[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0036] Packaging is one of the key processes of batteries. The packaging effect and efficiency have a great impact on battery production. With the increase in battery types, the size and structure of the battery tabs have great differences. During packaging, the existing packaging devices have poor compatibility, and customized heads are required for packaging of different types of batteries. The packaging efficiency is low, and customized heads are technically difficult and costly.
[0037] Reference below Figure 1-Figure 3 A packaging assembly according to an embodiment of the present invention is described.
[0038] According to the utility model, the packaging assembly 1 includes a first head 11, a second head 12 and a limit member 13. The first head 11 and the second head 12 can be selectively moved toward each other to encapsulate the battery; the limit member 13 is arranged on the first head 11, and a limit groove 130 for limiting the battery ear is formed on the limit member 13. The position of the limit member 13 relative to the first head 11 is adjustable to adjust the width of the limit groove 130 and / or adjust the relative position of the limit member 13 and the first head 11.
[0039] According to the packaging assembly 1 of the utility model, a first sealing head 11 and a second sealing head 12 are provided. The first sealing head 11 and the second sealing head 12 are spaced apart to reserve a space for packaging the battery. When the battery is placed between the first sealing head 11 and the second sealing head 12 and can be packaged, the second sealing head 12 moves toward the first sealing head 11 until the packaging of the battery is completed. In this process, it should be noted that a heating device needs to be provided on the first sealing head 11 and the second sealing head 12, or the first sealing head 11 and the second sealing head 12 need to have a heating function. When the temperature of the first sealing head 11 and the second sealing head 12 reaches a preset value, the second sealing head 12 can move toward the first sealing head 11. The setting of the heating function on the first sealing head 11 and the second sealing head 12 enables the first sealing head 11 and the second sealing head 12 to have the ability to package batteries.
[0040] A limiting member 13 can also be provided on the first head 11, and a limiting groove 130 for limiting the battery ear is formed on the limiting member 13. When the battery is placed between the first head 11 and the second head 12, the battery ear falls into the limiting groove 130. The limiting groove 130 can accommodate the battery ear and limit the shaking of the battery by limiting the battery ear, which can improve the packaging accuracy during the battery packaging process, avoid packaging errors that require repackaging or cause battery damage, and improve the packaging effect and packaging efficiency.
[0041] In addition, the position of the limiter 13 relative to the first end cap 11 is adjustable, which can also be understood as the limiter 13 can be moved on the first end cap 11 to adjust the width of the limiter groove 130 and the relative position of the limiter groove 130 and the first end cap 11. Specifically, the limiter 13 can be moved on the first end cap 11 and adjust the width of the limiter groove 130 so that the limiter groove 130 can adapt to battery tabs of various sizes. The limiter 13 can be moved on the first end cap 11 and adjust the relative position of the limiter groove 130 and the first end cap 11 so that the limiter groove 130 can adapt to batteries with different tab positions. The setting of the adjustable position of the limiter 13 relative to the first end cap 11 enables the packaging assembly 1 to adapt to batteries of different models and sizes, improves the compatibility of the packaging assembly 1, and can effectively reduce the cost of customizing the end cap in the prior art.
[0042] According to one embodiment of the utility model, the second head 12 and the first head 11 are at least partially opposite to each other in the direction of relative movement, and the second head 12 is provided with an avoidance hole 121 suitable for cooperating with the limiter 13. The size design of the avoidance hole 121 mainly depends on the size of the pole ear and the packaging size requirements. At the same time, the distance between the avoidance holes 121 can be equidistant or unequally spaced, that is, it needs to be confirmed by the width of the positioning groove 130 and the limiter 13. Specifically, the second head 12 is at least partially opposite to the first head 11 in the direction of movement toward the first head 11. During packaging, the packaging effect of the battery can be improved, and the problems of incomplete packaging and poor packaging effect caused by the misalignment of the first head 11 and the second head 12 can be avoided. In addition, an avoidance hole is also provided on the second head 12. Since the second head 12 needs to move toward the first head 11 and contact the first head 11 to achieve battery packaging during packaging, an avoidance hole 121 is provided on the second head 12 so that the second head 12 can avoid the limit member 13 when moving toward the first head 11. It can also be understood that at least part of the limit member 13 can pass through the avoidance hole 121, thereby avoiding the influence of the limit member 13 on the packaging.
[0043] According to an embodiment of the utility model, the avoidance holes 121 are configured as a plurality of avoidance holes 121 arranged at intervals in the extension direction of the first end cap 11, and the stopper 13 can selectively cooperate with one of the avoidance holes 121. Specifically, the avoidance holes 121 can be configured as a plurality of avoidance holes 121. After the stopper 13 moves to a different position or the stopper 13 changes the width of the limit groove 130 by movement, the stopper 13 can face different avoidance holes 121 in the direction in which the second end cap 12 moves toward the first end cap 11. The provision of a plurality of avoidance holes 121 avoids the influence of the movement of the stopper 13 on the packaging process.
[0044] According to one embodiment of the utility model, the limit member 13 includes a first limit member 131 and a second limit member 132, and the first limit member 131 and the second limit member 132 are spaced apart to define a limit groove 130. The first limit member 131 and the second limit member 132 are respectively movably connected to the first head 11 to adjust the width of the limit groove 130, and the first limit member 131 and the second limit member 132 can be selectively matched with a corresponding avoidance hole 121.
[0045] Specifically, the packaging assembly 1 is provided with a first stopper 131 and a second stopper 132, which are arranged at intervals in the extension direction of the first end cap 11 to define a stopper groove 130, wherein the width of the stopper groove 130, i.e., the distance between the first stopper 131 and the second stopper 132, can be precisely controlled according to the size of the battery cell tab through the first end cap scale line 111 on the first end cap 11. When the battery is assembled, the battery tab falls into the stopper groove 130, and the first stopper 131 and the second stopper 132 can adjust the width of the stopper groove 130 by moving toward or away from each other to limit the battery tab, thereby ensuring the accuracy of battery packaging. The provision of the first stopper 131 and the second stopper 132 enables the packaging assembly 1 to adjust the width of the stopper groove 130 or the position of the stopper groove 130 according to the battery model to be packaged and the size of the battery tab, so that the packaging assembly 1 can adapt to multiple types of batteries, thereby improving the compatibility of the packaging assembly 1.
[0046] According to an embodiment of the utility model, a sliding part is provided on the limiter 13, and a sliding matching part is provided on the first head 11, and the sliding part and the sliding matching part are slidably matched. The packaging component 1 is provided with a sliding part on the limiter 13 and a sliding matching part matching with the sliding part is provided on the first head 11. When the battery is placed between the first head 11 and the second head 12, the first limiter 131 and the second limiter 132 can respectively slide and match with the sliding matching part on the first head 11 through the corresponding sliding parts, and the width of the limiter groove 130 or the position of the limiter groove 130 can be adjusted by sliding in the extension direction of the first head 11. The setting of the sliding part and the sliding matching part can increase the adjustment rate of the limiter groove 130 and ensure the stability of the limiter 13 during the adjustment of the limiter groove 130, thereby improving the packaging efficiency of the packaging component 1.
[0047] According to an embodiment of the utility model, the packaging assembly 1 further includes a fastener 14, which is disposed on the limiter 13 and can selectively fix the limiter 13 to the first head 11 to limit the movement of the limiter 13. Since the limiter 13 can move on the first head 11, the packaging assembly 1 is further provided with a fastener 14 on the limiter 13, and the fastener 14 can fasten the limiter 13 to the first head 11 to limit the movement of the limiter 13 after the limiter 13 is adjusted, so as to prevent the limiter 13 from sliding after the battery is assembled, resulting in the limiter groove 130 being unable to limit the battery pole ear, thereby ensuring the stability of the battery during the packaging process.
[0048] According to an embodiment of the utility model, a base 151 is provided on the side of the first end cap 11 facing away from the second end cap 12, a support rod 152 is provided between the base 151 and the first end cap 11, and an installation gap for assembling the fastener 14 is formed between the first end cap 11 and the base 151. Specifically, the packaging assembly 1 is also provided with a base 151, and a support rod 152 is provided on the base 151. The free end of the support rod 152 can be connected to the first end cap 11 to support the first end cap 11. The provision of the support rod 152 allows an installation gap to be reserved between the first end cap 11 and the base 151. The installation gap can facilitate the adjustment of the fastener 14 and the stopper 13, and avoid the stopper 13 or the fastener 14 from being disturbed during use. The base 151 can improve the stability of the overall structure of the packaging assembly 1.
[0049] According to an embodiment of the utility model, the first sealing head 11 is provided with scale marks arranged at intervals in the moving direction of the limiter 13. The packaging component 1 can also be provided with scale marks on the first sealing head 11, and the scale marks can be provided in the moving direction of the limiter 13. When assembling the battery, the packaging component 1 can fasten the limiter 13 to the corresponding scale mark through the fastener 14 to improve the accuracy of the limiter 13 when adjusting. The scale marks can improve the efficiency of the packaging component 1 in adjusting the limit groove 130, thereby improving the packaging efficiency.
[0050] According to an embodiment of the utility model, the avoidance hole 121 is constructed as a long hole extending in the extension direction of the first head 11, and the limiter 13 can be selectively accommodated in any position in the long hole. Different from the multiple avoidance holes 121 in the above embodiment, the avoidance hole 121 on the second head 12 can be constructed as a long hole, and the long hole extends in the extension direction of the second head 12. At this time, no matter how the limiter 13 moves, it can be directly opposite to at least part of the long hole in the direction of the second head 12 moving toward the first head 11, that is, after adjusting the position of the limiter 13, it can still pass through the long hole during packaging. Compared with multiple avoidance holes 121, the long hole is easier to process.
[0051] According to one embodiment of the utility model, the packaging assembly 1 also includes a driving device 16, on which a driving rod 161 is movably provided, and the free end of the driving rod 161 is connected to the second head 12. The driving device 16 can selectively drive the driving rod 161 to drive the second head 12 to move.
[0052] Since the second end cap 12 needs to move toward the first end cap 11, a driving device 16 is provided on the side of the second end cap 12 away from the first end cap 11, and a driving rod 161 is provided on the driving device 16. The driving rod 161 can be telescopically moved, and the free end of the driving rod 161 is connected to the second end cap 12. During packaging, the driving device 16 can drive the driving rod 161 to drive the second end cap 12 to move toward the first end cap 11 to complete the packaging. After the packaging is completed, the driving device 16 can drive the driving rod 161 to drive the second end cap 12 away from the first end cap 11 to facilitate the removal of the battery. The provision of the driving device 16 improves the convenience of the packaging component 1 when in use.
[0053] According to an embodiment of the utility model, the packaging assembly 1 further includes: a buffer 162, which is sleeved on the outer circumference of the driving rod 161. When the driving device 16 is working, the buffer 162 can buffer the movement of the driving rod 161, so that the driving rod 161 can smoothly drive the second head 12 to move, making the packaging more uniform and improving the packaging effect.
[0054] According to an embodiment of the present invention, the packaging assembly 1 further includes a protective shell 17, and a receiving cavity suitable for receiving the first head 11 and the second head 12 is formed in the protective shell 17. During actual processing, the packaging assembly 1 can also be provided with a protective shell 17, and a receiving cavity is formed in the protective shell 17. The first head 11, the second head 12, the stopper 13, the fastener 14, the support rod 152 and the base 151 in the above embodiment can all be received in the receiving cavity. The protective shell 17 can prevent the external environment from interfering with the battery packaging and improve the packaging effect.
[0055] In some embodiments, a base 181 may be further provided at the bottom of the protective housing 17 , and the base 181 is connected to the floor via a plurality of support columns 182 , thereby improving the stability of the packaging assembly 1 .
[0056] In some embodiments, Figure 1 As shown, the limiter 13, the second head 12 and the drive device 16 can be constructed as a one-to-one correspondence. For example, two groups of second heads 12, two groups of limiters 13 and two groups of drive devices 16 can be arranged in the protective shell. The two groups of second heads 12 can independently package the positive and negative pole ears of the battery through independent drive devices 16, which is mainly used in situations where the ear size is small or the positive and negative pole ears have a large difference in size, and can provide comprehensive packaging needs.
