Abstract

The utility model discloses a lithium battery heat pressing packaging device, which comprises a frame, a lifting boosting air cylinder, a male mould, a female mould and a lower template; wherein the lithium battery heat pressing packaging device also comprises a plurality of plane pressure air cylinders and a feed boosting air cylinder; each plane pressure air cylinder is used for supporting the lower template; while the feed boosting air cylinder is arranged below the frame and is connected with the male module; the male module penetrates the lower template and is controlled to move up and down by the feed boosting air cylinder; and the four corners of the female mould are sleeved on guide poles arranged at the four corners of the lower template. The device adopts the plane pressure air cylinder for supporting the lower template, which is convenient for adjusting the pressure balance of the lower template and can adjust the balance automatically, so as to ensure the planarity of the lower template. The male mould is arranged at the lower part for feeding and drawing actively and independently; the male mould which is not normally designed can not be adjusted due to overlarge pressure as an upper template needs to overcome a spring tension, so as to ensure that the surface of a packaged product after being packaged does not have cracks and corrugation, thereby improving the product quality; moreover, the male mould and the female mould are respectively controlled to move simultaneously by an independent air cylinder, which can shorten the heat pressing demoulding and spotting time, thereby effectively improving the production efficiency.

Description

Lithium battery packaging by hot pressing equipment

Technical field

The utility model is about a kind of lithium battery packaging by hot pressing equipment.

Background technology

In light weight, advantages such as capacity big, memory-less effect that lithium battery has, thereby obtained widespread usage, present many digital equipments have all adopted lithium battery to make power supply.The energy density of lithium ion battery is very high, and its capacity is with the 1.5-2 of the Ni-MH battery of weight doubly, and has very low self-discharge rate; In addition, almost not have " memory effect " and do not contain advantages such as Toxic matter also be the major reason of its extensive use to lithium battery.

At present, the employed lithium battery volume of some particular field is bigger, and shape is comparatively special, when carrying out packaging by hot pressing, its equipment is to adopt punch to be moved down by the cylinder drive above board, cooperate and carry out packaging by hot pressing with the die on being fixed on board, and the mould bases of solid punch is to rely on spring to position steady that the maintenance punch moves, but the lithium battery of this equipment packages exists large-scale sheet stock fold to occur in drawing process and breaks, thereby influence the product package quality, it is as follows to trace it to its cause:

1, because punch moves and carries out the surface by spring pressure and compress, can't guarantee that rationally adjusting voluntarily of clamping pressure distribute;

2, fatigue appears in spring easily in long-term the use, and then deviation appears in the spring dynamics of each position of mould bases, also is the reason that causes encapsulation not good;

3, punch adopts upper cylinder directly to draw, and the excessive need of stroke overcome spring tension and cause pressure excessive unadjustable;

4, the punch actuating length is big, also can influence operating efficiency.

The utility model content

The purpose of this utility model provides a kind of lithium battery packaging by hot pressing and establishes, and it can will adjust the equalizing pressure of matched moulds, to improve package quality.

Be practical above-mentioned purpose, solution of the present utility model is:

A kind of lithium battery packaging by hot pressing equipment, it comprises frame, promotes pressurized cylinder, punch, die and lower bolster; It also comprises a plurality of applanation cylinders and feeding pressurized cylinder, each applanation cylinder supports lower bolster, and the feeding pressurized cylinder is arranged on the frame below and connects punch, punch passes lower bolster and is moved up and down by the scarce control of feeding supercharging gas; Four jiaos of places of die are nested with on the guide pillar that is positioned at four jiaos of lower bolsters.

Described die is the below that is fixed on cope match-plate pattern, and cope match-plate pattern is connected with the lifting pressurized cylinder, and the Si Jiaochu of cope match-plate pattern and die is provided with guide hole, is placed on respectively to be positioned on the last guide pillar that is provided with in four jiaos of places of lower bolster.

After adopting such scheme, lithium battery packaging by hot pressing equipment of the present utility model at first is to adopt applanation cylinder supports lower bolster, then is convenient to adjust the lower bolster pressure balance and can carries out balance adjustment automatically, guarantees the flatness of lower bolster; Adopt punch to draw in addition, be not subjected to the conventional design punch to cause pressure excessive unadjustable because of overcoming spring tension, guarantee encapsulating products encapsulation rear surface crack-free and fold, promote product quality at cope match-plate pattern in following and initiatively independent feeding; Moreover punch and die are moved simultaneously by Indivudual cylinder control respectively, can reduce the time of the hot pressing demoulding and matched moulds, effectively enhance productivity.

The specific embodiment

As shown in Figure 1, 2, lithium battery packaging by hot pressing equipment of the present utility model, it comprises that a frame 1, a cope match-plate pattern 2, a die 3, a lower bolster 4, a punch 5, promote and increase cylinder 6, a feeding pressurized cylinder 7 and a plurality of applanation cylinder 8.

Promote pressurized cylinder 6 and be arranged on board 1 top, it connects cope match-plate pattern 2, and die 3 is to be fixed on cope match-plate pattern 2 belows.

Feeding pressurized cylinder 7 is arranged on board 1 below, it connects punch 5, and a plurality of applanation cylinders 8 are set on board 1 support 11, each a plurality of applanation cylinder 8 is to hold lower bolster 4 peripheries, lower bolster 4 middle parts have the through hole 41 of advancing for punch 5, punch 5 moves up and down in this through hole 41, and promptly 4 pairs of punch 5 of this lower bolster have the function of a guide-localization, and lower bolster 4 has the effect of accepting die 3 equalizing pressures simultaneously.

Si Jiaochu at cope match-plate pattern 2 and die 3 is provided with guide hole, is placed on respectively to be positioned on the last guide pillar 9 that is provided with in 4 four jiaos of places of lower bolster, and 9 pairs of cope match-plate patterns 2 of this guide pillar and die 3 have the function of a guide-localization.

This equipment is when work, adjust the flatness that 8 pairs of lower bolsters of applanation cylinder 4 support in advance, cooperate shown in Figure 3, die 3 moves down by promoting pressurized cylinder 6 controls, meanwhile, feeding pressurized cylinder 7 control punch 5 move up, and punch 5, the mobile together matched moulds of die 4 can carry out packaging by hot pressing to lithium battery.

This shows that this sealed in unit at first is to adopt applanation cylinder 8 to support lower bolster 4, then is convenient to adjust lower bolster 4 pressure balances and can carries out balance adjustment automatically, guarantees the flatness of lower bolster 4; Adopt punch 5 to draw in addition, be not subjected to the conventional design punch to cause pressure excessive unadjustable because of overcoming spring tension, guarantee encapsulating products encapsulation rear surface crack-free and fold, promote product quality at cope match-plate pattern in following and initiatively independent feeding; Moreover being moved simultaneously by Indivudual cylinder control respectively of punch 5 and die 4 can reduce the time of the hot pressing demoulding and matched moulds, effectively enhances productivity.
