Description

Technical Field

[0001] This invention relates to the field of packaging machinery and equipment technology, specifically to a robot for stacking and palletizing fragile materials. Background Technology

[0002] Fragile materials such as glass and tiles need to be stacked during storage and transportation so that they can be placed on pallets in the required order for easy forklift transport. Currently, most fragile material stacking is done manually, which is labor-intensive and inefficient, and easily leads to tipping and breakage of fragile materials during handling. To achieve fast and efficient stacking of fragile materials, existing manufacturers often use stacking mechanisms. These mechanisms mainly consist of a frame, suction cups, pallets, and guide rails. The suction cups hold the fragile materials in place, and the guide rails move the suction cups along the pallet. The stacking and translating process involves lifting, lowering, and translating the fragile materials to achieve stacking. However, this stacking and translating structure is complex and cumbersome to use. In actual use, because the fragile materials need to be lifted and translated, relying solely on suction cups for fixation can easily lead to insecure fixation. Furthermore, the need to lift, lower, and translating the fragile materials results in low stacking efficiency, making it difficult to meet the needs of large-scale production. Moreover, after the fragile materials are stacked on the pallet, the lower layer is inconvenient to unload, causing inconvenience. Therefore, to solve the problems that arise during the actual stacking of fragile materials, a fragile material stacking robot is needed to achieve fast and efficient stacking and translating of fragile materials. Summary of the Invention

[0015] Beneficial effects

[0016] This invention provides a robot for palletizing and stacking fragile materials. Compared with existing technologies, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. This fragile material palletizing and stacking robot has a first electric telescopic rod fixedly installed on a support frame. The first electric telescopic rod drives a suction cup device to lift and pick up fragile materials conveyed on a conveyor belt. The support frame can move horizontally via a horizontal moving mechanism, thereby driving the suction cup device to move horizontally, and then palletizing and stacking the fragile materials. By setting a second electric telescopic rod on the support frame, the second electric telescopic rod can drive an L-shaped limiting plate to move horizontally. At the same time, the first lifting mechanism can drive the second electric telescopic rod to move up and down, thereby driving the L-shaped limiting plate to move up and down. Thus, after the fragile materials are picked up, the L-shaped limiting plate moves to both ends of the fragile materials to provide lateral limiting support, thereby avoiding the risk of the fragile materials falling during transportation due to the suction cup device not being firmly attached, and improving the safety of fragile material transportation.

[0019] 2. This fragile material palletizing and stacking robot features a bracket above a pallet, on which a pallet for stacking fragile materials is mounted. The pallet can rotate via a rotating rod, and the bracket can be raised and lowered via a first drive mechanism, thereby raising and lowering the pallet. When fragile materials are lifted and moved horizontally above the pallet, the lifting and lowering of the pallet reduces the distance the materials travel after being lifted. This reduces the risk of fragile materials falling during transport and improves the stacking efficiency of fragile materials through the coordinated lifting and lowering of the pallet, meeting the needs of large-scale palletizing and stacking. Furthermore, the lifting and lowering of the pallet facilitates manual handling and unloading of the stacked fragile materials.

[0020] 3. This fragile material palletizing and stacking robot uses a buffer assembly between the second electric telescopic rod and the L-shaped limiting plate. The buffer assembly includes a fixed block, a damping groove, a damping block, and a spring shock absorber. When the fragile material is laterally clamped and fixed by the L-shaped limiting plate, the damping block and damping groove absorb the energy of sliding friction to absorb the vibration energy during the movement of the fragile material, and the shock absorption performance of the spring shock absorber effectively improves the stability of the L-shaped limiting plate when limiting the fragile material, thereby improving the stability of the fragile material during transportation. In addition, the limiting plate fixedly installed on the top of the pallet can limit the fragile material on both sides after it is stacked to prevent it from slipping during transportation. At the same time, the rubber plate on the limiting plate has elasticity to increase the anti-collision performance of the fragile material after it is stacked and transported.

The rotating rod 19 is driven to rotate by a first driving mechanism 20. The first driving mechanism 20 includes a first driven gear 201 fixedly installed on the rotating rod 19. A first driving gear 202 is connected to one side of the first driven gear 201 via gear transmission. The first driving gear 202 is fixedly installed on the output shaft of a third motor 203. The third motor 203 drives the first driving gear 202 to rotate.

The third threaded sleeve 214 moves horizontally due to the thread transmission between it and the bidirectional threaded rod 211, thereby moving the hinge rod 215 and lifting the bracket 15, causing the bracket 15 to rise or fall.

[0038] In use, this fragile material palletizing and stacking robot has a first electric telescopic rod 6 fixedly installed on the support 5. The first electric telescopic rod 6 drives the suction cup device 8 to lift and pick up the fragile material 3 conveyed on the conveyor belt 4. The support 5 can move horizontally via the horizontal moving mechanism 13, thereby driving the suction cup device 8 to move horizontally, and then the fragile material 3 is conveyed and placed on the pallet 16 for palletizing and stacking. By setting a second electric telescopic rod 9 on the support 5, the second electric telescopic rod 9 can drive the L-shaped limiting plate 10 to move horizontally. At the same time, the first lifting mechanism 12 can drive the second electric telescopic rod 9 to move up and down, thereby driving the L-shaped limiting plate 10 to move up and down. Thus, after the fragile material 3 is sucked up, it can be moved to both ends of the fragile material 3 by the L-shaped limiting plate 10 to provide lateral limiting support for the fragile material 3, thereby avoiding the risk of the fragile material 3 falling during transportation due to the suction cup device 8 not being firmly attached, and improving the safety of the fragile material 3 during transportation; in addition, the present invention provides a bracket 15 above the tray 14, and the bracket 15 is provided with a tray 16 for stacking the fragile material 3. The tray 16 can be rotated by the rotating rod 19, and the bracket 15 can be driven to rise and fall by the first driving mechanism 20, which in turn can drive the tray 16 to rise and fall, so that the fragile material 3 can be horizontally moved to the tray after being sucked up. When the pallet 16 moves upward and downward, it can reduce the movement distance of the fragile material 3 after it is picked up. This reduces the risk of the fragile material 3 falling during transportation and improves the stacking efficiency of the fragile material 3 by moving the pallet 16 in conjunction with the lifting movement, meeting the needs of large-scale stacking. At the same time, the pallet 16 can be raised and lowered, making it convenient for manual handling and unloading of the fragile material 3 after stacking. In addition, the present invention sets a buffer assembly 11 between the second electric telescopic rod 9 and the L-shaped limiting plate 10. The buffer assembly 11 includes a fixed block 111, a damping groove 112, a damping block 113, and spring shock absorbers 114 and 115. Then, when the L-shaped limiting plate is moved upward and downward, the buffer assembly 11 can reduce the movement distance of the fragile material 3 after being picked up. When the plate 10 clamps and fixes the fragile material 3 laterally, the damping block 113 and the damping groove 112 damping sliding friction energy dissipation absorb the vibration energy during the movement of the fragile material 3, and the shock absorption performance of the spring shock absorber 114 effectively improves the stability of the L-shaped limiting plate 10 when limiting the fragile material 3, thereby improving the stability of the fragile material 3 during transportation. In addition, the limiting plate 17 fixedly installed on the top of the pallet 16 can limit the sides of the fragile material 3 after stacking to prevent the fragile material 3 from slipping during transportation. At the same time, the rubber plate 18 set on the limiting plate 17 has elasticity to increase the anti-collision performance of the fragile material 3 during transportation after stacking.
