Abstract

The orientation tool for the silicon single crystal rod comprises a support (1), wherein two mounting frames (2) are symmetrically arranged on two sides of the top of the support (1), a polytetrafluoroethylene rod (3) is mounted on each mounting frame (2), and two ends of the polytetrafluoroethylene rod (3) are mounted on the mounting frames (2) through bearings (4); the support (1) is a rectangular frame, and a guide wheel (5) is installed at the bottom of the support (1). The utility model can rotate the section angle of the single crystal silicon rod at will and can orient according to any crystal orientation; the labor intensity of detection personnel is reduced, the detection time is saved, and therefore the silicon single crystal rod can be conveniently and quickly oriented, and meanwhile, the safety of materials is guaranteed.

Description

A directional frock for single crystal silicon rod

Technical Field

The utility model relates to an orienting device, more specifically the orientation frock that relates to a be used for single crystal silicon rod that says so belongs to orienting device technical field.

Background

The silicon single crystal rod needs to be subjected to the processes of cutting, squaring, grinding, slicing and the like during processing, the quality of the squaring quality directly influences whether the subsequent processes can be smoothly carried out, and the quality of the squaring quality directly influences the quality of the squaring due to the high and low crystal orientation detection precision. At present, most of crystal orientation detection adopts an optical fiber type laser sensor, but the sensor has high requirements on the external environment and higher cost, is not suitable for being used under complicated and variable conditions, and cannot meet the use requirements.

Disclosure of Invention

An object of the utility model is to the above-mentioned problem that exists among the prior art, a tooling device for single punch press die supporting arm machining center is provided.

In order to achieve the above object, the technical solution of the present invention is: the utility model provides an orientation frock for single crystal silicon rod, includes the support, support top bilateral symmetry be provided with two mounting brackets, install the polytetrafluoroethylene stick on the mounting bracket, polytetrafluoroethylene stick both ends pass through the bearing and install on the mounting bracket.

The support be the rectangle frame, the guide pulley is installed to the support bottom.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model can rotate the section angle of the single crystal silicon rod at will and can orient according to any crystal orientation; the labor intensity of detection personnel is reduced, the detection time is saved, and therefore the silicon single crystal rod can be conveniently and quickly oriented, and meanwhile, the safety of materials is guaranteed.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a support 1, a mounting rack 2, a polytetrafluoroethylene rod 3, a bearing 4 and a guide wheel 5.

Detailed Description

The invention is described in further detail below with reference to the following description of the drawings and the detailed description.

Referring to fig. 1, the orientation tool for the silicon single crystal rod comprises a support 1, wherein two mounting frames 2 are symmetrically arranged on two sides of the top of the support 1, a polytetrafluoroethylene rod 3 is mounted on the mounting frames 2, two ends of the polytetrafluoroethylene rod 3 are mounted on the mounting frames 2 through bearings 4, the polytetrafluoroethylene rod 3 is concentric with the bearings 4, and the circle centers of the polytetrafluoroethylene rod 3 and the bearings 4 are the same.

Referring to fig. 1, the bracket 1 is a rectangular bracket, and a guide wheel 5 is installed at the bottom of the bracket 1.

Referring to fig. 1, the polytetrafluoroethylene rod 3 of the orientation tool can roll on the mounting rack 2, and a single crystal silicon rod to be detected is placed on the polytetrafluoroethylene rod 3, so that the single crystal silicon rod can freely rotate, and the end face direction of the single crystal silicon rod can be adjusted at will; the position can be determined by positioning the crystal orientation movement according to <111>, <100>, <110> and the like through the guide wheel 5.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.
