Novel jig for confirming position of guide wheel

Abstract

The utility model provides a novel jig for confirming the position of a guide wheel, which is used for a crystal bar slicing process. The jig is composed of an outer frame and a clamping groove and can be adjusted to a certain degree according to guide wheels of different specifications. When in use, one of the adjacent guide wheels is placed in the jig, if the other guide wheel can be placed simultaneously, the two guide wheels are in the same plane, otherwise, the two guide wheels are not in the same plane. The jig is simple in structure and convenient to manufacture and operate, can be switched according to guide wheels of different specifications, can simply and quickly confirm the horizontal state of the guide wheels, and reduces wire breakage caused by the fact that the guide wheels are not in the same plane.

Description

Technical Field

[0001] The utility model mainly relates to a manufacturing process in the production process; specifically, it relates to a new fixture for confirming the position of guide wheels. Background Art

[0002] There is a slicing process in the semiconductor wafer manufacturing process, which is used to cut a complete ingot into multiple wafers with the same thickness for subsequent manufacturing processes. Among them, there is a method of using a diamond wire or a slurry wire wound around a main wheel for ingot cutting, which is collectively referred to as wire cutting hereinafter. For wire cutting, when the diamond wire or the slurry wire is taken out from the wire wheel and wound around the main wheel, it needs to be redirected by multiple guide wheels so that the diamond wire or the slurry wire can be wound around the main wheel at the correct position. At this time, a fixture is required to confirm whether two adjacent guide wheels are in the same plane. However, in the current process, a straight ruler is used as the fixture. When using it, the straight ruler is attached to the same side of two guide wheels, and whether there is a gap is observed to confirm whether the guide wheels are in the same plane. However, different results may occur when checking the same set of guide wheels due to different operators, which may cause wire breakage due to the guide wheels not being in the same horizontal plane, resulting in an increase in wire consumption and time during cutting, and may also lead to product scrapping. This fixture improves the original fixture that can only confirm one side of the guide wheel. The guide wheel is placed in the fixture slot to ensure that the guide wheels can be in the same plane, reducing wire breakage caused by different positions of the guide wheels. Summary of the Utility Model

[0003] In order to improve the above situation, the purpose of the utility model is to provide a new fixture for confirming the position of guide wheels.

[0004] The purpose of the utility model can be achieved by the following technical solutions: The fixture consists of a slot and an outer frame. The slot is set in the outer frame, with a simple structure, which is convenient for manufacturing and operation.

[0005] In an embodiment of the utility model, the fixture can be adjusted in a certain proportion according to the width of the guide wheel and the distance between adjacent guide wheels.

[0006] In an embodiment of the utility model, the fixture restricts the movement of the guide wheel through the left and right side frames, playing a role in confirming the position of the guide wheel.

[0007] Based on the above, the advantages and characteristics of the embodiment of the utility model are that this fixture has a simple structure, is convenient for manufacturing and operation, and can be switched according to different specifications of guide wheels. It can simply and quickly confirm the horizontal state of the guide wheels, reducing wire breakage caused by the guide wheels not being in the same plane. This fixture can be applied to the ingot slicing process, with simple manufacturing and operation, and can reduce wire breakage caused by the guide wheels not being in the same plane.

[0011] 101 Outer frame

[0012] 102 Card slot Specific implementation manners

[0013] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Apparently, the described embodiments are some but not all of the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0014] The following makes a detailed description of the specific implementation manners of the utility model with reference to the accompanying drawings:

[0015] A new type of jig for confirming the position of a guide wheel is composed of an outer frame 101 and a card slot 102, and the jig can be switched according to the size of the guide wheel specifications, and the position of the card slot 102 in the outer frame 101 corresponding to the guide wheel is set. The outer frame 101 of the jig plays a limiting role, and the guide wheel is stuck in the card slot 102. If two guide wheels can be placed in the jig card slot at the same time, it means that the guide wheels are on the same plane of the card slot 102 in the outer frame 101, and the horizontal state of the guide wheel is judged according to the position of the card slot 102 in the outer frame 101.

[0016] A new type of jig for confirming the position of a guide wheel is composed of an outer frame and a card slot, and can be adjusted according to different guide wheel specifications. This jig can be applied to the crystal bar slicing process, is simple to manufacture and operate, can simply and quickly confirm the horizontal state of the guide wheel, and reduce wire breakage caused by the guide wheels not being on the same plane.

Claims

1. A new type of jig for confirming the position of a guide wheel, characterized in that, The jig includes a card slot and an outer frame. A card slot is provided in the middle of the outer frame. According to the position of the guide wheel, the corresponding position of the card slot in the outer frame is set, and the guide wheel is clamped in the card slot. If two guide wheels can be placed in the card slot of the jig at the same time, it means that the guide wheels are on the same plane of the card slot in the outer frame, and the horizontal state of the guide wheel is judged according to the position of the card slot in the outer frame.
