Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box for diamonds. Background Technology

[0002] Existing packaging boxes for diamonds are commonly used for the safe storage and transportation of diamond wafers. Diamond wafers are defined as single-crystal diamond films grown by chemical vapor deposition (CVD) or high temperature and high pressure (HPHT), usually with silicon, sapphire, or other substrates as substrates, and with a thickness generally between 10 and 500 micrometers.

[0003] To this end, Chinese utility model patent ZL202220999341.4 (authorization announcement number CN217075263U) discloses "A Diamond Wafer Packaging Box". The packaging box includes a buffer cavity and a fixing film. The fixing film includes a fixing layer, an adsorption layer and an electrostatic layer that are separately arranged. The diamond wafer is adsorbed between the electrostatic layer and the fixing layer by electrostatic adsorption to prevent the diamond wafer from shaking inside the packaging box when the packaging box is subjected to external force during transportation.

[0004] However, besides diamond wafers, diamond flakes are also widely used in many high-end fields, such as semiconductor manufacturing and microelectronics. Unlike diamond wafers, diamond flakes are defined as thin slices cut from natural diamond or synthetic blocks (such as polycrystalline blocks grown by the HPHT method). The thickness range is relatively wide (from micrometers to millimeters), but ultra-thin slices (such as 1–100 micrometers) are more common. They are thinner than diamond wafers. As mentioned above, several diamond wafers are electrostatically adsorbed between the electrostatic layer and the fixing layer. However, since the processed diamond flakes are natural single crystals, their thickness is even thinner. If the above-mentioned packaging box is used for storage or transportation, the surface of the processed diamond flakes is relatively smooth. If it is placed on the surface of the electrostatic layer, it will be adsorbed on the surface of the electrostatic layer and is not easy to remove. It is difficult to remove the diamond flakes with common tools such as tweezers or by hand. Therefore, it is necessary to find a packaging box suitable for storing or transporting diamond flakes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a packaging box suitable for the storage and transportation of diamonds, especially suitable for diamond sheets with a thickness between 50-100 micrometers, in light of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The packaging box for diamonds includes a box body, characterized in that: the box body is provided with an adsorption element that adsorbs diamond flakes to be used by means of negative pressure, the negative pressure value generated by the adsorption element is less than the pressure value at which the diamond flakes to be used break, and the box body is also provided with an action element that acts on the adsorption element, and under the state in which at least part of the action element is squeezed, the adsorption of the diamond flakes to be used by the adsorption element can be released.

[0007] Diamond flakes for use typically come in various sizes and thicknesses, each with different crushing pressure values. To accommodate different sizes of diamond flakes, preferably, at least two actuating elements are provided, each with its corresponding adsorption element. Each adsorption element independently corresponds to the negative pressure value of the diamond flake to be adsorbed. The housing has an insertion part for inserting the actuating elements, allowing each actuating element, along with its corresponding adsorption element, to be selectively inserted into the insertion part. Thus, when storing or transporting diamond flakes with lower crushing pressure values, an actuating part with an adsorption element of lower negative pressure can be selected to prevent the diamond flakes from breaking during adsorption; conversely, when transporting or storing diamond flakes with higher crushing pressure values, an actuating part with an adsorption element of higher negative pressure can be selected to ensure the diamond flakes are securely adsorbed.

[0008] Furthermore, each of the acting members is a box structure with an open top and a closed bottom. A convex portion is provided at the center of the bottom of the box structure, and the adsorbent is a convex edge located around the vertex of the convex portion and opening upward. The top of the convex edge is higher than the vertex of the convex portion. The height difference H1 between the top and the bottom of the convex edge and the height difference H2 between the vertex of the convex portion and the bottom of the convex edge satisfy: 1 / 5H1 < H2 < 1 / 2H1. The acting member as a whole is made of a flexible material, and its box structure can play a buffering role during the transportation of the待用 diamond thin sheet, avoiding the待用 diamond thin sheet from hitting the arm of the box and breaking; the convex portion at the center of the bottom of the box structure has three functions: First, it can be locally squeezed to act on the adsorbent to switch the adsorbent between adsorbing the待用 diamond thin sheet and releasing the adsorption of the待用 diamond thin sheet; Second, it is arranged at the bottom of the待用 diamond thin sheet and can provide buffering for the待用 diamond thin sheet to protect the待用 diamond thin sheet; Third, the protrusion is provided so that when the待用 diamond thin sheet is in the box, the peripheral edge of its lower surface is in a suspended state, forming a space for a clip, forceps or finger to伸入, so as to facilitate the removal of the待用 diamond thin sheet from the box. The adsorbent is a convex edge located around the vertex of the convex portion and opening upward. In this way, when the acting member is squeezed, the edge of the convex edge can deform radially outward to expel the air inside the convex edge and form a negative pressure to adsorb the待用 diamond thin sheet. Since the bottom of the convex edge extends upward from the periphery of the vertex of the convex portion and the vertex of the convex portion is higher than the top of the convex edge, the air inside the convex edge cannot be completely discharged and is only in a negative pressure state with a pressure lower than the atmospheric pressure. When the acting member is squeezed again, the convex portion moves upward under the squeezing force and squeezes the remaining air inside the convex edge, so that the air pressure inside the convex edge gradually increases. At this time, the adsorption force of the adsorbent on the diamond thin sheet gradually weakens to disappear. As the convex portion moves further upward, its vertex will be higher than the convex edge and push the diamond thin sheet upward, thus facilitating the removal of the diamond thin sheet with common tools such as clips and forceps or directly by hand. If the vertex of the convex portion is too high, it will limit the radial outward deformation of the convex edge and cannot discharge enough air to generate enough negative pressure to adsorb the待用 diamond thin sheet. If the vertex of the convex portion is too low, there is too little remaining air inside the convex edge in the adsorption state, and the internal and external air pressure difference when the acting member is squeezed again is not enough to解除 the negative pressure state between the待用 diamond thin sheet C and the convex edge. Therefore, in the state without adsorbing the diamond thin sheet, the height difference H1 between the top and the bottom of the convex edge and the height difference H2 between the vertex of the convex portion and the bottom of the convex edge are限定为: 1 / 5H1 < H2 < 1 / 2H1.

[0009] It should be noted that there are some terms like "待用 diamond thin sheet" in the original text which might need to be further clarified in the context to ensure more accurate translation. Here, I've translated it as is based on the given text.Furthermore, the convex edge is a sloping edge that gradually slopes outward from bottom to top, and the sloping edge forms an angle α with the bottom of the frame structure, where 10°≤α≤30°. If the angle α is too small, less air can be expelled from the convex edge, making it impossible to generate sufficient negative pressure; if the angle α is too large, it is difficult to ensure that the edge of the convex edge deforms radially outward during the compression action. If the sloping edge undergoes irregular deformation, it will be impossible to generate negative pressure between it and the diamond sheet to be used. Therefore, the angle α is limited to 10°≤α≤30°.

[0010] To facilitate the compression of at least a portion of the actuating element, preferably, an opening is provided on the bottom of the housing, through which at least a portion of the protrusion of the actuating element is exposed and can be compressed. Thus, an operator can compress the actuating element from the opening, causing it to act on the adsorption element, switching between adsorbing and releasing diamond flakes.

[0011] Furthermore, the device also includes a cover located at the top of the housing and rotatably connected to the housing. The cover has a cushioning element for protecting the diamond sheet to be used. A gap is formed between the cushioning element and the adsorption element to accommodate the diamond sheet. The cushioning element on the cover provides cushioning to the upper surface of the diamond sheet to be used, preventing it from colliding with the cover and breaking during transport. The gap provides space for the diamond sheet to be placed, and ideally, the height of the gap should be the same as the thickness of the diamond sheet.

[0012] To improve the safety of transporting and storing diamond sheets, the system preferably includes a locking structure that secures the cover to the box. This prevents the cover from rotating relative to the box during transport, thus protecting the diamond sheets and ensuring safe transport.

[0013] As one locking structure, the locking structure includes a first magnet disposed on the box body and a second magnet disposed on the lid body that cooperates with the first magnet. When the lid body is closed, the first magnet and the second magnet attract each other and lock the lid body onto the box body. The magnetic attraction method allows for one-handed opening and closing, making it convenient to open the lid body. In addition, the locking structure can also adopt other methods to lock the lid body onto the box body, such as a snap-fit ​​or a latch and keyhole.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The packaging box uses an adsorption element to adsorb diamond flakes to prevent them from shaking inside the box during transportation. Due to their thinness and brittleness, the negative pressure value generated by the adsorption element is set to be less than the pressure value that would break the diamond flakes, thereby avoiding breakage of the diamond flakes when they are adsorbed due to stress concentration. The action element can change the adsorption state of the adsorption element, allowing it to switch between adsorbing and de-adsorbing the diamond flakes, avoiding the problem of the diamond being difficult to remove from the box. The diamond flakes can be removed directly with tweezers, tweezers, or fingers. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-7The diagram shows a preferred embodiment of the present invention. The packaging box of this embodiment is suitable for the storage and transportation of single-crystal diamond flakes C with a thickness between 50-100 micrometers. The packaging box includes a box body 1 and a cover 4 disposed on the top of the box body 1 and rotatably connected to the box body 1. The box body 1 is provided with an adsorption element 2 that adsorbs the diamond flakes C to be used by means of negative pressure, and an action element 3 acting on the adsorption element 2. The negative pressure value generated by the adsorption element 2 is less than the pressure value at which the diamond flakes C to be used break, and the adsorption element 3, under at least partial compression, can release the adsorption of the diamond flakes C to be used by the adsorption element 2.

[0026] Since the diamond flakes C to be used are usually not limited to a single size, but come in various specifications with different sizes and thicknesses, and the crushing pressure values ​​of diamond flakes C of different specifications are different, an adsorption element 2 capable of generating different negative pressure values ​​is needed to suit diamond flakes C of different specifications. In this embodiment, multiple actuating elements 3 are provided, each actuating element 3 is provided with its own corresponding adsorption element 2, and each adsorption element 2 independently corresponds to the negative pressure value of the diamond flake C to be adsorbed. The housing 1 is provided with an insertion part 11 for inserting the actuating element 3, and the actuating element 3 together with its corresponding adsorption element 2 can be selectively inserted into the insertion part 11. When storing or transporting diamond flakes C with a low breaking pressure value, the insertion part 11 with a lower negative pressure value is selected to prevent the diamond flakes C from breaking during adsorption. Conversely, when storing or transporting diamond flakes C with a higher breaking pressure value, the insertion part 11 with a higher negative pressure value is selected to ensure that the diamond flakes C are stably adsorbed. Figure 2The diagram shows the selected actuating element 3 in its disassembled state from the box body 1. As can be seen, the actuating element 3 is made of flexible material and is a frame structure 31 with an open top and closed bottom. This flexible frame structure 31 acts as a buffer during the transport of the diamond sheet C, preventing it from shattering upon impact with the arm of the box body 1. A protrusion 32 is located at the center of the bottom of the frame structure 31, and the adsorption element 2 is a convex edge located outside the apex of the protrusion 32 with its opening 12 facing upwards. By setting the adsorption element 2 as a convex edge outside the apex of the protrusion 32 with its opening 12 facing upwards, when the actuating element 3 is squeezed, the bottom of the convex edge moves towards the edge, causing the edge of the convex edge to deform radially outwards, expelling air from the convex edge and creating a negative pressure to adsorb the diamond sheet C. Since the bottom of the convex edge extends upwards from the apex of the protrusion 32, and the apex of the protrusion 32 is higher than... The top of the convex edge means that the air inside the convex edge cannot be completely expelled, and it is only in a negative pressure state with an air pressure lower than atmospheric pressure. When the action member 3 is squeezed again, the convex part 32 is squeezed upward by the squeezing force, which squeezes the air remaining in the convex edge and causes the air pressure inside the convex edge to gradually increase. At this time, the adsorption force of the adsorption member 2 on the diamond sheet C gradually weakens and disappears. As the convex part 32 moves further upward, its apex will be higher than the convex edge and push the diamond sheet C upward, so that it is convenient to remove the diamond sheet C with common tools such as tweezers or by hand.

[0027] For details, please refer to the following: Figure 6 and 7 In this embodiment, when the packaging box is not holding the diamond sheet C, the top of the convex edge is higher than the apex of the convex portion 32. To ensure that the convex edge can hold the diamond sheet C and can release the holding state by squeezing the actuating member 3 again, the height difference H1 between the top and bottom of the convex edge and the height difference H2 between the apex of the convex portion 32 and the bottom of the convex edge in this embodiment are: H2 = 2 / 5H1. When the squeezing member 3 releases the holding of the diamond sheet C, the apex of the convex portion 32 rises to H2 > H1 to push the diamond sheet C out. The convex edge is a sloping edge that gradually slopes outward from bottom to top, and the sloping edge forms an angle α with the bottom of the frame structure 31. To ensure that the convex edge can hold the diamond sheet C, the angle α in this embodiment is 25°. To facilitate at least a portion of the squeezing member 3, an opening 12 is provided on the bottom of the box body 1, and at least a portion of the convex portion 32 of the actuating member 3 is exposed to the opening 12 so that at least a portion of the actuating member 3 can be squeezed. Thus, the operator can squeeze the actuating element 3 from the opening 12, causing the actuating element 3 to act on the adsorption element 2, switching it between adsorbing the diamond sheet C to be used and desorbing the diamond sheet C to be used. The squeezing change of the actuating element 3 can be referenced. Figure 6 .

[0028] In addition, the cover 4 is provided with a buffer 5 for protecting the diamond sheet C to be used. A gap 6 is formed between the buffer 5 and the adsorption member 2 to accommodate the diamond sheet C. The buffer 5 on the cover 4 is designed to cushion the upper surface of the diamond sheet C, preventing it from colliding with the cover 4 and breaking during transport. The gap 6 provides space for the diamond sheet C; in this embodiment, the height of the gap 6 is the same as the thickness of the diamond sheet C. The box 1 is also provided with a first magnet 13, and the cover 4 is provided with a second magnet 41 that cooperates with the first magnet 13. When the cover 4 is closed, the first magnet 13 and the second magnet 41 magnetically attract each other, locking the cover 4 onto the box 1. Locking the cover 4 onto the box 1 by magnetic attraction prevents the cover 4 from rotating relative to the box 1 during transport, thus protecting the diamond sheet C and ensuring transport safety.

[0029] In summary, the method of using the packaging box in this embodiment is as follows:

[0030] A. Open cover 4, as follows Figure 3 As shown, the diamond sheet C to be used is placed on the convex edge, and the diamond sheet is moved downwards to contact the adsorption element 2, and the action element 3 is squeezed from the opening 12, as shown. Figure 4 As shown, the air inside the convex edge is partially expelled, adsorbing the diamond sheet C to be used. At this time, the adsorption is completed by releasing the actuating element 3, and the cover 4 is closed, as shown. Figure 5 As shown;

[0031] B. Open the cover 4, and squeeze the actuating element 3 from the opening 12, as follows: Figure 6-7 As shown, due to the compression of the residual air inside the protrusion by the protrusion 32, the air pressure inside the protrusion gradually increases. At this time, the adsorption force of the adsorbent 2 on the diamond sheet C gradually weakens until it disappears. As the protrusion 32 moves further upward, its apex will be higher than the protrusion and push the diamond sheet C upward, so that it is convenient to remove the diamond sheet C with common tools such as tweezers or by hand.

[0032] Example 2

[0033] The packaging box structure in this embodiment is the same as that in Embodiment 1, except that the functional component 3 and the adsorption component 2 are smaller in size. Figure 8 As shown. The active element 3 and the adsorption element 2 in this embodiment are suitable for diamond sheets C that are smaller in size and have lower crushing pressure values.
