Background technology
In lithium ion battery manufacturing, battery battery core needs the operation of battery core quantitatively being injected to electrolyte after entering shell, the required precision of inside battery reservoir quantity is very harsh, fluid injection too much can cause battery leakage and drum shell, and the problems such as battery capacity is not enough, internal resistance is bigger than normal, platform is low and cyclicity is poor are crossed that I haven't seen you for ages and caused in fluid injection.
In the injection process of lithium ion battery liquid injection machine, require very high to the vacuum leakproofness of filling machine, and whether the contact portion that the pressure difference that the quality of sealing and whole vacuum electrolyte filling device can bear depends primarily on seal head and workpiece can closely cooperate and the firm reliability of seal head self.
The sealing of existing filling machine mainly adopts the hermetically-sealed construction of blocked shot formula, but the connection of seal head and blocked shot is only adopt conventional air-tube type to connect, namely on blocked shot, a groove is added, seal head is allowed to be stuck on blocked shot, this connected mode is very unstable in a high voltage state, easily come off, thus easily cause the operating trouble of filling machine.
Existing filling machine fluid injection the reasons for the above problems are: the version of the connected mode of seal head and blocked shot and the seal head of employing and the material of use all can not meet lithium ion battery liquid injection stage more and more higher vacuum level requirement.
In view of this, necessaryly provide a kind of adaptive cavity seal head assembly, it can solve, and the seal head that lithium ion battery occurs in injection process easily comes off, the problem such as poorly sealed, thus the failure rate of injection process can be reduced to a great extent, promote the product quality in fluid injection stage.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and a kind of adaptive cavity seal head assembly is provided, it can solve, and the seal head that lithium ion battery occurs in injection process easily comes off, the problem such as poorly sealed, thus the failure rate of injection process can be reduced to a great extent, promote the product quality in fluid injection stage.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of adaptive cavity seal head assembly, comprise blocked shot and seal head, one end of described blocked shot is provided with screwed hole, and described seal head comprises connected head and bar portion, described bar portion is provided with the external screw thread coordinated with described screwed hole, and described bar portion is spirally connected with described blocked shot and is connected.
One as the utility model adaptive cavity seal head assembly is improved, and described head comprises master metal body and outer encapsulate portion, and described outer encapsulate portion is wrapped in outside described master metal body.
One as the utility model adaptive cavity seal head assembly is improved, and the diameter of described master metal body is greater than the diameter in described bar portion, and described master metal body and described bar portion one-body molded.
One as the utility model adaptive cavity seal head assembly is improved, described master metal body comprise the connecting portion that is connected with described bar portion and be not connected with described bar portion expose portion, what described master metal body was wrapped up in described outer encapsulate portion completely exposes portion.
One as the utility model adaptive cavity seal head assembly is improved, and described outer encapsulate portion is set to flexible non-metallic component.
One as the utility model adaptive cavity seal head assembly is improved, and described master metal body is set to stainless steel component.
One as the utility model adaptive cavity seal head assembly is improved, and the other end of described blocked shot is extended with projection.
During use, only need seal head to be tightened on blocked shot, during work, promoting blocked shot by drive unit, make it block seal, then extracting vacuum, when reaching required vacuum degree, then by drive unit, blocked shot being unclamped.
Relative to prior art, the utility model improves the fluid injection sealing device of existing filling machine version, changes thread connecting mode into, improve the high-voltage stability of seal head by existing groove fastening mode.And, during this use is novel, the composite construction of seal head both ensure that its reliability be connected with blocked shot, also ensure that the sealing coordinated of head and seal, thus realize the excellent sealing of fluid injection part, improve the endurance of single unit system to vacuum, allow priming device can bear larger negative pressure, thus reach better fluid injection effect, and then filling machine is allowed to develop into possibility to higher level vacuum.
