[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0036] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] like Figures 1 to 3 As shown, at least one embodiment provides a tire noise reduction sponge rebound time detection device, which includes: a detection box 1, on which a top cover 11 is passed, and a noise reduction sponge 6 that can support the top cover 11 is arranged on the detection box 1; an endless conveyor belt 2, on which a starting position 21, a pressure position 22, and a sorting position 23 are sequentially arranged; a pressing mechanism 3, located above the pressure position 22 of the endless conveyor belt 2, which can be but not limited to a cylinder; a sorting mechanism 4, located above the sorting position 23 of the endless conveyor belt 2; and a control module, which is electrically connected to the pressing mechanism 3 and the endless conveyor belt 2, and is configured to control the endless conveyor belt 2 to drive the detection box 1 to move to the pressure position 22, then control the pressing mechanism 3 to press down the top cover 11 of the detection box 1 to a first preset height to compress the noise reduction sponge, and finally control the endless conveyor belt 2 to transport the compressed noise reduction sponge from the pressure position 22 to the sorting position 23 within a unit time; wherein the sorting mechanism 4 sorts the noise reduction sponge according to the rebound height of the top cover 11 driven by the noise reduction sponge within a unit time.

[0038] In this embodiment, during detection, the noise reduction sponge 6 is placed in the detection box 1 and covered with the top cover 11, and then the detection box 1 with the noise reduction sponge 6 is placed on the circular conveyor belt 2, and finally the circular conveyor belt 2 is controlled to rotate one circle, so that the noise reduction sponge 6 passes through the starting position 21, the pressure position 22, and the sorting position 23 in sequence; when the noise reduction sponge 6 moves to the pressure position 22, the control module controls the pressing mechanism 3 to press the top cover 11 down to the first preset height to compress the noise reduction sponge; the compressed noise reduction sponge continues to be conveyed by the circular conveyor belt 2 to move from the pressure position 22 to the sorting position 23. During the movement, the noise reduction sponge is gradually Gradually restore the deformation to drive the top cover 11 to rise in height; wherein, the time for the annular conveyor belt 2 to drive the noise reduction sponge 6 to move from the pressure position 22 to the sorting position 23 is set as a unit time. Within the unit time, the height to which the qualified noise reduction sponge 6 drives the top cover 11 to rise is fixed. If the height to which the noise reduction sponge 6 drives the top cover 11 to rise in the unit time is too high, it indicates that the rebound is too fast. If the height to which the noise reduction sponge 6 drives the top cover 11 to rise in the unit time is too low, it indicates that the rebound is too slow. Therefore, the sorting mechanism 4 can sort the noise reduction sponge 6 according to the height to which the top cover 11 is lifted to eliminate unqualified noise reduction sponges 6.

[0039] like Figures 4 to 7 As shown, in some embodiments, the sorting mechanism 4 includes two symmetrically arranged guide components; the two guide components are respectively used to guide the corresponding ends of the top cover 11, and both include: a guide frame 41, which is located above the endless conveyor belt 2, and a downward pressing slope 411 is provided on the lower surface; a guide block 42, which is located above the guide frame 41, and a channel 43 is left between the guide frame 41, and a lifting slope 421 is provided on the upper surface of the guide block 42; wherein when the rebound rate of the noise reduction sponge is qualified, the top cover 11 rebounds to the height of the channel 43 and passes through the channel 43; when the rebound rate of the noise reduction sponge is too fast, the top cover 11 rebounds to the height of the lifting slope 421, and is lifted off the base 11 by the lifting of the lifting slope 421; when the rebound rate of the noise reduction sponge is too slow, the top cover 11 rebounds to the height of the downward pressing slope 411, and is pressed down to a second preset height by the downward pressing slope 411 to squeeze the noise reduction sponge.

[0040] In this embodiment, the height of the channel 43 between the guide frame 41 and the guide block 42 is the height at which the qualified noise reduction sponge 6 drives the top cover 11 to be lifted per unit time; the height of the lifting slope 421 is the height at which the noise reduction sponge 6 that rebounds too quickly drives the top cover 11 to be lifted per unit time; the height of the downward pressing slope 411 is the height at which the noise reduction sponge 6 that rebounds too slowly drives the top cover 11 to be lifted per unit time.

[0041] like Figure 5 As shown, specifically, when the noise reduction sponge 6 to be detected moves to the sorting position 23 , if the height of the top cover 11 is at the height of the channel 43 , the top cover 11 will move along the channel 43 driven by the endless conveyor belt 2 until it passes through the channel 43 .

[0042] like Figure 6 As shown, specifically, when the noise reduction sponge 6 to be detected moves to the sorting position 23, if the height of the top cover 11 is at the height of the lifting slope 421, the top cover 11 will move along the lifting slope 421 driven by the annular conveyor belt 2 until it leaves the detection box 1.

[0043] like Figure 7 As shown, specifically, when the noise reduction sponge 6 to be detected moves to the sorting position 23, if the height of the top cover 11 is at the height of the downward pressing slope 411, the top cover 11 will be driven by the annular conveyor belt 2 along the lifting slope 421 until it is pressed down to the second preset height.

[0044] In some embodiments, the first preset height is higher than the second preset height. When the top cover 11 is at the first preset height, the degree of compression on the noise reduction sponge 6 is primary, and when the top cover 11 is at the second preset height, the degree of compression on the noise reduction sponge 6 is advanced. In the related art, if there is moisture in the noise reduction sponge 6, its rebound speed will be reduced. Therefore, when the height of the top cover 11 is at the height of the downward pressure slope 411, it is impossible to determine whether the noise reduction sponge 6 is unqualified or there is moisture. Therefore, when the height of the top cover 11 is at the height of the downward pressure slope 411, the noise reduction sponge 6 is squeezed to prevent the presence of moisture in the noise reduction sponge 6.

[0045] As an optional embodiment, the thickness of the noise reduction sponge 6 is 10 cm. When the top cover 11 is pressed down to a first preset height, the noise reduction sponge 6 is compressed to a thickness of 5 cm. The unit time is 5 seconds. A qualified noise reduction sponge 6 rebounds from 5 cm to a height of 7 cm to 8 cm within a unit time. A noise reduction sponge 6 that rebounds too quickly rebounds from 5 cm to a height of more than 8 cm within a unit time. A noise reduction sponge 6 that rebounds too slowly rebounds from 5 cm to a height of less than 7 cm within a unit time. When the top cover 11 is pressed down to a second preset height, the noise reduction sponge 6 is compressed to a thickness of 2 cm, thereby draining moisture.

[0046] like Figure 2 , Figure 7 As shown, in some embodiments, the guide frame 41 extends along the conveying direction of the circular conveyor belt 2, and extends from the bottom of the circular conveyor belt 2 to the starting position 21 of the circular conveyor belt 2; wherein when the rebound rate of the noise reduction sponge is too slow, the circular conveyor belt 2 drives the detection box 1 under the pressure of the top cover 11 to return from the bottom of the circular conveyor belt 2 to the starting position 21 of the circular conveyor belt 2, so that the noise reduction sponge can be subjected to secondary detection.

[0047] In this embodiment, the top cover 11 is gradually compressed to a second preset height by the downwardly pressed inclined surface 411. At this time, the top cover 11 is against the limiting protrusion 13 on the detection box 1 to press the detection box 1 onto the annular conveyor belt 2. The detection box 1, the top cover 11, and the noise reduction sponge 6 are conveyed to the starting position 21 again through the conveyance of the annular conveyor belt 2. At this time, it is ensured that there is no moisture in the noise reduction sponge 6. Then, the noise reduction sponge 6 is completely reset and tested again. If it is still conveyed to the starting position 21, it indicates that the noise reduction sponge 6 is unqualified.

[0048] like Figure 1 As shown, in some embodiments, a material receiving mechanism 5 is provided downstream of the annular conveyor belt 2; when the rebound rate of the noise reduction sponge is qualified, the annular conveyor belt 2 conveys the detection box 1 with the top cover 11 to the material receiving mechanism 5; when the rebound rate of the noise reduction sponge is too fast, the annular conveyor belt 2 conveys the detection box 1 without the top cover 11 to the material receiving mechanism 5.

[0049] In this embodiment, the material receiving mechanism 5 is used to receive the test box 1. If the received test box 1 has a top cover 11, it indicates that the noise reduction sponge 6 in the test box 1 is qualified. If the received test box 1 does not have a top cover 11, it indicates that the noise reduction sponge 6 in the test box 1 is unqualified.

[0050] In some embodiments, a guide column 12 is provided on the detection box 1; the top cover 11 is passed through the guide column 12 so as to move along the guide column 12 when subjected to force.

[0051] In some embodiments, the width of the detection box 1 is smaller than the distance between the two guide frames 41 ; the width of the top cover 11 is larger than the distance between the two guide frames 41 .

[0052] In this embodiment, the movement of the detection box 1 is not limited by the two guide frames 41 , and only the top cover 11 is limited in movement by the two guide frames 41 and the two guide blocks 42 .

[0053] In some embodiments, a plurality of push plates 21 are disposed at intervals on the surface of the endless conveyor belt 2 ; specifically, the push plates 21 function to drive the detection box 1 to move under the endless conveyor belt 2 .

[0054] At least one embodiment also provides a working method of a tire noise reduction sponge rebound time detection device, which includes: controlling the annular conveyor belt 2 to convey the detection box 1 through the control module, so that the detection box 1 passes through the starting position 21, the pressure position 22, and the sorting position 23 in sequence; controlling the pressing mechanism 3 to press down the top cover 11 to a first preset height to compress the noise reduction sponge through the control module; controlling the annular conveyor belt 2 to convey the compressed noise reduction sponge from the pressure position 22 to the sorting position 23 within a unit time through the control module; and sorting the noise reduction sponge through the sorting mechanism 4 according to the rebound height of the top cover 11 driven by the noise reduction sponge within a unit time.

[0055] In some embodiments, the sorting mechanism 4 includes two symmetrically arranged guide components; the two guide components are respectively used to guide the corresponding ends of the top cover 11, and both include: a guide frame 41, located above the circular conveyor belt 2, and a downward pressing slope 411 is provided on the lower surface; a guide block 42, located above the guide frame 41, with a channel 43 left between the guide frame 41, and a lifting slope 421 is provided on the upper surface of the guide block 42; when the rebound rate of the noise reduction sponge is qualified, the top cover 11 rebounds to the height of the channel 43 and passes through the channel 43; when the rebound rate of the noise reduction sponge is too fast, the top cover 11 rebounds to the height of the lifting slope 421, and is lifted off the base 11 by the lifting of the lifting slope 421; when the rebound rate of the noise reduction sponge is too slow, the top cover 11 rebounds to the height of the downward pressing slope 411, and is pressed down to a second preset height by the downward pressing slope 411 to squeeze the noise reduction sponge.

[0056] In some embodiments, the guide frame 41 extends along the conveying direction of the circular conveyor belt 2, and extends from the bottom of the circular conveyor belt 2 to the starting position 21 of the circular conveyor belt 2; when the rebound rate of the noise reduction sponge is too slow, the circular conveyor belt 2 drives the detection box 1 under the pressure of the top cover 11 to return from the bottom of the circular conveyor belt 2 to the starting position 21 of the circular conveyor belt 2, so that the noise reduction sponge can be subjected to secondary detection.

[0057] For the specific structure and implementation process of the tire noise reduction sponge rebound time detection device, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0058] In summary, the tire noise reduction sponge rebound time detection device and its working method press down the noise reduction sponge 6 through the pressing mechanism 3 to simulate the pressure on the noise reduction sponge 6, and then control the annular conveyor belt 2 to transport the pressed noise reduction sponge from the pressing position 22 to the sorting position 23 within a unit time, and finally sort the noise reduction sponge through the sorting mechanism 4 according to the rebound height of the top cover 11 driven by the noise reduction sponge within a unit time, so as to remove unqualified noise reduction sponges.
