Description

Technical Field

[0001] The present invention relates to a production line for forming an aerogel heat insulation pad and a working method thereof, which are used for the forming production of aerogel heat insulation pads for power batteries in the new energy industry. Background Art

[0002] Aerogel has very good heat insulation performance and is currently the most efficient energy-saving heat insulation material. Since aerogel has a uniform and dense nano-porous and multi-level fractal pore structure, it can effectively prevent air convection, thereby reducing thermal radiation and heat conduction.

[0003] Currently, with the rapid development of the new energy industry, the safety requirements for power batteries are continuously increasing. Due to its excellent heat insulation performance, the aerogel heat insulation pad has become the first choice for lithium battery heat insulation materials. The aerogel heat insulation pad also has good compression performance. While providing heat insulation, it can also be used as a buffer material between battery cells to adapt to the expansion and contraction changes of battery cells during charging and discharging.

[0004] The market demand for aerogel heat insulation pads is huge, but the current production capacity cannot meet the demand. In addition, the current production process of aerogel heat insulation pads cannot be continuously and automatically produced, resulting in low production efficiency and high production energy consumption.

[0005] Chinese Patent No. 202320090735.2 discloses a forming device for producing an aerogel heat insulation pad. It pre-presses the aerogel core material with one side of the encapsulation film at low temperature through a first pre-pressing component to remove the air between the one-side encapsulation film and the aerogel core material, then turns over the aerogel core material with the one-side encapsulation film through a turning component, attaches the other-side encapsulation film, and then re-pre-presses the aerogel core material with both sides of the encapsulation film at low temperature through a second pre-pressing component, and finally performs high-temperature pressing through a

[0006] pressing component. By this method, the air between the encapsulation film and the aerogel core material can be effectively removed, reducing the generation of bubbles. However, the invention purpose of this forming device is to effectively remove the air between the encapsulation film and the aerogel core material through this device, reducing the generation of bubbles, and it does not disclose the specific forming production process of the aerogel heat insulation pad.

[0065] A working method of an aerogel heat insulation pad forming production line includes the following steps:

[0066] I. Canning.

[0067] The canning device 1 adopts the mode of a vertical filling machine. In the filling machine 1, aerogel powder is filled into the packaging film, and then the two sides of the packaging film are sealed to make the semi-finished product A of the aerogel heat insulation pad.

[0068] Since the aerogel powder has a small density and fine particle size, more air will be accompanied during filling. Therefore, a degassing screw is used during filling to improve the metering accuracy and control the powder from spreading.

[0069] II. Flanging.

[0070] When the semi-finished product A after filling and sealing is under pressure, the internal powder may leak from the sealed places on both sides of the packaging film, so the flanging operation needs to be carried out.

[0071] (1) The semi-finished product A after filling and sealing is grabbed by the first manipulator 101 from the canning device 1 and placed on the support plate 231 of the flanging mechanism 23. The two sealed sides of the semi-finished product A are respectively placed on the left and right support plates 231; the pressing plate driving mechanism 233 drives the pressing plate 232 to move down and press on the semi-finished product A, pressing down the semi-finished product A, and the two sealed sides of the semi-finished product A are turned up by 90°. The size of the semi-finished product A can be controlled by adjusting the gap between the two support plates 231.

[0072] (2) The manipulator 10 grabs the semi-finished product A from the support plate 231 and places it on the flanging device conveyor line 22. The flanging device conveyor line 22 transports the semi-finished product A to the gluing mechanism 24, and the gluing mechanism 24 automatically applies glue to the two sealed sides of the semi-finished product A.

[0073] (3)The in - process product A after gluing is continuously conveyed by the hemming device conveyor line 22. When passing through the guiding strip 25, the two - side seals of the in - process product A are folded inwards by 90° by the guiding strip 25, and the two - layer film edges at the folding position are fixed and sealed with glue, finally completing the 180° hemming work.

[0074] III. Cold pressing and degassing.

[0075] Although the in - process product A has undergone spiral degassing during filling, due to the characteristics of the aerogel powder itself, there is still a lot of air inside the in - process product A, and this part of the excess air needs to be extruded from the pores on the surface of the encapsulation film by pressing.

[0076] (1)The in - process product A after hemming is grabbed by the second manipulator 102 from the hemming device conveyor line 22 to the beating mechanism 31. The hammer driving mechanism drives the hammer to move, and the in - process product A is beaten with high - frequency and low - pressure to make the powder distribution inside the in - process product A uniform.

[0077] (2)The in - process product A after beating is conveyed by the cold - pressing degassing conveyor line 35. When passing through the extrusion roller path 32, the extrusion roller path 32 extrudes the air from the in - process product A, compressing the in - process product A to the required thickness; while extruding, the cold - pressing vibration mechanism 33 vibrates the cold - pressing degassing conveyor line 35, making the in - process product A vibrate with high frequency and low amplitude, so that the powder distribution inside the in - process product A is more uniform.

[0078] IV. The first palletizing device loads and palletizes.

[0079] The in - process product A after cold - pressing degassing needs to be quickly loaded onto the tray and pressed to prevent air from returning to the inside of the encapsulation film again.

[0080] (1)In the first palletizing device, the empty - tray transplanting mechanism 42 transplants the empty tooling pallet 10 in the empty - tray stacking mechanism 41 to the tray conveyor line 43, and the tray conveyor line 43 conveys this tooling pallet 10 forward.

[0081] (2)In the first palletizing device, the in - process product A after cold - pressing degassing is grabbed by the third manipulator 103 from the cold - pressing degassing conveyor line 35 to the tooling pallet 10 on the tray conveyor line 43. After a tray of the tooling pallet 10 is filled, the tray conveyor line 43 moves this tooling pallet 10 forward to the full - tray transplanting mechanism 44, and the full - tray transplanting mechanism 44 transplants this tooling pallet 10 to the full - tray stacking mechanism 46. The number of tooling pallets 10 is adjusted according to the production capacity rhythm for each stack.

[0082] V. Preheating.

[0083] The tooling tray 10 of the full - tray stacking mechanism 46 enters the heat - treatment conveyor line 8 and is conveyed by the heat - treatment conveyor line 8 to the pre - heating station of the heating and heat - preservation machine 6 for pre - heating first. To save energy, the pre - heating station of the heating and heat - preservation machine 6 uses the waste heat of the cooling station to pre - heat the in - process product A.

[0084] The encapsulation film of the in - process product A will soften when heated, and applying external vibration can make the internal powder distribution more uniform.

[0085] After being conveyed to the position, the lifting mechanism 51 lifts the tooling tray 10 off the heat - treatment conveyor line 8, and then under the action of the pre - heating vibration mechanism 52, the in - process product A vibrates, making the internal powder distribution of the in - process product A uniform. After reaching the set time, the lifting mechanism 51 drives the in - process product A to descend onto the conveyor belt and is conveyed to the next station.

[0086] VI. Heating and heat - preservation.

[0087] The in - process product A after two - time vibration pre - heating is conveyed by the heat - treatment conveyor line 8 to the heating station of the heating and heat - preservation machine 6 for heating up; after reaching the set temperature, it maintains the time required for heat preservation to make the internal voids of the encapsulation film completely deformed and closed by heat. The heating and heat - preservation machine 6 can use natural gas or electric heating.

[0088] VII. Cooling down.

[0089] The in - process product A that has completed heat preservation is sent by the heat - treatment conveyor line 8 to the cooling and cooling machine 7 for cooling down. The waste heat of the cooling and cooling machine 7 will be sent to the pre - heating station for reuse. The cooling method of the cooling and cooling machine 7 is air - cooling. When the in - process product A is cooled to room temperature, it is finally formed into an aerogel thermal insulation pad. After cooling, the deformation of the internal pores of the encapsulation film will be fixed, thus preventing air from entering again.

[0090] VIII. Unstacking and removing the tray by the second palletizing device.

[0091] (1) After the aerogel thermal insulation pad is cooled, it is sent to the exit together with the tooling tray 10 by the heat - treatment conveyor line 8, and then sent to the full - tray stacking mechanism 46 of the second palletizing device together with the tooling tray 10;

[0092] (2) In the second palletizing device, the full - tray transplanting mechanism 44 transplants the tooling tray 10 and the aerogel thermal insulation pad at the full - tray stacking mechanism 46 to the tray conveyor line 43, and the tray conveyor line 43 conveys the tooling tray 10 and the aerogel thermal insulation pad forward;

[0093] (3) The aerogel thermal insulation pad is grabbed from the tooling tray 10 of the tray conveyor line 43 by the fourth manipulator 104 and sent to the packaging device 9;

[0094] After the tooling tray of a set is unloaded, the tray conveyor line 43 moves the empty tooling tray 10 forward to the empty tray transfer mechanism 42, and the empty tray transfer mechanism 42 transfers the tooling tray 10 from the tray conveyor line 43 to the empty tray stacking mechanism 41; after the empty trays are stacked, they are sent to the loading and palletizing area by the AGV.

[0095] IX. Packaging.

[0096] The aerogel thermal insulation pad is placed on the packaging conveyor line 95 by the No. 4 manipulator 104, and successively passes through the labeling by the labeler 91, the outer packaging by the packaging machine 92, the outer packaging sealing by the sealing machine 93, and the boxing by the boxing machine 94, and finally the production is completed.
