Description

Technical Field

[0001] The present invention relates to the technical field of ink coating, and particularly to a photosensitive ink coating device for an automotive horn mesh sheet and a coating process thereof. Background Art

[0002] In the etching process of an automotive horn mesh sheet, it is necessary to accurately transfer the designed mesh pattern, etc. onto a metal substrate. After coating the photosensitive ink, through the exposure process, the photosensitive ink will undergo a photochemical reaction according to the pattern of the mask plate. The ink in the exposed part will solidify, and the unexposed part can be removed during the development process, thereby forming an anti-corrosion layer on the surface of the mesh sheet that is consistent with the designed pattern, providing an accurate etching area for the subsequent etching process, and ensuring the accuracy and precision of patterns such as mesh holes. The roll coating device rotates a coating roll in an ink tank to make the surface of the roll adhere to the ink, and then contacts the automotive horn mesh sheet to transfer the ink onto the mesh sheet. The coating amount and uniformity of the ink are controlled by adjusting parameters such as the pressure and speed between the coating roll and the mesh sheet.

[0003] When coating the photosensitive ink, the roll coating method is usually adopted for ink coating. However, during roll coating, due to the small contact pressure between the plate and the ink roll, the ink cannot be smoothly transferred from the ink roll to the surface of the plate, affecting the coating effect of the plate. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A photosensitive ink coating device for an automotive horn mesh sheet, comprising:

[0006] A frame body, on the top of which a conveying mechanism is fixedly installed, and a fixing plate is installed inside the conveying mechanism;

[0007] A roll coating mechanism, which is used to store the photosensitive ink and coat the surface of the sheet when the mesh sheet passes by;

[0008] A drying mechanism, which is installed on the top of the frame body, and the roll coating mechanism is installed on one side of the top of the frame body away from the drying mechanism;

[0009] The top of the fixed plate is symmetrically provided with column holes, and sliding columns are installed at the column holes of the fixed plate. The top ends of the sliding columns are fixedly installed with a blanking plate. Both sides of the blanking plate are inclined downward slopes. The bottom ends of the sliding columns are fixedly installed with limiting discs. A rubber cushion plate is fixedly installed between the blanking plate and the fixed plate. Through the elastic deformation of the rubber cushion plate, when the plate passes through, by the oppression of the plate on the blanking plate under the restriction of the roll coating mechanism, the rubber cushion plate deforms, and the blanking plate moves downward, ensuring that the plate groove smoothly passes through the bottom of the roll coating mechanism to complete the coating work. At the same time, the deformed rubber cushion plate generates an elastic force to ensure the contact pressure between the plate and the coating roller when the plate passes through, avoiding the situation that when the plate is coated, due to insufficient contact pressure between the plate and the coating roller, the ink cannot adhere to the top of the plate. One side of the bottom of the fixed plate far from the drying mechanism is fixedly installed with a fixed strip, and a guide roller is rotatably installed on the inner wall of the fixed strip. By the cooperation of the guide roller and the inclined surfaces on both sides of the blanking plate, it ensures the pressure to lift the plate when the plate passes through, and at the same time ensures that the plate smoothly reaches the top of the blanking plate under the drive of the conveying mechanism, avoiding the phenomenon of plate jamming and preventing the plate from being coated with ink.

[0010] The conveying mechanism includes side plates, which are symmetrically installed on both sides of the top of the frame along the axis center position of the frame. A transmission shaft is rotatably installed between the side plates, and the transmission shaft is symmetrically installed along the axis center position of the side plates. The opposite surfaces of the side plates are fixedly connected to both ends of the fixed plate. A first motor is fixedly installed on the outside of the side plates, and the output end of the first motor is fixedly connected to one end of the transmission shaft. A conveyor belt is installed between the transmission shafts in a transmission manner. The blanking plate is located inside the conveyor belt, and the top of the blanking plate is in contact with the inner wall of the conveyor belt.

[0011] Preferably, the roll coating mechanism includes a fixed frame, which is fixedly installed on the top of the frame, and an ink storage tank is fixedly installed on the top of the fixed frame. A second motor is fixedly installed on the outside of the ink storage tank, and a rotating shaft is rotatably installed on the inner wall of the ink storage tank. One end of the rotating shaft is fixedly connected to the output end of the second motor. A roller is fixedly installed on the outside of the rotating shaft, and a scraping plate is fixedly installed on the outside of the roller. The scraping plates are evenly installed along the center position of the roller, and the widths of both ends of the scraping plate gradually increase from the outside to the inside. By changing the width of the scraping plate, the widths of both ends of the scraping plate are smaller than the width of the center position, ensuring the driving effect on the ink at the center position. At the same time, when scraping, after ink lumps appear in the ink, gaps are formed between the smaller widths on both sides of the scraping plate and the ink storage tank, so that the ink lumps can leak out through the gaps, avoiding the situation that the ink lumps cannot leak out and causing jamming between the scraping plate and the ink storage tank.

[0012] Preferably, a coating roller is rotatably installed at the bottom of the ink storage tank. The outer side of the coating roller is closely attached to the inner wall of the ink storage tank, and ink grooves are evenly formed on the outer side of the coating roller. On both sides of the bottom of the inner wall of the ink storage tank, side folding plates are fixedly installed. Empty grooves are formed at the tops of the side folding plates, and notch grooves are formed at the bottoms of the opposite surfaces of the side folding plates. Through the cooperation of the empty grooves and notch grooves of the side folding plates, after the caked ink and uncaked ink enter through the empty grooves at the same time, the notch grooves on the opposite surfaces cooperate with the arc-shaped filter plates, so that the uncaked ink can filter out the caked ink and smoothly concentrate at the center position of the bottom of the ink storage tank, ensuring sufficient ink volume at the roll coating position, avoiding uneven coating of the plate. And arc-shaped filter plates are fixedly installed at the tops of the opposite surfaces of the side folding plates. The top of the arc-shaped filter plate does not contact the scraping plate. Through the non-contact between the arc-shaped filter plate and the scraping plate, the driving of the ink by the scraping plate during rotation is ensured, and at the same time, the caked ink at the top of the arc-shaped filter plate is prevented from being squeezed through the arc-shaped filter plate under the rotation of the scraping plate, resulting in caked ink at the ink application position of the coating roller and affecting the coating effect of the ink, making the ink on the coating surface uneven.

[0013] Preferably, the drying mechanism includes a drying hood. Hot air blowers are fixedly installed at the tops of the drying hoods. A conduction pipe is fixedly installed at the bottom of the hot air blower. Connecting plates are fixedly installed on both sides of the inner wall of the drying hood. Air outlet pipes are fixedly installed on the opposite surfaces of the connecting plates. The tops of the air outlet pipes are communicated with the conduction pipe. A hot air hood is fixedly installed between the air outlet pipes. A rectangular groove is formed at the center position of the bottom of the hot air hood, and a strip groove plate is fixedly installed at the rectangular groove of the hot air hood. Strip grooves are evenly formed at the top of the strip groove plate. A bottom strip is fixedly installed at the center position of the bottom of the strip groove plate. An inclined groove plate is fixedly installed at the bottom of the bottom strip, and inclined through grooves are symmetrically formed at the bottom of the inclined groove plate along the center position.

[0014] A photosensitive ink coating process for automotive horn mesh sheets consists of the following steps:

[0015] S1. Plate cleaning: The surface of the plate is cleaned with a professional cleaning solution to remove the oil stains on the ink coating surface of the plate, ensuring that the coating surface of the plate is clean before coating.

[0016] S2. Plate drying: The residual water droplets on the cleaned surface of the plate are dried through a hot air drying device to keep the surface of the plate dry.

[0017] S3. Ink roll coating: The photosensitive ink is evenly roll-coated on the ink coating surface of the plate through equipment, so that the photosensitive ink is evenly attached to the surface of the plate.

[0018] S4. Ink drying: The surface of the plate coated with ink is blown with hot air, so that the ink coated on the surface of the plate dries quickly and solidifies on the surface of the plate.

[0019] The present invention provides a photosensitive ink coating device for automotive horn mesh sheets, with the following beneficial effects:

[0020] First, in the photosensitive ink coating device for automotive horn mesh sheets, through the elastic deformation of the rubber cushion plate, when the sheet passes through, by the pressure of the sheet on the top material plate restricted by the roll coating mechanism, the rubber cushion plate deforms, and the top material plate moves downward, ensuring that the sheet groove smoothly passes through the bottom of the roll coating mechanism to complete the coating work. At the same time, the deformed rubber cushion plate generates elastic force to ensure the contact pressure between the sheet and the coating roller when the sheet passes through, avoiding the situation where the ink cannot adhere to the top of the sheet due to insufficient contact pressure between the sheet and the coating roller during coating.

[0021] Second, in the photosensitive ink coating device for automotive horn mesh sheets, through the cooperation of the guide roller and the inclined surfaces on both sides of the top material plate, it ensures the pressure to lift the sheet when the sheet passes through, and at the same time ensures that the sheet smoothly reaches the top of the top material plate driven by the conveying mechanism, avoiding the phenomenon of sheet jamming and preventing the sheet from being coated with ink.

[0022] Third, in the photosensitive ink coating device for automotive horn mesh sheets, by changing the width of the ink scraping plate, the widths at both ends of the ink scraping plate are smaller than the width at the central position, ensuring the driving effect on the ink at the central position. At the same time, when scraping, after lumps appear in the ink, gaps are formed between the smaller widths on both sides of the ink scraping plate and the ink storage tank, allowing the ink lumps to leak out through the gaps, avoiding the situation where the ink lumps cannot leak out and causing jamming between the ink scraping plate and the ink storage tank.

[0023] Fourth, in the photosensitive ink coating device for automotive horn mesh sheets, through the cooperation of the empty slots and missing slots of the side folding plates, after the lumpy ink and un-lumpy ink enter through the empty slots at the same time, the missing slots on the opposite sides cooperate with the arc-shaped filter plate, enabling the un-lumpy ink to filter out the lumpy ink and smoothly concentrate at the central position at the bottom of the ink storage tank, ensuring sufficient ink volume at the roll coating position and avoiding uneven coating of the sheet.

[0024] Fifth, in the photosensitive ink coating device for automotive horn mesh sheets, by keeping the arc-shaped filter plate and the ink scraping plate non-contact, it ensures the driving of the ink when the ink scraping plate rotates, and at the same time avoids the lumpy ink on the top of the arc-shaped filter plate being squeezed through the arc-shaped filter plate during the rotation of the ink scraping plate, resulting in lumpy ink at the ink application position on the coating roller and affecting the coating effect of the ink, making the ink on the coating surface uneven.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] The first embodiment is as follows Figures 1 to 6 shown, the present invention provides a technical solution:

[0040] A photosensitive ink coating device for an automobile horn mesh sheet, comprising:

[0041] A frame body 1, on the top of which a conveying mechanism 3 is fixedly installed, and a fixing plate 6 is installed inside the conveying mechanism 3;

[0042] A roll coating mechanism 2, which is used to store photosensitive ink and coat the surface of the sheet with ink when the mesh sheet passes by;

[0043] A drying mechanism 4 is installed on the top of the frame body 1, and the roll coating mechanism 2 is installed on one side of the top of the frame body 1 away from the drying mechanism 4;

[0044] Column holes are symmetrically formed at the top of the fixing plate 6, and sliding columns 10 are slidably installed at the column holes of the fixing plate 6. The top ends of the sliding columns 10 are fixedly installed with a top plate 7. Both sides of the top plate 7 are inclined downward slopes. The bottom ends of the sliding columns 10 are fixedly installed with limit discs 11. The sheet is driven by the conveying mechanism 3 to move. During the movement, the sheet first cooperates with the top plate 7 through the guide roller 5. By using the slopes on both sides of the top plate 7 and the rotation of the guide roller 5, the sheet smoothly reaches the top of the top plate 7 driven by the conveying mechanism 3. A rubber cushion plate 9 is fixedly installed between the top plate 7 and the fixing plate 6. A fixing strip 8 is fixedly installed on one side of the bottom of the fixing plate 6 away from the drying mechanism 4. During the process of the sheet moving to the top of the top plate 7, through the restriction of the roll coating mechanism 2, the sheet presses down the top plate 7, causing the top plate 7 to compress the rubber cushion plate 9 to deform, causing the top plate 7 to move downward to provide space for the sheet to pass smoothly. At the same time, the elastic force generated after the deformation of the rubber cushion plate 9 generates an upward thrust on the passing sheet through the top plate 7, causing a fitting pressure between the sheet and the roll coating mechanism 2. A guide roller 5 is rotatably installed on the inner wall of the fixing strip 8.

[0045] The conveying mechanism 3 includes side plates 31. The side plates 31 are symmetrically installed on both sides of the top of the frame body 1 along the central axis position of the frame body 1. A transmission shaft 34 is rotatably installed between the side plates 31. The transmission shaft 34 is symmetrically installed along the central axis position of the side plates 31. The opposite surfaces of the side plates 31 are fixedly connected to both ends of the fixing plate 6. A first motor 32 is fixedly installed on the outer side of the side plates 31. The first motor 32 drives the transmission shaft 34 to rotate, so that the transmission shaft 34 drives the conveyor belt 33 to move, and the conveyor belt 33 drives the plates placed on the top to move, so that the plates pass through the roller coating mechanism 2 and the drying mechanism 4 in sequence, realizing the coating of photosensitive ink on the surface of the plates and the drying of the photosensitive ink tube. The output end of the first motor 32 is fixedly connected to one end of the transmission shaft 34. A conveyor belt 33 is installed between the transmission shafts 34 in a transmission manner. The top plate 7 is located inside the conveyor belt 33, and the top of the top plate 7 is in contact with the inner wall of the conveyor belt 33.

[0046] The second embodiment, on the basis of the first embodiment, please refer to Figures 7 to 8 As shown, the roller coating mechanism 2 includes a fixing frame 21. The fixing frame 21 is fixedly installed on the top of the frame body 1, and an ink storage tank 23 is fixedly installed on the top of the fixing frame 21. A second motor 22 is fixedly installed on the outer side of the ink storage tank 23, and a rotating shaft 24 is rotatably installed on the inner wall of the ink storage tank 23. One end of the rotating shaft 24 is fixedly connected to the output end of the second motor 22. A roller 25 is fixedly installed on the outer side of the rotating shaft 24. Workers pour photosensitive ink into the ink storage tank 23. At the same time, during the process of roller coating the ink, the second motor 22 drives the rotating shaft 24 to rotate, so that the rotating shaft 24 drives the roller 25 inside the ink storage tank 23 to rotate. During the rotation of the roller 25, the scraping plate 26 is driven to rotate, so that the scraping plate 26 drives the photosensitive ink to move during the rotation, ensuring that there is sufficient photosensitive ink at the bottom of the ink storage tank 23. At the same time, after the photosensitive ink reaches the bottom, the agglomerates in the ink are filtered by the arc-shaped filter plate 27, so that the agglomerates are concentrated on both sides of the bottom under the drive of the scraping plate 26 of the photosensitive ink, and the agglomerated ink enters the inner side of the side folding plate 29 through the square groove at the top of the side folding plate 29. A scraping plate 26 is fixedly installed on the outer side of the roller 25. The scraping plates 26 are evenly installed along the center position of the roller 25, and the width of both ends of the scraping plate 26 gradually increases from the outside to the inside.

[0047] At the bottom of the ink storage tank 23, a coating roller 28 is rotatably installed. The outer side of the coating roller 28 is in close contact with the inner wall of the ink storage tank 23, and ink grooves are evenly formed on the outer side of the coating roller 28. On both sides of the bottom of the inner wall of the ink storage tank 23, side folding plates 29 are fixedly installed. Empty grooves are formed at the tops of the side folding plates 29, and notch grooves are formed at the bottoms of the opposite surfaces of the side folding plates 29. When the plate passes through the bottom of the coating roller 28, the coating roller 28 is driven to rotate during the movement by contact with the coating roller 28, and the photosensitive ink is coated on the surface of the plate during the rotation process to achieve ink coating. An arc-shaped filter plate 27 is fixedly installed at the top of the opposite surfaces of the side folding plates 29, and the top of the arc-shaped filter plate 27 is not in contact with the ink scraping plate 26.

[0048] The third embodiment is based on the first and second embodiments. Please refer to Figures 9 to 12 As shown, the drying mechanism 4 includes a drying hood 41. At the top of the drying hood 41, a hot air blower 42 is fixedly installed. At the bottom of the hot air blower 42, a conduction pipe 47 is fixedly installed. On both sides of the inner wall of the drying hood 41, connecting plates 46 are fixedly installed. Air outlet pipes 45 are fixedly installed on the opposite surfaces of the connecting plates 46. The tops of the air outlet pipes 45 are communicated with the conduction pipe 47. A hot air hood 43 is fixedly installed between the air outlet pipes 45. The hot air blower 42 heats the air, so that the hot air is transmitted to the air outlet pipes 45 through the conduction pipe 47, and the air outlet pipes 45 introduce the hot air into the hot air hood 43, increasing the air pressure inside the hot air hood 43. A rectangular groove is formed at the center of the bottom of the hot air hood 43, and a strip groove plate 44 is fixedly installed at the rectangular groove of the hot air hood 43. Strip grooves are evenly formed at the top of the strip groove plate 44. At the center of the bottom of the strip groove plate 44, a bottom strip 48 is fixedly installed. At the bottom of the bottom strip 48, an inclined groove plate 49 is fixedly installed. After the air pressure increases, the hot air is led out through the strip groove plate 44 installed at the bottom rectangular groove. After being led out, the inclined groove plate 49 fixedly connected to the bottom strip 48 blocks the movement of the hot air. At the same time, the hot air is guided to both sides through the inclined through grooves of the inclined groove plate 49, blowing the plate passing through the bottom of the inclined groove plate 49, drying the photosensitive ink coated on the top of the plate, and inclined through grooves are symmetrically formed along the center position at the bottom of the inclined groove plate 49.

[0049] A photosensitive ink coating process for an automotive horn mesh is composed of the following steps:

[0050] S1. Plate cleaning: The surface of the plate is cleaned with a professional cleaning solution to remove the oil stains on the ink coating surface of the plate, ensuring that the coating surface is clean before the plate is coated.

[0051] S2. Plate drying: The residual water droplets on the cleaned surface of the plate are dried through a hot air drying device to keep the surface of the plate dry.

[0052] S3. Ink roller coating: The photosensitive ink is evenly roller-coated on the ink-coated surface of the board by the equipment, so that the photosensitive ink adheres to the board surface evenly.

[0053] S4. Ink drying: By blowing hot air on the surface of the board after coating, the ink coated on the board surface dries quickly and solidifies on the board surface.

[0054] During use, the worker puts the cleaned board into the device from the side close to the roller coating mechanism 2, places the coating surface of the board upward into the conveying mechanism 3, drives the board to move towards the bottom of the roller coating mechanism 2 through the conveying mechanism 3. After reaching the bottom of the roller coating mechanism 2, the roller coating mechanism 2 coats the photosensitive ink on the top of the board. Subsequently, the conveying mechanism 3 continues to drive the board to move into the drying mechanism 4, dries the photosensitive ink through the drying mechanism 4, and then the conveying mechanism 3 exports the dried board.

[0055] When the board moves towards the bottom of the roller coating mechanism 2, the conveying mechanism 3 drives the board to move. During the movement, the board first cooperates with the guide roller 5 and the top plate 7. By using the cooperation between the inclined surfaces on both sides of the top plate 7 and the rotation of the guide roller 5, the board smoothly reaches the top of the top plate 7 driven by the conveying mechanism 3. During the process of the board moving to the top of the top plate 7, due to the restriction of the roller coating mechanism 2, the board presses down the top plate 7, causing the rubber cushion 9 under the top plate 7 to deform, and the top plate 7 moves downward, providing space for the board to pass smoothly. At the same time, after the rubber cushion 9 deforms, it generates an elastic force that exerts an upward thrust on the passing board through the top plate 7, generating a fitting pressure between the board and the roller coating mechanism 2.

[0056] In the conveying mechanism 3, the first motor 32 drives the transmission shaft 34 to rotate, the transmission shaft 34 drives the conveyor belt 33 to move, the conveyor belt 33 drives the board placed on the top to move, and the board passes through the roller coating mechanism 2 and the drying mechanism 4 in sequence, realizing the coating of the photosensitive ink on the board surface and the drying of the photosensitive ink tube.

[0057] In the roll coating mechanism 2, the worker pours the photosensitive ink into the ink reservoir 23. Meanwhile, during the process of roll coating the ink, the second motor 22 drives the rotation of the rotating shaft 24, causing the rotating shaft 24 to drive the rotation of the roller 25 inside the ink reservoir 23. During the rotation of the roller 25, the ink scraping plate 26 is driven to rotate, and the ink scraping plate 26 drives the photosensitive ink to move during the rotation, ensuring that there is sufficient photosensitive ink at the bottom of the ink reservoir 23. Meanwhile, after the photosensitive ink reaches the bottom, the agglomerates in the ink are filtered through the arc-shaped filter plate 27, causing the agglomerates to be concentrated on both sides of the bottom under the drive of the ink scraping plate 26. The agglomerated ink enters the inner side of the side folding plate 29 through the square groove at the top of the side folding plate 29. When the sheet passes under the coating roller 28, through contact with the coating roller 28, the coating roller 28 is driven to rotate during the movement, and the photosensitive ink is coated on the surface of the sheet during the rotation, realizing ink coating.

[0058] In the drying mechanism 4, the hot air blower 42 heats the air, causing the hot air to be transmitted through the conduction pipe 47 to the air outlet pipe 45, and the air outlet pipe 45 introduces the hot air into the hot air hood 43, increasing the air pressure inside the hot air hood 43. After the air pressure increases, the hot air is discharged through the slotted plate 44 installed at the bottom rectangular groove. After being discharged, the inclined slot plate 49 fixedly connected by the bottom strip 48 blocks the movement of the hot air. Meanwhile, the hot air is guided to both sides through the inclined through slot of the inclined slot plate 49, blowing the sheet passing under the inclined slot plate 49, and drying the photosensitive ink coated on the top of the sheet.
