Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a thermal ironing device for battery insulating films. Background Art

[0002] At present, in order to protect the battery surface, an insulating film is usually coated on the battery surface. The insulating film is used to prevent the external environment from damaging the battery, such as scratching, collision, etc. In order to ensure that the insulating film can fit and wrap the connection between the top of the battery and the side of the battery, usually, the side of the battery is completely wrapped with the cut insulating film, and the insulating film is set higher than the top of the battery. Then, a thermal ironing device for battery insulating films is used to bend and fit the insulating film set higher than the top of the battery on the top of the battery, and at the same time, thermal ironing and pressing are performed to realize that the insulating film is tightly attached to the top of the battery.

[0003] In the prior art, most thermal ironing devices for battery insulating films, as Figure 1 shown, include a battery top finishing block 111, two insulating film long side folding mechanisms 112, and two insulating film short side folding mechanisms 113. Usually, heating rods and thermocouples are arranged in the rubber-coated plates of the long side folding mechanism 112 and the short side folding mechanism 113, so that the rubber-coated plates can thermally iron and press the insulating film on the top of the battery while folding the insulating film.

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0049] Embodiment 1:

[0050] This embodiment provides a heat ironing device for battery insulating film, including:

[0051] Base 1;

[0052] Moving bracket 2, which is movably arranged on base 1 along the first direction X;

[0053] First driving mechanism 3, which is installed on base 1 and used to drive moving bracket 2 to move;

[0054] Heat ironing mechanism 4, which is movably arranged on base 1 along the first direction X and used to heat iron the battery top;

[0055] The second driving mechanism 5 is installed on the base 1 and is used to drive the hot stamping mechanism 4 to move;

[0056] Two first hemming mechanisms 6 are installed on the moving bracket 2 and are used to hem the insulating film at the top of the battery along the second direction Z;

[0057] Two second hemming mechanisms 7 are installed on the moving bracket 2 and are used to hem the insulating film at the top of the battery along the third direction Y.

[0058] In this technical solution, the first driving mechanism 3 and the second driving mechanism 5 can be cylinders. When the battery insulating film hot stamping device works, first use a fixing device (not shown in the attached drawings of the specification) to fix the battery to be hot stamped and encapsulated, and the top of the battery is arranged opposite to the battery insulating film hot stamping device. Then, the second driving mechanism 5 controls the hot stamping mechanism 4 to move along the first direction X. The hot stamping mechanism 4 contacts the top of the battery and preheats the entire top surface for one second. After the preheating ends, the second driving mechanism 5 controls the hot stamping mechanism 4 to retract.

[0059] Then, the first driving mechanism 3 drives the moving bracket 2 to move along the first direction X. After the moving bracket 2 moves to the specified position, the two first hemming mechanisms 6 bend and paste the long sides of the insulating film at the top of the battery on the battery top cover, and the two second hemming mechanisms 7 bend and paste the short sides of the insulating film at the top of the battery on the battery top cover. After the hemming work is completed, the first driving mechanism 3 drives the moving bracket 2 to retract along the first direction X.

[0060] Finally, the second driving mechanism 5 controls the hot stamping mechanism 4 to move along the first direction X again to contact the top of the battery, and the hot stamping mechanism 4 performs hot stamping and pressing on the insulating film pasted on the battery top cover, so that the insulating film is closely attached to the battery top cover.

[0061] To sum up, the battery insulating film hot stamping device sets a separate hot stamping mechanism 4 to first preheat the entire top surface of the battery. Then, the first hemming mechanism 6 and the second hemming mechanism 7 bend the insulating film at the top of the battery, so that the insulating film can be closely attached to the preheated top of the battery. Finally, the hot stamping mechanism 4 is used to hot stamp and press the insulating film on the top of the battery, thereby effectively avoiding quality problems such as the insulating film being warped caused by the hemming not being in place or the pressing force being insufficient.

[0062] In addition, through this structural design, the hot stamping mechanism 4 can heat the entire top surface of the battery, which not only effectively improves the hot stamping effect and makes the quality of the produced products better; at the same time, it also makes it unnecessary to set heating rods and thermocouples on the first hemming mechanism 6 and the second hemming mechanism 7, greatly saving the use cost and maintenance cost, and having higher economic benefits.

Avoidance grooves 44 adapted to the structures of the pole post and the explosion-proof valve are respectively provided on the end face of the positioning press block 42 in contact with the battery. Through this structural design, the positioning press block 42 can be completely attached to the top of the battery, realizing a comprehensive thermal ironing treatment of the top of the battery, and making the insulation film fit more closely to the top of the battery.

[0071] Furthermore, the thermal ironing mechanism 4 further includes a heat insulation backing plate 45, which is arranged between the positioning press block 42 and the push plate 41.
