Electronic jacquard card drive board

Abstract

The invention discloses an electronic jacquard card drive board which comprises a drive circuit board, a bistable needle selection electromagnetic valve, an FPC flexible circuit, a data transmission interface and at least two fixed pins, wherein an electromagnetic valve fixed seat and the drive circuit board are fixed together through the fixed pins; the flat cable terminal of the FPC flexible circuit is connected with the drive circuit board through an FPC connector; the FPC connector is welded on the drive circuit board; and the data transmission interface comprises an interface plug and aninterface socket which are respectively vertically welded and fixed to the upper and lower surfaces of the drive circuit board. The bistable needle selection electromagnetic valve and the FPC flexible circuit on the electronic jacquard card drive board are fixed in a detachable way, and can be conveniently replaced when going wrong, thereby reducing the operation cost. The data transmission interface is convenient to disassemble and maintain, so that two electronic jacquard card drive boards can be connected together in a more stable way, thereby ensuring data transmission to be more accurate.

Description

technical field [0001] The invention relates to an electronic flower pillow driving board. Background technique [0002] In order to improve production efficiency, currently used looms often use electronic flower pillow drive boards to replace traditional paper perforated pattern boards to control the weaving of flower shapes. [0003] Such as Figure 1 to Figure 3 Shown is an existing electronic flower pillow drive board 10, including a push pin fixing frame 11, a guide frame 12, a drive circuit board 13, a frame 14, a bistable needle selection solenoid valve 15, a push pin 16, and an FPC flexible circuit 17 and data transmission interface 18. The bistable needle selection solenoid valve 15 is distributed on the drive circuit board 13 in a stepped manner, and is connected to the drive circuit board 13 through the FPC flexible circuit 17, and the two frames 14 are respectively pressure-welded to the drive circuit board 13 by pressure-welding plastic heads 14c sides.

AI Technical Summary

Problems solved by technology

[0014] The purpose of the present invention is to provide a new type of electronic flower pillow driving board. When the bistable needle selection solenoid valve and FPC flexible circuit on the electronic flower pillow driving board are damaged, the customer can replace it conveniently by himself. It saves costs and does not affect normal production operations. At the same time, it also overcomes the shortcomings of the existing electronic flower pillow driver board data transmission interface, such as easy aging, looseness, and poor contact, as well as insufficient frame strength.
