Technical Field

[0001] This utility model relates to the technical field of semiconductor manufacturing, and in particular to an automatic alignment device for crystal rod end caps. Background Technology

[0002] Currently, in semiconductor wafer substrate fabrication processes, end cap assembly is a critical step before dicing single-crystal silicon rods or compound semiconductor rods, and its quality directly affects the geometric accuracy and crystal structure integrity of the wafer. The industry currently relies heavily on manual operation for end cap assembly: operators must manually adjust the end cap to achieve spatial matching with the rod end face, requiring extremely high coaxiality accuracy and controllable axial pressure. This process is highly dependent on the operator's experience and skills. In manual operation, the limitations of visual calibration can easily lead to axial angle deviations, causing mechanical damage to the rod surface during assembly, thus affecting the yield of subsequent wafer dicing.

[0036] like Figures 1 to 6 As shown, a preferred embodiment of the present invention provides an automatic alignment device for crystal rod end caps, comprising:

[0037] The transfer assembly 10 includes a transfer disk 11 and a transfer drive 12. The transfer drive 12 is connected to the transfer disk 11 for rotational transmission. The transfer disk 11 is provided with a receiving groove 13 for placing end caps and crystal rods 80.

[0038] The feeding mechanism 20 includes feeding grippers 21 for gripping the crystal rod 80;

[0039] The feeding mechanism 30 includes feeding grippers 31 for gripping the crystal rod 80;

[0040] The lower end cap assembly mechanism 40 includes a first base 41 and a first push drive 44. The first push drive 44 is connected to the first base 41. The first base 41 is provided with a first through hole 42 and a lower end cap feeding area 43. The first through hole 42 is located above the corresponding receiving groove 13, and the lower end cap feeding area 43 is located between the first through hole 42 and the first push drive 44.

[0041] The upper cover assembly mechanism 60 includes a second base 61 and a second push drive 64. The second push drive 64 is connected to the second base 61. The second base 61 is provided with a second through hole 62 and an upper cover feeding area 63. The second through hole 62 is located above the corresponding accommodating groove 13 and is higher than the first through hole 42. The upper cover feeding area 63 is located between the second through hole 62 and the second push drive 64.

[0042] This utility model discloses an automatic crystal rod end cap alignment device. A transfer tray 11 has a receiving groove 13 for placing end caps and crystal rods 80. A transfer drive 12 drives the transfer tray 11 to rotate. A loading mechanism 20, a unloading mechanism 30, a lower end cap assembly mechanism 40, and an upper end cap assembly mechanism 60 are located around the transfer tray 11. A lower end cap 81 is placed on the lower end cap assembly mechanism 40. A first push drive 44 pushes the lower end cap 81 to slide along a first base 41. The lower end cap 81 falls into the receiving groove 13 through a first through hole 42, with the opening of the lower end cap 81 facing upwards. The transfer tray 11 drives the lower end cap 81 to rotate to the corresponding position below the loading mechanism 20. The loading gripper 21 clamps the crystal rod 80 and inserts one end into the lower end cap 81 of the transfer tray 11. The transfer tray 11 continues to rotate... Below the upper end cap assembly mechanism 60, an upper end cap 82 is placed on the upper end cap assembly mechanism 60. The upper end cap 82 is pushed to slide along the second base 61 by the second push drive 64. The opening of the upper end cap 82 faces downward. The upper end cap 82 falls through the second through hole 62 and covers the upper end of the crystal rod 80. The transfer tray 11 continues to rotate to the corresponding lower part of the unloading mechanism 30. The unloading claw 31 picks up the crystal rod 80 with the end cap assembled and moves it away from the receiving groove 13, thereby realizing the automated assembly of the end cap of the crystal rod 80 and improving the assembly efficiency of the end cap. At the same time, since the feeding and assembly of the end cap and the crystal rod 80 are both realized through the mechanical transmission structure, the alignment accuracy of the end cap and the crystal rod 80 is improved, and the crystal rod 80 is not scratched during the assembly of the end cap and the crystal rod 80, thus improving the yield.

[0043] As one embodiment, such as Figure 2 As shown, the material transfer drive 12 is a motor, and the drive end of the motor is connected to the axis of the material transfer disk 11, driving the material transfer disk 11 to rotate.

[0044] As one embodiment, such as Figures 3 to 4 As shown, the first push drive 44 and the second push drive 64 are cylinders.

[0045] Furthermore, such as Figure 1 As shown, the feeding mechanism 20 and the unloading mechanism 30 are arranged opposite to each other, and the lower end cap assembly mechanism 40 and the upper end cap assembly mechanism 60 are arranged opposite to each other. The unloading mechanism 30, the lower end cap assembly mechanism 40, the feeding mechanism 20 and the upper end cap assembly mechanism 60 are arranged at intervals along the circumference of the transfer tray 11, so that the receiving groove 13 in the transfer tray 11 passes through the lower end cap assembly mechanism 40, the feeding mechanism 20, the upper end cap assembly mechanism 60 and the unloading mechanism 30 in sequence, thereby completing the end cap assembly at both ends of the crystal ingot 80, optimizing the end cap assembly process and improving the end cap assembly efficiency.

[0046] Furthermore, such as Figures 1 to 2As shown, multiple receiving slots 13 are provided, and the multiple receiving slots 13 are arranged at intervals along the circumference of the transfer tray 11. The multiple receiving slots 13 can sequentially pass through the lower end cover assembly mechanism 40, the feeding mechanism 20, the upper end cover assembly mechanism 60, and the unloading mechanism 30 to assemble the end cover and the crystal rod 80, thereby improving the assembly efficiency of the end cover.

[0047] As one embodiment, such as Figures 1 to 2 As shown, four receiving slots 13 are equally spaced along the circumference of the transfer tray 11. The unloading mechanism 30, the lower end cap assembly mechanism 40, the loading mechanism 20, and the upper end cap assembly mechanism 60 are also equally spaced along the circumference of the transfer tray 11, and each corresponds to a receiving slot 13, further improving the assembly efficiency of the end cap.

[0048] Furthermore, such as Figure 3 As shown, the lower end cap assembly mechanism 40 also includes a lower end cap storage rack 45. The lower end cap storage rack 45 includes a first support rod 46, a first limiting plate 47, and a first guide tube 49. One end of the first support rod 46 is connected to the first base 41, and the other end is connected to the first limiting plate 47. The first limiting plate 47 and the first base 41 define a lower end cap loading area 43. The first limiting plate 47 has a lower end cap through hole 48. The first guide tube 49 is connected to the side of the first limiting plate 47 opposite to the lower end cap loading area 43 to form a lower end cap storage area 50. The lower end cap loading area 43 communicates with the lower end cap storage area 50 through the lower end cap through hole 48. The lower end cap storage rack 45 is used to store the lower end cap 81. The lower end cap 81 has the same structure as the upper end cap 82, except that the opening orientation is different when the lower end cap 81 and the upper end cap 82 are placed. The opening orientation of the lower end cap 81 is upward. One end of the first support rod 46 is connected to the first base 41 for fixation, and the other end is connected to the first limiting plate 47. The first support rod 46 supports the first limiting plate 47. The first limiting plate 47 and the first base 41 form a lower end cover feeding area 43. The height between the first limiting plate 47 and the first base 41 is less than the height of the two lower end covers 81. Therefore, when the first push drive 44 pushes, only the bottommost lower end cover 81 moves toward the first through hole 42. The first limiting plate 47 is provided with a lower end cover through hole 48. The second lower end cover 81 is in the lower end cover through hole 48 and is restricted by the first limiting plate 47. When the bottommost lower end cover 81 is removed, the second lower end cover 81 falls down to prepare for the next lower end cover 81 feeding, thereby realizing the automatic feeding of the lower end cover 81. The first guide tube 49 is connected to the side of the first limiting plate 47 behind the lower end cover feeding area 43 to form the lower end cover storage area 50. The lower end covers 81 are stacked sequentially in the lower end cover storage area 50 along the height direction of the first guide tube 49.

[0049] As one embodiment, such as Figure 3As shown, the first guide tube 49 is a tube body, and a lower end cover storage area 50 is formed inside the tube body. The lower end cover 81 is stacked and stored in the lower end cover storage area 50.

[0050] As one embodiment, such as Figure 3 As shown, multiple first guide tubes 49 are provided, and the multiple first guide tubes 49 define a lower end cover storage area 50. The lower end cover 81 is stacked and placed in the lower end cover storage area 50.

[0051] As one embodiment, such as Figure 3 As shown, the first limiting plate 47 is square, and four first guide tubes 49 are provided. One first guide tube 49 is connected to each of the four corners of the first limiting plate 47, and the four first guide tubes 49 define the lower end cover storage area 50.

[0052] Furthermore, such as Figure 4 As shown, the upper cover assembly mechanism 60 also includes an upper cover storage rack 65. The upper cover storage rack 65 includes a second support rod 66, a second limiting plate 67, and a second guide tube 69. One end of the second support rod 66 is connected to the second base 61, and the other end is connected to the second limiting plate 67. The second limiting plate 67 and the second base 61 define an upper cover loading area 63. The second limiting plate 67 has an upper cover through hole 68. The second guide tube 69 is connected to the side of the second limiting plate 67 opposite to the upper cover loading area 63 to form an upper cover storage area 70. The upper cover loading area 63 communicates with the upper cover storage area 70 through the upper cover through hole 68. The upper cover storage rack 65 is used to store the upper cover 82. The lower cover 81 has the same structure as the upper cover 82. The opening of the upper cover 82 faces downward. One end of the second support rod 66 is connected to the second base 61 for fixation, and the other end is connected to the second limiting plate 67. The second support rod 66 supports the second limiting plate 67. The upper end cover feeding area 63 is formed between the second limiting plate 67 and the second base 61. The height between the second limiting plate 67 and the second base 61 is less than the height of the two upper end covers 82. Therefore, when the second push drive 64 pushes, only the bottommost upper end cover 82 moves toward the second through hole 62. The second limiting plate 67 is provided with an upper end cover through hole 68. The second upper end cover 82 is in the upper end cover through hole 68 and under the restriction of the second limiting plate 67, when the bottommost upper end cover 82 is removed, the second upper end cover 82 falls down to prepare for the next upper end cover 82 feeding, thereby realizing the automatic feeding of the upper end cover 82. The second guide tube 69 is connected to the side of the upper end cover feeding area 63 behind the second limiting plate 67 to form the upper end cover storage area 70. The upper end cover 82 is stacked in the upper end cover storage area 70 along the height direction of the second guide tube 69.

[0053] As one embodiment, such as Figure 4As shown, the second guide tube 69 is a tube body, and an upper end cover storage area 70 is formed inside the tube body. The upper end cover 82 is stacked and stored in the upper end cover storage area 70.

[0054] As one embodiment, such as Figure 4 As shown, multiple second guide tubes 69 are provided, and the multiple second guide tubes 69 define and form an upper cover storage area 70. The upper cover 82 is stacked and placed in the upper cover storage area 70.

[0055] As one embodiment, such as Figure 4 As shown, the second limiting plate 67 is square, and four second guide tubes 69 are provided. One second guide tube 69 is connected to each of the four corners of the second limiting plate 67, and the four second guide tubes 69 define the upper end cover storage area 70.

[0056] Furthermore, such as Figure 4 As shown, the upper cover assembly mechanism 60 also includes a pressure plate telescopic drive 71 and a pressure plate 72. The pressure plate telescopic drive 71 is connected to the second limiting plate 67, and the telescopic end of the pressure plate telescopic drive 71 is connected to the pressure plate 72. The pressure plate 72 is located above the corresponding second through hole 62, and the diameter of the pressure plate 72 is smaller than the diameter of the second through hole 62. The pressure plate telescopic drive 71 is fixed to the second limiting plate 67. After the upper cover 82 is pushed out from the upper cover loading area 63 by the second push drive 64, the upper cover 82 moves to the corresponding lower position of the pressure plate 72. The upper cover 82 falls through the second through hole 62 and covers the upper end of the crystal rod 80. The pressure plate telescopic drive 71 drives the pressure plate 72 to press the upper cover 82 downward through the second through hole 62, thereby improving the assembly yield of the upper cover 82 and the crystal rod 80. After the pressure plate 72 presses the upper cover 82, the pressure plate telescopic drive 71 drives the pressure plate 72 to move upward and reset.

[0057] As one embodiment, such as Figure 4 As shown, the pressure plate extension and retraction drive 71 is a cylinder.

[0058] Furthermore, such as Figure 5As shown, the feeding mechanism 20 also includes a feeding slide rail 22 and a feeding storage box 23. One end of the feeding slide rail 22 extends above the receiving groove 13. The feeding gripper 21 is slidably connected to the feeding slide rail 22. The feeding storage box 23 is located below the corresponding feeding slide rail 22. The feeding storage box 23 is provided with a feeding storage groove 24. The loading and storage box 23 is used to place the crystal ingot 80 to be assembled. The loading and storage box 23 is located below the loading slide rail 22. The loading gripper 21 moves along the loading slide rail 22 to the corresponding position above the loading and storage box 23. The loading gripper 21 descends and clamps the crystal ingot 80, causing the crystal ingot 80 to rise away from the loading and storage box 23. The crystal ingot 80 is then moved along the loading slide rail 22 to the corresponding position above the receiving groove 13. The lower end of the crystal ingot 80 is inserted into the lower end cover 81 of the receiving groove 13, thereby realizing the automatic loading of the crystal ingot 80 and the automatic assembly of the lower end cover 81.

[0059] As one embodiment, such as Figure 5 As shown, the material storage box 23 is provided with multiple material storage slots 24. Each material storage slot 24 can vertically place a crystal rod 80 so that the direction of the crystal rod 80 is consistent with the direction in which the crystal rod 80 is placed in the receiving slot 13, thereby improving assembly efficiency and simplifying the assembly process.

[0060] Furthermore, such as Figure 5 As shown, the feeding mechanism 20 also includes a feeding adjustment slide rail 25. The extension direction of the feeding adjustment slide rail 25 is perpendicular to the extension direction of the feeding slide rail 22. The feeding storage box 23 is slidably connected to the feeding adjustment slide rail 25. By sliding the feeding storage box 23 on the feeding adjustment slide rail 25, the feeding storage box 23 is positioned below the corresponding feeding claw 21, which improves the accuracy of the positional correspondence between the feeding claw 21 and the feeding storage box 23, and facilitates the feeding claw 21 to grip the crystal rod 80.

[0061] As one embodiment, such as Figure 5 As shown, the feeding storage box 23 is provided with multiple rows of feeding storage slots 24 spaced apart along the extension direction of the feeding adjustment slide rail 25, so as to increase the storage capacity of the feeding storage box 23 for the crystal rod 80.

[0062] Furthermore, such as Figure 6As shown, the unloading mechanism 30 also includes an unloading slide rail 32 and an unloading storage box 33. One end of the unloading slide rail 32 extends above the receiving groove 13. The unloading gripper 31 is slidably connected to the unloading slide rail 32. The unloading storage box 33 is located below the unloading slide rail 32 and has an unloading storage slot 34. The unloading storage box 33 is used to place the crystal ingot 80 with assembled end caps. The unloading storage box 33 is located below the unloading slide rail 32. The unloading gripper 31 moves along the unloading slide rail 32 to the corresponding position above the receiving groove 13. The unloading gripper 31 descends and clamps the crystal ingot 80 with the assembled end caps, causing the crystal ingot 80 to rise and move away from the receiving groove 13. The crystal ingot 80 is then moved along the loading slide rail 22 to the corresponding position above the unloading storage slot 34, and the lower end of the crystal ingot 80 is inserted into the unloading storage slot 34, thereby realizing the automatic unloading of the crystal ingot 80.

[0063] As one embodiment, such as Figure 6 As shown, the material storage box 33 is provided with multiple material storage slots 34. Each material storage slot 34 can vertically place a crystal rod 80 so that the direction of the crystal rod 80 is consistent with the direction in which the crystal rod 80 is placed in the receiving slot 13, thereby improving the material feeding efficiency.

[0064] Furthermore, such as Figure 6 As shown, the feeding mechanism 30 also includes a feeding adjustment slide rail 35, the extension direction of which is perpendicular to the extension direction of the feeding slide rail 32. The feeding storage box 33 is slidably connected to the feeding adjustment slide rail 35. By sliding the feeding storage box 33 on the feeding adjustment slide rail 35, the feeding storage box 33 is positioned below the feeding gripper 31, improving the accuracy of the positional correspondence between the feeding gripper 31 and the feeding storage box 33, and facilitating the gripper 31 in picking up the crystal ingot 80.

[0065] As one embodiment, such as Figure 6 As shown, the material storage box 33 is provided with multiple rows of material storage slots 34 spaced apart along the extension direction of the material adjustment slide rail 35, so as to increase the storage capacity of the material storage box 33 for the crystal rod 80.

[0066] As one embodiment, such as Figure 5 As shown, the feeding slide rail 22 includes a feeding bracket and a feeding linear transmission mechanism. The feeding linear transmission mechanism is connected to the feeding bracket, which supports the feeding linear transmission mechanism. The feeding linear transmission mechanism includes a motor, a coupling, a lead screw, and a slider. The motor output shaft is connected to the lead screw via the coupling. The lead screw is rotatably connected to the feeding bracket for positioning. The slider is threadedly connected to the lead screw, and the rotation of the lead screw drives the slider to rotate. The feeding gripper 21 is connected to the slider. The unloading slide rail 32, the feeding adjustment slide rail 25, and the unloading adjustment slide rail 35 have the same structure as the feeding slide rail 22. The unloading gripper 31 is connected to the slider of the unloading slide rail 32.

[0067] As one embodiment, such as Figure 5 As shown, the loading gripper 21 includes a lifting cylinder, clamping plates, and a holding cylinder. One end of the lifting cylinder is connected to the slider, and the holding cylinder is connected to the drive end of the lifting cylinder. The holding cylinder is a double-rod cylinder that can extend and retract relative to each other on both sides. Clamping plates are respectively connected to the drive ends on opposite sides of the holding cylinder. By extending and retracting the two drive ends of the holding cylinder, the two clamping plates can be moved closer or further apart, thereby achieving the clamping and unloading of the crystal ingot 80. The loading gripper 21 has the same structure as the unloading gripper 31.

[0068] In summary, this utility model embodiment provides an automatic alignment device for crystal rod end caps. The transfer tray 11 has a receiving groove 13 for placing end caps and crystal rods 80. The transfer drive 12 drives the transfer tray 11 to rotate. The loading mechanism 20, unloading mechanism 30, lower end cap assembly mechanism 40, and upper end cap assembly mechanism 60 are located around the transfer tray 11. A lower end cap 81 is placed on the lower end cap assembly mechanism 40. The lower end cap 81 is pushed along the first base 41 by the first push drive 44, and falls into the receiving groove 13 through the first through hole 42. The opening of the lower end cap 81 faces upwards. The transfer tray 11 drives the lower end cap 81 to rotate to the corresponding position below the loading mechanism 20. The loading gripper 21 clamps the crystal rod 80 and inserts one end of it into the lower end cap 81 in the transfer tray 11. The transfer tray 11... The mechanism continues to rotate to the corresponding position below the upper end cap assembly mechanism 60, where an upper end cap 82 is placed. The upper end cap 82 is pushed to slide along the second base 61 by the second push drive 64. The opening of the upper end cap 82 faces downward. The upper end cap 82 falls through the second through hole 62 and covers the upper end of the crystal rod 80. The transfer tray 11 continues to rotate to the corresponding position below the unloading mechanism 30. The unloading claw 31 picks up the crystal rod 80 with the end cap assembly completed and moves it away from the receiving groove 13, thereby realizing the automated assembly of the crystal rod 80 end cap and improving the assembly efficiency of the end cap. At the same time, since the feeding and assembly of the end cap and the crystal rod 80 are both realized through a mechanical transmission structure, the alignment accuracy of the end cap and the crystal rod 80 is improved, and the crystal rod 80 is prevented from being scratched during the assembly of the end cap and the crystal rod 80, thus improving the yield.

[0069] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
