Description

Technical Field

[0001] This invention relates to the field of aluminum substrate manufacturing, and more specifically to a method for preparing an ultra-tough alumina substrate. Background Technology

[0002] The aluminum substrate mainly consists of three key layers: copper foil circuit, insulating dielectric, and aluminum substrate. This design makes the aluminum substrate particularly suitable for electronic applications that require good heat dissipation, and it is mainly used in high-power LED lighting, power modules, and other occasions that require good heat dissipation.

[0003] Existing aluminum substrate processing and cleaning methods still have the following problems: When existing spray cleaning equipment performs spraying operations, the impact force of the sprayed water jet on the aluminum substrate may cause the aluminum substrate to move, thereby affecting the subsequent processing and use of the aluminum substrate.

[0004] Therefore, it is necessary to invent a method for preparing an ultra-tough alumina substrate to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method for preparing an ultra-tough alumina substrate, in order to solve the problem mentioned in the background art that the impact force of the sprayed water jet on the aluminum substrate during the spraying operation of the existing spray cleaning device may cause the aluminum substrate to move, thereby affecting the subsequent processing and use of the aluminum substrate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spray cleaning device for preparing ultra-tough alumina substrates, comprising an outer frame, a flow guide frame installed at the bottom of the outer frame, and a support leg fixedly installed at the bottom of the flow guide frame; a conveyor belt is installed inside the outer frame, and a spray box is arranged above the conveyor belt; the bottom of the spray box is mounted on the top of the outer frame; a feed inlet is provided on one side of the outer frame, and a dust sweeping component is movably installed inside the feed inlet; and a correction rod is movably installed inside the outer frame through an angle adjustment component.

[0007] Preferably, the dust removal assembly includes a U-shaped plate that is movably inserted into the feed inlet via an insertion component, and bristles are fixedly installed at the lower end of the U-shaped plate. The aluminum substrate moves through the gap between the bottom wall of the feed inlet and the bristles, and the bristles lightly touch the surface of the aluminum substrate. In this way, when the aluminum substrate is conveyed and passes through the bristles, the bristles clean the floating dust on the aluminum substrate, ensuring that the impurities inside the spraying liquid are reduced during subsequent recycling of the cleaning liquid spray.

[0008] Preferably, the insertion component includes insertion holes provided on the U-shaped plate and the outer frame, and an insertion rod is movably inserted into the insertion hole. A threaded sleeve is threadedly connected to the threaded end of the insertion rod. The insertion component also includes an annular block fixedly connected to one side of the threaded sleeve. The annular block is rotatably connected to an annular groove provided on the U-shaped plate, and the annular groove is not connected to the insertion hole. In this way, after the insertion rod is matched with the insertion hole on the U-shaped plate and the outer frame, the threaded sleeve is twisted to achieve a tight threaded connection with the insertion rod, ensuring the installation connection between the U-shaped plate and the feed inlet.

[0009] Preferably, the insertion component further includes a limiting block fixedly connected to the inner wall of the insertion hole on one side of the U-shaped plate, and the limiting block is slidably connected to the limiting groove provided inside the insertion rod. The tail end of the limiting groove is closed, ensuring smooth movement between the insertion rod and the insertion hole without detaching from the insertion hole, avoiding the loss of the insertion rod and increasing installation costs, while simplifying the overall installation process.

[0010] Preferably, the correction rod is provided with a transverse channel, and the inner wall of the transverse channel is attached to the outer wall of the conveyor belt to achieve a sliding connection. The edge of the correction rod is attached to the outer side of the aluminum substrate to achieve a sliding connection, so that the two sets of correction rods limit the position of the aluminum substrate during the conveying process and prevent the aluminum substrate from moving during the subsequent spraying process.

[0011] Preferably, the angle adjustment component includes a square cavity disposed on the outer frame, and a short shaft is rotatably mounted inside the square cavity, and one end of the correction rod is fixedly fitted onto the outer wall of the short shaft.

[0012] Preferably, the angle adjustment component further includes a movable groove disposed inside the short shaft, and a rotating rod is elastically connected inside the movable groove by a spring. The upper end of the rotating rod is fixedly connected to a rotating disk, which is engaged with a locking slot on the outer frame. When the rotating disk and the locking slot are matched and connected, the rotating rod cannot rotate, causing the short shaft to be unable to rotate, which further prevents the angle of the correction rod from being adjusted. Later, after the rotating disk separates from the locking slot, rotating the rotating rod adjusts the short shaft to rotate, thereby adjusting the angle of the correction rod and facilitating the movement and limiting of the correction rod for aluminum substrates of different sizes.

[0013] Preferably, the movable groove is composed of a columnar groove and a vertical strip groove connected to the columnar groove. The inner diameter of the columnar groove is larger than the outer diameter of the rotating rod. A spring is movably fitted on the outer ring of the rotating rod. The upper and lower ends of the spring are fixedly connected to the side blocks that are fixedly connected to the top wall of the columnar groove and the lower side walls of the rotating rod, respectively. The outer wall of the side block is in contact with the inner wall of the vertical strip groove to achieve a sliding connection. In this way, moving the rotating disk upwards causes the rotating disk to move and match with the locking groove to achieve a matching connection or separation, which facilitates the synchronous rotation of the short shaft.

[0014] Preferably, the outer ring of the rotary dial is provided with a plurality of semi-cylindrical blocks arranged in a ring at equal angles, and the semi-cylindrical blocks are matched and connected with the semi-cylindrical grooves provided inside the mounting slot. This allows the angle of the semi-cylindrical blocks on the rotary dial to be adjusted by rotating the rotary dial within a small range, so that the semi-cylindrical blocks are matched and connected with the semi-cylindrical grooves provided inside the mounting slots. The mounting slots are open, which allows the rotary dial to be moved upward through the mounting slots to separate the rotary dial from the mounting slots.

[0015] This invention also provides a method for preparing an ultra-tough alumina substrate, using the aforementioned spray cleaning apparatus for preparing an ultra-tough alumina substrate, with the following specific operating steps:

[0016] Step 1: Pretreatment. The aluminum panel is heated at a specific temperature and kept at that temperature, and then slowly cooled. This process eliminates residual stress inside the material, improves the plasticity and toughness of the aluminum panel, and makes its strength reach 900-1100.

[0017] Step 2: Aluminum plate cleaning. The aluminum plate is polished, cleaned, degreased, and deoxidized to ensure that the surface of the aluminum plate is clean and flat.

[0018] Step 3: Coat the surface of the aluminum plate with an insulating material to form an insulating layer;

[0019] Step 4: By covering the insulating layer with photoresist, and then creating the circuit pattern through exposure, development, etching and other steps;

[0020] Step 5: Clean, dry, and cut the processed aluminum substrate again to ensure the dimensional accuracy of the subsequent aluminum substrates.

[0021] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0022] 1. This invention enables the conveying of aluminum substrates via a conveyor belt. When the aluminum substrate enters the lower end of the spray box, the liquid sprayed from the spray box cleans the surface of the aluminum substrate. At the same time, two sets of correction rods limit the position of the aluminum substrate on the conveyor belt, ensuring that the aluminum substrate will not move when subjected to the impact force of the liquid sprayed inside the spray box. This ensures the stability of the aluminum substrate conveying, resulting in better cleaning effect and a more comprehensive cleaning range.

[0023] 2. By pushing the dial upwards, the dial can be separated from the mounting slot, facilitating the synchronous rotation of the short shaft. The dial lever rotates the short shaft, adjusting the angle of the correction rod. This allows the correction rod to move and limit the movement of aluminum substrates of different sizes. When the dial is matched and connected to the mounting slot, the dial lever cannot rotate, preventing the short shaft from rotating. This further prevents the correction rod angle from adjusting, ensuring better limiting effect of the correction rod on the aluminum substrate. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This invention provides, for example Figure 1-8The spray cleaning device for preparing ultra-tough alumina substrate shown includes an outer frame 1, a flow guide frame 2 installed at the bottom of the outer frame 1, and a support leg 3 fixedly installed at the bottom of the flow guide frame 2. A conveyor belt 4 is installed inside the outer frame 1, and a spray box 5 is arranged above the conveyor belt 4. The bottom of the spray box 5 is mounted on the top of the outer frame 1. A feed inlet 6 is provided on one side of the outer frame 1, and a dust sweeping component 7 is movably installed inside the feed inlet 6. A correction rod 8 is movably installed inside the outer frame 1 through an angle adjustment component 9.

[0037] In use, the conveyor belt 4 transports the aluminum substrate. When the aluminum substrate enters the lower end of the spray box 5, the liquid sprayed from the spray box 5 cleans the surface of the aluminum substrate. At the same time, two sets of correction rods 8 limit the position of the aluminum substrate on the conveyor belt 4, ensuring that the aluminum substrate will not move when it is subjected to the impact force of the liquid sprayed inside the spray box 5, thereby ensuring the stability of the aluminum substrate transport.

[0038] The dust removal assembly 7 includes a U-shaped plate 701 that is movably inserted into the feed inlet 6 via an insertion component. A brush bristle 702 is fixedly installed at the lower end of the U-shaped plate 701. The aluminum substrate moves through the gap between the bottom wall of the feed inlet 6 and the brush bristle 702. The brush bristle 702 lightly touches the surface of the aluminum substrate. When the aluminum substrate is conveyed and passes through the brush bristle 702, the brush bristle 702 cleans the floating dust on the aluminum substrate, ensuring that the impurities inside the spraying liquid are reduced during subsequent recycling of the cleaning liquid spray.

[0039] To ensure the movable connection between the U-shaped plate 701 and the feed inlet 6, the insertion component includes an insertion hole 704 provided on the U-shaped plate 701 and the outer frame 1. An insertion rod 703 is movably inserted into the insertion hole 704, and a threaded sleeve 705 is threadedly connected to the threaded end of the insertion rod 703. The smooth inner wall of the insertion hole 704 allows for the smooth movement of the threaded insertion rod 703. The insertion component also includes an annular block 706 fixedly connected to one side of the threaded sleeve 705, and the annular block 706 is connected to the annular sleeve 705 provided on the U-shaped plate 701. The groove 707 enables a rotatable connection, and the annular groove 707 is not connected to the insertion hole 704. The insertion component also includes a limiting block 708 fixedly connected to the inner wall of the insertion hole 704 on one side of the U-shaped plate 701. The limiting block 708 is slidably connected to the limiting groove 709 provided inside the insertion rod 703. The tail end of the limiting groove 709 is closed, ensuring that the insertion rod 703 and the insertion hole 704 are smoothly connected but not disengaged from the insertion hole 704. This avoids the insertion rod 703 being lost later, increasing installation costs, and simplifies the overall installation process.

[0040] This allows the insert rod 703 to be moved, passing through the insert hole 704 on the outer frame 1 and matching the insert hole 704 on the U-shaped plate 701. Twisting the threaded sleeve 705 then secures the insert rod 703 to the threaded sleeve 705, ensuring a tight threaded connection between the U-shaped plate 701 and the upper part of the feed inlet 6. When the brush bristles 702 and the U-shaped plate 701 need to be replaced, twisting the threaded sleeve 705 in the opposite direction moves the insert rod 703, which is threaded to the sleeve 705, within the insert hole 704, causing it to move away from the insert hole 704 on one side of the outer frame 1 and the U-shaped plate 701. When the insert rod 703 is only inside one insert hole 704 with a limiting block 708, it is easy to move the U-shaped plate 701 downwards. The soft brush bristles 702 ensure smooth downward movement of the U-shaped plate 701, facilitating replacement of the U-shaped plate 701.

[0041] The correction rod 8 is provided with a transverse channel, and the inner wall of the transverse channel is attached to the outer wall of the conveyor belt 4 to achieve a sliding connection. The edge of the correction rod 8 is attached to the outer side of the aluminum substrate to achieve a sliding connection. This allows the two sets of correction rods 8 to limit the position of the aluminum substrate during conveying, preventing the aluminum substrate from moving during subsequent spraying processing.

[0042] The angle adjustment component 9 includes a square cavity 901 disposed on the outer frame 1, and a short shaft 902 is rotatably mounted inside the square cavity 901, and one end of the correction rod 8 is fixedly fitted on the outer wall of the short shaft 902.

[0043] The angle adjustment component 9 also includes a movable groove 907 disposed inside the short shaft 902, and a rotating rod 903 is elastically connected inside the movable groove 907 via a spring 908. The movable groove 907 is composed of a columnar groove and a vertical strip groove connected to the columnar groove. The inner diameter of the columnar groove is larger than the outer diameter of the rotating rod 903. The outer ring of the rotating rod 903 is movably fitted with the spring 908. The upper and lower ends of the spring 908 are fixedly connected to the top wall of the columnar groove and the two lower side walls of the rotating rod 903, respectively. The outer wall of the side block 906 is attached to the inner wall of the vertical strip groove to achieve a sliding connection. The rotating disk 904 fixedly connected to the upper end of the rotating rod 903 is engaged with the locking groove 905 provided on the outer frame 1.

[0044] The outer ring of the rotary dial 904 is provided with several semi-cylindrical blocks arranged in a ring at equal angles. The semi-cylindrical blocks are matched and connected with the semi-cylindrical grooves provided inside the mounting slot 905. This allows the angle of the semi-cylindrical blocks on the rotary dial 904 to be adjusted by rotating the rotary dial 904 within a small range, so that the semi-cylindrical blocks are matched and connected with the semi-cylindrical grooves provided inside the mounting slot 905. The mounting slot 905 is open, which allows the rotary dial 904 to be moved upward through the mounting slot 905 to separate the rotary dial 904 from the mounting slot 905.

[0045] By pushing the dial 904 upwards, the dial 904 can be matched and connected or separated from the mounting slot 905, which facilitates the synchronous rotation of the short shaft 902. When the dial 904 is matched and connected with the mounting slot 905, the rotating rod 903 cannot rotate, which prevents the short shaft 902 from rotating, and further prevents the angle of the correction rod 8 from being adjusted. Later, after pushing the dial 904 upwards to separate it from the mounting slot 905, rotating the rotating rod 903 adjusts the short shaft 902 to rotate, which allows the angle of the correction rod 8 to be adjusted, making it convenient for the correction rod 8 to move and limit the movement of aluminum substrates of different sizes.

[0046] This invention also provides a method for preparing an ultra-tough alumina substrate, using the aforementioned spray cleaning apparatus for preparing an ultra-tough alumina substrate, with the following specific operating steps:

[0047] Step 1: Pretreatment. Heat the aluminum panel at 400 degrees Celsius and keep it at that temperature for 10 hours, then cool it slowly. This process eliminates residual stress inside the material, improves the plasticity and toughness of the aluminum panel, and makes its strength reach 900-1100.

[0048] Step 2: Aluminum plate cleaning. The aluminum plate is polished, cleaned, degreased, and deoxidized to ensure that the surface of the aluminum plate is clean and flat.

[0049] Step 3: Coat the surface of the aluminum plate with an insulating material to form an insulating layer;

[0050] Step 4: By covering the insulating layer with photoresist, and then creating the circuit pattern through exposure, development, etching and other steps;

[0051] Step 5: Clean, dry, and cut the processed aluminum substrate again to ensure the dimensional accuracy of the subsequent aluminum substrates.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
