Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing equipment, and more specifically to a photovoltaic module layout device. Background Technology

[0002] Photovoltaic cells are power generation modules that convert solar energy into electrical energy without causing environmental pollution. Therefore, they have been widely researched and applied in situations of energy shortage. The production of photovoltaic cells involves many complex processes. In the photovoltaic module layout process, the main task is to arrange multiple sets of welded single-row solar cells onto a glass plate. Currently, the photovoltaic module layout process relies heavily on manual labor. This process includes cutting and transferring the glass plate, cutting and transferring the EVA monolayer film, arranging the single-row solar cells, and heat-melting the EVA monolayer film, among many other steps. Because each step operates independently, a compact production line cannot be formed, resulting in long processing times and low production efficiency. Furthermore, due to the thin and fragile nature of photovoltaic cells, they are easily damaged during the transfer between processes, leading to significant economic losses. Summary of the Invention

[0007] EVA cutting mechanism is used to cut EVA roll film into EVA single film. The EVA cutting mechanism includes an EVA film fixing component, an EVA film cutting component, and a film taking component disposed below the EVA film cutting component.

[0008] A transfer mechanism is used to transfer the cut EVA single film from the EVA cutting mechanism to a glass plate on the conveyor belt. The transfer mechanism includes a bracket spanning the EVA cutting mechanism and the conveyor mechanism, and an EVA film transfer device is provided on the bracket.

[0028] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] like Figure 1 As shown, a photovoltaic module layout device of the present invention includes a machine base 1, a glass plate loading mechanism 2 disposed at one end of the machine base 1, a conveying mechanism 3 disposed on the machine base 1, a battery string arranging mechanism 4 disposed on one side of the machine base 1 and cooperating with the conveying mechanism 3, an EVA loading mechanism 5 disposed on the other side of the machine base 1, an EVA cutting mechanism 6 disposed near the EVA loading mechanism 5, a transfer mechanism 7 disposed between the conveying mechanism 3 and the EVA cutting mechanism 6, and a hot-melt mechanism 8 disposed on the conveying mechanism 3.

[0030] like Figure 1 As shown, the glass plate feeding mechanism 2 includes a material platform 21 for storing glass plates and a glass plate gripping device 22 disposed above the material platform 21. The glass plate gripping device 22 includes a support frame 221 and a glass plate gripping head 222 disposed on the support frame 221. The glass plate gripping head 222 can move laterally and vertically relative to the support frame 221 to facilitate the glass plate gripping head 222 to grip the glass plate onto the conveying mechanism 3 on the machine base 1.

[0031] like Figure 1 , Figure 2As shown, the conveying mechanism 3 includes two parallel conveyor belts 31. Conveyor belt blocking devices 32 are located between the two conveyor belts 31, below the transfer mechanism 7, below the hot-melting mechanism 8, and near the battery string arrangement mechanism 4. The three blocking devices 32 are spaced equally apart. Each blocking device 32 includes a lifting platform 321 and fixed clamps 322 located at both ends of the lifting platform 321. The fixed clamps 322 can move up and down with the lifting platform 321, and can also move relative to the lifting platform 321. The lowering platform 321 moves horizontally left and right to adjust the distance between the fixed clamp 322 and the lifting platform 321. The blocking device 32 is also equipped with a sensor 323. When the sensor 323 inside the blocking device 32 senses the glass plate passing by on the conveyor belt 31, the lifting platform 321 on the blocking device 32 will rise and lift the glass plate on the conveyor belt 31. The fixed clamps 322 at both ends of the lifting platform 321 will also adjust the distance left and right and abut against the two ends of the glass plate, thereby fixing the glass plate on the lifting platform 321.

[0032] like Figure 1 As shown, the battery string arranging mechanism 4 includes a rotatable and liftable robotic arm 41. The robotic arm 41 picks up the strip-shaped battery strings produced in the previous process and places them onto the arranging equipment, and then arranges the picked-up photovoltaic modules onto the glass plate in sequence.

[0033] like Figure 1 As shown, the EVA feeding mechanism 5 is equipped with an EVA roll film. The EVA feeding mechanism 5 is provided with multiple sets of guide rollers 51. Driven by the motor, the guide rollers 51 unfold the EVA roll film and transport the EVA film to the EVA cutting mechanism 6.

[0034] like Figure 1 , Figure 3 As shown, the EVA cutting mechanism 6 includes an EVA film fixing assembly 61 located near the EVA feeding mechanism 5, an EVA film cutting assembly 62 located behind the EVA film fixing assembly 61, and a film taking assembly 63 located below the EVA film cutting assembly 62. The EVA film fixing assembly 61 includes a liftable fixing clamp 611, the EVA film cutting assembly 62 includes a liftable cutting blade 621, and the film taking assembly 63 includes a laterally movable film taking plate 631. When the EVA film is conveyed to the relevant area of ​​the EVA cutting mechanism 6, the fixing clamp 611 in the EVA film fixing assembly 61 will press down to fix the EVA film, the cutting blade 621 in the EVA film cutting assembly 62 will cut the EVA film into EVA single films of glass size, and finally the film taking plate 631 will transfer the cut EVA single films to the area below the transfer mechanism 7.

[0035] like Figure 1As shown, the transfer mechanism 7 includes a support 71 and an EVA film transfer device 72 mounted on the top of the support 71. The support 71 spans the EVA cutting mechanism 6 and the conveying mechanism 3. The EVA film transfer device 72 can move horizontally and vertically between the EVA cutting mechanism 6 and the conveying mechanism 3. The EVA film transfer device 72 transfers the cut EVA single film to the conveying mechanism 3.

[0036] like Figure 1 , Figure 4 As shown, the hot-melting mechanism 8 is located after the battery string arrangement mechanism 4. The hot-melting mechanism 8 includes multiple sets of hot-melting heads 81 arranged in parallel. The hot-melting heads 81 can be lifted, lowered and translated relative to the conveyor belt 31 on the hot-melting mechanism 8. The hot-melting mechanism 8 can melt the EVA monolayer film placed between the glass plate and the photovoltaic module, thereby playing the role of bonding the glass plate and the photovoltaic module.

[0037] like Figures 1-4 As shown, in the photovoltaic module layout equipment of the present invention, when the glass plate loading mechanism 2 is working, it first grabs the glass plate onto the conveyor belt 31 on the conveying mechanism 3. When the glass plate moves to the corresponding area below the transfer mechanism 7, the lifting platform 321 on the blocking device 32 rises and lifts the glass plate. The fixing clamp 322 then fixes both ends of the glass plate. Then, the transfer mechanism 7 places the cut EVA monolayer film onto the glass plate. Immediately afterwards, the lifting platform 321 descends and drops the glass plate with the EVA monolayer film onto the conveyor belt 31. The glass plate with the EVA monolayer film continues to move forward on the conveyor belt 31. When it moves to the battery string arrangement mechanism 4, the glass plate continues to move forward. When the glass plate containing the EVA monolayer is in the corresponding area, the lifting platform 321 on the blocking device 32 lifts the glass plate containing the EVA monolayer film. The battery string arrangement mechanism 4 places the photovoltaic module on the EVA monolayer film. The lifting platform 321 descends and drops the glass plate onto the conveyor belt 31. The glass plate containing the photovoltaic module continues to move to the corresponding area below the hot-melting mechanism 8. The lifting platform 321 on the blocking device 32 lifts the glass plate again and fixes it. The hot-melting head 81 on the hot-melting mechanism 8 melts the EVA monolayer film between the photovoltaic module and the glass plate and fixes the two together. The lifting platform 321 descends and drops the glass plate onto the conveyor belt 31 and transports it to the next process.

[0038] The present invention discloses a photovoltaic module layout device, wherein a glass plate loading mechanism 2, an EVA cutting mechanism 6, a cell string arrangement mechanism 4, and a hot-melting mechanism 8 are connected in series via a conveying mechanism 3. This enables the coordinated operation of multiple processes, such as glass plate transfer, EVA monolayer cutting and transfer, single-row cell arrangement, and EVA monolayer hot-melting, to form a compact production line. This achieves fully automated production of the photovoltaic module layout process, effectively reducing the layout process time and improving production efficiency. Furthermore, the photovoltaic module layout device of the present invention uses a robotic arm 41 throughout the process of picking up and placing photovoltaic modules, avoiding damage to the cells caused by manual handling of photovoltaic modules.
