Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial robots, and in particular to a robotic loosening tool for detecting valves of an air conditioning unit. Background Technology
[0002] The two valves on the outdoor unit of an air conditioner are a high-pressure valve and a low-pressure valve. Their main functions are to control the flow of refrigerant, regulate the rate at which the refrigerant absorbs and releases heat, and control the refrigerant during the installation, disassembly, and maintenance of the air conditioner to prevent leakage.
[0003] Air conditioner refrigerants achieve cooling and heating effects by absorbing and releasing heat. The high and low pressure valves on the outdoor unit control the rate at which the refrigerant absorbs and releases heat, thus affecting the air conditioner's cooling or heating efficiency. Lower pressure accelerates heat absorption, while higher pressure accelerates heat release.
[0004] After the outdoor unit of the air conditioner is assembled and installed in the factory, it needs to be tested. This includes assembling and testing the high-pressure and low-pressure valves, and charging it with refrigerant. After this is completed, the test valve connectors need to be removed and then reused. Currently, all disassembly operations are done manually, which is inefficient and delays the production cycle.
