Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and in particular relates to a battery pack processing device for new energy vehicles. Background Art

[0002] Oil is a non-renewable resource. At the same time, after being mined and processed, oil can be used as a power source for cars. With the advancement of automobile technology, more and more people choose to travel by car, not only to save resources, but also to reduce the pollution of automobile exhaust emissions to the environment. People have invented new energy vehicles, which store electricity through lithium battery packs. New energy vehicles discharge electricity during driving to drive the car, which allows people to travel in a green way and also reduces people’s travel costs.

[0003] In the processing of battery packs for new energy vehicles, the application of thermal conductive adhesive is a very important step, which is mainly used to improve the heat transfer efficiency inside the battery module and ensure that the heat generated by the battery during operation can be effectively dissipated, thereby maintaining the optimal operating temperature of the battery, extending the service life, and improving safety. The existing method is to use an automatic glue dispensing machine to apply an S-shaped path on the bottom of the battery box, and then press the battery pack to form a thermal conductive adhesive layer between the bottom of the battery box and the battery. However, when applying thermal conductive adhesive in this way, the bubbles in the thermal conductive adhesive cannot be squeezed out. Instead, bubbles will form between the bottom of the battery box and the battery. The presence of bubbles will form insulation areas inside the thermal conductive adhesive. The thermal resistance of these areas is much higher than the thermal conductive adhesive itself, resulting in a decrease in the overall heat conduction efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a battery pack processing device for new energy vehicles to solve the problems raised in the above background technology.

Bevel gear one will drive meshing bevel gear two to rotate. Bevel gear two drives pulley two to rotate through a long rod. After passing through a subsequent transmission rod, the tamping rod will vibrate. Since the rear part of the tamping rod penetrates deep into the interior of the thermal conductive adhesive, the tamping rod will transmit the vibration to the interior of the thermal conductive adhesive, thereby concentrating the bubbles in the thermal conductive adhesive into large bubbles. After the vibrating tamping rod concentrates the bubbles into large bubbles, they are smeared on the bottom of the battery box.

When the distance between the lower surface of the connecting plate and the bottom surface of the battery box is the thickness of the thermal conductive adhesive, the pneumatic telescopic rod no longer extends and maintains its length. The hydraulic telescopic rod extends at a uniform speed according to the moving speed of the connecting seat, so that the push plate pushes the thermal insulation adhesive inside the barrel into the inside of the connecting seat, and finally flattens the adhesive to a uniform thickness on the bottom of the battery box, avoiding the generation of bubbles in the process of forming a thermal conductive adhesive layer by pressing the battery pack.

When the distance between the lower surface of the connecting plate 10 and the bottom surface of the battery box is the thickness of the thermal conductive adhesive, the pneumatic telescopic rod 17 no longer extends and maintains its length. The hydraulic telescopic rod 3 extends at a uniform speed according to the moving speed of the connecting seat 5, so that the push plate 4 pushes the thermal insulation adhesive inside the barrel 1 into the inside of the connecting seat 5, and finally flattens the uniform thickness of the adhesive on the bottom of the battery box, avoiding the generation of bubbles in the process of forming a thermal conductive adhesive layer by pressing the battery pack.

[0027] Working principle:

[0028] Before the present invention is used, the rectangular block 8 is completely located inside the chute 7, the electromagnet 6 adsorbs the permanent magnet 14 to make it in close contact with the connecting seat 5, the barrel cover 2 is removed and a proper amount of thermal conductive glue is added to the inside of the barrel 1, and then the barrel cover 2 is installed;

[0029] Before the present invention is used, the device is driven to move by an existing device, so that the bottom end of the connecting seat 5 contacts the bottom surface of the battery box and the left and right sides of the connecting seat 5 contact the side walls of the battery box, and then the electromagnet 6 is energized in the reverse direction to push the permanent magnet 14 and the partition 13 to slide along the moving groove 19 to enter the interior of the sliding cavity 12 until the partition 13 is limited by the limit block 11, and the pneumatic telescopic rod 17 is appropriately extended to drive the cover plate 18, the C-shaped plate 9, the rectangular block 8 and the connecting plate 10 to move downward along the slide groove 7. When the distance between the lower surface of the connecting plate 10 and the bottom surface of the battery box is the thickness of the thermal conductive adhesive, the pneumatic telescopic rod 17 no longer extends and maintains the length, and then the bidirectional motor 151 works to drive the main eccentric wheel 152 and the driving wheel 153 to rotate, and the driving wheel 153 will drive the pulley 156 to rotate through the driving belt 157, and the pulley 156 drives the bevel gear 158 to rotate through the transmission shaft 155, and the bevel gear 158 will The meshed bevel gear 159 is driven to rotate, and the bevel gear 159 drives the pulley 1511 to rotate through the long rod 1510. The pulley 1511 drives the front pulley 163 near the bidirectional motor 151 through the short belt 166. The front pulley 163 will drive the tamping rod 161, the secondary eccentric wheel 162 and the rear pulley 164 in the middle to rotate, and through the transmission of the rear belt 165, it will drive another rear pulley 164 to rotate, and this rear pulley 164 will drive The tamping rod 161, the secondary eccentric wheel 162 and the front pulley 163 in the middle rotate, and the front pulley 163 drives the front pulley 163, the tamping rod 161 and the secondary eccentric wheel 162 at the edge to rotate through the front belt 167. As the multiple secondary eccentric wheels 162 rotate, the tamping rod 161 will vibrate. As the rear part of the tamping rod 161 penetrates into the interior of the thermal conductive glue, the tamping rod 161 transmits the vibration to the interior of the thermal conductive glue, thereby concentrating the bubbles in the thermal conductive glue into large bubbles.

[0030] The connecting seat 5 is driven to move slowly and uniformly along the side wall of the battery box. At the same time, the hydraulic telescopic rod 3 is extended uniformly according to the moving speed of the connecting seat 5, so that the push plate 4 pushes the heat insulating glue inside the barrel 1 into the inside of the connecting seat 5. After the bubbles are concentrated into large bubbles by the vibrating tamping rod 161, they are smeared on the bottom of the battery box. As the main eccentric wheel 152 rotates, it will drive the connecting plate 10 to vibrate, so that the large bubbles will be discharged and the upper surface of the heat conductive glue will be leveled.

[0031] After the ground of the battery box is coated with a uniform thickness of thermal conductive glue, the hydraulic telescopic rod 3 will stop extending and the device will also stop moving. Then the pneumatic telescopic rod 17 will shorten, driving the C-shaped plate 9 and the connecting plate 10 to move up and reset. Then the electromagnet 6 will be energized in the forward direction to attract the permanent magnet 14 and the partition 13 to slide along the movable groove 19 until the permanent magnet 14 contacts the electromagnet 6, so that the thermal conductive glue is no longer in the connecting seat 5 but is discharged from the inside.
