Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a potting fixture, a potting device, and a battery production line. Background Technology

[0002] To improve the heat dissipation of the battery during operation, thermally conductive adhesive needs to be injected between the battery cell assembly and the casing. However, due to factors such as actual operating temperature rise, cost, and battery weight requirements, adhesive is usually not injected into all gaps between the cell assembly and the casing, but only between the two opposite sidewalls of the cell assembly and the casing.

[0003] In related technologies, automated dispensing machines are used to dispense adhesive into batteries. However, due to limitations in the cross-sectional area of ​​the internal flow channel structure and the fluidity of the thermally conductive adhesive, if the dispensing machine dispenses the required amount of adhesive at once, the thermally conductive adhesive will overflow into areas where it is not needed, failing to achieve the desired effect. Therefore, multiple dispensing cycles are required until the amount of adhesive inside the battery meets the design requirements.

[0004] However, this cyclical potting method results in a longer potting time for batteries, affecting the efficiency and capacity of the battery production line. Utility Model Content

[0005] In view of this, the present invention provides a potting fixture, a potting device, and a battery production line to solve or improve the problem that the cyclic potting method in related technologies affects the efficiency and capacity of the battery production line.

[0006] In a first aspect, this utility model provides a potting fixture for potting adhesive between a battery cell assembly and its casing, comprising:

[0007] The casing has an internal space for holding the glue.

[0009] The connecting structure is connected to the first accommodating space and the second accommodating space respectively, and is used to guide the glue in the first accommodating space to one side of the battery cell assembly between the battery cell assembly and the outer casing, and to guide the glue in the second accommodating space to the other side of the battery cell assembly between the battery cell assembly and the outer casing.

[0010] In one optional implementation, the connectivity structure includes:

[0011] A first connecting structure is connected to the housing, and one end of the first connecting structure is connected to the first receiving space, while the other end is used to extend into the gap between the housings on one side of the battery cell assembly.

[0012] The second connecting structure is connected to the housing, and one end of the second connecting structure is connected to the second receiving space, while the other end is used to extend into the gap between the other side of the cell assembly and the housing.

[0013] In one alternative implementation, at least one of the first connecting structure and the second connecting structure includes a discharge hopper;

[0014] The first end of the discharge hopper is connected to the housing and communicates with the first or second accommodating space. The second end of the discharge hopper is used to communicate with the gap between the housing and the battery cell assembly. The flow cross-sectional area of ​​the discharge hopper gradually decreases along the direction from the first end to the second end.

[0015] In one alternative implementation, at least one of the first connecting structure and the second connecting structure includes a first baffle and a second baffle.

[0016] The first baffle and the second baffle are both connected to the housing. The first baffle and the second baffle form a flow guiding structure that allows glue to flow. One end of the flow guiding structure is connected to the first accommodating space or the second accommodating space, and the other end is used to extend into the gap between the housing and the battery cell assembly. The first baffle is close to the battery cell assembly, and the second baffle is close to the housing.

[0017] In one optional embodiment, the first baffle includes a first plate body portion, a first folding portion, and a second plate body portion;

[0018] The first plate portion is connected to the shell, the first folding portion is connected to the end of the first plate portion away from the shell and folds toward the second baffle, and the second plate portion is connected to the end of the first folding portion away from the first plate portion and extends away from the shell.

[0019] And / or, the second baffle includes a third plate portion, a second folding portion, and a fourth plate portion;

[0020] The third plate portion is connected to the housing, the second folding portion is connected to the end of the third plate portion away from the housing and folds towards the direction of the first baffle, and the fourth plate portion is connected to the end of the second folding portion away from the third plate portion and extends away from the housing.

[0021] And / or, along the flow direction of the connecting structure, the distance between the end of the first baffle away from the housing and the housing is greater than the distance between the end of the second baffle away from the housing and the housing.

[0022] In one optional embodiment, there is a gap between the first connecting structure and the second connecting structure, so that an installation space is formed between the first connecting structure and the second connecting structure;

[0029] Furthermore, the first and second accommodating spaces can correspond to the two sides of the battery cell assembly, respectively.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] The following is combined Figures 1 to 8 The following describes the glue-pouring fixture 100 provided in the embodiments of this utility model.

[0044] Specifically, the potting fixture 100 is used to pot adhesive between the battery cell assembly 200 and the housing 300. It can be understood that the battery cell assembly 200 is disposed inside the housing 300. The potting fixture 100 includes a housing 1, a separator 2, and a connecting structure.

[0045] The housing 1 has an internal receiving space 101 for holding the adhesive. The adhesive includes, but is not limited to, thermally conductive adhesive.

[0046] The separator 2 is disposed in the receiving space 101 and is connected to the housing 1, that is, the separator 2 is connected to the inner wall of the housing 1. Optionally, the separator 2 is configured as a partition plate. The separator 2 divides the receiving space 101 into a first receiving space 1011 and a second receiving space 1012. The first receiving space 1011 and the second receiving space 1012 are independent of each other, and both the first receiving space 1011 and the second receiving space 1012 can contain glue.

[0047] The connecting structure is connected to the first receiving space 1011 and the second receiving space 1012 respectively, and is used to guide the glue in the first receiving space 1011 to one side of the cell assembly 200 and the outer shell 300, and to guide the glue in the second receiving space 1012 to the other side of the cell assembly 200 and the outer shell 300.

[0048] In this embodiment, when using the potting fixture 100, a preset weight or preset volume of glue is poured into the first receiving space 1011 and the second receiving space 1012 respectively. The glue in the first receiving space 1011 is injected into the gap between one side of the battery cell assembly 200 and the outer shell 300 through the connecting structure, and the glue in the second receiving space 1012 is injected into the gap between the other side of the battery cell assembly and the outer shell 300 through the connecting structure.

[0049] With this configuration, by providing a receiving space 101 inside the housing 1 to accommodate adhesive, for example, the adhesive required for the battery can be poured into the receiving space 101 at the same time. During the process of the adhesive flowing into the battery, this time can be used to continue pouring adhesive into the potting fixture 100 of other batteries, reducing the number of times the battery is potted, thereby improving the efficiency of potting.

[0050] Furthermore, since glue needs to be injected on both sides of the battery cell assembly 200, in order to avoid the glue in the accommodating space 101 not being accurately distributed on both sides of the battery cell assembly 200, resulting in poor accuracy of glue injection on both sides of the battery cell assembly 200, in this embodiment, the accommodating space 101 is divided into a first accommodating space 1011 and a second accommodating space 1012 by the separator 2.

[0051] Specifically, the first receiving space 1011 and the second receiving space 1012 can correspond to the two sides of the battery cell assembly 200, respectively. Thus, according to the glue filling requirements on both sides of the battery cell assembly 200, the corresponding volume or weight of glue can be poured into the first receiving space 1011 and the second receiving space 1012, respectively. Finally, the glue in the first receiving space 1011 is introduced to one side of the battery cell assembly 200 through the connecting structure, and the glue in the second receiving space 1012 is introduced to the other side of the battery cell assembly 200, so as to ensure that the glue filling amount on both sides of the battery cell assembly 200 can meet the requirements.

[0052] In some embodiments provided by this utility model, the connecting structure includes a first connecting structure 3 and a second connecting structure 4.

[0053] The first connecting structure 3 is connected to the housing 1, and one end of the first connecting structure 3 is connected to the first receiving space 1011. The other end of the first connecting structure 3 is used to extend into the gap between the side wall of the first side of the battery cell assembly 200 and the housing 300, so that the first connecting structure 3 can guide the glue in the first receiving space 1011 to the gap between the side wall of the first side of the battery cell assembly 200 and the housing 300.

[0054] The second connecting structure 4 is connected to the housing 1, and one end of the second connecting structure 4 is connected to the second receiving space 1012. The other end of the second connecting structure 4 is used to extend into the gap between the side wall of the second side of the battery cell assembly 200 and the housing 300, so that the second connecting structure 4 can guide the glue in the second receiving space 1012 to the gap between the side wall of the second side of the battery cell assembly 200 and the housing 300.

[0055] In this embodiment, when using the potting fixture 100, the first connecting structure 3 can be inserted into the gap between one side of the battery cell assembly 200 and the outer casing 300, and the second connecting structure 4 can be inserted into the gap between the other side of the battery cell assembly 200 and the outer casing 300.

[0056] Then, a preset weight or preset volume of glue is poured into the first receiving space 1011 and the second receiving space 1012 respectively. The glue in the first receiving space 1011 is injected into the gap between one side of the battery cell assembly 200 and the outer shell 300 through the first connecting structure 3, and the glue in the second receiving space 1012 is injected into the gap between the other side of the battery cell assembly 200 and the outer shell 300 through the second connecting structure 4.

[0057] With this configuration, by providing a receiving space 101 inside the housing 1 to accommodate adhesive, for example, the adhesive required for the battery can be poured into the receiving space 101 at the same time. During the process of the adhesive flowing into the battery, this time can be used to continue pouring adhesive into the potting fixture 100 of other batteries, reducing the number of times the battery is potted, thereby improving the efficiency of potting.

[0058] Furthermore, the first receiving space 1011 and the second receiving space 1012 can correspond to the two sides of the battery cell assembly 200, respectively. Thus, according to the glue filling requirements on both sides of the battery cell assembly 200, the corresponding volume or weight of glue can be poured into the first receiving space 1011 and the second receiving space 1012, respectively. Finally, the glue in the first receiving space 1011 is introduced to one side of the battery cell assembly 200 through the first connecting structure 3, and the glue in the second receiving space 1012 is introduced to the other side of the battery cell assembly 200 through the second connecting structure 4, so as to ensure that the glue filling amount on both sides of the battery cell assembly 200 can meet the requirements.

[0059] refer to Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the first connecting structure 3 and the second connecting structure 4 are located at the same end of the housing 1. For example, both the first connecting structure 3 and the second connecting structure 4 are located at the bottom end of the housing 1. A feeding port 102 is provided at the end of the housing 1 away from the first connecting structure 3 and the second connecting structure 4. For example, the feeding port 102 is located at the top end of the housing 1. The feeding port 102 is connected to the first receiving space 1011 and the second receiving space 1012, respectively.

[0060] In this embodiment, the feeding port 102 is located at the top of the housing 1, and the glue can fall naturally by gravity. By setting the first connecting structure 3 and the second connecting structure 4 at the bottom of the housing 1, the glue inside the first receiving space 1011 and the second receiving space 1012 can enter the first connecting structure 3 and the second connecting structure 4 respectively by gravity.

[0061] In some embodiments provided by this utility model, at least one of the first connecting structure 3 and the second connecting structure 4 includes a discharge hopper 301. (See reference) Figure 5The example shown is that both the first connecting structure 3 and the second connecting structure 4 include a discharge hopper 301. Of course, either one of them may be provided with a discharge hopper 301.

[0062] The first end of the discharge hopper 301 is connected to the housing 1, for example, the first end of the discharge hopper 301 is connected to the bottom end of the housing 1. The first end of the discharge hopper 301 communicates with either the first receiving space 1011 or the second receiving space 1012. The second end of the discharge hopper 301 communicates with the gap between the housing 300 and the battery cell assembly 200, so that the discharge hopper 301 can guide the glue in the first receiving space 1011 or the second receiving space 1012 into the gap between the housing 300 and the battery cell assembly 200.

[0063] Along the direction from the first end to the second end of the discharge hopper 301, the flow cross-sectional area of ​​the discharge hopper 301 gradually decreases. It can be understood that, as the name suggests, the discharge hopper 301 is used to guide the glue, and the discharge hopper 301 naturally has a flow guiding space for guiding the glue.

[0064] In this embodiment, when the adhesive passes through the gradually narrowing discharge hopper 301, the adhesive is subjected to gradually increasing pressure inside the discharge hopper 301, which makes it easier to overcome resistance or stickiness, ensuring that the adhesive remains continuous and stable during the dispensing process and reducing the possibility of blockage or interruption.

[0065] In addition, the gradually narrowing design of the discharge hopper 301 helps ensure that all the glue can be discharged from the discharge hopper 301, reducing the amount of glue residue and improving the accuracy of glue dispensing.

[0066] Optionally, the discharge hopper 301 is configured as a pyramidal structure, a frustum structure, a cone structure, or a frustum structure.

[0067] In some embodiments provided by this utility model, at least one of the first connecting structure 3 and the second connecting structure 4 includes a first baffle 3021 and a second baffle 3022. (See reference) Figures 2-5 The example shown is where both the first connecting structure 3 and the second connecting structure 4 include a first baffle 3021 and a second baffle 3022.

[0068] The first baffle 3021 and the second baffle 3022 are both connected to the housing 1, and the first baffle 3021 and the second baffle 3022 form a flow guiding structure 302 for the flow of adhesive. One end of the flow guiding structure 302 is connected to the first receiving space 1011 or the second receiving space 1012, and the other end is used to extend between the housing 300 and the battery cell assembly 200.

[0069] It is understood that the flow guiding structure 302 can be directly connected to the first receiving space 1011 or the second receiving space 1012, or it can be connected to the first receiving space 1011 or the second receiving space 1012 through the discharge hopper.

[0070] The first baffle 3021 is located near the cell assembly 200, and the second baffle 3022 is located near the housing 300. For example, see reference. Figure 2 and Figure 3 As shown, during the potting process, with the flow guiding structure 302 extending between the outer shell 300 and the cell assembly 200, in the horizontal direction, the first baffle 3021 faces the cell assembly 200, and the second baffle 3022 faces away from the cell assembly 200, or in other words, the second baffle 3022 faces the outer shell 300.

[0071] In this embodiment, by forming a flow guiding structure 302 with the first baffle 3021 and the second baffle 3022, it is convenient to adjust the distance between the first baffle 3021 and the second baffle 3022, and to make the distance between the first baffle 3021 and the second baffle 3022 smaller. By reducing the distance between the first baffle 3021 and the second baffle 3022, it is convenient to place the flow guiding structure 302 in the gap between the cell assembly 200 and the outer shell 300, thereby avoiding the problem that the gap between the cell assembly 200 and the outer shell 300 is too small, making it inconvenient to place the first connecting structure 3 or the second connecting structure 4.

[0072] In addition, the design of the first baffle 3021 facing the cell assembly 200 and the second baffle 3022 facing away from the cell assembly 200 ensures that the flow guiding structure 302 can be accurately inserted into the predetermined position between the cell assembly 200 and the housing 300, thereby helping to achieve more precise glue application and avoiding problems such as glue overflow or uneven distribution.

[0073] Optionally, both the first baffle 3021 and the second baffle 3022 are connected to the housing 1 via the discharge hopper 301. The first baffle 3021 and the second baffle 3022 are both connected to the second end of the discharge hopper 301, and the flow guiding structure 302 formed by the first baffle 3021 and the second baffle 3022 is in communication with the discharge hopper 301. This arrangement allows either the first connecting structure 3 or the second connecting structure 4 to possess the advantages of both the discharge hopper 301 and the first baffle 3021 and the second baffle 3022.

[0074] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, the first baffle 3021 includes a first plate body portion 3021a, a first folding portion 3021b, and a second plate body portion 3021c.

[0075] The first plate portion 3021a is connected to the housing 1. For example, the first plate portion 3021a is connected to the housing 1 through the discharge hopper 301, and the first plate portion 3021a is connected to the second end of the discharge hopper 301.

[0076] The first folding portion 3021b is connected to the end of the first plate portion 3021a that faces away from the housing 1, and folds towards the second baffle 3022. Alternatively, refer to Figure 2 and Figure 3 As shown, during the potting process, in the horizontal direction, the first folding part 3021b folds away from the cell assembly 200.

[0077] The second plate portion 3021c is connected to the end of the first folding portion 3021b that is away from the first plate portion 3021a and extends in a direction away from the housing 1. That is, the second plate portion 3021c is offset relative to the first plate portion 3021a in the direction of the second baffle 3022.

[0078] In this embodiment, the second plate portion 3021c is connected to the first plate portion 3021a via the first folding portion 3021b, thereby generating an offset in the horizontal direction relative to the first plate portion 3021a towards the direction where the second baffle 3022 is located.

[0079] Since the top of the battery cell assembly 200 has a circuit board 240, in this embodiment, when the first baffle 3021 extends between the battery cell assembly 200 and the outer casing 300, the offset of the second plate portion 3021c can create a clearance effect on the circuit board 240 of the battery cell assembly 200, and the blocking effect of the first baffle 3021 can prevent glue from being poured onto the circuit board 240.

[0080] In addition, the second plate portion 3021c is offset in the direction of the second baffle 3022, thereby reducing the flow cross-sectional area of ​​the flow guiding structure 302 to facilitate the adjustment of the flow rate of the glue.

[0081] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, the second baffle 3022 includes a third plate body portion 3022a, a second folding portion 3022b, and a fourth plate body portion 3022c.

[0082] The third plate portion 3022a is connected to the housing 1. For example, the third plate portion 3022a is connected to the housing 1 through the discharge hopper 301, and the third plate portion 3022a is connected to the second end of the discharge hopper 301.

[0083] The second folding portion 3022b is connected to the end of the third plate portion 3022a that faces away from the housing 1, and folds towards the first baffle 3021. Alternatively, refer to Figure 2 and Figure 3 As shown, during the potting process, the second folding part 3022b folds in the direction of the cell assembly 200 in the horizontal direction.

[0084] The fourth plate portion 3022c is connected to the end of the second folding portion 3022b that is away from the third plate portion 3022a and extends in a direction away from the housing 1. That is, the fourth plate portion 3022c is offset relative to the third plate portion 3022a in the direction of the first baffle 3021.

[0085] In this embodiment, the fourth plate portion 3022c is connected to the third plate portion 3022a via the second folding portion 3022b, thereby generating an offset in the horizontal direction relative to the third plate portion 3022a towards the direction where the second baffle 3022 is located.

[0086] refer to Figure 3 As shown, when the second baffle 3022 extends between the cell assembly 200 and the housing 300, the fourth plate portion 3022c can enter between the cell assembly 200 and the housing 300, thereby guiding the adhesive and preventing the adhesive from overflowing from the port of the housing 300.

[0087] The second folding portion 3022b can abut against the end of the outer shell 300, thereby providing a positioning effect for the glue-pouring fixture 100 and preventing the glue-pouring fixture 100 from being inserted too deeply or too shallowly. At the same time, the second folding portion 3022b abutting against the end of the outer shell 300 can provide support for the glue-pouring fixture 100 and improve the stability during the glue-pouring process.

[0088] In addition, the fourth plate 3022c is offset in the direction of the second baffle 3022, thereby reducing the flow cross-sectional area of ​​the flow guiding structure 302 to facilitate the adjustment of the flow rate of the glue.

[0089] Further, refer to Figure 3 As shown, in the height direction of the glue-pouring fixture 100, one end of the fourth plate portion 3022c, which is away from the second folded portion 3022b, is located above the first folded portion 3021b, and the dimensions of the fourth plate portion 3022c in the height direction of the glue-pouring fixture 100 can be adjusted as needed. For example, if the dimensions of the fourth plate portion 3022c are increased, the flow cross-sectional area of ​​the flow guiding structure 302 will decrease; if the dimensions of the fourth plate portion 3022c are decreased, the flow cross-sectional area of ​​the flow guiding structure 302 will increase.

[0090] refer to Figure 5 As shown, in some embodiments provided by this utility model, there is a gap between the first connecting structure 3 and the second connecting structure 4, so that an installation space is formed between the first connecting structure 3 and the second connecting structure 4.

[0091] The glue-dispensing fixture 100 also includes a first reinforcing plate 5, which is disposed in the mounting space between the first connecting structure 3 and the second connecting structure 4, and both ends of the first reinforcing plate 5 are connected to the first connecting structure 3 and the second connecting structure 4, respectively. For example, the first reinforcing plate 5 is disposed between the discharge hoppers 301 of the first connecting structure 3 and the second connecting structure 4, and is connected to both discharge hoppers 301.

[0092] In this embodiment, there is a gap between the first connecting structure 3 and the second connecting structure 4 so that the first connecting structure 3 and the second connecting structure 4 correspond to the two sides of the battery cell assembly 200, respectively. By connecting the first connecting structure 3 and the second connecting structure 4 with the first reinforcing plate 5, the overall rigidity of the potting fixture 100 can be improved, avoiding the problem of deformation or cracking of the potting fixture 100 due to excessive glue weight.

[0093] Optionally, the number of first reinforcing plates 5 is set to at least two, thereby further improving the overall rigidity of the glue-filling fixture 100.

[0094] In some embodiments provided by this utility model, the housing 1 is provided with at least two support plates 6. The first connecting structure 3 and the second connecting structure 4 are both connected to corresponding support plates 6, and the support plates 6 are used to abut against the end face of the housing 300.

[0095] In this embodiment, by setting the support plate 6 to abut against the end face of the outer shell 300, a positioning effect is achieved for the glue-pouring fixture 100, preventing the glue-pouring fixture 100 from being inserted too deeply or too shallowly. At the same time, the support plate 6 abutting against the end of the outer shell 300 can provide support for the glue-pouring fixture 100, improving the stability during the glue-pouring process.

[0096] It is understandable that the support plate 6 can be set as part of the housing 1 and used to enclose the receiving space or the discharge hopper 301. Of course, the support plate 6 can also be a part independent of the housing 1.

[0097] Optionally, refer to Figure 4 As shown, the surfaces of the support plate 6, the third plate body 3022a, and the side wall of the housing 1 are flush, for example, the three are configured as an injection-molded integral structure.

[0098] In some embodiments of this utility model, the glue-filling fixture 100 further includes a second reinforcing plate 7, which is connected to the first connecting structure 3, the second connecting structure 4, and the support plate 6. By connecting the first connecting structure 3, the second connecting structure 4, and the support plate 6 with the second reinforcing plate 7, the overall rigidity of the glue-filling fixture 100 can be improved, avoiding the problem of deformation or cracking of the glue-filling fixture 100 due to excessive glue weight.

[0099] In some embodiments provided by this utility model, the housing 1, the separator 2, the first connecting structure 3, the second connecting structure 4, the first reinforcing plate 5, the support plate 6, and the second reinforcing plate 7 are configured as an integral structure, for example, as an injection-molded integral structure.

[0100] Furthermore, both the first connecting structure 3 and the second connecting structure 4 include a discharge hopper 301, a first baffle 3021, and a second baffle 3022, and the connection form of the discharge hopper 301, the first baffle 3021, and the second baffle 3022 is as described above. The discharge hopper 301, the first baffle 3021, and the second baffle 3022 are configured as an integral structure, for example, as an injection-molded integral structure.

[0101] refer to Figure 7 As shown, in some embodiments provided by this utility model, the battery cell assembly 200 includes a battery cell 210, an insulating pad 220, and a spacer 230.

[0102] The number of insulating pads 220 is set to two, and the two insulating pads 220 are respectively disposed on the first side and the second side of the cell assembly 200.

[0103] There are multiple battery cells 210, which are arranged between two insulating pads 220. Each insulating pad 220 has two spacers 230 on the surface facing away from the battery cell 210, and the two spacers 230 are spaced apart.

[0104] In this embodiment, during the use of the potting fixture 100, the first connecting structure 3 or the second connecting structure 4 extends between the insulating pad 220 and the outer shell 300, and the first connecting structure 3 or the second connecting structure 4 is disposed between the two partitions 230.

[0105] By providing an insulating pad 220 between the housing 300 and the battery cell 210, the insulation performance between the housing 300 and the battery cell 210 can be improved. By providing two spacers 230 on the insulating pad 220, the adhesive can be confined between the insulating pad 220 and the housing 300, preventing the adhesive from flowing outside the area of ​​the insulating pad 220.

[0106] Furthermore, before placing the battery cell assembly 200 into the housing 300, a primer can be poured into the housing 300, and then the battery cell assembly 200 can be placed into the housing 300. The primer covers the lower end of the partition 230 and the lower end of the insulating pad 220, thereby sealing the lower end of the insulating pad 220 and preventing the adhesive from flowing outside the area of ​​the insulating pad 220.

[0107] Optionally, the partition 230 may include, but is not limited to, foam. The insulating pad 220 may be made of any insulating material.

[0108] refer to Figure 8As shown, in some embodiments provided by this utility model, the outer shell 300 includes a main body 310 and a cover plate 320.

[0109] The main body 310 is configured as a cylindrical structure, and a cover plate 320 is closed at the bottom end of the main body 310. For example, the cover plate 320 can be welded or screwed to the main body 310. A groove 330 is provided on the inner side wall of the main body 310, which can be used for the insertion of the first connecting structure 3 or the second connecting structure 4. Fins 340 are provided on the outer side wall of the main body 310 opposite to the groove 330, which can be used to improve the heat dissipation effect of the battery.

[0110] This utility model embodiment also provides a glue-dispensing device.

[0111] Specifically, the glue-dispensing apparatus includes a glue-dispensing machine and a glue-dispensing fixture 100 as described above.

[0112] It should be noted that the glue dispensing device includes the glue dispensing fixture 100, and thus includes all the advantages of the glue dispensing fixture 100 mentioned above.

[0113] This utility model also provides a battery production line.

[0114] Specifically, the battery production line includes the potting fixture 100 as described above or the potting device as described above.

[0115] It should be noted that the battery production line includes the potting fixture 100, and therefore includes all the advantages of the potting fixture 100 mentioned above.
