Description

Technical Field

[0001] The utility model relates to the field of heat sink detection equipment, in particular to a flatness detection device. Background Art

[0002] In the process of traditional heat sink assembly and stacking, there are many heat sinks in the heat sink. Since the flatness detection process is not carried out for the heat sinks, it is easy to have inconsistent thickness or slight bending of the heat sinks. Therefore, during the stacking process of the heat sinks, the stacked products will be uneven locally, resulting in the accumulation of precision errors in the radiator. At the same time, the lack of flatness detection will lead to low dimensional accuracy of the stacked products. Especially when stacking multiple layers of heat sinks, poor contact or uneven heat transfer between the heat sinks will affect the overall heat dissipation performance of the radiator. Therefore, in order to solve the above problems, a flatness detection device is needed. Content of the Utility Model

Then the conveyor belt drives the detected heat sinks through the screening component.

The conveyor belt moves the qualified heat sinks to the output end of the conveyor belt 2.
