Terms such as "first," "second," and the like, used in this disclosure are intended to distinguish one element from another, without order or importance. Further, in the following description, when referring to the figures, the same reference numbers in different figures denote the same or similar elements.
As shown in fig. 1, the present disclosure provides a glass substrate packaging apparatus, which includes a film coating mechanism 100, an upper sheet conveying mechanism 310, a lower sheet conveying mechanism 320, and a control mechanism 400 for controlling the movement of the film coating mechanism 100, the upper sheet conveying mechanism 310, and the lower sheet conveying mechanism 320.
The film coating mechanism 100 comprises a film coating roller 110 and a protective film 111 wound on the film coating roller 100, the film coating roller 110 is used for rotating when the glass substrate 200 moves in the tangential direction so as to attach the protective film 111 to the glass substrate 200, the protective film 111 is used for replacing spacing paper or spraying protective materials in the related technology, the problem that the surface of the glass substrate 200 is polluted by paper scraps or residual surfaces of the spraying materials can be well solved, meanwhile, the glass surface can be cleaned secondarily by selecting the protective film 111 with proper viscosity, the reject ratio of products is reduced, and therefore improvement of the process technology is achieved. The upper sheet conveying mechanism 310 is used for conveying the glass substrate 200 to be coated to the coating mechanism 100. The lower sheet conveying mechanism 320 is used to convey the coated glass substrate 200 forward (i.e., downstream) from the coating mechanism 100. The control mechanism 400 can control the linear velocity of the film coating roller 110 to be the same as the conveying speed of the glass substrate 200, that is, the outer circle linear velocity of the film coating roller 110 is matched with the speed when the upper sheet conveying mechanism 310 conveys the glass substrate 200 to the film coating roller 110 for film coating, the stable film coating process is ensured, and the glass substrate 200 is prevented from being scratched due to sliding friction between the protective film 111 and the glass substrate 200.
Accordingly, the present disclosure also provides a glass substrate packaging method, referring to fig. 4 in combination with fig. 1, the method comprising: step S101, controlling the upper piece conveying mechanism 310 to convey the glass substrate 200 to be coated to the coating mechanism; step S102, controlling a film coating roller 110 to coat a protective film 111 on the glass substrate 200; in step S103, the lower sheet conveying mechanism 320 is controlled to convey the coated glass substrate 200 forward, and in the process, the linear speed of the coating roller 110 is controlled to be the same as the speed of the upper sheet conveying mechanism 310 and the lower sheet conveying mechanism 320 for conveying the glass substrate 200. It should be noted that the steps S101, S102 and S103 are only used for distinguishing the work content of the components in different areas in the packaging device, and do not have a chronological order, and the three steps can be performed simultaneously in actual production.
Further, the packaging apparatus may further include a cover 900 capable of forming a closed space, and the film covering mechanism 100, the upper sheet conveying mechanism 310, and the lower sheet conveying mechanism 320 are respectively disposed inside the cover 900. This cover body 900 can hold tectorial membrane mechanism 100, last piece transport mechanism 310 and lower piece transport mechanism 320 in the inside of enclosure space, make glass substrate 200 fully keep apart with the external world in tectorial membrane transmission process, can reduce the ageing speed of each inside part of packing plant effectively, the service life is prolonged, reduce glass substrate 200's pollution possibility, and reduce each inside part of packing plant and glass substrate 200 because external factors lead to the probability of damaging, and can obstruct the contact of staff and packing plant inner structure, can reduce the emergence of dangerous accident, ensure staff's safety. Accordingly, in order to enable the glass substrate 200 to be conveyed inside and outside the enclosure 900, both ends of the enclosure 900 in the conveying direction of the glass substrate 200 are formed with an input opening 901 and an output opening 902, respectively.
It should be noted that, in the present disclosure, the upper sheet conveying mechanism 310 and the lower sheet conveying mechanism 320 may respectively extend out of corresponding openings to convey the glass substrates 200 inside and outside the enclosure 900. Alternatively, another conveying structure may be provided outside the opening of the enclosure 900, for example, a feeding mechanism may be provided outside the enclosure 900, the feeding mechanism conveys the glass substrate 200 to the upper sheet conveying mechanism 310 through the input opening 901, a discharging mechanism may be provided outside the enclosure 900, and the lower sheet conveying mechanism 320 conveys the glass substrate 200 to the discharging mechanism through the output opening 902, and then the subsequent conveying process is performed.
Accordingly, in the glass substrate packaging method provided by the present disclosure, in step S101, the glass substrate 200 enters the enclosure 900 through the input opening 901, in step S103, the lower sheet conveying mechanism 320 guides the glass substrate 200 through the output opening 902, and the coated glass substrate 200 passes out of the interior of the enclosure 900.
Further, the packaging device provided by the present disclosure may further include a dust removing mechanism 500, where the dust removing mechanism 500 is installed inside the cover 900, so as to further prevent foreign particles in the external environment from entering the cover 900, thereby ensuring a cleaner internal environment in the process of laminating the glass substrate 200.
Further, referring to fig. 1, according to some embodiments, the dust removing mechanism 500 includes at least a first dust removing part 410 disposed at the input opening 901 and a second dust removing part 420 disposed at the output opening 902. When the uncoated glass substrate 200 enters the interior of the cover body 900 from the outside through the input opening 901, the uncoated glass substrate 200 is cleaned and dedusted by the first dedusting part 410, so that foreign matters existing on the surface of the uncoated glass substrate 200 are prevented from entering the cover body 900; after the film covering is completed, the film-covered glass substrate 200 is cleaned by dust removal through the second dust removing part 420, and then passes through the cover body 900 through the output opening 902, so that the subsequent package of the glass substrate 200 is cleaned. That is, in the present disclosure, the glass substrate 200 can be continuously dedusted. Here, the dust removal may be performed by a non-contact type or a contact type, which is not limited in the present disclosure, and for example, an electrostatic dust removal method may be used. In the present embodiment, referring to fig. 1, the dust removing mechanism 500 can remove dust simultaneously from the upper and lower surfaces of the glass substrate 200, and the first dust removing unit 510 and the second dust removing unit 520 have the same structure.
In addition, the dust removing mechanism 500 may further include a third dust removing part 530, and the third dust removing part 530 may be installed at an upper portion of the cover 900, and may remove dust from the closed space formed by the cover 900, so as to create a dust-free environment for the packaging device. For example, the third dust removing part 530 may be dedusted by a fan, so that dust accumulation in the cover 900 is effectively avoided, a small amount of dust entering the cover 900 is effectively ensured, and the dedusting effect is improved.
Referring to fig. 1, the laminating device 100 further includes a pressure roller 120, the pressure roller 120 is disposed at an opposite side of the laminating roller 110 with respect to the glass substrate 200, the pressure roller 120 serves as a support so that the laminating roller 100 can smoothly perform a laminating operation, and the pressure roller 120 rolls on the glass substrate 200 during the laminating process. Here, the linear velocity of the pressure roller 120 is the same as the linear velocity of the laminating roller 110, so that stable laminating process is ensured, and the glass substrate 200 is prevented from being scratched due to sliding friction between the pressure roller 120 and the glass substrate 200.
Further, the pressure roller 120 and the laminating roller 110 may be configured to be radially close to or far from each other so that the laminating roller 110 can laminate the glass substrate 200 at a preset pressure. Specifically, for glass substrates 200 of different thicknesses, with different distances between the laminating roller 110 and the pressure roller 120 as needed, this process may be implemented by the control mechanism 400 controlling the radial movement of the pressure roller 120. Accordingly, in the glass substrate packing method provided by the present disclosure, the laminating roller 110 and/or the pressure roller 120 are controlled to be radially close to or away from each other at step S102.
Specifically, the control mechanism 400 may include a database storing information on the thicknesses of the glass substrates 200, each corresponding to a pressure value at the time of laminating and a distance between the corresponding laminating roller 110 and the pressure roller 120. Before the packaging device works, a user can firstly input thickness information of the glass substrate 200, such as 0.3mm, 0.2mm, 0.175mm, 0.15mm and the like, into the control mechanism 400, and according to the thickness information, the control mechanism 400 sends instructions to the film coating mechanism 100, the upper sheet conveying mechanism 310 and the lower sheet conveying mechanism 320 respectively to carry out conveying and film coating at preset speed and pressure, so that the surface of the glass substrate 200 is flat after film coating, bubbles and wrinkles are not visible to naked eyes, and the glass substrate 200 is free of cracks and breakage. The control mechanism 400 may include a PLC (programmable logic controller), among others.
Further, according to some embodiments, the pressure roller 120 may also be wound with the protective film 111 to enable double-sided coating of the glass substrate 200. The pressure roller 120 may be designed to have the same structure as the laminating roller 110, and in this case, the pressure roller 120 can be used as a roller for laminating, that is, both can be used as a support for the other in laminating. The upper sheet conveying mechanism 310 guides the glass substrate 200 to the laminating rollers 110 and the pressure rollers 120 to simultaneously coat the upper and lower surfaces of the glass substrate 220 with films.
Referring to fig. 1, the coating mechanism 100 includes a film-releasing roll 130 around which a protective film 111 is wound, and the coating mechanism 100 is arranged such that the protective film 111 unwound from the film-releasing roll 130 is wound around a coating roll 110, and the coating roll 110 adheres the protective film 111 to a glass substrate 200. In this way, the film placing roller 130 serves as a supplying means of the protective film 111, and the film coating roller 110 only serves to guide and coat the protective film 111 on the film placing roller 130 onto the glass substrate 200 during the film coating process, and the overall outer diameter of the film coating roller 110 itself does not change, so that the uniformity of the film coating on the glass substrate 200 can be ensured.
Further, since the outer diameter of the film releasing roller 130 is gradually decreased as the film is applied, which may cause the protective film 111 to be loosened, referring to fig. 1, at least one first tension roller 140 capable of pressing the protective film 111 in a direction perpendicular to the developing direction of the protective film 111 may be provided between the film releasing roller 130 and the film applying roller 110, so that the protective film 111 is always in a tensioned state, and the problem of wrinkles of the protective film 111 may not occur at the time of film application, thereby ensuring the stability of the film. Further, the first tension roller 140 also has a guiding function, and can guide the protective film 111 from the film placing roller 130 to the laminating roller 110 in a reasonable spatial layout. The film releasing roller 130 can also have a reverse braking function, that is, the film releasing roller 130 can only rotate in one direction, so that the normal operation of the film covering process can be ensured, and for example, the film releasing roller 130 can be braked in the reverse direction by a magnetic powder brake or the like.
In addition, the number of the film releasing rollers 130 can be designed to be at least two, one of the film releasing rollers is matched with the film coating roller 110, when the protective film 111 on one of the film releasing rollers 130 is used up, the other protective film 111 on the standby film releasing roller 130 is guided to the film coating roller 110 again, the film coating is continuously carried out on the glass substrate 200, the time is saved, and the film coating efficiency is effectively improved.
In the present disclosure, the upper sheet conveying mechanism 310 and the lower sheet conveying mechanism 320 may be respectively configured as an air blowing type or an ultrasonic type air floating type conveying mechanism, which avoids direct contact between the glass substrate 200 and the sheet conveying mechanism 310 and the lower sheet conveying mechanism 320, reduces contact contamination and scratches of the outside on the surface of the glass substrate 200, and simultaneously, the air blown by the air floating device also has an auxiliary cleaning effect on the glass substrate 200.
When the air floatation conveying mechanism conveys the glass substrate 200, the air buoyancy acts on the whole plate surface of the glass substrate 200, so that uniform supporting force can be provided for the glass substrate 200, the problem of sagging and flexing of the glass substrate 200 is effectively avoided, and the air floatation conveying mechanism is particularly suitable for the condition that the thickness of the glass substrate 200 is small, for example, the thickness is less than 0.2 mm.
In addition, this disclosed last piece transport mechanism 310 and lower piece transport mechanism 320 can also be provided with and be used for prescribing a limit to the off tracking device of preventing on predetermineeing the route with glass substrate 200 to avoid glass substrate along non-flowing direction's rocking, and then avoid influencing the tectorial membrane effect. The deviation preventing device may be, for example, a cylinder or an electric push rod extending perpendicular to the flow direction of the glass substrate 200.
Referring to fig. 2, the packaging device provided by the present disclosure may further include a waste receiving mechanism 710 and a guide mechanism 600, each controlled by the control mechanism 400. Wherein the scrap receiving mechanism 710 is disposed upstream of the upper sheet transport mechanism 310. The guide mechanism 600 is disposed upstream of the upper sheet conveying mechanism 210, and includes a first guide portion 610 for guiding the non-film-coated glass substrate 200 to the upper sheet conveying mechanism 310 and a second guide portion 620 for guiding the non-film-coated glass substrate 200 into the scrap receiving mechanism 710, wherein the first guide portion 610 and the second guide portion 620 are used alternatively. Specifically, when the packaging apparatus is in normal use, the glass substrate 200 is continuously conveyed forward by the first guide portion 610, and the film coating mechanism 100 continuously performs the film coating operation. When an abnormal condition occurs (for example, the protective film 111 of the film releasing roller 130 is used up, defects such as bubbles are frequently generated during film covering, scratches occur on the glass substrate 200, etc.), the glass substrate 200 is continuously conveyed forward from the upstream process, at this time, the conveyance of the glass substrate 200 to the film covering mechanism 100 needs to be stopped in time, the glass substrate 200 can be guided to the scrap receiving mechanism 710 through the second guiding portion 620, and the situation that the subsequent production is influenced because the glass substrate 200 does not pass through the film covering mechanism 100 is prevented. After the abnormality is eliminated, the first guide part 610 is put into use, and the film coating process is continued. However, it should be noted that, in the event of an abnormal situation, the glass substrate 200 may have already moved toward the film coating mechanism 100 beyond the scrap receiving mechanism 710, and at this time, the glass substrate 200 between the scrap receiving mechanism 710 and the film coating mechanism 100 may be cut off by the cutting mechanism, and then the second guide 620 may smoothly guide the glass substrate 200 to the scrap receiving mechanism 710.
For example, the first guide portion 610 may be any type of conveying member for interacting with the upper sheet conveying mechanism 310, the scrap receptacle mechanism 710 may be configured as a general collecting bin and disposed under the conveying member, the second guide portion 620 may employ a power cylinder, and a moving direction of a piston of the power cylinder is perpendicular to a plane of the glass substrate 200 to change the moving direction thereof by pushing the plate surface of the glass substrate 200, and referring to fig. 2, the power cylinder of the second guide portion 620 may push the glass substrate 200 into the scrap receptacle mechanism 710 when moving downward.
Further, the packaging apparatus further includes a film cutting mechanism 720, and referring to fig. 2, the film cutting mechanism 720 is disposed between the film coating roller 110 and the lower sheet conveying mechanism 320, and the film cutting mechanism 720 may include a cutter movable in a direction perpendicular to the protective film 111. If the glass substrate 200 is broken during the film coating process or the packaging mechanism needs to be replaced, the film cutting mechanism 720 may be used to cut the protective film 111, and the second guiding portion 620 guides the glass substrate 200 into the scrap receiving mechanism 710, and the film coating roller 110 is stopped to terminate the film coating on the surface of the glass substrate, so as to prevent the protective film 111 from entering the subsequent process individually, thereby avoiding the waste of the protective film 111 and the reduction of the packaging efficiency. In addition, the laminating mechanism 100 is provided with the pressure roller 120, and the pressure roller 120 may be stopped and the separation of the laminating roller 110 and the pressure roller 120 may be controlled.
Referring to fig. 3, the packaging apparatus includes a material rolling mechanism 800 that may be disposed at a downstream side of the lower sheet conveying mechanism 320, the material rolling mechanism 800 includes a material rolling roller 810 for rolling the coated glass substrate 200, the coated glass substrate 200 is guided by the lower sheet conveying mechanism 320 to pass out of the cover 900 through the output opening 902, and may be guided to the material rolling mechanism 800 by the third guiding mechanism 630, so that the continuity of coating and packaging the glass substrate 200 is achieved, the packaging production efficiency is effectively improved, and the labor force is reduced.
As shown in fig. 3, the winding mechanism 800 may further include at least one second tensioning roller 820 disposed between the winding roller 810 and the lower sheet conveying mechanism 320 and capable of pressing against the glass substrate 200 in a direction perpendicular to the conveying direction of the glass substrate 200, when the winding roller 810 packages the glass substrate 200, the coated glass substrate 200 is packaged after the winding roller is tensioned by the second tensioning roller 820, and the second tensioning roller 820 provides a sufficient pre-tensioning force to the winding, so as to prevent the winding from loosening and wrinkling, and improve the packaging quality of the coated glass substrate 200.
