Example Embodiment

[0015] Such as figure 1 , figure 2 with image 3 As shown in common, the welding wire pressing plate includes a pressing plate body 1, the bottom of the pressing plate body 1 is a pressing surface 11, the two sides of the pressing plate body 1 are respectively provided with mounting parts 2 for connecting with the machine, and the pressing plate body 1 is provided with a welding The wire window 3 is provided with several slitting ribs 31 arranged in parallel. The slitting ribs 31 divide the welding wire window 3 into a number of welding areas 32. The slitting ribs 31 extend along the surface of the pressure surface 11 The two sides extend and form convex ribs 4 protruding from the material pressing surface 11, and two adjacent ribs 4 and the material pressing surface 11 jointly enclose an accommodating area.

[0016] Since there are several undivided small PCB boards neatly arranged on the whole PCB board, there are gaps between these small PCB boards. When wire bonding, the whol...

Abstract

The invention discloses a weld line pressure plate, which comprises a pressure plate body. The bottom of the pressure plate body is a material pressing surface, mounting portions used for being connected with a cabinet are disposed on two sides of the pressure plate body respectively, a weld line window is arranged on the pressure plate body, a plurality of slitting ribs are parallelly disposed on the weld line window and divide the weld line window into a plurality of welding areas, the slitting ribs extends along the surface of the material pressing surface to two sides of the material pressing surface and form convex ribs protruded on the material pressing surface, and each two adjacent convex ribs and the material pressing surface jointly encircle to form a holding area. The welding window is divided into the welding areas by the slitting ribs, acoustic resistance is high when ultrasonic welding is carried out in relatively small areas, ultrasonic energy is quickly gathered for heating and cannot be released easily, and accordingly ultrasonic welding quality is improved. In addition, due to the convex ribs, each welding elements is positioned in the corresponding holding area jointly encircled by the corresponding two convex ribs and the material pressing surface, the welding elements cannot be damaged easily, and the weld line pressure plate brings convenience for welding and prevents defective weld lines.

Description

technical field [0001] The invention relates to a welding wire fixture, in particular to a welding wire pressing plate. Background technique [0002] The welding wire pressing plate is mainly used for fixing and leveling the PCB board during wire welding, so as to ensure that the PCB board is under stress during wire welding, so that the effect of ultrasonic waves can be released more completely. [0003] The existing welding wire pressing plate has a large welding wire window in the welding area. During the wire welding process, the PCB board in the window is easily deformed and appears suspended, causing part of the ultrasonic energy to be released, and the welding effect is not ideal; now The bottom surface of some welding wire pressing plate is a smooth plane, and the phenomenon that the product contacts the bottom surface of the pressing plate when the welded product is deformed causes the welding wire to be defective. Therefore, the wire bonding plate needs to be impr...
