A kind of dress photovoltaic welding belt parts the power take-up a little
The utility model relates to a kind of solar photovoltaic assembly, particularly a kind of photovoltaic welding belt take-up.
Along with the degree of automation that solar photovoltaic assembly is produced is increasingly high, the demand of axle dress welding is increasing, and the yield strength of welding requires more and more stricter.This to the take-up of welding require increasingly high.
Make a general survey of the production facilities of present axle dress welding, generally adopt the torque motor take-up, adopt line flowing mode winding displacement, treat take-up finish after after-combustion finished product once more.Its weak point is, the regulation disproportional plastic elongation intensity control difficulty of this mode long flow path, welding, and the take-up degree of tightness is inconsistent, and side-bend is bigger.
The utility model content
The purpose of the utility model provides a kind of dress photovoltaic welding belt and parts the power take-up a little, has shortened manufacturing process, and actv. has been controlled takeup tension, has reduced disproportional plasticity and has prolonged intensity, makes the take-up degree of tightness consistent, and side-bend is little.
The purpose of the utility model is achieved in that a kind of dress photovoltaic welding belt parts the power take-up a little, comprises being installed in the frame top guide bar, slidably is provided with motor cabinet on the guide rod; Said motor cabinet links together through screw mandrel and winding displacement motor; Said winding displacement motor is installed on the frame, and coiling electric motor is installed on the motor cabinet, and relative fixed has I-beam wheel on the coiling electric motor output shaft; Photovoltaic welding belt is wound on the I-beam wheel through guide wheel; Be provided with straining pulley between said guide wheel and the I-beam wheel, the end of straining pulley is provided with tension pick-up, also is connected with coder on the said coiling electric motor.
During the utility model work, welding gets into straining pulley through guide wheel, gets into I-beam wheel from straining pulley again, under the drive of coiling electric motor, is wound on the I-beam wheel; Be arranged on that tension pick-up on the straining pulley is sent tension signal into PLC and setting value compares, thereby the rotating speed of control coiling electric motor is realized the control to tension force, winding displacement electric machine control leading screw rotates; Make motor cabinet along the screw mandrel axial action, realize the axle moving winding displacement of welding on I-beam wheel, compared with prior art, the beneficial effect of the utility model is; This device is through the coiling electric motor take-up, and the winding displacement motor shaft moves winding displacement, adopts tension pick-up to monitor tension force on the line in real time, and then realizes the control to tension force; Reduced disproportional plasticity and prolonged intensity, made the take-up degree of tightness consistent, side-bend is little; Simultaneously, shortened manufacturing process, said coder is used to detect the I-beam wheel rotating speed; Impulse singla makes it with respect to coiling electric motor run-in synchronism through servo-control unit control winding displacement motor, makes that the take-up process is more accurate.The utility model can be used in the take-up process of photovoltaic welding belt.
In order further to control tension force well, be provided with reel between said straining pulley and the I-beam wheel.
For the ease of in time fast controlling the rotating speed of winding displacement motor and coiling electric motor, said winding displacement motor is a servomotor, and said coiling electric motor is a permanent magnet DC motor.
As the further improvement of the utility model, said straining pulley is provided with three.Simplified its structure.

The specific embodiment
A kind of dress photovoltaic welding belt shown in Fig. 1-2 parts the power take-up a little, comprises being installed in frame 10 top guide bars 8, slidably is provided with motor cabinet 7 on the guide rod 8; Motor cabinet 7 links together through screw mandrel 5 and winding displacement motor 9, and winding displacement motor 9 is installed on the frame 10, and coiling electric motor 11 is installed on the motor cabinet 7; Relative fixed has I-beam wheel 6 on coiling electric motor 11 output shafts; Photovoltaic welding belt 1 is wound on the I-beam wheel 6 through guide wheel 2, is provided with three straining pulleys 3 between guide wheel 2 and the I-beam wheel 6, is provided with reel 4 between straining pulley 3 and the I-beam wheel 6; The end of straining pulley 3 is provided with tension pick-up 13; Also be connected with coder 12 on the coiling electric motor 11, winding displacement motor 9 is a servomotor, and coiling electric motor 11 is a permanent magnet DC motor.
During the utility model work; Welding 1 gets into I-beam wheel 6 through guide wheel 2, straining pulley 3, reel 4, is being wound under the dynamic action of permanent magnet DC motor on the I-beam wheel 6, simultaneously; Servomotor control I-beam wheel 6 is accomplished coiling and the winding displacement process of welding 1 on I-beam wheel 6 along guide rod 8 axial motions; Be arranged on that tension pick-up 13 on the straining pulley 3 is sent tension signal into PLC and setting value compares, thereby the rotating speed of control permanent magnet DC motor is realized the control to tension force; Thereby reduced disproportional plasticity and prolonged intensity, made the take-up degree of tightness consistent, side-bend is little; Coder 12 is used to detect I-beam wheel 6 rotating speeds; Impulse singla makes it with respect to permanent magnet DC motor run-in synchronism through servo-control unit control servomotor, makes that the take-up process is more accurate.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
