BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0010] Figure 1 It is a structural schematic diagram of the utility model;

[0011] Figure 2 It is a schematic diagram of the back side of the utility model. DETAILED DESCRIPTION

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0013] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: a highly compatible winding blister tray, comprising a blister tray body 1, a bare battery core limiting groove 2 is arranged on the blister tray body 1, a whole piece of EVA foam pad 3 is arranged on the bare battery core limiting groove 2, blocks wrapped with a foam silicone sleeve 4 are arranged on both sides of the bare battery core limiting groove 2, a long block 5 is arranged at the bottom of the bare battery core limiting groove 2, and a long strip of soft foam 6 is attached to the inner surface of the long block 5, EVA foam 7 is inlaid on both sides of the battery core ear position, a QR code label position 8 is arranged on the upper outer side of the EVA foam 7, an anti-stupid corner 9 is arranged at one corner of the blister tray body 1, waist-shaped holes 10 are arranged around the blister tray body 1, and limiting columns 11 are arranged in the middle of both sides of the blister tray body 1.

[0014] It is worth noting that the foamed silicone sleeve 4 is an injection-molded silicone sleeve.

[0015] It is worth noting that the blister tray body 1 is made of a PET tray.

[0016] In addition, a light-through hole 12 is provided at the center of the blister tray body 1 .

[0017] The blister tray of this specific embodiment is designed with a bare cell limit groove, and the bottom of the bare cell and the contact surface of the tray are covered with a relatively soft EVA foam pad to prevent the cell surface from being damaged due to inertial friction. The blister tray is provided with a stopper block, and the stopper is covered with a relatively soft foam silicone sleeve, which is cast by injection molding with uniform thickness, and its purpose is to prevent the cell from being damaged by side collision during the transportation of the cell; the tray at the bottom of the cell is provided with a long stopper, and the inner surface of the stopper is covered with a long strip of soft foam to prevent the bottom of the cell from being deformed by collision.

[0018] In this specific embodiment, the battery cell pole ear positions on both sides, that is, the shoulders of the battery cell, are designed with embedded EVA foam to prevent the battery cell from causing damage and deformation to the pole pieces and isolation membranes on the shoulders of the battery cell due to inertia. This position is relatively fragile and has high requirements, and the legs of the block cannot go too deep, otherwise interference will be caused by the misalignment of the pole ears.

[0019] The tray of this specific embodiment is made of PET material with relatively good toughness through the blister forming process, with high strength, good reliability and recyclable use; the tray is provided with anti-stupid corner, waist-shaped holes for bottom support connection, positioning pin holes (limiting columns) and QR code label positions, and the light-through hole is used to detect whether there are any missing batteries on the tray.

[0020] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
