Description

Technical Field

[0001] This invention relates to the field of surface inspection technology, specifically to an online inspection device and method for surface defects in sealing strips. Background Technology

[0002] Sealing strips are widely used in automobiles, doors and windows, electronic equipment and other fields. Their surface quality directly affects sealing performance and service life. With the continuous improvement of the degree of automation in industrial production, higher requirements are put forward for online detection technology of surface defects of sealing strips.

[0003] Currently, surface defect detection of sealing strips mainly employs visual inspection technology. This involves using a detection head to collect data from the sealing strip surface to identify defects such as scratches, dents, and bubbles. To improve the comprehensiveness of the inspection, adjustable-angle detection devices have emerged, allowing the detection head to cover different surface areas of the sealing strip by adjusting its angle. However, existing online surface defect detection devices for sealing strips still have the following shortcomings: First, when adjusting the detection angle, the detection head cannot always remain facing the sealing strip during the raising and lowering process, leading to a deviation in the detection perspective and affecting the accuracy of the inspection. Second, the detection head can only adjust its orientation angle, not its tilt angle with the sealing strip, making it difficult to adapt to the inspection needs of sealing strips with different shapes. Third, during production, transportation, and storage, the surface of the sealing strip is easily contaminated with dust, debris, and other pollutants. Existing detection devices lack cleaning functions, and these contaminants can interfere with visual inspection, leading to misjudgments or missed detections, thus affecting the accuracy of the inspection results.

[0013] This invention also provides another technical solution: an online detection method for surface defects of sealing strips, using the aforementioned online detection device for surface defects of sealing strips, comprising the following steps: S1. Pass the sealing strip through the middle of the two wheel frames so that the sealing strip is positioned between each set of infeed and outfeed rollers, thus completing the positioning and clamping of the sealing strip; S2. Start the lifting mechanism to move the detection piece up and down. Utilize the limiting position of the detection piece within the guide frame to ensure that the detection head always faces the sealing strip during the lifting process, thus completing the adjustment of the detection angle. S3. Start the dual-axis motor to drive the sliding seat to move around the sealing strip along the ring frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention designs and installs an adjustable angle detection mechanism. Utilizing the cooperation of a first guide groove and a second guide groove, along with the guiding of a sliding rod within the first guide groove and the limiting cooperation of a limiting rod within the second guide groove, the detection head is ensured to always face the sealing strip during the lifting and lowering process of the lifting gear. This solves the problem in existing technologies where the detection head is difficult to maintain a consistent orientation towards the sealing strip when adjusting the angle, thus improving detection accuracy. Furthermore, the design of the connecting frame, movable plate, threaded rod, translation block, and connecting rod allows for the modification of the angle between the connecting frame and the movable plate, enabling precise adjustment of the tilt angle between the detection head and the sealing strip. This adapts to the detection requirements of sealing strips with different shapes, further improving the detection effect. This invention designs and installs a dust collection mechanism, which uses a dual-axis motor to simultaneously drive a circular gear and a dust collection fan. This allows the sliding seat to rotate on a circular track while the dust collection fan rotates to suck up and remove dust adhering to the surface of the sealing strip. This eliminates the interference of dust on the detection of defects on the surface of the sealing strip, and also makes the surface of the sealing strip cleaner, further improving the detection effect. This invention achieves coordinated operation between the dust collection mechanism and the feeding / discharging mechanism by setting an external gear ring on the sliding seat. When the sliding seat moves to the bottom of the annular rail, the external gear ring meshes with the feeding / discharging gear, driving the feeding / discharging rollers to rotate. This eliminates the need for a separate power-driven feeding / discharging mechanism, reducing equipment costs. At the same time, it allows the sealing strip to be fed in a segmented manner, and the detection head can analyze and process the detection data during the feeding interval after data acquisition, facilitating the acquisition of accurate detection results.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figures 1 to 9 As shown, this embodiment provides an online detection device for surface defects of sealing strips, including a device base 1, an adjustable angle detection mechanism 2, a dust suction mechanism 3, and a feeding and discharging mechanism 4.

[0019] like Figures 2 to 4As shown, the adjustable angle detection mechanism 2 includes a gantry frame 201, a lifting rack 205, a guide frame 209, a detection head 217, a first guide groove 210, a second guide groove 211, a slide bar 212, a rotating seat 213, and a limiting rod 216. The gantry frame 201 is located at the top center of the device base 1. The lifting rack 205 is movably installed inside the gantry frame 201. The guide frame 209 is located at the top of the device base 1 and inside the gantry frame 201. The first guide groove 210 and the second guide groove 211 are both opened on the side of the guide frame 209 away from the annular frame 301. The slide rod 212 is slidably installed inside the first guide groove 210. The bottom end of the lifting rack 205 is movably sleeved on the slide rod 212. The rotating seat 213 is movably installed at the end of the slide rod 212 located outside the first guide groove 210. The detection head 217 is installed on the rotating seat 213. One end of the limiting rod 216 is fixedly installed on the rotating seat 213 and the other end is slidably installed inside the second guide groove 211. When the lifting rack 205 is raised and lowered, the guide of the slide rod 212 in the first guide groove 210 and the limiting cooperation of the limiting rod 216 in the second guide groove 211 drive the detection head 217 to always face the sealing strip.

[0020] like Figures 5 to 7 As shown, the vacuuming mechanism 3 includes a ring frame 301, a ring rail 302, a sliding seat 303, an external gear ring 304, a vacuum cylinder 306, a dual-axis motor 310, a vacuum fan 312, a circular gear 313, and an internal gear ring 314. The ring frame 301 is located at the top of the device base 1 and on the side of the gantry 201 away from the detection head 217. The ring rail 302 is fixedly installed on the side of the ring frame 301 near the gantry 201. The sliding seat 303 is slidably installed on the ring rail 302. The external gear ring 304 is located on the outer surface of the sliding seat 303. The dust collection cylinder 306 is located on the side of the sliding seat 303 near the gantry 201. The dual-axis motor 310 is fixedly installed on the sliding seat 303. The dust collection fan 312 is located inside the dust collection cylinder 306. The circular gear 313 is fixedly installed on one end of the output shaft of the dual-axis motor 310. The internal gear ring 314 is fixedly installed on the inner side wall of the ring frame 301 and meshes with the circular gear 313. When the dual-axis motor 310 starts, it drives the sliding seat 303 to rotate through the meshing of the circular gear 313 and the internal gear ring 314. At the same time, it drives the dust collection fan 312 to rotate for suction through the other end of the output shaft.

[0021] like Figure 1 , Figure 8 and Figure 9As shown, the feeding / discharging mechanism 4 includes a support frame 401, a wheel frame 402, a gear shaft 403, two first transmission mechanisms and one second transmission mechanism. Each of the first transmission mechanisms includes two feeding / discharging rollers 404, and the second transmission mechanism includes a transmission rod 410 and a feeding / discharging gear 411. There are two support frames 401, which are fixedly installed at both ends of the device base 1. Each support frame 401 has a wheel frame 402 fixedly installed at its top. Each wheel frame 402 is rotatably connected to two feed rollers 404 and a gear shaft 403. The two feed rollers 404 are arranged vertically. The central axis of the lower feed roller 404 is fixedly connected to the gear shaft 403. The transmission rod 410 is rotatably installed in the middle of the lower part of the ring frame 301. The feed gear 411 is fixedly installed at one end of the transmission rod 410. When the sliding seat 303 moves to the bottom of the ring rail 302, the external gear ring 304 meshes with the feed gear 411 and drives the feed rollers 404 to rotate, realizing the linear feed and discharge of the sealing strip.

[0022] The sealing strip is passed through the middle of the two wheel frames 402, positioning it between each set of infeed and discharge rollers 404, thus completing the sealing strip's positioning and clamping. Turning the first knob 208, the sliding rod 212 guides the first guide groove 210, and the limiting rod 216 limits its position in the second guide groove 211, ensuring the detection head 217 always faces the sealing strip. Starting the dual-axis motor 310 causes the sliding seat 303 to rotate on the annular rail 302, while the vacuum fan 312 rotates to remove dust from the sealing strip's surface. When the sliding seat 303 reaches the bottom of the annular rail 302, the external gear ring 304 meshes with the infeed and discharge gear 411, driving the infeed and discharge rollers 404 to rotate, thus initiating linear feeding and discharging of the sealing strip.

[0023] Example 2

[0024] like Figures 2 to 4 As shown, based on Embodiment 1, this embodiment further includes an adjustable angle detection mechanism 2, which further comprises a translation groove 202, a slide rail 203, a translation seat 204, an adjusting rod 206, a lifting adjusting gear 207, and a first knob 208. The translation groove 202 is located at the top of the gantry frame 201. The slide rail 203 is fixedly installed at the top of the gantry frame 201 and is located on one side of the translation groove 202. One end of the translation seat 204 is slidably installed in the translation groove 202 and the other end is slidably installed on the slide rail 203. The lifting gear 205 is slidably connected in the translation seat 204. The adjusting rod 206 is rotatably installed on the translation seat 204. The lifting adjusting gear 207 is fixedly installed on the end of the adjusting rod 206 near the lifting gear 205 and meshes with the lifting gear 205. The first knob 208 is fixedly installed on the end of the adjusting rod 206 away from the lifting gear 205.

[0025] In this embodiment, by setting a first knob 208, an adjusting rod 206, and a lifting adjusting gear 207, the first knob 208 can be easily turned to drive the lifting adjusting gear 207 to rotate via the adjusting rod 206. The lifting adjusting gear 207 then drives the lifting rack 205 to rise and fall. At the same time, the translation seat 204 moves on the translation groove 202 and the slide rail 203, thus realizing convenient adjustment of the position of the detection head 217.

[0026] Turning the first knob 208 causes the adjusting rod 206 to rotate the lifting adjusting gear 207, which in turn drives the lifting rack 205 to rise and fall. Simultaneously, the translation seat 204 moves horizontally along the translation groove 202 and the slide rail 203. When the lifting rack 205 rises, it drives the rotating seat 213 to rise via the slide rod 212. Guided by the first guide groove 210, the slide rod 212 moves towards the middle top of the guide frame 209, ensuring that the rotating seat 213 keeps the detection head 217 facing the sealing strip. When the lifting rack 205 descends, the slide rod 212 moves towards the lower end of the first guide groove 210. When the translation seat 204 moves to one end of the translation groove 202, the lifting rack 205 continues to descend, causing the slide rod 212 to continue moving towards the lower end of the first guide groove 210, thus achieving continuous angle adjustment of the detection head 217.

[0027] Example 3

[0028] like Figures 2 to 4 As shown, based on Embodiment 1 or Embodiment 2, this embodiment further includes a connecting frame 214, a movable plate 215, a threaded rod 218, a second knob 219, a fixed base 220, a translation block 221, and a connecting rod 222. The connecting frame 214 is fixedly installed on one side of the top of the rotating base 213. One end of the movable plate 215 is movably installed on the side of the connecting frame 214 away from the rotating base 213. The detection head 217 is fixedly installed on the movable plate 215. The threaded rod 218 is rotatably installed on the top of the connecting frame 214. The second knob 219 is fixedly installed on one end of the threaded rod 218. The fixed base 220 is fixedly installed on the top of the movable plate 215. The translation block 221 is threadedly connected to the threaded rod 218. One end of the connecting rod 222 is movably installed on the translation block 221, and the other end is movably connected to the fixed base 220.

[0029] The slide bar 212, rotating seat 213, connecting frame 214, movable plate 215, limiting rod 216, detection head 217, threaded rod 218, second knob 219, fixed seat 220, translation block 221 and connecting rod 222 together constitute the detection component to detect the sealing strip.

[0030] This embodiment uses a connecting frame 214, a movable plate 215, a threaded rod 218, a second knob 219, a translation block 221, and a connecting rod 222. Turning the second knob 219 causes the threaded rod 218 to rotate, and the translation block 221 and the connecting rod 222 cause the movable plate 215 to rotate, changing the angle between the connecting frame 214 and the movable plate 215. This allows for precise adjustment of the tilt angle between the detection head 217 and the sealing strip, adapting to the detection requirements of sealing strips of different shapes.

[0031] Adjust the tilt angle of the detection head 217 according to the detection requirements. By turning the second knob 219, the threaded rod 218 is driven to rotate. When the threaded rod 218 rotates, it drives the translation block 221 to move closer to the second knob 219. At this time, the connecting rod 222 drives the movable plate 215 to rotate away from the connecting frame 214. By changing the angle between the connecting frame 214 and the movable plate 215, the tilt angle between the detection head 217 and the sealing strip is adjusted to adapt to different detection requirements.

[0032] Example 4

[0033] like Figures 5 to 7 As shown, in this embodiment, based on any one of embodiments 1 to 3, the two output shafts of the dual-axis motor 310 further drive the surrounding gear 313 and the vacuum fan 312 respectively. The surrounding gear 313 meshes with the internal gear ring 314 to drive the sliding seat 303 to rotate around the annular track 302. The other output shaft of the dual-axis motor 310 drives the vacuum fan 312 to rotate through the bevel gear transmission, so that the vacuum cylinder 306 draws air from one end near the sealing strip and exhausts air from the other end.

[0034] In this embodiment, a single motor simultaneously drives the circular gear 313 and the vacuum fan 312 by a dual-axis motor 310, thereby simplifying the mechanism structure and reducing equipment costs.

[0035] When the dual-axis motor 310 is started, one output shaft drives the vacuum cleaner 306 to rotate through the meshing of the circular gear 313 and the internal gear ring 314. The other output shaft drives the vacuum fan 312 to rotate through the meshing of the second bevel gear 311 and the first bevel gear 309. This allows a single motor to simultaneously drive vacuuming and the circular motion. The vacuum cleaner 306 is used to suck up the dust attached to the sealing strip, eliminating the interference of dust on the detection of defects on the surface of the sealing strip.

[0036] Example 5

[0037] like Figure 1 , Figure 8 and Figure 9As shown, based on any one of embodiments 1 to 4, this embodiment further includes a first transmission mechanism comprising a synchronous gear 405, a horizontal shaft 406, a first belt 407, a worm gear 408, and a worm 409. There are two synchronous gears 405, arranged vertically and meshing with each other. The two synchronous gears 405 are coaxially arranged with the two feed rollers 404 respectively. The horizontal shaft 406 is movably mounted on the inner bottom end of the support frame 401. The first belt 407 is movably sleeved on the gear shaft 403 and the horizontal shaft 406. The worm gear 408 is fixedly sleeved in the middle of the horizontal shaft 406. The worm 409 is movably mounted on the inner bottom end of the support frame 401 and meshes with the worm gear 408. The second belt 412 is movably sleeved on the transmission rod 410 and the worm 409. The two worms 409 are fixedly connected by a connecting shaft.

[0038] This embodiment achieves the linkage transmission between the external gear ring 304 and the feed roller 404 by setting a synchronous gear 405, a horizontal shaft 406, a first belt 407, a worm gear 408, a worm 409, and a second belt 412, so that the sealing strip is fed in a linear manner, which facilitates the analysis and processing of detection data by the detection head 217 during the feeding interval.

[0039] When the external gear ring 304 moves to the bottom of the annular rail 302, it meshes with the feed gear 411. The transmission rod 410 and the second belt 412 drive the worm gear 409 to rotate, the worm wheel 408 drives the horizontal shaft 406 to rotate, the first belt 407 drives the gear shaft 403 to rotate, and the synchronous gear 405 drives the two feed rollers 404 to rotate in opposite directions, realizing the linear feed and discharge of the sealing strip. This allows the detection head 217 to perform detection and analysis during the feeding interval after data acquisition, so as to obtain accurate detection results.

[0040] Example 6

[0041] like Figures 1 to 9 As shown, this embodiment provides an online detection method for surface defects of sealing strips, using the above-mentioned online detection device, including the following steps: S1. Pass the sealing strip through the middle of the two wheel frames 402, so that the sealing strip is located between each set of infeed and outfeed rollers 404, and complete the positioning and clamping of the sealing strip, providing a stable feeding basis for subsequent testing; S2. Turn the first knob 208 to drive the lifting adjustment gear 207 to rotate through the adjusting rod 206. The lifting adjustment gear 207 drives the lifting rack 205 to rise and fall. By using the guide rod 212 in the first guide groove 210 and the limiting rod 216 in the second guide groove 211 to make the detection head 217 always face the sealing strip during the lifting process, thus completing the adjustment of the detection angle. S3. Turn the second knob 219 to drive the threaded rod 218 to rotate. This, through the translation block 221 and the connecting rod 222, drives the movable plate 215 to rotate, changing the angle between the connecting frame 214 and the movable plate 215. This allows for precise adjustment of the tilt angle between the detection head 217 and the sealing strip, to adapt to different detection requirements. S4. Start the dual-axis motor 310. Through the meshing of the surrounding gear 313 and the internal gear ring 314, the sliding seat 303 moves around the sealing strip along the annular track 302. At the same time, the dust suction fan 312 is driven to rotate through the bevel gear transmission to suck up and remove the dust attached to the surface of the sealing strip, eliminating the interference of dust on the test results. S5. The detection head 217 collects data on the cleaned sealing strip surface to obtain information on surface defects of the sealing strip. S6. When the sliding seat 303 moves to the bottom of the annular rail 302, the external gear ring 304 meshes with the feed gear 411, driving the feed roller 404 to rotate and causing the sealing strip to feed in a linear manner. During the feeding interval, the collected detection data is analyzed and processed to obtain accurate detection results.
