Referring to fig. 1-2, fig. 1 is a schematic structural diagram of an embodiment of a pressing device of a battery case according to the present invention, and fig. 2 is a schematic sectional structural diagram of the pressing device of the battery case shown in fig. 1.
In one embodiment, the pressing device includes a supporting base 1, the supporting base 1 is fixed and rotatably supports a pressing component 2 therein. The pressing component 2 is used for pressing the opening end of the battery shell 3, and the other end of the battery shell 3 is placed in a supporting fixture (not shown). The pressing component 2 can drive the battery shell 3 to rotate relative to the supporting seat 1, and meanwhile, the hob (not shown) presses the battery shell 3 to roll the groove on the hob, so that the groove rolling operation of the battery shell 3 is completed in a matching manner.

Referring to fig. 1-4, fig. 3 is a partial schematic structural view of a pressing device of the battery case shown in fig. 1, and fig. 4 is another partial schematic structural view of the pressing device of the battery case shown in fig. 1.
In one embodiment, the pressing assembly 2 includes an outer sleeve 22 and an inner sleeve 23 nested with each other, i.e., the outer sleeve 22 is sleeved outside the inner sleeve 23, and the inner sleeve 23 is located in the outer sleeve 22. A first gap 24 is formed between the inner wall of the outer sleeve 22 and the outer wall of the inner sleeve 23, and the first gap 24 can allow the side wall of the battery shell 3 to be inserted into and held in the first gap 24, so that the pressing component 2 presses the opening end of the battery shell 3 and drives the battery shell 3 to rotate. Wherein the inner wall of the outer sleeve 22 is in close contact with the outer peripheral wall of the battery case 3.
The inner sleeve 23 is provided with a first air intake passage 231 communicating with the inside of the battery case 3, and the outer sleeve 22 is provided with a second air intake passage 221 communicating with the first air intake passage 231 and the outside atmosphere. The air in the external atmosphere environment where the pressing component 2 is located can enter the battery housing 3 along the second air inlet channel 221 and the first air inlet channel 231 in sequence to participate in forming airflow circulation, so that air circulation is facilitated during dust collection, and residual dust and debris in the battery housing 3 can be continuously sucked and removed.
Further, the inner sleeve 23 includes an inner sleeve main body 232 and a latch 233 provided on the outer periphery of the inner sleeve main body 232. The first gap 24 is located between the inner wall of the outer sleeve 22 and the outer wall of the latch 233, and the inner wall of the outer sleeve 22 and the outer wall of the latch 233 cooperate to grip the side wall of the battery housing 3. And a second gap 25 is further formed between the inner wall of the latch 233 and the outer wall of the inner sleeve main body 232, the second gap 25 being at least a part of the first air intake passage 231.
Specifically, a circumferential groove 2321 is formed in the outer wall of the inner sleeve main body 232, and the groove 2321 is communicated with the second air intake passage 221. The latch 233 is an outer wall below the groove 2321. The outer wall of the inner sleeve main body 232 below the latch 233 is retracted inward to form a first gap 24 for receiving the open end of the battery case. Meanwhile, a plurality of vent holes are formed at intervals along the circumferential direction at the bottom of the groove 2321, the vent holes are communicated with the groove 2321 and the inside of the battery shell 3, and at the moment, the vent holes are the first air inlet channel 231. Thus, the first air intake passage 231, the recess 2321 and the second air intake passage 221 are sequentially communicated, and external air is supplied into the inner sleeve 23. The gas flow direction of the outside gas into the inner sleeve 23 is shown by the dashed arrows in fig. 4.
It should be noted that the first air intake channel 231 extends along the vertical direction Y or an included angle between the extending direction and the vertical direction Y is smaller than 90 degrees. In this way, since the negative pressure is formed by the air exhaust, the air flow is blown downward to the inside of the battery case 3 through the first air inlet channel 231, which is beneficial to carry away the dust and debris inside the battery case 3 through the air flow. In the present embodiment, the first air intake channel 231 extends along the vertical direction Y for example, but the extending direction of the first air intake channel 231 is not limited thereto.
Preferably, the second air intake passage 221 extends in the horizontal direction X to facilitate the airflow that is formed from the second air intake passage 221, the first air intake passage 231 to the inside of the battery case 3, thereby removing dust and debris remaining in the battery case 3.
Further, the inner sleeve main body 232 is hollow and communicates with the inside of the battery case 3, and the air flows therethrough. The inner diameter d of the hollow interior gradually decreases in a direction away from the battery case 3, i.e., the thickness of the side wall of the inner sleeve main body 232 gradually increases in a direction away from the battery case 3. Therefore, when the pressing component 2 presses the battery shell 3, the thickness of the sidewall of the inner sleeve main body 232 is increased, which is beneficial to ensuring the structural stability of the inner sleeve main body 232, and the service life of the inner sleeve main body 232 is not affected by the thinness of the sidewall. In addition, the inner diameter of the inner sleeve main body 232 gradually decreases along the direction away from the battery housing 3, so that the inner wall of the inner sleeve main body 232 inclines towards the direction away from the outer sleeve 22, and thus the tab 31 in the battery housing 3 correspondingly inclines under the action of the inner wall of the inner sleeve main body 232, a mechanism used in a subsequent process (such as secondary dust collection) can be avoided, and the risk that the tab 31 is damaged by pressure in the subsequent process is effectively reduced.
In an embodiment, the pressing assembly 2 further includes a main shaft 26 and an auxiliary shaft 27, wherein the main shaft 26 is sleeved on the periphery of the auxiliary shaft 27, and the main shaft 26 can drive the auxiliary shaft 27 to rotate synchronously.
