[0016] Reference Figures 1 to 3 As shown, the utility model provides an auxiliary operating table for a grinding machine, comprising: a grinding operating table 1 and a wafer clamping bracket 3. The wafer clamping bracket 3 is fixed to the upper surface of the grinding operating table 1 by fastening bolts 32.

[0017] The upper surface of the grinding operating table 1 is connected to a slider 46 through a limiting slide groove 12, and a fixed seat 47 is welded to the upper end of the slider 46. The upper end of the fixed seat 47 supports a U-shaped dust removal plate 4, and the upper and lower ends of the U-shaped dust removal plate 4 are connected to a small vacuum cleaner 5 through a dust suction pipe 51. The inner end surface of the U-shaped dust removal plate 4 is symmetrically provided with a first dust suction port 44 and a second dust suction port 45, and a soft brush 41 is glued to the middle of the first dust suction port 44 and the second dust suction port 45.

[0018] First, clamp and fix the wafer to be ground with the wafer clamping bracket 3, turn on the small vacuum cleaner 5, manually pull the U-shaped dust removal plate 4 to move left and right, so that when the U-shaped dust removal plate 4 moves to the wafer, the first dust suction port 44 and the second dust suction port 45 vacuum the upper and lower surfaces of the wafer, and at the same time, the soft brush 41 gently cleans the wafer surface. After cleaning is completed, remove the wafer and place it on the grinder for grinding.

[0019] In this embodiment, a counterweight pad 11 is fixed to the lower surface of the grinding table 1, and a strip-shaped limiting slot 12 is provided on the upper surface of the grinding table 1. A fixing hole 14 is provided in front of the limiting slot 12, and a fastening bolt 32 is connected to the fixing hole 14. A tool frame 13 is welded to the right side of the grinding table 1.

[0020] As a preferred embodiment, a counterweight base pad 1 ensures the stable placement of the grinding table 1. Multiple sets of fixing holes 14 are provided on the surface of the grinding table 1, making it easy to select the appropriate hole position to fix the wafer clamping bracket 3.
