[0026] Please also refer to Figure 1 and Figure 2The embodiment provides a kind of photovoltaic module edge cleaning equipment, including main platform 1, mobile device 2 and edge cleaning device 3, as shown in the figure.The main platform 1 is used to place the photovoltaic module P to be cleaned edge, and the power output end of mobile device 2 is fixedly connected with edge cleaning device 3, and mobile device 2 can drive edge cleaning device 3 to move to the position of closely adhering to the side of photovoltaic module P.

[0027] Please refer to Figure 3 Edge cleaning device 3 includes total cutter housing 31 and multiple cutter units, each cutter unit includes motor 32, moving blade 33 and fixed blade cylinder 34.Total cutter housing 31 has installation cavity 30 inside, and multiple cutter units are installed in installation cavity 30, wherein moving blade 33 is located in fixed blade cylinder 34.Please refer to Figure 4 Multiple moving blades 33 are distributed radially with the center of fixed blade cylinder 34.The rotating shaft of motor 32 is fixedly connected with moving blade 33, fixed blade cylinder 34 is fixed in installation cavity 30 of total cutter housing 31, motor 32 can drive moving blade 33 to rotate relative to fixed blade cylinder 34, installation cavity 30 of total cutter housing 31 has opening for encapsulation glue to extend into, and the inner wall of fixed blade cylinder 34 has hole groove (not shown in the figure) for encapsulation glue to extend into.

[0028] The four sides of main platform 1 are each provided with mobile device 2 and edge cleaning device 3.Each mobile device 2 includes lifting mechanism and translation mechanism, the translation mechanism is fixedly connected to the power output end of the lifting mechanism, and the edge cleaning device 3 is fixedly connected to the power output end of the translation mechanism.

[0029] Specifically, the above-mentioned lifting mechanism includes base 21, lifting power source 22, vertical sliding block 23 and vertical guide rail 24.The vertical guide rail 24 is vertically fixed on the base 21, the vertical sliding block 23 is slidingly installed on the vertical guide rail 24, the vertical sliding block 23 is fixedly connected to the power output end of the lifting power source 22, and the translation mechanism is fixedly installed on the vertical sliding block 23.It should be noted that the lifting power source 22 can be a linear drive structure composed of a motor and a screw pair, or a linear extension structure composed of a pneumatic cylinder and a telescopic rod, or a transmission structure composed of a motor, a belt pulley and a belt.The specific structure of the lifting power source 22 is not limited in the embodiment, as long as it can output reciprocating linear motion.The lifting power source 22 can drive the vertical sliding block 23 to slide up and down along the vertical guide rail when working, and the translation mechanism and the edge cleaning device 3 are fixedly connected to the vertical sliding block 23, so the translation mechanism and the edge cleaning device 3 also slide up and down with the vertical sliding block 23, so that the edge cleaning device 3 can better align the side of the photovoltaic module P, or match photovoltaic modules P of different thicknesses.

[0030] Specifically, the translation mechanism includes a translation power source 25 and a translation slider 26 fixedly connected with the power output end of the translation power source 25, and the edge cleaning device 3 is fixedly installed on the translation slider 26. It should be noted that the translation power source 25 can be a linear driving structure composed of a motor and a screw pair, can be a linear extension structure composed of a cylinder and an extension rod, or can be a transmission structure composed of a motor, a belt pulley and a belt, and the specific structure of the translation power source 25 is not limited in the embodiment, as long as it can output reciprocating linear motion. When the translation power source 25 works, it can drive the translation slider 26 to move forward and backward in the horizontal direction. Since the edge cleaning device 3 is fixed on the translation slider 26, the edge cleaning device 3 can move forward and backward together with the translation slider 26, thereby approaching or moving away from the photovoltaic module P.

[0031] Through the above structure design, when the edge cleaning device 3 works, the fast rotation of the moving blade 33 can realize the shearing effect on the high-viscosity encapsulation glue such as polyisobutylene remaining after the lamination of the thin-film photovoltaic module P, thereby cutting the remaining encapsulation glue into debris with a length less than 5 mm. Since the multiple motors 32 drive the moving blade 33 to rotate fast to form a rotating blade array rotating fast, the edge cleaning processing is performed simultaneously, which avoids the pulling and deformation of the encapsulation glue in the internal effective encapsulation area, thereby improving the yield of the edge cleaning processing. Moreover, the multiple cutter units are arranged in a row, which can clean the entire side surface of the thin-film photovoltaic module P at the same time, and a piece of area can be completed in about ten seconds, so the edge cleaning efficiency is high. On the other hand, the rotating moving blade 33 is spaced from the edge of the photovoltaic module P by the fixed blade cylinder 34, which avoids the direct contact of the cutting tool with the edge of the photovoltaic module P, thereby reducing the wear of the cutting tool, prolonging the service life of the cutting tool and reducing the equipment maintenance cost.

[0032] Further, referring again to Figure 1 The photovoltaic module edge cleaning equipment of the embodiment further includes a fixing device 4, a conveying belt 5, a glue debris collecting pipeline 6, a negative pressure generating device a, a glue material pool 7, a transmission mechanism 8, a quality control device 9 and a heating device b.

The negative pressure generating device a is in communication with the inside of the rubber chip collecting pipeline 6, and is used to generate negative pressure to suck the rubber chips in the rubber chip collecting pipeline 6 into the rubber material pool 7. Preferably, the negative pressure generating device a is composed of a motor and a fan blade. The motor drives the fan blade to rotate to generate negative pressure in the rubber chip collecting pipeline 6, so that the cut rubber chips can be transported to the rubber material pool 7 through the pipeline.

[0035] The hole groove in the inner wall of the fixed blade cylinder 34 is about 2mm wide, and one or more hole grooves can be arranged. When multiple hole grooves are arranged, the multiple hole grooves are distributed along the circumferential direction of the inner wall of the fixed blade cylinder 34, and the hole grooves penetrate the fixed blade cylinder 34 along the axial direction of the fixed blade cylinder 34, so that the rubber chips can enter the rubber chip collecting pipeline 6 from the rear end of the hole groove.

[0036] The quality control device 9 is installed on the transmission mechanism 8. When the rubber chips entering the quality control device 9 reach a preset quality, the output valve of the quality control device 9 is opened, the transmission mechanism 8 outputs the rubber chips, and fills the electrode lead-out hole of the photovoltaic module P. The heating device b can extend into the electrode lead-out hole to heat and melt the rubber chips to fill the electrode lead-out hole. Preferably, the heating end of the heating device b is cylindrical, the size and shape are consistent with the filling hole, the surface contains a non-stick coating, and the heating temperature is 100-200℃. The heating and melting of the filled rubber chips can prevent the molten rubber chips from adhering to the heating end.

[0037] It can be seen that the edge cleaning equipment for the photovoltaic module of the embodiment realizes the secondary utilization of the excess rubber by arranging the above-mentioned rubber chip collecting pipeline 6 and the heating device b, and saves the material cost.
