Abstract

The application discloses a magnetic material box convenient to disassemble, and relates to the technical field of material boxes. In order to distinguish different cover assemblies, the application specifically comprises a material box assembly and a first cover assembly. The material box assembly comprises a material box body, side openings arranged on both sides of the material box body, a top opening arranged on the top of the material box body, and a first magnetic attraction block. A groove is arranged on the material box body close to the top opening. In the case that cover assemblies with similar sizes are mixed, a magnetic structure is added to the existing cover assembly and the material box assembly. The structure has magnetic poles. The material box assembly and the cover assembly with similar sizes are magnetically attracted to each other, and the material box assembly and the cover assembly that do not match repel each other. The application can not only avoid the risk that the cover assemblies with similar sizes are mixed to cause loosening and falling, but also make the combination of the cover assembly and the material box assembly more reliable through magnetic force.

Description

Technical Field

[0001] This invention relates to the field of material box technology, and in particular to a magnetic material box that is easy to assemble and disassemble. Background Technology

[0002] IC carrier boxes in the current packaging industry come in different sizes, such as 63*240mm, 74x240mm, 77.5x240mm, 95*240mm, etc. The IC carrier is usually placed inside the box, and the two sides are covered by a lid to prevent the IC carrier from slipping out.

[0003] Material boxes are generally divided into two parts: the main body of the material box and the lid. Different sizes of material box bodies are equipped with different sizes of lids. When the sizes differ significantly, personnel can distinguish different models with the naked eye, and the lids will not be mixed up.

[0004] However, the sizes of the 74*240 and 77.5*240 caps are very close, differing by only 3.5mm. It is difficult for operators to distinguish them by the naked eye, and the caps are easily mixed up. In actual production, the 77.5mm cap may be mixed up with the 74mm material box body, which may cause the 77.5mm cap to loosen or fall off during the handling of the material box, resulting in the internal products falling out.

[0005] Existing methods of laser engraving and labeling are prone to peeling and wear, making them unsuitable for long-term reuse and unable to withstand long-term wear and tear. Regular label updates are required, resulting in high long-term costs. Furthermore, personnel are required to memorize different types of numbers for identification, making it difficult to avoid human error.

[0006] A search revealed Chinese patent application CN202022883156.2, which discloses an ultra-thin, high-density lead frame cassette carrier. This ultra-thin, high-density lead frame cassette carrier includes a cassette carrier body, a lead frame, and an aluminum cassette cover. A support groove is formed between the two sides of the inner wall of the cassette carrier body, and an installation port is formed at the input end of the support groove. Limiting grooves are formed on both sides of the cassette carrier body, including a protective groove at the bottom of the aluminum cassette cover. The cassette in the above patent has the following shortcomings: during use, when multiple cassette covers of different specifications and minor differences exist, it is difficult to distinguish them, potentially leading to mismatches. Therefore, further improvements are needed. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a magnetically attached material box that is easy to assemble and disassemble.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A magnetic material box that is easy to assemble and disassemble includes a material box assembly and a first cover assembly, wherein the material box assembly includes:

[0010] The material box body has side openings on both sides and a top opening on the top, which is located above the side openings.

[0011] The first magnetic block has a groove near the top opening of the material box body, and the bottom of the first magnetic block is fixed in the groove. The magnetic pole direction of each first magnetic block is consistent.

[0012] The first cover assembly includes:

[0013] The first box lid body has dimensions that are compatible with the two sides of the material box body;

[0014] A first top cover is disposed on the top side wall of the first box cover body, and the size of the first top cover is adapted to the top opening and the groove;

[0015] The second magnetic block is fixed at the bottom of the first top cover plate. The second magnetic block is compatible with the first magnetic block. When the first top cover plate is installed in the groove, the second magnetic block and the first magnetic block attract each other.

[0016] In addition, there is a second cover assembly, which has different specifications from the first cover assembly, and the second cover assembly includes:

[0017] The second box cover body has a second top cover plate provided on one outer wall of the top side of the second box cover body;

[0018] The third magnetic block is fixed at the bottom of the second top cover plate. When the second top cover plate is installed in the groove, the third magnetic block and the first magnetic block repel each other.

[0019] Preferably, the magnetic attraction between the second magnetic block and the first magnetic block is greater than the weight of the first cover assembly.

[0020] Furthermore, the repulsive force between the third magnetic block and the first magnetic block is greater than the gravity of the second cover assembly.

[0021] A further preferred embodiment: slots are provided on both outer walls of the main body of the material box, and inserts adapted to the slots are provided on both sides of the main body of the first box cover, and the main body of the first box cover is detachably inserted into the slots through the inserts.

[0022] As a preferred embodiment of the present invention, the outer wall of one side of the first box cover body is provided with uniformly distributed through holes.

[0023] As a further preferred embodiment of the present invention, ribs are provided on both sides of the top outer wall of the material box body.

[0024] As a further aspect of the present invention: the first cover assembly has an overall L-shaped structure.

[0025] Based on the aforementioned scheme: the first magnetic block, the second magnetic block, and the third magnetic block are made of permanent magnets.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention addresses the issue of mixing lid components of similar size by adding a magnetic structure to existing lid and container components. This structure has magnetic poles, and container and lid components of the same size attract each other magnetically, while mismatched container and lid components repel each other. This not only avoids the risk of loosening or falling off caused by mixing lid components of similar size, but also makes the connection between the lid and container components more reliable through magnetic force, so that they are not easy to fall off even when reversed 180°.

[0028] 2. This invention uses permanent magnets, which not only meet the polarity requirements but also ensure long-term use. They will not fail due to wear and tear or other reasons, and do not require regular replacement, resulting in a high long-term cost advantage.

[0029] 3. By setting slots and inserts, the present invention can limit the movement of the structure during installation, thereby improving the structural robustness. Attached Figure Description

[0034] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0035] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0036] A magnetic material box that is easy to install and remove, such as Figure 1-3 As shown, it includes a material box assembly and a first cover assembly, the material box assembly comprising:

[0037] The material box body 1 has side openings 3 on both sides and a top opening 5 on the top, which is located above the side openings 3.

[0038] The first magnetic block 2 has a groove near the top opening 5 of the material box body 1. The bottom end of the first magnetic block 2 is attached to the groove, and the magnetic pole direction of each first magnetic block 2 is consistent.

[0039] The first cover assembly includes:

[0040] The first box cover body 7 has dimensions that are adapted to the two sides of the material box body 1;

[0041] The first top cover plate 8 is integrally disposed on the top side wall of the first box cover body 7, and the size of the first top cover plate 8 is adapted to the top opening 5 and the groove.

[0042] The second magnetic block 9 is attached to the top of the first top cover plate 8 at its bottom. The second magnetic block 9 is compatible with the first magnetic block 2. When the first top cover plate 8 is installed in the groove, the second magnetic block 9 and the first magnetic block 2 attract each other.

[0043] In addition, there is a second cover assembly, which has different specifications from the first cover assembly, and the second cover assembly includes:

[0044] The second box cover body 13 has a second top cover plate 12 integrally provided on one side of the top outer wall of the second box cover body 13;

[0045] The third magnetic block 14 is fixed to the top of the second top cover plate 12. When the second top cover plate 12 is installed in the groove, the third magnetic block 14 and the first magnetic block 2 repel each other.

[0046] By setting a second magnetic block 9 and a third magnetic block 14 with opposite magnetic poles on the lids of different sizes with small differences, the material box body 1 and the first lid assembly of the same size are magnetically attracted to each other, while the mismatched material box is repelled by the second lid assembly. This not only avoids the risk of loosening and falling off caused by mixing lid assemblies of similar size, but also makes the lid assembly and the material box body 1 more reliably connected by magnetic force, so that it is not easy to fall off even if it is turned upside down 180°.

[0047] To ensure the strength of adsorption; such as Figure 1 , Figure 2 As shown, the magnetic attraction between the second magnetic block 9 and the first magnetic block 2 is greater than the weight of the first cover assembly.

[0048] To improve reliability; such as Figure 1 , Figure 3 As shown, the repulsive force between the third magnetic block 14 and the first magnetic block 2 is greater than the gravity of the second cover assembly.

[0049] To improve installation stability; such as Figure 1 , Figure 2 As shown, slots 4 are provided on both outer walls of the main body 1 of the material box, and inserts 10 adapted to the slots 4 are integrally provided on both sides of the main body 7 of the first box cover. The main body 7 of the first box cover is detachably inserted into the slots 4 through the inserts 10.

[0050] By setting the slot 4 and the insert 10, the structural rigidity can be improved by using the slot 4 and the insert 10 for positioning during installation.

[0051] In addition, the outer wall of one side of the first box cover body 7 is provided with evenly distributed through holes 11.

[0052] To improve practicality; such as Figure 1 As shown, ribs 6 are provided on both sides of the top outer wall of the material box body 1;

[0053] By setting ribs 6, the top surface of the main body 1 of the material box can be more clearly marked, and at the same time, it helps to strengthen the structural integrity.

[0054] To improve reliability; such as Figure 2 As shown, the first cover assembly has an overall L-shaped structure.

[0055] To improve reliability; such as Figure 1 , Figure 2 As shown, the first magnetic block 2, the second magnetic block 9, and the third magnetic block 14 are made of permanent magnets.

[0056] To improve reliability; such as Figure 1 , Figure 2 As shown, the main body 1 of the material box and the main body 7 of the first box cover are made of high temperature resistant material, preferably aluminum.

[0057] In this embodiment, because the second magnetic block 9 and the third magnetic block 14 with opposite magnetic poles are set on the lids of different sizes with small differences, the material box body 1 and the first lid assembly of the same size are magnetically attracted to each other, while the mismatched material box is repelled by the second lid assembly. This not only avoids the risk of loosening and falling off caused by mixing lid assemblies of similar size, but also makes the lid assembly and the material box body 1 more reliably connected by magnetic force, so that it is not easy to fall off even if it is reversed 180°.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
