[0002] After the silicon wafers are inspected and sorted by the sorting machine, they will be classified and stacked to form multiple groups of stacks with different inspection results. The stacks also need to be transported from the sorting machine to the re-inspection equipment for inspection.

The silicon wafers are stacked in the material boxes to form stacks. The material box conveying device conveys the material box to the re-inspection equipment for stacking inspection. The existing material box conveying device generally picks up the material box by clamping, magnetic adsorption or vacuum adsorption. The above-mentioned conveying methods have high requirements on the position of the material box and the movement accuracy of the material box conveying device. Therefore, in actual production, it is easy to fail to pick up or the material box falls off during the conveying process, affecting production efficiency. Utility Model Content

[0008] The material box handling device of the present application hooks the material box containing the stacked sheets through a hooking mechanism, and the hooking mechanism is driven by the first driving mechanism to realize the handling of the material box and the stacked sheets in the material box. Compared with the prior art method of picking up the material box and carrying it by clamping, magnetic adsorption or vacuum adsorption, there is no need for multiple alignment clamping or adsorption, and the movement accuracy is higher. The method of hooking and carrying the material box only needs to drive the hooking mechanism through the driving mechanism to drive the hooked material box to realize the handling of the stacked sheets between corresponding positions. The method of hooking and carrying the material box can effectively avoid the problem of picking failure or the material box falling off during transportation, and greatly improves the transportation and production efficiency.

[0009] Optionally, the material box includes a base and a carrying plate, the carrying plate is obliquely mounted on the base, the carrying plate is used to carry the laminated sheets, and positioning members are symmetrically provided on two opposite sides of the base;

[0011] The first driving mechanism is configured to drive the moving frame to move to drive at least one set of hooking components to move, so that at least two hook plates of each set of hooking components hook corresponding positioning pieces to drive the material box to move to the next process.

[0012] The positioning piece on the material box cooperates with at least two hook plates on the hooking mechanism to hook the material box to drive the laminated sheets in the material box to the next process, thereby completing the transportation process; positioning pieces are symmetrically arranged on two opposite sides of the base of the material box, and each set of hooking assemblies is equipped with at least two hook plates to hook the corresponding positioning pieces, which can not only keep the material box balanced and stable during transportation and improve the stability of material box transportation, but also because the material box is hooked on all sides, the force is evenly distributed and not easy to fall off, thereby ensuring the transportation and production efficiency of the laminated sheets.

[0013] Optionally, at least two hook plates are extended along the first direction and symmetrically installed on both sides of the mobile frame in parallel with each other, and one end of the hook plate extends along the second direction to form a hooking portion; the second direction is perpendicular to the first direction, and the hooking portion is configured to hook the corresponding positioning piece on the material box.

[0014] By cooperating with the positioning piece through the hooking portion formed on the hook plate, the weight of the material box itself can be utilized to hook up and hang the material box on the hooking portion, and since at least two hook plates are arranged parallel and symmetrically on the mounting movable frame, the stability of the hooking assembly in hooking the material box for transportation can be improved. The hooking portion and the hook plate are arranged perpendicularly, so that the hooking portion can hook up and drive the positioning piece while preventing the positioning piece from falling off from the hooking portion during the movement of the material box, that is, preventing the material box from falling off, thereby improving the transportation stability and efficiency.

[0015] Optionally, the positioning member includes a fixing seat, a connecting shaft and an anti-slip portion, and the fixing seat is arranged on the base of the material box;

The hooking portion is configured to hook the connecting shaft, and the anti-slip portion is configured to prevent the hooking portion from escaping from the connecting shaft.

[0017] The connecting shaft on the fixed seat cooperates with the hooking part, and the hooking part hooks the connecting shaft to hook and hold the entire material box. At the same time, the anti-slip part at one end of the connecting shaft can prevent the hooking part from escaping from the end of the connecting shaft, thereby improving the reliability of the hooking, thereby improving the stability and efficiency of the material box during the movement of the material box.

[0020] Optionally, the hooking mechanism further includes at least one set of pressing assemblies mounted on the movable frame, and each set of pressing assemblies is configured to press the laminates in the material box hooked by the corresponding hooking assembly onto the carrying plate.

[0021] The pressing assembly presses the stacked sheets in the material box held by the corresponding hooking assembly onto the carrying plate, ensuring that the stacked sheets will not fall off during the transportation of the material box, thereby further improving the reliability of transportation and improving the transportation efficiency.

[0023] The second driving member drives the pressure plate to rise and fall vertically and / or move horizontally, so that the pressure plate can be moved to the position corresponding to the stacking sheet in the material box, thereby pressing down the stacking sheet in the material box. At the same time, since the stacking sheet carried by the supporting plate is inclined, in order to ensure that the stacking sheet can be stably pressed, the pressure plate needs to be consistent with the inclination angle and direction of the supporting plate to ensure that the stacking sheet will not fall off during the transportation of the material box.

[0024] In a second aspect, the present application provides a sorting machine, comprising a detection and sorting mechanism, a plurality of material receiving components, and a material box handling device as described in any one of the first aspects, wherein:

[0026] Several receiving assemblies are located at the discharge station, each receiving assembly being configured to carry a material box and receive silicon wafers with the same test results after being inspected and sorted by the inspection and sorting mechanism through the material box, wherein the silicon wafers are stacked in the material box to form a stack;

[0027] The hooking mechanism is configured to hook a material box located at a discharge station and filled with laminated sheets;

[0028] The first driving mechanism is configured to drive the hooking mechanism to move, so as to drive the material box on the hooking mechanism to move to the next process.

[0029] The sorting machine of the present application carries a material box through a material receiving component and receives silicon wafers with the same detection results detected and classified by a detection and sorting mechanism through the material box, thereby transporting the stacked wafers through the material box, so that the material box conveying device can hook the material box through the hooking mechanism to realize the conveying of the stacked wafers, without the need to directly contact the stacked wafers output by the detection and sorting mechanism by clamping or adsorption.

[0032] The second position is far away from the discharge end of the detection and sorting mechanism, and the material box located at the second position is configured to be hooked by the hooking mechanism.

[0033] By driving at least two carriers on the material receiving component to move alternately by a second driving mechanism, the same material receiving component can alternately receive the inspected and classified silicon wafers output by the inspection and sorting mechanism, thereby improving the efficiency of the material box in receiving the stacked wafers. At the same time, the material receiving component alternately transports the material box containing the stacked wafers to a position away from the discharge end of the inspection and sorting mechanism for the hooking mechanism to hook and transport. The alternating feeding can effectively improve the handling efficiency of the material box handling device.

[0034] Optionally, the sorting machine also includes a stacking detection mechanism, which is located at the next process.

[0035] The stacking detection mechanism is used to perform corresponding inspections on the stacking wafers sorted by the sorting machine so that qualified stacking wafers can be packaged. The stacking detection mechanism will send out an empty material box. The material box conveying device can use the hooking mechanism to convey the empty material box sent out by the stacking detection mechanism back to the material receiving assembly at the discharging station, so that the material receiving assembly receives the silicon wafers with the same inspection results after inspection and classification by the inspection and sorting mechanism through the empty material box, thereby realizing the recycling and reuse of the material box and saving production costs. At the same time, the material box conveying device conveys the material box filled with stacking wafers to the stacking detection mechanism at the inspection and sorting mechanism. In the process of conveying the next stacking wafer from the stacking detection mechanism back to the inspection and sorting mechanism, the material box conveying device uses the return process to convey the empty material box, making full use of the conveying process of the material box conveying device.

[0039] By cooperating with multiple sets of detection and sorting mechanisms and material box handling devices, the material box handling device can continuously transport the material box containing stacked sheets at the discharge station to the stacking detection mechanism for inspection, thereby improving the overall production efficiency. The detection and sorting mechanisms are symmetrically arranged on both sides of the linear module. Under the drive of the linear module, the material box handling device can move to each detection and sorting mechanism to hook the material box containing stacked sheets, and can also receive the empty material box sent by the stacking detection mechanism and transport it to the discharge station of each detection and sorting mechanism. The detection and sorting mechanism and the stacking detection mechanism cooperate with the linear module to drive the movement stroke arrangement of the material box handling device, so that the end of the material box handling device only needs to move in the same direction to realize the handling process, which can effectively improve the handling efficiency and handling accuracy of the material box handling device, thereby improving the overall production efficiency.

[0054] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0055] As described in the background technology, several material boxes are set up at the discharge station of the sorting machine to receive silicon wafers with different test results respectively. The silicon wafers are stacked in the material box to form a stack. The material box handling device transports the material box to the re-inspection equipment for stacking inspection. The existing material box handling device generally picks up the material box by clamping, magnetic adsorption or vacuum adsorption. The above-mentioned several handling methods have high requirements on the position of the material box and the movement accuracy of the material box handling device. Therefore, in actual production, it is easy to fail to pick up or the material box falls off during the handling process, affecting production efficiency. Based on this, the present application proposes a material box handling device to solve the problem of how to avoid the problem of failure to pick up or the material box falling off during the handling process, thereby improving production efficiency.

[0056] See attached Figure 1 , Figure 1 FIG. 1 is a schematic structural diagram of a material box transport device according to an embodiment of the present application. Figure 1 As shown, in one or more embodiments, the material box handling device of the present application includes a first driving mechanism 10 and a hooking mechanism 20, and the driving end of the first driving mechanism 10 is connected to the hooking mechanism 20, wherein: the hooking mechanism 20 is configured to hook the material box 40 located at the discharge station M and equipped with the stacking sheet 30; the first driving mechanism 10 is configured to drive the hooking mechanism 20 to move, so as to drive the material box 40 on the hooking mechanism 20 to move to the next process.

[0057] The material box handling device of this embodiment hooks the material box 40 containing the stacking sheets 30 through the hooking mechanism 20, and the first driving mechanism 10 drives the hooking mechanism 20 to realize the handling of the material box 40 and the stacking sheets 30 in the material box 40. Compared with the prior art method of picking up the material box and then handling it by clamping, magnetic adsorption or vacuum adsorption, there is no need for multiple alignment clamping or adsorption, and the movement accuracy is higher. The method of hooking and handling the material box only needs to drive the hooking mechanism 20 through the driving mechanism to drive the hooked material box 40 to realize the handling of the stacking sheets 30 between corresponding positions. The method of hooking and handling the material box can effectively avoid the problem of picking failure or the material box 40 falling off during handling, thereby greatly improving the handling and production efficiency.

[0058] In one embodiment, see Figure 1-Figure 3 As shown, the material box 40 includes a base 41 and a carrying plate 42. The carrying plate 42 is obliquely mounted on the base 41. The carrying plate 42 is used to carry the laminate 30. Positioning members 43 are symmetrically provided on two opposite sides of the base 41.

[0059] The hooking mechanism 20 includes a mobile frame 21 and at least one set of hooking components 22. The at least one set of hooking components 22 is mounted on the mobile frame 21. The mobile frame 21 is mounted on the driving end of the first driving mechanism 10. The hooking component 22 includes at least two hook plates 221. The at least two hook plates 221 are symmetrically mounted on opposite sides of the mobile frame 21.

[0060] The first driving mechanism 10 is configured to drive the moving frame 21 to move to drive at least one set of hooking components 22 to move, so that at least two hook plates 221 of each set of hooking components 22 hook the corresponding positioning members 43 to drive the material box 40 to move to the next process.

[0061] The optional working process of the material box handling device of the embodiment of the present application is as follows: the first driving mechanism 10 can drive the mobile frame 21 to move in any direction and height. Based on this, the material box handling device can drive the mobile frame 21 to move through the first driving mechanism 10 to drive the hooking assembly 22 to the discharging station M. The same set of hooking assembly 22 can include two relatively installed hook plates 221 to cooperate with the positioning members 43 on the material box 40. For example, four positioning members 43 are symmetrically distributed on the material box 40. At the discharging station M, the two hook plates 221 correspondingly and synchronously hook the four positioning members 43, which can achieve a smooth hooking of the entire material box 40; after the hook plates 221 hook the positioning members 43, the first driving mechanism 10 drives the mobile frame 21 to rise, so that the hook plates 221 on the mobile frame 21 hook the material box 40, and the first driving mechanism 10 continues to drive the mobile frame 21 to move to the next process, thereby driving the material box 40 on the hook plate 221 to the process, thereby completing the material box handling at the discharging station M.

[0062] Specifically, the first drive mechanism 10 utilizes a six-axis robotic arm, the driving end of which is connected to the mobile frame 21, thereby driving the mobile frame 21 to move, thereby driving the hook assembly 22 on the mobile frame 21 to move. Furthermore, the first drive mechanism 10 also includes a horizontal drive module, on which the six-axis robotic arm can be mounted, and the horizontal drive module drives the six-axis robotic arm to move horizontally to the next process.

[0063] By cooperating with the positioning piece 43 on the material box 40 and at least two hook plates 221 on the hooking mechanism 20, the material box 40 is hooked to drive the laminated sheets 30 in the material box 40 to the next process, thereby realizing smooth transportation of the material box 40 between the discharge station M and the next process; positioning pieces 43 are symmetrically arranged on two opposite sides of the base 41 of the material box 40, and each set of hooking components 22 is equipped with at least two hook plates 221 to hook the corresponding positioning pieces 43, which can not only keep the material box 40 balanced and stable during the transportation process, but also improve the transportation stability of the material box 40. Since the material box 40 is hooked on all sides, the force is evenly distributed and it is not easy to fall off, thereby ensuring the transportation and production efficiency of the laminated sheets 30.

[0064] In one possible implementation, see Figure 1-Figure 3 As shown, at least two hook plates 221 are arranged along a first direction ( Figure 3 X direction) and are symmetrically mounted on both sides of the mobile frame 21 in parallel with each other. One end of the hook plate 221 extends in the second direction ( Figure 3 the second direction is perpendicular to the first direction, and the hooking portion 222 is configured to hook the corresponding positioning member 43 on the material box 40.

[0065] Specifically, at least two hook plates 221 are parallel to each other and vertically arranged on the mobile frame 21, and the hooking portion 222 is arranged perpendicular to the extension direction of the hook plate 221, so that the positioning member 43 can be hooked from the bottom of the positioning member 43. During the rising process of the hook plate 221, the positioning member 43 uses the weight of the material box 40 to hang on the hooking portion 222, thereby realizing the transportation of the entire material box 40. Optionally, in order to improve the stability of the hook and prevent the positioning member 43 from escaping from the hooking portion 222, the hooking portion 222 can be provided with a groove, and the positioning member 43 is hung in the groove. During the transportation process, the positioning member 43 is stably connected in the groove, which effectively improves the transportation stability, prevents the lamination 30 from shifting, and improves production efficiency. It should be understood that the hooking portion 222 can also be other hook structures that can cooperate with the positioning member 43 to hook the material box 40. Figure 1-Figure 3 It is only a schematic structure and is not intended to limit its specific structure.

[0066] By cooperating with the hooking portion 222 formed on the hook plate 221 and the positioning member 43, the weight of the material box 40 itself can be used to hook up and hang the material box 40 on the hooking portion 222. Since at least two hook plates 221 are arranged parallel and symmetrically on the mounting movable frame 21, the stability of the hooking assembly 22 in hooking the material box 40 for transportation can be improved. The hooking portion 222 is arranged perpendicular to the hook plate 221, so that the hooking portion 222 can hook up and drive the positioning member 43 while preventing the positioning member 43 from falling off from the hooking portion 222 during the movement of the material box 40, that is, preventing the material box 40 from falling off, thereby improving the transportation stability and efficiency.

[0067] In one possible implementation, see Figure 1-Figure 3 As shown, the positioning member 43 includes a fixing seat 431, a connecting shaft 432 and an anti-slip portion 433, and the fixing seat 431 is provided on the base 41 of the material box 40;

[0068] One end of the connecting shaft 432 is set on the fixing seat 431, and the other end is provided with an anti-slip portion 433. The hooking portion 222 is configured to hook the connecting shaft 432, and the anti-slip portion 433 is configured to prevent the hooking portion 222 from escaping from the connecting shaft 432.

[0069] Specifically, the fixing seats 431 of the positioning members 43 are evenly arranged on the base 41. The even distribution can make the base 41 of the entire material box 40 in a balanced state when the hook plate 221 hooks the corresponding positioning member 43; the setting direction of the fixing seats 431 is the same as the setting direction of the hook plate 221, that is, Figure 2 In the middle X direction, the connecting shaft 432 can be arranged perpendicularly to the fixing seat 431. When the hooking assembly 22 picks up the material box 40, the hook plate 221 is driven by the first driving mechanism 10 to move the hooking portion 222 to the side of the connecting shaft 432 corresponding to the positioning member 43, and after it drops in the X direction to a position where the entire hooking portion 222 is lower than the connecting shaft 432, it moves in the Y direction to move the hooking portion 222 to the position directly below the connecting shaft 432. Finally, the first driving mechanism 10 drives the hook plate 221 When rising in the X direction, the corresponding connecting shaft 432 can be hooked by the hooking portion 222, thereby hooking the entire material box 40. Furthermore, the anti-slip portion 433 can be of any shape and its cross-sectional area in the axial direction of the connecting shaft 432 is larger than the cross-sectional area of ​​the connecting shaft 432. When the hooking portion 222 hooks the connecting shaft 432, the hooking portion 222 is located between the fixing seat 431 and the anti-slip portion 433, and the anti-slip portion 433 prevents the hooking portion 222 from escaping from one side of the connecting shaft 432.

[0070] By cooperating with the hooking portion 222 and the connecting shaft 432 on the fixed seat 431, the hooking portion 222 hooks the connecting shaft 432 to hook the entire material box 40. At the same time, the anti-slip portion 433 at one end of the connecting shaft 432 can prevent the hooking portion 222 from escaping from the end of the connecting shaft 432, thereby improving the reliability of the hooking, thereby improving the stability and efficiency of the transportation of the material box 40 during the movement of the material box 40.

[0071] In one possible implementation, see Figure 1-Figure 3 As shown, a first driving member 211 is provided on the movable frame 21, and the hooking assembly 22 has at least two sets and is slidably installed on the movable frame 21 along the second direction. The driving ends of the first driving member 211 are respectively connected to at least two sets of hooking assemblies 22, and the first driving member 211 is configured to drive at least two sets of hooking assemblies 22 to approach or move away from each other along the second direction.

[0072] Specifically, the first driving member 211 can be a linear module, and one end of the hook plate 221 of at least two sets of hooking components 22 is installed on the linear guide rail of the linear module, and the linear guide rail is arranged along the second direction so that the first driving member 211 can adjust the distance between the two sets of hooking components 22.

[0073] Optionally, in order to reduce its own weight, the hook plate 221 can be provided with a weight-reducing hole 223 so that the hooking assembly 22 can move more flexibly on the guide rail of the first driving member 211 and facilitate the hooking portion 222 to hook the positioning member 43.

[0074] By setting up at least two sets of hooking components 22, it is possible to hook at least two material boxes at the same time, that is, to transport at least two material boxes at the same time, which effectively improves the transportation efficiency; at the same time, at least two sets of hooking components 22 are installed on the movable frame 21, and the first driving member 211 can drive at least two sets of hooking components 22 to move closer to or away from each other, and the distance between each set of hooking components 22 can be adjusted, that is, it is possible to hook at least two material boxes 40 with an uncertain distance in the second direction, which improves the applicability of the hooking component 22 to transport multiple material boxes 40 at the same time, and further improves the transportation efficiency.

[0075] It should be noted that the present application is mainly intended to protect the transport device for transporting the material box by hooking. The material box is not limited to the material box containing stacked sheets, but can also be a material box containing other materials (such as battery cells, sheets, film materials, etc.). As long as the positioning member 43 adapted to the hooking component 22 of the present application can be installed on the material box, the supporting plate 42 on the material box can also be in various forms, not limited to the above-mentioned inclined supporting plate 42, as long as it can carry the material.

[0076] In one possible implementation, see Figure 1-Figure 3As shown, the hooking mechanism 20 further includes at least one set of pressing assemblies 23 mounted on the movable frame 21 , and each set of pressing assemblies 23 is configured to press the laminates 30 in the magazine 40 hooked by the corresponding hooking assembly 22 onto the carrier plate 42 .

[0077] The pressing assembly 23 presses the stacking sheets 30 in the material box 40 hooked on the corresponding hooking assembly 22 onto the carrier plate 42 to ensure that the stacking sheets 30 will not fall off during the transportation of the material box 40, further improving the reliability of transportation and improving the transportation efficiency.

[0078] In one possible embodiment, the clamping assembly 23 includes a second driving member 231 and a pressure plate 232. The second driving member 231 is installed on the movable frame 21, and the pressure plate 232 is installed at an angle at the driving end of the second driving member 231. The second driving member 231 is configured to drive the pressure plate 232 to rise and fall vertically and / or move horizontally to press the stacking sheet 30 in the material box 40. The pressure plate 232 is inclined at the same angle and direction as the supporting plate 42.

[0079] Specifically, the second driving member 231 is a vertically arranged cylinder, the driving end of the cylinder is connected to the pressing plate 232, and the cylinder drives the pressing plate 232 to rise or fall relative to the supporting plate 42 to achieve the compression of the laminated sheets 30 in the material box 40.

[0080] Specifically, the pressing assembly 23 further includes a third driving member 233 and a fourth driving member 234 mounted on the movable frame 21. The driving end of the third driving member 233 is connected to the second driving member 231. The third driving member 233 is configured to drive the second driving member 231 to move horizontally in the second direction, thereby driving the pressure plate 232 on the second driving member 231 to move horizontally in the second direction, and adjusting its relative position with the pressure plate 232 in the second direction; the driving end of the fourth driving member 234 is connected to the third driving member 233. The fourth driving member 234 is configured to drive the third driving member 233 in the third direction ( Figure 3 The third and fourth drive members 233 and 234 move horizontally in the Z direction, thereby driving the second drive member 231 on the third drive member 233 to move in the third direction, that is, driving the pressure plate 232 to move horizontally in the third direction, adjusting its relative position with the pressure plate 232 in the third direction. By setting the third and fourth drive members 233 and 234, the pressure plate 232 can be adjusted to correspond horizontally with the support plate 42, more accurately pressing the stacking plate 30 against the support plate 42, improving the stability of the stacking plate 30 during transportation, and preventing the stacking plate 30 from shifting during movement and causing side misalignment. The third and fourth drive members 233 and 234 can both use linear modules, and the direction of the linear guide rails is consistent with their corresponding drive directions.

[0081] The second driving member 231 drives the pressure plate 232 to rise and fall vertically and / or move horizontally, so that the pressure plate 232 can be moved to the position corresponding to the stacking sheet 30 in the material box 40, thereby pressing down the stacking sheet 30 in the material box 40. At the same time, since the stacking sheet 30 carried by the supporting plate 42 is inclined, in order to ensure that the stacking sheet 30 can be stably pressed, the pressure plate 232 needs to be consistent with the inclination angle and direction of the supporting plate 42 to ensure that the stacking sheet 30 will not fall off during the transportation of the material box 40.

[0082] For further information, see Figures 1-4 The present application further provides a sorting machine, which includes a detection and sorting mechanism 50, a plurality of material receiving components 60, and a material box handling device as described in any one of the first aspects, wherein:

[0083] The inspection and sorting mechanism 50 is configured to receive and inspect silicon wafers, and classify the silicon wafers according to the inspection results and transport them to the discharge station M;

[0084] Several receiving assemblies 60 are located at the discharge station M. Each receiving assembly 60 is configured to carry a cassette 40 and receive silicon wafers with the same test results after being inspected and sorted by the inspection and sorting mechanism through the cassette 40. The silicon wafers are stacked in the cassette 40 to form a stack 30.

[0085] The hooking mechanism 20 is configured to hook a material box 40 located at the discharge station M and filled with laminates 30;

[0086] The first driving mechanism 10 is configured to drive the hooking mechanism 20 to move, so as to drive the material box 40 on the hooking mechanism 20 to move to the next process.

[0087] The sorting machine of the present application carries the material box 40 through the material receiving component 60 and receives the silicon wafers with the same detection result detected and classified by the detection and sorting mechanism 50 through the material box 40, so as to transport the stack 30 through the material box 40, so that the material box conveying device can hook the material box 40 through the hooking mechanism 20 to realize the conveying of the stack 30, without directly contacting the stack output by the detection and sorting mechanism 50 by clamping or adsorption. The method of hooking the material box 40 can effectively avoid the problem of picking failure or the material box 40 falling off during conveying, thereby greatly improving the conveying and production efficiency.

[0088] In one embodiment, see Figure 5 The receiving assembly 60 includes a base 61, a second driving mechanism 62 and at least two supporting members 63. The supporting members 63 are used to support the material box 40. The at least two supporting members 63 are respectively slidably mounted on the base 61. The driving ends of the second driving mechanism 62 are respectively connected to the at least two supporting members 63. The second driving mechanism 62 is configured to drive the at least two supporting members 63 to move alternately to the first position or the second position.

[0089] The first position is close to the discharge end of the detection and sorting mechanism 50 , and the material box 40 located at the first position is configured to receive the detected and classified silicon wafers output by the detection and sorting mechanism 50 ;

[0090] The second position is far away from the discharge end of the detection and sorting mechanism 50 , and the material box 40 located at the second position is configured to be hooked by the hooking mechanism 20 .

[0091] Specifically, the second driving mechanism 62 can drive each carrier 63 separately. The second driving mechanism 62 includes a slide rail 622 and a cylinder 621. Each carrier 63 is slidably installed on the corresponding slide rail 622. One end of the slide rail 622 is close to the discharge end of the detection and sorting mechanism 50, and the other end is away from the discharge end of the detection and sorting mechanism 50. The driving end of the cylinder 621 is connected to the carrier 63. The cylinder 621 drives the corresponding carrier 63 on the slide rail 622 to be close to or away from the discharge end of the detection and sorting mechanism 50. At least two carriers 63 can be arranged up and down. The second driving mechanism 62 drives the two carriers 63 arranged up and down to move alternately, which can realize the alternating reception and feeding of materials, thereby improving the discharge efficiency.

[0092] By driving at least two supporting members 63 to move alternately by the second driving mechanism 62 on the material receiving component 60, the same material receiving component 60 can alternately receive the silicon wafers after inspection and classification output by the inspection and sorting mechanism 50, thereby improving the efficiency of the material box 40 in receiving the stack 30. At the same time, the material receiving component 60 alternately transports the material box 40 containing the stack to a position away from the discharge end of the inspection and sorting mechanism 50 for the hooking mechanism 20 to hook and transport. The alternating feeding can effectively improve the handling efficiency of the material box handling device.

[0093] In one embodiment, see Figure 1-Figure 5 The sorting machine also includes a stacking detection mechanism 70, which is located at the next process. The stacking detection mechanism 70 is configured to receive a material box 40 containing stacking sheets 30 and deliver an empty material box 40. The first driving mechanism 10 is also configured to drive the hooking mechanism 20 to hook the empty material box 40 delivered by the stacking detection mechanism 70 and move it to the material receiving assembly 60 at the discharge station M.

[0094] Specifically, the stacking detection mechanism 70 can perform corresponding inspections on the stacking to eliminate unqualified stackings. During the inspection process or after the inspection is qualified, the stacking may be taken out from the material box due to corresponding processing needs. The empty material box with the stacking taken out will be sent out by the stacking detection mechanism 70. Therefore, the empty material box sent out can be transported to the discharge station M by the material box transporting device, and the empty material box can be carried by the material receiving component 60. Then, the empty material box receives the silicon wafers with the same inspection results after inspection and classification by the inspection and sorting machine, thereby realizing the repeated recycling of the material box and saving production costs. Furthermore, the material box conveying device can convey the material box filled with stacks to the stacking detection mechanism 70 at the detection and sorting mechanism 50. During the process of conveying the next stack from the stacking detection mechanism 70 back to the detection and sorting mechanism 50, the material box conveying device uses the return process to convey the empty material box, making full use of the conveying process of the material box conveying device. There is no need to specially transport the empty material box back to each detection and sorting mechanism 50, which effectively saves the conveying time and improves the overall conveying efficiency and production efficiency.

[0095] In one possible embodiment, there are at least two sets of detection and sorting mechanisms 50, and the at least two sets of detection and sorting mechanisms 50 are symmetrically arranged in two rows;

[0096] The sorting machine further includes a linear module 80 disposed between the two rows of detection and sorting mechanisms 50. The linear module 80 is configured to drive a material box transport device to move to the discharge station of each detection and sorting mechanism 50. The material box transport device is configured to sequentially hook the material box 40 containing the laminated sheets 30 from the discharge station of each detection and sorting mechanism 50.

[0097] The stacking detection mechanism 70 is located at the end of the moving stroke of the material box conveying device driven by the linear module 80. The material box conveying device is also configured to send the hooked material box 40 containing the stacking 30 into the stacking detection mechanism 70, and to receive the empty material box 40 sent out by the stacking detection mechanism 70 and transport it to the discharge station of each detection and sorting mechanism 50.

[0098] The optional working process of sorting in the embodiment of the present application is:

[0099] Two rows of symmetrically arranged inspection and sorting mechanisms 50 receive and inspect silicon wafers, and sort and send the wafers to the discharge station M according to the inspection results.

[0100] The receiving assembly 60 at the discharge station M of each detection and sorting mechanism 50 receives an empty material box 40. The empty material box 40 can be an empty material box 40 transported from the stacking detection mechanism 70 by the material box transporting device, or an empty material box 40 from other areas. The receiving assembly 60 receives the stacking sheets 30 of the same result sent out by the corresponding detection and sorting mechanism 50 through the empty material box 40, and transports the material box 40 containing the stacking sheets 30 to the discharge end away from the detection and sorting mechanism 50, so as to facilitate the material box transporting device to carry it.

[0101] The hooking mechanism 20 of the material box transporting device moves under the drive of the first driving mechanism 10 and hooks the material box 40 with the laminate 30 installed on the material receiving assembly 60;

[0102] After the linear module 80 drives the first drive mechanism 10 to move to a position close to the stacking detection mechanism 70, the first drive mechanism 10 drives the hooking mechanism 20 to move to the material receiving station of the stacking detection mechanism 70. The hooking mechanism 20 places the material box 40 containing the stacking 30 on the material receiving station of the stacking detection mechanism 70;

[0103] The first driving mechanism 10 drives the hooking mechanism 20 to move to the empty material box discharge point of the stacking detection mechanism 70, hooks the empty material box and moves it to each detection and sorting mechanism 50 that needs an empty material box under the drive of the linear module 80. The empty material box is received by the corresponding material receiving component 60 to realize the repeated recycling of the material box.

[0104] In this embodiment, multiple sets of detection and sorting mechanisms 50 are coordinated with the material box handling device, so that the material box handling device can continuously transport the material box containing stacked sheets at the discharge station to the stacking detection mechanism 70 for inspection, thereby improving the overall production efficiency. The detection and sorting mechanisms 50 are symmetrically arranged on both sides of the linear module 80. Under the drive of the linear module 80, the material box handling device can move to each detection and sorting mechanism 50 to hook the material box 40 containing stacked sheets 30, and can also receive the empty material box 40 sent by the stacking detection mechanism 70 and transport it to the discharge station of each detection and sorting mechanism 50. The detection and sorting mechanism 50 and the stacking detection mechanism 70 cooperate with the linear module 80 to drive the moving stroke arrangement of the material box handling device, so that the end of the material box handling device only needs to move in the same direction to realize the handling process, which can effectively improve the handling efficiency and handling accuracy of the material box handling device, thereby improving the overall production efficiency.
