Problems solved by technology

During the battery PACK assembly process, the tabs of the battery cells that make up the battery need to be flattened before welding is completed. At present, many power battery manufacturers only use simple manual tools to assist or use pure manual methods to complete the flattening of the tabs, which leads to The consistency of tab flattening is poor, the quality is not high, and because of poor contact of tabs, it is easy to cause hidden dangers such as poor welding in the subsequent sequence

Embodiment 1

[0032] In this embodiment, the size specification of the power battery 16 is 500mm×178mm×255mm, the height of the battery tab 17 is 25mm, and the width is 45mm.

[0033]When working, turn the handle of the elbow clamp first, clamp the power battery with the elbow clamp 1, and fix the whole device on the power battery 16; then turn the handle 6 on the cam 4, and the eccentric mechanism will drive the flattening mechanism below it to move, Usually, the pressure can be set in advance. If the pressure is too high, the pressure spring 15 will be triggered to drive the push plate and other flattening mechanisms to spring up to prevent the tab 17 from being crushed. The push plate 8 is equipped with a bearing 13, and the pressure roller 10 for flattening the lug 17 is installed on the bearing 13. The movement of the push plate 8 drives the pressure roller 10 to move together, and the gap between the two pressure rollers 10 is adjusted according to the difference of the battery module....

Embodiment 2

[0035] In this embodiment, the size specification of the power battery 16 is 700mm×190mm×250mm, the height of the battery tab is 25mm, and the width is 45mm.

[0036] Working principle is the same as embodiment 1. The stroke of the push plate 8 is 70 mm, and the distance between the two tabs 17 is 60 mm. The two push plates 8 can work together to flatten two tabs 17 at one time; the diameter of the pressure roller 10 is 10 mm, and the insulation treatment part 9 The diameter is 8mm, the length is 120mm, and the diameter series of the pressure roller 10 also includes 12mm, 14mm, 8.5mm and so on.

[0037] The invention is simple in structure, easy to operate, can be operated by a single person, and has reliable flattening function; the size of the eccentric mechanism and the bottom plate 2 can be adjusted according to the model of the battery module, so as to realize the flattening of battery lugs of various specifications The present invention can also be used in series to fla...

Abstract

The invention discloses a manual tool and a method for tab flattening of flexibly-packaged power batteries. The tool comprises a bottom plate, toggle clamps, eccentric mechanisms, flattening mechanisms, guide columns and pressure springs; the toggle clamps are mounted on two sides of the bottom plate through bolts and are used for clamping a power battery module and fixedly connecting the bottom plate with the power battery module temporarily; long holes are formed in the bottom plate to be used as moving tracks of the flattening mechanisms; the flattening mechanisms are arranged below the bottom plate; the eccentric mechanisms are arranged above the bottom plate; the flattening mechanisms and the eccentric mechanisms are connected through the guide columns; the guide columns are arrangedin the long holes of the bottom plate and are sleeved with the pressure springs. Tabs of a cell of the power battery module before welding can be flattened. The manual tool is simple and portable in structure, light, rapid in positioning and simple to operate; the manual tools can be combined conveniently and can be connected in series, and multiple groups of tabs can be flattened through one-timepositioning; the manual tool is high in universality and free of rebounding, can protect the tabs when the pressure is too high and can prevent the tabs from being crushed.

Description

technical field [0001] The invention relates to a flattening device for battery tabs, in particular to a manual tool and method for flattening tabs of soft pack power batteries. Background technique [0002] With the continuous development of society and economy, the number of automobiles continues to increase. Under the needs of the environment and the guidance of national policies, the electric vehicle industry has entered a period of rapid development. The soft pack power battery is characterized by its high safety performance, high energy density, low cost, Long life and other advantages, widely used. During the battery PACK assembly process, the tabs of the battery cells that make up the battery need to be flattened before welding is completed. At present, many power battery manufacturers only use simple manual tools to assist or use pure manual methods to complete the flattening of the tabs, which leads to The consistency of tab flattening is poor, the quality is not ...
