Detailed description of the invention
Known with reference to the accompanying drawings, the utility model is specifically related to a kind of grid line automatic rinser, mainly complete in solar battery sheet printing process of rework, to the removing of substandard products surface grid line, specifically, to the grid line and the slurry that also do not carry out on the substandard solar cell sheet of sintering are removed, can make cell piece carry out again technique and recycle.
According to above function, the grid line automatic rinser of design as shown in Figure 1, it is mainly by installation compositions such as frame 10, belt 1, sensor 2, roller 8 and leading screws, there is belt 1 in the tiling of the middle and lower part of frame 10, belt 1 is propped up by two rollers, can realize the rotation of belt 1, and transport solar panels, belt 1 is driven by the 3rd motor 7 of being located at frame 10 1 sides, above belt 1, be provided with framework 5, in framework 5, wiper mechanism is housed, wiper mechanism can move up and down along with framework 5, realizes wiper mechanism and solar panels Surface Contact; Be provided with 4 flexible footing 9 at the lower surface of framework 5, the bottom of footing 9 and solar panels Surface Contact, and coordinate compression solar panels with belt 1, and preventing from rocking, wiper mechanism can be to solar panels surface clean.
Wiper mechanism in the utility model be mainly one can spinning roller 8, roller 8 drives by the first motor 3, the first motor 3 is provided with in framework 5, the power output shaft of the first motor 3 carrys out driving rolls 8 by belt transport and rotates, below framework 5 both sides, front and back, be respectively equipped with roller 8, can realize double and clean; In addition, in order to improve the area of cleaning, improve cleaning efficiency, wiper mechanism can move left and right, and completes by the second motor 6, and wherein the second motor 6 is provided with frame 10 1 sides, there is the second motor 6 to drive leading screw, leading screw coordinates with feed screw nut, and feed screw nut is fixed on wiper mechanism, realizes leading screw and drives wiper mechanism to move left and right.
The utility model, in order to realize automatic control, is provided with the sensor 2 being fixed in frame 10 at the end of belt 2, realize by sensor 2 start stop operation of controlling 3 motors.
Framework 5 in the utility model moves up and down, and the mechanism of realization passes through connecting rod or connecting plate at the upper surface of framework 5, is connected with the cylinder 3 of being located at frame 10 1 sides.
Running part in the utility model and cleaning part coordinate, and complete the cleaning of solar battery sheet, and its concrete steps are as follows:
1) cell piece can enter workspace by belt moving 1, and, under framework 5, this action is controlled by the 3rd motor 7, is located by sensor 2;
2) framework 5 can be vertically downwards until footing 9 be pressed cell piece, and base angle adopts flexible material to make, and utilizes stiction to fix cell piece, and this action is controlled by cylinder 4;
3) on the roller 8 that flexible soft brush is made, have absolute ethyl alcohol, roller 8 rotations, this action is controlled by the first motor 3, and leading screw drives wiper mechanism to move left and right along horizontal positioned, and this action is controlled by the second motor 6;
