According to fig. 2, an ultrasonic assembly 2 is provided on a base 1, the ultrasonic assembly 2 includes an upper die structure 21 and a lower die structure 22, a welding cavity for placing a material body is formed on the lower die structure 22, and the upper die structure 21 is used for transmitting a high-frequency signal to the material body.

Specifically, the upper die structure 21 is a welding head, and when vibration energy is transferred to the upper die structure 21, the vibration energy is converted into ultrasonic energy capable of exciting molecular vibration of the material body by the upper die structure 21, and then the ultrasonic energy is emitted toward the welding contact surface of the unfinished material body, so that friction heat is generated at the welding contact surface of the material body, and at this time, the material of the welding contact surface of the unfinished material body is melted or softened; the lower die structure 22 is used for positioning the unfinished material body, and the lower die structure 22 is arranged right below the upper die structure 21 and is used for fixing and supporting the unfinished material body; more specifically, in the welding process, pressure is applied to the material body through the lower die structure 22, so that the outer side of the material body can be tightly attached to the cavity wall of the welding cavity, and therefore the temperature and the welding quality of the welding contact surface of the material body are improved, and the occurrence of air gaps and looseness are prevented, so that the welding effect is influenced.

For example, the body is fed into the welding cavity of the lower die structure 22 to ensure that the unfinished body is located in the radio frequency direction of the upper die structure 21, and ultrasonic wave conduction is achieved by the mechanical vibration of the upper die structure 21, so as to transfer ultrasonic energy to the unfinished body, thereby increasing the local heat of the welding area of the unfinished body and achieving melting or softening.

To improve the conveying efficiency of the non-finished material; for this purpose, as shown in fig. 2, the conveyor assembly 3 comprises a first drive 31, a second drive 32 arranged on the output shaft of the first drive 31 and at least two holding means 33 for holding the material, the second drive 32 being in driving connection with each holding means 33; when each clamping structure 33 clamps the finished product material and the unfinished product material, the second driver 32 drives each clamping structure 33 to rise, and the first driver 31 drives the second driver 32 to move to the former clamping structure 33 to place the unfinished product material in the welding cavity, and the latter clamping structure 33 places the finished product material in the blanking area.

Specifically, the former clamping structure 33 and the latter clamping structure 33 are symmetrically arranged, so that the second driver 32 drives the two clamping structures 33 to move downwards until the two clamping structures 33 can clamp the finished product material body and the unfinished product material body respectively, the second driver 32 drives the two clamping structures 33 to move upwards so as to enable the unfinished product material body to rise to a certain height and separate from the welding cavity of the lower die structure 22, then the output shaft of the first driver 31 pushes the second driver 32 to move, namely, drives the two clamping structures 33 clamped on the unfinished product material body and the finished product material body respectively to move until each former clamping structure 33 conveys the unfinished product material body to the welding cavity of the lower die structure 22, and the latter clamping structure 33 conveys the finished product material body to the blanking area, after each clamping structure 33 releases the unfinished product material body and the finished product material body respectively, the output shaft of the first driver 31 pulls the second driver 32 to return so as to drive the former clamping structure 33 to move to a position capable of clamping the unfinished product material body, and simultaneously the output shaft of the second driver 31 moves, namely, the two clamping structures 33 are driven to move respectively, and the former clamping structure 33 can convey the unfinished product material body to the welding cavity and the finished product material body to the blanking area, thereby the production efficiency is improved, and the finished product material body can be conveyed to the position in the blanking area.

For example, when the upper die structure 21 finishes welding the first material in the welding cavity in the lower die structure 22, the second driver 32 drives each clamping structure 33 to move downward, the former clamping structure 33 clamps the second material, the latter clamping structure 33 clamps the first material, and after the second driver 32 drives each clamping structure 33 to move upward, the output shaft of the first driver 31 pushes the second driver 32 to move, so that the latter clamping structure 33 moves the first material into the blanking area to release, and the former clamping structure 33 moves the second material into the welding cavity in the lower die structure 22 to release; then, the output shaft of the first driver 31 pulls the second driver 32 to return, so that the former clamping structure 33 moves to a position capable of clamping the third material body, and at the same time, the latter clamping structure 33 moves to a position capable of clamping the welded second material body, and the operation is repeated, so that the conveying efficiency of the material body is improved.

It is understood that the first driver 31 and the second driver 32 in the embodiment of the present utility model are both cylinders; specifically, when the air inlet valve is opened, air enters the air cylinder through the air inlet and is used for filling the air cylinder cavity, after the air inlet valve is closed, the air in the air cylinder cavity is sealed in the air cylinder cavity, and at the moment, the air pressure in the air cylinder cavity can be increased by increasing the pressure of compressed air outside the air cylinder cavity, so that thrust is formed, and when the air pressure reaches a certain degree, the output shaft is subjected to the thrust action, and linear reciprocating movement is realized.

Specifically, when the material body is clamped, the air cylinders 331 respectively push the clamping portions 332 to move along the directions away from each other, so that the interval distance between the two clamping portions 332 is increased, so that the material bodies with different outer diameters can be clamped, and then the air cylinders 331 pull the clamping portions 332 to move along the directions close to each other until the opposite side surfaces of the two clamping portions 332 can simultaneously abut against the side walls of the material body, so that the material body can be clamped fixedly; when the material is released, the air cylinders 331 respectively push the clamping portions 332 to move along the directions away from each other until the material can fall off.

In a further embodiment, the opposite side of each clamp 332 is formed with an arcuate surface 3321 for abutment with the body. Specifically, because the radian of the arc surface 3321 is matched with the outer side wall of the material body, when the two clamping portions 332 are close to each other, the arc surface 3321 on each clamping portion 332 is simultaneously abutted against the outer side wall of the material body, so that the contact area between the clamping portion 332 and the material body is increased, sufficient friction force is provided to prevent the material body from sliding or shaking in the clamped process, and the stability of the material body clamped by the two clamping portions 332 is improved to prevent the material body from falling off easily.

In a specific embodiment, the conveying assembly 3 further comprises a mounting plate 34, each clamping structure 33 is symmetrically arranged on the mounting plate 34, and the output shaft of the second driver 32 is connected with the mounting plate 34.
