Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic module EVA film manufacturing and placement device. Background Technology

[0002] EVA material, due to its excellent flexibility, shock absorption, slip resistance, and pressure resistance, is widely used in various fields, such as shoe soles, interior materials, packaging films, gaskets, medical devices, hot melt adhesives, and cable insulation. In the solar photovoltaic industry, EVA is the "heart encapsulation material" of solar panels, and it is also adhered to photovoltaic modules for protection. Currently, strip-shaped EVA adhesive strips are commonly used. However, in certain situations (such as at busbar junction boxes), EVA sheets are required. These sheets are perforated products, and the leads to be protected pass through the perforation, allowing the EVA sheet to protect the perimeter of the leads.

[0003] Currently, there is very little equipment specifically designed for continuous production and loading of EVA film. Most systems employ offline EVA film production, followed by manual loading after production. This results in low efficiency, high labor costs, and increasingly fails to meet user needs. Therefore, developing a continuous EVA film production and loading system is a pressing technical problem that needs to be solved. Utility Model Content

[0037] like Figure 1 As shown, this utility model discloses a photovoltaic module EVA film manufacturing and placement device, which can make EVA film 11 from EVA strip 10 and transfer the EVA film 11 to the busbar junction box position 21 on the photovoltaic module 20.

[0038] Specifically, such as Figures 1 to 7 As shown, the photovoltaic module EVA film fabrication and placement equipment includes a film fabrication component 100, a film transport component 200, and a film placement component 300. The film fabrication component 100 is mainly used to fabricate EVA film 11 from EVA adhesive strips 10. The film fabrication component 100 is located on one side of the photovoltaic module 20 in a first direction, as shown in the diagram. Figure 1 As shown in direction a, the film production assembly 100 includes an EVA film reel 110, a feeding mechanism 120, a punching mechanism 130, a cutting mechanism 140, and a feeding mechanism 150 arranged sequentially along the second direction, as shown in direction a. Figure 1As shown in direction b, optionally, the first direction and the second direction are set perpendicularly. The EVA strip reel 110 is used to rotate and release the EVA strip 10. The feeding mechanism 120 includes a feeding power member 121 and a first clamping member. The first clamping member is used to clamp the EVA strip 10. The output end of the feeding power member 121 is connected to the first clamping member and is used to drive the first clamping member to feed along the second direction, so as to sequentially convey the free end of the EVA strip 10 to the punching mechanism 130, the cutting mechanism 140 and the feeding mechanism 150. The punching mechanism 130 is used to punch holes in the EVA strip 10. The cutting mechanism 140 is used to cut the punched EVA strip 10 to form an EVA sheet 11. The feeding mechanism 150 is used to absorb the EVA sheet 11 and convey the EVA sheet 11 to the sheet transfer assembly 200. The film transport assembly 200 is used to receive multiple EVA films 11 and transport them one by one to the film placement assembly 300. The film transport assembly 200 is located above the photovoltaic module 20.

[0039] The photovoltaic module EVA film manufacturing and placement equipment provided by this utility model can continuously feed, punch, cut, and deliver EVA strips 10 through the film manufacturing component 100. The feeding mechanism 120 can transfer the EVA strips 10 segment by segment to the punching mechanism 130, the cutting mechanism 140, and the delivery mechanism 150 by clamping the free end of the EVA strips 10 and using a combination of linear feeding. This is easy to control and facilitates the cooperation between the various mechanisms. The film transfer component 200 can continuously transfer the EVA film 11, and the film placement component 300 can sequentially place the EVA film 11 into different busbar junction box positions 21. This realizes the automatic and continuous manufacturing and continuous feeding of EVA film 11, improves work efficiency, and reduces labor costs. Furthermore, by placing the film-making assembly 100 on one side of the photovoltaic module 20 in the first direction, and sequentially arranging the EVA strip reel 110, feeding mechanism 120, punching mechanism 130, cutting mechanism 140 and feeding mechanism 150 in the second direction, and placing the film transfer assembly 200 and film placement assembly 300 above the photovoltaic module 20, the equipment not only makes the overall layout of each component reasonable, but also makes the continuity of each process good.

The feeding power unit 121 moves the strip forward a certain distance, delivering the end of the strip to the punching mechanism 130. Third, the punching mechanism 130 starts working to punch holes in the EVA strip 10. Fourth, after punching, the feeding mechanism 120 repeats the action to continue feeding the EVA strip 10. The material is fed forward, and the punching mechanism 130 works again (the subsequent feeding mechanism 120 feeds material once, and the punching mechanism 130 punches a hole once); after the EVA strip 10 reaches the cutting position, the cutting mechanism 140 performs the cutting operation, and the part with the hole after cutting forms an EVA film 11 (one EVA film 11 has one hole); after cutting, the output end of the gripping power unit 152 moves downward, and the feeding suction cup 153 picks up the EVA film 11; in the fifth step, after the EVA film 11 is picked up, the output end of the gripping power unit 152 moves upward, and the feeding power unit 151 is activated to transport the EVA film 11 to the film transfer assembly 200, thus completing the production and feeding of one EVA film 11.

[0067] Placement of EVA film 11: As the film transport assembly 200 operates, the EVA films 11 conveyed to the film transport assembly 200 are sequentially spaced in the first direction and transported to the loading position in sequence. The film placement assembly 300 grips the EVA films 11 with the second gripper and places them at the junction box position 21. This process is repeated three times to achieve loading of three films from one photovoltaic module 20. The operation continues continuously in a cycle until the EVA film reel 110 is used up, at which point the EVA film reel 110 is manually replaced.

[0068] The photovoltaic module EVA film fabrication and placement equipment has the following advantages:

[0069] 1. It can continuously produce film online, which is more efficient and makes film loading and unloading faster and more convenient; 2. Changing the material tray does not affect the production line's cycle time, and the production line can continue production when changing materials; 3. Using a two-coordinate module for placement, the equipment cost is lower than that of robot loading.
