Description

Technical Field

[0001] The utility model belongs to the technical field of material support devices, and particularly relates to a floating support. Background Art

[0002] When cutting a silicon crystal rod, generally, multiple supporting devices are evenly distributed directly below the silicon crystal rod along the axis direction of the silicon crystal rod to support the silicon crystal rod and accurately move the silicon crystal rod to the cutting position for cutting.

[0003] At present, the market usually uses a locking cylinder with a corresponding moving mechanism as a supporting device to support and move the silicon crystal rod. However, in actual use, it is found that when the supported material is a long silicon crystal rod with a small diameter fluctuation (i.e., approximately cylindrical), as shown in the attached manual, Figure 1 As shown in the figure, the axis of the silicon crystal rod placed on the support assembly is relatively parallel to the conveying direction of the silicon crystal rod, and the influence of the silicon crystal rod cutting tilt is small and within the allowable range of processing error; when the supported material is a short silicon crystal rod with a large diameter variation (i.e., it is similar to a truncated cone with inconsistent dimensions at both ends), as shown in the attached manual Figure 2 As shown in the figure, since the conventionally used support components, such as the locking cylinder, stop after the lifting touches the silicon rod, it is impossible to sense the inclination of the silicon rod and further adjust it, so that the axis of the silicon crystal rod placed on the support component is easy to form an angle with the conveying direction of the silicon crystal rod, so that in actual processing, only the angle specified in the specification can be achieved. Figure 2 and attached Figure 3 The supporting state in the instruction manual cannot be realized Figure 4 and attached Figure 5 The ideal supporting effect in the silicon crystal rod causes the cut section to form an angle with the axis of the silicon crystal rod, that is, the cut section is elliptical, and the ingot cutting has a great influence, which in turn has a serious impact on the subsequent processing accuracy of the silicon crystal rod.

[0064] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0065] The most critical concept of the utility model is: utilizing the centering characteristics of the recessed structure and the protrusion and setting the micro-motion sensor in the gap between the two, the triggering error rate of the micro-motion sensor can be reduced, so that the micro-motion sensor can accurately feedback the position of the contacted bar material, so as to provide structural support for the adjustment of the bar material position, and then compensate for the material lifting stroke, so as to solve the problem that silicon rods, especially short rods, are easily cut obliquely.

[0066] Please refer to Figures 6 to 8 The floating support provided by the utility model comprises a telescopic device 5 and a micro-motion sensor 6, and the movable end of the telescopic device 5 is elastically connected with a movable block 51;

[0067] The end of the movable block 51 opposite to the movable end of the telescopic device 5 is provided with a recessed structure 511;

[0068] The movable end of the telescopic device 5 is provided with a convex block 52 adapted to the concave structure 511;

[0069] A preset distance between the recessed structure 511 and the protrusion 52 forms a gap 53;

[0070] The sensing end of the micro-motion sensor 6 is disposed in the gap 53 .

[0071] Specifically, the recessed depth of the recessed structure 511 is less than or equal to the raised height of the protrusion 52, thereby effectively solving the problem that there is still a slight gap between the corresponding position of the movable block 51 and the micro-motion sensor 6 due to size mismatch or angle deviation, and the micro-motion sensor 6 cannot be triggered to record the height of the material.

[0072] From the above description, it can be seen that the beneficial effects of the utility model are: providing a floating support, utilizing the effect of the mutual centering cooperation of the recessed structure 511 and the protrusion 52, and setting the micro-motion sensor 6 in the gap between the recessed structure 511 and the protrusion 52, the triggering error rate of the micro-motion sensor 6 can be reduced, so that the micro-motion sensor 6 can accurately feedback the position of the contacted rod; compared with the existing floating support, the existing floating support stops moving at the moment of lifting and contacting the silicon crystal rod. If the horizontality of the silicon crystal rod does not meet the processing conditions, then the existing floating support will still allow the silicon crystal rod to move to the subsequent cutting station in an incorrect posture after supporting the silicon crystal rod, thereby causing the cross-sectional shape of the silicon crystal rod after cutting to fail to meet the design requirements; and the floating support of the utility model can record the height information of the material through the micro-motion sensor 6, so as to use multiple height information to further realize the correction function of the rod angle, that is, to compensate for the material lifting stroke, so as to solve the problem that the silicon rod, especially the short rod, is easy to cut obliquely.

[0073] Furthermore, the contact surface between the recessed structure 511 and the bump 52 , and the contact surface between the bump 52 and the recessed structure 511 are both spherical surfaces.

[0074] From the above description, it can be seen that by further utilizing the characteristic that the spherical structure has equal distances from each point on the surface to the center, the contact surfaces of the recessed structure 511 and the protrusion 52 are both set to spherical surfaces, that is, when the movable block 51 is tilted at any angle, it can be better ensured that any shortest distance from the recessed structure 511 to the protrusion 52 is equal; ensuring that the micro-motion sensor 6 can be triggered and sensed by the movable block 51, thereby avoiding the problem of failure to trigger the micro-motion sensor 6 or delay in triggering the micro-motion sensor 6 due to deviation between the supporting position of the material and the movable block 51, thereby distorting the material height value recorded by the micro-motion sensor 6, and ultimately affecting the subsequent processing accuracy.

[0075] Furthermore, the changing direction of the gap 53 is parallel to the telescopic direction of the telescopic device 5 .

[0076] From the above description, it can be seen that this design ensures that at a certain moment when the telescopic device 5 drives the micro-motion sensor 6 to move towards the material, it can trigger the micro-motion sensor 6 through the movable block 51 to record the actual height of the material, thereby ensuring that the subsequent inclination adjustment of the material can be carried out normally.

[0077] Furthermore, a support block 54 is provided at the movable end of the telescopic device 5;

[0078] The support block 54 is a hollow structure;

[0079] The movable block 51 is elastically connected to the supporting block 54;

[0080] The protrusion 52 is disposed on the supporting block 54, and the protrusion 52 is disposed opposite to the recessed structure 511;

[0081] The micro-motion sensor 6 is disposed inside the support block 54;

[0082] The sensing end of the micro-motion sensor 6 passes through the protrusion 52 and is disposed toward the recessed structure 511 .

[0083] Specifically, the outer side wall of the micro-motion sensor 6 is threadedly connected to the support block 54 , and this connection can effectively improve the efficiency of disassembly and assembly of the micro-motion sensor 6 .

[0084] From the above description, it can be seen that the design has made specific improvements to the connection relationship between the telescopic device 5, the micro-motion sensor 6 and the movable block 51, and the micro-motion sensor 6 is set inside the hollow support block 54, which can not only effectively fix the micro-motion sensor 6 to avoid affecting the height detection accuracy of the material due to shaking during use, but also protect the micro-motion sensor 6, thereby extending the service life of the micro-motion sensor 6.

[0085] Furthermore, a portion of the sensing end of the micro-motion sensor 6 is exposed outside the protrusion 52;

[0086] The exposed portion of the sensing end of the micro-motion sensor 6 is arranged at the highest point of the protrusion 52 .

[0087] From the above description, it can be seen that the design has further optimized the requirements for the position distribution of the sensing end of the micro-motion sensor 6. The sensing end of the micro-motion sensor 6 is set at the highest point of the protrusion 52, so that the movable block 51 can trigger the micro-motion sensor 6 at the first time when approaching the protrusion 52, thereby ensuring that the micro-motion sensor 6 can accurately record the actual height of the material, thereby providing accuracy guarantee for the subsequent processing of the material.

[0088] Furthermore, the above-mentioned floating support further comprises at least two elastic elements 7;

[0089] The elastic elements 7 are evenly distributed on the outer side of the protrusion 52 in the circumferential direction;

[0090] The movable block 51 is elastically connected to the supporting block 54 via the elastic element 7;

[0091] The telescopic direction of the elastic element 7 is parallel to the telescopic direction of the telescopic device 5 .

[0092] Specifically, the elastic element 7 is any commercially available structure that has a certain elasticity and can automatically restore after the external force is removed, such as a coil spring.

[0093] From the above description, it can be known that the elastic element 7 provides structural support for the elastic connection between the movable block 51 and the support block 54, ensuring that the material can trigger the micro-motion sensor 6 through the movable block 51 at the moment of contact with the movable block 51 to accurately record the height of the material. At the same time, after the material is removed from the floating support, the elastic element 7 can quickly separate the movable block 51 from the micro-motion sensor 6, thereby preparing for the next material support and inclination adjustment work.

[0094] Furthermore, the above-mentioned floating support further includes a sealing ring 8;

[0095] A stopper 541 is provided on the outer circumference of the support block 54;

[0096] The movable block 51 is a cover-like structure with one end closed and the other end open;

[0097] The open end of the movable block 51 is disposed toward the supporting block 54;

[0098] The outer wall of the limiting member 541 is slidably connected to the inner wall of the movable block 51;

[0099] The sealing ring 8 is arranged inside the movable block 51;

[0100] The sealing ring 8, the movable block 51 and the limiting member 541 form a sealing structure.

[0101] Furthermore, along the telescopic direction of the telescopic device 5, the two ends of the sealing ring 8 respectively conflict with the closed end of the movable block 51 and one end of the limiter 541 in the thickness direction;

[0102] Along a direction perpendicular to the telescopic direction of the telescopic device 5 , two ends of the sealing ring 8 respectively contact the inner wall of the movable block 51 and the outer wall of the supporting block 54 .

[0103] Specifically, the sealing ring 8 is any commercially available structure capable of achieving elastic deformation, such as a rubber sealing ring.

[0104] As can be seen from the above description, the design has made further improvements to the structure of the movable block 51 and the support block 54. By setting a limiter 541 on the outer side of the support block 54 and allowing the outer wall of the limiter 541 to be slidably connected to the inner wall of the movable block 51, it can play a guiding role for the movable block 51 in the process of moving relative to the support block 54, thereby effectively avoiding the triggering delay and the problem of failure to trigger caused by the movable block 51 tiltedly contacting the micro-motion sensor 6 or not contacting the micro-motion sensor 6 due to inaccurate contact position between the material and the movable block 51, thereby effectively improving the detection accuracy of the micro-motion sensor 6 for the material height; by setting a sealing ring 8 inside the movable block 51, and by the sealing ring 8, the movable block 51, the support block 54 and the limiter 541 cooperate to form a corresponding sealing structure, it can be avoided that the debris and dust generated by material processing enters the movable block 51, thereby affecting the starting sensitivity of the micro-motion sensor 6, and causing the detected material height value to be distorted.

[0105] Furthermore, a clamping member 512 is provided at the open end of the movable block 51;

[0106] In the telescopic direction of the telescopic device 5, the limiting member 541 is arranged between the sealing ring 8 and the clamping member 512;

[0107] Along the telescopic direction of the telescopic device 5, the clamping member 512 can be close to or away from the limiting member 541;

[0108] When the movable block 51 moves to the farthest point away from the supporting block 54 , the clamping member 512 abuts against the other end of the limiting member 541 in the thickness direction.

[0109] From the above description, it can be seen that when the material leaves the movable block 51, the movable block 51 will be separated from the support under the action of elasticity, so that the movable block 51 is away from the sensing end of the micro-motion sensor 6, and then prepares for the next material support, that is, the material height detection work. In order to prevent the movable block 51 from detaching from the support block 54 due to excessive movement, thereby affecting the subsequent normal work, a clamping member 512 that can interfere with the limiting member 541 is provided at the open end of the movable block 51, so as to limit the movable block 51 and achieve the effect of solving the above-mentioned problem.

[0110] Further, the telescopic device 5 includes a support plate 55, a threaded telescopic rod group 56 and a motor 57;

[0111] The threaded telescopic rod group 56 and the motor 57 are disposed on both sides of the support plate 55 in the thickness direction;

[0112] The support block 54 is connected to the movable end of the threaded telescopic rod set 56;

[0113] The motor 57 is in transmission connection with the movable end of the threaded telescopic rod set 56 to drive the support block 54 to reciprocate along the axial direction of the threaded telescopic rod set 56 .

[0114] Preferably, the motor 57 is a servo motor with high adjustment accuracy and sensitive response. Since the servo motor has an absolute encoder and a Z-axis origin, when the staff calibrates the horizontal position of the starting point of the two floating supports and sets the zero point, the two floating supports have the same contact induction. Similarly, after the absolute encoder is assigned an angle, the corresponding logical judgment can be made on the height values ​​of different positions of the subsequent bar.

[0115] From the above description, it can be seen that the design has made specific modifications to the composition structure of the telescopic device 5, so as to provide structural support for the micro-motion sensor 6 to be able to approach or move away from the material and trigger the micro-motion sensor 6 through the movable block 51; compared with the general motor 57, the servo motor has an absolute encoder, so it can adjust the output torque and speed according to external signals, and can accurately control the telescopic amount of the threaded telescopic rod group 56; when adjusting the inclination of the material, the servo motor is combined with the peripheral control system, so that corresponding logical judgment can be performed to realize the pre-judgment of the horizontality of the material, thereby adjusting the inclined material to a state that meets the processing conditions.

[0116] Furthermore, the threaded telescopic rod assembly 56 includes a positioning seat 561, and a transmission nut seat 562, a guide limit block 563 and a screw rod 564 arranged inside the positioning seat 561;

[0117] The positioning seat 561 has at least two guide limit grooves evenly distributed along the circumference of its inner wall;

[0118] The extending direction of the guide limit groove is parallel to the axial direction of the screw rod 564;

[0119] The motor 57 is in driving connection with the screw rod 564;

[0120] The screw rod 564 is threadedly connected to the transmission nut seat 562;

[0121] The transmission nut seat 562 is slidably connected to the guide limit groove via the guide limit block 563;

[0122] The micro-motion sensor 6 is disposed at an end of the transmission nut seat 562 away from the motor 57 .

[0123] From the above description, it can be seen that the design has made specific improvements to the composition structure of the threaded telescopic rod group 56. In the process of the motor 57 driving the screw 564 to rotate, due to the limiting effect of the guide limit groove and the guide limit block 563, the transmission nut seat 562 is prevented from rotating synchronously with the screw 564, and can only move back and forth along the extension direction of the guide limit groove, thereby smoothly driving the micro-motion sensor 6 to approach the material, so as to achieve the purpose of supporting and height detection of the material.

[0124] Furthermore, the above-mentioned floating support further comprises a corrugated protective cover 9;

[0125] The corrugated protective cover 9 is a cylindrical structure with openings at both ends;

[0126] The corrugated protective cover 9 is sleeved on the outer sides of the micro-motion sensor 6 and the threaded telescopic rod set 56 , and the two ends of the corrugated protective cover 9 are sealedly connected to the side wall of the micro-motion sensor 6 and the outer side wall of the threaded telescopic rod set 56 respectively.

[0127] As can be seen from the above description, since a large amount of dust and debris will be generated during the cutting process of the silicon crystal rod, in order to prevent processing waste from invading the inside of the micro-motion sensor 6 and the threaded telescopic rod group 56, thereby affecting the normal operation of the floating support, a corrugated protective cover 9 is provided on the outside of the micro-motion sensor 6 and the threaded telescopic rod group 56, which can achieve a better dust-proof effect; and because the floating support needs to intermittently telescope and move during operation, and the corrugated protective cover 9 has good scalability due to its own structure, while achieving the dust-proof effect, it can not only change its own state with the telescopic amount of the floating support, thereby avoiding the problem of tearing damage and loss of dust-proof function due to lack of variability; it can also play a certain buffering role when the threaded telescopic rod group 56 retracts to prevent rigid impact.

[0128] Furthermore, the above-mentioned floating support further includes a lower limit sensor 10 and a sensor sheet 11;

[0129] The lower limit sensor 10 is connected to one side of the support plate 55 where the threaded telescopic rod group 56 is provided, and the sensing end of the lower limit sensor 10 is arranged toward the threaded telescopic rod group 56;

[0130] The induction piece 11 is connected to the movable end of the threaded telescopic rod set 56, and the induction piece 11 can reciprocate along the axial direction of the threaded telescopic rod set 56;

[0131] The sensing end of the lower limit sensor 10 is located on the moving path of the sensing sheet 11;

[0132] The lower limit sensor 10 is electrically connected to the motor 57 .

[0133] From the above description, it can be seen that this design provides a safety measure. If a fault occurs in the motor 57, causing the motor 57 to drive the threaded telescopic rod group 56 to move down to the specified position, but still cannot stop running, the lower limit sensor 10 is triggered by the sensor sheet 11, and a forced stop signal can be sent to the external controller, and then sent to the motor 57 by the controller, thereby forcibly shutting down the motor 57 to prevent damage to the equipment.

[0134] Furthermore, the above-mentioned floating support further includes a V-shaped block 12;

[0135] The V-shaped block 12 is connected to one end of the movable block 51 away from the supporting block 54;

[0136] The open end of the V-shaped block 12 is arranged toward the extending direction of the movable end of the telescopic device 5 .

[0137] From the above description, it can be seen that by providing a V-shaped block on the movable block 51, the stability of the floating support when supporting materials can be improved to prevent the materials from falling off the floating support due to shaking during the lifting process, thereby seriously affecting the overall processing efficiency.

[0138] The floating support of the utility model can assist in supporting materials, especially supporting silicon crystal rods that need to be cut; the existing floating support moving mechanism can also be combined to be applied to existing products such as the support of silicon rods in multi-station cutting machines, such as being used for supporting silicon rods in a multi-station cutting machine disclosed in the Chinese utility model application No. 202023080931.7.

[0149] The above-mentioned floating support also includes a lower limit sensor 10 and a sensing sheet 11; the lower limit sensor 10 is connected to one side of the support plate 55 where a threaded telescopic rod group 56 is provided, and the sensing end of the lower limit sensor 10 is arranged toward the threaded telescopic rod group 56; the sensing sheet 11 is connected to the movable end of the threaded telescopic rod group 56, and the sensing sheet 11 can reciprocate along the axial direction of the threaded telescopic rod group 56; the sensing end of the lower limit sensor 10 is located on the moving path of the sensing sheet 11; the lower limit sensor 10 is connected to the motor 57 through a controller.

[0150] The above-mentioned floating support further includes a V-shaped block 12 ; the V-shaped block 12 is connected to one end of the movable block 51 away from the supporting block 54 ; the open end of the V-shaped block 12 is arranged toward the extending direction of the movable end of the telescopic device 5 .

[0151] The working principle of the utility model is as follows: first, the staff will uniformly calibrate the floating supports to be used to correct the inclination of the silicon crystal rod, ensuring that the floating supports used are all in the same horizontal position under the zero-point state, in preparation for the subsequent judgment of whether the silicon crystal rod is tilted; then, the silicon crystal rod to be cut is moved to the approximate cutting position through the peripheral roller frame, and then the floating support is controlled by the peripheral control system to move to the jacking position, and it is ensured that floating supports are provided on both sides of the cut-off position of the silicon crystal rod; then, the screw rod 564 is driven to rotate by the motor 57, and with the cooperation of the guide limit groove and the guide limit block 563, the transmission nut seat 562 drives the micro-motion sensor 6 to move toward the outer side surface of the silicon crystal rod along the axial direction of the screw rod 564; when the movable block 51 contacts the outer cylindrical surface of the silicon crystal rod, under the action of the threaded telescopic rod group 56, the gap 53 between the recessed structure 511 and the protrusion 52 gradually shrinks until the movable block 51 touches the micro-motion sensor 6 on the support block 54, and the screw The telescopic rod group 56 continues to extend a certain distance toward the silicon crystal rod to offset the extension of the micro-motion sensor 6 exposed outside the protrusion 52, so that the gap 53 between the recessed structure 511 and the protrusion 52 can be completely eliminated, so that the silicon crystal rod and the floating support are in a rigid connection state. At this time, the floating supports arranged on both sides of the truncation position of the silicon crystal rod respectively send the recorded height information to the peripheral control system for data comparison. When the elongation of the two floating supports is equal, the elongation of the two is maintained, that is, the material support work is completed; when the elongation of the two floating supports is inconsistent, the peripheral control system first records the height difference between the two, and then keeps the floating support with a larger elongation unchanged, and then the floating support with a smaller elongation continues to extend to the same horizontal height as the floating support with a larger elongation, and then continues to compensate for the height difference between the two previously recorded, that is, the material support correction work is completed; finally, the floating support continues to drive the silicon crystal rod to move accurately to the cutting position, and the subsequent cutting operation can be carried out. If necessary, an additional floating support may be provided directly below the silicon crystal rod along the axial direction of the silicon crystal rod to improve stability during cutting.

[0152] In summary, the floating support provided by the utility model is different from the existing floating support. The existing floating support stops moving at the moment when it is lifted and touches the silicon crystal rod. If the horizontality of the silicon crystal rod does not meet the processing conditions, the existing floating support will still allow the silicon crystal rod to move to the subsequent cutting station in a wrong posture after supporting the silicon crystal rod, thereby causing the cross-sectional shape of the silicon crystal rod after cutting to fail to meet the design requirements. The floating support of the utility model can not only record the height information of the material through the micro-motion sensor, and send the relevant information to the peripheral control system for data comparison to realize the automatic correction function of the material angle, but also utilize the spherical structure with the characteristic of equal distance from each point on the surface to the center. , the contact surfaces of the recessed structure and the protrusion are both set to spherical surfaces, that is, when the movable block is tilted at any angle, it can better ensure that any shortest distance from the recessed structure to the protrusion is equidistant, thereby solving the problem of failure to trigger the micro-motion sensor or delay in triggering the micro-motion sensor due to deviation in the supporting position of the material and the movable block, thereby avoiding distortion of the material height value recorded by the micro-motion sensor. Even if there is a deviation in the contact position between the material and the floating support, resulting in a slight offset of the movable block, the movable block can still accurately trigger the micro-motion sensor, thereby ensuring the authenticity of the material height collected by the floating support, thereby improving the subsequent processing accuracy of the material; at the same time, it can also make the micro-motion sensor evenly stressed to reduce wear.
