[0031] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0032] This utility model provides a sorting mechanism for sorting soft boards, including a machine base 11, a conveying assembly 12 located within the machine base 11 for conveying pallets, lifting devices 13 located on both sides of the conveying assembly 12, and a gripping device. The lifting device 13 includes a first lifting assembly 131 for placing empty pallets, a second lifting assembly 132 for placing empty pallets, a third lifting assembly 133 for placing defective products, and a fourth lifting assembly 134 for placing qualified soft boards. The first lifting assembly 131 and the second lifting assembly 132 are located on one side of the conveying assembly 12, and the third lifting assembly 133 and the fourth lifting assembly 134 are located on the other side of the conveying assembly 12. The gripping device includes a robotic arm 141 located between the third lifting assembly 133 and the fourth lifting assembly 134, a first suction assembly 142 installed on the side wall of the machine base 11 and located on one side of the first lifting assembly 131 and the third lifting assembly 133, and a second suction assembly 143 installed on the side wall of the machine base 11 and located between the second lifting assembly 132 and the fourth lifting assembly 134.

[0033] The machine 11 is used to install the conveying assembly 12, the lifting device 13, and the gripping device. The first lifting assembly 131 and the second lifting assembly 132 of the lifting device 13 are both used to place empty pallets. The third lifting assembly 133 is used to place defective flexible boards, and the fourth lifting assembly 134 is used to place qualified flexible boards. The first suction assembly 142 is used to move the empty pallets from the first lifting assembly 131 onto the third lifting assembly 133. The second suction assembly 143 is used to place empty pallets from the conveying assembly 12 onto the second lifting assembly 132 and to move the empty pallets from the second lifting assembly 132 onto the fourth lifting assembly. On 134, the inspected flexible boards are placed on a tray and moved by the conveyor assembly 12 to below the robot arm 141. The robot arm 141 is used to place defective flexible boards on the tray of the third lifting assembly 133 and qualified flexible boards on the tray of the fourth lifting assembly 134. After the flexible boards are inspected, they are moved on the tray to below the robot arm 141 by the conveyor assembly 12. The first suction assembly 142 moves the empty tray of the first lifting assembly 131 to the third lifting assembly 133, and the second suction assembly 143 moves the empty tray of the second lifting assembly 132 to the fourth lifting assembly 134. On platform 34, robotic arm 141 places defective soft boards onto the tray of the third lifting assembly 133 and qualified soft boards onto the tray of the fourth lifting assembly 134. When the tray of the third lifting assembly 133 is full, the first suction assembly 142 moves an empty tray from the first lifting assembly 131 to the third lifting assembly 133. When the tray of the fourth lifting assembly 134 is full, the second suction assembly 143 moves an empty tray from the second lifting assembly 132 to the fourth lifting assembly 134. Simultaneously, as the number of empty trays on the first lifting assembly 131 and the second lifting assembly 132 decreases... The first lifting assembly 131 and the second lifting assembly 132 raise the empty trays to facilitate the first suction assembly 142 and the second suction assembly 143 to pick them up. Similarly, when the trays on the third lifting assembly 133 and the fourth lifting assembly 134 increase, the third lifting assembly 133 and the fourth lifting assembly 134 lower, so that the trays on the third lifting assembly 133 and the fourth lifting assembly 134 are kept at the same height, which facilitates the robot arm 141 to place the soft boards. Through the above operations, the manual operation is effectively reduced. While maintaining the same picking efficiency, the accuracy of picking can also be guaranteed, and the efficiency of picking soft boards can be greatly improved.

[0034] Please refer to Figure 6 , Figure 6This is a perspective view of the first suction assembly of the sorting mechanism of this utility model. Both the first suction assembly 142 and the second suction assembly 143 include a fixed frame 1421 fixed to the side wall of the machine base 11, a mounting base 1423 movable on the fixed frame 1421, a first motor 1422 mounted on the fixed frame 1421 for driving the mounting base 1423 to move on the fixed frame 1421, and a suction cup connected to the mounting base 1423. The first suction assembly 142 is used to suction empty trays from the first lifting assembly 131 and place them on the third lifting assembly 133. The second suction assembly 143 is used to transfer empty trays from the first lifting assembly 131 to the third lifting assembly 133. The empty tray on the feeding component 12 is picked up and placed on the second lifting component 132, and the empty tray on the second lifting component 132 is picked up and placed on the fourth lifting component 134. The fixing frame 1421 is used to fix it on the side wall of the machine base 11, and also facilitates the movement of the mounting base 1423. The first motor 1422 is used to drive the mounting base 1423 to move on the fixing frame 1421. The suction cup moves with the fixing frame 1421, thereby driving the suction cup to pick up the empty tray from the first lifting component 131 and place it on the third lifting component 133, and the suction cup to pick up the empty tray from the second lifting component 132 and place it on the fourth lifting component 134.

[0035] The suction cup includes a first cylinder 1424 fixed on the mounting base 1423, a first fixing plate 1425 mounted on the first cylinder 1424, and a plurality of first suction nozzles 1426 mounted on the first fixing plate 1425. The first cylinder 1424 is used to drive the first fixing plate 1425 away from or towards the empty tray. When the first suction nozzles 1426 pick up the empty tray, the first cylinder 1424 drives the first fixing plate 1425 to rise, preventing the first fixing plate 1425 from hitting obstacles during the movement and causing the empty tray to fall. At the same time, since there are multiple first suction nozzles 1426, multiple first suction nozzles 1426 simultaneously suction multiple positions of the empty tray, preventing the empty tray from falling during the movement.

[0036] Please refer to Figure 3 , Figure 3This is a perspective view of the robotic arm of the sorting mechanism of this utility model. The robotic arm 141 includes a main unit 1411, a swing arm 1412 that is oscillatingly connected to the main unit 1411 and can move between the third lifting assembly 133 and the fourth lifting assembly 134, and a robotic arm 1413 connected to the swing arm 1412. The robotic arm 1413 is provided with a suction rod 1414 that can be raised and lowered on the robotic arm 1413 and a second suction nozzle 1415 installed on the suction rod 1414. The suction rod 1414 can be raised and lowered on the robotic arm 1413. The main unit 1411 is used to control the swing arm 1412 to swing, so that the swing arm 1412 moves towards the third lifting assembly 133 and the fourth lifting assembly 134. The robotic arm 1413 is installed on the swing arm 1412 and follows the swing arm. 1412 moves, and simultaneously, the robotic arm 1413 is equipped with a suction rod 1414 and a second suction nozzle 1415. When the swing arm 1412 moves to the soft board above the conveying assembly 12, the second suction rod 1414 descends, driving the second suction nozzle 1415 to pick up the soft board. After the second suction nozzle 1415 picks up the soft board, the second suction rod 1414 rises, and the swing arm 1412 moves towards the third lifting assembly 133 or the fourth lifting assembly 134. When the swing arm 1412 is above the third lifting assembly 133 or the fourth lifting assembly 134, the suction rod 1414 descends again, so that the second suction nozzle 1415 can place the soft board on the tray of the third lifting assembly 133 or the tray of the fourth lifting assembly 134. The suction rod 1414 rises again, so that it can pick up the soft board from the conveying assembly 12 again.

[0037] Please refer to Figure 5 , Figure 5 This is a perspective view of the conveying components of the sorting mechanism of this utility model. The first lifting component 131, the second lifting component 132, the third lifting component 133, and the fourth lifting component 134 each include a second fixed plate 1311, a second motor 1312 mounted at the bottom of the second fixed plate 1311, a placement plate 1313 located above the second fixed plate 1311, and a lead screw 1314 connected to the second motor 1312 with one end passing through the second fixed plate 1311 and connecting to the placement plate 1313. The second motor 1312 is used to drive the lead screw 1314 to rotate, thereby raising and lowering the placement plate 1313. The second fixed plate 1311 is used to mount the second motor 1312. The placement plate 1313 is used to place the tray. The lead screw 1314 is connected to the second motor 1312. The second motor 1312 drives the lead screw 1314 to rise and fall. The lead screw 1314 drives the placement plate 1313 to rise and fall, thereby realizing the raising or lowering of the trays on the first lifting assembly 131, the second lifting assembly 132, the third lifting assembly 133, and the fourth lifting assembly 134.

[0038] In this embodiment, a synchronous belt is also provided between the second motor 1312 and the lead screw 1314. The second motor 1312 drives the lead screw 1314 to rotate through the synchronous belt, so that when the second motor 1312 drives the lead screw 1314 to rise and fall, the placement plate 1313 follows the lead screw 1314 to rise and fall.

[0039] Multiple limiting posts 1315 are also provided at the corners of the placement plate 1313. One end of the limiting post 1315 passes through the second fixing plate 1311. The limiting post 1315 is used to limit the placement plate 1313. When the lead screw 1314 drives the placement plate 1313 to rise or fall, the limiting plate 1316 is used to prevent the placement plate 1313 from tilting, so that the placement plate 1313 can rise or fall stably.

[0040] Limiting plates 1316 are provided on both sides of the second fixing plate 1311. The limiting plates 1316 are used to limit the position of the pallet. When an empty pallet is placed, the adjacent limiting plates 1316 can position the corner of the empty pallet so that the empty pallet is placed in a relatively fixed position.

[0041] The conveying assembly 12 includes a first long strip 121 and a second long strip 122 located on one side of the first long strip 121. A third motor 123 and a conveyor belt 124 driven and connected to the third motor 123 are provided on both the first long strip 121 and the long strip. The first long strip 121 and the second long strip 122 are used to install the third motor 123 and the conveyor belt 124. The third motor 123 is used to drive the conveyor belt 124 to rotate. The conveyor belt 124 on the first long strip 121 and the second long strip 122 thereby drives the pallet to move, so that the soft board on the pallet can be moved under the robot arm 141, so that the robot arm 141 can pick up the soft board.

[0042] The bottom of the first long strip 121 is also provided with multiple guide rails 125. The first long strip 121 can move away from or towards the second long strip 122 on the guide rails 125. The guide rails 125 are used to adjust the distance between the first long strip 121 and the second long strip 122 to accommodate the placement of pallets of different sizes and soft boards of different sizes.

[0043] The side wall of the machine tool 11 is also provided with a limiting component 111, which is located below the second suction component 143. The limiting component 111 includes a second cylinder installed on the side wall of the machine tool 11 and a baffle connected to the second cylinder. The second cylinder drives the baffle to move to limit the tray below the robot arm 141. The second cylinder is used to drive the baffle to move to block the tray. On the one hand, it is used to prevent the tray on the conveying component 12 from moving, so that the robot arm 141 can pick up the soft board. On the other hand, when detecting soft boards of different specifications, the specifications of the corresponding trays are also different. The second cylinder drives the baffle to limit the tray below the robot arm 141, so that the robot arm 141 can pick it up.

[0044] Working principle: After the flexible board is inspected, it is conveyed along with the tray to the area below the robot arm 141 via the conveying assembly 12. Since the first lifting assembly 131, the second lifting assembly 132, the third lifting assembly 133, and the fourth lifting assembly 134 have the same structure, and the first suction assembly 142 and the second suction assembly 143 have the same structure, taking the first lifting assembly 131 and the first suction assembly 142 as examples, the first motor 1422 drives the mounting base 1423 to move on the fixed frame 1421. The mounting base 1423 moves towards the first lifting assembly 131 on the fixed frame 1421. At the same time, the suction cup moves along with the mounting base 1423. When the suction cup is above the first lifting assembly 131, the first cylinder 1424 drives the first fixed plate 1425 to move down, so that the first suction nozzle 1426 can pick up the empty tray on the first lifting assembly 131. After the first suction nozzle 1426 picks up the tray, the first cylinder 1424 rises, and the first motor 1422 drives the mounting base 1423 to move towards the second lifting assembly 132.

[0045] Furthermore, after the first suction nozzle 1426 picks up the tray, the second motor 1312 drives the lead screw 1314 to rotate, thereby moving the placement plate 1313 upward, and thus moving the tray on the placement plate 1313 to a set position, so that the first suction nozzle 1426 can pick it up again. Further, when the tray on the first suction nozzle 1426 is above the third lifting assembly 133, the first cylinder 1424 picks up the tray and moves it downward, so that the first suction nozzle 1426 can place the tray in the set position. Similarly, the second suction assembly 143 picks up the tray on the second lifting assembly 132 and moves it to the fourth lifting assembly 134. Further, the main unit 1411 drives the swing arm 1412 to move above the flexible plate on the moving assembly, and the robotic arm 1413 drives the suction rod 1414 to descend, so that the second suction nozzle 1415 on the suction rod 1414 picks up the flexible plate. After the second suction nozzle 1415 picks up the flexible plate, the main unit 1411 drives... The swing arm 1412 moves toward the third lifting assembly 133 or the fourth lifting assembly 134. If the soft board is defective, the swing arm 1412 moves toward the third lifting assembly 133. If the soft board is qualified, the swing arm 1412 moves toward the fourth lifting assembly 134. When the swing arm 1412 is above the third lifting assembly 133 or the fourth lifting assembly 134, the suction rod 1414 descends and drives the second suction nozzle 1415 to descend, so as to facilitate placing the soft board on the tray on the third lifting assembly 133 or the fourth lifting assembly 134. Furthermore, after the soft board on the tray on the conveying assembly 12 is picked up, the second suction assembly 143 picks up the empty tray on the conveying assembly 12 and places it on the second lifting assembly 132, thereby reducing manual operation. While maintaining the same picking efficiency, it can also effectively ensure the picking accuracy and greatly improve the picking efficiency of soft boards.

[0046] The sorting mechanism of this preferred embodiment uses a conveying component to move the inspected soft boards via a pallet to below the robotic arm. The first suction component picks up an empty pallet from the first lifting component and transfers it to the third lifting component. The second suction component picks up an empty pallet from the second lifting component and transfers it to the fourth lifting component. The robotic arm picks up qualified products and places them on the pallet of the fourth lifting component, and picks up defective products and transfers them to the third lifting component. This reduces manual operation and, while maintaining the same sorting efficiency, effectively ensures the accuracy of sorting, significantly improving the efficiency of sorting soft boards.

[0047] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
