Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, the present embodiment provides a wire clamp for a wire bonding machine, which includes a fixing base 10, and a piezoelectric ceramic element 11 is mounted on the fixing base 10. In order to realize the oscillation, one end of the piezoelectric ceramic element 11 is fixed, and the other end is provided with an oscillating portion 111. It should be noted that, the single piezoelectric ceramic element 11 belongs to the prior art, and when the piezoelectric ceramic element 11 receives power, the swinging portion 111 swings in one direction; when the power is off, the swing portion 111 returns to the original position.
A fixed arm 12 is further mounted on the fixed seat 10, one end of the fixed arm 12 is fixed, and the other end is provided with a fixed clamping jaw 121.
The wire clamp of the wire welding machine further comprises a moving arm 13, one end of the moving arm 13 is abutted to the swinging part 111, and the other end of the moving arm 13 is provided with a moving clamping jaw 131 matched with the fixed clamping jaw 121; the movable arm 13 is further provided with a swing fulcrum 14 on a side facing the fixed arm 12, which is in contact with the fixed arm 12.
Between the fixed arm 12 and the mobile arm 13 there is also provided an elastic element 15 for return. Optionally, the elastic element 15 is a tension spring.
Therefore, when the swing portion 111 swings, the moving arm 13 is pushed to swing about the swing fulcrum 14, so that the moving jaw 131 and the fixed jaw 121 are engaged to clamp and unclamp the lead.
According to the wire clamp of the wire bonding machine, the piezoelectric ceramic element 11 is used as the driving source, so that the wire clamp has the advantages of being smaller in size, lighter in weight, higher in response speed, higher in wire bonding precision, higher in resolution, lower in power consumption and the like; and because the fastener is lighter, reduced holistic inertia of motion, provided the stability of fastener structure.
It should be noted that the swing portion 111 and one end of the moving arm 13 are disposed in abutment rather than being fixedly connected or rotatably connected, so that the swing of the moving arm 13 can be smoother and the response speed can be faster.
