Disclosure of Invention

One of the purposes of the invention is to provide an automatic solar cell blanking machine, which can realize automatic detection of cells with water in a flower basket.

The invention is realized by the following technical scheme: the utility model provides an automatic blanking machine of solar wafer for carry out the unloading to the basket of flowers of the output after the machine of making herbs into wool, the blanking machine includes the organism and sets up controller, extracting device and the lift platform on the organism, and controller control extracting device and lift platform action, its characterized in that: the blanking machine is also provided with a detection device which is a camera arranged on the machine body, the camera faces the lifting platform, the camera photographs the battery plates in the flower basket when the controller drives the flower basket to move to the middle of the visual field opposite to the camera by controlling the lifting platform to obtain the number of the battery plates in the flower basket, and transmitting the obtained number of the battery pieces to the controller, the controller compares the received number of the battery pieces with the number of the battery pieces which are pre-stored in the controller and are supposed to be in the basket, if the obtained number of the battery pieces is equal to the number of the pre-stored battery pieces, the flower basket is proved to be not provided with the battery pieces with water, the judgment result is OK, if the number of the obtained battery pieces is smaller than the number of the pre-stored battery pieces, the fact that the battery pieces with water are arranged in the basket is indicated, the judgment result is NG, and therefore automatic detection of the battery pieces with water in the basket under the flocking process is achieved.

The formation of the water-carrying battery piece is mainly the phenomenon that when a flower basket filled with the battery pieces passes through each groove body of a texturing process machine, fragments of some battery pieces after being damaged are adhered to other battery pieces through liquid. Through the long-time observation discovery in scene, the formation of water-carrying battery piece must be accompanied by the damaged condition of battery piece and takes place, and the damaged back of battery piece under the 90% condition, basket of flowers pole can not support the damaged battery piece, and the battery piece can drop promptly to cause certain position in the basket of flowers to lack the piece, at this moment, detect and count the quantity of battery piece through the camera and just can detect out water-carrying battery piece.

The automatic solar cell blanking machine fills the blank of 'automatic detection of water-carrying cells' by installing the camera as the detection device, realizes real-time uninterrupted automatic detection, and blocks the condition that a large number of water-carrying cells flow into a diffusion process. The detection device can replace manual work to stabilize effectual the examining of the water battery piece condition in the flower basket to it is efficient to examine, saves a large amount of human costs.

The blanking machine is provided with a first conveying mechanism and a second conveying mechanism, and when the number of the battery pieces in the flower basket detected by the detection device is equal to the preset number, the flower basket with the battery pieces on the lifting platform is conveyed by the first conveying mechanism; when the number of the battery pieces in the flower basket detected by the detection device is not equal to the preset number, the flower basket with the battery pieces on the lifting platform is conveyed by the second conveying mechanism.

In the process of photographing, the camera is easy to have the problem of image overexposure. The image overexposure is that the periphery of the flower basket is hollowed, after the light source emits light from the camera side, the light passes through the gaps of the battery pieces and the flower basket, irradiates the automatic surface and returns to the camera on the original way, so that the image overexposure is caused, and the identification of the edges of the battery pieces is influenced. For the case of image overexposure, the first solution of the present invention is: the shooting angle of the camera is inclined upwards, and an included angle of 30 degrees is formed between the shooting angle of the camera and the horizontal plane.

The camera is used for shooting in an inclined mode, namely the shooting angle of the camera is not parallel to the flower basket in the vertical direction, and the angle is about 30 degrees, so that the light of the light source is blocked to irradiate the surface of the equipment through the gap of the battery piece and then return to the camera, only the light reflected by the edge of the battery piece exists in the image, and the subsequent software can conveniently identify and judge the edge of the battery piece.

The second solution is: black light absorption cloth is attached to the vertical surface of the lifting platform, which is located behind the flower basket, and the shooting angle of the camera is in the horizontal direction.

In the invention, the distance between the camera and the black light absorption cloth is 650-700 mm.

The mode that the black light absorption cloth is pasted on the surface of the equipment behind the flower basket is adopted, and the light absorption cloth is added, so that the light reaching the light absorption cloth through the gaps of the battery pieces can be absorbed, the light reflected by the edges of the battery pieces only exists in an image, and the identification and judgment of the edges of the battery pieces by subsequent software are facilitated.

The invention also aims to provide a control method of the automatic solar cell blanking machine.

The invention is realized by the following technical scheme: the control method of the automatic solar cell blanking machine is characterized in that: the control method comprises the steps that the material taking device, the lifting platform and the camera are controlled to act through the controller, when the controller drives the flower basket to move to the middle of a visual field opposite to the camera through controlling the lifting platform, the camera is used for shooting the battery pieces in the flower basket, the number of the battery pieces in the flower basket is obtained, the obtained number of the battery pieces is transmitted to the controller, the controller compares the received number of the battery pieces with the number of the battery pieces pre-stored in the controller, if the obtained number of the battery pieces is equal to the number of the pre-stored battery pieces, it is indicated that no water-carrying battery pieces exist in the flower basket, the determination result is OK, if the obtained number of the battery pieces is smaller than the number of the pre-stored battery pieces, it is indicated that water-carrying battery pieces exist in the flower basket, the determination result is NG, and automatic detection of the water-carrying battery pieces in the flower basket is achieved.

firstly, when the lower half part of a flower basket moves to the middle of the visual field of a camera, a controller informs the camera right in front of the flower basket to take a picture for the first time, the number of battery pieces obtained by taking the picture for the first time is transmitted to the controller, the controller compares the number of received battery pieces with the number of half of the battery pieces pre-stored in the controller, if the number of the obtained battery pieces is equal to the number of half of the pre-stored battery pieces, the lower half part of the flower basket is determined to have no battery pieces with water, the determination result is OK, if the number of the obtained battery pieces is less than the number of half of the pre-stored battery pieces, the lower half part of the flower basket is determined to have the battery pieces with water, and the determination result is NG;

after the lower half part of the flower basket is detected, the controller controls the flower basket to continuously descend, when the upper half part of the flower basket moves to the middle of the visual field of the camera, the controller informs the camera right in front of the flower basket to take a second photo, the number of the battery pieces obtained by the second photo is transmitted to the controller, the controller compares the number of the received battery pieces with the number of half of the battery pieces pre-stored in the controller, if the number of the obtained battery pieces is equal to the number of half of the pre-stored battery pieces, the upper half part of the flower basket is proved to have no water-carrying battery pieces, the judgment result is OK, if the number of the obtained battery pieces is smaller than the number of half of the pre-stored battery pieces, the upper half part of the flower basket is proved to have water-carrying battery pieces, and the judgment result is NG;

and after the upper and lower detection are finished, the controller judges the two results integrally again, if the two judgment results are OK, the whole flower basket is judged as OK, and if one judgment result is NG, the whole flower basket is judged as NG.

In the shooting process of the camera, the problem of virtual focus of images is easy to occur. The virtual focus of the image is because 50 cells in the flower basket form a 180mm × 240mm detection visual field, and the depth of the lens is very small, so that the cells on two sides are not in the focal length of the lens in the direction of 240mm, the image is blurred, and the number of the cells is easy to misjudge.

The method comprises the following steps of carrying out quantity identification on the edges of the battery pieces in the binary image by using a CogCaliperTool tool in a camera, and thus obtaining the quantity of the photographed battery pieces:

1. performing image analysis area framing on an input binary image by using a CogCaliperTool tool, framing an area containing a battery piece in the binary image to be used as a battery piece framing area, and keeping the projection direction of the framing area parallel to the edge of the battery piece;
