Description

Technical Field

[0001] This invention generally relates to the field of crystal rod processing, and specifically to a device and method for detecting the parallelism of wire mesh and oscillating feed plane. Background Technology

[0002] In the field of photovoltaic and semiconductor crystal rod processing, multi-wire cutting machines are the core equipment for crystal rod slicing. Among them, oscillating wire cutting can effectively improve cutting efficiency and make diamond wire wear more uniform through the periodic oscillating motion of diamond wire mesh, thereby improving wire utilization and slicing quality.

[0003] During the oscillating cutting process, the parallelism between the diamond wire mesh and the crystal rod infeed plane is a key parameter to ensure cutting stability, cutting accuracy and product yield. If the parallelism deviation between the two is too large, it will lead to uneven cutting force on the wire mesh and offset of the crystal rod cutting position, which will directly affect the cutting stability and final processing accuracy. Therefore, it is necessary to accurately detect and calibrate this parallelism.

[0004] Currently, most inspection devices used in the industry for multi-wire EDM machines are based on the cutting roller and can only detect the perpendicularity between the wire inlet and outlet ends of the cutting roller. The detection position is fixed, and the detection dimension is singular, failing to cover the overall state of the wire mesh and its relative relationship to the oscillating feed plane. This makes it difficult to adapt to the working conditions of oscillating wire EDM. Such traditional inspection methods cannot achieve accurate measurement of the overall parallelism between the wire mesh and the oscillating feed plane, resulting in low accuracy. They cannot provide a reliable basis for aligning and adjusting the crystal ingot relative to the wire mesh, making it difficult to meet the process requirements of high-precision crystal ingot slicing. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a parallelism detection device for wire mesh and oscillating feed plane, comprising: a straight ruler, wherein the straight ruler is a marble straight ruler, used to be placed above the flange end face of the fixed end spindle of a multi-wire cutting machine as a detection reference; a dial indicator base, disposed on the upper surface of the straight ruler and slidably connected to the straight ruler; a dial indicator, fixed to the dial indicator base, wherein the dial indicator head is vertically upward, used to contact the bottom surface of the crystal rod or the lower edge of the feed mechanism and read displacement data; the dial indicator base can move along the length direction of the spindle or in a direction perpendicular to the spindle to realize full-stroke parallelism detection.

[0006] With the aforementioned technical features, a marble straightedge is placed directly on the end face of the fixed-end spindle flange to establish a detection benchmark. The marble material is not prone to deformation, which reduces the interference of the benchmark's own error on the detection values. The dial indicator base and the straightedge slide together, allowing bidirectional movement along the spindle length and perpendicular to the spindle. Combined with a dial indicator with a vertically upward-arranged head, it can collect displacement data of the bottom surface of the crystal rod and the lower edge of the feed mechanism at multiple points throughout the entire stroke. Compared with the traditional structure that only detects the verticality of the roller at a fixed point, this device can rely on multi-point data comparison to determine the parallelism between the wire mesh and the oscillating feed plane, resulting in a wider detection coverage. The obtained detection data can provide effective reference for the alignment and adjustment of the feed mechanism and crystal rod, adapting to the working conditions of oscillating wire cutting and alleviating the problem of insufficient reference value of single-point detection data.

[0007] In some embodiments, the dial indicator base includes a base body placed on the upper surface of the straightedge and slidably connected to the straightedge; an adjustment rod vertically inserted into the base body; and a connecting rod, one end of which is sleeved with the adjustment rod and slidably connected to the adjustment rod, and the other end of which is fixedly connected to the dial indicator.

[0008] Therefore, the sliding fit between the base and the straightedge allows for coarse adjustment of the overall horizontal and vertical position. The adjustment rod, vertically inserted into the base, enables height adjustment along the vertical direction. The sliding fit between the connecting rod and the adjustment rod allows the dial indicator to perform secondary fine adjustments. The multi-segment sliding adjustment structure allows for flexible adjustment of the vertical height of the dial indicator head, adapting to detection scenarios involving crystal rods of different thicknesses and the lower edge of the feed mechanism at different heights. The segmented adjustment structure completes the position adjustment step by step, making the adjustment process convenient and ensuring that the dial indicator head stably fits the plane to be measured, guaranteeing stable displacement data acquisition. At the same time, the layered sliding structure has a wider adjustment range, improving the device's adaptability to different types of cutting equipment.

[0009] In some embodiments, three straightedges are provided, one of which is placed above the end faces of the two fixed-end spindle flanges, another of which is placed above the end faces of the two movable-end spindle flanges, and the last of which is placed on the upper surface of the two straightedges and is positioned along the axial direction of the main roller. The gauge base is positioned above the straightedge positioned along the axial direction of the main roller and slides along the length of the straightedge. Therefore, two sets of straightedges, one on the fixed end of the main spindle flange and the other on the movable end of the main spindle flange, form the lower support reference. A third straightedge, arranged along the axial direction of the main roller, is then erected above these two. The three straightedges work together to build a complete detection reference that fits the entire axial range of the main roller. The reference fits the flanges at both ends of the main spindle and is consistent with the installation reference of the wire mesh, which can reduce detection deviations caused by reference misalignment. The gauge base is mounted on the axially arranged straightedge and can slide along its length. It can collect multi-point displacement data along the complete axial stroke of the main roller, completely covering the entire working area of ​​the wire mesh. Compared with the method of local detection by a single straightedge, the detection coverage is larger, and the collected multi-point data can more comprehensively reflect the parallel state of the wire mesh and the oscillating feed plane, providing more complete data support for equipment calibration.

[0010] A method for detecting the parallelism of wire mesh and oscillating feed plane, the specific detection method including: For benchmark setup, place the straightedge above the end face of the multi-wire cutting machine shaft flange according to the preset method, and use the straightedge to construct the inspection benchmark plane; Meter installation: Place the base with the dial indicator on the straightedge, so that the dial indicator head is set vertically upward; Align the height and adjust the feed mechanism to move vertically so that the bottom surface of the crystal rod or the lower edge of the feed mechanism contacts the dial indicator head and the dial indicator pointer is within the measurable range. Move the measuring instrument along the preset direction and record the maximum and minimum readings of the dial indicator throughout its entire stroke. The data is calculated by measuring the difference between the maximum and minimum readings to obtain the parallelism between the wire mesh and the oscillating feed plane.

[0011] Therefore, the entire testing method relies on a layered arrangement of straightedges to construct a unified testing benchmark. This benchmark is consistent with the equipment spindle installation benchmark, which can reduce measurement deviations caused by benchmark offset. The instrument assembly and height alignment are completed step by step, and the feed mechanism is adjusted to ensure stable contact between the surface to be measured and the dial indicator head. This ensures that the force state of the dial indicator head is consistent during each measurement, reducing data fluctuations caused by human operation. The dial indicator base is moved along the preset direction to complete the acquisition of multi-point readings throughout the entire stroke. The maximum and minimum readings within the entire stroke range are recorded simultaneously. The difference between the two readings is used to intuitively reflect the overall parallelism deviation. The operation steps are clear and coherent, and the parallelism results can be obtained without complex conversions. The testing process is simple and easy to learn. The acquired full-stroke data can completely reflect the overall parallelism of the wire mesh and the oscillating feed plane, providing a complete and reliable data basis for subsequent equipment calibration.

[0012] In some embodiments, the reference layout is a first layout method: a straightedge is placed simultaneously above the front flange faces of the two fixed-end spindles of the multi-wire cutting machine, and the straightedge is used to construct the detection reference plane. Thus, the detection reference is built using only the straightedge supported by the flange faces of the two fixed-end spindles, simplifying the layout process. No additional straightedge support is needed on the movable-end spindle, reducing the steps for placing the detection fixture and shortening the reference setup time. The reference is formed based on the flange faces of the fixed-end spindles, maintaining consistency with the reference at the wire mesh drive end. This meets the needs of short-stroke, localized rapid detection, and is suitable for quickly verifying the parallelism of the wire mesh near the fixed end. The operation is low-barrier, requiring only one person to complete the fixture setup, making it suitable for daily rapid sampling inspections.

[0013] In some embodiments, the reference layout is a second layout method: three straightedges are provided, one straightedge is provided above the end faces of the two fixed end main shaft flanges, another straightedge is provided above the end faces of the two movable end main shaft flanges, and the last straightedge is provided above the above two straightedges and arranged along the axial direction of the main roller; in the moving measurement, the dial indicator is provided on the top of the straightedge arranged along the axial direction of the main roller and is displaced along the length direction of the straightedge. Therefore, this three-layer flat ruler arrangement, with the fixed-end spindle and the movable-end spindle flange forming the bottom support reference, and the flat rulers arranged along the main roller axis on the upper layer, can build a reference plane covering the entire axial length of the main roller. The reference matches the overall assembly reference of the wire mesh, which can reduce the measurement deviation caused by local limitations of the reference. The gauge base can slide along the entire length of the axial flat ruler, which can complete the point measurement of the entire axial range of the wire mesh and completely collect the displacement data corresponding to each area of ​​the wire mesh. Compared with the local detection scheme that only relies on the fixed-end spindle for local detection, the detection coverage is wider, and the collected data can completely reflect the parallel deviation between the entire wire mesh and the oscillating feed plane, providing more comprehensive data support for the overall calibration of the equipment. It is suitable for working conditions that require a complete evaluation of parallelism, such as factory verification and comprehensive testing of the whole machine.

[0014] In some embodiments, the mechanism above the crystal ingot is adjusted based on the measured parallelism difference. Large adjustments correct the perpendicularity of the feed mechanism to the wire mesh plane, while small adjustments adjust the adhesive plate or loading fixture. Thus, the adjustment range is differentiated based on the dial indicator reading difference, and different adjustment components are matched accordingly. When the parallelism deviation is large, the perpendicularity of the feed mechanism is corrected to reduce the overall parallelism deviation between the wire mesh and the oscillating feed plane. When the parallelism deviation is small, only minor adjustments to the adhesive plate or loading fixture are needed for compensation. This tiered adjustment method, differentiating between large and small ranges, eliminates the need for repeated modifications to large components. Targeted adjustments to corresponding components reduce additional assembly errors caused by over-adjustment. The operation is clearly layered, enabling efficient parallelism calibration while balancing overall deviation correction and fine-precision compensation, adapting to equipment calibration scenarios with varying degrees of deviation.

[0015] In some embodiments, the wire mesh plane is determined by the highest point of the upper end of the diameter of the two cutting rollers, i.e., the main rollers, and the plane formed by placing a straightedge above the outer circumference of the front flange of the fixed end main shaft is used as the reference plane.

[0016] Therefore, the plane where the wire mesh is located is defined by the highest point of the upper end of the two main rollers, which corresponds to the actual layout position of the wire mesh in the actual cutting operation of the equipment. The reference object corresponds to the actual working conditions. A straightedge is set up on the outer circumference of the flange at the front end of the fixed spindle to form a reference plane. This reference is from the same source as the installation reference of the main rollers and the wire mesh, which can reduce the measurement error caused by the mismatch between different references. The measured data can truly reflect the actual parallel deviation between the wire mesh plane and the oscillating feed plane. The test results correspond to the on-site cutting conditions and provide data reference that corresponds to the actual processing state for subsequent mechanism calibration.

[0017] In some embodiments, moving the gauge base along the main axis is for detection along the wire mesh arrangement direction, used to detect the parallelism of the crystal ingot plane or the lower edge of the tool feed mechanism relative to the diamond wire mesh plane along this direction; moving the gauge base along a direction perpendicular to the length of the main axis is for detection along the wire movement direction, used to detect the parallelism of the crystal ingot plane or the lower edge of the tool feed mechanism relative to the diamond wire mesh plane along this direction. Thus, moving the gauge base along the main axis can collect data at multiple points along the wire mesh arrangement direction to determine the parallelism of the crystal ingot plane and the lower edge of the tool feed mechanism relative to the diamond wire mesh plane in this direction. Moving the gauge base along a direction perpendicular to the main axis can complete the detection along the wire movement direction, obtaining parallelism deviation data in another dimension. The two mutually perpendicular detection directions can collect deviation information from different dimensions, fully covering the two key directions of wire mesh operation. Unlike single-direction detection, which can only obtain local deviations, this method comprehensively reflects the overall parallelism between the plane under test and the wire mesh plane, facilitating adjustments by personnel to address deviations in both directions and improving the targeted nature of calibration work.

[0021] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] The following is for reference. Figures 1-8 This invention describes a wire mesh and a method for detecting the parallelism of a sway feed plane.

[0023] Figure 1 This figure shows a front view of a wire mesh and a sway feed plane parallelism detection device according to an embodiment of the present invention. Figure 2A side view of a wire mesh and oscillating feed plane parallelism detection device according to an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 2 As shown, the parallelism detection device for wire mesh and oscillating feed plane provided in this embodiment includes a straight ruler 1, a dial indicator 2, and a dial indicator 3. The straight ruler 1 is made of marble and can be placed above the flange end face of the fixed end spindle of the multi-wire cutting machine to serve as a detection reference. The dial indicator 2 is arranged on the upper surface of the straight ruler 1 and forms a sliding connection with the straight ruler 1. The dial indicator 3 is fixedly assembled on the dial indicator 2, with the dial indicator head facing upward and arranged vertically, so as to contact the bottom surface of the crystal rod 5 or the lower edge of the feed mechanism 43 to read the corresponding displacement data. The dial indicator 2 can move along the length direction of the spindle and in the direction perpendicular to the spindle to complete the parallelism detection work of the entire stroke.

[0024] Figure 3 A partial structural schematic diagram of the wire cutting device in a wire mesh and oscillating feed plane parallelism detection device according to an embodiment of the present invention is shown. (Reference) Figure 1 and Figure 3 As shown, the wire cutting device includes a body 4, inside which two main rollers 41 are arranged in parallel. Each main roller 41 has a fixed end spindle at its front end and a movable end spindle at its rear end. A motor 42 for driving the main rollers 41 to rotate is located on one side of the fixed end spindle in the body 4. Multiple sets of diamond wire mesh are simultaneously sleeved on the periphery of the two main rollers 41. The regular rotation of the diamond wire mesh enables the cutting of the crystal rod 5. A longitudinally movable feed mechanism 43 is provided above the wire mesh, and a feeding fixture 44 is provided below the feed mechanism 43 to fix and install the crystal rod 5.

[0025] The aforementioned straightedge 1 is the reference component for constructing the testing benchmark. The marble material itself is not easily deformed, and the whole is directly supported on the end face of the fixed spindle flange, maintaining consistency with the original assembly benchmark of the equipment spindle. The base 2 is the sliding bearing component that supports the dial indicator 3. Its bottom is attached to the upper surface of the straightedge 1, and a sliding fit structure is set between the two, allowing it to move freely in two orthogonal directions on the surface of the straightedge 1. The dial indicator 3 is the measuring element for collecting height displacement data. The whole is locked and fixed on the base 2, and the indicator head maintains a fixed vertical upward posture, moving synchronously with the base 2. The top of the indicator head can directly abut against the bottom surface of the crystal rod 5 and the lower edge of the feed mechanism 43, completing the acquisition of point height data.

[0026] The marble straightedge 1 establishes a detection benchmark based on the fixed end spindle flange, which can reduce measurement interference caused by the deformation of the benchmark itself; the dial indicator 2 has bidirectional sliding capability, and when paired with the dial indicator 3 with the vertically arranged dial head, it can complete the full stroke multi-point data acquisition in two orthogonal directions, covering the complete detection area corresponding to the wire mesh; compared with the traditional structure that can only detect the verticality of the roller at fixed points, this device can acquire the height data of multiple points on the plane to be measured, thereby determining the parallelism between the wire mesh and the oscillating feed plane, with more detection dimensions. The collected data can provide a reference for the alignment and adjustment of the feed mechanism 43 and the crystal rod 5 tooling, and is suitable for the on-site detection conditions of oscillating wire cutting.

[0027] Figure 4 A perspective view of a wire mesh and oscillating feed plane parallelism detection device according to an embodiment of the present invention is shown. (See reference) Figure 4 As shown, in some embodiments, the base 2 includes a base body 21, an adjusting rod 22 and a connecting rod 23. The base body 21 is placed on the upper surface of the straightedge 1 and is slidably connected to the straightedge 1. The adjusting rod 22 is vertically inserted into the inside of the base body 21. One end of the connecting rod 23 is sleeved on the outside of the adjusting rod 22 and forms a sliding fit with the adjusting rod 22. The other end of the connecting rod 23 is fixedly connected to the dial indicator 3.

[0028] The base 21 is the basic support base of the gauge base 2. It is placed on the surface of the straightedge 1 and can slide relative to the straightedge 1 to achieve overall switching of the detection position. The adjustment rod 22 is a vertical adjustment guide component. It is vertically fixed by plugging and matching with the base 21, and provides a guide base for the sliding adjustment of the connecting rod 23. The connecting rod 23 is a transition connection component. It can slide vertically along the rod of the adjustment rod 22 and at the same time undertake the fixed installation of the dial indicator 3, so that the dial indicator 3 can complete the vertical position adjustment synchronously with the connecting rod 23. The components cooperate step by step to form the adjustment structure of the gauge base 2 that can be vertically fine-tuned.

[0029] This structure, through the multi-stage cooperation of the base 21, the adjusting rod 22, and the connecting rod 23, retains the overall sliding detection function of the base 2 while realizing the flexible adaptive adjustment of the vertical height of the dial indicator 3. It can adapt and adjust the detection position according to different test heights of the bottom surface of the crystal rod 5 or the lower edge of the feed mechanism 43, effectively solving the problems of fixed installation position and poor adaptability of the dial indicator 3 in traditional detection structures. It ensures that the dial indicator 3 head can accurately and stably fit the test surface, avoiding detection gaps and measurement deviations caused by improper height adaptation.

[0030] Figure 5 A front view of another detection method of a wire mesh and oscillating feed plane parallelism detection device according to an embodiment of the present invention is shown; Figure 6 A perspective view is shown illustrating another detection method of a wire mesh and oscillating feed plane parallelism detection device according to an embodiment of the present invention. (See reference) Figure 5 ,6 As shown, in some embodiments, the device is equipped with three straight rulers 1. The first straight ruler 1 is placed above the end faces of the two fixed-end main shaft flanges, the second straight ruler 1 is placed above the end faces of the two movable-end main shaft flanges, and the third straight ruler 1 is laid on the upper surface of the first two straight rulers 1 and arranged along the axial direction of the main roller 41. The dial indicator 2 is placed above the straight rulers 1 arranged along the axial direction of the main roller 41 and can slide along the length direction of the straight ruler 1. The straightedge 1 is a reference component for establishing the testing benchmark. Three straightedges 1 are used in layers. The bottom two straightedges 1 are supported by the fixed end main shaft flange and the movable end main shaft flange, respectively, forming two independent support points. The upper straightedge 1 spans the two bottom straightedges 1 and extends along the axial direction of the main roller 41, establishing a reference carrier that runs through the entire axial range of the main roller 41. The dial indicator base 2 is a sliding base that supports the dial indicator 3. Its bottom and the upper axial straightedge 1 form a sliding fit structure, which can slide along the entire length of the upper straightedge 1. With the sliding action, the dial indicator 3 can synchronously complete the data acquisition of each point in the axial direction.

[0031] The two bottom straightedges 1 are supported by the main shaft flanges at both ends of the equipment. The reference is consistent with the assembly reference of the main shaft and main roller 41, which can reduce the measurement deviation caused by reference misalignment. The upper axially arranged straightedge 1 can form a measurement track covering the entire axial length of the main roller 41. The gauge base 2 can slide along its entire length to collect multi-point displacement data of the entire axial range of the wire mesh. Compared with the form of local detection by only a single straightedge 1, the detection coverage is larger. The measured data can fully reflect the parallel deviation of the wire mesh as a whole and the oscillating feed plane, providing more complete data support for the comprehensive verification of the parallelism of the whole machine.

[0032] Figure 7 A flowchart illustrating one embodiment of the parallelism detection method for wire mesh and oscillating feed plane according to the present invention is shown. (See reference) Figure 7 As shown, a method for detecting the parallelism of wire mesh and oscillating feed plane is described, and the specific detection method includes: The benchmark setup S1 is completed using the first setup method. Before testing, the reference plane corresponding to the wire mesh is determined. The plane where the wire mesh is located is defined by connecting the highest point of the top of the two main rollers 41 of the equipment. This plane is consistent with the position of the diamond wire mesh during the actual cutting operation. The cutting fluid, metal shavings and other debris on the front flange face of the two fixed ends of the main spindle of the multi-wire cutting machine are cleaned. The single marble straightedge 1 is placed stably above the front flange face of the two fixed ends of the main spindle. The placement posture of the straightedge 1 is adjusted to ensure that the bottom surface of the straightedge 1 is fully in contact with the flange face. A complete and continuous test benchmark plane is constructed based on the upper surface of the straightedge 1. Install the instrument S2. Lock the dial indicator 3 onto the base 2 in advance to ensure that the dial indicator 3 is assembled without looseness. Place the assembled base 2 stably on the upper surface of the straightedge 1 that has been placed in place. Adjust the initial position of the base 2 so that the dial indicator 3 head is facing vertically upward. Confirm that the sliding between the base 2 and the straightedge 1 is smooth and without jamming. With height alignment S3, the control device feed mechanism slowly descends vertically, driving the bottom surface of the crystal rod 5 or the lower edge of the tool feed mechanism 43 to gradually approach the head of the dial indicator 3 until the plane to be measured is stably in contact with the top of the head. Continuously adjust the height of the feed mechanism slightly, observe the position of the pointer of the dial indicator 3, and adjust the pointer to the measurable range in the middle of the dial to avoid the pointer being stuck or suspended without reading. Move the measuring instrument S4, pre-set the sliding detection direction, and push the base 2 at a constant speed along the main shaft length direction or perpendicular to the main shaft length direction so that the base 2 slides along the full length of the straightedge 1. Observe the reading of the dial indicator 3 in real time during the sliding process and record the maximum and minimum readings that occur during the entire sliding process. Data calculation S5 extracts the maximum and minimum readings of dial gauge 3 from the records, calculates the difference between the two sets of readings, and this difference can reflect the parallel deviation between the wire mesh and the oscillating feed plane, thereby obtaining the parallelism data between the wire mesh and the oscillating feed plane.

[0033] Operation correction S6 determines the magnitude of the deviation based on the calculated parallelism difference and performs targeted correction operations on the supporting mechanism above the crystal rod 5. When the parallelism difference is large and is determined to be a significant deviation, the installation position and support angle of the feed mechanism 43 are corrected as a whole, and the perpendicularity of the feed mechanism 43 relative to the wire mesh plane is adjusted to reduce the parallelism deviation between the two planes from an overall perspective. When the parallelism difference is small and is determined to be a minor deviation, only the installation position and flatness of the adhesive plate or the placement height and levelness of the loading fixture 44 are finely adjusted, and the minor parallelism deviation is compensated by local components.

[0034] Figure 8 Another flowchart of a method for detecting the parallelism of a wire mesh and a swaying feed plane according to an embodiment of the present invention is shown. (See reference) Figure 8 As shown, a method for detecting the parallelism of wire mesh and oscillating feed plane is described, and the specific detection method includes: For the baseline setup, the second setup method is used to complete the baseline construction. Before testing, the reference plane corresponding to the wire mesh is determined. The plane where the wire mesh is located is defined by the line connecting the highest point of the top of the two main rollers 41 of the equipment. This plane is consistent with the position of the diamond wire mesh during the actual cutting operation. Clean the debris and cutting fluid from the surface of the fixed end spindle flange and the moving end spindle flange of the multi-wire cutting machine. Take two straight rulers 1 and place them stably above the two sets of spindle flanges, ensuring that the bottom surface of the straight ruler 1 is completely in contact with the flange end face. Then take a third straight ruler 1 and place it across the upper surface of the first two straight rulers 1. Adjust the placement of the third straight ruler 1 so that it extends along the axial direction of the main roller 41. The three layers of straight rulers 1 are used to form a complete and continuous test reference plane.

[0035] For instrument installation, lock and fix the dial indicator 3 onto the base 2 in advance to ensure that the dial indicator 3 is assembled without looseness. Place the assembled base 2 stably on the upper surface of the straightedge 1 that has been placed in place. Adjust the initial position of the base 2 so that the dial indicator 3 head is facing vertically upward. Confirm that the sliding between the base 2 and the straightedge 1 is smooth and without jamming. With the height aligned, the feeding mechanism of the control equipment slowly descends in the vertical direction, driving the bottom surface of the crystal rod 5 or the lower edge of the cutting mechanism 43 to gradually approach the head of the dial indicator 3 until the plane to be measured is stably in contact with the top of the head. Continuously adjust the height of the feeding mechanism slightly, observe the position of the pointer of the dial indicator 3, and adjust the pointer to the measurable range in the middle of the dial to avoid the pointer being stuck or suspended without reading. The moving measurement method is pre-set with a sliding detection direction. During the detection, point measurements can be carried out in two orthogonal directions. The dial indicator 3 is mounted on the top of the third straightedge 1 arranged along the axial direction of the main roller 41. The initial position of the dial indicator 2 is adjusted to ensure that the sliding is smooth. The dial indicator 2 is operated to move at a constant speed along the entire length of the straightedge 1 along the axial direction. During the sliding process, the dial indicator 3 continuously contacts the surface to be measured to complete the data acquisition of each point. The movement trajectory corresponds to the overall layout and extension direction of the wire mesh. During the movement, the dial indicator 3 continuously presses against the plane of the crystal rod 5 or the lower edge of the feed mechanism 43, collecting height values ​​at multiple points along the axial direction to determine the parallelism of the crystal rod 5 plane and the lower edge of the feed mechanism 43 relative to the diamond wire mesh plane in the wire mesh layout direction. After completing the axial detection, the sliding position of the dial indicator base 2 is adjusted, and the base 2 is moved smoothly along a horizontal direction perpendicular to the length of the main shaft. This movement path matches the movement direction of the reciprocating diamond wire. Throughout the process, the dial indicator head maintains stable contact with the surface to be measured and records the readings at each point to detect the parallelism of the crystal rod 5 plane and the lower edge of the feed mechanism 43 relative to the diamond wire mesh plane in the wire movement direction. The dial indicator base 2 is pushed at a constant speed along the length of the main shaft or perpendicular to the length of the main shaft, allowing the base 2 to slide along the entire length of the straightedge 1. During the sliding process, the reading of the dial indicator 3 is observed in real time, and the maximum and minimum readings occurring throughout the entire sliding process are recorded.

[0036] Data calculation involves extracting the maximum and minimum readings of dial indicator 3 from the records, and calculating the difference between the two sets of readings. This difference reflects the parallelism deviation between the wire mesh and the oscillating feed plane, thereby obtaining the parallelism data between the wire mesh and the oscillating feed plane.

[0037] The operation is corrected by determining the magnitude of the deviation based on the calculated parallelism difference value and implementing targeted correction operations on the supporting mechanism above the crystal rod 5. When the parallelism difference value is large and is determined to be a significant deviation, the installation position and support angle of the feed mechanism 43 are corrected as a whole, and the perpendicularity of the feed mechanism 43 relative to the wire mesh plane is adjusted to reduce the parallelism deviation between the two planes from an overall perspective. When the parallelism difference value is small and is determined to be a minor deviation, only the installation position and flatness of the adhesive plate or the placement height and levelness of the loading fixture 44 are finely adjusted to compensate for the minor parallelism deviation by relying on local components.
