[0002] Thin-wafer processing technology is involved in high-precision fields such as consumer electronics, automobile manufacturing, and solar photovoltaics. Specifically, the thin wafers are silicon wafers. During processing, the cut silicon wafers are rectangular and relatively thin. Impurities such as particles, organic impurities, inorganic impurities, metal ions, silicon powder, dust, etc. will remain on the cut surface. After grinding, it is easy to cause the silicon wafers to become mottled, blue, black, etc., resulting in unqualified silicon wafers.
[0003] Since the wafers flowing out of the sorting machine are stacked together into thin layers of rectangular silicon wafers, to improve the pass rate, the wafer stacks need to be broken up and then aligned. Impurities are removed during the alignment process, and the wafer stacks are aligned before further processing. Currently, this alignment process is mainly performed manually, which has a low accuracy rate, wastes a lot of manpower, and increases production costs. Utility Model Content
[0004] The purpose of the utility model is to provide an air blowing aligning device, which aims to solve the problem of low accuracy of sheet stacking formed by manually aligning multiple sheets stacked together, and can reduce manpower and thus reduce production costs.
[0005] The utility model discloses an air blowing and aligning device, which is used for aligning a sheet stack formed by stacking multiple sheets together, comprising a support structure, a carrier fixedly mounted on the support structure, a pair of pushing structures arranged opposite to each other along the circumference of the carrier, and a sliding drive mechanism for driving the two opposing pushing structures to slide back and forth in a direction toward or away from each other in the direction of the carrier, and further comprising an air blowing structure and an extrusion structure, wherein:
[0006] The blowing structure is installed at the side of the carrier. The blowing structure separates adjacent sheets by gas, while the pushing structure squeezes and aligns the sheet stack. The squeezing structure is used to press the top of the sheet stack.
[0007] As an improvement, the air blowing structure corresponds one-to-one to the pushing structure, and the air blowing structures are respectively arranged on one side of the carrier located at the pushing structure, or the air blowing structures are respectively arranged one-to-one on the pushing structure.
[0008] As an improvement, the pushing structure includes a vertical plate structure slidably arranged on the supporting structure, and a pushing block extending toward the carrier is installed on the vertical plate structure.
[0009] As an improvement, two push blocks are provided on the vertical plate structure and are spaced apart along the extending direction of the side edges of the sheet stack.
[0010] As an improvement, the blowing structure includes a blowing nozzle, and the blowing direction of the blowing nozzle is set to form a preset angle with the extending direction of the sheet stack.
[0011] As an improvement, the blowing structure is fixedly arranged on the pushing structure, and two blowing nozzles are arranged at intervals along the side extension direction of the sheet stack.
[0012] As an improvement, the sliding drive mechanism includes a first sliding drive mechanism and a second sliding drive mechanism, the first sliding drive mechanism and the second sliding drive mechanism are respectively fixed on the support structure, and the first sliding drive mechanism and the second sliding drive mechanism respectively drive the two relative pushing structures to approach or move away from each other toward the direction of the carrier.
[0013] As an improvement, the support structure includes a first support plate and a second support plate, the first support plate and the second support plate are vertically fixed, the first sliding drive mechanism is fixed on the first support plate, and the second sliding drive mechanism is fixed on the second support plate.

[0017] During operation, the thin sheet stacks flowing out of the sorting machine are transported to the carrier, and the sliding drive mechanism drives the pushing structures arranged in pairs on the circumference of the carrier to slide toward each other in the direction of the carrier until the pushing structures slide to the side of the thin sheet stack. The blowing structure blows air toward the side of the thin sheet stack to separate adjacent thin sheets and blow away impurities on the thin sheets.

[0024] It should be noted that the thickness of the thin slice is no more than 1 cm. In this embodiment, the thin slice is a silicon wafer.
[0025] like Figure 1 and Figure 2 As shown, the blowing and aligning device of the present invention is used to align a thin film stack 70 formed by stacking multiple rectangular silicon wafers together, including a support structure 10, a carrier 20 fixedly installed on the support structure 10, a pushing structure 30 arranged opposite to each other along the circumference of the carrier 20, and a sliding drive mechanism 40 for driving the two opposite pushing structures 30 to slide back and forth in the direction of the carrier 20 towards or away from each other, and also includes a blowing structure 50 and an extrusion structure 60, wherein the blowing structure 50 is installed at the side of the carrier 20, and the blowing structure 50 separates adjacent silicon wafers through gas while the pushing structure 30 extrude and align the thin film stack 70, and the extrusion structure 60 is used to press the top of the thin film stack 70.
[0026] During operation, the thin wafer stack 70 flowing out of the sorting machine is transported to the carrier 20. Specifically, it can be transported manually or by a robot. The sliding drive mechanism 40 drives the pushing structures 30 arranged in pairs on the circumference of the carrier 20 to slide toward each other in the direction of the carrier 20 until the pushing structures 30 slide to the side of the thin wafer stack 70. The blowing structure 50 blows air toward the side of the thin wafer stack 70 to separate the adjacent silicon wafers by blowing and blow away the impurities on the silicon wafers. The sliding drive mechanism 40 drives the pushing structures 30 arranged in pairs on the side of the thin wafer stack 70 to squeeze the side of the thin wafer stack 70, which can align the thin wafer stack 70. The squeezing structure 60 then presses the top of the thin wafer stack 70 to discharge the gas between the adjacent silicon wafers and compact the thin wafer stack 70. The blowing aligning device of the present invention solves the problem of low accuracy of manually aligning the thin wafer stack 70 formed by stacking multiple rectangular silicon wafers together. Replacing manual aligning with the blowing aligning device can reduce manpower and thus reduce production costs.
[0027] In the present invention, since the silicon wafer is rectangular, four groups of pushing structures 30 are provided, and two groups of pushing structures 30 are correspondingly provided on opposite sides of the carrier 20 .
[0028] Specifically, the sliding drive mechanism 40 includes a first sliding drive mechanism arranged between two groups of pushing structures 30 on one opposite side of the platform 20, and a second sliding drive mechanism arranged between two groups of pushing structures 30 on the other opposite side of the platform 20. The first sliding drive mechanism and the second sliding drive mechanism respectively drive the corresponding two groups of pushing structures 30 to slide synchronously toward or away from each other in the direction of the platform 20.
[0029] Typically, the first sliding drive mechanism and the corresponding two groups of pushing structures 30 , and the second sliding drive mechanism and the corresponding two groups of pushing structures 30 are driven by pulleys and belts.
[0030] In some other embodiments, a sliding drive mechanism 40 may be provided at each group of pushing structures 30 , and the four groups of pushing structures 30 are driven by four groups of sliding drive mechanisms 40 . Typically, the sliding drive mechanism 40 is an electric cylinder or a rack and pinion drive mechanism.
[0031] In the present invention, the blowing structures 50 correspond to the pushing structures 30 in a one-to-one manner, and the blowing structures 50 are respectively arranged on the pushing structures 30 in a one-to-one manner.
[0032] Specifically, the blowing structure 50 includes a blowing nozzle, the blowing direction of which is set to a preset angle with respect to the extension direction of the sheet stack 70 . In order to improve the separation effect, two blowing nozzles are spaced apart along the side extension direction of the sheet stack 70 .
[0033] Typically, the blowing direction is perpendicular to the extending direction of the sheet stack 70, and the preset angle is 90 degrees; of course, it can also be set to other angles, especially when two blowing nozzles are provided, and the blowing directions of the two blowing nozzles are set far apart.
[0034] In some other embodiments, the four groups of blowing structures 50 can also be fixed on the sides of the carrier 20 corresponding to the four groups of pushing structures 30 respectively. The blowing structure 50 and the pushing structure 30 are separate structures and do not move with the pushing structure 30.
[0035] Of course, a group of air blowing structures 50 can also be provided, as long as adjacent silicon wafers can be separated. The number and arrangement of the air blowing structures 50 are set according to actual needs.
[0036] In the present invention, the extrusion structure 60 includes an extrusion support 61, an elevating drive mechanism 62 fixedly mounted on the extrusion support 61, and a translation drive mechanism 63 fixedly mounted on the output portion of the elevating drive mechanism 62. A pressing plate 64 is fixedly mounted on the output portion of the translation drive mechanism 63. After the four sets of pushing structures 30 have aligned the wafer stack 70, the translation drive mechanism 63 drives the pressing plate 64 to move above the wafer stack 70. The elevating drive mechanism 62 then drives the translation drive mechanism 63 and the pressing plate 64 downward to press the top of the wafer stack 70, expelling the gas between adjacent silicon wafers and thereby compacting the wafer stack 70.
[0037] Of course, the extrusion structure 60 can also be set as the following structure, which includes an extrusion bracket 61, a horizontal extension arm fixedly installed on the extrusion bracket 61 and extending to the top of the platform 20, and a lifting drive mechanism 62 arranged above the platform 20 and fixedly installed on the horizontal extension arm, and a pressure plate 64 is fixedly installed on the output part of the lifting drive mechanism 62.
[0038] Specifically, the lifting drive mechanism 62 and the translation drive mechanism 63 are electric cylinders; of course, they can also be screw-nut assemblies driven by motors.
[0039] In the present invention, the support structure 10 includes two layers of support plates arranged at vertical intervals, and the platform 20 is fixedly installed above the upper support plate. A gap is provided between the platform 20 and the upper support plate. The first sliding drive mechanism and the second sliding drive mechanism are respectively installed on the two layers of support plates, which is convenient for installing the first sliding drive mechanism and the second sliding drive mechanism, and can avoid interference between the first sliding drive mechanism and the second sliding drive mechanism.
[0040] like Figure 1 As shown, the two layers of support plates are a first support plate 11 located at the lower layer and a second support plate 12 located at the upper layer. The platform 20 is fixedly installed above the second support plate 12. Support columns or support strips are respectively provided between the first support plate 11 and the second support plate 12, and between the platform 20 and the second support plate 12 for support.
[0041] Specifically, the first sliding drive mechanism and the second sliding drive mechanism respectively drive the first pulley 41 and the second pulley 42 installed on the support plate on the opposite sides of the platform 20, the transmission belt 43 arranged around the first pulley 41 and the second pulley 42, and the rotation drive mechanism connected to the first pulley 41 or the second pulley 42. Usually, the rotation drive mechanism is a motor; the two sets of propulsion structures 30 located on the opposite sides of the platform 20 are respectively fixedly connected to the transmission belt 43 on both sides of the first pulley 41 and the second pulley 42. When the first pulley 41, the second pulley 42 and the transmission belt 43 rotate in the forward direction, they can drive the two sets of propulsion structures 30 to slide in opposite directions, that is, the two sets of propulsion structures 30 slide in the direction closer to the platform 20; when the first pulley 41, the second pulley 42 and the transmission belt 43 rotate in the reverse direction, they can drive the two sets of propulsion structures 30 to slide in the opposite direction, that is, slide in the direction away from the platform 20.
[0042] Typically, the extrusion bracket 61 of the extrusion structure 60 is fixedly connected to the first support plate 11 of the support structure 10 .
[0043] The sliding drive mechanism 40 of this embodiment can also be set to the following structure, including a transmission gear rotatably installed on the support plate, a first rack and a second rack arranged on opposite sides of the transmission gear, and two groups of pushing structures 30 located on opposite sides of the carrier 20 are fixedly connected to the first rack and the second rack respectively, and the two groups of pushing structures 30 can also be realized to slide synchronously toward or away from each other in the direction of the carrier 20.
[0044] In the present invention, the pushing structure 30 includes a vertical plate structure slidably mounted on the supporting structure 10 , and a pushing block 35 extending toward the carrier 20 is mounted on the vertical plate structure.
[0045] In order to improve the neatness, the push block 35 is a vertically arranged strip block, usually made of soft materials such as rubber and plastic, to avoid damaging the side edges of the sheet stack 70.
[0046] Typically, the vertical plate structure is provided with two push blocks 35 spaced apart along the side extension direction of the sheet stack 70 , which can form two contact locations and further improve the neatness effect.
[0047] like Figure 1 and Figure 2As shown, the vertical plate structure includes a base plate 31 and two vertical plates 32 spaced apart on the base plate 31 along the side extending from the wafer stack 70. An adapter plate 33 is fixed to the side of each vertical plate 32 near the carrier 20. A mounting plate 34 is fixed to each adapter plate 33. Two push blocks 35 are fixed to the mounting plates 34 on the corresponding sides. During use, the spacing between the two push blocks 35 can be adjusted to accommodate silicon wafers of different sizes by replacing adapter plates 33 with different lengths or by providing mounting holes in different locations on the adapter plates 33.
[0048] In order to facilitate the sliding of the pushing structure 30, two sets of parallel slide rail slider mechanisms are respectively provided on the first support plate 11 and the second support plate 12. The bottom plate 31 is fixedly connected to the sliders of the two sets of slide rail slider mechanisms, which can make the sliding of the pushing structure 30 more stable.
[0049] In the present invention, in order to facilitate the blowing structure to separate adjacent silicon wafers through gas, a blowing structure 50 is respectively provided on the adjacent side or the distal side of the two push blocks 35. Usually, when the distance between the two push blocks 35 is small, the two groups of blowing structures 50 are arranged on the outer sides of the two push blocks 35. When the distance between the two push blocks 35 is large, the two groups of blowing structures 50 are arranged on the inner sides of the two push blocks 35.
[0050] The above descriptions are merely some embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
