Description
Technical Field
The utility model relates to an active power filter production field especially relates to a heat dissipation silicone grease paints instrument.
Background
The active power filter inevitably generates heat due to the switching loss of the IGBT, and the heat is generally designed to be transferred from the IGBT through a heat sink, so in order to realize rapid heat transfer, a heat-conducting silicone grease is usually coated on the contact surface between the IGBT and the heat sink.
The conventional manual smearing mode cannot well control the consumption of silicone grease and the smearing thickness, so that a series of problems of heat dissipation, consumption and the like are caused; in the prior art, a partition plate with holes is covered on an IGBT (insulated gate bipolar translator) and is scraped once by a scraper, and grease points which are basically the same are distributed on the IGBT at intervals after the partition plate is taken up, like a silicone grease coating device of an IGBT module in a patent CN 201120400962.8; however, the method has low efficiency and inaccurate manual smearing, and the silicone grease needs to be put in firstly.
Therefore, a heat conduction silicone grease brushing device for a radiator is designed.

In order to achieve the above object, the utility model provides a following technical scheme: a heat-conducting silicone grease brushing device for a radiator comprises a workpiece table, a Z-axis lifting system, a Y-axis moving system, an X-axis moving system and a gluing mechanism; the gluing mechanism comprises an installation frame, a grease storage tank and an extrusion mechanism, the gluing mechanism is installed on a Y-axis moving system through the installation frame, the Y-axis moving system is installed on a Z-axis lifting system, and the workpiece table is installed on an X-axis moving system; the lower opening of the grease storage tank is connected with a greasing needle head, the greasing needle head is obliquely connected with a scraper plate which is lower than the greasing needle head, a pore plate which is relatively highly fixed with the scraper plate is arranged below the scraper plate, the pore plate is arranged on a support of a Y-axis moving system, and a plurality of elastic support columns are arranged on a workpiece platform.
Preferably, the extrusion mechanism comprises a motor screw driving mechanism, a screw nut plate and a push rod, the push rod is fixed below the screw nut plate and inserted into the grease storage tank, and the screw nut plate is mounted on the screw.
Further, the device also comprises a controller which controls the extrusion mechanism to continuously start or jog.
As a preferable mode, the workpiece table is provided with a plurality of grooves in which springs are installed, and the supporting columns are located in the grooves and connected with the springs to form elastic supporting columns.
Preferably, the Z-axis lifting system, the Y-axis moving system and the X-axis moving system all adopt motor lead screw driving mechanisms.
In addition, the orifice plate should not be too thick.
The utility model has the advantages that: high efficiency, accurate smearing position and difficult waste, and lays a foundation for full-automatic operation.
