Embodiment 1

[0060] A high-precision automatic winding device for a fuel injector, comprising a tension control mechanism 1, a main winding mechanism 2, a coil tap winding mechanism 3; a control system; the control system is connected with the tension control mechanism 1 and the main winding mechanism respectively 2. The coil tap winding mechanism 3 is connected. in:

[0061] The tension control mechanism 1 is used to keep the tension of the wire stable during the winding process, so that the coil can be wound neatly while avoiding loosening or breaking of the winding. This tension control mechanism 1 comprises electronic tension device 101, guide wheel 102, and electronic tension device 101 is installed on the pay-off frame 4, and the tension control precision of this electronic tension device 101 is ± 0.5g, and electronic tension device 101 and control system The input and output ends are connected; the guide wheel 102 is installed on the top of the coil tap winding mechanism 3 for guid...

Embodiment 2

[0066] A method for high-precision automatic winding of a fuel injector, the method comprising the following steps:

[0067] S1. Waiting to start

[0068] After the wire is stably adjusted by the electronic tensioner 101 of the tension control mechanism 1 (the tension control accuracy is ±0.5g), it passes through the guide wheel 102 and the wire arranging needle 2011 of the wire arranging mechanism 201 in sequence, and then winds up to the thread breaking mechanism 303 On the pin 3031 of the fuel injector, the high-precision automatic winding device of the fuel injector is waiting to start production;

[0069] S2. The first tap of the wound coil

[0070] When the bobbin is sent to the station and the control system receives the start command, the control system controls the lifting mechanism 301 of the coil tap winding mechanism 3 to move up and down and the left and right moving mechanism 302 of the thread end to move left and right, and wind the terminal at one end of the b...

Abstract

A high-precision automatic wire winding device for fuel injector and its method relate to an automatic wire winding device and its method. The device comprises a tension control mechanism, a main wirewinding mechanism, a coil tap winding mechanism and a control system. The control system is respectively connected with a tension control mechanism, a main winding mechanism and a coil tap winding mechanism. The method comprises the following steps: step S1. Waiting starts, step S2. Winding the first tap of the coil, step S3. Winding the coil, step S4. Winding the second tap of the coil, step S5.Breaking the coil, and step S6. Removing the coil. As that tension control mechanism, main winding mechanism, Cooperation between that coil tap win mechanism and the control system, The invention canaccurately control the speed and winding position of the coil in the winding process, so that the winding wire is evenly distributed, the consistency is good, the wire tightness in the winding process can be ensured to be suitable, the requirements of the high-precision metering fuel injector for the winding wire are met, and the coil has the characteristics of good precision, high efficiency andhigh qualified rate, and is easy to be popularized and used.

Description

technical field [0001] The invention relates to an automatic winding device and method thereof, in particular to a high-precision automatic winding device and method for a fuel injector. Background technique [0002] In order to ensure the consistency of product performance, high-precision metering injectors have higher requirements on the winding device, not only to ensure that the tightness of the wire during the winding process is appropriate, but also to ensure that the coils are arranged neatly and orderly, and the coil inductance, resistance, etc. The consistency of key parameters makes the electromagnetic force, opening time and closing time of the injector meet the design requirements. However, at present, domestic fuel injector manufacturers are mainly winding manually, which has disadvantages such as poor consistency, poor precision, and low efficiency, and cannot meet the winding requirements of high-precision metering injectors. Contents of the invention [00...
