AI Technical Summary
During the use of the screw tightening machine in the prior art, the screws will rotate relatively to the vacuum adsorption structure, resulting in wear and tear of the vacuum adsorption structure, which is low in practicality; at the same time, it is necessary to move a long distance to pick up parts far away from the loading position, which has low working efficiency.
An automatic screw tightening machine is designed, which uses the combination of lifting oil cylinder and vacuum pump to absorb screws through the vacuum pump and press the screws into the threaded holes of the components under the driving of the downcoming cylinder, and then uses a torque motor to perform tightening operation. At the same time, the automatic loading and picking of screws is achieved through the vibration disc and the vibration motor, reducing the distance requirement for the screw loading position.
The automated screw tightening process is realized, which avoids direct friction between the screw and the adsorption structure and extends the service life of the adsorption structure. At the same time, through the automatic feeding and picking functions, the working efficiency is improved and the distance and time of manual operation is reduced.

[0003] Screws generally refer to screws. Screws are tools that use the physical and mathematical principles of the inclined circular rotation of an object and the friction force to gradually tighten objects and machine parts. The main function of the screw is to connect two workpieces together and tighten them. Screws are used on general equipment and on almost all machines. Screws are an indispensable industrial necessity in daily life.
