Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, and Not all examples.

[0026] Such as figure 1 As shown, this embodiment provides an implementation of the slider, the slider 2 includes two double-layer grooves, each double-layer groove includes two grooves, one large and one small, and the large groove 3 and the small groove 4 In the same way, the large groove 3 is located above the small groove 4 .

[0027] In this embodiment, there are two double-layer grooves, which are distributed symmetrically.

[0028] In other embodiments, there may be only one double-layer groove, but this double-layer groove is preferably located in the middle of the slider, in order to m...

Abstract

This application relates to the tooling field of the micro-assembly process, in particular to an anti-tilt device for gold wire pressure welding fixtures in the micro-assembly process; the anti-tilt device includes matching sliders and plane slide rails; the plane The slide rail is provided with a large and a small double-layer groove, and the large groove is located directly above the small groove; the slide rail is provided with a number of first threaded holes, and the positions of the first threaded holes correspond to the positions of the double-layer grooves ;When in use, the slider is placed above the plane slide rail, and the screw is inserted from the small groove into the first threaded hole, and the head of the screw is stuck on the bottom upper surface of the large groove; this device can replace the gold wire welding fixture Zhongyuan's slider and slide rail can ensure the slider to slide freely, and at the same time, because the bottom surface of the screw head clamps the upper surface in the U-shaped groove of the slider, the tilting of the slider is limited.

Description

technical field [0001] The present application relates to the field of tooling for micro-assembly technology, in particular to an anti-lifting device for gold wire pressure welding fixing fixtures in the micro-assembly technology. Background technique [0002] The gold wire bonding process in the micro-assembly process requires a device to fix the shell to prevent the shell from shaking during the bonding process. According to the shape and size of different enclosures, the fixing fixtures need to be specially designed to match the fixing requirements. For the most conventional DIP package or SOP package ceramic shell, the fixing fixture generally adopts the simplest two-sided extrusion fixation, that is, one side of the ceramic shell touches a fixed stopper, and the other side is gradually squeezed by a slider. Press and fix, and at the same time, the bottom is focused on the matching base, thus forming the fixation of the ceramic shell. Because the chopper itself has hig...
