According to the disassembling device, the invention provides a disassembling method of a photovoltaic module, which is specifically described by the following embodiments:
example 1
Step S1: the spraying device for spraying the fluid is opposite to the back surface of the photovoltaic module a, and as shown in fig. 9, the flow direction of the fluid containing the liquid sprayed by the spraying device forms an inclination angle with the back surface of the photovoltaic module a in a non-perpendicular state; wherein the fluid is water or a mixture of water and abrasive, the abrasive preferably adopts sand, and the part ratio of the abrasive to the water is as follows: 1-2:98-99, i.e. 100 parts of fluid, contains 1-2 parts of abrasive and 98-99 parts of water. Through adding the abrasive material, the abrasive material can promote the efficiency of disassembling to the cutting that photovoltaic module formed.
Step S2: the pressure of the fluid injected by the injection device, that is, the pressure of the fluid output by the pump 15 is controlled, so that the fluid containing the liquid forms a notch O on the back of the photovoltaic module, as shown in fig. 2 and 9, the fluid is injected into the photovoltaic module along the notch O at an inclined angle, the fluid with pressure expands and forms a cut in the photovoltaic module, the first EVA adhesive layer is crushed and separated from the glass, the silicon wafer is crushed, the second EVA adhesive layer is separated from the silicon wafer, and more than 95% of the second EVA adhesive layer is bonded with the back plate and is broken into blocks with different sizes. In this example, the pressure of the fluid acting on the back surface of the photovoltaic module a was 60MPa.
Step S3: and controlling the spraying device and the photovoltaic module A to form relative movement according to the set path, and disassembling the whole photovoltaic module by the spraying device according to the mode. As shown in fig. 8 and 9, in this embodiment, the photovoltaic module a is preferably fixed, and the spraying device moves relative to the photovoltaic module a, so that the photovoltaic module a and the spraying device move relatively, that is, the photovoltaic module a is clamped by the limiting block 20 and the movable clamping assembly 21, and cannot move in the disassembling process.
In this embodiment, the lateral direction of the photovoltaic module a is parallel to the lateral direction of the upper frame 1, and the longitudinal direction of the photovoltaic module a is parallel to the longitudinal direction of the upper frame 1.
In the above step S1, the controller 16 controls the third driving mechanism 23 to adjust the distance L between the nozzle B and the photovoltaic module a, which is the distance that the fluid reaches the photovoltaic module a along the inclination angle from the outlet of the nozzle B, that is, the diagonal dimension, instead of the vertical distance between the outlet of the nozzle B and the photovoltaic module. In this embodiment, the distance L is 0.9 meters.
In the above step S3, as shown in fig. 8 and 9, the path includes a first path R1 having a rectangular wave shape, and the spraying device moves along the first path R1 relative to the photovoltaic module to disassemble the photovoltaic module. The first path R1 is set to be rectangular wave, the second driving mechanism 14 drives the support 9 to drive the spray head B to move along the positive half-axis direction of the longitudinal direction Z of the upper frame 1, after the positive half-axis along the longitudinal direction Z runs through the set travel, the movable beam 2 is driven by the first driving mechanism to move along the transverse direction of the upper frame 1, and then the second driving mechanism 14 drives the support 9 to drive the spray head B to move along the negative half-axis direction of the longitudinal direction Z of the upper frame 1. Therefore, the advantage point of setting the first path R1 to be rectangular wave is that the spray nozzle B is always in a translational state in the working process of the spraying device, so that the direction of the spray nozzle B does not need to be adjusted when the spray nozzle B moves along the positive half shaft and the negative half shaft of the longitudinal Z, and the disassembly efficiency is improved.
In the above steps S1 and S3, on the basis of not adjusting the direction of the shower head B, as shown in fig. 9, the inclination angle includes a first inclination angle α and a second inclination angle β, and when the spraying device moves along the first path R1 toward the positive half axis direction of the longitudinal direction Z of the photovoltaic module a, the inclination angle formed by the flow direction of the fluid and the back surface of the photovoltaic module a is the first inclination angle α, and the first inclination angle α is an acute angle along which the fluid is injected into the photovoltaic module a. The first inclination angle α is preferably 45 °.
In the above steps S1 and S3, as shown in fig. 9, when the spraying device moves in the first path R1 in the negative half-axis direction of the longitudinal direction Z of the photovoltaic module a after translating in the lateral direction X of the photovoltaic module a along the first path R1, the inclination angle formed by the flow direction of the fluid and the back surface of the photovoltaic module a is a second inclination angle β, which is an obtuse angle along which the fluid is injected into the photovoltaic module. The second inclination angle beta is preferably 135 degrees.
In the step S3, when the spraying device moves along the beginning or the end of the first path R1, a part of the fluid sprayed by the spraying device acts on the photovoltaic module, and another part of the fluid is sprayed to a non-dismantling area outside the photovoltaic module. As shown in fig. 9, a part of the notch O is located on the photovoltaic module a, and another part of the notch O is located outside the photovoltaic module a.
The advantage of this arrangement is that the edges of the photovoltaic module can be completely cut by the ejected fluid, and edges which are not cut by the fluid (the edges refer to silicon chips, EVA and back plates which are positioned on the peripheral surface of the photovoltaic module) are prevented from remaining on the glass.
As shown in fig. 9, in a state where both the spraying device and the photovoltaic module a are stationary, the slit O formed on the back surface of the photovoltaic module a by the fluid sprayed by the spraying device is substantially annular. As the jetting device and the photovoltaic module are relatively moved according to the set path, a part of the next ring incision O is overlapped in the cutting area formed by the last ring incision O. The annular notch O is formed by the rotation of the fluid, and the rotating fluid has stronger cutting force, so that the backboard, the EVA adhesive layer and the silicon wafer can be peeled off more quickly and better.
The first driving mechanism drives the moving beam 2 to drive the spray head B to move at a speed of 3.5 m/min along the transverse direction X, and the second driving mechanism 14 drives the support 9 to drive the spray head B to move at a speed of 1 m/min along the longitudinal direction Z.

The first driving mechanism drives the moving beam 2 to drive the spray head B to move at a speed of 3.0 m/min along the transverse direction X, and the second driving mechanism 14 drives the support 9 to drive the spray head B to move at a speed of 0.8 m/min along the longitudinal direction Z.

The first driving mechanism drives the moving beam 2 to drive the spray head B to move along the transverse direction X at a speed of 3.3 m/min, and the second driving mechanism 14 drives the support 9 to drive the spray head B to move along the longitudinal direction Z at a speed of 0.9 m/min.
