[0047] 1. Through the hot cutting mechanism side into the broken glass, combined with the hard roll brush machine roll brush effect can be separated from the photovoltaic module, broken glass and photovoltaic module separation effect is good, separation efficiency is high.

[0048] 2. Through the fixed point heating mechanism and grabbing manipulator can separate the battery piece, adhesive film and back plate, the fixed point heating mechanism acts on a single cell, the single point heating effect is good, which can improve the softening efficiency of the adhesive film on the upper and lower sides of the cell and improve the removal efficiency and effect of the cell and the adhesive film.

Manual processing is obviously less efficient. The present application can quickly remove the battery cells and adhesive film fragments by using air suction, thereby improving the processing efficiency.

[0051] 5. Two filters are arranged in the first and second air ducts. The first filter is used to block broken glass, battery pieces and adhesive film, and can filter out dust separately to continue flowing along the air duct. The dust is blocked by the second filter at the tail end of the air duct, thereby achieving the technical effect of separate dust separation.

[0052] 6. The first air cover is located between the two second sliding rails and as close to the hard roll brush machine as possible, so that the distance between the first air cover and the roll brush platform is greatly shortened, thereby shortening the moving time of the roll brush platform when it rises and falls, improving the work efficiency to some extent, and making the layout of each mechanism more compact and reducing the occupied area. The second air cover can also achieve the above technical effects. BRIEF DESCRIPTION OF DRAWINGS

[0072] S2: transferring the photovoltaic module after the preheating in S1 to the cutting platform 202 and fixing (the fixing mode can be fixed clamp fixing or adsorption fixing, and the adsorption fixing is adopted in this embodiment, and the adsorption device adopts a photovoltaic module special suction cup); the hot cutter 201 cuts into the side of the photovoltaic module and shovels off the broken glass A, and the hot cutter 201 is an electric heating type, the temperature is controlled at 250-300 degrees Celsius, and the running speed is controlled at 2 cm / s;

[0073] S3: The photovoltaic module after the broken glass A is removed in step S2 is transferred to the hard brush platform 301 and fixed; the hard brush machine 305 is lowered and the broken glass A remaining on the photovoltaic module is brushed, and the photovoltaic module becomes a glass-free laminate after brushing;

[0074] Step S301: After step S3 is completed, the hard brush machine 305 is moved along the second sliding rail 302 to outside the brush platform, the first hydraulic machine 13 pushes the brush platform 301 upward until the first air duct 7 completely covers the brush platform 301, the first air blower is started, the broken glass A, the film fragments, the battery pieces C and the dust are adsorbed from the upper surface of the glass-free laminate into the first air duct 8, the broken glass A, the film fragments and the battery pieces C are blocked by the first filter screen 9 and then fall into the first discharge duct 11 and then into the broken glass bin 12, and the dust passes through the first filter screen 9 and is blocked and adsorbed by the second filter screen 10;

[0075] S4: The glass-free laminate in step S3 is transferred to the heating platform 401 and fixed;

[0076] S5: The heating device 406 heats one battery unit, and after heating, part of the upper film B and part of the lower film D connected to the battery unit are softened, and the battery unit, part of the upper film B and part of the lower film D connected to the battery unit are clamped out by the grabbing manipulator 5;

[0077] S6: Step S5 is repeated until all the battery units, the upper film B and the lower film D are clamped out (which can be directly placed on the back plate after clamping out, which is convenient for subsequent adsorption), at this time, the glass-free laminate becomes the back plate E, and the back plate E is recycled.

[0078] Step S601: After step S6 is completed, the heating device 406 is moved along the third sliding rail 402 to outside the heating platform, the second hydraulic machine 19 pushes the heating platform 401 upward until the second air duct 14 completely covers the heating platform 401, the second air blower is started, the broken glass A, the film fragments, the battery pieces C and the dust are adsorbed from the upper surface of the back plate E into the second air duct 15, the broken glass A, the film fragments and the battery pieces C are blocked by the third filter screen 16 and then fall into the second discharge duct 18 and then into the broken glass bin 12, and the dust passes through the third filter screen 16 and is blocked and adsorbed by the fourth filter screen 17.

[0079] The application provides a glass A broken photovoltaic module backboard E recycling device and method, which can separate the broken glass A from the photovoltaic module by the side-in hot cutting mechanism 2 and the rolling brush action of the hard rolling brush mechanism 305, and the separation effect and efficiency of the broken glass A and the photovoltaic module are good. The battery piece C, the adhesive film and the backboard E on the backboard E can be separated by the fixed-point heating mechanism 4 and the grabbing manipulator 5, the fixed-point heating mechanism 4 acts on a single battery unit, the single-point heating effect is good, the softening efficiency of the adhesive film on the upper and lower sides of the battery unit can be improved, and the removal efficiency and effect of the battery unit and the adhesive film are improved.

The small broken glass A on the photovoltaic module can be removed by the air suction method, the removal efficiency can be greatly improved, and the worker is prevented from being scratched during the processing of the small broken glass A. The fixed-point heating mechanism 4 and the grabbing manipulator 5 can separate the battery unit, the adhesive film and the backboard E. Since the battery piece C has a large number of battery units, after the operation of the fixed-point heating mechanism 4 and the grabbing manipulator 5 is completed, there are a large number of battery units and adhesive film fragments (including the upper adhesive film B and the lower adhesive film D) to be processed on the backboard E. The processing efficiency is low by manual processing. The battery unit and the adhesive film fragment can be quickly sucked away by the air suction method, and the processing efficiency is high. The first air duct 8 and the second air duct 15 are both provided with two filter screens, the first filter screen is used for blocking the broken glass A, the battery piece C and the adhesive film, and can filter out the dust alone to continue flowing along the air duct, and the dust is blocked by the second filter screen at the tail end of the air duct, thereby realizing the technical effect of separate separation of the dust. The first air cover 7 is located between the two second sliding rails 302 and close to the hard rolling brush mechanism 305 as much as possible, so that the distance between the first air cover 7 and the rolling brush platform 301 is greatly shortened, and the moving time of the rolling brush platform 301 rising and falling is shortened, the working efficiency is improved to a certain extent, and the layout of each mechanism is more compact, and the occupied area is reduced.
