Abstract
A wandering star wheel for grinding quartz crystal wafers comprises a wandering star wheel (1). A group of teeth (1-1) are arranged on the periphery of the wandering star wheel (1). A group of rectangle holes (2) are formed in the wandering star wheel (1). The rectangle holes (2) are evenly arranged in the wandering star wheel (1) around a central hole (1-2) of the wandering star wheel (1). The range of an included angle alpha between one side of each rectangle hole and the diameter of the wandering star wheel (1) is 110-170 degrees. The wandering star wheel for grinding the quartz crystal wafers has the advantages that through the change of the included angle between traditional rectangle holes and the wandering star wheel, the strength of the novel wandering star wheel is superior to that of a traditional wandering star wheel. Moreover, the service life of the wandering star wheel is greatly prolonged, and the qualification rate of grinding of the quartz crystal wafers is improved by 1-2%.
Description
Technical field
The utility model relates to the quartz wafer technical field, is specifically related to a kind of grinding quartz crystal wafers erratic star wheel.
Background technology
At present, grinding quartz crystal wafers is fixed 90 ° of angles with rectangular opening and the diameter of erratic star wheel, and this erratic star wheel in use intensity is not fine, when particularly erratic star wheel thickness is less than 0.1mm, damages easily, and the grinding wafers qualification rate is not very high, and service life is shorter.
The utility model content
The purpose of this utility model is exactly to fix 90 ° of angles for present grinding quartz crystal wafers with rectangular opening and the diameter of erratic star wheel, this erratic star wheel in use intensity is not fine, when particularly erratic star wheel thickness is less than 0.1mm, damage easily, the grinding wafers qualification rate is not very high, service life is the deficiency of weak point, and a kind of grinding quartz crystal wafers erratic star wheel is provided.
The utility model comprises erratic star wheel, the erratic star wheel periphery is provided with one group of tooth, have one group of rectangular opening on the erratic star wheel, and each rectangular opening is evenly arranged on the erratic star wheel around the centre bore of erratic star wheel, one side of each rectangular opening is 110 °～170 ° with the angle α scope of erratic star wheel diameter.
The utility model has the advantages that: by changing traditional rectangular opening and the angle of erratic star wheel, so that novel erratic star wheel intensity is better than the intensity of traditional erratic star wheel, and improves service life greatly, the grinding wafers qualification rate improves 1～2 percentage point.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is existing grinding quartz crystal wafers erratic star wheel structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises erratic star wheel 1, erratic star wheel 1 periphery is provided with one group of tooth 1-1, have one group of rectangular opening 2 on the erratic star wheel 1, and each rectangular opening 2 is evenly arranged on the erratic star wheel 1 around the centre bore 1-2 of erratic star wheel 1, and one side of each rectangular opening is 110 °～170 ° with the angle α scope of erratic star wheel 1 diameter.
Claims (1)
