Description

Technical Field

[0001] The invention relates to the technical field of airbag cloth detection, and in particular to an airbag cloth density detection device based on visual detection. Background Art

[0002] Airbag fabric is a key material used in the manufacture of automotive airbags. It is mainly made of polyamide and polyester filaments. Airbag fabric has multiple tests, including physical property tests and mechanical impact tests, in order to detect whether the airbag fabric is qualified after being subjected to a series of impact tests to ensure the performance of the airbag fabric under extreme conditions.

[0003] The prior art discloses a Chinese patent with application number CN202322756746.2, which is an airbag mesh surface hardness testing device. It discloses that after the airbag mesh is fixed on the two support plates, the electric push rod is controlled to drive the pressure head to move downward to press down the surface of the airbag mesh. A pressure sensor is provided inside the pressure head, and the pressure head is used to puncture the mesh to detect the compressive resistance of the surface hardness when the mesh is damaged.

[0004] The above device can only detect the hardness of the airbag cloth when it is under pressure, but cannot test the tearing force of both sides of the airbag cloth. In addition, a large amount of cloth fibers and dust will be generated during the airbag cloth test. If the cloth fibers cannot be cleaned in time, it will affect the effect of the airbag cloth performance test. In addition, the above device can only detect a single detection point of the airbag cloth, which cannot meet the requirements of multi-point detection of a large area of ​​the airbag cloth, and thus the detection range is not comprehensive.

[0021] 4. In the present invention, when the rotating rod rotates to make the scraping teeth perform a scraping test on the upper and lower surfaces of the airbag cloth, the upper rotating rod synchronously drives the cam to rotate. When the cam rotates, it intermittently squeezes the slide. At this time, the slide drives the sliding part to slide back and forth in the sliding groove. When the sliding part slides, it drives the piston rod to perform suction in the suction cylinder. At this time, the gas in the suction cylinder is transmitted to the upper and lower cleaning cylinders through the upper and lower connecting pipes respectively. The upper and lower cleaning cylinders clean the fibers and dust on the upper and lower surfaces of the airbag cloth. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] A density detection device for airbag cloth based on visual detection. The density detection device analyzes the airbag cloth through image processing technology using an existing detector. The present invention tests and analyzes the airbag cloth after the material has been subjected to a mechanical impact test and a physical property test.

[0038] like Figure 1-Figure 11As shown, it includes a bottom plate 1, two symmetrically arranged vertical plates 10 are installed on the rear side of the upper end surface of the bottom plate 1, a rectangular plate 11 with a circular ring in the middle is fixedly installed on the front side of the vertical plate 10, a rotating cylinder 12 is installed in the middle of the vertical plate 10 through a motor, and the rotating cylinders 12 on the two vertical plates 10 respectively perform the airbag cloth retraction and release cooperation operations, and the two rotating cylinders 12 are respectively provided with extension frames 13 fixedly connected to the vertical plates 10 on both sides on the far side, and the extension frames 13 on both sides are provided with the corresponding rotating cylinder 12 outside A flip sleeve 134 is arranged, and a rear plate 14 is fixedly installed on the rear sides of the two vertical plates 10. An impact unit 2 for detecting the hardness of the airbag cloth is fixedly installed on one side of the rear plate 14. A scraping unit 3 for detecting the double-sided wear resistance of the airbag cloth is arranged on the other side of the rear plate 14. The scraping unit 3 is also provided with a cleaning component for cleaning cloth fibers and dust generated when the surface of the airbag cloth is detected. A detection unit 4 fixedly connected to the rear plate 14 is provided on the scraping unit 3 away from the impact unit 2.

[0039] The two rotating cylinders 12 rotate synchronously, so as to coordinate the retraction and expansion of the airbag cloth, so as to realize continuous performance testing of the airbag cloth. The impact unit 2 can be set to perform a mechanical impact test on the airbag cloth to detect the mechanical impact performance of the airbag cloth, and the upper and lower surfaces of the airbag cloth can be scraped synchronously by the scraping unit 3 to simulate the tearing force of the airbag cloth and simultaneously clean the cloth fibers and dust generated during the test of the airbag cloth. The detection unit 4 can perform visual density detection on multiple surfaces of the airbag cloth in a circumferential direction.

[0040] An inclined groove 110 is provided on the adjacent side of the two rectangular plates 11 , a moving block 111 is slidably installed in the inclined groove 110 , a spring is installed between the moving block 111 and the inclined groove 110 , and a pressing roller 112 is rotatably installed on the front side of the moving block 111 .

[0041] The spring squeezes the moving block 111 to slide in the inclined groove 110, so that the diameter of the airbag cloth changes continuously when it is wound and unwound, and the pressing roller 112 on the moving block 111 always presses the airbag roll, thereby effectively preventing the airbag roll from loosening during winding, unwinding and testing. The pressing roller 112 can also guide the airbag cloth when it is wound and unwound to prevent the airbag cloth from deflecting.

[0042] A driving rod 131 is rotatably installed in the middle of the extension frame 13 through an electric slider, and a transfer frame 132 slidably connected to the extension frame 13 is rotatably installed on the driving rod 131. A rotating tooth 133 is rotatably installed in the middle of the transfer frame 132 through an electric slider, and a flip sleeve 134 is rotatably connected to the front side of the transfer frame 132. One side of the rotating tooth 133 is meshed with an opening and closing tooth 135 fixedly connected to the flip sleeve 134, and a notch for guiding the airbag cloth is opened on one side of the flip sleeve 134.

[0043] The electric slider is opened to drive the driving rod 131 to rotate. When the driving rod 131 rotates, it drives the transfer frame 132 to move toward the rotating cylinder 12 until the inner side of the flip sleeve 134 contacts one side of the rolled airbag cloth, and the notch on the flip sleeve 134 can also limit the stretched airbag cloth, thereby strengthening the restriction of the airbag cloth during rolling, and further avoiding the misalignment and looseness of the airbag cloth during rolling. When the flip sleeve 134 moves out of the rotating cylinder 12, the electric slider is opened to drive the rotating teeth 133 to rotate. When the rotating teeth 133 rotate, they drive the opening and closing teeth 135 to rotate through meshing. When the opening and closing teeth 135 rotate, they drive the flip sleeve 134 to flip, thereby facilitating the airbag cloth that has been rolled up on the rear side of the flip sleeve 134 to be moved out along the rotating cylinder 12.

[0044] The impact unit 2 includes a fixed frame 21, a slide groove is provided in the middle of the upper end surface of the fixed frame 21, a control frame 210 is slidably installed in the slide groove through an electric slider, a stretching plate 211 is rotatably installed in the middle of the control frame 210, and regulating rods 212 are rotatably installed on both sides of the fixed frame 21 through the electric slider, and a connecting frame 213 slidably connected to the fixed frame 21 is threadedly rotatably installed on the regulating rod 212, and center plates 22 are fixedly installed on both sides of the upper end surface of the fixed frame 21, and guide wheels 221 are fixedly installed on one side of the upper part of the center plates 22 on both sides away from each other, and a flip frame 23 is rotatably installed in the middle of the two center plates 22, and retracting wheels 231 are symmetrically installed on one side of the flip frame 23, and the other side of the flip frame 23 is hinged to the stretching plate 211.

[0045] A center frame 24 is commonly installed on the side of the two connecting frames 213 away from the fixed frame 21. Corrugated grooves 241 are provided on both sides of the center frame 24. An impact frame 242 is slidably installed in the middle of the center frame 24. Impact plates 243 are commonly installed in the corrugated grooves 241 on both sides through round rods. Rectangular grooves are provided on both sides of the upper end surface of the impact plate 243. A slide plate fixedly connected to the impact frame 242 is slidably installed in the rectangular groove. Springs are sleeved on both sides of the impact frame 242 and the springs are located between the slide plate and the center frame 24.

[0046] When the airbag cloth is subjected to a mechanical impact test, the electric slider is opened to drive the control frame 210 to slide in the slide groove. When the control frame 210 slides, the tensile plate 211 drives the flip frame 23 to flip. When the flip frame 23 flips, the retractable wheel 231 is flipped and lifted. At this time, the pull rope 26 away from the side of the retractable wheel 231 drives the impact plate 234 to move downward. At this time, the spring set on the impact frame 242 intensifies the falling speed of the impact plate 243. When the impact plate 243 falls, the impact rod 25 below it impacts the surface of the airbag cloth, and through the corrugated groove 241 and the springs on both sides of the center frame 24, the impact plate 243 is pulled downward. When the impact rod 25 impacts the airbag cloth, the impact rod 25 and the impact plate 243 impact the airbag cloth multiple times due to the reaction force of the airbag cloth, further intensifying the number of impacts on the airbag cloth, and through the arrangement of the rectangular groove and the slide plate on the impact plate 243, when the impact frame 242 moves down and the impact plate 243 drives the impact rod 25 to impact the airbag cloth, the impact plate 243 can also slide back and forth, thereby enabling the impact rod 25 to slide back and forth when impacting the airbag cloth up and down, further intensifying the impact range of the impact rod 25 when performing a mechanical impact test on the surface of the airbag cloth.

[0047] Springs are provided on both sides of the center frame 24 and the springs are respectively connected to the round rods on both sides. Telescopic plates 244 are fixedly installed on both sides of the upper end surface of the impact frame 242, and an impact rod 25 is arranged on the lower end surface of the impact frame 242. The telescopic ends of the telescopic plates 244 on both sides penetrate and slide in the impact frame 242. A cleaning plate 245 is fixedly installed on the two telescopic plates 244. A circular hole is opened on the cleaning plate 245 for sleeved on the outside of the impact rod 25. Pull ropes 26 are symmetrically installed on the left and right sides of the middle of the upper end surface of the impact plate 243. The pull ropes 26 are respectively wound around the corresponding guide wheels 221 and the end of the pull rope 26 away from the impact plate 243 is fixedly connected to the corresponding retractable wheel 231.

[0048] When the cloth fibers remaining on the impact rod 25 are to be quickly cleaned, the telescopic plates 244 on both sides are opened and pushed forward. At this time, the telescopic plates 244 on both sides drive the cleaning plates 245 to move downward. When the cleaning plates 245 move downward, the circular holes on the cleaning plates 245 quickly scrape off and clean the cloth fibers wrapped around the impact rod 25, thereby preventing the cloth fibers remaining on the impact rod 25 from affecting the impact test of the airbag cloth.

[0049] The scraping unit 3 includes a support plate 31, on the middle part of the front side of the support plate 31 are fixedly installed two groups of extension rods 32 arranged up and down, on the extension rods 32 are rotatably installed a rotating plate 33, a group of upper and lower rotating plates 33 are provided with a middle groove on the adjacent side, a movable plate 331 is slidably installed in the middle groove, a group of two movable plates 331 are respectively fixedly installed with scraping teeth 35 on the adjacent side, the scraping teeth 35 between the upper and lower movable plates 331 are staggered and pressure sensors are provided on the scraping teeth 35, rectangular grooves connected to the middle groove are provided on both sides of the rotating plate 33, the rectangular grooves pass through both sides of the movable plate 331, and electric push rods 332 are fixedly installed on both sides of the rotating plate 33.

[0050] When scraping the airbag cloth, the electric slider is opened to drive the upper and lower rotating rods 34 to rotate synchronously relative to each other. When the two rotating rods 34 rotate, they drive the upper and lower squeezing wheels 341 to rotate. When the upper and lower squeezing wheels 341 rotate, they intermittently squeeze the upper and lower rotating plates 33. At this time, under the action of the spring and the squeezing wheel 341, the upper and lower rotating plates 33 rotate synchronously. At this time, the moving plates 331 in the upper and lower rotating plates 33 respectively drive the scraping teeth 35 to scrape the upper and lower surfaces of the airbag cloth. The pressure sensor in the scraping teeth 35 can monitor the pressure of the airbag cloth during scraping in real time, and the moving plate 331 is driven to slide in the middle groove by the extension and retraction of the electric push rod 332, so that the strength of the scraping teeth 35 on the moving plate 331 when scraping the airbag cloth can be adjusted.

[0051] The telescopic end of the electric push rod 332 is fixedly connected to the moving plate 331, and a central groove 333 is provided on each of the two rotating plates 33 of a group. A slide plate is slidably installed in the central groove 333, and a synchronous plate 334 is hinged on the slide plate. The upper and lower synchronous plates 334 are respectively connected to the upper and lower rotating plates 33 of another group. Two upper and lower symmetrical rotating rods 34 are rotatably installed on one side of the support plate 31 through an electric slider, and an extrusion wheel 341 is fixedly installed on the rotating rod 34. The upper extrusion wheel 341 is always in contact with the upper and lower rotating plates 33 of a group respectively. A fixed block fixedly connected to the support plate 31 is provided on one side of the two rotating plates 33 of a group, and a spring is commonly connected between the fixed block and the corresponding rotating plate 33.

[0052] Through the arrangement of the central groove 333 and the synchronous plate 334, when the extrusion wheel 341 squeezes one group of two rotating plates 33, the upper and lower synchronous plates 334 synchronously drive the other group of two rotating plates 33 to rotate, so that the scraping teeth 35 in the multiple groups of rotating plates 33 perform a large-area scraping test on the airbag cloth, and the upper and lower groups of scraping teeth 35 are staggered to make them scrape the airbag cloth at multiple points, and the physical properties of the airbag cloth are tested by scratching it. When the airbag cloth is scratched, the breaking strength, breaking elongation and breaking force of the airbag cloth are all tested, thereby effectively ensuring the performance of the airbag cloth under extreme conditions.

[0053] The cleaning assembly includes a cam 342, which is located at the rear side of the support plate 31 and fixedly connected to the upper rotating rod 34. A slide 343 slidably connected to the support plate 31 is provided on one side of the cam 342, and a sliding groove 344 is provided on one side of the slide 343. A sliding member 345 fixedly connected to the slide 343 is provided in the sliding groove 344.

A suction cylinder 37 fixedly connected to the support plate 31 is provided below the sliding groove 344. A piston rod 371 fixedly connected to the sliding member 345 is slidably installed in the suction cylinder 37, and a spring is sleeved on the outer side of the piston rod 371. Connecting pipes 372 are fixedly installed on the upper and lower sides of the suction cylinder 37, and the upper and lower connecting pipes 372 are respectively connected to the upper and lower cleaning cylinders 361.

[0054] When the rotating rod 34 rotates to make the scraping teeth 35 perform a scraping test on the upper and lower surfaces of the airbag cloth, the upper rotating rod 34 synchronously drives the cam 342 to rotate. When the cam 342 rotates, it intermittently squeezes the slide 343. At this time, the slide 343 drives the sliding member 345 to slide back and forth in the sliding groove 344. When the sliding member 345 slides, it drives the piston rod 371 to perform suction in the suction cylinder 37. At this time, the gas in the suction cylinder 37 is transmitted to the upper and lower cleaning cylinders 361 through the upper and lower connecting pipes 372 respectively. The upper and lower cleaning cylinders 361 clean the fibers and dust on the upper and lower surfaces of the airbag cloth.

[0055] The detection unit 4 includes a sliding frame 41, which is slidably connected to the rear plate 14 via an electric slider. A detector 42 (model: YX-QC-QWF) is annularly installed on the inner wall of the circular ring of the sliding frame 41 away from the rear plate 14.

[0056] When the tested airbag cloth enters the circular ring in the middle of the sliding frame 41, the detector 42 arranged in the annular direction performs a visual density inspection on the passing airbag cloth.

[0057] When the present invention is in use, the traction end of the airbag cloth passes through two groups of rotating plates 33 arranged up and down, between two cleaning cylinders 361, and the middle part of the ring on the sliding frame 41 in sequence, and is finally wound on the rotating cylinder 12 on one side. The spring squeezes the moving block 111 to slide in the inclined groove 110, so that the airbag cloth changes continuously in diameter during winding and unwinding, and the pressing roller 112 on the moving block 111 always presses the airbag roll, thereby effectively preventing the airbag roll from loosening during winding, unwinding and testing. In addition, the pressing roller 112 can also guide the airbag cloth during winding and unwinding to prevent the airbag cloth from deflecting. The electric slider is opened to drive the driving rod 131 to rotate, and the driving rod When 131 rotates, it drives the transfer frame 132 to move toward the rotating cylinder 12 until the inner side of the flip sleeve 134 contacts one side of the rolled airbag cloth, and the notch on the flip sleeve 134 can also limit the stretched airbag cloth, thereby strengthening the restriction of the airbag cloth during rolling, and further avoiding the dislocation and looseness of the airbag cloth during rolling. When the flip sleeve 134 moves out of the rotating cylinder 12, the electric slider is turned on to drive the rotating teeth 133 to rotate. When the rotating teeth 133 rotate, they drive the opening and closing teeth 135 to rotate through meshing. When the opening and closing teeth 135 rotate, they drive the flip sleeve 134 to flip, so as to facilitate the airbag cloth rolled up at the rear side of the flip sleeve 134 to be moved out along the rotating cylinder 12.

[0058] The electric slider is opened to drive the control frame 210 to slide in the slide groove. When the control frame 210 slides, the tensile plate 211 drives the flip frame 23 to flip. When the flip frame 23 flips, the retractable wheel 231 is flipped and lifted. At this time, the pull rope 26 away from the side of the retractable wheel 231 drives the impact plate 234 to move downward. At this time, the spring set on the impact frame 242 intensifies the falling speed of the impact plate 243. When the impact plate 243 falls, the impact rod 25 below it impacts the surface of the airbag cloth, and through the setting of the corrugated groove 241 and the springs on both sides of the center frame 24, when the impact rod 25 When impacting the airbag cloth, the impact rod 25 and the impact plate 243 impact the airbag cloth multiple times due to the reaction force of the airbag cloth, further increasing the number of impacts on the airbag cloth. Moreover, through the arrangement of the rectangular groove and the slide plate on the impact plate 243, when the impact frame 242 moves down and the impact plate 243 drives the impact rod 25 to impact the airbag cloth, the impact plate 243 can also slide forward and backward, thereby enabling the impact rod 25 to slide forward and backward when impacting the airbag cloth up and down, further increasing the impact range of the impact rod 25 when performing a mechanical impact test on the surface of the airbag cloth.

[0059] The telescopic plates 244 on both sides are opened and pushed forward. At this time, the telescopic plates 244 on both sides drive the cleaning plates 245 to move downward. When the cleaning plates 245 move downward, the circular holes on the cleaning plates 245 quickly scrape off and clean the fabric fibers wrapped around the impact rod 25, thereby preventing the fabric fibers remaining on the impact rod 25 from affecting the impact test of the airbag fabric.

[0060] The electric slider is opened to drive the upper and lower rotating rods 34 to rotate synchronously relative to each other. When the two rotating rods 34 rotate, the upper and lower squeezing wheels 341 are driven to rotate. When the upper and lower squeezing wheels 341 rotate, they intermittently squeeze the upper and lower rotating plates 33. At this time, the upper and lower rotating plates 33 rotate synchronously under the action of the spring and the squeezing wheel 341. At this time, the moving plates 331 in the upper and lower rotating plates 33 respectively drive the scraping teeth 35 to scrape the upper and lower surfaces of the airbag cloth. The pressure sensor (model: PT124G-116) in the scraping teeth 35 can monitor the pressure of the airbag cloth in real time during the scraping. The moving plate 331 is driven to slide in the middle groove by the extension and contraction of the electric push rod 332, so that the force of the scraping teeth 35 on the moving plate 331 when scraping the airbag cloth can be adjusted.

[0061] Through the arrangement of the central groove 333 and the synchronous plate 334, when the extrusion wheel 341 squeezes the two rotating plates 33 of one group, the upper and lower synchronous plates 334 synchronously drive the two rotating plates 33 of the other group to rotate, so that the scraping teeth 35 in the multiple groups of rotating plates 33 perform a large-area scraping test on the airbag cloth, and the upper and lower groups of scraping teeth 35 are staggered to scrape the airbag cloth at multiple points. By scraping the airbag cloth, its physical properties are tested. When the airbag cloth is scraped, the breaking strength, breaking elongation and breaking force of the airbag cloth are all tested. Thereby effectively ensuring the performance of the airbag cloth under extreme conditions, the upper rotating rod 34 synchronously drives the cam 342 to rotate, and the cam 342 intermittently squeezes the slide 343 when rotating. At this time, the slide 343 drives the sliding member 345 to slide back and forth in the sliding groove 344, and the sliding member 345 drives the piston rod 371 to suck in the suction cylinder 37 when sliding. At this time, the gas in the suction cylinder 37 is transmitted to the upper and lower cleaning cylinders 361 through the upper and lower connecting pipes 372 respectively, and the upper and lower cleaning cylinders 361 clean the fibers and dust on the upper and lower surfaces of the airbag cloth.
