DETAILED DESCRIPTION OF THE INVENTION

[0015] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0017] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a production and processing device for a polyester tire provided by an embodiment of the present invention includes: A base 1, on which a bracket 9 is fixedly installed, and an outer support mechanism is installed on the base 1; A fixed seat 14 is fixedly installed on the bracket 9. The fixed seat 14 is rotatably connected to three groups of support arms 13. The end of the support arm 13 is rotatably installed with a second roller 16. Three groups of second telescopic rods 15 are rotatably installed on the fixed seat 14. The telescopic end of the second telescopic rod 15 is rotatably connected to the support arm 13; A plurality of guiding rollers 10 are rotatably arranged on the bracket 9, and the guiding rollers 10 are distributed in a circular array on the bracket 9; An imitation cutting mechanism is arranged on the base 1. The imitation cutting mechanism includes a laser distance sensor, and the imitation cutting mechanism is used to perform imitation cutting on the defects on the tire surface according to the detection results of the laser distance sensor.

[0018] In the embodiment of the present invention, during processing, the produced tire is placed on the bracket 9. At this time, the support arms 13 are in a folded state, and at this time, the support arms 13 are close to the fixed seat 14. The tire can be directly placed outside the fixed seat 14. After placement, control the second telescopic rod 15 to extend. Driven by the second telescopic rod 15, the support arms 13 will open outwards, and the distance from the center of the fixed seat 14 to the second roller 16 gradually increases until the second roller 16 contacts the inner wall of the tire. During the rotation of the support arms 13, the external outer support mechanism also moves accordingly, so as to contact the tire at the same position of the tire, and the inside and outside are in mutual contact, which can ensure the stability of clamping. Driven by the outer support mechanism, the tire will rotate. After the tire is fixed, the imitation cutting mechanism drives the laser distance sensor to scan the outer surface of the tire, constructs a three-dimensional model of the outer surface of the tire according to the scanning results, and cuts the defects on the tire surface according to the three-dimensional model of the tire outer surface.

[0019] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, as a preferred embodiment of the present invention, the outer support mechanism includes a guide ring 11. A fixed guide rail is provided on the base 1, and the guide ring 11 is installed on the fixed guide rail. A first toothed ring 20 is fixedly provided on the guide ring 11. A second motor 12 is fixedly installed on the base 1. A first spur gear 19 is fixedly installed on the output shaft of the second motor 12. The first spur gear 19 meshes with the first toothed ring 20. Three sets of side brackets are fixedly provided on the guide ring 11. A first telescopic rod 3 is fixedly installed on the side brackets. The telescopic end of the first telescopic rod 3 is fixedly installed with a mounting seat 4. A first roller 8 is rotatably installed on the mounting seat 4. A first motor 6 is also fixedly installed on the mounting seat 4. A first bevel gear 5 is fixedly installed on the output shaft of the first motor 6. A second bevel gear 7 is fixedly installed on the first roller 8. The first bevel gear 5 meshes with the second bevel gear 7.

[0020] In this embodiment, a rotating seat 2 is fixedly installed on the guide ring 11. The rotating seat 2 is used to prevent machining debris from splashing. The tire is placed on the bracket 9. Through the synchronous expansion of multiple sets of support arms 13, the tire is fixed from the inside of the tire. After the second roller 16 contacts the inner wall of the tire, the telescopic length of the second telescopic rod 15 is obtained. The position of the second roller 16 is calculated according to the telescopic length of the second telescopic rod 15. The second motor 12 is controlled to rotate according to the position of the second roller 16. The second motor 12 drives the first spur gear 19 to rotate. The first spur gear 19 will drive the guide ring 11 to rotate along the fixed guide rail. The first telescopic rod 3 will also rotate accordingly until the line connecting the center of the fixed seat 14 and the second roller 16 is parallel to the axis of the first telescopic rod 3. At this time, the first telescopic rod 3 extends. The first telescopic rod 3 will drive the first roller 8 to move through the mounting seat 4 until the first roller 8 abuts against the outer wall of the tire. At this time, the first roller 8 and the second roller 16 are located on the inner and outer sides of the tire, and the contact positions are the same. Even if the clamping force is increased, the tire will not be deformed, ensuring the machining accuracy. When it is necessary to control the rotation of the tire, the first motor 6 is started. The first motor 6 drives the first bevel gear 5 to rotate. The first bevel gear 5 meshes with the second bevel gear 7. Therefore, after the first motor 6 is started, the first roller 8 will drive the tire to rotate through friction.

[0021] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the profiling cutting mechanism includes a mounting bracket and a circular guide rail 17. The mounting bracket is fixedly installed on the base 1. A guide rod 26 is fixedly provided on the mounting bracket. The guide rod 26 is arranged along the radial direction of the base 1. A threaded rod 27 is also rotatably provided on the mounting bracket. A slider is slidably provided on the guide rod 26. The circular guide rail 17 is fixedly installed on the slider. A guide groove is provided on the circular guide rail 17. A sliding seat 23 is slidably provided in the guide groove. A third motor 21 is fixedly installed on the sliding seat 23. The output shaft of the third motor 21 is fixedly connected to a second spur gear 22. A second toothed ring is provided on the circular guide rail 17. The second spur gear 22 meshes with the second toothed ring. A third telescopic rod 18 is rotatably provided on the sliding seat 23. A cutting edge 28 is fixedly installed at the end of the third telescopic rod 18. A fourth telescopic rod 24 is also rotatably installed on the sliding seat 23. The telescopic end of the fourth telescopic rod 24 is rotatably connected to the third telescopic rod 18. The laser distance sensor is fixedly installed on the sliding seat 23. The detection direction of the laser distance sensor points to the center of the circular guide rail 17.

[0022] In this embodiment, the threaded rod 27 is driven by the fourth motor 25 on the mounting bracket. By starting the fourth motor 25, the threaded rod 27 can be driven to rotate. The threaded rod 27 will drive the circular guide rail 17 to move along the guide rod 26. After the tire is fixed, the third motor 21 is started, and the third motor 21 is used to drive the second spur gear 22 to rotate. Since the second spur gear 22 meshes with the second toothed ring on the circular guide rail 17, when the third motor 21 is started, the sliding seat 23 will move along the circular guide rail 17. The laser distance sensor is fixed on the sliding seat 23, so it will continuously measure during the movement. During the measurement process, the laser distance sensor moves to one end of the circular guide rail 17 and starts to measure. At this time, the tire rotates continuously. Multiple sampling positions are set on the movement trajectory of the laser distance sensor, and the sampling time for each sampling position is a fixed value. After completing one sampling, it moves to the next sampling position, so as to obtain the single sampling data corresponding to each sampling position. According to the single sampling data, the detection distance corresponding to the sampling position can be determined, that is, the distance between the laser distance sensor and the tire at the detection position. Multiple detection points are constructed in the three-dimensional coordinate system according to the detection distances of all points, and the tire surface curve model is constructed according to the monitoring points. After obtaining the tire surface curve model, the cutting edge 28 can be controlled to move so that the cutting edge 28 is always tangent to the tire surface, and a preset distance, such as 2 mm, is maintained between the two. During the process of adjusting the cutting edge, the distance between the cutting edge 28 and the tire can be controlled by controlling the third telescopic rod 18, and the angle between the cutting edge 28 and the tire surface can be changed by controlling the fourth telescopic rod 24 to extend and retract. Through the cooperation of the third telescopic rod 18 and the fourth telescopic rod 24, it can be ensured that the cutting edge 28 moves along the tire surface. During the rotation of the tire, the defects on the tire surface, such as burrs or flash, will be cut off.

[0023] In the embodiment of the present invention, the tire is detected by a laser distance sensor, and the steps include: Position the tire from the inside through the cooperation of multiple groups of support arms 13, and drive the tire to rotate from the outside through the outer support mechanism. Control the laser distance sensor to detect the tire along the circular guide rail 17, and continuously measure at each detection position. During this period, the tire rotates one week to obtain single detection data.

[0024] Construct a single detection curve based on the single detection data, statistically analyze the single detection curve, and extract the tire distance at the detection position. Construct a tire surface curve model according to the tire distances at all detection positions, and control the profiling cutting mechanism to cut along the tire surface according to the tire surface curve model.

[0025] In this step, when the laser ranging sensor moves to a measurement position, continuous detection is performed at this position to obtain single detection data. A two-dimensional coordinate system is constructed with time as the horizontal axis and distance value as the vertical axis. Each measurement data is converted into a point in the two-dimensional coordinate system, and all points are sequentially connected by a smooth curve to obtain a single detection curve. The single detection curve is the detection result on an annular line of the tire surface. Sampling is performed on the single detection curve at a preset interval, and the distance value of each sampling point is statistically analyzed. The mode of the distance values is used as the tire ranging value at this detection position, and thus the tire ranging values at each detection position are obtained. A three-dimensional coordinate system is constructed, and all tire ranging values are marked in the plane where the X-axis and Y-axis are located, and the cross-sectional view of the outer surface of the tire is obtained by connecting with a smooth curve. The diameter of the tire is calculated based on the tire ranging value measured when the laser ranging sensor is parallel to the tire side surface. The cross-sectional view is circularly scanned according to the diameter of the tire, and the scanning radius is the radius of the tire, thereby obtaining the tire surface layer curved surface model. The angle and position of the cutting edge 28 at each detection position are determined according to the surface model of the tire, so as to control the cutting edge 28 to clean the burrs and frayed edges on the tire surface.

[0026] As a preferred embodiment of the present invention, the device further includes a robotic arm, on which a tire clamp is installed. The tire clamp is used for picking up and placing the tire, and a fence is arranged around the base 1.

[0027] In an embodiment of the present invention, during the process of positioning the tire, the telescopic length of the second telescopic rod 15 is monitored, and the position of the current second roller 16 is determined according to the telescopic length of the second telescopic rod 15. A pressure sensor is arranged at the connection between the second telescopic rod 15 and the support arm 13, and the clamping force is determined according to the pressure value of the pressure sensor.

[0028] In this embodiment, during the movement of the support arm 13, the value of the pressure sensor is monitored. When the value of the pressure sensor reaches the first preset value, it is determined that the second roller 16 has contacted the inner wall of the tire. At this time, the pressure value detection continues. When the pressure value rises to the second preset value, it indicates that the first roller 8 has contacted the tire on the outside of the tire, forming a clamping of the tire.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
