Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a battery follower mechanism adapted to battery charging and discharging. Background Art

[0002] During the production process of lithium batteries, the batteries need to be continuously charged and discharged to test and adjust battery performance. This process is also called the charge and discharge capacity of lithium batteries.

[0003] In order to ensure stable and reliable charging and discharging of lithium batteries, it is necessary to pay attention to the stability of the pressing between the battery pole and the probe, that is, the vertical projection position of the probe and the lithium battery pole needs to coincide. If the position of the probe and the lithium battery pole deviates, the probe will not be able to effectively contact the lithium battery pole, affecting the charging and discharging of the lithium battery.

[0004] Theoretically, when the probe queue and the lithium battery queue are facing each other, the lithium battery and its corresponding probe should be facing each other. However, in the actual production process, there are errors in the thickness of the lithium battery, the size of the separator, and the thickness error caused by the expansion of the lithium battery due to internal chemical reactions during charging and discharging. In particular, the above errors will accumulate in the lithium battery queue, resulting in the deviation of the lithium battery far from the contact point and its corresponding probe to a degree sufficient to affect the effective charging and discharging of the lithium battery.

[0005] The thickness and dimensions defined by each battery manufacturer are different. Existing equipment is a fixed structure, so the equipment must be redesigned to accommodate different thicknesses. It is not flexibly compatible with batteries of other thicknesses. Summary of the invention

[0006] In view of the above problems, the utility model proposes a battery follower mechanism.

[0007] The adaptive battery follower mechanism includes a needle plate mounting base assembly and a needle plate assembly; the needle plate mounting base assembly includes two horizontal and mutually parallel needle plate slide rail fixing plates, the direction in which the needle plate slide rail fixing plates extend is defined as the left-right direction, and the horizontal direction perpendicular to the left-right direction is the front-back direction; the lower end of the needle plate slide rail fixing plate is connected to an external device, and the upper end is provided with a needle plate movement slide rail in the left-right direction, a needle plate blocking block is provided on the two needle plate movement slide rails that can slide left-right, and two pull-out needle plate slide rails, one high and one low, are provided on the right side of the needle plate blocking block; the pull-out needle plate slide rails are connected to the needle plate assembly that can slide back and forth;

[0008] The needle plate assembly can be slidably moved forward and backward by the needle plate moving slider, and is connected to the pull-out needle plate slide rail on the left side; a probe slide rail in the front and rear direction is provided at the bottom right side of the needle plate moving slider, and several probe components that can slide forward and backward along the probe slide rail are provided on the probe slide rail; a reset cylinder that can slide forward and backward along the probe slide rail is provided at the front end of the frontmost probe component; a guide block is provided at the front end of the reset cylinder; the probe component is connected to the guide block through a reset tension spring; a needle plate handle is provided at the front end of the needle plate moving slider; a current connector and an adapter plate connected to an external circuit are provided on the top of the needle plate moving slider;

[0009] The probe component is connected to the probe rail through a probe slider, and a displacement sensor and a spring pin are provided at the top of the probe component; the right side of the probe component is provided with an equalizing rod assembly, a temperature probe and a probe in sequence from top to bottom; the probe corresponds to the pole of the external battery, and the equalizing rod assembly cooperates with the clamping head of the battery tray to assist in positioning the probe. In order to avoid a larger deviation between the front equalizing rod assembly and the clamping head of the battery tray, the equalizing rod assembly of the four probe components at the rear end is slightly longer than the equalizing rod assembly of the remaining probe components, so that the equalizing rod assembly at the rear end is initially aligned with the battery pole, and then pushes the shorter equalizing rod assembly at the front end to move forward to ensure guide compatibility.

[0010] More specifically, a cylinder fixing plate is provided at the lower end of the needle plate blocking block, and the cylinder fixing plate is connected to an external cylinder that can be pushed left and right.

[0011] More specifically, the reset cylinder is arranged on the probe slide rail through a positioning slider, an initial positioning plate is provided at the right end of the positioning slider, a cylinder pull seat is provided on the initial positioning plate, a cylinder extension shaft in the front and rear directions is fixed on the cylinder pull seat, and an initial position cylinder that can be pushed forward and backward is connected to the front end of the cylinder extension shaft to provide power for resetting the probe component.

[0012] More specifically, the dividing rod assembly includes an dividing rod fixing seat; the dividing rod fixing seat is connected to the probe component, an dividing rod baffle is provided on the left side of the dividing rod fixing seat, and a V-shaped positioning block that can contact an external battery is connected to the right side through the dividing rod, and an dividing rod spring is provided on the dividing rod.

[0013] The working steps of the utility model include:

[0014] 1. The external cylinder pushes the needle plate assembly forward and backward through the cylinder fixing plate, so that the rear end probe component aligns with the battery pole and the tray clamp.

[0015] 2. Push the needle plate blocking block left and right to press the probe component onto the battery pole, and accurately position the battery tray through the dividing rod fitting on the probe component; after positioning, charge and discharge the battery.

[0016] 3. After charging and discharging is completed, the probe component is pushed by the reset cylinder to complete the reset.

[0017] The utility model has the advantages of solving the interference of thickness error and battery expansion on battery charging and discharging during battery charging and discharging, improving the guide compatibility, having a simple structure and being easy to disassemble and replace, and conveniently resetting the probe after charging and discharging.
