[0002] MOS transistors are important semiconductor devices widely used in electronic circuits, particularly in digital and analog circuits. Their key features include high input impedance, low on-resistance, and fast switching speed, giving them significant advantages in amplification and switching circuits. MOS transistors generate significant heat during operation, especially high-power MOS transistors. Therefore, using a heat sink can effectively prevent damage caused by overheating.

Even the same MOS tube model can require different numbers of MOS tubes installed on heat sinks of different sizes depending on the circuits used. It's also possible to install multiple MOS tubes of different models on the same heat sink. Although the assembly steps are simple and can be manually installed one by one, it still requires significant manpower and material resources, and is time-consuming and labor-intensive.

[0050] A1. Accept assembly requirements in real time, including radiator specification information, at least one MOS tube specification information, and assembly drawing information;

[0051] A2. Matching and Generating an Assembly Plan: Generate an assembly plan based on assembly requirement information using a pre-set assembly control model. The assembly plan includes assembly process information and equipment parameter information. The assembly control model is a machine learning model that is iteratively trained using historical assembly data.

[0052] A3. Parameter setting: The assembly controller 7 sends the equipment parameter information to the radiator conveyor belt 1, silicone grease dripping assembly 2, MOS tube conveying module 3, material collection assembly module 4, material collection assembly 5, and packaging and storage module 6 for parameter setting;

Through these steps, the assembly control model intelligently determines and generates an assembly plan based on assembly requirements, achieving intelligent and automated assembly of MOS tubes and heat sinks. This approach has excellent universality and effectively improves the universality and efficiency of MOS tube assembly.

[0055] Reference Figure 7 In step A5, control instructions are generated based on the assembly process information to control the heat sink conveyor belt 1, the silicone grease dripping assembly 2, the MOS tube conveying module 3, the material taking assembly module 4, the material taking assembly 5, and the packaging and storage module 6 to assemble and package the heat sink MOS tube according to the assembly process. The specific steps include:

[0056] B1. Loading: Generate control instructions based on assembly process information, control the MOS tube pitch-changing module 321 to adjust the spacing of the MOS tube conveyor belt 31, and start the radiator conveyor belt 1 and multiple MOS tube conveyor belts 31 to convey the radiator and MOS tubes;

[0057] B2. Dripping silicone grease: According to the control instruction, the silicone grease dripping component 2 is controlled to drip a specified amount of silicone grease into the installation groove of the radiator;

[0058] B3. Retrieving and Installation: Control the variable pitch assembly module 43 to adjust the spacing of the multiple retrieving assembly assemblies 44 according to the control instructions, and control the two sets of multi-axis linear modules 41 to drive the multiple retrieving assembly assemblies 44 to remove the MOS tubes from the multiple MOS tube conveyor belts 31 through the suction air pipes 441. Then, control the two sets of multi-axis linear modules 41 to drive the multiple retrieving assembly assemblies 44 to install the multiple MOS tubes in the installation slots of the radiator, and control the electric screw machine 442 to screw the MOS tubes and the radiator together.

[0059] B4. Unloading: After the screws are fixed, the distance between the multiple sets of pneumatic grippers 52 is adjusted by the control command of the material picking and changing module 54. The multiple telescopic driving members 55 drive the multiple sets of pneumatic grippers 52 to grab the assembled radiator.

[0060] B5.

Multiple telescopic drive parts 55 drive the multiple groups of pneumatic grippers 52 to synchronously place the grabbed radiators into various packaging boxes.

[0061] In addition, the above step B3 does not have to be completed in a single time. When there are too many MOS tubes installed on the radiator and they are distributed in multiple rows or the spacing between the MOS tubes is very small (which rarely happens because the heat dissipation performance of the MOS tubes cannot be guaranteed), batch installation can also be performed. However, timely batch installation can still greatly improve the assembly efficiency of the MOS tube and the radiator compared to the existing single installation or manual installation. The embodiment of the present application discloses a MOS tube assembly device.
