Description
Technical field
The utility model relates to a kind of device that is used for heating flexible substrate for printed circuit board, refers in particular to a kind ofly directly flexible substrate for printed circuit board to be heated so that stick together the heater of glue drying in the flexible substrate for printed circuit board production process.
Background technology
Flexible printed wiring board (FPC) is widely used in the pivot joint part of mobile phone, digital camera, printer etc., and the chamber of commerce of digital product manufactory buys a large amount of flexible substrate for printed circuit board to flexible substrate for printed circuit board production firm and makes digital product.This flexible substrate for printed circuit board has one deck Copper Foil, the one side of this Copper Foil is sticked together the plastic sheeting that has as insulating barrier, the composition of this plastic sheeting is generally polyimides (Polyimide, hereinafter to be referred as PI), the one side that relevant dealer is sticked together Copper Foil and PI film usually is called the face of sticking together, and another side is called glassy surface.Usually, to stick together glue as the intermediate layer, it is binded mutually between PI film and the Copper Foil, another kind of optionally scheme is, on the direct coated copper foil of PI glue.Transport flexible substrate for printed circuit board for the ease of flexible substrate for printed circuit board production firm to digital product manufacturer, be beneficial to digital product manufacturer simultaneously and carry out following process, flexible substrate for printed circuit board is made the form of whole volume usually by flexible substrate for printed circuit board production firm, the Copper Foil that is otherwise known as volume.
Flexible substrate for printed circuit board production firm makes the Copper Foil volume by following steps at present: glue is sticked together in the one side coating that will have the Copper Foil of uniform thickness earlier; Then the PI film is entirely fitted in and stick together on the glue, the PI film is by sticking together on bonding of glue and Copper Foil or the direct coated copper foil of PI glue to make flexible substrate for printed circuit board; Again the flexible substrate for printed circuit board of making is wrapped on the core pipe, during winding the glassy surface of Copper Foil inwardly, stick together face outside, thereby form the Copper Foil volume.
Yet, because being bonded with the Copper Foil volume of PI film has tens of centimeters width and Copper Foil circumvolution usually and takes up reality, so the volatilizer that sticks together among the glue near Copper Foil volume both sides edge area is easier to be volatilized by the edge, and Copper Foil volume is not easy volatilization near the volatilizer that sticks together among the glue of middle section, thereby causes near descend unfavorable following process+even influence the problem of product quality of the Copper Foil of middle section and PI film degree of adhesion.
Therefore, in order to address this problem, prior art is to adopt the mode of heating to come the glue that sticks together of Copper Foil volume is carried out drying, because oxidation can take place in Copper Foil under the condition of high temperature, so prior art be will loosen the Copper Foil volume be placed in the baking oven that is full of nitrogen Copper Foil involved in capable hot blast heating, utilize heat exchange pattern to accelerate to stick together in the Copper Foil volume volatilizer volatilization of glue.Yet, the back confirms that the temperature of heating Copper Foil volume need reach the volatilizer that can allow Copper Foil volume middle section stick together glue more than 300 degrees centigrade and volatilize fully after deliberation, but adopt the hot blast mode of heating that the Copper Foil volume is heated to this temperature and keeps the required time of this temperature very long, generally need more than 10 hours, therefore production efficiency is very low, has influenced the producer's economic benefit.Moreover, adopt heat exchange pattern, the operator is difficult to accurately control the Copper Foil volume and evenly heats, the temperature in the common zone that keeps to the side when heating rises very fast and slower near the temperature rising of middle section, because temperature contrast makes close Copper Foil volume both sides reach the Copper Foil degrees of expansion difference near central authorities, if the excessive Copper Foil torsional deformation that very easily causes of temperature contrast can only slowly heat up when therefore carrying out heat drying with prior art, and can't promote production efficiency.
In view of prior art Copper Foil is rolled up the problem that heat drying grows, easily causes the Copper Foil torsional deformation required heat time heating time, therefore be necessary to provide a kind of improved technology to overcome above-mentioned shortcoming.
Summary of the invention
Main purpose of the present utility model is to provide a kind of device that is used for heating flexible substrate for printed circuit board, it can directly heat Copper Foil by electric current, voltage, reaches to make to shorten dramatically heat time heating time, make Copper Foil to be heated evenly the effect that is difficult for torsional deformation in heating process.
For reaching the above object, major technique means of the present utility model are: a kind of device that is used for heating flexible substrate for printed circuit board is provided, it comprises a casing, side in described casing is provided with hermatic door, described box house is provided with and utilizes Copper Foil volume heating power principle to make the Copper Foil volume produce the supply unit of heat, the two poles of the earth of described supply unit are connected with the inside and outside two ends of Copper Foil volume respectively, and described device also is provided with monitoring Copper Foil volume temperature controlling unit.
By technique scheme, the present invention utilizes the even resistance of Copper Foil self, and the promptly rapid and evenly heating in energising back can be volatilized the volatilizer between copper foil layer and the PI thin layer fast fully, rolls up the required time thereby shorten the heating Copper Foil effectively.
Further, described control module comprises and is used to measure the temperature sensing device of Copper Foil volume temperature and is used to regulate the register of Copper Foil volume temperature, described register comprises processor and electronics electric control circuit, is set with control heating-up temperature and the automatically controlled programming mode of heat time heating time in described processor.By above-mentioned steps, can thereby being twisted in, Copper Foil be difficult for the distortion that is distorted in the heating process according to predefined pattern to the evenly heating step by step of Copper Foil volume.
Further, in described casing, be provided with and be used for Copper Foil is rolled up sheathed axle thereon, first end of described axle is rotatably mounted on the sidewall relative with hermatic door in the casing, second end is unsettled to hermatic door opening direction horizontal-extending, and first end of described axle penetrates and outwards protrudes out formation one convex extension part from the sidewall of casing, this convex extension part is connected with a swing mechanism, described swing mechanism comprises a motor and two connecting rods, one end of two connecting rods interconnects, and the other end is connected with described motor and described convex extension part respectively.Thereby turning gear is swung back and forth the Copper Foil volume that loosens is heated evenly, in heating process, is difficult for causing torsional deformation because of Copper Foil degrees of expansion difference by swing mechanism; And make in the middle of turning gear swings back and forth at swing mechanism, can help the volatilizer that the flexible printed wiring board middle section sticks together glue and volatilize fully.
