Problems solved by technology

However, the backboard is made of FPF, FPE, full PET and PET. The backboard made of these materials has high toughness. Therefore, it is very difficult to peel off the backboard with the fluid sprayed from the spray gun.
It takes at least half an hour to disassemble the entire photovoltaic module, so the efficiency is very low
Thereby, above-mentioned treatment process needs to be improved

Embodiment 1

[0069] Step S1: the jetting device for jetting the fluid is opposite to the back of the photovoltaic module A, such as Figure 9 As shown in the figure, the flow direction of the liquid-containing fluid sprayed by the spray device forms an inclination angle with the back surface of the photovoltaic module A in a non-vertical state; wherein, the fluid is water or a mixture of water and abrasive, and the abrasive is preferably sand, and the fraction of abrasive and water is used. The ratio is: 1-2:98-99, that is, in 100 parts of fluid, the abrasive contained is 1-2 parts, and the water contained is 98-99. By adding abrasives, the cutting of the photovoltaic modules by the abrasives can improve the dismantling efficiency.

[0070] Step S2: controlling the pressure of the jetting fluid from the jetting device, that is, controlling the pressure of the fluid output from the pump 15, so that the fluid containing the liquid forms an incision O on the back of the photovoltaic module, s...

Embodiment 2

[0083] The difference between the dismantling method of this embodiment and the above-mentioned Embodiment 1 is:

[0084] The incision O is a rectangular incision. The pressure of the fluid acting on the back of the photovoltaic module A was 52 MPa. The distance L is 0.7 meters. The first inclination angle α is 60°, and the second inclination angle β is 120°. The first drive mechanism drives the moving beam 2 to drive the nozzle B to move at a speed of 3.2 m / min along the lateral direction X, and the second drive mechanism 14 drives the support 9 to drive the nozzle B to move along the longitudinal direction Z at a speed of 0.9 m / minute.

[0085] According to the dismantling method of Example 2, the dismantling time of one photovoltaic module A is 13.4 minutes.

Embodiment 3

[0087] The difference between the dismantling method of this embodiment and the above-mentioned Embodiment 1 is:

[0088] The incision O is a rectangular incision. The pressure of the fluid acting on the back of the photovoltaic module A is 50MPa. The distance L is 0.5 meters. The first inclination angle α is 50°, and the second inclination angle β is 130°. The first drive mechanism drives the moving beam 2 to drive the nozzle B to move at a speed of 3.0 m / min along the transverse direction X, and the second drive mechanism 14 drives the support 9 to drive the nozzle B to move along the longitudinal direction Z at a speed of 0.8 m / minute.

[0089] According to the dismantling method of Example 3, the dismantling time of one photovoltaic module A is 14 minutes.

Abstract

The invention discloses a disassembling device for a photovoltaic module. The disassembling device comprises a spraying device disposed on an upper frame. The spraying device includes: a first drivingmechanism used for driving a moving beam to move laterally along the upper frame; a nozzle for spraying a disassembling liquid for the photovoltaic module, wherein the flow direction of the liquid sprayed by the nozzle and the back surface of the photovoltaic module form a tilt angle in a non-vertical state; a support mechanism movably arranged on the moving beam; a second driving mechanism disposed on the moving beam and used for driving the support mechanism to mover longitudinally along the upper frame; a pump having an output end connected to the nozzle; and a controller used for controlling the spraying device and the photovoltaic module to move relatively according to a set path, and controlling the liquid sprayed by the spraying device to form a notch on the back surface of the photovoltaic module in order that the liquid enters the photovoltaic module at an oblique angle along the cut. The liquid with pressure is expanded inside the photovoltaic module and achieves cutting. The disassembling device has the advantage of improving disassembly efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a dismantling device for photovoltaic components. Background technique [0002] The structure of a typical photovoltaic module from the front to the back is composed of: glass, first EVA adhesive layer, silicon wafer, second EVA adhesive layer, backplane, fluorine film (some photovoltaic modules do not have fluorine film), the first EVA adhesive The second layer of EVA glues the silicon wafer and the backplane. The recycled photovoltaic modules are disassembled to obtain objects such as precious metals contained in them, so the disassembly of photovoltaic modules has corresponding value. [0003] CN109092842A discloses a dismantling method for scrapped photovoltaic modules. The method includes steps of dismantling aluminum frame, dismantling junction box, removing fluorine film, removing backplate, separating EVA adhesive layer and backplate, separating The step...
