Description

Technical Field

[0001] The invention relates to the technical field of production of air conditioner outdoor units, and in particular to a conveying mechanism for producing air conditioner outdoor units. Background Art

[0002] With the development of science and technology, the improvement of people's living standards, the gradual popularization of home appliances such as air conditioners have become necessities in life, which in turn promotes the mass production of air conditioners. In the past, production operations were all manually assembled and tested, but manual assembly operations are prone to human defects such as missed assembly and missed testing. More importantly, the low production efficiency is far from meeting the needs of mass production. With the development of automation technology, it has become a necessary requirement for enterprises to replace manpower with machinery and equipment to adapt to the development of the times and improve production efficiency.

[0003] Refrigerant is the medium of refrigeration equipment, which is used for heat exchange of fluid (air) medium to produce cooling effect. After being compressed by the compressor, the temperature of the refrigerant rises. When passing through the pipeline system, the heat is blown away by the cooling fan and enters the outside air. When it continues to circulate, the refrigerant expands and absorbs heat, and the indoor air is cooled. The refrigerant circulates continuously along the closed-loop pipeline, absorbing heat from the room and releasing it to the outdoor air, and the indoor temperature continues to decrease. When the set temperature is reached, the compressor stops working in standby mode. Since the refrigerant must circulate in a closed pipeline, no leakage is allowed in the pipeline system.

[0004] During the production process of air conditioners, they need to be leak-checked to avoid refrigerant leakage. Currently, the refrigerant leak detection of air conditioners is performed manually during the manual assembly process without sealing, which is prone to quality anomalies such as missed detection and incomplete detection.

After the product is sealed, the cache transplanter 17 lifts and transports the sealed product away from the double-speed chain conveyor line 6 and enters the box body sealed cache component 5 for cyclic cache movement until 25 air conditioners are cached and sealed for 5 minutes. Then, it is transferred to the double-speed chain conveyor line 6 again through the leak detection feeding conveyor line 9 and the leak detection transplanter 16, and enters the leak detection room 1. The product enters the leak detection room 1 and is positioned. The leak detection component 11 extends into the detection box 3 for automatic leak detection. After the detection is completed, the data is uploaded for analysis to determine whether the product is leaking refrigerant. At the same time, the gun head is automatically retracted. The air conditioner outdoor unit is retracted and returned to its original position, and the air conditioner outdoor unit is released to flow into the next process. After the air conditioner outdoor unit product leaves the leak detection room 1, it flows under the box collecting mechanical arm assembly 13. The box collecting blocker 18 rises to stop the air conditioner outdoor unit product and positions it. The box collecting mechanical arm assembly 13 takes the detection box 3 on the product and transports it to the hollow replacement conveyor belt 15. The air is replaced by the hollow replacement conveyor belt 15 and transported to the box covering mechanical arm assembly 2 area for buffering and circulation. The products with OK test results continue to flow to the next process; the products with NG test results are transferred to the repair conveyor line 14 for manual processing. The motion control program of the entire equipment completes the refrigerant leak detection material during the transportation of the air conditioner outdoor unit. 37 empty boxes are placed and cached in the top box storage belt line group 4 to ensure that the cycle does not wait. 25 boxes are cached in the lower box body sealing cache assembly 5. Each box body has a sealing time of 5 minutes. Leakage detection is performed on the 26th box. The detection time of each air conditioner outdoor unit is shortened to 12 seconds, thereby improving the overall efficiency of the production line and reducing labor costs, and minimizing the probability of unqualified products leaving the factory.
