Abstract
The invention discloses a method for repairing a loosened copper core pole. The method comprises the following steps: (1) stripping off glue water at the periphery of a pole to expose a lead base by 8-10 mm; putting the welding head of electric soldering iron with the power of 500 W to 800 W into the bottom of a copper core threaded hole, heating a copper core, adding a tin wire to the lead base exposed at the periphery of the pole until the copper core is combined with the lead base, and taking out the electric soldering iron; (2) detecting a twisting force and detecting the copper core temperature by current, wherein the twisting force and the copper core temperature meet the requirements; (3) applying pole sealing glue and a coloring agent. According to the method, the operation is carried out by an existing conventional tool, the repair process is quick, the quality is reliable, the pole does not need to be disassembled and re-assembled, a repaired battery can be sold as a secondary battery, the waste of production cost of enterprises is greatly reduced, and the enterprise benefits are increased.
Description
Technical field
the present invention relates to storage battery 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 in order to most employing attractive in appearance, and pole is formed by tin-coated copper core lead base of casting.Although now casting pole technical merit is ripe, also there will be copper core and lead base in conjunction with bad phenomenon, influencing factor is a lot, as the preheating etc. of the control of: mold temperature, alloy flowability, copper core.The stealthy risk existed is difficult to be found in the fabrication process, until just there will be terminal heating sparking when client uses to wait harmful effect, be all cause, after these batteries are return because copper core and lead base loose contact loosen, can only dissect and re-assembly, then be used as out battery maintenance use of selling goods.Because pole loosens the value that problem greatly reduces 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 loosening copper core electrode post repair method, fast easy to maintenance, and reliable in quality re-assemblies without the need to dissecting, and the battery after reprocessing can be made secondary battery and sell, and greatly reduces 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, requires bottom the degree of depth to screwed hole, electric iron power 500W-800W, copper core is heated, the lead base that pole one week is exposed adds solder stick, until copper core and lead base combine, taking-up electric iron;
(2) detect torsion, current detecting copper core temperature, reach requirement;
(3) electrode column sealing glue and coloring agent is 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.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, and dissected without the need to picture in the past and re-assembly, the battery after reprocessing can be made secondary battery and sell, and greatly reduces the waste of enterprise's production cost, increases the performance of enterprises.
Accompanying drawing explanation
Fig. 1 is the present invention's structure cutaway view when reprocessing.
Embodiment
As shown in Figure 1, described middle cover 1 is provided with pole column hole 11, has the pole 2 of cooperation in pole column hole, is provided with the sealing ring 21 of cooperation thereon, is provided with sealing ring glue 12 at pole column hole simultaneously; 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 bottom the degree of depth to screwed hole, electric iron power 500W-800W, electric soldering iron tip diameter is less than copper core screwed hole 0.5-1mm, copper core is heated, the lead base that pole one week is exposed adds solder stick 3, until copper core and lead base combine, takes out electric iron;
(2) torsion is detected: if M8 moment of torsion is qualified higher than 20NM; Checking of great current copper core temperature: 3C heavy-current discharge 3min, detecting copper core temperature is not qualified higher than 40 DEG C;
(3) electrode column sealing glue and coloring agent is stamped.
Claims (4)
1. a loosening copper core electrode post repair method, is characterized 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, requires bottom the degree of depth to screwed hole, electric iron power 500W-800W, copper core is heated, the lead base that pole one week is exposed adds solder stick, until copper core and lead base combine, taking-up electric iron;
(2) detect torsion, current detecting copper core temperature, reach requirement;
(3) electrode column sealing glue and coloring agent is stamped.
2. one according to claim 1 loosens copper core electrode post repair method, it is characterized 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 characterized 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 characterized in that: in described step (2), current detecting is checking of great current.
