Description

Technical Field

[0001] The present invention belongs to the field of tightness detection, and particularly relates to a tightness detection device for aerosol generating articles. Background Art

[0002] The tightness detection device for aerosol generating articles is a special testing equipment for products such as electronic cigarettes and inhalable drug devices, mainly used to evaluate the physical structure stability of key components, such as the joint between the cartridge and the cigarette stick and the filter assembly part, etc. This device simulates the plugging, unplugging, squeezing and other actions of users in actual use through a robotic arm, applies longitudinal tensile force or lateral pressure, and accurately measures the force value required for component separation, so as to detect parameters such as connection strength and material density. Its core function lies in controlling key performance indicators such as the uniformity of aerosol release and inhalation resistance, ensuring that the product assembly quality meets the standards, and avoiding affecting the user experience and product safety due to the components being too loose or too tight.

[0003] In the existing tightness detection of aerosol generating articles, the product and the plug-in are usually fixed on two fixtures respectively, and the top fixture is driven by a cylinder to rise, so that the top fixture drives the plug-in to separate from the product. However, there are some problems that cannot be ignored in this conventional detection method:

[0004] 1. When the top fixture fixes the plug-in, once the clamping force applied to the plug-in is too large, it is easy to cause local stress concentration and deformation of the plug-in. After the plug-in is deformed, it forms a secondary interference fit with the product to be measured, making the separation force data contain false components;

[0005] 2. Using a cylinder to push the top fixture for single separation has a difference in mechanical behavior from the multiple pluggings and unplugging of the plug-in in actual use. In actual use, the plug-in may experience multiple insertions and extractions, resulting in material fatigue, wear or deformation, thus affecting the connection tightness. However, the single separation test of the cylinder cannot capture these cumulative effects, resulting in low accuracy of the detection results.

[0006] Therefore, those skilled in the art have proposed a tightness detection device for aerosol generating articles to solve the problems raised in the background art. Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a tightness detection device for aerosol generating articles to solve the problems that in the prior art, the tightness detection device is prone to applying too large a clamping force to the plug-in during the test, resulting in deformation of the plug-in and thus generating false separation data, and unable to simulate the cumulative effect obtained from multiple pluggings and unplugging, affecting the accuracy of the detection results.

[0033] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0034] As shown in the attached Figure 1 to the attached Figure 7 figure:

[0035] The present invention provides a tightness detection device for an aerosol generating article, which includes a detection frame 1, a fixing component 2, a detection component 3, and a plugging and unplugging simulation mechanism 4. The detection frame 1 is composed of a top plate 11, a bottom plate 12, and side plates 13 on both sides. The top plate 11 and the bottom plate 12 are both horizontally arranged, and the side plates 13 are arranged on both sides between the top plate 11 and the bottom plate 12. A fixing component 2 is arranged inside the detection frame 1. The fixing component 2 includes a first fixing member 21 and a second fixing member 22. The first fixing member 21 is used for clamping and fixing the plug of the aerosol generating article, and the second fixing member 22 is used for clamping and fixing the aerosol generating article. A detection component 3 is movably arranged above the first fixing member 21. On the one hand, the detection component 3 drives the first fixing member 21 to clamp the top cover and then move upward. On the other hand, it measures the resistance during the upward movement to judge the tightness of the assembly of the aerosol generating article. The plugging and unplugging simulation mechanism 4 is arranged inside the detection frame 1 above the first fixing member 21. The plugging and unplugging simulation mechanism 4 is used to drive the first fixing member 21 to reciprocally lift and lower to simulate the strain state of the aerosol generating article and the plug after frequent plugging and unplugging.

[0036] Reference Figure 2 , the first fixing member 21 includes a fixing frame 211, a first cylinder 212, a sliding plate 213, a first clamping plate 214, a pressure sensor 215, an isolation spring 216, and a horizontal shaft 217. First cylinders 212 are symmetrically installed at both ends of the fixing frame 211. The output ends of the two groups of first cylinders 212 pass through the fixing frame 211 and are connected to a sliding plate 213 that is slidably connected to the inside of the fixing frame 211. Horizontal shafts 217 are symmetrically slidably penetrated through the sliding plate 213. One ends of the two groups of horizontal shafts 217 are connected to anti - detachment discs 218, and the other ends between the two groups of horizontal shafts 217 are connected to a first clamping plate 214. Isolation springs 216 for separating the first clamping plate 214 and the sliding plate 213 are sleeved on the two groups of horizontal shafts 217. A pressure sensor 215 is arranged on the side of the sliding plate 213.

[0037] Among them, the two sliding plates 213 are driven by the first cylinder 212 to move towards each other inside the fixing frame 211. The two sliding plates 213 drive the two first clamping plates 214 to move synchronously, so that the two first clamping plates 214 contact the outer wall of the plug to be fixed. At this time, when the sliding plate 213 continues to move, the two first clamping plates 214 will squeeze the isolation spring 216 and thus approach the sliding plate 213 to contact the pressure sensor 215. That is, the clamping force can be measured in real - time through the pressure sensor 215 to avoid the clamping force exceeding the set threshold, resulting in deformation of the plug and false data. The set threshold refers to the yield strength parameter of the plug material. At the same time, by adjusting the clamping force in real - time to be closest to the set threshold, that is, by increasing the lateral load force to simulate the tightness limit load during violent separation.

[0038] Reference Figure 7, the second fixing member 22 includes a fixing base 221, a second air cylinder 222 and a second clamping plate 223. The fixing base 221 is installed on the bottom plate 12. The two ends of the fixing base 221 are provided with second air cylinders 222. The output end of the second air cylinder 222 passes through the fixing base 221 and is connected with the second clamping plate 223. The two groups of second clamping plates 223 are both slidably connected to the inner wall of the fixing base 221.

[0039] Among them, the second air cylinder 222 drives the second clamping plate 223 to approach the aerosol generating article, so as to stably clamp the aerosol generating article.

[0040] Reference Figure 2 and Figure 7 , the opposite sides of the two groups of first clamping plates 214 and the opposite sides of the two groups of second clamping plates 223 are both set as trapezoidal clamping surfaces, and rubber pads are arranged on the trapezoidal clamping surfaces.

[0041] Among them, the trapezoidal clamping surface facilitates the clamping of the cylindrical aerosol generating article, expands the contact area between the two, and the rubber pad increases the frictional force of the clamping, improving the stability of the clamping.

[0042] Reference Figure 2 and Figure 3 , the detection assembly 3 includes a moving plate 31, a vertical shaft 32, a compression spring 33, a pressure sensing ring 34 and a pressing plate 35. Four groups of limit columns 5 are symmetrically arranged between the top plate 11 and the bottom plate 12. The moving plate 31 is slidably arranged between the four groups of limit columns 5. Two vertical shafts 32 are symmetrically and slidably penetrated through the moving plate 31. The bottom ends of the two vertical shafts 32 are respectively connected to the two ends of the top of the fixed frame 211. The top ends of the two vertical shafts 32 are connected with a pressing plate 35. Two pressure sensing rings 34 located outside the vertical shafts 32 are symmetrically installed on the moving plate 31. A compression spring 33 sleeved outside the vertical shaft 32 is abutted between the pressure sensing ring 34 and the pressing plate 35.

[0043] Reference Figure 1 , the detection assembly 3 further includes a plugging and unplugging air cylinder 36. The plugging and unplugging air cylinder is installed at the bottom of the top plate 11. The plugging and unplugging air cylinder 36 is connected with the moving plate 31 through a plugging and unplugging simulation mechanism 4.

[0044] Among them, the insertion and extraction cylinder 36 drives the moving plate 31 to descend. During the descent of the moving plate 31, the fixed frame 211 is driven to move to the outside of the plug through the vertical shaft 32, and then the plug is clamped by the first fixing member 21. After the clamping is completed, the insertion and extraction cylinder 36 drives the moving plate 31 to rise. During the rise of the moving plate 31, since the fixed frame 211 and the plug are in a stable clamping state, the fixed frame 211 will squeeze the compression spring 33 through the vertical shaft 32. The compression spring 33 undergoes elastic contraction and squeezes the pressure sensing ring 34 until the plug is separated from the aerosol generating article. The maximum separation force value is measured by the pressure sensing ring 34, and the tightness of the connection between the plug and the aerosol generating article is judged through the value. The detection method is simple and the detection result is relatively intuitive.

[0045] Reference Figure 5 and Figure 6 The insertion and extraction simulation mechanism 4 includes a mounting frame 41, a driving member 42, a rotating rod 43, a rotating shaft 44 and a pull rod 45. The mounting frame 41 is connected to the output end of the insertion and extraction cylinder 36. The rotating shaft 44 is rotatably penetrated through the middle of the mounting frame 41. The driving member 42 is arranged in the middle of the rotating shaft 44. The rotating rod 43 is connected to both ends of the rotating shaft 44. The pull rod 45 is rotatably connected to the outside of one end of the two rotating rods 43 away from the rotating shaft 44. The two ends of the two pull rods 45 away from the rotating rod 43 are respectively rotatably connected to both sides of the top of the moving plate 31.

[0046] Among them, the driving member 42 drives the rotating shaft 44 to rotate. During the rotation of the rotating shaft 44, the rotating rod 43 is driven to rotate. During the rotation of the rotating rod 43, one end of the pull rod 45 is driven to do a circular motion, and the other end of the pull rod 45 drives the moving plate 31 to do a reciprocating lifting motion. During the reciprocating lifting of the moving plate 31, the fixed frame 211 can be driven to fix the plug and reciprocally insert and extract it from the aerosol generating article, so as to simulate the dynamic impact loading insertion and extraction of the plug for multiple times, and thus the change of tightness after multiple insertions and extractions can be detected more accurately.

[0047] Reference Figure 6 The driving member 42 includes a motor 421, a driving gear 422 and a driven gear 423. The motor 421 is installed on the inner wall of the mounting frame 41. The output shaft of the motor 421 is connected to the driving gear 422. The driving gear 422 is meshed and connected with a driven gear 423 on one side. The driven gear 423 is installed on the rotating shaft 44.

[0048] Among them, the motor 421 drives the driving gear 422 to rotate. The driving gear 422 is meshed with the driven gear 423, and the rotating shaft 44 is driven to rotate under the action of the meshing force.

[0049] Working principle: When in use, place the aerosol generating article between the two second clamping plates 223. Drive the second clamping plates 223 to approach the aerosol generating article through the second cylinder 222, so as to stably clamp the aerosol generating article. Insert the plug on the aerosol generating article. Then drive the moving plate 31 to descend through the plugging and unplugging cylinder 36. During the descent of the moving plate 31, drive the fixed frame 211 to move to the outside of the plug through the vertical shaft 32. Drive the two sliding plates 213 to move towards each other in the fixed frame 211 through the first cylinder 212. The two sliding plates 213 drive the two first clamping plates 214 to move synchronously, so that the two first clamping plates 214 contact the outer wall of the plug to be fixed. At this time, the sliding plates 213 continue to move. On the one hand, the two first clamping plates 214 firmly clamp the plug. On the other hand, they will squeeze the isolation spring 216 and thus approach the sliding plates 213 to contact the pressure sensor 215. Thus, the pressure sensor 215 can be used to measure the real-time clamping force. After the clamping is completed, the plugging and unplugging cylinder 36 drives the moving plate 31 to rise. During the rising process of the moving plate 31, since the fixed frame 211 and the plug are in a stable clamping state, the fixed frame 211 will squeeze the compression spring 33 through the vertical shaft 32. The compression spring 33 undergoes elastic contraction and squeezes the pressure sensing ring 34 until the plug is separated from the aerosol generating article. Use the pressure sensing ring 34 to measure the maximum separation force value, and judge the tightness of the connection between the plug and the aerosol generating article through the value. When it is necessary to detect the change in tightness after multiple pluggings and unplugging, drive the driving gear 422 to rotate through the motor 421. The driving gear 422 meshes with the driven gear 423, and drives the rotating shaft 44 to rotate under the action of the meshing force. During the rotation of the rotating shaft 44, drive the rotating rod 43 to rotate. During the rotation of the rotating rod 43, drive one end of the pull rod 45 to perform a circular motion. The other end of the pull rod 45 drives the moving plate 31 to perform a reciprocating lifting motion. During the reciprocating lifting of the moving plate 31, the fixed frame 211 can be driven to repeatedly plug and unplug the plug after fixing it with the aerosol generating article, so as to simulate the multiple dynamic impact loading plugging and unplugging of the plug, and thus can more accurately detect the change in tightness after multiple pluggings and unplugging.
