Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic cell assembly production equipment, in particular to an automatic film pasting and feeding device for a reflective film in a gap of a photovoltaic cell assembly. [Background technology]

[0002] A photovoltaic module includes a back panel, a glass plate covering the back panel, and a number of battery modules located therebetween. There will be gaps between the battery modules. In order to make full use of the gaps between the battery modules, a reflective film can be pasted at the gaps between the battery modules. The reflective film can be used to reflect the light energy irradiated at the gaps between the battery modules onto the glass plate, and then reflected to the battery modules through the glass plate, so as to make full use of the light energy at the gaps between the battery modules and improve the utilization rate of light energy.

[0003] There are film-sticking equipment designed for sticking reflective films at the gaps of photovoltaic cell modules. For example, patent publication number CN 216980595 U discloses a gap film-sticking device for solar modules, which includes a complete machine chassis, a transportation line arranged in the complete machine chassis, a series film-sticking assembly and a sheet film-sticking assembly correspondingly arranged above the transportation line, and the series film-sticking assembly, the sheet film-sticking assembly and the transportation line move relative to each other; the transportation line includes a feeding mechanism, a first transportation section connected to one side of the feeding mechanism in the discharge direction, a second transportation section connected to one side of the first transportation section in the discharge direction, and a discharging mechanism connected to one side of the second transportation section in the discharge direction. The products to be film-sticked are manually loaded from the feeding mechanism, and pass through a series film-sticking machine position, at least one sheet film-sticking machine position, and a discharging mechanism in sequence. During the film-sticking process, the products to be film-sticked are transported by the transportation line, and a conveyor belt or a double-speed chain is used to drive the products to be film-sticked forward. The conveyor belt and the double-speed chain also have a lifting effect. When the conveyor belt and the double-speed chain are lowered, the products to be film-sticked can be film-sticked at the expected position.

[0004] Although the above solution can apply film at the gaps between photovoltaic cell modules, there are still the following problems: the feeding module of the film-applying machine is set above the transportation direction of the conveyor line, and needs to be moved manually to the top of the conveyor line for material replacement, which is difficult and time-consuming to operate.

The ends of the plurality of reflective films 900 are uniformly restricted on the limit baffle. The third driving member 462 drives the first pressing head 463 to press the reflective film 900. The first driving member 41 drives the first supporting plate 42 to rise and drives the reflective film 900 in the first carrier 461 to rise together. After rising to the right position, the second driving member 43 drives the second supporting plate 44 to move left or right to transport the reflective film 900 to the hot melt bonding mechanism 5 for automatic material connection.

[0036] The hot melt bonding mechanism 5 includes a fourth driving member 51, an upper clamping plate 52 and a lower clamping plate 53 fixed to the output end of the fourth driving member 51 and driven by the fourth driving member 51 to open and clamp, a heat-welding carrier 54 fixed to the lower clamping plate 53 and used to heat and weld the reflective film 900, and an upper pressing head 55 arranged on the upper clamping plate 52 and used to press the reflective film 900 on the heat-welding carrier 54, a plurality of bearing blocks 541 for bearing the reflective film 900 are arranged on the upper surface of the heat-welding carrier 54, and a plurality of bearing blocks 541 corresponding to the bearing blocks 541 and used to press the bearing blocks 540 are arranged on the upper pressing head 55. The external heat source heats the heat-welding carrier 54 to heat the supporting block 541, and the first material head pressing and conveying mechanism 3 or the second material head pressing and conveying mechanism 4 conveys the reflective film 900 on the new material roll to the top of the supporting block 541. The material tail pressing and conveying mechanism 7 conveys the reflective film 900 on the almost used material roll to the top of the supporting block 541. The fourth driving member 51 drives the upper clamping plate 52 and the lower clamping plate 53 to clamp so that the pressing block 551 of the upper pressure head 55 and the supporting block 541 of the heat-welding carrier 54 are pressed tightly, thereby realizing automatic heat welding.

[0037] The tail material pressing and conveying mechanism 7 comprises a third support plate 71, a fifth driving member 72 fixed on the third support plate 71, a moving block 73 driven by the fifth driving member 72 to move left and right in the avoidance hole on the third support plate 71, a second pressing assembly 74 fixed on the moving block 73 and pressing the remaining reflective film 900 on the almost used-up material roll, and a second carrier 75 fixed at the end of the third support plate 71 near the tail material cutting mechanism 6 and carrying the reflective film 900. The second pressing assembly 74 comprises a third carrier 741, a sixth driving member 742 arranged above the third carrier 741, a fourth support plate 743 driven by the sixth driving member 742 to move up and down, and a plurality of second pressing heads 744 arranged on the fourth support plate 743 and extending into the third carrier 741 to press the reflective film 900.

When the reflective film 900 on the first feeding mechanism 1 or the second feeding mechanism 2 is almost used up, the sixth driving member 742 drives a plurality of second pressing heads 744 to press 900, the seventh driving member 61 drives the pressing plate 63 and the cutting knife 64 to descend at the same time, the pressing plate 63 presses the reflective film 900 in the second carrier 75, and the cutting knife 64 neatly cuts the reflective film 900 pressed by the pressing plate 63, and the fifth driving member 72 drives the moving block 73 to drive the second pressing assembly 74 to move left or right, thereby conveying the neatly cut reflective film 800 to the heat-sealing carrier 54 for automatic material connection.

[0039] The feeding principle of the automatic film feeding device 100 is as follows: if the reflective film 900 on the second feeding mechanism 2 below is almost used up, the second pressing component 74 of the tail pressing conveying mechanism 7 presses the reflective film 900, and the tail cutting mechanism 6 neatly cuts the reflective film 900, and the tail pressing conveying mechanism 7 conveys the reflective film 900 to the heat-welding carrier 54 of the hot-melt bonding mechanism 5, and the second driving member 43 of the second material head pressing conveying mechanism 4 drives the second supporting plate 44 to drive the second pressing component 446 away from the hot-melt bonding mechanism 5, and the first driving member 41 drives the first supporting plate 42 to move downward into place, and at the same time, the reflective film 900 on the first feeding mechanism 1 above is passed through the first material head. The first head pressing and conveying mechanism 3 makes the ends of several reflective films 900 uniformly restricted on the limit baffle. After the first pressing assembly 46 of the first material head pressing and conveying mechanism 3 presses the reflective film 900, the first driving member 41 drives the first supporting plate 42 to descend to its position, the second driving member 43 drives the second supporting plate 44 to drive the second pressing assembly 446 to convey the reflective film 900 to the heat-welding carrier 54, and the fourth driving member 51 drives the upper clamping plate 52 and the lower clamping plate 53 to clamp so that the pressing block 551 of the upper pressing head 55 and the bearing block 541 of the heat-welding carrier 54 are pressed, and the material is automatically heat-welded to realize automatic feeding. After the automatic material connection is completed, the first feeding mechanism 1 above feeds the material. If the reflective film 900 on the first feeding mechanism 1 above is almost used up, according to the corresponding process, the first material head pressing and conveying mechanism 3 rises, and the second material head pressing and conveying mechanism 4 rises and heat-welds with the hot-melt bonding mechanism 5 to realize the feeding of the second feeding mechanism 2 below.

The first feeding mechanism 1 at the top and the second feeding mechanism 2 at the bottom feed alternately. The feeding mechanisms arranged above and below are equivalent to being provided with a material preparation area, which can leave enough time for material replacement, has high production efficiency, and the material replacement operation is simple. Simple; (3) A hot melt bonding mechanism 5 is provided between the upper first feeding mechanism 1 and the lower second feeding mechanism 2. The hot melt bonding mechanism 5 can heat-bond several reflective films 900 at the same time. When the reflective film 900 on one of the feeding mechanisms is almost used up, the remaining reflective film 900 on the feeding mechanism can be automatically heat-bonded with the reflective film 900 on the new material roll on the other feeding mechanism to continue the film laminating process.
