[0032] An embodiment of the present disclosure is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments may be combined with each other.

[0033] Figure 1 This is a diagram of the battery glue coating fixture 100 provided in this embodiment when in use. Figure 2 This is a schematic diagram of the structure of the battery 210 described in this embodiment. Figure 1 and Figure 2 This embodiment discloses a battery glue coating fixture 100, which is used to coat glue on the surface of a battery 210. It is understandable that the battery glue coating fixture 100 can be used to coat glue on two side surfaces 201 of a square lithium battery.

[0034] It is understandable that the square lithium battery has two side surfaces 201, and both side surfaces 201 need to be coated with glue to fix the battery 210, and then perform welding and other operations. The battery coating fixture 100 disclosed in this embodiment can conveniently control the width and thickness of the glue coating on the battery 210 to ensure uniformity.

[0035] The battery glue coating fixture 100 includes a stationary frame 110 and a glue coating plate 120. The stationary frame 110 has a receiving cavity 101 for receiving the battery 210. A glue coating window 102 is provided on one side of the stationary frame 110, and the glue coating window 102 is connected to the receiving cavity 101. The glue coating window 102 is used for the glue coating plate 120 to extend into and form a glue coating gap 103 with the battery 210 to evenly coat the glue.

[0036] Figure 3 A schematic diagram of the structure of the stationary rack 110 of the battery glue coating fixture 100 provided in this embodiment. The stationary rack 110 is used to place the battery 210 to facilitate the glue coating of the battery 210. In this embodiment, the stationary rack 110 includes a base 112 and two clamping plates 113 arranged on the base 112. The two clamping plates 113 are arranged opposite to each other, and a receiving cavity 101 is formed between the two clamping plates 113 and the base 112 to accommodate the battery 210. The base 112 is used to carry the battery 210, and the two clamping plates 113 are used to clamp the battery 210.

[0037] It is understandable that the battery 210 is placed from top to bottom in the accommodating cavity 101, at which time the bottom surface of the battery 210 can be placed on the base 112, and the two clamping plates 113 can clamp the two side surfaces 201 of the battery 210. It should be noted that the clamping here can have a certain gap.

[0038] As an embodiment, the base 112 and the clamping plate 113 are both plate-shaped to enclose a rectangular accommodating cavity 101. It is understood that the distance between the two clamping plates 113 is exactly equal to the length of the battery 210. It should be understood that the width of the clamping plate 113 can be set to the width of one battery 210 or the width of multiple batteries 210, so that multiple batteries 210 can be glued at the same time.

[0039] In this embodiment, the two clamping plates 113 are both provided with the glue application windows 102 , so that the glue application plate 120 can extend into any one of the glue application windows 102 to apply glue to the two side surfaces 201 of the battery 210 .

[0040] It should be understood that in an optional embodiment, the glue window 102 may be provided on only one of the clamping plates 113 .

[0041] To meet the structural requirements of square lithium batteries, in this embodiment, the cross section of the glue window 102 is rectangular. The glue window 102 has two oppositely disposed guide walls 104, which are used to guide the movement of the glue plate 120.

[0042] In order to limit the movement of the glue coating plate 120, in this embodiment, the glue coating window 102 also has two oppositely arranged limiting walls 105, and the two limiting walls 105 are respectively arranged at the two ends of any one of the guide walls 104. The limiting walls 105 are used to abut against the glue coating part 123 when the glue coating plate 120 slides to the extreme position.

[0043] It can be understood that the glue coating plate 120 extends into the glue coating window 102, and the two sides of the glue coating plate 120 can slide with the two guide walls 104 to provide guidance, and when the glue coating plate 120 slides to the end of the glue coating window 102 and cannot slide any further, the limiting wall 105 just contacts the glue coating plate 120 to prevent glue overflow.

[0044] As an implementation mode, in this embodiment, a clearance groove 106 is further opened on the surface of the static rack 110 . The clearance groove 106 is in a trapezoidal shape, and the small end of the clearance groove 106 is connected to the glue coating window 102 .

[0045] It can be understood that the inner walls of the clearance grooves 106 are inclined toward the outside of the glue coating window 102, which can facilitate the sliding operation of the glue coating plate 120.

[0046] In this embodiment, the stationary frame 110 further includes a stop plate 114 . The stop plate 114 is disposed on one side of the base 112 and is connected to the two clamping plates 113 . The stop plate 114 is used to fit the battery 210 .

[0047] In this embodiment, two stopper plates 114 are provided and spaced apart to be connected to the two clamping plates 113 respectively. It should be understood that the two stopper plates 114 are provided in the same plane. It can be understood that the gap formed between the two stopper plates 114 can facilitate the access to the battery 210.

[0048] In order to ensure that the side surface 201 of the battery 210 can be completely coated with glue and to reduce the waste of glue as much as possible, in this embodiment, the inner surface of the stop plate 114 and a side wall of the glue coating window 102 are arranged in the same plane.

[0049] It is understandable that this structure allows the side 201 of the battery 210 to be completely exposed in the width direction, and the gap between the side wall of the glue window 102 and the side 201 of the battery 210 is small, so that glue can be applied as much as possible and waste can be reduced.

[0050] It should be understood that in an optional embodiment, the shape and size of the accommodating cavity 101 should not be limited, and can be changed according to the structural shape of the battery 210. Similarly, the shape and size of the gluing window 102 should not be limited, and can be adaptively changed according to the gluing requirements of the battery 210.

[0051] Figure 4 This is a schematic diagram of the structure of the glue coating plate 120 of the battery glue coating fixture 100 provided in this embodiment. Figure 4 In this embodiment, the glue-coated plate 120 is in the shape of a plate as a whole, and includes a holding portion 121, a limiting portion 122 and a glue-coated portion 123. The limiting portion 122 is arranged at one end of the glue-coated portion 123, and the holding portion 121 is arranged on a side of the limiting portion 122 away from the glue-coated portion 123.

[0052] The width of the glue coating portion 123 is smaller than the width of the limiting portion 122. The two sides of the glue coating portion 123 form sliding grooves 107 with the ends of the limiting portion 122 respectively. The glue coating portion 123 extends into the glue coating window 102, and the bottom walls 108 of the two sliding grooves 107 are respectively slidably matched with the surface of the static frame 110.

[0053] It can be understood that the glue coating portion 123 itself has a certain height and can extend into the glue coating window 102. The bottom walls 108 of the two slide grooves 107 respectively slide with the surface of the static frame 110 to form a limit, while the side surfaces 109 of the two slide grooves 107 respectively slide with the two guide walls 104 to form a guide, thereby achieving high glue coating efficiency.

[0054] Furthermore, the glue coating parts 123 of different heights can be selected as needed to extend into the glue coating window 102 to different depths, and finally different glue coating gaps 103 are formed to apply glue of different thicknesses.

[0055] Similarly, the width of the glue window 102 and the width of the glue portion 123 can be designed to be different according to the size of the battery 210 to adjust the glue width.

[0056] In this embodiment, in order to ensure that the battery glue coating fixture 100 does not damage the surface of the battery 210, all materials of the battery glue coating fixture 100 are hard plastic, which has strong plasticity and will not scratch the battery 210 during glue coating. If different glue coating thicknesses are required for the same type of battery 210, it can also be achieved by replacing the glue coating plate 120, which has strong flexibility.

[0057] Figure 5 This is a diagram of the battery glue coating fixture 100 in use according to an optional embodiment of the present disclosure. Figure 5 It is understandable that, according to different gluing requirements, the battery gluing fixture 100 can also be configured to include only one clamping plate 113. And the battery gluing fixture 100 can just place a square lithium battery for gluing.

[0058] In other optional embodiments, the battery gluing fixture 100 can also be specifically configured with gluing windows 102 and gluing plates 120 of different shapes according to the shape of the battery 210 , for example, for cylindrical batteries 210 .

[0059] In summary, when the battery gluing fixture 100 disclosed in this embodiment is used, the battery 210 can be placed on the stationary rack 110 and accommodated in the accommodating chamber 101, so that the side wall of the battery 210 that needs to be glued is exposed from the gluing window 102. Then the gluing portion 123 of the gluing plate 120 is extended into the gluing window 102, so that the bottom wall 108 of the two slide grooves 107 of the gluing plate 120 slides with the surface of the stationary rack 110 respectively, and the stationary rack 110 limits the movement of the gluing plate 120 to form a stable stroke, so that the colloid is applied to a uniform thickness in the gluing gap 103 formed between the gluing portion 123 and the side wall of the battery 210. The battery gluing fixture 100 is not only simple in structure, low in cost and manufacturing price, but also can limit the thickness of the gluing of the battery 210, and is simple to operate and practical and convenient.

[0060] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
