Description

A kind of lithium-ion-power cell is joined sheet method for separating and device

Technical field

The invention provides a kind of lithium-ion-power cell and join the sheet method for separating, the present invention also further discloses the sorting unit of realizing this method, belongs to the battery production technical field.

Background technology

In battery industry was produced, the pole piece uniformity of battery directly influenced battery life, and that joins the thickness of sheet and capacity that weight directly influences battery and battery normally goes into shell.Present most battery production factory all requires the battery pole piece sorting process process of weighing for guaranteeing product quality.Sorting process with join the most manual works that just are called weighing-appliance of the blade technolgy process assorting room of weighing with electronics; The thickness of joining sheet with the electronic digital indicator measurement; Weigh sorting and join the quality of sheet and people's mood, muscle power, behavior state counts for much, thereby disturbed by artificial factor.

The pole piece sorting of lithium-ion-power cell and join the important step that the sheet operation is a battery production; Chemical properties such as capacity with tap density that directly determines electrokinetic cell and battery; Chinese patent CN200920094144 discloses a kind of weight fraction screening device of lithium ion power cell pole flakes; This sorting unit only can be realized the sorting requirement of weighing of lithium ion power cell pole flakes, but can't realize the thickness measurement online sorting requirement of pole piece, in joining the process of sheet, the thicker phenomenon that makes battery can't normally go into shell of sheet thickness occurs joining through regular meeting like this; And the pole piece thinner thickness, compacted density also can influence the electrical property performance of battery greatly.

This lithium-ion-power cell is joined the assorting room that the sheet sorting unit both can satisfy pole piece weight; Also can satisfy simultaneously the assorting room of pole piece thickness; Final can directly carry out the lamination operation and save the artificial sheet operation of joining through the qualified pole piece of screening; Mechanization degree height of the present invention can be joined sheet automatically, and it is true, accurately to join the sheet data, the stability that the present invention can improve the quality of products greatly, reduces raw-material consumption, reduces artificial disturbance factor and error that hand dipping causes; Also avoid manual work to join sheet the healthy of workman worked the mischief, improved product quality.

Summary of the invention

The purpose of this invention is to provide a kind of lithium-ion-power cell and join sheet sorting unit method, with remedy exist in the known technology can't accomplish the pole piece thickness measuring simultaneously, join the defective of sheet automatically.

The present invention further discloses lithium-ion-power cell and join the sheet sorting unit, be used to realize that lithium-ion-power cell joins the sheet sorting.

Lithium-ion-power cell of the present invention is joined sheet sorting unit method, and technical solution is following:

Lithium-ion-power cell is joined the sheet sorting unit, carries out the method for separating that lithium-ion-power cell is joined sheet, and key step is:

A) thickness and the weight parameter to pole piece presets, and the parameter that presets is deposited in the computer;

When B) pole piece passes through measuring thickness device on first conveyer belt; The thickness parameter of this pole piece writes down and puts in order and import computer to the data of thickness parameter automatically by measuring thickness device; When pole piece passes through weighing device on first conveyer belt; The weight parameter of this pole piece writes down and puts in order and import computer to the data of weight parameter automatically by weighing device, compares with the parameter that presets that stores in the computer;

C) meet the parameter that presets, qualified pole piece is directly joined in the charge chute of sheet through terminal final arrival of sorting band.

D) do not meet the parameter that presets, computer is sent to cylinder control and servomotor control device with instruction, with being placed in the corresponding magazine behind the non-compliant pole piece.

E) when the pole piece number of screening reaches parameter preset, sending chimes of doom immediately reminds the operative employee to take the screening operation that the pole piece continued for preparing is carried out pole piece away.

Realize that above-mentioned lithium-ion-power cell joins the device of sheet method for separating, it is characterized in that:

Two conveyer belts that are used to transmit lithium ion power cell pole flakes; First conveyer belt mainly act as the transmission pole piece; Below first conveyer belt, be provided with a weighing device; On just, put and be provided with a measuring thickness device; This weighing device and measuring thickness device be electrically connected to computer, second conveyer belt is used for the sorting pole piece for the sorting band, connects the charge chute of joining sheet at the end of sorting band; The sorting band just on put and be provided with the effect of two suction dishes and be respectively to filter out and be placed in the corresponding magazine after thickness does not meet standard or the non-compliant pole piece of weight; These two suction dishes are that the guiding cylinder is connected with computer with servomotor, after screening, is sent to thickness and all standard compliant pole piece of weight in the charge chute of joining sheet through the slide that connects material by guiding cylinder and the action of servomotor control suction dish; Computer is counted processing to the qualified pole piece of sorting, when the sheet number reaches parameter preset, sends chimes of doom immediately and reminds the operative employee to take the screening operation that the pole piece continued for preparing is carried out pole piece away.

Lithium-ion-power cell of the present invention is joined the sheet sorting unit, and concrete structure is following:
