Description
Technical field
The present invention relates to a kind of electronic jacquard card drive board.
Background technology
The loom that uses at present often adopts electronic jacquard card drive board to replace traditional papery punching diamond plate to control weaving of colored shape for enhancing productivity.
As Fig. 1 to shown in Figure 3 is existing a kind of electronic jacquard card drive board 10, comprise the fixed mount 11 of pushing pin, guide bracket 12, drive circuit board 13, frame 14, bistable state needle selection electromagnetic valve 15, push pin 16, FPC flexible circuit 17 and data transmission interface 18.Bistable state needle selection electromagnetic valve 15 stepped being distributed on the drive circuit board 13, and be connected with drive circuit board 13 through FPC flexible circuit 17, two frames 14 respectively through pressure welding plastic cap 14c pressure welding in drive circuit board 13 both sides.
At publication number is that CN2639326 a kind of controls in the Electronic card of jacquard needle selecting and disclose a kind of bistable state needle selection electromagnetic valve.This bistable state needle selection electromagnetic valve is connected on the drive circuit board through the FPC flexible circuit.This bistable state needle selection electromagnetic valve is made up of electromagnetic valve holder, coil rack, coil, iron core and permanent magnet; Have horizontal biserial pilot hole and vertical special-shaped groove on the electromagnetic valve holder; One end of coil rack is provided with block, and the other end is provided with terminals, and a through hole is arranged in the middle of the coil rack; Iron core is installed in this through hole; Permanent magnet is installed on two faces unshakable in one's determination, and the excitation system that constitutes with permanent magnet unshakable in one's determination is fixed in the vertical special-shaped groove of electromagnetic valve holder, but coil rack and coil move relative to the iron core easy on and off.
Be typically provided with 6 reference columns on the electromagnetic valve holder of existing bistable state needle selection electromagnetic valve, drive circuit board is provided with 6 locating holes that cooperate with reference column, and wherein 4 reference columns are higher than other 2 reference columns.When electromagnetic valve is installed; Need earlier coil rack, coil, iron core and permanent magnet and electromagnetic valve holder to be assembled; Then the electromagnetic valve holder is fixed on the drive circuit board through 4 reference column pressure weldings; Form the pressure welding plastic cap at the drive circuit board lower surface, other 2 short reference columns play the role of positioning.
The winding displacement termination of the FPC flexible circuit 17 on the existing electronic jacquard card drive board is directly to be welded on the drive circuit board 13; Said frame 14 both sides top edges are respectively equipped with passive 3 small column 14a, also are provided with socket cap 14b in the rear and front end of frame; Its data transmission interface 18 uses winding displacement and bus bar connector to connect when the transfer of data that realizes between the electronic jacquard card drive board; 16 the plastic cap of pushing pin adopts cylindrical structural.
There are many defectives in above-mentioned electronic jacquard card drive board:
1, in actual use, the bistable state needle selection electromagnetic valve on the drive plate is damaged easily, but because this electromagnetic valve is to be fixed on the drive circuit board through adding thermocompression bonding; Be not easy to dismounting, and after disassembling, electromagnetic valve originally to be scrapped; Again load onto new electromagnetic valve, also need adopt bond technology, this all needs professional and special instrument to operate; Therefore, just have to return manufacturer's place under repair to the monoblock drive plate of damage electromagnetic valve.This has not only delayed the production operation of loom, has also increased the maintenance cost of enterprise.When the FPC flexible circuit was damaged, it was the same with the electromagnetic valve damage also to have to, and need the monoblock drive plate be returned manufacturer's place under repair.
If do not return maintenance, the monoblock drive plate all will be scrapped so, and this can cause great loss to enterprise.
2, the assembling of each parts of electromagnetic valve all needs manual work to operate, and the assembly work zone is very little, when the assembling permanent magnet; But their magnetic is very strong, is not easy to install, because above-mentioned this electromagnetic valve holder need be fixed on the drive circuit board through 4 reference column pressure weldings; The just necessary long enough of these 4 reference columns; And reference column is long, when the assembling permanent magnet, causes operational inconvenience just certainly will for the workman, causes work efficiency lower.
3, data transmission interface uses winding displacement and bus bar connector to connect, and its winding displacement in use has electric current to pass through, and is prone to heating; Increase along with service time; In the process of constantly heating and cooling, the distortion of winding displacement easy ageing causes to have loose contact and loosening easily shortcoming between winding displacement and the bus bar connector; So need dismantle and safeguard, change winding displacement frequently, reduce the operating efficiency of electronics flower pillow machine.Simultaneously, existing electronic jacquard card drive board data transmission interface adopts the mode of stitch welding to be fixed on the electronic jacquard card drive board, and winding displacement is often changed plug, also causes loose contact easily, more is not easy to the dismounting maintenance.
4, the front end of electronic jacquard card drive board frame short brink is not provided with the reinforcement step, at dismounting and maintenance process, and the drive plate fixed cylinder that fractures an easily 14b; Usually need be in real work with the work that stacks together of tens of electronic jacquard card drive boards, one side only is provided with small column and comes the support drive plate on the long limit of frame, because the strong point is too little, is easy to make electronic jacquard card drive board to intermediate recess.
5, existing electronic jacquard card drive board pushes pin that the through hole of reciprocating motion meeting and the fixed mount of pushing pin rubs in the through hole of fixed mount of pushing pin; The external diameter of the plastic cap of pushing pin can be more and more littler; Be easy to generate and rock; Rock the wearing and tearing that to send noise and the through hole that quickens the plastic cap of pushing pin and the fixed mount of pushing pin, be unfavorable for producing.
Summary of the invention
The object of the present invention is to provide a kind of novel electron jacquard card drive board; When the bistable state needle selection electromagnetic valve on the electronic jacquard card drive board and FPC flexible circuit are damaged; The client can be voluntarily, easily it is changed; Both provided cost savings, also do not influence the ordinary production operation, shortcomings such as that the winding displacement that has also overcome existing electronic jacquard card drive board data transmission interface simultaneously is prone to is aging, loosening, loose contact; And the frame insufficient strength, push pin plastic cap and the wear problem between the fixed mount through hole of pushing pin.
