BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to an etching device, and particularly, to an etching device used for etching a curved glass sheet. 
         [0003]    2. Description of Related Art 
         [0004]    In glass manufacturing processes, a glass surface may be etched by an etching device. The etching device may include a plurality of nozzles arranged side by side. A plurality of glass sheets may be placed vertically below the nozzles. When etching the glass sheet, an etching solution may go down along a side surface of the glass sheet with a uniform speed. However, the above-mentioned etching device may be only fit to etch a flat glass sheet. When such an etching device is used for etching a curved glass sheet, a flow speed of the etching solution along a side surface may not be uniform due to an uneven surface of the glass sheet. Thus, a staying time of the etching solution on the side surface may vary, and the glass sheet may be etched unevenly. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0009]    Referring to  FIG. 1 , an embodiment of an etching device  100  is used to etch a plurality of curved glass sheets  200 . The etching device  100  comprises a base  10 , a receiving member  30 , an air compressor  40 , and a plurality of rotating members  50 . The receiving member  30  is configured for receiving an etching solution, and is connected to the air compressor  40 . The etching solution may be jetted out from the receiving member  30  which is controlled by the air compressor  40 . The plurality of rotating members  50  are rotatably mounted on the base  10 , adjacent to the receiving member  30 . The plurality of curved glass sheets  200  are fixed to the rotating member  50 . The etching solution may be sprayed onto surfaces of the plurality of curved glass sheets  200 . 
         [0010]    Referring to  FIGS. 2 and 3 , the base  10  is configured for mounting the receiving member  30  and the plurality of rotating members  50 . In the illustrated embodiment, the base  10  is substantially plate-like. A first mounting hole  11  and a plurality of second mounting holes  13  are defined in the base  10 . The first mounting hole  11  is defined at a center of the base  10 . The plurality of second mounting holes  13  are defined around the first mounting hole  11 , and are arranged evenly on an imaginary circle which is concentric with the first mounting hole  11 . 
         [0011]    The receiving member  30  comprises a receiving portion  31  and a cover portion  33 . The receiving portion  31  is substantially cylindrical, and is mounted in the first mounting hole  11  accordingly. The receiving portion  31  comprises a first end surface  311  away from the base  10 ; a second end surface  312  opposite to the first end surface  311 , adjacent to the base  10 ; and a side surface  313  connecting the first end surface  311  and the second end surface  312 . A receiving hole  3110  is defined at a center of the first end surface  311 , extending along an axial direction of the receiving portion  31 . The second end surface  312  is fixed to the base  10 . A plurality of spraying holes  3130  are defined on the side surface  313  around the receiving hole  3110 , extending along a radial direction of the receiving portion  31 . The plurality of spraying holes  3130  are distributed all over the side surface  313 . In the illustrated embodiment, the plurality of spraying holes  3130  are arranged uniformly, forming a layered structure along the axial direction. Each layer of the plurality of spraying holes  3130  is substantially parallel to the first end surface  311 . It is to be understood that the plurality of spraying holes  3130  may be arranged unevenly. The cover portion  33  is disposed on the first end surface  311  to cover the receiving portion  31 . The cover portion  33  is substantially cylindrical, and defines a communicating hole  330  at a center of the cover portion  33 . The communicating hole  330  interconnects with the receiving hole  3110 . 
         [0012]    The air compressor  40  is connected to the communicating hole  330 , such that when the air compressor  40  generates high pressure air, the etching solution can be jetted out from the receiving portion  31 . 
         [0013]    It is understood that the air compressor  40  may be omitted, and in alternative embodiments, the receiving member  30  may be rotatably placed on the base  10 , and may be driven to rotate by a driving member, such that the etching solution can be jetted out by a centrifugal force. 
         [0014]    Each of the plurality of rotating members  50  is mounted in one of the plurality of second mounting holes  13 . Each of the plurality of rotating members  50  comprises a main body  51 , and a rotating shaft  53  connected to the main body  51 . The main body  51  is substantially cylindrical, and is placed opposite to each of the plurality of spraying holes  3130  of the receiving member  30 . The plurality of curved glass sheets  200  may be mounted on a side surface of the main body  51 . In the illustrated embodiment, the plurality of curved glass sheets  200  are adhered to the side surface of the main body  51  with adhesive. Each rotating shaft  53  passes through one of the plurality of second mounting holes  13 , and is then rotatably fixed to the base  10 . In one embodiment, the plurality of rotating members  50  may further comprise a plurality of sucking discs placed on the main body  51  to adhere the plurality of curved glass sheets  200 . In another embodiment, the plurality of rotating members  50  may further comprise a plurality of latching modules placed on the main body  51  to securely latch the plurality of curved glass sheets  200 . 
         [0015]    The etching device  100  further comprises a plurality of driving members (not shown) to drive the rotating members  50  to rotate relative to the base  10 . In the illustrated embodiment, a quantity of the driving members is the same as that of the plurality of rotating members  50 . Each of the plurality of driving members is connected to one of the plurality of rotating members  50 . It is to be understood that the quantity of the plurality of driving members may be smaller than that of the plurality of rotating members  50 , and in alternative embodiments, one or more gear assemblies connects the plurality of rotating members  50 . 
         [0016]    During etching process, the plurality of glass sheets  200  are mounted on the side surface of the main body  51 , then the plurality of rotating members  50  rotate, and the etching solution is sprayed onto surfaces of the plurality of glass sheets  200 . Because the plurality of glass sheets  200  can be rotated with the plurality of rotating members  50 , and the etching solution can be sprayed onto the plurality of glass sheets  200  at different angles and different heights, the plurality of glass sheets  200  may be evenly etched with the etching solution, even if the surfaces are uneven. 
         [0017]    It can be appreciated that the etching device  100  may be used for etching a flat glass sheet, or with other etching solutions. The etching device  100  may be used for etching objects made of other materials. 
         [0018]    It is to be understood, however, that even though numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
