[0002] Melamine (also known as phenalkamine) is a synthetic material with high strength and good heat resistance. It is usually made by the condensation reaction of phenol and aldehyde. It has a wide range of applications in industry and daily life. Melamine has excellent heat resistance and can remain stable in high temperature environments. It is not easy to deform or melt. This gives it a great advantage in the manufacture of heat-resistant plastics and refractory materials. At the same time, melamine material has high strength and hardness, allowing it to withstand high pressure and heavy load stress. Therefore, it is often used to manufacture daily utensils such as drinking cups.

After the melamine drinking cup is grabbed, the manipulator 200 drives the fixed jaws 210 to move to the polishing mechanism 300. The first polishing mechanism 300 Unit 310 grinds the outer wall of the melamine drinking cup. After the grinding is completed, the robot 200 drives the fixed clamping jaw 210 to move to the second grinding unit 320, and the second grinding unit 320 grinds the chamfers, handle, grooves of the handle, etc. of the melamine drinking cup. When the melamine drinking cup is polished, the robot 200 continues to drive the fixed clamping jaw 210 to move to the polishing mechanism 400, and the polishing mechanism 400 polishes the outer wall of the melamine drinking cup, thereby realizing the automated grinding and polishing of the melamine drinking cup, thereby reducing manual operation, reducing labor costs, and ensuring labor safety, while also improving the efficiency of grinding and polishing the melamine drinking cup.

[0033] The manipulator 200 in this embodiment is a six-axis manipulator, which can realize the movement of the melamine drinking cup through the six-axis manipulator, so that the melamine drinking cup can cooperate with the first grinding unit 310, the second grinding unit 320 and the polishing mechanism 400, and the melamine drinking cup can be changed in various positions during grinding and polishing, so that the melamine drinking cup can be better ground and polished.

[0034] In addition, in order to improve safety performance, a safety fence 500 is provided on the outer side of the loading and unloading mechanism 100, the manipulator 200, the grinding mechanism 300 and the polishing mechanism 400. The safety fence 500 can isolate the operator from the working range of the device, thereby ensuring the safety performance of the operator and achieving safe production.

[0035] See also Figure 3In order to realize automatic loading and unloading of melamine drinking cups, the loading and unloading mechanism 100 in this embodiment includes a mounting seat 110, a loading unit 120, a transfer unit 130 and a discharge channel 140. A slide rail 111 and a rodless cylinder 112 are provided on the mounting seat 110. The loading unit 120 is mounted on the mounting seat 110 and is located at one end of the slide rail 111. The transfer unit 130 is connected to the rodless cylinder 112 and the slide rail 111 respectively. The rodless cylinder 112 can drive the transfer unit 130 to move to the bottom of the loading unit 120. The discharge channel 140 is provided on one side of the mounting seat 110, and the loading unit 120 includes a support plate 121, a barrel 122 and a blocking rod 123. The support plate 121 is mounted on the mounting base 110 through the support pillar 124, the barrel 122 and the baffle 123 are respectively arranged on the support plate 121, and a limiting groove 125 is opened on the side wall of the barrel 122, the baffle 123 is connected to the driving cylinder 126, and the driving cylinder 126 can drive the baffle 123 to retract and retract, and the transfer unit 130 includes a transfer plate 131 and a positioning cylinder 132, the transfer plate 131 is respectively connected to the slide rail 111 and the rodless cylinder 112, the rodless cylinder 112 drives the transfer plate 131 to move along the slide rail 111, and a positioning groove 133 is provided on the transfer plate 131, and the positioning cylinder 132 is installed on the transfer plate 131 and connected to the positioning plate 134.

[0036] When loading melamine drinking cups, several stacked melamine drinking cups are placed in the barrel 122 of the loading unit 120, and the handles of the melamine drinking cups are placed in the limiting groove 125. The handles of the melamine drinking cups at the bottom of the barrel 122 are blocked by the blocking rod 123. When the melamine drinking cups need to be transported, the rodless cylinder 112 drives the transfer unit 130 to move to the bottom of the loading unit 120, and the driving cylinder 126 drives the blocking rod 123 to retract. The stacked melamine drinking cups in the barrel 122 slide downward and fall, and the melamine drinking cup at the bottom falls into the The transfer plate 131 is in the positioning groove 133, and there is a lifting cylinder under the positioning groove 133, which can drive the melamine drinking cup in the positioning groove 133 to move up and down. When the melamine drinking cup falls into the positioning groove 133, the driving cylinder 126 drives the blocking rod 123 to extend to block the cup handle of the melamine drinking cup above. The melamine drinking cup that falls into the positioning groove 133 moves downward under the drive of the lifting cylinder. After moving to the set position, the positioning cylinder 132 drives the positioning plate 134 to position the cup handle of the melamine drinking cup in the positioning groove 133, thereby preventing the melamine drinking cup from falling. The water cup will be displaced when it moves, ensuring that the subsequent fixed clamp 210 accurately grasps the position of it, which is convenient for grinding and polishing. After the melamine drinking cup is positioned, the rodless cylinder 112 drives the transfer plate 131 to move along the slide rail 111. After moving to the set position, the positioning cylinder 132 drives the positioning plate 134 to loosen the handle of the melamine drinking cup. The lifting cylinder lifts the melamine drinking cup in the positioning groove 133, and the manipulator 200 drives the fixed clamp 210 to grab the lifted melamine drinking cup. This cycle is repeated to realize automatic loading of the melamine drinking cup. When the manipulator 200 drives the fixed clamp 210 to grab the melamine drinking cup to the grinding mechanism 300 and the polishing mechanism 400 for grinding and polishing, the manipulator 200 will drive the fixed clamp 210 to place the polished melamine drinking cup into the unloading channel 140, and the melamine drinking cup is collected along the unloading channel 140, thereby realizing automatic loading and unloading of the melamine drinking cup to improve the efficiency of grinding and polishing of the melamine drinking cup. The loading and unloading mechanism 100 is a prior art, and for details, please refer to Chinese Patent: 202021036243.8.

The polishing belt 313 is sleeved on the rotating disk 314. The polishing motor 312 drives the rotating disk 314 to rotate, thereby rotating the polishing belt 313. The second polishing unit 320 includes a second base 321 and a floating spindle 322. The movable spindle 322 is mounted on the second base 321, and a grinding head 323 is provided on the movable spindle 322.

[0038] When the manipulator 200 drives the fixed jaw 210 to transfer the melamine drinking cup to the polishing mechanism 300, it will first be transferred to the first polishing unit 310. The polishing motor 312 of the first polishing unit 310 will drive the rotating disk 314 to rotate, and the rotating disk 314 will drive the polishing belt 313 to rotate. The polishing belt 313 polishes the side wall of the melamine drinking cup. After the polishing is completed, the manipulator 200 drives the fixed jaw 210 to transfer the melamine drinking cup to the polishing mechanism 300. 10 The melamine drinking cup is transferred to the second polishing unit 320. The floating spindle 322 of the second polishing unit 320 drives the grinding head 323 to rotate. The grinding head 323 polishes the chamfers, handle, and concave part of the handle of the melamine drinking cup, thereby realizing automatic polishing of the melamine drinking cup, thereby avoiding manual operation, reducing labor costs, and improving safety.

The melamine drinking cup is polished by the polishing wheels 430. In order to ensure the polishing effect of the melamine drinking cup, the polishing wheel 430 at one end is a hemp wheel, and the polishing wheel 430 at the other end is a cloth wheel. The hemp wheel and the cloth wheel can achieve different polishing effects on the melamine drinking cup. Finally, the automatic polishing of the melamine drinking cup is realized, manual operation is avoided, labor costs are reduced, and safety is improved.
