[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figures 1 to 5 An embodiment of the grabbing type automatic unloading device for a polishing machine of the present invention is shown, comprising an unloading rack 1, a moving rack 2, a moving driving member 3 and a plurality of rows of grabbing mechanisms 4 for grabbing the polishing sheet on the polishing head, the unloading rack 1 is installed on the polishing machine, the moving rack 2 is slidably mounted on the unloading rack 1, each row of grabbing mechanisms 4 is installed on the moving rack 2, and the moving driving member 3 is installed on the unloading rack 1 and drives the moving rack 2 to drive the grabbing mechanism 4 to move to a position corresponding to the corresponding polishing head. When the polishing sheet on the polishing head needs to be replaced, the polishing machine is stopped, the moving driving member 3 is started, and the grabbing mechanism 4 is driven to move to a position corresponding to the corresponding polishing head, and then the grabbing mechanism 4 is operated to grab the polishing sheet on the polishing head to realize automatic unloading. Compared with the traditional structure, the unloading device realizes the automatic taking of the polishing sheet, has a simple structure, saves time and labor, and improves production capacity and efficiency; in addition, it avoids the erroneous operation of not taking the sheet when taking the sheet manually, and ensures the accuracy of taking the sheet.

[0025] In this embodiment, the moving driving member 3 is configured as a cylinder.

[0026] In this embodiment, the gripping mechanism 4 includes a gas source seat 41, a pair of slide seats 42, and a clamping claw 43 installed on the slide seat 42. The gas source seat 41 is fixed on the mobile frame 2 and is connected to the external gas. The pair of slide seats 42 are slidably mounted on the gas source seat 41 and drive the clamping claw 43 to clamp and grasp the polishing sheet on the polishing head. In this structure, the gas introduced will drive the clamping claw 43 to close along the slide seat 42 to achieve the clamping and grasping action of the polishing sheet. When the clamping claw 43 is unfolded along the slide seat 42, the polishing sheet is released and the polishing sheet falls, thereby realizing the automatic unloading of the material by gripping.

[0027] In this embodiment, a protective cover 5 for covering the moving frame 2, the moving drive member 3 and the grabbing mechanism 4 is installed on the unloading frame 1. The protective cover 5 plays a protective role on the moving frame 2, the moving drive member 3 and the grabbing mechanism 4.

[0028] In this embodiment, the protective cover 5 is provided with an escape hole 51 for the extension of the clamping claw 43. The escape hole 51 can ensure that the clamping claw 43 is extended to achieve the clamping and grasping action.

[0029] In this embodiment, a water baffle plate 6 for sealing the avoidance hole 51 is installed on the protective cover 5, and the clamping claw 43 is penetrated on the water baffle plate 6. The water baffle plate 6 seals the avoidance hole 51 to prevent external cooling water and dirt from entering the protective cover 5 from the avoidance hole 51.

[0030] In this embodiment, the protective cover 5 is also provided with a stopper 7 for driving the polishing sheet on the clamping jaw 43 to peel off. When the movable driving member 3 drives the clamping jaw 43 to retract, the polishing sheet will hit the stopper 7, thereby driving the polishing sheet on the clamping jaw 43 to peel off, and the structure is simple and ingenious.

[0031] In this embodiment, a track 11 is provided on the unloading rack 1, and the moving rack 2 is slidably mounted on the track 11. The provision of the track 11 ensures the smoothness of the moving rack 2 when moving.
