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.

Referring to fig. 1-8, the welding mechanism 10 provided in the embodiment of the present application has advantages of high efficiency and strong adaptability compared to the welding mechanism in the related art. Specifically, the welding mechanism 10 in the present embodiment includes a fixed bracket 200, a plurality of (two or more) welding assemblies 300, and a driving assembly 100.

The fixing bracket 200 is used to fix each welding assembly 300, and the fixing bracket 200 is connected to the driving assembly 100 and driven by the driving assembly 100. The detailed structure of the fixing bracket 200 may be determined according to specific requirements, and it is only necessary to fix each welding assembly 300 and drive each welding assembly 300 to move under the driving of the driving assembly 100.

The number of the welding assemblies 300 is plural. For convenience of description, the number of the welding assemblies 300 is exemplified as three hereinafter. It should be noted that the number of the welding assemblies 300 is three, which is only one specific embodiment, and in other embodiments, the number of the welding assemblies 300 may be two or more than three. Three welding assemblies 300 are fixed to the fixing bracket 200. Each of the three welding assemblies 300 includes a horn 370 and a transducer coupled to the horn 370, with each welding assembly 300 being distributed about an axis. When the number of the welding sets 300 is plural, the configurations of the welding sets 300 may be the same or different. And the arrangement distance and the relative arrangement position of each welding assembly 300 with respect to the aforementioned axis may be the same or different.

In one particular embodiment, the transducer may include a fastener 360, a horn 350, a piezoelectric patch 340, a pressure block 330, and a lockbolt 320. The fastener 360 is connected at each end to the horn 350 and the horn 370. The fastener 360 is provided at both ends with threads adapted to the horn 350 and the horn 370, respectively. The locking bolt 320 penetrates through the middle part of the pressing block 330 and the middle part of the piezoelectric sheet 340 and is connected with the amplitude transformer 350, so that the pressing block 330 and the piezoelectric sheet 340 are installed on the amplitude transformer 350. The piezoelectric sheet 340 is used for generating ultrasonic vibration to realize conversion from electric energy to mechanical energy, the amplitude transformer 350 is used for transmitting and amplifying the amplitude of the ultrasonic vibration, and the pressing block 330 is used for fixing the piezoelectric sheet 340 and giving initial pretightening force to the piezoelectric sheet 340 to realize stable ultrasonic output.

The driving assembly 100 is connected to the fixing bracket 200 and configured to drive the fixing bracket 200 to rotate, thereby driving each welding assembly 300 to rotate around the axis. Since each welding assembly 300 is arranged around the axis, each welding assembly 300 rotates around the axis after the driving assembly 100 drives the fixing bracket 200 to rotate.

In this embodiment, since the welding mechanism 10 is provided with a plurality of welding assemblies 300, and each welding assembly 300 has a transducer and a welding head 370, each welding assembly 300 can work independently.

On the one hand, welding mechanism 10 in this application can be used for welding a plurality of parts simultaneously, has promoted welding efficiency. On the other hand, because drive assembly 100 can drive each welding subassembly 300 and rotate around aforementioned axis, welding mechanism 10 in this application can also be used for using different welding subassemblies 300 to carry out welding operation at same station to can be at the work piece of same station processing different sizes and different welding parts, need not change the station when making operating personnel weld the work piece of different shapes size and welding parts, still have higher suitability when having promoted welding efficiency.

In yet another aspect, since each welding assembly 300 of the present application has a transducer, only one welding assembly 300 of the present application may be operated, and the other welding assemblies 300 may not be operated, so that the welding mechanism 10 of the present application may also handle a scenario in which only a single product needs to be welded.

Each welding head 370 comprises a welding wall 371, respectively, and two or more products to be welded are brought into contact with the welding wall 371 or a part arranged on the welding wall 371 after piecing together, thereby obtaining mechanical energy. Obviously, the arrangement position of the welding wall 371 determines the welding position when the work to be welded is welded. Since each welding assembly 300 rotates about the aforementioned axis, in order to facilitate welding, in one embodiment, each welding wall 371 is disposed away from the axis. When the welding part deviates from the rotating axis, the welding workpiece is more conveniently contacted with the welding wall 371, and the convenience of operation is improved.

When the number of the welding assemblies 300 is plural, the arrangement distance and the relative arrangement position of each welding assembly 300 with respect to the aforementioned axis may be the same or different. However, for ease of machining, in one specific embodiment, each of the welding assemblies 300 is arranged in a circular array about the axis, and the spacing between each two adjacent welding assemblies 300 is equal along the circumference of the axis. In other words, the center of each weld stack 300 is equidistant from the aforementioned axis, and the center of each weld stack 300 is equidistant from the centers of adjacent weld stacks 300. For example, when the number of the welding assemblies 300 is three, the connecting lines of the centers of the three welding assemblies 300 form an equilateral triangle, and the axis passes through the center of the equilateral triangle. In the above embodiment, the welding assemblies 300 are uniformly arranged, which facilitates the manufacturing of the fixing bracket 200.

Each welding assembly 300 includes two transducers, the two transducers of each welding assembly 300 being disposed at opposite ends of a welding head 370 coupled thereto. Specifically, when the welding mechanism 10 has three welding assemblies 300, for a total of three welding heads 370 and six transducers, each welding assembly 300 has one welding head 370 and two transducers, with two transducers disposed at opposite ends of each welding head 370. Two transducers are arranged on each welding assembly 300, and the two transducers are respectively arranged at the two ends of the welding head 370, so that the mechanical energy received by the welding head 370 can be increased, the problem of insufficient welding is effectively solved, and the welding reliability is improved. And is also beneficial to overcoming the steric hindrance defect during welding and welding workpieces with length, width, large size and multiple layer thickness. Meanwhile, the structure that the two transducers are respectively arranged at the two ends of the welding head 370 is more beneficial to the superposition of the energy of the two transducers, and the energy loss is reduced.

The mounting bracket 200 may be coupled to any portion of the weld stack 300. when the weld stack 300 includes two transducers, in one embodiment, the mounting bracket 200 couples each of the two transducers of each weld stack 300. In this way, the energy generated by the two transducers can be more stably transferred to the centrally located bonding tool 370, reducing the escape of energy.

Specifically, the fixing bracket 200 may include a connecting shaft 230, a first connecting plate 210, and a second connecting plate 220. The connecting shaft 230 is arranged to extend in a direction parallel to the axis, and the axis passes through the connecting shaft 230. Further, the central axis of the connecting shaft 230 may coincide with the aforementioned axis. The first connection plate 210 includes the same number of first connections 211 as the welding assemblies 300, and each of the first connections 211 connects one of the transducers of one of the welding assemblies 300. The second connection plate 220 includes the same number of second connection portions 221 as the welding packs 300, and each of the second connection portions 221 is connected to another transducer of one welding pack 300. The first connecting plate 210 and the second connecting plate 220 are respectively connected to two opposite ends of the connecting shaft 230.

Illustratively, when the number of the welding assemblies 300 is three, the first connection plate 210 has three first connection portions 211, and the second connection plate 220 has three second connection portions 221. Each of the welding assemblies 300 has one end connected to one of the first connection parts 211 and the other end connected to one of the second connection parts 221. That is, each of the welding assemblies 300 is disposed to extend from one of the first connection portions 211 toward one of the second connection portions 221. It should be noted that the length of each welding assembly 300 may be parallel to the axis or may intersect the axis. Referring to FIG. 7, in one particular embodiment, the length of each weld stack 300 is oriented parallel to the length of the aforementioned axis. In the above embodiment, the vibration directions of the welding assemblies 300 are substantially consistent, so that energy does not generate interference if the welding assemblies 300 work at the same time, and the placement positions of the welding assemblies 300 can be substantially similar if the welding assemblies 300 work at the same station, thereby facilitating the assembly of the whole welding mechanism 10.

Referring to fig. 5-6, in a further embodiment of the present application, each first connection portion 211 includes a first clamping arm 2111 and a second clamping arm 2112 disposed opposite the first clamping arm 2111, respectively. The first 2111 and second 2112 clamp the transducer together. The wall surface of the first clamping arm 2111 facing the second clamping arm 2112 is a first wall surface, the wall surface of the second clamping arm 2112 facing the first clamping arm 2111 is a second wall surface, the first wall surface and the second wall surface are connected and combined to form a first arc-shaped wall surface 2113, the central angle corresponding to the first arc-shaped wall surface 2113 is greater than one hundred eighty degrees, a plurality of first convex teeth 2114 are arranged on the first arc-shaped wall surface 2113, and the first convex teeth 2114 are arranged along the circumferential direction of the first arc-shaped wall surface 2113.

Each first connection portion 211 further includes a first threaded connection (not shown) that is threadedly connected to the first and second clamping arms 2111 and 2112, respectively, to adjust the distance between the first and second clamping arms 2111 and 2112. In this embodiment, the transducer can be fixed and separated by adjusting the distance between the first holding arm 2111 and the second holding arm 2112. After the transducer is placed between the first clamping arm 2111 and the second clamping arm 2112, the first clamping arm 2111 and the second clamping arm 2112 are controlled to move towards each other by rotating the first threaded connection, so as to clamp the transducer. Because the first convex tooth 2114 is arranged on the first arc-shaped wall surface 2113, the relative displacement between the first arc-shaped wall surface and the first connecting part 211 in the working process of the transducer can be effectively prevented, and the connection is more stable. Moreover, fastening by a threaded connection may enable the first connection portion 211 to fit transducers of different sizes, with greater adaptability.

Each of the second connection portions 221 further includes a second screw connector (not shown in the drawings), which is respectively screw-connected to the third clamping arm and the fourth clamping arm to adjust a distance between the third clamping arm and the fourth clamping arm. In this embodiment, the distance between the third holding arm and the fourth holding arm is adjusted to fix and separate the transducer. After the transducer is placed between the third clamping arm and the fourth clamping arm, the third clamping arm and the fourth clamping arm are controlled to move towards the direction close to each other by rotating the second threaded connecting piece so as to clamp the transducer. Because the second convex teeth are arranged on the second arc-shaped wall surface, the relative displacement between the second arc-shaped wall surface and the second connecting part 221 in the working process of the transducer can be effectively prevented, and the connection is more stable. Moreover, fastening by a threaded connection may enable the second connection portion 221 to be adapted to transducers of different sizes, with greater adaptability.
