The second direction is at an angle of 45° to the first direction, and the third direction is perpendicular to the first direction.

[0033] The second positioning portion 200 includes a second bottom mold 210, a magnet 220, and a pressing plate 230. The magnet 220 is located on one side of the second bottom mold 210 and is spaced apart from the second bottom mold 210. The pressing plate 230 can be adsorbed on the surface of the magnet 220 and cover the second bottom mold 210.

[0034] The bottom of the accommodating groove in the first bottom mold 110 is not lower than the top surface of the second bottom mold 210 .

[0035] It can be understood that when the positioning device is applied to the ultrasonic welding equipment, the first direction, the second direction and the third direction are all located on the horizontal plane.

[0036] Specifically, the slide groove 111 is a T-shaped groove, and the shape of the slider 120 is also T-shaped, so that the slider 120 is always in contact with the first bottom mold 110 when sliding along the slide groove 111; the fastener is a screw, and the position of the slider 120 is fixed by tightening the screw, thereby achieving the fixation of the position of the first limit member 130, achieving the purpose of adjusting the width of the accommodating groove, and is suitable for the ultrasonic welding requirements of aluminum foils of different widths.

[0037] During use, first adjust the position of the first limiter 130 and the width of the accommodating groove, then place the oblique edges of the two aluminum foils opposite each other, and place the aluminum foils in the accommodating grooves respectively, while the oblique edges of the two aluminum foils are opposite each other and overlapped on the second bottom mold 210; press the pressing plate 230 on the oblique edges, and use the magnet 220 to fix the pressing plate 230 by magnetic attraction, and press and fix the area where the oblique edges overlap, so as to facilitate the welding of the acoustic resistance component 800 to the area where the oblique edges overlap, thereby improving the welding accuracy and welding quality.
