[0024] The following is a detailed description of a radiator riveting device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 As shown, an embodiment of the utility model provides a heat sink riveting device, comprising: a workbench 1; a support frame 6, which is arranged on the top of the workbench 1, and the support frame 6 is in an inverted L shape, for supporting the riveting equipment; a rivet head 4, which is arranged on the support frame 6, for riveting the heat sink; a suction and exhaust part 5, which is arranged on the upper part of the rivet head 4, for eliminating the air between the rivet head 4 and the surface of the heat sink; and the rivet head 4 is connected to the bottom of the suction and exhaust part 5.

[0026] By providing the suction and exhaust part 5, dust on the surface of the heat sink can be cleaned before riveting. During the riveting process, the air between the rivet head 4 and the heat sink is absorbed, so that the surface of the heat sink and the rivet head 4 are in close contact, thereby reducing the occurrence of undesirable situations such as false riveting and missed riveting, and improving the riveting effect.

[0027] like Figure 1 and Figure 3As shown, the suction and exhaust portion 5 includes: a placement frame 51, which is fixed to one side of the support frame 6, and one side of the placement frame 51 is fixed to one side of the rivet head 4, for placing the rivet head 4; an absorber 52, which is arranged in the placement frame 51, for sucking and exhausting gas; a plurality of ventilation holes 53, which are respectively opened on both sides of the placement frame 51, and the plurality of ventilation holes 53 are staggered or evenly arranged for gas circulation.

[0028] By providing the vent hole 53, the gas can be discharged or inhaled during the operation of the absorber 52, so that the absorber 52 can operate normally, thereby improving its use effect; by providing the absorber 52, it can be configured as a small centrifugal fan or a small vacuum pump, etc., which can absorb and discharge the air. Before the processing process, the surface of the radiator is cleaned first to keep the surface of the radiator clean. After the processing process, the air between the radiator and the rivet head 4 can be absorbed to make them fit tightly, thereby improving the riveting effect.

[0029] like Figure 3 As shown, one side surface of the placing frame 51 is concave inwardly at the center of the placing frame 51 and has an arc-shaped structure.

[0030] By setting up the placement frame 51, the absorber 52 can be placed and stored to avoid collision or bumping due to external factors, thereby preventing the absorber 52 from being damaged and improving its protection performance. At the same time, the left and right sides of the bottom of the placement frame 51 are set to be inwardly concave and arc-shaped, so as to improve the gas circulation efficiency during the gas absorption process.

[0031] like Figure 1 As shown, the cylinder 7 is arranged on the top of the support frame 6, and the output end of the cylinder 7 passes through the support frame 6 and is connected to the suction and discharge part 5, which is used for lifting and lowering the riveting head 4.

[0032] By setting the support frame 6, it can be made of metal material, such as copper or iron, which has good firmness and is not easy to cause damage. At the same time, it can support the cylinder 7 to facilitate subsequent riveting.

[0033] like Figure 1 and Figure 2 As shown, a placement turn plate 3 is rotatably arranged on the top of the workbench 1 for placing the radiator; a placement slot 10 is arranged at the center of the top of the workbench 1; a stepper motor 11 is arranged in the placement slot 10, and the output end of the stepper motor 11 is connected to the placement turn plate 3 for providing power for the rotation of the placement turn plate 3; a plurality of clamping parts 9 are arranged on the top of the placement turn plate 3 for fixing the radiator.

[0034] By setting up a placement rotating plate 3, multiple clamping parts 9 can be placed, so that multiple heat sinks can be placed, and then through the cooperation of the stepping motor 11, the heat sink after riveting is detached from the riveting head 4, and a new heat sink is moved under the riveting head 4, so that the riveting process can be continuously performed to improve the riveting efficiency.

[0035] like Figure 1 and Figure 4 As shown, the clamping part 9 includes: a clamping frame 91, which is arranged on the placement rotating plate 3 and is used to provide a placement position for the radiator; a small motor 93, which is arranged on one side of the clamping frame 91 and is used to provide power for clamping the radiator; a two-way threaded rod 92, which is arranged in the clamping frame 91, and one side of the two-way threaded rod 92 extends to the outside of the clamping frame 91 and is connected to the output end of the small motor 93, and the threads of the two-way threaded rod 92 are opposite to each other, which is used for two-way movement of the radiator; a sliding plate 94, which is slidably arranged in the clamping frame 91 and is threadedly sleeved with the two-way threaded rod 92 to drive the radiator to move; two clamping plates 95, which are slidably arranged on the top of the clamping frame 91, and the bottoms of the two clamping plates 95 are connected to the sliding plate 94, and the two clamping plates 95 are L-shaped and correspondingly arranged to clamp the radiator.

[0036] The clamping plate 95 is provided to ensure the stability of the heat sink during the processing. The L-shaped clamping plate 95 can provide stable support and fixation for the heat sink, preventing the heat sink from moving or deforming during the riveting process, thereby ensuring accurate docking between the riveted part and the base material.

The stepper motor 11 rotates to drive the placement rotating plate 3 to rotate, so that the radiator is located under the rivet head 4. The cylinder 7 extends to drive the suction and discharge part 5 and the rivet head 4 to move downward. At the same time, the control panel 2 is used to start the absorber 52 to run, first discharge the radiator and clean the surface of the radiator. When the rivet head 4 is running, it is sucked to avoid air between the radiator and the rivet head 4, thereby improving the rivet effect. After the rivet is completed, the new radiator is moved under the rivet head 4 through the cooperation of the stepper motor 11 and the placement rotating plate 3. At the same time, the radiator after the rivet is completed passes through the optical sensor 8 for inspection. If the inspection is qualified, it is displayed by the display light.
