Description

Technical Field

[0001] This utility model relates to the semiconductor field, and in particular to a dicing knife packaging box. Background Technology

[0002] Dividing blades are commonly used for cutting wafers. In terms of shape, a dicing blade is a thin, disc-shaped sheet structure. Currently, dicing blades are packaged in plastic or acrylic boxes. During transportation, the dicing blade is prone to friction with the packaging box, generating static electricity. This can cause the thin dicing blade to adhere to the inside of the packaging box, making it difficult to remove or easy to break during removal. Utility Model Content

[0003] The purpose of this utility model is to provide a dicing knife packaging box that makes it easy to handle the dicing knife.

[0004] To achieve the above objectives, this utility model proposes a dicing knife packaging box for packaging dicing knives, including a top plate and a bottom cover that are rotatably connected. The top plate is rotatable for opening or closing the bottom cover. When the top plate and the bottom cover are closed, the side of the top plate facing the bottom cover is provided with a first abrasive part. The bottom cover is provided with a receiving cavity for placing the dicing knife, and a second abrasive part is provided at the bottom of the receiving cavity. The first abrasive part and the second abrasive part are respectively located at positions corresponding to the two end faces of the dicing knife.

[0005] Preferably, the dicing blade has a disc-shaped structure, including a base and a cutting edge disposed on the outer edge of the base, with a first abrasive portion and a second abrasive portion disposed at positions corresponding to the base of the dicing blade.

[0006] Preferably, the first and second abrasive portions are intermittent or continuous annular structures.

[0007] Preferably, the roughness of the first abrasive portion and the second abrasive portion is Ra = 0.5-2 μm.

[0008] Preferably, the top plate is shaped to fit the receiving cavity, and when the top plate is fastened to the lower cover, the top plate and the receiving cavity are tightly closed.

[0009] Preferably, the bottom of the accommodating cavity is provided with a positioning element for fixing the dicing blade.

[0010] Preferably, the positioning element is a convex ring whose shape is adapted to the inner hole of the dicing blade.

[0011] Preferably, the top plate has a through hole with a shape adapted to the positioning member at the position of the positioning member, and the height of the positioning member satisfies the following condition: when the top plate is fastened to the lower cover, the positioning member cooperates with the top plate to make the accommodating cavity in a closed state.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) In the present invention, when the top plate and the bottom cover of the dicing knife packaging box are fastened together, a first frosted part and a second frosted part are respectively provided on the side of the top plate near the accommodating cavity and the bottom of the accommodating cavity, and the first frosted part and the second frosted part correspond to the two end faces of the dicing knife respectively, so that the dicing knife adsorbed on the bottom of the accommodating cavity and the top plate due to static electricity during transportation can be more easily removed.

[0014] (2) The roughness of the first abrasive part and the second abrasive part is Ra=0.5-2μm, which reduces the wear of the coating on the surface of the dicing blade substrate by the first abrasive part and the second abrasive part while preventing electrostatic adsorption.

[0016] Figure 2 This is a schematic diagram of the dicing blade in a preferred embodiment of the present invention. Detailed Implementation

[0017] The embodiments of this utility model 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 intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] See Figure 1 As shown, in a preferred embodiment of this utility model, this embodiment provides a dicing knife packaging box for packaging dicing knives. Figure 2 A schematic diagram of a dicing knife that can be used in the packaging box of the dicing knife is shown. The dicing knife 1 is disc-shaped and includes a base 11, an inner hole 12 disposed at the center of the base 11, and a cutting edge 13 at the edge of the base 11.

[0020] The dicing blade packaging box includes a top plate 2 and a bottom cover 3 that are rotatably connected. The top plate 2 can rotate relative to the bottom cover 3 to open or close the bottom cover 3. The bottom cover 3 has a receiving cavity 31 for placing the dicing blade 1. The shape of the top plate 2 is adapted to the receiving cavity 31. In this embodiment, a square receiving cavity 31 is used; therefore, the top plate 2 is square in size and its shape matches the opening shape of the receiving cavity 31. In other embodiments, a circular or other suitable shaped receiving cavity 31 can also be used.

[0021] During transportation, static electricity generated by friction can attract the thin dicing blade 1 to the bottom of the top plate 2 and the receiving cavity 31, making the dicing blade 1 prone to damage during removal. With the top plate 2 and lower cover 3 closed, the side of the top plate 2 facing the lower cover 3 has a first abrasive part 23, and the bottom of the receiving cavity 31 has a second abrasive part 34. The first abrasive part 23 and the second abrasive part 34 are respectively positioned corresponding to the two end faces of the dicing blade 1 and the base 11 of the dicing blade 1. This avoids contact between the first abrasive part 23 and the second abrasive part 34 and the blade 13, preventing wear on the blade 13 and allowing for better removal of the dicing blade 1, thus preventing damage to the dicing blade 1. In this embodiment, the first abrasive portion 23 and the second abrasive portion 34 are continuous annular structures. Of course, in other embodiments, an intermittent annular structure or a first abrasive portion 23 and / or a second abrasive portion 34 with other shapes can also be used, as long as it can achieve the separation of the dicing blade 1 from the top plate 2 and the bottom of the receiving cavity 31 without abrading the cutting edge 13 of the dicing blade 1. The roughness of the first abrasive portion 23 and the second abrasive portion 34 is Ra = 0.5-2μm. Within this roughness range, the first abrasive portion 23 and the second abrasive portion 34 can easily achieve the separation of the dicing blade 1 from the top plate 2 and the bottom of the receiving cavity 31, and at the same time, it can also avoid scratches on the part of the dicing blade 1 that contacts the first abrasive portion 23 or the second abrasive portion 34.

[0022] The side opposite to the rotatable connection side of the top plate 2 and the lower cover 3 is the opening side. The top plate 2 has a first locking part on the opening side, and the lower cover 3 has a second locking part corresponding to the position of the first locking part. The top plate 2 and the lower cover 3 are connected by a snap-fit ​​on the opening side. In this embodiment, the first locking part is a locking block 21 extending outward from the edge of the top plate, and the second locking part is a groove 32 whose size is closely matched with the locking block 21. This ensures that when the top plate 2 and the lower cover 3 are closed, the groove 32 can lock the locking block 21 and limit its position, thereby further limiting the degree of closure of the top plate 2. This prevents the top plate 2 from excessively extending into the receiving cavity 31, facilitating the loading of the dicing knife packaging box without squeezing the dicing knife 1 inside the packaging box when the dicing knife 1 is loaded to the maximum extent. In other embodiments, other snap-fit ​​connection methods can also be used. Because the dicing blade 1 is relatively thin, in addition to avoiding compression during transportation, it is also necessary to fix the dicing blade 1 inside the packaging box to prevent damage caused by circumferential impacts during transportation. In this embodiment, a positioning member 33 with a shape adapted to the inner hole of the dicing blade is provided in the receiving cavity 31 of the packaging box. In this embodiment, the positioning member 33 is a convex ring. When packaging the dicing blade 1, the inner hole 12 is aligned with the positioning member 33 to achieve the effect of fixing the dicing blade 1 in the receiving cavity 31. In other embodiments, a soft anti-collision strip can also be provided in the receiving cavity 31 to achieve the purpose of buffering circumferential impacts, but such packaging is more complex and cannot be manufactured by one-piece molding. In order to reduce the cost of the dicing blade packaging box, the top plate 2 is provided with a through hole 22 with a shape adapted to the positioning member 33 at the position of the positioning member 33. The through hole 22 and the positioning member 33 need to cooperate to seal the receiving cavity 31 to prevent sand and other impurities from entering the receiving cavity 31 and reducing the yield of the dicing blade 1. Therefore, the height of the positioning element 33 satisfies the following condition: when the top plate 2 is fastened to the lower cover 3, the positioning element 33 cooperates with the upper cover 2 to make the accommodating cavity 31 closed.

[0023] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
