Description

Technical Field

[0001] The utility model generally relates to the technical field of lithium batteries, and more specifically relates to a blade battery baking fixture. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and non-aqueous electrolyte solutions. They have the advantages of high energy density, long cycle life and low self-discharge rate. Domestic lithium battery technology is mainly used in the new energy vehicle industry and energy storage industry.

[0003] According to the classification of power lithium batteries, traditional lithium batteries include cylindrical batteries, soft-pack batteries, and square batteries. With the continuous development of lithium battery technology, new forms of batteries have also emerged in recent years, such as blade batteries. Blade batteries are shaped like long blades in terms of volume, so they are called blade batteries. The height of blade batteries is generally 12cm, the width is in the range of 13-40cm, and the length can reach 600cm to 900cm. Its internal structure is stacked. When grouping, it can skip the module and directly integrate the battery cells into a battery pack, which greatly improves the volume utilization rate and the energy density of the battery, making it easier to accommodate more battery cells in the same space, thereby improving the battery life, and thus having the same performance as the ternary lithium battery with high energy density.

[0004] In view of the "blade" shape of blade batteries, traditional contact baking fixtures cannot bake blade batteries well. For example, after placing the batteries to be baked between adjacent heating plates of the contact baking fixture, it is necessary to use the connecting parts to slide along the guide rod to make the heating plates fixed to the connecting parts slide and contact with the batteries. However, due to the long strip shape of the blade battery, the structure of the traditional contact baking fixture is that the heating plate and the battery gradually approach and contact and squeeze each other, which can easily cause the heating plate to deform, thereby affecting the contact area between the heating plate and the battery, resulting in the failure to achieve the purpose of contact heating and baking that the contact fixture should have; at the same time, due to the large space occupied by the long strip structure of the blade battery, the traditional contact fixture needs to place the battery into the clamping position first and then clamp the battery, and the locking mechanism also occupies a large part of the space, resulting in a reduction in the number of blade batteries that can be held by a fixture of a certain volume; in addition, when baking blade batteries of different specifications, it is cumbersome to change the fixture, which affects production efficiency.

[0005] In view of this, it is urgent to provide a clamp specifically used for baking blade batteries to solve the problem. Utility Model Content

[0024] Embodiments will now be described with reference to the accompanying drawings. It should be understood that for simplicity and clarity of explanation, reference numerals may be repeated in the accompanying drawings to indicate corresponding or similar elements where deemed appropriate. In addition, the utility model sets forth many specific details in order to provide a thorough understanding of the embodiments described herein. However, it will be appreciated by those of ordinary skill in the art that the embodiments described herein may be practiced without these specific details. In other cases, well-known methods, processes, and components are not described in detail to avoid obscuring the embodiments described herein. Moreover, the description should not be construed as limiting the scope of the embodiments described herein.

[0025] According to one embodiment of the utility model, a blade battery baking fixture is provided, comprising: a base plate 1, a heating plate 2 is laid on the upper surface of the base plate 1, parallel and spaced fixing strips 3 are provided above the base plate 1, each fixing strip 3 has a plurality of vertical slots arranged at equal intervals on the left and right sides, a plurality of fins 4 are provided between each two adjacent fixing strips 3, the fins 4 are heat conducting strips, both ends of each fin 4 are respectively located in the vertical slots of two adjacent fixing strips 3, each fin 4 is in contact with the heating plate 2 for heat conduction, any two fins 4 are parallel to each other, and the shortest distance between two adjacent fins 4 is slightly larger than the thickness of the blade battery 100, and also comprises side panels 5 arranged around the base plate 1, and the inner side surfaces of the side panels 5 are mirror surfaces.

[0026] Here, the heating plate 2 may be an aluminum plate, which is laid on the bottom plate 1 , and the heating plate 2 is fixed on the bottom plate 1 by a fixing strip 3 .

[0027] Vertical slots are provided on the fixing strip 3, which can be set according to the specifications of the blade battery 100 to be baked (here referring to its width or thickness). For example, if the thickness of the blade battery 100 is 15 cm, the intervals between the vertical slots can be slightly larger than 15 cm. In this way, when the fin 4 is inserted into the vertical slot, the shortest distance between two adjacent fins 4 is slightly larger than 15 cm.

[0028] The side panels 5 and the bottom panel 1 can be fixed by fixing an L-shaped bracket on the bottom panel 1 and then fixing the side panels 5 and the L-shaped bracket to fix the side panels 5 and the bottom panel 1 .

[0029] The inner side surface of the side plate 5 is a mirror surface with high smoothness, which can continuously reflect the heat generated inside the clamp to the inside of the clamp, thereby improving the baking effect.

[0030] In order to meet the baking needs of blade batteries 100 of different specifications, the fixing strip 3 is detachably connected to the base plate 1, that is, the fixing strip 3 with vertical slots of different spacings is replaced according to the specifications of the blade batteries 100 to be baked. The connection between the fixing strip 3 and the base plate 1 can be bolted.

[0031] In one embodiment, a pressure strip 6 is further provided above the fixing strip 3, and the pressure strip 6 has a slot corresponding to the vertical slot of the fixing strip 3, and the slot is used to accommodate the end of the fin 4 to further fix the fin 4, so that the fin 4 is more stable when erected vertically.

[0032] In one embodiment, the pressure strip 6 is detachably connected to the fixing strip 3 . Similarly, after the fixing strip 3 is bolted to the bottom plate 1 , the pressure strip 6 can be bolted to the fixing strip 3 .

[0033] In another embodiment, an escape position is provided above each fin 4, and the escape position is used to avoid the clamping claw when the clamping claw clamps the blade battery 100, so as to facilitate the clamping claw to clamp the blade battery 100. It is easy to understand that the escape position here can be a notch, and when the clamping claw is in the process of placing or removing the blade battery 100, the notch can prevent the clamping claw from interfering with the fin 4.

[0034] In yet another embodiment, the thickness of the fin 4 is in the range of 2 to 4 mm.

[0035] Since the present solution adopts non-contact baking, the fins here are heat conductive fins, so the material of the fins 4 can be a material with good thermal conductivity, such as aluminum.

[0036] In order to achieve heating, the clamp further comprises a wiring board, on which are arranged wiring terminals connected to the heating plate 2, and the wiring terminals are used to connect to an external power source.

[0037] In order to control the baking temperature of the fixture, a control module is also included, and the control module is electrically connected to the heating plate 2 to control its temperature.
