Board surface cleaning equipment for printed circuit board

Abstract

The invention discloses board surface cleaning equipment for a printed circuit board, and relates to the technical field of cleaning equipment. The board surface cleaning equipment comprises a mounting frame, a conveying mechanism, a cleaning mechanism, a drying mechanism, a cooling recycle mechanism, a fixing mechanism and a heating mechanism, wherein the conveying mechanism is arranged at the lower end of the inner side of the mounting frame, the cleaning mechanism is arranged above one side of the conveying mechanism, and meanwhile the drying mechanism is arranged above the other side of the conveying mechanism; a cleaning box is arranged on one side of the cleaning mechanism, and the fixing mechanism is placed on the conveying mechanism; and the heating mechanism is fixedly installed on the vertical inner side wall, on one side of the drying mechanism, of the mounting frame. According to the board surface cleaning equipment for the printed circuit board, through the fixing mechanism, the conveying mechanism, the cleaning mechanism, the drying mechanism, the heating mechanism and the cooling recycle mechanism which are sequentially composed, automatic and efficient cleaning of the circuit board can be achieved, damage to the circuit board during cleaning is avoided, the circuit board can be dried through inert gas in a clean and closed environment, and dust pollution and oxygen oxidation are avoided.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, in particular to a board surface cleaning equipment for printed circuit boards, which is mainly used for cleaning printed circuit boards. Background technique [0002] The circuit board, also known as the PCB board, is mainly used for the centralized installation and connection of electrical components, which improves the integration of electrical components. There will be some solder traces and dust on the circuit board after the electrical components are installed, which need to be cleaned , the existing cleaning devices for printed circuit boards are mainly cleaned by brushes, which can easily lead to breakage of the connecting circuit of electrical components, so the hardness of the brushes is too high, and the board surface is not clean.

[0002] The circuit board, also known as the PCB board, is mainly used for the centralized installation and connection of electrical components, which improves the integration of electrical components. There will be some solder traces and dust on the circuit board after the electrical components are installed, which need to be cleaned , the existing cleaning devices for printed circuit boards are mainly cleaned by brushes, which can easily lead to breakage of the connecting circuit of electrical components, so the hardness of the brushes is too high, and the board surface is not clean. Some printed circuit board cleaning devices are also equipped with drying devices to facilitate timely drying of printed circuit boards after cleaning, but the existing drying devices mainly heat the air directly, and the dust in the air is easy to adhere to On the board surface, and oxygen is easy to oxidize the circuit board at high temperature, which affects the quality of the circuit board

[0003] Existing public document, CN208450079U-a kind of printed circuit board cleaning device, discloses that its structure includes support, control cabinet, control button, power supply interface, conveyer belt, cleaning chamber, cooling hole, motor, water pump and drain outlet, the utility model A printed circuit board cleaning device is provided with a water tank, a water pipe, a filter, a water pump and a drain on the right side of the bracket, so that water can be recycled and reused, and the sewage containing impurities flowing out of the cleaning room is filtered by the filter inside the filter After the effect, impurities can be filtered out, and the water can be recycled and reused after being pumped by the water pump, which solves the disadvantage that the cleaning water cannot be recycled and causes the waste of water resources. A drying device is installed on the right side of the cleaning room, and t
