Detailed Description
The following description of the embodiments of the present utility model will be made in detail and with reference to specific embodiments of the present utility model, but it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.
As shown in fig. 1-5, the oscillating device for lithium ion battery liquid injection of the utility model comprises a base 1, an oscillating frame 2 and a heating pipe 3.
Wherein, base 1 is this oscillating device's bearing structure, rotates on the base 1 and is provided with rotor 11.
The vibration frame 2 is used for fixing the lithium ion battery after liquid injection, the driven wheel 21 is fixedly arranged on the vibration frame 2, and when the rotating wheel 11 rotates, the driven wheel 21 is driven to move along a circular track on a horizontal plane, so that the vibration frame 2 fixedly connected with the driven wheel 21 and the battery fixed on the vibration frame 2 move along the circular track on the horizontal plane, the electrolyte in the battery is stably vibrated, the electrolyte cannot be fused with the air in the battery again, and the exhaust and infiltration efficiency of the electrolyte are accelerated.
As shown in fig. 3, in order to realize that the rotating wheel 11 drives the driven wheel 21 to move along a circular track on a horizontal plane, the rotating wheel 11 may be configured to include a main wheel 111 and an eccentric wheel 112, where the main wheel 111 is rotatably disposed on the base 1, the eccentric wheel 112 is fixedly disposed on a side of the main wheel 111 away from the base 1 and is rotatably connected with the driven wheel 21, a space is provided between an axis of the eccentric wheel 112 and a rotation axis of the main wheel 111, that is, the eccentric wheel 112 is eccentrically disposed with the main wheel 111, and the driven wheel 21 is driven to perform eccentric movement by using the eccentric structure.
The rotation of the rotating wheel 11 needs other mechanisms to drive, if the rotating wheel is directly connected with an output shaft of a driving device, the rotating wheel can interfere with other components of the oscillating device, therefore, a driving wheel 12 is rotatably arranged on the base 1, a driving motor 13 is fixedly arranged on the base 1, an output end of the driving motor 13 is fixedly connected with the driving wheel 12, a driving belt 14 is sleeved between the driving wheel 12 and the main wheel 111, the driving motor 13 can be arranged at the bottom or one side of the base 1, and when the driving motor 13 is started, the driving wheel 12 can be driven to rotate, and the main wheel 111 is driven to rotate by the transmission of the driving belt 14.
Because the driven wheel 21 is rotationally connected with the rotating wheel 11 and lacks a mechanism for limiting the oscillating frame 2, the oscillating direction of the oscillating frame 2 on the base 1 is irregular, and the problem of low oscillating efficiency possibly exists; similarly, a limit groove 101 can be formed in the base 1, a limit rod 22 is fixedly arranged on the vibration frame 2, the limit rod 22 penetrates through the limit groove 101 and is connected with the limit groove 101 in a clearance fit manner, and the limit rod 22 can shake in the limit groove 101 within a certain range by utilizing the clearance, so that the movement range of the limit rod 22 and the vibration frame 2 is prevented from being overlarge; specifically, in order to prevent the stop lever 22 from separating from the stop groove 101, it is preferable that both ends of the stop lever 22 are fixedly connected with the oscillating frame 2, as shown in fig. 1, by using this structure, the middle position of the stop lever 22 and the stop groove 101 can be in clearance fit, and the stop lever 22 cannot separate from the stop groove 101.
In order to further improve the oscillation regularity and stability of the oscillating frame 2, a small wheel 15 can be rotatably arranged on the base 1, a driving rod 16 is fixedly arranged on one side of the small wheel 15 far away from the base 1, a space is arranged between the axial direction of the driving rod 16 and the rotation axis of the small wheel 15, and the driving rod 16 is rotatably connected with a limit rod 22, as shown in fig. 2, the driving rod 16 and the small wheel 15 are eccentrically arranged, which can limit the movement range of the limit rod 22 and enable the limit rod 22 and the oscillating frame 2 to oscillate stably; specifically, as shown in fig. 2, the small wheel 15, the driving rod 16 and the limiting rod 22 may be further provided in plural, so that the vibration stability of the vibration frame 2 is further enhanced.
The heating pipe 3 is used for heating the battery fixed on the oscillating frame 2, the heating pipe 3 is fixedly arranged on the base 1, the heating pipe 3 can be a continuous S-shaped bent pipe, and the heating effect can be realized by introducing hot water into the heating pipe; the higher the temperature of the infiltrating electrode is, the lower the viscosity of the electrolyte is, the larger the specific surface area of the infiltration is, the faster the infiltration speed of the electrolyte is, and the shorter the infiltration time is, so that the infiltration efficiency of the electrolyte can be improved by the arrangement of the heating pipe 3.
In order to improve the heating effect of the heating pipe 3, the side wall of the oscillating frame 2 can be hollow, so that heat spreading is quickened.
The working principle of the oscillating device for lithium ion battery liquid injection of the utility model is as follows:
the battery after liquid injection is fixed on the oscillating frame 2, and after the driving motor 13 is started, the driving wheel 12 is driven to rotate, and the rotating wheel 11 is driven to rotate by the transmission of the transmission belt 14, so that the driven wheel 21 moves along a circular track on a horizontal plane, and the effects of accelerating the infiltration and the exhaust of electrolyte in the battery are realized; during the period, the shape structure of the base 1 and the oscillating frame 2, the clearance fit of the limiting rod 22 and the limiting groove 101 and the limitation of the small wheel 15 and the driving rod 16 to the limiting rod 22 can enable the oscillating frame 2 to oscillate more stably and regularly, so that the battery oscillates more stably.
