[0002] Soft-pack lithium-ion batteries are liquid lithium-ion batteries covered with a polymer shell, and usually use aluminum-plastic composite film for battery cell packaging. In the event of a safety hazard, the soft-pack battery will only bulge and crack at most, but will not explode. When transporting, soft-pack lithium-ion batteries need to be placed in a tray for packaging. The tray in the prior art is a plastic part, and a groove for placing soft-pack lithium-ion batteries is provided in the tray. The groove is used to accommodate the soft-pack lithium-ion batteries and position the soft-pack lithium-ion batteries. In order to facilitate the loading and unloading of soft-pack batteries, a gap is provided between the soft-pack batteries and the groove wall. After the soft-pack batteries are loaded into the tray, they are easy to shake during the movement, and the soft-pack batteries are easy to detach from the tray; at the same time, in the existing tray, the bottom of the groove for loading the soft-pack lithium-ion batteries is flat, and when the soft-pack batteries are loaded, the flatness of the soft-pack batteries after loading into the tray is poor, so it needs to be improved.

DETAILED DESCRIPTION

[0014] The technical solution of the utility model is described clearly and completely below through embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 The illustrated embodiment is a wear-proof positioning and protection extraction tray for a soft-pack battery cell, which comprises an extraction tray body 1.

[0016] The extraction tray body 1 is an integral injection-molded or vacuum-molded part.

[0017] A plurality of receiving slots 2 for soft-pack battery cells are distributed on the extraction tray body 1. The number of receiving slots 2 can be set according to the size of the extraction tray and the size of the soft-pack battery. The receiving slots 2 are usually divided into several rows and columns and distributed on the extraction tray. For example, in the embodiment shown in the accompanying drawings, the receiving slots 2 on the extraction tray are divided into two rows and nine columns.

[0018] The middle portion of each receiving groove 2 is rectangular, and receiving portions for receiving the tabs 11 of the soft-pack battery cell are respectively arranged at the front and rear ends of the receiving groove 2 .

[0019] In order to prevent the bottom of the soft-packed battery cell 10 from being hit during transportation after the soft-packed battery cell 10 is loaded into the receiving groove 2, a first protrusion 3 is provided at the bottom of the receiving groove 2. The shape of the first protrusion 3 can be set as needed. In the embodiment shown in the drawings, the first protrusion 3 is a rectangular protrusion with a certain width. By setting the first protrusion 3 of this shape, the soft-packed battery cell 10 can be loaded more smoothly.

[0020] Positioning protrusions 4 for positioning the soft-pack battery cell are respectively provided on the left and right side walls of the accommodating groove 2. The number of the positioning protrusions 4 can be set as needed. In order to facilitate the removal of the soft-pack battery cell 10 from the accommodating groove 2, two positioning protrusions 4 can be set on the left and right side walls of the accommodating groove 2, and a removal gap is formed between the two positioning protrusions 4. The staff can quickly remove the soft-pack battery cell from the accommodating groove through the removal gap.

[0021] The shape of the positioning protrusion 4 can be set as required, for example, it can be set as a circular or rectangular protrusion.

[0022] Second protrusions 5 for supporting the tabs 11 of the battery cell are respectively provided in the front and rear directions of the receiving groove 2 . The second protrusions 5 are arranged at a position in the receiving groove 2 for accommodating the tabs 11 .

[0023] An anti-mistake convex rib 6 is provided between the second protrusion 5 and the first protrusion 3, and an arc-shaped positioning surface is provided on the top of the anti-mistake convex rib 6. By providing the anti-mistake convex rib 6 between the first protrusion 3 and the second protrusion 5, it is convenient to guide the loading position of the soft-pack battery cell 10 when loading the soft-pack battery cell 10, and the tab 11 can be quickly installed at the position of the second protrusion 5, thereby improving the efficiency of loading the soft-pack battery cell 10.

[0024] A limit baffle 7 is provided on one side of the second protrusion 5 to limit the front and rear directions of the battery cell. The height of the limit baffle 7 is adapted to the height of the soft-pack battery cell 10, and the limit baffle 7 extends to positions corresponding to the end surfaces of both ends of the soft-pack battery cell 10.

[0025] In order to indicate the loading direction of the soft-packed battery cell 10 when the soft-packed battery cell 10 is loaded into the receiving groove 2 , a positive electrode mark 8 and a negative electrode mark 9 for indicating the loading direction of the soft-packed battery cell are provided in the receiving groove 2 .

[0026] In order to facilitate the operator to quickly determine the positive and negative poles of the soft-pack battery cell 10 when taking out the soft-pack battery cell 10 from the receiving slot 2, a positive pole mark 8 and a negative pole mark 9 for indicating the loading direction of the soft-pack battery cell 10 are provided on the second protrusion 5.

[0027] The soft-pack battery cell anti-wear positioning protection extraction tray of the utility model should be used in conjunction with the extraction tray cover when in use. The extraction tray cover is connected to the extraction tray by positioning connectors such as buckles and connecting columns. When loading the soft-pack battery cell, first open the extraction tray cover, and then load the soft-pack battery cell into the receiving groove on the extraction tray in the direction of positive and negative poles. When loading the soft-pack battery cell, it can be manually operated or automatically loaded by a robot. When loading the soft-pack battery cell, it is only necessary to load the main body of the soft-pack battery cell into the area corresponding to the first protrusion in the receiving groove, and the pole ears at both ends of the soft-pack battery cell are loaded into the part that receives the pole ears, and the position of the anti-mistake convex rib is made to correspond to the main body of the soft-pack battery cell, so that the soft-pack battery cell The pole ear extends to the second protruding part through the anti-mistake convex rib. After the soft-pack battery cell is loaded into the receiving groove, the positioning protrusions on the two side walls of the receiving groove can press and position the two sides of the soft-pack battery cell to prevent the soft-pack battery cell from shaking left and right. The limiting baffle can limit the soft-pack battery cell in the front and back directions to prevent the soft-pack battery cell from escaping from the receiving groove in the front and back directions. After all the receiving grooves are filled with soft-pack battery cells, the extraction tray cover is covered on the extraction tray, and the extraction tray cover is fixedly connected to the extraction tray through connecting structures such as buckles and positioning columns.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
