Embodiment, belongs to the scope of protection of the invention.
As depicted in figs. 1 and 2, the present invention proposes a kind of stability Design mechanism of pressure head long 13, including power drive group
, to adjusting part and the executive module of pressure head 13, power drive assem is by extension spring 4 with X/Y to tune for part, guidance set, X/Y
Section component connection, the executive module of pressure head 13 is located at lower sections of the X/Y to adjusting part, and guidance set is located at side.
Power drive assem includes cylinder 1 and cylinder mounting seat 2, and cylinder 1 is fixed in cylinder mounting seat 2, and cylinder is installed
2 both sides of seat are provided with prominent screw, and one end of extension spring 4 is fixed on the screw, and cylinder mounting seat 2 is fixed on vertical bottom
On plate 3.
Guidance set includes the buffer 5 being fixed on base plate 3 and accurate slide rail 7
X/Y includes X to adjustment seat 6 and Y-direction adjustment seat 8 to adjusting part, and X is fixed on Y-direction adjustment seat 8 to adjustment seat 6
Top, X is used to adjust X to regulation to adjusting screw and lock-screw, adjusting screw is equipped with adjustment seat 6 and Y-direction adjustment seat 8
The position of seat 6 and Y-direction adjustment seat 8, lock-screw is used to lock the X adjusted after good position to adjustment seat 6 and Y-direction adjustment seat 8.
X/Y is separated to adjusting part with calandria 12, completely cut off heat transfer of the heat of pressure head 13 to adjustment mechanism.Therefore, pressure head 13
Depth of parallelism stability is improved, and greatly reduces depth of parallelism adjustment frequency.An adjustment axis, and zero are respectively used in XY both directions
There is built-in back-moving spring, simple structure is easily adjusted, and improves the depth of parallelism regulated efficiency of pressure head 13 between part.
The executive module of pressure head 13 includes pressure head 13, calandria 12, thermal insulation board 11, heat insulation 10 and the radiating block 9 of strip,
The number of radiating block 9 is 2, is respectively provided at the two ends of Y-direction adjustment seat 8, and heat insulation 10 is fixed on the lower section of radiating block 9, thermal insulation board
11st, calandria 12 and pressure head 13 are fixedly connected sequentially from top to down.Because pressure head long 13 is heavier, radiating block 9 is adopted in the middle of part
With the structure of split, to mitigate the weight of whole pressure head 13, stability of the pressure head long 13 to this pressure of large scale IC is realized.Pressure head
13 insulating portions employ double thermal insulation structure, and internal with air heat dissipation channel, effectively prevent calandria 12 to slide rail
Heat conducts, it is ensured that the kinematic accuracy of pressure head 13, extends the life-span of slide rail.Pressure head 13 is using high temperature resistant, wear-resistant, expansion
The small ceramic material of coefficient, it is ensured that stability of the pressure head 13 in heating process, improves Product Precision.
Present invention additionally comprises radiator fan 14, radiator fan 14 is screwed in cylinder mounting seat 2.
The setting temperature of pressure head 13 is 300 DEG C.
Operational process of the invention:
1.1 operation preparations：Adjustment pressure head 13 press against the depth of parallelism of platform with LCD.Dextrorotation or left-handed Y-direction adjustment seat 8
On adjusting screw, Y-direction adjustment seat 8 can band dynamic head 13 do corresponding Y-direction together and swing, dextrorotation or left-handed X are in adjustment seat 6
Adjusting screw, X to adjustment seat 6 can band dynamic head 13 be corresponding X together to swing.Be press against in LCD and pressure-sensitive is placed on platform
Paper, and decline pressure head 13, is pressed on pressure-sensitive paper, and the time is less than 0.3 second, will pressure head 13 rise.According to the color of pressure-sensitive paper
Situation of change, the adjusting screw in difference turn X adjustment seats and Y-direction adjustment seat 8.Pressure head 13 press against platform with LCD can be correspondingly
Tend to parallel.Pressure-sensitive paper is placed on it press against platform again, pressure head 13 is declined, the color change of pressure-sensitive paper, root are observed again
According to color change situation, the depth of parallelism again to pressure head 13 is adjusted according to the method described above.Until the color of pressure-sensitive paper is in pressure
Uniformity in the range of first 13.Then, locking X is to adjustment seat 6 and the lock-screw of Y-direction adjustment seat 8.
1.2 regulation magnitude of back pressure.Pressure on IC is acted on, it is necessary to simultaneously to cylinder 1 in order to accurately control pressure head 13
The different source of the gas of both sides supply pressure, control pressure head 13 to act on the power on IC using both pressure differentials.Cylinder 1 is enterprising
The pressure of gas port is referred to as main pressure, and the pressure of lower air inlet is referred to as back pressure.First by main pressure regulation to zero pressure, then, progressively
The precise pressure regulating valve of turn back pressure, promotes the mechanism of pressure head 13 so that pressure head 13 can be rested in stroke range with lower on hand
Optional position is motionless, and now, pressure head 13 can not automatically decline because of gravity.It is exactly now the back-pressure for needing.Due to the hair
It is bright to have used the split-type design of radiating block 9, the weight of the mechanism kinematic part of pressure head 13 is significantly reduced, therefore, it is possible to cause pressure head
13 is more stable when large scale IC is pushed.
1.3 heat up pressure head 13, until reaching the setting temperature of pressure head 13, (displays temperature of temp controlled meter is about 300
℃)。
1.4 operational processes.When LCD reaches working position, cylinder 1 can decline under program, by slide rail band dynamic pressure
First 13 are moved together, until the working face of pressure head 13 is fallen within the IC or FPC of LCD, and continues to keep the constant pressure of a period of time, IC is protected
The time for holding constant pressure is generally 8 seconds, and FPC is kept for the time of constant pressure be generally 12 seconds.Then pressure head 13 rises.Complete IC or FPC
Bonding (BONDING) on LCD.
The stability Design mechanism of pressure head long 13, can be non-using the structure connected by spring between cylinder 1 and slide rail
In the case that ideal line is moved, the self-adapting float of pressure head 13, and flying height is adjustable, self adaptation sensitivity is high.This spring is also
Serve as the effect of mechanical vibration damping, in the moment that pressure head 13 is contacted with LCD, the position of pressure head 13 will rapidly shift in Z-direction, this
When telescopic spring compensate deviation post rapidly, it is and rapid steady, hence it is evident that to reduce the shock loading for acting on glass substrate.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
