Digital-bus-based automatic small-U-shaped-pipe inserting system of fin assembly

Abstract

The invention discloses a digital-bus-based automatic small-U-shaped-pipe inserting system of a fin assembly. The digital-bus-based automatic small-U-shaped-pipe inserting system comprises a mechanical arm (1), a mechanical hand (2), a bracket and small U-shaped pipe bearing tray assembly (3) capable of supplying small U-shaped pipes circularly and an electric control device (4). The mechanical arm is fixedly mounted on the ground and comprises an X-coordinate driving mechanism, a Y-coordinate driving mechanism and a Z-coordinate driving mechanism. The mechanical hand comprises a body (21), clamping fingers (22) and a supporting finger (23). The bracket and small U-shaped pipe bearing tray assembly capable of supplying the small U-shaped pipes circularly comprises a multilayer bracket (31), small U-shaped pipe bearing trays (32), a power device (33) and an electric control mechanism (34). The electric control mechanism comprises an industrial control computer, a power supply loop, a mode identification loop, a counting loop, a small U-shaped pipe grabbing loop, a pipe insertion control loop and the like. The digital-bus-based automatic small-U-shaped-pipe inserting system has the advantages that automatic operation can be achieved, influence of human factors on production progress is reduced, and quality of products obtained through pipe insertion processes can be guaranteed.

Description

technical field [0001] The invention relates to a fin assembly automatic intubation system, in particular to a digital bus-based automatic fin assembly small U-shaped tube insertion process suitable for radiator and condenser fin assembly intubation procedures of air conditioners. A pipe system belongs to the technical field of air-conditioning manufacturing. Background technique [0002] Usually, metal sheets with strong thermal conductivity are added on the surface of the heat exchange device that requires heat transfer to increase the heat exchange surface area of ​​the heat exchange device and improve the heat exchange efficiency. The metal sheets with this function are called fins. [0003] There are two main heat exchangers in the air conditioner, namely the radiator and the condenser. The working medium of these two heat exchangers is refrigerant on one side and air on the other side. In order to enhance the heat transfer of the heat exchanger, generally The heat exc...

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the manual intubation operation, human factors such as the operator's sense of responsibility and emotion have a greater impact on the production progress, and because the previous tube expansion process is carried out by the tube expander, the efficiency is high, so in order to meet the follow-up The normal operation of the drying and welding process often requires multiple people to perform the manual intubation process, and the labor intensity of the operators is high and the efficiency is low;

[0008] 2. Although the front tube expansion process and the subsequent drying and welding process have been automated, the intubation process is still manually operated. Therefore, due to unreasonable personnel arrangements, too much output is often accumulated in the front process and the subsequent process When the process is shut down and waiting for materials, the degree of automation of the equipment is low, the utilization rate of the equipment is low, and the production capacity cannot be guaranteed;

[0009] 3. Since the intubation process is manual, it requires high skills and proficiency of the operators. The uneven operation proficiency of multiple operators also affects the production progress to varying degrees, and easily leads to unstable product quality.
