Description
Technical Field
The invention relates to the technical field of energy storage element manufacturing, in particular to a button type energy storage element sealing ring nesting tool.
Background
The packaging parts of button type energy storage elements such as button type batteries, button type super capacitors and the like comprise a positive electrode shell, a negative electrode cover and a sealing ring. The packaging process is that the sealing ring is nested on the negative electrode cover, then the positive electrode shell is buckled with the negative electrode cover, and finally the sealing machine is used for sealing.
In the early stage of button energy storage element manufacturing, in order to save the nesting procedure of the sealing ring, accessory manufacturers can injection-mold the sealing ring onto the negative electrode cover in advance, so that the integration of the negative electrode cover and the sealing ring is realized. Therefore, the process of nesting the sealing ring is omitted, and the sealing ring is firmly contacted with the negative electrode cover. However, in actual production, after the electrode tab is assembled inside the negative electrode cap, it is subjected to a long-time high-temperature baking. If the sealing ring is baked together with the negative electrode cover for a long time at high temperature, the sealing ring is easy to deform, and liquid leakage occurs after sealing. And the aging of the sealing ring can be accelerated by long-time high-temperature baking. Therefore, in the post production of the button energy storage element, the positive electrode shell, the negative electrode cover and the sealing ring become three independent components, so that the sealing ring nesting becomes an indispensable process.
Because the radial dimensions of the cathode cover and the sealing ring are small and the height is low, the nesting of the sealing ring belongs to a fine operation. Although the difficulty of nesting the sealing ring by hands is low in a natural environment, the electrode plate in the negative electrode cover is baked before nesting the sealing ring, and moisture and oxygen in the air are not allowed to contact any more, so that the nesting process needs to be completed in the glove box. And once an operator wears the glove, the nesting process of the sealing ring becomes very difficult, because the sizes of the sealing ring and the negative electrode cover are very small, the sight of the nesting process is easily shielded by the glove, the nesting operation is extremely difficult, and the finger part of the glove in the nesting process also easily touches the electrode plate, so that the electrode plate is polluted. There is therefore an urgent need for a tool to achieve quick, accurate and highly reliable nesting of seal rings.
Disclosure of Invention
The invention provides a button type energy storage element sealing ring nesting tool for solving the problems.
The technical scheme of the invention is as follows: a button type energy storage element sealing ring nesting tool comprises a positioner, a pressing ring pipe and a guide ring column from outside to inside. The locator comprises a negative electrode cover locating groove, a sealing ring locating groove and a pressing ring pipe locating hole.
The positioner is used for positioning the negative electrode cover, the sealing ring and the pressing ring pipe, so that the centers of the negative electrode cover, the sealing ring and the pressing ring pipe are aligned and the nesting process does not generate horizontal offset.
The negative electrode cover positioning groove, the sealing ring positioning groove and the pressing ring pipe positioning hole are respectively used for positioning the negative electrode cover, the sealing ring and the pressing ring pipe.
The guide ring column is used for guiding the sealing ring to the bottom of the positioner and preventing the sealing ring from overturning in the falling process. Because the grooved side of the seal ring must be facing downward when the seal ring is nested, it cannot be nested if a flip occurs. Meanwhile, the guide ring column can also press the negative electrode cover in the process of pressing the sealing ring by the pressing ring pipe, so that the negative electrode cover is prevented from moving.
The diameter of the guide ring column is more than 80% of the diameter of the bottom of the negative electrode cover, but is smaller than the diameter of the bottom of the negative electrode cover. The larger the diameter of the guide ring column is, the easier the guide ring column presses the negative electrode cover in the nesting process of the sealing ring, so that the negative electrode cover is prevented from shifting, but the diameter of the guide ring column is not suitable to exceed the diameter of the bottom of the negative electrode cover.
The length of the guide ring column is larger than that of the pressing ring pipe, so that a hand can hold the guide ring column from the upper part when the pressing ring pipe presses the sealing ring.
The negative electrode cover positioning groove is attached to the outer surfaces of the bottom and the shoulder of the negative electrode cover, so that the negative electrode cover can be accurately positioned.
The outer diameter of the pressing ring pipe is equal to the outer diameter of the sealing ring and is equal to the diameter of the pressing ring pipe positioner hole. Therefore, the pressing ring pipe can be positioned, and the sealing ring can be effectively nested.
The inner diameter of the pressing ring pipe is equal to the diameter of the guide ring column, so that the guide ring column can better press the negative electrode cover at the bottom in the process of pressing down the sealing ring for nesting.
The invention has the advantages that: the glove box can effectively solve the problems that when the sealing ring is nested in the glove box, the manual direct nesting operation is difficult and the efficiency is low after the glove is worn. Meanwhile, the electrode plate pollution caused by the fact that the glove touches the electrode plate when no nesting tool is directly operated manually can be avoided. The tool is used for nesting, and has the advantages of accurate positioning, high nesting efficiency, high reliability and high consistency.
