Unordered automatic pipe grabbing and inserting manipulator for small U-shaped pipes of fin assembly

Abstract

The invention discloses an unordered automatic pipe grabbing and inserting manipulator for small U-shaped pipes of a fin assembly. The unordered automatic pipe grabbing and inserting manipulator comprises a body (1), two clamping fingers (2) and two lifting fingers (3), the top end of the body is connected with the tail end of a mechanical arm (4) through a mounting seat (11), a C coordinate rotating mechanism is arranged in the mounting seat, arc-shaped grooves I (11) and arc-shaped grooves II (21) matched with outer diameter and U-shaped radian size of the small U-shaped pipes are formed in the bottom end face of the body and the inner side faces of the clamping fingers respectively, a position sensor and a distance sensor are arranged on the body, the clamping fingers and the lifting fingers are arranged in a mutually perpendicular manner and connected with a transmission connection mechanism respectively, and distance size from the upper surface of the finger end of each lifting finger to the groove bottom of the corresponding arc-shaped groove I is matched with diameter size of each small U-shaped pipe. The unordered automatic pipe grabbing and inserting manipulator can realize automated operation, influence, on production progress, of human factors can be lowered, and product quality in the pipe inserting process can be guaranteed.

Description

technical field [0001] The invention relates to a fin assembly automatic grasping and intubation manipulator, in particular to an automatic grasping of the small U-shaped tubes of the fin assembly in the process of inserting the fin assembly of the radiator and condenser of the air conditioner without order. A pipe intubation manipulator belongs to the technical field of air conditioner 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 ...

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.
