Detailed Embodiment

[0023] As Figure 1 and Figure 2 shown, a sorting fixture for an industrial robot includes a sorting mechanism 1. The sorting mechanism 1 includes a sorting seat 2. A weighing device 3 is arranged at the center of the top of the sorting seat 2. A weighing bottom support 4 with a square cross-section is connected to the weighing device 3 through a lifting assembly. Four weighing support rods 5 distributed in a square are fixedly connected to the top of the weighing bottom support 4. A conveyor channel 6 is formed between every two weighing support rods 5. Four discharge ports 7 corresponding to the conveyor channels 6 one by one are also arranged on the sorting seat 2. A four-way transmission and sorting assembly 8 is also arranged on the sorting seat 2.

[0024] In the present utility model, during the sorting process, the express deliveries can be divided into at most four grades according to different weights. The weighing support rods 5 on the weighing bottom support 4 can hold up the express deliveries to be weighed and weigh them through the weighing device 3. After obtaining the weight of the express deliveries, the four-way transmission and sorting assembly 8 can use the conveyor channel 6 between the two weighing support rods 5 to move the conveyor for transporting the express deliveries of the corresponding weight to directly above the weighing bottom support 4, and then drive the weighing bottom support 4 to descend through the lifting assembly so that the express deliveries placed on the weighing support rods 5 fall on the conveyor and are moved to the discharge port 7 through the conveyor, completing the sorting of the express deliveries.

[0025] Specifically, the four-way transfer sorting component 8 includes four horizontal transfer components 9 respectively arranged between four corresponding transfer channels 6 and discharge ports 7. The sorting base 2 is further provided with four transfer translator components 10 connected to the horizontal transfer components 9. The transfer translator components 10 can move the horizontal transfer components 9 through the transfer channels 6 to directly above the weighing base 4. After the weighing of the express delivery is completed, the horizontal transfer component 9 corresponding to the weight range of the express delivery can be moved to directly above the weighing base 4 under the action of the horizontal transfer component 9. Then, the lifting component drives the weighing base 4 to descend, so that the express delivery placed on the weighing rod 5 falls on the transfer device and is transferred to the discharge port 7 through the transfer device, realizing the sorting and delivery of the express delivery.

[0026] Specifically, the horizontal transfer component 9 includes a transfer base 11. A horizontal conveyor belt 12 is arranged on the transfer base 11. The two ends of the horizontal conveyor belt 12 are respectively connected to the transfer channel 6 and the discharge port 7.
