Referring to fig. 1 and 7, a leveling component 8 is disposed between the base 21 and the mounting plate 22, and the leveling component 8 is used for adjusting the balance of the mounting plate 22. The leveling component 8 comprises a supporting block 83, a nut seat 81 and a threaded sleeve 82, the supporting block 83 is connected to the base 21 in a threaded manner, and one end, away from the base 21, of the supporting block 83 is arc-shaped and abuts against the mounting plate 22. The nut seat 81 is fixed at a corner of the mounting plate 22 on a side away from the base 21, the threaded sleeve 82 is provided with an external thread, and the threaded sleeve 82 is screwed in the nut seat 81. Meanwhile, a through hole for the threaded sleeve 82 to pass through is formed in the mounting plate 22 at a position corresponding to the nut seat 81, the threaded sleeve 82 abuts against the base 21, and the fixing bolt 24 is arranged in the threaded sleeve 82 in a penetrating manner. And the nut seats 81, the threaded sleeves 82 and the fixing bolts 24 are provided in four groups, and the four groups correspond one-to-one to the four corners of the mounting plate 22. The contact point of the supporting block 83 and the mounting plate 22 and the central point of the connecting line of the midpoints of the two threaded sleeves 82 at the opposite corners of the mounting plate 22 are the same point.

An operator rotates one of the threaded sleeves 82, the threaded sleeve 82 can drive one of the corner portions of the mounting plate 22 to deflect upwards or downwards, and at the moment, the mounting plate 22 tilts on the supporting block 83, so that the effect of adjusting the balance degree of the mounting plate 22 is achieved, the operator can conveniently adjust the deflection angle of the product, and the operator can conveniently and quickly align the product with the ultrasonic welding head 12.

Referring to fig. 8, the coupling nut includes a fixing stud 131 and an adjusting stud 132, and a pitch of the fixing stud 131 is smaller than a pitch of the adjusting stud 132. During installation of ultrasonic horn 12, the operator attaches adjustment stud 132 to ultrasonic horn 12 and then secures fixing stud 131 to upper module 11. At this time, the adjusting stud 132 may be inclined to some extent by the inclination angle of the thread, so as to achieve the effect of adjusting the included angle between the ultrasonic welding head 12 and the upper module 11, and improve the flexibility of the ultrasonic welding head 12, so that the ultrasonic welding head 12 is aligned with the product.

The implementation principle of the ultrasonic welding device in the embodiment of the application is as follows: in the process of welding the product, the operator places the product on the limiting plate 23, so that the limiting plate 23 fixes the product. The operator then attaches the ultrasonic horn 12 to the upper module 11 by means of the attachment screw 13, and then fixes the support rod 31 to the base plate. The operator now places the upper module 11 on the two supports 32 so that the supports 32 support the upper module 11. Then, an operator can adjust the balance degree of the upper module 11 through the vertical adjusting piece 4, and adjust the position of the upper module 11 in the horizontal direction through the longitudinal adjusting piece or the transverse adjusting piece, so that the operator can align the ultrasonic welding head 12 with a product quickly and conveniently. Meanwhile, an operator can adjust the balance degree of the mounting plate 22 through the leveling component 8 to achieve the effect of adjusting the inclination angle of the product, so that the operator can further align the product with the ultrasonic welding head 12, the welding precision of the product is improved, and the product quality is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
