Abstract
Description
Technical Field
[0001] This utility model relates to automotive injection molding parts processing equipment, and more particularly to an ultrasonic puncture welding device for automotive injection molding parts. Background Technology
[0002] Ultrasonic puncture welding is a special ultrasonic welding technology that allows the welding process to directly penetrate the plastic weldment and contact another weldment, causing the plastic material to embed deeply. This welding method typically results in higher strength than ordinary ultrasonic welding.1 The following is relevant information about ultrasonic puncture welding: Ultrasonic puncture welding is widely used in the automotive industry, such as welding wheel arches, door panels, radar brackets, spoilers, and welding PP plastic parts to sound insulation cotton.1 Process Characteristics: A characteristic of ultrasonic puncture welding is that it causes some damage to one side of the welded area, leaving a scratch. However, if the other side is thick enough, the scratch is almost invisible. Therefore, it has little impact on the product's appearance, and no bulges will appear on the surface.
[0003] When ultrasonic piercing welding is performed on automotive injection molded parts, the surface of the product is damaged due to inaccurate positioning after the easily weldable unit is pressed close to the workpiece. In the current ultrasonic piercing welding process, too many welding equipment and positioning fixtures will lead to product scrap, increase production costs, waste of raw materials, and increase the cost and time of product waste disposal during the production process. Utility Model Content
[0004] The purpose of this invention is to provide an ultrasonic puncture welding device for automotive injection molded parts, which solves the problem of welding deviation caused by the inaccurate positioning of ordinary ultrasonic puncture welding devices for automotive injection molded parts.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an ultrasonic piercing welding device for automotive injection molded parts, including a main structure, a control panel located outside the main structure, and an ultrasonic piercing welding operation unit located in the main structure.

The ultrasonic piercing welding operation unit includes a workpiece fixture located on the upper part of the operation panel and an ultrasonic welding structure located in the mounting frame. The ultrasonic piercing welding operation unit also includes a linkage mounting base and a set of workpiece synchronous clamping fixtures located below the linkage mounting base and perpendicular to the workpiece fixture. A set of limiting slide blocks located on the operation panel are sleeved in the linkage mounting base.
[0006] The workpiece fixture includes a workpiece side end limiting block group, a workpiece middle limiting block group, and an edge limiting block group, all mounted on the operating table.
[0007] The ultrasonic welding structure includes a welding telescopic cylinder, a transducer, a welding head fixing adjuster, a wave-penetrating lifting cylinder, a wave-penetrating guide positioner, and an ultrasonic wave-penetrating welding head.
