Abstract
Description
Technical Field
[0001] The utility model relates to a blister tray, in particular to a three-claw soft-connected blanking blister tray. Background Art
[0002] Bare cells are the main component of power batteries. The battery pack of power batteries is composed of multiple single cells connected in series and parallel. The cells are generally welded together through soft connections. The soft connection welding has high requirements. It is easy to have eccentricity during the welding process, resulting in poor welding and scrap. In order to prevent eccentricity loss of welding cells, a three-claw auxiliary positioning tray is designed to solve the above problem. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a three-jaw soft-connect blanking blister tray, which has a reasonable structural design, is easy and reliable to use, can prevent welding errors caused by shaking of the battery core, and is highly practical.
[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a three-jaw soft-connected blanking blister tray, including a blister tray body, a bottom support connecting hole, a main clamping jaw avoiding groove, an auxiliary clamping jaw avoiding groove, hollowing, a foamed silicone sleeve, EVA foam, a pole support column and a dual-cell welding limit groove, a plurality of bottom support connecting holes are arranged around the bottom of the blister tray body, a dual-cell welding limit groove is arranged on the blister tray body, a block is arranged at the bottom of the dual-cell welding limit groove, a foamed silicone sleeve is covered on the outside of the block, a main clamping jaw avoiding groove and an auxiliary clamping jaw avoiding groove are arranged on the outside of the dual-cell welding limit groove, a hollowing is arranged at the bottom of the main clamping jaw avoiding groove, a pole support column is arranged at the middle bottom of the dual-cell welding limit groove, and EVA foam is arranged at the bottom of the position where the dual cells are placed on both sides of the pole support column.
[0005] Preferably, the limit reserved gap between the stopper, the blister tray body and the bare battery cell is 1.2 mm.
[0006] Preferably, the EVA foam has a thickness of 4 mm.
[0007] The beneficial effects of the utility model: the utility model has a reasonable structural design, can well protect the dual battery cells, prevent the battery cells from shaking and causing welding errors, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;
[0009] Figure 1 It is a schematic diagram of the structure of the utility model;
[0010] Figure 2 It is a schematic diagram of the use 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-jaw soft-connected blanking blister tray, comprising a blister tray body 1, a bottom support connection hole 2, a main clamping jaw avoiding groove 3, an auxiliary clamping jaw avoiding groove 4, a hollow 5, a foamed silicone sleeve 6, an EVA foam 7, a pole support column 8 and a dual-cell welding limiting groove 9, a plurality of bottom support connection holes 2 are arranged around the bottom of the blister tray body 1, a dual-cell welding limiting groove 9 is arranged on the blister tray body 1, a stopper is arranged at the bottom of the dual-cell welding limiting groove 9, a foamed silicone sleeve 6 is covered on the outside of the stopper, a main clamping jaw avoiding groove 3 and an auxiliary clamping jaw avoiding groove 4 are arranged on the outside of the dual-cell welding limiting groove 9, a hollow 5 is arranged at the bottom of the main clamping jaw avoiding groove 3, a pole support column 8 is arranged at the middle bottom of the dual-cell welding limiting groove, and EVA foam 7 is arranged at the bottom of the position where the dual cells are placed on both sides of the pole support column 8.
[0013] It is worth noting that the limit reserved gap between the stopper, the blister tray body 1 and the bare battery cell 10 is 1.2 mm.
[0014] In addition, the EVA foam 7 has a thickness of 4 mm.
[0015] The soft connection welding tray (blister tray) of this specific embodiment is made of ABS+TPU material with good flexibility, high strength and durability through negative pressure blister process. The blister tray is provided with double battery core welding limit grooves, the side of the battery core is limited by the tray body, and a stopper is provided at the bottom. Since the diaphragm at the bottom of the bare battery core is easily deformed, a foamed silicone sleeve is provided on the stopper. The foamed silicone is soft in texture and has a hardness of Shorc 18. It has a good buffering effect and effectively prevents the deformation of the diaphragm at the bottom of the battery core.
[0016] In this specific embodiment, a 1.2mm gap is reserved between the bare battery cell and the block and the tray body to prevent welding errors caused by shaking of the battery cell. The tray is provided with double main jaws and a single auxiliary jaw limiting groove, which is convenient for the manipulator to grasp the battery cell in the same position every time. In order to prevent the main jaw from interfering with the tray, the bottom of the main jaw limiting groove is hollowed out. A pole support column is provided at the bottom of the soft connection avoidance position to prevent poor welding caused by the collapse of the soft connection during welding. A 4mm EVA foam pad is provided at the bottom of the battery cell to prevent poor appearance caused by friction of the battery cell.
[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.
