The clamping cylinder D7 controls the rotation of the clamping disc D4 to release the clamping lever D6, thus realizing the replacement of the two glass trays I.

[0046] The first grinding machine uses 30μ sandpaper to remove adhesive. During grinding, water is sprayed through the spraying mechanism C5, the grinding paper is automatically replaced by the glass plate changing device D, the water is changed by the bubbling ultrasonic cleaning device B, and the high-pressure air is blown dry by the blowing device E. The second grinding machine uses 16μ sandpaper for coarse grinding. During grinding, water is sprayed through the spraying mechanism C5, the grinding paper is automatically replaced through the glass plate changing device D, the water is changed through the bubbling ultrasonic cleaning device B, and the high-pressure air is blown dry through the blowing device E. The third grinding machine uses 3μ sandpaper for fine grinding. During grinding, water is sprayed through the spraying mechanism C5, the grinding paper is automatically replaced through the glass plate changing device D, the water is changed through the bubbling ultrasonic cleaning device B, and the high-pressure air is blown dry through the blowing device E. The fourth grinding machine uses rubber pads for fiber pulling. During grinding, grinding fluid is sprayed through the spraying mechanism C5, and the grinding fluid is stirred by the stirring mechanism F. The rubber pads are automatically replaced by the glass plate changing device D, and the water is changed by the bubbling ultrasonic cleaning device B. The machine is dried by the high-pressure air blowing device E. The fifth grinding machine uses rubber pad polishing. During grinding, the grinding liquid is sprayed by the spraying mechanism C5, the grinding liquid is stirred by the stirring mechanism F, the rubber pad is automatically replaced by the glass plate changing device D, the water is changed by the bubbling ultrasonic cleaning device B, and the high-pressure air is dried by the blowing device E.

[0047] Specifically, when the grinding disc K is moved by the transfer device C, the transverse linear module C2 drives the transport fixture C3 and the grinding fixture C4 to move. The grinding fixture C4 of the first grinding machine clamps the grinding disc K located on the bracket K of the first grinding machine. The transport fixture C3 clamps the grinding disc K located in the grinding station inside the first grinding machine. The transverse linear module C2 of the first grinding machine places the grinding disc K located on the bracket K of the first grinding machine into the grinding station inside the first grinding machine. At the same time, the grinding disc K located in the grinding station inside the first grinding machine is placed into the cleaning station inside the first grinding machine. The grinding disc K located in the cleaning station of the first grinding machine is held by the grinding fixture C4 of the second grinding machine. The grinding disc K located in the grinding station of the second grinding machine is held by the transport fixture C3. The grinding disc K located in the cleaning station of the first grinding machine is placed into the grinding station of the second grinding machine by the transverse linear module C2 of the second grinding machine. At the same time, the grinding disc K located in the grinding station of the second grinding machine is placed into the cleaning station of the second grinding machine. This process is repeated.

[0048] When the spraying mechanism C5 moves above the grinding station, the spraying head C53 can be moved by the spraying cylinder C51. The spraying head C53 sprays water onto the grinding device A. The first to third grinding machines spray water, and the fourth and fifth grinding machines spray grinding fluid. The grinding fluid in the mixing tank F1 is stirred by the mixer F2.

[0049] When cleaning the grinding disc K through the cleaning device B, the transfer clamp C33 is controlled by the transfer clamp cylinder C32 to hold the grinding disc K, and the transfer lifting cylinder C31 is controlled to move the grinding disc K into the cleaning tank B1. Ultrasonic cleaning and / or bubbling cleaning can be used to make the cleaning more thorough.

[0050] When the MT insert on the grinding disc K is ground by the grinding device A, the grinding lifting cylinder C41 controls the grinding pressure seat C44 to move, and the grinding pressure rod C45 presses against the grinding disc K. At the same time, the grinding clamping cylinder C42 controls the grinding jaws C43 to release the grinding disc K.

[0051] After passing through the cleaning station of each grinding machine, the grinding disc K can be dried by the set air blowing device E. During the air blowing, the air blowing cylinder E1 controls the movement of the air blowing hood E2, and at the same time, the air knife E3 blows air onto the grinding disc K. The set air blowing hood E2 prevents water from being blown to the previous station.

[0052] After use, the glass disc I on the grinding device A needs to be replaced. At this time, the glass disc replacement device D can be used to replace the unused glass disc I on the placement rack H with the used glass disc I. During replacement, the glass disc I on the grinding device A is clamped by the glass disc clamping assembly at one end of the clamping arm D3, and the glass disc I on the placement rack H is clamped by the glass disc clamping assembly at the other end of the clamping arm D3. The lifting cylinder D1 controls the rotary motor D2 to rise, the rotary motor D2 controls the clamping arm D3 to rotate, and the lifting cylinder D1 controls the rotary motor D2 to rise and fall, placing the two glass discs I in the corresponding positions, thus realizing the replacement of glass disc I. When the glass disc clamping assembly clamps the glass disc I, the clamping cylinder D7 controls the clamping rotary plate D4 to rotate, and the clamping rotary plate D4 controls the clamping swing arm D5 to swing along the clamping swing shaft D9, so that the glass disc I can be clamped by the clamping swing rod D6.

[0053] After use, the glass disc I is placed on the support plate H2. A limiting block H3 on the support plate H2 easily fixes the position of the glass disc I. Air is blown into the air passages of the support column H1 and the support plate H2, allowing air to enter the air hole I1, thus separating the sandpaper from the glass disc I. The sandpaper pick-up and drop cylinder D82 controls the sandpaper pick-up and drop suction cup D83, causing D83 to hold the sandpaper. The sandpaper pick-up and drop linear module D81 moves the sandpaper pick-up and drop cylinder D82 above the sandpaper collection bucket D85. At this point, the sandpaper pick-up and drop suction cup D83 releases the sandpaper, allowing the used sandpaper to fall into the sandpaper collection bucket D85. The sandpaper pick-up and drop linear module D81 then moves the sandpaper pick-up and drop cylinder D82... 2. Move the sandpaper to the top of the sandpaper storage rack D84. Control the sandpaper pick-up and place suction cup D83 through the sandpaper pick-up and place cylinder D82 so that the sandpaper pick-up and place suction cup D83 picks up the new sandpaper. Move the sandpaper pick-up and place cylinder D82 to the top of the placement rack H through the sandpaper pick-up and place linear module D81 and place the new sandpaper on the glass plate I. Then control the sandpaper pressing cylinder D86 to move down so that the sandpaper pressing roller D88 presses the sandpaper. At the same time, the sandpaper picking-up and place linear module D81 drives the sandpaper pressing bracket D87 to move and press the sandpaper on the glass plate I through the sandpaper pressing roller D88. The first to third grinding machines use sandpaper, and the fourth and fifth grinding machines use rubber pads.
