Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic bending welding technology, specifically relating to an ultrasonic high-avoidance bending welding structure. Background Technology

[0002] The existing ultrasonic bending welding is one of the existing welding equipment, and the ultrasonic high-avoidance bending welding, through the high-avoidance bending welding head structure, can meet the needs of most terminals on the market and meet the requirements of automated production.

[0003] Most existing ultrasonic bending welding structures use 180° full-wavelength and half-wavelength welding structures, and employ a cross-shaped structure as the welding structure in the adjustment mechanism. This results in relatively high manufacturing costs and a relatively large structural space occupation, which is not conducive to the overall miniaturization of the equipment. At the same time, manual adjustment of the slider and welding head position and gap position depends on the skill of the personnel and cannot guarantee the accuracy of each adjustment. It requires continuous adjustment to the appropriate position, and the adjustment position is narrow. This leads to long setup time and low adjustment efficiency in the early stage of equipment production. Therefore, this utility model proposes an ultrasonic high-avoidance bending welding structure. Utility Model Content

[0004] The purpose of this utility model is to provide an ultrasonic high-avoidance bending welding structure to solve the problems mentioned in the background art, such as the use of a cross as the welding structure in the ultrasonic bending welding adjustment structure, which has relatively high manufacturing cost and relatively large structural space occupation. At the same time, the manual adjustment of the slider and welding head position and gap position depends on the skill of the personnel and cannot guarantee the accuracy of each adjustment. It requires continuous adjustment to the appropriate position, and the adjustment position is narrow and the adjustment efficiency is low.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic high-avoidance bending welding structure, comprising an ultrasonic bending welding body, the ultrasonic bending welding body including a main frame, a support base provided at the bottom of the main frame, an ultrasonic welding head provided at the middle of the front surface of the main frame, and the ultrasonic bending welding body further comprising:

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a lifting and sliding clamping mechanism, when the ultrasonic bending welding body is in use, the pushing cylinder moves through the inclined extrusion block to push the bottom inclined slider to slide inside the slide groove.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an ultrasonic high-avoidance bending welding structure, including an ultrasonic bending welding body 100, the ultrasonic bending welding body 100 including a main frame 101, a support base 103 provided at the bottom of the inner part of the main frame 101, an ultrasonic welding head 102 provided at the middle position of the front surface of the main frame 101, and the ultrasonic bending welding body 100 is also provided with:

[0023] The lifting and sliding clamping mechanism includes a lifting adjustment component located at the connection between the ultrasonic welding head 102 and the top of the main frame 101, and a sliding clamping component located inside the support base 103. A drive component is located on one side of the sliding clamping component. When the ultrasonic bending welding body 100 is in use, it can be lifted, welded and clamped and fixed through the lifting and sliding clamping mechanism. During welding, a high clearance method is achieved through the Z-axis module 1022, which occupies little space, has low cost, and provides precise and convenient adjustment. At the same time, the bottom inclined slider 1033 drives the clamping plate 1031 to slide left and right, which facilitates the adjustment of the gap with the ultrasonic welding head 102 and provides high flexibility.

[0024] To facilitate the lifting and lowering of the ultrasonic welding head 102 for welding and achieve a high clearance method through the lifting and adjusting assembly, in this embodiment, preferably, the lifting and adjusting assembly includes a fixed mounting plate 1023 on the rear surface of the ultrasonic welding head 102.

A lifting cylinder 1021 is fixed to the top of the main frame 101 by mounting bolts. The bottom end of the lifting cylinder 1021 is fixed to the upper surface of the Z-axis module 1022 by mounting bolts. The lifting cylinder 1021 drives the Z-axis module 1022 and the ultrasonic welding head 102 to achieve lifting and lowering welding. During welding, the Z-axis module 1022 achieves a high clearance method, which occupies little space, has low cost, is precise and convenient to adjust, has a high clearance position, and is highly compatible with various irregular terminals.

[0025] In order to facilitate the clamping and fixing of the workpiece to be welded by means of the sliding clamping assembly, in this embodiment, preferably, the sliding clamping assembly includes a sliding groove 1034 formed on both sides of the upper surface of the support base 103. A bottom inclined slider 1033 slides inside the sliding groove 1034. A clamping plate 1031 is fixedly installed on the upper surface of the bottom inclined slider 1033. The bottom inclined slider 1033 can slide inside the sliding groove 1034 to drive the clamping plate 1031 to move left and right to clamp and install. The gap between the left and right sliders and the ultrasonic welding head 102 is easy to adjust and highly flexible.

[0026] In order to facilitate the sliding of the bottom inclined slider 1033 within the slide groove 1034 by means of the driving component, and to facilitate driving adjustment and clamping fixation, in this embodiment, preferably, the driving component includes two push cylinders 1032 fixed to one side of the support base 103 by mounting bolts, and the ends of the push cylinders 1032 are connected to the bottom inclined slider 1033 by a pressure block. The push cylinders 1032 can drive the bottom inclined slider 1033 to slide within the slide groove 1034 by means of the pressure block, thereby driving the clamping plate 1031 to slide and clamp and fix.

[0027] The mechanism facilitates disassembly and replacement, and includes a protective component at the end of the sliding clamping assembly. An elastic locking component is provided at the connection between the inner side of the protective component and the end side of the sliding clamping assembly. A rotation fixing component is provided at the end of the protective component. The mechanism can protect the end of the clamping plate 1031 and facilitate its replacement during welding of the ultrasonic bending welding body 100, resulting in low replacement cost.

[0028] In order to facilitate the protection of the end of the clamping plate body 1031 by means of a protective component, and to facilitate replacement when damage occurs due to long-term use, thereby reducing replacement costs, in this embodiment, preferably, the protective component includes a clamping head 104 fitted onto the end of the clamping plate body 1031. An embedded plate 1041 is integrally provided on both sides of the end of the clamping head 104. A groove 1042 is opened on both sides of the end of the clamping plate body 1031, and the embedded plate 1041 engages with the inside of the groove 1042. The clamping head 104 can be closed and protected at the end of the clamping plate body 1031 by the embedded plate 1041 engaging inside the groove 1042.

[0029] To facilitate the locking and alignment of the clamp head 104 at the end of the clamp body 1031 using the elastic locking assembly, in this embodiment, preferably, the elastic locking assembly includes limiting grooves 1048 formed on both sides of the end of the clamp body 1031. A limiting protrusion 1046 is positioned inside the limiting groove 1048. An elastic block 1047 is provided at the connection between the inner surface of the limiting protrusion 1046 and the bottom of the limiting groove 1048. Locking holes 1045 are provided on both sides of the interior of the clamp head 104. After the clamp head 104 is locked inside the clamp body 1031, the elastic block 1047 deforms to elastically lock the limiting protrusion 1046 inside the locking hole 1045, thus locking the clamp head 104 for easy alignment and installation.

[0030] To facilitate the engagement and alignment of the clamping head 104 via the rotating fixing assembly, and conversely, to facilitate disassembly and replacement, in this embodiment, preferably, the rotating fixing assembly includes a fixing bolt 1043 that is threaded inside the embedded plate 1041. The groove 1042 has an internal threaded hole 1044. The internal structure of the fixing bolt 1043 matches the internal structure of the internal threaded hole 1044. After the clamping head 104 is elastically locked at the end of the clamping plate body 1031, the rotating fixing bolt 1043 is inserted into the internal threaded hole 1044 to reinforce the clamping head 104, facilitating disassembly and assembly operations.

[0031] The working principle and usage process of this utility model: In use, the ultrasonic high-avoidance bending welding structure directly places the ultrasonic bending welding body 100 stably in the desired position by having the main frame 101 contact the ground. When the ultrasonic bending welding body 100 is in use, the workpiece to be welded is placed on the upper surface of the support base 103. Two pushing cylinders 1032 move simultaneously, respectively driving the inclined extrusion block to press against one side of the inclined surface of the bottom inclined slider 1033, causing the bottom inclined slider 1033 to slide inside the slide groove 1034. As the bottom inclined slider 1033 slides, it causes the clamping plate 1031 to slide, from... The two clamping plates 1031 clamp and fix the workpiece to be welded. At this time, the lifting cylinder 1021 moves to drive the Z-axis module 1022 to move down. The Z-axis module 1022 moves down to drive the ultrasonic welding head 102 to move down to the surface of the workpiece for welding. This facilitates the rapid lifting and welding process. The lifting and welding of the ultrasonic welding head 102 is achieved by the Z-axis module 1022, which occupies a small space, has low cost, is precise and convenient to adjust, has a high clearance position, and is highly compatible with various irregular terminals. At the same time, the bottom inclined slider 1033 drives the clamping plate 1031 to slide left and right, and the gap between it and the ultrasonic welding head 102 is easy to adjust and highly flexible.

[0032] Finally, before using the ultrasonic bending welding body 100, the clamping head 104 is fitted onto the end of the clamping body 1031, and the limiting protrusion 1046 is pressed into the inside of the limiting groove 1048. After the inserting plate 1041 is engaged in the groove 1042 and the clamping head 104 is engaged in place, the elastic block 1047 deforms and drives the limiting protrusion 1046 to elastically engage in the locking hole 1045. Then, the fixing bolt 1043 is rotated again to penetrate the inserting plate 1041 and engage in the internal threaded hole 1044 to fix the clamping head 104. This makes it easy to protect the clamping head 104 when clamped and fixed by the clamping body 1031. When the surface of the clamping head 104 is damaged by frequent clamping force, the clamping head 104 can be disassembled and replaced by reversing the operation. The disassembly and replacement are convenient, reducing the replacement cost and improving the clamping protection effect of the end of the clamping body 1031 and the convenience of disassembly and replacement when the ultrasonic bending welding body 100 is used for welding.
