Description

Technical Field

[0001] This invention relates to the field of new energy battery production technology, specifically to a liquid injection device for new energy battery production. Background Technology

[0002] In the production of new energy batteries, the electrolyte injection process is a crucial step, its core task being the precise injection of a measured amount of electrolyte into the battery casing. The quality of this process directly determines the battery's energy density, cycle life, and safety performance. The key to effective electrolyte injection lies in ensuring that the electrolyte can quickly and fully wet the electrode plates while minimizing residual air bubbles.

[0003] Currently, the mainstream liquid injection processes in the industry are mainly divided into top liquid injection and bottom liquid injection.

Activating the vacuum pump 501 can evacuate the vacuum tank 503. The presence of the vacuum tank 503 can ensure the vacuum level, achieving stable vacuuming of the new energy battery and achieving bottom liquid injection.

[0033] Specifically, turning on the first motor 801 can drive the first gear 802 to rotate, the rotation of the first gear 802 will drive the second gear 803 to rotate, the rotation of the second gear 803 will drive the third rotating shaft 804 to rotate, thereby driving the deflection lifting rod mechanism 6 to deflect and change position, thereby controlling the deflection state of the deflection frame 7.

[0034] The support bracket mechanism 9 includes a second motor 901 mounted on the deflection frame 7. The output shaft of the second motor 901 is fixedly connected to the displacement shaft 902. The displacement shaft 902 is provided with reverse symmetrical threads. The displacement shaft 902 is threadedly connected to two symmetrically arranged displacement frames 903.

A retaining strip is provided on the inner side of the rotating sleeve 1003 along its axial direction. A retaining groove is provided on the axial direction of the rotating shaft 1002. The retaining strip is located in the retaining groove. The rotating shaft 1002 passes through the rotating sleeve 1003. A first bevel gear 1004 is fixedly connected to the outer side of the rotating sleeve 1003. The first bevel gear 1004 meshes with a second bevel gear 1005. The second bevel gear 1005 is fixedly connected to a conveying drive shaft 1006. The conveying drive shaft 1006 and the deflection frame 7 are rotatably connected. The conveying deflector mechanism 11 includes a first conveying wheel 1101 rotatably connected to the deflection frame 7. The first conveying wheel 1101 is driven to the conveyor belt 1102. Several deflectors 1103 are fixedly connected to the outer side of the conveyor belt 1102. The conveyor belt 1102 is driven to the second conveying wheel 1104. The second conveying wheel 1104 is rotatably connected to the deflection frame 7. The second conveying wheel 1104 is coaxially fixedly connected to the conveying drive shaft 1006. The deflection frame 7 is fixedly connected to the contact frame 1105. The contact frame 1105 contacts the inner side of the conveyor belt 1102.

[0035] Specifically, activating the second motor 901 drives the displacement shaft 902 to rotate, thereby controlling the spacing between the two displacement frames 903. This adapts to the transport of new energy batteries of different sizes. The edges of the new energy batteries can be placed on the support wheels 904. Due to the presence of the contact frame 1105, the new energy batteries can be stably placed in the center. At this time, activating the third motor 1001 drives the rotating shaft 1002 to rotate, which in turn drives the rotating sleeve 1003 to rotate. The rotation of the rotating sleeve 1003 drives the first bevel gear 1004 to rotate, which in turn drives the second bevel gear 1005 to rotate, thereby driving the conveyor drive shaft 1006 to rotate.

[0036] Example 2, see below. Figures 1-5 and Figure 7 In this embodiment of the invention, the deflection lifting rod mechanism 6 includes a first rotating shaft 601 rotatably connected to the liquid storage shell 1, the first rotating shaft 601 being fixedly connected to a rotating shell 602, a second linear motor 603 being fixedly connected inside the rotating shell 602, the second linear motor 603 being fixedly connected to a slider 604, the slider 604 being fixedly connected to a telescopic rod 605, the telescopic rod 605 passing through the rotating shell 602, the telescopic rod 605 and the rotating shell 602 being slidably connected, the telescopic rod 605 being fixedly connected to a second rotating shaft 606, and the second rotating shaft 606 being rotatably connected to the deflection frame 7.

[0037] Specifically, turning on the second linear motor 603 allows the slider 604 to move along the rotating shell 602, thereby controlling the length of the telescopic rod 605 extending out of the rotating shell 602. This allows for adjustment of the overall height and angle of the deflection frame 7 to adapt to different liquid injection processing environments.

[0038] In the implementation of this invention, the state of the support bracket mechanism 9 is first adjusted according to the different sizes of the new energy batteries, and then the distance between the two conveying plate mechanisms 11 is adjusted. At this time, the new energy battery that needs to be injected can be placed on the support bracket mechanism 9 and locked between the two conveying plate mechanisms 11. Then, the conveying drive mechanism 10 is activated, which drives the conveying plate mechanism 11 to move the new energy battery. At this time, the deflection drive mechanism 8 is activated, which can drive one of the deflection lifting rod mechanisms 6 to deflect and reposition, thereby adjusting the overall height of the deflection frame 7. With the deflection lifting rod mechanism 6, the conveying angle of the deflection frame 7 can be adaptively adjusted, thereby controlling whether the new energy battery is injected with liquid from the top or the bottom. The top injection can be directly achieved through the injection mechanism 4, while when the bottom injection port of the new energy battery is immersed below the liquid surface in the liquid storage shell 1, the bottom injection is achieved through the suction mechanism 5.

[0039] This invention, by setting up a lifting top plate mechanism 3, can drive the liquid injection mechanism 4 and the air suction mechanism 5 to rise and fall, thereby adapting to different liquid injection operation environments. The liquid injection mechanism 4 can perform liquid injection on the battery, and the air suction mechanism 5 can perform vacuum treatment on the battery, thereby realizing liquid entry from the bottom liquid injection port of the battery. The deflection drive mechanism 8 can drive the deflection lifting rod mechanism 6 to deflect and reposition, thereby adjusting the state of the deflection frame 7, thus quickly realizing the switching between top liquid injection and bottom liquid injection. The support bracket mechanism 9 can transport new energy batteries of different sizes. In conjunction with the transport drive mechanism 10, it can drive the transport baffle mechanism 11, thereby driving the continuous transport of new energy batteries and improving the efficiency of liquid injection in new energy battery production.
