Description

Technical Field

[0001] The invention belongs to the technical field of battery production detection, and in particular relates to a lead paste follow-up temperature detection device. Background Art

[0002] Lead paste is the main component material of battery plates. One of the key factors affecting the composition and performance of lead paste is the temperature during the lead paste preparation process. There are currently two main ways to monitor the paste temperature: 1. Detect the temperature of the lead pot wall. The actual temperature of the lead paste and the detected temperature are quite different, and the difference value changes from positive to negative at different stages of the paste preparation, making it difficult to accurately measure the temperature of the paste preparation process; 2. Detect the air temperature above the lead pot, which cannot show the actual temperature value of the lead paste. In the process of cooling and pumping negative pressure, the lead paste temperature will be higher than the measured temperature, and the difference value changes with the negative pressure.

[0003] In order to overcome the drawbacks of the above two methods, CN110068402A discloses a high-precision lead paste follow-up temperature recording device, including an insulating shell, in which a temperature probe, a data transmitter and a temperature recorder are installed. The temperature probe, the data transmitter and the temperature recorder are connected in sequence, and the temperature probe passes through the side wall of the insulating shell and extends to the outside. A power supply is also provided in the insulating shell. Although the temperature recording device can move up and down as a whole with the lead paste when in use, it cannot keep the end with the temperature probe installed facing downward all the time in actual use.
