[0003] In related technologies, multiple detection heads are used to clamp the sidewall of the tire, and then the tire is driven to rotate to perform the detection.

[0004] However, because tires come in various widths (e.g., 195mm, 205mm, 215mm, 225mm), after a certain period of use, the sidewall of the inspection head will have multiple wear surfaces of different depths, making it difficult to apply even force when inspecting wider tires.

[0005] Therefore, how to solve the above problems is a problem that urgently needs to be solved by those skilled in the art.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figure 1 As shown, at least one embodiment provides a tire inspection device, including: an inspection platform 1, a limiting mechanism 2, an inspection head 3, a drive mechanism, and a control module.

[0028] Specifically, the testing platform 1 is used to install the limiting mechanism 2 and the drive mechanism, as well as to carry the tire 11 to be tested.

[0029] Specifically, both limiting mechanisms 2 are set on the detection platform 1, and each limiting mechanism 2 is equipped with a pair of detection heads 3; wherein, a detection position 12 for placing the tire 11 is formed between the two limiting mechanisms 2. When the tire 11 needs to be placed, the two limiting mechanisms 2 move in opposite directions. After the tire 11 is placed, the two limiting mechanisms 2 move facing each other so that the four detection heads 3 clamp the tire 11.

[0030] Specifically, such as Figures 2 to 4 As shown, the detection head 3 includes: a plurality of stacked detection plates 31, each detection plate 31 having a negative pressure hole 310 on its lower surface, and a flow sensor being installed inside the negative pressure hole 310; wherein, when the detection head 3 clamps the tire 11, the corresponding number of detection plates 31 are forced to retract according to the thickness of the tire 11; and the negative pressure hole 310 on the detection plate 31 is blocked by the detection plate 31 below when the tire 11 is not placed, and after the tire 11 is placed, the negative pressure hole 310 on the detection plate 31 that is not compressed and is located at the bottom will have two situations: blocked by the tire 11 or not blocked by the tire 11.

[0031] In this embodiment, by setting multiple stacked detection plates 31, when the detection head 3 clamps the tire 11, the corresponding number of detection plates 31 are made to abut against the tire 11 and move back according to the different thicknesses of the tire 11, thereby avoiding the detection plates 31 from not contacting the tire 11 due to wear; at the same time, after the tire 11 is clamped, the perpendicularity of the tire 11 is judged according to the flow data obtained by the flow sensor.

[0032] In some embodiments, the control module is electrically connected to each flow sensor.

[0033] In this embodiment, the control module may be, but is not limited to, a PLC; when the perpendicularity of the tire 11 is qualified, all negative pressure holes 310 will be blocked; when the perpendicularity of the tire 11 is unqualified, at least one negative pressure hole 310 will not be blocked, that is, when the flow data obtained by any flow sensor exceeds the threshold, it is determined that the perpendicularity of the tire 11 is unqualified.

[0034] In some embodiments, the tire detection device further includes a drive mechanism; wherein the drive mechanism is not shown in the figure.

[0035] In this embodiment, once the tire 11 is clamped and its perpendicularity is within acceptable limits, the drive mechanism is used to drive the tire 11 within the detection position 12 to rotate.

[0036] like Figure 1 As shown, in some embodiments, the limiting mechanism 2 includes a mounting bracket 21 and a cylinder 22.

[0037] Specifically, the testing platform 1 is provided with a slide rail 13, and the lower surface of the mounting bracket 21 is provided with a slide groove 211; the cylinder 22 is provided on the testing platform 1 and connected to the mounting bracket 21 through a connector.

[0038] In this embodiment, the cylinder 22 is electrically connected to the control module, which is configured to control the cylinder 22 to drive the mounting bracket 21 to slide on the slide rail 13.

[0039] like Figure 3 As shown, in some embodiments, the detection sheet 31 includes a plurality of detection sub-sheets 311; wherein each detection sub-sheet 311 is uniformly distributed along the circumference.

[0040] In this embodiment, a gap is left between each detection sub-piece 311 so that the detection sub-piece 311 can retract when subjected to force.

[0041] like Figure 5 , Figure 6 As shown, in some embodiments, the detection head 3 further includes: a mounting ring 33 and a mounting post 34; wherein a connecting rod 312 is provided on the inner side of the detection sub-piece 311; the connecting rod 312 is arranged radially along the mounting ring 33, passes through the mounting ring 33 and extends into the mounting post 34.

[0042] In this embodiment, the detection sub-piece 311 is located outside the mounting ring 33, and the connecting rod 312 passes through the mounting ring 33 and extends into the mounting post 34, thereby guiding the movement of the detection sub-piece 311.

[0043] like Figure 6 As shown, in some embodiments, the detection head 3 further includes a pair of mounting plates 35.

[0044] Specifically, the mounting ring 33 and the mounting post 34 are located between the two mounting plates 35, and both ends are connected to the corresponding mounting plates 35 to form a stable frame, and each connecting rod 312 is inserted into the frame.

[0045] like Figure 5 , Figure 6 As shown, in some embodiments, the connecting rod 312 is provided with an anti-detachment part 313 and a return spring 314; wherein the anti-detachment part 313 and the return spring 314 are both located between the mounting ring 33 and the mounting post 34; one end of the return spring 314 abuts against the anti-detachment part 313 and the other end abuts against the mounting post 34.

[0046] In this embodiment, the anti-detachment part 313 is located between the mounting ring 33 and the mounting post 34. The anti-detachment part 313 abuts against the inner wall of the mounting ring 33, thereby preventing the detection sub-piece 311 from detaching from the mounting.

[0047] like Figure 5 As shown, in some embodiments, each detection sub-piece 311 has a negative pressure hole 310 on its lower surface.

[0048] In this embodiment, there is a chamber between the mounting ring 33 and the mounting post 34, and the other end of the negative pressure hole 310 extends to the anti-detachment part 313. By connecting the negative pressure generator with the chamber between the mounting ring 33 and the mounting post 34, gas can be drawn in when the negative pressure hole 310 is not blocked, that is, the flow sensor can collect flow data.

[0049] like Figure 6 As shown, in some embodiments, the mounting post 34 has a plurality of chambers 341 for containing maintenance oil arranged from top to bottom; each connecting rod 312 in a detection piece 31 extends into the corresponding chamber 341; an oil outlet hole 315 is provided in the connecting rod 312, one end of the oil outlet hole 315 is located on the inner end face of the connecting rod 312, and the other end is located on the side wall of the detection piece 311; wherein, the detection piece 311 is adapted to apply maintenance oil to the tire 11 through the oil outlet hole 315 when under pressure.

[0050] In this embodiment, when the detection sub-piece 311 is subjected to force, the connecting rod 312 will squeeze the chamber 341, thereby causing the maintenance oil in the chamber 341 to be squeezed out and coated on the surface of the tire 11.

[0051] like Figure 6 As shown, in some embodiments, an oil replenishment channel 342 is provided inside the mounting column 34; wherein the oil replenishment channel 342 is connected to each chamber 341.

[0052] In this embodiment, the oil replenishment channel 342 is connected to an oil replenishment mechanism (not shown in the figure). The oil replenishment mechanism periodically replenishes oil into the chamber 341 to ensure that the maintenance oil in the chamber 341 is maintained at a capacity that can be squeezed out.

[0053] like Figure 5 As shown, in some embodiments, the lower surface of the detection sub-piece 311 is provided with a chamfer 316.

[0054] In this embodiment, the presence of chamfer 316 facilitates clamping the tire 11.

[0055] At least one embodiment also provides a method for operating a tire inspection device, comprising: placing a tire 11 to be inspected into an inspection position 12; clamping the tire 11 in the inspection position 12 by an inspection head 3 on a limiting mechanism 2; when the inspection head 3 clamps the tire 11, causing a corresponding number of inspection pieces 31 to retract according to the thickness of the tire 11; when the inspection head 3 clamps the tire 11, controlling a corresponding flow sensor through a control module to acquire flow data in the negative pressure hole 310 on the inspection piece 31, and determining that the perpendicularity of the tire 11 is unqualified when the flow data acquired by any flow sensor exceeds a threshold.

[0056] For details on the specific structure and implementation process of the tire testing device, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0057] In some embodiments, during the rotation of the tire 11, maintenance oil is applied to the tire 11 by the detection head 3.

[0058] In summary, this tire inspection device and its working method, by setting up multiple stacked inspection pieces 31, ensure that when the inspection head 3 clamps the tire 11, the corresponding number of inspection pieces 31 abut against the tire 11 and move back according to the different thicknesses of the tire 11, thereby avoiding the inspection pieces 31 from not contacting the tire 11 due to wear; at the same time, after the tire 11 is clamped, the perpendicularity of the tire 11 is judged based on the flow data obtained by the flow sensor.
