Preferably, the platform 200 is in a disc shape, and the rotating shaft 740 is fixed at the center of the platform 200.

When the tray 300 needs to rotate, the rotating motor 710 is started, and power is transmitted to the rotating shaft 740 through the transmission gear 730 to drive the bearing table 200 to rotate, so that the rotation of the tray 300 arranged on the bearing table 200 is realized. The arrangement of the rotary driving assembly 700 is convenient for layout and saves space.

In this embodiment, the rotation driving assembly 700 further includes a first worm 720 and a first worm wheel 750 engaged with the first worm 720, wherein the first worm 720 is fixedly connected with the output shaft of the rotation motor 710, and the first worm wheel 750 is located between the first worm 720 and the transmission gear 730.

Referring to fig. 9 and 10, in the present embodiment, the pickup device 030 may further include a plurality of supporting members 110 spaced apart from each other on the base frame 100, and the carrier table 200 is supported on the supporting members 110. Due to the arrangement, the bearing table 200 is supported, the load borne by the rotary driving assembly 700 is shared to a certain extent, and the stability of the bearing table 200 in the rotating process is ensured.

Preferably, the supporting member 110 includes a supporting column 111 and a ball 112 disposed in the supporting column 111, and an elastic member (not shown), the ball 112 is movably disposed in the supporting column 111, the elastic member is connected between the ball 112 and the base frame 100, and under the action of the elastic member, the ball 112 always has a movement tendency protruding from the supporting column 111, so that the ball 112 contacts with the lower surface of the carrier 200. The arrangement of the support member 110 in rolling contact with the carrier 200 reduces the resistance applied to the carrier 200 during the rotation process, so that the rotation process of the carrier 200 is smoother.

Preferably, the number of the supporting members 110 is three, and the three supporting members 110 are distributed in an isosceles triangle.

In this embodiment, the tray 300 may be horizontally moved by the electric push rod 410, but the present invention is not limited to this, and other arrangements may be adopted, as shown in fig. 11. Fig. 11 is a schematic structural view of another linear driving assembly of the pickup apparatus provided in this embodiment, referring to fig. 11, the linear driving assembly 400 includes a mounting base 460, a driving motor 420, a screw rod 430, and a nut 440 engaged with the screw rod 430, specifically, the mounting base 460 is disposed on the carrying platform 200, the driving motor 420 is disposed on the mounting base 460 and is in transmission connection with the screw rod 430, a mounting frame 441 is disposed on the nut 440, the tray 300 is fixedly connected with the mounting frame 441, and the linear driving assembly 400 further includes a guide rod 450 supported on the mounting base 460, wherein the guide rod 450 and the screw rod 430 both extend in a horizontal direction and are disposed in parallel to each other, a movable member 442 movably engaged with the guide rod 450 is disposed on the guide rod 450, and the mounting frame 441 is connected with the movable member 442.

The process of the linear driving assembly 400 for moving the tray 300 in the horizontal direction is as follows: the driving motor 420 is started to drive the screw rod 430 to rotate, and the nut 440 drives the mounting frame 441 to linearly reciprocate along the horizontal direction under the sliding limit of the movable piece 442 and the guide rod 450 and the screw transmission of the nut 440 and the screw rod 430. The linear driving assembly 400 has good transmission stability.

With continued reference to fig. 11, the linear driving assembly 400 may further include a second worm 480 and a second worm wheel 470, wherein the second worm 480 is fixedly connected to the output shaft of the driving motor 420, and the second worm wheel 470 is engaged with the second worm 480 to rotate the lead screw 430. With such an arrangement, the space occupation of the linear driving assembly 400 in the first horizontal direction can be saved, so that the structure of the article picking device 030 according to the embodiment is more compact. It should be noted that the linear driving assembly 400 may also be a gear and rack linear driving structure, or a transmission belt linear driving mechanism, and the description thereof is omitted in this embodiment.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
