Description

Technical Field

[0001] The utility model relates to the field of ultrasonic welding, and in particular to a connection structure of an ultrasonic welding head and an ultrasonic welding device. Background Art

[0002] Traditional ultrasonic welding equipment has long been constrained by fixed-size ultrasonic welding heads. These structural limitations often hinder flexibility in adapting to the diverse specifications required by the market. This situation not only hinders overall productivity improvements but also limits the pace of innovation within the manufacturing industry. Of particular concern is the widespread lack of left-right or fore-aft adjustment of the ultrasonic welding head, essentially locking all options into a single left-right installation mode. This rigid setup presents numerous operational challenges.

[0003] In actual production environments, this rigidly oriented installation creates unnecessary obstacles to the loading process, especially when handling complex or large workpieces to be welded. This often creates a dilemma for workers. Limited by the welding head's angle, the assembly process, which should be simple and quick, becomes extremely cumbersome, sometimes even requiring additional manual intervention to complete positioning, significantly slowing down the production line and increasing production costs.

[0004] In view of this, the current market urgently calls for a new solution that can break the convention and break through the limitations of the existing framework, a multifunctional ultrasonic welding device that is compatible with welding heads of various specifications and can achieve free direction change. Utility Model Content

[0005] In view of this, the utility model provides a connection structure of an ultrasonic welding head and an ultrasonic welding device, which can realize the left-right or front-back installation of the ultrasonic welding head and can be compatible with connecting ultrasonic welding heads of different specifications.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A connection structure for an ultrasonic welding head comprises a base, a power unit and a welding head connection mechanism; the power unit is arranged on the base; the welding head connection mechanism is used to realize the left-right or front-back installation of the ultrasonic welding head, and comprises a mounting base connected to the power unit, a movable part connected to the mounting base and used to connect and fix the ultrasonic welding head, and the movable part can be adjusted in direction relative to the mounting base; the movable part comprises a welding head mounting part with an adjustable position for connecting and driving the ultrasonic welding head to move.

[0008] The connection structure of the ultrasonic welding head can realize the left-right or front-back installation of the ultrasonic welding head, and is compatible with connecting ultrasonic welding heads of different specifications.

[0009] Specifically, the welding head connection mechanism in this design utilizes a clever combination of a mounting base and a movable member, the movable member being adjustable relative to the mounting base. This means that when working with different orientations of the welding target, the welding head can be easily adjusted left-right or forward-backward, significantly increasing the operational flexibility of the equipment. This design allows operators to quickly adjust the welding head position according to specific work requirements, improving work efficiency while also reducing the additional time and cost associated with frequent fixture changes.

[0010] The adjustable horn mounting allows this ultrasonic horn connection structure to support a wide range of horn specifications, ensuring secure connections for horns of varying sizes and shapes. This eliminates the need to purchase dedicated connection devices for each horn model, significantly reducing equipment investment costs and simplifying inventory management. Whether facing complex and changing product lines or unexpected special orders, this connection structure can respond quickly, ensuring continuous production line operation and high-quality output.

[0011] Preferably, the movable part is detachably connected to the mounting base.

[0012] The movable parts and the mounting base adopt a "detachable" connection mechanism, that is, the movable mounting plate can be conveniently locked or unlocked with the mounting base through threaded parts. The detachable connection facilitates maintenance work. When a part is worn or fails, only the damaged component needs to be replaced in a targeted manner, without the need to scrap the entire device. This undoubtedly further saves the company's operating costs.

[0013] Preferably, the movable part includes a movable mounting plate detachably connected to the mounting base, the upper surface of the movable mounting plate is provided with a cross-shaped groove, the lower surface of the mounting base is provided with a straight-shaped protrusion that cooperates with the cross-shaped groove, and the movable mounting plate and the mounting base are locked by a screw.

[0014] The structural features of the cross-shaped groove and the straight-shaped protrusion are utilized between the movable mounting plate and the mounting base to form a combination that is both stable and flexible. This allows the movable mounting plate to be adjusted 90° relative to the mounting base, and the straight-shaped protrusion on the lower surface of the mounting base is embedded in the cross-shaped groove of the movable mounting plate. The two are tightly combined to form a stable support platform. Even in a high-speed vibration welding environment, the welding head can maintain stable operation and prevent unnecessary displacement or deflection, thereby ensuring a high level of welding quality.

[0015] Preferably, the movable mounting plate is provided with an oblong hole, and the welding head mounting portion is connected to the oblong hole.

[0016] The movable mounting plate is equipped with an oblong hole. This hole allows for adjustment of the welding head along its extended length, increasing spatial flexibility and ensuring that the welding head operating area and the power unit are always coaxially aligned. The power unit can more smoothly and efficiently deliver kinetic energy to the welding head accurately, significantly improving the welding head's performance and welding quality, achieving a perfect synergy between power and function, and ensuring excellent welding results. This carefully conceived design not only optimizes the overall structural layout, but also demonstrates the exquisite craftsmanship and ingenuity of the details.

[0017] Preferably, a mounting groove is provided at the lower portion of the mounting base, a mounting block is embedded in the mounting groove, and the I-shaped protrusion is provided on the mounting block.

[0018] There is a mounting groove at the bottom of the mounting base, and the mounting block embedded inside becomes the connection core. The I-shaped protrusion is set on it, which not only strengthens the stability between the components, but also ensures the convenience of assembly and disassembly of the device.

[0019] Preferably, the base body is provided with an avoidance area, and the avoidance area provides avoidance space when the ultrasonic welding head is installed in the front-to-back direction.

[0020] The avoidance area inside the base provides the necessary avoidance space for the front-to-back installation of the ultrasonic welding head without taking up additional space, effectively avoiding the problem of being unable to install the ultrasonic welding head in the front-to-back direction due to space limitations, and greatly enhancing the operating convenience and on-site adaptability of the equipment.

[0021] Preferably, the horn mounting portion includes a ferrule for sleeve-mounting the ultrasonic horn or a clamping claw for clamping the ultrasonic horn.

[0022] The welding head mounting part adopts a ring or clamping design, which can be used to fit the ultrasonic welding head through the ring to achieve a close fit and stable fixation; a clamping method can also be selected to facilitate quick loading and unloading and to meet different size requirements. This flexible and adjustable solution not only meets the personalized customization requirements in industrial production, but also demonstrates the careful consideration behind technological innovation, bringing unprecedented convenient experience to users, and truly starting from the details to comprehensively improve product quality and competitiveness.

[0023] Preferably, the movable part has one or two welding head mounting parts.

[0024] The movable part can be equipped with one or two welding head mounting parts to adapt to the connection and installation of ultrasonic welding heads of different specifications.

[0025] Preferably, the movable part has a horn mounting portion, and an abutment portion cooperating with the horn mounting portion and used to keep the ultrasonic horn in a horizontal state, and the abutment portion abuts against the upper portion of the ultrasonic horn from top to bottom.

[0026] The horn mounting portion of the movable part works in conjunction with an abutment to form a stable support system. This abutment precisely applies force to the upper portion of the ultrasonic horn from top to bottom, ensuring the horn maintains an ideal horizontal position during operation. This high level of parallelism reduces the likelihood of weld defects and improves yield. The stable working posture also helps extend the horn's service life and reduces the cost of frequent maintenance.

[0027] Preferably, a welding head angle adjuster is also included to adjust the angle of the ultrasonic welding head.

[0028] An ultrasonic welding device includes the ultrasonic welding head connection structure as described above and also includes an ultrasonic welding head.

[0029] The ultrasonic welding device made by the above-mentioned ultrasonic welding head connection structure can realize the left-right or front-back installation of the ultrasonic welding head, and is compatible with connecting ultrasonic welding heads of different specifications.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The connection structure of the ultrasonic welding head of the utility model can realize the left-right or front-back installation of the ultrasonic welding head, and is compatible with connecting ultrasonic welding heads of different specifications.
