Please refer to FIG. 1 and FIG. 4 . 4 is a schematic diagram of the first state of the sandpaper installation device of the present invention. The sandpaper 400 is placed on the first suction surface 110 of the first stage 100 with one side of the release paper 420 . The suction holes 111 on the first suction surface 110 continuously generate negative pressure, and with the action of atmospheric pressure, the first suction surface 110 will absorb the release paper 420 of the sandpaper 400 so that the first stage 100 can carry The sandpaper 400.

Next, in step S2 , as shown in FIG. 1 and FIG. 4 , the first stage 100 moves toward the roller 300 , and the grinding surface 411 of the sandpaper 400 contacts the roller 300 . The first stage 100 moves in the first direction 710 , and the second suction surface 310 of the roller 300 contacts the grinding surface 411 of the sandpaper 400 carried on the first stage 100 .

Subsequently, in step S3, as shown in FIG. 1 and FIG. 4 , when the roller 300 continues to rotate and the first stage 100 continues to move, the second adsorption surface 310 of the roller 300 adsorbs the grinding of the sandpaper 400 surface 411 , and the adhesive-backed surface 412 of the sandpaper 400 is separated from the release paper 420 to expose the adhesive-backed surface 412 of the sandpaper 400 . The roller 300 rotates along the first rotation direction 730 . At the same time, the suction holes 311 on the second suction surface 310 continuously generate negative pressure. With the action of atmospheric pressure, the second suction surface 310 of the roller 300 will absorb the abrasive surface 411 of the sandpaper 400 .

In order to ensure that the sandpaper 400 does not wrinkle when the first stage 100 moves and the roller 300 rotates, the main body 410 of the sandpaper 400 is not wrinkled, as shown in FIG. 4 , the moving speed V1 of the _first stage is maintained constant, the angular velocity of the rotation of the roller 300 is also kept constant, that is, the tangential velocity V ₂ of the roller 300 at the position closest to the first stage 100 is also kept constant, and the speed V ₁ and the speed V ₂ are controlled. The relative velocity is 0. In this way, the sandpaper 400 between the first stage 100 and the roller 300 will not be affected by the difference between the speed V ₁ of the first stage 100 and the speed V ₂ of the roller 300 External forces cause wrinkles.

It should be noted that, in order to ensure that the first adsorption surface 110 of the first stage 100 indeed adsorbs the release paper 420 of the sandpaper 400, the second adsorption surface 310 of the roller 300 indeed adsorbs the abrasive surface of the sandpaper 400 411 and the adhesive-backed surface 412 of the sandpaper 400 are indeed separated from the release paper 420 , the adsorption force of the first adsorption surface 110 of the first stage 100 and the adsorption force of the second adsorption surface 310 of the roller 300 It is greater than the adhesion force between the adhesive-backed surface 412 of the sandpaper 400 and the release paper 420 .

In addition, in order to make the second adsorption surface 310 of the roller 300 completely adsorb the grinding surface 411 of the sandpaper 400, as shown in FIG. 1 and FIG. 2 , the length L of the second adsorption surface 310 of the roller 300 in the present invention ₂ is designed to be equal to or greater than the length L ₁ of the sandpaper 400 . In this way, after step S3 of the sandpaper installation method of the present invention is completed, the sandpaper 400 can surround and be adsorbed on the roller 300 .

When the adhesive-backed surface 412 of the sandpaper 400 is completely separated from the release paper 420, and the main body 410 of the sandpaper 400 is flatly adsorbed on the second adsorption surface 310 of the roller 300 without wrinkles, the sandpaper 400 Then it is transferred from the first stage 100 to the roller 300 .

For the second movement configuration, please refer to FIG. 6 , which is a three-dimensional schematic view of another embodiment of the sandpaper installation device of the present invention, the first direction 710 of the movement of the first stage 100 and the movement of the second stage 200 The second direction 720 is the same, and the second stage 200 moves continuously following the first stage 100 . In addition, in order to match the first direction 710 and the second direction 720 in the same direction, the roller 300 rotates in a single rotation direction around the axial direction 320 of the roller 300 , that is, the first rotation direction 730 and the second rotation Direction 740 is the same. In order to improve the operation efficiency of the sandpaper installation device, a plurality of the first stage 100 and a plurality of the second stage 200 can be used to move continuously, and the roller 300 does not need to frequently switch the first rotation direction 730 and the second rotational direction 740 .

In order to ensure that the sandpaper 400 does not wrinkle when the second stage 200 moves and the roller 300 rotates, the main body 410 of the sandpaper 400 is not wrinkled, as shown in FIG. 5 , the moving speed _V3 of the second stage is maintained is constant, the angular velocity of the rotation of the roller 300 is also kept constant, that is, the tangential velocity V ₂ ′ of the roller 300 at the position closest to the second stage 200 is also kept constant, and the speed V ₃ and the speed V ₂ ′ are controlled to be constant. The relative velocity between them is 0. In this way, the sandpaper 400 between the second stage 200 and the roller 300 will not be affected by the difference between the speed V ₃ of the second stage 200 and the speed V ₂ ′ of the roller 300 Wrinkles caused by external force.

It should be noted that, in order to ensure that the adhesive-backed surface 412 of the sandpaper 400 is indeed attached to the second stage 200 and that the abrasive surface 411 of the sandpaper 400 is indeed separated from the second adsorption surface 310 of the roller 300, the The adhesive force of the adhesive-backed surface 412 of the sandpaper 400 and the second stage 200 is greater than the adsorption force of the second adsorption surface 310 of the roller 300 .

When the grinding surface 411 of the sandpaper 400 is completely separated from the second adsorption surface 310 of the roller 300 , and the main body 410 of the adhesive-backed surface 412 of the sandpaper 400 is flatly attached to the second stage 200 , After no wrinkles are generated, the sandpaper 400 is transferred to the second stage 200 by the roller 300 .

After step S5 of the sandpaper installation method of the present invention is completed, the sandpaper 400 is automatically installed on the second stage 200 via the first stage 100 and the roller 300 without the need to be Abrasive products are removed.

The first carrier 100 , the second carrier 200 , and the roller 300 of the sandpaper installation device of the present invention also include a plurality of power sources, and the following three power source configurations can be selected according to production line requirements or energy consumption requirements, etc. .
