Description

Technical Field

[0002] The existing humidifiers and their first accessories are mostly plastic products, and the existing processes such as feeding, gluing, and ultrasonic welding are all manual operations, which is not conducive to improving production efficiency, and cannot guarantee production quality, and it is difficult to further reduce production costs.

[0003] In addition, it is difficult to apply glue quantitatively and accurately by hand, and the product quality cannot be guaranteed. The traditional positioning of the imitation mold made by relying on the product shape, its vertical direction relies on the product's own gravity, which is easy to loosen during the operation of gluing and assembly, resulting in positioning failure; and adding a downward pressure mechanism on the upper part of the product will interfere with the operating mechanism.

[0004] Since the dimensional consistency of injection molded parts is difficult to control, the traditional mold positioning method is prone to defects such as inconsistent product seams after welding, resulting in an unsightly product appearance. Summary of the invention

[0020] The beneficial effects of an ultrasonic welding automated production line of the present invention are:

[0021] (1) The present invention replaces manual production with production line production, thereby improving production efficiency and reducing production costs;

[0022] (2) The tooling positioning mechanism adds a vertical force on the basis of the traditional imitation positioning mold to avoid defects such as shaking of the first accessory during operation; specifically, the rotary cylinder first presses the first accessory with the swing arm with the rubber bearing, and then extends the swing arm with the vacuum suction cup under the positioning mold to suck it firmly and pull it down, and then the upper swing arm is separated from the positioning mold to achieve the vertical force applied to the first accessory. Another advantage of this structure is that there is no obstruction on the upper part of the first accessory and it will not interfere with the operating mechanism;

[0023] (3) The auxiliary suction cup correction mechanism of the copy mold adopts the method of adding vacuum suction cups and clamping cylinders on the top and around the copy mold. After the vacuum suction cups firmly suck the first part, the cylinder pulls the first part in the opposite direction of the copy mold, so that the first part is firmly attached to the mold, and the first part is accurately positioned;

[0024] (4) During the production process of the production line, workers only need to load and unload workpieces and auxiliary materials, and the rest of the work is completed by the production line, which greatly reduces the labor intensity; the use of robots for automatic gluing can achieve quantitative and accurate gluing; the use of tooling positioning mechanisms and copy mold auxiliary suction cup correction mechanisms to achieve the vertical and horizontal positioning of the first accessory solves the problem of failure of traditional mold positioning and avoids the problem of inconsistent seams of the first accessory after welding and unsightly appearance of the first accessory;

[0025] (5) The ultrasonic welding mechanism adopts horizontal double-station operation. The welding positioning mold on one side of the ultrasonic welding machine discharges the material, and the welding positioning mold on the other side discharges the material, which improves the working efficiency.
