Description

Technical Field

[0001] The invention particularly relates to a loading mechanism of flat workpiece processing equipment. Background Art

[0002] The condenser is an indispensable part of the air conditioning compression refrigeration system. It is generally equipped with a fan. The finned condenser is a commonly used condenser structure. It consists of multiple rows of heat dissipation fins and coils that penetrate the heat dissipation fins. There are gaps between adjacent heat dissipation fins. When working, one side of the finned condenser as a whole faces the wind as the windward side, and the other side faces the fan as the air outlet side. The high-temperature refrigerant output by the compressor enters the condenser. The fan works at the same time to pump air to form an airflow. The airflow passes through the gaps between each heat dissipation fin from the windward side of the finned condenser, then enters the fan from the air outlet side, and is finally sent out from the fan. In this process, the high-temperature refrigerant forms heat exchange with the airflow through the coil wall and the heat dissipation fins. The heat of the refrigerant is taken away by the airflow, so the temperature of the refrigerant flowing out of the coil drops. The refrigerant with a lowered temperature enters the evaporator again, passes through the evaporator and returns to the compressor, completing the refrigerant cycle. Traditional condenser fins are generally flat, but some condenser fins need to be processed into a curved shape, such as the condenser fin structure with patent number CN202321079637.5 and the name of a patented solution for a condenser. However, for the processing of condenser fins that need to be bent, traditional processing equipment positioning methods are difficult to ensure the precise position of the flat workpiece during the processing process, and it is difficult to ensure the stable position during the transportation process. The transportation efficiency is low, and the transportation method reduces the work efficiency of the entire production line.

Then the positioning plate 31 descends, so that the flat workpiece is placed on the support plate 42, and the transport slide 41 slides to the right and then transports the flat workpiece to between the first clamping plate 22 and the second clamping plate 25. After the first clamping plate 22 and the second clamping plate 25 clamp the flat workpiece, the clamping base 21 rotates a certain angle, and under the support of the support plate 42, the workpiece is bent along the bending plate 28 so that the flat workpiece is bent and formed, and then the flat workpiece is processed. After the processing is completed, the clamping base 21 is reset, and the first clamping plate 22 and the second clamping plate 25 release the workpiece, so that the flat workpiece is placed back on the support plate 42, and the transport slide 41 slides to the left and then transports the processed flat workpiece back to the loading position.
