Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a heat sink stacking clamp. Background Art

[0002] In order to increase the surface heat dissipation efficiency of the radiator, multiple heat sinks need to be stacked and assembled during production to improve the heat dissipation efficiency. During the processing, the sheet needs to undergo shearing and stamping processes to be processed into heat sinks that meet the design requirements. At present, in order to save costs, the factory mainly adopts a semi-automatic method combined with manual stacking. This method is difficult to achieve assembly line operation and cannot be seamlessly integrated with the upper and lower processes. At the same time, manual stacking of heat sinks is time-consuming and labor-intensive, and inefficient. Manual operation is difficult to meet production capacity requirements, and the stacking quality of each heat sink cannot be guaranteed. Accuracy errors will accumulate during the stacking process. Therefore, in order to solve the above problems, a heat sink stacking fixture is needed. Utility Model Content
