This cutting wheel has the characteristics of high precision and high durability, can be repeatedly coated and used, and is a key component in the processing of monocrystalline silicon.

[0003] However, with the rapid development of the monocrystalline silicon processing industry, the use of cutting wheels is also increasing.

[0041] In order to make the technical personnel in this field better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods; Figure 1-Figure 8 To understand.

[0042] The utility model provides a packaging structure of a cutting wheel 900 used in the cutting and squaring process of single crystal silicon machining, which can effectively prevent the cutting wheel 900 from collision and wear during transportation.

[0043] The up and down orientations in this article refer to the packaging structure being in normal use, with the side pointing to the ground being down, and the opposite being up, in its height direction.

[0044] In the production process of monocrystalline silicon, the machining, cutting and squaring process is an indispensable part. In this process, cutting tools such as long diamond wire and circular wire are widely used. They perform fine cutting operations on monocrystalline silicon rods through high-speed rotation and precise control. In order to achieve this process, an important auxiliary equipment is the cutting wheel 900, which is usually made of an aluminum substrate and coated with polyurethane material on the outer layer. This cutting wheel 900 has the characteristics of high precision and high durability, can be repeatedly coated and used, and is a key component in the processing of monocrystalline silicon.

[0045] However, with the rapid development of the monocrystalline silicon processing industry, the use of cutting wheels 900 is also increasing. During the use of cutting wheels 900, the polyurethane coating will gradually wear out, and when the service life is reached, it needs to be re-coated. In this process, the packaging and transportation of cutting wheels 900 has become an important issue. Traditional cutting wheel 900 packaging methods mostly use cartons for small amounts of individual packaging, but due to the heavy aluminum substrate, paper packaging boxes cannot provide sufficient support and protection, resulting in cutting wheels 900 being easily squeezed and damaged during transportation.

[0046] In addition, the traditional packaging method of cutting wheels 900 also has problems such as messy placement and unclear quantity counting. In the warehouse, cutting wheels 900 are usually stacked randomly, which not only increases the difficulty of management, but also easily causes unnecessary damage to the cutting wheels 900 during storage. At the same time, the inability to accurately count the quantity also brings inconvenience to the company's production plan;

[0047] In summary, the existing packaging method of cutting wheel 900 has the following problems:

[0048] First, the material of the packaging box cannot meet the protection requirements of the cutting wheel 900, which may easily cause the cutting wheel 900 to be squeezed and damaged during transportation.

[0049] Second, the packaging method is disorganized, which is not conducive to the storage and management of the cutting wheel 900.

[0050] Third, it is impossible to accurately count the number of cutting wheels 900, which brings inconvenience to the company's production plan. In order to solve at least one of the above technical problems, the present application provides a packaging structure for cutting wheels 900 used in the truncation and squaring processes of single crystal silicon machining.

[0051] like Figure 1 and Figure 8 As shown, Figure 1 It is a schematic diagram of the structure of the cutting wheel 900 in the embodiment of the utility model; Figure 8 It is an external view of the packaging structure; the packaging structure is used to store and transfer the cutting wheel 900, which is a ring-shaped disc structure. A circular through hole 901 is opened in the middle of the cutting wheel 900 to form an inner ring 903 and an outer ring 904; axially protruding bosses 902 are provided on both axial end faces of the cutting wheel 900, the boss 902 is close to the inner ring 903 and is arranged around the through hole 901, and the table surface of the boss 902 extends axially beyond the rest of the cutting wheel 900 to form the most protruding part of the corresponding side end face.

[0052] In a specific embodiment, Figure 2-Figure 7 As shown, Figure 2 is a partial schematic diagram of the packaging structure, omitting part of the side panel assembly 200; Figure 3 is a partial schematic diagram of the packaging structure, omitting the cover plate assembly 300; Figure 4 It is a partial schematic diagram of the packaging structure, omitting the cover plate assembly 300 and part of the side plate assembly 200; Figure 5 yes Figure 2 A side cross-sectional view of the packaging structure, cut along the length direction of the packaging structure; Figure 6 yes Figure 2 A side cross-sectional view of the packaging structure, cut along the width direction of the packaging structure; Figure 7 yes Figure 2The packaging structure includes a bottom plate assembly 100, a side plate assembly 200 and a cover plate assembly 300. The side plate assembly 200 is vertically arranged on the bottom plate assembly 100 and surrounds a receiving cavity 400. The cover plate assembly 300 is covered at the mouth of the receiving cavity 400 to close and open the receiving cavity 400. The packaging structure adopts a hard material with high structural strength and can be reused to save resources. For example, the packaging structure adopts a wooden structure, and the wooden packaging structure can effectively prevent the cutting wheel 900 from being squeezed and damaged during transportation. Of course, in addition to the wooden structure, The packaging structure can also be made of metal, hard plastic, etc.; in order to prevent the cutting wheel 900 from shaking and wearing in the packaging structure during transportation, the packaging structure also includes a stopper 500, which is arranged perpendicular to the bottom plate assembly 100 and extends along the height direction of the packaging structure, and the stopper 500 is penetrated through the inner ring 903 of the cutting wheel 900; that is, the cutting wheel 900 is sleeved on the outside of the stopper 500, thereby forming a radial limit on the stopper 500, which can prevent the stopper 500 from shaking during transportation. The packaging structure may cause shaking and wear in the packaging structure; in addition, the packaging structure is also used for daily storage of the cutting wheel 900. When the cutting wheel 900 is used, it can be inserted into the stopper 500; optionally, one or more cutting wheels 900 are sleeved on the stopper 500. Since the cutting wheel 900 has an axially protruding boss 902, when multiple cutting wheels 900 are stacked in the axial direction, the bosses 902 of adjacent cutting wheels 900 form a pressure in the axial direction, so that contact and wear between the outer rings 904 of the axially adjacent cutting wheels 900 can be avoided; through such In this way, each stopper 500 can be equipped with a certain number of cutting wheels 900. In the daily management of the cutting wheels 900, the stopper 500 can also be used to calculate the number of cutting wheels 900, so as to facilitate the management of the cutting wheels 900; of course, multiple stoppers 500 can also be provided in each packaging structure. In the example shown in the figure, six stoppers 500 are provided, but other numbers can also be provided. In this way, the number of cutting wheels 900 that can be stored in a single packaging structure is increased, and the packaging efficiency of the cutting wheels 900 is improved.

[0053] In one embodiment, the top of the stopper 500 directly or indirectly abuts against the bottom surface of the cover assembly 300. Optionally, the packaging structure further includes a positioning plate 600 arranged in the horizontal direction, and the positioning plate 600 is connected to the tops of at least two adjacent stoppers 500; the cover assembly 300 presses against the upper surface of the positioning plate 600. That is, a positioning plate 600 is arranged on the bottom surface of the cover assembly 300, and the positioning plate 600 has a certain thickness so as to extend downward from the bottom surface of the cover assembly 300 to the top of the stopper 500; of course, the positioning plate 600 may not be arranged, but the bottom surface of the cover assembly 300 may be directly used to press against the upper surface of the stopper 500; in this way, the cover assembly 300 and the bottom plate assembly 100 can press against the top and bottom of the stopper 500, thereby forming a stopper for the stopper 500, thereby increasing the structural strength of the stopper 500 during transportation.

[0054] In the above-mentioned embodiment, the positioning plate 600 and the top of the stopper are positioned in the horizontal direction; this not only facilitates the positioning and installation between the cover plate assembly 300 and the top of the stopper 500, but also limits the stopper 500 in the horizontal direction, further preventing the stopper 500 from shaking in the horizontal direction; in one example, combined with Figure 2 and Figure 5 , the protective sleeve 502 exceeds the top of the support column 501 in the height direction and forms a positioning hole 503 with the top surface of the support column 501; the lower surface of the positioning plate 600 is provided with a positioning protrusion 601, and the positioning protrusion 601 is plugged into the positioning hole 503; in another example, the top of the support column 501 extends out from the protective sleeve 502; the lower surface of the positioning plate 600 is provided with a positioning groove and is plugged into the top of the support column 501.

[0055] In other embodiments, a plurality of pads 700 are further included, and the pads 700 are fixedly arranged on the upper side of the base plate assembly 100; the bottom end of the stopper 500 is fixed to the surface of the pad 700 away from the base plate assembly 100; the pad 700 is smaller than the radial dimension of the outer ring 904 of the cutting wheel 900, and is greater than or equal to the dimension of the bottom end of the stopper 500; specifically, the bottom end of the stopper 500 has a mounting plate 501b, the mounting plate 501b is a circular structure, the pad 700 is a strip-shaped structure, and the width of the pad 700 is adapted to the radial dimension of the mounting plate 501b, that is, equal to or greater than the radial dimension of the mounting plate 501b. The radial dimension of the mounting disk 501b ensures the connection strength between the stopper 500 and the base plate assembly 100; at the same time, the pad 700 is smaller than the radial dimension of the outer ring 904 of the cutting wheel 900, thereby reducing the contact area between the table surface of the boss 902 and the pad 700, and at the same time can support the cutting wheel 900 located at the lower side at a certain height to prevent the cutting wheel 900 from being worn; optionally, the extension direction of each positioning plate 600 is perpendicular or parallel to the extension direction of the pad 700, thereby limiting the relative distance between adjacent stoppers 500, and further enhancing the structural strength of the stopper 500.

[0056] In the above-mentioned embodiment, the stopper 500 includes a support column 501 and a protective sleeve 502. The support column 501 extends in the height direction, and its bottom end is fixedly connected to the base plate assembly 100. The protective sleeve 502 is arranged around the outer wall of the support column 501; the wall surface of the inner ring 903 of the cutting wheel 900 is in contact with the protective sleeve 502; the protective sleeve 502 is made of a flexible material, and the protective sleeve 502 is made of, for example, rubber, sponge nylon, etc.; the outer diameter of the protective sleeve 502 can change with the change of the radial size of the inner ring 903 of the cutting wheel 900, thereby effectively positioning the position of the cutting wheel 900, and at the same time protecting the hole wall of the through hole 901 of the cutting wheel 900 from scratches and extrusion.

[0057] The main structure 501a of the support column 501 extends in the height direction, and the support column 501 is a cylindrical structure, a square column structure, etc. The bottom end of the main structure 501a also extends outward to form a mounting plate 501b, and the mounting plate 501b is fitted with the base plate assembly and fixedly connected to the base plate assembly. The mounting plate 501b is circular or square, and the mounting plate 501b is arranged parallel to the base plate assembly 100. The bottom end surface of the main structure 501a is located at the center of the mounting plate 501b. The main structure 501a and the mounting plate 501b are an integrated structure or a split structure, and technical personnel in this field can choose by themselves; the mounting plate 501b and the base plate assembly 100 can be fixedly connected by nails. Optionally, a latching protrusion 701 is further provided on the pad 700, and a latching recess 501b-1 is further provided on the lower surface of the mounting plate 501b away from the main structure 501a of the support column 501. The latching protrusion 701 and the latching recess 501b-1 are engaged with each other to form a positioning when the stopper 500 and the pad 700 are assembled.

[0061] By setting the stopper 500, the cutting wheel 900 is prevented from shaking or squeezing during transportation, and the cutting wheel 900 is prevented from being damaged. The stopper 500 specifically includes a support column 501 and a protective sleeve 502. The support column 501 can effectively separate the cutting wheel 900, and the protective sleeve 502 can protect the inner hole of the cutting wheel 900 from being scratched. The number of support columns 501 can be reduced or increased, depending on the number of cutting wheels 900 used on site. The outer diameter of the protective sleeve 502 can be enlarged or reduced, and can be replaced at any time, depending on the inner diameter of the cutting wheel 900 used on site.
