Description

Technical Field

[0001] The utility model relates to a blister tray, in particular to a bare battery core X-RAY online detection blister tray. Background Art

[0002] After the bare battery cell is wound, it needs to be inspected by X-ray. Through X-ray irradiation, the layout of the positive electrode, negative electrode and isolation layer inside the battery cell can be seen, and whether there are foreign objects, hot spots and other problems can be detected to ensure that the internal structure of the battery cell is normal. The traditional inspection method is to complete the sampling inspection manually. The X-ray defect caused by the misalignment of the bare battery cell pole piece poses a major safety hazard. In order to reduce safety risks and ensure that each battery cell can be inspected, an online inspection tray is designed to improve inspection efficiency and reduce safety risks. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a bare battery cell X-RAY online detection blister tray, including a tray body, a protrusion, a bottom support connecting groove, a large rounded corner avoidance space, a stopper and a bare battery cell limiting groove, a bare battery cell limiting groove is arranged on the tray body, a bottom support connecting groove is arranged at the four corners of the tray body, a large rounded corner avoidance space is arranged at the four corners of the bare battery cell limiting groove, a stopper is arranged in the middle of the pole ear position of the bare battery cell limiting groove, and a protrusion for raising the bare battery cell is arranged in the middle position of the bare battery cell limiting groove.

[0005] Preferably, the gap between the bare cell limiting groove and the bare cell is 0.5 mm.

[0006] Preferably, the height of the protrusion is 3 mm.

[0007] Preferably, robot avoidance grooves are provided at both ends of the bare cell limiting groove.

[0008] Beneficial effects of the utility model: the structural design of the utility model is reasonable. The X-ray tray is made of PET material with a base material of 2.0 mm thickness through a blister forming process. The material has high impact resistance, good toughness and can be recycled. It can well protect the bare battery cells and is safe and reliable to use, thereby improving detection efficiency and reducing safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0011] Figure 2 It is a structural schematic diagram 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 bare cell X-RAY online detection blister tray, comprising a tray body 1, a protrusion 2, a bottom support connecting groove 3, a large rounded corner avoidance space 4, a stopper 5 and a bare cell limiting groove 6, a bare cell limiting groove 6 is arranged on the tray body 1, a bottom support connecting groove 3 is arranged at the four corners of the tray body 1, a large rounded corner avoidance space 4 is arranged at the four corners of the bare cell limiting groove 6, a stopper 5 is arranged in the middle of the pole ear position of the bare cell limiting groove 6, and a protrusion 2 for raising the bare cell is arranged in the middle position of the bare cell limiting groove 6.

[0014] It is worth noting that the gap between the bare cell limiting groove 6 and the bare cell 8 is 0.5 mm.

[0015] It is worth noting that the height of the protrusion 2 is 3 mm.

[0016] In addition, robot avoidance grooves 7 are provided at both ends of the bare cell limiting groove 6 .

[0017] In this specific embodiment, the tray is provided with a bare cell limit groove, and the gap between the limit groove and the bare cell is set to 0.5mm to prevent measurement deviation caused by inertial shaking on the line. The four corners of the limit between the tray and the bare cell adopt a large avoidance design to prevent the four corners of the cell from rubbing against the tray, causing problems such as decarbonization of the pole piece and powder loss of the isolation film. A block is provided in the middle of the pole ear to prevent the pole ear from misalignment and causing a short circuit in the cell. The limit block and the inner side of the limit groove are chamfered to prevent the cell from being damaged by rubbing against the edge of the tray when it is taken in and out. A 3mm high support surface is provided at the cell position of the tray to lift the cell to prevent the pole ear of the cell from colliding and deforming with the tray floor.

[0018] 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.
