Description

Technical Field

[0001] The utility model relates to the technical field of lead frame production, in particular to a lead frame core material surface cleaning and drying machine. Background Art

[0002] Lead frames are an important basic material for making various semiconductor devices. They are mainly formed by stamping copper coils. During the production cycle, there will be oil stains and metal debris residues on the surface of the lead frame, so it needs to be cleaned after stamping.

[0003] In the related art, to address the existing cleaning method of placing multiple lead frames in a cleaning basket and then placing the cleaning basket in a cleaning solution for cleaning, this method often causes the lead frames to stack during cleaning, resulting in incomplete cleaning of the contacting surfaces of the lead frames and poor cleaning effect. In addition, after cleaning, they need to be manually arranged on a conveyor line for transportation, resulting in low production efficiency. Patent publication number CN221694535U provides a lead frame cleaning device. The lead frame cleaning device comprises at least one pair of mutually parallel guide rods provided on the circumferential outer wall of a rotating frame, and strip grooves are formed on the opposing side walls of the guide rods for transferring the lead frames. The side walls of the strip grooves are each provided with a clamping member for clamping the lead frames in the strip grooves. A drive belt is extended from the outlet end of the feed track and the inlet end of the discharge track toward the middle of the cleaning tank, and the rotating frame passes between the two guide rods. This can improve the cleaning effect and efficiency of the lead frames.

[0004] However, the existing lead frame is easy to clean after cleaning to avoid water stains. However, during use, the lead frame is easily adhered to dust, resulting in secondary contamination of the lead frame, thereby causing poor circuit transmission effect of the lead frame. Utility Model Content

[0005] The purpose of the utility model is to provide a lead frame core material surface cleaning and drying machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lead frame core material surface cleaning and drying machine, comprising a drying cylinder, a mounting base and a mounting box, an air outlet fixedly installed on one side of the drying cylinder, a door panel movably installed on the front end of the drying cylinder, an air inlet pipe extending to the drying cylinder fixedly installed on the top of the drying cylinder, a mounting base fixedly installed on the bottom of the air inlet pipe, a diversion pipe fixedly installed on the bottom of the mounting base, a mounting bracket fixedly installed on the outside of the diversion pipe, an electric telescopic rod fixedly installed on the bottom of the mounting bracket, a drying port fixedly installed on the outside of the diversion pipe, a mounting box slidably installed inside the drying cylinder, and a placement box slidably installed inside the mounting box.

[0007] Preferably, a support column is fixedly installed on the bottom of the drying drum, the drying drum and the door panel are movably installed through a rotating shaft, and a protective net is fixedly installed on the air outlet.

[0008] Preferably, the diversion pipe is connected to the drying port via a connecting pipe, and the connecting pipe is connected to the drying port via a bellows.

[0009] Preferably, the output end of the electric telescopic rod is fixedly connected to the outer side of the drying opening, and the installation box is located between the drying openings.

[0010] Preferably, the electric telescopic rod is fixedly installed between the drying port, and the mounting frame is provided with a sliding groove that cooperates with the sliding block.

[0011] Preferably, a filter is provided on the outside of the installation box, and a ventilation net is provided on the outside of the placement box.

[0012] In summary, this application has the following beneficial technical effects:

[0013] The utility model places the lead frame to be dried inside the placement box, slides the placement box to the inner side of the installation box, and places the installation box inside the drying cylinder. Dry air can be introduced into the interior through the air inlet pipe, and the introduced air can be guided to the drying port on both sides through the diverter pipe. The drying port is used to lift and spray the dry air to dry the installation box and the placement box. At the same time, the sliding block can be driven to slide downward by the telescopic action of the electric telescopic rod, and the sliding block can slide along the inner side of the sliding groove, so that the drying port can be conveniently moved up and down, thereby evenly drying the lead frame.
