Problems solved by technology

[0004] More importantly, due to the extremely thin thickness of the tabs, during the laser cutting process of the tabs, the tabs are prone to flutter and wrinkles due to the relevant force, and the fluttering and wrinkled tabs will make the The cutting accuracy is not high, resulting in deviation, which affects the quality of the product
Moreover, in the design of the existing battery tab laser cutting device, for extremely thin tabs, the finished pole piece and tab waste after cutting are driven to be unloaded by the operation of the material roller, and the finished pole piece and the tab waste are not separated. Easy to separate; and only through the operation of the material roller to drive the blanking, the finished pole piece and tab waste after cutting are prone to flutter and bulge under the blowing of the air knife, so that the entire tab roll material swings, which is not conducive to laser focus cut

Embodiment 1

[0037] The battery tab laser cutting device of this embodiment is used for laser cutting the tab. see figure 1 As shown, the cutting device includes a laser head 1, a roller assembly 2, a cutting pallet 3, a dust cover 4 and a waste material unloading mechanism 5; the roller assembly includes a feed roller 21 and a discharge roller 22; the cutting Supporting plate 3 is arranged between described feeding roller 21 and described discharge roller 22; Said cutting supporting plate 3 has cutting opening 31; Said cutting opening 31 is positioned at the optical path of light output of said laser head 1; So The inlet end of the dust removal cover 4 is set at the cutting opening 31 ; the waste material unloading mechanism 5 is set at the discharge end of the cutting pallet 3 .

[0038] During laser cutting of battery tabs, the battery tabs unwind and pass through the feed roller 21 of the roller assembly 2 and enter the cutting pallet 3, and when the battery tabs pass through the cutt...

Embodiment 2

[0053] The battery lug laser cutting device of this embodiment is the same as that of Embodiment 1, the difference is that, see Figure 4 with Figure 5 Shown, the waste material unloading mechanism 5 of this device is suction waste material wheel 50. The waste suction wheel 50 is located at the discharge end of the cutting pallet 3 , and is located on the other side opposite to the inlet of the dust removal cover 4 along the running track of the cut battery tab. Wherein, the suction waste chamber 57 is located between the discharge end of the cutting pallet 3 and the feed end of the discharge roller 22, and is used to discharge the discharge end of the waste suction wheel 50 after cutting the battery. The waste side of the ear is collected by adsorption.

[0054] Among them, see Figure 6a with Figure 6b As shown, the waste suction wheel 50 is divided into a vacuum absorption area 501 , a vacuum breaking area 503 and a free area 502 along the radial section of the wheel;...

Abstract

The invention discloses a battery tab laser cutting device. The cutting device comprises a laser head (1), a passing roller assembly (2), a cutting supporting plate (3), a dust removal cover (4) and awaste discharging mechanism (5), wherein the passing roller assembly comprises a feeding roller (21) and a discharging roller (22), the cutting supporting plate (3) is arranged between the feeding roller (21) and the discharging roller (22), a cutting opening (31) is formed in the cutting supporting plate (3), the cutting opening (31) is located on a light emitting light path of the laser head (1), the inlet end of the dust removal cover (4) is arranged at the cutting opening (31), and the waste discharging mechanism (5) is arranged at the discharging end of the cutting supporting plate (3).According to the cutting device, battery tabs can be effectively and accurately cut, the cutting process is stable, meanwhile, dust removal and wrinkle prevention can be effectively achieved, and potential safety hazards can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of battery tab cutting equipment, in particular to a battery tab laser cutting device. Background technique [0002] Due to the many advantages of lithium batteries and their unique performance advantages such as high working voltage, high energy density and long cycle life, lithium batteries are widely used in consumer electronics such as electronic instruments, mobile phones, notebook computers, digital and home appliances. The large-scale application of lithium batteries in rapidly growing consumer electronics and other electronic products has greatly promoted the expansion of the lithium battery industry. higher. In lithium batteries, battery tabs are particularly important as electron output channels. [0003] During the preparation process, the battery tab needs to be cut into a suitable shape and then pasted and installed on the lithium battery. Among them, in the cutting process of battery tabs, t...
