Problems solved by technology
If the tab welding strength is too weak, the internal resistance of the lithium-ion battery will increase, and it will become hot during charging and discharging, causing the diaphragm to melt and cause a short circuit. In addition, it may even fall off during the winding process of the lithium-ion battery, causing the lithium-ion battery Roll core scrap

The invention discloses an insufficient solder detection device for a tab of a lithium ion battery tableting machine. The detection devicve comprises an unwinding roller. a winding roller, a pole piece clamping device, a tab clamping device, a high-frequency vibrator detecting circuit, a blast pipe, and an air blower. According to the detection device provided by the invention, a high-frequency vibrator is used as a power source to provide a force for the tab to leave the pole piece and thus the tab in an insufficient solder is disconnected with the pole piece under the effect of the force; and the detecting circuit is disconnected and a light-emitting diode quenches to realize an indication effect. Therefore, the welding state of the battery pole piece can be detected rapidly and accurately; a phenomenon that the worker needs to determine the tab welding state during the lithium ion battery tableting process with naked eyes is avoided and thus the working fatigue of the worker is reduced.
Description
technical field [0001] The invention relates to the field of lithium ion battery production equipment. More specifically, the present invention relates to a detection device for false welding of tabs of a lithium-ion battery production machine. Background technique [0002] In the production process of lithium-ion batteries, a batch coating process is usually used to evenly coat the stirred slurry on aluminum foil or copper foil. The aluminum foil or copper foil that is not coated with the slurry is the coating interval, which is called the blank area. In this area, aluminum strips are welded to aluminum foils, or nickel strips to copper foils, again using ultrasonic welding. The process of welding aluminum strips and nickel strips is called sheet making. The welded aluminum strips and nickel strips are the tabs of the lithium-ion battery described in this patent, and the tabs are used to conduct the current when the battery is charged and discharged. [0003] During the...
