[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets, or multiple sheets. Some existing electronic products, such as smart chargers, have high requirements for internal heat dissipation, and often require the power transistor components to be directly locked onto the heat sink to dissipate heat.

[0003] Publication No. CN220637828U discloses a fixture for processing heat sinks. A lifting mechanism is arranged below the fixture platform, and a cam is used to drive the lifting platform to reciprocate up and down, so that an ejector pin ejects the processed heat sink in the positioning groove through an ejection hole at the bottom of the positioning groove, thereby improving the efficiency of removing the heat sink and not easily causing damage to transistor components. The tension spring and pull rod structure can easily control the rotation of the cam and adjust the speed of the ejector pin ejecting the heat sink, making the operation more flexible. However, the following problems still exist in the actual use of this patent:

[0004] Although the jig for processing the heat sink drives the lifting platform to reciprocate up and down by the cam so that the ejector pin ejects the processed heat sink in the positioning groove through the ejection hole at the bottom of the positioning groove, thereby improving the efficiency of removing the heat sink, the position of the heat sink in the positioning groove is not limited, and the heat sink is prone to shaking when processing, thereby affecting the production of the heat sink.

[0005] The invention provides an aluminum heat sink processing jig provided with a material pressing member, so as to solve the above-mentioned problems. Utility Model Content
