Problems solved by technology

[0006] If it is not returned for maintenance, the entire driver board will be scrapped, which will cause great losses to the company
[0007] 2. The assembly of all parts of the solenoid valve requires manual operation, and the assembly work area is very small. When assembling permanent magnets, they are very magnetic and difficult to install. Because the above-mentioned solenoid valve fixing seat needs to pass through 4 positioning If the pillars are fixed on the drive circuit board by pressure welding, the four positioning pillars must be long enough, and if the positioning pillars are too long, it will inevitably cause inconvenience to the workers when assembling the permanent magnet, resulting in low work efficiency

Abstract

The invention discloses an electronic jacquard card needle-selection drive board which comprises a drive circuit board, a bistable needle selection electromagnetic valve, an FPC flexible circuit and at least two fixed pins, wherein an electromagnetic valve fixed seat for the bistable needle selection electromagnetic valve is provided with locating posts; the drive circuit board is provided with locating holes which cooperate with the locating posts; the electromagnetic valve fixed seat is provided with pin holes which cooperate with the fixed pins; the drive circuit board is provided with fixing holes which cooperate with the fixed pins and the pin holes; the electromagnetic valve fixed seat and the drive circuit board are fixed together through the fixed pins; the FPC flexible circuit comprises a flat cable terminal and an FPC connector; the FPC connector is welded on the drive circuit board; and the flat cable terminal cooperates with the slot of the FPC connector. When the bistableneedle-selection electromagnetic valve and the FPC flexible circuit on the electronic jacquard card needle-selection drive board go wrong, a customer can conveniently replace bistable needle-selection electromagnetic valve and the FPC flexible circuit, thus the invention saves the cost and does not affect the regular production.

Description

technical field [0001] The invention relates to an electronic flower pillow needle selection driving board. Background technique [0002] In order to improve production efficiency, the current looms often use electronic flower pillow needle selection drive boards to replace traditional paper perforated pattern boards, and use bistable needle selection solenoid valves to control the weaving of flower shapes. [0003] For example, the publication number is CN2639326, an electronic cardboard for controlling needle selection of a jacquard machine. The electronic cardboard includes a bistable needle selection solenoid valve, which is connected to a driving circuit board through an FPC flexible circuit. The bistable needle selection solenoid valve is composed of a solenoid valve fixing seat, a coil frame, a coil, an iron core and a permanent magnet. The stopper, the other end is provided with a terminal, and there is a through hole in the middle of the coil frame. The iron core i...
