Description

Technical Field

[0001] This utility model relates to the field of electronic component processing, and in particular to a baking fixture for powder coating of electronic components. Background Technology

[0002] Electronic components are the building blocks of electronic parts and small machines and instruments. They are often composed of several parts and can be used interchangeably in similar products. They commonly refer to certain parts in the electrical, radio, and instrument industries, and are a general term for electronic devices such as capacitors, transistors, hairsprings, and mainsprings. Common examples include diodes.

[0003] A Chinese authorized patent (publication number: CN215766166U) discloses a baking fixture for powder coating of electronic components. The fixture further secures the electronic components by inserting the leads of the electronic components into a fixing part and attracting and fixing the leads of the electronic components with magnets. The fixing part is made of foam or floral foam, which allows the leads of the electronic components to pass through the fixing part and not fall off, making it easy to pick up and put down the electronic components.

[0004] However, the aforementioned patents suffer from uneven airflow distribution, which can easily lead to localized overheating, causing damage to electronic components and reducing the yield rate. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A baking fixture for powder coating of electronic components, including a mounting plate;

[0007] A heat pipe is provided at the lower end of the mounting plate, and a base plate is provided at the lower end of the heat pipe. Multiple heat-conducting through holes are provided on the side wall of the heat pipe.

[0008] Multiple fasteners for clamping electronic components are stacked on the outer side of the heat pipe. Each fastener has multiple heat-conducting grooves on the side near the heat pipe. Each heat-conducting groove has an upper inclined groove and a lower inclined groove on the other side. The heat-conducting through hole forms a heat flow channel with the heat-conducting groove, the upper inclined groove, and the lower inclined groove.

[0009] The upper end of the mounting plate is provided with multiple fastening screws. The threaded end of each fastening screw passes downward through the mounting plate and contacts the uppermost fixing component.

[0010] As a further embodiment of this utility model: each fixing member is provided with a high-temperature resistant elastic clamping member on its upper and lower sides, and the elastic clamping member is made of either silicone or polytetrafluoroethylene.

[0011] As a further embodiment of this utility model, anti-slip textures are provided on the outer side of the elastic clamping member.

[0012] As a further embodiment of this utility model: a connecting flange is provided at the upper end of the heat pipe, and the heat pipe is connected to an external heat source through the connecting flange; a solenoid valve is provided at the lower end of the heat pipe.

[0013] As a further embodiment of this utility model: the upper end of the mounting plate is provided with a plurality of connecting hooks for connecting with external lifting devices.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the pins of electronic components between two adjacent fixing parts, the fastening screws can make the contact between the adjacent fixing parts tighter, thereby clamping the electronic components more stably. The stacked fixing parts can bake multiple electronic components at the same time. The heat flow enters the heat conduction groove through the heat conduction holes on the heat conduction pipe, and then flows outward through the upper and lower inclined guide grooves, so that the heat flow forms a laminar flow from the surface of the electronic components, uniformly covering the surface of the electronic components, avoiding local overheating or airflow dead zones, and achieving uniform baking of the surface of the electronic components.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
