Through adopting above-mentioned scheme, through being provided with the branch material piece, the fortune material area is buckled the gyration at the discharge end and is formed the peeling part, divides to form out the membrane clearance between material piece and the peeling part, is adsorbed on the fortune material area steadily from the type membrane, when it is along with fortune material area buckle deformation, is destroyed from the vacuum laminating between type membrane and the circuit board, gets into out in the membrane clearance from the type membrane homeopathic, and the circuit board carries out the guided motion to the ejection of compact area by the guide roll that divides material top. In the traditional technical scheme, because the opening is peeled from the end part between the release film and the circuit board, the circuit board is easily attached to the release film again under the action of gravity, so that the subsequent peeling is difficult. In some other technical schemes, in order to solve the problem, after the release film and the circuit board are peeled off manually, the circuit board is manually supported on the feeding belt so as to prevent the circuit board from being attached to the release film again, so that the operation is complex and the efficiency is low. Among this application technical scheme, through adsorbing the hole on the cooperation fortune material area of piece, guarantee from type membrane and the inseparable laminating of fortune material area in the portion of peeling off to make and get into out the membrane clearance from the type membrane homeopathic, the circuit board that peels off then moves to ejection of compact area along with the guide roll, thereby effectually avoided being peeled off the problem of adsorbing once more from type membrane and circuit board after the division, and this automatic dyestripping conveying mechanism degree of automation is high, easy operation and efficiency are higher.
Optionally, the film discharging device further comprises a static eliminating device, wherein the static eliminating device is provided with a gas blowing opening, the static eliminating device is located at the discharging end of the material conveying belt, and the gas blowing opening faces to the inlet of the film discharging gap.
Through adopting above-mentioned scheme, be provided with electrostatic elimination device to make this electrostatic elimination device stabilize the entrance of blowing mouth towards a membrane clearance, so that be close to a membrane clearance from type membrane and circuit board and be, the electrostatic adsorption between the two is destroyed, so that follow-up buckle from the type membrane and get into alone in a membrane clearance. Because adopt electrostatic absorption usually between type membrane and the circuit board, this application technical scheme is through adopting the static remove device to aim at out the entrance in membrane clearance with it, so that the tip of leaving type membrane and circuit board laminating position loses the electrostatic force of laminating each other, thereby has promoted the convenient degree with the two separation.
Optionally, the blowing opening is inclined upwards.
Through adopting above-mentioned scheme, the mouth of blowing inclines upwards for the wind that carries a large amount of positive and negative ions that blows off by electrostatic elimination device inclines upwards to blow to the circuit board and leave the tip of type membrane laminating, by flexible circuit board comparatively frivolous, thereby it receives to be convenient for after the ascending wind-force of slope upwards to the tilt up more and with break away from the type membrane. In other technical schemes, because the pre-stripping effect of the circuit board and the end part of the release film is poor, when the circuit board is close to the film outlet gap, the problem that the circuit board collides with the material distributing part at the inlet of the film outlet gap to be damaged possibly exists. In the technical scheme of the application, the static elimination device blows air carrying a large number of positive and negative ions from the air blowing port and blows the air obliquely upwards to the inlet of the film outlet gap, so that on one hand, static elimination between the circuit board and the release film is convenient for stripping and distributing materials; on the other hand, the ascending wind of slope can be blown the circuit board slightly, and still adsorbs on fortune material area from the type membrane to further played the peeling effect of preferred.
Optionally, the peeling device further comprises a driving motor, wherein an output shaft of the driving motor is connected with the guide roller and used for driving the guide roller to rotate so as to drive the peeled circuit board.
By adopting the scheme, the driving motor drives the guide roller to rotate, so that the stripped circuit board is driven to move; in some technical schemes, the guide roller is usually a driven roller, and only serves as follow-up guide, and needs to be driven by the friction force of the circuit board to the guide roller, so that the effect is poor.

By adopting the scheme, the stripped circuit board is placed on the static transfer piece, so that the problems that the circuit board is directly pulled and abraded by the high-speed moving conveyor belt before being stripped and the circuit board is possibly directly pulled off from the release film are effectively avoided. In the traditional technical scheme, the conveyor belt usually moves at a constant speed, and the moving speed of the discharging belt is high in order to improve the conveying efficiency. Therefore, when the circuit board is long and can not be completely separated from the release film, if the circuit board is contacted with the discharge belt running at a high speed, on one hand, the relative speed between the circuit board and the discharge belt is high, relative slippage can be generated, and the bottom surface element of the circuit board is abraded; on the other hand, the friction force generated by the conveyor belt on the bottom surface of the circuit board can cause the circuit board which is not completely peeled to be pulled by a strong force, and the release film can be driven to be separated from the conveyor belt, thereby seriously affecting the stability of the material separating and peeling process.
