Online automatic U pipe inserting system

Abstract

The invention discloses an online automatic U pipe inserting system. The online automatic U pipe inserting system comprises a screening and shaping mechanism used for screening and shaping short U pipes, an online positioning mechanism used for positioning and adjusting an air conditioner condenser, and an automatic clamping claw floating mechanism used for inserting the short U pipes into the air conditioner condenser. The initial position of the automatic clamping claw floating mechanism corresponds to the travel terminal of the screening and shaping mechanism, and the ending position of the automatic clamping claw floating mechanism corresponds to the travel terminal of the online positioning mechanism. According to the online automatic U pipe inserting system, the consistency of the short U pipes is improved through the screening and shaping mechanism, and automatic insertion of the short U pipes is facilitated; the online positioning mechanism is provided with an adjusting component and a horizontal limiting portion to carry out pose adjustment on workpieces before clamping and locating of the workpieces, so that the positions of the clamped workpieces meet the positioning requirement of U pipe inserting assembling, and the U pipe inserting precision is improved; the automatic clamping claw floating mechanism is used for automatically inserting the short U pipes into the air conditioner condenser.

Description

technical field [0001] The invention relates to the field of automatic assembly of short U pipes of air-conditioning condensing pipes, in particular to an online automatic U pipe insertion system. Background technique [0002] At present, the known automatic assembly of air conditioner condensers and evaporators is completed offline. The air conditioner condensers and evaporators are transported to designated locations through the line body, and then the air conditioner condensers and evaporators are grabbed from the line body by robots and put into assembly. In the assembly station, the cylinder is used for clamping and positioning, and the short U tube is inserted. After the short U tube is inserted, the robot is used to re-place the air conditioner condenser and evaporator on the line body and transport it to the next One station. This offline working method needs to use robots to take out and put the air conditioner condenser and evaporator back into the line body, whic...

AI Technical Summary

Problems solved by technology

This offline working method needs to use robots to take out and put the air conditioner condenser and evaporator back into the line body, which increases the assembly time and lowers the assembly efficiency. In addition, the air cylinder is used to directly clamp and position the air conditioner condenser and evaporator. In the actual working process, since the poses of the air conditioner condenser and evaporator on the line body cannot be exactly the same, the pose of the condenser when the robot grabs the air conditioner condenser and evaporator and places it in the assembly station cannot be completely the same. Similarly, this method of direct clamping and positioning using the cylinder tends to tilt the air conditioner condenser and evaporator, and the clamping accuracy is difficult to meet the working accuracy requirements of the subsequent short U tube insertion, while improving the accuracy of the short U tube insertion process. Short U tube consistency requirements

[0003] Especially for multiple jaws installed side by side in the short U insertion process at the same time, the positioning accuracy of the condensing fins and the consistency of the short U are more demanding, but in the actual production process, the consistency of the short U is not very good. Even if the positioning accuracy is improved, it is difficult to insert the short U into the condensing fin smoothly. The current method of determining the insertion depth of the short U through the given downward movement distance of the robot is prone to short U during the insertion process. The case of being stuck in the middle makes it impossible to achieve the insertion depth

[0004] At the same time, because the height of the welding ring of the short U-tube is inconsistent with the center distance of the nozzle, some short U-tubes lack a welding ring, and some short U-tubes need a certain amount of external force to insert them into the long U-tube of the air-conditioning condenser. The air conditioner condenser is unqualified, and the existing manual assembly cannot meet the requirements of automatic production
