DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will be further described below in conjunction with specific embodiments.
[0020] As Figure 1 and 2 shown, the automatic feeding device for polishing the notebook shell of the present utility model includes a machine table 1, and a feeding station 2 and a polishing station 3 are provided on the machine table 1.
[0021] Among them, the feeding station 2 includes a liftable workbench 21, and a plurality of mounting grooves 22 that overlap each other and can engage notebook shells of different model sizes are formed on the front surface of the workbench 21. A plurality of limit plates 23 that can move back and forth in the horizontal plane are further provided on the front surface of the workbench 21. In this embodiment, there are a total of six limit plates 23, two of which are respectively located on both sides of the short side of the notebook shell, and the other four are respectively in two groups on both sides of the long side of the notebook shell. Thus, first, the staff can conveniently place the notebook shell to be polished into the workbench 21 through the mounting grooves 22, and then the limit plates 23 fix the notebook shell by moving back and forth. The design of the six limit plates 23 can improve the stability.
[0022] The polishing station 3 includes a polishing platform 31, and a mechanical gripper 32 is provided at the edge of the polishing platform 31. The mechanical gripper 32 includes a fixed upper gripper 321 and a liftable lower gripper 322, and the mechanical gripper 32 can independently rotate in the horizontal plane. Thus, when the notebook shell is fixed, the workbench 21 can rise to a suitable position, and then the mechanical gripper 32 is rotated, and the edge of the notebook shell can be engaged between the upper gripper 321 and the lower gripper 322. By lifting the lower gripper 322, the notebook shell can be fixed to the mechanical gripper 32, and then the mechanical gripper 32 rotates back to the polishing platform 31.
[0023] In addition, an anti - detachment protection device is further provided in the mechanical gripper 32, which includes a contact sensor 35 provided in the upper gripper 321 and a normally - closed safety lock 36 provided in the lower gripper 322. A pressure relay 323 and a solenoid valve 324 are also provided in the lower gripper 322.
[0024] When the contact sensor 35 senses contact with the notebook housing, the solenoid valve 324 is in a normally open state, the pressure relay 323 is in a non-pressure state, and no electrical signal is emitted. When the contact sensor 35 senses the loss of contact with the notebook housing, the solenoid valve 324 closes, the pressure relay 323 emits a signal, and the integrated controller controls the safety lock 36 to open after receiving the electrical signal. The safety lock 36 extends from the left and right sides of the lower gripper 322 to support the notebook housing. Thus, when the lower gripper 322 fails to clamp and fix the notebook housing due to a fault or short circuit or other reasons, since the notebook housing is separated from the upper gripper 321, the safety lock 36 will open, quickly support the unfixed notebook housing, and prevent it from falling to reduce the yield rate.
[0025] A linear conveying track 33 is also provided on the grinding platform 31 and the track 33 can convey in both forward and reverse directions. A turntable 34 that can rotate independently in the horizontal plane is provided on the track 33. Several grinding discs 37 are also provided directly above the track 33. Four grinding discs 37 are arranged in sequence along the conveying direction of the track 33 and can respectively grind one side of the notebook housing.
