Description

Technical Field

[0001] This invention relates to the field of loading and unloading robot technology, specifically to a loading and unloading robot for wood-plastic composite boards. Background Technology

[0002] As an environmentally friendly and durable new composite material, wood-plastic composite board is increasingly widely used in building decoration, logistics packaging, and landscaping. With the surge in downstream market demand, wood-plastic composite board production is gradually transforming towards large-scale and automated production. As a key connecting process in the production process, the efficiency and stability of loading and unloading directly determine the capacity and product quality of the entire production line. Currently, there are still many technical bottlenecks in the loading and unloading of wood-plastic composite boards and subsequent auxiliary processing, which restrict the process of industrial upgrading. Traditional wood-plastic composite board loading and unloading operations mainly rely on manual labor or simple equipment, which has significant drawbacks: the wood-plastic composite boards to be processed need to be manually carried to the feeding end of the processing equipment, and then manually stacked after processing. The weight of a single wood-plastic composite board can reach tens of kilograms, and long-term handling leads to high labor intensity for workers; at the same time, manual transfer of boards one by one is slow and difficult to keep up with the high-speed production rhythm of the processing equipment, which can easily cause a break in the connection between processes. Wood-plastic composite boards often have problems such as burrs and rough surfaces after cutting. Specialized sanding equipment is required, and the boards are manually transferred to the sanding station and then back to the stacking area. This multi-stage transfer not only increases labor costs but also easily causes secondary damage to the boards. Summary of the Invention

[0046] Working principle and usage process of this invention: S1. Conveying unit 400 conveys the wood-plastic composite board with processing and feeding to the position of the robot arm, waiting for retrieval; During this period, after the active conveyor rail 401 is started, it drives the conveyor block 402 to move linearly. Simultaneously, the carrier plate 403 fixed on the conveyor block 402 will carry the pallet 404 on top for conveying. At this time, the wood-plastic board stack waiting to be loaded on the pallet 404 will reach the position of the switching unit 300. Start the rotating cylinder 301 to rotate and adjust the top component, causing the plug plate 302 to switch to the state corresponding to the tray 404. Start the telescopic cylinder 303 to retract the connecting block 306 to insert the plug plate 302 into the second plug interface of the tray 404. Then start the telescopic cylinder 304 to raise the lifting block 307, causing the tray 404 connected to the plug plate 302 to be lifted. Then use the rotation of the rotating cylinder 301 to transfer the tray 404 to the placement seat 201. At this time, the tray 404 has become the second tray 202. S2, the drive unit 100 will adjust itself in real time, and the component structure at the drive end will enter the extraction state; During this process, the joint drive between the support arm 103 and the active lifting arm 104, the lifting adjustment of the active lifting arm 104, and the joint drive between the active flipping arm 105 and the active lifting arm 104 are used to adjust the material support plate 700 above the tray 202 and ensure that the material support plate 700 is in a flipped-down state. At this time, the clamping plate 601 is located below the material support plate 700. Then, the material support plate 700 is lowered to make the wood-plastic composite board stack located between the clamping plates 601. Then, the telescopic cylinder 3 602 is activated to drive the sliding plate 603, causing the clamping plates 601 to retract and clamp the wood-plastic composite board at the top of the wood-plastic composite board stack. The thickness of the clamping is consistent with the height of the clamping plate 601. During clamping, the mounting shell 817 is lifted and retracted into the n-shaped plate 812. Then, with the cooperation of the overall structure of the drive unit 100, the clamped wood-plastic board is extracted and switched, causing the clamped wood-plastic board to switch from the bottom to the top of the support plate 700. Then rotate the conveyor assembly to position 500 for loading; S3. The clamping plate 601 disengages from the clamping state and adjusts itself to a position close to the receiving roller 504; At this point, simply drive the telescopic cylinder 826. The telescopic cylinder 826 retracts itself to drive the bracket 827 to descend. At that time, the assembly plate 822 will descend synchronously, causing the suction cup 823 at its bottom to align and adsorb the wood-plastic composite board on the material support plate 700. Then, start the motor at the shaft end of the drive spindle 811 to cause it to flip outward within the active flipping ear 604. In this way, through the combined effect of the grinding component 810 and the extraction component 820, the adsorbed wood-plastic composite board is flipped synchronously. Since there is a clearance between the receiving rollers 504, the grinding component 810 and the extraction component 820 enter the clearance, and the adsorbed wood-plastic composite board will be placed on the receiving rollers 504. During the flipping, the mounting shell 817 has been lowered to the working state to avoid interference with the receiving rollers 504. The above describes the material loading process; S4. When the robotic arm is loading materials; The main feeding frame 501 will push the processed wood-plastic board onto the receiving roller 504 through the guide roller 503. Then, the adsorption component will be adjusted to be below the pushed wood-plastic board in advance by flipping. Then, it will be adsorbed and extracted by flipping and placed on the top surface of the support plate 700. This stacking is carried out in this way. When the stacking reaches the clamping height of the clamping plate 601, the extraction will stop. If a cut surface appears on one or both sides of the wood-plastic composite board, the motor on the drive gear 814 is activated to drive the toothed plate 815, causing the toothed plate 815 to move the mounting shell 817 at the bottom to adjust its height, so that the mounting shell 817 is adjusted to the middle position of the stacked wood-plastic composite boards; the telescopic cylinder three 602 is activated to retract the clamping plate 601, so that the grinding surface of the active grinding disc 816 is in contact with the cut surface of the wood-plastic composite board; then the telescopic cylinder five 829 is activated to drive the bottom plate 821 to descend as a whole, at which time the pressing port 824 will press down to the top surface of the stacked wood-plastic composite boards. The purpose of this is to press and fix the wood-plastic composite boards to prevent them from shifting during subsequent operations; Finally, the motor on the active grinding disc 816 can be started to rotate and grind the cut surface of the wood-plastic composite board. At the same time, the active lead screw 818 in the mounting housing 817 is driven by the motor and uses its own guide to drive the active grinding disc 816 to move linearly, so as to make the active grinding disc 816 move and grind the surface of the wood-plastic composite board. Once completed, the items can be placed, stacked, and transported in accordance with the methods described in S1 and S2.
