Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of diamond wire multi-wire cutting, and particularly relates to a method for adjusting diamond wire cable-stayed in real time based on gas medium breakdown. BACKGROUND

[0002] The slicing machine comprises a wire releasing cabin, a wire collecting cabin and a processing cabin. The processing cabin has left and right main rollers and a lower main roller, and the main rollers are provided with a plurality of groups of wire grooves. The diamond wire is arranged in a right-handed manner through staggered arrangement in different main roller wire grooves, and the silicon rod is cut in a forward and reverse manner through forward and reverse rotation of the wire releasing and collecting rollers. Three groups of servo motor systems for controlling the main rollers ensure that the wire releasing and collecting rollers rotate at the same wire speed, so that the diamond wire stably cuts the silicon rod under constant tension.

[0003] In the implementation of the wire releasing and collecting process, each forward and reverse rotation cycle is taken as a unit, and the wire releasing amount is greater than the wire collecting amount as a process condition to cut the silicon rod. However, because the tension applied to the diamond wire by the main roller during cutting is greater than the tension of the wire roller during winding, the wire roller winding tension is unstable, which causes the diamond wire to be not perpendicular to the inclined surface of the wire roller and the synchronous guide wheel, and the cable-stayed phenomenon occurs.

[0004] In view of the above cable-stayed phenomenon, the prior art is to passively predict the cable-stayed phenomenon through the offset of the tension wheel in the wire releasing cabin of the slicing machine or the offset of the tension wheel in the wire collecting cabin of the slicing machine, and then correct the offset through a synchronous device, so as to ensure the perpendicularity of the diamond wire.

[0005] However, the above prior art has the following disadvantages: because the detection accuracy of the tension wheel is not enough and there is a detection time delay, the cable-stayed phenomenon cannot be discovered and effectively corrected in time, so the cable-stayed phenomenon still occurs when the slicing machine cuts the silicon rod. SUMMARY

[0006] In order to overcome the shortcomings of the prior art, the present application provides a method for adjusting diamond wire cable-stayed in real time based on gas medium breakdown, which is used to solve the technical problem that the prior art cannot discover and effectively correct the cable-stayed phenomenon of the diamond wire in time, so as to achieve the purposes of accurate detection, rapid identification of the cable-stayed phenomenon of the diamond wire, and rapid and effective correction of the cable-stayed phenomenon of the diamond wire.

[0063] The method for real-time adjustment of the inclined pull of the diamond wire based on the gas medium breakdown provided by the present application, as shown in the figure, comprises the following steps: Figure 1

[0064] Step S1: Obtain the position of the diamond wire 1 between the synchronous guide wheel 4 and the line roller 5 when no deviation occurs, and set a left detection device 2 on the left side of the diamond wire 1 and a right detection device 3 on the right side of the diamond wire 1;

[0065] Step S2: Form a left discharge area on the left side of the diamond wire 1 through the left detection device 2, and form a right discharge area on the right side of the diamond wire 1 through the right detection device 3;

[0066] Step S3: Start the slicing machine to cut the silicon rod, and the diamond wire 1 between the synchronous guide wheel 4 and the line roller 5 starts to appear inclined and constantly approaches the left discharge area or the right discharge area;

[0067] Step S4: When the diamond wire 1 enters the left discharge area, the left detection device 2 will send a right deviation pulse signal through the signal module;

[0068] Step S5: After the servo motor device 6 on the synchronous guide wheel 4 receives the right deviation pulse signal, the synchronous guide wheel 4 is controlled to move left until the diamond wire 1 leaves the left discharge area;

[0069] Step S6: When the diamond wire 1 enters the right discharge area, the right detection device 3 will send a left deviation pulse signal through the signal module;

[0070] Step S7: After the servo motor device 6 on the synchronous guide wheel 4 receives the left deviation pulse signal, the synchronous guide wheel 4 is controlled to move right until the diamond wire 1 leaves the right discharge area.

[0071] In the above step S2, when forming a left discharge area on the left side of the diamond wire 1 through the left detection device 2, it includes:

[0072] According to the preset distance between the plates, the first left plate 7 and the first right plate 8 are arranged in parallel on the left side of the diamond wire 1;

[0073] And according to the preset distance between the plates, a maximum breakdown voltage is determined;

[0074] According to the maximum breakdown voltage, the first left plate 7 and the first right plate 8 are energized to form a left discharge area between the first left plate 7 and the first right plate 8;

[0075] Among them, the left detection device includes: the first left plate 7 and the first right plate 8.

[0076] In the above step S2, when forming a right discharge area on the right side of the diamond wire 1 through the right detection device 3, it includes:

[0077] According to the preset distance between the plates, the second left plate and the second right plate are arranged in parallel on the right side of the diamond wire 1;

[0078] And according to the preset inter-plate distance to determine a maximum breakdown voltage;

[0079] According to the maximum breakdown voltage, the second left plate and the second right plate are energized, and a right discharge region is formed between the second left plate and the second right plate;

[0080] The right detection device 3 comprises a second left plate and a second right plate.

[0081] The implementation principle of the present application is as follows:

[0082] The gas medium breakdown principle is used to detect whether the diamond wire 1 is deviated, so as to realize the synchronous adjustment of the synchronous guide wheel 4. The gas medium breakdown principle is that the gas medium is ionized by collision under the action of an electric field, and the phenomenon of through discharge between electrodes is caused. The present application detects whether the diamond wire 1 is deviated through a parallel plate capacitor device composed of two mutually parallel and close metal plates. When the plates are charged, the internal electric field is a uniform electric field, and the breakdown voltage in the uniform electric field is shown in formula 1. When the diamond wire 1 does not enter the plate discharge region, the two plates are in an inductance state.

[0083] According to the actual design needs, the distance L between the two plates is 25±1mm, the diamond wire 1 enters the two-plate discharge region along the center extension line of the two plates, and when the set voltage is higher than a certain degree (the maximum breakdown voltage), the two plates break down the air at both ends of the diamond wire 1 to form a loop through the diamond wire 1. At this time, the on-off detector detects that the diamond wire 1 deviates, as shown in Figure 2 .

[0084] In the use process of the diamond wire 1, the diamond wire 1 will move from the positive direction to the negative direction on the Y axis due to the decrease of the wire amount on the wire roller 5. In order to avoid the diamond wire 1 directly touching the plate during the movement process, the extreme value of the diamond wire movement interval range is limited, as shown in Figure 3 .

[0085] Generally, when the distance L between the two plates is 25±1mm, the extreme value O of the diamond wire movement interval range is 7.5mm, and according to formula 2, the maximum distance that needs to be broken down to make the two plates conductive can be obtained.

[0086] When the diamond wire 1 is at the extreme value, the diamond wire 1 needs to satisfy the conduction of the two plates, and the maximum distance that needs to be broken down is shown in formula 3, and the maximum breakdown voltage is shown in formula 4.

[0087] In formula 1 and formula 4, the relative air density δ is generally taken as 1.29Kg / m 3 .

[0088] The edges of the synchronization guide wheel 4 on both sides will also be worn during use, but the wear of the synchronization guide wheel 4 will be less than the decrease in the Y-axis direction when the wire roller 5 is paying out wire, so the compensation amount required to correct the wear of the synchronization guide wheel 4 is covered by the formula 4 at this point and does not need to be described separately.

[0089] After the maximum breakdown voltage is determined, the electrode plates are energized according to the maximum breakdown voltage to form left and right discharge regions. When the diamond wire 1 is outside the electrode plates, the electrode plates are not conductive, and when the diamond wire enters the electrode plates due to the catenary, the electrode plates are conductive. Therefore, whether the diamond wire 1 has a catenary phenomenon can be determined according to whether the electrode plates are conductive, and after the catenary is conductive, the signal module will output the related pulse signal, and the servo motor device 6 on the synchronization guide wheel 4 will automatically correct the deviation after receiving the signal, as shown in Figure 4 .

[0090] In the above step S3, when the diamond wire 1 continuously approaches the left or right discharge region, it includes:

[0091] According to the preset distance between the electrode plates, a maximum value of the diamond wire movement interval range is obtained, and the movement range of the diamond wire 1 in the Y-axis direction is limited according to the maximum value of the diamond wire movement interval range.

[0092] In the above step S2, when a maximum breakdown voltage is determined according to the preset distance between the electrode plates, it includes:

[0093] The breakdown voltage is determined according to the preset distance between the electrode plates, the relative air density, and the distance between the outer edge of the diamond wire cylinder and the electrode plate, as shown in formula 1:

[0094]

[0095] In the formula, U b is the breakdown voltage (kv), δ is the relative air density, and d is the distance between the outer edge of the diamond wire cylinder and the electrode plate (cm).

[0096] Further, when a maximum breakdown voltage is determined according to the preset distance between the electrode plates, it further includes:

[0097] The distance between the outer edge of the diamond wire cylinder and the electrode plate is determined according to the preset distance between the electrode plates, the maximum value of the diamond wire movement interval range, and the diameter of the diamond wire, as shown in formula 2:

[0098]

[0099] In the formula, L is the preset distance between the electrode plates, O is the maximum value of the diamond wire movement interval range, and D is the diameter of the diamond wire.

[0100] ​Further, when determining the maximum breakdown voltage according to the preset inter-electrode distance, the method further comprises:

[0101] The maximum breakdown distance required when the diamond wire 1 is at the extreme value is obtained, and is specifically shown in formula 3:

[0102]

[0103] In the formula, d max is the maximum breakdown distance.

[0104] Further, when determining the maximum breakdown voltage according to the preset inter-electrode distance, the method further comprises:

[0105] According to the maximum breakdown distance and formula 1, the maximum breakdown voltage is determined, and is specifically shown in formula 4:

[0106]

[0107] In the formula, U bmax is the maximum breakdown voltage.

[0108] In the above step S5, when the servo motor device 6 controls the synchronous guide wheel 4 to move left (to the negative direction of the X axis), the method comprises:

[0109] Taking 50 ms as an adjustment period and 0.5 mm as the moving amount each time, the synchronous guide wheel 4 is controlled by the servo motor device 6 to move left, and the first continuity detector 9 is constantly detected until the diamond wire 1 is separated from the left discharge area;

[0110] The left detection device 2 comprises the first continuity detector 9.

[0111] Specifically, the definition of the right deviation in the present application is specifically shown in formula 2. Figure 5

[0112] In the above step S7, when the servo motor device 6 controls the synchronous guide wheel 4 to move right (to the positive direction of the X axis), the method comprises:

[0113] Taking 50 ms as an adjustment period and 0.5 mm as the moving amount each time, the synchronous guide wheel 4 is controlled by the servo motor device 6 to move right, and the second continuity detector is constantly detected until the diamond wire 1 is separated from the right discharge area;

[0114] The right detection device 3 comprises the second continuity detector.

[0115] Specifically, the definition of the left deviation in the present application is specifically shown in formula 1. Figure 5

[0116] ​​Specifically, the present application sets the adjustment unit of the servo motor device 6 to 0.5 mm because of high detection frequency, short detection time and fast adjustment time.

[0118] (1) The present application sets left and right detection devices on the left and right sides of the diamond wire respectively, and when the diamond wire is right-biased on the wire roller, the left detection device can detect it, and when the diamond wire is left-biased on the wire roller, the right detection device can detect it, so as to realize accurate detection of the diamond wire in different directions, and thus accurately and effectively correct the diamond wire;

[0119] (2) The detection device of the present application uses the gas medium breakdown principle to detect whether the diamond wire is biased, and as long as the diamond wire is tilted and enters the discharge area, breakdown will occur immediately to make the electrode plate conductive, so as to be detected by the on-off detector, prompting the signal module to send a corresponding pulse signal. The detection method of the present application has higher detection accuracy compared with the prior art which detects the tilt by using the tension wheel, and basically does not have detection time delay;

[0120] (3) After the detection device detects that the diamond wire is tilted, the signal module sends a corresponding pulse signal in the first time, and after the servo motor device on the synchronous guide wheel receives the pulse signal, it immediately controls the synchronous guide wheel to move correspondingly, so as to effectively and timely correct the tilt of the diamond wire;
