Description

Technical Field

[0001] This utility model relates to the field of ceramic flat film production and manufacturing, and in particular to a reciprocating spraying equipment for flat ceramic films. Background Technology

[0002] Currently, dried and shaped ceramic blanks are sintered once to form a ceramic flat film substrate. The substrate is then coated with ceramic slurry and sintered a second time to prepare a ceramic flat film.

[0003] Ceramic slurry coating is often carried out by spraying, which involves using compressed air to spray the ceramic slurry in a mist form onto the surface of the ceramic flat film substrate to form a uniform coating.

[0004] In existing technology, the substrate is placed on a conveyor belt and transported to the spraying chamber, where two symmetrical spray guns spray ceramic slurry onto the substrate surface. During this process, the conveyor belt runs continuously while the spray guns remain stationary, allowing the substrate to pass through the atomized surface created by the spray guns, thus forming a coating on the substrate surface. After one side is coated, it needs to be manually flipped over and the above steps repeated to spray the other side.

[0005] Existing technological shortcomings:

[0006] 1. The spraying efficiency is low, and manual flipping is required. The sprayed side is prone to sticking to the conveyor belt after flipping, which can damage the coating.

[0007] 2. Because the spray gun is fixed, the atomization area is limited, and only one sheet can be sprayed at a time;

[0008] 3. The two spray guns are arranged symmetrically, which causes interference in the atomization surface formed during the spraying process, making it difficult to control the uniformity of the coating on the substrate surface. Summary of the Invention

[0045] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0047] like Figure 1 As shown, a reciprocating spraying device for flat ceramic films includes a chain conveyor 1 and a loading area 2, a first spraying chamber 3, a flipping area 4, a second spraying chamber 5, a drying area 6, and an unloading area 7 that are sequentially connected by the chain conveyor 1. It also includes a transport vehicle 9 for transporting flat ceramic film substrates 10 to the loading area 2 and a placement area 8 arranged adjacent to the unloading area 7 for storing flat ceramic film substrates 10.

[0048] like Figure 2 , Figure 3As shown, a bracket 101 for supporting the flat ceramic film substrate 10 is installed on the top of the connecting rod between the chains on both sides of the chain conveyor 1. Movable slide plates 102 are installed at both ends of the top of the bracket 101. A strip hole 103 is provided in the center of the slide plate 102. A clamping bolt 104 is threaded to both ends of the top of the bracket 101. The slide plate 102 slides along the clamping bolt 104 through the strip hole 103. A clamping washer 105 is provided between the clamping bolt 104 and the slide plate 102. The slide plate 102 is clamped and fixed by the clamping bolt 104 and the clamping washer 105. A support plate 106 is fixed to the outer end of the slide plate 102. A silicone sleeve 107 is provided on the top of the support plate 106. The flat ceramic film substrate 10 is supported by the support plate 106.

[0049] The slide plate 102 can move on the bracket 101 to adjust the distance between the two support plates 106, thereby adapting to flat ceramic film substrates 10 of different lengths. The silicone sleeve 107 can prevent scratches on the flat ceramic film substrate 10 and is not affected during the drying process.

[0050] like Figure 4 As shown, the upper plate area 2 is provided with an upper plate mechanism for transferring the flat ceramic film substrate 10 from the transport vehicle 9 to the support 101. The upper plate mechanism includes a portal frame 201 located on both sides of the chain conveyor 1 in the upper plate area 2. A first vertical linear slide 202 is embedded in the upper part of the inner wall on both sides of the portal frame 201. A transverse linear slide 203 is installed between the sliders of the first vertical linear slide 202. A suction cup frame 204 is installed on the slider of the transverse linear slide 203. Several pairs of suction cups 205 are provided on both sides of the bottom of the suction cup frame 204. The flat ceramic film substrate 10 is adsorbed and fixed by the suction cups 205 and transferred to the support plate 106.

[0051] The loading process of the flat ceramic film substrate 10 is as follows: The flat ceramic film substrate 10 is placed on the transport trolley 9 and transported to the loading area 2. At this time, the transport trolley 9 is located directly below the loading mechanism. The suction cup 205 moves downward to a position 1-3 mm above the flat ceramic film substrate 10 under the action of the first vertical linear slide 202. The negative pressure adsorption is activated to adsorb the flat ceramic film substrate 10 onto the suction cup 205. After adsorption is completed, it returns to the initial position. At this time, the horizontal linear slide 203 moves to transport the flat ceramic film substrate 10 above the support 101. Then, under the action of the first vertical linear slide 202, it moves downward to place the flat ceramic film substrate 10 at the support 101 and the negative pressure adsorption is turned off. Finally, the loading mechanism returns to the initial position.

[0052] like Figures 5-7As shown, the first spraying chamber 3 and the second spraying chamber 5 are respectively equipped with spraying mechanisms for spraying the surface of the flat ceramic film substrate 10. Each spraying mechanism includes a shielding plate 301, a transverse linear motor module 302, a longitudinal linear motor module 303, a spray gun bracket 304, and a spray gun 305. The shielding plate 301 is installed on the inner walls of both sides of the first spraying chamber 3 and the second spraying chamber 5 to shield the chain of the chain conveyor 1. The longitudinal linear motor module 303 is installed on the upper part of the inner walls of both sides of the first spraying chamber 3 and the second spraying chamber 5, and the transverse linear motor module 305 is installed on the upper part of the inner walls of both sides of the first spraying chamber 3 and the second spraying chamber 5. Linear motor module 302 is mounted on the slider of longitudinal linear motor module 303, spray gun bracket 304 is mounted on the slider of transverse linear motor module 302, spray gun 305 is mounted on spray gun bracket 304, and spray gun 305 sprays the first surface of flat ceramic film substrate 10 twice in the first spray chamber 3 and sprays the second surface of flat ceramic film substrate 10 twice in the second spray chamber 5. The spraying trajectory is distributed in a serpentine pattern along multiple flat ceramic film substrates 10 in the first spray chamber 3 and the second spray chamber 5, and the two spraying trajectories are opposite.

[0053] First-side coating process: The flat ceramic film substrate 10 is located at the support 101, which moves towards the first coating chamber 3 under the action of the chain conveyor 1. Upon entering the first coating chamber 3, the operation stops. At this time, the spray gun 305 begins coating the flat ceramic film substrate 10 under the combined action of the transverse linear motor module 302 and the longitudinal linear motor module 303, as shown in Figure 6. Figure 7 The spraying operation shown requires two coats to ensure the uniformity of the coating on the board surface. The arrows indicate the trajectory of the spray gun.

[0054] Second-side coating: After the flipping is completed, the flat ceramic film substrate 10 continues to move towards the second coating chamber 5 under the action of the chain conveyor 1. When it enters the second coating chamber 5, the operation stops, and the first-side coating process is repeated to complete the two-side coating operation of the flat ceramic film substrate 10.

[0055] like Figures 8-11As shown, the flipping area 4 is equipped with a flipping mechanism for flipping the flat ceramic film substrate 10 by 180°. The flipping mechanism includes a rectangular frame 401 located on both sides of the chain conveyor 1 within the flipping area 4. Guide rails 402 are provided on the inner walls of the front and rear side rods of the rectangular frame 401. A slide block 403 is slidably mounted on the guide rails 402. A triangular support block 404 is provided on the inner side of the slide block 403. A horizontal plate 405 is provided on the top of the support block 404 on the same side. A driving horizontal plate 405 is provided on the top of the rectangular frame 401. The first electric cylinder 423 for lifting has a mounting plate 406 at the bottom center of the horizontal plate 405. A motor 407 is mounted inside one mounting plate 406, and a rotating shaft 408 is rotatably connected to the inside of the other mounting plate 406. A connecting plate 409 is fixedly connected to the opposite face of the motor 407 spindle and the rotating shaft 408. Square tubes 410 are fixedly connected to the front and rear ends of the opposite face of the connecting plate 409. First fixed seats 411 are fixedly connected to the bottom sides of the square tubes 410. U-shaped frames 412 are fixedly connected to the front and rear sides of the first fixed seats 411. The bottom ends of the square tube 410 are fixed with second fixed seats 413. The bottom of adjacent first fixed seats 411 and second fixed seats 413 are fixed with fixed blocks 414. A guide rod 415 is fixed between two adjacent fixed blocks 414. A movable block 416 is slidably sleeved on the guide rod 415. A pair of racks 417 sliding in opposite directions are slidably installed at the bottom of the U-shaped frame 412. A fixed plate 418 connects the movable block 416 and the corresponding rack 417. The bottom of the square tube 410 is rotatably connected to the two racks 417. 17 meshing gears 419, a rack 417 with a moving rod 420 at the top, a square tube 410 with a sliding hole 421 corresponding to the moving rod 420, a second electric cylinder 422 installed at the top of the square tube 410, the telescopic rod of the second electric cylinder 422 is fixedly connected to the moving rod 420, a C-shaped clamping groove 424 is fixedly connected between two opposing movable blocks 416, a sponge 425 is installed in the clamping groove 424, and the flat ceramic film substrate 10 is clamped and fixed by the sponge 425 on the clamping groove 424.

[0056] Flipping process: After one side is coated, the flat ceramic film substrate 10 continues to move towards the flipping area 4 under the action of the chain conveyor 1. When it enters the flipping area 4, it stops running. At this time, the horizontal plate 405 moves downward under the action of the first electric cylinder 423.

[0057] Parallel to the flat ceramic film substrate 10, the second electric cylinder 422 drives the moving rod 420 to move, at which time the corresponding rack 417 moves, thereby driving the gear 419 to rotate, which in turn drives another rack 417 to move. At this time, the two racks 417 move in opposite directions, driving the two clamping grooves 424 to move towards the flat ceramic film substrate 10, thereby driving the sponge 425 to move closer to the flat ceramic film substrate 10. When the two come into contact, the sponge 425 will continue to move towards the flat ceramic film substrate 10 by 2-4mm, ensuring that the sponge 425 can stably clamp the flat ceramic film substrate 10. After the clamping action is completed, the flat ceramic film substrate 10 is driven to move upward and return to the initial position. Then, under the action of the motor 407, it rotates 180° to flip the flat ceramic film substrate 10. After the flipping action is completed, it moves downward again. When the flat ceramic film substrate 10 contacts the bracket 101, it stops. Then, under the action of the second electric cylinder 422, the sponge 425 releases the flat ceramic film substrate 10, and the flipping mechanism returns to the initial position to complete the flipping process.

[0058] The drying zone 6 is equipped with a drying mechanism for drying the flat ceramic film substrate 10. The drying mechanism includes a hot air circulating dryer with the temperature controlled within the range of 70~100℃.

[0059] Drying process: After both sides of the flat ceramic film substrate 10 are coated, it enters the drying area and the coating is dried under the action of a hot air circulating dryer at a temperature of 70~100℃.

[0060] like Figure 12 , Figure 13 As shown, a loading trolley 801 is placed in the loading area 8, and an unloading mechanism is provided in the unloading area 7 for transferring the flat ceramic film substrate 10 from the support 101 to the loading trolley 801. The unloading mechanism includes unloading brackets 701 located on both sides of the chain conveyor 1 in the unloading area 7, and the unloading brackets 701 extend into the loading area 8. A longitudinal linear slide 702 is installed on the inner side of the unloading brackets 701. A second vertical linear slide 703 is installed on the slider of the longitudinal linear slide 702, and the top of the second vertical linear slide 703 slides along the top of the unloading bracket 701. A crossbeam 704 is installed between the sliders of the second vertical linear slide 703. A connecting frame 705 is installed at the bottom of the crossbeam 704. Unloading hanging grooves 706 in the shape of a horizontal U are installed on both sides of the bottom of the connecting frame 705. The flat ceramic film substrate 10 is transferred by being suspended through the unloading hanging grooves 706.

[0061] Unloading and Placing Process: After drying, the substrate enters the unloading area 7. At this time, the chain conveyor 1 stops running, and the unloading trough 706 is located at the end of the chain conveyor 1. Under the action of the longitudinal linear slide 702, it moves towards the chain conveyor 1. At this time, the flat ceramic film substrate 10 is located in the unloading trough 706. Under the action of the second vertical linear slide 703, it moves upward to lift the flat ceramic film substrate 10, completing the separation of the flat ceramic film substrate 10 from the support 101. Then, under the action of the longitudinal linear slide 702, it moves towards the plating cart 801. When the flat ceramic film substrate 10 moves to directly above the plating cart 801, it stops moving. At this time, under the action of the second vertical linear slide 703, it moves downward. After the flat ceramic film substrate 10 contacts the plating support on the plating cart 801, it continues to move downward for 1-2 mm to complete the unloading operation. Then, it detaches from the plating cart 801 to continue the next unloading. The plating cart 801 then transfers the flat ceramic film substrate 10.

[0062] This invention eliminates the need for manual flipping by setting up a flipping mechanism, thus avoiding coating defects caused by manual flipping. The support 101 allows for suspended spraying of the ceramic flat film, preventing contact with the conveyor belt and reducing film defects, thereby improving coating quality. Furthermore, multiple ceramic flat films are placed in the spraying chamber, resulting in high spraying efficiency, allowing multiple films to be sprayed simultaneously. The reciprocating spraying process ensures uniform coating on the ceramic flat film surface, covering the substrate surface without any dead corners. Each spraying chamber uses only one spray gun 305, avoiding mutual interference caused by multiple spray guns operating simultaneously, thereby improving coating uniformity.
