Description

Technical Field

[0001] This application belongs to the field of low-temperature co-fired ceramic preparation technology, and particularly relates to a printing-type hole-filling scraper device and a printing-type filling equipment. Background Technology

[0002] There are two main methods for filling holes in low-temperature co-fired ceramics (LTCC): extrusion filling and printing filling. Currently, printing filling is the most commonly used. Printing filling involves applying a paste to one side of a steel plate, then using a screen printer to scrape the paste across the entire steel plate, forcing it through the through-holes in the plate. The pressure of a scraper forces the paste into the through-holes in the green ceramic sheet. Existing scraper devices have a weakness: efficiency and quality cannot be simultaneously achieved. Specifically, to ensure the paste fully fills the through-holes in the green ceramic, the scraper's operating speed must be slowed down. Currently, the maximum scraper speed is 7 mm / s; exceeding this speed results in incomplete filling of the through-holes. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, this application provides a printing-type filling scraper device and a printing-type filling equipment, which can maintain filling quality even when the scraper is running rapidly.

[0004] To achieve the above objectives, the technical solution provided in this application is as follows:

[0005] In a first aspect, this application provides a printing-type hole-filling scraper device, including a base, a clamping block and a scraper, wherein the scraper is arranged between the base and the clamping block, the lower end of the scraper protrudes to form a protrusion, and the bottom wall of the clamping block away from the scraper is provided with a downward baffle, and the protrusion of the scraper, the baffle and the clamping block form an n-shaped groove.

[0006] Optionally, the height of the protrusion of the scraper is 2-3 mm greater than the height of the baffle.

[0007] Optionally, the protrusion of the scraper has a height of 4mm, and the baffle has a height of 2mm.

[0008] Optionally, the baffle is disposed at the front end in the scraper's running direction.

[0009] Optionally, a clamping groove is provided between the base and the clamping block, a top block is engaged in the clamping groove, and the scraper is fixed to the bottom end of the top block.

[0010] Optionally, the protrusion is wider at the top and narrower at the bottom, and the angle between the bottom edge of the protrusion and the horizontal plane is ≤45°.

[0011] Optionally, it also includes adjusting bolts, which pass through the clamping block from top to bottom and are connected to the top block. At least two adjusting bolts are provided, and the at least two adjusting bolts are arranged along the length of the top block. The adjusting bolts are used to reinforce the top block and adjust the height of the protrusion of the scraper.

[0012] Optionally, the scraper is rhomboid in shape, with the pointed end of the rhombus pointing downwards.

[0013] Optionally, the base and the clamping block are fixed together by locking screws.

[0014] On the other hand, this application also provides a printing-type hole-filling device, including the above-mentioned printing-type hole-filling scraper device.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] This application forms an n-shaped groove between the protrusion of the scraper, the baffle, and the clamping block, and makes the height of the protrusion of the scraper greater than the height of the baffle. When the scraper moves forward, the baffle at the front end of the baffle applies a backward force to the slurry, so that the slurry is subjected to multi-directional pressure from the scraper and the baffle in the n-shaped groove, so that the slurry fills the through holes of the green ceramic tile more fully, achieving the purpose of rapid and high-quality filling.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0025] Example 1

[0026] like Figure 1 As shown, a printing-type hole-filling scraper device includes a base 1, a clamping block 2 and a scraper 3. The scraper 3 is arranged between the base 1 and the clamping block 2. The lower end of the scraper 3 protrudes to form a protrusion 31. The bottom wall of the clamping block 2 away from the scraper 3 is provided with a downward baffle 21. An n-shaped groove 4 is formed between the protrusion 31 of the scraper 3, the baffle 21 and the clamping block 2.

[0027] As the scraper 3 moves forward, the slurry 7 is fully agitated within the n-shaped groove 4 between the protrusion 31 of the scraper 3 and the baffle 21 and clamping block 2. Under the multi-directional pressure of the scraper 3 and baffle 21, the slurry 7 is more fully filled into the through holes of the green ceramic tile, achieving the purpose of rapid and high-quality filling.

[0028] Example 2

[0029] The difference between this embodiment and Embodiment 1 is that: Figures 1-4 As shown, the height of the protrusion 31 of the scraper 3 is 2-3 mm greater than the height of the baffle 21, which ensures that the scraper 3 can work smoothly, and the baffle 21 can also act on the slurry 7 to fully fill the slurry 7.

[0030] In this embodiment, the protrusion 31 of the scraper 3 has a height of 4mm, the baffle 21 has a height of 2mm, and the baffle 21 has a width of 3mm.

[0031] The baffle 21 is set at the front end of the scraper 3 in the running direction, so that during the operation of the baffle, more slurry 7 enters the filled through hole under the action of the baffle 21.

[0032] The base 1 and the clamping block 2 are respectively provided with grooves 11, thereby forming a clamping groove between the base 1 and the clamping block 2. The top block 5 is clamped in the clamping groove, and the scraper 3 is fixed to the bottom end of the top block 5.

[0033] It also includes adjusting bolts, which pass through the clamping block 2 from top to bottom and are connected to the top block 5. At least two adjusting bolts are provided, and the at least two adjusting bolts are arranged along the length direction of the top block 5. In this embodiment, five adjusting bolts are provided, and the five adjusting bolts are arranged along the length direction of the top block 5. The top block 5 can be reinforced by adjusting bolts, and the height of the scraper 3 at different positions can be adjusted by rotating the adjusting bolts, thereby adjusting the parallelism of the scraper 3 and keeping the bottom of the scraper 3 straight.

[0034] The protrusion 31 of the scraper 3 is wider at the top and narrower at the bottom, which makes it easy to scrape the slurry 7 into the through hole. In this embodiment, the scraper 3 is rhomboid, with one tip of the rhomboid pointing downwards. The two sides of the upper part of the rhomboid are connected to the top block 5. In order to ensure unidirectional pressure, the angle between the bottom edge of the rhomboid and the horizontal plane is ≤45°.

[0035] A screw hole 6 is provided between the base 1 and the clamping block 2, and a locking screw passing through the screw hole 6 is used for fixing. In this embodiment, four locking screws are arranged horizontally. By providing detachable locking screws, the base 1 and the clamping block 2 can be easily fixed or disassembled, thereby facilitating the installation or removal of the scraper 3. The screw hole 6 is tempered for durability, ensuring that it is not prone to stripping even after repeated disassembly.

[0036] On the other hand, this application also provides a printing-type cavitation filling device, including the aforementioned printing-type cavitation filling scraper device. The printing-type cavitation filling device is installed on a printing-type cavitation filling device, which is typically a printing press 8. Then, paste 7 is applied, and the printing speed is adjusted to perform cavitation filling. The scraper 3 of this application allows the paste 7 to receive multi-directional pressure from the scraper 3 and the baffle 21 within the n-shaped groove 4, enabling the paste 7 to more fully fill the through-holes of the green ceramic tile, achieving rapid and high-quality filling.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
