Description

Technical Field

[0001] This utility model relates to the field of filter rod detection technology, and in particular to an imaging detection device. Background Technology

[0002] In the production of flavored filter rods, flavored beads are inserted into long filter rods at fixed intervals. These long filter rods are then cut into filter rods of a certain length. Before cutting, an imaging detection device is used to inspect the state of the flavored beads within the long filter rods without affecting normal production. As the long filter rods pass through the inspection channel of the imaging detection device, the adhesive on them easily detaches and adheres to the lower surface of the lens. Furthermore, since most filter rod production processes take place below the imaging detection device, soot and other contaminants generated during production float upwards and adhere to the lower surface of the lens, resulting in a large accumulation of dust and lens contamination. Failure to clean this promptly will reduce the accuracy of the filter rod imaging detection, thus affecting the quality of the cigarette production. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the embodiment of this utility model provides an imaging detection device, including: a bracket 1, an imaging device 2, a detection block 3, a lens 4, a scraping brush 5, a driving mechanism 6, and a cleaning device 7.

[0043] Specifically, the imaging device 2 is mounted on the bracket 1, and the detection end of the imaging device 2 is located below the imaging device 2.

[0044] The detection block 3 is located below the detection imager 2, and the detection block 3 has a vertically oriented (e.g., Figure 1 , Figure 2 , Figure 8 and Figure 9 The first through hole 31 (shown in the Z direction) penetrates the detection block 3. The first through hole 31 is located within the detection area of ​​the imaging instrument 2. The detection block 3 also has a detection channel 32 that allows the filter rod 8 to pass through. The detection channel 32 is along the first direction (e.g., the Z direction). Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the X-direction extends and the first through-hole 31 is connected to the detection channel 32. For example, the X-direction can be horizontal.

[0045] Lens 4 is positioned between the image detector 2 and the detection block 3.

[0046] The squeegee 5 extends along the X direction and is located below the lens 4, with its top contacting the lower surface of the lens 4. For example, the squeegee 5 is made of rubber, and its upper surface is serrated.

[0047] The drive mechanism 6 is connected to the scraper brush 5, and the drive mechanism 6 is used to drive the scraper brush 5 along the second direction (e.g., Figure 1 , Figure 2 , Figure 5 and Figure 6 The squeegee 5 moves back and forth in the Y direction (as shown), with the Y direction perpendicular to the X direction. When the squeegee 5 moves, its upper surface can scrape off the adhesive residue remaining under the lens 4.

[0048] A blower 7 is disposed on one side of the lens 4. The blower 7 has an air outlet 71 for blowing air toward the lower surface of the lens 4. For example, the air outlet 71 is at a 45° angle to the lower surface of the lens 4. When the blower 7 blows air, it can blow away dust and some adhesive residue from the lower surface of the lens 4.

[0049] Optionally, an imaging detection device further includes a control system (not shown in the figure), which is electrically connected to the motor 64 and the solenoid valve. The control system is used to control the movement of the scraper brush 5 and to control the switching of the cleaning blower 7. Exemplarily, the control system is a PLC programmable controller.

[0050] This application, by incorporating a cleaning device 7, enables the removal of some adhesive residue and dust from the lower surface of the lens 4. By incorporating a scraping brush 5 and using a drive mechanism 6 to move the scraping brush 5, the scraping brush 5 can scrape the lower surface of the lens 4 to remove residual adhesive residue. The cleaning device 7 then blows away the adhesive residue scraped off by the scraping brush 5, thus cleaning away all dust and adhesive residue from the lower surface of the lens 4. This achieves automatic cleaning of the lens 4 in the filter rod imaging detection device, thereby improving detection accuracy.

[0051] In some implementations, reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The drive mechanism 6 includes a support 61, a guide rod 62, a lead screw 63, and a motor 64.

[0052] The support 61 is located between the detection image instrument 2 and the detection block 3. The support 61 is located outside the detection area of ​​the detection image instrument 2, and the support 61 and the cleaning device 7 are located on both sides of the detection area of ​​the detection image instrument 2 along the Y direction.

[0053] The end of the guide rod 62 is connected to the support 61. The guide rod 62 extends along the Y direction and is located outside the detection area of ​​the imaging instrument 2. The scraper brush 5 is provided with a second through hole 51 that extends through the scraper brush 5 along the Y direction. The second through hole 51 is sleeved on the outside of the guide rod 62, and the scraper brush 5 can slide along the guide rod 62.

[0054] The end of the lead screw 63 is rotatably connected to the support 61. The scraper brush 5 is provided with a threaded hole 52 that passes through the scraper brush 5 in the Y direction. The lead screw 63 is inserted into the threaded hole 52 and threadedly connected to the threaded hole 52.

[0055] Motor 64 is connected to lead screw 63 and is used to drive lead screw 63 to rotate around its axis. When lead screw 63 rotates, scraper brush 5 can move in the Y direction.

[0056] It should be noted that when the imaging device 2 is inspecting the filter rod 8, the scraper brush 5 cannot clean the lens 4, as its movement along the Y direction would interfere with the normal inspection of the imaging device 2. Therefore, when the imaging device 2 is operating normally, the scraper brush 5 remains outside the inspection area of ​​the imaging device 2. When the scraper brush 5 is cleaning the lens 4, the control system will pause the operation of the imaging device 2. Once the scraper brush 5 stops cleaning, the imaging device 2 will restart to inspect the filter rod 8.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the end of the cleaner 7 furthest from the air outlet 71 is equipped with an air pipe 72, which is connected to an air source. An electromagnetic valve (not shown) is installed on the air pipe 72 to control the opening or closing of the air pipe 72. Exemplarily, a throttle valve (not shown) can also be installed on the air pipe 72 to adjust the air pressure of the gas ejected by the cleaner 7, thereby cleaning the lens 4 more effectively. Exemplarily, the air source is provided by an air pump, air cylinder, or air station.

[0058] Specifically, after the filter rod production unit is powered on, the produced filter rod 8 first passes through the detection channel 32 of the detection block 3 and extends into the first through hole 31 so that the detection image device 2 can take pictures of the filter rod 8. The pictures are then uploaded to the control system for detection and analysis. During the movement of the filter rod 8 into the detection channel 32, the filter rod 8 will, under the action of inertia, fling the glue on itself onto the lens 4. Therefore, the control system will control the solenoid valve to open every minute, and the air source will supply air to the cleaner 7 through the air pipe 72. Compressed air will be sprayed out through the air outlet 71, blowing on the lower surface of the lens 4 to remove dust and glue residue, keeping the lens 4 clean. After the compressed air sprayed by the cleaner 7 cleans the lens 4, a small amount of glue residue may still remain on the lens 4. Therefore, the control system will control the motor 64 to start every 10 minutes. The lead screw 63, driven by the motor 64, rotates around its own axis, and then drives the scraping brush 5 sleeved on the lead screw 63 to the first position (e.g., Figure 5 The position of the squeegee brush 5 shown) and the second position (as shown) Figure 6The scraper brush 5 moves back and forth along the Y direction between the positions shown (as indicated) to scrape off the small amount of adhesive residue remaining on the lens 4. The first and second positions represent the extreme positions of the scraper brush 5. When the scraper brush 5 moves to the first and second positions, it is outside the detection area of ​​the imaging device 2. Since the control system opens the solenoid valve every 10 minutes, the blower 7 simultaneously sprays compressed air to blow away the adhesive residue scraped off by the scraper brush 5. When the scraper brush 5 is not in operation, it remains in the first position. Through the coordinated action of the blower 7 and the reciprocating scraper brush 5, automated cleaning of the lens 4 of the filter rod imaging detection device is achieved, thereby improving the detection accuracy of the imaging detection device.

[0059] Furthermore, the cleaning blower 7 does not affect the inspection work of the inspection imager 2 during the cleaning of the lower surface of the lens 4. However, the scraper brush 5 will affect the inspection work of the inspection imager 2 when cleaning the lower surface of the lens 4. Therefore, the control system controls the cleaning blower 7 to clean the lens 4 every 1 minute and controls the scraper brush 5 to clean the lens 4 every 10 minutes. The inspection work of the inspection imager 2 is paused when the scraper brush 5 is working. This ensures that the dirt on the lens 4 can be cleaned in a timely manner and reduces the number of times the inspection imager 2 is stopped. In this way, production efficiency is guaranteed without affecting the normal production of filter rods.

[0060] It should be noted that the duration of the blowing of the cleaning blower 7 and the number of times the scraper brush 5 moves back and forth can be set according to actual production needs.

[0061] In some implementations, the area of ​​the air outlet 71 is larger than the area of ​​the detection area of ​​the image sensor 2, so as to ensure that the compressed air can clean the detection area of ​​the image sensor 2 corresponding to the lens 4.

[0062] Optionally, such as Figure 3 As shown, the imaging device 2 is detachably connected to the bracket 1. For example, the bracket 1 is provided with a strip hole 11 extending in the Y direction, and a bolt (not shown in the figure) is provided in the strip hole 11. The imaging device 2 is connected to the bracket 1 by the bolt.

[0063] The imaging detection device of this utility model, by setting a strip hole 11, allows the detection imager 2 to adjust its installation position along the Y direction so that the filter rod 8 is located as centrally as possible in the detection area of ​​the detection imager 2, thereby improving the detection accuracy.

[0064] In some implementations, reference Figure 1 , Figure 2 and Figure 3An imaging detection device further includes a laser generator 9, located below the detection block 3. The laser generator 9 emits a laser beam toward the first through hole 31. When the filter rod 8 passes through the detection channel 32 and extends into the first through hole 31, the laser beam irradiates the filter rod 8. By setting the laser generator 9, this application can irradiate the filter rod 8 with a laser beam, thereby enhancing the contrast of the detection image instrument 2 in recognizing the filter rod 8 and improving the detection accuracy.

[0065] It should be noted that in the examples and description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0066] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
