[0062] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0063] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0064] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0065] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] As shown in the figure, the clamping assembly of the cigarette detection device of this embodiment includes a clamping seat 4 and a clamping member 5 installed on the clamping seat 4. The clamping seat 4 includes a plurality of guide holes 43 extending in the radial direction of the clamping seat. The clamping member includes a plurality of clamping blocks 51. The clamping blocks include a moving portion extending into the clamping seat and matching with the guide holes one by one and a clamping portion extending out of the clamping seat for clamping cigarettes. The guide holes 43 extend in the radial direction of the clamping seat 4. In the embodiment shown in the figure, the guide holes 43 penetrate the clamping seat 4 in the radial direction. In some embodiments not shown in the figure, the guide holes 43 may not penetrate the clamping seat 4, but only extend in the radial direction of the clamping seat 4 to the middle of the wall of the clamping seat 4 and then no longer extend. The moving portion 511 of each clamping block 51 matches with a guide hole 43 and can move relative to the guide hole 43 in the radial direction of the clamping seat. As shown in the figure, the plurality of clamping blocks are distributed in the circumferential direction to form a circle. A clamping cavity is formed between the plurality of clamping blocks, and the clamping cavity is located in the radial inner side of the plurality of clamping blocks. The clamping member has a cigarette loading state in which the clamping cavity is opened to load cigarettes and a cigarette clamping state in which the clamping cavity is reduced to clamp the cigarettes. The clamping assembly also includes an elastic member that cooperates with the moving parts of the multiple clamping blocks. The elastic force of the elastic member causes the moving parts of the multiple clamping blocks to tend to move toward the radial inner side of the clamping seat.

[0068] The clamping assembly of the cigarette detection device of this embodiment can fully and reliably clamp cigarettes by providing a clamping member including a plurality of clamping blocks and making the clamping blocks enclose a clamping cavity. At the same time, by providing a clamping block including a moving part and a clamping part and providing a guide hole extending radially along the clamping seat in cooperation with the moving part to guide the movement of the moving part, when the clamping block is pushed to move radially outward in the guide hole, the clamping member can be stably and reliably switched to the cigarette loading state. After the external force pushing the clamping block radially outward is cancelled, the provision of the elastic member can enable the clamping member to switch to the cigarette clamping state in time and reliably clamp the cigarette. The state switching of the clamping member is stable and orderly, and the clamping force for clamping the cigarette is uniform and reliable.

[0069] In some embodiments, the clamping seat 4 includes a second cylinder 451 and an annular disk 452 located on the end surface of the cylinder, and the guide hole 43 includes a strip-shaped through hole provided on the second cylinder 451, that is, a strip-shaped through hole that penetrates the second cylinder 451 along the radial direction of the clamping seat. The moving part 511 is inserted into the strip-shaped through hole, and the clamping part 512 extends out of the clamping seat 4 from the through hole in the middle of the annular disk. The moving part 511 and the clamping part 512 are connected by a step surface. In the embodiment shown in the figure, the step surface extends into the guide hole 43, and the guide hole 43 guides the movement of the moving part in the guide hole by contacting with the step surface, so that the clamping seat can stably switch between the cigarette loading state and the cigarette clamping state.

[0070] In some embodiments, as shown in the figure, the guide hole 43 radially penetrates the clamping seat 4, and the moving part of the clamping block is also provided with a first mounting groove 513, and the clamping seat is provided with an annular second mounting groove 44. After the clamping block is installed on the clamping seat, the annular elastic ring is installed on the second mounting groove and the first mounting groove 513 at the same time, and the elastic force of the elastic ring points to the radial inner side of the elastic ring. After the cigarette is loaded into the clamping cavity, after the push rod leaves the clamping block, the elastic force of the elastic ring causes the clamping block to move toward the radial inner side of the clamping seat, so that the clamping block clamps the cigarette. When the push rod moves in the direction close to the clamping block, the push rod pushes the clamping block to overcome the elastic force of the elastic ring, so that the clamping block moves toward the radial outer side of the clamping seat, and the clamping member switches to the cigarette loading state.

[0071] As shown in the figure, the cigarette detection device of this embodiment includes a transmission cylinder 3, a driving assembly, a pushing assembly, a clamping assembly, a matching piece 2 and a fixing piece 17.

[0072] The transmission cylinder 3 includes a first cylinder body 31 , a cylinder cavity 32 disposed inside the first cylinder body 31 , a first transmission portion 33 disposed on the first cylinder body 31 , and a first connecting portion 34 disposed at one end of the first cylinder body 31 .

[0073] The driving assembly is connected to the transmission cylinder 3, and the driving assembly is used to drive the transmission cylinder 3 to rotate. In the embodiment shown in the figure, the driving assembly includes a motor 11, a first transmission wheel 12, a second transmission wheel 14, and a belt connecting the first transmission wheel 12 and the second transmission wheel 14. The motor is mounted on the mounting seat 7, the motor drives the first transmission wheel 12 to rotate, the belt transmits power to the second transmission wheel 14, and the second transmission wheel 14 drives the transmission cylinder 3 to rotate. In the embodiment shown in the figure, a keyway is provided on the transmission cylinder, and a transmission key that cooperates with the keyway on the transmission cylinder 3 is provided on the second transmission wheel, and the second transmission wheel drives the transmission cylinder to rotate through the cooperation of the transmission key and the keyway.

[0074] The push assembly includes a second transmission part, a push rod 6 disposed in the barrel cavity 32, a third transmission part 63 disposed on the push rod 6, and a first threaded part 61 disposed on the push rod 6, the axis of the thread being parallel to the axis of the transmission barrel. The first transmission part 33 and the second transmission part slide and cooperate along the axial direction of the transmission barrel, and when the transmission barrel 3 rotates, the push rod 6 is driven to rotate coaxially with the transmission barrel 3 through the cooperation of the first transmission part 33 and the second transmission part. The first transmission part 33 and the second transmission part can transmit torque and slide relative to each other. In some embodiments, one of the first transmission part and the second transmission part includes a slide groove, and the other includes a sliding block that cooperates with the slide groove. In the embodiment shown in the figure, the first transmission part includes a slide groove extending axially of the first barrel 31, and the second transmission part includes an annular ring 91, a sliding column 92 fixedly connected to the annular ring 91, and a connecting hole fixedly connected to the sliding column 92 disposed on the push rod 6. In the embodiment shown in the figure, it includes a plurality of sliding posts 92 that slide along the circumferential direction of the push rod and a plurality of connecting holes that are arranged on the push rod and are distributed along the circumferential direction. One connecting hole is fixedly connected to one sliding post 92 by means of threaded connection or the like. During operation, the transmission cylinder transmits the torque to the sliding post through the slide groove, and the sliding post transmits the torque to the connecting hole on the push rod to rotate the push rod. At the same time, the sliding post can move along the axial direction of the transmission cylinder relative to the slide groove.

[0075] The clamping seat 4 of the clamping assembly includes a second connecting portion 41 detachably connected to the first connecting portion 34 and a fourth transmission portion 42 arranged on the clamping seat 4, the third transmission portion 63 and the fourth transmission portion 42 slide and cooperate along the axial direction of the transmission cylinder, and when the push rod 6 rotates, the clamping seat 4 is driven to rotate coaxially with the push rod 6 through the cooperation of the third transmission portion 63 and the fourth transmission portion 42. The cooperation of the third transmission portion 63 and the fourth transmission portion 42 is similar to the cooperation of the first transmission portion and the second transmission portion, one of which includes a slide groove, and the other includes a sliding block that cooperates with the slide groove. In the embodiment shown in the figure, the third transmission portion includes a slide groove arranged on the push rod, the fourth transmission portion 42 includes a transmission hole arranged on the clamping seat 4 and a transmission pin inserted into the transmission hole and inserted into the slide groove of the fourth transmission portion, the transmission pin can slide and cooperate relative to the slide groove of the fourth transmission portion, and the fourth transmission portion transmits torque to the transmission hole through the cooperation of the slide groove and the transmission pin, and then drives the clamping seat 4 to rotate. In this embodiment, the clamping seat 45 is detachably connected to the first connecting portion 34 through the second connecting portion 41, so that the clamping seat 45 can be conveniently installed on the transmission cylinder and the clamping member can be conveniently installed or separated from the clamping seat 45 after the clamping seat 45 is removed. After the clamping seat is installed on the transmission cylinder, since the push rod can reliably transmit torque to the clamping seat 45, the connection between the clamping seat 45 and the transmission cylinder no longer needs to have the requirement of reliable torque transmission, so the detachable connection between the clamping seat 45 and the transmission cylinder can be set as a simple threaded connection, which reduces the connection requirements, and the clamping seat 45 and the transmission cylinder can be conveniently and simply disassembled.

[0076] The push rod 6 drives the clamping member 5 to switch between the cigarette loading state and the cigarette clamping state by moving in the positive direction and the reverse direction along the axial direction of the transmission cylinder 3. The movement of the push rod 6 in one direction along the axial direction is the positive direction movement, and the movement in the reverse direction along the axial direction is the reverse direction movement opposite to the positive direction. In the embodiment shown in the figure, the movement of the push rod toward the clamped cigarette is the positive direction movement, and the movement away from the cigarette is the reverse direction movement. The push rod moves in the positive direction to drive the clamping cavity of the clamping member 5 to open, so that cigarettes can be loaded or removed. The push rod moves in the reverse direction, which can drive the clamping cavity of the clamping member 5 to become smaller, so that the loaded cigarettes can be clamped.

[0077] The fitting member 2 is rotatably disposed in the cylinder cavity 32 relative to the transmission cylinder 3 and includes a second threaded portion 21 threadably matched with the first threaded portion 61. The fixing member 17 is used to match with the fitting member 2, and the fixing member 17 has a first state that limits the fitting member 2 from rotating around the axis of the thread of the first threaded portion 61 and a second state that allows the fitting member 2 to rotate around the axis of the thread of the first threaded portion 61. In the embodiment shown in the figure, the fixing member includes an electromagnetic clutch 17, and the electromagnetic clutch includes a first part and a second part that are relatively rotatable. The first part is mounted on the mounting seat 7 through the mounting frame 16 and the mounting block 15, and the second part is fixedly connected to the fitting member 2. The fixing member 17 can be switched between the first state and the second state by connecting and separating the first part and the second part.

[0078] When the fixing member 17 is switched to the first state, the mating member 2 is restricted from rotating, and when the push rod 6 is driven to rotate by the transmission cylinder, the push rod can produce a motion effect similar to that of a screw-nut mechanism through the threaded cooperation between the first threaded portion 61 and the second threaded portion of the mating member 2, so that the push rod moves along its axial direction. When the driving assembly drives the transmission cylinder to rotate in different directions, the driving cylinder also drives the push rod to rotate in different directions, and the push rod will move in the positive direction or the reverse direction under the action of the second threaded portion of the mating member 2 that is restricted from rotating, thereby driving the clamping member to switch between the cigarette loading state and the cigarette clamping state. When the fixing member 17 is switched to the second state, the matching member 2 is not restricted from rotating, and the matching member 2 can rotate around the axis of the thread of the first threaded portion 61, that is, it can rotate relative to the transmission cylinder, so that when the push rod 6 is driven to rotate by the transmission cylinder, the matching member 2 can rotate with the push rod, the push rod does not move, and the push rod drives the clamping seat, the clamping member and the cigarette to rotate, so that the outer peripheral surface of the cigarette can be fully detected by the detection component of the cigarette detection device, such as the camera detection device 18 shown in the figure.

[0079] The cigarette detection device of this embodiment can switch the clamping member 5 between the cigarette loading state and the cigarette clamping state by switching the fixing member 17 between the first state and the second state, and by driving the transmission cylinder to rotate in different directions, so that the operation of loading cigarettes 100 and clamping cigarettes 100 can be conveniently performed, and the cigarette can be automatically rotated after being clamped so that different parts of the cigarette can be conveniently detected by the detection component. At the same time, the clamping seat 4 can be conveniently detachably connected to the transmission cylinder 3, so that the installation and removal of the clamping member 5 can be convenient. After the clamping seat 4 is connected to the transmission cylinder 3, the clamping seat 4 can reliably drive the clamping member 5 and the cigarette to rotate coaxially with the transmission cylinder 3.

[0080] In some embodiments, the cigarette detection device further includes a limiting assembly for limiting the movement of the matching member 2 relative to the transmission cylinder along the axial direction of the transmission cylinder 3. In the embodiment shown in the figure, the limiting assembly includes a first annular groove 22 with a U-shaped groove cross-section on the matching member 2, an annular retaining ring 23 installed on the first annular groove 22, and a second annular groove 35 with a U-shaped groove cross-section at one end of the transmission cylinder 3, and the annular retaining ring 23 is simultaneously inserted into the groove body of the second annular groove 35. The second annular groove 35 is formed by the end groove 351 of the transmission cylinder 3 and the washer 352 installed at the end of the transmission cylinder 3. When the cigarette to be clamped rotates so that all parts of its outer circumference are fully detected by the detection component, the fixing member 17 switches to the second state, the matching member 2 is not restricted from rotating, the matching member 2 can rotate relative to the transmission cylinder, the push rod 6 is driven to rotate by the transmission cylinder, and the matching member 2 rotates with the push rod. If the matching member is not restricted from moving by the restriction component, the matching member 2 and the push rod may move axially, which may affect the clamping member, for example, switching the clamping member to the cigarette loading state, causing the cigarette to loosen. In this embodiment, the restriction component is set to restrict the matching member 2 from moving relative to the transmission cylinder along the axial direction of the transmission cylinder 3, which can limit the axial movement of the matching member and the push rod when the cigarette is rotated and detected, and avoid the push rod and the matching member from interfering with the clamping member.

[0081] In some embodiments, the first connection portion 34 and the second connection portion 41 are detachably connected by threaded engagement.

[0082] In some embodiments, as shown in the figure, at least one of the surfaces of the push rod 6 and the moving part 511 and the moving part 511 and the push rod is a wedge-shaped surface. In the embodiment shown in the figure, both the surface of the push rod 6 and the surface of the moving part 511 are wedge-shaped surfaces at the matching position. As shown in the figure, the end of the push rod is a tapered portion, and the outer surface of the tapered portion is an inclined surface. The movement of the push rod can reliably push the moving part 511 to move radially along the clamping seat through the action of the wedge-shaped surface.

[0083] In some embodiments, as shown in the figure, the cigarette detection device further includes a controller and a bearing seat assembly, the bearing seat assembly includes a bearing seat 8 and a bearing disposed in the bearing seat, and the transmission cylinder 3 is installed in the bearing seat through the bearing. In the embodiment shown in the figure, it includes a first bearing 93 and a second bearing 94, the bearing seat is provided with a first bearing cavity 831 and a second bearing cavity 832, the first bearing 93 and the second bearing 94 are respectively installed in the first bearing cavity 831 and the second bearing cavity 832, and the two ends of the transmission cylinder 3 are installed on the bearing seat through the first bearing 93 and the second bearing 94. A position detection sensor connected to the controller signal is also provided on the bearing seat, and the position detection sensor is used to detect the position of the push rod 6. In this embodiment, by providing a detection sensor, it is possible to detect the axial position of the push rod 6 along the transmission cylinder, so that it can be determined whether the push rod plays a pushing role on the clamping member at this time, and the state of the clamping member can be determined. In some embodiments, the size of the clamping cavity of the clamping member can be adjusted by detecting and controlling the axial position of the push rod 6 to control the size of the clamping force for clamping the cigarette.

[0084] In some embodiments, the first transmission part 33 includes a strip hole provided on the first cylinder 31, the second transmission part includes an annular ring 91 provided around the transmission cylinder 3 and a sliding column 92 that slides with the strip hole and is fixedly connected to the push rod 6 and the annular ring, and the position detection sensor is used to detect the position of the annular ring 91. In the embodiment shown in the figure, a screw hole is provided on the sliding column 92, and a countersunk hole is provided on the annular ring. The annular ring and the sliding column 92 can be connected by screws passing through the countersunk hole of the annular ring and threadedly matching the screw hole of the sliding column 92. Since the annular ring 91 is fixedly connected to the push rod through the sliding block, the axial position of the annular ring can be detected, that is, the axial position of the push rod can be reflected.

[0085] In some embodiments, the bearing seat includes a mounting hole 82 located radially outside the annular ring 91, and the position detection sensor includes a first photoelectric detection switch 811 and a second photoelectric detection switch 812 disposed in the mounting hole 82. Along the axial direction of the transmission cylinder 3, the annular ring 91 is located between the first photoelectric detection switch 811 and the second photoelectric detection switch 812. The first photoelectric detection switch 811 and the second photoelectric detection switch 812 can be axially arranged at corresponding positions of the axial limit position of the push rod. When the push rod moves in the positive direction or in the reverse direction along the axial direction and is detected by the first photoelectric detection switch 811 or the second photoelectric detection switch 812, it means that the push rod has reached the limited movement position along the axial direction, so that the controller can stop the rotation of the transmission cylinder and stop the push rod from moving. The positions of the first photoelectric detection switch 811 and the second photoelectric detection switch 812 along the axial direction of the transmission cylinder can be adjusted, so that the limited movement position of the push rod along the axial direction can be adjusted.

[0086] In some embodiments, as shown in the figure, the cigarette detection device further includes a dust cover 95, which is threadedly engaged with the bearing seat and surrounds the clamping assembly. The dust cover 95 surrounds the clamping assembly, which can protect the cigarette detection device from dust intrusion, and helps to ensure the long-term and reliable operation of the cigarette detection device.

[0087] In some embodiments, the controller described above may be a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any appropriate combination thereof, for performing the functions described in the present invention.
