Detailed description of the invention
Below in conjunction with the Figure of description provided, description is made in preferred embodiment of the present utility model.
As shown in Figure 1, soft package lithium battery 2 includes a gasbag 21 and is positioned at a battery core (not shown) of gasbag 21, carry out the upper end open of soft package lithium battery 2 after fluid injection encapsulating for the first time, again soft package lithium battery 2 is melted into after encapsulation, the air extractor 1 that the waste gas of chemical conversion generation and unnecessary electrolyte use this utility model to provide extracts, and carries out second time and encapsulate after having extracted.Specifically, air extractor 1 be gasbag 21 is punctured a bleeding point after to carrying out evacuation in gasbag 21, this bleeding point first time packaging line and second time packaging line between.
With continued reference to Fig. 1, the air extractor 1 that this utility model provides includes a base plate 40, is located on base plate 40 and for clamping the positioning fixture 30 of soft package lithium battery 2, and is located on base plate 40 and lays respectively at the mounting post 50 of positioning fixture 30 both sides.Specifically, soft bag lithium ionic cell 2 after fluid injection chemical conversion is held in vertically on positioning fixture 30 and upwards manifests a part for gasbag, it is in particular the part of more than second time packaging line, one extraction sector 10 and a subordinate extraction sector 20 are respectively arranged in two mounting posts 50, and the bleeding point of gasbag 21 is just arranged by extraction sector 20 with subordinate extraction sector 20.
Extraction sector 10 and subordinate extraction sector 20 are described in detail below.
As shown in figs. 2 to 4, extraction sector 10 includes sucker 12, vacuum-pumping tube 14, pricker 16 and pricker drive mechanism 18.Vacuum-pumping tube 14 is hollow structure and includes the cavity 142 extended along its length, cavity 142 includes the first cavity 1422 being positioned at front end and is positioned at rear end and the second cavity 1424 connected with the first cavity 1422, and the internal diameter of the first cavity 1422 is less than the internal diameter of the second cavity 1424；Pricker drive mechanism 18 be sealingly arranged in the rear end of vacuum-pumping tube 14 and having stretch in the second cavity 1424, can an output shaft 182 of slide anteroposterior；Pricker 16 is placed in cavity 142, specifically, the front end of pricker 16 is placed in the first cavity 1422, the mounting blocks 162 that the one-body molded diameter in its rear end is big compared with the first cavity 1424, output shaft 182 is screw thread straight-bar structure, mounting blocks 162 is arranged accordingly to nut structure, makes the rear end of pricker 16 achieve a fixed connection with output shaft 182, thus pricker 16 can be in company with pricker drive mechanism 18 slide anteroposterior；Sucker 12 is in order to be adsorbed in the gasbag 21 of soft package lithium battery 2, it is sheathed on the front end of vacuum-pumping tube 14 back-end sealing of sucker 12 and is connected with the cavity 142 of vacuum-pumping tube 14, specifically, offer on sucker 12 one run through before and after sleeve joint hole 122, the hole wall of sleeve joint hole 122 caves inward and forms a slot 124, the front end tube wall convex of vacuum-pumping tube 14 is provided with an engaging rib 146, and engaging rib 146 is sticked in slot 124, thus be sealedly and fixedly connected sucker 12 and vacuum-pumping tube 14；Offering an evacuation hole 144 being connected with cavity 142 between the front end of vacuum-pumping tube 14 and rear end, specifically, evacuation hole 144 is connected with the first cavity 1422.
Especially, having gap between the inwall of pricker 16 and output shaft 182 and cavity 142, the setting in this gap does not affect evacuation hole 144 and sucker 12 or the connection of gasbag 21.When pricker 16 slides into front position, the extended sucker of pricker 16 12 and puncture gasbag 21.
As shown in Fig. 5～7, subordinate extraction sector 20 relatively extraction sector 10 is simple, it is not required to puncture the pricker 16 of gasbag 21 and drive the pricker drive mechanism 18 of pricker, it only includes subordinate sucker 22 and a subordinate vacuum-pumping tube 24, the through hole 242 of connection subordinate sucker 22 to vacuum system is offered in subordinate vacuum-pumping tube 24, specifically, through hole 242 is linearly arranged, and is communicated to sucker 12 with the vacuum system that will be located in above subordinate extraction sector 20.Subordinate sucker 22 is oppositely arranged with sucker 12, the bleeding point of common blanket gas pouch 21.Other structures of subordinate extraction sector 20 are similar with extraction sector 10, are not described in detail in this.
Additionally, air extractor 1 also includes driving extraction sector 10 and subordinate extraction sector 20 movable with the straight line driving mechanism 60 closer or far from gasbag 21, and the contiguous block 62 being connected between pricker drive mechanism 18 and straight line driving mechanism 60, contiguous block 62 is also arranged in subordinate drive mechanism 20, specifically, it is arranged between subordinate vacuum-pumping tube 24 and straight line driving mechanism 60.
Introducing the work process of this utility model air extractor below with reference to all accompanying drawings: under original state, extraction sector 10 and subordinate extraction sector 20 do not contact with gasbag 21；Start extraction sector 10 and the straight line driving mechanism 60 of subordinate extraction sector 20 the most simultaneously, extraction sector 10 and subordinate extraction sector 20 is driven to move towards the gasbag 21 between being located therein, make the sucker 12 of extraction sector 10 be adsorbed in the both sides of gasbag 21 the most over the ground with the subordinate sucker 22 of subordinate extraction sector 20, and formation is tightly connected；Starting the pricker drive mechanism 18 of extraction sector 10, its output shaft 182 drives pricker 16 forward slip to puncture gasbag 21, forms a bleeding point on gasbag 21；Afterwards, pricker drive mechanism 18 slides backward and drives pricker 16 to retreat in cavity 142；Start the vacuum system being connected with extraction sector 10 and subordinate extraction sector 20 simultaneously, gasbag is bled.Under bleeding point, carry out second time after completing to bleed encapsulate.
Compared with prior art, extraction sector 10 simple in construction of the present utility model, a pricker 16 is set in vacuum-pumping tube 14, gasbag 21 can be punctured thus communicated air bags bag 21 to vacuum system, air suction process is simple, vacuum foot, and pumping efficiency is high；The sucker 12 of air extractor 1 is oppositely arranged with subordinate sucker 22, gasbag 21 after puncturing not with extraneous contact, the mouth that punctures of gasbag 21 is sealed docking by sucker 12 and subordinate sucker 22, can will take away in the waste gas after chemical conversion and unnecessary electrolyte self-evacuating vacuum hole 144 and through hole 242 after opening vacuum system, the requirement to environment reduces.
Above disclosed only preferred embodiments of the present utility model, its effect is to facilitate those skilled in the art to understand and implement according to this, certainly the interest field of this utility model can not be limited with this, therefore the equivalent variations made according to this utility model claim, still falls within the scope that this utility model is contained.
