A kind of automatic film tearing equipmentTechnical field
The invention belongs to field of mechanical technique, is used to remove Mobile phone screen, display, LED diffuser plates more particularly to one kindOr the dyestripping equipment of the electronic product such as LED light guide plates top layer diaphragm.
Background technology
The electronic products such as Mobile phone screen, display, LED diffuser plates or LED light guide plates can be in the final step of production processThe layer protecting film of layer adhesion thereon, the diaphragm can protect product will not be because of touching during storage, transport etc.Hit, rub and produce damage.When product continues downstream process, it is necessary to which the diaphragm of upper layer is removed.
Existing dyestripping method is mostly artificial dyestripping, by manually removing the diaphragm for being adhered to product surface, stillThe labor intensity of artificial dyestripping is larger and less efficient, has a strong impact on the production efficiency in product downstream；And manually dyestripping is easyRotten diaphragm is torn, improves the scrappage of product, so as to improve the production cost of product.
In addition, although some existing Coating-removing machines can save manual labor, dyestripping efficiency is improved, is not in tear rotten protectionThe phenomenon of film, but its dyestripping effect is still not so good as people's will：For example, dyestripping method, coat peeling unit and dyestripping equipment(CN102064087A) a kind of method that product surface pad pasting is removed using perching knife is disclosed in, is needed when removing pad pasting using perching knifeAccuracy that will be higher, if control is bad perching knife can be caused directly to be contacted with product surface, so as to cause the breakage of product；AgainSuch as, dyestripping board is with disclosing a kind of side that product surface pad pasting is removed using grinding abrasive disk in dyestripping method (CN102896876A)Method, the pad pasting in plate edge location is taken up by the rotation of grinding abrasive disk, make between pad pasting and product surface exist one compared withBig gap, then a special fixture is extend into the gap and removes pad pasting.But grinding abrasive disk takes up the mistake of pad pasting in rotationIt may be contacted in journey with product surface, so as to scrape the edge of flower prod, cause product rejection.
Therefore, relevant technical staff in the field have developed a kind of brand-new dyestripping equipment, can not only be completely by productThe diaphragm on surface removes, moreover it is possible to effectively reduces the breakage rate of product, improves the success rate of mechanical dyestripping.
