Description

Battery pressing device Technical Field

[0001] The present application relates to the technical field of battery assembly, and more specifically, to a battery press-assembly device. Background Art

[0002] In the production of blade batteries, press-fit pre-welding is a key step. After the battery is compacted using a press-fit pre-welding jig, a laser is used to pre-spot weld the blade battery's four edges while rotating it. The quality of press-fitting directly impacts the pre-spot welding process and the subsequent full weld yield, ultimately impacting the quality of the blade battery.

[0003] The current blade battery press head device is complex in structure. During press-fitting, the parallelism between the press head and the battery cover cannot be adjusted, and the battery cover and aluminum shell cannot be completely pressed together, failing to meet the required process parameters. Furthermore, the laser spot welding position is close to the press head, and the press head is often exposed to high temperatures and high dust. This results in the press head requiring regular maintenance and replacement after a period of use. The current complex press head structure is very inconvenient to maintain and replace, affecting the yield rate of blade batteries produced by the equipment, as well as reducing maintenance time and battery production efficiency.

[0031] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] The battery press-assembly device 100 according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0033] As shown in FIG1 to FIG4 , the battery press-fitting device 100 according to an embodiment of the present application is used to press-fit a battery 200 onto a fixture 300 . The battery press-fitting device 100 includes: a bottom plate 10 , a base 20 , a quick-release press head 30 and an adjustment assembly 40 .

[0034] Specifically, the base plate 10 is suitable for connecting with the jig 300, the base 20 is arranged on one side of the base plate 10, the quick-release press head 30 is detachably arranged on the base 20, and the side of the quick-release press head 30 away from the base plate 10 is provided with a pressing surface 31 suitable for pressing the battery 200, and the adjustment component 40 is connected to the quick-release press head 30 to adjust the parallelism of the pressing surface 31 and the battery 200.

[0035] In other words, the battery pressing device 100 according to the embodiment of the present application can be used to place the battery 200 on the jig 300, and the jig 300 can be a jig mechanism for press-fitting and pre-welding the battery 200, so that after the battery 200 is placed on the jig 300, the top cover of the battery 200 is pressed into place. The jig 300 can specifically include a rotating turntable, a driving mechanism, a welding mechanism, etc. The battery pressing device 100 is mainly composed of a base plate 10, a base 20, a quick-release press head 30 and an adjustment assembly 40, wherein the base plate 10 can be assembled on the outer side of the rotating turntable of the jig 300 through the assembly structure on both sides, thereby realizing the assembly of the battery pressing device 100 on the jig 300.

[0036] The base 20 is provided on the side of the bottom plate 10 facing the jig 300. The base 20 can be used to detachably assemble the quick-release press head 30, thereby improving the maintenance efficiency of the quick-release press head 30. The quick-release press head 30 is provided with a pressing surface 31 on the side facing the jig 300. The pressing surface 31 can be used to press the top cover of the battery 200 to achieve press-fitting of the battery 200. The adjustment component 40 is movably connected to the quick-release press head 30, and at least a portion of the adjustment component 40 can be moved to adjust the parallelism between the pressing surface 31 and the battery 200. By adjusting the parallelism between the pressing surface 31 and the battery 200, the effect of the battery press-fitting device 100 on the press-fitting of the battery 200 can be adjusted.

[0037] It should be noted that when the battery 200 is conveyed into the jig 300, the jig 300 can position the battery 200. Once the positioning is completed, the driving mechanism in the jig 300 can push the battery 200 to cooperate with the battery pressing device 100 for press-fitting. During press-fitting, the top cover of the battery 200 will abut against the pressing surface 31 of the quick-release pressing head 30. As the battery 200 continues to be pushed, the battery pressing device 100 can press-fit the battery 200.

[0038] Therefore, according to the battery pressing device 100 of the embodiment of the present application, by detachably connecting the quick-release pressing head 30 to the base 20, the quick-release pressing head 30 can be quickly replaced, reducing maintenance time and improving production efficiency; the adjustment component 40 can adjust the parallelism of the pressing surface 31 and the battery 200, thereby improving the pressing effect on the battery 200.

[0039] According to one embodiment of the present application, a mounting groove extending along a first direction is provided on a side of the base 20 away from the bottom plate 10 , and the quick-release press head 30 is detachably provided in the mounting groove.

[0040] Specifically, as shown in FIG4 , the first direction may be the direction in which the battery 200 is movable relative to the battery pressing device 100 . A mounting groove is provided on the base 20 , which enables the quick-release pressing head 30 to be assembled with the base 20 . The assembly structure is simple and feasible, and the assembly is convenient.

[0041] In some specific embodiments of the present application, the base 20 is provided with a limiting hole 22 connected to the installation groove at at least one end in the second direction, and a limiting member is provided in the limiting hole 22, which is movable to fix or release the quick-release pressure head 30.

[0042] Optionally, in the second direction, positioning holes 32 are respectively provided at both ends of the quick-release pressing head 30 , and limiting holes 22 are respectively provided at both ends of the base 20 . The limiting members in each limiting hole 22 are respectively movably provided in the positioning holes 32 .

[0043] In other words, as shown in FIG4 , the second direction can be perpendicular to the first direction, and the base 20 is provided with limiting holes 22 at both ends of the second direction, and the quick-release pressing head 30 is provided with positioning holes 32 at both ends of the second direction. The movable limiting member in the limiting hole 22 can be inserted into the positioning hole 32 or withdrawn from the positioning hole 32. The limiting member can be a top screw structure provided in the limiting hole 22, and the quick-release pressing head 30 can be detachably connected to the base 20 through the limiting hole 22. When the limiting member is inserted into the positioning hole 32, the quick-release pressing head 30 can be fixed, thereby achieving rapid assembly of the quick-release pressing head 30 on the base 20; when the limiting member is withdrawn from the positioning hole 32, the assembly of the quick-release pressing head 30 and the base 20 can be released, thereby achieving rapid disassembly of the quick-release pressing head 30.

[0044] Therefore, through this assembly structure, the quick-release pressure head 30 and the base 20 can be quickly disassembled and assembled, which effectively improves the replacement and maintenance efficiency of the quick-release pressure head 30, thereby improving the production efficiency of the battery 200.

[0045] According to an embodiment of the present application, each positioning hole 32 is respectively provided with a locking surface 321 extending obliquely relative to the second direction, and one end of the limiting member is detachably abutted against the locking surface 321 .

[0046] Specifically, as shown in FIG4 , the shape of the positioning hole 32 can be a hole-shaped structure corresponding to the shape of the end of the stopper. The positioning hole 32 can also have one side wall surface set as an inclined structure, namely a locking surface 321. The inclined surface structure of the locking surface 321 can cooperate with the stopper. The stoppers at both ends of the quick-release press head 30 press the locking surface 321 of the quick-release press head 30, thereby locking the quick-release press head 30. When the quick-release press head 30 needs to be replaced, it is only necessary to loosen the stoppers at both ends to quickly pull out the quick-release press head 30, and then quickly install a new quick-release press head 30.

[0047] In some specific embodiments of the present application, the bottom plate 10 is provided with a through hole 11 extending along the first direction, the base 20 is provided with an adjustment hole 24 extending along the first direction and connected to the mounting groove, and the adjustment component 40 includes: an adjustment top screw, the adjustment top screw is provided in the adjustment hole 24, and the adjustment top screw is movable to adjust the parallelism of the press-fit surface 31 and the battery 200.

[0048] As shown in Figure 4, in this embodiment, a through hole 11 structure that can be connected to the adjustment hole 24 on the base 20 is provided on the bottom plate 10, and an adjustment screw is provided in the adjustment hole 24. One end of the adjustment screw passes through the adjustment hole 24 and is connected to the quick-release pressure head 30. The adjustment screw is movable along a first direction, so that the position of the quick-release pressure head 30 can be adjusted, and then the parallelism of the pressing surface 31 relative to the battery 200 can be adjusted.

[0049] Therefore, the position of the adjusting screw can be adjusted through the through hole 11 provided on the bottom plate 10, thereby adjusting the quick release press head 30 to achieve adjustment of the press-fitting effect of the battery 200. The structural design is reasonable and the adjustment is convenient.

[0050] Optionally, according to some embodiments of the present application, the adjustment assembly 40 further includes: a plurality of pressure columns 42 and a plurality of adjustment members 43 .

[0051] Specifically, each pressure column 42 is respectively extended along the first direction and is arranged on the base 20, the first end of the pressure column 42 is connected to the base 20, the second end of the pressure column 42 is close to the pressing surface 31, at least one pressure column 42 is movable along the first direction, and each adjustment member 43 is respectively connected to the corresponding pressure column 42 to adjust the pressure column 42.

[0052] In some specific embodiments of the present application, the press-fitting surface 31 is rectangular, and there are four press pillars 42 , each of which is located at a vertex corner of the press-fitting surface 31 .

[0053] In other words, the adjustment assembly 40 also includes a plurality of pressure columns 42 and a plurality of adjustment members 43 provided on the base 20. Each pressure column 42 is respectively provided at the top corner of the quick-release pressure head 30. Each pressure column 42 can adjust the distance between itself and the battery 200 under the adjustment of the corresponding adjustment member 43, thereby also adjusting the pressing effect of the battery pressing device 100 on the battery 200.

[0054] In some optional embodiments of the present application, the adjusting member 43 is provided on the bottom plate 10 , and each adjusting member 43 passes through the bottom plate 10 and the base 20 and is movably connected to the pressure column 42 .

[0055] That is, the adjusting member 43 is provided on the bottom plate 10 and passes through the bottom plate 10 and the base 20 to connect with the pressing column 42. Thus, by adjusting the adjusting member 43 on the bottom plate 10, the pressing effect of the battery 200 can be adjusted, and the adjustment method is simpler and more convenient to operate.

[0056] Optionally, according to some embodiments of the present application, the press-fitting surface 31 is provided with a mounting hole 311 extending along the first direction, and the battery press-fitting device 100 further includes: an elastic member 51 and a guide column 52 .

[0057] The elastic member 51 is retractably disposed in the mounting hole 311 along a first direction. The guide post 52 is movably disposed in the mounting hole 311 . The first end of the guide post 52 is connected to the elastic member 51 . The second end of the guide post 52 can extend or retract into the mounting hole 311 .

[0058] In other words, as shown in FIG4 , a plurality of mounting holes 311 may be provided on the press-fitting surface 31 , each of which may be provided with an elastic member 51 and a guide post 52 . The elastic member 51 may be a rebound compression spring, and the guide post 52 may be disposed in the mounting hole 311 via a guide linear bearing 53 . The guide post 52 is disposed at the other end of the elastic member 51 and may extend out of the press-fitting surface 31 . When the battery press-fitting device 100 press-fits the battery 200 , the top cover of the battery 200 first contacts the guide post 52 , then continues to press the guide post 52 , causing it to retract into the press-fitting surface 31 until the battery 200 is pressed. After the battery 200 is press-fitted, the jig 300 is released, and the elastic member 51 , under the action of its elastic force, causes the guide post 52 to push the battery 200 away, thereby achieving separation of the battery press-fitting device 100 from the battery 200 .

[0059] Therefore, by setting the elastic member 51 and the guide column 52 structure, the elastic member 51 can rebound by its elastic force, and the guide column 52 can achieve a guiding effect. This structural combination can prevent the top cover of the battery 200 from sticking together with the quick-release press head 30 after the battery 200 is pre-spot welded, which effectively ensures the pressing effect of the battery 200 while allowing it to be quickly separated from the quick-release press head 30, thereby improving the assembly efficiency of the battery 200.

[0060] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
