Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium batteries, in particular to a battery cell support assembly system for a lithium battery pack production line of an electric motorcycle. BACKGROUND

[0002] With the increasing attention to environmental protection and energy sustainable development worldwide, electric motorcycles have become the preferred means of transportation for more and more people due to their green and convenient characteristics, and the market demand has also shown a rapid growth trend. As the core power source of electric motorcycles, lithium batteries provide key support for the normal operation of vehicles. The performance and quality of lithium batteries directly determine important indicators such as the length of the electric motorcycle's range, the level of safety performance, and the length of the service life.

[0003] In the production and manufacturing process of lithium batteries, the battery cell support plays a crucial role. It not only securely fixes the battery cells to prevent them from shaking or shifting during vehicle operation, but also provides necessary electrical connection channels to ensure stable current transmission, while having good heat dissipation function to ensure that the temperature of lithium batteries during operation is within a reasonable range, thereby ensuring the stability and safety of the overall operation of lithium batteries.

[0004] For example, the power lithium battery PACK line battery cell support automatic assembly equipment with publication number CN108767149A uses multiple groups of non-adjustable assembly and carrying clamping pieces, and cooperates with the driving end of the assembly and carrying clamping cylinder to realize three-point clamping of the battery cells. Although it can simultaneously clamp and assemble multiple battery cells to the lower support, However, when clamping different size battery cells, the centerline distance between adjacent battery cells cannot be automatically adjusted according to the size of the battery cells. The ideal assembly distance between the centerlines of the adjacent two groups of battery cells changes with the diameter of the battery cells during assembly, which leads to the problem that the adjacent distance of small size battery cells is too large during actual assembly, resulting in that the overall size of the assembled lithium battery exceeds the reasonable range, occupies too much space, and affects the overall layout and performance of the vehicle. In addition, this clamping and grabbing method has high requirements for the initial distribution state of the battery cells. It needs to be combined with a special battery cell distribution device, i.e., multiple battery cells are distributed at equal intervals according to specific requirements in advance to assist the device to realize clamping and grabbing operation, thereby increasing the complexity and cost of using the device.

A communication groove 210 is arranged between the top of the two sides of the piston cavity 28 and the interior of the arc-shaped rubber plate 23. A plurality of air pipes 211 are arranged on the elastic arc-shaped plate 22 and communicate with the interior of the arc-shaped rubber plate 23. The plurality of air pipes 211 are synchronously connected with the external negative pressure air suction device.

When the surface of a battery cell contains a large amount of dust and cannot be adsorbed and lifted, the vacuum state in the interior of the plurality of arc-shaped rubber plates 23 disappears, the remaining battery cells are adsorbed by the plurality of suction cups on the two sides, thereby temporarily limiting the battery cells from falling and limiting the corresponding elastic arc-shaped plates 22 from resetting. The elastic arc-shaped plate 22 deformed by the falling of the battery cell resets the arc-shaped rubber plate 23, thereby enabling the inner wall of the suction hole 27 to fully adhere to the corresponding limiting column 25.

The electric push rod drives the movable seat 31 to rise with the battery and the gear 38. During the rising of the gear 38, the engaged toothed plate two 37 rotates, causing the toothed plate one 36 to carry the diaphragm 35 to rise by a multiple of the stroke, separating the battery and the battery on one side from interference.
