Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, and in particular to a power module side frame cleaning device. Background Technology

[0002] With the growing global demand for efficient and reliable power conversion and control, power modules, as core components of power electronic systems, are becoming increasingly important. By integrating advanced power semiconductor devices, they enable efficient power conversion and management, and are therefore widely used in many key fields, such as aerospace, communications technology, medical equipment, automotive manufacturing, and home appliances.

[0003] In the existing technology, the entire packaging process of power modules can be roughly divided into the following steps: (1) First, the chip is loaded, precision surface mount, soldering and fixing, bonding wire connection (connecting the chip to the substrate or lead frame), and pin installation are carried out to ensure the electrical connection between the components; (2) The substrate and side frame are assembled to form the basic structure of the module and provide mechanical support and heat dissipation path; (3) Then, potting and curing are carried out, that is, special packaging materials are used to fill the inside of the module to protect the internal components, and the packaging materials are hardened through the curing process to enhance the integrity and protection performance of the module; (4) Finally, the top cover is assembled to complete the packaging of the entire module and ensure that it has good sealing and mechanical strength.

[0004] In the aforementioned packaging process, during side frame assembly of the substrate, adhesive needs to be applied to the edges of the side frames before they are pressed together with the substrate edges. This requires the side frame edges to maintain a certain level of cleanliness during adhesive application. However, during production, due to various reasons, the side frame edges are prone to contamination (for example, to achieve product barcode traceability, marking is generally required on the side frames before assembly, and dust is easily generated and adheres to the side frame edges during marking). This can lead to abnormal adhesive application, resulting in substandard bonding between the substrate and the side frame, affecting product yield. Existing equipment mainly relies on dust covers to avoid contamination at the side frame edges during side frame assembly. However, dust covers cannot prevent contamination during transport or clean contamination already caused by previous processes, thus offering limited protection against contamination and failing to completely solve the problem. Utility Model Content

[0005] This utility model provides a power module side frame cleaning device, which can clean the edges of the side frame before applying adhesive, reducing adhesive application abnormalities and improving product yield. The specific technical solution is as follows:

[0029] First Embodiment

[0030] like Figure 3 , Figure 4 As shown, the power module side frame cleaning device includes a side frame carrier 3, a transmission component 4, a cleaning component 5, and an adjustment component 6. Specifically:

[0031] The side frame carrier 3 can be used to stably support the side frame 1. For example, the side frame 1 can be stably placed on the side frame carrier 3 by means of limiting components, pressure blocks, clamps, etc.

[0032] The transmission component 4 can be used to transport the side frame carrier 3, so that the side frame carrier 3 moves to the cleaning station. The transmission component 4 can be a component such as a conveyor belt.

[0033] The cleaning component 5 is located at the cleaning station, above the transmission component 4, and can be used to clean dirt and dust on the inner edge 11 of the side frame 1.

[0034] The adjustment component 6 is connected to the cleaning component 5 and can drive the cleaning component 5 to move laterally or longitudinally, or more preferably, to move both laterally and longitudinally at the same time. In this patent, the lateral movement refers to forward and backward movement, left and right movement, or simultaneous forward, backward and left and right movement.

[0035] In this embodiment, the adjustment component 6 includes a lateral moving component 61 and a longitudinal moving component 62. Specifically, the cleaning component 5 is movably connected to the longitudinal moving component 62, and the cleaning component 5 can move up and down under the drive of the longitudinal moving component 62. The longitudinal moving component 62 is movably connected to the lateral moving component 61, and the lateral moving component 61 is fixedly installed on the power module side frame cleaning device by a bracket. Under the drive of the lateral moving component 61, the longitudinal moving component 62 can move laterally, thereby enabling the cleaning component 5 to also move laterally.

[0036] The power module side frame cleaning device with the above structure, through the cooperation of the side frame carrier 3, the transmission component 4, the cleaning component 5 and the adjustment component 6, can clean the inner edge 11 of the side frame 1 before applying glue, and clean the dirt and dust on the inner edge 11 of the side frame 1 from all directions. The operation is flexible and convenient, which can reduce glue application abnormalities, make the bonding effect between the side frame 1 and the substrate 2 better, and improve the product yield.

[0037] In some embodiments, the transmission component 4 is also provided with a sensor (not shown in the figure). The sensor can detect the position of the side frame carrier 3. When the side frame carrier 3 moves into the cleaning station, it sends a feedback signal and then controls the control system to stop the side frame carrier 3 from moving and stay in the cleaning station for cleaning.

[0038] The power module side frame cleaning device with the above structure can accurately position the side frame carrier 3 through the setting of the sensor, making the power module side frame cleaning device more stable and reliable, thereby improving the cleaning effect.

[0039] In some embodiments, the transmission component 4 includes a transverse guide rail 41, and the side frame carrier 3 is slidably mounted on the guide rail 41. In this embodiment, the guide rail 41 is a double guide rail configuration, which is more stable and reliable. The side frame carrier 3 can be directly slidably mounted on the guide rail 41 via a slider, or it can be directly slidably mounted on the guide rail 41. No limitation is made here.

[0040] The power module side frame cleaning device with the above structure achieves the transmission and movement of the side frame carrier 3 by sliding it on the guide rail 41, which is more stable and reliable.

[0041] In some embodiments, the top of the side frame carrier 3 is provided with a limiting groove adapted to the side frame 1. When the side frame 1 is placed on the side frame carrier 3, the side frame carrier 3 can directly limit the side frame 1 laterally, thereby achieving stable load bearing. This not only has a simple structure and low cost, but also has good load bearing effect and is stable and reliable.

[0042] In some embodiments, the cleaning component 5 is a plasma cleaning head, which is a non-contact cleaning method. It can effectively decompose and remove organic pollutants, grease, oxides and fine particles on the side frame 1 through the interaction between plasma and the material surface, and the cleaning effect is better than traditional cleaning methods.

[0043] In some embodiments, a dust cover is also provided on top of the cleaning component 5, and a dust suction component is provided inside the dust cover, so as to effectively collect and process the cleaned material and further improve the cleanliness.

[0049] The cleaning component 5 is located at the cleaning station, above the transmission component 4, and can be used to clean dirt and dust on the inner edge 11 of the side frame 1.

[0050] The adjustment component 6 is connected to the cleaning component 5 and can drive the cleaning component 5 to move laterally or longitudinally, or more preferably, to move both laterally and longitudinally at the same time.

[0051] In this embodiment, the adjustment component 6 includes a joint connector 63 disposed on the end of the cleaning component 5 away from the cleaning head. The joint connector 63 may be a universal joint, a ball joint, or other components, which can drive the cleaning head of the cleaning component 5 to rotate and swing, thereby enabling the cleaning component 5 to move in the lateral and longitudinal directions.

[0052] In some embodiments, the adjustment component 6 further includes a longitudinal moving component 62, which is fixedly mounted on the power module side frame cleaning device.
