Description

Technical Field

[0001] The utility model relates to a blister tray, in particular to a three-claw cold-pressed blister tray. Background Art

[0002] After the bare cells of the power battery are wound, they must be cold pressed to finalize their shape, because the bare cells are in a fluffy state after winding. If the bare cells are not cold pressed, the arc at the edges will be too large, which will easily affect the energy density of the battery. Since the four corners of the bare cells are very fragile after cold pressing, decarbonization and breakage may easily occur during online assembly, which may result in the scrapping of the cells. Therefore, the utility model designs a double-jaw cold-pressed blister tray, which can effectively protect the bare cells while efficiently conveying and assembling them. Utility Model Content

The PET tray body is provided with a connected battery cell limit block, and a bare battery cell is placed on the battery cell limit block through an EVA foam pad. The PET tray body is provided with a transverse double-claw groove and a longitudinal auxiliary claw groove. The four corners of the battery cell limit block are provided with a foam silicone sleeve outside the avoidance position. The four sides of the PET tray body are provided with a plurality of waist-shaped holes that are convenient for connection with the bottom support of the conveyor line. The center of the PET tray body is provided with a light-through hole, one corner of the PET tray body is provided with an anti-stupid corner, and the limit pin is provided at the center of the four sides of the PET tray body.

[0005] Preferably, the center of the battery cell limiting block adopts a void-avoiding structure.

[0010] Figure 2It is a three-dimensional structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] 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.

[0012] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: a three-claw cold-pressed blister tray, comprising a PET tray body 1, a battery cell limiting block 2, a transverse double-claw groove 3, a longitudinal auxiliary claw groove 4, a waist-shaped hole 5, a limiting pin 6, a foamed silicone sleeve 7 and an anti-stupid corner 8. The PET tray body 1 is provided with a connected battery cell limiting block 2, and a bare battery cell 10 is placed on the battery cell limiting block 2 through an EVA foam pad 9. The PET tray body 1 is provided with a transverse double-claw groove 3 and a longitudinal auxiliary claw groove 4. The four corners of the battery cell limiting block 2 are provided with a foamed silicone sleeve 7. The four sides of the PET tray body 1 are provided with a plurality of waist-shaped holes 5 that are convenient for connecting with the bottom bracket of the conveyor line. The center of the PET tray body 1 is provided with a light-through hole 11, one corner of the PET tray body 1 is provided with an anti-stupid corner 8, and the limiting pin 6 is provided at the center of the four sides of the PET tray body 1.

[0013] It is worth noting that the center of the battery cell limiting block 2 adopts a void-avoiding structure.

[0014] In addition, the foamed silicone sleeve 7 is an injection-molded sleeve.

[0015] The blister tray of this specific embodiment is made of PET material with good toughness, high strength and durability. The blister tray is designed with battery cell limit blocks, which are designed as a one-piece block. The center of each limit block is designed to avoid airflow to protect the four corners of the battery cell from collision and decarbonization damage. Each one-piece limit block plays a limiting role in two directions. Since the battery cell is relatively large, the tray is provided with a horizontal double clamping groove and a vertical auxiliary clamping groove to ensure the balance of the battery cell grabbing.

[0016] The tray of this specific embodiment is provided with a waist-shaped hole for easy connection with the conveyor line base, a through hole for the light curtain sensor to sense the position of the tray, an anti-stale angle to ensure the consistency of the connection between the tray and the base, and four limit pins to ensure that the position of the tray is the same every time it is switched. The surface of the tray and the battery cell are in contact with a whole piece of foam to prevent the battery cell from rubbing against the tray and causing a poor appearance. The one-piece limit block of the tray is covered with a foam silicone sleeve, which is made by injection molding and has a soft texture, effectively protecting the battery cell from damage due to inertial collision.

[0017] 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.
