Abstract

The utility model discloses a packaging device for a lithium-ion battery. The packaging device is characterized in that the lower end of an air cylinder is connected with an upper end socket by virtue of a piston plate, the corresponding lower end of the upper end socket is provided with a lower end socket, and one end of the lower end socket is connected with a shell groove mould; one end of the shell groove mould is connected with a pressure clip, and one end of the pressure clip is connected with a steel block; the lower end of the steel block is provided with a steel block air cylinder, and a piston shaft is sleeved on a piston plate. The packaging device provided by the utility model has the effects that the production efficiency of an operation process is doubled, the operating staff is reduced, the production equipment is saved, the production cost is saved, a condition that two groove shells are not neat because of uneven force is avoided, and the product quality is improved.

Description

A kind of packaging system for lithium ion battery

Technical field

The utility model relates to a kind of packaging system for lithium ion battery, relates in particular to a kind of device simultaneously encapsulating for lithium ion battery manufacturing process two closedtop limits.

Background technology

At present, existing industry polymer (Soft Roll) cylindrical battery shell is in two deep trouth housings, to place volume core to merge encapsulation aftershaping, after two deep trouth shells of existing industry merge, the process common practices of encapsulation is: it is single secondary transversely arranged adopting die head in packaging shell equipment, method of operation is: as shown in Figure 1, first, volume core is placed in two pot shells, both hands are clutched volume core and housing, the registration of visual two pot shells, by two pot shells fail overlap with hand floating whole after, region 1 on housing closedtop is encapsulated after being placed on Encapsulation Moulds head surface, on closedtop, region 1 has encapsulated, the second, after being placed on to Encapsulation Moulds head surface by closedtop lower area 2 after clutching, housing and volume core encapsulate.Its shortcoming is that artificial firmly uneven two pot shells that cause are uneven, and product quality is low, and production efficiency is not high.

Summary of the invention

The purpose of this utility model is to provide a kind of packaging system for lithium ion battery, and after this packaging system can merge cylindrical battery two deep trouth shells, left and right sides closedtop can encapsulate simultaneously, and it is uneven to stop two pot shells, improves the quality of products, and reduces quality cost.

The utility model is achieved like this, it comprises cylinder, the axis of the piston, upper cover, bottom head, formwork mould, bloom, bloom cylinder, pressure clamp and piston plate, it is characterized in that: cylinder lower end connects upper cover by piston plate, bottom head is installed in the corresponding lower end of upper cover, bottom head one end connects shell groove mould, shell groove mould one end Bonding pressure folder, and pressure clamp one end connects bloom, bloom lower end is provided with bloom cylinder, and piston sleeve is on piston plate.

Encapsulation process after repacking described in the utility model is as follows: (1) is placed on volume core in two pot shells, both hands are clutched volume core and housing, the registration of visual two pot shells, by two pot shells fail overlap with hand floating whole after, housing is placed in the pot shell mould on bloom surface, after pressure handle housing under pressure clamp being compressed, after (2) are pushed between two die heads by foot switch by pot shell mould, die head is pressed down housing both sides is exposed outside and need the side seal of encapsulation to encapsulate by air pressure again.

Effect of the present utility model is: improve the production efficiency of one times of this flow chart, reduce operating personnel, save production equipment, save company's production cost, stop artificial firmly uneven two pot shells that cause uneven, improve the quality of products.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the utility model is to come like this work and enforcement, it comprises cylinder 3, the axis of the piston 4, upper cover 5, bottom head 6, formwork mould 7, bloom 8, bloom cylinder 9, pressure clamp 10 and piston plate 11, it is characterized in that: cylinder 3 lower ends connect upper cover 5 by piston plate 11, bottom head 6 is installed in the corresponding lower end of upper cover 5, bottom head 6 one end connect shell groove mould 7, shell groove mould 7 one end Bonding pressure folders 10, pressure clamp 10 one end connect bloom 9, bloom 9 lower ends are provided with bloom cylinder 10, the axis of the piston 4 is enclosed within on piston plate 11.

It is as follows that the utility model has been reequiped rear encapsulation process:

(1) volume core is placed in two pot shells, both hands are clutched volume core and housing, the registration of visual two pot shells, by two pot shells fail overlap with hand floating whole after;

(2) housing is placed in shell groove mould 7, and will rolls up core and housing by pressure clamp 10 and compress;

(3) tramp with one's feet out the switch of bloom cylinder 9, shifts the shell groove mould 7 on bloom 8 onto bottom head 6 surfaces by air pressure;

(4) promote the shell groove mould 7 on bloom 8 surfaces to the time of bottom head 6 required use according to having debugged air pressure, the good bottom head of inner setting seals time of delay 6 times, arrive behind bottom head 6 surfaces Deng shell groove mould 7, upper cover 5 is subject to the pressure of cylinder, presses down with closedtop limit, the surperficial closed pair battery core housing of bottom head 6 both sides and encapsulates;

(5) by the control of internal timer, after certain hour to be packaged, upper cover 5 and bloom 8 are subject to cylinder control, and upper cover 5 will rise, and bloom 8 will exit to initial point;

(6) open pressure clamp 10 from the interior taking-up battery core of shell groove mould 7, encapsulation completes.
