Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0018] The embodiments of the present application provide a deviation correction and expansion width measurement system, referring to Figure 1 The deviation correction and expansion width measurement system provided by the embodiments of the present application includes a deviation correction device 110, a width measurement device 120 and a control device 130.

[0019] The deviation correction device 110 includes a first deviation correction assembly and a second deviation correction assembly, and the first deviation correction assembly is oppositely arranged with the second deviation correction assembly. The width measurement device 120 includes a first width measurement assembly and a second width measurement assembly, and the first width measurement assembly is oppositely arranged with the second width measurement assembly. The control device 130 is signal connected with the deviation correction device 110 and the width measurement device 120 respectively. The control device 130 is used to determine the current position of the inner liner in the tire based on the first width measurement assembly and the second width measurement assembly; determine the offset distance of the inner liner based on the current position and the center line position of the tire width; and control the first deviation correction assembly and / or the second deviation correction assembly to act based on the offset distance, so as to make the width center line of the inner liner coincide with the center line of the tire width.

[0020] In the embodiments of the present application, the first deviation rectifying assembly and the second deviation rectifying assembly are oppositely arranged, and the first deviation rectifying assembly and the second deviation rectifying assembly move close to or away from each other, so as to adjust the position of the tire inner liner in the tire, that is, by the first deviation rectifying assembly and / or the second deviation rectifying assembly to exert a force on the edge or a specific area of the tire inner liner, the position of the tire inner liner in the tire is changed, so that the tire inner liner is located at the preset position of the tire; the first width measuring assembly and the second width measuring assembly are oppositely arranged, and the first width measuring assembly and the second width measuring assembly move close to or away from each other, so as to detect the relative position information of the edge of the tire inner liner, and determine the overall position of the tire inner liner and the width of the tire inner liner; the oppositely arranged deviation rectifying assembly and width measuring assembly can simultaneously obtain the position data of both sides of the tire inner liner, compared with single-side detection, the actual position state of the tire inner liner can be more comprehensively reflected, the error that may occur in single detection direction is reduced, and more accurate basic data is provided for subsequent position judgment and deviation calculation; The control device 130 is signal-connected with the deviation rectifying device 110 and the width measuring device 120 respectively, can receive the detection data transmitted by the width measuring device 120, and send a control instruction to the deviation rectifying device 110, wherein, based on the detection data collected by the first width measuring assembly and the second width measuring assembly (i.e. the relative position and relationship of the edges of both sides of the tire inner liner), the current position of the tire inner liner in the tire is determined; based on the comparison between the current position of the tire inner liner and the preset position of the width center line of the tire, the deviation value (i.e. the deviation distance of the tire inner liner) between the current position of the tire inner liner and the preset position of the width center line of the tire is determined; based on the deviation distance, the corresponding action instruction is sent to the first deviation rectifying assembly and / or the second deviation rectifying assembly, if the tire inner liner deviates to one side, the deviation rectifying assembly on the corresponding side or the deviation rectifying assemblies on both sides are controlled to act cooperatively, by exerting a pushing force or a pulling force, the position of the tire inner liner is adjusted, until the width center line of the tire inner liner coincides with the center line of the tire width, so as to avoid excessive or insufficient deviation action, ensure the accuracy and efficiency of the deviation rectifying process, at the same time, by selecting single assembly or double assembly action, different deviation situations can be flexibly adapted, without relying on high-cost large-width detection equipment, the working efficiency is improved, and the detection and deviation rectifying accuracy is improved, at the same time, the overall use cost and debugging complexity of the deviation rectifying and width expanding system are reduced.

[0021] In a specific implementation, the first width measuring assembly includes a first sensor 121 and a first driving member, the first driving member drives the first sensor 121 to move towards or away from the second width measuring assembly; the second width measuring assembly includes a second sensor 122 and a second driving member, the second driving member drives the second sensor 122 to move towards or away from the first width measuring assembly; a control device is in signal connection with the first driving member and the second driving member respectively; the control device is further configured to: acquire a current first detection distance of the first sensor 121 from one edge of the inner liner of the tire; based on the current first detection distance, control the first driving member to act, so that the current first detection distance is equal to a first detection distance threshold; acquire a current second detection distance of the second sensor 122 from the other edge of the inner liner of the tire; based on the current second detection distance, control the second driving member to act, so that the current second detection distance is equal to a second detection distance threshold.

[0022] In the embodiments of the present application, as shown in Figure 2 The first width measuring assembly includes a first sensor 121 and a first driving member, the first sensor 121 is configured to detect a current first detection distance of one edge of the inner liner of the tire (i.e. the distance between the first sensor 121 and the inner liner of the tire), and the first driving member is configured to drive the first sensor 121 to move, so that the first detection distance is equal to a first detection distance threshold (i.e. the distance between the first sensor 121 and the inner liner of the tire is the detection distance of the first sensor 121); the second width measuring assembly includes a second sensor 122 and a second driving member, the second sensor 122 is configured to detect a current second detection distance of the other edge of the inner liner of the tire (i.e. the distance between the second sensor 122 and the inner liner of the tire), and the second driving member is configured to drive the second sensor 122 to move, so that the second detection distance is equal to a second detection distance threshold (i.e. the distance between the second sensor 122 and the inner liner of the tire is the detection distance of the first sensor 121), so as to ensure the consistency of the detection and position adjustment of the two edges of the inner liner of the tire, and avoid the detection or adjustment deviation caused by the functional difference of the two assemblies; Further, in the embodiments of the present application, the first driving member and the second driving member can be servo motors with encoders; the first sensor 121 and the second sensor 122 can be sensors with a linearity of 0.05 millimeters and a detection range of 10 millimeters; or sensors with different detection ranges can also be used; The control device is respectively connected with the first driving member and the second driving member, and receives a current first detection distance between the first sensor 121 and one edge of the inner liner of the tire. The control device compares the current first detection distance with a preset first detection distance threshold value, and determines whether the position of the first sensor 121 needs to be adjusted according to the comparison result. If the current first detection distance is not equal to the first detection distance threshold value, the control device sends an action instruction to the first driving member to control the first driving member to drive the first sensor 121 to move towards or away from the second width measuring assembly until the current first detection distance is equal to the first detection distance threshold value. Meanwhile, the control device receives a current second detection distance between the second sensor 122 and the other edge of the inner liner of the tire, compares the current second detection distance with a preset second detection distance threshold value, and controls the second driving member to move according to the comparison result, so that the second driving member drives the second sensor 122 to move towards or away from the first width measuring assembly until the current second detection distance is equal to the second detection distance threshold value. In this way, the first sensor 121 and the second sensor 122 are respectively located at the detection positions with a fixed distance from the corresponding edges of the inner liner of the tire, so that the detection data is stable and the accuracy and consistency of the detection of the first sensor 121 and the second sensor 122 are improved. In specific implementation, the control device is further configured to determine the first detection distance threshold value based on the first detection range of the first sensor 121, and determine the second detection distance threshold value based on the second detection range of the second sensor 122.

[0023] In the embodiments of the present application, the control device acquires the first detection range of the first sensor 121, determines the first detection distance threshold value based on the first detection range, acquires the second detection range of the second sensor 122, and determines the second detection distance threshold value based on the second detection range. The first detection range refers to the spatial range in which the first sensor 121 can effectively detect the edge of the inner liner of the tire and output accurate distance data. The second detection range refers to the spatial range in which the second sensor 122 can effectively detect the edge of the inner liner of the tire and output accurate distance data. When the first detection distance threshold value is determined based on the first detection range and the second detection distance threshold value is determined based on the second detection range, the detection distance threshold value is usually set in the middle region of the detection range or a specific interval with the highest accuracy, so as to avoid that the sensor exceeds the effective detection range due to a small position fluctuation of the inner liner of the tire, and to ensure that the sensor is always in the state with the highest detection accuracy, reduce the distance data error caused by the accuracy decrease of the edge of the detection range, and guarantee the accuracy and stability of the detection data of the sensor.

[0024] In a specific implementation, the first deviation rectifying assembly includes a first deviation rectifying member and a first moving member, the first moving member drives the first deviation rectifying member to move towards or away from the second deviation rectifying assembly; the second deviation rectifying assembly includes a second deviation rectifying member and a second moving member, the second moving member drives the second deviation rectifying member to move towards or away from the first deviation rectifying assembly; the control device is in signal connection with the first moving member and the second moving member respectively, and is configured to: determine a first deviation distance and a second deviation distance between the edge of the inner liner of the tire and the center line of the width of the tire based on the deviation distance; and determine the action of the first moving member and / or the second moving member based on the first deviation distance and the second deviation distance.

[0025] In the embodiments of the present application, the first deviation rectifying assembly includes a first deviation rectifying member and a first moving member, the first deviation rectifying member directly acts on one side edge or a specific action area of the inner liner of the tire, and adjusts the position of the inner liner of the tire by abutting against the inner liner of the tire; the first moving member drives the first deviation rectifying member to move towards or away from the second deviation rectifying assembly, so as to move the inner liner of the tire to a target position; the second deviation rectifying assembly includes a second deviation rectifying member and a second moving member, the second deviation rectifying member is oppositely arranged with the first deviation rectifying member, and the second moving member drives the second deviation rectifying member to move towards or away from the first deviation rectifying assembly, so as to move the inner liner of the tire to the target position; through the symmetrical structure of the second deviation rectifying assembly and the first deviation rectifying assembly, the inclination of the position of the inner liner of the tire caused by unilateral deviation rectification can be avoided, the posture of the inner liner of the tire during the adjustment process is ensured to be stable, and the accurate alignment of the center line is realized; The control device is in signal connection with the first moving part and the second moving part, and determines the first offset distance and the second offset distance between the tire inner liner edge and the tire width center line position based on the determined offset distance of the tire inner liner, in combination with the width parameter of the tire inner liner and the corresponding relationship between the first deviation correction part, the second deviation correction part and the tire inner liner edge, wherein the first offset distance corresponds to the deviation of the tire inner liner edge close to the first deviation correction assembly from the center line, and the second offset distance corresponds to the deviation of the tire inner liner edge close to the second deviation correction assembly from the center line. The first offset distance and the second offset distance determine the specific offset state of the two side edges of the tire inner liner relative to the center line, avoiding the lack of adjustment pertinence caused by relying only on the overall offset distance. Based on the specific values and directions of the first offset distance and the second offset distance, the moving part that needs to act is determined. For example, if only the first offset distance exceeds the allowed range, it means that the tire inner liner is only offset on one side, and the control device only sends an action instruction to the first moving part to make the first moving part drive the first deviation correction part to approach or move away from the second deviation correction assembly. The corresponding edge of the tire inner liner is pushed or pulled by the first deviation correction part until the first offset distance returns to the allowed range. If only the second offset distance exceeds the allowed range, only the second moving part is controlled to drive the second deviation correction part to act. If both of them exceed the allowed range, the first moving part and the second moving part are controlled to act simultaneously to make the two side deviation correction parts adjust the corresponding edges respectively until the first offset distance and the second offset distance both return to the allowed range, and finally realize the coincidence of the tire inner liner width center line and the tire width center line. Through the pertinence control of decomposed offset distance, the action redundancy or excessive adjustment caused by blind adjustment is avoided, the deviation correction action is accurately adapted to the offset situation, and the deviation correction accuracy is improved.

[0026] In specific implementation, the control device is further configured to: if it is determined that the first offset distance is greater than the second offset distance, control the first moving part or the second moving part to act, and then control one moving part and the second moving part to act after the first offset distance is equal to the second offset distance.

[0027] In the embodiments of the present application, the process of determining the correction action by the control device based on the first offset distance and the second offset distance is as follows: if it is detected that the first offset distance is greater than the second offset distance, the first moving part or the second moving part is controlled to move; if the first moving part is controlled to move, the control device sends a corresponding movement instruction to the first moving part, so that the first moving part drives the first correction part to move close to or away from the second correction assembly, the first offset distance is gradually reduced by the first correction part exerting an adjusting force on the edge of the tire inner liner close to the first correction assembly, and if the second moving part is controlled to move, an instruction is sent to the second moving part, so that the second moving part drives the second correction part to move, the edge of the tire inner liner close to the second correction assembly is adjusted, the second offset distance is appropriately increased (or the speed of reduction is slowed down), until the first offset distance is equal to the second offset distance, so as to avoid the position tilt caused by excessive unilateral force during subsequent adjustment, and the stability of the correction process is improved; if it is detected that the first offset distance is equal to the second offset distance, the first moving part and the second moving part are controlled to move, so that the first moving part drives the first correction part and the second moving part drives the second correction part to move at the same speed and in the same direction close to or away from each other, balanced adjusting forces are exerted on the edges of the tire inner liner by the two correction parts, the tire inner liner is pushed as a whole to move in the direction of the center line, so that the width center line of the tire inner liner is completely coincided with the center line of the tire width; by balancing the offset distances on both sides first, the problems such as tilt and wrinkle of the tire inner liner caused by directly adjusting the two offset distances simultaneously when the difference between the two offset distances is large are effectively avoided, which is especially suitable for scenes where the material of the tire inner liner is soft and easy to deform, the structural integrity of the tire inner liner is protected, the tire inner liner moves stably as a whole, time waste caused by unilateral repeated adjustment is avoided, and the correction efficiency is improved.

[0028] In specific implementation, the control device is further configured to determine a position distance between the first sensor and the second sensor based on the first driving part and the second driving part, and determine the width of the tire inner liner based on the position distance, the first detection range and the second detection range.

[0029] In the embodiment of the present application, the control device is further configured to determine a position distance between the first sensor and the second sensor based on the movement data of the first driving member and the second driving member; and determine the width of the inner liner of the tire based on the first detection range, the second detection range, and the position distance, i.e., the width of the inner liner of the tire is equal to the position distance between the first sensor and the second sensor, minus the part of the detection range of the first sensor that does not cover the inner liner of the tire, and minus the part of the detection range of the second sensor that does not cover the inner liner of the tire. For example, if the part of the detection range of the first sensor that covers the edge of the inner liner of the tire is a certain interval of the detection range of the first sensor, and the second sensor is the same, the control device determines the actual width of the inner liner of the tire by subtracting the detection range excess of the inner liner of the tire that is not covered by the two sensors from the position distance, thereby avoiding the cost increase and the problem of out-of-sync data caused by the separation of the deviation correction device and the width measuring equipment in the traditional scheme, ensuring the accuracy and real-time performance of the distance data, without additional hardware investment, and reducing the system cost.

[0030] The embodiment of the present application provides a deviation correction and width expansion measuring method, as shown in Figure 3 The control device of the deviation correction and width expansion measuring method provided by the embodiment of the present application is applicable to the control device in the deviation correction and width expansion measuring system, and the control overview process of the control device is as follows: Step 310, determining the current position of the inner liner of the tire in the tire based on the first width measuring assembly and the second width measuring assembly; Step 320, determining the offset distance of the inner liner of the tire based on the current position and the center line position of the width of the tire; Step 330, controlling the first deviation correction assembly and / or the second deviation correction assembly to act based on the offset distance, so that the center line of the width of the inner liner of the tire coincides with the center line of the width of the tire.

[0031] In an optional embodiment, the control of the first deviation correction assembly and / or the second deviation correction assembly to act based on the offset distance includes: determining the first offset distance and the second offset distance between the edge of the inner liner of the tire and the center line position of the width of the tire based on the offset distance; and determining the control of the first moving member of the first deviation correction assembly and / or the second moving member of the second deviation correction assembly to act based on the first offset distance and the second offset distance.
