Abstract
An electrical heating roll for a circuit board compound machine comprises an upper roll and a lower roll; the upper roll is used for feeding a film; the lower roll is used for feeding a copper foil; the upper roll is provide with a heating device; the electrical heating roll is characterized in that the lower roll is further provided with a heating device for allowing the copper foil to maintain a constant temperature to enable the shrinkage percentage of the copper foil after being cooled to the room temperature to be the same as that of the film after being cooled to the room temperature; the heating device of the upper roll and the heating device of the lower roll are respectively and electrically connected with a PLC further electrically connected with an indoor temperature sensor; the PLC is used for adjusting thermal power of the heating devices of both the upper roll and the lower roll at any time according to the indoor temperature during working and the shrinkage percentage of both the film and the copper foil to enable the film and the copper foil to maintain the proper temperature. The electrical heating roll has the advantage that synchronous shrinkage of the film and the copper foil can be realized after being laminated, so that the quality of a film laminating circuit board is ensured.
Description
Technical field
The utility model relates to a kind of electric heating roller of circuit board compounding machine, and it belongs to board production industry.
Background technology
The effect of circuit board compounding machine is film and Copper Foil pressing, compounding machine comprises top roll and lower roll, and top roll enters film, and lower roll enters Copper Foil, top roll and lower roll push, film and Copper Foil are forced together, and traditional practice is in top roll, to have heater, will after film heating, force together with Copper Foil, the film that temperature is higher and temperature compared with the Copper Foil at the end force together cooling after, contraction that can not be synchronous, film shrinkage factor is high, so the bonding quality of film and Copper Foil often has problem.
Summary of the invention
For overcome film that temperature is higher and temperature compared with the Copper Foil at the end force together cooling after, the shortcoming of contraction that can not be synchronous, the utility model proposes a kind of electric heating roller of circuit board compounding machine.
The electric heating roller of sort circuit plate compounding machine, comprise top roll and lower roll, top roll enters film, lower roll enters Copper Foil, in top roll, there is heater, it is characterized in that, in lower roll, also have heater, heater in lower roll is keeping certain temperature by Copper Foil, and the shrinkage factor while making Copper Foil cool to room temperature and when film cooling arrives room temperature equates.
Heater in top roll and the heater in lower roll are electrically connected to PLC controller respectively, PLC controller is also electrically connected to indoor temperature transmitter, PLC controller is adjusted heater in top roll and the thermal power of the heater in lower roll at any time according to the shrinkage factor of the room temperature in when work and film, Copper Foil, allows film and Copper Foil keep appropriate temperature.
The utility model has the advantages that: synchronous contraction after film and Copper Foil pressing, has guaranteed the quality of overlay film circuit board.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: 1, top roll, 2, lower roll, 3, film, 4, Copper Foil, 5, the heater in top roll, 6, the heater in lower roll, 7, PLC controller is electrically connected to, 8, indoor temperature transmitter.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail as follows:
In Fig. 1, the electric heating roller of sort circuit plate compounding machine, comprise top roll 1 and lower roll 2, top roll 1 enters film 3, lower roll 2 enters Copper Foil 4, has heater 5 in top roll 1, also has heater 6 in lower roll 2, heater 6 in lower roll allows Copper Foil 4 keep certain temperature, and the shrinkage factor while making Copper Foil 4 cool to room temperature and during film 3 cool to room temperature equates.
Claims (2)
1. the electric heating roller of a circuit board compounding machine, comprise top roll and lower roll, top roll enters film, lower roll enters Copper Foil, in top roll, there is heater, it is characterized in that, in lower roll, also have heater, heater in lower roll is keeping certain temperature by Copper Foil, and the shrinkage factor while making Copper Foil cool to room temperature and when film cooling arrives room temperature equates.
2. the electric heating roller of a kind of circuit board compounding machine according to claim 1, is characterized in that, the heater in top roll and the heater in lower roll are electrically connected to PLC controller respectively, and PLC controller is also electrically connected to indoor temperature transmitter.
