Description

Technical Field

[0001] This utility model relates to the field of tire testing technology, specifically a tire specification testing device. Background Technology

[0002] With the booming development of new energy, the production of automobile tires has also increased significantly. The application of visual inspection technology in tire inspection has significantly improved the accuracy and efficiency of inspection. When inspecting tire specifications, tire specification inspection devices can be used.

[0003] Traditional tire inspection relies primarily on manual methods, which suffer from high labor intensity, susceptibility to subjective factors, and high rates of missed and false detections. To address these shortcomings, a tire specification inspection method, apparatus, electronic device, and readable storage medium disclosed in existing technology (Chinese Patent Application No. CN201911354822.9, Publication Date 2020-05-08) can be referenced. This inspection apparatus determines priorities based on the confidence level of a polygonal target region that includes at least the tire specification, and then checks whether the tire specification matches a preset tire specification according to the priority. This allows for accurate and rapid tire specification inspection. Fully automated review not only improves the accuracy and efficiency of the review process but also saves labor costs, avoiding the drawbacks of high cost, fatigue, and low accuracy associated with manual inspection, thus ensuring the fairness and transparency of the review process.

[0004] Although the above methods can detect tire specifications, there are still some shortcomings in the detection process. The detection requires scanning the tire, but as the conveyor rollers transport the tire, it may shift during the transport process, resulting in some errors during detection.

[0005] Therefore, we proposed that a tire specification testing device can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a tire specification detection device to solve the problem mentioned in the background art that the current tire specification detection devices on the market require scanning the tire during detection, but the tire may shift during the conveying process as it is conveyed by the conveyor roller.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tire specification inspection device, comprising a powered roller conveyor, a light-shielding box installed on one side of the top of the powered roller conveyor; an area scan camera assembly installed inside the light-shielding box, and a barcode scanning assembly fixed on one side of the powered roller conveyor. The barcode scanning assembly includes a guide rail installed on the left side of the powered roller conveyor, and a barcode scanner is fixed at the bottom of the guide rail. The barcode scanner mainly scans vehicles as they are stacked in the air to a designated position. The bottom two sides of the light-shielding box are open to facilitate the entry of car tires. An area scan camera assembly is installed above the light-shielding box. The area scan camera assembly takes pictures of the tires, obtains tire information, and analyzes it using an algorithm to determine whether it is qualified. In addition, a centering clamping assembly is installed below the light-shielding box to limit the tires inside the light-shielding box, facilitating subsequent image processing by the area scan camera assembly.

[0008] As a preferred technical solution of this application, an identification mechanism is installed at the middle position of the power roller line, which can identify the basic information of the tire.

[0009] As a preferred technical solution of this application, the area array camera assembly includes a guide rail fixed to the upper end of the light shield, a slider slidably disposed on the outer side of the guide rail, the slider being driven by an electric push rod, and the area array camera body being fixed below the slider.

[0010] As a preferred technical solution of this application, the centering clamping assembly includes a drive motor fixed at the bottom of the light-shielding box, the output end of the drive motor fixed at the bottom of the rotating disk, connecting rods rotatably connected to the upper two sides of the rotating disk, the other end of the connecting rods rotatably disposed at the bottom of the connecting plate, a clamping rod fixed at the top of the connecting plate, and the inner sides of the other two sets of connecting plates connected by guide telescopic rods.

[0011] As a preferred technical solution of this application, the upper end of the clamping rod is inserted into the roller inside the power roller line, and the two sets of clamping rods form a relative sliding structure with respect to the upper inner side of the connecting plate and the power roller line.

[0012] As a preferred technical solution of this application, the outer side of the clamping rod is attached to the side of the tire, and the connecting plate is slidably positioned at the bottom outer side of the sunshade box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This tire specification detection device adopts modular and standardized commonly used parts, and its universal design makes it easy to produce and assemble. It also accurately detects tire specification information to ensure that it is within the technical standard range. This measure effectively prevents tire quality defects from flowing into the next process, improves production inspection efficiency, and reduces the misjudgment rate caused by long working hours during manual judgment. In addition, the centering clamping component can realize stable limiting treatment of the tire inside the light shield box, which facilitates subsequent information detection and processing. The specific details are as follows.

[0014] 1. A barcode scanning component is installed. The barcode scanner on one side of the component moves on the outside of the guide rail to scan the tire. In addition, the identification mechanism in the middle of the power roller line identifies the basic information of the tire and takes pictures through the area scan camera component. After algorithm analysis, the system makes a judgment and then selects to release or alarm according to the detection standard.

[0015] 2. A centering clamping assembly is provided. When the centering clamping assembly is in operation, the drive motor drives the rotating disk to rotate, which in turn drives the connecting rod to move the connecting plate. The connecting plate moves relative to the guide telescopic rod, which allows the clamping rods on both sides to limit the position of the car tire, facilitating the subsequent image processing of the area scan camera assembly.
