Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to graphene coating production equipment. Background Art

[0002] Graphene coating is a thin layer of graphene coated on the surface of a material. Graphene is a two-dimensional lattice of carbon atoms with remarkable properties such as high mechanical strength, electrical conductivity and barrier effect. It is widely used in the fields of medicine, industry, electronics, military industry, metallurgy, vehicles, textile fabrics, chemicals, electricity, buildings, etc. Among them, carbon-coated aluminum foil is used as the current collector in lithium-ion batteries, and a layer of conductive carbon coating is coated on both surfaces of the current collector, which improves the adhesion between the electrode material and the current collector, the conductivity of the overall pole piece, and the resistance of the conductive current collector to electrolyte corrosion and high voltage.

[0003] When the current collector is producing a graphene coating, its production equipment is composed of multiple processing devices. For example: a Chinese patent with application number 202111172721.7 discloses a production equipment for a graphene-coated conductive current collector, including a spraying unit, the spraying unit includes: a slurry barrel; a stirrer, whose stirring rod extends into the slurry barrel; a conduit, one end of which is connected to the bottom of the slurry barrel, and the other end is connected to the electrostatic spray needle, and the electrostatic spray needle is arranged inside the shell.

[0004] Although the technical solution in the above patent document realizes the surface spraying treatment of the substrate acting as a current collector, it still has the following defects: the spraying structure in the device for spraying graphene materials is mostly fixed, and then if the graphene material needs to be regenerated or the substrate needs to be rearranged after use, the spraying of the graphene material will inevitably be suspended, and the regeneration of the graphene material or the rearrangement of the substrate requires a lot of time. The graphene material remaining inside the spraying structure after use can easily cause the spraying structure to be blocked, and then the spraying structure needs to be cleaned or replaced when it is used again, which is not only troublesome and increases the burden on the staff, but also further increases the use cost of the product and reduces its production efficiency; the substrate will be pre-cleaned before the graphene coating treatment, but the cleaned substrate will inevitably come into contact with impurities such as dust in the air after being transported and assembled to the equipment, and then when it is directly coated, it is easy to affect the adsorption effect of the graphene material and the substrate due to the presence of impurities such as dust.

[0021] By setting up a material guiding mechanism, substrates of similar width can be adaptively used, thereby improving the applicability of the product. When the material guiding mechanism is adjusted, the shielding parts on the corresponding spraying components in the spraying mechanism can be adjusted synchronously, so that the spraying components can be suitable for spraying processing of the current substrate, further improving the applicability of the product.

[0022] When the material guiding mechanism is adjusted, it can simultaneously drive multiple blocking components to stretch the blocking fabric, so as to block the redundant parts of the passages on both sides of the box, thereby reducing the impact of the odor generated by the graphene material on the staff and ensuring the safety of the working environment.

The feed holes provided above and below correspond to the spray assemblies 34 distributed above and below in the spray mechanism 3.

[0059] See also Figure 4-Figure 5 and Figure 13-Figure 15 In the embodiment of the present invention, the drying mechanism 6 is composed of a hot air structure 61 and an adjustment component 62. The hot air structure 61 includes a lower box body 611 arranged on the top shell wall of the carrier plate 13, and a plurality of heating rod bodies 613 for heating are linearly arranged on the bottom inner wall of the lower box body 611, and an upper box body 612 is installed on the top of the lower box body 611 by screws. Rectangular through grooves are symmetrically opened on the top shell wall of the upper box body 612, and an air guide component is arranged in each rectangular through groove. The setting of the air guide component can discharge the wind entering the lower box body 611 in a wind direction-adjustable manner.

[0060] The air guide assembly includes a plurality of air guide plates 614 linearly distributed in the rectangular through slot. A through slot is provided inside each air guide plate 614, a load shaft is provided in the through slot, two ends of the load shaft are respectively fixedly connected to the corresponding inner wall of the rectangular through slot, and a groove is provided on the bottom shell wall of each air guide plate 614, a round rod is provided in the groove.

[0061] A movable plate 615 is commonly connected between the multiple round rods, and support rods are installed at both ends of the movable plate 615, and the end of the support rod away from the movable plate 615 penetrates the corresponding side wall of the upper box body 612. The support rods arranged at both ends of the movable plate 615 can ensure the stability of the movement adjustment of the movable plate 615 after penetrating the corresponding side wall of the upper box body 612. The adjustment of the movable plate 615 can realize the angle adjustment of the multiple air guide plates 614 connected thereto.

[0062] The adjustment component 62 is composed of an outer groove cylinder 621 and a connecting rod 622. There are two outer groove cylinders 621, both of which are sleeved on the rightmost tube body 41, and the two outer groove cylinders 621 are respectively fixedly connected to the corresponding end walls of the corresponding heat-conducting cylinder 42 by screws.

The reverse adjustment of the corresponding air guide plates 614 in the two air guide components further expands the uniformity of the substrate drying.

[0063] See also Figure 2 and Figure 5 In the embodiment of the present invention, the gas delivery pipeline is composed of a main pipe, a branch pipe and a secondary pipe. Among them, the top end of the main pipe is installed on the rear end of the rightmost tube body 41 through a connector. The bottom end of the main pipe passes through the rear shell wall of the outer shell 11, and the branch pipe and the secondary pipe are both connected to the main pipe. Among them, the other end of the branch pipe also passes through the rear shell wall of the outer shell 11, and the end of the branch pipe is located directly above the end of the main pipe. The other end of the secondary pipe extends into the interior of the lower box body 611. The ends of the main pipe and the branch pipe correspond to the docking of the spray components 34 at the upper and lower positions in the spray mechanism 3 when they are in the non-working area, so as to realize the self-cleaning treatment of the spray components 34 by the airflow.

[0064] The working principle of the present invention is: when the substrate is subjected to graphene coating treatment, the material guide mechanism 2 is first fine-tuned according to the specifications of the substrate to be treated. The material guide mechanism 2 synthesizes the graphene material to be sprayed through the coating feeding unit during the fine-tuning process. When the material guide mechanism 2 is adjusted, the electric push rods 22 at the two sides are started by an external controller device, so that the output ends thereof perform synchronous telescopic movements, and then the spacing of the guide rails 21 symmetrically arranged in the front and rear is adjusted under the action of the corresponding movable rods 23, so that the spacing can be adapted to the corresponding substrate. When the guide rails 21 are adjusted in displacement, the blocking fabric 242 in the corresponding blocking assembly 24 is stretched so that the passage on the side wall of the housing 11 can be properly blocked. If the two guide rails 21 are adjusted to be away from each other at this time, the blocking fabric 242 in the corresponding blocking assembly 24 is properly wound and stored under the action of its internal return spring to avoid dragging inside the box 1.

[0065] When the guide rail 21 in the material guide mechanism 2 is adjusted in position, it synchronously drives the synchronous movement of each auxiliary component 35 in the spraying mechanism 3. When the auxiliary component 35 is displaced with the adjustment of the guide rail 21, its wedge plate 352 pushes the contact rod of the shielding component 344 in the corresponding coating component 34 during the adjustment process. When the contact rods on each integration plate 3442 in the shielding component 344 move with the displacement of the wedge plate 352, the multiple shielding sleeves 3443 connected thereto are synchronously driven to be displaced and adjusted on the corresponding spray pipe 343, and the corresponding reset spring is deformed. The displacement adjustment of the shielding sleeve 3443 on the spray pipe 343 realizes the shielding and blocking of the spray holes on both sides of the corresponding spray pipe 343, so that the spray holes left on the spray pipe 343 are suitable for the current substrate range.

[0066] After the adjustment of the material guiding mechanism 2 is completed, the inspection plate 15 is opened, and then the guiding part of the substrate to be processed is arranged from the retracting roller at the left position to the retracting roller at the right position. When arranging, the substrate must pass through the spraying treatment unit, the atmosphere reduction heat treatment unit and the traction drive unit, and must pass through the material guiding mechanism 2.

[0067] When the guide part of the substrate is arranged, the dust removal mechanism 5 and the drying mechanism 6 are turned on by the external controller. The substrate moves from left to right under the action of the traction drive unit, and the spray treatment unit first sprays and dries the graphene material on the substrate, and then the treated substrate is treated again in the atmosphere reduction heat treatment unit, and enters the reel roller at the right position for rewinding under the action of the traction drive unit.

[0068] The dust collecting device body 54 in the dust removal mechanism 5 is running, and then the side of the substrate to be sprayed into the box body 1 is dusted. The suction force generated by the dust collecting device body 54 causes each dust collecting air hole of the dust removal box 52 to generate suction under the action of the air inlet pipe, so as to realize the dust collection of the substrate above it. The impurities mixed in the absorbed gas are filtered in the filter plate 53, and then the gas is discharged from the exhaust pipe. The gas entering the exhaust pipe is heated by the heating wire 55, and finally, the heated air flow enters the leftmost tube body 41 in the auxiliary mechanism 4 under the transportation of the exhaust pipe. The heated gas entering the tube body 41 enters each tube body 41 under the action of each drainage pipe 43. When the heated gas passes through the tube body 41, its heat will make the corresponding heat-conducting tube 42 hot, and then the contacted substrate is preheated by the heated heat-conducting tube 42.

[0069] Finally, the heated gas enters the gas pipeline from the rear end of the rightmost tube body 41, and is then divided into three parts under the action of the gas pipeline. One part is discharged from the end of the main pipe to the interior of the box body 1, one part is discharged from the end of the branch pipe to the interior of the box body 1, and the other part enters the lower box body 611 of the hot air structure 61 in the drying mechanism 6 under the transportation of the auxiliary pipe.

[0070] The gas entering the lower box body 611 is discharged from the rectangular slot of the upper box body 612 to the interior of the box body 1. After the multiple heating rod bodies 613 provided in the lower box body 611 are turned on, the gas entering the lower box body 611 is further heated, so that the gas discharged into the box body 1 has a higher temperature, thereby drying the graphene material that has been sprayed.

[0071] During the movement of the base, the heat-conducting cylinder 42 on the far right moves efficiently, so that the corresponding outer groove cylinder 621 connected thereto rotates. Since the thread on the outer groove cylinder 621 is a reciprocating thread, the inner groove ring threaded thereon can move linearly under the action of the supporting rod loaded in the corresponding air guide assembly at the other end of the connecting rod 622 when the outer groove cylinder 621 rotates. Then the corresponding connecting rod 622 is driven to move synchronously, so that the supporting rod in the corresponding air guide assembly drives the corresponding moving plate 615 to adjust the telescopic movement, thereby realizing the swing of each air guide plate 614 thereon. The swing of the air guide plate 614 guides the gas discharged from the rectangular through slot to the inside of the box body 1, thereby ensuring the uniform drying of the graphene material that has been sprayed.

[0072] After the graphene material in the coating feeding unit is synthesized, the control valve on the feeding pipe is opened. The liquid pump body 7 is operated, and then the graphene material synthesized in the coating feeding unit is extracted through the feeding pipe. When the dust-removed substrate is moved to the spraying working area, according to the spraying component 34 in the spraying working area of ​​the spraying mechanism 3 at this time, the control valve set at the corresponding material end of the U-shaped tube is opened. Then the graphene material extracted by the liquid pump body 7 is pumped from the opened discharge end of the U-shaped tube. After leaving the U-shaped tube, the graphene material enters the feed pipe on the current spraying component 34, and then enters the hollow plate 342 of the spraying component 34.

[0073] The graphene material entering the hollow plate 342 is diverted to the corresponding spray pipes 343 in the spray assembly 34 under the pumping action of the liquid pump body 7, and then sprayed upward through the spray holes on the spray pipes 343, thereby achieving the graphene material spraying treatment on the substrate in the area.

[0074] At this time, the feed pipe on the spray assembly located in the non-working area overlaps with the corresponding port in the gas pipeline, and then part of the gas in the gas pipeline enters the hollow plate 342 in the spray assembly 34 and is diverted to the corresponding spray pipe 343. Since the spray holes on each spray pipe 343 in the spray assembly 34 are facing downward at this time, the airflow can spray the residue in the spray assembly 34 into the collection box 16 below for collection when it is sprayed out from each spray hole, thereby realizing the self-cleaning treatment of the spray assembly 34.

[0075] When the graphene material in the coating feeding unit is exhausted and needs to be synthesized again or the matrix needs to be rearranged, it is necessary to switch and adjust each spraying assembly 34 in the spraying mechanism 3. When the spraying mechanism 3 is switched, the motor 31 is operated, so that the transmission shaft on the left side is active, and then the two toothed chain members 32 move synchronously. When the toothed chain member 32 is in operation, the various spraying assemblies 34 arranged thereon are transposed. When each spraying assembly 34 is transposed, the spraying assembly 34 in the spraying working area moves to the left, and the spraying assembly 34 in the non-working area moves to the right. When the spraying assembly 34 moves to the left, the ejector rod 3454 of the reversing member 345 on it leaves the partition 12, and under the action of the spring telescopic rod 3455, the top plate 3453 drives each rack 3452 to reset. When the rack 3452 is reset, the gear 3451 meshed with it causes the corresponding spray pipe 343 to rotate and switch. When the spring telescopic rod 3455 is reset to the initial state, the push rod 3454 is separated from the partition 12, and the spray pipe 343 completes a half-circle rotation switch. At this time, the spray hole on the spray pipe 343 faces downward. During the leftward movement of the spray assembly 34, the contact rod on the shielding member 344 is separated from the wedge plate 352 of the corresponding auxiliary member 35, and then the shielding member 344 is driven by each integration plate 3442 on the shielding member 344 to reset to the initial state under the action of the reset spring. When the spray assembly 34 is moved to the non-working area, each contact rod in the shielding member 344 contacts the wedge plate 352 in the corresponding auxiliary member 35 again, so that each integration plate 3442 drives the corresponding shielding sleeve 3443 to move and adjust to the same position in the spraying working area.

[0076] When the spray assembly 34 moves to the right, the adjustment method of the shielding member 344 on the spray assembly 34 is the same as described above, and after the ejector rod 3454 thereof hits the partition 12, as the spray assembly 34 continues to move, the reversing member 345 realizes a half-circle adjustment of each spray pipe 343 thereon, so that the spray hole on the spray pipe 343 faces upward.

[0077] After the spray assembly 34 moves to the left, the feed pipe on the spray assembly 34 corresponds to the end of the corresponding air supply pipe, and after the spray assembly 34 moves to the right, the feed pipe on the spray assembly 34 corresponds to the corresponding U-shaped tube, thereby completing the switching adjustment of the spray mechanism 3. When the subsequent equipment is running, the self-cleaned spray assembly 34 can be used to spray the graphene material on the substrate, and the spray assembly 34 after use is moved to the non-working area for self-cleaning treatment with the help of airflow.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
