Dual rotary feeding system

Abstract

This disclosure provides a dual-rotor feeding system for arranging and transferring a plurality of test components to a test turntable. The dual-rotor feeding system includes: a base; an upper turntable rotatably mounted on the base to support the test components, the upper turntable having a first linear velocity; and a lower turntable rotatably mounted on the base, a portion of the lower turntable being located below the upper turntable, the side of the lower turntable away from the upper turntable being located above the periphery of the test turntable, such that the lower turntable is positioned between the upper turntable and the test turntable, the lower turntable and the upper turntable rotating in the same direction of rotation, the lower turntable having a second linear velocity, the second linear velocity being less than the first linear velocity. When the test components are transferred from the upper turntable to the lower turntable, the test components are densely arranged on the lower turntable and then transferred to the test turntable.

Claims

1. A dual-rotor feeding system for arranging and transferring a plurality of test components onto a test turntable, the dual-rotor feeding system comprising: A base; an upper turntable rotatably mounted on the base to support the components to be measured, the upper turntable having a first linear velocity; A lower turntable is rotatably mounted on the base. A portion of the lower turntable is located below the upper turntable. The side of the lower turntable away from the upper turntable is located above the periphery of the test turntable, so that the lower turntable is positioned between the upper turntable and the test turntable. The lower turntable and the upper turntable rotate in the same direction of rotation. The lower turntable has a second linear velocity, which is less than the first linear velocity. When the test components are transferred from the upper turntable to the lower turntable, the test components are densely arranged on the lower turntable and then transferred to the test turntable.

2. The dual rotary feeding system as described in claim 1, wherein, A motor is installed below the base, and the upper turntable is driven to rotate by the motor. The lower turntable is connected to the motor through a belt. The diameter of the pulley of the belt connected to the lower turntable is smaller than the diameter of the pulley of the belt connected to the motor. The ratio of the first linear velocity to the second linear velocity is between 1:0.57 and 1:0.

7.

3. The dual rotary feeding system as described in claim 1, wherein, The diameter of the lower turntable is smaller than the diameter of the upper turntable.

4. The dual rotary feeding system as described in claim 3, wherein, The upper turntable is a circular antistatic black sheet with a diameter of 300 mm, and the lower turntable is a circular antistatic black sheet with a diameter of 150 mm.

5. The dual rotary feeding system as described in claim 1, wherein, The dual-turntable feeding system further includes an electrostatic high-voltage module, which is located below the lower turntable and adjacent to the test turntable.

6. The dual rotary feeding system as described in claim 1, wherein, A cover plate is connected above the base, and a plurality of alignment guides for arranging the components under test are attached to the inner side of the cover plate.

7. The dual rotary feeding system as described in claim 6, wherein, The multiple array of guide bars consists of an inlet guide bar located above the upper turntable, multiple outer ring guide bars, an outlet guide bar, and a final guide bar located above the lower turntable. The dual turntable feeding system further includes a vacuum adsorption module and a pneumatic propulsion module.
