Description

Technical Field

[0001] The utility model belongs to the technical field of oil removal equipment, and in particular relates to an oil removal device used for pre-treatment of plastic parts during electroplating. Background Art

[0002] In the electroplating industry, the workpiece needs to be pre-treated before electroplating. The purpose of pre-treatment is to remove dust, grease, rust, dirt and other impurities attached to the surface of the workpiece, so as to increase the adhesion of the metal coating during electroplating and improve the surface quality of the coating. If the grease on the surface of the part is not cleaned during the pre-treatment process, it will seriously affect the adhesion of the coating on the workpiece surface.

[0003] After searching, the patent announcement number CN213061054U discloses a degreasing device used for parts pre-plating treatment, including a box body, the inner cavity of the box body is provided with a cleaning tank, the lower part of the inner cavity of the cleaning tank is slidably connected to a placement plate through a slide groove, the placement plate is provided with a plurality of through holes, an ultrasonic generator is fixedly installed on the right side of the inner cavity of the cleaning tank and located at the lower part of the placement plate, an air outlet nozzle is embedded in the top of the cleaning tank, a temperature and humidity sensor is embedded in the top of the right side of the inner cavity of the cleaning tank, and a pump is fixedly installed on the upper part of the left side of the box body. The utility model solves the problem that the existing degreasing device for parts pre-plating treatment has poor degreasing effect and does not have a drying function, which is inconvenient for people to use, through the cooperation of the sewage outlet, pump, fan, heating box, overflow pipe, heating block, cleaning tank, placement plate, ultrasonic generator, battery and air outlet nozzle.

[0004] In actual use, the existing degreasing device for electroplating pretreatment generally uses water to rinse the grease on the plastic parts, or places the plastic parts in liquid for immersion degreasing. The above degreasing method not only consumes a large amount of water resources, but also has poor degreasing effect, and a certain amount of grease will remain on the plastic parts. For this reason, we propose a degreasing device for plastic parts pretreatment of electroplating to solve the existing problems. Utility Model Content
