A kind of sensing controls cutting means
Technical field
The present invention relates to photovoltaic product, be specifically related to the sensing in a kind of photovoltaic welding belt tin equipment and control cutting means.
Background technology
Solar energy belongs to the energy of green clean environment firendly, and the photovoltaic industry based on solar energy is fast development at home and abroad in recent years.The use of required tin plating welding need to be cut according to required length by solar photovoltaic industry through guillotine, for making guillotine have the effect of semi-automation, guillotine is typically provided induction controller.Traditional guillotine induction installation has the disadvantage that: 1, induction installation sensitivity is not high, and when welding contacts with induction point, induction installation can not make corresponding instruction in time, and employee is often performed manually by the operation controlling guillotine and stopping;2, induction installation is affected relatively larger by extraneous factor.
Summary of the invention
It is an object of the invention to provide a kind of highly sensitive, by extraneous factor affect relatively low, to make to cut degree of accuracy high and be that machine has the sensing of the effect of automatization and controls cutting means.
The technical scheme is that, a kind of sensing controls cutting means, for photovoltaic welding belt tin equipment, including guillotine and induction controller, described induction controller includes sensing and transmits line, induction point, relay, the fixing bar of upper induction point and lower induction point placement plate, it is identical with described welding position that described sensing transmits line position, the fixing bar of described induction point and upper induction point and lower induction point place plate with the use of, described guillotine, induction point and relay power connection.
In a preferred embodiment of the present invention, it is small resistor rate metal wire that described sensing transmits line.
In a preferred embodiment of the present invention, described induction point includes induction point and lower induction point.
In a preferred embodiment of the present invention, described upper induction point is metal wire body U-shape structure, and during the motion of described upper induction point, the fixing bar of above induction point is that axle center rotates.
In a preferred embodiment of the present invention, described lower induction point is disc shape metal plate, and described lower induction point is positioned over lower induction point and places on plate.
Of the present invention is that a kind of sensing controls cutting means, the present invention can make machine operation reach automatization's state, highly sensitive, by extraneous factor affect relatively low, improve cut degree of accuracy, greatly reduce the frequent control that guillotine is switched by staff, improve production efficiency and the quality of product.

Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
Of the present invention is that a kind of sensing controls cutting means, shown in Figure 1, for photovoltaic welding belt tin equipment, including guillotine 1 and induction controller 2, described induction controller 2 includes sensing and transmits line 3, induction point, relay 5, the fixing bar 6 of upper induction point and lower induction point placement plate 7, it is identical with described welding position that described sensing transmits line 3 position, the fixing bar 6 of described induction point and upper induction point and lower induction point place plate 7 with the use of, described guillotine 1, induction point and relay 5 energising connect.
It is small resistor rate metal wire that described sensing transmits line 3.
Described induction point includes induction point 41 and lower induction point 42, described upper induction point 41 is metal wire body U-shape structure, and the fixing bar 6 of above induction point rotates for axle center when described upper induction point 41 moves, described lower induction point 42 is disc shape metal plate, and described lower induction point 42 is positioned over lower induction point and places on plate 7.
In use, under welding contact during induction point, Control is passed through, guillotine is that path is started working, and owing to guillotine and tin machine speed are asynchronous, guillotine duration of work welding ought slowly be strained, after rising certain altitude, the upper induction point of welding contact, by Control, guillotine is open circuit, quit work, ensure to make welding be in free relaxed state all the time, make guillotine guillotine delivery wheel will not produce empty biography because of welding tension, so that impact cuts degree of accuracy.
Lower induction point act as sensing welding minimum point.
Upper induction point act as sensing welding peak.
Of the present invention is that a kind of sensing controls cutting means, the present invention can make machine operation reach automatization's state, highly sensitive, by extraneous factor affect relatively low, improve cut degree of accuracy, greatly reduce the frequent control that guillotine is switched by staff, improve production efficiency and the quality of product.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope that disclosed herein; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
