Abstract
The invention discloses a kind of loosening copper core electrode post repair method, step includes: the glue around pole is dug and opens by (1), makes lead base expose 8-10mm；Electric soldering iron tip is placed in copper core screwed hole, it is desirable to the degree of depth to screwed hole, electric cautery power 500W-800W, copper core is heated, one week exposed lead base of pole adds solder stick, until copper core and lead base combine, taking-up electric cautery；(2) detection torsion, current detecting copper core temperature, reaches requirement；(3) electrode column sealing glue and coloring agent are stamped.The present invention adopts existing conventional tool to operate, and method for maintaining is quick, reliable in quality, it is not necessary to re-assemblied as dissecting in the past, and the battery after reprocessing can be made secondary battery and sell, and is substantially reduced the waste of enterprise's production cost, increases the performance of enterprises.
Description
Technical field
The present invention relates to accumulator field, be specifically related to a kind of loosening copper core electrode post repair method.
Background technology
Current accumulator of electric car pole directly goes out formula for most employing attractive in appearance, and pole is formed by tin plating copper core casting lead base.Although now casting pole technical merit is ripe, but also there will be copper core and lead base in conjunction with bad phenomenon, influence factor is a lot, as: the control of mold temperature, alloy flowability, copper core preheating etc..The stealthy risk existed is difficult to be found in the fabrication process, until client just there will be the harmful effects such as terminal heating sparking when using, it is all cause owing to copper core and lead base loose contact loosen, after these batteries are return, can only dissect and re-assembly, be then used as out selling goods and safeguard that battery uses.Because pole loosens problem greatly reduces the value of battery, cause the significant wastage of cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of copper core electrode post repair method that loosens, easy to maintenance fast, reliable in quality, it is not necessary to dissect and re-assembly, the battery after reprocessing can be made secondary battery and sell, and is substantially reduced the waste of enterprise's production cost.
The present invention is achieved through the following technical solutions:
A kind of loosening copper core electrode post repair method,
(1) the glue plane around pole is opened, make lead base expose 8-10mm；Electric soldering iron tip is placed in copper core screwed hole, it is desirable to the degree of depth to screwed hole, electric cautery power 500W-800W, copper core is heated, one week exposed lead base of pole adds solder stick, until copper core and lead base combine, taking-up electric cautery；
(2) detection torsion, current detecting copper core temperature, reaches requirement；
(3) electrode column sealing glue and coloring agent are stamped.
The further improvement project of the present invention is, the glue plane around pole is opened convenient and swift by described step (1) reamer, and efficiency is high.
The present invention further improvement project is, described electric soldering iron tip diameter is less than copper core screwed hole internal diameter 0.5-1mm.Heat transfer welding effect is good.
The present invention further improvement project is, in described step (2), current detecting is checking of great current.The detection time is short, and testing result is reliable.
The present invention compared with prior art, has following obvious advantage:
The present invention adopts existing conventional tool to operate, and method for maintaining is quick, reliable in quality, it is not necessary to re-assemblied as dissecting in the past, and the battery after reprocessing can be made secondary battery and sell, and is substantially reduced the waste of enterprise's production cost, increases the performance of enterprises.
Accompanying drawing explanation
Fig. 1 is present invention structure sectional view when reprocessing.
Detailed description of the invention
As it is shown in figure 1, described middle cover 1 is provided with pole column hole 11, in pole column hole, there is the pole 2 of cooperation, be provided with the sealing ring 21 of cooperation thereon, be simultaneously provided with sealing ring glue 12 at pole column hole；Described pole 2 is made up of copper core 22 lead-sheathing base 23, and copper core and lead base loose contact cause loosening.
Repair process:
1) with reamer, the glue plane around pole is opened, make lead base expose 8-10mm；Electric soldering iron tip 4 is placed in copper core screwed hole, require that the degree of depth is to screwed hole, electric cautery power 500W-800W, electric soldering iron tip diameter is less than copper core screwed hole 0.5-1mm, copper core is heated, one week exposed lead base of pole adds solder stick 3, until copper core and lead base combine, takes out electric cautery；
(2) detection torsion: as M8 moment of torsion higher than 20N M be qualified;Checking of great current copper core temperature: 3C heavy-current discharge 3min, detection copper core temperature is qualified not higher than 40 DEG C；
(3) electrode column sealing glue and coloring agent are stamped.
Claims (4)
1. a loosening copper core electrode post repair method, it is characterised in that:
(1) the glue plane around pole is opened, make lead base expose 8-10mm；Electric soldering iron tip is placed in copper core screwed hole, it is desirable to the degree of depth to screwed hole, electric cautery power 500W-800W, copper core is heated, one week exposed lead base of pole adds solder stick, until copper core and lead base combine, taking-up electric cautery；
(2) detection torsion, current detecting copper core temperature, reaches requirement；
(3) electrode column sealing glue and coloring agent are stamped.
2. one according to claim 1 loosens copper core electrode post repair method, it is characterised in that: the glue plane around pole is opened by described step (1) reamer.
3. one according to claim 1 loosens copper core electrode post repair method, it is characterised in that: described electric soldering iron tip diameter is less than copper core screwed hole internal diameter 0.5-1mm.
4. one according to claim 1 loosens copper core electrode post repair method, it is characterised in that: in described step (2), current detecting is checking of great current.
