Description

Technical Field

[0001] The invention relates to the field of photovoltaic component processing, in particular to a photovoltaic component laminating machine glass plate stacking protection and material taking device. Background Art

[0002] Solar laminators, often called laminators, are used in solar cell photovoltaic production lines. They usually press glass, EVA, cells, EVA and backplane together to form photovoltaic modules. The principle of solar laminators is to apply a certain pressure on the surface of each layer of material and press these materials tightly together under heating. Since photovoltaic modules have a certain thickness, in order to ensure that the lamination is not misaligned during lamination, a lamination frame is usually configured, that is, glass, EVA, cells, EVA and backplane are placed in the lamination frame for lamination.

[0003] In the production process, glass plates are stacked for pre-storage, and then the material is taken directly from the top of the stacked glass plates. In the actual production process, since the air between the smooth glass plates is excluded, the atmospheric pressure easily presses the two glass plates together. Since the smooth glass plates are easily adsorbed to each other, it is easy to grab multiple glass plates at a time when grabbing a single glass plate. Therefore, when storing glass plates, adjacent glass plates are generally stacked in an interlaced manner to reduce the contact area between adjacent glass plates, so as to facilitate the single glass plate to be taken out at a time.

[0004] However, during the storage process, dust and bacteria are easily accumulated on the non-contact positions between the glass plates. The existing technology can only use a dust-free workshop to reduce dust or bacteria. However, during the production process of photovoltaic modules, for example, the edge trimming operation of the back panel will generate dust, and there is a lack of protection measures for the glass plate stack itself, which reduces the yield rate of photovoltaic modules.

[0005] Therefore, it is necessary for us to improve such a method to overcome the above defects. Summary of the invention

[0075] When the present invention works, Fig.11 As shown, when storing the glass plates 900, a whole protective film 300 is used to cover multiple glass plates 900, that is, two layers of protective films 300 are separated between adjacent glass plates 900, and the protective film 300 on the right side of the glass plate 900 is bent and then covered on the protective film 300, and the protective film 300 on the left side of the glass plate 900 will go around the end of the glass plate 900 and then cover another glass plate 900, so that when the protective film 300 is rolled up at the left end, all the protective films 300 can be rolled up. The glass plate 900 is completely rolled up without being overturned; the advantage of this type of glass plate storage is that each glass plate can be protected, and when the previous glass plate is taken away, at least one layer of protective film 300 will also exist on the surface of the next glass plate; it is ensured that each glass plate can be protected when not being grabbed, and the time the glass plate is exposed to the air is reduced. Since it is most important to ensure that the upper and lower surfaces of the glass plate are dust-free for photovoltaic module processing, in this article, the glass plate exposed to the air refers to the upper and lower end surfaces of the glass plate being exposed to the air;

[0076] When grabbing a single glass plate, the following steps are included:

[0077] S1, placing a plurality of stacked glass plates 900 covered with a protective film 300 on a material platform 100, fixing the upper end of the protective film 300 on a film winding roller 220,

[0078] S2, the film winding device 240 of the film winding device 200 is actuated to drive the film winding roller 220 to rotate, and the film winding roller 220 rotates to roll up the protective film 300 from the stacked glass plates 900, at which time the protective film 300 on the top of the top glass plate 900 is torn off, and the top of the top glass plate 900 is exposed; the film winding device 200 stops operating;

[0079] S3, the glass plate grabbing device 400 is actuated, the horizontal moving power device 440 drives the first ball screw mechanism 430 to move the grabbing mechanism 450 to the left end, at which time the grabbing mechanism 450 is located on the top of the uppermost glass plate, and then the second ball screw mechanism of the lifting mechanism 451 is actuated to drive the grabbing suction cup bracket 452 to move downward, at which time the grabbing vacuum suction cup 453 contacts the uppermost glass plate, and the grabbing vacuum suction cup 453 is actuated to absorb the glass plate;

[0080] S4, the second ball screw mechanism of the two sets of lifting mechanisms 451 at the left end is actuated to drive the left end of the glass plate to move upward, while the two sets of lifting mechanisms 451 at the right end are stopped; at this time, the left end of the glass plate is tilted; then the winding power device 240 of the film winding device 200 is actuated to drive the film winding roller 220 to rotate, and a layer of protective film 300 under the top glass plate is torn off from the bottom of the glass plate; Fig.12 As shown, at this time, there is an angle between the protective film 300 and the glass plate, and the glass plate is most easily torn off;

[0081] If the glass plate is lifted up vertically, the protective film below the glass plate will be lifted up by the top glass plate, so that the protective film on the next glass plate will be torn off and even cause the next glass plate to move.

[0082] At this time, since the two sets of lifting mechanisms 451 located at the right end stop, Fig.12 As shown, the right end of the glass plate will be pressed on the protective film on the top of the right end of the next glass plate. At this time, the protective film above the next glass plate will not be torn off, and the next glass plate can be fully protected.

[0083] S5, such as Fig.13As shown, when the protective film 300 below the top glass plate is mostly separated; at this time, only the rightmost end of the top glass plate is in contact with the protective film 300 below, the second ball screw mechanism of the two sets of lifting mechanisms 451 at the right end is actuated to completely separate the top glass plate from the protective film 300 below; the right end of the glass plate rises so that the glass plate is in a horizontal state;

[0084] S6, the horizontal moving power device 440 drives the first ball screw mechanism 430 to move to the rightmost end, at which time the glass plate is located at the top of the receiving plate 503; the second ball screw mechanism of the lifting mechanism 451 is actuated to drive the glass plate to move downward onto the receiving plate 503, and the vacuum suction cup 453 is actuated to put down the glass plate;

[0085] Then repeat the cycle S2-S7 to achieve the grabbing of the next glass plate;

[0086] Meanwhile, in the illustration of the present invention, in order to more clearly show the structure between the protective film and the glass plate, the ratio of the thickness between the protective film and the glass plate is adjusted, and the thickness of the film is increased in the illustration; there is no restriction on the thickness of the protective film in the actual production process, but considering the cost issue, the thickness of the protective film is generally between 0.03 mm and 0.06 mm;
