Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and specifically to a production equipment for graphene coatings. Background Art

[0002] A 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, and is widely used in fields such as medical, industrial, electronic, military, metallurgical, vehicle, textile fabric, chemical, electric power, and building. Among them, in lithium-ion batteries, carbon-coated aluminum foil is used as a current collector, and two surfaces of the current collector are respectively coated with a layer of conductive carbon coating, which improves the adhesion between the electrode material and the current collector, the electrical conductivity of the overall electrode sheet, and the properties such as resistance to electrolyte corrosion and high voltage of the conductive current collector.

[0003] When producing a graphene coating on a current collector, its production equipment consists of multiple processing devices. For example, a Chinese patent with an application number of 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 whose one end is communicated with the bottom of the slurry barrel and the other end is communicated with an electrostatic spraying needle, and the electrostatic spraying needle is arranged inside a housing.

[0004] Although the technical solution in the above patent document realizes surface spraying treatment on the substrate serving as the current collector, it still has the following defects: In the device for spraying and processing graphene materials, its spraying structure mostly adopts a fixed setting. Thus, if the graphene material needs to be regenerated or the substrate needs to be rearranged after its use, it is inevitable to suspend the spraying of the graphene material. And both the regeneration of the graphene material and the rearrangement of the substrate require a lot of time. The graphene material remaining inside the used spraying structure is extremely likely to cause blockage of the spraying structure. Therefore, when using it again, it is necessary to clean or replace the spraying structure, which is not only troublesome, increasing the burden on the staff, but also further increasing the use cost of the product and reducing its production efficiency; Before the substrate is subjected to graphene coating treatment, it will be pre-cleaned. However, after being cleaned and transported and assembled onto the equipment, the substrate will inevitably come into contact with dust and other impurities in the air. Thus, when directly coating it, the adsorption effect between the graphene material and the substrate is likely to be affected due to the existence of dust and other impurities. Summary of the Invention

By switching and adjusting the two spraying components, the used spraying components are replaced and self-cleaned by the airflow generated by the dust removal mechanism.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] By setting up a dust removal mechanism, adsorption dust removal is carried out on the substrate before spraying, ensuring the cleanliness of the substrate surface, so that there is a good adsorption effect between the substrate and the graphene material, thereby ensuring the qualification rate of graphene coating production.

[0031] By setting up a spraying mechanism to replace the fixed spraying structure, there are two displaceable and adjustable spraying components in the spraying mechanism. By driving the operation of the gear chain part by a motor, the switching adjustment of the two spraying components is realized. In this way, the used spraying components can be transposed and self-cleaned by means of the airflow generated by the dust removal mechanism, avoiding the trouble of frequent manual cleaning, reducing the burden on the staff, reducing the equipment cost, and improving the production efficiency of the product.

[0032] When the spraying component is transposed and adjusted under the operation of the conveying component, the spraying component in the non-working area will adjust the orientation of the spray holes under the action of the reversing part, and then when the air flows through, the residues remaining inside it will enter the collection box, thereby reducing the waste of resources and preventing the residues from splashing randomly inside the box during self-cleaning.

[0033] The airflow generated by the dust removal mechanism can be heated under the action of the heating wire, and the heated airflow enters the auxiliary mechanism to preheat the passing substrate. Part of the airflow discharged from the auxiliary mechanism self-cleans the transposed spraying component, and the other part enters the drying mechanism, and under the further heating action of the drying mechanism, the drying process of the graphene material that has been sprayed on the substrate can be accelerated.

[0034] There are two groups of air guiding components in the drying mechanism, which cooperate with the adjusting component to flexibly adjust the direction of the two groups of air guiding components by using the power generated when the substrate passes through the auxiliary mechanism, so as to ensure the uniformity of the drying treatment of the graphene material sprayed on the substrate by the drying mechanism.

[0035] By setting up a feeding mechanism, substrates with similar widths can be used adaptively, thereby improving the applicability effect of the product. Moreover, when the feeding 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 the current substrate, further improving the applicability of the product.

[0036] When the material guiding mechanism is adjusted, it can synchronously drive multiple baffle components to stretch and block the fabric, so as to block the excess parts of the access openings on both sides of the box body, thereby reducing the impact of the smell generated by the graphene material on the staff and ensuring the safety of the working environment.

After the contact rod on the shielding member 344 in each spraying assembly 34 contacts the inclined surface of the corresponding wedge plate 352 on the auxiliary part 35, the position of the shielding member 344 is adjusted, so that the number of spray holes on each spray pipe 343 in the spraying assembly 34 is adapted to the specifications of the substrate to be processed.

When the substrate passes through the rightmost heat conduction cylinder 42, the substrate bypasses the heat conduction cylinder 42 upward, and then smoothly enters onto the two guide rails 21 under the action of the pressure roller 14. The substrate passes through the rightmost heat conduction cylinder 42 to ensure that the heat conduction cylinder 42 at this place can provide sufficient power for the wind direction adjustment of the drying mechanism 6.

[0086] Please refer to Figures 4 - 5 and Figures 13 - 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. 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 slots are symmetrically opened on the top shell wall of the upper box body 612 from left to right, and a wind guiding component is arranged in each rectangular through slot. The arrangement of the wind guiding component can discharge the wind entering the lower box body 611 in an adjusted wind direction.

[0087] The wind guiding component includes a plurality of wind guiding plates 614 linearly distributed in the rectangular through slots. A through notch is opened inside each wind guiding plate 614, and a carrying shaft is arranged in the through notch. The two ends of the carrying shaft are respectively fixedly connected to the corresponding inner walls of the rectangular through slots, and a groove is opened on the bottom shell wall of each wind guiding plate 614, and a round rod is arranged in the groove.

[0088] A moving plate 615 is commonly connected between the plurality of round rods. Support rods are installed at both ends of the moving plate 615, and the end of the support rod far from the moving plate 615 penetrates through the corresponding side wall of the upper box body 612. The support rods arranged at both ends of the moving plate 615 can ensure the stability of the movement adjustment of the moving plate 615 after penetrating through the corresponding side wall of the upper box body 612. The adjustment of the moving plate 615 can realize the angle adjustment of the plurality of wind guiding plates 614 connected thereto.

[0089] The adjustment component 62 is composed of an external thread cylinder 621 and a connecting rod 622.

The two ends of the two connecting rods 622 far from the corresponding internal thread rings are respectively loaded on the corresponding support rods of the two wind guiding components, so as to realize the reverse adjustment of the two wind guiding components. The reverse adjustment of the corresponding wind guiding plates 614 in the two wind guiding components further expands the uniformity of the drying of the substrate.

[0090] Please refer to Figure 2 And Figure 5, in the embodiments of the present invention, the gas transmission 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 at the rear end of the rightmost pipe body 41 through a connector. The bottom end of the main pipe penetrates the rear shell wall of the housing 11, and both the branch pipe and the secondary pipe are connected to the main pipe. Among them, the other end of the branch pipe also penetrates the rear shell wall of the housing 11, and the end of the branch pipe is 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 spraying components 34 at the upper and lower positions in the spraying mechanism 3 when they are in the non-working area, so as to realize the self-cleaning treatment of the spraying components 34 by the air flow.

[0091] The working principle of the present invention is as follows: When performing graphene coating treatment on the substrate, first fine-tune the feeding mechanism 2 according to the specifications of the substrate to be treated. During the fine-tuning process of the feeding mechanism 2, the graphene material to be sprayed is synthesized by the coating feeding unit. When the feeding mechanism 2 is adjusted, the electric push rods 22 at both sides are started through an external controller device, and their output ends perform synchronous telescopic movements. Then, under the action of the corresponding movable rods 23, the distance between the front and rear symmetrically arranged guide rails 21 is adjusted to a distance that can adapt to the corresponding substrate. When the guide rail 21 is adjusted in displacement, it stretches the blocking fabric 242 in the corresponding blocking assembly 24, so that it can properly block the passage opening on the side wall of the housing 11. If the two guide rails 21 are adjusted to move away from each other at this time, the blocking fabric 242 in the corresponding blocking assembly 24 is appropriately wound and stored under the action of the return spring inside it, avoiding dragging inside the box body 1.

[0092] When the guide rail 21 in the feeding mechanism 2 is adjusted in position, it synchronously drives the synchronous movement of each auxiliary part 35 in the spraying mechanism 3. When the auxiliary part 35 is displaced with the adjustment of the guide rail 21, the wedge-shaped plate 352 pushes the contact rod of the shielding part 344 in the corresponding spraying component 34 during the adjustment process. When the contact rods on each integrated plate 3442 of the shielding part 344 move with the displacement of the wedge-shaped plate 352, they synchronously drive a plurality of shielding sleeves 3443 connected thereto to perform displacement adjustment on the corresponding spraying pipe 343, causing the corresponding return spring to deform. The displacement adjustment of the shielding sleeve 3443 on the spraying pipe 343 realizes the blocking and sealing of the spray holes at both sides of the corresponding spraying pipe 343, so that the spray holes left on the spraying pipe 343 are suitable for the current substrate range.

[0093] After the feeding mechanism 2 is adjusted, open the inspection plate 15, and then arrange the guiding part of the substrate to be treated from the winding and unwinding roller at the left side to the winding and unwinding roller at the right side. When the substrate is arranged, it needs to pass through the spraying treatment unit, the atmosphere reduction heat treatment unit and the traction drive unit, and it needs to pass through the feeding mechanism 2.

[0094] After the guiding part of the substrate is arranged, the dust removal mechanism 5 and the drying mechanism 6 are started through an external controller device. Under the action of the traction drive unit, the substrate moves from left to right. The spraying and drying treatment of graphene material on the substrate is carried out by the spraying treatment unit first. Then the treated substrate is further processed in the atmosphere reduction heat treatment unit and enters the take-up and pay-off reel at the right position for winding under the action of the traction drive unit.

[0095] The dust suction device main body 54 in the dust removal mechanism 5 operates, and then the surface of the substrate to be sprayed and treated entering the box body 1 is subjected to dust suction treatment. The suction force generated by the dust suction device main body 54 causes suction force at each dust suction hole of the dust removal box 52 under the action of the air inlet pipe, so as to realize the dust suction treatment of the substrate above it. The impurities doped in the absorbed gas are filtered in the filter screen plate 53, and then the gas is discharged from the exhaust pipe. The gas entering the exhaust pipe is heated under the heating action of the heating wire 55. Finally, the heated air flow enters the leftmost pipe body 41 of the auxiliary mechanism 4 under the transportation of the exhaust pipe. The heated gas entering the pipe body 41 enters each pipe body 41 under the action of each diversion pipe 43. When the heated gas passes through the pipe body 41, its heat will make the corresponding heat conduction cylinder 42 become hot, and then the substrate contacted by the heated heat conduction cylinder 42 is preheated.

[0096] Finally, the heated gas enters the gas transmission pipeline from the rear end of the rightmost pipe body 41, and then is divided into three parts under the action of the gas transmission pipeline. One part is discharged to the inside of the box body 1 from the end of the main pipe, one part is discharged to the inside of the box body 1 from the end of the branch pipe, 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.

[0097] The gas entering the lower box body 611 is discharged to the inside of the box body 1 from the rectangular through groove of the upper box body 612. After the multiple heating rod bodies 613 arranged in the lower box body 611 are started, 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, so as to dry the sprayed graphene material.

[0098] During the movement of the substrate, the rightmost heat-conducting cylinder 42 moves efficiently, causing the corresponding outer-threaded cylinder 621 connected thereto to rotate. Since the threads on the outer-threaded cylinder 621 are reciprocating threads, when the outer-threaded cylinder 621 rotates, the inner-threaded ring connected to its threads can perform a linear motion under the action of the support rod at the other end of the connecting rod 622 loaded in the corresponding air-guiding component. Then, it drives the corresponding connecting rod 622 to move synchronously, causing the support rod in the corresponding air-guiding component to drive the corresponding moving plate 615 to perform telescopic adjustment, and further realizing the swing of each air-guiding plate 614 thereon. The swing of the air-guiding plate 614 guides the gas discharged from the rectangular through-hole into the interior of the box body 1, thereby ensuring uniform drying treatment of the graphene material after spraying.

[0099] After the synthesis of the graphene material in the coating feeding unit is completed, the control valve on the feed pipe is opened. The liquid extraction pump main body 7 operates, and then extracts the synthesized graphene material in the coating feeding unit through the feed pipe. When the substrate after dust removal moves to the spraying working area, according to the spraying component 34 in the spraying mechanism 3 in the spraying working area at this time, the control valve provided at the corresponding material end of the U-shaped pipe is opened. Then, the graphene material extracted by the liquid extraction pump main body 7 is pumped from the opened discharge end of the U-shaped pipe. After leaving the U-shaped pipe, the graphene material enters the feed pipe on the current spraying component 34 and thus enters the hollow plate 342 of the spraying component 34.

[0100] The graphene material entering the hollow plate 342 is shunted into the corresponding spraying pipes 343 in the spraying component 34 under the pumping action of the liquid extraction pump main body 7, and then is sprayed upward through the spray holes on the spraying pipes 343, thereby realizing the spraying treatment of the graphene material on the substrate in this area.

[0101] At this time, for the spraying component located in the non-working area, the feed pipe thereon coincides with the corresponding port in the gas transmission pipeline. Then, part of the gas in the gas transmission pipeline enters the hollow plate 342 in the spraying component 34 and is shunted into the corresponding spraying pipes 343. Since the spray holes on each spraying pipe 343 in the spraying component 34 face downward at this time, when the air flow sprays out from each spray hole, the residues in the spraying component 34 can be sprayed into the collection box 16 below for collection, thereby realizing the self-cleaning treatment of the spraying component 34.

[0102] When the graphene material in the coating feeding unit is exhausted and needs to be synthesized again or the substrate needs to be rearranged, it is necessary to switch and adjust each spraying component 34 in the spraying mechanism 3. When the spraying mechanism 3 is running in a switched mode, the motor 31 operates, causing the left transmission shaft to move, and then causing the two toothed chain parts 32 to move synchronously. When the toothed chain parts 32 are running, they displace each spraying component 34 arranged thereon. When each spraying component 34 is displaced, the spraying component 34 in the spraying working area moves to the left, while the spraying component 34 in the non-working area moves to the right. When the spraying component 34 moves to the left, the push rod 3454 of the reversing part 345 thereon leaves the partition plate 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 resets, the corresponding spraying pipe 343 is rotated and switched by the required gear 3451 meshing with it. When the spring telescopic rod 3455 resets to the initial state, the push rod 3454 disengages from the partition plate 12, and the spraying pipe 343 completes a half-turn rotation and switching. At this time, the spray holes on the spraying pipe 343 face downward. During the process of the spraying component 34 moving to the left, since the contact rod on the shielding part 344 disengages from the wedge-shaped plate 352 of the corresponding auxiliary part 35, the shielding part 344 drives each integrated plate 3442 thereon to drive the corresponding shielding sleeve 3443 to reset to the initial state under the action of the reset spring. When the spraying component 34 moves to the non-working area, the contact rods in the shielding part 344 thereof come into contact with the wedge-shaped plates 352 in the corresponding auxiliary parts 35 again, so that each integrated plate 3442 drives the corresponding shielding sleeve 3443 to move and adjust to reach the same position as when it is in the spraying working area.

[0103] When the spraying component 34 moves to the right, the adjustment method of the shielding part 344 on the spraying component 34 is the same as that described above. After the push rod 3454 of the reversing part 345 thereon abuts against the partition plate 12, as the spraying component 34 continues to move, the reversing part 345 realizes a half-turn adjustment of each spraying pipe 343 thereon, so that the spray holes on the spraying pipe 343 face upward.

[0104] After the spraying component 34 moves to the left, the feeding pipe on the spraying component 34 corresponds to the end of the corresponding gas transmission pipe, and after the spraying component 34 moves to the right, the feeding pipe on the spraying component 34 corresponds to the corresponding U-shaped pipe, thus completing the switching and adjustment of the spraying mechanism 3. During the subsequent operation of the equipment, the spraying component 34 that has undergone self-cleaning can be used to spray the graphene material on the substrate, and the used spraying component 34 is displaced to the non-working area for self-cleaning treatment by means of air flow.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
