Description

Technical Field

[0001] The invention relates to the technical field of batteries, and in particular to a battery restraint tray. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Lithium batteries have higher energy-to-weight ratio, energy-to-volume ratio, high rated voltage, low self-discharge and long-term storage, and high power bearing capacity. They are widely used in industries such as consumer electronics and electric vehicles. Among them, power lithium batteries are larger than ordinary lithium batteries and have more energy storage, requiring good packaging technology for storage and use. However, in the production environment of lithium batteries, their high energy ratio characteristics and the occurrence of thermal expansion inevitably expose the poor safety performance of lithium battery production. Therefore, there are strict requirements for the production and storage of lithium batteries. For example, in the processing of lithium battery formation and capacity separation, restraint trays are used to restrain lithium batteries.

[0003] The current restraint tray separates the batteries by multiple partitions. Before placing the batteries, the partitions are separated by a certain distance. After the batteries are placed between adjacent partitions, pressure is applied to bring the partitions closer together, thereby restraining the batteries. However, the applied pressure is usually large, for example, several tons of pressure is required. In order to reduce weight, the partitions are often made of plastic and other materials. Therefore, the partitions are often deformed due to excessive pressure, thereby crushing the batteries between the partitions. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 , which is a schematic structural diagram of a battery restraint tray and a battery according to an embodiment of the present invention. The battery restraint tray comprises: a base 10 and a restraint mechanism 20 arranged on the base 10.

[0034] See also Figure 2 , which is a schematic diagram of the structure of two adjacent partitions of an embodiment of the present invention, the restraint mechanism 20 includes a guide track 21 and a plurality of partitions 22, the guide track 21 is arranged on the base 10, the plurality of partitions 22 are movably connected to the guide track 21, the plurality of partitions 22 are arranged in sequence along the guide direction of the guide track 21, a restraint space 23 is formed between any two adjacent partitions 22, and a plurality of distance blocks 221 arranged around the partitions 22 are arranged on the partitions 22. When in use, the partitions 22 are first separated by a certain distance, and then the battery 30 is placed therein. When restraining the battery 30, the partition 22 is pushed along the guide track 21, the distance blocks 221 of any two adjacent partitions 22 abut against each other, and the adjacent partitions 22 restrain the battery 30 located between the partitions 22, and when releasing the restraint on the battery 30, the partitions 22 are separated from each other. A large pressure is applied to the partition 22, and the distance block 221 plays the role of supporting the structure of the partition 22, bearing the pressure applied to the partition, so that the partition 22 will not be deformed due to being crushed by the pressure, and a stable distance can be maintained between the partitions 22, thereby avoiding damage to the batteries between the partitions 22. The distance block 221 can be made of a material with sufficient hardness and strength, such as a distance block 221 made of steel. It should be noted that since the front side of the partition 22 located at the front is not required to form the restraint space 23, the shape and structure of the partition 22 located at the front can be adaptively adjusted, so its shape and structure can be different from the shape and structure of other partitions 22, so as to facilitate being pushed or fixed, and the structure of the rearmost partition 22 is the same.

[0035] See also Figure 3 and 4 , which are respectively a schematic diagram of the structure of a battery restraint tray according to an embodiment of the present invention and Figure 3As shown in the enlarged view of point A, in order to facilitate the fixing of the frontmost partition 22 and the rearmost partition 22 in the guide direction of the guide track 21, so that the partitions 22 are fixed to each other to restrain the battery 30, in some optional embodiments, the restraint mechanism 20 also includes a pressing plate 24, and the pressing plate 24 is arranged on the partition 22; a front end plate 11 and a rear end plate 12 are arranged on the base 10, and the guide track 21 is arranged between the front end plate 11 and the rear end plate 12, extending in the direction from the front end plate 11 to the rear end plate 12, and a plurality of partitions 22 are arranged between the front end plate 11 and the rear end plate 12, and the pressing plate 24 is arranged on the partition 22 closest to the front end plate 11, The partitions 22 are brought closer to each other by pushing the pressure plate 24, while the rear plate 12 presses against the partition 22 at the rear, which limits the partition 22. The front plate 11 is provided with a locking screw and a through hole 111 for the pressing mechanism to pass through. The locking screw is threadedly connected to the front plate 11. When the pressing mechanism pushes the partition 22 to the position to restrain the battery 30, the locking screw is rotated and pressed against the pressure plate 24 through the end of the locking screw. The pressure plate 24 presses the partition 22 against the rear plate 12, thereby fixing the position between the partitions 22. When the battery 30 is released from restraint, the pressure plate 24 is pulled away from the rear plate 12 to separate the partitions 22. Of course, according to actual needs, the pressure plate 24 may not be provided and the partition 22 at the front may be directly pushed, and then the partition 22 at the rear may be fixed to the base 10 through a threaded connector, a latch or other limiting structure. This example is not limited to this.

[0036] In addition, the pressing plate 24 and the rear end plate 12 are both made of materials with sufficient hardness and strength, and can withstand greater pressure without deformation.

[0037] In addition, in order to facilitate pulling the partition 22 away from the rear end plate 12, a pull-matching portion 25 is provided on the frontmost partition 22. In this embodiment, the pull-matching portion 25 is provided on the side of the pressing plate 24 away from the partition 22, and the pull-matching portion 25 is a hook, which can be hooked with the hook by a manipulator, and then the pressing plate 24 is pulled and moved by the manipulator. The clamping mechanism can use a telescopic mechanism such as a cylinder, an electric cylinder or a hydraulic cylinder to push the pressing plate 24 to move, and the through hole 111 facilitates the output shaft of the clamping mechanism to press against the pressing plate 24.

[0038] In addition, in the present embodiment, protection plates 13 are further provided on both sides of the base 10 , and both ends of the protection plates 13 are connected to the front end plate 11 and the rear end plate 12 .

[0039] See also Figure 5, which is an exploded view of two adjacent partitions of an embodiment of the present invention. Since the size of the battery 30 may be different, in order to adapt to the size of different batteries 30, it is necessary to replace the partitions 22 of different sizes. In some optional embodiments, the distance block 221 is detachably connected to the partition 22. Without changing the distance block 221, different partitions 22 are replaced to adjust the size and shape of the restraint space 23, thereby constraining different batteries 30. Of course, it is also possible to choose to replace different distance blocks 221 to adjust the distance between adjacent partitions 22 in the guide direction of the guide track 21, thereby adjusting the size of the restraint space 23.

[0040] The detachable manner of the distance block 221 and the partition 22 can be appropriately designed according to actual needs. In this embodiment, the partition 22 is provided with a plurality of mounting holes 222, the mounting holes 222 extend along the guide direction of the guide rail 21, and the distance block 221 is columnar and inserted into the mounting holes 222. Of course, the distance block 221 can also be fixed to the partition 22 by a threaded connector, a latch or a snap-on structure, for example, a snap-on slot is provided on the partition 22, and the distance block 221 is snapped into the snap-on slot, but this example is not limited thereto.

[0041] The locking screw needs to be twisted to the correct position by a torque wrench to ensure that the pressure of the locking screw on the pressure plate 24 is within an appropriate range, and the pressure plate 24 is tightened without over-pressing the pressure plate 24. When the locking screw is rotated, the friction between the end of the locking screw and the pressure plate 24 will cause the pressure plate 24 to be worn, and then the force applied by the locking screw to the pressure plate 24 is unstable. Therefore, in some optional embodiments, a thrust bearing 26 is provided on the side of the pressure plate 24 away from the partition 22. The thrust bearing 26 includes a shaft ring, a seat ring, and a rolling element connected between the shaft ring and the seat ring. The shaft ring and the seat ring can rotate with each other. The shaft ring of the thrust bearing 26 is connected to the locking screw, and the seat ring of the thrust bearing 26 is fixedly connected to the pressure plate 24. The locking screw applies pressure to the pressure plate 24 through the thrust bearing 26. When the locking screw rotates, the shaft ring rotates relative to the seat ring, and the seat ring is fixed, thereby avoiding wear of the pressure plate 24.

[0042] In order to facilitate the movement of each partition 22, in some optional embodiments, pull blocks 223 are provided on both sides of the partition 22; any two adjacent pull blocks 223 are connected by a number of limiting structures; wherein the limiting structure includes a limiting groove 224 and a limiting block 225, in any two adjacent pull blocks 223, the limiting groove 224 is provided on one of the pull blocks 223, the limiting block 225 is provided on the other pull block 223, the limiting groove 224 extends along the guide direction of the guide rail 21, the limiting block 225 extends into the limiting groove 224, the spacing range between the pull blocks 223 is limited by the limiting structure, when the pressure plate 24 pushes the partition 22 to move toward the rear end plate 12, the limiting block 225 on the pull block 223 located at the front moves along the limiting groove 224 to the limiting groove 224. The rear end of the pull block 223 is then driven to move in sequence, and the pull block 223 drives the movement of the partition 22 until all the spacing blocks 221 of the partitions 22 abut against each other. When the pressure plate 24 pulls the partition 22 toward the front end plate 11, the limit block 225 on the frontmost pull block 223 moves along the limit groove 224 to the front end of the limit groove 224, and then drives the rear pull block 223 to move in sequence, and the pull block 223 drives the movement of the partition 22 until all the partitions 22 are separated from each other to a predetermined distance, thereby releasing the restraint on the battery 30. The distance block 221 can be set on the partition 22 and / or the pulling block 223. For example, the distance block 221 is set on both the partition 22 and the pulling block 223. When the restraint of the battery 30 is completed, the distance block 221 of the pulling block 223 correspondingly abuts against the distance block 221 of the adjacent pulling block 223, and the distance block 221 on the partition 22 abuts against the distance block 221 of the adjacent partition 22; or, the distance block 221 is only set on the pulling block 223, and the above-mentioned mounting hole 222 is set on the pulling block 223, so that the distance block 221 and the pulling block 223 can be detachably connected.

[0043] The setting positions of the limiting grooves 224 and the limiting blocks 225 of the limiting structure can be appropriately designed according to actual needs. In this embodiment, four limiting structures are arranged between two adjacent pull blocks 223, wherein two limiting grooves 224 and two limiting blocks 225 are arranged on the rear side of the pull block 223 located at the front, two limiting grooves 224 and two limiting blocks 225 are arranged on the front side of the pull block 223 located between the pull block 223 at the front and the pull block 223 at the rear, two limiting grooves 224 and two limiting blocks 225 are arranged on the rear side, and two limiting grooves 224 and two limiting blocks 225 are arranged on the front side of the pull block 223 located at the rear, and the limiting blocks 225 are arranged at the ends of the limiting grooves 224 in a one-to-one correspondence, and together with the limiting grooves 224, form a hook-shaped structure. The pull block 223 can also be divided into a first pull block 223 and a second pull block 223, the first pull block 223 and the second pull block 223 are arranged at intervals along the guide direction of the guide track 21, the first pull block 223 is only provided with a limit groove 224, and the second pull block 223 is only provided with a limit block 225. Of course, those skilled in the art can also select other suitable arrangements according to the teachings of the present invention, which will not be described in detail here.

[0044] In addition, it should be noted that since the front side of the pull block 223 located at the front does not need to be connected to other pull blocks 223, in order to facilitate the pushing of the pressure block, the front side of the pull block 223 located at the front is fixedly connected to the pressure plate 24, and its shape structure can be adaptively adjusted. Therefore, the front side shape structure of the pull block 223 located at the front can be designed to be different from the shape structure of other pull blocks 223; similarly, the rearmost pull block 223 is fixedly connected to the rear plate 12, and its structure can be designed to be different from the structure of other pull blocks 223.

[0045] In order to facilitate production and assembly, to facilitate replacement of components when damaged rather than scrapping the entire assembly, and to facilitate quick replacement of the partition 22 when the size of the restraint space 23 needs to be adjusted, in some optional embodiments, the pull block 223 is detachably connected to the side of the partition 22 through a buckle 226. In this embodiment, a protruding buckle 226 is provided on the side of the partition 22, and a buckle groove is provided on the side of the pull block 223, and the elastic buckle 226 extends into the buckle groove, so as to limit the partition 22 and the pull block 223 in the vertical direction, and limit the horizontal direction by clamping the partition 22 between the guide rods 211.

[0046] See also Figure 6 and 7 , which are respectively an exploded view of a battery restraint tray according to an embodiment of the present invention when a portion of the protective plate is hidden and Figure 6As shown in the enlarged view of B, in some optional embodiments, the guide track 21 includes at least two guide rods 211, and the partition 22 is located between the at least two guide rods 211; a plurality of grooves 2231 are provided on the side of the pull block 223 away from the partition 22, and the grooves 2231 of adjacent pull blocks 223 are connected one by one, and all the grooves 2231 located on the same side of the partition 22 form a plurality of guide grooves after being connected, and the guide rods 211 extend into the guide grooves one by one. In this embodiment, the restraint mechanism 20 includes 4 guide rods 211, and the two ends of the guide rods 211 are fixedly connected to the front plate 11 and the rear plate 12 respectively, and the 4 guide rods 211 are evenly arranged on both sides of the partition 22, and two grooves 2231 are provided on one side of the pull block 223 away from the partition 22, and the grooves 2231 of the pull block 223 are connected one by one to form two guide grooves, and the guide rods 211 extend into the guide grooves accordingly, so as to facilitate the movement of the pull block 223 and the guide groove. Of course, the connection method between the guide rod 211 and the partition 22 is not limited to this, and those skilled in the art can also select other suitable structures according to the teachings of the present invention, such as setting a guide hole on the pull block 223, and the guide rod 211 sequentially passes through the guide hole of the pull block 223, so as to realize the movable connection between the pull block 223 and the guide rod 211. In addition, it should be noted that the structure of the guide rail 21 is not limited to this, and the structure of the guide rail 21 can be selected according to actual needs. For example, the guide rail 21 can adopt a guide structure such as a convex rail or a slide groove, and the pull block 223 or the partition 22 is movably assembled with the convex rail or the slide groove.

[0047] In order to facilitate the disassembly and assembly of the partition 22 and the pull block 223, in some optional embodiments, the limiting groove 224 of the pull block 223 is formed with a side opening 2241 on the side of the pull block 223 close to the partition 22. Taking the removal of the partition 22 and the pull block 223 as an example, since the partition 22 and the pull block 223 are detachably connected, the partition 22 and the pull block 223 can be separated first, and then the partition 22 is pulled out of the base 10, and then the pull block 223 is moved toward each other, so that the limiting block 225 is separated from the limiting groove 224 from the side opening 2241, and the guide rail 21 is separated from the groove 2231 of the pull block 223, and then the pull block 223 can be removed.

[0048] In order to increase the number of batteries 30 that can be placed, in some optional embodiments, at least two restraint mechanisms 20 are provided on the base 10 , and the at least two restraint mechanisms 20 are arranged in sequence along a direction perpendicular to the guide direction of the guide track 21 .

[0049] In order to support the bottom of the battery 30 and reduce the friction when the battery 30 moves, in some optional embodiments, the restraint mechanism 20 further includes a plurality of support plates 27, which are arranged one by one between adjacent partitions 22, and the support plates 27 are located at the bottom of the restraint space 23 and are movably connected to the guide track 21.
