Description

Technical Field

[0001] This utility model relates to the field of tire appearance inspection, and more specifically, to a device for tire appearance inspection. Background Technology

[0002] With the improvement of living standards, the use of automobiles is increasing, and the demand for tires is constantly increasing. In the tire production process, it is necessary to inspect the appearance of the tires, including checking for surface damage, cracks, scratches, bulges, bubbles, missing rubber, impurities, wear, tread depth, wear uniformity, foreign object embedding, color and gloss, tire markings, and production date. To improve inspection efficiency, cameras are now mostly used to replace human eyes for inspection, such as the tire appearance inspection device disclosed in the authorization announcement number CN205607885U.

[0003] However, the existing technology still has some shortcomings in use. For example, the tire needs to be rotated by a rotating structure during the inspection process. However, the existing technology mainly uses structures such as tire fixing bracket, threaded column, threaded seat, upper hinge support, second support, and hinge base to fix the tire to achieve the purpose of fixing tires of different sizes. Although the adjustment method is relatively simple, it is more troublesome and time-consuming, which reduces the inspection efficiency. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a device for tire appearance inspection, which can improve the inspection efficiency of tires.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A device for tire appearance inspection includes a mounting frame. A positioning plate is fixedly mounted on the inner wall of the mounting frame. A rotating disk is provided on one side of the positioning plate. A circular disk is fixedly connected to one side of the rotating disk. Four arc-shaped fixing plates are equidistantly arranged on the outer side of the circular disk. A fixing mechanism is provided at the connection between the circular disk and the arc-shaped fixing plates. A rotating mechanism is provided at the connection between the positioning plate and the rotating disk. A control panel is mounted on one side of the mounting frame. A camera is mounted on the top of the positioning plate.

[0009] Furthermore, the fixing mechanism includes four telescopic grooves equidistantly formed on the surface of the disc, and four telescopic rods movably fitted into the inner cavities of the four telescopic grooves. One end of each of the four telescopic rods is fixedly connected to one of the four arc-shaped fixing plates, and the other end of each of the four telescopic rods is fixedly connected to a limiting plate. A limiting groove is formed on the inner wall of the telescopic groove relative to the vertical movement trajectory of the limiting plate. A spring is fitted on the surface of each telescopic rod, and both ends of the spring are fixedly connected to the top of the limiting plate and the top of the inner cavity of the limiting groove, respectively.

[0010] Furthermore, a main groove is provided on one side of the disc, and a cylinder is fixedly installed on one side of the disc relative to the main groove. The main groove, the four telescopic grooves and the four limiting grooves are interconnected.

[0011] Furthermore, magnets are embedded in the bottom of the inner cavity of the limiting groove and the bottom of the limiting disk, and the magnetic poles of the two magnets on opposite sides are opposite.

[0012] Furthermore, the surface of the limiting plate is provided with an embedding groove, and a sealing ring is installed inside the embedding groove.

[0013] Furthermore, a first buffer pad is bonded to the top of the arc-shaped fixing plate, and multiple fixing grooves are equidistantly formed on the surface of the first buffer pad.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution utilizes a fixing mechanism. During fixing, air is blown into the telescopic groove by a cylinder. Under the action of air pressure, the limiting plate, telescopic rod and arc-shaped fixing plate are lifted towards the position close to the tire. The fixing is completed by the arc-shaped fixing plate pressing against the inner wall of the tire. The fixing method is simple and solves the problem of low detection efficiency caused by the cumbersome fixing method in the prior art.

[0019] (2) By setting a pressure sensor, this solution can detect the pressure between the arc-shaped fixing plate and the tire, thus avoiding excessive pressure between the arc-shaped fixing plate and the tire, which could cause tire damage. At the same time, by setting a first buffer pad and a second buffer pad, the contact surface between the arc-shaped fixing plate and the tire can be further protected to prevent tire damage.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1:

[0033] Please see Figure 1-5 A device for tire appearance inspection includes a mounting frame 1, a positioning plate 2 fixedly mounted on the inner wall of the mounting frame 1, a rotating plate 3 on one side of the positioning plate 2, a disc 4 fixedly connected to one side of the rotating plate 3, four arc-shaped fixing plates 5 equidistantly arranged on the outer side of the disc 4, a fixing mechanism 6 at the connection between the disc 4 and the arc-shaped fixing plates 5, a rotating mechanism 7 at the connection between the positioning plate 2 and the rotating plate 3, a control panel 8 mounted on one side of the mounting frame 1, and a camera 9 mounted on the top of the positioning plate 2. By setting the arc-shaped fixing plates 5 and the fixing mechanism 6, the tire can be quickly fixed; by setting the rotating mechanism 7, the tire can be rotated; and by setting the camera 9, the tire's appearance can be inspected.

[0034] Preferably, the fixing mechanism 6 includes four telescopic grooves 61 equidistantly opened on the surface of the disc 4, and four telescopic rods 62 movably sleeved in the inner cavity of the four telescopic grooves 61. One end of each of the four telescopic rods 62 is fixedly connected to four arc-shaped fixing plates 5, and the other end of each of the four telescopic rods 62 is fixedly connected to a limiting plate 64. A limiting groove 63 is opened on the inner wall of the telescopic groove 61 relative to the vertical movement trajectory of the limiting plate 64. A spring 65 is sleeved on the surface of the telescopic rod 62, and the two ends of the spring 65 are fixedly connected to the top of the limiting plate 64 and the top of the inner cavity of the limiting groove 63, respectively. A main groove 66 is opened on one side of the disc 4, and a cylinder 67 is fixedly installed on one side of the disc 4 relative to the position of the main groove 66. The main groove 66, the four telescopic grooves 61 and the four limiting grooves 63 are interconnected.

[0035] Specifically, when cylinder 67 is opened, gas enters the four telescopic slots 61 through the main slot 66, lifting the limiting plate 64. This, in turn, causes the telescopic rod 62 and the arc-shaped fixing plate 5 to move synchronously towards the tire. During the lifting process of the limiting plate 64, the spring 65 is compressed. The restoring force of the spring 65 during compression prevents the arc-shaped fixing plate 5 from being lifted too quickly and damaging the tire. It also ensures that the extension of the multiple arc-shaped fixing plates 5 is nearly the same, thus guaranteeing the uniformity of force during tire fixing and preventing damage. After the tire is fixed and inspected, the air pressure is extracted by cylinder 67. At this time, under the action of the restoring force of the spring 65, the arc-shaped fixing plate 5, the telescopic rod 62, and the limiting plate 64 retract, thus preparing for the next fixing.

[0036] Furthermore, magnets 68 are embedded in the bottom of the inner cavity of the limiting groove 63 and the bottom of the limiting plate 64. The magnetic poles of the two magnets 68 are opposite to each other, which can maintain the stability of the limiting plate 64 after it retracts. An embedding groove 69 is opened on the surface of the limiting plate 64, and a sealing ring 610 is installed inside the embedding groove 69. The sealing ring 610 can prevent air leakage in the telescopic groove 61.

[0037] It should also be noted that a first buffer pad 611 is bonded to the top of the arc-shaped fixing plate 5. Multiple fixing grooves 612 are equidistantly formed on the surface of the first buffer pad 611. A pressure sensor 613 is installed at the bottom of the inner cavity of each fixing groove 612. A second buffer pad 614 is bonded to the inner wall of the fixing groove 612 relative to the pressure sensor 613. By setting the pressure sensor 613, the compressive force can be detected when the arc-shaped fixing plate 5 is pressed and fixed against the inner wall of the tire. When the pressure reaches a certain value, the pressure sensor 613 transmits an electrical signal to the control panel 8. The control panel 8 controls the cylinder 67 to stop pressurizing, preventing excessive pressure between the arc-shaped fixing plate 5 and the tire from causing tire damage. Simultaneously, by setting the first buffer pad 611 and the second buffer pad 614, the contact surface between the arc-shaped fixing plate 5 and the tire can be further protected, preventing tire damage.

[0038] Preferably, the rotating mechanism 7 includes a gear ring 71 fixedly installed on one side of the rotating disk 3, a gear 72 meshing with the inner wall of the gear ring 71, a drive shaft 73 fixedly connected to the gear 72, and a servo motor 74 movably fixedly connected to the drive shaft 73. The servo motor 74 is fixedly installed on one side of the positioning disk 2, and the drive shaft 73 and the positioning disk 2 are rotatably connected.

[0039] Specifically, by activating the servo motor 74, the drive shaft 73 and gear 72 rotate synchronously. Since the gear ring 71 and gear 72 are meshed, when the drive shaft 73 rotates, gear 72 and the rotating disk 3 rotate synchronously, thereby causing the tire to rotate. The appearance of the tire can then be inspected using the camera 9 mounted on top of the positioning disk 2.

[0040] The rotating disk 3 has a stepped annular groove 75 on one side. A limiting ring plate 76 is rotatably connected inside the stepped annular groove 75. The limiting ring plate 76 is fixedly installed on the positioning disk 2, which can limit and guide the positioning disk 2 and the rotating disk 3 to ensure the stability of the rotating disk 3 when it rotates.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
