Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The ultrasonic welding machine is a special welding device applying ultrasonic technology, wherein an energy converter in the ultrasonic welding machine can convert electric energy into mechanical energy, high-frequency vibration of the order of tens of thousands of times per second is generated, and the vibration is transmitted to a welding area, so that the welding area generates local high temperature and is melted, and therefore, the workpiece is welded.

In the related art, an ultrasonic welding machine includes a horn for welding. When two workpieces to be welded are welded, the two workpieces are spliced and then contacted with a welding head, and then welding can be finished. However, the welding head of the related art is fixed in shape and position, so that it can weld only a selected workpiece, and when the shape and welding position of the workpiece to be welded are changed, the welding head of the welding machine needs to be modified to complete the welding work. Obviously, the welder in the related art is poorly adapted.

In view of this, referring to fig. 1-5, the present application provides a welding mechanism that includes a drive assembly 100, a conductive slip ring 200, and a welding assembly 300.

Conductive slip ring 200 includes a slip ring stator 210 and a slip ring rotor 220, slip ring rotor 220 being rotatable relative to slip ring stator 210. The slip ring stator 210 is provided with a first connection terminal 211, the slip ring rotor 220 is provided with a second connection terminal 221, and the first connection terminal 211 is electrically connected with the second connection terminal 221. When the slip ring rotor 220 and the slip ring stator 210 rotate with each other, the first connection terminals 211 and the second connection terminals 221 can be electrically connected to each other well regardless of the rotation angle of the slip ring rotor 220. After the external power device is electrically connected to the first connection terminal 211, the electrical signal is transmitted to the second connection terminal 221 through the first connection terminal 211.

In a specific embodiment, the slip ring stator 210 may be provided with a conductive ring, and the conductive ring is connected to the first connection terminal 211. The slip ring rotor 220 may be provided with a conductive brush, the conductive brush is in contact with the conductive ring, and the conductive brush is connected to the second connection terminal 221. When the slip ring rotor 220 rotates relative to the slip ring stator 210, the conductive brushes move in the circumferential direction of the conductive rings and constantly maintain a state of contact with the conductive rings.

The driving mechanism is connected to the slip ring rotor 220 for driving the slip ring rotor 220 to rotate relative to the slip ring stator 210. The driving mechanism includes a driving motor 110, and in one embodiment, the driving motor 110 may be directly connected to the slip ring rotor 220 to drive the slip ring rotor 220 to rotate, for example, the driving shaft 111 of the driving motor 110 is directly connected to the slip ring rotor 220. In another embodiment, the driving motor 110 may be indirectly connected to the slip ring rotor 220, for example, the driving mechanism further includes a transmission assembly 120, one end of the transmission assembly 120 is connected to the slip ring rotor 220, and the other end is connected to the driving motor 110, so as to transmit the driving force of the driving motor 110 to the slip ring rotor 220.

The welding assembly 300 is coupled to the slip ring rotor 220 and is rotatable in accordance with the rotation of the slip ring rotor 220. The welding assembly 300 includes a transducer 310 for converting electrical energy to mechanical energy and transferring the mechanical energy to a welding head 320, and a welding head 320 for contacting a workpiece to be welded for welding. The transducer 310 includes a third connection terminal 317, and the third connection terminal 317 is electrically connected to the second connection terminal 221 so that an electrical signal of an external power device can be transmitted to the transducer 310. The number of transducers 310 may be one or more. Regardless of the number of transducers 310, each transducer 310 may be electrically connected to an external power source through conductive slip ring 200.

In the above embodiment, the conductive slip ring 200 and the driving assembly 100 are added, and the conductive slip ring 200 includes the slip ring stator 210 and the slip ring rotor 220. By electrically connecting the third connection terminal 317 of the transducer 310 with the second connection terminal 221 on the slip ring rotor 220, the transducer 310 can be rotated relative to a table on which a workpiece to be welded is placed. When the driving assembly 100 drives the slip ring rotor 220 to rotate, the welding assembly 300 connected with the slip ring rotor 220 rotates, the transducer 310 of the welding assembly 300 also rotates, and because the transducer 310 and the slip ring rotor 220 rotate synchronously, wires connected with the third connecting terminal 317 and the second connecting terminal 221 do not form winding, so that the welding mechanism in the application can change the position of the workpiece to be welded relatively according to the requirement, and can adapt to the workpieces to be welded with different shapes, different positions of the welding area and different positions of the workpiece to be welded.

In particular, when the welding assembly 300 is driven by the driving assembly 100 driving the conductive slip ring 200, the rotation process of the transducer 310 and the brick changing rotor can be synchronized more, and the winding of the wires is further prevented, compared to the structure in which the driving assembly 100 directly drives the welding assembly 300.

The relative structural arrangement of the slip ring stator 210 and the slip ring rotor 220 may depend on the actual requirements. In one embodiment, the slip ring stator 210 may be sleeved outside the slip ring rotor 220; in another embodiment, the slip ring rotor 220 may also be sleeved outside the slip ring stator 210. In this embodiment, referring to fig. 3, the slip ring stator 210 includes an annular wall, the slip ring rotor 220 includes a rotating shaft 222, the slip ring stator 210 is sleeved outside the slip ring rotor 220, and the rotating shaft 222 of the slip ring rotor 220 is located at a central axis of the annular wall of the slip ring stator 210.

Both the driving assembly 100 and the welding assembly 300 are connected to the slip ring rotor 220, and particularly, the driving assembly 100 and the welding assembly 300 may be connected to the same side of the slip ring rotor 220 or to opposite sides of the slip ring rotor 220 in the direction of the rotation axis of the slip ring rotor 220. In this embodiment, referring to fig. 1-3, drive assembly 100 is coupled to one end of slip ring rotor 220 and weld assembly 300 is coupled to the opposite end of slip ring rotor 220 in a direction parallel to the axis of rotation of slip ring rotor 220. The scheme that the driving assembly 100 and the welding assembly 300 are respectively connected with the two opposite ends of the slip ring rotor 220 enables the layout space of the driving assembly 100 to be larger, the driving assembly 100 is not easy to generate position interference with the welding assembly 300, and the assembly process of the welding mechanism is also more convenient.

The welding assembly 300 further includes a welding head 320 connected to the transducer 310, the transducer 310 converts electrical energy into mechanical energy, and then transfers the mechanical energy to the welding head 320, and the welding head 320 transfers the mechanical energy to a workpiece to be welded, and the mechanical energy is converted into thermal energy on the workpiece to be welded, thereby achieving welding of the workpiece. The welding head 320 includes a welding wall 321, and the workpiece to be welded is in contact with the welding wall 321 of the welding head 320 when welding. When the slip ring rotor 220 rotates, the welding wall 321 of the welding head 320 rotates along with the slip ring rotor 220. That is, the arrangement position of the welding wall 321 is changed following the rotation of the slip ring rotor 220. In particular, when the relative positions of the welding wall 321 and the rotation axis of the slip ring rotor 220 are different, the welding wall 321 follows in a different manner. In the present embodiment, the welding wall 321 is disposed perpendicular to the rotation axis of the slip ring rotor 220, and when the welding wall 321 is perpendicular to the rotation axis of the slip ring rotor 220, the welding wall 321 moves only in a plane perpendicular to the rotation axis of the slip ring rotor 220 after the slip ring rotor 220 rotates, and the position of the welding wall 321 does not change in a direction parallel to the slip ring rotor 220. This makes the distance between the welding wall 321 and the work table on which the workpiece to be welded is placed fixed when the welding wall 321 rotates, which facilitates the welding operation.

The relative position arrangement of the driving assembly 100 and the conductive slip ring 200 may depend on actual requirements, and only needs to satisfy that the driving assembly 100 can drive the slip ring rotor 220 to rotate relative to the slip ring stator 210. In one embodiment, drive assembly 100 and conductive slip ring 200 are coupled together in the same assembly, and referring to FIG. 3, the welding mechanism further includes a mounting plate 400, and slip ring stator 210 and drive assembly 100 are coupled to mounting plate 400. The driving assembly 100 and the slip ring stator 210 are fixed on the same plate, so that on one hand, the assembly of the welding mechanism is facilitated, and on the other hand, the overall occupied space of the welding mechanism is reduced.

Referring to fig. 3-4, in one embodiment of the present application, a mounting plate 400 includes a first mounting hole 410 and a second mounting hole 420.

Drive motor 110 and conductive slip ring 200 are all arranged in the same side of mounting plate 400, and drive assembly 120 is arranged in the side of mounting plate 400 that deviates from drive motor 110. The driving motor 110 includes a driving shaft 111, the driving shaft 111 passes through the first mounting hole 410 and is coupled to the driving assembly 120, and the slip ring rotor 220 includes a rotating shaft 222, and the rotating shaft 222 passes through the second mounting hole 420 and is coupled to the driving assembly 120. Arrange driving motor 110 and conductive slip ring 200 in the homonymy of mounting panel 400 to set up transmission assembly 120 alone in the opposite side that deviates from driving motor 110, can make things convenient for transmission assembly 120's installation to arrange on the one hand like this, on the other hand, when transmission assembly 120 broke down, also conveniently dismantle and maintain transmission assembly 120.

The belt 122 is sleeved on the driving wheel 121 and the driven wheel 123 to transmit the driving force on the driving wheel 121 to the driven wheel 123. The strap 122 may be sleeved in various ways, which may be a circular ring as shown in the figure, and in other embodiments, the strap 122 may also be a splayed sleeve. In the present application, the belt 122 is used to drive the driven wheel 123, and the belt 122 is a flexible component, so that the transmission of the vibration on the transducer 310 to the driving assembly 100 can be reduced, and the driving assembly 100 is effectively protected.

That is, both transducers 310 are in communication with an external power source through conductive slip ring 200. The two transducers 310 are used for generating high-frequency vibration, so that the mechanical energy of the welding head 320 can be improved, and the problem of insufficient welding of a welding mechanism is effectively solved.

Specifically, as shown, transducer 310 includes a fastener 315, a horn 314, a piezoelectric patch 313, a compression block 312, and a locking bolt 311.
