Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing and processing technology, and specifically relates to a tire barcode reading device. Background Technology

[0002] In tire manufacturing, quality traceability, and logistics management, barcode recognition technology is widely used for the automatic collection and tracking of product information. Traditional manual scanning methods are inefficient, labor-intensive, and difficult to read stably when tires are stacked or rolling, easily leading to missed scans and misreads, which cannot meet the requirements of modern production lines for continuous operation and real-time data.

[0003] Many existing automatic barcode readers employ fixed scanning or simple lifting structures, resulting in poor adaptability and incompatibility with tires of different diameters or heights, thus limiting the device's versatility. Furthermore, if the tire is not effectively secured during reading, it is prone to rolling or vibration due to its own weight, causing positional shifts and affecting the success rate of barcode reading. While some devices have clamping structures, these are often rigid clamps or manually adjustable, lacking adaptive buffering capabilities, which can easily damage the tire surface and provide insufficient clamping stability.

[0004] Furthermore, the drive mechanism design in existing equipment is relatively simple, often employing direct electrofusion connections or cylinder push-pull mechanisms, resulting in unstable lifting or clamping movements and a tendency for wear or jamming over long-term operation. For multi-station integrated production lines, the equipment must also possess good responsiveness and coordination capabilities, while traditional structures are insufficient in terms of automated linkage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] Please see Figure 1-4 The present invention provides the following technical solution:

[0031] A tire barcode reading device, comprising:

[0032] Lower frame 1;

[0033] Side frame 2 is fixedly connected to the upper end of the lower frame 1;

[0034] Top plate 3 is fixedly connected to the upper end of side frame 2;

[0035] The first lead screw 4 is connected to the lower end of the top plate 3, and the circumferential surface of the first lead screw 4 is connected to the first lead screw nut 5.

[0036] Barcode reading device 6 is connected to the lower end of the first lead screw nut 5;

[0037] A clamping mechanism is provided at the upper end of the lower frame 1 to clamp the tire;

[0038] Tire 31 is connected to the upper end of the clamping mechanism.

[0039] In a specific embodiment of this utility model, when the lower frame 1 is fixedly installed on a workbench or the ground, the side frame 2 is vertically connected to its upper end, providing overall structural support; the top plate 3 is fixed to the top of the side frame 2 for installing the first lead screw 4; the first lead screw 4 is vertically arranged, and the first lead screw nut 5 on it can move up and down axially when the lead screw rotates; when it is necessary to adjust the barcode reading height, the drive device drives the first lead screw 4 to rotate, so that the first lead screw nut 5 drives the barcode reading device 6 to rise and fall to adapt to the barcode position of different specifications of tires 31; the clamping mechanism is installed on the lower frame 1. The end is used to stably clamp the tire 31 to prevent it from rolling or shifting during the reading process. After the tire 31 is clamped and positioned, the barcode reading device 6 descends to the area where the barcode is located on the tire sidewall for automatic scanning and recognition. The barcode reading device 6 is an existing technology and can use mature components such as laser scanners or industrial cameras to collect barcode information on the tire and transmit it to the control system. The device, through an adjustable lifting structure and stable clamping, enables fast and reliable reading of barcodes on tires of different sizes and is suitable for automated scenarios such as tire production, testing, and warehousing.

[0040] Please refer to the details. Figure 1-4 The clamping mechanism includes a rectangular platform 11, a fixed base 14, a second lead screw 15, a second lead screw nut 16, a rack 18, and a clamping assembly. The rectangular platform 11 is fixedly connected to the upper end of the lower frame 1, the fixed base 14 is fixedly connected to the upper end of the rectangular platform 11, the second lead screw 15 is connected to the side end of the fixed base 14, the second lead screw nut 16 is connected to the second lead screw 15, the rack 18 is connected to the upper end of the second lead screw nut 16, and the clamping assembly is disposed at the upper end of the second lead screw nut 16 to achieve tire clamping.

[0041] In this embodiment: when the tire 31 is placed on the rectangular platform 11, the driving device drives the second lead screw 15 to rotate, the second lead screw nut 16 moves axially along the second lead screw 15, the rack 18 moves synchronously with the second lead screw nut 16, and the rack 18 meshes with the gear in the clamping assembly, transmitting linear motion to the clamping assembly. Driven by the rack 18, the clamping assembly moves the clamping blocks 17 on both sides inward synchronously, clamping and positioning the rim of the tire 31 to ensure stability during barcode reading and prevent reading failure due to shaking or displacement. The fixed seat 14 provides a stable mounting support for the second lead screw 15, ensuring smooth and reliable transmission. When the tire needs to be released, the second lead screw 15 rotates in the opposite direction, driving the clamping assembly to exit synchronously, completing the unloading. This clamping mechanism achieves synchronization and reliability of clamping actions through the linkage structure of the second lead screw 15 and rack 18, adapting to the clamping requirements of tires of different diameters and improving the stability and efficiency of barcode reading.

[0042] Please refer to the details. Figure 1-4 The clamping assembly includes a rectangular plate 26, a rotating rod 19, a gear 20, a sliding frame 21, a sliding rod 22, a disc 23, an arc-shaped groove 24, and a protrusion 25. The rectangular plate 26 is connected to the upper end of the rectangular platform 11. The rotating rod 19 is rotatably connected to the side end of the rectangular plate 26. The gear 20 is fixedly connected to the lower end of the rotating rod 19. The sliding frame 21 is connected to the upper end of the rectangular plate 26. The sliding rod 22 is slidably connected inside the sliding frame 21. The disc 23 is fixedly connected to the upper end of the rotating rod 19. The arc-shaped groove 24 is opened at the upper end of the disc 23. The protrusion 25 is fixedly connected to the upper end of the sliding rod 22 and is slidably connected to the arc-shaped groove 24.

[0043] In this embodiment: when the rack 18 moves with the second lead screw nut 16, it drives the gear 20 meshing with it to rotate. The gear 20 is fixed to the lower end of the rotating rod 19 and rotates accordingly. The upper end of the rotating rod 19 is fixedly connected to the disc 23. The arc groove 24 on the disc 23 slides and engages with the protrusion 25 at the upper end of the slide rod 22. The slide rod 22 is slidably connected to the slide frame 21. When the disc 23 rotates, the arc groove 24 pushes the protrusion 25 to move linearly back and forth along the slide frame 21, thereby driving the slide rod 22 to move up and down. The slide rod 22 is connected to the clamping block 17 to clamp or release the rim of the tire 31. This structure transmits the rotational motion to the rotating rod 19 through the gear 20 and the rack 18, and then through the cam engagement of the disc 23 and the arc groove 24, it is converted into the linear motion of the slide rod 22, realizing a stable and reliable clamping action with uniform clamping force, which can meet the positioning requirements of tires of different specifications.

[0044] Please refer to the details. Figure 1-4 A connecting rod 27 is fixedly connected to the side end of the slide rod 22, and a cylinder 28 is fixedly connected to the upper end of the connecting rod 27. A spring 30 is sleeved on the circumferential surface of the cylinder 28, and an arc-shaped clamp 29 is fixedly connected to the upper end of the cylinder 28. The arc-shaped clamp 29 is matched with the tire 31.

[0045] In this embodiment: when the slide bar 22 moves upward under the drive of the clamping assembly, it drives the connecting rod 27 connected to its side end to move synchronously, and the cylinder 28 at the upper end of the connecting rod 27 rises accordingly; an arc-shaped clamping plate 29 is installed at the upper end of the cylinder 28, the shape of which matches the outer contour of the tire 31. When the piston rod of the cylinder 28 extends, it pushes the arc-shaped clamping plate 29 to move closer to the tire sidewall to achieve auxiliary clamping; the spring 30 is sleeved on the outer periphery of the cylinder 28 to provide buffering and adaptive clamping force, absorb impact during clamping, avoid damage to the tire surface, and compensate for slight differences in tire size; after the main clamping mechanism completes the initial positioning through the slide bar 22, the cylinder 28 drives the arc-shaped clamping plate 29 to further fit the tire 31, enhance the overall clamping stability, and prevent the tire from shaking during barcode reading; this structure combines mechanical linkage and pneumatic auxiliary clamping to improve the reliability and adaptability of clamping, and ensure accurate and efficient barcode reading.

[0047] In this embodiment: meshing transmission transmits power to the first lead screw 4, causing it to rotate; the rotation of the first lead screw 4 drives the first lead screw nut 5 to move up and down axially, thereby achieving smooth lifting and lowering of the barcode reading device 6 to adapt to the barcode position of tires 31 of different specifications; when clamping operation is required, the second motor 17 starts, and its output end drives the second lead screw 15 to rotate, which drives the rack 18 to make linear motion through the second lead screw nut 16, thereby driving the gear 20 and the rotating rod 19 in the clamping assembly to rotate, which is converted into linear motion of the slide rod 22 through the arc groove 24 and the protrusion 25 on the disc 23, and finally drives the cylinder 28 and the arc clamping plate 29 through the connecting rod 27 to complete the clamping and positioning of the tire 31; the device achieves stable lifting and lowering of the barcode reading device through sprocket and chain transmission, and cooperates with the motor to drive the lead screw to control the clamping action, realizing automated and reliable tire clamping and barcode recognition operation.

[0048] Please refer to the details. Figure 1-4 A slide 12 is fixedly connected to the upper end of the rectangular platform 11, and a slider 13 is slidably connected to the upper end of the slide 12. The slider 13 is connected to the rectangular plate 26, and the rack 18 meshes with the gear 20.

[0049] In this embodiment: when the second motor 17 drives the second lead screw 15 to rotate, it drives the second lead screw nut 16 to move axially, thereby pushing the rack 18 to move synchronously; the rack 18 meshes with the gear 20, converting linear motion into rotational motion of the gear 20, which is fixed to the lower end of the rotating rod 19 and drives it to rotate; the disc 23 at the upper end of the rotating rod 19 rotates accordingly, and the arc groove 24 on it pushes the protrusion 25 at the upper end of the slide rod 22 to make linear reciprocating motion along the slide frame 21, thereby realizing the clamping action; the rectangular plate 26 is slidably connected to the slide table 12 through the slider 13, so that the entire clamping assembly maintains stable guidance during the clamping process, avoiding jamming or deflection due to uneven force; the cooperation between the slide table 12 and the slider 13 provides reliable lateral support and motion guidance for the clamping mechanism, ensuring that the clamping actions on both sides are synchronous and stable; this structure achieves precise and reliable clamping of the tire 31 through lead screw-rack-gear linkage drive, combined with slide table guidance, improving the stability and automation level of the barcode reading process.

[0050] The working principle and usage process of this utility model are as follows: After the equipment is powered on and started, when the operator places the tire 31 to be identified at the center of the rectangular platform 11, when the control system issues a clamping command, when the second motor 17 starts, when its output end drives the second lead screw 15 to rotate, when the second lead screw nut 16 moves along the lead screw axis, when the rack 18 moves synchronously with the second lead screw nut 16, when the rack 18 meshes with the gear 20, when the gear 20 drives the rotating rod 19 to rotate, when the disc 23 at the upper end of the rotating rod 19 rotates accordingly, when the arc groove 24 on the disc 23 pushes the protrusion 25 to slide along the slide frame 21, when the slide rod 22 moves upward under the action of the protrusion 25, when the slide rod 22 drives the cylinder 28 to rise through the connecting rod 27, when the piston rod of the cylinder 28 extends, when the arc clamp 29 completely adheres to the side wall of the tire 31. The system is clamped and positioned. Once the clamping is stable, the first motor 8 starts, and the second sprocket 9 at its output end drives the first sprocket 7 to rotate via the chain 10. The first lead screw 4 rotates accordingly, and the first lead screw nut 5 drives the barcode reading device 6 to descend axially. The barcode reading device 6 reaches the height of the barcode on the sidewall of the tire 31. The barcode reading device 6 starts automatically, scanning the barcode on the tire 31 and transmitting the recognition result to the control system. After the barcode reading is completed, the first motor 8 reverses, the barcode reading device 6 rises and resets, the piston rod of the cylinder 28 retracts, the clamping assembly releases the tire 31, the second motor 17 reverses, the clamping mechanism returns to its initial position, the operator removes the tire 31, and the system prepares to enter the next work cycle, thus realizing the automated reading of the tire barcode.
