In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] The following further describes the present utility model in conjunction with embodiments.

[0036] Embodiment:

[0037] This case proposes a battery restraint tray. Refer to the attached Figures 1-6 , which mainly includes a concave body 1. The body 1 consists of a bottom plate and vertical plates erected on both sides of the bottom plate. The body 1 is divided into four columns of restraint channels 10 along its width direction, and the restraint channels 10 are located between the two vertical plates.

[0038] In this case, along the length direction of the vertical plates, that is, the width direction of the body 1, four groups of sliding rods are equidistantly arranged between the two vertical plates. Each group of sliding rods includes two sliding rods arranged at intervals up and down, and the adjacent groups of sliding rods form a column of restraint channels 10.

[0039] A push plate 11 that can linearly move along the length direction of the body 1 is provided on the body 1. The push plate 11 is arranged along the width direction of the body 1. The push plate 11 is sleeved on two groups of sliding rods and can slide directionally on the sliding rods. And a plurality of laminates 2 for placing batteries are equidistantly arranged along the length direction of the body 1 in each column of restraint channels 10. The two sides of the plurality of laminates 2 are also sleeved on the adjacent sliding rods and slide, and the push plate 11 is fixed to two laminates 2 on the same side in two columns of restraint channels 10 and is used to drive the two laminates 2 to move simultaneously.

[0040] The battery is placed between two adjacent laminates 2. When the push plate 11 starts to move, it will drive the laminate 2 to start moving.

[0041] In this case, a slider 21 is respectively provided on both sides of each laminate 2. Hooks 22 and grooves 23 are respectively provided on both sides of the slider 21. The hook 22 cooperates with the groove 23 of the slider 21 on the adjacent laminate 2. The width of the groove 22 is greater than the width of the hook 21, and the laminate 2 is detachably connected to the sliders 21 on its two sides.

[0042] Specifically, a slot is opened in the slider 21 along its vertical direction, and a pin block that can be inserted into the slot is provided on the side end surface of the laminate 2. Thus, when the size of the battery to be processed changes, it can be achieved by replacing laminates 2 of different sizes.

[0043] In this case, the slider 21 slides on the sliding rod, and the adjacent sliders 21 on the same sliding rod move through the hook portion 22 and the groove portion 23. When it is necessary to increase the distance between the adjacent laminates 2, the push plate 11 is driven to pull the first laminate 2 toward the side of the push plate 11. As a result, the hook portion 22 on the side of the laminate 2 will pull the groove portion 23 on the adjacent slider 21. When reaching the maximum pulling position, there is a certain gap between the slider 21 and the groove portion 23 with which it cooperates.

[0044] At this time, the battery is placed between the two laminates 2 by means of a manipulator.

[0045] Similarly, when it is necessary to restrain the battery, the push plate 11 is driven to push the first laminate 2 toward the side away from the push plate 11. The gap between the slider 21 and the groove portion 23 with which it cooperates gradually decreases. When reaching the maximum pushing position, the two adjacent laminates 2 will fix the battery located between the two laminates 2.

[0046] In this case, the height of the laminate 2 is basically the same as the height of the battery. Therefore, in order to facilitate the removal of the battery between the two laminates 2 from the laminate 2 by means of a manipulator, in this case, the slot 12 is arranged in the middle of the restraint channel 10 and arranged along the length direction of the restraint channel 10, and the slot 12 is located directly below the battery in the restraint channel 10. When it is necessary to remove the battery, a certain lifting mechanism can be arranged at the position of the slot 12 to push out the battery directly above the slot 12, which is convenient for the manipulator to grasp. The manipulator and the lifting mechanism are well-known technologies and will not be elaborated here.

[0047] In this case, in order to prevent the battery from overheating during internal charging and affecting the quality of the battery, a card slot 24 for fixing the battery is respectively arranged on both sides of the laminate 2. The outer wall of the peripheral side of the card slot 24 is made of a hollowed-out treatment to improve the heat dissipation speed.

[0048] Furthermore, a layer of protrusions 25 are respectively arranged at one end of the laminate 2 facing the battery. The protrusions 25 are integrally in the shape of a convex platform. The protrusions 25 are located in the middle of the card slot 24 and are directly opposite to the position where the battery core is located. When the battery overheats, there is a certain gap between the battery core and the housing. When the battery is placed in the laminate 2 for charging, the protrusions 25 just abut against the position of the housing where the battery core is located, so as to prevent the battery from bulging.

[0049] And in order to further ensure that the distance between the laminates 2 will not change due to bulging, and indirectly contain the bulging phenomenon of the battery, in this case, a vertically liftable restraint insert block 3 is also arranged between the machine body 1 and the push plate 11. A grasping position 31 is arranged at the upper end of the restraint insert block 3. The linear lifting movement of the restraint insert block 3 can be realized by using a manipulator or other lifting mechanisms. The use of the driving mechanism is not limited here and is not shown in the figure either.

[0050] The difference is that a partition plate 101 is further provided between the body 1 and the push plate 11, and the distance between the partition plate 101 and the body 1 is greater than the thickness of the restraint insert 3. When the restraint insert 3 is removed from between the body 1 and the push plate 11, the restraint insert 3 can move to be stored between the body 1 and the partition plate 101, eliminating the need to set up an additional station to place the restraint insert 3 and reducing the volume of the station setup.

[0051] Meanwhile, in order to improve the smoothness of inserting the battery between the laminates, arc angle treatment is performed on both side edges at the upper end of the laminate 2 and located at the card slot 24.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
