Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod processing equipment, and particularly relates to a silicon rod crystal line adjusting device. Background Art

[0002] The information provided in this part is only background information related to the present disclosure, and it does not necessarily constitute prior art.

[0003] Silicon wafers used for manufacturing semiconductor electronic components such as integrated circuits are mainly manufactured by slicing single crystal silicon rods pulled by the Czochralski method. After the crystal pulling is completed, the shape of the single crystal silicon rod is nearly cylindrical, and multiple detection crystal lines are evenly distributed at nearly 90°. The existence of the crystal lines indicates that the crystal is growing in the form of a single crystal inside. When the crystal lines disappear, it indicates that the crystal plane of the crystal has deflected, resulting in crystals in different directions. The disconnection of the crystal lines can be used to characterize the transformation of the crystal rod from single crystal growth mode to polycrystal growth mode. Therefore, before the single crystal silicon rod is cut into segments, it is necessary to detect the crystal lines of the single crystal silicon rod after the crystal pulling is completed, and then rotate the single crystal silicon rod to avoid the cutting tool head facing the crystal lines.

[0004] Currently, the method for adjusting the crystal lines is mostly to manually observe the position of the crystal lines and then manually adjust the position of the crystal lines, with low efficiency.

[0069] The specific embodiments of the present invention will be elaborated in detail below in conjunction with the silicon rod crystal line adjusting device of the first aspect of the present invention.

[0070] It should be noted that the silicon rod crystal line adjusting device of the first aspect of the present invention is only a preferred embodiment of the present invention. The silicon rod crystal line adjusting device of the present invention can either adopt the silicon rod crystal line adjusting device of the first aspect of the present invention or other structures. For the convenience of elaboration, the following will be elaborated in detail through the silicon rod crystal line adjusting device of the first aspect of the present invention.

[0071] Combined Figure 1 and Figure 2 As shown, this embodiment discloses a silicon rod crystal line adjusting device, which includes a bracket 9, a clamping assembly 1, and a clamping assembly driving mechanism. There are at least two clamping assemblies 1. The top of the clamping assembly 1 has a clamping position 13 for supporting and clamping a single crystal silicon rod. Each clamping assembly 1 is arranged at intervals on the bracket 9, and the clamping positions 13 of each clamping assembly 1 are located on the same straight line. The clamping assembly driving mechanism is connected to each clamping assembly 1 and is adapted to drive each clamping assembly 1 to rotate synchronously.

[0072] The above-mentioned silicon rod crystal line adjusting device is different from the existing device for clamping the end of a single crystal silicon rod. In this embodiment, at least two clamping assemblies 1 arranged at intervals are used to support and clamp the single crystal silicon rod, so as to realize the clamping of the single crystal silicon rod after crystal pulling. The clamping assembly driving mechanism is used to control each clamping assembly 1 to rotate synchronously, thereby driving each position of the single crystal silicon rod to rotate synchronously, realizing the automatic and precise adjustment of the crystal line position of the single crystal silicon rod, and improving the crystal line adjustment efficiency.

[0073] Each clamping component 1 in the above silicon rod crystal line adjusting device is arranged at intervals on the bracket 9. Therefore, it can be adapted to the AGV cart. The single crystal silicon rod after crystal pulling can be automatically placed at the clamping position 13 of each clamping component 1 by the AGV cart. The specific process is as follows: The single crystal silicon rod after crystal pulling is transported to the AGV cart. The AGV cart moves to the feeding area of the silicon rod crystal line adjusting device, so that the fork on the AGV cart is staggered with each clamping component 1. The fork on the AGV cart rises (the rising height of the AGV cart is higher than the topmost end of the clamping component 1), and the fork is pushed forward by the pushing mechanism on the AGV cart. Then the AGV cart descends. Because the fork on the AGV cart is staggered with each clamping component 1, the single crystal silicon rod on it will be supported by the clamping position 13 of each clamping component 1 when the fork on the AGV cart descends. Finally, the AGV cart drives away from the feeding area of the silicon rod crystal line adjusting device, completing the automatic feeding of the single crystal silicon rod.

[0074] In some embodiments, the clamping component 1 includes a rotating roller bracket 14, a first rotating roller 11, and a second rotating roller 12. The rotating roller bracket 14 is connected to the side wall of the bracket 9. The first rotating roller 11 is rotatably arranged on the rotating roller bracket 14. The second rotating roller 12 is rotatably arranged on the rotating roller bracket 14. There is a spacing between the upper part of the second rotating roller 12 and the upper part of the first rotating roller 11 to form the clamping position 13.

[0075] In this embodiment, the second rotating roller 12 rotates in the same direction as the first rotating roller 11, thereby providing a rotating force for the single crystal silicon rod to rotate in one direction, enabling the clamped single crystal silicon rod to rotate and realizing the adjustment of the crystal line of the single crystal silicon rod.

[0076] In some embodiments, the clamping component driving mechanism includes a driving motor 2 and a linkage component. The linkage component is connected to the output shaft end of the driving motor 2, and the linkage component is respectively connected to each clamping component 1.

[0077] The linkage component includes a first linkage component 3, a first driving shaft 4, and a first driving shaft connection component. There are at least two first linkage components 3. Each first linkage component 3 is respectively connected to a clamping component 1. The first driving shaft 4 passes through each rotating roller bracket 14 and is respectively connected to each first linkage component 3. The first driving shaft 4 is adapted to drive each first linkage component 3 to run synchronously. The first driving shaft connection component is connected between the first driving shaft 4 and the output shaft of the driving motor 2. In this embodiment, when the first driving shaft 4 rotates, it can drive each first linkage component 3 to rotate, thereby driving multiple rows of clamping components 1 to rotate synchronously, avoiding the problem of increasing the equipment manufacturing cost due to each clamping component 1 being driven by a separate driving motor 2, and avoiding the problem that the response times of the driving motors 2 cannot be synchronized, resulting in the asynchronous operation of each clamping component 1.

[0078] More specifically, the first linkage assembly 3 includes a first rotating roller drive sprocket 32, a second rotating roller drive sprocket 33, a first intermediate sprocket 34, a first drive shaft driven sprocket 35, and a first chain 31. The first rotating roller drive sprocket 32 is coaxially connected to the first rotating roller 11. The second rotating roller drive sprocket 33 is coaxially connected to the second rotating roller 12. At least one first intermediate sprocket 34 is provided, and the first intermediate sprocket 34 is rotatably provided on the rotating roller bracket 14. The first drive shaft driven sprocket 35 is coaxially provided on the first drive shaft 4. The first chain 31 is sleeved on the first drive shaft driven sprocket 35, the first rotating roller drive sprocket 32, the second rotating roller drive sprocket 33, and the first intermediate sprocket 34, so that the first drive shaft 4 is linked with the first drive shaft driven sprocket 35 and the first rotating roller drive sprocket 32 respectively. In this embodiment, when the first drive shaft 4 rotates, it can drive the first chain 31 to rotate, and then drive the first rotating roller drive sprocket 32 and the second rotating roller drive sprocket 33 to rotate synchronously.

[0079] When the first chain 31 is arranged, if the first chain 31 directly bypasses from above the first rotating roller drive sprocket 32 and the second rotating roller drive sprocket 33, it will occupy the space of the clamping position 13, resulting in the single crystal silicon rod being unable to pass through this position. To solve this technical problem, in some embodiments, a first intermediate sprocket 34 is provided at the lower position between the first rotating roller drive sprocket 32 and the second rotating roller drive sprocket 33. After the first chain 31 bypasses from above the first rotating roller drive sprocket 32, it bypasses from below this first intermediate sprocket 34, and then bypasses from above the second rotating roller drive sprocket 33, so that the first chain 31 does not occupy the space of the clamping position 13 and there is no interference between the first chain 31 and the clamping position 13.

[0080] In some embodiments, the first drive shaft connection assembly includes an extension bracket 8, a second drive shaft 6, a second linkage assembly 5, and a third linkage assembly 7. Two extension brackets 8 are provided, and the two extension brackets 8 are provided on the side walls of the bracket 9. Each extension bracket 8 corresponds to a rotating roller bracket 14 respectively, and the extension bracket 8 and the rotating roller bracket 14 are located on both sides of the bracket 9. The two ends of the second drive shaft 6 are rotatably provided on the two extension brackets 8 respectively. The second linkage assembly 5 is connected between the first drive shaft 4 and the second drive shaft 6. The third linkage assembly 7 is connected between the second drive shaft 6 and the output shaft of the drive motor 2.

[0081] More specifically, the second linkage assembly 5 includes a first drive shaft driving sprocket 52, a second drive shaft driven sprocket 53, a second idler sprocket 54, and a second chain 51. The first drive shaft driving sprocket 52 is coaxially connected to the first drive shaft 4. The second drive shaft driven sprocket 53 is coaxially connected to the second drive shaft 6. At least one second idler sprocket 54 is provided, and the second idler sprocket 54 is rotatably arranged on the extension bracket 8. The second chain 51 is sleeved on the first drive shaft driving sprocket 52, the second drive shaft driven sprocket 53, and the second idler sprocket 54, so that the first drive shaft 4 and the second drive shaft 6 are linked.

[0082] The third linkage assembly 7 includes a drive motor driving sprocket 72, a second drive shaft driving sprocket 73, and a third chain 71. The drive motor driving sprocket 72 is coaxially connected to the output shaft of the drive motor 2. The second drive shaft driving sprocket 73 is coaxially connected to the second drive shaft 6. The third chain 71 is sleeved between the drive motor driving sprocket 72 and the second drive shaft driving sprocket 73.

[0083] In some embodiments, a receiving cavity adapted to receive the first linkage assembly 3 is provided on the rotating roller bracket 14, and the receiving cavity is sealed by an outer cover 10. In this embodiment, by providing an installation space for the first linkage assembly 3 through the receiving cavity and using the outer cover 10 to block the receiving cavity, the first linkage assembly 3 in the receiving cavity can be dust-proof and protected, and the service life of the first linkage assembly 3 is extended.

[0084] The specific working process of the above silicon rod crystal wire adjusting device is as follows:

[0085] Place the single crystal silicon rod after crystal pulling on the clamping position 13 of the clamping assembly 1. The method of placing the clamping assembly 1 includes manual placement or automatic conveyance through a conveying system.

[0086] Perform crystal wire detection on the single crystal silicon rod placed on the clamping position 13.

[0087] When it is necessary to adjust the crystal line of the single-crystal silicon rod clamped at the clamping position 13, the control drives the motor 2 to start. The drive motor 2 drives the drive motor driving sprocket 72 to rotate. The drive motor driving sprocket 72 drives the second drive shaft driving sprocket 73 to rotate through the third chain 71, and then drives the second drive shaft 6 to rotate. When the second drive shaft 6 rotates, it drives the second drive shaft driven sprocket 53 to rotate. The second drive shaft driven sprocket 53 drives the first drive shaft driving sprocket 52 to rotate through the second chain 51, and then drives the first drive shaft 4 to rotate. Since the first drive shaft 4 is coaxially connected to the first drive shaft driven sprockets 35 of each first linkage assembly 3 respectively, the first drive shaft driven sprockets 35 of each first linkage assembly 3 rotate synchronously, and drive the first rotating roller driving sprockets 32 and the second rotating roller driving sprockets 33 of each first linkage assembly 3 to rotate synchronously, thereby driving the first rotating roller 11 and the second rotating roller 12 to rotate synchronously, driving the single-crystal silicon rod clamped at the clamping position 13 to rotate, and realizing the adjustment of the crystal line of the single-crystal silicon rod.

[0088] And when adjusting the crystal line of the single-crystal silicon rod, the precise adjustment of the crystal line position of the single-crystal silicon rod can be realized by controlling the operation process of the drive motor 2. When there is a deviation between the crystal line position of the exposed single-crystal silicon rod and the crystal line position to be detected, direct forward and reverse adjustment can be carried out through the drive motor 2.

[0089] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
