In one embodiment, the suction device 1 further includes a first moving position sensor 171 and a first moving sensing member 172, the first moving position sensor 171 is disposed on the slide block 12, the first moving sensing member 172 is connected to the driving shaft 131, and the first moving sensing member 172 corresponds to the first moving position sensor 171, the first moving position sensor 171 has a first light source generating portion 1711, the first moving sensing member 172 has a first moving light shielding sheet 1721, and the first moving light shielding sheet 1721 is movable in the first light source generating portion 1711.

Furthermore, the first movement sensing element 172 further has a limiting guide rod 1722, one end of the limiting guide rod 1722 is fixed to the first movement sensing element 172, and the other end of the limiting guide rod 1722 is movably disposed on the sliding block 12, so that the movement stroke of the first movement position sensor 171 is affected by the limiting guide rod 1722.

When the first movable shade 1721 of the first movable sensing element 172 moves toward the first light source generating portion 1711, the range of movement of the first movable sensing element 172 toward the first light source generating portion 1711 is limited by the fixing protrusion 123 and is also limited by the first movable position sensor 171. When the first movable light shielding sheet 1721 of the first movable sensing element 172 moves away from the first light source generating portion 1711, the first movable sensing element 172 drives the limiting guide rod 1722 to move in a direction away from the fixing protrusion 123, and the stopping element 1723 at the other end of the limiting guide rod 1722 is clamped by the fixing protrusion 123, so that the moving range of the first movable sensing element 172 is limited by the fixing protrusion 123.

When the moving assembly 13 drives the suction nozzle 15 to move downwards through the slider 12, the first end 121 of the slider 12 moves to the bottom end of the slide 11, and the slider 12 stops moving downwards. At this time, the moving motor 132 continuously drives the driving shaft 131 to operate, the driving shaft 131 drives the first moving sensing member 172 to move toward the fixing protrusion 123, and the first moving shade 1721 moves toward the first light source generating portion 1711. When the first movable shading sheet 1721 enters the first light source generating portion 1711, the first movable shading sheet 1721 blocks the light source generated by the first light source generating portion 1711, and the first movable position sensor 171 generates the sensing signal at this time, the moving motor 132 stops operating according to the sensing signal, so as to prevent the moving motor 132 from continuously operating and preventing the slider 12 from separating from the slider 11. While preventing the moving assembly 13 from continuously moving the suction nozzle 15 downward to prevent the suction nozzle 15 from crushing the product. In addition, the arrangement of the first moving position sensor 171 and the first moving sensing member 172 prevents the moving motor 132 from stopping immediately when the end of the slider 12 away from the suction nozzle 15 moves to the bottom end of the slide 11, and stops the operation of the moving motor 132 within a certain buffering time after the end of the slider 12 away from the suction nozzle 15 moves to the bottom end of the slide 11, so as to increase the service life of the moving motor 132.

In one embodiment, the suction device 1 further includes a second moving position sensor 181 and a second moving sensing member 182, the second moving sensing member 182 is disposed on the sliding block 12, the second moving position sensor 181 is disposed on the frame body 10, and the second moving position sensor 181 corresponds to the second moving sensing member 182, the second moving position sensor 181 has a second light source generating portion 1811, the second moving sensing member 182 has a second moving light shielding sheet 1821, and the second moving light shielding sheet 1821 is movable in the second light source generating portion 1811. The second light source generating portion 1811 and the first light source generating portion 1711 have the same structure, and thus are not described again.

When the driving shaft 131 is driven by the moving motor 132 to move (i.e. move upwards) the driving shaft 131 away from the suction nozzle 15, the driving shaft 131 drives the slider 12 to ascend relative to the sliding base 11, and the slider 12 drives the second moving light shielding sheet 1821 of the second moving sensing element 182 to move toward the second light source generating portion 1811 of the second moving position sensor 181. When the second movable light-shielding sheet 1821 moves into the second light source generating portion 1811, the second movable light-shielding sheet 1821 blocks the light generated by the second light source generating portion 1811, so that the second moving position sensor 181 generates a sensing signal, and the moving motor 132 stops operating according to the sensing signal, thereby preventing the moving motor 132 from continuously driving the slider 12 to move upwards and collide with the frame body 10.

In one embodiment, the suction device 1 further includes a rotation sensor 191 and a rotation position sensor 192, the rotation sensor 191 is disposed at the other end of the rotation shaft 141, the rotation position sensor 192 is disposed on the slider 12, the rotation position sensor 192 corresponds to the rotation sensor 191, the rotation position sensor 192 has a third light source generating portion 1921, the rotation sensor 191 has a rotation shielding plate 1911, the rotation shielding plate 1911 has a sensing notch 1912, and the rotation shielding plate 1911 is rotatable in the third light source generating portion 1921.

Meanwhile, the rotating shaft 141 drives the rotation sensing member 191 to rotate, so as to drive the rotating shade 1911 to rotate. The sensing notch 1912 of the rotary shade 1911 corresponds to the third light source generator 1921, and the light generated by the third light source generator 1921 is not blocked by the rotary shade 1911, and at this time, the initial position of the suction nozzle 15, that is, the state where the suction nozzle 15 is not rotated, may be set. When the rotary motor 142 drives the rotary shade 1911 to rotate through the rotary shaft 141, the rotary shade 1911 enters the third light source generating portion 1921 and cuts off the light generated by the third light source generating portion 1921, and the rotary position sensor 192 can calculate the rotary stroke of the rotary shade 1911 according to the time when the light is cut off, so as to know the rotary angle of the suction nozzle 15. Before the suction nozzle 15 re-sucks the product, the suction nozzle 15 can be restored to the original position by the combination of the rotary shade 1911 and the rotary position sensor 192.
