AI Technical Summary
During the manufacturing process of ceramic components, air flow during vacuum packaging causes the edges of the ceramic component bars to slide out of the laminate easily, causing dislocation, which in turn leads to indentation and deformation of the inner electrode.
A laminate for ceramic components is designed with a thickness greater than or equal to 1.4 mm, and its material includes elements such as carbon, silicon, manganese, phosphorus, and alloys. The area of the laminate is greater than the area of the bar block to ensure that the orthoprojection edge of the bar block is located in the orthoprojection of the laminate.
The laminated edges of the bar block are effectively avoided, which reduces the risk of uneven edges of the bar block, reduces the possibility of internal electrode deformation, and significantly improves the quality of ceramic components.

Abstract

Technical Field
[0001] The present application relates to the technical field of ceramic components, and in particular to a laminate for ceramic components. Background Art
[0002] In the manufacturing process of ceramic components such as multi-layer ceramic chip capacitors (MLCC), multiple ceramic diaphragms with internal electrodes are stacked to form a bar, which is a ceramic component bar. The ceramic component bar is then vacuum-encapsulated before being placed in a press for lamination. Vacuum encapsulation means placing the ceramic component bar in a packaging bag, setting a laminate between the packaging bag and the upper and lower surfaces of the ceramic component bar, and then vacuuming the packaging bag to form a vacuum condition.
[0003] However, when the packaging bag is vacuumed, air flow can cause the edge of the ceramic component block to easily slide out of the laminate, resulting in misalignment between the ceramic component block and the laminate. As a result, during lamination, indentations are generated on the ceramic component block at the misalignment, causing deformation of the internal electrode of the ceramic component block.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.
[0024] The present application provides a laminate for ceramic components, the laminate is used to press a bar block, the edge of the orthographic projection of the bar block from the laminate toward the bar block is located within the orthographic projection of the laminate, the thickness of the laminate is greater than or equal to 1.4 mm, and the material of the laminate includes at least one of carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, tungsten, vanadium, cobalt, nickel, iron and alloys thereof.
[0025] In the present application, in the direction from the laminate toward the bar block, the edge of the orthographic projection of the bar block is set to be located within the orthographic projection of the laminate, so that the area of the laminate is larger than the area of the bar block, so as to avoid the situation where the air flow easily causes the edge of the bar block to slide out of the laminate when the packaging bag is vacuumed, thereby causing the bar block and the laminate to be misaligned, thereby avoiding indentations on the bar block at the misaligned position during lamination, that is, reducing the risk of uneven edges of the bar block, and thus reducing the risk of deformation of the internal electrode of the bar block.
[0026] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first structure of the laminate and the bar block provided by the present application; Figure 2 yes Figure 1Schematic diagram of the structure at the laminate A in . The present application provides a laminate 10 for ceramic components, the laminate 10 is used to press the bar block 20, and in the direction from the laminate 10 to the bar block 20, the edge of the orthographic projection of the bar block 20 is located within the orthographic projection of the laminate 10, that is, the area of the laminate 10 is greater than the area of the bar block 20. The thickness d of the laminate 10 is greater than or equal to 1.4 mm. Specifically, the thickness d of the laminate 10 can be 1.4 mm, 1.6 mm, 1.8 mm, 2.4 mm, 2.7 mm or 3.5 mm, etc. The material of the laminate 10 includes at least one of carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, tungsten, vanadium, cobalt, nickel, iron and alloys thereof.
[0027] In the present application, in the direction from the laminate 10 toward the bar block 20, the edge of the orthographic projection of the bar block 20 is set to be located within the orthographic projection of the laminate 10, so that the area of the laminate 10 is larger than the area of the bar block 20, so as to avoid the air flow causing the edge of the bar block 20 to slide out of the laminate 10 when the packaging bag is vacuumed, thereby causing the bar block 20 to be misaligned with the laminate 10, thereby avoiding indentations or scratches on the bar block 20 at the misaligned position during lamination, that is, reducing the risk of uneven edges of the bar block 20, and the indentation rate or scratch rate can be reduced from more than 60% to less than 2%, thereby reducing the risk of deformation of the internal electrode of the bar block 20.
[0028] In the present application, the thickness d of the laminate 10 is set to be greater than or equal to 1.4 mm to avoid the risk of cracking of the laminate 10 during lamination, thereby reducing the risk of uneven edges of the bar block 20 and reducing the risk of deformation of the internal electrode of the bar block 20.
[0029] In one embodiment, the distance between the edge of the orthographic projection of the bar block 20 and the edge of the orthographic projection of the laminate 10 in the direction from the laminate 10 to the bar block 20 is greater than or equal to 0.2 mm. Specifically, the distance between the edge of the orthographic projection of the bar block 20 and the edge of the orthographic projection of the laminate 10 in the direction from the laminate 10 to the bar block 20 can be 0.2 mm, 0.25 mm, 0.34 mm, 0.43 mm, 0.9 mm or 1.3 mm, etc. Preferably, the distance between the edge of the orthographic projection of the bar block 20 and the edge of the orthographic projection of the laminate 10 is 0.2-0.5 mm.
[0030] In the present application, in the direction from the laminate 10 toward the bar block 20, the distance between the edge of the orthographic projection of the bar block 20 and the edge of the orthographic projection of the laminate 10 is set to be greater than or equal to 0.2 mm, so as to further avoid the situation where the air flow causes the edge of the bar block 20 to slide out of the laminate 10 when the packaging bag is vacuumed, thereby causing the bar block 20 and the laminate 10 to be misaligned, and further avoid the bar block 20 from having indentations at the misaligned position during lamination, that is, further reducing the risk of unevenness or protrusions on the edge of the bar block 20, and further reducing the risk of deformation of the internal electrode of the bar block 20.
[0031] In one embodiment, the laminate 10 has a first surface 101 and a second surface 102 that are relatively disposed, the first surface 101 has first corners 103 that are spaced apart, the second surface 102 has second corners 104 that are spaced apart, and the first corners 103 and the second corners 104 are both arc corners, that is, the corners of the laminate 10 are arc-shaped.
[0032] In the prior art, after the laminate 10 and the bar block 20 are placed in a packaging bag for packaging, the laminate 10 has sharp corners, which makes it easy for the laminate 10 to pierce the packaging bag. If the corners are right angles, the packaging bag is prone to being scratched due to the sharpness of the right angles. As a result, during subsequent operations, the vacuum abnormality alarm rate can be as low as 50% or more, thereby causing subsequent operations to be unable to proceed normally.
[0033] In the present application, the corners of the laminate 10 are set to be arc angles to reduce the risk of the packaging bag being punctured by the corners of the laminate 10, so as to reduce the vacuum abnormality alarm rate to less than 0.5% during subsequent operations, thereby ensuring the progress of subsequent operations and shortening the production cycle of the block 20.
[0034] In one embodiment, in the direction from the laminate 10 toward the bar block 20 , the orthographic projection of the arc angle does not overlap with the orthographic projection of the bar block 20 , that is, the portion of the laminate 10 provided with the arc angle does not overlap with the bar block 20 .
[0035] In the present application, part of the laminate 10 with arc corners is set not to overlap with the bar block 20, so as to further avoid the situation where the air flow causes the edge of the bar block 20 to slide out of the laminate 10 when the packaging bag is vacuumed, thereby causing the bar block 20 and the laminate 10 to be misaligned, and further avoid the appearance of indentations on the bar block 20 at the misaligned position during lamination, that is, further reducing the risk of unevenness or protrusions on the edge of the bar block 20, and further reducing the risk of deformation of the internal electrode of the bar block 20.
[0036] In one embodiment, the radius r of the arc angle is greater than or equal to 0.45 mm. Specifically, the radius r of the arc angle can be 0.45 mm, 0.56 mm, 0.67 mm, 0.79 mm or 0.82 mm.
[0037] In the present application, the radius r of the arc angle is set to be greater than or equal to 0.45 mm to further reduce the risk of the packaging bag being punctured by the corners of the laminate 10 .
[0038] See also Figure 3 , Figure 3 This is a second structural schematic diagram of a laminate and a block provided by the present application. It should be noted that the difference between the second structure and the first structure is that: the laminate 10 includes a first steel plate 110 and a second steel plate 120, the first steel plate 110 and the second steel plate 120 are arranged opposite to each other, and the block 20 is placed between the first steel plate 110 and the second steel plate 120, that is, the laminate 10 is composed of two membranes, not one; the first steel plate 110 has a first corner 103 on one side away from the second steel plate 120, and the second steel plate 120 has a second corner 104 on one side away from the first steel plate 110, and the first corner 103 and the second corner 104 are arc angles, that is, the corners of the first steel plate 110 and the second steel plate 120 away from the block 20 are set to arc angles, and the other structures are the same as the first structure, which will not be repeated here.
[0039] In the present application, the laminate 10 is configured to be composed of a first steel plate 110 and a second steel plate 120, and the corners of the first steel plate 110 away from the second steel plate 120 and the corners of the second steel plate 120 away from the first steel plate 110 are set to be rounded angles to reduce the risk of unevenness or protrusions on the edge of the block 20, and at the same time reduce the risk of the packaging bag being punctured by the corners of the laminate 10.
[0040] In one embodiment, one side of the first steel plate 110 close to the second steel plate 120 and one side of the second steel plate 120 close to the first steel plate 110 have a third corner 105, and the third corner 105 is a right angle, that is, the corners of the first steel plate 110 and the second steel plate 120 close to the block 20 are right angles.
[0041] In the present application, the corners of the first steel plate 110 and the second steel plate 120 near the block 20 are set to right angles to reduce the risk of unevenness or protrusions on the edge of the block 20, and reduce the risk of the packaging bag being punctured by the corners of the laminate 10.
[0042] See also Figure 4 , Figure 4 This is a third structural schematic diagram of a laminate and a block provided by the present application. It should be noted that the third structure is different from the second structure in that:
[0043] The laminate 10 further includes a third steel plate 130, which is located between the first steel plate 110 and the second steel plate 120, and the corners of the third steel plate 130 are right angles. The other structures are the same as the second structure, and will not be described again.
[0044] In the present application, a third steel plate 130 is arranged between the first steel plate 110 and the second steel plate 120, and the corners of the third steel plate 130 are set to right angles to reduce the risk of unevenness or protrusions on the edge of the block 20. At the same time, because the third steel plate 130 is located in the middle and does not contact the packaging bag, the risk of the packaging bag being punctured by the corners of the laminate 10 is reduced.
[0045] In one embodiment, in the direction from the first steel plate 110 toward the second steel plate 120, the edge of the orthographic projection of the third steel plate 130 is located within the orthographic projections of the first steel plate 110 and the second steel plate 120, and the edge of the orthographic projection of the block 20 is located within the orthographic projection of the third steel plate 130, so as to further reduce the risk of the third steel plate 130, whose corners are set at right angles, scratching the packaging bag, thereby reducing the risk of the packaging bag being punctured by the corners of the laminate 10.
[0046] Optionally, the laminate 10 may further include a fourth steel plate, a fifth steel plate, a sixth steel plate or an eighth steel plate, etc., which are arranged between the first steel plate 110 and the second steel plate 120, and are not limited here.

Any equivalent structural or equivalent process transformations made using the contents of the specification and drawings of the present application, such as the mutual combination of technical features between the embodiments, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
