[0027] Example 1

[0028] In order to further improve efficiency in the photovoltaic market, the application of single crystal rectangular rods in the market has reached more than 60%. Among them, the grinding in the machining workshop needs to use the wide surface of the single crystal rectangular rod as the reference surface and the narrow surface as the vertical surface for processing. Then, when gluing in the slicing workshop, the narrow surface of the single crystal rectangular rod is used as the reference surface and the wide surface of the rectangle is used as the vertical surface. In view of this situation, many manufacturers currently use the method of manually measuring the size and then marking it, so as to process and glue the single crystal rectangular rod. However, the method of manually measuring the size and then marking it is more likely to cause batch errors, causing the grinding to spit out the rod, and the slicing end to stick to the reverse according to the marking direction, resulting in batch downgraded slices, which seriously affects the quality.

[0029] Therefore, the utility model provides a fool-proof positioning tool for a single crystal rectangular rod, by which the length of the positioning plate 1 in the horizontal direction is consistent with the length of the end face of the single crystal rectangular rod, thereby making it easy to locate the narrow side and the wide side of the single crystal rectangular rod. The use of the positioning plate 1 can avoid manual measurement errors and reduce cost losses.

[0030] Specifically, Figure 1 As shown, a single crystal rectangular ingot fool-proof positioning tool is applied to the end face of the ingot 6 to be positioned, the end face is in the shape of a rectangle, and the rectangle is composed of two first sides and two second sides, the length of the first side is greater than the length of the second side, and includes a positioning plate 1, the rectangular plate is horizontally arranged on the end face of the ingot 6 to be positioned, and the back of the rectangular plate is in contact with the end face of the ingot 6 to be positioned.

[0031] The positioning plate 1 is a rectangular plate consisting of two long sides and two short sides, wherein the length of the long side is equal to the length of the first side or the second side, and an identification groove 2 parallel to the long side is provided on the rectangular plate, wherein the identification groove 2 extends horizontally along the long side.

[0032] Preferably, one end of the marking groove 2 is connected to the front of the positioning plate 1 , and the other end of the marking groove 2 passes through the positioning plate 1 and is connected to the end surface of the crystal rod 6 to be positioned.

[0033] Preferably, the marking groove 2 is in the shape of a left-right double arrow, and both ends of the arrows of the left-right double arrow extend horizontally toward both sides of the long side respectively.

[0034] Preferably, a fixing plate 3 is vertically disposed on one side of the positioning plate 1 , one end of the fixing plate 3 is fixedly connected to one side of the positioning plate 1 , and the other end of the fixing plate 3 extends along the side of the crystal rod 6 to be positioned.

[0035] Preferably, a limiting plate 4 is vertically arranged on the top of the positioning plate 1, one end of the limiting plate 4 is fixedly connected to the top of the positioning plate 1, and the other end of the limiting plate 4 extends along the top of the crystal rod 6 to be positioned.

[0036] Preferably, the top of the fixing plate 3 is at the same level as the top of the positioning plate 1, and the side of the positioning plate 1 is connected to the top of the fixing plate 3. The purpose is that the limit plate 4 and the fixing plate 3 can fit with one side of the crystal rod 6 to be positioned, which is convenient for the staff to judge whether the long side of the positioning plate 1 and the side length of the crystal rod 6 to be positioned coincide, and it is convenient for the staff to place the positioning tool on the end face of the crystal rod 6 to be positioned.

[0037] Preferably, the shape of the limiting plate 4 includes a triangle, a square, and a rectangle. Preferably, a handle 5 is provided on the side of the fixing plate 3 away from the crystal rod 6 to be positioned, and the handle 5 is convenient for the staff to take it by hand.

[0038] Based on the above principles, the utility model is further described:

[0039] At present, the length of the first side length of the end face of the single crystal rectangular ingot is generally set to 183.75cm, 187.75cm, 191.5cm, etc., and the length of the second side length is generally set to 182cm, so that the length of the first side length of the end face of the single crystal rectangular ingot is greater than the length of the second side length. Specifically, when the end face of the single crystal rectangular ingot takes the first side length as the side length in the horizontal direction, that is, the first side length of the end face of the single crystal rectangular ingot is placed in the horizontal direction, the end face of the single crystal rectangular ingot is a wide face; when the end face of the single crystal rectangular ingot takes the second side length as the side length in the horizontal direction, that is, the second side length of the end face of the single crystal rectangular ingot is placed in the horizontal direction, the end face of the single crystal rectangular ingot is a narrow face.

[0040] Among them, when grinding down the single crystal rectangular ingot, the wide surface of the single crystal rectangular ingot needs to be used as the reference surface and the narrow surface as the vertical surface for processing; when gluing the single crystal rectangular ingot, the narrow surface of the single crystal rectangular ingot needs to be used as the reference surface and the wide surface as the vertical surface for processing. Therefore, if the staff makes a mistake in manually measuring and positioning the narrow and wide surfaces of the single crystal rectangular ingot, it will cause problems in the subsequent two work procedures, making the single crystal rectangular ingot opposite to the line mark direction after the whole knife cutting, and it will be reduced to a B piece, which seriously affects the quality and greatly increases the production cost. In addition, the length and width of the end face of the single crystal rectangular ingot are generally not too different, so it is easier for the staff to make mistakes when doing manual measurement.

[0041] Therefore, in response to the above situation, the utility model provides a single crystal rectangular crystal rod fool-proof positioning tool, including a positioning plate 1, wherein the positioning plate 1 is a rectangular plate, and the rectangular plate is composed of two long sides and two short sides, the length of the long side is equal to the length of the first side length or the second side length, and the rectangular plate is provided with an identification groove 2 parallel to the long side, and the identification groove 2 extends horizontally along the long side, and the wide side and narrow side of the crystal rod 6 to be positioned are positioned by making the length of the long side of the rectangular plate equal to the length of the first side length or the second side length, so that the staff can mark and position the wide side and narrow side of the crystal rod 6 to be positioned through the identification groove 2, thereby preventing the staff from making mistakes in measurement.

[0042] Example 2

[0043] Based on Example 1, in this embodiment, Figure 2 , Figure 3 As shown, when the length of the long side of the rectangular plate is equal to the length of the first side, and the length of the second side is less than the length of the first side, the length of the short side of the rectangular plate can be selected to be equal to, less than, or greater than the length of the second side. In this embodiment, the length of the short side of the rectangular plate is less than the length of the second side. When the rectangular plate is placed horizontally on the end face of the crystal rod 6 to be positioned, that is, the long side of the rectangular plate is in the horizontal direction, if the length of the side of the crystal rod 6 to be positioned in the horizontal direction coincides with the length of the long side of the rectangular plate, then the length of the side of the crystal rod 6 to be positioned in the horizontal direction is the first side length, indicating that the end face of the crystal rod 6 to be positioned is a wide face; if the length of the side of the crystal rod 6 to be positioned in the horizontal direction does not coincide with the length of the long side of the rectangular plate, and the length of the side of the crystal rod 6 to be positioned in the vertical direction is exposed outside the positioning plate 1, then the length of the side of the crystal rod 6 to be positioned in the horizontal direction is the second side length, indicating that the end face of the crystal rod 6 to be positioned is a narrow face.

[0044] Example 3

[0045] Based on Example 1, in this embodiment, Figure 4 , Figure 5 As shown, when the length of the long side of the rectangular plate is equal to the length of the second side, when the rectangular plate is placed horizontally on the end face of the crystal rod 6 to be positioned, that is, the long side of the rectangular plate is in the horizontal direction, if the side length of the crystal rod 6 to be positioned in the horizontal direction coincides with the length of the long side of the rectangular plate, then at this time, the side length of the crystal rod 6 to be positioned in the horizontal direction is the second side length, which indicates that the end face of the crystal rod 6 to be positioned is a narrow face; if the side length of the crystal rod 6 to be positioned in the horizontal direction does not coincide with the length of the long side of the rectangular plate, and at this time, the side length of the crystal rod 6 to be positioned in the horizontal direction will be exposed outside the positioning plate 1, then at this time, the side length of the crystal rod 6 to be positioned in the horizontal direction is the first side length, which indicates that the end face of the crystal rod 6 to be positioned is a wide face.

[0046] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
