Please refer to FIG. 1, which is a perspective view of an embodiment of the sandpaper installation device of the present invention. The sandpaper installation device includes a first stage 100, a second stage 200, and a roller 300. The first stage 100 includes a first suction surface 110 having a plurality of suction holes 111. The second stage 200 is a working platform of the grinding equipment. The roller 300 includes a second adsorption surface 310 having a plurality of adsorption holes 311, and the second adsorption surface 310 is disposed on the circumferential surface of the roller 300.

As shown in Figure 1, in the sandpaper installation device of the present invention, the first stage 100 and the second stage 200 are guided by the motion of the ball screw, linear slide, rack and pinion mechanism, and the roller 300 is also guided by the movement of the bearing. Therefore, the first stage 100 and the second stage 200 can move in the first direction 710 or the second direction 720, and the roller can move around the axial direction 320 of the roller 300 and along the first rotation direction 730 or It is the second rotation direction 740 rotation.

Please refer to FIG. 2, which is a schematic structural diagram of the sandpaper 400 applicable to the sandpaper installation device of the present invention. The sandpaper 400 is adhesive-backed sandpaper suitable for sticking to the working platform of the grinding equipment; therefore, the sandpaper 400 includes a main body 410, a grinding surface 411 on the upper and lower surfaces of the main body 410, and a backing surface 412, and a backing surface 412 attached to the backing glue Surface 412 of the release paper 420.

Please refer to FIG. 3, which is a flowchart of the sandpaper installation method of the present invention. The sandpaper installation device can automatically tear off the release paper 420 from the sandpaper 400 through the sandpaper installation method of the present invention, and attach it to the On the second stage 200.

As shown in Fig. 3, the sandpaper installation method includes steps S1 to S5. First, in step S1, the first stage 100 adsorbs the sandpaper. Please refer to Figure 1 and Figure 4. Fig. 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 carrier 100 with one side of the release paper 420. The adsorption holes 111 on the first adsorption surface 110 continue to generate negative pressure. With the effect of atmospheric pressure, the first adsorption surface 110 will adsorb the release paper 420 of the sandpaper 400, so that the first carrier 100 carries The sandpaper 400.

Next, in step S2, as shown in FIGS. 1 and 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 FIGS. 1 and 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 The adhesive surface 412 of the sandpaper 400 is separated from the release paper 420 to expose the adhesive surface 412 of the sandpaper 400. The roller 300 rotates along the first rotation direction 730. At the same time, the adsorption holes 311 on the second adsorption surface 310 continue to generate negative pressure, and with the action of atmospheric pressure, the second adsorption surface 310 of the roller 300 will adsorb the grinding surface 411 of the sandpaper 400.

In order to ensure that when the sandpaper 400 moves on the first stage 100 and the roller 300 rotates, the main body 410 of the sandpaper 400 does not produce wrinkles, as shown in FIG. 4, the moving speed V _{1 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 closest to the first carrier 100 is also kept constant, and the speed _{between the velocity V 1} and the velocity V ₂ is controlled. The relative speed is 0. Thus, the sandpaper is interposed between the first stage 100 and the roller 300 400 V, and will not because of the different speeds of the first stage 100 of _one of the speed V ₂ of the roller 300 is subjected External force causes wrinkles.

It should be noted that in order to ensure that the first adsorption surface 110 of the first stage 100 does indeed adsorb the release paper 420 of the sandpaper 400 and the second adsorption surface 310 of the roller 300 does indeed adsorb the grinding surface of the sandpaper 400 411, and the adhesive surface 412 of the sandpaper 400 is 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 The adhesion force between the back adhesive surface 412 of the sandpaper 400 and the release paper 420 is greater than that.

In addition, in order to make the second suction surface 310 of the roller 300 completely adsorb the grinding surface 411 of the sandpaper 400, as shown in FIGS. 1 and 2, the length L of the second suction surface 310 of the roller 300 is shown in FIG. _{2 It is} designed to be greater than or equal to the length L _{1 of} the sandpaper 400. In this way, after the 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 back adhesive surface 412 of the sandpaper 400 is completely separated from the release paper 420, and the main body 410 of the sandpaper 400 is smoothly adsorbed on the second suction surface 310 of the roller 300 without wrinkles, the sandpaper 400 Then, the first stage 100 is transferred to the roller 300.

Please refer to Fig. 1 and Fig. 5 in step S4 of this sandpaper mounting method. Fig. 5 is a schematic diagram of the second state of the sandpaper installation device of the present invention. When the first stage 100 is far away from the roller 300, the second stage 200 moves toward the roller 300, and the second stage 200 contacts the adhesive surface 411 of the sandpaper 400. The second stage 200 moves in the second direction 720, and the second stage 200 contacts the adhesive surface 412 of the sandpaper 400 adsorbed on the second adsorption surface 310 of the roller 300.

Subsequently, in step S5, as shown in FIGS. 1 and 5, when the roller 300 continues to rotate and the second stage 200 continues to move, the adhesive surface 411 of the sandpaper 400 is attached to the second stage 200. The roller 300 rotates along the second rotation direction 740, and as the second carrier 200 moves, the adhesive surface 412 of the sandpaper 400 on the roller 300 will stick to the second carrier 200.

In steps S4 and S5, the movement directions of the second carrier 200 and the roller 300 can be selected from the following two movement configurations according to production line requirements and space scheduling considerations.

The first movement configuration is shown in FIG. 1, the first direction 710 in which the first stage 100 moves is opposite to the second direction 720 in which the second stage 200 moves. In other words, the first stage 100 and the second stage 200 move face to face. In addition, in order to match the first direction 710 and the second direction 720 in opposite directions, the roller 300 rotates around the axial direction 320 of the roller 300 in two opposite rotation directions, the first rotation direction 730 and the second rotation direction. 740 rotation. In this way, in the sandpaper installation method, the first carrier 100 and the second carrier 200 are respectively located at the two ends of the sandpaper installation device, which facilitates the arrangement of the production line.

Please refer to FIG. 6 for the second movement configuration, which is a three-dimensional schematic diagram of another embodiment of the sandpaper installation device of the present invention. The second direction 720 is the same, and the second stage 200 continues the movement of the first stage 100 continuously. And, 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 The direction 740 is the same. When in order to improve the working 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 rotation direction 740.

In order to ensure that when the sandpaper 400 moves on the second stage 200 and the roller 300 rotates, the main body 410 of the sandpaper 400 does not produce wrinkles, as shown in FIG. 5, the moving speed of the second stage V _{3 is} maintained Constant, the angular velocity of the rotation of the roller 300 also remains constant, that is, the tangential velocity V ₂ ′ of the roller 300 closest to the second carrier 200 is also kept constant, and the speed V ₃ and the velocity V ₂ ′ are controlled. The relative speed between time is zero. In this way, the sandpaper 400 between the second carrier 200 and the roller 300 will not be affected by the difference between the speed V _{3 of} the second carrier 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 surface 412 of the sandpaper 400 is indeed attached to the second stage 200, and the grinding surface 411 of the sandpaper 400 is indeed separated from the second adsorption surface 310 of the roller 300, the The adhesion force between the adhesive surface 412 of the sandpaper 400 and the second stage 200 is greater than the adhesion 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 surface 412 of the sandpaper 400 is smoothly attached to the second carrier 200, After no wrinkles are generated, the sandpaper 400 is transferred to the second carrier 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 carrier 200 via the first carrier 100 and the roller 300, without the need for the sandpaper in the grinding equipment. The grinding product is unloaded.

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 the production line requirements or energy consumption requirements, etc. .

The roller 300 is matched with a power source such as a motor and a stepping motor to drive the roller 300 to rotate.

In the second power source configuration, the first stage 100 and the second stage 200 are matched with a power source such as a motor to drive the first stage 100 and the second stage 200 to move. The roller 300 does not have a power source. By the adsorption force of the release paper 412 of the first carrier 100 and the sandpaper 400, the adsorption force of the roller 300 and the sandpaper surface 411 of the sandpaper 400, and the adhesive surface 412 of the sandpaper 400 and the second The adhesion force of the second stage 200, the roller 300 can rotate with the movement of the first stage 100 and the second stage 200 without a power source.

In the third power source configuration, the first stage 100 and the second stage 200 do not have power sources. The roller 300 is matched with a power source such as a motor and a stepping motor to drive the roller 300 to rotate. By the adsorption force of the release paper 412 of the first carrier 100 and the sandpaper 400, the adsorption force of the roller 300 and the sandpaper surface 411 of the sandpaper 400, and the adhesive surface 412 of the sandpaper 400 and the second The adhesion force of the second stage 200, the first stage 100 and the second stage 200 can move with the rotation of the roller 300 without a power source.
