Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, specifically to an airbag restraint tray. Background Technology

[0002] The formation of lithium batteries is an essential step in lithium battery processing. During the formation process, multiple lithium batteries are usually placed in a restraint tray. However, in the existing lithium-ion batteries, after being powered on during the formation process, the water molecules inside the battery are decomposed, producing hydrogen and oxygen, which can easily cause the battery to bulge, thus affecting the production quality of the battery.

[0003] In the prior art, such as the Chinese utility model patent with publication number CN218101481U entitled "Battery Restraint Tray," a specific disclosure includes a tray body, a restraint unit, and a positioning unit. The tray body is used to support the battery. The restraint unit includes multiple restraint portions spaced apart on the tray body, and a receiving cavity for accommodating the battery is formed between any two adjacent restraint portions. Furthermore, at least two adjacent restraint portions have their opposite sides configured as arc surfaces with a central bulge. The positioning unit is located on the tray body and can be manipulated to abut against the outermost restraint portion, thereby clamping the battery with the restraint unit.

[0004] The battery restraint tray in the above solution constructs two opposite sides of at least two adjacent restraint parts into arc surfaces with a raised center. This allows the two restraint parts to apply a larger restraint force to the center of the battery located between them, thereby improving the uniformity of the restraint force on various parts of the battery and effectively preventing the battery from bulging during precharging.

[0005] However, when the battery is placed between the two restraint parts in the above scheme, the presence of the arc surface can easily hinder the smooth insertion of the battery, affecting the overall process efficiency. In addition, even if a relatively gentle arc surface is used to limit the deformation and expansion of the battery side, when the battery has some minor deformation, the arc surface cannot effectively fit the battery side surface, and thus the restraint effect on the battery side is relatively weak.

[0006] Therefore, an airbag restraint tray is proposed to solve the problems mentioned above. Utility Model Content

[0007] Technical problems to be solved

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an airbag restraint tray, which can effectively solve the problem that the restraint effect of the battery tray in the existing technology is limited in the case of battery bulging.

[0009] Technical solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] This utility model provides an airbag restraint tray, including a tray body, which is a rectangular frame and has several shelves spaced apart along its length. The gaps between adjacent shelves are used to place batteries. The shelves are detachably connected to the tray body, and each shelf has a breathing plate that can move outwards simultaneously on both sides.

[0012] Furthermore, the breathing plate is guided and slidably mounted on the shelf; wherein, the shelf is provided with a magnetic component that magnetically attracts the breathing plate.

[0013] Furthermore, an inflatable air bladder is provided in the middle of the layer, and two breathing plates on each layer are symmetrically distributed on both sides of the air bladder.

[0014] Furthermore, it also includes an air collection valve, and several of the airbags are connected to the air collection valve via air tubes.

[0015] Furthermore, several of the tracheae are of the same length.

[0016] Furthermore, two battery holders are detachably provided on each of the two end faces of the shelf, and the two battery holders on the same end face are symmetrically distributed at the lower end of the breathing plate.

[0017] Furthermore, the upper end of the battery holder has a notch, and the breathing plate is located between two notches on the same side.

[0018] Furthermore, the upper end of each missing corner is chamfered or rounded.

[0019] Furthermore, several slots are longitudinally formed on opposite surfaces within the tray body, with the slots on each surface spaced apart and the width of the slots matching the thickness of the shelf side.

[0020] Furthermore, both sides of the upper end of the slot are chamfered or rounded.

[0021] Beneficial effects

[0022] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0023] This invention provides breather plates that can move outward simultaneously on both sides of each layer plate. This ensures that the breather plates do not obstruct the normal insertion of the battery when it is placed. During the battery formation process, the distance between the breather plates and the side surfaces of the battery can be flexibly adjusted to ensure that the breather plates are in close contact with the side surfaces of the battery, providing a good restraint effect.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example:

[0038] This case proposes an airbag restraint tray, see attached document. Figure 1-6 An airbag restraint tray includes a tray body 1, which is a rectangular frame. The implementation principle of the tray body 1 is a known technology, and its auxiliary structures are not described in detail.

[0039] The tray body 1 has several shelves 2 spaced apart along its length. The gaps between adjacent shelves 2 are used to place batteries. The number of shelves 2 can be adjusted according to actual needs.

[0040] Sheet 2 is detachably connected to tray body 1. Specifically, several slots 11 are longitudinally provided on opposite surfaces inside tray body 1. The slots 11 on each surface are spaced apart and the width of the slots 11 is adapted to the thickness of the side of the shelf 2.

[0041] In this embodiment, the shelf 2 can be inserted downwards along the slot 11 by a robotic arm or manually. To facilitate the insertion of the shelf 2, the upper sides of the slot 11 are chamfered or rounded. Even if there is a small deviation during insertion, the presence of the arc / sloping surface at the upper end of the slot 11 ensures that the shelf 2 can be smoothly inserted into the slot 11.

[0042] It should be noted that a number of push holes 12 are provided at intervals at the lower end of the tray body 1. The push holes 12 are located between adjacent shelves 2. After the battery has completed formation, the formed battery can be pushed away from the adjacent shelves 2 by an electric drive mechanism that can move vertically upward in the push holes 12.

[0043] It is worth noting that in this embodiment, each of the two end faces of each shelf 2 is provided with a breathing plate 21 that can move outward simultaneously, and the breathing plate 21 is guided and slidably installed in the middle position of the shelf 2.

[0044] Specifically, the two end faces of the shelf 2 are respectively provided with a middle groove for the shelf 21 to move inside, and a guide groove 23 is provided on both sides of the middle groove. The two sides of the breathing plate 21 are respectively provided with a lug 211, and the lug 211 slides within the guide groove 23.

[0045] The shelf 2 is provided with a magnetic component 20 that is magnetically attracted to the breathing plate 21. The magnetic component 20 is located in the guide groove 23 facing the lug 211 on the breathing plate 21. The magnetic component 20 and the lug 211 are magnetically attracted to each other. When the breathing plate 21 is in the initial position, the magnetic component 20 and the lug 211 are magnetically attracted together. When the breathing plate 21 is moved outward under the action of an external force, the magnetic component 20 and the lug 211 are disengaged and there is a certain rebound potential energy between them. When the force that drives the breathing plate 21 to move disappears, the breathing plate 21 returns to the initial position under the action of the rebound potential energy.

[0046] In this embodiment, an inflatable airbag 3 is provided in the middle of the layer 2. Two breathing plates 21 on each layer 2 are symmetrically distributed on both sides of the airbag 3. When the airbag 3 inflates, it applies a "push" to the breathing plates 21 on both sides, causing the lugs 211 on both sides of the breathing plates 21 to slide in the guide groove 23. When the airbag 3 contracts, it no longer applies force to the breathing plates 21, so that the breathing plates 21 return to their initial position under the action of rebound potential energy.

[0047] The method of setting the magnetic component 20 is not specifically limited, as shown in the attached figure. Figure 5 As shown, magnetic stickers / coatings can be provided on the guide groove 23 or the lug 211 to allow the two to magnetically engage;

[0048] As attached Figure 6 As shown, a guide post can also be provided on the guide groove 23, and a magnetic ring (i.e., magnetic component 20) can be sleeved on the guide post, with the magnetic ring and the lug 211 magnetically engaged.

[0049] There are several ways to magnetically engage two surfaces, which are well-known technologies. Here, only two methods are presented without further explanation.

[0050] It is worth noting that an air collecting valve 4 is also provided on the tray body 1. Several airbags 3 are connected to the air collecting valve 4 through the air pipe 31 connected to the bottom of the airbags 3. The air collecting valve 4 provides a unified air source to allow the airbags 3 to inflate simultaneously.

[0051] The length of the air tube 31 between the several airbags 3 and the air collecting valve 4 is the same, that is, the time and amount of gas from the air collecting valve 4 to the airbag 3 are the same, which can ensure that the several airbags 3 inflate at the same time and with equal expansion.

[0052] In addition, a vacuum generator (not shown in the figure) is connected to the tray body 1. The vacuum generator can be connected to the gas collection valve 4 through a pipe, which can quickly remove the gas in several air bags 3 by vacuum adsorption, so as to realize the rapid degassing of the air bags 3. There are many ways to degas the air bags 3, and they are known technologies. They will not be described in detail here, and they are not shown in the figure.

[0053] Two battery support blocks 22 are detachably provided on each of the two end faces of the shelf 2. The two battery support blocks 22 on the same side end face are symmetrically distributed at the lower end of the breathing plate 21. The four battery support blocks 22 between the connected shelf 2 are used to support the battery to be formed. The battery support blocks 22 are detachably connected to the side end face of the shelf 2 by screws, so that the size of the battery support blocks 22 can be adjusted according to the size of the battery to be formed. In order to limit the left and right displacement of the battery, a notch 221 is opened at the upper end of the battery support block 22. The breathing plate 21 is located between the two notches 221 on the same side. When the battery to be formed is placed above the four notches 221, a limit is formed on the four corners of the battery to prevent the battery from shifting and affecting the subsequent battery grasping operation.

[0054] To improve the smoothness of battery insertion, the upper end of the notch 221 is chamfered or rounded.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
