Description

Technical Field

[0001] This utility model relates to the technical field of PCB board cleaning devices, and in particular to a PCB board vacuum brush cleaning device. Background Technology

[0002] During the manufacturing process, most surfaces of PCB substrates easily generate and attract static electricity, turning the PCB substrate surface into a high magnetic field. This attracts dust particles from the surrounding environment, affecting the quality of the PCB substrate or hindering the processing of subsequent processes. Therefore, cleaning devices are needed to remove impurities and dust adhering to the board surface during PCB production.

[0003] Currently, existing PCB cleaning devices on the market, such as the structure disclosed in publication number CN210022937U, use a conveyor belt with a cleaning brush roller and a negative pressure cleaning hood directly above it. The cleaning brush removes dust and impurities adhering to the PCB, and the negative pressure cleaning hood absorbs and recovers the brushed-off dust and dirt, thus completing the cleaning of the upper and lower surfaces of the PCB. However, on the one hand, the existing structure can only clean one side of the PCB at a time, requiring two cleaning cycles to clean both sides of the PCB, resulting in poor cleaning efficiency. On the other hand, when the cleaning brush roller rotates to clean the PCB surface, some of the dust removed moves to the sides of the cleaning brush roller, preventing some dust and impurities from being absorbed by the negative pressure cleaning hood, thus affecting the cleaning effect of the PCB. Therefore, improvements are necessary. Utility Model Content

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. By setting a V-shaped feed negative pressure adsorption conveyor line and a complementary discharge negative pressure adsorption conveyor line on the base, and setting a vacuum cleaning brush assembly between the feed negative pressure adsorption conveyor line and the discharge negative pressure adsorption conveyor line, one end of which extends to the middle of the feed negative pressure adsorption conveyor line and the other end extends obliquely to the side of the feed negative pressure adsorption conveyor line, the PCB board enters from the feed negative pressure adsorption conveyor line and passes through the vacuum cleaning brush assembly, thereby achieving simultaneous dust cleaning of both sides of the PCB board, which greatly improves the cleaning efficiency. At the same time, since the vacuum cleaning brush assembly is obliquely set and the vacuum cleaning brush assembly is set in a "V" shape, when the cleaning brush cleans the surface of the PCB board, the dust cleaned off moves obliquely backward with the movement of the PCB board and is then cleaned and absorbed by the vacuum cleaning brush assembly, ensuring the cleaning effect of the PCB board.

[0014] 2. The negative pressure adsorption assembly is constructed by setting a negative pressure mounting base on a negative pressure seat and a negative pressure adsorption seat on the side of the negative pressure mounting base. The negative pressure adsorption seat is equipped with a negative pressure adsorption groove and a negative pressure adsorption hole on the conveyor belt. When the PCB board is conveyed on the conveyor belt, the negative pressure suction pipe draws air outward, thereby generating negative pressure in the negative pressure chamber. Through the air guide hole, a negative pressure adsorption force is generated on the PCB board at the negative pressure adsorption groove and the negative pressure adsorption hole, so that the PCB board can be stably attached to the conveyor belt for conveying, ensuring the cleaning effect.

[0015] 3. The upper brush cleaning component is fixed to the base based on the vacuum quick-release assembly. The vacuum quick-release assembly is achieved by setting a vacuum suction pipe on the base and a vacuum suction seat at the bottom of the vacuum suction pipe. A vacuum connector is set on the vacuum suction seat and inserted into the vacuum dust removal seat. By inserting the vacuum connector into the vacuum dust removal hole of the vacuum dust removal seat of the upper brush cleaning component, and then rotating the locking rod, the vacuum dust removal seat and the upper brush seat are locked and fixed to the vacuum suction pipe. This allows the upper brush cleaning component to be quickly disassembled and assembled while performing vacuum dust removal. Combined with the upper partition plate fixedly connected inside the upper brush seat and several upper vacuum suction holes evenly opened on the upper partition plate, the uniformity of the dust removal effect is ensured, reducing space occupation while ensuring the cleaning effect of the PCB board. At the same time, the lower brush cleaning component is equipped with several lower vacuum suction pipes at the bottom of the lower brush seat. This allows the lower brush cleaning component to be easily disassembled and cleaned while also performing vacuum dust removal, ensuring the cleaning effect of the PCB board.

One end of the vacuum cleaning brush assembly 4 extends to the middle of the infeed negative pressure adsorption conveyor line 2, and the other end extends obliquely to the infeed negative pressure adsorption conveyor line 3. At the side end of the negative pressure adsorption conveyor line 2, the PCB board enters through the negative pressure adsorption conveyor line 2 and passes through the vacuum cleaning brush assembly 4, thereby achieving simultaneous dust cleaning on both sides of the PCB board, which greatly improves the cleaning efficiency. At the same time, since the vacuum cleaning brush assembly 4 is set at an angle and is arranged in a "V" shape, when the cleaning brush cleans the surface of the PCB board, the dust that is cleaned off moves backward with the movement of the PCB board and is then cleaned and absorbed by the vacuum cleaning brush assembly 4, ensuring the cleaning effect of the PCB board.

The interval between the active belt drive wheel 23 and the passive belt drive wheel 24 of the feeding negative pressure adsorption conveying line 2 gradually decreases from the side to the middle, while the interval between the active belt drive wheel 23 and the passive belt drive wheel 24 of the discharging negative pressure adsorption conveying line 3 gradually increases from the side to the middle.

The bottom of the negative pressure base 21 is fixedly connected to several negative pressure suction pipes 277 that are connected to the negative pressure chamber 275. When the PCB board is conveyed on the conveyor belt 25, the negative pressure suction pipes 277 suck out air, thereby generating negative pressure in the negative pressure chamber 275. Through the air guide holes 276, a negative pressure adsorption force is generated on the PCB board at the negative pressure adsorption tank 273 and the negative pressure adsorption hole 274, so that the PCB board can be stably attached to the conveyor belt 25 for conveying, ensuring the cleaning effect.

By fixing the lower equalization plate 414 inside the lower brush seat 411 and opening several lower vacuum suction holes 415 on the lower equalization plate 414, the uniformity of the lower suction is ensured.

The upper brush cleaning assembly 42 includes an upper brush seat 421 and at least one upper cleaning brush 422 rotatably connected to the upper brush seat 421.
