FIG. 2 is a flowchart of a tire measurement method provided by an embodiment of the present invention, and FIG. 3 is a diagram of an operation scenario involved in the tire measurement method shown in FIG. 2 . The tire measurement method of the embodiment shown in FIG. 2 can be implemented based on the tire measurement method of the embodiment shown in FIG. 1 .

2 and 3, the tire measurement method of the embodiment of the present invention includes:

Step 201: Rotate the tire through the rotating shaft of the rotating device.

The tire measurement method of the embodiment of the present invention is applied to a tire processing system.

The tire processing system includes a rotating device, and the rotating device includes a rotating shaft, and the tire is connected with the rotating shaft. For example, as shown in FIG. 3 , the rotating shaft is snapped with the inner ring of the tire, so that the rotation of the rotating shaft drives the tire to rotate.

The tire is rotated by the rotating shaft of the rotating device, so that the tire and the measuring sensor rotate relative to each other. Specifically, the position of the measuring sensor is stationary, and the rotating shaft of the rotating device rotates the tire, thereby realizing the relative rotation of the tire and the measuring sensor.

The measurement sensor is used to measure the spatial structure of the tire. There are various specific implementation manners of the measurement sensor in the embodiment of the present invention. In the example shown in FIG. 3 , the measurement sensor is a high-speed 3D camera. Specifically, a high-speed 3D camera that can provide measurement data that is almost unaffected by contrast can be selected for rubber measurement.

In order to realize the treatment of waste tires, optionally, the tires in the embodiments of the present invention are waste tires.

It should be understood that step 201 is one of the specific implementation manners of the step of controlling the relative rotation of the tire and the measurement sensor.

Step 202: Control the laser light source to emit laser light to the tire.

Wherein, the measurement sensor includes a laser light source and an optical signal receiving device. The tire is scanned by the laser light emitted by the laser light source, and the laser reflected by the tire is received by the optical signal receiving device, so that the structure of scanning the tire can be realized.

Wherein, as shown in FIG. 3 , the extension line 304 of the laser light emitted by the laser light source 301 to the tire 303 passes through the axis around which the tire 303 rotates. This is because the waste tires are of different sizes, but the axes around which the tires 303 rotate can overlap. The axes around which it rotates coincide. In this way, the axes around which different tires 303 rotate are located at the same position, so that the tires 303 will not exceed the sensing range of the measurement sensor, and the tire structure detected by the measurement sensor will not be deformed.

The laser light source is controlled to emit laser light to the tire, and when the tire rotates, the structure of the laser scanning the tire is realized.

It should be understood that the structure of the tire in the embodiment of the present invention is the overall spatial structure of the tire.

Step 203: Receive the laser reflected by the tire through the optical signal receiving device to obtain tire scanning information.

As shown in FIG. 3 , the laser light source 301 emits laser light to the tire 303 , so that the laser scans the structure of the tire, the tire 303 reflects the laser light, and the optical signal receiving device 302 receives the laser light reflected by the tire 303 to obtain tire scanning information. Specifically, the optical signal receiving device 302 may receive part of the laser light reflected by the tire 303 . The tire scan information is the information obtained by the measurement sensor scanning the structure of the tire 303 , which can be used to analyze the structure of the tire 303 .

Steps 202 and 203 are one of the specific implementation manners of the step of scanning the tire structure by measuring the sensor to obtain tire scanning information.

Step 204: Process the tire scan information to obtain tire structure information.

The tire structure information is used to describe the spatial structure of the tire. The tire structure information can also be referred to as a 3D image.

The tire scan information is information obtained by the measurement sensor scanning the tire structure. Therefore, after the measurement sensor obtains the tire scan information, the measurement sensor or the controller can process the tire scan information to obtain tire structure information. The spatial structure characteristics of the tire can be determined through the tire structure information.

In the embodiment of the present invention, the tire structure information can be realized in various manners. For example, the tire structure information includes the aspect ratio of the tire, the size of the inner hole of the tire, and the size of the outer diameter of the tire.

Step 204 has various specific implementation manners. For example, the tire structure information can be obtained by reconstructing the spatial model of the tire by using the tire scan information.

In a specific implementation manner, when the tire scanning information is obtained by scanning the structure of the tire by measuring the sensor, the method of the embodiment of the present invention further includes: recording the rotation angle of the rotating tire. In other words, while the measurement sensor scans the structure of the tire, the rotation angle of the tire around the axis is recorded, so that the tire scanning information and the rotation angle of the tire can be synchronized. At this time, step 204 specifically includes: integrating the rotation angle and tire scan information to obtain tire structure information. Specifically, by combining the rotation angle of the tire with the angular coordinate reference system, the spatial structure of the tire can be reconstructed according to the corresponding relationship between the rotation angle of the tire and the tire scan information, so as to obtain the tire structure information. Among them, the tire structure information is used to describe the spatial structure of the tire. Such an implementation manner can reduce the amount of calculation for reconstructing the spatial structure of the tire, so that tire structure information can be obtained efficiently.

Optionally, the step of recording the rotation angle of the rotating tire specifically includes: recording the rotation angle of the rotating tire through a position encoder. Among them, the position encoder is installed on the rotating shaft.

In this way, when the tire is rotating in a circular motion, the structure of the tire is scanned by the measuring sensor to obtain the tire scanning information, that is, the 3D image of the tire is collected. Tire scan information and tire rotation angle.

A position encoder detects and records the rotation angle of the tire. For example, the position encoder includes a brush, a processor and a memory. The brush is slidably connected to the rotating shaft of the rotating device, so that the rotation of the rotating shaft can be detected, and the processor can calculate the rotation of the tire according to the data sensed by the brush. angle, and save the rotation angle of the tire in memory. Alternatively, the position encoder can also detect the rotation angle of the tire through an infrared detection device.

It should be understood that the above-mentioned three-dimensional measurement technology according to the embodiment of the present invention can scan line by line and perform image analysis, with fast measurement speed and high resolution. Accurate 3D size and position measurements are obtained, independent of tire height and color. Suitable for harsh industrial environments and long-term trouble-free operation.

Through the cooperation of the laser light source, the optical signal receiving device, and the position encoder, the three-dimensional information of the tire can be measured with high precision, and the accurate information of the spatial structure of the tire can be obtained. The waste tires sometimes have certain deformation and wear, but the tire measurement method of the embodiment of the present invention can also measure the waste tires with high precision, and obtain accurate tire structure information.

Step 205: Move the tire to the crushing device.

Crushing equipment includes water jet lances.

After obtaining the tire structure information, the tire can be crushed.

Specifically, the rotating device is moved, and the tire is driven by the rotating shaft of the rotating device, so that the tire is moved to the crushing equipment. There is a water jet spray gun on the crushing equipment, and the tire can be crushed by the water jet spray gun.

In the embodiment of the present invention, the crushing equipment is used for crushing tires, and the crushing equipment can be realized in various ways. For example, the crushing equipment includes a bracket and a water jet spray gun connected to the bracket. Or, the crushing equipment includes a casing, and the water jet spray gun is arranged in the casing, and moving the tire to the crushing equipment is to move the tire into the casing of the crushing equipment.

Step 206 : Control the moving position of the water jet spray gun according to the tire structure information.

The water jet sprayed by the water jet spray gun can be used to crush the tire. The distance between the water jet spray gun and the crushing position of the tire has an impact on the crushing effect of the tire. Therefore, in the process of crushing the tire, it is necessary to control the moving position of the water jet spray gun. , so that the distance between the water jet spray gun and the crushing position of the tire can produce a better crushing effect. For example, controlling the moving position of the water jet spray gun so that the distance between the water jet spray gun and the crushing position of the tire reaches a preset distance range, at this time, a better crushing effect can be produced. The preset distance range is, for example, 30-50 cm.

The tire structure information is used to describe the spatial structure of the tire, so that the spatial structure of the tire can be determined according to the tire structure information. The distance between the positions results in a better crushing effect. In this way, according to the tire structure information, the distance between the water jet spray gun and the tire can be controlled, and the moving position of the water jet spray gun can be precisely controlled, so as to achieve a better crushing effect on the tire.

Optionally, step 206 specifically includes: rotating the tire, and determining the current rotation angle of the tire. Then, according to the tire structure information and the current rotation angle, the position where the water jet spray gun moves is controlled. The tire structure information is used to describe the spatial structure of the tire. The tire structure information cooperates with the current rotation angle of the tire, and the specific position of the tire can be easily determined. Therefore, it is convenient to control the water jet spray gun to move to a suitable position, so that the water jet spray gun and the tire can be moved to a suitable position. The distance between the crushing positions achieves a better crushing effect.

Step 207 : control the water jet spray gun to spray water to the tire to break the tire.

The water flow from the water jet spray gun can be used to crush the tire, so as to control the water jet spray gun to spray water flow to the tire, through the impact of the water flow, the tire can be broken, and the broken tire becomes rubber powder for recycling or processing. .

It should be understood that, in the embodiment of the present invention, the water jet spray gun can separately crush the tread and sidewall of the tire, so that the tire can be fully recovered.

In order to better manage the tires, optionally, before step 201, in other words, before the step of controlling the relative rotation of the tire and the measuring sensor, the method of the embodiment of the present invention further includes: scanning the symbols on the side of the tire through the target sensor, Get tire image information. For example, the tire rotates around the axis once, the laser emitted by the target sensor scans the sidewall of the tire, the sidewall of the tire reflects the laser to the optical signal receiving device of the target sensor, and the optical signal receiving device obtains the tire image information according to the reflected laser. The symbols on the side of the tire are scanned by the target sensor to obtain tire image information, and then the tire image information is identified to obtain tire description information, wherein the tire description information and the symbols on the side of the tire are both used to describe the tire. Then, according to the tire description information, the type information of the tire is determined.

There are many types of tires, determining the type of tires can facilitate the management of tires. There are various classification criteria for the tire type information. In the embodiment of the present invention, the classification criteria for the tire type information are the brand and model of the tire. That is, the tires are divided according to the brand and model of the tire.

In the embodiment of the present invention, the target sensor is the same as the measurement sensor in the above step 202, and can scan the symbols on the side of the tire to obtain tire image information, where the tire image information is the three-dimensional structure information of the tire side.

In some examples, the tire description information may further include the aspect ratio of the tire, the size of the inner hole of the tire, the size of the outer diameter of the tire, and the like.

In the embodiment of the present invention, the steps of identifying tire image information and obtaining tire description information can be implemented in various ways. The tire image information and the information template are matched by a program, and the tire description information is determined according to the matching result. Alternatively, when identifying tire image information, if the information is missing and incomplete, the information can be manually modified and supplemented. When re-identifying a tire with the same missing information as before, the system can perform the same processing on the currently identified tire image information according to the pre-stored information that was manually modified and completed, that is, using the previously manually modified and completed information as tire description information. In this way, the recognition accuracy is continuously improved by manually editing the detection results.

Optionally, after determining the type information of the tire, the type information of the tire may be utilized. For example, step 205 specifically includes: when the type information of the tire is the same as the preset type information, moving the tire to the crushing device. In this way, the crushing equipment is matched with a preset type of tire, so that different crushing equipment can efficiently crush different types of tires, thereby improving crushing efficiency. For this reason, when the type information of the tire is the same as the preset type information, it indicates that the crushing device is suitable for crushing the tire, thereby moving the tire to the crushing device. The type information of the tire can be used as the basis for judging the similarities and differences of the type of the tire and the tire crushed by the crushing equipment.

In other embodiments of the present invention, the type information of the tires is determined, and the tires can be classified according to the type information of the tires, so as to be moved to different warehouse equipment for storage. When the tires need to be crushed, the tires are extracted from the corresponding warehouse equipment.

In this way, the tire measurement method of the embodiment of the present invention adopts the multiple scanning technology, integrates the advantages of the two-dimensional and three-dimensional imaging technology, and can perform multiple measurements according to application requirements. Multiple tasks are accomplished by measuring sensors and target sensors, and in some cases, only one measuring sensor can accomplish multiple tasks, thereby reducing integration, maintenance and accessory costs and improving cost-effectiveness.

To sum up, in the tire measurement method of the embodiment of the present invention, the relative rotation of the tire and the measurement sensor is controlled, and then the tire scan information is obtained by scanning the structure of the tire through the measurement sensor. The tire scan information is processed to obtain tire structure information, wherein the tire structure information is used to describe the spatial structure of the tire. By controlling the relative rotation of the tire and the measuring sensor, the measuring sensor can scan the structure of the tire, so as to obtain tire scanning information.
