Technical Field

[0001] This application relates to the technical field of automatic feeding, and in particular to a feeding device with a feeding tray. Background Technology

[0002] In mass production scenarios such as electronics and automotive parts, double-layer material trays are common material carriers.

[0003] In traditional production, the transfer and feeding of material trays rely on manual labor, which can easily lead to material shortages and affect production efficiency. Summary of the Invention

[0004] To improve production efficiency, this application provides a feeding device with a feeding tray.

[0005] This application provides a feeding device with a feeding tray, which adopts the following technical solution: A material feeding device with a tray includes an AGV trolley, a main body, a tray conveying mechanism, a tray lifting mechanism, a tray receiving and feeding mechanism, an empty tray stacking mechanism, and an empty tray return mechanism. The tray conveying mechanism, the tray lifting mechanism, the tray receiving and feeding mechanism, the empty tray stacking mechanism, and the empty tray return mechanism are all mounted on the main body. The AGV trolley can transfer trays to the tray conveying mechanism, and trays on the empty tray return mechanism can be transferred to the AGV trolley.

[0006] By adopting the above technical solution, the AGV trolley transfers stacked trays containing materials to the tray conveying mechanism. Then, the tray lifting mechanism transfers one tray to the receiving tray mechanism, where the material is transferred out. Empty trays then enter the empty tray stacking mechanism. When the number of empty trays in the stacking mechanism reaches a certain amount, the empty trays enter the empty tray return mechanism, which finally transfers them back to the AGV trolley. The tray-feeding equipment provided in this application replaces manual product handling, achieving fully automated "tray transfer → feeding → empty tray recycling," effectively saving labor and improving production efficiency.

[0007] Optionally, the material tray conveying mechanism includes a first conveyor frame, a first conveyor belt, a first detection sensor, and a first blocking cylinder. The first conveyor frame is disposed on the main body, and the first conveyor belt is rotatably disposed on the first conveyor frame. The first detection sensor is disposed on the first conveyor frame, and the first blocking cylinder is disposed on the first conveyor frame.

[0008] By adopting the above technical solution, the AGV trolley transfers the material tray to the first conveyor belt. When the first detection sensor detects the presence of the material tray, the first conveyor belt will drive the material tray to move. The first blocking mechanism is activated, and the first blocking cylinder blocks the material tray, which facilitates the subsequent material tray lifting mechanism to transfer the material tray.

[0009] Optionally, the tray lifting mechanism includes a linear motor module, a first lifting block, a drive cylinder, and grippers. The linear motor module is mounted on the main body, and the first lifting block is mounted on the slide of the linear motor module.

Multiple limiting blocks are provided, and all of the multiple limiting blocks are provided on the second support block. The adjustment cylinder is provided on the second support block, and the multiple limiting blocks and the adjustment cylinder form a placement space on the second support block.

[0014] By adopting the above technical solution, when the material tray is transferred to the second support block, it will be located in the placement space, and multiple limiting blocks will abut the material tray; then the adjusting cylinder is activated, and the piston rod of the adjusting cylinder abuts the material tray. In this way, multiple limiting blocks and adjusting blocks will fix the position of each material tray, which facilitates the subsequent transfer of materials.

[0015] Optionally, the empty material tray return mechanism includes a second conveyor frame, a second conveyor belt, a second detection sensor, and a second blocking cylinder. The second conveyor frame is mounted on the main body, and the second conveyor belt is rotatably mounted on the second conveyor frame. The second detection sensor is mounted on the second conveyor frame, and the second blocking cylinder is mounted on the second conveyor frame.

[0016] By adopting the above technical solution, the empty tray is transferred to the second conveyor. When the second detection sensor detects the presence of the tray, the second conveyor belt will drive the tray to move. When a tray enters the AGV, the second blocking cylinder is activated, which can block subsequent trays.

[0017] Optionally, the empty pallet stacking mechanism includes a fixed frame, a second lifting block, a pallet limiting block, a first adjusting cylinder, and a first driving assembly. Two fixed frames are provided, both mounted on the main body. Two second lifting blocks are provided, each slidingly mounted on one of the two fixed frames. The pallet limiting block slides on the second lifting block. The first adjusting cylinder is mounted on the second lifting block, and its piston rod is connected to the pallet limiting block. Both second lifting blocks on the fixed frames are connected to the first driving assembly.

[0018] By adopting the above technical solution, the first adjusting cylinder is started, and the piston rod of the first adjusting cylinder drives the material tray limit block to move, so that the material tray limit blocks on the two fixed frames are pressed against the material tray; then the first driving component is started, and the first driving component drives the two material tray limit blocks to move, and the two material tray limit blocks will drive the material tray to move.

[0019] Optionally, the fixing frame includes a fixing plate and a first guide shaft. Two fixing plates are provided, and both fixing plates are connected to the main body.

The connecting block is mounted on the adjustment block, and the pressing block is slidably mounted on the connecting block. The adjustment assembly is mounted on the third lifting block and connected to the pressing block.

[0022] By adopting the above technical solution, when the empty pallet stacking mechanism transfers the pallets out, the second adjusting cylinder is activated. The piston rod of the second adjusting cylinder drives the adjusting block to move, so that a part of the pallet on the upper part of the pallet to be transferred enters the clamping groove, and the pressing block is positioned between the pallet on the upper part of the pallet to be transferred and the pallet to be transferred. The second driving component is activated, which drives the third lifting block to move. The adjusting block on the third lifting block drives the pallet on the upper part of the pallet to be transferred to move, and the adjusting component will make the pressing block move closer to the pallet to be transferred, reducing the phenomenon of pallets sticking together and making it difficult to transfer.

[0026] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0027] This application discloses a feeding device with a feeding tray. Example 1

[0028] refer to Figure 1 A material feeding device with a material tray includes an AGV trolley and a main body 1. The main body 1 is equipped with a material tray conveying mechanism 2, a material tray lifting mechanism 3, a material tray receiving and feeding mechanism 4, an empty tray stacking mechanism 6, and an empty material tray return mechanism 5.

[0029] The AGV transfers stacked pallets 8 containing materials to the pallet conveying mechanism 2. Then, the pallet lifting mechanism 3 transfers one pallet 8 to the receiving and conveying pallet mechanism 4, where the material is transferred out. The empty pallets 8 then enter the empty pallet stacking mechanism 6. When the number of empty pallets 8 in the empty pallet stacking mechanism 6 reaches a certain amount, the empty pallets 8 enter the empty pallet return mechanism. Finally, the empty pallet return mechanism transfers the empty pallets 8 to the AGV.

[0030] refer to Figure 2 The material tray 8 includes a base plate 81, on which four first support columns 82 are fixedly connected. A second support column 83 is fixedly connected to the end of each first support column 82 away from the base plate 81. A slot is provided on the side of the base plate 81 away from the first support columns 82 to engage with the second support column 83. The second support column 83 on the base plate 81 engages with the slot on the adjacent base plate 81, allowing two material trays 8 to be stacked.

[0031] As needed, the AGV transfers multiple stacked trays 8 containing materials to the tray conveying mechanism 2.

[0032] refer to Figure 1 and Figure 3 The material conveying mechanism 2 includes a first conveyor frame 21 fixedly connected to the main body 1. The first conveyor frame 21 includes two first conveyor blocks fixedly connected to the main body 1. Each first conveyor block is rotatably connected to a first conveyor belt 22. Multiple first detection sensors 23 are fixedly connected to one of the first conveyor blocks. Multiple first blocking cylinders 24 are fixedly connected to the first conveyor block.

[0033] The AGV transfers multiple stacked trays 8 containing material onto two first conveyor belts 22. When the first detection sensor 23 detects the presence of the trays 8, the two first conveyor belts 22 move the stacked trays 8. A first blocking cylinder 24, located away from the feed end of the first conveyor belt 22, is activated to block the stacked trays 8. The piston rod of the first blocking cylinder 24 abuts against the bottom plate 81 of the tray 8 closest to the first conveyor belt 22. Other first blocking cylinders 24 block trays 8 located at other positions on the first conveyor belt 22. This facilitates the transfer of material-filled trays 8 by the tray lifting mechanism 3.

[0034] refer to Figure 1 and Figure 4 The material tray lifting mechanism 3 includes a linear motor module 31 fixedly connected to the main body 1. The linear motor module 31 is vertically arranged. A first lifting block 32 is fixedly connected to the slide of the linear motor module 31. Two drive cylinders are fixedly connected to the first lifting block 32. The two drive cylinders are arranged in opposite directions. A gripper 33 is connected to the piston rod of each drive cylinder.

[0035] When the first blocking cylinder 24 blocks the material tray 8, the linear motor module 31 is activated. The slide of the linear motor module 31 drives the first lifting block 32 to move, positioning the material tray 8, which is away from the first conveyor belt 22, between the two grippers 33. Then, the two drive cylinders are activated, and their piston rods drive the two grippers 33 to move towards each other, clamping the base plate 81 of the material tray 8, which is away from the first conveyor belt 22. The linear motor module 31 is then activated again, and its slide drives the first lifting block 32 to rise. The two grippers 33 on the first lifting block 32 then move the material tray 8, positioning it in a position convenient for the material tray receiving and feeding mechanism 4 to transfer.

[0036] refer to Figure 1 and Figure 5 The feeding tray mechanism 4 includes a connecting frame 41, which includes two mounting blocks fixedly connected to the main body 1. The distance between the two mounting blocks is greater than the distance between the two grippers 33, that is, when the two grippers 33 hold the tray 8, the two grippers 33 can pass through the space between the two mounting blocks. A first support block 42 is slidably disposed on the connecting frame 41, and the first support block 42 is slidably connected to the two mounting blocks. A first moving cylinder is fixedly connected to one of the mounting blocks, and the piston rod of the first moving cylinder moves with the first adjusting block 72.

[0037] A fixed rail 46 is fixedly connected to the first support block 42, and the end of the fixed rail 46 away from the gripper 33 extends out of the connecting frame 41; a second support block 43 is slidably connected to the fixed rail 46; a second moving cylinder 44 is fixedly connected to the second support block 43, and the piston rod of the second moving cylinder 44 is connected to the first support block 42.

[0038] An adjustment limiting component 45 is provided on the second support block 43. The adjustment limiting component 45 includes three limiting blocks 451 fixedly connected to the second support block 43. An adjustment cylinder 452 is fixedly connected to the second support block 43. The adjustment cylinder 452 and the three limiting blocks 451 are located at the four corners of the second support block 43. The adjustment cylinder 452 and the three limiting blocks 451 form a placement space on the second support block 43.

[0039] Two grippers 33 holding the tray 8 pass between the two mounting blocks and are positioned above the second support block 43. Then, the first moving cylinder and the second moving cylinder 44 are activated. The piston rod of the first moving cylinder drives the first support block 42 to move. When the piston rod of the second moving cylinder 44 extends out of the cylinder body, the cylinder body of the second moving cylinder 44 drives the second support block 43 to move, so that the second support block 43 moves to below the two grippers 33, and the tray 8 held by the two grippers 33 is positioned directly above the placement space. Next, the linear motor module 31 is activated, so that the tray 8 held by the two grippers 33 is positioned within the placement space of the second support block 43, that is, the bottom plate 81 of the tray 8 abuts against the second support block 43, and all three limiting blocks 451 abut against the tray 8. Then, the adjusting cylinder 452 is activated, and the piston rod of the adjusting cylinder 452 presses against the bottom plate 81 of the tray 8 located in the placement space. At this time, the additional robotic arm will transfer the material on the tray 8 out of the tray 8. Then, start the first moving cylinder and the second moving cylinder 44 to make the second support block 43 extend out of the connecting frame 41, and the second support block 43 is located at the end of the fixed rail 46 away from the gripper 33; and at this time, start the linear motor module 31 so that the two grippers 33 can clamp the material tray 8 located on the first conveyor belt 22.

[0040] refer to Figure 1 and Figure 6 The empty material tray return mechanism 5 includes two fixed frames 61, each of which includes two fixed plates 611, which are vertically distributed. Two first guide shafts 612 are arranged between the two fixed plates 611, with each end of the first guide shaft 612 connected to one of the two fixed plates 611. A second lifting block 62 is arranged between the two fixed plates 611, and the second lifting block 62 has a first through hole for the first guide shafts 612 to pass through. A first groove is formed on the second lifting block 62, and a material tray limiting block 63 is slidably connected within the first groove. A first adjusting cylinder is fixedly connected to the second lifting block 62, with the piston rod of the first adjusting cylinder positioned between the piston rod and the material tray limiting block 63.

[0041] Two fixed frames 61 are provided with a first drive assembly 64. The first drive assembly 64 includes a first lead screw 641. The two ends of the first lead screw 641 are rotatably connected to the two fixed plates 611 respectively. The first lead screw 641 passes through the second lifting block 62 and is threadedly connected to the second lifting block 62. The upper ends of the first lead screw 641 on both fixed frames 61 are fixedly connected to a first drive wheel 642. A first connecting plate 643 is provided on the fixing plate 611 at the upper end of the two fixing brackets 61. The two ends of the first connecting plate 643 are respectively connected to the fixing plate 611 at the upper end of the two fixing brackets 61. A first drive motor 644 and a first reducer are fixedly connected to the first connecting plate 643. The output shaft of the first drive motor 644 is connected to the input end of the first reducer. A second drive wheel 645 is fixedly connected to the output shaft of the first reducer. A first drive belt 646 is fitted on the second drive wheel 645 and the two first drive wheels 642. The second drive wheel 645 and the two first drive wheels 642 all abut against the first drive belt 646. A first tensioning wheel 647 is rotatably connected to the first connecting plate 643. The first tensioning wheel 647 abuts against the first drive belt 646.

[0042] When the second support block 43 is located at the end of the fixed rail 46 away from the gripper 33, the material tray 8 without material on the second support block 43 will be located between the two material tray limit blocks 63. The first adjusting cylinder is activated, and the first adjusting cylinder drives the material tray limit block 63 to move, so that the two material tray limit blocks 63 on the two fixed frames 61 move towards each other, so that the two material tray limit blocks 63 clamp the bottom plate 81 of the material tray 8 located above the second support block 43. Start the first drive motor 644. The first drive motor 644 drives the second drive wheel 645 to rotate through the first reducer. The second drive wheel 645 drives the first drive belt 646 to rotate. The first drive belt 646 drives the first drive wheel 642 to rotate. The first drive wheel 642 drives the first lead screw 641 to rotate. The first lead screw 641 drives the second lifting block 62 to move. The second lifting block 62 drives the material tray limit block 63 to move. In this way, the two material tray limit blocks 63 will drive the empty material tray 8 to move upward, so that the empty material tray 8 is no longer located on the second support.

[0043] refer to Figure 1 and Figure 7 The empty tray return mechanism 5 includes a second conveyor frame 51 located below the second support block 43. The second conveyor frame 51 includes two second conveyor blocks fixedly connected to the main body 1, and a second conveyor belt 52 is rotatably connected to each second conveyor block. When the two tray limiting blocks 63 clamp the tray 8, the distance between the two tray limiting blocks 63 is greater than the distance between the two second conveyor belts 52, so that the tray 8 can be located on the two first conveyor belts 22. Multiple second detection sensors 53 are fixedly connected to one of the second conveyor blocks; multiple second blocking cylinders 54 are fixedly connected to the second conveyor block.

[0044] When a certain number of trays 8 are above the trays 8 held by the two tray limit blocks 63, and there are trays 8 with material on the second support block 43 during the material transfer process, the first drive motor 644 is activated, causing the two second lifting blocks 62 to descend. The two tray limit blocks 63 will then drive the empty trays 8 to move, and the bottom plate 81 of the empty trays 8 held by the two tray limit blocks 63 will abut against the two second conveyor belts 52. When the second detection sensor 53 detects that there are trays 8 on the second conveyor belt 52, the second conveyor belt 52 will drive the trays 8 to move, transferring the trays 8 on the second conveyor belt 52 to the AGV trolley, allowing the AGV trolley to transfer the empty trays 8.

A fourth bevel gear 778 that meshes with the third bevel gear 775 is keyed to the third rotating shaft 777 located in the first cavity 722. The second rotating shaft 776 is keyed to one end of the second shaft located in the second cavity, and the third lifting block 71 is rotatably connected to the fourth rotating shaft 7710. One end of the fourth rotating shaft 7710 is located in the second cavity, and the fourth rotating shaft 7710 located in the second cavity is keyed to the sixth bevel gear 7711 that meshes with the fifth bevel gear 779. The end of the fourth rotating shaft 7710 away from the sixth bevel gear 7711 is located outside the third lifting block 71 and is keyed to the adjusting gear 7712. The fixed plate 611 is fixedly connected to the fixed rack 7713 that meshes with the adjusting gear 7712.

[0053] When there are multiple trays 8 above the tray 8 held by the two tray limit blocks 63, and the multiple trays 8 are not placed on the second conveyor belt 52 at the same time, it is possible to connect when there are five empty trays 8 on the tray 8 stacking mechanism, the two tray limit blocks 63 hold the first tray 8, and from bottom to top, the second tray 8, the third tray 8, the fourth tray 8 and the fifth tray 8, and only the first tray 8, the second tray 8 and the third tray 8 are transferred to the second conveyor belt 52. Before the first tray 8 touches the second conveyor belt 52, the second adjusting cylinder 73 is activated. The second adjusting cylinder 73 drives the adjusting block 72 to slide in the second groove 711 of the third lifting block 71, so that the bottom plate 81 of the fourth tray 8 enters the clamping groove 721 of the adjusting block 72 and engages with the clamping groove 721. When the adjusting block 72 moves, the adjusting block 72 drives the connecting block 74 to move, and the connecting block 74 drives the pressing block 75 to move, so that the end of the pressing block 75 away from the adjusting block 72 is located between the third tray 8 and the fourth tray 8, and the pressing block 75 does not touch the bottom plate 81 of the third tray 8.

[0054] Then, the second drive motor 766 is started. The second drive motor 766 drives the fifth drive wheel 767 to rotate through the second reducer. The fifth drive wheel 767 drives the third drive belt 768 to rotate. The third drive belt 768 drives the fourth drive wheel 764 on the two fixed frames 61 to rotate. The fourth drive wheel 764 drives one of the second lead screws 761 to rotate. The third drive wheel 762 on this second lead screw 761 drives the second drive belt 763 to rotate. The second drive belt 763 drives the third drive wheel 762 on the other second lead screw 761 to rotate, so that the two second lead screws 761 on the same fixed frame 61 rotate synchronously. The four second lead screws 761 on the two fixed frames 61 will also rotate synchronously. The rotating second lead screw 761 drives the third lifting block 71 to move. The adjusting block 72 on the third lifting block 71 drives the fourth material tray 8 to move away from the third material tray 8, so that the fourth material tray 8 separates from the third material tray 8. When the third lifting block 71 moves, the fixed rack 7713 causes the adjusting gear 7712 to rotate. The adjusting gear 7712 drives the fourth rotating shaft 7710 to rotate. The sixth bevel gear 7711 on the fourth rotating shaft 7710 drives the fifth bevel gear 779 to rotate. The fifth bevel gear 779 drives the second rotating shaft 776 to rotate. The second rotating shaft 776 drives the third rotating shaft 777 to rotate. The third rotating shaft 777 drives the fourth bevel gear 778 to rotate. The fourth bevel gear 778 drives the... The rotation of the third bevel gear 775 drives the first rotating shaft 773 to rotate, which in turn drives the second bevel gear 774 to rotate. The second bevel gear 774 then drives the first bevel gear 772 to rotate, which in turn drives the third lead screw 771 to rotate. The third lead screw 771 then moves the lower pressure block 75, causing it to move away from the adjusting block 72. The lower pressure block 75 remains in contact with the third tray 8, thus better separating the third tray 8 from the fourth tray 8. Finally, the first tray 8 is transferred to the second conveyor belt 52, which then carries the first, second, and third trays 8 away. Alternatively, all five trays 8 can be transferred to the second conveyor belt 52 first, and then the two tray limiting blocks 63 clamp the third tray 8, while the base plate 81 of the fourth tray 8 remains engaged with the clamping groove 721 of the adjusting block 72. The second drive motor 766 is then activated to separate the fourth tray 8 from the third tray 8.

[0055] After the fourth tray 8 separates from the third tray 8, the two tray limiting blocks 63 clamp the bottom plate 81 of the fourth tray 8, and then the bottom plate 81 of the fourth tray 8 separates from the clamping groove 721 of the adjusting block 72.

[0056] In other embodiments, the adjusting block 72 does not have a clamping groove 721. When separating the third tray 8 from the fourth tray 8, the second adjusting cylinder 73 is activated, causing the pressing block 75 to abut against the bottom plate 81 of the third tray 8. A certain distance exists between the adjusting block 72 and the tray 8, preventing them from touching each other. Then, the five trays 8 are transferred to the second conveyor belt 52. The first drive motor 644 and the first adjusting cylinder are then activated, causing the two tray limiting blocks 63 to clamp the fourth tray 8. Next, only the first drive motor 644 is activated, causing the two tray limiting blocks 63 to move the fourth tray 8 away from the third tray 8, thus separating the third tray 8 from the fourth tray 8. During this period, the adjusting assembly 77 does not operate.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
