The inner groove 3 opened inside the verification table 1 is used to accommodate the first electric push rod 4, and the first electric push rod 4 can control the lifting and lowering of the rotating tray 5 to steer the upper voltage transformer body 23, so that the voltage transformer body 23 can be directly put into the equipment without distinguishing between positive and negative poles. After the steering is completed or no steering adjustment is required, the rotating tray 5 will be retracted into the inner groove 3, and the voltage transformer body 23 will be sent out by the push of the first push plate 11.

[0033] Furthermore, a through hole 7 is provided in the center of the limit plate 6 corresponding to the position of the rotating tray 5. The rotating tray 5 is movably installed inside the through hole 7. The roller 8 is installed horizontally inside the limit plate 6.

A second push plate 31 is provided at the front end of the screw rod 30. When defective products appear, the right-angle motor 29 works to control the rotation of the screw rod 30, thereby pushing out the second push plate 31, so that the second push plate 31 can push the voltage transformer body 23 located on the upper part of the parking conveyor belt 25 to the upper part of the defective product conveyor belt 27 for delivery.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
