Embodiment 1

[0035] This embodiment provides a silicon block size detection device, combined with such figure 1 , figure 2 and image 3 As shown, the silicon block size detection device includes: a first laser generator 105, a second laser generator 106, a third laser generator 107 and a processor (not shown in the figure).

[0036] Wherein, the first laser generator 105 is arranged on the left side of the conveyor belt 104, and the laser light emitted by it is perpendicular to the first surface 101 of the silicon block;

[0037] The second laser generator 106 is arranged on the right side of the conveyor belt 104, and the laser light emitted by it is perpendicular to the second surface 102 of the silicon block;

[0038] The third laser generator 107 is arranged above the conveyor belt 104, and the laser light emitted by it is perpendicular to the third surface 103 of the silicon block;

[0039] The processor is respectively connected with the first laser generator 105 , the second las...

Embodiment 2

[0063] This embodiment provides a silicon block size detection method, which is applied to the silicon block size detection device described in Embodiment 1, and the method includes the following steps:

[0064] Step S1: Place the silicon block on the conveyor belt so that the laser emitted by the first laser generator is perpendicular to the first surface of the silicon block, the laser emitted by the second laser generator is perpendicular to the second surface of the silicon block, and the third The laser emitted by the laser generator is perpendicular to the third surface of the silicon block;

[0065] In this embodiment, the conveyor belt keeps moving in one direction. After the silicon block is placed on the conveyor belt, the placement position of the silicon block needs to be manually or mechanically adjusted so that the laser light emitted by each laser generator is perpendicular to the respective corresponding laser beams. surface of the silicon block.

[0066] In t...

Abstract

The invention provides a device and method for detecting the size of a silicon briquette. The device for detecting the size of the silicon briquette comprises a first laser generator arranged on the left side of a conveyer belt, a second laser generator arranged on the right side of the conveyer belt, a third laser generator arranged above the conveyer belt and a processor, wherein lasers emitted by each laser generator are perpendicular to the corresponding surface of the silicon briquette, and the processor is connected with each laser generator. The processor is used for obtaining a first electric signal, a second electric signal and a third electric signal respectively, the first electric signal is generated when the lasers emitted by the first laser generator are blocked by the silicon briquette, the second electric signal is generated when the lasers emitted by the second laser generator are blocked by the silicon briquette, the third electric signal is generated when the lasers emitted by the third laser generator are blocked by the silicon briquette, the width of the silicon briquette is obtained through calculation according to the first electric signal and the second electric signal, and the height of the silicon briquette is obtained through calculation according to the third electric signal. By the adoption of the device and method for detecting the size of the silicon briquette, the size can be detected without the need for making contact with the silicon briquette, and the problem of edge breakage caused by contact measurement is avoided.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, and more specifically, to a silicon block size detection device and detection method. Background technique [0002] With the development of science and the advancement of technology, countries all over the world pay more and more attention to energy saving, emission reduction and environmental protection. As an important part of energy conservation and emission reduction projects, the photovoltaic industry has developed rapidly. The complete industrial chain of the photovoltaic industry is: silicon material→ingot casting workshop→silicon wafer workshop→battery workshop→component workshop→application system→energy storage system. [0003] Silicon wafers are one of the essential raw materials for making solar cells. The production process is roughly as follows: grow the purified and processed silicon materials and cast them into silicon ingots, and then cut the silicon ingots into silicon bl...
