[0002] Multi-wire saw is a commonly used device in the 12-inch silicon rod slicing process, such as Figure 1 As shown, the steel wire transmission mechanism of the equipment mainly consists of a pay-off wheel, a take-up wheel, a take-up and pay-off reciprocating machine, a wire mesh master and slave wheel, and multiple variable guide wheels. After replacing the take-up wheel bobbin, due to the change in mechanical position, the two axial reciprocating end points of the take-up reciprocating machine 2 are generally repositioned. When confirming whether the position of the take-up reciprocating machine 2 is aligned with the edge of the take-up wheel 3, visual inspection is generally used. However, due to lack of experience or other factors, the steel wire 4 often has uneven arrangement in the bobbin during take-up, forming bulges or depressions at both ends. This will cause fluctuations in the steel wire tension, affecting product parameters. In severe cases, it may cause the wire mesh to break, which will lead to the scrapping of the entire crystal ingot. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 2 As shown, the silicon rod multi-wire sawing machine take-up wheel reciprocating machine alignment tool 1 (hereinafter referred to as the alignment tool) proposed by the present invention is used to confirm the two axial reciprocating motion end positions of the take-up reciprocating machine 2 after replacing the take-up wheel 3 bobbin.

[0021] like Figure 3 、 Figure 4 The alignment tool 1 shown is composed of a reciprocating wheel sleeve 11, a rocker arm 12, a pin 13, a bearing 14, a mounting ring 15, etc. The rocker arm 12 is mounted on the bearing seat of the reciprocating wheel sleeve 11 using the pin 13, bearing 14, mounting ring 15, nut 16, etc., so that the rocker arm 12 rotates smoothly and maintains rotation accuracy.

[0022] like Figure 5 As shown, the reciprocating wheel sleeve 11 is in the form of a 1 / 2 circular ring, and a wheel sleeve groove 111 is provided on the inner arc surface of the circular ring along the arc direction. The size of the reciprocating wheel sleeve is determined according to the size of the reciprocating wheel used, so that the reciprocating wheel forms a sliding fit when embedded in the reciprocating wheel sleeve; a bearing seat 112 is provided on one side of the reciprocating wheel sleeve; the wheel sleeve groove 111 and the bearing seat 112 are both symmetrically arranged with the center plane in the height direction of the circular ring as the symmetry plane.

[0023] like Figure 6 As shown, the rocker arm 12 is a long rectangular rod, with a shaft sleeve 121 and a measuring disk 122 respectively arranged in the center on both sides. The shaft sleeve 121 is used to connect with the reciprocating wheel sleeve 11. The measuring disk 122 is marked with scales. The 0 scale position is colinear with the center line of the rocker arm 12, and the other scales are arranged symmetrically on both sides of the 0 scale line.

[0024] The alignment tool of the utility model is made entirely of 304 stainless steel, which ensures strength and reduces adverse effects caused by component deformation.

[0025] In actual application, the operation process of the alignment tool in the utility model is:

[0026] After replacing the take-up wheel 3 bobbin, align the tool 1 according to Figure 1 , it is installed on the take-up reciprocating machine 2 in the manner shown in the figure. The reciprocating machine is controlled to move forward or backward in the axial direction on the equipment operation interface. It stops moving when it reaches the alignment position visually. At this time, the rocker arm 12 is rotated to make it rest on the take-up wheel 3 spool. If the inner wall of the take-up wheel 3 spool is aligned with the 0 scale line of the measuring disk at this time, it is determined that the alignment position has been reached, and this position coordinate is confirmed on the equipment operation interface. If the inner wall of the take-up wheel 3 spool is not aligned with the 0 scale line of the measuring disk, the position is adjusted again based on the distance reading between the 0 scale line and the inner wall of the take-up wheel 3 spool read by the measuring disk until the inner wall of the take-up wheel 3 spool is aligned with the 0 scale line of the measuring disk, and the position coordinate is confirmed on the equipment operation interface.

[0027] The alignment tooling of the utility model has a simple structure and is easy to operate. It can effectively assist production personnel in aligning the take-up wheel reciprocating machine, improve alignment accuracy and work efficiency, and avoid product losses caused by uneven steel wire arrangement.
