Description

Technical Field

[0001] The present invention belongs to the technical field of track detection, and more specifically, relates to a curved track assembly method, a computer program and an electronic device. Background Art

[0002] Overhead handling system (OHT) is an important automatic handling system in semiconductor manufacturing plants. It can improve material transportation efficiency, reduce labor costs, and reduce workshop space occupancy, in order to fundamentally improve the overall production process.

[0003] The crane track in the crane handling system is composed of multiple sections of track, and the same is true for the curved part, which will cause errors when the curved part is connected. For example, when the curved rails of the curved part of the crane track are connected, if the coaxiality of the outer curved rail relative to the inner curved rail does not meet the standard, the crane will vibrate, thereby damaging the carried objects and affecting the operation of the crane. Therefore, how to quickly and accurately assemble the curved rails has become a problem that needs to be solved urgently. Summary of the invention

[0004] To achieve the above object, the present invention provides a curved rail assembly method in a first aspect, comprising the following steps:

[0005] A curved rail setting step of concentrically setting a first curved rail and a second curved rail;

[0006] A detection step, measuring radial distance data between corresponding parts of at least two groups of the first curved rail and the second curved rail at the same circumferential angle;

[0007] Comparison step: comparing the two sets of radial distance data with the standard radial distance data to obtain a first difference. If the first difference is within a preset error range, it is determined that the curved track setting is completed; if the first difference is outside the preset error range, the following steps are entered:

[0008] Replacement step: replace at least one curved rail, and repeat the curved rail setting step, the detection step and the comparison step until the curved rail setting is completed.

[0009] A further technical solution may also be that, in the detection step, at least three sets of radial distance data are obtained; wherein, along the circumferential direction, the three sets of radial distance data are first radial distance data, second radial distance data and third radial distance data in sequence;

[0010] In the comparison step, if the first difference is outside the preset error range, the following determination is continued:

[0011] If the first radial distance data, the second radial distance data, and the third radial distance data increase or decrease in sequence, it is determined that there is an installation error between the first curved rail and the second curved rail, and the following sub-steps are entered:

[0012] Re-setting the first curved rail and the second curved rail;

[0013] Otherwise, it is determined that at least one of the first curved rail and the second curved rail has a processing error, and the replacement step is entered.

[0014] A further technical solution may be that, in the comparison step, if the first difference is outside a preset error range, the following judgment is continued:

[0015] If the first differences obtained by subtracting the standard distance data from the multiple sets of radial distance data are all positive or negative, proceed to the following sub-steps:

[0016] Selecting a first difference with the smallest absolute value from a plurality of first differences as a correction parameter;

[0017] subtracting the correction parameter from each of the plurality of radial distance data to obtain corresponding new radial distance data;

[0018] The new radial distance data is compared with the standard radial distance data to obtain a second difference. If the second difference is within a preset error range, it is determined that there is an installation error in the curved rail, and the following sub-steps are entered:

[0019] If the first difference is positive, the first curved rail and the second curved rail are pushed to move toward each other;

[0020] If the first difference is negative, the first curved rail and the second curved rail are pushed to move away from each other;

[0021] After the movement is completed, the curved track setting step, the detection step and the comparison step are repeated.

[0022] A further technical solution may be that, in the detection step, at least two groups of radial distance data correspond to two ends of the curved track along the circumferential direction respectively.

[0023] A further technical solution may also be that, before the comparison step, it further comprises:

[0024] Data screening step: comparing two sets of radial distance data corresponding to adjacent parts to obtain a third difference value, and if the third difference value is within a preset deviation range, the radial distance data is determined to be qualified;

[0025] Otherwise, it is determined that the radial distance data is invalid, and new radial distance data is remeasured.

[0026] A further technical solution may be that the first curved track is composed of a plurality of first sub-curved tracks;

[0027] In the data screening step, the preset deviation range includes:

[0028] The curve track deviation range is applicable when the parts corresponding to the two sets of radial distance data are located in the same section of the first sub-curved track;

[0029] The connection deviation range is applicable when a portion corresponding to a set of radial distance data is located at a connection point between two adjacent sections of the first sub-curved rail.

[0030] A further technical solution may also be that, in the comparison step, if the first radial distance data, the second radial distance data and the third radial distance data increase or decrease in sequence;

[0031] The corresponding part on the first curved track corresponding to the larger radial distance data is pushed toward the direction where the corresponding part of the second curved track is located; and the curved track setting step, the detection step and the comparison step are repeated.

[0032] A further technical solution may also be that the detection step includes:

[0033] A first running part of the detection device is clamped on the first curved track, and a second running component of the detection device is clamped on the second curved track;

[0034] Pushing the first running part and the second running assembly to move away from each other, so that the first running part abuts against the first curved rail, and the second running assembly abuts against the second curved rail;

[0035] The detection device is pushed along the path of the curved track to obtain the distance data between the first measuring component calibrated by the first running component and the second measuring component calibrated by the second running component, thereby obtaining the radial distance data.

[0036] A second aspect of the present invention provides a computer program product, which can implement the above-mentioned curved rail assembly method when the computer program of the computer program product is executed.

[0037] A third aspect of the present invention provides an electronic device, comprising a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the curved rail assembly method described above can be implemented.

[0038] The curved rail assembly method disclosed in the present invention can conveniently and accurately assemble the curved rail by measuring radial distance data between corresponding parts of a first curved rail and a second curved rail at multiple circumferential angles, and comparing the multiple radial distance data with standard radial distance data to determine the setting of the curved rail.

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The inventor of the present application has found that coaxiality represents the "fluctuation" of the center of a curve, that is, the degree of deviation of the center of the curve. When measuring coaxiality in a curve, the fluctuation of the center of the curve can be reflected in the form of radial circular runout, so that the technical effect equivalent to measuring coaxiality can be obtained by measuring radial circular runout.

[0050] Therefore, the applicant of this patent hopes to propose a curved rail radial runout detection device for detecting the radial runout of the curved rail, thereby obtaining a technical effect equivalent to measuring coaxiality.

[0051] In view of this, the inventor of this patent proposed a curved rail assembly method based on the radial circular runout of the curved rail to be compatible with the above-mentioned curved rail radial circular runout detection device.

[0052] The curved track assembly method, computer program product and electronic device provided by the present invention are described in detail below in conjunction with specific embodiments.

[0053] Implementation Method 1

[0054] The first aspect of this embodiment discloses a curved rail assembly method, such as Figure 1 As shown, the following steps are included:

[0055] A curved rail setting step of concentrically setting a first curved rail 11 and a second curved rail 12;

[0056] A detection step of measuring radial distance data between corresponding parts of at least two groups of the first curved rail 11 and the second curved rail 12 at the same circumferential angle;

[0057] Comparison step: comparing the two sets of radial distance data with the standard radial distance data to obtain a first difference. If the first difference is within a preset error range, it is determined that the curved track setting is completed; if the first difference is outside the preset error range, the following steps are entered:

[0058] Replacement step: replace at least one curved rail, and repeat the curved rail setting step, the detection step and the comparison step.

[0059] In this embodiment, in the curved rail setting step, the first curved rail 11 and the second curved rail 12 are concentrically set. It can be understood that the first curved rail 11 and the second curved rail 12 are essentially the inner curved rail and the outer curved rail that cooperate with each other, wherein the inner curved rail and the outer curved rail cooperate to form the overhead crane track in the overhead crane transport system. Figure 4As shown, the first curved rail 11 refers to the inner curved rail, and the second curved rail 12 refers to the outer curved rail; in some other embodiments, the first curved rail may be the outer curved rail, and the second curved rail may be the inner curved rail. It should be noted that in the above description, the first and second expressions are only used to distinguish between the two curved rails (the inner curved rail and the outer curved rail), and do not specifically refer to one of the curved rails.

[0060] It should be noted that if the assembly of the first curved rail 11 and the second curved rail 12 meets the requirements, that is, the coaxiality of the first curved rail 11 and the second curved rail 12 meets the requirements, the radial distance between the corresponding parts of the first curved rail 11 and the second curved rail 12 at the same circumferential angle is the same. Therefore, by measuring the radial distance between the corresponding parts of the first curved rail 11 and the second curved rail 12 at at least two circumferential angles, and comparing the measured radial distance data with the standard radial distance data, it can be determined whether the assembly of the first curved rail 11 and the second curved rail 12 meets the requirements. In addition, considering the processing error of the curved rail and the existence of the processing error, it is only necessary that the first difference between the measured radial distance data and the standard radial distance data is within the preset error range, that is, it can be determined that the assembly of the curved rail meets the requirements, that is, the curved rail (the first curved rail 11 and the second curved rail 12) is set. If the first difference is outside the preset error range, the replacement step is entered to replace at least one curved rail, and the curved rail setting step, the detection step and the comparison step are repeated. For example, assuming that the two sets of radial distance data measured are a and b, the standard radial distance data is x, and the preset error range is ±y, if |ax|<y and |bx|<y, then it is determined that the curved track is set. It is worth noting that in this embodiment, if the first difference between any set of radial distance data and the standard radial distance data among the multiple sets of radial distance data measured is outside the preset error range, it is determined that the curved track is not set.

[0061] In some embodiments, one of the curved rails may be installed at a designated position first, and the curved rail may be used as a reference to install another curved rail that cooperates with the curved rail, and the curved rail assembly method described above may be used to assemble the latter curved rail. For example, the inner curved rail may be installed first, and the outer curved rail may be installed using the inner curved rail as a reference, and the curved rail assembly method described above may be used to install the outer curved rail. Alternatively, the outer curved rail may be installed first, and the inner curved rail may be installed using the outer curved rail as a reference, and the curved rail assembly method described above may be used to install the inner curved rail.

[0062] It is worth mentioning that, in order to further improve the accuracy of the determination, the measurement locations of the first curved rail 11 and the second curved rail 12 may be increased to obtain more radial distance data corresponding to different locations.

[0063] The curved rail assembly method disclosed in this embodiment can conveniently and quickly determine the setting condition of the curved rail by measuring the radial distance data between corresponding parts of the first curved rail 11 and the second curved rail 12 at multiple circumferential angles, and comparing the multiple radial distance data with the standard radial distance data to determine the setting condition of the curved rail.

[0064] In this embodiment, a curved rail radial runout detection device can be used to measure the radial distance data between the first curved rail 11 and the second curved rail 12. Specifically, Figure 2 As shown, the curved rail radial runout detection device comprises:

[0065] A first rod 6;

[0066] A first running part 2, connected to the first rod 6;

[0067] The second running assembly 3 is movably connected to the first rod 6; the first running part 2 and the second running assembly 3 can move away from each other, so that the first running part 2 abuts against the first curved rail 11, and the second running assembly 3 abuts against the second curved rail 12;

[0068] A first measuring component 4, arranged on the first running part 2;

[0069] The second measuring component 5 is disposed on the second running assembly 3, and measures the distance data between the first running unit 2 and the second running assembly 3 through the first measuring component 4 and the second measuring component 5, thereby obtaining the radial distance data between the first curved rail 11 and the second curved rail 12. In this embodiment, one of the first measuring component 4 and the second measuring component 5 is a rangefinder, and the other is a reflector.

[0070] Accordingly, the detection step comprises:

[0071] A first running part 2 of the detection device is clamped on the first curved rail 11, and a second running component 3 of the detection device is clamped on the second curved rail 12;

[0072] Push the first running part 2 and the second running component 3 to move away from each other, so that the first running part 2 abuts against the first curved rail 11, and the second running component 3 abuts against the second curved rail 12;

[0073] The detection device is pushed along the path of the curved track to obtain the distance data between the first measuring component 4 calibrated by the first running component 2 and the second measuring component 5 calibrated by the second running component 3, thereby obtaining the radial distance data.

[0074] When the detection device is pushed to move along the path of the curved rail, radial distance data of corresponding parts of the first curved rail 11 and the second curved rail 12 at multiple circumferential angles can be obtained. In this embodiment, two or more groups of radial distance data can be selected to enter the comparison step.

[0075] Since the first measuring component 4 is arranged on the first running part 2, and the second measuring component 5 is arranged on the second running assembly 3; when the second running assembly 3 slides relative to the first rod 6, the second measuring component 5 arranged on the second running assembly 3 will follow and move synchronously, so that the distance between the first measuring component 4 and the second measuring component 5 changes. In some embodiments, the first rod 6 can be arranged to be collinear with the radial direction of the curved track, and the connecting line of the first measuring component 4 and the second measuring component 5 is the radial direction of the curved track; at this time, the distance between the first measuring component 4 and the second measuring component 5 is the radial distance. In some other embodiments, the first rod 6 can be arranged to form a certain angle with the radial direction of the curved track, and the distance between the first measuring component 4 and the second measuring component 5 is the non-radial distance; at this time, it is necessary to convert the distance data measured and the angle between the connecting line direction of the first measuring component 4 and the second measuring component 5 and the radial direction of the curved track to obtain the distance between the first curved track 11 and the second curved track 12 in the radial direction, that is, to obtain the radial distance data of the first curved track 11 and the second curved track 12 at a certain circumferential angle.

[0076] It should be noted that the positions marked by the first running unit 2 and the second running component 3 are relative positions, that is, when the detection device is placed at any position on the curved track, the first running unit 2 can correspond to a certain position on the first curved track 11 and mark a relative position. The second running component 3 can correspond to another relative position on the second curved track 12. The relative position marked by the first running unit 2 and the second running component 3 is equivalent to the mapping of the relative position on the first curved track 11 and the second curved track 12 corresponding thereto, so that by measuring the distance change between the two calibrated relative positions, the distance change between the relative positions on the inner curved track and the outer curved track can be reflected, thereby obtaining radial distance data at a certain circumferential angle. For example, the relative position marked by the first running unit 2 can be 5 cm above a specific point of the contact part between the first running unit 2 and the first curved track 11. No matter how the first running unit 2 moves on the first curved track 11, this calibrated position always moves 5 cm above the specific point of the relative contact part. The second running component 3 is the same.

[0077] It is worth mentioning that in some other embodiments, other methods may be used to obtain the radial distance data between corresponding parts of the first curved rail 11 and the second curved rail 12 at the same circumferential angle, and are not limited to the above-mentioned detection device.

[0078] In some implementations, such as Figure 3 and Figure 4 As shown, the second running assembly 3 includes two second running parts 31 and a second rod 32. The two second running parts 31 are respectively arranged on both sides of the first rod 6. The second rod 32 connects the two second running parts 31 and is slidably arranged on the first rod 6. The two second running parts 31 can slide on the second rod 32. Specifically, as Figure 3 and Figure 4 As shown, the second rod 32 is slidably disposed on the first rod 6, and the second rod 32 is disposed at an angle to the first rod 6; the two second running parts 31 are respectively located on both sides of the first rod 6 and connected to the second rod 32, and the second running parts 31 can slide on the second rod 32. In this embodiment, the two second running parts 31 are used to abut against the outer curved track, and are respectively located on both sides of the first rod 6; when the detection device moves along the curved track path, the second rod 32 can move on the first rod 6; and because the two second running parts 31 are respectively located on both sides of the first rod 6, the detection device can keep the first rod 6 stable during the movement along the curved track path, that is, keep the angle between the first rod 6 and the radial direction unchanged, thereby improving the accuracy of the detection data. It is worth mentioning that in this embodiment, by setting two second running parts 31, the detection device has three parts (i.e., two second running parts 31 and the first running part 2) abutting against the curved track, which can significantly improve the stability of the detection device moving on the curved track. In this embodiment, the second measuring part 5 is set at the intersection of the second rod 32 and the first rod 6, so that the second measuring part 5 can be located at the center of gravity of the detection device, which can effectively improve the stability of the detection device; and the second measuring part 5 is set at this position, so that the first measuring part 4 and the second measuring part 5 are both located in the length extension direction of the first rod 6, which is conducive to the conversion of distance data.

[0079] It is worth mentioning that, since the second running parts 31 can move on the second rod 32 , the distance between the two second running parts 31 can be changed to adapt to curved tracks with different curvatures, thereby improving the adaptability of the detection device.

[0080] In addition, in some other embodiments, data comparison can also be performed in the form of images. Specifically, the detection device is pushed so that the detection device moves along the curved track from one end to the other end of the curved track to obtain radial distance data. In some embodiments, the detection device can be pushed to move at a uniform speed, record the time and radial distance data, and make a coordinate graph corresponding to the radial distance data, wherein the x-axis is time and the y-axis is radial distance. At the same time, a tolerance band (two lines parallel to the x-axis corresponding to the positive tolerance and the negative tolerance, respectively) is drawn on the coordinate graph according to the standard radial distance data and the error range. The operator can intuitively judge the assembly condition of the curved track through the coordinate graph. In addition, if radial distance data outside the tolerance band appears, the position corresponding to the radial distance data on the curved track can be quickly determined according to its corresponding horizontal coordinate and the moving speed of the detection device. In some other embodiments, the detection device can be pushed to move, and the radial distance data can be recorded every time it moves a set distance, and a coordinate graph corresponding to the radial distance data can be made, wherein the x-axis is the moving distance and the y-axis is the radial distance; in this embodiment, if radial distance data outside the tolerance zone appears, the position corresponding to the radial distance data on the curved track can be quickly determined based on its corresponding horizontal coordinate (moving distance).

[0081] The second aspect of this embodiment further discloses a computer program product. When the computer program of the computer program product is executed, the curved rail assembly method described above can be implemented.

[0082] The third aspect of this embodiment further discloses an electronic device, including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the curved rail assembly method described above can be implemented.

[0083] Implementation Method 2

[0084] The first embodiment discloses a method for assembling a curved track, which measures the radial distance data between the corresponding parts of the first curved track 11 and the second curved track 12 at multiple circumferential angles, and compares the multiple radial distance data with the standard radial distance data to determine the setting of the curved track. In the first embodiment, only the setting of the curved track can be determined, and the cause of the error in the curved track cannot be determined. Therefore, the second embodiment proposes a method for assembling a curved track, which is a further improvement based on the first embodiment, and the improvement is:

[0085] In the detection step, at least three sets of radial distance data are obtained; wherein, along the circumferential direction, the three sets of radial distance data are first radial distance data, second radial distance data and third radial distance data in sequence;

[0086] In the comparison step, if the first difference is outside the preset error range, the following determination is continued:

[0087] If the first radial distance data, the second radial distance data and the third radial distance data increase or decrease in sequence, it is determined that there is an installation error between the first curved rail 11 and the second curved rail 12, and the following sub-steps are entered:

[0088] Re-arrange the first curved rail 11 and the second curved rail 12;

[0089] Otherwise, it is determined that at least one of the first curved rail 11 and the second curved rail 12 has a processing error, and the replacement step is entered.

[0090] Specifically, when both the first curved rail 11 and the second curved rail 12 meet the processing requirements, if the first curved rail 11 is deflected at a certain angle relative to the second curved rail 12, this makes one side of the first curved rail 11 close to the second curved rail 12, while the other side is far away from the second curved rail 12; from the measured radial distance data, the radial distance data measured along the circumferential direction of the curved rail will show a pattern of gradually decreasing or gradually increasing. If there is a processing error in one of the first curved rail 11 or the second curved rail 12, the measured radial distance data will show a state of fluctuating and irregular. Therefore, according to the change law of the radial distance data measured along the circumferential direction, it can be determined whether the cause of the curved rail setting error is caused by the installation error of the first curved rail 11 and the second curved rail 12, or by the processing error in one or both of the first curved rail 11 and the second curved rail 12.

[0091] Through the above method, the cause of the curve rail setting error can be quickly determined through the measured radial distance data, so as to determine whether the next operation is to reset the first curve rail 11 and the second curve rail 12, or to replace the first curve rail 11 or the second curve rail 12, thereby greatly saving time and improving the efficiency of curve rail assembly.

[0092] It is worth noting that, in this embodiment, it is necessary to determine whether there is a processing error in the curved track through the measured radial distance data. Therefore, in order to further improve the accuracy of the judgment, in the detection step, at least two groups of the radial distance data correspond to the two ends of the curved track along the circumferential direction. In this way, among the measured radial distance data, there are at least two ends corresponding to the curved track along the circumferential direction, which can more comprehensively reflect the shape of the curved track. Moreover, in order to further improve the accuracy of the judgment, multiple measurements can be performed on multiple locations between the two ends of the curved track along the circumferential direction to obtain multiple groups of radial distance data. In this way, the measured multiple groups of radial distance data can be more evenly distributed at the two ends and the middle part of the curved track, so as to better reflect the overall shape of the curved track, thereby improving the accuracy of the judgment.

[0093] In some preferred embodiments, in the comparison step, if the first radial distance data, the second radial distance data and the third radial distance data increase or decrease in sequence;

[0094] The corresponding part on the first curved rail 11 corresponding to the larger radial distance data is pushed toward the direction where the corresponding part of the second curved rail 12 is located; and the curved rail setting step, the detection step and the comparison step are repeated.

[0095] As can be seen from the above, when both the first curved rail 11 and the second curved rail 12 meet the processing requirements, if the first curved rail 11 is deflected by a certain angle relative to the second curved rail 12, one side of the first curved rail 11 is close to the second curved rail 12, while the other side is far away from the second curved rail 12; from the measured radial distance data, the radial distance data measured along the circumferential direction of the curved rail will show a rule of gradually decreasing or gradually increasing. Therefore, according to the change rule of the radial distance data measured along the circumferential direction, the adjustment method of the curved rail can also be determined. For example, the first curved rail 11 is deflected relative to the second curved rail 12, so that the left side of the first curved rail 11 is close to the second curved rail 12, and the right side is far away from the second curved rail 12. From the measured radial distance data, along the circumferential direction of the curved rail, from left to right, the measured radial distance data shows a change rule of gradually increasing; the corresponding radial distance data close to the left is larger. Therefore, when resetting the curved track, the left side of the first curved track 11 (the corresponding part on the first curved track 11 corresponding to the larger radial distance data) is pushed toward the direction of the corresponding part of the second curved track 12, so that the first curved track 11 is deflected in another direction relative to the second curved track 12.

[0096] In some embodiments, in the step of pushing the curved track, it can be set to push a set distance, that is, each time the curved track is pushed a set distance, the curved track setting step, the detection step and the comparison step are repeated. In this way, the distance of each curved track movement can be controlled, that is, the amplitude of the curved track adjustment can be controlled, which is conducive to more accurate setting of the curved track.

[0097] Implementation Method 3

[0098] In the second embodiment, by the change rule of the radial distance data measured along the circumferential direction, it is possible to judge whether the curved rail meets the processing requirements, confirm the deflection of the curved rail, and provide an adjustment method. However, during the assembly process of the curved rail, one curved rail may deviate in a direction away from or close to another curved rail. Therefore, relying solely on the method in the second embodiment, the assembly of the curved rail cannot be well achieved. Therefore, this embodiment discloses a curved rail assembly method, which is a further improvement based on the second embodiment, and the improvement is:

[0099] In the comparison step, if the first difference is outside the preset error range, the following determination is continued:

[0100] If the first differences obtained by subtracting the standard distance data from the multiple sets of radial distance data are all positive or negative, proceed to the following sub-steps:

[0101] Selecting a first difference with the smallest absolute value from a plurality of first differences as a correction parameter;

[0102] subtracting the correction parameter from each of the plurality of radial distance data to obtain corresponding new radial distance data;

[0103] The new radial distance data is compared with the standard radial distance data to obtain a second difference. If the second difference is within a preset error range, it is determined that there is an installation error in the curved rail, and the following sub-steps are entered:

[0104] If the first difference is positive, the first curved rail 11 and the second curved rail 12 are pushed to move toward each other;

[0105] If the first difference is negative, the first curved rail 11 and the second curved rail 12 are pushed to move away from each other;

[0106] After the movement is completed, the curved track setting step, the detection step and the comparison step are repeated until the curved track setting is completed.

[0107] During the assembly process of the curved rails, one curved rail may be offset in a direction away from or close to another curved rail. Specifically, if the first curved rail 11 is offset in a direction away from the second curved rail 12, the first differences between the plurality of radial distance data measured and the standard radial distance data are all positive. If the second curved rail 12 is offset in a direction close to the second curved rail 12, the first differences between the plurality of radial distance data measured and the radial standard radial distance data are all negative.

[0108] Therefore, in this embodiment, if the first difference is outside the preset error range, it is determined that there is an assembly error in the curved rail; if the first differences obtained by subtracting the standard distance data from the multiple sets of radial distance data are all positive or negative, it means that the assembly error of the curved rail may be caused by the deviation of one curved rail in the direction away from or close to another curved rail. Subsequently, by correcting the measured radial distance data, waiting for new radial distance data, and comparing the new radial distance data with the standard radial distance data to obtain a second difference, if the second difference is within the preset error range, it is determined that the assembly error of the curved rail is caused by the deviation of one curved rail in the direction away from or close to another curved rail. Finally, according to the first difference obtained by subtracting the standard distance data from the initial radial distance data, the adjustment method is determined, that is, if the first difference obtained by subtracting the standard distance data from the initial radial distance data is positive, the first curved rail 11 and the second curved rail 12 are pushed to move closer to each other; if the first difference obtained by subtracting the standard distance data from the initial radial distance data is negative, the first curved rail 11 and the second curved rail 12 are pushed to move away from each other. In this way, it is possible to determine whether the curved rail is set up, determine the cause of the curved rail assembly error and the adjustment method through multiple sets of radial distance data measured at one time, thereby greatly improving the assembly efficiency.

[0109] For example, in some embodiments, the measured first radial distance data is 1556.5, the second radial distance data is 1556.2, and the third radial distance data is 1554.9; the standard radial distance data is 1550.0, and the preset error range is ±2. The first difference between the first radial distance data and the standard radial distance data is 6.5, the first difference between the second radial distance data and the standard radial distance data is 6.2, and the first difference between the third radial distance data and the standard radial distance data is 4.9. Since the three first differences (6.5, 6.2, 4.9) are all greater than the preset error range (±2), it is determined that there is an assembly error in the curved track.

[0110] Since the three first differences (6.5, 6.2, 4.9) are all positive, we proceed to the following judgment:

[0111] From the plurality of first differences, a first difference with the smallest absolute value is selected as a correction parameter; that is, among the three first differences (6.5, 6.2, 4.9), 4.9 is the smallest first difference and is used as the correction product;

[0112] Subtract the correction parameter from the plurality of radial distance data to obtain corresponding new radial distance data, that is, the new first radial distance data is 1556.5-4.9=1551.6, the new second radial distance data is 1556.2-4.9=1551.3, and the new third radial distance data is 1554.9-4.9=1550;

[0113] The new radial distance data is compared with the standard radial distance data to obtain the second difference; that is, the second difference corresponding to the new first radial distance data is 1551.6-1550=1.6, the second difference corresponding to the new second radial distance data is 1551.3-1550=1.3, and the second difference corresponding to the new third radial distance data is 1550-1550=0. The three second differences (1.6, 1.3, 0) are all within the preset error range (±2), so it is determined that the assembly error of the curved rail is caused by the deviation of one curved rail in the direction away from or close to the other curved rail;

[0114] Finally, since the three first differences (6.5, 6.2, 4.9) are all positive, the first curved rail 11 and the second curved rail 12 are pushed to move toward each other; after the movement is completed, the curved rail setting step, the detection step and the comparison step are repeated until the curved rail setting is completed.

[0115] It is worth noting that, in this embodiment, the new radial distance data can not only be used to determine whether the assembly error of the curved rail is caused by the deviation of one curved rail in the direction away from or close to another curved rail, but also can be used to determine whether the curved rail meets the processing requirements and confirm the deflection of the curved rail by using the method disclosed in the second embodiment.

[0116] For example, assuming that after the above data correction, the new first radial distance data is 1554.2, the new second radial distance data is 1551.1, and the new third radial distance data is 1549.4, and the corresponding second differences are 4.2, 1.1, and -0.6 respectively; the second difference (4.2) corresponding to the new first radial distance data is outside the preset error range (±2), then continue to judge as follows:

[0117] If the first radial distance data, the second radial distance data and the third radial distance data increase or decrease in sequence; specifically, the new first radial distance data is 1554.2, the new second radial distance data is 1551.1, the new third radial distance data is 1549.4, 1554.2>1551.1>1549.4, the new first radial distance data, the new second radial distance data and the new third radial distance data decrease in sequence, then it is determined that there is an installation error between the first curved rail 11 and the second curved rail 12, and the first curved rail 11 and the second curved rail 12 need to be re-set.

[0118] In this way, it is possible to determine whether the curved track is set up through multiple radial distance data in one measurement; if there is an assembly error in the curved track, multiple judgments can be made through the measured multiple radial distance data to confirm the cause of the curved track assembly error and determine the adjustment method, which greatly improves the assembly efficiency and accuracy.

[0119] Implementation Method 4

[0120] This embodiment is a further improvement based on the first embodiment, the second embodiment and the third embodiment, and the improvement is that a data screening step is added to improve the accuracy of the judgment. Specifically, Figure 1 As shown, before the comparison step, it also includes:

[0121] Data screening step: comparing two sets of radial distance data corresponding to adjacent parts to obtain a third difference value, and if the third difference value is within a preset deviation range, the radial distance data is determined to be qualified;

[0122] Otherwise, it is determined that the radial distance data is invalid, and new radial distance data is remeasured.

[0123] It should be noted that when measuring the radial distance data between the corresponding parts of the first curved rail 11 and the second curved rail 12 at the same circumferential angle, it is easy to be affected by the operation error or the defects of the curved rail itself, thereby causing the measurement data to be inaccurate or the quality to be reduced. Therefore, through this data screening step, the accuracy and reliability of the measured radial distance data can be effectively ensured.

[0124] Specifically, in this embodiment, the surface of the curved rail is relatively smooth and gentle; therefore, the third difference between the two sets of distance data corresponding to adjacent parts is small. If the third difference between the two is greater than the set deviation range, it means that the reliability and accuracy of the two sets of radial distance data are poor and need to be screened out.

[0125] In addition, in some embodiments, the first curved track 11 can be composed of multiple first sub-curved tracks; correspondingly, the second curved track 12 can also be composed of multiple second sub-curved tracks. The smoothness in the sub-curved track and the smoothness at the connection between the two sub-curved tracks are different. Therefore, in the data screening step, different deviation ranges need to be set for the corresponding radial distance data in the sub-curved track and the corresponding radial distance data at the connection between the two sub-curved tracks.

[0126] Specifically, in the data screening step, the preset deviation range includes:

[0127] The curve track deviation range is applicable when the parts corresponding to the two sets of radial distance data are located in the same section of the first sub-curved track;

[0128] The connection deviation range is applicable when a portion corresponding to a set of radial distance data is located at a connection point between two adjacent sections of the first sub-curved rail.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention rather than to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the present invention can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
