[0049] In addition, in order to process the debris generated during polishing, a dust cover 30 can be installed outside the large abrasive cloth wheel 27 and the small abrasive cloth wheel 28, a dust suction port 31 is formed on the installation base plate 16, the dust suction port 31 is located between the two first rails 29, and a dust suction nozzle cover 32 is installed below the dust suction port 31 on the installation base plate 16, the dust suction nozzle cover 32 is connected with a negative pressure suction device, and the debris generated during polishing is timely sucked away through the dust suction port 31 through the negative pressure effect.

It should be noted that in the embodiment, five groups of screw edging mechanisms 17 are used to polish five metal discs synchronously, and more groups of screw edging mechanisms 17 can also be provided to polish more metal discs synchronously, for example, ten groups of screw edging mechanisms 17 can be provided, and the number of clamping assemblies 10, the number of first vacuum pads 23 and the number of second vacuum pads 61 are correspondingly changed, so that ten metal discs can be polished at one time.

[0051] As shown in Figure 6 and Figure 7 The jacking mechanism of the embodiment is used for reciprocating lifting of the jacking plate 7, and the specific structure is that a camshaft 33 is rotatably installed on the fixed plate 6, two cams 34 are installed on the camshaft 33, the bottom of the jacking plate 7 is provided with two groups of supports 35, a ball bearing 36 is rotatably installed on each group of supports 35, the two cams 34 correspond to the two groups of supports 35 respectively, and the ball bearing 36 on the support 35 is in contact with the outer edge of the corresponding cam 34; the end of the camshaft 33 is provided with a driven sprocket 37;

The camshaft 33 starts to rotate, and the cam 34 is always in contact with the ball bearing 36. Due to the special structure of the cam 34, the distance between the ball bearing and the axis of the camshaft 33 changes when the cam 34 rotates, and finally the jacking plate 7 moves up and down reciprocally.

[0054] The two groups of opposite motion clamping mechanisms of the embodiment are used for driving the two movable rails 5 to move reciprocally, and the specific structure is that the opposite motion clamping mechanism includes two second line rails 40 and two lead screws 41.

[0055] One of the movable rails 5 is installed on the first slide plate 44 of the two groups of opposite motion clamping mechanisms, and the other movable rail 5 is installed on the second slide plate 45 of the two groups of opposite motion clamping mechanisms.

[0056] The clamping motor drives the two lead screws 41 to rotate synchronously, so that the first slide plate 44 and the second slide plate 45 move on the corresponding lead screws. Since the threads on the two lead screws 41 are opposite in rotation direction, the moving directions of the first slide plate 44 and the second slide plate 45 are opposite. One of the two movable rails 5 is installed on the first slide plate 44, and the other movable rail 5 is installed on the second slide plate 45. The moving directions of the two movable rails 5 are opposite. When facing the movement, the clamping assembly 10 can clamp the metal disc.

The two fourth linear rails 56 are slidingly installed with a sliding seat 57 on which a vertical moving motor 58 is installed. The vertical moving motor 58 is provided with a gear on the main shaft which is engaged with the vertical rack 55. The sliding seat 57 is also installed with a cross arm 60 which is provided with five second vacuum suction cups 61 on the bottom surface in intervals. The five second vacuum suction cups 61 correspond to the five sets of clamping assemblies 10.

[0059] One set of disc grabbing mechanism is used to transfer the metal discs clamped by the five sets of clamping assemblies 10 to the five first vacuum suction cups 23 of the edge grinding assembly 14. The other set of disc grabbing mechanism is used to transfer the metal discs on the five first vacuum suction cups 23 to the belt of the discharging conveyor belt assembly 15.

[0060] The moving process of the disc grabbing mechanism is as follows: the walking motor 53 drives the horizontal movement of the vertical square plate 52 through the engagement of the inclined gear 54 and the inclined rack 50. The vertical moving motor 58 drives the vertical movement of the sliding seat 57 through the engagement of the gear and the vertical rack 55.
