Description

Technical Field

[0001] The utility model particularly relates to a feeding mechanism for processing flat workpieces. Background Art

[0002] The condenser is an indispensable component in 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 a coil that passes through the heat dissipation fins. There are gaps between adjacent heat dissipation fins. When working, one side of the finned condenser as a whole serves as the windward side facing the wind, and the other side serves as the air outlet side facing the fan. 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 the heat dissipation fins 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 tube wall and the heat dissipation fins. The airflow carries away the heat of the refrigerant, and the temperature of the refrigerant flowing out of the coil drops. The cooled refrigerant then enters the evaporator and returns to the compressor through the evaporator, 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, the traditional positioning method of processing equipment is 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.

[0028] As a preferred embodiment of the clamping assembly 2, Figure 2 and Figure 3 As shown, the clamping assembly 2 includes a clamping base 21, a first clamping plate 22 is provided on the clamping base 21, and a sliding clamp seat 23 is connected to the clamping base 21, which can slide relative to it and approach or move away from the first clamping plate 22.

[0030] As a preferred embodiment of the transport component 4, Figure 6 As shown, the transport assembly 4 includes a plurality of transport slides 41 slidably connected to the frame 1, and the transport slides 41 are provided with support plates 42 for supporting the bottom side of the flat workpiece. The frame 1 is provided with a fourth drive device 43 for pushing the transport slides 41 to slide.

In addition, the adjustment slide 5 is provided with a mounting bracket 52, and the positioning seat 33 is slidably connected to the mounting bracket 52, so that the mounting bracket 52 and the transport slide 41a can be adjusted synchronously to accommodate flat workpieces of different sizes.

[0031] As a preference, Figure 6 As shown, the transport assembly 4 includes at least two transport slides 41, and the positioning plate 31 is arranged between two of the transport slides 41, so that when the positioning plate 31 rises, the flat workpiece placed on the support plate 42 can be lifted, and when the positioning plate 31 descends, the flat workpiece on the positioning plate 31 can be placed on the support plate 42.

[0032] As a preference, Figure 2 and Figure 3 As shown, the clamping base 21 is rotatably connected to the frame 1, and the bending drive structure 6 is a fifth drive device 26 provided on the frame 1. When the clamping base 21 rotates a certain angle, the gap between the first clamping plate 22 and the second clamping plate 25 is located on the moving path of the support plate 42, which can make the flat workpiece parallel to the first clamping plate 22 and the second clamping plate 25 for easy clamping. After the first clamping plate 22 and the second clamping plate 25 clamp the flat workpiece, the clamping base 21 is driven to rotate by the fifth drive device 26 to bend the workpiece. At the same time, the support plate 42 plays a supporting role, thereby ensuring that the workpiece can be stably limited during bending. Preferably, an arc-shaped bending plate 28 is connected to one side of the first clamping plate 22. When the workpiece is bent, the workpiece is bent along the bending plate 28.

[0033] As a preference, Figure 5 As shown, the top of the positioning member 35 is provided with a pressing plate portion 351 extending toward the positioning plate 31. The pressing plate portion 351 can press the top side of the flat workpiece to improve the accuracy of the flat workpiece during transportation.

[0035] When the loading mechanism is working, the flat workpiece is placed on the positioning plate 31 by a robot or manually, and the edges on the other side of the flat workpiece are pushed to the right by the positioning plate 31 and the positioning member 35, so that the flat workpiece maintains an accurate position. 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 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.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention.
