The utility model discloses an ultrasonic bonding tool improves structure, including the bonding tool body, the first one of bonding tool body is the square body, and the lower half is the flat body, and two halves pass through cambered surface transition linking, and the up end middle part of bonding tool body is provided with the mounting hole of being connected with the transducer, and lies in the both sides of mounting hole on the up end and has seted up the ladder groove, makes the up end middle part protruding, and the ladder groove passes through quarter fillet face transition linking with the bellying, sets up the slot that extends to the lower half from first on the bonding tool body. Above-mentioned ultrasonic bonding tool improves the great condition of structure to bonding tool both sides and middle amplitude difference, has increased ladder groove and slot to current bonding tool to carry out fillet to the groove angle and handled, thereby effective adjustment amplitude, less amplitude is poor, makes the face of weld even, and has improved the heat-sinking capability, can carry out continuous vibration, and the welding is effectual, and work efficiency is high.
Description
Technical Field
The utility model relates to an ultrasonic welding technical field especially relates to an ultrasonic bonding tool improves structure.
Background
Ultrasonic welding is carried out by converting 50/60 Hz current into 15, 20, 30 or 40KHz electric energy through an ultrasonic generator. The converted high-frequency electrical energy is converted again into mechanical motion of the same frequency by the transducer, and then the mechanical motion is transmitted to the welding head by a set of amplitude-changing rod devices, the amplitude of which can be changed, and the welding head transmits the received vibration energy to the joint of the workpieces to be welded, and in the area, the vibration energy is converted into heat energy by a friction mode, plastics, fabrics and the like are melted, and welding is carried out.
As shown in fig. 2, a common ultrasonic welding head is used, and when the mask is produced, the welding head contacts with the non-woven fabric material and generates heat to weld the fabric layers together. However, in use, the welding surface is uneven, the amplitude of the two sides is about 25um, the amplitude difference of the middle part is about 18um, the welding effect is general, in order to ensure the forming quality, only intermittent vibration welding can be carried out, and the production efficiency is lower.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an ultrasonic bonding tool improves structure, through optimizing bonding tool structure, the adjustment amplitude reduces the amplitude poor, makes the face of weld even, improves welding quality.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides an ultrasonic bonding tool improves structure, it includes the bonding tool body, the first one of bonding tool body is the square body, the lower half is the flat body, two halves pass through the cambered surface transition and link up, the up end middle part of bonding tool body is provided with the mounting hole of being connected with the transducer, and the both sides that lie in the mounting hole on the up end have seted up the ladder groove, make up end middle part protruding, the ladder groove passes through quarter fillet face transition with the bellying and links up, set up the slot that extends to the lower half from first one on the bonding tool body.
Further, the grooves are arranged in two, are parallel and symmetrically arranged and are located in the vertical area of the upper end face protruding portion.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, ultrasonic bonding tool improved structure has increased ladder groove and slot to current bonding tool to the poor great condition of middle amplitude to the groove angle has been carried out fillet and has been handled, thereby effective adjustment amplitude, less amplitude is poor, makes the face of weld even, and has improved the heat-sinking capability, can carry out continuous vibration, and it is effectual to weld, and work efficiency is high.

Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1, the present embodiment provides an improved structure of an ultrasonic welding head, which includes a welding head body 1, an upper half portion of the welding head body 1 is a square body, a lower half portion is a flat body, the two half portions are transitionally connected through an arc surface 2, a mounting hole 3 connected with a transducer is disposed in the middle of an upper end surface of the welding head body 1, stepped grooves 4 are disposed on two sides of the mounting hole 3 on the upper end surface, so that the middle portion of the upper end surface is protruded, the stepped grooves 4 are transitionally connected with a protruding portion 5 through a quarter round corner surface 6, grooves 7 extending from the upper half portion to the lower half portion are disposed on the welding head body 1, two preferable grooves 7 are disposed here, and the two grooves 7 are disposed in parallel and symmetrical to each other and are located in a vertical region of the protruding portion 5 of the upper end surface.
Wherein the depth of the stepped groove 4 can be adjusted, thereby adjusting the amplitude and reducing the amplitude difference between the two sides and the middle part. The groove 7 can improve the heat dissipation capacity of the welding head, and can finely adjust the amplitude of the middle lug boss 5, so that the amplitudes at all positions are further balanced.
Found after reforming transform, the both sides amplitude 24um of this embodiment bonding tool, middle amplitude 23um, the amplitude difference obviously reduces, welds more evenly, and can realize continuous vibration, for the intermittent vibration work that originally is, the effect is higher, more is applicable to the non-woven fabrics processing.
In conclusion, the improved structure of the ultrasonic welding head of the embodiment is used for increasing the stepped groove and the groove on the existing welding head aiming at the condition that the amplitude difference between two sides of the welding head and the middle amplitude is large, and performing fillet treatment on the groove corner, so that the amplitude is effectively adjusted, the amplitude difference is small, the welding surface is uniform, the heat dissipation capacity is improved, continuous vibration can be performed, the welding effect is good, and the working efficiency is high.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
