Fig. 2 is a schematic structural diagram of the goods fetching robot after taking out the material box provided in the first embodiment of the present application, fig. 3 is a schematic structural diagram of the goods fetching robot in the goods fetching box process provided in the first embodiment of the present application, as shown in fig. 2 and fig. 3, the goods fetching device includes a clamping component 21 and a turnover component 20, the clamping component 21 includes at least one retractable clamping mechanism, the clamping mechanism is disposed opposite to the turnover component 20, and the clamping mechanism is retractable with respect to the goods shelf 200 to fetch the material box 100 in the goods shelf 200, the turnover component 20 has two fixing positions for placing the material box 100, the two fixing positions are disposed on two opposite sides of the turnover component 20 respectively, and the turnover component 20 can turn over the two fixing positions in a vertical plane to make the two fixing positions face the goods fetching ports of the goods shelf 200 respectively.

It should be noted that, when the goods taking robot 1 performs the goods taking operation, the holding component 21 may be utilized to sequentially take out the plurality of material boxes 100 from the shelf 200, when taking out one material box 100, the material box 100 may be fixedly placed on the fixing position facing the goods taking opening at present, the other empty fixing position is located on one side of the overturning component 20 departing from the goods taking opening, after that, the overturning component 20 may overturn to overturn the fixing position on which the material box 100 is fixed to the side departing from the goods taking opening, and correspondingly overturn the empty fixing position to the goods taking opening, at this time, the holding component 21 may take out another material box 100 again, and fix the material box 100 on the empty fixing position, so that the plurality of material boxes 100 may be respectively fixed on different fixing positions of the overturning component 20, so that the goods taking robot 1 may carry and transport the plurality of material boxes 100 in one goods taking task, the logistics efficiency is improved.

It can be seen that the picking operation of the picking robot 1 is mainly performed by the flipping module 20 and the holding module 21, and specific structures of the flipping module and the holding module will be described in detail below.

As an optional embodiment, the flipping unit 20 may include a flipping table 202, the flipping table 202 is connected to the robot body 10 through a rotating shaft 203, two opposite side surfaces of the flipping table 202 are respectively provided with a fixing structure 201, and the two fixing structures 201 may respectively form two fixing positions, so that the material box 100 taken out by the clamping unit 21 may be fixed through the fixing structures 201.

Since the material box 100 is placed downward on the fixed position when the clamping assembly 21 takes out the material box 100, and the material box 100 may slip off from the fixed position under the action of gravity during the rotation of the overturning platform 202, the fixing structure 201 needs to ensure the complete fixation of the material box 100 and the overturning platform 202, which will be exemplified by different fixing structures 201.

As an optional implementation manner of the fixing structures 201, each fixing structure 201 may include two fixing members, the two fixing members are respectively located at the edge of the same side of the overturning platform 202, and the two fixing members can open and close relatively to fix the material tank 100, so as to ensure the stability of the material tank 100 during the overturning process of the overturning assembly 20.

Taking the fixing member on one side of the flipping table 202 as an example, when the two fixing members are opened, that is, the two fixing members move in the direction away from each other, at this time, the distance between the two fixing members is greater than the width of the material tank 100, so that the material tank 100 can enter between the two fixing members when the clamping assembly 21 takes out the material tank 100.

Alternatively, the fixing member may be disposed on the flipping table 202 through a sliding rail and may move along a length direction of the sliding rail to open and close, and the fixing member may be directly or indirectly driven by a motor or an air cylinder. For example, when a motor is used as a power source, a linear motor can be used for directly driving the fixing piece to move, or a rotary motor can be used for indirectly driving the fixing piece to move through a linear module or a screw nut; when the air cylinder is used as a power source, the output end of the cylinder rod of the air cylinder can be connected with the fixing piece so as to drive the fixing piece to move.

Alternatively, the clamp 212 may be any one of a hook, a clamp robot. When the clamping member 212 is a hook, a clamping structure matched with the hook needs to be arranged on the top or the side wall of the material box 100, and the hook can be matched with the clamping structure when being driven by the telescopic arm 211 to move to a position corresponding to the material box 100, so that the telescopic arm 211 can lift the material box 100 to move synchronously; when the clamping member 212 is a clamping manipulator, the clamping manipulator may be abutted against the sidewall of the material tank 100 to lift the material tank 100 by friction, or may be extended to the lower side of the rib of the sidewall of the material tank 100, and when the telescopic arm 211 retracts, the clamping manipulator is abutted against the rib, thereby lifting the material tank 100.

In addition, the clamping mechanism may further include a second driving unit, the telescopic arm 211 may include a fixed section 2111 and a moving section 2112, an output end of the second driving unit is connected to the moving section 2112, and the clamping member 212 is mounted at an end of the moving section 2112, so that the clamping member 212 is driven to move into and out of the shelf 200 by the movement of the moving end.

For example, the second driving unit may be a motor, and the motor may be installed on the fixed section 2111 and drive the moving section 2112 to move along the length direction of the screw in the form of a screw nut, thereby achieving extension and retraction.

Alternatively, there may be a plurality of moving sections 2112, and accordingly, the telescopic arm 211 has a multi-stage telescopic structure, so that when the material tank 100 is located at a deep position of the shelf 200, the telescopic arm 211 may have a sufficient length to extend into the interior of the shelf 200 to take out the material tank 100. The number of the moving sections 2112 and the maximum extension length of the telescopic arm 211 can be designed according to the depth of the storage space of the shelf 200, which is not particularly limited in this embodiment.

It should be noted that the telescopic arms 211 and the clamping members 212 may be arranged in pairs, that is, the two telescopic arms 211 may extend from two sides of the goods taking opening of the shelf 200, and the clamping members 212 may fix and take out the material box 100 from two sides of the material box 100, thereby ensuring stability of the material box 100 taking-out process.

Because the different fixed positions of the turnover assembly 20 face the goods taking opening, the clamping assembly 21 needs to perform one-time goods taking operation, so the clamping assembly 21 can also have different specific arrangement modes relative to the turnover assembly 20, and the following description will be given by two specific examples.
