Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon workpiece processing technology, specifically to a silicon rod grinding and chamfering mechanism. Background Technology
[0002] With the expansion of applications such as photovoltaics, the market demand for half-rod silicon wafers is gradually emerging. Half-rods are usually obtained by cutting finished square rods along their length along the centerline (i.e., the center-splitting process). The processing flow includes: half-splitting, which longitudinally cuts the square rod or finished square rod into two half-rods; and half-rod grinding, which performs secondary grinding on the surface of the center-split half-rod to meet the accuracy requirements of subsequent multi-wire cutting.
[0003] The existing semi-start technology for square silicon rods has the following bottlenecks: insufficient process coordination, mismatch between the half-slitting operation and the blanking process, resulting in equipment idling and waiting; large fluctuations in the grinding accuracy of the half rod (such as flatness deviation > 0.05mm), affecting the yield of silicon wafers; and high overall cost, with multiple equipment configurations leading to large footprint, increased energy consumption and maintenance costs.
[0004] Therefore, the industry urgently needs to develop an integrated processing solution to achieve continuous and coordinated half-section and half-bar grinding processes. In particular, it is necessary to solve core problems such as low material cutting efficiency after half-section and insufficient surface treatment precision of half-bars, so as to improve the economy and product consistency of half-bar processing.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] like Figure 1 As shown, this embodiment includes a base 10, a left slide rail 11 and a right slide rail 12 disposed on both sides of the base 10, and a grinding assembly disposed on the left slide rail 11 and the right slide rail 12 and capable of making left and right linear movements on the left slide rail 11 and the right slide rail 12; thus, the grinding assembly can make left and right linear movements through the left slide rail 11 and the right slide rail 12; in this embodiment, the left slide rail 11 and the right slide rail 12 are both electric slide rails.
[0024] On the base 10, between the left slide rail 11 and the right slide rail 12, there are parallel left tool setting assembly 13 and right tool setting assembly 14; in this embodiment, the left tool setting assembly 13 and right tool setting assembly 14 are tool setting devices that can be purchased on the market; the left tool setting assembly 13 and right tool setting assembly 14 are arranged in parallel in the middle of the base 10; thereby facilitating the grinding assembly to perform the tool setting process.
[0025] The left tool setting assembly 13 and the right tool setting assembly 14 are provided with parallel left grinding stations 30 and right grinding stations 31 on the base 10. Both the left grinding station 30 and the right grinding station 31 include a silicon rod support 32, telescopic cylinders 33 on both sides of the silicon rod support 32, and clamping plates 34 fixedly connected to the output shaft of the telescopic cylinders 33. Thus, the silicon rod to be processed is placed on the silicon rod support 32, and then the operation of the telescopic cylinders 33 causes the clamping plates 34 to clamp the silicon rod on the silicon rod support 32, which facilitates the grinding process of the grinding assembly.
[0026] In this embodiment, two silicon rods to be processed can be placed on both the left grinding station 30 and the right grinding station 31, thus enabling the simultaneous processing of four silicon rods. This solves the technical problems of equipment idling and waiting, high overall costs, and large footprint, energy consumption, and increased maintenance costs caused by multiple equipment configurations.
[0027] The grinding assembly includes a grinding fixing frame 15. In this embodiment, the grinding fixing frame 15 is slidably connected to the left slide rail 11 and the right slide rail 12, so that the grinding fixing frame 15 can make left and right linear movements on the left slide rail 11 and the right slide rail 12.
[0028] A left grinding head 16 and a right grinding head 17 are arranged parallel to each other at one end of the grinding and chamfering frame 15, and a left chamfering head 18 and a right chamfering head 19 are arranged parallel to each other at the other end of the grinding and chamfering frame 15. In this embodiment, the left grinding head 16 and the right grinding head 17 are both connected to the grinding and chamfering frame 15 via a lifting slide rail 20; the left chamfering head 18 and the right chamfering head 19 are both connected to the grinding and chamfering frame 15 via a rotary cylinder 21. Thus, the left chamfering head 18 and the right chamfering head 19 can rotate 180° in the top view plane via the rotary cylinder 21 to grind the chamfers on both sides.
[0029] In addition, the centers of the left chamfering grinding head 18, the left surface grinding head 16, the left tool setting assembly 13, and the left grinding station 30 are all on a straight line; the centers of the right chamfering grinding head 19, the right surface grinding head 17, the right tool setting assembly 14, and the right grinding station 31 are all on a straight line.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
