Description

Technical Field

[0001] This invention relates to the field of silicon rod processing equipment technology, specifically to a cutting and grinding integrated machine and its high-efficiency grinding device. Background Technology

[0002] With the development of the photovoltaic industry, the demand for half-cell solar cells is gradually expanding, leading to a growing demand for half-rod silicon wafers. Half-rods can be formed by slitting the previously common square silicon rods, specifically by cutting the square silicon rod along its length to create two half-rods. This allows for the reuse of most existing production lines; the entire production process from round silicon rods to silicon wafers only requires the addition of a half-slitting operation on the square silicon rods. However, the production efficiency of some newly applied equipment in the industry remains low. For example, the "Integrated Cutting and Grinding Machine and its Control Method, Medium, and Computer Equipment" disclosed in Chinese Invention Patent Application Publication No. CN 117140763 A, the "Integrated Cutting and Grinding Machine for Square Silicon Rods" disclosed in CN 115946248 A, and the "Integrated Cutting and Grinding Machine for Square Silicon Rods" disclosed in CN 115871115 A are all new applications of equipment for cutting square silicon rods into two square silicon rods (half-rods), but their efficiency remains low.

[0003] Therefore, the researchers of this applicant believe it is necessary to improve or optimize the existing integrated cutting and grinding machine and / or its components to increase its production efficiency. Summary of the Invention

[0041] Among them, reference Figure 1 As shown, the first direction is the same as the direction of the first track 11, and the second direction is perpendicular to the first direction and forms a horizontal plane with the first direction. The structures of the first clamping group 21 and the second clamping group 22 can be exactly the same or different, as long as they can perform the function of clamping the square silicon rod 01. The first track 11 and the second track 12 can be exactly the same or different.

[0044] like Figures 2 to 4 As shown, the first surface grinder 41 includes a first surface grinder head 411. The first surface grinder head 411 is mounted on a first surface grinder support 412, which is flexibly mounted on the grinding frame 30 via a first surface grinder lifting mechanism 413. The first surface grinder lifting mechanism 413 can be a linear guide or a lead screw structure.

The first angle grinding support 512 is rotatably mounted on the first lifting support 511 and can rotate to the left or right sides of the first lifting support 511 (e.g., ...). Figures 2 to 4 If it is defined as rotating to the right, then... Figure 5 and Figure 6 The rotation is defined as moving to the left (of course, during the rotation, it will inevitably pass through various intermediate positions) so that the first chamfering grinding head 513 on the first angle grinder support 512 can chamfer both sides of the lower / below / lower square silicon rod, thereby enabling the first chamfering grinding head 513 to chamfer both sides of the square silicon rod. The first angle grinder support 512 can be rotated relative to the first lifting support 511 using various suitable existing technologies.

[0048] like Figures 1 to 6 As shown, the second chamfering grinder 52 includes a second lifting support 521, a second angle grinding support 522, and a second chamfering grinding head 523. The second lifting support 521 is movably mounted on the grinding frame 30 via a second angle grinding lifting mechanism 524. The second angle grinding support 522 is rotatably mounted on the second lifting support 521 and can rotate to either side of the second lifting support 521 (e.g., ...). Figures 2 to 4 If it is defined as rotating to the right, then... Figure 5 and Figure 6The rotation is defined as moving to the left (of course, the rotation will inevitably pass through various intermediate positions) so that the second chamfering grinding head 523 on the second angle grinder support 522 can chamfer both sides of the other square silicon rod, thus enabling the second chamfering grinding head 523 to chamfer both sides of the square silicon rod. The rotation of the second angle grinder support 522 relative to the second lifting support 521 can be achieved using various suitable existing technologies.

[0049] The chamfering angle can be 60 degrees, 30 degrees, 45 degrees, 40 degrees, 50 degrees, or other suitable angles. The structures of the first chamfering grinder 51 and the second chamfering grinder 52 can be completely identical, or at least one of the four groups—the first lifting support 511 and the second lifting support 521, the first angle grinding support 512 and the second angle grinding support 522, the first chamfering grinding head 513 and the second chamfering grinding head 523, the first angle grinding lifting mechanism 514 and the second angle grinding lifting mechanism 524—can be completely identical, or all of them can be different. Furthermore, the first angle grinding lifting mechanism 514 and / or the second angle grinding lifting mechanism 524 can be a linear guide or a lead screw structure. Additionally, the first angle grinding lifting mechanism 514 and / or the second angle grinding lifting mechanism 524 can also be vertically and flexibly mounted on the grinding frame 30 in other ways.

[0050] In a preferred embodiment, reference Figures 1 to 6 As shown, the center distance between the first surface grinder head 41 and the second surface grinder head 42 is equal to the center distance between the first angle grinder support 512 and the second angle grinder support 522.

The rotation center line of the second surface grinder head 42 and the rotation center line of the second angle grinder support 522 are coplanar (both are on the same plane) and parallel to the direction of the first track 11 or the second track 12.

[0051] In addition, it should be noted that, in Figures 2 to 6 The specific connection structure between the grinding frame 30 and the first track 11 and the second track 12 is not shown in the diagram. Those skilled in the art can implement this using various suitable existing technologies or common knowledge. No specific limitations are imposed on the specific configuration in this application.

[0052] In a preferred embodiment, reference Figure 1 As shown, the first track 11 and the second track 12 are located on the same horizontal plane. Alternatively, they may not be located on the same horizontal plane, in which case the left and right sides of the grinding frame 30 will have different heights when they mate with the tracks.

[0053] In an alternative embodiment, reference Figures 1 to 6In this configuration, when the first angle grinder support 512 rotates to the right side of the first lifting support 511, the second angle grinder support 522 also rotates to the right side of the second lifting support 521. When the first angle grinder support 512 rotates to the left side of the first lifting support 511, the second angle grinder support 522 also rotates to the left side of the second lifting support 521. The rotation of the two supports can be synchronized or asynchronous; they can both be on the left side when needed and on the right side when needed.

The center-to-center distance between the rotation center lines of the angle grinding supports (512 / 522) of the two chamfering grinders (51 / 52) is equal to the center-to-center distance between the two surface grinders (41 / 42). In both the surface grinder assembly 40 and the chamfering grinder assembly 50, the rotation center line of the surface grinder head (411 / 421) operating on the same square silicon rod is coplanar with the rotation center line of the corresponding angle grinding support (512 / 522) and parallel to the track direction.
