Abstract

The utility model discloses a piezoelectric Jacquard element of a novel warp knitting machine, comprising two piezoelectric ceramic chips and a substrate, wherein the two piezoelectric ceramic chips are respectively bonded on the two surfaces of the substrate, and a bow-shaped conductive band or an arc-shaped conductive band is attached to the substrate. Compared with the prior art, the piezoelectric Jacquard element of the novel warp knitting machine has the following advantages: the influence of a linear copper film on the bending of the substrate can be effectively removed due to the arrangement of the bow-shaped conductive band or the arc-shaped conductive band from the analysis of mechanical structure; the area of the conductive band on the substrate is increased and the conductivity of the substrate is enhanced; and the bonding stress is uniform and the bond is not easy to rupture.

Description

Novel warp knitting machine piezoelectric jacquard element

Technical field

The utility model relates to piezoelectric ceramic tricot machine technical field, particularly a kind of novel warp knitting machine piezoelectric jacquard element.

Background technology

Tricot machine piezoelectric jacquard element is used for the skew of Jacquard sley point on the control tricot machine.It is comprised of two piezoelectric ceramic wafers, is isolated by substrate between them.Piezoelectric ceramic wafer through hyperpolarization adds that voltage can produce the deformation of shrinking and upholding, and meanwhile, for transfer overvoltage, has adopted to have fine elasticity and conductive electrode.Switching by the both sides contactor, both sides at the piezoelectric jacquard element replace making alive, piezoelectric ceramic produces deformation, so that sley point is offset left or skew to the right, because the piezoelectric ceramic effect is as the electric capacity, the piezoelectric jacquard element can remain on its deviation post, by needle gage of current impulse control skew.

Glass mat commonly used is as substrate in the existing piezoelectric jacquard element, its insulating properties, bent toughness and and ageing resistace all can satisfy the piezoelectric jacquard element to the requirement of substrate, but in the actual product design, the be everlasting two sides of glass mat is adhered to the copper film and is made the wire extraction electrode, such copper film is designed to linear pattern and covers on the glass mat face, because linear pattern copper film is equivalent to the muscle on the glass-fiber-plate, affects the bending of substrate.

Summary of the invention

In order to overcome defects, the utility model provides a kind of novel warp knitting machine piezoelectric jacquard element.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of novel warp knitting machine piezoelectric jacquard element, comprise piezoelectric ceramic wafer and substrate, piezoelectric ceramic wafer is bonded on the face of substrate, and described conductive strips are arc conductive strips or arc conductive strips.

The beneficial effects of the utility model are: the utility model contrast prior art has following remarkable advantage:

1. from the mechanical structure analysis, the impact that bending causes on substrate of linear pattern conductive strips can be effectively removed in arc conductive strips or the design of arc conductive strips;

2. strengthen on-chip conductive strips area, strengthened the conductivity of substrate;

3. so that bond stress is even and bonding is difficult for breaking.
