The inner surface of the mounting frame 1 is symmetrically provided with mounting slots 10 for engaging the two sides of the protective plate 6, and connecting baffles 8 are symmetrically arranged at both ends of the protective plate 6. The surface length is equal to the width of the end opening of the mounting frame 1, the protective plate 6 is at the top of the transmission roller 2 and the supporting ring 3, and a fixing ring 12 is fixed at a single distance on the two end surfaces of the protective plate 6, and a connecting column 11 is equidistantly installed on the surface of one end of the connecting baffle 8, and one end of the connecting column 11 is engaged and connected with the fixing ring 12, and cleaning strips 7 are equidistantly arranged on the bottom end surface of the protective plate 6, and the surface of the cleaning strips 7 is fitted and connected with the surface of the supporting ring 3, which is convenient for protecting the top of the conveying mechanism, so that when the device is idle, there will be no dust or impurities attached to the surface of the transmission roller 2 and the supporting ring 3, and there is no need for workers to clean it regularly, which has good practicality.

[0021] like Figure 2 and Figure 4As shown, a collecting component is provided at the inner bottom of the mounting frame 1, and the collecting component includes a collecting frame 9 arranged at the inner bottom of the mounting frame 1, and a through groove 14 is symmetrically provided on the inner wall at one end of the collecting frame 9, and a limiting clamping column 13 is arranged inside the through groove 14, and an elastic band 15 is fixed at the inner opening of the through groove 14, and one end surface of the limiting clamping column 13 is fixedly connected to the surface of the elastic band 15, and a limiting clamping groove 16 is symmetrically provided on the inner wall at the opening at one end of the mounting frame 1, and the other end of the limiting clamping column 13 is engaged with the limiting clamping groove 16, and a limiting groove 18 is equidistantly provided on the inner bottom surface of the mounting frame 1, and a ball 17 is arranged inside the limiting groove 18, and the surface of the ball 17 is rollingly fitted with the bottom end surface of the collecting frame 9, so as to collect the acid solution dripping on the printed circuit board, so that the conveying mechanism is not easily corroded, and the number of times the workers clean the conveying mechanism can also be reduced, and the practical effect is good.

[0022] The utility model provides a conveying mechanism for PCB acid cycle etching, and the specific working principle is as follows: when the protective component is installed in the early stage, the cleaning cotton strip 7 is first pushed to move toward the bottom end surface of the protective plate 6, so that the cleaning cotton strip 7 can adhere to the bottom end surface of the protective plate 6, and then the two connecting baffles 8 are pushed to move toward the two ends of the protective plate 6, so that the connecting clamping column 11 on the surface of one end of the connecting baffle 8 is limitedly engaged with the fixing ring 12 at one end of the protective plate 6, so that the connecting baffle 8 and the protective plate 6 can be limitedly connected. When the device is idle, the transmission roller needs to be moved. 2 and the top of the supporting ring 3 are protected. At this time, it is only necessary to push the protective plate 6 to move to the inside of the mounting frame 1 so that the two sides of the protective plate 6 are engaged with the inside of the mounting slot 10, and then pull the connecting baffles 8 at both ends of the protective plate 6 to rotate, so that the connecting baffles 8 can protect the openings at both ends of the mounting frame 1, so that when the device is idle, there will be no impurities or dust attached to the surface of the driving roller 2 and the supporting ring 3, and there is no need for workers to clean them regularly, which is more practical; when the printed circuit board is transported after acid etching, it is necessary to clean the dripping At this time, the collecting frame 9 is pushed to move toward the inner bottom of the mounting frame 1, so that the collecting frame 9 can be limited at the bottom of the driving roller 2 and the supporting ring 3. When the collecting frame 9 moves, the surface of the ball 17 inside the limiting groove 18 will roll and fit with the bottom end surface of the collecting frame 9 until the collecting frame 9 is moved to a suitable position. Then, one end of the limiting column 13 is pulled. At this time, the elastic belt 15 is deformed and generates a rebound force due to the extrusion force until the other end of the limiting column 13 moves to the inside of the through groove 14. At the same time, when the through groove 1 4 is aligned with the opening of the limiting card slot 16, and then one end of the limiting card column 13 is loosened. At this time, the rebound force generated by the elastic band 15 will act on the limiting card column 13, so that the other end of the limiting card column 13 will be limited and engaged to the inside of the limiting card slot 16, so that the collecting frame 9 can be limited and fixed to avoid movement when it is hit. When the printed circuit board is transported by the driving roller 2 and the supporting ring 3, the collecting frame 9 can collect the solution dripping from the printed circuit board to avoid corrosion to the device, and the practical effect is good.
