Description

Technical Field

[0001] This disclosure relates to the field of tire testing technology, and in particular to tire testing components and testing equipment. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity.

[0003] In reality, tires undergo various quality inspections after production, such as checking for defects like cracks on the tire surface, which affect product quality. During actual inspection, not only the outer surface but also the inner wall of the tire needs to be inspected to ensure product quality. In related technologies, the inspection method for the inner wall of the tire often involves directly inserting an image acquisition device into the tire. However, when inspecting tires with small openings, direct insertion can easily damage the image acquisition device by contacting the edge of the tire opening, making inspection impossible.

This disclosure can also be implemented or applied through other different specific embodiments, and various details in this disclosure can be modified or changed according to different viewpoints and application modules without departing from the spirit of this disclosure. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this disclosure can be combined with each other.

[0032] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art to which this disclosure pertains can readily implement it. This disclosure may be embodied in many different forms and is not limited to the embodiments described herein.

[0033] In this disclosure, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic represented in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. Furthermore, the specific features, structures, materials, or characteristics represented may be combined in any suitable manner in any one or a group of embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples represented in this disclosure, as well as the features of those different embodiments or examples.

[0034] Furthermore, the terms "first" and "second" are used for illustrative purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0035] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0036] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0037] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, module, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, modules, items, kinds, and / or groups. The terms “or” and “and / or” as used herein are interpreted as inclusive, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0038] The technical terms used herein are for reference only to specific embodiments and are not intended to limit the scope of this disclosure. The singular form used herein includes the plural form unless the statement explicitly indicates otherwise. The word "comprising" as used in this specification means to specify a particular characteristic, region, integer, step, operation, element, and / or component, and does not exclude the presence or addition of other characteristics, regions, integers, steps, operations, elements, and / or components.

[0039] Although not explicitly defined, all terms, including technical and scientific terms used herein, shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Terms defined in commonly used dictionaries shall be further interpreted as having a meaning consistent with the relevant technical literature and the message of the present disclosure, and shall not be over-interpreted as having an ideal or overly formulaic meaning unless otherwise defined.

[0040] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity.

[0041] In reality, tires undergo various quality inspections after production, such as checking for defects like cracks on the tire surface, which affect product quality. During actual inspection, not only the outer surface but also the inner wall of the tire needs to be inspected to ensure product quality. In related technologies, the inspection method for the inner wall of the tire often involves directly inserting an image acquisition device into the tire. However, when inspecting tires with small openings, direct insertion can easily damage the image acquisition device by contacting the edge of the tire opening, making inspection impossible.

[0042] To address the aforementioned issues, the two opening members in this embodiment of the present disclosure can first open the opening of the tire under test before the image acquisition device enters it, facilitating the image acquisition device's entry into the opening and image acquisition of its inner wall surface. This also prevents the image acquisition device from being damaged by the tire under test due to a small opening.

[0043] Figure 1 The diagram shown is a schematic representation of the detection component in an embodiment of this disclosure. Figure 1 In the example, the tire detection assembly includes a data acquisition component 100 and at least one spreading component 200. The data acquisition component 100 includes at least one image acquisition device 110. At least one of the spreading components 200 is disposed on one side of the data acquisition component 100; the spreading component 200 includes two spreading members 210 that are driven to swing in opposite directions to spread open the opening of the tire under test during the swing, allowing the image acquisition device 110 to be inserted into the tire to acquire images of the inner surface of the tire under test.

[0044] The advantage of the above configuration is that the two opening members 210 can open the opening of the tire under test before the image acquisition device 110 enters the opening, so that the image acquisition device 110 can enter the opening of the tire under test and acquire images of its inner wall surface. At the same time, it can also avoid the situation where the image acquisition device 110 is damaged by the tire under test due to the small opening.

[0045] exist Figure 1 In the example, the acquisition component 100 further includes a second connector 120, and at least one of the spreading components 200 is disposed on the side wall of the second connector 120.

[0046] Figure 2 The diagram shown is a cross-sectional schematic of the detection component in an embodiment of this disclosure. Figure 2 In the example, each of the spreading members 210 includes a connecting tooth 211 and a spreading portion 212 rotatably connected to the connecting tooth 211. The connecting teeth 211 of the two spreading members 210 engage. At least one of the connecting teeth 211 is driven to rotate, causing the two spreading members 210 to swing in opposite directions.

[0047] For example, in Figure 1 In this embodiment, the acquisition component 100 further includes a first driving member 130, which is driven to connect to one of the connecting teeth 211. Those skilled in the art will understand that when the first driving member 130 drives one of the connecting teeth 211 to rotate, that connecting tooth 211 drives the other connecting tooth 211 to rotate, thereby achieving the purpose of the two opening members 210 swinging in opposite directions to open the opening of the tire under test.

[0048] exist Figure 2 In the example, the connecting tooth 211 is provided with a connecting rod, and the supporting part 212 is coaxially rotatably connected to the connecting rod. At least one bearing is provided between the area where the supporting part 212 engages with the connecting rod. When the area where the supporting part 212 engages with the connecting rod is long, two or more bearings may be implemented. For example, the connecting rod is implemented to be detachably connected to the connecting tooth 211. In other embodiments, the connecting rod is fixedly connected to the connecting tooth 211.

[0049] exist Figure 2 In the example, the connecting tooth portion 211 is provided with multiple teeth. These teeth are concentrated in a portion of the connecting tooth portion 211 (e.g., an incomplete gear), and the specific number of teeth is determined by the required opening angle of the two spreading members 210. That is, the larger the required opening angle of the two spreading members 210, the larger the number of teeth on the connecting tooth portion 211, and the larger the range of angles at which the multiple teeth are arranged.

[0050] exist Figure 1 In this example, multiple image acquisition units 110 are implemented. These multiple image acquisition units 110 are spaced apart along the axial direction of the second connector 120, for example, a portion of the second connector 120 is configured in a shape adapted to the cross-sectional shape of the tire, such as a circle. Further exemplarily, the sum of the acquisition areas of the multiple image acquisition units 110 is greater than the cross-sectional length of the tire under test. The advantage of this arrangement is that it avoids a decrease in detection accuracy due to the acquisition area not effectively covering the surface of the tire under test, thereby further improving the detection accuracy of the tire detection assembly. (Here, a call is made first.) Figure 6 ,exist Figure 6 In the example, the dashed lines represent a schematic diagram of the sum of the acquisition areas of the multiple image acquisition devices 110.

[0051] Figure 3 The diagram shows a structure in which the supporting members are implemented as a pair. Figure 4 The diagram shown is a schematic diagram of a single structure of a pair of supporting members. Figure 5The diagram shown is a cross-sectional view of the supporting members being implemented as a pair.

[0052] exist Figure 3 , Figure 4 and Figure 5 In this example, two expansion members 200 are implemented and operate synchronously. The two expansion members 200 are symmetrically disposed on opposite side walls of the second connector 120, and the image acquisition unit 110 is positioned on the second connector 120 between the two expansion members 200.

[0053] For example, the tire detection assembly further includes a drive member 300. The drive member 300 includes a linkage frame 310 and a second drive member 320 for driving the linkage frame 310 to rotate. Each of the expansion members 210 includes a connecting tooth 211 and an expansion portion 212; the connecting teeth 211 of two expansion members 210 in the same expansion member 200 engage; each end of the linkage frame 310 is connected to one of the connecting teeth 211 of the expansion member 200, so that when the linkage frame 310 rotates, the two acquisition members 100 operate synchronously.

[0054] Exemplarily, the linkage frame 310 includes two symmetrically arranged connecting plates 311 and a connecting shaft 312. Each end of the connecting shaft 312 is fixedly connected to one of the connecting plates 311, and the other end of each of the two connecting plates 311 is fixedly connected to a connecting tooth 211. One end of the second driving member 320 is hinged to the second connecting body 120, and the other end is hinged to the connecting shaft 312. Thus, when the second driving member 320 extends or retracts, it drives the two connecting plates 311 to swing via the connecting shaft 312, thereby causing the two opening members 210 of the corresponding opening member 200 to swing in the opposite direction, thereby opening the opening of the tire under test, allowing the area where the image acquisition device 110 is located on the second connecting body 120 to enter the tire under test. Exemplarily, the second driving member 320 is implemented as a hydraulic cylinder or a pneumatic cylinder.

[0055] In other embodiments, the second drive member 320 may also be implemented as a dual-output motor, which is fixedly connected to the second connector 120, with each output end coaxially fixedly connected to one of the connecting teeth 211 on the spreading member 200.

[0056] Figure 6 The diagram shown is a structural schematic of the movement mode of the acquisition component in an embodiment of this disclosure. Figure 6In this example, the acquisition component 100 is located on the second moving unit. The second moving unit includes a first moving component 140 that moves vertically, and a second moving component 150 that moves horizontally. The acquisition component 100 is located on the first moving component 140, the first moving component 140 is located on the second moving component 150, and the second moving component 150 is located at a designated installation position.

[0057] exist Figure 6 In this example, both the first moving member 140 and the second moving member 150 are implemented as electric cylinders. Those skilled in the art will understand that when the tire under test is not at a designated tire inspection station, the acquisition member 100 is located directly above the tire inspection station, and does not contact the tire under test when it is at the tire inspection station. When the tire under test moves to the tire inspection station, the acquisition member 100 is driven by the first moving member 140 until the image acquisition device 110 is aligned with the opening of the tire under test, and then driven by the second moving member 150 until the image acquisition device 110 is inserted into the opening of the tire under test, thereby achieving image acquisition of the inner surface of the tire under test.

[0058] In other embodiments, the first moving member 140 and the second moving member 150 may also be implemented as hydraulic cylinders or pneumatic cylinders.

[0059] Figure 7 The diagram shows the structure of the tire detection component and the clamping component working together. Figure 8 The diagram shown is a structural schematic of a pair of clamping components. Figure 7 and Figure 8 In the example, the tire detection assembly further includes a clamping assembly 400. The clamping assembly 400 includes a symmetrical pair of clamping members 410; the acquisition member 100 and the spreading member 200 are located between the pair of clamping members 410; each clamping member 410 includes at least two linked swing arms 411; when the at least two swing arms 411 are driven to swing, they perform a clamping / releasing action toward the tire to be tested; the outer end of each swing arm 411 is rotatably connected to a clamping roller 412, so that it is clamped onto the tire to be tested along with the pair of clamping members 410 until it is in full contact with the surface of the tire to be tested; wherein, at least one of the clamping rollers 412 is driven to rotate to drive the tire to be tested to rotate.

[0060] exist Figure 8In the example, each of the clamping members 410 further includes a third driving member 413. Exemplarily, the inner end of each swing arm 411 is provided with a driving tooth 4111. The driving teeth 4111 of two swing arms 411 on the same clamping member 410 mesh, and the third driving member 413 is coaxially fixedly connected to the driving tooth 4111 on one of the swing arms 411, so that the two swing arms 411 can be linked when the third driving member 413 is in operation. For example, the driving tooth 4111 is implemented as a plurality of straight teeth or helical teeth.

[0061] exist Figure 8 In the example, each of the clamping members 410 further includes a fourth driving member 414, which is drivenly connected to one of the clamping rollers 412. For example, the fourth driving member 414 is disposed on the top wall of the swing arm 411, and its output end is coaxially and fixedly connected to the clamping roller 412.

[0062] exist Figure 8 In the example, a concave region is formed in the middle of each of the clamping rollers 412. Those skilled in the art will understand that when the clamping roller 412 contacts the tire under test, the upper and lower edges of the tire abut against the larger diameter portions of the clamping roller 412. At this time, the deformation zone provides deformation space to the compressed portion of the tire sidewall. Preferably, the diameters of the top and bottom ends of the clamping roller 412 are the same to further improve the above-mentioned effect.

[0063] In summary, this disclosure provides a tire detection assembly and detection device. The tire detection assembly includes a data acquisition component and at least one spreading component. The data acquisition component includes at least one image acquisition device. At least one of the spreading components is disposed on one side of the data acquisition component; the spreading component includes two spreading members that are driven to swing in opposite directions to spread the opening of the tire under test during the swing, allowing the image acquisition device to be inserted into the tire to acquire images of the inner surface of the tire under test. The detection device is the tire detection assembly. In the embodiments of this disclosure, the two spreading members can first spread the opening of the tire under test before the image acquisition device enters the opening of the tire under test, so as to facilitate the image acquisition device entering the opening of the tire under test and acquiring images of its inner wall surface. At the same time, it can also avoid the situation where the image acquisition device is damaged by the tire under test due to the small opening.

[0064] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
