Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and particularly to an electronic label conveying device based on visual detection and deviation correction. Background Art

[0002] As a non-contact automatic identification technology, electronic tags have the advantages of large storage capacity, fast reading speed, and reusability, and are widely used in fields such as logistics, warehousing, retail, and manufacturing. In these application scenarios, electronic tags need to be accurately conveyed and positioned to ensure the accuracy and efficiency of subsequent reading and writing operations and data management. With the continuous development of computer technology and image processing technology, visual detection technology has the advantages of non-contact, high precision, and high speed, and can quickly and accurately detect parameters such as the shape, size, and position of objects. Applying visual detection technology to an electronic tag conveying device can achieve real-time monitoring and deviation correction of electronic tags, improve the positioning accuracy and adaptability of the conveying device, and improve production efficiency and quality.

[0003] When conveying electronic tags, a mechanical transmission system, such as a conveyor belt, is usually used to convey the electronic tags from one position to another. The conveyor belt is usually made of rubber, plastic, or other materials with certain elasticity and friction. When the conveyor belt moves, a frictional force is generated between it and the electronic tag. Since the electronic tag is placed on the conveyor belt, the frictional force of the conveyor belt overcomes the relative motion tendency between the electronic tag and the conveyor belt, causing the electronic tag to move along with the conveyor belt.

[0004] In existing electronic tag conveying devices, if the surface of the conveyor belt is relatively smooth, the frictional force generated between the electronic tag and the conveyor belt will be small, resulting in the electronic tag being prone to sliding on the conveyor belt. Especially when the conveyor belt accelerates, decelerates, or has a slope change, the electronic tag may shift, thus requiring the visual detection and deviation correction mechanism to perform deviation correction work on the electronic tag multiple times. If the surface of the conveyor belt is relatively rough, when the electronic tag falls onto the conveyor belt, at the moment of contact, the conveyor belt will generate an upward supporting force on the electronic tag to prevent it from continuing to fall. The appearance of this supporting force is very rapid, which will cause a sharp change in the motion state of the electronic tag, thus generating an impact. And since the conveyor belt is constantly moving, the electronic tag will immediately be subjected to the frictional force after contacting the conveyor belt, causing the electronic tag to quickly accelerate to the same speed as the conveyor belt. This acceleration process will generate a certain impact force on the electronic tag. At this time, the frictional force generated between the electronic tag and the conveyor belt will be large, thus easily causing wear to the electronic tag. Summary of the Invention

[0005] The purpose of the present invention is to provide an electronic tag conveying device based on visual detection and deviation correction to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: An electronic label conveying device based on visual detection and deviation correction, comprising a support frame; a driving motor is installed on one side of the support frame, a transmission member is installed inside the support frame, the driving motor is in transmission connection with the transmission member, a conveyor belt is connected to the outside of the transmission member, a visual detection and deviation correction mechanism is arranged on one side of the support frame, a fixing block is fixedly connected to the upper surface of the conveyor belt, a base is fixedly connected to the upper surface of the fixing block, a support plate is fixedly connected to the upper surface of the base, an electronic label body is placed on the upper surface of the support plate, the base is connected with an adjusting component, and the adjusting component is used to adjust the friction force generated between the support plate and the electronic label body;

[0007] A limiting component is arranged above the support plate, and the limiting component is used to limit the electronic label body.

[0008] Furthermore, the front view of the support plate is in a "U" - shaped structure, and through - holes are formed inside the support plate, and the through - holes are equidistantly distributed inside the support plate.

[0009] Furthermore, the adjusting component includes a rotating shaft, the rotating shaft penetrates through the base, a first gear is fixedly connected to the lower end of the rotating shaft, a lead screw is fixedly connected to the upper end of the rotating shaft, a slider is threadedly sleeved on the outer surface of the lead screw, a sliding plate is fixedly connected to one side of the slider, and the sliding plate is slidably connected to the support plate.

[0010] Through the above - mentioned technical solution, when the first gear drives the lead screw to rotate through the rotating shaft, the lead screw will drive the sliding plate connected to the slider to move up and down through rotation, and the support plate will guide the movement of the sliding plate, so that the sliding plate moves in a straight line.

[0011] Furthermore, a sealing block is fixedly connected to the upper surface of the sliding plate, and the sealing blocks correspond to the through - holes one by one.

[0012] Furthermore, fixed racks are fixedly connected to the inner side of the support frame, the fixed racks are located on both sides of the conveyor belt, the height of the fixed racks is greater than the height of the first gear, and the height of the fixed racks is less than the height of the fixing block.

[0013] Through the above technical solution, during the process that the conveyor belt drives the base to move through the fixed block, when the base drives the first gear to move to a specified position through the rotating shaft and the first gear is meshed and connected with the fixed rack, due to the continuous movement of the first gear, under the action of the fixed rack, the first gear will rotate. When the first gear is separated from the fixed rack, the first gear will stop rotating. Moreover, when the base connected to the fixed block drives the first gear to the right end of the conveyor belt, when the first gear moves to the specified position again, the first gear will be meshed and connected with the fixed rack located at the right end of the conveyor belt, and the fixed rack located at the left end of the conveyor belt and the fixed rack located at the right end of the conveyor belt are respectively located on both sides of the first gear, which is convenient for the first gear to rotate reversely for resetting after moving to the right end of the conveyor belt.

[0014] Further, the upper end of the rotating shaft is fixedly sleeved with a second gear, one side of the second gear is meshed and connected with a driven rack, the lower surface of the driven rack is fixedly connected with a connecting block, and the connecting block is slidably connected to the base.

[0015] Through the above technical solution, during the process that the first gear drives the second gear to rotate through the rotating shaft, the second gear drives the driven rack to move through rotation. Under the action of the connecting block, it can be ensured that the driven rack is always stably connected to the base and moves linearly on one side of the base.

[0016] Further, one end of the driven rack is fixedly connected with an L-shaped rod, the lower surface of the L-shaped rod is fixedly connected with a support block, and a chute is formed on the upper surface of the base. The support block is slidably connected to the chute.

[0017] Through the above technical solution, the driven rack drives the L-shaped rod to move synchronously, and the support block can guide the movement of the L-shaped rod, so that the L-shaped rod is stably connected to the base through the support block and moves linearly on one side of the base.

[0018] Further, the limiting assembly includes a support rod, the lower end of the support rod is fixedly connected with the L-shaped rod, a guiding groove is formed inside the support rod, a pressing rod is arranged on one side of the support rod, the pressing rod is slidably connected to the guiding groove, and the pressing rods are symmetrically distributed about the longitudinal center line of the support plate.

[0019] Through the above technical solution, the L-shaped rod drives the pressing rod to move towards the center position of the support plate through the support rod, which is convenient for the pressing rod to limit the electronic tag body subsequently.

[0020] Further, grooves are respectively formed on both sides of the sliding plate, through grooves are formed inside the support plate, and the support rod penetrates through the grooves and the through grooves at the same time.

[0021] Through the above technical solution, the support rod penetrates through the groove and the through groove and moves inside the groove and the through groove. By providing the groove and the through groove, it is beneficial to avoid the support rod from colliding with the skateboard and the support plate during movement.

[0022] Furthermore, a fixing plate is fixedly connected to the upper surface of the support plate. A limiting groove is provided inside the fixing plate. The limiting groove is inclined. One end of the pressing rod is fixedly connected with a limiting block, and the limiting block is located inside the limiting groove.

[0023] Through the above technical solution, during the horizontal movement of the pressing rod, the limiting block at the end of the pressing rod will slide inside the limiting groove. Under the limiting action of the limiting groove, the pressing rod will perform a lifting movement while moving horizontally. When the pressing rod moves towards the center position of the support plate, the pressing rod will move downward at the same time, so that the pressing rod presses on the upper surface of the electronic tag body to limit it. When the pressing rod moves towards the outer side position of the support plate, the pressing rod will move upward at the same time, so that the distance between the pressing rod and the support plate gradually increases, facilitating the subsequent electronic tag body to fall onto the support plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] Firstly, in the present invention, the relative position relationship between the support plate and the sealing block can be adjusted through the adjusting component. Before the electronic tag body falls onto the upper surface of the support plate, the sealing block extends upward out of the through hole, so that the electronic tag body is subjected to less frictional force when it falls onto the upper surface of the support plate, which is beneficial to reducing the wear of the electronic tag body during the falling process. When the support plate drives the electronic tag body to be stably conveyed, through the adjustment of the adjusting component, the sealing block is separated from the through hole. Since the upper surface of the support plate is uneven, a large frictional force can ensure that the electronic tag body remains stable on the conveyor belt and is not prone to sliding, facilitating the high-speed conveyance of the electronic tag body or keeping the electronic tag body in an accurate position during the conveyance process.

[0026] Secondly, in the present invention, after the sealing block is separated from the through hole, at this time, only the support plate supports the electronic tag body. Since the support plate has a hollow structure, the through hole can be used as a ventilation port at this time, facilitating the heat dissipation of the electronic tag body during the conveyance process.

[0027] Thirdly, in the present invention, during the operation of the adjustment component, the limiting component is driven to operate through the second gear, the driven rack and the L-shaped rod. When increasing the friction force received by the electronic tag body, during the process of the pressing rod moving towards the center position of the support plate, it moves downward at the same time, so that the pressing rod presses on the upper surface of the electronic tag body to limit it. By limiting the electronic tag body, it is beneficial to avoid the movement of the electronic tag body such as jumping and shaking on the conveyor belt due to vibration and impact, thereby causing position deviation, and thus it is beneficial to greatly reduce the rectification work of the visual inspection rectification mechanism. Similarly, when reducing the friction force received by the electronic tag body, the pressing rod will move towards the outside of the support plate and move upward at the same time, thereby releasing the limitation on the electronic tag body and facilitating the subsequent separation of the electronic tag body from the support plate.

Detailed implementation manners

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] The present invention provides a technical solution: as Figure 1 - Figure 8 shown, an electronic tag conveying device based on visual inspection and deviation correction includes a support frame 1; a driving motor 2 is installed on one side of the support frame 1, a transmission member 3 is installed inside the support frame 1, the driving motor 2 is in transmission connection with the transmission member 3, a conveyor belt 4 is connected to the outside of the transmission member 3, a visual inspection and deviation correction mechanism 5 is arranged on one side of the support frame 1, a fixed block 6 is fixedly connected to the upper surface of the conveyor belt 4, a base 7 is fixedly connected to the upper surface of the fixed block 6, a support plate 8 is fixedly connected to the upper surface of the base 7, an electronic tag body 31 is placed on the upper surface of the support plate 8, and the base 7 is connected with an adjustment assembly;

[0040] It is worth mentioning that: the conveyor belt 4 drives the support plate 8 connected to the base 7 to move through the fixed block 6. The support plate 8 is used to support the electronic tag body 31 and drive the electronic tag body 31 to move together with the conveyor belt 4. By means of the adjustment assembly, the roughness in contact with the bottom of the electronic tag body 31 can be changed, so that the frictional force generated between the electronic tag bodies 31 at different stages of contact between the electronic tag body 31 and the support plate 8 can be changed, thereby ensuring that there is a sufficient frictional force to drive the electronic tag body 31 for conveying, and at the same time, the wear of the electronic tag body 31 can be greatly reduced.

[0041] Please refer to Figures 1 - 5 , the front view of the support plate 8 is in a "U" - shaped structure, and through holes 9 are opened inside the support plate 8, and the through holes 9 are equidistantly distributed inside the support plate 8.

[0042] The function of the support plate 8 is as follows: The support plate 8 is used to support the electronic tag body 31 and drive the electronic tag body 31 to move together with the conveyor belt 4. Moreover, the support plate 8 is made of the same material as the sealing block 17. When only the support plate 8 is used to support the electronic tag body 31 and drive the electronic tag body 31 to move, due to the relatively rough surface of the support plate 8, the frictional force generated between the electronic tag body 31 and the support plate 8 will be relatively large. When the sealing block 17 supports the electronic tag body 31 and drives the electronic tag body 31 to move, the surface of the sealing block 17 is relatively smooth. At this time, the frictional force generated between the electronic tag body 31 and the support plate 8 will be relatively small.

[0043] Please refer to Figures 1 - 6 , the adjusting assembly includes a rotating shaft 10. The rotating shaft 10 penetrates through the base 7. A first gear 11 is fixedly connected to the lower end of the rotating shaft 10. A lead screw 14 is fixedly connected to the upper end of the rotating shaft 10. A slider 15 is threadedly sleeved on the outer surface of the lead screw 14. A slide plate 16 is fixedly connected to one side of the slider 15. The slide plate 16 is slidably connected to the support plate 8. A sealing block 17 is fixedly connected to the upper surface of the slide plate 16. The sealing blocks 17 correspond to the through ports 9 one by one. A fixed rack 13 is fixedly connected to the inner side of the support frame 1. The fixed rack 13 is located on both sides of the conveyor belt 4. The height of the fixed rack 13 is greater than the height of the first gear 11. The height of the fixed rack 13 is less than the height of the fixed block 6.

[0044] The principle of being able to change the magnitude of the frictional force on the electronic tag body 31 during transportation is as follows: When the conveyor belt 4 drives the support plate 8 to move above the conveyor belt 4 through the fixed block 6 and the base 7, and the support plate 8 is located at the leftmost end of the conveyor belt 4, at this time, the sealing block 17 extends out of the through hole 9 and closes the through hole 9. Then the electronic tag body 31 will fall onto the upper surface of the sealing block 17. Compared with a rough plane, since the electronic tag body 31 lands on a flat support plane, the frictional force generated between the electronic tag body 31 and the sealing block 17 is smaller, thereby greatly reducing the wear on the electronic tag body 31. Immediately afterwards, the electronic tag body 31 can be corrected by the vision detection and deviation correction mechanism 5, so that the electronic tag body 31 is located in the exact middle position of the support plate 8. Then, when the conveyor belt 4 drives the support plate 8 connected to the base 7 through the fixed block 6 to move, and the support plate 8 drives the electronic tag body 31 to move together with the conveyor belt 4, when the base 7 drives the first gear 11 to move to a specified position through the rotating shaft 10, and the first gear 11 is engaged with the fixed rack 13, during the process of the base 7 driving the first gear 11 to move linearly through the rotating shaft 10, under the action of the fixed rack 13 located outside the first gear 11, the first gear 11 will rotate. Furthermore, when the first gear 11 drives the lead screw 14 to rotate through the rotating shaft 10, the lead screw 14 will drive the slider 15 threadedly connected thereto to descend through rotation, and the slider 15 will drive the slide plate 16 fixedly connected thereto to descend, so that the slide plate 16 drives the sealing block 17 to move downward, and then the sealing block 17 is separated from the through hole 9. At this time, only the support plate 8 supports the electronic tag body 31 (as Figure 6 shown), and drives the electronic tag body 31 to move. Since the upper surface of the support plate 8 is uneven, the frictional force generated between the electronic tag body 31 and the support plate 8 will increase. The larger frictional force can ensure that the electronic tag body 31 remains stable on the conveyor belt 4 and is not prone to sliding, facilitating the high-speed transportation of the electronic tag body 31 or keeping the electronic tag body 31 in an accurate position during transportation. In addition, the through hole 9 can be used as a ventilation port to facilitate the heat dissipation of the electronic tag body 31 during transportation. When the electronic tag body 31 is about to move to the rightmost end of the conveyor belt 4 and is about to be separated from the support plate 8, at this time, the first gear 11 will be engaged with the fixed rack 13 located at the right end of the support frame 1. Since the fixed rack 13 at the right end is engaged with the inner side of the first gear 11, the lead screw 14 will drive the slide plate 16 connected to the slider 15 to rise through rotation, so that the slide plate 16 drives the sealing block 17 to move upward. The sealing block 17 will extend upward along the through hole 9 and close the through hole 9. At this time, the frictional force generated at the bottom of the electronic tag body 31 will decrease, thereby facilitating the subsequent rapid separation of the electronic tag body 31 from the support plate 8.

[0045] Please refer to Figures 1 - 7, a second gear 12 is fixedly sleeved on the upper end of the rotating shaft 10. One side of the second gear 12 is meshed and connected with a driven rack 18. A connecting block 19 is fixedly connected to the lower surface of the driven rack 18. The connecting block 19 is slidably connected to the base 7. One end of the driven rack 18 is fixedly connected with an L-shaped rod 20. A supporting block 21 is fixedly connected to the lower surface of the L-shaped rod 20. A chute 22 is formed on the upper surface of the base 7. The supporting block 21 is slidably connected to the chute 22.

[0046] The principle of driving the limiting component to operate is as follows: during the process that the first gear 11 drives the rotating shaft 10 to rotate, the rotating shaft 10 simultaneously drives the second gear 12 to rotate. The second gear 12 drives the driven rack 18 to move through rotation. The driven rack 18 drives the L-shaped rod 20 to move. Under the action of the connecting block 19 and the supporting block 21, it can be ensured that the driven rack 18 and the L-shaped rod 20 are always stably connected to the base 7 and perform linear motion on one side of the base 7. The L-shaped rod 20 drives the limiting component to operate during the movement process.

[0047] Please refer to Figures 1 - 8 , a limiting component is arranged above the support plate 8. The limiting component is used to limit the electronic tag body 31. The limiting component includes a support rod 23. The lower end of the support rod 23 is fixedly connected to the L-shaped rod 20. A guiding groove 26 is formed inside the support rod 23. A pressing rod 27 is arranged on one side of the support rod 23. The pressing rod 27 is slidably connected to the guiding groove 26. The pressing rods 27 are symmetrically distributed about the longitudinal center line of the support plate 8. Grooves 24 are respectively formed on both sides of the sliding plate 16. A through groove 25 is formed inside the support plate 8. The support rod 23 penetrates through the grooves 24 and the through groove 25 at the same time. A fixing plate 29 is fixedly connected to the upper surface of the support plate 8. A limiting groove 30 is formed inside the fixing plate 29. The limiting groove 30 is in an inclined state. A limiting block 28 is fixedly connected to one end of the pressing rod 27. The limiting block 28 is located inside the limiting groove 30.

[0048] The principle of being able to limit the electronic tag body 31 is as follows: during the process that the L-shaped rod 20 drives the pressing rod 27 to perform horizontal movement through the support rod 23, the limiting block 28 at the end of the pressing rod 27 will slide inside the limiting groove 30. Under the limiting action of the limiting groove 30, the pressing rod 27 will perform lifting movement while performing horizontal movement. When the pressing rod 27 moves towards the center position of the support plate 8, the pressing rod 27 will simultaneously move downward, so that the pressing rod 27 presses on the upper surface of the electronic tag body 31 to limit it (such as Figure 6As shown, by limiting the electronic tag body 31, it is beneficial to avoid the movement of the electronic tag body 31 on the conveyor belt 4 such as bouncing and shaking due to vibration and impact, which may lead to position deviation, thus greatly reducing the rectification work of the visual inspection rectification mechanism 5. Similarly, when the pressing rod 27 moves towards the outer side of the support plate 8, the pressing rod 27 will move upward at the same time, increasing the distance between the pressing rod 27 and the support plate 8 and releasing the limit on the electronic tag body 31, facilitating the subsequent separation of the electronic tag body 31 from the support plate 8.
