Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a logistics freight packaging damage detection device. BACKGROUND

[0002] In the logistics freight industry, fruits, fresh foods and other perishable goods are usually transported using sealed packaging. The sealing of the packaging directly determines the freshness and transportation loss rate of the goods. Therefore, before freight transfer or loading, sealed packaging needs to be checked for damage to screen out unqualified packaging with leaks or damage, so as to avoid goods from deteriorating or being damaged during transportation. Although traditional mechanical detection equipment has improved detection efficiency to some extent, it still has many technical problems. Firstly, the clamping mechanism of most equipment adopts a rigid fixed structure, which is difficult to adapt to irregular sealed packaging of different shapes and sizes. When clamping, the packaging may be displaced or locally stressed too much, causing the packaging to be damaged. Secondly, the detection process relies on single infrared detection or pressure detection, which has insufficient ability to capture small leaks. The airflow signal generated by small damage is weak, and traditional equipment cannot effectively identify it, resulting in a large number of packaging with potential leakage risks flowing into the transportation link. Thirdly, the equipment process design is complicated. The front and back detection needs to be realized by manually adjusting the packaging posture or switching equipment modules, which not only increases the operation complexity and process switching time, but also reduces the universality of the equipment, making it difficult to adapt to diversified freight packaging detection needs. Therefore, we propose a logistics freight packaging damage detection device. SUMMARY

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described below in conjunction with the drawings and examples. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0031] As Figure 1 - Figure 10As shown, a logistics freight packaging damage detection device includes a frame 1. A flipping mechanism 2 is installed inside the frame 1. The flipping mechanism 2 includes a rotating frame 201. A rotating rod 205 is rotatably connected to the outer surface of the rotating frame 201 via bearings. A support frame 202 is fixedly connected to the outer surface of the rotating rod 205. A slide rail 203 is fixedly connected to the outer surface of the support frame 202. A first rack 204 is slidably connected to the outer surface of the slide rail 203. A rotating rod 211 is rotatably connected to the outer surface of the slide rail 203 via bearings. A first gear 206 is fixedly connected to the outer surface of the rotating rod 211. The first gear 206 meshes with the first rack 204. A mounting frame 207 is fixedly connected to the inner surface of the frame 1. A toothed ring 208 is fixedly connected to the inner surface of the mounting frame 207. A spur gear 209 is fixedly connected to the outer surface of the rotating rod 205. The spur gear 209 meshes with the toothed ring 208. A clamping frame 210 is fixedly connected to the outer surface of the first rack 204.

[0032] The effect is that the first gear 206 meshes with the first rack 204, pushing the clamping frame 210 to further clamp the packaging, ensuring no displacement during subsequent flipping. The spur gear 209 on the outer surface of the rotating rod 205 contacts and meshes with the incomplete toothed ring 208 on the mounting frame 207. Since the incomplete toothed ring 208 is fixed on the mounting frame 207, the spur gear 209, under the constraint of meshing, rotates with the rotating frame 201 while driving the rotating rod 205 to rotate, thereby driving the slide rail 203, clamping frame 210 and packaging to flip synchronously through the support frame 202.

[0033] like Figure 1 - Figure 10As shown, the outer surface of the rotating rod 205 has a groove 5, the inner surface of the groove 5 is slidably connected to a slide plate 6, the outer surface of the slide plate 6 is fixedly connected to a limit plate 7, the outer surface of the mounting frame 207 has an annular groove 8, the annular groove 8 is slidably connected to the limit plate 7, a first spring 9 is fixedly connected between the limit plate 7 and the groove 5, a push rod 10 is fixedly connected to the outer surface of the limit plate 7, a stop block 11 is fixedly connected to the outer surface of the push rod 10, a protrusion 12 is fixedly connected to the inner surface of the mounting frame 207, the protrusion 12 is slidably connected to the stop block 11, the push rod 10 is slidably connected to the rotating rod 205, and a detection mechanism 3 is also provided inside the frame 1. The detection mechanism 3 includes a clamping plate 301, the inner surface of the clamping frame 210 is rotatably connected to a connecting rod 302 through a bearing, the outer surface of the connecting rod 302 is fixedly connected to a first rotating plate 303, the other end of the first rotating plate 303 is rotatably connected to the clamping plate 301 through a bearing, and the inner surface of the clamping frame 210 is rotatably connected to a second rotating plate through a bearing. The second rotating plate 305 and the third rotating plate 304 are rotatably connected to the clamping plate 301 via bearings at their other ends. A limiting shell 13 is fixedly connected to the inner surface of the clamping frame 210. A second rack 14 is slidably connected to the inner surface of the limiting shell 13. A second spring 24 is fixedly connected between the limiting shell 13 and the second rack 14. A second gear 15 is fixedly connected to the outer surface of the connecting rod 302. The second gear 15 meshes with the second rack 14. A baffle 16 is fixedly connected to the outer surface of the mounting bracket 207, and a first elastic element 17 is fixedly connected to the outer surface of the mounting bracket 207. The baffle 16 contacts the first elastic element 17, and the protrusion 12 contacts the stop block 11, so that the push rod 10 drives the limiting plate 7 to move away from the annular groove 8. At this time, the rotating rod 205 can rotate. After the flipping is completed, the protrusion 12 leaves the stop block 11, and with the reset of the first spring 9, the limiting plate 7 is driven to re-enter the interior of the annular groove 8 for limiting, so as to prevent the packaging from shaking after flipping.

[0034] The effect is that during the rotation of the rotating frame 201, the baffle 16 on the clamping frame 210 is first driven to move closer to the first elastic element 17. As the rotating frame 201 continues to rotate, the baffle 16 contacts the first elastic element 17. The reaction force of the first elastic element 17 pushes the baffle 16 to drive the second rack 14 to slide along the limiting shell 13. The second rack 14 meshes with the second gear 15 on the connecting rod 302, driving the connecting rod 302 to rotate around the bearing. The connecting rod 302 is linked with the first rotating plate 303, the second rotating plate 305 and the third rotating plate 304, so that the clamping plate 301 at the top gradually opens until it is fully open. At this time, the bottom clamping plate 301 remains closed and supported. At this time, the infrared detector 21 at the top is activated.

[0035] like Figure 1 - Figure 10As shown, the inner part of the rack 1 is further provided with a flexible mechanism 4, the flexible mechanism 4 comprises a supporting rod 409, the outer surface of the supporting rod 409 is fixedly connected with a first supporting plate 401, the outer surface of the first supporting plate 401 is rotatably connected with a second supporting plate 402 through a bearing, the inner surface of the clamping plate 301 is rotatably connected with a positioning rod 403 through a bearing, the outer surface of the positioning rod 403 is fixedly connected with a third gear 404, the outer surface of the clamping plate 301 is slidably connected with a third rack 405, the third rack 405 is meshedly connected with the third gear 404, the third rack 405 is rotatably connected with the second supporting plate 402 through a bearing, the outer surface of the positioning rod 403 is fixedly connected with a sealing plate 406, the sealing plate 406 is slidably connected with the inner wall of the clamping plate 301, the inner surface of the clamping plate 301 is provided with a plurality of sliding holes 407, the inner surface of the sliding hole 407 is slidably connected with a lifting rod 408, the lower surface of the lifting rod 408 is slidably connected with a flexible piece 410, the supporting rod 409 is rotatably connected with the clamping plate 301 through a bearing, the outer surface of the supporting rod 409 is fixedly connected with a push rod 18, the inner surface of the rack 1 is fixedly connected with a second elastic piece 19, the push rod 18 is in contact with the second elastic piece 19, the supporting rod 409 and the clamping plate 301 are fixedly connected with a torsional spring, the inner surface of the rack 1 is mounted with an infrared detector 21, the inner surface of the rack 1 is fixedly connected with a first motor 22, the output end of the first motor 22 is fixedly connected with a rotating frame 201, the rotating frame 201 is rotatably connected with a mounting frame 207 through a bearing, the outer surface of the sliding rail 203 is mounted with a second motor 23, the output end of the second motor 23 is fixedly connected with a rotating rod 211.

[0036] The effect is that the second motor 23 starts to drive the rotating rod 211 to rotate, the first motor 22 in the rack 1 starts to drive the rotating frame 201 to rotate slowly around the axis of the mounting frame 207, the rotating frame 201 continues to rotate to drive the push rod 18 on the bottom clamping plate 301 to move close to and contact the first group of second elastic members 19, the pushing force of the second elastic members 19 pushes the push rod 18 to overcome the elastic force of the torsional spring, drives the support rod 409 to rotate around the clamping plate 301, when the support rod 409 rotates, the first support plate 401 on the outer surface of the support rod 409 rotates synchronously, and the second support plate 402 is pushed to move through the bearing; the second support plate 402 is rotationally connected with the third rack 405, thereby driving the third rack 405 to slide along the surface of the clamping plate 301, the third rack 405 is engaged with the third gear 404 on the positioning rod 403, drives the positioning rod 403 to rotate around the bearing, and when the positioning rod 403 rotates, the sealing plate 406 fixedly connected therewith rotates along the inner wall of the clamping plate 301; since the inside of the clamping plate 301 is a closed air cavity, the sealing plate 406 will squeeze the gas in the air cavity during the rotating process, so that the internal pressure of the air cavity is increased, the increased air pressure is uniformly applied to the bottom of the lifting rods 408 in the plurality of sliding holes 407, pushes all the lifting rods 408 to move upward along the sliding holes 407, and finally makes the flexible members 410 at the top of the lifting rods 408 uniformly adhere to the bottom surface of the irregularly sealed fruit package; if there is damage on the front of the package, the contact and extrusion of the flexible members 410 and the air cavity pressure jointly act to accelerate the leakage speed of the gas in the package, and obvious airflow disturbance is formed.

[0037] The working principle is that the external mechanical arm picks up the sealed fruit package to be detected and accurately places it between the two clamping plates 301 corresponding to the clamping frame 210 on both sides. After confirming that the package is centered, the mechanical arm withdraws, and the device enters the clamping and reinforcing stage. The second motor 23 on the slide rail 203 starts to drive the rotating rod 211 to rotate. Through the meshing of the first gear 206 and the first rack 204, the clamping frame 210 is further clamped to ensure that there is no displacement during subsequent turning. After clamping and reinforcing, the first motor 22 in the rack 1 starts to drive the rotating frame 201 to slowly rotate around the axis of the mounting frame 207. During the rotation of the rotating frame 201, the baffle 16 on the clamping frame 210 is first driven to approach the first set of first elastic members 17. As the rotating frame 201 continues to rotate, the baffle 16 comes into contact with the first elastic members 17. The reaction force of the first elastic members 17 pushes the baffle 16 to drive the second rack 14 to slide along the limiting shell 13. The second rack 14 meshes with the second gear 15 on the connecting rod 302 to drive the connecting rod 302 to rotate around the bearing. The connecting rod 302 is linked with the first rotating plate 303, the second rotating plate 305, and the third rotating plate 304, causing the top clamping plate 301 to gradually open until it is fully open. At this time, the bottom clamping plate 301 remains closed and supports. At this time, the top infrared detector 21 starts to perform preliminary leak detection on the front of the package to capture whether there is a gas leakage signal. After the top clamping plate 301 is fully open, the rotating frame 201 continues to rotate, driving the push rod 18 on the bottom clamping plate 301 to approach and contact the first set of second elastic members 19. The pushing force of the second elastic members 19 pushes the push rod 18 to overcome the elastic force of the torsional spring, driving the support rod 409 to rotate around the clamping plate 301. When the support rod 409 rotates, the first support plate 401 on its outer surface rotates synchronously, pushing the second support plate 402 to move through the bearing. The second support plate 402 is rotationally connected with the third rack 405, thereby driving the third rack 405 to slide along the surface of the clamping plate 301. The third rack 405 meshes with the third gear 404 on the positioning rod 403 to drive the positioning rod 403 to rotate around the bearing. When the positioning rod 403 rotates, it directly drives the fixedly connected sealing plate 406 to rotate along the inner wall of the clamping plate 301. The sealing plate 406 has an air hole at the bottom of the initial position, and the inside of the clamping plate 301 is a cylindrical chamber. A partition is provided between the positioning rod 403 and the middle chamber. When the sealing plate 406 rotates, external gas enters the air hole near the partition to balance the air pressure, and the original gas in the compression chamber on the other side of the sealing plate 406 is compressed. Since the inside of the clamping plate 301 is a closed air chamber, the sealing plate 406 will squeeze the gas in the air chamber during rotation, causing the internal pressure of the air chamber to rise. The rising air pressure uniformly acts on the bottom of the lifting rods 408 in the multiple sliding holes 407, pushing all the lifting rods 408 to move upward along the sliding holes 407, and finally causing the flexible members 410 at the top of the lifting rods 408 to uniformly adhere to the bottom surface of the irregular sealed fruit package. If there is damage on the front of the package, the contact and compression of the flexible members 410 and the air chamber pressure jointly act on theThe leakage speed of the gas in the package is accelerated, and obvious airflow disturbance is formed. The infrared detector 21 can accurately identify the damage location and degree by capturing the disturbance, and avoid the missed detection problem caused by too small leakage. After the front detection and the extrusion acceleration gas release are completed, the rotating frame 201 continues to rotate, driving the baffle 16 to extrude the first group of first elastic members 17 and the push rod 18 to extrude the first group of second elastic members 19, and then the baffle 16 is separated from the first group of first elastic members 17 and the push rod 18 is separated from the first group of second elastic members 19. At this time, the straight gear 209 on the outer surface of the rotating rod 205 is in contact with and engaged with the incomplete tooth ring 208 on the mounting frame 207. Since the incomplete tooth ring 208 is fixed on the mounting frame 207, the straight gear 209 is engaged and constrained, and rotates with the rotating frame 201, and then drives the rotating rod 205 to rotate, and further drives the sliding rail 203, the clamping frame 210 and the package to rotate synchronously through the support frame 202. Before rotation, the protrusion 12 is in contact with the stop block 11, so that the push rod 10 drives the limiting plate 7 to move away from the annular groove 8. At this time, the rotating rod 205 can rotate. When the rotation is completed, the protrusion 12 is separated from the stop block 11, and the first spring 9 is reset to drive the limiting plate 7 to re-enter the inside of the annular groove 8 for limiting, so as to avoid the shaking of the package after rotation. After the rotation is completed, the straight gear 209 is separated from the incomplete tooth ring 208, and the rotating frame 201 continues to rotate, driving the baffle 16 on the clamping frame 210 after rotation to approach and contact the second group of first elastic members 17. The action of “the first elastic member 17 pushing the baffle 16-the second rack 14 driving the connecting rod 302 to rotate-the top clamping plate 301 being opened” is repeated, so that the back of the package is completely exposed. At the same time, the push rod 18 on the other clamping plate 301 contacts the second group of second elastic members 19, the second elastic member 19 pushes the push rod 18 to trigger the flexible mechanism 4, and the flexible member 410 extrudes the bottom of the package upward again, so as to accelerate the gas leakage speed of the potential damaged part on the back. The top infrared detector 21 is started again to detect the back of the package, so as to completely eliminate the detection blind area. After the back detection is completed, the second motor 23 is reversely rotated to drive the first rack 204 to retreat through the rotating rod 211 and the first gear 206, the clamping frame 210 drives the clamping plate 301 to open, and the package is released. If the detection is qualified, the mechanical arm is grabbed to the qualified product area. If it is unqualified, the mechanical arm is grabbed to the unqualified product area. Finally, the rotating frame 201 and the flexible mechanism 4 are reset under the action of the torsional spring and the first spring 9, the infrared detector 21 is switched to standby mode, and the device waits for the next detection cycle.

[0038] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the present application.
