Examples
Embodiment 1
[0041] The actual use steps of the present invention: (with 285-290, 3-inch circular silicon wafers, 211pcs waiting for confirmation. According to the principle, the single maximum count n=56.)
[0042] 1. Turn on the switch of the device, and place the basket containing silicon wafers on the balance.
[0043] 2. When the display is stable, click Tare.
[0044] 3. Place the test weight on the basket and confirm that the weight display is consistent with the weight identification.
[0045] 4. Enter the silicon wafer thickness 285-290, and select "3 inches", "wafer".
[0046] 5. Put the wafers to be counted into the basket in batches, and click "Accumulate".
[0047] 6. If too many pieces are put in at one time, it will display "Exceeded" and will not be included in the cumulative number of pieces.
[0048] 7. Repeat steps 5-6 to get the final total number of pieces. Get "over", "56", "55", "over", "55", "45", respectively.
[0049] 8. "Accumulated number of pieces" display...
Embodiment 2
[0052] Shipment inspection, N14, 295-300 microns, 501pcs, wafers, 1pcs filter paper every 50pcs interval, of which 1 knife silicon wafer is 51pcs, the final inspection uses the device of the present invention for full inspection, and the final inspection requires 500pcs / box, 50pcs / Knife.
[0053] The inspection is as follows:
[0054]
[0055]
Embodiment 3
[0057] 5-inch single reference surface, asymmetric chamfered silicon wafer, thickness 525-530 microns. The number of slices is unknown, and the number of slices is calculated using the device and method of the present invention.
[0058] 1. Input the upper and lower lines of the thickness to get the single maximum count value n=104pcs.
[0059] 2. Select the size "5 inches", "single reference plane", and press "cumulative" to count.
[0060] 3. Divided into multiple counts, respectively "52", "46", "68", "42", "45", a total of 253pcs.
[0061] 4. Checked by manual counting method, it is 253pcs, which is consistent with the result of the counting device.
