[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It's typically made of aluminum alloy, brass, or bronze in the form of plates, sheets, or multiple sheets. For example, a computer's CPU uses a fairly large heat sink, as do the power and line transistors in televisions and the power amplifier tubes in amplifiers. Generally, a layer of thermally conductive silicone grease is applied to the contact surface between the electronic component and the heat sink to more effectively conduct heat from the component to the heat sink, where it is then dissipated into the surrounding air.

[0022] Through the cooperation of the arc plate 7 and the arc groove 8, when the device is in use, the height position of the movable rod 10 can be adjusted inside the arc groove 8, thereby adjusting the height position of the upper pressure roller 9, and then adjusting the distance between the upper pressure roller 9 and the roller 18, so that the device can load and convey heat sink sheets 5 of different thicknesses, which is convenient for the use of the device. When the heat sink sheet 5 needs to be replaced, the movable rod 10 can be placed at the end position inside the arc groove 8 to prevent the upper pressure roller 9 from squeezing the heat sink sheet 5 and affecting the removal of the heat sink sheet 5.

[0023] The interior of the upper pressure roller 9 is provided with an upper pressure roller inner groove 14, one end of the movable rod 10 is slidably inserted into the interior of the upper pressure roller inner groove 14, and the outer surface of the movable rod 10 located inside the upper pressure roller inner groove 14 is movably installed with a compression spring 15.

[0024] Through the cooperation of the compression spring 15 and the movable rod 10, when the device adjusts the distance between the two support frames 3, the distance between the arc plates 7 on both sides will be adjusted together with the support frames 3. At this time, the compression spring 15 will push the limit block 11 to move to the inner side of the upper pressure roller inner groove 14, so that the movable rod 10 and the limit block 11 move together with the support frame 3, thereby preventing the upper pressure roller 9 from falling off from between the arc plates 7 on both sides.

[0025] Four fixed sleeves 12 are movably installed on the outer surface of the fixed rod 6, and a rotating rod 13 is slidably installed on the side of the fixed sleeve 12 close to the heat sink plate 5. A cross expansion groove 20 is provided inside the fixed sleeve 12, and a cross slider 22 is fixedly installed on the outer surface of the rotating rod 13. The cross slider 22 is slidably inserted into the inside of the cross expansion groove 20.

[0026] Through the cooperation between the fixed sleeve 12 and the rotating rod 13, when the device is in use, the rotating rod 13 can be pulled out from the inside of the fixed sleeve 12 by pulling the rotating rod 13, thereby adjusting the position of the roller 18, and then the device can load and convey heat sink sheets 5 of different widths, making the use of the device convenient.

[0027] A servo motor 17 is provided on the inner side of the cross expansion slot 20 , and the output end of the servo motor 17 is connected to the rotating shaft 19 through a coupling. A rotating shaft slot 23 is provided on one inner end of the rotating rod 13 , and the rotating shaft 19 is slidably inserted into the interior of the rotating shaft slot 23 .

[0028] A straight plate 24 is fixedly installed inside the rotating shaft slide 23, and a straight groove 21 is provided on the outer surface of the rotating shaft 19. The straight plate 24 is slidably inserted into the straight groove 21. The other end of the rotating rod 13 is fixedly installed with a roller 18. The top end of the heat sink sheet 5 is in contact with the bottom end surface of the upper pressure roller 9, and the bottom end of the heat sink sheet 5 is in contact with the surface of the roller 18.

[0029] Two sliding grooves 2 are provided on the top surface of the bottom plate 1, and the bottom ends of the support frames 3 are slidably inserted into the sliding grooves 2. The surfaces of the support frames 3 are fixedly mounted with plug-in shafts 16, which are movably inserted into the two ends of the barrel 4.

[0030] Through the cooperation of the sliding groove 2 and the support frame 3, when the device is in use, the support frame 3 can be moved along the direction of the sliding groove 2 to adjust the distance between the two support frames 3, so that the device can install barrels 4 of different sizes, making the use of the device convenient.

[0031] When the auxiliary feeding mechanism for heat sink riveting processing is used, the support frame 3 is first moved along the direction of the sliding groove 2 to adjust the distance between the two support frames 3 so that the device can install barrels 4 of different sizes.

[0032] Then, the heat sink sheet 5 passes through the position between the upper pressing roller 9 and the roller 18. At this time, the servo motor 17 is started to drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating rod 13 to rotate at the same time due to the insertion of the straight plate 24 into the straight groove 21, thereby driving the roller 18 to rotate, so that the roller 18 pushes the heat sink sheet 5 to move, thereby realizing the loading of the heat sink sheet 5;

[0033] When feeding the heat sink sheet 5, the rotating rod 13 can be pulled out from the inside of the fixed sleeve 12 to adjust the position of the roller 18, so that the device can feed and transport heat sink sheets 5 of different widths, which is convenient for use of the device.

[0034] When loading the heat sink sheet 5, the height position of the movable rod 10 can be adjusted inside the arc groove 8 to adjust the height position of the upper pressing roller 9, and then the distance between the upper pressing roller 9 and the roller 18 can be adjusted, so that the device can load and convey heat sink sheets 5 of different thicknesses, which is convenient for the use of the device. When the heat sink sheet 5 needs to be replaced, the movable rod 10 can be placed at the end position inside the arc groove 8 to make the upper pressing roller 9 suspended in the air to prevent the upper pressing roller 9 from squeezing the heat sink sheet 5 and affecting the removal of the heat sink sheet 5.
