Technical Field
[0001] This application relates to the field of diamond wire manufacturing technology, and in particular to a diamond wire processing method and apparatus. Background Technology
[0002] Diamond wire saws, also known as diamond wire saws, are key tools for cutting hard and brittle materials such as crystalline silicon, sapphire, and precision ceramics. The core of their manufacturing lies in using a composite electroplating process to firmly bond diamond micropowder to a metal matrix; furthermore, the diamond wire needs to be sharpened, that is, removing the excess plating layer covering the diamond particles to expose the sharp edges of the abrasive grains and restore their cutting ability.
[0003] In existing technologies, diamond wire is usually sharpened by mechanical grinding, such as using a whetstone to rub the diamond wire at high speed. However, the cross-section of diamond wire is circular, and mechanical grinding cannot cover the entire circumference of the diamond wire, resulting in natural grinding blind spots. It is difficult to achieve uniform sharpening of the diamond wire cross-section at 360°, which leads to large differences in the exposed edge height of diamond abrasive grains at different locations and poor edge consistency, resulting in poor sharpening effect of diamond wire.
[0004] Therefore, the technical problem with the existing technology is that the diamond wire does not achieve good sharpening effect. Summary of the Invention

[0024] Diamond wire 600 is a core consumable for cutting photovoltaic silicon wafers, sapphire, and semiconductor wafers. Sharpening is a crucial process in its production, involving grinding away the electroplated nickel layer on the surface of the diamond abrasive grains with a grinding wheel to expose the diamond tips and achieve stable cutting capability. Existing sharpening technology has several problems: First, a single-set opposing grinding structure can only grind the radial sides of the diamond wire 600, creating a natural grinding blind zone and failing to achieve 360° uniform sharpening. The exposed height of the diamond abrasive grains varies significantly at different locations, resulting in poor sharpening consistency. Second, the prolonged friction between the diamond wire 600 and the grinding wheel in a fixed position creates deep indentations on the grinding wheel's working surface, causing fluctuations in sharpening pressure. Simultaneously, the large amount of heat generated by this fixed-point friction accelerates the aging of the grinding wheel substrate and the carbonization of the diamond abrasive grains, compromising the quality of sharpening.
[0025] The purpose of this application is to overcome the above-mentioned defects of the prior art and provide a diamond wire 600 processing method and device. It achieves 360° full-circumference sharpening through orthogonal double-group grinding, solves the problem of overheating and wear of grinding wheels through temperature-driven three-zone cyclic rotation, solves the problem of tension fluctuation in cross-zone adjustment through tension control logic of pre-compensation and then adjustment, and solves the problem of dent overlap through dynamic offset of full-zone cyclic return zone. At the same time, it achieves the core objectives of high sharpening consistency, long grinding wheel life, and stable mass production operation.
[0026] This application provides a method for machining diamond wire 600, applicable to diamond wire 600 machining equipment, such as... Figure 1As shown, the diamond wire 600 processing device includes a first grinding assembly 100, a first adjusting member 200, a second grinding assembly 300, a second adjusting member 400, and an adjusting wheel 500. The first grinding assembly 100 includes two first grinding wheels 110 arranged side by side, which are used to allow the diamond wire 600 to pass between the two first grinding wheels 110 and to grind and sharpen the diamond wire 600. The first grinding wheels 110 are arranged vertically. The first adjusting member 200 is disposed on the side of the first grinding wheel 110 and is used to adjust the diamond wire 600 on the first grinding wheel. Position on 110; the second grinding assembly 300 includes two second grinding wheels 310 arranged side by side, for passing the diamond wire 600 between the two grinding wheels 310 and grinding and sharpening the diamond wire 600; the second grinding wheels 310 are arranged horizontally; a second adjusting member 400 is disposed on the side of the second grinding wheel 310, and the second adjusting member 400 is used to adjust the position of the diamond wire 600 on the second grinding wheel 310; and an adjusting wheel 500 has a degree of freedom of movement, through which the diamond wire 600 is driven to adjust the tension of the diamond wire 600; like Figure 2 As shown, the processing method for diamond wire 600 includes: S1: The diamond wire 600 is driven through the adjusting wheel 500, the first grinding wheel 110 and the second grinding wheel 310, so that the first grinding wheel 110 and the second grinding wheel 310 grind and sharpen the diamond wire 600. S2: Predetermine the first displacement of the first adjustment component 200 driving the diamond wire 600 on the first grinding wheel 110, and the second displacement of the second adjustment component 400 driving the diamond wire 600 on the second grinding wheel 310. S3: Based on the first displacement and the second displacement, determine the compensation movement of the adjusting wheel 500; S4: The adjustment wheel 500 is moved based on the compensation movement to pre-compensate the tension of the diamond wire 600.
[0027] The first grinding assembly 100 includes two parallel grinding wheels 110, which are installed opposite each other, forming a first grinding gap in the middle for the diamond wire 600 to pass through. When the diamond wire 600 passes through the gap, the two grinding wheels 110 form a symmetrical clamping and grinding on the upper and lower sides of the diamond wire 600. The first grinding wheels 110 are arranged vertically, and the working surface extends vertically. The first adjusting member 200 is disposed on the wire inlet side of the first grinding wheel 110 and is used to drive the diamond wire 600 to move up and down in the vertical direction and adjust the axial contact position of the diamond wire 600 on the first grinding wheel 110.
[0028] The second grinding assembly 300 includes two parallel grinding wheels 310, which are installed opposite each other, forming a second grinding gap in the middle for the diamond wire 600 to pass through. The grinding wheels 310 are arranged horizontally, with the horizontal direction perpendicular to the vertical direction. The first grinding wheel 110 grinds the upper and lower sides of the diamond wire 600, and the second grinding wheel 310 grinds the left and right sides of the diamond wire 600. The two sets of grinding wheels can cover the entire circumference of the diamond wire 600, achieving uniform sharpening around the circumference and eliminating the blind spot problem of existing grinding. The second adjusting component 400 is disposed on the side of the second grinding wheel 310 and is used to drive the diamond wire 600 to move left and right in the horizontal direction, adjusting the axial contact position of the diamond wire 600 on the second grinding wheel 310.
[0029] The adjusting wheel 500 is located at the inlet end of the grinding assembly and has the freedom to move up and down. The diamond wire 600 is driven around the adjusting wheel 500 to adjust the overall tension of the diamond wire 600. The winding method used in this application is the half-stroke winding method commonly used in conventional mass production equipment. The diamond wire 600 enters horizontally from the left, winds around the lower semi-circular arc of the adjusting wheel 500, and then exits horizontally to the right to the grinding wheel. The inlet and outlet wires are parallel and on the same horizontal plane. The adjusting wheel 500 only moves up and down.
[0030] The first adjusting member 200 and the second adjusting member 400 can be adjusting wheels. The adjusting wheels are set at the front end of the diamond wire 600 inlet of the first grinding component 100 and the second grinding component 300. Preferably, two adjusting wheels are set, and the two adjusting wheels clamp the diamond wire 600 so that the position of the diamond wire 600 relative to the grinding wheel is adjusted.
[0031] The diamond wire 600 processing method includes: First, controlling the diamond wire 600 to sequentially pass through the adjusting wheel 500, the first grinding gap, and the second grinding gap, and using the first grinding wheel 110 and the second grinding wheel 310 to perform full-circumference grinding and sharpening of the orthogonal side of the diamond wire 600; Second, before performing the diamond wire 600 position adjustment, pre-determining the first displacement amount of the first adjusting component 200 driving the diamond wire 600 to move across the zone, and the second displacement amount of the second adjusting component 400 driving the diamond wire 600 to move across the zone; Third, calculating the compensation movement amount of the adjusting wheel 500 based on the first and second displacement amounts; Fourth, first driving the adjusting wheel 500 to move based on the compensation movement amount to complete the tension pre-compensation of the diamond wire 600, and then driving the first adjusting component 200 and the second adjusting component 400 to drive the diamond wire 600 to complete the cross-zone position adjustment. First, the adjusting wheel 500 moves based on the compensation movement to complete the tension pre-compensation of the diamond wire 600, and to release or tighten the diamond wire 600 of the corresponding length in advance. Then, the first adjusting component 200 and the second adjusting component 400 are driven to move the diamond wire 600 to complete the cross-zone position adjustment. This sequence completely solves the lag problem of passive compensation in the prior art, completely eliminates tension fluctuations during the adjustment process, and avoids the diamond wire 600 from breaking, loosening, or deviating.
[0032] Furthermore, the working surface temperature of the grinding wheel is used as the trigger condition for zone switching to achieve intelligent zone switching that is adaptive to working conditions, thus avoiding the experience-based errors of zone switching at fixed times.
[0033] like Figure 3 , 4 As shown, the first grinding wheel 110 and the second grinding wheel 310 have several regions along the axial direction, and a temperature sensor is provided in each region; the first displacement of the diamond wire 600 driven by the first adjusting member 200 on the first grinding wheel 110 and the second displacement of the diamond wire 600 driven by the second adjusting member 400 on the second grinding wheel 310 are predetermined, including: S21: Set the temperature threshold; S22: Obtain the real-time temperature value of the area where the diamond wire 600 is located; S23: Based on the real-time temperature value and temperature threshold, adjust the regional position of the diamond wire 600 on the first grinding wheel 110 and the second grinding wheel 310; S24: Determine the first displacement and the second displacement.
[0034] The first grinding wheel 110 and the second grinding wheel 310 are each divided into several independent working areas along the axial direction. Each working area has an independent temperature sensor at its center, which can independently collect the real-time working surface temperature of the corresponding area. The temperature collection of different areas does not interfere with each other, avoiding temperature crosstalk between adjacent areas. In one embodiment, the temperature sensor can be a contact or non-contact temperature sensor, such as a thermocouple or an infrared temperature sensor.
[0035] Specifically, firstly, a working temperature threshold for the grinding wheel is preset. This threshold is calibrated in advance through aging tests based on the grinding wheel material and the diamond wire 600 specification, and represents the highest safe temperature for the grinding wheel to operate normally. In one embodiment, the temperature threshold is set to 80°C. Exceeding this temperature will cause the aging rate of the grinding wheel substrate to increase exponentially. Then, the real-time temperature value of the working area where the diamond wire 600 is located is obtained in real time through temperature sensors in each area at a certain sampling frequency and transmitted to the equipment PLC control unit. Finally, based on the comparison between the real-time temperature value and the preset temperature threshold, the control unit outputs the corresponding cross-area adjustment command. Based on the distance between the target area and the current area, the first displacement and the second displacement are calculated.
[0036] It is worth noting that temperature is a direct indicator of the wear degree and dent depth of the grinding wheel. The more severe the wear of the grinding wheel and the deeper the dent, the larger the friction contact area, the more heat is generated and the higher the temperature. Compared with the fixed-time area changing scheme, temperature triggering can adapt to dynamic working conditions with different wire diameters, different wire feed speeds and different coating thicknesses. It avoids the problem of wasting the working surface of the grinding wheel by changing the area in advance and aggravating the wear of the grinding wheel by changing the area in a delayed manner, thereby maximizing the utilization rate of the working surface of the grinding wheel.
[0037] Among them, such as Figure 5 As shown, based on the first displacement and the second displacement, the compensation movement of the adjusting wheel 500 is determined as follows: S31: Obtain the first displacement, the second displacement, and the distance between the first grinding wheel 110 and the second grinding wheel 310; S32: Determine the first length of the diamond wire 600 between the first grinding wheel 110 and the second grinding wheel 310 after the diamond wire 600 is adjusted; S33: Determine the length difference of the diamond wire 600 based on the first length and the second length; wherein, the second length is the length of the diamond wire 600 between the first grinding wheel 110 and the second grinding wheel 310 before the diamond wire 600 is adjusted; S34: Determine the compensation movement of the adjusting wheel 500 based on the length difference of the diamond wire 600.
[0038] In other words, such as Figure 6As shown, the calculation logic of the compensation movement of the adjusting wheel 500 achieves precise active pre-compensation of tension through precise quantitative calculation of the difference in wire length. The calculation of the compensation movement follows geometric logic. Specifically, firstly, the first displacement, the second displacement, and the fixed center distance between the first grinding wheel 110 and the second grinding wheel 310 are obtained. This center distance is a fixed value calibrated during equipment installation and commissioning and remains unchanged throughout the equipment operation. Then, based on spatial geometric relationships, the first length of the diamond wire 600 wire between the contact point of the diamond wire 600 on the first grinding wheel 110 and the contact point of the diamond wire 600 on the second grinding wheel 310 is calculated after the cross-zone adjustment. Next, the second length of the diamond wire 600 wire between the two contact points is calculated before the cross-zone adjustment. The difference between the first length and the second length is calculated to obtain the wire length increment for this adjustment. Finally, based on the wire length increment and the winding method of the adjusting wheel 500, the actual compensation movement of the adjusting wheel 500 is determined.
[0039] like Figure 6 As shown, cross-zone adjustment changes the relative spatial position of the contact points of the two grinding wheels, thereby changing the length of the diamond wire 600 between the two points. Every 1mm change in the wire length will cause a fluctuation of more than 10N in the tension of the diamond wire 600, which is far beyond the allowable tension range of the diamond wire 600. Therefore, it is necessary to compensate for this length change in advance by moving the adjusting wheel 500 to ensure that the tension of the diamond wire 600 remains within the set range during the adjustment process. Existing technologies generally use a passive compensation method based on tension sensor feedback, which has a lag and cannot eliminate the tension impact at the moment of adjustment. However, the active pre-compensation of this solution can achieve zero-fluctuation adjustment of tension.
[0040] Furthermore, the compensating movement of the adjusting wheel 500 is:
[0041] Based on the positional changes in this adjustment, the precise calculation of the 500mm movement of the adjusting wheel is used to exactly offset tension fluctuations, achieving zero-impact adjustment; among other things... The compensation movement of the adjusting wheel 500 is the distance that the adjusting wheel 500 needs to move up and down in the vertical direction. A positive value indicates downward movement to release tension, and a negative value indicates upward movement to tighten tension. The fixed distance between the first grinding wheel 110 and the second grinding wheel 310 is a fixed center distance between the first grinding wheel 110 and the second grinding wheel 310. This fixed center distance is a fixed value for equipment installation and remains unchanged throughout the entire process. This refers to the vertical distance of the diamond wire 600 on the first grinding wheel 110 relative to its initial position after this adjustment. The vertical distance of the diamond wire 600 on the first grinding wheel 110 relative to its initial position after the previous adjustment; This refers to the horizontal distance of the diamond wire 600 on the second grinding wheel 310 relative to its initial position after this adjustment. The horizontal distance of the diamond wire 600 on the second grinding wheel 310 relative to the initial position after the previous adjustment.
[0042] The first grinding wheel 110 and the second grinding wheel 310 are arranged orthogonally, and the two contact points form a three-dimensional rectangular coordinate system. The spatial straight-line distance between the two contact points is adjusted to... That is, the first length; the spatial straight-line distance between the two contact points after adjustment is The difference between the two is the increase in the cable length for this adjustment. Since the adjusting wheel 500 uses a half-stroke winding method, it is equivalent to a movable pulley structure: for every 1mm that the adjusting wheel 500 moves downward, the infeed length is released by 1mm and the outfeed length is released by 1mm simultaneously, and the total cable length is released by 2mm. Therefore, the actual movement of the adjusting wheel 500 is half of the cable length increment, corresponding to the 1 / 2 coefficient in the formula.
[0043] For example, the grinding wheel is divided into sections. The grinding wheel adopts the industry mainstream 900mm specification and is divided into three equal-length working areas along the axial direction, with a single section length of 300mm. When it is necessary to adjust the diamond wire 600, the first and second displacements of the diamond wire 600 are large strokes of 300mm. The adjusting component alone cannot directly drive the diamond wire 600 to move. Forced adjustment will cause the tension of the diamond wire 600 to rise suddenly and break. Therefore, the adjusting wheel 500 is set to release the tension of the diamond wire 600 in advance, which can significantly reduce the load on the adjusting component and help the adjusting component to smoothly drive the diamond wire 600 to the position on the first grinding wheel 110 and the second grinding wheel 310.
[0044] For example, when adjusting from zone 101 to zone 102, the first displacement is 300mm and the second displacement is 300mm. The fixed center distance between the two grinding wheels is L=570mm. Substituting into the formula, we can calculate that the increase in the routing length is about 140.6mm. The compensation movement of the adjusting wheel 500 is 70mm. That is, by controlling the adjusting wheel 500 to move downward by 7cm, the routing length of 140.6mm is released, which completely offsets the length change caused by crossing zones.
[0045] To improve the sharpening quality of the diamond wire 600 by the grinding wheels, this design divides the grinding wheels into sections, resulting in a longer axial length. When adjusting the diamond wire 600, its first and second displacements involve large strokes. The adjusting mechanism alone cannot directly move the diamond wire 600; forced adjustment would cause a sudden increase in tension, leading to breakage. Therefore, the adjusting wheel 500 is used to pre-release the tension of the diamond wire 600, significantly reducing the load on the adjusting mechanism and facilitating a smoother movement of the diamond wire 600 on the first grinding wheel 110 and the second grinding wheel 310. The large strokes of the cross-section displacement cause significant millimeter-level changes in the wire length between the two grinding wheels. The adjusting wheel 500 must pre-compensate for the tension; otherwise, the diamond wire 600 will break or loosen.
[0046] It should be noted that this application also adjusts the offset of the diamond wire 600 in the grinding wheel area. The offset in the area is a small displacement, which is much smaller than the elastic deformation range of the diamond wire 600 itself. It will not cause perceptible tension fluctuations. Moreover, the offset is completed in the same area and will not cause changes in the length of the wire across areas. Therefore, it is not necessary to include it in the compensation calculation of the adjusting wheel 500, which is completely in line with the actual engineering situation.
[0047] The adjustment of the diamond wire 600's position on the first grinding wheel 110 and the second grinding wheel 310 based on real-time temperature values and temperature thresholds includes: If the real-time temperature value is less than the temperature threshold, maintain the current position; if the real-time temperature value is greater than or equal to the temperature threshold, adjust the diamond wire 600 to the next area; wherein, the initial position of each area is predefined, and each initial position is set at equal intervals along the axis of the grinding wheel. When adjusting the position of diamond wire 600, diamond wire 600 is adjusted from the initial position of the previous region to the initial position of the next region; Each grinding wheel includes a first zone 101, a second zone 102, and a third zone 103; The adjustment path of the diamond wire 600 is as follows: from zone 101 to zone 102, from zone 102 to zone 103, from zone 103 to zone 101, and so on.
[0048] Specifically, the temperature-triggered zone switching is executed as follows: If the real-time temperature value of the current working area is less than the preset temperature threshold, it indicates that the frictional heat generation in the current area is within a safe range, the wear of the grinding wheel is low, and the depth of the dent has not yet affected the sharpening effect. Therefore, the current position of the diamond wire 600 is maintained, and grinding continues in the current area. If the real-time temperature value of the current working area is greater than or equal to the preset temperature threshold, it indicates that obvious wear dents have been generated in the current area. Continuing to grind will lead to a decrease in the sharpening quality. Therefore, the control adjustment component moves the diamond wire 600 to the next adjacent working area.
[0049] During the equipment debugging phase, the reference initial position of each working area is predefined. Each initial position is set at equal intervals along the axis of the grinding wheel. The distance between adjacent initial positions is equal to the axial length of a single working area. This initial position is the unified zero-point reference for grinding operations in each area. All adjustment actions are based on this reference. When adjusting across areas, the diamond wire 600 is directly adjusted from the initial position of the previous area to the initial position of the next area. All area-changing actions are based on the fixed initial position, which can completely eliminate the cumulative position error of area changing. No matter how many cycles or how many area-changing actions are performed, there will be no positional deviation, preventing the diamond wire 600 from falling on the area boundary.
[0050] like Figure 7-9 As shown, each grinding wheel is divided into three equal-length working areas, namely Zone 101, Zone 2, and Zone 3, from the reference end. The fixed adjustment path of the diamond wire 600 is: Zone 101 is adjusted to Zone 2, Zone 2 is adjusted to Zone 3, and Zone 3 is adjusted to Zone 101, and so on. When the three areas are cycled, after a single area is no longer in use, the cooling time is equal to the sum of the working times of the other two areas, which allows it to cool naturally to room temperature, eliminating the risk of overheating. At the same time, the length of the grinding wheel is moderate and suitable for the installation space.
[0051] In the loop after the diamond wire 600 enters the first zone 101, the second zone 102 and the third zone 103 for the second time, an offset adjustment step is also performed: the offset is adjusted based on the initial position of the target area so that the diamond wire 600 is located at the offset position after the offset adjustment.
[0052] In other words, in all cycles after the diamond wire 600 re-enters Zone 101, Zone 102, and Zone 103, an offset adjustment step is performed within the zone. This rule covers all cycles and return scenarios in all zones, not just when returning from Zone 103 to Zone 101. Whenever a certain zone is entered for grinding for the first time, a dent is formed at the initial position of that zone. Upon re-entry into the zone a second time or subsequent times, if it lands directly at the initial position, it will completely embed itself into the previously formed dent, causing a sharpening pressure drop drastically. Therefore, regardless of whether it returns to Zone 101, Zone 102, or Zone 103, unless it's the first time entering, an offset adjustment must be performed.
[0053] like Figure 10As shown, offset adjustment refers to adjusting a preset dynamic offset along the axial direction of the corresponding grinding wheel, using the reference initial position of the currently entered target area as the reference origin. This ensures that the diamond wire 600 is located in a new working position after the offset adjustment, rather than directly falling on the reference initial position. For the vertically set first grinding wheel 110, the offset direction is upward along the vertical axis; for the horizontally set second grinding wheel 310, the offset direction is to the right along the horizontal axis. The offset direction is fixed to ensure that all indentations are arranged sequentially along the axial direction without overlapping.
[0054] Taking a complete large cycle as an example: In the first large cycle (N=1), the diamond wire 600 enters the first zone 101, the second zone 102, and the third zone 103 for the first time, each landing at its respective reference initial position, forming three initial indentations; In the second large cycle (N=2), when the diamond wire 600 enters the first zone 101, it shifts upwards by the corresponding offset amount based on the initial position of the first zone 101; when it enters the second zone 102, it shifts upwards by the corresponding offset amount based on the initial position of the second zone 102; when it enters the third zone 103, it shifts upwards by the corresponding offset amount based on the initial position of the third zone 103. All three zones avoid the old indentations formed in the first cycle; In the third large cycle (N=3), all three zones are offset by the offset amount of the current shift on the basis of the previous shift, avoiding all the old indentations formed in the previous two cycles. And so on, no matter how many cycles there are, there will never be overlapping indentations.
[0055] It should be noted that the offset within the region is a small displacement, much smaller than the elastic deformation range of the diamond wire 600 itself, and will not cause perceptible tension fluctuations. Moreover, the offset is completed within the same region and will not cause changes in the length of the wire across regions. Therefore, it is not included in the calculation of the compensation movement of the adjusting wheel 500, and there is no need to adjust the position of the adjusting wheel 500, which greatly simplifies the control logic.
[0056] The offset is determined by using a dynamic function model instead of a fixed empirical step size, which improves the anti-overlap effect and the utilization rate of the grinding wheel's working surface; for example... Figure 11 As shown, it includes: T1: Establish a functional model of the target area temperature, the pressure of the grinding wheel on the diamond wire 600, the diameter of the diamond wire 600, and the amount of indentation expansion of the diamond wire 600 on the grinding wheel with respect to the offset. T2: Based on the temperature of the target area, the pressure of the grinding wheel on the diamond wire 600, and the function model, confirm the offset.
[0057] The offset is determined using a dynamic quantitative calculation method, rather than a fixed empirical value, including: First, a pre-established offset calculation function model is created. The input parameters of this model include the real-time temperature of the target area, the real-time clamping force of the grinding wheel on the diamond wire 600, the nominal diameter of the diamond wire 600, and the lateral expansion of the diamond wire 600 in the indentation on the grinding wheel. The output parameter is the precise offset for the current cycle. The function model is pre-calibrated through numerous compression and temperature experiments, enabling it to calculate the indentation width under all working conditions. During actual operation, the real-time temperature of the target area and the clamping force of the grinding wheel on the diamond wire 600 are collected and substituted into the pre-established function model to determine the optimal offset for the current cycle.
[0058] Taking the first grinding wheel 110 as an example, during the cyclic switching between zones, the diamond wire 600, by offsetting an additional amount based on its initial height, can completely avoid all previously formed old dents and perform grinding and sharpening on a brand-new, dent-free working surface within the target zone. This solves the problem of overlapping dents during cyclic zone switching and ensures the stability of sharpening pressure and the consistency of sharpening effect. For example, in the second cycle after entering the first zone 101, when the diamond wire 600 needs to be adjusted from the first zone 101 to the second zone 102, the diamond wire 600 first reaches the initial position of the second zone 102, and then, based on the calculated offset, adds the offset distance to the initial position of the second zone 102, so that the diamond wire 600 is in a brand-new, unworn position in the second zone 102. Here, the target zone refers to the area that the diamond wire 600 is about to adjust to. For example, when adjusting from the first zone 101 to the second zone 102, the second zone 102 is the target zone; when adjusting from the third zone 103 to the first zone 101, the first zone 101 is the target zone.
[0059] The offset directly determines the anti-overlap effect and the utilization rate of the grinding wheel's working surface: if the offset is set too large, it will lead to ineffective waste of the grinding wheel's working surface, significantly reducing the effective service life of the grinding wheel; if the offset is set too small, the diamond wire 600 will partially or completely re-enter the existing indentation, failing to achieve the anti-overlap effect. A dynamic calculation model can adapt to all working conditions, minimizing the offset while ensuring complete avoidance of the old indentation, thus maximizing the utilization rate of the grinding wheel's working surface.
[0060] Furthermore, the offset is:
[0061] This is the amount of base extension for the dent on the grinding wheel; It is a diamond wire with a diameter of 600. To apply 600 pressure from the grinding wheel to the diamond wire; The indentation expansion coefficient corresponding to the clamping force; The coefficient for the expansion of the dents on the grinding wheel; This represents the temperature difference between the target area and normal temperature. Specifically, the offset for a single loop is calculated using the following formula:
[0062] Based on the current real-time operating conditions, the minimum offset that can perfectly cover the width of the old dent is calculated, while taking into account both the anti-overlap effect and the utilization rate of the grinding wheel's working surface. Based on the current real-time operating conditions, the minimum offset that can perfectly cover the total width of the old dent is calculated, ensuring 100% no dent overlap while maximizing the utilization rate of the grinding wheel's working surface.
[0063] The offset calculation is based on the physical width of the dent: the basic width of the dent is equal to the nominal diameter of the diamond wire 600 itself. When the soft resin grinding wheel is pressed by the diamond wire 600, the contact position will bulge out symmetrically to the left and right. Therefore, the total expansion of the dent is twice the single-sided expansion. The single-sided expansion is linearly superimposed by the basic expansion, the additional expansion caused by pressure, and the additional expansion caused by temperature. Finally, the above formula is obtained by combining the three parts.
[0064] in, The base expansion amount of the dent on the grinding wheel is a fixed value of lateral expansion caused by the grinding wheel under pressure at room temperature and rated pressure, which is calibrated in advance through compression test; The nominal diameter of the diamond wire 600 is input into the control system in advance according to the specifications of the diamond wire 600 to be processed; The real-time clamping force of the grinding wheel on the diamond wire 600 is collected in real time by the pressure sensor on the grinding wheel mounting base; The indentation expansion coefficient corresponding to the clamping force is an inherent property of the grinding wheel material. It represents the lateral expansion increment of the indentation when the clamping force increases by 1N, and is calibrated in advance through experiments. The dent propagation coefficient corresponding to temperature is the propagation property of the grinding wheel material as temperature changes. It represents the lateral propagation increment of the dent when the temperature increases by 1°C, and is calibrated in advance through experiments. The temperature difference between the target area and the ambient temperature is collected and calculated in real time by a temperature sensor. Thus, based on the three influencing factors of the diamond wire 600 itself, the indentation expansion caused by pressure, and the indentation expansion caused by temperature, the calculated offset can completely cover the actual total width of the indentation, ensuring that there is no overlap.
[0065] Understandably, the offset Essentially, it's about finding the minimum distance that ensures the newly polished area doesn't overlap with the old dent from the previous polishing. To achieve the optimal effect of no overlap and no waste, the width of the indentation must be equal to the total width of the old dent. Since diamond wire 600 is cylindrical, even if the grinding wheel does not deform at all, the base width of the indentation must be at least equal to the nominal diameter of the diamond wire 600. This is the minimum reference for the width of the indentation; furthermore, when the diamond wire 600 contacts the grinding wheel during sharpening, the excellent feedback recalls the symmetrical protrusion deformation on both sides, so the actual width of the indentation will be slightly larger than the diameter of the diamond wire 600, and there is an expansion amount on each side, with the total expansion amount being twice the single-sided expansion amount.
[0066] The one-sided expansion is composed of the superposition of three linear influence terms, including , , In other words, under normal temperature and rated pressure, the inherent lateral expansion of the grinding wheel material itself. This is a material value independent of operating conditions, calibrated in advance through experiments; clamping force The larger the temperature, the deeper the grinding wheel is pressed, and the greater the lateral bulge. Within the elastic working range, the material of the grinding wheel exhibits a linear relationship between compression deformation and pressure. Furthermore, the higher the temperature, the softer the polymer grinding wheel and the lower its elastic modulus, resulting in greater compression deformation under the same pressure and a corresponding increase in lateral expansion. Therefore, the total width of the combined indentation (i.e., the minimum offset) is calculated as the diameter of the diamond wire 600 + 2 × (basic expansion + pressure expansion + temperature expansion).
[0067] This formula applies to both the vertically positioned first grinding wheel 110 and the horizontally positioned second grinding wheel 310, differing only in the physical direction of the calculated results, as detailed below: For the vertically positioned first grinding wheel 110: the formula is calculated as follows Physically, this refers to the vertical height offset. The first adjusting component 200 drives the diamond wire 600 to move upwards along the vertical axis of the first grinding wheel 110. The distance allows the diamond wire 600 to avoid all previously formed old indentations in the vertical direction; for example, when entering the first zone 101 for the second time, the reference initial height of the first zone 101 is... The offset was calculated. =8mm, then the final working height of diamond wire 600 is +8mm, the vertical offset will not change the centering position of the diamond wire 600 in the first grinding gap, and will not affect the symmetry of the sharpening pressure.
[0068] For the second grinding wheel 310 with a horizontal setting: calculated by the formula Physically, this refers to the lateral offset in the horizontal direction. The second adjusting component 400 drives the diamond wire 600 to move to the right along the horizontal axis of the second grinding wheel 310. The distance allows the diamond wire 600 to avoid all previously formed old indentations in the horizontal direction; for example, when entering the second zone 102 for the second time, the reference initial horizontal position of the second zone 102 is... The offset was calculated. =8mm, then the final working horizontal position of the diamond wire 600 is Even with an 8mm offset in the horizontal direction, the alignment of the diamond wire 600 in the second grinding gap will not change, ensuring the stability of the sharpening pressure.
[0069] The offset of the two grinding wheels is calculated completely independently; the first grinding wheel has an offset of 110. The second grinding wheel 310 They can be different because the temperature and clamping force of the two grinding wheels may differ in their respective areas, and their offsets are accumulated independently without interference. Each time a cycle enters the corresponding area, the adjustment component determines the final working position of the diamond wire 600 based on the initial position of the corresponding area and the sum of all historical offsets, ensuring that it never overlaps with old indentations formed in any previous cycle.
[0070] Taking the first grinding wheel 110 as an example: Each time the loop returns to the target area, the adjuster determines the 600-degree height position of the diamond wire based on the initial position and historical offset of the target area: Upon entering Zone 101 for the Nth time: the adjustment component positions the diamond wire 600 at a certain height. ; Upon entering zone 102 for the Nth time: the adjustment component positions the diamond wire 600 at the height... ; Upon entering zone 3, 103 for the Nth time: the adjustment component brings the diamond wire 600 to a certain height. ; N is an integer greater than or equal to 1; This is the initial height on zone 101; This is the offset within zone 101; This is the initial height on zone 102; This is the offset within zone 102 of the second area; This is the initial height on zone 103; This is the offset within zone 103 of the third area.
[0071] Taking zone 101 as an example, when N=1, upon first entering zone 101, i.e., the initial state, the adjusting component brings the diamond wire 600 to a certain height. It landed exactly at the initial reference height, with no offset, which is consistent with the scenario of entering a scene without dents for the first time; When N=2, the second entry into zone 101 occurs, which is the return from the first cycle. The adjustment component brings the diamond wire 600 to a certain height. By adding one offset, the old dent left by the first polishing is just avoided; When N=3, the device enters the first zone 101 for the third time, which is the second time it returns from the loop. The adjustment component brings the diamond wire 600 to the height. By adding two offsets, the two old dents left by the previous two polishing were just avoided; When N=k, the kth time it enters the first zone 101, that is, the (k-1)th time it cycles back, and the adjustment component makes the diamond wire 600 reach the height. Accumulate k-1 offsets to avoid all k-1 historical indentations, ensuring permanent non-overlap; It is understandable that regarding the determination of N, that is, how to determine the number of cycles N, for example, the Nth time entering the first zone 101, in some embodiments, the adjustment component is driven by a servo motor: the servo motor outputs a positioning completion signal to confirm that the adjustment component has been in place, that is, triggers N to increment by 1. In other words, N is the global large cycle count, starting from 1; each time a complete cycle action of switching from the third zone 103 to the first zone 101 is completed, N is automatically incremented by 1, and N=1 when the device is initially powered on.
[0072] The technical solution of this application will be further described in detail below with reference to specific embodiments. This embodiment is applied to the sharpening process of 0.35mm photovoltaic diamond wire 600, and the specific implementation method is as follows: The grinding wheel used in this embodiment is a resin-rubber bonded grinding wheel with a total length of 900mm. It is vertically divided into three equal-length working areas from bottom to top, each area being 300mm long, with an initial height spacing of 300mm between adjacent areas. Each area is equipped with a temperature sensor, with a preset temperature threshold of 115℃. The grinding wheels are mounted opposite each other, and a cylinder pressure mechanism provides continuous clamping force. A pressure sensor is mounted on the grinding wheel mounting base, with a pressure acquisition accuracy of ±0.1N. The adjustment components consist of two opposite polyurethane adjustment wheels, which can move synchronously up and down via a servo motor after clamping the diamond wire 600. The pre-calibrated formula parameters are as follows: nominal diameter of diamond wire 600... =0.35mm, dent base extension =0.2mm, compressive force expansion coefficient =0.08mm / N, temperature expansion coefficient =0.01mm / ℃, room temperature is set to 25℃.
[0073] 1. Initial state (N=1, first entry into each region) After the equipment is started, the diamond wire 600 first stops at the initial height H1=0mm position of the first zone 101 and begins sharpening. At this time, N=1, and the total offset is the sum of the historical offsets from 1 to 0, that is, the offset is 0. The diamond wire 600 just falls on the reference initial position of the first zone 101 and begins sharpening.
[0074] When the temperature of Zone 101 rises to 115℃, reaching the preset temperature threshold, it indicates that Zone 101 has developed obvious dents. Continuing to grind will affect the sharpening effect. At this time, the control adjustment component moves the diamond wire 600 upward by 300mm, reaching the initial height H2=300mm position of Zone 102, and enters Zone 102 for grinding. Zone 101 stops working and begins to cool naturally.
[0075] When the temperature of the second zone 102 rises to 115℃, the control adjustment component drives the diamond wire 600 to move upward by 300mm, reaching the initial height H3=600mm position of the third zone 103, and enters the third zone 103 for grinding. The second zone 102 then exits the work and begins to cool naturally.
[0076] 2. Second entry into Zone 101 (N=2, second entry into each zone) When the temperature in zone 103 rises to 115℃, the cycle return action is triggered. At this time, the real-time temperature of zone 101 is 30℃ (fully cooled), and the grinding wheel clamping force is 18N. Calculate the offset of zone 101 in this instance: The dent is formed when grinding reaches 115℃, therefore the temperature rise is the difference between the working temperature and the room temperature: △T = 115℃ - 25℃ = 90℃. Substitute this into the offset formula to calculate: =5.43mm; The adjusting component moves the diamond wire 600 downwards by 600mm back to the initial height H1=0mm of the first zone 101, then shifts upwards by 5.43mm, finally stopping at the position of 0+5.43=5.43mm, completely avoiding the old dents formed by the first grinding, and begins the second grinding.
[0077] The same steps are used for the subsequent return cycles of Zone 102 and Zone 103: the offset is calculated based on the working temperature and current clamping force of the target area during grinding, and added to the historical offset sum of the corresponding area to ensure that the diamond wire 600 always avoids all historical old indentations.
[0078] 3. Entering Zone 101 for the kth time (N=k, multiple loops) As the number of iterations increases, the total offset of each region continues to accumulate. Taking region 101 as an example, the final working height of the diamond wire 600 upon the kth entry is: Where a1i is the offset of the i-th cycle of the first zone 101. The offset is dynamically calculated according to the current working condition each time, and the total offset continues to increase after accumulation.
[0079] This application also provides a diamond wire 600 processing device, including orthogonally arranged double grinding components, double adjusting parts and movable adjusting wheel 500; The first grinding assembly 100 includes two parallel and opposing first grinding wheels 110, with a first grinding gap between the two grinding wheels 110 for the diamond wire 600 to pass through. This gap is used to grind and sharpen the upper and lower sides of the diamond wire 600. The first grinding wheels 110 are arranged vertically. A first adjusting member 200 is disposed on the side of the first grinding wheel 110 and employs a double polyurethane roller clamping structure. This member is used to move the diamond wire 600 vertically and adjust the contact position of the diamond wire 600 on the first grinding wheel 110 without damaging the diamond abrasive grains on the surface of the diamond wire 600.
[0080] The second grinding assembly 300 includes two parallel and opposing second grinding wheels 310, with a second grinding gap between the two grinding wheels 310 for the diamond wire 600 to pass through. This gap is used to grind and sharpen the left and right sides of the diamond wire 600. The second grinding wheels 310 are arranged horizontally, perpendicular to the vertical direction. A second adjusting member 400 is disposed on the side of the second grinding wheel 310, also employing a double polyurethane roller clamping structure. This member is used to move the diamond wire 600 horizontally and adjust its contact position on the second grinding wheel 310.
[0081] The adjusting wheel 500 is mounted on the servo slide and has a degree of freedom of movement in the vertical direction. The diamond wire 600 is driven around the adjusting wheel 500 to adjust the wire tension of the diamond wire 600. The arrangement of orthogonal double grinding wheels enables the diamond wire 600 to be fully sharpened in 360°. The active pre-compensation of the adjusting wheel 500 enables smooth and shock-free position adjustment. The overall structure is simple.
[0082] The first grinding wheel 110 and the second grinding wheel 310 are each divided into three equal-length working areas along the axial direction, namely the first area 101, the second area 102 and the third area 103 from the reference end. A temperature sensor is independently set at the center of each working area to realize independent temperature monitoring of the three areas and ensure accurate temperature acquisition of each area.
