Embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 2, for a kind of anisotropic conductive film attaches the machine structural representation, form by electric control box 1, work control box 2, feeding control motor 3, pressure head cylinder 4, guide wheel 5, worktable 6, pressure head 7, cutting knife 15 and stripping rod 16, width adjustor 17, length adjuster 18, stepper motor 19.

Feeding control motor 3 is connected with guide wheel 5, stripping rod 16, width adjustor 17, length adjuster 18 and stepper motor 19 by adhesive tape, worktable 6 is located at the lower end that has pressure head cylinder 4 pressure heads 7 moving up and down, band pressure head cylinder 4 pressure heads 7 moving up and down are located in the work control box 2, stepper motor 19 connects electric control box 1, and cutting knife 15 is located on the worktable.

As shown in Figure 3, be the electric control box structural representation, between the programmable controller PLC of electric control box 1 and stepper motor 19, impulse controller, circulation divider and amplifier be installed.

As shown in Figure 4, for anisotropic conductive film attaches machine attaching method process flow diagram, the programmable controller PLC of electric control box 1 usefulness is the FX of Mitsubishi on the big rugged anisotropic conductive film attaching machine ON-60MT and spread F X ON-16EYT, by revising the PLC program, ladder diagram with MIT programs, operate in the programmable controller PLC of electric control box 1, corresponding umber of pulse is set on impulse controller, start cylinder 5, lifting worktable 6 makes the glass screen of pressure head 7 lean on vacuum suction on worktable 6; , start the control that stepper motor 19 is realized the step motor rotating and the anglec of rotation; Reach the length of the control ACF that attaches, the angle that corresponding stepper motor rotates also is the length that correspondence is drawn ACF glue.

Anisotropic conductive film attaching machine to the basic demand of stepping motor 19 is:

A. stepping motor 19 reaches in startup rapidly under the control of electric pulse, rotating, stall and carry out rotational speed regulation in very wide scope.

B. in order to improve precision, require the displacement of a pulse correspondence little, and want accurately, evenly.This just requires, and stepper motor 19 step pitches are little, stepping accuracy is high, must not lose the step or the step of getting over.

C. action fast.It is fast promptly not only to start, stop, reverse, and can turn round to raise labour productivity by continuous high speed.

D. it is big to export torque, can directly drive multiple carrying.

Angular displacement θ or displacement of the lines amount s are proportional to pulse number k;

Rotation speed n or linear velocity v are proportional to pulsed frequency f;

Drive preposition runner control ACF by stepper motor 19 rotation angle displacements and accurately transmit, the more little precision of step angle is high more,

θ=360°/Z×N

Wherein, θ: step angle; Z: the rotor number of teeth; N: operation umber of beats; N=km, k=1, m=2, m are the number of phases; When pulsed frequency=1/k free running frequency, rotor can produce vibration even step-out, so need contain mechanical damper.

For improving performance, promptly improve motor torque as far as possible, reduce motor and load inertia, so need to adopt the doublebeat system allocation scheme of heterogeneous energising.

Now use stepper motor Vexta0.18 °/stepPK264A2-SG10 instead, control is to guarantee precision, and the step motor control precision is in the 50 μ m.Stepper motor 19 is selected 0.18 °/step for use, according to the ACF length difference that difference attached of product, starts the control that stepper motor 19 is realized the step motor rotating and the anglec of rotation; The cutting of ACF was finished in action downwards again after control cutting knife 15 made progress; The attaching of ACF is finished in vertical motion again after control pressure head 7 descends; Retreat again after the control stripping rod advances, finish peeling off of ACF; The ACF step motor shaft changes, and reaches the purpose of the control ACF length that attaches at last.

As shown in Figure 5, be stepper motor impulse controller panel synoptic diagram, on the panel, 20 for the terminal input shows, 21 are the program schema demonstration, 22 are the test pattern demonstration, 23 is data presentation, and 24 is mode button, and 25,26 for controlling pressure head 7 declines or vertical motion, control cutting knife 15 Action Button up or down, 27 for being provided with button, and the button by operation step motor control panel can be realized control to the step motor rotating and the anglec of rotation like a cork via servo module.

By big rugged ACF being attached the transformation of machine, the precision that ACF attaches length and sticking position can be controlled in the 50 μ m, has met the technological requirement of producing, and has transformed seven altogether, and has put into production.
