[0024] When in use, one end of the glass blank block to be polished is clamped by the other end of the clamping member 320, and the corner of the glass blank block can be pressed against the surface of the grinding wheel 210 under the elastic force of each elastic member 340, and the grinding wheel 210 can polish the corner of the glass blank block during the rotation process, and the driving assembly 330 is controlled so that the driving assembly 330 can drive each of the clamping members 320 to rotate synchronously, so that the four corners of the other end of the glass blank block can be in turn against the surface of the grinding wheel 210, and as the grinding wheel 210 rotates, the four corners of the other end of the glass blank block are all polished, and when the other end of the glass blank block After the grinding of the four corners is completed, the direction of the glass blank block is manually turned, and then the other end of the glass blank block to be ground is clamped by the other end of the clamping member 320, so that the four corners at one end of the glass blank block can be in turn abutted against the surface of the grinding wheel 210. As the grinding wheel 210 rotates, the four corners at one end of the glass blank block are all ground, thereby achieving the grinding of each corner of the glass blank block. The grinding device is suitable for use when grinding each corner of the glass blank block. When grinding each corner of the glass blank block by rotating the grinding wheel 210, it is no longer necessary to manually hold the glass blank block, and the labor intensity of workers can be reduced when the production batch is large.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 2 The grinding mechanism 200 also includes a first rotating driving member 220, the output end of which is connected to the grinding wheel 210 for driving the grinding wheel 210 to rotate.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2The grinding wheel 210 is horizontally arranged, and the fixing member 310 is arranged above the grinding wheel 210. The fixing member 310 includes a first rotating shaft 311, at least one fixing block 312 and at least one fixing rod 313. The first rotating shaft 311 is horizontally arranged, and each of the fixing blocks 312 is arranged at one side of the first rotating shaft 311 at intervals along the length direction of the first rotating shaft 311.

During the rotation of the first rotating shaft 311, since the fixing blocks 312 and the fixing rods 313 are respectively located on both sides of the first rotating shaft 311, when the fixing rods 313 rotate upward, the fixing blocks 312 rotate downward, and the end of the glass blank block can be pressed against the surface of the grinding wheel 210.

[0027] As a preferred embodiment, please refer to Figure 1 and Figure 2 The clamping member 320 corresponds to each of the fixed blocks 312 one by one. The clamping member 320 includes a second rotating shaft 321 and a clamping seat 322. The second rotating shaft 321 is tilted. The high end of the second rotating shaft 321 is rotatably mounted on the fixed block 312. The clamping seat 322 is fixedly connected to the low end of the second rotating shaft 321.

[0030] As a preferred embodiment, please refer to Figure 2The driving assembly 330 includes a transmission member 331 and a second rotating driving member 332. The second rotating driving member 332 is fixed on one of the fixed blocks 312. The output end of the second rotating driving member 332 is fixedly connected to the high end of one of the second rotating shafts 321, and is used to drive the corresponding second rotating shaft 321 to rotate. The transmission member 331 is connected to each of the second rotating shafts 321, and is used to convert the rotation of one of the second rotating shafts 321 into the synchronous rotation of each of the other second rotating shafts 321.

[0032] As a preferred embodiment, please refer to Figure 2 One end of each elastic member 340 is connected to the other end of each fixing rod 313 in a one-to-one correspondence. The elastic member 340 can provide a tensile force to the fixing rod 313, so that the fixing rod 313 always has a tendency to rotate upward, the fixing block 312 always has a tendency to rotate downward, and the end of the glass blank block can be pressed against the surface of the grinding wheel 210.

[0033] As a preferred embodiment, please refer to Figure 1 The frame 100 includes a water tank 110, and the grinding wheel 210 is arranged in the water tank 110. Since dust is generated during the grinding process, in order to prevent the dust from flying, an appropriate amount of water is filled in the water tank 110 and the grinding wheel 210 is submerged in the water, which can prevent the dust from flying.

[0034] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0035] When in use, one end of the glass blank block is placed in the clamping cavity 3221, and the other end of the glass blank block is located outside the clamping cavity 3221. Since the elastic member 340 can provide a tensile force to the fixing rod 313, the fixing rod 313 always has a tendency to rotate upward, and the fixing block 312 always has a tendency to rotate downward, so that the end of the glass blank block can be pressed against the surface of the grinding wheel 210. By manipulating the second rotation driving member 332, the second rotation driving member 332 can drive the corresponding second rotating shaft 321 to rotate, and through the transmission action of the transmission member 331, each second rotating shaft 321 can rotate synchronously, so that the four corners of the other end of the glass blank block can be in contact with the surface of the grinding wheel 210 in turn. The grinding wheel 210 is used to grind the corners of the glass blank block. When the four corners at the other end of the glass blank block are ground, the direction of the glass blank block is manually turned, and the other end of the glass blank block is placed in the clamping cavity 3221, and one end of the glass blank block is located outside the clamping cavity 3221, so that the four corners at one end of the glass blank block can be in turn abutted against the surface of the grinding wheel 210, thereby achieving grinding of each corner of the glass blank block. The grinding device is suitable for use when grinding each corner of the glass blank block. When grinding each corner of the glass blank block by rotating the grinding wheel 210, it is no longer necessary to manually hold the glass blank block, and the labor intensity of workers can be reduced when the production batch is large.

[0036] The glass blank grinding device provided by the utility model has the following beneficial effects:

[0037] (1) The clamping seat 322 has a clamping cavity 3221 for accommodating one end of the glass blank block, and the other end of the glass blank block is located outside the clamping cavity 3221. The glass blank block is subjected to the downward force of the clamping seat 322 and the upward force of the grinding wheel 210, so that the glass blank block can be positioned to prevent the glass blank block from jumping in the vertical direction;

[0038] (2) The grinding wheel 210 is disposed in the water tank 110. Since dust is generated during the grinding process, in order to prevent the dust from flying, a proper amount of water is placed in the water tank 110 and the grinding wheel 210 is submerged in the water, thereby preventing the dust from flying.

[0039] (3) The grinding device is suitable for use in grinding the corners of a glass blank block. When the corners of the glass blank block are ground by the rotation of the grinding wheel 210, it is no longer necessary to manually hold the glass blank block. When the production batch is large, the labor intensity of the workers can be reduced.
