Description

1 TARIFF FOR COPPER AND ALUMINUM SURFACES IN ELECTRICAL BUSBARS PARAMETER-CONTROLLED DUAL-STATION HIGH-SPEED LASER CLEANING MACHINE TECHNICAL FIELD The invention relates to the application of paint / coating processes to certain surfaces of electrical busbars. It relates to a laser cleaning device developed for restoring conductivity. STATE OF THE ART 10 An electrical busbar is a device that collects electrical energy of the same voltage and frequency and provides a safe environment. It is a thick metal rod or strip that distributes the heat to different circuits. It is usually made of copper. They are also made of aluminum. They are commonly used in electrical panels, transformers, and power plants. They are used to carry high current. When electrical busbars are manufactured, they are coated with paint or It is completely covered with insulation material. However, for the electrical transmission of the busbar, the job is 15 these paint or insulation points, called tongues, where it connects to the area It needs to be cleaned of its material. On the tabs of the electrical busbars. to safely clean any paint or insulation coating found industrial gel paint remover chemicals or delicate mechanical scraping methods It is used. To avoid damaging the busbar surface and reducing conductivity, scraping is done at 20°C. The process must be carried out carefully. Both chemical and scraping methods... It takes considerable time and requires precision. Another technique used for cleaning the tongue of electrical busbars is traditional laser. In surface treatment systems, only one surface of the workpiece can be machined, the bottom surface 25 The part needs to be rotated for processing. This increases the processing time. It prolongs the process and leads to loss of sensitivity. Positioned opposite each other. In laser heads, the high-power laser beam is reflected back at a perpendicular angle (back- Surface reflection causes serious damage to optical components and galvo heads. Cleaning and roughening processes are carried out as separate operations. These 30 This situation extends the coating preparation time and also makes the quality control process two-stage. This requires immediate monitoring of surface quality after the process. 2 Because it could not be done properly, inadequately cleaned or roughened areas were overlooked. They are able to escape. DEFINITION OF INVENTION The present invention aims to eliminate the aforementioned disadvantages and the related technical aspects. It relates to a device developed to bring new advantages to the field. The primary purpose of this invention is to process the upper and lower surfaces of the bar tongue simultaneously. to reduce the time by half, the busbar section according to galvanometric laser heads by positioning it at an angle, the high-power laser beam is reflected back off the optical component, and 10 To prevent damage to the heads, the directional mirrors inside the switch box. via a single line both cleaning and sandblasting / roughening power supply between cleaning laser power unit and roughening laser power units facilitating the transition, closed-loop camera-based image processing system (loop) by performing quality control and only local laser re-applying to the missing areas. 15 to apply and clean the area of ​​the workpiece to be coated, in that order. A laser is used to apply roughening processes to prepare the material for coating. The goal is to create the device.
