DETAILED DESCRIPTION

[0021] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0022] Embodiment 1: The embodiment of the present application provides an automatic docking device for a sorting machine, which includes a material receiving mechanism 100, a docking mechanism 200 and a docking conveying mechanism 300. The docking conveying mechanism 300 can realize the automatic conveyance of the material tray assembly between the material receiving mechanism 100 and the docking mechanism 200.

[0023] For details, see Figure 1The receiving mechanism 100 includes a first frame 110. A plurality of receiving assemblies 120 for placing a silicon wafer pile are fixedly mounted on the working table of the first frame 110. The plurality of receiving assemblies 120 are arranged equidistantly in sequence along the length direction of the working table of the first frame 110. Each receiving assembly 120 includes a base fixedly mounted on the working table of the first frame 110, a receiving rack arranged on the base, and a receiving bottom plate 420 placed in the receiving rack. When silicon wafers are placed in the receiving assembly 120, the silicon wafers are stacked in sequence on the receiving bottom plate 420, and the receiving rack can limit the silicon wafer pile in the horizontal direction to ensure the stability of the silicon wafer pile.

[0024] A material taking assembly 130 for grabbing and conveying a silicon wafer stack is also provided on the first frame 110. Figure 1 The material taking component 130 includes a slide rail 131 fixedly mounted on the work surface of the first frame 110. The slide rail 131 is mounted above the material receiving component 120, and the slide rail 131 extends along the length direction of the first frame 110. A moving seat 132 is slidably mounted on the slide rail 131. The moving seat 132 is driven by a driving device and slides along the slide rail 131. A first lifting driving device 133 is fixedly mounted on the moving seat 132. The first lifting driving device 133 is drivingly connected to a clamping claw 134, and can drive the clamping claw 134 to rise and fall in a vertical direction. When it is necessary to grab a pile of silicon materials, the driving device drives the moving seat 132 to move to the top of the corresponding material receiving component 120, and then the first lifting driving device 133 drives the clamping claw 134 to move downward, and the silicon wafer pile is grabbed together with the material receiving bottom plate 420. Then, the first lifting drive device 133 drives the clamping claw 134 to move upward, and the moving seat 132 slides along the slide rail 131, so that the silicon wafer stack can be transported to the next workstation.

[0025] The driving device can be a driving electric cylinder or other forms of driving parts. The first lifting driving device 133 can be a driving electric cylinder, a cylinder or a hydraulic cylinder.

[0026] In another embodiment, two rows of receiving components 120 are arranged on the working surface of the first frame 110. The two rows of receiving components 120 are respectively arranged on both sides of the width direction of the working surface of the first frame 110. One row of receiving components 120 is automatically picked up by the above-mentioned picking up component 130, and the other row of receiving components 120 is manually picked up by an operator.

[0027] See also Figure 2 and Figure 3The docking mechanism 200 includes a second rack. Two first racks 210 and two second racks 220 are fixedly installed in the second rack. The length directions of the first rack 210 and the second rack 220 are parallel to the length direction of the second rack. The two first racks 210 are located in the same horizontal plane and are arranged in sequence along the width direction of the second rack. The two second racks 220 are located in the same horizontal plane and are arranged in sequence along the width direction of the second rack. At the same time, any second rack 220 is located directly above the adjacent first rack 210. Any end of any second rack 220 in the length direction is located in the same vertical plane as the adjacent end of the adjacent first rack 210 in the length direction. The first rack 210 is used to place a tray assembly without a silicon wafer stack, that is, an empty tray assembly, and the second rack 220 is used to place a tray assembly with a silicon wafer stack, that is, a fully loaded tray assembly.

[0028] A driving wheel and a driven wheel are rotatably mounted on the inner side of the first material rack 210, and the driving wheel and the driven wheel are respectively located at the two ends of the length direction of the first material rack 210. A first conveying belt 211 is wound around the outer side of the driving wheel and the driven wheel. The driving wheel is driven by the driving motor to rotate, so that the first conveying belt 211 can be driven to move, and then the material tray assembly located in the first material rack 210 can be driven to move along the length direction of the first material rack 210. Similarly, a driving wheel and a driven wheel are also rotatably mounted on the inner side of the second material rack 220, and the driving wheel and the driven wheel are respectively located at the two ends of the length direction of the second material rack 220. A second conveying belt 221 is wound around the outer side of the driving wheel and the driven wheel. The driving wheel is driven by the driving motor to rotate, so that the second conveying belt 221 can be driven to move, and then the material tray assembly located in the second material rack 220 can be driven to move along the length direction of the second material rack 220.

[0029] The docking mechanism 200 also includes a first conveying assembly for conveying the tray assembly. Figure 3 The first conveying assembly includes a column 250 fixedly installed in the second frame, and the column 250 is located at one end of the first material rack 210 and the second material rack 220. A lifting seat 260 is slidably installed on the column 250, and the lifting seat 260 is driven by a third lifting drive device fixedly installed in the second frame and rises and falls along the column 250. A third material rack 230 is fixedly installed on the lifting seat 260. The length direction of the third material rack 230 is perpendicular to the length direction of the first material rack 210 and the second material rack 220. A third conveying belt 231 is arranged in the third material rack 230, and the installation form of the third conveying belt 231 is the same as the installation form of the first conveying belt 211 and the second conveying belt 221.

[0030] In addition, two sets of vertical conveying components 240 are also arranged in the third material rack 230. Figure 4 and Figure 5Each set of vertical conveying components 240 includes a mounting plate 241 fixedly mounted in the third material rack 230, a second lifting drive device 242 fixedly mounted on the mounting plate 241, and a fourth conveying belt 243 component drivingly connected to the second lifting drive device 242. The fourth conveying belt 243 component is located on the inner side of the third material rack 230, and the conveying direction of the fourth conveying belt 243 component is perpendicular to the length direction of the third material rack 230.

[0031] It can be understood that, in the initial state, the conveying surface of the fourth conveyor belt 243 is lower than the conveying surface of the third conveyor belt 231. In this way, when the third conveyor belt 231 drives the tray assembly thereon to move, the vertical conveying assembly 240 in the third material rack 230 will not hinder the movement of the tray assembly. When the third material rack 230 needs to receive the tray assembly on the first material rack 210 or the second material rack 220 or needs to transport the tray assembly on the third material rack 230 to the first material rack 210 or the second material rack 220, the fourth conveyor belt 243 assembly is driven to rise by the second lifting drive device 242, and the tray assembly located on the third conveyor belt 231 can be lifted and placed on the fourth conveyor belt 243, thereby changing the conveying direction of the tray assembly.

[0032] It should be noted that the fourth conveyor belts 243 in the two sets of vertical conveyor assemblies 240 are respectively aligned with the first conveyor belts 211 in the two first racks 210. This ensures the conveying stability of the tray assembly when it moves from the third rack 230 to the first rack 210 or the second rack 220.

[0033] See also Figure 6 Each material tray assembly includes a receiving base 410, which is roughly square. A plurality of limiting columns 430 arranged in the vertical direction are fixedly installed on the receiving base 410. These limiting columns 430 enclose a rectangular area, the center of which coincides with the center of the receiving base 410, and the side length of the rectangular area is equal to or slightly greater than the side length of the receiving bottom plate 420. When the receiving bottom plate 420 is placed on the receiving base 410, the inner side of each limiting column 430 is in contact with the side of the receiving bottom plate 420, thereby limiting the horizontal direction of the receiving bottom plate 420. A card slot 440 for the clamping claw 134 to extend into is provided in the middle of any two opposite sides of the receiving bottom plate 420, so that the clamping claw 134 can clamp the receiving bottom plate 420, thereby ensuring the stability of the clamping claw 134 when clamping the silicon wafer material pile.

[0034] It should be noted that the inner widths of the first rack 210, the second rack 220 and the third rack 230 are slightly larger than the side length of the receiving base 410. In this way, the translation stability of the tray assembly can be ensured when the tray assembly moves in the first rack 210, the second rack 220 or the third rack 230.

[0035] See also Figure 8 The docking conveying mechanism 300 includes a second conveying assembly 310 and a temporary storage rack 320 disposed on the first frame 110. The second conveying assembly 310 includes a mounting base 311 fixedly mounted on the first frame 110. The mounting base 311 is located at one end of all the receiving assemblies 120 and is arranged in the same straight line with all the receiving assemblies 120. Fig. 9 Two first positioning plates 312 arranged in the vertical direction are fixedly installed on both sides of the mounting base 311, and a driving wheel and a driven wheel are rotatably installed inside the two first positioning plates 312, and the driving wheel and the driven wheel are respectively located at the two ends of the length direction of the first positioning plates 312. A fifth conveying belt 313 is wound around the driving wheel and the driven wheel. When the tray assembly is located on the fifth conveying belt 313, the two first positioning plates 312 are respectively located on both sides of the tray assembly. The conveying direction of the fifth conveying belt 313 is parallel to the length direction of the third material rack 230, and when the lifting seat 260 drives the third material rack 230 to rise and fall to the same horizontal plane as the fifth conveying belt 313, the fifth conveying belt 313 docks with the third conveying belt 231 in the third material rack 230. In this way, the third conveying belt 231 can convey the tray assembly on the third material rack 230 to the fifth conveying belt 313, thereby conveying the tray assembly in the docking structure to the receiving mechanism 100. Similarly, the fifth conveyor belt 313 can convey the tray assembly thereon to the third conveyor belt 231, thereby conveying the tray assembly in the receiving mechanism 100 to the docking mechanism 200. Thus, the tray assembly is transported back and forth between the receiving mechanism 100 and the docking mechanism 200.

[0036] In addition, a fourth lifting drive device 314 is fixedly mounted on the mounting base 311, and the fourth lifting drive device 314 is drivingly connected to a lifting platform 315 located between the two first positioning plates 312. The lifting platform 315 can lift up the tray assembly located on the fifth conveyor belt 313 after being driven by the fourth lifting drive device 314, so as to facilitate placing the silicon wafer stack in the tray assembly.

[0037] Better, see Fig. 9 A boss 316 protruding upward is fixedly provided in the middle of the lifting platform 315. Correspondingly, a through hole 450 is provided in the middle of the receiving base 410 for the boss 316 to pass through. Figure 7When the tray assembly is on the fifth conveyor belt 313, the fourth lifting drive device 314 drives the lifting platform 315 to rise, and the boss 316 passes through the through hole 450 to first contact the material receiving bottom plate 420 and lift the material receiving bottom plate 420, and then the lifting platform 315 contacts the material receiving base 410 and lifts the material receiving base 410. Therefore, when the lifting platform 315 lifts the tray assembly from the fifth conveyor belt 313, the material receiving bottom plate 420 will be higher than the material receiving base 410.

[0038] It should be noted that when the clamping claw 134 clamps the receiving base plate 420 fully loaded with silicon wafers, the thickness of the portion of the clamping claw 134 extending to the lower end of the receiving base plate 420 is less than the height of the boss 316. In this way, when the clamping claw 134 places the silicon wafers together with the receiving base plate 420 in the receiving base 410, the receiving base plate 420 will be placed on the boss 316 first, and a gap will be formed between the receiving base plate 420 and the receiving base 410 for the clamping claw 134 to extend into, so that the clamping claw 134 can stably place the receiving base plate 420 together with the silicon wafers on the receiving base 410.

[0039] Preferably, a positioning assembly is also provided on the lifting platform 315. Fig. 9 The positioning assembly includes a second positioning plate 318 and a push plate 319 respectively arranged on opposite sides of the lifting platform 315. The push plate 319 is connected to the driving cylinder fixedly installed at the lower end of the lifting platform 315, and the moving direction of the push plate 319 driven by the driving cylinder is parallel to the conveying direction of the fourth conveyor belt 243. In addition, a limit cylinder is fixedly installed on any one of the first positioning plates 312. When the limit cylinder is in operation, it can drive the pressure plate to move through the piston rod to clamp the material receiving base 410 between the two first positioning plates 312.

[0040] See also Fig. 9 A sensor 317 for detecting whether there is a silicon wafer pile is also provided on the boss 316. The sensor 317 can be a weight sensor 317 or a sensor 317 in other forms.

[0041] The temporary storage rack 320 is fixedly mounted on the first frame 110 and is located on a side of the mounting base 311 away from the receiving assembly 120. The temporary storage rack 320 is arranged on the same straight line with the mounting base 311 and all the receiving assemblies 120. The temporary storage rack 320 is used to temporarily store the receiving bottom plate 420.

[0042] Preferably, a plurality of limiting posts 430 are fixedly installed on the upper end of the temporary storage rack 320, and the plurality of limiting posts 430 also enclose a rectangular area, and the side length of the rectangular area is equal to or slightly greater than the side length of the receiving bottom plate 420. When the receiving bottom plate 420 is placed on the temporary storage rack 320, the inner side of each limiting post 430 is in contact with the side of the receiving bottom plate 420, so as to limit the horizontal direction of the receiving bottom plate 420.
