The slot bottom of the diversion trench 11 that steel band passes through, the diversion trench 11 is equipped with boss 12, and the boss 12 is along 11 length direction of diversion trench
Setting, and gap is equipped between the cell wall of 11 two sides of boss 12 and diversion trench, be respectively equipped in the gap of 12 two sides of boss for
Ensure 90 linear of steel band by the limit plate 13 of diversion trench 11, the setting of parallel 11 length direction of diversion trench of limit plate 13 and its with
The distance between boss 12 is adjustable, to adapt to various steel bands of different size.The length of the preferred adaptation diversion trench 11 of boss 12
Setting, identical as the length of diversion trench 11, steel band passes through water conservancy diversion on boss 12, between the limit plate 13 of two sides with linear type
Slot 11, avoids steel band from shifting, it is ensured that the accuracy of later period cloth glue.The top of the diversion trench 11 be equipped with by steel band leveling,
Prevent steel band from arching upward the limit for height baffle 14 of deformation, the limit for height baffle 14 is fixed on pedestal 10, is horizontally installed on diversion trench 11
Top.The front of limit for height baffle 14 is arranged in across 11 ground of diversion trench for electromagnetic heater 20 with temperature controller.Implement
In example, the electromagnetic heater 20 is set to 11 top of diversion trench, is evenly heated for steel band with can not contacting steel band.Use band temperature
The electromagnetic heater 20 of degree controller uses non-contacting mode for steel band heating, anti-can overheat, power saving safety, heating speed
Fastly, it can make the temperature of steel band that can be heated to 120 DEG C or more at 6 seconds or so, steel belt operating speed greatly mentions compared with prior art
Height, it is high in machining efficiency；Steel band self-heating reduces the loss of external heat transmitting, and the thermal efficiency is up to 85%-92% or more, section
Can be environmentally friendly, if being conducted heat using heater contacts, the thermal efficiency only has 50%-60%.The electromagnetic coil of electromagnetic heater 20 is kept
It is nice and cool, long service life.Electrothermal tube due to using resistance wire generate heat, although up to 300 degree or so of heating temperature, heat stagnation
It is larger afterwards, it is not easy accurate temperature controlling, resistance wire is easy to blow because of high temperature ageing；The heating of solution formula, electromagnetic heater 20 are connect using non-
It is contactless between steel band, it not will cause steel band pollution, according to contact heating, during steel band continuous service, and add
It rubs between hot device, influences heater life, steel band is be easy to cause to pollute, reduce the adhesive force of glue and steel band, or even have foreign matter
Be adhered to it is dry take, cause later period wiring board protrusion, scrap of the product, yields low.
In embodiment, the adjustable plate 131 vertical with limit plate 13, adjustable plate 131 are extended in the top of the limit plate 13
On be provided with 2 elongated through-holes 132 vertical with 11 length direction of diversion trench, correspond to the elongated through-hole 132 on pedestal 10 and be provided with
Distance between limit plate 13 and boss 12 is adjusted by elongated through-hole 132, adjustment hole for adjustment hole, the first adjusting bolt 133
Be connected on pedestal 10.
In embodiment, limit for height baffle 14 is connected on pedestal 10 by the way that the second bolt 141 is height-adjustable, on pedestal 10
Corresponding second bolt 141 is provided with bolt hole, and the limit for height baffle 14 is fixed at the upper end of the second bolt 141, adjustment
The height of limit for height baffle 14, applicable and different-thickness can be adjusted in the screw-in height of corresponding threaded hole for second bolt 141
Steel band.Likewise, the company that the electromagnetic heater 20 for being located at 11 top of diversion trench is height-adjustable by the second bolt 141
It connects, steel band biggish for thickness, the suitable backing plate of thickness is set between pedestal 10 and electromagnetic heater 20.The limit plate
13, limit for height baffle 14, electromagnetic heater 20 can also be used the prior art other common modes and connect.
The pedestal 10, boss 12 are preferably anti-static glass fiber plate matter, can also be other suitable bakelite plates, ceramic fibre
The high temperature resistants non-metallic material such as plate can prevent long-time heating from overheating or damaging.
It is as shown in Figure 1 the flow diagram of flexible circuit board teel band cloth glue, comprising the following steps:
Step 1 cleans the steel band to cloth glue；
Step 2 flattens the steel band after cleaning；
The steel band of leveling is carried out non-contact thermal to 120 DEG C of -140 DEG C of temperature using electromagnetic heater 20 by step 3；
Step 4 is pressed the steel band in step 3 with heat sensitive adhesive tape 40 using the pressing rubber roller 30 of interior heating.
Step 2 in 3, carries out the steel band using the leveling heating device of flexible circuit board teel band contactless
Heating.
Specifically, the method for carrying out steel band cloth glue using the device of flexible circuit board steel strip reinforced plate heating is as follows:
Firstly, according to the thickness and width of steel band 90, the position of adjustment limit plate 13, limit for height baffle 14, so that two pieces of limits
Between the plate 13 of position, steel band can be held just between limit for height baffle 14 and boss 12 pass through.Then steel band coiled strip is thoroughly cleaned,
It to output station is horizontally inserted into diversion trench 11 by input station, after limit for height baffle 14 is by the leveling of steel band coiled strip, through electromagnetism
Heater 20 non-contact thermal, then by after heating by steel band coiled strip and heat sensitive adhesive tape 40 commonly through pressing rubber roller 30,
Heat sensitive adhesive tape 40 is pressed together on steel band, last rewinding packaging.
In embodiment, the distance between limit plate 13 and steel band edge of two sides are adjusted between 0.5-1mm, makes steel band can
Pass through diversion trench 11 with successfully linear；The width of heat sensitive adhesive tape is 0.5-1mm fewer than the width of steel band, prevents pressing rubber roller 30
Glue is displaced to steel band edge and causes the more glue in edge when pressing, influences later product quality, can also save part adhesive tape, steel band 90
Be 4m/min by speed, the production efficiency than contact heating is enhanced about more than once.Through a large amount of it is demonstrated experimentally that pressing glue
Roller 30 be interior heating rubber roller, and press 30 surface of rubber roller temperature be 90 DEG C -130 DEG C between when, can enhance heat sensitive adhesive tape 40 with
The adhesive force of steel band 90.
Embodiment 2
As seen in figs. 5-6, embodiment 2 is substantially the same manner as Example 1, and difference is that the bottom plate 10 is equipped with two in parallel
Diversion trench 11, the boss 12, limit plate 13, limit for height baffle 14, electromagnetic heater 20 be adaptation setting two sets.It can be same
The cloth glue of two steel bands of Shi Jinhang, is greatly improved production efficiency.The quantity of the diversion trench 11 can also be set as needed as 3,
4,5 etc. several, the boss 12, limit plate 13, limit for height baffle 14, electromagnetic heater 20 are several sets of adaptation setting.
In embodiment 1,2, the slot bottom of the boss 12 and diversion trench 11 can be made into integration, and can also be to be fixed on diversion trench 11
The structure of slot bottom.
The electromagnetic heater 20 is to be symmetrically disposed on the top of diversion trench 11, two of lower section, can be heated simultaneously for steel band,
So that the upper and lower surface homogeneous heating of steel band and not contacting steel band.Fig. 7 is respectively provided with electromagnetic heater for the upper and lower surface in steel band
20 techniques heated for steel band.
