By placing a plurality of discs to be polished on the rotating support fixture 120 one by one, the rotating support fixture 120 rotates to drive the corresponding discs to rotate. At the same time, the robot arm 220 drives the coarse polishing assembly 240 and the fine polishing assembly 250 toward the rotating support fixture 120 by driving the connecting frame 230. The driving end of the robot arm 220 rotates to polish a plurality of discs on the rotating support fixture 120 at the same time by using the coarse polishing assembly 240. After the coarse polishing is completed, the robot arm The driving end of 220 rotates again, and the fine grinding component 250 is used to grind each disc on the rotating supporting fixture 120 again at the same time to improve the smoothness of the disc surface. The disc grinding process is automatically completed by the disc grinding processing equipment of the present application, and multiple discs can be grinded at the same time according to the preset construction process, and the rotation direction of the rough grinding component 240 and the fine grinding component 250 is opposite to the rotation direction of the disc driven by the rotating supporting fixture 120, thereby improving the grinding processing efficiency and accuracy of the disc.

[0032] Reference Figure 2 and Figure 3 It is understood that the rotary support fixture 120 includes a first support frame 121, a rotary cylinder 122, and a support bracket 123. The rotary cylinder 122 is disposed within the first support frame 121. The driving end of the rotary cylinder 122 passes through the top of the first support frame 121 and is connected to the bottom of the support bracket 123. The support bracket 123 is used to place the disc. A positioning disc structure is provided on the top of the support bracket 123. The disc to be polished is placed on the support bracket 123. The rotary cylinder 122 drives the support bracket 123 to rotate, thereby driving the disc on the top of the support bracket 123 to rotate, so as to better cooperate with the polishing head mechanism 200 and improve the disc polishing efficiency.

[0033] Reference Figure 3It can be understood that the rotating supporting fixture 120 also includes a second support frame 124, an ejection cylinder 125 and a connecting rod 126.

[0034] Reference Figure 1 and Figure 2 As will be appreciated, the polishing table mechanism 100 further includes a cooling assembly 130, which is disposed on the first frame 110 and adjacent to the rotating support fixture 120. This assembly is used to cool the disc being polished. During polishing, the high-speed rotation of the disc itself, as well as the high-speed rotation of the coarse polishing assembly 240 and the fine polishing assembly 250, generates high heat on the disc surface. This excessive heat can easily lead to damage. Cooling the disc with the cooling assembly 130 provides cooling protection.

[0035] Reference Figure 3 It is understood that the cooling assembly 130 includes a plurality of universal bamboo tubes 131. The number of universal bamboo tubes 131 corresponds to the number of rotating support fixtures 120. Each universal bamboo tube 131 is provided on the first frame 110 and is located beside the corresponding rotating support fixture 120. The first frame 110 is also provided with a plurality of drainage holes 111. The universal bamboo tubes 131 can arbitrarily adjust the angle of the water jet to better align each disc, thereby achieving a cooling effect for each disc during grinding. At the same time, the first frame 110 is provided with drainage holes 111 for draining the coolant ejected from the universal bamboo tubes 131.

[0036] Reference Figure 1 and Figure 2It is understood that the sanding table mechanism 100 further includes a sanding pad replacement assembly 140, which is disposed on the first frame 110 and is used to replace the sanding pads on the sanding heads of the coarse sanding assembly 240 or the fine sanding assembly 250. To achieve a good sanding effect, the coarse sanding assembly 240 and the fine sanding assembly 250 need to replace the sanding pads on the sanding heads after sanding several discs. The sanding pad replacement assembly 140 automatically replaces the sanding pads on each sanding head, thereby improving the quality and efficiency of disc sanding.

[0037] Reference Figure 4 It can be understood that the polishing skin replacement assembly 140 includes a replacement bracket 141, several silos 142 and an upper cylinder 143 corresponding to the silo 142. The replacement bracket 141 is arranged on the first frame 110, and several silos 142 are arranged at intervals on the replacement bracket 141. The silo 142 is used to place the polishing skin. The upper cylinder 143 is respectively corresponding to the upper cylinder 143 and is arranged in the replacement bracket 141. The driving end of the upper cylinder 143 passes through the replacement bracket 141 and the silo 142, and is against the polishing skin in the silo 142. Specifically, in an embodiment of the present application, there are four grinding heads on the coarse grinding component 240 and the fine grinding component 250 respectively, and there may be two grinding skin replacement components 140, one providing coarse grinding skin for the coarse grinding component 240, and the other providing fine grinding skin for the fine grinding component 250. Four silos 142 are provided on each replacement bracket 141, and the interval between two adjacent silos 142 is the same as the interval between adjacent grinding heads. The robotic arm 220 drives the coarse grinding component 240 or the fine grinding component 250 to the top of the replacement bracket 141, and aligns the grinding heads one by one with the silos 142, and extends the driving end of the lifting cylinder 143 to lift the grinding skin of the silo 142 and make it contact with the grinding head to complete the automatic installation of the grinding head and the grinding skin, thereby realizing the replacement process of the grinding skin and improving the quality and efficiency of disc grinding.

[0038] Reference Figure 1 and Figure 5 It is understood that the grinding head mechanism 200 further includes a film tearing assembly 260, which is disposed on the second frame 210. The film tearing assembly 260 is used to remove the grinding skin from the coarse grinding assembly 240 or the fine grinding assembly 250. Before replacing the grinding skin on each grinding head, the old grinding skin on the grinding head needs to be torn off. The robotic arm 220 moves to the position of the film tearing assembly 260, and the film tearing assembly 260 automatically tears off the grinding skin on each grinding head. The robotic arm 220 then moves to the position of the grinding skin replacement assembly 140 to automatically install the grinding skin on each grinding head, thereby completing the grinding skin replacement process and improving the quality and efficiency of disc grinding.

[0039] Reference Figure 5 It can be understood that the film tearing assembly 260 includes a film tearing bracket 261, a support block 262, a clamping cylinder 263 and a waste basket 264. The film tearing bracket 261 is arranged on the second frame 210, and a plurality of support blocks 262 are provided and are arranged at intervals on the film tearing bracket 261. A fixed clamping block 265 is provided on the top of each support block 262. The number of clamping cylinders 263 corresponds to the number of support blocks 262. Each clamping cylinder 263 is arranged on the corresponding support block 262. The driving end of the clamping cylinder 263 is provided with a movable clamping block 266. The clamping cylinder 263 is used to drive the movable clamping block 266 to move closer to or away from the fixed clamping block 265. Specifically, in an embodiment of the present application, the interval between two adjacent support blocks 262 is the same as the interval between adjacent grinding heads. The robotic arm 220 drives the coarse grinding assembly 240 or the fine grinding assembly 250 to move above the support block 262, and moves the grinding skin part of the grinding head to between the fixed clamp 265 and the movable clamp 266. The clamping cylinder 263 drives the movable clamp 266 toward the fixed clamp 265, thereby clamping the grinding skin. The robotic arm 220 moves upward again to leave the film tearing assembly 260, and the operation of tearing off the old grinding skin on the grinding head can be completed. At the same time, the clamping cylinder 263 drives the movable clamp 266 away from the fixed clamp 265 again, so that the clamped old grinding skin naturally falls off into the waste basket 264, completing the storage of the old grinding skin. By cooperating with the movable clamp 266 and the fixed clamp 265 on the clamping cylinder 263, the grinding skin on each grinding head is automatically torn off, and the grinding skin replacement component 140 is used to automatically install the grinding skin on each grinding head, thereby completing the grinding skin replacement process and improving the quality and efficiency of disc grinding.

[0040] Reference Figure 5 As can be understood, the connecting frame 230 is shaped like an isosceles right triangle, the driving end of the robotic arm 220 is connected to the hypotenuse of the connecting frame 230, and the rough grinding assembly 240 and the fine grinding assembly 250 are respectively arranged on the two right-angled sides of the connecting frame 230. After the rough grinding is completed, the robotic arm 220 can simply rotate to switch from the rough grinding assembly 240 to the fine grinding assembly 250, thereby improving the grinding efficiency.
