The screws can be transported through the second guide plate, the edge limiting plate and the first guide plate, and the height of the first guide plate on one side of the storage box is higher than the height on the other side. The gap between the two first guide plates can be adjusted by two sets of fourth electric telescopic cylinders, so that various types of screws can be transported.

After the detection, the information is transmitted to the controller module. When it is detected that it is a foreign object, there is no need to compare, and the data is directly transmitted to the controller module through the data comparison module. Through the settings of the controller module and the actuator, the screws or foreign objects are distinguished and processed;

[0021] S3. The actuator can complete the transportation and assembly processing of screws, or the transportation and collection of foreign matter;

[0022] S4. The sixth motor can drive the first bidirectional lead screw to rotate, and the rotation of the first bidirectional lead screw can drive the two fourth sliders and the first clamping plate to clamp and limit the parts. The fourth motor can drive the first threaded rod to rotate, and the rotation of the first threaded rod can drive the second slider to move in the second slide groove, and the movement of the second slider can drive the first movable plate to move forward and backward.

[0023] Preferably, the step S3 also includes the following steps:

[0024] S31, the first motor drives the rotating rod and the fixed circular plate to rotate, the rotation of the fixed circular plate can drive the four connecting plates and the mounting plate to rotate, and the controller module controls the first electric telescopic cylinder to drive the first slider to move in the first slide groove, which can drive the L-shaped placement plate to move up and down;

[0025] S32, the third electric telescopic cylinder drives the sealing block to seal the top of the inner wall of the adsorption tube, and then generates suction through the suction pump to adsorb the screw. During the adsorption, the status display light on the top of the second electric telescopic cylinder will display different colors of lights for the adsorbed screws according to the data detected by the data comparison module.

[0030] 1.

The photographed picture will be transmitted to the acquisition module, and then transmitted to the detection module through the acquisition module for detection, so as to detect whether there is a screw or a foreign object in the photographed picture. When it is detected that it is a screw, it is necessary to input the data into the data comparison module for comparison with the data information in the screw model data module to determine the model of the screw and whether it is a good product. After the detection, the information is transmitted to the controller module. When it is detected that it is a foreign object, there is no need to compare.

[0031] 2. The present invention drives the rotating rod and the fixed circular plate to rotate by the first motor. The rotation of the fixed circular plate can drive the four connecting plates and the mounting plate to rotate. The controller module controls the first electric telescopic cylinder to drive the first sliding block to move in the first sliding groove, which can drive the L-shaped placing plate to move up and down, and then drive the bottom of the adsorption tube to contact the top of the screw. The third electric telescopic cylinder drives the sealing block to seal the top of the inner wall of the adsorption tube, and then generates suction through the suction pump to adsorb the screw. At the same time, the status display light on the top of the second electric telescopic cylinder will display different colors of lights for the adsorbed screws according to the data detected by the data comparison module. When the green light is on, the adsorbed screws are qualified screws of the model, and the other unqualified screws are all red lights. Therefore, the qualified screws adsorbed under the green light will be combined with the parts for processing, and the objects adsorbed under the red light will not stop and continue to rotate when they move above the parts, thereby improving the processing efficiency;

[0032] 3. The present invention drives the rotating disk to rotate by the third motor, and the rotation of the rotating disk can drive multiple digging buckets to rotate, so that the screws can be transported to the second guide plate.
