As shown in fig. 1-2, the present embodiment provides an ultrasonic hole plugging device, which includes a bracket 1, a first ultrasonic vibration plate 2 and an ultrasonic vibration rod 3, wherein the first ultrasonic vibration plate 2 is disposed on the bracket 1 and is used for bearing a hole plugging plate 100, the first ultrasonic vibration plate 2 is provided with a through hole 21, and the through hole 21 is opposite to a hole to be plugged 101 of the hole plugging plate 100; the ultrasonic vibration rod 3 is arranged on the bracket 1, can penetrate through the through hole 21 and the hole to be plugged 101, and can directionally rotate into and out of the hole to be plugged 101.

In this embodiment, by setting the first ultrasonic vibration plate 2 and the ultrasonic vibration rod 3, the plug hole plate 100 is vibrated respectively, especially the ultrasonic vibration rod 3 can penetrate into the to-be-plugged hole 101 of the plug hole plate 100, and the ink 102 in the to-be-plugged hole 101 is vibrated sufficiently to eliminate the air bubbles 103 in the ink 102, thereby greatly reducing the occurrence of the hole void, improving the quality of the plug hole plate 100, and meeting the production requirement of the plug hole plate 100 in high-end products.

Regarding the structure of the ultrasonic vibration rod 3, in the present embodiment, the vibration head of the ultrasonic vibration rod 3 is at least partially spiral-shaped, and the length of the vibration head at the spiral-shaped position is greater than the sum of the thickness of the orifice plate 100 and the thickness of the first ultrasonic vibration plate 2, in other words, the length of the spiral section on the vibration head is greater than the sum of the thickness of the orifice plate 100 and the thickness of the first ultrasonic vibration plate 2. This arrangement ensures that the vibrating head of the ultrasonic vibration rod 3 can completely pass through the to-be-plugged hole 101 to sufficiently vibrate the to-be-plugged hole 101. Wherein, the spiral vibration head is convenient for transmitting ultrasonic vibration and rotary drainage.

When the ultrasonic vibration rod works, ultrasonic waves can be uniformly generated at 360 degrees around the ultrasonic vibration rod 3, and the ratio of the diameter of the spiral section on the vibration head of the ultrasonic vibration rod 3 to the diameter of the hole to be plugged 101 is 1/4-1/2 in order to ensure the safety of vibration.

The amplitude of the vibration of the ultrasonic vibration rod 3 can be controlled by the power level at the time of operation. Since the bubbles 103 are easy to be generated in the middle or bottom of the hole to be plugged 101 during plugging, the vibration head is lifted by the vibration head, and the vibration head is positioned at the lower part of the hole to be plugged 101 and is positioned between 1/3 and 1/2 of the depth of the vibration head, so that the vibration head can fully vibrate the ink 102 at the bottom of the hole to be plugged 101.

To achieve the rotation of the ultrasonic vibration bar 3, the elevation plate 12 is provided with a rotation member 13, and the rotation member 13 can be rotated left and right about the Z direction with respect to the elevation plate 12, in other words, the output end of the rotation member 13 can be rotated clockwise or counterclockwise. The ultrasonic vibration rod 3 is provided to the rotary member 13, and specifically, the ultrasonic vibration rod 3 is fixed to an output end of the rotary member 13. The rotating member 13 can be relatively fixed and drive the ultrasonic vibration rod 3 to directionally rotate.

Specifically, the rotary member 13 may be an electronic device such as a stepping motor or a rotary cylinder, and the ultrasonic vibration rod 3 is fixed to an output shaft of the stepping motor.

In the present embodiment, the second ultrasonic vibration plate 4, the first ultrasonic vibration plate 2, and the ultrasonic vibration rod 3 each independently operate. The arrangement of independent work can make each vibration component mutually independent, and one of them damages the back and singly changes can, reduces maintenance cost.

Then, after the rotational vibration is maintained for at least 3 seconds, the ultrasonic vibration rod 3 is rotated down to the origin; at this time, the ink 102 in the orifice may be slightly recessed, and no ink 102 overflows from the corresponding hole in the first ultrasonic vibration plate.
