Description

Technical Field

[0001] This utility model relates to the field of home appliance panel welding technology, and specifically discloses an ultrasonic welding fixture for home appliance panels. Background Technology

[0002] Ultrasonic welding machines generate a 20kHz (or 15kHz) high-voltage, high-frequency signal from a generator. This signal is converted into high-frequency mechanical vibration by a transducer system and applied to the plastic workpiece. The temperature at the interface rises due to friction between the workpiece surface and molecules. When the temperature reaches the melting point of the workpiece, the interface melts rapidly and fills the gaps between the interfaces. When the vibration stops, the workpiece cools and solidifies under a certain pressure, thus achieving a perfect weld.

[0003] Existing ultrasonic welding fixtures for home appliance panels use two relatively moving clamping plates to hold and limit the appliance panel before welding with an ultrasonic welding machine. After welding, the two clamping plates move in opposite directions to release the appliance panel, which is then manually removed and unloaded. However, the surface of the workpiece after welding retains a high temperature, and improper operation can easily burn the worker's hands, causing a safety accident. Utility Model Content

[0004] This utility model proposes an ultrasonic welding fixture for home appliance panels, which can automatically unload freshly welded home appliance panels without manual intervention, thus avoiding burns to workers' hands and potential safety accidents.

[0005] This utility model is implemented as follows: an ultrasonic welding fixture for home appliance panels includes a base, and a welding fixture mechanism is provided on the upper surface of the base.

[0006] The welding fixture mechanism includes a worktable fixedly connected to the left side of the upper end face of the base. Two vertical plates distributed front to back are fixedly connected to the middle part of the upper end face of the base. An installation strip is rotatably connected between the two vertical plates. Two clamping plates distributed front to back are slidably connected to the left side wall of the installation strip. The left ends of the two clamping plates extend to the top of the worktable. A notch is opened through the upper end face of the base on the right side. A feeding groove communicating with the notch is fixedly connected to the lower end face of the base.

[0007] As a preferred embodiment of the ultrasonic welding fixture for home appliance panels according to this utility model, a worm gear is fixedly connected to the outer wall of the mounting strip, and two mounting plates distributed on the left and right and located between two vertical plates are fixedly connected to the upper end face of the base. A worm gear that meshes with the worm gear is rotatably connected between the two mounting plates.

[0008] As a preferred embodiment of the ultrasonic welding fixture for home appliance panels according to this utility model, the left side wall of the mounting strip is provided with a sliding groove, and a bidirectional screw is rotatably connected inside the sliding groove. The right ends of the two clamping plates are fixedly connected with sliders that are threadedly connected to the bidirectional screw.

[0009] As a preferred embodiment of the ultrasonic welding fixture for home appliance panels according to this utility model, a first drive motor is installed on the right side wall of the mounting plate on the right side, and the output end of the first drive motor is fixedly connected to the worm gear.

[0010] As a preferred embodiment of the ultrasonic welding fixture for home appliance panels according to this utility model, a second drive motor is installed inside the mounting strip, and the output end of the second drive motor is fixedly connected to a bidirectional screw.

[0011] As a preferred embodiment of the ultrasonic welding fixture for home appliance panels according to this utility model, protective pads are fixedly connected to the left ends of the opposite side walls of the two clamping plates.

[0012] The beneficial effects of this utility model are:

[0013] Two clamping plates moving in opposite directions can clamp and fix the appliance panel and weld it. After welding, the mounting strip, together with the two clamping plates, drives the appliance panel to flip over to the top of the notch. Then, the two clamping plates release the welded appliance panel, allowing it to fall through the notch into the unloading chute. The unloading chute then collects the welded appliance panels, automatically unloading them without manual intervention, thus avoiding burns to workers' hands and potential safety accidents.

The left ends of the two clamping plates 5 extend to the top of the worktable 2. A notch 6 is opened through the right end of the upper end face of the base 1. A feeding groove 7 communicating with the notch 6 is fixedly connected to the lower end face of the base 1.

[0022] In this embodiment: During use, the appliance panel is placed on the workbench 2, positioned between two clamping plates 5. The two clamping plates 5 then move in opposite directions, causing their opposite sidewalls to abut against the outer wall of the appliance panel, thus clamping and fixing the appliance panel. The panel is then welded using an ultrasonic welding machine. After welding, the mounting strip 4 rotates 180 degrees, and in conjunction with the two clamping plates 5, flips the appliance panel above the notch 6. The two clamping plates 5 then move in opposite directions, releasing the welded appliance panel and allowing it to fall through the notch 6 into the unloading trough 7. The unloading trough 7 collects the welded appliance panels. The mounting strip 4 then rotates 180 degrees in the opposite direction, resetting the two clamping plates 5, and begins welding other appliance panels. This automatically unloads the newly welded appliance panels without manual intervention, preventing worker burns and potential safety accidents.

[0032] In this embodiment, the protective pad 16 can protect the appliance panel and prevent the clamping plate 5 from damaging the outer wall of the protective pad 16.

[0033] The working principle and usage process of this utility model are as follows: In use, the appliance panel is placed on the workbench 2, positioned between two clamping plates 5. Then, the second drive motor 15 drives the bidirectional screw 12 to rotate. The bidirectional screw 12, in conjunction with two sliders 13, moves the two clamping plates 5 in opposite directions, causing one side wall of each clamping plate 5 to abut against the outer wall of the appliance panel. This clamps and fixes the appliance panel. Then, an ultrasonic welding machine is used to weld the appliance panel. After welding, the first drive motor 14 drives... The worm gear 10 rotates, and the worm gear 10, together with the worm wheel 8, drives the mounting strip 4 to rotate 180 degrees.
