Technical Field
[0001] The utility model relates to the technical field of semiconductor material processing equipment, in particular to an adjustable cushion block for a loading table of a high-precision grinding and polishing machine. Background Technique
[0002] In the field of semiconductor material processing, especially in the grinding and polishing process of silicon rods, the design of the loading table has an important impact on the efficiency and precision of the entire processing process. Traditional loading tables usually use fixed cushion blocks to support and position the silicon rods to be processed. This design can meet the basic requirements of silicon rod processing to a certain extent, but there are still defects, specifically manifested as follows:
[0003] (1) Limited adaptability: Fixed cushion blocks are difficult to adapt to silicon rods of different sizes and shapes. Especially in mass production, when silicon rods of different specifications need to be frequently replaced, the limitations of fixed cushion blocks will reduce the overall processing efficiency;
[0004] (2) Limited precision: Since fixed cushion blocks cannot be finely adjusted according to the specific conditions of silicon rods, inaccurate positioning may occur during the processing process, thus affecting the processing precision;
[0005] (3) Complicated operation: Each time a silicon rod of a different specification is replaced, the position and attitude of the cushion block need to be manually adjusted, which not only increases the complexity of the operation, but also prolongs the processing time and reduces the production efficiency. Content of the Utility Model

[0009] The middle part of the adjusting assembly is provided with a lifting shaft. The upper part of the lifting shaft contacts the lower surface of the cushion block. A lifting adjustment knob is sleeved outside the lifting shaft, and the two form a rotational guiding fit. The side surface of the lifting adjustment knob protrudes from the side surface of the base, so as to control the lifting of the lifting shaft through the knob, thereby adjusting the height of the cushion block;
[0010] The middle part of the fixing assembly is provided with a support column. The top of the support column contacts the lower surface of the cushion block. The bottom of the support column is connected to a fixing knob. The side surface of the fixing knob protrudes from the side surface of the base, so as to adjust the height difference between the two sides of the cushion block through the knob, thereby adjusting the inclination angle of the cushion block.
[0011] Further, the base is of a rectangular structure and is provided with a cushion block groove inside. The bottom of the cushion block groove is communicated with a group of vertical adjustment cavities. The cushion block is arranged in the cushion block groove, and the adjusting assembly and the fixing assembly are respectively arranged in the corresponding adjustment cavities.
[0012] Further, the adjusting assembly is a screw lifting mechanism, a hydraulic lifting mechanism, a pneumatic or electric adjusting mechanism.

[0016] (1) Due to the support surface design of the cushion block main body and the introduction of the adjustment mechanism, the cushion block of the present utility model can flexibly adapt to silicon rods of different sizes and shapes, thereby improving the adaptability of silicon rod grinding and polishing processing. In practical applications, by adjusting the height of the cushion block, the inclination angle of the silicon rod can be adjusted, and silicon rods within different diameter ranges can be adapted, greatly reducing the equipment adjustment time caused by the replacement of silicon rod specifications;
[0017] (2) The fine adjustment function of the present utility model enables the silicon rod to achieve more accurate positioning and stable support during the processing process, thereby reducing the processing error and improving the processing accuracy. The optimized cushion block design can improve the processing accuracy to ±0.01 mm, meeting the requirements of high-precision processing;
[0018] (3) Compared with the fixed cushion block, the adjustable cushion block of the present utility model simplifies the operation process, reduces the time and complexity of manual adjustment, and the operator can quickly adjust the cushion block, improving the production efficiency;
[0019] (4) The adjustable cushion block of the present utility model improves the processing efficiency and accuracy, reduces the rejection rate and the need for secondary processing, thereby reducing the production cost.
