Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be described in detail below, obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The invention provides a temperature measuring device, which is suitable for measuring the temperature of a hot air pipe in an NPC welding machine, and can accurately obtain the temperature value of the battery sheet surface during hot air welding by simulating the processing environment during battery sheet welding. Therefore, when the battery sheet is actually welded, the temperature of the surface of the battery sheet can be effectively controlled to avoid cracks.

[0028] Such as figure 1 As shown, the temperature measurin...

Abstract

The invention discloses a temperature measuring device and a temperature measuring method. The temperature measuring device comprises an insulated body, a thermocouple, and a temperature measuring instrument, wherein the insulated body is provided with a mounting groove; the thermocouple is arranged in the mounting groove; a wiring groove is formed in the insulated body; the wiring groove is communicated with the mounting groove; a wire is arranged in the wiring groove; one end of the wire is electrically connected with the thermocouple and the other end extends out from the wiring groove; and the temperature measuring instrument is electrically connected with the other end of the wire for receiving electrical signals converted by the thermocouple. The temperature measuring device of the invention can accurately acquire the temperature value on the surface of a cell in the case of hot air welding through simulating the processing environment when the cell is welded, and thus, during the actual welding process of the cell, the temperature on the surface of the cell can be effectively controlled, and cracking can be prevented.

Description

technical field [0001] The invention relates to a temperature measuring device and a temperature measuring method, in particular to a measuring device and method for measuring the surface temperature of a battery sheet in a hot air welding process of a battery sheet. Background technique [0002] Cells, also known as solar cells, can be divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon according to different materials. At present, during the production and processing of battery sheets, NPC welding machines are often used for hot air welding of battery sheets. In the hot air welding process of the battery sheet, the temperature of the surface of the battery sheet has a great influence on the quality of the welded battery sheet. Specifically, if the surface temperature of the battery sheet is too high, it will cause the battery sheet to crack. [0003] In order to control the temperature of the cell hot air welding, it needs to be effective...
