Specifically, the sorting driver 11 can be a cylinder.

[0031] In actual application, according to the torque detection result of the torque detection device 3 on the material, when the material is good, the sorting driver 11 drives the sorting member 10 to move, so that the good material trough 13 of the sorting member 10 is connected with the material drop trough 12, and after the clamping mechanism 4 releases the material, the material falls into the good material trough 13 through the material drop trough 12 under the action of gravity, and then falls onto the good product output mechanism 7; when the material is defective, the sorting driver 11 drives the sorting member 10 to move in the opposite direction, so that the defective material trough 14 of the sorting member 10 is connected with the material drop trough 12, and after the clamping mechanism 4 releases the material, the material falls into the defective material trough 14 through the material drop trough 12 under the action of gravity, and then falls onto the defective product output mechanism 8. This structural design can realize the accurate sorting of good materials and defective materials.

[0032] In this embodiment, the clamping mechanism 4 includes a material table 15 installed on the machine table 1, a clamping driver 16 installed on the side of the material table 15 away from the feeding mechanism 5, and two clamping members 17 installed on the two output ends of the clamping driver 16.

Specifically, the opening and closing driver 34 can be a cylinder, the material clamping driver 16 can be a finger cylinder, and the feeding mechanism 5 can be a conveyor belt module.

[0033] In actual application, the feeding mechanism 5 conveys the material into the material guide trough 18, so that the material enters the material receiving transverse groove 19 one by one along the material guide trough 18, and the inner wall of the material receiving transverse groove 19 limits the material. At this time, the opening and closing block 35 closes the through groove 20, and then the clamping driver 16 drives the two clamping members 17 to move closer to each other, so that the clamping members 17 can drive the material to move along the material receiving transverse groove 19 until the two clamping members 17 clamp the material. At this time, the material is located above the opening and closing block 35, close to the material guide trough 18. The clamping piece 17 blocks the discharge end of the material guide trough 18. After the torque detection device 3 completes the torque detection on the material clamped by the clamping mechanism 4, the opening and closing driver 34 drives the opening and closing block 35 to move outward, so that the opening and closing block 35 opens the through slot 20.

The sensing end of the sensor is exposed in the sensing hole 37, and the sensor is electrically connected to the material clamping driver 16.

[0036] In actual application, the feeding mechanism 5 conveys the material to the guide trough 18, and the material moves along the guide trough 18 to the receiving position 22 of the receiving transverse trough 19. At this time, the material is located between the two clamping members 17. After the sensor senses that there is material at the receiving position 22, it feeds back a signal to the clamping driver 16, so that the clamping driver 16 drives the two clamping members 17 to move closer to each other, so that the two clamping members 17 clamp the material at the receiving position 22 to the bottom of the drop trough 12, and the clamping member 17 close to the side of the guide trough 18 blocks the discharge end of the guide trough 18.

The torque sensor 27 is connected to the sorting driver 11 by signal. Specifically, the rotation driver 26 can be a motor, and the lifting drive mechanism 24 can be a linear drive module in the prior art.
