[0002] Imitation silicon rods are materials for processing semiconductor silicon wafers. Before processing the silicon rods into silicon wafers, a silicon rod cutter is needed to cut the original long silicon rods into multiple short sections of rods, and then carry out subsequent rolling, squaring and other work.

However, since it is necessary to install and grind one by one, the work efficiency is very low.

[0004] In order to improve production efficiency, our company sets up corresponding grinding mechanism based on the conveying structure to improve production efficiency. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a rolling grinding auxiliary mechanism for silicon rod processing which improves production efficiency, has high clamping accuracy and high rolling grinding accuracy.

[0006] The purpose of the utility model is achieved through the following technical solutions: a rolling auxiliary mechanism for silicon rod processing, including an upper buckle plate, a lower support plate, a rolling machine, and a conveying chain plate;

[0007] A plurality of material-carrying bases are installed at intervals on the conveying chain plate, and silicon rod short sections are installed on the upper surfaces of the material-carrying bases;

[0008] A lower support plate capable of moving up and down is provided below the conveying chain plate, an upper buckle plate capable of moving up and down is provided just above the conveying chain plate, and a roller grinder is provided just above the upper buckle plate;

[0009] A plurality of buckle boxes are arranged on the lower surface of the upper buckle plate, and the buckle boxes are opposite to the loading base; a driving motor A and a cylinder A are respectively arranged on both sides of the buckle box, an arc groove is opened on the inner bottom surface of the buckle box, and a rectangular long hole A is opened at the arc groove, and the rectangular long hole A penetrates the buckle box and the upper buckle plate;

[0010] First, move the lower support plate and stick it to the lower surface of the conveyor chain plate to provide support; then move the upper buckle plate to buckle the buckle box on the loading base, and press the arc groove on the surface of the silicon rod short section; then extend the output rod of the cylinder A and press it against one end face of the silicon rod short section, and finally make the other end face of the silicon rod short section press against the output shaft end of the driving motor A, the silicon rod short section is fixed and clamped, and then the buckle box moves upward; then extend the grinding head of the roller grinder into the buckle box through the rectangular long hole A and press it against the cylindrical surface of the silicon rod short section; when the driving motor A rotates and the grinding head of the roller grinder rotates, a part of the cylindrical surface of the silicon rod short section can be grinded, and when the roller grinder drives the grinding head to move along the length direction of the rectangular long hole A, the entire cylindrical surface of the silicon rod short section can be grinded.

[0011] As a preferred technical solution of the present application, it is stipulated that the conveying direction of the conveying chain plate is from front to back:

[0012] The driving motor A and the cylinder A are respectively arranged on the right outer wall and the left outer wall of the buckle box, and the output shaft of the driving motor A extends into the buckle box after passing through the corresponding wall, and the output rod of the cylinder A extends into the buckle box after passing through the corresponding wall;

[0014] As a preferred technical solution of the present application, the spacing between adjacent buckle boxes on the upper buckle plate is smaller than the spacing between adjacent material-carrying bases on the conveying chain plate; the rotating parts at both ends of the conveying chain plate are installed on the frame through an elastic structure, so that the conveying chain plate can telescope in the conveying direction; the conveying chain plate is hinged with multiple plates, and there are at least two plates between adjacent material-carrying bases. The upper surface of the lower support plate is provided with a hydraulic telescopic pin, and the end of the hydraulic telescopic pin is provided with a pressure sensor;

[0015] When the conveyor chain transports the corresponding loading base to the bottom of the buckle box, the lower support plate moves upward and the plate without the loading base is pushed up by the hydraulic telescopic pin, which will initially align the position of the loading base and the buckle box. During this process, the two ends of the conveyor chain produce a certain movement toward the middle; then the buckle box is buckled on the loading base, and under the action of the corresponding inclined surface, the buckle box calibrates the position of the loading base. During the calibration process, the hydraulic telescopic pin retracts until the pressure sensor is in a pressure-free position.

[0016] As a preferred technical solution of the present application, a top plate is also provided above the upper buckle plate; the upper surface of the top plate is mounted on the frame via a plurality of cylinders B, a column is fixed on the lower surface of the top plate, the lower end of the column passes through the upper buckle plate, and the end through which the column passes is screwed with a limit nut; a spring B is sleeved on the column, and the two ends of the spring B are against the top plate and the upper buckle plate; a plurality of rectangular long holes B are opened on the top plate, a roller grinder is placed in the rectangular long holes B, a grinding head is installed at the lower end of the roller grinder via an output rod, the upper part of the roller grinder is fixed on a slide seat, the slide seat is adapted to be installed with the slide rail on the top plate, and the slide seat is also threadedly matched with the output shaft of the drive motor B;

[0017] When cylinder B extends, it can drive the buckle box and the roller grinder to move downward, allowing the buckle box to buckle on the loading base; when cylinder B continues to extend, the column continues to move downward relative to the upper buckle plate, allowing the roller grinder to continue to move downward, and allowing the grinding head of the roller grinder to extend into the buckle box through the rectangular long hole A to contact the silicon rod short section.

[0018] As a preferred technical solution of the present application, the lower support plate is arranged on the frame via a plurality of cylinders C.

[0019] As a preferred technical solution of the present application, both ends of the conveying chain plate are sleeved on the hexagonal roller, and the two ends of the rotating shaft of the hexagonal roller are respectively installed on ear seats, and the two ear seats are fixed on the first base plate; the first base plate is passed through a plurality of plug posts on the second base frame, and a spring A is sleeved on the plug post and the two ends of the spring A are respectively against the first base plate and the second base frame, and a fixing nut is screwed on the end of the plug post passing through the second base frame, and the second base frame is fixed on the frame.

[0020] As a preferred technical solution of the present application, a semicircular discharge groove is provided on the upper surface of the loading base, and the semicircular discharge groove is adapted to the cylindrical surface of the silicon rod short section; the arc-shaped groove is adapted to the cylindrical surface of the silicon rod short section; when the buckle box is buckled on the loading base, the silicon rod short section is initially fixed by the arc-shaped groove and the semicircular discharge groove, and then the output rod of the cylinder A extends out and pushes the silicon rod short section axially to the other direction, and finally the other end of the silicon rod short section is rested on the end of the output shaft of the driving motor A; the end of the output rod of the cylinder A has a tip, and the end of the output shaft of the driving motor A also has another tip.

[0021] It should be noted that in this solution, the two ends of the silicon rod short section mounted on the loading base are pre-polished; in this way, when the drive motor A and the cylinder A fix and clamp the silicon rod short section from both ends, the coaxiality between the drive motor A, the cylinder A and the silicon rod short section can be guaranteed (there may be deviations, but the error can be reduced after rolling).

[0022] In order to facilitate understanding, the principles and core design points of this solution are explained:

[0023] 1. Working principle;

[0024] a. Transport the silicon rod short section through the conveying chain plate and the material-carrying matrix thereon; b. Then support the conveying chain plate from below through the lower support plate, and buckle the buckle box on the material-carrying matrix through the upper buckle plate (in the buckling process, the elastically arranged structures at both ends of the conveying chain plate and the hydraulic telescopic pins on the support plate can automatically correct the position of the material-carrying matrix through the buckle box. Only accurate position can ensure the accuracy of subsequent grinding); c. Then clamp and fix the silicon rod short section through the cylinder A and the drive motor A, and then separate the buckle box from the material-carrying matrix; d. Then use the roller grinder to extend its grinding head into the buckle box through the rectangular long hole A and contact with the cylindrical surface of the silicon rod short section; e. When the drive motor When the machine A rotates, it will drive the silicon rod short section to rotate, so the roller grinder will grind a circle at a certain position of the silicon rod short section (for example, the grinding head of the roller grinder (the grinding head itself will rotate) is located at the left end of the silicon rod short section, when the drive motor A rotates, the grinding head will grind the cylindrical surface at the left end of the silicon rod short section); when the roller grinder moves along the length direction of the rectangular long hole A, it can gradually grind all the silicon rod short sections (for example, when the grinding head of the roller grinder moves from the left end to the right end of the silicon rod short section along the length direction of the rectangular long hole A, the drive motor A rotates and the grinding head rotates at the same time, so all the cylindrical surfaces of the silicon rod short section can be polished).

[0025] Second, one of the core innovations is that the position of the silicon rod short section can be corrected through the structure of the conveying chain plate and the buckle box, so that multiple silicon rod short sections can be accurately fixed and clamped at one time, so that multiple silicon rod short sections can be polished at the same time, improving production efficiency;

[0026] There are many existing grinding methods. The most common one is to clamp and fix the individual silicon rod short sections one by one, and then use a roller grinding column to gradually grind the silicon rod short sections. This work efficiency is extremely low.

[0027] In the present application, the silicon rod short section is moved by the conveying chain plate, and the position is corrected by the buckle box during the movement, and the supporting force is provided by the support plate, so that multiple silicon rod short sections on the conveying chain plate can be polished; (the difficulty is that it is difficult for the conveying structure to ensure that the loading base is aligned with the buckle box; for example, the easiest way to think of is to install the loading base on the soft conveying belt, but the soft conveying belt itself has ductility. As the working time increases, the position deviation between the loading base and the buckle box will become larger and larger, and even the buckle cannot be buckled; therefore, in the present application, the loading base is installed on the conveying chain plate, Since the conveyor chain plate itself has very weak ductility, the positional relationship between the buckle box and the material-carrying base can be guaranteed to a certain extent - although there is a deviation, it is not large. However, the conveyor chain plate is made up of multiple plates hinged together, and there is a gap at the hinge. Therefore, there is also a certain position error between the material-carrying base on the conveyor chain plate and the buckle box; finally, the hydraulic telescopic pins on the support plate will push up some plates on the conveyor chain plate, and the elastic structure at both ends of the conveyor chain plate will automatically retract the conveyor chain plate. When the buckle box is buckled with the material-carrying base, even if there is an error, the position of the net material-carrying base can be corrected, for example Figure 6 As shown, when the material-carrying base is slightly in front of the buckle box, when the buckle box is buckled on the material-carrying base, the corresponding inclined surface will cause the material-carrying base to move backwards, at which time the upwardly protruding plate on the front side of the material-carrying base will drop downwards, and the upwardly protruding plate on the rear side of the material-carrying base will rise upwards (if a soft conveyor belt is used, the buckle box and the material-carrying base may be completely misaligned and cannot be buckled);

[0028] Second, one of the core design points is: the roller grinder is installed on the top plate, the top plate and the upper buckle plate are elastically arranged to move up and down, the buckle box is installed on the upper buckle plate, and the driving motor A and the cylinder A are respectively arranged on both sides of the buckle box (the relative position between the roller grinder and the buckle box is fixed);

[0029] Specifically, when the buckle box is buckled on the material-carrying base and the position of the material-carrying base is corrected, the silicon rod short section is clamped and fixed from both ends by the driving motor A and the cylinder, and then the grinding head of the roller grinder can directly extend into the buckle box through the rectangular long hole A, and the roller grinder can directly grind the cylindrical surface of the silicon rod short section (the traditional fixing method, such as the patent CN213136070U, after each silicon rod is fixed, if the installation and fixing position is not accurate enough, the position between the silicon rod short section and the roller grinding column is not accurate enough, which affects the subsequent grinding; the silicon rod short section of this scheme is placed in the semicircular discharge groove of the material-carrying base. Although the roughness of the surface of the silicon rod short section will have a certain impact on the accuracy of subsequent clamping and fixing, the impact is very small, which ensures the fixing accuracy between the silicon rod short section and the driving motor A and the cylinder A, and the position of the buckle box and the roller grinder is relatively fixed, so the roller grinder can ensure the accuracy after roller grinding);

[0030] That is, the clamping accuracy is high and the grinding accuracy is high.

[0031] The utility model has the following advantages: the position of the silicon rod short section can be automatically adjusted, thereby facilitating subsequent batch rolling processing and improving the working efficiency of rolling; in addition, the clamping accuracy of the silicon rod short section is high when it is fixed, so that the rolling accuracy after subsequent rolling is high.

[0048] See also Figure 1 to Figure 3 , Figure 5 to Figure 7 As shown, the roller grinding auxiliary mechanism for silicon rod processing proposed in this embodiment includes an upper buckle plate 10, a lower support plate 20, a roller grinding machine 30, and a conveyor chain plate 40;

[0049] A plurality of material-carrying bases 41 are installed at intervals on the conveying chain plate 40, and silicon rod short sections are placed on the upper surfaces of the material-carrying bases 41;

[0052] During operation, first move the lower support plate 20 and attach it to the lower surface of the conveying chain plate 40 to provide support; then move the upper buckle plate 10 to allow the buckle box 11 to buckle on the loading base 41, and the arc groove 1103 is pressed on the surface of the silicon rod short section; then extend the output rod of the cylinder A1102 and abut against one end face of the silicon rod short section, and finally allow the other end face of the silicon rod short section to abut against the output shaft end of the driving motor A1101, the silicon rod short section is fixed and clamped, and then the buckle box 11 moves upward; then extend the grinding head of the roller grinder 30 into the buckle box 11 through the rectangular long hole A1104, and abut against the cylindrical surface of the silicon rod short section; when the driving motor A1101 rotates and the grinding head of the roller grinder 30 rotates, a part of the cylindrical surface of the silicon rod short section can be polished, and when the roller grinder 30 drives the grinding head to move along the length direction of the rectangular long hole A1104, the entire cylindrical surface of the silicon rod short section can be polished;

[0053] It should be noted that the conveying direction of the conveying chain plate 40 is specified to be from front to back.

[0054] See also Figure 2 , Figure 3 and Figure 7 As shown, the buckling structure of the buckle box 11 and the material-carrying base 41 and the structure for clamping and fixing the silicon rod short section are designed;

[0055] Specifically, a semicircular discharge groove 4101 is formed on the upper surface of the material-carrying base 41, and the semicircular discharge groove 4101 is adapted to the cylindrical surface of the silicon rod short section; the arc groove 1103 is adapted to the cylindrical surface of the silicon rod short section;

[0056] In addition, the drive motor A1101 and the cylinder A1102 are respectively arranged on the right outer wall and the left outer wall of the buckle box 11, and the output shaft of the drive motor A1101 passes through the corresponding wall and then extends into the buckle box 11, and the output rod of the cylinder A1102 passes through the corresponding wall and then extends into the buckle box 11; and the end of the output rod of the cylinder A1102 has a tip, and the end of the output shaft of the drive motor A1101 also has another tip;

[0057] In addition, the front and rear outer side walls of the material-carrying base 41 are inclined, forming a structure that is small at the top and large at the bottom; the front and rear inner side walls of the buckle box 11 are inclined to match the front and rear outer side walls of the material-carrying base 41; when the buckle box 11 is buckled on the material-carrying base 41, the position of the material-carrying base 41 can be calibrated;

[0058] When the buckle box 11 is buckled onto the loading base 41: the silicon rod short section is initially fixed through the arc groove 1103 and the semicircular discharge groove 4101, and then the output rod of the cylinder A1102 extends and pushes the silicon rod short section axially to the other direction, and finally the other end of the silicon rod short section is against the end of the output shaft of the driving motor A1101.

[0059] See also Figure 1and Figure 6 , a structure is designed to enable the material-carrying base 41 to move forward and backward on the conveying chain plate 20; specifically, the spacing between adjacent buckle boxes 11 on the upper buckle plate 10 is smaller than the spacing between adjacent material-carrying bases 41 on the conveying chain plate 40; in addition, the rotating parts at both ends of the conveying chain plate 40 are installed on the frame through an elastic structure, so that the conveying chain plate 40 can move telescopically in the conveying direction; and the conveying chain plate 40 is formed by hingedly connecting a plurality of plates, and at least two plates are spaced between adjacent material-carrying bases 41; and a hydraulic telescopic pin 21 is provided on the upper surface of the lower support plate 20, and a pressure sensor is provided at the end of the hydraulic telescopic pin 21;

[0060] During operation: when the conveying chain plate 40 transports the corresponding material-carrying base 41 to the bottom of the buckle box 11, the lower support plate 20 moves upward, and the plate without the material-carrying base 41 is lifted upward by the hydraulic telescopic pin 21, so that the position of the material-carrying base 41 and the buckle box 11 are initially aligned. During this process, the two ends of the conveying chain plate 40 move toward the middle to a certain extent; then the buckle box 11 is buckled on the material-carrying base 41, and the buckle box 11 calibrates the position of the material-carrying base 41 under the action of the corresponding inclined surface. During the calibration process, the hydraulic telescopic pin 21 retracts until the pressure sensor is in a pressure-free position (for example Figure 6 In the process, when the loading base is slightly in front of the buckle box, when the buckle box is buckled on the loading base, the corresponding inclined surface will make the loading base move backward. At this time, the upward protruding plate on the front side of the loading base will drop downward, and the upward protruding plate on the back side of the loading base will rise upward (if a soft conveyor belt is used, the buckle box and the loading base may be completely misaligned and cannot be buckled)).

[0061] In this embodiment, the lower support plate 20 is arranged on the frame via a plurality of cylinders C22.

[0062] (Example 2)

[0063] On the basis of Example 1, the installation of the roller grinder is also designed (it should be noted that the roller grinder itself has a very simple structure, with a motor body, an output rod extending from the lower end of the motor body, and a grinding head at the lower end of the output rod).

[0064] Specifically, see Figure 4 A top plate 50 is also arranged above the upper buckle plate 10. The upper surface of the top plate 50 is mounted on the frame via a plurality of cylinders B51. A column 52 is fixed to the lower surface of the top plate 50. The lower end of the column 52 passes through the upper buckle plate 10, and the end through which it passes is screwed with a limiting nut 53. A spring B54 is sleeved on the column 52, and both ends of the spring B54 abut against the top plate 50 and the upper buckle plate 10.

[0065] In addition, a plurality of rectangular long holes B55 are opened on the top plate 50 (the length direction of the rectangular long holes B55 is parallel to the axial direction of the silicon rod short section on the loading base 41), and a roller grinder 30 is placed in the rectangular long holes B55. A grinding head is installed at the lower end of the roller grinder 30 through an output rod. The upper part of the roller grinder 30 is fixed on a slide seat 56. The slide seat 56 is adapted to be installed with the slide rail on the top plate 50, and the slide seat 56 is also threadedly matched with the output shaft of the driving motor B.

[0066] During operation, when the cylinder B51 extends, it can drive the buckle box 11 and the roller grinder 30 to move downward, so that the buckle box 11 is buckled on the loading base 41; when the cylinder B51 continues to extend, the column 52 continues to move downward relative to the upper buckle plate 10, allowing the roller grinder 30 to continue to move downward, and allowing the grinding head of the roller grinder 30 to extend into the buckle box 11 through the rectangular long hole A1104 and contact the silicon rod short section; in addition, under the action of the driving motor B, the grinder 30 can also move along the axial direction of the silicon rod short section, so as to facilitate the grinding of all cylindrical surfaces of the silicon rod short section.

[0067] In this embodiment, Figure 5 As shown, both ends of the conveying chain plate 40 are sleeved on the hexagonal roller 42, and both ends of the rotating shaft of the hexagonal roller 42 are respectively mounted on the ear seats 43, and the two ear seats 43 are fixed on the first bottom plate 44; the first bottom plate 44 is penetrated by a plurality of plug posts 45 on the second bottom plate frame 46, and the plug posts 45 are sleeved with springs A47, and the two ends of the spring A47 are respectively against the first bottom plate 44 and the second bottom plate frame 46, and the end of the plug posts 45 passing through the second bottom plate frame 46 is screwed with fixing nuts, and the second bottom plate frame 46 is fixed to the frame.
