the storage rack 100 is provided with a second image capturing device (not shown in the figure) for capturing position data of a die on the storage rack 100, and may also be a camera, the storage rack 110 without a die is photographed for the first time, a rectangular plane coordinate system is established for the obtained image information, a point set arranged in a matrix is selected on the whole storage rack 110 according to a preset value, and corresponding numbering is also performed, where the preset value is, for example, 50 points, and when the transfer piece 400 transfers a die, the storage rack 100 is caused to move in two directions through the position data, so that the die is right at a to-be-stored area, that is, a next to-be-stored point.
And after the material storing film member 110 is operated by the voice coil motor 133, the air floating inner sleeve 132 is moved, so that the supporting block 120 and the material storing film member 110 move together, and the supporting area formed by the supporting block 120 supports the material storing film member 110, and the area of the supporting area is not less than the area of the material storing film member 110 where the crystal grains are stored.
And then the steps S1-S4 are not repeated, wherein when the step S4 is performed, the step S2 in the next repeating cycle is performed synchronously, thereby improving the sorting efficiency.
Further, when step S2 is performed, synchronization is also performed to step S5: and (4) correcting the deviation, namely comparing the horizontal side edge of the crystal grain with the X axis through the coordinate system established in the step (S2) to obtain a deviation angle a, rotating the servo motor 152 by a corresponding angle at the moment to deflect the material storage film frame 124, when the crystal grain is adhered to the material storage film 110, reversely rotating the servo motor 152 by a corresponding angle to reset the material storage film frame 124, and when the deviation angle is 0 degrees, not operating the servo motor 152. This step enables the crystal grains adhered to the stock film member 110 to maintain the same angular arrangement.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
