Description

Technical Field

[0001] The utility model belongs to the technical field of tire detection, and in particular relates to a first tire character detection device. Background Art

[0002] In the tire manufacturing industry, the surfaces of the upper and lower sidewalls of vulcanized tires have thousands of characters. However, various conditions may arise during the production process, resulting in surface character errors, wear, and other problems on the vulcanized tires. To address this, during the production process of the first mold finalization, the first tire after vulcanization relies on manual comparison to confirm whether the text and patterns on the upper and lower sidewalls are incorrect and whether there is any wear. Although this method can effectively prevent the same errors from occurring in an entire batch of products, it has obvious disadvantages. On the one hand, manual inspection is extremely time-consuming, and the character area on the tire sidewall indicates important information such as the tire specifications, load index, and speed level. The large number of characters makes the work extremely intensive. On the other hand, if characters are omitted, overprinted, or misprinted during the production of the first mold finalization, defective and waste products will be produced, causing significant economic losses to the tire manufacturer.

[0036] See attached Figures 1 to 6 , gives a schematic embodiment of the first-born character detection device proposed in the utility model, which includes a device body 1, a platform 2, a positioning device 3, a robotic arm 4, a barcode scanner 6 and a control cabinet 7.

[0037] The platform 2 is provided on the equipment body 1, and a positioning hole 21 is provided on the platform 2, and the platform 2 is used to support the tire. The positioning device 3 is provided on the platform 2, and the positioning device 3 passes through the positioning hole 21 to position the tire. The robotic arm 4 is provided on the equipment body 1, and the robotic arm 4 is provided with an identification camera 5, and the identification camera 5 is used to identify the character information on the side surface of the tire. The barcode scanner 6 is provided on the equipment body 1, and the barcode scanner 6 is used to scan and obtain tire specification information. The control cabinet 7 is provided on the equipment body 1, and a control system 8 is provided in the control cabinet 7. The control system 8 connects the identification camera 5 and the barcode scanner 6 to receive the character information and tire specification information on the side surface of the tire and determine whether the tire is qualified. In order to solve the above problems, the first tire character detection equipment can quickly and efficiently identify the character information on the side surface of the tire, specifically including the character information on the upper sidewall and lower sidewall surfaces of the tire.

[0038] Operators move the first batch of vulcanized tires from each production line onto platform 2. They then use a barcode scanner 6 to scan the barcode on the tire surface to obtain tire specifications. Positioning device 3 positions the tire at the center of platform 2. Driven by robotic arm 4, recognition camera 5 moves to a designated work area and automatically focuses to identify the character information on the tire's sidewall. After identifying the character information on the tire's sidewall, operators manually flip the tire over and perform character information recognition on the sidewall. After recognition is complete, control system 8 receives the character information and tire specifications and determines whether the tire is qualified.

[0039] To enhance tire placement flexibility, in this embodiment, ball bearings 22 are provided on the side of platform 2 that contacts the tire. These ball bearings 22 enable the tire to move flexibly in multiple directions on platform 2. Furthermore, they shift the friction between the tire and platform 2 from sliding to rolling friction. This low-friction design significantly reduces labor intensity, improves work efficiency, reduces wear and tear, protects the tire surface, extends the service life of platform 2, and reduces maintenance costs.

[0040] In order to improve the detection accuracy, in this embodiment, the recognition camera 5 is selected as a 3D recognition camera. The 3D recognition camera can accurately recognize the character information on the side surface of the tire and has high detection accuracy.

[0041] To flexibly and precisely control the position of the recognition camera 5, in this embodiment, the robotic arm 4 is a six-degree-of-freedom robotic arm. This six-degree-of-freedom robotic arm can achieve nearly any position and posture within the designated working area of ​​the first-tire character detection device, making the first-tire character detection device applicable to tires of different specifications and sizes.

[0042] Positioning device 3 includes a track 31, a slider 32, and a cylindrical roller 33. Track 31 is provided on platform 2, and slider 32 is mounted on track 31 to move along track 31. Cylindrical roller 33 is mounted on slider 32 and passes through positioning hole 21 to position the tire. To position the tire at the center of platform 2, in this embodiment, platform 2 is provided with four positioning holes 21, and four tracks 31, slider 32, and cylindrical roller 33 are each provided. Together, they achieve tire positioning.

[0043] To improve the automation of positioning, in this embodiment, positioning device 3 further includes a first cylinder 34, a pulley 35, and a belt 36 wound around pulley 35. Pulley 35 is located on platform 2, and belt 36 is connected to slider 32. First cylinder 34 is connected to belt 36 to drive belt 36, thereby driving slider 32. To enable the four cylindrical rollers 33 to move the same distance simultaneously for positioning, in this embodiment, multiple pulleys 35, one first cylinder 34, and one belt 36 are provided.

[0044] To ensure stable positioning of the tire, in this embodiment, the positioning device 3 further includes a second cylinder 37, which is connected to the cylindrical rollers 33 to raise or lower the cylindrical rollers 33. When the equipment is testing, the second cylinder 37 drives the four cylindrical rollers 33 to rise, stably positioning the tire at the center of the platform 2. After the testing is completed, the second cylinder 37 drives the four cylindrical rollers 33 to lower.

[0045] The character information on the tire's side surface is located around the tire's side surface. To facilitate the detection process, in this embodiment, the first-tire character detection equipment also includes a rotating device 9. The rotating device 9 includes a fixed plate 91, a slewing bearing 92 provided on the fixed plate 91, and a servo motor 93. The fixed plate 91 is fixed to the device body 1. The slewing bearing 92 is connected to the platform 2. The servo motor 93 is connected to the slewing bearing 92 to drive the support platform 2 to rotate. Driven by the robotic arm 4, the recognition camera 5 moves to the designated working area and automatically focuses to identify the character information on the tire's side surface. At this time, the rotating device 9 begins to rotate the platform 2. After the platform 2 drives the tire to rotate one circle, the recognition camera 5 completes the recognition.

[0046] To enable operators to intuitively and in real time determine whether a tire is acceptable, in this embodiment, the control system 8 also includes an alarm light 81 and a display screen 82. The alarm light 81 is located on the equipment body 1 and is used to output a pass signal or an error signal based on the control system 8's determination. In some embodiments, the pass signal can be a green light on the alarm light 81, and the error signal can be a red light on the alarm light 81. The display screen 82 is located on the surface of the control cabinet 7 and is used to display the character information received by the control system 8 on the tire side surface, tire specifications, and the tire's acceptance determination result. Based on this data, operators can optimize and improve the production process to improve product quality.
