Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, and particularly relates to an isolation cover and a core conveying device. Background Art

During the transportation process, the core contacts the indoor environment, which will accelerate the temperature drop of the core and cannot play the role of preheating well. As a result, the hot pressing time of the core will be increased and the production efficiency of the equipment will be reduced.

[0003] The above problems need to be solved urgently at present. Summary of the Utility Model

[0029] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0030] Example 1, please refer to Figure 1-2, this embodiment provides an isolation cover 100, including a cover body 110 and at least one heating element 120; the heating element 120 is fixedly arranged in the inner wall of the cover body 110. By arranging the heating element 120 in the cover body 110 and covering the isolation cover 100 on the conveying mechanism 200, the battery cells in the conveying process are continuously heated, so as to meet the heat preservation requirement of the battery cells after preheating. At the same time, by arranging the cover body 110, the temperature loss can be reduced, thereby reducing the hot pressing time of the battery cells and improving the production efficiency of the battery cells.

[0031] Specifically, during the working process, the heating element 120 continuously releases heat energy to form a high-temperature environment to preheat the battery cells after blanking. During the conveying process, the battery cells still remain in a high-temperature environment, and the temperature loss of the battery cells will be greatly reduced.

[0032] It should be noted that the heating element 120 is any one or a combination of carbon heating, infrared heating, thermocouple heating, electromagnetic heating, and resistive heating.

[0033] In order to facilitate the upgrade of the existing conveying line, in this embodiment, the cover body 110 is in an inverted "匚" shape. The cover body 110 and the conveying line are installed in a covering manner, thereby reducing the production line upgrade cost.

[0034] In order to improve the heat preservation effect of the cover body 110, in this embodiment, an installation groove 111 is provided in the wall body of the cover body 110; a heat preservation layer is arranged in the installation groove 111. Wherein, the thickness of the heat preservation layer is greater than or equal to 50 mm. It should be noted that the heat preservation layer is formed by filling heat preservation cotton into the installation groove 111. In order to ensure the heat preservation effect of the cover body 110, the thickness of the heat preservation layer needs to be greater than 50 mm.

[0035] In order to prevent the hot air in the isolation cover 100 from affecting the workshop environment, in this embodiment, an exhaust vent 112 is provided at the top of the isolation cover 100; the exhaust vent 112 is communicated with an external exhaust duct. The hot air generated by the heating element 120 is discharged to the outside of the workshop through the exhaust duct.

[0036] In this embodiment, at least one observation window 113 is provided on the side wall of the isolation cover 100. When the battery cells are flowing, the staff can observe the running state of the battery cells on the logistics line through the observation window 113.

[0037] In this embodiment, the inner wall of the cover body 110 is a lattice reflection layer. The inner wall of the cover body 110 is formed into a lattice reflection layer through an electro-chemical matte treatment process. The multi-point diffused light radiation is uniform, so that the heat influence range of the heating element 120 is larger and the heating is more uniform.

[0038] Please refer to Figure 3-Figure 4This embodiment also provides a battery cell conveying device, including: a conveying mechanism 200, a support frame 300 and the isolation cover 100 as described above; the conveying mechanism 200 is fixedly arranged above the support frame 300; the isolation cover 100 covers the conveying mechanism 200.

[0039] In this embodiment, a temperature sensor 210 is fixedly mounted on the conveying mechanism 200. The temperature sensor 210 detects the high temperature environment in the isolation cover 100 and adjusts the temperature of the heating element 120 through a temperature control switch, thereby ensuring that the temperature in the isolation cover 100 is maintained at a desired temperature.

[0040] In summary, the present invention provides an isolation cover 100 and a battery cell conveying device. The isolation cover 100 continuously heats the battery cells during conveyance by disposing a heating element 120 within the cover body 110 and covering the conveying mechanism 200 with the isolation cover 100, thereby meeting the thermal insulation requirements of the preheated battery cells. Furthermore, the provision of the cover body 110 reduces temperature fluctuations, thereby shortening the hot pressing time of the battery cells and improving battery cell production efficiency.
