Description

Technical Field

[0001] The utility model relates to the technical field related to lithium battery production, in particular to a device that effectively prevents a bare battery from tilting and causing ignition in a film cutting machine. Background Art

[0002] Lithium batteries contain pole pieces. Lithium battery pole piece coating refers to a process in which a stirred slurry is evenly coated on a foil and the organic solvent in the slurry is dried. The coating process is a very critical process in the production of lithium batteries. The coating surface density is one of the most important technical parameters in the production of lithium-ion batteries, which directly determines the battery capacity, internal resistance, cycle life and safety. If the coating surface density is too small, the battery capacity will not reach the nominal capacity. If the coating surface density is too high, the positive electrode capacity cannot be fully utilized, which is easy to cause material waste. In severe cases, excessive lithium precipitation in the positive electrode forms lithium dendrites that pierce the battery diaphragm to cause an internal short circuit, causing safety hazards. Inconsistent surface density makes it difficult to maintain a constant pole piece baking temperature. Too high a temperature can easily cause the pole piece to crack. If the temperature is low, the pole piece cannot be completely dried, which will affect the subsequent pole piece rolling and cannot guarantee the performance consistency of the battery pole piece. Therefore, there is an urgent need for a device that can effectively prevent the bare battery from tilting and causing sparks in the film cutter.

[0003] The film cutting machine device currently used has the problem that the bare batteries are easily skewed on the flow belt before being packed after laser film cutting, and there is a jamming phenomenon when pushing the materials into the box, causing sparking. Utility Model Content

Through the set blocking mechanism 4, it is convenient for the battery column 3 to be transported through the flow belt 2. When the battery column 3 is full of material, the full material sensor 5 senses that the battery column 3 is full of material, and transmits a stop signal to the flow belt 2 through the full material sensor 5, thereby stopping the flow belt 2. The lifting rod 404 can be driven by the first cylinder 403 in the blocking mechanism 4 to drive the baffle 405 to be pulled down, and the baffle 405 is used to block and separate the battery column 3, so that the battery to be pushed into the receiving box 7 can be separated from the incoming battery, which not only reduces the resistance of pushing the material into the box, but also prevents the incoming battery from being skewed on the flow belt 2.
