Description

[0002] An ultrasonic welding machine generates high-voltage and high-frequency signals of 20KHz (or 15KHz) by a generator. Through a transducer system, the signals are converted into high-frequency mechanical vibrations and applied to the workpieces. The temperature at the interface is increased by the friction between the workpiece surfaces and between molecules. When the temperature reaches the melting point of the workpiece itself, the interfaces of the workpieces are quickly melted, and then the voids between the interfaces are filled. When the vibration stops, the workpieces are cooled and shaped under a certain pressure simultaneously, thus achieving high-quality welding.

The lifting mechanism 2, the product positioning seat 3, and the machine table 11 are installed inside the cabinet 8. The welding head 1 is installed on the lifting mechanism 2, and the welding head 1 is located above the product positioning seat 3. A wire clamping mechanism 4 is installed on one side of the product positioning seat 3. A machine table 11 is provided on one side of the product positioning seat 3. A wire harness clamping mechanism 7 is slidably connected to the machine table 11. A single-rod cylinder 5 is installed inside the machine table 11. The piston rod end of the single-rod cylinder 5 is connected to a force sensor 6. The force sensor 6 is connected to a connecting plate. The wire harness clamping mechanism 7 and the touch plate are fixed on the connecting plate. A starting point sensor 9 and an end point sensor 10 are provided on one side of the touch plate. The cylinder body of the single-rod cylinder 5 is connected to a gas source through an electro-hydraulic proportional valve. The lifting mechanism 2, the wire clamping mechanism 4, the single-rod cylinder 5, the force sensor 6, the wire harness clamping mechanism 7, the starting point sensor 9, and the end point sensor 10 are all electrically connected to a PLC.

[0026] The wire clamping mechanism 4 includes a finger cylinder and clamping plates. Two clamping plates are respectively fixed on the two fingers of the finger cylinder.

[0027] The wire harness clamping mechanism 7 includes a parallel cylinder and clamping blocks. Two clamping blocks are respectively fixed on the two fingers of the parallel cylinder.

[0028] Combined with the atta Figure 2 ched drawings and the atta Figure 3 ched drawings shown, a cover plate 12 is hinged on the cabinet 8. The two sides of the cover plate 12 are respectively hinged on the piston rods of two single-rod cylinders 13. The cylinder bodies of the single-rod cylinders 13 are hinged inside the cabinet 8.

[0029] When the piston rods of the single-rod cylinders 13 extend, they can push the cover plate 12 to open outwards. When the piston rods of the single-rod cylinders 13 retract, they can pull the cover plate 12 to cover again.

[0030] A protective cover 14 is slidably connected to the cabinet 8. A lifting single-rod cylinder 15 is fixed inside the cabinet 8. The piston rod of the lifting single-rod cylinder 15 is connected to the protective cover 14.

[0034] The working mode of this application is as follows: First, place the terminal and the wire harness end on the product positioning seat 3, and both the wire clamping mechanism 4 and the wire harness clamping mechanism 7 clamp the wire harness. The wire harness passes through the wire grooves of the front and rear wire guide plates 16.

[0035] Then, the lifting mechanism 2 drives the welding head 1 to move downwards to weld the terminal and the wire harness together. Then the wire clamping mechanism 4 releases the wire harness, and the two clamping plates of the wire clamping mechanism 4 block the terminal. At this time, the PLC controls the electronic proportional valve to start, and the electronic proportional valve controls the single-rod cylinder 5 to push the wire harness clamping mechanism 7 to move horizontally forward with a set thrust, thereby pulling the wire harness. At the same time, the force sensor transmits the thrust signal to the PLC, and the PLC judges whether the current thrust meets the preset value. If during the movement, the touch plate triggers the end sensor 10, and the end sensor 10 transmits the signal to the PLC, it is judged that the wire harness terminal is unqualified. If the touch plate does not contact the end sensor 10 within the set time, it is judged that the wire harness terminal is qualified.
