead screw 61 is vertically disposed between the top plate 23 and the connecting plate 24, and its two ends are rotatably connected to the top plate 23 and the connecting plate 24, respectively. The third side plate 31 has a second threaded hole 311 in the third direction at its middle position. The first lead screw 61 is inserted through the second threaded hole 311, thereby threading the third side plate 31 and the first lead screw 61 together. When the first lead screw 61 is rotated, the third side plate 31 can move along the second slide groove 213, thereby adjusting the position of the third side plate 31 in the third direction, and thus adjusting the position of the image acquisition unit 5 in the third direction.

[0088] It should be noted that the connection method between the first lead screw 61 and the top plate 23 and the connecting plate 24 is not limited in this utility model, as long as the first lead screw 61 can rotate relative to the top plate 23 and the connecting plate 24. Optionally, the top plate 23 and the connecting plate 24 are respectively provided with sleeves with internal threads at the positions where they connect with the first lead screw 61. The sleeves are fixed to the top plate 23 and the connecting plate 24. When the first lead screw 61 rotates to the predetermined position, the position of the third side plate 31 on the first lead screw 61 is fixed by inserting a stop screw into the sleeve, thereby fixing the position of the image acquisition unit 5 in the third direction.

[0089] Furthermore, referring to Figure 2 and Figure 3 The fourth side plate 32 and the fifth side plate 33 are both provided with guide holes 34; the mounting block 4 includes a block body 41 and two guide rods 42. The two guide rods 42 are located on both sides of the block body 41 along the first direction, and the two guide rods 42 pass through the two guide holes 34 respectively along the first direction.

[0090] Using the above technical solution, the guide holes 34 on the fourth side plate 32 and the fifth side plate 33 are arranged opposite to each other and the line connecting the two guide holes 34 is located in the first direction. The two guide rods 42 located on both sides of the block body 41 of the mounting block 4 are respectively inserted through the guide holes 34 on the fourth side plate 32 and the fifth side plate 33 to provide guidance for the movement of the mounting block 4 in the first direction.

[0091] Furthermore, referring to Figure 2 The second drive mechanism 7 includes a second lead screw 71, which extends along a first direction and its two ends are rotatably connected to the fourth side plate 32 and the fifth side plate 33, respectively. The mounting block 4 is provided with a third threaded hole 411 that passes through the block body 41 of the mounting block 4 along the first direction. The second lead screw 71 passes through the third threaded hole 411 and is threadedly connected to the third threaded hole 411.

[0092] By adopting the above technical solution, by rotating the second lead screw 71, the mounting block 4 is moved in the first direction, thereby adjusting the position of the mounting block 4 in the first direction, and thus adjusting the position of the image acquisition unit 5 in the first direction.

[0093] Specifically, the second lead screw 71 is disposed between the fourth side plate 32 and the fifth side plate 33 along the first direction, and both ends of the second lead screw 71 are rotatably connected to the fourth side plate 32 and the fifth side plate 33, respectively. The block body 41 of the mounting block 4 is provided with a third threaded hole 411 extending along the first direction. The second lead screw 71 is inserted through the third threaded hole 411, thereby threading the mounting block 4 with the second lead screw 71. When the second lead screw 71 is rotated, the mounting block 4 can move along the guide hole 34, thereby adjusting the position of the mounting block 4 in the first direction, and consequently adjusting the position of the image acquisition unit 5 in the first direction.

[0094] It should be noted that the connection method between the second lead screw 71 and the fourth side plate 32 and the fifth side plate 33 is not limited in this utility model, as long as the second lead screw 71 can rotate relative to the fourth side plate 32 and the fifth side plate 33. Optionally, the fourth side plate 32 and the fifth side plate 33 are respectively provided with sleeves with internal threads at the connection positions with the second lead screw 71. The sleeves are fixed to the fourth side plate 32 and the fifth side plate 33. When the second lead screw 71 rotates to the predetermined position, the second lead screw 71 is fixed by inserting a stop screw into the sleeve, thereby fixing the mounting block 4 in the third-party upward position.

[0095] For example, in one embodiment of this implementation, a servo motor is connected to the end of the first lead screw 61 and / or the second lead screw 71. In this embodiment, the servo motor drives the first lead screw 61 and / or the second lead screw 71 to rotate, so as to fine-tune the position of the image acquisition unit 5.

[0096] In another embodiment of this implementation, as exemplified, reference is made to... Figure 1 and Figure 2 The ends of the first lead screw 61 and / or the second lead screw 71 are respectively provided with a first handle 62 and a second handle 72. The first handle 62 and the second handle 72 are provided with pointers. The outer side of the fifth side plate 33 and / or the top plate 23 is provided with a scale, and the pointer is used to indicate the scale on the corresponding scale.

[0097] In this embodiment, the position of the image acquisition unit 5 is finely adjusted by rotating the handle to rotate the first lead screw 61 and / or the second lead screw 71. A first handle 62 can be provided at the end of the first lead screw 61, and a scale can be provided on the top plate 23. Alternatively, a second handle 72 can be provided at the end of the second lead screw 71, and a scale can be provided on the fifth side plate 33. Alternatively, both the first and second handles 62 can be provided at the end of the first and second lead screws 61, and scales can be provided on both the top plate 23 and the fifth side plate 33.

[0098] For example, the pitch of the first lead screw 61 and / or the second lead screw 71 is divided into 10 parts, which correspond to one circumference of a dial. That is, there are 10 graduations on one circumference of the dial, and each graduation is 1 / 10 of the pitch. In other words, each rotation of one graduation moves the image acquisition unit 5 by 1 / 10 of the pitch in the first direction or a third direction. For example, if the pitch of the second lead screw 71 is 1mm, then each graduation on the dial is 0.1mm. Each rotation of the handle moves the image acquisition unit 5 by 0.1mm in the first direction, thus allowing for precise adjustment of the position of the image acquisition unit 5.

[0099] Furthermore, referring to Figure 1 The base 1 is provided with two grooves 14 extending along the first direction. The two grooves 14 are respectively located on both sides of the detection port 11 along the first direction. The grooves 14 are used to place the filter rod 100.

[0100] The above technical solution provides guidance for the movement of the filter rod 100.

[0101] The capsule filter rod detection device provided by this utility model can adjust the position of the image acquisition unit in three directions and can fine-tune the position of the image acquisition unit in the first and third directions, thereby enabling rapid calibration of the image acquisition unit's position. Research has shown that before using this capsule filter rod detection device, calibrating the image acquisition unit took 10 minutes, while after using this device, the calibration time is reduced to 2 minutes, significantly shortening the calibration time required.
