The first conveyor 321 has a placing station 3211 and a transferring station 3212. The placing station 3211 is located at one end of the first conveyor belt 321, and is configured to place the transfer box tool 40 containing the empty component box for boxing. Transfer station 3212 is located at the other end of first conveyor belt 321.

Still be provided with first spacing sensor 35 on the support frame, this first spacing sensor 35 is corresponding with transport station 3212 to with first transmission driving motor communication connection, be used for instructing that the splendid attire has empty for the vanning transport box frock 40 of part case to be carried to transport station 3212 on. In the present embodiment, the first limit sensor 35 is located at a position directly in front of the first predetermined direction C. Specifically, when the distance between the sensing plate 451 of the transfer box tooling 40 and the first limit sensor 32 is a first predetermined distance, the first limit sensor 32 controls the first conveyor motor to stop rotating, so that the transfer box tooling 40 stops at the transfer station 3212.

The second transfer unit 33 is used to transfer the parts box for packing containing the acceptable weld nuts, which is carried on the transfer box tool 40 in this embodiment. The second transfer part 33 includes a second transfer belt 331 and a second transfer driving motor. The second conveying belt 331 extends horizontally along the length direction of the supporting frame, is a driving roller conveying belt, is connected with the second conveying driving motor and can perform conveying action along the second predetermined direction E under the driving of the second conveying driving motor.

The first conveyor belt 321 and the second conveyor belt 331 are disposed side by side and adjacent to each other. The upper surface of the first conveyor belt 321 and the upper surface of the second conveyor belt 331 are located at the same level, or the upper surface of the first conveyor belt 321 is higher than the upper surface of the second conveyor belt 331, but in the present embodiment, the upper surface of the first conveyor belt 321 and the upper surface of the second conveyor belt 331 are located at the same level.

The second conveyor belt 331 has a boxing station 3311. The packing station 3311 is located at one end of the second conveyor belt 331 and corresponds to the exit port 271 of the output lane, and in this embodiment, the packing station 3311 is located directly below the exit port 271 of the output lane. The boxing station 3311 and the transferring station 3212 are located on the same side of the support frame, and the boxing station 3311 and the transferring station 3212 are located on the same line and are arranged in close proximity. When the transfer box tooling 40 is located at the boxing station 3311, the upward opening of the boxing part box X just corresponds to the output passage outlet 271, so as to receive the qualified welded nuts output from the output passage outlet 271, and after the boxing operation is completed, the second conveyor belt 331 conveys the transfer box tooling 40 and the boxing part box X away from the boxing station 3311 along the second predetermined direction E.

The transfer assembly 34 is disposed on the supporting frame 31 and located on the same side of the supporting frame 31 as the transfer station 3212, and includes a second driving motor 341, a linkage belt 342, and a pushing member 343.

In this embodiment, the linkage belt 342 is a belt, is installed on the output shaft of the second driving motor 341, and is located above the first conveyor belt 321 and the second conveyor belt 331. The linkage belt 342 is in a U shape with an opening facing the transfer station 3212, and one end of the linkage belt 331 can horizontally move (along the width direction of the support frame 31) between the transfer station 3212 and the boxing station 3311 under the driving of the second driving motor 341.

Pusher 343 is attached to the movable end of linkage belt 342 and is movable with the movement of linkage belt 342 between transfer station 3212 and boxing station 3311. The pushing member 343 may be a vertically arranged long pushing plate or a vertically arranged clamping plate. In this embodiment, the pushing member 343 is a vertically disposed clamping plate having a T-shaped cross section. The size of grip block is still corresponding with transfer box frock 40's protruding portion 43 for when the grip block was located directly over transfer station 3212, the length direction's of protruding portion 43 both ends can be located the opening region of grip block, and then when the grip block moved along third predetermined direction D under the drive of linkage area, the grip block just can promote transfer box frock 40 and remove to vanning station 3311 from transfer station 3212.

The support frame is further provided with a second limit sensor (not shown in the figure), which corresponds to the boxing station 3311 and is in communication connection with the second driving motor 341, for indicating that the transfer box tool 40 containing the empty boxing part box is conveyed to the boxing station 3311. In this embodiment, the second limit sensor is located at a position directly in front of the third predetermined direction D.

Specifically, when the distance between the sensing plate 451 of the transfer box tooling 40 and the second limit sensor is a second predetermined distance, the second limit sensor controls the second driving motor 341 to stop, so that the transfer box tooling 40 stops at the boxing station 3311. At this time, the packing component box X on the transfer box tool 40 can receive the welded nut a as a qualified product dropped from the output port 271, that is, perform the packing operation. After the boxing is completed, the second conveyor belt 331 is driven by the second conveying driving motor to convey the transfer box tool 40 and the boxing part box X away from the boxing station 3311 along the second predetermined direction E. And when the transfer box tooling 40 leaves the box loading station 3311, the second driving motor drives the linkage belt 342 to move, so as to drive the pushing member 343 to move in the direction opposite to the third predetermined direction D, and then return to the corresponding position of the transfer station 3212.

As shown in fig. 12, the operation process of the batch screening and boxing system 100 for weld nuts in the present embodiment includes the following steps:

in step S1, the worker puts the batch of weld nuts a produced and processed into the bucket 111.

In step S2, the batch of the weld nuts a enters the conveying bucket 12 through the guide belt 112 and enters the moving table 21 through the conveying path.

In step S3, the plurality of profile information collection units collect the structural profile information of the batch of weld nuts a that rotate with the mobile station 21.

In step S4, the sorting control unit 23 sorts the weld nuts a based on the configuration profile information and controls the blower 24 to blow the weld nuts a that are non-conforming pieces into the outlet passage 25.

Step S5, the operator places the parts box (placed on the transfer box tooling 40) on the placing station 3211, the parts box stops at the transfer station 3212 through the first conveyor belt 321 and the first limit sensor 35, and then stops at the boxing station 3311 through the transfer assembly 34 and the second limit sensor, and boxes the welded nuts a that are the qualified parts (placed on the transfer box tooling 40).
