Description

Technical Field

[0001] This application relates to photovoltaic manufacturing technology, and more particularly to a method for correcting the deflection of a paddle loaded into a furnace tube and a device for adjusting the paddle deflection. Background Technology

[0002] Large-scale equipment in fields such as photovoltaics or semiconductors often requires the installation and adjustment of boats, propellers, and furnace tubes. Currently, the installation and adjustment process often involves multiple workers: worker A measures the dimensions of each part to be adjusted using measuring tools (e.g., a steel ruler) at one end of the propeller (e.g., the end of the propeller closer to the furnace tube before it enters), while worker B adjusts the installation at the other end of the propeller (e.g., the end of the propeller furthest from the furnace tube). Once worker A's measurements are optimal, feedback is given to worker B, and the adjustment stops. The entire commissioning process is time-consuming, feedback is inefficient, commissioning progress is slow, efficiency is low, and the measured data is difficult to record and integrate into automation. Summary of the Invention

[0003] In view of this, it is necessary to provide a method for correcting the deviation of the paddle when it is loaded into the furnace tube to improve the debugging efficiency.

[0004] Some embodiments of this application provide a method for correcting the alignment of a paddle loaded into a furnace tube, including: The designated position for placing the paddle outside the furnace tube and near the furnace opening; The selected measuring device measures the three coordinate directions of the rectangular coordinate system of the reference: the first direction, the second direction, and the third direction. The paddle enters the furnace tube along the second direction. The measuring device measures the first center of the first end face of the paddle facing the furnace tube, which is parallel to the first direction and the third direction, and measures the second center of the second end face of the furnace tube facing the paddle, which is parallel to the first direction and the third direction. The distance measuring sensor of the measuring device is installed at the first center; The drive propeller moves to the furnace opening of the furnace tube, so that the first center and the second center coincide. The distance H1 between the first center and the wall of the furnace tube along the first direction and the distance H2 along the third direction are measured by the distance sensor and fed back to the host computer. The propeller moves into the furnace tube, and the distance between the first center and the furnace opening along the second direction is d; the distance H1a between the first center and the wall of the furnace tube along the first direction and the distance H2a along the third direction are measured by a distance measuring sensor and fed back to the host computer. The first deflection angle δ relative to the furnace tube along the first direction and the second deflection angle θ relative to the furnace tube along the third direction are calculated using the host computer. The first deflection angle δ satisfies: tanδ=(H1a-H1) / d, and the second deflection angle θ satisfies: tanθ=(H2a-H2) / d. Adjust the first deflection angle δ and the second deflection angle θ to 0 respectively.

[0005] The above-mentioned method for correcting propeller deflection communicates with a host computer through a measuring device. The measuring device measures the actual coordinates of the propeller along the selected three-coordinate direction and feeds the results back to the host computer. The host computer calculates the angle of deflection of the propeller relative to the furnace tube. By adjusting these angles to 0 degrees, the propeller deflection operation relative to the furnace tube can be completed. No manual measurement is required. One person can complete the propeller deflection through the host computer, which is highly efficient.

[0006] According to some embodiments of this application, the step of "measuring the first center of the first surface of the paddle facing one end of the furnace tube, parallel to the first direction and the third direction, using a measuring device" includes: Select a first initial point, and use the first initial point as the origin of the rectangular coordinate system. The first initial point is not located inside the outer contour line of the first end face. The measuring device starts from the first initial point and moves towards the paddle along the first direction, passing the first endpoint and the second endpoint of the contour of the first end face. The distance L01 between the first endpoint and the first initial point along the first direction, and the distance L1 between the first endpoint and the second endpoint along the first direction are measured. The measuring device feeds back L01 and L1 to the host computer. The measuring device moves from the first initial point along a third direction toward the paddle, passing the third and fourth endpoints of the outer contour of the first end face. The distance L02 between the third endpoint and the first initial point along the third direction, and the distance L2 between the third endpoint and the fourth endpoint along the third direction are measured. The measuring device feeds back L02 and L2 to the host computer. The host computer calculates the coordinates of the first center along the first direction and the third direction based on L01, L1, L02 and L2 as (L1+L01 / 2, L2+L02 / 2).

[0007] In the above embodiments, by measuring the first center of the paddle toward the first end face of the furnace tube, it is beneficial for the paddle to be centered with the furnace tube along the first direction and the third direction when it begins to enter the inlet of the furnace tube.

[0008] According to some embodiments of this application, the measuring device passes through the outer contour of the first end face multiple times along the first direction and the third direction to obtain multiple sets of first endpoints and second endpoints, and to obtain multiple coordinate values ​​of the first center along the first direction. The host computer calculates the average coordinate value of the first center along the first direction. The measuring device passes through the outer contour of the first end face multiple times along the third direction to obtain multiple sets of third and fourth endpoints, and to obtain multiple coordinate values ​​of the first center along the third direction. The host computer calculates the average coordinate value of the first center along the third direction.

[0009] In the above embodiments, the average coordinate values ​​of the first center along the first direction and the average coordinate values ​​along the third direction are beneficial to improving the accuracy of the first center position measurement and the accuracy of the relative position of the adjusting paddle and the furnace tube.

[0010] According to some embodiments of this application, the second end face is circular, and the step of "measuring the second center of the second end face of the furnace tube facing the paddle end, which is parallel to the first direction and the third direction" includes: Select a second initial point, and use the second initial point as the origin of the rectangular coordinate system. The second initial point is not located inside the outer contour line of the second end face. The measuring device moves from the second initial point toward the paddle along the first direction and the third direction, and passes through the three endpoints of the outer contour of the second end face. The three endpoints include the fifth endpoint, the sixth endpoint, and the seventh endpoint. The fifth endpoint and the sixth endpoint are arranged along the first direction, and the sixth endpoint and the seventh endpoint are arranged along the third direction. The measuring device measures the distance M01 between the fifth endpoint and the sixth endpoint, which is closer to the second initial point, and the distance M1 between the fifth endpoint and the sixth endpoint along the first direction. The measuring device then feeds back M01 and M1 to the host computer. The measuring device measures the distance M02 between the sixth and seventh endpoints that are closer to the second initial point and the second initial point along the third direction, and the distance M2 between the sixth and seventh endpoints along the third direction. The measuring device then feeds back M02 and M2 to the host computer. The coordinates of the first center along the first direction and the third direction are calculated by the host computer based on M01, M1, M02 and M2 as (M1+M01 / 2, M2+M02 / 2).

[0011] In the above embodiment, by measuring the second center of the paddle toward the second end face of the furnace tube, it is beneficial for the paddle to be centered with the furnace tube along the first direction and the third direction when it begins to enter the tube opening.

[0012] According to some embodiments of this application, the measuring device moves towards the paddle multiple times along the first direction and the third direction, and obtains multiple sets of three endpoints of the outer contour of the second end face. The measuring device measures the coordinates of the multiple sets of three endpoints, and the host computer calculates the average coordinates of the second center along the first direction and the third direction, respectively.

[0013] In the above embodiments, the average coordinate values ​​of the second center along the first direction and the average coordinate values ​​along the third direction are beneficial to improving the accuracy of the second center position measurement and the accuracy of the relative position of the adjusting paddle and the furnace tube.

[0014] According to some embodiments of this application, the ranging sensor is a radar sensor, and the ranging sensor is driven to rotate about an axis parallel to the second direction by a driving structure in the measuring device, so that the ranging sensor can be aligned with the tube wall inside the furnace tube along the first direction and along the third direction.

[0015] In the above embodiments, the ranging sensor is a radar sensor and can rotate, which can adapt to measuring the distance between the first center and the wall of the furnace tube inside the furnace tube, thereby realizing the acquisition of adjustment data.

[0016] According to some embodiments of this application, the propeller is driven to move along the second direction n times to complete the placement of the propeller entirely inside the furnace tube. The distance of each propeller movement is m, where m*n is greater than the length of the propeller corresponding to the second direction. Each of the n movements involves the following steps: "Drive the propeller to move into the furnace tube, with the distance between the first center and the furnace opening along the second direction being d; use a distance measuring sensor to measure the distance H1a between the first center and the wall of the furnace tube along the first direction and the distance H2a along the third direction, and feed it back to the host computer; use the host computer to calculate the first deflection angle δ of the propeller relative to the furnace tube along the first direction and the second deflection angle θ of the propeller relative to the furnace tube along the third direction, where the first deflection angle δ satisfies: tanδ=|H1a-H1| / d, and the second deflection angle θ satisfies: tanθ=|H2a-H2| / d; adjust the first deflection angle δ and the second deflection angle θ to 0 respectively."

[0017] In the above embodiments, the propeller is corrected in each of the nth steps, which further improves the positional accuracy of the propeller relative to the furnace tube along the first direction and the third direction, which is beneficial to the uniform reaction of the components inside the propeller.

[0018] According to some embodiments of this application, before the step of "measuring the first center of the first surface of the paddle facing the furnace tube parallel to the first direction and the third direction using a measuring device", the method further includes correcting the paddle deflection. The step of correcting the paddle deflection includes: To measure the first angle γ of the propeller deflection about an axis parallel to the first direction: Select a first plane on the propeller corresponding to a first theoretical plane parallel to the first and second directions; select two first points arranged along the second direction on the first plane; use a measuring device to measure the coordinate values ​​of the two first points along the second and third directions and feed them back to the host computer; the host computer calculates the distance y1 between the two first points along the second direction and the distance z1 along the third direction, and the first angle γ: tanγ=z1 / y1; To measure the second angle α of the propeller deflection about an axis parallel to the second direction: Select a second plane on the propeller corresponding to the second theoretical plane parallel to the second and first directions. Select two second points on the second plane arranged along the first direction. Use a measuring device to measure the coordinate values ​​of the two second points along the first and third directions and feed them back to the host computer. The host computer calculates the distance x2 between the two second points along the first direction and the distance z2 along the third direction, as well as the second angle α: tanα=z2 / x2; To measure the third angle β of the propeller deflection about an axis parallel to the third direction: Select a third plane on the propeller corresponding to the third theoretical plane parallel to the second and third directions. Select two third points on the third plane arranged along the second direction. Use a measuring device to measure the coordinate values ​​of the two third points along the second and first directions and feed them back to the host computer. The host computer calculates the distance y3 between the two third points along the second direction and the distance x3 along the first direction, and the third angle β: tanβ=x3 / y3. Adjust the position of the propeller so that the first angle γ reaches the first set value, the second angle α reaches the second set value, and the third angle β reaches the third set value.

[0019] In the above embodiments, the propeller is corrected before entering the furnace tube, and then the propeller is loaded into the furnace tube. This helps to reduce the risk of the propeller hitting the tube wall when it enters the furnace tube, and also helps to improve the positional accuracy of the propeller in the furnace tube, thereby helping to improve the uniformity of the reaction of the workpiece carried by the propeller in the furnace tube.

[0020] According to some embodiments of this application, the third direction is the vertical direction, and the second and third set values ​​are 0; the first set value is greater than 0, so that the end of the paddle closer to the furnace tube is higher in the third direction than the end of the paddle farther from the furnace tube.

[0021] In the above embodiment, the end of the paddle near the furnace tube is a suspended end, which is usually unable to provide support. The total weight of the paddle and the components it carries will drive the end of the paddle near the furnace tube to move downward in a third direction relative to the end of the paddle away from the furnace tube. The first set value is greater than 0, and the end of the paddle near the furnace tube is higher than the second end, which helps to counteract the offset of the first end of the paddle descending due to its weight.

[0022] An embodiment of this application also provides a device for adjusting propeller deflection. The device for adjusting propeller deflection, which applies the above-described method for correcting propeller deflection, includes a measuring device and a host computer. The measuring device includes a driving element, a first measuring element, a driving structure, and a distance sensor.The first measuring component includes a first control unit, and a first measuring element, a third measuring element, and a sixth measuring element, which are electrically connected to the first control unit. A drive unit is configured to drive the first measuring element to move from a first initial point along a first direction toward the propeller, passing successively through the first endpoint and the second endpoint of the outer contour of the first end face, and measuring the distance L01 between the first endpoint and the first initial point along the first direction, and the distance L1 between the first endpoint and the second endpoint along the first direction, respectively. The third measuring element feeds back L01 and L1 to the host computer through the first control unit. The drive unit also drives the third measuring element to move from the first initial point along a third direction toward the propeller, passing successively through the third endpoint and the fourth endpoint of the outer contour of the first end face, and measuring the distance L01 between the third endpoint and the first initial point. The distance L02 from the starting point along the third direction, and the distances L2 from the third and fourth endpoints along the third direction, are fed back to the host computer by the first control unit. The host computer calculates the coordinates of the first center along the first direction and the third direction as (L1+L01 / 2, L2+L02 / 2) based on L01, L1, L02, and L2. The driving unit drives the sixth measuring element to move from the second initial point towards the propeller along the first direction and the third direction, and passes through the three endpoints of the outer contour of the second end face. The three endpoints include the fifth endpoint, the sixth endpoint, and the seventh endpoint. The fifth endpoint and the sixth endpoint are arranged along the first direction, and the sixth endpoint and the seventh endpoint are arranged along the third direction. The sixth measuring element measures the first... The distances M01 between the fifth endpoint and the second initial point along the first direction, and the distances M1 between the fifth and sixth endpoints along the first direction, are fed back to the host computer via the first control unit. The sixth measuring element measures the distances M02 between the sixth endpoint and the second initial point along the third direction, and the distances M2 between the sixth and seventh endpoints along the third direction, and feeds back M02 and M2 to the host computer via the first control unit. The host computer calculates the coordinates of the first center along the first and third directions as (M1+M01 / 2, M2+M02 / 2) based on M01, M1, M02, and M2. The distance sensor is installed at the first center, and the driving structure drives the distance sensor to rotate around an axis parallel to the second direction, enabling the distance sensor to... The distance sensor measures the distance H1 between the first center and the wall of the furnace tube along the first direction and the distance H2 along the third direction, and feeds it back to the host computer. When the propeller moves into the furnace tube and the distance d between the first center and the furnace opening along the second direction is d, the distance sensor measures the distance H1a between the first center and the wall of the furnace tube along the first direction and the distance H2a along the third direction, and feeds it back to the host computer. The host computer calculates the first deflection angle δ of the propeller relative to the furnace tube along the first direction and the second deflection angle θ of the propeller relative to the furnace tube along the third direction. The first deflection angle δ satisfies: tanδ=(H1a-H1) / d, and the second deflection angle θ satisfies: tanθ=(H2a-H2) / d.

[0023] The aforementioned device for adjusting the paddle deflection measures the first center of the first end face of the paddle, the second center of the second end face of the furnace tube, the distance between the first center and the tube wall at the tube opening, and the distance between the first center and the tube wall when it enters the furnace tube at a distance d. The upper computer calculates the deflection angle of the paddle relative to the furnace tube: the first deflection angle δ and the second deflection angle θ. The adjustment ends when the value of the deflection angle becomes 0 during the paddle adjustment process, thus completing the correction of the paddle relative to the furnace tube.

Detailed Implementation

[0040] The implementation of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Please see Figure 1 , Figure 2 and Figure 3One embodiment of this application proposes a method for correcting the alignment of a paddle when it is inserted into a furnace tube. This method can reduce the risk of the paddle 400 colliding with the structure inside the furnace tube 500 during its entry into the furnace tube 500. For example, the structure inside the furnace tube 500 may be the tube wall of the furnace tube 500 or the structure that provides the reaction inside the furnace tube 500. In addition, it also helps to improve the uniformity of the position arrangement of the paddle 400 inside the furnace tube 500, thereby improving the reaction uniformity of the components inside the paddle 400.

[0044] The propeller deflection adjustment device 300 includes a measuring device 100 and a host computer 200. The measuring device 100 is used to measure data of the propeller 400 and the furnace tube 500. The measuring device 100 and the host computer 200 are electrically connected, and the operator can use the host computer 200 to know the rotation status of the propeller 400 and the deflection status of the propeller 400 relative to the furnace tube 500, and perform correction operations on the propeller 400 accordingly.

[0045] The host computer 200 can be a mobile terminal, workstation all-in-one machine, handheld computer or other structure that can interact with data, and can control the measuring device 100 to measure the paddle 400 and furnace tube 500.

[0046] Methods for correcting propeller 400° deflection include: S10: Install propeller 400 to the set position.

[0047] The propeller 400 is initially installed at a set position, and measurements are taken at that set position.

[0048] In one embodiment, the designated location is outside the furnace tube 500 and close to the opening 501 of the furnace tube 500, but it is not limited to this. For example, in other embodiments, the designated location may also be a designated space for the propeller 400 correction operation, such as a space parallel to the furnace tube 500.

[0049] S20: Select the three coordinate directions of the rectangular coordinate system of the measurement reference 100: the first direction Y, the second direction X, and the third direction Z.

[0050] The three-coordinate system can be set according to the position of the paddle 400 inside the furnace tube 500. For example, when the paddle 400 is installed horizontally into the furnace tube 500 and remains approximately horizontal, the third direction Z in the three-coordinate system is the vertical direction, the second direction X is the direction in which the paddle 400 enters the furnace tube 500, and the second direction X, the first direction Y, and the third direction Z are all perpendicular to each other. The first direction Y is the width direction of the paddle 400, the second direction X is the length direction of the paddle 400, and the third direction Z is the height direction of the paddle 400.

[0051] It is understood that in other embodiments, when the paddle 400 is tilted within the furnace tube 500, the plane determined by the first direction Y and the second direction X can be set to be parallel to the tilting direction of the paddle 400 within the furnace tube 500.

[0052] S30: Corrects propeller deflection at 400 degrees.

[0053] Before the paddle 400 enters the furnace tube 500, the paddle 400 is corrected and then loaded into the furnace tube 500. This helps to reduce the risk of the paddle 400 hitting the tube wall when it enters the furnace tube 500, and also helps to improve the positional accuracy of the paddle 400 in the furnace tube 500. This, in turn, helps to improve the uniformity of the reaction of the workpiece carried by the paddle 400 in the furnace tube 500.

[0054] The theoretical position of the propeller 400 in the three coordinate directions is as follows: Figure 4 As shown, for the convenience of explaining the positional changes of the propeller 400 later, the propeller 400 is simplified to a roughly rectangular columnar structure. It can be understood that this application does not limit the actual shape of the propeller 400.

[0055] No correction is needed when the actual position of propeller 400 matches the theoretical position. Correction is required when the actual position of propeller 400 does not match the theoretical position.

[0056] S31: Measure the first angle γ of the deflection of the propeller 400 about an axis parallel to the first direction Y.

[0057] like Figure 5 As shown, a first plane S1 is selected on the propeller 400 corresponding to a first theoretical plane T1 parallel to the first direction Y and the second direction X. The first theoretical plane T1 is parallel to the first direction Y and the second direction X. In one embodiment, the first plane S1 corresponding to the propeller 400 and the first theoretical plane T1 is the upper surface of the propeller 400, which is a plane, but it is not limited to this. For example, the first plane S1 can also be a partial plane of the upper surface of the propeller 400.

[0058] No correction is needed when the first plane S1 is coplanar or parallel to the first theoretical plane T1; correction is needed when the first plane S1 is not coplanar with the first theoretical plane T1.

[0059] Two first points P1 are selected on the first plane S1, arranged along the second direction X. A measuring device 100 measures the coordinates of the two first points P1 along the second direction X and the third direction Z. The measuring device 100 feeds back the coordinates of the two first points P1 to the host computer 200. The host computer 200 calculates the distance y1 between the two first points P1 along the second direction X and the distance z1 along the third direction Z. The first angle γ satisfies: tanγ = z1 / y1. The host computer 200 can then calculate the first angle γ of the propeller 400's deflection about an axis parallel to the first direction Y.

[0060] Please see Figure 3The measuring device 100 includes a drive unit 10, a first measuring component 20, and a second measuring component 30. The first measuring component 20 and the second measuring component 30 are respectively disposed on the drive unit 10. The first measuring component 20 includes a first control unit 21 and a first measuring element 23. The first measuring element 23 is electrically connected to the first control unit 21 to feed back measurement data to the first control unit 21. The first control unit 21 is electrically connected to a host computer 200, and the host computer 200 sends instructions to the first control unit 21, which then controls the first measuring element 23 to measure the propeller 400. The second measuring component 30 includes a second control unit 31 and a fifth measuring element 35. The fifth measuring element 35 is electrically connected to the second control unit 31 to feed back measurement data to the second control unit 31. The second control unit 31 is also electrically connected to the host computer 200, which sends instructions to the second control unit 31, which then controls the fifth measuring element 35 to measure the propeller 400.

[0061] In one embodiment, the first control unit 21 and the second control unit 31 are both microcontrollers, and the first measuring element 23 and the fifth measuring element 35 are laser displacement sensors, but are not limited thereto. For example, in other embodiments, the first measuring element 23 and the fifth measuring element 35 may also be photoelectric encoders.

[0062] Please combine Figure 3 and Figure 5 As shown, step S31 includes: Step S311: Drive the first measuring element 23 and the fifth measuring element 35 to move relative to the first plane S1 using the driving element 10, and make the distance between the first measuring element 23 and the fifth measuring element 35 along the second direction X be y1.

[0063] In one embodiment, the driving member 10 can move the first measuring member 23 and the fifth measuring member 35 to a position with a spacing of y1 along the second direction X before measurement, and fix the first measuring member 23 and the fifth measuring member 35 in that position. It is understood that in other embodiments, the measuring device 100 may also use the driving member 10 to move the first measuring member 23 and the fifth measuring member 35 to that position during the measurement process.

[0064] Step S312: The first measuring element 23 uses a beam to shoot at one of the two first points P1 along the third direction Z to obtain the coordinates of the first point P1 along the third direction Z, and feeds them back to the host computer 200 through the first control unit 21.

[0065] Step S313: The fifth measuring element 35 uses a beam along the path of the third direction Z to shoot at the other of the two first points P1 to obtain the coordinates of the first point P1 along the third direction Z, and feeds them back to the host computer 200 through the second control unit 31.

[0066] In one embodiment, the first measuring component 20 and the second measuring component 30 are approximately located at both ends of the propeller 400 along the second direction X, and the two first points P1 on the first plane S1 are approximately located at both ends of the propeller 400 along the second direction X, which helps to reduce the error of the coordinate difference between the two first points P1.

[0067] Step S314: Use the host computer 200 to calculate the distance z1 between the two first points P1 along the third direction Z.

[0068] The measuring device 100 emits beams toward the first plane S1 through the first measuring element 23 and the fifth measuring element 35, respectively, and can measure the coordinates of the two first points P1 and feed them back to the host computer 200. The host computer 200 can obtain the distance z1 between the two first points P1 along the third direction Z based on the coordinates of the two first points P1. The third direction Z is perpendicular to the second direction X. The ratio of the distance z1 in the third direction Z to y1 in the second direction X is the tangent of the first angle γ of the propeller 400 deflecting around the axis parallel to the first direction Y. Based on this, the host computer 200 can calculate the first angle γ.

[0069] S32: Measure the second angle α of the deflection of the propeller 400 about an axis parallel to the second direction X.

[0070] like Figure 6 As shown, a second plane S2 is selected on the propeller 400 corresponding to a second theoretical plane T2 parallel to the first direction Y and the second direction X. Two second points P2 arranged along the first direction Y are selected on the second plane S2. The second theoretical plane T2 runs in the first direction Y and the second direction X. In one embodiment, the second plane S2 corresponding to the propeller 400 and the second theoretical plane T2 is the upper surface of the propeller 400, that is, the first plane S1 and the second plane S2 are the same plane, but it is not limited to this. For example, in other embodiments, the first plane S1 and the second plane S2 can be local planes at two positions of the propeller 400.

[0071] The first plane S1 and the second plane S2 are coplanar. When measuring the first angle γ and the second angle α, the measuring device 100 measures points on the same plane. The measuring device 100 saves the step of changing positions, saves time, and thus improves measurement efficiency.

[0072] The measuring device 100 measures the coordinates of two second points P2 along the first direction Y and the third direction Z. The measuring device 100 feeds back the coordinates of the two second points P2 to the host computer 200. The host computer 200 calculates the distance x2 between the two second points P2 along the first direction Y and the distance z2 along the third direction Z. The first direction Y is perpendicular to the third direction Z, and the second angle α satisfies: tanα=z2 / x2. The host computer 200 can calculate the second angle α of the propeller 400 deflection about the axis of the second direction X.

[0073] Please see Figure 3 The first measuring component 20 also includes a second measuring element 25. The first measuring element 23 and the second measuring element 25 are respectively electrically connected to the first control unit 21 to feed back the measurement data to the first control unit 21. The host computer 200 sends instructions to the first control unit 21, and the first control unit 21 controls the first measuring element 23 and the second measuring element 25 to measure the propeller 400.

[0074] In one embodiment, the first measuring element 23 and the second measuring element 25 are beam displacement sensors, but are not limited thereto. For example, in other embodiments, the first measuring element 23 and the second measuring element 25 may also be photoelectric encoders.

[0075] Please see Figure 3 and Figure 6 Step S32 includes: S321: The first measuring element 23 and the second measuring element 25 are moved to be opposite to the second plane S2 by the driving element 10, and the distance between the first measuring element 23 and the second measuring element 25 along the first direction Y is x2.

[0076] S322: The first measuring element 23 uses a beam to shoot at one of the two second points P2 along the third direction Z, obtains the coordinate value of the second point P2 along the third direction Z, and feeds it back to the host computer 200 through the first control unit 21.

[0077] S323: The second measuring element 25 uses a beam along the path of the third direction Z to shoot at the other of the two second points P2 to obtain the coordinate value of the second point P2 along the third direction Z, and feeds it back to the host computer 200 through the first control unit 21. S324: The distance z2 between the two second points P2 is calculated using the host computer 200.

[0078] Steps S42 and S43 can be performed simultaneously. The distance between the first measuring element 23 and the second measuring element 25 can be fixed along the first direction Y, as long as the distance x2 between the first measuring element 23 and the second measuring element 25 along the first direction Y is less than the width of the paddle 400, so that the two second points P2 are on the second plane S2.

[0079] In another embodiment, steps S42 and S43 may not be performed simultaneously. For example, the driving member 10 is further configured to drive the second measuring member 25 to move from the first measuring member 23 along the first direction Y, and the distance that the second measuring member 25 moves relative to the first measuring member 23 along the first direction Y is the spacing x2.

[0080] The drive unit 10 can drive the second measuring unit 25 to move relative to the first measuring unit 23. That is, the drive unit 10 drives the second measuring unit 25 and the first measuring unit 23 to move to different distances, which is beneficial to adapt to the size changes of the propeller 400 along the first direction Y. For example, the measuring device 100 can adapt to measuring the propeller 400 with different sizes along the first direction Y.

[0081] The measuring device 100 emits beams toward the second plane S2 through the first measuring element 23 and the second measuring element 25 respectively, and can measure the coordinates of the two second points P2 and feed them back to the host computer 200. The host computer 200 can obtain the distance z2 between the two second points P2 along the third direction Z based on the coordinates of the two second points P2. The third direction Z is perpendicular to the first direction Y. The ratio of the distance z2 in the third direction Z to x2 in the first direction Y is the tangent of the second angle α of the propeller 400 deflecting around the axis parallel to the second direction X. Based on this, the host computer 200 can calculate the second angle α.

[0082] In one embodiment, the first point P1 and the second point P2 of the first plane S1 measured by the first measuring element 23 are the same point, so the first measuring element 23 does not need to change its position, thus improving the measurement efficiency.

[0083] S33: Measure the third angle β of the propeller 400 deflection about an axis parallel to the third direction Z.

[0084] like Figure 7 As shown, a third plane S2 is selected on the propeller 400, corresponding to a third theoretical plane T3 parallel to the second direction X and the third direction Z. In one embodiment, the third plane S2 is the side surface of the propeller 400. Two third points P3 arranged along the second direction X on the third plane S2 are selected. The coordinate values ​​of the two third points P3 along the second direction X and the first direction Y are measured using a measuring device 100. The measuring device 100 feeds back the coordinates of the two third points P3 to the host computer 200. The host computer 200 calculates the distance y3 between the two third points P3 along the second direction X and the distance x3 along the first direction Y. The third angle β satisfies: tanβ=x3 / y3, and the host computer 200 can calculate the third angle β.

[0085] Please see Figure 3 The first measuring component 20 further includes a third measuring element 27. The third measuring element 27 is electrically connected to the first control unit 21; the second measuring component 30 further includes a fourth measuring element 33. The fourth measuring element 33 is electrically connected to the second control unit 31. The host computer 200 sends instructions to the first control unit 21, and the first control unit 21 controls the third measuring element 27 to measure the propeller 400. The host computer 200 sends instructions to the second control unit 31, and the second control unit 31 controls the fourth measuring element 33 to measure the propeller 400.

[0086] Please see Figure 3 and Figure 7 Step S33 includes: S331: The third measuring element 27 and the fourth measuring element 33 are moved to be opposite to the third plane S2 by the driving element 10, and the distance between the third measuring element 27 and the fourth measuring element 33 along the second direction X is y3.

[0087] S332: The third measuring element 27 uses a beam to shoot at one of the two third points P3 along the path of the first direction Y to obtain the coordinates of the third point P3 along the first direction Y, and feeds them back to the host computer 200 through the first control unit 21.

[0088] S333: The fourth measuring element 33 uses a beam to shoot along the path of the first direction Y to the other of the two third points P3, so as to obtain the coordinates of the third point P3 along the first direction Y, and feeds them back to the host computer 200 through the second control unit 31.

[0089] S334: The distance x3 between the two third points P3 is calculated using the host computer 200.

[0090] The measuring device 100 emits beams toward the third plane S2 through the third measuring element 27 and the fourth measuring element 33, respectively, and can measure the coordinates of the two third points P3 and feed them back to the host computer 200. The host computer 200 can obtain the distance x3 between the two second points P2 along the first direction Y based on the coordinates of the two third points P3. The second direction X is perpendicular to the first direction Y. The ratio of the distance x3 in the first direction Y to the y3 in the first direction Y is the tangent of the third angle β of the propeller 400 deflecting around the axis parallel to the third direction Z. Based on this, the host computer 200 can calculate the third angle β of the propeller 400 deflecting around the axis parallel to the third direction Z.

[0091] Steps S312 to S313, S322 to S323, and S332 to S333 can be performed simultaneously or in any order; this application does not impose any restrictions on this.

[0092] S34: Adjust the position of the propeller 400 so that the second angle α reaches the second set value, the first angle γ reaches the first set value, and the third angle β reaches the third set value.

[0093] It is understood that in other embodiments, the position of the paddle 400 can be adjusted after the first angle γ is measured so that the first angle γ reaches the first set value.

[0094] It is understood that in other embodiments, the position of the paddle 400 can be adjusted after the second angle α is measured so that the second angle α reaches the second set value.

[0095] It is understood that in other embodiments, the position of the paddle 400 can be adjusted after the third angle β is measured so that the third angle β reaches the third set value.

[0096] It is understood that in other embodiments, the propeller 400 can be adjusted to move or rotate in different directions so that the position of the propeller 400 simultaneously satisfies the following conditions: the first angle γ reaches the first set value, the second angle α reaches the second set value, and the third angle β reaches the third set value.

[0097] In one embodiment, the second and third set values ​​are 0. The first set value is greater than 0, so that the end of the paddle 400 closer to the furnace tube 500 is higher in the third direction Z than the end of the paddle 400 farther from the furnace tube 500.

[0098] The paddle 400 has a first end 401 and a second end 402 along the second direction X. The first end 401 is the end of the paddle 400 closer to the furnace tube 500, and the second end 402 is the end of the paddle 400 farther from the furnace tube 500. The first end 401 of the paddle 400 is a suspended end and is normally unable to provide support. The total weight of the paddle 400 and the components it carries will drive the second end 402 of the paddle 400 to move downwards along the third direction Z relative to the first end 401 of the paddle 400. A first set value greater than 0 indicates that the first end 401 of the paddle 400 is higher than the second end 402, which helps to counteract the offset caused by the weight of the paddle 400 causing the first end 401 to descend.

[0099] To further improve the measurement accuracy of the measuring device 100, the measuring device 100 measures multiple first angles to obtain the average value of the first angles, measures multiple second angles to obtain the average value of the second angles, and measures multiple third angles to obtain the average value of the third angles.

[0100] Multiple sets of coordinate values ​​can be obtained by selecting multiple parallel planes: For example, in one embodiment, in step S30, a plurality of first planes S1 are selected, two first points P1 are selected on each first plane S1, and the average value of a plurality of first angles derived from the first points P1 on the plurality of first planes S1 is adjusted. Return to the first set value.

[0101] For example, in step S40, multiple second planes S2 are selected, and two second points P2 are selected on each second plane S2. The average value of multiple second angles obtained from the second points P2 on the multiple second planes S2 is adjusted. To the second set value.

[0102] For example, in step S50, multiple third planes S2 are selected, and two third points P3 are selected on each third plane S2. The average value of multiple third angles obtained from the third points P3 on the multiple third planes S2 is adjusted. Up to the third setting value.

[0103] Alternatively, by selecting more than two points in the same plane and measuring the coordinates of multiple points, multiple sets of coordinate values ​​can be obtained.

[0104] For example, in step S31, multiple first points P1 arranged along the second direction X on the first plane S1 are selected, a first angle is obtained based on the distance between every two first points P1, and the average value of the multiple first angles is adjusted. Return to the first set value.

[0105] For example, in step S32, multiple second points P2 arranged along the first direction Y on the second plane S2 are selected, and a second angle is obtained based on the distance between every two second points P2. The average value of the multiple second angles is then adjusted. To the second set value.

[0106] For example, in step S33, multiple third points P3 arranged along the second direction X on the third plane S2 are selected, and a third angle is obtained based on the distance between every two third points P3. The average value of the multiple third angles is then adjusted. Up to the third setting value.

[0107] It is understood that the selection of planes and points depends on the structure of different propellers 400, and this application does not limit this.

[0108] It is understood that in other embodiments, multiple paddles 400 can be installed simultaneously within the same furnace tube 500. The measuring device 100 measures each paddle 400 in approximately the same direction. The first measuring component 20 and the second measuring component 30 are moved to the position corresponding to the paddle 400 to be measured by the driving component 10. In another embodiment, two paddles 400 are arranged along the first direction Y and installed within the same furnace tube 500. The driving component 10 drives the measuring device 100 to be positioned on the side of one paddle 400 away from the other paddle 400. After the measuring device 100 has measured one paddle 400, the driving component 10 drives the measuring device 100 to move to the side of the other paddle 400 away from it, or above the other paddle 400, to measure the other paddle 400.

[0109] The above-mentioned method for correcting the deflection of the propeller 400 is achieved by communicating with the host computer 200 through the measuring device 100. The measuring device 100 measures the actual coordinates of the propeller 400 along the selected three-coordinate direction and feeds them back to the host computer 200. The host computer 200 calculates the angle of deflection of the propeller 400 around the axis parallel to the three-coordinate direction. By adjusting these angles to the set values, the deflection correction of the propeller 400 can be completed. No manual measurement is required. One person can complete the deflection correction of the propeller 400 through the host computer 200, which is highly efficient.

[0110] In addition, the measuring device 100 uses a beam to illuminate the paddle 400 for measurement, which has a higher measurement accuracy than that of ordinary measuring tools used manually, thus improving the positional accuracy of the paddle 400.

[0111] Please continue reading. Figure 1 S40: The measuring device 100 measures the first center O1 of the first end face A1 of the measuring paddle 400 facing the furnace tube 500, which is parallel to the first direction Y and the third direction Z.

[0112] like Figure 3 and Figure 4 As shown, in one embodiment, the first end face A1 is the side of the paddle 400 facing the furnace tube 500, and this side face is a plane parallel to the first direction Y and the third direction Z. It can be understood that in other embodiments, when the side face of the paddle 400 is not parallel to the first direction Y or the third direction Z, or when the side face is not a plane, the first end face A1 can be a virtual plane passing through the point of the paddle 400 closest to the furnace tube 500 along the second direction X.

[0113] In one embodiment, the first center O1 of the propeller 400 is determined based on the shape of the first end face A1 of the propeller 400. For example, when the first end face A1 of the propeller 400 is square, the first center O1 of the propeller 400 is the intersection of the two diagonals of the square, that is, the center point of the square. The first center O1 is the intersection of two axes; for example, the intersection of the two axes of symmetry passing through the center of the square is the center of the square itself. One of the two axes is parallel to the first direction Y and passes through the first center O1, and the distance between the first center O1 and the intersection point of the first axis along the first direction Y with the outer contours of the two sides of the propeller 400 is equal; the other of the two axes is parallel to the third direction Z and passes through the first center O1, and the distance between the first center O1 and the intersection point of the first axis along the third direction Z with the outer contours of the two sides of the propeller 400 is equal.

[0114] Please see Figure 8 For example, when the first end face A1 of the propeller 400 is a trapezoid symmetrical about an axis parallel to the third direction Z, the intersection of the two axes is the first center O1, and one of the two axes is the centerline of the trapezoid parallel to the first direction Y, as shown below. Figure 8As shown by the dashed lines, the distance between the first center O1 and the intersection point of the axis along the first direction Y with the outer contours of both sides of the propeller 400 is equal; the other axis is the centerline of the trapezoid parallel to the third direction Z, which is also the axis of symmetry of the trapezoid, and the distance between the first center O1 and the intersection point of the axis along the third direction Z with the outer contours of both sides of the propeller 400 is equal.

[0115] When there are multiple propellers 400, the outer contour of each propeller 400 is set to the outermost outer contour of all propellers 400. For example, as Figure 9 As shown, there are two propellers 400, and the two propellers 400 enter the same furnace tube 500. The outermost outline of the two propellers 400 is a rectangle, that is, the first end face A1 is a rectangle. The two diagonals of the rectangle are shown as dashed lines, and the intersection of the two diagonals of the rectangle is the first center O1 of the first end face A1.

[0116] Step S40 includes: S41: Select a first initial point A01, with the first initial point A01 as the origin of the rectangular coordinate system. The first initial point A01 is not located inside the outer contour line of the first end face A1.

[0117] The first initial point A01 can be located on the outer contour line of the first end face A1, or it can be a point on the extended surface outside the first end face A1 of the propeller 400.

[0118] It is understood that in other embodiments, the first initial point A01 can be set within the first end face A1, and the measuring device 100 can move in two opposite directions to measure a set of endpoints (the first endpoint A11 and the second endpoint A12 are a set, and the third endpoint A13 and the fourth endpoint A14 are a set).

[0119] The first initial point A01 is not located inside the outline of the first end face A1, which is beneficial for the measuring device 100 to move in one direction from the first initial point A01 without reciprocating, saving the movement time for measurement and thus improving the measurement efficiency.

[0120] S42: Please refer to Figure 8 and Figure 9 Taking two propellers 400 as an example, this section describes how to determine the first center O1. A measuring device 100 starts from the first initial point A01 and moves along the first direction Y towards the propeller 400, passing successively the first endpoint A11 and the second endpoint A12 of the contour of the first end face A1. The distance L01 between the first endpoint A11 and the first initial point A01 along the first direction Y, and the distance L1 between the first endpoint A11 and the second endpoint A12 along the first direction Y are measured. The measuring device 100 then feeds back L01 and L1 to the host computer 200.

[0121] The driving component 10 is configured to drive the first measuring component 23 to move from the first initial point A01 along the first direction Y toward the propeller 400, and pass through the first endpoint A11 and the second endpoint A12 of the outer contour of the first end face A1. The coordinates of the first endpoint A11 and the second endpoint A12 are measured. The distance L01 between the first endpoint A11 and the first initial point A01 along the first direction Y and the distance L1 between the first endpoint A11 and the second endpoint A12 along the first direction Y are calculated from the coordinates of the first endpoint A11 and the second endpoint A12. The third measuring component 27 feeds back L01 and L1 to the host computer 200 through the first control unit 21.

[0122] S43: The measuring device 100 moves from the first initial point A01 along the third direction Z toward the propeller 400, and passes through the third endpoint A13 and the fourth endpoint A14 of the outer contour of the first end face A1. The measuring device 100 measures the distance L02 between the third endpoint A13 and the first initial point A01 along the third direction Z, and the distance L2 between the third endpoint A13 and the fourth endpoint A14 along the third direction Z. The measuring device 100 feeds back L02 and L2 to the host computer 200.

[0123] In one embodiment, the second endpoint A12 and the third endpoint A13 coincide, but this is not the only embodiment. For example, in other embodiments, when the first end face A1 is square, the third endpoint A13 and the fourth endpoint A14 can also be non-end positions of the first end face A1 along the first direction Y, that is, any position between the two ends of the first end face A1 along the first direction Y.

[0124] The driving component 10 drives the third measuring component 27 to move from the first initial point A01 along the third direction Z toward the propeller 400, and successively passes the third endpoint A13 and the fourth endpoint A14 of the outer contour of the first end face A1. The third measuring component 27 measures the distance L02 between the third endpoint A13 and the first initial point A01 along the third direction Z, and the distance L2 between the third endpoint A13 and the fourth endpoint A14 along the third direction Z. The third measuring component 27 feeds back L02 and L2 to the host computer 200 through the first control unit 21.

[0125] S44: The host computer 200 calculates the coordinates of the first center O1 along the first direction Y and the third direction Z based on L01, L1, L02 and L2 as (L1+L01 / 2, L2+L02 / 2).

[0126] It is understood that in other embodiments, the measuring device 100 traverses the outer contour of the first end face A1 multiple times along the first direction Y and the third direction Z to obtain multiple sets of first endpoints A11 and second endpoints A12, thereby obtaining multiple coordinate values ​​of the first center O1 along the first direction Y. The host computer 200 calculates the average coordinate value of the first center O1 along the first direction Y. The measuring device 100 traverses the outer contour of the first end face A1 multiple times along the third direction Z to obtain multiple sets of third endpoints A13 and fourth endpoints A14, thereby obtaining multiple coordinate values ​​of the first center O1 along the third direction Z. The host computer 200 calculates the average coordinate value of the first center O1 along the third direction Z.

[0127] The average coordinate values ​​of the first center O1 along the first direction Y and the average coordinate values ​​along the third direction Z are beneficial to improving the accuracy of the position measurement of the first center O1 and the accuracy of the relative position of the regulating paddle 400 and the furnace tube 500.

[0128] Please see Figure 10 S50: The measuring device 100 measures the second center O2 of the second end face A2 of the furnace tube 500 facing the paddle 400, which is parallel to the first direction Y and the third direction Z.

[0129] The second end face A2 is the side of the furnace tube 500 facing the paddle 400. The furnace tube 500 is roughly a circular tubular structure, and the second end face A2 of the furnace tube 500 is the circular surface formed by the outer contour of the furnace tube 500 with the largest diameter, and the second center O2 is the center of the circle. It can be understood that when the furnace tube 500 is other shapes, the second end face A2 of the furnace tube 500 is the corresponding shape. For example, when the furnace tube 500 is square, the second center O2 of the furnace tube 500 is the intersection of the diagonals of the square, that is, the center of the square.

[0130] The measuring device 100 also includes a sixth measuring element 28. Step S50 includes: S51: Select a second initial point A02, with the second initial point A02 as the origin of the rectangular coordinate system. The second initial point A02 is not located inside the outer contour line of the second end face A2.

[0131] The second initial point A02 can be located on the outer contour surface of the second end face A2. The second initial point A02 can also be located on the extended surface outside the second end face A2.

[0132] S52: The measuring device 100 starts from the second initial point A02 and moves towards the propeller 400 along the first direction Y and the third direction Z, and passes through the three endpoints of the outer contour of the second end face A2. The three endpoints include the fifth endpoint A21, the sixth endpoint A22, and the seventh endpoint A23. The fifth endpoint A21 and the sixth endpoint A22 are arranged along the first direction Y, and the sixth endpoint A22 and the seventh endpoint A23 are arranged along the third direction Z.

[0133] The driving component 10 drives the sixth measuring component 28 to move from the second initial point A02 along the first direction Y and the third direction Z toward the propeller 400, and passes through the three endpoints of the outer contour of the second end face A2. The three endpoints include the fifth endpoint A21, the sixth endpoint A22, and the seventh endpoint A23. The fifth endpoint A21 and the sixth endpoint A22 are arranged along the first direction Y, and the sixth endpoint A22 and the seventh endpoint A23 are arranged along the third direction Z.

[0134] In one embodiment, the position of the measuring device 100 along the contour of the second end face A2 depends on the position of the second initial point A02. The measuring device 100 starts from the first initial point A01 and passes through the seventh endpoint A23, the sixth endpoint A22, and the fifth endpoint A21 in sequence. When the position of the second initial point A02 changes, the measuring device 100 can also start from the second initial point A02 and pass through the fifth endpoint A21, the sixth endpoint A22, and the seventh endpoint A23 in sequence, and the positions of the fifth endpoint A21, the sixth endpoint A22, and the seventh endpoint A23 can also be changed.

[0135] S53: The measuring device 100 measures the distance M01 between the fifth endpoint A21 and the sixth endpoint A22 that is closer to the second initial point A02 along the first direction Y, and the distance M1 between the fifth endpoint A21 and the sixth endpoint A22 along the first direction Y. The measuring device 100 feeds back M01 and M1 to the host computer 200.

[0136] In one embodiment, the sixth endpoint A22 and the second initial point A02 are arranged along the third direction Z. Therefore, the third direction Z is perpendicular to the first direction Y, and the distance M01 between the sixth endpoint A22 and the second initial point A02 along the first direction Y is 0.

[0137] The sixth measuring element 28 measures the distance M01 between the fifth endpoint A21 and the sixth endpoint A22 that is closer to the second initial point A02 and the distance M1 between the fifth endpoint A21 and the sixth endpoint A22 along the first direction Y, and feeds back M01 and M1 to the host computer 200 through the first control unit 21.

[0138] S54: The measuring device 100 measures the distance M02 between the sixth endpoint A22 and the seventh endpoint A23 that is closer to the second initial point A02 along the third direction Z, and the distance M2 between the sixth endpoint A22 and the seventh endpoint A23 along the third direction Z. The measuring device 100 feeds back M02 and M2 to the host computer 200.

[0139] The sixth measuring element 28 measures the distance M02 between the seventh endpoint A23 and the second initial point A02 along the third direction Z, and the distance M2 between the sixth endpoint A22 and the seventh endpoint A23 along the third direction Z, and feeds back M02 and M2 to the host computer 200 through the first control unit 21.

[0140] S55: Using the host computer 200, the coordinates of the first center O1 along the first direction Y and the third direction Z are calculated as (M1+M01 / 2, M2+M02 / 2) based on M01, M1, M02 and M2.

[0141] It is understood that in other embodiments, the measuring device 100 moves along the first direction Y and the third direction Z towards the paddle 400 multiple times and obtains multiple sets of three endpoints passing through the outer contour of the second end face A2. The measuring device 100 measures the coordinates of the multiple sets of three endpoints, and the host computer 200 calculates the average coordinates of the second center O2 along the first direction Y and the third direction Z respectively.

[0142] The average coordinate values ​​of the second center O2 along the first direction Y and the average coordinate values ​​along the third direction Z are beneficial to improving the accuracy of the position measurement of the second center O2 and the accuracy of the relative position of the regulating paddle 400 and the furnace tube 500.

[0143] S60: Drive the propeller 400 to move to the furnace opening of the furnace tube 500, so that the first center O1 and the second center O2 coincide.

[0144] like Figure 11 As shown, the first center O1 and the second center O2 coincide, so that the distances of the first center O1 and the second center O2 from the wall of the furnace tube 500 are the same.

[0145] In one embodiment, the measuring device 100 further includes a drive structure 22 and a ranging sensor 29.

[0146] S70: Install the ranging sensor 29 of the measuring device 100 at the first center O1.

[0147] The drive structure 22 is mounted on the paddle 400 and can drive the distance sensor 29 to rotate about an axis parallel to the second direction X, so that the distance sensor 29 can be aligned with the tube wall of the furnace tube 500.

[0148] In one embodiment, the ranging sensor 29 is a radar sensor. The driving structure 22 in the measuring device 100 drives the ranging sensor 29 to rotate about an axis parallel to the second direction X, so that the ranging sensor 29 can be aligned with the tube wall inside the furnace tube 500 along the first direction Y and the third direction Z.

[0149] S80: The distance H1 between the first center O1 and the wall of the furnace tube 500 along the first direction Y and the distance H2 along the third direction Z are measured by the distance sensor 29 and fed back to the host computer 200.

[0150] Please see Figure 11 The driving structure 22 drives the ranging sensor 29 to rotate to the pipe wall of the furnace tube 500 along the first direction Y and the third direction Z, respectively, so as to measure the distance H1 between the first center O1 and the pipe wall of the furnace tube 500 along the first direction Y and the distance H2 along the third direction Z, and feed it back to the host computer 200.

[0151] In one embodiment, the ranging sensor 29 measures the distance between the first center O1 and the pipe wall in a single direction along the first direction Y, and also measures the distance between the first center O1 and the pipe wall in a single direction along the third direction Z. The first center O1 and the second center O2 coincide at the pipe opening 501; therefore, the distances of the first center O1 and the second center O2 from the pipe wall along the first direction Y and the third direction Z are equal, and equal to the radius of the second end face A2 of the furnace tube 500.

[0152] like Figure 12 As shown, S90: Drive the propeller 400 to move into the furnace tube 500, and the distance between the first center O1 and the furnace opening along the second direction X is d; use the distance sensor 29 to measure the distance H1a between the first center O1 and the wall of the furnace tube 500 along the first direction Y and the distance H2a along the third direction Z, and feed it back to the host computer 200.

[0153] When the paddle 400 moves into the furnace tube 500, and the distance between the first center O1 and the furnace opening along the second direction X is d, the distance sensor 29 measures the distance H1a between the first center O1 and the wall of the furnace tube 500 along the first direction Y and the distance H2a along the third direction Z, and feeds it back to the host computer 200.

[0154] like Figure 13 and Figure 14 As shown, S100: The first deflection angle δ of the paddle 400 relative to the furnace tube 500 along the first direction Y and the second deflection angle θ of the paddle 400 relative to the furnace tube 500 along the third direction Z are calculated by the host computer 200. The first deflection angle δ satisfies: tanδ=(H1a-H1) / d, and the second deflection angle θ satisfies: tanθ=(H2a-H2) / d.

[0155] S101: Adjust the first deflection angle δ and the second deflection angle θ to 0 respectively.

[0156] By comparing H1a-H1 with 0, the direction of the first deflection angle δ can be determined, that is, whether the propeller 400 deflects in the first direction Y or in the opposite direction of the first direction Y. For example, Figure 12As shown, if H1a is greater than H1, the paddle 400 is offset in the opposite direction of the first direction Y. The paddle 400 needs to move along the first direction Y to adjust its position relative to the furnace tube 500. If H2a is less than H2, the paddle 400 is offset in the third direction Z. The paddle 400 needs to move in the opposite direction of the third direction Z to adjust its position relative to the furnace tube 500.

[0157] The first end 401 of the paddle 400 is generally a cantilever structure, which is prone to falling due to gravity, or the paddle 400 may deflect relative to the furnace tube 500 when it is pushed into the furnace tube 500. Therefore, the paddle 400 needs to be corrected when it enters the furnace tube 500. When the deflection angle of the paddle 400 is small, the paddle 400 can be pushed into the furnace tube 500 in one go, and then the deflection can be corrected. If the deflection angle of the paddle 400 is large, the paddle 400 is pushed multiple times to complete the entry of the paddle 400 into the furnace tube 500. For example, the propeller 400 is driven to move along the second direction X in n times to complete the placement of the propeller 400 inside the furnace tube 500. The distance of each propulsion of the propeller 400 is m, where m*n is greater than the length of the propeller 400 corresponding to the second direction X. Each propulsion of the propeller 400 performs a correction operation: that is, each of the n times performs steps S90, S100 and S101 to further improve the positional accuracy of the propeller 400 relative to the furnace tube 500 along the first direction Y and the third direction Z, which is beneficial to the uniform response of the components inside the propeller 400.

[0158] It is understood that in other embodiments, the ranging sensor 29 can also measure two distances between the first center O1 and the pipe wall in both directions along the first direction Y and the opposite direction of the first direction Y, and the ranging sensor 29 can also measure two distances between the first center O1 and the pipe wall in both directions along the third direction Z and the opposite direction of the third direction Z, thereby obtaining two sets of distances between the first center O1 and the pipe wall in parallel to the first direction Y and the third direction Z, respectively, thereby obtaining two first deflection angles δ and θ, calculating the average value of the first deflection angle δ and the second deflection angle θ, further improving the accuracy of the first deflection angle δ and the second deflection angle θ, which is beneficial to improving the adjustment accuracy of the propeller 400.

[0159] The above-mentioned method for correcting the deflection of the propeller 400 is achieved by communicating with the host computer 200 through the measuring device 100. The measuring device 100 measures the actual coordinates of the propeller 400 along the selected three-coordinate direction and feeds the results back to the host computer 200. The host computer 200 calculates the angle of deflection of the propeller 400 relative to the furnace tube 500. By adjusting these angles to 0 degrees, the deflection correction of the propeller 400 relative to the furnace tube 500 can be completed. No manual measurement is required. One person can complete the deflection correction of the propeller 400 through the host computer 200, which is highly efficient.

[0160] The device 300 for adjusting the paddle deflection uses the measuring device 100 to measure the first center O1 of the first end face A1 of the paddle 400, the second center O2 of the second end face A2 of the furnace tube 500, the distance between the first center O1 and the tube wall at the tube opening 501 of the furnace tube 500, and the distance between the first center O1 and the tube wall when it enters the furnace tube 500 at a distance d. The host computer 200 calculates the deflection angle of the paddle 400 relative to the furnace tube 500: the first deflection angle δ and the second deflection angle θ. The adjustment ends when the value of the deflection angle becomes 0 during the adjustment of the paddle 400, thus completing the correction of the paddle 400 relative to the furnace tube 500.

[0161] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
