[0084] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0085] See also Figure 1 The embodiment of the present application provides a screw driving device 100. The screw driving device 100 includes a feeding mechanism 10, a taking mechanism 20, a reversing mechanism 30, a discharging mechanism 40, a suction mechanism 50 and a screwdriver bit mechanism 60.

[0086] The feeding mechanism 10 is used to provide screws (not shown). It can be understood that the feeding mechanism 10 can be a screw machine, and the screw machine provides screws with nuts facing upwards.

[0087] The material taking mechanism 20 includes a material taking channel 21, one end of which corresponds to the feeding mechanism 10, so that the one end of the material taking channel 21 can suck in the screws provided by the feeding mechanism 10. In this embodiment, the material taking channel 21 can be a hose. In other embodiments, the material taking channel 21 can also be a hard tube. It can be understood that in this embodiment, the screw driving device 100 also includes a bottom plate 70, and the feeding mechanism 10 and the material taking mechanism 20 are adjacently arranged on the bottom plate 70.

[0088] The reversing mechanism 30 includes a movable reversing member 31, one end of which is connected to an external air source (not shown) to generate negative pressure and positive pressure in the reversing member 31, that is, the interior of the reversing member 31 can switch between positive pressure and negative pressure under the action of the external air source, and the other end of the reversing member 31 corresponds to the other end of the material taking channel 21 in the first position. The first position can be seen in FIG. Figure 3 The reversing member 31 is roughly located at a position where, when the other end of the reversing member 31 is in the first position and is correspondingly connected to the other end of the material taking channel 21, the material taking channel 21 sucks the screw on the feeding mechanism 10 under the negative pressure of the reversing member 31 and transmits the screw to the reversing member 31. It can be understood that when the screw is transmitted in the material taking channel 21, the nut of the screw is in front.

[0089] The discharge mechanism 40 includes a discharge channel 41 and a movable transfer table 42. One end of the discharge channel 41 corresponds to the transfer table 42 and is located above the transfer table 42. The reversing member 31 moves from the first position to the second position so that the other end of the reversing member 31 corresponds to the other end of the discharge channel 41. The second position can be seen in FIG. Figure 2 The reversing member 31 is roughly located in the position shown. When the reversing member 31 is in the second position and is connected to the other end of the discharge channel 41, the reversing member 31 switches from negative pressure to positive pressure and blows the screw into the discharge channel 41 under the action of the positive pressure, and the screw is transferred to the transfer table 42 through the discharge channel 41. It can be understood that when the screw is transferred in the discharge channel 41, the nut of the screw is at the back, and when the screw is transferred to the transfer table 42, the nut of the screw is at the top. In this embodiment, the discharge channel 41 can be a hose, and in other embodiments, the discharge channel 41 can also be a hard tube. The inner diameters of the feeding channel 21 and the discharge channel 41 are slightly larger than the diameter of the nut of the screw to ensure that the screw can be accurately transferred. It can be understood that the first position and the second position can be interchanged.

Under the negative pressure of the reversing member 31, the material taking channel 21 sucks the screw on the feeding mechanism 10 and transmits the screw to the reversing member 31 through the material taking channel 21. When the screw is sucked by the reversing member 31, the reversing member 31 moves to the second position with the screw (please refer to Figure 2 ) so that the other end of the reversing member 31 corresponds to the other end of the discharge channel 41, the reversing member 31 switches to positive pressure and blows the screw into the discharge channel 41 under the action of the positive pressure and transmits the screw to the transfer table 42 through the discharge channel 41. When the screw falls into the transfer table 42, the transfer table 42 moves with the screw to the bottom of the suction member 51, and the suction member 51 moves close to the transfer table 42 below it to absorb the screw. After the suction member 51 absorbs the screw, the suction member 51 moves away from the transfer table 42 with the screw, and the transfer table 42 resets and moves to a position corresponding to one end of the discharge channel 41. The feeding mechanism 10 and the material taking mechanism 20. The reversing mechanism 30 and the discharging mechanism 40 cooperate to make the screw fall onto the turntable 42 again. When the suction member 51 takes the screw away from the turntable 42 and the turntable 42 is reset, the screwdriver bit mechanism 60 is movably arranged in the suction member 51 to assemble the screw and rotate with the screw to perform the screw driving operation. After the screw driving operation, the screwdriver bit mechanism 60 is reset, the turntable 42 moves to the bottom of the suction member 51 and the suction member 51 approaches the turntable 42 again, so that the suction member 51 absorbs the screw again, so that the screwdriver bit mechanism 60 is assembled with the screw again to perform the screw driving operation, and this cycle is repeated.

The material picking drive member 23 drives the mounting member 24 and one end of the material picking channel 21 to move close to the feeding mechanism 10, so that one end of the material picking channel 21 corresponds to the feeding mechanism 10. It can be understood that the material taking driving member 23 can also drive the mounting member 24 and one end of the material taking channel 21 to move away from the feeding mechanism 10, so as to leave space for screws for the feeding mechanism 10. In this way, by setting the specific structure of the above-mentioned material taking mechanism 20, one end of the material taking channel 21 can be close to and away from the feeding mechanism 10, so that the material taking channel 21 can transmit screws, and one end of the material taking channel 21 is fixed by the mounting member 24.

Among them, the reversing hole 313 can be, for example, a step hole, and the end of the reversing hole 313 facing the mounting seat 34 is adapted to the screw and can stop the screw. When the reversing member 31 sucks the screw into the reversing hole 313, the external air source can switch from negative pressure to positive pressure through the change of the air pressure value.
