[0002] In the existing technology, conveyor belts are widely used for conveying workpieces. However, after long-term use, conveyor belts are prone to wear and aging, which can cause gaps in the conveyor belt and make it difficult to tighten. This can lead to mechanical transmission errors, making it impossible for the workpiece to be accurately moved to the set position. At this time, it is necessary to correct the position of the conveyor belt moving the workpiece. Summary of the Invention

[0004] The present invention also proposes a correction device employing the above-described correction method.

[0005] According to an embodiment of the present invention, a conveyor belt correction method includes: setting a preset position of a fixed seat; driving a conveyor belt to move the fixed seat toward the preset position; obtaining the current actual position of the fixed seat, comparing the actual position with the preset position to obtain a real-time correction distance; obtaining a real-time correction speed based on the real-time correction distance; and adjusting the conveyor belt to move the fixed seat toward the preset position at the real-time correction speed.

[0006] According to the conveyor belt correction method of the present invention, the real-time correction speed can be adjusted according to the real-time correction distance, which can reduce the inertial influence when the fixed seat moves and stops at the set position, so that the fixed seat can move and stop at the set position more accurately, reduce or reduce the reciprocating movement of the fixed seat at the set position, improve the accuracy of the fixed seat moving to the set position and reduce the time required for movement, which is beneficial to improving the efficiency of workpiece transfer.

[0007] In some embodiments, the real-time correction speed is directly proportional to the real-time correction distance.

[0008] In some embodiments, obtaining the real-time correction speed based on the real-time correction distance includes: preset a maximum correction distance; obtaining the ratio of the real-time correction distance to the maximum correction distance, and using the ratio as the real-time correction ratio; and obtaining the real-time correction speed based on the real-time correction ratio.

[0009] Further, obtaining the real-time correction speed based on the real-time correction ratio includes: presetting multiple continuously distributed correction ratio intervals, each correction ratio interval corresponding to a preset correction speed; determining the correction ratio interval in which the real-time correction ratio is located based on the real-time correction ratio, and obtaining the corresponding preset correction speed as the real-time correction speed.

[0010] Furthermore, the preset multiple continuously distributed correction ratio intervals, each correction ratio interval corresponding to a preset correction speed, includes: a preset average correction speed and multiple speed ratios, each correction ratio interval corresponding to a speed ratio, and the preset correction speed is obtained by multiplying the average correction speed by the corresponding speed ratio; wherein, the multiple correction ratio intervals are continuous and monotonically decreasing, and the speed ratios corresponding to the multiple correction ratios are monotonically decreasing accordingly.

[0011] Furthermore, the speed ratio is α, where 0 < α ≤ 2.

[0012] In some embodiments, the real-time correction ratio is T, where 0 < T < 1.

[0013] In some embodiments, the conveyor belt correction method further includes: while obtaining the real-time correction distance, detecting the correction direction of the actual position relative to the set position; and the conveyor belt adjusting the real-time correction speed according to the correction direction.

[0014] In some embodiments, the belt alignment method further includes: setting a preset error allowable value; comparing the real-time alignment distance with the error allowable value; if the real-time alignment distance is greater than the error allowable value, obtaining a real-time alignment speed based on the real-time alignment distance, and driving the conveyor belt to move the fixed seat from the actual position to the set position at the real-time alignment speed; if the real-time alignment distance is less than or equal to the error allowable value, stopping the conveyor belt to keep the fixed seat at the actual position.

[0015] According to the conveyor belt correction device of the present invention, the conveyor belt correction method of the above embodiment includes: a fixed base for fixing a workpiece; a conveyor belt, the fixed base being connected to the conveyor belt, the conveyor belt driving the fixed base to move to a set position; a distance sensor for detecting the actual position of the fixed base to obtain a real-time correction distance between the actual position and the set position; and a processor electrically connected to the distance sensor and the controller of the conveyor belt to control the conveyor belt to drive the fixed base to move to the set position at the real-time correction speed.

[0016] According to the conveyor belt correction device of the present invention, the real-time correction speed can be adjusted according to the real-time correction distance, which can reduce the inertial influence when the fixed seat moves and stops at the set position, so that the fixed seat can move and stop more accurately at the set position, reduce or reduce the reciprocating movement of the fixed seat at the set position, improve the accuracy of the fixed seat moving to the set position and reduce the time required for movement, which is beneficial to improving the efficiency of workpiece transfer.

[0023] Correction device 100

[0024] Fixed base 10, conveyor belt 20, distance sensor 30, conveyor belt support platform 40. Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0027] The following description, with reference to the accompanying drawings, describes a conveyor belt correction method and correction device 100 according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the conveyor belt correction method according to an embodiment of the present invention includes:

[0029] S1: Preset position of the fixed base 10;

[0030] S2: Drive the conveyor belt 20, which will move the fixed base 10 to the set position.

[0031] S3: Obtain the current actual position of the fixed seat 10, compare the actual position with the set position, and obtain the real-time correction distance;

[0032] S4: Obtain the real-time correction speed based on the real-time correction distance;

[0033] S5: Adjust the conveyor belt 20 to correct the deviation speed in real time, and drive the fixed seat 10 to move to the set position.

[0034] It is understandable that the fixed seat 10 is used to support the workpiece. When the conveyor belt 20 moves the fixed seat 10, there is inertia. Under the action of inertia, the fixed seat 10 is difficult to stop in time at the set position. Moreover, the greater the moving speed of the fixed seat 10, the more difficult it is to stop in time at the set position. This can easily lead to the fixed seat 10 needing to move back and forth multiple times near the set position before it can accurately stop at the set position.

[0035] The set position is the position where the workpiece is operated; for example, the workpiece is clamped at the set position.

[0036] Therefore, the real-time correction speed can be adjusted according to the real-time correction distance, which can reduce the inertial influence on the fixed seat 10 when it moves and stops at the set position, so that the fixed seat 10 can move and stop at the set position more accurately, reduce or reduce the reciprocating movement of the fixed seat 10 at the set position when it moves to the set position, improve the accuracy of the fixed seat 10 moving to the set position and reduce the time required for movement, which is conducive to improving the efficiency of workpiece transfer.

[0037] It should be noted that in this application, when obtaining the current actual position of the fixed seat 10, there is no limitation on whether the fixed seat 10 is in a moving or stationary state. That is to say, when the fixed seat 10 moves close to the set position, the real-time correction distance and real-time correction speed can be obtained while the fixed seat 10 is still moving. Then, while the fixed seat 10 is still moving, the speed of the conveyor belt 20 can be adjusted to the real-time correction speed, eliminating the process of stopping and restarting the movement of the fixed seat 10 when it is close to the set position, thereby further improving the efficiency of workpiece transfer.

[0038] In this application, the movement path of the fixed seat 10 driven by the conveyor belt 20 is defined. For example, the conveyor belt 20 may extend in a straight line, and the fixed seat 10 may move along the conveyor belt 20 in a straight line. As another example, the conveyor belt 20 may be configured as a circular conveyor belt 20, and the fixed seat 10 may move along the circular path with the conveyor belt 20.

[0039] In some embodiments, the real-time correction speed is directly proportional to the real-time correction distance.

[0040] Therefore, as the fixed seat 10 gradually approaches the set position, the real-time correction distance gradually decreases, and correspondingly, the real-time correction speed gradually decreases. That is to say, the speed is greatest when it is far away from the fixed seat 10 and far from the set position, and the speed drops to the minimum when it moves to the set position. This increases the average speed of the fixed seat 10 moving to the set position while reducing the influence of inertia on the fixed seat 10 when it moves to the set position, further improving the accuracy of the conveyor belt 20 in moving the fixed seat 10 to the set position and reducing the time required for transfer.

[0041] In some embodiments, such as Figure 2 As shown, the real-time correction speed is obtained based on the real-time correction distance, including:

[0042] S4.1: Preset maximum correction distance d set ;

[0043] S4.2: Obtain the real-time correction distance d now and maximum correction distance d set The ratio, which is used as the real-time correction ratio p. now ;

[0044] S4.3: Obtain the real-time correction speed based on the real-time correction ratio.

[0045] It is understandable that the relationship of the fixed base 10 is affected by the weight of the workpiece it carries. When the weight of the workpiece increases, the overall inertia of the fixed base 10 increases, making it more difficult for it to stop moving accurately at the set position.

[0046] Specifically, the real-time correction ratio p now It is calculated using the following relationship:

[0047]

[0048] Therefore, the maximum correction distance can be used as a standard to judge the magnitude of the real-time correction distance, and the real-time correction ratio can be obtained. Under different preset maximum correction distances, the fixed seat 10 can have different real-time correction speeds at the same real-time correction distance. Specifically, when the workpiece mass carried by the fixed seat 10 is larger, the maximum correction distance increases, so the fixed seat 10 can have a smaller real-time correction speed at the same real-time correction distance, making it easier for the fixed seat 10 to stop, and thus the fixed seat 10 can be more accurately positioned.

[0049] In addition, the maximum correction distance can limit the range of distance for correcting the position of the fixed seat 10, reducing or avoiding damage caused by the fixed seat 10 moving beyond its allowable range of movement due to excessive correction range.

[0050] Furthermore, based on the real-time correction ratio, the real-time correction speed is obtained, including:

[0051] Multiple continuously distributed correction ratio ranges are preset, and each correction ratio range corresponds to a preset correction speed.

[0052] Based on the real-time correction ratio, determine the range of correction ratios and obtain the corresponding preset correction speed as the real-time correction speed.

[0053] Therefore, based on the real-time correction ratio, the real-time correction speed of the fixed base 10 at different real-time correction distances can be obtained. This allows the real-time correction speed of the fixed base 10 to decrease more uniformly during the process of moving to the set position, thereby further improving the accuracy of the fixed base 10 moving to the set position.

[0054] Furthermore, multiple continuously distributed correction ratio intervals are preset, each correction ratio interval corresponds to a preset correction speed, including: a preset average correction speed and multiple speed ratios. Each correction ratio interval corresponds to a speed ratio, and the preset correction speed is obtained by multiplying the average correction speed by the corresponding speed ratio.

[0055] Among them, multiple correction ratio ranges are continuous and monotonically decreasing, and the speed ratios corresponding to multiple correction ratios are monotonically decreasing accordingly, so as to ensure that the real-time correction speed of the fixed base 10 can decrease more evenly during the process of moving to the set position.

[0056] Therefore, a smaller real-time correction distance can result in a smaller real-time correction ratio, and a smaller real-time correction ratio can correspond to a smaller preset correction speed. In other words, as the real-time correction ratio decreases, the fixed base 10 gradually approaches the set position, and correspondingly, the real-time correction speed of the fixed base 10 can gradually decrease, allowing the fixed base 10 to be more accurately positioned at the set position.

[0057] In this application, the speed ratio can be a non-arithmetic sequence. Preferably, when the real-time correction ratio is large, the speed ratio can be set larger, and the difference in speed ratios between adjacent correction ratio intervals is larger, resulting in faster changes in the real-time correction speed and a quicker reduction in the real-time correction distance. Conversely, when the real-time correction ratio is small, the speed ratio can be set smaller, and the difference in speed ratios between adjacent correction ratio intervals is smaller, resulting in slower changes in the real-time correction speed, thereby improving the accuracy of the movement of the fixed base 10 and reducing the influence of inertia.

[0058] In some specific embodiments, five continuously distributed correction ratio intervals are preset, and five preset correction speeds correspond one-to-one with five speed ratios. Correspondingly, the five correction ratio intervals correspond one-to-one with five preset correction speeds. When the real-time correction ratio falls into different correction ratio intervals, the corresponding preset correction speed is used as the real-time correction speed of the fixed base 10.

[0059] The formula for calculating the real-time correction speed is shown below:

[0060]

[0061] Among them, v now For real-time correction speed, Let {α1, α2, α3, α4, α5} be the average correction speed, {α1, α2, α3, α4, α5} be the speed ratio, which is a monotonically decreasing sequence, and {T1, T2, T3, T4, T5} be the boundary points of the five correction ratio intervals, which are also monotonically decreasing sequences.

[0062] Furthermore, the speed ratio is α, where 0 < α ≤ 2.

[0063] Therefore, the maximum value of the real-time correction speed can be limited, reducing or avoiding excessive real-time correction speed under the same real-time correction ratio, and improving the stability of the movement of the fixed base 10.

[0064] In some embodiments, the real-time correction ratio is T, where 0 < T < 1.

[0065] Therefore, the real-time correction distance is guaranteed to be less than the maximum correction distance, and the fixed seat 10 can perform correction operations within the range of the maximum correction distance. This reduces or avoids damage caused by the fixed seat 10 moving beyond its allowable range of movement due to excessive correction range.

[0066] In some embodiments, the conveyor belt correction method further includes: while obtaining the real-time correction distance, detecting the correction direction of the actual position relative to the set position. The conveyor belt 20 adjusts the real-time correction speed according to the correction direction.

[0067] It is understandable that when the actual position of the fixed seat 10 deviates from the set position, there may be two situations: the fixed seat 10 has not moved to the set position and is still a certain distance away, or the fixed seat 10 has passed the set position and exceeded a certain distance.

[0068] Therefore, when the fixed seat 10 is in one of the two different offset positions mentioned above, the direction of the real-time correction speed is different. Thus, the direction of the real-time correction speed is set according to the offset direction of the actual position relative to the set position, which can improve the stability of the correction.

[0069] In some embodiments, such as Figure 3 As shown, the conveyor belt correction method also includes:

[0070] S3.1: Preset error allowable value, compare the real-time correction distance with the error allowable value;

[0071] S4: If the real-time correction distance is greater than the allowable error value, the real-time correction speed is obtained based on the real-time correction distance, and the conveyor belt 20 is driven to move the fixed seat 10 from the actual position to the set position at the real-time correction speed.

[0072] S6: If the real-time correction distance is less than or equal to the allowable error value, the conveyor belt 20 stops to keep the fixed seat 10 in the actual position.

[0073] Understandably, when the real-time correction distance is within the allowable error range, the workpiece on the fixed base 10 can operate normally. For example, when the real-time correction distance is within the allowable error range, the workpiece on the fixed base 10 can still be stably clamped.

[0074] like Figure 4 As shown, the conveyor belt correction device 100 according to an embodiment of the present invention employs the conveyor belt correction method of the above embodiment, and includes: a fixed base 10, a conveyor belt 20, a ranging sensor 30, and a processor.

[0075] The fixed base 10 is used to fix the workpiece. The fixed base 10 is connected to the conveyor belt 20, which moves the fixed base 10 to a set position. The distance sensor 30 is used to detect the actual position of the fixed base 10 to obtain the real-time correction distance between the actual position and the set position. The processor is electrically connected to the distance sensor 30 and the controller of the conveyor belt 20 to control the conveyor belt 20 to move the fixed base 10 to the set position at a real-time correction speed.

[0076] The correction device 100 of this application can adjust the real-time correction speed according to the real-time correction distance, which can reduce the inertial influence on the fixed seat 10 when it moves and stops at the set position, so that the fixed seat 10 can move and stop at the set position more accurately, reduce or reduce the reciprocating movement of the fixed seat 10 at the set position when it moves to the set position, improve the accuracy of the fixed seat 10 moving to the set position and reduce the time required for movement, which is conducive to improving the efficiency of workpiece transfer.

[0077] The correction device 100 of this application is used to accurately follow or reproduce a specified process, so that the output controlled variables such as the position, orientation, and state of the object can follow the input target or any change in the given value. The correction device 100 makes it very flexible and convenient to amplify, transform, and control the position according to the requirements of the control command.

[0078] In this application, the movement path of the fixed seat 10 driven by the conveyor belt 20 is defined. For example, the conveyor belt 20 may extend in a straight line, and the fixed seat 10 may move along the conveyor belt 20 in a straight line. As another example, the conveyor belt 20 may be configured as a circular conveyor belt, and the fixed seat 10 may move along the circular path with the conveyor belt 20.

[0079] In some embodiments, the conveyor belt 20 is configured as an annular conveyor belt, which has an annular guide rail. The annular guide rail consists of an inner ring, an outer ring, and a slider. The slider can roll freely between the inner ring and the outer ring, thereby achieving efficient, stable, and safe movement, suitable for horizontal and vertical transportation scenarios.

[0080] exist Figure 4 In the example, the conveyor belt correction device 100 also includes a conveyor belt support platform 40, which can provide support for the conveyor belt 20 to improve the stability of the conveyor belt 20 moving the fixed seat 10.

[0081] In some embodiments, the ranging sensor 30 is a laser ranging sensor. The laser ranging sensor uses a line-of-sight focused laser beam to emit a laser beam towards the target and then receives the laser beam reflected from the target. By measuring the time it takes for the laser beam to travel from emission to reception, the distance from the observer to the target can be calculated. Specifically, when laser ranging uses a laser sensor, a line-of-sight focused laser beam is emitted towards the target, and then the laser beam reflected from the target is received. By measuring the time it takes for the laser beam to travel from emission to reception, the distance from the observer to the target can be calculated.

[0082] In some embodiments, a servo system employs a feedback control system that precisely follows or reproduces a process. A servo system is an automatic control system that enables the output controlled variables, such as the position, orientation, and state of an object, to follow any changes in the input target (or given value). Its main task is to make it highly flexible and convenient to amplify, transform, and control the position according to control commands.

[0083] In some embodiments, the ranging period is the PLC scan cycle, which refers to the time period required for the PLC to perform one program scan operation (starting from the first instruction and executing the user program sequentially until the program ends) in the running mode.
