Problems solved by technology

[0002] At present, the test lines in the large-scale production of photovoltaic cells do not have the real-time alarm function for single unqualified products. real-time alarm
When a large number of unqualified products with electrical parameters appear continuously, the test nurses can only observe the number of batteries in the container with the naked eye, or check it through the test software, so there is a certain lag, because the test nurses do not It is possible to pay attention to these data in real time. If the testers cannot find the problem in time, there will always be a large number of unqualified products
Assuming that within a certain period of time, due to abnormalities or failures in the production process or equipment, batches of substandard batteries may be produced, and during this period of time, the caretakers just did not observe these abnormalities, which will lead to continuous failure of substandard products. or mass production
The above phenomenon has become a weak link in the production process. Once there is a problem with the operation of equipment or employees, a large number of batteries with unqualified electrical parameters will appear, reducing the qualified rate of finished batteries.

Embodiment Construction

[0015] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] The standard for unqualified products with electrical parameters is: after the photovoltaic cell has been tested, its electrical performance indicators do not meet the set requirements, such as leakage current greater than 5 amps, fill factor less than 70, or conversion efficiency less than 15%.

[0017] According to a typical embodiment of the present invention, there is provided an alarm device for defective photovoltaic cells, such as figure 1 As shown, the alarm device includes: a photoelectric sensor 1, which is used to detect whether a battery passes through an unqualified position; Call the police.

[0018] When the photoelectric sensor 1 detects that there is a battery passing ...

Abstract

The invention discloses an alarming device and an alarming method for photovoltaic battery rejected products. The alarming device comprises a photoelectric sensor and an alarming device, wherein the photoelectric sensor is used for detecting whether a battery reaches a disqualified position or not; and the alarming device is connected with the photoelectric sensor and used for issuing an alarm when the photoelectric sensor detects that the battery reaches the disqualified position. When the photoelectric sensor detects the battery reaching the disqualified position, the alarming device issues the alarm, the alarming device is used for monitoring the rejected products in real time, so that the test monitoring personnel can get hold of information at first time when the rejected product appears so as to take relevant measures to reduce the production of mass rejected products or severe quality accident, assistance is provided for the test monitoring personnel, and certain contribution can be made for enhancing the qualification rate of the battery finished products.

Description

technical field [0001] The invention relates to the technical field of silicon solar cells, in particular to an alarm device and method for unqualified photovoltaic cells. Background technique [0002] At present, the test lines in the large-scale production of photovoltaic cells do not have the real-time alarm function for single unqualified products. Real-time alarm. When a large number of unqualified products with electrical parameters appear continuously, the test nurses can only observe the number of batteries in the container with the naked eye, or check it through the test software, so there is a certain lag, because the test nurses do not It is possible to pay attention to these data in real time. If testers cannot find problems in time, there will always be a large number of unqualified products. Assuming that within a certain period of time, due to abnormalities or failures in the production process or equipment, batches of substandard batteries may be produced, ...
