[0032] Working principle: In this embodiment, the present invention also proposes a method for using a screw gasket to assemble a vibration plate, comprising the following steps:

[0033] Step 1: First, power on the device, then connect the air pump to the ventilation block, then put screws and gaskets into the outer cylinder shell, then start the vibration plate, the pulse electromagnet at the lower end of the vibration plate and the inclined spring sheet can drive the inner cylinder shell 2 to vibrate, thereby driving the gasket and screws in the inner cylinder shell 2 to spiral up on the vibration transmission belt 9, and the spring support device at the lower end of the outer cylinder shell 1 can use the elastic characteristics of the shock-absorbing spring 6 to reduce the influence of the vibration of the inner cylinder shell 2 on the outer cylinder shell 1, thereby avoiding the reduction of the service life of each device component in the support box 3 due to vibration;

[0034] Step 2: Then the outer cylinder shell 1 drives the screws and gaskets to rotate, and the screws and gaskets rotate to the feed port 12. The screws and gaskets are pushed into the inner cylinder shell 2 under the action of the second stopper. The size of the feed port 12 is determined so that the number of screws and gaskets entering the inner cylinder shell 2 is not too large, so as to avoid the vibration lifting effect of the device being weakened due to the overlap of the screws and gaskets. After entering the inner cylinder shell 2, the screws and gaskets will spiral up through the vibration transmission belt 9, and the screws and gaskets will rise to the end of the vibration transmission belt 9;

[0035] Step 3: Then the screws placed in a specific position will cooperate with the screw sorting belt 10, so that the screws placed in a specific position will move forward with the vibrating screw sorting belt 10, and the screws and gaskets that do not meet the placement conditions will fall down, and most of the gaskets and some screws will fall into the blanking tray 16 set at a specific position. Then, the parts in the blanking tray 16 will move forward under the vibration of the gasket sorting belt 11, and the air injection block 22 on the screening mechanism can spray gas to blow the screws and gaskets blocked at the entrance of the gasket sorting belt 11 into the outer cylinder shell 1;

[0036] Step 4, the screws then move forward following the screw sorting belt 10, and the gaskets move forward following the gasket sorting belt 11, and the two parts move forward to the end of the screw sorting belt 10, and the jet block and infrared sensor of the toggle mechanism can lift the blown screws, and the toggle mechanism can automatically lift the passing screws to a certain height, so that the jumped screws are automatically inserted into the gaskets during the falling back process, effectively preventing the screws from being unable to be inserted into the gaskets due to incomplete alignment or due to the obstruction of gasket burrs, thereby greatly improving the work efficiency of screw and gasket assembly, and the first stopper 19 can prevent the screws from being pushed too high to affect the assembly of the screws and gaskets;

[0037] Step five, finally, the screws and gaskets are assembled, the assembled screws follow the support rods forward, the unassembled screws and gaskets fall into the outer cylinder shell 1, and then the assembled screws slide to the blanking mechanism. Through the setting of the sliding motor, the spacing of the blanking rods can be adjusted to control the blanking of the screws, avoiding too fast blanking that causes the gasket to separate from the screw, or too slow blanking that affects the speed of screw and gasket assembly.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
