The two rubber-covering mechanisms 8 work separately, and respectively paste tapes on both sides of the bottom of the battery.

Working principle and working process of the present utility model are:

When the mechanism of the utility model performs coating hot-melt operation on the lithium battery cell, the insulating film 1 is placed in the insulating film hopper, and two insulating film hoppers can be provided, which are respectively arranged at the feeding port of the insulating film feeding mechanism 4 On both sides, continuous production can be realized without stopping. The feeding of insulating film 1 is to use the manipulator to use the suction cup to absorb the insulating film 1 from the insulating film silo, the feeding cylinder 4-6 drives the top plate 4-7 to drive the positioning column 4-8 to move upward, and the positioning column 4-8 passes through the insulating film The positioning hole 1-1 on 1 is used to realize the positioning and fixing of the insulating film 1; the driving motor 4-1 drives the ball screw 4-2 to drive the sliding plate 4-4 to move along the slide rail 4-3 to the hot melt coating mechanism 7 At the notch 7-13 in the middle of the horizontal plate 7-12, the two ends of the insulating film 1 are positioned between the film-touching roller 7-23 and the horizontal plate 7-12, the film-touching device 7-2 works, and the film-touching cylinder 7 -21 drives the film-touching roller 7-23 to move down to make it touch the top of the insulating film 1, and then the film-touching motor 7-22 drives the two film-touching rollers 7-23 to rotate in opposite directions respectively, so that the insulating film 1 is placed on the horizontal plate 7- 12 overall flattening. Then the feeding cylinder 4-6 drives the top plate 4-7 to drive the positioning column 4-8 to move down, the positioning column 4-8 is separated from the positioning hole 1-1 in the insulating film 1, and the driving motor 4-1 drives the ball screw 4 -2 drives the slide plate 4-4 to reversely move to the initial position along the slide rail 4-3.

Put the battery cell between the separators 5-2 of the battery feeding mechanism 5 and transfer it to the discharge end, use the manipulator to clamp the top of the battery cell 2 on the conveyor belt 5-1, and then move it vertically to the hot melt Above the coating mechanism 7, the bottom end of the cell 2 is placed in the middle of the insulating film 1. At this time, the film pressing device 7-3 and the film folding device 7-5 work simultaneously, and the pressure in the two film pressing devices 7-3 The film cylinder 7-31 drives the film pressing roller 7-33 to move towards the middle and approaches; the film folding cylinder 7-51 in the two film folding device 7-5 drives the two film folding rollers 7-53 and the two L-shaped push plates 7-52 Move towards the middle and approach. The electric core 2 held by the manipulator moves downward together with the insulating film 1 and passes through the laminating roller 7-33, so that the two ends of the insulating film 1 are wrapped on both sides of the electric core 2 and are covered by the laminating roller 7. -33 is clamped, and then the manipulator returns to the initial position.

Next, the push cylinder 6 starts to move, and the push cylinder pushes down the cell 2 and the insulating film 1 to break away from the gripping roller 7-33 and move toward the folding roller 7-53. The insulating film 1 is clamped together by the two folding film rollers 7-53, and when its bottom end passes through the slot 7-54, the edges of the insulating film 1 located at the two ends of the cell 2 are moved from bottom to top by the slot 7-54. Fold in the middle to complete the film folding operation.

At this time, the hot-melt device 7-4 starts to act, and the T-shaped push plate 7-44 is driven by the clamping cylinder 7-41 to clamp the electric core and the insulating film, and then the hot-melt cylinder 7-42 drives the hot-melt head 7-43 Move forward and stretch out the hot melt groove 7-45 on the upper end of the T-shaped push plate 7-44, contact with the insulating film 1 so that the insulating film 1 is hot-melt welded on the cover plate 2-2, and form heat on the insulating film 1. Fusion welding printed 1-2.

At the same time, the two rubber-coating mechanisms 8 start to work, and the vertical rail 8-2 moves horizontally on the horizontal rail 8-1 with the adsorption block 8-7 to the bottom of the battery after the coating is hot-melted, and the rubber-coated vertical plate 8-3 Drive the rubber-coated horizontal plate 8-6 to move upward on the vertical rail 8-2, so that the adsorption block 8-7 is in contact with the bottom of the battery, and the rubber-coated roller 8-10 is located on the small side of the battery; it is set on the tape material roller 8-5 The adhesive tape 3 on the top is drawn on the adsorption block 8-7 by the tension roller 8-4. The sticky side of the adhesive tape 3 is on the top, and the end is on the rubberized roller 8-10. The insulating film 1 at the bottom of the battery sticks to each other. At this time, the rubber-covering rollers 8-10 are tangent to the bottom of the battery, which plays a role of stretching and smoothing the adhesive tape 3, so that the adhesive tape is tightly attached to the bottom of the battery. Rubber-covered cylinder 8-9 elongates and drives adsorption block 8-7 to move towards rubber-coated roller 8-10, making rubber-coated roller 8-10 close to the small side of the battery, and giving rubber-coated roller 8-10 an external force Make it rotate upwards, thereby the end of adhesive tape 3 is pasted tightly on the small side of the battery, and the glue-covering work has been completed so far.

Then the rubber-coated cylinder 8-9 shrinks and drives the adsorption block 8-7 to leave the rubber-coated roller 8-10 for a small distance, and no longer contacts with the small side of the battery. Because the adhesive tape 3 is still in a tensioned state, the rubber-covered cylinder 8-9 continues to shrink and drives the cutter 8-8 to stretch out the knife groove 8-71, and the cutter 8-8 cuts the adhesive tape 3 from below, and the end of the cut adhesive tape 3 has poles. A short distance will not be attached to the insulating film 1. This distance depends on the degree to which the rubber coating rollers 8-10 deviate from the side of the battery. By adjusting, the overall rubber coating effect will not be affected.

Finally, the pushing cylinder 6, the hot-melt device 7-4, the lamination device 7-3, the film folding device 7-5 and the encapsulation mechanism 8 all return to their original positions through the reverse movement of the respective cylinders, and the encapsulation The completed electric core falls between the partitions on the conveyor belt of the unloading mechanism 9 below, and the conveyor belt is transported to the back-stage process.

To sum up, the utility model can conveniently realize the continuous and high-efficiency coating of the battery cells, and the tight connection of each station can greatly improve the production efficiency, and has good operability and safety.

The above-mentioned embodiments are only described to the preferred implementation of the utility model, and are not limited to the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the utility model.
