Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, in an embodiment of the present invention, a baking tray for lithium battery cells includes a tray 1 having a frame structure, where the tray 1 includes a bottom plate 11, a first side plate 12, a second side plate 13, a third side plate 14, and a fourth side plate 15, where the first side plate 12, the second side plate 13, the third side plate 14, and the fourth side plate 15 are distributed in a rectangular shape and sequentially connected end to end, the first side plate 12 is parallel to the third side plate 14, the second side plate 13 is parallel to the fourth side plate 15, the bottom plate 11 is provided with cell positioning holes 2 arranged in an array, the cell positioning holes 2 are circular, and the size of the cell positioning holes 2 is matched with that of cylindrical battery cells to fix the cylindrical battery cells; every three rows of electric core locating holes 2 are a set of, sets up the ventilation hole of arranging in line on every adjacent two bottom plates 11 between electric core locating hole 2 of group, and ventilation hole 3 not only can increase the ventilation effect of tray, improve rate of heat dissipation, has still alleviateed the tray dead weight simultaneously, the transport of being convenient for. The two sides of the top end of the first side plate 12 are respectively provided with a first positioning pin 4, the two sides of the top end of the third side plate 14 are respectively provided with a first positioning pin 4, and the bottoms of the first side plate 12 and the third side plate 14 are provided with a limiting hole 5 for accommodating the first positioning pin 4. The accurate positioning of the tray in the stacking process can be guaranteed by the matching connection of the limiting holes 5 of the first positioning pins 4, and the stability in the stacking process can be improved.
