Description
Technical field
The utility model belongs to field of textile machinery, in particular to a kind of bimorph choosing of tricot machine piezoelectric jacquard
Faller gill.
Background technique
In textile machinery industry, jacquard flower's tricot machine uses more and more extensive.The driving piece of existing piezoelectric jacquard is
Bimorph, since the electrode structure of bimorph is similar to the structure of plate capacitors, at the edge of bimorph
It needs to carry out insulation processing.A kind of bimorph involved in patent document 1, patent document 2, bimorph, which removes, leans on copper
Foil one end reserves one section and remaining outside internal and external electrode extraction is used as to be coated with insulating layer entirely, as shown in Figure 3: must will be close to copper foil in advance
5 one end are pasted with protective film, then carry out dipping lacquer or spray painting operation, again remove protective film after paint curing, double piezo crystals
Piece front end is coated by insulating layer 8 completely.This process is complicated, needs to determine protective film according to the piezoelectric jacquard of different model
The length pasted, stock are difficult.But in actual use, the upper and lower side of only bimorph needs insulation processing, into
Row cladding completely is not necessarily to.
In addition, the bimorph of existing tricot machine piezoelectric jacquard all uses integral insulation to handle, in this way to height
Speed operating is very unfavorable, because running at high speed down, potsherd heat dissipation is difficult, be easy to cause high temperature failure or breakdown.
Patent document 1: Chinese utility model patent 201620876455.4.
Patent document 2: Chinese utility model patent 201820671570.7.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies of background above technology, provide a kind of bimorph selection piece, change
Become its insulation processing mode, solve the problems, such as high temperature failure, while be easier insulation processing, reduces production cost.
The technical solution of the utility model is: a kind of bimorph selection piece includes sley point, needle folder, double piezo crystals
Piece, insulated paint, wherein bimorph include middle layer, ceramic substrate, copper foil, interior electrode, external electrode, interior electrode enhancement layer,
External electrode enhancement layer, wherein insulated paint includes upper insulating layer, lower insulating layer, front insulation layer, rear insulating layer, it is characterized in that: upper exhausted
Edge layer is coated in the upper surface of bimorph, and lower insulating layer is coated in the lower surface of bimorph, and front insulation layer is coated in
The front surface edge of bimorph, rear insulating layer are coated in the rear surface edge of bimorph.Insulated paint is mainly protected double
The interior electrode of piezoelectric chip.
A kind of bimorph selection piece of the utility model changes its insulation processing mode, solves the problems, such as high temperature failure,
It is easier insulation processing simultaneously, reduces production cost；In addition, keeping selection piece installation more neat, consistency is more preferable, and appearance is more beautiful
It sees.

Specific embodiment
With reference to the accompanying drawing, the technical solution of the utility model is further described in detail.
As shown in Figure 1, Figure 2, Figure 4 shows: the utility model bimorph selection piece 10 includes bimorph 9, insulated paint
8, needle presss from both sides 11, sley point 12, and wherein bimorph includes upper and lower ceramic substrate 1, middle layer 2, external electrode 3, interior electrode 4, copper
Foil 5, external electrode enhancement layer 6, interior electrode enhancement layer 7, copper foil 5 is connected with interior electrode 4, as interior electrode leads to client.In interior electrode
With electrode enhancement layer can be printed on external electrode, by the interior electrode of two panels ceramic substrate towards substrate 2, in the manner described above by each layer
It bonds together.It is stained with needle folder 11 without copper foil bared end in middle layer 2, sley point 12 is inserted into the buckle of needle folder 11.
It is as shown in Figure 4, Figure 5: edge of 3 edge of external electrode of bimorph far from ceramic substrate 1 there are a certain distance,
The coincident at the edge of the width direction of interior electrode 4 and ceramic substrate 1, thus the interior electrode edge of upper and lower side be it is exposed
Outside.Insulated paint 8 includes upper insulating layer 17, lower insulating layer 18, front insulation layer 19, rear insulating layer 20, in which: upper insulating layer 17
Upper surface coated in bimorph 9, lower insulating layer 18 are coated in the lower surface of bimorph 9, and front insulation layer 19 coats
At the front surface edge of bimorph 9, rear insulating layer 20 is coated in the rear surface edge of bimorph 9.
As shown in Figure 6, Figure 7: the utility model bimorph selection piece 10 is installed to the rear solid of piezoelectric jacquard pedestal 13
Determine in slot 14, external electrode 3 is realized by way of conducting resinl with fixing groove after pedestal to be electrically connected and this field common one
Sample, bunch of cables 17 in connection, fills out casting glue 15, loads onto buttock line cover 14 and its accessory, assemble plug 16.
A kind of bimorph selection piece of the utility model changes its insulation processing mode, solves the problems, such as high temperature failure,
