Description

Technical Field

[0001] The utility model relates to the field of radiator assembly equipment, in particular to a radiator feeding system. Background Art

[0002] In order to increase the heat dissipation efficiency of the radiator, multiple heat sinks need to be stacked and assembled to improve the heat dissipation efficiency. The sheet is processed into a heat sink that meets the design requirements through shearing and stamping processes. At present, in order to save costs, the factory does not carry out the flatness detection process for the heat sink, which leads to inconsistent thickness or slight bending of the heat sink during the assembly and stacking process of the heat sink. At the same time, due to the use of semi-automatic methods combined with manual stacking, this method is difficult to achieve assembly line operation and cannot be seamlessly integrated with the upper and lower processes. Manual stacking of heat sinks is inefficient and cannot guarantee the stacking quality of each heat sink. The lack of flatness detection and manual stacking of heat sinks result in low dimensional accuracy of the stacked products, and the stacked products are locally uneven. During the stacking process, the precision error will accumulate, resulting in poor contact between the heat sinks or uneven heat transfer, which seriously affects the overall heat dissipation performance of the radiator. Therefore, in order to solve the above problems, a heat sink feeding system is needed. Utility Model Content

[0050] The principle of this utility model is as follows: The loading mechanism places the heat sink at the input end of the conveyor. The conveyor belt 3 drives the heat sink to the bottom of the cleaning assembly 4. The atomizer 15 sprays a detergent to neutralize residual oil onto the surface of the heat sink. The first regulating cylinder 14 is used to adjust the distance between the atomizer 15 and the heat sink surface to maximize the contact surface. The conveyor belt 3 then drives the neutralized heat sink toward the output end. The heat sink enters the drying assembly 5, where hot air evaporates the detergent and removes any residual oil. The conveyor belt 3 drives the dried heat sink into the flatness detection component 6, and the first lifting cylinder 8 drives the lifting plate 9 to move downward so that the limit pin contacts the conveyor belt 3. Then, the flatness detection component 6 uses multiple laser probes 12 to perform flatness detection to ensure that the laser dot array fully covers the heat sink. The laser probe 12 simultaneously scans the flat surface and records the height information of each area and sends it to the data processor. The data processor obtains the flatness of the entire heat sink by analyzing the data scanned by multiple laser probes 12, and obtains the average surface height, the size and position information of the raised or recessed parts. The conveyor belt then drives the inspected heat sink through the screening component. When the flatness of the heat sink does not meet the requirements, the screening cylinder 16 drives the screening rod 17 to move along the width direction of the conveyor belt 3. The screening rod 17 pushes the defective heat sink from the conveyor belt 3, and the conveyor belt moves the qualified heat sink to the output end of the conveyor belt 3. Then, the first lifting rod 20 drives the grabbing mechanism down, so that the grabbing mechanism grabs the qualified heat sink, and the first lifting rod 20 drives the grabbing mechanism up. Then, the first rotating seat 19 drives the first lifting rod 20 to rotate, and the grabbing mechanism places the heat sink in the stacking area.

[0051] A stacking area is formed between the stacking bracket 26 and the two sets of adjustment assemblies. Depending on the size of the heat sink, the two second adjustment cylinders 27 each drive the corresponding limit assemblies 28 to move, adjusting the width of the stacking area. This process continues until the grasping mechanism places the heat sinks sequentially within the stacking area to form a heat sink group. Next, the two second adjustment cylinders 27 each drive the corresponding limit assemblies 28 to move, causing the limit blocks 32 to engage on either side of the heat sink group. The second lifting cylinder 31 is used to push the lifting block 30 up and down along the guide groove, causing the limit blocks 32 to press the pressing plate 33 against the upper end surface of the heat sink group. Next, the drive motor 34 drives the transmission shaft 36 to rotate, causing the stacking mechanism to flip the heat sink group downward and place it on the conveyor fixture of the next process. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiment described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
