Problems solved by technology

But this kind of feeding method, because the manipulator needs the response time and the time of back and forth action, it can’t be fed continuously, and the feeding speed is slow. For the continuous production film cutting equipment, it can’t meet the feeding requirements, which seriously affects the production efficiency.
[0005] In summary, the existing punching equipment has obvious defects, and it is urgent to provide an optimized pole piece punching equipment

Embodiment 1

[0035] Such as Figure 1 to Figure 10 As shown, a pole piece punching equipment includes a punching die 01 and a suction device 02 arranged at the discharge end of the punching die 01. The suction device 02 includes a mounting bracket 1 and is movably arranged on the mounting bracket 1. The first suction belt 2, the second suction belt 3 arranged above the first suction belt 2, the first driving device 4 for driving the first suction belt 2 and the second suction belt for driving The second driving device 5 for belt 3 feeding, the first suction belt 2 and the second suction belt 3 are provided with a number of suction holes, the first suction belt 2 is provided with a first suction assembly 6 inside, A second suction assembly 7 is arranged inside the second suction belt 3 , and the second suction assembly 7 is located at the discharge end of the first suction belt 2 .

[0036] Specifically, the first air suction assembly 6 suctions the first suction belt 2 on its upper side, ...

Embodiment 2

[0056] Such as Figures 11 to 13 As shown, the difference between the second embodiment and the first embodiment above is that the cutter includes a left cutting ear part 08 and a right cutting ear part 09 respectively arranged on both sides of the ear.

[0057] Such as Figure 12 As shown, the spacer waste 200 includes the cut material at the waste gap 040 on the left side of the tab and the waste gap 050 on the right side of the tab, and the shape of the left cut tab 08 corresponds to the shape of the waste gap 040 on the left side of the tab. , the shape of the right incisor ear 09 corresponds to the shape of the waste notch 050 on the right.

[0058] In this embodiment, the pole piece raw material 100 is fed in the form of gap coating, the pole piece raw material 100 is fed once, and the cutter is punched once to obtain one pole piece. The punching speed of the cutter is fast, and the dimensional accuracy of the punched pole piece is high.

Abstract

The invention relates to the technical field of battery pole piece machining devices, in particular to a pole piece punching device. The pole piece punching device comprises a punching die and a sucking and sending device arranged at the discharge end of the punching die. The sucking and sending device comprises an installation support, a first sucking and sending belt movably arranged on the installation support, a second sucking and sending belt arranged above the first sucking and sending belt, a first drive device used for driving the first sucking and sending belt to conduct feeding, and the second drive device used for driving the second sucking and sending belt to conduct feeding. The first sucking and sending belt and the second sucking and sending belt are each provided with a plurality of sucking holes. A first gas sucking assembly is arranged on the inner side of the first sucking and sending belt. A second gas sucking assembly is arranged on the inner side of the second sucking and sending belt. The second gas sucking assembly is located at the discharge end of the first sucking and sending belt. Polar piece raw materials are punched through one punching die to form products, the product shape accuracy is high, the first sucking and sending belt and the second sucking and sending belt are sucked and matched so that discharge can be conducted, products are continuously and rapidly discharged, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of battery pole piece processing equipment, in particular to a pole piece punching equipment. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] In the production process of the pole piece of lithium battery, it is necessary to punch the tab part of the battery, and then unload and pack the punched pole piece. The existing pole piece punching equipment us...
