Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a cup with an end cover sleeve. Background Art

[0002] In the field of battery manufacturing, the liquid injection process is crucial for the performance and quality of batteries. In the traditional liquid injection method for cylindrical battery cup sleeves, the upper port of the cup sleeve is usually open to facilitate the liquid injection operation. However, this open design has obvious defects. Since the port of the cup sleeve is open, the contact area between the electrolyte inside and the external environment is relatively large, which leads to a relatively fast evaporation rate of the electrolyte. The rapid evaporation of the electrolyte not only causes waste of the electrolyte and increases production costs, but also may pollute the production environment and pose a potential threat to the health of operators.

[0003] After retrieval, Chinese Patent Publication No.: CN220544199U discloses a liquid injection cup sleeve for a cylindrical lithium-ion battery, including a sleeve, a funnel mechanism and a limiting mechanism. A steel shell is sleeved on the inner wall of the sleeve. The funnel mechanism is installed in the inner wall of the sleeve, and the limiting mechanism is installed at the lower end of the inner wall of the sleeve. In this liquid injection cup sleeve for a cylindrical lithium-ion battery, through the setting of the funnel mechanism, when it is necessary to pour electrolyte into the steel shell, the sleeve can be sleeved on the steel shell. Then, under the magnetic attraction connection of the magnetic attraction block and the magnetic attraction seat, the arc-shaped funnel is clamped into the sleeve, and the injection nozzle of the arc-shaped funnel is inserted into the injection port of the steel shell. Then, the electrolyte is introduced into the sleeve by using an injection device. With the assistance of the arc-shaped funnel, the electrolyte can be completely introduced into the steel shell, avoiding the leakage of the electrolyte and effectively improving the working stability and convenience of the device.

[0004] Although this device has certain improvements and can facilitate the introduction of electrolyte and fix battery steel shells with different diameters, it still has the following deficiencies.

[0005] 1. This device does not solve the problem that the existing cup sleeve port is open, the contact area between the electrolyte inside and the external environment is relatively large, resulting in a relatively fast evaporation rate of the electrolyte.

[0006] 2. Although this device can clamp and fix battery steel shells with different diameters, the lengths of different models of battery steel shells are also different.

[0033] Refer to Figure 1 - Figure 2 As shown in the figure, an embodiment provided by the present invention: a cup with an end cover includes a sleeve 1, and the sleeve 1 is the battery injection cup, which is used to place the battery steel shell. A sealing gasket 2 is fixedly connected to the lower surface of the sleeve 1. A cylinder cover 3 is inserted into the upper surface of the sleeve 1. The lower surface of the cylinder cover 3 fits with the upper surface of the sleeve 1. The cylinder cover 3 can be flexibly disassembled and assembled. When the installation is completed, it can reduce the area of the opening on the sleeve 1, reduce the contact area between the electrolyte and the external air, slow down the evaporation speed, and improve the utilization rate of raw materials. A through groove 301 is opened on the upper surface of the cylinder cover 3. After the cylinder cover 3 is closed, the through groove 301 can facilitate the introduction of the electrolyte, and a funnel can be placed at the through groove 301 to facilitate the introduction of the electrolyte. A quick-release component is arranged inside the cylinder cover 3, and the quick-release component can ensure the stability of the installation of the cylinder cover 3. A positioning component is arranged inside the sleeve 1, and the positioning component can fix cylindrical battery steel shells of different models, facilitating the subsequent introduction of the electrolyte.

[0034] Refer to Figure 1 、 Figure 2 、 Figure 4 As shown in the figure, the positioning component includes a hollow column 51. The inner wall of the hollow column 51 is elastically connected with a slide column 52 through a connecting spring 56. The upper surface of the slide column 52 is fixedly connected with a placing block 53. The placing block 53 and the slide column 52 will move longitudinally synchronously to adapt to battery steel shells of different heights. The outer wall of the placing block 53 fits with the inner wall of the sleeve 1, which can ensure the stability when the battery steel shell is installed. A placing groove 501 is opened on the upper surface of the placing block 53, and the bottom end of the battery steel shell can be placed in the placing groove 501. The positioning component further includes a card slot 502. The inner wall of the slide column 52 is elastically connected with a U-shaped plate 55 through a compression spring 54. The U-shaped plate 55 is set in a U shape, and the lower surface of the U-shaped plate 55 is set as an inclined surface. When the inclined surface of the U-shaped plate 55 is squeezed, the U-shaped plate 55 will move to the left.

[0035] Reference Figure 1 -[[-END]] Figure 3 As shown in FIGS. -,, the quick-release assembly includes a rubber ring 41. An annular groove 401 is formed on the outer wall of the barrel cover 3. The rubber ring 41 fits into the annular groove 401. The rubber ring 41 is used to maintain sealing. A limiting block 42 is elastically connected to the inner wall of the barrel cover 3 through a limiting spring 43. A limiting groove 402 is formed on the inner wall of the left side of the sleeve 1. The limiting block 42 fits into the limiting groove 402.

[0036] Reference Figure 1 、 Figure 2 、 Figure 4 As shown in FIGS. -,, the sliding column 52 penetrates and is slidably connected to the upper surface of the hollow column 51, and slides longitudinally. One end of a connecting spring 56 is fixedly connected to the lower surface of the sliding column 52, and the other end of the connecting spring 56 is fixedly connected to the inner wall of the bottom end of the hollow column 51. When the sliding column 52 moves downward, it will squeeze the connecting spring 56 to generate a reaction force. The lower surface of the hollow column 51 is in contact with the inner wall of the bottom end of the sleeve 1, which can ensure stability during placement. The placement groove 501 is formed as a flat-top cone with a large upper opening and a small lower opening. Cylindrical battery steel shells with different diameters will contact different positions on the inner wall of the placement groove 501. The placement block 53 is inserted into the upper surface of the sleeve 1 and can be taken out. A clamping groove 502 is formed on the inner wall of the right side of the hollow column 51. There are multiple groups of clamping grooves 502, and the multiple groups of clamping grooves 502 are longitudinally and evenly distributed on the inner wall of the right side of the hollow column 51. One end of a compression spring 54 is fixedly connected to the left surface of the U-shaped plate 55, and the other end of the compression spring 54 is fixedly connected to the inner wall of the left side of the sliding column 52. When the U-shaped plate 55 moves leftward, it will squeeze the compression spring 54 to generate a reaction force. When the U-shaped plate 55 moves leftward, it will also disengage from the clamping groove 502. The U-shaped plate 55 penetrates and is slidably connected to the right surface of the sliding column 52. The U-shaped plate 55 is inserted into the inner wall of the clamping groove 502, which can limit the sliding column 52 and ensure the height stability of the sliding column 52.

[0037] Reference Figure 1 -[[-END]] Figure 3 As shown in FIGS. -,, the rubber ring 41 is fixedly connected to the top end of the inner wall of the sleeve 1. The rubber ring 41 is inserted into the inner wall of the annular groove 401. The left end of the limiting block 42 is set as a quarter sphere with the arc surface facing downward. Squeezing the lower surface or side surface of the limiting block 42 will cause the limiting block 42 to move to the right. The limiting block 42 is inserted into the inner wall of the limiting groove 402, which can limit the barrel cover 3 and prevent the barrel cover 3 from separating from the sleeve 1. The limiting block 42 penetrates and is slidably connected to the left surface of the barrel cover 3. One end of the limiting spring 43 is fixedly connected to the right surface of the limiting block 42, and the other end of the limiting spring 43 is fixedly connected to the inner wall of the right side of the barrel cover 3. The limiting block 42 slides horizontally. When the limiting block 42 moves to the right, it will retract into the barrel cover 3 and squeeze the limiting spring 43 to generate a reaction force.

[0038] Working principle: When using this device, first place the battery steel shell in the placement groove 501, the bottom end of the battery steel shell will contact the inner wall of the placement groove 501, and then the lower surface of the tube cover 3 will fit the upper surface of the battery steel shell, and move the tube cover 3 downward to make it plug into the sleeve 1. During plugging, the arc surface of the limit block 42 will be squeezed, and the limit block 42 will retract into the tube cover 3 to release the obstruction and squeeze the limit spring 43 to generate a reaction force, and the rubber ring 41 will also be squeezed and deformed to release the obstruction. When the plugging is completed, the rubber ring 41 will recover under its own elasticity and plug into the annular groove 401 to form a seal. Then rotate the tube cover 3 to drive the limit block 42 and the limit spring 43 to rotate. When the limit block 42 and the limit groove 402 are aligned, the reaction force of the limit spring 43 will push the limit block 42 and the annular groove 401 to plug into a limit, thereby limiting the sleeve 1 and the tube cover 3.

[0039] When the cylinder cover 3 is inserted into the sleeve 1, it will also drive the battery steel shell to move downward and squeeze the placement block 53. The placement block 53 and the sliding column 52 will move downward. The sliding column 52 moving downward will squeeze the connecting spring 56 to generate a reaction force, and the sliding column 52 moving downward will also drive the compression spring 54 and the U-shaped plate 55 to move downward. When the U-shaped plate 55 moves downward, the inclined surface will be squeezed, and the U-shaped plate 55 will move to the left to retract the sliding column 52 to release the obstruction, and will squeeze the compression spring 54 to generate a reaction force. When the sliding column 52 stops moving, the reaction force of the compression spring 54 will push the U-shaped plate 55 to move to the right and plug it into another slot 502 to form a limit, ensuring that the battery shell is stably fixed, and then the electrolyte is injected from the through slot 301.

[0040] After the injection is completed, the rotating cylinder cover 3 drives the limit block 42 to rotate. When the limit block 42 rotates, the arc surface of the side will be squeezed, and the limit block 42 will retract into the cylinder cover 3 to release the limit, and will squeeze the limit spring 43 to generate a reaction force. After the limit is released, the cylinder cover 3 is moved upward and taken out of the sleeve 1. The limit block 42 will recover under the push of the limit spring 43, and then the battery cover is installed and the battery steel shell is removed.

[0041] After use, the hollow column 51, the sliding column 52 and the placement block 53 can be poured out by turning the sleeve 1 upside down. After pouring out, the U-shaped plate 55 is pressed to retract it into the sliding column 52, so that the limit on the sliding column 52 can be released, allowing the sliding column 52 to move longitudinally to a suitable position.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
