Abstract
The utility model provides a welding set of ultrasonic welder, it includes bonding tool and transducer, the bonding tool with connect through becoming the width of cloth pole between the transducer, the transducer become the width of cloth pole and the axis of bonding tool coincides each other, the outer peripheral face of width of cloth pole still is equipped with annular setting element, annular setting element adopts elastic material to make. The welding device of the ultrasonic welding machine of the utility model reduces the processing precision requirement of the connecting mechanism on the one hand through the annular positioning piece made of elastic material, thereby reducing the processing requirement and the manufacturing cost; on the other hand, when the welding machine works, the elastic material can absorb the vibration generated by high-frequency vibration at the connecting part, so that not only is noise pollution avoided, but also energy loss is reduced, and the welding quality is improved.
Description
Technical Field
The utility model relates to a frock platform, in particular to welding set of ultrasonic welder.
Background
When the ultrasonic welding machine is used for welding, the welding head is connected with the transducer through the amplitude transformer, the three move up and down along a straight line, the welding head compresses the welding material in the pressing process, and the welding material, the welding material and the anvil block at the bottom of the welding head jointly act to complete welding of the welding material. In the process, the amplitude transformer changes the high-frequency vibration amplitude transmitted by the transducer and then transmits the high-frequency vibration amplitude to the welding head. To prevent displacement of the horn during high frequency vibration, it is often necessary to position the horn. The amplitude transformer positioning devices commonly available in the market have two types: metal spring piece fixing device and metal locking ring fixing device. However, when the welder welds, the two devices have unreasonable structure and large noise pollution, and in addition, the problems of difficult adjustment of the installation position of the amplitude transformer, large power loss, unstable performance, easy damage of the spring piece and the like exist, thereby affecting the welding quality and stability and wasting energy.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that noise pollution is big among the order of overcoming prior art, becomes width of cloth pole mounted position and is difficult to the adjustment, and power loss is big, and the performance is unstable, and the spring leaf defects such as damage easily provide a welding set of ultrasonic welder.
The utility model discloses an above-mentioned technical problem is solved through following technical scheme:
the welding device of the ultrasonic welding machine is characterized by comprising a welding head and an energy converter, wherein the welding head is connected with the energy converter through an amplitude transformer, the energy converter, the amplitude transformer and the central axis of the welding head are overlapped, an annular positioning piece is further arranged on the outer peripheral surface of the amplitude transformer, and the annular positioning piece is made of elastic materials.
Preferably, the annular positioning piece is made of rubber.
Preferably, the annular positioning piece is made of nylon.
Preferably, the annular positioning member is made of plastic.
Preferably, the annular positioning piece is connected with the outer peripheral surface of the amplitude transformer in a clamping manner.
Preferably, the inner diameter of the annular positioning member is smaller than the diameter of the outer peripheral surface of the horn.
In the present invention, the above-mentioned preferred conditions can be combined at will on the basis of general knowledge in the field, so as to obtain the preferred embodiments of the present invention.
The utility model discloses an actively advance the effect and lie in: the welding device of the ultrasonic welding machine of the utility model reduces the processing precision requirement of the connecting mechanism on the one hand through the annular positioning piece made of elastic material, thereby reducing the processing requirement and the manufacturing cost; on the other hand, when the welding machine works, the elastic material can absorb the vibration generated by high-frequency vibration at the connecting part, so that not only is noise pollution avoided, but also energy loss is reduced, and the welding quality is improved.
Drawings
Fig. 1 is a schematic structural diagram of a welding device of an ultrasonic welding machine according to an embodiment of the present invention.
Detailed Description
The present invention will be more clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1, the welding device of the ultrasonic welding machine in the present embodiment includes a horn 1 and a transducer 2, the horn 1 and the transducer 2 are connected by a horn 3, and the central axes of the transducer 2, the horn 3, and the horn 1 coincide with each other. An annular positioning piece 4 made of rubber material is arranged on the outer peripheral surface of the amplitude transformer 3. The annular positioning element 4 has an inner diameter smaller than the maximum outer diameter of the horn 3 and is thus fixed to the horn 3 in a snap-fit manner. Of course in other embodiments, nylon or plastic may be used instead of the rubber material.
The welding device of the ultrasonic welding machine reduces the machining precision requirement of the connecting mechanism through the elastic material, so that the machining requirement and the manufacturing cost are reduced; on the other hand, when the welding machine works, the elastic material can absorb the vibration generated by high-frequency vibration at the connecting part, so that not only is noise pollution avoided, but also energy loss is reduced, and the welding quality is improved.
The technical solutions in the embodiments of the present invention are clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
