Specific embodiments

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings in a non-limiting manner. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-2 , the present invention provides a technical solution: an automobile tire performance detection platform, including a conveyor belt 1 for transporting the tires to be tested. A first baffle 2 is arranged at the rear side of the conveyor belt 1, and a second baffle 3 is arranged at the front side of the conveyor belt 1. A feeding port 4 is opened on the left side of the second baffle 3 for feeding the tires to be tested. A chassis 5 is arranged at the front side of the second baffle 3. A controller is installed inside the chassis 5. A control panel 6 is fixedly installed at the front side above the chassis 5. The control panel 6 is signal-connected to the controller. A support rod 7 is fixed between the control panel 6 and the upper surface of the chassis 5 to strengthen the support for the control panel 6.

[0021] Above the chassis 5, a hydraulic cylinder 8 is also fixed. The internal pipeline of the hydraulic cylinder 8 is connected to an external liquid pump and an oil tank. An air extraction pump is also arranged inside the chassis 5. The air inlet end of the air extraction pump is connected to an air pipe 13, and the air outlet end of the air extraction pump is provided with a collection box 9. The collection box 9 is used to collect the waste extracted by the air extraction pump. The collection box 9 is slidably connected to the chassis 5. A handle 10 is fixed to the outside of the collection box 9 to facilitate the sliding and pulling out of the collection box 9. A number of air holes are provided on the outer surface of the collection box 9 facing outward to facilitate the orderly discharge of gas when the air extraction pump is working.

[0022] As Figure 3 , a round hole is provided on the surface of the second baffle 3. The output end of the hydraulic cylinder 8 passes through the round hole, and the output end of the hydraulic cylinder 8 is fixedly connected to a third motor 25. The output end of the third motor 25 is fixed with a clamping block 23. The clamping block 23 is installed in the inner ring of the tire. An annular groove is provided in the middle of the clamping block 23. A set of telescopic components are uniformly fixed on the outer wall of the annular groove for one week. The telescopic components include an electric telescopic rod 26 and a pressing block 27. A power supply is arranged inside the clamping block 23, and the power supply supplies power to the electric telescopic rod 26. In addition, the electric telescopic rod 26 is connected to the controller inside the chassis 5 through a wireless signal.

[0023] A fiber optic sensor 24 is installed on the surface of the second baffle 3 close to the clamping block 23 to determine the position of the tire. When it is detected that the tire runs to one side of the clamping block 23, the external liquid pump is controlled to start, so that the output end of the hydraulic cylinder 8 drives the clamping block 23 to move towards the first baffle 2. The clamping block 23 passes through the inner ring of the tire. Then the electric telescopic rod 26 starts, and the moving end of the electric telescopic rod 26 drives the pressing block 27 to move towards the inner wall of the tire. Through the extrusion between the pressing block 27 and the inner wall of the tire and the mutual friction force, the electric telescopic rod 26 clamps and fixes the tire, which facilitates the realization of subsequent rotation processes. When the third motor 25 starts, the tire rotates under the clamping and fixing action. A round groove 22 is provided on the surface of the first baffle 2 facing the clamping block 23. The size of the round groove 22 is consistent with the outer diameter size of the clamping block 23 to facilitate the engagement with the clamping block 23.

[0024] A set of support components is provided at the upper end of the second baffle 3. One support component is vertically arranged directly above the tire, and the other support component is obliquely arranged. The support component includes an L-shaped tube 14. A connecting block 16 is fixedly connected to the front end of the L-shaped tube 14. A second motor 17 is fixed to the lower end of the connecting block 16. The output end of the second motor 17 is fixedly connected to a threaded rod 18. A moving plate 19 is threadedly connected to the outer surface of the threaded rod 18. Fixing plates 21 are fixedly arranged on both sides of the lower surface of the moving plate 19. A limiting plate 20 is fixedly connected to the bottom end of the threaded rod 18. A limiting rod 15 is arranged through one side of the moving plate 19 for limiting the moving direction of the moving plate 19. The outer wall of the limiting rod 15 is slidably connected to the moving plate 19. The upper end of the limiting rod 15 is connected to the L-shaped tube 14, and the connection part is set to be bolt-fixed. When the second motor 17 is started, the output end of the second motor 17 drives the threaded rod 18 to rotate, thereby causing the moving plate 19 to move up and down.

[0025] As Figure 4 shown, in the support component arranged vertically to the tire, a cleaning component 11 is arranged below the moving plate 19. The cleaning component 11 includes a first motor 111 fixed to the fixing plate 21. The output end of the first motor 111 penetrates through the fixing plate 21 connected to it, and the output end is fixedly connected to a roller 112. The inside of the roller 112 is a hollow structure. A number of brush tubes 113 are evenly fixed on the surface of the roller 112. An air flow channel is opened inside the brush tube 113, and the air flow channel communicates with the inside of the roller 112. The left side of the roller 112 is connected to the other end of an air pipe 13 by a bearing. The other end of the air pipe 13 is fixed inside one side fixing plate 21. When the tire is clamped and rotated, the first motor 111 is started, and its output end drives the roller 112 to rotate to clean the dirt on the tire surface. At the same time, the air pump is started, and the fine debris generated by the cleaning enters the inside of the collection box 9 through the air flow channel and the air pipe 13, improving the sanitary environment around the entire detection table when cleaning the tire and reducing the burden of manual cleaning;

[0026] In addition, a cleaning liquid tank, a cleaning liquid pump, and a cleaning liquid pipeline can be additionally provided, so that both the air pipe 13 and the cleaning liquid pipeline communicate with the inside of the roller 112. By starting the cleaning liquid pump, the cleaning liquid is pumped out from the cleaning liquid tank and passes through the inside of the roller 112 and the air flow pipeline inside the brush tube 113. Under the action of the roller 112, the cleaning liquid is sprayed onto the outer wall of the tire and the outer wall of the tire is cleaned.

[0027] As Figure 5As shown in the figure, in the inclined support assembly, a detection assembly 12 is provided below the corresponding moving plate 19. The detection assembly 12 includes a square groove 121 which is fixedly connected to the fixed plates 21 on both sides. A friction block 124 is slidably connected inside the square groove 121. The friction block 124 is in frictional contact with the outer surface of the tire and is used to detect the friction resistance performance of the tire surface. A spring 123 is connected inside the friction block 124, and the other end of the spring 123 is connected to a tensile force detector 122. The tensile force detector 122 is an electronic device and is signal-connected to the controller. The tensile force detector 122 is fixedly installed on the outer wall of the square groove 121.

[0028] By moving the moving plate 19 up and down, the position of the detection assembly 12 or the cleaning assembly 11 can be adjusted according to the outer diameter of the tire to adapt to the detection of tires of various sizes.

[0029] An automobile tire performance detection platform is mainly used for detecting the wear resistance performance of used tires. The specific use steps are as follows:

[0030] S1: Manually place the tire from the feeding port 4 onto the conveyor belt 1, and then start the conveyor belt 1. The tire enters between the first baffle 2 and the second baffle 3. When the optical fiber sensor 24 detects the tire, the conveyor belt 1 stops running. The optical fiber sensor 24 transmits a signal to an external liquid pump, and the hydraulic cylinder 8 is started, so that the clamping block 23 fixedly clamps the inner ring of the tire, and the third motor 25 drives the tire to rotate.

[0031] S2: The moving plate 19 on the support assembly moves, respectively bringing the friction block 124 and the brush tube 113 into contact with the tire surface. The first motor 111 and the air extraction pump are both started to clean the dirt on the tire surface to improve the accuracy of the friction resistance performance detection result.

[0032] S3: The detection assembly 12 determines whether the tire surface is clean based on the tensile force change data detected by the tensile force detector 122 and obtains the friction resistance performance result of the tire.

[0033] S4: The cleaning assembly 11 adjusts the cleaning process according to the tensile force change data detected by the tensile force detector 122 to reduce the cleaning time.

[0034] S5: When the controller obtains the friction resistance performance result of the tire, the output end of the hydraulic cylinder 8 retracts, and the conveyor belt 1 is started again. The tire is conveyed to the right along with the conveyor belt 1.

[0035] S6: Repeat S1 - S5 to complete the cleaning and friction resistance performance detection of all the tires to be tested.

[0036] Specifically, the tensile tester 122 in S3 is signal-connected to the controller. When the tire rotates one week, the friction block 124 also makes frictional contact with the tire for one week. The tensile tester 122 plots a curve graph of the tensile data detected in one week, which is defined as a periodic curve. There are as many groups of periodic curves as the number of rotations of the tire. When the fluctuation degree of the obtained periodic curve is large, it indicates that the dirt on the tire surface needs to be further cleaned. When the fluctuation of the obtained periodic curve tends to be stable, the friction resistance performance is judged;

[0037] The specific steps in S4 are that when the fluctuation degree of the periodic curve is large, the controller sends an adjustment instruction to the first motor 111 and the air extraction pump. The output powers of the first motor 111 and the air extraction pump will increase, and the increase value is positively correlated with the fluctuation degree. Thus, the cleaning efficiency of the cleaning component 11 for the tire is enhanced, and at the same time, the cleaning efficiency is improved. When the fluctuation of the periodic curve tends to be stable, the controller sends a stop instruction to the first motor 111 and the air extraction pump, and the two stop running;

[0038] The method for obtaining the friction resistance performance result in S3 is that when the fluctuation of the periodic curve tends to be stable, the average value of this group of periodic curves is taken. A preset value is input in advance at the control panel 6 end, that is, the frictional force generated by the friction block 124 and the surface part of the same type of tire that has not been used. Furthermore, the tensile value detected by the tensile tester 122 is obtained. This tensile value is the preset value. The controller compares the obtained average value with the preset value, and then judges the friction resistance performance of the detected tire, which can be displayed at the control panel 6 end through the difference or ratio, facilitating the staff to mark or process the tire. Thus, the intelligent integration of tire cleaning and friction resistance performance detection is realized.
