The utility model discloses a press mold wheel temperature variation is soft, and the temperature passes to press mold wheel surface via the conduction oil again, and the cost is saved to by a wide margin the improve production yields of circuit board of rapid liter and the rapid drawdown of having avoided the outer surface temperature of press mold wheel, adopts that the thermal conductivity of copper tube replacement of irritating oil is direct irritates oily in the through -hole, has promoted the security, the change of being convenient for.
Description
Technical field
The utility model relates to pressing wheel field, more particularly, relates to a kind of pressing wheel and pressed film equipment thereof of embedding attached heat pipe.
Background technology
With the arrival in electronic industry epoch, the equipment producing electronic product and finished parts is flourish.Film laminator is a kind of equipment be hot-pressed onto by specific PCB (printed circuit board (PCB)) dry film on pcb board, film to be pressed dry is erected on film laminator equipment, when pcb board is by film laminator, two pressing wheels arranged up and down, to pressure, rely on the pressure and temperature of pressing wheel to make dry film closely be attached to pcb board surface.
The dry film that press mold process requirements press against on monoblock pcb board surface is neat, even, any bubble and gauffer is not allowed to produce, this just requires that upper and lower pressing wheel is consistent on pressing wheel length direction to the pressure produced during pressure, pressing wheel bondline thickness and hardness suitably, only accomplish some guarantee press mold quality above.
At present, the hot pressing wheel on PCB pressed film equipment, is all place heater from endoporus, conducts heat through ferrous metal.Directly can make that metal heat-conducting differs, temperature height is not whole by the design of metal heat transfer, wheel temperature is subject to surrounding air affects that to cause more greatly gradient of temperature to change fast, thus cause the phenomenons such as the thickness easily forming film on the press mold of plate face differs, film wrinkle, minute bubbles, cause that plate face fraction defective is large, cost of idleness, even degumming phenomenon.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of pressing wheel and pressed film equipment thereof of embedding attached heat pipe, and the fast and temperature stabilization of its uniformity of temperature profile, heat conduction, variations in temperature affects little by surrounding air, gradient of temperature change slowly.
For achieving the above object, the technical scheme that provides of the utility model is as follows:
A pressing wheel for embedding attached heat pipe, described pressing wheel comprises body, is arranged at the thermal source in body and is coated on the glue face outside body;
Be provided with multiple through hole run through in the tube wall of described body, described through hole is uniformly distributed in tube wall, and described each through hole has been embedded in heat pipe;
Described heat pipe is hollow structure, and its inner filling has conduction oil, closed at both ends;
Described each through hole two ends are provided with sealing-plug.
As preferably, described heat pipe is copper pipe.
As preferably, described through hole and heat pipe cylindrical.
As preferably, described through hole has six at least.
A kind of pressed film equipment, described pressed film equipment is provided with above-described pressing wheel.
Compared with prior art, the beneficial effects of the utility model are: 1, variations in temperature is soft, and temperature passes to pressing wheel outer surface again via conduction oil, avoid rising sharply and rapid drawdown of pressing wheel hull-skin temperature; 2, temperature stabilization, variations in temperature affects little by surrounding air, gradient of temperature change is slow; 3, uniformity of temperature profile, can not cause the phenomenon that press mold thickness differs; 4, the phenomenon causing film wrinkling because local temperature is overheated is significantly reduced; 5, significantly minimizing causes minute bubbles phenomenon; 6, can not depart from glue material because hot temperature contrast causes; 7, the setting of seal washer drastically increases safety and stability; 8, significantly improve the yields of producing circuit board, save cost; 9, adopt the heat-conducting copper pipe of filling with oil to replace and directly in through hole, fill with oil, improve security, be convenient to change.
Accompanying drawing explanation
Fig. 1 is the generalized section of pressing wheel described in the utility model;
Fig. 2 is the schematic diagram in the A-A cross section of pressing wheel in Fig. 1.
Reference numeral:
Sealing-plug-5, heat pipe-4, through hole-3, glue face-2, body-1
Detailed description of the invention
Below in conjunction with drawings and Examples, the pressing wheel of a kind of embedding attached heat pipe described in the utility model and pressed film equipment thereof are described further.
Be below a kind of embedding pressing wheel of attached heat pipe described in the utility model and the preferred example of pressed film equipment thereof, therefore do not limit protection domain of the present utility model.
Embodiment 1
Fig. 1 shows a kind of generalized section of pressing wheel of embedding attached heat pipe, and Fig. 2 is the schematic diagram in the A-A cross section of pressing wheel in Fig. 1, and this pressing wheel comprises body 1, is arranged at the thermal source in body 1 and is coated on the glue face 2 outside body 1; Be provided with multiple through hole 3 run through in the tube wall of described body 1, described through hole 3 is uniformly distributed in tube wall, and described each through hole 3 has been embedded in heat pipe 4; Described heat pipe 4 is hollow structure, and its inner filling has conduction oil, closed at both ends; Described each through hole 3 two ends are provided with sealing-plug 5.When thermal source is by tube wall transferring heat, owing to being evenly distributed with heat pipe 4 in tube wall, in heat pipe 4, conduction oil has good heat conductivility, can make heat rapidly and evenly be delivered to glue face 2, the heat conductivility in glue face 2 is poor, effectively can reduce the loss of heat, make variations in temperature slow, body 1 temperature can be prevented too high and damage product simultaneously, the temperature needed for effective control can be stablized, heat pipe 4 in the present embodiment adopts heat conductivility preferably copper pipe equally, makes heat conduction rate faster.
In this enforcement, described through hole 3 is cylindrical with heat pipe 4, and described through hole 3 and heat pipe 4 respectively have 12.
Embodiment 2
A kind of pressed film equipment, described pressed film equipment is provided with the pressing wheel described in embodiment 1.
In sum, the beneficial effects of the utility model are: 1, variations in temperature is soft, and temperature passes to pressing wheel outer surface again via conduction oil, avoid rising sharply and rapid drawdown of pressing wheel hull-skin temperature; 2, temperature stabilization, variations in temperature affects little by surrounding air, gradient of temperature change is slow; 3, uniformity of temperature profile, can not cause the phenomenon that press mold thickness differs; 4, the phenomenon causing film wrinkling because local temperature is overheated is significantly reduced; 5, significantly minimizing causes minute bubbles phenomenon; 6, can not depart from glue material because hot temperature contrast causes; 7, the setting of seal washer drastically increases safety and stability; 8, significantly improve the yields of producing circuit board, save cost; 9, adopt the heat-conducting copper pipe of filling with oil to replace and directly in through hole, fill with oil, improve security, be convenient to change.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
