Embodiment 1

[0060] The battery hemming device provided in the embodiment of the present invention is mainly used in the scene of hemming button batteries (i.e., "soft-packed round lithium button batteries"). The quality of battery production.

[0061] The battery hemming device provided in this embodiment includes a pre-hemming device 1, a fine hemming device 2, and a finishing hemming worker for transferring the battery from the pre-hemming station of the pre-hemming device 1 to the finishing hemming device 2 Bit flow device.

[0062] Such as figure 1 , figure 2 , Figure 4 and Figure 5 As shown, the battery 3 includes a battery body 31 and tabs, and the tabs include a fitting section 32 connected to the battery body 31; fold.

[0063] The fine hemming device 2 includes a hemming mold 21 and a clamping device 22 for clamping the battery body 31 ; the hemming mold 21 is provided with a through hole 211 .

[0064] The clamping device 22 is also used to drive the battery body 31 to...

Embodiment 2

[0096] The battery processing equipment provided in this embodiment includes downstream equipment and the battery folding device as in Embodiment 1; the circulation device of the battery folding device is used to transport the folded battery to the downstream equipment. Embodiment 1 describes the specific structure and technical effects of the battery hemming device, and this embodiment 1 cites the battery hemming device, which also has its technical effects.

[0097] To sum up, the battery processing equipment provided in this embodiment performs secondary folding on the tabs of the battery, so that the tabs of the battery after the folding process are more closely attached to the round body of the button battery, thereby improving the production capacity of the button battery. Quality, and has the characteristics of high efficiency, high precision, high safety factor and low cost.

Abstract

The invention discloses a battery edge folding device and battery processing equipment. When a battery is subjected to the edge folding procedure, a pre-edge-folding device bends an attaching sectionof the battery for the first time in the direction close to a body, then the battery is transferred to a fine edge folding station through a transferring device, and then the battery body is clamped through a clamping device to enable the battery to penetrate through the through hole; in the process, the attaching section is extruded by the hole wall of the through hole to be bent, so that the edge folding procedure of the attaching section is completed; the attaching section is bent for the first time through the pre-edge-folding device, so that the deformation amount of the attaching sectionwhen the attaching section penetrates through the through hole is reduced; then the attaching section is extruded through the hole wall of the through hole to be bent for the second time in the direction close to the battery body, so that the rebound phenomenon of the attaching section due to overlarge edge folding angle during final bending is avoided; and meanwhile, the aperture size of the through hole does not need to consider the size error during upper and lower die assembly, the attaching degree to the battery body can be increased, the attaching section is closer to the battery body,and the production quality of the battery is improved.

Description

technical field [0001] The invention relates to the technical field of battery folding, in particular to a battery folding device and battery processing equipment. Background technique [0002] Batteries are divided into three types: aluminum shell batteries, soft-packed round button lithium batteries (referred to as "button batteries"), and cylindrical batteries. Usually, mobile phone batteries are made of aluminum shell batteries, digital products such as Bluetooth mostly use soft-pack batteries, and laptop batteries use cylindrical batteries in series and parallel combinations. [0003] Among them, the soft pack of the soft pack battery will provide a buffer space for the battery cell to avoid explosion, and has the characteristics of light weight, high energy density and recyclable use. The commonly used pouch battery is easy to fold, and only needs to fold the two sides by 90 degrees to complete the folding process. [0004] However, if figure 1 As shown, the folding...
