Problems solved by technology

The Marr profiler is large in size, and when the probe is dirty, it will have a great impact on the measurement accuracy, making the test results inaccurate. Basically, it can only roughly measure the contour of the surface of the guide wheel, and cannot directly observe the groove shape. Accurately give the outline diagram and size, let alone the actual situation of the loss of the V-shaped groove of the guide wheel, so that the corresponding treatment of the guide wheel cannot be carried out in time, resulting in additional losses

Embodiment 1

[0061] The flow chart of the guide wheel profile detection method disclosed in this embodiment is as follows: figure 1 shown, including the following steps:

[0062] Step S101: using an industrial camera to take pictures of the surface of the guide wheel to obtain a contour image of the guide wheel;

[0063] It should be noted that there are many tools used to obtain the profile image of the guide wheel. In this embodiment, only the industrial camera is used as an example for illustration. Due to the high resolution of the industrial camera, the image of the profile image of the guide wheel is more accurate. Accurate, the profile image of the guide wheel obtained by photographing in this embodiment is as follows figure 2 shown, from figure 2 It can be seen from the figure that the outline image of the guide wheel is clear, and the actual situation of the V-shaped groove on the surface of the guide wheel can be accurately judged.

[0064] Step S102: According to the profile ...

Embodiment 2

[0067] The flow chart of the guide wheel profile detection method disclosed in this embodiment is as follows: image 3 shown, including the following steps:

[0068] Step S201: using an industrial camera to take pictures of the surface of the guide wheel to obtain a contour image of the guide wheel;

[0069] Step S202: Perform preprocessing on the outline image of the guide wheel, such as sharpening, increasing contrast, etc., to make the outline of the guide wheel clear, so as to facilitate subsequent calculation of various characteristic data of the V-shaped groove;

[0070] It should be noted that the preprocessing of the guide wheel profile image is only an optional step, and if the guide wheel profile image obtained in step S201 is clear enough, no preprocessing is required.

[0071] Step S203: According to the contour image of the guide wheel, calculate and obtain the characteristic data of the V-shaped groove of the guide wheel, and the characteristic data of the V-sha...

Embodiment 3

[0102] The embodiment of the invention discloses a guide wheel profile detection system, its structure diagram is as follows Figure 9 As shown, the system includes:

[0103] A guide wheel profile detection device 101, configured to obtain a guide wheel profile image;

[0104] A processing module connected to the guide wheel profile detection device, the processing module comprising:

[0105] The visual interface 102 enables the operator to observe the outline of the guide wheel in time;

[0106] The data processing unit 103 is used to calculate various feature data of the V-shaped groove of the guide wheel according to the outline image of the guide wheel, and the various feature data of the V-shaped groove include groove angle, groove height and groove distance.

[0107] Additionally, the system includes:

[0108] The alarm unit 108 is used for when the difference between the guide wheel profile and the standard profile exceeds the preset standard, and / or when the differe...

Abstract

The embodiment of the invention discloses a guide wheel outline detection method and system. The method comprises: taking a photo of the surface of a guide wheel by using an industrial camera to obtain the image of the outline of the guide wheel; and according to the image of the outline of the guide wheel, calculating the characteristic data of the V-shaped groove of the guide wheel, wherein the characteristic data of the V-shaped groove comprise groove included angle, groove height and groove space. In the embodiment of the invention, the outline of the guide wheel is detected by means of visual detection and the high-resolution industrial camera is used to take the photo of the surface of the guide wheel, so the actual conditions of the V-shaped groove on the surface of the guide wheel can be obtained accurately; according to the image of the outline of the guide wheel, which is obtained by taking the photo, the characteristic data of the V-shaped groove can be obtained; and thus, the specific loss condition of the V-shaped groove can be determined more accurately, so that the guide wheel can be treated correspondingly in real time, the influences on the slicing precision of silicon chips and production process are avoided, and unnecessary loss is avoided.

Description

technical field [0001] The present invention relates to the technical field of surface profile detection of a guide wheel, in particular to a method and system for detecting the profile of a guide wheel. Background technique [0002] Both the squarer for cutting silicon blocks and the slicer for cutting silicon wafers are provided with guide wheels. The surface of each guide wheel is covered with V-shaped grooves, which are mainly used to fix steel wires to cut silicon blocks or wafers. Due to the friction between the steel wire and the guide wheel during the operation of the machine, over time, the V-shaped groove of the guide wheel will be damaged by the steel wire, resulting in the inability to accurately fix the steel wire. [0003] With the development of the photovoltaic industry, the production schedule of silicon wafers is getting tighter and tighter, and because the integration of product production processes is getting higher and higher, the volume of products is ...
