DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.
[0033] Example 1
[0034] See also Figure 1-4 , the invention provides a technical solution for the edge skin clamping mechanism:
[0035] It comprises two groups of edge skin clamping mechanisms 1 which are symmetrically spaced apart from each other, a spacing control mechanism for controlling the two groups of edge skin clamping mechanisms 1 to move closer to or farther away from each other, and a conveying device for transferring waste materials.
[0036] The conveying device includes an X-axis guide rail 2, two sets of side skin clamping mechanisms 1 are respectively slidably installed on the X-axis guide rail 2, an X-axis moving slide 3 is also slidably installed on the X-axis guide rail 2, an X-axis moving cylinder 4 is horizontally installed at the end of the X-axis guide rail 2, and the telescopic end of the X-axis moving cylinder 4 is connected to the X-axis moving slide 3, which is used to control the transfer movement of the two sets of side skin clamping mechanisms 1 in the X-axis direction. The conveying device includes a Y-axis telescopic slide 24 arranged on the left and right sides of the back of the X-axis guide rail 2 for driving the X-axis guide rail 2 to move forward and backward; the conveying device also includes a Z-axis lifting component for driving the Y-axis telescopic slide 24 to move up and down When working, the edge skin workpiece can be automatically clamped and placed by controlling the spacing control mechanism. In addition, an X-axis moving cylinder 4 is horizontally installed at the end of the X-axis guide rail 2, and the telescopic end of the X-axis moving cylinder 4 is connected to the X-axis moving slide 3. The skin clamping mechanism 1 can be controlled to move left and right on the X-axis guide rail 2 by driving the X-axis moving cylinder 4. In conjunction with the aforementioned Z-axis lifting assembly and Y-axis telescopic slide, the cut edge skin workpiece can be automatically transferred to the collecting barrel. By setting the edge skin clamping mechanism of the present invention, the automatic turnover of the edge skin material formed by cutting the single crystal silicon rod workpiece can be realized, thereby improving the processing efficiency.
[0037] The spacing control mechanism includes a spacing control motor 5, which is fixedly mounted on the X-axis moving slide 3. The output end of the spacing control motor 5 is connected to a double-headed screw 6. The axial ends of the double-headed screw 6 have opposite thread rotation directions and are respectively screwed with a spacing control nut seat 7. The two spacing control nut seats 7 are fixedly mounted on two sets of side skin clamping mechanisms 1. When the spacing control motor 5 starts to rotate, it directly drives the double-headed screw 6 to rotate. Since the axial ends of the double-headed screw 6 have opposite thread rotation directions, the two sets of spacing control nut seats 7 on the double-headed screw 6 will move towards each other or away from each other, thereby realizing the clamping, fixing and loosening and releasing actions of the side skin workpiece.
[0038] Figure 1 Combination Figure 5 As shown, the Z-axis lifting assembly includes a Z-axis slide rail slider assembly 8 for installing the Y-axis telescopic slide 24, the Z-axis slide rail slider assembly 8 is fixed on both sides of the middle frame, the Y-axis telescopic slides 24 on both sides are respectively fixed on the sliders of the Z-axis slide rail slider assembly 8, the sliders can translate up and down on the slide rails, and also includes a Z-axis lifting motor 9 relatively fixedly installed on the external frame, the Z-axis lifting motor 9 is connected to the Z-axis lifting screw 11 through the reducer 10, the Z-axis lifting screw 11 is threaded with a Z-axis nut seat 12, the Z-axis nut seat 12 and the Y-axis telescopic slide 24 are relatively fixedly installed, when working, the Z-axis lifting motor 9 is started to rotate, and after the speed reduction transmission by the reducer 10, the Z-axis lifting screw 11 is driven, and the Z-axis nut seat 12 is driven to move up and down, that is, the Y-axis telescopic slide 24 is driven to move up and down.
[0039] like Figure 2-4As shown, the edge skin clamping mechanism 1 includes a clamping and mounting outer frame 13, and an X-axis clamping slide 23 slidably mounted with the X-axis guide rail 2 is arranged on the back of the clamping and mounting outer frame 13. The X-axis clamping slide 23 is mounted on the X-axis guide rail 2 through a slider, and a discharge cylinder 14 is installed above the inner cavity of the clamping and mounting outer frame 13. The discharge cylinder 14 is installed upside down and upright, and a discharge push plate 15 is arranged at its bottom telescopic end. When the discharge cylinder 14 is extended, the workpiece is pushed off, and a clamping cylinder 16 is installed on the side wall of the clamping and mounting outer frame 13. The telescopic end of the clamping cylinder 16 is laterally extended into the clamping and mounting outer frame 13 and is connected with a clamping push plate 17. When the clamping cylinder 16 is extended, the clamping push plate 17 is driven to move closer to the inner wall of the other side of the clamping and mounting outer frame 13, thereby clamping and fixing the edge skin workpiece;
[0040] Furthermore, two groups of clamping limit slides 18 are vertically penetrated through the side walls of the clamping installation outer frame 13, and the inner ends of the clamping limit slides 18 are connected to the clamping push plate 17. The two groups of clamping limit slides 18 are arranged on both sides of the clamping cylinder 16, and serve as limit structures for the action of the clamping push plate 17, ensuring that the clamping push plate 17 moves horizontally along a straight line; two groups of unloading limit slides 25 are vertically penetrated through the inner wall of the clamping installation outer frame 13, and the bottom ends of the unloading limit slides 25 are connected to the unloading push plate 15. The two groups of unloading limit slides 25 are arranged on both sides of the unloading cylinder 14, and serve as limit structures for the action of the unloading push plate 15, ensuring that the unloading push plate 15 moves up and down along a straight line.
[0041] Furthermore, a V-shaped clamping plate 20 is movably installed on the inner side of the clamping push plate 17 through the clamping pin 19. The V-shaped clamping plate 20 can rotate around the clamping pin 19 and has a certain rotational activity space. As an adaptive clamping structure, when the middle position of the arc side wall of the edge skin workpiece and the middle position of the V-shaped clamping plate 20 have a certain front-to-back deviation, as the clamping push plate 17 is clamped and contacts the arc side wall of the edge skin workpiece, one side wall of the V-shaped clamping plate 20 touches the edge skin workpiece first, thereby utilizing the reaction force of the edge skin workpiece to make It itself produces a certain swing, so that after further clamping, the two side walls of the V-shaped clamp 20 can contact the outer wall of the edge skin workpiece to achieve stable clamping. Reset springs 21 are arranged between the back of the contact surfaces on both sides of the V-shaped clamp 20 and the clamping push plate 17. If the V-shaped clamp 20 produces a certain swing movement during the clamping process, the reset spring 21 on one side will be compressed at the same time. When the edge skin workpiece is released, the restoring elastic force of the reset spring 21 can be used to straighten and reset the V-shaped clamp 20.
[0042] Furthermore, both inner walls of the V-shaped clamp 20 and the bottom of the unloading push plate 15 are respectively provided with polyurethane soft contact blocks 22, and the inner wall of the contact side of the clamping and mounting outer frame 13 is provided with a contact plate 26, which can preferably be made of soft polyurethane to protect the workpiece.

[0044] See also Figure 5 The invention provides a technical solution for the edge skin ejection mechanism:
[0045] It includes a side skin ejection mechanism 30 for ejecting the cut side skin and a lifting drive mechanism 40 for driving the side skin ejection mechanism 30 to move up and down. The side skin ejection mechanism 30 is provided with two groups symmetrically distributed on the left and right. The side skin ejection mechanism 30 includes a transverse ejection rod and a driving cylinder for driving the transverse ejection rod.
[0046] The lifting drive mechanism 40 includes a lifting drive motor and a lifting drive screw rod vertically mounted on the frame, and slide rails and sliders are arranged on both sides of the lifting drive screw rod, and lifting mounting seats are installed on the sliders on both sides. The rear of the lifting mounting seat is connected to the lifting drive screw rod through a lifting nut seat, and a groove is provided in the center of the front side of the lifting mounting seat for accommodating the workpiece, and the side skin cutting mechanism 50 is respectively installed on the left and right side walls of the groove. In this embodiment, the side skin cutting mechanism 50 is a wire saw;
[0047] The lateral ejector rod and the driving cylinder are installed on the platform surfaces on both sides of the lifting mounting seat, corresponding to the two sets of edge skin clamping mechanisms 1.

[0059] Step 2.3: The edge skin cutting mechanism 50 continues to move downward to cut the edge skins on both sides of the crystalline silicon rod. While the edge skin cutting mechanism 50 cuts the crystalline silicon rod downward, the edge skin clamping mechanism also descends to a suitable position at the same time.
[0060] Step 2.4: The edge skin clamping mechanism 1 descends to a suitable position, and the unloading cylinder 14 in the edge skin clamping mechanism 1 extends to press the edge skin; the edge skin unloading cylinder 14 keeps pressing the edge skin, and the edge skin cutting mechanism 50 continues to cut the transparent silicon rod downward.

[0063] Step 4: The conveying mechanism drives the side skin to retract along the Y-axis telescopic slide 24; the X-axis moving cylinder 4 is started to drive the side skin clamping mechanism 1 to move along the X-axis guide rail 2 to the top of the side collection barrel; the distance between the two side skin clamping mechanisms is reduced to the minimum; the side skin clamping mechanism descends along the Z-axis lifting assembly, so that the lower end of the side skin of the crystalline silicon rod extends into the collection barrel, the clamping cylinder 16 in the skin clamping mechanism 1 is released, and the unloading cylinder 14 is pushed out to place the side skin of the crystalline silicon rod into the collection barrel.
[0064] Step 5: The edge skin clamping mechanism 1 moves upward, and the edge skin cutting mechanism 50 also moves upward synchronously after being appropriately expanded; the crystal rod is rotated 90° to prepare for squaring the other side.
[0065] Step 6: Clean the edge skin of the crystalline silicon rods in the aggregate bucket; specifically, the aggregate bucket is connected to the AGV car externally through a crawler conveyor mechanism. The AGV car comes regularly to take away the full aggregate bucket and return the empty aggregate bucket, thereby realizing automated operation.
