DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. In addition, the "in one embodiment" or "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such articles. In the absence of further restrictions, the elements defined by the sentence "including a ..." do not exclude the existence of other identical elements in the article including the elements.

[0027] refer to Figures 1 to 7 As shown, the utility model provides a slice arranging mechanism and a slice rewinding device.

[0028] In the first aspect, the utility model proposes a slice organizing mechanism, which includes a first organizing component 1 and a second organizing component 2 arranged at intervals, and a dividing axis 3 arranged between the first organizing component 1 and the second organizing component 2 and can be close to or away from the first organizing component 1 and the second organizing component 2; the dividing axis 3 includes a first dividing axis 31 and a second dividing axis 32, and the first dividing axis 31 and the second dividing axis 32 are respectively provided with a first bevel tooth 10 and a second bevel tooth 20, and the first bevel tooth 10 and the second bevel tooth 20 can rotate around the axis of the first bevel tooth 10 and the second bevel tooth 20 respectively.

[0029] The "flower basket" mentioned below refers to a slice flower basket 7 for carrying a plurality of slices.

[0030] As mentioned above, Figure 1 and Figure 5 As shown, the sliced ​​silicon wafer sorting mechanism provided by the present application includes a first sorting component 1 and a second sorting component 2 which are arranged at intervals, and a spacing axis 3 which is arranged between the first sorting component 1 and the second sorting component 2 and can be close to or away from the first sorting component 1 and the second sorting component 2. When the sorting mechanism is used to sort multiple sliced ​​silicon wafers 100 in the flower basket, the spacing axis 3 can be inserted between two sliced ​​silicon wafers 100, and the first sorting component 1 and the second sorting component 2 are respectively on the sides of the two columns of silicon wafers, and the middle spacing axis 3 can be moved toward the first sorting component 1 and the second sorting component 2 at the same time, so that the entire column of sliced ​​silicon wafers 100 between the first sorting component 1 and the spacing axis 3 and the entire column of sliced ​​silicon wafers 100 between the second sorting component 2 and the spacing axis 3 are sorted at the same time, and the two slices are separated according to a preset spacing, which solves the problem that the prior art cannot solve the problem of being unable to sort and sort due to the small spacing between the slices, and brings convenience to the sorting of the sliced ​​silicon wafers 100.

[0031] Specifically, the above-mentioned dividing shaft 3 includes a first dividing shaft 31 and a second dividing shaft 32, and the first bevel gear 10 and the second bevel gear 20 on the first dividing shaft 31 and the second dividing shaft 32 can rotate around their own axes; in addition, the first dividing shaft 31 and the second dividing shaft 32 also include a pad 4, which is configured to contact the side of the sliced ​​silicon wafer 100. The first bevel gear 10 and the second bevel gear 20 are screwed to the first dividing shaft 31 and the second dividing shaft 32.

[0032] like Figure 1 and Figure 2 As shown, taking a flower basket containing two rows of sliced ​​silicon wafers 100 as an example, when in use, the spacing axis 3 is slowly inserted into the gap between the two slices according to the positional relationship that the first spacing axis 31 is at the bottom and the second spacing axis 32 is at the top, and the first sorting component 1 and the second sorting component 2 are respectively lowered to the sides of the two rows of slices; then, the first spacing axis 31 and the second spacing axis 32 are controlled to rotate clockwise (or counterclockwise) so that the first bevel gear 10 and the second bevel gear 20 are respectively inserted into the gaps between the two adjacent rows of slices on both sides, and then the first spacing axis 31 is controlled to move in the direction indicated by the first bevel gear 10, and the second spacing axis 32 is controlled to move in the direction indicated by the second bevel gear 20, so that the first row of slices and the second row of slices in the flower basket are away from each other by a preset spacing, that is, the spacing effect is achieved.

[0033] Among them, when the aforementioned first dividing axis 31 and the second dividing axis 32 move toward the first column of slices and the second column of slices respectively, the first sorting component 1 on the other side of the first column of slices is controlled to move toward the first column of slices, and the second sorting component 2 is controlled to move toward the second column of slices, that is, the slices are pushed from both sides of the two columns of slices to finally achieve the purpose of sorting.

[0034] In addition, considering that the spacing between the two columns of slices in the flower basket is inconsistent, it is inconvenient to insert the slices into the gap between the two columns. In some embodiments, the diameter of the first spacing axis 31 is set to be smaller than the diameter of the second spacing axis. When the first spacing axis 31 enters the gap between the two columns of slices, the smaller diameter enters first, and after separating the two columns of slices by a certain distance, the second spacing axis 32 with a larger diameter continues to push the two columns of slices to both sides, thereby achieving the purpose of separation.

[0035] In some embodiments, the aforementioned first organizing component 1 and the second organizing component 2 have the same structure and can both include upper and lower limit teeth 5 and baffles 6, and the bottom surface of the tooth groove of the limit teeth 5 is coplanar with the first surface of the baffle 6 in the vertical direction.

[0036] like Figure 3As shown, the limiting teeth 5 and the baffle 6 of the first and second sorting components 1 and 2 are aligned in the vertical direction, and the limiting teeth 5 match the number of slices in the basket, so that there is a limiting tooth 5 between adjacent sliced ​​silicon wafers 100. When it moves close to the side of the sliced ​​silicon wafer 100, the limiting teeth 5 first separate all the sliced ​​silicon wafers 100, and continue to move until the side of the slice contacts the baffle 6 at the bottom, and then cooperate with the separation axis 3 to move a preset distance to realize the sorting of all the slices. The function of the baffle 6 is to insulate and prevent the side of the slice from being worn during sorting. Therefore, the baffle 6 needs to be made of a soft material with insulating properties, such as PEEK.

[0037] Of course, the aforementioned first sorting component 1, second sorting component 2 and dividing shaft 3 all include component devices that drive their movement, wherein a first driving component is provided to simultaneously control the first sorting component 1 and the second sorting component 2 to increase the uniformity of the sorting actions of the first sorting component 1 and the second sorting component 2; the second driving component independently controls the rotation and translation of the dividing shaft 3, and may utilize a motor and a high-precision cylinder, and this embodiment does not make any specific limitation on this.

[0038] In some embodiments, Figure 4 As shown, the area where the pad 4 is used to contact the slicing silicon wafer 100 includes a transition surface and a first plane, and the extension surface of the first plane is higher than the bottom surface of the tooth groove of the first bevel tooth 10 or the second bevel tooth 20. The transition surface can be an arc, or a straight slope formed by chamfering. During the rotation of the separation shaft 3, the transition surface can reduce the friction or impact on the side of the slicing silicon wafer 100. In addition, the first plane is parallel to the groove surface of the limit tooth 5, and the height of the surface in the vertical direction can be set slightly higher than the height of the plane where the tooth groove of the first bevel tooth 10 or the second bevel tooth 20 is located, so that the pad 4 contacts the edge of the slicing before the tooth groove of the first bevel tooth 10 or the second bevel tooth 20, protecting the slicing silicon wafer 100 from wear.

[0039] In the second aspect, the utility model provides a wafer inversion device, comprising two wafer arranging mechanisms as any of the aforementioned ones, and also comprising a wafer basket 7 arranged directly below the wafer arranging mechanism, a basket top tooth assembly 8 that can be inserted into the wafer basket 7, and a basket positioning platform; the wafer basket 7 is arranged on the basket positioning platform, and the basket top tooth assembly 8 is used to push out the silicon wafers in the wafer basket 7 or extend the wafer basket 7 to receive the silicon wafers; the wafer arranging mechanism is configured to arrange the wafers 100 to be inserted into the wafer basket 7 above the wafer basket 7, or to arrange the wafers 100 taken out of the wafer basket 7.

[0040] The wafer flipping device provided by the utility model is provided with a wafer basket 7 for carrying the wafer slices 100, a wafer basket positioning platform for placing the wafer basket 7, and a wafer basket top tooth assembly 8 which can be inserted into the wafer basket 7 on the basis of the aforementioned wafer arranging mechanism. The wafer flipping device provided by the utility model can, by using the wafer basket top tooth assembly 8, deliver the wafer slices 100 in the wafer basket 7 out of the wafer basket 7, and guide the external wafer slices 100 to be inserted into the wafer basket 7, so as to realize the wafer flipping action. The wafer flipping device of the utility model can take out all the wafer slices 100 in the wafer basket 7 at one time, or insert all the wafer slices 100 into the wafer basket 7 at one time, thereby improving the efficiency of inserting and taking out the wafer slices 100.

[0041] In some embodiments, the film rewinding device may further include a boat turning mechanism 9, such as Figure 6 and Figure 7 As shown, the boat turning mechanism 9 is arranged on the left side of the wafer basket 7. A wafer boat (a device for carrying silicon wafers) is fixed in the mechanism. The structure of the wafer boat is similar to that of the wafer basket 7. Because of the way of inserting silicon wafers in the wafer boat, the wafer boat needs to be turned from the wafer boat to the wafer boat when inserting the silicon wafers in the wafer boat. Figure 6 The position shown is rotated 90° clockwise so that the front of the wafer boat faces upward, so as to facilitate the insertion and removal of silicon wafers from the front of the wafer boat. When placing silicon wafers into the slice basket 7, it is necessary to align each slice directly above the basket; during aligning, the first aligning component 1 and the second aligning component 2 cooperate with the spacing axis 3 to complete the aligning of all sliced ​​silicon wafers 100. The top tooth component 8 of the basket includes top teeth and a drive to control the top teeth to move up and down, and a sliding component to control the top teeth to move left and right, so as to be compatible with slice baskets 7 at different positions.

[0042] In some embodiments, the aforementioned wafer flipping device further includes a mechanical gripper, which is movably disposed above the slicing basket 7 and is used to insert the slicing silicon wafer 100 into the slicing basket 7 or grab the slicing silicon wafer 100 from the slicing basket 7. The mechanical gripper is used to adsorb and fix each slicing silicon wafer 100, and complete the import and export of the slicing silicon wafer 100 in the basket, or to realize the import and export of the silicon wafer between the basket and the wafer boat. The design of the suction cup for adsorbing the silicon wafer on the mechanical hand is related to the number and parameters of the slicing silicon wafer 100, and this embodiment does not impose specific restrictions on this.

[0043] Specifically, Figure 7 As shown, the boat turning mechanism 9 in the aforementioned embodiment may include a bottom plate, a side plate and a rotating shaft rotatably connected to the side plate, and the side plate is provided with a sheet limiting groove, and the sheet limiting groove is arranged one-to-one correspondingly with the card slot in the sheet flower basket 7. Figure 7 The arrow in the figure indicates the steering angle of the connecting shaft.

[0044] Finally, the utility model provides a slice tidying mechanism and a film reversing device, the slice tidying mechanism includes a first tidying component 1 and a second tidying component 2 arranged at intervals, and a spacing axis 3 arranged between the first tidying component 1 and the second tidying component 2 and can be close to or away from the first tidying component 1 and the second tidying component 2; the spacing axis 3 includes a first spacing axis 31 and a second spacing axis 32, and the first bevel teeth 10 and the second bevel teeth 20 on the first spacing axis 31 and the second spacing axis 32 can rotate around their axis. The slice tidying mechanism provided by the utility model solves the problem that the prior art cannot solve the problem of being unable to separate and tidy up due to the small spacing between the slices, which brings convenience to the tidying up of the sliced ​​silicon wafers 100. In addition, the film reversing device provided can export or insert all the sliced ​​silicon wafers 100 at one time, which improves the efficiency of inserting and taking out the sliced ​​silicon wafers 100.

[0045] It should also be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
