With the arrival in electronic industry epoch, the equipment for producing electronic product and manufacture part flourishes.Film laminator is
Specific PCB (printed circuit board (PCB)) dry film is hot-pressed onto the equipment on pcb board by one kind, and film to be pressed dry is erected on press mold machine equipment,
When pcb board passes through film laminator, two pressing wheels arranged up and down make dry film close pressure by the pressure and temperature of pressing wheel
It is attached to pcb board surface.
The dry film that press mold process requirements press against on monoblock pcb board surface is neat, uniform, is not allow for any bubble and wrinkle
Pleat produces, this require up and down pressing wheel to pressure caused by pressure on pressing wheel length direction consistent, pressing wheel glue-line
Thickness, hardness and temperature are appropriate, and only accomplishing the above, some just can guarantee that press mold quality.
At present, the hot pressing wheel on PCB pressed film equipments, all it is to place heater, each temperature spread of glue surface from endoporus
Greatly to 6 DEG C~15 DEG C, temperature fall is too big, influences press mold effect.Pressing wheel on the various brand film laminators that PCB enterprises use,
Common disadvantage causes bad plate face to be lost very when temperature is unstable or drop senior general has a strong impact on being bonded for film and circuit plate face
Greatly.
It is not difficult to find out, prior art also has the defects of certain.
The content of the invention
The purpose of this utility model is to overcome drawbacks described above of the prior art, there is provided a kind of temperature control pressing wheel, sets
Temperature controller electric eye, its uniformity of temperature profile, the glue surface temperature difference are smaller, and heat conduction is fast and temperature stabilization, temperature change are empty by environment
Gas influences very little.
The utility model is achieved to realize above technical purpose using following technical scheme：
A kind of temperature control pressing wheel, including body for press mold, be arranged in body and be provided with temperature controller electricity
The thermal source of eye and the glue surface for being coated on the control that temperature controller electric eye is provided with outside body, the heat source temperature controller electric eye
Electrically connected with glue surface temperature controller electric eye.
Further technical scheme is：The heat source temperature controller electric eye is with glue surface temperature controller electric eye by leading
Line electrically connects with outside control cabinet.
Further technical scheme is：Be provided with the tube wall of the body it is multiple longitudinally through through hole, it is described to pass through
The through hole worn is evenly distributed in tube wall in heat；The through hole is embedded in heat conducting pipe, and heat conducting pipe is wrapped with heat conducting pipe material
Metal net, the heat conducting pipe are hollow structure, are injected with heat-conducting medium inside it.
Further technical scheme is：The through hole is at least six with heat conducting pipe in cylinder, the number of openings.
Further technical scheme is：The end surfaces of tube wall two of the body are provided with screw hole, the screw hole count
Amount is at least 6.
Further technical scheme is：The both ends porch of the through hole is provided with heat resistanceheat resistant sealing ring.
Further technical scheme is：The body also includes spindle nose, and body is screwed with spindle nose and is connected.
It is using beneficial effect caused by above-mentioned technical proposal：Temperature change is soft, sets temperature controller electric eye to be
Glue surface temperature stabilization, avoid pressing wheel hull-skin temperature rise sharply and rapid drawdown, the temperature difference for the pressing wheel glue surface each point for being is little,
Uniformity of temperature profile, the phenomenon that press mold thickness will not be caused to differ.
