Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicon rod processing, specifically relates to a kind of eight-inch silicon rod stick positioning with the drive assembly of easy maintenance. BACKGROUND

[0002] The processing of silicon rod is a crucial link. Before entering actual processing procedure, stick handling is an indispensable pre-step. The accuracy of stick has a decisive influence on the quality and production efficiency of subsequent silicon wafer. In order to ensure the accuracy of silicon rod stick, accurate detection is carried out on the outer circumferential surface of silicon rod. In the detection process, silicon rod needs to be driven to rotate in order to comprehensively and accurately obtain various data of the outer circumferential surface of silicon rod. This depends on a special drive assembly to realize the rotation of silicon rod.

[0003] In the existing drive assembly, the drive protective sleeve is an important component. In the process of driving silicon rod to rotate, due to the friction and mechanical action between silicon rod and other components, wear and tear will inevitably occur. With the increase of use time and use frequency, the degree of wear and tear of the protective sleeve will gradually increase. When it is worn to a certain extent, it can no longer provide effective protection for the drive assembly, thereby affecting the normal operation of the drive assembly and the stability and accuracy of the rotation of silicon rod. Therefore, in order to ensure the performance of the drive assembly and the accuracy of silicon rod detection, the worn protective sleeve often needs to be replaced.

[0004] At the same time, the base included in the existing drive assembly plays an important role in supporting and positioning silicon rod in the whole system. In order to ensure that the subsequent support and positioning effect of silicon rod can meet the production requirements, multiple accurate measurements need to be carried out when the base is installed and positioned. This is because only through multiple measurements and adjustments can the position and angle of the base be ensured to be accurate, so that the silicon rod can remain stable during rotation, avoiding deviation or shaking and other situations, which affect the detection results of the outer circumferential surface of silicon rod and the accuracy of stick.

[0005] However, when the drive protective sleeve needs to be replaced, due to the close connection between the base and other parts of the drive assembly, the existing design requires the base to be disassembled every time the protective sleeve is replaced. Once the base is disassembled, it needs to be repositioned, which means that tedious multiple measurement work needs to be done again. This operation method undoubtedly greatly increases the workload of workers, making the equipment maintenance process complex and time-consuming. Moreover, frequent disassembly and repositioning of the base may cause damage to the base itself and other components connected to it to some extent, further affecting the performance and service life of the equipment. At the same time, it reduces the work efficiency of equipment maintenance, prolongs the downtime of the equipment, and thus affects the production progress and capacity of the whole silicon rod processing production line, increasing the production cost.

DETAILED DESCRIPTION

[0025] In order to better understand the utility model, the contents of the utility model are further illustrated below in conjunction with examples, but the contents of the utility model are not limited to the following examples.

[0026] As shown in Figure 3, a kind of eight-inch silicon rod stick positioning with maintenance driven assembly for stick, same as prior art, it has displacement assembly 8 that can adjust the position of connecting base 1, lay foundation for subsequent silicon rod 9 positioning detection work.Connecting base 1 is positioned and supported stably on displacement assembly 8 by fixed support plate 2 and movable support plate 5, and specific positioning support point is located at the position of protective sleeve 7 on bearing shaft 6.On two displacement assemblies 8, four protective sleeves 7 are symmetrically distributed, when two displacement assemblies 8 are adjusted, protective sleeve 7 can synchronously hold up silicon rod 9.At the same time, fixed support plate 2 is equipped with driving piece 10, after driving piece 10 is started, bearing shaft 6 can be rotated, and then protective sleeve 7 is synchronously rotated, to realize accurate, comprehensive positioning detection to the outer circumferential surface of silicon rod 9.

[0027] In the process of positioning bearing shaft 6 and protective sleeve 7 to displacement assembly 8, there is rigorous operation process.Firstly, connecting base 1 and fixed support plate 2 are firmly fixed and connected using screw, to ensure that stable structure whole is formed between the two.Then, movable support plate 5 is connected using connecting piece 4 and locking piece 3 on connecting base 1.In this step, the position of movable support plate 5 needs to be accurately adjusted, to ensure that the cooperation between movable support plate 5, fixed support plate 2 and connecting base 1 is accurate and faultless.Finally, the whole structure is debugged, after each parameter meets the requirements, connecting base 1 is fixed on displacement assembly 8.Through this series of operations, high-precision positioning of bearing shaft 6 and protective sleeve 7 is realized, to provide reliable guarantee for silicon rod 9 test, and ensure that silicon rod 9 test positioning effect reaches the optimum.

[0028] As shown in FIG. 1 and FIG. 2, the connecting base 1 adopts a T-shaped design. The horizontal surface of the connecting base 1 is connected to the displacement assembly 8 through bolts, which is not only stable and reliable, but also convenient to disassemble and install, providing convenience for subsequent maintenance work. The connecting piece 4 includes a sliding groove 401 opened at the center of the vertical section of the connecting base 1. In the sliding groove 401, a connecting column 405 that can slide is arranged, and a matching column 403 is arranged vertically with the connecting column 405. The two ends of the matching column 403 pass through the sliding groove 401 and exceed the edge of the connecting base 1, corresponding to the pressing plate 302 in the locking piece 3. The pressing plate 302 is rotationally connected to the support shaft 305 on the vertical section of the connecting base 1. On the side of the pressing plate 302 facing the connecting base 1, an inclined part 304 is designed, and the higher end of the inclined part 304 is in communication with the limiting groove 303 on the pressing plate 302. When the pressing plate 302 is rotated downward to press the matching column 403, under the auxiliary action of the inclined part 304, the matching column 403 drives the connecting column 405 to move to the inside of the sliding groove 401 until the matching column 403 completely enters the limiting groove 303. At this time, the connecting column 405 will drive the movable support plate 5 rotationally connected thereto to tightly contact the connecting base 1. In this process, the worker can make appropriate auxiliary adjustment, so that the butt joint blocks 406 uniformly distributed on the movable plate are accurately connected with the butt joint grooves 407 on the corresponding side surface of the connecting base 1, thereby realizing the stable connection of the movable support plate 5 and the connecting base 1. At the same time, the fixed support plate 2 is matched, the bearing shaft 6 is stably connected, and the protective sleeve 7 is limited on the bearing shaft 6, fully preparing for subsequent support of the silicon rod 9 and detection.

[0029] When it is necessary to replace the protective sleeve 7, the operation process is also convenient and efficient. The worker only needs to pull the two pressing plates 302 upward to separate the matching column 403 from the limiting groove 303, and then easily separate the movable support plate 5 from the connecting base 1 and the bearing column. Under the support of the connecting column 405, the worker can rotate the movable support plate 5 to remove the limiting sleeve from the bearing shaft 6 for replacement. After replacement is completed, the reverse operation steps are performed for resetting and installation. It is worth mentioning that during the replacement of the limiting sleeve, the connecting base 1 remains fixed and does not move, and at the same time, the fixed support plate 2 anchors the overall position. The movable support plate 5 is auxiliary limited by the connecting column 405, maintaining the relative stability of the position, which means that the movement of the movable support plate 5 will not affect the position adjusted when the connecting base 1 is fixed. Through this design, the replacement of the protective sleeve 7 can be realized without disassembling the structure in a large range and with great effort.

[0030] The two ends of the control sleeve 301 are fixedly connected with the ends of the two pressing plates 302 away from the support shaft 305, and the control sleeve 301 is designed in a U shape, which greatly facilitates the operation of the staff in simultaneously pulling the two pressing plates 302. The staff can easily press and lock the position of the matching column 403 through the control sleeve 301, so as to fix the position of the movable supporting plate 5 and realize the limiting of the protective sleeve 7. The staff can also make the matching column 403 separate from the limiting groove 303 through the control sleeve 301, so as to conveniently disassemble and replace the protective sleeve 7. The control sleeve 301 is made of elastic material and can tightly clamp the vertical end of the base 1, further assisting in positioning the two pressing plates 302, so as to more stably lock the position of the movable supporting plate 5 and realize the convenient replacement of the protective sleeve 7.

[0031] The horizontal section of the limiting sleeve away from the movable supporting plate 5 is provided with a chamfer. This design fully considers the operation convenience of the staff, and the staff can easily insert the hand into the chamfer, pull the control sleeve 301 upwards, make the limiting groove 303 on the pressing plate 302 separate from the matching column 403, and greatly facilitate the replacement of the protective sleeve 7. Stable columns 402 are arranged on the two sides of the limiting groove 303 away from the connecting column 405, and the two stable columns 402 are in sliding fit with the two ends of the matching column 403, so as to ensure the smooth movement of the matching column 403 in the limiting groove 303. Meanwhile, a tension spring 404 is arranged between the inner wall of the side of the matching column 403 close to the movable supporting plate 5 and the limiting groove 303, and surrounds the stable column 402. When the matching column 403 separates from the limiting groove 303, the tension spring 404 will quickly act, push the connecting column 405, and make the movable supporting plate 5 quickly separate from the bearing shaft 6 and the connecting base 1, so as to greatly improve the efficiency of the replacement of the limiting sleeve. The tension of the tension spring 404 can also improve the force of the matching column 403 pressing the limiting groove 303 to a certain extent, so as to improve the friction between the matching column 403 and the limiting groove 303, and further improve the connection stability of the limiting groove 303 and the matching column 403.

[0032] The cross section of the connecting column 405 at the connecting position with the movable supporting plate 5 is designed in a H shape, which effectively ensures the stability of the rotating connection between the connecting column 405 and the movable supporting plate 5, and at the same time, greatly reduces the position change between the movable supporting plate 5 and the connecting column 405. Through this design, the change of the position of the bearing column caused by the movement of the movable supporting plate 5 can be effectively avoided, and the probability of affecting the subsequent detection of the silicon rod 9 is reduced.

[0033] The specific embodiments of the utility model are described above. It should be understood that the utility model is not limited to the above specific embodiments, and various modifications or changes can be made by those skilled in the art within the scope of the claims, which does not affect the essential content of the utility model.
