Handheld ultrasonic spot welder and operation method

Abstract

The invention relates to a handheld ultrasonic spot welder and an operation method. A host machine is of an integrated design comprising a probe and an ultrasonic vibration system; the ultrasonic vibration system comprises an electronic tracking frequency converter, an ultrasonic transducer and an amplitude-change pole; the amplitude-change pole is arranged at one end of the host machine; an aviation plug is arranged at one end, far way from the amplitude-change pole, of the host machine; a welding head is arranged at one end, far away from the host machine, of the amplitude-change pole; a bayonet and a connecting screw are connected to the outer side of the amplitude-change pole; a fastener device is arranged at one end close to the host machine; the amplitude-change pole and the fastenerdevice are in butt joint through a connecting screw; the fastener device is connected with a piezoelectric ceramic piece close to one end of the host machine; and the electrode plate is connected with the piezoelectric ceramic piece through a special fastening bolt for a high-strength transducer. According to the handheld ultrasonic spot welder, a cable wire at one end of the host machine is supported through a support sleeve made of an insulating rubber material, and through grooves distributed at equal intervals, the support sleeve can conveniently drive the cable wire to bend at a certaininclined angle, so that the cable wire is prevented from being wound with a hand part, and the handheld ultrasonic spot welder is convenient to use.

Description

technical field [0001] The invention relates to the technical field of welding of plastic products and mask ear loops, in particular to a hand-held ultrasonic spot welding machine and an operation method. Background technique [0002] The handheld ultrasonic welding machine can be used for welding thermoplastic materials, and the welding head can be replaced according to different welding processes, and is used for riveting welding, spot welding, embedding, cutting, etc. The hand-held ultrasonic welding machine can replace different ultrasonic welding heads according to the size of the riveting point of the product to be welded and the welding requirements. The cost is much lower than that of the special-purpose ultrasonic welding machine for automobile door panels, which is convenient to meet the needs of customers. The current ultrasonic spot welding machine Ultrasonic spot welding machines are bulky, separated, and the circuit system is backward. For this reason, we hope ...

AI Technical Summary

Problems solved by technology

[0003] Although there are many types and quantities of hand-held ultrasonic spot welding machines currently on the market, ultrasonic spot welding machines have such disadvantages: ultrasonic spot welding machines are inconvenient to carry and use outdoors due to their large size and separate configuration, and the circuit system is backward. Therefore, it is necessary to improve the current ultrasonic spot welding machine
