Description

Nylon spraying system for leading-out end of pole lug of battery pole piece

Technical Field

The utility model relates to a battery pole piece utmost point ear draws forth end spraying nylon system.

Background

In the production of the nickel-metal hydride battery, in the assembly process, in order to ensure that the tab leading-out end does not contact with the top end of the electrode group to cause the short circuit of the battery, the process requirement is that a nylon surface pad is placed through the tab at the top end of the electrode group to block the risk that the tab leading-out end contacts with the top end of the electrode group to cause the short circuit. On the other hand, the problem that the positive pole of the pole group is leaned on or the positive pole is misplaced can occur in the assembly process of the battery, and the surface pad can also reduce the risk that the pole lug leading-out end contacts the inner wall of the steel shell to cause the short circuit of the battery to a certain extent. But at present place the face pad at utmost point group top and hardly realize automated operation, place the face pad at utmost point group top through the staff one by one at present, waste time and energy, still often can lead to producing defective products or scrap article in the process later because the face pad is not in place placed, and sometimes also when the pressure block lid appears, the face pad dislocation does not play corresponding separation effect, causes the battery to appear short circuit scheduling problem at the customer end at last to influence the battery quality. Therefore, it is currently an research direction to seek another way to replace the cushion, thereby eliminating the cushion placing process.

Furthermore, a flow meter is arranged on a liquid inlet pipe or/and a liquid spraying pipe of the spraying device.

The utility model discloses a battery pole piece utmost point ear draws forth end spraying nylon system, simple structure, arrange rationally, convenient operation, draw forth battery pole piece utmost point ear the feed end of the conveyer belt of end spraying nylon system and link up mutually with the ejection of compact end of pasting the adhesive tape process, draw forth battery pole piece utmost point ear the discharge end of the conveyer belt of end spraying nylon system and link up mutually with the feed end of material collecting device or softening process, pole piece accessible conveyer belt automatic conveying can realize automatic assembly line production better. Use the utility model discloses a pole piece of battery pole piece utmost point ear leading-out end spraying nylon system spraying nylon can directly carry out the die-cut process continuous production after convoluteing, need not consume a large amount of manpowers to accomplish and put the face and fill up the process and can cancel and put the face and fill up the process, can reduce the cost of labor, improve production efficiency, can solve line balance problem simultaneously, improve the production qualification rate.

Drawings

Fig. 1 is a schematic frame diagram of a system for spraying nylon on the tab leading-out end of the battery pole piece in example 1.

Detailed Description

The embodiment is only for illustrating one implementation of the present invention, and is not to be taken as a limiting illustration of the protection scope of the present invention.

Example 1

A system for spraying nylon on the leading-out end of a pole ear of a battery pole piece comprises a hot melting furnace 1, a spraying device 2, a cooling bin 3 and a conveyor belt 4, wherein the spraying device 2 is provided with a liquid inlet pipe and two liquid spraying pipes, the end heads of the liquid spraying pipes are provided with nozzles (the liquid inlet pipe, the liquid spraying pipe and the nozzles of the spraying device are shown in the figure), the liquid inlet pipe of the spraying device, all be provided with the flowmeter on the hydrojet (for showing the flowmeter in the picture), hot melt furnace 1, spraying device 2 sets gradually in one side of conveyer belt 4 and hot melt furnace 1 is close to the feed end of conveyer belt 4, the drain pipe of hot melt furnace 1 is linked together with spraying device 2's feed liquor pipe, two hydrojet pipes of spraying device 2 set up the corresponding face of drawing forth the end just to the pole piece utmost point ear in conveyer belt 4's both sides and hydrojet pipe's nozzle with the mode that the nozzle is just right mutually, cooling bin 3 sets up the discharge end at spraying device 2's rear and conveyer belt 4 and runs through supercooling bin 3.

When the spraying device is used, a nylon material is firstly put into the hot melting furnace, liquid flows into the spraying device for standby after the nylon material is melted into liquid, the pole piece pasted with the adhesive tape vertically enters the conveying belt in a mode that the pole lug faces upwards, when the pole piece is conveyed to the nozzle of the liquid spraying pipe of the spraying device, the nozzle of the liquid spraying pipe of the spraying device starts spraying work, then the pole piece passes through the cooling bin along with the conveying of the conveying belt, the nylon sprayed on the two surfaces of the pole piece pole lug leading-out end in the cooling bin is cooled and solidified, and finally the pole piece flows out from the discharging end of the conveying belt to the material receiving device or the feeding end of a softening process, so that the nylon spraying work of the two surfaces of. In actual production, the feeding end of the conveyor belt of the nylon system sprayed on the leading-out end of the battery pole piece can be connected with the discharging end of the adhesive tape pasting process, and the discharging end of the conveyor belt of the nylon system sprayed on the leading-out end of the battery pole piece is connected with the feeding end of the material receiving device or the softening process, so that automatic flow line production of pole pieces is realized.
