At the second calibration station, the lower pressure plate 72 moves toward the top plate 33 inside the U-shaped plate 340, so that the heat dissipation base plate 11 is against the top of the heat dissipation U-shaped plug 12, thereby realizing the vertical limitation of the heat dissipation base plate 11, ensuring the vertical position accuracy of the heat dissipation base plate 11, improving the quality and consistency of subsequent riveting, reducing the product defective rate, and further improving production efficiency and product quality.

[0056] The defective product conveyor belt 93 and the good product conveyor belt 94 are respectively arranged on both sides of the fourth robot 91.

[0057] Reference Figure 2 , Figure 3 and Figure 4In the embodiment of the present application, the fourth manipulator 91 can automatically grab the riveted products and classify them according to the results of the visual inspection device 92 and place them on the defective conveyor belt 93 or the good conveyor belt 94, thereby achieving effective distinction and efficient processing of product quality.

[0058] The implementation principle of the riveting system of a heat sink 1 in the embodiment of the present application is: When the fixture 3 passes through the insert feeding station, the first vibration plate 41 is used to automatically arrange and convey the heat dissipation U-shaped insert 12, thereby improving the stability and accuracy of the heat dissipation U-shaped insert 12 feeding. The first manipulator 42 is responsible for accurately placing the heat dissipation U-shaped insert 12 arranged by the first vibration plate 41 to the specified position in the fixture 3. After the heat dissipation U-shaped insert 12 clamps the first vertical plate 341 and the corresponding second vertical plate 342, the first side plate of the heat dissipation U-shaped insert 12 is inserted into the first limiting hole 3301, and the second side plate is inserted into the second limiting hole 3302, thereby limiting the horizontal position of the heat dissipation U-shaped insert 12.

[0059] When the fixture 3 passes through the base plate loading station, the second vibration plate 51 is used to automatically arrange and transport the heat dissipation base plate 11, thereby improving the stability and accuracy of the heat dissipation base plate 11 loading. The second manipulator 52 is responsible for accurately placing the heat dissipation base plate 11 arranged by the second vibration plate 51 at the designated position in the fixture 3. The second manipulator 52 places the heat dissipation base plate 11 horizontally in the U-shaped plate 340. Under the positioning effect of the U-shaped plate 340, the card slot 1101 on the heat dissipation base plate 11 can be exactly positioned with the heat dissipation U-shaped plug 12, and then the heat dissipation bottom is moved down so that the upper end of the heat dissipation U-shaped plug 12 is inserted into the card slot 1101, thereby realizing the plug-in connection between the heat dissipation base plate 11 and the heat dissipation U-shaped plug 12.

[0060] When the fixture 3 passes through the first calibration station, the side pressure plate 62 moves toward the U-shaped plate 340 and presses the heat dissipation base plate 11 into the bottom of the U-shaped groove of the U-shaped plate 340 to achieve horizontal limitation of the heat dissipation base plate 11 and ensure the horizontal position accuracy of the heat dissipation base plate 11.

[0061] When the fixture 3 passes through the second calibration station, the lower pressure plate 72 moves toward the top plate 33 inside the U-shaped plate 340, so that the heat dissipation base plate 11 is against the top of the heat dissipation U-shaped insert 12, thereby realizing the vertical limit of the heat dissipation base plate 11 and ensuring the vertical position accuracy of the heat dissipation base plate 11.

[0062] When the fixture 3 passes through the riveting station, the third vibration plate 81 automatically arranges and transports the rivets 13, and the third manipulator 82 carries the arranged rivets 13 to the first rivet hole 1102 of the heat dissipation base plate 11, and vertically inserts the rivet 13 into the first rivet hole 1102 and the second rivet hole 1201, preliminarily defining the relative position of the rivet 13, the heat dissipation base plate 11, and the heat dissipation U-shaped insert 12. Then the lower pressing block 83 moves downward to press the upper end of the rivet 13, and the upper pressing block 84 moves upward to press the lower end of the rivet 13, thereby deforming the rivet 13 and riveting the heat dissipation base plate 11 and the heat dissipation U-shaped insert 12 together.

[0063] When the clamp 3 passes the unloading station, the fourth manipulator 91 can automatically grab the riveted products and classify them according to the results of the visual inspection instrument 92 and place them on the defective product conveyor belt 93 or the good product conveyor belt 94, thereby achieving effective distinction and efficient processing of product quality.
