The material transfer structure 230 in the loading mechanism 200 transports the discs in the first material tray 221 to the polishing table mechanism 100 and places them one by one on the top of each rotating carrier jig 121. The polishing robot arm 320 in the polishing head mechanism 300 drives the polishing head assembly 330 to move to the top of the corresponding rotating carrier jig 121, starts the polishing head assembly 330 and contacts the disc on the rotating carrier jig 121 to complete the polishing of the disc.

[0037] Reference Figure 2It is understood that the polishing support structure 120 also includes a cooling assembly 128, which is disposed on the first frame 110 and is located next to the rotating support fixture 121. The cooling assembly 128 is used to cool the disc being polished. The first frame 110 is also provided with a drainage hole 111. When the disc is being polished, the high-speed rotation of the disc itself and the high-speed rotation of the polishing head assembly 330 generates high heat on the disc surface. Excessive heat can easily lead to damage to the disc. The cooling assembly 128 is provided to cool the disc, providing cooling protection for the disc. Specifically, the cooling assembly 128 includes a plurality of universal bamboo tubes, the number of which corresponds to the number of the rotating support fixtures 121. Each universal bamboo tube is arranged on the first frame 110 and is located on the side of the corresponding rotating support fixture 121. The universal bamboo tube can arbitrarily adjust the angle of the water jet to better align each disc, so as to achieve the cooling effect for each disc during grinding. At the same time, a drainage hole 111 is provided on the first frame 110 for discharging the coolant ejected from the universal bamboo tube.

[0038] Continue to refer to Figure 2 It can be understood that the rotating bearing fixture 121 includes a first bearing frame 122, a rotating cylinder 123, a bearing bracket 124, a second bearing frame 125, an ejection cylinder 126 and a connecting rod 127.

The top of the second bearing frame 125 is connected to the bearing bracket 124. The bearing bracket 124 is used to place the disc. An ejection channel is provided in the bearing bracket 124. The connecting rod 127 is arranged in the ejection channel. The ejection cylinder 126 is arranged in the second bearing frame 125. The driving end of the ejection cylinder 126 passes through the top of the second bearing frame 125 and is connected to the bottom of the connecting rod 127. A second carrier frame 125 is provided between the rotating cylinder 123 and the carrier bracket 124, and an ejection cylinder 126 is provided in the second carrier frame 125. When the rotating cylinder 123 is working, it drives the second carrier frame 125, the ejection cylinder 126 and the carrier bracket 124 to rotate at the same time. After the grinding is completed, the ejection cylinder 126 drives the connecting rod 127 to rise in the ejection channel of the carrier bracket 124 until it contacts the disc, and ejects the grinded disc from the top of the carrier bracket 124.

[0039] Reference Figure 3It can be understood that the polishing table mechanism 100 also includes a polishing skin replacement component 130, and the polishing skin replacement component 130 includes a replacement bracket 131, a plurality of silos 132 and an upper cylinder 133 corresponding to the silo 132. The replacement bracket 131 is arranged on the first frame 110, and a plurality of silos 132 are arranged at intervals on the replacement bracket 131. The silo 132 is used to place new polishing skins, and the upper cylinders 133 are respectively arranged in the replacement bracket 131 corresponding to the upper cylinders 133, and the driving end of the upper cylinder 133 passes through the replacement bracket 131 and the silo 132, and is offset against the new polishing skin in the silo 132. In order to achieve a good grinding effect, the grinding head assembly 330 needs to replace the grinding skin on the grinding head after grinding several discs. The grinding skin replacement assembly 130 is provided to automatically replace the grinding skin on each grinding head, thereby improving the quality and efficiency of disc grinding.

[0040] Reference Figure 4, it can be understood that the material moving structure 230 includes a loading robot arm 231, a connecting component 232, a driving member 233, a guide plate 234 and a picking component 235, the driving end of the loading robot arm 231 is connected to the connecting component 232, the driving member 233 is arranged at the upper end of the connecting component 232, and the driving end of the driving member 233 is connected to the guide plate 234 to drive the guide plate 234 to move along the first direction, the guide plate 234 is provided with a plurality of guide holes 234a, the interval between the first end of the guide hole 234a and the first end of the adjacent guide hole 234a is greater than the interval between the second end of the guide hole 234a and the second end of the adjacent guide hole 234a, the number of the picking components 235 matches the number of the guide holes 234a, and the plurality of the picking components 235 can be slidably arranged at the lower end of the connecting component 232 along the second direction and inserted into the corresponding guide holes 234a, and the first direction and the second direction are perpendicular to each other. The loading robot arm 231 drives the picking assembly 235 to move to the position of the feeding structure 220 through the connecting assembly 232, and the driving member 233 drives the guide plate 234 to move in the first direction, and each picking assembly 235 is inserted into the corresponding guide hole 234a. When the position of the guide plate 234 changes, the position of each picking assembly 235 in the guide hole 234a changes accordingly. Since the guide holes 234a are arranged with one end close to the other end and divergent, in order to adapt to the guide holes 234a, the picking assembly 235 moves along the first direction. The pick-up components 235 slide in two directions, so as the position of each pick-up component 235 in the guide hole 234a changes, the intervals between adjacent pick-up components 235 will change, so that the intervals between the pick-up components 235 can be changed according to the different parts to be polished or the different first material tray 221 to adapt to taking out the disc from the first material tray 221, and the position where the pick-up component 235 places the disc can be adjusted according to different grinding machine materials, thereby improving the practicality of the loading mechanism 200 and the loading efficiency of the disc, thereby improving the overall processing efficiency of the product.

[0041] Specifically, the connecting assembly 232 includes a connecting block and two connecting plates. The upper end of the connecting block is aligned with the robotic arm, and the two connecting plates are respectively disposed on opposite sides of the connecting block. Two retrieving structures are provided, one on each of the corresponding connecting plates. A guide rail is provided at the lower end of the connecting plate along the second direction, and the retrieving assembly 235 is connected to the guide rail via a slider. The retrieving assembly 235 includes an L-shaped support block 342, a material suction nozzle, and a screw. The L-shaped support block 342 is connected to the guide rail via a slider. The material suction nozzle is disposed on the L-shaped support block 342, and the screw is inserted into the L-shaped support block 342. The screw nut can be slidably disposed in the corresponding guide hole 234a.

[0042] Reference Figure 5It can be understood that the feeding structure 220 also includes a first support frame 222, and the first material tray 221 is placed on the first support frame 222. First limiting fixing blocks 223 are provided at three corner positions of the first support frame 222, and a first clamping module 224 is provided at the fourth corner position of the first support frame 222. The first clamping module 224 is used to approach or move away from the direction of the first material tray 221, and cooperate with the first limiting fixing block 223 to fix the position of the first material tray 221. Specifically, the first limiting fixing block 223 is in the shape of a 7, which is used to clamp the three corners of the first material tray 221 to pre-position the first material tray 221. After the first material tray 221 is placed by the three first limiting fixing blocks 223, the first clamping module 224 is started to approach the direction of the first material tray 221, thereby holding the first material tray 221 to achieve the fixation of the first material tray 221, so as to prevent the grasping mechanism from grasping the disc at the first material tray 221 due to the shaking of the first material tray 221 itself, which may cause the disc to be not accurately absorbed, thereby affecting the loading efficiency.

[0043] Reference Figure 1 It can be understood that the loading mechanism 200 also includes a material receiving structure 240, which is arranged on the side of the feeding structure 220. The material receiving structure 240 includes a second material tray and a second support frame. The second material tray is placed on the second support frame. Second limiting blocks are provided at three corners of the second support frame. A second clamping module is provided at the fourth corner of the second support frame. The second clamping module is used to move toward or away from the second material tray and cooperate with the second limiting block to fix the position of the second material tray. When the grinding head mechanism 300 completes grinding the disc, the picking assembly 235 grabs the disc again and drives the loading robot arm 231 to place the disc on the second material tray in turn. The driving member 233 can adjust the position of the guide plate 234 according to the specifications of the second material tray to change the interval between each picking assembly 235, thereby placing the polished disc at the specified position.

[0044] It is understood that the loading mechanism 200 also includes a positioning mechanism, which includes a third support frame provided with a plurality of positioning protrusions that mate with the recessed portions of the discs. After the pick-up assembly 235 picks up a disc from the first tray 221, it first positions the disc on the positioning protrusions for positioning. Once positioned, the driver 233 adjusts the position of the guide plate 234 so that the spacing between two adjacent pick-up assemblies 235 is equal to the spacing between two adjacent positioning protrusions on the third support frame, accurately picking up each disc.

[0045] Reference Figure 6It is understood that the grinding head assembly 330 includes a connecting frame 331, a rough grinding assembly 332, and a fine grinding assembly 333. The connecting frame 331 is connected to the drive end of the grinding robot arm 320, and the rough grinding assembly 332 and the fine grinding assembly 333 are respectively connected to the two sides of the connecting frame 331. The rotation direction of the grinding heads of the rough grinding assembly 332 and the fine grinding assembly 333 is opposite to the rotation direction of the rotating support fixture 121. Specifically, the connecting frame 331 is an isosceles right triangle. The drive end of the grinding robot arm 320 is connected to the hypotenuse of the connecting frame 331, and the rough grinding assembly 332 and the fine grinding assembly 333 are respectively arranged on the two right-angled sides of the connecting frame 331. After completing the rough grinding, the robotic arm only needs to perform a simple rotation operation to switch the rough grinding component 332 to the fine grinding component 333, thereby improving the efficiency of grinding. By first rough grinding the disc and then fine grinding it, the smoothness of the disc grinding is improved.

[0046] Continue to refer to Figure 6It can be understood that the grinding head mechanism 300 also includes a film tearing assembly 340, which includes a film tearing bracket 341, a support block 342, a clamping cylinder 343 and a waste basket 344. The film tearing bracket 341 is arranged on the second frame 210, and the support blocks 342 are provided with a plurality of them and are arranged at intervals on the film tearing bracket 341. A fixed clamping block 345 is provided on the top of each support block 342. The number of the clamping cylinders 343 corresponds to the number of the support blocks 342. Each of the clamping cylinders 343 is arranged on the corresponding support block 342. The driving end of the clamping cylinder 343 is provided with a movable clamping block 346. The clamping cylinder 343 is used to drive the movable clamping block 346 to move closer to or away from the fixed clamping block 345. Specifically, in an embodiment of the present application, the interval between two adjacent support blocks 342 is the same as the interval between adjacent grinding heads. The grinding robot arm 320 drives the coarse grinding assembly 332 or the fine grinding assembly 333 to move above the support block 342, and moves the grinding skin part of the grinding head to between the fixed clamping block 345 and the movable clamping block 346. The clamping cylinder 343 drives the movable clamping block 346 toward the fixed clamping block 345, thereby clamping the grinding skin. The grinding robot arm 320 moves upward again to leave the film tearing assembly 340, and the operation of tearing off the old grinding skin on the grinding head can be completed. At the same time, the clamping cylinder 343 drives the movable clamping block 346 away from the fixed clamping block 345 again, so that the clamped old grinding skin naturally falls off into the waste basket 344, completing the storage of the old grinding skin. By cooperating with the movable clamp 346 and the fixed clamp 345 on the clamping cylinder 343, the grinding skin on each grinding head is automatically torn off, and the grinding skin replacement component 130 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.

[0047] Reference Figure 7It is understood that two grinding table mechanisms 100 and two grinding head mechanisms 300 are provided, respectively. The two grinding table mechanisms 100 are located on either side of the loading mechanism 200, and the two grinding head mechanisms 300 are located on the sides of the two grinding table mechanisms 100. Two grinding support structures 120 are provided on the grinding table mechanism 100. Because the grinding time of a disc may be long, two grinding table mechanisms 100 and grinding head mechanisms 300 are provided to grind multiple discs simultaneously. The loading mechanism 200 is provided between the two grinding table mechanisms 100 to facilitate loading of the grinding support structures 120 of the grinding table mechanisms 100 on both sides, thereby reducing the waiting time of the loading mechanism 200 during disc grinding. There are two grinding bearing structures 120 on each grinding table mechanism 100. When the grinding head mechanism 300 completes grinding the disc on one of the grinding bearing structures 120, the loading mechanism 200 can move to the other grinding bearing mechanism and grind the disc on the other grinding bearing structure 120 before it has time to remove the polished disc, thereby improving the grinding efficiency of the disc.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
