Description

Technical Field

[0001] This utility model relates to the field of interior trim panel processing technology, specifically to an ultrasonic welding device for processing the lower trim panel of the rear door. Background Technology

[0002] After the lower tailgate panel is injection molded, some parts need to be welded to its surface. Connecting posts are set on the lower tailgate panel relative to the positions of the fixed parts, and connecting holes are opened on the parts relative to the positions of the connecting posts. The connecting posts are deformed by using ultrasonic welding tips to fix the parts to the lower tailgate panel. However, in actual processing, an ultrasonic welding machine is often matched with a set of welding fixtures. We need to wait for the welding to be completed and removed before we can prepare the fixtures, which greatly affects the welding efficiency. Therefore, it is particularly important to design an ultrasonic welding equipment for the processing of the lower tailgate panel to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs an ultrasonic welding device for processing the lower panel of the rear door. It is equipped with two sets of placement fixtures, which can be switched in position through the cooperation of a translation mechanism and a lifting and translation mechanism. While welding is being performed on one set of placement fixtures, preparation work can be carried out on the other set of placement fixtures. In this way, welding can be performed continuously, which greatly improves the processing efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides an ultrasonic welding device for processing the lower rear door panel, characterized in that: it includes a U-shaped upper support, a lower support plate, a placement fixture, a robotic arm, and an ultrasonic welding head fixed to the end of the robotic arm. The robotic arm is located on the left side of the upper support, and a support leg is vertically arranged at the bottom of each of the four corners of the upper support. The lower support plate is fixed between the four support legs and located directly below the upper support. There are two placement fixtures, namely a first placement fixture and a second placement fixture. The top of both the first and second placement fixtures is provided with a placement groove for placing the lower rear door panel. The top of the placement fixtures around the placement grooves is also connected to a clamping component. The first placement fixture is connected to the upper support through a translation mechanism, and the second placement fixture is connected to the lower support plate through a lifting and translation mechanism.

[0005] Furthermore, the translation mechanism includes a first slide rail, a slider, and a first translation drive electric cylinder fixed to the top of the front and rear ends of the upper support. The first slide rail is placed left and right. Two sliders are fixed to the front and rear ends of the first placement fixture. The first placement fixture is connected to the first slide rail through the sliders on the front and rear sides. The first translation drive electric cylinder is fixed to the top of the left end of the upper support. The output shaft end of the first translation drive electric cylinder is connected to the first placement fixture.

[0006] Furthermore, the lifting and translating mechanism includes a second slide rail, a slide plate, a second translation drive cylinder, and a telescopic cylinder, all located on the top of the lower support plate. The second slide rail is also positioned horizontally. The slide plate is connected to the second slide rail via a groove at the bottom. The second placement fixture is connected to the slide plate via the telescopic cylinder. The second translation drive cylinder is fixed to the top of the right end of the lower support plate, and the output shaft of the second translation drive cylinder is connected to the slide plate.

[0007] Furthermore, the clamping assembly includes a mounting cylinder, a rotating shaft, a mounting plate, a knob, a screw, and an elastic clamping end. Four or more mounting cylinders are fixed to the top of the placement fixture around the placement groove. One end of the mounting plate is connected to the mounting cylinder via a rotating shaft. The lower end of the rotating shaft extends into the mounting cylinder and is rotatably connected to it. The other end of the mounting plate has a threaded through hole that matches the screw. The knob is fixed to the upper end of the screw, and the elastic clamping end is installed at the lower end of the screw.

[0008] With the above structure, this utility model has two sets of placement fixtures. The two sets of placement fixtures can be changed in position through the cooperation of translation mechanism and lifting translation mechanism. While welding is being carried out on one set of placement fixtures, preparation work can be carried out on the other set of placement fixtures. Welding can be carried out continuously in this way, which greatly improves processing efficiency. In addition, this design also has the advantages of simple structure, convenient use and high efficiency. Attached Figure Description
