Ultrasonic welding device for lithium battery

Abstract

The invention discloses an ultrasonic welding device for a lithium battery. The ultrasonic welding device is characterized by structurally comprising an upper fixed base, a connecting tube, a supporting rod, a connecting base, an operating table, a functional panel, a housing, the lithium battery, a welding head and a welding tube, wherein the upper fixed base is arranged on the top of the supporting rod; the connecting tube is arranged at the right side of the bottom of the upper fixed base; the connecting tube is mechanically connected with the upper fixed base; the connecting base is arranged on the top of the supporting rod; the supporting rod is fixedly connected with the connecting base; the operating table is arranged on the top of the housing; the operating table and the housing are an integrated structure; the functional panel is mechanically connected with the operating table; the lithium battery is mounted inside the housing; the lithium battery is mechanically connected with the housing; the welding head is mounted on the bottom of the welding tube; the welding tube is arranged on the bottom of the connecting tube; and the welding tube is fixedly connected with the connecting tube. The ultrasonic welding device has the beneficial effects that: a polar post, a safety valve, a negative electrode plate, a positive electrode plate, a U-shaped diaphragm and a C-shaped diaphragm are arranged, so that a pollution value can be greatly reduced, the service life of the lithium battery is long, frequent replacement does not need, and economical efficiency and practicability are high.

Description

technical field [0001] The invention is an ultrasonic welding device for a lithium battery, which belongs to the field of ultrasonic welding equipment. Background technique [0002] Ultrasonic technology is widely used in plastic welding, metal welding and other processing fields, while ultrasonic plastic welding machines need to adjust the welding height of the head when welding, and when the head is lowered, it is affected by the frame assembly, the verticality of the column and the time of pressing down. Affected by factors such as the slight backward tilt of the machine head after the thrust of the cylinder, the ultrasonic welding head is not parallel to the welding line of the welded part. At present, most ultrasonic welding machines use the method of installing four screws on the welded mold To adjust the welding line, but this kind of processing method needs to install a horizontal device on the ultrasonic mold every time an ultrasonic mold is made, which makes the ec...
