Description

Technical Field

[0001] This utility model relates to the technical field of neodymium iron boron processing equipment, and in particular to a lifting platform. Background Technology

[0002] Neodymium iron boron (NdFeB) is a magnetic material known as the "King of Magnets" due to its superior magnetic properties. NdFeB can be divided into sintered NdFeB and bonded NdFeB. Because the magnetic properties of sintered NdFeB are far superior to those of bonded NdFeB, sintered NdFeB is widely used in electronics, electrical machinery, medical devices, toys, packaging, hardware machinery, aerospace, and other fields. NdFeB is first pressed into shape in a magnetic field, and then sintered at high temperature in a vacuum sintering furnace. After cooling, it achieves densification, resulting in a product with high magnetic properties. Therefore, the entire process requires a sealed frame and nitrogen-filled conditions for oil removal and stacking operations to prevent oxidation of the NdFeB products.

[0003] However, the existing palletizing method involves directly stacking the packaged products layer by layer into a pallet using a robotic arm. Due to the fixed nature of the palletizing mechanism, the feeding of the graphite boxes containing the products into the palletizing mechanism, the feeding of the pallet into the palletizing mechanism, and the robotic arm's palletizing operation on the palletizing mechanism, there will be a lack of continuity between the operation of each mechanism. The limited space for the robotic arm to recycle the pallet also affects the quality and efficiency of palletizing. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting platform that controls the lifting and moving of the palletizing conveyor mechanism. When descending, it cooperates with the pallet feeding mechanism to first send the pallet onto the palletizing conveyor mechanism. When rising, it works in conjunction with the robotic arm to place the graphite boxes containing the products into the pallet for stacking. This lifting and moving linkage makes the palletizing operation simple and smooth, thereby improving the quality and efficiency of product palletizing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lifting platform, including a screw lifting mechanism, a stacking and conveying mechanism on the screw lifting mechanism, and a gantry truss transplanting mechanism correspondingly above the screw lifting mechanism. The screw lifting mechanism includes a lifting drive assembly, the output end of which is connected to a vertical screw. The stacking and conveying mechanism includes a conveyor line frame connected to the vertical screw, and a conveyor line is provided inside the conveyor line frame. The gantry truss transplanting mechanism includes a graphite box gripping mechanism with a horizontal linear module located above the vertical screw. A graphite box gripping mechanism with a vertical linear module is provided at the lower end of the horizontal linear module. A dual-purpose gripping mechanism for picking up and covering the graphite box is connected at the lower end of the vertical linear module.

[0006] Preferably, the lifting drive assembly base has a lifting motor in the middle, the output end of the lifting motor is connected to a main drive seat, both ends of the main drive seat are connected to driven drive seats, both ends of the driven drive seats are connected to a horizontal drive rod, the output end of the horizontal drive rod is engaged with the vertical lead screw, and the palletizing conveyor mechanism is connected to the middle of the vertical lead screw.

[0007] More preferably, the conveyor line frame has an installation groove in the middle to facilitate the installation of the conveyor line. The conveyor line includes a conveyor motor on the conveyor line frame and several drive rollers in the installation groove. The drive rollers are covered with a conveyor belt, and the output end of the conveyor motor is connected to the drive rollers by a chain or belt.

[0008] More preferably, the graphite box gripping mechanism includes a horizontal linear module comprising a support frame, with two horizontal support plates connected to the lower end of the support frame via a slider. One end of one horizontal support plate is provided with a horizontal moving motor, and a connecting rod is provided between the two horizontal support plates. The output end of the horizontal moving motor is connected to the horizontal support plate via a horizontal drag chain.

[0009] More preferably, the graphite box gripping mechanism longitudinal linear module includes a longitudinal support plate connected to the bottom of one end of the transverse support plate. The longitudinal support plate is equipped with a longitudinal moving motor, the output end of which is connected to a longitudinal drag chain. The bottom end of the longitudinal support plate is slidably connected to the box-removing and lid-adding dual-purpose gripping mechanism.

[0010] More preferably, the dual-purpose box-removing and lid-adding clamping mechanism includes a connecting frame, with a graphite box gripping and lifting cylinder connected to the lower end of the connecting frame. The output end of the graphite box gripping and lifting cylinder is laterally provided with a graphite box gripping cylinder, and the output end of the graphite box gripping cylinder is connected to a gripper.

[0011] In summary, the beneficial effects of this utility model are as follows: the lifting mechanism drives the palletizing conveyor to adjust its height. When descending, it cooperates with the pallet feeding mechanism to first send the pallet onto the palletizing conveyor. When ascending, it moves in conjunction with the gantry truss transfer mechanism, making it easy for the robot arm to grab the graphite boxes containing the products and place them together in the pallet for lifting and palletizing operations. This lifting linkage makes the palletizing operation simple and smooth, thereby improving the quality and efficiency of product palletizing. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 , 2 As shown, a lifting platform includes a screw lifting mechanism 1, a stacking and conveying mechanism 2 on the screw lifting mechanism 1, and a gantry truss transplanting mechanism correspondingly above the screw lifting mechanism 1. The screw lifting mechanism 1 includes a lifting drive assembly, the output end of which is connected to a vertical screw 16. The stacking and conveying mechanism 2 includes a conveyor line frame 21 connected to the vertical screw 16, and a conveyor line 22 is provided inside the conveyor line frame 21. The gantry truss transplanting mechanism includes a graphite box gripping mechanism horizontal linear module 3 located above the vertical screw 16. A graphite box gripping mechanism longitudinal linear module 4 is fitted at the lower end of the horizontal linear module 3. The lower end of module 4 is connected to a dual-purpose box-removing and lid-adding clamping mechanism 5. The pallet fed by the pallet feeding mechanism is moved to the pallet conveying mechanism 2 via the screw lifting mechanism 1. The products on the box lifting and partitioning isolation mechanism are stacked in the pallet via the gantry truss transfer mechanism. The lifting and lowering adjustment of the pallet conveying mechanism 2 is driven by the screw lifting mechanism 1. When it descends, it cooperates with the pallet feeding mechanism to first send the pallet to the pallet conveying mechanism 2. When it rises, it moves with the gantry truss transfer mechanism to facilitate the robot to grab the graphite boxes containing the products and place them in the pallet for lifting and palletizing operations. This lifting linkage makes the palletizing operation simple and smooth, thereby improving the quality and efficiency of product palletizing.

[0017] like Figure 1As shown, in this embodiment, the lifting drive assembly includes a base 11, a lifting motor 12 is provided in the middle of the base 11, the output end of the lifting motor 12 is connected to a main drive seat 13, both ends of the main drive seat 13 are connected to driven drive seats 14, both ends of the driven drive seats 14 are connected to horizontal drive rods 15, the output end of the horizontal drive rods 15 is engaged with the vertical lead screw 16, and the palletizing conveyor 2 is connected to the middle of the vertical lead screw 16. The forward and reverse rotation of the lifting motor 12 drives the driven drive seats 14 to rotate simultaneously, causing the four vertical lead screws 16 to rotate, controlling the lifting and lowering movement of the conveyor frame 21 and the conveyor line 22. First, it moves to the position of the pallet feeding mechanism to move the pallet onto the conveyor line 22, and then moves to the position corresponding to the material box lifting partition isolation seat. Then, the gantry truss transfer mechanism moves to grab the loaded product into the pallet.

[0018] In this embodiment, the conveyor line frame 21 has an installation groove in the middle to facilitate the installation of the conveyor line 22. The conveyor line 22 includes a conveyor motor 23 on the conveyor line frame 21 and several transmission rollers in the installation groove. The transmission rollers are covered with a conveyor belt 24. The output end of the conveyor motor 23 is connected to the transmission rollers by a chain or belt. When the pallet is placed on the conveyor line 22, the conveyor line 22 is first moved to a position flush with the pallet conveyor rollers by the lifting drive assembly. The pallet conveyor rollers and the conveyor line 22 rotate together to move the pallet onto the conveyor line 22. In addition, after the pallet is finished, the conveyor line 22 sends out the palletized products together.

[0019] In this embodiment, the graphite box gripping mechanism's horizontal linear module 3 includes a support frame 31. Two horizontal support plates 32 are connected to the lower end of the support frame 31 via a slider. One end of one horizontal support plate 32 is equipped with a horizontal moving motor 33. A connecting rod 34 is provided between the two horizontal support plates 32. The output end of the horizontal moving motor 33 is connected to the horizontal support plate 32 via a horizontal drag chain. The graphite box gripping mechanism's vertical linear module 4 includes a vertical support plate 41 connected to the bottom of one end of the horizontal support plate 32. The vertical support plate 41 is equipped with a vertical moving motor 42. The output end of the vertical moving motor 42 is connected to a vertical drag chain. The bottom end of the vertical support plate 41 is slidably connected to the box-removing and lid-adding dual-purpose gripping mechanism 5. In use, the horizontal moving motor 33 drives the horizontal support plate 32 and the graphite box gripping mechanism's vertical linear module 4 to move together; while the vertical moving motor 42 drives the box-removing and lid-adding dual-purpose gripping mechanism 5 to move towards the graphite box containing the product and the tray on the conveyor line 22.

[0020] In this embodiment, the dual-purpose box-removing and lid-adding clamping mechanism 5 includes a connecting frame. The lower end of the connecting frame is connected to a graphite box gripping and lifting cylinder 51. The output end of the graphite box gripping and lifting cylinder 51 is horizontally provided with a graphite box gripping cylinder 52. The output end of the graphite box gripping cylinder 52 is connected to a gripper 53. When it moves above the graphite box containing the product, the graphite box gripping and lifting cylinder 51 drives the gripper 53 to move to the upper outer side of the graphite box. Then, the graphite box gripping cylinder 52 drives the gripper 53 to clamp the graphite box. Through the cooperation of the horizontal linear module 3 and the vertical linear module 4 of the graphite box gripping mechanism, the graphite box containing the product is sent to the pallet on the conveyor line 22 for stacking. After the stacking is completed, the dual-purpose box-removing and lid-adding clamping mechanism 5 adds a cover plate to the top layer for sealing.
